It can freely swing around. In FIG. 8, the front end of the lever portion 84 abuts a roller 82R provided at the rear end of the clamp release member 82 from above.

8 and 10, the release operation portion 85 is provided at the rear end portion of the body portion 41. As shown in FIG. As also shown in FIGS. 13 and 14, the release operation portion 85 is composed of a slide portion 91, a swing portion 92 and a connecting pin 93. As shown in FIG. 13 and 14 show a state in which the right cover 41R is removed from the body portion 41. FIG.

15(a), (b) and 16, the slide portion 91 has a base portion 91a that spreads along the YZ plane and extends in the Y direction, and a front wall portion 91b that extends rightward from the front end of the base portion 91a. It has The front wall portion 91b is provided with a wire insertion hole 91D passing through the front wall portion 91b in the thickness direction (Y direction), and a block-shaped stopper portion 91S is formed at the right end of the front wall portion 91b. .

One end of the swing portion 92 is a base portion 92K that is connected to the slide portion 91 by a connecting pin 93, and the tip portion of the other end is an operation side end portion 92S that is operated by the operator OP. A base portion 92K of the swing portion 92 is attached to the slide portion 91 by a connecting pin 93, and the swing portion 92 can swing about the connecting pin 93 in the YZ plane with respect to the slide portion 91. As shown in FIG.

In FIG. 16, a base portion 92K of the swing portion 92 is bifurcated. As shown in FIGS. 13, 14 and 15(a) and (b), each of the bifurcated bases 92K has a protrusion 94 (left side) protruding in the opposite direction to the operation side end 92S. A convex portion 94L and a right convex portion 94R) are provided.

14, 17 and 18, the rear portion of the handle portion 51 is provided with a storage portion 101 that opens toward the rear surface 41b. The storage portion 101 is formed by a forward recessed portion of the rear surface 41b of the handle portion 51 and an area surrounded by left and right covers (left cover 41L and right cover 41R) (FIG. 18).

In FIGS. 17 and 18, the handle portion 51 that constitutes the storage portion 101 has a restricting portion 102 that is recessed forward of the rear surface 41b. The restricting portion 102 includes an upper slope portion 102a extending obliquely forward and downward, a lower slope portion 102b extending obliquely rearward and downward from the lower end of the upper slope portion 102a, and a handle extending rearward from the lower end of the lower slope portion 102b. It has a horizontal portion 102c connected to the rear surface of the portion 51 . A first recess 102d is formed at the boundary between the upper slope portion 102a and the lower slope portion 102b, and a second recess 102e is formed at the boundary between the lower slope portion 102b and the horizontal portion 102c.

In FIG. 18, at the rear portion of the handle portion 51, a slide portion passage 103 having an opening in the storage portion 101 and extending in the Y direction is provided. The slide section passage 103 communicates with a window section 104 that opens in the right side surface (including the right cover 41R) of the main body section 41 and extends in the Y direction (FIGS. 13, 14 and 15A, ( b)). As shown in FIGS. 18 and 19(a) and (b), a front wall 103W is formed at the foremost portion of the slide section passage 103, and the front wall 103W extends in the thickness direction (Y direction) is provided.

The slide portion 91 is provided in the slide portion passage 103 and is movable in the Y direction inside the main body portion 41 . When the slide portion 91 moves in the Y direction in the slide portion passage 103, the stopper portion 91S moves in the Y direction in the window portion 104 accordingly. The release operation portion 85 is at a first position (which is a position where the base portion 92K of the swing portion 92 is brought into contact with the restricting portion 102 (specifically, the upper slope portion 102a and the lower slope portion 102b) of the storage portion 101 from behind. 13 and 19(a), and the second position (FIGS. 14 and 19(b)) where the stopper portion 91S is brought into contact with the wall portion 104T, which is the rear edge of the window portion 104, from the front. It is possible to move (slide) between

The swing portion 92 has an upright posture (FIG. 13) in which the operation-side end portion 92S is positioned upward and is brought closer to the main body portion 41 in a state where the release operation portion 85 is located at the first position, and a substantially horizontal posture rearward. It can be moved (swinged) between two positions, namely, a sideways posture (FIG. 14) in which the body portion 41 is extended and separated from the main body portion 41 .

When the swing portion 92 is operated from the lying posture to the standing posture (FIGS. 14→13, FIG. 15(b)→FIG. 15(a), the right convex portion 94R is fitted into the second concave portion 102e of the restricting portion 102. (FIG. 13) Therefore, the swing part 92 is positioned in the standing posture and maintains the standing posture unless operated by the operator OP.

When the swing portion 92 is in the standing posture and stored in the storage portion 101, the claw portion 92T, which is a part of the operation-side end portion 92S, protrudes rearward from the handle portion 51 (FIG. 13). For this reason, the operator OP picks up the claw portion 92T of the swing portion 92 that is in the upright posture and is housed in the storage portion 101, or hooks the claw portion 92T with a finger and pulls out the swing portion 92 rearward. can be easily laid down.

As described above, in the present embodiment, the housing portion 101 for housing the swing portion 92 in the standing posture is provided in the main body portion 41, and the swing portion 92 is provided at the operation side end portion 92S of the swing portion 92. It is configured to have a claw portion 92T that protrudes without being stored in the storage portion 101 even when positioned in the standing posture.

When the swing portion 92 is in the sideways position, the right convex portion 94R of the swing portion 92 fits into the first concave portion 102d of the restricting portion 102 (FIG. 14). Therefore, the swing part 92 is positioned in a sideways attitude and maintains the sideways attitude unless operated by the operator OP.

In this way, the outer shape of each of the portions (specifically, the first concave portion 102d and the second concave portion 102e) of the portion where the convex portion 94 of the base portion 92K of the swing portion 92 and the restricting portion 102 contact each other is such that the swing portion 92 is in the upright posture. The swing portion 92 maintains the upright posture when the swing portion 92 is positioned in the horizontal position, and maintains the sideways posture of the swing portion 92 when the swing portion 92 is positioned in the sideways posture.

A swing portion stopper 91T (FIGS. 15A and 15B) is formed at the rear portion of the slide portion 91. As shown in FIG. A left convex portion 94L formed on the base portion 92K of the swing portion 92 contacts the swing portion stopper 91T from below. Therefore, even when the slide portion 91 moves to the second position, the swing portion 92 does not swing downward beyond the lying position. That is, the swing portion stopper 91T functions as a swing stopper that restricts swinging of the swing portion 92 from the upright posture to the sideways posture.

The swing portion 92 can take a standing posture or a sideways posture with the release operation portion 85 positioned at the first position (FIGS. 13→14, FIG. 15(a)→FIG. 15(b)), By pulling backward the swing portion 92 in the lying posture, the release operation portion 85 can be positioned at the second position (FIGS. 14 to 20). Even when the release operation portion 85 is positioned at the second position, the left convex portion 94L remains in contact with the swing portion stopper 91T. The horizontal posture is maintained even in the pulled-out state (the operation-side end portion 92S does not hang downward).

13, 14 and 15(a), (b), a wire holder 111 is attached to the right surface of the slide portion 91. As shown in FIG. As shown in FIG. 16, the wire holder 111 has a main portion 111a that spreads along the YZ plane and extends in the Y direction, and an extension portion 111b that bends and extends leftward from the rear end of the main portion 111a. have. The main portion 111a is provided with two nuts 111N arranged in the Y direction, and the extension portion 111b is provided with a slit portion 111S extending in the Y direction.

15(a), (b) and 16, the wire holder 111 is attached to the right surface of the slide portion 91 by two bolts 112 arranged on the slide portion 91 in the Y direction. The wire holder 111 is provided with two long holes 91H extending in the Y direction and aligned in the Y direction.

Two bolts 112 pass through the long hole 91H and are screwed to the nut 111N, and the wire holder 111 is fixed to the slide portion 91 by tightening the bolts 112 to the nut 111N. For this reason, the bolt 112 tightened to the nut 111N is once loosened, the wire holder 111 is moved in the Y direction with respect to the slide portion 91, and then the bolt 112 is tightened again, thereby causing the wire holder 111 to slide. The mounting position with respect to the portion 91 can be arbitrarily changed within the range of the length of the long hole 91H in the Y direction.

In FIGS. 7A and 8, the wire 86 extends vertically inside the body portion 41. As shown in FIG. The wire 86 has its upper end attached to the front end of the wire holder 111 and its lower end attached to the lever portion 84 . That is, the wire 86 is a member that connects the release operation portion 85 and the lever portion 84 .

Here, the upper end of the wire 86 is formed in the aforementioned wire hole 103D (FIGS. 18 and 19(a)) provided in the front wall 103W of the slide portion passage 103 and the front wall portion 91b of the slide portion 91. The head 86T is attached to the wire holder 111 by being inserted through the wire insertion hole 91D (FIGS. 16 and 19(a)) and engaging the head 86T with the slit 111S. A lower end of the wire 86 is attached to the rear end of the lever portion 84 .

8 and 10, of the upper end portion of the wire 86, the portion immediately after protruding forward from the slide portion 91 is guided by an arc-shaped guide surface 41M (FIG. 17) formed in the body portion 41. Supported. Therefore, the wire 86 extends forward from the upper end portion to the guide surface 41M, is bent downward at the guide surface 41M, and extends downward (toward the lever portion 84).

As described above, the lever portion 84 abuts from above the roller 82R at the rear end of the clamp release member 82 biased in the front end lowering direction by the return spring 83, and the return spring 83 moves through the clamp release member 82 to the front end. It receives a biasing force in the upward direction. The length of the wire 86 is adjusted so that the wire 86 is fully stretched (tensioned) when the release operation portion 85 is positioned at the first position.

That is, in the present embodiment, the clamp release mechanism 80 includes a return spring 83 as an elastic body that biases the release operation portion 85 in the direction to pull it inside the body portion 41 , and the body portion 41 contacts the swing portion 92 . The releasing operation portion 85 biased by the return spring 83 is provided with a restricting portion 102 that restricts the movement toward the inside of the main body portion 41 by coming into contact therewith.

As shown in FIGS. 8 and 22, when the release operation portion 85 is located at the first position, the clamp release member 82 assumes a substantially horizontal posture (see also FIG. 12(a)). Further, the clamp release member 82 is positioned at a position (referred to as a "standby position") where the clamp release claw 82T is substantially the same as or lower than the bottom surface of the relief portion 81H of the clamped member 81. As shown in FIG.

After the operator OP swings the swing portion 92, which is in the standing posture at the first position, to a sideways posture (arrow P1 shown in FIG. 22), the release operation portion 85 is placed in the sideways posture. is pulled rearward (arrow P2 shown in FIG. 23), the rear end of the lever portion 84 is pulled upward through the wire 86 . As a result, the lever portion 84 pivots about the lever portion support pin 84P in the front end lowering direction (arrow R1 shown in FIG. 23), and the rear end portion of the clamp release member 82 is pushed down via the roller 82R.

When the rear end side of the clamp releasing member 82 is pushed down, the clamp releasing member 82 swings about the pin 82P against the biasing force of the return spring 83 (arrow R2 shown in FIG. 23). Then, it stops at a position where the upper surface of the clamp release claw 82T is higher than the cam surface 81C (referred to as a "clamp release position") (see also FIG. 12(b)). That is, when the operator OP moves (pulls backward) the release operation portion 85 from the first position to the second position, the clamp release member 82 moves (swings) from the standby position to the clamp release position.

By thus moving the release operation portion 85 from the first position to the second position, the operation force of the release operation portion 85 is applied to the wire 86 when the clamp release member 82 moves from the standby position to the clamp release position. and is transmitted to the clamp release member 82 through the lever portion 84 . At this time, the wire 86 and the lever portion 84 constitute a transmission portion DB that transmits the displacement of the release operation portion 85 to the clamp release member 82 (FIGS. 22 and 23).

When attaching the parts feeder 13 having such a configuration to the feeder base 22, the operator OP inserts the front end of the slot insertion portion 52 into the slot while the release operation portion 85 is positioned at the first position in the standing posture. It is inserted into the groove 23S. Then, the body portion 41 is slid along the slot groove 23S in the mounting direction (arrow At shown in FIG. 24A), and the body portion 41 is moved toward the feeder base until the front surface 41a of the body portion 41 contacts the feeder stopper 24. Push it into the back side of 22.

When the body portion 41 is pushed into the feeder base 22 in this way, in the process, the recessed portion 81K of the clamped member 81 on the parts feeder 13 side is pushed into the stator 34 of the clamping mechanism 31 on the feeder base 22 side. engage with. Thereby, the clamped member 81 is clamped by the clamping mechanism 31, and the parts feeder 13 is fixed (clamped) to the feeder base 22 (FIG. 24(b)).

In addition, in the process of pushing the body portion 41 into the depth side of the feeder base 22, the upper pin 54 and the lower pin 55 of the parts feeder 13 are pushed into the upper pin insertion hole 24A and the lower pin insertion hole 24B of the feeder stopper 24, respectively. , and the socket 57 of the parts feeder 13 is connected to the plug 26 provided on the feeder base 22 side. By connecting the socket 57 to the plug 26, the control section 44 on the parts feeder 13 side and the control device 17 on the component mounting apparatus 1 side are electrically connected.

Here, the clamping operation of the clamped member 81 by the clamping mechanism 31 will be described in detail with reference to FIGS. When the slot insertion portion 52 of the parts feeder 13 is inserted into the slot groove 23S of the feeder base 22 and the body portion 41 is pushed in the mounting direction (arrow At shown in FIG. 25(a)), first, the clamped member 81 The cam surface 81C contacts the operated portion 33 of the clamp mechanism 31 (FIG. 25(a)→FIG. 25(b)). Here, since the highest point 81G of the front end portion 81F of the clamped member 81 is at a position lower than the operated portion 33, it does not contact the operated portion 33, and the cam surface 81C contacts the operated portion 33. become.

When the parts feeder 13 is further pushed in the mounting direction from the state in which the cam surface 81C is in contact with the operated portion 33 (an arrow At shown in FIG. 26A), the cam surface 81C moves toward the operated portion 33 due to its slope shape. Move forward while pushing up. As a result, the arm 32 swings around the support shaft 22J against the biasing force of the biasing spring 36 in the direction of raising the rear end (arrow M shown in FIG. 26(a)).

When the arm 32 is pushed up by the cam surface 81C and swings in the rear end raising direction, the stator 34 moves upward. When the highest point of the rear end of the cam surface 81C (the highest point 81CG of the rear end of the cam surface) reaches directly below the operated portion 33, the highest point 81G of the front end portion 81F is directly below the stator 34 or the center of the stator 34. in the mounting direction (FIG. 26(a)). During this time, the cam surface 81C functions to lift the stator 34 against the strong biasing spring 36 required to fix the parts feeder 13 to the feeder base 22 with sufficient clamping force.

When the parts feeder 13 is further pushed in the mounting direction and the front surface 41a of the main body 41 abuts against the feeder stopper 24, the relief portion 81H of the clamped member 81 reaches directly below the operated portion 33, and the recessed portion 81K is also fixed. It reaches just below the child 34 (FIG. 26(b)). At this time, the operated portion 33, which has lost support from the cam surface 81C, falls into the escape portion 81H, so that the arm 32 swings about the support shaft 22J in the rear end lowering direction (the arrow shown in FIG. 26(b)). N). Then, the stator 34 descends as the arm 32 swings, is pressed against the recessed portion 81K that has moved directly below, and engages with the clamped member 81, thereby fixing the parts feeder 13 to the feeder base 22 ( clamped (FIGS. 26(c) and 24(b)).

As described above, in the present embodiment, the clamping mechanism 31 includes the stator 34 and the operated portion 33. The stator 34 and the operated portion 33 are arranged horizontally with respect to the mounting direction of the parts feeder 13. It is configured to be attached to an arm 32 that swings about an intersecting axis (pin 82P). The arm 32 extends in a direction (detachment direction, rearward) opposite to the mounting direction (forward) of the parts feeder 13, and holds the stator 34 at a position spaced rearward from the pin 82P. It has an operated part 33 at a position separated from the body. The clamped member 81 pushes up the operated portion 33 with the cam surface 81C. The cam surface 81C is an inclined surface that rises in the opposite direction (removal direction) to the mounting direction of the parts feeder 13, and when the clamped member 81 moves in the mounting direction of the parts feeder 13, the operated portion 33 moves upward. Displace. That is, the stator 34 is not directly pushed up by the cam surface 81C, but is indirectly pushed up by operating the operated portion 33. As shown in FIG.

As described above, since the mounting position of the operated portion 33 is located at a greater distance from the support shaft 22J than the mounting position of the stator 34, the clamped member 81 can be pushed up more than the case where the stator 34 is directly pushed up. The stator 34 can be pushed up to a height that does not interfere with the highest point 81G of the front end portion 81F of the clamped member 81 with a small force. In addition, the reaction force from the clamp mechanism 31 when pushing the parts feeder 13 into the feeder base 22 can be reduced in combination with the boosting action of the cam surface 81C. In other words, the pushing force when pushing the parts feeder 13 into the feeder base 22 can be reduced.

Next, the clamp release operation by the clamp release mechanism 80 will be described with reference to FIGS. 27(a), (b), FIGS. 28(a), (b) and FIGS. When removing the parts feeder 13 attached to the feeder base 22, the operator OP first swings the swing portion 92 of the release operation portion 85 from the standing posture to the lying posture (shown in FIG. 22). Arrow P1). Then, by pulling the swing portion 92 in the sideways posture backward (arrow P2 shown in FIG. 27(a)), the entire parts feeder 13 is moved in the direction (rearward) away from the feeder base 22 ( FIG. 27(a)→FIG. 27(b)).

When the swing portion 92 is pulled rearward by the operator OP, the slide portion 91 moves rearward, and the lever portion 84 swings in the direction of lowering the front end through the wire 86 (Fig. 22 → Fig. 23, Fig. 28(a) → FIG. 28(b)). As a result, the operated portion 33 in the relief portion 81H of the clamped member 81 is pushed up by the clamp release pawl 82T, and the height is the same as or higher than the cam surface rear end highest point 81CG adjacent to the relief portion 81H. (Fig. 28(b)). When the operated portion 33 is lifted to a height equal to or higher than the rear end highest point 81CG of the cam surface, the stator 34 is separated from the recessed portion 81K (Fig. 29(a)). The clamped state by the stator 34 is released.

As described above, in the parts feeder 13 of the present embodiment, the release operation portion 85 and the lever portion 84 are connected by the wire 86, and when the release operation portion 85 is pulled rearward of the main body portion 41, the lever portion 84 is disengaged. swings to separate the stator 34 from the clamped member 81 (more specifically, the recessed portion 81K). In such a configuration, the direction of the force can be easily changed by using the wire 86, so that the mechanism for operating the lever portion 84 by the release operation portion 85 can be made lightweight and compact.

Note that the wire 86 may elongate due to aging. If the elongation of the wire 86 becomes large, even if the release operation part 85 is moved to the second position, the amount of pushing up the operated part 33 by the clamp release claw 82T becomes insufficient. In this case, when the parts feeder 13 is slid in the detachment direction (arrow Re shown in FIG. 27(a)) (arrow P2 shown in FIG. 27(a)), the clamped member 81 is attached to the operated portion 33. The highest point 81CG of the rear end of the cam surface collides with the stator 34, or the highest point 81G of the clamped member 81 collides with the stator 34, not only hindering the removal work of the parts feeder 13, but also removing it from the feeder base 22 in the worst case. I can't do it. For this reason, in the present embodiment, the sliding portion 91 is provided with a wire adjusting function for correcting the influence of the elongation of the wire 86 .

As described above, the position of the wire holder 111 in the Y direction with respect to the slide portion 91 can be changed within the range of the length of the slot 91H provided in the slide portion 91 in the Y direction. By changing the position of the wire holder 111, it is possible to change the position of the swinging direction of the clamp release member 82 interlocking with the lever portion 84, and finally adjust the position (height) of the clamp release claw 82T. can. Therefore, by changing the Y-direction position of the wire holder 111 with respect to the slide portion 91, the distance LG between the front wall portion 91b of the slide portion 91 and the head portion 86T of the wire 86 (Fig. 21(a), ( b)) can be changed, and the position of the clamp release pawl 82T is also adjusted in proportion to the amount of change in the distance LG.

As described above, in the present embodiment, the long hole 91H, the nut 111N and the bolt 112 support the wire with respect to the slide portion 91 in a state in which the position of the wire holder 111 in the slide direction (Y direction) of the slide portion 91 can be adjusted. Attaching the holder 111 serves as a wire adjusting portion WC for adjusting the position of the clamp releasing member 82 (FIGS. 21(a) and 21(b)).

The operator OP continues to pull the release operation portion 85 rearward of the main body portion 41 by pulling the release operation portion 85 rearward, even after the clamping of the clamped member 81 by the stator 34 is released (Fig. P1) shown in 29(b). As a result, the slot insertion portion 52 moves backward and comes out of the feeder base 22 , so that the parts feeder 13 can be removed from the feeder base 22 . During this time, the depressed portion 81K of the clamped member 81 moves away from the stator 34 (FIG. 26(c)→FIG. 29(a)), and the operated portion 33 moves along the cam surface 81C of the clamped member 81. Afterwards (FIG. 28(b)→FIG. 29(a)), it is separated from the cam surface 81C (FIG. 29(b)).

As described above, in the parts feeder 13 according to the present embodiment, after the releasing operation portion 85 is pulled rearward of the body portion 41 and the lever portion 84 operates to release the clamping of the stator 34 by the clamped member 81, Further, when the release operation portion 85 is pulled rearward from the main body portion 41, the slot insertion portion 52 is pulled out of the slot groove 23S by the pulling force. Therefore, the operator OP can smoothly perform both the work of releasing and removing the parts feeder 13 by pulling the release operation portion 85 in the detachment direction (backward).

As described above, in the parts feeder 13 according to the present embodiment, the release operation portion 85 operated by the operator OP in order to make the body portion 41 removable from the feeder base 22 slides with respect to the body portion 41 . and a base portion 92K is connected to the slide portion 91 so as to be able to swing. When the operator OP pulls the release operation part 85 in the horizontal direction with the release operation part 85 lying down, the fixation of the main body part 41 to the feeder base 22 is released and the feeder is released. The parts feeder 13 can be detached from the base 22. - 特許庁

The clamp release operation of the parts feeder 13 with respect to the feeder base 22 is extremely simple, and the direction of the clamp release operation matches the removal direction (sliding direction) of the parts feeder 13 from the feeder base 22. Even when the operation is performed by a robot, the operation is simple, and it is possible to prevent an increase in cost due to the use of an expensive robot that requires complicated motions. Moreover, if the swing part 92 is kept in the upright position and brought close to the main body part 41 except when the parts feeder 13 is removed from the feeder base 22, the swing part 92 does not interfere with the operator OP, so workability is good.

The work instruction section SSB (FIG. 1) of the component mounting line described above grasps the type of each parts feeder 13 mounted on the feeder base 22 of the component mounting apparatus 1, and determines the type of board KB to be produced. When it becomes necessary to replace the parts feeder 13 at the time of setup change, the parts feeder 13 to be replaced (to be removed from the feeder base 22) is notified to the component mounting apparatus 1. - 特許庁Then, the control device 17 of the component mounting device 1 that has received the notification from the work instructing section SSB lights or blinks the lamp 63 of the parts feeder 13 to be replaced. When the operator OP finds the parts feeder 13 with the lamp 63 lit or blinking, the operator OP finds the parts feeder 13 to be removed from among the plurality of parts feeders 13 on the feeder base 22 by relying on the lamp 63, and removes the parts feeder 13. The parts feeder 13 is removed from the feeder base 22 by pulling the swing part 92 provided on the handle part 51 of the parts feeder 13 backward.

The operator OP needs to find the parts feeder 13 with the lamp 63 lit or blinking from among the plurality of parts feeders 13 arranged on the feeder base 22 . Therefore, the layout of the lamps 63 on the operation panel 60 is preferably such that the lighting or blinking state of the lamps 63 can be easily found.

In this embodiment, the operation panel 60 is provided in a region including the corner 51E between the rear surface 41b and the upper surface 41c of the handle portion 51, and the operation panel 60 is provided only on the upper surface 41c of the conventional handle portion 51. The operation switch 61 and the lamp 63 can be arranged with a higher degree of freedom than in the case where they are provided. Therefore, the operation switch 61 and the lamp 63 can be arranged apart from each other, and the size of each can be increased, so that the operability and visibility of the operation panel 60 can be improved. Particularly, in this embodiment, the operation switch 61 is arranged on the upper surface 41c of the handle portion 51 so that the operator OP can easily operate it, while the lamp 63 is arranged on the rear surface 41b of the handle portion 51. Therefore, it is difficult for the operator OP to overlook the lit or blinking lamp 63 (easy to find).

In addition, since the ramp 63 is arranged on the rear surface 41b of the handle portion 51, when the operator OP removes the parts feeder 13 from the feeder base 22, the operator OP can remove the parts feeder 13 to be removed from another parts feeder adjacently arranged. It is easy to distinguish from 13. In other words, since the ramp 63 is arranged in the immediate vicinity of the release operation portion 85 (specifically, the swing portion 92), human error such as erroneously removing the parts feeder 13 adjacent to the parts feeder 13 indicated by the ramp 63 is avoided. can be prevented from occurring.

In this embodiment, the operation panel 60 has a main panel 60A having an operation switch 61, a sub-panel 60B having a lamp 63, and a connecting portion 60C connecting the main panel 60A and the sub-panel 60B. . Although the operation panel 60 having such a structure is one member, the operation switches 61 and the lamps 63 can be arranged on both the upper surface 41c and the rear surface 41b of the handle portion 51, so that the number of parts can be reduced. Therefore, compared to the case where these panels are manufactured separately, the work for attaching the operation panel 60 to the handle portion 51 and the storage and management of the operation panel 60 before being attached to the handle portion 51 are easier.

As described above, in the parts feeder 13 according to the present embodiment, when the releasing operation portion 85 is laid down and pulled horizontally, the fixation (clamping) of the main body portion 41 to the feeder base 22 is released. The parts feeder 13 is detached from the feeder base 22. - 特許庁Therefore, the work of removing the parts feeder 13 from the feeder base 22 can be performed with an extremely simple operation. Further, since the operation direction of the release operation portion 85 (pulling direction of the swing portion 92) and the removal direction (sliding direction) of the parts feeder 13 from the feeder base 22 are the same when the clamp is released, these operations can be performed by the robot. Even in the case of making the robot perform simple operations, it is possible to prevent an increase in cost due to the use of expensive robots that require complicated operations. Moreover, if the swing part 92 is kept in the upright position and brought close to the main body part 41 except when the parts feeder 13 is removed from the feeder base 22, the swing part 92 does not interfere with the operator OP, resulting in good workability.

Although the embodiments of the present invention have been described so far, the present invention is not limited to those described above, and various modifications and the like are possible. For example, in the above-described embodiment, the transmission portion DB for transmitting the displacement of the release operation portion 85 to the clamp release member 82 was composed of the wire 86 and the lever portion 84, but it may be composed of other structures such as a link. good too. Also, in the above embodiment, the parts feeder 13 is a tape feeder, but it is not limited to a tape feeder, and may be a bulk feeder, a stick feeder, or the like.
