Abstract

PURPOSE:To accurately and continuously sort thin-sheet works which can be warped by spacing the sorters rotatably at the basic dimension of the work, charging the works between the upper and lower turntables and separating works into the passed work and unpassed work which are respectively discharged. CONSTITUTION:A gage plate 12 for sorting the works into the acceptable and unacceptable ones from their thickness is formed by spacing the upper ceramic turntable 21 and lower ceramic turntable 22 at the interval of the basic size of the work. The turntables 21 and 22 are rotated by a gage plate driving part 13, and the works are charged to the gage plate 12 from a chuter 11. Consequently, the acceptable work is passed between the turntables 21 and 22 and discharged onto a conveyor 25, and the unacceptable work is not passed between the turntables 21 and 22 but moved along the periphery of the lower turntable 22 and discharged into a container 26.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external dimension selecting device such as a maximum thickness selecting device for selecting a thin plate-shaped body having a maximum thickness including sleds and swells.

[0002]

2. Description of the Related Art Conventional maximum thickness selection includes a thickness gauge selection method using a glass plate and a representative point measurement selection method using a micrometer or a displacement sensor. First,
Although it is a thickness gauge selection method, as shown in FIG. 6, block gauges 101 and 101 having the same thickness as the maximum thickness to be the selection standard
Are separated by a predetermined distance, and two flat plates 102 and 103 are placed.
Use the sorting gauge 104 sandwiched between
This is a method of selecting whether or not the thin plate-shaped workpiece 105 passes between the flat plate 102 and the flat plate 103 of 04.

Next, the representative point measuring and selecting method is shown in FIG.
As shown in FIG. 8, the surface position of the representative point (or the representative line) is measured, and the maximum thickness is calculated and selected accordingly. In the representative point measurement / selection method of FIG. 7, the position of the representative measurement point 206 of the work 205 is measured by the micrometer 207.

In the representative line measuring and selecting method of FIG.
The displacement sensor 309 is moved along the representative measurement line 308 of 1.

[0005]

However, each of these conventional selection methods has the following problems.
In the thickness gauge selection method, the work 105 having an inferior thickness is retained in the selection gauge 104 depending on whether it is sandwiched between the flat plates 102 and 103 or not, and the next work 105 cannot be loaded. Further, if the works 105 are continuously input, the works 105 collide with each other, causing chipping of the works 105. Further, the work 105 is not clogged uniformly, which makes it difficult to automate. Moreover, the flat plates 102 and 103 are worn and the sorting accuracy deteriorates.

Next, in the representative point measurement / selection method, the representative point 206 is measured only, and the true maximum thickness cannot be measured. In addition, in order to improve accuracy, the measurement point 206
Must be increased, and the processing of data takes time and the processing speed is slow. Furthermore, in the representative line measurement selection method,
A complicated numerical operation is required for the data obtained by the movement of the displacement sensor 309, which not only makes the device expensive but also slows the processing speed.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail based on a specific embodiment as a maximum thickness selecting device shown in the accompanying drawings. As shown in FIG. 1, the maximum thickness sorting apparatus for thin plate-shaped bodies includes a work supply unit 1, a sorting mechanism unit 2, and a work take-up unit 3.

The work supply unit 1 is equipped with a parts feeder. As shown in FIG. 2, the selection mechanism section 2 includes a shooter section 11 for introducing a work, a selection gauge plate section 12 for selecting a work into a good product having a thickness less than a predetermined thickness and a defective product having a thickness more than a predetermined thickness. A gauge plate driving unit 13 such as a motor for driving the gauge plate unit 12, a defective product discharging unit 14 for flowing the sorted defective work, and a non-defective discharging unit 15 for passing the sorted good work.

Further, as shown in FIG. 3, the sorting gauge plate portion 12 comprises an upper ceramic rotating plate 21, a lower ceramic rotating plate 22, a sorting thickness spacer 23 and a defective product discharging spacer 24. Disk-shaped lower ceramic rotating plate
22 is rotatably arranged in the central portion of a rectangular stationary frame 31, and is provided above the lower ceramic rotary plate 22 with a space of the maximum thickness of the workpiece, which is a reference dimension, and has a diameter smaller than that of the lower ceramic rotary plate 22. A disc-shaped upper ceramic rotating plate (21) is concentrically arranged and fixed to a drive shaft of a gauge plate driving unit (13) so that the lower ceramic rotating plate (22) and the upper ceramic rotating plate (21) can rotate together. The selection thickness spacer 23 is fixed to the central portion between the lower ceramic rotary plate 22 and the upper ceramic rotary plate 21. Similarly, the defective product discharge spacer 24 is also provided between the lower ceramic rotary plate 22 and the upper ceramic rotary plate 21 so as to be stationary in the radial direction. Further, the outer peripheral portion of the lower surface of the upper ceramic rotary plate 21 is chamfered into a C surface shape.

The work pick-up section 3 is divided into picking of good products and picking of defective products. Good products are picked up by the conveyor 25 and defective products are collected in the container 26. Next, the operation of this maximum thickness selection device will be described. Work supply unit 1
Cuts out the works one by one with a parts feeder at a constant interval and supplies them to the sorting mechanism unit 2.

As shown in FIG. 4, the supplied work 32 passes through the shooter portion 11 and is introduced into the sorting zone of the sorting gauge plate portion 12 in the direction A. The lower ceramic rotating plate 22 and the upper ceramic rotating plate 21 are rotated in the direction B, which is the opposite direction to the traveling direction of the work 32, and the number of rotations can be arbitrarily set by an inverter or the like. If the input work 32 is thinner than the selection thickness spacer 23, which is the maximum allowable thickness, the lower ceramic rotating plate 22
