Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an unloading platform, and more particularly, the present invention relates to an unloading platform for unloading bag cargo, etc., which is transported by a sheet-type conveyor as an auxiliary device for bulk conveyance of multiple bag cargo, etc. The present invention relates to an unloading platform that allows unloading onto a pallet or the like without touching the surgical site while still being packed.

Conventionally, in order to transport bag cargo filled with cement, fertilizer, etc., the bag cargo was stacked in multiple tiers on a pallet without shifting, and the bag cargo was bundled into a J.
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. In other words, the pallet is used as an auxiliary tool for bulk transportation, and the used pallet is usually collected and reused after transportation.

However, when transporting a large amount of bag cargo, etc., a large number of the above-mentioned nozo reds are required, and since the pallets themselves are bulky and heavy, collecting them requires a lot of effort, expense, and There was a drawback that the product loading efficiency during shipping was considerably reduced.

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

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

In the figure, 1 is a resin sheet that is slippery and strong.

A rectangular body cloth made of a synthetic fiber sheet, such as polypropylene or polyethylene, is shown, 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 nine hanging hands 3 are provided at each end of the trunk cloth l is because ``during cargo handling, a hook of a crane or the like is hung on each toothed hand 3 for four-point suspension.
This is to obtain horizontal balance for the bag cargo stacked in multiple tiers.

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. Incidentally, the interval between the pair of reference lines 40 is determined in accordance with a commercially available standard such as 9lets.

Slightly inside the pair of reference lines 4, the slit 2 has a puller 5 which is used to widen the eyes of the body cloth.
It is sewn to the body cloth 1 so as to protrude from both ends of the body.

The pull-out handle 5 is formed by stitching the same belt-like sheet as the body cloth 1 or a sheet 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 cracks in the slit 2, a uniform force is applied to the center portion of the body cloth 1 on which the bag cargo, etc. is placed. .

Reference numeral 6 indicates a tie string provided on one end side of the trunk cloth l so as to sandwich the slit 2, and when packing the bag cargo,
This knot string 6 is attached to the knot ring 7 provided opposite the other end of the body cloth l.
The bags are tied together to pack the cargo.

According to the conveyance sheet body configured as described above, the bag cargo etc. are stacked in multiple stages in the central part of the trunk cloth 1,
It is designed to be packed using a trunk cloth. and,
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 sheet body is placed on a pallet and the pulling hand 5 is pulled upward. However, the opening of the slit 2 is widened, the trunk cloth 1 is pulled out from under the bag cargo, and the bag cargo is placed on the top of the bag in its multi-tiered packaging state. is now possible.

However, if the loading position of the conveyor sheet on the pallet shifts during unpacking, the load may collapse if too much force is applied, and even if the load does not shift on the pallet, the load may be unloaded. Since the bag cargo is placed on the pallet in a state that protrudes from the pallet, even if the bag is stored in an automated rack warehouse, even if the deviation is small enough not to cause the surgical site to shift. The pallet was detected by a pallet detector and had to be reloaded.

In this case, the reason why the loading position of the conveyor sheet body shifts is because the conveyor sheet body was being lowered from above the pallet by a crane, etc., while the operator was adjusting the loading position. . And this adjustment work is
It was not always possible to place the device properly by hand, and it required a great deal of labor or time by the worker to fix it.

Therefore, in order to prevent this kind of displacement of the mounting position,
When the conveyance sheet body is lowered, above the pallet,
Since it is only necessary to guide the conveyance sheet body to a predetermined placement position, the present inventor proposed that by erecting a guide member opposite to one side of the stand main body having a pallet placement surface. The present invention was developed by focusing on the ability to guide a conveyance sheet body to a predetermined placement position on a pallet.

The gist of the present invention is to include a rigid stand main body having a pallet placement surface, and guide members erected at central portions of opposing side ends of the pallet placement surface, The distal end portions of the pair of guide members are located on the unloading platform, which is characterized by expanding outward from each other.

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