Description

[Detailed explanation of the invention] Industrial application field This invention is based on a bearing section installed on one side of the meat box.
A double spiral rod-shaped telescopic shaft and a double cylindrical telescopic shaft that advance and retreat orthogonally to the material feed direction are provided parallel to each other in the plane direction, and a width shifting plate is attached to the tips of the pair of telescopic shafts. This invention relates to a width-adjusting device for a meat slicer that supports the material inside the meat box from the width direction between a plate and the other side wall of the meat box and sequentially slices the material from the front end surface thereof.

PRIOR TECHNOLOGY One of a pair of shafts to which a width adjusting plate is attached at the tip is an outer shaft having a threaded portion opposite to each other on both the inner and outer circumferential surfaces, and a threaded portion that is threaded onto the inner circumferential surface of the outer shaft. A double cylindrical telescopic shaft is formed with the formed inner shaft, and the other is formed into a double cylindrical telescopic shaft with an engagement structure of a pin and an elongated hole, and a sprocket is loosely fitted to the outer shaft. , a pin attached to the sprocket engages with a vertical groove provided on the surface of the outer shaft to transmit rotation, and by bearing the outer shaft on a female thread member, the rotation of the sprocket is transmitted between the outer shaft and the inner shaft. For example, Japanese Utility Model Application No. 60-33719 discloses a width adjustment device for a meat slicer equipped with a double telescopic shaft structure in which the width adjustment plate is moved forward and backward by converting the rotation into the screw rotation of the shaft.
There is Utility Model Application Publication No. 151893/1983.

Problems to be Solved by the Invention As mentioned above, in this type of width shifting device, the movement of the width shifting plate causes a forced drive on the side of the double screw-shaped telescopic shaft that is directly connected to the sprocket as described above. On the side of the double cylindrical telescopic shaft supporting the width plate on the other side, there was only an indirect drive that was driven by the movement of the width plate. As a result, operating the handle to rotate the sprocket may feel heavy. In addition, although there is no particular difficulty with the individual double telescopic shaft structure, it is difficult to match the finishing accuracy of both shafts attached to the meat box parallel to the plane without causing twisting, which is difficult in processing and assembly. Since this requires skill and is technically difficult to manufacture, it has been desired to improve the structure of this type of width adjustment device.

Means to Solve the Problems Therefore, the present invention has a double screw rod-shaped telescopic shaft and a double cylindrical telescopic shaft that move back and forth orthogonally to the feed direction of the material, on a bearing section installed upright on one side of the meat box. In a meat slicer width plate device, which is provided parallel to each other in a plane direction and has a width plate attached to the tips of the pair of telescopic shafts, the rear end portions of the double screw rod-shaped telescopic shaft and the double cylindrical telescopic shaft are provided. The present invention provides a width-adjusting device for a meat slicer, characterized in that the two parts are connected to each other by a connecting member that integrally connects them to each other.

Function As described above, the present invention uses a connecting rod to connect the rear ends of the double screw rod-shaped telescopic shaft and the double cylindrical telescopic shaft, which move back and forth orthogonally to the feeding direction of the material, by attaching a width plate to the tip. Since they are integrally connected to each other, the front and rear of the pair of telescoping shafts are fixed in a rectangular shape by the width plate and the connecting member. It is possible to eliminate the instability of the conventional device formed in a rigid body in the shape of a letter, and to eliminate the drawbacks of the conventional device.

Embodiments Examples of the present invention will be described below with reference to the drawings.

In the figure, B is the opposing left and right side walls Ba, Bb
It is equipped with a conveyor device C for feeding materials laid on the entire bottom of the frame shape, and the front end surface is attached to the cutter (not shown in the drawing).
A meat box of a conventionally known meat slicer is driven reciprocally while parallel B', 1 is a bearing part erected on one side of the meat box B, 2 is supported through the bearing part 1, and the conveyor A double-screw rod-shaped telescopic shaft 3 advances and retreats into the meat box orthogonally to the material feeding direction of the device C, and 3 is parallel to the double-screw-rod telescopic shaft 2 in the plane direction, and also slides on the bearing portion 1. The freely supported double cylindrical telescopic shaft 4 is attached to the ends of the pair of spiral rod-shaped and cylindrical telescopic shafts 2 and 3 as described above, and is inserted between the other side wall Bb. A width shifting plate 5 supports the materials loaded in the meat box B from the side according to the width thereof, and the rear end portions 2' and 3' of the double screw rod-shaped telescopic shaft 2 and the double cylindrical telescopic shaft 3 are These are connecting members that are integrally connected to each other.

The double screw rod type telescopic shaft 2 has an outer shaft 2a having threaded portions a and b that are oppositely threaded to each other on both the inner and outer circumferential surfaces;
It consists of an inner shaft 2b with a threaded portion C screwed onto the inner circumferential surface of the outer shaft 2a and a width adjusting plate 4 attached to the tip thereof, and is attached to a sprocket 6 loosely fitted to the outer shaft 2a at a bearing portion 1. By engaging the inner end of the sprocket pin 7 with a vertical groove 8 formed in the longitudinal direction of the upper surface of the outer shaft 2a, the rotation of the sprocket 6 is transmitted to the rotation of the outer shaft 2a. The rotation of the sprocket 6 is converted into the screw rotation of the outer shaft 2a through the screw engagement with the female thread member 9, and the rotation of the outer shaft 2a is The inner shaft 2b is configured to simultaneously cause the inner shaft 2b to undergo a threaded sliding motion and expand and contract as it rotates.

The double cylindrical telescopic shaft 3 includes an outer cylindrical shaft 3a that fits into the bearing part 1, and a width adjusting plate 4 that fits inside the outer cylindrical shaft 3a and has a width adjusting plate 4 at the tip.
By attaching the double screw rod type telescopic shaft 3
and an inner cylindrical shaft 3b that is continuous.

The rear end portions 2' and 3' of both the telescopic shafts 2 and 3 are formed by plugs fitted to the outer ends of the outer shaft 2a and the outer cylindrical shaft 3a, respectively, and the end portions of the connecting member 5 are connected to each other in series by fixing them using setscrews 10, respectively.

Reference numeral 11 denotes a width-shifting operation shaft that is rotatably suspended horizontally in the transverse direction of the bottom back surface of the meat box B, and rotates the sprocket 6 in forward and reverse directions via a chain transmission member 12 provided at its tip.

In this width adjustment device configured as described above, when the width adjustment operation shaft 12 is rotated in one direction, the sprocket 6 rotates in the same direction, and as the sprocket 6 rotates, the double screw rod-shaped telescopic shaft 2 is rotated as described above. Expansion and contraction occur based on screw rotation. The inner shaft 2b of the telescoping shaft 2 moves forward and backward through the width shifting plate 4.
The movement of the outer shaft 2a is integrally transmitted to the inner cylinder shaft 3b, and the movement of the outer shaft 2a is integrally transmitted to the outer cylinder shaft 3a via the connecting member 5.
Both telescopic shafts 2 and 3 extend and contract simultaneously with the forward and reverse rotation of the sprocket 6, and can move the width plate 4 to a desired position.

Effects of the invention In the width shifting device of the present invention, which is configured as described above and operates as described above, the tips of both the telescopic shafts, the double screw rod-shaped telescopic shaft and the double cylindrical telescopic shaft, are connected to the width shifting plate. Since the rear end portions are integrally connected to each other in a series by means of a connecting member, a rectangular one-sided telescopic frame is formed as a whole. Therefore, it is easier to obtain flatness and parallel accuracy for both axes, making processing and assembly easier in manufacturing, and since both telescopic axes move in unison, problems that tend to occur in conventional width adjustment devices of this type. It has practical effects such as eliminating operational drawbacks and allowing smooth operation.
