Description

  The present invention relates to a cylindrical body positioning tool, and more particularly, a cylindrical body that is provided in a storage box and that positions a cylindrical body that is vertically placed in the storage box in a plane direction perpendicular to the axis. The present invention relates to a body positioning tool.

  As a conventional oil filter, it has a cylindrical housing attached to the engine side and a filter element accommodated in the housing, and an oil inlet and outlet are formed at the shaft end of the housing. It is generally known that a gasket for sealing between the engine side is mounted (see, for example, Patent Document 1). This oil filter is accommodated vertically in a storage box (also referred to as a “return box”) and transported. During the transport, the shaft end of the housing (especially grease is attached). It is required to protect the gasket).

  Therefore, in the transportation using the oil filter storage box, for example, as shown in FIGS. 11 and 12, a partition member 103 provided in the storage box 102 and dividing the storage box 102 into a plurality of spaces is adopted. Has been. The partition member 103 is formed in a lattice shape in which a vertical plate and a horizontal plate are assembled. Then, a dumper plate 104 is laid on the bottom surface of the storage box 102, a vinyl dustproof sheet 105a is laid on the dumper plate 104, a partition material 103 is placed on the dustproof sheet 105a, and each partition wall 103 is partitioned by the partition material 103. The oil filter 113 is put into the space, and the dust filter 105b is put on the upper side of the partitioning material 103 together with the oil filter 113 which is fully loaded, and is transported to the destination in that state. The oil filter 113 housed vertically in the housing box 102 is positioned by the partition member 103 in the plane direction perpendicular to the axis. On the other hand, at the transportation destination, the dustproof sheet 105b is uncovered, the oil filter 113 is taken out from the storage box 102, and assembly work to the engine side is performed. In addition, since the said dust-proof sheet | seat 105a, 105b adheres grease, a new thing is used for every delivery.

  However, since the conventional partition material 103 is formed in a lattice shape formed by assembling the vertical plate and the horizontal plate, in order to protect the shaft end of the housing of the oil filter 113 from dust, It is necessary to lay the dustproof sheet 105a and cover the dustproof sheet 105b on the upper side of the partition member 103. This increases the material cost of the vast dustproof sheets 105a and 105b and increases the number of work steps. Moreover, when the partition material 103 deform | transforms by long-term use etc., the injection | operating workability | operativity of the oil filter 113 with respect to each space of the partition material 103 deteriorates. In particular, with automatic loading by a robot, the oil filter 113 cannot be loaded into each space of the partition member 103, and equipment troubles may occur. Further, since the height of the partition member 103 is substantially the same as the axial length of the oil filter 113, when the oil filter 113 is taken out from the storage box 102, the operator's fingertip contacts the partition member 103. There is a sense of resistance, and the oil filter 113 removal workability is poor. The above-mentioned problem occurs similarly even in a cylindrical body other than the housing of the oil filter 113 (for example, an air flow meter or an air cleaner vent pipe).

The axial height h1 of the positioning body 3 is set to a value smaller than the axial height h2 of the housing 14 (specifically, about 70% of the axial height h2 of the housing). The axial height h2 of the cylindrical body 14 is the height of the cylindrical body 14 including the caps 21 and 22 attached to the shaft end portions.

  The insertion hole 5 is formed so that the housing 14 can be inserted in the axial direction so as to position the housing 14 in the planar direction. The housing 14 inserted through the insertion hole 5 is positioned in the planar direction by the inner peripheral surface 5 a of the insertion hole 5 of the positioning body 3 surrounding the outer peripheral surface of the housing 14. The insertion hole 5 is formed so that the shaft end portion of the housing 14 can be inserted in a state where the caps 21 and 22 are attached to the shaft end portion on the bottom surface side of the housing 14. Specifically, the diameter d1 of the insertion hole 5 is slightly larger than the maximum outer diameter d2 (see FIG. 6) of the housing 14 and slightly larger than the maximum outer diameter d3 of the caps 21 and 22 attached to the shaft ends of the housing 14. It is considered to be a small value.

  The positioning body 3 is provided with a cap detachment portion 7 that engages with the caps 21 and 22 to detach the caps 21 and 22 from the shaft end portions of the housing 14 when the housing 14 inserted through the insertion hole 5 is taken out. It has been. The cap detachment portion 7 includes a step-shaped diameter-enlarged portion 8 whose diameter is increased outside (that is, the centrifugal side) from the inner peripheral surface 5 a of the insertion hole 5 of the positioning body 3. The enlarged diameter portion 8 is disposed adjacent to the lower end side close to the bottom surface 2 a of the storage box 2 in the axial direction of the insertion hole 5.

However, normally only one of the oil filter 13 including the cap 21 and the oil filter 13 including the cap 22 is stored in the storage box 2.

  At the transportation source, the base plate 4 is placed on the bottom surface 2a of the storage box 2, and the positioning tool 1 is provided in the storage box 2 (see FIG. 4A). Then, the housing 14 is inserted in the axial direction from the shaft end portion on the bottom surface side where the caps 21 and 22 are attached to the insertion hole 5 of the positioning body 3 (see FIG. 4B). During the insertion into the insertion hole 5, the caps 21 and 22 are pressed inward by the inner peripheral surface 5 a of the insertion hole 5 of the positioning main body 3 and elastically deformed (ie, reduced in diameter). Thereafter, when the insertion of the housing 14 further proceeds, the caps 21 and 22 enter the enlarged diameter portion 8 and the through hole 11 and return to the original shape (see FIG. 4C). At this time, the housing 14 is housed in the housing box 2 in a state where the shaft end on the bottom surface side is dust-proofed by the caps 21 and 22 and is positioned with play in the planar direction. Further, a part of the housing 14 projects upward from the upper end of the positioning body 3. Thereafter, the above-described operation is repeated, and the desired number of oil fills 13 are transported to the transport destination in a state of being stored in the storage box 2.

  At the transportation destination, the housing 14 is taken out from the insertion hole 5 by grasping a portion protruding above the positioning body 3. At the time of removal, the cap detachment portion 7 (specifically, the upper surface of the enlarged diameter portion 8) and the caps 21 and 22 are engaged (see FIG. 5A), so that the bottom surface side of the housing 14 is engaged. The caps 21 and 22 are detached from the shaft end portions and remain in the enlarged diameter portion 8 and the through hole 11 (see FIG. 5B). Thereafter, after all the oil filters 13 are taken out, the storage box 2 is returned to the transportation source. In addition, the assembly | attachment operation | work etc. to the engine side of the oil filter 13 etc. are performed in a transport destination.

  At the transportation source, by lifting the positioning tool 1 from the inside of the storage box 2 returned from the transport destination, the detached caps 21 and 22 are left in the storage box 2 through the through holes 11 (FIG. 5C). reference). The caps 21 and 22 left in the storage box 2 are collected for reuse after disposal or cleaning. Since the container 2 and the positioning tool 1 from which the caps 21 and 22 have been collected are free from grease, the positioning tool 1 is set in the container 2 and reused without being cleaned.

(3) Effects of Embodiment The housing positioning tool 1 of this embodiment includes the positioning body 3 in which the insertion hole 5 through which the housing 14 can be inserted in the axial direction is formed so as to position the housing 14 in the plane direction. The insertion hole 5 is formed so that the shaft end portion of the housing 14 can be inserted in a state where the caps 21 and 22 are attached to the shaft end portion on the bottom surface side of the housing 14. The positioning body 3 has a cap detachment portion 7 that engages with the caps 21 and 22 to detach the caps 21 and 22 from the shaft end portions of the housing 14 when the housing 14 inserted through the insertion hole 5 is taken out.

Positioning can be performed easily and inexpensively. Further, when the housing 14 is taken out from the insertion hole 5 of the positioning body 3, the caps 21 and 22 are detached from the shaft end portions of the housing 14 by engaging the cap removing part 7 and the caps 21 and 22. The handling property of the taken out housing 14 is excellent.

  Further, in this embodiment, a base plate 4 is provided which is placed on the bottom surface 2a of the storage box 2 and on which the plurality of positioning bodies 3 are arranged in parallel. Thereby, the some positioning main body 3 and the baseplate 4 can be integrated, and the handleability of the positioning tool 1 is improved. Further, the housing 14 can be easily and accurately inserted into the insertion holes 5 of the plurality of positioning bodies 3 on the base plate 4. Therefore, even when automatic insertion of the oil filter 13 by a robot is employed, it can be input with high accuracy.

  Further, in the present embodiment, the base plate 4 is formed with through holes 11 wider than the outer peripheries of the caps 21 and 22 at positions corresponding to the insertion holes 5 of the plurality of positioning bodies 3.
