Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tile stacking device for gripping and moving a large number of bound tiles (Japanese type, S type, flat type, etc.).

[0002]

[Prior Art]

 Conventionally, when stacking roof tiles on the roof of a house, a transportation mechanism such as a ladder-shaped lifting device is installed between the ground and the roof, and a large number of workers placed on a pallet on the ground by workers. 10 to 15 pieces of the stiles were placed on the transport mechanism at a time, transported on the roof, and moved to a predetermined position by a worker on the roof to stack them.

[0003]

[Problems to be solved by the device]

 Conventionally, as mentioned above, since a carrying mechanism such as a ladder-like lifting device is used, workers are required both on the ground and on the roof, and each worker needs to move 10 to 15 stiles. However, there is a problem that the burden on each worker is large.

In addition, when the roof area is large, it is necessary to make two or more workers resident on the roof and move the roof tiles transported to the roof to a predetermined position to stack them, and also to transport the transportation mechanism itself. A method of transporting the roof to a predetermined position on the roof by moving it along the road has been used, but since it is necessary to move the roof tiles on the pallet on the ground and transport it to the transport mechanism by the worker, The problem was to be forced to increase.

Further, in this type of transport mechanism, it is structurally impossible to move and stack about 50 stiles on the roof at a time, and there is a problem that work efficiency is not good.

[0006] Further, since it is necessary to work on the roof even if the transport mechanism is used, it has been a problem that workers on the roof are dangerous.

[0007] In view of such drawbacks, the present invention reliably reduces the number of personnel when stacking a plurality of roof tiles on the roof by securely gripping a large number of roof tiles at once by the weight of the roof tiles. It is intended to provide a tile stacking device capable of performing work.

[0008]

[Means for Solving the Problems]

 According to the present invention, a pair of main shafts are arranged in parallel vertically, and a pair of upper support arms are rotatably attached to both ends of the upper main shaft in the longitudinal direction, and both ends of the lower main shaft in the longitudinal direction. A pair of lower support arms are rotatably attached to each other in a crossed manner, the upper end of the lower support arm is rotatably attached to the lower end of the upper support arm, and the main shaft is attached to the lower end of each lower support arm. Grips are provided along the length of the lower spindle, and the lower spindle support piece has an opening with an opening for the lower spindle and a clamp at the middle of the upper spindle in the longitudinal direction. The main shaft is penetrated so as to be orthogonal to each main shaft, and is rotatably provided with the upper main shaft.

[0009]

[Action]

 The operation of the present invention will be described.

When gripping a large number of bound tiles using the tile stacking device according to the present invention, first, the tile stacking device is attached to a carrying device such as a crane.

Next, the lower spindle is positioned at the opening of the opening of the lower spindle support piece to open the gap between the grips (between the grips on the left and right sides in FIG. 1) (see FIGS. 3 and 6). .. At this time, the lower spindle support piece is manually or mechanically rotated about the upper spindle as a fulcrum to position the lower spindle to the open portion of the opening of the lower spindle support piece.

Next, a tile stacking device with both gripping portions open is positioned directly above the plurality of bundling tiles, and the conveying device is moved to a position where the gripping portions come into contact with notches on both sides in the width direction of the girder. Gradually lower through.

Next, the lower spindle is positioned at the sandwiching portion of the opening of the lower spindle support piece so that the two gripping portions are clamped to grip a large number of bound ridges (see FIGS. 4 and 7). At this time, the lower spindle support piece is manually or mechanically rotated about the upper spindle as a fulcrum to position the lower spindle at the nipping portion of the opening of the lower spindle support piece.

Next, the tiles can be stacked by moving the tile stacking device to a predetermined position while holding a large number of bundled tiles, and releasing the grip of the tiles. At this time, since the tile stacking device is moved by the carrying device, the cross tiles can be easily stacked at a predetermined position on the roof.
