Further, the base end portion of the guide rod 41 is also provided with an inclined portion 42 which is configured to easily receive the transport carriage 30 even when the receiving direction of the transport carriage 30 is reversed.

The roller conveyor 5 is provided with a horizontal positioning device 50 (position adjusting device) for holding the outer portion of the roller supporting portion 33 of the transporting carriage 30 on the diagonal line of the substrate 38, and the roller supporting portion 33, that is, the roller The roller support shaft 40 of R1 is positioned in the plane to adjust the roller conveyor 5 to the correct position. The horizontal direction positioning device 50 is a pair of clamps 51 that are formed on the diagonal line between one of the front and rear walls and the side wall on one of the diagonal lines on one of the substrates 38, and are disposed on the diagonal line of the corner portion in the same manner. 51 squeezed and clamped. The roller support shaft 40 of the roller R1, that is, the roller R1 is in the horizontal plane, positions the conveying direction of the roller conveyor 5 and the direction orthogonal to the conveying direction.

A pressing body 52 having a fitting surface 52a that abuts against a right angle of a corner surface of the extruded substrate 38 is attached to an end portion of each of the clamps 51. Further, the clamp 51 is configured to be allowed to move below the drum support portion 33 in the clamped state.

The hydraulic pressure supply device 53 is connected to each of the clamps 51, and each of the clamps 51 is moved forward and backward by the hydraulic pressure supply device 53. At this time, the position of the roller support portion 33 of the transport carriage 30 in the vertical direction is determined by the height dimension of the roller support portion 33 including the base portion 32 and the wheel 31. Therefore, in such a manner that the height position is the correct position, the height dimensions of the respective portions are set within a range in which the degree of the obstacle is not caused when the paper is to be described later. The clamp 51 and the hydraulic pressure supply device 53 constitute a horizontal direction positioning device 50.

The eighth drawing is an enlarged side view of an important part of the first figure. As shown in the eighth figure, two transport carriages 30 are disposed below the first bonding apparatus 13 while supporting the drum R1. At this time, the transport carriage 30 (first transport carriage) on the left side winds up the polarizing film sheet F wound around the drum R1, and the transport carriage 30 (second transport carriage) on the right side stands by while holding the drum R1. The roller R1 on the left side is formed to wind up the polarizing film sheet F toward the lower right side. The drum R1 on the right side is configured to temporarily take out the end of the polarizing film sheet F on the upper left side and then roll it out to the left side. An automatic paper feeder 54 is disposed between the two transport carriages 30.

The automatic paper feeder 54 is provided with a pair of opposing cut connectors 55 which are detachable from each other. A conveyance path of the polarizing film sheet F taken out from the left side roller R1 and a conveyance path of the polarizing film sheet F taken out from the standby right side roller R1 are set between the pair of cutting connectors 55.

Here, the polarizing film sheet F taken out from the right and left rollers R1 in the portion where the connector 55 is opposed is wound up. Further, the cut connector 55 (first cut connector) corresponding to the left side of the left side roller R1 is disposed at a position apart from the left side of the polarizing film sheet F of the left side roller R1. The cut connector 55 (second cut connector) corresponding to the right side of the right side roller R1 is attached to the right side of the polarizing film sheet F of the right side roller R1 so as to be sucked in the lower half of the cut connector 55. The terminal of the polarizing film sheet F is held down.

With the manufacture of the liquid crystal panel P, the amount of the polarizing film sheet F remaining on the left side roller R1 is reduced, and only a small amount is left, and the left side cut connector 55 is used to secure the paper saving fee after the polarizing film sheet F is sucked. It is cut at the center of the outline, and the terminal is held in the upper half of the cut connector 55. When the left cutting connector 55 and the right cutting connector 55 are pressed against each other in this state, the polarizing film sheet F terminal facing upward and the cutting connector 55 on the left side held by the cutting connector 55 on the right side. The terminal of the polarizing film sheet F that is held downward is overlapped to carry out the paper. In addition, in the eighth figure, the single-sided bonding panel P11 is conveyed on the roller conveyor 5.

Next, the action of the first embodiment will be described.

The liquid crystal panel P conveyed by the roller conveyor 5 is bonded to the bonding sheet F5 by the first bonding apparatus 13 to form the single-sided bonding panel P11, and secondly, the bonding sheet F5 is attached by the second bonding apparatus 17. The single-sided bonding panel P11 is bonded to the double-sided bonding panel P12. Between the first bonding device 13 and the second bonding device 17, a pair of rollers R1 interact to accept a new roll. The supply of the cylinder R1 is performed while the polarizing film sheet F is wound up, and the bonding sheet F5 is supplied to the conveyance conveyor 5 by the conveyance device 22.

When the first bonding apparatus 13 shown in FIG. 8 is taken as an example, the amount of the polarizing film sheet F remaining on the drum R1 of the left conveyance carriage 30 is reduced with the manufacture of the liquid crystal panel P, and only a small amount is left. At this time, the paper is ejected by the automatic paper feeder 54, and at this time, the polarizing film sheet F of the right side roller R1 is unwound. The transporting carriage 30 on the left side after the completion of the paper feed is moved away from the arrangement position of the drum R1 below the drum conveyor 5 on the side of the roller conveyor 5, and travels toward the drum storage area E (see FIG. 5). In the drum accommodation area E, a new drum R1 is attached to the transport carriage 30, and the transport carriage 30 including the new drum R1 moves to the drum conveyor 5 again.

When the transport carriage 30 reaches the side of the roller conveyor 5, as shown in the seventh figure, the base portion 32 of the transport carriage 30 is guided to the inclined portion 42 of the pair of guide bars 41, and approaches the guide rod 41 at the side wall 34 of the base portion 32. In the state of the guide portion 43, the transport carriage 30 is again stopped at the drum arrangement position of the left side roller R1.

Next, when the transport carriage 30 is parked, the air float device 29 is operated, and the drum support portion 33 is movable in the horizontal plane to the base portion 32 of the transport carriage 30.

Then, when one of the horizontal direction positioning devices 50 presses the corner portion of the substrate 38 of the roller support portion 33 against the pressing body 52 of the clamp 51, the air bearing device 29 becomes a roller support portion which is freely movable in the horizontal plane. 33 is positioned in the horizontal plane. Thus, the roller fulcrum 40 of the shaft of the roller R1 is correctly positioned in the horizontal plane.

Then, when the supply of air from the air supply means 35 of the air flotation device 29 is stopped in the positioning state, the air floating type ball unit 36 of the floating air floating device 29 is lowered. Therefore, the lower surface of the roller support portion 33 is grounded on the upper surface of the substrate 38 of the base portion 32, and the position of the roller support portion 33 is fixed via a fixing means (not shown) in a state where the roller support portion 33 is positioned. There is a slight difference between the height direction dimension in this state and the height direction dimension at the time of positioning. However, when considering the difference in the paper, it is not necessary to prevent the paper from being renewed when the paper is renewed.

Then, after the positioning is completed, the lower half of the disconnecting connector 55 on the left side of the automatic paper feeding device 54 sucks and holds the terminal of the polarizing film sheet F taken up from the left side roller R1, and stands by to the polarizing film sheet F of the right side roller R1. The timing of the paper feed.

According to the above embodiment, only the transport trolley 30 to which the drum R1 is mounted is required Moving below the roller conveyor 5, the drum R1 can be placed below the roller conveyor 5. Therefore, it is not necessary to arrange a rail for loading the drum R1 to the side of the drum conveyor 5, and it is possible to reduce the space portion of the arrangement rail in the arrangement space of the drum conveyor 5. Therefore, the installation space of the entire apparatus including the drum conveyor 5 is reduced, and the apparatus cost can be reduced. Further, since the rail does not protrude from the side of the drum conveyor 5 as before, there is no object in the area on the side of the drum conveyor 5, and work on the periphery of the apparatus is facilitated.

Then, the roller R1 attached to the transport carriage 30 is opposed to the base 32, and the posture of the roller support portion 33 can be changed in the horizontal plane. By positioning the roller support portion 33 with respect to the roller conveyor 5 by the air flotation device 29 and the horizontal direction positioning device 50, the direction of the roller support shaft 40 of the drum R1 can be adjusted to the correct position. Therefore, the unwinding direction of the drum R1 can be correctly adjusted, and the paper feeding operation of the drum R1 can be prevented.

Further, by using the air flotation device 29, the position of the drum support portion 33 can be freely adjusted in the horizontal plane with respect to the base portion 32 of the transport carriage 30 when the air is supplied, and the drum of the drum R1 can be adjusted by the horizontal direction positioning device 50. The fulcrum 40 is positioned relative to the roller conveyor 5 in a horizontal plane. After the positioning is completed, when the air supply device 35 is stopped and the supply of air is stopped, the roller support portion 33 can be grounded to the base portion 32. Therefore, the polarizing film sheet F can be wound up by the drum R1 in a state where the transport carriage 30 is still disposed under the drum conveyor 5.

Then, since the roller shaft 40 of the drum R1 can be positioned in the horizontal plane by simply moving the corner portions of the outer wall of the drum support portion 33 by the pair of jaws 51, the positioning time can be shortened.

In the present embodiment, for example, a case where a polarizing film is bonded to a liquid crystal panel has been described, but the present invention is not limited to the above embodiment. The member to which the film material is bonded is not limited to the liquid crystal panel, and may be applied to an organic EL panel. The film material to be bonded is not limited to the polarizing film, and may be applied to an antireflection film, a light diffusion film, or the like. Further, instead of the guide rod 41, a roller guide that is vertically rotatably supported in the axial direction may be provided.

Further, the air supply device 35 may be supplied to the base portion 32 of the transport carriage 30 by a hose from a supply air source provided in the factory. In this case, it is only necessary to use a cable bear (a cable holder, a registered trademark) that is deformed by the operation of pressing and pulling out the hose at the position of the roller R1 under the roller conveyor 5 of the transporting carriage 30, thereby ensuring piping, The connection status of the wiring type is sufficient. Then, as long as the posture of the roller supporting portion 33 is changeable in the horizontal plane to the base portion 32 of the transporting carriage 30, the roller supporting portion 33 can be positioned, and various forms can be employed instead of the air floating device 29 or the horizontal positioning device 50.

In the present embodiment, the transport carriage 30 is exemplified by the fact that the base portion 32 and the drum support portion 33 are not separated at all, but the present invention is not limited to the embodiment. After the conveyance trolley 30 reaches the lower side of the roller conveyor 5, the roller support portion 33 is positioned and fixed, and is still fixed to the roller conveyor 5 side, and is reserved, so that the base portion 32 of the conveyance carriage 30 is returned to the drum storage area. The composition of E.

Then, an embodiment in which the drum R1 stands by in order to continue the paper is described, but a single drum type can be applied to the present invention. Further, the continuous paper may be manually performed without using the automatic paper feeder 54.

The above description of the preferred embodiments of the present invention is intended to be illustrative of the invention. Additions, omissions, substitutions, and other modifications can be made without departing from the scope of the invention. Therefore, the invention is defined by the scope of the claims, and should not be construed as being limited by the foregoing description.
