Description

[Detailed explanation of the invention] [Technical field of the invention] This invention is based on a fan-shaped paper made of paraffin paper, etc., placed at the mouth of the enoki mushroom cultivation container, taking into consideration moisture absorption, air permeability, and the strength of the paper itself. This invention relates to a negative pressure supply device for paper adsorption in an automatic paper wrapping device for automatically wrapping the fruiting body of enoki mushrooms according to their growth.

[Technical background of the invention and its problems] This type of reversing feeding mechanism uses a suction cup to suck paper and take it out from a paper storage unit in which paper is stacked and stored upside down, and then the paper is left in the sucked state. The container is configured to be reversely moved and supplied to the mouth of the cultivation container in a normal state.

By the way, since a negative pressure generator is connected to the above-mentioned suction member by a hose made of a flexible material,
When an unreasonable force is applied to the hose connected to the suction member during the above-mentioned reversal movement, the hose is bent and the supply of negative pressure is hindered.

[Purpose of the invention] The object of the invention is to provide a negative pressure supply mechanism for paper adsorption in an automatic paper winding device for an enoki mushroom cultivation container, which can prevent a force that would impede the supply of negative pressure from being applied to the hose during reversal movement. With the goal.

[Summary of the invention] The invention consists of a paper storage unit that stores paper in a stacked state upside down, and a negative pressure generator that is connected to a negative pressure generator by a hose, and a sheet of paper is sucked and taken out from the paper storage unit. In an automatic paper winding device for an enoki mushroom cultivation container, which is composed of a suction cup and a reversing mechanism that reverses the paper along with the suction cup using an inversion shaft as a pivot and supplies the paper to the mouth of the cultivation container in a positive state, a hose is installed in the middle of the hose. A guide body is coupled to the hose guide body, the hose guide body is rotatably pivoted to the reversing shaft, and the hose guide body is provided so as to be able to respond to the reversing movement of the reversing mechanism, and the negative pressure is generated. One end of the hose is connected to the device, and the other end of the hose is freely rotatably connected to the hose guide body.

[Embodiment of the invention] First, an embodiment of an automatic paper winding 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 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 the 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 fan shape of the paper 2. The stacked papers 2 are sandwiched and held between the push plate 4 and a pair of stoppers 5 provided on both side walls of 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 arranged to face the paper 2 stored in the paper storage section 1, and a suction cup 7 is provided at the tip of each arm 6 so as to be able to swing laterally by a support shaft 8. It is pivoted and its suction cup 7
is applied with an elastic force by the projectile 9 so as to swing inward at all times, and is held by a stopper (not shown) in an inwardly inclined state at approximately 45 degrees. Further, an abutting piece 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 10a of the piece 10 is bent outward. Further, a negative pressure generating device P 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 control mechanism (not shown). In that case, in the drawing, a rack 13b is disposed to mesh with a pinion 13a provided on the reversing shaft 11, and the arm 6 is reversed by the lifting and lowering movement of the rack 13b, but the pinion rack is not shown without using a pinion rack. A rotary 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 holder that follows the shape of the opening 16a of the paper holder, and is arranged to be movable forward and backward by a control mechanism. Although not shown, the negative pressure generating device P 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 holding member that can hold the object 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 arm 21 for lower winding is pivotally attached to one of the operating rods 19 via a link 20 so as to be able to freely swing around a support shaft 22. A force directed toward the cultivation container 16 is constantly applied to each arm 21 by a spring 23. Further, an upper winding arm 24 is connected to the other operating rod 19 via a spring 23 to support 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 clip 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 is moved in conjunction with the upper winding arm 24.
A clip storage section 29 is disposed above the upper winding arm 24 so as to prevent the clip 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 by a support shaft, and this paper receiving member 30 Part 3
A force directed toward the cultivation container 16 is always applied to the container 0 by a spring (not shown).

Therefore, when the paper storage section 1 moves forward by an appropriate control mechanism, the tip end 10a of the contact piece 10 first contacts the outermost paper 2 among the multiple stacked sheets of paper 2, and the paper storage section 1 moves forward. 1 advances, the contact piece 10
As the tip 10a slides against the paper 2 and moves outward, the suction cup 7 integrated with the contact piece 10 swings outward, that is, toward the paper surface, against the elastic force of the bullet 9, and the suction cup 7 is in a nearly horizontal state parallel to the paper surface and attracts 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 inward swing state of approximately 45 degrees due to the elastic force of the bullet 9, so that the paper 2 attracted to the suction cup 7 has an approximately U-shaped curved shape. formatted into. In this case, the suction cup 7 is held swinging at approximately 45 degrees, but the suction cup 7 may 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, although the paper storage section 1 side is formed to be movable forward and backward when sucking the paper 2, the suction cup 7 and the arm 6 side may be made movable forward and backward to suction the paper 2.

In this way, after a sheet of paper 2 is taken out from the paper storage section 1, the arm 6 is turned by approximately 180 degrees by the operation of the reversing mechanism 13, so that the upside-down paper 2 is turned right-side up, and the paper 2 is supplied to the mouth 16a of the cultivation container 16 that has already been supplied to the specified location 15 manually or by an appropriate supply mechanism (not shown). The curved portion of the paper 2 is arranged so as to correspond to the mouth 16a. Next, when the paper presser 14 is moved forward by the control mechanism, the curved portion of the paper 2 is inserted into the cultivation container 16.
The paper 2 is pressed against the peripheral surface of the opening 16a of the cultivation container 16 and held in a substantially U-shape along the outer peripheral surface of the opening 16a of the cultivation container 16.

After that, the paper 2 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. The tip of the curved lower winding arm 21 contacts the paper 2, and then the force of the spring 23 and the link 20
, one side of the paper 2 is pressed against the opening 16a of the paper 16 for cultivation, and is gradually wound so as to smooth out any wrinkles or looseness, and then the upper side rotating shaft 18
rotates, the operating rod 19 and the upper winding arm 24 move the other side of the paper 2 toward the cultivation container 16, the end of the clip 26 comes into contact with it, and then the force of the spring 25 moves the other side of the paper 2 toward the cultivation container 16. The clip 26 is wrapped along the opening 16a of the paper 2 so as to smooth out the wrinkles so that both ends of the paper 2 are stacked vertically, and at the same time as the winding is completed, the clip 26 separates from the groove 27 and automatically fits into the opening 16a. Wrap and secure paper 2.
In this case, the paper receiving member 30 supports the lower end of the paper 2 in conjunction with the lower winding arm 21 and the upper winding arm 24.

Thereafter, the upper winding arm 24 and the lower winding arm 21 are returned to their original positions, and the cultivation container 16 with the paper 2 wrapped around it is transported out manually or by an appropriate transport mechanism. In that case, the lower arm 21 returns along the circumferential surface 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 ends of the paper 2 and fixing it with the clip 26, and in the above explanation, the clip 26 is
Although the upper winding arm 24 is formed so as to be pressed directly against the paper 2 and wrapped, it may be formed so that the upper winding arm 24 is directly pressed against the paper 2 and wound, or the clip 26 and the upper winding arm 24 are simultaneously pressed against the paper 2 and wound. You can stay like that. In addition, when wrapping the paper, the paper may be wrapped by the lower winding arm and the upper winding arm, and then the clips may be fitted into the mouth of the cultivation container by operating the individually arranged clip storage sections. Alternatively, instead of using clips, by providing fasteners, etc. on both ends of the paper in advance, when the paper is wound around the mouth of the cultivation container, the fasteners, etc. will overlap the two ends of the paper and fix it. Good too.

Now, as shown in the above-mentioned example, after a sheet of paper 2 is sucked and taken out from the paper storage section 1 that stores the paper 2 upside down by a pair of suction cups 7, the sheet of paper 2 is left in the sucked state on the inversion axis. 11, the negative pressure supply mechanism A for paper adsorption is configured as shown in FIGS. 3 and 4.
