Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel centering method that can accommodate various panel shapes during panel loading of a press machine.

For example, when a panel that has been primarily formed in one press device is transported and loaded to the next press device, if the loading into the next press device is performed by an automatic machine, the panel that has been primarily formed and transported is Panels must be centered accurately before loading.

Further, the centering must be able to easily accommodate not only panels of a certain shape but also panels of various shapes. The present invention provides a panel centering method that satisfies the above conditions, and will be described below with reference to embodiments shown in the accompanying drawings. FIG. 1 is a schematic explanatory diagram of a press line to which the present invention is applied, in which a panel press-formed in a press machine A is conveyed in the direction of the arrow by a conveyor B, and placed on a press die of the next press machine D. The panel is loaded by an automatic machine, but before that, the panel is picked up and centered by a centering device C used in the present invention.

The configuration of the centering device will be explained with reference to FIG.
This device is composed of a number of forming needles 1, a needle support 2 for holding the forming needles 1, a needle clamper 3, a friction clamper 4, a lifting device 5 for lifting these together, and the like.

That is, as shown in FIGS. 3 and 4, the forming needle 1 stands upright so as to be slidable up and down by a friction clamper 4 on a needle support 2 fixed on a machine base 6 which is controlled to rise and fall by a lifting device 5. Supported.

The tips of the plurality of forming needles 1 are fixed by a needle clamper 3 in a state in which they form a three-dimensional shape that fits the inner surface of the centering flat panel 10 as shown in FIG. Such a centering device is installed upstream of a press device that is to be loaded using an automatic machine. Panel 1 was then transported by conveyor B as shown in Figure 1.
0 reaches the centering device, the lifting device 5 operates to lift up the machine platform 6. Then panel 10
is a forming needle 1 that has formed a certain shape in advance.
It is picked up at the tip and is thus accurately positioned. This panel 10 is then loaded onto a press mold using an automatic machine. A specific example of the structure of the holding means for the forming needle 1, such as the needle clamper 3 and the friction clamper 14, is as shown in FIGS. 5 and 6. That is, the friction clamper 14 is composed of a plate spring piece fixed to the needle support 2 as shown in FIG. The needle clamper 3 has an engaging protrusion 3a that engages with a spiral groove 1a provided in the needle 1 as shown in FIG. Movement is controlled to the clamp position and non-clamp position.

Next, a case where the shape of the panel to be centered changes will be explained.

When changing the mold, first, the cylinder device 7 is extended to release the clamp by the needle clamper 13, and then the machine base 6 is lowered by the lifting device 5.

Then, the lower end of the needle 1 is moved to the needle rib ohm plate 9, which is held at a predetermined height by the cylinder device 8.
At this point, all needles 1 become flat. Then, a sample panel of a new shape is pressed onto the forming needle 1 to form the needle 1.

In this case, since the needle 1 is only supported by the friction clamper 14 at a predetermined friction, the tip of the needle easily adapts to the new shape and is formed. When the forming is completed, the needle 1 is fixed by the needle clamper 13 by the cylinder device 7, so that centering of the new shape can be continuously performed. As described above, according to the present invention, accurate centering can be performed with a simple configuration, and panels of various shapes can be easily accommodated. The practical value obtained is extremely large.

Claims (1)

[Claims] 1 As a positioning means when loading a panel press-formed into a certain shape into the next press device, a needle support holding a number of forming needles so that the height can be adjusted is used, and each forming needle is The height of the panel is adjusted and the shape of the panel is fixed at the tip thereof in a three-dimensional state, and the needle support is raised to form the sent panel supported by the needle support. A method for centering loading onto a press machine, characterized in that centering is performed by picking up at the tip of a needle.
