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 transported by a sheet-type transport device as an auxiliary tool for bulk transport of multi-bag cargo, etc. The present invention relates to an unloading 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 a bulk transport system in which the bag cargo is loaded onto a container, etc., and then unloaded along with the pallet 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 slippery yet strong resin sheet or synthetic fiber sheet, 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 both ends of the body cloth 1 so as to sandwich the slit 2 therebetween, 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. A circular band is sewn to the back side of the body cloth 1 so that the entire weight of the bag cargo is uniformly applied to the body 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, and the bag cargo, etc. is placed within this reference line 4. The spacing between the lines 4 is determined according to the standards of commercially available pallets. Slightly inside the pair of reference lines 4, pull-out hands 5 for diffusing 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 diffuse the tear in the slit 2, a uniform force is applied to the center 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 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). (The positional unit of transport in which a large number of bag cargoes are packed together using a transport sheet is called a transport unit.) When handling cargo, a hook of a crane or the like is hung on the lifting 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. However, by widening the tear in the slit 2, the body cloth 1 can be pulled out from under the bag cargo, and the bag cargo can be placed on the pallet in its multi-tiered packaging state. ing.

However, if the loading position of the transport unit on the pallet shifts during unpacking, the load may collapse in extreme cases, and even if the load does not shift, the unpacked bag cargo may be larger than the pallet. Since the pallet is placed on the pallet in a protruding state, if it is stored as is in an automatic rack warehouse, even if the pallet is misaligned to the extent that it will not cause the load to collapse, it will be detected by the pallet position detector. I had to make some reloading adjustments.

In this case, the reason why the loading position of the conveying unit is shifted is because the loading position is adjusted by the operator while the conveying unit is being lowered from above the pallet by a crane or the like.
In this adjustment work, it is not always possible to place the device properly by hand, and fixing the device requires a great deal of labor or time by the operator.

Therefore, in order to prevent such displacement of the loading position, when the transport unit is lowered,
Since it is only necessary to guide the conveyance unit to a predetermined placement position above the pallet, the present inventor installed a guide member upright facing one side of the stand main body having the pallet placement surface. The present invention was developed based on the fact that the transport unit can be guided to a predetermined placement position on the pallet.

The gist of the present invention is to provide a rigid table main body formed in a planar rectangular shape, and a rigid table main body that is erected along the width direction of the rigid table main body, and that the rigid table main body is placed on two pallet mounting surfaces. It is provided with a partition wall for sorting loads and a guide member erected at the center of one opposite end of each of the pallet mounting surfaces, and the tips of each pair of guide members expand outward from each other. It is located at the unloading platform, which is characterized by being open.

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 2 shows an embodiment of the unloading table according to the invention.

In the figure, 20 is a rectangular frame 1 made of steel.
The figure shows a rigid stand main body formed by fixedly connecting two box-shaped rigid stands 10 in parallel, each having a steel plate 12 attached to both the front and back sides of the main body, and a partition wall 21 in the center along the width direction. A first pallet mounting surface 22 and a second pallet mounting surface 23 are formed on the left and right sides of which are erected and on which pallets 13 are respectively placed. The sizes of the first pallet mounting surface 22 and the second pallet mounting surface 23 are preferably determined in accordance with the pallet specifications. This partition wall 21 is 2
Conveyance units 1 suspended in parallel at the same time
6 to the pallets 13 on the first and second pallet mounting surfaces on the table main body 20. In this example, in order to achieve smooth distribution of the conveying units 16, the tip of the partition wall 21 is A pipe 24 is welded along its longitudinal direction.
Reference numeral 14 indicates an opening for a forklift claw provided in the left and right frame members 11a and 11b of the frame 11 in FIG. The table can now be moved. Reference numeral 15 indicates a guide member which is erected upward from the center of the frame member 11c, 11d in the vertical direction in FIG. Therefore, when the conveyance unit 16 is placed on the pallet 13 on the platform body 10 by a crane or the like, even if the conveyance unit 16 is not located directly above the pallet 13, the outside of the guide member 15 It is placed in a predetermined position on the pallet 13 by being guided by the curved tip.

The pallets 13 are carried in and out from the open side of the platform body 20 on which the guide members 13 are not provided.

In this example, the guide member 15 is formed into a roller conveyor structure in which rollers 17 are arranged in parallel so as to be rotatable in upward and downward directions in order to facilitate the guidance of the conveying unit. Furthermore, some conveyance devices, such as the conveyance sheet body shown in FIG. In the example, the width of the guide member 15 is made slightly smaller than the separation distance of the extractor 5. Furthermore, it is preferable that the placement positions of the two conveyors suspended at the same time be corrected by the guide member 15 after they have been sorted by the partition wall 21.
In this example, the partition wall 21 is made slightly higher than the guide member 15.

According to the unloading platform having the above-described structure, when two transport units packed with bag cargo, etc. are placed on each pallet on the unloading board at the same time, the transport units are placed at the predetermined loading position of the pallet. Even if it descends with a slight deviation, it is corrected by the guide member and guided to the predetermined loading position, so after removing this conveyance sheet body by the predetermined operation described above, the unpacked cargo is placed on the pallet. For example, bag cargo can be stored in a warehouse or the like without protruding from the pallet while stacked in multiple tiers.

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 formed of steel into a box-like rigid structure, but it is not limited to this, and may be made of wood, aluminum, etc. It is not necessary to provide a steel plate.

Furthermore, in this example, the stand main body has a connected structure, but the stand body is not limited to this, and a partition wall may be erected along the width direction of the stand main body of an integral rigid structure at the center. .

Next, the cargo handling and unloading work process using the unloading table according to this embodiment will be explained based on FIG. 3.

In the figure, a transport unit 16 in which bag cargo is stacked in multiple stages and packed is transported to a destination quay by a ship 25, and a hanging device 27 installed on a crane 26
You can lift two items at the same time. On the other hand, on the unloading stand placed on the land side, pallets 13 are placed on first and second pallet placement surfaces 22 and 23, respectively.
The transport unit 16 is suspended from above this unloading table, and each pallet 11 is
be distributed to. Then, the transport unit 16 is guided and placed on the pallet 13 at a predetermined position by the guide member 15. Furthermore, in order to unpack the cargo, each hook of the hanging device 27 is attached to the transport unit 16.
Hang it on the puller 5 and pull it upward.
At this time, since the puller 5 is located outside the guide member 15, smooth pulling is possible.
When the conveyance sheet body of the conveyance unit 16 is removed, the bag cargo is placed on the pallet 13 in the form of a multi-stage stack. Then, the pallet 13 is carried out by a forklift or the like from the open side of the table main body where the guide member is not erected, and stored in a warehouse or the like.

As described above, according to the present invention, two loads can be separated by a partition wall and placed on predetermined positions on a pallet, so the loads can be quickly transported to a warehouse or the like without interfering with cargo handling operations. In particular, when a large number of bag cargoes are packed together using a conveyor such as a conveyor sheet with an expanding bottom, the cargo can be stored without any damage to the bag cargo and the pallet. It can be solved and its usability is great.
