Description

The present invention relates to a powder and granular material bagging device that packs powder and granular material into flexible container bags.

Conventionally, a powder/granular material bagging device that packs powder/granular material into flexible container bags (hereinafter referred to as "flexible container bags") has been known (see, for example, Patent Document 1).

The powder bagging device holds a FIBC bag by hooking a lifting shoulder strap onto a hook, fills a predetermined amount of powder into the FIBC bag from a weighing hopper, and after filling the FIBC bag with powder, inserts the forks of a forklift into the shoulder strap of the FIBC bag, removes the shoulder strap from the hook, and then lifts the FIBC bag with the forklift and transports it away.

However, when the flexi-con bag filled with granular material is to be lifted and carried out by the forklift, the shoulder strap T must be manually removed from the hook 10 by the forklift driver or a dedicated worker, resulting in problems with workability.

In the powder and granular material bagging apparatus of the present invention, the bag holding members are long members that are arranged in parallel to each other and extend horizontally at a position between them and the filling chute, and have a cross-sectional shape that is open at least at the top, and a space is formed between the bag holding members and the shoulder strap of the flexible container bag hung on the bag holding members, into which the forks of a forklift can be inserted horizontally.Therefore, after filling and bagging the flexible container bag held by hanging the shoulder strap on the bag holding members, the forks of the forklift can be inserted horizontally into the space formed between the bag holding members and the shoulder strap and the forks can be raised, so that the shoulder strap of the flexible container bag can be transferred from the bag holding members to the forks without human intervention, and the flexible container bag can be lifted and carried away by the forklift.
Therefore, according to the powdery or granular material bagging device of the present invention, manual work can be omitted and the flexible container bags after being filled with powdery or granular material can be efficiently removed.

In the powder and granular material bagging apparatus of the present invention, a pair of bag holding members are supported in a cantilevered manner on a support member that is capable of moving up and down, so that when the forks are raised to lift the flexible container bag, even if the flexible container bag comes into contact with the bag holding members, the bag holding members can rise together with the flexible container bag, thereby mitigating the impact of the contact and preventing damage to the flexible container bag.

In the powder and granular material bagging apparatus of the present invention, the support member is attached to a movable member that is mounted on a pillar and can be raised and lowered, and a pulley is provided on the upper part of the pillar, one end of a wire hung on the pulley is connected to the movable member and the other end of the wire is connected to a balance weight.Therefore, when the forks are raised to lift the flexible container bag, even if the flexible container bag comes into contact with the bag holding member, the flexible container bag can be lifted without requiring a large force due to the action of the balance weight.
In addition, after the shoulder straps of the flexible container bag are handed over from the bag holding member to the fork and the flexible container bag is transported away by the forklift, the bag holding member, which has risen together with the flexible container bag, can be automatically and gently lowered to a predetermined height position by the action of the balance weight.

An embodiment of the present invention will be described with reference to the drawings.
Fig. 1 shows a schematic left side view of a powder/granular material bagging apparatus according to an embodiment of the present invention. Fig. 2 shows a cross-sectional view taken along the line B-B of the powder/granular material bagging apparatus shown in Fig. 1. Fig. 3 shows a schematic front view of the powder/granular material bagging apparatus shown in Fig. 1.

The powder and granular material bagging device 1 in the embodiment of the present invention includes a base 2, a support 3 erected on one side of the base 2, and a movable member 4 mounted on the support 3 so as to be movable up and down. The base 2 can be a platform scale.

The movable member 4 has plates 41 arranged on the left and right sides of the support 3, and rollers 42 rotatably arranged between the plates 41 in positions that sandwich the support 3 from the front and back, and can be raised and lowered relative to the support 3.

A pulley 31 is provided on the top of the support 3, and a wire 32 is hung on the pulley 31. One end of the wire 32 is connected to the movable member 4 behind the support 3, and the other end of the wire 32 is connected to a balance weight 33 arranged inside the support 3.

Dampers 34 are provided on both the left and right sides of the support 3, and the lower end of the plate 41 is connected to the dampers 34.

The powder and granular material bagging device 1 also includes a pair of bag holding hands 7 that are arranged horizontally and parallel to each other at a position between the filling chute 6 located at the lower end of the weighing hopper 5.

The bag holding hand 7 is an elongated member having a cross-sectional shape with at least the upper part being open. In this example, the bag holding hand 7 has a substantially U-shaped cross-sectional shape with left and right sides having different heights.
The bag holding hand 7 forms a space between the shoulder strap H of the flexible container bag F hung on the bag holding hand 7 and the bag holding hand 7, into which the forks of a forklift can be inserted horizontally.

A support member 8 extending in the left-right direction is attached horizontally to the front side of the plate 41 of the movable member 4 , and the support member 8 can be raised and lowered together with the movable member 4 relative to the support column 3 .
The bag holding hands 7 are supported horizontally in a cantilever manner on both the left and right sides of the support member 8, and are movable up and down together with the movable member 4 which moves up and down the support pillar 3.

Furthermore, the powder/granular material bagging apparatus 1 is provided below the filling chute 6 with a movable chute 62 to which the inlet portion of the flexible container bag F is attached.
The movable chute 62 is provided so as to cover the lower part of the filling chute 6 and extend downward.

FIG. 4 is an explanatory diagram of the movable chute of the powder/granular material bagging apparatus of FIG. 1, taken along the line CC.
An upper movable member 9 is connected to the movable member 4 above the movable member 4 and is provided integrally with the movable member 4 on the support 3 so as to be capable of ascending and descending.
The upper movable member 9 has plates 91 arranged on the left and right sides of the support 3, and rollers 92 rotatably arranged between the plates 91 in a position that sandwiches the support 3 from the front and back, and is capable of being raised and lowered relative to the support 3.

A pair of chute support members 93 extending in the front-rear direction are attached horizontally to the front side of the plate 91 of the upper movable member 9 .
The movable chute 62 is supported in a cantilever manner at the front ends of the pair of chute support members 93 and moves up and down together with the upper movable member 9 which moves up and down the support column 3 , and is capable of moving up and down relative to the filling chute 6 .

The movable chute 62 is supported at its upper part by a support shaft 94 at the front end of the pair of chute support members 93, and can swing in the direction in which the bag holding hand 7 extends, with the support shaft 94 as a fulcrum.

The lower end of the movable chute 62 is formed with a downward incline toward the direction in which the bag holding hand 7 is extended and in the direction in which the forklift retracts and the FIBC bag F is transported out.

In the example shown in Figure 4, the movable chute 62 is supported by the support shaft 94 at a position shifted toward the support pillar 3 from the center in the front-to-rear direction, but it can also be supported at the center position in the front-to-rear direction.
If the movable chute 62 is supported by the support shaft 94 at a position shifted toward the support pillar 3 from the center in the front-to-rear direction, the rear outer peripheral surface of the movable chute 62 can be abutted against an abutment member 95 provided behind it, thereby stabilizing the posture of the movable chute 62 when filling with powdered or granular material.

FIG. 5 shows an explanatory diagram of the clamping means for clamping the FIBC bag to the movable chute.
A pair of clamping means 65 formed by compression springs 66 are provided on the outer circumferential surface of the movable chute 62 .
The insertion opening of the flexible container bag F attached to the outer circumferential surface of the movable chute 62 is pressed and clamped by the clamping means 65 due to the action of the compression spring 66 .
In addition, in the drawings other than Figure 5, for ease of understanding, the dimensions of the inlet portion of the flexi-con bag F are shown larger than the dimensions of the movable chute 62, but in reality, it is pressed against the outer circumferential surface of the movable chute 62 by the clamping means 65 and clamped, as shown in Figure 5.

6 to 8 are explanatory front views showing how the flexible container bag is hoisted after being filled with powder or granular material.
The bag holding hand 7 is a long member having a cross-sectional shape with at least the upper part being open, so that a space is formed between the shoulder strap H of the FIBC bag F hung on the bag holding hand 7 and the bag holding hand 7 into which the forks T of a forklift can be inserted horizontally.
Therefore, as shown in FIG. 6, the forks T of a forklift are inserted horizontally into the space formed between the bag holding hand 7 and the shoulder strap H of the flexible container bag F hung on the bag holding hand 7.

Next, as shown in FIG. 7, the forks T of the forklift are raised, and the shoulder straps H of the flexible container bag F are transferred from the bag holding hands 7 to the forks T.
The bag holding hand 7 is a long member having a cross-sectional shape with at least the upper part being open, so that by raising the fork T of the forklift, the shoulder strap H of the FIBC bag F can be transferred from the bag holding hand 7 to the fork T without human intervention.

Then, as shown in FIG. 8, the forks T of the forklift are further raised to hoist the flexible container bag F and lift it up from the base 2.
At that time, even if the flexi-con bag F comes into contact with the bag holding hand 7, the bag holding hand 7 is capable of moving up and down together with the movable member 4, so that the bag holding hand 7 rises together with the flexi-con bag F, thereby mitigating the impact of the contact and preventing damage to the flexi-con bag F.

In addition, below the filling chute 6, a movable chute 62 to which the inlet of the FIBC bag F is attached is provided so as to cover the lower part of the filling chute 6 and extend downward, and the movable chute 62 is movable up and down relative to the filling chute 6, so that the FIBC bag F can be prevented from coming into contact with the filling chute 6 when it is lifted.

Furthermore, when the FIBC bag F is lifted, after the FIBC bag F comes into contact with the bag holding hand 7, the bag holding hand 7 and the movable chute 62 rise together, and the relative height positions of the movable chute 62 and the FIBC bag F do not change. Therefore, when the FIBC bag F is transported by the forklift, there is no problem in that the inlet of the FIBC bag F attached to the movable chute 62 becomes difficult to detach.

FIG. 9 is an explanatory view from the left side showing how the lifted flexible container bag is unloaded after being filled with powder or granular material.
As shown in FIG. 8, the forks T of the forklift are raised to hoist the flexible container bag F, and then, as shown in FIG. 9, the forklift is moved backward to carry out the flexible container bag F.

At that time, the upper part of the movable chute 62 is supported by a support shaft 94, and the movable chute 62 can swing around the support shaft 94 in the direction in which the bag holding hand 7 is extended. Therefore, by tilting the movable chute 62, the insertion port of the FIBC bag F attached to the movable chute 62 can be automatically removed without manual intervention.

The lower end of the movable chute 62 is formed with a downward incline toward the direction in which the bag holding hand 7 is extended and the FIBC bag F is transported out, so that the insertion opening of the FIBC bag F can be removed without getting caught.

Furthermore, the inlet portion of the FIBC bag F is pressed by the clamping means 65 due to the action of the compression spring 66 and clamped to the outer circumferential surface of the movable chute 62, so that the inlet portion of the FIBC bag F clamped to the outer circumferential surface of the movable chute 62 can be automatically pulled out from the clamping means 65.

FIG. 10 is an explanatory front view of the flexible container bag after it has been filled with powder and granular material and then unloaded.
As shown in FIG. 10, after the flexible container bag F has been discharged, the bag holding hand 7 is lowered together with the support member 8 to a predetermined height position.
At this time, as shown in Figure 1, a pulley 31 is provided on the upper part of the support 3, a wire 32 is hung on the pulley 31, one end of the wire 32 is connected to the movable member 4 behind the support 3, and the other end of the wire 32 is connected to a balance weight 33 arranged inside the support 3, so that the bag holding hand 7, which has risen together with the FIBC bag F, can be automatically and gently lowered to a predetermined height position.

In addition, dampers 34 are provided on both the left and right sides of the support 3, and the lower end of the plate 41 of the movable member 4 is connected to the dampers 34, so that the impact when the bag holding hand 7 is lowered to a predetermined height position can be mitigated.

In the powdered or granular material bagging apparatus according to the embodiment of the present invention, the bag holding hands 7 are elongated members which are provided in a pair extending horizontally in parallel to each other at a position between them and the filling chute 6, and have a cross-sectional shape with at least an upper portion open. A space into which the forks T of a forklift can be inserted horizontally can be formed between the bag holding hands 7 and the shoulder straps H of the flexi-con bag F hung on the bag holding hands 7. Therefore, after the flexi-con bag F held by the shoulder straps H hung on the bag holding hands 7 is filled with powdered or granular material and bagged, the forks T of the forklift can be inserted horizontally into the space formed between the bag holding hands 7 and the shoulder straps H, and the forks T can be raised, so that the shoulder straps H of the flexi-con bag F can be transferred from the bag holding hands 7 to the forks T without manual intervention, and the flexi-con bag F can be lifted up and carried out by the forklift.
Therefore, according to the powdery or granular material bagging device in the embodiment of the present invention, manual work can be omitted and the flexible container bag F after being filled with powdery or granular material can be efficiently unloaded.

In the embodiment of the present invention, the bag holding hand 7 has an approximately U-shaped cross section with different heights on the left and right, but it can also have an approximately L-shaped cross section. If the bag holding hand 7 has an approximately U-shaped cross section with different heights on the left and right, it can handle FIBC bags F with short shoulder straps H, just like the bag holding hand 7 with an approximately L-shaped cross section.

In the embodiment of the present invention, the bag holding hand 7 has a cross-sectional shape that is open at least at the top, and can have any cross-sectional shape, such as a roughly V-shape, as long as it forms a space between the shoulder strap H of the FIBC bag F hung on the bag holding hand 7 and the shoulder strap H into which the fork T of a forklift can be inserted horizontally.

In the above embodiment of the present invention, the lower end of the movable chute 62 is formed in a downward incline toward the direction in which the bag holding hand 7 is extended, that is, toward the direction in which the forklift retreats and the flexi-con bag F is transported out, but it can also be formed in an arc shape toward the direction in which the bag holding hand 7 is extended.
Even if the lower end of the movable chute 62 is formed in an arc shape toward the direction in which the bag holding hand 7 is extended, the inlet portion of the flexi-con bag F attached to the movable chute 62 can be removed without getting caught.

In addition, if the lower end of the movable chute 62 is formed in an arc shape toward the direction in which the bag holding hand 7 is extended, the movable chute 62 does not necessarily need to be supported so that it can swing. Even in this case, when the FIBC bag F is lifted and carried out by the forklift, the inlet portion of the FIBC bag F attached to the movable chute 62 can be automatically removed without manual intervention.

In the embodiment of the present invention, a plurality of flexible container bags F can be stocked in the bag holding hand 7 as shown in FIGS.
If a plurality of flexi-con bags F are stocked in the bag holding hand 7, after a flexi-con bag F filled with powder or granular material is transported, the stocked flexi-con bag F can be shifted on the bag holding hand 7 and the inlet portion can be attached to the movable chute 62, thereby improving workability.

In the embodiment of the present invention, the powder/granular material bagging device 1 can be a separate device independent of the weighing hopper 5 and the filling chute 6, or can be an integrated device.

The above describes an embodiment of the present invention, but the present invention is not limited to the above embodiment, and the configuration can be modified as appropriate without departing from the scope of the invention.

The powder/granular material bagging device of the present invention is extremely useful because it eliminates manual work when unloading flexible container bags after they have been filled with powder/granular material, and enables efficient unloading of flexible container bags.
