Description

Detailed description of the invention

The present invention relates to a packing device for packing small articles mainly shipped by online shopping or the like.

With the expansion of online shopping, the ordering of small items (books, supplements, etc.) and the packing (or packaging) of them have increased dramatically, but since the items handled are small, transportation safety is improved. In order to maintain and keep the shipping fee low, a technology different from the packaging of ordinary goods is required.

Therefore, a sheet-like member having a two-layer structure with a material that can be heat-welded on the inside and a material that is not heat-welded on the outside is supplied from both sides (for example, from above and below), and the tips of the sheet-like members from both sides are welded in advance. A device has been put into practical use in which a small article is advanced toward it, and when the entire surface (upper surface and lower surface) of the article is wrapped, the rear end portion is welded and cut.

For example, the invention described in Patent Document 1 has an object of automating the work of putting a book or the like in a kraft envelope with an air cap and wrapping the kraft paper with an air cap. The book is sandwiched in the middle of the paper, pushed out from the rear with the pusher 2, and pulled from the front with the clamp device 4, and when the book passes a predetermined width from the position covered with kraft paper, both sides and the end portion are welded with the welding device 5. Discloses the technical concept of an automatic wrapping device (packing device) in which a book packaged by cutting the center of the end portion is discharged from the discharging device 31 and the remaining welded portion is used as the tip end portion of the next packaging.

An automatic wrapping device using such technology uses a pusher device to push out the kraft paper from the rear and at the same time pulls the tip of the kraft paper with an air cap from the front. Therefore, even a weak object to be packaged can be packaged without bending, and the efficiency and quality of automatic packaging can be improved.

JP-A-2004-26160

However, in the technique described in Patent Document 1, as shown in FIG. 1, of the pair of upper and lower reels 1 for supplying two volumes of air-capped kraft paper, the lower reel 1b is the inlet portion of the apparatus. Although it is housed in the lower part of the transport path, the reel 1a in the upper part is provided above the mechanism portion where the packaging operation is performed, so that there is a problem that the whole device, particularly the height, becomes large.

Similarly, since the entire device is integrated, it is difficult to carry it to the place of use as it is, and it requires a large heavy machine, or it needs to be disassembled at the time of shipment from the factory and reassembled at the place of use. There was also the problem that it was expensive, time consuming, and complicated.

In addition, since the entire device is integrally configured, even if the performance of a part of the device is improved, it is not easy to replace that part, and it is difficult to enjoy the latest technical performance. there were.

Further, the finished state (beauty) of the packaging is an extremely important factor for the contractor requesting the packaging from the impression of the customer who receives it, but in the technique described in Patent Document 1, the packaged object is packaged. In this state, both sides and the end portion are welded by the welding device 5, but since only the center of the end portion is cut, both sides are not processed and the finished product cannot be said to be beautiful. There was also.

If the unnecessary side parts are not cut, the charge is calculated based on the external dimensions, which is disadvantageous to the packing requester.

Further, Patent Document 1 has a technical idea that an object to be packaged is sandwiched between two sheets of kraft paper with an air cap whose tip is welded in advance, pushed out from the rear by the pusher 2, and pulled from the front by the clamping device 4. Although disclosed, since the clamping device 4 is single, it pulls (pulls) a long distance from the place where the packaged object is received (starting point) to the place where the packaging is finally completed and discharged (end point). It is necessary, and when the traction is completed, the long distance is returned to the starting point to correspond to the next packaged material, so the tact time (or cycle time) becomes longer and the overall processing capacity can be improved. There is a problem that it cannot be done.

Further, although not described in Patent Document 1, for a trader who operates such a device, a sheet-shaped member (kraft paper with an air cap) wound on a reel, which is a consumable item supplied by the device provider, is used. The cost burden is high, and usually, a sheet-like member wound on a reel is purchased and used. In that case, in order to reduce the cost burden, it is customary to purchase in bulk in large quantities, and there is also a problem that a large storage space is required.

The present invention is intended to solve such problems in the prior art, and is a packaging device capable of automatically and economically executing small items ordered by online shopping or the like with a simple configuration. The challenge is to provide.
