Reference numeral 1 denotes a glass chamfering device, the glass chamfering device (1) is a plurality of parallel installation side by side, in Figure 1 of the present invention shown in a structure in which four glass chamfering devices (1) are installed in parallel Also, the glass chamfering device of the first and second glass chamfering device of the first to fourth glass chamfering device is adjacent to each other, and the glass chamfering device of the third and fourth are adjacent to each other.

Each of the first and second glass chamfering devices and the third and fourth glass chamfering devices has a structure in which the glass (W) is supplied from two belt supply lines (2).

Supplying the glass (W) to the glass chamfering device (1) 1 and 2 of the two belt supply lines (2) is short in length, glass (W) to the glass chamfering device (1) 3 and 4 Supplying a long length is installed.

Each of the belt supply lines 2 has a structure in which two rows of belts 21 are rotated by pulleys. One of the two pulleys in which both ends of the belts 21 are extended receives power from a motor. The belt is rotated, and the interlocking pulley on the other side is installed in a structure interlocked by a rotating belt.

1 to 4 glass chamfering device (1) of the present invention are all configured in the same structure. Therefore, in the present invention will be described as an embodiment 3 or 4 glass chamfering device (1).

First, the glass W supplied to the belt supply line 2 is transferred to the belt transfer line 41 by the first transfer unit 3.

Referring to the structure and operation of the first transfer unit 3 as follows.

The glass W supplied to the belt supply line 2 is operated by a stop air cylinder 31 which operates by receiving a signal from a detection sensor (not shown) installed in the belt supply line 2, and the piston appears downward. It is operated by the stop rods 311 formed at its lower end to stop in place.

When the glass W stops at the correct position by the operation of the stop air cylinder 31, the first lift air cylinder 32 is operated to make the piston appear downward and operate horizontally at the tip of the piston. The supply vacuum suction port 33 attached to one side of the bottom of the plate attached is lowered to vacuum the upper surface of the glass (W), and thus the supply vacuum suction port 33 vacuums the glass (W). When adsorbed, the first lifting air cylinder 32 immerses the piston upward, so that the supply vacuum suction hole 33 moves the glass W upwards (see FIG. 3), and then the first transfer. Air cylinder 34 is a sliding rod (35) and guide rod (36) to the belt transfer line (41) by moving a predetermined distance quickly toward the side stops and then restarts the piston to appear downward operation Supply vacuum suction port 33 To put down the glass (W), which is a vacuum suction on the belt entry end of the conveying line 41 (see Fig. 4)

On the other hand, the first conveying air cylinder 34 of the first conveying unit 3 is attached to a cable bearing (cableveyor: 37) to avoid twisting a plurality of air hoses (not shown) for supplying air, The cable bearing 37 moves together as the first transfer air cylinder 34 moves forward and backward.

As described above, when the first transfer device 3 transfers the glass W to the entry end of the belt transfer line 41, the belt transfer line 41 rotates to transfer the glass W to the advance end side. However, a stopper 42 for stopping the glass W is attached to the advance end of the belt transfer line 41. When the glass W stops at the stopper 42, the belt transfer line 41 is stopped. When the alignment air cylinder 43 of the alignment device portion 4 installed at both sides of the leading end of the) actuates the piston to appear, the alignment plate 44 aligns the glass W straight. At least two alignment plates 44 are provided, and the alignment plate 44 is configured to align the glass W at all times while setting the protruding length and angle according to the shape of the glass W in advance.

When the alignment operation of the alignment device unit 4 is completed, the second lifting air cylinder 51 of the second transfer unit 5 is operated to make the piston appear downward and operate at the front end of the piston. 52 is attached to the chamfering device 6 in a horizontally extended state, and a vacuum suction port 53 for transport is provided at the bottom of the horizontal plate 52. Accordingly, when the piston of the second lifting air cylinder 51 appears downward, the transfer vacuum suction port 53 may suck the glass W aligned at the leading end of the belt transfer line 41. When the vacuum adsorption for lifting the glass W is completed, the second lifting air cylinder 51 is operated to immerse the piston upward so that the vacuum suction port 53 for transporting the vacuum is vacuum adsorbed. (W) will be lifted upwards (see Figure 6).

As described above, as soon as the second lifting air cylinder 51 lifts the glass W, the second conveying air cylinder 54 is operated to ride the sliding rod 35 and the guide rod 36. Horizontally moving toward the chamfering device 6, the glass W vacuum-absorbed by the vacuum suction port 53 for transport to the upper side of the rotating disk 61 installed in the center of the chamfering device 6. It stops in the conveyed state, and at this time, the piston of the second lifting air cylinder 51 is lowered and the glass W is placed on the rotating disk 61 and the vacuum suction for conveying is carried out. As the sphere 53 releases the vacuum, the glass W is placed on the rotating disk 61 (see FIG. 7).

After lowering the glass (W) on the rotary disk 61 as described above, the operation of the piston of the second lifting air cylinder 51 is immersed upward and the second conveying air cylinder 54 is in the original position ( The operation of returning the glass to the state before conveying the glass to the chamfering unit proceeds in turn.

Next, as described above, when the second transfer device 5 lowers the glass W on the rotating disk 61 of the chamfering device 6 and returns to its original position, it is installed vertically on the base top plate 62. The pressing air cylinder 63 is operated to lower the pressing hole 64 so as to press the upper surface of the glass W placed on the rotating disk 61. (See FIG. 9).

In the bearing coupling 65 connecting the piston of the crimping air cylinder 63 and the crimping port 64, the crimping port 64 compresses the upper surface of the glass W. When rotating, it acts to rotate together.

The rotary disk 61 is rotated by receiving the rotational power from the disk motor 66 installed on the bottom of the chamfering device 6, the disk motor 66 is a grinder to be described later on the edge of the glass (W), When grinding the lower peripheral surface is used that has the function to control the rotational disk 61 rotation speed quickly and slowly when the straight portion of the glass is ground and when the corner portion is ground. For example, the disk motor itself may be used as a servo motor or a separate inverter device may be installed to assist the rotation speed to be automatically controlled.

Next, grinder device parts 7 are symmetrically installed on both sides of the chamfering device part 6, and grinder device parts 7 on both sides are mounted on the upper end of the vertical shaft 71 fixed vertically by a bearing. The bearing case 72 is installed to be capable of rotating and lifting operation, and the vibration air cylinder 73 fixed to the upper end of the bearing case 72 has a piston connected to an upper end of the vertical shaft 71.

Therefore, the bearing case 72 vibrates up and down as the piston of the vibrating air cylinder 73 oscillates, and the vibration width is about 2 mm.

A driving motor 75 and a lead bar 76 are installed on an upper surface of the support plate 74 fixedly attached to the flange of the bearing case 72, and a wheel base 77 attached to the front end of the support plate 74. The rotary shaft 78 is rotatably provided.

The drive pulley 75a fixed to the output shaft of the drive motor 75 and the interlocking pulley 78a fixed to the upper end of the rotary shaft 78 are addressed by a belt 75b, and a grinder is disposed at the lower end of the rotary shaft 78. 79 is condensed.

Both grinders 79 provided on each of the grinder device parts 7 on both sides that are symmetrically installed on both sides of the chamfering device 6 are arranged so that they can grind the upper and lower peripheral surfaces of the glass W. It is installed symmetrically.

On the other hand, on both sides of the upper surface of the base upper plate 62 of the chamfering device 6, two relaxing air cylinders 67 are installed in a symmetrical state with each other, and the pistons of the two relaxing air cylinders 67 are opposite to each other. During the emergence operation toward the direction, push the upper end of the lead bar 76 of each side grinder device portion 7 so that both grinders 79 are separated from the glass W fixed to the rotating disk 61. On the contrary, when the pistons of the two-side relaxation air cylinder 67 are immersed in operation, both grinders 79 gather toward the glass W in the rotating disk.

The operation of gathering the grinders 79 on both sides toward the glass W of the rotating disk 61 is performed by the weight axis 8.

That is, the weight (8) is inserted through the lower end of the hollow tube 82 symmetrically vertically installed on both sides of the chamfering device 6, the other end of the wire 81, one end is tied to the upper end thereof The roller 83 is connected to the tip of the support plate 74 or the wheel base 77 of the grinder device 7 on the opposite side. Therefore, the weight (8) is to always pull the grinder device portion 7 toward the rotation disk 61 by the weight of its own, at this time symmetrically installed on both sides of the base top plate 62 of the chamfering device (6) In the state where the piston of the relaxation air cylinder 67 appears and pushes the lead bar 76, the grinder 79 of each of the grinder device portions 7 on both sides is spaced apart from the rotation disk 61. When the piston of the relaxing air cylinder 67 is immersed in operation, the both side grinder device 7 rotates toward the rotation disc side while the weight 8 is pulled by its own weight so that both grinders 79 In contact with both edges of the glass (W) fixed to the rotating disk 61, the glass (W) is in a state of rotating by the rotation operation of the disk motor (66). Accordingly, one of the grinders 79 on both sides contacts the upper peripheral surface of the glass W while the other grinder contacts each of the lower peripheral surfaces of the opposite side and rotates by receiving power from the simultaneous driving motor 75. As a result, chamfering processing of the upper and lower peripheral surfaces of the glass W is performed. At this time, the vibrating air cylinder 73 of the grinder device unit 7 is operated to repeat the appearance of the piston continuously. The grinder 79 on both sides of the chamfering processing is performed smoothly while the grinding operation is performed while simultaneously rotating up and down.

As described above, both side grinders 79 of both side grinder device parts 7 are chamfered while the rotating disk 61 of the chamfering device 6 rotates the glass W one time, and the glass W is After the one-turn operation is completed, the loosening air cylinder 67 of the chamfering device 6 is operated to push the upper end of the lead bar 76 of the grinder device 7 with a piston that appears to operate. ) Is to overcome the weight of the weight (8) and to rotate in the outward direction away from the rotating disk 61 with the vertical axis (71) as the starting point, both grinders (79) are spaced far from the glass (W), As such, when the grinder 79 is relaxed in the glass W, the pressing air cylinder 63 of the chamfering device 6 is operated to immerse the piston upward. (W) Relax upwards from the top.

As described above, when the chamfering of the edge is completed and both grinders 79 and the pressing holes 64 are completely relaxed, the glass W of the rotating disk 61 of the chamfering device 6 is transferred to the conveying device part ( 9) is conveyed to the conveying conveyor (91).

A third transfer air cylinder 94, a third lift air cylinder 95 installed at a lower end of the third transfer air cylinder 94, and a lower end of the piston of the third lift air cylinder 95 It is comprised by the vacuum suction port 97 for conveyance provided in the end of the horizontal board 96 attached normally.

The operating state of the conveying unit 9 is fixed to the third transfer air cylinder 95 to the chamfering unit 6 as soon as the grinder 79 and the pressing port 64 are relaxed from the glass W. The conveyance vacuum suction port 97 reaches the upper surface of the glass W at this time.

As described above, when the conveyance vacuum suction port 97 stops above the glass W, the third lift air cylinder 95 is operated, and the conveyance vacuum suction hole 97 is operated by the appearance of the piston. The vacuum suction of the glass W causes the piston to be immersed again to lift the glass W from the rotating disk 61, and then the third transfer air cylinder 95 is operated to return to the original position and at the same time. 3 When the piston of the lifting air cylinder 5 appears and operates to release the glass W on the conveying conveyor 91 and release the vacuum of the conveying vacuum suction hole 97, the glass W is conveyed. It is conveyed to the conveyance position by 91.

The air cylinder 34 operates to lower the glass W onto the belt transfer line 41. When the belt transfer line 41 transfers the glass W to the advance end, the alignment device unit 4 operates. To align the glass W straight.

Subsequently, when the second feeder unit 5 is operated to place the glass W on the rotating disk 61 of the chamfering unit 6, the pressing hole 64 presses and fixes the glass. The piston of the loosening air cylinder 67 is immersed in operation so that the support plates 74 of each of the grinder device portions 7 on both sides rotate by the weight of the weight 8 with the vertical axis 71 as the starting point of rotation. When the 79 is in contact with each of the upper and lower peripheral surfaces of the glass (W) and rotates and vibrates up and down at the same time, the grinding operation proceeds, and when the chamfering processing of the glass (W) is completed, the conveying device unit ) To repeat the series of operations for conveying the glass (W), the chamfering process is completed to the conveying conveyor (91) to continue the chamfering of the glass continuously.
