Abstract

PROBLEM TO BE SOLVED: To slice even soft raw meat without causing the escape thereof from the inner surface of a cylindrical holder by cutting block meat in the condition where the block meat is housed within the holder and relatively moved for a cutter body, with a part of the surrounding wall of the holder moved to press and secure the outer part of the block meat with other surrounding walls of the holder. SOLUTION: Block meat 25 drops to a receiver plate 11, due to the dead load thereof, and is positioned with the receiver plate 11. Thereafter, a presser 6 is tightened so as to leave almost no gap between the other surrounding walls of a holder 2 and the presser 6. At the same time, a meat lump is somewhat solidified and the rigidity of the meat itself increases. In this state, when the holder 2 advances, the block meat 25 is cut with a strip type cutter body 8 circulating on the operation of a motor.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a block meat slicing device capable of slicing block meat such as beef and pork in a raw state without freezing.

[0002]

2. Description of the Related Art Various devices have been developed for slicing block meat such as pork (for example, Japanese Utility Model Application Laid-Open No. 56-160793 and Japanese Utility Model Application Laid-Open No. 56-160794).
JP-A-50-69271, JP-A-4-42152
And JP-A-6-246682. In addition to these, various other slicing apparatuses have been put to practical use. Conventionally, when slicing block meat using this kind of slicing apparatus, the block meat is sliced using a rotating round blade in a frozen and hard state. Was common. This is because when the block meat is not frozen, that is, in the state of raw meat (more than minus 1 degree C), the meat itself is too soft and deforms during cutting and escapes, and uniform cutting is not performed, and moreover, This is because there is a problem that the contained fibers cannot be cut off well. In addition, there is a problem that even when the blade is cut, the cut thin wall sticks to the blade body or scatters.

[0003] This is a device for cutting meat pieces for shabu-shabu.
There is also a type in which the outer surface of a raw meat mass is nipped from the left and right and pressed by a roller from above to slice it. With such a device,
Soft raw meat can be sliced for the time being, but there is a problem in that the yield is low because of the large amount of scattered meat pieces and the large amount of waste meat generated.

[0004] Therefore, when slicing block meat, the slices were sliced in a frozen and hard state as described above. However, when slicing the frozen meat, when the temperature became close to normal temperature, blood-colored drip oozed out. Since the tray is soiled, there is a problem that the appearance is poor, the commercial value is reduced, and the taste is also changed. Also, the need to freeze and solidify to slice block meat requires extra labor, equipment and time,
There is also the problem of being uneconomical. For this reason, there has been a strong demand for an apparatus that can efficiently slice block meat in the state of soft raw meat that is not frozen.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention provides a slicing method and apparatus capable of slicing block meat in a raw meat state uniformly and efficiently and capable of slicing meat fibers and the like well. The task is to do.

[0006]

In order to solve the above problems, the present invention employs the following configurations. That is, the method for thinly slicing block meat according to the present invention is such that the block meat is inserted into a vertically-oriented cylindrical block meat holder so that the lower end portion projects from the holder, and the block meat is blocked by a pressing tool that moves in the holder. The meat is held in a state of being pressed and closely attached to the curved inner wall surface of the holder, and the band-shaped blade provided at the lower end of the holder is attached to the holder so that the meat comes into contact with the lower end of the holder at least at the cut-up portion. The feature is that the protruding portion of the block meat is cut by moving the block meat relatively.

The block meat slicing device according to the present invention is provided with a cylindrical holder for accommodating and holding the block meat and reciprocating in a predetermined range back and forth, and facing the opening end of the holder. A blade body that thinly cuts the block meat end protruding from the opening end of the holder by the movement of the holder, and the blade is provided so as to contact the opening end of the holder at least at the cut-up portion. A part of the peripheral wall of the holder is movable inward and outward, and is configured as a pressing tool that moves inward during cutting and presses and fixes the outer peripheral surface of the block meat between the wall surface and another wall surface. Is characterized by. In this case, the holder is configured to swing back and forth around a fulcrum provided at the top,
It is preferable to dispose the blade body so as to face the lower end opening.

The block meat housed in the cylindrical holder is
Since it is pressed from the outer peripheral portion at the time of cutting and is held so as not to escape during cutting, even if the raw meat is not frozen and solidified, escape due to deformation does not occur and good slicing can be performed. The pressing surface of the pressing member that abuts the outer peripheral surface of the block is formed as a concave surface toward the outer peripheral surface of the block so that a force for pressing the outer peripheral portion of the block meat having an irregular cross section toward the central portion acts. It is preferable to keep it.

Further, the holder is provided so as to swing back and forth around a fulcrum provided at the upper part, and the lower end outline is formed in a downwardly convex arc shape, and the blade body follows this curve. When the block meat is relatively moved, the block meat is firmly held along the cutting line up to the vicinity of the cutting line, so that cutting with a uniform thickness can be performed.

When one cutting is completed, it is necessary to send the block meat to the opening side for the next cutting, and to project it from the holder opening by a predetermined amount (corresponding to the thickness of the sliced piece). In order to do so, a receiving plate is provided near the opening of the holder at a predetermined interval, and when the cutting is completed, the pressing tool is loosened to move the block meat, and the block is brought into contact with the receiving plate for positioning. It may be fixed again with the pressing tool. When cutting is performed at the lower end of the holder, the backing plate may be placed at a position directly below the holder at a position away from the blade body, and the block meat may be dropped onto the backing plate by its own weight. .

Further, it is preferable to provide, immediately below the blade body, a carrier body with a protrusion that pierces and holds a slice piece separated from the block meat and moves it downward.
If such a carrier is provided, the sliced piece to be separated is pulled by the carrier in the direction in which the cut opens, so that the separation is performed well, and the edge of the sliced piece is cut up at the cut-up portion. It does not adhere to the blade and other parts, and its position is not disturbed. Therefore, the thin slice pieces can be taken out without any disturbance in the expanded state.

This block thinning device S is provided with a machine frame 1, and a swing frame 3 holding a cylindrical holder 2 swings back and forth (left and right directions in FIG. 1) by a shaft 5 provided at an upper portion of the machine frame. It is freely supported.

Numeral 4 is a crank device for oscillating the oscillating frame 3, which rotates about a shaft 4a,
The swing frame 3 and the holder 2 swing integrally within a predetermined range.

As shown in FIG. 3 or 4, the holder 2 is formed as a vertically long tubular body having a concave wall surface 2a on the inner side. And the front surface 2
b is formed as a slightly thick flat surface, and the air cylinder 10 is attached to the outer surface portion thereof. Also, the plane 2b
A pressing tool 6 having a concave surface 6a in plan view is provided on the inner side of the pressing tool 6 toward the center of the holder 2. The rod of the air cylinder 10 is attached to the central portion of the pressing tool 6, and the slide bearings 2 are provided on both left and right sides.
Guide rods 24, 24 supported by c, 2c are attached.

The air cylinder 10 is a pressure drive device for the pressing tool 6, and by expanding and contracting the pressing tool 6, the pressing tool 6 is driven.
Moves back and forth. In addition, the concave surface 6a of the pressing tool has a triangular shape in a plan view in the example of FIG. 3 and is formed in an arc shape in the embodiment of FIG. 4, but the shape of the concave surface depends on the size of the holder and the type of block meat. The optimum one can be selected according to the above, that is, one that can be tightened well from the outer peripheral portion so that the block meat does not escape during cutting. Further, the number of holders 2 attached to one swing frame 3 is two in the illustrated example (see FIG. 2), and two slices can be sliced at the same time. Only three or more may be attached. Since this slicing apparatus uses a band-shaped blade as described later, a plurality of holders can be arranged side by side and cut simultaneously.

The lower ends of the side walls 2d, 2d of the holder 2 are formed in a downwardly convex arcuate shape in a side view (see FIG. 7). The radius of curvature of this arc-shaped curve is close to the swing radius of the holder 2. A receiving plate 11 having an upwardly concave curved surface is provided at a predetermined interval t between the holder and the lower end of the holder so as to follow the curve of the lower end of the holder. By adjusting the height of the receiving plate 11 (the distance from the lower end of the holder), the thickness of the sliced piece to be cut can be adjusted.

The receiving plate 11 is attached to the thickness adjusting frame 17. The frame 17 is attached via swing links 18 to a support frame 27 mounted on rails 1a of the machine frame 1 via rollers 27a,. The support frame 27 is fixed to a predetermined position of the machine frame 1 by a removable locking device (fixing pin P in the illustrated example). However, by removing this locking device, the support frame is placed outside the machine frame 1 (see FIG. 1). Since it can be pulled out on the rail in the direction of arrow Y), it is convenient for cleaning and maintenance.

Reference numeral 19 is a motor as a thickness adjusting means, and as shown in FIG. 8, an adjusting screw 29 is attached to its rotary shaft. A female screw member 19b slidably engaged with a motor frame 19a, which is rotatably supported on a supporting frame 27 by a rotating pin 28, is screwed to the adjusting screw 29. The female screw member 19b is attached to the frame 17 by the shaft 1
7a and the horizontal bar 17b are connected, so that when the motor 19 is actuated, the female screw member screwed into the adjusting screw 29 moves in the axial direction of the adjusting screw, and the solid line and the chain line in FIG. As shown by, the receiving plate 11 and the adjusting frame 1
7 moves diagonally up and down. Therefore, the gap between the receiving plate 11 and the holder 2 can be adjusted.

A blade 8 for cutting is provided on the front side of the holder 2. The blade body 8 is a band-shaped blade body joined in a ring shape, and as shown in FIG. 2, a drive drum 22 attached to a rotating shaft of a drive motor 9 provided on one side of the machine frame 1. And a driven drum 23 provided on the opposite side of the machine frame, and circulates in a predetermined direction at a predetermined speed by the rotation of the driving motor 9. A sharp edge having a wedge-shaped cross section is formed on one side edge of the band-shaped blade 8 over the entire circumference. When the holder 2 passes through the position of the blade 8 in its forward swinging stroke, the block meat projecting downward from the holder is sliced by the blade. In addition, the blade body 8
At least in the cut-up portion (the Z portion in FIG. 1), the fibers and the like are cut off substantially by the shearing effect between the lower end of the holder 2 and the lower end of the holder 2. The blade body 8 may be brought into contact with the lower end portion of the holder 2 from the start of cutting to the cutting up, but in that case, there is a problem that the blade body is easily worn.

At the cutting position near the lower end of the holder 2, the blade 8 is guided while being slidably fitted in the groove 12a of the blade holding plate 12. For this reason, even if a thin band-shaped blade is used, the blade 8 can be cut accurately without swinging. The upper surface of the blade holding plate 12 is formed as a concave curved surface having a radius of curvature similar to the swing radius of the holder 2 as in the case of the receiving plate. Swing along its upper surface.

On the lower side of the blade body 8, a plurality of transport belts 13a with protrusions, each having a plurality of needle-like protrusions 26, ...
Is provided. .. of the receiving device 13 are provided in parallel with each other at equal intervals, and are wound around upper and lower rollers 30 and 31, respectively, as shown in FIG. Reference numeral 33 is a receiving frame to which the rollers 30 and 31 are attached, and is fixed to the thickness adjusting frame 17.
Therefore, the receiving frame 33 moves up and down integrally with the thickness adjusting frame 17. A driving device mounting member 15a is fixed to the support frame 27, and a driving device for a receiving device (motor in the illustrated example) 1 is attached to this.
5 is attached. A belt (or chain) is stretched between a pulley (or sprocket) 15b of the motor 15 and a (pulley or sprocket) 14e attached to the shaft end of a roller shaft 14c to which the roller 31 is fixed. By the rotation of the motor 15, the plurality of transport belts 13a with protrusions simultaneously circulate in the direction of the arrow. The transport belts 13a,... Are transporters for transporting the slice pieces downward, but instead of such transport belts, transporters such as rotary drums having projections planted on the outer periphery may be used.

Conveyor belt 13 with protrusions of the receiving device 13
A detaching device (striking device) 14 is provided inside a,. As shown in FIGS. 2 and 7, the flicking device 14 includes a plurality of flicking rods 14a, ... Swinging inward and outward through the gap between the transport belts 13a ,.
The base of the hammer rod is fixed to a fixture 14b loosely fitted to the roller shaft 14c, and has a comb-tooth shape. The attachment 14b is integrally provided with an arm 14d that protrudes in the radial direction, and a connector 15e attached to the rod end of the air cylinder 16 is attached to the arm 14d with a pin.
The air cylinder 16 is a means for driving a punching device, and the expansion and contraction thereof causes the fixture 14b to rotate in the forward and reverse directions, so that the punching rods 14a ... Swings in and out.

Below the receiving device 13, a transfer device 21 for taking out is provided. As the transfer device 21, a circulating transfer type transfer device such as a normal belt conveyor can be used.

When the block meat thinning device S is used, the height of the receiving plate 11 is adjusted to a desired sliced meat piece thickness, and the block meat 25 is placed in the cylindrical holder 2.
Insert When the driving means such as the cylinders and motors are operated in this state, the block meat 25 is thinly cut in order from the lower end thereof, and the sliced meat piece 20 is obtained. The operations of the cylinder, the motor, etc. are controlled by a controller (not shown).

Specifically, the above cutting is performed in the following procedure. First, with the holder 2 retracted from the blade body 8, the air cylinder 10 contracts, and the pressing of the pressing tool 6 on the outer peripheral portion of the block meat is relaxed. Then, block meat 2
5 falls on the receiving plate 11 by its own weight, and is positioned by the receiving plate. Thereafter, the cylinder 10 extends again, and the pressing tool 6 presses the outer peripheral surface of the block meat 25. This allows the block meat 25 to move between the other wall surface of the holder and the pressing tool 6.
And there is almost no gap between them, and the meat chunk is somewhat solidified and the rigidity of the meat itself is improved. Block meat 25
Is easy to deform because it is in a soft raw meat state.
It can be tightened with almost no gap between the pressure member 6 and the pressing member 6.

When the holder advances in this state, as shown in FIG. 5, the cutting is performed by the belt-shaped blade body 8 which is circulatingly run by the motor 9. At this time, the meat pieces hanging down due to cutting are the protrusions 2 of the transport belt 13a with protrusions.
Are pierced by 6, and are separated downward as the transport bodies 13a ,. For this reason, adhesion of the meat piece to the blade body 8 and the like is prevented, and the blade body 8 moves relatively along the lower end surface of the holder 2 in a state of being almost in contact with the lower end surface as shown in FIG. Therefore, the meat is not deformed or escaped at the cut portion. Also, in the rounded-up part (Z),
The blade body 8 substantially comes into contact with the lower end portion of the holder (in particular, the inner side edge portion) and the cutting is performed by the scissors effect, so that the meat is well separated even if there are fibers or fat. In addition,
As shown in the figure, with respect to the lower end surface of the holder 2,
Since the blade body 8 escapes by the angle α, it does not come into contact with a new cut surface of the block meat, and discoloration of the meat due to friction does not occur.

When the holder 2 is sufficiently advanced and the cutting is completed, the holder 2 is retracted again, the pressing tool 6 is loosened, and the block meat 25 is extended to the receiving plate 11 by the same size. The cut sliced meat pieces 20 are conveyed to the upper portion of the take-out device 21 by the conveyor belts 13a,. Then, the tapping device 14 operates and the transport belt 1
The knocking rods 14a,... Projecting from the intervals 3a,. The sliced meat pieces 20 that have been knocked down are sequentially transferred to a transport device 21.
Is carried out to a predetermined position.

This block meat slicing device S accommodates the block meat in a cylindrical holder, moves a part of the peripheral wall of the holder, and presses the outer peripheral portion of the block meat against another wall surface. Since it is sliced in the state, even if the raw meat is soft, there is no escape during cutting and it can be sliced well.
In the illustrated example, a strip-shaped blade is used as the blade, but a disc-shaped rotary blade can be used by changing the design.

Further, in the illustrated example, the block meat is sent by dropping due to its own weight after completion of one cutting,
A belt with a vertical protrusion or the like may be provided along the inner wall of the holder to forcibly feed the belt downward. Furthermore, when cutting with a blade having a linear blade edge as in the illustrated example, burrs and the like may occur if the outline of the cut-up portion is a straight line parallel to the ridgeline of the blade edge, As shown in FIG. 9, it is preferable to cut in a direction in which the cutting edge ridge L is inclined (not parallel) with respect to the outline C of the cut-up portion. The cutout may be cut with a straight blade while holding the block meat so that the outline of the cut-up portion is not a straight line but, for example, a curve that is convex in a plan view.
In the holder shown in the figure, the inner wall surface of the cut-up portion is a concave curved surface in plan view, so that the block meat is pressed and held in a convex shape in plan view at this portion, so that the cut-up portion is clean.

[0030]

As is apparent from the above description, according to the present invention, the block meat is housed in the cylindrical holder, and a part of the peripheral wall of the holder is moved so that the outer peripheral portion of the block meat is changed. Since it is pressed against and fixed to the wall surface of the blade and moved relative to the blade body for cutting, even soft meat can be sliced well without escaping from the inner surface of the holder.
