Abstract

PURPOSE:To facilitate the supply of bag making paper and to reduce noise at the time of operation by sealing the document supplied from a separate apparatus in the space between a pair of bag making papers cut into a proper size to form said papers into a bag. CONSTITUTION:Upper bag making paper (b) and lower bag making paper (a) are arranged by sending out them until the leading ends thereof strike against a positioning plate 6a intermittently moved up and down in matching relation to send-out timing. The document (c) gathered in a separate apparatus is passed under a guide plate 11 to be supplied on the lower bag making paper (a). Further, an upper send out roller 9 falls and the document is brought into contact with the bag making paper (a) under pressure to be sent out by a driven lower send-out roller 9a while the upper bag making paper (b) whose both ends coated with an adhesive or water by press rollers 10, 10' and the lower bag making paper (b) whose both ends crossing both ends of the paper (a) are coated with an adhesive or water by the rollers 10, 10' are closely bonded. By this method, both papers whose four edges are bonded are sent out in a bag form.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves enclosing documents supplied from another device between a pair of bag-making paper cut to an appropriate size until the bags are made. The present invention relates to an automatic bag making and sealing device that performs a series of operations.

[Prior art] Conventionally, conventional continuous foam paper is placed on top and bottom, and adhesive is applied while feeding intermittently, documents are fed onto the continuous foam paper on the lower side, and the continuous foam paper on the upper side is stacked, and the paper is placed on the left and right sides. A bag-making device that continuously cuts the perforated part with a slitter, while pulling and separating the horizontal perforated part with rollers at different speeds to form packaging bags, was developed by the applicant of this patent as shown in Patent Application No. 188600 of 1999. exists in

[Problems to be Solved by the Invention] It was difficult to place the continuous foam paper in the bag making device, and there were inconveniences such as noise being generated when separating the paper.

[Means for solving the problem] The present invention is an improvement to solve this problem. In other words, bag-making paper cut to an appropriate size is stacked on top and bottom, and the upper and lower bag-making papers are sent out one by one in the intersecting direction, and while being transported, adhesive or water is applied to both ends and overlapped. , collated documents or multiple folded documents supplied by linking with another device are fed between the upper and lower sheets and made into a packaging bag, and the bag making section cuts the The aim is to use processed bag-making paper to facilitate the supply of bag-making paper and to reduce noise during operation.

[Example] Next, an automatic bag making and sealing apparatus of the present invention will be explained based on the drawings.

Detachable shelves 1 and 1a are arranged above and below, and bag-making papers a and b are stacked on top of each other in advance.

The sorting rollers 2, 2', 2a, and 2a' are respectively on the shelf 1.
, 1a, and when the shelves 1, 1a are inserted, the middle plates 3, 3a are lifted up and pressed against the bag-making sheets a, b. Double feed detection sensors 4 and 4a detect double feed by comparing the amounts of light transmitted through the bag-making sheets a and b and the sample bag-making sheets a' and b', respectively. Feed rollers 5a, 5a', 5b, 5b', 5c, 5c', 5d,
5d', 5e, and 5e' are sorting rollers 2 and 2, respectively.
The bag-making sheets a and b taken out at ', 2a, 2a' are sequentially fed and hit against positioning plates 6, 6a that move up and down intermittently. Glue boxes 7 and 7a are removable, and adhesive or water is poured into them in advance, and application rollers 8 and 8a are driven to transfer and apply the adhesive onto bag-making sheets a and b. The upper delivery roller 9 is intermittently moved up and down by cam drive.

The pressing rollers 10, 10' are driven by a motor to press and send out the bag-forming paper.

[Function] In the present invention, the bag-making paper a is taken out one by one by the sorting rollers 2 and 2', and is fed to the position of the feed rollers 5a and 5a' in a direction that intersects with the direction of travel of the document, where double feeding is detected. After the sensor 4 compares the amount of light transmitted through the bag-making paper a and the sample bag-making paper a' and detects double feeding, the feed rollers 5a,
5a', adhesive or water is applied to both ends by application roller 8, and further sent out by feed rollers 5b and 5b' until the tip abuts against positioning plate 6. Similarly, shelf 1
The bag-making paper b stacked on a is separated by a roller 2a.
, 2a' take out one sheet at a time, and feed rollers 5c, 5c
The double feed detection sensor 4a compares the amount of light transmitted through the bag making paper b and the sample bag making paper b' and detects double feeding.
5d', adhesive or water is applied to both ends by the coating roller 8a, and the upper bag-forming paper is fed until the tip hits the positioning plate 6a, which moves up and down intermittently in accordance with the timing of feeding. The edges of the bag-making paper a on the lower side and b are aligned, and the documents collated from another device or the documents c that have been folded in multiples pass under the guide plate 11 and the edges of the bag-making paper a on the lower side line up. Supplied on top. Further, the upper delivery roller 9 descends and presses against the bag-making paper, and the lower delivery roller 9a that is driving sends it out, and the pressure rollers 10 and 10' apply adhesive or water to both ends. The upper bag-making paper b and the lower bag-making paper a coated with adhesive or water at both ends in the direction intersecting the paper are brought into close contact with each other, so that the four edges are adhesively bound and the bag is sent out. However, when applying water, use bag-making paper that has been previously coated with adhesive and dried.

[Effects] As described above, the present invention has a removable shelf that stacks bag-making papers, a sorting roller that takes out bag-making papers one by one, and a weight comparison between the taken-out bag-making paper and sample bag-making paper. A double feed detection sensor that detects feeding, a feed roller that sequentially feeds the bag making paper, an application roller that applies adhesive or water to both ends of the bag making paper being conveyed, and a positioning of the conveyed bag making paper. This is an automatic bag making/sealing device that is equipped with a positioning plate that aligns the edges, a feed roller that moves up and down to convey the bag-making paper with documents inserted and the edges aligned, and a pressing means that presses the paper. It helps streamline work, improves work efficiency, and saves labor. Furthermore, the device also has the feature that confidentiality can be maintained since the sealed letter creation process is performed continuously within the device.
