Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement in a means for transporting packaging paper in a packaging device.

<Prior art> Conventionally, this type of transfer means was disclosed in Japanese Patent Application Laid-Open No.
The one described in Publication No. 94393 is known. This transfer means includes a packing paper holding part for holding the packing paper, a tentacle arranged below the packing paper holding part to pull out the packing paper, and a tentacle provided on the lower side of the packing paper holding part. The tentacle includes a tearing plate, a guide rail provided in the movement path of the tentacle, and a pusher movably provided with respect to the guide rail. Then, while the tentacle pulls out the packing paper and moves it downward, the tearing plate forms the packing paper into a box shape and places it on the guide rail, and the pusher removes the box-shaped packing paper on the guide rail. It is designed to be moved by pushing.

<Problems to be solved by the invention> In this transfer means, the pusher pushes the box-shaped packing paper on the guide rail, so smooth transfer is possible with the packing paper assembled in a box-shape. However, it is difficult to transport items smoothly using sheet-shaped packaging paper. In particular, various types of packaging paper are used, including thick packaging paper such as cardboard packaging paper, as well as thin and flexible packaging paper, depending on the type of item to be packed and the type of packaging method. Therefore, it is desired to develop a transfer means that can handle these various types of packaging paper.

In addition, when the pusher pushes the box-shaped packing paper on the guide rail and transfers it, it is difficult to accurately position and transfer it to the destination, and when transferring it to the correct position, various guides and Requires control means.

Furthermore, when the pusher pushes and transfers the box-shaped packing paper on the guide rail, movement in the lateral direction is possible, but movement in the vertical direction is difficult.

Therefore, the object of the present invention is to provide a transfer means for a packaging device that can transfer any type of sheet-shaped packing paper and can also transfer it with accurate positioning to the destination in any direction. shall be.

<Means for Solving the Problems> The present invention solves the above problems by providing a packaging paper transfer means for a packaging device having the following configuration.

The packing paper transfer means for a packaging device of the present invention includes a packing paper holding section 10 for stacking and holding sheet-like packing paper, and a packing paper disposed below the packing paper holding section 10. The packaging paper transfer unit 12 is provided with a packaging paper extraction device 11 and a packaging paper transfer section 12 for placing and transporting the packaging paper extracted by the packaging paper extraction device 11.

The bottom of the packaging paper holder 10 has a portion open to the outside so that the packaging paper can be removed.

The above-mentioned packing paper extractor 11 has a tentacle 13 having a suction part 14 capable of adsorbing packing paper at the tip, and this tentacle 13 is arranged below the above-mentioned packing paper holding part 10. , can be raised and lowered, and in this raised position, the packaging paper facing the open bottom portion of the packaging paper holder 10 is sucked.

The above-mentioned packing paper transfer section 12 includes a mounting section 16 on which a sheet of packing paper is placed and transported to an appropriate location. This mounting section 16 is configured to reciprocate between a suitable position on the ascending and descending path of the tentacle 103 and a transfer destination. Furthermore, this mounting part 16 has an opening 15 that penetrates in the vertical direction so that the tentacle 13 can pass in the vertical direction.
When the tentacle 13, which has a sheet-shaped packing paper attached to its tip, descends through this opening, it receives and places only the sheet-shaped packing paper, and the tentacle 13 is transported with the sheet-shaped packing paper placed thereon. The packing paper is transferred by moving to the destination.

<Function> In the present invention, the placing portion 16 is attached to the tentacle 1.
By having an opening 15 that penetrates in the vertical direction so that the tentacles 13 can pass in the vertical direction, the tentacles 13 that have absorbed the sheet-shaped packaging paper held in the packaging paper holding section 10 descend through this opening. When doing so, only the sheet-shaped packaging paper is received and placed. The placing section 16 transfers the packaging paper by moving it in this placed state. In this way, since the package can be transferred to the next destination while it is received and placed, it can be transferred smoothly regardless of the thickness or hardness of the sheet-shaped packaging paper. Moreover, since the placing unit 16 receives the sheet-like packing paper and transfers the sheet-like packing paper together with the placing unit 16, the packing paper is easily transferred to the destination of the placing unit 16. This allows for reliable positioning. Even when particularly precise positioning is required, precise positioning can be achieved by simply temporarily fixing the packaging paper to the mounting section 16 using a suction device or a clamping device, for example, without using complicated control means. Furthermore, since the sheet-shaped packing paper is transferred together with the placing section 16, the packing paper can be placed at the desired position by simply moving the placing section 16 not only horizontally but also vertically. Can be transported.

<Embodiments> Hereinafter, preferred embodiments of the invention will be described in detail by way of example with reference to the drawings. However, unless otherwise specified, the dimensions, shapes, materials, and relative positions of the components described in this example are not intended to limit the scope of this invention. , is merely an illustrative example.

FIG. 1 shows an embodiment of the present invention. This is a plan view of the entire packaging device. Broadly speaking, the apparatus is composed of an article transfer section A, a packaging paper transfer section B, and a packaging section C. The following is a step-by-step explanation, but the main part of this invention is the packaging paper transfer section B.
is embodied in.

<<Packaged Object Transfer Section A>> It mainly consists of a first belt conveyor 1, a second belt conveyor 2 and a third belt conveyor 3 arranged near the end point of the first belt conveyor 1. That is, the second belt conveyor 2 and the third belt conveyor 3 are arranged in the extending direction from the end point of the first belt conveyor 1, which transfers objects to be packed from other places. The second belt conveyor and the third belt conveyor are configured to be slidable toward each other (in the X-X' direction).
Here, as an example, the following configuration is given. As shown in Fig. 2, rod-shaped bodies 5, 5 are inserted through both ends of two long strip plate-shaped bodies 4, 4, which are arranged parallel to each other so that their plate surfaces face each other. (If you look at it, it will look like a # character). The plate-shaped bodies 4, 4 move away from each other along both the rod-shaped bodies 5, 5 (the rod-shaped bodies 5, 5 move away from the plate-shaped bodies 4, 4).
Although it penetrates through the plate-like bodies 4, 4, it is configured to be slidable (not fixed to the plate-like bodies 4, 4). The method is to fix both plate-like bodies 4, 4 to external hydraulic actuators 6, 6 (as long as the plate-like bodies 4, 4 can be moved away from each other, this method is not limited to this method). Things to do are listed. One plate-like body 4 is provided with a second belt conveyor 2 on the surface facing the other plate-like body 4, and similarly, a third belt conveyor 3 is provided on the other plate-like body. Each conveyor belt is passed between the rod-like bodies 5, 5. The rod-shaped bodies 5, 5 have rolls 7, 7, 7, 7 of suitable diameters at respective positions on which the conveyor belts (of the second belt conveyor, the third belt conveyor) are hung. roll 7,
7, 7, 7 are rotatably fixed to the plate-shaped bodies 4, 4 around the rod-shaped bodies 5, 5, and can slide on the rod-shaped bodies 5, 5 as the plate-shaped bodies 4, 4 are opened and closed. can.
Although each conveyor belt (second belt conveyor, third belt conveyor) may be configured to receive rotational force from this roll, the following is listed for ease of implementation. The above roll 7,
In addition to 7, 7, 7, this time the (second
Rolls 8, 8 are provided on the side where the belt conveyor (of the belt conveyor, third belt conveyor) is provided so as to be in contact with the belt conveyor. These rolls 8, 8 obtain power from an electric motor or the like and transmit the power to the conveyor belts (of the second belt conveyor and the third belt conveyor). Both rolls 8,8 are
(2nd belt conveyor, 3rd belt conveyor)
If the configuration is such that the conveyor belt stops with the conveyed object T securely placed on it, adjusts the position of the transferred object T, and prepares for it to fall due to the opening and closing of the belt conveyor (second belt conveyor, third belt conveyor). more effective.

The explanation will be given by returning to FIG. 1 again. Pressing plates 9, 9, 9' are provided on the second belt conveyor and the third belt conveyor to adjust the state in which the transferred articles T are placed. Pressing plate 9,
9 slides on the second belt conveyor 2 and the third belt conveyor 3 and presses both sides of the transferred object T (with respect to the traveling method) to position it. Pressing plate 9'
, presses the transferred object T from the front (with respect to the traveling direction) and positions it in the same way. These positioning means ensure that the article T is dropped onto the packaging paper below the second belt conveyor 2 and the third belt conveyor 3. The pressing plates 9, 9, 9' are configured to slide back to their original positions once their positions are determined or when the transferred object T falls.

When implementing using the second belt conveyor 2 and third belt conveyor 3 as described above, the following problems may occur. When the transferred object T is a thin plate, the transferred object T is between the pressing plates 9, 9 and the second belt conveyor 2 or the third belt conveyor 3.
If it gets caught and is not placed in the correct position,
This is a situation where objects do not fall as planned due to the opening and closing of the belt conveyor. In consideration of this point, another embodiment is shown in FIG.

In this system, a roller conveyor 2' and a roller conveyor 3' are provided in place of the second belt conveyor 2 and the third belt conveyor 3. The roller conveyors 2', 3' have a plurality of rollers r rotatably fixed to the plate-like bodies 4, 4. The rollers r are arranged so that their axial directions are parallel, forming a horizontal roller group along the transport direction. It is sufficient that a suitable one of the plurality of rollers r rotates by itself to supply the conveying force (of course, this does not preclude all the rollers r from rotating by themselves). Each roller r is arranged at an appropriate distance d from each other. As shown in FIG. 7, the pressing plates 9, 9 have an appropriate number of hanging portions f passing through this gap d and extending in the hanging direction. This FIG. 7 shows the roller conveyor 2' viewed from the Y direction in FIG. 6.

Such hanging parts f, f are provided at appropriate positions of the pressing plates 9, 9 of both roller conveyors 2', 3' to prevent objects to be transported from being caught between the pressing plates 9 and the roller conveyors. There is.

2 extends from the chain conveyor 18, and the opening 15
It passes through and attracts and holds the packaging paper P. The sliding plate 16 returns to its original position (ie, under the holders 10, 10, 10, 10), leaving the packing paper P behind. Receiving plate 2
1 and 21 are packing paper P held by the suction unit 22
while supporting the lower surface of the second belt conveyor 2.
The moving object T falling from between the belt conveyor 3 and the third belt conveyor 3 is positioned front and rear. In detail,
As shown in FIG. 5, a predetermined number of moving objects T are piled up between the pair of receiving plates 21, 21 due to the descent of the suction part 22, the weight of the falling moving objects T, or both. . After that, as shown in FIG.
The pair of receiving plates 21, 21 on the chain conveyor 18 are moved and carried near a gluing device provided at an appropriate position on the chain conveyor 18 (not shown. If gluing is not required, this need not be performed). . After the packing paper P is glued at appropriate positions by the gluing device, the packing paper P passes through the folding devices 24 and 25 and the sides of the packing paper P are folded. 26 is a pressing device that presses the contents (transferred material T) from above so that they do not float up. In this way, the already packed item T′ is

It is effective to use appropriate sensors, numerical control devices, or both.

With the above configuration, the item to be packed (transferred item T) is packed in the packing paper P formed as a box, and depending on the item to be packed, the entire work process can be automated. . In addition to the above-mentioned packaging, it is possible to add a step of covering the object with the upper box as an applied example. The following items are added as incidental matters to the above-mentioned embodiment.

《Second packaging section D》 Deploy the second packaging section shown in Figs. 8 and 9 to the position D in Fig. 1. Here, the configuration around the packing paper P' and the extraction device 11 is omitted to avoid complicating the drawing.) This is an application of the configuration described in the description of the packaging paper transfer section B above. That is, holders 10', 10', 10', 10' that hold sheet-like objects P' (hereinafter used as a general concept of packing paper) placed from above, and this holder 1
0', 10', 10', and 10'; an extraction device 11' for taking out the sheet-like body P' from the extracting device 11'; and a sliding device 12' for further transporting the sheet-like body P' taken out by the extraction device 11'. The extraction device 11' includes:
By sliding the lower surface of the sheet-like body P' at the bottom of the holder 10', 10', 10', 10' by suction, the sheet-like body P' is removed from the holder 10', 10', 10', 10' It is possible to force the body P' to escape.

To explain each part in detail, the extraction device 11' has a long sliding part 13' and a suction part 14' provided at the tip of the sliding part 13'. The sheet-like material P' adsorbed to the suction portion 14' at the tip thereof is transferred by motion (this method may be one using fluid pressure, mechanical, or electromagnetic).

An example of an effective implementation of the suction section 14' is one in which a suction port of a vacuum pump or the like is provided in the suction section 14' to create a vacuum state between the sheet material P' and perform suction. .

The sliding device 12' is a plate-shaped body having an opening 15' on the plate surface (hereinafter referred to as the sliding plate 16'), and the sliding device 12' is a plate-shaped body having an opening 15' on the plate surface (hereinafter referred to as the sliding plate 16').

25', 25' slide to form side surface forming parts t, t,
Interrupt gluing is performed between t and t. It is appropriate to carry out this gluing using a hot melt type. After gluing, gluing portions 25', 25', 25',
25' returns to its original position. At the time when the folding is completed, or before or after that, the pressing part 2 is used to press the part of the packaging paper P′ that has been glued together.
Pressing members 26', 26' provided at 4', 24',
26', 26' slide horizontally to press the packing paper from the outside. These suction parts 23', 23', 2
3', 23', pressing part 24', 24', 24', 2
4', the gluing portions 25', 25', 25', 25' and the pressing members 26', 26', 26', 26' can be slid using an appropriate actuator or the like.

Packing is completed in the state shown in Fig. 13, and the suction part 2
3' and the pressing section 24' return to their original positions, and the packaged object (transferred object T) is urged forward by an appropriate pressing means and pushed out to the roller section G shown in FIG.

In cases where the process of packaging the upper box as described above is carried out, it is possible to avoid gluing the lower box for ease of removal. At this time, by removing the upper box, the sides of the lower box can be opened, making it easy to take out.

Holders 10, 10, 10, 1 of packaging paper transfer section B
0 is also the holder 10', 10', 1 of the second packaging section.
0' and 10' are both rod-like bodies that are erected and held with their longitudinal ends facing upward. Each holder is arranged as a set of four at appropriate intervals to form the vertices of a quadrangle. The rectangle having the holder as its apex is positioned so as to be somewhat smaller than the outer shape of the packaging paper. Then, in order to assemble the packaging paper P' into a box, the packaging paper P' is held in the holder by passing the notches made at appropriate positions in the packaging paper P' through the holder.

<Effects of the invention> As described above, the present invention provides a transport system for packaging equipment that can transport any type of sheet-like packaging paper and can transport it with accurate positioning in any direction. We were able to provide the means.
