That is, a series of operations including conveyance of the bag opening machine 10 by the crane 20, opening and closing of the lid of the storage tank 90 by the lid opening and closing machine 81, discharge of the granular material by the bag opening machine 10 and the like are automatically performed by the control device 30. Preferably, it is done.

[Usage method of bag opening and conveying device and bag opening and conveying method]
Hereinafter, the usage method of the bag opening and conveying apparatus 1 and the bag opening and conveying method by the bag opening and conveying apparatus 1 will be specifically described.

  First, the flexible container bag 80 is attached to the bag opening machine 10. More specifically, for example, as shown in FIG. 6, the lifting tool 82 on which the hanging strap 81 of the flexible container bag 80 is hung is lifted by a forklift 99 or the like and placed on the horizontal rail 111 of the inner frame 11. Then, the inner frame 11 and the hanging tool 82 are fixed.

  Subsequently, the work window 151 is opened to connect the opening of the flexible container bag 80 and the chute 13. FIGS. 7 to 9 are views showing the vicinity of the chute 13 extracted from the configuration of the bag opening machine 10, and are diagrams for explaining a method of attaching the flexible container bag 80 to the bag opening machine 10.

  The flexible container bag 80 used in the present embodiment has a double structure of an outer bag (not shown) and an inner bag 83, and discharges granular materials to the lower part of the outer bag and the inner bag 83, respectively. Are provided. FIG. 7 illustrates a state in which the outer bag is peeled and the inner bag 83 is exposed. The opening of the inner bag 83 is closed by the inner bag string 84.

  First, as shown in FIG. 7, the lower end of the inner bag 83 and the upper end of the chute 13 are connected in a state where the opening of the inner bag 83 is closed by the inner bag string 84. More specifically, the lower end of the inner bag 83 is put on the upper end of the chute 13 and fastened by an annular clamp 131 or the like. It is preferable that the inner bag 83 and the chute 13 are closely connected so that the granular material does not leak from the gap between the inner bag 83 and the chute 13 when the inner bag string 84 is unwound.

  Subsequently, as shown in FIG. 8, the opening / closing machine 14 is operated and the portion between the inner bag cord 84 and the chute 13 of the inner bag 83 is clamped from both sides.

  Subsequently, as shown in FIG. 9, the inner bag string 84 is unwound while the inner bag 83 is tightened by the opening / closing device 14. Even when the inner bag string 84 is unwound, since the opening / closing machine 14 is closed, the powder and granular materials filled in the flexible container bag 80 are not discharged. That is, the granular material filled in the flexible container bag 80 is in a state in which the discharge is regulated by the opening / closing machine 14.

  In this example, the opening / closing machine 14 is disposed above the chute 13 and regulates the discharge of the granular material by tightening the flexible container bag 80 from the outside. However, the opening / closing machine 14 only needs to be able to regulate the discharge of the granular material from the chute 13. The opening / closing machine 14 may be, for example, a valve provided in the middle of the chute 13 or on the discharge side.

  However, it is more preferable that the opening / closing machine 14 is disposed above the chute 13 as in the present embodiment and regulates the discharge of the granular material by tightening the flexible container bag 80 from the outside. According to this structure, the opening / closing machine 14 does not contact the granular material with which the flexible container bag 80 was filled. When the switch 14 comes into contact with the powder, the powder may adhere to the switch 14, or the switch 14 may not operate due to the adhered powder. According to this embodiment, since the opening / closing machine 14 does not contact a granular material, it is not necessary to wash the opening / closing machine 14 frequently. In addition, in the case where powders of different varieties are continuously conveyed, there is no possibility that powders of different varieties are mixed.

  After connecting the opening of the flexible container bag 80 and the chute 13, the work window 151 is closed.

  Next, the control board 35 is operated and the granular material with which the flexible container bag 80 was filled is thrown into the predetermined storage tank 90. FIG. The bag opening and conveying apparatus 1 may be configured such that an operator operates each of the bag opening machine 10 and the crane 20. However, it is more preferable that the bag opening and conveying apparatus 1 is configured such that the bag opening machine 10 and the crane 20 are automatically controlled by the control unit 30. Below, an operator demonstrates only the designation | designated of the storage tank 90 into which a granular material is thrown in, and the operation | movement after that is automatically performed by the control apparatus 30 is demonstrated.

  FIG. 10 is a diagram for explaining the operation of the bag-opening conveyance device 1. Here, reference numeral 90a indicates a charging port of the storage tank 90, reference numeral 91 indicates a lid covering the charging port 90a, and reference numeral 92 indicates a lid opening / closing machine. Reference numeral 93 denotes a guide for guiding the bag opening machine 10 so that the chute 13 is inside the charging port 90a when the bag opening machine 10 approaches the charging port 90a. Reference numeral 222 denotes a steadying device attached to the trolley 22 of the crane 20.

  First, the hoisting machine 221 is driven by the crane driving unit 32 (FIG. 5), and the bag opening machine 10 is lifted. In order to bring the bag opener 10 and the steady rest 222 into contact, the bag opener 10 is once lifted to the vicinity of the trolley 22.

  FIG. 11 is a view for explaining the steady rest device 222. The steady rest device 222 is a substantially rectangular frame in plan view (xy plane view). As shown in FIG. 11, the steady rest device 222 is configured to press the outer frame 12 of the bag opening machine 10 from four directions in a state where the bag opening machine 10 is lifted to the vicinity of the trolley 22. In addition, although a certain amount of shaking is prevented by the steady rest device 222, the main shaking prevention is performed by controlling the crane 20.

  Subsequently, the crane driving unit 32 (FIG. 5) drives the trolley 22 and the crane saddle 23 to horizontally transport the bag opening machine 10 to above the input port 90 a of the designated storage tank 90. The positioning of the bag opening machine 10 and the insertion port 90a may be performed by, for example, a mechanical or electrical switch, or may be performed using a sensor or the like. Alternatively, the movement distance may be calculated from the rotational speed of the motors of the trolley 22 and the crane saddle 23, and alignment may be performed while collating with the coordinates of the storage tank 90 registered in advance.

  When the horizontal conveyance of the bag opening machine 10 is completed, the hoisting machine 221 is driven by the crane drive unit 32 (FIG. 5), and the bag opening machine 10 starts to descend.

  When the distance between the bag opening machine 10 and the charging port 90a reaches a predetermined value, the lid controller 33 (FIG. 5) drives the lid opening / closing device 92 to open the lid 91 of the storage tank 90. The determination of the distance between the bag opening machine 10 and the insertion port 90a can be performed by a mechanical or electrical switch, a sensor, or the like, as described above. Alternatively, the descent distance may be calculated from the rotational speed of the motor of the hoist 221 or the like.

  The bag opening machine 10 is guided by the guide 93 so that the chute 13 is inside the insertion port 90a in plan view (xy plane view). The crane control unit 32 (FIG. 5) stops the descent of the bag opening machine 10 when the distance between the lower end of the chute 13 and the insertion port 90a reaches a predetermined value. The distance between the lower end of the chute 13 and the insertion port 90a can be determined in the same manner as described above.

  Subsequently, the bag opening machine control unit 31 (FIG. 5) drives the chute moving machine 16 to move the chute 13 downward. FIG. 12 is a diagram illustrating a state before the chute 13 moves. FIG. 13 is a diagram illustrating a state after the chute 13 has moved.

  As shown in FIG. 13, when the chute 13 moves downward, the lower end of the chute 13 enters a state inside the storage tank 90. This makes it difficult for the particles to spill out of the tank 90 when the particles are discharged from the chute 13.

  Further, as the chute 13 moves downward, tension is applied to the flexible container bag 80 connected to the chute 13. Thereby, the deflection of the flexible container bag 80 is removed, and it is possible to make it easy for the granular material to be discharged.

  Subsequently, the bag opening machine control unit 31 (FIG. 5) drives the opening / closing machine 14 to open the flexible container bag 80. FIG. 14 is a view showing a state where the opening / closing machine 14 is opened and the flexible container bag 80 is opened. Thereby, the granular material filled in the flexible container bag 80 is discharged from the chute 13 and is put into the storage tank 90. The bag opening machine control unit 31 (FIG. 5) drives the bottom impact machine 17 and the side impact machine 18 as necessary.

  When the discharge of the granular material is completed, the bag-opening conveyance device 1 performs the operations so far in the reverse order. That is, the opening / closing machine 14 is closed, the chute 13 is moved upward by the chute moving machine 16, and the hoisting machine 221 is driven to raise the bag opening machine 10. The lid 91 is closed by the lid opening / closing device 92, and the trolley 22 and the crane saddle 23 are driven to transport the bag opening machine 10 horizontally above the work table 95. Then, the hoisting machine 221 is driven to lower the bag opening machine 10 and the bag opening machine 10 is placed on the work table 95 again.

  Thereafter, the operator removes the flexible container bag 80 from the bag opening machine 10 and cleans the chute 13 as necessary.

[Effect of this embodiment]
FIG. 15 and FIG. 16 are diagrams for explaining a method of transporting a flexible container bag according to a virtual comparative example for explaining the effect of the present embodiment.

  In this comparative example, the worker W first hangs the flexible container bag 18 on the crane CR as shown in FIG. The worker W then climbs up to the storage tank 90 and approaches the input port 90a. The operator W operates the crane CR to bring the flexible container bag 80 close to the insertion port 90a. Then, as shown in FIG. 16, the operator W opens the lid 91 and opens the flexible container bag 80 while being hung on the crane CR. After opening the bag, the worker W returns to the ground, operates the crane CR, and lowers the flexible container bag 80.

  In this comparative example, the worker W needs to reciprocate between the ground and the storage tank 90. In addition, when the storage tank 90 is large, the worker W needs to perform work at a high place. Furthermore, since dust is generated when the flexible container bag 80 is opened, there is a problem that the working environment is poor.

  On the other hand, in the present embodiment, the bag opening / unloading apparatus 1 conveys the flexible container bag 80 together with the bag opening machine 10 to above the input port 90a of the storage tank 90 by the crane 20. And the switch 14 is controlled by the control apparatus 30, and a granular material is discharged | emitted from the chute | shoot 13 and thrown into the insertion port 90a. The operator only has to operate the control panel 35 on the ground. Therefore, it is not necessary for an operator to reciprocate between the ground and the storage tank 90. Also, workers do not have to work at heights and are not exposed to dust. That is, the work environment can be improved. In addition, transportation costs can be reduced by simplifying the work.

  Further, the bag-opening / conveying apparatus 1 uses the crane 20 to move the bag-opening machine 10 up and down and horizontally. Since the track of the crane 20 (such as the transverse gutter 21 and the traveling gutter 24) can be provided in the space above the equipment, the layout of the equipment is highly flexible.

[Other Embodiments]
As mentioned above, although embodiment about this invention was described, this invention is not limited only to the above-mentioned embodiment, A various change is possible within the scope of the invention.

  Although FIG. 1 shows an example in which a plurality of storage tanks 90 are arranged in a matrix, the arrangement of the storage tanks 90 is arbitrary. For example, the storage tanks 90 may be arranged in a line. Moreover, the storage tank 90 may be one.

  Moreover, although the case where the crane 20 was an overhead crane was demonstrated in the above-mentioned embodiment, the crane 20 may be a jib crane, for example.
