Description

Technical Field

[0001] The present invention relates to a component supply device consisting of a component feeder for supplying components and a feeder trolley for mounting the component feeder, as well as a component mounting device having the component supply device. Background Technology

[0002] Conventionally, component mounting devices for mounting components onto printed circuit boards or other components include a component supply unit (component supply device) and a component mounting section for mounting components supplied from the component supply unit onto the component mounting object. The component supply device consists of a component feeder for supplying components and a feeder carriage for mounting the component feeder. The component feeder has a slider on the lower surface of the front portion of its housing, and the feeder carriage has a feeder mounting section on the upper surface of a block-shaped feeder base for slidably mounting the slider (see, for example, Patent Document 1 below). The component feeder mounted on the feeder base is locked relative to the feeder base by engaging a hook-shaped feeder-side engaging member provided at the rear of the housing with a carriage-side engaging member provided on the feeder carriage side.

[0003] In a component supply device with such a structure, the component supply port of the component feeder is located at the front of the housing, and the slider located at the front of the slider is mounted on the feeder mounting part to hold the housing, thereby reducing the impact of lateral sway (displacement in the tilting direction) of the component feeder and helping to improve the component supply accuracy.

[0006] Patent Document 1: Japanese Patent Application Publication No. 2020-113594 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, as component feeders become thinner, as has been the case in recent years, it is difficult to prevent lateral swaying of the housing simply by holding the front of the housing to the feeder base, which may reduce the feeding accuracy of the components.

[0009] Therefore, the object of the present invention is to provide a component supply device capable of suppressing lateral swaying of a component feeder mounted on a feeder trolley, and a component mounting device having the component supply device.

[0010] Solution for solving the problem

[0011] The component supply device of the present invention includes a component feeder for supplying components and a feeder trolley having a feeder base for slidingly mounting the component feeder. The component feeder has a hook-shaped feeder-side engaging member, which engages with a trolley-side engaging member disposed on the side of the feeder trolley by sliding relative to the feeder base. The feeder trolley has a plurality of guide plates arranged laterally in a horizontal direction orthogonal to the front-back direction of the component feeder relative to the feeder base. The feeder-side engaging member engages with the trolley-side engaging member through a guide passage between a pair of opposing sides of two adjacent guide plates in the laterally lateral direction. The pair of opposing sides guide both sides of the feeder-side engaging member before and after engagement.

[0012] The component mounting device of the present invention includes the component supply device of the present invention described above, and a mounting head that picks up the component supplied by the component feeder of the component supply device and mounts it onto the component mounting object.

[0013] Invention Effects

[0014] According to the present invention, lateral swaying of the component feeder mounted on the feeder trolley can be suppressed. Attached Figure Description

Detailed Implementation

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This diagram illustrates a component mounting apparatus 1 according to one embodiment of the present invention. The component mounting apparatus 1 is an apparatus that repeatedly performs component mounting operations by mounting a component mounting object (e.g., a printed circuit board) KB, which is brought in from the upstream process side, onto a component mounting component BH, and then moving it out to the downstream process side. For ease of explanation, the horizontal direction along the transport direction of the component mounting object KB in the component mounting apparatus 1 is designated as the X direction, the horizontal direction orthogonal to the X direction is designated as the Y direction, and the vertical direction is designated as the Z direction. Furthermore, the X direction as observed from the operator OP is designated as the horizontal direction, the Y direction as observed from the operator OP is designated as the front-back direction, and the side farther from the operator OP in the front-back direction is designated as the front, and the side closer to the operator OP is designated as the rear.

[0041] exist Figure 1 In this component loading device 1, there are component supply section 1A for supplying component BH, and component loading section 1B for loading component BH supplied by component supply section 1A onto component loading object KB. Component supply section 1A includes component feeder 11 and feeder trolley 12, and component loading section 1B includes base 13, transport section 14, loading head 15, head moving mechanism 16, and loading section control device 17.

[0042] exist Figure 2 In the component supply unit 1A, the component feeder 11 has an overall shape that extends along the YZ plane. When the component feeder 11 is installed on the feeder trolley 12, it has a component supply port (component supply port 11K) on the upper front (inner side) as seen from the operator OP.

[0043] exist Figure 1 In this design, the feeder trolley 12 has a feeder base support 22 extending upward from the body section 21, which is movable on the ground FL. Above the feeder base support 22 is a block-shaped feeder base 23 for the component feeders 11 to be easily mounted and detached. Multiple component feeders 11 can be mounted on the feeder base 23 in an X-direction arrangement.

[0044] exist Figure 1 In this configuration, the transport section 14 of the component mounting section 1B consists of a pair of belt conveyors 14a, which extend along the X direction on the base 13. The transport section 14 transports the component mounting object KB sent from the upstream process side and positions it at a predetermined working position.

[0045] exist Figure 1In this assembly, the mounting head 15 has multiple suction nozzles 15N extending downwards. The mounting head 15 is capable of moving each suction nozzle 15N in the vertical direction and rotating each suction nozzle 15N about a vertical axis. The mounting head 15 is also capable of generating a suction force based on vacuum pressure at the lower end of each suction nozzle 15N. The head moving mechanism 16 is, for example, an XY stage mechanism, and moves the mounting head 15 along the horizontal plane (XY plane) in the region above the base 13.

[0046] exist Figure 1 Within the base 13, a mounting section control device 17 is installed. The mounting section control device 17 controls the operation of each part of the component mounting section 1B. Specifically, the mounting section control device 17 controls the transport and positioning of the component mounting object KB by the transport section 14, and controls the lifting, lowering, and rotating movements of each of the multiple suction nozzles 15N on the mounting head 15. The mounting section control device 17 also causes the lower end of each suction nozzle 15N to generate an adsorption force on the component BH, thereby activating the head moving mechanism 16 and moving the mounting head 15.

[0047] When the component mounting device 1 is performing component mounting operations, firstly, the transport unit 14 receives and transports the component mounting object KB sent from the upstream process side, and positions the component mounting object KB in the working position. After positioning the component mounting object KB in the working position, the head moving mechanism 16 is activated, thereby moving the mounting head 15 above the component feeder 11, so that multiple suction nozzles 15N respectively adsorb component BH.

[0048] After the multiple suction nozzles 15N have each picked up a component BH, the mounting head 15 is moved upwards above the component mounting object KB. Then, the suction nozzles 15N are lowered above the target mounting position set on the component mounting object KB, and the component BH is mounted at the target mounting position. After repeatedly performing this operation of the mounting head 15 to mount all the components BH that should be mounted on the component mounting object KB, the transport unit 14 operates to move the component mounting object KB to the downstream process side. Thus, the component mounting operation of one component mounting object KB performed by the component mounting device 1 is completed.

[0049] In this component loading device 1 with such a structure, the component feeder 11 and the feeder trolley 12 constituting the component supply unit 1A have structural features, which will be described below.

[0050] First, the feeder trolley 12 will be described. Figure 2 as well as Figure 3In the feeder trolley 12, a platform-shaped portion 23D is formed in the front region (the inner region observed from the operator OP) of the upper surface of the feeder base 23, with its upper surface positioned higher than the rear region (the region near the front observed from the operator OP) of the feeder base 23. Multiple feeder mounting members 24 are arranged at intervals along the X-direction on the platform-shaped portion 23D.

[0051] Each feeder mounting component 24 is composed of a rod-shaped member with a "T"-shaped cross-section extending along the Y direction. The space between two adjacent feeder mounting components 24 is an "inverted T" shape with the top and bottom of the "T" reversed. Hereinafter, this space will be referred to as the feeder mounting section 25.

[0052] exist Figure 2 as well as Figure 3 In this configuration, a positioning guide 26 is installed in the rear region of the upper surface of the feeder base 23. Also, as... Figure 4 As shown, the positioning guide 26 is composed of a plate-shaped member extending laterally (X direction). Multiple wall portions 26F are provided on the upper surface of the positioning guide 26 in a manner arranged along the X direction at constant intervals. Positioning grooves 26M are formed between adjacent wall portions 26F for engagement with positioning protrusions 56 of the component feeder 11, which will be described later. Thus, the positioning guide 26 has a structure with multiple positioning grooves 26M arranged along the X direction on its upper surface side. Figure 4 ).

[0053] exist Figure 4 In the positioning guide 26, screw insertion holes 26H are provided on the bottom surface of two positioning grooves 26M located at both ends of the positioning guide 26. Two other positioning grooves 26M, different from those with screw insertion holes 26H, have protruding engagement holes 26K on their bottom surfaces. Two aligning protrusions 23T are provided on the upper surface of the feeder base 23, protruding upwards, to engage with the two protruding engagement holes 26K of the positioning guide 26. Threaded holes 23H are provided at two positions corresponding to the two screw insertion holes 26H when the two aligning protrusions 23T are engaged with the two protruding engagement holes 26K. Figure 4 ).

[0054] For the operation of mounting the positioning guide 26 onto the upper surface of the feeder base 23, firstly, the two protruding engagement holes 26K of the positioning guide 26 are inserted into the two alignment protrusions 23T of the feeder base 23, thereby positioning the positioning guide 26 in a state of being positioned on the upper surface of the feeder base 23. After the two screw through holes 26H on the positioning guide 26 side are aligned with the two threaded holes 23H on the feeder base 23 side, screws 27 are inserted into the two screw through holes 26H respectively, and the screws 27 are screwed into the corresponding threaded holes 23H. Thus, the positioning guide 26 is mounted on the upper surface of the feeder base 23 in a state where it is accurately positioned relative to the feeder base 23 by the alignment protrusions 23T.

[0055] Here, screw 27 is, for example, a countersunk screw. With screw 27, having passed through screw insertion hole 26H, screwed into threaded hole 23H, the upper surface of the screw head is at the same height as the bottom surface of the positioning groove 26M of the positioning guide 26, or at a height lower than the bottom surface of the positioning groove 26M. Furthermore, the upper end of the alignment protrusion 23T, which engages with the protrusion engagement hole 26K, does not protrude upwards from the protrusion engagement hole 26K (i.e., it is located at a position lower than the bottom surface of the positioning groove 26M).

[0056] exist Figure 2 as well as Figure 5 In this embodiment, multiple feeder mounting portions 25 arranged laterally (X-direction) on the feeder base 23 form a groove 28 with a positioning guide 26 corresponding to each feeder mounting portion 25. That is, the feeder base 23 has a structure with multiple grooves 28 arranged in the X-direction on its upper surface. In this embodiment, there are two positioning guides 26 mounted on the upper surface of the feeder base 23, and the multiple positioning grooves 26M on the upper surface of the feeder base 23 are separately disposed on the two positioning guides 26.

[0057] In this embodiment, multiple positioning slots 26M are arranged in a horizontal direction (X direction) orthogonal to the sliding direction (Y direction) in which the component feeder 11 slides relative to the feeder base 23, resulting in a single positioning guide 26 having multiple positioning slots 26M. Furthermore, the multiple positioning slots 26M on the feeder base 23 are also arranged as multiple (here, two) positioning guides 26 separately on the upper surface of the feeder base 23.

[0058] In this embodiment, the positioning guide 26 is detachable from the feeder base 23 by means of a screw 27 that passes through the bottom surface of the positioning groove 26M and is screwed into the feeder base 23. When the positioning guide 26 is installed on 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.

[0059] exist Figure 2 as well as Figure 3 In the feeder base 23, a feeder limiter 31 is provided at the front end (the inner side as observed from the operator OP). The feeder limiter 31 has a shape that extends along the XZ plane and upwards. The upper and lower parts of the feeder limiter 31 are respectively provided with an upper pin insertion hole 31A and a lower pin insertion hole 31B in a configuration corresponding to each slot 28.

[0060] exist Figure 2 , Figure 3 as well as Figure 6 In (a) and (b), a protruding member 32 is provided on the lower surface of the rear part (near the front side observed from the operator OP) of the feeder base 23, extending downward and towards the rear of the feeder base 23. A bracket 33 having a shape that extends integrally along the XZ plane and downward is provided at the rear of the protruding member 32.

[0061] exist Figure 2 , Figure 3 as well as Figure 6 In (a) and (b), a plurality of locking arms 34 are arranged in the X direction at the rear end of the protruding member 32 in a configuration corresponding to each slot 28. Figure 7 As shown, the locking arm 34 includes a pair of arm plates 34a that are arranged opposite each other in the X direction and extend in the front-rear direction (Y direction), and an operating pin 34b and a locking pin 34c that are disposed between the pair of arm plates 34a and extend in the X direction.

[0062] exist Figure 3 In the feeder base 23, a plurality of hook-shaped portions 23K are arranged in a manner along the X direction at the rear end. Regarding the hook-shaped portions 23K, as... Figure 6 (a) and Figure 7 As shown, the front ends of a pair of arm plates 34a are pivotally supported by a pivot support shaft 34d extending in the X direction. The two ends of the operating pin 34b are supported at the rear ends of the pair of arm plates 34a in the front-rear direction. The two ends of the locking pin 34c are supported at the middle portion of the pair of arm plates 34a in the front-rear direction. The portion of the locking arm 34 forward of the pivot support shaft 34d is subjected to an upward force by a force-applying spring 34e.

[0063] exist Figure 2 , Figure 3 as well as Figure 6In (a) and (b), a plurality of guide plates 35 are provided below the plurality of locking arms 34 that extend from the rear end face of the member 32 and are arranged in the X direction, in a transverse (X direction) arrangement. Each guide plate 35 has a rearward protruding shape, and a guide passage 36 is formed between a pair of side faces (referred to as "guide surfaces 35G") that are opposed in the transverse (X direction) direction of two adjacent guide plates 35.

[0064] In this embodiment, the feeder trolley 12 has a plurality of guide plates arranged in a horizontal direction (X direction) orthogonal to the front-back direction (Y direction) of the component feeder 11 relative to the feeder base 23. The guide plates 35 are arranged such that adjacent guide plates 35 face to face in the horizontal direction, forming a guide passage 36. Figure 5 As shown, the portion that connects to the rear of each of the two guide surfaces 35G becomes a cone surface 35M that extends rearward in a cone shape.

[0065] exist Figure 2 , Figure 3 as well as Figure 6 In (a), an air inlet 37 is provided at the rear end of the protruding member 32. A trolley-side connector 38 and a locking pin 39 are provided on the upper part of the bracket 33, which is detachable from the protruding member 32.

[0066] exist Figure 2 , Figure 3 as well as Figure 6 In (a), the air inlet 37, the trolley-side connector 38, and the locking pin 39 are arranged sequentially from top to bottom, and each protrudes rearward. The air inlet 37, the trolley-side connector 38, and the locking pin 39 are arranged in the X direction, and a group of one air inlet 37, one trolley-side connector 38, and one locking pin 39 arranged in the vertical direction is arranged to correspond to the multiple slots 28 respectively.

[0067] Air inlet 37 is connected to an air pipe inside the component mounting section 1B that supplies air from an external air supply source (not shown). Carriage-side connector 38 is connected to a cable inside the component mounting section 1B that supplies power from an external power source (not shown).

[0068] exist Figure 2 , Figure 3 as well as Figure 6In (a), a trolley-side control board 41, serving as a control board for the feeder trolley 12, is installed in the area on the front (inner) side of the bracket 33. Specifically, the trolley-side control board 41 is mounted on the bracket 33 in a longitudinal orientation with its thickness direction (relative to the surface normal NR) toward the sliding direction (the direction in which the component feeder 11 slides relative to the feeder base 23, the direction of extension of the feeder mounting member 24, the Y direction) of the sliding direction of the component feeder 11 relative to the feeder base 23.

[0069] In this embodiment, the trolley-side control board 41 of the feeder trolley 12 is arranged in a longitudinal orientation rather than the conventional transverse orientation, thus shortening the dimension of the feeder base 23 in the longitudinal direction (Y direction) and making the feeder trolley 12 more compact overall.

[0070] exist Figure 6 In (a), multiple trolley-side connectors 38 are electrically connected to the trolley-side control board 41 via trolley-side wiring 41C. That is, the trolley-side control board 41 is configured as a unit (control board unit 41U) that is integrated with the trolley-side connectors 38 and the bracket 33.

[0071] As mentioned above, the bracket 33 is detachable from the protruding member 32 of the feeder base 23. Therefore, by removing the bracket 33 from the feeder base 23, the entire control board unit 41U, including the trolley-side control board 41 and the trolley-side connector 38, can be removed from the feeder base 23. Thus, maintenance of the trolley-side control board 41 and the trolley-side connector 38 can be performed very easily.

[0072] exist Figure 6 In (a) and (b), a floating mechanism 43 is provided between the feeder base support 22 and the feeder base 23 of the feeder trolley 12. The floating mechanism 43 supports the feeder base 23 in a reference posture such that the upper surface of the feeder base 23 is approximately horizontal (floating support). The floating mechanism 43 is configured to have a fixed side member 43a provided at the upper end of the feeder base support 22 and a movable side member 43b located above the fixed side member 43a and connected to the feeder base 23.

[0073] The feeder base 23 (fixed side member 43a) is in a horizontal position (reference position) when it is in its natural state without any external force in the vertical direction other than its own weight, and it abuts against the upper surface of the movable side member 43b. However, when an external force is applied, it tilts from the reference position. 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 side member 43b) is in a downward position. Conversely, when a downward external force is applied to the rear end of the feeder base 23, the feeder base 23 tilts from the reference position.

[0074] In this embodiment, the feeder trolley 12 has a floating mechanism 43, which is clamped between the feeder base 23 and the feeder base support portion 22 that supports the feeder base 23 from below, and provides floating support for the feeder base 23.

[0075] exist Figure 6 In (a) and (b), an abutting member 44 is provided on the lower surface of the feeder base 23, protruding downwards. On the other hand, an abutting member 45 is provided on the upper surface of the fixed-side member 43a constituting the floating mechanism 43, protruding upwards. Figure 6 As shown in (a), the abutting member 44 is composed of a groove-shaped cross-section member extending laterally (X direction), and multiple members are arranged laterally. The fixed side member 43a is also composed of a groove-shaped cross-section member extending laterally (X direction).

[0076] The abutting member 44 abuts against the abutting member 45 from above when the feeder base 23 is in a reference position (see reference). Figure 6 The standard contact point T0 is shown in (a) and (b). Therefore, the feeder base 23 cannot be easily tilted even if it is desired to tilt from the reference posture in the direction that lowers the front end (tilt forward).

[0077] In this embodiment, the abutting member 44, which is a base-side member protruding downward from the lower surface of the feeder base 23, and the abutting member 45, which is a support-side member provided on the feeder base support 22 (directly on the fixed-side member 43a) supporting the feeder base 23 and abutting the abutting member 44, become a tilting limiting member 46 that limits the range of tilting motion of the feeder base 23 from a generally horizontal reference posture to the direction that causes the front end to drop.

[0078] When an external force is applied that forcibly tilts the feeder base 23 forward from a state where the feeder base 23 is in a state where the forward tilt of the feeder base 23 is restricted from its reference posture due to the contact member 44 and the contacted member 45 contacting each other, the feeder base 23 tilts forward with the contact point T1, which is forward of the standard contact point T0, as the fulcrum. It should be noted that in this case, the forward tilt is also restricted up to the tilting limiter (forward tilting limiter 47) provided on the movable side member 43b. Figure 6 (a)) within the range where the feeder base 23 cannot tilt further forward after contacting the fixed side member 43a. Figure 8 (a)

[0079] In this embodiment, the feeder trolley 12, in addition to having a floating mechanism 43 that is sandwiched between the feeder base support 22 and the feeder base 23 and floats to support the feeder base 23, also has a tilting limiting part 46 that limits the range of motion of the feeder base 23 tilting forward from a generally horizontal reference posture toward a direction that lowers the front end. Therefore, the feeder base 23 is in a state where it is floated and supported by the floating mechanism 43 while being limited to tilting forward from a generally horizontal reference posture by the tilting limiting part 46. Even if the center of gravity of the feeder base 23 is located in front due to the compactness of the feeder base 23, the feeder base 23 is prevented from tilting forward due to its own weight.

[0080] On the other hand, when an external force acts on the feeder base 23 in the reference posture in the direction of rear-end descent, the feeder base 23 tilts backward under the action of this external force. Furthermore, when the tilt angle from the reference posture reaches a certain amount, it comes into contact with the rear end 43E of the fixed-side member 43a from above. And, in this way, when an external force acts on the feeder base 23 in the direction of rear-end descent of the fixed-side member 43a (…),… Figure 8 When the feeder base 23 is further tilted backward by an external force in the state of contact (b), the feeder base 23 abuts at the rear end 43E of the fixed side member 43a at the contact point (the contact point T2 when tilted backward). Figure 8 (b) is the fulcrum tilt. It should be noted that in this case, the tilt is also limited up to the tilt limiting limiter (tilt limiting limiter 49) provided on the fixed side member 43a. Figure 6 (a)) within the range where the feeder base 23 cannot tilt further backward and abuts against the movable side member 43b. Figure 8 (b)

[0081] In this embodiment, the feeder trolley 12 has a tilting limiter that limits the range of motion of the feeder base 23 tilting backward from a reference posture toward a direction that lowers the rear end.

[0082] Next, the component feeder 11 will be described. Figure 9 as well as Figure 10 In (a) and (b), the component feeder 11 has a thin housing 51 with a small transverse (X-direction) dimension. Inside the housing 51 is a component supply mechanism (not shown) that transports the carrier belt CT from the rear of the housing 51 toward the component supply port 11K located at the upper front of the housing 51, and a handle portion 51D is provided at the upper rear of the housing 51.

[0083] exist Figure 2 , Figure 9 as well as Figure 10 In (a), the downwardly protruding portion (a part of the housing 51) at the rear of the housing 51 becomes the downward extension 52. In this embodiment, as... Figure 1 As shown, the component feeder 11 is conceived as a belt feeder that pulls the carrier belt CT containing the component BH from the reel RL and transports it to the component supply port 11K to supply the component BH. However, the component feeder 11 is not limited to a belt feeder, and can also be a bulk feeder or a rod feeder, etc.

[0084] exist Figure 9 as well as Figure 10 In (a) and (b), an upper pin 53 and a lower pin 54, which are two positioning pins, are provided at the front end of the housing 51, respectively, protruding forward. A slider 55 is provided at the front part of the housing 51 in the front-rear direction (Y direction), extending along the lower surface of the housing 51, and a positioning protrusion 56 is provided at the middle part of the housing 51 in the front-rear direction, protruding downward.

[0085] The slider 55 has an inverted T-shaped cross-sectional shape in the space (the aforementioned feeder mounting portion 25) formed between adjacent feeder mounting members 24 that are provided on the upper surface of the feeder base 23 (specifically, the platform-shaped portion 23D). For example... Figure 2 , Figure 9 as well as Figure 10 As shown in (a) and (b), the slider 55 has a notch 55K in the middle part of the housing 51 in the front-back direction (Y direction), that is, the sliding direction relative to the feeder base 23. The slider 55 is divided into a part located in front of the notch 55K (front slider 55a) and a part located behind the notch 55K (rear slider 55b).

[0086] In this embodiment, a notch 55K is provided in the middle of the sliding direction (Y direction) of the slider 55 of the component feeder 11 relative to the feeder base 23, and is composed of a front slider 55a located in front of the notch 55K and a rear slider 55b located behind the notch 55K.

[0087] exist Figure 2 , Figure 9 as well as Figure 10 In (a) and (b), the positioning protrusion 56 is composed of a cylindrical pin member. The positioning protrusion 56 is positioned on the extension line of the slider 55, that is, along the center line of the Y-axis of the slider 55.

[0088] exist Figure 9 , Figure 10 (a) and Figure 11 In the lower extension 52, a hook-shaped member 61, a locking release member 62, an air plug 63, a feeder-side connector 64, and a base plate member 65 are provided. The hook-shaped member 61, the locking release member 62, the air plug 63, and the feeder-side connector 64 are respectively configured to protrude forward from the front surface of the lower extension 52.

[0089] exist Figure 10 (a) and Figure 11 In this context, the hook-shaped member 61 is a component feeder-side engagement member (feeder-side engagement member) that engages with the aforementioned locking pin 34c, which serves as the engagement member on the trolley side (trolley-side engagement member). It is composed of a plate-shaped member extending along the YZ plane. The base end of the rear end of the hook-shaped member 61 is fixed relative to the housing 51 (specifically, the lower extension 52).

[0090] exist Figure 11 as well as Figure 12 In this design, the upper edge of the hook-shaped member 61 forms an upward-sloping portion 61a extending from the front end (tip) towards the rear. A front end recess 61b with an upward opening is provided at the front end of the hook-shaped member 61, and a base end recess 61c with a similar upward opening is provided at the base end of the hook-shaped member 61. The upper edge of the rear side of the front end recess 61b and the upper edge of the front side of the base end recess 61c are connected to the sloped portion 61a.

[0091] exist Figure 11 In this configuration, the locking release member 62, like the hook member 61, is composed of a plate-like member along the YZ plane and is positioned to the side of the hook member 61. Also as... Figure 12 As shown, the upper surface (upper edge) of the locking release member 62 becomes an inclined surface 62a that decreases in height from the rear to the front.

[0092] exist Figure 12 as well as Figure 13In (a) and (b), the middle portion of the locking release member 62 is pivotally supported by a front pivot support pin 71 located within the lower extension 52. Therefore, the locking release member 62 can swing freely in the plane along the YZ plane with the front pivot support pin 71 as its center, and can be positioned at a reference position that is approximately horizontal. Figure 13 (a) and the locked-out position of the attitude at which the front end (tip) is lifted from the reference position. Figure 13 Move between (b) and (b).

[0093] exist Figure 11 as well as Figure 12 In the lower extension 52, a rod member 72 is provided at a position behind the locking release member 62. The rod member 72 is a plate-shaped member extending along the Y direction, and its middle part is pivotally supported by a rear pivot support pin 73 located in the lower extension 52. Therefore, the rod member 72 can swing freely in the plane along the YZ plane with the rear pivot support pin 73 as the center, and can reach a first position where the rear part is lowered and the front part 72M is raised. Figure 13 (a) and the second position that raises the rear and lowers the front 72M ( Figure 13 Move between (b) and (b).

[0094] exist Figure 10 (a) and Figure 13 In (a) and (b), a sliding space 51S is provided at the upper rear part of the housing 51, which is formed in a manner extending in the Y direction. A sliding member 74, which is shaped to extend in the Y direction, is inserted into the sliding space 51S from the rear side of the housing 51.

[0095] The sliding member 74 can slide freely along the Y direction within the sliding space 51S, and can be located in the foremost non-operating position within the sliding space 51S. Figure 13 (a) and the operating position located at the rearmost position within the sliding space 51S ( Figure 13 The sliding member 74 moves between (b) and (c). When in the non-operating position, the sliding member 74 abuts against the inner wall 51N within the housing 51 forming the sliding space 51S from the rear. Figure 13 (a) protrudes rearward from the housing 51 when in the operating position. Figure 13 (b)

[0096] exist Figure 9 as well as Figure 10 In (a), an operating handle 75 is mounted on the rear end of the sliding member 74. The operating handle 75 is pivotally supported at its base end on the sliding member 74 via a handle pivot support pin 75P, and can swing freely in the plane along the YZ plane about the handle pivot support pin 75P. The operating handle 75 can be stored in a position where its front end is above the base end (see reference). Figure 13(a) shows the operating handle 75 (shown in solid line) and the usage position where the front end is located behind the base end (see reference). Figure 13 The operation shown in (a) with a single-dot dashed line is moving between the pinch hands 75).

[0097] exist Figure 10 (a) and Figure 13 In (a) and (b), a pulley 76 is provided in front of the sliding member 74 inside the housing 51. One end (upper end) of the cable 77 is connected to the rear end of the sliding member 74, and the other end (lower end) of the cable 77 is mounted to the rear end of the rod member 72 via the pulley 76. Figure 10 (a) and Figure 13 (a)(b)).

[0098] like Figure 13 As shown in (a), when the operating handle 75 is not operated by the operator (OP), the sliding member 74 is in a non-operational position with its front end abutting against the inner wall 51N of the housing 51, and the lever member 72 is in a first position with the front part 72M raised. The front part 72M of the lever member 72 abuts against the operated pin 62P, which is provided at the rear end of the locking release member 62 and protrudes in the X direction, from above, but the lever member 72 does not press down the operated pin 62P, and the locking release member 62 is in a reference position with a roughly horizontal posture. Furthermore, the front end recess 61b and the base end recess 61c of the hook member 61 are exposed above the inclined surface 62a of the locking release member 62 when viewed from the side. Figure 13 (a)

[0099] As described above, when the operating handle 75 is pulled backward from its inactive state by the operator (OP) Figure 13 (a)→ Figure 13 (b) The sliding member 74 moves to the operating position by protruding rearward from the housing 51, and the rear end of the rod member 72 is lifted via the cable 77. Thus, the rod member 72 swings around the rear pivot support pin 73 and is in the second position (b). Figure 13 (b) In the locking release member 62, the operated pin 62P is pressed down by the front part 72M, so the locking release member 62 swings around the front pivot support pin 71 and is in the locked-out position. When the locking release member 62 is in the locked-out position, the front end recess 61b and the base end recess 61c of the hook member 61 are respectively hidden below the inclined surface 62a of the locking release member 62 when viewed from the side. Figure 13 (b)

[0100] When the operator (OP) pulls the lever 75 backward, the lever member 72 returns to its first position due to its own weight, and the pressed pin 62P of the locking release member 62 is released. Thus, the locking release member 62 returns to its reference position, which is approximately horizontal, due to its own weight. Figure 13 (b)→ Figure 13 (a) The sliding member 74 is pulled back to the non-operating position by the cable 77. Figure 13 (a)

[0101] like Figure 11 , Figure 12 as well as Figure 14 As shown, a plate member 81 is provided on the front surface side of the lower extension 52. The plate member 81 is composed of a generally rectangular plate-shaped member extending in the vertical direction. A gas plug 63, which is installed through the middle of the plate member 81 along the thickness direction of the plate, is held in the middle of the plate member 81 in a state where it is fastened by two fixing nuts 81N. Figure 11 as well as Figure 14 The air plug 63 is a connector component (feeder-side connector component) on the component feeder 11 side of an air connector formed between the feeder carriage 12 and the component feeder 11 mounted on the feeder carriage 12.

[0102] exist Figure 11 , Figure 12 as well as Figure 14 In this configuration, the upper and lower ends of the plate member 81 are mounted to the front surface of the lower extension 52 by two stepped bolts 82 (upper stepped bolt 82a and lower stepped bolt 82b). As a result, one end 63a of the air plug 63, which is held in the middle by the plate member 81, is located inside the housing 51, while the other end 63b of the air plug 63 is located outside the housing 51 (in front of the lower extension 52).

[0103] Here, the plate member 81 is held in place by an air plug retainer 83 consisting of the plate member 81 and two stepped bolts 82. Figure 11 , Figure 12 as well as Figure 14 It is installed in a state that allows it to move relative to the front surface of the lower extension 52 (i.e., the outer surface of the housing 51). For a detailed description, it is as follows... Figure 15As shown in (a), (b), and (c), bolt insertion portions 84 (upper bolt insertion portion 84a and lower bolt insertion portion 84b) are respectively provided at the upper and lower positions of the plate member 81, that is, at the upper and lower positions of the holding portion that holds the air plug 63. At the upper and lower bolt insertion portions 84, two stepped bolts 82 (upper stepped bolt 82a and lower stepped bolt 82b) are respectively screwed into the bolt holes 51H provided in the upper and lower plate holding portions 51T of the member serving as the housing 51 side. Here, the height dimension of the ring portion 82C of the stepped bolt 82, which is a non-threaded portion, is greater than the thickness dimension of the plate member 81. Figure 15 Therefore, plate member 81 can move within the height range of the ring portion 82C of stepped bolt 82.

[0104] In this embodiment, the component feeder 11 includes: an air plug 63 serving as a feeder-side connector member, which is a connector member on the component feeder 11 side forming an air connector with the feeder carriage 12 on which the component feeder 11 is slidably mounted; and an air plug holding portion 83 serving as a feeder-side connector member holding portion, which holds the air plug 63 in a horizontal and freely movable state relative to the housing 51 of the component feeder 11. Furthermore, the air plug holding portion 83 includes: a plate member 81 on which the air plug 63 is mounted; and a plurality of stepped bolts 82 serving as plate member mounting members, which mount the plate member 81 relative to the housing 51 of the component feeder 11 in a movable state and hold the air plug 63 in a substantially horizontal position, with two stepped bolts 82 passing through two bolt insertion portions 84 located above and below the portion of the plate member 81 on which the air plug 63 is mounted.

[0105] When the plate member 81 is mounted on the front surface of the lower extension 52 (i.e., the outer surface of the housing 51), firstly, the plate member 81 is tilted 90° to make it extend laterally. Figure 15 (a)). Then, the upper bolt insertion portion 84a is made to engage laterally with the ring portion 82C of the upper stepped bolt 82a. Figure 15 (b) Then, using the upper stepped bolt 82a as a fulcrum, the plate member 81 is rotated 90° by lowering the lower end of the plate member 81. Then, the lower bolt insertion part 84b engages with the ring part 82C of the lower stepped bolt 82b. Thus, the plate member 81 is mounted on the housing 51. Figure 15 (c)).

[0106] In this embodiment, the plate member 81 is configured such that one of the two bolt insertion portions 84 (here, the upper bolt insertion portion 84a) is open at the upper edge of the plate member 81, while the other of the two bolt insertion portions 84 (here, the lower bolt insertion portion 84b) is open at the side edge of the plate member 81. Therefore, when the plate member 81 is installed in the housing 51, it can be done with the two stepped bolts 82 respectively screwed into the plate holding portion 51T of the housing 51.

[0107] It should be noted that in this embodiment, the upper bolt insertion portion 84 opens at the upper edge of the plate member 81, while the lower bolt insertion portion 84 opens on the side of the plate member 81. However, it is also possible that the lower bolt insertion portion 84 opens at the lower edge of the plate member 81, while the upper bolt insertion portion 84 opens at the side edge of the plate member 81. That is, it is sufficient that one of the two bolt insertion portions 84 provided by the plate member 81 opens at the upper 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.

[0108] exist Figure 12 as well as Figure 14 Inside the housing 51, there is a valve unit 91 for air control and two pipes (first pipe 92 and second pipe 93) for air piping. The first pipe 92 and the second pipe 93 are made of elastomers such as rubber and are capable of bending and deformation.

[0109] One end (lower end) of the first tube 92 is connected to one of the two air piping connection ports protruding upward from the valve unit 91, namely the first connection port 91a, and the other end (upper end) is connected to one end 63a of the air plug 63. That is, the first tube 92 is disposed inside the housing 51 and becomes an air piping pipe made of an elastic body. One end of the first tube 92 is connected to the first connection port 91a, which is located inside the housing 51 and serves as an air piping connection port, and the other end is connected to one end 63a of the air plug 63, which serves as a feeder-side connector component.

[0110] On the other hand, for the second pipe 93, one end (lower end) is connected to the other of the two air piping connection ports of the valve unit 91, namely the second connection port 91b, and the other end (upper end) is connected to an air working device (not shown) installed in the housing 51 and operating by receiving air supply. The air introduced into the first pipe 92 through the air plug 63 is controlled in the valve unit 91 and sent to the air working device through the second pipe 93.

[0111] In this embodiment, such as Figure 14 As shown, the first connection port 91a faces upwards in the figure, and one end of the air plug 63 faces to the left. The first tube 92, with one end connected to the first connection port 91a and the other end mounted to one end of the air plug 63, functions to draw water from... Figure 14 The state shown by the dashed line is restored to the state shown by the solid line in an elastic restoring force configuration within the housing 51. That is, the first tube 92 is configured such that the elastic restoring force of the first tube 92 near the end (one end) connected to the first connection port 91a has a component in the direction of pressing the air plug 63 from the inside of the housing 51 toward the outside.

[0112] Here, the air plug 63 is held horizontally relative to the housing 51 and is movable by the air plug retainer 83, which is composed of a plate member 81 and two stepped bolts 82, and from Figure 14 or Figure 15 As can be seen from (a), (b), and (c), the length of the other end located outside the housing 51 is greater than the length of the end located inside the housing 51. Therefore, due to its own weight, the air plug 63 is in a descending posture with the front end descending on the side located outside the housing 51.

[0113] 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, pressing the upper and lower ends of the plate member 81 against the heads of the two stepped bolts 82 from the inside, thereby maintaining a horizontal posture. In this way, with the upper and lower ends of the plate member 81 pressed against the heads of the two stepped bolts 82 from the inside by the first tube 92, the air plug 63 held in the plate member 81 is kept in a horizontal posture in a floating state due to the elasticity of the first tube 92.

[0114] In this embodiment, the component feeder 11 includes: an air plug holding part 83 (plate member 81 and two stepped bolts 82) serving as a feeder-side connector member holding part, which holds the air plug 63 in a horizontal and movable state relative to the housing 51, such that one end 63a of the air plug 63 is located inside the housing 51 and the other end 63b of the air plug 63 is located outside the housing 51; and a first pipe 92 serving as an air piping pipe, which is made of an elastic body and is disposed inside the housing 51, with one end connected to a first connection port 91a located inside the housing 51 as an air piping connection port, and the other end connected to one end 63a of the air plug 63, such that the air plug 63 is pressed from the inside of the housing 51 to the outside by the first pipe 92.

[0115] Therefore, in the component feeder 11 of this embodiment, even if the protrusion of the air plug 63 towards the outside of the housing 51 is large, the situation where the air plug 63 descends relative to the housing 51 due to its own weight is prevented. This ensures that when installed on the feeder carriage 12, the air plug 63 can smoothly fit into the air inlet 37 on the feeder carriage 12 side. It should be noted that when the first tube 92 is configured to press the air plug 63 from the inside of the housing 51 towards the outside, the larger the outer diameter of the first tube 92, the greater the force FC exerted by the first tube 92 on the air plug 63. Furthermore, the longer the length of the first tube 92, the greater the force FC exerted by the first tube 92 on the air plug 63.

[0116] exist Figure 12 In the lower extension 52, a feeder-side control board 94 is provided behind the valve unit 91. The feeder-side control board 94 has the function of controlling the operation of various parts of the component feeder 11. The feeder-side control board 94 is electrically connected to the feeder-side connector 64 through the feeder internal wiring 95. The feeder-side connector 64 is an electrical connector on the component feeder 11 side that is electrically coupled to the feeder carriage 12.

[0117] exist Figure 12 In this configuration, a base plate member 65 extends along the Y direction on the lower surface of the lower extension 52. The front end portion of the base plate member 65 protrudes forward beyond the lower extension 52, and this protruding portion extends upward in a curved manner to form a curved portion 65K. A pin engagement hole 65H is provided in the curved portion 65K, penetrating the base plate member 65 along the plate thickness direction (Y direction).

[0118] When the component feeder 11 with such a structure is installed on the feeder base 23 of the feeder trolley 12, the operator (OP) inserts the slider 55 (front slider 55a and rear slider 55b) of the component feeder 11 into the feeder mounting part 25 of one of the multiple slots 28 selected from the rear direction of the feeder base 23, and pushes the housing 51 of the component feeder 11 forward (inward). Figure 16 Arrow A1 is shown in (a). Thus, firstly, the front slider 55a moves rearward within the feeder mounting portion 25 of the slot 28, and then the rear slider 55b moves rearward within the feeder mounting portion 25.

[0119] When the rear slider 55b of the component feeder 11 travels within the feeder mounting portion 25 as described above, the upper and lower positioning pins (upper pin 53 and lower pin 54) located at the front end of the housing 51 are inserted into the upper and lower pin insertion holes (upper pin insertion hole 31A and lower pin insertion hole 31B) provided in the feeder limiter 31, and the front end of the component feeder 11 abuts against the feeder limiter 31. Figure 16(b)). Thus, positioning of the front part of the housing 51 in the front-rear direction (Y direction) is performed. Furthermore, when the slider 55 travels within the feeder mounting portion 25, the positioning protrusion 56, located at the middle part of the housing 51 in the front-rear direction, enters from the rear into the positioning groove 26M located at the rear of the feeder mounting portion 25 and engages. Figure 16 (b)

[0120] Figure 17 Figure (a) is a view taken from the rear of the feeder trolley 12, showing the slider 55 mounted on the feeder mounting section 25. As can be seen from this figure, the lower surface of the slider 55 within the feeder mounting section 25 is separated from the upper surface of the feeder base 23. The front of the housing 51 is positioned laterally (X-direction) because the sides of the slider 55 are clamped by two adjacent feeder mounting members 24 forming the feeder mounting section 25, and is positioned in the height direction (Z-direction) because the lower pin 54 is inserted into the lower pin insertion hole 31B and the positioning protrusion 56 is inserted into the positioning groove 26M, as described above. It should be noted that in this state, the lower surface of the housing 51 is separated from the upper surface of the feeder mounting member 24, and the lower surface of the slider 55 is separated from the upper surface of the feeder base 23 (specifically, the upper surface of the platform-shaped portion 23D). Figure 17 (a)

[0121] Figure 17 (b) is a view taken from the rear of the feeder trolley 12, showing the positioning protrusion 56 engaged in the positioning groove 26M. As can be seen from this figure, the lower end of the positioning protrusion 56 within the positioning groove 26M abuts against the bottom surface of the positioning groove 26M. The middle portion of the housing 51 is positioned in the height direction (Z direction) because the lower end of the positioning protrusion 56 abuts against the bottom surface of the positioning groove 26M.

[0122] In this embodiment, the positioning protrusion 56 protruding downward from the middle of the housing 51 has the function of positioning the component feeder 11 (more specifically, the middle part of the housing 51 in the front-rear direction) relative to the height direction of the feeder base 23 when it is mounted on the feeder base 23.

[0123] In addition, such as Figure 17 As shown in (b), the positioning protrusion 56 is fitted with a small tolerance dimensional clearance relative to the two walls 26F constituting the positioning groove 26M. The positioning protrusion 56 is able to slide in the Y direction within the positioning groove 26M but is constrained relative to the X direction. Therefore, by engaging the positioning protrusion 56 with the positioning groove 26M, the rear part of the component feeder 11, mounted on the feeder base 23, is positioned laterally (in the X direction) relative to the feeder base 23.

[0124] Here, as previously described, the heads of the plurality of screws 27 that mount the positioning guide 26 to the upper surface of the feeder base 23 do not protrude into the positioning groove 26M, and the alignment protrusion 23T is positioned such that its upper end does not protrude upward from the bottom surface of the positioning groove 26M. Therefore, when the component feeder 11 is loaded or unloaded relative to the feeder base 23, the positioning protrusion 56 of the component feeder 11 will not interfere with the screws 27 or the alignment protrusion 23T in the positioning groove 26M. Therefore, the loading and unloading of the component feeder 11 relative to the feeder base 23 can be performed smoothly, and there is no possibility of damage to the positioning protrusion 56 of the component feeder 11.

[0125] In this embodiment, the positioning guide 26 with the positioning groove 26M is detachable from the feeder base 23 for the feeder trolley 12. During the installation of the component feeder 11, the positioning groove 26M positions the component feeder relative to the feeder base 23 by accommodating the positioning protrusion 56 and supporting the lower surface of the positioning protrusion 56. Therefore, the positioning guide 26 can be manufactured as a different component from the feeder base 23, eliminating the need for machining complex concave and convex shapes on the upper surface of the feeder base 23 as in the past, thus enabling the feeder base 23 to be manufactured at a low cost.

[0126] Furthermore, since the positioning guide 26 can be easily attached to and detached from the feeder base 23, maintenance operations such as cleaning the positioning groove 26M are easy. In addition, even if the wall 26F forming the positioning groove 26M is damaged due to wear, it is not necessary to replace the entire feeder base 23.

[0127] Furthermore, in this embodiment, multiple positioning slots 26M are formed within a single positioning guide, thus enabling unified maintenance of all positioning slots 26M and improving maintenance efficiency. Additionally, in this embodiment, the multiple positioning slots 26M arranged along the sliding direction (X direction) of the component feeder 11 are not all formed on a single positioning guide 26; rather, all of the multiple positioning slots 26M are separately arranged on multiple positioning guides 26. Figure 4 Therefore, the positioning guide 26, which is prone to becoming elongated, can be made into a compact size, making it easy to handle or store.

[0128] During the process of installing the component feeder 11 on the feeder base 23 as described above, the air plug 63, which is a connector component on the feeder side, engages with the air inlet 37, which is a connector component on the trolley side, thus forming an air connector. As a result, air can be supplied from the feeder trolley 12 side (i.e., the component mounting part 1B side) to the component feeder 11 side.

[0129] Here, as described above, the air plug 63 is mounted via the air plug retaining part 83 in a state that allows it to move relative to the lower extension 52 (i.e., relative to the housing 51). Therefore, when the component feeder 11 is mounted on the feeder mounting part 25, even if the housing 51 of the component feeder 11 is slightly tilted laterally, the air plug 63 can smoothly engage with the air inlet 37 on the feeder carriage 12 side. Furthermore, the air plug 63 is pressed from the inside to the outside of the housing 51 by the first tube 92, thus preventing it from falling downwards and maintaining a horizontal posture. Therefore, when the component feeder 11 is mounted on the feeder carriage 12, the air plug 63 can smoothly engage with the air inlet 37 on the feeder carriage 12 side. Moreover, even after engaging with the air inlet 37, the air plug 63 remains pressed from the inside to the outside of the housing 51 by the first tube 92, thus ensuring a secure connection between the air plug 63 and the air inlet 37.

[0130] Furthermore, during the installation of the component feeder 11 onto the feeder base 23 as described above, the feeder-side connector 64 engages with the trolley-side connector 38, and the locking pin 39 on the feeder trolley 12 side engages with the pin engagement hole 65H on the component feeder 11 side. This allows power to be supplied to the component feeder 11 from the component mounting section 1B, and the mounting section control device 17 can control the operation of the component feeder 11. Because the locking pin 39 engages with the pin engagement hole 65H, lateral movement of the rear portion of the component feeder 11 is restricted, and lateral swaying of the rear portion of the housing 51 is prevented when subjected to vibration while mounted on the feeder base 23.

[0131] Furthermore, just before the tip of the housing 51 abuts against the feeder limiter 31 as described above, the hook-shaped member 61 of the component feeder 11 engages with the locking pin 34c of the locking arm 34 of the feeder trolley 12. To describe in detail, when the slider 55 is inserted into the feeder mounting portion 25 and pushed forward (inward) within the housing 51... Figure 18 As shown by arrow A1 in (a), firstly, the beveled portion 61a of the hook-shaped member 61 abuts against the operating pin 34b of the locking arm 34 from the rear. Figure 18 (a)

[0132] When the inclined portion 61a abuts against the operating pin 34b, and is pushed further rearward within the housing 51, the inclined portion 61a of the hook-shaped member 61 pushes the operating pin 34b up. As a result, the locking arm 34 compresses the force-applying spring 34e while swinging about the pivot support shaft 34d. Figure 18As shown by arrow R1 in (b), the push-up state of the operating pin 34b based on the inclined surface 61a is released when the operating pin 34b reaches above the base end recess 61c of the hook member 61. Therefore, the locking arm 34 swings back to its original position due to the restoring force of the force spring 34e. Figure 18 As shown by arrow R2 in (c), the operating pin 34b falls into the base-side recess 61c of the hook-shaped member 61. Simultaneously, the locking pin 34c of the locking arm 34 falls into and engages with the front-side recess 61b of the hook-shaped member 61. Thus, the component feeder 11 is locked to the feeder base 23.

[0133] In this embodiment, the hook-shaped member 61 of the component feeder 11, which is a hook-shaped feeder-side engaging member, engages with the locking pin 34c, which is a trolley-side engaging member provided on the side of the feeder trolley 12, by sliding relative to the feeder base 23 of the feeder trolley 12.

[0134] When the hook-shaped member 61 engages with the locking pin 34c as described above, the hook-shaped member 61 enters the guide passage 36 between two guide plates 35 of the plurality of guide plates 35 provided by the feeder trolley 12, which are located at positions corresponding to the locking pin 34c to which it is engaged. At this time, the two sides of the hook-shaped member 61 are smoothly introduced into the guide passage 36 by the conical surfaces 35M of the two guide plates 35.

[0135] For the hook-shaped member 61 introduced into the guide passage 36, its two sides are guided by a pair of sides (guide surfaces 35G) constituting the guide passage 36. Figure 19 (a)→ Figure 19 (b)), and even after engaging with the locking pin 34c, it remains guided (supported) by a pair of guide surfaces 35G. Here, the distance KK between the pair of guide surfaces 35G is... Figure 5 The hook member 61 is set to be slightly larger than its thickness dimension, and its displacement in the tilting direction toward the housing 51 (i.e., the component feeder 11) is suppressed when both sides are guided (supported) by a pair of guide surfaces 35G. Therefore, even when subjected to the excitation force generated by the component feeder 11's component feeding operation, the lateral sway of the housing 51 can be reduced. Thus, the feeding accuracy of component BH supplied to the component feed port 11K by the component feeder 11 can be improved.

[0136] In this embodiment, the component feeder 11 of the component supply unit 1A includes a hook-shaped member 61 that engages with a locking pin 34c disposed on the side of the feeder carriage 12 by sliding relative to the feeder base 23. The feeder carriage 12 includes a plurality of guide plates 35 arranged in a horizontal direction (X direction) orthogonal to the front-rear direction (Y direction) which is the direction in which the component feeder 11 slides relative to the feeder base 23. Furthermore, the hook-shaped member 61 engages with the locking pin 34c through a guide passage 36 between a pair of guide surfaces 35G that are laterally opposed between two adjacent guide plates 35. The pair of guide surfaces 35G support both sides of the hook-shaped member 61 before and after engagement with the locking pin 34c.

[0137] Therefore, even when the component feeder 11 is made thinner, and it is not possible to sufficiently prevent the lateral tail (in the tilting direction) displacement of the housing 51 by simply fixing the front part of the housing 51 with the slider 55 relative to the feeder base 23, the lateral swaying of the component feeder 11 relative to the feeder base 23 can be suppressed. In addition, since the lateral swaying of the housing 51 can be suppressed, when the component feeder 11 is mounted on the feeder base 23 by sliding, the air plug 63 and the feeder-side connector 64 can smoothly engage with the air inlet 37 and the trolley-side connector 38 on the feeder trolley 12 side, respectively, and the locking pin 39 can smoothly engage with the locking hole 65H.

[0138] When removing the component feeder 11 from the feeder base 23, the operator (OP) slides the component feeder 11 in the opposite direction to when it was installed on the feeder base 23 to pull it out. Specifically, the operator (OP) pulls the operating handle 75 (located on the rear surface of the component feeder 11 to be pulled out of the feeder base 23) backward. Figure 20 Arrow A2 is shown in (a).

[0139] When the operator (OP) pulls the operating handle 75 backward, the sliding member 74 connected to the operating handle 75 slides backward within the sliding space 51S, pulling the upper end of the cable 77 backward. Therefore, the rear end of the rod member 72 connected to the lower end of the cable 77 is pulled up. Figure 13 (a)→ Figure 13 (b) When the rear end of the lever member 72 is pulled up, the front part 72M of the lever member 72 presses down on the operated pin 62P of the locking release member 62. The locking release member 62 swings upward toward the front end with the front pivot support pin 71 as the center. Therefore, the operating pin 34b located in the recess 61c on the base end side of the hook member 61 is pushed upward by the inclined surface 62a of the locking release member 62. Figure 13 (a)→ Figure 13 (b) Figure 21 (a)→ Figure 21 (b) Therefore, the locking pin 34c disengages upward from the front end recess 61b of the hook member 61, and the engagement (locking) between the hook member 61 and the locking pin 34c is released. Figure 21 (a)→ Figure 21 (b)

[0140] When the engagement between the hook-shaped member 61 and the locking pin 34c is released as described above, the component feeder 11 moves rearward on the feeder base 23 by the force applied by the operator OP pulling the operating handle 75 backward. As a result, the slider 55 slides rearward within the feeder mounting portion 25, and the positioning protrusion 56 slides within the positioning groove 26M and disengages from it. Furthermore, the air plug 63 separates from the air inlet 37, the feeder-side connector 64 separates from the trolley-side connector 38, and the engaging pin 39 separates from the engaging hole 65H. Figure 21 (b)→ Figure 21 (c)).

[0141] As described above, slider 55 slides rearward within feeder mounting portion 25, thereby causing the rear slider 55b to disengage rearward from feeder mounting portion 25 first. Figure 22 (a)). At this point, the front slider 55a remains entirely within the feeder mounting portion 25, so although the housing 51 maintains a roughly horizontal posture, when the front slider 55a slides further rearward within the feeder mounting portion 25 and is about to detach from the feeder mounting portion 25, the housing 51 tilts in the rearward downward direction. Figure 22 Arrow B1 shown in (b). Then, the rear end of the front slider 55a abuts against the positioning guide 26 from the front ( Figure 22 (b) and Figure 20 (b) The housing 51 could not be moved further rearward, so the removal of the component feeder 11 from the feeder base 23 (feeder mounting part 25) was interrupted.

[0142] In this manner, a notch 55K is provided in the middle of the slider 55 of the component feeder 11 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 limiter behind the feeder mounting portion 25. Furthermore, when the component feeder 11 moves rearward from the state where the slider 55 is mounted on the feeder mounting portion 25, and the front slider 55a, which is located in the slider 55 in a position more in front of the notch 55K, is about to disengage from the feeder mounting portion 25 and the component feeder 11 tilts in the direction of descending towards the rear of the component feeder 11, the positioning guide 26 abuts against the rear end of the front slider 55a.

[0143] In order to completely remove the component feeder 11 from the feeder mounting part 25 while the removal of the component feeder 11 from the feeder base 23 is interrupted as described above, the operator (OP) holds the handle part 51D provided on the housing 51 with hand HD and lifts the upper rear part of the housing 51. Figure 23 Arrow B2 shown in (a) makes housing 51 in a horizontal position. Figure 23 (a)). Then, when the housing 51 is pulled horizontally backward while holding the handle part 51D ( Figure 23 As shown by arrow A2 in (b), the component feeder 11 is in a state where it is completely pulled out from the feeder base 23.

[0144] Thus, in this embodiment, even when the component feeder 11 is pulled backward by the operating handle 75 while simultaneously releasing the lock on the component feeder 11 relative to the feeder base 23 and pulling the component feeder 11 out of the feeder base 23, the backward movement of the component feeder 11 is interrupted before it is completely pulled out of the feeder base 23. Therefore, the component feeder 11 will not be pulled out of the feeder base 23 all at once when it is being removed from the feeder base 23. Therefore, the component feeder 11 mounted on the feeder trolley 12 can be safely and easily removed with one hand. In addition, since the movement of the component feeder 11 is interrupted, the operator can easily perform operations relative to the component feeder 11.

[0145] As explained above, in the component supply device (component supply unit 1A) and the component mounting device 1 equipped with the component supply device (component supply unit 1A) in this embodiment, the two sides of the hook-shaped member 61 of the component feeder 11 are guided by a pair of guide plates 35 (a pair of guide surfaces 35G) provided by the feeder trolley 12, and the lateral (tilting direction) displacement of the component feeder 11 is suppressed. Therefore, the lateral sway of the component feeder 11 can be reduced, thereby improving the supply accuracy of component BH supplied to the component supply port 11K.

[0146] The embodiments of the present invention have now been described, but the present invention is not limited to the above description and various modifications are possible. For example, the above embodiments have described the case where the component feeder 11 is a feeder with a built-in feeder, but the component feeder 11 is not limited to a feeder with a built-in feeder, and may also be a bulk feeder, etc.
