Description

  The present invention relates to a storage basket for cleaning parts, particularly suitable for cleaning rotationally symmetric circular parts such as optical lenses.

  Conventionally, in a manufacturing process of an optical glass lens, since a glass material is ground and polished, and then cleaned, a cleaning storage basket, for example, the cleaning storage basket disclosed in Patent Document 1 is shown in FIGS. Packed in a storage basket for cleaning.

FIG. 10 is a part of a top view of a conventional cleaning storage basket, and FIG. 11 is a side view thereof. The conventional cleaning storage basket includes three movable holding frames 113 that hold the lens L between two frame plates 111 (only one of which is shown). The holding frame 113 is fixed to a metal round bar 114 with a resin plate 115 having grooves (unevenness) 115a that abuts and holds the outer peripheral edge of the lens L at predetermined intervals along the long side. Each holding frame 113 has round bars 114 at both ends inserted through the horizontal slits 111a and 111b and the vertical slit 111c formed in the frame plate 111 so as to be movable, and formed at the leading end protruding from the slits 111a to 111c. A nut 117 is screwed into the male thread portion. Thus, each holding frame 113 is positioned on the resin plate 115 such that the unevenness 115a faces the center of the lens L, and is fixed to the frame plate 111 by tightening the nut 117. Each holding frame 113 can freely move in the slits 111a to 111c along the slits 111a to 111c by loosening the nut 117, and thus can hold lenses having various external dimensions within the moving range.
Utility Model Registration No. 2549372

  However, since the positions of the three holding frames 113 can be adjusted, the degree of freedom of adjustment is high. On the other hand, there are many adjustment points by the nut 117, and each resin plate 115 rotates simultaneously with the position adjustment of the holding frame 113. Therefore, it is difficult to adjust when housing lenses having different external shapes. For this reason, at the end of the processing line, when the frame is put into the cleaning storage basket by the robot, there is a problem that the lens L falls off because the orientation of the holding frame 113 (resin plate 115) has shifted for some reason. Further, it takes time to adjust the position and orientation of the holding frame 113, and means such as stopping the processing line is necessary, which causes a reduction in manufacturing efficiency.

  Further, as one means for solving this problem, there is a cleaning storage basket in which the size of the holder portion is fixed as disclosed in Patent Document 1. However, in such a conventional structure, if there are lenses with different outer diameters, a dedicated cleaning storage basket is required for each lens outer diameter, and the cost for preparing a large amount of cleaning storage basket and the storage for cleaning them are required. There was a problem that a space for storing the basket was required.

  The present invention has been made in view of the problem of such a conventional lens cleaning storage basket, and provides a component storage basket that can be easily adapted to lenses of various diameters and can be easily stored. The purpose is to do.

  The present invention for solving such a problem is a basket for holding a plurality of circular parts in a state of being separated from each other, and a pair of frame plates arranged in parallel to each other, a hole, a horizontal long hole in the horizontal direction, and the long hole A holding plate having an abutting portion that forms an inclined elongated hole that is inclined at a predetermined angle with respect to the horizontal elongated hole and abuts and supports the peripheral edge of each of the circular components below the horizontal elongated hole. Arranged in a direction to support the peripheral part of the circular part from three directions, the shaft part protruding in parallel with the longitudinal direction from the both end parts of each holding plate is a hole, a long hole and one inclined length of the corresponding frame plate A long hole inserted through the hole and disposed outside the plate frame, into which the shaft portion penetrating the horizontal oblong hole is inserted, and a hole into which the shaft portion penetrating the inclined oblong hole is inserted, and A linking member that links and moves each shaft portion along the horizontal slot and the inclined slot. Characterized in that comprises a.

  The inclined long hole is preferably formed so as to form approximately 45 degrees with respect to the horizontal long hole. In this case, each shaft portion inserted into the hole, the horizontal oblong hole, and the inclined oblong hole becomes a vertex of a right isosceles triangle whose apex is the shaft portion inserted into the inclined oblong hole, and the linkage member is Each shaft portion is linked and moved so as to maintain the similar shape of the right isosceles triangle. According to this configuration, the circular part can be supported in the diametrical direction and the lower end.

  The linkage member is a plate-like member, and the elongated hole extends toward the hole.

  More practically, the shaft portion that penetrates the inclined slit and is inserted into the hole of the linkage member is fixed to be movable along the inclined slit and integrally movable to the linkage member. The shaft portion inserted into the horizontal slit and the hole of the linkage member has a fixed state in which the shaft portion is fixed to the frame plate and the linkage member, and the horizontal slot and the slot. A fixing member that is restrained and moves in a released state that is movable along the horizontal elongated hole while being relatively moved with respect to the elongated hole of the linkage member is mounted.

  In the embodiment of the holding plate, a rectangular plate-like member extending between the frame plates, and a V-shaped groove is formed as the unevenness along one longitudinal edge of the plate-like member. The shaft portion is fixed to the other longitudinal edge portion.

  According to the present invention, even if the size of the component to be stored changes, the two movable holding frames move in association with the linking member, so that there are few members to be adjusted and the adjustment operation becomes very simple.

  Embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a perspective view of a basket according to an embodiment of the present invention, FIG. 2 is a perspective view of a guide plate used in the basket, FIG. 3 is a side view of the basket, and FIG. 4 is a partially transparent view thereof. FIG. 5 is a side view showing a frame plate of the basket.

  The lens cleaning storage basket of the present invention includes two frame plates 11 held at predetermined intervals and three lens holding frames (components) that hold a plurality of lenses L as circular components between the two frame plates 11. Holding frame) 21, 23, 25. Three sets of lens holding frames 21, 23 and 25 are provided at predetermined intervals in the front-rear direction of the frame plate 11. Further, the four corners of each frame plate 11 are fixed by a fixing rod 51 and a nut 52, respectively. The frame plate 11 is made of stainless steel.

  Each frame plate 11 is formed with a fixing hole 12 and slits (long holes) 13, 14 and 15 for holding the lens holding frames 21, 23 and 25 (see FIG. 5). A fixing hole 12 serving as a reference is formed in the vicinity of the upper side of the frame plate 11, a horizontal slit (horizontal long hole) 13 extending in the horizontal direction is formed at a predetermined distance from the fixing hole 12 in the horizontal direction, and the horizontal slit 13 is further formed. A lower inclined slit (inclined hole) 14 that is inclined approximately 45 degrees with respect to the horizontal direction and becomes higher in the direction of the fixing hole 12 is formed below the lower inclined slit 14. Further, an upper inclined slit 15 is formed between the lower inclined slit 14 and the horizontal slit 13 in parallel with the lower inclined slit 14. The lower inclined slit 14 is formed so that the fixing hole 12 is positioned on the extension.

  Each lens holding frame 21, 23, 25 is positioned between shaft parts 21 a, 23 a, 25 a protruding from both frame plates 11 and both frame plates 11, and one edge in the longitudinal direction is the shaft parts 21 a, 23 a. , 25a, and plate-like frame portions 21b, 23b having a number of V-grooves 21c, 23c, 25c for supporting the lenses formed at predetermined intervals as the concavo-convex portions for holding the lens L on the other longitudinal edge. 25b. Both V-grooves 21c, 23c, and 25c have a structure that holds the lens L by abutting the peripheral surfaces of the lens L.

  The shaft portions 21a, 23a, 25a of the lens holding frames 21, 23, 25 are made of, for example, stainless steel, and the plate-like frame portions 21b, 23b, 25b are made of, for example, a fluororesin. Thus, the shaft portions 21a, 23a, 25a are molded at the longitudinal edges on the opposite side to the V grooves 21c, 23c, 25c formed in the plate-like frame portions 21b, 23b, 25b made of fluororesin. Yes.

  Both ends of the shaft portion 21a of the first lens holding frame 21 pass through the fixing hole 12 of the frame plate 11, both ends of the shaft portion 23a of the second lens holding frame 23 pass through the horizontal slit 13, Both end portions of the shaft portion 25 a of the three-lens holding frame 25 pass through the lower inclined slit 14.

  A small-diameter male screw portion 21a1 is formed at both ends of the shaft portion 21a, and the male screw portion 21a1 projects through the fixing hole 12. The diameter of the shaft portion 21 a is set larger than the inner diameter of the fixing hole 12 so as not to fit into the fixing hole 12. A nut 22 is screwed into a male screw portion 21 a 1 that protrudes through the fixing hole 12, and the frame plate 11 is clamped by the end surface of the shaft portion 21 a and the nut 22, whereby the first lens holding frame 21 is attached to the frame plate 11. It is fixed against. In fixing, the plate-like frame portion 21 b is positioned so as to be parallel to the horizontal slit 13.

  Small-diameter male screw portions 23a1 and 25a1 are formed at both ends of the shaft portions 23a and 25a of the second and third lens holding frames 23 and 25, and the male screw portions 23a1 and 25a1 correspond to the corresponding horizontal of the frame plate 11. The slit 13 and the lower inclined slit 14 are inserted. The widths of the horizontal and lower inclined slits 13 and 14 are formed so that the male screw portions 23a1 and 25a1 can be inserted, but the shaft portions 23a and 25a cannot be inserted.

  A slit (long hole) 32 and a hole 34 of a guide plate (auxiliary plate) 31 are fitted into the male screw portions 23 a 1 and 25 a 1 protruding from the slits 13 and 14 of the frame plate 11. The slit 32 is a long hole extending in the direction of the hole 34 along the longitudinal direction of the guide plate 31.

  A nut 24 constituting a fixing member is screwed to the male screw portion 23a1 protruding from the slit 32 of the guide plate 31. When the nut 24 is rotated in the fastening direction, the guide plate 31 and the frame plate 11 are clamped by the boundary end surface of the shaft portion 23 a and the male screw portion 23 a 1 and the nut 24, and the second lens holding frame 23 is held against the frame plate 11. Can be fixed. When the nut 24 is rotated in the loosening direction, the nut 24 moves away from the boundary end surface of the shaft portion 23a and the male screw portion 23a1, and the guide plate 31 and the frame plate 11 can freely move relative to each other. The male screw portion 23a1 13 can be freely moved along.

  A nut 26 constituting a fixing member is screwed into the male screw portion 25a1 protruding from the hole 34 of the guide plate 31. In the present embodiment, the third lens holding frame 25 has a structure that can move relative to the frame plate 11 and can move integrally while being fixed to the guide plate 31.

  The guide plate 31 is further provided with a fixing hole 33 between the slit 32 and the hole 34 (FIG. 2). Then, the bolt 41 inserted from the upper inclined slit 15 of the frame plate 11 passes through the fixing hole 33, and the nut 42 constituting the fixing member is screwed to the end protruding from the fixing hole 33. . Therefore, when the nut 42 is rotated in the fastening direction, the guide plate 31 and the frame plate 11 are pinched and the guide plate 31 is fixed to the frame plate 11, and when the nut 42 is rotated in the loosening direction, the released state is obtained. Thus, the guide plate 31 becomes movable with respect to the frame plate 11. When the guide plate 31 is fixed with respect to the frame plate 11, the second and third lens holding frames 23 and 25 also cannot move along the horizontal slit 13 and the lower inclined slit 14. The guide plate 31, the nuts 24, 26, and 42 and the bolt 41 are made of, for example, stainless steel.

  FIG. 3 shows the setting when all lenses L having the same diameter are held. FIG. 4 shows three types of lenses LS, LM, and LL, which are a small-diameter lens LS, a medium-diameter lens LM, and a large-diameter lens LL. This shows the setting for holding. In FIG. 3, the small-diameter lens LS is shown in a state where the guide plate 31 is seen through (excluded).

  A structure in which the third lens holding frame 25 is fixed to the guide plate 31 integrally and can be freely moved along the lower inclined slit 14 of the frame plate 11 will be described with reference to FIG. A cylindrical spacer 27 that is slightly thicker than the thickness of the frame plate 11 is fitted into a small-diameter male screw portion 25a1 formed at the end of the shaft portion 25a. The outer diameter of the spacer 27 is formed so as to be insertable into the lower inclined slit 14 and smaller than the diameter of the shaft portion 25a. On the other hand, the hole 34 of the guide plate 31 is formed to have a smaller diameter than the outer diameter of the spacer 27 so as not to fit into the spacer 27. Therefore, when the nut 26 is rotated in the fastening direction, the spacer 27 is clamped by the end face of the shaft portion 25a and the guide plate 31, and the shaft portion 25a is fixed to the guide plate 31 and can be moved integrally. Become. On the other hand, since a slight gap is secured between the frame plate 11 and the lower inclined slit 14, the frame plate 11 and the lower inclined slit 14 are guided so as to be movable.

  According to this embodiment, the third lens holding frame 25 is adjusted so that the plate-like frame portion plate-like frame portion 25b faces the vertical (vertical) direction, and is fastened and fixed to the guide plate 31 by the nut 26. After that, the vertical direction is maintained and the guide plate 31 is moved integrally with the lower inclined slit 14 so that it is not necessary to loosen the nut 26 when adjusting according to the lens diameter.

  In another embodiment, the hole 34 of the guide plate 31 is a slit parallel to the lower inclined slit 14 (not shown). If the slit is used, position adjustment with respect to the guide plate 31 and relative position adjustment with respect to the first and second lens holding frames 21 and 23 are possible.

  Next, an embodiment of a structure for guiding the guide plate 31 so as to be movable in parallel along the upper and lower inclined slits 15 and 14 will be described with reference to FIGS. In this embodiment, a T-groove nut 43 is used, and FIG. 8 is a front view of the T-groove nut 43 cut vertically in the upper half of the axis. 9A is a side view of the T-groove nut 43, and FIG. 9B is a front view of the T-groove nut 43. FIG. The T-groove nut 43 has a rectangular shape when viewed from the axial direction, has a convex shape when viewed from the short side of the rectangular shape, and has a guide surface 44 in which the longitudinal directions of the convex protrusions are parallel to each other.

  The T-groove nut 43 is screwed into the bolt 41 (its male thread portion 41 a) and then inserted into the fixing hole 33 of the guide plate 31 from the upper inclined slit 15 side of the frame plate 11. The guide surface 44 is formed at a height that does not protrude from the fixing hole 33 of the guide plate 31. The nut 42 is screwed into the male thread portion 41 a of the bolt 41 protruding from the T-groove nut 43 through the fixing hole 33.

  The T-groove nut 43 has a parallel guide surface 44 fitted into the upper inclined slit 15 and the fixing hole 33 and is in contact with the inner surface of the upper inclined slit 15 and the inner surface of the fixing hole 33, so that the nut 42 is relaxed. Even in this state, the T-groove nut 43 is constrained by the upper inclined slit 15 and the fixing hole 33 and does not rotate, and can freely move straightly in sliding contact with these inner surfaces. That is, the guide plate 31 is prevented from rotating with respect to the upper inclined slit 15 and is guided along the upper inclined slit 15 so as to be movable in parallel.

  When the nut 42 is further rotated in the fastening direction, the guide plate 31 and the frame plate 11 are pressed against each other by the T-groove nut 43, so that the guide plate 31 is fixed to the frame plate 11 so that it cannot move and rotate. .

  According to the above configuration, when the nuts 24 and 26 are rotated in the fastening direction, the guide plate 31 is pressed against the frame plate 11 and fixed so as not to move. When the nuts 24 and 26 are rotated in the loosening direction, the guide plate 31 is movable with respect to the frame plate 11, and the second and third lens holding frames 23 and 25 are also along the horizontal slit 13 and the lower inclined slit 14. It becomes movable. Therefore, when one of the second and third lens holding frames 23 and 25 is moved along the horizontal slit 13 or along the lower inclined slit 14, the other third and second lens holding frames are restrained by the guide plate 31. 25 and 23 also move together in the contact / separation direction along the lower inclined slit 14 or the horizontal slit 13. Even if the guide plate 31 is moved, the second and third lens holding frames 23 and 25 are similarly linked in the contact / separation direction.

  The V grooves 21c, 23c, and 25c of the first, second, and third lens holding frames 21, 23, and 25 are the first, second, and third lens holding frames 21, 23, and 25, the frame plate 11, and the guide plate 31, respectively. In the mounted state, a line connecting the V-grooves 21c and 23c is used as a base, and a substantially right-angled isosceles triangle is formed with the V-groove 25c as a vertex. That is, the V grooves 21c, 23c, and 25c of the first, second, and third lens holding frames 21, 23, and 25 are formed so as to hold the lens L at a total of three points, the lowest point and two points that sandwich the diameter. Has been. Thus, the horizontal slit 13, the lower inclined slit 14, and the guide are arranged so that the second and third lens holding frames 23, 25 are linked and moved in the direction of enlargement and reduction while maintaining a similar right-angled isosceles triangle. A plate 31 is formed. That is, the first and second lens holding frames 21 and 23 support the horizontal line position passing through the center of the lens L regardless of the diameter of the lens L, and the third lens holding frame 25 is the lowermost position of the lens L ( Supports the position on the vertical line passing through the center.

"Adjustment operation"
The adjustment operation and movement of each member when corresponding to lenses L of different diameters will be described with reference to FIG. In FIG. 6, when the guide plate 31 is slid in the upper left direction, the actual movement direction is indicated by a thick arrow, and the relative movement direction is indicated by a white arrow.

First, the nuts 24 and 26 are rotated in the loosening direction so that the guide plates 31 on both sides can be moved.
Next, the guide plates 31 on both sides are moved to the upper left along the inclined slits 14 and 15 to adjust the position. At this time, the target lens L or a dummy having the same shape may be placed on the V grooves 21c, 23c, and 25c for adjustment.
When the position of the guide plate 31 is determined, the direction of the second lens holding frame 23 is determined, and then the nut 24 is rotated in the fastening direction, and the nut 26 is further rotated in the fastening direction and fixed. The order in which the nuts 24 and 26 are fastened is not limited.

  The adjustment is completed by the above operation. Thus, according to the embodiment of the present invention, of the three lens holding frames 21, 23, 25, the first lens holding frame 21 is fixed once and no adjustment is required, and the third lens holding frame 25 is once set. If it is adjusted independently, it moves in conjunction with the guide plate 31 thereafter, so there is no need to adjust it alone. As described above, according to the present embodiment, the adjustment operation is substantially simple if the second lens holding frame 23 is adjusted. Therefore, the adjustment operation is very simple.

  In the illustrated embodiment, the second lens holding frame 23 is configured to rotate about the shaft portion 23a when the nut 24 is loosened when the lens diameter is changed. However, the shaft portion 23a that fits the horizontal slit 13 is provided in advance. If the plate-shaped frame portion 23b is formed to be rectangular and parallel to the horizontal slit 13, it is not necessary to adjust the inclination of the plate-shaped frame portion 23b.

  In the present embodiment, the bolt and nut structure is used as a member for fixing and releasing the first, second, and third lens holding frames 21, 23, and 25 to the frame plate 11 and the guide plate 31. It is not limited.
