Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides hygroscopic properties at the mouth of the enoki mushroom cultivation container.
An automatic paper wrapping device that automatically wraps a fan-shaped paper made of paraffin paper or the like according to the growth of the fruiting body of an enoki mushroom, taking into consideration breathability or the strength of the paper itself. The present invention relates to an automatic paper winding device equipped with means that can take out paper well.

Conventional devices of this type have been proposed in Japanese Patent Laid-Open Nos. 124426/1982 and 124428/1982.
This involves suctioning and taking out the papers one by one from the paper storage section using a suction cup and dropping them onto the feeding route of the cultivation container, and then feeding the cultivation container into the feeding route via a flexible wire and dropping it under its own weight. By pressing against the paper, the paper is bent to follow the shape of the mouth of the cultivation container.

However, in the above-mentioned device, the suction cup is simply pressed against the paper to attract it and then taken out in the same direction as the stacking direction of the papers, so multiple sheets of paper may be drawn in and taken out at the same time. This makes automatic paper rolling difficult.
In particular, this type of paper may have many vertical lines formed to strengthen the paper, and especially in the case of new paper, it is manufactured by stacking many sheets and punching them. Therefore, these vertical stripes may overlap and be difficult to separate, making it even more noticeable that multiple sheets of paper are being drawn in. Also, JP-A-56-
In Japanese Patent No. 4524, it has been proposed to take out cut pieces of a folding box stored in a stationary magazine using a suction member provided on a rotating support via a square link. The suction member is pressed against and adsorbed, and then the suction member is moved backward in the same direction as the overlapping direction of the shredded pieces under the control of the square link to take out a plurality of shredded pieces at the same time. A sheet of shredded pieces is easily drawn in and taken out, and for this reason, a holding mechanism and a slider are provided on the magazine side, and the slider pushes and moves one of the shredded pieces from the direction of its thickness and removes it from the holding mechanism, The shredded pieces are taken out one by one, requiring complicated devices such as the holding mechanism and slider. Furthermore, in Japanese Patent Application Laid-open No. 56-131108, it has been proposed to take out the paper stored in the paper loading device using a suction member, but in this method the paper is pushed forward by a push plate. The suction member is pressed against the paper at the forefront of the paper to attract it, and in this state, the suction member is moved at appropriate intervals in the same direction as the stacking direction of the paper and taken out. The paper is easily drawn in and taken out, so an air jet device for fanning the paper in the feeding direction after taking out and a wedge-shaped feed regulating member are separately provided, resulting in a complicated structure. I was getting used to it.

In view of the above circumstances, it is an object of the present invention to solve the above-mentioned drawbacks by providing an automatic paper winding device equipped with a means for reliably taking out paper sheets one by one. In this device, a sheet of paper is sucked and taken out, and is also supplied to the mouth of the cultivation container and wrapped around and held. The present invention is to include a paper separation mechanism capable of moving at least one of the suction member side and the paper storage section side in a vertical direction substantially perpendicular to the stacking direction of the sheets.

Next, embodiments of the present invention will be described with reference to illustrative drawings.

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 stacked vertically and stored upside down, and is provided to a cam control mechanism or the like so as to be movable forward and backward via a rail 1a. 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.
Further, a pair of left and right paper receivers 1b are arranged at the bottom 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. 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 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, a paper receiving member 30 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, and a spring (not shown) is attached to the paper receiving member 30. Therefore, a force always directed toward the cultivation container 16 side is applied.

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 the inward swinging state at approximately 45 degrees due to the elastic force of the spring 9, so that the paper 2 sucked by the suction cup 7 is shaped into a roughly 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. In addition, the paper storage section 1 is provided with a push plate 4 formed into a protruding mountain shape to facilitate suction, but paper 2 is stacked and arranged along the push plate 4 formed flat, and this paper 2 is The suction may be performed using a flat suction cup 7. 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, 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 adsorbed by the forward and backward movement of the arm 6, and the arm 6 is further advanced without being reversed and shaped into a curved shape at the opening 16a of the cultivation container 16. Alternatively, 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, 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.
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 collar 26 wraps around the paper so as to press against it and smooth out wrinkles or bends. 2, and then by the force of the spring 25, the paper 2
Wrap the other side of the paper 2 along the opening 16a of the cultivation container 16 so as to smooth out the wrinkles, overlapping both ends of the paper 2 vertically, and as soon as the wrapping is finished, remove the collar 2.
6 detaches from the groove 27 and automatically fits into the opening 16a to wrap and fix the paper 2. 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. The above is just an example of a mechanism for fixing both sides of the paper 2 with the winding collars 26. In the above explanation, the collars 26 are formed so as to press directly against the paper 2 and wind it, but the upper winding arm 24 is It may be formed so as to be pressed directly against the paper 2 and wound, or it may be formed so as to be pressed against the paper 2 and wound at the same time as the collar 26 and the upper winding arm 24.

Now, as in the embodiment described above, the suction cup 7 of the suction member
In the present invention, a piece of paper 2 is sucked and taken out from the paper storage part 1, and is also supplied to the opening 16a of the cultivation container 16 and wrapped around and held. A paper separating mechanism A is provided that can move at least one of the suction member side and the paper storage section 1 side in a vertical direction substantially perpendicular to the stacking direction of the sheets of paper 2 while one sheet of paper 2 is suctioned by the suction member. A piece of paper 2
After the adsorption member adsorbs the paper 2, the adsorbed paper 2 is separated from the second and subsequent papers 2 by the operation of the paper separation mechanism A,
It is possible to reliably take out only the paper 2 in an adsorbed state from the paper storage part 1.

The first embodiment of the paper separation mechanism A will be described with reference to FIGS. 3 and 4. One end of a connecting rod 31 is pivotally supported on the rack 13b of the reversing mechanism 13.
The other end is pivotally supported on one side of an L-shaped link 33 that is rotatably provided around a support shaft 32, and the link 3
The other side of 3 engages with a cam 36 provided on a camshaft 35 via a roller 34, and the link 33 has an elastic mechanism 37 in which the roller 34 always elastically engages with the cam 36.
is provided. In addition, the cam 36 is arranged so that after the paper 2 is attracted to the suction cup 7, the rack 1 is released at the same time.
A protrusion 36a is formed for instantaneously moving up and down 3b. The rotation of the cam 36 causes the link 33 to swing around the support shaft 32, raising and lowering the rack 13b via the connecting rod 31, thereby rotating the pinion 13a and the reversing shaft 11, and causing the arm 6 to reversely move. It is.

Therefore, since the roller 34 is engaged with the protrusion 36a of the cam 36 as the cam 36 rotates while the paper 2 is attracted to the suction cup 7, the protrusion 36a
The link 33 swings instantaneously, and the rack 13b, pinion 13a, reversing shaft 11, and arm 6
act together to instantly move the suction cup 7 in the vertical direction almost perpendicular to the stacking direction of the sheets of paper 2, as shown in FIG. To separate. Thereafter, the paper winding operation is continued by retracting the paper storage section 1 and reversing the arm 6.

Next, a second embodiment of the paper separation mechanism A will be explained with reference to FIG. 5. One end of the rail 1a of the paper storage section 1 is pivoted by a pivot 38, and one end of a connecting rod 39 is pivoted at the other end. and the other end of the connecting rod 39,
A link 4 rotatably provided around a pivot 40
The end of the link 41 is engaged with the cam 43 via the roller 42, and the link 4
1 is provided with a spring 44 in which a roller 42 always springs into engagement with a cam 43. Further, the cam 43 has a protrusion 43a for instantaneously moving the connecting rod 39 at the same time after the paper 2 is attracted to the suction cup 7.
is formed. Then, when the paper 2 is attracted to the suction cup 7, the protrusion 43a of the cam 43 engages with the roller 42, so that the connecting rod 39 moves instantaneously and is disposed integrally with the rail 1a and the rail 1a. The paper storage section 1 is moved around the pivot 38 in the vertical direction perpendicular to the direction in which the sheets of paper 2 are piled up, and as a result, as in the first embodiment, the suctioned sheets of paper 2 are separated from the second sheet of paper 2. It is something that is separated.

In the first and second embodiments, a paper separation mechanism A using a cam mechanism is shown.
Alternatively, a solenoid may be used to provide instantaneous movement, and the mechanism may be changed as appropriate.

As described above, the present invention uses a suction member to adsorb and take out a piece of paper from a paper storage part, and also supplies it to the mouth of a cultivation container and wraps it around it to hold it. The paper separation mechanism is provided with a paper separation mechanism capable of moving at least one of the suction member side and the paper storage unit side in a vertical direction substantially perpendicular to the stacking direction of the sheets while a sheet of paper is suctioned by the suction member. Not only used paper but also new paper with overlapping vertical stripes can be reliably taken out one by one from the paper storage section, which has the effect of enabling smooth automatic paper winding.
