Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an automatic paper wrapping device for automatically wrapping a fan-shaped paper around the mouth of an enoki mushroom cultivation container according to the growth of the fruiting bodies of enoki mushrooms. . Furthermore, the paper wrapped around the mouth of the enoki mushroom cultivation container is generally made of paraffin paper or the like, taking into account moisture absorption, air permeability, and the strength of the paper itself.

[Prior Art] As a conventional device of this kind, Japanese Patent 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. 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 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 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 topmost paper in the stack is held by suction, one end of the paper is fed upright to a guide position provided close to the mouth of the container, and an endless belt stretched around a pulley is moved. It is wrapped around the mouth of the container.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, the paper is fed to the mouth in a flat state and wrapped by the movement of a belt. Although it is rare, this paper is used repeatedly dozens of times, and as the number of uses increases, the paper may become warped or deformed. If the portion is deformed or bent, the paper may shift vertically or be tilted, making it difficult to wrap the paper around the opening of the container. On the other hand, JP-A-51-
In Japanese Utility Model Publication No. 126665, Japanese Utility Model Publication No. 54-34944, and Japanese Utility Model Publication No. 48-43443, a device has been proposed in which paper, etc. in a storage section is shaped into a curved shape and taken out, and this device is applied to the above-mentioned conventional technology. However, the problem is that the paper that is taken out from the paper storage section in a curved shape becomes flattened by the time it is fed to the mouth of the cultivation container, resulting in the paper shifting and tilting as described above. There is.

Therefore, the present invention provides an automatic paper winding device for an enoki mushroom cultivation container, which can supply paper to the mouth of the cultivation container in a curved state, and can wrap not only new paper but also paper that has been used many times. The purpose is to

[Means for Solving the Problems] The present invention takes out a piece of paper from a paper storage section, supplies it to the opening of a cultivation container located in a container supply section, and then wraps the paper around the opening of the cultivation container and holds it. The automatic paper rolling device for the enoki mushroom cultivation container includes a suction member that suctions and takes out a piece of paper from a paper storage section, a paper shaping mechanism that holds the suctioned paper in a curved shape, and a paper shaping mechanism that holds the suctioned paper in a curved shape. a paper supply mechanism that rotates and moves the paper shaping mechanism about a support shaft so as to supply the paper to the mouth of the cultivation container while still being shaped into a curved shape; The paper storage section and the container supply section are provided.

[Example] Next, an example based on the above characteristics is shown in Figs.
This will be explained using figures.

A suction member A that suctions and takes out a sheet of paper from a paper storage section and a paper shaping mechanism B that holds this suctioned paper will be described.

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 held between the push plate 4 and a pair of stoppers 5 provided on both side walls of the paper storage section 1.

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 operating 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 toward the paper 2 when the suction cup 7 is inclined inward at approximately 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.

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 tip 10a of the actuating pin 10 slides against the paper 2 and moves outward as the paper storage section 1 moves forward, the suction cup 7 integrated with the actuating pin 10 is moved by the spring 9.
The suction cup 7 rotates outward, that is, toward the surface of the paper, against the elastic force of the suction cup 7, and the suction cup 7 becomes in a substantially horizontal state parallel to the surface of the paper, and sucks 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 made movable to move 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, an example of the paper supply mechanism C that rotates and moves with the paper shaping mechanism B as a fulcrum so as to supply the paper to the mouth of the cultivation container while still being shaped into a curved shape will be explained. do.

Reference numeral 11 denotes a reversing shaft which is a supporting shaft to which the base of the arm 6 to which the suction cup 7 is attached is fixed, and a pair of left and right receiving plates 12
It is centered on. This reversing shaft 11 is provided with an appropriate reversing mechanism 13 operated by a control mechanism (not shown). In this case, in the drawing, a rack 13b is disposed in mesh with a pinion 13a provided on the reversing shaft 11, and the arm 6 is moved up and down by the raising and lowering movement of the rack 13b.
Although the pinion rack is formed so as to be inverted, a rotary actuator (not shown) or the like may be used instead of the pinion rack.

14 is the cultivation container 1 supplied to the container supply section 15
This is a curved paper presser that follows the shape of the opening 16a of No. 6, 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.

Therefore, after a piece of paper 2 is taken out from the paper storage section 1 while being shaped into a curved shape by the suction member A and the paper shaping mechanism B, the arm 6 is rotated around the inversion shaft 11 as a supporting shaft by the operation of the reversing mechanism 13. almost 180
After the paper 2 is turned upside down and turned upside down, the paper 2 is fed manually or by an appropriate feeding mechanism (not shown) to the opening 16a of the cultivation container 16 that has already been fed to the container feeding section 15. The curved portion 2a of the paper 2 is arranged so as to correspond to the curved shape of the opening 16a, and when the paper presser 14 is moved forward by the control mechanism, the curved portion 2a of the paper 2 is arranged to correspond to the curved shape of the opening 16a of the cultivation container 16. The paper 2 is held in a substantially U-shape along the outer peripheral surface of the opening 16a of the cultivation container 16. In addition, in the above explanation, the arm 6 of the suction cup 7 is inverted and the opening 1 of the cultivation container 16 is
As shown in FIG. 5, 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 a normal state, and the movement of the arm 6 back and forth moves the paper 2 into the paper storage section 1. After shaping the sheet of paper 2 into a curved shape, the paper shaping mechanism B is horizontally rotated 90 degrees around the support shaft 11A to move the paper 2 while holding the paper 2 in a curved shape in the opening 16a of the cultivation container 16. Alternatively, the supply structure may be changed as appropriate.

Next, an example of the mechanism D for winding the curved paper supplied to the mouth of the cultivation container and fixing it with a collar will be described.

A pair of rotating shafts 18 are vertically installed on both sides of the container supply unit 15 in which the cultivation container 16 is held, and are rotated back and forth at an appropriate angle by a control mechanism.
An operating rod 19 is installed on the upper part of each of the operating rods 19, and an elastic, curved lower winding arm 21 is pivotably pivoted to one of the operating rods 19 via a link 20 by a support shaft 22. 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. In addition, an upper winding arm 24 is connected to the other operating rod 19 via a spring 25 on the support shaft 2.
A groove 27 is formed in this upper winding arm 24 to accommodate 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). Further, the lower winding arm 21 and the upper winding arm 24 are each provided with a curved paper receiving member 30a that prevents the upper side of the paper 2 from expanding outward.

Therefore, the curved paper 2 is fed by the paper supply mechanism C.
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, and a curved shape is formed. The tip of the 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 pressed against the opening 16a of the cultivation container 16 and pulled to smooth out the wrinkles. Gradually wind it while tensioning it, then the upper winding side rotating shaft 18 rotates and the operating rod 1
9 and the upper winding arm 24 move toward the cultivation container 16, the end of the collar 26 contacts the other side of the paper 2, and then the other side of the paper 2 is moved along the opening 16a of the cultivation container 16 by the force of the spring 25. The collar 26 is pulled out from the concave groove 27 and automatically wrapped around the paper 2 so that both ends of the paper 2 are stacked one above the other.
a and wrap the paper 2 around it to fix it. In this case, the paper receiving members 30 and 30a support 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, 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.
6 is merely an example of the mechanism D that fixes the paper 2. 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 is formed so that it presses directly against the paper 2 and winds it. Alternatively, the collar 26 and the upper winding arm 24 may be pressed against the paper 2 and wound at the same time. In addition, when wrapping the paper, the collar may be fitted into the mouth of the cultivation container by winding the paper using the lower arm and the upper arm, and then operating the separately arranged collar storage section.

Therefore, in this embodiment, when the cultivation container 16 is being supplied to the container supply section 15 as shown in FIG. 3A, the paper storage section 1 moves forward and the suction cup 7
Paper 2 is adsorbed to. Next, as shown in FIG. 3B, the paper storage section 1 is moved back, and a piece of paper 2 is left in a curved shape on a suction cup 7 attached to the arm 6. In this case, the paper presser foot 14 and the upper and lower winding arms 24, 21 have each completed their return. Thereafter, as shown in FIG. 3C and the dashed-dotted line in FIG. The curved paper 2 is transferred and held in such a way that the curved portion 2a of the paper 2 is positioned. Next, press paper presser 1 as shown in Figure 3D.
4 moves forward and presses the paper 2 against the circumferential surface of the opening 16a of the cultivation container 16 to hold the paper 2 in a U shape. Furthermore, the third
As shown in Figures E and F, the center of the curved paper 2 is the opening 16.
The lower winding arm 21 moves while being positioned at point a and begins winding one side of the paper 2 around the mouth portion 16a. In this case, the arm 6 of the suction cup 7 is in the middle of returning. After that, as shown in Fig. 3G, the unwinding arm 21
As a result, about 1/3 of the length of one side of the paper 2 is squeezed into the opening 16a of the cultivation container 16, and the lowering operation is completed.
Thereafter, as shown in FIG. 3H, by the movement of the upper winding arm 24, approximately 1/3 of the length of the other side of the paper 2 comes into contact with the collar 26 and begins to be rolled up, and then the other side of the paper 2 is narrowed down, as shown in FIG. As shown in I, the upper winding operation is completed and paper 2
Both ends of the paper 2 are overlapped, the winding of the paper 2 is completed, and the paper 2 is fitted and fixed by the collar 26. Figure 3 J,
K indicates a subsequent state in which the arms 24 and 21 are returning, and in this case, the paper storage section 1 has started moving forward. Note that the above-mentioned operating conditions over time may be changed as appropriate. Further, the above-mentioned control mechanism (not shown) may be driven by a known control means such as a cam or a cylinder.

In this way, in the above embodiment, a sheet of paper 2 is taken out from the paper storage section 1 by suction by the suction member A, and is also shaped into a curved shape by the paper shaping mechanism B, and the curved shaped state is maintained. Support shaft 1
The cultivation container 1 which has already been supplied to the container supply unit 15 by rotating the paper shaping mechanism B using 1 and 11A as a fulcrum
Since it is possible to transfer and hold the paper 2 in a curved state to the opening 16a of the paper 2, it is possible to accurately transfer both sides of the paper 2 with the central curved part 2a of the paper 2 positioned at the opening 16a. It is possible to wrap the paper 2 along the opening 16a, and since it is only necessary to wrap each side of the paper 2 by about 1/3 of the length, it is possible to further prevent the paper 2 from slipping. Therefore, compared to the conventional method of wrapping paper in a flat state, even if the paper 2 has been used many times, the curved portion 2a of the paper 2 can be aligned with the curved shape of the opening 16a. As a result, there is no shift or inclination of the paper 2, and both sides of the paper 2 can be wrapped well along the opening 16a of the container 16. Further, since the paper shaping mechanism B is rotated and moved about the support shafts 11 and 11A, the paper 2 is fed with high accuracy and accurate winding is performed. Further, since the paper storage section 1 and the container supply section 15 can be arranged around the support shafts 11 and 11A, the apparatus becomes compact.
