Description

[Detailed description of the invention]

In the invention, when articles stacked on a pallet are sequentially placed and carried out by a carry-out conveyor that advances and retreats at a predetermined position, the articles are constantly suppressed in a flat state by 1 m, and the level of the article position is detected. , related to article suppression and level detection 1i5111 in an 11 degree article dismantling machine that enables reliable and rapid dismantling of articles in a stacked state CIA
Ru. Conventionally, a pallet loaded with stacked articles is raised to a predetermined height using an elevator, and then the articles on the top tier are placed on the carry-out conveyor by 1% of the advance of the carry-out conveyor.
The retraction of the unloading conveyor is carried out to a predetermined location, and the advancing and reversing of the unloading conveyor and the intermittent raising and lowering of the elevator (: The articles in the stacked state are gradually disassembled, but in this case, the articles are especially Flexible packaging, such as fertilizer bags, sandbags, cement bags, sand bags, etc., has unevenness on the left and right sides, so it may be slightly deformed when the delivery conveyor moves forward or backward. It is also necessary to check whether the position of the article to be placed is appropriate for the set position of the unloading conveyor. Therefore, when placing the item on the unloading conveyor, Workers must detect the deformation of the item and the appropriateness of the placement of the item each time, but when handling a large number of items in such work, it is inevitable that efficiency will be reduced due to factors beyond the mind and body. 52, there is a danger that there is a risk of disasters occurring due to the collapse of goods. Therefore, this invention is designed to avoid reducing work efficiency and causing unforeseen accidents to workers as described above.
Detection of pressure and level of articles in a laminated article dismantling machine capable of dismantling articles in a stacked state at a predetermined height I: 11L, II layered on a reciprocating carry-out conveyor #Mi
A stacked article dismantling machine that sequentially disassembles stacked articles by loading and unloading the stacked articles by reciprocating movement of the carrying-out conveyor. The top surface of the article is pressed and flattened with the suppressed plate, and the one foggy article is placed on the carry-out conveyor and carried out by the suppressing plate and the detector on the stand side placed close to the suppressing plate. The feature is that the level can be detected automatically.
