Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a method for peeling a workpiece, such as a radish, which is suitable for use in peeling a workpiece such as a radish by moving it back and forth into and out of a peeling machine. This relates to a holder.

(Conventional technology) Conventionally, when peeling workpieces such as burdock and daikon radish, the workpiece was first washed with water to remove the dirt and mud, and then a knife or peeling tool was used to remove the skin. This was done by hand, but if it was a small amount, it would be fine, but if it gets too large, not only the area around the washing machine but also the worker will be sprayed with mud, which worsens the working environment and makes it difficult to peel the skin by hand. As a result, fatigue accumulates not only in the hands and fingers, but also in the wrists, joints, shoulders, etc., and this fatigue and numbness in the fingers and arms increases, resulting in deep or scratchy skin peeling, which reduces performance and reduces yield. was inviting.

On the other hand, a machine that uses a pair of rollers to peel long and thin workpieces such as burdock and radish has also been proposed, but this kind of peeling machine usually has a brush on the surface. It consists of a pair of rollers that are attached to each other, and as the peeling process progresses,
Dirt accumulates inside the brush and reduces the peeling effect, so not only does a washing process have to be done in advance to remove the mud, but also the peeled shavings accumulate inside the brush, significantly reducing the peeling effect. There were drawbacks such as damage.

For this purpose, the present inventor first proposed
As shown in the publication, a plurality of plate-shaped elastic strip members to which an abrasive material is attached are attached to the surface of a pair of drum-shaped rollers at appropriate intervals based on the peeling action by abrasion, and the elastic strip members are He proposed a peeling machine that utilized elasticity and the abrasive action of an abrasive, and subsequently, as an improvement thereof, disclosed in Japanese Utility Model Publication No. 8231/1983,
The peeling roller is composed of a drum-shaped roller body surrounded by an endless elastic member having a large number of abrasives attached to the outer surface, and an elastic foam is filled between the back surface of the elastic member and the roller. Among these, the latter is widely used in the food processing industry because it improves work efficiency and greatly reduces employee fatigue.

(Problem to be Solved by the Invention) However, in the case of such conventional peeling machines, although the machine itself has an excellent peeling performance and can be operated efficiently without any practical problems, on the other hand, The actual situation is that the work involved in holding the workpiece to be peeled by moving it back and forth into and out of the peeling machine is still done manually by individual employees.

That is, the employee first grasps one end of the workpiece with his hand, then places the workpiece between both rollers of the peeling machine in a circumferential direction, rotating it from side to side and reciprocating it back and forth. The old system is still extremely troublesome and inefficient, in which the workpiece is rotated and peeled to the gripped part, and then the other end of the workpiece is grasped again by hand, and the peeling operation while rotating is repeated. In addition, safety problems remain, such as workers' hands and fingers accidentally coming into contact with the rollers and getting scratches during work.

The present invention has been made in view of the above circumstances, and its purpose is to move the workpiece, such as a radish, to be peeled by moving it back and forth into and out of the peeling machine while turning it left and right, so that it can be peeled from one end surface of the machine. Puncture needles and suction cups that can be easily removed, absorbed, and removed.
To provide a holder for a workpiece for peeling, which can securely hold and remove the workpiece by providing a bent claw at its tip, and also improves the efficiency, safety, and hygiene of the peeling work.

(Means for Solving the Problem) The feature of the workpiece holder for peeling of the present invention to achieve the above object is that the workpiece such as radish can be moved back and forth between the rotating rollers of the peeler. In order to remove the skin of the workpiece, a holder for holding the workpiece is provided with an intake pipe passing through the center of the cylindrical axis of the holding cylinder, and an elastic material is attached to the outer periphery of the tip of the intake pipe. A bowl-shaped suction cup is fixedly held, and the suction cup is provided with a plurality of curved claws with a cross-section shaped like an angle at approximately equal intervals on the back surface thereof, and a plurality of bent claws protruding forward on the outer circumference of the intake pipe on the front surface. On the other hand, an outer cylinder that can be slid back and forth is fitted on the front outer periphery of the holding cylinder, and the outer cylinder has a plurality of claws fixed to the back surface of the suction cup between its tip and a plurality of claws fixed to the back surface of the suction cup. The claw has a spring, and the claw, which normally protrudes in the front axis direction beyond the outer periphery of the suction cup, is pressed when a workpiece is pressed against the front surface of the suction cup and is positioned parallel to the cylinder axis, The outer cylinder is configured to bite into the workpiece when sliding in the forward direction, and a switch for suction/detachment of a suction cup and sliding operation of the outer cylinder is provided on the rear outer surface of the cylinder shaft. It is in.

(Function) According to the workpiece holder for peeling of the present invention configured as described above, when peeling a workpiece such as a radish using a peeler, an operator can use the holder with one hand. Grip the holding cylinder, grasp the workpiece with the other hand, and push one end of the workpiece, that is, the cut end, from the front of the holder to the plurality of piercing needles on the front side while pushing out the elastic bowl-shaped suction cup. When the workpiece is pressed until it reaches the air intake port of the part and the switch is turned on, the workpiece is fixed by suction without shifting in the circumferential direction due to the piercing of the piercing needle, and at the same time, the cut end of the workpiece is always held by the spring. Press the tip of the bent claw that protrudes in the front axis direction beyond the outer periphery of the suction cup using only the elastic force of the suction cup, expand it to an outward position parallel to the holding cylinder axis, and then press the The toe, which is strongly pressed from behind by the forward force of the interlocking outer cylinder, bites directly from the cut toward the front axis of the workpiece, and combines with the suction force to further strengthen the holding force. become.

When performing peeling work by moving the workpiece back and forth into and out of the peeling machine while rotating it left and right, the left and right rotation operation can be easily performed using a holder suitable for gripping, and The piercing needle and bent claw prevent the workpiece from shifting in the circumferential direction and spinning around, and
Due to the bite of the bent claws and the suction force of the suction cup, the workpiece will not fall out even when moving back and forth, and after peeling, the workpiece can be removed by simply turning off the switch and shaking the holder. Therefore, all work that requires manual grasping by workers will be abolished.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a partially cutaway side view showing an example of the holder for a workpiece for peeling of the present invention, and FIG.
