Description

  The present invention relates to a technique for improving a glass plate packing pallet for packing a glass plate laminate formed by laminating a plurality of glass plates in a flat position.

  As is well known, in recent years, various glass plates such as glass substrates for flat panel displays (hereinafter referred to as FPD) such as liquid crystal displays, plasma displays, electroluminescence displays, and field emission displays have been required to be large and thin. The fact is. Therefore, the glass plate is easily damaged, and the packaging form of the glass plate when transporting is extremely important.

  As a packaging form of this type of glass plate, one that is packaged in a state of a glass plate laminate in which a plurality of glass plates are laminated on the base portion of the pallet is known (for example, Patent Document 1). To 4). In this packing form, since the weight of the glass plate is mainly supported by the plane of the glass plate, there is an advantage that it is difficult to concentrate unnecessary stress on the side of the glass plate that is easily damaged. Therefore, it can be said that it is one of the packaging forms that can suitably prevent breakage of the glass plate corresponding to the demands for enlargement and thinning as described above.

And in the said packing form, when loading and transporting on a truck bed etc., a plurality of pallets packed with glass sheet laminates are often stacked vertically so as not to waste the upper space. . Therefore, in this case, pillars are erected at the four corners of the base part of the pallet used in the packing form, and the upper pallet is supported by the pillars.

  By the way, since the above-mentioned support | pillar needs to support an upper pallet when a some pallet is stacked, it protrudes upwards rather than a glass plate laminated body. That is, since the column is in a state of protruding upward from the glass support surface that supports the glass plate laminate in the base portion, the column and the glass plate are used when the glass plate laminate is loaded and unloaded. May interfere with the work.

  Therefore, for example, as disclosed in Patent Document 1, it is conceivable to attach the support column to the base portion in a detachable manner, but in this case, the removed support column may be lost. In particular, when various types of glass plates are packed and transported on different types of pallets, various pallets are mixed and the possibility of the loss of the columns becomes higher.

  In addition, in the above, although it demonstrated taking the case of the support | pillar which is one of the packaging parts as an example, it is arrange | positioned around the glass plate laminated body in the state protruded upwards rather than the glass plate support surface of a base part, and a glass plate laminated body The same problem may occur if the packaging parts are used for packaging. In other words, like the support column, such a packaging part obstructs the work of loading and unloading the glass plate laminate, and if it can be removed, it may be lost.

  In view of the above circumstances, the present invention loses a packaging component that is disposed around a glass plate laminate in a state of protruding upward from the glass plate support surface of the base portion and is used for packing the glass plate laminate. Therefore, it is a technical problem to store the glass plate laminate so as not to obstruct the work of loading and unloading the glass plate laminate.

  In order to solve the above problems, the present invention provides a base portion having a glass support surface for supporting the bottom surface of a glass plate laminate in which a plurality of glass plates are laminated in a flat position, and the glass of the base portion. In a pallet for packing a glass plate, which is disposed around the glass plate laminate in a protruding state protruding above the support surface and is used for packing the glass plate laminate, It is characterized in that the base portion is provided with an accommodating portion for accommodating the packaging component in a state where the height is lower than the protruding state.

  According to such a structure, a packaging component can be accommodated and stored in the accommodating part provided in the base part. That is, since the packaging parts are stored on the pallet itself, it is possible to prevent a situation where the packaging parts are lost. Moreover, since the height of the packaging component is lower than the protruding state before accommodation in the state where the packaging component is accommodated in the accommodation portion provided in the base portion, the packaging component is used for loading and unloading the glass plate laminate. It becomes difficult to get in the way, and the operation can be smoothly executed.

  Said structure WHEREIN: It is preferable that the said accommodating part is comprised so that the said packaging component may be accommodated in the downward position rather than the glass support surface of the said base part.

  If it does in this way, since the accommodated packing components do not protrude above the glass support surface of a base part, it becomes possible to perform the loading and unloading operation | work of a glass plate laminated body still more smoothly.

  Said structure WHEREIN: The said accommodating part may be provided in the internal space of the said base part.

  That is, since the base part of the pallet is usually formed with a space from the viewpoint of weight reduction, if the above configuration is adopted, the internal space can be accommodated as it is for accommodating packaging parts. There is an advantage that it can be used effectively as a part.

  Said structure WHEREIN: It is preferable that the said accommodating part is comprised by the accommodation hole provided in the said base part, and the said packing components are accommodated in the state inserted in the inside of the said accommodation hole.

  In this way, the packaging component can accommodate the packaging component in a stable state because the movable range of the packaging component is limited within the accommodation hole.

In the above configuration, it is preferable that a lid for opening and closing the inlet of the yield capacity hole.

In this way, by closing the lid after the housing by inserting the packing parts inside the yield capacity hole, it is possible to prevent a situation that the packing parts are falling off from the inlet of the receiving hole to the outside.

  Said structure WHEREIN: The said accommodating part may be comprised so that the said packaging component may be accommodated in the state which fell over the said base part.

  In this way, since the packaging component can be accommodated simply by being tilted with respect to the base portion, the packaging component accommodation operation becomes extremely easy. Note that the packaging component may be connected to a part of the base portion, and the packaging component may be tilted with the coupling portion as a fulcrum. In this case, since the packaging component is always connected to the base part, it is possible to reliably prevent the packaging component from being lost.

  Said structure WHEREIN: It is preferable that the said accommodating part is comprised so that the said packing components may be accommodated in the state adsorbed-held by magnetic force.

  In this way, since the packaging component is accommodated in a state in which the packaging component is attracted and held by the magnetic force, the accommodated packaging component does not move unnecessarily, and a stable accommodation state can be maintained. .

  In the above configuration, the packing component may be a column that is erected on the four corners of the base portion and supports the upper glass plate packing pallet when stacking a plurality of glass plate packing pallets, It may be a press plate that stands on the base portion so as to face the side surface of the glass plate laminate and prevents lateral displacement of the glass plate laminate. Further, the packing component is erected on the four corners of the base portion and faces the side surface of the glass plate laminate, and a column that supports the upper glass plate packing pallet when stacking a plurality of glass plate packing pallets. As described above, the presser plate may be configured to stand on the base portion and prevent lateral displacement of the glass plate laminate.

  As described above, according to the present invention, packing parts such as columns and press plates can be stored without losing them so as not to obstruct the work of loading and unloading the glass plate laminate.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
