Description

  The present invention relates to a glass substrate cassette that pays out a plurality of glass substrates mounted in multiple stages one by one or picks up a plurality of glass substrates in multiple stages.

  When handling glass substrates (for example, cutting lines in the next step, for processing to break the inserted cutting lines or chamfering the edges), cassettes should be used so that the glass substrates do not touch each other. It is necessary to enter and exit.

  Therefore, as a cassette for this purpose, a pair of opposite side surfaces of the box-shaped frame is formed by grooved side plates.

  The grooved side plate is formed by projecting multi-stage rib-shaped shelf pieces that are parallel to each other at a predetermined pitch toward the inside of the cassette.

  The reason for forming the above-mentioned shelf pieces by extension is that the robot arm is moved in and out between the left and right shelf pieces.

  And the lower surfaces of the two sides of the glass substrate picked up by the robot arm are supported (supported) by shelf pieces, and the glass substrates are accommodated in multiple stages in the cassette (for example, Patent Document 1).

  Of course, the glass substrates accommodated in multiple stages are paid out by the robot arm.

Japanese Patent No. 3366502

  By the way, the thing of the structure of patent document 1 is because the area of the shelf piece which supports a glass substrate is small in the cassette of the shelf extension type | formula with the recent enlargement of a glass substrate, Therefore The increase of the weight by enlargement is carried out. Therefore, distortion occurs in the glass substrate.

  For this reason, it cannot be used for a large glass substrate.

  Recently, in order to eliminate the occurrence of the above-mentioned distortion, there is a lifting frame (in which a wire crossing at a right angle to the paying-out direction and parallel in the front-rear direction is stretched in multiple stages, and the next processing of the glass substrate It is installed in the middle of the front roller conveyor, and the lifting frame is set on a lifting platform below the roller conveyor and used as a buffer.

  However, according to such a structure, since it is incorporated in the middle of the roller conveyor, it cannot be moved to another place as a wire cassette. In other words, even if it is attempted to move (remove) the lifting frame, the lifting platform is installed in the conveyor frame.

  Accordingly, an object of the present invention is to provide a cassette capable of picking up and discharging glass substrates in multiple stages without causing distortion of the glass substrate even if it is a large glass substrate.

  In order to solve the above-described problems, the present invention provides a cassette seat that is guided in the vertical direction on a seating material by appropriate guide means and has an opening that opens up and down. The frame has a lower edge that is supported by the outer upper edge of the opening, and at least the payout side surface and the lower surface of the two front and rear opposing surfaces, and a predetermined interval in the front and rear sides of the two left and right opposing sides of the frame. A wire cassette is formed by wires extending in a multi-stage shape, supporting each end in parallel, and above and below the seating material, so that the cassette seat and the wire cassette are not hindered from rising and falling. A configuration is provided in which a roller conveyor in which the rollers are arranged in parallel is provided, and an appropriate lifting device for moving the seat up and down at a pitch equal to the tension pitch of the upper and lower wires is provided.

  In this invention, the lower surface of the glass substrate is supported by the wire of each stage of the wire cassette, and a large number of glass substrates are accommodated in the frame.

  The lower peripheral edge of the glass substrate storage wire cassette is placed on the upper peripheral edge (upper surface) of the cassette seat.

  Under this circumstance, the cassette seat is moved down by 1 pitch together with the wire cassette by the operation of the lifting device.

  Then, the lower surface of the lowest glass substrate is received by the roller conveyor, and the received glass substrate is discharged by the driving roller conveyor.

  As described above, according to the glass substrate cassette of the present invention, the wire cassette is placed on the cassette seat, and the wire cassette is intermittently moved down by the operation of the lifting device, whereby the glass substrate on the wire is placed. The glass substrate can be discharged sequentially from the lowest position, and the glass substrate is not distorted due to the support of the parallel wires.

  In addition, if a glass substrate cassette is installed between the downstream conveyor and the upstream side, when a trouble occurs in the downstream processing machine (such as a cutting machine or a folding machine), the glass substrate being transferred from the upstream to the downstream direction. The glass substrate can be taken in multiple stages on each wire of the frame by raising the frame intermittently, and when the wire cassette is removed and the cassette seat is retracted below the roller conveyor, the glass substrate cassette The roller conveyor can also be used as a carry-in path.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  FIGS. 1 to 3 show a glass substrate cassette A according to the present invention. Reference numeral 1 denotes a seat guided on a seat member 2 in a vertical direction by an appropriate guide means 3. An opening 4 is provided in which the upper and lower surfaces are opened leaving a portion.

  In the illustrated case (see FIGS. 2 and 3), the guide means 3 is provided with rail members 6 perpendicular to the inner surfaces of the four corners of the side member 5 erected from the edge of the seat member 2. 6 is engaged with a grooved wheel 7 provided at the four corners of the seat 1.

  In addition, on the seat 1, the wire cassette B is placed with the lower surface periphery thereof supported by the upper surface periphery of the seat 1.

  The above-described wire cassette B has a frame 10 having openings 8 and 9 that are open at least on the dispensing side surface and the lower surface of the two front and rear facing surfaces except for the periphery, and both ends are supported by the two left and right facing sides of the frame 10 Are arranged in parallel with a predetermined distance between them and a wire 11 for supporting the lower surface (receiving) of the multistage glass substrate a vertically.

  Then, a large number of glass substrates a can be stored in the wire cassette B.

  In the illustrated case, the openings 8 are provided on both front and rear surfaces of the frame 10 so that the front surface is used for dispensing and the rear surface is used for picking up.

  Further, the seat 1 is moved up and down at a pitch equal to the pitch of the upper and lower tension wires 11 by an appropriate lifting device 12.

  In the illustrated case, the elevating device 12 includes male screws 13 that are erected and supported at four corners of the seating member 2 so as to be reversibly rotatable, and female screws 14 that are attached to the lower four corners of the frame 10 and are screwed into the male screws 13. And a transmission mechanism 16 composed of a gear (not shown), a rotating shaft, and a chain spanned between the sprockets of the male screw 14 by reversible operation of the first motor 15, but can be moved up and down by other transmission methods. .

  The raising / lowering is controlled such that the frame 10 is lowered by 1 pitch after being dispensed and the frame 10 is raised by 1 pitch after being taken in.

  Further, above the seating material 2, the seat 1 and the wire cassette B are not hindered from rising and falling, and are placed below the opening 4, and between predetermined wires 11 (in the illustrated case, below each wire 11. A roller conveyor 21 is provided (although arranged but not limited) (in the case of rotating rolls in parallel).

  In the figure, 22 is a transmission mechanism from the second motor 23 for reversible operation of each roller conveyor 21, and 24 is a support leg of the roller conveyor 21.

  If comprised as mentioned above, the wire cassette B is mounted on the receiving seat 1 (At this time, it positions so that the overlapping surface with the lower surface of the wire cassette B may be correctly located with respect to the upper surface receiving part of the receiving seat 1. Should be provided).

  Next, the seat 1 is intermittently lowered by 1 pitch together with the frame 10 of the wire cassette B by the operation of the lifting device 12.

  As the glass substrate a descends, the lowest glass substrate a is received on the roller conveyor 21, and then the glass substrate a on the roller conveyor 21 is discharged as shown in FIG. Is done.

  By repeating the above, the glass substrates a in the wire cassette B are sequentially discharged.

  For example, as shown in FIG. 5, the glass substrate cassette A is installed so that it can be replaced and moved in front of the cutting device X for the glass substrate a, and the discharged glass substrate a is supplied from the conveyor 31 to the cutting device X. In addition to supplying a cutting line and supplying the glass substrate a containing the cutting line to the front folding machine Y, it is interposed in the middle of the conveyor that supplies the next processing of the glass substrate a, When trouble occurs, the glass substrate a that has entered from the rear opening 8 of the frame 10 is received on the roller conveyor 21, and then the frame 10 is raised by one pitch together with the cradle 1 to receive the glass substrate a on the wire 11. The glass substrate a can be stocked in the wire cassette B by repetition.
