Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method of attaching a fan-shaped paper made of paraffin or the like to the opening of an enoki mushroom cultivation container in consideration of hygroscopicity, breathability, and the strength of the paper white body. It relates to an automatic paper rolling device that automatically wraps paper according to the growth of fruiting bodies.

As a conventional device of this type, Japanese Patent Application Laid-open No. 124426/1983 has been proposed. This involves dropping the sheets of paper one by one from the paper storage section onto the feeding path of the cultivation container under their own weight, feeding the cultivation container into the feeding path via a flexible wire, and pressing the sheets of paper that have fallen under their own weight into contact with each other. Bending the above paper to follow the shape of the opening of the cultivation container 1! Ru J: It was made by a sea urchin.

Such a device has the advantage of being able to bend the paper to follow the shape of the opening of the container by using the feeding of the cultivation container. In some cases, the paper may be shifted, tilted, or deformed, and when the cultivation container is pressed against the paper, the paper may not be in the desired state.
1- There is a problem in that it tends to cause problems in winding accuracy such as downward shift. This kind of problem is relatively rare when the paper is flat and stiff and new, but this paper is used repeatedly dozens of times, and as the number of uses increases, the paper becomes more flexible. The fact is that problems arise due to the fact that the paper rolls and deforms, making it difficult to implement this type of automatic paper winding device.

Another device of this type has been proposed in Japanese Patent Publication No. 55-42801. In this case, the paper at the top of the stack is held by suction, one end of the paper is fed straight to a guide position provided close to the mouth of the container, and an endless belt is passed around a pulley. As the material moves, it wraps around the mouth of the container. However, if the paper is new and flat and stiff, it is comparatively rare, but this paper is used repeatedly dozens of times, and as the number of times it is used becomes relatively large, the paper may warp. If the bottom edge of the paper fed along the guide is deformed or bent, it may shift downward or the paper may tilt, making it inconvenient to wrap it around the opening of the container. 1-Easy to use.

This invention was made in view of these circumstances,
Our purpose is to solve the problems mentioned above by providing an automatic paper wrapping device for enoki mushroom cultivation containers that can wrap well even paper that has been used many times, as well as new paper. The structure is characterized by a paper storage section and a small number of suction members (one of which is moved backwards to take out a sheet of paper from the paper storage section and hold it by suction on the suction member; In order to supply the paper to the mouth of the cultivation container while holding it by suction, there is a second actuating cam that reverses the suction member shown in -, and a paper presser that holds the paper approximately at the center of the paper that has been supplied to the mouth of the cultivation container 1B. Low 4 3rd step to move the paper presser back and forth so as to press and hold a part of the paper presser.
An operating cam, a fourth operating cam that operates a member, and a fourth operating cam for winding the second side of the paper, which wraps one side of the paper held against the opening of the cultivation container around the opening, and a fourth operating cam, which wraps the other side of the paper, around the opening. The wrapping is provided with a fifth actuating cam that operates the member, and each of the above cams is driven by a drive device as appropriate, and the paper sucked and held by the suction member is supplied to the mouth of the cultivation container at a predetermined location. By transporting the paper in its adsorbed state and holding it pressed against the opening, it is possible to stably wind the paper, and these operations are ensured by a cam mechanism.

Next, an embodiment based on the above characteristics will be described with reference to FIGS. 1 to 8.

A drive source A is attached to the main body of the automatic paper rolling device for the enoki mushroom cultivation container, and the rotation of this drive source A is transmitted to a cam shaft B, and each cam C, D, E, F, and G are connected to this cam shaft B. Mounting G
) and each cam C, D, E by the same transfer of the above cam shaft B.

-5- F and G are configured to operate. The first actuating cam C, which moves back and forth in the paper storage section formed in the automatic paper winding device of the enoki mushroom cultivation container, takes out a piece of paper from the paper storage section, and holds it by suction on the suction member will be explained.

As shown in FIGS. 1 and 2, reference numeral 1 denotes a paper storage section in which a large number of fan-shaped papers 2 are vertically stacked and stored upside down, and the paper storage section 1 is folded so as to be movable back and forth. And Figure 4 (A>(B)
An example of a first L-shaped link 1b in which one end of a connecting rod 1a is pivotally supported at the lower part of the paper storage section 1, and the other end of this connecting rod 1a is rotatably provided around a support shaft 1. is supported by
The other side of the link 1h is connected to the camshaft B via the roller 1C.
A spring 1d is provided on the link 1h so that the roller 1C always elastically engages with the first operating cam C. In addition, in the paper storage section 1, there is a push plate 4 which has the central part of the stacked papers 2 protruding into a mountain shape and can be pressed and held by the elastic force of the spring 3 in response to the opening of the paper bracket 2. is arranged, and the laminated paper 2 is held between this push plate 4 and a pair of stoppers 5 provided on both side walls of the paper distribution storage section 1. .

Reference numeral 6 denotes a pair of left and right arms that are arranged to face the paper 2 stored in the paper storage section 1, and a suction cup 7 is pivoted to the tip of each arm 6 by a support shaft 8 so as to be able to swing freely in the left and right directions. At the same time, the suction cup 7 is given an elastic force by a spring 9 so as to swing inward at all times, and is held by a stop bar (not shown) in a state inclined inward at approximately 45 degrees. Further, when the suction cup 7 is tilted inward at approximately 45 degrees, an actuation bottle 10 is provided on the base side of the suction cup 7, and the actuation bottle 10 is arranged so as to protrude from the suction cup 7 with respect to the paper 2. The tip 10a of the bottle 10 is bent outward.A positive pressure generating device (not shown) such as a vacuum pump is connected to the suction!87.

Therefore, when the first actuating force C rotates due to the rotation of the camshaft B, the roller 1C gradually moves to the concave arc portion C-
The 1-type link 1b descends towards J, and the force of the bullet 1d
The paper storage section 1 moves forward via the connecting rod 1a because it rotates around the support shaft 1. When the paper storage section 1 moves forward, the tip end 10a of the operating bin 10 first comes into contact with the outermost paper 2 among the multiple stacked sheets of paper 2, and as the paper storage section 1 moves forward, the operating bin 10 Since the tip 10a slides on the paper 2 and moves outward, the suction cup 7 integrated with the operating bottle 10 rotates outward, that is, toward the plane of the paper, against the elastic force of the spring 9, and the suction cup 7 moves toward the plane of the paper. It becomes almost horizontal and absorbs Gio 2.

After the rotation of the camshaft B, the roller 1G climbs toward the convex arc C'' due to the rotation of the first operating cam C, and the type 1 link 1b reverses around the spindle 1'' against the force of the bullet 1111d. Due to the rotation, the paper storage section 1 moves backward. When the paper storage section 1 moves back, one sheet of paper 2 remains attached to the suction cup 7, and the other sheets of paper 2 move backward as the paper storage section 1 moves. As the suction cup 7 retreats, the suction cup 7 returns to the inward oscillation state of approximately 45 degrees due to the elastic force of the spring 9, so that the paper 2 attracted to the suction cup 7 is shaped into an approximately U-shaped curved shape. . In this case, the paper storage section 1 is moved forward and backward by the first operating cam C, but the suction cup 7 and the arm 6
You may move forward or backward on the side. Further, although the suction cup 7 is oscillated at approximately 45 degrees, it only needs to be tilted inward at an appropriate angle and the angle may be changed as appropriate. Further, the paper storage section 1 is provided with a push plate 4 formed in a protruding mountain shape to facilitate suction, but the push plate 4 may be formed flat. Further, although the disc-shaped suction cup 7 is illustrated, its shape and structure may be changed as appropriate.

Next, the second actuating cam D reverses the suction member in order to supply the paper to the mouth of the cultivation container while holding the paper by suction, and a paper presser presses the paper that has been supplied to the mouth of the cultivation container approximately in the center. The third operating cam E for moving the paper presser back and forth so as to press and hold the paper presser against the opening will be explained.
