Incidentally, 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 the direction of rotation of the chains 4, 4'
It is attached with a width of ~3 pitches or several pitches. By means of the guide rods 32, 32', the clamping pieces 21 of each clamping tool 17 attached to the loop-shaped chains 4, 4
When passing over the upper part of the floating chain wheels 5, 5', the rear end part 28 is forcibly held down, and the tip part 27 rises upward against the force of the spring 20, temporarily causing the base plate to collapse. The tip 27 is separated from the upper surface 24 of 18. Thereafter, the chains 4, 4' meshed with the upper parts 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
The tip end 27 of the clamping piece 21 comes into contact with the upper surface 24 of the base plate 18 again due to the resilient force 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
When the tip 27 is separated from the upper surface 24, insert it. 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 or slightly lower than the upper surface level of the alignment conveyor B, so that the frozen food 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 leading end of the frozen food 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 the chain 4 is moved at that position. The function is to stop the rotation of the 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 that can stop the chain at a predetermined position, such as a limit switch or an ultrasonic detector, may be used. Furthermore, sensor 3
The mounting position of 7 can be changed freely.

Further, 40 is a sheet cutter tool, and the cutter tool 40 cuts the chain 4 stopped by the sensor 37, that is, the long sheet body C into the frozen food 3.
The sheet body C is cut into a certain width so that it can be stored in the box body 39, and is provided above the sheet body C. Then, the cutter tool 40 instantly moves the elongated blade 41 slightly curved downward up and down with the pneumatic cylinder 42 to cut the sheet body C.
is cut in the width direction. 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, with the frozen food 3 placed thereon, is held at both ends by the clamping tools 17, and placed in the box body 39 on the conveyor 2. It is located above. The frozen food 3 and the sheet body piece 43 in this state are instantly pushed downward by the pressing tool 44 provided above and the clamp release means, and the conveyor 2
The frozen food 3 and the sheet body piece 43 are inside the upper box body 39.
Pack it.

Therefore, this pressing tool 44 and the clamping tool release means will be specifically explained based on FIG. 4. The pressing tool 44 mainly consists of a pneumatic cylinder 45, and a piston rod 46 47 is attached to the tip of the cylinder 45. The pressing plate 47 is
It is a thin flat plate with a rectangular or square shape. Alternatively, a flat plate whose dimensions can be adjusted in the longitudinal direction of the sheet may be used. The pressing plate 47 is connected to the cylinder 45
When activated, the frozen food 3 on the sheet piece 43 comes into contact with the frozen food 3, and in this state is pressed up to the box 39 located below.

Next, a description will be given of the clamp release means.As the means, a clamp piece actuator 48 is provided so that the pressing tool 44 can be slid on a piston rod 46 above the pressing plate 47. 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 pressing tool 44 is operated, the operating tool 48 slides up and down on the outer surface of the piston rod 46 of the pressing tool 44. That is, when the pressing tool 44 is actuated and the piston rod 46 is lowered, the actuating tool 48
The rod 46 also descends without sliding.
The tip end 51 of the actuating tool 48 connects the left and right chain 4.
The actuator 48 contacts the rear end 28 of the clamping piece 21 of the clamping tool 17, and the actuating tool 48 resists the spring 20 of the clamping tool 17 as the rod 46 descends without sliding upward on the outer surface of the rod 46. and press the clamping piece 21. Due to this action, the tip 27 of the clamping piece 21
away from the upper surface 24 of the base plate 18. That is, the left and right clamping tools 17 open the sheet body piece 43. And as Rod 46 continues to descend,
The tip end 51 of the actuating tool 48 is connected to the rear end 2 of the clamping piece 21.
8, the rear end portion 28 is in contact with the base plate 1.
As the rod 46 descends at 8, the actuator 48 slides on the outer surface of the rod 46 by means of the bush 50.

Further, the pressing plate 47 attached to the rod 46 comes into contact with the frozen food 3 on the sheet body piece 43 at the same time as the clamping tool 17 is released by the operating tool 48, and the frozen food 3 placed regularly falls down at a faster speed. Quickly press the frozen food 3 and the released sheet body piece 43 downward. Then, the frozen food 3 is packed with the sheet pieces 43 spread inside the box 39 on the conveyor located below.

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 pressing tool 44 and the clamping tool release means are performed instantaneously.
Then, chain 4 rotates again. Further, the box 39 filled with the frozen food 3 is set to the next empty box 39 on the conveyor 2. Then, by repeating the above-mentioned operations, the frozen foods 3 are automatically packed into the box body 39 one after another. In addition, in this embodiment, the width of the sheet piece 43 is slightly wider than the width of the box body 39, so both ends of the sheet piece 43 are rolled up inside the box body, and the frozen food In the case of products containing moisture such as No. 3, there is an advantage in that it prevents moisture from penetrating into the box.

As described above, the present invention includes a clamping tool attached to a loop-shaped chain that rotates by power from a power source disposed parallel to the left and right sides of a pedestal, and a loop-shaped chain that is clamped at both ends by the clamping tool. a sheet body provided to move the upper part of the gantry with the product placed thereon as the chain rotates, and a sensor that stops the loop-shaped chain, which moves with the product placed on the sandwiched sheet body, at a set position; A sheet cutter tool that cuts the sheet body on which the product is placed into an appropriate size, a pressing tool that instantly pushes the cut sheet body piece downward together with the product, and a pressing tool that pushes out the sheet body piece and simultaneously pushes out the sheet body piece. It consists of a means for releasing the clamping tool, and a conveyor on which a box body for storing the product pushed out downward and the sheet body piece is placed, and the product placed on the sheet body is cut. Since the structure is such that the product can be automatically and sequentially packed together with the sheet pieces, the intended purpose can be effectively achieved and the product can be packed very efficiently. Furthermore, during work, for example, in the case of boxed products such as frozen foods, the operator's hands do not touch the food, making it very hygienic. Furthermore, the products can be automatically packed in boxes by laying out sheets cut to the appropriate size and arranging them in a regular manner, which is no different from the conventional method of packing products manually, and allows products to be packed at high speed. Able to perform box packing work. As described above, the present invention is an invention that has many effects.
