Description

[Detailed description of the invention] This invention can be installed on both sides or one side of various continuous business forms, including forms for direct mail and forms for filling in information output from a computer, and can be used when printing these business forms or This is related to a compression processing device for margins that has continuous through-holes that serve as a guide during transfer within the processing machine, and the margins that are cut in the foam processing machine and transported by an air conveying device, etc. are stored in a container in parallel with the work. The present invention relates to a margin compression processing device that can also perform compression work in the same container.

Conventional compression devices, as disclosed in, for example, Japanese Utility Model Application Publication No. 48-77975 and Japanese Patent Application Laid-open No. 50-90154, generally store the object to be compressed in a compression space closed by a compression member and a container. It is based on the technical idea that the compressor is stored in a full state and the compression operation is performed by contracting the closed compression space by lowering the compression member. In other words, it is based on the technical idea that the compression operation is performed by the compression surface of the compression member and the wall surface of the container. Therefore, the compression surface of the compression member is configured to be approximately the same size as the cross section of the container,
The object to be compressed is prevented from escaping from the aforementioned closed compression space. With conventional compression devices configured in this way, there is no problem when applied to compressed objects with low restoring force, such as garbage or ordinary paper waste, but it is difficult to compress objects with large restoring force, such as margins. In this case, when the compression member is removed above the container after the compression operation to open the compression space, the margin, which is the object to be compressed, immediately returns to its original state. This restoring force increases in proportion to the amount of margin stored. In order to prevent such restoration, it is necessary to apply an extremely large compressive force to the compressed object over a long period of time, which is much more than is normally required for the amount of stored margin, which is extremely inefficient. There is a drawback. In addition, in conventional compression devices, as mentioned above, the compression surface of the compression member and the cross section of the container are configured to have almost the same size, so objects to be compressed cannot be stored in parallel in the container during compression operation. However, it also has the disadvantage of being inefficient. To compensate for this shortcoming,
In order to make the most of the size of the container, it is necessary to store the object to be compressed until it is full and then perform the compression operation, but such an operation immediately leads to the first drawback mentioned above. As described above, the disadvantage of the inefficiency of conventional compression devices, which is exposed when compressing objects with a large restoring force, is that the compression operation is performed by the compression surface of the compression member and the wall surface of the container. This is attributable to the fact that it is based on the above-mentioned technical idea.

The present inventors believe that when manually compressing a narrow tape-like material with a large restoring force, such as a margin, it is better to fold it one by one than to compress a large amount of material with both hands. We focused on the fact that the restoration rate was low and the compression rate was high. In order to mechanically perform a compression operation similar to a folded state, the entire margin stored in the container is compressed at once using the compression surface of the compression member and the wall surface of the container, as in conventional compression devices. I came up with the idea that the best way to do this would be to sequentially compress each part of the data. In addition, when compressing a portion of the margin stored in the container in this way, the margin can be put into the same container in parallel with the compression operation, so the size of the container can be fully utilized.
We focused on its high work efficiency. The present invention has been made based on the above technical background.

The purpose of the present invention is to provide a margin compression processing device that can efficiently compress a margin with a large restoring force.The feature is that the compression surface of the compression ram is made smaller than the cross section of the rotating container at a predetermined position. By sequentially compressing the margin introduced into the container from a conveying pipe provided so as not to impede the compression operation of the compression ram, one part at a time, a large compression force can be generated with a small driving force to the compression ram. The margins are efficiently compressed by giving the container walls a certain amount of space, and the margins are allowed to escape in the lateral direction to some extent without directly using the container wall. It is structured in such a way that it can also be done.

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

First, the configuration of this embodiment will be described with reference to Figures 1 and 2. A circular cutout 2 is provided in the top plate of a base 1, and a circular rotary table 3, which has a diameter slightly smaller than that of the cutout 2 and corresponds to the diameter of the cutout 2, is supported rotatably on a shaft 4 so that its top surface is positioned above the top plate of the base 1. Within the base 1 below the rotary table 3, three rotary tables 3 are provided at equal intervals on the same circumference.
The support rollers 5 are provided to support the shafts 4 and to facilitate their rotation. A link sprocket 6 is provided on the shaft 4, which is provided inside the base 1, and is fixed to the rotary table 3 via a bolt 7. The link sprocket 6 and
A motor 8 equipped with a timer fixed on a base 1
The drive sprocket 9 at the lower end of the chain 1
The container 11 has a peripheral plate that is divided into two parts by a hinge 12. The lower end of one of the divided peripheral plates is welded to the upper surface of the turntable 3, which also serves as the bottom plate, so that the container 11 can move in conjunction with the turntable 3.
A notch 13 is provided at the other lower end to facilitate opening and closing. The upper bent ends of two supports 14 of any length fixed to the top plate of the base 1 are provided with mounting parts 15 that are parallel to the base 1 and positioned above the container 11.
A compression body 16 is attached vertically to the mounting portion 15. The compression body 16 has a pressing surface at the lower end of an air cylinder or the like 17 with an area smaller than the cross-sectional area of the container 11, is located above the approximate center of a line segment connecting the center of the container 11 and an arbitrary point on the peripheral side plate, and is equipped with a compression ram 18 which moves up and down relative to a rotational movement point within the container 11 as the container 11 rotates.

Note that 19 is a caster that allows the base 1 to be moved freely, and 20 is a plastic bag that is mounted inside the container 11. Reference numeral 21 denotes a conveying pipe connected to an air conveying device, which is fixed with a fixing bolt 22 to the tip of the mounting member 15 on which the compressor 16 is vertically installed, and which is connected to the upper part of the container 11 so as not to obstruct the vertical movement of the compressor ram 18. The margin is transported and dropped into the container 11 with the open end facing the container.

Next, the operation of this embodiment will be explained based on FIGS. 2 and 3. Margins (not shown) that are cut in one or more separate form processing machines and are appropriately air conveyed by an air conveyance device.
is dropped from the transport pipe 21 into the container 11 equipped with the plastic bag 20. When a predetermined amount of margin has accumulated in the container 11, the air cylinder or the like 17 of the compression body 16 is operated to reciprocate the compression ram 18 up and down. The compression ram 18 of this compression body 16 has a pressing surface with an area smaller than the cross-sectional area of the container 11, so that it constantly compresses the hypothetical surface A shown in FIG. 3, and compresses a part of the margin inside the container 11. It turns out. Further, the support roller 5 located below the compression ram 18 supports the pressing force. Next, when the compression of hypothetical surface A is finished, if the motor 8 equipped with a timer is operated for a certain period of time,
The drive sprocket 9 rotates the interlocking sprocket 6 via the chain 10, and the rotary table 3 is supported by the three support rollers 5 and smoothly rotates by a predetermined angle (see solid line arrows in Figures 2 and 3). )
Then, the hypothetical plane 1a of the margin advances to the hypothetical plane A. Therefore, the compression ram 18 is moved back and forth once to compress the hypothetical surface 1a that has arrived at the hypothetical surface A in the same manner as described above. In this way, the rotary table 3 is rotated in a fixed direction at predetermined angles, and in conjunction with this, the container 11 is sequentially rotated, and each time the compression ram 18 is applied to the hypothetical surface A to 1a to 2a, which is a part of the margin. ~ 3a, and is always compressed circumferentially at the position of the hypothetical plane A. At the initial loading position, the margin that is raised in a mountain shape is also affected by the sequential rotation of the container 11 and the compressed body 1.
Due to the sequential compression at step 6, it spreads laterally to some extent and gradually becomes flat. And depending on the rotation angle mentioned above,
When the rotary table 3 rotates the container 11 several times,
The entire margin will be uniformly compressed.
The margin is appropriately dropped into the container 11 in parallel with this compression operation without interfering with it. Repeat the above operation until the inside of the container 11 is filled with the margin to be compressed, then open one side of the circumferential side plate divided around the hinge 12 of the container 11 (see the chain arrow in FIG. 3), and insert the plastic bag 20 into This is to take out the stored compressed margin.

As is clear from the above explanation, the following effects can be achieved according to the present invention. First, it has a simple structure and is easy to manufacture. Second, since the container placed on the rotary table rotates in a fixed direction at a predetermined position, it suffices to occupy a small installation area. Third, the pressing area of the compression ram of the compression body is made smaller than the cross-sectional area of the container, and the compression operation does not use a closed compression space that directly uses the wall surface of the container, so the compression ram with a small pressing area has a small drive force. By applying force, a large compression force is obtained, and the margin spreads horizontally to some extent, making uniform compression possible.Furthermore, by making it possible to add the margin to the container in parallel with the compression operation. , it is possible to perform margin compression processing work extremely efficiently. Fourthly, paper powder, dust, etc., which are generated when compressing the entire upper surface of the margin stored in the container at once, do not stand up.

In addition, in the above-mentioned embodiment, the drive source of the compression ram in the compression body was an air cylinder, but this invention may be configured to move up and down by rotating the screw driven by a motor. It is not limited in any way.
