Description

The present invention relates to a meat feeding device in a meat slicer equipped with a meat feed rotating body and capable of slicing a meat block fed from a meat box reciprocated by a crank mechanism by a round blade rotating at a fixed position.

The meat feeder of the conventional meat slicer related to the present invention includes, for example, a meat feeder in which the upper and lower meat feed rotating bodies sandwiching the meat chunk as in Patent Document 1 are placed horizontally on the side of the meat box so that they can be driven simultaneously. At the rear end of the drive shaft, a one-way mechanism consisting of a ratchet wheel and a feed claw is provided, and by making contact with a slope cam attached to the machine base of the slicer, the movement of the meat box when it moves backward is converted to a movement of meat feed Such devices are widely used.
This meat feeder operates in conjunction with the movement of the meat box, so it does not require a separate interlocking mechanism, but it is convenient. However, in order to increase the processing capacity, the meat feeder is synchronized with the movement speed of the meat box being increased. The feeding speed was also increased, and a slip phenomenon occurred on the feeding surface, and the meat block was not reliably delivered.

In contrast to the mechanical device described above, there is one disclosed in Patent Document 2 as a device that uses an electric motor as a drive source for feeding meat. In this meat feeder, a technique is described in which the feed amount is adjusted by shifting the meat feed motor or changing the rotation time.

The present invention provides a meat slicer that can obtain a stable meat feed amount regardless of the number of reciprocations of the meat box and the size of the meat feed amount and is not obstructed by the round blade during the meat feed and has good operability. An object of the present invention is to provide a meat feeder.

According to the present invention, a meat box equipped with a meat feed rotating body driven by a meat feed motor is reciprocated within a predetermined range in synchronization with the rotation of the crankshaft via the crank mechanism by the meat box motor. a meat mass fed in the course by meat feed rotary member a meat slicer is capable sliced by circular blade rotating at a fixed position, and the operating time of the meat feed motor speed is fixed to a variable An adjustment means for adjusting the amount of meat feed, a speed change means for the number of reciprocations of the meat box, and a detection means for detecting the rotational speed and rotational angle position of the crankshaft, and the meat box at the start position of the reciprocation Between the round blades, there is a gap C of 1/2 or more of the movement distance of the meat box corresponding to the operation time of the meat feed motor that can obtain the maximum meat feed amount when the number of reciprocations of the meat box is the maximum. provided, the meat box reciprocating By setting the number and meat feed amount, meat feed motor, only about 1/2 of the operating time of the meat feed motor meat feed amount set is obtained, starting at the timing before the meat box is returned to the start position It was made to be.

According to the present invention, if the number of reciprocating movements of the meat box that determines the work efficiency and the meat feed amount that determines the slice thickness are set, the meat box is quickly moved by the time corresponding to the meat feed amount before the meat box returns to the starting position. Since the feed motor is started, a stable slice thickness can be obtained regardless of the work efficiency and the slice thickness.

The side view which shows the principal part. Explanatory drawing which shows typically the relationship position of the reciprocation of a meat box and a round blade, and the timing of meat feed. Control block diagram.

The meat feeder of the meat slicer which implemented this invention is demonstrated referring drawings.
The machine 1 of the meat slicer of the present embodiment is a box, and the meat box 2 on which the meat chunk is placed is provided with a bottom conveyor 4, an upper roller 5, and a side conveyor 6 as a meat feed rotating body. The meat feed motor 3 is connected to the meat feed motor 3 through a transmission mechanism and is driven to rotate synchronously.
The meat feed motor 3 is a servo motor attached to the meat box 2, and the meat feed speed is fixed to about 60 mm / second as a speed at which the feed amount can be reliably obtained without causing slippage on the feed surface. The meat feed amount that determines the slice thickness is determined by adjusting the operation time of the meat feed motor.
In addition, a margin plate 7 is provided on the opposite side conveyor 6 side of the bottom conveyor 5 so as to be adjustable in the width direction.
The support body 8 supporting the meat box 2 configured as described above is supported by a horizontal support shaft 9 laid horizontally on the bottom of the machine body 1 and is driven by a meat box motor 10 to which an inverter is connected as a transmission means. The crank mechanism 11 is configured to reciprocate within a predetermined range about the axis of the horizontal support shaft 9.

A round blade 8 is provided at an upper fixed position of the machine body 1. The round blade 8 is disposed so that the front end surface of the meat box 2 is along the rotation surface, and is supported by the machine body 1 so as to rotate in the vertical direction. .

The meat slicer configured as described above is a conventional slicer that feeds a predetermined amount of meat lump placed on the meat box 2 by a meat feed rotating body and swings it toward the rotating round blade 12 to slice. However, the gist of the present invention will be described below.

FIG. 2 is an explanatory view schematically showing the reciprocation of the meat box 2 relative to the round blade 12 and the timing at which the meat feed motor 3 for driving the meat feed rotating body is started.
The meat box 2 is simply displayed in a square shape, but actually means the size of the cross section of the largest meat block that can be placed on the meat box 2 and can be sliced by the round blade 12.
Further, the reciprocating motion is displayed by replacing it with a linear motion instead of a swing for simplicity.

The meat box 2 is reciprocated by a crank device 11 connected to the meat box motor 10 between a start end position AA indicated by a solid line and a terminal end position BB indicated by a virtual line with respect to the start end position side end. However, in order for the meat block placed on the meat box 2 to be completely cut off, at least the upper and lower corners of the meat box 2 at the end position BB as shown in FIG. In other words, it is necessary to reach the cutting edge circle.

A gap C is provided between the meat box 2 and the round blade 12 at the start position AA. This gap C is the maximum speed that the meat box motor 10 is allowed, that is, the maximum number of slices, and even if the meat feed amount is also the maximum value that is allowed, that is, the maximum slice thickness, the maximum meat feed amount is The space is a space having a distance of 1/2 or more of the movement distance of the meat box 2 corresponding to the operation time of the meat feed motor 3 to be obtained.
This gap C is the minimum gap where the meat block does not interfere with the round blade 12 even if the meat feed of the maximum slice thickness is performed at the maximum efficiency, but corresponds to the meat feed amount because the meat box 2 reciprocates. The moving distance of the meat box 2 to be moved may be 1/2 or more.

Next, the timing for starting the meat feed motor 3 will be described. In order to feed the meat block without interfering with the round blade 12 as shown in the lower part of FIG. 2, the side of the round blade of the meat box 2 (meat block) is a round blade in the return path of the meat box 2 The position must be terminated after the meat box 2 returns to the starting position from the position DD where the twelve cutting edges are distant and then returns to DD again.
The timing for starting the meat feed motor 3 when the maximum meat feed amount is required is schematically shown in the lower part of FIG. 2, but the right end of the meat box 2 reaches the DD position on the return path. When this occurs, the meat feed motor 3 is started. When the meat box 2 returns to the starting position from there, the distance corresponding to the gap C is moved, and the movement time during that time corresponds to 1/2 of the operation time of the meat feed motor 3 at the maximum meat feed. While the meat box 2 that has returned to the start position moves forward and the right end reaches the DD position via the gap C, the remaining half is sent and completed.

The timing at which the meat feed motor 3 is started when the amount of meat feed to be set is small (when the slice thickness is thin) is also the start position A− for approximately half of the time required for the meat box 2 to feed the meat. If it is started at the timing before returning to A, the meat feed centering on the start position is performed.
Thus, since the meat feed is always performed when the meat box 2 at the start position is stopped or at a low speed, accurate feeding can be performed.
In particular, when the side conveyor 6 is provided, when the meat box 2 returns to the starting position, the meat block is pressed against the side conveyor 6 by inertia, so that the feeding action is good.

Next, control for controlling the operation will be described with reference to FIG.
Meat boxes motor 12 connected to the inverter as the shift means of the reciprocating number of meat boxes (which is also the immediate Chi slice number) from the sequencer (trade name) of the control means in accordance with the reciprocating frequency of meat box 2 set And the meat box 2 is reciprocated via the crank mechanism 11.

The meat feed motor 3 for driving the meat feed rotating body has a fixed rotation speed, and the operation time of the meat feed motor 3 is calculated by a sequencer so that a meat feed amount corresponding to the set slice thickness can be obtained. Based on the result, the operation is controlled via the servo drive.
As for the timing at which the meat feed motor 3 is started, a rotary encoder (not shown) is provided on the crankshaft of the crank mechanism 11 and the pulse signal output in proportion to the rotation of the crankshaft is counted to count the crankshaft. The position (mesh box position) and the speed of the crankshaft (mesh box speed) are detected.
Set the desired slice thickness, that is, the number of slices, ie, the number of reciprocations of the meat box during the slicer operation, and input it to the sequencer to calculate the time required for the meat box 2 to feed the meat. Since the meat feed motor 3 is started and controlled so that the meat feed can be performed at the timing before returning to the start position by about 1/2, stable slicing work can be performed with a simple operation.
