JPH07159149A - Automatic feed of surface roughness test piece of sheet steel - Google Patents

Abstract

PURPOSE:To prevent the taking-out of two test pieces at the same time, and automate the test, by installing shelves in a stocker and accommodating the test pieces one by one reversing the obverse/reverse surfaces by turning a chuck by 180 deg. and changing the measuring direction through the 90 deg. turn. CONSTITUTION:A stocker 1a is taken out from a stocker raising/lowering device 1, and test pieces are set successively from the uppermost shelf according to the testing order on stocker shelves. In this case, the obverse/reverse surfaces and direction of all the test pieces are made the same. For example, the surface is set upward, and the C direction (direction perpendicular to the rolling direction) is set the same as the introducing-in/out direction. The stocker 1a is placed on the raising/lowering device 1, and a start button is pushed to start an automatic test piece feeding device. The raising/lowering device 1 rises by one pitch and stops, and the height of the shelf becomes equal to the height of the chuck 5a. The chuck 5a advances to catch the test piece on the uppermost shelf and pulls out the test piece while retreating, and a handling arm 5b travels on a transfer rail 5c, and stops, and inserts the test piece into a test piece fixing/shift device 4 and retreats, and a roughness meter performs automatic measurement.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an object to prevent two test pieces from being taken in automatic surface roughness measurement of a thin steel sheet.

[0002]

2. Description of the Related Art A plurality of test pieces for one test lot are stacked and inserted in a test piece stocker, taken out one by one by a vacuum suction method, and supplied to a roughness tester. And when the test is completed, it is adsorbed again by the adsorption device,
Store in the tested specimen pallet.

[0003]

In the method of sucking the stacked test pieces with a vacuum suction disk, a small amount of oil attached to the test piece or the pressure when the suction disks are pressed against the test piece is used. As a result of the air between the smooth test pieces being extruded into a vacuum state, a so-called "two-piece picking" may occur in which two test pieces are sucked while attached.

The surface roughness of a thin steel sheet is measured in the same direction as the rolling direction of the steel sheet (L direction) and in the direction perpendicular to the rolling direction (C direction).
There are 4 cases in two directions, front and back sides of the steel plate, and all or part of them are measured, so when supplying the test piece to the roughness meter, arrange it in the direction and surface as instructed. Must be supplied.

When a test piece is manually supplied to a roughness meter, when a defect such as a handling flaw, which is not originally an object of measurement, is found on the measurement surface, it is possible to avoid the portion and set it on the roughness meter. In the automatic supply, it is necessary to set a device avoiding this flaw because of the flaw detection, which requires a large-scale device.

[0006]

[Means for Solving the Problems] In order to prevent two test pieces from being taken out, a shelf is attached to the test piece stocker so that each test piece is stored in the shelf. The test piece is gripped by the chuck of the handling device and supplied to the roughness meter.

As a means for aligning the test piece according to the test instruction, a 180 ° rotation function is added to the test piece chuck mechanism portion so that the front and back surfaces can be selected, and the measurement direction (C direction,
In the (L direction), a test piece swivel device that swivels 90 ° is provided to adjust the test piece in a predetermined direction.

If there is a defect such as a handling flaw on the roughness measurement line of the test piece, it will be displayed as a roughness value and will be input to the control device. Roughness upper and lower limits for each test piece are set in the test instruction information, and if the measurement results are out of the upper and lower limits, the test piece is shifted and one additional measurement is performed. The method of performing

[0009]

Embodiments Embodiments will be described with reference to the drawings.

As shown in FIG. 1, the stocker lifting device 1,
The test piece storage device 2, the test piece swivel device 3, and the test piece fixing and shifting device 4 are arranged in a horizontal row, while the test piece handling and conveying device 5 is arranged.

FIG. 3 is a flow chart showing the automatic test strip supply procedure.

First, from the stocker lifting device to the stocker 1a
Take out the test pieces and set them on the stocker shelf in order from the top according to the test order. In this case, the direction should be unified with the front and back surfaces of all test pieces. For example, the surface faces upward and the C direction is the same as the exit / entry direction. On the other hand, the test conditions for each test piece are input to the control device.

After placing the stocker on the stocker lifting device 1 and fixing it with the fixing lever, the start button is pressed to activate the automatic test strip supply device. The elevating device moves up by one pitch and stops, and at this time, the height position of the shelf and the chuck portion 5a in the test piece handling transfer device 5 are at the same height. The chuck 5a moves forward, grips the uppermost test piece, retracts, and stops at the retracting limit. Here, the controller gives the test conditions for this test piece and moves to the next operation. In this description, all four cases of the front-C direction, the front-L direction, the back-C direction, and the back-L direction will be described as being executed. Since the current test piece is in the front-C direction, the handling arm 5b
Runs on the transport rail 5c (to the right) and stops at the position of the test piece fixing & shifting device 4 mounted on the measuring table of the roughness meter, and stops, and the chuck 5a moves forward to move the test piece to the test piece. The test piece pressing mechanism 4a is inserted into the fixing and shifting device 4 and retracts, and the test piece is fixed.

Here, the roughness meter automatically operates to automatically measure the input measurement item. Since the roughness meter inputs n times (n points) of measurement on the same surface and in the same direction, for example, if the measurement instruction is three times, the sample shift device 4b is set twice by one pitch and is the same. Measure the measurement item three times. When the n-th measurement is completed, each measurement result is compared with the input maximum and minimum values, and if there is an over value, the same measurement item is measured by further shifting by one pitch.

When the measurement is completed, the chuck 5a advances to take out the test piece from the test piece fixing and shifting device 4, and then the control device receives the following measurement conditions.

Since the next measurement is in the front-L direction and the current specimen is in the front-C direction, the handling arm 5b travels on the transport rail 5c (leftward) and the 90 ° turning device 3 for the specimen.
To the position, stop, and move the chuck forward to move the test piece onto the test piece turning device 3 and retract, and the device 3 turns 90 ° to convert the test piece from the C direction to the L direction.

The chuck 5a advances to take out the test piece from the apparatus 3, the handling arm 5b moves rightward again to the test piece fixing & shifting apparatus 4, and the measurement is performed a designated number of times, and the measured value of n times is input. Compare the maximum and minimum values,
If there is a value that has exceeded, if there is not one more time, the process moves to the next measurement.

The next measurement is in the back surface-C direction, and the current sample is in the front surface-L direction. The chuck 5a moves forward, grabs the test piece on the test piece fixing & shifting device 4, retracts and stops, and the chuck 5a rotates 180 ° at that position to convert the test piece from the front surface to the back surface. Next, the handling arm 5b moves to the left and transfers the test piece to the test piece turning device 3 to convert the test piece from the C direction to the L direction, and then moves it again to the test piece fixing & shifting device 4 to measure the roughness.

In this way, the test conditions are compared with the state of the sample currently held by the chuck, and the conversion of the front and back surfaces is determined by the chuck 5
The rotation of a and the conversion in the C and L directions are performed using the sample turning device 3, and the samples are aligned in a designated state and supplied to the roughness meter.

When the measurement of all one test piece is completed, the test piece handling and conveying device 5 has tested the test piece into the test piece storage device 2
And then return to the origin position. Here, the control device checks whether all the test pieces (N pieces) of the lot have been tested. If it is not completed, the stocker lifting device operates again, pushes up the stocker one pitch, stops at the test piece take-out position on the next shelf, the test piece handling transport device operates, takes out the test piece, and the test piece according to the test instruction information. Align and send to the roughness meter. In this way, the test is continued until N sheets in the stocker have been tested.
