DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band saw processing system for removing a work from a three-dimensional warehouse, and
The present invention relates to a band saw processing system for measuring the shape and size of a work when cutting with a sawing machine .

[0002]

2. Description of the Related Art In a work processing line system, a work accommodated in a three-dimensional warehouse is taken out by a crane, mounted on a band saw (band sawing machine), and cut by a saw blade. At this time, the determination of the shape and dimensions of the work has been conventionally determined by an operator.

[0003]

By the way, when taking out a work in a three-dimensional warehouse, it is often necessary to take out an erroneous work without knowing whether it is the designated work and replace it later. Further, since the diameter of the work mounted on the band sawing machine needs to be determined and input in advance by an operator, there is a possibility that a difference in the determination may occur.
It should be noted that the work was not known whether the geometry, such as throat.

[0004] It is an object of the present invention to improve the above-mentioned problems, it is easy to reliably select a work when taking it out of a three-dimensional warehouse, and it is possible to automatically input the shape and dimensions of a work mounted on a sawing machine. To provide a band saw processing system.

DETAILED DESCRIPTION FIG. 1 shows a schematic configuration diagram according to the present invention. In the figure, a large number of shelves 3 are provided in a three-dimensional warehouse 1, and a long work W cut by a sawing machine is accommodated on the shelves 3.

A crane 5 that moves up and down along the three-dimensional warehouse 1 has a displacement sensor, for example, a laser sensor 7.
And a work shape measuring device 21 including a sensor movement arm 9 for allowing the laser sensor 7 to freely move back and forth and a work shape calculator (position gauge) 11 for calculating the shape and dimensions of the work W.

The laser sensor 7 detects the distance to a point on the workpiece W in a non-contact manner by the emitted laser light. The sensor moving arm 9 is directly moved with respect to the longitudinal direction of the workpiece W by a moving screw 13 driven by a driving device (not shown).
The workpiece W is moved in the
Detect multiple points above.

The work shape calculator 11 calculates the shape and size of the work, for example, the diameter, from the movement signals at a plurality of points by the sensor movement arm 9 and the laser sensor signals at the plurality of points.

[0013] configured in this way, of the workpiece W shape dimensions
When the method (e.g., diameter) is measured, a comparison with the set diameter of the work is performed, and when the diameter of the work W is different, the unloading is stopped, and the sorting of the work W is appropriate, reliable and easy. is there.

FIG. 2 is an explanatory diagram showing a method of measuring the shape and dimension of a work. In the figure, the laser sensor 7 is moved in the horizontal direction, and the distance P3, P2, P1, P0, P-1, to the work W1 or W2 at a certain measurement position for each sampling frequency Δx.
Measure P-2, P-3 or P'3, P'2, P'1, P'0, P'-1, P'-2, P'-3. These measurement points P3, P2, P1, P0, P-1, P-2, P-3 or
Out of the points P'3, P'2, P'1, P'0, P'-1, P'-2, P'-3, the outer points a and b are discarded and appropriate as shown in FIG. And the circle C passing through the three points is calculated by the position gauge 11.

I want to use all measurement points (data),
This is because the calculation is easier and faster if three points are taken. Note that Sa in the figure indicates a stable measurement area of the laser sensor 7. In this way, by calculating the outer dimensions of the work W1 or W2, the work W
Applicable to the management of

Next, in FIG. 4 , the fixed vise 15 of the band saw 12 has a laser sensor 7 and the laser sensor 7.
A work shape measuring device 21A including a sensor moving arm 9 for freely moving the work W and a position gauge 11 for calculating the shape and dimensions of the work W is mounted. The diameter of the work W fixed to the fixed vise 15 is automatically measured, and unmanned operation is achieved.

Next, in FIG. 5 , the shape and dimensions of a laser sensor 7, a sensor moving arm 9A for attaching the laser sensor 7 and freely moving in the left and right direction, and a workpiece W are provided on a saw blade housing portion 17 of the band saw machine 12. Is mounted on the workpiece shape measuring device 21B including the position gauge 11 for calculating the value. Therefore, the diameter of the work W fixed to the fixed vise 15 can be automatically measured, and unmanned operation is achieved.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but can be carried out in other modes by making appropriate design changes. Not only the shape but also the square shape can be measured, and the dimension measurement other than the diameter measurement is also possible.
