DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding method and an apparatus for folding a sliced slice of beef, pork or the like into two pieces.

[0002]

2. Description of the Related Art Various methods and apparatuses for folding sliced meat pieces into two have been proposed. For example, in Japanese Patent Application No. 5-287352, a piece of sliced meat supplied from a slicer or the like is forcibly turned up on one side by a bending tool and overlapped on the other side on a conveyor. 2). Japanese Patent Application Laid-Open No. Hei 6-315340 discloses a method in which soft raw meat is straddled by thin fingers, folded in half, and then placed close to a conveyor. The former requires a member for folding and a driving device, so that the structure becomes complicated, and in addition, there is a drawback that a meat piece adheres to the folding tool and the folding posture is disturbed. Further, in the latter case, if the bending line is not substantially at the center position, the bending line may be shifted or slipped off, resulting in instability. For example, it is difficult to obtain a desired bending posture with relatively narrow pork loin.

[0003]

SUMMARY OF THE INVENTION In order to solve these problems, the present invention is to use a simple device to efficiently cut sliced meat pieces cut in a slicer or the like and supplied in an expanded state at an arbitrary bending position. An object of the present invention is to fold well and orderly, and is configured as follows.

[0004]

In other words, according to the method of folding a sliced meat piece according to the present invention, a sliced meat piece thrown in an unfolded state can be freely retracted while a part of the sliced meat piece overflows from one side. The edge of the side on which the sliced meat piece overflows is used as a bending line, and the portion of the sliced meat piece that has overflowed is bent toward the back side of the receiver by inertia force when thrown, and then vertically opposed to the receiver. The method is characterized in that the folded sliced meat pieces are placed on a movable conveyor. Further, the sliced meat piece folding apparatus according to the present invention provides a sliced meat piece having a throwing tool that transports the sliced meat piece at a predetermined speed to the folding apparatus in a spread state, and a driving device that intermittently moves the throwing piece. The device and the sliced meat piece supplied by the supply device are received in a planar manner in a state where a part of the sliced meat piece overflows, and the edge on the side where the received sliced meat piece overflows becomes a bending line of the overflowing portion of the sliced meat piece. It is characterized by comprising a configured receiving device and a driving device for moving the receiving device to the receiving position.

[0005]

According to the present invention having the above structure, the edge of the receiving piece is bent as a bending line by using the inertia force of the portion of the sliced meat piece thrown out by the throwing tool, which protrudes from the receiving piece. Without the need for simple folding tools,
The structure is extremely simple, the finish is beautiful and the bending speed is fast, so efficient work can be performed. In addition, since the sliced meat pieces are received in a flat state with the receiving device in a spread state, and only the overflowed portion is bent at the edge of the receiving device as a bending line, the bending line can be freely selected by appropriately adjusting the receiving position. Can be.

[0006]

Embodiments of the present invention will be specifically described below with reference to the drawings. This sliced meat piece folding apparatus M is capable of cutting the block meat at −2 to 5 ° C. for 2 to 3 minutes.
It is used in combination with the slicing device S for slicing into mm. The slicing apparatus S includes a machine frame 1, and a swing frame 3 holding a cylindrical holder 2 is supported by a shaft 5 provided at an upper portion of the machine frame so as to swing back and forth (left and right directions in FIG. 1). Have been.

Reference numeral 4 denotes a crank device for swinging the swing frame 3, which rotates around a shaft 4a.

The air cylinder 10 is a pressure driving device for the pressing tool 6, and is expanded and contracted to
Moves back and forth. The number of holders 2 attached to one swing frame 3 is two in the illustrated example (see FIG. 2).
Although two slices can be sliced at the same time, only one holder may be attached, or three or more holders 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. Note that the upper left half of the holder 2 is divided into a gutter shape, and the holder 2c is opened to a position 2b indicated by a virtual line with the rotation fulcrum as a fulcrum to facilitate material supply.

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. The blade body 8 substantially contacts the lower end portion of the holder 2 at least at the cut-up portion (Z portion in FIG. 3), and cuts off fibers and the like by a shearing effect with the lower end portion of the holder. Has become.

At the cutting position near the lower end of the holder 2, the blade body 8 is guided while being slidably fitted in a groove provided at the edge 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 comb rods are arranged so as to be slightly inclined forward along the upper surface of the conveyor 21 near the bending guide rod 71 with the open end of the comb rod facing forward. Here, the sliced meat piece 20 is received, and the receiving member 201 is moved by the air cylinder 203 along the traveling direction of the conveyor 21 from the receiving position of the sliced meat piece 20 to the retreat position where the sliced meat piece 20 can be completely removed from the meat piece. The shape of the receiving member 201 does not necessarily have to be a comb shape, but may be a simple flat plate shape.

Reference numeral 201a denotes a scriber made of a flexible thin plate which is suspended from the mounting device 14e of the hitting device and is provided in the widthwise direction of the receiving member 201. It works to remove.

Conveyor belt 21a of the conveyor 21
Below, a push-up device 300 that locally pushes up the conveyor belt 21a toward the receiving tool 201 is provided as a perspective device that brings the conveyor and the receiving tool 201 closer when receiving the folded sliced meat pieces. Arms 303 and 303 are fixed to a rotating shaft 302 supported by rotating metals 301 and 301 provided on a support frame 250, and a cylindrical push-up tool 208 is attached to a distal end thereof. It should be noted that the expansion and contraction of the belt 21a due to the pushing up is absorbed by the tension of a spring (not shown).

On the other hand, the swinging arm 307 protruding from the intermediate portion of the rotation shaft 302 causes the push-up tool 208 to change from the state of the imaginary line in FIG. A cylinder 308 for swinging is provided.
The cylinder 308 has a specification that allows positioning with a brake whose extension amount can be changed, and is configured so that the extension amount can be controlled by a controller. The cylinder 308 is extended, the push-up tool 208 moves upward to push up the conveyor belt 21a, and the interval between the receiving tool 201 and the conveyor belt 21a is changed stepwise according to the overlap amount of the folded sliced meat pieces. I do.

Next, the operation of the block meat slicing apparatus S and the slice meat folding apparatus M will be described. First, the height of the receiving plate 11 of the slicer S is adjusted to a desired thickness of the sliced meat piece, and the block meat 25 is placed in the cylindrical holder 2. When the driving means such as the cylinders and the motors are operated in this state, the block meat 25 is cut thinly in order from the lower end, and the sliced meat piece 20 is obtained. The operations of the cylinder, the motor, and the like are controlled by a control device (not shown).

The cutting is specifically 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 against the outer peripheral portion of the block meat 25 is relaxed. Then, the block meat 25 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. 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, the motor 9
The cutting is performed by the band-shaped blade 8 circulating. At this time, the pieces of meat hanging by cutting
Are pierced by the projections 26,... Of the transport band 13a with projections of the receiving device 13, and are separated downward as the transport band moves. For this reason, the attachment of the meat pieces to the blade body 8 and the like is prevented.
In addition, since the blade body 8 relatively moves along the lower end surface of the holder 2 while almost in contact with the lower end surface of the side wall, no deformation or escape of the meat occurs at the cut portion. Further, in the cut-up portion (Z), the blade body 8 substantially contacts the lower end portion of the holder (particularly, the inner side edge portion) and is cut off by the scissors effect. We are separated well.

When the holder 2 is sufficiently advanced and the cutting is completed, the holder 2 retreats again, the pressing tool 6 is loosened, and the block meat 25 is fed out onto the receiving plate 11 by the same size. The cut sliced meat pieces 20 are taken out by the transporting band 13a of the receiving device 13, and are transported to the upper portion of the hitting device 14 and stop there.
4 is operated and the hitting rod 14a is turned into the projection 2 of the transport belt with the projection.
The sliced meat pieces 20 escape from the space C provided at the six intervals, and the sliced meat pieces 20
01 and the bending guide rod 71 (FIGS. 9 and 13).
reference). At this time, the adjustment handles 85 and 80a are operated and received so that the desired bending position matches the position on the bending guide rod 71. A part of the sliced meat piece 20 thrown vigorously is received by the comb rod of the receiving tool 201 in a planar shape, but a part of the sliced meat piece 20 overflowing from the bending guide rod 71 is folded by the guide rod 71,
In the case of meat that is bent to the back side of the receiving device 201 with the struck force and is soft and easily adheres, the receiving device 201
And reaches the back side of the sliced meat piece 20 placed on the front side.

Next, the conveyor belt 21 is pushed up by the push-up device 300 until it comes into contact with the lower surface of the folded sliced meat piece 20 (A direction), but at the same time, the belt 21 is driven in reverse so as to move backward (B direction). By doing so, the bending of the bent portion of the sliced meat 20 may be promoted (see FIGS. 10 and 14).

In this case, as shown in FIG.
The amount of extension of the air cylinder 308 of the push-up device is changed so that the approach amount (s1 to s4) with the conveyor belt 21 is changed stepwise by subtracting the thickness of the folded sliced meat piece group Q superimposed on 1 in advance. Control. In addition, conveyor 2
One side may be fixed so that the side of the folding device such as the receiving member 201 and the bending guide bar 71 is moved closer to the conveyor side from the slice meat receiving position.

Next, as shown in FIG.
The holding rod 211 retracted to the side end of the transfer surface of the air cylinder 2 and stored in the cylinder 204a and in the standby state is
09 to advance on the meat piece 20 (FIG. 14), and then, as shown in FIGS. 10 and 15, the rotary actuator 219 is operated to rotate the sector gear 2 fixed to the drive shaft.
23 with the ring gear 218 engaged with the cylinder 204a.
Is rotated together with the air cylinder 209 in the direction of the arrow, and the pressing bar 211 presses the surface of the sliced meat piece 20 over the entire width.

Subsequently, as shown in FIGS. 11 and 15, the air cylinder 203 is operated to retreat the receiving member 201 along the traveling direction of the conveyor 21 to a retreat position where the receiving member 201 can be completely removed from the sliced meat piece 20.

Next, the air cylinder 204 is operated to pull out the bending guide rod 71 from the folded sliced meat and store it in the cylinder 204a (FIG. 16). Next, the rotary actuator 219 is turned over to
1 to the standby position (FIGS. 11 and 17), and the cylinder 20
9 is actuated and drawn into the cylinder 204a.

After folding the sliced meat pieces in this manner, the conveyor belt 21 moves by a predetermined amount, and the folded meat pieces 20 are sent forward by one pitch. Then, the air cylinder 308 of the lifting device 300
To return the conveyor belt 21 to the original position (FIG. 11).

With the above, a series of folding operations is completed.
The receiving member 201 and the bending guide bar 71 are projected onto the conveyor 21 in preparation for the next operation, and are brought into a standby state.

The same operation is repeated thereafter, and as shown in FIG. 12, a so-called scale-like sliced meat piece 20 is sequentially superimposed with the bent portion (pork spinach or the like having a large fat side) positioned on the front side. Is carried on the conveyor.
