Description

[Detailed description of the invention] (Field of application of the invention) This invention is a sheet-type device that is used as an aid for bulk transportation of multiple bag cargoes, etc., and can unpack a large number of bag cargoes, etc. in their original packaging. This invention relates to an unpacking hook that can prevent damage to cargo such as bag cargo when unpacking a transport device.

(Background of the idea) Conventionally, in order to transport bags filled with cement, fertilizer, etc., the bags were piled up in multiple stages on a pallet without falling apart, and the bags were stacked together in one pile, and then transported as they were. Generally, the bag cargo is loaded together with the pallet onto a truck or ship, and the bag cargo is unloaded together with the pallet at the destination. That is, the pallets are used as auxiliary tools for bulk transportation, and after transportation, used pallets are usually collected and reused.

However, when transporting a large amount of bag cargo, etc., a large number of pallets are required, and since the pallets themselves are bulky and heavy, the effort and expense required to collect them is considerable. There was a problem with making it work.

In order to solve these difficulties, many sheet-type conveyors have recently been proposed as auxiliary tools for bulk conveyance of multiple bags of cargo, etc., in place of the above-mentioned pallets.

FIG. 4 shows an example of such a carrier, and the figure shows its unfolded state.

In the figure, 1 indicates a rectangular body cloth made of a resin sheet or synthetic fiber sheet that is slippery and strong, such as polypropylene, polyethylene, etc.
A slit 2 is provided in the center along the longitudinal direction.

Reference numeral 3 indicates a pair of hangers sewn to protrude from both ends of the body cloth 1 so as to sandwich the slit 2, and the hangers 3 are made of the same material as the body cloth 1 or made of a sheet material having strength as a hanging belt. The oblong band is sewn to the back side of the trunk cloth 1 so that the entire weight of the bag cargo is uniformly applied to the trunk cloth 1 during cargo handling. In addition, the reason why a pair of hangers 3 are provided at each end of the trunk cloth 1 is that during cargo handling, a hook of a crane or the like is hung on each hanger 3 to hang the bags at four points, so that bag cargo stacked in multiple tiers can be hung horizontally. This is to achieve balance.

Reference numeral 4 indicates reference lines provided at regular intervals in the width direction of the central region of the body cloth 1, within which the bag cargo or the like is placed. Note that the distance between the pair of reference lines 4 is determined according to the standards of commercially available pallets and the like. Slightly inside the pair of reference lines 4, pull-out hands 5 for widening the tear in the slit 2 are sewn to the body cloth 1 so as to protrude from both ends of the body cloth 1. The pull-out handle 5 is formed by stitching a belt-like sheet made of the same material as the body cloth 1 or having strength as a hanging belt to the back side of the body cloth 1 in a crossed manner. Therefore, when applying a tensile force to the puller 5 to widen the tear in the slit 2, the trunk cloth 1 on which the bag cargo, etc. is placed
A uniform force will be applied to the center of the

Reference numeral 6 indicates a tie string provided at one end of the body cloth 1 so as to sandwich the slit 2. When packing bag cargo, this knot is attached to a knot ring 7 provided opposite the other end of the body cloth 1. The bag cargo is packed by tying the string 6.

In addition, as another conveyance sheet body, the above-mentioned body cloths are sewn together in a cross shape, and in the center of one body cloth,
A slit is provided along the longitudinal direction, and further,
Some have a structure in which a pair of hanging handles are provided at both ends of one of the body cloths, and a pair of handles are provided at both ends of the other body cloth.

According to the conveyance sheet body constructed as described above, the bag cargo, etc. are stacked in multiple stages in the center of the body cloth 1 and packed by the body cloth 1 (hereinafter referred to as such). A unit of transportation in which a large number of bag cargoes are packed together using a conveyor sheet is called a transportation unit).

During cargo handling work, a slinging rope or the like is passed through each of the above-mentioned lifting hands 3, and the objects are hung together on a hook of a crane or the like, so-called one-point hoisting. Pass the above-mentioned slinging rope through each of them and hang them all together on a hook of a crane, etc., and then
At the same time, the slits 2 are pulled upward to widen the cracks in the slit 2, and the body cloth 1 is pulled out from under the bag cargo, etc., thereby leaving the bag cargo, etc. in its multi-tiered packaging state. , I am now able to unpack.

By the way, in such cargo handling and unloading operations of the transport unit, depending on the degree of hanging of the slinging rope, the horizontal balance of the transport equipment may be lost during cargo handling, and the packing style of the transport unit may also be affected. In this case, since the puller is located at the bottom, the slinging rope passed through the puller during unpacking is hung diagonally on the hook of the crane, which tends to damage the bag cargo.

Such loss of horizontal balance and damage to the bag cargo occur because a lifting hand or a pulling hand is attached to one hook of a crane or the like.

Therefore, the most important thing to prevent such horizontal imbalance and damage to the bag cargo is to avoid hanging the lifting hands and the pulling hands diagonally, so the rigidity of the lifting hands on the hook of a crane etc. Load lifting hooks are hung on the frame at approximately the same intervals as the spacing between the hanging hands in the loading state of the transport unit, and stable transport is achieved by placing the lifting hands or puller hands of the transport unit on each of the load lifting hooks. Capable of handling and unpacking the unit.

However, when such load-hanging hooks are hooked onto the puller of the transport unit to unload the cargo, there is a risk that the hooks may come into direct contact with the packed cargo cargo and damage the cargo bags.

(Purpose of the invention) The present invention was created in view of the above points, and its purpose is to provide a hook for unpacking that can prevent damage to the load caused by the hook when lifting the hook. It is something to do.

(Summary of the invention) The gist of achieving the purpose of the invention is as follows:
The bag cargo, etc., stacked in multiple tiers, is wrapped in a flat rectangular body cloth with a unfolded shape that has a slit for opening the bottom for unpacking, and is transported in bulk as the stacked cargo. The slits are expanded by pulling up the short pulling handles on both sides of the bottom of the body cloth, and the body cloth is pulled out from under the bag cargo, etc., and the bag cargo is removed in its packing form. An unpacking hook that can be hung on the puller of a transport unit that can be unpacked as it is, and a flat plate that comes into contact with bag cargo, etc. of the transport unit on the back of the hook body that can be hung on the puller. is fixed at a substantially right angle, the peripheral edge of the corresponding plate is curved inward at the attachment point of the hook body, and the outer surface of the corresponding plate that comes into contact with bag cargo, etc. is a smooth surface. It's on the hook.

(Embodiments of the invention) The present invention will be described below based on embodiments shown in the drawings.

FIG. 1 shows an embodiment of a hanging device to which a hook for unpacking according to the present invention is applied.

In the figure, reference numeral 8 indicates a rigid frame made of a rigid member, such as a pipe material, and wire ropes 9 are provided at each of its four corners to suspend this frame 8 from a hook of a crane or the like. ing. Since each wire rope 9 has the same length,
The frame body 8 is suspended from a hook of a crane or the like with stable horizontal balance. Further, from the frame body 8,
Four hanging ropes 10 of equal length are suspended, and hooks 11a, 11b, 11c, and 11d for unpacking according to the present invention are provided at the lower ends of the hanging ropes.

By the way, this hanging tool is for hanging a transport unit using a transport tool such as that shown in FIG.
The distance between the handle and the hook 11b is approximately equal to the distance between the pair of handles provided at the ends of the body cloth described above.

In this example, the frame is suspended from a hook of a crane or the like using a wire rope, but the frame is not limited to this, and a chain or the like may also be used. Although the hook is suspended from the frame via a hanging rope, the hook is not limited to this, and a chain or the like may be used.

Furthermore, in this example, one transport unit is lifted by a set of four unpacking hooks, but as shown in FIG. Unraveling hooks 11'a, 11'b, 1
1'c, 11'd and the second set of unpacking hooks 12
Two sets of unpacking hooks a, 12b, 12c, and 12d may be provided.

According to the hanging device having the structure described above, the unpacking hooks are suspended from the frame at approximately the same intervals as the distance between the hangers of the transport unit. By hanging the unloading hook, the horizontal balance of the transport unit will always be maintained stably.Furthermore, cargo handling operations can be carried out simply by hanging the unloading hook on the hanger, making it easy for those familiar with sling work to keep the transport unit stable at all times. This can be done even if you are not a trained worker.

In addition, since the puller handle is located almost directly below the lifting hand of the transport unit, it is possible to pull the puller handle directly upward during unpacking using the unpacking hook of the lifting device. becomes.

Next, the hook for unpacking will be explained based on FIG.

Reference numeral 13 denotes a backing plate made of a rectangular thin steel plate with a smooth surface finish, the inner surface of which is welded to the back side of the hook body 11, and the peripheral edge curved toward the attachment side of the hook body 11. . Reference numeral 14 denotes a loop provided inside the upper end of the backing plate 13, and the loop 14 is passed through the hanging rope 10 connected to the hook body 11 to prevent the backing plate 13 from swinging.

That is, during unpacking work, if the hook body 11 of the unpacking hook is placed on the puller of the transport unit and the backing plate 13 is aligned with the bag cargo side, the plate 13 will be warped. , patch plate 1
3 moves up and down smoothly together with the hook body 11 without getting caught in the bag cargo. Therefore, the hook body 11 does not come into direct contact with the bag cargo, so that damage to the bag cargo can be prevented.

In the explanation of each embodiment, the conveyance device shown in FIG. 4 was explained, but the present invention is not limited to this. It is also possible to lift up a conveyor or the like sewn into a shape.

(Effects of the invention) As described above, according to the invention, when used as a sling, etc. that can perform stable cargo handling operations of a transport unit instead of transporting bag cargo, etc. using pallets, the hook body can be directly attached to the bag by the backing plate. In addition, since the patch plate is flat and has a smooth outer surface, the patch plate slides smoothly against the bag cargo, etc., and unpacking operations can be performed without damaging the bag cargo, etc. It has the excellent advantage of being very easy to use, and its usability is great.
