TECHNICAL FIELD OF THE INVENTION
The present invention relates to packing of plate-like objects, and in particular, a plate-like object package having a holding pad for arranging a plurality of glass plate-like objects in parallel in an upright posture on a base, and a method of packing the same. About.
[0002]
[Prior art]
2. Description of the Related Art In recent years, as image display devices have become larger, lighter and thinner, flat displays such as plasma displays (PDP) and liquid crystal displays (LCD) have been put to practical use. Large glass plates used for this type of display are transported from a glass plate manufacturing plant or the like to a display assembly plant or the like in a state where a plurality of glass plates are arranged and held as a set in a storage holder (hereinafter, referred to as a container). Then, they are taken out one by one from the container and transferred to an assembly line or the like.
[0003]
In general, a plurality of the glass plates are housed in the container at an equal interval in parallel in an upright posture, and furthermore, while maintaining a high degree of cleanliness, so as not to cause breakage such as cracks. Due to the necessity of storing and holding, the inside of the container has a special structure.
[0004]
As a specific example, for example, in Patent Document 1, a bottomed box made of a foamed resin molded article is fixedly installed on the upper surface of a base (the bottom in this publication), and a plurality of sheets are placed inside the box. A container in which an L-shaped pad including a side plate portion and a bottom plate portion in which a holding groove for holding the glass plate is formed is incorporated, and an upper opening portion of the box body is covered with a lid (in the publication, a transport box). ) Is disclosed. The details are described below with reference to a schematic diagram shown in FIG.
[0005]
In the system shown in FIG. 17, a glass plate 4 is stored in a box 3 including a storage container 1 having opposed holding grooves 1a and 1a on the inner wall surface and a lid 2 fitted into the storage container 1. In this method, since the storage container 1 and the lid 2 are fitted, the cleanliness of the internal glass plate 4 can be maintained.
[0006]

JP 2001-31165 A (page 3-4, FIG. 1-2)
[0007]
[Problems to be solved by the invention]
However, when transporting this type of container to an assembly plant or the like, when removing a plurality of glass plates stored and held in the container, for example, automatic removal by a removal device in order from the glass plate at one end thereof is performed. Done. Since there are many types of the unloading device in which the trajectory of the robot hand holding the glass plate is set to be constant, in order to cope with this, from the stage before the automatic unloading to the end of the work. The need arises to keep the containers in place at the correct position at the work station.
[0008]
Therefore, in order to respond to such a request, a reference portion is provided on a base which is a member having higher rigidity than other members among the constituent members of the container, and this reference portion is used as a reference portion serving as a reference portion provided in the work station. 2. Description of the Related Art A container is positioned by being brought into contact with a block or the like. That is, by aligning the reference portion of the base serving as the reference on the container side with the reference block serving as the reference on the work station side, the container is positioned with respect to the unloading device provided in the work station.
[0009]
However, as described above, even if the base of the container is accurately positioned with respect to the work station and, therefore, the unloading device, if the relative position of the glass sheet housed inside the container with respect to the unloading device is not accurate, The work of removing the glass plate by the robot hand cannot be performed smoothly. In particular, if the position of the glass plate first taken out by the take-out device, that is, the position of the glass plate at one end in the arrangement direction is misaligned, a series of take-out operations by the take-out device will hinder the whole. And the task becomes difficult.
[0010]
Therefore, the accuracy of the positional relationship between the pad having the holding groove for holding each glass plate and the base having the reference portion is extremely important, but conventionally, after the pad is assembled and fixed inside the case, However, since it is customary to manufacture a container by fixing the case to the upper portion of the base, no consideration has been given to the positional relationship between the pad and the base.
[0011]
To give a specific example, the above publication does not suggest anything about positioning the pad with respect to the base, and there is no specific component for performing such positioning. Moreover, according to the configuration in which the pad made of the cushioning material (foamed molded body) is assembled inside the bottomed box made of the foamed molded body as in the container disclosed in the same publication, the rigidity of both is extremely low. In addition, since high-precision machining is difficult, sufficient positioning accuracy cannot be ensured.
[0012]
For this reason, even if the base and the box are accurately positioned, it is impossible to prevent the positional relationship between the base and the pad from being out of order. As a result, when the glass plate held on the pad is taken out by the take-out device, the position of the glass plate and the trajectory of the robot hand do not accurately correspond to each other, and the glass plate is automatically taken out. Is a big hindrance.
[0013]
In addition, according to the container disclosed in the publication, as described above, the position of the pad can be changed in the direction parallel to the glass plate, but positioning between the pad and the robot hand is particularly important. Is in the thickness direction of the glass plate, so that the position change in this case does not contribute to smoothing the automatic removal operation of the glass plate.
[0014]
This publication describes that the position change of the pad is a configuration for storing and holding glass plates of different sizes. However, since one pad can only change the position, the size range of the glass plate that can be supported is narrow, and when the glass plate becomes small, the center of the glass plate moves away from the center of the container, resulting in imbalance. There's a problem.
[0015]
In addition, the container disclosed in the publication can only change the position of the pad in the longitudinal direction of the box having a rectangular shape in plan view and cannot change the direction of the pad. It is not possible to properly cope with a glass plate having a size corresponding to the shading direction and a glass plate having a size corresponding to the short shading direction without waste.
[0016]
The above-described problem is not limited to the glass plate of the above-described flat type display, but also occurs in a similar manner with respect to another glass plate-shaped body in which a plurality of glass plates are stored and held in parallel in an upright posture.
[0017]
Further, the conventional method of FIG. 17 is ideal for maintaining cleanliness, but since the dimension L1 and the height L2 between the holding grooves 1a and 1a of the storage container 1 are fixed, one type of glass is used. There is a drawback that only the plate 4 can be stored and cannot be used for other sizes of plate-like objects. Further, when the glass plate 4 is stored and taken out, friction occurs between the end of the glass plate 4 and the holding groove 1a, so that generation of dust due to wear of both members has been a problem. In addition, when the box 3 becomes unusable, it is necessary to dispose it. However, since the volume is very large, the environmental burden of the disposal is large, and the cost for disposing it without adversely affecting the environment is expensive. There is such a problem. Further, when the box 3 is to be reused, it must be returned, but there is also a problem that the transportation cost increases due to its large volume.
[0018]
In view of the above problems, the present invention suppresses generation of dust at the time of storage and removal, improves cleanliness, can be used for plate-like objects of different sizes, and improves workability at the time of removal. It is an object of the present invention to provide a plate-like package and a method for packing the same, which are excellent and can also achieve environmental measures and a reduction in transportation cost by reducing the amount of packaging material used.
[0019]
[Means for Solving the Problems]
In order to achieve the above object, the package of a plate-like object according to the present invention has a plurality of holding grooves for holding a plurality of substantially rectangular plate-like objects in parallel at predetermined intervals in the thickness direction thereof. In a package of plate-like objects which are arranged and arranged substantially upright in parallel by holding pads and stored and held on a base, the holding pads have a substantially L-shaped lower L-shaped cross section comprising a substantially vertical portion and a substantially horizontal portion. A holding pad, wherein the lower L-shaped holding pad is disposed on the base so that the plate-like object can be taken out in a substantially horizontal direction, and is held in parallel with the lower L-shaped holding pad on the base. An upper holding pad having a plurality of holding grooves for holding the plate-shaped objects in parallel at predetermined intervals in the plate thickness direction is disposed on the upper part of the plate-shaped object, and the entire plate-shaped object held by the two holding pads is arranged. And a packaging material for encapsulating the upper holding pad together with the two holding pads. Constrained to Kimoto stand to prevent separating of the entire plate-like material from the base and is characterized by comprising.
[0020]
According to the present invention, the upper and lower ends of the plate-like object are fitted into a plurality of holding grooves provided on the inner wall surfaces of the upper and lower holding pads on the base, so that each of the plate-like objects has a predetermined thickness in the plate thickness direction. It is held at intervals and positioned in its width and up and down directions. By enclosing this with a packaging material, the plate-like material is shielded from the outside world, and contamination of the plate-like material is prevented.
[0021]
In the present invention, the phrase that the lower L-shaped holding pad is disposed on the base so that the plate-like object can be taken out in a substantially horizontal direction means that the held plate-like object is moved from the lower L-shaped holding pad to the upper surface of the base. This means that other holding pads, stoppers, and the like, which become obstacles when pulling out substantially in parallel, are not provided. Actually, if the plate is pulled out exactly in parallel, friction occurs between the end of the plate and the holding groove, and dust is generated due to wear of both members. However, any material can be used as long as there is no obstacle in transporting the plate-like object in the horizontal direction in a state where it is removed from the holding groove.
[0022]
As the holding pad used for the package of the plate-like material in the present invention, a molded article made of a low-rigid cushioning material or the like, for example, a foam molded article, more specifically, polypropylene, polyethylene, polystyrene, or a copolymer thereof, or the like It is preferable to be constituted by a foamed molded article. Further, it is preferable that the base is formed of a member having higher rigidity than the holding pad, for example, a pallet formed of a hard resin or the like. A polyethylene bag, polypropylene, or the like is suitable as a packaging material for enclosing the entire plate with the holding pads.
[0023]
Further, in the plate-shaped package according to the present invention, the lower L-shaped holding pad may be arranged such that a holding groove at one end thereof is located at a predetermined position with respect to a reference portion of the base. It is characterized by being assembled in.
[0024]
According to such a configuration, since the lower L-shaped holding pad for holding the plurality of plate-like bodies is mounted on the upper surface of the highly rigid base, the mounting rigidity and the mounting accuracy are increased. Then, while maintaining such characteristics, the lower L-shaped holding pad is positioned at a predetermined position on the upper surface of the base with respect to the reference portion of the base, so that the positioning accuracy is sufficient. Become. Therefore, if the reference block or the like of the work station in which the removal device is provided is aligned with the reference portion of the base, the lower L-shaped holding pad is positioned with high precision with respect to the removal device. As a result, even if the robot hand has a fixed trajectory, the plate-like bodies arranged on the lower L-shaped holding pad can be taken out one by one accurately one by one, and a series of automatic take-out of the plate-like bodies is achieved. Work can be performed smoothly.
[0025]
In addition, the lower L-shaped holding pad is preferably detachably mounted on the upper surface of the base with bolts or the like. As described above, while maintaining high mounting rigidity and mounting accuracy, the lower L-shaped holding pad is It is possible to easily perform detachment and attachment, and thus change in the direction of the holding pad in plan view, without deteriorating workability.
[0026]
In this case, it is preferable that the lower L-shaped holding pad is positioned between the reference portion of the base and the holding groove arrangement direction. That is, unless the robot hand enters the ideal position in the thickness direction with respect to the plate-shaped body, the plate-shaped body cannot be taken out accurately. The position in the holding groove arrangement direction is important. Therefore, if the lower L-shaped holding pad is positioned in the holding groove arrangement direction between the lower L-shaped holding pad and the reference portion of the base, the work of removing the plate-like body by the robot hand can be performed smoothly.
[0027]
Furthermore, according to such a configuration, in the process of sequentially taking out the plate-like bodies by the robot hand, if the position of the plate-like body to be taken out first (particularly the position in the arrangement direction) is accurate, the robot hand will The plate-shaped members held in the holding grooves can be sequentially and accurately grasped one by one to perform the picking-out operation, and a series of automatic picking-up operations for all the plate-shaped members can be smoothly performed. . In this case, even if there is some error in the arrangement pitch of the subsequent plate-like bodies, as long as the position of the plate-like body to be removed first is accurate, the automatic removal operation of those plate-like bodies can be smoothly performed. It can be done.
[0028]
On the other hand, if the position of the plate to be removed first is out of order, the robot hand may interfere with the plate or be too far away from the plate to perform the removal operation. There is a fear. Therefore, if the holding groove existing at one end in the holding groove arrangement direction or its vicinity is positioned with respect to the reference portion of the base, not only the plate to be taken out first but also the subsequent plate. It is also possible to execute a smooth take-out operation.
[0029]
Further, the package of the plate-like material of the present invention is provided with a lower pad for supporting a lower end of the plate-like body, and the lower pad is provided on an upper surface of the base so that a distance to the lower L-shaped holding pad can be adjusted. Preferably, it is assembled.
[0030]
According to this structure, when the plate is relatively large, the lower pad is moved away from the lower L-shaped holding pad so as to widen the gap, and the plate is relatively small. In this case, the lower pads are moved closer to each other to narrow the gap, so that even if the plate-like bodies are of different sizes, they can be properly arranged and stored.
[0031]
Further, it is preferable that the plate-shaped package of the present invention includes a guide member for guiding an operation of adjusting a distance between the lower L-shaped holding pad and the lower pad on the upper surface of the base.

【The invention's effect】
In the package of a plate-shaped material according to the present invention, the holding pad is a lower L-shaped holding pad having a substantially L-shaped cross section including a substantially vertical portion and a substantially horizontal portion, and the lower L-shaped holding pad is formed of the plate-shaped material. An object is disposed on the base so as to be able to be taken out in a substantially horizontal direction, and the plate-like object is placed in the thickness direction on the plate-like object held in parallel with the lower L-shaped holding pad on the base. An upper holding pad having a plurality of holding grooves for holding in parallel at predetermined intervals is arranged, and a packaging material for enclosing the entire plate-like object held by the both holding pads together with the both holding pads, Since the upper holding pad is restrained by the base to prevent the entire plate-like object from separating from the base, the upper and lower and both side ends of the plate-like object are provided on the inner wall surfaces of the upper and lower holding pads. By fitting into the holding groove, each plate-like object is held at a predetermined interval in the plate thickness direction. Both are positioned in the width direction and the vertical direction. By enclosing this with a packaging material, the plate-like material is shielded from the outside world, and contamination of the plate-like material is prevented.
[0101]
Packing is stabilized by constraining both support members in the vertical direction with a fixing band to prevent their separation.
[0102]
According to the plate-shaped package of the present invention, the holding pad including the side plate and the bottom plate is assembled at a predetermined position on the upper surface of the base with respect to the reference portion of the base. Therefore, the holding pad is positioned in a state where its mounting rigidity and mounting accuracy are maintained at a high level, so that the positioning accuracy can be ensured, and the holding pad can be removed and attached, and thus, the orientation of the holding pad in plan view. Changes can be easily made without deteriorating workability. Then, by assembling the holding pad on the upper surface of the base so that the holding groove at one end thereof is at a predetermined position with respect to the reference portion of the base, for example, when the robot hand sequentially takes out the plate-like body In addition, the positional relationship between the plate-shaped body to be taken out first and the robot hand becomes accurate, and a series of plate-shaped body taking-out operations from the start to the end of the take-out can be performed smoothly.

It is possible to increase the efficiency of storing a plate-like object on the base.
[0109]
The plate-like package of the present invention is an upper L-shaped holding pad in which the upper holding pad has a substantially L-shaped cross section including a substantially vertical portion and a substantially horizontal portion, and the plate held in parallel on the base. Since it is arranged at a diagonal position of the lower L-shaped holding pad of the object, its volume can be minimized. Further, if the same size as the lower L-shaped holding pad is used, the number of kinds of members is reduced, the management of the packing material is facilitated, and the manufacturing can be performed at a low cost.
[0110]
Further, in the plate-like package of the present invention, since the entire plate-like object is covered with the box-like body, a dedicated container or the like is not required, and a remote unit such as a truck or a shipping unit is required for each package. Distance transportation becomes possible.
[0111]
In the package of the plate-like material of the present invention, the box-like body can be divided into at least an upper lid and a sleeve surrounding the outer periphery, so that these can be easily folded into a flat surface and stored at the time of purchase. The handling volume at the time of return, return and disposal is minimized, and transportation costs can be suppressed.
[0112]
Further, since the plate-like package of the present invention has the reinforcing member disposed on the box-like member, it is possible to place other luggage on the plate-like member, and the reinforcing member is used. By placing another plate-shaped package on the arranged plate-shaped package, a plurality of plate-shaped packages can be stored and transported at a high density.
