A structure having a buffering function while being held in position is known (see Patent Document 1).

China Utility Model Notice 20102010100Y Specification

  Since the cushioning function as a cushioning material is small in the material and structure used for such a returnable box, the function and quality of the product may not be maintained from shock and vibration in situations where the handling of the returnable box is poor. In order to transport products to their destinations at low cost while maintaining the quality of products even under these circumstances, there is a need for a returnable box designed to further improve buffering properties.

  In order to solve the above-described problems, the present invention provides a packaging device that improves buffering properties for protecting a product and improves handling properties (such as improved work efficiency).

To solve the above SL problems, the packaging device of the present invention, the side walls, the outer be convex portion of the side wall becomes concave on the inside of the side wall, is convex to the inside of the side wall in its cross section The part is a shape that repeats unevenness by connecting a plurality of bent shapes that are concave on the outside of the side wall, and the inner ridge part that is formed in the vertical direction to erect the part that protrudes inside the side wall A portion protruding outward from the side wall is an outer ridge formed in the vertical direction, and the inner ridge is formed with the wall-side engagement portion in the vertical direction. By being characterized, it can be disassembled by removing the side wall or the like except when using the packaging, and the storage form when not in use and the packing form when returning are compact. In addition, since the assembly is detachable and can be taken in and out, workability is good. Also, since the side wall is formed in an uneven shape, the strength as a peripheral wall member is high, and if the outer ridge is a place where impact or pressure from the outside is applied, it has a buffering function to relieve the force, and A predetermined distance can be provided between the portion where the tray is held (inner ridge) and the portion where the impact or pressure is applied (outer ridge) by unevenness, so that it can be stored in the storage space. Thus, it is possible to reduce the influence of the force on the tray, and to improve the cushioning property for the product accommodated in the tray, and to provide a packaging device that can be transported so as to maintain the function and quality of the product.

  Moreover, in order to solve the said subject, in the packing apparatus of this invention, it can also be set as the triangular wave shape, a sine wave shape, a sawtooth wave shape, or a square wave shape as the bending form of the said side wall. In addition, the vertical distance between the wall-side engaging portions is set so that the tray stored in the storage space portion is in the vertical direction and does not contact the upper surface of the other tray or the pallet. Thereby, since the buffer member which is another member is not used, storage work becomes favorable. In addition, since the tray is independently held by the side wall, it is not affected by other loads and does not adversely affect the buffering function of the tray itself, so that it is possible to maintain the function and quality of the product. A packaging device can be provided. In the flange portion of the tray, a rib portion having a thickness larger than that of the flange portion is integrally formed on an outer peripheral edge engaged so as to be able to be put in and out so as to enter the wall side engaging portion. By doing so, the strength of the tray can be increased, and the breakage of the tray due to the force applied to the engagement can be prevented.

  Moreover, in order to solve the said subject, in the packing apparatus of this invention, the said side wall is arrange | positioned between the column-shaped support | pillar member which should be arrange | positioned as said inner side protrusion part, and this adjacent support | pillar member. And is formed of a side plate member that is detachably connected to the column member and is detachably connected to the column member. In addition to the same effects as described above, the side wall is divided into a support member and a side plate member. it can. Further, when the column member and the side plate member are connected by inserting the side edge of the side plate member into a connection groove formed in the vertical direction of the column member, the column member and the side plate member Assembling of the side wall by means of can easily be performed, and workability is good.

  Moreover, in order to solve the said subject, in the packing apparatus of this invention, the said support | pillar member is the state which the said flange part of the said tray which accommodated the said product in the said product accommodating part engaged with the said wall side engaging part. The side plate member is formed of a flexible material having flexibility and a buffering action against a force from the lateral direction. Since the strut member is made of a rigid material and the side plate member is made of a flexible material having a buffer function even when a force is applied to the side wall from the outside, the force deforms the side plate member. Even if it is made to do, since this side plate member can be elastically deformed, it is difficult to transmit the influence of force to the tray, and the shock-absorbing property for protecting the product can be further enhanced.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded view of a basic form of a packing apparatus according to an embodiment of the present invention. FIG. 2 is an overall view in which the tray of the packaging device is omitted. In FIG. 1, a packing device 1 includes a pallet 2 used for transportation, a side wall portion 3 disposed so as to surround a part of an upper surface 2 a of the pallet 2 from the circumferential direction, and a ceiling placed on the side wall portion 3. And a plate 4.

  Further, as shown in the figure, in the inner storage space S surrounded by the top plate 4, the side wall 3, and the pallet 2, an appropriate number of trays 5 that store the products P are stored.

  The pallet 2 shown in the figure is formed in a rectangular shape (in this figure, it may be a rectangle or a square) as a plan view. The pallet 2 is made of a material (generally made of a synthetic resin and made of metal, wood, paper, etc.) that can withstand loads and impacts corresponding to the weight of the product P during storage and transportation. It is formed.

  Further, a concave lower insertion portion 2b is provided near the peripheral edge 2e of the four sides of the upper surface 2a for forming a part of the storage space S. By inserting the lower end side of the side wall portion 3 into the lower insertion portion 2b, the side wall portion 3 is detachably connected and erected. Thereby, a part (inner side) of the upper surface 2 a of the pallet 2 is surrounded by the side wall portion 3 from the circumferential direction. Thus, the side wall part 3 is assembled by being inserted into the pallet 2, and can be easily extracted and thereby disassembled and assembled.

  Further, the pallet 2 is formed with a predetermined thickness so that an installation surface 2c on a floor surface (not shown) or the like is provided on the lower side. A fork hole 2d is provided between the upper surface 2a in the thickness direction and the installation surface 2c. The fork hole 2d is used when the fork is moved by inserting a fork of a forklift (not shown).

  The side wall portion 3 is composed of a plurality (four in this example) of side walls 3a to be inserted into the lower insertion portions 2b provided on the four sides of the pallet 2. As shown in FIG. 3, the side wall 3 a has a waveform (triangular wave shape) having unevenness (zigzag shape) due to a plurality of bent forms in a cross section thereof so that the multiple unevenness is alternately and continuously repeated. It is integrally formed to present. In addition, the material used for this integral formation can use the material similar to the pallet 2. FIG.

  The side wall 3a is erected by inserting the lower end side into the lower insertion portion 2b for each side of the pallet 2. Further, the side wall 3a can be easily extracted from the lower insertion portion 2b. As a result, the side wall 3a can be disassembled and assembled. The lower insertion portion 2b is formed in a zigzag groove shape that opens upward so that the lower end side of the zigzag shape of the side wall 3a is inserted. In addition, the side wall 3a has a buffering function to relieve the force due to impact or pressing from the outside in the standing state.

  In the side wall 3a, a portion that protrudes outside the side wall 3a in the cross section is concave inside the side wall 3a, and a portion that protrudes inside the side wall 3a repeats irregularities that become concave outside the side wall 3a. Shape. A portion that protrudes inward of the side wall 3a is formed as an inner ridge 3b that bulges toward the storage space S side that is the inner side of the side wall 3a and that is formed in the up-down direction of the side wall 3a. . In addition, a portion that protrudes outward from the side wall 3a is formed as an outer ridge portion 3c that bulges outward on the side wall 3a opposite to the storage space S side and is formed in the vertical direction.

  The shape of the side wall 3a in FIG. 3 is a so-called triangular wave shape, but as a modification thereof, it may be formed in a sine wave shape as shown in FIG. 4 (a) or as shown in FIG. 4 (b). It may be formed in a rectangular wave shape, or may be formed in a sawtooth wave shape as shown in FIG. 4 (c). In short, a portion that protrudes outside the side wall 3a becomes concave inside the side wall 3a, and the side wall The portion that protrudes inward of 3a has a shape in which concave and convex portions that become concave on the outside of the side wall 3a are repeated, and any portion that has a function of buffering the force F caused by pressing from outside or impact.

  In addition, the top 3d on the side of the inner ridge 3b, which is the inner wall of the side wall 3a according to these examples, is engaged as a multi-stage wall-side engaging portion in which a flange 5c of the tray 5 described later enters and engages. Concave portions 3e are formed at predetermined intervals in the vertical direction in which the side wall 3a is erected. The engagement recess 3e is formed in a groove shape so as to open inward in the storage space S side with a width corresponding to the thickness of the flange 5c in the lateral direction perpendicular to the vertical direction in which the side wall 3a is erected. Notches are formed. The vertical interval between the engagement recesses 3e is set so that the tray 5 stored in the storage space S is in the vertical direction and does not come into contact with the other tray 5, the upper surface 2a of the pallet 2, and the top plate 4.

  As another example of the shape of the side wall 3a, as shown in FIG. 20 (a), an inner ridge 3b bulges on the inner side of the plate-like body in the cross section, and an outer ridge on the outer side. The part 3c is bulged. The outer ridge 3c and the inner ridge 3b may be displaced in the lateral direction, or may be positioned at the same location in the lateral direction as shown in FIG. 20 (b). Further, as shown in FIG. 20 (c), the flange portion 5c of the tray 5 is arranged in parallel with a predetermined interval in the vertical direction inside the plate-like body 3f in its transverse section so that it can slide. An engagement recess 3e can be formed between the pair of guide protrusions 3g. Further, as shown in FIG. 21, the engaging recess 3e may be formed with a portion penetrating in a hole shape in the thickness direction of the side wall 3a.

  For example, when the pallet 2 is square, the four side walls 3a can be formed in the same shape as shown in FIG. 5, thereby improving workability during packaging. Can do. Moreover, it is easy to put together because there is the same shape when returning. Furthermore, since the engaging recess 3e does not protrude from the wall surface of the side wall 3a and is concave, there is no obstacle even when the side walls 3a are overlapped in the thickness direction. Furthermore, if the cross-sectional shape of the side wall 3a is a triangular wave shape (FIG. 3), a sine wave shape (FIG. 4 (a)), or a sawtooth wave shape (FIG. 4 (b)), the side walls 3a can be closely stacked without any gap. This can contribute to a reduction in storage space. Further, the convex portion on the outside of the side wall 3a is concave on the inner side of the side wall 3a, and the convex portion on the inner side of the side wall 3a has a shape that repeats the concave and convex portions that are concave on the outer side of the side wall 3a. It is also possible to provide the hinge means 3h at the connecting portion of the unevenness so that the unevenness can be expanded and contracted in the lateral direction.

  Further, in a form in which the upper surface 2a of the pallet 2 is surrounded by the side wall 3a from the circumferential direction, as shown in FIG. 1, in order to closely surround the side edge 3a1 of the side wall 3a adjacent in the circumferential direction, FIG. As shown by, the dimension of the interval L2 from the top 3d of the inner ridge 3b to the side edge 3a1 is approximately halved with respect to the dimension of the interval L1 between the adjacent inner ridges 3b.

  As shown in FIGS. 1 and 2, the top plate 4 is placed on the side wall portion 3 erected. The top plate 4 is composed of a top plate main body 4a formed in a plate shape, and the upper surface of the side wall 3a is inserted into the back surface of the top plate main body 4a in the same manner as the lower insertion portion 2b of the pallet 2. The upper insertion portion 4b is formed in a groove shape so as to have a zigzag shape and open downward.

  And the top plate 4 can be mounted by detachably connecting to the upper insertion portion 4b of the top plate 4 so as to insert the upper end side of the side wall 3a. Thus, since the upper side insertion part 4b and the upper end side of the side wall 3a are insertion forms, the top plate 4 can also be disassembled and assembled. In addition, the material used for the top plate 4 can use the material similar to the pallet 2 and the side wall 3a.

  The tray 5 is made of an elastically deformable material such as synthetic resin (plastic) and is integrally formed by a known molding method. As shown in FIG. 6, the basic form is to hold the product P in a regulated state so that the product P is accommodated at a central position of the tray main body 5 a so that there is no backlash at a predetermined position and there is no backlash. In order to provide a holding function and a buffering function for relieving a force caused by vibrations applied to the product P during transportation, the product housing portion 5b formed in a concave shape with a bottom opened is provided.

  Moreover, it has the flange part 5c projected outward from the circumference | surroundings of the product accommodating part 5b continuously. The flange portion 5c enters and engages with a groove-like engagement recess 3e in the side wall 3a. This engaged state is held so as to restrict at least the downward movement (desirably in the vertical direction) of the tray 5 in a state where the flange portion 5c enters the engagement concave portion 3e. In addition, the engaging recess 3e can engage with the flange 5c so that it can be inserted and removed by sliding the tray 5 in the horizontal direction and allowing the flange 5c to enter the plurality of engaging recesses 3e. Thereby, the tray 5 can be dispersed and held by the plurality of engaging recesses 3e.

  Further, in the flange portion 5c of the tray 5, a rib portion 5d having a thickness larger than that of the flange portion 5c is integrally formed on the outer peripheral edge entering the engaging recess 3e. Thereby, the strength of the tray 5 can be increased, and the breakage of the tray 5 due to the force applied to the engagement can be prevented.

  Further, the inner wall 5b1 of the product storage portion 5b of the tray 5 is formed so that the bottom 5b2 side is slightly narrower than the opening 5b3 due to a predetermined gradient (draft gradient) at the time of molding, so that the product storage portion 5b overlaps. When being stacked, a part of the upper product storage portion 5b (upper side of the inner wall 5b1) enters the lower product storage portion 5b.

  Further, by forming the inner wall 5b1 so as to provide a predetermined tightening margin with respect to the dimensions in the front-rear direction Y and the width direction X of the product P shown in FIG. A buffer function is provided. The depth D of the product accommodating portion 5 b shown in FIG. 6 is formed larger than the height dimension H of the product P. In addition, the concave manual insertion / extraction part 5b4 for taking out the product P accommodated in the product accommodating part 5b is formed in the inner side wall 5b1 corresponding to the front-back direction Y and the width direction X side of the product P. .

  Examples of the product P include a copying machine, a facsimile, and a printer. In this example, it will be described as a document reader having a weight of about several kilograms constituting a copying machine. The product P has a substantially rectangular parallelepiped shape, and has a predetermined height direction H as a maximum dimension, a length dimension in the front-rear direction Y, and a width dimension in the width direction X. When being accommodated in the tray 5, the tray 5 is accommodated in a regulated state so that there is no backlash and the position does not shift.

  The planar view form of the tray 5 is formed in a rectangular shape, and the flange portion 5c has a linear peripheral edge 5e. This facilitates a sliding operation in a packing operation described later, and a plurality of engaging recesses 3e are engaged with the peripheral edge 5e. In addition, the planar view form of the tray 5 is an example corresponding to the planar view form of the product P accommodated in the product accommodating portion 5b. In this case as well, the plurality of engaging recesses 3e are engaged with the flange portion 5c formed in a polygonal shape in plan view and a circular shape in plan view.

  Next, the packing operation of the packing apparatus 1 will be described. As shown in FIG. 7, two bodies on the opposite sides of the pallet 2 (not shown in the figure) are arranged so as to hold two sides on the opposite side of the flange portion 5c in the tray 5 containing the products P. First, the side wall 3a is erected. Then, while sliding the tray 5 containing the product P from the lateral direction between the opposing side walls 3a, the flange 5c of the tray 5 is inserted into the engaging recess 3e of the side wall 3a, and the engaging recess 3e The tray 5 is stored in the storage space portion S at a predetermined position by engaging the flange portion 5c so that it can be inserted and removed. After the necessary number of trays 5 are appropriately stored in the vertical direction in this way, the remaining side wall 3a is erected and enclosed so as to form the storage space S, and thereafter the top plate 4 is placed on the side wall 3a. The packaging operation is completed by placing the packaging device 1.

  As another example of this packing operation, as shown in FIG. 8, the pallet 2 (not shown in the figure) intersects so as to hold two intersecting sides of the flange portion 5c in the tray 5 containing the products P. Two side walls 3a are first erected on the two sides. The flange 5c of the tray 5 is inserted into the engagement recess 3e of the side wall 3a while sliding the tray 5 containing the product P with respect to the one side wall 3a from the horizontal direction. The flange 5c of the tray 5 is engaged with the engagement recess 3e of the side wall 3a by sliding the portion 5c so that the flange 5c abuts against the engagement recess 3e of the side wall 3a positioned forward in the sliding direction. The tray 5 is stored in the storage space S at a predetermined position by being engaged so as to enter 3e. After the necessary number of trays 5 are properly stored in the vertical direction in this way, the remaining side walls 3a are erected so as to form the storage space portion S, and then the top plate 4 is placed on the side walls 3a. Thus, the packing operation is completed and the packing apparatus 1 is obtained.

  As another example of this packing operation, as shown in FIG. 9, the pallet 2 (not shown in this figure) is held so as to hold three sides located in a U-shape in the tray 5 containing the products P. First, side walls 3a are erected on the three sides. Then, while sliding the tray 5 containing the product P between the opposite side walls 3a of the three side walls 3a from the horizontal direction, the flange portion 5c of the tray 5 is inserted into the engaging recess 3e of the side wall 3a, The engaging recess 3e and the flange portion 5c are engaged with each other so as to be able to be inserted and removed, and further, the flange portion 5c of the tray 5 is slid until the flange portion 5c comes into contact with the engaging recess 3e of the side wall 3a positioned forward in the sliding direction. The tray 5 is stored in the storage space S at a predetermined position by engaging the engaging recess 3e of the side wall 3a. After the necessary number of trays 5 are appropriately stored in the vertical direction in this way, the remaining side wall 3a is erected and enclosed so as to form the storage space S, and thereafter the top plate 4 is placed on the side wall 3a. As a result, the packing operation is completed and the packing apparatus 1 is obtained. As described above, the tray 5 is slid and stored on two side walls 3a arranged in parallel, two side walls 3a arranged in an L shape, and three side walls 3a arranged in a U-shape. . When the four sides are finally closed, the remaining side wall 3a used for the closing can be provided with no engagement recess 3e. In this case, a buffer member (not shown) such as a foamed polystyrene or a bubble cushioning material that is generally used can be interposed between the tray 5 and the side wall 3a that does not have the engagement recess 3e.

  As an example, as shown in FIG. 8, when the side edge 3a1 of the side wall 3a adjacent in the circumferential direction is in close contact, the corner 5c1 of the flange portion 5c of the tray 5 has two side walls. The holding function of the tray 5 can be enhanced by being engaged and held by the two engaging recesses 3e provided on the inner protrusion 3b of 3a.

  FIG. 10 is a partial perspective view of the packaging device in which the top plate 4 in a state where the tray 5 is accommodated in the vertical direction by the packaging operation is omitted, and FIG. 11 is a side view from the direction C of FIG. . When the packaging operation is completed and assembled as the packaging device 1 in this manner, the trays 5 stored vertically are prevented from interfering with each other (contact, contact, etc.). In addition, the packing device 1 is advantageous in that it does not interfere with the upper surface 2a of the pallet 2 and the top plate 4 that is omitted, thereby eliminating the need for a buffer member as a separate member. In addition to the packaging use in which the tray 5 is stored in the storage space S as described above, the packaging device 1 is removed from the pallet 2 and the tray 5 removed from the side wall 3a after being sent to a predetermined transport destination. The side wall 3a can be collected for reuse.

  As shown in FIG. 15A, the side wall 3a configured in this manner is in a state in which the tray 5 is stored in the storage space S while the flange portion 5c of the tray 5 is held by the engaging recess 3e. Even if a force F due to external pressure or impact is applied to the outer protrusion 3c of the side wall 3a, the side wall 3a has a buffering function. Therefore, even if the force F deforms a part of the side wall 3a, the side wall 3a By elastically deforming, the influence of the force F can hardly be transmitted to the tray 5.

  Next, a modified example of the packaging device will be described. In this modification, as shown in FIGS. 12 to 14, the side wall 3a having the zigzag wave shape formed integrally is positioned on the inner ridge portion 3b protruding toward the storage space portion S side of the side wall 3a. A columnar column member 7 to be formed separately, and a columnar auxiliary column member to be formed separately, which are to be positioned on the outer ridge 3c projecting outward from the inner ridge 3b on the side wall 3a. 8 and a side plate 9 disposed between the adjacent column member 7 and the auxiliary column member 8 and connecting the column member 7 and the auxiliary column member 8. These support members 7, auxiliary support members 8, and side plates 9 are connected so as to be disassembled and assembled. In this example, the auxiliary plate member 8 and the side plate 9 are connected to each other as the side plate member 10.

  As shown in FIG. 12, the column member 7 is composed of a column body 7a formed in a columnar shape, and the flange portion 5c of the tray 5 enters in the vertical direction of a part of the side surface 7b of the peripheral surface of the column body 7a. Engaging recesses 3e to be engaged are formed at predetermined intervals. The engaging recess 3e is cut out in a groove shape so as to open inward in the storage space S side with a width corresponding to the thickness of the flange 5c in a lateral direction perpendicular to the standing direction of the side wall 3. It is formed. The vertical interval between the engagement recesses 3e is set so that the tray 5 stored in the storage space S is in the vertical direction and does not come into contact with the other tray 5, the upper surface 2a of the pallet 2, and the top plate 4.

  The side surface 7b of the column main body 7a in which the engagement recess 3e is formed is a surface facing the inside on the storage space S side in the assembled state as the side wall 3a, and this surface is formed on the top 3d of the inner protrusion 3b. It will correspond. Further, on both side surfaces 7c intersecting with the engaging recess 3e, a groove-like connection groove 7d is formed that opens sideways in the vertical direction.

  The auxiliary strut member 8 is composed of an auxiliary strut body 8a formed in a columnar shape, and a groove-like connecting groove that opens sideways in the vertical direction on both side surfaces 8c of a part of the peripheral surface of the auxiliary strut body 8a. 8d is formed. Further, the side plate 9 is formed in a band plate shape with a thickness that enters the connection grooves 7d and 8d. Thus, the side edge of the side plate 9 can be inserted into the connecting grooves 7d and 8d while sliding from the vertical direction.

  The column member 7, the auxiliary column member 8, and the side plate 9 are erected by being inserted into the lower insertion portion 2 b of the pallet 2 in the same manner as the integrally formed side wall 3 a. The lower insertion portion 2b is formed in a concave shape with a cross-sectional shape corresponding to the cross-sectional shape of the column member 7 and the auxiliary column member 8 because the lower end side of the column member 7 and the auxiliary column member 8 is inserted. In addition, since the lower end side of the side plate 9 is inserted, it is formed in a concave shape with a cross-sectional shape corresponding to the cross-sectional shape of the side plate 9. And in order to assemble the side wall 3a by this support | pillar member 7, the auxiliary | assistant support | pillar member 8, and the side plate 9, the support | pillar member 7 and the auxiliary | assistant support | pillar member 8 are inserted in the predetermined position of the lower side insertion part 2b, and are made to stand. Then, it is assembled by inserting the side edge of the side plate 9 into the connecting grooves 7d and 8d while sliding the side plate 9 downward from above between the adjacent column members 7 and auxiliary column members 8. Since the packing operation according to this modification can be performed as described above based on FIGS. 7 to 9, the description according to this example is omitted.

  In addition, at least the column member 7 (the auxiliary column member 8 may be formed of the same material) has the flange portion 5c of the tray 5 in which the product P is accommodated in the product accommodating portion 5b of the tray 5 in the engagement recess 3e. It is formed of a rigid material having sufficient mechanical properties with respect to the load of the tray 5 when stored in the engaged state. On the other hand, the side plate 9 has flexibility and is formed of a flexible material having a buffer function against an impact from the lateral direction (horizontal direction). Examples of the material of the support member 7 include metals such as aluminum and stainless steel. Examples of the material of the side plate 9 include elastic PVC, polystyrene, ABS, polyethylene, etc., such as elastic rubber and synthetic resin.

  As shown in FIG. 15 (b), the side wall 3a composed of the column member 7, the auxiliary column member 8, and the side plate 9 configured as described above has a storage space while the flange portion 5c of the tray 5 is held by the engagement recess 3e. In the state where the tray 5 is accommodated in the portion S, the column member 7 is formed of a rigid material even if a force F due to external pressure or impact is applied to the auxiliary column member 8 which is the outer protruding portion 3c of the side wall 3a. In addition, since the side plate 9 is formed of a flexible material having a buffering function, even if the force F deforms the side plate 9, the side plate 9 is elastically deformed, so that the influence of the force F is influenced by the tray 5. It can be difficult to communicate.

  As a modification of the side wall 3, as shown in FIG. 16, instead of the side plate member 10 connecting the auxiliary column member 8 and the side plate 9, the auxiliary column member 8 is eliminated and disposed between the column members 7. Only the side plate 9a is used as the side plate member 10a. The side plate member 10a is integrally formed in a substantially V shape in the cross section. And the support | pillar member 7 is inserted in the predetermined position of the lower side insertion part 2b, and is made to stand. Thereafter, while the side plate member 10a is slid downward from above between the adjacent column members 7, the side wall 3a is assembled by inserting the side edges of the side plate member 10a into the connection grooves 7d and 8d. The packaging work according to this modification can be performed in the same manner as described above based on FIGS. 7 to 9, and other configurations according to this example are the materials of the configurations in the other embodiments described above.
