They are stacked in a state of being sandwiched and packed in a packing box. Interleaf serves as a cushioning material or spacer to prevent the laminated panels from coming into direct contact with each other and being damaged or stuck together. Resin sheets or paper sheets can be used as interleaving paper. Used as

  Conventionally, when a panel is packed in a packing box, the panel is sucked and held from above using a suction pad and transferred to the packing box, and the slip sheet is sucked and held from above using a suction pad. Then, this is performed by alternately repeating the step of transferring it into the packaging box (see, for example, JP-A-2008-63093 (Patent Document 1)). On the other hand, when unpacking the panel from the packing box, the slip sheet is sucked and held from above using the suction pad and transferred to the outside of the packing box, and the panel is sucked from above using the suction pad.

It is a schematic diagram. Next, with reference to these FIG. 4 thru | or FIG. 7, the operation | movement of the panel packing apparatus which operate | moves along the procedure of the panel packing method in this Embodiment and the procedure of the said panel packing method is explained in full detail.

  As shown in FIG. 4, in the panel packing method in the present embodiment, first, the liquid crystal panel 10 is carried in (step S101). Specifically, the liquid crystal panel 10 is carried onto the stage 121 using the liquid crystal panel carry-in device described above.

  Next, as shown in FIG. 4, the slip sheet 20 is supplied onto the liquid crystal panel 10 placed on the stage 121 (step S102). Specifically, as shown in FIG. 5, the elevator 111 is lifted in the vertical direction using the elevator drive unit 102, and the most vertical direction among the plurality of interleaf sheets 20 placed on the elevator 111. The interleaf paper 20 located on the upper side is brought into contact with the first supply roller 112, and the first supply roller 112 and the second supply rollers 113 </ b> A and 113 </ b> B are rotationally driven using the supply roller driving unit 103.

Guided by the rollers 113A and 113B, supplied onto the stage 121 and set on the liquid crystal panel 10 placed on the stage 121.

  Next, as shown in FIG. 4, the liquid crystal panel 10 is sucked using the suction pad 123 while the slip sheet 20 is placed on the liquid crystal panel 10 (step S <b> 103). Specifically, as shown in FIG. 6, the head 122 is lowered in the vertical direction using the head driving unit 104 toward the liquid crystal panel 10 placed on the stage 121. At this time, the plurality of suction pads 123 provided on the head 122 reach the exposed surface 11 of the liquid crystal panel 10 through the through holes 21 of the interleaf paper 20 provided corresponding to the suction pads 123. When the suction surface of the suction pad 123 comes into contact with the exposed surface 11 of the liquid crystal panel 10, the driving of the head 122 is stopped, and the negative pressure pump 105 is driven to generate a negative pressure on the suction surface of the suction pad 123. Thereby, the liquid crystal panel 10 is sucked and held by the plurality of suction pads 123 while the interleaf sheet 20 is placed.

  Next, as shown in FIG. 4, the liquid crystal panel 10 is transferred together with the interleaf paper 20 from the stage 121 into the packaging box 30 with the interleaf paper 20 placed on the liquid crystal panel 10 (step S <b> 104). . Specifically, as shown in FIG. 7, while the liquid crystal panel 10 is sucked and held using the suction pad 123, the head 122 is raised in the vertical direction using the head drive unit 104, and then the head 122 is placed on the mounting table. The liquid crystal panel 10 is moved together with the interleaf paper 20 in the packing box 30 by moving the head 122 in the horizontal direction toward the mounting box 30 placed on 128 and then lowering the head 122 toward the mounting table 128 in the vertical direction. (See the arrows in the figure). The driving of the head 122 is stopped when the lower surface of the liquid crystal panel 10 comes into contact with the bottom surface of the packaging box 30 or the upper surface of the slip sheet 20 already placed in the packaging box 30.

  Next, as shown in FIG. 4, the suction of the liquid crystal panel 10 by the suction pad 123 is released (step S105). Specifically, by stopping the driving of the negative pressure pump 105, the negative pressure generated on the suction surface of the suction pad 123 is extinguished and the suction of the liquid crystal panel 10 by the suction pad 123 is released, and then the head 122 is moved. Using the head driving unit 104, the head is raised in the vertical direction and further moved in the horizontal direction to return the head 122 to the initial position.

  By repeatedly performing the above steps S101 to S105, the plurality of liquid crystal panels 10 can be packed in the packing box 30 with the interleaf paper 20 sandwiched therebetween.

  The interleaf paper 20 is placed on the liquid crystal panel 10 by packing the liquid crystal panel 10 in the packing box 30 using the panel packing method and panel packing apparatus 100 and the panel packing paper 20 in the present embodiment described above. It becomes possible to transfer the liquid crystal panel 10 together with the interleaf paper 20 into the packing box 30 in the state where it has been made. This eliminates the need for the suction holding of the slip sheet, which was necessary in the past, and causes problems such as taking two slip sheets due to static electricity, winding up the slip sheet due to airflow, and dropping the slip sheet from the suction pad. Thus, the liquid crystal panel can be efficiently packed in the packing box. Moreover, the occurrence of the above-described problems can be prevented even when a large liquid crystal panel is packed in a packing box or when a very thin slip sheet is used. Therefore, the work efficiency of the packing work is dramatically improved, which contributes to a reduction in manufacturing cost.

  In addition, by using the panel packing apparatus 100 according to the present embodiment described above, an interleaving sheet adsorbing and holding mechanism, which has been conventionally required, becomes unnecessary. Therefore, the apparatus is not complicated or enlarged, and a small panel packing apparatus having a simple configuration can be obtained.

  FIG. 8 and FIG. 9 are schematic diagrams for explaining the configuration and operation of a panel packing device according to a modification of the present embodiment. Next, with reference to these FIG. 8 and FIG. 9, the structure and operation | movement of the panel packing apparatus which concern on the modification of this Embodiment are demonstrated.

It has a pressing part 123a. Each of the pressing portions 123a is provided so as to protrude from the lower surface of the head 122 such that the tip thereof faces downward in the vertical direction, and the tip is located on the same plane. The pressing portion 123 a corresponds to pressing means for pressing the slip sheet 20 placed on the liquid crystal panel 10 toward the panel surface of the liquid crystal panel 10 in a state where the liquid crystal panel 10 is sucked and held using the suction pad 123. .

  As shown in FIG. 8, when the liquid crystal panel 10 is packed using the panel packing device according to the modification of the present embodiment, the suction pad 123 remains in a state where the interleaf sheet 20 is placed on the liquid crystal panel 10. When the liquid crystal panel 10 is sucked by using (when step S103 in FIG. 4 described above), the tips of the plurality of pressing portions 123a provided on the head 122 abut on the predetermined portion 22 of the interleaf paper 20. Thus, the interleaf paper 20 is pressed toward the panel surface of the liquid crystal panel 10.

  In such a configuration, when the liquid crystal panel 10 is transferred as shown in FIG. 9 (at the time of step S104 in FIG. 4 described above), the interleaf paper 20 is always pressed against the liquid crystal panel 10. Therefore, the slip sheet 20 can be prevented from floating above the liquid crystal panel 10 due to the influence of the airflow. Accordingly, the above-described transfer of the liquid crystal panel 10 can be performed at a higher speed, the tact time required for the transfer of the liquid crystal panel 10 can be shortened, and the packaging operation can be performed more efficiently. At the same time, it becomes possible to prevent problems such as the slip sheet 20 floating and being caught on the suction pad 123.

At this time, the plurality of suction pads 213 provided on the head 212 are made to reach the exposed surface of the liquid crystal panel 10 through the through holes 21 of the interleaf paper 20 provided corresponding to the suction pads 213. Then, when the suction surface of the suction pad 213 comes into contact with the exposed surface of the liquid crystal panel 10, the driving of the head 212 is stopped, and the negative pressure pump 203 is driven to generate a negative pressure on the suction surface of the suction pad 213. Thus, the liquid crystal panel 10 is sucked and held by the plurality of suction pads 213 while the interleaf sheet 20 is placed.

  Next, as shown in FIG. 12, the liquid crystal panel 10 is transferred together with the interleaf paper 20 from the packing box 30 onto the stage 218 while the interleaf paper 20 is placed on the liquid crystal panel 10 (step S202). . Specifically, as shown in FIG. 13, the head 212 is raised in the vertical direction using the head driving unit 202 while the liquid crystal panel 10 is sucked and held using the suction pad 213, and then the head 212 is moved to the stage 218. Then, the head 212 is moved downward in the vertical direction toward the stage 218, and the liquid crystal panel 10 is moved together with the interleaf paper 20 onto the stage 218 (see the arrow in the figure). When the lower surface of the liquid crystal panel 10 comes into contact with the upper surface of the stage 218, the driving of the head 212 is stopped.

  Next, as shown in FIG. 12, the suction of the liquid crystal panel 10 by the suction pad 213 is released (step S203). Specifically, by stopping the driving of the negative pressure pump 203, the negative pressure generated on the suction surface of the suction pad 213 is eliminated, and the suction of the liquid crystal panel 10 by the suction pad 213 is released, and then the head 212 is moved. The head drive unit 202 is used to raise the head 212 in the vertical direction and further move in the horizontal direction to return the head 212 to the initial position.

  Next, as shown in FIG. 12, the slip sheet 20 on the liquid crystal panel 10 is removed (step S204). Specifically, as shown in FIG. 14, the collection roller 222 is moved onto the slip sheet 20 placed on the liquid crystal panel 10 by using the collection roller movement drive unit 205 to be brought into contact with the slip sheet 20 and collected. The roller 222 is rotationally driven using the collection roller driving unit 204. As a result, the slip sheet 20 placed on the liquid crystal panel 10 is removed from the liquid crystal panel 10 and moved into the recovery box 224, and is recovered by the recovery box 224. Subsequently, the collection roller 222 is returned to the initial position by using the collection roller movement drive unit 205.

  Next, as shown in FIG. 12, the liquid crystal panel 10 is carried out (step S205). Specifically, the liquid crystal panel 10 is unloaded from the stage 218 using the above-described liquid crystal panel carry-out device.

  By repeatedly performing the above steps S201 to S205, the liquid crystal panel 10 can be unpacked from the packing box 30 in which the plurality of liquid crystal panels 10 are packed with the interleaf paper 20 sandwiched therebetween.

  By unpacking the liquid crystal panel 10 from the packing box 30 using the panel unpacking method and the panel unpacking apparatus 200 and the panel packing slip 20 in the present embodiment described above, the slip sheet 20 is placed on the liquid crystal panel 10. It becomes possible to transfer the liquid crystal panel 10 together with the interleaf paper 20 from the packing box 30 while being placed on the packaging box 30. This eliminates the need for the suction holding of the slip sheet, which was necessary in the past, and causes problems such as taking two slip sheets due to static electricity, winding up the slip sheet due to airflow, and dropping the slip sheet from the suction pad. Thus, the liquid crystal panel can be efficiently unpacked from the packaging box. Moreover, the occurrence of the above-described problems can be prevented even when a large liquid crystal panel is unpacked from a packaging box or when a very thin slip sheet is used. Therefore, the work efficiency of the unpacking work is dramatically improved, which contributes to a reduction in manufacturing cost.

  In addition, the panel unpacking apparatus 200 according to the present embodiment described above eliminates the need for a conventional slip-sheet suction holding mechanism. Therefore, the apparatus does not become complicated or large, and a simple panel unpacking apparatus can be obtained with a simple configuration.

  In addition, panel unpacking apparatus 200 according to the present embodiment may be provided with a pressing portion as provided in panel packaging apparatus 100 according to the modified example of the first embodiment described above. In that case, the said press part is provided in the head 212 of the transfer part 210 of the panel unpacking apparatus 200. FIG. With this configuration, the liquid crystal panel 10 can be transferred at a higher speed, and the tact time required for the transfer of the liquid crystal panel 10 can be shortened and unpacked more efficiently. In addition to being able to work, it is possible to prevent problems such as the slip sheet 20 being lifted and caught on the suction pad 213.

  In Embodiments 1 and 2 of the present invention described above and modifications thereof, a roller is used as a slip sheet supply unit that supplies slip sheets without suction and a slip sheet removal means that strips slip sheets without suction. An explanation was given by exemplifying. However, the slip sheet supply means and the slip sheet removing means are not limited to those using this roller, and other non-feeding means such as a transport means using a robot arm or a transport means using airflow spraying, etc. Any type of adsorption type can be used.
