In the embodiment of my invention illustrated in Figures 1 to 4 in the drawings, l designates a slicing machine frame of any desired construction. Uprights 2 connected by horizontal bars 3 are mounted upon one end ofv frame I and form the frame of a magazine 4, more particularly described and claimed in my Patent No. 1,973,919,
issued September 18, 1934, entitled Feeding device.
Knife 9, preferably of the rotary type, is mounted on shaft l9 journaled-in suitable bearings of the frame of the machine, which shaft I9 is connected by chain or belt 20 and suitable pulleys with electric motor 2|. Motor 2| also serves to drive feeding conveyor 8 by means of belt or chain 22 connected by suitable gearing with shaft l9. Conveyor 1 operates to hold the slab in contact with conveyor 8 and may be positively driven or it may receive its motion through the engaged feed mechanism operates to drop the next slab of bacon in position on conveyor 6.
Slices cut from the slab of bacon passing beneath knife 9 fall in overlapping relationship upon endless conveyor 26, as clearly illustrated in Figure 9 of the drawings. Conveyor 26 comprises a series of spaced conveyor elements 21, consisting'of narrow belts or chains arranged on sprocket wheels 26 connected by suitable gearing 6 with conveyor 8. Conveyor elements 21 Moonveyor 26 operate continuously and at a uniform speed when the slicing machine is in operation.
Groups of slices of a predetermined number are spaced on conveyor 26 without stopping conveyor 10 26 or without in any way interfering with the uniform movement of the same by means of a transfer mechanism operative between conveyor elements 21. When a group of slices of a predetermined number has been deposited on conveyor 26, the group is lifted from the conveyor. 26 by transfer mechanism hereinafter described and moved rapidly forward at an accelerated speed greater than the speed of conveyor 26 and redeposited at a suitable distance from that portion of the conveyor previously occupied by said group. The spacing of groups of slices serves to facilitate convenient wrapping and counting of the slices. The transfer mechanism comprises a fork member composed of a series of inverted L-shaped plates 29 interleaved with and normally positioned below conveyor elements 21 of conveyor 26. Plates 29 are mounted on rods 30 and 3| carried by links 32. 'Links 32 are provided with integral upwardly extending arms 33 as illustrated in 3 Figures 3 and 4 of the drawings and the ends of rods 39 and 3|whlch pierce the links 32 and arms 33 are threaded for the reception of nuts 34 and 94a.
A' series of rods 31 constituting a clamping means in operative relation with plates 29 extend from shaft 38 in spaced relation with plates 29. Shaft 38 is journaled in suitable bearings 39 at the upper ends of arms 33 of links 32 and is provided at one end with crank arm 40 pivotally connected at its outer end to the upper end of rod 4 I. Rod 4| is connected at its lower end to leaf spring 43 by means of pivot 42 operative in yoke 44 and eye 45 whereby when the links 32 and plates 29 are moved upwardly by means hereinafter described, rods 31 will simultaneously move downwardly and firmly clamp the group of bacon slices upon the support formed by plates 29. Rods 31 will maintain the individual slices in their proper pre-arrangement during the transfer of the group from one portion of conveyor 26 to another. Spring 43 is suitably mounted on the frame of the machine. I
Forward movement of the parallel motion device is imparted through rotary cam 16 mounted on shaft 64, which cam is provided with lobe 66 adapted to engage roller 66 mounted on shaft 61. Shaft 61 is supported in ears or enlargements 68 integral with extensions 6| of links 41.
Cams 6| and 16 are synchronized such that plates 29 through the actions of lobes 63 and 66 in engagement with rollers 60 and 66 will, first, lift a-group of bacon slices from conveyor 26; second, rapidly move the group forwardly in relation to conveyor; 26; third, redeposit the group of slices upon conveyor 26 and; fourth, return to its normal position for transfer of the succeeding group of slices on conveyor 26, each step of plates 29 being accomplished in succession.
The free end of pivoted track 51 is forked or bifurcated to receive roller 60, maintained by gravity in contact with rotating cam 6|. Roller 56 is partially maintained in engagement with track 51 by gravity and partially by the action of coil spring 69 arranged between eyes 19 and 1| integral with links 32 and 41. Roller 66 is maintained in engagement with cam 16 by coil spring 12 extending between eyes 13 and 14 of links 41 and bracket 15 mounted on the frame of the machine. One or more of each of springs 69 and 12 may, of course, be employed.
Cams 6| and 16 may be connected by any suitable gearing with endless conveyor 26 or otherwise driven in synchronism with knife 9 such that the cams will operate when a predetermined number of slices have been cut to form a group.
In the embodiment of my invention illustrated in Figures 5 and 6 of the drawings, conveyor 26 is composed of two groups of spaced alternating conveying elements 21 and 11, elements 21 comprising a slow moving group and elements 11 a fast moving group.
Conveying elements 21 and 11 are respectively arranged at one end on idler pulleys 18 and 19 rotatably mounted on shaft and, at the opposite end, on drive pulleys 8| and 82, fixedly secured to shaft 83. The varying speeds of conveying elements 21 and 11 are accomplished by merns of the varying diameters of pulleys 8| and 82, pulleys 82 in this instance being the larger.
Conveying elementsv 11 are elevated above conveying elements 21 by means of idler pulleys 94 mounted on shaft 65, suitably positioned so that conveylng elements 11 will intersect the plane of conveying elements 21 between the areas indicated by the letters A and 13" and such that shaft will clear the area B" to permit necessary movement of plates 29 without, interference therewith.
Drive shaft 83 may be driven by an electric motor or other source of power not shown such 35 wheels as and s1, and as and as.
that conveying elements 21 will travel in synchronism with conveyor 8.
In operation. the'cut slices of slab I passing beneath knife 8 are delivered in overlapping relationship to conveying elements 21 of conveyor 26.
when a group of a specified number of slices has been deposited on conveyor 21, plates 28, due tothe operation of the linkage mechanism hereinbefore described, will lift the group of slices from 10 conveying elements 2'! and, at an accelerated rate of speed, carry it forwardly in relation to the movement of conveyor 26 and redeposit the group of slices on conveying elements 11, whence the group ofslices will be rapidly carried to an operator for packaging or other handling.
In the embodiment of my invention illustrated in Figures 7 and 8 of the drawings, I have made a further showing of conveyor 26 composed of slow moving conveying elements 21 and fast moving conveying elements 86, in which the conveying surfaces are maintained at a constant level. Conveying elements 21 are arranged on pulleys 81 and 88, respectively mounted on shafts-89 and 98, while conveying elements 86 are arranged on 25 pulleys 9| and 92, respectively mounted on shafts 98' and 83. Pulleys 81 may be securely mounted on shaft 88. Pulleys 88 are secured to and driven by shaft 98, while pulleys 9| are rotatably mounted on shaft 9|), the pulleys 9| being spaced from pulleys 88 by means of collars lill on shaft 98. Conveying elements 86 are driven by pulleys 92, securely mounted on shaft 93;
driven by an electric motor or other source of power not shown. Sprocket wheels 96 and 98 are of equal diameters while sprocket wheel 91 is'of substantially less diameter than sprocket wheel 99, by which the varying speeds of conveying elements 21 and 86 are manifest. Conveying elements 2! are suitably geared to operate in synchronism with conveyor 8.
45 In this embodiment, the plates 29 are reversed such that the vertical portions thereof will be closely adjacent shaft 89 with the horizontal portions extending in the direction of movement of conveyor 26. It will be understood that the 50 position of plates 29 as shown in Figure '7 of the drawings is not peculiar to this particular embodiment as such structure is equally operable with the other embodiments hereinbefore described, the purpose of reversing plates 29 in this 55 embodiment being merely to provide means for clearing shaft 98 during the operation of the transfer mechanism.
In operation, cut slices of slabs 5 passing beneath knife 9 are deposited upon conveying ele- 60 ments 2'! in overlapping relationship. When a group containing a specified number of slices has been deposited on conveying elements 21, plates 29, due to the operation of linkage mechanism hereinbefore described, will periodically lift successive groups above conveying elements 21 and,
at an accelerated rate of speed, carry them for- Q 7 for slicing machines comprising conveying means including a series of spaced narrow chains arranged to receive slices cut by a knife, a support normally located below the slices deposited by the knife on the conveying means and including -a plurality of slice supporting members interleaved with the narrow chains ,and provided with a plurality of inclined slice receiving surfaces arranged to support the slices in overlapped relation while a group of slices is elevated above the conveying means, means for moving the support upwardly and downwardly to elevate a group of slices above the conveying means and means for moving the support at an accelerated speed from one portion 1 of the conveying means to another portion there- ,for slicing machines comprising conveying means including a series of spaced narrow chains arranged to receive slices cut by a knife, a support normally located below the slices deposited by the knife on the conveying means and including a plurality of slice supporting members interleaved with the narrow chains and arranged to support the slices in overlapped relation while a group of slices is elevated above the conveying means, means for moving the support upwardly and downwardly to elevate a group of slices above the conveying means and means for moving the.
