Description

[Detailed description of the invention] This invention was developed by arranging a large number of wire rods in parallel with almost constant gaps between them, and connecting both ends of the wire rods in a chain to create an endless sash-like conveyor belt. The present invention relates to a lower conveyor for a meat slicer, in which the conveyor belt is stretched over a conveyor frame having front and rear support shafts, and laid within a lower frame forming the bottom of a meat box.

For example, in the meat slicer in which the lower conveyor belt of the slicer is formed using a wire rod as described above, there is a patent application for utility model registration No. 63136 filed in 1975 in the applicant's earlier application.
There is a number.

The cover plate inserted into the back side of the conveyor belt of the conveyor belt in the above-mentioned prior application was formed from a single sheet metal whose rear edge was slightly bent downward.
If the wire rods subjected to the load of the meat blocks loaded in the meat box are bent, although this is extremely rare, the trailing edge of the plate may intervene between the conveyor belt formed by the wire rods, resulting in a serious accident. There was a danger that this could lead to

In order to eliminate the above-mentioned drawbacks of the conventional belt, the present invention improves the cover plate that is inserted into the back side of a lower conveyor belt formed by connecting a large number of parallel wire rods in a chain.

That is, a fixed cover plate is attached to the upper surface of the conveyor frame along the back surface of the conveyor belt, and a rear edge is formed in a cylindrical shape by overlapping the front edge on the rear edge of the fixed cover plate. The slicer can be used safely by installing an auxiliary cover plate that is wrapped around a shaft horizontally suspended at the rear of the conveyor frame and attached to the rear rear surface of the conveyor belt. .

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

In the figure, A is a rotating round blade that is installed upright on one side of the machine base F of the slicer, and B is driven by a motor (not shown) installed inside the machine base F via a crank 1 and a connecting rod 2.
A meat box C is a rectangular box that forms the bottom of the meat box B, which is guided by a front rail 3a and a rear rail 3b attached to the machine stand F, and runs back and forth horizontally along the rotating surface of the round blade A. This is a lower conveyor installed on the lower frame B'.

Conveyor belt 10 stretched between the front and rear support shafts 5 and 8
It consists of

The conveyor belt 10 is formed into an endless blind shape by arranging a large number of metal wire rods a in parallel to each other at appropriate regular intervals and connecting both ends to the next wire rod a.

In this embodiment, the wire a is produced by bending both ends a' of the wire a in one direction and winding the end a' around the end a' of the next wire a in a chain shape, as shown in the drawing. , both ends of which are connected in a chain with a certain gap between them.

Further, each of the wires a has a middle portion having a rectangular cross section except for the above-mentioned both ends.

C' is the conveying surface of the material meat mass formed by the upper surface of the conveyor bell (10) using the wire rod a.

11 is a fixed cover plate attached to the upper surface of the conveyor frame f via setscrews 12 inserted through the four corners, and is interposed along the back surface of the conveyor surface C' of the conveyor bell); 13 is this fixed cover plate; This is an auxiliary cover plate that extends rearward of 11 and is also interposed along the back surface of the conveyance surface C'.

This auxiliary cover plate 13 is a fixed cover plate 1
The front edge 13' is superimposed on the rear edge 11' of the turnbuckle arm 7, and the cylindrical rear edge 13'' is fitted onto the shaft 9 except for the rear end of the turnbuckle arm 7. There is.

This lower conveyor C having the above configuration has a cylindrical rotation driving shaft 4 and a fixed connecting rod 6 connected to a conveyor frame f.
The meat box B is removably installed at the bottom of the meat box B by two mutually parallel support shafts 14a and 14b, which extend through the lower frame B in the transverse direction.

Note that the shaft 9 that supports the rear support shaft 8 has both ends connected to the lower member B.
It is fitted and supported by a latching step 16 formed on the inner surface of the holder.

The support shafts 14a and 14b both have a head 14' having a handle 15 at their outer ends (lower side in FIG. 2), and are removably fixed to the lower frame B' by a pair of setscrews 17. By removing the front side wall Ba of the meat box B, it is possible to extract it from the above-mentioned supported state, and by removing the support shafts 14a and 14b, it becomes possible to take the lower conveyor C out of the lower frame B'. .

The front support shaft 14a has a hexagonal cross section, and its inner end can be freely inserted into and removed from a shaft joint 18' that is pivotally supported by a lower frame B' to which the other side wall Bb of the meat box B is attached. The conveyor drive shaft 18 is rotated by a conventionally known conveyor drive shaft 18 extending in the extending direction of the shaft joint 18'.

The rotary drive shaft 4 fitted with the support shaft 14a has a hexagonal shaft hole on its end face, rotates together with the support shaft 14a, and supports the conveyor belt 10 through the support shafts 5 at both ends. 1
Drive counterclockwise as shown in the diagram.

The conveyor drive shaft 18 is driven by the movement of the meat box B during the backward stroke through a material feeding mechanism of a conventionally known slicer, a part of which (bell crank 19, crank connecting rod 20) is shown in FIG. The lower conveyor C is intermittently driven.

In addition, in the figure, 21 is a feed-out roller horizontally suspended parallel to the rotation shaft 4 at the front end of the lower frame B', and 22 is a feed roller having the same structure as the support shaft 14a, through which the roller 21 is inserted. A rotary shaft 23 that also intermittently drives the roller 21 via a conventionally known chain drive mechanism (not shown) provided between the drive shaft 18 and the drive shaft 18 swings along the outside of the side wall Bb of the meat box B. An upper conveyor is attached to the tip of a movably attached arm 24 and fitted into the meat box B. This conveyor 23 is provided at the pivot base of the arm 24 and is driven by the chain drive mechanism. Gear transmission mechanism (
It is intermittently driven together with the lower conveyor C and the feed roller 21 via a conventionally known interlocking mechanism consisting of a chain drive mechanism (not shown) and another chain drive mechanism (not shown) provided in the same arm 24.

Conveyor belt 10 using wire rod a as described above
This lower conveyor C is provided with a fixed cover plate 11 and an auxiliary cover plate 13 on the back side of the conveying surface C'. Even when the gap is enlarged, the rear edge 13'' of the auxiliary cover plate 13 is formed into a cylindrical shape and is in close contact with the shaft 9 at the rear end, which is one turning point of the conveyor belt 10. The rear edge portion 13'' does not intervene in the gap of the wire rod a enlarged by the above deformation.

Also, when the turnbuckle-shaped arm 7 is extended in response to the elongation of the conveyor belt 10 due to use,
Since there is an overlapping portion formed between the rear edge 11' of the fixed cover plate 11 and the front edge 13' of the auxiliary cover plate 13, the conveyor belt 10 can be adjusted without creating a gap between them. .

As described above, according to the present invention, it is possible to safely use a meat slicer in which the conveyor belt is formed using a wire rod in order to facilitate cleaning of the lower part of the conveyor belt, and to use a conveyor that is adaptable to the adjustment of the conveyor belt. I can do it.
