Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to improvement of a fluid pressure supply device.

(Prior Art) Conventionally, for example, there is a door trim of a vehicle such as an automobile in which a surface of a base material is laminated with a synthetic resin skin material. To manufacture this door trim, first, the skin material is clamped by a clamper provided on the moving body, and the moving body is moved into a heating furnace to impart flexibility to the skin material. Next, the moving body is moved to a vacuum forming device, and the above-mentioned skin material having flexibility is integrally attached to the surface of the base material. After that, the unclamper is operated to unclamp the skin material, and then the movable body is returned to a fixed position to clamp the next skin material. In this case, the actuator of the clamper provided on the moving body is connected to the fluid pressure supply source by, for example, a coil-shaped supply hose or a supply hose wound around a reel, and the fluid pressure is supplied to the fluid pressure supply source. It is generally practiced to cause the clamper to perform a clamp / unclamp operation by switching and supplying from an actuator to the actuator via a supply hose.

(Problems to be solved by the invention) However, in the above-mentioned conventional method, when the supply hose has a coil shape, it expands and contracts as the moving body moves. There was a problem that the part was cracked and the durability was poor. Further, in the case where the supply hose is wound around a reel, there is a problem in that it is unusable because it hangs down while the moving body is moving. Further, since the moving body is connected to the fluid pressure supply source by the supply hose, there is a problem that the degree of freedom of movement is poor. In addition, when the moving body is moved into the heating furnace as described above, there is a problem that no matter how excellent the heat resistance of the supply hose is used, it deteriorates early due to heat and cannot be used.

The present invention has been made in view of the above points, and an object of the present invention is to clamp and unclamp the clamper actuator and the fluid pressure supply source while the moving body is moving. By taking appropriate measures to perform the clamping operation, it is not necessary to always connect the actuator of the clamper and the fluid pressure supply source with the supply hose, and therefore, it is sufficiently durable for long-term use and easy to use. It is an object of the present invention to provide a fluid pressure supply device which has a high degree of freedom of movement and can be sufficiently used even under severe conditions such as a heating furnace.

(Means for Solving the Problem) In order to achieve the above object, the solution means of the present invention is provided in a moving body, and clamps an article in the process of the moving body moving between a fixed position and a work area. -For a device that supplies fluid pressure to the actuator of the clamper to be unclamped, in this case, the first connection tool connected to the fluid pressure supply source is provided at the fixed position. Further, a storage tank for storing the fluid pressure is provided in the moving body. In addition, the second in the storage tank
A fluid pressure is provided by connecting the connection tool to the first connection tool so as to be separable from the first connection tool, and by connecting the second connection tool with the first connection tool when the movable body returns to a fixed position. Supply to the storage tank. In addition, switching means is provided between the storage tank and the actuator of the clamper, and the switching means switches and supplies the fluid pressure in the storage tank to the actuator so that the clamper can perform the clamp / unclamp operation. .

(Operation) With the above configuration, in the present invention, when the moving body returns to the fixed position, the second connection tool on the storage tank side and the first connection tool on the fluid pressure supply source side are connected to each other, and the fluid pressure changes to the above fluid. It is supplied from the pressure supply source to the storage tank and stored. Then, when the first connecting tool and the second connecting tool are separated and the movable body moves between the fixed position and the work area, the switching means provided between the storage tank and the actuator of the clamper. The fluid pressure in the storage tank is switched and supplied to the actuator, and the clamper is clamped and unclamped to clamp and unclamp the article.

As described above, since the actuator of the clamper and the fluid pressure supply source are disconnected during the movement of the moving body, it is necessary to always connect the actuator of the clamper and the fluid pressure supply source with the supply hose. As a result, a fluid pressure supply device that can withstand long-term use, is easy to use, has a high degree of freedom of movement, and can be used sufficiently even under severe conditions such as a heating furnace is provided. It will be.
