OBJECTS FOR SUBSEQUENT PACKING Filed June 29, 1961 5 Sheets-Sheet 5 a so. 1 Wilm /mun United States Patent H l 3 Claims. (Cl. 53-240) The present invention relates to an apparatus for forming piles of flat, fragile objects, as for instance biscuits, chocolate bars, or the like for subsequent packing, and particularly to a further development of the apparatus disclosed in applicants prior Patent No. 2,872,020, dated February 3, 1959, in which an endless conveyor means is provided with fingers and associated feeding chutes arranged one after the other in the direction of movement of the conveyor means and in a number corresponding to the number of objects forming a pile.
The apparatus described in said prior patent shows a plurality of feeding chutes in series arrangement above and along a conveyor means which have a bottom grate for the objects to be packed, the bars forming the grate having their forward ends inclined towards the conveyor means in such manner that a pile of objects formed by the previous feeding chutes may pass under the ends of the bars, the lowermost objects being removed from the feeding chutes and advanced by means of fingers. Each feeding chute comprises several channels arranged side by side and at right angles to the direction of feed which form self-contained units and which may be mounted along the conveyor means in any desired number.
Although such apparatus enables a continuous production of piles, difficulties arise when the piles, formed side by side on the conveyor means, are transferred into a packing. It is, therefore, one object of the present invention to provide an apparatus for forming piles of flat, fragile subjects for subsequent packing, which eliminates these deficiencies.
It is another object of the present invention to provide an apparatus for forming piles of flat, fragile subjects for subsequent packing, which includes a supply unit for cardboard or similar shims which is mounted in front of the feeding chutes. The objects ejected from the following feeding chutes are placed on these shims. Furthermore, a cross feeding device is arranged behind the feeding chutes to push the piles on the shim together.
Various types of stiffening shims may be used, which, for instance, may have the exact size of the bottom area of the packing to be produced, or which may be longer than the packing, so that the ends can be bent upwards, enclosing the piles of objects between them and forming a lateral reinforcement of the packing. To bend the ends of the shims, conventional grooving, cutting, and/or bending tools may be provided.
It is yet another object of the present invention to provide an apparatus for forming piles of flat, fragile subjects for subsequent packing, which includes a cross feeding deviceprovided with a member which moves together with the piles to be packed and which reciprocates at the same time. During the continuous movement of the conveyor means, this member is also oscillated, whereby the piles are pushed together. The member is of narrow width so that during its movement it can pass between the fingers of the conveyor means advancing the piles.
With these and other objects in view, which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawings, in which:
FIGURE 1 is a side elevational view of the rear part of the packing machine;
FIG. 2 is a side elevational view of the front part of the packing machine;
FIG. 3 is a top plan view of the front part of the machine shown in FIG. 2; and
FIGS. 4 to 8 are different illustrations showing different stages in the operation of the packing machine.
Referring now to the drawings, as already described in said prior Patent No. 2,872,020, an endless conveyor chain 2 with rakes 3 spaced at certain distances one bebind the other, passes over transport rollers 1. Closely above the horizontally moving part of the conveyor chain 2, smooth bars 4 of plastic material are arranged parallel to and spaced at certain distances from each other, said bars forming togethera grate. The tines of the rakes 3 mounted on the conveyor chain 2 extend through the gaps between the bars 4. Direction of movement is indicated by an arrow in FIG. 1. Each feeding device A to D comprises, for instance, four chute-s or channels 5 in side by side arrangement, separated'from each other by walls 6. In the lower part, the channels 5 are par-. tially covered by plates 7. The chutes 5 and the walls 6 and 7 enclosing them are fixedly mounted to a carrier .8. The latterhas a slot at both sides, so that the carrier 8 may be pushed over holding pins 9 on the lateral supports 10, which arrangement enables the complete feeding device to be easily exchanged. With the aid of a set screw 11 it is possible to secure the chute in its position. The supports 10 are fixedlyymounted; on the guide table 12 along which moves the horizontal part of the conveyor chain 2 with its rakes 3.
The biscuits 13 to be packed are piled up in superposed position in the feeding chutes 5. -The bottom of the chutes is formed of grate-like bars 14 which have an end portion inclined towards the conveyor chain 2. By means of set screws (not shown) the height of the grate bars 14 is adjustable relative to the feeding chute, corresponding with the thickness of the objects 13 to be packed. The bars 14 forming the bottom are adjusted so that the pile of objects just formed may pass through the gap remaining below the front end of the bars 14.
According to the present invention, a supply chute 15 is arranged in front of the feeding chute A, and contains shims 16 or stiff cardboard or similar material. Here, too, the bottom of the chute 15 consists of bars forming a grate 17, the front ends 18 of which being inclined towards the conveyor chain 2 to pass the shims 16 to the conveyor chain 2.
On a shaft 19 a cam disc 20 is fitted with a pusher rod 21 which causes a member 22 to perform a reciprocating movement to eject the shims 16. A transfer and pressure device 23 ensures correct transfer of the shims 16 in such manner that a shim 16 is placed on the bars 4 in front of each rake 3. The shims 16 form the bottom of the packing which will be completed later and receive the piles of objects to be packed.
FIG. 3 is a top plan View showing a series of shims 16 with piles 13 of the objects 13 which are advanced by the rakes 3. V
The shape of the feeding chutes 5 and the channels formed therein ensure that the piles 13' do not collide with each other and that gaps remain between them. To have the piles 13 packed tightly in the final packing, it is necessary to close these gaps. For this purpose, a cross feeding device as shown in FIG. 3 is arranged at the end of the conveyor chain 2, to push the piles 13' together.
On a guide 25, there is a slide 26 which is reciprocated in the direction of the arrow, by means of a rod 27. The slide 26 is provided with a crossbar 28 which guides a rod 29 carrying a flat finger 30. Fixed to the crossbar 28, there is a guide pin 31, controlled by a slotted rod 32. The latter is pivotally arranged on a pin 33 and r a oscillated by a rod 34 at right angles to the direction of movement of the piles 13.
The movements of the control rods 27 and 34 are synchronized so that on the one hand, the finger 30 follows the piles 13' at the speed of the conveyor chain 2 and, on the other hand, is also reciprocated in transverse direction in such manner that the individual piles 13 are pushed together from a position I (PEG. 3) to a position II in which the piles 13 touch each other.
On the other hand, cutting and bending members, which are of conventional nature and the specific structure of which is not the subject matter of the present invention, are provided (not shown) which bend the projecting parts of the shims 16 upwards. This operation is illustrated in FIGS. 4 to 8, the various positions being indicated by letters a to d in FIGS. 4 to 7, while FIG. 8 shows the completed packing.
As is indicated in FIG. 3, the shims 16 are placed on the conveyor chain 2 so that a cut-in rim 16 (FIG. 4) remains on one side. According to FIG. 4, the piles 13 are spaced apart in the position a. When they are transferred into position b, according to FIG. 5, the piles 13' are pushed together, thus leaving another rim 16" on the shim 16. The rims 16' and 16" are cut-in for the following bending operation. When passing into the positions and d (FIG. 3) or as indicated in FIGS. 6 and 7, the lateral projecting rims are bent upwards. After completion of this operation, the stiff shim encloses the piles 13, in this case five of them, so that now the unit can be packed like a rectangular packing by applying a suitable wrapper 35. In the packing shown in FIG. 8, a Wrapper 35 of cellophane is used.
While we have disclosed one embodiment of the present invention, it is to be understood that this embodiment is given by example only and not in a limiting sense, the scope of the present invention being determined by the objects and the claims.
