Description

[Detailed explanation of the invention] [Field of industrial application] This invention is based on the idea of using fan-shaped paper made of paraffin paper or the like for the opening of the enoki mushroom cultivation container, taking into account moisture absorption, air permeability, and the strength of the paper itself. This invention relates to an automatic paper wrapping device for automatically wrapping paper according to the growth of fruiting bodies of enoki mushrooms.

[Conventional technology and issues]

A conventional device of this type has been proposed in Japanese Patent Application Laid-Open No. 124426/1983. 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. This allows the paper to bend to follow the shape of the mouth of the cultivation container.

This type of device has the advantage of being able to bend the paper to follow the shape of the container's mouth by using the feeding of the cultivation container, but on the other hand, the paper that falls under its own weight may deviate from the desired state. In addition, when the cultivation container is pressed against the paper, the paper may shift upward or downward from the desired state, which tends to cause problems in terms of wrapping accuracy. There is. This kind of problem is relatively rare if 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 actual situation is that problems such as slipping and deformation become apparent, making it difficult to implement this type of automatic cigarette winding device. Another device of this type has been proposed in Japanese Patent Publication No. 55-42801. In this case, the top layer of paper is held by suction, one end of the paper is fed in an upright position to a guide position provided close to the mouth of the container, and an endless belt stretched around a pulley moves to hold the paper in the container. I try to wrap it around the mouth of the person. However, although it is relatively rare that the paper is new and flat and stiff, this paper is used repeatedly dozens of times, and as the number of uses increases, the paper may warp or become deformed. If the lower end of the paper fed along the guide is deformed or bent, the paper may shift vertically or tilt, making it difficult to wrap the paper around the opening of the container.

This idea was devised in view of the above-mentioned circumstances, and its purpose is to make it possible to wrap not only new paper but also paper that has been used many times, as well as to make it possible to use a suction member with a simple structure. To provide a paper shaping mechanism in an automatic paper winding device for an enoki mushroom cultivation container that prevents damage.

[Means to solve the problem]

The present invention uses a paper shaping mechanism to take out a piece of paper from the storage section, shape it into a curved shape, and then feed the paper to the mouth of the cultivation container and wrap it around the mouth of the cultivation container to hold it. A pair of suction members are pivotally mounted at appropriate positions of the paper shaping mechanism so as to be rotatable laterally and are held in an inwardly inclined state, and the suction members are always urged inward. A bullet machine and a suction member are provided so as to always protrude toward the paper in the storage section, and by contacting the paper in the storage section before the suction member, the suction member is removed while resisting the force of the bullet. The paper storage device is configured to include an abutment piece that rotationally guides the paper storage section and an actuation mechanism that moves back and forth at least one of the paper storage section and the paper shaping mechanism.

[Effect]

With the above configuration, the suction member rotates as the storage section or the paper shaping mechanism moves back and forth to shape the paper into a curved shape, and the cultivation container is supplied with the curved paper to a predetermined location. By transporting and holding the paper in its shaped state up to the opening of the paper, it is possible to stably wrap the paper.

〔Example〕

Next, an embodiment based on the above characteristics will be described with reference to illustrative drawings.

First, one embodiment of an automatic paper rolling device for an enoki mushroom cultivation container will be described with reference to FIGS. 1A to 2B and FIG.

Reference numeral 1 denotes a paper storage section in which a large number of fan-shaped papers 2 are stacked vertically and stored upside down, and is provided so as to be movable forward and backward by an appropriate control mechanism (not shown). In addition, a push plate 4 is disposed in the paper storage section 1, which shapes the central portion of stacked papers 2 to protrude into a mountain shape, and which can be pressed and held by the elastic force of a spring 3 according to the amount of paper 2. The stacked papers 2 are held between the push plate 4 and a pair of stoppers 5 provided on both side walls of the paper storage section 1. Note that the paper 2 may be stored as a flat bundle of paper without protruding like a mountain. Also, a large number of them may be stacked horizontally.

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 provided at the tip of each arm 6 so as to be rotatable in the horizontal direction by a support shaft 8. In addition to being pivotally mounted, the suction cup 7 is always given an elastic force by the bullet 9 so as to swing inward, and is held by a stopper (not shown) in a state inclined inward at approximately 45 degrees. There is.
Further, an abutting piece 10 is provided on the base side of the suction cup 7 and is arranged so as to protrude from the suction cup 7 with respect to the paper 2 when the suction cup 7 is inclined inward at approximately 45 degrees. The tip 10a of the piece 10 is bent outward. Further, a negative pressure generating device (not shown) such as a vacuum pump is connected to the suction cup 7. Reference numeral 11 denotes an inversion shaft to which the base of the arm 6 to which the suction cup 7 is attached is fixed, and is pivoted on a pair of left and right receiving plates 12. The reversing shaft 11 is provided with an appropriate reversing mechanism 13 operated by a control mechanism (not shown). In this case, in the drawings, a rack 13b is arranged to mesh with a pinion 13a provided on the reversing shaft 11, and the arm 6 is reversed by the raising and lowering movement of the rack 13b. An actuator or the like may also be used.

14 is a cultivation container 16 supplied to a predetermined location 15
This is a curved paper presser that follows the shape of the opening 16a of the paper presser, and is arranged so as to be movable forward and backward by a control mechanism.
Although not shown, the negative pressure generating device of the suction cup 7 is turned off when the paper presser 14 moves forward, and turned on when it retreats. 17 is a retaining member capable of retaining the cultivation container 16 at a predetermined location 15.

A pair of rotating shafts 18 are installed vertically on both sides of a predetermined location 15 where the cultivation container 16 is held, and are rotated back and forth at an appropriate angle by a control mechanism, and an operating rod 19 is installed above each of the rotating shafts 18. At the same time, an elastic, curved lower winding arm 21 is attached to the support shaft 2 via a link 20 to one of the operating rods 19.
2, and a force directed toward the cultivation container 16 is constantly applied to the link 20 and the lower arm 21 by a spring 23, respectively. Further, an upper winding arm 24 is attached to the other operating rod 19 via a spring 25 on a support shaft 22.
a, and this upper winding arm 24 is formed with a concave groove 27 for housing a substantially C-shaped collar 26 made of an elastic material such as plastic. In the standby state, one collar 26 falls under its own weight and is stored in the groove 27, and when the upper winding arm 24 is operated, the shutter 28 works in conjunction with the upper winding arm 24 to prevent the collar 26 from falling under its own weight. In this way, the collar storage section 29 is arranged above the upper winding arm 24. Further, a paper receiving member 30 that contacts the lower end of the paper 2 and prevents the paper 2 from slipping downward from a predetermined position is pivotally attached to each operating rod 19 by a support shaft 31, and this paper receiving member A force directed toward the cultivation container 16 is always applied to the cultivation container 30 by a spring (not shown).

Therefore, when the paper storage unit 1 moves forward by an appropriate control mechanism, the tip 10a of the contact piece 10 first contacts the outermost paper 2 of the multiple sheets 2 stacked on top of each other before the suction cup 7. , and as the paper storage unit 1 moves forward, the tip 10a of the contact piece 10 slides against the paper 2 and moves outward, so the suction cup 7 integrated with the contact piece 10 is affected by the elastic force of the bullet 9. The suction cup 7 rotates outward, that is, toward the surface of the paper, and suctions the paper 2 so that the suction cup 7 is in a substantially horizontal state parallel to the surface of the paper.

After that, when the paper storage section 1 is moved back by an appropriate control mechanism, one sheet of paper 2 remains attached to the suction cup 7, and the other sheets of paper 2 move back as the paper storage section 1 moves.
At this time, as the paper storage section 1 retreats, the suction cup 7 returns to the inward rotation state of approximately 45 degrees due to the elastic force of the bullet 9, so that the paper 2 attracted to the suction cup 7 has an approximately U-shaped curved shape. The shape is maintained by contacting the contact piece 10. In this case, the suction cup 7 is held swinging at approximately 45 degrees, but the suction cup 7 may 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. Furthermore, the suction cup 7 and arm 6 side may be movable in advance and retreat, not the paper storage section 1 side. Furthermore, although the disc-shaped suction cup 7 is illustrated, its shape and structure may be changed as appropriate.

After taking out a sheet of paper 2 from the paper storage section 1 in this way, the arm 6 changes direction by approximately 180 degrees by the operation of the reversing mechanism 13, and the upside-down paper 2 is turned into a forward-facing position, either manually or by an appropriate method (not shown). The paper 2 is supplied to the opening 16a of the cultivation container 16 that has already been supplied to the predetermined location 15 by the supply mechanism, and the curved portion 2a of the paper 2 is arranged so as to correspond to the opening 16a. 14 moves forward by the control mechanism, the curved portion 2a of the paper 2 moves into the cultivation container 1.
The paper 2 is pressed against the circumferential surface of the opening 16a of the cultivation container 16 and is held in a substantially U-shape along the outer circumferential surface of the opening 16a of the cultivation container 16. Also, in the above explanation, the suction cup 7
Invert the arm 6 and open the opening 16a of the cultivation container 16.
The arm 6 of the suction cup 7 is arranged to be able to move forward and backward with respect to the paper storage section 1 which stores the paper 2 in a normal state, and the movement of the arm 6 back and forth moves the sheet of paper 2 into a curved shape. After shaping, the arm 6 may be further advanced without being reversed and may be supplied to the mouth portion 16a of the cultivation container 16, and the supply configuration may be changed as appropriate.

After that, the paper 2 is transferred and held up to the opening 16a of the cultivation container 16, and then the lower rotation shaft 18 is rotated by the control mechanism, and the operating rod 19, the link 20, and the lower arm 21 are moved toward the cultivation container 16. The tip of the curved lower winding arm 21 contacts the paper 2, and then the force of the spring 23 and the link 20
By this action, one side of the paper 2 is pressed against the opening 16a of the cultivation container 16, and the paper 2 is gradually wrapped while being pulled to smooth out the wrinkles.Then, the upper roll side rotating shaft 18 rotates, and the operating rod 19 and the upper roll are rolled. The arm 24 moves the other side of the paper 2 to the cultivation container 16 side, and the collar 26
Then, by the force of the spring 25, the other side of the paper 2 is wound along the opening 16a of the cultivation container 16 so as to smooth out the wrinkles, so that both ends of the paper 2 are overlapped vertically, and when the winding is completed, At the same time, the collar 26 separates from the groove 27 and automatically opens the mouth part 1.
6a and wrap the paper 2 around it to fix it. In this case, the paper receiving member 30 supports the lower end of the paper 2 in conjunction with the lower winding arm 21 and the upper winding arm 24.

After that, the upper winding arm 24 and the lower winding arm 2
1 returns, and the cultivation container 16 with the paper 2 wrapped around it is carried out manually or by an appropriate carrying out mechanism.
In that case, the lower arm 21 returns to its original position along the circumference of the opening 16a of the cultivation container 16 by the link action. The above is merely an example of a mechanism for fixing both ends of the paper 2 with the winding collar 26. In the above explanation, the collar 26 is formed so as to press directly against the paper 2 and wind it, but the upper winding arm 24 The collar 26 and the upper winding arm 24 may be pressed against the paper 2 and wound thereon at the same time. In addition, when wrapping paper, the collar may be fitted into the opening of the cultivation container by winding the paper using the lower winding arm and the upper winding arm, and then operating the separately arranged collar storage section. Alternatively, without using a collar, fasteners or the like may be provided in advance on both ends of the paper so that when the paper is wound around the mouth of the cultivation container, both ends of the paper are overlapped and fixed by the fasteners or the like.

Now, as shown in the above-mentioned example, in this invention, a sheet of paper 2 is taken out from the paper storage section 1 by the paper shaping mechanism A, and after being shaped into a curved shape, the paper 2 is supplied to the opening 16a of the cultivation container 16. It is designed to be held by being wrapped around the opening 16a of the cultivation container 16, and as shown in FIGS. A pair of suction members B held in an inwardly inclined state, a bullet 9 that always urges the suction members B toward the inside, and a bomb 9 that constantly biases the suction members B to the paper 2 in the paper storage section 1. The paper 2 in the paper storage section 1 is provided in a protruding manner, and comes into contact with the paper 2 in the paper storage section 1 before the suction member B, thereby swinging and guiding the suction member B outward while resisting the force of the bullet 9. The contact piece 10 is provided with an appropriate operating mechanism (not shown) such as a cam, cylinder, etc. that moves either or both of the paper storage section 1 and the paper shaping mechanism A back and forth. When the paper storage section 1 or the paper shaping mechanism A moves forward as shown in FIG. The suction member B rotates outward while resisting, and the suction cup 7 of the suction member B aligns with the paper surface and adsorbs the paper 2, and then, as shown in FIG.
Alternatively, when the paper shaping mechanism A retreats, the suction member B rotates inward due to the elastic force of the bullet 9, as shown in FIG. 4C and FIG. The contact piece 1 is curved and shaped into an almost U shape.
0 comes into contact with the paper 2 and its shape is maintained.

In this case, in the case where the contact piece 10 is not provided, the suction member B comes into contact with the paper 2 in an inclined state and is in a state where it rubs against the paper 2 while rubbing against the paper 2, which tends to damage the suction member B and the paper 2. However, the present invention does not cause such a problem.

Note that the contact piece 10 may be provided on the base side of the suction member B as shown in FIG. 3, or may be formed integrally with the suction cup 7 as shown in FIG. Further, when the suction member B is tilted inward at an appropriate angle and held by a stopper (not shown), the tip of the abutment piece 10 is positioned so as to guide the suction member B outward and rotationally. In that case, a bent portion 10a may be formed at the tip as shown in FIG. 5A, or the entire contact piece 10 may be inclined outward as shown in FIG. In FIG. 3B, 7a is an inner wall portion having a ventilation groove 7b.

[Effect of idea]

As mentioned above, this idea uses the paper shaping mechanism to take out a piece of paper from the storage section, shape it into a curved shape, and then feed the paper to the mouth of the cultivation container and wrap it around the mouth of the cultivation container to hold it. A pair of suction members are pivotally attached to a suitable position of the paper shaping mechanism so as to be rotatable laterally and are held in an inwardly inclined state, and the suction members are always directed inward. A biasing bullet is provided, and this suction member is provided so as to always protrude toward the paper in the storage section, and by contacting the paper in the storage section before the suction member, the bullet is attracted while resisting the force of the bullet. Since it is provided with an abutment piece that rotates and guides the member outward, and an actuation mechanism that moves back and forth at least one of the paper storage section and the paper shaping mechanism, at least one of the paper storage section and the paper shaping mechanism The paper can be shaped and held in a curved shape by the rotation of the suction member as the suction member moves back and forth, and by supplying the curved paper to the mouth of the cultivation container, it can be properly wrapped and fixed. This is done automatically, and by providing an abutment piece, the suction member can be suctioned in a state where it is aligned with the paper surface, and the suction member can be held with a simple structure, which has a great practical effect.
