Abstract

PROBLEM TO BE SOLVED: To provide a food slicer that is improved in operability for an inexperienced operator and is improved in working efficiency and sanitariness for a one-by-one slicing operation, while operational control via a control lever 17a is kept intact. SOLUTION: For a slicing operation via a foot switch 18, a changeover switch 19 is controlled to the corresponding side, and a timer 24 is used to monitor the duration of the ON time T of the foot switch 18. If the ON time is longer than a set time in the timer 24, a circular blade motor 5 and a meat box motor 11 are driven and are kept continuously running by a holding circuit 25, and a later operation of the foot switch 18 releases the holding circuit 25 to stop a circular blade 2 and a meat box 6. If the ON time of the foot switch 18 is shorter than the set time in the timer 24, after the lapse of the ON time of the foot switch 18, a sequencer 20 stops its signal output to stop the circular blade 2 and the meat box 6 after one reciprocation cycle.

[0006]

1 and 2 show an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a front view showing a schematic configuration of a meat slicer.

On the machine body 1, a round blade base 3 which rotatably supports a round blade 2 serving as a processing blade is provided. The round blade 2 is driven by a round blade motor 5 via a belt 4. The meat box 6 serving as a storage box includes a rail 7 fixed to the upper surface of the body 1.
The guide is provided so as to reciprocate toward the cutting edge of the round blade 2. The meat box 6 accommodates a meat lump 13 serving as a work material. The meat lump feeder feeds the meat lump 13 slightly toward the round blade 2 each time the meat box 6 reciprocates in the meat box 6. 14 are provided. The meat box 6 is reciprocated by a meat box motor 11 via a crank mechanism 8, a reduction gear 9, and a belt 10 provided in the body 1. The piece of meat sliced into the round blade 2 in the course of the outward movement is cut out between the round plate 2 and the backing plate 15 provided on the body 1 for adjusting the thickness of the piece of meat to be sliced,
It comes out on the cutting board 16. On the front surface of the machine body 1, a left / right swinging operation lever 17a for operating an operation lever switch 17 for outputting a drive operation signal and a stop operation signal for the round blade motor 5 and the meat box motor 11 is provided. Similarly, a foot switch 18 that outputs a drive operation signal and a stop operation signal for the round blade motor 5 and the meat box motor 11 is connected to the lower floor of the left side cutting board 16 of the body 1 by a cord connected to the inside of the body 1. Have been. Further, a changeover switch 19 for switching between a signal output from the operation lever switch 17 and a signal output from the foot switch 18 is provided on the front surface of the body 1.

FIG. 2 shows the operation of the apparatus of the present invention in the above configuration.
This will be described with reference to the block diagram of FIG.

When a slice operation is performed by turning on the operation lever switch 17 by operating the operation lever 17a as in the prior art, the following operation is performed. When the meat mass 13 is stored in the meat box 6 and the changeover switch 19 is set to the lever operation side, the operation lever switch 17 is turned on by the operation lever 17a while the sequencer 20 receives the lever operation operation signal from the changeover switch 19. Then, the operation lever switch 17
Is received by the sequencer 20, a signal is output from the sequencer 20 to the electromagnetic switches 22, 21, the relay contacts of the electromagnetic switches 22, 21 are closed, and the round blade motor 5 is driven to rotate the round blade 2. At the same time, the meat box motor 11 is also driven, and the meat box 6 reciprocates via the crank mechanism 8, the reduction gear 9, and the belt 10. If the sequencer 20 has not received the lever operation signal from the changeover switch 19, the sequencer 20 does not output the signal for operating the electromagnetic switches 21 and 22 only by receiving the ON signal of the operation lever switch 17. .

As described above, when the changeover switch 19 is set to the lever operation side and the operation lever switch 17 is turned on, the motors 5 and 11 are driven to slice the meat mass 13 in the meat box 6. When the slicing operation is stopped, the operation lever switch 17 is turned off by the operation lever 17a, and the sequencer 20 receives the OFF signal, and the electromagnetic switch 2 is received from the sequencer 20.
2, a relay switch of the electromagnetic switch 21 is opened, the round blade 2 is stopped, and the detection switch 2 (not shown) for stopping the meat box 6 at a predetermined front position.
3 is received by the sequencer 20, the electromagnetic switch 21
And the meat box 6 is stopped.

Next, when performing a slicing operation with the foot switch 18, the changeover switch 19 is set to the foot operation side, and a foot operation operation signal from the changeover switch 19 is transmitted to the sequencer 2.
In the state where 0 has been received, first, the operation lever 17a is operated to turn on the operation lever switch 17. This is because the sequencer 20 does not first receive the operation signal of the operation lever switch 17 in advance at the time of slicing work by the foot switch 18 so that the motors 5 and 11 are not driven even if the operator steps on the foot switch 18 by mistake. This is because, even if the sequencer 20 receives the operation signal of the foot switch 18, no signal is output to the electromagnetic switches 21 and 22. That is, when the changeover switch 19 is set to the foot operation side, the sequencer 20 operates the operation lever switch 17.
Is turned on or the foot switch 18 is turned on only, so that no signal is output to the electromagnetic switches 21 and 22.

When the foot switch 18 is operated for a time longer than the set time To of the monitoring timer 24, a signal is output from the timer 24 to the sequencer 20, and a signal is output from the sequencer 20 to the electromagnetic switches 21, 22, and the electromagnetic switch 21,
The relay contact 22 is closed, and as described above, the round blade 2 starts rotating and the meat box 6 also starts reciprocating. At this time, a signal is also output from the timer 24 to the holding circuit 25,
A signal for holding the signal output from the sequencer 20 to the electromagnetic switches 21 and 22 is sent from the holding circuit 25 to the sequencer 2.
0, the closed state of the relay contacts of the electromagnetic switches 21 and 22 is maintained, and the rotation of the round blade 2 and the reciprocation of the meat box 6 are continued.

When the foot switch 18 is operated again to end the slicing operation, a signal is output from the timer 24 to the holding circuit 25, and the holding circuit 25 is released to release the sequencer 20.
Is stopped, the relay contacts of the electromagnetic switches 21 and 22 are opened via the sequencer 20, and the round blade 2 and the meat box 6 are stopped as in the slicing operation by the operation lever switch 17.

When a single-sheet cutting operation is performed by the foot switch 18, the foot switch 18 is set to a set time To of the timer 24.
If the operation is performed for a shorter time, the sequencer 2
0, a signal is output from the sequencer 20 to the electromagnetic switch 2
Signals are output to the switches 1 and 22, the relay contacts of the electromagnetic switches 21 and 22 are closed, the round blade 2 starts rotating, and the meat box 6 starts reciprocating. Then, the operation of the foot switch 18 is stopped after a time sufficiently shorter than the time that the meat box 6 makes one round trip, so that the signal output from the timer 24 to the sequencer 20 is stopped, and the signal output from the sequencer 20 to the electromagnetic switches 21 and 22 is stopped. Then, the relay contacts of the electromagnetic switches 21 and 22 are opened, and the round blade 2 and the meat box 6 stop in one reciprocation.

In the above embodiment, the sequencer 20 is used as the control means. However, similar effects can be obtained by performing similar control using control means such as a microcomputer and a logic circuit.

[0016]

According to the present invention, in addition to the operation and the stop operation by the conventional operation lever, the operation switch and the foot switch can be used to perform the operation and the stop operation.
The continuous slicing operation and the single-slice operation are switched according to the difference in ON time when the foot switch is depressed, so that even if the meat box is reciprocating at high speed, it can be performed at the feet without reaching for the operation lever. It can be operated at the foot without using hands in the sheet cutting work. Therefore, the work can be easily performed without the need for skill, and the problems of work efficiency and hygiene of the single-sheet cutting work can be solved.
