Description

The perception device of edge shape of plate glass in the edge-cutting machine of plate glass}

The present invention relates to a plate glass deformed chamfering machine to be able to face-face the plate glass having a free curved surface, and more particularly, the guide plate body is formed on the shaft of the fixed roller guided in contact with the plate glass At the end of the guide plate, a cable reciprocating line is connected with a sensing sensor that detects forward and backward movements so that the head can be maintained in a certain curved direction according to the curved shape of the plate glass so that the slope width can be processed uniformly. The plate glass of the plate glass deformed chamfering machine that maintains a uniform slope width by fixing the shape detection roller to 0 point by the operation of the air cylinder when the chamfering and shape detection rollers are chamfered while leaving the edge of the plate glass. A shape sensing device.

In general, the plate glass deformed chamfering machine is a variety of shapes after cutting the plate glass, such as the shape having a free-curved surface, the shape having an elliptical or square shape, the shape of a fan shape, etc. It is well known that sharp cut portions of flat glass cut into shapes have been smoothly and beautifully chamfered and polished to have a slope having an inclined shape set by a diamond wheel fixedly mounted on a motor.

However, the conventional plate glass deformed chamfering machine is a manual chamfering method of chamfering the plate glass cut into various shapes by manual operation by contacting the cutting surface of the plate glass to the diamond wheel rotating at high speed, and rotating the plate glass cut into various shapes at a constant low speed It is placed on the swivel and fixed by suction, and chamfered by rotating the driving motor with a diamond wheel on the end of the 2nd joint horizontal arm of the 1, 2 joint horizontal arms. And a pair of shape detection rollers are arranged on both sides of one axis of the diamond wheel at the bottom of the diamond wheel, and the rotation angle detection signal of the pair of shape detection rollers is sent to the servo motor. The motor rotates the two joint horizontal arms from side to side. There was a deformation of the chamfered glass to allow chamfering.However, in the case of manual chamfering by manual operation such as the former, it may be advantageous to a small amount of chamfering. As the chamfering and polishing of the chamfered surface is unbalanced, the efficiency of work on the chamfer width is unbalanced and the work efficiency is significantly lowered. The cutting part of the plate glass fixed to the upper part is closely contacted with the diamond wheel rotated by the operation of the drive motor installed at the end of the two-jointed horizontal arm, and chamfered and polished to maintain a constant slope. Could improve.

However, in the case of the automatic deformation chamfering of the glass plate as described above, the shape sensing rollers are arranged on both sides of the upper part of the rotary support, so that when the shape of the cutting surface of the plate glass is detected, the shape sensing roller is guided along the cutting surface of the plate glass. When the meter is rotated, the resistance value changed at this time is detected by the server motor control drive device and the servo motor is controlled to be reversed and reversed by this detection signal, and the two-joint horizontal arm is moved according to the cutting curve to chamfer the slope. Although the chamfering was performed while maintaining a constant angle of chamfering, when processing a right angle or corner, a pair of shape sensing rollers arranged on both sides of an upper part of a rotating support were contacted along the curved cutting surface of the plate glass. In the meantime, the shape detection on the tip side is used to As it passes through frost, there is no origin fixing means of the shape detection roller at the tip part, so it rotates instantaneously about the axis of the rotational support axis, and the servo motor is rapidly rotated forward and backward to switch the two joint horizontal arms, so the width of the chamfer is narrow. In addition, the defects of the uneven chamfering and the uneven chamfering, and the two-armed horizontal arm suddenly turn direction suddenly, the defects that the processed glass plate and the diamond wheel hit the broken plate glass.

Therefore, when chamfering the edges of the plate glass as described above, the operator always keeps the chamfering state in consideration of the sudden change of direction, and when the machine reaches the edge machining position, it grabs and secures the driving motor part and then chamfers the diamond wheel to the edge. After this, it should be guided by manual operation until the initial edge of the corner, that is, the pair of shape detection rollers are in contact at the same time. there was.

In addition, a potentiometer for detecting the resistance value (change in rotation) is fixed to the lower part of the rotating support shaft to which the shape detection roller is fixed to detect the cut surface of the plate glass. Since the water supplied to the water is sprayed on the exposed potentiometer, the water penetrates and causes malfunction if it is used for a certain period of time. .

The present invention has been made to solve the above-mentioned conventional drawbacks and problems, and the main purpose of the present invention is to build a guide plate body, which is formed on the shaft of the fixed roller guided in contact with the plate glass, the shape detection roller is installed Connect the cable line connected to the sensing sensor that detects the forward and backward without using the potentiometer at the end of the guide plate and apply this signal to the servo motor.The shape detection roller is pushed by the straight reciprocating motion of the cable along the curved surface of the plate glass. The servo motor rotates forward and reverse according to the signal of the sensing sensor so that the head is always kept constant in the curved direction of the plate glass, and even if it interferes with water, it detects the mechanical movement of the cable wire and changes the direction of the machine. It aims to provide a curved shape detection device for a flat glass deformed chamfer that can extend its life.

Another object of the present invention is to provide a recess in which the inclined guide surface of the upper and lower beams is formed on the lower surface of the guide plate body in which the shape sensing roller is installed, and to install the air cylinder in the lower portion of the recess to supply air immediately after passing through the right angle or corner part. The curved shape of the plate glass deformed chamfer which prevents the plate glass from being damaged while maintaining the uniform slope width of the edge part by preventing the rapid change of the head by holding the zero point by the cylinder rod operation To provide a device.

Plate glass deformed chamfering device of the present invention that can achieve the above object is a rotating table that can be fixed by lifting the plate glass delivered in various shapes in the center of the main body, and the rotating material without interfering with the rotation axis of the rotating projecting to the upper body Plate glass that is installed at the end of joint joint horizontal arm and joint joint horizontal arm, and the head which is installed on the end of the joint joint horizontal arm and has a diamond wheel installed on the driving motor to be chamfered while rotating In the deformed chamfering machine, the bearing holder is fixed to the bottom of the diamond wheel perforated shaft and through hole, and the shaft hole is perforated on one side and the shape sensing roller is built on the other side, and a groove having a slope guide surface is formed on the bottom of the pedestal. After mounting the guide plate body, the shaft hole of the supporting base and the shaft hole of the guide plate body are aligned and fixed by the shaft The lower surface of the support fixture is equipped with an air cylinder having a cylinder rod so as to pass through a hole and be held in the groove of the guide plate to hold the zero point, and the other end of the guide plate has a straight line of the shape detecting roller. After the reciprocating motion is detected by the sensing sensor, the cable wire which can transmit this signal to the servo motor is fixed.

As shown in FIGS. 1 to 4, the swivel table 2, which can be rotated at a constant low speed by lifting and fixing plate glass cut into various shapes in the center of the main body 1 of the chamfering machine, and the swivel table 2 of A horizontal beam (4) arranged on the rotor wheel without interfering with the rotating shaft (3), and a one-joint horizontal arm (5) and a two-joint horizontal arm (6) sequentially arranged at the ends of the horizontal beam (4), 2 A head (7) with a diamond wheel (9) installed on the driving motor (8) is installed at the end of the articulating arm (6) so that the rotating chamfer can be carried out so that a uniform slope chamfering process can be performed along the curved surface of the plate glass. In one plate glass deformed chamfering machine, the fixed roller (11) for rotating the guide in the state in intimate contact with the plate glass cutting bent surface on the upper side of the fixed base (10) installed fixed to be located below the diamond wheel (9) It is laid in 12, but the shaft 12 has a plate glass on one side The guide plate body 13 is formed with a shape detecting roller 14 capable of sensing the shape of the cut surface to advance back and forth between the head 7 and the groove 15 formed as the inclined guide surface 16 of the upper and lower beams on the other side. Was established.

In addition, the other end of the guide plate body 13 is fixed to the cable line 17 capable of linear reciprocating motion to the reciprocating motion according to the shape detection roller 14 detection according to the chamfering direction state of the plate glass servo motor 18 ) Rotates forward and backward so that the head 7 is in contact with the curved surface of the plate glass so that the diamond wheel 9 is always maintained at a constant slope.

At this time, the front end of the cable wire 17 is fixed through the fixing bracket 19 so that between the fixed bracket 19 and the other end of the guide plate body 13, the cut surface of the plate glass and the shape detecting roller 14 are always closely attached. Coil spring 20 was installed to be detected.

On the other hand, the lower surface of the support stand 10, the cylinder rod 22 is protruded in accordance with the supply of air to the groove 15 formed in the guide plate body 13, even after the straight chamfered corners do not rotate rapidly at the end of the zero point 0 The air cylinder 21 is fixedly installed so that the diamond wheel 9 can be chamfered in a state of being held.

At this time, the lower side of the groove (15) formed in the guide plate body 13, that is, the other side of the support base 10, the cylinder rod 22 through the operation of the air cylinder 21 can be constrained to the groove (15). A through hole 23 should be installed so as to be provided.

The modified chamfering device of the present invention configured as described above is mounted on the rotating table 2 of the main body 1 in the same manner as in normal use, and the plate glass having various shapes cut to a certain size is placed on the suction switch by operating an air switch. 1,2, Joint horizontal arm (5) (6) is used to position the head (7) close to the curved surface of the glass plate and turn on the switch. The rotating table (2) rotates at a constant low speed and is installed on the head (7). The drive motor 8 is rotated to rotate the diamond wheel 9.

When the head 7 is operated to maintain the chamfering angle set at the head 7, the chamfering processing is performed by contacting the diamond wheel 9 built in the driving motor 8 with the cut surface of the plate glass.

When processing the plate glass having a free grain driven and chamfered as described above, the fixed roller 11 fixed by the shaft rod 12 of the support base 10 is in close contact with the cut surface of the diamond wheel (9). ) Guided in a state in which the slope width is kept constant, and chamfering is performed, but the curved surface of the plate glass enters the curved surface of the plate glass than the supporting position of the fixed roller 11 as shown in FIG. 5A according to the rotation direction of the swivel table 2. In the case where the shape detecting roller 14 built up in the upper portion rises upward, the coil spring 20 installed between the fixing bracket 19 and the other end of the guide plate body 13 pushes the guide plate body 13 in a straight line to prevent the cable line ( 17) pulls the entire head (7) forward by the detection sensor that detects the linear reciprocating motion of the cable line (17) to pull the entire head (7) in front of the diamond wheel (9) State oil When chamfering work is to be in contact with the surface, as shown in Fig. 5b, when the shape detection roller 14 is positioned so that the support position and curved surface of the fixed roller 11 that is in contact with the plate glass to rotate the guide is positioned horizontally When the cable wire 17 is pushed in a straight line while pushing the coil spring 20 to some extent by pushing the shape detecting roller 14 formed on the plate 13, a detection sensor that detects a linear reciprocation of the cable wire 17 is detected. The servo motor 18 is operated by the signal so that the whole head 7 stays at the intermediate position where the zero point guide rotation, so that the diamond wheel 9 is in optimal contact with each other, and the chamfering operation is performed as shown in Fig. 5C. Likewise, the curved surface of the plate glass rises higher than the support position of the fixed roller 11 which is guided to the cut surface having the free curved surface of the plate glass and rotates so that the shape sensing roller 14 built on the guide plate body 13 is lowered. In the case of going down, the cut surface of the plate glass pushes the shape sensing roller 14, and this force pushes the cable wire 17 while the coil spring 20 is compressed by pushing the guide plate body 13 arranged on the shaft 12 in a straight line. Therefore, by detecting the linear reciprocating motion of the cable line 17, the servomotor 18 operates the servo motor 18 to retreat the entire head 7 back to operate the diamond wheel 9 at the optimum position. Amnesty will be chamfered.

And, when chamfering the straight cut surface and the edge surface of the plate glass according to the present invention, Figure 6a is to chamfer the straight surface of the plate glass as the axial rod of the support base 10 on the plate glass straight surface in the same way as the cut surface having the straight surface ( 12) is chamfered while maintaining the same slope width in a state parallel to the shape detecting roller 14 arranged on the fixed roller 11 and the guide plate body 13 arranged in Fig. 6b is horizontal as shown in Fig. 6a. After the straight chamfering is completed, when the shape detecting roller 14 supplies air to the air cylinder 21 by a switch operation immediately before the end of the cutting plane ends, the end of the cylinder rod 22 is supported by the force of the air. While passing through the 23, it is inserted into the groove 15 formed on the lower surface of the guard plate body 13, and is kept in the state where the zero point is held. When the guide plate body 13 deviates from the straight line with the fixed roller 11, the slope of the upper and lower light beams is inclined. guide Guided to the surface 16 is fixed to the groove (15).

Therefore, since the guide plate body 13 is fixed in a state where a zero point is caught in a straight line from the shaft rod 12 of the fixed roller 11, there is no change in the linear reciprocating motion detection signal of the cable line 17. There is no rapid redirection at all because is not working.

As described above, a cable is connected to a sensing sensor that linearly reciprocates forward and backward without using a potentiometer by placing a guide plate with a shape sensing roller on the shaft of a fixed roller that contacts and guides the plate glass. After connecting the wires, this signal is applied to the servo motor, and the shape detection roller pushes the cable along the curved surface of the plate in a straight reciprocating motion of the cable line.The servo motor rotates forward and backward to detect the curved surface of the plate glass. To keep the direction constant in the direction, and even if it interferes with water, the cable wire detects mechanical linear reciprocating motion to change the direction to extend the life of the machine, and the lower surface of the guide plate body with the shape sensing roller At the bottom of the groove The air cylinder is installed to supply air immediately after passing through the right angle or corner part, so that the guide plate body is zeroed by the rod operation of the cylinder to prevent rapid change of the head to maintain the uniform slope width of the corner part and to prevent damage One very useful design to help you out.
