[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plate glass carry-out device in a vertical polishing machine for polishing the four edges of a plate glass.

[0002]

[Prior art]

 Conventionally, when polishing the edges of four sides of a plate glass with a vertical polishing machine, the plate glass mounted on the loading pallet is obtained and placed in the left end of the vertical polishing machine.

The plate glass put into the left end of the vertical grinding machine runs toward the right end by the conveyor, and at the same time, the lower edge is ground by a rotating grindstone during the running.

When the plate glass after polishing arrives at the right end of the vertical polishing machine, it is manually picked up and rotated by 90 degrees and supplied to the left end of the vertical polishing machine.

By repeating the above process, the edges of the four sides of the plate glass are polished, and the polished plate glass that has arrived at the right end of the vertical polishing machine is manually picked up and mounted on the pick-up pallet.

[0006]

[Problems to be solved by the device]

 According to the above-mentioned polishing procedure, since the plate glass reaching the right end of the vertical polishing machine is obtained and carried to the left end of the vertical polishing machine, two workers are required on the loading side and the picking side. For this reason, there has been a problem that labor costs are significantly increased.

Therefore, an object of the present invention is to provide a plate glass unloading device that does not require an operator on the pick-up side.

[0008]

[Means for Solving the Problems] In order to solve the above problems, the present invention conveys a sheet glass in a state of being leaned by an outward transport path, and guides one side of the forward transport path. In a vertical grinding machine that receives the back surface of the sheet glass by the device and also grinds the lower edge of the sheet glass with a rotating grindstone in the middle of the sheet conveying path, it faces the sheet glass surface of the sheet conveying path. The front side of the flat glass in a posture leaning to the side is installed side by side with the backward guide path for receiving and conveying by the slide guide device, and on the forward side conveyor path just before the end of the forward side conveyor path. A configuration is adopted in which a delivery device is provided so as to supply the sheet glass of No. 2 to the above-mentioned backward path.

[0009]

[Action]

 Sheet glass in a posture of leaning by hand is supplied to the base end portion of the forward path.

The flat glass in a leaning posture on the forward transportation path is transported by the sliding guide device while receiving the back surface, and the lower edge of the glass in transit is polished by a rotary grindstone.

The plate glass after polishing is directed to the extreme end of the forward side transport path.

When the sheet glass arrives just before the extreme end of the going-side transport path, the sheet glass is received by the waiting delivery device, and the sheet glass is delivered to the base end of the backward-side transport path.

The sheet glass in a leaning posture, which has been transferred onto the base end of the backward conveying path, is conveyed while receiving the surface by the sliding guide device, and the sheet glass reaching the extreme end of the backward conveying path is manually taken. Along with lowering, it is swirled 90 degrees (so that the next polishing edge is lower), and is supplied onto the base end of the forward side transport path.

【Example】

 Hereinafter, an embodiment according to the present invention will be described with reference to the accompanying drawings.

A shown in FIGS. 1 and 2 is a well-known vertical polishing machine.

Polishing of the lower edge of the plate glass a supplied in the leaning posture by the vertical grinding machine A is performed on the upstream roller conveyor 2 (driving each roller) which forms the forward transport path 1. When the sheet glass a is supplied to the sheet glass, the lower part of both front and back sides of the sheet glass 3a is picked up and received by the two-way middle-flow belt conveyor 3 with the next outgoing side facing each other, and the sheet glass 3a is conveyed and then the downstream roller conveyor 4 Each roller is driven) and conveyed, and while being sandwiched by the above-mentioned midstream belt conveyor 3 and conveyed, the lower edge of the plate glass a is ground by the rotating grindstones 5 arranged in series.

The plate glass a conveyed in a leaning posture is adapted to receive one side of the outward conveyance path 1, that is, the back surface of the plate glass a by the sliding guide device 6.

The sliding guide device 6 includes a frame 7 having a partition shape, and a rotor 8 which is multi-stepped on the frame 7 and which is supported on the entire length of the frame 7 at a predetermined interval. There is.

Further, on one side of the forward side transport path 1, that is, on the surface side of the glass sheet a, a backward side transport path 9 parallel to the entire length of the forward side transport path 1 is provided. In the case of the side conveyance path 9, a roller conveyor 10 of the type in which each roller is driven is used in the illustrated case, but a belt conveyor may also be used.

A slide guide device 6 similar to the slide guide device 6 of the forward conveying path 1 for receiving the surface of the glass sheet a is provided on the entire length of one side of the backward conveying path 9.

Further, a delivery device 11 for supplying the plate glass a on the forward transport path 1 to the base end portion of the backward transport path 9 is provided in front of the extreme end of the forward transport path 1. .

In the illustrated case, the delivery device 11 has two left and right swinging members whose lower end is rotatably supported via a pin 12 below the forward-side transport path 1 and the backward-side transport path 9. The moving body 13, a connecting member 15 whose both ends are rotatably connected to the upper ends of the two oscillating bodies 13 via pins 14, and a supporting member 16 is installed and the tip end is rotatably connected to one of the oscillating bodies 13. It is provided between the first cylinder 17, the pillar member 18 whose lower end is rotatably supported via the pin 14 on the backward conveying path 9 side, and the upper and lower sides of the front surface of the pillar member 18 facing the back surface of the plate glass a. A plurality of stages of suction cups 19, a second cylinder 21 which is installed on a stand 20 standing upright from the connecting member 15 and whose tip is rotatably connected to the pillar member 18, and a pillar member 18 which returns to the retracted standby position are housed. With the cutout portion 22 provided on the frame 7, When the ground plate a of the lower side edge reaches the extreme end of the forward transport path 1, the first cylinder 17 contracts to rotate the rocking body 13 counterclockwise in FIG. . Then, the column member 18 moves forward in the left direction in FIG.

At this time, since the suction cups 19 that come into contact with the back surface of the plate glass a are immediately sucked through connecting hoses (not shown) or the like immediately after the advance of the column member 18, the plate glass a is adsorbed.

Then, the plate glass a held on the pillar member 18 via the suction cup 19 is received from the forward side conveying path 1 as the pillar member 18 moves forward, and is transferred toward the backward side conveying path 9, By the extension action of the second cylinder 21, the pillar member 18 is tilted in the direction of the frame 7 of the backward passageway 9, and the rotor 8 is caused to have the surface of the sheet glass a.

After that, the suction inside each of the suction cups 19 is released, and the plate glass a is delivered onto the backward-side transport path 9.

The column member 18 after the delivery of the plate glass a is caused by the contracting action of the second cylinder 21 and is retracted to the standby position by the extending action of the first cylinder 17. It may be delivered by a clamp device (not shown) or the like that slides in the direction.

The suction of the plate glass a by the suction cup 19 is performed, for example, by detecting the conveyance speed of the plate glass a, the bisector between the front and rear edges of the plate glass a in the conveyance direction is aligned with the center of the suction cup 19, and the suction is performed. The first cylinder 17 may be contracted so as to do so.

The glass sheet a transferred onto the backward conveying path 9 is conveyed, and the glass sheet a reaching the extreme end side of the backward conveying path 9 is manually taken down and swung 90 degrees forward. It is supplied to the base end of the row-side transport path 1.

As shown in FIG. 4, an arm 32 having a rotation support shaft 31 is projected from the lower portion of the pillar member 18, a receiving roller 33 is provided at the tip of the arm 32, and the third roller is installed. When the front end of the cylinder 34 is rotatably connected to the arm 32, the lower end of the plate glass a until it is delivered by the receiving roller 33 that is stopped by the extension action of the third cylinder 34 is received to receive the plate glass. When the third cylinder 34 is made to contract after the delivery of a and the receiving roller 33 is lowered together with the arm 32, it is possible to avoid the lower edge of the glass sheet a and the receiving roller 33 from being caught when the column member 18 retreats.
