DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a component mounting device 1 in one embodiment of the present invention. The component mounting device 1 is a device that repeatedly performs a component mounting operation of mounting components BH on a component mounting object (e.g., a printed circuit board) KB carried in from an upstream process side and carrying it out to a downstream process side. For convenience of explanation, the horizontal direction along the transport direction of the component mounting object KB in the component mounting device 1 is defined as the X direction, the horizontal direction perpendicular to the X direction is defined as the Y direction, and the up-down direction is defined as the Z direction. In addition, the X direction as seen from the worker OP is defined as the lateral direction, and the Y direction as seen from the worker OP is defined as the front-rear direction, and the side farther from the worker OP in the front-rear direction is expressed as the front, and the side closer to the worker OP is expressed as the rear.

[0012] 1, component mounting device 1 is made up of component supply section 1A that supplies components BH, and component mounting section 1B that mounts the components BH supplied by component supply section 1A onto component mounting object KB. Component supply section 1A is equipped with a parts feeder 11 and a feeder cart 12, while component mounting section 1B is equipped with a base 13, a transport section 14, a mounting head 15, a head moving mechanism 16, and a mounting section control device 17.

[0013] 2, part feeder 11 constituting part supply unit 1A has a shape that spreads along the YZ plane as a whole. Part feeder 11 is provided with a supply port (part supply port 11K) for parts BH at the top in front (rear side) as seen from operator OP when attached to feeder cart 12.

[0014] 1, feeder cart 12 has feeder base support section 22 extending upward from vehicle body section 21 that can move on floor surface FL, and a block-shaped feeder base 23 to which part feeders 11 can be detachably attached is provided on the upper part of feeder base support section 22. A plurality of part feeders 11 can be attached to feeder base 23 in a line in the X direction.

[0015] 1, the transport unit 14 constituting the component mounting unit 1B is made up of a pair of belt conveyors 14a and is provided extending in the X direction on the base 13. The transport unit 14 carries in a component mounting target KB sent from the upstream process side and positions it at a predetermined working position.

[0016] 1, the mounting head 15 is equipped with a plurality of nozzles 15N extending downward. The mounting head 15 can move each nozzle 15N in the vertical direction and can also rotate it about a vertical axis. The mounting head 15 can also generate an adsorption force by vacuum pressure at the lower end of each nozzle 15N. The head movement mechanism 16 is composed of, for example, an XY table mechanism, and moves the mounting head 15 along a horizontal plane (XY plane) in the area above the base 13.

[0017] 1, a mounting section control device 17 is provided within the base 13. The mounting section control device 17 controls the operation of each section of the component mounting section 1B. Specifically, the mounting section control device 17 controls the transport operation of the component mounting target KB by the transport section 14 and the positioning operation at the work position, and controls the lifting and rotating operations of each of the multiple nozzles 15N equipped to the mounting head 15. The mounting section control device 17 also generates a suction force for the component BH at the lower end of each nozzle 15N, and operates the head moving mechanism 16 to move the mounting head 15.

[0018] When the component mounting device 1 performs a component mounting operation, it first receives and transports the component mounting object KB sent from the upstream process side by the transport unit 14, and positions it at the work position. After the component mounting object KB is positioned at the work position, the head moving mechanism 16 is operated to move the mounting head 15 above the part feeder 11, and each of the multiple nozzles 15N picks up a component BH.

[0019] Once each of the multiple nozzles 15N has picked up a component BH, the mounting head 15 is moved above the component mounting object KB. Then, above the target mounting position set on the component mounting object KB, the nozzle 15N is lowered to mount the component BH at the target mounting position. This operation of the mounting head 15 is repeated until all of the components BH to be mounted on the component mounting object KB have been mounted, at which point the transport unit 14 is operated to transport the component mounting object KB to the downstream process side. This completes the component mounting operation for each component mounting object KB by the component mounting device 1.

[0020] In the component mounting device 1 having such a configuration, the present embodiment is characterized by the configurations of the parts feeder 11 and the feeder cart 12 that constitute the component supply section 1A, which will be described below.

[0021] First, the feeder cart 12 will be described. In Fig. 2 and Fig. 3, a platform portion 23D is formed in a front region (region on the rear side as seen from the worker OP) of the upper surface of a feeder base 23 provided in the feeder cart 12, the platform portion 23D being located at a position where the upper surface is higher than a rear region (region on the front side as seen from the worker OP) of the feeder base 23. A plurality of feeder attachment members 24 are provided on the platform portion 23D and arranged at intervals in the X direction.

[0022] Each feeder mounting member 24 is made of a rod-shaped member having a "T"-shaped cross section extending in the Y direction. The space between two adjacent feeder mounting members 24 is shaped like an inverted "T" with the "T" turned upside down, and hereinafter this space will be referred to as feeder mounting portion 25.

[0023] 2 and 3, a positioning guide 26 is attached to the rear region of the upper surface of the feeder base 23. As shown in FIG. 4, the positioning guide 26 is made of a plate-like member extending in the horizontal direction (X direction). On the upper surface of the positioning guide 26, a plurality of wall portions 26F are provided lined up in the X direction at regular intervals. Between two adjacent wall portions 26F, a positioning groove 26M is formed with which a positioning protrusion 56 of the part feeder 11, which will be described later, engages. In this way, the positioning guide 26 is configured to have a plurality of positioning grooves 26M lined up in the X direction on its upper surface side (FIG. 4).

[0024] 4, a screw insertion hole 26H is provided in the bottom surface of each of two positioning grooves 26M located at both ends of positioning guide 26, and a protrusion engagement hole 26K is provided in the bottom surface of each of the other two positioning grooves 26M other than the two positioning grooves 26M with the screw insertion holes 26H provided therein. Two alignment protrusions 23T that engage with the two protrusion engagement holes 26K of positioning guide 26 are provided on the upper surface of feeder base 23 so as to protrude upward, and screw holes 23H (FIG. 4) are provided at two positions that match with the two screw insertion holes 26H when the two alignment protrusions 23T are engaged with the two protrusion engagement holes 26K.

[0025] To attach the positioning guide 26 to the upper surface of the feeder base 23, first, the positioning guide 26 is placed in a positioned state on the upper surface of the feeder base 23 by fitting the two projection engagement holes 26K of the positioning guide 26 into the two alignment projections 23T of the feeder base 23. When the two screw insertion holes 26H on the positioning guide 26 and the two screw holes 23H on the feeder base 23 are aligned, the screws 27 are inserted through the two screw insertion holes 26H and screwed into the corresponding screw holes 23H. Thus, the positioning guide 26 is attached to the upper surface of the feeder base 23 in a state where it is accurately positioned with respect to the feeder base 23 by the alignment projections 23T.

[0026] Here, the screw 27 is, for example, a countersunk screw, and when the screw 27 inserted into the screw insertion hole 26H is screwed into the screw hole 23H, the top surface of the head of the screw 27 is at the same height as the bottom surface of the positioning groove 26M of the positioning guide 26 or at a lower height than the bottom surface of the positioning groove 26M. Also, the upper end of the alignment protrusion 23T engaged with the protrusion engagement hole 26K does not protrude upward from the protrusion engagement hole 26K (i.e., it is located at a position lower than the bottom surface of the positioning groove 26M).

[0027] 2 and 5, each of the multiple feeder mounting parts 25 lined up in the horizontal direction (X direction) on feeder base 23 and the positioning guides 26 corresponding to each feeder mounting part 25 form one slot 28. That is, feeder base 23 is configured to have multiple slots 28 lined up in the X direction on its upper surface. In this embodiment, two positioning guides 26 are attached to the upper surface of feeder base 23, and multiple positioning grooves 26M located on the upper surface of feeder base 23 are provided separately for the two positioning guides 26.

[0028] Thus, in this embodiment, the positioning grooves 26M are arranged side by side in the lateral direction (X direction), which is a horizontal direction perpendicular to the sliding direction (Y direction) of the part feeder 11 relative to the feeder base 23, so that a plurality of positioning grooves 26M are formed in one positioning guide 26. Also, the plurality of positioning grooves 26M on the feeder base 23 are provided separately in a plurality (two in this case) of positioning guides 26 provided on the upper surface of the feeder base 23.

[0029] In this embodiment, the positioning guide 26 can be attached and detached to the feeder base 23 by a screw 27 that penetrates the bottom surface of the positioning groove 26M and is screwed into the feeder base 23, and when the positioning guide 26 is attached to the feeder base 23 by the screw 27, the upper surface of the head of the screw 27 does not protrude above the bottom surface of the positioning groove 26M.

[0030] 2 and 3, a feeder stopper 31 is provided at the end of the front side (the rear side as seen from the operator OP) of feeder base 23. Feeder stopper 31 has a shape that spreads out along the XZ plane as a whole and extends upward. Upper and lower parts of feeder stopper 31 are provided with upper pin insertion holes 31A and lower pin insertion holes 31B in positions corresponding to each slot 28.

[0031] 2, 3, and 6(a) and (b), a protruding member 32 is provided on the underside of the rear part (the front side as seen from the operator OP) of the feeder base 23, protruding downward and protruding from the rear of the feeder base 23. A bracket 33 having a shape that spreads out along the XZ plane as a whole and extends downward is detachably provided on the rear part of the protruding member 32.

[0032] 2, 3, and 6(a) and (b), a plurality of lock arms 34 are provided at the rear end of the overhanging member 32, lined up in the X direction in an arrangement corresponding to each of the slots 28. As shown in Fig. 7, the lock arms 34 include a pair of arm plates 34a arranged opposite each other in the X direction and extending in the front-rear direction (Y direction), and an operation pin 34b and a lock pin 34c provided between the pair of arm plates 34a and extending in the X direction.

[0033] In Fig. 3, a plurality of hook-shaped portions 23K are arranged in the X direction at the rear end of the feeder base 23. As shown in Figs. 6(a) and 7, the hook-shaped portions 23K are pivotally supported at the front end of a pair of arm plates 34a by a pivot shaft 34d extending in the X direction. Both ends of the operation pin 34b are supported at the rear end of the pair of arm plates 34a in the front-rear direction. Both ends of the lock pin 34c are supported at the intermediate portion of the pair of arm plates 34a in the front-rear direction. The portion of the lock arm 34 forward of the pivot shaft 34d is biased upward by a biasing spring 34e.

[0034] 2, 3, and 6(a) and (b), a plurality of guide pieces 35 are provided lined up in the horizontal direction (X direction) on the rear end surface of the overhanging member 32 below a plurality of lock arms 34 lined up in the X direction. Each guide piece 35 has a shape that protrudes rearward, and a guide passage 36 is formed between a pair of side surfaces (referred to as "guide surfaces 35G") that face each other in the horizontal direction (X direction) of two adjacent guide pieces 35.

[0035] Thus, in this embodiment, feeder cart 12 includes a plurality of guide pieces arranged side by side in a lateral direction (X direction) that is a horizontal direction perpendicular to a front-rear direction (Y direction) in which part feeder 11 slides relative to feeder base 23, and a pair of surfaces corresponding to the lateral direction of two adjacent guide pieces 35 among the plurality of guide pieces 35 form guide passage 36. As shown in Fig. 5, the portions connected to the rear of each of two guide surfaces 35G form tapered surfaces 35M formed in a tapered shape that widens rearward.

[0036] 2, 3 and 6(a), an air socket 37 is provided at the rear end of the overhanging member 32. A bogie-side connector 38 and an engagement pin 39 are provided at the upper portion of a bracket 33 that is detachable from the overhanging member 32.

[0037] 2, 3 and 6(a), the air socket 37, the bogie-side connector 38 and the engagement pin 39 are positioned in this order from above, and each protrudes rearward. The air socket 37, the bogie-side connector 38 and the engagement pin 39 are aligned in the X direction, and one set of one air socket 37, one bogie-side connector 38 and one engagement pin 39 aligned in the vertical direction is disposed corresponding to each of the multiple slots 28.

[0038] The air socket 37 is connected to an air pipe in the component mounting unit 1B to which air is supplied from an air supply source (not shown) installed outside the component mounting unit 1B. The cart side connector 38 is connected to an electric cable in the component mounting unit 1B to which power is supplied from a power source (not shown) installed outside the component mounting unit 1B.

[0039] 2, 3 and 6(a), a carriage-side control board 41, which is a control board on the feeder carriage 12 side, is attached to the front (rear) area of ​​the bracket 33. In detail, the carriage-side control board 41 is attached to the bracket 33 in a vertical position with its thickness direction (normal line NR to the surface) facing the sliding direction of the part feeder 11 relative to the feeder base 23 (the extension direction of the feeder mounting member 24, the Y direction).

[0040] In this manner, in this embodiment, the cart-side control board 41 provided on the feeder cart 12 is provided in a vertical position rather than a horizontal position as in the conventional case, so that the dimension of the feeder base 23 in the depth direction (Y direction) can be shortened, and the entire feeder cart 12 can be made compact.

[0041] 6(a), each of the multiple cart-side connectors 38 is electrically connected to the cart-side control board 41 by a cart-side wiring 41C. That is, the cart-side control board 41 is configured as a unit (control board unit 41U) integrated with the cart-side connectors 38 and the bracket 33.

[0042] As described above, the bracket 33 is detachable from the overhanging member 32 of the feeder base 23, so that the entire control board unit 41U including the bogie-side control board 41 and the bogie-side connector 38 can be removed from the feeder base 23 by removing the bracket 33 from the feeder base 23. This makes it extremely easy to perform maintenance work on the bogie-side control board 41 and the bogie-side connector 38.

[0043] 6(a) and (b), a floating mechanism 43 is provided between the feeder base support section 22 of the feeder cart 12 and the feeder base 23, which supports (floatingly supports) the feeder base 23 so that the upper surface of the feeder base 23 is in a substantially horizontal reference position. The floating mechanism 43 is configured to include a fixed side member 43a provided on the upper end of the feeder base support section 22, and a movable side member 43b located above the fixed side member 43a and connected to the feeder base 23.

[0044] In a natural state where no external forces other than its own weight are applied to the feeder base 23 (fixed member 43a), the feeder base 23 (fixed member 43a) is in contact with the upper surface of the movable member 43b from above and is in a horizontal position (reference position), but when an external force is applied, the feeder base 23 becomes tilted from the reference position in response to the external force. Specifically, when an upward external force is applied to the rear end of the feeder base 23, the feeder base 23 (and therefore the movable member 43b) becomes in a position with its front end lowered, and conversely, when a downward external force is applied to the rear end of the feeder base 23, the feeder base 23 becomes tilted from the reference position in response to the external force.

[0045] In this way, the feeder cart 12 in this embodiment is equipped with a floating mechanism 43 that is interposed between the feeder base 23 and the feeder base support part 22 that supports the feeder base 23 from below, and that supports the feeder base 23 in a floating manner.

[0046] 6(a) and (b), a contact member 44 is provided on the lower surface of the feeder base 23 so as to protrude downward. Meanwhile, a contacted member 45 is provided on the upper surface of the fixed side member 43a constituting the floating mechanism 43 so as to protrude upward. As shown in FIG. 6(a), the contact member 44 is made of a member having a channel-shaped cross section extending in the horizontal direction (X direction), and a plurality of the contact members 44 are provided side by side in the horizontal direction. The fixed side member 43a is also made of a member having a channel-shaped cross section extending in the horizontal direction (X direction).

[0047] When the feeder base 23 is in the standard position, the contact member 44 contacts the contacted member 45 from above (see the standard contact point T0 shown in FIGS. 6(a) and 6(b)). Therefore, the feeder base 23 cannot be easily tilted from the standard position in the direction of lowering the front end side (tilting forward).

[0048] In this manner, in this embodiment, the abutment member 44, which is a base side member protruding downward from the underside of the feeder base 23, and the abutted member 45, which is a support side member provided on the feeder base support part 22 that supports the feeder base 23 (or directly on the fixed side member 43a) and abuts against the abutment member 44, form a forward tilt regulating part 46 that regulates the range of motion of the forward tilting movement in which the feeder base 23 tilts in the direction lowering the front end side from the approximately horizontal reference posture.

[0049] When an external force acts to forcibly tilt feeder base 23 forward from a state in which the abutting member 44 abuts against abutted member 45 and the forward tilt of feeder base 23 from the reference posture is restricted, feeder base 23 tilts forward with a forward tilt abutment point T1, which is forward of the standard abutment point T0, as a fulcrum. Note that even in this case, the forward tilt is limited to a range in which a tilt limiting stopper (forward tilt limiting stopper 47, FIG. 6(a)) provided on movable member 43b abuts against fixed member 43a and feeder base 23 cannot tilt forward any further (FIG. 8(a)).

[0050] Thus, the feeder cart 12 in this embodiment includes, in addition to the floating mechanism 43 interposed between the feeder base support part 22 and the feeder base 23 to floatingly support the feeder base 23, a forward tilt restriction part 46 that restricts the range of forward tilting of the feeder base 23 in a direction to lower the front end side from a substantially horizontal reference position. Therefore, while the feeder base 23 is floatingly supported by the floating mechanism 43, the forward tilting of the feeder base 23 from the substantially horizontal reference position is restricted by the forward tilt restriction part 46, so that even if the center of gravity of the feeder base 23 is located forward due to compactification of the feeder base 23, the feeder base 23 is prevented from tilting forward due to its own weight.

[0051] On the other hand, when an external force acts on the feeder base 23 in the reference position in the direction of lowering the rear end, the feeder base 23 tilts backward in response to the external force. Then, when the tilt angle from the reference position reaches a certain amount, the feeder base 23 comes into contact with the rear end 43E of the fixed member 43a from above. Then, when an external force acts to tilt the feeder base 23 further backward from the state in which the feeder base 23 abuts against the rear end 43E of the fixed member 43a (FIG. 8(b)), the feeder base 23 tilts backward with the abutment point with the rear end 43E of the fixed member 43a (abutment point T2 during rearward tilt, FIG. 8(b)) as a fulcrum. Even in this case, the rearward tilt is limited to a range until the tilt limiting stopper (rearward tilt limiting stopper 49, FIG. 6(a)) provided on the fixed member 43a abuts against the movable member 43b and the feeder base 23 cannot tilt backward any more (FIG. 8(b)).

[0052] As described above, the feeder cart 12 in this embodiment is provided with a rearward tilt restricting portion that restricts the range of rearward tilting motion in which the feeder base 23 tilts in a direction lowering the rear end side from the reference position.

[0053] Next, the parts feeder 11 will be described. In Fig. 9 and Fig. 10(a) and (b), the parts feeder 11 has a housing 51 having a thin shape with a small dimension in the horizontal direction (X direction) as a whole. A component supply mechanism (not shown) is provided inside the housing 51 for conveying the carrier tape CT from the rear of the housing 51 toward the component supply port 11K located at the upper front part of the housing 51, and a handle part 51D is provided at the upper rear part of the housing 51.

[0054] 2, 9, and 10(a), the portion (part of housing 51) protruding downward from the rear of housing 51 serves as downward extension 52. In this embodiment, as shown in FIG. 1, part feeder 11 is assumed to be a tape feeder that supplies parts BH to part supply port 11K by pulling out carrier tape CT, in which parts BH are stored, from reel RL and transporting it, but part feeder 11 is not limited to a tape feeder and may be a bulk feeder, stick feeder, or the like.

[0055] 9 and 10(a) and (b), upper and lower positioning pins, that is, upper pin 53 and lower pin 54, are provided at the front end of housing 51 so as to protrude forward. A slider 55 is provided at the front of housing 51 in the front-rear direction (Y direction) so as to extend along the bottom surface of housing 51, and a positioning protrusion 56 is provided at the middle of housing 51 in the front-rear direction so as to protrude downward.

[0056] The slider 55 has an inverted T-shaped cross section that can be inserted into a space (the above-mentioned feeder mounting portion 25) formed between two adjacent feeder mounting members 24 among a plurality of feeder mounting members 24 provided on the upper surface (specifically, the upper surface of the platform portion 23D) of the feeder base 23. As shown in Figs. 2, 9, and 10(a) and (b), the slider 55 has a notch 55K in the middle in the front-rear direction (Y direction) of the housing 51, i.e., in the sliding direction relative to the feeder base 23, and is divided into a portion (front slider 55a) located in front of the notch 55K and a portion (rear slider 55b) located behind the notch 55K.

[0057] That is, in this embodiment, a notch 55K is provided in the middle of the slider 55 of the part feeder 11 in the sliding direction (Y direction) relative to the feeder base 23, and the slider 55 comprises a front slider 55a located forward of the notch 55K and a rear slider 55b located rearward of the notch 55K.

[0058] 2, 9, and 10(a) and (b), the positioning protrusion 56 is a cylindrical pin member. The positioning protrusion 56 is provided on an extension line of the slider 55, that is, on the center line of the slider 55 along the Y axis.

[0059] 9, 10(a) and 11, downward extension portion 52 is provided with a hook-shaped member 61, an unlocking member 62, an air plug 63, a feeder-side connector 64 and a bottom plate member 65. Hook-shaped member 61, unlocking member 62, air plug 63 and feeder-side connector 64 are each provided to protrude forward from the front surface of downward extension portion 52.

[0060] 10(a) and 11, the hook-shaped member 61 is an engagement member (feeder-side engagement member) on the parts feeder 11 side that engages with the lock pin 34c, which is the engagement member (cart-side engagement member) on the dolly side, and is made of a plate-shaped member extending along the YZ plane. The base end portion on the rear end side of the hook-shaped member 61 is fixed to the housing 51 (more specifically, the downward extension portion 52).

[0061] 11 and 12, the upper edge of the hook-shaped member 61 is a slope 61a that slopes upward from the tip (front end) side to the rear. A tip-side recess 61b that opens upward is provided at the tip of the hook-shaped member 61, and a base-side recess 61c that also opens upward is provided at the base end of the hook-shaped member 61. The rear upper edge of the tip-side recess 61b and the front upper edge of the base-side recess 61c are connected to the slope 61a.

[0062] 11, the unlocking member 62 is made of a plate-like member along the YZ plane like the hook-shaped member 61, and is provided to the side of the hook-shaped member 61. As also shown in Fig. 12, the upper surface (upper edge) of the unlocking member 62 forms an inclined surface 62a that decreases in height from the rear to the front.

[0063] 12 and 13(a) and (b), the unlocking member 62 has an intermediate portion pivoted by a front pivot pin 71 located inside the downward extending portion 52. Therefore, the unlocking member 62 is free to swing in a plane along the YZ plane around the front pivot pin 71, and can move between a reference position (FIG. 13(a)) in a substantially horizontal position and an unlocked position (FIG. 13(b)) in which the tip (front end) is raised from the reference position.

[0064] 11 and 12, a lever member 72 is provided at a rear position of the lock release member 62 within the downward extension portion 52. The lever member 72 is a plate-shaped member extending in the Y direction as a whole, and its middle portion is pivoted by a rear pivot pin 73 located within the downward extension portion 52. Therefore, the lever member 72 is freely swingable within a plane along the YZ plane around the rear pivot pin 73, and can move between a first position (FIG. 13(a)) where the rear portion is lowered and the front portion 72M is raised, and a second position (FIG. 13(b)) where the rear portion is raised and the front portion 72M is lowered.

[0065] 10(a) and 13(a) and (b), a slide space 51S extending in the Y direction is provided in the upper rear portion of the housing 51. A slide member 74 extending in the Y direction is inserted into the slide space 51S from the rear side of the housing 51.

[0066] The slide member 74 is slidable in the Y direction within the slide space 51S, and can move between a non-operation position (FIG. 13(a)) located at the frontmost position within the slide space 51S and an operation position (FIG. 13(b)) located at the rearmost position within the slide space 51S. When the slide member 74 is located at the operated position, it abuts from behind against an inner wall 51N within the housing 51 that forms the slide space 51S (FIG. 13(a)), and when located at the operation position, it protrudes rearward from the housing 51 (FIG. 13(b)).

[0067] 9 and 10(a), an operation knob 75 is attached to the rear end of the slide member 74. The base end of the operation knob 75 is pivoted to the slide member 74 by a knob pivot pin 75P, and is freely swingable within a plane along the YZ plane around the knob pivot pin 75P. The operation knob 75 can be moved between a stored position where the tip end is located above the base end (see the operation knob 75 shown by the solid line in FIG. 13(a)) and a use position where the tip end is located rearward of the base end (see the operation knob 75 shown by the dashed line in FIG. 13(a)).

[0068] 10(a) and 13(a) and (b), a pulley 76 is provided at a position in front of slide member 74 inside housing 51. One end (upper end) of wire 77 is connected to the rear end of slide member 74, and the other end (lower end) of wire 77 is attached to the rear end of lever member 72 via pulley 76 (FIGS. 10(a) and 13(a) and (b)).

[0069] As shown in Fig. 13(a), when the operator OP is not operating the operation knob 75, the slide member 74 is located at a non-operation position with its front end abutting against the inner wall 51N of the housing 51, and the lever member 72 is located at a first position with its front part 72M raised. The front part 72M of the lever member 72 abuts from above against the operated pin 62P provided at the rear end of the lock release member 62 and protruding in the X direction, but the lever member 72 does not press down the operated pin 62P, and the lock release member 62 is located at a reference position in a substantially horizontal posture. The tip-side recess 61b and the base-side recess 61c of the hook-shaped member 61 are exposed above the inclined surface 62a of the lock release member 62 in a side view (Fig. 13(a)).

[0070] When the operator OP pulls the operation knob 75 backward from the state in which the operation knob 75 is not operated as described above (FIG. 13(a)→FIG. 13(b)), the slide member 74 moves so as to protrude rearward from the housing 51 and is positioned at the operation position, and the rear end of the lever member 72 is lifted via the wire 77. As a result, the lever member 72 swings about the rear pivot pin 73 and is positioned at the second position (FIG. 13(b)), and the front portion 72M presses down the operated pin 62P of the unlocking member 62, so that the unlocking member 62 swings about the front pivot pin 71 and is positioned at the unlocking position. When the unlocking member 62 is positioned at the unlocking position, the tip-side recess 61b and the base-side recess 61c of the hook-shaped member 61 are each hidden below the inclined surface 62a of the unlocking member 62 in a side view (FIG. 13(b)).

[0071] When the operator OP releases the state in which the operation knob 75 is pulled backward, the lever member 72 returns to the first position due to its own weight balance, and the pressed-down operation of the operated pin 62P of the lock release member 62 is released. As a result, the lock release member 62 returns to the reference position in which it is in a substantially horizontal position due to its own weight balance (FIG. 13(b) → FIG. 13(a)), and the slide member 74 is pulled by the wire 77 and returns to the non-operated position (FIG. 13(a)).

[0072] As shown in Figures 11, 12 and 14, a plate member 81 is provided on the front side of the downward extension 52. The plate member 81 is made of a substantially rectangular plate-like member extending in the vertical direction. The air plug 63 is attached to the middle part of the plate member 81 by penetrating it in the thickness direction, and the middle part in the longitudinal direction (Y direction) of the air plug 63 is held in a fastened state by two fixing nuts 81N (Figures 11 and 14). The air plug 63 is a coupling member (feeder-side coupling member) on the part feeder 11 side of the air coupling formed between the feeder cart 12 and the part feeder 11 attached thereto.

[0073] 11, 12 and 14, the upper and lower ends of plate member 81 are attached to the front surface of downward extension portion 52 by two stepped bolts 82 (upper stepped bolt 82a and lower stepped bolt 82b). As a result, one end side 63a of air plug 63, the middle portion of which is held by plate member 81, is located inside housing 51, and the other end side 63b of air plug 63 is located outside housing 51 (in front of downward extension portion 52).

[0074] Here, plate member 81 is attached in a state in which it can move freely relative to the front surface of downward extension portion 52 (i.e., the outer surface of housing 51) by air plug holding portion 83 (Figs. 11, 12 and 14) composed of plate member 81 and two stepped bolts 82. To explain this in detail, as shown in Figs. 15(a), (b) and (c), bolt insertion portions 84 (upper bolt insertion portion 84a and lower bolt insertion portion 84b) are provided at the upper and lower positions of plate member 81, i.e., at two upper and lower positions positioned on either side of the holding portion of air plug 63, and two stepped bolts 82 (upper stepped bolt 82a and lower stepped bolt 82b) are screwed into bolt holes 51H provided in upper and lower plate holding portions 51T, which are members on the housing 51 side, respectively. Here, the height dimension of the collar portion 82C, which is the non-threaded portion of the stepped bolt 82, is greater than the thickness dimension of the plate member 81 (Figure 15 (a)), and therefore the plate member 81 is able to move freely within the height range of the collar portion 82C of the stepped bolt 82.

[0075] Thus, in this embodiment, the part feeder 11 is provided with an air plug 63 which is a feeder-side coupling member which is a coupling member on the part feeder 11 side of the air coupling formed between the part feeder 11 and the feeder cart 12 on which the part feeder 11 is slid and attached, and an air plug holding portion 83 which serves as a feeder-side coupling member holding portion which holds the air plug 63 horizontally and freely movable relative to the housing 51 of the part feeder 11. The air plug holding portion 83 is made up of a plate member 81 to which the air plug 63 is attached, and a plurality of stepped bolts 82 which serve as plate member mounting members which mount the plate member 81 in a freely movable state relative to the housing 51 of the part feeder 11 to hold the air plug 63 in a substantially horizontal position, and the two stepped bolts 82 are adapted to be inserted into two bolt insertion portions 84 which are provided above and below the portion of the plate member 81 to which the air plug 63 is attached.

[0076] When attaching the plate member 81 to the front surface of the downward extension portion 52 (i.e., the outer surface of the housing 51), first, the plate member 81 is tilted 90° to a position extending laterally (FIG. 15(a)). Then, the upper bolt insertion portion 84a is engaged with the collar portion 82C of the upper stepped bolt 82a from the lateral direction (FIG. 15(b)), and the plate member 81 is rotated 90° with the upper stepped bolt 82a as a fulcrum so that the lower end side of the plate member 81 is lowered. Then, the lower bolt insertion portion 84b is engaged with the collar portion 82C of the lower stepped bolt 82b. This results in the plate member 81 being attached to the housing 51 (FIG. 15(c)).

[0077] Thus, in this embodiment, the plate member 81 is configured such that one of the two bolt insertion portions 84 (here, upper bolt insertion portion 84a) opens at the upper edge of the plate member 81, and the other of the two bolt insertion portions 84 (here, lower bolt insertion portion 84b) opens at the side edge of the plate member 81. For this reason, when attaching the plate member 81 to the housing 51, this can be done with the two shoulder bolts 82 each screwed into the plate holding portion 51T of the housing 51.

[0078] In this embodiment, the upper bolt insertion portion 84 opens at the upper edge of the plate member 81 and the lower bolt insertion portion 84 opens to a side of the plate member 81, but the lower bolt insertion portion 84 may open at the lower edge of the plate member 81 and the upper bolt insertion portion 84 may open at a side edge of the plate member 81. In other words, it is sufficient that one of the two bolt insertion portions 84 provided on the plate member 81 opens at the upper edge or lower edge of the plate member 81 and the other of the two bolt insertion portions 84 opens at the side edge of the plate member 81.

[0079] 12 and 14, an air control valve unit 91 and two tubes for air piping (a first tube 92 and a second tube 93) are arranged inside a housing 51. The first tube 92 and the second tube 93 are each made of an elastic body such as rubber, and can be bent and deformed.

[0080] One end (lower end) of the first tube 92 is connected to a first connection port 91a, which is one of two air piping connection ports protruding upward from the valve unit 91, and the other end (upper end) is connected to one end 63a of the air plug 63. That is, the first tube 92 is provided inside the housing 51, and is an air piping tube made of an elastic body with one end connected to the first connection port 91a, which is an air piping connection port located inside the housing 51, and the other end connected to one end 63a of the air plug 63, which is a feeder-side coupling member.

[0081] On the other hand, one end (lower end) of the second tube 93 is connected to a second connection port 91b, which is the other of the two air piping connection ports provided in the valve unit 91, and the other end (upper end) is connected to an air-operated device (not shown) that is installed in the housing 51 and operates by receiving a supply of air. Air introduced into the first tube 92 through the air plug 63 is controlled in the valve unit 91 and sent to the air-operated device through the second tube 93.

[0082] In this embodiment, as shown in Fig. 14, the first connection port 91a faces upward in the figure, and one end of the air plug 63 faces leftward in the figure. The first tube 92 is arranged in the housing 51 so that, with one end connected to the first connection port 91a and the other end attached to one end of the air plug 63, an elastic restoring force acts to return the first tube 92 from the state shown by the dashed line in Fig. 14 to the state shown by the solid line. In other words, the first tube 92 is arranged so that the elastic restoring force of the first tube 92 in the vicinity of the end (one end) connected to the first connection port 91a has a component in a direction pressing the air plug 63 from the inside to the outside of the housing 51.

[0083] Here, the air plug 63 is held horizontally and freely movable relative to the housing 51 by an air plug holding portion 83 consisting of a plate member 81 and two shoulder bolts 82, and as can be seen from Figure 14 and Figures 15(a), (b), and (c), the length of one end located outside the housing 51 is greater than the length of the other end located inside the housing 51, so that the air plug 63 will assume a tip-down position in which the side located outside the housing 51 drops down due to its own weight.

[0084] However, in this embodiment, the air plug 63 is pressed from the inside to the outside of the housing 51 by the first tube 92, and is held in a horizontal position with both the upper and lower ends of the plate member 81 pressed from the inside against the heads of the two stepped bolts 82. In this state in which both the upper and lower ends of the plate member 81 are pressed from the inside against the heads of the two stepped bolts 82 by the first tube 92, the air plug 63 held by the plate member 81 is held in a horizontal position in a floating state by the elastic force of the first tube 92.

[0085] As described above, the parts feeder 11 in this embodiment is equipped with an air plug holding portion 83 (a plate member 81 and two shoulder bolts 82) serving as a feeder-side coupling member holding portion which holds the air plug 63 horizontally and freely movable relative to the housing 51, and which positions one end side 63a of the air plug 63 inside the housing 51 and the other end side 63b of the air plug 63 outside the housing 51, and a first tube 92 which is an air piping tube made of an elastic body and is provided inside the housing 51 and has one end connected to a first connection port 91a which is an air piping connection port located inside the housing 51 and the other end connected to the one end side 63a of the air plug 63, and the air plug 63 is in a state where it is pressed from the inside to the outside of the housing 51 by the first tube 92.

[0086] For this reason, in parts feeder 11 of this embodiment, even if air plug 63 protrudes significantly outside housing 51, air plug 63 is prevented from being in a tip-down position due to its own weight relative to housing 51, and air plug 63 can be smoothly fitted into air socket 37 on feeder cart 12 when attached to feeder cart 12. When first tube 92 is arranged to press air plug 63 from the inside to the outside of housing 51, force FC with which first tube 92 presses air plug 63 increases as the outer diameter of first tube 92 increases and as the length of first tube 92 increases.

[0087] 12, a feeder-side control board 94 is provided behind the valve unit 91 in the downward extension 52. The feeder-side control board 94 has a function of controlling the operation of each part feeder 11. The feeder-side control board 94 is electrically connected to the feeder-side connector 64 by internal feeder wiring 95. The feeder-side connector 64 is an electrical connector on the part feeder 11 side of the electrical coupling formed with the feeder cart 12.

[0088] 12, the bottom plate member 65 is provided extending in the Y direction on the lower surface of the downward extending portion 52. The front end portion of the bottom plate member 65 protrudes forward beyond the downward extending portion 52, and the protruding portion is bent upward and extends to form a bent portion 65K. A pin engagement hole 65H penetrating the bottom plate member 65 in the plate thickness direction (Y direction) is provided in the bent portion 65K.

[0089] When attaching the part feeder 11 having such a configuration to the feeder base 23 of the feeder cart 12, the operator OP inserts the sliders 55 (front slider 55a and rear slider 55b) of the part feeder 11 into the feeder attachment portion 25 of one of the slots 28 selected from the rear of the feeder base 23, and pushes the housing 51 of the part feeder 11 forward (toward the rear) (arrow A1 shown in FIG. 16(a)). As a result, first the front slider 55a advances rearward within the feeder attachment portion 25 of the slot 28, and then the rear slider 55b advances rearward within the feeder attachment portion 25.

[0090] As described above, when the rear slider 55b of the part feeder 11 advances inside the feeder attachment portion 25, the upper and lower positioning pins (upper pin 53 and lower pin 54) located at the front end of the housing 51 fit into the upper and lower pin insertion holes (upper pin insertion hole 31A and lower pin insertion hole 31B) provided in the feeder stopper 31, and the front end of the part feeder 11 abuts against the feeder stopper 31 (FIG. 16(b)). This positions the front of the housing 51 in the front-to-rear direction (Y direction). Also, as the slider 55 advances inside the feeder attachment portion 25, the positioning protrusion 56 provided in the middle part of the housing 51 in the front-to-rear direction advances from the rear and engages with the positioning groove 26M located at the rear of the feeder attachment portion 25 (FIG. 16(b)).

[0091] 17(a) is a view of the slider 55 attached to the feeder attachment portion 25 as seen from the rear of the feeder cart 12. As can be seen from this figure, the lower surface of the slider 55 in the feeder attachment portion 25 is spaced apart from the upper surface of the feeder base 23. The front part of the housing 51 is positioned in the lateral direction (X direction) by the side surfaces of the slider 55 being sandwiched between two adjacent feeder attachment members 24 forming the feeder attachment portion 25, and is positioned in the height direction (Z direction) by the lower pin 54 fitting into the lower pin insertion hole 31B and the positioning protrusion 56 fitting into the positioning groove 26M as described above. In this state, the lower surface of the housing 51 is spaced apart from the upper surface of the feeder attachment member 24, and the lower surface of the slider 55 is spaced apart from the upper surface of the feeder base 23 (specifically, the upper surface of the platform portion 23D) (FIG. 17(a)).

[0092] 17(b) is a view of the positioning protrusion 56 engaged with the positioning groove 26M as viewed from the rear of the feeder cart 12. As can be seen from this figure, the lower end of the positioning protrusion 56 in the positioning groove 26M abuts against the bottom surface of the positioning groove 26M. The middle part of the housing 51 is positioned in the height direction (Z direction) by the lower end of the positioning protrusion 56 abutting against the bottom surface of the positioning groove 26M.

[0093] Thus, in this embodiment, the positioning protrusion 56 protruding downward from the middle part of the housing 51 has the function of positioning the part feeder 11 in the height direction relative to the feeder base 23 (more specifically, the middle part of the housing 51 in the front-to-rear direction) when attached to the feeder base 23.

[0094] 17(b), the positioning protrusion 56 is fitted into the two walls 26F constituting the positioning groove 26M with a clearance smaller than the tolerance, and the positioning protrusion 56 is slidable in the Y direction within the positioning groove 26M but is restricted in the X direction. Therefore, by engaging the positioning protrusion 56 with the positioning groove 26M, the rear part of the parts feeder 11 attached to the feeder base 23 is positioned in the lateral direction (X direction) relative to the feeder base 23.

[0095] As described above, the heads of the screws 27 that attach the positioning guide 26 to the upper surface of the feeder base 23 do not protrude into the positioning groove 26M, and the height dimension of the alignment protrusion 23T is set so that its upper end does not protrude upward from the bottom surface of the positioning groove 26M. Therefore, when the part feeder 11 is attached to or detached from the feeder base 23, the positioning protrusion 56 of the part feeder 11 does not interfere with the screws 27 in the positioning groove 26M or the alignment protrusion 23T. Therefore, the part feeder 11 can be attached to or detached from the feeder base 23 smoothly, and there is no risk of damaging the positioning protrusion 56 of the part feeder 11.

[0096] Thus, in this embodiment, in the process of mounting the parts feeder 11 on the feeder cart 12, the positioning guide 26 having the positioning groove 26M that receives the positioning protrusion 56 and supports the lower surface of the positioning protrusion 56 to position the parts feeder with respect to the feeder base 23 is detachable from the feeder base 23. This allows the positioning guide 26 to be manufactured as a separate member from the feeder base 23, and eliminates the need for machining the top surface of the feeder base 23 to form a complex uneven shape as in the conventional method, allowing the feeder base 23 to be manufactured at low cost.

[0097] In addition, because positioning guide 26 is detachable from feeder base 23, maintenance work such as cleaning of positioning groove 26M can be easily performed. Even if wall portion 26F or the like that forms positioning groove 26M is damaged due to wear, there is no need to replace the entire feeder base 23.

[0098] In addition, in this embodiment, since multiple positioning grooves 26M are formed in one positioning guide, maintenance of the multiple positioning grooves 26M can be performed all at once, and the efficiency of the maintenance work can be improved. In addition, in this embodiment, the multiple positioning grooves 26M arranged in the sliding direction (X direction) of the parts feeder 11 are not all formed in one positioning guide 26, but the multiple (all) positioning grooves 26M are provided separately in the multiple positioning guides 26 (FIG. 4). Therefore, the positioning guide 26, which tends to be long, can be made compact in size, making it easy to handle and store.

[0099] In the process of mounting the part feeder 11 to the feeder base 23 as described above, the air plug 63, which is a feeder-side coupling member, and the air socket 37, which is a carriage-side coupling member, are fitted together to form an air coupling. This makes it possible to supply air from the feeder carriage 12 side (i.e., the part mounting unit 1B side) to the part feeder 11 side.

[0100] As described above, the air plug 63 is attached by the air plug holding portion 83 in a state in which it can move freely relative to the downward extension portion 52 (i.e., relative to the housing 51), so that even if the housing 51 of the part feeder 11 is slightly tilted laterally when the part feeder 11 is attached to the feeder attachment portion 25, the air plug 63 can be smoothly fitted into the air socket 37 on the feeder cart 12 side. Furthermore, the air plug 63 is prevented from being in a tip-down position and is maintained in a horizontal position by being pressed from the inside to the outside of the housing 51 by the first tube 92, so that the air plug 63 can be smoothly fitted into the air socket 37 on the feeder cart 12 side when the part feeder 11 is attached to the feeder cart 12. Furthermore, the air plug 63 is maintained in a state in which it is pressed from the inside to the outside of the housing 51 by the first tube 92 even after being fitted into the air socket 37, so that the air plug 63 can be firmly connected to the air socket 37.

[0101] As described above, in the process of mounting the part feeder 11 to the feeder base 23, the feeder side connector 64 and the cart side connector 38 are fitted together, and the engagement pin 39 on the feeder cart 12 side engages with the pin engagement hole 65H on the part feeder 11 side. This enables the supply of power from the component mounting unit 1B to the part feeder 11, and enables the mounting unit control device 17 to control the operation of the part feeder 11. The engagement of the engagement pin 39 with the pin engagement hole 65H restricts the lateral movement of the rear of the part feeder 11, and prevents the rear of the housing 51 from swaying laterally when the housing 51 is subjected to vibrations while mounted on the feeder base 23.

[0102] Also, just before the leading end of the housing 51 abuts against the feeder stopper 31 as described above, the hook-shaped member 61 of the parts feeder 11 and the lock pin 34c of the lock arm 34 of the feeder cart 12 engage with each other. Explaining this in detail, when the slider 55 is inserted into the feeder attachment portion 25 and the housing 51 is pushed forward (toward the back) (arrow A1 shown in FIG. 18(a)), first, the inclined surface 61a of the hook-shaped member 61 abuts against the operation pin 34b of the lock arm 34 from behind (FIG. 18(a)).

[0103] After the inclined surface portion 61a abuts against the operation pin 34b, when the housing 51 is further pushed backward, the inclined surface portion 61a of the hook-shaped member 61 pushes up the operation pin 34b. As a result, the lock arm 34 swings about the pivot shaft 34d while compressing the biasing spring 34e (arrow R1 shown in FIG. 18(b)), and then, when the operation pin 34b reaches above the base end side recessed portion 61c of the hook-shaped member 61, the state in which the operation pin 34b is pushed up by the inclined surface portion 61a is released. Therefore, the lock arm 34 swings to return to its original position by the restoring force of the biasing spring 34e (arrow R2 shown in FIG. 18(c)), and the operation pin 34b falls into the base end side recessed portion 61c of the hook-shaped member 61. At the same time, the lock pin 34c of the lock arm 34 falls into and engages with the tip end side recessed portion 61b of the hook-shaped member 61. This causes the parts feeder 11 to be locked to the feeder base 23.

[0104] In this embodiment, the hook-shaped member 61, which is a hook-shaped feeder-side engaging member provided on the parts feeder 11, is adapted to engage with the lock pin 34c, which is a cart-side engaging member provided on the feeder cart 12, by sliding it relative to the feeder base 23 of the feeder cart 12.

[0105] When the hook-shaped member 61 engages with the lock pin 34c as described above, the hook-shaped member 61 enters the guide passage 36 between two guide pieces 35 located corresponding to the lock pin 34c to be engaged, among the multiple guide pieces 35 provided on the feeder cart 12. At this time, both side surfaces of the hook-shaped member 61 are smoothly guided into the guide passage 36 by the tapered surfaces 35M provided on the two guide pieces 35.

[0106] The hook-shaped member 61 guided into the guide passage 36 has both sides guided by a pair of side surfaces (guide surfaces 35G) constituting the guide passage 36 (FIG. 19(a)→FIG. 19(b)), and even after engaging with the lock pin 34c, the hook-shaped member 61 is kept guided (supported) by the pair of guide surfaces 35G. Here, the distance KK (FIG. 5) between the pair of guide surfaces 35G is set to be slightly larger than the dimension in the thickness direction of the hook-shaped member 61, and the hook-shaped member 61 with both sides guided (supported) by the pair of guide surfaces 35G is prevented from being displaced in the lateral direction of the housing 51 (i.e., the part feeder 11). Therefore, even if the hook-shaped member 61 is subjected to a vibration force generated by the part feeder 11 performing a part feed operation, the lateral vibration of the housing 51 can be reduced. Therefore, the accuracy of the parts BH fed by the part feeder 11 to the part feed port 11K can be improved.

[0107] Thus, the part feeder 11 of the part supply unit 1A in this embodiment includes a hook-shaped member 61 that engages with the lock pin 34c provided on the feeder cart 12 side by sliding it relative to the feeder base 23, and the feeder cart 12 includes a plurality of guide pieces 35 arranged side by side in a lateral direction (X direction) that is a horizontal direction perpendicular to a front-rear direction (Y direction) in which the part feeder 11 slides relative to the feeder base 23. The hook-shaped member 61 engages with the lock pin 34c through a guide passage 36 between a pair of guide surfaces 35G that face each other in the lateral direction of two adjacent guide pieces 35 among the plurality of guide pieces 35, and the pair of guide surfaces 35G support both side surfaces of the hook-shaped member 61 before and after the hook-shaped member 61 engages with the lock pin 34c.

[0108] Therefore, even if the part feeder 11 is made thinner and the lateral displacement (in the direction of falling) of the housing 51 cannot be sufficiently prevented by simply fixing the front part of the housing 51 on which the slider 55 is provided to the feeder base 23, it is possible to suppress lateral shaking of the part feeder 11 relative to the feeder base 23. Furthermore, by suppressing lateral shaking of the housing 51, when the part feeder 11 is attached to the feeder base 23 by sliding, the air plug 63 and the feeder side connector 64 can be smoothly fitted into the air socket 37 and the cart side connector 38 on the feeder cart 12 side, respectively, and the engagement pin 39 can be smoothly engaged with the pin engagement hole 65H.

[0109] When removing part feeder 11 attached to feeder base 23, operator OP slides and pulls out part feeder 11 in the opposite direction to that in which part feeder 11 was attached to feeder base 23. Specifically, operator OP pulls backward operation knob 75 provided on the rear surface of part feeder 11 to be removed from feeder base 23 (arrow A2 shown in FIG. 20(a)).

[0110] When the operator OP pulls the operation knob 75 rearward, the slide member 74 connected to the operation knob 75 slides rearward within the slide space 51S and pulls the upper end side of the wire 77 rearward, so that the rear end of the lever member 72 connected to the lower end side of the wire 77 is pulled up (Fig. 13(a) → Fig. 13(b)). When the rear end of the lever member 72 is pulled up, the front part 72M of the lever member 72 pushes down the operated pin 62P of the lock release member 62, and the lock release member 62 swings in the front end raising direction about the front pivot pin 71, so that the operation pin 34b located in the base end side recess 61c of the hook-shaped member 61 is pushed up by the inclined surface 62a of the lock release member 62 (Fig. 13(a) → Fig. 13(b), Fig. 21(a) → Fig. 21(b)). As a result, the lock pin 34c moves upward out of the tip-side recess 61b of the hook-shaped member 61, and the engagement (lock) between the hook-shaped member 61 and the lock pin 34c is released (FIG. 21(a)→FIG. 21(b)).

[0111] When the engagement between the hook-shaped member 61 and the lock pin 34c is released as described above, the force of the operator OP pulling the operation knob 75 rearward moves the parts feeder 11 rearward on the feeder base 23. This causes the slider 55 to slide rearward inside the feeder mounting portion 25, and the positioning protrusion 56 slides inside the positioning groove 26M and disengages from the positioning groove 26M. In addition, the air plug 63 separates from the air socket 37, the feeder-side connector 64 separates from the cart-side connector 38, and the engagement pin 39 separates from the pin engagement hole 65H (FIG. 21(b) → FIG. 21(c)).

[0112] As described above, the slider 55 slides rearward within the feeder mounting portion 25, so that the rear slider 55b first comes off rearward from the feeder mounting portion 25 (FIG. 22(a)). At this point, the entire front slider 55a still remains within the feeder mounting portion 25, so the housing 51 maintains a substantially horizontal posture, but as the front slider 55a continues to slide rearward within the feeder mounting portion 25 and is about to come off the feeder mounting portion 25, the housing 51 tilts rearward downward (arrow B1 shown in FIG. 22(b)). Then, the rear end of the front slider 55a abuts against the positioning guide 26 from the front (FIGS. 22(b) and 20(b)), so that the housing 51 cannot be moved rearward any further, and the removal of the parts feeder 11 from the feeder base 23 (feeder mounting portion 25) is interrupted.

[0113] In this manner, the slider 55 of the part feeder 11 is provided with a cutout portion 55K at the middle portion in the sliding direction (Y direction) relative to the feeder base 23, and the feeder base 23 is provided with a positioning guide 26 as a stopper at the rear of the feeder mounting portion 25. The positioning guide 26 is adapted to come into contact with the rear end of the front slider 55a when the part feeder 11 is moved rearward from the state in which the slider 55 is attached to the feeder mounting portion 25, and the part feeder 11 is tilted in the direction in which the rear side of the part feeder 11 descends immediately before the front slider 55a of the slider 55 located forward of the cutout portion 55K comes out of the feeder mounting portion 25.

[0114] In order for the operator OP to completely pull out the part feeder 11 from the feeder attachment portion 25 when the pull-out of the part feeder 11 from the feeder base 23 has been interrupted as described above, the operator OP grasps the handle portion 51D provided on the housing 51 with the hand HD and lifts the upper rear portion of the housing 51 (arrow B2 shown in FIG. 23(a)) to bring the housing 51 into a horizontal position (FIG. 23(a)). Then, while grasping the handle portion 51D, the operator OP pulls the housing 51 horizontally backward (arrow A2 shown in FIG. 23(b)), and the part feeder 11 is completely pulled out from the feeder base 23.

[0115] In this embodiment, even if the operation knob 75 is pulled backward to simultaneously release the lock of the part feeder 11 relative to the feeder base 23 and pull the part feeder 11 out of the feeder base 23, the part feeder 11 stops moving backward before being completely pulled out of the feeder base 23. Therefore, when the part feeder 11 is removed from the feeder base 23, the part feeder 11 does not suddenly come out of the feeder base 23. Therefore, the part feeder 11 attached to the feeder cart 12 can be safely and easily removed with one hand. Furthermore, since the movement of the part feeder 11 is suspended, it becomes easier for the operator OP to work on the part feeder 11.

[0116] As described above, in the component supply device (component supply unit 1A) of this embodiment and the component mounting device 1 equipped with it, both side surfaces of the hook-shaped member 61 equipped on the part feeder 11 are guided by a pair of guide pieces 35 (a pair of guide surfaces 35G) equipped on the feeder cart 12, suppressing the lateral (falling) displacement of the part feeder 11. This makes it possible to reduce the lateral shaking of the part feeder 11, and to improve the supply accuracy of the parts BH to the component supply port 11K.

[0117] Although the embodiment of the present invention has been described above, the present invention is not limited to the above and various modifications are possible. For example, in the above embodiment, the parts feeder 11 is described as a tape feeder, but the parts feeder 11 is not limited to a tape feeder and may be a bulk feeder or the like. [Industrial Applicability]
