[0013] An embodiment of the present disclosure will be described below with reference to the drawings. Fig. 1A is a perspective view showing a component supplying device 1 in a state where a tool is installed. Fig. 1B is a perspective view showing the component supplying device 1 in a state where a tool is not installed. Fig. 2 is a front view showing the component supplying device 1. Fig. 3 is a right side view showing the component supplying device 1. Fig. 4 is a left side view showing the component supplying device 1. Fig. 5 is a rear view showing the component supplying device 1.

[0014] The component supplying device 1 is a device that supplies components to be supplied. The components to be supplied are metallic components that can be attracted by magnetic force. The component supplying device 1 includes a plurality of wires 10 that are spaced apart from one another and move up and down, a wire support unit 11, a plurality of magnetic material units 12, a magnetic material unit storage unit 20, a first component storage unit 30, component transfer units 40, 42, 44, a second component storage unit 50, and a tool installation unit 60. These components are supported by a frame.

[0015] The plurality of wires 10 are arranged to extend substantially vertically. Upper ends of the plurality of wires 10 are connected to a wire support portion 11 that moves up and down. Lower ends of the plurality of wires 10 are connected to a plurality of magnetic material portions 12. The plurality of wires 10 have a length that allows the wires 10 to reach the first component receiving portion 30 when the wires 10 are at their lowest points.

[0016] FIG. 6 is an enlarged view showing multiple magnetic material portions 12 attached to multiple wires 10. The multiple magnetic material portions 12 are components made of a magnetic material. The multiple magnetic material portions 12 are attached to the lower ends of the multiple wires 10, respectively. The magnetic material portions 12 have through holes in their longitudinal direction, into which the wires 10 are inserted. In addition, the ends of the wires 10 inserted into the magnetic material portions 12 are crimped to prevent the magnetic material portions 12 from slipping out of the wires 10. This configuration allows each magnetic material portion 12 to move along the length of each opposing wire 10.

[0017] The component supply device 1 further includes a spacer 13 corresponding to a separation section. The spacer 13 has a plurality of through holes 130 into which each of the plurality of wires 10 is inserted. The plurality of through holes 130 are formed at a predetermined distance interval. Therefore, by inserting each wire 10 into each through hole of the spacer 13, the plurality of wires 10 are arranged at a predetermined distance apart from one another. It is preferable that the predetermined distance interval be greater than the longitudinal length of the component to be supplied.

[0018] The magnetic material portion accommodating portion 20 is a component that accommodates multiple magnetic material portions 12. The magnetic material portion accommodating portion 20 is disposed above the multiple wires 10 and the multiple magnetic material portions 12. FIG. 7 is a perspective view showing the magnetic material portion accommodating portion 20 as viewed from below. The magnetic material portion accommodating portion 20 has an opening that accommodates the multiple wires 10, the multiple magnetic material portions 12, and the spacers 13. The size and shape of the opening are such that the components to be supplied that are attached to the multiple magnetic material portions 12 by magnetic force cannot be accommodated therein. As the multiple wires 10 rise, the multiple magnetic material portions 12 and the spacers 13 rise, and the multiple magnetic material portions 12 and the spacers 13 are accommodated in the magnetic material portion accommodating portion 20. At this time, the components to be supplied that are attached to the multiple magnetic material portions 12 come into contact with the magnetic material portion accommodating portion 20 and fall. In this embodiment, the spacer 13 has a ladder shape, but in other embodiments, various shapes can be adopted as the shape of the spacer 13 as long as the spacer 13 can be accommodated within the magnetic material portion accommodating portion 20.

[0019] The first component receiving section 30 receives the components to be supplied. As shown in FIGS. 3 and 4 , the first component receiving section 30 is disposed below the magnetic material receiving section 20. The first component receiving section 30 can rotate about a vertical axis located at the center of the first component receiving section 30. In this embodiment, the first component receiving section 30 has a bowl shape. However, in other embodiments, the first component receiving section 30 can have any other shape as long as the first component receiving section 30 is rotatable.

[0020] The component transfer unit 40 is a movable component that transfers components to be supplied. The component transfer unit 40 is configured to move in the front-to-rear direction of the component supply device 1 between the magnetic material unit accommodation unit 20 and the first component accommodation unit 30 as the multiple wires 10 are raised and lowered. When the tool 2 is installed, the component transfer unit 40 is located in a front position and in contact with the component transfer unit 42, as shown in Figures 3 and 4, etc. On the other hand, when the tool 2 is removed, the component transfer unit 40 is located in a rear position, as shown in Figures 3 and 4, etc. The component transfer unit 40 has an inclined surface 41 that is inclined toward the front of the component supply device 1. The components to be supplied slide on the inclined surface 41.

[0021] Component transfer section 42 is a fixed component that transfers components to be supplied. Component transfer section 42 is disposed forward and below component transfer section 40. As shown in FIGS. 3 and 4, component transfer section 42 has an inclined surface 43 therein that is inclined toward the front of component supply device 1. It is preferable that inclined surface 43 of component transfer section 42 be disposed so as to be continuous with inclined surface 41 of component transfer section 40 when component transfer section 40 is moved forward.

[0022] The component transfer unit 44 is a fixed component that transfers the components to be supplied. The component transfer unit 44 is disposed forward and below the component transfer unit 42. The component transfer unit 44 has an inclined surface 45 that is inclined toward the front of the component supply device 1.

[0023] The second component storage section 50 stores the components to be supplied that have been transferred by the component transfer sections 40, 42, and 44. The second component storage section 50 is disposed forward and below the component transfer section 44. In this embodiment, the second component storage section 50 is bowl-shaped, but any other shape may be adopted for the second component storage section 50 as long as the worker can easily grasp the components to be supplied.

[0024] The tool setting part 60 is a component for setting a tool 2 to be used by a worker. In this embodiment, the tool setting part 60 has a cylindrical shape, and a part of the tool 2 is inserted into a through-hole thereof to set the tool 2. As shown in FIG. 3 , the tool setting part 60 is fixed to a rod 61 arranged so as to form a predetermined angle with respect to the ground. The rod 61 is supported by a rod support part 62 so as to form a predetermined angle with respect to the ground. The rod 61 is arranged on the rod support part 62 so as to be movable in its longitudinal direction.

[0025] One end of the wire 70 is connected to the lower end of the rod 61. As shown in FIGS. 3 and 4 , the wire 70 extends to the weight 80 via multiple rollers 71 to 75. The weight 80 is connected to the other end of the wire 70. The weight of the weight 80 is set to a weight that, when the tool 2 is not installed, causes the other end of the wire 70 to be pulled by the weight 80, causing the rod 61 to move diagonally upward and the tool installation unit 60 to be located in the upper position, and is smaller than the weight of the tool 2. As a result, when the tool 2 is not installed, the other end of the wire 70 is pulled by the weight 80, causing the rod 61 to move diagonally upward and the tool installation unit 60 to be located in the upper position. On the other hand, when the tool 2 is installed, the weight of the tool 2 pulls one end of the wire 70, causing the rod 61 to move diagonally downward and the tool installation unit 60 to be located in the lower position.

[0026] The wire support part 11 is connected to the connection part 21. The connection part 21 is connected to the lifting part 22. As shown in FIG. 4 , the lifting part 22 has a plurality of rotating parts, and the plurality of rotating parts grip a frame extending in the vertical direction. The lifting part 22 is also connected to the wire 70 extending between the roller 73 and the roller 74. This causes the lifting part 22 to rise and fall in accordance with the movement of the wire 70. As a result, the wire support part 11 rises and falls in accordance with the movement of the wire 70.

[0027] 8 is a diagram showing the rotation mechanism that rotates the first component-receiving unit 30. This diagram shows the rotation mechanism from the rear of the component supply device 1. A plurality of protrusions 31 are arranged radially on the bottom of the first component-receiving unit 30, centering on the rotation axis of the first component-receiving unit 30. This rotation mechanism includes a flap 90, a stop plate 91, and a frame 92.

[0028] The flap 90 is connected to the stop plate 91 by means of a metal shaft 93. The flap 90 can rotate around the longitudinal axis of the metal shaft 93 as a rotation axis. The flap 90 is arranged so as to contact one side of the stop plate 91. Therefore, while the flap 90 is in contact with the stop plate 91, it cannot rotate toward the back side of FIG. 8, i.e., toward the front of the component supply device 1.

[0029] The stopping plate 91 is fixed to a frame 92 that is movable in the front-rear direction of the component supplying device 1. The frame 92 extends in the front-rear direction and is connected to the wire 70 that extends between the rollers 71 and 72. Therefore, as described above, when the wire 70 is pulled, the frame 92 moves in the front-rear direction of the component supplying device 1.

[0030] More specifically, when the tool 2 is installed in the tool installation section 60, the rotation mechanism is disposed at the rear side of FIG. 8, i.e., the front position. On the other hand, when the tool 2 is not installed in the tool installation section 60, the rotation mechanism is disposed at the front side of FIG. 8, i.e., the rear position. Therefore, when the worker removes the tool 2 installed in the tool installation section 60, the rotation mechanism moves from the front position to the rear position. At this time, as shown in the upper part of FIG. 8, the flap 90 comes into contact with the protrusion 31 of the first component storage section 30, causing the first component storage section 30 to rotate. This causes the components to be supplied in the first component storage section 30 to be mixed up.

[0031] On the other hand, when the worker places the tool 2 on the tool placement section 60, the rotation mechanism moves from the rear position to the front position. At this time, as shown in the lower part of Fig. 8 , the flap 90 comes into contact with the protrusion 31 of the first component storage section 30, but the flap 90 does not rotate the first component storage section 30 because it rotates around the longitudinal axis of the shaft metal member 93 as the rotation axis. This makes it possible to suppress wear on the components due to the rotation of the first component storage section 30.

[0032] The component transfer unit 40 is fixed to frames 46 and 47 that are movable in the front-rear direction of the component supply device 1 shown in FIG. 4. These frames 46 and 47 are connected to a frame 92 of the rotation mechanism via frames 48 and 49 shown in FIG. 3, and can be linked to the front-rear movement of the frame 92. When the tool 2 is installed in the tool installation unit 60, the component transfer unit 40 is located in the front position. At this time, the component transfer unit 40 is located directly below the magnetic material unit accommodation unit 20. On the other hand, when the tool 2 is not installed in the tool installation unit 60, the component transfer unit 40 is located in the rear position. At this time, the component transfer unit 40 is not located between the magnetic material unit accommodation unit 20 and the first component accommodation unit 30. This allows the multiple magnetic material units 12 to descend into the first component accommodation unit 30.

[0033] The operation of the component supply device 1 will now be described. First, when the worker removes the tool 2 from the tool installation section 60, the weight 80 descends, pulling the wire 70, and the wire support section 11 and the plurality of wires 10 descend. At this time, the rotation mechanism moves from the front position to the rear position and rotates the first component storage section 30. As the plurality of wires 10 descend, the plurality of magnetic material sections 12 attached to the lower ends of the plurality of wires 10 descend into the first component storage section 30 and come into contact with the components to be supplied. At this time, the components to be supplied are attached to each of the plurality of magnetic material sections 12 by the magnetic force of the plurality of magnetic material sections 12.

[0034] Next, when the worker installs the tool 2 in the tool installation section 60, the rod 61 moves diagonally downward, pulling the wire 70 and raising the wire support section 11 and the plurality of wires 10. The plurality of magnetic material sections 12 also rise as the plurality of wires 10 rise and are housed in the magnetic material section housing section 20. At this time, the plurality of components to be supplied that have come into contact with the plurality of magnetic material sections 12 and are attached by magnetic force come into contact with the magnetic material section housing section 20 and fall as the plurality of magnetic material sections 12 are housed in the magnetic material section housing section 20. As described above, when the tool 2 is installed in the tool installation section 60, the component transfer section 40 is located directly below the magnetic material section housing section 20, and therefore the plurality of components to be supplied that have fallen from the plurality of magnetic material sections 12 fall onto the component transfer section 40. The plurality of components to be supplied that have fallen onto the component transfer section 40 slide down the inclined surfaces of the component transfer sections 40, 42, and 44 and are housed in the second component housing section 50. By adopting this configuration, the component supply device 1 can supply a plurality of components simultaneously.

[0035] As described above, the component supply device 1 also includes a spacer 13 that spaces the lower ends of the wires 10 apart from one another. The spacer 13 has a plurality of through holes into which the wires 10 are inserted. The through holes are spaced apart at a predetermined distance. By adopting this configuration, the magnetic material portions 12 attached to the lower ends of the wires 10 can be spaced apart from one another at a predetermined distance. This allows the spacing between adjacent magnetic material portions 12 to be maintained at the predetermined distance. Therefore, by making the predetermined distance longer than the longitudinal length of the component to be supplied, it is possible to prevent one component to be supplied from adhering to multiple magnetic material portions 12.

[0036] As described above, the magnetic material parts 12 each have a through hole into which one of the wires 10 is inserted. Each of the magnetic material parts 12 is movable along the length of the wire inserted in the through hole. This configuration makes it easier for the magnetic material parts 12 to come into contact with the components to be supplied when they are lowered into the first component-receiving part 30, thereby increasing the probability that the components to be supplied will adhere to the magnetic material parts 12.

[0037] Furthermore, as described above, the first component-receiving section 30 is configured to rotate in conjunction with the descent of the multiple wires. By adopting this configuration, the components to be supplied in the first component-receiving section 30 are mixed up, reducing uneven distribution of the components. Therefore, when the magnetic material section 12 is lowered into the first component-receiving section 30, the probability that the components to be supplied will adhere to the magnetic material section 12 can be increased.

[0038] Furthermore, as described above, the component transfer units 40, 42, and 44 have inclined surfaces 41, 43, and 45. The components to be supplied that have fallen onto the component transfer unit 40 slide along the inclined surfaces 41, 43, and 45 of the component transfer units 40, 42, and 44 and are transferred to the second component storage unit 50. By adopting this configuration, the lengths of the component transfer units 40, 42, and 44 can be designed according to the location where the component supply device 1 is installed. In other words, the position of the second component storage unit 50 can be flexibly determined according to the location where the component supply device 1 is installed. This increases the flexibility of the installation location of the component supply device 1. For example, the second component storage unit 50 can be located near the worker's work position, and the main body of the component supply device 1 can be installed away from the worker.

[0039] The component supply device 1 further includes gears 100 and 101 and an engaging portion 102. The gears 100 and 101 are gears that limit the rotation speed in one rotation direction and do not limit the rotation speed in the other rotation direction. The gears 100 and 101 limit the rotation speed in different rotation directions, respectively.

[0040] The engaging portion 102 is a component that engages with the gears 100 and 101. The engaging portion 102 is connected to the wire 70 that extends between the roller 73 and the roller 74, and moves up and down in accordance with the movement of the wire 70.

[0041] As shown in Figures 1A and 2, when the tool 2 is installed on the tool installation part 60, the engagement part 102 is located in an upper position and engages with the gear 100. On the other hand, as shown in Figures 1B and 2, when the tool 2 is not installed on the tool installation part 60, the engagement part 102 is located in a lower position and engages with the gear 101. The gear 100 limits the rotational speed of the gear 100 so as to suppress the descending speed of the engagement part 102. On the other hand, the gear 101 limits the rotational speed of the gear 101 so as to suppress the ascending speed of the engagement part 102.

[0042] By adopting this configuration, it is possible to suppress sudden movement of the wire 70 that occurs when the tool 2 is removed or installed. For example, even if an operator roughly removes the tool 2 from the tool installation section 60, sudden movement of the wire 70 is suppressed. Furthermore, even if an operator roughly installs the tool 2 on the tool installation section 60, sudden movement of the wire 70 is suppressed. This is particularly advantageous because, when the operator roughly installs the tool 2 on the tool installation section 60, it is possible to suppress the components to be supplied that have been attached by magnetic force to the magnetic material section 12 from falling off before the magnetic material section 12 is accommodated in the magnetic material section accommodation section 20.
