  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for implementing a tube clip mounting device according to the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a tube clip mounting device according to this embodiment, and FIG. 2 is a schematic front sectional view partially showing the tube clip mounting device. 3 is a perspective view of the tube clip, and FIG. 4 is a perspective view of the tube to which the tube clip is attached.

  First, a tube clip targeted by the tube clip mounting device according to the embodiment will be described with reference to FIG. The tube clip 12 is formed at one end of an elastically deformable leaf spring (metal material (wire)) in a ring shape (circular shape), and at both ends of the ring portion 12a, and the ring portion 12a is expanded. It consists of an enlarged diameter clip portion 12b.

  The diameter-enlarged clip portion 12b includes a first knob 12b1 in which a part of one end of the ring portion 12a is extended and protrudes outward in the axial direction, and the other end is extended and protrudes outward in the axial direction. The second knob 12b3 is formed with an engagement hole 12b2 through which the first knob 12b1 intersects.

  When the tube clip 12 presses the diameter-enlarged clip portion 12b from both sides, specifically, when the first and second knobs 12b1 and 12b3 are pressed in directions close to each other, the ring portion 12a is expanded in diameter, When released, it is restored by the elastic force and returns to the shape shown in FIG.

  The tube 14 is made of a rubber tube used for a vehicle fuel system or the like, and has a circular cross section having an outer diameter corresponding to the inner diameter of the ring portion 12a as shown in FIG. When the expanded clip portion 12b of the tube clip 12 is pressed and the ring portion 12a is expanded in diameter, the tube 14 is inserted into the ring portion 12a, and when the expanded clip portion 12b is released from the press, the ring portion 12a. It is pinched by. FIG. 4 shows a tube 14 to which two tube clips 12 are attached.

  A marking 16 indicating the mounting direction of the tube clip 12 and the like is provided on the outer wall of the tube 14. Specifically, a circular marking 16 of a predetermined color (for example, yellow or white) having a diameter of about 2 mm to 4 mm is preliminarily marked near the end of the tube 14 in accordance with the assembly direction of the tube clip 12.

  Based on the above, a tube clip mounting device (hereinafter referred to as “device”) will be described. As shown in FIGS. 1 and 2, the device 10 is provided with a plate-like base member 20, a through hole 22 a for inserting the tube 14 and a recess 22 b for receiving the tube clip 12. A tube 22 having a diameter, a tube clip expanding means 24 for expanding the ring portion 12a of the tube clip 12 accommodated in the recess 22b, and a tube capable of adjusting the insertion depth of the tube 14 inserted into the through hole 22a. An insertion depth adjusting means 26 and a controller 28 for controlling the operation of the tube clip diameter expanding means 24 and the tube insertion depth adjusting means 26 are provided. In addition, the device 10 is provided with a switch 30 that is provided so as to be freely operated by an operator and that generates an output when operated (pressed) by the operator.

  The base 22 is made of a resin or metal block member formed in a rectangular parallelepiped shape, and the through hole 22a and the concave portion 22b are formed on the upper surface.

  The through-hole 22a is a hole having a circular cross section (a cross section perpendicular to the axial direction of the through-hole 22a is a circle) having a diameter slightly larger than the outer diameter of the tube 14 so that the tube 14 can be inserted. As shown in FIG. 2, it penetrates through the ceiling portion of the base 22 and opens into a cavity 22 c formed inside the base 22.

  The concave portion 22b is formed in a cylindrical shape having a predetermined depth (a depth corresponding to the height of the ring portion 12a from the upper surface of the base 22) formed around the through hole 22a or an inverted truncated cone as shown in FIG. It consists of a shape (tapered) groove | channel (recessed part).

  The cavity 22c detects the color and position of the marking 16 applied to the outer wall of the tube 14 inserted from the through hole 22a. When the detected color is a predetermined color and the detected position is a predetermined position A marking detecting means (tube insertion detecting means) 32 for generating an output is installed.

  The marking detection means 32 irradiates light toward the marking 16 of the tube 14 (in the direction of the arrow in FIG. 2) using a light emitting element composed of LEDs of three colors, red, blue, and green, and the ratio of the reflected light. From this, the color and position of the marking 16 are detected.

  The tube clip diameter increasing means 24 is attached to the side surface of the base 22, and includes an air cylinder 24a, a plunger 24b accommodated in the air cylinder 24a, and a compressor 24c for supplying air (compressed air) to the air cylinder 24a. Is provided.

  FIG. 5 is an explanatory view of the tube clip diameter expanding means 24.

  When air is supplied from the compressor 24c to the air cylinder 24a, the plunger 24b extends in the plunger movement groove 22d formed near the upper surface of the base 22, as shown in FIG. The knob 12b1 is pressed. At this time, since the second knob 12b3 is supported by the tube clip support wall (stopper) 22e of the base 22, the ring portion 12a expands in diameter as the plunger 24b extends. When the supply of air is stopped, the plunger 24b is retracted to the initial position by the repulsive force of the enlarged diameter clip portion 12b.

  Returning to the description of FIGS. 1 and 2, the tube insertion depth adjusting means 26 is attached to the side of the base 22 opposite to the side on which the tube clip diameter increasing means 24 is attached. Similar to the diameter means 24, an air cylinder 26a, a plunger (regulating member) 26b accommodated in the air cylinder 26a, and a compressor 26c for supplying air to the air cylinder 26a are provided.

  FIG. 6 is an explanatory view of the tube insertion depth adjusting means 26.

  When air is supplied from the compressor 26c to the air cylinder 26a, the plunger 26b extends in the hollow portion 22c so as to cross the insertion path of the tube 14 (arrow A in the figure). Accordingly, when the plunger 26b extends by a predetermined distance, the insertion path of the tube 14 is blocked by the plunger 26b as shown in FIG. As a result, the distal end portion of the tube 14 inserted from the through-hole 22a abuts on the plunger 26b, and the tube 14 cannot advance further (cannot be inserted further deeper (insertion of the tube 14 is restricted)). .

  FIG. 6 shows a state in which the insertion depth of the tube 14 is changed from d1 to d2 by the plunger 26b extending a predetermined distance. That is, in this embodiment, the insertion depth of the tube 14 can be adjusted in two stages, d1 and d2, and when the insertion depth of the tube 14 is d1, the tube clip 12 is mounted at the position P1 of the tube 14, When the insertion depth 14 is d2, the tube clip 12 is attached to the position P2 of the tube 14.

  As described above, since the plunger 26b prevents the insertion of the tube 14, the surface 26b1 of the plunger 26b that comes into contact with the distal end portion of the tube 14 is formed in a flat shape so as to easily prevent the insertion of the tube 14. At the same time, it has a certain width enough to prevent the tube 14 from being inserted. Therefore, in this embodiment, the plunger 26b is constituted by a plate-like member having a plate shape. However, as long as insertion of the tube 14 can be prevented, the shape of the plunger 26b is not limited to a specific shape, and may be, for example, a rod-like member having a semicircular cross-sectional view in which only the upper portion is formed flat.

  Further, as described above, in this embodiment, the tube insertion depth adjusting means 26 can adjust the insertion depth of the tube 14 in two stages, d1 and d2. For example, the plunger 26b is disposed in the hollow portion 22c. The tube 14 may be configured so as to be movable in the vertical direction (arrow B in the figure) on the insertion path of the tube 14 so that the insertion depth of the tube 14 can be adjusted in more fine steps.

  Furthermore, although illustration is omitted, not a single air cylinder 26a but a plurality of air cylinders 26a are installed along the side surface of the base 22, and corresponding to the plurality of plungers 26b according to the insertion depth of the tube 14. The plunger 26b may be extended (in this case, the insertion depth of the tube 14 can be switched by a number corresponding to the number of installed air cylinders 26a).

  The plunger 26b is returned to the initial position shown in FIG. 2 when the supply of air is stopped, but any method may be used for returning the plunger 26b to the initial position. That is, for example, a spring or the like may be provided in the air cylinder 26a, and the plunger 26b may be returned to the initial position by the urging force of the spring, or the plunger 26b is contracted by switching the air supply destination to the initial position. You may make it return.

  Returning to the description of FIGS. 1 and 2, the controller 28 comprises a microcomputer equipped with a CPU, a memory, etc., and the tube clip diameter expanding means 24 (compressor 24c), the tube insertion depth adjusting means 26 (compressor 26c), and a switch. 30 and the marking detection means 32.

  When the controller 28 detects the output of the switch 30, the air is supplied to the air cylinder 24a of the tube clip diameter increasing means 24 to operate the plunger 24b, and the diameter of the ring portion 12a of the tube clip 12 accommodated in the recess 22b is increased. .

  After that, when the tube 14 is inserted from the through hole 22a and the output of the marking detection means 32 is detected, the controller 28 stops the diameter expansion of the ring portion 12a by the tube clip diameter increasing means 24, specifically, the tube clip diameter increasing means. The supply of air is stopped with respect to 24, and the operation of the plunger 24b is stopped. As a result, the plunger 24 b is returned to the initial position by the repulsive force (restoring force) of the diameter-enlarged clip portion 12 b, and the tube clip 12 is attached to a predetermined position of the tube 14.

  The above operation will be described with reference to the flowchart of FIG. FIG. 7 is a flowchart showing the control operation of the controller 28, and FIG. 8 is an operation explanatory diagram showing the operation procedure of the apparatus 10. In FIG. 7, S indicates a processing step of the program.

  In the following description, it is first determined in S10 whether or not the switch 30 has been pressed (ON). If the result is negative, the process does not proceed to the next process. It is determined whether or not the direction of the tube clip 12 is a predetermined direction. Although detailed description about the determination of the orientation of the tube clip 12 is omitted, for example, light is applied to the enlarged clip portion 12b of the tube clip 12 using an optical sensor, and the orientation of the tube clip 12 is determined based on the reflected light. to decide.

  If NO in S12, that is, if it is determined that the tube clip 12 is not accommodated in the predetermined direction (the direction of the tube clip 12 is accommodated upside down), the process does not proceed to the next process, affirmative, That is, when it is determined that the tube clip 12 is accommodated in a predetermined direction, the process proceeds to S14, and the diameter of the ring portion 12a of the tube clip 12 accommodated in the recess 22b is expanded by the tube clip diameter increasing means 24. By expanding the diameter of the ring portion 12a of the tube clip 12, an operator can insert the tube 14 into the through hole 22a.

  Next, in S16, it is determined whether or not the color of the marking 16 of the tube 14 detected by the marking detection means 32 is a predetermined color and the position is at a predetermined position.

  As described above, the color of the marking 16 indicates the direction in which the tube clip 12 is attached to the tube 14. Accordingly, when a plurality of tube clips 12 are attached to one tube 14 and the orientation of the tube clips 12 at the time of attachment is different, the default color of the marking 16 is different for each tube clip 12 (tubes). A predetermined color of a different color marking is predetermined for each clip 12).

  More specifically, for example, when two tube clips 12 are mounted on one tube 14 and the mounting directions of the first tube clip 12 and the second tube clip 12 are different. Is set so that the default colors of the markings 16 are different between the first and second tube clips 12 (for example, the first tube clip 12 is white and the second tube clip 12 is Is set to yellow).

  Therefore, when the first tube clip 12 is attached, for example, if it is detected that the white marking 16 is in a predetermined position, an affirmative result is obtained in S16, and when the second tube clip 12 is attached, the yellow tube clip 12 is yellow. If it is detected that the marking 16 is in a predetermined position, an affirmative determination is made in S16.

  In this embodiment, the predetermined color marking 16 is in a predetermined position. In other words, the tube 14 is in contact with the floor surface of the hollow portion 22c and the plunger 26b and set to a predetermined depth. Means.

  Returning to the description of the flow chart of FIG. 7, in S 16, that is, when the color of the marking 16 of the tube 14 detected by the marking detection means 32 is not the default color or the position is not the predetermined position, the next processing is performed. However, when the determination is affirmative, the process proceeds to S18 where the diameter of the ring portion 12a of the tube clip 12 by the tube clip diameter increasing means 24 is stopped and the tube clip 12 is attached to the tube 14. When the tube clip 12 is attached to the tube 14, the tube 14 is once pulled out from the through hole 22a by an operator (see FIG. 8A).

  Next, in S20, an integer type variable n (this variable n is initialized (reset to zero) at the time of program execution) is incremented (1 is added to the variable n). The variable n is a variable for determining how many tube clips 12 are currently attached to the tube 14. For example, when the first tube clip 12 is attached, the variable n is incremented in S20. 1

  Next, in S22, it is determined whether or not the variable n has reached the specified number. The specified number of times is set to a number corresponding to the number of tube clips 12 to be attached to the tube 14. Therefore, for example, when two tube clips 12 are attached to the tube 14, the specified number of times is set to two.

  No in S22, that is, when the variable n has not reached the specified number of times, in other words, when all the tube clips 12 are not yet attached to the tube 14, the process proceeds to S24 to prepare for the attachment of the next tube clip 12. Switch the insertion depth of the tube 14 (decrease the insertion depth of the tube 14 (make it shallow)). Specifically, air is supplied to the air cylinder 26a to extend the plunger 26b by a predetermined distance. After switching the insertion depth of the tube 14, the process returns to S10.

  On the other hand, when S22 is positive, that is, when the variable n has reached the specified number of times and all the tube clips 12 have been attached to the tube 14 (see FIG. 8B), the process proceeds to S26 and the insertion depth of the tube 14 is initialized. Return to the position (reset) to end the process.

  FIG. 9 is a schematic front sectional view similar to FIG. 6, showing a modification of the tube insertion depth adjusting means 24.

  The tube insertion depth adjusting means 26 ′ in the modified example is similar to the tube insertion depth adjusting means 26 in the above-described embodiment, and includes an air cylinder 26a ′, a plunger 26b ′ accommodated inside the air cylinder 26a ′, and an air A compressor (not shown) for supplying air to the cylinder 26a '.

  However, as shown in FIG. 9, the tube insertion depth adjusting means 26 ′ in the modified example is provided below the base 22, more specifically, on the floor portion of the cavity 22c, that is, the base member 20, Is provided, the plunger 26b 'is configured to extend in the vertical direction in the cavity 22c. Therefore, the insertion depth of the tube 14 can be adjusted by controlling the amount of expansion / contraction of the plunger 26b '.

  As described above, according to the embodiment of the present invention, the ring portion 12a is made of a circular elastically deformable wire (metal material), and the enlarged clip portion 12b is formed by extending both ends of the wire. In the tube clip mounting apparatus 10 for mounting the tube clip 12 to the tube 14, the ring clip portion is accommodated in a recess 22b formed around a through hole 22a into which the tube can be inserted. Since the tube clip diameter increasing means 24 that expands the diameter via the tube and the tube insertion depth adjusting means 26 that can adjust the insertion depth of the tube inserted into the through hole are provided, Even when a single tube clip 12 is attached, the insertion depth of the tube 14 can be adjusted by the tube insertion depth adjusting means 26. It can be done to ease.

  Further, the tube insertion depth adjusting means has a restricting member (plunger) 26b that abuts the distal end portion of the tube inserted into the through hole and restricts the insertion depth of the tube. Since the insertion depth of the tube is adjusted by moving the position, the distal end portion of the tube 14 inserted into the through hole 22a abuts on the plunger 26b, and the insertion depth of the tube 14 is automatically set. Therefore, the insertion depth of the tube 14 can be adjusted more easily. Moreover, the insertion depth of the tube 14 can be adjusted with a simple configuration using only the plunger 26b.

  Moreover, since it comprised so that the tube insertion detection means (marking detection means) 32 which detects that the front-end | tip part of the tube inserted in the said through-hole contact | abutted to the said regulation member was comprised, for example, the front-end | tip part of the tube 14 may be provided. The tube clip 12 can be attached to the tube 14 when it is detected that the plunger 26b is abutted, and the tube clip 12 can be attached efficiently.

  In addition, the tube clip diameter increasing means is configured to stop the diameter expansion of the ring portion when it is detected that the distal end portion of the tube is in contact with the regulating member (S16, S18). The tube clip 12 can be attached more efficiently.

  Further, the tube insertion depth adjusting means moves the regulating member in the direction of the through-hole each time the diameter of the ring portion is stopped by the tube clip diameter increasing means and the tube clip is attached to the tube. Since the insertion depth of the tube is reduced (S20 to S24), it is possible to more efficiently attach the plurality of tube clips 12 to one tube 14.

  In the embodiment, the tube insertion depth adjusting means 26 is composed of an air cylinder 26a, a plunger 26b, and a compressor 26c, and the plunger 26b is expanded and contracted by supplying air to the air cylinder 26a. The plunger 26b may be expanded and contracted by using a fluid pressure cylinder or a motor instead of the air cylinder 26a.

  In addition, the supply of air, in other words, the expansion and contraction of the plunger 26b is automatically performed in response to a command from the controller 28. However, the plunger 26b can be expanded and contracted by a manual operation. Alternatively, the plunger 26b may be manually expanded and contracted.

  Further, whether or not the distal end portion of the tube 14 is in contact with the plunger 26b is determined by detecting the position of the marking 16 provided on the outer wall of the tube 14, but other than that, for example, on the surface 26b1 of the plunger 26 A pressure sensor or the like may be provided to determine whether or not the distal end portion of the tube 14 has come into contact with the plunger 26b, and the determination method is not limited to a specific method.

  Moreover, although the example in which the tube insertion depth adjusting means 26 is attached to the side of the base 22 opposite to the side on which the tube clip diameter increasing means 24 is attached has been shown, this is merely an example, As long as the insertion path of the tube 14 can be blocked, the tube insertion depth adjusting means 26 may be attached to any of the four surfaces constituting the side surface of the base 22.
