Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of an apparatus for efficiently punching a large number of small holes on the side surface of a paper tube.

[0002]

2. Description of the Related Art A plastic film (sheet) is used for greenhouse cultivation of fruits and vegetables, but this film (sheet) is a product that is wrapped around a paper tube and is a product for the user. Is industrial waste that is difficult to dispose. In reality, these are collected and incinerated.

On the other hand, the soil that is the base of the planted tree is not ideal for the tree, and it may be necessary to add human hands. A particularly prominent example is often found in roadside trees. The soil in which the roadside trees are to be planted often has insufficient nutrients, water retention, air permeability, etc. for the plants to grow, and often cannot grow naturally. Therefore, inside the cylindrical body with many small holes on the side, zeolite, charcoal, bamboo charcoal, perlite, diatomaceous earth, wood chips, masa earth, etc. are filled, and this is located close to the tree, the lower end near the root of the tree And the upper end is buried so that it goes out of the ground,
It is known that soil properties are improved and tree growth is promoted. As the cylinder, a plastic pipe, a cloth bag, a paper tube, or the like can be used. Of these, the paper tube is biodegradable and does not need to be recovered once it is buried.The main body allows water to penetrate and raises the water in the ground to the ground by capillarity. It has been confirmed that it contributes to the growth promotion of cultivated rice, and is one of the preferable materials.

[0004]

Therefore, it is extremely preferable that a paper tube (core) that is incinerated as industrial waste can be reused as a cylinder to be embedded in a planted tree. In addition, it is often the case that the length and thickness of the core of commercially available agricultural films (sheets) are suitable for use as a cylinder for planting trees.

However, the operation of forming a large number of holes in the paper tube to form the cylindrical body is actually very troublesome. In the case of manual work using a hand drill, it is necessary to work on a very hard convex curved surface, and it is almost impossible to drill a large number of holes in a well-balanced manner in order to perform uniform water supply and drainage, unless you are fairly skilled. Is. Also, when using a drilling machine to mechanize, the work piece is a paper tube and unlike metal processing, it is difficult to chuck. There are problems such as that fixing work is sometimes impossible, and in reality, mechanization is difficult.

[0006]

Therefore, the present inventor has finally made the present invention as a result of earnest research in view of the above points, and is characterized in that a large number of small holes are spirally formed on the side surface of a paper tube. A device for opening the paper tube, a paper tube mounting table, a rotation mechanism section for holding the paper tube and giving a reciprocating rotary motion about the central axis to the paper tube, holding the paper tube and holding it for a long time. A slide mechanism portion for reciprocating linear movement in a direction, and a drill portion for making a small hole in a side surface of the paper tube, and gripping the paper tube in the rotation mechanism portion and the slide mechanism portion. The gripping of the paper tube in is controlled so as to be released when the other mechanical portion is operating, and the reciprocating rotational movement of the rotating mechanism portion and the reciprocating linear movement of the sliding mechanism portion are When the drill section is in operation, it is necessary to stop all of them. Lies in the fact that is.

That is, in the present invention, the "rotational movement" for reciprocating the paper tube and the "sliding movement" for linearly reciprocating the paper tube in the longitudinal direction are the "rotation mechanism section" and the "slide mechanism section", respectively. I am in charge of this, and I am trying to make these two movements progress alternately. Each of the mechanical parts has a gripping function for fixing the paper tube on the device without displacement and transmitting a rotational movement or a sliding movement to the paper tube.

When the paper tube is rotated at a certain step angle, the paper tube is gripped only by the rotation mechanism section, and the paper tube grip on the slide mechanism section side is released. On the contrary, when the paper tube is slid by a certain length, the paper tube grip on the rotating mechanism side is released.

Further, when the movement of both mechanical parts is stopped, the drilling part is operated to complete the perforation work, thereby performing a series of work continuously, thereby spirally forming a large number of small holes on the side surface of the paper tube. Is formed.

Here, the "paper tube" is a workpiece in the apparatus of the present invention and is a cylindrical pipe made of paper. It is suitable to use the "core" that remains as waste after using the agricultural plastic sheet, but it is not limited to this and naturally it is also possible to process other paper tubes. is there. The present invention does not limit the use of the paper tube processed by the device of the present invention.

The "paper tube fixing table" is a table provided in the apparatus of the present invention, and can be said to be a kind of rail configured so as not to prevent the paper tube from rotating or sliding. . The structure is not particularly limited, but a steel plate processed into a V-shaped cross section and installed so as to be opened upward is suitable for this purpose and is preferable.

As described above, the "rotation mechanism section" is a mechanism section that is in charge of gripping the paper tube and rotating the paper tube by an angle in the gripped state. The gripping and the rotation are performed in parallel. There is no such thing. For example, in the case of a structure in which a clamp is opened and closed by an air cylinder and the clamp is rotated by another air cylinder, the clamp is rotated only when the clamp is completely opened or closed,
It turns out that.

Similarly, the "slide mechanism section" also alternately performs two movements, and holds the paper tube and slides it by the distance in the held state.
Is the mechanical department in charge. It should be noted that each of the rotation mechanism section and the slide mechanism section has two movements, and its drive source may be air drive or motor drive. Further, the vertical movement of the drill blade in the drill section and the movements of both mechanism sections need to be controlled over the whole, but this control is also performed by a mechanical control method using an electric computer such as a microcomputer. There is no limitation as long as the control method is good.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail with reference to the drawings.

1 (a) and 1 (b) show an example of a paper tube punching device 1 according to the present invention (hereinafter referred to as the device 1 of the present invention). FIG. 1 (a) is a schematic front view, Figure (b) is a schematic side view. The drive source and other depictions are omitted.

As is clear from the drawing, the device 1 of the present invention includes a rail-shaped paper tube fixing base 3 installed on the machine base 2,
It comprises a drill unit 4 installed above this, a slide mechanism unit 5 for laterally feeding the paper tube, a rotation mechanism unit 6 for circumferential feeding, and the like.

As shown in FIG. 2, the drill unit 4 of this embodiment has a drill blade 41, a motor 42, and a shaft 4
Two types of air cylinders 44, 4 that move up and down along 3
It is composed of 5 and the like. Two types of air cylinders are provided in order to fast-forward the drill blade 41 to the vicinity of the paper tube and switch to cutting feed. However, such a mechanism does not limit the present invention. For example, if the drill blade 41 and the like are moved up and down by driving a motor, it is possible to shift gears with a single motor.
Two drill blades 41 are installed so that two holes can be obtained by one vertical movement.

Next, FIGS. 3A and 3B show the details of the slide mechanism portion 5 in the illustrated example. The slide mechanism portion 5 is a clamp for grasping and releasing the paper tube. It is composed of a portion 51 and a slide portion 52 that linearly reciprocates the clamp portion 51. The clamp portion 51 is reciprocated by the first clamp cylinder 53, and the slide portion 52 is reciprocated by the work shift cylinder 54. It should be noted that FIG. 7A is a front view of the entire slide mechanism portion 5, and FIG. 7B is a side view of the clamp portion 51 and the first clamp cylinder 53 portion.

The first clamp cylinder 53 and the work shift cylinder 54 do not operate simultaneously in order to maintain the accuracy of the lateral movement distance (after the first clamp cylinder 53 completely chucks the paper tube R). Otherwise, the work shift cylinder 54 does not operate). Further, when the work shift cylinder 54 returns to the original position, the clamp portion 51 is in the open state (the state where the paper tube chucking is released). Therefore, the paper tube surely moves laterally by a predetermined width in one unit of operation.

4 (a) and 4 (b) show the details of the rotating mechanism 6 in the illustrated example. The rotating mechanism 6 is a clamp part for gripping and releasing the paper tube. 61 and a support base 62 for reciprocally rotating the clamp portion 61 itself (45 ° in the apparatus of this example). The support base 62 partially fits into the guide rail 11 fixed to the apparatus main body side, and moves circularly while being guided by the guide rail 11. Further, the clamp portion 61 is the second clamp cylinder 6
3, the support base 62 is the work rotation cylinder 6
4 makes a predetermined reciprocating motion.
