Description

The present invention relates to slicers.

As a conventional slicer, for example, bulk food such as raw meat, processed meat, cheese, etc., is sequentially thinly cut into food pieces, and a plurality of these food pieces are arranged so that some of them overlap each other to form an aggregate of food pieces. there is something to do
By forming a plurality of pieces of food into an aggregate in this manner, it is possible to easily store the pieces in a container, thereby improving work efficiency in a food processing factory.
In addition, it becomes easy to take out the pieces of food while separating them from the container, which improves convenience in cooking.
When the food is raw meat, the thinly sliced raw meat is usually folded into 5 to 10 pieces and placed side by side to form an aggregate of meat pieces, and the aggregate is placed in a tray. Then, the total weight, unit price, etc. are displayed and shipped as a product.

As such a slicer, in Patent Document 1, a lump of raw meat is vertically cut from its tip portion to form a plurality of thin pieces one by one, and the thin pieces are folded at their intermediate portions. A technique is disclosed in which pieces are arranged side by side so as to partially overlap each other to form an aggregate.
Further, Patent Literature 2 discloses a technique of conveying an aggregate formed of a plurality of thin pieces at predetermined intervals and storing them in a tray.
Patent Literature 3 discloses a technique for automatically changing the number of meat pieces to be arranged in parallel and the cut thickness of the meat pieces so that the weight of the aggregate of meat pieces approaches a set weight.

Japanese Patent No. 4264518 Japanese Patent No. 5875156 Japanese Patent No. 4942696

However, bulk food such as raw meat does not have a uniform cross-sectional shape from the tip to the rear end, and the cross-sectional shape changes irregularly. The size (length) and weight of food pieces are not uniform.
For this reason, when the same number of food pieces are stacked at the same pitch, the total length and weight of the aggregate formed by this will vary.
When the weight of each group varies in this way, it becomes difficult to align the displayed weight range and the accompanying displayed price range of the product, so manual adjustments are required and work efficiency is reduced. problems arise.

In addition, when automatically changing the number of food pieces to be arranged side by side and the cutting thickness using the technology disclosed in Patent Document 3, it is possible to reduce the variation in the weight of each food piece assembly. Even if it could be done, the total length of the aggregate cannot be aligned because the pitch of the parallel arrangement of the food pieces is not automatically adjusted.
Due to this variation in total length, for example, the total length of the aggregate becomes too large, and when it is stored in a container such as a tray, it protrudes from the container, or conversely, the total length of the aggregate becomes too small, creating a gap in the container. In addition, it is necessary to rearrange the pieces of food manually, which causes problems such as a decrease in work efficiency.
In addition, since the thickness of the pieces of food stored in the same container such as a tray varies, a problem may arise that the product value is lowered.

It communicates with the channel 326 in a switchable manner.

The buffer/speed control circuit 325 includes a pilot check valve 327 whose check direction is switched bidirectionally, a check valve 328, a manually operated first variable throttle valve 329, an air tank 330, and a two-position switching valve 331. , a first atmosphere release device 332 for buffering, a manually operated second variable throttle valve 333 for adjusting the amount of air sent to this first atmosphere release device 332, and a second atmosphere release device 334 for speed adjustment. and a manually operated third variable throttle valve 335 for adjusting the amount of air sent to the second atmosphere release device 334 .
Also, the third flow path 336 branched from the inside of the pilot check valve 327 communicates with the contraction side port of the second air cylinder 241 .

One end of the fifth flow path 338 communicates with the middle portion of the fourth flow path 337 communicating with the second flow path 326 in the buffer/speed adjustment circuit 325 , and the other end of the fifth flow path 338 connects to the air tank 330 . communicate.
A check valve 328 and a first variable throttle valve 329 are communicated in parallel in the middle of the fifth flow path 338 .
One side of the pilot check valve 327 communicates with the intermediate portion of the fourth flow path 337 , and the other side of the fourth flow path 337 communicates with the IN port of the two-position switching valve 331 .
The OUT port of the two-position switching valve 331 is selectively communicated with the first atmosphere opening device 332 and the second atmosphere opening device 334 by the switching operation of the two-position switching valve 331 .
The switching operation of the two-position switching valve 331 is performed in conjunction with the remaining amount of air in the air tank 330 .

A second variable throttle valve 333 is connected between the OUT port of the two-position switching valve 331 and the first atmosphere release device 332 , and a third throttle valve is connected between the OUT port of the two-position switching valve 331 and the second atmosphere release device 334 . A variable throttle valve 335 is communicated.
Thus, in a state in which the electromagnetic switching valve 323 is switched to the one-side position shown in FIG. 337 and pilot check valve 327 without load, flows through the third flow path 336 into the shortening side port of the second air cylinder 241, and the piston 244 of the second air cylinder 241 shortens at high speed.

As a result, the receiving plate 202 slides left and right inward, and the distance between the opposite ends of the left and right receiving plates 202, 202 becomes the minimum distance P1.
Part of the air that has flowed into the fourth flow path 337 passes through the check valve 328 from the fifth flow path 338 and flows into the air tank 330, where pressure is accumulated in the air tank 330. , the two-position switching valve 331 is held at the position shown in FIG. 39 against the resilient force of the return spring 331S.
In this state, air from the fourth flow path 337 to the two-position switching valve 331 is shut off by the pilot check valve 327 .

Then, when the electromagnetic switching valve 323 is switched to the other side position by the output from the controller to the switching solenoid 323S, the air flowing in from the IN port 321 flows from the first flow path 324 to the extension side port of the second air cylinder 241. The air flows in and the piston 244 of the second air cylinder 241 begins a high speed extension operation.
As a result, the receiving plate 202 starts to slide laterally outward.
During this sliding, the air in the contraction side chamber of the second air cylinder 241 is discharged to the third flow path 336 by the movement of the piston 244 to the extension side, and is discharged from the pilot check valve 327 to the opening side chamber. It passes through the 4-channel 337 and reaches the IN port of the 2-position switching valve 331 .

The air that has reached the IN port of the two-position switching valve 331 flows out from the OUT port of the two-position switching valve 331, is restricted in flow rate by the third variable throttle valve 335, and is discharged to the outside from the second atmosphere opening device 334. be done.

Controlled by the speed, the sliding speed of the receiving plate 202 to the left and right outward direction is kept constant.
The extension speed of the piston 244 of the second air cylinder 241 , that is, the sliding speed of the receiving plate 202 can be changed by manually adjusting the third variable throttle valve 335 .
In addition, while the piston 244 of the second air cylinder 241 is expanding at high speed, the air accumulated in the air tank 330 flows out to the fifth flow path 338, and the first variable throttle valve 329 It is gradually discharged to the OUT port 322 through the second flow path 326 and the electromagnetic switching valve 323 while the flow rate is restricted.

Then, when the air accumulated in the air tank 330 is exhausted, the two-position switching valve 331 is switched by the resilient force of the return spring 331S.
As a result, the air that has passed through the fourth flow path 337 on the open side from the pilot check valve 327 is discharged to the outside from the first atmosphere opening device 332 while the flow rate is restricted by the second variable throttle valve 333 . Become.
This state appears just before the piston 244 of the second air cylinder 241 reaches the stroke end in the extension direction, and the extension speed of the piston 244 is much lower than the speed before this.
As a result, the impact when the piston 244 reaches the stroke end in the extension direction is buffered, and the impact and noise caused by the sudden stop of the receiving plate 202 can be mitigated.

In this state, the tips of the front and rear fourth index plungers 297, 297 are fitted into the holes formed in the peripheral surface of the cylindrical frame 252 to prevent the round bar 298 from falling out of the openings of the hook members 296, 296. do.
As a result, the other end of the transfer belt 295 is attached to the cylindrical frame 252 and fixed at a fixed point.

As described above, the lower surface of the upper winding area of the transfer belt 295 is slidably supported on the receiving surface 201 formed on the upper surface of the receiving plate 202 .
A groove is formed in the longitudinal direction on the peripheral surface of the cylindrical frame 252, and a round bar 298 inserted through the other end of the transfer belt 295 is inserted into the groove. It is good also as composition which prevents omission.
The operation of removing the transfer belt 295 is performed in the reverse order of the above.

(Operation of main part of article moving device)
Hereinafter, the first position PS1, the second position PS2, and the third position PS3 will be described with reference to the position of the inner edge of the receiving surface 201 or receiving plate 202 that supports the transfer belt 295. FIG.

(first position)
That is, with the inner end portions of the receiving surfaces 201 and 202 positioned at the first position PS1, the receiving surfaces 201 and 202 cover the entire upper side of the tray G1 conveyed therebelow. (This state refers to a state in which the receiving surface 201 or receiving plate 202 overlaps the entire area of the tray G1 in plan view.)
With the inner ends of the left and right receiving surfaces 201, 201 or the left and right receiving plates 202, 202 positioned at the first positions PS1, PS1, the pieces of meat m or a set of pieces of meat m are conveyed in two rows. Each of the bodies M is fed onto the left and right transfer belts 295, 295 from the transfer end of the reciprocating conveyor 95. As shown in FIG.

(Movement from first position to second position)
Further, even when the inner ends of the left and right receiving surfaces 201, 201 or receiving plates 202, 202 are moved to the second positions PS2, PS2 slightly shifted outward from the first positions PS1, PS1, this The receiving surfaces 201, 201 or the receiving plates 202, 202 substantially cover the upper sides of the two adjacent trays G1, G1 conveyed therebelow. (This state includes a state in which a small portion of the end portions of the trays G1, G1 is not covered and exposed in a plan view.)
By moving the left and right receiving surfaces 201, 201 or the inner ends of the left and right receiving plates 202, 202 from the first positions PS1, PS1 to the second positions PS2, PS2, the left and right transfer belts are moved. The left and right intervals of the pieces of meat m or aggregates M of pieces of meat m on 295, 295 are enlarged, and positioned so that they can be placed on the two adjacent trays G1, G1 standing by below.

The adjustment amount of the left-right spacing of the meat pieces m or aggregates M on the left and right transfer belts 295, 295 is the left-right spacing of the two conveying passages 20, 20 of the lump meat conveying device 9 in the cutting section 4. and the conveying pitch of a large number of trays G1 conveyed by the tray conveying device 305. FIG.
That is, since the conveying pitch of the many trays G1 conveyed by the tray conveying device 305 is determined by the lateral width of the tray G1 itself, there is a limit to reducing this conveying pitch.

On the other hand, the horizontal interval between the two rows of meat pieces m or aggregates M that are cut out and conveyed by the cutting section 4 is determined by the horizontal interval between the two conveying passages 20 , 20 of the lump meat conveying device 9 .
The center-to-center distance between the two adjacent trays G1, G1 (standard food trays generally used) conveyed at the above-mentioned conveying pitch is the two conveying passages 20, 20 center-to-center distance (wider in the left-right direction).
Therefore, in order to place two rows of meat pieces m or aggregates M on two adjacent trays G1, G1, two rows of meat pieces m or aggregates M must be conveyed at narrow intervals in two rows to eliminate the above-described difference between the two centers. It is necessary to widen the left-right direction interval of the meat piece m or aggregate M that has come.
Therefore, as described above, the left and right receiving surfaces 201, 201 or the inner ends of the left and right receiving plates 202, 202 are moved from the first positions PS1, PS1 to the second positions PS2, PS2. The left-right interval of the pieces of meat m or aggregates M of pieces of meat m on the transfer belts 295, 295 is widened so that the meat pieces m are positioned so that they can be placed on the two adjacent trays G1, G1 standing by below. be.

(Movement from second position to third position)
When the inner ends of the receiving surface 201 or the receiving plate 202 move outwardly from the second position PS2 and are positioned at the third position P3, the receiving surface 201 or the receiving plate 202 move downward. The upper side of the conveyed tray G1 is retracted, and the entire upper side of the tray G1 is released.
When the left and right receiving surfaces 201, 201 or the left and right receiving plates 202, 202 move to the outer third positions PS3, PS3, the left and right transfer belts 295, 295 295 move inwardly with respect to the left and right receiving plates 202 , 202 .
As a result, the pieces of meat m or aggregates M on the left and right transfer belts 295, 295 are lowered and placed on the two trays G1, G1, respectively, without changing their positions in the left and right direction.

(Explanation of operation of receiving plate and transfer belt)
FIG. 24 shows the operating state of each of the moving units after the moving units 200R and 200L on the left and right sides have moved outward (to move away from each other) due to the shortening operation of the first air cylinders 225 and 225. It is a front view for explaining.
That is, in FIG. 24, in the state of (a), the left and right first air cylinders 225, 225 are shortened, and the receiving surfaces 201, 201 supporting the transfer belts 295, 295 or the inner ends of the receiving plates 202, 202 are retracted. has moved from the first positions PS1, PS1 covering the entire upper side of the two trays G1, G1 conveyed therebelow to the second positions PS2, PS2 deviated outwardly by a small distance. .
As a result, the distance between the inner ends of the left and right receiving plates 202, 202 is expanded from P1 shown in FIG. 16 to P2 shown in FIG.
Even in this state, the receiving surfaces 201, 201 or receiving plates 202, 202 supporting the transfer belts 295, 295 substantially cover the upper sides of the two trays G1, G1 conveyed therebelow.

In addition, the left and right second air cylinders 241, 241 are shortened, and the left and right receiving plates 202, 202 integrated with the tip portions of the pistons 244, 244 of the second air cylinders 241, 241 are used for the article moving device 200. moving inward.
When the second air cylinder 241 is extended from this state, as shown in FIG. 3 Move to position PS3.
Together with the receiving plate 202, the axis 234 of the first timing pulley 233 and the axis 236 of the second timing pulley 235, which are integrated with the tip of the piston 244 of the second air cylinder 241, move outward by the full stroke. do.

A portion of the upper winding region of the timing belt 237 wound around the first timing pulley 233 and the second timing pulley 235 is held at a fixed position by a fixing member 238 .
Therefore, when the shaft center 234 of the first timing pulley 233 and the shaft center 236 of the second timing pulley 235 move outward, the two timing pulleys 233 and 235 rotate in the same direction, and the timing belt 237 rotates. The lower winding area of moves outward.
As a result, the first slider 246 attached to the lower winding area of the timing belt 237 moves outward together with the traction plate 250 , and the traction plate 250 pulls one end of the transfer belt 295 . is pulled outward.

At this time, since the transfer belt 295 is folded back from the upper surface of the receiving plate 202 at the inner edge of the receiving plate 202 and laid along the lower surface of the receiving plate 202, the transfer belt 295 does not become slack. In order to move the inner end of plate 202 outwardly, the traction plate 250 must be moved twice as far outwardly as the backing plate 202 is moved outwardly.
That is, as shown in the state change from (a) to (b) in FIG. 24, a virtual fixed point CP1 is set at a portion of the transfer belt 295 on the receiving plate 202 ((a) in FIG. 24). It is assumed that the inner end of the receiving plate 202 supporting the loading belt 295 moves to the imaginary fixed point CP1 (FIG. 24(b)).

At this time, the outer end of the pulling plate 250 moves the first moving distance S until the inner end of the receiving surface 201 or receiving plate 202 supporting the transfer belt 295 reaches the imaginary fixed point CP1. It is necessary to move a second movement distance T, which is twice S.
For this purpose, a mechanism consisting of the timing belt 237 and the two timing pulleys 233 and 235 described above is provided. ), the outward moving speed of the traction plate 250 is doubled.
As a result, when the receiving surface 201 or receiving plate 202 supporting the transfer belt 295 moves from the second position PS2 to the third position PS3, the transfer belt 295 moves in the direction opposite to the moving direction of the receiving surface 201. move in the same direction with the same speed.

In FIG. 24, (a) is a closed state in which the receiving plate 202 or the receiving surface 201 supporting the transfer belt 295 enters above the tray G1 and substantially covers the upper part of the tray G1, and (b) is the receiving plate. 202 (receiving surface 201) is retracted from above the tray G1 to open the upper side of the tray G1.
In the state of (b), the meat piece m or aggregate M on the transfer belt 295 is separated from the surface of the transfer belt 295 by the folding movement of the transfer belt 295 at the inner end of the receiving plate 202, and the tray G1 is removed. It falls inside and is contained.
That is, the piece of meat m or aggregate M that has been placed on the receiving surface 201 from the conveying end portion of the conveying action portion 5R on the downstream side in the conveying direction remains at the position in the left-right direction and the front-rear direction, It is lowered, placed and stored in the tray G1 directly below.

16 and 17 show a state in which the receiving surface 201 or receiving plate 202 supporting the transfer belt 295 is positioned at the first position PS1 covering the entire upper side of the tray G1, and FIGS. It shows a state in which the receiving surface 201 or receiving plate 202 has moved outward to a second position PS2 (a second position deviated from the first position by a predetermined distance) that substantially covers the upper side of the tray G1.
20 and 21, the receiving surface 201 or the receiving plate 202 supporting the transfer belt 295 reaches the third position (the third position where the article on the transfer belt 295 is unloaded) PS3 where the upper side of the tray G1 is opened. It shows the state of moving outward.
Incidentally, as described above, the receiving surface 201 or the receiving plate 202 is arranged below the front-rear movement range of the transport end portion of the transport action portion 5R on the downstream side in the transport direction.

(Tray transport device)
25-27 show a tray transporter 305 with a container feeder 300. FIG.
As shown in FIG. 25 , the container supply section 300 includes a rail-shaped tray housing section 303 and a tray peeling device 304 .
The tray accommodating portion 303 is composed of a rail-shaped frame that accommodates a large number of stacked empty trays G1 and slides and guides them obliquely downward while preventing them from falling off.
Further, the tray peeling device 304 peels and takes out the trays G1 one by one from the lower end portion of the tray accommodating portion 303. As shown in FIG.
The tray peeling device 304 comprises a rotating arm 307 having a suction cup 306 at its tip, and an electric motor 308 for rotating the rotating arm 307 .
The suction cup 306 is connected to the tip of an intake pipe (not shown) routed in the rotating arm 307, and when the rotating arm 307 is rotated upward, a negative pressure is generated to It is configured to attract the lower surface of G1.
After this attraction, the rotating arm 307 is rotated downward to release the negative pressure, and the tray G1 that has been attracted is placed on the tray conveying device 305 .

The tray conveying device 305 conveys the tray G1 peeled by the tray peeling device 304 in a direction orthogonal to the above-mentioned conveying section 5 in plan view. It is made to pass from the right side to the left side in the space Q formed below 202 .
The tray conveying device 305 is constructed by winding an endless chain 316 between a driving sprocket 315 arranged on the conveying end side and a driven sprocket 314 arranged on the conveying starting end side.
The endless chain 316 is provided with a large number of locking plates 317 spaced apart corresponding to the width of the tray G1.

Further, the transport guide rails 318 having a U-shaped cross section for guiding transport while regulating the front and rear positions and the vertical positions of the tray G1 are divided into three parts in the transport direction of the tray G1.
The conveying guide rail 318 is positioned at the first position (first position for receiving the article) PS1 where the receiving surface 201 of the article moving device 200 covers the upper side of the container G1 (the second position PS2 (the received article)). Air cylinders 319, 319 are provided for raising two adjacent trays G1, G1 conveyed and stopped immediately below the left and right receiving surfaces 201, 201 by a predetermined distance before moving to the second position (2) where the trays are unloaded).

(cutting action)
The operation conditions are set according to the type and condition of the block meat to be cut, the setting conditions of each part are changed, and the start switch 401, which will be described later, is operated.
As a result, the circular movement of the endless band blade 49 of the cutting section 4 and the driving of the conveying section 5 are started.
In this initial state, the supply unit 3 is positioned at the lower limit of the swing range. In this state, when the lumped meat MF is put into the supply unit 3 and the feed switch is turned on, the lumped meat conveying device 9 starts to drive. do.
As a result, the thrown-in lumped meat MF is conveyed forward by the conveying action of the lumped meat conveying device 9, and the front end portion of the lumped meat MF comes into contact with the rear surface of the receiving plate 43, and the front end portion of the lumped meat MF is pushed forward. position is restricted.

Then, as the supply unit 3 swings upward from this state, the blade edge of the endless band blade 49 that circulates from the right side to the left side cuts from above into the front end portions protruding from the left and right openings 35 of the massive meat MF. go.
At this time, since the position of the front end portion of the massive meat MF is restricted by the receiving plate 43, the endless band blade 49 cuts the front end portion of the massive meat MF into a uniform thickness.
When the supply unit 3 swings upward to a position near the upper limit of the swinging range, the front end of the lumpy meat MF is cut off by the endless band blade 49 .
Then, the piece of meat m cut to a predetermined thickness passes through the space T formed between the upper end of the receiving plate 43 and the lower end of the endless belt blade 49, and is arranged on the front side of the receiving plate 43. The upper peripheral surfaces of the annular plates 74, 74 of the left and right takeover rotating bodies 72, 72 are taken over.
Further, the supply unit 3 swings downward to the lower limit position of the swing range and returns to the initial state, after which the supply unit 3 swings upward again to repeat the above-described cutting of the lump meat MF.

In this way, the meat pieces m passed through the interval T and taken over to the upper peripheral surfaces of the annular plates 74, 74 of the take-over rotating bodies 72, 72 are transferred to the annular plate at the tips of the many oscillating thin rods 82. It is peeled off from the peripheral surface of 74 and folded in two.
In this way, the pieces of meat m are sequentially placed on the conveying starting end of the endless belt 96 during the conveying operation so that the pieces of meat m partially overlap each other, forming aggregates M, M of the pieces of meat m in two rows.

In these two rows of aggregates M, M, a predetermined interval (aggregate interval) P is formed between the aggregate M and the next aggregate M in each row.
In such a cutting operation, in order to adjust the thickness of the meat piece m to be cut, the electric motor 61 for thickness adjustment is operated to adjust the position of the support plate 43 with respect to the opening 35. 43, and the first supporting member 55 that supports the conveying action portion 5F on the upper side in the conveying direction moves in the front-rear direction.
However, since the front support base 116 that supports the conveying working portion 5R on the downstream side in the conveying direction is integrally attached to the third supporting member 53 on the side of the machine base 2, the influence of the position adjustment of the receiving plate 43 is eliminated. It does not move back and forth when received.

For this reason, even if the thickness of the meat piece m to be cut is adjusted, the position of the conveying action portion 5R on the lower side in the conveying direction in the conveying portion 5 does not change. The transfer position of the piece of meat m or the aggregate M of the piece of meat m is stabilized.
That is, the carrying-out position of the piece of meat m or aggregate M with respect to the receiving surface 201 of the article moving device 200 provided in the storage section 6 is less likely to change, and the subsequent storage operation can be performed smoothly.
In addition, since the positional relationship between the receiving plate 43 and the conveying action portion 5F on the upper side of the conveying direction in the conveying portion 5 does not change, the cut and folded piece of meat m is smoothly transferred to the conveying action portion 5F and conveyed. be.

(Containment operation)
The two rows of aggregates M, M formed by the above-described cutting work are conveyed to the storage section 6 in a state in which a predetermined narrow space is formed between each row.
As shown in FIGS. 30 to 37, the interval between each row in the aggregates M, M being conveyed is called "flesh row interval P0".

(Taking over aggregates onto receiving surface)
Thus, as shown in FIGS. 28 and 29, at the start of the accommodation operation, first, the two rows of aggregates M, M conveyed with this meat row interval P0 are moved back and forth during the conveyance operation. While moving the conveying end portion of the moving conveyor 95 rearward, the articles are lowered onto the left and right receiving surfaces 201, 201 of the article moving device 200 to take over.
As a result, as shown in FIGS. 16, 30 and 31, even when the left and right aggregates M, M are inherited on the left and right receiving surfaces 201, 201, the left and right aggregates M, M are spaced apart from each other. The row spacing remains P0.

In this state, the two trays G1 and G1 need to be placed side by side under the left and right receiving surfaces 201 and 201, but are spaced apart so that the two trays G1 and G1 do not overlap. There is a need to.
As a result, the center position of each assembly M inherited on the receiving surface 201 in the horizontal direction and the center position of the tray G1 in the horizontal direction are deviated in the horizontal direction. When the aggregate M is dropped, a situation may occur in which the aggregate M protrudes from the tray G1.
(In FIGS. 30 and 31, the positional deviation between the assembly M indicated by the solid line and the tray G1 indicated by the broken line.)
The lateral positional deviation between the aggregates M, M and the trays G1, G1 is eliminated as follows.

(1st stage operation)
First, as shown in FIGS. 16, 17, 30, and 31, the left and right first air cylinders 225, 225 are extended to bring the left and right receiving surfaces 201, 201 closest to each other, and the left and right receiving plates 202, 202 (strictly speaking, the interval between the folded portions of the left and right transfer belts 295, 295) is the minimum interval P1. On 201 inherit two rows of aggregates M,M.
Thereafter, as shown in FIGS. 18 and 32, the left and right first air cylinders 225, 225 are shortened by a set amount to move the left and right moving units 200L, 200R outward (opposite directions). , and the space between the inner ends of the left and right receiving surfaces 201, 201 is expanded to the intermediate space P2.
In this way, the position of the left and right receiving surfaces 201, 201 in a state where the inner end portions of the left and right receiving surfaces 201, 201 are spaced at the middle distance P2 is defined as a second position PS2.

In this manner, the left and right receiving surfaces 201, 201 extend from the minimum interval P1 to the intermediate interval P2 until the inner end portions of the left and right receiving surfaces 201, 201 are expanded to the trays G1, G1. The receiving surfaces 201, 201 substantially cover the upper sides of the trays G1, G1.
In this way, the position of the left and right receiving surfaces 201, 201 in a state where the distance between the inner ends of the left and right receiving surfaces 201, 201 is the minimum distance P1 is defined as a first position PS1.
In this state, the aggregates M, M of the pieces of meat m on the left and right receiving surfaces 201, 201 are positioned directly above the trays G1, G1 waiting on the lower side.

(Second stage operation)
In this state, the air cylinder 319 of the tray transfer section 302 is operated to raise the trays G1, G1 to the set position.
Then, as shown in FIGS. 20 and 36, during or after the trays G1, G1 are raised, the left and right second air cylinders 241, 241 are extended by a set amount, and the inner sides of the left and right receiving surfaces 201, 201 are moved. Expand the edge spacing to the maximum spacing P3.
In this way, the position of the left and right receiving surfaces 201, 201 when the distance between the inner ends of the left and right receiving surfaces 201, 201 is the maximum distance P3 is defined as a third position PS3.
In this state, the left and right receiving surfaces 201, 201 are retracted from the upper side of the trays G1, G1 to the left and right outer sides, and the upper side of the trays G1, G1 is opened.
34 and 35 show a state in which the distance between the inner ends of the left and right receiving surfaces 201, 201 is at the middle distance PM, which is in the middle of expanding from the middle distance P2 to the maximum distance P3.

In this way, the interval between the inner ends of the left and right receiving surfaces 201, 201 expands from the intermediate interval P2 to the maximum interval P3 via the intermediate interval PM, that is, both the receiving surfaces 201, 201 are at the first position. When moving from PS1 to the second position PS2, the respective transfer belts 295, 295 move in the direction opposite to the moving direction of the receiving surfaces 201, 201 at the same speed.
As a result, the aggregates M, M are dropped into the trays G1, G1 and accommodated without changing their positions in the left-right and front-rear directions.
The trays G1, G1 containing the aggregates M, M are lowered to the initial position, passed through the space Q by the tray conveying device 305, and carried out to the left outside.

The above operation is repeated in synchronization with the intervals at which the aggregates M, M are conveyed.
As described above, when the left and right receiving surfaces 201, 201 (the left and right receiving plates 202, 202 and the left and right transfer belts 295, 295) are expanded to the maximum distance P3, the conveying action portion is positioned within the maximum distance P3. 5R is located. (The maximum interval P3 is larger than the lateral width of the conveying action portion 5R.)
In addition, the lower winding area of the endless belt 96 on the reciprocating conveyor 95 needs to be set at a height close to the upper side of the left and right receiving surfaces 201, 201 to improve the transferability of the assembly M.

Therefore, when slack is generated in the lower winding area of the endless belt 96 on the reciprocating conveyor 95, the left and right second air cylinders 241, 241 are operated to shorten the set amount so that the left and right receiving surfaces 201, 201 are spaced at an intermediate distance. When returning to P2, the inner ends of the left and right receiving plates 202 , 202 may interfere with the endless belt 96 of the reciprocating conveyor 95 .
However, as described above, since the lower winding area DA of the endless belt 96 on the reciprocating conveyor 95 is inclined forward and downward, the lower winding area DA of the endless belt 96 is inclined when the assembly M is accommodated. Interference with the inner ends of the left and right receiving plates 202, 202 (strictly speaking, the folded ends of the left and right transfer belts 295, 295) due to the sagging of the belt can be prevented.

(Slicer control circuit)
The slicer 1 configured as described above cuts the chunky meat MF from its tip to a predetermined thickness, folds the cut meat pieces m, and partially overlaps the folded meat pieces m. are arranged side by side to form an aggregate M.
Thus, as shown in FIG. 40, a start switch 401, an automatic meat piece height setting on/off switch 402, and a chunk meat height manual setting switch 403 are connected to the input side of a controller 400 provided in the control unit 7. , parallel length manual setting switch 404, parallel number manual setting switch 405, parallel number automatic control on/off switch 406, left lump meat height measurement potentiometer 407, right lump meat height measurement potentiometer 408, A supply unit swing angle measuring potentiometer 409, a lower endless belt movement distance measuring sensor 410, a left takeover rotating body rotation phase measuring potentiometer 411, a right takeover rotating body rotating phase measuring potentiometer 412, and a left rod rotation.

(Formation control of aggregates of meat pieces)
The formation control of the aggregate M of the pieces of meat m will now be described along the flow charts shown in FIGS. 41 and 42 .
In addition, below, the state which supplies lump meat MF to only one conveyance path 20 of the conveyance paths 20 and 20 on either side of the supply part 3 is demonstrated.
However, the lower endless belt (“first endless belt” in the claim) 25 provided over the left and right conveying passages 20, 20 of the supply unit 3 and the endless belt (“second endless belt” in the claim) provided in the conveying unit 5 ) 96 is divided into left and right (“first left endless belt and first right endless belt” and “second left endless belt and second right endless belt” in the claims) and driven independently of each other. If so, it is also possible to control the formation of the aggregate M by supplying the lumped meat MF to both the left and right conveying paths 20 , 20 .
The "meat piece height" in this embodiment means the length of the meat piece m in the transport direction when the meat piece m cut in the vertical direction is transported by the endless belt 96. As shown in FIG.
A description will be given based on the flow charts shown in FIGS. 41 and 42. FIG.

(First flow)
First, the operating conditions are set according to the type and state of the chunky meat MF to be cut, the setting conditions of each section are changed, and the start switch 401 is operated.
As a result, based on the measurement results of the sensors 407 to 417, the controller 400 outputs control outputs to the motor drivers 424 to 432 and 434 to 436 and the valve solenoid 433 to drive the cutting section 4 and the supply section. 3 and the driving of the conveying unit 5 are started. (STEP1)
As a result, cutting (slicing) of the chunky meat MF and folding of the cut meat pieces m are started. The meat pieces m are successively placed on the conveying starting end of the belt 96 to form aggregates M, M of the meat pieces m.
A predetermined interval (aggregate interval) P, which will be described later, is formed between aggregates M successively formed in this way and the next aggregate M. As shown in FIG.

When the meat piece height automatic setting ON/OFF switch 402 is operated (or operated) to the ON side (ON) in the formation of the aggregate M of the meat pieces m, the automatic setting of the meat piece height is turned on ( effective state), and shifts to the height measurement (thickness measurement) of the massive meat MF. (STEP2)

In this height measurement (thickness measurement) of the lumped meat MF, the potentiometer (the billing The height (thickness) of the tip portion of the chunky meat MF is measured by the “measuring means” in the section above), and a chunky meat height measurement value (thickness measurement value) X is obtained. (STEP3)

Based on this, the height of the piece of meat m (the length in the row direction) is calculated.
That is, the meat piece height calculation value A that is temporarily calculated is calculated from the lump meat height measurement value X and the variable Y by the following calculation formula. (STEP4)
A = X x Y
The value of Y varies depending on the folding position of the piece of meat m, and Y=0.5 when the piece of meat is folded at the center position of the height of the piece of meat.
(STEP 4 corresponds to the "length calculating means" in the claims.)

The meat piece height calculated value A thus calculated, the parallel length manual setting value E set by operating the parallel length manual setting switch 404, and the parallel number manual setting value set by the parallel number manual setting switch 405 From F, a parallel form of manual setting is established. (STEP5)
The parallel length manual setting value E is changed by the parallel length manual setting switch 404 according to the size of the tray G1 to be used (length in the conveying direction). It is what I did. In addition, the parallel number manual setting value F is obtained by arbitrarily changing and setting the number of meat pieces m forming each aggregate M by operating the parallel number manual setting switch 405 .

Then, when the parallel sheet number automatic control ON/OFF switch 406 is operated (or operated) to the ON side (or is operated), the process shifts to the parallel reference value automatic setting performed at the automatic control ON time T0. (STEP6)

In this parallel reference value automatic setting, the calculated value A0 of the height of the meat piece m at time T0 is replaced with the meat piece height reference value G and stored, and the parallel number manual setting value F is replaced with the parallel number reference value H , and the number of parallel sheets I is calculated. (STEP7)

This parallel number I is calculated by the following formula from the meat piece height calculation value A, the meat piece height reference value G, and the parallel number reference value H, and the calculated value is rounded down to the decimal point and obtained as an integer. . (STEP8)
Calculated value = (G/A) x H
For example, when the value calculated by the above formula is 5.1 and 5.9, the parallel number of sheets is 5 in both cases.
The meat piece height calculation value A is always calculated, but the number of pieces does not change while the acquired integer value does not change due to rounding down the decimal point. (This corresponds to "prohibition of automatic change in the number of pieces of meat" in the claim.)
(STEPs 7 and 8 correspond to the "quantity changing means" in the claims.)

The parallel pitch K is calculated from the parallel length manually set value E, the meat piece height calculated value A, and the parallel number I by the following formula. (STEP9)
K=(EA)/(I-1)

Then, based on the measurement result of the conveyor moving distance measuring sensor 417, while driving the endless belt 96 forming the conveyor of the conveying unit 5 by a distance equal to the parallel pitch K (STEP 10), the cut out from the cutting unit 4 is performed. The operation of placing the folded pieces of meat m on the endless belt 96 one by one is repeatedly executed. (STEP11)
It should be noted that even if the calculated value of the parallel pitch K changes during the formation of one aggregate, the change of the parallel pitch is prohibited until the number of paralleled sheets reaches the integer obtained in STEP8. (This corresponds to "prohibition of automatic change of pitch for arranging pieces of meat" in the claim.)
(Steps 9 to 11 correspond to the "pitch changing means" in the claims.)

The number of sheets placed and arranged on the endless belt 96 is determined by the number of reciprocating rotations of the left rod rotation angle detection potentiometer 413 or the right rod rotation angle detection potentiometer 414. When the parallel number of sheets I is reached, the calculation of the amount of movement of the conveyor for forming the gap between aggregates is performed. (STEP12)

The amount of movement P of the conveyor for forming the cluster interval is calculated by the following formula from the effective transport length (conveyor effective length) L of the endless belt 96, the parallel length manually set value E, and the number R of the clusters. be done.
(STEP13)
P = (L - E x R) / (R - 1)
This conveyor movement amount P is the interval between the adjacent aggregates M, M, and is measured by the conveyor movement distance measurement sensor 417 .

As described above, the aggregates M are intermittently formed on the endless belt 96 with the interval P between the aggregates and conveyed.
FIG. 43 shows an aggregate M of meat pieces m thus formed.

Then, in a state where this assembly M reaches the conveying end portion of the endless belt 96 (rear end portion of the conveyor), the output from the controller 400 to the expansion/contraction motor driver 436 causes the expansion/contraction electric motor 135 to operate. The conveying end of belt 96 (the trailing end of the conveyor) extends rearward.
As a result, the conveying terminal end of the endless belt 96 advances above the rear end of the tray G1 waiting below the receiving surface 201 on one of the left and right sides of the article moving device 200 . (STEP14)

Then, when the conveying distance of the endless belt 96 (conveyor moving distance) measured by the conveyor moving distance measuring sensor 417 reaches the set distance (STEP 15. The aggregate M at the trailing end has separated from the conveying end portion). ), an output from the controller 400 to the extension/contraction motor driver 436 causes the extension/contraction electric motor 135 to operate in the opposite direction, and the conveying end portion of the endless belt 96 retreats rearward from the tray G1. (STEP16)

As described above, the assembly M separated from the transport end of the endless belt 96 is taken over onto the receiving surface 201 on one of the left and right sides of the article moving device 200 and accommodated in the tray G1.

(Second flow)
On the other hand, in STEP 6, when the parallel number automatic control switch 406 is operated (or operated) to the turning side (OFF), the above-mentioned parallel reference value automatic setting is not performed, and parallel pitch calculation is performed. Transition.

This parallel pitch K is calculated from the parallel length manually set value E, the meat piece height calculated value A, and the parallel number manually set value F by the following formula. (STEP17)
K=(EA)/(F-1)

Then, based on the measurement result of the conveyor movement distance measuring sensor 417, while driving the endless belt 96 forming the conveyor of the transport unit 5 by a distance equal to the parallel pitch K (STEP 18), the cut out from the cutting unit 4 is performed. The operation of placing the folded pieces of meat m on the endless belt 96 one by one is repeatedly executed. (STEP19)

The number of sheets placed and arranged on the endless belt 96 is determined by the number of reciprocating rotations of the left rod rotation angle detection potentiometer 413 or the right rod rotation angle detection potentiometer 414. When the parallel number of sheets coincides with the manually set value F, the process shifts to the calculation of the conveyor movement amount for forming the aggregate interval. (STEP20)
Since the subsequent steps are common to the first flow, the explanation is omitted.

(Third flow)
Also, in STEP 2, when the meat piece height automatic setting switch 402 is operated to the cutting side (OFF) (or if it is operated), the meat piece height is not calculated, and the mode shifts to manual setting in parallel mode. do.
Here, the meat piece height setting value J set by the lump meat height manual setting switch 403, the parallel length manual setting value E set by operating the parallel length manual setting switch 404, and the parallel number manual setting switch 405 Manual setting of the parallel mode is established from the set value F for the parallel number of sheets, and the process shifts to calculation of the parallel pitch. (STEP21)

This parallel pitch K is calculated from the parallel length manually set value E, the meat piece height calculated value A, and the parallel number manually set value F by the following formula, as in STEP17. (STEP22)
K=(EA)/(F-1)
Since the subsequent steps are common to the second flow, the explanation is omitted.

(State of aggregate formation)
Thus, FIG. 43 illustrates the state of aggregates formed as described above.
In this example, an aggregate M1 formed by arranging five meat pieces m so that at least a part of them overlap, an aggregate M2 formed by arranging six meat pieces m in a similar manner, and seven Aggregates M3 formed by arranging meat pieces m in parallel are shown side by side at the same time.
However, this is used for convenience of explanation, and in the present invention, it is not limited to the existence of aggregates M having different numbers of meat pieces on the same endless belt 96 .

Thus, in the aggregate M1, five pieces of meat m1 having a length (height) A are arranged in parallel at a pitch K to form an aggregate having a total length E.
In addition, the aggregate M2 forms an aggregate having a total length E by arranging six meat pieces m2 shorter than the meat pieces m1 in parallel at a pitch shorter than K.
In the aggregate M3, seven pieces of meat m3 shorter than the aggregate M2 are arranged in parallel at a pitch shorter than that of the aggregate M2 to form an aggregate having a total length E.
Thus, by changing the number and pitch of the meat pieces m to be arranged in parallel according to the height of the meat pieces m, the total length and weight of the aggregate M of the meat pieces m can be uniformed.

That is, as shown in FIG. 44, the chunky meat MF usually has a predetermined length, and the height V1 of the front end is different from the height V2 of the rear end. Its height varies irregularly.
Therefore, when the meat is cut (sliced) with a constant thickness in the vertical direction, pieces of meat with different heights are formed depending on the cut portions, and the weight of the sliced pieces of meat is not uniform.
On the other hand, as described above, in addition to controlling the parallel pitch, by controlling the parallel number of pieces, as shown in FIG. It is possible to reduce the variation in the total weight of each assembly M by, for example, bringing it closer to α.
