Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a workpiece conveyance device for conveying a workpiece such as a printed circuit board or a printing plate in a press machine used in a punching system.

2. Description of the Related Art A feeder table c that guides the work b held by a work clamper a when the work b is transported to the press k side is provided with a large number of guide members d on which the work b slides. As shown in FIGS. 5 and 6, these guide members d are provided with a holder h that rotatably holds a sphere g in a case f that is fitted into a fitting recess e of a feeder table c, and is supported by a spring i. The sphere g was made to protrude above the case f.

Problems to be solved by the invention: Workpiece clamper a that grips workpiece b has a lower part j that protrudes below workpiece b, and workpiece clamper a causes workpiece b to move toward the sphere g of guide member d.
When moving above, the lower part j interferes with the sphere g, and this sphere g sinks downward against the spring i,
Since it is a collision between rigid bodies, there is some resistance.
This caused trouble in transporting workpiece b, causing damage to workpiece b.

The present invention has been developed in view of the above circumstances, and its purpose is to not only allow workpieces to be transported without resistance, but also to transport workpieces such as printed circuit boards and printing boards without causing any damage to the workpieces. An object of the present invention is to provide a workpiece conveyance device for a press machine suitable for conveyance.

Means and Effects for Solving the Problems The present invention provides a large number of brushes on the upper surface of the feeder table 6 that guides the workpiece 14 held by the workpiece clamper 7 when the workpiece 14 is carried into and out of the press machine 1. 8 are provided at predetermined intervals, and when the work 14 is carried into and out of the press 1, the work 14 is supported by the brush 8, and the work 14 is moved by sliding on the brush 8. This is what I did.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4. 1 is a press machine, and the press machine 1 is equipped with a slide 2 and a bolster 3. The slide 2 is provided with an upper die 4, and the bolster 3 is provided with a lower die 5.

6 is a feeder table, and 7 is a work clamper.

There are many brushes 8 on the top surface of the feeder table 6.
are planted at predetermined intervals, the heights of these brushes 8 are all the same, and the upper ends of the brushes 8 are arranged to be in the same plane as the upper surface of the lower mold 5.

The work clamper 7 is attached to the piston rod 10 of the clamp cylinder 9 as shown in FIG.
A work gripping section 11 is provided at the tip of the work clamper 7.
is formed.

The above-mentioned brush 8 is made of nylon wire material 1.
2 are bundled together and fixed in a mounting hole 13 provided in the feeder table 6.

Therefore, the work gripping portion 1 of the work clamper 7
The plate-shaped work 14 gripped by the feed carrier 16 is sent from the side of the press 1 to the front of the press 1, and is punched by lowering the upper die 4 as the slide 2 lowers. The workpiece 14 is carried out of the press 1 by the operation of the field carrier 16. When the workpiece 14 is carried in and out, the workpiece 14 is placed on a large number of brushes 8 on the feeder table 6 and slides on the brushes 8. do.

The lower part 15 of the workpiece gripping part 11 of the workpiece clamper 7 protrudes below the workpiece 14, but even if this protruding lower part 15 comes into contact with the brush 8, interference of the lower part 15 is avoided so that the brush 8 can escape. .

Effects of the Invention Since the present invention is as described above, the work 14 can be supported by the brush 8 and fed by sliding on the brush 8 when the work 14 is carried into and out of the press machine.

For this reason, even if the lower portion 15 of the work clamper 7 that protrudes below the work 14 comes into contact with the brush 8, the brush 8 escapes and interference can be avoided, and the work 14 can be transported without resistance. Compared to conventional spherical guide members, the workpiece 14 is less likely to be damaged, making it suitable for transporting workpieces 14 such as printed circuit boards and printing plates.
