And a scraper 6 for sending out a later empty bag to the outside, and each of the scrapers 4, 5, 6 can be opened and closed as it moves forward and backward.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIGS. 1, 2 and 3 show the entirety of the powder bag transfer device of the present invention. The transfer device 1 is provided with support plates 3 at lower portions on both sides in the longitudinal direction of a flat rectangular frame 2, and Between the support plate 3, three scrapers 4, 5 and 6 are provided so as to be openable and closable, and the entire transfer device 1 is combined with a rack 7 and a pinion 8 in the transfer direction of the powder bag A (from the right in FIGS. 2 and 3). (Left direction).
[0009]
The horizontally long scrapers 4, 5 and 6 are bent at right angles at both ends to form connecting plates 4a, 5a and 6a. Each connecting plate 4a, 5a and 6a is rotatable on the supporting plate 3. The shaft is connected. The scraper 4 is located on the rightmost side in the drawing.
The scraper 5 is located substantially at the center in the length direction of the support plate 3. Further, the scraper 6 is located on the leftmost side on the side opposite to the scraper 4.
[0010]
Each of the scrapers 4, 5, 6 rotates between a vertically closed state and a horizontally open state by operating a cylinder 9 attached to each of the connecting plates 4a, 5a and 6a. . That is, the base of each cylinder 9 is fixed to the support plate 3 in a horizontal state. The upper ends of the connecting plates 4a and 5a of the scrapers 4 and 5 and the tip of the rod of the cylinder 9 are rotatably connected. When the rod is pulled, the one-dot chain line from the vertical closed state shown by the solid line in FIG. To the horizontal open state shown in FIG.
[0011]
The scraper 6 rotatably connects the tip of the rod of the cylinder 9 and the lower part of the connecting plate 6a, and turns from a vertically closed state to a horizontally open state by extending the rod. Therefore, the scrapers 4 and 5 and the scraper 6 open and close in the opposite directions. The height position when each of the scrapers 4, 5, and 6 is opened horizontally is a height at which the powder bag A can pass in a horizontal state.
[0012]
As described above, the entire transfer apparatus 1 can be reciprocated by the combination of the rack 7 and the pinion 8. The racks 7 integrally provided in parallel with the frame body 3 on both sides in the longitudinal direction of the frame body 3 are mounted on a plurality of rotating rollers 11 projecting inward from an external frame 10 surrounding both sides of the transfer device 1.
[0013]
A pair of pinions 8 meshing with the racks 7 on both sides are fixed to both ends of one rotating shaft 12, and the rotating shaft 12 is driven to rotate by a motor 13 that can rotate in the reverse direction. Therefore, the rack 7 slides on the rotating roller 11 by the rotation drive of the pinion 8, so that the transfer device 1 reciprocates along the transfer direction of the powder bag A. Since one end of the rotating shaft 12 is connected to the outer frame 10 via a bearing (not shown) and the motor 13 is fixed to the outer frame 10, the meshing state between the rack 7 and the pinion 8 does not come off.
[0014]
The entire transfer apparatus 1 described above is normally stopped facing a bag opening mechanism and a raw material discharge mechanism which are installed close to each other along the transfer direction of the powder bag A, as shown in FIGS. The bag opening mechanism, the raw material discharging mechanism, and the like can use a device generally used conventionally.
[0015]
Next, the intermittent continuous transfer of the powder bag A by the transfer device 1 will be described with reference to FIGS.
The transfer device 1 having the above-described configuration is located above the bag opening mechanism and the raw material discharging mechanism as described above. As shown in (a), when the powder bag A is placed at the mounting position, the pinion 8 is driven to rotate by the motor 13, the rack 7 is run, and the transfer device 1 is passed between the outer frames 10 to place the powder bag A. Move to position.
[0016]
The powder bags A may be placed on the placement position by the Pare robot in order from the powder bags A stacked on the pallet, or may be carried to the placement position using a belt conveyor, a roller conveyor, or the like. .
[0017]
At the time of moving to the placement position, at least the scraper 4 is open upward, so that the powder bag A at the placement position is accommodated in the transfer device 1 as shown in (b). Next, when the scraper 4 is closed and the transfer device 1 is pulled back to the original position, the powder bag A is moved to a position above the bag opening mechanism by the scraper 4 and stopped as shown in FIG. The stop of the transfer device 1 at the forward position, the stop at the retreat position, and the like may be performed by stopping the motor 13 by detecting a sensor, and these operations are automatically managed by a computer similarly to other operations.
[0018]
Since the next powder bag A is placed at the standby position as shown in (d), if the transfer device 1 advances by opening the scrapers 4 and 5, the first powder bag A1 as shown in (e). And the next powder bag A2 enter the transfer device 1. In this state, if the scrapers 4 and 5 are closed and the transfer device 1 is returned to the original position, the powder bag A1 enters the raw material discharge mechanism and the powder bag A2 is placed on the bag opening mechanism as shown in FIG. Will be located.
[0019]
Usually, the raw material discharging mechanism is hermetically sealed by a housing structure so as not to be scattered to the outside when discharging the powder or minute particles from the powder bag A. The inlet side of A and the outlet side of the empty bag after discharging the raw material can be opened and closed by a shutter.
[0020]
The raw material is discharged from the first powder bag A1 that has been opened, and the bag opening operation is simultaneously performed on the powder bag A2. At this stage, since the next powder bag A3 has been sent to the mounting position as shown in (g), if the transfer device 1 is advanced with all the scrapers 4, 5, and 6 opened, ( As shown in (h), the powder bag A2 and the powder bag A3 are located in the transfer device 1, and the first powder bag A1 (empty bag) is left in the raw material discharge mechanism.
[0021]
In this state, if all the scrapers 4, 5, and 6 are closed and the transfer device 1 is returned to the original position, the empty bags (powder bags A1) after the discharge of the raw materials are sent out by the scrapers 6. At this time, if the exit shutter of the raw material discharging mechanism is opened, the empty bag is discarded outside.
[0022]
Then, the powder bag A2 is located in the raw material discharge mechanism, and the powder bag A3 is located on the bag opening mechanism, and the respective processes are performed simultaneously.
Since the new powder bag A4 is at the placement position, if all the scrapers 4, 5, and 6 are opened and advanced, the same state as the above (h) will be obtained. Thereafter, the same operation is repeated. The opening of the powder bag A, the discharge of the raw material, and the disposal of the empty bag are intermittently and continuously performed.
[0023]
That is, the scraper 4 has a function of sending the powder bag A at the mounting position to the bag opening mechanism, and the scraper 5 has a function of sending the opened powder bag A to the raw material discharging mechanism. Further, the scraper 6 has a function of sending an empty bag from which the raw material has been discharged to the outside from the raw material discharging mechanism.
[0024]
【The invention's effect】
According to the present invention described above, the transfer device 1 sends the powder bag A at the placement position to the bag opening mechanism by the openable and closable scrapers 4 and 5, and discharges the powder bag A after the bag opening to the raw material discharge. Since the scraper 6 can discharge the empty bag after discharging the raw material to the outside, it can automatically process the feeding of two powder bags A and the sending of one empty bag at the same time. It is. Accordingly, operations such as opening, discharging, and abandonment of the powder bag A can be continuously performed mechanically, and the processing efficiency can be improved.
[0025]
In addition, since the powder bags A are placed at the determined positions of the bag opening mechanism and the raw material discharging mechanism by the transfer device 1, the determined positions of all the powder bags A are formed by, for example, a cutter knife to form a bag opening line. In the raw material discharge mechanism, the raw material can be discharged from the powder bag A at a predetermined position, and all the raw materials can be put into the hopper without waste.
