The present invention relates to an automatic band sealing machine for sealing vinyl bags. Especially, the automatic bag feeder is manufactured by unwinding and cutting the vinyl bag fabric wound around the roll by a predetermined length, and then sealing one end of the bag by heat-sealing it. To an automatic band sealer.

In general, confectionery, bread, or other powdered or granular items are packaged in plastic cardboard for storage, transportation, and sale. Although there is a method of wrapping, this method is not difficult in the case of an article that maintains a three-dimensional shape in a normal state, but it is difficult to surround the article with a flat vinyl paper as the powder or small particle articles have no three-dimensional retention. .

Therefore, in order to easily package such a three-dimensional non-maintaining article, the vinyl tube paper blow-molded into a tube shape in which both sides are integrally connected to each other is cut to a predetermined length, and the bottom edge is thermally bonded to the vinyl tube. By putting the items in the woven paper and heat-sealing the upper edges again, the method is simply put by simply pouring the non-stereo-type goods into the plastic tube that is connected to the bottom edge by heat-bonding. Will be able to.

By the way, in this way, when the continuous continuous tubing of the vinyl tube cut to a predetermined length and the lower side of the thermal bonding may be used by human hands using a thermal bonding mechanism, but not a lot of hassle, time and labor In addition, since the defect rate of the thermal joints is high, in general, where a large amount of vinyl tube paper is required, the machine is cut by a suitable length by a machine, and then mechanically thermally bonds the lower side of the cut vinyl tube paper. Automatic cutting machine and band sealing machine are used.

However, when using the automatic cutting machine and the band sealing machine there are a number of problems, that is, the automatic cutting machine and the vans sealing machine because it is composed of a separate process for receiving the vinyl tube cut out from the automatic cutting machine and this foundation The process of transferring the old vinyl tube paper to the sealing machine, the process of accurately inserting the vinyl tube paper cut by the sealing machine, and the process of collecting the finished product from the heat-sealed sealing from the sealing machine require a lot of people. In addition to the need for working personnel, especially when transporting the vinyl tube cut from the cutting machine to the sealing machine, it is inconvenient to work by carrying several stacked loads at once. Problems such as making it difficult to handle the vinyl tube that comes out There is.

On the other hand, it is proposed to combine the cutting machine and the sealing machine with each other so that the heat-bonding seal and the cutting are simultaneously made in one process in one device, that is, a vinyl tub wound around one end as shown in FIG. When the woven paper 100 is pulled by a predetermined length by the upper and lower drawer rollers 101 installed at the other end, the vinyl tube 103 protruding while the cutter 102 installed in front of the takeout rollers 101 is pulled out. A heat sealer having a heating means between a plurality of tension adjusting rollers 105A, 105B, and 105C, which allows the vinyl tube base 100 to be conveyed in a convenient manner to a conventional cutting machine 104 to cut the rear end of the sheet. (Not shown) There is a combination installed to change the position.

Such a device is used to variably adjust the position of the heat sealer according to the length of the vinyl tube paper 103 required, and then operate the device to rotate the upper and lower draw rollers 101 by a predetermined number of times, between the upper and lower draw rollers 101. To pull the vinyl tube paper 103 engaged to the front side by a length corresponding to the number of rotations of the take-out roller 101, and at the same time, the cutter 102 operates to break the stretched vinyl tube paper 103. At this time, the position of the heat-adhesive adjuster is lowered down to the bottom of the vinyl tube paper 103. The upper plastic cardboard is slightly melted with heat to press the heat adhesive bar, this heat-adhesive site is required vinyl tube paper ( Since it becomes a place corresponding to the predetermined length of 103, the heat-adhesive portion is positioned directly in front of the cutter 102 during the next vertical pull-out roller 101 operation. The thermal bond will cut the back immediately.

Therefore, this cutting machine equipped with a heat sealer has the convenience of the cumbersome process as described above and the need for a large number of people, as it can be heat-bonded to the lower end of the vinyl tube paper in one step and the cutting is carried out at the same time. However, the heat sealer installed in the device having the structure as described above does not have a function for cooling after fusion because it is intended to be temporarily fused with heat in the middle of the path through which the vinyl tubing paper proceeds, and the degree of fusion is low. And a strong thermal bonding is not made, and when the thickness of the vinyl tube paper is thick, there is a problem that the thermal bonding function is significantly reduced.

Therefore, if the vinyl tubing paper is thick or if a tight and durable heat seal is required, but somewhat inconvenient, it is using a separate band sealer as described above.

The present invention has been devised to solve the above problems, and by cutting and sealing the vinyl tube paper in a single process, one person can manage the entire process to reduce the number of people required and reduce the vinyl tube The aim is to provide an automatic band sealer that is capable of making sure the thermal bonds of the paper are firm and strong.

In order to achieve the above object, the present invention arranges the cutting machine for cutting and transferring the rolled vinyl tube base paper by a predetermined length, and the sealing machine for thermally bonding the vinyl tube paper transferred from the cutting machine is arranged at right angles. By installing a guide plate for guiding the cut vinyl tube to the connecting portion of the cutting machine and the sealing machine, the edge of the side to be bonded to the vinyl tube paper cut at the cutting machine by the guide plate is aligned in a straight line of the sealing machine The thermal bonding part and the cooling part are sequentially passed to be tightly and reliably thermally bonded.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
