Description

  The present invention relates to an apparatus and a method for transferring a glass plate while removing the interleaf from a glass plate stacked in a vertical position with the interleaf on a pallet.

  Conventionally, when laminating a plurality of glass plates in a leaning position on a pallet, in order to prevent the occurrence of scratches or the like due to the contact between the glass plates, a cushioning material such as slip paper or powder, or a spacer, etc. Many methods and apparatuses for transferring and transferring a partition member between glass plates have been proposed and known, and each is used properly depending on the purpose and application.

For this reason, when transferring a glass plate stood on a pallet with interleaving paper to another device such as a conveyor, the interleaving paper must be removed and transferred. No. 225225 discloses a plate glass insertion device that adsorbs a sheet of glass placed on a pallet from the top of a slip sheet and transfers it to another device one by one. There is a plate glass insertion device equipped with a main suction plate that adsorbs plate glass and a sub suction plate that adsorbs slip sheets at the tip of a reciprocating swinging arm, and these main suction plate and sub suction plate operate independently. (Patent Document 1).

  Also, in Japanese Utility Model Publication No. 6-1546, in a device for adsorbing a sheet glass with a slip sheet on one side and delivering it to another place, this device includes a main suction disk for adsorbing the sheet glass from the slip sheet and this The main suction plate is equipped with a sub-suction plate for slipping paper that is attached with a common suction surface.The main suction plate and the sub-suction plate are connected to the pressure source and the vacuum pump by independent pipes, respectively. In addition, there is disclosed a sheet glass adsorption / delivery device having an interleaf removal function that performs switching between suction and air ejection independently by a switching valve provided in the middle of each pipe (Patent Document 2).

In addition, Japanese Utility Model Publication No. 7-52112 discloses that the robot installed in the X, Y, and Z directions of the robot in the vicinity of the glass plate that is stacked on the pallet together with the interleaving paper is movable and rotated in the X, Y, and Z directions. A glass plate transfer device in which a frame is mounted on a movable arm, and the front glass plate is sucked and supported by a suction pad disposed on the frame, and the lower side of the frame facing the glass plate A pressure contact member that can move toward and away from the frame and that protrudes in the direction of the glass plate is provided by a perspective movement cylinder provided in There has been disclosed a glass plate transfer device in which an adsorbing member for adsorbing, supporting and transferring an end portion of a slip sheet behind the glass plate is disposed (Patent Document 3).
JP-A-2-225225 No. 6-1546 No. 7-52112

  In Patent Document 1, only the plate glass is delivered from the main suction plate that adsorbs the plate glass from the top of the slip sheet to the suction plate provided on the moving body, and the slip sheet is sucked and separated by the sub suction plate. In addition to the two complicated configurations for delivering to the main body, there is a problem that the delivery from the main suction board to the suction board is difficult due to slight timing, inclination of the plate glass, and the like.

  Further, Patent Document 2 is based on the premise that there is a slip sheet on the front surface of the glass plate loaded on the pallet, and the front glass plate is adsorbed from the slip sheet together with the slip sheet. When the paper is removed from the pallet, it will be dragged to the glass plate being transferred, causing the slip of the interleaf to rise behind, the slippage due to the weight of the interleaf in the front row, or drooping from the upper side. There was a problem that it would hinder the transfer of the board.

  Further, the invention disclosed in Patent Document 3 requires that the slip sheet sandwiched between the glass plates stacked in a vertical posture on the pallet is arranged so as to protrude from the edge of the glass plate, and the front row. For the first time in a state where the slip sheet protruding from the edge of the glass plate is pressed by the pressure contact member for pressing the slip sheet, the frontmost glass plate is sucked up and the exposed portion of the slip sheet is sucked by the slip sheet suction member. However, not only is it necessary to stack the slip sheets so that they protrude from the glass plate, but there is also a problem that a pressure contact member for pressing the slip sheets that presses the lower end of the slipped slip sheets is required.

  The present invention has been made in view of such a problem. When a glass plate laminated in a vertical position on a pallet with a simple configuration is taken out and transferred to another position, the transfer of the glass plate enables recovery of the slip sheet. An object is to provide a loading device and a transfer method.

  That is, the present invention adsorbs a glass plate in a glass plate transfer device in which glass plates and slip sheets are alternately stacked in a leaning position on a pallet and are sequentially taken out from the front row of glass plates and transferred to a predetermined position. A main frame provided with supporting glass plate suction means and a sub-frame provided with slip sheet suction means for sucking and supporting the slip sheet at the back of the glass plate are opposed to form a parallel link. The operation of the link drive cylinder provided on the sub-frame causes the position of the glass plate adsorbed by the glass plate adsorbing means to move upward, and the lower side of the interleaf paper on the back of the glass plate is adsorbed by the interleaf adsorbing means. This is a glass plate transfer device characterized in that it is made.

  Alternatively, the present invention is the above-described glass plate transfer apparatus, characterized in that it is provided with posture changing means for changing the posture of the subframe from an inclined posture to a horizontal posture.

  Alternatively, according to the present invention, the glass plate transfer device described above is characterized in that the suction pad of the glass plate suction means is a bellows type pad, and the inclination of the main frame supporting the glass plate suction means can be absorbed. It is.

  Alternatively, the present invention provides a glass plate transfer method in which glass plates and slip sheets are alternately stacked in a leaning position on a pallet, and are sequentially taken out and transferred from the frontmost glass plate. The parallel link formed by opposing the main frame to be supported and the sub-frame to support the slip sheet adsorbing means is deformed, and the position of the glass plate on the pallet is moved up and moved by the glass plate adsorbing means. Then, there is a glass plate transfer method characterized in that the exposed interleaf sheet portion is adsorbed by an interleaf adsorbing means so that the glass plate and interleaf paper can be adsorbed separately.

  Alternatively, according to the present invention, the slip sheet adsorbing means is released and the slip sheet is collected in the hopper on the slip sheet hopper on the way of transferring the glass plate sucked and held by the glass sheet suction means to a predetermined position. This is a method for transferring a glass plate as described above.

  In the present invention, a main frame that supports the suction means for the glass plate and a sub-frame that supports the suction means for the slip sheet are connected in a parallel link structure, and the parallel link is operated so that the glass plate is slightly tilted upward. When moved, the lower end portion of the slip sheet behind the glass plate can be exposed. Therefore, if the exposed portion of the slip sheet is adsorbed by the slip sheet suction pad, especially the sandwiched between the glass plates. Even when the paper is not particularly disposed so as to protrude from the glass plate, the glass plate and the interleaf can be adsorbed and supported by separate adsorbing means, and the interleaf can be collected during the transfer of the glass plate.

  In addition, when the glass plate is raised to the extent that the lower end of the slip sheet can be sucked by the slip sheet suction pad, the slip sheet suction pad is sucked to the lower end of the slip sheet. The upper end does not bend.

  As shown in FIG. 1, the present invention comprises a plurality of glass plates G stacked on the floor rail 3a of the pallet 3 so as to lean on the back plate 3b and sandwiching the interleaving paper 2 in a leaning posture. The glass sheet G and the interleaf sheet 2 behind the glass sheet G are adsorbed and taken out by separate adsorbing means of the glass adsorbing means 10 and the interleaf adsorbing means 20, respectively, and are provided near the pallet as shown in FIG. The slip sheet 2 is transferred to the transport conveyor 50 or the like, and the slip sheet 2 adsorbed by the slip sheet suction means 20 is dropped into a slip sheet hopper (not shown) during the transfer to the transport conveyor 50 and recovered. It is the transfer apparatus of the glass plate which has the removal function.

  In the present invention, a main frame 31 provided with a glass plate adsorbing means 10 for adsorbing and supporting the glass plate G, and a subframe 32 provided with an interleaf adsorbing means 20 for adsorbing and supporting the interleaf at the back of the glass plate G. Are formed into parallelograms as opposing sides, and a parallel link 30 is formed in which adjacent frames are axially attached.

  The glass plate adsorbing means 10 is provided with a glass adsorbing pad 11 at the tip of a cylinder rod of a glass adsorbing pad cylinder 12 disposed at a plurality of locations in the center of the main frame 31. In this example, the slip sheet suction pad 21 is provided at the tip of the cylinder rod of the slip sheet suction pad cylinder 22 disposed at each of the two lower corners of the subframe 31.

  The glass suction pad 11 is pressed against the glass plate surface by the pressing force of the glass suction pad cylinder 12, but it is not excessively pressed against the glass plate surface, or the suction surface and the glass plate surface are parallel to each other. For the purpose of preventing leakage in the case of not, it is preferable to have a swing structure with a spring or a bellows type pad structure.

  The cylinder body of the link drive cylinder 33 is pivotally attached to the subframe 32 of the parallel link 30, and the main frame 31 is connected to the tip of the cylinder rod 34 of the link drive cylinder 33. The main frame 31 of the parallel link 30 moves in an oblique direction while being parallel to the sub-frame 32 and becomes accessible.

  The main frame 31 of the parallel link 30 can be moved obliquely upward by the operation of the link drive cylinder 33, and the glass plate suction means 10 is fixed to the main frame 31, and the position of the glass plate G adsorbed thereby. Can be moved away from the pallet 3 and slightly moved upward, and the lower side of the interleaf paper 2 on the back of the glass plate G can be exposed. The slip sheet suction pad 21 of the suction means 20 can be sucked so that the glass plate G and the slip sheet 2 can be sucked separately.

  In addition, when the posture of the sub frame 32 needs to be changed from an inclined posture substantially parallel to the glass surface on the pallet 3 to a horizontal posture, the posture of the main body of the transfer device 1 can be changed as posture changing means 40 that can change the posture. The posture change cylinder 41 is pivotally attached to the arm 4, and the cylinder rod 42 of the posture change cylinder 41 is pivotally attached to one end portion of the sub frame 32.

  The plurality of suction pads 11 of the glass plate suction means 10 are connected to a vacuum generator (not shown) by an air tube or the like, while the slip sheet suction means 20 is for sucking the lower end side of the rectangular slip sheet 2. Similarly to the glass plate suction pad 11, the suction pad 21 is connected to a vacuum generator (not shown) by an air tube or the like.

  Next, using the transfer device 1 of the present invention, the operation procedure in the case where the glass sheet G is taken out from the pallet 6 together with the interleaf paper 2 and transferred to a conveyor or the like will be described in detail.

  As shown in FIG. 1, a plurality of flat glass plates G are stacked on the floor rail 3 b of the pallet 3, and the slip sheet 2 is sandwiched between the glass plates G, G,. It leans so as to lean on the back plate 3b.

  With a sensor (not shown), the suction surface of the glass plate suction pad in a state where the cylinder rod of the link drive cylinder 33 is extended to be a set distance close to the front glass plate surface of the glass plates stacked on the pallet, When the glass suction pad cylinder is operated so that the glass suction pads 11, 11,... Project toward the glass surface, the glass suction pad is pressed against the frontmost glass plate surface, and the bellows portion is compressed and deformed. The glass plate is adsorbed by an adsorption pad.

  Next, when the link driving cylinder 33 is operated to operate to return the protruding cylinder rod, the main frame 31 moves obliquely upward at the same time as it leaves the pallet due to the parallel link structure, so that it is fixed to the main frame. The glass plate G moves slightly upward obliquely by the suction of the glass suction pad attached to the tip of the rod of the glass suction pad cylinder.

  Since the lower end of the interleaf paper 2 immediately behind the glass plate G is exposed when the glass plate G is slightly moved obliquely upward, the interleaf slip adsorbing pad cylinder 22 is exposed to the exposed portion of the interleaf paper 2. , The cylinder rod 23 is extended, and the slip sheet 2 is sucked by the slip sheet suction pad 21.

  Further, after the slip sheet adsorbing means 20 is operated, the glass plate G is further raised as indicated by an arrow, and the cylinder rod 23 of the slip sheet suction pad cylinder 22 is returned to the slip sheet 2 and the glass plate G. Are adsorbed and held separately.

  Further, the arm 4 that supports the adsorbed glass plate G is moved to the position of the conveyor 50 in the horizontal direction by a conventionally known horizontal moving means (not shown). Since only the sides are sucked and held by at least two slip sheet suction pads 21, the slip sheet is moved in a cantilevered state, and a slip sheet hopper (not shown) provided between the pallet 3 and the transport conveyor 50 is provided. When the predetermined position is reached, the slip sheet suction pad 21 releases and releases the slip sheet 2 to allow the slip sheet 2 to fall naturally into a slip sheet hopper (not shown) and to return the origin of the slip sheet suction pad cylinder 22. .

  After dropping the interleaving paper 2 into an interleaving paper hopper (not shown), the adsorbed glass plate G is further transferred from the pallet 3 to the transporting conveyor 50 by the conventionally known horizontal moving means (not shown). Then, the attitude changing cylinder 41 attached to the arm 4 is operated to change the attitude of the glass sheet G from the inclined attitude to the horizontal attitude together with the subframe 32.

  After moving the glass plate G to a predetermined position on the upper portion of the conveyor 50 and then lowering the arm 4 by a conventionally known lifting means (not shown), the adsorbed glass plate G is lowered to the upper surface position of the conveyor 50, After the glass plate G is placed on the transport conveyor 50, the glass suction pad 11 is released, the glass suction pad cylinder 12 is returned, and then the arm 4 is raised.

  The glass plate G transfer device located above the conveyor 50 returns the parallel link 30 such as the main frame 31 to the inclined posture, operates the link drive cylinder 33 to extend the rod, and the glass adsorbing means 10. The parallel links 30 such as the main frame 31 are returned to the pallet 3, and the transfer operation of the glass plate G from the pallet 3 to the transfer conveyor 50 is sequentially repeated.

  Although the preferred embodiment has been described above, the present invention is not limited to this, and various applications can be considered.

  The glass plate suction pad 11 may have a pad diameter determined in consideration of the weight and safety factor of the glass plate G, but the slip sheet suction pad 21 is a slip sheet exposed by the glass plate slightly moved by the glass suction pad. Since the lower end portion of the substrate may be adsorbed, a small-diameter or horizontally long adsorption pad is preferable.

  The glass plate G is a flat tempered glass plate, a semi-tempered glass plate, a single plate such as a green plate, or a plurality of tempered glasses, or an intermediate film such as PVB or EVA or a resin injection by combining tempered glass and green plate glass. The laminated glass bonded in (1) and the above glass plate with an anti-scattering resin film adhered thereto are targeted.
