Description

PET bottle packaging closing apparatus and packaging closing method using the same

The present invention relates to a PET bottle packaging closing apparatus and a packaging closing method using the same, and more particularly, by rotating the packaging paper while fixing the upper end of the packaging paper for packaging a PET bottle with a gripper, the packaging paper As the upper end of the bottle is compressed by rotation, the rotating part is configured to finish the packaging while the PET bottle is pressed, so that the packaging finish of the PET bottle is firmly established and the productivity per unit time is improved to strengthen the product competitiveness. And it relates to a packaging finishing method using the closing device.

In general, commercially available beverages are filled and distributed in one of cartons, glass bottles, aluminum cans, and PET bottles.

Among them, PET bottles are one of the most widely used packaging materials because they are light in weight and less likely to be damaged during distribution.

When these PET bottles are delivered to a large conglomerate equipped with fully automatic facilities, they are supplied in a bulk type stacked in multiple layers.

In contrast, individually packaged PET bottles are supplied to small and medium-sized enterprises that do not have fully automatic facilities.

This is because when bulk-type PET bottles are delivered from small and medium-sized enterprises, they have to be manually dismantled and then put into the sorter hopper, so it takes a long time to work, and the production cost is inevitably increased due to the increase in labor costs. There is this.

On the other hand, when bulk packaging PET bottles, a plurality of PET bottles are inserted in a rectangular shape inside a synthetic resin bag having a rectangular shape and an inlet formed at the tip, and then the inlet portion of the bag is sealed.

Looking at a conventional example, the PET bottle packaging device of Korean Patent No. 10-1911666 is, as shown in FIGS. 1A and 1B, a PET bottle manufactured by a blow molding machine and transported by a conveyor device in a rectangular shape, and an inlet is provided at the tip. As for packaging by putting the bag in the formed synthetic resin material, the conveyor device is provided to extend in the lateral direction.

A discharge guide provided to extend forwardly in front of the discharge end of the conveyor device and fitted with the envelope on the outside of the front end, a support provided to be positioned in front of the discharge guide, and a rear end to be rotated in the vertical direction on the support A pivoting table coupled to the front end of which is rotated in the vertical direction by the pivoting driving means, and an extension guide configured to extend in the front-rear direction and slidably coupled to the pivot in the front-rear direction to move forward and backward by the forward and backward driving means; A pusher provided at the rear of the discharging end of the conveyor device and pushing the PET bottle transported by the conveyor device to the front and inserting it into the bag fitted in the discharging guide, the rotation driving means, the forward and backward driving means and the pusher control means for controlling.

The discharge guide and the extension guide include a lower plate and a pair of side plates extending upward from both sides of the lower plate, and the extension guide is configured such that the width of the lower plate is wider than the width of the lower plate of the discharge guide, and the pivoting table is raised. The lower plate is provided on the pivot so as to be positioned lower than the lower plate of the discharge guide in the discharged state, and the outer surface of the side plate of the discharge guide is provided with a friction member for fixing the bag fitted to the discharge guide.

The envelope is fitted to the outer side of the discharge guide to be folded in the form of a bellows, and is provided on one side of the support and includes a folding means for folding the envelope in the form of a bellows.

The folding means includes a support block, a support bar that extends forward from the upper front surface of the support block and into which the envelope is fitted, and is slidably coupled to the support block in the front and rear directions to move forward and backward by the forward and backward driving means. And the suction hole to which the vacuum pump is connected is formed on the outer surface of the suction slide bar so that the bag is coupled to the outside of the support bar by sucking the front end of the bag fitted on the periphery of the support bar and pulling it backward; It is configured to extend from the front to the front, and the front end is configured to be in close contact with the inner bottom surface of the bag coupled to the outside of the support bar by the suction slide bar. The adsorption fixing member to be adsorbed and fixed to the front end portion, and is slidably coupled to the support bar in the front and rear directions, and is moved back and forth by a forward and backward driving means, and pushes the front end of the bag coupled to the outside of the support bar forward so that the bag is a bellows. It includes a push panel to be folded into a shape.

On the outer side of the side plate of the discharge guide, an adsorption block having an intake hole to which a vacuum pump is connected is slidably coupled in the front and rear directions on the outer surface of the front end, and a forward and backward driving means for moving the adsorption block back and forth is connected to the adsorption block. , When the adsorption block is advanced and the bag folded in the form of a bellows is coupled to the outside of the distal end of the discharge guide in a state in which the vacuum pump is operated, the adsorption block is retracted by the forward and backward driving means by pulling the bag backward , so that the bag is fitted around the discharge guide.

However, in the conventional case, in a small business, an operator performs the packaging operation one by one.

That is, by turning the spout of the wrapping paper containing the PET bottle and concentrating it on the spout to make it resilient, and then binding it with a binding member such as a string, the packaging is completed.

This has a problem in that productivity is significantly lowered due to the limitation of the number of pavements per unit time as workers individually perform paving work.

In order to improve this, the packaging was completed by heat-sealing the spout of the wrapping paper of the PET bottle with automatic packaging.

This improves the productivity per unit time, but simply cannot keep the space between the PET bottles loose as the space between them is loose due to thermal fusion to the spout, which causes problems such as poor lamination during lamination and separation of the plastic bottle during movement. do.
