Panel storage container {PANEL STORAGE CONTAINER}

This disclosure relates to a panel storage container.

In a manufacturing process that handles panels such as glass substrates for liquid crystal panels, when transporting a rectangular panel from a manufacturing device to a manufacturing device in another process or temporarily storing the panel, a panel storage container that stores a plurality of panels is used. It is used. For example, Japanese Patent Application Laid-Open No. 2019-31297 describes a panel storage container that includes a container body for storing a panel and a cover that freely covers the opening provided in the container body.

In the panel storage container described in Japanese Patent Application Laid-Open No. 2019-31297, the container body is formed by combining a plurality of parts. For example, when the top plate, side wall, bottom plate, and back wall of the container body are each composed of different members, a connecting member is used to connect these members. The container body may include a structure provided below the bottom plate and a rail member for placing the panel storage container on a conveyor or the like when it is transported. In this case, parts for mounting these members to the floor plate are additionally used. In this field of technology, there is a desire to reduce the number of parts.

This disclosure describes a panel storage container capable of reducing the number of parts.

A panel storage container according to one aspect of the present disclosure is a panel storage container for storing a plurality of panels, and includes a bottom plate and a side wall defining a receiving space for storing a plurality of panels, and a bottom plate provided on the bottom plate. It is provided with a support member for supporting, a rail member for placing the panel storage container on the transport device, and a connection member for connecting the bottom plate and the side wall and fixing the support member and the rail member.

In this panel storage container, the connecting member not only connects the bottom plate and the side wall but also secures the support member and the rail member. Therefore, there is no need to separately prepare parts for fixing the support member and parts for fixing the rail member. As a result, it becomes possible to reduce the number of parts.

In some embodiments, the connecting member may be provided with a first engaging groove for holding the bottom plate and a second engaging groove for holding the side wall. In this case, the bottom plate and the side wall are connected simply by inserting the bottom plate into the first engaging groove and inserting the side wall into the second engaging groove. Therefore, the bottom plate and the side walls can be connected without using fastening members such as bolts. As a result, it becomes possible to further reduce the number of parts.

In some embodiments, the connecting member may include a connecting portion connecting the bottom plate and the side wall, a fixing portion for fixing the support member and the rail member, and a connecting portion connecting the connecting portion and the fixing portion. The fixing portion may be mounted on the end face of the support member. The connecting portion may connect the connecting portion and the fixing portion so that the side wall is distant from the end surface of the support member. In this case, it becomes possible to expand the accommodation space compared to a configuration in which the side wall is disposed close to the cross section of the support member.

According to the present disclosure, the number of parts can be reduced.

Each block member 45 is a member for connecting three frames. Since any block member 45 connects the three frames in substantially the same way, here, the block member 45 connecting the right frame 41, the right frame 42, and the upper frame 43 is used. Explain. As shown in Fig. 4, each of the frames 41 to 43 has an L-shaped shape and is arranged so that the L-shaped corners face the outside of the container body 2. The space 40 is defined by the rear cross-section of the frame 41, the upper cross-section of the frame 42, and the right cross-section of the frame 43, and the space 40 and the receiving space ( The opening 40a communicating with 20) is defined. The block member 45 is accommodated in the space 40 and fixed to each cross section.

As shown in Fig. 7, the block member 45 includes a fixed portion 74 and a convex portion 75.

The fixing part 74 is a part fixed to the cross section of the frames 41 to 43. The fixing portion 74 includes an abutting plate 74a, an abutment plate 74b, and an abutment plate 74c.

Each of the abutting plate 74a, the abutting plate 74b, and the abutting plate 74c form a substantially right angle. The abutting plate 74b and the abutting plate 74c form substantially a right angle.

Each of the abutting plates 74a to 74c is provided with an insertion hole that penetrates the abutment plate in the thickness direction. The inner diameter of these insertion holes is larger than the outer diameter of the shaft portion of the fastening member such as a bolt. A slit 74s through which each part of the side wall 23 is fitted is provided on the surface (back surface) of the contact plate 74b opposite to the contact plate 74a. A slit 74s through which each part of the back wall 24 is fitted is provided on the surface (back surface) of the contact plate 74c opposite to the contact plate 74a. Each slit 74s is substantially perpendicular to the upper surface of the abutting plate 74a.

The convex portion 75 is a portion for pressing the frames 41 to 43 from the accommodation space 20. The convex portion 75 has a shape along the periphery of the opening 40a. The convex portion 75 includes a fitting piece 75a, a fitting piece 75b, and a fitting piece 75c. The fitting piece 75a is provided on the back surface of the abutting plate 74a and has a shape following the L-shaped concave portion of the frame 42 to which the abutting plate 74a is fixed. The fitting piece 75b is provided on the back surface of the abutting plate 74b and has a shape following the L-shaped concave portion of the frame 41 to which the abutting plate 74b is fixed. The fitting piece 75c is provided on the back surface of the abutting plate 74c and has a shape following the L-shaped concave portion of the frame 43 to which the abutting plate 74c is fixed.

The block member 45 configured in this way is accommodated in the space 40. Specifically, the abutting plate 74a overlaps the upper end surface of the frame 42, the abutting plate 74b (the back side) overlaps the rear end surface of the frame 41, and the abutting plate 74c (the back side of) overlaps the right end surface of the frame 43. At this time, the convex portion 75 is fitted into the opening 40a, each portion of the side wall 23 is inserted into the slit 74s of the abutting plate 74b, and the slit 74s of the abutting plate 74c is fitted. ), each part of the back wall 24 is inserted.

In this state, a fastening member such as a bolt is inserted into the insertion hole of the abutting plate 74a, and the fastening member is screwed into a screw hole provided in the upper end surface of the frame 42. Additionally, a fastening member such as a bolt is inserted into the insertion hole of the abutting plate 74b, and the fastening member is screwed into a screw hole provided in the rear end surface of the frame 41. Additionally, a fastening member such as a bolt is inserted into the insertion hole of the abutting plate 74c, and the fastening member is screwed into a screw hole provided on the right end surface of the frame 43.

Since the inner diameter of each insertion hole is larger than the outer diameter of the shaft portion of the fastening member, the fixing portion 74 positions each frame in the fastening direction, but does not position the frames in other directions. For example, since the frame 41 comes into contact with the abutting plate 74b in the front-back direction, it is positioned in the front-back direction. Since the frame 42 is in contact with the contact plate 74a in the vertical direction, it is positioned in the vertical direction, and the frame 43 is in contact with the contact plate 74c in the left and right directions, so it is positioned in the left and right direction. It is decided.

In the block member 45, the convex portion 75 fits into the opening 40a, so that each frame is pressed from the accommodation space 20 by the convex portion 75. For example, since the frame 41 contacts the edge of the fitting piece 75b in the up-down direction and the left-right direction, it is positioned in the up-down direction and the left-right direction. Since the frame 42 contacts the edge of the fitting piece 75a in the front-back and left-right directions, it is positioned in the front-back and left-right directions. Since the frame 43 contacts the edge of the fitting piece 75c in the up-down direction and the front-back direction, it is positioned in the up-down direction and the front-back direction.

Next, the operational effects of the panel storage container 1 will be explained with reference to FIGS. 8(a) and 8(b). FIG. 8(a) is a diagram for explaining the connection structure in the panel storage container shown in FIG. 1. Figure 8(b) is a diagram for explaining the connection structure in the panel storage container of the comparative example. As shown in (b) of FIG. 8, the panel storage container of the comparative example includes the connecting member 144 and the connecting member 145 instead of the frame 44, and the lower end of the side wall 23 is turned outward. It is mainly different from the panel storage container 1 in that it is bent.

The connecting member 144 is an L-shaped member extending in the front-back direction. The connecting member 145 is a member provided with a male thread at the bottom and a female thread (screw hole) at the top. In the panel storage container of the comparative example, the side wall portion of the connecting member 144 overlaps the right end surface of each supporting member 26a so as to contact it in the left and right directions. In this state, a fastening member such as a bolt is inserted into the insertion hole penetrating the side wall portion of the connecting member 144 in the left and right directions, and the fastening member is screwed into the screw hole provided on the right end surface of the support member 26a.

In addition, the male screw of the connecting member 145 is screwed into the screw hole provided in the rail member 27, and the rail member is configured so that the screw hole of the connecting member 145 and the insertion hole provided in the upper plate portion of the connecting member 144 overlap. A connecting member 144 is disposed on (27). The side end of the bottom plate 22 is placed on the upper surface of the upper plate portion of the connecting member 144, and the lower end of the side wall 23 is additionally overlapped with the side end of the bottom plate 22. In this state, a fastening member such as a bolt is inserted into the insertion hole at the lower end of the side wall 23, the insertion hole at the side end of the bottom plate 22, and the insertion hole at the upper plate portion of the connecting member 144, and the connecting member ( A screw is screwed into the screw hole of 145). As a result, the side end of the bottom plate 22 is clamped by the lower end of the side wall 23 and the upper plate of the connecting member 144. As a result, the bottom plate 22 and the side wall 23 are connected, and the stand portion 26 (support member 26a) and the rail member 27 are fixed.

On the other hand, as shown in Figure 8 (a), in the panel storage container 1, the frame 44 not only connects the bottom plate 22 and the side wall 23, but also connects the support member 26a and the rail member ( 27). Therefore, there is no need to separately prepare parts for fixing the support member 26a and parts for fixing the rail member 27. As a result, it becomes possible to reduce the number of parts.

The connecting portion 71 of the frame 44 is provided with an engaging groove 71a for holding the bottom plate 22 and an engaging groove 71b for holding the side wall 23. According to this configuration, the bottom plate 22 and the side wall 23 are connected simply by inserting the bottom plate 22 into the engaging groove 71a and inserting the side wall 23 into the engaging groove 71b. Therefore, the bottom plate 22 and the side wall 23 can be connected without using fastening members such as bolts. As a result, it becomes possible to further reduce the number of parts. Furthermore, since there is no need to bend the lower end of the side wall 23, the structure of the side wall 23 can be simplified.

Similarly, the upper frame 41 is provided with an engaging groove 41a for holding the top plate 21 and an engaging groove 41b for holding the side wall 23. The lower frame 41 is provided with an engaging groove 41a for holding the bottom plate 22 and an engaging groove 41b for holding the side wall 23. The frame 42 is provided with an engaging groove 42a for holding the side wall 23 and an engaging groove 42b for holding the back wall 24. The upper frame 43 is provided with an engaging groove 43a for holding the back wall 24 and an engaging groove (not shown) for holding the top plate 21. The lower frame 43 is provided with an engaging groove 43a for holding the back wall 24 and an engaging groove (not shown) for holding the bottom plate 22. These members are connected to each other simply by inserting the top plate 21, bottom plate 22, side wall 23, and back wall 24 into each engaging groove. Therefore, the top plate 21, the bottom plate 22, the side wall 23, and the back wall 24 can be connected without using fastening members such as bolts. As a result, it becomes possible to further reduce the number of parts.

In the panel storage container of the comparative example, the side end of the bottom plate 22 is sandwiched by the upper plate portion of the connecting member 144 and the lower end portion bent outwardly of the side wall 23, and the side wall portion of the connecting member 144 It is mounted on the end face of the support member 26a. Accordingly, the side wall 23 is located near the cross section of the support member 26a in the left-right direction. On the other hand, in the panel storage container 1, the connecting portion 73 is connected to the connecting portion 71 and the fixing portion so that the side wall 23 is away from the end surface of the support member 26a on which the fixing portion 72 is mounted in the left and right directions. (72) is being accessed. According to this configuration, it becomes possible to expand the storage space 20 compared to the panel storage container of the comparative example. Additionally, in the SEMI standard, the positions of the inner and outer peripheral surfaces of the flange 25 are determined. Therefore, the position of the side wall 23 can be adjusted between the inner and outer peripheral surfaces of the flange 25 in the left and right directions. Therefore, the accommodation space 20 can be expanded by bringing the side wall 23 closer to the outer peripheral surface of the flange 25.

Since the frames 41 to 44 are formed by extrusion molding, the frames 41 to 44 can be thickened. As a result, it becomes possible to improve the strength of the frames 41 to 44.

Additionally, the panel storage container according to the present disclosure is not limited to the above embodiment.

In the above embodiment, two engaging grooves are provided in each of the frames 41 to 44, but three or more engaging grooves may be provided. For example, at least one of the top plate 21, bottom plate 22, side wall 23, and rear wall 24 may be provided in duplicate.

The connecting portion 73 may connect the connecting portion 71 and the fixing portion 72 so that the connecting portion 71 is positioned immediately above the fixing portion 72 .
