With this mechanism, regardless of the reciprocating speed of the meat box,
Since the idle time from the stop of the electric motor to the start of braking and the braking time are constant, there is a large difference in the moving distance of the meat box during the idle time, and there is also a difference in the braking distance, so when driving at low speed, the meat box is moved to the front position. There is a problem that the meat box stops before reaching the front stop position, and during high-speed operation, the meat box stops at a position past the front stop position.If the meat box does not stop at the front stop position, the entire width of the meat loaf is
It becomes impossible to cut, and the meat is wasted. In order to correct the front stopping position of the meat box, it was necessary to adjust the position of the protrusion a little.

The flip-flop 15 changes its output to "L" depending on the rising edge of the output signal of the operation switch 10.
to "H". The "H" signal energizes the drive circuit 24 of M 1 and M 2 via the amplifier 23 to rotate M 1 and M 2 , rotate the round knife 9, and reciprocate the meat box 3. , the meat will be cut into pieces. Here, the drive circuit 24 is constituted by an electromagnetic relay, a semiconductor switch, etc. connected in series to the power circuits (not shown) of M 1 and M 2 . AND gate 16 is operation switch 1
0, flip-flop 15, and detector 13
input is input, the output of flip-flop 15 is "H", and the output signal of operation switch 10 is "H"
The output signal of the detector 13 is output to the next stage circuit only after the signal is inverted from "L" to "L". That is, after starting M 1 and M 2 once, the operator returns the operation switch 10 to the original position to stop cutting the meat, and then the meat box 3 approaches the front stop position for the first time. This is sensed by the detector 13 and the signal is transmitted to the AND gate 16 and subsequent circuits. The falling signal of the AND gate 16 that is inverted from "H" to "L" resets the flip-flop 15, and its output signal is inverted from "H" to "L". The "L" signal cuts off the power to M 1 and M 2 via the amplifier 23 and the drive circuit. On the other hand, due to the falling signal of the AND gate 16, the timer 17
is driven to output an "H" pulse signal for a certain period of time (T 0 ). In response to the "H" signal, contact b is opened and contact a is closed at the same time, and the capacitor 20 is charged from the circuit power supply Vcc via the contact a variable resistor 14 and resistor 18. Charging voltage of capacitor 20 V 2
has the characteristics as shown in FIG. The faster the reciprocating speed of the meat box 3 is, the smaller the resistance value of the variable resistor 14 is, and the faster the charging voltage V2 rises. In Figure 3, T A , T B , and T C are respectively high and
This is the braking delay time during medium and low speed operation, and T A < T B

The charging voltage V 2 of the capacitor is compared by the comparator 21, and when V 2 <V 1 , the comparator 21
The output signal of is inverted from "L" to "H". The outputs of the timer 17 and comparator 21 are input to the AND gate 22, and as shown in the time chart f in FIG. 4, after the "H" signal, that is, the braking delay time T, the braking time T' (=T 0 - The "H" signal of T) is obtained. Therefore, the braking times at high, medium, and low speeds are (T 0 - T A ), (T 0 - T B ), and (T 0 - T C ), respectively.
(T 0 −T A )>(T 0 −T B )>(T 0 −T C ). The output signal “H” of the AND gate 22 causes the amplifier 2 to
5, the brake section 26 is driven to stop the meat box 3 at the front position.
