[Modes for carrying out the invention]

[0011] <Embodiment> The following describes a parts supply device according to an embodiment of the present invention, with reference to the drawings. For the sake of explanation, "front," "rear," "left," "right," "up," and "down" are defined in each figure. The "front-back direction," "left-right direction," and "up-down direction" are orthogonal to each other. The front-back direction corresponds to the "axial direction" and "conveying direction" of the present invention.

[0012] Figure 1 shows an overview of a parts supply device 10 according to an embodiment of the present invention. The parts supply device 10 includes a stirring unit 20, a rail 30, a transport path 40, an orientation determination unit 50, a transfer unit 60, and a pressing pin 70.

[0013] The stirring unit 20 is loaded with the band clamp 11. The rail 30 individually removes the band clamp 11 from the stirring unit 20. The conveying path 40 slides and conveys the band clamp 11 removed from the rail 30 by its own weight. The orientation discrimination unit 50 is provided on the front side (downstream side in the conveying direction) of the conveying path 40 to individually convey the band clamp 11 and discriminate the orientation of the band clamp 11. The delivery unit 60 is provided on the front side of the orientation discrimination unit 50 to correct the orientation of the band clamp 11. The delivery unit 60 holds the band clamp 11 in the same posture and then delivers it to the next process. The pressing pin 70 is arranged on the delivery path of the delivery unit 60.

[0014] <Band clamp 11> As shown in FIGS. 2 and 3, the band clamp 11 has a band portion 12 and a head portion 13 provided at one end of the band portion 12. The band portion 12 has a substantially strip shape with a thickness dimension T1 and a width dimension W1, and a substantially saw-tooth-shaped band locking portion 14 is provided on one side. The head portion 13 has a through hole 13A parallel to the thickness direction of the band portion 12, a locking claw 13B provided in the through hole 13A (edge portion), a contact portion 13C that contacts the vehicle body, and a substantially arrowhead-shaped vehicle body locking portion 13D erected at the center of the contact portion 13C and capable of locking to the vehicle body locking hole of the vehicle body. The contact portion 13C has a substantially suction cup shape with a substantially oval shape in plan view, and has a major axis width dimension W2 along the major axis in plan view and a minor axis width dimension W3 along the minor axis in plan view.

[0015] The band clamp 11 is arranged such that the center line C1 of the band portion 12 and the center line C2 of the contact portion 13C and the vehicle body locking portion 13D are parallel and along different planes. After the tip of the band portion 12 is inserted into the through hole 13A, the locking claw 13B locks to a predetermined portion of the band locking portion 14. Thereby, the band portion 12 is held so as not to be pulled out from the head portion 13. Such a band clamp 11 is a general-purpose band clamp. Since the band clamp 11 is made of resin, it is lightweight and flexible, and a large number of them are bundled together with a plastic bag or a rubber band so that the tips of the band portions 12 face the same direction and are circulated.

[0016] <Stirring unit 20> Returning to FIG. 1, the stirring unit 20 includes an input unit 21 for inputting the band clamps 11, a rotating drum 22 for accommodating a large number of the band clamps 11 input from the input unit 21 therein, and a drum motor 23 for rotating the rotating drum 22. The input unit 21 is disposed on the rear side of the rotating drum 22, and the front end thereof is inserted into the rotating drum 22. The input unit 21 is provided with an inclined surface 24 that approaches the lower side as it goes toward the front side. Thereby, when a large number of the band clamps 11 are input into the input unit 21, the large number of the band clamps 11 can be guided by the inclined surface 24 and input into the rotating drum 22.

[0017] The rotating drum 22 has a cylindrical shape, and a plurality of stirring blades (not shown) are provided on the inner peripheral surface thereof. The drum motor 23 has rotating rollers 25, 25 supported on the rotating shaft, and the rotating rollers 25, 25 are in contact with the outer peripheral surface of the rotating drum 22. The rotating drum 22 and the drum motor 23 are arranged so as to approach the upper side as they go toward the front side. Such a stirring unit 20 stirs a large number of the band clamps 11 input therein as the rotating drum 22 driven by the drum motor 23 rotates.

[0018] The band clamps 11 stirred inside the rotating drum 22 are individually supplied to the rail 30 by their own weight. When a large number of the band clamps 11 are input into the input unit 21, the direction of protrusion of the head portion 13 of each band clamp 11 is not a concern, and it is not necessary for an operator to perform complicated operations when inputting the band clamps 11.

[0019] <Rail 30> The rail 30 includes a first shaft portion 31 and a second shaft portion 32 arranged in parallel with each other from the rotation center portion of the rotating drum 22 toward the front side, a spiral member 33 along the peripheral surface of the first shaft portion 31, a plate 34 (abutting portion) provided above the second shaft portion 32, and a guide plate 35 provided substantially in parallel with the first shaft portion 31 from a position closer to the front side than the plate 34.

[0020] As shown in Figures 4 and 5, the first shaft portion 31 is provided with a spiral projection on its circumferential surface by passing a spiral member 33 through it. The spiral member 33 is formed by winding a wire spirally at equal pitches. The diameter dimension D1 of the wire of the spiral member 33 is larger than the thickness dimension T1 of the band portion 12.

[0021] The winding spacing P1 of the convex spiral member 33 is set to be greater than the width W1 of the band portion 12 and smaller than the long axis width W2 of the contact portion 13C. In addition, the spacing G1 between the circumferential surface of the first shaft portion 31 and the circumferential surface of the second shaft portion 32, which are located behind the plate 34, is set to be greater than the diameter D1 of the wire and the width W1 of the band portion 12, and smaller than the short axis width W3 of the contact portion 13C.

[0022] The helical member 33 is rotated counterclockwise when viewed from the front by a rail motor 36 (see Figure 1) which is arranged on the same axis as the first shaft portion 31. The first shaft portion 31 may rotate in synchronization with the helical member 33. The first shaft portion 31 and the second shaft portion 32 are provided extending from inside the rotating drum 22 to outside the rotating drum 22.

[0023] As shown in Figure 4, the second shaft portion 32 is partially missing on the front side of the plate 34. In this embodiment, the second shaft portion 32 is missing in the portion that faces the plate 34 vertically from the rear end to the front end. Furthermore, the separation dimension G2 between the circumferential surface of the first shaft portion 31 in front of the plate 34 and the circumferential surface of the second shaft portion 32 is set to be larger than the rear separation dimension G1 described above.

[0024] As shown in Figure 5, the plate 34 is provided above the second shaft portion 32. The plate 34 is not provided above the first shaft portion 31. The plate 34 can only contact the head portion 13 of the band clamp 11. As shown in Figure 4, the plate 34 has a stopper surface 34A, which is a flat surface substantially perpendicular to the axis of the second shaft portion 32. The guide plate 35 has a guide surface 35A parallel to the axis of the first shaft portion 31 and is continuous from the plate 34 to the end (front end) of the helical member 33.

[0025] In this rail 30, the band clamp 11, which has been agitated in the rotating drum 22 of the agitation unit 20, is inserted from the tip of the band portion 12 between the first shaft portion 31 and the second shaft portion 32. At this time, the band portion 12 is housed between the windings of the helical member 33 between the first shaft portion 31 and the second shaft portion 32. Furthermore, the band portion 12 and the head portion 13 are arranged at different levels so that the center line C1 of the band portion 12 and the center line C2 of the vehicle body locking portion 13D are parallel and lie along different planes. As a result, the contact portion 13C gets caught on the first shaft portion 31 or the second shaft portion 32 and cannot pass downward. This holds the band clamp 11 in a state where the band portion 12 hangs down between the first shaft portion 31 and the second shaft portion 32.

[0026] Here, the band clamp 11 is either in a forward orientation state with the head portion 13 protruding to the left (dotted line in Figure 4) or in a wrong orientation state with the head portion 13 protruding to the right (dash-dotted line in Figure 4). The forward-oriented band clamp 11 is guided by the first shaft portion 31 and the helical member 33 as the helical member 33 rotates, and is transported to the front. At this time, the plate 34 does not interfere with the forward-oriented band clamp 11.

[0027] On the other hand, when the band clamp 11 is misoriented, as the spiral member 33 rotates, the head portion 13 comes into contact with the abutment surface 34A of the plate 34. In this state, as the spiral member 33 rotates further, it rotates around a line along the longitudinal direction (vertical direction) of the band portion 12 (as shown by the dashed line in Figure 4), and its orientation is corrected to the correct orientation. After that, it is guided by the first shaft portion 31 and the spiral member 33 and transported forward along the guide surface 35A of the guide plate 35. The band clamp 11, as described above, falls into the transport path 40, which is the next process, due to its own weight at the end of the rail 30 (the front end).

[0028] <Transportation Route 40> Returning to Figure 1, the transport path 40 has a pair of transport guide plates 41, 41. The transport guide plates 41, 41 are arranged along the same plane and spaced a predetermined distance apart to form a transport slit 42. The transport path 40 is inclined such that the transport guide plates 41, 41 move downwards as they approach the front side of the transport slit 42. The width dimension G3 of the transport slit 42 is set to be greater than the thickness dimension T1 of the band portion 12 and less than the width dimension W1 of the band portion 12. In such a transport path 40, the band clamp 11 that has fallen from the rail 30 is inserted into the transport slit 42 while remaining in its upright orientation, and is transported down along the transport slit 42 by its own weight and supplied to the orientation determination unit 50, which is the next process and part of the transport path 40.

[0029] <Orientation discrimination unit 50> As shown in Figures 6 and 7, the orientation determination unit 50 includes a pair of determination guide plates 51 and 52 positioned in front of the transport path 40, detection units 53 and 54 provided on the determination guide plates 51 and 52 respectively, and an individual transport unit (not shown) positioned directly below the determination guide plates 51 and 52. The determination guide plates 51 and 52 are arranged substantially horizontally and spaced apart by a predetermined distance to form a determination slit 55.

[0030] This orientation determination unit 50 takes over the band clamp 11 from the end of the transport slit 42 of the transport path 40, and determination guide plates 51 and 52 are arranged so that the band clamp 11 can be transported individually. The spacing dimension G4 of the determination slit 55 is set to be larger than the thickness dimension T1 of the band portion 12 and smaller than the width dimension W1 of the band portion 12, similar to the width dimension G2 of the transport slit 42 described above.

[0031] The detection units 53 and 54 are so-called non-contact sensors, either photoelectric or capacitive. Only one of the detection units 53 or 54 reacts depending on the orientation of the head portion 13 of the unit 11 that has been individually transported along the discrimination slit 55 by the individual transport unit, thereby enabling the detection of the orientation of the head portion 13 of the band clamp 11. Specifically, if a mis-oriented band clamp 11 is transported along the discrimination slit 55 (see dashed line in Figure 7), the detection unit 53 determines that it is mis-oriented, and if a correctly-oriented band clamp 11 is transported along the discrimination slit 55 (see solid line in Figure 7), the detection unit 54 determines that it is mis-oriented.

[0032] Basically, the rail 30 supplies the band clamp 11 to the transport path 40, which is the next process, in a correctly oriented state. However, when the band clamp 11 is dropped from the rail 30 to the transport path 40 by its own weight, there is a possibility that the band portion 12 may be inserted into the transport slit 42 in a mis-oriented state. For this reason, the orientation determination unit 50 is designed to reconfirm whether the band clamp 11 is correctly oriented or mis-oriented. The individual transport unit grips the tip of the band portion 12 that hangs downward from the determination slit 55. The individual transport unit is a mechanism that moves the band clamp 11 forward along the determination slit 55 using, for example, a motor or actuator, and its structure is arbitrary. Such an orientation determination unit 50 is part of the transport path 40.

[0033] <Transfer section 60 and pressing pin 70> As shown in Figure 6, the transfer section 60 has a support section 61 provided in front of the orientation determination section 50 and a gripping section (chuck) 63 supported at the lower end of the support section 61.

[0034] The support portion 61 is rotatable around an axis running vertically by a motor, actuator, etc. Furthermore, the support portion 61 is rotatable around an axis running horizontally by a motor, actuator, etc., and rotates between a gripping position with the gripping portion 63 facing downwards and a transfer position with the gripping portion 63 facing forwards. Additionally, the support portion 61 is slidable in the front-rear direction by a motor, actuator, etc.

[0035] The gripping portion 63 has contact pieces 66 and 67 that can grip the head portion 13 of the band clamp 11 in front of the orientation determination portion 50. The contact pieces 66 and 67 move closer to and further apart from each other. The support portion 61 rotates the gripping portion 63 180 degrees around an axis along the vertical direction so that the relative positions of the contact pieces 66 and 67 are reversed when the band clamp 11 is misoriented, and then rotates the gripping portion 63 180 degrees again around the axis along the vertical direction so that the contact pieces 66 and 67 are in the correct position.

[0036] Such a transfer unit 60 operates in accordance with the orientation of the head unit 13 detected by the orientation determination unit 50. The gripping unit 63 is waiting, separated from each other, in the normal position where the contact piece 66 is on the right and the contact piece 67 is on the left, assuming that the head unit 13 of the band clamp 11 is oriented correctly.

[0037] When the band clamp 11 is transported along the discrimination slit 55 in a positive orientation, the detection unit 54 detects that it is positively oriented. The transfer unit 60 is waiting with the contact pieces 66 and 67 of the gripping unit 63 separated, and then the contact pieces 66 and 67 come close together so that the positively oriented band clamp 11 is gripped by the gripping unit 63.

[0038] On the other hand, if the band clamp 11 is transported along the discrimination slit 55 in a mis-oriented state, the detection unit 53 detects that it is mis-oriented. In this case, the transfer unit 60 uses the support unit 61 to rotate the gripping unit 63 180 degrees around an axis in the vertical direction so that the left and right positions of the contact pieces 66 and 67 are reversed. Next, the transfer unit 60 uses the support unit 61 to rotate the gripping unit 63 180 degrees again so that the mis-oriented band clamp 11 is gripped by the gripping unit 63 with the contact pieces 66 and 67 in close proximity, and the contact pieces 66 and 67 are in their normal positions.

[0039] This results in the same condition as when the band clamp 11 is transported along the discrimination slit 55 in a correctly oriented state. Then, the support portion 61 rotates the gripping portion 63 by 90 degrees around an axis in the vertical direction, so that the contact piece 66 is on the front side and the contact piece 67 is on the rear side, as shown in Figure 8(A). At this time, the band clamp 11 is oriented so that the thickness direction of the band portion 12 is aligned with the front-rear direction. In other words, the band clamp 11 transported along the discrimination slit 55, whether correctly oriented or incorrectly oriented, can ultimately be passed on to the next process in the same orientation.

[0040] Next, as shown in Figure 8(B), the transfer section 60 rotates the support section 61 by approximately 90 degrees from the gripping position to the transfer position. This causes the band section 12 to pass through contact with the pressure pin 70 provided on the rotation path of the band clamp 11. The pressure pin 70 is positioned to traverse the rotation path of the band clamp 11. As shown in Figure 8(C), the band clamp 11 is oriented so that the tip of the band section 12 faces downstream in the conveying direction. By passing the band section 12 through contact with the pressure pin 70, any deformations such as warping that occurred in the band section 12 during the manufacturing of the band clamp 11 are corrected.

[0041] To explain in more detail, in the example shown in Figure 8(A), the band portion 12 is bent at an angle. As shown in Figure 8(B), by pressing the band portion 12 against the pressing pin 70, the bend of the band portion 12 is eliminated, as shown in Figure 8(C). After that, the support portion 61 slides forward to hand over the band clamp 11 to the next step.

[0042] <Effects of the Embodiment> As described above, according to the parts supply device 10 of the present invention, the device comprises a rotating drum 22 that accommodates a plurality of band clamps 11, and a rail 30 having a first shaft portion 31 and a second shaft portion 32. The band clamps 11 are transported by the rotation of the first shaft portion 31, which has a protrusion provided by a helical member 33, around its axis. Therefore, even if the band clamps 11 have a complex shape, are lightweight overall, and are flexible, the band clamps 11 can be supplied to the next process in the same orientation.

[0043] Furthermore, according to the parts supply device 10 according to an embodiment of the present invention, the band clamp 11 has a band portion 12 and a head portion 13, and the separation dimension G1 between the first shaft portion 31 and the second shaft portion 32 is set to be larger than the width dimension W1 of the band portion 12 and smaller than the short axis width dimension W3 of the contact portion 13C. As a result, the band portion 12 is provided to pass between the first shaft portion 31 and the second shaft portion 32, but the head portion 13 is not provided to pass through, so that the band clamps 11 can be transported individually by the rail 30.

[0044] Furthermore, according to the component supply device 10 of the present invention, it is equipped with a plate 34 that the head portion 13 of the conveyed band clamp 11 abuts against and rotates. Therefore, the band clamp 11 that is conveyed in the wrong orientation on the rail 30 can be corrected to the correct orientation.

[0045] Furthermore, according to the parts supply device 10 according to the embodiment of the present invention, since a portion of the second shaft portion 32 is missing on the front side of the plate 34, the band clamp 11 can be reliably transported by the first shaft portion 31.

[0046] Furthermore, according to the component supply device 10 of the embodiment of the present invention, the pitch of the spiral member 33, which is a spiral-shaped protrusion, is set to a size that accommodates only one head portion 13. Therefore, the band clamps 11 can be transported individually.

[0047] Furthermore, according to the component supply device 10 according to an embodiment of the present invention, it includes a transport path 40 for transporting the band clamp 11 with its head portion 13 hooked onto the edge of the discrimination slit 55, detection units (sensors) 53 and 54 provided on the transport path 40 for detecting the orientation of the head portion, and a gripping unit (chuck) that grips the band clamp 11 transported along the discrimination slit 55 and rotates according to the detection results of the detection units 53 and 54 to unify the orientation of the head portion 13. Therefore, a band clamp 11 that has become misoriented in the transport path 40 can be corrected to the correct orientation.

[0048] Furthermore, according to the component supply device 10 of the embodiment of the present invention, it includes a transport path 40 for transporting the band clamp 11 with its head portion 13 hooked onto the edge of the discrimination slit 55, a gripping portion (chuck) 63 for gripping the band clamp 11 transported along the discrimination slit 55, and a pressing pin 70 positioned on the path through which the band clamp 11 is transferred by the gripping portion 63. Therefore, deformations such as warping that occur in the band portion 12 during the manufacturing of the band clamp 11 can be corrected.

[0049] <Other forms> It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. Furthermore, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention.

[0050] In the embodiment described above, a plate 34 is provided on the rail 30 to transfer the band clamp 11 in a positive orientation. Furthermore, the chuck 63 is rotated according to the detection results of the detection sensors 53 and 54, but this is not the only configuration. Only the plate 34 or the detection sensors 53 and 54 may be provided.
