BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pig skin peeling device.

[0002]

2. Description of the Related Art Conventionally, as a pig skin peeling apparatus of this type, a pair of pinch rolls for horizontally pulling the tip of the skin when peeling with a blade at the time of peeling are arranged horizontally and a vertical type for vertically setting the pinch rolls. There were two types of molds. The vertical type has a small weight of the treatment object that acts on the table because the treatment object (pig) is hung, and it can be peeled off smoothly without supporting the treatment object with rollers etc. On the other hand, there is an advantage, but since the processing body wobbles against the blade, it is necessary for the worker to press the processing body against the blade, and in addition to heavy labor, an accident in which a human body is often caught in the blade occurs. This is a serious drawback.

On the other hand, in the horizontal type, it is necessary to support the processing body by rollers or the like, and according to the prior art, the peeling work section is simply a belt conveyor. According to FIG. 3, the processing body 1
A conveyor 101 for mounting 10 is provided, and the koveyor is conveyed in the direction of the solid line arrow, and the skin 11 of the processing body 110 is conveyed.
The tip of No. 1 is sandwiched between a pair of pinch rolls 103, 104, rotated in the direction of the solid arrow and pulled while being rotated in the direction of the solid arrow (reverse direction) on the guide roller 102, and at the same time blade adjustment not shown. The blade 105 is moved in the direction indicated by the solid line arrow by the operation of the cylinder piston device for the workpiece, and the blade 105 is applied between the meat and the skin of the workpiece 110.
The peeling is performed by utilizing the rotation in the direction of the solid arrow. At the same time, the skin 111 is pulled between the pinch roll pairs 103 and 104 and gripped, and the skin 111 is held by the pinch roll 1.
It is pulled and pulled out by 03 and 104.

On the other hand, according to FIG. 4, when slack 111 'is formed on the peeled skin 111 of the processing body 110, the operator stops the operation of the pinch rolls 103 and 104, and the pinch roll pinches 103 and 104 are removed. The processing body 110 is moved in the direction of the dotted line arrow away from each other by operating the operation switch, and then the slack 11 of the skin 111 is manually rotated while rotating the processing body 110 in the direction of the dotted line arrow.
The slack of the skin 111 was removed by stretching 1 '. Such a manual operation of the operator by the worker is a heavy labor, and the work efficiency is extremely lowered because it is necessary to stop the driving of the conveyor and the pinch roll during the slack removal work, and the skin 111 is pinched. 103 and 10
The slack extension is inadequate in that it is not pulled in between 4 and. The work of manually removing the slack 111 ′ of the skin 111 by manually rotating the processing body 110 in the normal direction was a heavy labor because the friction with the table supporting the processing body 110 was great.
