Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a soft bag for automatic filling, which is capable of effectively attaching and detaching a soft bag for automatically filling powdery particles or the like to a holder for supporting the bag.

[0002]

2. Description of the Related Art Conventionally, as seen in Japanese Utility Model Publication No. 58-33051 and Japanese Utility Model Publication No. 59-33767, a flange frame is provided at the opening of a softening bag for automatic filling, and the flange frame is mounted on a holder. It is known that the bag can be placed in a box and packed, and the bag can be closed by the holder.

[0003]

However, in practice, such a flange frame is constructed so that, for example, it can be assembled by baking rubber on an iron plate or can be closed by a holder. However, there is a problem that the structure becomes complicated and the cost increases, and the cost becomes high and the profit cannot be obtained.

[0004]

The present invention has been devised so as to solve such problems and to be suitably implemented with a simple structure at a low price. Therefore, the invention is attached to the opening peripheral edge portion of the softening bag. A ring-shaped step on which an annular wire can be placed is formed on the outer periphery of the upper side of the opening of the holder so that the wire can be deformed by an external force, and the wire can be attached to the opening of the holder from below. It can be deformed by an external force so that it can be inserted, multiple grooves are formed on the upper surface of the holder that are open to the outer peripheral side of the step and extend in the radial direction, and wires are inserted in each groove toward the center of the opening. It is configured to be equipped with each pressing frame that can be pressed in and out freely.

[0005]

Therefore, when the wire is deformed and inserted into the opening of the holder from below and the annular wire is placed on the annular step of the holder, the softening bag can be attached to the holder. After the powder bag or the like is automatically filled in the softening bag suspended by the holder, each pressing frame is moved inward along each groove, and the pressing wire deforms the annular wire, It will be possible to remove downward through the opening in the holder.

[0006]

Example A shows a long softening bag which can be filled with powder or the like, and the entire circumference of the opening of the softening bag A is bent outward and sewn 6 to form an annular bag portion a. The annular bag portion a is internally provided with an annular wire 1. The wire 1 and the annular bag portion a are made deformable by an external force, and the wire 1 is formed in a ring in advance. The wire 1 is inserted into the annular bag portion a, or the straight wire 1 is bent into an annular shape and inserted into the annular bag portion a.

Reference numeral B denotes a plate holder, which is conveyed by a conveyor as shown by arrows a, b, and c as shown in FIG. 8 and is attached with the softening bag A at the lower right position in the figure. , The softening bag A is automatically filled with powder particles and the like at the lower left side of the drawing while being conveyed in the two directions of the arrow, and the circular opening 3 is provided at the center of each holder B.
And the wire 1 is formed on the outer periphery on the upper side of the opening 3.
An annular step portion 2 is formed on which an annular bag portion a in which is loaded can be placed, and on the upper surface of the holder B, four grooves 4a and 4b which are open to the outer peripheral side of the step portion 2 and extend in the radial direction, respectively. , 4c,
4d is formed in a cross shape, and each of the grooves 4a to 4d is equipped with a cylinder type pressing frame 5 capable of pressing the wire 1 toward the center side of the opening 3 so that the pressing frame 5 can be retracted. Each pressing frame 5 can move up and down at the same time, and when the holder B is conveyed to the filling position, it is moved down to the outer side position of each groove to operate.

Therefore, when the holder B is conveyed to the lower right position in FIG. 8, the operator deforms the wire 1 and the annular bag portion a into an elliptical shape as shown in FIG. Insert from below into the opening 3 of
After that, the softened bag A can be attached to the holder B by placing the wire 1 and the annular bag portion a, which are restored to the annular shape and are horizontal, on the annular step portion 2.

When the holder B having the softening bag A attached thereto is conveyed in the two directions of the arrows and the softening bag A is filled with the powdery particles or the like at the filling position, each pressing frame 5 is placed outside each groove. 10, the pressing frame 5 projecting into the groove 4b bends and deforms the wire 1 as shown in FIG. 10, and then projects into the grooves 4a and 4c as shown in FIG. The pressing frames 5 and 5 bend the wire 1 to further deform it, and as shown in FIG. 12, the pressing frame 5 protrudes into the groove 4d.
Causes the wire 1 to bend and the wire 1 and the annular bag portion a to be deformed into a smaller size than the opening portion 3, so that the opening portion of the softening bag A can be removed downward through the opening portion 3 of the holder B. After that, the opening of the softening bag A can be closed with a string.

If the operation sequence of each pressing frame 5 is changed,
As shown in FIGS. 13 and 14, the annular bag portion a and the wire 1
Can be variously deformed to be smaller than the opening 3.

[0011]

As described above, according to the present invention, the wire 1 attached to the peripheral edge of the opening of the softening bag A is deformed and inserted into the opening 3 of the holder B from below, and the wire 1 that is restored to the annular shape is held. When placed on the annular step portion 2 of B, the holder B
The soft bag A can be easily attached to the
When the softening bag A is automatically filled and then the pressing frames 5 are moved inward along the grooves 4a to 4d, the wire 1 is deformed to pass through the opening 3 of the holder B and is effective downward. Therefore, the softening bag A can be effectively attached to and removed from the holder B with good workability, and the cost can be reduced with a simple structure. .
