〔Example〕

First, an embodiment of an automatic paper rolling device for an enoki mushroom cultivation container 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 stored upside down, stacked one on top of the other, and is provided so as to be movable forward and backward by a cam control mechanism or the like. In addition, paper storage section 1
A push plate 4 is disposed in which the center portion of the stacked papers 2 is shaped to protrude into a mountain shape, and 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 this 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 opposite 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 operating pin 10 is provided on the base side of the suction cup 7 so as to protrude from the suction cup 7 toward the paper 2 when the suction cup 7 is inclined inward at an angle of 45 degrees. tip 10 of
a 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 cam control mechanism or the like. 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 the paper wrapping location 15
This is a curved paper holder that follows the shape of the opening 16a of the paper holder, and is arranged to be movable forward and backward by a cam control mechanism or the like. 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 the cultivation container 16
This is a retaining member that can hold the paper at the paper wrapping location 15.

A pair of rotating shafts 18 are installed vertically on both sides of the paper-wrapping area 15 where the cultivation container 16 is held, and are rotated back and forth at an appropriate angle by a cam control mechanism. An elastic, curved lower winding arm 21 is pivotally connected to one of the operating rods 19 via a link 20 so as to be swingable about a support shaft 22, and the link 20 and A force directed toward the cultivation container 16 is constantly applied to each of the lower winding arms 21 by a spring 23. 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 recessed groove 27 is formed to accommodate the clip 26, and when the upper winding arm 24 is in a standby state, one clip 26 falls under its own weight and is stored in the recessed groove 27. A clip storage section 29 is disposed above the upper winding arm 24 so that the shutter 28 sometimes works in conjunction with the upper winding arm 24 to prevent the clip 26 from falling under its own weight. Also, each operating rod 1
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 the paper receiving member 9, and a spring (not shown) is attached to the paper receiving member 30 so that the cultivation container 16 is always kept in place. It is given the power to move towards the side.

Therefore, when the paper storage section 1 moves forward by a cam control mechanism or the like, the tip end 10a of the operating pin 10 first moves forward.
The suction cup 7 integrated with the operating pin 10 contacts the outermost paper 2 among the multiple stacked sheets 2, and the operating pin 10 moves outward as the paper storage section 1 moves forward. The suction cup 7 rotates outward, that is, toward the paper surface, against the elastic force of the spring 9, and the suction cup 7 is brought into a substantially horizontal state along the paper surface, and is attracted to the paper 2.

After that, when the paper storage section 1 is moved back by a cam control mechanism or the like, one sheet of paper 2 remains attached to the suction cup 7, and the other sheets of paper 2 are moved back as the paper storage section 1 moves. As 1 retreats, suction cup 7
The paper 2 is returned to its oscillating state at approximately 45 degrees inward due to the elastic force of the spring 9, so that the paper 2 attracted to the suction cup 7 is shaped into a substantially U-shaped curve. 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. 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, the suction cup 7 and the arm 6 side may be moved back and forth instead of 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.

Next, as described above, after taking out a sheet of paper 2 from the paper storage section 1, the arm 6 is moved by the operation of the reversing mechanism 13.
The direction of the paper 2 is changed by almost 180 degrees, and the paper 2 facing upside down is now facing forward, and the paper 2 is supplied to the opening 16a of the cultivation container 16 that has already been supplied to the paper wrapping area 15, and the curved portion 2a of the paper 2 is When the paper presser 14 is moved forward by a cam control mechanism or the like, the curved portion 2a of the paper 2 is pressed against the circumferential surface of the opening 16a of the cultivation container 16, and the cultivation is stopped. The paper 2 is held in a substantially U-shape along the outer peripheral surface of the mouth 16a of the 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 suction cup 7 is
The arm 6 is arranged to move forward and backward, and the sheet of paper 2 is shaped into a curved shape by the forward and backward movement of the arm 6.Then, the arm 6 is further advanced without being reversed to form the cultivation container 1.
Alternatively, the paper 2 may be fed flatly without being shaped into a curved shape, and the feeding 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 arm 21 are moved toward the cultivation container 16. The tip 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.
Then, the upper winding side rotating shaft 18 rotates, the operating rod 19 and the upper winding arm 24 move toward the cultivation container 16, and the end of the clip 26 wraps around the paper so as to smooth out wrinkles or looseness. 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, and both ends of the paper 2 are overlapped vertically, and the wrapping is completed. At the same time, the clip 26 separates from the groove 27 and automatically closes the opening 1.
6a and wrap the paper 2 around it to fix it. In this case, the paper receiving member 30 supports the lower end and upper side 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. 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. Note that the above is just an example of a mechanism for winding both sides of the paper 2 and fixing it with the clips 26.
Although the upper winding arm 24 is formed so as to press directly against the paper 2 and wind it, the upper winding arm 24 may be formed so as to directly press against the paper 2 and wind it, or the clip 26 and the upper winding arm 24 may be pressed against the paper 2 at the same time. They may be wound in contact with each other. In the case of winding the paper, the paper may be wound by the upper winding arm and then the clips may be fitted into the mouth of the cultivation container by operating the individually disposed clip storage section. Alternatively, instead of using clips, fasteners or the like may be provided on both ends of the paper so that when the paper is wound around the mouth of the cultivation container, the two ends of the paper are overlapped and fixed by the fasteners or the like. .

Next, a description will be given of a start switch and a cultivation container transfer mechanism that performs one cycle of paper rolling operations when a cultivation container is brought in.

A transfer table 31 for the cultivation container 16 is arranged on the front side of the paper wrapping section 15, that is, on the opposite side from the paper supply arm 6, and on one side of this transfer table 31, on the carry-in section 15a side, the cultivation container is transferred from a carrying conveyor 32 or the like. 16 is carried in, a lever 33 for operating the start switch A is arranged, one end of this lever 33 is supported by the pivot support 34 on the transfer table 31, and the start switch A faces the tip side of the lever 33. There is.
