Description

Detailed Description of the Invention A. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a test piece alignment device for positioning test pieces stocked on a test piece stock shelf.

B. Conventional technology Generally, in an automatic material testing machine for dumbbell-type test pieces, a plurality of test pieces are stacked on a stock shelf, and, for example, they are suction-held one by one from the top by a suction pad and conveyed to the measuring device in the next process. Then, after measuring, the test piece is automatically attached to the grip and the test is performed. Therefore, if the suction pad comes off from the test piece during the suction operation, the test piece cannot be conveyed to the next step, so it is necessary to make sure contact.

However, conventionally, a pair of positioning members are erected in the stacking direction of the test pieces, and the test piece TP is brought into contact with the members so that the longitudinal center line and the width center line thereof are in the same direction of the stock shelf. The center line of the test piece was substantially aligned with the center line of the test piece so that the test piece was surely sucked to the suction pad.

C. Problems to be Solved by the Invention However, there are a plurality of shapes of the test piece, and there is a problem that the positioning cannot be accurately performed with the fixed positioning member depending on the shape of the test piece.

An object of the present invention is to provide a test piece aligning device for a test piece stock shelf that solves the above problems.

D. MEANS FOR SOLVING THE PROBLEMS The present invention is installed in a shelf for stacking and stacking a plurality of dumbbell-shaped test pieces, and a stock in which a longitudinal centerline and a widthwise centerline of the test pieces are predetermined. It is carried out on a test piece aligning device that aligns the longitudinal centerline and the widthwise centerline of a shelf in a substantially aligned manner. In order to solve the above problems, the present invention provides
It has a pair of guide members that are arranged so as to be distributed with respect to the center line in the width direction of the stock shelf. The guide member abuts on the constricted portion of the test piece to determine the position of the test piece in the longitudinal direction and the width direction. Then, by adjusting the longitudinal distance between the pair of guide members to adjust the widthwise center lines of the test piece and the stock rack to substantially coincide with each other, the position of the pair of guide members in the width direction is adjusted. The test piece and the stock rack are provided with a longitudinal adjustment mechanism for substantially aligning the longitudinal centerlines of both.

E. Action The width direction adjusting mechanism can adjust the distance between the pair of guide members in the longitudinal direction so that the width direction center line of the test piece and the width direction center line of the stock shelf can be substantially aligned with each other. Further, the longitudinal direction adjusting mechanism can adjust the widthwise positions of the pair of guide members so that the longitudinal centerline of the test piece and the longitudinal centerline of the stock rack can be substantially aligned with each other. Therefore, for example, if a test piece suction device is provided so that the widthwise and lengthwise centerlines thereof coincide with both centerlines of the stock rack, a pair of suction pads can be placed on the lengthwise centerline of the test piece by the above operation. In addition, since the test pieces come into contact with each other at positions symmetrical with respect to the center line in the width direction, the suction can be surely performed regardless of the shape of the test piece.

F. Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 (a) and 1 (b).

(I) Configuration of Example FIG. 1 (a) is a front view showing a schematic configuration of a test piece stock shelf, and FIG. 1 (b) is a top view thereof. A vertical slit 1a as shown in FIG. 1 (b) is formed on each of the pair of columns 1 standing on the floor, and the protrusions 2a provided on the left and right of the table 2 are formed in the slits 1a. The table 2 is inserted and guided up and down. Further, a shaft 5 is connected to an output shaft 3a of the motor 3 installed on the floor via a coupling 4, and the shaft 5 includes a pair of columns 1
It is rotatably supported by. A pair of sprockets 6 is attached to both ends of the shaft 5 integrally with the shaft 5, and a chain 8 is respectively hung between the sprockets 6 and the sprockets 7 rotatably provided on the upper portions of the columns 1. It has been passed. One end of each chain 8 is the table 2
And the other end is fixed to the lower surface of the protruding portion 2a. Therefore, the table 2 moves up and down along the slit 1a by the rotation of the sprocket 6.

A dumbbell-shaped test piece TP as shown in FIG. 1 (b) is stacked and stocked on the upper portion of the table 2. The shape of the test piece TP is standardized based on the parallel portion length PL and the parallel portion width PW, and there are a plurality of types having different dimensions. Normally, the test pieces TP for one lot, which are stacked at one time, have a parallel portion length PL and a parallel portion width P.
The same W is the same.

On the other hand, a nut 21 is fixedly mounted on a fixed base 20 (see FIG. 1 (b)) provided at the rear of the table 2, and a screw rod 10 extending forward of the stock shelf is screwed into the nut 21. Has been done. The screw rod 10 rotatably penetrates through the movable support member 9 arranged in front of the fixed base 20, and when the screw rod 10 is rotated by rotating the handle 11 at its tip, the movable support member 9 is Guided by the illustrated guide, the stock shelves move in the front-back direction (vertical direction in FIG. 1B).

Both ends of a screw rod 12 are rotatably supported by both side walls of the movable support member 9 formed in a U-shape so as to extend in the longitudinal direction of the test piece TP, and the screw rod 12 is vertically supported. Both ends of the pair of guide shafts 13 arranged are attached respectively. The guide shaft 13 is not shown in FIG. 1 (b). The threaded rod 12 is composed of a pair of threaded portions 12a and 12b in which threads are formed in opposite directions, and nuts 14a and 14b are screwed into the threaded portions 12a and 12b, respectively. A pair of left and right test piece guide members 15a and 15b extending in the stacking direction of the test pieces TP are fixed to the front surfaces of the stock shelves of the nuts 14a and 14b.
On the other hand, the pair of guide shafts 13 has slide bearings 16a, 1
6b are attached to the slide bearings 16a, 1
The top and bottom of the guide members 15a and 15b are fixed to 6b. That is, the guide members 15a and 15b are slidable on the pair of upper and lower guide shafts 13.

A handle 17 is connected to one end of the threaded portion 12b, and when the screw rod 12 is rotated by rotating the handle 17, the pair of guide members 15a and 15b causes the vertical guide shaft 1 to move.
Guided by 3 and separate from each other. At this time, the positions of the two guide members 15a and 15b are always symmetrical with respect to the center line of the stock rack in the width direction (sorting position).

Further, as shown in FIG. 1 (b),
Pressers 19 are attached via attachment members 18, respectively, and the test piece TP is brought into contact with the guide members 15a and 15b by the spring force of a spring (not shown) or the like.

The suction device 30 of the test strip transporting device is arranged in the upper space of the test strip stock rack thus configured. The suction device 30 includes a holding member 31 connected to the main body of the transport device.
And a pair of suction pads 32 attached to the holding member 31, and a limit switch LS that is turned on when the test piece TP comes into contact with the suction pad 32. The suction device 30 is turned on when the limit switch LS is turned on. Is operated to adsorb the test piece TP to the adsorption pad 32, and the test piece TP is conveyed to, for example, a measuring device in the next step for measuring the width and thickness of the test piece TP. Here, the widthwise and longitudinal centerlines of the suction device 30 are
It is preset to match that of the stock shelves.

(II) Operation of Example One lot of test piece TP laminated on the upper part of Table 2
Before the sheets are conveyed to the measuring device one by one by the conveying device, the test pieces are aligned as follows. First, handle 11
To rotate the screw rod 10 to guide the guide members 15a, 1
5b is moved in the width direction of the test piece TP, that is, in the front-back direction of the stock shelf, so that the longitudinal centerline l ₁ of the test piece TP coincides with the longitudinal centerline of the stock shelf. Since the horizontal centerline of the stock rack and the horizontal centerline of the suction device 30 are coincident with each other, this operation causes the longitudinal centerline l ₁ of the test piece TP and the horizontal centerline of the suction device 32 to coincide with each other. .

Next, the screw rod 12 is rotated by the handle 17 to move both guide members 15a and 15b in the longitudinal direction of the test piece TP, that is, in the left-right direction of the stock rack, and the guide members 1
5a and 15b are positioned at both ends of the constricted portion A of the test piece TP. Thus the width direction center line l ₂ and the stock shelf of the test piece TP, that is, the center line of the suction device 30 to match.

Then, the motor 3 is driven to raise the table 2.
When the uppermost test piece TP among the test pieces TP stacked on the table 2 comes into contact with the suction pad 32, the limit switch LS is turned on and the motor 3 is stopped. On the other hand, when the limit switch LS is turned on, the suction device 30 operates,
The uppermost test piece TP is adsorbed by the adsorption pad 32 and conveyed to a measuring device (not shown).

After that, when the suction device 30 is again positioned at a predetermined position on the upper part of the stock shelf, the motor 3 is driven again and the table 2 is moved.
Rises, and the uppermost test piece TP is adsorbed by the adsorption pad 32 as described above. By repeating this, the set one lot of the test pieces TP are transported.

As described above, by operating the handles 17 and 11, regardless of the shape of the test piece TP, the center line in the width direction and the center line in the longitudinal direction of the test piece TP and the center line in the width direction and the center line in the longitudinal direction of the stock shelf are set. They can be made to match each other.
As a result, the center lines of the test piece TP and the suction device 30 in both directions coincide with each other, so that the pair of suction pads 32 are symmetrical with respect to the longitudinal center line l _{1 of the} test piece TP and with respect to the width direction center line l ₂ . The test piece TP is brought into contact with the test piece TP at a position, and the suction is surely performed regardless of the parallel portion length PL and the parallel portion width PW of the test piece TP.

In the configuration of the above embodiment, the handle 17 and the screw rod 1
2 and the nuts 14a and 14b constitute a width direction adjusting mechanism, and the handle 11, the screw rod 10 and the nut 21 constitute a longitudinal direction adjusting mechanism.

In the above, the guide member 15 is manually operated by rotating the screw rod.
Although the example in which the a and 15b are driven in the longitudinal direction and the width direction has been shown, these may be driven by, for example, a motor or a cylinder. Further, the shapes of the guide members 15a and 15b are not limited to those of the embodiment. Further, although the test piece is gripped by the suction method, a magnet method or a gripping method may be used.

It is preferable to provide the scales 51 and 52 indicating the positions of the guide members 15a and 15b as shown by the chain double-dashed line in FIG. 1 (b) because the usability is improved.

G. Effect of the Invention Since the present invention is configured as described above, regardless of the shape of the test piece, the widthwise center line and the longitudinal centerline of the test piece, and the widthwise centerline and the longitudinal centerline of the stock shelf are If a pair of suction pads are positioned with respect to the stock shelf, the pair of suction pads will be symmetrical on the longitudinal centerline of the test piece and symmetrical with respect to the widthwise centerline. The test pieces come into contact with each other at the respective positions, so that the suction can be surely performed regardless of the shape of the test piece.
