Description

  The present invention relates to a splitting device that splits (divides) a large-sized liquid crystal panel (for example, a TFT panel and a CF panel) into a desired size.

  There is already known a method in which a large-sized liquid crystal panel is efficiently and sequentially broken on a single line into a desired size (for example, large, large to small) during loading. For example, see Patent Document 1).

JP 2010-26267 A

  By the way, according to the method of Patent Document 1, a front edge end material (a part where the front edge part of the panel is broken), a rear edge end material (a part where the rear edge part of the panel is broken), The intermediate end materials (parts where the panel is broken) are dropped (for example, on a chute) from the breaking position and discarded.

However, when the end material falls from the split bar material at the end of splitting, it slides down while tilting due to the weight, so the end edge of the end material is facing upward, and the upper end of the split edge is facing upward It comes into contact with the terminal surface on the lower surface of the edge of the panel and then falls while sliding while contacting.
For this reason, the terminal surface is scratched and causes defective products.

  In addition, when receiving the load after transferring the panel to the downstream conveyor after folding, the terminal surface is rubbed and scratched by the tail side surface of the belt constituting the conveyor, which may cause defective products.

  Therefore, the present invention collects the split end material so that the end face is not damaged by the end material generated by the split, and also receives and carries the downstream conveyor without damaging the terminal surface. An object of the present invention is to provide a folding device that can be used.

In order to solve the above problems, the present invention is an upstream side introduction passage provided so as to carry the large format liquid crystal panel formed by two sheets of lamination, the liquid crystal panel in front of this transportable entrance road a downstream discharge passage of cutting a liquid crystal panel provided so as to unload and load receiving that bend-breaking, and the rail facing in the longitudinal direction on the left and right sides downward between the introduction passage and discharge line, slidably in the rail It is provided so that it slides in the front-rear direction by a guide on the front-rear direction ends of both left-right travel bodies and a slider that engages and slides in the front-rear direction with the left and right synchronized by the first travel means . the upstream slider and the downstream sliders, a working unit which is provided so as to respectively slide the upstream slider and the downstream sliders, the center support provided by rising from the upper surface of the inter-end center of both running body And wood, and the upstream support member and a downstream support member provided so as to be located before and after the upstream and downstream of the center support member is raised from the upper surface of the upstream slider and the downstream sliders, the upstream support member of the left and right and an upstream folding bars and downstream folding bar alone lifting downstream lifting means to the support member supporting the both ends through a liquid crystal panel upper surface pressure, the supporting the ends through the lifting means to the center support member of the left and right a holding bar abut against the top surface of the liquid crystal panel, the upstream folding bar, holding bars, suction provided respectively on the lower surface of the downstream folding bars, and intake and exhaust pore for releasing the suction, the co-crosses the middle on the side of the introduction passage , water flat material provided so as to move in the longitudinal direction by the traveling means, the liquid which is provided so as to lift the lifting function in the slider that reciprocates traveling by the traveling means across this water flat material A first cutter for top scribing the panel, and the bar member provided to reciprocally travel by the traveling means in a direction transverse to the liquid crystal panel to the front lower side of the introduction passage, so as to lift the lifting function in the pillar a second cutter for lower surface scribing of the liquid crystal panel provided on, move in the longitudinal direction by moving means between the upstream side introduction passage and the downstream side discharge passage, and provided so as to lift the lifting means the A configuration comprising a bottom receiving bar of the liquid crystal panel is adopted.

Further, a position can be adjusted in the water flat material, and to employ a structure in which a third cutter top small split for scribing the liquid crystal panel for lifting by the lifting function.

  Further, a configuration is adopted in which the upper folding bar and the downstream folding bar are moved up and down via an elevating means, and gripping claws are provided to sandwich the edge of the liquid crystal panel between the upstream folding bar and the downstream folding bar as they rise.

  In addition, a structure is provided in which a push split plate that moves up and down via lowering means is provided below the lower surface of the upstream folding bar and the downstream folding bar, and a through hole that communicates with the upper and lower surfaces is provided in the push split plate.

  As described above, according to the splitting device of the present invention, by supplying a large liquid crystal panel to the carry-in path and carrying it in, a cutting line for dropping the front end by the first cutter is formed on the upper surface of the A surface of the liquid crystal panel. After the scribing, the downstream folding bar and the holding bar are lowered to suck the upper surface of the A surface of the liquid crystal panel, a cutting line is scribed by the second cutter at the front end portion of the lower surface of the B surface of the liquid crystal panel.

Then, after moving to the lower surface of the B side of the liquid crystal panel and pressing the raised receiving bar to cut off the ear drop, the holding bar is lifted to raise the dividing edge of the liquid crystal panel, which works in this situation Since the downstream folding bar slides in the downstream direction together with the downstream slider by the means, the divided front edge end material is pulled out, and there is no contact with the terminal surface by the extracted front edge end material, which may damage the terminal surface. In other words, the cause of occurrence of defective products can be eliminated.

  Of course, the divided front edge end material is dropped and discarded because suction by the downstream folding bar is released.

  Since the front edge dividing edge of the liquid crystal panel is sucked and held by the holding bar and floats, the first traveling means travels the traveling body in the downstream direction while maintaining this state. Receive the goods.

At the time of unloading, there is no contact between the load receiving end of the carry-out path and the terminal surface formed by dividing due to suction levitation, so that the terminal surface is not damaged, that is, the cause of occurrence of defective products can be eliminated.
The same effect is obtained when the liquid crystal panel is largely divided.

  Even when the rear edge of the liquid crystal panel is folded, the above process is performed by the holding bar and the upstream folding bar, so that the terminal surface formed by the division is not damaged.

Further, since the first cutter is arranged in parallel to the horizontal member and the third cutter is arranged in parallel to the column member, it is also possible to scribe a small cutting line on the large liquid crystal panel.

  Furthermore, gripping claws are provided on the upstream folding bar and the downstream folding bar via the lifting means, and the upstream folding bar and the downstream folding bar sandwich the edge of the liquid crystal panel as it rises. The edge can be sandwiched between the bar and the gripping claws so that the edge can be folded (divided) very smoothly.

  In addition, the upstream folding bar and the lower folding bar are provided with a split plate that moves up and down via the lifting means, and the upstream folding bar is provided by sucking the edge of the liquid crystal panel to the lower surface of the split plate through the through hole of the split plate. It is possible to break by lowering the downstream folding bar, and the broken end material can move to the upstream folding bar and the downstream folding bar together with the traveling body, then release the suction and discard at the correct position. it can.

  As the elevating means 13, a system comprising a ball screw driven by a reversible operation of a motor and a female screw into which the ball screw is screwed is used.

  Further, a horizontal member 19 that crosses the loading path 1 is arranged in the upper part of the loading path 1, and both ends of the horizontal member 19 are held by a traveling body 21 that travels in the front-rear direction via the traveling means 20.

  The traveling body 21 slides with the rail 4 as a guide and employs a linear motor system as the traveling means 20, but is not limited, and may employ a male screw or a female screw system.

Then, a slider 24 that reciprocates by the traveling means 23 is provided on the rail 22 provided on the horizontal member 19, and a first cutter 26 that puts a cutting line X for a large portion or an ear portion that moves up and down by a cylinder 25 in the slider 24. Is provided.

  Further, between the carry-in path 1 and the carry-out path 2, there is provided a folding bar 29 that moves in the front-rear direction by the moving means 27 and moves up and down by the elevating means 28.

  In the case shown in the drawing, the receiving bar 29 is two in parallel before and after the upstream folding bar 14 and the downstream folding bar 16, and a split end material is formed as an integrated type with a chute 30 interposed between the parallel receiving bars 29. Although it collect | recovers, it is not limited, What is necessary is just to contact | abut to the lower surface of the B surface of liquid crystal panel A in the case of folding.

  The moving means 27 is composed of a rail 31 and a traveling carriage 33 having a slider 32 slidably engaged with the rail 31, and uses a linear motor for movement in the front-rear direction. And a female screw that is screwed into the male screw and supported by the traveling carriage 33.

  The lifting means 28 is connected to the receiving bar 29 by the cylinder supported by the chute 30, but is not limited thereto.

  Further, in front of the upstream folding bar 14, as shown in FIG. 6, a second cutter 34 for scribing an ear drop or a cutting line Y for cutting is provided between the lower side edges of the B surface of the liquid crystal panel A. .

  The second cutter 34 has a traveling body 35 arranged on a line crossing the bottom of the liquid crystal panel A, and a lower surface slider 37 of the traveling body 35 is slidably engaged with the rail 36, and the linear motor traveling means. The traveling body 35 is reciprocated by 38, the slider 41 is engaged with the vertical rail 40 of the column member 39 erected on the traveling body 35, the slider 41 is lifted by the action of the cylinder 42, and the upper end of the slider 41 is The second cutter 34 provided on the liquid crystal panel A is brought into contact with the lower surface of the B surface of the liquid crystal panel A.

  With the above configuration, by supplying the large liquid crystal panel A to the carry-in path 1 and carrying it in, the cameras P on both sides of the horizontal member 19 read the marks on the leading edge corners on both sides of the liquid crystal panel A. Then, the running body 21 is slid in the front-rear direction by the running means 20 so that the horizontal member 19 matches the scribe line, and the scribe line is positioned.

  Thereafter, the first cutter 26 is lowered by the action of the cylinder 25, and the cutting line X is scribed on the upper surface of the A surface of the liquid crystal panel A while the slider 24 is driven by the running means 23.

  Next, when the liquid crystal panel A sent out by the carry-in path 1 is stopped, the second cutter 34 is raised by the action of the cylinder 42 and the slider 37 is caused to travel by the action of the traveling means 38 so as to be placed on the lower surface of the B surface of the liquid crystal panel A.

  In the above feeding, the traveling carriage 33 is moved in the upstream direction by the moving means 27, and the receiving bar 29 is stopped at the position where the cutting line Y has passed upstream as shown in FIG.

  Accordingly, by moving only the downstream folding bar 16 by the action of the lifting and lowering means 13, the cutting lines X and Y are broken as shown in FIG.

  The front edge split end material C of the liquid crystal panel A accompanying the split is lowered while being sucked to the lower surface of the downstream folding bar 16, and the suction by the intake / exhaust holes 17 is released to pump the air. The released end material C falls on the chute 30 and is discarded.

  On the other hand, the lower folding bar 16 is lifted by the action of the lifting / lowering means 13 while maintaining the suction of the upper surface of the folding side end of the liquid crystal panel A on the lower face of the holding bar 15, and then the action of the lifting / lowering means 13 as shown in FIG. By raising the holding bar 15, the folded edge side of the liquid crystal panel A is pulled up, and while the pulling is maintained, the traveling body 3 travels in the downstream direction by the first traveling means B, and the liquid crystal panel A enters the carry-out path 2. To receive.

  At this time, as shown in FIG. 10, the terminal surface T formed in accordance with the folding of the liquid crystal panel A is pulled up while being sucked and held by the holding bar 15 and is transferred to the carry-out path 2. This prevents contact with the transfer end of the terminal and prevents the terminal surface T from being damaged.

  After the transfer, the suction by the holding bar 15 is released, and the upper surface of the A surface of the liquid crystal panel A is released from the lower surface of the holding bar 15 by the air pressure feeding to the intake and exhaust holes 17.

  In the middle of the liquid crystal panel A, as shown in FIG. 11, the cutting line X is scribed on the upper surface of the A surface by the first cutter 26 and the cutting line Y is scribed on the lower surface of the B surface by the second cutter 34. , Y are folded by the above-described action of the holding bar 15, the downstream folding bar 16, and the receiving bar 19, as shown in FIG.

  As shown in FIG. 13, the terminal side of the liquid crystal panel A is also scribed with a cutting line X by the first cutter 26 on the upper surface of the A surface and a cutting line Y by the second cutter 34 on the lower surface of the B surface. The end material C is sucked by the bar 14, and the suction is released and dropped onto the chute 30.

Of course, the liquid crystal panel A is also sliced by the second cutter 34 at the middle edge of the liquid crystal panel A, the scribed portion is broken to form the terminal surface T, and the transfer of the formed terminal surface T to the carry-out path 2 is also described above. This is done by the action of
The divided large liquid crystal panel a is unloaded by the unloading path 2 and carried out.

  Even when it is necessary to form the terminal surface T (on the lower surface of the B surface) on the terminal opposite to the carry-out path 2 of the large liquid crystal panel a (not shown), the receiving bar 29, the upstream folding bar 14, and the holding After dividing by the bar 15, the terminal side of the large liquid crystal panel a is sucked and held by the holding bar 15, and then the upstream folding bar 14 is slid to the loading path 1 side by the loading path 1 side action body 9. The end material C sucked and held in the upstream folding bar 14 is pulled out from the lower side of the terminal surface T to prevent the end material C from scratching the terminal surface T, and the suction by the upstream folding bar 14 is thereafter performed. Release the end material C to the chute 30.

  In the second embodiment of the present invention, as shown in FIGS. 3 and 4, the horizontal member 19 can be adjusted in position, and a cutting line Z for splitting is scribed on the upper surface of the A surface of the liquid crystal panel A. A third cutter 51 is provided.
