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 stacked neatly on both ends, but this allows the enoki mushrooms to be neatly arranged on the inside of the paper wrapped around the cultivation container as they grow. is something that grows. However, if both ends of the paper are not overlapped, it tends to lose its shape, and when the enoki mushrooms grow and extend upwards from the mouth of the cultivation container, the paper loses its shape and may extend outward from the mouth of the cultivation container. There is a risk that enoki mushrooms may grow bent and bent, reducing 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. One that can be clipped and wrapped around has been proposed.

By the way, all of the conventional devices mentioned above are only concerned with simply wrapping the paper around the mouth of the cultivation container, and are not concerned with stably overlapping both sides of the important paper during paper wrapping. This problem has not yet been solved, and as a result, stable automatic winding in a conical shape is still difficult.

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 feed it to the opening of the cultivation container. In a device in which both ends of the paper are overlapped and wrapped by a rear lower winding member and an upper winding member, when returning, the lower winding member slides over the opening of the cultivation container and wraps the overlapping portion of the paper. The present invention includes a return mechanism for a lower winding member that is detached from the lower winding member, and in a state where the lower winding member holds the overlapping portion on one side of the paper, the upper winding member allows the upper winding member to overlap the other side of the paper. In addition, at the time of return, the lower winding member can be detached from and returned to the overlapping portion without damaging the overlapping portion.

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. 1 and 2.

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 a 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 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. Reference numeral 17 indicates a retaining location 15 that can hold the cultivation container 16 at a predetermined location 15.

A pair of rotating shafts 18 are vertically installed on both sides of a predetermined location 55 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 21 are constantly applied with a force directed toward the cultivation container 16 by springs 23 and 23a, respectively. Further, an upper winding arm 24 is pivotally attached to the other operating rod 19 by a support shaft 22a via a spring 25, and this upper winding arm 24 has a substantially C-shaped arm made of an elastic material such as plastic. A concave groove 27 is formed to accommodate the collar 26, and when the upper winding arm 24 is in a standby state, one collar 26 falls under its own weight and falls into the concave groove 27.
When the upper winding arm 24 is operated, the shutter 2 is moved in conjunction with the upper winding arm 24.
A collar storage section 29 is disposed above the upper winding arm 24 so as to prevent the collar 26 from falling under its own weight. Further, on each operating rod 19, a paper receiving member 30 that contacts the lower end of the paper 2 to prevent the paper 2 from sliding down from a predetermined position is attached to a support shaft 30a.
This paper receiving member 30 is pivotally connected by
A force always directed toward the cultivation container 16 is applied by the 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 are moved back along with the movement of the paper storage section 1.
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, and then the paper presser 14 is controlled. When the mechanism moves forward, the curved portion 2a of the paper 2 touches the opening 16 of the cultivation container 16.
The paper 2 is pressed against the circumferential surface 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. Furthermore, in the above explanation, the arm 6 of the suction cup 7 is reversed and supplied to the opening 16a of the cultivation container 16, but the arm 6 of the suction cup 7 is The sheet of paper 2 is arranged to move forward and backward, and after shaping a sheet of paper 2 into a curved shape by forward and backward movement of the arm 6, the arm 6 is further advanced without being reversed and fed to the opening 16a of the cultivation container 16. The supply structure may be changed as appropriate.

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 tip of the curved lower winding arm 21 contacts the paper 2, and then the force of the springs 23, 23a and the link 2
0, one side of the paper 2 is pressed and slid against the opening 16a of the cultivation container 16, and is gradually wound so as to smooth out wrinkles or loose parts.Then, the upper winding side rotating shaft 18 rotates and the operating rod is rotated. 19 and upper winding arm 24
moves toward the cultivation container 16 side, the end of the collar 26 contacts the other side of the paper 2, and then the force of the spring 25 causes the other side of the paper 2 to stretch out wrinkles etc. along the opening 16a of the cultivation container 16. The paper 2 is wound so that both ends of the paper 2 are stacked vertically, and at the same time as the winding is completed, the collar 26 separates from the groove 27 and automatically fits into the opening 16a to wrap and fix the paper 2.
In that case, the lower winding arm 21 and the upper winding arm 2
4, a pair of paper receiving members 30 support the lower end of the paper 2.

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, after taking out a piece of paper 2 from the storage section 1 and supplying it to the opening 16a of the cultivation container 16, the lower winding arm 2
1 and an upper winding arm 24 for sequentially overlapping and winding the overlapped portions 2a and 2b on both sides of the paper 2, one end of the link 20 is rotatably connected to an operating rod 19 operated by a rotating shaft 18. , a lower winding arm 2 is attached to the other end of the link 20.
1 is pivotally attached to the cultivation container 16 by a support shaft 22, and the link 20 and the lower-rolling arm 21 are constantly applied with a force directed toward the cultivation container 16 by springs 23 and 23a, so that the lower-rolling arm 21 is attached to the cultivation container 16 at the time of return. The system is equipped with a recovery mechanism A for the lower winding arm 21, in which the arm 21 slides on the opening 16a of the cultivation container 16 and detaches from the overlapping parts 2a and 2b of the paper 2, as shown in FIG. As shown in B, when the operating rod 19 is actuated by the rotating shaft 18, the link 20 is moved against the force of the spring 23 to move the lower winding arm 21.
The lower winding arm 21 swings around the support shaft 22 while resisting the force of the spring 23a, slides on the opening 16a, and wraps one side of the paper 2 while pressing against the opening 16a. In this state, as shown in FIG. 3C, the overlapping portion 2b on the other side of the paper 2 is wound and held by the upper winding arm 24 in an overlapping state,
Next, as shown in FIGS. 3D and 3E, when the rotating shaft 18 is reversely rotated with the upper winding arm 24 holding the overlapping parts 2a and 2b, the operating rod 19 moves backward, but the lower winding arm 21 is moved by the spring 23a. The mouth part 16 swings around the support shaft 22 due to the force of
a slides to come out of the overlapped portions 2a, b, thereby placing relatively less stress on the overlaps 2a, 2b, and returns to the state of wrapping in a good manner.

Although the case in which the operating rod 19 and the link 20 are used has been described above, the lower winding arm 21 is attached to the piston 32a of the cylinder 32 whose base end is rotatably provided by a support shaft 31 as shown in FIG. The lower winding arm 21 is provided in the same manner as in the embodiment, and the movement of the piston 32a causes the lower winding arm 21 to move onto the support shaft 22 via the spring 23a.
It may be configured to slide along the mouth portion 16a while swinging around the center. In that case, in FIG. 4, 33 is the tension spring of the cylinder 32;
4 is a stopper.

As described above in this invention, after a piece of paper is taken out from the paper storage section and supplied to the mouth of the cultivation container, both sides of the paper are overlapped and wrapped by the lower winding member and the upper winding member. , the lower winding member is equipped with a return mechanism for the lower winding member that slides on the opening of the cultivation container and separates from the overlapping part of the paper when returning, so that the paper is important when rolling the paper. The automatic winding of the overlapping parts of both ends becomes stable, and when the enoki mushroom grows, the enoki mushroom grows in an orderly state on the inside of the paper wrapped in the cultivation container, and the commercial value of the enoki mushroom is increased.
