Abstract

PURPOSE:To correctly nip a transport object article by the claw parts by constituting the title device so that one claw part approaches the transport object article, in the state where the other claw part is engaged with the transport object article when one claw part contacts the transport object article in precedence to the other claw part. CONSTITUTION:Claw parts 18 and 19 are positioned on the both sides of the lattice crosspiece of a grid spacer 1, and the claw parts 18 and 19 are approached each other by contracting a claw part driving cylinder device 20, and the grid spacer 1 is nipped between the claw parts 18 and 19. In this case, if one claw part 18 contacts the lattice crosspiece of the grid spacer 1, in precedence to the other claw part 19, the crosspiece 19 approaches the grid spacer 1, in the state where the claw part 18 is engaged with the lattice crosspiece. Therefore, even if the grid spacer 1 is placed, separating from a prescribed position, the claw parts 18 and 19 are allowed to automatically correspond to the lattice crosspiece, and the lattice crosspiece of the grid spacer 1 can be nipped surely by these claw parts 18 and 19.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an article delivery device for holding and taking out grid spacers and the like in a lattice shape.

BACKGROUND OF THE INVENTION Conventionally, during the manufacturing process, exterior building materials are subjected to an autoclave (high-temperature, high-pressure steam curing) process while placed on grid spacers in the form of lattice plates. Then, at the end of the autoclave process, the grid spacer is collected and reintroduced into the manufacturing process. However, because grid spacers are shaped like lattice plates and are at high temperatures when collected, they cannot be removed by suction equipment or by hand. Conventionally, grid spacers were transported by clamping the lattice bars of the grid spacers using clamping equipment. .

Problem to be Solved by the Invention However, as described above, when the lattice bars of the grid spacer are clamped by the clamp device, the grid spacers are not necessarily placed in the same position, so it is difficult to automatically move the lattice bars of the grid spacer. Moreover, it is difficult to clamp the grid spacer accurately, and in some cases, there is a problem that the clamping device must be attached to the grid spacer manually.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an article unloading device that can automatically and accurately clamp articles such as grid spacers.

Means for Solving the Problems In order to solve the above problems, the present invention provides a traveling cart that is driven to travel between a take-out position and a destination position for articles to be carried out, and a carriage that is provided on the traveling carriage and is equipped with an elevating pedestal that is driven up and down between a position close to and a position away from the target article; a pair of claws provided on the elevating pedestal so as to be movable in the horizontal direction and gripping the object to be carried out; A claw driving cylinder device which is fixedly held and in which a rod part connected and fixed to the other claw moves in and out in a horizontal direction to move the claws toward and away from each other; The structure includes a stopper portion that locks at a predetermined position.

Operation: With the dual structure, the traveling carriage is driven to the removal position of the article to be carried out, and the movable base is positioned above the article to be carried out. Then, the elevating pedestal is lowered to a position close to the article to be carried out, and the claw portions are positioned on both sides of the article to be carried out. In this state, the claw drive cylinder device is contracted to bring the claws closer together, and the article to be carried out is held between the claws. At this time, if one of the claws comes into contact with the object to be carried out before the other claw, one of the claws is locked to the object to be carried out and the other claw touches the object to be carried out. To approach an article and automatically handle and accurately hold the article to be carried out. Then, with the elevating pedestal raised and held at the separated position, the traveling cart is driven to travel to the destination position, the elevating pedestal is lowered, and the claw drive cylinder device is extended to separate the claws from each other. The item to be transported is placed in a predetermined position. At this time, the claw parts are separated from each other until they come into contact with the stopper part, and return to the initial state.
