Description

  The present invention relates to a component supply unit that supplies electrical components (including electronic components) from taping electrical components, and more particularly to supply of a plurality of types of taping electrical components.

  The taping electrical component is formed by holding a plurality of electrical components on a carrier tape at an equal pitch. Therefore, a component supply unit for supplying electrical components from taping electrical components conventionally has (A) a main body having a tape guide portion for guiding the taping electrical components, and (B) taping electrical components guided by the tape guide portions. A feeding device that feeds in the longitudinal direction and sequentially positions a plurality of electrical components one by one at the component supply position.

  The taping electrical components supplied in such a component supply unit include a plurality of types of taping electrical components having different types, dimensions (width, thickness, etc.) and holding pitches of electrical components. For example, the mold includes an embossed carrier type taping electrical component, a punch carrier type taping electrical component, and a lead wire terminal taping electrical component. An embossed carrier-type taping electrical component includes a pair of supported portions extending in the longitudinal direction on both sides in the width direction, and a plurality of embosses protruding downward from both supported portions between the two supported portions. One of the electrical components is accommodated in each of these, and the embossed opening is covered with a top cover tape affixed to the carrier tape. The punch carrier-type taping electrical component has one electrical component accommodated in each of a plurality of electrical component accommodating recesses formed by attaching a bottom cover tape to a base tape provided with a plurality of through holes penetrating in the thickness direction. The opening of the electrical component housing recess is covered with a top cover tape affixed to the base tape. The base tape provided with the through holes is made of paper or synthetic resin, and the base tape and the bottom cover tape are collectively referred to as a carrier tape. In the lead wire terminal taping type electric component, the lead wire of the electric component is attached and held on a carrier tape made of an adhesive tape, or is attached and held on a carrier tape including an adhesive tape and a mount. Each type has a plurality of types having different widths, thicknesses, holding pitches of electric parts, and the like.

Conventionally, various measures have been taken to cope with the difference in the types of taping electrical components. For example, in the component supply unit described in Japanese Patent Application Laid-Open No. 8-23190, a pair of supported parts is used by using a width changing block to supply electrical components from a plurality of types of embossed carrier taping electrical components having different widths. The support interval of the part is changed. A pair of support rails are fixed to the main body of the component supply unit, and a pair of supported portions of the carrier tape are supported and guided with the upper surface of each support rail as a support surface. The width changing block is provided in close contact with each other, and the distance between the width changing block and the other support rail is changed to a size capable of supporting the pair of supported portions. If a plurality of types of width changing blocks having different widths are prepared, it is possible to cope with changes in three or more stages of the width of the taping electrical component.
Also, in this publication, one of a pair of support rails is a fixed support rail provided with a fixed position, and the other is a movable support rail that can approach and separate from the fixed support rail. It is also described that the distance between the fixed support rails is adjusted by movement to change the support interval of the taping electrical components.
According to the component supply unit described in this publication, it is possible to cope with the difference in the width of the embossed carrier type taping electrical component, but it cannot cope with the difference in the type of the taping electrical component. If they are different, a component supply unit corresponding to each mold was used. For example, in the case of a component supply unit that supplies an electrical component from an embossed carrier-type taping electrical component, a pair of support rails that support a pair of supported portions and a pair of support rails are provided between the pair of support rails so as to pass the emboss. In the case of a component supply unit that supplies an electrical component from a punch carrier type taping electrical component, it has a support surface that supports and guides the bottom cover tape from the bottom surface. is there.
In addition, in order to prevent the taping electrical component from floating from the main body, a cover is provided on the main body, and the cover also performs positioning of the taping electric component in the width direction. ing.

However, in the component supply unit described in the above publication, the main body may have a width capable of supporting the taping electrical component having the maximum width among a plurality of types of taping electrical components scheduled to be supplied. is necessary. Thus, for example, when mounting a plurality of component supply units on a table with component supply units aligned along a straight line, the mounting pitch of the component supply units is determined by the maximum width of the taping electrical component, and the taping Even in the case of supplying electrical components from the components, there is a problem that the mounting pitch is large and the number of mounting of the component supply units is reduced, leading to a decrease in supply efficiency.
When one of the pair of support rails is a movable support rail, it is inevitable that the structure of the component supply unit is complicated.
Furthermore, if a component supply unit corresponding to each type is made to cope with the difference in the types of taping electrical components, the types of component supply units increase, and the cost reduction effect due to mass production cannot be enjoyed.
Further, when the cover prevents the taping electrical component from being lifted from the main body, there is a problem that it cannot cope with the difference in the holding pitch of the electrical component. It is desirable that the cover does not interfere with the removal of the electric component from the carrier tape and covers the electric component to be taken out as much as possible with the electric component adjacent to the upstream side in the feeding direction of the taping electric component. If the cover is provided at a position that allows the electrical component to be taken out, regardless of whether the dimension or holding pitch of the electrical component in the feed direction is large or small, if the electrical component is small, the upstream electrical component is covered by the cover. An unforeseen situation occurs.
In the case where the cover prevents the taping electrical component from being lifted from the main body, the thickness of the taping electrical component (the thickness of the taping electrical component from the support surface provided on the main body to support and guide the taping electrical component) There was a problem that could not cope with the difference in height. If the thickness of the electrical component to be held changes and the thickness of the taping electrical component changes, while allowing the feeding of the taping electrical component supported by the cover corresponding to the thickness of the taping electrical component, that is, the support surface of the main body, It is necessary to provide a cover that can contact the taping electrical component and prevent the taping electrical component from being lifted from the main body, and it is inevitable that the number of types of the cover increases.

(12) a main body having a support surface for supporting and guiding a taping electric component formed by holding a plurality of electric components on a carrier tape at an equal pitch;
In a component supply unit including a feeding device that feeds taping electrical components guided by the support surface in a longitudinal direction and positions the plurality of electrical components one by one at a component supply position.
A cover for preventing the taping electrical component from floating from the support surface is attached to the main body, and the cover includes a plurality of taping electrical components having a plurality of different heights from the support surface. The component supply unit which has a contact part which contacts an upper surface in both the upstream and downstream of the engaging part with the said feeder of the taping electrical components, and presses those both parts to a support surface.
The portion forming the support surface of the main body constitutes the tape guide portion. The main body may or may not be divided into a main body member and a tape guide member. If separated, the tape guide member can be replaced to cope with the difference in the type and width of the taping electrical component as described in the paragraphs (4) and (6), and the cover has the contact portion. Thus, it is possible to cope with the difference in height from the support surface of the upper surface of the taping electrical component. When divided, the cover may be attached to the main body member or the tape guide member.
The difference in height from the support surface of the upper surfaces of a plurality of types of taping electrical components occurs, for example, when the taping electrical components have different molds or have different thicknesses even if the molds are the same. In the embossed carrier type taping electrical component, the thickness of the pair of supported parts provided on the carrier tape is the height from the support surface. In the punch carrier type taping electrical component, the thickness of the carrier tape and the top cover tape This is because the sum of the thickness and the thickness is the height from the support surface. Further, even if the mold is the same, the height from the support surface differs depending on the thickness of the supported portion in the embossed carrier type taping electrical component, and in the punch carrier type taping electrical component, the height of the electrical component is The thickness of the base tape varies depending on the difference, and the height from the support surface varies.
Therefore, even when the main body is divided into the main body member and the tape guide member, and the embossed carrier type taping electrical component and the punch carrier type taping electrical component are respectively guided by the dedicated tape guide member, the embossed carrier type taping electrical component is used. If the height of the support surface provided on the tape guide member for parts and the height of the support surface provided on the tape guide member for punch carrier type taping electrical parts are the same, the embossed carrier type taping electrical parts and the punch carrier type The height from the support surface of each upper surface with the taping electrical component is different. Further, even if the taping electrical component mold is the same, the height of the upper surface of the taping electrical component from the support surface is different if the thickness is different.
When the main body is not divided into the main body member and the tape guide member, and the embossed carrier type taping electrical component and the punch carrier type taping electrical component are supported by the same support surface, or the main body is divided into the main body member and the tape guide member. Even if separated, the support surface of the tape guide member for punch carrier type taping electrical parts supports and guides the bottom surface of the emboss of the emboss carrier type taping electrical parts, and supports the bottom cover tape of the punch carrier type taping electrical parts.

Further, the support surface of the tape guide member for the embossed carrier type taping electrical component supports and guides the supported portion of the embossed carrier type taping electrical component, and supports and guides the bottom cover tape of the punch carrier type taping electrical component. Even in this case, the height of the upper surface of each taping electrical component from the support surface varies depending on the difference in thickness between both taping electrical components. Even if the taping electric component mold is the same, the height of the upper surface of the taping electric component from the support surface is different if the thickness is different.
The cover of the component supply unit according to this aspect has an upper surface at two locations on the upstream side and the downstream side of the engaging portion with the feeding device of the taping electrical component, even if the height of the taping electrical component from the support surface is different. Since the two parts are pressed against the support surface, the lifting of the engaging portion with the feeding device for the taping electrical component can be prevented well. According to this aspect, the countermeasure against the change in the height of the upper surface of the taping electrical component from the support surface is improved, and the number of types of the cover and the component supply unit can be reduced, and the cost can be reduced. .
In addition, when the main body is divided into the main body member and the tape guide member, the cover may be attached to the main body member, or may be attached to the tape guide member. In the former case, the cover may prevent the lifting of a plurality of types of taping electrical components having different types, or the cover may prevent the lifting of a plurality of types of taping electrical components having the same thickness but different thicknesses. In any case, it contacts the two parts of the taping electrical component to prevent lifting. Even when the cover is attached to the tape guide member, if the tape guide member is dedicated to a specific type of taping electrical component, it can be used for multiple types of taping electrical components with the same mold and different thickness. If the tape guide member is shared by multiple types of taping electrical components with different molds to prevent lifting, multiple types of taping electrical components with different types or multiple types of taping with the same type and different thickness Prevents electrical components from floating.
(13) The cover is attached to the main body so as to be rotatable about a rotation axis parallel to the width direction of the taping electrical component, and upstream of the engaging portion of the taping electrical component with the feeding device. One of the contact parts which contact the upper surface of a taping electric component in the side and downstream is comprised by the elastic member which can be elastically deformed to an up-down direction, The component supply unit as described in the (12) term.
The cover can be attached to the main body so as to be movable in the vertical direction. In this case, even if the thickness of the taping electrical component changes, the cover can be easily connected to the upstream side of the engaging portion with the feeder. It can be brought into contact with the upper surface of the taping electrical component both on the downstream side. On the other hand, the cover can be easily attached if it can be rotated about a rotation axis parallel to the width direction of the taping electrical component. However, if the thickness of the taping electrical component is different, the inclination of the cover with respect to the main body changes. For this reason, it is difficult to make contact on both the upstream side and the downstream side of the engaging portion with the feeding device. According to this aspect, this difficulty can be eliminated.

If the cover 210 is rotated with the small diameter portion 236 of the engaging pin 226 positioned in the engaging hole 232 against the urging force, the cover 210 is engaged with the engaging pin 226. And can be rotated around the shaft 218. Note that the movement of the wide portion 222 relative to the sixth member 52 is permitted by a notch 238 (see FIG. 24) provided in the sixth member 52. Further, the movement limit of the pair of engagement pins 226 due to the urging of the spring member 228 is defined by a movement limit defining member (not shown), and the engagement pin 226 is prevented from being pulled out from the through hole 224. The movement limit defining member is also an extraction preventing member.

  As shown in FIGS. 19 and 21, the first member 42 is provided with notches 240 at two locations separated in the longitudinal direction, and the sixth member 52 is placed on the first member 42. In addition, the mounting leg 206 is fitted into the notch 240, the positioning surface 208 is brought into contact with the upper surface 242 of the first member 42, and the positioning surface 209 is brought into contact with the notch forming surface 244 of the first member 42. It has been. Accordingly, the sixth member 52 is accurately positioned with respect to the first member 42 in the width direction and the vertical direction (a direction perpendicular to the width direction and the longitudinal direction), and the first member 42 is first fixed by a bolt 246 which is a kind of fixing means. A sixth member 52 is attached to the first member 42 and is detachably fixed to the member 42. The upper surface 242 and the notch forming surface 244 are positioning surfaces for positioning the sixth member 52, and constitute positioning means together with the positioning surfaces 208 and 209. The positioning surface 209 is also a reference surface that determines the position of the sixth member 52 in the width direction with respect to the first member 42.

  Further, the downstream mounting leg 206 is brought into contact with the end surface 247 of the downstream notch 240 in the electrical component feeding direction, and the sixth member 52 is positioned with respect to the first member 42 in the electrical component feeding direction. Yes. The upstream notch 240 in the electrical component feed direction allows the fitting of the upstream mounting leg 206 in the electrical component feed direction when the sixth member 52 is thus positioned with respect to the first member 42. Have dimensions to A portion where the positioning surfaces 208 and 209 of the sixth member 52 are provided is an attachment portion to the first member 42 which is a main body member. Further, the portion of the sixth member 52 including the support rail 198 provided with the support surface 202 that supports the supported portion 68 provided with the feed hole 74 of the carrier tape 64 corresponds to the taping electric component feeding device 90. Parts (corresponding to sprockets which will be described later, which are constituent elements of the taping electrical component feeding device 90), and these mounting portions and portions corresponding to the taping electrical component feeding device 90 are on one side in the width direction of the sixth member 52. Is provided.

  In a state where the sixth member 52 is fixed to the first member 42, a through hole 248 (see FIG. 24) formed through the sixth member 52 in the thickness direction and a long hole 250 ( As shown in FIG. 19, the slide 214 is prevented from being lifted by the head 254 of the screw 252 and the slide 214 is It is fixed to the first member 42. The screw 252 is also a lift prevention means.

  Prior to the slide 214 being fixed to the first member 42, the position of the cover 210 in the direction parallel to the electric component feeding direction is adjusted. 20 and 24, a plurality of conical holes 256 are provided at equal intervals in the longitudinal direction of the sixth member 52, and one of the conical holes 256 is provided at the rear portion of the slide 214. In addition, when the ball 260 of the ball plunger 258 provided on the first member 42 is fitted, the slide 214 is positioned, and the cover 210 is positioned in a direction parallel to the electric component feeding direction. A plurality of center holes are formed in the slide 214, and the opening of each center hole forms a conical hole 256. As shown in FIG. 19, the ball plunger 258 is urged in a direction in which the ball 260 is fitted into a casing 262 provided with an external thread on the outer peripheral surface and protrudes from the casing 262 by a spring member 264. The casing 262 is screwed to the first member 42. The ball 260 is retracted into the casing 262 against the urging force of the spring member 264 and moved away from the conical hole 256, so that the slide 214 is allowed to move, and the ball 260 is inserted into the conical hole 256, whereby the slide 214 That is, the cover 210 is positioned.

  The position of the cover 210 is changed in a plurality of stages by the number of the conical holes 256 with respect to the unit main body 40 including the first member 42 and the sixth member 52. For example, the position shown in FIG. The position is changed to the position shown in 24 (b). The position of the cover 210 is changed stepwise according to the dimension of the electric component 60 in the direction parallel to the electric component feeding direction, that is, the holding pitch of the electric component of the taping electric component, and the electric component moved to the component supply position. The electrical component that is allowed to be taken out from the emboss 70 and moved to the component supply position is a position that covers the electrical component adjacent to the upstream side in the electrical component feed direction.

  The cover 210 is attached to the first member 42 together with the sixth member 52 while being attached to the sixth member 52. Then, after fixing the sixth member 52 to the first member 42, the cover 210 is moved to a position corresponding to the holding pitch of the electric component in the electric component feeding direction, and the ball 260 of the ball plunger 258 is fitted into the conical hole 256. In this state, the screw 252 is screwed into the first member 42 through the elongated hole 250, and the slide 214, that is, the cover 210 is fixed to the first member 42 in a direction parallel to the electric component feeding direction. . Therefore, even if vibration is applied to the supply unit 32, the cover 210 is not likely to be displaced. Even in this state, the cover 210 can be disengaged from the slide 214 and rotated around the shaft 218.

  When setting the taping electrical component 62 to the sixth member 52, the cover 210 is removed from the engagement pin 226, rotated around the shaft 218, and retracted from the sixth member 52. After the embossing 70 of the taping electrical component 62 is fitted in the groove 190, the pair of supported portions 68 are placed on the support surfaces 202 and 204, and the feed hole 74 is engaged with a sprocket protrusion described later. The cover 210 is rotated and put on the taping electrical component 62. At this time, the engaging pin 226 is retracted into the through hole 224 against the urging force of the spring member 228, and the small diameter portion 236 is positioned at a position corresponding to the notch 234. Then, by rotating the cover 210 and releasing the force applied to the engagement pin 226 in a state where the small diameter portion 236 is inserted into the engagement hole 232 through the notch 234, the spring member 228 is biased. The engaging portion 230 is fitted into the engaging hole 232, and the cover 210 is locked to the slide 214. In this state, the cover 210 cannot rotate and does not move when the top cover tape 66 is peeled from the carrier tape 64. The positional deviation in the width direction of the taping electrical component 62 is prevented by fitting the emboss 70 into the groove 190 or by the pair of U-shaped side walls of the cover 210 preventing the positional deviation of the pair of supported portions 68 of the carrier tape 64. This is prevented.

  Once the sixth member 52 and the cover 210 are fixed to the first member 42, the type of taping electrical component changes, and when changing the position of the cover 210, the operator loosens the screw 252 and covers the cover. After releasing the fixing of 210 to the first member 42, holding the cover 210, the slide 214 is retracted into the casing 262 against the urging force of the spring member 264 with the slide plunger 258, and the conical hole The cover 210 is moved while being moved away from the cover 256. At this time, the screw 252 is not removed from the first member 42, but the movement of the slide 214 with respect to the screw 252 (first member 42) is permitted by the elongated hole 250.

  The cover 210 is positioned by inserting the ball 260 into another conical hole 256 and positioning the slide 214. After positioning, the screw 252 is tightened to fix the cover 210 to the first member 42 in a direction parallel to the electric component feeding direction. In the present embodiment, the engaging pin 226 and the engaging hole 232 constitute a means for attaching the cover 210 to the slide 214, and the slide 214 and the conical hole 256, which is an engaging concave portion which is a kind of fixed engaging portion, are elastically engaged. A step position changing device 266 is configured with a ball 260 and a spring member 264 which are types of joint protrusions, and the step position changing device 266 forms a cover mounting device 268 with the shaft 218 and the elongated hole 220. Yes.

  When the cover 210 is moved so as to change its position in the direction parallel to the electric component feeding direction, the shaft 218 moves together with the cover 210 and the slide 214, so that the cover 210 is rotated around the shaft 218 at any position. It can be rotated and taping electrical components can be arranged.

  A plurality of tape guide members having different widths are attached to the first member 42 as the main body member. The sixth member 52 is one of them. An example of a sixth member constituting a tape guide member having a width different from that of the sixth member 52 is shown in FIG. Each of the sixth members 52, 269, and 271 shown in FIGS. 34 (a), (b), and (c) has a width of the groove 190 that allows the emboss 70 to pass through and a width of the mounting leg 206 (the sixth member's width). The dimensions in the direction parallel to the width direction are different, but the configuration is the same.

  In each of the sixth members 52, 269, and 271, the width of the support rail 198 provided with the support surface 202 that supports and guides the supported portion 68 on the side where the feed hole 74 of the carrier tape 64 is provided from below. All are made the same, and the relative positions in the width direction of the support rail 198 and the positioning surface 209 for positioning the sixth member in the width direction with respect to the first member 42 are all made the same. The sixth members 52, 269, and 271 have different widths of the grooves 190, different intervals between the pair of support surfaces 202 and 204, and are different from each other in a portion that guides the taping electrical component. The attachment portion to the first member 42 and the portion corresponding to the taping electric component feeding device 90 are the same, and in the width direction, portions opposite to the attachment portion and the portion corresponding to the taping electric component feeding device 90 are mutually opposite. It is different.

  Therefore, when the sixth members 269 and 271 are attached to the first member 42, the positioning surface 208 abuts on the upper surface 242 of the first member 42 as in the case of attaching the sixth member 52 to the first member 42. The mounting leg 206 is fitted into the notch 240 provided in the first member 42, the positioning surface 209 is brought into contact with the notch forming surface 244, and the bolt 246 is screwed into the first member 42. The sixth members 269 and 271 are fixed to the first member 42. In the fixed state, the positions of the sixth members 269 and 271 in the width direction of the support rail 198 and the support surface 202 with respect to the first member 42 are the same as in the sixth member 52. Therefore, the taping electric components guided by any of the sixth members 52, 269, and 271 have the same position in the width direction of the feed hole 74 with respect to the first member 42, and the taping electric component feeding device 90 will be described later. The sprocket is engaged with the feed hole 74 of the carrier tape 64, and the projection of the sprocket is engaged with the feed hole 74 of the carrier tape 64 of the taping electrical component guided by any sixth member. The taping electrical component feeder 90 can feed a plurality of types of taping electrical components having different widths.

  On the other hand, as shown in FIGS. 34B and 34C, the portions of the sixth members 269 and 271 on the side where the support rail 200 and the support surface 204 are provided protrude from the first member 42, The larger the width, the larger the protrusion amount. The width of the first member 42 is the sixth member (in this embodiment) having the smallest width among a plurality of types of sixth members (in this embodiment, the sixth members 52, 269, and 271) that are scheduled to be attached and detached. Is the same as that of the sixth member 52), and the width of the taping electrical component to be guided increases, and the width of the supply unit 32 increases as the width of the sixth member increases.

  Therefore, the sixth members 52, 269, and 271 are alternatively attached to the first member 42 according to the width of the taping electrical component, but when the width of the taping electrical component is small and the width of the supply unit 32 is small. When the supply unit 32 can be attached to the table 30 with the minimum pitch (the pitch of the two adjacent positioning grooves 56), and the width of the taping electrical component is large, it cannot be attached to the table 30 with the minimum pitch. The pitch is an integer multiple of the minimum pitch (this integer is an integer of 2 or more). If the width of the first member 42 is made the same as the width of the sixth member 271 that guides the taping electrical component having the largest width, the mounting pitch of the supply unit 32 to the table 30 even if the width of the taping electrical component is small However, when the width of the taping electrical component is small, the supply unit 32 can be attached to the table 30 without waste. Although not shown in the drawings, the sixth members 269 and 271 are similarly attached with the same cover as the cover 210, but with the same configuration but different dimensions in the width direction. It is attached to and detached from the first member 42 together with the sixth members 269 and 271. Further, the position of the cover in the direction parallel to the feeding direction of the taping electrical component is changed by the stepwise position changing device.

  For the first member 42, a plurality of types of third member 46 to fifth member 50, top cover tape processing device 92, guide roller 140, and detection head 152 of the metal detector 150 corresponding to the width of the taping electrical component are also provided. Are attached to the first member 42 alternatively according to the width of the taping electrical component. The taping electrical component feeder 90, the first member 42, and the second member 44 are shared by the sixth members 52, 269, and 271. Of the third member 46 to the fifth member 50, members that can be shared even if the width of the taping electrical component changes may be shared.

The taping electrical component feeder 90 will be described.
As shown in FIGS. 19 and 22, the first member 42 has a rotating shaft 270 perpendicular to the electric component feeding direction (a direction parallel to the width direction of the electric component supply unit 32 and the width direction of the taping electric component 62). A sprocket 272 serving as a feed member is attached so as not to be relatively rotatable. The protrusions 274 provided on the outer peripheral surface of the sprocket 272 that is circulated are engaged with feed holes 74 formed in the carrier tape 64. The sprocket 272 is provided with a ratchet wheel 276 having a diameter smaller than that of the sprocket 272 so as not to be relatively rotatable. As shown in FIG. 24, the sixth member 52 is provided with a notch 278 for avoiding interference with the sprocket 272 and the ratchet wheel 276, and the cover 210 has a carrier tape as shown in FIG. A notch 279 is formed in a portion corresponding to the feed hole 74 formed in 64, and interference with the protrusion 274 of the sprocket 272 is avoided.

  As shown in FIGS. 20 and 22, the rotating shaft 270 is attached with two reciprocating members 280 and 282 which are reciprocating members and capable of rotating relative to each other. The ratchet wheel 276 has a ring shape and is positioned and fixed concentrically to the sprocket 272 by a plurality of pins 283. As shown in FIG. 22, the rotating member 282 has a base end portion located in the same plane as the ratchet wheel 276 and is bent and raised at an intermediate portion in the longitudinal direction, and an extending end portion is connected to the rotating member 280. It is located in the same plane. The lengths of the rotary members 280 and 282, that is, the distances from the rotary axis to the extended ends are the same. The ratchet wheel may be provided integrally with the sprocket.

  On the rotating members 280 and 282, ratchet claws 284 and 286 can be rotated by pins 288 and 290 at positions where the distances from the rotation axis are equal to each other, and teeth 292 provided on the outer peripheral surface of the ratchet wheel 276 are provided. The spring members 294 and 296 provided between the rotating members 280 and 282 are urged in a direction to engage with the teeth 292. These ratchet claws 284 and 286 are engaged with the teeth 292 when the rotating members 280 and 282 are rotated in the forward direction (the counterclockwise direction in FIG. 19 is defined as the forward direction). When the state is maintained and the rotating members 280 and 282 are rotated in the reverse direction (clockwise in FIG. 19, this direction is the backward direction), the teeth 292 are overcome.

  Accordingly, when the rotating members 280 and 282 are rotated in the forward direction (forward movement), the ratchet wheel 276 is rotated in the forward direction and the sprocket 272 is rotated to send the taping electrical component 62 and rotate. When the members 280, 282 are rotated in the reverse direction (reverse movement), the ratchet pawls 284, 286 get over the teeth 292 of the ratchet wheel 276 and are ready for feeding the next taping electrical component 62. Each of the rotating members 280 and 282 performs a forward movement and a backward movement in order to feed the taping electrical component 62.

  The rotating members 280 and 282 are reciprocally rotated in opposite directions by the stepping motor 300 and the motion conversion device 302 which are rotational driving sources constituting the driving device. The stepping motor 300 is provided in the first member 42 in a direction in which the rotation axis of the rotor is parallel to the rotation axes of the rotation members 280 and 282, and is rotated at an angle proportional to the number of drive signals.

  The motion conversion device 302 includes a plate cam 306 that is a rotating cam that is a kind of cam, a bell crank lever 308 that is a cam follower, and two connecting links 310 and 312 that constitute a connecting device that is a kind of motion transmission device. The plate cam 306 has an outer peripheral surface as a cam surface 314 and is attached to the first member 42 by a shaft 316 so as to be rotatable about an axis parallel to the rotation axis of the rotation members 280 and 282. The rotation is transmitted by gears 318, 320, 322 and rotated. The cam surface 314 of the plate cam 306 has an approximately elliptical shape in which the same shape portion is formed twice in the circumferential direction. In the rotation direction of the plate cam 306, the portion where the distance from the rotation axis increases and the portion where the distance decreases are alternately provided at 90 ° intervals.

  The cam surface 314 is formed along both stationary symmetrical deformation constant velocity curves. While the plate cam 306 rotates 90 degrees, the bell crank lever 308 is accelerated, rotated at a constant speed, and decelerated. However, the momentary acceleration during acceleration and deceleration is the same in magnitude and reversed in direction. The plate cam 306 is configured to convert the constant-speed rotational motion into a motion that smoothly accelerates from the speed 0 of the bell crank lever 308, rotates at a constant speed, and then smoothly decelerates to the speed 0.

  The bell crank lever 308 is attached to the first member 42 by a shaft 324 so as to be rotatable about an axis parallel to the rotation axis of the rotation members 280 and 282, and is attached to the two arms 326 and 328, respectively. The rollers 330 and 332 thus engaged are engaged with two positions of the cam surface 314 of the plate cam 306 that are approximately 90 degrees out of phase with each other. Accordingly, the bell crank lever 308 is forcibly rotated in both the forward and reverse directions as the plate cam 306 rotates, and the two arms 326 and 328 are rotated in the same direction by the same angle. In FIG. 19, the clockwise rotation of the bell crank lever 308 is defined as forward rotation, and the counterclockwise rotation is defined as reverse rotation.

  The lengths of the two arms 326 and 328 are equal, and one end of each of the connecting links 310 and 312 is rotatably connected to a position where the distance from the rotation axis of the bell crank lever 308 of each protruding end is equal. The other ends of the connecting links 310 and 312 are rotatably connected to positions where the distances from the common rotation axis of the rotating members 280 and 282 are equal. Both end portions of the connecting links 310 and 312 are circular portions 334, and portions where the connecting links 310 and 312 of the rotating members 280 and 282 and the arms 326 and 328 are connected include a circular portion and a tapered portion. 336 is provided, the circular portion 334 is fitted into the circular portion of the notch 336, and the arms 326, 328, the connecting links 310, 312 and the rotating members 280, 282 are rotatably connected in the same plane. ing. A plurality of pressing members 338 are fixed to the first member 42 to prevent the connecting links 310 and 312 from being pulled out from the rotating members 280 and 282 and the arms 326 and 328.

  If the bell crank lever 308 is reciprocally rotated in the forward and reverse directions by the plate cam 306, the rotating members 280 and 282 are reciprocally rotated in the forward and reverse directions via the connecting links 310 and 312, respectively. The connection links 310 and 312 connect the rotation members 280 and 282 to the arms 326 and 328 so that the rotation angles are the same but the rotation directions are opposite to each other. The connecting links 310 and 312 are at right angles to the rotation members 280 and 282 and the arms 326 and 328 at the center of the rotation range of the rotation members 280 and 282 and the center of the rotation range of the arms 326 and 328, respectively. Linked in state. The length of the arms 326 and 328 (distance from the rotation axis of the bell crank lever 308 to the connection position of the connection links 310 and 312) and the length of the rotation members 280 and 282 (from the common rotation axis to the connection link 310, The distance to the connection position of 312 is the same, and the rotation angles and rotation directions of the arms 326 and 328 are the same, whereas the rotation members 280 and 282 have the same rotation angle, The direction of rotation is reversed.

  When the bell crank lever 308 is rotated in the forward direction by the rotation of the plate cam 306, the rotating member 282 is rotated in the forward direction to rotate the sprocket 272 and feed the taping electrical component 62. Meanwhile, the rotating member 280 is rotated in the opposite direction, and the ratchet pawl 284 gets over the teeth 292 of the ratchet wheel 276, and preparation for feeding is performed. When the bell crank lever 308 is rotated in the reverse direction, the rotation member 282 is rotated in the reverse direction to prepare for feeding, and the rotation member 280 is rotated in the forward direction. The sprocket 272 is rotated and the taping electrical component 62 is sent. When one of the rotating members 280 and 282 is rotated in the reverse direction and the ratchet pawl 284 gets over the teeth 292, the reverse rotation of the ratchet wheel 276 occurs when the other of the rotating members 280 and 282 is in the forward direction. This is prevented by rotating the ratchet wheel 276 in the forward direction. The ratchet wheel 276 and the ratchet pawl 284, the ratchet wheel 276 and the ratchet pawl 286 each constitute a one-way rotation transmission device, and the rotations of the rotation members 280 and 282 in the forward direction are transmitted to the sprocket 272, but in the opposite directions. This rotation is not transmitted to the sprocket 272. These two one-way rotation transmission devices share a ratchet wheel 276.

  The cam surface 314 of the plate cam 306 has a substantially elliptical shape with the same shape repeated twice, and the rotating member 280 is rotated during one rotation of the plate cam 306 as shown by the solid line in FIG. The feed operation and the feed preparation operation are performed twice. The rotation member 282 is the same, but is 90 degrees out of phase with the rotation member 280 as shown by the two-dot chain line in FIG. The rotation direction of the bell crank lever 308 changes every time the plate cam 306 rotates 90 degrees, but the rotation members 280 and 282 perform the feeding operation alternately. As described above, the cam surface 314 is formed along both stationary symmetrical deformation constant velocity curves, and the rotating members 280 and 282 smoothly change in acceleration and deceleration as shown in FIG. Then, it accelerates smoothly from speed 0 and decelerates smoothly to speed 0.

  Therefore, the inertia when the sprocket 272 and the ratchet wheel 276 are stopped is small, and the urging force of the spring members 294 and 296 that urge the ratchet pawls 284 and 286 in a direction to engage with the teeth 292 of the ratchet wheel 276 is The sprocket 272 and the ratchet wheel 276 are set so as not to rotate the ratchet pawls 284 and 286 against the urging force of the spring members 294 and 296, and the sprocket 272 and the ratchet wheel 276 are rotated. The electric component 60 of the taping electric component 62 is accurately positioned at the component supply position without rotating beyond the position given by the rotation of the members 280 and 282 in the forward direction.

  A feed pitch of the taping electrical component 62 by each feed operation of the rotating members 280 and 282 is set as a reference pitch. The reference pitch is set equal to the minimum holding pitch among a plurality of types of taping electric components having different holding pitches of the electric component 60. As described above, when the holding pitch of the electrical component 60 in the taping electrical component can be changed according to the dimensions of the electrical component 60, the holding pitch is set to M times the minimum holding pitch (M is an integer of 2 or more). Therefore, when feeding the taping electrical component 62 having the minimum holding pitch, the plate cam 306 is rotated 90 degrees to drive the sprocket 272 once, and the taping electrical component 75 having the holding pitch twice the minimum pitch is used. At the time of feeding, the plate cam 306 is rotated 180 degrees, and the sprocket 272 is driven twice. The taping electrical component 62 is a first taping electrical component, and the taping electrical component 75 is a second taping electrical component. When feeding another second taping electrical component (not shown) whose holding pitch is M times the minimum pitch (M is an integer of 2 or more), the plate cam 306 is rotated by (90 × M) degrees, and the sprocket 272 Driving is performed M times.

  The gear ratio of 318, 320, and 322 that transmits the rotation of the stepping motor 300 to the plate cam 306 is such that the plate cam 306 is rotated 90 degrees by one rotation of the stepping motor 300, and the sprocket 272 is driven once. It is set. Therefore, if the sprocket 272 is driven once, the stepping motor 300 is rotated once, and if it is driven M times, it may be rotated M times, and the stepping motor 300 can be easily controlled.

  The first member 42 is provided with a rotation stop position detector 350 that detects that the plate cam 306 is in any one of a plurality of rotation stop positions for every ¼ rotation. The rotation stop position detector 350 includes a detection plate 352 attached to the rotation shaft 316 to which the plate cam 306 is attached, and a rotation stop position detection sensor 354. The detection plate 352 is provided with four dogs 356 at equal angular intervals. The rotation stop position detection sensor 354 is a transmissive photoelectric sensor including a light emitting unit and a light receiving unit. When the plate cam 306 is in any of a plurality of rotation stop positions, the dog 356 prevents light reception by the light receiving unit. .

  In the printed circuit board assembly system 10 configured as described above, the component suction tool 22 is moved to take out the electrical component 60 from one of the plurality of supply units 32 and attach it to the printed wiring board 20. The component adsorbing tool 22 images the holding posture of the electric component 60 by the imaging device 38 after the electric component 60 is taken out and attached to the printed wiring board 20, and in the X direction and the Y direction based on the imaging data. A holding position error and a rotational position error (position error around the axis) are calculated. Prior to the mounting of the electrical component 60 on the printed circuit board 20, the reference marks provided on the printed circuit board 20 (in this embodiment, provided at two locations separated on a diagonal line) are imaged. The position error in the X direction and the Y direction is calculated for each of the plurality of component mounting positions of the printed circuit board 20, and the position error in the X direction and the Y direction of the electrical component 60 and the component mounting position and the electrical component 60 are calculated. Thus, the electrical component 60 is attached to the printed circuit board 20.

  The supply unit 32 stands by in preparation for the supply of the next electrical component 60 with the electrical component 60 taken out from the emboss 70. The empty emboss 70 is located at the component supply position. For the supply unit 32 from which the electrical component 60 is taken out by the component suction tool 22, a computer that controls the stepping motor 300 of the unit controller 500 based on an instruction from the mounting system controller 530 activates the stepping motor 300 and taping electrical components 62. To send.

  The stepping motor 300 is rotated by an amount necessary to move the electrical component 60 to the component supply position in accordance with the holding pitch of the electrical component 60 of the taping electrical component 62. For example, if the supply unit 32 supplies the electrical component 60 from the taping electrical component 62, the taping electrical component 62 has the minimum holding pitch of the electrical component 60 and is equal to the reference pitch. The plate cam 306 is controlled to rotate 90 degrees. Accordingly, one of the rotating members 280 and 282 performs a feeding operation (forward movement) to feed the taping electrical component 62 at a distance equal to the holding pitch, and a single feeding operation of the rotating member 280 or 282. The electric component 60 is moved to the component supply position by driving the sprocket 272 once. Each time the sprocket 272 is driven once, the electric components 60 are supplied one by one, and this step is a one-time feeding supply step.

  If the supply unit 32 holds the taping electrical component 75 and supplies the electrical component 60 from the taping electrical component 75, the holding pitch of the electrical component 60 is twice the reference pitch, and the stepping motor 300 has the plate cam 306. Is controlled to rotate 180 (90 × 2) degrees. As a result, the rotating members 280 and 282 alternately perform a feed operation (forward motion) one by one to drive the sprocket 272 twice, and the electric component 60 is moved to the component supply position. Each time the sprocket 272 is driven M times (twice), the electrical components 60 are supplied one by one, and this step is the M times feed supply step. A computer included in the unit controller 500 and controlling the stepping motor 300 controls the number of rotations of the stepping motor 300 according to the holding pitch of the taping electric component and feeds the taping electric component by a distance equal to the holding pitch. It constitutes a feed control means.

  When the sprocket 272 is driven once, the component adsorbing tool 22 synchronizes with the feeding of the taping electrical component by the drive, and when the sprocket 272 is driven M times, the last drive, that is, the Mth drive Is lowered in synchronism with the feeding of the taping electrical component. The descending of the component suction tool 22 is controlled by the synchronous control means, and the component suction tool 22 is parallel to at least a part of the feeding of the taping electrical component of the Mth time (the first time when the sprocket 272 is driven only once). Or it is lowered at the same time as the end of the feeding of the taping electrical component of the Mth time (the first time when the sprocket 272 is driven only once). Even when the lowering of the component adsorbing tool 22 and the M-th feeding of the taping electrical component (the first time when the sprocket 272 is driven only once) are parallel, the taping is performed before the component adsorbing tool 22 absorbs the electric component. After the feeding of the electrical component is completed, the leading electrical component is moved to the component supply position, and after stopping, the component suction tool 22 is configured to suck the electrical component. The feeding status of the taping electrical component (driving state of the sprocket 272) can be understood from the exchange of information between the mounting system controller 530 and the unit controller 500, and the lowering of the component suction tool 22 is controlled.

As described above, since the cam surface 314 of the plate cam 306 is formed along both stationary symmetrical deformation equal velocity curves, the bell crank lever 308 accelerates smoothly from the velocity 0 and rotates at a uniform velocity. Smoothly decelerates to zero speed, so that the rotating members 280 and 282 also accelerate smoothly from zero speed, rotate at a constant speed, and then smoothly decelerate to zero speed, and the taping electrical component 62 starts moving with little vibration. , Being stopped, the electric component 60 does not jump out of the emboss 70 and the posture of the electric component 60 does not change.
Further, the rotating members 280 and 282 alternately perform the feeding operation, and the sprocket 272 is driven without any breaks, so that the taping electrical component 62 is fed. Therefore, the holding pitch of the electrical components of the taping electrical component is M of the reference pitch. Even if it is double, the electrical components are supplied quickly.
The feeding of the taping electric component 62 under the control of the stepping motor 300 is performed by a computer provided in the unit controller 500, and this computer, the stepping motor drive circuit and the rotation stop position detector 350 constitute a drive source control device. .

  As described above, if the stepping motor 300 is out of step, the stepping motor 300 is further rotated to obtain a stop position signal, which is performed by the unit controller. 500 is generated by a computer for controlling the stepping motor 300 provided in 500, and a warning sound is generated when the deviation between the drive signal and the rotation position of the stepping motor due to the step-out cannot be eliminated, and the display of the abnormality content Is performed by a notification device 532 and a display device 534 provided in the component mounting system 16. The unit controller 500 gives an instruction to operate the alarm device 532 and the display device 534 to the component mounting system controller 530 via the cart controller 520.

  At the time of feeding the taping electrical component 62, the stepping motor 300 is started, and at the same time, the DC motor 408 of the top cover tape feeding device 366 is started, and the top cover tape 66 is fed while being peeled off from the carrier tape 64, and the storage box 368. Is housed in. The top cover tape feeding device 366 also serves as a top cover tape peeling device.

  When the DC motor 408 is activated, the feed gears 384 and 386 are rotated and the top cover tape 66 is fed. The top cover tape 66 is peeled off from the carrier tape 64 at the end of the notch 212 provided in the cover 210. Since it is regulated by the edge, the top cover tape 66 is peeled off as much as the carrier tape 64 is fed. The top cover tape 66 needs to be peeled off as much as the carrier tape 64 is fed, and the feed gears 384 and 386 have a larger feed amount of the top cover tape 66 than the feed amount of the carrier tape 64. It is rotated to become.

  The extra feed by the feed gears 384 and 386 is allowed by increasing the tension of the top cover tape 66 and rotating the roller holding lever 370 against the urging force of the spring member 374. Then, the DC motor 408 is stopped before the stepping motor 300, and the feed gears 384 and 386 are stopped before the feed of the carrier tape 64 is stopped. After the feed gears 384 and 386 are stopped, the roller holding lever 370 is rotated by the bias of the spring member 374 as the carrier tape 64 is fed, and the top cover tape 66 is peeled off from the carrier tape 64. While the carrier tape 64 is fed, the roller holding lever 370 adjusts the tension of the top cover tape 66, and the top cover tape 66 is fed while being peeled without sagging.

  The feed amount of the top cover tape 66 is slightly larger than the feed amount of the carrier tape 64, and the roller holding lever 370 is closer to the roller setting position arrival detection sensor 378 than the stopper member 380 due to the tension of the top cover tape 66. Therefore, even if the roller holding lever 370 is rotated by the bias of the spring member 374, the roller holding lever 370 does not come into contact with the stopper member 380, and the top cover tape 66 There is no slack. Therefore, when the taping electrical component 62 is repeatedly fed and the top cover tape 66 is repeatedly peeled and fed, the detected piece 376 provided on the roller holding lever 370 is eventually detected by the roller set position arrival detection sensor 378. To be done. As a result, the DC motor 408 is stopped, and the tension of the top cover tape 66 increases beyond the set tension and is prevented from being cut. If the taping electrical component 62 is sent even after the DC motor 408 is stopped, the roller holding lever 370 is rotated by the spring member 374, and the top cover tape 66 is peeled off while being kept in tension. When the roller holding lever 370 is rotated by the urging of the spring member 374 and the detected piece 376 is detached from the roller setting position arrival detection sensor 378, the top cover tape 66 is still being fed by the driving of the DC motor 408. If so, the DC motor 408 is restarted, the feed gears 384 and 386 are rotated, and the top cover tape 66 is fed.

  The roller set position arrival detection sensor 378 can also detect an abnormality of the top cover tape feeder 366. For example, if the DC motor 408 continues to rotate after the end of feeding of the taping electrical component 62 for some reason, the tension of the top cover tape 66 increases and the gear holding lever 370 resists the biasing force of the spring member 374. The detected piece 376 is detected by the roller setting position arrival detection sensor 378. As a result, it is understood that an abnormality has occurred in the control of the DC motor 408 or the DC motor, and the rotation of the DC motor 408 is stopped, and the operator uses the alarm device 532 and the display device 534 provided in the component mounting system 16. Appropriate processing such as notifying and displaying the occurrence of an abnormality is performed to prevent the top cover tape 66 from being cut. The control of the DC motor 408 based on the detection of the roller setting position arrival detector 379 is performed by a computer for controlling the DC motor 408 provided in the unit controller 500. A computer that controls the DC motor 408 of the top cover tape feeding device 366 of the unit controller 500 constitutes a feeding stop device.

  The top cover tape 66 thus peeled off from the carrier tape 64 and fed by the feed gears 384 and 386 flows into the storage box 368 through the inlet 472. Since the pair of feed gears 384 and 386 are engaged with each other at the teeth 388 and rotate while sandwiching the top cover tape 66, the top cover tape 66 can be reliably fed. In addition, since the scraper 436 is provided for the feed gear 386, adhesive may remain on the surface of the top cover tape 66 that has been affixed to the carrier tape 64. Even if the top cover tape 66 is stuck to the teeth 388, the top cover tape 66 is peeled off from the teeth 388 by the scraper 436, and the top cover tape 66 remains attached to the teeth 388 without causing any trouble in feeding. The surface of the top cover tape 66 with which the feed gear 384 comes into contact is the surface opposite to the side attached to the carrier tape 64 and no adhesive is attached. In addition, since the scraper 434 is provided, even if the top cover tape 66 hangs down due to weight, the scraper 434 is prevented from being peeled off from the teeth 388 of the feed gear 384 and wound around the feed gear 384.

  Further, since the exit side portions of the pair of scrapers 434 and 436 are opened about 120 degrees, the top cover tape 66 does not stick to the scrapers 434 and 436, and the storage box 368 smoothly. Sent to. The top cover tape 66 adheres to the surface of the scraper 434, 436 on the side of the top cover tape 66 and the inner surface of the storage box 368 because polytetrafluoroethylene is applied to reduce the friction coefficient. There is nothing.

  The operator can see the accumulation of the top cover tape 66 in the storage box 368 from the window 468. When the worker is full, the lid 464 is opened and the top cover tape 66 is taken out. Note that the storage box 368 may be removed from the fifth member 50 and replaced with an empty storage box 368. At this time, the top cover tape 66 is cut on the side of the feed gears 384 and 386 and inserted into a new storage box 368 attached to the fifth member 50. Alternatively, a container may be provided detachably in the container box 368 and the container may be replaced.

  When the supply of the electrical component 60 proceeds and the taping electrical component 62 wound around the supply reel 76 decreases, the worker actually moves the electrical component 60 based on the notification and display by the alarm 532 and the display device 534. Next, another taping electrical component 62 that supplies the electrical component 60 is connected to the supplied taping electrical component 62. After the taping electrical component 62 remaining on the supply reel 76 is removed from the supply reel 76 and the supply reel 76 is removed from the bucket 78, another supply reel 76 is set in the bucket 78 and is wound around the supply reel 76. The taping electrical component 62 is connected to the taping electrical component 62 that is currently supplying the electrical component 60. The connection of the two taping electrical components 62 is performed using the connection piece 100 and the connection tape 102. In the present embodiment, the taping electrical component 62 to be replenished (another taping electrical component connected to the rear end of the taping electrical component 62 fed by the taping electrical component feeder 90 and supplying the electrical component 60). 62) is a new article in which the electric component 60 has not been supplied. Notification and display by the notification device 532 and the display device 534 will be described later.

  In the computer that monitors the connection of the taping electrical component 62 of the unit controller 500, the connection monitoring process shown in FIG. 32 is executed. In this process, first, in step 1 (hereinafter abbreviated as S1, the same applies to other steps), it is determined whether or not the identification information of the taping electrical component 62 has been input. When connecting the taping electrical component 62, the operator uses the barcode reader 538 before or after the connection, and the barcode 88 of the supply reel 76 around which another connected taping electrical component 62 is wound and the taping electrical component thereof. 62 reads the barcode of the supply unit 32 that supplies the electrical component 60. The barcode of the supply unit 32 is read by pulling the movable handle member 552 from the fixed handle member 550. The barcode reader 538 is connected to the cart side controller 520, and based on the identification information about the supply unit 32, the identification information about the taping electrical component 62 supplies the electrical component 60 from the taping electrical component 62. It is supplied from the cart side controller 520 to the 32 unit controllers 500, whereby the determination result of S1 becomes YES.

  If the taping electrical component 62 is not connected and identification information is not input, the determination result in S1 is NO, S3 is executed, and it is determined whether or not the connection unit 103 is detected. This determination result is NO if the connection unit 103 is not detected, and the execution of the process ends.

  When the taping electrical component 62 is connected and identification information is input, the determination result of S1 is YES and S2 is executed, and the input identification information of the taping electrical component 62 is stored in the input identification information memory 506. At the same time, the timer time is read and stored in the identification information input time memory 508. Next, S3 is executed, but the connection position of the taping electrical component 62 is separated from the connection portion detection position where the detection head 152 is provided, and before the connection portion 103 reaches the connection portion detection position from the connection position. There is time, and the determination result of S3 is initially NO.

  Regardless of whether the operator reads the bar code or forgets to read it when connecting the taping electrical component 62, if the connecting portion 103 reaches the detection head 152, the connection piece 100 electrically connects and connects the pair of electrodes 166. The unit 103 is detected, the determination result in S3 is YES, and S4 is executed to determine whether there is identification information. This determination is made based on whether or not there is identification information in the input identification information memory 506. If the operator forgets to read the barcode even if the taping electrical component 62 is connected, there is no data in the input identification information memory 506, the determination result of S4 is NO, and S5 is executed.

  In S5, an instruction to notify and display that the operator has forgotten to read the bar code using the alarm 532 and the display device 534 and to stop the operation of the component mounting system 16 is given on the cart side. The data is output to the component mounting system controller 530 via the controller 520. As a result, the component mounting system controller 530 causes the alarm 532 to issue an alarm, and the display device 534 is wound around the supply reel 76 where the operator has forgotten to read the barcode or the barcode has not been read. The type of the supply unit 32 to which the electrical component 60 is supplied from the taping electrical component 62 is displayed. The type of the supply unit 32 can be recognized by which unit controller 500 is instructing display on the display device 534. The component mounting system controller 530 stops the operation of the component mounting system 16.

After execution of S5, the process ends and S1 is executed. And if an operator reads a barcode and identification information is input, the determination result of S1 will be YES, and S3 will be performed after S2 is performed. If the component mounting system 16 is restarted after reading the bar code, a connection detection signal is artificially issued, the determination result in S3 is YES, and S4 is executed. In this case, since the identification information is input, the determination result in S4 is YES, and the steps after S6 are executed. The component mounting system 16 is normally restarted after reading the barcode, and the determination result of S1 and S3 is NO until the identification information is input and the component mounting system 16 is restarted. S1 and S3 are repeatedly executed.
In this way, it is determined whether or not the identification information is input along with the connection of the taping electrical component 62, and the electrical component 60 is not attached to the printed wiring board 20 until the identification information is input. By doing so, it is possible to avoid an installation error caused by the electrical component 60 being supplied from the taping electrical component 62 whose type is not confirmed.

  If the determination result in S4 is YES, S6 is executed. In S6, the time of the timer is read and stored in the connection detection time memory 510, and then the time stored in the identification information input time memory 508 is subtracted from the time stored in the connection detection time memory 510 in S7. Whether or not the difference is within the set time is determined. S7 is executed when the determination result of S4 is YES, S2 is always executed, and the difference between the two times is compared with the set time.

  The time when the identification information is input and the time when the connection portion is detected are stored, and the difference between the two is compared with the set time, so that the identification information that is not input with the connection of the taping electrical component 62 is excluded This is to prevent the input from being made despite the absence of input of identification information associated with the connection of the taping electrical component. The connection portion detection position is separated from the connection position of the taping electrical component 62, and there is time until the connection portion 103 reaches the connection portion detection position from the connection position. This connection portion arrival time is the distance between the connection position and the connection portion detection position (the length of the taping electrical component 62 between the connection piece 100 and the detection head 152 at the time of connection), the electrical component 60 of the taping electrical component 62 It can be estimated from the holding pitch, the supply pace of the supply unit 32 that supplies the electric component 60 from the taping electric component 62, that is, whether or not a plurality of electric components 60 are supplied continuously. Therefore, if the set time is set to a time slightly longer than the connection portion arrival time, the taping electrical component 62 is connected and identification information is input, and if the connection portion 103 is detected within the set time, the input is made. It can be said that the identification information is information input along with the connection. The set time is a length that can be said that the input identification information is the information input along with the connection even when the barcode is read prior to the connection work when the taping electrical component 62 is connected. Set to

  On the other hand, there is a problem when the connection unit 103 is not detected within the set time. In this system 10, after the mounting on the printed wiring board 20 on the electrical component 60 is started, if the barcode of the supply reel 76 is read for any reason other than the connection of the taping electrical component 62, The determination result of S1 is YES, the time is read in S2, and the identification information is stored in the input identification information memory 506. Thereafter, if the operator does not forget to read the barcode when connecting the taping electrical component 62, the identification information input in S2 is stored in the input identification information memory 506 in place of the identification information stored previously. Therefore, there is no hindrance. However, if the operator forgets the input, the identification information not associated with the connection of the taping electrical component 62 is still stored in the input identification information memory 506, and as a result, the determination result in S4 becomes YES. However, in this case, since the input of the identification information is performed before the connection of the taping electrical component 62 and the time from the input of the identification information to the detection of the connection unit 103 exceeds the set time, The determination is NO, and it can be seen that the input identification information is identification information that is not input along with the connection.

  If the determination result in S7 is NO, S8 is executed, the data stored in the input identification information memory 506 is erased, and the identification information has been input, but it is not an input accompanying the connection of the taping electrical component 62, A notification that the reading of the barcode accompanying the connection has not been performed, a display, and an instruction to stop the operation of the component mounting system 16 are output to the component mounting system controller 530 via the cart side controller 520. After the execution of S8, the process ends. Thereafter, the barcode is not read, and the process is executed as in the case where the determination result of S4 is NO.

  If the time from the input of the identification information to the detection of the connection unit 103 is within the set time, the determination result in S7 is YES and S9 is executed, and the identification information regarding another connected taping electrical component 86 is input. A determination is made as to whether or not the identification information is to be matched. The identification information to be input is supplied from the host computer 540 side and stored in the reference identification information memory 504. If the contents of both do not match, the type of the taping electrical component 62 to be connected is different. It can be seen that the taping electrical component 62 is connected. As a result, the determination result in S9 is NO, S10 is executed, and mismatch information indicating that the identification information is mismatched is created. The mismatch information includes data indicating that the wrong taping electrical component 62 is connected, data indicating the supply unit 32 to which the incorrect taping electrical component 62 is connected, identification information of the taping electrical component 62 to be connected, and incorrect information. The identification information of the taping electrical component 62 connected to each other is included. Next, S11 is executed, the identification information stored in the input identification information memory 506 is erased, the fact that the wrong taping electrical component 62 is connected is notified using the notification device 532, and the mismatch information is displayed on the display device 534. The display and the instruction to stop the operation of the component mounting system 16 and the mismatch information created in S10 are output to the component mounting system controller 530 via the cart controller 520.

  If the taping electrical component 62 to be connected is connected, the identification information matches, the determination result in S9 is YES, and S12 is executed. In S12, the count value C of the remaining amount counter 512 is equal to the number of electrical components 60 included in the connected taping electrical component 62, and the number of electrical components 60 positioned between the connection detection position and the component supply position. Is set to the value added. The distance between the connection detection position and the component supply position is known in the design of the supply unit 32, and based on this distance and the holding pitch of the electrical component 60 of the taping electrical component 62, the distance between both positions is known. The number of electrical components 60 located at is calculated. Further, after it is determined whether or not the identification information input in S9 matches the reference identification information, the identification information is unnecessary in this connection monitoring process, and is stored in the input identification information memory 506. The identification information is erased.

Next, S13 is executed, and it is determined whether or not one electrical component 60 has been supplied, that is, whether or not the component suction tool 22 has taken out one electrical component 60 from the emboss 70. This determination is made based on information from the component mounting system controller 530 that controls the suction operation of the component suction tool 22. If one electrical component 60 is supplied, the determination result in S13 is YES, S14 is executed, and the count value C of the remaining amount counter 512 is decreased by one. Next, S15 is executed, and it is determined whether or not the remaining amount C is equal to or less than the set number C _S. A determination is made as to whether or not the electrical component 60 held by the taping electrical component 62 has become small. This determination result is initially NO, and S13 is executed.

S13 to S15 are repeatedly executed until the determination result of S15 is YES. If the remaining amount of the electrical component 60 is reduced and the count value C of the remaining amount counter 512 is equal to or less than C _S , the determination result of S15 is YES and S16 is executed, and the remaining number of electrical components 60 is reduced. An instruction to notify and display is output to the mounted system controller 530 via the cart side controller 520. Based on this information, the alarm 532 emits an alarm sound to prompt the worker to replenish the taping electrical component 62, and the display device 534 informs the worker that the taping electrical component 62 should be replenished and that the taping electrical component 62 is reduced. The type of the supply unit 32 and the type of taping electrical component 62 to be connected are displayed. After the output of this instruction, S17 is executed, the count value C of the remaining amount counter 512 is reset, and the process ends.

  In the above-described embodiment, the main body member has the same mold, but a plurality of tape guide members for guiding a plurality of types of taping electric parts having different widths are attached. A plurality of tape guide members for guiding parts may be attached to the main body member.

  For example, the main body member 702 of the supply unit 700 shown in FIG. 35 has a tape guide member 704 for an embossed carrier type taping electrical component that guides the embossed carrier type taping electrical component (see FIGS. 37 and 38. Hereinafter, an embossed carrier guide). And a tape guide member 706 for punch carrier type taping electrical parts for guiding the punch carrier type taping electrical parts (refer to FIGS. 39 and 40, hereinafter referred to as punch carrier guide members 706). ing. The supply unit 700 is configured to hold two taping electric components and supply electric components alternatively from the taping electric components. The types of these two taping electrical components are the same, and two embossed carrier guide members 704 or punch carrier guide members 706 are fixed side by side in the width direction of the main body member 702.

  As shown in FIGS. 35, 37, and 38, the emboss carrier guide member 704 is formed in a columnar shape, extending in the longitudinal direction, and formed with a groove 842 that allows the taping electrical component to pass through the emboss. The groove walls that define the grooves 842 constitute the support rails 844 and 846, and the upper end surfaces of the support rails 844 and 846 respectively support the support surfaces 848 and 850 that support and guide the supported portion of the taping electrical component from below. It is composed. The bottom surface of the groove 842 and the front portions of the support surfaces 848 and 850 are inclined downward toward the front to form guide surfaces 852, 854, and 856. To the tape cutter 496 side. In addition, the width of the front portion of the seventh member 816 is narrowed toward the tip.

  As shown in FIG. 37, two positioning holes 860 and 862 are formed in the embossed carrier guide member 704 at two locations separated in the longitudinal direction. The positioning hole 860 on the front side, that is, on the downstream side in the electric component feeding direction, has a circular cross section and has a stepped shape, and has a large diameter hole 864 and a small diameter hole 866. The positioning hole 862 on the rear side, that is, the upstream side in the electric component feeding direction also has a stepped shape, and includes a counterbore portion 868 having a long hole shape or a circular hole shape, and a long hole portion 870. The dimension of the long hole portion 870 is the same as the diameter of the small-diameter hole portion 866 of the positioning hole 860 in the direction perpendicular to the electric component feed direction (the direction parallel to the width direction of the taping electric component). In the parallel direction, it is longer than that.

  Although not shown, the punch carrier type taping electrical component includes a carrier tape composed of a base tape and a bottom cover tape in which a plurality of through holes penetrating in the thickness direction are provided at equal intervals, and a lower opening of the through hole. The upper opening of the electrical component housing recess formed by being closed by the bottom cover tape is covered with the top cover tape. The bottom cover tape and the top cover tape are attached so as to block the openings at the lower and upper portions of the through hole of the base tape and leave one edge parallel to the longitudinal direction of the base tape. A plurality of feed holes are formed at an equal pitch. This pitch is the same as the pitch of the feed holes 74 provided in the carrier tape of the embossed carrier type taping electrical component, and, similar to the embossed carrier type taping electrical component, the sprocket of the taping electrical component feeding device is placed in the feed hole. And the punch carrier type taping electrical component is fed by the rotation of the sprocket.

  As shown in FIGS. 39 and 40, the punch carrier guide member 706 does not have a groove 842 that allows the emboss to pass through, and the entire upper surface thereof supports the bottom cover tape of the punch carrier type taping electrical component from below. The embossing carrier guide member 704 is configured in the same manner as the embossing carrier guide member 704 except that the supporting surface 710 is guided, and components having the same functions are denoted by the same reference numerals. The height of the support surface 710 of the punch carrier guide member 706 is set such that the height of the upper surface of the taping electrical component supported by the support surface 710 is attached to the main body member 702 when the punch carrier guide member 706 is attached to the main body member 702. The size is set to be the same as the height of the upper surface of the supported portion of the carrier tape supported by the support surfaces 848 and 850 of the embossed carrier guide member 704. The heights of the support surface 710 and the support surfaces 848 and 850 from the upper surface of the main body member 702 are different.

  A downstream portion of the support surface 710 in a direction parallel to the electric component feeding direction is a guide surface 712 that is inclined downward toward the downstream side, and guides the carrier tape to the tape cutter side. Further, the front end portion of the punch carrier guide member 706 is narrower toward the front end. Further, a vibration absorbing material 713 is embedded in a portion corresponding to the component supply position of the punch carrier guide member 706. The vibration absorbing material 713 is made of, for example, a damping rubber having a vibration suppressing function or a foamed material such as a sponge. The electric component sent to the component supply position is located on the vibration absorbing material 713, and the shock when the component adsorbing tool comes into contact with the electric component is absorbed by the vibration absorbing material 713, so that damage to the electric component is avoided.

  The emboss carrier guide member 704 and the punch carrier guide member 706 are alternatively fixed to the main body member 702 depending on whether the taping electrical component held in the supply unit 700 is an emboss carrier type or a punch carrier type. Thus, the tape guide portion 708 is configured. These guide members 704 and 706 are positioned on the main body member 702 by two positioning bolts 872, fixed and mounted. Therefore, as shown in FIG. 41, positioning holes 874 are formed in the body member 702 at two locations separated in a direction parallel to the electric component feeding direction, and female screw holes 876 are formed in the back of each positioning hole 874. Are formed coaxially with each other. The diameter of the positioning hole 874 is the same as the diameter of the small-diameter hole portion 866 of the positioning hole 860 provided in the emboss carrier guide member 704 and the punch carrier guide member 706, respectively. Further, as shown in FIG. 42, one of the two positioning bolts 872 is opposite to the positioning shaft portion 878, the male screw portion 880 screwed into the female screw hole 874, and the male screw portion 880 side of the positioning shaft portion 878. A head 882 provided at the end on the side is provided. The diameter of the positioning shaft portion 878 is set to be a size that allows the small-diameter hole portion 866 and the positioning hole 874 of the positioning hole 860 to be fitted with substantially no gap.

  As shown in FIGS. 35 and 36, the main body member 702 is provided with a cover 890 that prevents the taping electrical components from lifting from the guide members 704 and 706. The cover 890 has a U-shaped cross-sectional shape, and tapers 89 are attached to the body member 702 by shafts 894 at the leg portions 892 provided at the rear portions (upstream side in the electric component feeding direction) of both side walls of the U shape. It is attached so as to be rotatable around an axis parallel to the width direction of the electrical component.

  The cover 890 is engaged with the main body member 702 by the engaging member 900 at the front portion (downstream side in the electric component feeding direction). The engaging member 900 has a U-shaped cross section, is fitted to the front part of the embossing carrier guide member 704 or the punch carrier guide member 706, and extends from a pair of U-shaped side walls 901. The leg portion 902 is fitted to the front portion of the main body member 702, and is attached by a shaft 904 so as to be rotatable about an axis parallel to the rotation axis of the cover 890. Further, the hole into which the shaft 904 of the leg 902 is fitted is a long hole 906 that is long in a direction perpendicular to the rotation axis, and the engaging member 900 can be moved with respect to the shaft 904.

  Each of the pair of U-shaped side walls of the engaging member 900 is provided with an engaging claw portion 910 on a portion opposite to the portion on which the leg portion 902 is provided, and is provided on the cover 890. It is fitted into the engaging recess 912 and is engaged with the lower portion of the inner surface of the engaging recess 912. The engaging member 900 is engaged with an engaging claw by a spring member 918 which is an elastic member which is a kind of urging means provided between a tongue piece 916 provided between a pair of legs 902 and a main body member 702. The portion 910 is biased in a direction to engage with the engaging recess 912. As a result, the cover 890 is biased in a direction approaching the main body member 702, and the front portion of the U-shaped bottom wall 920 of the cover 890 is guided by the emboss carrier guide member 704 or the punch carrier guide member 706. The upper surface of the electrical component is contacted and pressed against the guide members 704 and 706 to prevent the floating from the support surfaces 848, 850, and 710. The front part of the bottom wall 920 of the cover 890 forms a contact part.

  The supply unit 700 includes two sets of taping electrical component feeding devices 714. Each taping electrical component feeder 714 has the same configuration. The taping electric component feeding device 714 includes a sprocket 716 as a feeding member. The electric motor (not shown) is used as a driving source, and the rotation of the electric motor is rotated by a motion conversion device including a cam, a cam follower, a lever and a link. The ratchet wheel 720 is rotated in the forward direction (counterclockwise in FIG. 35) based on the rotation of the rotation member 718, and the sprocket 716 is rotated to send the taping electrical component. Since the configuration of the taping electrical component feeding device 714 is not directly related to the understanding of the present invention, detailed drawings and explanations are omitted. The emboss carrier guide member 704 and the punch carrier guide member 706 have a notch 722 for avoiding interference with the sprocket 716, the ratchet wheel 720 and the rotating member 718, respectively, as shown in FIGS. , 724, 726 are provided.

  The attachment of the emboss carrier guide member 704 to the main body member 702 will be described. At the time of attachment, the engaging member 900 is removed from the cover 890, the cover 890 is rotated around the axis of the shaft 894, and is retracted from the portion where the guide member 704 or 706 of the main body member 702 is fixed. The engaging member 900 is rotated around the shaft 904 while being moved against the urging force of the spring member 918, the engaging claw portion 910 is pulled out of the engaging recess 912, and the cover 890 is rotated.

  Then, the emboss carrier guide member 704 is placed on the main body member 702, and the male screw portion 880 of the positioning bolt 872 passes through the front positioning hole 860 among the two positioning holes 860 and 862 of the emboss carrier type guide member 704. Is inserted into the front positioning hole 874 and screwed into the female screw hole 876. The positioning shaft portion 878 of the positioning bolt 872 is fitted over both the positioning hole 874 provided in the main body member 702 and the small diameter hole portion 866 of the positioning hole 860 provided in the guide member 704, and the main body The member 702 and the embossed carrier guide member 704 are positioned relative to each other. The positioning bolt 872 is screwed until the head 882 contacts the bottom surface of the large-diameter hole 864 of the positioning hole 860.

  Next, the male screw portion 880 of the positioning bolt 872 is inserted into the rear positioning hole 874 of the main body member 702 through the rear positioning hole 862 of the emboss carrier guide member 704 and screwed into the female screw hole 876. . Since the long hole portion 870 of the positioning hole 862 is longer than the diameter of the small diameter hole portion 866 of the positioning hole 860, that is, the diameter of the positioning hole 874 in the direction parallel to the electric component feeding direction, Even if there is a positional shift in a direction parallel to the electric component feeding direction, the male screw portion 880 of the positioning bolt 872 can be screwed into the female screw hole 876. Further, the width of the long hole portion 870 is the same as the diameter of the small diameter hole portion 866, and the positioning shaft portion 878 of the positioning bolt 872 is fitted over the positioning hole 874 and the long hole portion 870. Thus, the main body member 702 and the embossed carrier guide member 704 are positioned in the width direction, and the rotation of the guide member 704 relative to the main body member 702 is prevented. The positioning bolt 872 is screwed until the head portion 882 contacts the bottom surface of the counterbore portion 868, and the embossed carrier guide member 704 is positioned, fixed, and mounted on the main body member 702 in the horizontal plane. Further, the positioning of the emboss carrier guide member 704 in the direction perpendicular to the main body member 702, that is, the direction perpendicular to the width direction and the longitudinal direction, is performed by the upper surface of the main body member 702 and the bottom surface of the emboss carrier guide member 704. These top and bottom surfaces are positioning surfaces parallel to the width direction of the taping electrical component and the feeding direction of the electrical component.

  When the emboss carrier guide member 704 is fixed to the main body member 702, the emboss of the taping electrical component is fitted into the groove 842, the pair of supported portions are placed on the support surfaces 848 and 850, and the feed hole is formed on the sprocket 716. After engaging with the protrusion, the cover 890 is rotated so as to cover the embossed carrier guide member 704 and the taping electrical component, and the engaging member 900 is engaged with the cover 890. The engaging member 900 is rotated while being moved against the urging force of the spring member 918, and the engaging claw portion 910 is fitted into the engaging concave portion 912. When the force applied to the engagement member 900 is released, the engagement claw portion 910 is engaged with the lower surface inside the engagement recess 912, and the cover 890 approaches the emboss carrier guide member 704 by the spring member 918. The front portion of the cover 890 (downstream in the electric component feeding direction from the engaging portion of the carrier tape and the projection of the sprocket 716) comes into contact with the upper surface of the taping electric component, and the supported portion Is pressed against the support surfaces 848 and 850 to prevent the lift from the support surfaces 848 and 850. The embossed carrier-type taping electrical component is positioned in the width direction by positioning the emboss by the pair of groove side surfaces of the groove 842, or the pair of supported parts are positioned by the pair of U-shaped side walls of the cover 890. Thus, the positioning is performed in the width direction.

  When supplying an electrical component by the punch carrier type taping electrical component in the supply unit 700, the emboss carrier guide member 704 is replaced with a punch carrier guide member 706. At the time of replacement, the engaging member 900 is removed from the cover 890, the cover 890 is rotated and retracted from the guide member 704, the two positioning bolts 872 are removed, and the embossed carrier guide member 704 is removed from the main body member 702. remove.

  Next, the punch carrier guide member 706 is placed on the main body member 702, and the two positioning bolts 872 and the positioning holes 860, 862, and 874 are used in the same manner as when the embossing carrier guide member 704 is mounted on the main body member 702. The body member 702 is positioned and fixedly mounted. After fixing, the punch carrier type taping electrical component is placed on the support surface 710 of the punch carrier guide member 706, and then the cover 890 is rotated to cover the punch carrier guide member 706 and the punch carrier type taping electrical component. The joining member 900 is engaged. In the case of the punch carrier guide member 706, the pair of U-shaped side walls of the cover 890 prevent the positional deviation of the taping electrical component in the width direction and is positioned in the width direction. Further, the front portion of the bottom wall 920 of the cover 890 contacts the upper surface of the taping electrical component and presses against the support surface 710 to prevent lifting. When the emboss carrier guide member 704 and the punch carrier guide member 706 are attached to the main body member 702 to guide the taping electrical component, the height of the top surface of the emboss carrier type taping electrical component and the top surface of the punch carrier type taping electrical component are They are formed so as to have the same height, and the common cover 890 prevents the different types of taping electrical components from being lifted from the guide members 704 and 706 well.

  Taping electrical components of different types may be guided by a common tape guide member. In this case, for example, a cover 730 shown in FIG. 43 is used. In the supply unit 732 including the cover 730, the cover 730 is attached to the main body member 702 by a shaft 894 so as to be rotatable about an axis parallel to the width direction of the taping electrical component, similar to the cover 890. The combined member 900 is engaged and urged by the spring member 918 in a direction approaching the main body member 702.

  The cover 730 has a U-shaped cross section, and as shown in FIG. 43, an engagement portion of the taping electrical component with the taping electrical component feeder 714, that is, the sprocket 716, of the U-shaped bottom wall 734. The part on the upstream side in the electric component feeding direction is bent and raised to the taping electric component side (tape guide member side) with respect to the portion where the projection of the carrier is engaged with the carrier tape feed hole. A leaf spring 736 that can be elastically deformed (in a direction toward and away from the bottom wall 734 of the cover 730) is provided integrally with the cover 730.

  As shown in FIG. 44, an emboss carrier guide member 704 is fixed to the main body member 702. The emboss carrier guide member 704 guides both the emboss carrier type taping electrical component 740 (see FIG. 46) and the punch carrier type taping electrical component 742 (see FIG. 47). When the embossed carrier-type taping electrical component 740 is guided, as shown in FIG. 46, a pair of supported portions (the same reference numerals as the supported portions 68 of the taping electrical component 60 of the above embodiment) 68 are provided on the support surface 848. , 850, and the emboss 70 is inserted into the groove 842. When the punch carrier taping electrical component 742 is guided, as shown in FIG. 47, the punch carrier taping electrical component 742 has both edges extending parallel to the longitudinal direction on the support surfaces 848 and 850. And supported and guided from below.

  Since the thickness of the supported portion 68 of the embossed carrier type taping electrical component 740 is smaller than the thickness of the punch carrier type taping electrical component 742 (the sum of the thickness of the carrier tape and the thickness of the top cover tape), the embossed carrier guide When the member 704 is shared by the embossing carrier type taping electrical component 740 and the punch carrier type taping electrical component 742, the height of the upper surface of the punch carrier taping electrical component 742 from the support surfaces 848 and 850 is higher for the embossing carrier. The height of the upper surface of the taping electrical component 740 (the surface including the upper surface of the supported portion) from the support surfaces 848 and 850 becomes higher.

  Therefore, when the embossed carrier type taping electrical component 740 is guided, as shown in FIGS. 44 and 48, the forward tilt of the cover 730 increases, and the cover 730 and the cover 730 become closer to the rotational axis side of the cover 730. The distance to the embossed carrier type taping electrical component 740 is increased. In FIG. 48, the forward tilted state of the cover 730 is shown exaggerated from the actual state. However, the cover 730 is provided with a leaf spring 736 that contacts the embossed carrier-type taping electrical component 740 and presses the supported portion 68 against the support surfaces 848 and 850 to lift from the support surfaces 848 and 850. To prevent. The embossed carrier-type taping electrical component 740 is in contact with the front portion of the bottom wall 734 of the cover 730 and pressed against the support surfaces 848 and 850 on the downstream side of the engaging portion that engages with the protrusion of the sprocket 716, and the upstream side In this case, the leaf spring 736 contacts and presses against the support surfaces 848 and 850, and the lifting of the taping electrical component 742 from the support surfaces 848 and 850 is reliably prevented. The front portion of the bottom wall 734 of the cover 730 and the leaf spring 736 each constitute a contact portion.

  When the emboss carrier guide member 704 guides the punch carrier type taping electrical component 742 as shown in FIG. 47, since the punch carrier type taping electrical component 742 is thick, the cover 730 is tilted forward as shown in FIG. The leaf spring 736 is elastically deformed toward the bottom wall 734 side to allow the punch carrier type taping electrical component 742 to pass through, and is in contact with the punch carrier type taping electrical component 742 and pressed against the support surfaces 848 and 850. And lifting from the support surfaces 848 and 850 is prevented. The cover 730 contacts the sprocket 714 of the punch carrier type taping electric component 742 on both the upstream side and the downstream side in the electric component feeding direction, and prevents the lift from the support surfaces 848 and 850. is there.

When the tape guide member is shared by taping electrical components of different molds, the punch carrier type taping electrical component is placed on the support surface of the punch carrier guide member and the bottom cover tape is supported from below and guided. Alternatively, an embossed carrier-type taping electrical component may be mounted on the emboss and supported by the bottom surface of the emboss.
If a cover having a leaf spring is used in the same manner as the cover 730, it corresponds to the difference in the height of the upper surface of the taping electrical component due to the difference in the type of the taping electrical component, It can be made to contact in two places, the upstream side and the downstream side, of the engaging portion, and can be prevented more reliably.
When the tape guide member is shared for taping electrical components of different types, the cover may be attached to the main body member or attached to the tape guide member. If the main body of the supply unit cannot be divided into a main body member and a tape guide member, the cover is attached to the main body.

  Further, like the cover 730, a cover having a contact portion that contacts the upper surface of the taping electrical component on the upstream side and the downstream side of the engaging portion of the taping electrical component with the taping electrical component feeding device is a type of the taping electrical component. A dedicated tape guide member may be used in a supply unit mounted on the main body member. For example, in the embodiment shown in FIGS. 35 to 42, the emboss carrier guide member 704 and the punch carrier guide member 706 have the same mold, but the thickness (in the case of a punch carrier type taping electrical component, the carrier). When the tape thickness is the sum of the thickness of the top cover tape and the thickness of the supported part in the case of embossed carrier type taping electrical components) Whereas the height of the upper surface of the taping electrical component from the support surface varies depending on the thickness of the taping electrical component, the cover 730 allows the cover to be attached to the taping electrical component regardless of the thickness of the taping electrical component. In contact with the taping electrical component feeding device, the upstream side and the downstream side are in contact with each other in the electrical component feeding direction. Lifting from the support surface can be prevented Te.

Alternatively, the embossed carrier guide member and the punched carrier guide member have different configurations for guiding the taping electrical parts, but have the same shape and dimensions, and when the embossed carrier guide member is fixed to the main body member, the embossed carrier guide When the height of the pair of support surfaces from the upper surface of the main body member and the height of the support surface of the punch carrier guide member from the upper surface of the main body member are the same, Since the thickness of the supported portion is smaller than the thickness of the taping electrical component for the punch carrier, the punch guided by the punch carrier guide member is higher than the upper surface of the embossing carrier taping electrical component guided by the embossing carrier guide member. The upper surface of the carrier taping electrical component is higher, but is similar to the cover 730. With the bar, it is possible to absorb the difference in height of the upper surface due to the difference in the type of tape electrical components (thickness).
When the support surfaces of the tape guide members for the emboss carrier and punch carrier are made uniform, the difference in thickness due to the difference in mold (thickness difference in the same mold may be absorbed) When absorbed by the spring and having different heights, the difference in thickness in the same mold is absorbed by the leaf spring.

  Furthermore, in the embodiment shown in FIGS. 35 to 42, two tape guide members of the same type are attached to the main body member. However, two tape guide members of different types are attached to the main body member. The electric unit may be supplied from two types of taping electric components having different types by the supply unit.

  Further, the selective attachment of a plurality of types of tape guide members for guiding taping electrical components of different types to a common main body member is not limited to a supply unit that supplies electrical components from two taping electrical components. It can also be performed in a supply unit that supplies electrical components from a single taping electrical component. In this case, for each of the plurality of types of tape guide members, a plurality of types of tape guide members having different widths of the guide portions for guiding the taping electrical components are prepared to cope with differences in the widths of the taping electrical components. Good.

Further, in each of the above embodiments, the taping electric component feeding device converts the rotation of the stepping motor, which is a rotational drive source, into a reciprocating rotational motion of two rotational members by a motion conversion device including a cam and a cam follower. Although the forward movement of the moving member is transmitted to the sprocket as the feeding member by the one-way rotation transmission device, the feeding device is not limited to such a configuration, and various configurations can be adopted. For example, a double-acting fluid pressure cylinder such as a double-acting air cylinder, which is a kind of reciprocating drive source, which converts the reciprocating motion of the reciprocating driving member into the rotational motion of the rotating member by means of a motion converter and transmits it Alternatively, the rotating member may be rotated based on the driving force of a driving source provided separately from the supply unit, and the taping electrical component may be sent to the feeding member. These may or may not include a speed control cam and cam follower.
Further, the taping electrical component feeder is not limited to having two rotating members, but may include only one rotating member.
It is good also as what was provided in. Further, the feed member is not limited to a sprocket. For example, the feed member is a belt that is wound around two or more pulleys and circulates as the pulleys rotate. It is good also as a feed belt provided with the protrusion engaged with.

  Further, the cover may be provided on the main body so as to move in conjunction with the feeding of the taping electrical component, and when the taping electrical component is fed, the cover may be moved together with the taping electrical component while covering the leading electrical component. . When taking out the electrical component from the carrier tape, the cover is retracted from the electrical component located at the component supply position.

  Furthermore, the table on which the supply unit is mounted in each of the above embodiments is configured to supply the electrical component to the component adsorber by fixing the position when the electrical component is attached to the printed wiring board. The table moving device may be moved along a line along which a plurality of supply units are arranged, and each component supply unit of the plurality of supply units may be sequentially moved to the component supply position. The component supply position is a position in the movement path of the plurality of component supply units.

  Further, in each of the above-described embodiments, the supply units 32 and 600 have the next electrical component 60 in a state where the empty emboss 70 is located at the component supply position after the electrical component 60 is taken out from the emboss 70 by the component suction tool 22. However, it is also possible to wait in a state where the electrical component is sent to the component supply position. The taping electrical component is sent immediately after the electrical component is removed from the emboss.

  Further, the processing of the top cover tape 66 peeled off from the carrier tape 64 is not limited to being accommodated in the accommodation box 368 but may be wound on a take-up reel or guided to the accommodation space by a conduit or the like. It may be.

  In the embodiment, the position of the cover 210 in the direction parallel to the electric component feeding direction is changed in a plurality of stages, and the cover 210 is fixed to the first member 42 by the fixing means in the direction parallel to the electric component feeding direction. However, it is not indispensable to fix the cover 210 to the first member 42, and it may only be positioned by the conical hole 256 and the ball plunger 258. At this time, a stepped screw is used in place of the screw 252 for fixing the slide 214 to the first member 42, and the slide 214 is allowed to move while being prevented from being lifted from the first member 42. The screw includes a shaft portion, one end portion of the shaft portion, a head portion having a larger diameter than the shaft portion, a screw portion provided on the other end portion of the shaft portion and having a smaller diameter than the shaft portion, and a sixth member The first member 42 is screwed through the through hole 248 provided in the hole 52 and the long hole 250 provided in the slide 214. The shaft portion has a length that allows the slide 214 to be movably sandwiched between the head and the first member 42, and prevents the lift from the first member 42 by the head. The slide 214 is moved in a state where the first screw 42 is screwed to the first member 42, and the position of the cover 210 in the direction parallel to the electric component feeding direction is changed.

  Further, in each of the embodiments shown in FIGS. 35 to 48, the cover is attached to the main body by a cover attaching device that attaches the cover so that the position in the direction parallel to the feeding direction of the taping electrical component by the taping electrical component feeding device can be changed. The position in the direction parallel to the electric component feeding direction may be changed.
