Description

  The present invention relates to a component supply system.

  For example, in a vehicle such as an automobile, there is one in which a front portion of a vehicle interior is configured by a cockpit module. In this cockpit module, parts constituting the cockpit are assembled and integrated in advance, and can be mounted on the vehicle body at a time. Thus, by making a cockpit into a module and making it a cockpit module, it becomes possible to manufacture a vehicle in a shorter time than before, and to reduce the manufacturing cost of the vehicle.

  The cockpit module is manufactured by a dedicated product assembly facility. This product assembly facility moves the product assembly cart along the assembly line (cockpit module assembly line) and installs parts in order at a plurality of work stages provided in the middle of the assembly line. The cockpit module is assembled on the carriage.

  In such a product assembly facility, a component supply system using a component transport cart that can transport components to a plurality of work stages is employed (see, for example, Patent Document 1). The component supply system disclosed in Patent Document 1 uses a component conveying cart having a shelf-like component storage unit at the bottom and a component mounting table that is larger and flatter than the component storage unit at the top of the component storage unit. ing.

Japanese Patent Laid-Open No. 06-143069

  However, in the component transport cart described in Patent Document 1, the component storage unit and the component mounting table are simply shelves or flat platforms, so that the component mounting position is not particularly fixed, and the components are always fixed. It did not have the function to arrange and arrange in order of work stage. Therefore, it was not possible to efficiently remove the parts from the parts transport cart at each work stage. In addition, since the parts mounting table is a flat table, the parts can only be placed sideways, and a large area is required for the parts mounting table, and large parts and long parts must be mounted efficiently. I could not.

  Accordingly, the main object of the present invention is to solve the above-described problems.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
1 to 9 are for explaining this embodiment.

  <Configuration> The configuration of this embodiment will be described below.

  For example, there are vehicles such as automobiles in which a front portion of a vehicle interior is configured by a cockpit module. In this cockpit module, parts constituting the cockpit are assembled and integrated in advance, and can be mounted on the vehicle body at a time. Thus, by making a cockpit into a module and making it a cockpit module, it becomes possible to manufacture a vehicle in a shorter time than before, and to reduce the manufacturing cost of the vehicle.

  The cockpit module is manufactured by a dedicated product assembly facility. This product assembly facility moves the product assembly cart along the assembly line (cockpit module assembly line) and installs parts in order at a plurality of work stages provided in the middle of the assembly line. The cockpit module is assembled on the carriage.

  Here, the product assembly facility is as shown in FIG. That is, with respect to the product assembly cart 2 that moves along the assembly line 1, the product 3 such as the cockpit module is transferred to the air conditioning unit 5 (see FIG. 3) or the vehicle body strength member 6 ( 3) is attached, the main harness is attached at the second work stage 4 (b), the air conditioning duct 7 (see FIG. 4) is attached at the third work stage 4 (c), and the fourth By attaching the instrument panel 8 (see FIG. 5) and the like at the work stage 4 (d), the basic shape of the cockpit module can be formed. Thereafter, parts that are attached from the outside, small parts, finishing parts, and other parts are sequentially attached to each work stage 4 that follows the cockpit module having the basic shape. The cockpit module as the product 3 is completed. For example, in the fifth work stage 4 (e), a steering column is attached. The product assembly facility may assemble products other than the cockpit module.

  The following parts supply system is adopted for such a product assembly facility. This component supply system uses a component conveyance carriage 12 including a carriage main body 11 that can convey components to a plurality of work stages 4.

As shown in FIG. 2 (FIG. 6 to FIG. 6), the parts transport cart 12 is attached with a travel drive device 21 (see FIG. 3) capable of self-propelling the cart body 11 with respect to the cart body 11 on which components can be mounted. It is said that
The bogie main body 11 has a low profile mounting portion 23 with a low height on one side and a high profile mounting portion 24 with a taller height than the low profile mounting portion 23 on the other side. It is said that.
The traveling drive device 21 is attached to the low-profile mounting portion 23 side.
A balance weight 25 capable of preventing the traveling drive device 21 from being lifted by an inclination toward the other side of the high-profile mounting portion 24 is installed on the low-profile mounting portion 23.

  Here, there are a plurality of types of components that are the main components of the cockpit module, such as the air conditioning unit 5, the vehicle body strength member 6, the main harness, the air conditioning duct 7, and the instrument panel 8. It is a large-sized part.

  The cart body 11 is constituted by, for example, a shelf-shaped component mounting portion 22 using a metal rod-shaped structural material, and a traveling wheel 26 (driven wheel) such as a free caster is provided below the cart body 11. Is installed. The component mounting unit 22 can mount a plurality of types of components in the order of the work stage 4. The component mounting portion 22 is provided with the low-profile mounting portion 23 and the high-profile mounting portion 24 described above. However, the structure of the cart body 11 is not limited to the above.

  The traveling drive device 21 is a self-propelled unit that integrally includes a motor, drive wheels, a control device, and the like. The battery may be built in the self-running unit, provided outside the self-running unit, or may be used in combination with an external battery.

  In order to be able to follow the unevenness of the road surface, the travel drive device 21 swings in the vertical direction with respect to the carriage main body 11 via an attachment shaft portion 27 (see FIG. 3) extending in the width direction (of the carriage main body 11). It is connected and pivotally supported so that it can move or tilt. The attachment by the attachment shaft portion 27 is detachable.

  A guide portion 28 (see FIG. 1) such as a rail or a travel guide is attached to the road surface on which the carriage body 11 travels, and the travel drive device 21 travels along the guide portion 28. . Alternatively, instead of providing the guide unit 28, the travel drive device 21 may self-travel along a previously taught route. Furthermore, the traveling drive device 21 may be configured by individually attaching parts such as a motor, a drive wheel, a control device, and a battery to the carriage main body 11 instead of being a self-propelled unit.

  The low-profile mounting portion 23 is a shelf-like one. The low-profile mounting portion 23 has, for example, a plurality of shelf levels 29a and 29b (see FIG. 3) such as an upper level and a middle level. The travel drive device 21 and the balance weight 25 (at least a part thereof) and the like are installed on the lower side of the middle shelf 29b and the like.

  In addition, the high-profile mounting portion 24 has a frame shape that defines a larger storage space or the like than the low-profile mounting portion 23. The cart body 11 is preferably traveled such that the low-profile mounting portion 23 side is the front side and the high-profile mounting portion 24 side is the rear side.

  The high-profile mounting unit 24 includes a long component holding unit 32 that can mount the long component 31 in a vertically oriented state.

  Here, since the cockpit module has substantially the same size (approximately 1.5 m to 2 m) as the width of the vehicle, the vehicle body strength member 6, the air conditioning duct 7, and the instrument panel 8 described above have a width of the vehicle. The long component 31 is approximately the same size as the dimension. The main harness described above also has the same long component 31, but the main harness is thinner than the other long components 31 and has low shape retention and can be deformed. I have to. However, the main harness may be handled together with the other long component 31.

  The vertically oriented state means that the longitudinal direction of the long component 31 is substantially directed in the vertical direction. On the other hand, the sideways state means that the longitudinal direction of the long component 31 is directed substantially in the horizontal direction.

  The long component holder 32 has a height and shape suitable for holding the vehicle body strength member 6, the air conditioning duct 7, and the instrument panel 8 in a vertical orientation. In this case, the tall mounting portion 24 is taller than the long component holding portion 32, and the vehicle body strength member 6 is hooked on the high mounting portion 24 as the long component holding portion 32. The strength member hooking portion 33 (see FIG. 3) for holding, the duct hooking portion 34 (see FIG. 4) for hooking and holding the air conditioning duct 7 and the instrument panel 8 are hooked. Arm portions and hook portions such as an instrument panel hooking portion 35 (see FIG. 5) are provided so that they can be held. At this time, it is preferable that the plurality of long component holders 32 be installed so as to hold a plurality of types of long components 31 in a vertically oriented state in the order of the work stage 4.

  The vehicle body strength member 6 described above is a metal beam member that connects the left and right vehicle body panels, and is the longest component 31 having the largest weight among the above. The air-conditioning duct 7 is a resin tubular member, and is the longest component 31 that is lightest and lightest among the above. In this case, the long part 31 is obtained by connecting and integrating the left and right side ventilator ducts. The air conditioning duct 7 is attached from above the vehicle body strength member 6 and the main harness.

  The instrument panel 8 is a resin surface panel, and is the longest part 31 having the largest and middle weight among the above. The instrument panel 8 is attached from above the vehicle body strength member 6 and the air conditioning duct 7. The main harness is a bundle of electric wires in which the core parts of electric wiring used in a vehicle are collected.

  The balance weight 25 has a weight difference in weight between the high-profile mounting portion 24 on which the long component 31 is mounted and the low-profile mounting portion 23 to which the traveling drive device 21 is attached. It is said that.

  The difference in weight is based on the weight of the cart body 11 when the tall mounting portion 24 is loaded with the long component 31 and becomes heaviest. The cart body 11 may be operated so that all the long components 31 are mounted at once and all the work stages 4 are rotated in turn. In this case, the heaviest state of the high-profile mounting portion 24 is when all the long components 31 are mounted.

  Alternatively, the carriage main body 11 receives the work stage 4 and the parts shelf 36 (see FIG. 1) at a position away from the work stage 4 or the receiving position 38 (or sub-assembly position (see FIG. 1)). By transporting mainly long parts 31 used in the next work stage 4 while moving back and forth between parts shooters and transfer devices 37 such as conveyors (see FIG. 1), etc. The operation may be performed so as to reduce the traveling weight of the cart body 11 and improve the efficiency of loading and unloading of parts. In this case, the heaviest state of the high-profile mounting portion 24 is when the heaviest body strength member 6 is placed on the long component holding portion 32 for use in the first work stage 4 (a).

As shown in FIG. 3, the balance weight 25 may have a fixed weight portion 41 fixed to the cart body 11 and a detachable weight portion 42 that can be attached to and detached from the cart body 11. .
The detachable weight portion 42 may be a component that is taken out from the low-profile mounting portion 23 simultaneously with the long component 31.

  Here, for the fixed weight portion 41, for example, a weight made of a lump of metal is used.

  The detachable weight portion 42 is a component that is simultaneously mounted on the low-profile mounting portion 23 when the high-profile mounting portion 24 is in the heaviest state. In this case, the low-profile mounting portion 23 accommodates the air conditioning unit 5 used in the first work stage 4 (a) and a set of fixtures (bolts, nuts, etc.) used in each work stage 4. Since the tool tray 45 and the like are mounted together, the air conditioning unit 5 and the fixture tray 45 can be used as the detachable weight part 42. Therefore, the fixed weight portion 41 has a weight obtained by subtracting the weight of the air conditioning unit 5 and the fixture tray 45 from the weight necessary for the balance weight 25.

  The air conditioning unit 5 is placed and held on the upper shelf 29a of the low-profile mounting unit 23. The upper shelf 29a of the low-profile mounting portion 23 is sized so that the air conditioning unit 5 can be mounted, and a holder for mounting the air conditioning unit 5 is installed. The fixture tray 45 is placed on the middle shelf 29 b of the low-profile mounting portion 23. The middle shelf 29b may be used mainly as the tray mounting portion 46.

  (1) As shown in FIG. 3, the cart body 11 includes a turntable 51.

  Here, the turntable 51 is configured such that a rotating plate 55 is installed on a base 53 via a roller 54 so as to be horizontally rotatable around a vertical rotating shaft. A plurality of the long component holders 32 are installed on the turntable 51 with their circumferential positions shifted. A pole 57 is erected at the center of rotation of the turntable 51. A strength member hooking portion 33, a duct hooking portion 34, and an instrument panel hooking portion 35 (FIG. , See FIG. 5) and the like.

  In this case, the arm portions such as the strength member hooking portion 33, the duct hooking portion 34, and the instrument panel hooking portion 35 are attached in order of the work stage 4 with their positions shifted by about 90 degrees in the circumferential direction. However, the installation interval of the long component holding portions 32 (each arm portion and hook portion thereof) is not limited to an equal interval of 90 degrees, and depends on the number of long component holding portions 32, the size of the long component 31, etc. It can be decided as appropriate (large, small, even, uneven, etc.).

  Further, the turntable 51 includes a biasing means 56 such as a wire reel (see FIG. 3) for returning the position of the long component holder 32 between the base 53 (or the carriage main body 11) and the turntable 55 to the initial state. Reference) is installed. The initial state is, for example, a state in which the vehicle body strength member 6 used in the first work stage 4 (a) faces the work stage 4 side. In this case, the air-conditioning duct 7 used in the third work stage 4 (c) is in a state of being directed to the rear side in the traveling direction of the carriage body 11, and the instrument used in the fourth work stage 4 (d). The ment panel 8 is directed to the side opposite to the work stage 4.

  Note that the upper end side of the pole 57 is pivotally supported using a support member such as a vertical support 58 or a horizontal support arm 59. Each long component holder 32 may be provided with a protective member for protecting the long component 31 to be held, a partition member for partitioning the adjacent long component holders 32 and protecting the long component 31, and the like. .

As described above, the turntable 51 can mount a plurality of components on the component transport carriage 12.
As shown in FIG. 6, an operation unit 61 that rotates the turntable 51 is attached to the turntable 51.
On the other hand, a rotation guide part 62 that rotates the turntable 51 so that the part to be taken out comes to the near side when the operation part 61 comes into contact with the part removal position where the part mounted on the turntable 51 is taken out. Is installed.

  Here, the operation unit 61 rotates with respect to an operation arm 65 protruding in the lateral direction from the upper end side of the pole 57 and a guide shaft portion provided vertically at the tip of the operation arm 65. It has a follower 67 that is pivotally supported. However, the configuration of the operation unit 61 is not limited to the above.

  The part extraction position refers to each work stage 4 described above. In this case, the fourth work stage 4 (d) for mounting the instrument panel 8 is used. For the work stage 4 that picks up parts first, such as the first work stage 4 (a) and the third work stage 4 (c), the turntable is such that the parts to be picked up are on the near side. Since it is only necessary to set the initial state 51, it is not particularly necessary to provide the rotation guide part 62 (of course, the rotation guide part 62 may be provided). The near side is a position closer to the work stage 4.

  The rotation guide unit 62 is attached to, for example, the ceiling of the work stage 4 (in this case, the fourth work stage 4 (d)) or a general-purpose rail 68 (see FIG. 7) installed above the work stage 4. Guide rails. The general-purpose rail 68 is used, for example, for guiding wiring such as electric wires and power cables, attaching illumination, and hanging operation switches and the like. The guide rail as the rotation guide portion 62 is installed on one side of the traveling direction so as not to exceed the position of the rotation center portion of the turntable 51 with respect to the traveling direction of the carriage body 11.

  (2) The rotation guide portion 62 installed at the component extraction position is detachable.

  Here, the rotation guide portion 62 is detachable by attaching a guide rail as the rotation guide portion 62 to the general-purpose rail 68 by using attachment / detachment means 71 such as screwing or clamping. It becomes. In this case, the general-purpose rail 68 extends in parallel with the traveling direction of the carriage body 11, but is not necessarily limited thereto.

  (3) The rotation guide portion 62 can be used in the front-rear inverted state.

  Here, in order to enable the rotation guide portion 62 to be used in the front-rear inverted state, the guide rail may be formed, for example, in a front-rear symmetrical shape or a shape close thereto. In this case, the guide rail has an inclined portion 75 that approaches a line through which the central portion of the rotating base 51 passes as it travels in the traveling direction of the cart body 11, and a central portion of the rotating base 51 as it travels in the traveling direction of the cart body 11. It has a reverse inclined portion 76 that is separated from the passing line, and further includes a key bracket with a linear portion 77 provided between the inclined portion 75 and the reverse inclined portion 76. The bending angles of the inclined portion 75 and the reverse inclined portion 76 with respect to the straight portion 77 may be the same or different.

  In this case, the guide rail is oriented so that the inclined portion 75 is on the near side in the traveling direction and the reverse inclined portion 76 is on the far side in the traveling direction, and is extended to one side of the general-purpose rail 68. It is installed on the rail 68. On the other hand, when used in the front-rear inverted state, the guide rail is oriented so that the inclined portion 75 is on the far side in the traveling direction and the reverse inclined portion 76 is on the near side in the traveling direction. It can be installed on the general-purpose rail 68 in a state of projecting to the other side. However, in this case, it is necessary to change the positional relationship of the general-purpose rail 68 so as to be opposite to the left and right with respect to the line through which the central portion of the turntable 51 passes.

  <Operation> The operation of this embodiment will be described below.

  The parts transport cart 12 travels around various parts shelves 36 provided in the product assembly facility, and a plurality of types of parts are arranged in order of the work stage 4 from each part shelf 36. For example, the air conditioning unit 5 is mounted on the upper shelf 29a of the low-profile mounting portion 23, the fixture tray 45 is mounted on the middle shelf 29b, and the long component holder of the high-profile mounting portion 24 is mounted. The vehicle body strength member 6 is mounted on the strength member hooking portion 33 in 32 (see FIG. 3), the air conditioning duct 7 is mounted on the duct hooking portion 34 (see FIG. 4), and the instrument panel 8 is mounted on the instrument panel hooking portion 35. (See FIG. 5). At this time, the vehicle body strength member 6, the air conditioning duct 7 and the instrument panel 8 are held side by side in the order of the work stage 4. The above-described order can be appropriately changed according to, for example, the situation of the assembly line.

  Next, the parts transport cart 12 goes around each work stage 4 and supplies necessary parts to each work stage 4 in order. For example, in the first work stage 4 (a), the air conditioning unit 5, the fixture tray 45, and the vehicle body strength member 6 are supplied. Next, the air conditioning duct 7 is supplied at the third work stage 4 (c). Finally, the instrument panel 8 is supplied in the fourth work stage 4 (d).

  By sequentially attaching the supplied parts and the like on each work stage 4, a product 3 such as a cockpit module is gradually manufactured on the product assembly cart 2.

  <Effect> According to this embodiment, the following effects can be obtained.

  The parts conveying cart 12 is configured such that parts are supplied by causing the carriage main body 11 on which the parts are mounted to self-run by the traveling drive device 21.

  In this way, by supplying the parts in order to each work stage 4 using the parts transport carriage 12, the parts are placed at a position immediately behind the work stage 4 as shown in FIG. It is not necessary to install a component shelf 36 for placing, a transfer device 37 such as a component shooter or a conveyor for sending the components of the component shelf 36 to the work stage 4, and as shown in FIG. Since the position immediately behind the stage 4 can be widely opened, the space immediately behind the work stage 4 can be used with a margin.

  And the bogie main body 11 is provided with the component mounting part 22 which can mount and mount several types of components in order of the work stage 4, so that a plurality of types used in the plurality of work stages 4 can be used for one bogie main body 11. The parts can be efficiently arranged and mounted. As a result, the cart body 11 capable of handling a plurality of work stages 4 by a single unit is made small and efficient, and the components mounted in order on the cart body 11 are efficiently handled by each work stage 4. Can be taken out. Moreover, since the mounting of the components on the cart body 11 is simply placed in order at predetermined positions, it becomes easy and efficient. Therefore, it contributes to the efficiency of the assembly work of the product 3.

  At this time, the cart body 11 has a stepped shape having a low-profile mounting portion 23 on one side and a high-profile mounting portion 24 on the other side. As a result, various components having different heights can be mounted on the cart body 11 at a time, and the component mounting capability of the cart body 11 can be improved.

  The traveling drive device 21 is attached to the side of the low-profile mounting portion 23 (having a low center of gravity). Accordingly, the low-profile mounting portion 23 can be driven to the front side, the high-profile mounting portion 24 to the rear side, and the rear-side high-profile mounting portion 24 to be pulled. The trolley body 11 travels with better directional stability than when the high-profile mounting section 24 is driven to be pushed from the rear side by the traveling drive device 21 of the low-profile mounting section 23 with the section 24 facing forward. Can be made.

  If a heavy component is mounted on the high-profile mounting portion 24 with respect to the component conveying cart 12 configured as described above, the center of gravity of the cart main body 11 moves to the rear side and the center of gravity increases, so the tall profile of the cart main body 11 is increased. If the mounting portion 24 is tilted rearward, the traveling drive device 21 attached to the low-profile mounting portion 23 may be lifted, and the cart body 11 may not be able to travel.

  Therefore, the balance weight 25 is installed on the low profile mounting portion 23. As a result, the front-side low-profile mounting portion 23 is heavier by the balance weight 25, so that even if heavy components are mounted on the high-profile mounting portion 24, the high-profile mounting portion 24 is prevented from tilting backward, Since the lift of the travel drive device 21 is suppressed, the cart body 11 can be traveled without any trouble and in a stable state.

  At this time, the long component holding part 32 is provided in the high-profile mounting part 24. As a result, the long component 31 can be mounted on the cart body 11 in a vertically oriented state. As a result, it is possible to mount the long component 31 in a compact manner even with the small cart body 11. Further, the long component 31 can be transported by the cart body 11 without any trouble.

  Moreover, since the long component 31 is in the vertical orientation, the long component 31 that is difficult to handle can be mounted with ease. Further, it is possible to eliminate the need to prepare a space for storing the long component 31 in a horizontal state, a component shelf 36, and the like in order to supply the component. Further, since the parts shelf 36 can store the long parts 31 in a vertically oriented state, the parts shelf 36 can be made compact and space-saving, and long parts from the parts shelf 36 to the cart body 11 can be achieved. The transfer of the component 31 is also easy because it is not necessary to change the orientation of the long component 31.

  Furthermore, by providing the plurality of long component parts 32 in order of the work stage 4, as described above, it is possible to efficiently load and take out a plurality of types of long component parts 31 efficiently.

  Since the long component 31 tends to be heavier than other components, if the long component 31 is mounted in a vertically oriented state, the center of gravity of the cart body 11 becomes high, and the There is also a bias in weight, and there is a possibility that the cart body 11 becomes unstable as described above. However, as described above, the balance weight 25 is provided in advance on the side of the low-profile mounting portion 23, so that the long component holding portion 32 is naturally not mounted on the long component holding portion 32. Even when the long component 31 is mounted on the portion 32, the cart body 11 can be stabilized. In addition, since only the balance weight 25 is provided on the low-profile mounting portion 23, the configuration can be simplified.

  At this time, the balance weight 25 is set to a weight difference between the high-profile mounting portion 24 on which the long component 31 is mounted and the low-profile mounting portion 23 to which the traveling drive device 21 is attached. Thereby, the balance weight 25 can be suppressed to the minimum necessary weight. Therefore, when the balance weight 25 becomes too heavy, it is possible to prevent a problem that the traveling performance of the cart body 11 is deteriorated, and the traveling performance of the cart body 11 can be ensured.

  Further, the balance weight 25 is composed of a fixed weight portion 41 and a detachable weight portion 42. The detachable weight part 42 is configured by a part taken out from the low-profile mounting part 23 simultaneously with the long part 31. Accordingly, a part of the components mounted on the low-profile mounting portion 23 can be actively used as the detachable weight portion 42, and the proportion of the fixed weight portion 41 with respect to the entire balance weight 25 accordingly. Thus, it is possible to improve the traveling performance of the cart body 11 after the long component 31 is taken out.

  At this time, the tray 45 is provided with a tray mounting section 46 on the front side (low profile mounting section 23) of the long component holding section 32 and contains a set of fixing tools used in each work stage 4. It is mounted on the section 46 so that it can be conveyed at the same time and simultaneously with the long component 31. As a result, the fixture tray 45 mounted on the tray mounting portion 46 functions as the detachable weight portion 42 of the balance weight 25, so that the weight distribution before and after the component mounting portion 22 is adjusted and the cart body 11 is adjusted. Can be stabilized. In addition, the fixture tray 45 can be used from the product assembly cart in almost all the subsequent work stages 4 by being transferred to the product assembly cart in the first work stage 4 (a). Convenience is high.

  And the effect by the structure characterized by this Example is as follows.

  (Effect 1) The turntable 51 is installed on the component transport carriage 12. As a result, a plurality of components can be mounted and transported on the turntable 51. In addition, at the part take-out position (work stage 4), the necessary parts can be brought closer to the front by turning the turntable 51, so that the work flow is shortened and the part take-out operation is facilitated. The parts can be easily taken out.

  Further, since it is possible to load components from the back side of the turntable 51, it is possible to simultaneously load and remove components.

  At this time, a plurality of long component holders 32 were installed on the turntable 51. As a result, a plurality of long parts 31 can be mounted on the cart body 11, and the long parts 31 to be taken out can be brought closer to the front by the turntable 51. Can be facilitated. Further, by mounting the long component 31 in a vertically oriented state on the turntable 51, the turntable 51 can be reduced in size.

  Then, the operation unit 61 was attached to the turntable 51. Thereby, since the turntable 51 can be rotated by the operation unit 61, the turntable 51 can be easily rotated.

  Furthermore, the rotation guide part 62 was attached to the part extraction position (work stage 4). As a result, when the parts transport carriage 12 moves to the part picking position, as shown in FIG. 7, the operation unit 61 comes into contact with the rotation guide part 62, and as shown in FIG. 8, the operation part 61 is turned into the rotation guide part 62. When the turntable 51 is rotated by being guided by the rotation table 51, the turntable 51 can be automatically operated so that the parts to be taken out are on the near side. In this case, the turntable 51 is rotated approximately 90 degrees, and the duct hooking portion 34 and the instrument panel hooking portion 35 are close to the work stage 4 (b) and the work stage 4 (c). As a result, it is possible to automatically move the parts on the turntable 51 forward without using power or human power. Therefore, the trouble of rotating the turntable 51 can be saved, and the parts can be easily taken out from the turntable 51.

  (Effect 2) The rotation guide part 62 installed in the part extraction position can be attached and detached. As a result, for example, when it is desired to automatically rotate the turntable 51, the rotation guide portion 62 is attached. On the other hand, when it is not necessary to automatically rotate the turntable 51, the rotation guide can be easily set. The part 62 can be removed. Further, since the rotation guide unit 62 can be attached and detached, it is possible to easily cope with a change in the line configuration.

  (Effect 3) The rotation guide part 62 can be used in the front-reverse inverted state. As a result, by attaching the rotation guide part 62 so as to be reversed in the front-rear direction, for example, it is possible to use it in a state where the left and right sides are opposite in accordance with a change in the line configuration. Therefore, the function of the rotation guide part 62 can be expanded.
