[Technical Field]

[0001] The present invention relates to a component supply device. [Background technology]

[0002] When workers manually pick up parts from a shelf that has multiple part placement sections, each containing multiple different types of parts, to assemble a product, it is important to prevent parts from being mixed up. Patent Document 1 proposes a production navigation system that projects an arrow and the number of parts to be used onto the part placement section corresponding to the part to be removed from a projector, allowing the worker to visually identify the part placement section corresponding to the part to be removed and instructing the worker on the number of parts to be removed.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-45669 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, a computer is required to control the display of arrows and the number of parts by the projector, and a complex control program is required to make the computer function, making the system complex and large-scale, and resulting in high equipment costs. On the other hand, when performing work such as supplying a plurality of first parts and a plurality of second parts to predetermined jig locations, applying the above-mentioned conventional technology to prevent part mix-up (mis-picking) is not realistic because it would make the system too complex and increase the equipment costs, and some kind of improvement is required. The present invention has been made in view of the above circumstances, and its object is to provide a parts supply device that has a simple configuration that reliably prevents parts from being mixed up, enables parts to be supplied reliably and efficiently, and is advantageous in terms of reducing costs. [Means for solving the problem]

In addition, one embodiment of the present invention is characterized in that the cover member has a front plate portion hanging downward from the front end of the first cover portion located opposite the exposure opening, a rear plate portion hanging downward from the rear end of the second cover portion located opposite the exposure opening, and a bottom plate portion connecting the lower end of the front plate portion and the lower end of the rear plate portion, and is formed open in the left-right direction, and the transport path extends in the left-right direction through a space surrounded by the first cover portion, the front plate portion, the second cover portion, and the rear plate portion on the bottom plate portion. In one embodiment of the present invention, the front plate portion is provided with a handle for moving the cover member in the front-rear direction. In one embodiment of the present invention, the first component placement member and the second component placement member are connected to each other so as to be able to move integrally, the first component placement member and the second component placement member are transported on the transport path in a transport direction that is one of the left and right directions, and the first cover portion and the second cover portion are provided with stoppers that can come into contact with an end of the first component placement member or an end of the second component placement member that is downstream in the transport direction at the first position and the second position. In addition, one embodiment of the present invention is characterized in that the part supply device has a frame, and when an operator stands in front of the conveying path, the direction toward the operator in the fore-and-aft direction is defined as the front, and the direction away from the operator is defined as the rear, the interlocking mechanism has a fore-and-aft moving member supported by the frame behind the cover member and supported so as to be movable in the fore-and-aft direction, the cover member is connected to the fore-and-aft moving member, and the cover member and the fore-and-aft moving member move together in the fore-and-aft direction. In addition, one embodiment of the present invention is characterized in that the frame is provided with a first stopper that abuts against the forward / backward moving member to determine a first position of the cover member, and a second stopper that determines a second position of the cover member. [Effects of the Invention]

[0006] According to one embodiment of the present invention, the first component and the second component can be accommodated in the first component placement member and the second component placement member with a simple configuration, which is advantageous in terms of reliably and efficiently supplying the first component and the second component. Furthermore, since an expensive computer for performing complex control, as in the prior art, is not required, this is advantageous in terms of reducing the cost of the component supply device. Furthermore, if the cover member has a front plate portion, a rear plate portion, and a bottom plate portion and is formed open in the left-right direction, and the conveying path extends left-right through the space on the bottom plate portion surrounded by the first cover portion, the front plate portion, the second cover portion, and the rear plate portion, the cover member can be easily constructed, which is advantageous in reducing the cost of the component supply device. Furthermore, if a handle is provided on the front panel portion for moving the cover member in the forward and backward directions, the cover member can be moved easily and reliably, which is advantageous in facilitating operation of the component supply device. Furthermore, the first and second component placement members are connected so as to be able to move together, and the first and second component placement members are transported on the transport path in a transport direction that is one of the left and right directions. If the first and second cover parts are provided with stoppers that can come into contact with the end of the first or second component placement member on the downstream side in the transport direction at the first and second positions, after the first and second components have been placed in the first and second component placement members, the transport jig cannot be moved downstream in the transport direction unless the cover members are positioned in the third position and a visual check is made. This prevents workers from forgetting to visually check, which is advantageous in reducing work errors. Furthermore, when an operator stands in front of the conveying path, the direction toward the operator in the front-to-back direction is defined as the front, and the direction away from the operator is defined as the rear. If the interlocking mechanism is configured to include a front-to-rear moving member that is supported by a frame behind the cover member and is supported so as to be movable in the front-to-rear direction, and the cover member is connected to the front-to-rear moving member so that the cover member and the front-to-rear moving member move together in the front-to-rear direction, the interlocking mechanism can be easily configured, which is advantageous in reducing the cost of the component supply device. Furthermore, if the frame is provided with a first stopper that abuts against the forward / backward moving member to determine the first position of the cover member, and a second stopper that determines the second position of the cover member, the positioning of the cover member can be performed easily and reliably, which is advantageous in facilitating the operation of the component supply device.

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The parts supply device of this embodiment supplies a plurality of intake valve stem seals and a plurality of exhaust valve stem seals so that the intake valve stem seals can be pressed into the valve stems of the intake valves of an engine by a work robot of an automatic press-fitting machine, and the exhaust valve stem seals can be pressed into the valve stems of the exhaust valves. In this embodiment, the first component 24 (FIG. 3) is an intake valve stem seal, and the second component 26 (FIG. 5) is an exhaust valve stem seal.

[0009] As shown in Figures 1, 2(A), and (B), the component supply device 10 includes a conveying path 12, a conveying jig 14, a first storage box 16, a second storage box 18, a cover member 20, and a linkage mechanism 22. In the following drawings, the symbol FC indicates the conveying direction, the symbol UP indicates the upward direction, the symbol FR indicates the forward direction, and the symbol BK indicates the backward direction. The conveying path 12 is formed by a roller conveyor. The conveying path 12 extends horizontally in the left-right direction. In this left-right direction, the direction away from the first storage box 16, the second storage box 18, the cover member 20, and the interlocking mechanism 22 is the conveying direction FC. Furthermore, when a worker stands in front of the conveying path 12, the horizontal direction moving away from and towards the worker is the front-to-back direction, and the direction toward the worker in the front-to-back direction is the front FR, and the direction moving away from the worker is the rear BK, and the conveying direction FC and the front-to-back direction are perpendicular to each other. The transport jig 14 is disposed on the transport path 12 . Transport jig 14 is composed of first and second component placement members 14A and 14B that extend in transport direction FC and are spaced apart in the front-to-rear direction, and a pair of connecting members 14C that connect first and second component placement members 14A and 14B.

The first component placement member 14A and the second component placement member 14B are provided with a plurality of first component placement recesses 1402A and a plurality of second component placement recesses 1402B spaced apart in the longitudinal direction thereof. In component supply device 10, after first components 24 are accommodated in all first-component placement recesses 1402A and second components 26 are accommodated in all second-component placement recesses 1402B, transport jigs 14 are moved by an operator on a roller conveyor toward the automatic press-fitting machine. The first components 24 and second components 26 are transported to the automatic press-fitting machine by arranging multiple transport jigs 14 on the roller conveyor in this manner, and are then removed from transport jigs 14 by a work robot of the automatic press-fitting machine and automatically press-fitted into the valve stems of the intake valves and the exhaust valves, respectively, of the engine. In other words, first components 24 and second components 26 are assembled into the engine by the press-fitting equipment.

[0010] As shown in Figures 1, 3, and 5, the component supply device 10 is provided with a first storage box 16 located at the rear BK of the conveying path 12 and above the first component placement member 14A UP, the first storage box 16 having a first opening 16B that stores multiple first components 24 and is opened and closed by a first lid 16A. In addition, the component supply device 10 is provided with a second storage box 18 at the rear BK of the conveying path 12 and above the second component placement member 14B UP, which has a second opening 18B that stores multiple second components 26 and is opened and closed by a second lid 18A. The first storage box 16 and the second storage box 18 are arranged side by side in the left-right direction. As shown in Figures 2(A) and (B), a lid roller 28 having an axis parallel to the conveying direction FC is rotatably arranged at the rear end of the first storage box 16 and the second storage box 18.

[0011] As shown in FIGS. 1, 2(A) and 2(B), the cover member 20 is provided in an open state in the conveying direction FC, and the conveying path 12 is located inside the cover member 20. The cover member 20 has a first cover portion 20A that can cover the upper side UP of the first component placement member 14A placed on the conveying path 12, a second cover portion 20B that can cover the upper side UP of the second component placement member 14B, and an exposure opening 20C that is provided between the first cover portion 20A and the second cover portion 20B and can expose both the first component placement member 14A and the second component placement member 14B to the upper side UP. 1, 2(A), and 2(B), the first cover portion 20A is provided horizontally on the upper end of the front plate portion 2002. The second cover portion 20B is provided horizontally on the upper end of the rear plate portion 2004, and the lower end of the front plate portion 2002 and the middle portion between the top and bottom of the rear plate portion 2004 are connected by a bottom plate portion 2006. As shown in FIG. 1, the transport jig 14 is placed on the transport path 12 so that the center of the cover member 20 in the longitudinal direction and the center of the transport jig 14 in the longitudinal direction coincide with each other. As shown in FIGS. 1 and 2(B), the front plate portion 2002 is provided with a handle 30 for moving the cover member 20 back and forth.

[0012] 3, the upper side UP of the second component placement member 14B is covered by the second cover portion 20B at the first position P1 of the cover member 20 in the front-rear direction. The upper side UP of the first component placement member 14A is exposed from the exposure opening 20C at the first position P1 of the cover member 20 in the front-rear direction. 5, the upper side UP of the first component placement member 14A is covered by the first cover portion 20A at the second position P2 of the cover member 20 in the front-rear direction. The upper side UP of the second component placement member 14B is exposed from the exposure opening 20C at the second position P2 of the cover member 20 in the front-rear direction. As shown in FIG. 1, both the first component placement member 14A and the second component placement member 14B are exposed upward UP from the exposure opening 20C at a third position P3 of the cover member 20 in the front-rear direction.

[0013] As shown in FIGS. 3 and 5, the cover member 20 is provided with a stopper 2010 that can abut against the end of the transport jig 14 on the downstream side in the transport direction FC at the first position P1 and the second position P2. 3, the cover member 20 is provided with a stopper 2010 on the second cover portion 20B, which is capable of abutting against an end portion of the second component placement member 14B on the downstream side in the conveying direction FC at the first position P1. Also, as shown in FIG. 5, the cover member 20 is provided with a stopper 2010 on the first cover portion 20A, which is capable of abutting against an end portion of the first component placement member 14A on the downstream side in the conveying direction FC at the second position P2.

[0014] As shown in Figures 4(A) and (B), the interlocking mechanism 22 is connected to the first lid body 16A, the second lid body 18A, and the cover member 20, and is configured so that when the cover member 20 is in a first position P1, the second lid body 18A closes the second opening 18B and the first lid body 16A opens the first opening 16B. As shown in Figures 6(A) and (B), the interlocking mechanism 22 is configured so that when the cover member 20 is in a second position P2, the first lid body 16A closes the first opening 16B and the second lid body 18A opens the second opening 18B. As shown in Figures 2(A) and (B), the interlocking mechanism 22 is configured so that when the cover member 20 is in a third position P3, the first lid body 16A closes the first opening 16B and the second lid body 18A closes the second opening 18B. Various conventionally known mechanisms such as a gear mechanism using gears and racks, a link mechanism, a slider crank mechanism, etc. can be used as the interlocking mechanism 22. In this embodiment, as shown in Figures 2(A) and 2(B), a cam mechanism is used that includes a first cam 32, a second cam 34, and a first rod 36 and a second rod 38 that move up and down in conjunction with the first cam 32 and the second cam 34.

[0015] As shown in Figures 1, 2(A), 3, 4(A), 5, and 6(A), when viewed in a plan view, i.e., when the component supply device 10 is viewed from above, the first cam 32 is composed of a first cam plate 32A that extends in the front-to-rear direction through the center of the width of the first storage box 16 and extends from below the first storage box 16 to the cover member 20, and a first cam surface 32B formed on the upper surface of the first cam plate 32A. The front end of the first cam 32 is connected to the lower half of the rear plate portion 2004 of the second cover portion 20B. The lower portion of the first cam plate 32A is supported by a linear slider (not shown) provided on the frame 40 of the component supply device 10 so as to be movable in the front-rear direction.

[0016] As shown in Figures 1, 2(B), 3, 4(B), 5, and 6(B), when viewed in a plan view, i.e., when the component supply device 10 is viewed from above, the second cam 34 is composed of a second cam plate 34A that extends in the front-to-rear direction through the center of the width of the second storage box 18 and extends from below the second storage box 18 to the cover member 20, and a second cam surface 34B formed on the upper surface of the second cam plate 34A. The front end of the second cam 34 is connected to the lower half of the rear plate portion 2004 of the second cover portion 20B. The lower portion of the second cam plate 34A is supported by a linear slider (not shown) provided on the frame 40 of the component supply device 10 so as to be movable in the front-rear direction.

[0017] 2(A), 4(A), and 6(A), the front portion of first cam surface 32B is formed as first opening-closing cam surface 3202. The rear portion of first cam surface 32B is formed as first opening-opening cam surface 3204. Furthermore, the middle portion in the extension direction of first cam surface 32B is formed as inclined surface 3206 that connects first opening-closing cam surface 3202 and first opening-opening cam surface 3204. 2(B), 4(B), and 6(B), the front portion of second cam surface 34B is formed as second-opening-opening cam surface 3402. The rear portion of second cam surface 34B is formed as second-opening-closing cam surface 3404. Furthermore, the middle portion of second cam surface 34B in the extension direction is formed as inclined surface 3406 that connects second-opening-opening cam surface 3402 and second-opening-closing cam surface 3404.

[0018] As shown in Figure 2(A), a first rod 36 extends vertically above the first cam surface 32B UP at the rear BK of the first storage box 16 and is arranged so as to be movable vertically by a bearing 36A provided on the frame 40. A first roller 36B that rolls on the first cam surface 32B is rotatably provided at the lower end of the first rod 36. A first lid body 16A is swingably provided at the upper end of the first rod 36. Furthermore, the first lid body 16A is biased by a torsion coil spring (not shown) in a direction that closes the first opening 16B. 2(A) and 6(A), first lid body 16A contacts lid body roller 28 to close first opening 16B with first roller 36B positioned on first opening-closing cam surface 3202. As shown in FIG. 4(A), first lid body 16A contacts lid body roller 28 to open first opening 16B with first roller 36B positioned on first-opening-opening cam surface 3204.

[0019] As shown in Figure 2(B), a second rod 38 extending vertically above the second cam surface 34B at the rear BK of the second storage box 18 is arranged so as to be movable vertically by a bearing 38A provided on a frame 40 (not shown). A second roller 38B that rolls on a second cam surface 34B is rotatably provided at the lower end of the second rod 38. A second lid 18A is swingably provided at the upper end of the second rod 38. Furthermore, the second lid 18A is biased by a torsion coil spring (not shown) in a direction that closes the second opening 18B. 2(B) and 4(B), second lid body 18A contacts lid body roller 28 to close second opening 18B with second roller 38B positioned on second-opening-closing cam surface 3404. As shown in FIG. 6(B), second lid body 18A contacts lid body roller 28 to open second opening 18B with second roller 38B positioned on second-opening-opening cam surface 3402.

[0020] The first cam plate 32A and the second cam plate 34A constitute a front-rear moving member that is supported by a frame 40 and is movable in the front-rear direction. The cover member 20 is connected to the front-rear moving member, and the cover member 20 and the front-rear moving member move together in the front-rear direction. In this embodiment, a cam mechanism including first cam plate 32A and second cam plate 34A is used, and therefore first cam plate 32A and second cam plate 34A constitute a front-rear moving member. On the other hand, even when a mechanism other than a cam mechanism, such as a gear mechanism, link mechanism, or slider crank mechanism, is used as interlocking mechanism 22, providing a front-rear moving member is advantageous in terms of smooth front-rear movement of cover member 20. As shown in Figures 4(A) and (B), a frame 40 (not shown) of the component supply device 10 is provided with a first stopper 42 that abuts against the forward / backward moving members (first cam plate 32A and second cam plate 34A) to determine a first position P1 of the cover member 20, and a second stopper 44 that abuts against the forward / backward moving members (first cam plate 32A and second cam plate 34A) to determine a second position P2 of the cover member 20.

[0021] Next, a method of using the component supply device 10 will be described. As shown in Figures 1, 2(A), and (B), the worker positions the cover member 20 at the third position P3 and places the transport jig 14 on the transport path 12 so that the longitudinal center of the cover member 20 coincides with the longitudinal center of the transport jig 14. When the cover member 20 is located at the third position P3, the interlocking mechanism 22 causes the first lid body 16A to close the first opening 16B, and the second lid body 18A to close the second opening 18B.

[0022] Next, the worker grasps the handle 30 of the cover member 20 and pulls it forward FR, moving the cover member 20 from the third position P3 toward the first position P1. As a result, as shown in Figures 3, 4(A), and 4(B), the front-rear moving members (the first cam plate 32A and the second cam plate 34A) come into contact with the first stopper 42, and the cover member 20 is positioned at the first position P1. When cover member 20 moves to first position P1, second cover portion 20B covers second component placement member 14B on the upper side UP. This also exposes first component placement member 14A on the upper side UP through exposure opening 20C. Furthermore, second opening 18B is closed by second lid body 18A via interlocking mechanism 22, and first opening 16B is opened by first lid body 16A via interlocking mechanism 22. Therefore, the worker removes the first component 24 stored in the first storage box 16 with the first opening 16B open, and stores the first component 24 in the first component placement recess 1402A of the first component placement member 14A exposed upward UP through the exposure opening 20C. At this time, second opening 18B of second storage box 18 is closed by second lid 18A, which reliably prevents the worker from accidentally removing second component 26. Furthermore, upper side UP of second component placement member 14B is covered by second cover portion 20B, which reliably prevents the worker from accidentally placing first component 24 in second component placement recess 1402B.

[0023] Once the first components 24 have been placed in all of the first component placement recesses 1402A, the worker grasps the handle 30 of the cover member 20 and pushes it rearward BK to move the cover member 20 from the first position P1 toward the second position P2. As a result, as shown in Figures 5, 6(A), and 6(B), the front-rear moving members (the first cam plate 32A and the second cam plate 34A) come into contact with the second stopper 44, and the cover member 20 is positioned at the second position P2. When cover member 20 is located at second position P2, first cover portion 20A covers the upper side UP of first component placement member 14A. This also exposes second component placement member 14B to the upper side UP through exposure opening 20C. Furthermore, interlocking mechanism 22 causes cover member 20 to close first opening 16B with first lid body 16A and open second opening 18B with second lid body 18A. Therefore, the worker removes the second component 26 stored in the second storage box 18 with the second opening 18B open, and stores the second component 26 in the second component placement recess 1402B of the second component placement member 14B exposed upward UP through the exposure opening 20C. At this time, first opening 16B of first housing box 16 is closed by first lid 16A, which reliably prevents the worker from accidentally removing first component 24. Furthermore, the upper side UP of first component placement member 14A is covered by first cover portion 20A. This reliably prevents the worker from accidentally placing second component 26 in first component placement recess 1402A.

[0024] Once all of the second component placement recesses 1402B have been filled with the second components 26, the worker grasps the handle 30 of the cover member 20 and pulls it forward FR to move the cover member 20 from the second position P2 to the third position P3. 1, 2(A), and 2(B), when cover member 20 is located at third position P3, both first component placement member 14A and second component placement member 14B are exposed upward UP through exposure opening 20C. This allows an operator to visually check whether first component 24 and second component 26 are housed in first component placement member 14A and second component placement member 14B, respectively, without any missing components.

[0025] If no problems are found upon visual inspection, the worker manually pushes the transport jig 14 downstream in the transport direction FC, transports the transport jig 14 from the component supply device 10 toward the automatic press-fitting machine, and supplies the first component 24 and the second component 26 to the automatic press-fitting machine. If visual inspection reveals that the first component 24 or the second component 26 has not been accommodated, the worker can simply position the cover member 20 at the first position P1 or the second position P2 and perform the accommodation work for the first component 24 or the second component 26. In this manner, the component supply device 10 supplies the first component 24 and the second component 26 to the automatic press-fitting machine.

[0026] According to this embodiment, at a first position P1 of the cover member 20 in the front-rear direction, the upper side UP of the second component placement member 14B is covered by the second cover portion 20B, and the first component placement member 14A is exposed to the upper side UP through the exposure opening 20C. At a second position P2 of the cover member 20 in the front-rear direction, the upper side UP of the first component placement member 14A is covered by the first cover portion 20A, and the second component placement member 14B is exposed to the upper side UP through the exposure opening 20C. At a third position P3 of the cover member 20 in the front-rear direction, both the first component placement member 14A and the second component placement member 14B are exposed to the upper side UP through the exposure opening 20C. Then, by the interlocking mechanism 22, when the cover member 20 is at a first position P1, the first opening 16B is opened by the first lid body 16A and the second opening 18B is closed by the second lid body 18A, when the cover member 20 is at a second position P2, the second opening 18B is opened by the second lid body 18A and the first opening 16B is closed by the first lid body 16A, and when the cover member 20 is at a third position P3, the first opening 16B is closed by the first lid body 16A and the second opening 18B is closed by the second lid body 18A. Therefore, with a simple configuration, component supply device 10 can reliably prevent a worker from confusing first component 24 and second component 26. Therefore, component supply device 10 can reliably prevent erroneous assembly of first component 24 and second component 26 into an engine in press-fitting equipment. Furthermore, component supply device 10 allows the operator to reliably place first component 24 and second component 26 in first component placement member 14A and second component placement member 14. This is advantageous in reliably and efficiently supplying first component 24 and second component 26 to the automatic press-fitting machine. Furthermore, since there is no need for an expensive computer for performing complex control as in the prior art, this is advantageous in terms of reducing the cost of the component supply device 10.

[0027] In this embodiment, the cover member 20 has a front plate portion 2002, a rear plate portion 2004, and a bottom plate portion 2006 and is formed to be open in the left-right direction. The transport path 12 extends in the left-right direction on the bottom plate portion 2006 in a space surrounded by the first cover portion 20A, the front plate portion 2002, the second cover portion 20B, and the rear plate portion 2004. Therefore, the cover member 20 can be easily configured, which is advantageous in reducing the cost of the component supply device 10.

[0028] In addition, in this embodiment, a handle 30 is provided on the front plate portion 2002 for moving the cover member 20 in the forward and backward directions, so that the cover member 20 can be moved easily and reliably, which is advantageous in facilitating the operation of the component supply device 10.

[0029] In this embodiment, the first component placement member 14A and the second component placement member 14B are connected so as to be able to move integrally, and the first component placement member 14A and the second component placement member 14B are transported on the transport path 12 in a transport direction FC, which is one of the left and right directions. At the first position P1 and the second position P2, the first cover portion 20A and the second cover portion 20B are provided with stoppers 2010 that can come into contact with the end of the first component placement member 14A or the end of the second component placement member 14B on the downstream side of the transport direction FC. Therefore, at the first position P1 and the second position P2 of the cover member 20, movement of the transport jig 14 downstream in the transport direction FC is prohibited, and movement of the transport jig 14 downstream in the transport direction FC is permitted only at the third position P3 of the cover member 20. Therefore, after the first component 24 and the second component 26 are accommodated in the first component placement member 14A and the second component placement member 14B, the transport jig 14 cannot be moved downstream in the transport direction FC unless the cover member 20 is positioned at the third position P3 and a visual check is performed. This prevents the worker from forgetting to perform a visual check, which is advantageous in reducing work errors.

[0030] Furthermore, in this embodiment, when an operator stands in front of the conveying path 12, the direction toward the operator in the front-to-back direction is defined as the front FR, and the direction away from the operator is defined as the rear BK. The interlocking mechanism 22 is configured to include a front-to-rear moving member (first cam plate 32A and second cam plate 34A) supported by a frame 40 at the rear BK of the cover member 20 so as to be movable in the front-to-rear direction, and the cover member 20 is connected to the front-to-rear moving member so that the cover member 20 and the front-to-rear moving member move together in the front-to-rear direction. Therefore, the interlocking mechanism 22 can be configured simply, which is advantageous in reducing the cost of the component supply device 10.

[0031] In addition, in this embodiment, the frame 40 is provided with a first stopper 42 that abuts against the forward / backward moving members (first cam plate 32A and second cam plate 34A) and determines the first position P1 of the cover member 20, and a second stopper 44 that determines the second position P2 of the cover member 20. Therefore, the positioning of the cover member 20 can be performed simply and reliably, which is advantageous in facilitating the operation of the component supply device 10.
