BACKGROUND OF THE INVENTION
The present invention relates to a technology for conveying metal and resin-based short thin materials.
[0002]
[Prior art]
In general, belt rollers are used as a method of conveying materials in devices that inspect metal or resin-based short thin materials with a thickness of 0.2 to 0.7 mm by visual inspection or image processing, or devices that perform processing such as marking and taping. There are a method of transporting a material on top, a method of transporting the material by sandwiching the material with a roller, and a method of transporting a linearly moving guide with the material mounted using a belt or a ball screw.
[0003]
[Problems to be solved by the invention]
However, the method of transporting the material sandwiched between rollers and the method of transporting the material on the belt can perform high-speed transport, but the vibration and feed unevenness of the material at the time of feeding influences, and a recent image processing device is used. It is not suitable for feeding with high-precision measurement and inspection.
[0004]
In addition, the method of transporting using a linearly moving guide has good transport accuracy, but the material on the delivery stage moves while the linearly moving guide moves to the origin position at high speed, so that the material accurately moves onto the transport guide. There is a problem that mechanical damage is caused because it is not placed, and even if a material is placed on the conveyance guide, displacement occurs in the traveling direction.
[0005]
In addition, when a jig for position correction is provided in the width direction of the material, if there are multiple delivery stages, it must be installed so as to avoid the conveyance guide. There is a problem that it is difficult to install tools.
[0006]
Therefore, the present invention has good conveyance accuracy, can take a sufficient space above and below the conveyance guide, and positions the width direction of the material so as to stably convey while preventing positional deviation during conveyance. It is an object of the present invention to provide a transport apparatus and a transport method that can move a plurality of materials to a delivery location at the same time.
[0007]
[Means for Solving the Problems]
In order to achieve the above-described object, the present invention has a function of placing a short thin material on a conveyance guide and linearly moving the material, so that the lifting / lowering delivery stage guide can be moved up and down at regular intervals on the conveyance guide composed of two rods . There is a gap between the two rods , and at least two pairs of claws of the raising / lowering delivery stage guide (hereinafter sometimes simply referred to as raising / lowering guide) move up and down in the gap to receive the material. The claw is moved in the material width direction (approaching or moving away) to move the conveyance guide to the origin position at a high speed with the material positioned and fixed.
[0008]
Even if there are several delivery positions, the transport guide position and the elevation delivery stage guide can be moved in conjunction with the material width, and the elevation delivery stage guide has a function to move up and down in conjunction with the material width. There is a lifting / lowering stage guide that can be stored on the lower side so that there is no obstacle on the upper side.
