Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an unloading platform, and more specifically, the present invention relates to an unloading platform for unloading bag cargo, etc., which is used as an auxiliary tool for bulk transport of multiple bag cargo, etc. The present invention relates to a loading platform that allows unloading onto a pallet or the like without the load collapsing.

Conventionally, in order to transport bag cargo filled with cement, fertilizer, etc., the bag cargo is piled up in multiple tiers on a pallet without falling apart, and then transported along with the pallet to a truck or ship. It is common to use bulk transportation, in which the bags are loaded onto a container such as a container, and then unloaded along with the pallets at the destination. That is, the pallets are used as an auxiliary tool for bulk transportation, and the used pallets are usually collected and reused after transportation.

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, it takes time and money to collect them, and shipping costs. However, there was a problem in that the product loading efficiency was considerably reduced.

In order to solve these difficulties, a sheet-type conveying device has recently been proposed as an auxiliary device for bulk conveying multiple bags of cargo, etc. in place of the above-mentioned pallets.

FIG. 1 shows an example of such a carrier, and the figure shows its unfolded state.

In the figure, reference numeral 1 indicates a rectangular body cloth made of a resin sheet or synthetic fiber sheet that is slippery and strong, such as polypropylene or polyethylene, and 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 a tensile force is applied to the puller 5 to widen the tear in the slit 2, a uniform force is applied to the central portion of the body cloth 1 on which the bag cargo or the like is placed.

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.

According to the conveyance sheet body configured as described above, the bag cargo and the like are stacked in multiple stages at the center of the body cloth 1 and packed by the body cloth 1. (Hereinafter, a unit of transport in which a large number of bag cargoes are packed together using such a transport sheet will be referred to as a transport unit). When handling cargo, a hook of a crane or the like is hung on the hanging hand 3 to load it onto a ship, etc. When unloading, the transport unit is placed on a pallet and the pulling hand 5 is pulled upward. At the same time, the gap in the slit 2 is widened, the trunk cloth 1 is pulled out from under the bag cargo, and the bag cargo can be placed on the pallet in its multi-tiered packaging state. It's summery.

By the way, the present inventors previously developed an unloading platform as shown in FIG. 2 as a means for orderly placing the bag cargo on the pallet when unpacking such a transport unit. Proposed.

As shown in FIG. 2, this unloading table includes, for example, a type on which two of the above-mentioned transport units can be placed at the same time. Pallet mounting surface 1 on which pallets 9 are placed upright and pallets are placed on the left and right sides thereof, respectively.
0 and 11 are provided, and a pair of guide members 12 are erected on both sides of each pallet placement surface adjacent to the partition wall 9, and furthermore, a pair of guide members 12 are provided on both sides of each pallet placement surface adjacent to the partition wall 9. It has a structure in which an opening 13 for taking out the pallet is provided on the end side, and 2
The individual transport units that are lowered at the same time are
The partition wall 9 separates the left and right pallet mounting surfaces 1.
The pallets 1 prepared in advance on the pallet mounting surfaces 10 and 11 are sorted into pallets 0 and 11 and guided by the partition wall 9 and the guide member 12.
4.

The bag cargo unpacked onto the pallet 14 is then transported together with the pallet to a warehouse or the like by a forklift that enters from the open portion 13 side.

By the way, when unloading using such an unloading platform on a quay, the unloading platform 15 and The crane truck 16 for lifting loads must be arranged as shown in FIG.

However, according to this arrangement, since the forklift approaches in opposite directions, the forklift must approach one side with its back to the quay, and the driver must be careful to avoid falling. There was also the problem that there were many curved roads, making steering operation complicated.

The present inventor conducted various studies on the above-mentioned unloading platform with the aim of solving such problems, and as a result, he came to discover the following findings.

That is, the reason why such an inconvenience arises due to the arrangement is considered to be due to the fact that the openings for carrying out the pallets are provided facing each other.

From this, if an opening for pallet removal is provided so that the pallets placed on each pallet placement surface can be taken out from the same direction, the pallets on the pallet placement surface can be taken out safely and efficiently. The present invention was developed by paying attention to the fact that it is possible to do this.

The gist of the present invention is that a partition wall for sorting loads is erected perpendicularly to a pair of opposing sides of a rigid stand main body formed in a planar rectangular shape, and that the partition wall is Two pallet placement surfaces are formed on the left and right on which pallets are placed in advance, and at least one side of each of the pallet placement surfaces adjacent to the partition wall is open, and each pallet placement surface adjacent to the partition wall is A rectangular guide member whose tip expands outward is arranged to stand on the other side of the surface and/or at the center of the end side of each pallet placement surface facing the partition wall. It is located at the unloading platform.

The present invention will be explained below based on the embodiment shown in FIGS. 4 and 5.

FIG. 4 shows an embodiment of the unloading platform according to the present invention. In the figure, reference numeral 20 denotes a rigid stand body in which steel plates 22 are attached to both the front and back sides of a rectangular frame body 21 formed of steel material, and a partition wall 23 is erected in the center of this stand body 20. Well, this partition wall 2
The first pallet mounting surface 2 is placed on the left and right stand bodies 20 of 3.
4 and a second pallet mounting surface 25 are formed. Note that the size of this pallet mounting surface is preferably determined according to the specifications of the pallet. This partition wall 23 is for distributing the two conveyance tools suspended at the same time to the pallets 26 prepared in advance on the first and second pallet mounting surfaces, and allows for smooth distribution of the conveyance units. In this example, a pipe 27 is welded to the tip of the partition wall 23 along its longitudinal direction.
Further, the partition wall 23 has a height that allows pallets to be stacked in three stages, so that unpacking operations can be performed continuously. Reference numeral 28 indicates a rectangular guide member with an outwardly curved tip;
8 are erected at the center of the edge of the first pallet mounting surface 24 and the edge of the second pallet mounting surface 25 facing the partition wall 23, respectively. Here, the reason why the tip of the guide member 28 is curved outward is as follows.
This is to allow the conveying unit to be placed at a predetermined position on the pallet 26 by the curved tip even if the conveying unit is not suspended from directly above the pallet placement surface.

In this example, the guide member 28 is formed into a roller conveyor structure in which a large number of rollers 29 are arranged vertically in parallel to facilitate guiding of the conveying unit. Furthermore, some conveyors, such as the conveyor sheet body shown in FIG. In the example, the width of the guide member 28 is made slightly narrower than the separation distance of the extractor 5.

30 is the first and second pallet mounting surface 2
In this example, both sides of the pallet mounting surface adjacent to the partition wall 23 are used as openings 30 for taking out the pallets placed on the pallets 4 and 25.

According to the unloading platform having the structure described above, the conveyance unit is lowered to a predetermined position of the pallet placed on the pallet placement surface, and the conveyance sheet body is moved to the bottom of the bag cargo by a predetermined operation. When the bag is removed from the pallet, the bag cargo remains unpacked on the pallet. Furthermore, since the first and second pallet loading surfaces are provided with openings for taking out the pallets on the same side, the pallets can be taken out by a forklift from the same direction of the platform body. It has become possible to carry out the removal work safely and efficiently.

Further, by arbitrarily selecting the heights of the partition wall and the guide member, it becomes possible to unpack the pallets continuously by placing several stages of pallets on each pallet placement surface.

In this example, the guide member has a roller conveyor structure, but it is not limited to this, and may be in the form of a flat plate.In short, any guide member that can smoothly guide the conveyance unit may be used. Bye.

In addition, in this example, the base body is made of steel to have a box-like rigid structure, but the structure is not limited to this, and wood, aluminum, etc. may also be used. It is not necessary to provide

Furthermore, although the partition wall is made high in this example, it is not limited to this, and may be as high as the transport unit, in which case the transport equipment is first distributed to the left and right. It is preferable that the height of the partition wall is slightly higher than the height of the guide member.

FIG. 5 shows another embodiment of the present invention, and this embodiment is different from the embodiment shown in FIG. The guide member 28 is provided only on one side of the surface, and is attached to the other side of the pallet placement surface adjacent to the partition wall and to the edge of the pallet placement surface facing the partition wall 23.

According to this embodiment, the transport unit has an opening 3
Pallet 2 is supported and guided on three sides except 0.
6 to the predetermined position becomes easy.

FIG. 6 shows a modification of the embodiment shown in FIG.

A guide member 28 is provided on the unloading platform shown in FIG.
are provided on the other side of the pallet placement surface adjacent to the partition wall 23 and on the edge of the pallet placement surface facing the partition wall 23; however, in this example, other than the pallet placement surface adjacent to the partition wall 23 The feature is that the guide members 28 are attached only to the sides. In this example,
Since the open portion 30 and the end side facing the partition wall 23 are open, it is easy to place the pallet on the pallet placement surface and take out the pallet, thereby improving work efficiency.

As described above, according to the present invention, pallets can be carried out from one direction, which not only makes it possible to efficiently operate a forklift for carrying out pallets, but also allows the installation location of the unloading platform to be changed. Even if it is a quay, there is no pallet unloading side on the quay side, so pallet unloading work can be carried out safely, and its usability is great.
