Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to an automatic paper wrapping device for automatically wrapping paper around the mouth of an enoki mushroom cultivation container, and more specifically, an automatic paper wrapping device for automatically wrapping paper around the mouth of an enoki mushroom cultivation container, and more specifically, an automatic paper winding device for automatically wrapping paper around the mouth of an enoki mushroom cultivation container. The collars are arranged in a stacked state, and a piece of paper is taken out from the paper storage section and supplied to the mouth of the cultivation container, and then the paper is wrapped around the mouth of the cultivation container by a paper wrapping member, and the paper is supplied from the collar storage section. This invention relates to an automatic paper wrapping device for an enoki mushroom cultivation container, in which the collars are taken out one by one by a mechanism, the collars are fitted into the mouth of the container, and paper is wrapped around the container to hold it.

[Conventional technology]

After wrapping paper around the opening of the cultivation container using a paper wrapping device, a collar is press-fitted onto the opening of the cultivation container using a wrapping paper fixing mechanism.
It has been proposed as Publication No. 55-42801. This collar fitting means has a U-shaped notch in the driving plate,
A recess into which a single collar can be placed is formed at the periphery of the U-shaped notch, and the collar is positioned and held by the recess so as to be driven into the collar.

[Problem that the invention seeks to solve]

When the U-shaped notch fits into the mouth of the cultivation container due to the driving operation of the driving board, the tip of the collar held in the recess snaps elastically along the outer diameter of the mouth of the container. It expands and then narrows to be held approximately along the mouth of the container. At this time, the opening side of the concave part needs to be formed with an opening width larger than the maximum width of the collar in consideration of the elastic expansion of the collar, and for this reason, the positioning of the collar by the concave part must avoid insufficient surfaces. This has the disadvantage that the collar tends to become unstable as the driving plate moves, causing problems in the fitting of the collar.

[Means for solving problems]

The feature of the present invention is that elastic, approximately C-shaped collars are arranged in a stacked manner in the collar storage section, and after taking out a piece of paper from the paper storage section and supplying it to the mouth of the cultivation container, the paper is wrapped in paper. The material is wrapped around the mouth of the cultivation container, the collars are taken out one by one from the collar storage section by the supply mechanism, the collar is fitted onto the mouth of the container, and paper is wrapped around the container to hold it. , a collar mounting member arranged to be movable horizontally between the mouth of the cultivation container and the collar housing;
The collar supply mechanism includes a collar fixing mechanism provided on the placement member to fix the collar, and a collar fixation release member that releases the fixation of the collar at least when the collar placement member is located in the collar storage section. It is in.

[Effect]

Since the collar placed on the collar mounting member is driven in a fixed state by the collar fixing mechanism, the collar can be securely fitted to the mouth of the cultivation container in a stable state, and the collar mounting member can be inserted into the collar storage section. Since the collar is released from the fixed state when positioned, there is no need to worry about interfering with the supply of collars.

〔Example〕

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). Further, the paper storage section 1 is provided with a push plate 4 that shapes the central portion of the stacked papers 2 so as to protrude into a mountain shape, and that can be pressed and held by the elastic force of the spring 3 according to the amount of the 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 is bent outward. Further, a negative pressure generating device (not shown) such as a vacuum pump is connected to the suction cup 7. 11
is 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 drawing, a rotary actuator (not shown) is used without using a pinion rack, in which 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. Ether etc. 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 21 are constantly applied with a force directed toward the cultivation container 16 by a spring 23. A curved upper winding arm 24 is pivotally attached to the other operating rod 19 by a support shaft 22a via a spring 25, and the upper winding arm 24 side is made of an elastic material such as plastic. The approximately C-shaped collar 26 is connected to the opening 16 of the container 16.
A supply mechanism 27, which will be described later, is formed to supply the upper winding arm 24 toward the upper winding arm 24. When the upper winding arm 24 is in a standby state, one collar 26 falls under its own weight, and the upper winding arm 24 falls to the above-mentioned supply mechanism 2.
7, and when the upper winding arm 24 is operated, the shutter 28 is interlocked with the upper winding arm 24 to prevent the collar 26 from falling due to its own weight. It is set up. 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, and this paper receiving member 30 A spring always applies a force toward the cultivation container 16 side.

Therefore, when the paper storage section 1 moves forward by an appropriate control mechanism, the tip of the operating pin 10 first contacts the outermost paper 2 among the multiple stacked sheets of paper 2, and the paper storage section 1 is moved forward. Operating pin 10 as it moves forward
moves outward, so the suction cup 7 integrated with the operating pin 10 rotates outward, toward the paper surface, against the elastic force of the spring 9, and the suction cup 7 becomes almost horizontal, aligned with the paper surface. Adsorbs to 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 part 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, paper 2
The curved portion of is pressed against the circumferential surface of the opening 16a of the cultivation container 16, and 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 paper 2.
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. Then, the tip of the curved lower winding arm 21 comes into contact with the paper 2,
Next, by the force of the spring 23 and the action of the link 20, one side of the paper 2 is attached to the opening 16 of the cultivation container 16.
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 upper winding arm 24 moves to the cultivation container 16 side to wrap the collar 26. The end is paper 2
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 wrinkles or slack, so that both ends of the paper 2 are stacked vertically, and the wrapping is done. At the same time, the collar 26 separates from the supply mechanism 27 and automatically fits into the opening 16a to wrap and fix the paper 2.

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. Further, in the above description, a type in which the collar is fitted while wrapping the paper is shown, but a type in which the collar is fitted after the paper is wound may also be used.

By the way, in this invention, the means for supplying and fitting the collar 26 is a flat collar mounting device arranged so as to be able to reciprocate in the horizontal direction between the opening 16a of the cultivation container 16 and the storage section 29 of the collar 26. Member 31
a collar fixing mechanism A that is attached to this mounting member 31 and fixes the collar 26; and a collar fixing release member B that releases the fixation of the collar 26 at least when the collar mounting member 31 is located in the collar storage section 29. The collar mounting member 3
The collar 26 placed on the collar 26 is fixedly driven by the collar fixing mechanism A, and the collar 26 placed on the collar mounting member 31
As the collar 26 returns to its original state, the collar 26 is fitted and held in the opening 16a of the cultivation container 16, and when the collar mounting member 31 is located in the collar storage section 29, the collar fixing mechanism A is released, and the collar storage section 29
One collar 26 is placed on the placing member 31.

More specifically, FIGS. 3 to 7 show the first embodiment, in which a first fixing member 32 is formed protruding from the upper surface of the base end of a flat collar mounting member 31 cut out in an approximately U-shape. At the same time, an L-shaped second fixing member 33 is provided on the upper part of the collar mounting member 31 by a pivoting part 34 so as to be rotatable in the horizontal direction, so that both fixing members 32,
33 forms a fixing mechanism 35 for the collar 26. The proximal end of the second fixing member 33 and the collar mounting member 31 are connected by a tensioning bullet 36 to apply a rotational force to the second fixing member 33 toward the first fixing member 32. are doing. Also color 2
At the base end of 6, there is a protrusion 3 which is narrowly fixed by the first and second fixing members 32 and 33 toward the rear.
7 is formed. Further, on the side of the collar storage section 29, as shown in FIG. A collar fixing release member 38 is provided to prevent rotation of the first fixing member 32 against the rotation of the first fixing member 32. 39 is a restraining wall of the second fixing member 33.

Therefore, the protrusion 37 of the collar 26 placed on the collar mounting member 31 is connected to the fixing members 32, 3.
3. Next, as the supply mechanism 27 moves, the second collar is released from the collar fixing release member 38.
The fixing member 33 is detached, and as a result, the tensile force of the bullet 36 acts, and the rotational force of the second fixing member 33 causes the protrusion 37 to move between the first and second fixing members 32, 33.
caught between. In this state, the supply mechanism 2
7 moves toward the opening 16a of the cultivation container 16, the collar 26 is fitted into the opening 16a of the cultivation container 16, and as the supply mechanism 27 returns, the collar 26
Since the fitting force to the opening 16a of the collar 26 is greater than the fitting force to the protrusion 37 of the fixing mechanism 35, the collar 26
is left fitted and held in the mouth portion 16a, and the second fixing member 33 is rotated by the force of the bomb 36 and engaged by the restraining wall 39 when the collar 26 is not placed, as shown by the dashed line in FIG. It reaches the lower part of the collar storage part 29 while remaining in the stopped state. Then, the second fixing member 33 engages with the collar fixing release member 38 and returns to the state shown by the solid line in FIG. 3 against the force of the bullet 36, and one collar 26 is placed from the collar storage section 29. It falls onto the member 31. Next, the supply mechanism 27
As the collar release member 38 separates from the second fixing member 33 due to the feeding operation, the second fixing member 33 is rotated by the force of the bullet 36, and the protrusion 37 of the collar 26 is clamped and fixed by the fixing mechanism 35. Then, the same operation as described above is repeated.
