Abstract

PURPOSE:To continuously process plate materials of various sizes by operating sideward shifting guides from both sides of a processed plate material stopped by a stopper to correct the material in a designated condition. CONSTITUTION:In the case where a glass plate 16 is transported in an inclined state (Fig. A), though the glass plate 16 is brought into contact with a stopper 58 and stopped at a designated speed not to impose load thereon, as the glass plate is not brought into contact with a stopper 56, conveyers 50, 52 continue to move. When the glass plate is put into the parallel state as shown in Fig. B, the glass plate 16 is brought into contact with the stopper 56, and stopped by the stoppers 56, 58. At this time, it is ckecked by sensors 60 and 62 that the glass plate 16 is stopped in parallel, and a conveyer control portion stops the conveyer belts 50, 52. As shown in Fig. C, sideward shifting guides 64, 66 are shifted sideward to center the glass plate 16. Thus, material of various sizes can be centered to facilitate the operation of the next process.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a plate-shaped material fixed position stopping device for stopping a plate-shaped material processing line, particularly a plate-shaped material extracted from the processing line, at a predetermined position and in a predetermined state. .

[Technical background of the invention and its problems]

For example, plate-shaped material processing lines that process plate-shaped materials, such as liquid crystal panel production lines, thermal head production lines, photomask production lines, and print 1 substrate production lines, are used to input plate-shaped materials into the process. It consists of a system, a processing line, and a system for storing the processed plate material. Conventionally, in a system for storing processed plate-like materials in such a plate-like material processing line, the processed plate-like materials are stored in storage cassettes using a robot. Therefore, the plate-shaped material extracted from the processing line for use with the robot always needs to be stopped in the same state and at the same position.

For this reason, guides were installed in the processing line to prevent the material from meandering, and stoppers were installed on the unloading conveyor connected to the processing line that receives the processed material, so that it always stopped in the same state and at the same position.

However, when the guide is provided in the processing line as described above, the size of the plate-shaped material that can be processed is limited. Therefore, when changing to a different size material, the line had to be stopped and adjusted.

[Purpose of the invention]

This invention was made to solve the above problems, and there is no need to provide a guide in the processing line.
It is an object of the present invention to provide a fixed position stopping device for plate-shaped materials that can continuously process plate-shaped materials of any size.

[Summary of the invention]

That is, the plate-shaped material fixed position stopping device according to the present invention has the following features:
The material is corrected to a predetermined state by moving the width adjustment guides from both sides of the processed plate material stopped by the stopper.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an outline of a plate-like material processing line, which is roughly divided into three parts: a loader (group), a processing line (U), and an unloader (dan).

A loader (dish) loads glass plates (16) one by one from a lot (18) in which a plate material (e.g. glass) (16) and a mount are alternately sandwiched together, while removing the mount.
This is what is supplied to (Kun). In this case, a glass plate (16
) are attracted to the suction pad of the orthogonal transfer robot (20) and are transferred one by one from the lot (18) to the carry-in conveyor (22) of the loader connected to the processing line (dan). Figure (B) shows its movement trajectory. In addition, this loader (rule) has a loft conveyor (24) that moves as shown by the arrow in Figure (A), and this conveyor (20) automatically moves when the lot (18) becomes empty. The next standby loft (26) is supplied automatically.

The unloader (Moon) stores the processed glass plate (16) removed from the processing line (Kon) into the storage cassette (28). In this case, the unloader (Dan) is the processing flow glass plate (16) pulled out from the processing line (Kon).
, the unloading conveyor (3) connected to the processing line (U-)
0) and is always stopped at a constant position and constant state by a fixed position stopping device (32). Then, the glass plate (1) is placed on the suction pad of the orthogonal robot (34).
The untreated back side of 6) is sucked and moved to the storage cassette (28) and inserted and stored therein. Figure (C) shows its movement trajectory. Also, like the loader (Dan), this unloader (Dan) also has a cassette conveyor (36) that moves like an arrow.
) when the cassette (28) is full or the glass plate (16)
When the number of sheets reaches a predetermined number, the next standby cassette (38) is automatically supplied.

The plate-shaped material processing line as described above is controlled by a control section (not shown). A block diagram of this plate-shaped material processing line is shown in FIG. Here, the control unit (40) includes an operation panel, CPU, memory, I, 'O, etc., and contains the operation program for this line stored in the memory in advance, and the input glass plate (16) size and Based on the data on the number of sheets, the robot body (2o) and (3o)
4), lot conveyor (24), cassette conveyor (
36), an incoming conveyor (22), and an outgoing conveyor (3
control each block such as o).

The above plate-like material processing line shows the case where there is only one processing line, and if subsequent lines (for example, exposure line, post-processing line, etc.) are added, the above-mentioned An unloader like this can also be used as a loader by operating in reverse.

That is, the glass plates (16) are taken out one by one from the storage cassette (28) in which the set glass plates (16) are stored and supplied to the processing line. In this case, the fixed position stop device (32) may not be provided.

FIG. 3 shows an unloading conveyor on which the above-mentioned localization @ stop device (32) is formed, and the processed glass plate (16) extracted from the processing line (line) is supplied from the left side in the figure. The racks are placed on the conveyor belts (42) and (44) and transported. In this case, the conveyor speed is set to be faster than the conveyor speed of the processing line (kun), so that the glass plate (1
6) Prevents rear-end collisions. This conveyor belt (42
) and (44) are controlled by a conveyor control section (not shown) which operates according to instructions from the control section (40). This conveyor control section detects the glass plate (16) using an edge sensor (not shown) provided between the processing line (U-) and the conveyor (technique) and controls the motor (46).

The glass plate (16) is further conveyed to a fixed stop device (32) on conveyor belts (50) and (52) driven by a motor (48). In this case, the glass plate (16) is ensured by the conveyor belt (50) and (5).
2), the conveyor belt (42) and (
44) because the fixed position stop device (32) side is down. The motor (48) is controlled by the conveyor control section based on the detection output of an edge sensor (54) provided at a predetermined position of the fixed position stop device (32). That is, the end of the glass plate (16) is detected and the conveyor speed is reduced to reduce the conveyance speed of the glass plate (16).

Stoppers (56> and (58)) are provided at the ends of the competition V bell I-(50) and bell (52), respectively, and the glass plate (16) is stopped by these.

The stoppers (56) and (58) each have a sensor (6
0) and (62) are provided, and the conveyor control section also controls the motor (48) based on the detection outputs of these sensors (60) and (62). In other words, the crow plate (
16) comes into contact with both the stopper (5G) and (58), the motor (48) is stopped and the conveyor belt (50
) and (52) are stopped. Then, the width adjustment kites (64) and (66) are moved from both sides of the glass plate (16) at a circumferential speed to center the glass plate (16).

That is, as shown in FIG. 4, the fixed position stop device (32) has an umbrella screw (72) attached to the main shaft (1o) of the pulse motor (68) at the center position below the conveyor belts (50) and (52). installed. And this umbrella is nice 7
2), meshing bevel screws (74) and (76) are attached to the externally threaded shafts (78) and (80), respectively. That is, the rotation of the main shaft (70) of the pulse motor (68) is transmitted to the shafts (78) and (80) perpendicular to the main shaft (70) as rotations in opposite directions. And this shaft (78) and (
80) are passed through the female threads of the width adjustment guides (64) and (66)', respectively. That is, the shaft (78
) and (80), the width adjusting guide (64) is rotated.

Although not particularly shown, this fixed position stop device (32) has a limit 1 switch for detecting the origin, which is used to set the initial position of the width shifting guides (64) and (66). It will be done.

The fixed position stop device (32) with such a configuration is shown in FIG.
) Assume that the glass plate (16) is transported in an oblique state. This oblique glass plate (16
) can be stopped by contacting the stopper (5° 8) at a predetermined speed that does not apply a load to the glass plate (16), but since it does not contact the stopper (56), the conveyor belt 50) and (52) continue to move.

That is, the glass plate (16) that is in contact with the glass plate (1G) slips and does not move, but the glass plate (16) on the conveyor belt (50) side is conveyed by the conveyor belt (50). Then, as shown in FIG.
) and (58), the glass plate (16) is stopped.

At this time, the sensors (60) and (62) provided on the respective stoppers (56) and (58) check that the glass plate (16) has stopped and is parallel, and the conveyor control unit is activated. Stop the conveyor belts (50) and (52). Then, as shown in FIG. 3C, the width adjustment guides (64) and (6G) are moved from both sides to center the glass plate (16). in this case,
The amount of width adjustment is determined by the control section (40) based on the size of the glass plate (16) whose data is inputted in advance.

That is, by processing the width of the glass plate (16) to be processed in advance using software and positioning it by driving the motor (68) with a pulse signal, objects of different sizes are continuously processed and determined at a predetermined position. .

Therefore, materials of any size can be accurately centered, making it easier to move them to the next process or storing the cassette.
