BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to packing of a plate-shaped object, and in particular, a plate-shaped package body provided with a holding pad on a base for arranging a plurality of plate-shaped objects made of glass in parallel in an upright posture, and a method for packing the same. About.
[0002]
[Prior art]
In recent years, flat displays such as a plasma display (PDP) and a liquid crystal display (LCD) have been put into practical use as image display devices become larger and lighter and thinner. Large glass plates used in 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 in a storage holder (hereinafter referred to as a container). After that, they are taken out one by one from the container and transferred to an assembly line or the like.
[0003]
This glass plate is usually housed in a container at equal intervals in parallel in an upright position, and while maintaining a high degree of cleanliness, breakage such as cracking does not occur The interior of the container has a special structure because it needs to be stored and held.
[0004]
As a specific example, for example, in Patent Document 1, a bottomed box body made of a foamed resin molded body is fixedly installed on the upper surface of a base (in the same publication, a bottom base), and a plurality of sheets are placed inside the box body. A container in which an L-shaped pad composed of a side plate portion and a bottom plate portion formed with holding grooves for holding a glass plate is incorporated, and the upper opening of the box is covered with a lid (in the same publication, a transport box) ) Is disclosed. FIG. 17 is a schematic diagram illustrating the details.
[0005]
In the system shown in FIG. 17, the glass plate 4 is stored in a box 3 including a storage container 1 having opposing holding grooves 1 a and 1 a on the inner wall surface and a lid 2 fitted to 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.

[Problems to be solved by the invention]
However, when a plurality of glass plates stored and held in a container are taken out after the container of this type is transported to an assembly factory or the like, for example, automatic take-out by a take-out device in order from the glass plate at one end thereof is performed. Done. There are many types of take-out devices in which the trajectory of the robot hand that holds the glass plate is set to be constant, and in order to cope with this, during the period from the previous stage of automatic take-out to the end of the work, The need arises to keep the container on hold at the correct location on the work station.
[0008]
Therefore, in order to meet such a requirement, a reference part is provided on a base that is a member having higher rigidity than other members among the constituent members of the container, and this reference part is used as a reference part provided in the work station. The container is positioned in contact with a block or the like. That is, the container is positioned with respect to the take-out device provided in the work station 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.
[0009]
However, as described above, even if the container base is accurately positioned with respect to the work station and thus the take-out device, if the relative position of the glass plate stored in the container to the take-out device is not accurate, The glass plate cannot be removed smoothly by the robot hand. In particular, if the position of the glass plate that is first taken out by the take-out device, that is, the position of the glass plate that exists at one end in the arrangement direction has been distorted, a series of take-out operations by the take-out device will generally hinder. However, the work becomes difficult.
[0010]
Therefore, although 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, conventionally, after the pad is assembled and fixed inside the case, Since it was customary to manufacture the container by fixing this case to the upper part of the base, no consideration has been given to the positional relationship between the pad and the base.
[0011]
As a specific example, the above publication does not suggest any positioning of the pad with respect to the base, and there are no specific components for performing such positioning. Moreover, as in the container disclosed in the same publication, 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, the rigidity of both is extremely low. In addition, since high-precision processing is difficult, sufficient positioning accuracy cannot be ensured.
[0012]
For this reason, even if the base and the box are accurately positioned, it cannot be avoided that the positional relationship between the base and the pad is out of order. As a result, when the glass plate held on the pad is taken out by the take-out device, a situation in which the position of the glass plate and the trajectory of the robot hand do not correspond accurately causes smooth removal of the glass plate automatically. It 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 a direction parallel to the glass plate, but positioning with the robot hand is particularly important. Since it is the thickness direction of a glass plate, the position change in this case does not contribute to smoothing of the automatic taking-out operation | work of a glass plate.
[0014]
In this publication, it is described that the position change of the pad is a configuration for storing and holding glass plates of different sizes. However, since the position of one of the pads can only be changed, the range of the size of the glass plate that can be accommodated is narrow, and if the glass plate becomes smaller, the center of the glass plate moves away from the center of the container, which is unbalanced. There's a problem.
[0015]
Moreover, the container disclosed in the same publication can only change the position of the pad with respect to the longitudinal direction of the box having a rectangular plan view, and cannot change the orientation of the pad. The glass plate having a size corresponding to the scale direction and the glass plate having a size corresponding to the short direction cannot be appropriately dealt with without waste.
[0016]
The above-described problems are not limited to the above-described flat display glass plates, and similarly occur in other glass plate-like bodies that are stored and held in parallel in an upright posture.
[0017]
The conventional method of FIG. 17 is ideal for maintaining the cleanliness, but since the dimension L1 and the height L2 between the holding grooves 1a and 1a of the storage container 1 are fixed, glass of one kind of size is used. There is a drawback that only the plate 4 can be stored and cannot be shared by other sizes of plate-like objects. Further, when the glass plate 4 is stored and taken out, friction is generated between the end portion 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 of it. However, since the volume is very large, the environmental load on the disposal process is large, and it is costly to dispose without adversely affecting the environment. There is a problem that it takes. Further, when the box 3 is reused, it needs to be returned, but there is also a problem that the transportation cost increases due to the large volume.
[0018]
In view of the above-described problems, the present invention improves the cleanliness by suppressing the generation of dust during storage and removal, and can be used for plate-like objects of different sizes, and also improves workability during removal. An object of the present invention is to provide a plate-shaped packaging body and a packaging method that can achieve excellent environmental measures by reducing the amount of packaging material used and also reduce transportation costs.
[0019]
[Means for Solving the Problems]
  In order to achieve the above-described object, the package of plate-like objects according to the present invention has a plurality of holding grooves for holding a plurality of substantially rectangular plate-like objects in parallel at a predetermined interval in the plate thickness direction. In a package of plate-like objects that are arranged in a substantially upright manner by a holding pad and stored and held on a base, the holding pad is a lower L-shaped section having a substantially L-shaped cross section composed of a substantially vertical portion and a substantially horizontal portion. 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 a lower pad comprising a substantially horizontal portion that is positioned on the front end side of the substantially horizontal portion of the lower L-shaped holding pad and supports the lower end of the plate-like object, and the lower pad is configured to hold the lower L-shaped holding pad. It is assembled to the upper surface of the base so that the distance to the pad can be adjusted,An upper holding pad having a plurality of holding grooves for holding the plate-like object in parallel at a predetermined interval in the plate thickness direction on the upper part of the plate-like object held in parallel with the lower L-shaped holding pad on the base. And a packaging material that encloses the entire plate-like object held by the two holding pads together with the two holding pads, and restrains the upper holding pad from the base to the entire plate-like object. It is characterized by preventing separation.
[0020]
  In the present invention, on the base, the upper and lower ends and both end portions 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, so that each plate-like object is predetermined in the plate thickness direction. While being held at intervals, it is positioned in the width direction and the vertical direction. By encapsulating this with a packaging material, the plate-like object is blocked from the outside world, and contamination of the plate-like object is prevented.In this case, the distance between the lower pad, which is located at the front end side of the substantially horizontal portion of the lower L-shaped holding pad and supports the lower end of the plate-like object, with respect to the lower L-shaped holding pad can be adjusted. If the plate-like body is relatively large by being assembled to the upper surface portion of the base, the lower pad is moved away from the lower L-type holding pad to widen the interval, and the plate-like body In the case of a relatively small size, by moving the lower pads closer to each other and narrowing the interval, it is possible to appropriately store and arrange even plate-like bodies of different sizes.
[0021]
In the present invention, 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. The held L-shaped holding pad extends from the lower L-type holding pad to the upper surface of the base. This means that there are no other holding pads, stoppers, or the like that are obstructed when pulling out substantially in parallel. Actually, if the plate-like object is drawn out in parallel, friction is generated between the end of the plate-like object and the holding groove, and dust is generated due to wear of both members. However, it can be used as long as there is no obstacle when the plate-like object is conveyed in the horizontal direction in a state of being detached from the holding groove.
[0022]
The holding pad used for the package of the plate-like material in the present invention is a molded body made of a low-rigidity cushioning material, for example, a foamed molded body, more specifically, polypropylene, polyethylene, polystyrene, or a copolymer thereof. It is preferable that it is comprised with the foaming molding which becomes. The base is preferably composed of a member having higher rigidity than the holding pad, for example, a pallet formed of hard resin or the like. Polyethylene bags, polypropylene, and the like are suitable as packaging materials for encapsulating the entire plate-like material together with both holding pads.
[0023]
Further, in the package of plate-like objects of the present invention, the lower L-shaped holding pad has an upper surface portion of the base so that a holding groove at one end thereof is in a predetermined position with respect to the 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 that holds a plurality of plate-like bodies is assembled to the upper surface portion of the highly rigid base, the assembling rigidity and assembling accuracy are increased. And 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, when the reference block or the like of the work station where the take-out device is installed and the reference portion of the base are aligned, the lower L-shaped holding pad is positioned with high accuracy with respect to the take-out device. As a result, even if the robot hand has a constant trajectory, the plate-like bodies arranged on the lower L-shaped holding pad can be taken out one by one in order, and a series of automatic removal of the plate-like bodies is possible. Work can be performed smoothly.
[0025]
Moreover, it is preferable that the lower L-shaped holding pad is detachably assembled to the upper surface of the base with a bolt or the like, and the lower L-shaped holding pad is maintained while maintaining high assembling rigidity and accuracy as described above. It is possible to easily remove and attach, and thus change the orientation of the holding pad in plan view without causing deterioration in workability.
[0026]
In this case, it is preferable that the lower L-shaped holding pad is positioned with respect to the holding groove arrangement direction between the lower L-type holding pad and the reference portion of the base. That is, the robot hand cannot accurately take out the plate-like body unless it enters the ideal position in the thickness direction of the plate-like body. The position in the holding groove arrangement direction is important. Accordingly, if the lower L-shaped holding pad is positioned in the holding groove arrangement direction with the reference portion of the base, the plate-like body can be smoothly taken out by the robot hand.
[0027]
Furthermore, according to such a configuration, in the process in which the robot hand sequentially takes out the plate-like bodies, if the position of the plate-like bodies to be first taken out (especially the position in the arrangement direction) is accurate, The plate-like bodies held in the holding grooves can be accurately grasped one by one in order and the take-out operation can be executed, and a series of automatic take-out operations for all the plate-like bodies can be smoothly performed. . In this case, even if there is some error in the arrangement pitch of the subsequent plate-like bodies, the automatic removal operation of those plate-like bodies will be smooth as long as the position of the plate-like bodies to be taken out first is accurate. It can be done.
[0028]
On the other hand, if the position of the plate-like body to be taken out first is out of order, the robot hand interferes with the plate-like body or is too far away from the plate-like body, making it impossible to perform the take-out operation. There is a fear. Therefore, if the holding groove existing at one end in the holding groove arrangement direction or the vicinity thereof is positioned with respect to the reference portion of the base, not only the plate-like body to be taken out first but also the subsequent plate-like body. It is possible to perform a smooth removal operation.
[0031]
Moreover, it is preferable that the package body of the plate-shaped object of this invention is provided with the guide member which guides the adjustment operation | movement of the distance of the said lower L-type holding pad and the said lower pad on the upper surface part of the said base.
[0032]
If comprised in this way, since a space | interval can be adjusted by moving a lower pad to an arbitrary position efficiently along a guide member, it avoids that the position of a lower pad becomes imbalanced with respect to the center of a plate-shaped object. In addition, not only existing types of plate-like bodies but also new-type plate-like bodies can be appropriately arranged and stored. Furthermore, by positioning the lower L-shaped holding pad and the lower pad with respect to the reference position of the base, it is possible to avoid the center of gravity of the plate-like body stored and held from being unbalanced with respect to the center of the base. In particular, it is possible to prevent a situation in which the holder tilts and adversely affects the plate-like body inside the package body during transportation.
[0033]
Moreover, it is preferable that the packaging body of the plate-shaped object of this invention restrains the separation | separation of the whole plate-shaped object from a base by restraining the said upper holding pad to the said base with packaging material.
[0034]

[0100]
【The invention's effect】
  In the package of plate-like objects according to the present invention, the holding pad is a lower L-type holding pad having a substantially L-shaped cross section composed of a substantially vertical portion and a substantially horizontal portion, and the lower L-type holding pad is the plate-like shape. The object is arranged on the base so that the object can be taken out in a substantially horizontal direction, and the plate-like object is placed on the upper part of the plate-like object held in parallel with the lower L-type holding pad on the base. An upper holding pad having a plurality of holding grooves for holding in parallel at a predetermined interval, and a packaging material for enclosing the entire plate-like object held by the both holding pads together with the holding pads, The upper holding pad is constrained to the base to prevent separation of the entire plate-like object from the base, so that a plurality of upper and lower and both side end portions of the plate-like object are provided on the inner wall surfaces of the upper and lower holding pads. By fitting in 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 encapsulating this with a packaging material, the plate-like object is blocked from the outside world, and contamination of the plate-like object is prevented.In addition, a lower pad for supporting the lower end of the plate-like body is provided, and the lower pad is assembled to the upper surface of the base so that the distance to the lower L-type holding pad can be adjusted. Even if it is a body, the arrangement | sequence accommodation can be performed appropriately.
[0101]
The packaging is stabilized by restraining both the support members in the vertical direction by a fixing band to prevent their separation.
[0102]
Moreover, according to the package of the plate-shaped object of the present invention, the holding pad including the side plate portion and the bottom plate portion is assembled at a predetermined position on the upper surface portion of the base with respect to the reference portion of the base. Therefore, the holding pad is positioned in a state in which its assembling rigidity and assembling accuracy are maintained high, so that the positioning accuracy can be ensured, and the holding pad can be removed and attached, and the orientation of the holding pad in plan view can be assured. The change can be easily performed without deteriorating workability. And, for example, when the robot hand sequentially takes out the plate-like body 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 In addition, the positional relationship between the plate-like body to be taken out first and the robot hand becomes accurate, and a series of plate-like body taking-out operations from the beginning to the end of taking-out can be performed smoothly.
[0104]
Furthermore, by providing a guide member for guiding the adjustment operation of the distance between the lower L-shaped holding pad and the lower pad on the upper surface of the base, not only the existing plate-shaped body but also a new variety It is possible to appropriately arrange and store the plate-like bodies and to avoid the position of the lower pad being unbalanced with respect to the center of the plate-like body.

It becomes possible.
[0106]
Further, the packaging material is a stretch film strip, the entire plate-like object held by both holding pads is encapsulated together with both holding pads, and the upper holding pad is constrained to the base to form a plate-like object. Since the entire separation is prevented, the upper cover and the stretch film band restrain the entire plate-like object on the base, and no dust or dust adheres to the plate-like body due to the intrusion of outside air. A cleanliness can be maintained, and separation of the whole plate-shaped object from the base can be prevented.
[0107]
In addition, since the upper holding pad is constrained to the base together with the packaging material, and the fixing band is provided to prevent the separation of the entire plate-shaped object encapsulated from the base by the packaging material, the packaging is highly stabilized. Can withstand harsh transport conditions.
[0108]
In the plate-shaped package of the present invention, the plurality of lower L-shaped holding pads are arranged on the base so that the plate-shaped objects can be taken out in a substantially horizontal direction. When a plurality of lower L-shaped holding pads are arranged on the base so that the back surfaces of the substantially vertical portions without holding grooves are opposed to each other, the predetermined size is further increased. It becomes possible to improve the storage efficiency of the plate-shaped object on the base.
[0109]
The plate-shaped package of the present invention is an upper L-type holding pad whose upper holding pad has a substantially L-shaped cross section consisting of a substantially vertical portion and a substantially horizontal portion, and is a plate held in parallel on a base Since it is disposed at the diagonal position of the lower L-shaped holding pad of the object, the volume can be minimized. Further, when the same size as the lower L-shaped holding pad is used, the number of member types is reduced, the packaging material can be easily managed, and it can be manufactured at low cost.
[0110]
In addition, the plate-like package of the present invention is entirely covered with a box-like body, so that a dedicated container or the like is not necessary, and a truck, a shipping, or the like is required for each package. Distance transportation is possible.
[0111]
In addition, since the box-shaped body of the present invention can be divided into at least an upper lid portion and a sleeve portion surrounding the outer periphery, the box-shaped body can be easily folded into a plane and stored at the time of purchase. The handling volume at the time of return, return and disposal is minimized, and the transportation cost can be suppressed.
[0112]
In addition, the plate-shaped package of the present invention has the reinforcing material disposed on the box-shaped body, so that it is possible to place other loads on the plate-shaped package, A plurality of plate-shaped package bodies can be stored and transported at a high density by placing other plate-shaped package bodies on the arranged plate-shaped package bodies.
[0113]
