Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a product (hereinafter simply referred to as a stick-shaped product) in which foods such as sugar and coffee, or various medicines are packed in a long and narrow stick-shaped bag. This invention relates to an automatic stacking device that collects and stores a large number of books in a container.

[Conventional technology]

Instead of the traditional method of manually packing stick-shaped products one by one into a container, a large number of stick-shaped products are condensed into a uniform thickness using a focusing arm (claw). Later, an automatic collection device was devised that would push all the materials together into a container and store them.

[Problem that the invention attempts to solve]

However, in the automatic stacking device configured as described above, when a large number of focused stick products are pushed into a container after removing the focusing arm, each stick product spreads outward like an umbrella. The pushing plate cannot be pushed smoothly.

In addition, if you try to push the product with too much force, the outer surface of the stick-shaped product that has spread outward will come into strong pressure contact with the rim of the container, causing the product's packaging surface to wrinkle or tear, causing the filling to be damaged. It may come out again.

In some cases, the stick-shaped product was bent in the middle.

Therefore, the technical problem of the present invention is to accommodate a large number of bundled stick-like products in a container extremely smoothly without wrinkles or bending.

[Means for solving problems]

The measures taken in the present invention to solve the above technical problems are as follows.

In an apparatus for storing a large number of bundled stick-like products in a container, the pressing surface of a pushing plate for pushing the bundled stick-like products is formed with an inner surface slightly smaller than the entrance area of the container, and , Protrudingly providing a holding frame into which the root end of the bundled stick-like product can be fitted.

[Effect]

The means configured as described above operates as follows.

That is, when the tips of a large number of stick-shaped products focused by the focusing arm are slightly inserted into the entrance of the container by the pressure of the pushing plate, and then the focus by the focusing arm is released, the entire stick-shaped product looks like an umbrella. However, since the root end of the stick-shaped product is housed within a holding frame whose inside is made slightly smaller than the shape of the entrance of the container, outward spread is suppressed. It is smoothly pushed into the container by the pushing plate.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the automatic stacking device according to the present invention described above will be described in detail below with reference to the accompanying drawings.

In FIG. 1, P is a stick-shaped product that is stored in a container T as shown in FIG. 2 by the automatic stacking device according to the present invention, and FIG. 3 schematically shows the overall configuration of the automatic stacking device. The configuration diagram explained in is shown.

In FIG. 3, numerals 1, . . . are stacking pots attached at intervals to a conveying device 2 constituted by an endless chain, and each bot 1 has a top surface as shown in FIGS. 4 and 5. It has a substantially U-shaped cross section with open front and rear end surfaces, and two notch grooves 1a and 1a extending from both sides to the bottom surface.
is drilled.

Each potted product constructed as described above is intermittently transported in the direction of the arrow in FIG. The system is such that products P... are supplied side by side. In FIG. 3, the reference numeral A indicates an accumulation section provided in the middle of the conveyance path, and this accumulation section A has upper and lower focusing arms 4, 4 provided two each on the upper and lower sides of the pot 1. 5.5, and a push-in plate 6 installed at one end of the pot 1, and at the other end of the pot 1, a container T held by left and right cylinders 73, 78 has an inlet Ta. They are set facing each other.

As shown in FIGS. 4 and 5, each of the upper and lower focusing arms 4.
4, 5, and 5 are attached to elevating plates 4a, 5a which are moved up and down by cylinders 4S, 5S, respectively, and when the bot 1 is transported to a fixed position, the upper focusing arm 4.4
descends and presses the upper part of the stick-shaped products P stored from the upper opening side of the pot 1, while the lower focusing arm 5.5 rises and pushes the stick-shaped products P from the notch grooves 1a, la. By pressing the bottom surface of the stick-shaped product P, these upper and lower focusing arms 4.4 and 5.5
As shown in FIG. 5, the whole of the container T has a circular shape, and its thickness is converged to a diameter slightly smaller than the area of the entrance Ta of the container T.

If the container T is square, the upper and lower focusing arms 4.
It goes without saying that the holding frame of the push-in plate 6, which will be described later, is similarly formed into a rectangular shape.

Further, 6S is a cylinder that moves the pushing plate 6 forward and backward, and on the front end suppressing surface of the pushing plate 6, there is an annular cylinder whose inner side (inner diameter) is slightly smaller than the area (diameter) of the entrance Ta of the container T. A holding frame 6a is formed, and the base end portions of the bundled stick-shaped products P are fitted and held in the holding frame 6a as shown in FIGS. 6 to 8.

When the bot 1 is transported to a fixed position, the pushing plate 6 configured in this way is operated toward one end of the pot 1 by the cylinder 68, and is operated by the upper and lower focusing arms 4.5 as shown in FIG. Focused stick-shaped product P...
・Insert the root end into the holding frame 6a, and push the tip side of the pressed and bundled product P a little into the entrance Ta of the container T on the opposite side. Further, when the above-mentioned pushing is performed, the upper and lower focusing arms 4.5 are opened up and down by the cylinders 4S and 5S to release the focusing, and then the pushing of the pushing plate 6 is continued as shown in FIG. The entire stick-shaped product P... is pushed into the container T in the state shown in FIG.

When the upper and lower focusing arms 4 and 5 move up and down to release the focusing (suppression), the entire stick-shaped product P... tries to spread outward, but the holding frame 6a of the pushing plate 6 To prevent this, the holding frame 6a can hold the stick-shaped product P...
Since the entire area (diameter) of the container T is kept smaller than the inlet area (diameter) of the container T, the stick-shaped product P can be pushed smoothly with little resistance by the pushing plate 6. Further, the container T into which the stain-like product P has been pushed is released from its holding according to the operation of the cylinders 75 and 7S, and is dropped into a packet or conveyor as it is, and a new container T is set again. This completes one collection operation.

The above-mentioned series of accumulation operations are repeated every time the pot 1 is sent to a fixed position, that is, the accumulation section A, thereby continuously providing containers T containing stick-shaped products P... I can do it.

〔effect〕

Since the automatic stacking device according to the present invention is as described above, it is possible to automatically store a large number of stick-shaped products in a container, but in the present invention, in particular, stick-shaped products are pushed into a container. A holding frame is provided on the push-in plate to prevent the stick-shaped product from spreading outward when the focusing arm opens up and down to unfocus, and to keep the overall thickness smaller than the entrance area of the container. Therefore, the pressing by the pressing plate is performed extremely smoothly, so there is no possibility of wrinkles on the sides of the stick-shaped product or the possibility of tearing the product and letting the filling come out, and there is no need to bend the product halfway. Since there is no plastic, it is useful for protecting products, and is suitable for use in collecting stick-shaped products filled with sugar, coffee, etc.
