Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a support device for a center cover, such as a meat slicer, which has a center cover in the center of a round blade.

[Background of the idea]

FIG. 3 shows the prior art. Conventionally, the end surface of the shaft 10B of the center cover 10 has a threaded outer shape, is threadedly fitted to the end cover 11, and is further locked with a nut 19 to prevent the center cover 10 from rotating. When slicing hard meat such as frozen meat, especially when slicing thickly, as shown in FIG. is bent in the D direction.
By this bending in the D direction, the green meat 20 is rotated in the B direction, and a force in the C direction is applied to the disk 10A portion of the center cover 10. At this time, the disk 10A is deflected by the force in the C direction and comes into contact with the recess 8 of the round blade 1. When they come into contact, the round blade 1 is rotating, so a force that causes the center cover 10 to also rotate is applied. If the nut is not tightened sufficiently due to the operator's carelessness, the center cover 10 will easily rotate due to the above reasons. There are left-handed and right-handed screws for the threaded part of shaft 10B (round blade 1
The direction of rotation is counterclockwise when viewed from the meat box 7 side),
When the rotational force is applied, in the case of the left-handed screw type, the center cover 10 moves toward the concave portion 8 of the round blade 1 and becomes locked with the round blade 1, making it impossible to remove the center cover 10. In addition, in the case of the right-hand screw method, the center cover 10 moves from the blade surface of the round blade 1 to the meat box 7 side, and hits the part of the meat box 7 close to the cutting edge of the round blade 1, causing the center cover 10 to break. It has drawbacks. Also, round blade 1
If the blade surface of the center cover 10 is not adjusted to be almost flush with the front end surface of the disk 10A of the center cover 10, uneven thickness of the sliced pieces will occur.
This is done by rotating and moving in the axial direction, and after adjustment, the nut 19 is used to lock. Since the round blade 1 is cleaned every time a slicing operation is completed for hygiene reasons, it is necessary to remove and attach the center cover 10 each time, and the above-mentioned adjustment is also required each time, which also has the disadvantage that the adjustment work is tedious. ing.

[Purpose of invention]

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to avoid machine damage due to incorrect operation of this type of meat slicer, and to simplify the installation operation of the center cover.

[Summary of the idea]

This invention focuses on the fact that the shaft does not rotate due to the fit between the non-circular shaft and the hole, and the shaft of the center cover is made non-circular and the relationship between the shaft, piece, and end cover is devised to prevent the center cover from rotating. It is.

[Example of idea]

A specific embodiment of the present invention is shown in FIGS. 1 and 2.

The round blade 1 is attached to the front end surface of the round blade shaft 4, and the pulley 2 is fixed to the rear end of the round blade shaft 4. The round blade shaft 4 is supported by the machine base 5, and the belt 3 is connected to the pulley 2.
is engaged in. The round blade 1 is provided with a circular recess 8 that is concentric with the axis of the round blade shaft 4, and a through hole 9 is provided in the axial center of the round blade shaft 4. The end cover 11 is fixed to the machine base 5 and has a non-circular hole A13.
A piece 14 having a shape is fixedly attached thereto. The center cover 10 includes a disc 10A that loosely fits into the recess 8;
It consists of a non-circular shaft 10B that passes through the through hole 9 and fits into the hole A13. The sleeve 16 has a hole B17 in the center and the outer shape is a lock nut 15.
is screw-fitted with the end cover 11, and further screw-fitted with the end cover 11. Shaft 10B of center cover 10
A screw hole 12 is provided in the end surface of the sleeve 16, and the knob bolt 18 passes through the hole B17 of the sleeve 16 and is screwed into the screw hole 12. On the other hand, the meat box 7 is provided so as to be able to reciprocate toward the round blade 1 using a rail 6 fixed to the machine stand 7 as a guide.

The round blade 1 is rotationally driven by a belt 3, and the meat box 7
is driven back and forth toward the round blade 1 using the rail 6 as a guide. To remove the center cover 10, loosen the knob bolt 18 and pull it out from the round blade 1 side. To install the center cover 10, insert it from the end face of the shaft 10B from the round blade 1 side, and insert it into the hole A1 of the piece 14.
3, and then tighten the knob bolt 18. When the blade surface of the round blade 1 and the front end surface of the disk A of the center cover 10 are made almost the same plane,
When the lock nut 15 is loosened and the sleeve 16 is turned, the sleeve 16 moves in the axial direction.
As the sleeve 16 moves, the center cover 11 also moves, and the level between the blade surface of the round blade 1 and the surface of the disc 10A can be adjusted.

[Effect of idea]

According to the present invention, the shaft of the center cover is made non-circular, the end cover is provided with a piece having a hole that fits into the non-circular shaft, and the end cover of the shaft is provided with a sleeve that is screw-fitted with the end cover. This way, even if the worker forgets to tighten the screws when installing parts after cleaning, the machine will not be damaged. An excellent effect can be achieved in that the trouble of leveling with the surface part can be saved.
