In any one of the above-described embodiments, a vacuum suction plate is provided on the bottom receiving plate to be attached to a bag mounted on the receiving table.

[0011]

According to the first aspect of the present invention, the bag placed on the receiving table is held by being suctioned by the suction means. When the elevating drive means is operated with the upper end of the bag opened, the pedestal is lifted upward and inverted, and the raw material is discharged from the bag.

According to the second aspect of the present invention, when the bag is placed on the receiving table, the bottom receiving plate rotates the vacuum suction plate to a position where the vacuum suction plate comes into contact with the bag, and the bag can be securely held by the vacuum suction plate. According to the configuration of the third aspect, when the bag is placed on the receiving table, the bottom receiving plate is rotated in a direction in which the interval between the pair of vacuum suction disks is reduced, and the bag can be securely held by the vacuum suction disk.

According to the fourth aspect of the present invention, when the bag is placed on the receiving table, the bottom receiving plate rotates the vacuum suction plate to a position where the vacuum suction plate comes into contact with the bag, and the bag can be securely held by the vacuum suction plate. Furthermore, when the cradle is raised and inverted to lighten the bag, the bottom receiving plate returns to the biasing position, and the vacuum suction plate expands while the bag is being vacuum-sucked, thereby discharging the entire amount of the bag material. Can be expected.

According to the fifth aspect of the present invention, the bag is vacuum-sucked from the bottom and the side.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a raw material charging apparatus according to the present invention will be described with reference to FIGS. 2 is attached to the receiving table 5 attached to the vertical conveyor 3 as a lifting drive means.

On the bottom of the receiving table 5, a bottom receiving plate 6 slidably supported in a vertical direction, a first vacuum suction plate 8a rotatably supported by a shaft 7a, and a rotation by a shaft 7b. A second vacuum suction disk 8b movably pivotally supported is provided.

The first and second vacuum suction disks 8a and 8b
The L-shaped levers 9a, 9b are attached to the upper ends of the L-shaped levers 9a, 9b.
It is mounted on the cradle 5 by being pivoted at b.

The bottom receiving plate 6 is urged upward by a coil spring 10, and an adjusting screw 11 extending toward the rear surface of the bottom receiving plate 6 is attached to the lower ends of the L-shaped levers 9a and 9b. .

The first and second vacuum suction disks 8a, 8b
And the bottom receiving plate 6 is connected to a vacuum pump 13 via a hose 12.
It is connected to the. Until the bag 1 of raw material is placed on the receiving table 5, the bottom receiving plate 6 is urged upward by the coil spring 10,
The space between the first and second vacuum suction disks 8a and 8b is widened.

At the time of charging the raw material, when the worker places the bag 1 on the receiving table 5, the bottom of the bag 1 is vacuum-sucked to the bottom receiving plate 6, and as shown in FIG. 6 lowers against the urging of the coil spring 10, and the L-shaped levers 9a, 9b rotate inward about the shafts 7a, 7b via the adjusting screw 11 to rotate the first and second vacuums. The distance between the suction disks 8a and 8b is reduced, and the first and second vacuum suction disks 8
a, 8b are pressed, and the bag 1 is vacuum-sucked.

A staff member cuts open the upper portion of the bag 1 held by vacuum suction between the first and second vacuum suction disks 8a and 8b and the bottom receiving plate 6, and turns the opening portion of the bag 1 outward to return to the receiving stand. 5
Is held down by the clamps 14a and 14b provided on the upper part of the frame.

When the vertical conveyor 3 is operated after being set as described above, the receiving stand 5 is raised and inverted as shown by the phantom line in FIG.
At this time, the load applied to the bottom receiving plate 6 is reduced by the reversing of the receiving table 5, and the bottom receiving plate 6 pushes the bottom of the bag 1 to the inside of the bag 1 by the urging force of the coil spring 10. At the same time, the distance between the first and second vacuum suction disks 8a and 8b is increased, and the bag 1 is spread on both sides, so that the entire amount of the raw material of the bag 1 can be discharged.

In this way, since the bag 1 can be set on the receiving table 5 and the raw material can be supplied from the bag 1 to the supply device 4, it is not necessary to transfer the bag 1 to the bucket as in the prior art, and the workability is improved. Significant labor savings.

In the above embodiment, the first and second vacuum suction disks 8a and 8b vacuum-suck from both sides with the bag 1 at the center. However, the vacuum suction disk 8a or the vacuum suction disk 8 from one side of the bag 1 is used.
It is also possible to adopt a configuration in which vacuum suction is performed only with b.

[0025]

As described above, according to the present invention, the receiving table on which the bag containing the raw material is placed, the elevating drive means for lifting the receiving table upward and inverting it, and vacuum-sucking the bag mounted on the receiving table. Since the suction means is provided, the bag placed on the receiving table is held by being vacuum-sucked by the suction means, and when the upper end of the bag is opened to operate the lifting / lowering driving means, the receiving table is lifted upward and inverted, and the bag is turned over. The raw material is discharged from the container, and it is not necessary to transfer the material from the bag to the bucket as in the related art, and the workability can be greatly reduced.

Further, by providing a bottom receiving plate which is pushed by the bag mounted on the receiving table and rotates the vacuum suction disk to a position where it contacts the bag mounted on the receiving table, the vacuum suction disk can be used. The bag can be reliably held.

Further, the bottom receiving plate was urged upward, and the weight of the bag placed on the receiving stand lowered the bottom receiving plate against the urging, and the vacuum suction plate was placed on the receiving stand. By configuring to rotate to the position where it contacts the bag, the load acting on the bottom receiving plate is reduced by inverting the receiving stand, and the bottom receiving plate biases the bottom of the bag inside the bag by the biasing force. And the vacuum suction cup expands the bag, so that all the raw material can be discharged from the bag.
