DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for automatically packing frozen foods such as crab roe and hamburgers and various items stored in packaging boxes into packaging boxes.

Conventionally, when packing frozen foods and the like into packaging boxes, for example, the products flowing on a conveyor were manually packed into the boxes. However, this resulted in a large loss of time and caused problems in terms of work efficiency. In addition, it required a lot of manpower, which caused problems in terms of labor management and, in the case of food products, in terms of hygiene.

The present invention was developed as a result of various studies in view of the problems described above, and its purpose is to solve the above problems and provide a method for automatically and efficiently packaging products. It's about doing.

DETAILED DESCRIPTION OF THE INVENTION The method of the present invention will be described below with reference to the illustrated automatic boxing apparatus for frozen foods, which is one embodiment. A specific example of a boxed product is Korotsuke.

As shown in FIG. 1, reference numeral 1 denotes a pedestal, which is disposed so as to intersect with a conveyor 2 on which a box for storing crotches is placed. Further, in front of the pedestal 1 in the longitudinal direction, an alignment conveyor B is arranged at the same height as the pedestal 1. The alignment conveyor B is used to regularly align the crotches 3 to the automatic boxing device A and carry them out.

Loop-shaped chains 4, 4' (one not shown) are attached to the pedestal 1 in parallel to the left and right in the longitudinal direction. Specifically, large-diameter idler wheels 5, 5' (one not shown) are aligned on conveyor B.
It is rotatably attached via a shaft 6 near the left and right upper portions of the side frame 1. In addition, drive chain wheels 7 and 7' are connected to the pedestal 1 through a shaft 8 near the upper part of the pedestal 1 which faces the pedestal 1.
are attached to the left and right sides of the Furthermore, a small idler chain wheel 9 for tension is provided diagonally below the left and right idler chain wheels 5, 5' and drive chain wheels 7, 7', respectively.
9', 10, 10' (one not shown) are shafts 11, 1
2. The loop-shaped chains 4, 4' are connected to the above-mentioned idle chain wheels 5, 5', drive chain wheels 7, 7', and small idle chain wheels 9, 9', 10, 10' provided on the left and right sides of the frame 1. are installed on each side.
Further, a chain wheel 13 attached to one of the drive chain wheels 7, 7' and an electric motor 14 which is a power source provided at the bottom of the pedestal 1 are connected by a drive chain 16 via a transmission and a chain wheel 15. There is. By driving the electric motor 14, the loop chains 4 and 4' stretched in parallel on the left and right sides of the pedestal 1 can be simultaneously rotated.

The left and right chains 4 and 4' are shown in Figures 2 and 3.
As shown in the figure, clamping tools 17 of an embodiment for clamping sheet bodies C, which will be described later, are successively attached at equal intervals. Therefore, the clamping tool 17 will be explained in detail. The clamping tool 17 consists of a square-shaped base plate 18, support plates 19, 19, a spring 20, a clamping piece 21, and a shaft 22. The square-shaped base plate 18 has notched holes 23, 23 on both sides thereof.
23 to both link plates 25, 25 of chain 4
The pin 25 is inserted into the pin 26 protruding from the pin 25.
Both ends of the chain 4 are caulked and fixed to the chain 4.

Further, the support plates 19, 19 are for supporting the clamping piece 21, and are erected at the center of the upper surface of the base plate 18. And on the support plates 19, 19,
A clamping piece 21 is attached via a shaft 22.
The clamping piece 21 is a flat plate having a locking part 21' at the center and consisting of a curved front end 27 for clamping the sheet C, and a slightly bent rear end 28. The tip end 27 of the clamping piece 21 is normally attached to the base plate 18 by the spring 20 inserted into the shaft 22.
is in strong contact with the upper surface 24 of. Also, the tip 2
7 faces the tip end portion 27' of the clamping piece of the clamping tool 17' attached to the opposing chains 4, 4'.
Note that the clamping tool 17 is attached to the chain 4 as shown in FIG.
Attach each roller 29 in sequence. It is also free to attach them at intervals of 2 to 3 pitches or several pitches.

Furthermore, as shown in FIG. 2 (one side is omitted), the upper and lower surfaces 31 of the guide frames 30 and 30' that support the left and right idler chain wheels 5 and 5' support the chain wheels 5 and 5'. Guide rods 32, 32' curved in a direction are attached at a width of two to three pitches or several pitches of the chains 4, 4' along the direction of rotation of the chains 4, 4'. By means of the guide rods 32, 32', the clamping pieces 2 of each clamping tool 17 attached to the loop-shaped chains 4, 4'
1 is forcibly held down by its rear end 28 when passing over the upper part of the floating chain wheels 5, 5', and its tip 27 rises upward against the force of the spring 20, temporarily causing the base From the top surface 24 of the plate 18 to the tip 27
leaves. Thereafter, the chains 4, 4' meshed with the upper portions of the idle chain wheels 5, 5' gradually move toward the guide rods 32, 32' at a position 2 to 3 pitches or several pitches ahead of the chain wheels 5, 5'. The rear end portion 28 is separated from the rear end portion 28, and the tip portion 27 of the clamping piece 21 comes into contact with the upper surface 24 of the base plate 18 again due to the elastic bias of the spring 20.

During this series of operations, the tips 2 of the clamping pieces 21 of the clamping tools 17 provided on the left and right chains 4
7 and the upper surface 24 of the base plate 18, the sheet body C
The end portion 27 is inserted by hand when the tip portion 27 is separated from the upper surface 24. After that, the chains 4, 4' are rotated, the guide rods 32, 32' and the clamping tool 1 are rotated.
The sheet body C is successively clamped by the action of 7 and moves forward as the chain rotates.
The sheet body C functions as a conveyor belt.

Next, a sheet C made of vinyl or the like is wound into a roll and is detachably attached to a bracket 34 attached to the alignment conveyor B side of the pedestal 1 as shown in FIG. This sheet body C is held by the clamping tools 17, and one end is rolled out to function as a conveyor belt as described above. It is engaged with an idling roller 36 provided on the left and right chains 4, and is clamped by a clamping tool 17 attached to the left and right chains 4 that operate. Further, the level of the sheet body C as a conveyor belt is the same as the upper surface level of the alignment conveyor B, but is slightly lower, so that the crotches 3 transferred from the alignment conveyor B can be smoothly transferred to the sheet body C.
I'm starting to be able to move on.

In addition, the above-mentioned rolled sheet body C is as follows:
It can be attached to the alignment conveyor side or placed on the floor. Further, the sheet body C is not limited to vinyl material, but may also be paper, cloth, or the like. Furthermore, the sheet body C
In addition to being wound into a roll, it may be a flat plate that is continuously folded and layered to a certain width; in short, it may be anything that can be continuously fed as a conveyor belt and cut.

Next, a sensor 37 is attached to the upper part of the pedestal 1. The sensor 37 detects the tip of the block 3 that is transferred to the sheet body C as a conveyor belt and moves with the rotation of the left and right chains 4, and at that position, the tip of the block 3 is moved. It works to stop rotation. Therefore, the sensor 37 is set at a position slightly outside the end of the box 39 on the side opposite to the alignment conveyor, which is placed on the conveyor 2 which is disposed above and below the pedestal 1 so as to intersect with the pedestal 1. It is located at the top. Further, in this embodiment, a phototube is used as the sensor 37, but any sensor such as a limit switch ultrasonic detector or the like that can stop the chain at a predetermined position may be used. Furthermore, the sensor 37
The installation position can be changed freely.

Further, 40 is a sheet cutter tool, and the cutter tool 40 is arranged so that the chain 4 stopped by the sensor 37, that is, the long sheet body C, can be stored in the box body 39 together with the crochet 3. It cuts the sheet body C into a uniform width, and is provided above the sheet body C. The cutter tool 40 cuts the sheet C in the width direction by instantly moving an elongated blade 41 slightly curved downward up and down with a pneumatic cylinder 42. Incidentally, although the pneumatic cylinder is a liquid pressure cylinder, the blade 41 may be mechanically operated by a link mechanism or the like.

Then, the sheet body portion cut by the sheet cutter tool 40, that is, the sheet body piece 43, is held at both ends by the clamping tools 17 with the corotoke 3 placed thereon, and is placed in the box body 39 on the conveyor 2. It is located above. In this state, the clamps 17 holding the sheet body pieces 43 are simultaneously and instantaneously released by the clamp releasing means to allow the blocks 3 and the sheet body pieces 43 to fall naturally. , the block 3 and the sheet body piece 43 of the box body 39 on the conveyor 2 are stored. Regarding natural fall in this case, in the case of a product such as Korotsuke 3, it is possible to sufficiently store it in the box 39 without it coming apart without pressing the Korotsuke 3 on the sheet body piece 43 from above and packing it into the box 39. .

Therefore, the clamping tool opening means of the above-mentioned embodiment is
This will be explained in detail based on the drawings.

As this means, a clamping piece actuator 48 is slidably provided on the piston rod 46 of the pneumatic cylinder 45. The operating tool 48 is a rectangular flat plate as a whole, and is provided on the left and right sides of the pedestal 1, and both ends located on the chain 4 side are bent downward at a right angle. The tip portions 51 of both bent ends come into contact with the rear end portion 28 of the aforementioned clamping piece 21 during operation. A hole 49 through which the piston rod 46 is inserted is bored in the center of the actuator 48, and a bush 50 is fitted into the hole 49 so that the actuator 48 can slide on the outer surface of the piston rod 46. When the cylinder 45 is operated, the actuating tool 4
8 slides the piston rod 46 of the cylinder 45 up and down on the outer surface.

That is, when the cylinder 45 is actuated and the piston rod 46 is lowered, the actuator 48 is also moved downwards.
6 and descends without sliding. The tip end 51 of the actuating tool 48 is connected to the clamping tool 1 of the left and right chain 4.
7, and the actuating tool 48 does not slide upward on the outer surface of the rod 46, but as the rod 46 descends, it moves against the spring 20 of the clamping tool 17 to hold the clamping piece. Press 21. Due to this action, the tip portion 27 of the clamping piece 21 separates from the upper surface 24 of the base 18. That is, the left and right clamping tools 17 open the sheet body piece 43.

When this operation is completed, the rod 46 rises, and the actuating tool 48 also rises together with the rod 46, separating from the rear end 28 of the clamping piece 21 of the clamping tool 17 attached to the left and right chain 4, and leaving the tip of the clamping piece 21. 27 comes into contact with the upper surface 24 of the base plate 18 again due to the resilient force of the spring 20. Of course, the series of operations described above by the clamp release means are performed instantaneously. Then, chain 4 rotates again. Further, the box 39 filled with the crotches 3 is also transferred, and the next empty box 39 on the conveyor 2 is set at the position where the crotches 3 and the sheet pieces 43 fall. Then, by repeating the described operation, the crotches 3 are automatically packed into the box body 39 one after another. In addition, in the case of this embodiment, the sheet body piece 4
3 is made slightly wider than the width of the box body 39, so that both ends of the sheet body piece 43 are rolled up inside the box body, and in the case of a product containing moisture such as Korotsuke 3, moisture is removed. It has the advantage of preventing water from penetrating into the box body.

Note that the gripping tool and the gripping tool release means are not limited to the above embodiments.

As described above, the present invention provides the clamping tools 17 attached to the loop-shaped chains 4, 4' which are arranged parallel to the left and right sides of the pedestal 1 and rotated by the power from the power source.
, the both ends of the unwound sheet body C are successively clamped, and as the chains 4 and 4' rotate, the clamped sheet body C is loaded with the product transferred from the previous process and moved. The loop-shaped chains 4, 4' are stopped at a set position by the sensor 37, and the sheet body C on which the product is placed is cut into appropriate dimensions by the sheet cutter tool 40, and the cut sheet body piece 43 The product on the sheet body piece and the sheet body piece 43 are released by the clamp release means, and the product on the sheet body piece and the sheet body piece 43 are allowed to fall naturally to the box body 39 on the conveyor 38, which is automatically positioned at the falling position. This is an automatic boxing method for frozen foods, etc., in which the products placed on the sheet body C can be automatically and sequentially boxed together with the cut sheet pieces 43, so that the intended purpose can be effectively achieved. This makes it possible to pack products very efficiently. Furthermore, during work, for example, in the case of boxed products such as frozen foods, the worker's hands do not touch the food, making it very hygienic.

Furthermore, since the products can be automatically packed in boxes by laying out sheets cut to appropriate dimensions and arranging them in a regular manner, the process is no different from the conventional boxing process that was done manually.
It is possible to pack products into boxes at high speed. As described above, the present invention is an invention that has many effects.
