Description

Technical Field

[0001] The present invention relates to a glass package. Background Art

[0002] As a form for transporting and storing a plurality of glass plates together, a glass package is known. The glass package is obtained by stacking a plurality of glass plates with protective sheets interposed therebetween to form a glass laminate, and placing the laminate on a pallet for packaging.

[0003] Patent Document 1 discloses an example of a glass package.

[0004] The package disclosed in the document includes: a glass laminated body which is placed in a horizontal position; and a tray which has a support platform (formed by a glass receiving portion 7 and a buffer body 11 in the document) that supports the laminated body from below. The package also includes a limiting member (formed by a stopper 12 and a buffer member 13 in the document) for limiting the positional deviation of the glass laminated body relative to the support platform. A plurality of limiting members are fixed to the side wall of the support platform.

[0005] When loading glass sheets on the support platform during the manufacture of the glass package or removing the glass sheets from the support platform during the unpacking of the glass package, all the restricting members need to be removed from the side walls of the support platform.

[0006] Patent Document 2 discloses an example of a mechanism for fixing a restriction member to a side wall of a support platform.

[0007] The mechanism disclosed in the document comprises: a through hole, which penetrates the side wall of the support platform (the side plate 11 of the plate-like body loading member 10 in the document); and a locking member, which is assembled with a limiting member (the movement limiting member 40 in the document) and inserted from the outer wall surface side of the side wall to the inner wall surface side through the through hole. The locking member has a head with a relatively large diameter and a shaft connected to the head and with a relatively small diameter. The through hole is formed by connecting a first opening area of ​​a shape that allows both the head and the shaft to pass through and a second opening area of ​​a shape that allows only the shaft of the two to pass through up and down. In this mechanism, after the head of the locking member passes through the first opening area, the head is hooked on the inner wall surface of the side wall while the shaft is inserted through the second opening area, so that the limiting member is fixed to the outer wall surface of the side wall.

[0011] Patent Document 2: Japanese Utility Model Registration No. 3166374 Summary of the invention

[0012] Problems to be solved by the invention

[0013] When fixing the restriction member to the side wall of the support platform, in order to improve the operability, the restriction member must be fixed quickly and reliably. Therefore, a technology that can achieve such an improvement in operability is required.

[0014] In view of the above, a technical problem to be solved is to enable a restricting member to be quickly and reliably fixed to a side wall of a support platform in a glass package in which a glass laminate is supported on a support platform in a horizontal posture and positional displacement of the laminate is restricted by a restricting member.

[0015] Solutions to Solve Problems

[0016] The first glass package for solving the above-mentioned problems comprises: a glass laminate including a plurality of glass plates arranged in a horizontal posture; a support platform supporting the glass laminate from below; a limiting member limiting positional deviation of the glass laminate relative to the support platform by contacting with the side surface of the glass laminate on the support platform; and a locking mechanism for fixing the limiting member relative to the side wall of the support platform, wherein the locking mechanism comprises: an opening portion penetrating from the outer wall surface to the inner wall surface of the side wall; and a fixing member assembled with the limiting member, wherein a dimension of the fixing member in a long side direction is shorter than an opening dimension of the opening portion along the long side direction and is longer than an opening dimension of the opening portion along the short side direction, and the fixing member is inserted from the outer wall surface side of the side wall to the inner wall surface side through the opening portion, and is engaged with the inner wall surface of the side wall while rotating around an axis extending in the thickness direction of the side wall, thereby fixing the limiting member to the outer wall surface of the side wall.

[0017] In the first glass package, the fixing member assembled with the limiting member can be easily fixed to the outer wall surface of the side wall of the support platform by (1) inserting the fixing member from the outer wall surface side to the inner wall surface side through the opening portion penetrating the side wall of the support platform, and (2) being hooked on the inner wall surface of the side wall while rotating around an axis extending in the thickness direction of the side wall. Therefore, the limiting member can be quickly fixed to the side wall of the support platform. In addition, the dimension of the fixing member in the long side direction is shorter than the opening dimension of the opening portion along the long side direction, and longer than the opening dimension of the opening portion along the short side direction. Therefore, when the above step (2) is completed, when the opening portion is observed from the main viewing direction (the direction parallel to the thickness direction of the side wall), the long side direction of the opening portion and the long side direction of the fixing member can be in a state of intersecting. That is, it is possible to reliably prevent the fixing member from falling off from the inner wall surface side to the outer wall surface side of the side wall through the opening portion. Therefore, the limiting member can be reliably fixed to the side wall of the support platform.

[0018] The second glass package is a package according to the first glass package, further comprising an auxiliary mechanism for assisting the alignment of the opening portion and the fixing member, the auxiliary mechanism comprising: a through hole extending from the outer wall surface of the side wall to the inner wall surface; and an alignment auxiliary member connected to the limiting member and inserted from the outer wall surface side of the side wall to the inner wall surface side through the through hole, the alignment auxiliary member comprising: a rod-shaped portion extending from the limiting member and inserted into the through hole; and a large diameter portion having a larger diameter than the rod-shaped portion and hooked to the inner wall surface of the side wall, the through hole comprising: a large opening area through which both the rod-shaped portion and the large diameter portion can pass; and a small opening area connected to the large opening area through which the rod-shaped portion can pass but the large diameter portion cannot pass, and the opening portion and the fixing member are aligned as the large diameter portion passes through the large opening area.

[0019] According to the second glass package, the opening and the fixing member can be aligned by passing the large diameter portion of the positioning auxiliary member through the large opening area of ​​the through hole. Thus, when the fixing member is inserted from the outer wall surface side to the inner wall surface side through the opening, the opening and the fixing member can be easily aligned. Therefore, the limiting member can be fixed to the side wall of the support more quickly.

[0020] The third glass package is a package body that is different from the second glass package body described above and includes locking mechanisms on both sides of the package body with the auxiliary mechanism sandwiched therebetween when the glass package body is viewed from above.

[0021] According to the third glass package, the restricting member is fixed to the side wall of the support stand at two locations on both sides sandwiching the auxiliary mechanism, thereby reliably eliminating the risk of the restricting member being improperly tilted relative to the horizontal plane.

[0022] The fourth glass package is a package according to any one of the first to third glass packages, wherein the locking mechanism further comprises an elastic member that can be stretched and retracted along the thickness direction of the side wall, and is linked to the positional deviation of the limiting member along the thickness direction of the side wall, and the elastic member acts as a restoring force to correct the direction of the positional deviation.

[0023] According to the fourth glass package, the elastic member acts on the restoring force that corrects the direction of the positional deviation in conjunction with the positional deviation of the restricting member, which is advantageous in restricting the positional deviation of the glass laminate relative to the support base by the restricting member.

[0024] The fifth glass package body is a package body according to the fourth glass package body, wherein the elastic member is a plurality of overlapping disc springs.

[0025] According to the fifth glass package, a plurality of overlapping disc springs are used as the elastic member, so that the length of the stroke and the magnitude of the restoring force when the elastic member is extended or contracted can be easily adjusted compared to the case of using a coil spring, for example.

[0026] The sixth glass package is a package according to any one of the first to fifth glass packages, wherein the locking mechanism further comprises a pressing mechanism for pressing and releasing the fixing member against the inner wall surface of the side wall, the pressing mechanism comprising a cam-shaped rotating portion which is arranged on the outer side surface of the limiting member and rotates while sliding with the outer side surface, the glass package being configured such that when a portion of the rotating portion which contacts the outer side surface is set as the contact portion, a distance between a rotation center line and the contact portion changes with rotation of the rotating portion, and pressing and releasing the fixing member against the inner wall surface of the side wall are performed in conjunction with the change in the distance.

[0027] According to the sixth glass package, the fixing member can be pressed against the inner wall surface of the side wall by the pressing mechanism, and since the fixing member is stably hooked on the inner wall surface of the side wall, the side wall and the limiting member can be firmly fixed. In addition, since the fixing member can be pressed and released by simply rotating the cam-shaped rotating portion, the work for firmly fixing the side wall and the limiting member can be reduced.

[0028] The seventh glass package body is the package body according to the sixth glass package body, wherein a sliding portion of the rotating portion that slides on an outer side surface of the restricting member is made of resin.

[0029] According to the seventh glass package, the sliding portion of the rotating portion that slides with the outer side surface of the restricting member is made of resin, so that the friction (friction coefficient) between the rotating portion and the outer side surface can be easily reduced.

[0030] The eighth glass package is the sixth or seventh glass package described above, wherein the pressing mechanism further includes a rod for rotating the rotating part, and the length from the rotation center line of the rotating part to the front end of the rod is 50 mm or more.

[0031] According to the eighth glass package, the length from the rotation center line of the rotating part to the tip of the rod is within the above range, so that the moment for rotating the rotating part can be sufficiently large. Therefore, the rotating part can be rotated more easily.

[0032] A ninth glass package is the eighth glass package described above, wherein the rod includes a plate-shaped main body extending from the rotating part and reinforcing parts standing relative to the main body at both ends in the short side direction of the main body.

[0033] According to the ninth glass package, since the rigidity of the rod can be sufficiently increased due to the presence of the reinforcing portion, the operability when the rod is operated to rotate the rotating portion can be improved.

[0034] Effects of the Invention

[0035] According to the glass package of the present invention, in a glass package in which a glass laminate is supported in a horizontal posture on a support table and positional deviation of the laminate is restricted by a restricting member, the restricting member can be quickly and reliably fixed to the side wall of the support table.

[0054] Hereinafter, the glass package of the embodiment will be described with reference to the drawings. Here, the X direction, Y direction, and Z direction shown in the drawings referred to in the description of the embodiment are mutually orthogonal directions. In addition, the X direction and the Y direction are horizontal directions, and the Z direction is the vertical direction.

[0055] like Figure 1 As shown, a glass package 1 (hereinafter referred to as package 1 ) includes: a glass laminate 4 (hereinafter referred to as laminate 4 ) formed by laminating a plurality of glass plates 2 with protective sheets 3 interposed therebetween; and a tray 5 on which the laminate 4 is placed in a horizontal position.

[0056] The glass plate 2 and the protective sheet 3 are both rectangular in shape. Figure 1 In the figure, for convenience of explanation, the glass plate 2 and the protective sheet 3 are shown as having the same size. However, the actual size of the protective sheet 3 is larger than the glass plate 2 in order to avoid contact between adjacent glass plates 2, 2. Thus, the end of the protective sheet 3 extends from the end of the glass plate 2.

[0057] Here, as a modification of the present embodiment, only a portion of the end of the protection sheet 3 may extend from the end of the glass plate 2. For example, three sides of the protection sheet 3 may extend from three sides of the glass plate 2, respectively, while the remaining side of the protection sheet 3 may be aligned with the remaining side of the glass plate 2.

[0058] The thickness of the glass plate 2 is, for example, 0.2 mm to 1.8 mm. The length of one side of the glass plate 2 is, for example, 1100 mm to 2500 mm. The density of the glass plate 2 is, for example, 2.0 g / cm 3 ~3.0g / cm 3 .

[0059] The thickness of the protective sheet 3 is, for example, 0.05 mm to 0.2 mm. In the present embodiment, a backing paper is used as the protective sheet 3. Of course, the present invention is not limited to this, and a foamed resin sheet or the like may be used instead of the backing paper.

[0060] The pallet 5 includes a base 6 placed on a floor of a glass manufacturing plant, a cargo bed of a conveyor, etc., and a support 7 disposed on the base 6 to support the stack 4 from below. The pallet 5 is made of metal such as stainless steel, carbon steel, or aluminum alloy, for example.

[0061] The base 6 and the support 7 are integrated, for example, by welding, etc. In the present embodiment, when the package 1 is viewed from above (viewed from the Z direction), the base 6 and the support 7 are both rectangular, and the support 7 is formed smaller than the base 6 .

[0062] Insertion ports 8 into which pillars (not shown) can be inserted and installed are provided at four corners of the base portion 6. The pillars installed in the respective insertion ports 8 have the function of supporting the upper-level package body 1 from below when the package bodies 1 are stacked in multiple stages. Holes 9 into which the claws of a forklift can be inserted are formed on the side surfaces of four locations of the base portion 6. The upper surface of the support platform 7 (the surface supporting the stacked body 4) is composed of the surface of a buffer plate formed of a foamed resin or the like.

[0063] A pressing plate (not shown) is arranged on the upper surface of the stacked body 4, and the pressing plate is fixed to the base portion 6 via a fastening tool (not shown) such as a belt, so that the stacked body 4 is held on the support 7. As the pressing plate, for example, a cushioning plate made of a foamed resin having a thickness greater than that of the protective sheet 3 and a high hardness is used. In addition, the periphery of the stacked body 4 is covered with a resin sheet (not shown) as needed to prevent dust from adhering to the glass plate 2 included in the stacked body 4.

[0064] The package body 1 further comprises: a limiting member 10 that contacts the side surface of the stacked body 4 on the support platform 7 and limits the positional deviation of the stacked body 4 relative to the support platform 7; a locking mechanism 12 that is used to fix the limiting member 10 relative to the side wall 11 of the support platform 7; and an auxiliary mechanism 13 that is used to assist the locking mechanism 12 in fixing the limiting member 10.

[0065] The restriction members 10 are fixed to the side walls 11 at four locations of the support platform 7, respectively. The number of restriction members 10 is not particularly limited, but in the present embodiment, two (eight in total) restriction members 10 are arranged for one location of the side wall 11. In addition, in the present embodiment, two locking mechanisms 12 and one auxiliary mechanism 13 are arranged for one restriction member 10. Details of the restriction member 10, the locking mechanism 12, and the auxiliary mechanism 13 will be described later.

[0066] Figure 2 The tray 5 is shown in a state where one of the two restricting members 10 arranged on the side wall 11 at one location is removed. As shown in the figure, two long holes 14 and three through holes 15 are formed at the position where the restricting member 10 is fixed in the side wall 11 (two long holes 14 and three through holes 15 exist for each restricting member 10). The three through holes 15 are arranged between the two long holes 14. The two long holes 14 and the three through holes 15 all penetrate the side wall 11.

[0067] Each long hole 14 is a component of the locking mechanism 12, which is equivalent to the opening portion of the present invention. Specifically, one of the two long holes 14 and the other are respective components of one of the two locking mechanisms 12 equipped with one limiting member 10. That is, one of the two long holes 14 and the other belong to different locking mechanisms 12. On the other hand, each through hole 15 is a component of the auxiliary mechanism 13. The three through holes 15 belong to the same auxiliary mechanism 13. It should be noted that the two long holes 14 are formed at the same height position in the up-down direction (Z direction). In addition, the three through holes 15 are also formed at the same height position in the up-down direction.

[0068] As is apparent from the arrangement of the two long holes 14 and the three through holes 15, when viewing the package body 1 from above, the auxiliary mechanism 13 is sandwiched in the middle and the locking mechanisms 12 are arranged on both sides. In this embodiment, one auxiliary mechanism 13 can simultaneously assist the two locking mechanisms 12 arranged on both sides of the auxiliary mechanism 13.

[0069] In this embodiment, when the restriction member 10 is fixed to the side wall 11 of the support platform 7, the lever 16, which is a component of the locking mechanism 12, is operated. Figure 3 Here, as described above, in this embodiment, two locking mechanisms 12 are provided for one restricting member 10. Therefore, when one restricting member 10 is fixed to the side wall 11, the lever 16 described below is operated on one and the other of the two locking mechanisms 12, respectively.

[0070] Figure 3 The left and right figures in the figure respectively show step 1 and step 2 of operating the lever 16. The lever 16 in this embodiment is rotatable around an axis 18 extending in a direction perpendicular to the outer side surface 17 of the limiting member 10 (in the thickness direction of the side wall 11) and a rotation center line 19 extending in a direction orthogonal to the axis 18.

[0071] exist Figure 3 The solid line in the left figure shows the rod 16 in a state where the restricting member 10 is not fixed relative to the side wall 11 (hereinafter referred to as the unlocked state). In this embodiment, as step 1 of operating the rod 16, Figure 3 As shown by the arrow in the left figure, the rod 16 is rotated 90° around the axis 18. As a result, the posture of the rod 16 changes from the horizontal posture (the posture shown by the solid line in the left figure) to the vertical posture (the posture shown by the double-dashed line in the left figure).

[0072] Next, in this embodiment, as step 2 of operating the rod 16, as in Figure 3 As shown by the arrow in the right figure, the rod 16 is rotated 90° around the rotation center line 19. As a result, the rod 16 changes from a state in which it stands up relative to the outer side surface 17 (a state shown by a solid line in the right figure) to a state in which it lies down along the outer side surface 17 (a state shown by a two-dot chain line in the right figure). When step 2 is completed, the restricting member 10 is fixed relative to the side wall 11 (hereinafter referred to as a locked state).

[0073] Of course, when releasing the fixing of the restricting member 10 to the side wall 11, the operation opposite to the operation of the lever 16 described above is performed. It should be noted that the structure for fixing the restricting member 10 to the side wall 11 will be described later.

[0074] Figure 4 The figure shows the periphery of the restricting member 10 and the locking mechanism 12 in the locked state. It should be noted that the two 10 and 12 in the unlocked state will be referred to later. Fig.10a As shown in Figure 4 As shown, the restricting member 10 includes a main body 20 that contacts the side surface of the stacked body 4 , and a base 21 that is connected to the lower side of the main body 20 and is fixed to the side wall 11 .

[0075] The main body 20 includes a plate 22 in a longitudinal posture and a buffer member 23 sandwiched between the inner side surface of the plate 22 and the side surface of the stacked body 4. The buffer member 23 can be elastically deformed according to the force acting on the buffer member 23. The inner side surface of the buffer member 23 is in direct contact with the side surface of the stacked body 4. The base 21 is formed of a plate in a longitudinal posture. A hole 24 is formed in the base 21 to penetrate the base 21 in the thickness direction.

[0076] Here, the plate 22 and the base 21 of the main body 20 are made of metal such as stainless steel, carbon steel, and aluminum alloy, for example. On the other hand, the cushioning member 23 is made of foamed resin such as polyolefin foam and polyethylene foam, for example.

[0077] The locking mechanism 12 has, as main components, the long hole 14 described above, which penetrates from the outer wall surface 25 of the side wall 11 to the inner wall surface 26, and the fixing member 27, which is inserted from the outer wall surface 25 side of the side wall 11 to the inner wall surface 26 side through the long hole 14 and is hooked on the inner wall surface 26. The fixing member 27 is assembled with the restricting member 10 via the components of the locking mechanism 12 described later, and the fixing member 27 is hooked on the inner wall surface 26, so that the restricting member 10 is fixed to the outer wall surface 25.

[0078] Figure 5 This is a partial cross-sectional view of the periphery of the long hole 14 as viewed from the inner wall surface 26 of the side wall 11. As shown in the figure, the long hole 14 is formed in the side wall 11 in such a manner that its long side direction is in the up-down direction and its short side direction is in the horizontal direction. However, the present invention is not limited thereto, and the long hole 14 may be formed in such a manner that its long side direction is in the horizontal direction or in a direction inclined relative to the horizontal direction.

[0079] The fixing member 27 is formed as a long strip member having a total length L shorter than the opening dimension H along the long side direction of the long hole 14 and longer than the opening dimension W along the short side direction. The shape of the fixing member 27 is not limited, but the fixing member 27 of the present embodiment is rectangular when the long hole 14 is observed from the main view direction. The fixing member 27 is composed of metals such as stainless steel, carbon steel, and aluminum alloy as an example. It should be noted that the shape of the fixing member 27 is that the dimension of the long side direction of the fixing member 27 is shorter than the opening dimension H along the long side direction of the long hole 14 (opening) and longer than the opening dimension W along the short side direction of the long hole 14 (opening), for example, it can also be an elliptical shape or an oblong shape. In addition, as for the shape of the opening, it is also possible as long as the opening dimension H along the long side direction is longer than the opening dimension W along the short side direction, for example, it can also be a rectangular shape or an elliptical shape.

[0080] The fixing member 27 can rotate around an axis 18 extending in the thickness direction of the side wall 11. The fixing member 27 can change its posture between a horizontal posture (a posture shown by a solid line) in which its long dimension direction intersects (is perpendicular to) the long side direction of the long hole 14 and a vertical posture (a posture shown by a double-dashed line) in which its long dimension direction coincides with the long side direction of the long hole 14 as it rotates around the axis 18. The fixing member 27 takes a horizontal posture in the locked state and a vertical posture in the unlocked state. That is, the fixing member 27 takes a horizontal posture as it rotates around the axis 18 and is hooked on the inner wall surface 26.

[0081] The change in the posture of the fixing member 27 is achieved by rotating the shaft member 28 engaged with the fixing member 27 around the axis 18. Figure 4 As shown, the shaft member 28 has: a shaft body 29, which is inserted into the hole 24 of the limiting member 10 in a state extending in the thickness direction of the side wall 11; and a head 30, which is provided at one end of the shaft body 29 and has a larger diameter than the shaft body 29. The shaft member 28 is made of metal such as stainless steel, carbon steel, aluminum alloy, etc. as an example. The fixing member 27 is engaged with the shaft body 29 in the shaft member 28. The fixing member 27 and the shaft body 29 are engaged in a state of "clearance fit". Therefore, the two 27, 29 are not fixed, and the two 27, 29 can move relative to each other along the direction in which the axis 18 extends (the thickness direction of the side wall 11).

[0082] like Figure 5As shown in the figure, the shaft body 29 has a cross-sectional shape that is long in one direction, and in the present embodiment, has an oblong cross-sectional shape. Thus, when the shaft body 29 rotates 90° around the axis 18, as shown by the arrow in the figure, the fixing member 27 engaged with the shaft body 29 rotates 90° around the axis 18. Accompanying this rotation, the posture of the fixing member 27 changes between a horizontal posture and a vertical posture. The shaft member 28 (shaft body 29) rotates around the axis 18 along with the operation of the rod 16 in the described step 1, and the structure will be described later. Furthermore, when the shaft member 28 rotates along with the operation of step 1, the posture of the fixing member 27 changes from a vertical posture to a horizontal posture.

[0083] Due to the above-described relationship between the dimensions of the long hole 14 and the fixing member 27 , in the package body 1 , the fixing member 27 in a vertical position can pass through the long hole 14 , while the fixing member 27 in a horizontal position cannot pass through the long hole 14 .

[0084] like Figure 4 As shown in FIG. 1 , the locking mechanism 12 includes a pressing mechanism 12a for pressing and releasing the fixing member 27 against the inner wall surface 26 of the side wall 11. The pressing mechanism 12a includes the rod 16 and the shaft member 28 described above as components, and in addition to the rod 16 and the shaft member 28, further components are provided on the outer side and the inner side of the restricting member 10. Figure 4 The state where the fixing member 27 is pressed against the inner wall surface 26 is shown in FIG. Fig.10b Shown in.

[0085] like Figure 4 As shown in FIG. 1 , among the components of the pressing mechanism 12 a , the component provided outside the restricting member 10 is a rotating portion 31 disposed on the outer side surface 17 of the restricting member 10 . The rotating portion 31 is connected to the rod 16 .

[0086] The rotating part 31 has a through shaft 32 that penetrates the shaft member 28 (shaft body 29), and the rotating part 31 is assembled with the shaft member 28 by the through shaft 32. It should be noted that in this embodiment, the fixing member 27 and the restricting member 10 are assembled via the rotating part 31 and the shaft member 28. Since the rotating part 31 is assembled with the shaft member 28, when the operation of the lever 16 in step 1 described above is performed (refer to Figure 3 ), while the rotating portion 31 rotates around the axis 18, the shaft member 28 rotates around the axis 18.

[0087] Furthermore, when the operation of the lever 16 in step 2 described above is performed (see Figure 3When the operation of step 2 is completed, the fixing member 27 is pressed against the inner wall surface 26. The structure will be described later. Regarding the operation of step 2, the rotating part 31 is in a state of always contacting the outer side surface 17 of the limiting member 10 during the rotation and before and after the rotation. Here, refer to Figure 6 The function of the rotating unit 31 when the operation of step 2 is performed will be described. Figure 6 In the figure, for convenience of explanation, illustration of some components of the locking mechanism 12 (pressing mechanism 12 a ) is omitted.

[0088] Figure 6 1 is a cross-sectional view of the periphery of the rotating portion 31 viewed from below. As shown in the figure, when the lever 16 in step 2 is operated, the lever 16 and the rotating portion 31 change from the state shown by the solid line in the figure to the state shown by the double-dashed line. At this time, as shown by arrow A, the shaft member 28 moves in the direction in which the axis 18 extends. Specifically, the head 30 of the shaft member 28 moves in a manner close to the limiting member 10. The movement of the shaft member 28 is performed due to the shape of the rotating portion 31.

[0089] The rotating portion 31 has a cam-shaped outer shape that rotates while sliding on the outer side surface 17 of the limiting member 10 when viewed from the direction along the rotation center line 19. Thus, when the portion of the rotating portion 31 that contacts the outer side surface 17 (the portion in contact) is set as the contact portion 33, the distance between the rotation center line 19 and the contact portion 33 changes as the rotating portion 31 rotates. Specifically, the distance between each other changes from D1 to D2 before and after the operation of step 2. D2 is longer than D1, and the shaft member 28 moves by the size difference ΔD (ΔD=D2-D1) between D2 and D1. In the present embodiment, the contact portion 33 before the operation of step 2 and the contact portion 33 after the operation are both straight lines when viewed from the direction along the rotation center line 19. That is, the contact portion 33 before the operation and the contact portion 33 after the operation are both formed by planes.

[0090] Regarding the rotating part 31, the sliding part 34 that slides with the outer side surface 17 of the limiting member 10 during rotation is made of resin such as POM, PTFE, etc., so as to reduce the friction coefficient. The sliding part 34 is formed into an arc shape when viewed from the direction along the rotation center line 19. The lower limit of the length LL from the rotation center line 19 to the front end of the rod 16 is more than 50mm, so that the rotating part 31 can be easily rotated around the rotation center line 19. It should be noted that the lower limit of the length LL is more preferably more than 65mm. In addition, the upper limit of the length LL can also be, for example, less than 100mm.

[0091] Here, in the present embodiment, the rod 16 is formed of a plate-shaped member extending from the rotating portion 31. However, the present invention is not limited thereto, and a plate-shaped member may be used instead of the rod 16 of the present embodiment. Figure 7 The rod 16 shown. The rod 16 comprises: a plate-shaped main body 16a extending from the rotating part 31; and a reinforcing part 16b standing up relative to the main body 16a at both ends of the short side direction (X direction) of the main body 16a. The rod 16 is formed into a U-shape in a cross section orthogonal to the axis 18 (Y direction) by the main body 16a and a pair of reinforcing parts 16b, 16b. It should be noted that one of the pair of reinforcing parts 16b, 16b can also be omitted, that is, the rod 16 can also be formed into an L-shape in a cross section orthogonal to the axis 18 (Y direction).

[0092] like Figure 4 As shown, among the components of the pressing mechanism 12 a , components disposed inside the restriction member 10 are disc springs 35 , 36 attached to the shaft body 29 of the shaft member 28 and a spring receiving member 37 fitted to the shaft body 29 .

[0093] The disc springs 35, 36 and the spring receiving member 37 are not fixed to the shaft body 29, but are relatively movable with respect to the shaft body 29 along the direction in which the axis 18 extends. The spring receiving member 37 is fitted with the shaft body 29 in a "clearance fit" state.

[0094] As described above, when the lever 16 is operated in step 2, the head 30 of the shaft member 28 moves in a manner close to the limiting member 10. At this time, the fixing member 27 is pressed toward the limiting member 10 side (the inner wall surface 26 side of the side wall 11) by the head 30 via the disc springs 35, 36 and the spring receiving member 37. As a result, the fixing member 27 is pressed against the inner wall surface 26 of the side wall 11. Of course, when the lever 16 is operated in a manner opposite to the operation in step 2, the head 30 of the shaft member 28 moves away from the limiting member 10, and the pressing of the fixing member 27 against the inner wall surface 26 is released. At this time, the disc springs 35, 36 return to their natural lengths.

[0095] The disc springs 35 and 36 are elastic members that can expand and contract along the thickness direction of the side wall 11. The outer diameters of the disc springs 35 and 36 are both smaller than the opening dimension W of the long hole 14 along the short side direction. The disc springs 35 and 36 are sandwiched between the head 30 of the shaft member 28 and the spring receiving member 37, and expand and contract according to the change in the distance between the two.

[0096] The disc springs 35 and 36 have the function of mediating the pressing of the fixing member 27 against the inner wall surface 26 as described above, and also have the function of acting on a restoring force to correct the direction of the positional deviation in conjunction with the positional deviation of the limiting member 10 along the thickness direction of the side wall 11. Here, this function will be described with reference to a specific example.

[0097] For example, when the stacked body 4 is moved by vibration during transportation of the package body 1, Figure 4 In the state shown, when the limiting member 10 is offset to the right side of the figure on the support platform 7, it follows this and is offset to the right side. At this time, the rotating part 31 arranged on the outer side surface 17 of the limiting member 10 and the shaft member 28 assembled with the rotating part 31 are also offset to the right side. Along with this, the head 30 of the shaft member 28 is also offset to the right side, and the distance between the head 30 and the spring receiving member 37 becomes shorter. In addition, the disc springs 35 and 36 shrink in accordance with the shortening of the distance between them, and the restoring force of the disc springs 35 and 36 becomes larger. The disc springs 35 and 36 use this increased restoring force to push the head 30 back to the left side. As a result, the shaft member 28 and the rotating part 31 that have temporarily offset to the right side return to the left side. The limiting member 10 follows this and returns to the left side, and the positional offset of the limiting member 10 is corrected.

[0098] In this embodiment, two disc springs 35 and 36 are attached to the shaft body 29. The two disc springs 35 and the two disc springs 36 are overlapped with each other in a state where the concave surfaces face each other (see Fig.10a , Fig.10b The disc springs 35 and 36 have different thicknesses, and the disc spring 35 is thicker than the disc spring 36. As a result, the disc springs 35 and 36 have different strokes and restoring forces when they are extended and contracted.

[0099] Here, the number of disc springs 35 and 36 can also be appropriately increased. In this case, for each of the disc springs 35 and the disc springs 36, two discs with concave surfaces facing each other or convex surfaces facing each other are taken as a group, and the total number of discs is increased in a manner of becoming an even number of discs such as four, six, eight, ..., etc. It should be noted that the configuration of the disc springs 35 and the disc springs 36 can also be exchanged (the disc springs 36 can also be configured on the side of the head 30). In addition, in the present embodiment, the disc springs 35 and 36 are used, but three or more disc springs with different thicknesses and spring constants or only one disc spring can also be used. In addition, for each of the disc springs 35 and the disc springs 36, the concave surface and the convex surface can also be overlapped in a state of facing each other. In this case, the disc springs 35 and the disc springs 36 can also be odd-numbered. Moreover, a coil spring or the like can also be used as an elastic member instead of the disc springs 35 and 36.

[0100] The spring receiving member 37 is formed in a disk shape. The outer diameter of the spring receiving member 37 is smaller than the opening dimension W along the short side direction of the long hole 14. The spring receiving member 37 is supported on one side by the fixing member 27 in a state of being hooked on the inner wall surface 26. In addition, the spring receiving member 37 receives the restoring force of the disc springs 35 and 36 by its other side.

[0101] The lock mechanism 12 further includes a disk member 38 that is fitted with the shaft body 29 of the shaft member 28 and supported by the long hole 14. The disk member 38 is fitted with the shaft body 29 in a "clearance fit" state.

[0102] The outer diameter of the disk member 38 is the same as or slightly smaller than the opening dimension W of the long hole 14 along the short side direction. The semicircular portion corresponding to the lower half of the disk member 38 is supported by the inner peripheral surface of the long hole 14 (see Figure 5 The state in which the semicircular portion is supported by the inner peripheral surface of the long hole 14 continues during the operation of the rod 16 in the steps 1 and 2 described above.

[0103] Here, the number of locking mechanisms 12 provided on one limiting member 10 is preferably two as in the present embodiment, from the viewpoint of making the limiting member 10 stably fixed relative to the side wall 11 and reducing the time required for fixing, but it can also be set to only one or more than three. In this case, the number of the long holes 14 is the same as the number of the locking mechanisms 12.

[0104] Figure 8a , Figure 8b The auxiliary mechanism 13 shown has a function of assisting the alignment of the long hole 14 and the fixing member 27 when the fixing member 27 is inserted into the long hole 14. The auxiliary mechanism 13 includes: the through hole 15 described above, which penetrates from the outer wall surface 25 of the side wall 11 to the inner wall surface 26; and the alignment auxiliary member 39 (hereinafter simply referred to as the auxiliary member 39), which is inserted from the outer wall surface 25 side of the side wall 11 to the inner wall surface 26 side through the through hole 15.

[0105] In this embodiment, as described above, three through holes 15 are formed corresponding to one restricting member 10 (in Figure 8a , Figure 8b Corresponding to the three through holes 15, three auxiliary members 39 are provided (in Figure 8a , Figure 8b The three auxiliary members 39 are all connected to the limiting member 10. The three through holes 15 and the three auxiliary members 39 have the same structure. The three auxiliary members 39 are arranged in a straight line when the limiting member 10 is viewed from the inner side (see FIG. Fig.11a as well as Fig.12a ).

[0106] Each of the three auxiliary members 39 includes a rod-shaped portion 40 extending from the restriction member 10 and inserted into the through hole 15 , and a large diameter portion 41 having a larger diameter than the rod-shaped portion 40 and engaged with the inner wall surface 26 of the side wall 11 .

[0107] The rod-shaped portion 40 is fixed to the limiting member 10. It should be noted that the fixing form of the rod-shaped portion 40 and the limiting member 10 may be any form such as riveting, bolting, bonding, etc. The cross-sectional shape of the rod-shaped portion 40 and the large-diameter portion 41 is not limited, but in this embodiment, the cross-sectional shape of the rod-shaped portion 40 and the large-diameter portion 41 perpendicular to the thickness direction of the side wall 11 is circular.

[0108] The through hole 15 has a large opening region 42 through which both the rod-shaped portion 40 and the large diameter portion 41 can pass, and a small opening region 43 connected to the large opening region 42. The small opening region 43 allows the rod-shaped portion 40 to pass, but does not allow the large diameter portion 41 to pass.

[0109] The large opening region 42 is formed into a circle having a diameter slightly larger than the large diameter portion 41 of the auxiliary member 39. On the other hand, the small opening region 43 is formed into a semi-long circle and has a width of the same size as the diameter of the rod-shaped portion 40 of the auxiliary member 39. However, this is not limited to this, and the large opening region 42 may also be formed into a polygon slightly larger than the large diameter portion 41. In addition, the width of the small opening region 43 may also be slightly larger than the diameter of the rod-shaped portion 40.

[0110] Below, refer to Figure 8a , Figure 8b as well as Figure 9a , Figure 9b A description will be given of a method of assisting the positioning of the long hole 14 and the fixing member 27 by the above-mentioned assisting mechanism 13 .

[0111] In the present package body 1, Figure 8a , Figure 8b As shown, when the large diameter portion 41 of the auxiliary member 39 passes through the large opening area 42 of the through hole 15, Figure 9a , Figure 9b As shown, the arrangement of the locking mechanism 12 and the auxiliary mechanism 13 is adjusted so that the positions of the long hole 14 and the fixing member 27 match each other.

[0112] Specifically, when the large diameter portion 41 passes through the large opening area 42, the upper end of the fixing member 27 in the longitudinal posture is located below the upper end of the long hole 14, and the lower end of the fixing member 27 is located above the lower end of the long hole 14. In addition, the entire width of the fixing member 27 converges to the opening width (opening size W) of the long hole 14 along the short side direction. In this way, the alignment of the long hole 14 and the fixing member 27 is assisted.

[0113] After the fixing member 27 is inserted into the long hole 14, Figure 8a , Figure 8b As shown, the auxiliary mechanism 13 (auxiliary member 39) is moved in the direction of arrow B until the rod-shaped portion 40 of the auxiliary member 39 contacts the lower end of the small opening area 43 in the through hole 15. As the auxiliary mechanism 13 moves, Figure 9a , Figure 9b As shown, the locking mechanism 12 moves in the direction of arrow C, and the disk member 38 moves to the lower end of the long hole 14. And the disk member 38 is supported by the inner peripheral surface of the long hole 14. Thus, it becomes a state ready for fixing the restriction member 10 relative to the side wall 11 by the locking mechanism 12. This state is the lock release state described above.

[0114] Here, as already explained, the three through holes 15 are formed at the same height position in the up-down direction. In addition, the three auxiliary members 39 are arranged in a manner that they are arranged on the same straight line when the limiting member 10 is observed from the inner side. Thus, in the unlocked state, the risk of the limiting member 10 being improperly tilted relative to the horizontal plane is eliminated. It should be noted that the number of through holes 15 and auxiliary members 39 may also be different from that in the present embodiment, but in order to prevent the limiting member 10 from tilting relative to the horizontal plane, the number of through holes 15 and auxiliary members 39 is preferably two or more.

[0115] Below, refer to Figure 10a to Figure 10c The flow of fixing the restriction member 10 to the side wall 11 using the locking mechanism 12 will be described.

[0116] Fig.10a In this state, the rod 16 takes a horizontal posture, and the fixing member 27 takes a vertical posture (see also Fig.11a , Fig.11b ). It should be noted that, in this state, the disc springs 35 and 36 do not expand or contract along the thickness direction of the side wall 11 (the direction in which the axis 18 extends) but are at a natural length. From this state, the operation of the lever 16 in the step 1 described above is performed.

[0117] When the operation of step 1 is performed, the fixing member 27 is rotated 90° around the axis 18 so that Fig.10bAs shown in the figure, the posture of the fixing member 27 becomes a horizontal posture. With this, the long dimension direction of the fixing member 27 and the long side direction of the long hole 14 are crossed (orthogonal), and the fixing member 27 is hooked on the inner wall surface 26 of the side wall 11. In this state, the rod 16 takes a vertical posture. It should be noted that the disc springs 35 and 36 are still at their natural length. From this same state, the operation of the rod 16 in step 2 described above is performed.

[0118] When the operation of step 2 is performed, the head 30 of the shaft member 28 moves in a manner close to the restricting member 10 ( Fig.10b L1 ratio Fig.10c L2 length), thus becoming Fig.10c At this time, the head 30 presses the fixing member 27 via the disc springs 35, 36 and the spring receiving member 37, so that the fixing member 27 is pressed against the inner wall surface 26 of the side wall 11. In the locked state, the disc springs 35, 36 are shortened to a length smaller than the natural length. It should be noted that the rod 16 is in a state of lying down along the outer side surface 17 of the limiting member 10 (see also Fig.12a , Figure 12b ).

[0119] Through the above process, the restricting member 10 is fixed to the outer wall surface 25 of the side wall 11 .
