Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a pachinko face plate fixing device in a nail hole punching press for pachinko face plates for drilling numerous nail holes in the pachinko face plate. .

[Conventional technology]

A pachinko face plate is made by pasting a melamine plate onto a plywood board, and a gauge with countless perforating needles embedded in the iron plate is pressed against the melamine plate that forms the surface of the pachinko face plate to drill the nail holes (more precisely, under the nails). hole) is drilled.

In order to drill nail holes in a pachinko face plate using a press machine using a gauge with such a configuration, the pachinko face plate that is fed onto the support stand of the press machine must be fixed to the support stand by some means. .

He was holding down the pachinko face plate 34 installed on the top surface of the machine. This method leaves press marks from the presser tool 33 on both ends of the upper surface of the pachinko face plate 34, and requires a separate device to feed the pachinko face plate 34 forward from the support base 31 after drilling the nail holes. The problem was that it became complicated.

[Problem that the invention attempts to solve]

In view of the above-mentioned problems, the present invention has been developed to support the pachinko face plate separately without damaging both ends of the top surface, and without the pachinko face plate being lifted up integrally with the gauge when the gauge is raised. This was done for the purpose of fixing a pachinko face plate to a support stand of a press machine without providing a device for feeding it out from the stand.

[Means for solving problems]

The pachinko face plate fixing device according to the present invention forms a fixing roller in which two flanges are provided at the upper end with an interval slightly larger than the thickness of the pachinko face plate, and the width of the pachinko face plate is adjusted to the width of the pachinko face plate. Correspondingly, a large number of fixing rollers are supported on both sides of the support stand of the press so that they are perpendicular to the moving direction of the pachinko face plate and are rotatable to drive, so that the rollers are supported at the front and rear ends of the pachinko face plate during drilling. Each stopper plate for regulating the position is provided at the front and rear of the support base so as to be able to be raised and lowered, and both ends of the pachinko face plate in the width direction are inserted between the respective flanges of the fixing roller to adjust the width. While regulating the position of the fixing roller with the fixing roller, and regulating its front and rear end positions with the respective stopper plates, drill the nail holes in the pachinko face plate. It is characterized in that the pachinko face plate is lightly hooked onto the collar body to prevent the pachinko face plate from being lifted up integrally with the gauge.

[Effect of invention]

If a large number of fixing rollers provided on both sides of the support stand of the press are driven to rotate, and a stopper plate for regulating the front end position of the pachinko face plate is raised, the fixing rollers will be rotated. Both ends of the pachinko face plate fit between the upper and lower collar bodies, and the pachinko face plate moves forward on the support base by the drive rotation of the fixing roller and comes into contact with a stopper plate for regulating the front end position.

When the front end surface of the pachinko face plate comes into contact with the stopper plate, the rotation of the fixing roller stops, and another stopper plate for regulating the fixing position of the rear end of the pachinko face plate rises, causing the support stand to stop. The pachinko face plate is fixed to the support base in a position determined by a large number of fixing rollers provided on both sides and each stopper plate provided at the front and rear ends of the support base, and nail holes are drilled in this state. .

When the gauge is raised after drilling the nail holes, both ends of the pachinko face plate are lightly caught by the upper collar provided on the fixing roller, and the nails of the cage that have bitten into the pachinko face plate are removed from the pachinko machine. Get out of the faceplate. Thereby, the gauge and the pachinko face plate are reliably separated from each other without being lifted up together with the gauge. Thereafter, the stopper plates provided at the front and rear ends of the support stand are lowered, and the fixing rollers are driven and rotated again, so that the pachinko face plate on the support stand, which has finished drilling the nail holes, is sent forward.
