Description

{AUTOMATIC BINDING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a food packaging apparatus, and more particularly to a binding apparatus for binding a tie or a band to a non-formed food packaging material made of a material such as a vinyl or film.

BACKGROUND ART [0002] Generally, a bag-shaped packaging material such as a vinyl or a film is usefully used as various food packaging materials due to its low cost, excellent sealing property and airtightness. For example, most foods containing liquids such as kimchi, oysters, and salted fish are packed using plastic bags, and the entrance to the plastic bag filled with the contents is formed by a thermocompression method, a binding cord with a built-in wire, As shown in Fig.

Korean Patent Laid-Open Publication No. 2008-0097783 (published on Nov. 6, 2008) discloses an opening binding clip for a packaging material and a binding apparatus using the clip. Such clips and binding devices can provide robust and high sealing performance without thermocompression of the encapsulated food packaging material.

On the other hand, in packaging the fermented food such as kimchi with the bag-type packaging material, the shape of the packaging unit is constantly maintained during distribution along with the pressure change inside the packaging material due to the gas generated by the fermentation of the packaged food during circulation To reduce logistics costs. By covering the capacity smaller than the actual acceptable capacity of the packaging material and vacuuming the inside, the change in the internal pressure due to the fermentation of the food during distribution can be accommodated in the entire capacity of the packaging material. However, since the capacity of the fermented food is smaller than the capacity of the packaging material, the food may flow in the packaging material. This causes the shape of each unit package to change, which can lead to an increase in the loading volume in mass distribution. This can lead to an increase in logistics costs.

Therefore, in the packaging of the fermented food, it is possible to restrict the flow of the contents in the packaging material by binding the band or tie together with the sealed package using the clip.

However, there is a problem that the binding of the band or the tie is made by the manual operation of the operator and the productivity is lowered. In addition, there is a disadvantage in that, depending on the skill level of the worker, and even when the same worker performs the binding work, the variation in the production rate is large depending on the fatigue.

Accordingly, the present invention is intended to provide a binding apparatus for a food packaging material capable of automating the binding of a binding member such as a band or a tie through various embodiments.

The present invention also provides a binding apparatus for a food packaging material capable of improving the fatigue of an operator and improving productivity by automating the binding of binding members such as bands and ties.

Therefore, the automatic binding apparatus of the food packaging material according to the embodiments of the present invention comprises: a conveyor for conveying the food packaging material from the insertion position to the binding position; A rotating device which rotates the food packaging material at least once in a binding position; And a binding device for binding the food packaging material tightened by the rotating device to a binding member.

According to one of the embodiments of the present invention, the food packaging material comprises: a receiving portion in which food is housed; And a tightening portion extending upward from the accommodating portion,

The binding device may bind the binding member around the tightening portion.

At this time, the automatic binding apparatus includes: a first guide member provided on the conveyor and extending from the feeding position; And a second guide member extending from an end of the first guide member to the binding position,

The first guide member guides the feeding of the food packaging material while facing the outer surface of the accommodating portion and the second guide member can guide the tightening portion to the binding position of the binding member.

The second guide member may include: a fixed guide member extending obliquely with respect to the conveying direction of the conveyor; And a rotatable guide member extending obliquely with respect to the conveying direction of the conveyor, wherein the fixed guide member and the rotatable guide member can respectively extend in a direction converging at the binding position.

When the food packaging material reaches the binding position, the rotatable guide member rotates to tightly fix the tightening portion to the binding apparatus.

According to another embodiment of the present invention, the rotating device can move up and down in the upper and lower directions at the upper portion of the binding device.

At this time, the rotating device includes: a rotary motor installed to move up and down at an upper portion of the binding device; A rotating body rotated by the rotating motor; And a pair of clamps provided on the rotating body.

Further, in a state where the clamps are fixed to each other at the upper end of the tightening portion so as to face each other, the rotation motor is driven to tighten the tightening portion.

In yet another embodiment, the binding device includes a pair of binding arms extending opposite each other, wherein in the binding position the fastening portion may be located between the binding arms.

After the tightening portion is tightened, the rotating motor is elevated so that the binding device can bind the binding member around the tightening portion in a state in which the receiving portion is supported by the binding arms.

The automatic binding apparatus may further include a plunger for discharging the food packaging material bound by the binding member from the binding position.

The binding apparatus is provided so as to be movable back and forth along the conveying direction of the conveyor so as to detach the binding member from the binding position after binding the binding member to the food packaging material.

The food packaging material to which the binding member is bound can be discharged in a direction perpendicular to the conveying direction of the conveyor by the plunger.

When the food packaging material is placed on the conveyor, the above-described automatic binding apparatus can automate the process from transferring the food packaging material to binding and releasing the binding members such as bands and ties and contributing to the improvement of productivity. In addition, since the worker only needs to place the food packaging material to be bound in the feeding position of the conveyor, the skill can be easily improved, the fatigue of the worker can be improved, and the productivity can be further improved.
