DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Next, an embodiment of the present invention will be described in detail with reference to the drawings as appropriate, taking as an example a case where a bolt with a washer is supplied as an example of a part having a head and a shaft portion extending from the head.

[0011] <Bolt> As shown in Fig. 1, a bolt 10 as a part supplied by a part supplying device according to an embodiment of the present invention includes a shaft portion 11 and a head portion 12 which are integrally formed, and a washer 13 fitted onto the shaft portion 11. The shaft portion 11 has a long cylindrical shape and extends from a head portion 12 which has a larger diameter than the shaft portion 11 and a short cylindrical or polygonal prism shape. A male screw portion 11a is formed on the tip end side of the shaft portion 11 (the side opposite to the head portion 12). The male screw portion 11a is not formed on the base end side of the shaft portion 11 (the head portion 12 side). The washer 13 is a part of the head portion 12, and is movable in the axial direction in a region of the shaft portion 11 where the male screw portion 11a is not formed.

[0012] <Parts supply device> As shown in Figures 2 to 4, the part supplying device 1 according to an embodiment of the present invention is a bolt supplying device that supplies bolts 10 as parts, and includes a control unit 20, a supply unit 30, a conveying unit 40, a vibration unit 50, a blowing unit 60, and a slope unit 70.

[0013] The conveying section 40 is supported by a pair of base sections 81, 81 arranged at the upstream end and downstream end of the conveying section 40, and a framework section 82 arranged on the base sections 81, 81. The vibration section 50 is arranged between the pair of base sections 81, 81. The supply section 30 is arranged to the side of the upstream section (bolt supply area 40A) of the conveying section 40. The slope section 70 is arranged to the side of the downstream section (bolt sorting area 40B) of the conveying section 40.

[0014] A wall 83 is provided at the upstream end of supply section 30 to prevent bolts 10 from falling upstream. A wall 84 is provided between the downstream end of supply section 30 and the upstream end of slope section 70 to restrict movement of bolts 10. A wall 85 is provided at the downstream end of slope section 70 to prevent bolts 10 from falling downstream.

[0015] Furthermore, on the opposite side of the conveying section 40 to the supply section 30 and the slope section 70, an intrusion prevention cover 86 is installed between the upper surfaces of the base section 81 and the vibration section 50 to prevent the bolt 10 from intruding into the gap between them. The intrusion prevention cover 86 prevents the bolt 10 from getting caught between the base section 81 and the vibration section 50, thereby preventing the vibration transmitted from the vibration section 50 to the conveying section 40 from weakening.

[0016] <Control Unit> The control unit 20 is configured with a CPU (Central Processing Unit), a ROM (Read-Only Memory), a RAM (Random Access Memory), an input / output circuit, etc. The control unit 20 controls the supply unit 30, the vibration unit 50, and the blower unit 60.

[0017] <Supply section> The supply unit 30 supplies the bolts 10 to the upstream portion of the conveying unit 40 (bolt supply area 40A), and in this embodiment, the bolts 10 are supplied to the upstream portion of the conveying unit 40 by a scooping-up motion in a position (sideways) along the upper ends of a pair of guide walls 41, 41 described below. That is, the bolts 10 are supplied to the conveying unit 40 in a position in which their axial direction is substantially parallel to the upper ends of the pair of guide walls 41, 41 in both a plan view and a side view (a viewing direction from a direction perpendicular to the plane of the guide wall 41). As shown in FIG. 5, the supply unit 30 includes a first wall 31 and a second wall 32 as fixed portions, and a first floor 33, a second floor 34, a third floor 35, and a fourth floor 36 as vertically movable portions. The supply unit 30 also includes a first operating unit 37 (see FIG. 4) that moves the first floor unit 33 up and down, and a second operating unit 38 (see FIG. 4) that moves the second floor unit 34, the third floor unit 35, and the fourth floor unit 36 ​​up and down together. The first operating unit 37 and the second operating unit 38 are each composed of a motor as a power generating unit, a power transmission mechanism that transmits the generated power, and the like, and operate based on a control signal from the control unit 20.

[0018] ≪Floor section≫ The first floor 33 is provided at a position farthest from the transport section 40 and at the lowest height as an initial position. The second floor 34 is provided at a position between the first floor 33 and the first wall 31 and at a height between the first floor 33 and the first wall 31 as an initial position. The third floor 35 is provided at a position between the first wall 31 and the second wall 32 and at the same height as the first wall 31 as an initial position. The fourth floor 36 is provided at a position between the second wall 32 and the transport section 40 and at the same height as the second wall 32 as an initial position.

[0019] The width direction dimension of the upper surface of each of the walls 31, 32 and floors 33-36 is set to a dimension that allows one bolt 10 to be placed thereon oriented horizontally along the conveying direction of the conveying section 40. With this configuration, one bolt 10 oriented horizontally along the conveying direction of the conveying section 40 can be supplied to the conveying section 40, and the shaft 11 of the bolt 10 can be easily inserted between a pair of guide walls 41, 41 described below.

[0020] <Example of the lifting part in action> With a plurality of bolts 10 placed on the first floor 33, the control unit 20 controls the first operating unit 37 to raise the first floor 33 to the height of the second floor 34. As a result, the bolts 10 move from the first floor 33 to the second floor 34 (FIG. 5 → FIG. 6).

[0021] Next, the control unit 20 controls the second operating unit 38 to raise the second floor 34, the third floor 35, and the fourth floor 36. Here, the second floor 34 rises to the height of the first wall 31, the third floor 35 rises to the height of the second wall 32, and the fourth floor 36 rises to the height of the transport unit 40. As a result, the bolt 10 moves from above the second floor 34 onto the first wall 31 (FIG. 6 → FIG. 7).

[0022] Next, the control unit 20 controls the second operating unit 38 to lower the second floor 34, the third floor 35, and the fourth floor 36 to their initial positions. This causes the bolt 10 to move from above the first wall 31 onto the third floor 35 (FIG. 7 → FIG. 8).

[0023] Next, the control unit 20 controls the second operating unit 38 to raise the second floor 34, the third floor 35, and the fourth floor 36. Here, the second floor 34 rises to the height of the first wall 31, the third floor 35 rises to the height of the second wall 32, and the fourth floor 36 rises to the height of the transport unit 40. As a result, the bolt 10 moves from above the third floor 35 to above the second wall 32 (FIG. 8 → FIG. 9).

[0024] Next, the control unit 20 controls the second operating unit 38 to lower the second floor 34, the third floor 35, and the fourth floor 36 to their initial positions. This causes the bolt 10 to move from above the second wall 32 onto the fourth floor 36 (FIG. 9 → FIG. 10).

[0025] Next, the control unit 20 controls the second operating unit 38 to raise the second floor 34, the third floor 35, and the fourth floor 36. Here, the second floor 34 rises to the height of the first wall 31, the third floor 35 rises to the height of the second wall 32, and the fourth floor 36 rises to the height of the transport unit 40. As a result, the bolts 10 move from above the fourth floor 36 to above the transport unit 40 (the bolt supply area 40A in the upstream portion) (FIG. 10 → FIG. 11).

[0026] During this operation, the control unit 20 lowers the first floor portion 33 to the initial position by appropriately controlling the first operating unit 37. As a result, the new bolt 10 is placed on the first floor portion 33.

[0027] <Transportation section> 2 and 3, the conveying unit 40 is for conveying the bolts 10, which have been supplied by the supply unit 30 to an upstream portion of the conveying unit 40 (bolt supply area 40A), to a predetermined posture and moving the bolts 10 in a straight line to the supply destination, thereby conveying the bolts 10 to the supply destination. The conveying unit 40 includes a guide rail formed of a pair of guide walls 41, 41, a plate 42, and a jam prevention cover 43.

[0028] <Guide wall> The guide walls 41, 41 are disposed with a gap therebetween that is larger than the radial dimension of the shaft 11 of the bolt 10 and smaller than the radial dimension of the head 12. The upper ends of the guide walls 41, 41 are inclined so as to become lower from the upstream side to the downstream side.

[0029] The guide walls 41, 41 are partitioned into a bolt supply area 40A upstream of the guide wall 41 and a bolt sorting area 40B downstream of the guide wall 41, 41 in the conveying direction of the bolts 10. The bolt supply area 40A is an area where the bolts 10 from the supply section 30 are supplied onto the guide walls 41, 41. The bolt sorting area 40B is an area where the bolts 10 that remain oriented horizontally are removed from above the guide walls 41, 41 and only the bolts 10 oriented vertically are selected and left.

[0030] <Plate> The plate 42 is disposed between the guide walls 41, 41 and below the upper ends of the guide walls 41, 41, and is inclined downward from the upstream side to the downstream side. The height of the plate 42 is adjustable according to the size of the bolt 10 (the axial dimension of the shank 11). The distance between the plate 42 and the guide walls 41, 41 is equal to the axial dimension of the shank 11 of the bolt 10 (more specifically, the dimension minus the thickness of the washer 13).

[0031] <Bite prevention cover> The entrapment prevention cover 43 is disposed above the downstream end of the guide wall portions 41, 41. The space formed by the entrapment prevention cover 43 and the guide wall portions 41, 41 has a shape that allows the head 12 of the bolt 10 (and the washer 13) to pass through. That is, the vertical dimension of the space is set to be slightly larger than the axial dimension of the head 12 of the bolt 10 (specifically, the sum of the axial dimension and the thickness of the washer 13) and smaller than the radial dimension of the head 12 of the bolt 10 (specifically, the radial dimension of the washer 13), and the width dimension is set to be slightly larger than the radial dimension of the head 12 of the bolt 10 (specifically, the radial dimension of the washer 13). In this embodiment, the entrapment prevention cover 43 is detachably attached to the wall portion 85.

[0032] <Vibration section> The vibration unit 50 generates vibrations and transmits the vibrations to the guide walls 41 and the plate .

[0033] <Blower section> The air blowing unit 60 blows air onto the bolts 10 supplied to the pair of guide wall portions 41, 41 based on a control signal from the control unit 20. The air blowing unit 60 includes an air generation unit 61, pipes (manifolds) 62A, 62B, a wall portion 63, a first air blowing port 64, a plurality of second air blowing ports 65, and a plurality of third air blowing ports 66. The air blowing unit 60 includes, as valves provided in the pipes 62A, 62B, a first on-off valve 67A, a second on-off valve 67B, a plurality of first adjustment valves 68A, and a plurality of second adjustment valves 68B.

[0034] <Wind Generation Unit> The wind generating unit 61 is a blower that is operated by a control signal from the control unit 20 to generate wind and supply the generated wind to the pipes 62A and 62B.

[0035] ≪Pipeline≫ The duct 62A is a system that connects the wind generation unit 61 to the first air outlet 64 and the second air outlet 65 so that air can flow through them. The duct 62B is a system that connects the wind generation unit 61 to the third air outlet 66 so that air can flow through them.

[0036] ≪Wall portion≫ The wall portion 63 is provided on the guide walls 41, 41 on the opposite side to the supply portion 30 and the slope portion 70. The wall portion 63 has air outlets 64, 65, and 66 attached thereto.

[0037] <First air outlet> The first air blowing port 64 is disposed between the upstream ends of the pair of guide walls 41, 41, and blows the air generated by the air blowing unit 61 from the upstream side to the downstream side between the pair of guide walls 41, 41. The air blown from the first air blowing port 64 hits the shaft 11 of the bolt 10 between the pair of guide walls 41, 41.

[0038] <<Second Air Vent>> The second air outlet 65 is disposed above the pair of guide walls 41, 41 at a position corresponding to the upstream portion (bolt supply area 40A) of the pair of guide walls 41, 41, and blows the wind generated by the wind generating unit 61 as downward wind from above the pair of guide walls 41, 41 toward the gap between the pair of guide walls 41, 41. In this embodiment, the wind blown from the second air outlet 65 is an obliquely downward wind that goes from the upstream side to the downstream side in the conveying direction of the pair of guide walls 41, 41 as it goes downward. The second air outlet 65 has an L-shape in a plan view. In this embodiment, the two second air outlets 65 are arranged along the conveying direction of the bolts 10 by the conveying unit 40. The wind blown from the second air outlet 65 hits the bolts 10 on the pair of guide walls 41, 41 in the upstream portion (bolt supply area 40A) of the conveying unit 40.

[0039] <Third Air Vent> The third air outlet 66 is disposed slightly above the upper ends of the pair of guide walls 41, 41 at a position corresponding to the downstream portion of the pair of guide walls 41, 41 (bolt sorting area 40B), and blows the wind generated by the wind generation unit 61 as horizontal wind intersecting the transport direction of the pair of guide walls 41, 41. In this embodiment, three third air outlets 66 are arranged along the transport direction of the bolts 10 by the transport unit 40. The air blown from the third air outlet 66 hits the bolts 10 on the pair of guide walls 41, 41 in the downstream portion of the transport unit 40 (bolt sorting area 40B).

[0040] <First opening and closing valve> The first on-off valve 67A is an electromagnetic valve provided in a flow path of a system that connects the wind generation unit 61 to the first air outlet 64 and the second air outlet 65 in the pipe 62A. Downstream of the first on-off valve 67A, the pipe 62A branches out corresponding to the first air outlet 64 and the plurality of second air outlets 65.

[0041] <Second on-off valve> The second on-off valve 67B is a solenoid valve provided in a flow path of the system that connects the wind generating unit 61 and the third air outlet 66 in the pipe 62A. Downstream of the second on-off valve 67B, the pipe 62B branches out corresponding to the multiple third air outlets 66.

[0042] <First Regulating Valve> The first regulating valve 68A is a speed control valve provided in each of the flow paths branching off from the pipe 62A corresponding to the first blowing port 64 and the second blowing port 65.

[0043] <Second Adjustment Valve> The second regulating valves 68B are speed control valves provided in the flow paths branching off from the pipe 62B in correspondence with the third blowing port 66.

[0044] The control unit 20 controls the opening and closing of the first on-off valve 67A based on the result of an operation of an operation unit (not shown) by an operator, etc., to switch between an open state in which air can be blown from the first air outlet 64 and the second air outlet 65 and a closed state in which air cannot be blown from the first air outlet 64 and the second air outlet 65. The control unit 20 also controls the opening and closing of the second on-off valve 67B based on the result of an operation of an operation unit (not shown) by an operator, etc., to switch between an open state in which air can be blown from the third air outlet 66 and a closed state in which air cannot be blown from the third air outlet 66. The control unit 20 also controls the first adjustment valve 68A corresponding to the first air outlet 64 based on the result of an operation of an operation unit (not shown) by an operator, etc., to change the discharge pressure of the air blown from the first air outlet 64. Furthermore, the control unit 20 can change the discharge pressure of the air blown from the second air outlet 65 by controlling the first regulating valve 68A corresponding to the second air outlet 65 based on the result of an operation of an operation unit (not shown) by an operator, etc. Furthermore, the control unit 20 can change the discharge pressure of the air blown from the third air outlet 66 by controlling the second regulating valve 68B corresponding to the third air outlet 66 based on the result of an operation of an operation unit (not shown) by an operator, etc.

[0045] <Slope section> The slope section 70 is a sloped section that slopes downward as it moves away from the transport section 40. The bolts 10 that fall out of the transport section 40 drop down the slope section 70 and are returned to the supply section 30.

[0046] <Example of transporting bolts> The control unit 20 controls the supply unit 30 to supply the bolts 10 onto the upstream portions of the pair of guide walls 41, 41 (bolt supply area 40A) in a horizontal orientation along the conveying direction of the conveying unit 40. Here, the control unit 20 controls the vibration unit 50 and the blower unit 60. Note that the horizontal bolts 10 supplied onto the upper ends of the pair of guide walls 41, 41 may be in an orientation in which the heads 12 are on the upstream side and the shanks 11 are on the downstream side, or in which the heads 12 are on the downstream side and the shanks 11 are on the upstream side.

[0047] The horizontally oriented bolt 10 supplied to the upper portion of the guide walls 41, 41 is caused by the vibration of the vibration unit 50 and the wind from the second air outlet 65, so that the shank 11 enters between the pair of guide walls 41, 41 and assumes a vertical position in which the head 12 (washer 13) engages with the upper ends of the pair of guide walls 41, 41. Here, the tip of the shank 11 of the bolt 10 abuts against the plate 42.

[0048] Next, the bolt 10 is transported (moved) from the upstream side to the downstream side along the inclination of the pair of guide walls 41, 41 by the vibration transmitted from the vibration unit 50 to the pair of guide walls 41, 41 and the plate 42 and by the wind from the first air outlet 64. When the bolt 10 is transported, the shaft 11 slides against the plate 42 and the head 12 (in this embodiment, the washer 13 as part of the head 12) slides against the guide walls 41, 41.

[0049] The head 12 of the bolt 10, including the washer 13, passes through the space 43a of the jam prevention cover 43 and is transported (moved) to the supply destination.

[0050] Here, when the bolt 10, still oriented horizontally in the conveying direction, is transported to the downstream part of the pair of guide walls 41, 41 (bolt sorting area 40B), the bolt 10 is removed from above the pair of guide walls 41, 41 by the wind from the third air outlet 66, and moves downward via the slope section 70.

[0051] Furthermore, the bolt 10 that remains horizontally along the transport direction cannot pass through the space of the jam prevention cover 43, and is expelled from above the pair of guide wall portions 41, 41 by the wind from the third air outlet 66, and moves downward via the slope portion 70.

[0052] Furthermore, even if the bolt 10 is vertically oriented, the washer 13 is caught on the male thread portion 11a, the shaft portion 11 does not fully enter the pair of guide wall portions 41, 41, and the head portion 12 is floating above the upper end portion of the pair of guide wall portions 41, and the bolt 10 cannot pass through the space 43a of the entrapment prevention cover 43. However, the bolt 10 with the washer 13 caught on the male thread portion 11a is released from the caught state by the vibration of the vibration portion 50 and the wind from the second air outlet 65 and moves toward the head portion 12, so that the washer 13 is prevented from reaching the entrapment prevention cover 43 while remaining caught on the male thread portion 11a.

[0053] A second supply unit (not shown) is provided downstream of the guide walls 41 (downstream of the jamming prevention cover 43) to supply the bolts 10 transported along the guide walls 41 to a supply target (for example, an engine, etc.). The second supply unit includes a detection unit (for example, a photocell, etc.) that detects the amount (number) of bolts 10 remaining in the second supply unit. When the detection unit does not detect the bolts 10 for a certain period of time while the supply unit 30 is in operation, the control unit 20 determines that the bolts 10 are clogged in the guide walls 41. When the control unit 20 determines that the bolts 10 are clogged, it alternates between an intermittent operation of intermittently opening and closing the second opening / closing valve 67B (for example, switching between opening and closing every second for 10 seconds) and a continuous operation of continuously opening the second opening / closing valve 67B (for example, switching between opening and closing every second for 10 seconds) and a continuous operation of continuously opening the second opening / closing valve 67B (for 10 seconds). When the detection unit detects the bolt 10, the control unit 20 stops the repetition of the intermittent operation and continuous operation of the second on-off valve 67B and returns to normal control.

[0054] <Startup operation example> When the component supplying device 1 is started by an operator operating an operation unit (not shown), the control unit 20 first starts the supplying unit 30, and then starts the vibration unit 50 and the air blowing unit 60. Here, the control unit 20 starts the air generation unit 61 and opens the first on-off valve 67A and the second on-off valve 67B at the same time as starting the vibration unit 50. This operation makes it possible to prevent the vibration unit 50 and the air blowing unit 60 from operating when there are no bolts 10 in the transport unit 40.

[0055] <Example of operation when stopped> When the component supply device 1 is stopped by an operator operating an operation unit (not shown), the control unit 20 first stops the supply unit 30, and then stops the vibration unit 50 and the air blowing unit 60. Here, the control unit 20 closes the first on-off valve 67A after a certain time T1 has elapsed since the vibration unit 50 was stopped, and closes the second on-off valve 67B and stops the air generating unit 61 after a certain time T2 has elapsed since the first on-off valve 67A was stopped. The certain times T1 and T2 can be appropriately set according to the performance of the supply unit 30, the conveying direction dimensions of the guide wall units 41, 41, the inclination angle of the upper end of the guide wall units 41, 41, and the like. This operation can prevent the bolts 10 from remaining in the conveying unit 40.

[0056] A part supplying device 1 according to an embodiment of the present invention comprises a supplying unit 30 which supplies a part (bolt 10) having a head 12 and a shaft portion 11 extending from the head 12, a guide rail (a pair of guide wall portions 41, 41) having a gap which is larger than the radial dimension of the shaft portion 11 and smaller than the radial dimension of the head 12, along which the part supplied by the supplying unit 30 is transported, and a blowing unit 60 which blows air onto the part supplied to the guide rail, wherein the supplying unit 30 supplies the part to the upper end of the guide rail in a position which is aligned with the upper end of the guide rail, and the blowing unit 60 blows air from above the guide rail toward the gap. Therefore, the part supplying device 1 conveys parts supplied to the conveying section 40 in a vertical position in which the shaft portion enters the gap due to the wind from the blowing section 60 and the head portion engages with the upper end portion of the guide rail, thereby preventing the occurrence of part jamming (bolt jamming), improving productivity and ultimately contributing to energy efficiency.

[0057] In the component supplying device 1, the air blowing section 60 blows the air from above the guide rail toward the gap obliquely downward along the transport direction of the guide rail. Therefore, the component supplying device 1 can more appropriately position the components vertically by applying wind obliquely downward along the conveying direction to the components at the upstream portion of the conveying section 40. This component supply device 1 can more appropriately position the bolt 10 in a vertical orientation by blowing air diagonally downward, particularly on the bolt 10 having a washer 13, to move the washer 13 toward the head 12.

[0058] In the part supplying device 1, the air blowing section 60 blows air from above the guide rail toward the gap in the upstream portion of the guide rail, and blows air horizontally that intersects with the part transport direction on the guide rail in the downstream portion of the guide rail. Therefore, the component supply device 1 uses the wind from the air blowing section 60 to orient the components vertically in the upstream portion of the conveying section 40, and removes components that are not vertically oriented from the conveying section 40 in the downstream portion of the conveying section 40 by the wind from the air blowing section 60, thereby preventing the occurrence of component jams (bolt jams), improving productivity, and ultimately contributing to energy efficiency.

[0059] In the component supplying device 1, the air blowing section 60 blows air in the gap of the guide rail from the upstream side to the downstream side of the guide rail. Therefore, the component supplying device 1 can suitably transport the vertically oriented bolts 10 by the wind from the blower section 60.

[0060] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be modified as appropriate without departing from the gist of the present invention. For example, the method of supplying bolts 10 to conveying unit 40 by supply unit 30 is not limited to the above-mentioned lifting method. In addition, the parts to be supplied are not limited to bolts 10 having washers 13. [Explanation of symbols]
