Description

  The present invention relates to a tofu packing apparatus for sharing a process of packing tofu cut into a predetermined size into a packing pack in a sales form in an automatic tofu production line.

  The automatic tofu production line using soybeans as a raw material functionally connects various devices that share various processes from raw materials to pack-type tofu products that are sold in packs via a conveyance line. It is a large process equipment.

  In an automatic production line for tofu, devices for sharing various types of processes with different processing contents are connected in series. In addition, there are a wide variety of processing contents handled by each connected apparatus, and processes having different processing levels are mixed. A process with a low degree of processing difficulty is easy to speed up and has a low product defect rate. On the other hand, a process with a high degree of processing difficulty is difficult to speed up easily, and the rate of product defects is high. As a result, the operating speed of the automatic tofu production line is determined by the rate-limiting process by the equipment that shares the difficult tasks among the various types of equipment that make up the automatic production line, and the actual operating speed and yield are determined. Has been. Therefore, in order to stably increase the speed of the automatic production line for tofu, it is required to intensively take improvement measures by paying attention to the devices that share highly difficult work.

One of the most difficult tasks in the automatic tofu production line is the packing of tofu.
As a method for packing tofu, there are conventionally a method performed in land space (“land packing”) and a method performed in water. The so-called “land packing” (also called hill packing) method in which the packing operation is carried out in space is a combination of a conveying conveyor for conveying tofu and a packing conveyor for supplying packaging packs in an orthogonal direction, and the tofu is transferred to the conveying conveyor. After moving from the end to the slide table by a company-specific device (for example, an extrusion blade), pressing it against a fixed stopper and positioning it on the packing pack on the pack conveyor, then retracting the slide table and packaging the tofu positioned It is dropped into a pack (see Patent Document 1). Further, the tofu is fed on an inclined chute plate by an extruding blade, dropped as it is, and stored in a packaging pack that operates in synchronism (see Patent Document 3).

  On the other hand, the method of packing tofu in water is a polite method in accordance with traditional manual work, and is a method of accurately cutting and storing in a packaging pack so as not to damage the tofu. Also, it is a method adopted paying attention to the advantage that it can be handled while reducing the weight of tofu on handling by acting buoyancy on tofu, introducing a pack conveyor into the water tank, and cutting the tofu cut in water Distributes the transporting interval of the supplied pack, positions the individual tofu distributed by a unique positioning device, releases the tofu, and stores the tofu in a pack so that the tofu is scooped by the packaging pack. And send it out of the water tank (see Patent Document 2).

  Further, the present applicant has already disclosed a tofu packing device by sandwiching the tofu on the conveyor belt by a drive mechanism that drives the tofu synchronously, and dropping and storing the sandwiched tofu in a packaging pack (two rows). (See Patent Document 4 and Patent Document 5).

Japanese Patent No. 3343134 Japanese Patent Publication No. 7-95927 JP 2007-006759 A JP 2012-140158 A JP2012-180130A

  However, sandwiching tofu during packing is good for hard tofu, but not preferable for soft tofu. That is, since the stopper 50 disclosed in Patent Document 1 is a fixed type, when a plurality of rows of tofu groups are processed, the mechanism interferes with the feed blade and can handle only one row unit. In addition, there is a description that the tofu is sandwiched between the feed blade 20 and the stopper 50. In the case of soft tofu, the tofu is distorted and damaged by excessive force, or when the tofu is tilted and dropped, the position of the tofu is tilted, or the drop position is delicate. There was a risk that the packing accuracy such as shift would be affected by the quality of tofu. Therefore, it can only be applied to hard tofu. Moreover, in patent document 3, although tofu is moved until it presses against a stopper with the braid | blade for extrusion, also in this case, tofu will be inserted and it is not preferable with respect to soft tofu. In addition, a slide table having a tilting mechanism that tilts and stores it with respect to the packaging pack from the horizontal posture has been developed, but if tofu is sandwiched, it becomes a hindrance when tilting and storing. There was a thing.

  On the other hand, the present applicant has developed a technique for cutting out and transporting tofu for a plurality of rows in the row direction (Patent Literature 4, Patent Literature 5), but the appearance of a packer with high processing capability corresponding to this has emerged. It was over. In other words, the conventional device is assumed to be substantially in units of two lines, and it is desirable to pack more than that number at the same time, but with the conventional pinching mechanism, up to about three lines are possible, I had to say that there was a limit to cutting and packing more lines. In addition, there are similar problems in the pinching mechanism as described above.

  In addition, recent packing work requires a variety of variations as well as high-speed processing (for example, simultaneous packing of a large number of land packs). Correspondence to the variation of the sheath shape is required, and the conveyance according to this is also required. Moreover, considering the situation where water separation is likely to occur and the taste is quickly removed, and the situation where various germs are generated, it is preferable to cut into a size to be packed as soon as possible before packing.

  Therefore, the object of the present invention is to pack the pack so that soft tofu is not sandwiched as much as possible at the time of packing, and to pack a large number of tofu arranged in a plurality of rows all at once in the packing pack. An object of the present invention is to provide a tofu packing device capable of dramatically increasing the processing capacity. In addition, during the packing process, a tofu packing device that cuts into various variations in response to high-speed processing and soft tofu, and cuts into the size to be packed during packing. It is to provide.

(1) The present invention is a tofu packing device that transports a continuously-formed tofu of a predetermined size in a mass-produced tofu packing device that packs a plurality of unit tofu into a packaging pack on land. A transporting conveyor, a packaging pack transporting device that transports the packaging pack to the downstream side of the transporting conveyor, a slide table disposed above the packaging pack transporting device, and pushing out the tofu of the predetermined size from the transporting conveyor onto the slide table At least one extrusion blade and unit tofu on the slide table to be packed are arranged in a matrix (N rows and M columns) and arranged in a matrix (M rows) according to the position of the packaging pack. At least one positioning blade for positioning so that the unit tofu is retracted by the slide table. When dropping and storing in the packaging pack, the tofu that drops at least one of the extrusion blade and / or the positioning blade is used as a drop guide means for guiding the tofu into the packaging pack. That is, guidance is performed from one direction (one side direction), two directions (two side directions), three directions (three side directions), or four directions (four side directions) around the four sides of the packaging pack. Here, the tofu is not gripped so as to be distorted by the extrusion blade and / or the positioning blade, etc., preferably slightly touching or slightly separated, or either of the blades is tofu. It is preferable to pack in a state separated from the package. Further, when the tofu is dropped and stored in the packaging pack by the retracting operation of the slide table, the pushing blade is released from the tofu contact, and only the positioning blade is used as a drop guide means in the tofu packaging pack. It is preferable to guide.
According to the present invention, after the unit tofu having a size to be packed by the extrusion blade is extruded on the slide table, each unit of the pack below the slide table is synchronized with or interlocked with the movable positioning blade. The position is aligned, and the extruding blade or the positioning blade is touched slightly or slightly so as not to greatly distort the tofu from one or two directions, or is completely separated from the tofu. Then, the slide table is retracted and the tofu is dropped and stored in the packaging pack. That is, the tofu that drops at least one of the extrusion blade and the positioning blade is used as a drop guide means for guiding the tofu into the packaging pack. At this time, the positioning blade is movable, not fixed, and can efficiently position a plurality of rows of unit tofu so as not to interfere with the extrusion blade, and synchronizes, synchronizes and interlocks with the extrusion blade. Thus, it has a driving mechanism in the vertical direction and the column direction. Here, the extrusion blade and the positioning blade may be configured to operate together by a common drive mechanism. Therefore, until the tofu falling during packing is started from the slide table operation until the tofu is stored in the packaging pack, at least one of the pushing blade and the positioning blade is stopped so as to function as a drop guide means. In this way, it is possible to pack accurately by the drop guide means that guides in one or two directions so as not to be pinched as much as possible. The extrusion blade and the positioning blade are positioned in the row direction, and are similarly provided with a guide guide (described later) for positioning in the column direction and a row direction positioning means (not shown) provided with a drive mechanism. Further, the packing can be more accurately performed by the drop guide means for guiding from 2 to 4 directions.

The present invention further includes at least one cutting blade for cutting the tofu of the predetermined size into a size to be packed in the process of pushing the tofu on the conveyor, the slide table, or the conveyor to the slide table. A predetermined interval enlarging means for performing an operation of opening the tofu at a predetermined interval after being cut to a size to be packed by the cutting blade, and dropping the tofu by the retraction operation of the slide table and storing it in the packaging pack When doing, you may employ | adopt the structure which uses the tofu which drops at least any one of the said blade for an extrusion, a positioning blade, or the said guide as a fall guide means to guide from 1 to 4 directions in a packaging pack.
And, the predetermined interval expanding means is at least one of the cutting blade on the transport conveyor or the slide table, or a split slide table that is divided so as to be operable to open at a predetermined interval when the slide table packs the tofu. A configuration using either one can be employed. Further, a plurality of rows of tofu are conveyed by a conveyor, and a plurality of extrusion blades for extruding a plurality of rows of strip-like tofu that are conveyed on the conveyor or the slide table at the same time, and the conveyor or slide table. A plurality of cutting blades that perform the operation of simultaneously cutting the plurality of rows of tofu that have been transported or extruded in row units above in a row unit and simultaneously opening them in predetermined intervals by the predetermined interval enlarging means, A configuration having a plurality of positioning blades that simultaneously position a plurality of rows of tofu so as to face the downstream side of the extruding blade on a conveyor or a slide table may be employed. The cutting blade and the extruding blade may be used in combination, reducing the number of parts, reducing the cost of the apparatus, improving the cleaning property, and reducing the risk of contamination with bacteria.

Further, as the present invention, it is possible to adopt a configuration in which the pushing blade and the positioning blade are constituted by one hanging drive mechanism. According to the present invention, there is no need to reciprocate the pushing blade and the positioning blade in the front-rear direction by separate driving means, and the above-described effects can be realized with a structurally simple structure. That is, the extrusion blade and the positioning blade can be realized as one drive means. Each blade has lifting means, and can be lifted and lowered in combination with the reciprocating motion.
(2) The present invention is the tofu packing device according to the above (1), wherein when the tofu is dropped and stored in the packaging pack by the retracting operation of the slide table, the tofu The tofu falling in the packaging pack is guided in the row direction by the pushing blade and / or the front and rear positioning blades and / or in the row direction by the right and left positioning blades along the row direction. It is used as a drop guide means for guiding from two or four directions.
According to the present invention, the pushing blade and / or the positioning blade guide or drop guide from one or two directions in the column direction, and the row direction by the left or right positioning blades along the fixed or movable column direction. By positioning or guiding the tofu from 1 to 2 directions, it is possible to realize accurate packing by positioning or guiding the unit tofu from 2 directions, 3 directions or 4 directions.

According to the present invention, the extrusion blade serves not only for cutting tofu but also for adjusting the interval, and also serves as a drop guide means for packing. That is, immediately before the tofu is dropped by the sliding operation of the slide table and stored in the packaging pack, the blade for extrusion is released from the contact with the tofu, and is kept slightly separated from the tofu. This is to the extent that some or slight contact occurs when the tofu falls, and prevents the tofu from dropping greatly. Further, the surface adhesion force (due to the surface tension of water) generated by a slight amount of water generated on the contact surface between the blade surface and the tofu is previously reduced or removed, so that the tofu falling posture can be stabilized. Further, if the tofu is hard to some extent, it may be so far away that the tofu does not come into contact at all when it falls. In that case, the processing time may be shortened as much as possible by the operation of quickly returning the pushing blade to the original position, thereby increasing the processing capacity. In this way, the soft tofu can be packed in an accurately and stably falling posture without damaging as much as possible during packing.

The dimensional relationship with the positioning hole 2H is set such that the edge portion of the packaging pack P remains on the top plate 22 when the packaging pack P is dropped into the positioning hole 2H from the bottom surface side. A large number of packaging packs P mounted on the pack conveyor 21 form a packaging pack group P having two columns and four rows (FIGS. 9 to 11).

  The push-up mechanism 23 is installed in the frame of the pack conveyor 21. The push-up mechanism 23 includes a lifting plate 2P that secures bending strength by attaching a reinforcing channel 2F to the back surface, and one or a plurality of pushers that are installed with the operating rod facing upward on the back surface side of the lifting plate 2P. It consists of a cylinder C7. The width of the elevating plate 2P is a width that can simultaneously cover the bottom surfaces of the two packaging packs P, P dropped into each top plate 22 and can move up and down without interfering with the left and right flanges of the top plate 22. The length of the lifting plate 2P is set to be equivalent to the width of the conveyor 10 (that is, the row direction of the tofu B, and the width of the lifting plate 2P is the row direction of the tofu B). The elevating plate 2P is a form of the push-up mechanism 23, and is not particularly limited as long as it pushes up while the bottom of the packaging pack P is made substantially horizontal. In addition, it is also preferable to arrange positioning means such as a concave portion and a guide that match the shape of the bottom surface of the packaging pack P on the lifting plate 2P, and it is possible to prevent displacement when the packaging pack is pushed up.

  In the pack conveyor 21, the push-up mechanism 23 pushes up the lifting plate by the pusher cylinder C7, thereby lifting the top plate 22 and lifting the top plate 22 in two rows and four rows (M columns and N rows). The packaging pack P can be raised within the range of the length of the lifting plate. If the thickness of the top plate 22 is ignored, each packaging pack P can be raised by the height of the container by this operation. Since the load applied to the push-up mechanism 23 is only the weight of the packaging pack P, it can be ignored. It should be noted that the falling impact is preferably lowered by slowing down the falling speed by matching the timing of the lifting plate in accordance with the movement of the unit tofu stored in the pack in accordance with the movement of the unit tofu (soccer ball). Same as trap action). Even if a certain amount of water is injected into the packaging pack P, it does not make a big difference. In the present application, the top plate 22 may be lifted. However, it is particularly preferable to push up only the packaging pack because the load on the chain CH, the pack conveyor 21 and the packaging pack transport device 20 is small. Each packaging pack P is filled with an appropriate amount of water in order to moderate the drop impact of soft tofu and suppress damage. However, each packaging pack P may be filled.

Next, the packing operation of the unit tofu B of this embodiment will be described.
In the following description of the operation, for all the cylinders C1 to C3, Ca, and Cb, the operation in the direction in which the operating rod is stored in the cylinder is simply indicated as “−operation” and is stored in the cylinder. The operation in the direction in which the operating rod is pushed out is simply displayed as “+ operation”.

The unit tofu B cut to a predetermined size on the conveyor 10 is arranged in a certain matrix interval so as to match the packaging pack P in which a predetermined number is arranged in the width direction (and the traveling direction) of the conveyor 10. Are sequentially transported as unit tofu B. The drive mechanism 40 travels in the upstream direction while the horizontal moving cylinder C1 is operated and the traveling vehicle 11a coupled to the horizontal moving cylinder C1 is guided by the track rail 11. Although the traveling vehicle 11 a is supported by being suspended, it moves in the upstream direction and is placed on the end of the conveyor 10. The pack conveyor of the packaging pack transport device 20 is located immediately below the slide tables S1 and S2 at this position, and the packaging pack P is prepared. The packaging pack P is lifted up to near the slide tables S1 and S2 by the + operation of the vertical moving cylinder C7 of the push-up mechanism 23 and is on standby.
With the operation of the transport conveyor 10, when the sensor system (not shown) detects that the tofu B located in the most downstream direction descends and reaches the standby blade b, the transport conveyor 10 pauses. To do. Next, the vertical movement cylinders Ca and Cb operate in a positive direction, and the comb-shaped suspension body 40A moves down. At this time, the extrusion blade b and the positioning blade c are between the first tofu B in the first row and the second tofu B in the second row, and between the tofu B in the second row and the tofu B in the third row. To descend. The sensor system is not particularly limited as long as it is a sensor or measuring means that can recognize the presence of a workpiece, such as a reflective displacement sensor, a transmissive photoelectric sensor, or a fiber sensor.

  When the horizontal moving cylinder C1 moves + after the suspension body 40 is completely lowered, the comb-shaped suspension body 40 moves horizontally so as to push out the unit tofu B all at once. That is, by driving a large number of extrusion blades b, for example, 4 rows and 7 columns of tofu B are simultaneously moved toward the slide tables S1 and S2 in a short time (FIGS. 2, 12B and 12C). . 12A and 12B are side views, and FIGS. 12C and 12D are top views.

  The pushing blade b horizontally moves in the downstream direction while maintaining the state of four rows of tofu with the horizontal movement of the traveling vehicle 11a, and is positioned on the slide tables S1 and S2 by being regulated by the stroke of the horizontal movement cylinder C1. Is done. During this time, the push-up mechanism 23 of the packaging pack transport device 20 moves the pusher cylinder C7 to + to raise the packaging pack P in 4 rows and 7 rows located below the slide tables S1 and S2 to just below the slide tables S1 and S2. Let me wait.

  Next, the horizontal motion cylinders Ca and Cb perform a negative operation, and are pulled out to the slide tables S1 and S2 on which the tofu B is placed. When the slide tables S1 and S2 are retracted, the upstream side surface or downstream side surface of a large number of blades b for extrusion and the downstream side surface or each upstream side surface of the unit tofu B are stationary as drop guide means and guide the unit tofu B. When dropped, a large number of tofu B falls horizontally in the corresponding packaging pack P along the blades b and c (FIGS. 12B and 12D). FIG. 12C is a diagram in a state where the slide tables S1 and S2 are closed, and FIG. 12D is a diagram in a state where the slide tables S1 and S2 are opened.

  Immediately before, simultaneously with, or immediately after receiving the tofu B into the packaging pack, the push-up mechanism 23 operates the pusher cylinder C7 to return the packaging pack P that has been lifted to the original position of the pack conveyor 20. In addition, a large number of extrusion blades b and positioning blades c that have completed the storage operation of tofu B are simultaneously lifted by the -operation of the vertical movement cylinder C3, and are in preparation for returning to the standby state again. . As the lowering operation of the push-up mechanism 23, the slide tables S1 and S2 operate simultaneously with the start of retraction or immediately after or immediately before, and receive the tofu B that falls while the packaging pack P is descending into the packaging pack. In addition, the descent operation may be adjusted appropriately for acceleration / deceleration so that the impact when the tofu B falls and is stored in the packaging pack P can be more reliably prevented. preferable.

As the return operation, the slide tables S1 and S2 that have been retracted take a horizontal posture at the end of the transport conveyor 10 by the-operation of the horizontal moving cylinders Ca and Cb, and the pushing blade b is connected to the horizontal moving cylinder C1. -Turn back upstream by movement. During this time, the conveyor 10 moves the tofu B in the 5th, 6th, 7th, and 8th lines in the downstream direction, and the pack conveyor of the packaging pack transporter 20 is a packaging pack in which the tofu B is stored. P is carried out, and the next empty packaging pack P is fed to the front of the conveyor 10 in order.
Next, in the drive mechanisms 40A and 40B, the pushing blade b returns to the conveying conveyor and the positioning blade c returns to the slide tables S1 and S2 by the + operation of the vertical movement cylinder C3.
FIG. 2 is another example of the present embodiment, in which block-like tofu is conveyed to the conveyor 10, and the extrusion blade b of the drive mechanism 40A is lowered and cut in the row direction. And it extrudes to slide table S1, S2, and adjusts the space | interval of the column direction for the thin strip-shaped tofu long in a row direction. Next, the obtained strip-shaped tofu elongated in the row direction is obtained by adjusting the row-direction interval while the alignment blade c, which also serves as the longitudinal cutting blade of the drive mechanism 40D, is cut in the column direction on the slide table. The unit tofu B is positioned from one direction in the row direction with the positioning blade c which also serves as a vertical cutting blade and then retracted, and the extruding blade b of the drive mechanism 40A descends again between the unit tofu B. As a drop guide means, it guides to the packaging pack P so as to drop along these blades b together with the retracting operation of the slide table.
FIG. 13 is another example of the present embodiment, in which block-like tofu is conveyed to the conveyor 10, and the positioning blade c that also serves as the vertical cutting blade of the drive mechanism 40D is lowered. Then, cutting in the column direction and adjusting the interval in the row direction, and adjusting the interval in the column direction while the extruding blade b of the drive mechanism 40A pushes the strip-like tofu obtained in the column direction to the slide tables S1 and S2. To do. Next, the obtained unit tofu B is positioned from one direction in the row direction by the pushing blade b of the drive mechanism 40A, and is used as it is as a drop guide means, and is dropped along these blades b together with the retracting operation of the slide table. Guide to the packaging pack P.

  FIG. 12 shows another example of the present embodiment, in which sheet-shaped or block-shaped tofu is conveyed to the conveyor 10, and the comb-shaped extrusion blade b of the drive mechanism 40 is lowered. While cutting in the row direction and extruding to the slide tables S1 and S2, adjusting the interval in the row direction and moving along the passage formed by the guide guide Ag having a fixed blade on the upstream side in the row direction Adjust the interval. The guide guide Ag includes a plurality of pairs of plates, and guides the unit tofu B between the pair of plates (passage) with a wide interval. The guide guide Ag has a predetermined interval enlargement function and also has an upstream cutting blade function. Next, when the slide tables S1 and S2 are retracted by the-operation of the horizontal moving cylinders Ca and Cb, the comb-shaped extruding blade b also serves as a positioning blade, positions the unit tofu B as it is as a drop guide means, The tofu falling along the positioning blade c and the guide guide Ag is guided to the packaging pack P from three directions.

(Second Embodiment)
FIG. 3 shows a second embodiment of the present embodiment, and this suspension drive mechanism 40 comprises a number of pushing blades b and positioning blades c as one comb-shaped suspension body 40. The horizontal motion cylinder C1 and the vertical motion cylinder C3, which are air cylinders, are driven using a drive source. When the positioning blade c of the present embodiment reaches the position of the packaging pack P by the packaging pack transport device 20, the positioning blade c temporarily stops when it is detected by a sensor system (not shown) and confirms the alignment.

Next, the packing operation of the unit tofu B of this embodiment will be described.
The unit tofu B cut to a predetermined size on the conveyor 10 is sequentially conveyed as unit tofu B in an array state with a constant matrix interval. The drive mechanism 40 travels in the upstream direction while the horizontal moving cylinder C1 is operated and the traveling vehicle 11a connected to the horizontal moving cylinder C1 is guided by the track rail 11. The pack conveyor 20 is located immediately below the slide table S and prepares a packaging pack P. The packaging pack P is lifted up to the vicinity of the slide table S by the + operation of the vertical moving cylinder C7 of the push-up mechanism 23 (FIG. 3).
At the time when it is detected by the sensor system (not shown) that the unit tofu B located in the most downstream direction has descended and reached the extrusion blade b waiting in accordance with the operation of the conveyor 10, the conveyor 10 is Pause. Next, the vertical movement cylinder C3 moves +, and the comb-shaped suspension body 40 moves downward. At this time, the blades b and c are between the first unit tofu B1 on the first row and the unit tofu B2 on the second row, and between the unit tofu B2 on the second row and the unit tofu B4 on the third row. To descend.
After the suspension body 40 is completely lowered, when the horizontal moving cylinder C1 operates +, the suspension body 40 is moved horizontally so as to push out the unit tofu B. That is, by simultaneously driving the extrusion blade b (also used as a positioning blade), the four rows of tofu B are simultaneously moved toward the slide table S (FIGS. 3B and 3C).
The blades b and c of the suspension body 40 move horizontally in the downstream direction while maintaining the state of the four rows of tofu with the horizontal movement of the traveling vehicle 11a, and are regulated by the stroke of the horizontal movement cylinder C1 to slide table S. Positioned above. At this time, the head side (upstream side) of the moved unit tofu B shakes or moves. However, if the blades b and c of the suspension body 40 are moved upstream, the shaking is prevented and the head position Is aligned with the corresponding position of the packaging pack P. Note that the contact between the blade b and the tofu B may be released, but it is preferable that the blade b is kept slightly away from the unit tofu B and also serves as a drop guide means. Therefore, when the slide table S is pulled out (retracted) in this alignment state, the drop guide means comes into contact with the upstream side surface of the positioning blade c and each downstream side surface of the tofu B (four lines from the top side). (Fig. 3 (e) (f) (g)). Many tofu B falls in the horizontal state in the corresponding packaging pack P prepared under the slide table S. When packing is completed, the original standby state is restored.

(Third embodiment)
FIG. 4 shows a third embodiment, in which a suspension driving mechanism 40A having a large number of pushing blades b and a comb-shaped suspension body 40B having a large number of positioning blades c are separately configured. The horizontal moving cylinder C1 and the vertical moving cylinder C3 are driven as drive sources. The extruding blade b moves the tofu B so as to extrude it onto the slide table S. The slide table S is a one-side opening / closing method, but may be the both-side opening / closing method.
The comb-shaped suspended body 40A and the comb-shaped suspended body 40B of the present embodiment are different from the above-described driving means in that they have a comb shape without the blades b and c on the front end side. The extrusion blade b and the positioning blade c are driven in synchronism with the conveying direction of the unit tofu B, or are driven in synchronism to drive in the front-rear direction. have. Therefore, even when both blades b and c operate separately in the front-rear direction (FIG. 4), both blades b and c are each provided with a lift drive device that moves up and down so that they do not interfere with each other. The blades b and c are moved up or down at the same time or individually according to the operation, and the tofu group B is extruded all at once and packed together.
After the comb-shaped suspension body 40A and the comb-shaped suspension body 40B deliver the unit tofu B, the comb-shaped suspension body 40A returns to the original position (on the conveyor 10), and the next Preparation for extruding tofu B begins. The other comb-shaped suspension body 40B is used for alignment when a large amount of unit tofu B to be packed is dropped and stored in the packaging pack P, that is, for alignment of the top side of the unit tofu B. The position is aligned with the position of the packaging pack P conveyed by the packaging pack conveying device 20. In the present embodiment, cutting with the blades b and c is not performed.

Next, the packing operation of the tofu B of this embodiment will be described.
The tofu B cut to a predetermined size on the conveyor 10 is in an arrayed state with a certain matrix interval so as to match the packaging pack P in which a predetermined number is arranged in the width direction (and the traveling direction) of the conveyor 10. It is conveyed sequentially as unit tofu B. The drive mechanism 40 performs a standby operation until the first tofu B1 reaches the terminal end of the conveyor 10 (FIGS. 4A and 4B).

When the horizontal moving cylinder C1 moves + after the suspension body 40 is completely lowered, the comb-shaped suspension body 40 is horizontally moved so as to push out the tofu B. That is, by driving a large number of extrusion blades b, the unit tofu B in 4 rows and 7 columns is simultaneously moved toward the slide table S in a short time (FIGS. 4B and 4C).
The pushing blade b moves horizontally in the downstream direction while maintaining the state of four rows of tofu with the horizontal movement of the traveling vehicle 11a, and is positioned on the slide table S by being regulated by the stroke of the horizontal movement cylinder C1. . During this time, the push-up mechanism 23 of the packaging pack transport device 20 moves the pusher cylinder C7 to + to raise the packaging pack P in 4 rows and 7 rows located under the slide tables S1 and S2 to just below the slide table S. Waiting.

  Next, the horizontal moving cylinder Cb operates-and is pulled out to the slide table S on which the tofu B is placed. When the slide table S is retracted, the tofu B is guided and dropped as drop guide means in a state where it is in contact with the downstream side surface of the positioning blade c and each upstream side surface of the tofu B (FIGS. 4D and 4E). f) (g) (h)). Many tofu B falls in the horizontal state in the corresponding packaging pack P prepared under the slide table S.

(Fourth embodiment)
FIG. 5A shows the fourth embodiment, and shows a state where the tofu B is crossed so as to pass from the comb-shaped suspension body 40A to the comb-shaped suspension body 40B. By delivering in this way, the contact with the unit tofu B is once released from the blade, and the positioning by the positioning blade c becomes easy. FIG. 5B is an example in which only the positioning blade is used as a drop guide means and the extrusion blade b is brought into contact with the upper end of the unit tofu B and guided into the packaging pack. . In this way, when the slide table S, which will be described later, is tilted by the tilt mechanism Sk1, the blades can be packed without being in the way. The positioning blade c can also be guided to the packaging pack in a state where only the upper end of the tofu B is in contact. The comb-shaped suspension body 40A and the comb-shaped suspension body 40B in FIG. 5B are different from the above-described driving means in that they have a comb shape without the blades b and c on the front end side. In the suspension drive mechanisms 40A and 40B of the present embodiment, the extrusion blade b and the positioning blade c are driven synchronously or driven synchronously with respect to the tofu B conveyance direction. , Has drive control to operate in the front-rear direction.

(Fifth embodiment)
FIG. 6 shows a fifth embodiment, which is an embodiment in which an extrusion blade b and a positioning blade c are moved up and down by a cylinder C4 on a comb-shaped suspension body 40C as a driving mechanism. That is, a large number of alternately pushing blades b and positioning blades c are moved up and down uniformly.
Therefore, either the extrusion blade b or the positioning blade c can be used as a packing drop guiding means, and the packing dropping guide can be operated even if both are used to guide from two directions. It is easy to operate as a means.

(Sixth embodiment)
FIG. 7 shows a sixth embodiment, in which the slide table S is divided into a plurality for each one and includes an inclination mechanism Sk1. That is, the slide table S is provided with an inclination mechanism Sk1 for inclining and storing the packaging pack P conveyed from the horizontal posture by the packaging pack conveying device 20, and each of the slide tables S1 and S2 includes Inclined by the tilt mechanism Sk1 while retracting.
When the slide tables S1 and S2 are tilted and stored by the tilting mechanism Sk1, if they are packed with the tofu B sandwiched between them, it becomes an obstacle to store the tilt table obliquely. In the present embodiment, when positioning the front side of the tofu B, the pushing blade b is separated from the tofu, and only the positioning blade c is used as a drop guide means along the tofu. Even when the tilt mechanism Sk1 for tilting the slide tables S1 and S2 is employed, it is possible to avoid a situation in which the blade b interferes with the packing.

  FIG. 8 (a) is another example of the present embodiment, and illustrates a tilt mechanism Sk2 that is tilted by retracting the slide table S so as to draw an arc obliquely upward. (B) has a mechanism in which the slide tables S1 and S2 are divided and retracted so as to draw an arc obliquely upward. Even when such an inclination mechanism Sk2 is employed, it is possible to avoid a situation where the blade interferes with packing. In the sixth embodiment and the present embodiment, it is preferable that the slide table S has a split mold or a shape in which the lower side is cut into an uneven shape so that the convex portion can be inserted into the packaging pack.

As described above, in the present embodiment, the description has been given by using the packaging pack conveying device 20 of the two-column simultaneous conveyance. However, the present invention is not limited to this, and how many lines can be obtained by combining one line in a plurality of lines. It is possible to correspond to the tofu of the row, and it is possible to correspond to the packing of the present invention by using a packaging pack conveying device having three or more rows.
In addition, the dropping guide means is made of fluorine coating, polishing (buffing, electrolytic polishing, etc.), embossing, etc. on the member that comes into contact with tofu and the slide table that slides tofu to drop the tofu. It is preferable to use a surface material that reduces the frictional resistance of the tofu, makes the tofu slip easily, and makes it difficult for tofu to adhere. It is also preferable to dispose fresh water sprinklers and spring water devices, and devices for spraying edible oil or edible emulsion for lubrication as necessary. Further, a fixed second drop guide means for guiding to the packaging pack may be provided directly under the slide table. For example, the lower part is narrower than the inside size of the packaging pack, and the upper part is a small, square hopper or chute that is widely formed to receive falling tofu.
