Description

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a fan-shaped paper made of paraffin paper or the like is placed at the mouth of an enoki mushroom cultivation container in consideration of hygroscopicity, air permeability, and the strength of the paper itself. This invention relates to an automatic paper rolling device for automatically winding paper according to growth.

A fan-shaped paper is wrapped in a conical shape around the mouth of the enoki mushroom cultivation container, and the enoki mushrooms are grown in a well-organized state on the inside of the wrapped paper. As disclosed in Japanese Utility Model Publication No. 58-1173, paper having fasteners on both ends is manually wrapped, but this is very inefficient and is not a labor-saving method. Moreover, this work is done in a room with a temperature of around 4 degrees Celsius, which could be harmful to the health of the workers. By the way, a device in which paper is automatically wrapped around the bottle opening and fixed by a collar is known from Japanese Patent Application Laid-open No. 138332/1983.
However, in the case of fixing paper with a collar, an expensive collar separate from the paper must be fitted into the bottle opening after the paper is rolled, making the device complicated and expensive, and requiring a large number of collars, resulting in high costs. There is a problem. Compared to this, the use of paper with a fastener has the advantage of being cheaper and of being able to fix the paper with the fastener that is integrated with the paper. However, in order to automatically wrap paper with fasteners, it is necessary to wrap the paper so that the fasteners on both sides of the paper correspond accurately, but the fasteners on both sides of the paper tend to shift due to wrinkles or loosening of the paper, making automation difficult. It was difficult.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide an automatic paper wrapping device for an enoki mushroom cultivation container that can automatically wrap and fix paper with a fastener, thereby solving the above-mentioned problems. The structure consists of a paper provided with fasteners on both ends to be wrapped around the mouth of the cultivation container, a paper storage section for storing the paper provided with the fasteners, and a paper storage section for storing the paper provided with the fasteners, and a paper storage section for storing the paper provided with the fasteners. The paper feeding mechanism is provided with a paper feeding mechanism that feeds the paper to the mouth of the cultivation container, and fixes approximately the center of the paper supplied to the mouth of the cultivation container to the mouth with a paper presser, and both sides of the paper are fixed based on the approximately center of the fixed paper. A pair of curved paper wrapping members for wrapping paper are horizontally rotatably connected to an actuating member that horizontally moves the paper wrapping members toward the mouth, and the actuating member is fixed to the rotating member. The purpose of this is to urge the tip end of the mouth toward the mouth side using a spring.

Next, an example based on the above characteristics is shown in FIGS. 1 to 5.
This will be explained using figures.

A mechanism for suctioning and taking out a piece of paper from a paper storage section that accommodates paper provided with a fastener will be explained.

Reference numeral 1 designates a paper storage unit in which a large number of fan-shaped papers 2 each having a fastening fastener 2a provided at least in the overlapped portions of both ends are stacked vertically and stored upside down, as shown in FIG. 1. It is provided so that it can be moved forward and backward by a mechanism. Further, the paper storage section 1 is provided with a push plate 4 which can shape the central part of the stacked papers 2 to protrude into a mountain shape and which can press and hold a spring 3 with elastic force according to the amount of the 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 given a spring force by a spring 9 so as to swing inward at all times, and is held by a stopper (not shown) in a state inclined inward at approximately 45 degrees. ing. 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 tilted inward at approximately 45 degrees. 10 tips 10
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 angle may be changed as appropriate as long as it is inclined inward. 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 arm 6 side may be made movable in advance and retreat, 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, a mechanism for feeding this paper to the mouth of the cultivation container will be explained.

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 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.
Note that the suction cup 7 is moved forward by the paper presser 14 (not shown).
The negative pressure generator is turned off and turned on by reversing.

Therefore, after the paper 2 is taken out from the paper storage section 1, the arm 6 changes its direction by approximately 180 degrees by the operation of the reversing mechanism 13, and the paper 2, which was oriented upside down, is now oriented in the forward direction, and the paper 2 is moved manually or by an appropriate feeding mechanism (not shown) to a predetermined position. The paper 2 is supplied to the opening 16a of the cultivation container 16 that has already been supplied to the 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 touches the cultivation container 16 and the opening 1.
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. Also, in the upside-down 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.The arm 6 of the suction cup 7 is arranged so as 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. The sheet of paper 2 may be shaped into a curved shape by forward and backward movements, and then the arm 6 may be moved to feed it to the opening 16a of the cultivation container 16, and the feeding configuration may be changed as appropriate. . 1
Reference numeral 7 denotes a retaining member that can hold the cultivation container 16 at a predetermined location 15.

Next, a mechanism for winding the paper supplied to the mouth of the cultivation container and fixing it with a fastener provided on the paper will be explained.

On both sides of a predetermined location 15 where the cultivation container 16 is held, a pair of rotating shafts 18, which are a pair of rotating members that reciprocate at an appropriate angle by a control mechanism, are installed vertically. An operating rod 19, which is an operating member that horizontally moves the paper wrapping member toward the mouth portion 16a, is fixed thereto, and a curved lower winding member, which is an elastic paper wrapping member, is attached to one of the operating rods 19 via a link 20. Arm 21
is pivotally attached to the link 20 and the lower arm 21 by a support shaft 22, and the tip side of the lower arm 21 is connected to the opening 16 of the cultivation container 16.
A spring 23 is provided that biases toward the a side. Further, an upper winding arm 24 serving as a paper wrapping member is pivotally attached to the other operating rod 19 via a support shaft 22a, and the upper winding arm 24
A spring 25 is provided that biases the tip side of the cultivation container 16 toward the opening 16a of the cultivation container 16.

Further, a paper receiving member 26 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 27, and this paper receiving member 26 is constantly applied with a force directed toward the cultivation container 16 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 26a that prevents the upper side of the paper 2 from expanding outward.

Therefore, 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 and the link 20 are rotated.
Then, the lower winding arm 21 moves toward the cultivation container 16, and the tip of the curved lower winding arm 21 comes into contact with 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 moved toward the cultivation container 16. The upper winding side rotating shaft 18 rotates and the operating rod 19 and upper winding arm 24 move toward the cultivation container 16. The tip of the upper winding arm 24 contacts the other side of the paper 2, and then the paper 2 is lifted by the force of the spring 25.
Wrap the other side along the opening 16a of the cultivation container 16 so as to smooth out the wrinkles, and overlap both ends of the paper 2 vertically to ensure that the fasteners 2a provided at the overlapped portions of the paper 2 are secured to each other. Glue and fix. In that case, the paper receiving members 26, 26a are linked to the lower winding arm 21 and the upper winding arm 24.
supports the lower end and upper side 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 this embodiment, the paper storage unit 1 moves forward and the paper 2 is attracted to the suction cup 7 while the cultivation container 16 is being supplied to the predetermined location 15 as shown in FIG. 4A. Then, as shown in FIG. 4B, the paper storage section 1 is moved back and a piece of paper 2 is left in a curved shape on the suction cup 7. In this case, the paper presser 14 and each arm 24, 21 have completed their return. After that, the arm 6 is reversed as shown in FIG.
As shown in FIG. D, the paper presser 14 moves forward to press the paper 2 against the circumferential surface of the opening 16a of the cultivation container 16, thereby holding the paper 2 in a U-shape. Further, as shown in FIGS. 4E and 4F, the lower winding arm 21 moves and begins to wind 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. Thereafter, as shown in FIG. 4G, one side of the paper 2 is squeezed into the opening 16a of the cultivation container 16 by the lower winding arm 21, and the lower winding operation is completed. Thereafter, as shown in FIG. 4H, the other side of the paper 2 comes into contact with the upper winding arm 24 by movement of the upper winding arm 24 and begins to be rolled up, and then the other side of the paper 2 is narrowed and the upper winding operation is performed as shown in FIG. 4I. When this is completed, both ends of the paper 2 are overlapped, the winding of the paper 2 is completed, and the overlapping portion is fixed by the fastener 2a. FIGS. 4J and 4K show the 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 paper 2 provided with the fastener 2a is not limited to the one shown in FIG.
It is also possible to use one having a knob as in Japanese Patent No. 58-1173. In the above-mentioned embodiment, the paper stored in the storage section is sucked by the suction member and fed to the mouth of the cultivation container. May be used.
Note that the winding mechanism is not limited to the above-mentioned embodiments, and may be implemented by any suitable winding mechanism.

In this way, the present invention provides a paper for wrapping around the mouth of a cultivation container provided with fasteners on both ends, a paper storage section for storing the paper provided with the fasteners, and a paper storage section for storing the paper provided with the fasteners in the cultivation container. and a paper feeding mechanism that feeds the paper to the mouth of the cultivation container, and fixes approximately the center of the paper supplied to the mouth of the cultivation container to the mouth with a paper presser, and then feeds the paper with reference to the approximately center of the fixed paper. A pair of curved paper wrapping members for wrapping both sides are horizontally rotatably pivoted to an actuating member that horizontally moves the paper wrapping members toward the mouth;
The actuating member is fixed to the rotating member, and the tip side of each paper wrapping member is biased toward the mouth side by a spring, so that the tip side of the paper wrapping member is pushed through the actuating member by the rotational drive of the rotating member. By moving toward the opening, coming into contact with the paper, and sliding elastically under the force of the spring, it is possible to automatically wrap the paper with the fastener in a state where wrinkles or loose parts are stretched out. As a result, the fasteners on both sides of the paper are accurately overlapped and fixed, making it possible to perform automatic paper winding at low cost and efficiency, which is highly effective.
