Description

  The present invention relates to a bag filling auxiliary device used for filling a bag with a filling material.

Conventionally, sandbags are produced by filling sandbags with filling materials such as earth and sand in civil engineering work and construction work. In addition, flexible container bags for pulverized and crushed materials such as wood and construction waste, or powdered filling materials such as compost, feed, grains, resin pellets, glass cullet, etc. It is performed to fill the bags.
When filling the above-mentioned filling material into a bag or the like, in a factory or the like, attach a bag opening to a large hopper device and fill the bag with the filling material, then use a belt conveyor or the like. It is transported and the filling operation and the transporting operation are performed.

However, the installation of the hopper device and the belt conveyor as described above at various construction sites such as civil engineering works and construction works, or at the earthworks, the material storage, and the material storage are various viewpoints such as cost and installation space. Therefore, in general, bagging is performed manually, or bagging is performed using a heavy machine such as a backhoe or a power shovel.
In particular, the filling operation of filling material into a large bag is difficult by manual operation, and various auxiliary tools have been proposed.

For example, Patent Document 1 below proposes an opening fixture for a residual soil storage bag that is used when the residual soil is put into a storage bag.
The opening fixture includes a frame that houses the storage bag, and a plurality of hook members that hook the other end of the hook strap attached to the opening end of the storage bag. The frame body includes a plurality of pipe-like struts and a plurality of pipe-like cross members, and a latch member is detachably fixed to the cross members.
In the opening fixture configured as described above, the retaining strap of the storage bag can be retained by the retaining member, so that the opening of the storage bag can be held in an expanded state.
The filling operation of the remaining soil into the storage bag using this opening fixture is configured to fill the storage bag with the remaining soil by introducing the remaining soil from the opening held in the expanded state as described above. . In addition, after the filling is done, remove the retaining strap of the storage bag from the retaining member of the opening fixture, and hook the lifting rope of the storage bag on the hook portion of the bucket such as the backhoe and lift it The storage bag after filling can be taken out from the opening fixture.

Moreover, in the following patent document 2, a latch member for latching a latching body such as a latch string of a granular material storage bag for storing powder particles such as earth and sand and grains, and a granular material guide having the latch member Has been proposed.
This granular material guide is provided with a cylindrical body formed in a funnel shape, and a hooking member disposed so as to extend symmetrically and substantially horizontally at two locations on the outer surface of the cylindrical body.
The filling operation of the granular material into the storage bag using the granular material guide tool configured as described above is performed by first hooking the wire attached to the upper end portion of the cylindrical body onto a bucket such as a hydraulic excavator and the like. The cylinder is suspended in this state, and in this state, the lower part of the cylinder is accommodated in the opening of the bag, the cylinder is inserted into the opening of the bag, and the hanging strap of the bag is attached to the hook. Hang on the stop member.
Next, the wire is removed from the bucket, and a granular material such as earth and sand is introduced from the upper opening of the cylinder using a bucket of a hydraulic excavator. After filling the cylinder with a predetermined amount of powder, the wire is again hooked on the bucket and lifted, and the bag is moved to a desired position while attached to the powder guide. Yes. As a result, the powder filled in the cylinder is put into the bag by its own weight, and the bag filled with the powder can be moved while attached to the cylinder. Has been.

Patent Document 3 below proposes a sandbag that is filled with a filling material such as sand, earth and sand, and is used as a weight, earth retaining, damming, container bag, etc., and a method for producing a sandbag using this sandbag. Has been.
In this method of manufacturing a sandbag, the opening of the sandbag is spread and placed in a rectangular parallelepiped-shaped manufacturing frame having upper and lower openings, and sand, earth and sand, etc. are filled as filling material. Further, after filling the filling material, the opening of the sandbag is closed and tied with a string, the suspension rope of the sandbag is hooked on the hook of the crane, and the sandbag is lifted and taken out from the production frame.
Japanese Patent Laying-Open No. 2005-82209 (see FIG. 1) JP 2008-7183 A (refer to FIGS. 3 to 6) JP 2008-63837 A (see FIGS. 3 and 4)

However, the operation of filling the storage bag with the residual soil storage bag opening fixture described in Patent Document 1 includes storing the residual soil storage bag in a frame formed by a pipe-like column and a cross member. The opening portion of the stored storage bag is hooked on the hooking member, the opening portion is held in an open state, and the remaining soil is charged. In this state, the storage bag has only an opening at its upper end, and there is nothing to restrain or regulate the lower part of the storage bag. The filling amount may be different for each filled storage bag.
Also, after filling the storage bag with the remaining soil, when the storage bag is lifted and moved from the frame, the storage bag is caught on the frame, the frame falls down, or the There is a risk of lifting with the hanging means, and improvement in workability has been desired.

  Moreover, when filling a granular material into a bag body using the granular material guide tool described in Patent Document 2, the attachment of the bag body to the granular material guide tool is performed by the granular material guide tool. In the state where the wire attached to the cylinder body is hooked on a bucket such as a hydraulic excavator and the cylinder body is suspended in the air, the cylinder body is inserted into the opening of the bag body, and the retaining cord of the bag body is hooked. Since it is necessary to hang and attach to a stop member, and this granular material guide is in an unstable state suspended in the air, workability is poor.

  Further, in the above-mentioned granular material guide, when a bag is attached to the granular material guide, the bucket such as a hydraulic excavator is tilted (lowered) when the granular material is filled in the bag. Then, the granular material guide is placed on the floor, the wire of the granular material guide is removed from the bucket, and the granular material such as earth and sand is removed from the upper opening of the cylindrical body of the granular material guide. A predetermined amount is filled using a bucket or the like. When the bag is moved after the filling, the wire is again hooked on the bucket and lifted, and the bag is moved to a desired position while being attached to the powder guide, and the powder is moved. The bag string is removed from the particle guide, the powder guide is lifted, and the bag to be filled next is attached. In such a configuration, the attachment and detachment of the powder guide member to the bucket of the wire, and the attachment and detachment work of the hanging strap of the bag body to the powder guide device are complicated, further improving workability. Was desired.

  Moreover, in the method for producing a sandbag described in Patent Document 3, it is described that the sandbag is lifted and taken out from the production frame used for filling the sandbag with the filling material. In the state filled with the material, the sandbag expands in the production frame and is in close contact with the production frame. In such a state, if the sandbag is lifted and taken out from the production frame, it cannot be removed smoothly and the production frame may fall down or be lifted together with the production frame. Improvement was desired.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an auxiliary device for bag filling that can improve the workability of the filling operation of the filling material into the bag while having a simple structure. .

  In order to achieve the above object, a bag filling auxiliary device according to the present invention is a bag filling auxiliary device used to fill a bag with a filling material, and is opened up and down to accommodate the bag. A cylindrical main body is provided, and the cylindrical main body is provided with a collar portion extending outward from the outer peripheral edge at the lower end thereof.

Here, the filling material may be any material such as earth and sand, pulverized or crushed material such as wood or construction waste, or compost, feed, grains, resin pellets, glass cullet and the like.
Moreover, the bag accommodated in the cylindrical main body is a sandbag bag for filling earth and sand, a flexible container bag for filling and transporting various filling materials as described above, or various fillings for filling. Any storage bag for filling and storing the material may be used.

The auxiliary device for filling a bag of the present invention may include a restraining means for restraining an opening end portion of the bag accommodated in the cylindrical main body and folded.
In the bag filling auxiliary device provided with the restraining means, the restraining means may be constituted by a retaining ring that tightens the folded back end of the bag from the outer periphery.

In the bag filling auxiliary device of the present invention, a string locking tool for locking a suspension string provided on the bag may be provided on the outer upper end of the cylindrical main body.
In the bag filling auxiliary device of the present invention, the cylindrical main body may have a substantially circular shape or a substantially regular polygonal shape of hexagon or more in plan view.

According to the bag filling auxiliary device according to the present invention, the bag can be accommodated from the opening above the cylindrical main body that opens up and down, and the bag can be filled with the filling material. Thereby, since the bag is regulated by the inner peripheral side wall of the cylindrical main body, for example, the filling amount does not vary for each bag filled with the filling material, and a uniform amount of filling material is provided for each bag. And each bag can have the same shape. Therefore, it is possible to stack the bags after filling the filling material in an orderly manner and without collapsing during storage, transportation or construction.
Moreover, since it is not necessary to lift the cylindrical main body after the cylindrical main body is installed at a predetermined position, the workability of the filling operation of the filling material into the bag can be dramatically improved. That is, after the bag is accommodated and filled with the filling material from the upper opening of the cylindrical main body, the bag after filling with the filling material is extracted by a heavy machine or the like, and is applied to a predetermined storage place or site. The bag is moved, and again, the bag is accommodated in the cylindrical body and filled with the filling material, such as filling operation, movement of the bag after filling the filling material moves the tubular body. Without repeating.

Further, since the outer peripheral edge of the lower end of the cylindrical main body is provided with a flange extending outwardly, the stability of the cylindrical main body is enhanced. Thereby, for example, when filling the filling material into the bag with a heavy machine such as a backhoe or a power shovel, the cylindrical main body does not fall down.
Furthermore, for example, by placing a weight or the like on the heel portion or depositing a filling material such as earth and sand, the stability is further improved, and the heel portion is the foundation of the ground or the like. It functions as a fixing portion for firmly fixing the cylindrical main body to the surface. Thus, as described above, after filling the filling material, when the bag is pulled out from the cylindrical main body, the cylindrical main body falls down or the cylindrical main body is pulled up together with the bag. Can be prevented. In addition, as described above, when sediment or the like is deposited on the eaves by using a heavy machine or the like, sediment or the like may enter the tubular body. Since the lower part is open, even when it is necessary to move the cylindrical main body, earth or sand does not remain in the cylindrical main body.
In addition, because it has a shape that opens up and down, for example, when installed on the foundation of the ground, etc., compared to the cylindrical body of which the lower end is closed, it can absorb the unevenness of the ground, etc. Can be reduced.

In the bag filling auxiliary device according to the present invention, provided with a restraining means for restraining the opening end portion of the bag accommodated and folded back in the cylindrical main body, the opening end portion of the bag is restrained. Therefore, when the filling material is put into the bag, the bag is prevented from slipping into the cylindrical main body or falling off into the cylindrical main body. And workability can be improved.
In the bag filling auxiliary device provided with the restraining means, if the restraining means is constituted by a retaining ring for fastening the folded open end portion of the bag from the outer periphery, the folded open end portion of the bag becomes the outer periphery. Since it is tightened by a retaining ring over the entire circumference, the opening end of the bag is firmly fixed and held, and the above-described bag slippage and drop can be reliably prevented.

In the bag filling auxiliary device according to the present invention, if a string locking tool for locking the suspension string provided on the bag is provided at the outer upper end of the cylindrical main body, the following is performed. Has an effect. In particular, when a bag such as a large sandbag or flexible container bag is accommodated in the cylindrical main body and the opening end thereof is fixed to the upper end of the cylindrical main body, the opening end of the bag is When it comes off and falls into the cylindrical main body, the work of picking up the bag is troublesome and difficult because of its large size. Since it is provided, it does not fall off and is excellent in workability.
Moreover, this string latching tool functions also as an object for the bag holding | maintenance which prevents the shift | offset | difference and fall of the above bags.
Further, when the bag filling auxiliary device is suspended by a heavy machine or the like, for example, by suspending a suspension belt or the like for hanging the bag filling auxiliary device or the like by a heavy machine or the like to the string locking tool. It also functions as a hanging part.

In the bag filling auxiliary device according to the present invention, if the cylindrical main body has a substantially circular shape or a substantially regular polygonal shape of hexagonal shape or more in plan view, a large cylindrical (round type) sandbag bag is provided. It is suitable for a cylindrical bag such as a so-called 1-ton sandbag or a large cylindrical flexible container bag. That is, it is possible to efficiently fill the filling material into the cylindrical bag.
Further, for example, the rigidity is increased as compared with a cylindrical main body such as a square cylindrical shape.

The workability of the filling work of earth and sand es into the bag 4 can be dramatically improved.
Moreover, since the surroundings of the sandbag bag 4 are regulated by the inner peripheral side wall of the cylindrical main body 10, the filling amount does not vary for each bag filled with the earth and sand es, and a uniform amount of earth and sand es can be obtained. Each sandbag bag 4 can be filled and a sandbag 5 having the same shape can be easily manufactured. Therefore, the sandbags 5 can be stacked in an orderly manner without collapsing at the time of construction on a civil engineering site.

Further, since the flange portion 13a extending outward is provided around the outer peripheral edge portion 11b at the lower end of the cylindrical main body 10, the stability of the cylindrical main body 10 is enhanced. Thereby, as mentioned above, when filling the sandbag bag 4 with the earth and sand es by the excavator excavator 2, the cylindrical main body 10 does not fall down.
Furthermore, as described above, by depositing earth and sand es on the flange portion 13a, the stability is further improved, and the flange portion 13a firmly attaches the cylindrical main body 10 to the base bs surface. It functions as a fixing part for fixing. Thus, as described above, when the sandbag 4 is extracted from the cylindrical main body 10 after filling with the sand and sand es, the cylindrical main body 10 falls down, or the cylindrical bag together with the sandbag 4 (the sandbag 5). It is possible to prevent the main body 10 from being pulled up. In addition, as described above, when the earth and sand es is deposited in the cylindrical main body 10 when the earth and sand es is deposited on the brim 13a by the excavator excavator 2, the cylinder as described above. Since the lower part of the cylindrical main body 10 is open, earth and sand es do not remain in the cylindrical main body 10 even when it is necessary to move the cylindrical main body 10.
Moreover, since it is made into the shape opened up and down, for example, compared with the thing of the cylindrical body with which the lower end was obstruct | occluded, when installing in foundations bs, such as the ground, the unevenness of the ground etc. can be absorbed, and cylindrical It can reduce that the main body 10 inclines.

Moreover, the bag filling auxiliary device 1 according to the present embodiment includes a retaining ring 20 that tightens the extended portion 4d of the sandbag 4 accommodated in the cylindrical main body 10 and folded back from the outer periphery. Accordingly, since the extended portion 4d of the sandbag 4 is restrained, when the sand and sand es is put into the sandbag 4, the sandbag 4 is displaced into the cylindrical main body 10 or the sandbag 4 is detached. Thus, it is possible to prevent the tube body 10 from falling into the tubular main body 10 and improve workability.
Furthermore, since a pair of string locking tools 14 and 14 are provided at the outer upper end of the cylindrical main body 10, the hanging strings 4b and 4b of the sandbag 4 can be locked. As a result, it is possible to prevent the slipping and dropping of the sandbag 4 as described above.
