  The drawing operation on the outer peripheral surface of the corrugated tube is performed, for example, by using a ruler member having an arcuate surface along the outer peripheral surface of the corrugated tube and moving the pen tip portion of the marker pen in contact with the side surface. It is possible.

  However, according to the drawing method described above, there is a possibility that the ink of the marker pen adheres to a portion other than the drawing target portion of the corrugated tube. For example, ink adheres to the side surface of the ruler member with which the pen tip portion of the marker pen is in contact, and the adhering ink enters between the ruler member and the corrugated tube and adheres to portions other than the drawing target location. There is a fear. For this reason, a reworking operation for the corrugated tube and a cleaning (ink removal) operation for the ruler member are required, which may reduce the working efficiency.

  Therefore, an object of the present invention is to suppress ink adhesion to a portion other than the drawn line target portion in the corrugated tube.

<1. About Corrugated Tube>
For convenience of explanation, first, the corrugated tube 100 to be drawn is described (see FIG. 1).

  The corrugated tube 100 is a member formed into a long tubular shape (here, a long circular tubular shape) with a resin or the like. More specifically, the corrugated tube 100 includes a peak portion 102 formed in a convex shape along the circumferential direction and a trough portion 104 formed in a concave shape along the same circumferential direction in a longitudinal direction (center). (Along the axial direction).

  The corrugated tube 100 may be attached as a protective member to the wire harness WH in a wire harness manufacturing process of an automobile. When the wire harness WH is laid on the vehicle, a fixing member 110 for fixing the corrugated tube 100 attached to the wire harness WH to a predetermined position of the vehicle is attached. For example, when the same or the same type of corrugated tubes 100 are arranged in parallel in the vehicle, a plurality of corrugated tubes 100 are sandwiched and fixed by a pair of fixing members in which arc-shaped portions are integrally formed in parallel. Sometimes. The attachment position of the fixing member 110 with respect to the corrugated tube 100 is indicated by marking the outer peripheral surface of the corrugated tube 100 in the wire harness manufacturing process.

  Here, an example in which lines are drawn along the circumferential direction with respect to the outer peripheral surfaces of the mountain portions 102 (drawing target positions) located on both sides of the fixing member 110 attached to the corrugated tube 100 will be described. That is, here, the two peak portions 102 of the corrugated tube 100 are drawn. The drawn line range for the mountain portion 102 may be set to a range that can be easily recognized by the laying work of the wire harness WH (for example, a range of 120 degrees or more around the central axis of the corrugated tube 100). In FIG. 1, a drawn part 108 drawn with respect to the mountain part 102 which is a drawn part target part is indicated by a two-dot chain line.

<2. Configuration of corrugated tube marking device>
Next, the configuration of the corrugated tube marking device 10 will be described (see FIGS. 2 to 5).

  In the corrugated tube marking apparatus 10, a marker pen 120 indicated by a two-dot chain line in FIG. 2 is used to draw a line on the outer peripheral surface of the corrugated tube 100. In this marker pen 120, liquid ink is supplied to a pen tip portion 124 (for example, felt) disposed at the tip portion 122, and ink is applied to a portion where the pen tip portion 124 into which the ink has permeated comes into contact. It is a common marker pen configured to attach. Here, an example in which the tip end portion 122 of the marker pen 120 is substantially circular in cross-section is described.

  The marking device 10 of the corrugated tube includes a guided member 20, and a main body member 30 having a support portion 40, a guide portion 60, and an ink avoiding groove portion 70.

  The guided member 20 can be attached to the tip end portion 122 of the marker pen 120, and the tip end portion of the pen tip portion 124 of the marker pen 120 protrudes in the attached state and is formed in a non-contact manner with respect to the pen tip portion 124. (See FIG. 2). Here, the non-contact with the pen tip portion 124 preferably means that the guided member 20 and the pen tip portion 124 have a gap between them so that the ink supplied from the pen tip portion 124 is not retained. It is good that it is in a state.

  More specifically, the guided member 20 can be fitted with the distal end portion 122 of the marker pen 120 from the proximal end side (upper side in FIG. 2), and the distal end of the pen tip portion 124 from the distal end side (lower side in FIG. 2). It is formed in a cylindrical shape (here, substantially cylindrical) having a hole 20a that can project the side portion. The hole 20a may be formed according to the shape of the tip 122 of the marker pen 120 used for drawing. As the shape of the hole 20a, for example, a shape that can be brought into surface contact or line contact along the circumferential direction with respect to the tip portion 122 of the marker pen 120 or a shape that can be contacted at a plurality of locations in the circumferential direction can be adopted. . Here, the guided member 20 is configured to be fitted to the distal end portion 122 of the marker pen 120 when the inner peripheral surface of the hole portion 20a is in surface contact along the circumferential direction.

  In addition, the guided member 20 is configured so that the base end portion is in contact with the step at the boundary between the distal end portion 122 and the base end side portion of the marker pen 120 in the attached state. With this configuration, the guided member 20 is in the central axis direction (vertical direction in FIG. 2) with respect to the marker pen 120 (at a position where the tip side portion of the pen tip portion 124 protrudes from the tip of the guided member 20). Positioned. However, the configuration for positioning the guided member 20 in the central axis direction with respect to the marker pen 120 is not limited to the above, and may be determined according to the shape of the marker pen 120. For example, in the case where a step is formed at the distal end portion 122 of the marker pen 120, the guided member 20 may be formed such that a part of the hole 20a can be brought into contact with the step.

  The guided member 20 has a peripheral wall portion 24 formed so as to surround the pen tip portion 124 around the central axis in the attached state with respect to the marker pen 120. More specifically, the peripheral wall portion 24 is disposed so as to surround the proximal end portion of the pen tip portion 124 around the axis in a non-contact manner in a state where the guided member 20 is attached to the marker pen 120. Yes. More preferably, the peripheral wall portion 24 may be formed so as to leave a gap with which the ink is not retained with respect to the pen tip portion 124. Here, the peripheral wall portion 24 is a part (tip portion) of the tip side portion of the guided member 20, and an inner peripheral surface thereof forms a part of the hole portion 20a.

  The guided member 20 has a guided surface 22 that is an outer peripheral surface of a tip side portion formed in a substantially cylindrical shape. Here, the distal end portion of the guided member 20 is formed with a substantially constant outer diameter in the central axis direction. The guided member 20 is guided by contacting two pairs of guide surfaces 62 of the guide portion 60 described later at two locations facing each other across the central axis of the guided surface 22. In other words, the guided member 20 can come into contact with the guide surface 62 at each of the guided surfaces 22 facing each other across the central axis by rotation around the central axis.

  But the to-be-guided member 20 is not limited to the said substantially cylindrical shape, For example, the outer peripheral part may be formed in the cylinder shape which is a cross sectional view polygon. In addition, when the outer peripheral shape of the front end side portion of the guided member 20 is a polygon in a sectional view, the guided surface 22 has a pair of parallel surfaces facing each other across the central axis of the guided member 20. Good. That is, the guided member 20 only needs to have the guided surface 22 along the central axis direction in the attached state with respect to the marker pen 120. More specifically, the guided surface 22 only needs to be formed so as to face each other across the central axis at a substantially constant distance in the central axis direction of the guided member 20.

  The main body member 30 has a base portion 32 and a lid portion 34 formed of resin or the like, and the lid portion 34 is connected to the base portion 32 via a hinge 33 so as to be opened and closed (FIGS. 3 and 3). 4). But the main body member 30 is not restricted to the said structure, A various other structure is employable. For example, the main body member 30 is a separate structure in which the base 32 and the lid 34 are not connected to each other, and the base 32 and the lid 34 are disposed so as to be able to move toward and away (open and close) by a cylinder or the like. A configuration or a configuration in which the base portion 32 and the lid portion 34 are connected so as to be openable and closable and urged in a closing direction by an urging member such as a spring can be employed.

  The base portion 32 and the lid portion 34 are respectively formed with concave portions 32a and 34a having a support portion 40 and an ink avoiding groove portion 70, which will be described later, at positions facing each other in the closed state. More specifically, the recesses 34 a and 32 a are configured to have an internal space in which the corrugated tube 100 can be disposed along the opening / closing axis direction of the hinge 33 with the base portion 32 and the lid portion 34 closed. Further, in the open state of the base portion 32 and the lid portion 34, the corrugated tube 100 can be disposed with respect to the concave portion 32a or the concave portion 34a.

  The support portion 40 is configured to be able to support the corrugated tube 100 at a fixed position in the central axis direction. The support portion 40 is formed in a concavo-convex shape corresponding to the concavo-convex shape of the peak portion 102 and the valley portion 104 of the corrugated tube 100. That is, the support portion 40 restricts the corrugated tube 100 from moving in the longitudinal direction of the corrugated tube 100 in a state where the peak portion 102 is disposed inside the concave portion and the convex portion protrudes into the valley portion 104. It is comprised so that it can support. Here, the support portion 40 is formed in an arc shape along the outer peripheral surface of the corrugated tube 100, and is configured to restrict movement over the entire periphery of the corrugated tube 100.

  Moreover, the support part 40 is partially formed in the extension direction (longitudinal direction of the corrugated tube 100 arrange | positioned) among the recessed parts 32a and 34a of the base 32 and the cover part 34. As shown in FIG. More specifically, the support part 40 is formed in the intermediate part and both ends of the recessed parts 32a and 34a in the extending direction (separated in three places).

  In addition, this support part 40 may be comprised so that the corrugated tube 100 may be supported rotatably around the center axis | shaft, and may be comprised so that it cannot rotate.

  Further, a guide portion 60 is formed on the base portion 32 and the lid portion 34 of the main body member 30. The guide portion 60 can guide the guided member 20 along the circumferential direction of the corrugated tube 100 in a posture in which the pen tip portion 124 of the marker pen 120 is brought into contact with the outer peripheral surface of the corrugated tube 100 supported by the support portion 40. It is configured. The guide portion 60 penetrates in the radial direction with respect to the central axis of the corrugated tube 100 supported by the support portion 40 (outward from the internal space of the base portion 32 and the lid portion 34), and extends along the circumferential direction of the corrugated tube 100. It is formed in a groove shape.

  More specifically, the guide part 60 is substantially orthogonal to the central axis of the corrugated tube 100 supported by the support part 40 and is opposed to a pair of opposing members 20 that can guide the guided member 20 by contacting the guided surface 22. A guide surface 62 is provided. That is, the guide portion 60 is formed such that the pair of guide surfaces 62 extend at a substantially constant interval in the radial direction and the circumferential direction with respect to the central axis of the corrugated tube 100. This distance may be set to be larger (slightly larger here) than the dimension between the opposed guided surfaces 22 so that the tip side portion of the guided member 20 can be disposed. Here, since the guided member 20 is formed in a substantially cylindrical shape, the interval is set to be slightly larger than the outer diameter of the tip side portion.

  Further, the guide portion 60 is configured to be able to guide the guided member 20 so that at least the pen tip portion 124 of the marker pen 120 can move within the drawn range with respect to the outer peripheral surface of the corrugated tube 100 in the circumferential direction of the corrugated tube 100. Has been. For example, when the drawing range is set to a range of 120 degrees around the central axis of the corrugated tube 100, the guide unit 60 can move the pen tip portion 124 of the marker pen 120 within a range of 145 degrees around the central axis. Moreover, it is preferable that the guided member 20 is configured to be guided.

  Here, the guide part 60 is formed in two places with respect to the main body member 30 corresponding to the two peak parts 102 which are the drawing line target places of the corrugated tube 100. More specifically, the two guide portions 60 have positions in which the distance between the centers in the width direction is substantially the same as the distance between the centers in the width direction of the two peak portions 102 that are the drawn line target positions of the corrugated tube 100. Is formed. That is, when the corrugated tube 100 is supported with respect to the support portion 40, each peak portion 102 which is a drawn line target location is disposed at the center position in the width direction of each guide portion 60 and is exposed to the outside. Become.

  Also, the two guide portions 60 are respectively provided to the support portions 40 formed at the end portions and the support portions formed at the intermediate portions with respect to the support portions 40 formed at both end portions and the intermediate portion of the main body member 30. It is formed at a position between the portion 40.

  The guide portion 60 and the guided member 20 are configured to be able to regulate the inclination of the central axis of the marker pen 120 with respect to the radial direction with respect to the central axis of the corrugated tube 100 in a direction substantially orthogonal to the central axis of the corrugated tube 100. Yes. Here, the guided member 20 has a large-diameter portion 26 formed on the proximal end side thereof with a larger diameter than the distal end side portion. That is, the guided member 20 is formed with a step 26 a along the circumferential direction at the boundary between the tip side portion and the large diameter portion 26. When the marker pen 120 to which the guided member 20 is attached is tilted by a certain amount or more with respect to the radial direction with respect to the central axis of the corrugated tube 100 with the guided member 20 guided by the guide portion 60, the step 26a is formed. It abuts on the outer periphery of the guide portion 60.

  The large-diameter portion 26 is formed in a position where the inclination with respect to the radial direction is smaller than the posture in which the distal end portion of the guided member 20 contacts the corrugated tube 100 and the step 26 a contacts the outer peripheral edge of the guide portion 60. ing. With such a configuration, it is possible to prevent the ink attached to the corrugated tube 100 from being scraped off due to the contact with the guided member 20 due to the inclination of the marker pen 120. Further, ink adhesion to the guided member 20 due to the guided member 20 coming into contact with the corrugated tube 100 can be suppressed.

  The ink avoiding groove portion 70 is formed along the circumferential direction at a position corresponding to the guide portion 60 in the central axis direction of the corrugated tube 100 supported by the support portion 40 with respect to the main body member 30. More specifically, the ink avoiding groove portion 70 is formed in a groove shape that opens into the internal space of the main body member 30 along the circumferential direction from both circumferential ends of the guide portion 60. Here, in the circumferential direction of the central axis of the corrugated tube 100 supported by the support portion 40, the guide portion 60 and the ink receiving groove portion 70 are formed over the entire circumference.

  The ink avoidance groove 70 is formed to have a width dimension larger than the width dimension of the peak portion 102 of the corrugated tube 100. That is, the ink avoidance groove portion 70 is formed such that the inner peripheral surface (and the peripheral portion) thereof is not in contact with the outer peripheral surface of the peak portion 102 that is the drawn line target portion of the corrugated tube 100 supported by the support portion 40. Has been.

  Further, the ink avoidance groove portions 70 are formed at two locations on the main body member 30 corresponding to the guide portions 60 (each peak portion 102 which is a drawing target location of the corrugated tube 100).

  Further, an opening restricting portion 36 capable of restricting the opening operation is formed on the base portion 32 and the lid portion 34 of the main body member 30. The opening restricting portion 36 includes a metal washer 36 a fixed to the base portion 32 and a magnet 36 b fixed to a position facing the metal washer 36 a in a closed state with respect to the lid portion 34. The opening restricting portion 36 keeps the base portion 32 and the lid portion 34 closed with no external force acting when the magnet 36b attracts the metal washer 36a with the base portion 32 and the lid portion 34 closed. To do. However, the opening restricting portion 36 is not limited to the configuration of the metal washer 36a and the magnet 36b, and may be any configuration that can restrict the opening operation of the base portion 32 and the lid portion 34. For example, the opening restricting portion 36 may have a configuration in which a locking claw that can be locked to the base portion 32 is formed on the lid portion 34.

  Further, the lid portion 34 is formed with a handle portion 35 for opening / closing operation. The handle portion 35 is formed in a bar shape that protrudes from an end portion on the opposite side of the lid portion 34 with respect to the connecting portion with the base portion 32.

The main body support member 38 is preferably attached to the base portion 32 of the main body member 30 by screws or the like, and can be erected on the assembly drawing plate by screws or the like.

<3. Corrugated tube marking method>
Next, a corrugated tube marking method using the corrugated tube marking device 10 will be described. The marking operation on the corrugated tube 100 is performed by the marker pen 120 in the manufacturing process of the wire harness WH.

  The main body member 30 of the corrugated tube marking device 10 will be described as being supported on the assembly drawing plate 90 of the wire harness WH by the main body support member 38.

  First, the guided member 20 is attached to the distal end portion 122 of the marker pen 120. The guided member 20 is attached to the distal end portion 122 of the marker pen 120 by confirming that the center axes of the guided member 20 and the marker pen 120 substantially coincide with each other and that the pen tip portion 124 protrudes from the distal end side. It is good to be told.

  Next, the corrugated tube 100 sheathed on the wire harness WH is supported at a fixed position with respect to the main body member 30 by the support portion 40. More specifically, the handle portion 35 of the main body member 30 is operated (pushed up) to open the lid portion 34 with respect to the base portion 32, and the corrugated tube 100 is disposed in the concave portion 34a. At this time, the peak portion 102 that is the drawn line target location is disposed at a position (fixed position) disposed at a substantially intermediate position in the width direction of the guide portion 60. At this position, the corrugated tube 100 has a peak portion 102 disposed inside the concave portion and a convex portion protruding into the valley portion 104 with respect to the support portion 40 formed on the base portion 32. Become.

  Then, with the corrugated tube 100 disposed at the above position with respect to the base portion 32, the handle portion 35 is operated to close the lid portion 34 with respect to the base portion 32. Then, in the corrugated tube 100, in the same manner as described above, with respect to the support portion 40 formed on the lid portion 34, the mountain portion 102 is disposed in the concave shape portion, and the convex portion is inserted in the valley portion 104. It becomes. That is, this state is a support state with respect to the support part 40 of the corrugated tube 100, and the movement of the corrugated tube 100 in the longitudinal direction and its orthogonal direction is restricted. Further, in this state, the outer peripheral surface of each peak portion 102 which is a drawing target position of the corrugated tube 100 is exposed to the outside through the guide portion 60 and faces the ink avoiding groove portion 70 to the main body member 30. In a non-contact state.

  Next, a line is drawn on the outer peripheral surface of each peak portion 102 which is a target drawing position of the corrugated tube 100. However, this operation may be performed sequentially on two peak portions 102 or simultaneously. It may be broken. Here, an example will be described in which a line is drawn on one peak 102 and then drawn on the other peak 102.

  First, the guided member 20 attached to the marker pen 120 is placed at one end of the guide portion 60 in such a posture that the pen tip portion 124 of the marker pen 120 abuts on the outer peripheral surface of the mountain portion 102 that is the drawn line target location of the corrugated tube 100. On the side. Here, the guided member 20 is disposed with respect to the guide portion 60 corresponding to one of the peak portions 102. Preferably, the guided member 20 may be disposed at a position where it abuts against one end of the guide portion 60. In this state, the guided surface 22 of the guided member 20 contacts (partially here) the guide surface 62 of the guide portion 60, and the marker pen 120 moves and changes its posture in the longitudinal direction of the corrugated tube 100. Is regulated.

  Thereafter, the guided member 20 attached to the marker pen 120 is moved along the guide part 60 from one end side to the other end side of the guide part 60. When the corrugated tube 100 is rotatably supported with respect to the main body member 30 by the support portion 40, the corrugated tube 100 is gripped so as to restrict the rotation of the portion extending to the side of the main body member 30 and drawn. Work should be done.

  Here, the guided member 20 is drawn without directly contacting the corrugated tube 100 due to the shape in which the tip side portion of the pen tip portion 124 of the guided member 20 is projected. Further, when the marker pen 120 is tilted by a certain amount or more with respect to the radial direction with respect to the central axis of the corrugated tube 100 in a direction substantially orthogonal to the central axis of the corrugated tube 100 with the guided member 20 being guided by the guide portion 60. The step 26a of the guided member 20 comes into contact with the outer edge of the guide portion 60, and the inclination of the marker pen 120 with respect to the radial direction is restricted.

  Then, the marker pen 120 is moved until the guided member 20 is disposed on the other end side of the guide portion 60. Preferably, the guided member 20 may be moved to a position where it abuts against the other end portion with respect to the guide portion 60.

  According to the above procedure, a line is drawn on the outer peripheral surface of the peak portion 102 which is the target drawing location of the corrugated tube 100 (see the drawn portion 108 in FIG. 1). In this state, even if the corrugated tube 100 rotates around its central axis, the crest 102 to which the ink is attached faces the ink avoiding groove 70, so that the crest 102 (and the crest 102) with respect to the main body member 30. Ink adhering to the part 102 is prevented from coming into contact with the ink. Further, even if the ink adhering to the peak portion 102 of the corrugated tube 100 drips, the ink drips into the ink avoiding groove portion 70, so that the dripping ink may adhere to a portion other than the drawn line target portion of the corrugated tube 100. It is suppressed.

  When the above operation is completed, the guided member 20 is extracted from the guide portion 60. Further, the above operation is also performed on the other mountain portion 102.

  Thereafter, the handle portion 35 is operated to open the lid portion 34 with respect to the base portion 32, and the corrugated tube 100 drawn from the base portion 32 is taken out. Thus, the drawing operation for the corrugated tube 100 is completed.

  And the corrugated tube 100 used as the next drawing object should be arrange | positioned with respect to the base 32, and the drawing work should just be performed in the said procedure.

  According to the corrugated tube marking device 10 and the corrugated tube marking method using the corrugated tube marking device 10 configured as described above, the corrugated tube 100 is supported by the support portion 40 and the guided member 20 is attached to the marker pen 120. In such a state, by moving the marker pen 120 so that the guided member 20 is along the guide portion 60, a line is drawn with respect to the outer peripheral surface of the mountain portion 102, which is the drawing target location of the corrugated tube 100. Has been. For this reason, the pen point portion 124 is moved along the circumferential direction while being in contact with the outer peripheral surface of the mountain portion 102 that is the drawn line target portion of the corrugated tube 100 by the guide of the guided member 20 by the guide portion 60. . Further, since the guided member 20 is guided by the guide portion 60, the pen tip portion 124 is suppressed from contacting the main body member 30. Thereby, the ink adhesion with respect to locations other than the peak part 102 which is a drawing line target location among the corrugated tubes 100 can be suppressed.

  Further, the movement and posture change of the marker pen 120 in the axial direction of the corrugated tube 100 are regulated by the shape of the guided surface 22 of the guided member 20 and the shape of the guide surface 62 of the guide portion 60. Further, since the guided surface 22 and the guide surface 62 are substantially parallel, the guided member 20 can be smoothly guided and moved in the guide portion 60 without rattling or biting. For this reason, the pen point portion 124 of the marker pen 120 is more reliably brought into contact with the mountain portion 102 which is a drawing target location of the corrugated tube 100 in a posture substantially orthogonal to the axial direction, and is not attached to a location other than the drawing target location. Ink adhesion can be more effectively suppressed.

  In addition, since the pen point portion 124 of the marker pen 120 is surrounded by the peripheral wall portion 24 around the central axis, ink adhesion to a portion other than the outer peripheral surface of the peak portion 102 that is a drawn line target portion of the corrugated tube 100 is more effective. Can be suppressed. In addition, since there is an interval between the peripheral wall portion 24 and the pen tip portion 124 so that ink is not retained, ink accumulation between the peripheral wall portion 24 and the pen tip portion 124 is prevented, and ink accompanying this is prevented. Can be prevented from dripping.

  In addition, since the ink avoiding groove 70 is formed in the main body member 30, even if the drawn corrugated tube 100 is rotated in the circumferential direction while being supported by the support portion 40, or even if the ink dripped from the drawn portion, Ink can be prevented from adhering to the main body member 30. Further, it is possible to prevent the pen tip portion 124 of the marker pen 120 from coming into contact with the end portion of the guide portion 60 and attaching ink. As a result, it is possible to suppress the ink adhering to the guide portion 60 from adhering to the peripheral portion of the drawn line target location of the corrugated tube 100.

  Further, in the state where the guided member 20 is guided by the guide portion 60, the movement locus of the pen tip portion 124 of the marker pen 120 is substantially constant, so that the drawing operation can be performed stably and the drawing failure can be reduced. Can do.
