Description

  The present invention relates to a granular material supply system and a granular material supply method using a container bag for storing a granular material such as powder or granular material.

  Container bags made of paper bags, metal cans, cloth or resin films are used for storing and transporting powder particles such as welding fluxes. In recent years, flexible container bags that can be stored, transported, and discharged in large quantities are often used. The flexible container bag is composed of a container outer bag having a filling opening on the upper surface and a discharge opening on the lower surface, and an inner bag having a filling sleeve at the top of the storage barrel and a discharge sleeve at the bottom. By the time the container is stored, the inner bag is inserted into the container outer bag, and the filling sleeve projects upward from the filling opening on the upper surface of the container outer bag. The granular material is poured into the storage barrel of the inner bag from the upper opening of the filling sleeve. The suspension rope is fixed to the side surface of the container outer bag, and the flexible container bag filled with the granular material is carried by hanging the suspension rope on the hook of the crane. When using the granular material of the flexible container bag, the flexible container bag is suspended at the place of use, and the granular material in the storage barrel of the inner bag is caused to flow down from the discharge sleeve. An example of this type of flexible container bag is described in Patent Document 1.

  The granular material filled in the storage barrel of the inner bag can be discharged easily and in a short time through the discharge sleeve at the bottom of the inner bag. Moreover, moisture absorption of the granular material with which the flexible container bag was filled can be prevented by making an inner bag into the bag of the film raw material which does not let moisture pass.

First Embodiment FIG. 1 is a perspective view showing a container outer bag 1 and an inner bag 5 of a container bag of a granular material supply system according to a first embodiment of the present invention. FIG. The bag 1 and the inner bag 5 are shown in FIG.

  The container outer bag 1 is made of a flexible material, and its original shape is a soft and strong bag. When air is blown into the inside, a substantially cylindrical filling cover 3 and a discharge cover 4 having a small diameter are continuously formed above and below the thick cylindrical body cover 2. The filling cover 3 is continuous with the filling opening on the upper surface of the body cover 2, and the discharge cover 4 is continuous with the discharge opening on the lower surface. Upper diaphragm lids 10a to 10d are provided outside the filling cover 3 around the filling opening, and lower diaphragm lids 11a to 11d are arranged outside the discharge cover 4 around the discharge opening. An upper diaphragm string 12 for squeezing and closing it is attached to the upper diaphragm lids 10a to 10d, and a lower diaphragm string 13 for squeezing and closing it to the lower diaphragm lids 11a to 11d. Hanging ropes 14 and 15 are attached to the side surface of the container outer bag 1.

  The inner bag 5 is made of a relatively thin flexible material having high flexibility, and its original form is a flat sheet. When air is blown into the inside, the upper and lower sides of the substantially cylindrical thick storage cylinder 6 become a three-dimensional structure in which a small-diameter substantially cylindrical filling sleeve 7 and a discharge sleeve 8 are formed. The filling sleeve 7 and the discharge sleeve 8 are continuous with the storage cylinder 6. The lower end of the discharge sleeve 8 is closed by thermocompression bonding 9.

  Put the inner bag 5 in the container outer bag 1 and pass the discharge sleeve 8 through the discharge guide 4. Put the storage cylinder 6 into the cylinder cover 2 and the filling sleeve 7 into the filling cover 3, and then discharge the discharge sleeve 8. A zigzag fold is made together with the guide 4, inserted into the body cover 2 through the filling opening of the container outer bag 1, the lower squeeze lids 11 a to 11 b are squeezed and closed with the lower squeeze string 13, and the inner bag 5 When air is blown into the interior, a container bag having the form shown in FIG. 2 is obtained.

  A container bag having the form shown in FIG. 2 is placed on a pallet, and the filling guide 3 and the filling sleeve 7 are maintained in a substantially upright cylindrical shape with a hook or a clamper. Pour into the storage cylinder 6 in the cylinder cover 2 from the upper opening. That is, the container bag is filled with welding flux. When the storage cylinder 6 is filled with a required amount of welding flux, the internal air is discharged from the upper end of the filling sleeve 7 and the upper end of the filling sleeve 7 is hermetically closed by the thermocompression bonding 19.

  As a result, the container bag has the form shown in FIG. Next, the filling guide 3 is zigzag-folded together with the filling sleeve 7 and inserted into the case cover 2 through the filling opening of the case cover 2, and the upper drawing lids 12 squeeze the upper drawing lids 10 a to 10 d. When closed, the container bag shown in FIG. 4 is filled with a welding flux and has a transfer configuration.

  When the welding flux of the container bag shown in FIG. 4 is discharged (supplied) to the flux supply hopper, the upper drawstring 12 is loosened to open the filling opening on the upper surface of the trunk cover 2 and the filling sleeve 7 immediately below the filling sleeve 7 is filled. 3 is pulled upward together, and a rod body 17 as a drop restraint tool is bound to the filling sleeve 7 by a binding rope 18 as a mooring means. The rod body 17 is longer than the width of the filling opening on the upper surface of the trunk cover 2 of the container outer bag 1. Next, the suspension ropes 14 and 15 are hooked on a hook of a crane (not shown), and the container bag is transported above the flux supply hopper by the crane.

  Then, the lower drawstring 13 is loosened and the lower drawdown lids 11a to 11d are opened, that is, the discharge opening on the lower surface of the body cover 2 is opened, and the discharge sleeve 8 of the inner bag 7 is pulled down together with the discharge guide 4 The bottom thermocompression bonding 9 (FIG. 1) is excised. As a result, the welding flux in the storage barrel 6 of the inner bag 5 begins to flow into the flux supply hopper through the discharge sleeve 8. FIG. 5 shows the form of the container bag at this time. By piercing the storage barrel 6 with a stab or drilling tool through the vent hole 16 and opening the vent hole in the inner bag 5, air enters the storage barrel 6 and the flow rate of the flux for welding is increased, so that the flux discharge operation becomes efficient. . Even when a downward load is applied to the inner bag 5 due to the weight of the welding flux in the inner bag 5 when discharging the welding flux, the length of the rod 17 is longer than the width (diameter) of the filling opening of the trunk cover 2. This is applied to the upper surface of the trunk cover 2 of the container outer bag 1 over the filling opening, so that the inner bag 5 does not fall downward from the container outer bag 1 and discharge of the welding flux proceeds smoothly.

Second Embodiment The container bag used in the second embodiment of the present invention has the same form as that of the first embodiment, but the aspect of the powder supply method using the container bag is different. In the granular material supply method (first aspect) of the first embodiment described above, when the container bag is filled with the welding flux and the upper end of the filling sleeve 7 is airtightly closed by the thermocompression bonding 19 as shown in FIG. The filling sleeve 7 is zigzag-folded together with the filling guide 3 and inserted into the filling opening of the body cover 2, and the upper throttle lids 10 a to 10 d are throttled and closed with the upper throttle string 12 to obtain the package shown in FIG. When using the welding flux, the container bag is carried over the flux supply hopper, but before or after that, the filling opening is opened and the filling sleeve 7 is pulled out together with the filling guide 3 and tied to the filling sleeve 7 and tied to the rope 18. Tie the rod 17 with. Then, the discharge opening of the container bag carried above the flux supply hopper is opened, the discharge sleeve 8 is pulled out together with the discharge guide 4, and the thermocompression bonding 9 (FIG. 1) at the lower end of the discharge sleeve 8 is cut off. This form is shown in FIG.

  However, in the powder supply method of the second aspect of the present invention, immediately after filling the welding flux as shown in FIG. 3 and sealing the upper end of the filling sleeve 7 with the thermocompression bonding 19, as shown in FIG. The rod body 17 as a drop restraint tool is bound to the filling sleeve 7 with a binding rope 18 as an anchoring means, and the upper throttle lids 10a to 10b are closed with the upper throttle string 12. Then, the rod body 17 is placed on the aperture lids 10a to 10b.

When using the flux, the discharge opening of the trunk cover 2 is opened, the discharge sleeve 8 is pulled out together with the discharge guide 4, and the thermocompression bonding 9 (FIG. 1) at the lower end thereof is cut off. As a result, the welding flux in the storage barrel 6 of the inner bag 5 begins to flow into the flux supply hopper through the discharge sleeve 8. FIG. 7 shows the form of the container bag at this time.
In both the first and second aspects described above, the rod body 17 that is a drop restraint tool is longer than the width (diameter) of the filling opening on the upper surface of the trunk cover 2. When the length of the rod body 17 is less than the width (diameter) of the filling opening, when discharging the powder body (for example, welding flux), the weight of the powder body is applied to the rod body 17 so that the rod body 17 is in the filling opening. The inner bag 5 falls from the container outer bag 1 and cannot be discharged from the discharge sleeve at the lower end of the inner bag. If the length of the rod body 17 exceeds 500 mm, it takes time to attach and detach the upper end of the inner bag to the filling sleeve 7, and the work efficiency deteriorates. Therefore, the length is preferably 400 mm or less.
Further, for the purpose of preventing and dropping the rod body 17, two rod bodies 17 may be used and placed on the filling opening in a cross shape. Furthermore, the shape of the rod 17 may be either a cylinder or a prism. Further, a non-slip seal may be attached to the portion of the rod body 17 that binds the binding rope 18 that is the mooring means, or a small protrusion group, a circumferential groove, and a circumferential ridge may be provided so that the binding portion does not move. Moreover, you may provide a flange in the both ends of the rod body 17 so that a binding part may not remove | deviate. The binding method of the tie rope 18 is not particularly limited, but for the purpose of preventing detachment, a portion immediately before winding the filling sleeve 7 after winding the filling sleeve 7 around the rod body 17 more than once and a tip portion after winding. It is also preferable to tie them tightly with a rope.
When the inner bag 5 is installed inside the container outer bag 1, the inner bag 5 is sufficiently inflated with air or the like before filling the granular material for the purpose of uniformly spreading the inner bag 5 inside the container outer bag 1. It is preferable that the discharge sleeve 8 is accommodated in the vicinity of the discharge opening so that the discharge sleeve 8 of the bag 5 can be smoothly taken out from the discharge opening of the trunk cover 2. For the purpose of preventing moisture absorption, it is preferable to use a polyethylene film, a polyethylene laminate, or the like for the inner bag 5.

  Specific examples of the present invention will be described below. The diameter is 620 mm, the height is 700 mm, the diameter of the filling opening and the filling sleeve 7 is about 400 mm, the length of the filling sleeve 7 is 600 mm, the diameter of the discharge opening and the discharge sleeve 8 is about 300 mm, and the length of the discharge sleeve 8 is 1200 mm. JIS Z 3352 SAAB1 as a granular material is taken out of the filling sleeve 7 of the inner bag 5 from the filling opening of the container bag of one embodiment of the present invention in which the inner bag 5 is accommodated in the container outer bag 1. After filling 150 kg of welding flux equivalent to the above, the filling sleeve 7 is wound around a stainless steel pipe having a diameter of 19 mm and a length of 450 mm three times, and the stainless steel pipe is placed on the filling opening, and then the upper surface of the container outer bag 1 In the container bag whose opening is closed with the drawstring 12, an air hole is made in the surface portion of the inner bag 5 exposed from the vent hole 16, With the container bag suspended by the ropes 14 and 15, the discharge opening of the container outer bag 1 is opened, the discharge sleeve 8 of the inner bag 5 is taken out from the discharge opening, and the thermocompression bonding portion at the lower end of the discharge sleeve 8 is cut. As a result of discharging the welding flux, the inner bag 5 did not fall from the container outer bag 1 and the welding flux was discharged smoothly, the working time was very short, and the working efficiency was improved.

  On the other hand, in a flexible container bag in which a conventional flexible container bag is filled with 150 kg of welding flux and then the inner sleeve filling sleeve and the upper lid of the container outer bag are bound and fixed together, the welding flux is discharged. Sometimes the inner bag 5 dropped and the welding flux could not be discharged.
