A laminating apparatus (not shown) that disassembles and takes out a predetermined storage container 20 is disposed. This laminating apparatus can employ a known configuration.

<Storage container 20>
As shown in FIGS. 2 and 3, the storage container 20 is formed in a substantially rectangular shape in plan view with an upper surface open, and a placement portion 21 on which the liquid crystal glasses 2 are placed one by one, and the placement portion 21. Four side walls 22 formed on the outside, guide frames 23 and 23 which are formed at opposing positions and serve as mounting portions on the conveyors 30 and 30, and formed at opposing positions and chucked by a laminating apparatus (not shown). The frame is composed of side frames 24, 24, a support frame 25 below the mounting portion 21 and connecting the side walls 22. The pair of guide frames 23 and 23 are formed on the outer surfaces of the pair of side walls 22 and 22 facing each other, and the side frames 24 and 24 are also formed on the outer surfaces of the pair of side walls 22 and 22 facing each other.

  The mounting portion 21 is stretched between the opposing sides of the side wall 22 (in this embodiment, the sides on which the side frames 24 and 24 are formed) such that the plurality of linear members 26 are substantially parallel to each other. As a result, a substantially smooth surface is formed. The liquid crystal glass 2 is placed in a horizontal state on the upper surface of the placement portion 21 formed by the linear member 26. As the linear member 26, a member having a circular cross section is used, and for example, a wire or the like is used. Further, the linear members 26 may be provided at substantially equal intervals, or partially spaced or widened, but at least overlap with the transfer roller 60 of the transfer device 6 in plan view. The part is formed with an insertion port 21a spaced so that the transfer roller 60 can pass vertically.

  The side wall 22 is formed so as to surround the outer periphery of the mounting portion 21, and is formed so that the upper end is located above the horizontal plane of the mounting portion 21 in this embodiment. In this manner, the side wall 22 also serves as a fall-off prevention wall that prevents the liquid crystal glass 2 placed on the placement unit 21 from being displaced in the horizontal direction and falling off the storage container 20. .. Are provided at the upper end of the side wall 22, and fitting holes (not shown) are formed at positions corresponding to the protrusions 28, 28. The storage container 20 is formed so that it can be laminated | stacked up and down by making this protrusion 28 * 28 ... fit in a fitting hole. Since the projections 28, 28,... Are fitted in the fitting holes, the storage containers 20 can be prevented from being displaced in the horizontal direction.

  The opposite sides of the side wall 22 are formed such that the upper end of the side wall 22 is lowered at this portion, and a transfer port 27 through which the liquid crystal glass 2 can pass in a horizontal state is opened. In this embodiment, the transfer port 27 is opened in the side wall 22 on the side where the guide frames 23 and 23 are formed. Therefore, in the storage container 20 that is transported along the transport path 3, the liquid crystal glass 2 is carried in and out from the direction orthogonal to the transport path 3. However, the opening position of the transfer port 27 is not limited to this. Further, the transfer port 27 is formed so that the liquid crystal glass 2 can pass through in a state where the storage container 20 is laminated, and the height of the transfer port 27 in the vertical direction, that is, the side wall 22 and the side wall 22 stacked on the upper stage. Is ensured at least so as not to prevent the liquid crystal glass 2 from being carried in and out.

  The guide frames 23, 23 are flange-like members that protrude from the outer peripheral surface of the side wall 22, and protrude in a substantially horizontal direction from the outer peripheral surface of the side wall 22 so that the protruding portion is flat. By making the guide frames 23 and 23 smooth, as described above, the liquid crystal glass 2 can be easily passed through the transfer port 27, and the liquid crystal glass 2 can be prevented from being damaged, and the storage container. 20 can be stably conveyed along the conveyor 30. The guide frames 23 and 23 are brought into contact with the left and right conveyors 30 and 30 from above when the storage container 20 is placed on the transport path 3. However, the guide frames 23 and 23 may be formed integrally with the side wall 22.

  The side frames 24 and 24 protrude in a substantially U shape in a side view so as to open from the outer peripheral surface of the side wall 22 toward the side, and when stacking or stacking the stacked body 100, It is chucked by the chuck device. The side frames 24, 24 may be formed only at positions corresponding to the vicinity of the corner of the storage container 20, or formed integrally with the side wall 22, and further, a portion corresponding to the vicinity of the corner of the storage container 20. A recess may be formed in the recess and the recess may be chucked. The side frame 24 and the guide frame 23 may be formed so as to be shared. Thus, by providing the side frames 24 and 24, the storage container 20 can be easily laminated or separated.

  The support frame 25 has rod-shaped members intersecting substantially parallel and substantially at right angles, and between the opposing sides of the side wall 22 (in this embodiment, the side on which the guide frames 23 and 23 are formed and the side frame 24). (Between the side on which 24 is formed). Thus, by providing the support frame 25, the rigidity can be increased when the storage container 20 is formed by the side wall 22 and the linear member 26. In particular, even when a plurality of storage containers 20 are stacked, when the storage container 20 positioned at the lowest position is prevented from being deformed, and the lower surface of the storage container 20 is supported and moved up and down. In addition, the side wall 22 and the like can be prevented from being distorted and deformed. However, the support frame 25 is not necessarily provided.

As shown in FIGS. 4 and 5, the transfer device 6 is disposed at each of the stations 31 and 32, and the liquid crystal glass 2 is carried into and out of the laminated body 100 by the transfer device 6. The transfer device 6 includes a transfer roller 60 as a lifting mechanism as a means for changing the relative position of the transfer roller 60 and the stacked body 100, and the transfer roller 60 that contacts and drives the lower surface of the liquid crystal glass 2. The support part 61 which supports and fixes 60, and the lifter 62 etc. which raise / lower the laminated body 100 to an up-down direction are comprised.

  The stations 31 and 32 are provided with a pair of left and right conveyors 33 similar to the conveyor 30 instead of the conveyor 30 on the travel path 3. The conveyor 33 uses a roller conveyor and is configured to be retracted so as not to obstruct the passage path of the stacked body 100 that is rotated downward by a lifter 62 and is rotated downward by a cylinder (not shown). In a state where the conveyor 33 is retracted, the guide frame 23 is not in contact with the conveyor 33, and the stacked body 100 can move in the vertical direction at the stations 31 and 32. The retracting mechanism of the conveyor 33 is not limited to this, and may be retracted by moving in the width direction of the transport path 3 (a direction perpendicular to the transport direction), for example.

  The entire transfer roller 60 constitutes a roller conveyor that conveys the liquid crystal glass 2 in a direction along the communication path 5. Each transfer roller 60 is arranged at an interval and supported and fixed by a support portion 61 so that the relative position cannot be changed. The transfer roller 60 is positioned below the transport path 3, and its upper end is fixed at a position lower than the lower end of the stacked body 100 transported along the transport path 3, and the upper end of the conveyor 50 in the conveyor communication path 5. The liquid crystal glass 2 is configured to be smoothly transferred between the transfer roller 60 and the conveyor 50. The conveyance surface by the transfer roller 60 and the conveyance surface by the conveyor 50 are arranged below the conveyance surface (mounting surface) of the laminate 100 by the conveyor 30.

  Each transfer roller 60 is disposed so as to overlap the liquid crystal glass 2 in a plan view so as to be able to drive and convey the liquid crystal glass 2 in a predetermined direction, and to be in uniform contact with the lower surface of the liquid crystal glass 2. However, the position and number of the transfer rollers 60 are not particularly limited as long as the liquid crystal glass 2 is supported by the transfer rollers 60 and can be transported. Further, in relation to the arrangement of the transfer rollers 60, the transfer rollers 60 can pass in the vertical direction in the mounting portion 21 of the storage container 20 at positions overlapping with the transfer rollers 60 in plan view. Through holes 21a, 21a... Are formed. In the present embodiment, as described above, the placement portion 21 is formed by the linear member 26, and each linear member 26 is disposed at a position that does not overlap with each transfer roller 60 in plan view.

  The lifter 62 is configured such that a support member 62a abuts on the lower surface of the laminated body 100 and is movable up and down while supporting the laminated body 100. In the present embodiment, the support member 62 a is configured to contact the lower end of the side wall 22 of the lowermost storage container 20 and the lower end of the support frame 25 to support the stacked body 100. As described above, when the laminated body 100 is moved up and down by the lifter 62, the relative position between the laminated body 100 and the transfer roller 60 is changed in the vertical direction.

  The carrying out of the liquid crystal glass 2 at the station 31 will be described with reference to FIGS. 4 and 6. When the laminated body 100 on which the liquid crystal glass 2 is placed reaches the station 31, the lifter 62 of the transfer device 6. Is raised, the support member 62a comes into contact with the lower surface of the lowermost storage container 20, and the laminated body 100 is supported, and the left and right conveyors 33 and 33 are rotated downward to be retracted (FIG. 6 ( a)). Next, the lifter 62 is lowered, and the transfer roller 60 is brought into contact with the lower surface of the liquid crystal glass 2 through the insertion openings 21a, 21a,. Then, the transfer roller 60 is driven in a state where the liquid crystal glass 2 is lifted slightly higher than the placement portion 21 (the linear member 26) and does not come into contact with the bottom surface (the placement portion 21) of the storage container 20 immediately above. The liquid crystal glass 2 is unloaded from the storage container 20 through the transfer port 27 and transferred to the conveyor 50 in the communication path 5 (see FIG. 6B).

  When the liquid crystal glass 2 is unloaded from the lowermost storage container 20, the lifter 62 is lowered again, and the transfer roller 60 passes through the insertion port 21a of the storage container 20 stacked one step upward. The liquid crystal glass 2 is brought into contact with the lower surface of the liquid crystal glass 2 and is driven and conveyed from the storage container 20. As described above, the transfer device 6 arranged in the station 31 is configured so that the liquid crystal glass 2 can be continuously conveyed in order from the inner and lower storage containers 20 of the stacked storage containers 20.

  On the other hand, the introduction of the liquid crystal glass 2 at the station 32 will be described. When the empty laminated body 100 is stacked and reaches the station 32, the lifter 62 of the transfer device 6 also disposed at the station 31 is The support member 62a comes into contact with the lower surface of the lowermost storage container 20 to support the laminated body 100, and the left and right conveyors 33 and 33 are pivoted downward and retracted. Next, the lifter 62 is lowered, and the transfer roller 60 is stopped with the transfer roller 60 slightly protruding from the mounting portion 21 of the uppermost storage container 20 through the insertion port 21a of the storage container 20. The When the transfer roller 60 is driven, the liquid crystal glass 2 conveyed on the conveyor 50 is transferred into the uppermost storage container 20 through the transfer port 27.

  When the liquid crystal glass 2 is carried into the uppermost storage container 20, the lifter 62 is raised again and stops at a position where the upper end of the transfer roller 60 slightly protrudes from the placement portion 21 of the lower storage container 20. Then, the subsequent liquid crystal glass 2 is carried into the storage container 20 from the conveyor 50 of the communication path 5. in this way. The transfer device 6 disposed at the station 32 is configured such that the liquid crystal glass 2 can be successively carried in from the upper storage container 20 among the stacked storage containers 20.

  As described above, the liquid crystal glass 2 is placed one by one, and the storage container 20 formed so as to be capable of being stacked is stacked in the vertical direction (a state in which the stacked body 100 is configured). By changing the relative position with respect to the mounting roller 60 so that the liquid crystal glass 2 is carried into and out of the storage container 20, for example, the liquid crystal glass 2 is extracted by a transfer device equipped with a robot arm or the like. The liquid crystal glass 2 can be carried in and out with a simple configuration without using a simple configuration. That is, as compared with the case of transferring with a robot arm, each storage container 20 does not require a space for inserting a fork between the bottom surface and the liquid crystal glass 2, and the number of transfer rollers 60 allows liquid crystal to be transferred. By supporting almost the entire surface of the glass 2 uniformly, the deflection of the liquid crystal glass 2 can be reduced as compared with the fork supporting the central portion, and the space for extracting the liquid crystal glass 2 from the storage container 20 can be suppressed. Can save space.

  Moreover, since the storage container 20 can be laminated | stacked and can convey a lot of liquid crystal glass 2 at once, conveyance efficiency can be improved. Further, the present invention can be applied to a system configuration using an existing cassette-type storage container, and the liquid crystal glass 2 can be transported one by one by separating the storage container 20 (single-sheet transport), which is suitable for each processing step. Can be used, and the handling of the storage container 20 and the productivity of the product can be improved. Furthermore, since it becomes easy to stack the storage containers 20 to be stacked in a predetermined order or to change the stacking order and reload, the sampling and sorting can be performed easily.

  In particular, in the present embodiment, the placement portion 21 of the storage container 20 is formed by a plurality of linear members 26 having a circular cross section disposed so as to uniformly support the entire surface so as to suppress the deflection of the liquid crystal glass 2. Therefore, the area in contact with the liquid crystal glass 2 is very small, the liquid crystal glass 2 is prevented from being damaged during transportation, and the mounting portion 21 can be easily manufactured as compared with the case where a large number of support members are provided. Moreover, it can suppress that the liquid crystal glass 2 bends by supporting with the some linear member 26. FIG. Furthermore, the linear member 26 can be made thin to reduce the bulk height of the mounting portion 21, the height direction of the storage container 20 can be shortened, and the space of the apparatus can be reduced. The number of liquid crystal glasses 2 stored in the laminated body 100 that has been laminated can be increased to improve the conveyance efficiency. Moreover, since the liquid crystal glass 2 can be supported uniformly, it can respond easily to the enlargement of the liquid crystal glass 2. However, the mounting part 21 is not limited to the case where it is formed from the linear member 26, and the liquid crystal glass 2 can be mounted on the upper surface of the plate-like member, and the insertion port 21a is opened at a predetermined location. May be.

  Moreover, like the raising / lowering mechanism of the transfer device 6 shown in the present embodiment, the transfer roller 60 is fixed in position and the stack 100 is moved up and down, so that the stack 100 is only moved. The liquid crystal glass 2 can be carried in and out continuously, and the upper end of the transfer roller 60 and the upper end of the conveyor 50 in the communication path 5 are always kept at a constant height, so that the liquid crystal glass 2 can be carried in and out stably. Can be done. Such a configuration is suitable for a system configuration for mass production of small varieties. In addition, as a raising / lowering mechanism, the relative position of the laminated body 100 and the transfer roller 60 is fluctuate | varied by moving the transfer roller 60 up and down with respect to the laminated body 100 stopped by the station 31, and the laminated body 100 is changed. You may comprise so that the liquid crystal glass 2 may be carried in / out.
