JP5476248B2 - Corner member and panel lamination method using the same - Google Patents

Description

  The present invention relates to a corner member used when stacking and storing or transporting panel-like products such as solar cell panels and liquid crystal panels. In particular, the present invention relates to a corner member that can be stacked so that there is no back and forth rattling during stacking operations using a robot or the like and can be easily released.

  As a means for stacking panel-shaped products such as solar cell panels at a predetermined interval, a corner member that is applied to a corner of the panel-shaped product and stacked in itself is used. The corner member has a column portion extending in the stacking direction of the panel-shaped product and a receiving portion that receives a corner of the panel-shaped product. When stacking panel-shaped products, corner members are applied to the four corners of the panel-shaped product, and the corner members themselves are stacked.

  There exists a corner member currently disclosed by patent document 1 as such a corner member. This corner member is shown in FIG. The corner member 100 includes a column part 110 and a receiving part 120. It has been proposed that one or a plurality of “tenon” 111 is formed on the upper surface of the column part 110 and a cavity 113 into which each of the “tenon” 111 fits is formed on the lower surface ( For example, see Patent Document 1). By fitting the tenon 111 and the space 113, the corner member 100 is stacked so as not to rattle up and down. Note that the proposal also describes that a groove can be formed with “Sane” instead of “Eleven” and a void.

JP 2006-32978

  When laminating panel-like products using this corner member, if there is a clearance in the planar direction of the panel-like product between the upper and lower corner members (direction perpendicular to the laminating direction), the panel will be displaced from front to back, left and right, Cannot be stacked straight. In such a case, the corner members cannot be automatically stacked by the robot. Therefore, the clearance in the plane direction of the panel-like product between the upper and lower corner members is preferably zero.

  When the upper and lower corner members are positioned by fitting the tenon 111 and the cavity 113 as in the above example, the clearance between the outer surface of the tenon 111 and the cavity 113 can be reduced to zero. It is necessary to closely contact the inner peripheral surface. Then, when the stacking height is increased and a large load is applied to the corner member 100, the frictional force between the contact surfaces becomes excessive, and both surfaces may bite and become difficult to separate. In such a case, it becomes difficult to pick up the products one by one when releasing the stacking. Furthermore, if the clearance is small, the “tenon” 111 may not fit into the interior of the space 113 due to deformation such as warpage or contraction when forming the corner member. Then, the corner members 100 cannot be stacked straight, and the product may be inclined.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a corner member that can make the clearance in a direction orthogonal to the stacking direction zero and easily cancel stacking. . Another object of the present invention is to provide a corner member suitable for unmanned work using a robot or the like.

  The corner member of the present invention is applied to a corner of the panel-like product when the panel-like product is stacked, transported, stored, packed, and / or transported in a state where a plurality of the panel-like products are stacked, and a plurality of the corner members are stacked. A receiving portion for receiving a corner of the panel-shaped product, and a weight of the panel-shaped product laminate that is connected to the receiving portion and extends in a stacking direction of the panel-shaped product (referred to as a Z direction). And a misalignment preventing means for preventing misalignment of a plurality of stacked corner members in two lateral directions (X direction and Y direction) perpendicular to the Z direction. Is a contact surface between the corner members to be stacked, and is a contact surface (referred to as an X plus contact surface) that serves to prevent the X-direction displacement in the positive direction, and a displacement stop in the X-direction in the negative direction. Contact (Referred to as “X minus contact surface”), contact surface (referred to as “Y plus contact surface”) that serves as a positive displacement stop in the Y direction, and contact surface that serves as a negative displacement stop in the Y direction (Y The X plus abutment surface and the X minus abutment surface are surfaces inclined in the opening direction opposite to the Z direction, and the Y plus abutment surface. The contact surface and the Y minus contact surface are inclined with respect to the opening direction opposite to the Z direction, and the X plus direction contact surface and the X minus direction contact surface are separated from each other. The Y plus direction abutment surface and the Y minus direction abutment surface are formed at positions spaced apart from each other, and there is almost no deviation between the X direction and the Y direction during stacking. It is characterized by .

The panel-like product is typically a plate-like product having a square shape in plan shape, and includes a solar cell panel, a liquid crystal panel, a panel made of glass, plastic, metal, wood, a combination thereof, or the like.
The opening direction refers to a direction in which the clearance between the contact surfaces opens when the two corner members are moved in the direction in which stacking (stacking) is released (the direction in which they are separated). The length of the contact surface on the horizontal plane (XY plane) is preferably about 3 mm in consideration of the tolerance of the automatic stacking robot. In other words, the inclination angle of the contact surface with respect to the vertical plane (XZ plane, YZ plane) is preferably larger than 135 °.

  The positions separated from each other are positions as far as possible in the XY plane of the corner member, and the plus X contact surface and the minus X contact surface, or the plus Y contact surface and the minus Y contact surface, Is a positional relationship that does not overlap in the X direction or the Y direction, or a positional relationship that is not constrained by facing each other.

  In the case of the prior art, positioning is performed by sandwiching both side surfaces of “tenon” and “sane” with “vacant spaces” or “grooves”. In this case, the plus X abutment surface and the minus X abutment surface correspond to both side surfaces of the tenon and the ridge, the abutment surfaces face each other, and the distance between the two becomes short. Then, if the clearance at the time of stacking is zero in order to realize zero deviation, both side surfaces of “tenon” and “sane” and “vacant spaces” or “grooves” are bitten and become difficult to separate.

  On the other hand, the positive contact surface and the negative contact surface are separated from each other as in the present invention (in other words, there is no member portion sandwiched between both surfaces). When the distance becomes long, a sufficient elastic deformation allowance including an elastic deformation allowance such as bending of the entire member can be expected. Therefore, even if the clearance during stacking is zero, the contact surface does not bite (without excessive frictional force), and stacking is easy to release at the panel usage site (easy to pick up one by one).

In addition, when both sides of “tenon” and “sane” are sandwiched between “vacant spaces” or “grooves” as in the prior art, if the clearance is small, deformation due to warping or shrinkage during corner member molding In addition, “tenon” or “sane” and “vacant space” or “groove” do not fit together, and stacking is not completed and the product may be tilted.
On the other hand, the positive contact surface and the negative contact surface are separated from each other as in the present invention (there is no member part sandwiched between both surfaces), so that even when the stacking clearance is zero, Will not be completed and the product will not tilt.
Therefore, it is suitable for unmanned handling in an automated line.

  In the corner member of the present invention, the column part has a peripheral wall that forms a substantially orthogonal corner, and the receiving part has a terrace-shaped bottom wall that projects horizontally inward from the lower or upper side of the peripheral wall. And an abutting surface for preventing displacement in the X direction or the Y direction is formed between the inner surface of the peripheral wall portion and the outer surface of the bottom wall, and between the upper surface of the peripheral wall portion and the lower surface of the peripheral wall portion. , A contact surface for preventing misalignment in the Y direction or the X direction can be formed.

As for the corner member of this invention, it is preferable that the convex part is formed in the said contact surface.
In this case, since the contact area between the contact surfaces is reduced, even if a large load is applied to the corner member, an excessive frictional force does not act between both surfaces, so that a situation where both surfaces are engaged with each other does not occur.
In addition, a convex part may be scattered on each inclined surface as a linear form, or as a dotted form. In the case of the dot shape, the contact area can be further reduced.

  The method for laminating a panel of the present invention is a method of laminating a panel-shaped product in a number of stages when transporting, storing, packing and / or transporting the panel-shaped product, A corner member is applied, and a plurality of the corner members are stacked.

  As is clear from the above description, according to the present invention, the clearance in the two lateral directions (panel plane direction) orthogonal to the stacking direction of the corner member is zero, so that the corner member can be stacked straight. . At this time, since the positive and negative movement restricting surfaces in the two lateral directions are not opposed to each other and formed at the isolated positions, even if a large load is applied to the corner panel, the surfaces bite each other. The phenomenon that fits can be prevented. Therefore, the destacking operation can be easily performed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
A corner member according to an embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3.
The corner member 1 has a column portion 10 that extends in the stacking (stacking) direction of the panel-shaped product P and receives the weight of the product, and a receiving portion 40 on which the corner of the panel-shaped product P is placed. The column part 10 and the wall part 40 are integrally produced by injection molding of a plastic material (for example, polypropylene or polyethylene). Each part is provided with a shift preventing means for preventing a shift in two lateral directions orthogonal to the stacking direction.
In the following description, the laminating direction (also referred to as the vertical direction) of the panel-shaped product is defined as the Z direction, and two lateral directions orthogonal to the Z direction are defined as the X direction and the Y direction. The XY plane is the surface of the panel product. The direction along one side of the panel-like product and the X direction, and the direction along the side perpendicular to the same piece are defined as the Y direction.

The column portion 10 will be described with reference mainly to FIGS. 1 and 3.
The column part 10 is a site | part which extends in the lamination direction (Z direction) of a panel-shaped product, and forms the substantially orthogonal corner. The column part 10 has the surrounding wall surface 11 which consists of the surface 11Y (ZY) which expands the surface 11X (ZX surface) which expands in a ZX surface, and the ZY surface orthogonal to the same surface. Furthermore, the upper surface 15 and the lower surface 17 projecting outward from the upper edge and the lower edge of the peripheral wall surface 11 (the −X direction and the −Y direction) and expanding in the XY plane, and outward from the both side edges of the peripheral wall surface 11 (− And a side surface 19 extending in the ZX plane and in the ZY plane.

  The peripheral wall surface 11 is a flat surface that expands the ZX plane and the ZY plane. The upper portions of the ZY surface 11Y and the ZX surface 11X are inclined surfaces that are inclined outward (−X direction and −Y direction) toward the upward direction (+ Z direction). Here, the surface 12x inclined in the −X direction of the ZY surface 11Y is called an upper X minus inclined surface (contact surface), and the inclined surface 12y inclined in the −Y direction of the ZX surface 11X is called an upper Y minus inclined surface (current Called tangent surface). The length (d1 in FIG. 3A) of the inclined surface 12 in the horizontal plane (XY plane) is preferably about 3 mm in consideration of the tolerance of the automatic stacking robot. In other words, the inclination angle of the inclined surface 12 with respect to the peripheral wall surface 11 is preferably larger than 135 °. In this example, the angle between the peripheral wall surface 11 and the inclined surface 12 is 170 °. Each inclined surface 12 is formed with a plurality (five in this example) of linear protrusions (ribs) 13 extending in the Z direction at a predetermined interval. The height of the convex portion 13 is substantially uniform along the Z direction, and the height is 1 mm as an example. However, the height of the lower portion of each convex portion 13 is low so that the upper surface of the convex portion 13 is the same surface as the peripheral wall surface 11.

  In the corners of the peripheral wall 11, a recess 14 is formed along the Z direction that is recessed deeper than the same surface. The concave portion 14 is for escaping between the corner of the panel-shaped product and the corner member when the corner of the panel-shaped product is placed on the receiving portion.

  On the outer surface of the ZX surface 11X of the peripheral wall surface 11, a plurality of ribs (not shown) extending in the Z direction and the X direction are provided upright. A plurality of ribs extending in the Z direction and the Y direction are also provided on the outer surface of the ZY surface 11Y of the peripheral wall surface 11. These ribs are for reinforcement. The height of each rib is equal to the width of the upper surface 15, the lower surface 17 and the side surface 19.

  The upper surface 15 is a flat surface extending in the XY plane. As shown in FIG. 1 and FIG. 3A, at a position near the intersection of the X-axis side and the Y-axis side of the upper surface 15 (outside of the recess 14 (+ X side and + Y side)) Are formed with step portions 20X and 20Y that are recessed downward (in the −Z direction). Each step portion 20 has a bottom surface 21 parallel to the upper surface 15, a side surface 22 on the intersection side (−X direction side, −Y direction side), and a side surface 23 on the opposite intersection side (+ X direction side, + Y direction side). . The side surface 22 on the intersection point side is a vertical surface that rises substantially perpendicularly from the bottom surface 21, and the side surface 23 on the anti-intersection point side is inclined in the anti-intersection direction (+ X direction, + Y direction) from the bottom surface 21 upward (+ Z direction). It has become an inclined surface. Here, the surface 23x inclined in the + X direction of the step portion 20X on the X-axis side is referred to as an upper X plus inclined surface (contact surface), and the surface 23y inclined in the + Y direction of the step portion 20Y on the Y-axis side is referred to. This is called the upper Y plus inclined surface (contact surface). The length (d2 in FIG. 3A) of the inclined surface 23 on the horizontal plane (XY plane) is preferably about 3 mm in consideration of the tolerance of the automatic stacking robot. The angle between the bottom surface 21 and the inclined surface 23 of each step 20 is 120 ° in this example. Each inclined surface 23 is formed with a plurality (two in this example) of linear convex portions 24 extending in the Z direction at a predetermined interval. The height of the convex portion 24 is substantially uniform along the Z direction, and the height is 1 mm as an example.

  The lower surface 17 of the column part 10 is a flat surface extending in the XY plane. As shown in FIGS. 2 and 3B, at the position near the intersection of the X-axis side and the Y-axis side of the lower surface 17 (outside of the recess 14 (on the + X side and + Y side)), at a position equidistant from the intersection point. Are formed with step portions 30X and 30Y that protrude downward (in the −Z direction). These step portions 30X and 30Y have substantially the same height as the depths of the step portions 20X and 20Y formed on the upper surface 15. Each step 30 has an upper surface 31 parallel to the lower surface 17, a side surface 32 on the intersection side (−X direction side, −Y direction side), and a side surface 33 on the opposite intersection side (+ X direction side, + Y direction side). . The side surface 32 on the intersection point side is a vertical surface falling substantially perpendicularly from the lower surface 17, and the side surface 33 on the anti-intersection point side is in the intersection direction (−X direction and −Y direction) from the lower surface 31 downward (−Z direction). ). Here, the surface 33x inclined in the −X direction of the step portion 30X on the X-axis side is called a lower X minus inclined surface (contact surface), and the surface inclined in the −Y direction of the step portion 30Y on the Y-axis side. 33y is called a lower Y minus inclined surface (contact surface).

The lower X minus inclined surface 33x of the step portion 30 of the lower surface 17 has the same length (Z direction length) as the upper X plus inclined surface 23x of the step portion 20 of the upper surface 15, and is formed at the same X direction position. ing. Similarly, the lower minus Y inclined surface 33y of the step portion 30 on the lower surface 17 has the same length (Z direction length) as the upper Y plus inclined surface 23y of the step portion 20 on the upper surface 15 and has the same Y direction position. Is formed. The length of the inclined surface 33 in the horizontal plane (XY plane) (d3 in FIG. 3B) is the length in the horizontal plane (XY plane) of the inclined plane 23 of the upper step 20 (d2 in FIG. 3A). It is preferable that it is about 3 mm similarly to. In this example, the angle between the lower surface 17 and each inclined surface 33 is equal to the angle of the inclined surface 23 of the upper surface 15 and is 120 °.
However, the vertical surface 22 of the upper surface step portion 20 and the vertical surface 32 of the lower surface step portion 30 are not necessarily formed at the same position in the X direction or the Y direction. The length of the upper surface step portion 20 may be longer than the length of the lower surface step portion 30, and the vertical surface 22 of the upper surface step portion 20 may be on the intersection side with respect to the vertical surface 32 of the lower surface step portion 30.

  Both side surfaces 19 are flat surfaces extending in the XZ plane and the YZ plane.

Next, the receiving unit 40 will be described with reference mainly to FIGS. 1 and 3.
The receiving part 40 is a terrace-shaped part projecting inward (+ X direction and + Y direction) from the lower side of the peripheral wall surface 11 of the column part 10. The receiving portion 40 has a bottom surface 41 that continuously extends from the lower edge of the peripheral wall surface 11 of the column portion 10 inward (+ X direction and + Y direction) and expands in the XY plane. As shown in FIG. 1, the bottom surface 41 is located below (−Z direction) below the lower surface 17 of the column part 10. Further, the receiving portion 40 protrudes downward (−Z direction) from the inner peripheral edge of the bottom surface 41, and protrudes downward (−Z direction) from both side edges and the inner peripheral surface 43 that widens the ZX surface and the ZY surface. And a side surface 45 extending the surface and the ZY surface. Furthermore, it has the outer peripheral surface 47 which protrudes in the downward direction (-Z direction) continuously from the lower surface 17 of the pillar part 10. As shown in FIG. The height of the side surface 45 is higher in the outer portion than in the inner portion.

  Specifically, the outer peripheral surface 47 is an inclined surface inclined inward (+ X direction and + Y direction) from the lower surface 17 of the column part 10. Here, the surface 47x inclined in the + X direction from the Y axis side of the lower surface 17 is called a lower X plus inclined surface (contact surface), and the surface 47y inclined in the + Y direction from the X axis side of the lower surface 17 is called the lower Y plus inclination. It is called a surface (contact surface). The length of the inclined surface 47 on the horizontal plane (XY plane) (d4 in FIG. 3B) is 3 mm, similar to the length of the upper inclined plane 12 on the horizontal plane (XY plane) (d1 in FIG. 3A). It is preferable that it is a grade. In this example, the angle between the lower surface 17 of the column part 10 and the inclined surface 47 is 100 ° (in other words, the inclined angle of the inclined surface 47 with respect to the vertical surface (the peripheral wall surface 11) is 170 °, Equal to the angle of the upper inclined surface 12). Further, the Z direction length of the inclined surface 47 is the same as the Z direction length of the inclined surface 12 of the peripheral wall surface 11. Further, the X direction positions of the lower X plus inclined surface 47x and the upper X minus inclined surface 12x of the column portion 10 are the same, and the Y of the lower Y plus inclined surface 47y and the upper Y minus inclined surface 12y of the column portion are the same. The direction position is the same.

  On the back surface of the bottom surface 41 of the receiving portion 40, a plurality of reinforcing ribs 42 extending in the X direction, the Y direction, and the XY direction are erected.

Next, the loading state of the corner member 1 will be described with reference to FIGS. The upper diagram in FIG. 4 shows the structure of the lower surface of the upper corner member 1A during loading with a broken line, and the lower diagram shows the structure of the upper surface of the lower corner member 1B. Both the directions in the X direction and the Y direction are the same. The member shown with the code | symbol P of FIG. 5 is a panel-shaped product.
When the corner member 1 is stacked, as shown in FIG. 5, the lower surface 17 of the column portion 10 of the upper corner member 1A is placed on the upper surface 15 of the column portion 10 of the lower corner member 1B. At this time, it is not necessary to completely contact the upper surface 15 and the lower surface 17 of each column portion 10 of the upper and lower corner members 1A, 1B. That is, even if the upper corner member 1 is dropped with a slight gap between the upper and lower surfaces, each inclined surface of the upper member 1 is guided to the corresponding inclined surface of the lower member, as shown below. Each surface abuts (see FIG. 4).
Upper X minus inclined surface 12x of the lower corner member 1B and lower X plus inclined surface 47x of the upper corner member 1A;
Upper Y minus inclined surface 12y of the lower corner member 1B and lower Y plus inclined surface 47y of the upper corner member 1A;
An upper X plus inclined surface 23x of the lower corner member 1B and a lower X minus inclined surface 33x of the upper corner member 1A;
Upper Y plus inclined surface 23y of lower corner member 1B and lower Y minus inclined surface 33y of upper corner member 1A.
In a state where all the inclined surfaces are in contact with each other, the deviation (clearance) between the contacting inclined surfaces is substantially zero.

  Note that the vertical surfaces 22 of the upper surface step portions 20X and 20Y of the lower corner member 1B do not need to be in contact with the vertical surfaces 32 of the lower surface step portions 30X and 30Y of the upper corner member 1A.

By such contact of the inclined surfaces, movement of the upper corner member 1A in each direction with respect to the lower corner member 1B is restricted as follows.
The movement of the upper corner member 1A in the + X direction is restricted by the contact between the upper X plus inclined surface 23x of the lower corner member 1B and the lower X minus inclined surface 33x of the upper corner member 1A.
The movement of the upper corner member 1A in the −X direction is restricted by the contact between the upper X minus inclined surface 12x of the lower corner member 1B and the lower X plus inclined surface 47x of the upper corner member 1A.
The movement of the upper corner member 1A in the + Y direction is restricted by the contact between the upper Y plus inclined surface 23y of the lower corner member 1B and the lower Y minus inclined surface 33y of the upper corner member 1A.
The movement of the upper corner member 1A in the −Y direction is restricted by the contact between the upper Y minus inclined surface 12y of the lower corner member 1B and the lower Y plus inclined surface 47y of the upper corner member 1A.

  Thus, the corner member 1 can be loaded straight by setting the clearances between the inclined surfaces in the + X and −X directions and the + Y and −Y directions to zero.

  Furthermore, as shown in FIG. 6, the inclined surfaces 23x and 33x that restrict the + X direction and the inclined surfaces 12x and 47x that restrict the −X direction are not opposed to each other, and a certain amount of the Y direction is between them. There is a discrepancy (separation) Dy. Similarly, the inclined surfaces 23y and 33y that regulate the + Y direction and the inclined surfaces 12y and 47y that regulate the -Y direction do not face each other, and there is a certain amount of X direction discrepancy (separation) Dx between the two. Exists.

  On the other hand, in the corner member 100 shown in FIG. 7 presented in the prior art, in the X direction and the Y direction, the surface that restricts the + direction and the surface that restricts the − direction face each other. Specifically, these surfaces are the opposite outer surface of the “tenon” 111 or “sane” and the opposite inner surface of the void 113 or groove, and both are in the same X-direction position or Y-direction position. And relatively close. In this case, assuming that the clearance in the X direction and the Y direction between the upper and lower corner members is zero, both outer surfaces of the tenon 111 and both inner surfaces of the cavity 113, or both outer surfaces of the tongue and both inner surfaces of the groove Bite and become difficult to leave. This is because when the distance between the two contact surfaces is shortened, the tenon or sane subjected to the contact surface pressure has insufficient elastic deformation due to the compression of the tenon or sane itself. This is because it can only be expected.

  In the present invention, as shown in FIG. 6, in the X direction and the Y direction, the + direction contact surface and the − direction contact surface do not face each other and are separated from each other. In this case, a sufficient elastic deformation allowance including an elastic deformation allowance such as bending of the entire member can be expected. For this reason, even if the clearance during stacking is zero, it adapts due to elastic deformation, so the contact surface does not bite (without excessive frictional force) and it is easy to release stacking at the site where the panel is used (pick up one by one) Cheap).

In addition, when both sides of “tenon” and “sane” are sandwiched between “vacant spaces” or “grooves” as in the prior art, if the clearance is small, deformation due to warping or shrinkage during corner member molding In addition, “tenon” or “sane” and “vacant space” or “groove” do not fit together, and stacking is not completed and the product may be tilted.
On the other hand, by making the plus direction contact surface and the minus direction contact surface apart from each other as in the present invention (there is no member or part sandwiched between both surfaces), it is difficult to cause stacking problems. Lateral misalignment can be eliminated and stacking can be released without biting. Therefore, even if the clearance at the time of stacking is zero, even if there is some deformation of the member, the situation that the stacking is not completed and the product tilts does not occur.

Furthermore, when the inclined surfaces contact each other, the upper inclined surfaces 12x, 12y, 23x, and 23y are formed with linear convex portions 13 extending in the Z direction, so that the surfaces do not come into surface contact with each other, The upper surface of the convex portion of one inclined surface is in contact with the other inclined surface, and the contact area between the two is reduced. For this reason, even if a large load is applied to the corner member, an excessive frictional force does not act between both surfaces, so that a situation where both surfaces are engaged with each other does not occur.
It should be noted that the same effect can be obtained even if the convex portions are made dotted, instead of the linear convex portions 13 extending in the Z direction, and scattered on each inclined surface.
