Description

[Detailed explanation of the invention] [Purpose of the invention] (Industrial application field) The invention consists of supplying bags, opening the bags, packing similar materials such as mushrooms, deaerating the inside of the bags, and sealing the opening of the bags. Regarding packaging devices for mushrooms and other similar products that perform a series of operations,
In particular, the present invention relates to an improvement in a clamping structure for suspending the bag horizontally by clamping the side end portion of the bag supplied to a predetermined location by a bag supply suction member with a clamping member.

(Prior Art) Generally, in this type of packaging device, as shown in FIGS. 6 to 10, a large number of bags 1 made of a flexible material such as polyethylene are stored horizontally in a stacked state in a storage container 2. At the same time, the storage container 2 is connected to an air cylinder 3 and is configured to be movable up and down by the operation of the air cylinder 3. Above the storage container 2, a suction member 4 for supplying bags is connected to an air cylinder 5.
The bag is rotated by 90 degrees about the shaft support 6 as a rotation fulcrum by the operation of , and the bag 1 sucked by the suction member 4 can be supplied to a predetermined location. Furthermore, a fixed clamping member 7 is attached to the main body frame 8 at the location where the bag 1 is supplied.
At the same time, a movable clamping member 9 facing the fixed clamping member 7 moves horizontally by the operation of an air cylinder 10 to clamp the side end of the bag 1 between it and the fixed clamping member 7 and suspend it. It is set up so that it can be lowered. Furthermore, a pair of suction members 11, 11 for opening the bag are disposed facing each other on both sides of the opening side of the bag 1, which is suspended horizontally by the fixed clamping member 7 and the movable clamping member 9. , 11 are formed so as to be reciprocated in the horizontal direction by the operation of air cylinders 12, 12 to open the bag mouth.

Then, as shown in FIG. 6, when the storage container 2 rises due to the operation of the air cylinder 3 and reaches the position of the suction member 4, one of the bags 1 stacked inside the storage container 2 is suctioned by the suction member 4. and then storage container 2
descends. Next, by the operation of the air cylinder 5, the suction member 4 which has suctioned the bag 1 is rotated by 90 degrees about the shaft support 6 to supply the bag 1 to a predetermined location. Furthermore, as shown in FIG. 7, the movable clamping member 9 moves toward the fixed clamping member 7 by the operation of the air cylinder 10, and the upper end of the bag 1 is clamped and suspended between the clamping members 7 and 9. Thereafter, the negative pressure of the suction member 4 is switched to the suction members 11, 11 by a switching valve (not shown), and the suction member 4 returns to rotation. Furthermore, by the operation of the air cylinders 12, 12, the pair of suction members 11, 11 move to both sides of the bag 1, suck the bag opening, and then move outward to open the bag opening as shown in FIG. Thereafter, a series of mushrooms and similar materials (not shown) are placed in the bag 1, the bag opening is sealed, and the bag is taken out.

Conventionally, as shown in FIG. 9, a flat bag pressing member 1 made of rubber, sponge, etc. is provided on each clamping surface of the movable clamping member 9 and the fixed clamping member 7.
3 and 13 are fixed by fixing means such as double-sided tape, and the bag 1 is clamped and suspended by the clamping members 7 and 9 through the elasticity of the pressing members 13 and 13.

(Problem to be solved by the invention) In the above-mentioned conventional technology, the bag pressing members 13, 13 made of rubber, sponge, etc. are fixed to the gripping surface of the bag holding member 10, and the bag pressing members 13, 13 are Since the bag 1 is clamped through elasticity, for example, the bag pressing members 13, 13
The clamping force may be weakened due to fatigue of the bag pressing member 13 or enoki mushroom residue adhering to the bag pressing member 13. In such a case, the suction member 11,
11 attracts the bag opening and opens it, the tensile force causes the bag opening side of the bag 1 to come off from between the clamping members 7 and 9 as shown in FIG. There was a problem in that it was difficult to accommodate the bag 1 into the bag 1.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a packaging device for mushrooms and similar products that can prevent the bag opening side of the bag from coming off the pair of clamping members.

[Structure of the idea]

(Means for Solving the Problems) The present invention uses a suction member for bag feeding to suck a bag horizontally and feed it to a predetermined location, and the upper end of the bag is held by a pair of holding members and suspended. , in a packaging device for mushrooms and other similar products that opens a bag opening using a suction member for opening the bag, stores mushrooms and other similar products in the bag opening, and then seals the bag opening, in the longitudinal direction of the inner clamping surface of the clamping member; A groove-shaped attachment part is formed in the groove-shaped attachment part, and an elastic bag pressing member is provided in the groove-shaped attachment part, and a clamping pressure adjustment screw is screwed into the bag opening side of the clamping member from the outside, and the clamping pressure adjustment screw is used to tighten the bag. Then, the bag opening side of the bag pressing member is pushed out, so that the amount of protrusion of the bag pressing member from the bag opening side clamping surface can be made larger than other parts.

(Function) With the above structure, even if the clamping force of the bag pressing member becomes weak due to fatigue of the bag pressing member or adhesion of enoki mushroom residue, etc., and the bag opening side of the bag is likely to come off when the bag opening is opened, the bag can be clamped easily. By screwing in the pressure adjustment screw, the protruding amount of the bag pressing member on the bag opening side is made larger than the other parts, thereby increasing the clamping force on the bag opening side.
