Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a bag screw packaging device that can screw and heat-seal bags filled with mushrooms such as Enoki mushrooms. be.

[Prior art] Conventionally, this type of bag screw-in packaging device was developed in 1982.
Publication No. 35307 is known.

In this conventional structure, a screwing mechanism is arranged opposite to the surplus part of a bag made of polyethylene, vinyl, etc. filled with stuffed materials such as Enoki mushrooms, and the surplus part of the bag is screwed in by the screwing mechanism, and the heater body The bag is configured to be packaged by heat-sealing the screw-in portion of the excess portion of the bag.

[Problem to be solved by the invention] However, in the case of the conventional structure described above, when the excess portion of the bag is screwed in by the screwing mechanism, the bag may move toward the screwing mechanism side due to the screwing operation, and as a result, the bag may move toward the screwing mechanism side. This has the disadvantage that the heater body may come into contact with the bag, causing damage to the bag.

[Means for solving the problem] The purpose of the present invention is to solve these inconveniences. In the product in which the excess portion of the bag is screwed in by the screwing mechanism, and the screwed-in portion of the excess portion of the bag is sandwiched between a pair of heater bodies and heat-sealed and packaged, the pair of heater bodies and the lateral side of the bag are A bag screw-in packaging device comprising a pair of position regulating members located between the heater body and extending along the moving direction of the heater body to prevent the bag from moving toward the screw-in mechanism. It is in.

[Function] The position regulating members are arranged as a pair between the pair of heater bodies and the side of the bag and extend along the moving direction of the heater bodies, and the position regulating members prevent the bag from twisting. This prevents the bag from moving toward the filling mechanism and prevents the bag from being damaged by the heater body.

[Example] Figures 1 to 4 show an example in which the present invention is applied to a bagging and packaging machine for Enoki mushrooms, and 1 is a fusible bag made of polyethylene, vinyl, etc., and in this case, Enoki mushrooms. Bags 1 filled with stuffed material W are sequentially sent onto a transfer table 2 by a transfer mechanism (not shown).

3 is a screw mechanism in which a support bracket 5 is erected on a machine base 4, a bearing body 6 is provided on the support bracket 5, a rotary cylinder 7 is provided on the bearing body 6 so as to be rotatable by a bearing 8, A sprocket 9 is fixed to one end of the rotating cylinder 7, and a holder plate 10 is fixed to the other end, and a pair of clamping members 11 are clamped and pivotally mounted between the holder plates 10 by pins 12, Rotating tube 7
A reciprocating rod 13 is provided inside the machine so as to be able to move forward and backward, and the end of the retracting rod 13 is connected via a rotary joint 14 to a rod 17 of a clamping cylinder 16 provided on a bracket 15 erected on the machine base 4. A rack 18 is formed at the tip of the rack 13, a gear 19 that can mesh with the rack 18 is formed on the pair of clamping members 11, a motor 20 is provided on the machine base 4, and a sprocket 21 is fixed to the main shaft of the motor 20. A chain 22 is wound around the sprocket 9.

Reference numeral 23 denotes a heater body, which is disposed oppositely above and below the screwed-in portion of the surplus portion 1a of the bag 1 containing the stuffed material W, and is provided so as to be movable upwardly and downwardly toward and away from each other by a sealing mechanism (not shown).

Reference numeral 24 denotes a position regulating member, which is attached to the transfer table 2 and is formed so as to be able to face the shoulder portion 1b of the bag 1 that is generated when the bag 1 is twisted.

Since this embodiment has the above configuration, when the filled bag 1 is being transferred from the right side to the left side in FIG.
moves backward, the clamping member 11 closes and clamps the excess portion 1a of the bag 1 from the outside, and the motor 20 operates and the clamping member 11 rotates to close the bag 1 as shown in FIG. The surplus portion 1a of the bag 1 is screwed in, and the pair of upper and lower heater bodies 23 move toward each other to remove the surplus portion 1a of the bag 1.
After sandwiching and heat-sealing and packaging, the pair of heater bodies 23 move away from each other, and the sandwiching member 11 opens and twists due to the protruding movement of the rod 17.

Even if the bag 1 is to be moved toward the screw-in mechanism 3 when the bag 1 is screwed in, the position regulating member 24 prevents this movement, so that the heater body 23 comes into contact with the shoulder portion 1b other than the screw-in portion, causing the bag 1 to move toward the screw-in mechanism 3 side. The position regulating member 24 is arranged in a pair between the pair of heater bodies 23 and the side of the bag, and extends along the moving direction of the heater bodies 23. Therefore, it is possible to prevent the bag from being affected by the heat of the heater body 23, and damage to the bag 1 can be prevented.

In this case, as shown in FIG.
Since they are located above and below the surplus portion 1a of the bag 1, they have a good position regulating effect and also guide the folding and transferring operation of the surplus portion 1a of the bag 1.

[Effects of the invention] As described above, in the present invention, even if the bag is to be moved toward the vertical screwing mechanism, the position regulating member prevents the bag from moving, so that the heater body does not move toward the shoulder, etc. other than the screwing member. This position regulating member is arranged in a pair between the pair of heater bodies and the side of the bag, and extends along the moving direction of the heater bodies. Since this is provided, it is possible to prevent the bag from being affected by the heat of the heater body, and damage to the bag can be prevented.

As described above, the intended purpose can be fully achieved.
