Abstract

PURPOSE:To perform stable loading and improve its safety, by flatly pressing the upper surface of goods with a pressor after transferring the goods to a pallet from a load bed, whose lowering level is detectively controlled, when the closely collected soft goods conveyed through a conveyer are loaded to the pallet. CONSTITUTION:If goods g1-g3 on a conveyer 1 come to a prescribed position, a transfer piece 5 moves in the direction of an arrow head to transfer the goods g1-g3 onto a conveyer belt V. Then the transfer piece 5 and a load bed H are retracted in the respective direction. And then the belt V is moved in a direction X1 and the goods g1 are stopped immediately above an arranged pallet 33. Therefore, the belt V is moved running in a direction X2 and the goods g1 are dropped on the pallet 33. Then the load bed H advances to receive the next goods g2 and retracts again. Here a pressor P lowers to flatly press the goods g1 on the pallet 33 and then loads the next stage goods g2. By this repetition, the goods are stably loaded, and safety is improved then collapse of a load can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention is a system for loading cargo, particularly flexible cargo in a densely packed state, transported by a conveyor, in a stacked state, onto pallets that have been kept waiting at a predetermined position in advance. 12% Press from above each time you load I: 1. Make the top surface of the cargo uniformly flat and stabilize the cargo to be loaded from a certain position 1:
It is related to a device for loading and pressing cargo onto pallets that can prevent cargo from collapsing. Conventionally, this device is used to load and press cargo onto pallets and to prevent unforeseen cargo collapse. Desired position @1: When loading transported cargo in a stacked state onto pallets that are waiting at a predetermined position, in the case of rigid cargo, there is no problem, but sand% fertilizer, cement , So-called flexible 1. which stores goods such as grains. In the case of cargo that is

Normally, the top surface of the cargo is pressed down with a suppressor to make it flat, and then the cargo is stacked from below. It doesn't necessarily work, but it depends on the pressing force being too much or too little.6
11. There may be cases where uneven parts of the cargo remain, or the top surface of the cargo is damaged by the suppressor f2, and there is no possibility that the stored items may leak out.11. Furthermore, when pallet F2 cargo is dropped and loaded, the cargo is irregular due to the difference in the falling distance (: If it falls and is severe, there is a risk that L2 may fall to the floor, and the condition of the Gram layer is disordered. Therefore, this invention has developed a pallet system that allows cargo to be kept at a predetermined position in advance, not only for rigid objects but also for flexible cargo, by always dropping the cargo onto the original pallet side at a fixed falling distance. Drop it while maintaining the same condition as when it was transported.

Next, the upper surface of the cargo on the pallet side is pressed down with a suppressor to make it flat, and the cargo is transferred to the pallet side in a stable state at all times and is intended to prevent the cargo from collapsing unexpectedly. This is intended to provide a conveyance/suppressing device for pallets, and the loading frame is movable back and forth (C: 1: 1) on the lifting frame that can be raised and lowered freely on the lifting post. A pusher equipped with a sensor can be moved up and down.

In addition, the cargo conveyance belt is attached so that it can freely run forward and backward, and the belt on the cargo conveyance belt is attached to the pallet waiting at a predetermined position via the elevating restraint frame whose descending level is detected by the level detection sensor. The present invention is characterized in that the cargo is dropped and transferred, and then the presser is used to suppress and flatten the top surface of the cargo on the pallet.An embodiment of the present invention will be described below with reference to the drawings. :, of the pair of pillars fixed and standing upright on the floor plate f, one pair of pillars is not visible in Figure 1) a, a Upper end +: %
