The present invention relates to a polygonal member positioning device that can be used to determine whether a member is front or back and to position it at a predetermined position.

[Prior Art] Taking the glass of a rear quarter window as a polygonal member as an example, conventional rear quarter windows that are integrally molded with glass require the work of applying adhesive around the polygonal glass and the forming process. The attachment to the mold was done manually.

[Problems to be solved by the invention] However, in cases such as rear quarter windows that are integrally molded with glass, it is difficult to manually apply adhesive around the polygonal glass and to attach it to the mold during molding. Even when the process was carried out, there were many judgment factors due to the complexity of the shape, and the workability was not good.

For example, even when only applying adhesive, first determine the surface of the glass → position the glass →
It is necessary to go through the process of applying adhesive → determining the back side of the glass → positioning the glass → applying adhesive, and due to the complexity of the process, even if a jig is used, it is difficult to determine the front side of the glass and position it. It required a variety of judgments, and there were problems in increasing efficiency.

Therefore, the present invention has been devised to eliminate the above-mentioned problems, and aims to provide a polygonal member positioning device that can efficiently determine the front and back sides of a polygonal member and perform positioning.

The left side first support piece 23 is used to firmly attach the left side first actuator 24 for reciprocating the left side first piston rod 25 to the set base 1. The first left actuator 24 of the first left actuator 24
The piston rod 25 is fixed to a left first angle detection member 26 that moves along the upper surface of the set base 1. The angle setting surface 26a of the left first angle detection member 26 on the opposite side to which the left first piston rod 25 is connected is processed into a planar shape.

Further, the second left support piece 43 is used to firmly attach the second left actuator 44 for reciprocating the second left piston rod 45 to the set base 1.

The angle setting surface 46a of the left second angle detection member 46 on the opposite side to which the left second piston rod 45 is connected is processed into a planar shape.

The reference positioning members 7 constituting the reference position determining means are arranged independently on both sides of the perpendicular line of the reference surface 7a, and the symmetrical angles are detected with respect to each other.
This constitutes a two-sided position determining means.

The polygonal member positioning device of this embodiment configured as described above can be operated as follows.

First, it is assumed that the glass is suctioned and clamped by the suction pad 2 of the manipulator and placed on the set base 1 like the glass 50 for a rear quarter window as a polygonal member in FIG. Note that the surface 50a of the glass 50 is the upper surface shown in FIG. Further, the glass 50 has sides 51, 52, 5
It has 3,54.

With the glass 50 placed on the set base 1, as shown in FIG. The surface 7a is moved toward the notch 1a and stopped at the set amount of extension.

Then, the right side first angle detection element and the left side second angle detection element are operated, the right side first actuator 14 constituting the right side first angle detection element is operated, the right side first piston rod 15 is extended, and the set base 1 is moved. Right side first angle detection member 1 along the top surface
6 to the notch 1a side and stop at the set amount of extension. Further, actuating the second left actuator 44 that constitutes the second left angle detection element,
The left second piston rod 45 is extended, the left second angle detection member 46 is moved toward the reference position member 7 along the upper surface of the set base 1, and stopped at the set extension amount.

In this case, the right side first angle detection element and the left side second angle detection element are connected to the right side first angle detection member 16.
The angle setting surface 16a of the glass 50 matches the side 53 of the glass 50, and the angle setting surface 4 of the left second angle detection member 46
6a and the side 52 of the glass 50 match. That is,
The angle formed by the angle setting surface 16a and the angle setting surface 46a matches the angle formed by the sides 52 and 53 of the glass 50. At the same time, in the state shown in FIG.
1 match, the angle formed by the angle setting surface 16a and the reference surface 7a and the side 53 of the glass 50
and the angle formed by the side 51 match, and the angle setting surface 4
6a and the reference surface 7a and the angle formed by the glass 50
The angles formed by sides 51 and 52 match. At this time, when the reference surface 7a of the reference position member 7 constituting the reference position determining means and the side 51 of the glass 50 do not completely match, or when the reference surface 7a and the side 51 are similar shapes that perfectly match, The spring 9a is displaced within the range of the allowable error and absorbs it.

On the other hand, like the rear quarter window glass 50 as a polygonal member shown in FIG. Notch 1
When the piston rod 35 is moved to the a side and stopped at the set extension amount, and the right side second angle detection element and the left side first angle detection element are operated, the right second piston rod 35 constituting the right side second angle detection element is extended. or the amount of extension of the right first piston rod 25 constituting the left first angle detection element will be different from the set value. In this case, glass 5 for the rear quarter window is used as a polygonal member.
It is determined that the top surface of 0 is the back surface 50b, or that it is non-standard.

Therefore, by determining this condition,
The glass 50 is set on the surface 50a of the glass 50 and a specific location on the set base 1, and positioning can be performed.

When applying adhesive or the like to the upper surface 50a of the rear quarter window glass 50 in this state, highly accurate control can be performed.
In addition, when the predetermined work on the surface 50a of the glass 50 is completed, the suction pad 2 of the manipulator is
It may be adsorbed and clamped with a tool such as the like, and then turned over. In this case as well, in order to position the back surface 50b of the glass 50 at a specific location on the set base 1, the same operation as the former may be performed.

That is, as shown in FIG. 3 with the glass 50 placed on the set base 1, the reference surface 7a of the reference position member 7 constituting the reference position determining means is moved toward the notch 1a side to achieve the set elongation. stop at the amount.

Then, the right side second angle detection element and the left side first angle detection element are operated, the right side second piston rod 35 constituting the right side second angle detection element is extended, and the right side second angle detection member 36 is moved to the reference position member 7 side. , and stop at the set extension amount. Furthermore,
The left side first piston rod 25 constituting the left side first angle detection element is extended, and the left side first angle detection member 26 is extended.
is moved toward the notch 1a side and stopped at the set elongation amount.

In this case, the right side second angle detection element and the left side first angle detection element are connected to the right side second angle detection member 36.
The angle setting surface 36a and the side 52 of the glass 50 match, and the angle formed by the angle setting surface 36a and the angle setting surface 26a matches the angle formed by the side 52 and the side 53 of the glass 50. At the same time, in the state shown in FIG. 3, since the reference surface 7a of the reference position member 7 constituting the reference position determining means and the side 51 of the glass 50 match, the angle setting surface 36a and the reference surface 7a are formed. The angle formed by the sides 51 and 52 of the glass 50 matches, and the angle setting surface 26a
The angle formed by the reference surface 7a and the angle formed by the sides 53 and 51 of the glass 50 match. At this time, the reference position member 7 constituting the reference position determining means
If the reference surface 7a and the side 51 of the glass 50 do not completely match, or if the reference surface 7a and the side 51 are similar shapes that completely match, the spring 9a will be displaced within the range of the allowable error. , absorb it.

When the rear quarter window glass 50 as a polygonal member shown in FIG. 3 is placed on the set base 1 with the back surface 50b facing upward, the reference position member 7 constituting the reference position determining means is When the surface 7a is moved toward the notch 1a side and stopped at the set elongation amount, and the right side first angle detection element and the left side second angle detection element are operated, the right side angle detection element constituting the right side first angle detection element is moved. The amount of extension of the first piston rod 15 or the amount of extension of the second left piston rod 45 constituting the second left angle detection element will be different from the set value. In this case, similarly to the former case, the upper surface of the rear quarter window glass 50 as a polygonal member is
a, or it is judged to be non-standard.

Therefore, by determining this condition,
It is set on the front surface 50a or back surface 50b of the glass 50 and a specific location on the set base 1, and its positioning can be performed.

In this way, in the polygonal member positioning device of the above embodiment, the actuator 4 moves the base driving member 6 along the upper surface of the set base 1 on which the glass 50 as the polygonal member is placed. a reference position determining means for two-dimensionally abutting a specific first side of the glass 50 to move the reference position member 7; a right side first angle detection element 16 that is disposed line-symmetrically with respect to the perpendicular line and abuts the second side of the glass 50 two-dimensionally at an angle that is line-symmetrically with respect to the perpendicular line;
and a left first angle detection element 26 that two-dimensionally abuts the glass 50 with the second side on the back side;
Further, a right side second angle detection element 36 two-dimensionally contacts the third side of the glass 50, and a left side second angle detection element 36 two-dimensionally contacts the third side of the back side of the glass 50. The two-side position determining means is comprised of an element 46.

Therefore, by reciprocating the reference position determining means, it is possible to determine the hypothetical reference position of the polygonal member such as the glass 50 and obtain the angle of the specified position, that is, the inclination of the side. can. Then, by the two-side position determining means at two positions that detect mutually symmetrical angles, it is possible to determine the front and back sides of the polygonal member from the inclination of the identified sides, and to position the polygonal member that has been determined to be front and back. .

Note that the reference position determining means for determining the reference position of the polygonal member by reciprocating movement in the above embodiment reciprocates the piston rod 5 by the actuator 4, thereby causing the base driving member 6 to move along the upper surface of the set base 1. Although the reference position member 7 is moved, when implementing the present invention, any means capable of displacing the reference position of the polygonal member to a specific position may be used. However, as in this embodiment, the reference surface 7a and the side 51 are connected by the spring 9a.
In the case of a similar shape in which the reference plane 7a and the side 51 do not completely match, the spring 9a is displaced within the range of the allowable error and can absorb it. . By setting this tolerance range, it is also possible to control the quality of polygonal members.

Further, the two-side position determining means at two positions, which are independently arranged on both sides of a line perpendicular to the reference line of the reference position determining means of the above embodiment and detect mutually symmetrical angles, are the first right actuator 14 and the first right angle detecting means. A right side first angle detection element composed of a member 16, a right side second actuator 34, and a right side second angle detection member 3.
6, the left side first actuator 24 and the left side first angle detection member 2;
6, and a second left angle detecting element including a second left actuator 44 and a second left angle detecting member 46. The two-side position determination means in two directions that detect mutually symmetrical angles are composed of two reciprocating actuators that reciprocate in the orthogonal directions. Therefore, the angle of the polygonal member can be easily detected by the reciprocating position, and the front and back sides can be accurately and easily determined and positioned.

However, when implementing the present invention, the two-side position determining means at two positions that detect mutually symmetrical angles may be two reciprocating actuators disposed at angles less than orthogonal. . In this case, each two-side position determining means can be set compactly.

[Effects of the Invention] As described above, the polygonal member positioning device of the present invention includes a reference position determining means that determines the reference position of the polygonal member by reciprocating movement, and a line perpendicular to the reference line of the reference position determining means. and two-side position determining means arranged independently on both sides of the reference position member to detect mutually symmetrical angles. The right side first angle detection element or the polygonal member that is disposed line-symmetrically and two-dimensionally abuts the second side of the polygonal member at angles that are line-symmetrical with respect to the perpendicular to the back side of the polygonal member The contact state of the polygonal member with the second side is determined by the left first angle detection element that two-dimensionally contacts the second side.
Also, at the same time, a right side second angle detection element that two-dimensionally abuts the third side of the polygonal member or a left side second angle that brings the polygonal member two-dimensionally abuts the third side of the back side. A state of contact with the third side of the polygonal member is obtained by the detection element. In this way, by determining two positions that detect mutually symmetrical angles, it is possible to determine the front and back sides of the polygonal member from the inclinations of the second and third sides specified above, and to determine the position of the polygonal member that has been determined to be front and back. This is what we do.

Therefore, by reciprocating the reference position determining means and the two-side position determining means at two positions for detecting a pair of symmetrical angles, it is possible to determine whether the polygonal member is front or back based on the inclination of the identified sides. The polygonal member can be positioned.
