Description

Compact Packing machine for pleat bundle

The present invention relates to a small packaging machine for fan-shape bundling, and more particularly, to make a compact configuration by reducing the overall volume of the small-sized packaging machine for fan-shape bundling, which is packaged by tying the entrance of the packaging bag with a bundling string or by taping with tape to bundle it At the same time, it relates to a small packaging machine for fan-shaped binding that is convenient for use.

In general, in order to package, store, or distribute various foods such as bread, fruits and vegetables, these various foods are put in a packaging bag and then, in order to seal the inside of the bag, directly tie the upper part of the opening part of the bag to seal the inside of the bag, or Alternatively, a method of sealing the inside of the bag by winding a tie (bundling string) on the outer surface of the bag containing food and then twisting both ends of the tie to bind it so as not to be untied has been used.

Among these packaging methods, the former packaging method is not only very difficult but also cumbersome to directly tie the upper part of the opening part of the bag. Moreover, there is a risk that the contents will be damaged when there are many contents, and the latter packaging method uses a separate tie. Therefore, it is possible to seal the inside of the bag without damaging the contents, but it takes time to pack because it is necessary to manually wind the tie on the outer surface of the bag containing the food and then twist both ends of the tie to bind it so that it does not come loose. It took a lot of work and the work efficiency was very low.

As a result, a fan-shaped bundling packaging machine has been developed and implemented for convenient and quick packaging. A look at the patent literature on the fan-shaped bundling packaging machine that has been developed and used so far is as follows.

Patent Application No. 10-2009-0009117 (2009.02.05) discloses that the upper outer surface of a packaging bag containing various foods such as bread or fruits and vegetables is automatically wound and twisted using a tie (string for binding) to close the inside of the bag. It relates to a tie binding machine that allows convenient and rapid packaging by sealing, the tie supply roll having a motor inside and formed behind the binding machine body covered with a cover body, the tie supply roll being wound in the form of a tie roll; A rotating body installed inside the cover body of the binder body and provided behind a horizontal substrate having an envelope insertion groove formed in the front and coupled to a rotating shaft rotating in a clockwise direction by a motor, and an envelope insertion groove side of the horizontal substrate A rotating body driving mechanism that is installed in the hood and rotates the rotating body by driving the motor by applying power to the motor by touching the terminal of the limit switch for motor driving while being pushed while inserting the upper side of the envelope, and the rotating body driving mechanism A tie feed mechanism for supplying the tie wound on the tie feed roll to the front bag insertion groove while driven according to the rotation of the rotating body, and the tip of the tie supplied to the front bag insertion groove by the tie feed mechanism touches the inside A tie guiding mechanism for guiding while being curved with a tie-inducing mechanism, a tie-cutter mechanism for cutting the tie guided and supplied to the correct position by the tie-supplying mechanism and the tie-inducing mechanism, and both ends of the tie cut by the tie-cutting mechanism A tie bending mechanism for bending the tie so that the tie wraps around the outer surface of the bag and gathers inward by pressing This is done by providing Patent Application No. 10-2009-0134149 (2009.12.30) is a horizontal direction that adopts a method of suturing the upper opening by twisting and sealing the upper opening with a bundle through the wrinkle forming unit while vertically transporting the wrapping paper in the horizontal direction. It relates to a corrugated wrapping paper twisting device for vertical twisting, comprising: a horizontal transporting means having a conveyor belt installed in a horizontal direction to erect and transporting food wrappers filled with contents; a guide unit for collecting the openings of the food wrapping paper through the guide rod and transferring them to the wrinkle forming unit (K); The wrinkle forming unit (K) for wrapping the opening of the food wrapping paper moved to the open twisted part of the wrinkle forming unit (K) through the guide part and the horizontal transfer means is twisted with a bundle string; constituted by combining, but the food wrapping paper is upright The packaging is completed by twisting the opening of the wrapping paper in the upper direction with the wrinkle forming unit (K) on the upper part of the body. Patent Application No. 10-2011-0043989 (2011.05.11) discloses that the rail bar and the folding plate of the folding unit interlock and the opening of the packaging pack is folded at regular intervals, and the taping unit rises to close the opening of the folded packaging pack between operation and between fixed About the fan-shaped binder that automatically cuts the end of the tape through the cutter for the next operation when the operation is approached and the packaging operation of wrapping the tape to the outside of the packaging pack through the rotating roll inside is completed. a folding unit in which a rail bar fitted with a folding plate that is folded multiple times is formed vertically; A pressing roll that is formed at a vertical position toward the lower end of the folding unit and is connected by a hinge and is mounted between an operation and a fixed interval so that the operation can be interlocked toward the fixed interval, and is mounted toward the operation at the upper end of the fixed interval, the pressing roll A taping unit comprising a rotating roll mounted between operations corresponding to the central axis and an eccentric axis penetrating through the center and an eccentric axis penetrating the eccentric position, and an interlocking means for interlocking the rotating roll; is folded into a folding unit, the taping unit rises to the top of the folding unit, and the rotating roll rotates between the pressing roll and the rotating roll through an eccentric central axis and an eccentric axis to seal the opening of the packaging pack using a tape. Utility Model Registration Application No. 20-1999-0021830 (October 11, 1999) relates to an automatic bag binding machine that can automatically close the opening of a bag with a simple structure, and a base having a cutout into which the opening of the bag is inserted.
