Description

DETAILED DESCRIPTION OF THE INVENTION This invention reciprocates a meat box containing meat blocks toward a round blade installed on one side of the machine base, and also moves the meat boxes up and down during the return stroke of the meat box. The present invention relates to a material feeding device for a meat slicer in which the round blade slices the meat by driving a conveying body that pinches the material.

The material feeding device attached to the conventional meat box has a ratchet wheel and a feeding pawl at the rear end of the material feeding drive shaft, which is horizontally mounted on the side of the box, in order to simultaneously drive the upper and lower transport bodies that sandwich the meat. A one-way rotation mechanism is provided, and the tip of the ratchet lever to which the feed pawl is attached is brought into contact with an inclined cam movably attached to the side of the machine base of the slicer, thereby controlling the movement of the meat box during the backward stroke. Purely mechanical devices are commonly used to convert the material feed motion of the body.
With this conventional device, when the feed rate of the material is increased, the feed operation starts before the front end of the meat box is sufficiently removed from the rotational surface of the round blade, so the thickness of the sliced piece is adjusted to the cross-sectional core shape. There were drawbacks of non-uniformity and a complicated mechanism.
In order to eliminate the above-mentioned drawbacks, the present applicant has developed a method in which a cam that determines the feed rate of the material is formed into a disk shape, and this cam is rotated by a mower fixed to one side of the rock platform. There is a material feeding drive device disclosed in 1975 Utility Model Publication No. 11822, but even in this device, the above-mentioned drawbacks have not been completely eliminated. That is, the feed drive shaft attached to the reciprocating meat box is still operated via a rotation mechanism and a fixed stationary feed amount adjustment mechanism. By mounting the motor for driving the material feeding drive shaft directly on the meat box, the present invention eliminates the need to attach a rotating mechanism and a cam mechanism, and allows the feeding operation to be performed smoothly and to increase the feed rate. This provides a new electric material feeding device that is easy to adjust.

Examples will be described below with reference to the drawings.

The meat box B shown in FIGS. 1 and 2 is driven by a crankshaft 1 that rotates on the top surface of the machine base F, and reciprocates toward the rotating round blade A that is erected on one side of the machine base F. .

This meat box B is provided with a roller-type or blind-type lower conveyor 2 at its bottom, and is connected to a roller-type upper conveyor 4 attached to the tip of an arm 3 having a fulcrum on the side of the box. Take care of the meat loaf stored in meat box B. The above-mentioned upper and lower conveyors 4 and 2 are each driven by a rotating shaft 5 horizontally mounted on the front end of the meat box B, and the transmission mechanism thereof is a conventionally known one, so a description thereof will be omitted. 6 is a helical gear 5' fixed to one end of the rotating shaft 5, and a gear 6' at the front end.
This is the material feed driving shaft constructed on one side of the meat box B by engaging the two.

A clutch/brake unit 7 is connected to an output shaft M'3 via a belt transmission mechanism 9, and is a material feeding motor attached to the same side of the meat box B.

The clutch/brake unit 7, the motor M3, the round blade drive motor M (not shown), and the crankshaft 1.
The female meat box driving motor that rotates the meat box has a circuit configuration shown in FIG. Next, the circuit configuration shown in FIG. 2 will be explained.

The motor M for driving the round blade and the motor M2 for driving the meat box are connected to a power source in parallel with each other via a main switch Sm.

The motor M3 for feeding the material uses a variable distance motor whose rotational speed increases or decreases depending on the voltage increase or decrease, and is connected to a variable speed motor control panel in an operating circuit E provided in parallel with the motors M and G. . This variable speed motor control panel includes a plurality of variable resistors Rn (n is from 1 to 5) in parallel with each other, and ON/OFF of each of the plurality of variable resistors Rn is exclusively selected (as is well known). A select switch Sn (n is from 1 to 5) (similar to the operation switch of a washing machine) is connected. The select switches Sn are arranged in parallel on the front side of the machine base F of the slicer. In addition, a clutch for material feeding
The electromagnetic clutch c and the electromagnetic brake b in the brake unit 7 are connected in parallel to a feed clutch power supply unit connected in parallel to the variable speed motor control panel.
Note that PB is an inching switch. L, L2 are a round blade rotation switch and a meat box drive switch that are linked to a drive control lever (not shown) attached to a conventionally known slicer, and when the drive control lever is placed in the round blade operating position, , switch L closes the b contact, relay Mc is energized and the round blade motor M rotates, and when the lever is placed in the operating position, the switch closes without changing the b contact closure of switch L. L2 closes the b contact, energizes the relay Mc, and rotates the meat box motor M2. Further, L3 is also a switch for stopping the meat box B from the front, which is attached to a conventionally known slicer, and this switch L3 is connected to the self-holding circuit 10 of the switch for driving the meat box. Then, when the operation control lever is placed in the front stop position, the switch L is changed to the after-point close position a, and the meat box B is activated before it reaches the end of the go-around stroke after the up-reading simulation, and the self-holding circuit is activated. 10 is opened, the motor M2 is stopped, and the meat box B is stopped toward the front. The operation of this switch L3 is performed by a cam attached to the crankshaft 1 that drives the meat box B, or a cam directly attached to the meat box B, or the like. Also, the AK connected to this switch L3 is a preset counter,
Cu is a count coil connected to the a contact of the switch L3, cl is a counter clutch coil connected to the self-holding circuit 10 for driving the meat box, and AKb is a count-up switch provided in the self-holding circuit 10. It is. L is a starting switch for the motor M3 for feeding the material. This switch L4 is placed before the actuation timing position of the meat box front stop switch, that is,
The slicer is installed so that its operation timing is adjusted when the meat box B in the backward stroke returns to a position approximately equal to the material feeding start position of a conventional slicer. In addition, this switch L
4 is also operated by the cam attached to the crankshaft 1 or the meat box B' as in the case of the front stop switch L4.
This is done by an appropriate means such as a cam attached thereto. X
4 is a relay connected to the switch L4 for starting the material feed; one of the contacts X4a of this relay X4 is connected in parallel with the switch L4 to form a self-holding circuit 11 of the switch; Contacts X4a and X4b are connected to the material feeding electromagnetic clutch c and electromagnetic brake b, respectively, and actuate them in opposite directions. There are two timers, one for thin slicing and one for thick slicing, connected to the starting switch L4. These two timers T,,T2
The timer contacts T, b, and T2b are connected in parallel with each other to the self-holding circuit 11 of the switch L4 for starting the material feeding, and each forms a switch for stopping the material feeding operation. CS is a switch for changing the material feeding operation. The feed operation selector switch CS uses a cam switch that simultaneously opens and closes a plurality of bushing points, and its installation position is arranged in line with the operation operation lever and the select switch Sn of the plurality of variable resistors Rn. ing. The contact points of this feed operation changeover switch CS are the feed clutch power supply unit, the round blade drive switch L, the meat box drive switch L2, and the self-holding circuit 10 of the switch L2.
, The front stop switch is also a pudding set counter AK.
, timer T, and T2 simultaneous limiting contacts AK, b and A
On each circuit equipped with K2b, the material feeding operation is switched to one of the five operations shown in FIG. 2: continuous, stop, cut, set number of sheets, and intermittent. The relationship between the above operation by this contact and the opening/closing of each circuit is that if there is a circle at the intersection of the circuit and the thin vertical line marked for each of the above operations, that circuit will be closed, and other circuits will be open. This is shown in the figure. In addition, in FIG. 2, PL. , PL2 is the pilot lamp, X,
, X2, and X3 are auxiliary relays, respectively.

Next, the operation of this material feeding device having the above configuration will be explained. In the state shown in Figure 2, main switch Sm
, the material feed motor M3 rotates and the pilot lamp PL lights up.

Next, turn on one of the select switches Sn, set the feed operation changeover switch CS to the continuous position, and then set the operation control lever to the operation position, as described above.
Mazumaru blade A rotates, and then meat box B reciprocates. At this time, the changeover switch CS closes the circuits of the feed clutch power supply unit, relays X, Mc2, switch L3, timer T, and relay X4, as indicated by circles in the figure. Then, when the meat box B returns to the backward stroke and reaches the predetermined position, the switch L4 is closed and the timer T. is energized, and relay X4 is energized to self-hold the switch L4. At the same time, electromagnetic brake b is released and electromagnetic clutch c is engaged. The material is transmitted to the material feed drive shaft 6, the upper and lower conveyors 4, 2 are rotated in the feeding direction via the rotating shaft 5, and the material is sent out from the front end of the meat box B. The motor M3 rotates at a speed corresponding to the resistance value set in the variable resistor Rn connected to the selected select switch Sn. And the above timer T
, when the preset time has elapsed, the time contact T,
Since b opens the self-holding circuit 11 of the switch L, the relay X4 becomes OFH, and the relay contacts X4a and X4b return to their respective states, opening the clutch c, activating the brake b, and transmitting the motor M3. The rotation of the material feed driving shaft 6 is stopped. The above feeding operation is repeated every time the meat box B moves back and forth. Next, the feed amount adjustment operation according to this embodiment includes changing the setting time of the timer T,
Although it is possible to change the resistance value of one variable resistor Rn to change the rotation time or speed of the motor M3, the adjustment operation is mainly made possible by changing the selection of the select switch Sn. There is.

That is, each variable resistor Rn connected to the same switch Sn
By setting appropriate resistance values that are different from each other, the feed amount can be automatically changed by rubbing ONI on the desired switch Sn. In other words, by the combination of the plurality of variable resistors Rn and the select switch Sn, this device digitally stores an arbitrarily set feed amount. Next, when the feed operation selector switch CS is operated with the number of sheets set position, the support point of the switch CS is the power supply unit for the feed clutch,
Relay X,, Mc2, X3, preset counter AK
Since the circuits of , timer T, and relay The number of reciprocations (number of slices) is counted by the preset counter AK via the front stop switch L that operates each time.

When the counted value reaches the set value of the counter AK, the counter switch AKb operates to open the self-holding circuit 10 of the switch for driving the meat box, and the meat box B stops after slicing the desired number of slices. do. Next, when the meat box B is started by setting the feed operation changeover switch CS to the intermittent position and the operation control lever to the operation position, the contact points of the feed operation changeover switch CS are connected to the feed clutch power supply unit, relays X, Mc2, and the timer. The circuits of T3 and relay X4 are respectively closed, and the meat box B is driven only through the self-holding circuit 10 of the switch L2.

Then, when the inner box B reaches a predetermined position in each backward stroke, the material feeding switch L4 closes the circuit as in the case of continuous operation, the clutch c and the brake b are switched, and the material is fed out. At the same time, the timer T2 is energized, and the front stop switch L3 is operated to stop the meat box B from the front. The above-mentioned feed-out operation of the material stops immediately before the meat box B stops, and continues for the set time of timer T2, but during that time, the meat box B has stopped at a position where the round blade A has come off. The delivery motion is not hindered. After the timer L has timed up, the operation control lever is once returned to the stop position, and then placed in the operation position again to start the meat box B. The above operation is repeated to obtain a desired number of thick slices. Its thickness depends on the length of time set on the timer. The off position of the above feed operation selector switch CS is as follows:
When feed operation is not necessary and only meat box B is to be started, the stop position of the switch CS is set to the position where meat box B is stopped when material is first placed in meat box B, and the stop position of the switch CS is These are used, for example, when starting the motor M3, pressing the inching switch PB and engaging the clutch c, and feeding out the material to the front end surface of the meat box B. In addition, in the present invention, the timer ball for setting the feed amount, the operating shaft of the variable resistor, the select switch shaft, etc., and the movement mechanism of the cover plate installed on the side of the round blade in front of the meat box are mechanically or It may be electrically linked.

Further, by directly transmitting the rotation from the material feeding motor M3 or the clutch/brake unit 7 to the rotating shaft 5 at the front end of the meat box, the shaft 5 may be used as the material feeding driving shaft in the present invention. Next, in order to constitute the first invention of the present application, the clutch/brake unit 7 in the above embodiment is eliminated, and the motor M3 for feeding the material loaded in the meat box B is directly connected to the material feeding driving force 6. The switch L4 in the embodiment is connected as a starting switch for the motor M3, and the time contact Tb of the timer T in the embodiment is used, or it is provided movably at an appropriate distance from the starting switch. Connect the mitt switch as a stop switch for the same motor M3.

The function and effect of the material feeding device configured as described above is that when the meat box returns to the predetermined position during the backward stroke, the start switch starts the motor M3 to feed the material, and after a desired time has elapsed, the stop switch is activated. The operation of activating and stopping the motor M3 is repeated every time the meat box B makes one reciprocation. Therefore, the structure of the material feeding device can be simplified by eliminating the conventional one-way rotation mechanism and cam mechanism. In addition, the second application
In order to configure the invention, as in the embodiment, a clutch c is interposed between the driving shaft 6 of the first invention and the motor M3, and the start switch L4 and the stop switch are connected to the clutch c. do.

In the material feeding device configured in this manner, the driving force of the motor M3 rotating in a steady state is transmitted to the material feeding drive shaft 6 when the clutch c is engaged, so that in addition to the effect of the first invention, the material feeding device has the following advantages: It is possible to provide a device that has excellent performance characteristics with respect to increases and decreases in the amount setting. The third invention of the present application uses a variable distance motor equipped with an electric speed control element for the material feeding motor used in the first invention, and operates the speed control element appropriately. The amount of material fed can be adjusted by changing the speed of the motor.

In addition to the motor of the third invention, the fourth invention of the present application uses a variable remote motor M3 whose rotation speed changes by increasing and decreasing the voltage shown in the embodiment, and this motor M3 is connected to a variable resistor Rn, which is also shown in the embodiment. It is constructed by connecting one or a plurality of fixed resistors each having a fixed resistance value through a functional switch such as a cam switch.

The material feeding device configured in this manner can provide a device in which the speed of the material feeding motor M3 can be changed by arbitrarily changing the setting of the resistance value, and the amount of material feeding can be easily adjusted. Note that it is optional whether or not the clutch c of the second invention is interposed in the devices of the third and fourth inventions. Next, the fifth part of the present application
The invention is a motor M for feeding materials loaded in a meat box according to the fourth invention.

The sixth invention of the present application provides that the variable speed motor M3 for feeding the material loaded in the meat box B of the fifth invention includes a plurality of variable resistors Rn connected in parallel to each other, as shown in the embodiment. It is constructed by connecting a select switch Sn that exclusively selects ON/OFF of the resistor Rn.

In the material feeding device configured in this way, the amount of material fed changes depending on the selection operation of the select switch Sn.
That is, by setting arbitrary resistance values that are different from each other in advance for each variable resistor Rn, the desired switch Sn can be turned on.
By setting it to N, the feed amount changes automatically, and the feed amount can be stored in each resistor without having to be adjusted every time the thickness of the sliced piece changes. The seventh invention of the present application is such that the starting switch L4 of the material feeding motor of the first invention includes:
It is constructed by connecting a timer T and its time contact to the self-holding circuit 11 of the start switch L, and depending on the length of time set on the timer T, the amount of material fed, or in other words, the thickness of the sliced piece, can be adjusted. It has been made possible.

In this case as well, it is optional whether or not to use the clutch c of the second invention to change the timer setting time to the clutch engagement time and essentially make it the motor feed operation time. The eighth invention of the present application is to connect a conventionally known meat box front stop switch L3, which is provided with a stop switch to the self-holding circuit 10 of the meat box operation switch L2, in addition to the timer T of the seventh invention. When setting a long time limit on the timer T, the front stop switch L3 is simultaneously used to set the meat box B to a position where it does not interfere with the material feeding while the material feeding motor M3 is operating. It was made to look like it was stopped. The ninth invention of the present application is the eighth invention, in which two or more timers T, , T2 are connected in parallel to the starting switch L4 of the material feeding motor via a feeding operation changeover switch CS, and the meat box The front stop switch L connected to the self-holding circuit 10 of the operation switch L2 is configured to be used simultaneously with one of the timers T2 via the feed operation switching switch CS.
