Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a round-blade polishing device for a meat slicer, which is used when polishing a round blade that rotates along a blade surface on a front end surface of a meat box that reciprocates on a machine base.

[0002]

[Prior art]

 For example, as disclosed in Japanese Utility Model Publication No. 4-17359, a round blade polishing device for a meat slicer has two blades, one for the front and one for the back, which are rotatably supported at the tip on a support base of the round blade. The polishing part was rotatably set upright, and it was avoided from the round blade during the slicing operation.The circular blade polishing part was re-supported in the horizontal direction, and the whetstone was touched from the front and back of the rotating round blade. Grinding while rotating the grindstone following the rotation.

[0003]

[Problems to be solved by the device]

 Generally, polishing of a round blade is performed by placing the meat box on the front side of the machine stand, which is out of the rotation position of the round blade, and rotating only the round blade for the convenience of material loading. However, the direction of rotation of the round blade during polishing is the same as in the conventional slicing operation, that is, the direction in which the blade tip cuts while pressing from above so as to be suitable for cutting the material in the meat box (clockwise in Fig. 2). Direction), the abrasive powder generated by polishing also scatters toward the meat box that has stopped at the front side, and must be carefully removed in preparation for the next slice. There was a shortcoming that it took a lot of time and effort to clean the house.

Therefore, it has been a problem to be solved in the round blade polishing apparatus for this type of meat slicer to facilitate the cleaning work after the polishing work.

[0005]

[Means for Solving the Problems]

 Therefore, in order to solve the above-mentioned problems, the present invention is a meat slicer equipped with a round blade polishing section for supporting two blades for the front and back in a freely attachable and separable manner to the round blade, and a motor for the round blade. In the round blade polishing machine, a reversible rotary motor is used for the round blade motor, a round blade polishing switch provided in the slicer operation circuit, and a round blade reversing relay that works in conjunction with this round blade polishing switch. Is provided to provide a round-blade polishing device for a meat slicer having a motor circuit for rotating the round-blade motor in the opposite direction to that during the slice operation.

[0006]

[Action]

 In the polishing device of the present invention, the round blade is rotated in the opposite direction to that during the slicing operation during polishing. The rate of scattering to the side of the round blade opposite to and to the side of the meat box that has stopped before this is extremely low. Therefore, cleaning after polishing work becomes easy. The present invention has solved the above problems as described above.

[0007]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 1 is a round blade which is supported by a tool rest 2 which is erected on one side of the machine base F and rotates with the blade surface vertical, and 3 is slidably supported on the upper surface of the machine base F, Driven by a drive mechanism (not shown), the meat box 4 reciprocates along the front end face along the rotation surface of the round blade 1 has a front end and two grindstones 5 and 6 for the front surface and the back surface which can freely rotate. A round-blade polishing part that supports the wheel and keeps the elevation angle during slicing to avoid the grindstones 5 and 6 from the round blade 1, and 7 is the opposite side of the meat box 3 stopped in front of the machine base F. It is a round blade cover provided on the. The above structure is known in the conventional meat slicer.

Next, the drive circuit of this meat slicer will be described with reference to FIG. 3. In FIG. 3, 8 is a motor circuit and 9 is a driving operation circuit. The motor circuit 8 connects a round blade motor M1 and a meat box motor M2 in parallel to a three-phase AC circuit, and a driving operation circuit 9 includes a round blade polishing switch X0, a slice work switch X1, and an operation switch X2. It has a fixed position detection switch X3, a safety relay M0, a round blade reverse rotation relay MC1, a round blade forward rotation relay MC2, and a meat box operation relay MC3.

From the state shown in FIG. 3, when the round blade polishing switch X0 of the operation control circuit 9 is turned on and the operation switch X2 is turned on, the round blade reverse rotation relay MC1 becomes conductive and the relay contact in the motor circuit 8 is turned on. MC1a is activated, and a current flows through the round blade motor M1 in the opposite direction to that during slice operation, and the round blade 1 is rotated counterclockwise as indicated by the imaginary line arrow in FIG. Then, when the round blade polishing part 4 having the front and back two grindstones 5 and 6 is placed from the retracted position to the polishing position shown in FIGS. 1 and 2 and the above polishing operation is performed, Fine dust such as abrasive powder generated from the upper edge 1'of the blade 1 is scattered along the rotation direction of the round blade 1 toward the round blade cover 7 side, and to the meat box 3 side located on the front side. Adhesion is extremely reduced.

In this embodiment, although not shown, a single select switch is used to serve as the round blade polishing switch X0 and the slice work switch X1 so that both switches X0 and X1 are turned on at the same time. It is configured to never do. When slicing the meat slicer, turn on the select switch to the slice work switch X1 side, turn on the safety relay M0, and then turn on the operation switch X2 to turn on the round blade normal rotation relay MC2. The meat box operation relay MC3 is turned on, the relay contacts MC2a and MC3a in the motor circuit 8 close the circuit, the round blade motor M1 and the meat box motor M2 both operate, and the round blade 1 is shown. It rotates in the clockwise direction of 2 and drives the meat box 3 back and forth.

In addition, in this operation operation circuit 9, the round-blade polishing switch X0 and the slice work switch X1 are both turned off when the select switch is switched during the round-blade polishing or the slice operation. As the time elapses, the safety relay M0 is deenergized and stopped by the operation of the relay contact M0a. Therefore, when restarting, it is necessary to turn off the operation switch X2 and then turn it on again, so that the danger due to careless operation can be prevented.

Although the illustrated embodiment uses two motors for the round blade and the meat box, one motor drives the meat box, for example via an electromagnetic clutch, or For the meat slicer that drives the round blade and meat box with the motor of the stand, removes part of the drive mechanism of the meat box when grinding the round blade, and stops only the meat box to grind the round blade, It goes without saying that the present invention can be adopted by using a reversible rotation motor.

[Effect of device]

 As described above, in a round-blade polishing device for a meat slicer equipped with a round-blade polishing part that supports and attaches two grindstones for the front and back to the round-blade freely, and a round-blade motor, A rotating motor is used for the round blade, and the round blade polishing switch provided in the slicer operation circuit and the round blade reversing relay that works in conjunction with this round blade polishing switch actuate the round blade motor. According to the present invention, which is equipped with a motor circuit that rotates in the opposite direction to that during slicing operation, when grinding a round blade, grind dust such as grinding powder on the side opposite to the meat box that is placed on the front side and stopped. It was ejected, and most of it was attached to the inside of the round blade cover installed on the other side so that the adhesion to the meat box side was minimized, so cleaning the meat box side after polishing becomes easy, and cleaning The time and labor required for . The present invention has excellent practical effects as described above.
