Relating to a stopping device.

[Conventional technology]

A conventional device of this type was proposed in Japanese Patent Publication No. 55-42801, which was configured so that after the start switch was turned on manually, a series of paper roll operations and a cultivation container supply operation were continued. There is. However, since this device continuously performs a series of paper rolling operations, there is a problem in that it continues to operate even if the cultivation container falls over.

[Problem that the invention attempts to solve]

In the above-mentioned conventional technology, when the cultivation container falls over before it is supplied to a predetermined location where paper rolling is performed, the operation mechanism is not properly operated because the overturned cultivation container is forcibly pressurized to operate continuously. There was a problem that it was easy to break down due to overload.

Therefore, an object of the present invention is to provide an emergency stop device for an automatic paper rolling device for an enoki mushroom cultivation container, which can make an emergency stop in the event of an abnormality such as when the cultivation container falls over.

[Means for solving problems]

[Effect]

In this invention, during normal operation, the emergency stop switch is maintained in a non-operating state by the reciprocating rotation of the movable piece due to the normal rotation of the main shaft, and when the cultivation container falls over, an instantaneous reverse force is applied to the main shaft. When this occurs, the emergency stop switch is activated due to the engagement between the gear and the roller, and the operating mechanism is brought to an emergency stop.

〔Example〕

First, an embodiment of an automatic paper rolling device for an enoki mushroom cultivation container will be described with reference to FIGS. 5 and 6.

Reference numeral 1 denotes a paper storage section in which a large number of fan-shaped papers 2 are stacked and stored upside down, and is provided so as to be movable forward and backward by an actuation mechanism A such as a cam control mechanism. Further, in the paper storage section 1, there is a push plate 4 which can shape the central part 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.
is arranged, and the stacked papers 2 are sandwiched and held between this press plate 4 and a presser member 5 provided in the paper storage section 1. In addition, 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 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 an actuation mechanism A such as a cam control mechanism. 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 vertically installed 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 an operating mechanism A such as a cam control mechanism. Each operating rod 1
9 is constructed, and an elastic, curved lower winding arm 21 is pivoted 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 lower arm 21
A force always directed toward the cultivation container 16 is applied to each by a spring 23. Further, the upper winding arm 24 is attached to the other operating rod 19 with a spring 2.
The upper winding arm 24 is pivotally connected to a support shaft 22a via a support shaft 22a, and a recessed groove 27 is formed in the upper winding arm 24 to accommodate a substantially C-shaped clip 26 made of an elastic material such as plastic. This upper winding arm 2
In the standby state of 4, 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 moves in conjunction with the upper winding arm 24 to prevent the clip 26 from falling under its own weight. A clip storage section 29 is disposed above the upper winding arm 24 so as to prevent this. 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. cultivation container 16
It is given the power to move towards the side.

Therefore, when the paper storage unit 1 is moved forward by the actuation mechanism A such as a cam control mechanism, the tip end 10a of the actuation pin 10 first contacts the outermost paper 2 among the multiple stacked sheets of paper 2, and As the paper storage unit 1 moves forward, the actuating pin 10 moves outward, so the suction cup 7 integrated with the actuation pin 10 rotates outward, that is, toward the paper surface, against the elastic force of the spring 9. is in a substantially 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 actuation mechanism A such as a cam 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. As the paper storage section 1 moves backward, the suction cup 7 moves inward approximately 45 degrees due to the elastic force of the spring 9.
In order to return to the normal swinging state, the paper 2 sucked by the suction cup 7 is shaped into a substantially 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. 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, 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 an actuation mechanism A such as a cam control mechanism, the curved portion 2a of the paper 2 is pressed against the circumferential surface of the opening 16a of the cultivation container 16. The opening 16 of the cultivation container 16
Paper 2 is held in a substantially U-shape along the outer peripheral surface of a. In addition, in the above explanation, the paper storage section 1 stores the paper 2 in the normal state, with the arm 6 of the suction cup 7 reversed to supply the paper 2 to the opening 16a of the cultivation container 16.
The arm 6 of the suction cup 7 is arranged to move forward and backward, and the sheet of paper 2 is shaped into a curved shape by the forward and backward movement of the arm 6, and then the arm 6 is moved forward without reversing to open the opening of the cultivation container 16. The paper 2 may be supplied to the section 16a, or the paper 2 may be supplied flat without being shaped into a curved shape, and the configuration for supplying the paper 2 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 operating mechanism A, and the operating rod 19, the link 20, and the lower arm 21 are moved to the cultivation container 16 side. The tip of the moving and 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 end of the clip 26 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 the wrinkles, so that both ends of the paper 2 are overlapped vertically, and when the winding is completed, At the same time, the clip 26 separates 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. Note that the above is just an example of a mechanism for winding both sides of the paper 2 and fixing it with the clips 26.
Although the upper winding arm 24 is formed so as to press directly against the paper 2 and wind it, the upper winding arm 24 may be formed so as to directly press against the paper 2 and wind it, or the above-mentioned clip 26 and the upper winding arm 24 may be pressed against the paper 2 at the same time. They may be wound in contact with each other. In the case of winding the paper, the paper may be wound by the upper winding arm and then the clips may be fitted into the mouth of the cultivation container by operating the individually disposed clip storage section. Alternatively, instead of using clips, fasteners or the like may be provided on both ends of the paper so that when the paper is wound around the mouth of the cultivation container, the two ends of the paper are overlapped and fixed by the fasteners or the like. . Furthermore, the actuation mechanism A is, for example, proposed by the same applicant in JP-A-60
-70009 publication may be used.

Next, a description will be given of the start switch and the cultivation container transfer mechanism B that performs one cycle of paper rolling operations when the cultivation container is brought in.

In such normal operation, if the cultivation container 16 falls over at the relay point 15b as shown in FIG.
Even if an attempt is made to move the transfer member 39, the overturned cultivation container 16 collides with the guide member 35, the retaining member 17, etc., resulting in a locked state, and a reversing force is instantaneously applied to the camshaft 52. Then, when the camshaft 52 and the sprocket 55 reverse, the roller 58 is pushed upward by the teeth 55a of the sprocket 55, and the movable piece 57 attempts to rotate clockwise about the shaft 57a as a fulcrum, but there is no room for rotation. Therefore, switch D is activated by pushing the actuating piece 56 of switch D. As a result, the motor 54 is brought to an emergency stop by the brake.

In this way, in the above embodiment, when an overload condition occurs during a series of paper rolling operations and a reversing force is instantaneously applied to the camshaft 52, the switch D is activated by the engagement between the roller 58 and the sprocket 55. Since the motor 54 comes to an emergency stop, no strain is applied to the actuating mechanism A in an abnormal condition, and damage can be prevented.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the gist of the present invention. For example, it goes without saying that the paper winding device can be applied to various types. Further, a roller biasing spring may be provided as necessary.
