Abstract

PURPOSE:To automate a task by placing a gathered part of a bag at the center of a rotating plate by rotation of the rotating plate while an upper rim of a bag with a product such as vegetable put in is gathered up and held by a bag holding means and by simultaneously taping the gathered part with an adhesive tape. CONSTITUTION:After an object is put into a bag with an opening of the bag made of polyethylene or the like largely opened by a bag opening supporting means, a cam plate 35 is rotated by a motor 38 via a chain 39, whereby an upper part of the bag is gathered and held by a Y-shaped fixed claw 30 and a movable claw 31 due to retreat of a slide table 33. Then a control lever 52 is rotated clockwise by a motor 56 via a chain 55 and a lower plate 47 is moved to the right, whereby the gathered part of the bag is put into a long groove of a rotating plate 4 and at the same time an adhesive face of a nip tape of a tape pressing part of an adhesive tape 6 is attached to the bag. If the rotating plate 4 is rotated by the motor in this state, the gathered part of the bag is rotated, and the adhesive tape 6 is wound around the gathered part to be taped.

Description

Detailed Description of the Invention

[0001]

[Field of Industrial Application] The present invention relates to vegetables, fruits, root vegetables,
The present invention relates to a bag taping device in which articles such as processed foods and industrial products are stored in a plastic bag or a plastic bag, and then the upper opening of the bag is squeezed to be bound with an adhesive tape.

[0002]

2. Description of the Related Art Conventionally, it has been said that it is difficult to automate taping with an adhesive tape after bagging of this kind, which is done by hand. Therefore, there is a problem in that the taping work is labor-intensive, the bagging work is inefficient, and the cost is high.

[0003]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a bag taping device which solves these problems of the prior art and makes it possible to automate the taping operation quickly and inexpensively. Especially.

[0004]

Means for Solving the Problems The gist of the present invention which has solved the above problems is as follows: 1) A bag gripping means for gripping the upper edge of a bag accommodating an article is squeezed to extend from the peripheral edge to the center of rotation. A rotating plate with a long groove opened is rotatably provided, and an inserting means for inserting the upper part of the bag held by the bag holding means into the long groove of the rotating plate is provided, and the roll-shaped adhesive tape is rotated at a position away from the center of the rotating plate. A cutting means which is freely attached, and which is provided with a tape pressing portion for supporting the tip adhesive surface of the adhesive tape in the groove direction at the center of the rotary plate, and further cutting the adhesive tape portion between the tape pressing portion and the bag. 2) A bag taping device characterized in that the bag holding means is arranged at a fixed position, and the inserting means moves the rotary plate forward and backward toward the upper part of the bag to move the rotary plate by the mechanism to move the rotary plate into the long groove. Insert the upper part 1) Taping device for the bag 3) A pair of fixed claws having open ends and a pair of movable claws that are opened and closed are arranged so as to be vertically stacked, and a bag holding means is provided with a drive means that opens and closes the movable claws 1) or 2 4) The bag taping device according to any one of 1) to 3) in which the vicinity of the peripheral edge of the long groove opened in the rotary plate is fan-shaped.

Here, as the inserting means, there are means for moving the rotary plate to insert the upper part of the bag into the long groove and means for moving the upper part of the bag to insert into the long groove of the rotary plate, both of which include the present invention. Is.

[0006]

In the present invention, when articles such as vegetables and fruits are put into the bag, the bag gripping means operates to grip the upper edge of the bag by squeezing it. Next, the rotary plate moves in the bag direction, the long groove of the rotary plate inserts the narrowed portion of the upper edge portion of the bag, and the narrowed portion of the upper edge portion of the bag is placed at the center of the rotary plate. At this time, the tip of the adhesive tape adheres to the bag by coming into contact with the adhesive surface of the tip of the adhesive tape in the tape pressing portion.

Thereafter, when the rotary plate is rotated, the roll-shaped adhesive tape mounted on the rotary plate is swung around the squeezed upper edge of the bag inserted in the center, and the adhesive tape is taped accordingly. And adhere to the surface of the squeezed upper edge. By rotating the rotary plate once or a plurality of times, the adhesive tape is wrapped around the narrowed upper portion of the bag to close the opening of the bag and taping.

After taping, the rotary plate and the bag are slightly separated, and the cutting device on the rotary plate operates to cut the tape portion between the tape wound around the upper part of the bag and the holding portion. afterwards,
The rotating plate and the bag are separated and the taping operation for the next bag is started.
