[ embodiment 1 ]

[1-1 construction of holding jig 1 ]

The holding jig 1 of embodiment 1 is configured to be capable of holding the holding object M. The holding object M is not particularly limited, but the container 101 is preferable. When the object to be held M is the container 101, the container 101 may be exemplified by a container 101 having a main body 102 with an upper side opened, and having a flange 103 extending outward on an upper end (upper edge) side of the main body 102. In the container 101, an opening 104 of the body 102 is formed inside the flange 103.

The holding jig 1 includes a penetration portion 2 through which the object M is penetrated, and a support portion 3 for supporting the object M outside the penetration portion 2. The holding jig 1 has a holding structure 4 for holding the holding object M. The holding structure 4 is a structure including the support portion 3 and the insertion portion 2, and is a structure in which the object to be held M is inserted into the insertion portion 2 and a predetermined portion of the object to be held M is supported by the support portion 3.

(support portion 3)

The support portion 3 is defined as a portion for supporting the holding object M. For example, as shown in fig. 1 and A, B of fig. 2, the holding object M is supported by a structural portion in which the constituent members 5 are arranged in a ring shape as described later, and thus the support portion 3 is defined as a ring-shaped structural portion in which the constituent members 5 are arranged in a ring shape. The support portion 3 is formed outside the insertion portion 2.

(penetration portion 2)

The insertion portion 2 is defined as a space portion 106, and the space portion 106 is formed with a support portion 3 around the space portion to pass through the object M. In the example shown in fig. 1, a space inside the annular structure portion in which the constituent members 5 are arranged in an annular shape is determined. The insertion portion 2 is defined as a space portion 106 through which the object M to be held passes inside the support portion 3 when the object M to be held is supported by the support portion 3.

(substrate 6)

The holding jig 1 is provided with a substrate 6 for supporting the constituent member 5 from below. The substrate 6 is provided with a through hole 7. In the example of fig. 1, the through hole 7 is formed so as to penetrate the substrate 6 in the thickness direction of the substrate 6 and allow the holding object M to pass under the penetration portion 2. The material of the substrate 6 is not particularly limited, and may be metal, plastic, wood, glass, ceramic, or the like, but from the viewpoint of excellent strength, the substrate 6 is preferably made of metal. In the example of A, B in fig. 1 and 2, the shape of the outline of the substrate 6 is a tongue shape, but this is only an example, and other shapes such as a rectangular shape and a circular shape may be used. The substrate 6 is described using an example in which the through-holes 7 are provided, but the shape of the substrate 6 is not limited thereto. For example, the substrate 6 may be formed in a cut-in shape from the outside toward the inside so as to be capable of passing through the holding object M, or may have other structures. In the present specification, "the direction toward the inside of the through hole 7" refers to the direction toward the inside of the insertion portion 2, and "the direction toward the outside of the through hole 7" refers to the direction toward the outside of the insertion portion 2.

(constituent Member 5)

In the holding jig 1, a plurality of constituent members 5 are arranged in a ring shape. Here, the annular arrangement means a state in which the substrate 6 is arranged so as to surround the periphery of the reference position when the thickness direction of the substrate is the line of sight direction and when the center position CT of the through-hole 7 is the reference position. In the case of the annular arrangement, the case where the direction away from the reference position (the direction extending outward from the reference position along the surface normal to the thickness direction of the substrate 6) is the line of sight direction includes the case where the adjacent plurality of constituent members 5 overlap, the case where at least a part of the adjacent plurality of constituent members 5 separate, and the case where at least a part of the adjacent plurality of constituent members 5 contact.

(shape and layout of constituent Member 5)

The shape of the constituent members 5 is not particularly limited, but in the example of a of fig. 2, the plurality of constituent members 5 are formed in a shape (tapered shape of the tip) tapered toward the inside of the through hole 7 in a plan view of the substrate 6. The shape of the component member 5 shown in a of fig. 2 is formed in a shape obtained by removing a concentric sector (small sector) from a sector (large sector) in a plan view of the holding jig 1 (the same as the case where the thickness direction of the support plate is the line of sight direction). In this example, the constituent member 5 has a side surface (inner side surface 12) near the insertion portion 2, a side surface (outer side surface 13) far from the insertion portion 2, and a side surface (lateral side surface 14) facing the adjacent constituent member 5, the inner side surface 12 is formed in a concave curved surface shape (arc surface shape in the example of a in fig. 2), the outer side surface 13 is formed in a convex curved surface shape (arc surface shape in the example of a in fig. 2), and the lateral side surface 14 is formed in a flat surface shape.

In the example of a of fig. 2, the plurality of constituent members 5 are formed in substantially the same shape, and the layout of the plurality of constituent members 5 is a layout configured in a circular shape as a whole. However, this is merely an example, and the layout of the plurality of constituent members 5 may be rectangular, or the like, to approximate a shape other than a circular shape.

In fig. 2 a, the position of the component member 5 is a position in a state (inner displacement state) in which the component member 5 is displaced in the direction toward the inner side of the through hole 7. In the inner displacement state, the lateral sides 14 of adjacent constituent members 5 are in contact. The constituent member 5 has a tapered front end shape, whereby the movable constituent member 8 is restricted from being displaced further inward from the position in the inward displaced state.

(Movable component 8)

At least a part of the plurality of the constituent members 5 is a movable constituent member 8. The movable component member 8 is a component member 5 (in a non-fixed state) that is disposed so as to be displaceable in at least one direction of a direction toward the inside of the through-hole 7 and a direction toward the outside of the through-hole 7 in a plan view of the substrate 6. In the example of a of fig. 2, the plurality of constituent members 5 are each movable constituent members 8. In this example, the movable component member 8 is displaceable in either one of the direction toward the inside of the through hole 7 and the direction toward the outside of the through hole 7.

The movable component member 8 is capable of being displaced in the plane direction of the substrate 6. The fact that the displacement in the surface direction of the substrate 6 is possible means the following concept: not only the case where the movable component member 8 is movable in the plane direction but also the case where the movable component member 8 is movable in a slightly different direction with respect to the plane direction.

(stress applying mechanism 9)

The holding jig 1 has a stress applying mechanism 9. The stress applying mechanism 9 applies stress to the movable component member 8 in correspondence with the displacement of the movable component member 8. For example, the stress applying mechanism 9 is constituted by an elastic member 10. In the example of fig. 2, the elastic member 10 is formed in a ring shape, and is disposed so as to surround the plurality of constituent members 5 disposed in the ring shape. The expansion and contraction direction of the elastic member 10 is along the groove 11 of the constituent member 5. On the outer side surface 13 of the constituent member 5, a groove 11 extending along the outer side surface 13 is formed, and the position of the groove 11 is substantially uniform for any of the constituent members 5. The elastic member 10 is disposed so as to pass through the inside of each of the grooves 11 of the plurality of groove 11 members. In a natural state in which the holding jig 1 is not provided with the holding object M, the movable component member 8 (all component members 5 in a of fig. 2) is displaced inward of the through hole 7 by the restoring force of the elastic member 10 (an inward displaced state).

In the present specification, the state after the movable component 8 is displaced toward the outside of the through hole 7 is referred to as an outside displacement state, and the state after the movable component 8 is displaced toward the inside of the through hole 7 is referred to as an inside displacement state.

(elastic member 10)

The elastic member 10 is not particularly limited, and may be, for example, rubber or a spring, but is preferably a spring from the viewpoint of easily designating the approximate directivity to the restoring force and easily forming a state of applying stress in a specific direction to the constituent member 5. The material of the elastic member 10 is not particularly limited, but is preferably metal from the viewpoint of strength.

(Displacement control of the movable constituent member 8 based on the stress applying mechanism 9)

The displacement of the movable component member 8 (the displacement of all the component members 5 in embodiment 1) can be controlled as follows by the stress applying mechanism 9. When the holding object M passes through the through-hole 7, the holding object M also passes through the insertion portion 2. When the dimension (dimension in a plan view) of the holding object M exceeds the insertion portion 2 in the state of being displaced inward, the holding object M applies a pressing force to the plurality of constituent members 5 in a direction toward the outside of the through hole 7, and the constituent members 5 are displaced outward of the through hole 7 as indicated by broken lines in A, B of fig. 3. At this time, the elastic member 10 expands (generates a restoring force), and the restoring force is applied from the elastic member 10 to the component member 5 according to the displacement (conditions such as the magnitude of the displacement) of the movable component member 8 in the direction toward the outside of the through hole 7. In the case of A, B of fig. 3, the elastic member 10 tightens the support 3 from the outer side 13 of the constituent member 5. When the holding object M is the container 101 and the flange 103 is present in the container 101 as described above, the flange 103 is caught on the upper surface side of the component member 5, and the holding object M is supported by the component member 5 of the holding jig 1 (supported by the supporting portion 3).

When the holding object M is removed from the supporting portion 3, the state in which the holding object M is supported by the component member 5 of the holding jig 1 is released. At this time, the pressing force is released, and the balance between the pressing force and the restoring force (stress) is broken. That is, when the pressing force is released, the stress applying mechanism 9 displaces the constituent member 5 in the direction toward the inside of the through hole 7 based on the action of the stress (restoring force) applied to the constituent member 5.

[1-2 action and Effect ]

According to embodiment 1, the size of the insertion portion 2 is changed in response to displacement of the constituent member 5, and the size of the support portion 3 can be changed. Even with respect to a plurality of types of containers 101 having different sizes as the holding objects M, the containers 101 can be brought into contact with the upper surface of the constituent member 5 by the same holding jig 1, and the containers 101 can be supported by the supporting portion 3.

In addition, according to the holding jig 1 of embodiment 1, the sizes of the insertion portion 2 and the support portion 3 can be varied in accordance with the displacement of the component member 5, and thus, the size and shape of the main body portion 102 of the container 101 can be adapted to the case where the size and shape themselves have variation (rattling).

Next, a modification of embodiment 1 will be described. The modifications described below may be combined with each other as long as they are not contradictory.

[1-3 modification ]

Modification 1

In the holding jig 1 according to embodiment 1, as shown in fig. 4, A, B, C and D, the shape of the component member 5 may be different from the "shape obtained by removing the sector from the sector" shown in fig. 2, a, etc., when the direction from the upper surface toward the lower surface (bottom surface) of the component member 5 is the line of sight direction. This embodiment is referred to as modification 1 of embodiment 1. A, B, C and D in fig. 4 are perspective views showing an example of the component member 5 used in one example of the holding jig 110 of modification 1 of embodiment 1.

In A, B, C of fig. 4, the component member 5 has an inner side surface 12, an outer side surface 13, and a lateral side surface 14, and the inner side surface 12 is formed in a convex arc surface shape or a planar surface shape, respectively.

In fig. 4D, in the component member 5, the lateral side surface 14 is connected to the inner side surface 12, and the inner side surface 12 forms a convexly curved surface.

Modification 2

In the holding jig 1 of embodiment 1, in the example of a in fig. 2, the plurality of constituent members 5 have the same shape and size, but the shape and size of the plurality of constituent members 5 may be different. For example, as shown in fig. 5, in the case where a combination of two constituent members 5 (1 st constituent member 5a and 2 nd constituent member 5 b) is selected from constituent members 5, a plurality of types of constituent members 5 may be used in such a manner that the combination can be selected such that the two constituent members 5 are different in size.

Modification 3

In the holding jig 1 according to modification 2 of embodiment 1, in the example of the arrangement of the constituent members 5 shown in fig. 5, the case where the shape and size of the constituent members 5 arranged at two predetermined places are different from those of the other constituent members 5 is exemplified. In the case where a plurality of types of constituent members 5 are used, the arrangement of the constituent members 5 is not limited to the example shown in modification 2 of embodiment 1. For example, as shown in fig. 6, with respect to the constituent members 5 arranged at the predetermined positions (selected constituent members 5 c), as for the constituent members 5 which are farther from the selected constituent members 5c set as the reference along the arrangement direction a of the constituent members 5, the size of the constituent members 5 becomes smaller, and the size of the constituent members 5 becomes smaller to a predetermined size, in which case the size of the constituent members 5 may become substantially equal further from the constituent members 5 which are smaller to the predetermined size to the direction away from the selected constituent members 5 c. Further, when a line formed by connecting the center of the constituent member 5 and the center of the constituent member 5 adjacent to the constituent member 5 is assumed, the arrangement direction a (parallel direction) indicates the direction in which the line extends.

Modification 4

In the holding jig 1 of embodiment 1, the stress applying mechanism 9 has the elastic members 10, and as shown in A, B of fig. 7, the stress applying mechanism 9 may have a plurality of elastic members 10 so as to apply stress to each of the constituent members 5 independently. This embodiment is referred to as modification 4 of embodiment 1. In the example shown in A, B of fig. 7, the stress applying mechanism 9 has a plurality of elastic members 10, and is configured such that each elastic member 10 applies stress to each component member 5. Fig. 7 is a plan view and a cross-sectional view showing an example of the holding jig 1 according to modification 4 of embodiment 1. The case where stress is applied independently to each component 5 is not limited to the case where stress is applied only to the component 5 (the target component 5) to which stress is directly applied to the elastic member 10, and includes the case where the influence of the stress from the elastic member 10 affects other components 5 through the target component 5.

(stress applying mechanism 9)

In the example of the holding jig 1 shown in A, B of fig. 7, the stress applying mechanism 9 includes a plurality of elastic members 10 and a support member 15.

(support member 15)

The support member 15 is formed with a wall surface 16 on the outside of the constituent element 5. The support member 15 may be disposed above the substrate 6. The support member 15 is the following: is directly or indirectly connected to (or fixed to) one of the two ends of the elastic member 10 separated in the expansion and contraction direction of the elastic member 10, and receives a restoring force accompanying the expansion and contraction of the elastic member 10.

(elastic member 10)

The elastic member 10 is disposed between the constituent member 5 (in particular, the movable constituent member 8) and the wall surface portion 16 of the support member 15. As the elastic member 10, a spring or the like can be used as described in embodiment 1. In the example of A, B in fig. 7, when the movable component 8 is displaced in the direction toward the outside of the through hole 7, a restoring force is generated in the elastic member 10.

(Range restriction Structure 17)

In the holding jig 1 according to modification 4 of embodiment 1, the support member 15 can function as the range limiting structure 17. The range restricting structure 17 represents a structure that restricts the displacement range of the movable component member 8. In the holding jig 1 shown in A, B of fig. 7, the movable component 8 is restricted from being displaced inward in the portion surrounded by the wall surface 16 formed on the support member 15, and from being displaced outward in comparison with the wall surface 16 of the support member 15.

Modification 5

As shown in the holding jig 1 of modification 3 of embodiment 1, when the stress applying mechanism 9 includes the elastic member 10 and the support member 15, the elastic member 10 may be a resilient material 18 such as rubber. This embodiment is referred to as modification 5 of embodiment 1. As shown in example A, B of fig. 8, in holding jig 1 according to modification 5 of embodiment 1, rebound material 18 may be filled between support member 15 and outer side surface 13 of component member 5. Fig. 8 is a plan view and a cross-sectional view showing an example of the holding jig 1 according to modification 5 of embodiment 1. In the example of A, B in fig. 8, when the movable component 8 is displaced in the direction toward the outside of the through hole 7, a restoring force can be generated by applying a force that causes the inner surface side portion of the rebound material 18 to extend in the arrangement direction a of the movable component 8. In addition, a restoring force can be generated by applying a force to compress the rebound material 18 toward the outside of the through hole 7.

Modification 6

In the holding jig 1 of embodiment 1, as illustrated in A, B of fig. 9, the stress applying mechanism 9 may have a relay material 19 between the elastic member 10 and the constituent member 5. This mode is referred to as modification 6 of embodiment 1. Fig. 9 is a plan view and a cross-sectional view showing an example of the holding jig 1 according to modification 6 of embodiment 1. In modification 6 of embodiment 1, the elastic member 10 is the same as that described in embodiment 1, and therefore, description thereof is omitted.

(Relay material 19)

The relay material 19 is not particularly limited as long as it is configured to be able to transmit the restoring force of the elastic member 10 to the movable component 8, but is preferably configured to be able to transmit the restoring force of the elastic member 10 to a combination of the plurality of movable components 8 from the viewpoint of reducing the number of parts of the elastic member 10. For example, in the example of A, B in fig. 9, the relay material 19 is disposed so that the restoring force of one elastic member 10 can be applied to the movable component members 8 adjacent to each other via the relay material 19. The shape of the relay material 19 is formed in a wedge shape, but this is only an example, and may be a circular shape, a rectangular shape, or a polygonal shape.

Modification 7

As shown in A, B of fig. 10, the holding jig 1 of embodiment 1 may be provided with a direction restricting structure 20. This embodiment is referred to as modification 7 of embodiment 1. Fig. 10 is a plan view and a cross-sectional view showing an example of the holding jig 1 according to modification 7 of embodiment 1.

(Direction restriction Structure 20)

The direction restricting structure 20 represents a structure that restricts the displacement direction of the movable component member 8. The holding jig 1 may be provided with a direction restricting structure 20 for at least a part of the plurality of constituent members 5 (the movable constituent members 8 in embodiment 1). In A, B of fig. 10, the direction limiting structure 20 is provided with respect to the four movable constituent members 8.

The direction regulating structure 20 is not particularly limited as long as it can regulate the displacement direction of the movable component member 8, but in the example of A, B of fig. 10, it is constituted by a combination of a boss 21 (columnar body) and a receiving hole 22 that supports the boss 21.

(post 21)

In the example of A, B of fig. 10, the stud 21 is disposed on the substrate 6 and extends upward from the substrate 6. The length of the boss 21 is not particularly limited as long as it extends upward from the upper surface of the constituent member 5.

(receiving hole 22)

The receiving hole 22 is formed in the movable component member 8 in the example of A, B of fig. 10. The displacement of the movable component member 8 substantially coincides with the formation range of the receiving hole 22. For example, in the case where the receiving hole 22 is formed by a long hole (a hole longer in a predetermined direction), and the longitudinal direction of the receiving hole 22 is a direction from the inside to the outside of the through hole 7, the displacement of the movable component member 8 is substantially a direction from the inside to the outside of the through hole 7.

(Range restriction Structure 17)

In addition, in the holding jig 1 according to modification 7 of embodiment 1, the direction limiting structure 20 can also function as the range limiting structure 17. The range limiting structure 17 is a structure for limiting the displacement range of the movable component member 8 as described in modification 4 of embodiment 1. With respect to the boss 21 constituting the direction restriction structure 20, the boss 21 can relatively move inside the formed portion of the receiving hole 22 with respect to the receiving hole 22 with the displacement of the movable component member 8. Since the movement range of the boss 21 relative to the receiving hole 22 is determined, the displacement range of the receiving hole 22 is determined. In A, B of fig. 10, a long hole is formed in the movable component member 8, whereby the displacement range of the movable component member 8 is limited by a range corresponding to the displacement range of the receiving hole 22.

Modification 8

As shown in A, B of fig. 11, the holding jig 1 of embodiment 1 may be provided with a cover plate 23. This embodiment will be referred to as modification 8 of embodiment 1. Fig. 11 is a plan view and a cross-sectional view showing an example of the holding jig 1 according to modification 8 of embodiment 1.

(cover plate 23)

The cover plate 23 covers at least a part of the upper surface side of the constituent member 5. The cover plate 23 is provided with an exposure hole 24. The exposure hole 24 penetrates the cover plate 23 in the thickness direction of the cover plate 23 and exposes the insertion portion 2. The cover plate 23 is provided to the holding jig 1, whereby when the movable component member 8 is displaced, the occurrence of an unintended floating state and tilting state in the movable component member 8 can be suppressed. The floating state of the movable component 8 referred to herein means a state in which the movable component 8 floats upward from the base plate 6. In addition, the inclined state in the movable component member 8 referred to herein means a state in which an inclination occurs in the upper surface of the movable component member 8 due to a floating occurring at a part in the vicinity of the side surface of the movable component member 8.

(layer difference 25)

In the holding jig 1 according to modification 8 of embodiment 1, as shown in fig. 11C, a step 25 may be provided on the constituent member 5. Fig. 11C is a cross-sectional view showing an example of the holding jig 1 in the case where the constituent member 5 is provided with the step 25, and is a diagram for explaining a state of a cross section corresponding to the G-G line longitudinal section of a of fig. 11.

The step 25 may be provided on the upper surface side of at least a part of the plurality of constituent members 5. In the example of fig. 11C, the level difference 25 is provided with respect to the upper surface side of any one of the plurality of constituent members 5. The level difference 25 is preferably provided inside the exposure hole 24 of the cover plate 23 in a plan view of the holding jig 1.

The step 25 is formed so as to cross the upper surface of the constituent member 5 at a predetermined position between the upper end of the inner side surface 12 and the upper end of the outer side surface 13. When the upper surface of the component member 5 is divided into a 1 st portion 26 located closer to the insertion portion 2 (closer to the inner surface 12) than the step 25 and a 2 nd portion 27 located farther from the insertion portion 2 (closer to the outer surface 13) than the step 25, the step 25 is formed such that the 1 st portion 26 is located higher than the 2 nd portion 27 in the vertical direction (the position of the upper surface of the component member 5 is higher toward the insertion portion 2).

In fig. 11C, the lower surface of the cover plate 23 is located below the 1 st portion 26 at a position in the up-down direction.

(Range restriction Structure 17)

In the holding jig 1 shown in fig. 11C, the combination of the level difference 25 and the exposure hole 24 of the cover plate 23 can also function as the range limiting structure 17. As described in modification 4 of embodiment 1, the range limiting structure 17 limits the displacement range of the movable component member 8. In the holding jig 1 shown in fig. 11C, the lower surface of the cover plate 23 is positioned on the lower side than the 1 st portion 26 in the position in the up-down direction. When the movable component 8 is displaced in the outward direction, the position of the step 25 approaches the exposure hole 24 of the cover plate 23, and the displacement in the outward direction by the movable component 8 is restricted at the position where the lower step 25 contacts the exposure hole 24 of the cover plate 23. In fig. 11C, the displacement range of the movable component member 8 is limited to the range of the exposure hole 24 by the combination of the step 25 and the cover plate 23. The specific displacement range of the movable component member 8 depends on the distance between the level difference 25 provided on the movable component member 8 and the exposure hole 24 in the component member 5.

Modification 9

As shown in A, B of fig. 12, the holding jig 1 of embodiment 1 may be provided with a length changing mechanism 28. This mode is referred to as modification 9 of embodiment 1. Fig. 12 is a plan view and a cross-sectional view showing an example of the holding jig 1 according to modification 8 of embodiment 1.

(Length Change mechanism 28)

The length changing mechanism 28 changes the length of the constituent members 5 along the arrangement direction a of the constituent members 5 in a plan view of the constituent members 5. Here, when a line formed by connecting the center of the component member 5 and the center of the component member 5 adjacent to the component member 5 is assumed, the arrangement direction a of the component member 5 indicates the direction in which the line extends.

The length changing mechanism 28 changes the length of the constituent members 5 along the arrangement direction a according to the distance between the constituent members 5 adjacent to the constituent members 5. In the example of A, B in fig. 12, the length changing mechanism 28 has a structure in which an elastic member 10 is provided in a hole portion 30 provided in a member piece 29 described later.

(component sheet 29)

In the example of A, B of fig. 12, at least a part of the constituent member 5 has a plurality of member pieces 29. The component member 5 provided with the length changing mechanism 28 has a plurality of member pieces 29. The member piece 29 represents a portion constituted for the constituent member 5. In the example of A, B of fig. 12, the constituent member 5 has two member pieces 29.

(elastic member 10 provided in the length changing mechanism 28)

In the component member 5 provided with the length changing mechanism 28, the hole portions 30 are formed in the respective member pieces 29 so as to face each other, and the elastic member 10 is provided in the hole portions 30. The elastic member 10 constitutes a length changing mechanism 28. The elastic member 10 is connected to the inside of the hole portion 30. When the component 5 provided with the length changing mechanism 28 is in the inward displacement state, the elastic member 10 is in the contracted state, and as the component 5 is displaced in the outward direction, the restoring force of the elastic member 10 acts to expand the interval of the component pieces 29. Further, by changing the interval between the adjacent member pieces 29, the length of the constituent members 5 along the arrangement direction a of the constituent members 5 can be changed.

In the example of A, B in fig. 12, when the component member 5 is displaced in the direction toward the inside of the through hole 7, the length changing mechanism 28 applies the restoring force of the elastic member 10 to the member piece 29. In addition, the stress application function applies a pressing force to the component member 5 from the holding object M and applies a restoring force from the elastic member 10 when the component member 5 is displaced in a direction toward the outside of the through hole 7 (when the holding object M is passed through the penetration portion 2 and supported by the support portion 3). When the component member 5 is displaced in the direction toward the outside of the through hole 7, the elastic member 10 of the length changing mechanism 28 expands the interval between the adjacent component pieces 29 by the restoring force applied to the component pieces 29. When the holding object M is removed, the component member 5 is displaced in a direction toward the inside of the through hole 7 by the restoring force from the elastic member 10. Then, a restoring force of the elastic member 10 (contraction of the elastic member 10) is applied to the component piece 29.

In the example of A, B in fig. 12, at least a part of the constituent members 5 has a plurality of member pieces 29 and has the length changing mechanism 28, and therefore, when the constituent members 5 are displaced in the direction toward the outside of the through hole 7 (when the holding object M is passed through the insertion portion 2 and supported by the supporting portion 3), the interval between adjacent constituent members 5 can be reduced. This effect can be more effective when the constituent member 5 has three or more member pieces 29 and has the length changing mechanism 28.

(other examples of the number of component pieces 29)

In the example of A, B of fig. 12, at least a part of the constituent member 5 has two member pieces 29, but as shown in A, B of fig. 13, at least a part of the constituent member 5 may have three or more member pieces 29. In A, B of fig. 13, a case is exemplified in which the movable component 8 has three component pieces 29.

[ embodiment 2 ]

[2-1. Structure ]

As shown in A, B of fig. 14, the holding jig 1 of embodiment 2 has a plurality of constituent members 5, and at least one constituent member 5 of the plurality of constituent members 5 is fixed. This embodiment will be referred to as embodiment 2. In addition, the fixed component member 5 is referred to as an immobilized component member 33. The holding jig 1 of embodiment 2 has the same configuration as that of embodiment 1 except that it has a configuration of an immobilized component member 33. In the description of embodiment 2, the same configuration as that of embodiment 1 will be omitted. In the following description of embodiment 2, the case where one component member 5 is the fixed component member 33 will be exemplified and the description will be continued.

(immobilized component 33)

The immobilization component 33 is preferably immobilized at a position corresponding to the inner displacement state. The inner displacement state is the same as that shown in embodiment 1.

(Displacement control of the movable component member 8 by the stress applying mechanism 9)

By the stress applying mechanism 9, the displacement of the movable constituent member 8 (in embodiment 2, the displacement of all constituent members 5 except the immobilized constituent member 33) can be controlled as follows. When the holding object M is passed through the through hole 7, the holding object M also passes through the insertion portion 2. When the dimension of the holding object M (the dimension in a plan view) exceeds the insertion portion 2 in the state of being displaced inward, the holding object M applies a pressing force to the plurality of constituent members 5 in a direction toward the outside of the through-hole 7, and the constituent members 5 are displaced outward of the through-hole 7 as indicated by a broken line in A, B in fig. 15. The displacement of the immobilized component member 33 is restricted, and the magnitude of the displacement of the component member 5 (movable component member 8) disposed at a position close to the immobilized component member 33 is smaller than the magnitude of the displacement of the component member 5 (movable component member 8) disposed at a position far from the immobilized component member 33.

After the holding jig 1 according to embodiment 2 is used to dispose the holding object M, when the holding object M is removed from the supporting portion 3, the state in which the holding object M is supported by the component member 5 of the holding jig 1 is released. At this time, the pressing force from the holding object M to the component member 5 is released, and the balance between the pressing force and the restoring force (stress) is broken. That is, when the pressing force is released, the stress applying mechanism 9 displaces the constituent member 5 in a direction toward the inside of the through hole 7 based on the action of the stress (restoring force) applied to the constituent member 5.

[2-2 action and Effect ]

According to embodiment 2, the same effects as those of embodiment 1 can be obtained. In addition, according to embodiment 2, the position of the portion of the holding object M corresponding to the immobilized component 33 (the relative position to the holding jig 1) can be set to the same position regardless of the difference in the size of the holding object M.

Next, a modification of embodiment 2 will be described. The modification examples described in embodiment 1 may be combined with embodiment 2 as long as they do not contradict each other.

[2-3 modification ]

Modification 1

As shown in A, B of fig. 16, the holding jig 1 of embodiment 2 may be provided with a cover plate 23 and a step 25 as shown in modification 8 of embodiment 1. This mode is referred to as modification 1 of embodiment 2. Fig. 16 is a plan view and a cross-sectional view showing an example of the holding jig 1 according to modification 1 of embodiment 2.

In the holding jig 1 of modification 1 of embodiment 2, the position where the level difference 25 is provided may be made different depending on whether the position of the movable component 5 is located near the fixed component 33 or at a position distant from the fixed component 33. In addition, regarding the size and shape of the exposure hole 24 formed on the cover plate 23, the size and shape of the exposure hole 24 may be determined according to the magnitude of displacement of the movable component 5. In the example of A, B of fig. 16, the shape of the exposure hole 24 is formed in a substantially elliptical shape.

(Direction restriction Structure 20)

The holding jig 1 shown in A, B of fig. 16 is provided with the direction regulating structure 20 shown in modification 7 of embodiment 1. The direction limiting structure 20 has a boss 21 and a receiving hole 22. However, in the holding jig 1 shown in A, B of fig. 16, the mounting portion 32 to which the boss 21 is mounted is formed in the substrate 31, and the boss 21 is fixed to the substrate 6 in a state of being inserted into the mounting portion 32. The mounting portion 32 may be exemplified by a mounting hole and a structure portion having a C-shaped cross section in which a part of the mounting hole is cut away.

(Range restriction Structure 17)

In the holding jig 1 shown in A, B of fig. 16, as shown in modification 7 of embodiment 1, the direction limiting structure 20 can also function as the range limiting structure 17. The range limiting structure 17 is a structure for limiting the displacement range of the movable component member 8 as described in modification 4 of embodiment 1. The range limiting structure 17 constituted by the direction limiting structure 20 shown as A, B in fig. 16 is referred to as a 1 st range limiting structure 17a.

In the holding jig 1 shown in A, B of fig. 16, as in modification 8 of embodiment 1, the combination of the level difference 25 and the exposure hole 24 of the cover plate 23 can also function as the range limiting structure 17. The range limiting structure 17 constituted by the combination of the level difference 25 and the exposure hole 24 of the cover plate 23 as shown in A, B of fig. 16 is referred to as a 2 nd range limiting structure 17b.

In the holding jig 1 shown in A, B of fig. 16, the movement of the constituent member 5 can be controlled more precisely by the 1 st range restriction structure 17a and the 2 nd range restriction structure 17b.

Modification 2

In the holding jig 1 according to embodiment 2, the stress applying mechanism 9 may make the restoring force from the elastic member 10 applied to the component member 5 disposed at a position close to the fixed component member 33 different from the restoring force from the elastic member 10 applied to the component member 5 disposed at a position far from the fixed component member 33 (not shown). This mode is referred to as modification 2 of embodiment 2.

In the concept of the constituent member 5 disposed at a position close to the immobilized constituent member 33, a plurality of constituent members 5 disposed in a predetermined region close to the immobilized constituent member 33 are included in addition to one constituent member 5 at a predetermined position close to the immobilized constituent member 33. In the concept of the constituent member 5 disposed at a position distant from the immobilized constituent member 33, a plurality of constituent members 5 disposed in a predetermined region distant from the immobilized constituent member 33 are included in addition to one constituent member 5 at a predetermined position distant from the immobilized constituent member 33.

Embodiment 3 will be described next. Embodiment 3 is a capping device 41 using the holding jig 1 described in embodiment 1 or embodiment 2.

[ embodiment 2 ] 3 rd embodiment

[2-1 construction of capping device 41 ]

As shown in fig. 17, the capping device 41 of embodiment 3 includes a pressing body 42 and a holding jig 1. The holding jig 1 described in embodiment 1 or embodiment 2 is used. In the case where the holding jig 1 described in embodiment 2 is applied, the holding jig 1 is preferably disposed in the capping device 41 so that the fixed component member 33 is located at the front side or the rear side of the capping device 41. Fig. 17 is a side view showing an example of the capping device 41 according to embodiment 3. In fig. 17, description of the constituent member 5, the substrate 6, and the like is omitted for convenience of explanation.

The capping device 41 includes: a support structure 44 for supporting the pressing body 42 and the holding jig 1; a 1 st support 46 connecting the pressing body 42 to the support structure 44; and a 2 nd support 47 connecting the holding jig 1 with the support structure 44. The support structure 44 is provided with an up-and-down movement mechanism 45 (a movement mechanism for moving the pressing body 42 in the arrow F direction in fig. 17) (not shown) for moving the pressing body 42 up and down. The vertical movement mechanism 45 may be a movement mechanism that moves the position of the 1 st support 46 up and down. The pressing body 42 moves toward the holding jig 1 to a predetermined position (upper position) near the upper side (+f direction side) with respect to the holding jig 1. The lower position and the upper position may be predetermined according to the content of the holding object M or the like.

The pressing body 42 shown in the example of fig. 17 can be located directly above the holding jig 1. The pressing body 42 is preferably provided with a heating mechanism. In this case, the pressing body 42 also functions as a heating body, and the cap device 41 functions as a heat sealing device. The pressing body 42 has a pressing surface 43, and the pressing surface 43 faces the holding jig 1. And the holding object M receives a pressing force between the pressing surface 43 and the holding jig 1. The shape of the pressing surface 43 is not particularly limited. In the example of fig. 17, the pressing surface 43 is formed in a planar shape. However, this is merely an example, and the shape of the pressing body 42 and the shape of the pressing surface 43 are not limited.

In the example of fig. 17, the pressing body 42 moves up and down, but the capping device 41 may move the holding jig 1 up and down, or both the pressing body 42 and the holding jig 1 may move up and down.

(capping function)

The capping device 41 can perform a capping function as follows. Further, the capping function will be described further by taking, as an example, a case where the holding object M is a container 101, the container 101 having a main body 102 and a flange 103 extending in an outward direction from an upper edge of the main body 102. Further, as shown in fig. 18, a case where the container 101 is configured as follows is taken as an example: the body 102 is tapered from the upper end toward the lower end, and the body 102 of the container 101 has an opening 104 formed at the upper end side and a space 106 surrounded by the body 102 and the bottom 105.

The main body 102 of the container 101 is disposed in the holding jig 1. When the body 102 passes through the insertion portion 2 of the holding jig 1, even if the outer peripheral surface 102a of the body 102 of the container 101 contacts the support portion 3 of the holding jig 1, the component member 5 can be displaced in the outer direction in accordance with the size of the outer peripheral surface 102a of the body 102 to expand the size of the support portion 3. When the flange 103 of the container 101 contacts the supporting portion 3 (the flange 103 contacts the upper surface of the component member 5), the container 101 is supported by the holding jig 1.

In the container 101, a lid 111 is disposed on the container 101 so as to cover the opening 104 (and the space 106) of the upper surface of the body 102 and the flange 103. The cover 111 may be a paper cover or a plastic cover. The timing of disposing the cover 111 on the container 101 is not particularly limited. The container 101 may be arranged at the capping device 41 at a timing when the pressing body 42 moves downward. However, the cover 111 is disposed on the container 101 so as to cover the upper opening of the body 102 and the flange 103 at a timing before the holding jig 1 receives the pressing force from the pressing body 42.

In the capping device 41, in a state where the cap is disposed on the container 101 so as to cover the upper opening of the main body 102 and the flange 103, the cap 111 and the container 101 are pressed between the pressing body 42 and the holding jig 1 at the position of the flange 103 of the container 101. At this time, the lid 111 and the container 101 are preferably heated (preferably, the lid 111 and the container 101 are heat-sealed). This causes the lid 111 to engage the container 101.
