Description BACKGROUND OF THE INVENTION
This invention relates to a fluorescent lamp crusher device, and
more particularly to an improved, multipurpose such device which
has the capability of accepting and crushing a variety of lamps
of different types and shapes.
There currently are available in the marketplace prior art fluorescent
lamp crushers, such as for example the types disclosed in U.S. Pat.
No. 4655404 U.S. Pat. No. 5205497 and U.S. Pat. No. 5575429
each of which is owned by the Assignee of the present application.
In addition to including means for filtering out mercury vapors
released upon the destruction of fluorescent lamps, these various
patents also disclose additional means for preventing leakage of
such vapors into the atmosphere, and also means for automatically
shutting down the associated crusher machine when the associated
filter elements require replacement. However, with further development
of the nature of gas or vapor filled lamps, it has become necessary
to adapt such prior art machines to accommodate a variety of different
types of lamps, such as mercury vapor, sodium pressure, metal haloid
lamps, as well as more conventional flood and incandescent lamps.
Moreover, since these lamps are now manufactured in a variety of
different shapes, it is necessary for lamp crushers of the type
described to provide means for accepting and safely crushing various
such lamps.
Accordingly, it is an object of this invention to provide an improved
lamp crusher of the type described which has a variety of differently
shaped lamp feed chutes which communicate with the interior of the
crusher machine.
Another object of this invention is to provide an improved such
lamp crusher which is provided with various chute sealing devices
which prevent any undesirable gas, vapors or glass particles from
being discharged rearwardly in the feed chutes from the interior
of the crusher housing.
Still another object of this invention is to provide a machine
of the type described which has means for adjustably mounting the
machine selectively above one of several waste drums into which
crushed glass is discharged.
A further object of this invention is to provide for machines of
the type described means for sensing the contents of an associated
waste drum into which crushed lamps are disposed, and for automatically
shutting down the machine when the contents of the drum reaches
a predetermined level.
Still another object of this invention is to provide for a machine
of the type described an improved crusher blade design which functions
to crush glass into finer, nearly granular size, thereby permitting
a large volume of lamps to be destroyed per waste drum.
Other objects of the invention will be apparent hereinafter from
the specification and from the recital of the appended claims, particularly
when read in conjunction with the accompanying drawings.
SUMMARY OF THE INVENTION
A lamp crusher housing is adjustably mounted on a wheeled rack
to overlie the upper end of one, of a plurality of waste drums mounted
on a pallet beneath the rack. The lower, discharge end of the housing
is releasably and sealingly connected by a plastic sleeve to the
upper end of the registering drum, so that glass fragments from
lamps crushed in the housing drop through the sleeve to the drum.
A cover on the upper end of the housing is secured to the lower
ends of three different chutes, each of which registers with an
opening in the cover so that lamps fed into the upper ends of the
chutes are free to drop through the chutes and into the housing
where they are crushed by rotating crusher bars or flails. A vacuum
pump or fan which is mounted on the outside of the housing communicates
through a replaceable filter element with the interior of the housing
adjacent its lower end.
One chute is circular in cross section and is designed to receive
elongate fluorescent lamps of linear configuration; the second chute
has an oblong, rectangular configuration for receiving circular
and U-shaped fluorescent lamps; and the third chute is nearly square
in cross section and is designed to receive and convey to the crusher
housing mercury vapors, sodium pressure, metal haloid, flood and
incandescent lamps. Each chute is normally closed at its upper end
by a spring-loaded trap door, and the second and third chutes have
mounted intermediate their ends flexible baffle elements extending
transversely of the chute interiors to prevent glass particles and
an air vortex from backing up in the chutes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to FIGS. 1 and 2 10 denotes generally a circular
lamp crusher housing comprising an upper, annular wall section 11
which is integral at its lower end with the upper end of a downwardly
tapered funnel section 12 the lower end of which has formed thereon
an annular discharge section 13. Each of two sets of spaced brackets
15 which project from the outer surface of section 13 adjacent
diametrally oppoisite sides thereof, are fastened to one of two
spaced, parallel, horizontally disposed support bars 16 that form
the upper end of a mobile support rack denoted generally by the
numeral 17 (FIG. 1). Opposite ends 18 of the rack 17 are mounted
on wheels 19 so that the rack 17 can be removably positioned over
a couple of disposal drums D1 and D2 that are supported on a pallet
P.
Secured over the upper, open end of housing 10 is a circular, metal
cover 21. A motor 22 which is mounted on a plate 23 that is secured
to the upper surface of cover 21 has a drive shaft S (FIG. 2) which
extends downwardly through a registering opening in the cover 21
and into the cylindrical section 11 of housing 10 at a point just
offset slightly in one direction from the centerline of housing
10. Releasably secured at their inner ends to the shaft S at 90
degree intervals thereabout, and projecting radially outwardly from
the shaft are four, rigid, lamp crushing bars 24 the outer ends
of which are disposed to travel in a circular path 24' (FIG. 2)
in the housing section 11 when the shaft S is driven by the motor
22.
A flexible, air impervious tube T, which is connected at its lower
end to an opening 14 (FIG. 1) in housing section 13 has its opposite
end secured to the upper end of a filter carriage supporting bracket
25. Bracket 25 is secured at its lower end on blower housing 26
that projects from a motor support 27 that is secured to the rear
of the rack support 17. The end of the tube T which is fixed to
the bracket 25 is connected by a duct 28 to the upper end of a filter
unit F, which contains a removable filter element, for example such
as the type disclosed in U.S. Pat. No. 4655404. A suction fan
motor P, which is mounted on support 27 drives a suction fan or
blower, that is mounted in housing 26 and which is in communication
with the interior of the filter unit F. As noted hereinafter, operation
of motor P creates a vacuum in housing 10 to withdraw objectionable
gases, vapors, particles and the like from the interior of the housing.
To stabilize bracket 25 during the operation of the motor P, a bracket
29 is secured at one end to the cover 21 adjacent to motor 22 and
is fastened at its opposite, upper end to the back of the bracket
25.
Secured at one end by welding, or the like, to the upper surface
of cover 21 and with its lower end in registry with a circular
opening 32 formed through cover 21 adjacent one peripheral edge
thereof, is an elongate, tubular feed chute 31. Chute 31 has in
its upper end a spring-loaded, normally-closed trap door 34 which
is made of metal, and which is hinged along a portion of its edge
to the inside of the chute to pivot into and out of its closed position.
As noted more clearly in FIG. 1 for the majority of its length
the tubular chute 31 is inclined approximately 45 degrees to the
axial centerline of the opening 32 in cover 21.
Mounted adjacent to chute 31 and extending also for most of their
lengths at an angle of approximately 45.degree. to the center of
the housing cover 21 are two additional lamp feed chutes that are
denoted generally by the numerals 41 and 51 respectively. Chute
41 has an upper section which for most of its length is oblong rectangular
in cross section, and is designed to feed into the crusher housing
10 U-shaped and circular lamps. Chute 51 which for most of its
length is square in cross sectional configuration, is designed to
supply mercury, vapor, sodium pressure, fluorescent incandescent
and like lamps to the crusher housing 10.
As shown in FIG. 1 the upper section of chute 41 comprises two,
spaced, parallel side walls 42 and 43 which are secured to or integral
with spaced, parallel end walls 44 and 45. The upper section of
chute 51 has one side wall thereof common with and formed by the
sidewall 43 of chute 41. The other sidewall 53 of chute 51 is spaced
from and extends parallel to the common sidewall 43 and is connected
by a pair of spaced, parallel end walls 54 and 55 with the sidewall
43.
At its lower end the upper section of chute 41 has thereon an external,
lateral flange section 47 projecting in a horizontal plane from
its walls 42 44 and 45 and from spaced portions of its wall 43.
Adjacent its lower end the upper section of chute 51 extends vertically
downwardly and likewise terminates in an external, lateral flange
section 57 projecting from its walls 53 54 and 55 in coplanar relation
with flange 47. The common wall section 43 between chutes 41 and
51 terminates at the bottom of the upper sections of the chutes
41 and 51 and has a lower edge which is coplanar with the chute
flanges 47 and 57. The flanges 47 and 57 register with, and are
secured to, like flanges 47' and 57' (FIG. 2) which are secured
to and bound the upper end of the lower sections of chutes 41 and
51 respectively.
The lower section of chute 41 is defined in part by the walls denoted
by the numerals 42', 44' and 45', which constitute vertical extensions
of the wall 42 44 and 45 respectively; while the lower section
of chute 51 comprises vertical extensions 53', 54' and 55' of the
upper wall sections 53 54 and 55 respectively. To separate the
lower sections of chutes 41 and 51 from each other a rectangularly-shaped
steel plate 58 which is nearly a mirror image of the sidewall 53',
is secured along opposed edges thereof to the inner edges of walls
54' and 55' so that plate 58 registers with the lower edge of wall
section 43 in spaced, parallel relation to wall 53'. The lower edges
of the walls defining the lower sections of chutes 41 and 51 are
secured by welding or the like sealingly against the upper surface
of cover 21 around the opening 60 (FIG. 2) in the cover. This opening,
is generally L-shaped in configuration so that it conforms to the
open, lower ends of the lower sections of chutes 41 and 51. This
enables lamps which are inserted into the upper ends of chutes 41
and 51 to pass through the opening 60 into the crushing section
of housing 10 and into the path of the rotating bars 24 when the
motor 22 is energized.
In use, the lower, cylindrical section 13 of housing 10 is releasably
and sealingly connected by a plastic sleeve PS, such as for example
the type disclosed in U.S. Pat. No. 5205497 to the upper end
of the waste drum D1 which in the embodiment illustrated is positioned
in registry with the lower, discharge end of housing 10. The operation
of the crusher motor 22 and the motor P are controlled by electrical
circuits enclosed in a controller unit C, which is mounted centrally
on the wall 54 of chute 51. When the motor P and crusher motor 22
are in operation, lamps, depending upon the particular shape thereof,
may be inserted selectively into the upper ends of any one of the
chutes 31 41 and 51. The lamps that are to be crushed pass downwardly
through the respective chutes, and through the opening 60 in cover
21 into the path of the rotating crusher bars 24 which then grind
the lamps into small particles that drop downwardly through the
bottom of crusher housing 10 and into the registering drum D1.
Like chute 31 the chutes 41 and 51 have mounted in their upper
ends spring-loaded metal trap doors 49 and 59 respectively, which
are rectangular in configuration and are hinged along one edge thereof
to the inside of the associated chute. After a lamp has been inserted
into a respective chute 41 or 51 and has passed beyond the associated
trap door 49 or 59 such door automatically closes to seal the upper
end of the respective chute 41 or 51. This enables the motor P to
maintain in chutes 41 and 51 the suction or vacuum described above.
Because the lower ends of the chutes 31 41 and 51 are in communication
with the interior of the crusher housing 10 the vacuum created
in this housing by motor P also is maintained at the lower ends
of the chutes and hence to the interiors thereof.
The controller unit C also controls a sensing device 61 which
is mounted in the lower, cylindrical section 13 of the housing 10
in order to sense when the associated waste drum D1 has been filled.
This sensing device 61 which may be in the form of an ultrasonic
sensor enclosed within a sealed housing in a device 61 detects
when the drum D1 is filled, and at such time applies a signal to
a counter circuit which automatically shuts down further operation
of the machine--i.e., interrupt the operation of motor 22 and motor
P, when a predetermined number of drums have been filled. This enables
the filter element of filter unit F to be replaced
In order to make sure that small bulbs entering the lower section
of chute 51 are conveyed into the path of the rotating flails or
crushing bars 24 a spring-loaded steel damper door or plate 62 is
pivotally mounted along one edge thereof (the upper edge in FIG.
1) to the inside of the chute wall 54' beneath its upper edge. Plate
62 extends diagonally downwardly at approximately 45.degree. from
wall 54' and part way across the interior of the lower section of
chute 51. Torsion springs or the like normally urge plate 62 resiliently
into a position of rest in which the plate engages a stop pin 63
(FIG. 1) that extends through wall or plate 58 to overlie the upper
(FIG. 1) surface of plate 62. Bulbs dropping onto plate 62 may,
if necessary, cause plate 62 to pivot downwardly against the resistance
of its associated springs from its position as shown in FIG. 1.
During operation of the crusher unit glass particles and the vortex
created in housing 10 have a tendency to back up into the lower
ends of the chutes 41 and 51. To prevent undesirable entry of such
particles and vortex into the upper section of the chute 51 two
sets of spaced, parallel, flexible baffle elements 66 are mounted
to extend across the upper end of the lower section of chute 51.
For example, as shown in FIG. 2 six such elements 66 of each set
are secured at one of their ends to the upper edges of walls 53'
and 58 respectively, and project at their opposite ends part way
across the chute into confronting, partly overlapping relation to
each other.
Also, a solid, flexible baffle 65' is secured at one end to the
chute wall 55 adjacent its juncture with wall 55', and extends part
way across the interior of chute 51 above the elements 66; and each
of a set of five, spaced, parallel, flexible baffles 67 is secured
at one end thereof to chute wall 55 above the baffle 65' and extends
part way across chute 51.
In chute 41 one flexible baffle element 69 is secured at one end
to the chute wall 45 adjacent the upper end of chute 41 and extends
part way across the interior of chute 41.
By way of example, the flexible baffle 65' may be made from a thick
piece of rubber which normally is free to bend part way downwardly
in chute 51 relative to its upper or left-hand edge, which as shown
in FIG. 1 is secured along its length to the inside surface of the
chute wall 55. The lower portion of the baffle element 65' is therefore
free to bend downwardly when engaged by an incoming lamp; and after
the lamp has passed the element will tend to return to the position
as shown in FIG. 1. Likewise, the set of spaced, parallel, flexible
baffle elements 67 are also free to hang slightly downwardly in
the chute 51 above element 65', and when engaged by an incoming
lamp, also are free to bend further downwardly into the chute 51
to permit passage of the incoming lamp or lamps. Elements 67 then
tend to return to their positions as shown in FIG. 1 wherein, like
element 65', they tend to prevent pieces of glass and the vortex
that is generated in housing 10 from backing upwardly into the chute
51. Baffle elements 67 can be created by slitting a rectangular
piece of rubber along parallel lines extending normal to the edge
of the baffle set which is fastened to wall 55. Likewise, the flexible
baffle element 69 may be made from a strip of rubber material which
is free to bend downwardly in chute 41 relative to its fixed, upper
edge, and like the baffle elements 65' and 67 functions to prevent
any undesirable particles of glass and the vortex in housing 10
from backing upwardly into the upper end of chute 41.
When the machine is operating and the vacuum is generated in the
lower end of housing 10 the free ends of the two sets of baffle
element 66 which also may be made from strips of rubber, are free
to bend downwardly in the lower section of chute 51 relative to
the fixed edges thereof. In FIG. 2 the free ends of the baffle element
66 are shown as they appear when they are bent slightly downwardly,
thus creating a slight space between the confronting ends thereof.
In practice, however, one set of baffle element 66 is made slightly
longer than the other, so that when the machine is not operating,
the confronting ends of elements 66 slightly overlap one another.
Also, to help maintain the spring-loaded trap doors 34 49 and
59 in their closed positions, a strip of flexible magnetic material
may be mounted on the inside of each chute to engage marginal edge
portions of the respective doors when they are in their closed positions.
The baffle elements 66 not only prevent glass particles from passing
upwardly into the chute 51 but also help to prevent the circulating
air or vortex generated within housing 10 from backing upwardly
into the chute 15.
From the foregoing it will be apparent that the present invention
provides very effective means for permitting a large variety of
lamps of different sizes, shapes and composition to be crushed and
disposed of in a single machine. The three chutes 31 41 and 51
include in their upper ends spring-loaded trap doors which normally
remain closed; and chutes 41 and 51 include the additional baffle
elements 66 65', 67 and 69 which prevent any undesirable backup
of glass particles and vortex into the chutes 41 and 51. Moreover,
the spring-loaded damper door or plate 62 in the lower section of
chute 51 guides small incoming bulbs directly into the path of the
rotating crusher members 24 in housing 10. The rigid crusher members
24 are releasably secured at their inner ends to a hub on shaft
S so that they can easily be replaced, and in operation grind the
incoming glass into finer particles than prior such flails, thereby
permitting a larger quantity of crushed bulbs to be stored in a
respective disposal drum D1 or D2. Also, when drum D1 becomes filled,
as evidenced by a signal generated by the switch 61 the brackets
15 can be disconnected from their illustrated positions on the support
bars 16 and may be shifted laterally to position the crusher housing
10 over the other drum D2 which then is connected by a plastic
sleeve PS to the discharge end of housing 10. This considerably
expedites the crushing of lamps. Likewise, of course, the wheel
mounted rack 17 permits the rack and the crusher housing 10 supported
thereon to be easily transported to and from a pallet P on which
the drums D1 and D2 are supported.
Although in the illustrated embodiments flexible baffle elements
have not been illustrated in chute 31 it will be apparent that
one or more such elements may be installed in chute 31 without departing
from this invention.
While this invention has been illustrated and described in detail
in connection with only certain embodiments thereof, it will be
apparent that it is capable of still further modification, and that
this application is intended to cover any such modifications that
may fall within the scope of one skilled in the art or the appended
claims. |
