Description

TECHNICAL FIELD The present invention relates to a joint alignment positioning device for cutting a plate material in accordance with a so-called joint having a shallow groove formed on the surface of the plate material.

[Conventional technology]

When a board material (building material) such as cement board or calcium silicate board is used as an exterior, a so-called "joint" such as a brick pattern or a grid pattern is provided with a shallow groove on the surface, but the area of the wall of the building to be attached, It must be cut to size according to the shape. The recent construction method is to cut and process a large amount at the same time in a factory based on a unified standard rather than to match dimensions on site and cut, or to cut and assemble to the required dimensions in advance at the factory to suit each individual building. There are many rational construction methods such as work and finishing work. Conventionally, when cutting such a plate material in accordance with a certain joint, it is general to apply a ruler to provide a cutting mark, or to irradiate a laser beam along a cutting line and run a running saw to perform cutting.

[Problems to be Solved by the Invention]

A certain degree of skill is required in both cases of applying a ruler to make a mark and cutting and irradiating with a laser beam for cutting. Further, the work of cutting the joint with the joint is labor-intensive, and it is difficult to increase the work efficiency, and it is troublesome when the working dimensions are various.

The present invention has been made in view of these problems, and an object thereof is a plate material capable of efficiently and automatically cutting the plate material in accordance with various dimensions based on the joint formed on the surface of the plate material. The object of the present invention is to provide a positioning device for joint alignment.

[Means for Solving the Problems]

That is, in order to solve the above-described problems, the present invention provides a positioning device for jointing plates, which includes a lateral movement mechanism and a ruler for abutting the ends of the plate, and a lateral pushing cylinder for abutting the plate on the ruler. And a proximity sensor having a lateral movement mechanism for gripping an end portion on the plate material side, and a proximity sensor having an up-and-down movement mechanism for dropping the dock into a groove of a joint of the plate material and lifting the dock to detect the joint. A guide equipped with a lateral movement mechanism and a base mounted with a sensor that can be moved and fixed in the vertical direction (material feeding direction), a limit switch that detects when a plate material has abutted against the ruler, and movement of the ruler. An auto switch for detecting the completion of the operation, an auto switch for detecting the completion of the operation of the horizontal push cylinder, a photoelectric switch for detecting the front end portion of the plate material, and a vertical movement mechanism are provided. A plurality of clamps for gripping the mounting and plate rear end part and a photoelectric switch for detecting the rear end portion of a vertical press unit for Okuzai the plate material in the longitudinal direction, characterized in that it further consists.

[Work]

The operation when the positioning device for aligning the joints of the plate members is used as the above means will be described below with reference to the reference numerals in the accompanying drawings.

The sensor mounting base 60 is manually slid by the brick pattern of the joint groove (vertical groove M, horizontal groove N) (Fig. 8,
FIG. 9) FIG. 13 for setting the positions of the proximity sensors S2 to S5).

The guide 14 equipped with the sensors S2 to S5 is moved and positioned. That is, as shown in FIG. 14, the position (distance Z) of the proximity sensor S2 or the like with respect to the vertical saw 6 is determined (determination of the cutting position with respect to the vertical groove M of the joint). these,
The operation of is operated before the cutting pattern is changed.

The plate material W is placed at a predetermined position on the material feeding surface 2 (see FIG. 1).
The lateral pushing cylinder 10 pushes the plate material W in the directions of the rulers 4 and 5. When the limit switch L1 that comes into contact with the rulers 4 and 5 of the plate material W is actuated, the vertical pushing metal fitting 19 of the vertical pushing device moves forward by rapid feed and pushes the plate material W, and the photoelectric switch P1 detects the front end portion of the plate material W. It will be delayed. When the photoelectric switch P2 detects the front end portion of the plate material W, the plate material W sent by the slow feed stops. The plate material W is stopped, and a few seconds later, the vertical pressing metal fitting 19 of the vertical pressing device advances the plate material W again by slow-feeding.
The plate material W is stopped by the vertical pressing metal fitting 19 of the vertical pressing device when the plate material W advances and the proximity sensor S1 detects the lateral groove N. When the lateral groove N is detected and the plate material W is stopped, the clamp vise 11 holds the plate material W. When the gripping of the plate material W by the clamp vice 11 is completed, the horizontal pushing cylinder 10 returns to the original position, the rulers 4 and 5 are separated from the plate material W, the proximity sensor S1 returns to the original position (upward), and the vertical pushing device The vertical push fitting 19 moves backward and returns to the original position. Side push cylinder 10,
When the operations of the rulers 4 and 5, the proximity sensor S1 and the like are completed, the auto switches L2 and L3 are respectively actuated to output a completion signal. The clamp vise 11 moves rearward while gripping the plate material W, detects the vertical groove M of the joint by the proximity sensors S2 to S5, and stops when the position of the vertical groove M is detected.

The clamp vise 9 for material feeding advances, and the photoelectric switch P3 attached to one of the clamp vise 9 (see FIG. 1).
Detects the rear end portion of the plate material W, these clamp vices 9 are stopped, and the rear ends of the plate material W are gripped together. After the clamp vise 9 grips the plate material W, the clamp vise 11 releases the plate material W, and at the same time, the proximity sensors S2 to S5 also return to their original positions. (The guide 14 retracts). The plate material W is cut into a required size by the vertical saw 6, and further, the plate material W is cut in accordance with the vertical joint M, and then laterally cut into a required size by the horizontal saw 101.
