Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a method and apparatus for automatically sealing and packaging tofu and other very soft and fragile articles while maintaining sterilization or sterility.

Conventional technology and its problems At tofu manufacturing plants, when tofu is continuously manufactured into a predetermined shape and packaged one by one, the tofu is soft and easily broken, so the tofu is soaked in water and then individually packed by workers. Take the paper out of the water by hand, being careful not to break it, put it into a pack with the other hand, and then feed it to an automatic packaging machine using a conveyor or other feeding means or directly by hand. Bean fraud packs are packaged in thin films such as polyethylene V-film and shipped.These 1-bag packs of beans are indispensable for manufacturers who produce large quantities of beans and distribute them to supermarkets and retail stores. It is a colander work.

Because tofu is soft and very fragile, it is impossible to automatically or mechanically 33 curd or package it. For this reason, tofu is soaked in water.
Workers must be careful not to break the dough while frying and packaging it, which is inefficient and requires a lot of manpower in the manufacturing process.

Furthermore, if the temperature of the water is low enough for an operator to squeeze the tofu by hand, bacteria will easily adhere to the tofu, and there is a risk that this bacteria will grow after the tofu is sealed and packaged.

In view of this, the present invention provides a method for solving the problem of achieving more hygienic production by carrying out the process from tofu production to sealed packaging in an aseptic state. The first conveying means for conveying beans in the hot water tank is in contact with the terminal end of this conveying means and is driven faster than the seventh conveying means, and is transferred from the first conveying means and performs a packing operation. A second conveying means is arranged to stand by in synchronization, first and second stoppers are provided in front and rear positions of the second conveying means so as to be able to rise and fall;
A pack elevating device adjacent to the stopper that moves up and down between the pack supply position and the conveyance line to supply packaging packs one by one; and a pouring nozzle located below the pack elevating device that pours metal into the delivered packs. and a pack holding guide device which can be raised and lowered to prevent the pack placed on the table from floating at the table lowering position of the pack lifting device and to act as a guide when the tofu pack is moved in. On the opposite side, there is a pack holding guide that holds down the protruding chips (on the end surface of the pack) when putting tofu in, and also acts as a stopper. The produced tofu is transported one by one through the hot water tank without being exposed to air, and the tofu is transported one by one to the second transport line (which is driven) and the position where it is fed into the pack a little faster than the first transport line, and the tofu is transported one by one to the stopper. After feeding it in operation and entering it one by one,
This pack is lifted out of the hot water and sealed. This provides an automatic packaging method and device that is more hygienic and has a longer shelf life without impairing taste.

Example Next, the present invention will be explained based on embodiments shown in the drawings.

1 is a hot water tank, which is filled with intestines that have an appropriate temperature so that bacteria will not grow on the tofu and will not spoil the taste.
In addition to heating and circulating the tofu to keep it at an appropriate temperature as necessary, a conveying device 2 such as a net conveyor is installed in the bath 1, and the tofu is manufactured to the required size using a tofu manufacturing machine (not shown). When the tofu is put into the hot water tank, it is conveyed through the hot water in the hot water tank l by the conveying device 2. This tank is filled with hot water immediately after the tofu is produced, or at a temperature suitable for maintaining sterile conditions to prevent the growth of bacteria, and is designed to maintain a cool temperature. A second conveying device 3 is adjacent to the terminal end of this conveying device 2 and is continuous with this conveying device and supplies to the packing position.
The tofu is transferred from the conveying device 2 to the second conveying device 3 in hot water and conveyed. This second conveyance device 3 may be a short belt conveyor type or a roller conveyor in which a large number of rollers are arranged in parallel at a required pitch and driven in the same direction, and its driving speed is set higher than that of the conveyance device 2. And this first transport device'! 12 and the second conveyance device 3, a vJ/s)7 par 4 is disposed such that it can be raised and lowered by a lifting device 1t6. The beans and beans transported by the first transport device 2 are lined up at the same time, and in the case of packaging them into multiple packs, they are placed on the alignment board (
(not shown) is disposed on the first conveyance device. At this time, if the alignment plates are arranged in parallel so that the tip, that is, the tofu input side is wide, and the back part on the second conveyance device side is narrow, even if the tofu that is conveyed in the tank by the conveyance device 2 is misaligned, When the tofu reaches the tip of the arranging plate, the directions are aligned automatically or by the operator between the arranging plates, so that the tofu can enter each packaging position one by one. 3. In this position, maintain a position that allows you to enter the puck.

Φ Also, a second stopper 5 is disposed at the tip of the second conveyance device 3 so as to be able to rise and fall freely, and the tofu transferred to the second conveyance device comes into contact with the second stopper 5, The conveying device is always driven and stopped.

The second stopper 5 has two positions: a lowered position where the tofu on the second conveying device is stopped even if the device 3 is continuously driven, and a raised position where the tofu enters the next pack submerged in hot water. A lifting device 6 such as a cylinder for lifting and lowering is provided.

A pack lifting device 7 is disposed adjacent to the second stopper 5. This consists of an elevator 71 such as a cylinder and a tape/I/72 that receives the pack, and it is used to press one pack P, which is fed out from a pack feeder placed nine times above the tank, onto the tape)v72. Masui d and Yuwauchi's second
The tapered liner is made to move up and down between the lowered positions at the same height as the conveyor line. When the second stopper 5 is raised when the table 72 is in the lowered position, the tofu on the second feeding device 3 is driven out and enters the pack on the table 72. At this time, to ensure that the tofu enters the pack from above the second conveying device, an extruder mechanism 8 is provided so that the extruder groove 8 is moved from the second conveying device to the table. , consists of a push plate 82 protruding from the tip of the tofu and pushing it in contact with the rear end of the tofu, and a guide 83 that reliably moves this push plate 82 from the second conveyance device to the pack side. Due to this action, the push plate 82 is located above the tofu on the device 3 above the starting end side (first stopper side) of the second conveyance Wiita, so that it does not obstruct the tofu from entering the first conveyance device.

The pack feeder 9 stores a large number of stacked packs P and automatically feeds out one pack at a time from the bottom of the pack P, and is a conventionally used one that can be used for lifting and lowering the packs. Lifting and lowering of device 7 I! It is synchronized with 71 works. When the table 72 rises and stops directly below the pack feeder, the pack feeder 9 is fed out, the roller 9a is pivoted, and the reap pack P is moved from the lower stage side. Extruded Tefu Susumushi 7
2. Feed by falling above.

Simultaneously with this or immediately thereafter, molten metal is poured into the upper 'f19 position (this pack I).

This is because there is no problem in dropping and feeding the pack P onto the table 72 from the supply machine, and/or two or more pouring nozzles 10 are provided at positions where pouring into the pack can be reliably performed.
tape tv;? j';
．． Make sure that the inside of the tank is filled with hot water. The temperature of pouring hot water into this pack should be the same as or slightly higher than the temperature of the water inside the tank. When the pack sinks below the hot water level together with the table due to its own weight and the operation of the elevator, the pack also naturally sinks under the hot water tank, so that the line is approximately the same as the second conveying device line.

At this time, in order to ensure that the pack sinks and does not surface, and to ensure that the beans 13 enter the pack,
A pack holding guide 11 is provided. This is an L-shaped integral body consisting of a horizontal guide piece 11a that holds down the upper end trunk Pa of a pack placed on a table, and a guide stopper piece 11b that extends t above the guide piece. The left and right guide pieces are connected to each other and are used as pack holding guides by a driving device 11c such as a cylinder.

Therefore, immediately after the table passes, this pack holding guide descends and the %Pa of the pack on the table is measured by the guide piece 11.
Press from above with a to completely prevent the pack from floating. At the same time, the back presser guide 12, which is located in the opposite direction between the second conveyance device and the table 72, is pushed out by its cylinder 12a, and the end side of the pack is pushed out! IL now press the pack presser guide 12 and the guide piece 1ll).

11b, the illusion of the pack is held down on three sides except for the second transport device side, and when the second stopper is raised, the second
The tofu sent out by the conveying device is guided by the guide piece 11b of the guide 12 and is ensured to enter the pack.

Note that the first stopper 4 is lowered when tofu is stocked on the second carrying device, stopping the supply from the first carrying device, and indicating that the top of the second carrying device is empty. When detected, this first stopper is released and the next tofu is allowed to enter. The seventh and second conveying devices are driven continuously, with the second being driven at a slightly faster speed than the first, and the first, second and stoppers 4 and 5 are operated, and the pack holding guides 11 and 12 are operated. advancement and retreat, advancement and retreat of the extrusion mechanism 8,
The lifting, lowering, and holding operations of the pack lifting device 7, the supply of the pack, and the pouring of molten metal into the pack are all performed in the same week.

Also, when the tofu is packed into the pack P and the tape /L/72 is raised, in response to this signal, the extruder 13 arranged on the side of this position moves the pack from the raised table to the conveyor leading to the packaging machine. 14 and transfer it to the top. Then, when this tofu bag is transferred to the conveyor and the extruder is stacked again, the next pack is supplied onto the table from pack supply →. In this way, tofu is automatically and continuously packaged under aseptic conditions. It is preferable to stop pouring the hot water when the pack containing the tofu rises with the table.

Effects of the Invention According to the present invention, manufactured tofu is transported through a bath having a temperature that maintains a sterile state without impairing taste, and in this lined state, the tofu is sequentially placed in the pack starting from the front row. When the pack descends into the hot water into which hot water is poured, the tofu that has been waiting in the hot water is sent out into the descending pack. Therefore, even fragile and soft tofu can be reliably and automatically packed without breaking the tofu and without making the young seedlings adhere to the tofu, which has the effect of saving labor and making production more hygienic.
