Description

[Detailed description of the invention] This invention relates to a material feeding device attached to a meat box of a meat slicer, and is an improvement on the conveyor belt that sends out the materials loaded in the meat box.

The material feeding conveyor of the meat slicer uses a large number of parallel wire rods with a certain gap between them, and both ends of the wire rods are connected in an endless chain to form the conveyor belt of the meat box. In the case of the applicant's earlier application,
Utility model registration application No. 63136 was filed in 1933.

The above-mentioned conventional conveyor is formed into an endless chain by bending both ends of each wire rod over the end of the next wire rod, which makes it difficult to maintain a constant pitch. There was a point where the conveyor belt was easily stretched.

In order to eliminate the above-mentioned conventional drawbacks, the present invention forms the middle part of each wire to have a rectangular cross section, forms journal parts at both ends, and connects the journal parts to a pair of left and right parts along both sides of the wire. By inserting it into the roller shaft of the chain link, and fitting both ends of the intermediate part into the square holes provided on the inner surfaces of the left and right link plates facing each other with the intermediate part in between, with the corners aligned vertically. Both sides of each wire rod are connected endlessly with chain links to form a material feeding conveyor.

Embodiments of the present invention shown in the drawings will be described below.

In the figure, A is a round blade that rotates on one side of the machine base F of the slicer, B is a meat box that travels back and forth on the machine base F towards the round blade A, and C is placed at the bottom of the meat box B. A conveyor belt for material feeding rotates intermittently in the counterclockwise direction as shown in the figure following a conventionally known material feeding drive mechanism (not shown) that is started during the backward stroke of the meat box B, 1 is a conveyance surface C of this conveyor belt C ′
A is the middle part of the wire 1 formed with a square cross section, b is a journal part with a circular cross section formed at both ends of the wire 1, and 2 is an endless chain link along both sides of the wire 1. It is.

The journal parts pass through the roller shafts of the chain link 2, and their outer ends are caulked to the outer link plate 2a.

Further, both ends a' of the intermediate portion a of the wire are fitted into square holes 3 of the same shape formed so that the corners are vertically aligned with the inner surface 2b' of the inner link plate 2b. ,
The wire rods 1 are lined up parallel to each other with a certain gap between them and in a certain posture with their corners facing up and down, and are connected at both ends in an endless chain with chain links 2. It resembles the conveyor belt C mentioned above.

4, the conveyor belt C is stretched between the front and rear sprockets 5 and 6, and is detachably attached to the bottom of the meat box B by a pair of front and rear support shafts 7 and 8 that are inserted in the transverse direction and are freely inserted and removed. The fitted conveyor frame, 9 is a feed roller suspended horizontally in front of this conveyor frame 4, 10 is a drive shaft inserted through this roller 9, and together with the support shaft 7 at the front end of the conveyor frame 4, the above-mentioned not shown They are respectively coupled to and detachably connected to the material feeding drive mechanism.

In this embodiment, the square hole 3 into which both ends a' of the intermediate portion a of the wire are fitted is connected to another inner link which is fixed substantially integrally with the inner link plate 2b as shown in FIGS. It is provided on the plate member 12.

This plate member 12 is a chain link play) 2b
Two front and back members 1 each having an oblong shape of approximately the same shape as
2a and 12b, the front member 12a along the link plate 2b is provided with a round shaft hole 12a' into which the journal portion of the wire 1 is fitted, and the inwardly bent edge of the front member 12a The square hole 3 described above is provided in the back member 12b that is fitted onto the outside.

Then, by caulking the outer end of the journal part that has passed through the roller shaft, the step formed by the connecting part between the intermediate part a and the journal part comes into close contact with the mouth edge of the shaft hole 12a', and the wire rod One link plate 2b of the chain link 2 is fixed to both sides of the chain link 1.

In carrying out the present invention, the inner link plate 2b of the chain link 2 in the above embodiment is made of a sufficiently thick material, and a square hole 3 is provided on the inner surface thereof into which the square end l of the wire rod 1 is fitted. Alternatively, the front member 12a may be omitted and the back member 12b provided with the square holes 3 may be directly fixed to the inner link plate 2b.

It goes without saying that the present invention is applicable not only to the lower conveyor of the slicer, but also to the upper conveyor.

As described above, in the present invention, the intermediate portion forming the conveying surface of the conveyor belt is formed into a rectangular cross section, the journal portions are formed at both ends of the wire rod, and the journal portions are connected to the rollers of the pair of left and right chain links. By inserting the wire into the shaft, both ends of a large number of wire rods are connected by an endless roller chain, so the pitch of each wire rod with a relatively wide interval is constant, improving parallelism accuracy, and improving parallelism compared to conventional wire rods. Belt elongation during use, which tends to occur with manufactured conveyors, can be minimized.

In addition, in the present invention, the middle part of each wire has a rectangular cross section,
Both ends of the square shape were fitted into square holes provided on the inner surfaces of the left and right link plates with the corners aligned vertically, so that each wire had the ridge of the square shape in the middle part aligned in the vertical direction. They line up to form a conveying surface, and when slicing materials, especially hard materials like frozen meat, each corner of the material is embedded in the material to ensure precise feeding without slipping. This has a practical effect.
