Description

Tape height adjustable full-circumferential taping device

The present invention relates to a front circumferential taping device used to continuously tap the circumference of a styrofoam box (hereinafter referred to as a 'box') in which the upper part of the box body in an open state is sealed with a detachable cover, and more specifically, a tape By adjusting the height of the handle easily provided by the operation of the box can be used regardless of the height of the box cover, and by improving the configuration of the turning section for supplying the box taped from the first taping part to the second taping part taping operation It is to provide a tape height adjustable front circumference taping device that can improve the time.

Styrofoam boxes are mainly used to package agricultural products or aquatic products in a refrigerated or frozen state.

In the case of a styrofoam box, a box body having a storage space and a cover for sealing an open portion of the box body are usually formed, and in a state in which the box body is sealed with a cover, taping operations for bonding them with tape are performed. Relying on manual work.

On the other hand, various technologies for taping the box have been proposed, and as a representative example, an automatic taping device of the lower box of the Republic of Korea Patent Publication (B1) 10-1566420 (2015.11.05.) Has been proposed. Automatic taping allows the box packaging process to be performed quickly and smoothly, thereby increasing packaging efficiency and productivity, and simplifying the configuration for automatic taping under the box, increasing device durability and increasing device convenience. To be.

As another example, the automatic box taping apparatus of the Republic of Korea Utility Model Publication (Y1) 20-0336069 (2003.12.11.) Is proposed, the configuration of the box transfer conveyor for transporting the box containing the finished product; A side frame disposed in parallel on the box conveying conveyor and for advancing the box by engaging both sides of the box; A box width detecting unit installed on the side frame and configured to sense a width of the inserted box so that the side frame engages both sides of the box without damaging the box; Ball screws each installed perpendicularly to an arbitrary position of the box moving conveyor; A lifting frame which is engaged with both oppositely installed ball screws and is lifted and lowered by the ball screw; A taping unit installed to be disposed on the rear bottom surface of the elevating frame to automatically tap a box moving forward; A box cover folding unit installed in the elevating frame and automatically folding the box cover when the elevating frame is lowered; And a box height sensing unit installed on the elevating frame and controlling the height of the elevating frame such that the height of the elevating frame is sensed by sensing the height of the box that is inserted into the box surface to be taped.

However, in the case of the above-mentioned prior arts, most of the techniques for taping the symmetrical cover of the paper box do not provide the functionality to tap the circumference of the styrofoam box provided by the present invention, in particular agricultural products or aquatic products. As a configuration that cannot be used in the industry that handles the back in the frozen and refrigerated state, there is a demand in the industry for a taping device that can effectively tape the styrofoam box.

Therefore, the present inventor senses the width and height of the box supplied from the box input part and taps the two sides of the box from the first taping part while pressing the box cover, and is supplied through the pushing means provided in the turning part. By detecting the width and height of the box, the second taping unit can tap the remaining two sides of the box while pressing the box cover. It has been applied for a taping device for taping around the box to maximize the work efficiency by taping.

In the taping apparatus for taping the box circumference of the pre-applied box, it is very advantageous to tap the entire circumference of the box having various specifications, but when the taping position change occurs according to the cover thickness, the taping is impossible and the taping process is performed in the first taping part. Since the pushing plate which completely supplied the box to the second taping part is moved to the original position, the box can be supplied and thus workability is reduced.

Meanwhile, in the related art, a method of elevating a taping means by manual labor as a method for changing a taping position is used, and a means for solving the problem has been demanded in the industry.

KR 101566420 B1 2015.11.05. KR 200336069 Y1 2003.12.11.

Accordingly, the present inventors, as described above, in the taping apparatus for taping the box circumference of the present inventors, it is difficult to change the taping position when the product is different in the thickness of the cover, and to supply the box discharged from the first taping part to the second taping part. The present invention has been researched and developed to improve the problem that the box cannot be fed while the pushing plate is retracted by cylinder operation.

That is, in the present invention, the upper box transfer conveyor provided in the first taping part and the second taping part can be independently lifted so that the taping position can be easily modified according to the thickness of the cover. The box is supplied to the second taping unit and at the same time, the box supplied from the first taping unit can be moved to provide a tape height-adjustable front circumference taping device that can significantly reduce work time and improve workability during continuous operation. The present invention has been completed with the technical problem of the invention.
