Description

[Detailed Description of the Invention] This invention provides for the growth of fruiting bodies of enoki mushrooms by using a fan-shaped paper such as paraffin paper at the mouth of the enoki mushroom cultivation container, taking into consideration hygroscopicity, air permeability, and the strength of the paper itself. The present invention relates to an automatic paper winding device for automatically winding paper according to the requirements.

Normally, the paper wrapped around the mouth of the enoki mushroom cultivation container is formed into a conical shape, so that when the enoki mushrooms grow, they are kept neatly on the inside of the paper wrapped around the cultivation container. It is something that grows. However, if the paper loses its shape and the enoki mushrooms grow and extend upwards from the mouth of the cultivation container, the paper loses its shape and the enoki mushrooms bend outward from the mouth of the cultivation container. There is a fear that the enoki mushrooms will grow slowly and reduce the commercial value of enoki mushrooms.

In the conventional automatic paper winding device of this type,
124428, in which rubber connected to a pair of paper-wrapping arms is pressed against the opening of the cultivation container along with paper, or three roller groups are arranged on three sides, as in JP-A-55-138331. The paper can be wrapped around both sides of the paper by horizontally moving in conjunction with two groups of rollers, or a suitable number of curved swinging arms can be used to wrap the paper, as in Japanese Patent Application Laid-Open No. 138332/1983. A device that can be clipped and wrapped around the mouth has been proposed.

By the way, this type of paper is fan-shaped and is wrapped around the mouth of the cultivation container in a conical tube shape, so it is important to suppress the spread of the paper to an appropriate level, and if this control is insufficient, It is difficult to wrap it into a neat conical shape.

In other words, if the spreading of the paper is suppressed during rolling as shown in Figure 1A, the paper will be formed into a beautiful conical shape, but if the spreading of the paper is not suppressed during rolling as shown in Figure 1B. However, it may lose its shape and may not be wrapped around the mouth of the cultivation container in an appropriate manner.

Now, in all of the conventional devices mentioned above, only the wrapping of the paper around the mouth is considered, and since the paper is fan-shaped when rolled, both sides of the paper are wrapped around the mouth as shown in Figure 1B. As the paper rises further, the paper tends to spread out toward the end when it is rolled, making it difficult to automatically wind it into a conical tube shape in a stable state. Furthermore, it is generally considered appropriate to wrap enoki mushrooms in paper when they have grown more than 3 to 4 cm from the mouth of the cultivation container.
When the paper is rolled, the cap of the enoki mushroom is already located 3 to 4 cm above the mouth of the cultivation container, and as the caps come together, the cap protrudes laterally and the paper is pushed outward. There is a problem in automatic paper rolling work because the result is as shown in Fig. 1B.

The purpose of this invention is to provide an automatic paper rolling device for an enoki mushroom cultivation container that can solve this problem, and its characteristic configuration is to take out a piece of paper from a paper storage section and supply it to the opening of the cultivation container. After that, in an automatic paper wrapping device for an enoki mushroom cultivation container, the paper is wrapped around the mouth of a cultivation container housing enoki mushrooms in a substantially conical tube shape that widens toward the end using a pair of wrapping members. A paper presser is provided that presses approximately the center of the supplied paper against the mouth, and in conjunction with the operation of winding both sides of the paper by each winding member with reference to the approximately center portion of the paper fixed by the paper presser, At least a pair of curved paper pressing members are provided in an inclined shape following the shape of the side surface of the paper, which presses the side surface of the paper corresponding to the cap assembly position of the enoki mushroom into a substantially conical tube shape that widens toward the end.

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

First, an embodiment of an automatic paper winding device for an enoki mushroom cultivation container using the device of this invention will be described with reference to FIGS. 2 and 3.

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 laminated paper 2 is sandwiched and held between the press plate 4 and the presser member 5 provided in 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 disposed facing the paper 2 stored in the paper storage section 1, and a suction cup 7 is attached to the tip of each arm 6 so that it can swing freely in the left and right directions by a support shaft 8. In addition to being pivotally mounted, the suction cup 7 is always given an elastic force by a spring 9 so as to swing inward, and is held by a stopper (not shown) in a state inclined inward at approximately 45 degrees. . Further, an actuation pin 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
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. This reversing shaft 11 is provided with an appropriate reversing mechanism 13 operated by a control mechanism (not shown). In that 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 a support shaft 22 via a link 20 to one operating rod 19.
The link 2 is pivotally connected to the
0 and the lower winding arm 22 are each constantly applied with a force directed toward the cultivation container 16 by a spring 23. Further, an upper winding arm 24 is connected to the other operating rod 19 via a spring 25 on a support shaft 22a.
This upper winding arm 24 is made of an elastic material such as plastic and is pivoted so as to be able to swing freely.
A concave groove 27 is formed to accommodate a collar 26 of a shape, and when the upper winding arm 24 is in a standby state, one collar 26 falls under its own weight and is stored in the groove 27, and the upper winding arm 24 A collar storage section 29 is disposed above the upper winding arm 24 so that the shutter 28 works in conjunction with the upper winding arm 24 to prevent the collar 26 from falling under its own weight during operation. Further, a paper receiving member 30 that contacts the lower end of the paper 2 and prevents the paper 2 from sliding down from a predetermined position is pivotally attached to each operating rod 19 by a support shaft 30a, and this paper receiving member 30 is always given a force directed toward the cultivation container 16 by a spring 30b.

Therefore, when the paper storage unit 1 is moved forward by an appropriate control mechanism, the tip end 10a of the actuating pin 10 first moves the outermost paper 2 among the multiple stacked sheets 2.
Since the actuating pin 10 moves outward as the paper storage section 1 moves forward, the suction cup 7 integrated with the actuating pin 10 resists the elastic force of the spring 9 and moves outward, that is, toward the paper surface. By rotating, the suction cup 7 is brought into a substantially horizontal state parallel to the surface of the paper, and is attracted to the paper 2.

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 state of swinging inward at approximately 45 degrees due to the elastic force of the spring 9, so that the paper 2 attracted to the suction cup 7 becomes curved in an approximately U-shape. Shaped. In this case, the suction cup 7 is oscillated at approximately 45 degrees, but the suction cup 7 only needs to be tilted inward at an appropriate angle and the angle may be changed as appropriate. In addition, the paper storage section 1 has a push plate 4 formed into a protruding mountain shape.
Although the push plate 4 is provided to facilitate adsorption, a flat push plate 4 may also be used. Further, the suction cup 7 and the arm 6 side may be moved forward and backward instead of the paper storage section 1 side. Further, although the disc-shaped suction cup 7 is illustrated, its shape and structure may be changed as appropriate.

Next, after taking out a sheet of paper 2 from the paper storage unit 1, the arm 6 changes its direction by approximately 180 degrees by the operation of the reversing mechanism 13, and the paper 2, which is upside down, is now facing forward, either manually or by an appropriate feeding mechanism (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, and the curved portion 2a of the paper 2 is arranged so as to correspond to the opening 16a,
Next, when the paper presser 14 moves forward by the control mechanism, the curved portion 2a of the paper 2 presses against the opening 1 of the cultivation container 16.
The paper 2 is pressed against the circumferential surface of the cultivation container 6a and is held in a substantially U-shape along the outer circumferential surface of the opening 16a of the cultivation container 16. In addition, in the above explanation, the arm 6 of the suction cup 7
The paper 2 is inverted and supplied to the opening 16a of the cultivation container 16, but 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 in which the paper 2 is stored in the normal state. After the sheet of paper 2 is shaped into a curved shape by advancing and retreating, the arm 6 may be further advanced and supplied to the opening 16a of the cultivation container 16 without reversing, and the supply configuration may be changed as appropriate. You may.

Next, after the paper 2 is transferred and held up to the opening 16a of the cultivation container 16, the lower rotation shaft 18 is rotated by the control mechanism, and the operating rod 19, the link 20, and the lower roll arm 21 are moved toward the cultivation container 16. The side end of the curved lower winding arm 21 contacts the paper 2, and then, by the force of the spring 23 and the action of the link 20, one side of the paper 2 is pulled into the opening 16a of the cultivation container 16.
The upper winding side rotation shaft 18 rotates, and the operating rod 19 and the upper winding arm 24 move toward the cultivation container 16 to wrap the collar 26 at the end of the collar 26. contacts the other side of the paper 2, and then the force of the spring 25 causes the paper 2 to
The other side is wrapped around the opening 16a of the cultivation container 16 so as to smooth out the wrinkles, so that both ends of the paper 2 are stacked vertically, and at the same time as the wrapping ends, the collar 26 separates from the groove 27 and automatically Mouth part 16a
and wrap the paper 2 around it to fix it. In this case, a pair of paper receiving members 30 support 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. In addition, in the above example, roll both sides of paper 2 and roll color 2.
This is merely an example of a mechanism for fixing by 6.
In the above explanation, the collar 26 is formed so as to press directly onto the paper 2 and wrap it around the paper 2, but the upper winding arm 24
The collar 26 and the upper winding arm 2 may be formed so as to be directly pressed against the paper 2 and wound.
4 may be pressed against and wrapped around the paper 2 at the same time. In the case of winding the paper, the collar may be fitted into the mouth of the cultivation container by winding the paper with the upper winding arm and then operating the collar storage section provided individually. Also, by providing fasteners etc. on both ends of the paper in advance without using a collar,
When the paper is wound around the opening of the cultivation container, both ends of the paper may be overlapped and fixed using a fastener or the like.

Now, in this invention, for example, as in the above-mentioned embodiment, a piece of paper 2 is taken out from the paper storage section 1 and fed to the opening 16a of the cultivation container 16, and then the paper 2 is moved to the opening of the umbrella section by each arm 24, 21. The mouth portion 16a
In a container that is held by wrapping it around the mouth part 16a of a cultivation container 16 containing an enoki mushroom that has grown upward, it is held in a substantially conical tube shape that widens at the end, as shown in Fig. 7. A paper presser 14 is provided to press approximately the center of the paper 2 supplied to the section 16a against the mouth section 16a, and as shown in FIGS. In conjunction with the operation of the arms 24 and 21 that wrap both sides of the paper 2 based on the part, the side part of the paper 2 corresponding to the collecting position of the cap opening of the enoki mushroom is attached to the paper pressing member B. The curved paper pressing member A that presses the paper 2 into a substantially conical tube shape that widens at the end.
It is provided in an inclined shape following the shape of the side surface. In that case, the lower volume arm 21 and the paper pressing member A made of a curved band plate are formed integrally,
An arm 31 of a paper pressing member A made of a curved band plate is pivotally connected to the upper winding arm 24 by a support shaft 33 so as to rotate while receiving friction through an elastic force 32. A stopper pin 34 is erected on the operating rod 19 outside the arm 31 at a position near the arm 33 . Also, above the paper presser 14 that presses the paper 2 against the opening 16a of the cultivation container 16, a curved paper presser member B that presses the side surface of the paper 2 corresponding to the gathering position of the umbrella opening is connected. .
In this case, the paper pressing members A and B have a strength capable of pressing the aggregate of the cap openings, and are sloped in the longitudinal direction following the slope of the side surface during paper rolling as shown in FIG. 1A.

However, as shown in FIGS. 2 and 3, the paper presser 14
When the paper 2 is moved forward by the control mechanism, the curved portion 2a of the paper 2 is pressed and held in a substantially U-shape along the outer circumferential surface of the opening 16a of the cultivation container 16, and at the same time is continuously connected above the paper presser 14. The curved paper pressing member B also presses and holds the side surface of the paper 2 corresponding to the gathering position of the umbrella opening.

Thereafter, as shown in FIGS. 5A, B, and C, the curved lower winding arm 21 moves toward the cultivation container 16 and its tip comes into contact with the paper 2, and then due to the force of the spring 23 and the action of the link 20. As one side of the paper 2 is pressed against the opening 16a of the cultivation container 16, the curved paper pressing member A formed integrally with the lower winding arm 21 also corresponds to the gathering position of the cap opening of the enoki mushroom. The paper 2 is pressed against the side surface of the paper 2 to prevent the upper part of the paper 2 from spreading too much, and the paper 2 is wrapped while the spread of the paper 2 is suppressed in this way. Similarly, the curved upper winding arm 24 moves toward the cultivation container 16, and the curved paper pressing member A and the collar 26
The tip of the paper 2 sequentially comes into contact with the other side of the paper 2, and then, as the other side of the paper 2 is wound around the opening 16a of the cultivation container 16 by the force of the spring 25, a frictional force is applied to the upper winding arm 24 by the bullet 32. The curved paper pressing member A attached and pivotally rotated integrally with the upper winding arm 24 toward the paper 2 side, and presses the side surface of the paper 2 corresponding to the gathering position of the cap opening of the enoki mushroom. is pressed to prevent the upper part of the other side of the paper 2 from spreading too much. When the upper winding arm 24 further rotates while the paper pressing member A presses the paper 2 in this manner, the stopper pin 34 engages with the arm 31 and further presses the arm 31, so that the paper pressing member A further presses the paper 2. The opening is pressed, and in this state, the collar 26 fits into the opening 16a and holds the paper 2. In this way, the paper 2 is wound as shown in FIG. 7 while its spreading is suppressed. In that case, a pair of paper pressing members A
A substantially conical tube shape is formed by the paper holding member B and the paper holding member B, and the side peripheral surface of the paper 2 corresponding to the gathering point of the umbrella opening is shaped and held in a substantially conical tube shape. Further, at the time of return, the upper roll arm 24 and the paper presser member A begin to return together in a closed state, and then the paper presser member A is locked in the collar storage part 29, and the upper roll arm 24
4 rotates toward the lower rear side of the collar storage section 29. Further, the lower winding arm 21 and the paper pressing member A are returned as one unit.

Although the above example shows the case where the paper 2 is fixed by the collar 26, as shown in FIGS.
4 and 21, the paper receiving member A can be expected to have similar effects.

Further, as the operating mechanism of each arm 24, 21 or the interlocking mechanism of the paper receiving member A, a well-known means such as a cam or a cylinder may be used. The paper-rolling arms may be provided in the same manner as in the above-described embodiment, and each paper-rolling arm may be slid along the mouth of the cultivation container by the movement of the piston.

Moreover, although the case where the paper receiving member A is provided integrally with each arm 24, 21 has been shown above, it may be provided separately and an operating mechanism that interlocks with each arm may be provided.

Furthermore, although an arm-shaped paper wrapping member is shown, a paper wrapping member such as a group of rollers presented as a conventional example may also be used. In each of the above-mentioned examples, the cap of the enoki mushroom is 3 to 4 cm from the mouth of the cultivation container.
Although the case where the cap has grown to a certain extent has been described as an example, even if the cap has grown to approximately the same extent as the mouth, it can be stably wrapped around the mouth of the cultivation container in a cylindrical shape.

As described above, this invention takes out a piece of paper from the paper storage section, supplies it to the mouth of a cultivation container, and then uses a pair of wrapping members to spread the paper around the mouth of the cultivation container containing enoki mushrooms. In an automatic paper rolling device for an enoki mushroom cultivation container that is wrapped around and held in a substantially conical tube shape, a paper presser is provided that presses approximately the center of the paper supplied to the mouth of the cultivation container against the mouth, and the paper is fixed by this paper presser. In conjunction with the operation of wrapping both sides of the paper using each wrapping member with reference to the approximately central portion of the paper, the side portion of the paper corresponding to the position where the cap of the enoki mushroom gathers is pressed into an approximately conical tube shape that widens at the end. At least a pair of curved paper pressing members are provided in an inclined shape following the shape of the paper side surface, and the curved paper pressing members slanted following the shape of the paper side surface press the side surface portion of the paper corresponding to the umbrella part assembly position. By pressing the paper into an almost conical tube shape that spreads out at the end and wrapping it while suppressing the spread of the paper, it is possible to automatically wind the paper in a stable conical tube shape. Enoki mushrooms grow in a well-organized state, increasing their commercial value.
