Description

The present invention relates to a reel support device attached to a parts supply unit that draws in a carrier tape wound around a reel and supplies parts stored in the carrier tape, and a parts mounting device provided with the reel support device.

Conventionally, as a component supply unit provided in a component mounting device for mounting components on a substrate, a tape feeder that conveys a carrier tape containing components and supplies the components to a component take-out position is known. The tape feeder generally loads the carrier tape manually, and when the carrier tape runs out of parts, splices the beginning of the subsequent carrier tape to the end of the preceding carrier tape to replenish the parts. In recent years, an auto-load type that automatically pulls in and conveys carrier tape has also been used. In such an autoload type tape feeder, the subsequent carrier tape can be inserted into the tape insertion slot of the tape feeder during the supply operation of the parts by the preceding carrier tape, and the end portion of the preceding carrier tape can be inserted. When it is detected that the tape has passed a predetermined position in the tape feeder, the subsequent carrier tape is automatically pulled in and loaded. Therefore, parts can be replenished without splicing the carrier tape as in the conventional case.

By the way, the carrier tape supplied to the tape feeder is wound around the reel core, and the reel is supported by a reel support device attached to the tape feeder. The tape feeder pulls in the carrier tape from the reel supported by the reel support device and conveys it. As the supply of parts by the tape feeder progresses, the remaining amount of carrier tape wound around the reel core gradually decreases, and finally the end of the carrier tape comes off the core and the reel becomes empty. .. Reel replacement in the component mounting device is performed by ejecting such an empty reel from a place where the reel was previously supported and installing a new reel at the ejected place.

The empty reel is usually ejected manually in such a reel exchange, but it is also known that the reel is automatically ejected (see, for example, Patent Document 1 below). .. This is because the carrier tape is pulled out from the reel by the carrier tape being pulled in by the tape feeder, and the radius of the carrier tape wound around the reel core (the center of rotation of the outermost carrier tape wound around the core). This is based on the fact that the distance from the reel gradually decreases, and the reel does not pass (fall) through the discharge port (fall) while the amount of carrier tape wound around the reel is above a certain level. When the amount of carrier tape wrapped around the reel falls below a certain level, the reel core passes through the discharge port.

However, in the above-mentioned conventional one, the reaction force that supports the weight of the reel including the carrier tape acts intensively on the portion of the carrier tape wound around the reel that is in contact with the edge of the discharge port. There was a risk of damage or deformation of the parts stored in the carrier tape at that part. In particular, the reel around which the carrier tape containing the large parts is wound has a large weight as a whole, so that the risk of damage or deformation of the parts is even greater.

Therefore, an object of the present invention is to provide a reel support device capable of automatically ejecting an empty reel without causing damage or deformation to the parts housed in the carrier tape, and a component mounting device provided with the reel support device. To do.

The reel support device of the present invention is a reel support device attached to a parts supply unit that draws in a carrier tape wound around a reel core and supplies parts stored in the carrier tape, and is in a vertical position. A reel passage that has a support portion that supports the outer peripheral edge of the reel and one end of the support portion is a drop end for dropping the reel, and a discharge path for discharging the reel that has fallen from the drop end. And a stopper that prevents the reel from falling from the falling end by abutting against the carrier tape of the outermost layer wound around the reel located in the reel passage, and the stopper is the reel. When the remaining amount of the carrier tape wound around the reel in the passage falls below a certain level, the reel is arranged at a position that allows the reel to fall from the falling end.

In the component mounting device of the present invention, a component supply unit that draws in a carrier tape wound around a reel core and supplies the components stored in the carrier tape, and a component supply unit that supplies the components supplied by the component supply unit are taken out and a substrate. The reel support device includes a component mounting portion to be mounted on the reel and a reel support device attached to the component supply unit, and the reel support device has a support portion for supporting the outer peripheral edge of the reel in a vertical position and supports the reel support device. A reel passage in which one end of a portion is a falling end for dropping the reel, a discharge path for discharging the reel dropped from the falling end, and an outermost layer wound around the reel located in the reel passage. The stopper is provided with a stopper that prevents the reel from falling from the falling end by coming into contact with the carrier tape of the above, and the stopper has a remaining amount of the carrier tape wound around the reel in the reel passage of a certain amount or less. Then, the reel is arranged at a position that allows the reel to fall from the falling end.

According to the present invention, an empty reel can be automatically ejected without causing damage or deformation to the parts housed in the carrier tape.

The tape feeder 14 is detachably attached to the upper part of the feeder carriage 13. In the present embodiment, a plurality of tape feeders 14 are attached to the feeder carriage 13 side by side in the X-axis direction (FIG. 2).

In FIG. 1, the reel support device 15 is attached to the tape feeder 14, and is attached to the feeder carriage 13. Each reel support device 15 supports a plurality of reels 23. A carrier tape 24 containing the component BH is wound around the winding core 23M (FIG. 3) at the center of the reel 23.

As shown in FIG. 3, a slit 23S is provided in the winding core 23M of the reel 23, and the carrier tape 24 is wound around the winding core 23M with its end portion inserted into the slit 23S. When the reel 23 completely extends the carrier tape 24, the carrier tape 24 is separated from the reel 23 by the end portion thereof coming off (extracting) from the slit 23S of the reel 23.

In FIGS. 3 and 4 (enlarged view of the region AR in FIG. 3), the carrier tape 24 has a base tape 31 and a cover tape 32. The base tape 31 is provided with a large number of component storage portions 33 having a shape of opening upward in a row and at equal intervals in the longitudinal direction of the base tape 31. The component BH is stored in each of the plurality of component storage sections 33, and the cover tape 32 is attached to the base tape 31 so as to cover each component storage section 33. The base tape 31 is provided with a plurality of engaging holes 34 in a row and at equal intervals so as to line up in parallel with the row of the component storage portions 33.

The tape feeder 14 in this embodiment is an autoload type. The tape feeder 14 automatically pulls in and conveys the carrier tape 24 having the front end inserted into the tape insertion port 14G (FIG. 1) formed at the rear end portion, and conveys the carrier tape 24, and the component take-out position 14K on the front end portion side of the tape feeder 14. The component BH is supplied to (FIGS. 1 and 2).

When the tape feeder 14 finishes feeding the end portion of the carrier tape 24 being conveyed, the carrier tape 24 ends being conveyed, but the carrier tape 24 (preceding carrier tape 24) is subjected to the component feeding operation. While the replenishment carrier tape 24 (subsequent carrier tape 24) can be inserted into the tape insertion port 14G. When the end portion detection sensor 14S (FIG. 1) detects that the end portion of the preceding carrier tape 24 has passed a predetermined position inside the tape feeder 14, the tape feeder 14 pulls in the subsequent carrier tape 24. It will start and continue to supply parts BH.

In FIG. 1, the mounting head 16 includes a plurality of nozzles 16N extending downward. Each nozzle 16N can move up and down and rotate around the Z axis with respect to the mounting head 16, and a vacuum suction force for sucking the component BH can be generated at the lower end of each nozzle 16N. The head moving mechanism 17 moves the mounting head 16 in the horizontal plane.

In FIG. 1, the control device CTR (FIG. 1) included in the component mounting device 1 controls the operations of the substrate transport unit 12, each tape feeder 14, the mounting head 16, and the head moving mechanism 17. Further, the control device CTR includes a connector on the feeder carriage 13 side (connector CND on the carriage side) and a connector on the base 11 side (connector CNK on the substrate side) which are connected by connecting the feeder carriage 13 to the base 11. It is connected to the relay board CKB included in the feeder carriage 13 through the control device CTR, and the control device CTR controls each tape feeder 14 via the relay board CKB. The relay board CKB is a board having a function of individually switching a plurality of tape feeders 14 attached to the feeder carriage 13 and connecting them to the control device CTR. The terminating portion detection sensor 14S included in each tape feeder 14 is input to the control device CTR via the relay board CKB, the trolley side connector CND and the base side connector CNK, and the control device CTR is the detection information from the terminating portion detection sensor 14S. Based on the above, control is performed to start drawing in the subsequent carrier tape 24.

When the component BH is mounted on the board KB by the component mounting device 1, the board transport unit 12 first carries in and positions the board KB sent from the upstream process side. After positioning the board KB, each tape feeder 14 supplies the component BH to the component take-out position 14K, and the mounting head 16 picks up the component BH supplied by each tape feeder 14 by the nozzle 16N and places the component BH at a predetermined position on the substrate KB. Is installed. As described above, in the present embodiment, the mounting head 16 is a component mounting portion for taking out the component BH supplied by the tape feeder 14 which is a component supply unit and mounting the component BH on the board KB. When the mounting head 16 mounts all the component BHs to be mounted on the board KB, the board transport unit 12 operates to carry the board KB out of the component mounting device 1.

In the component mounting device 1 having such a configuration, the configuration of the reel support device 15 is characteristic in the present embodiment, and the description thereof will be described below. In FIGS. 2, 5 and 6, in the present embodiment, the first tape feeder 14A and the second tape feeder 14B are used as the tape feeder 14, and the feeder carriage 13 has eight first tape feeders. A tape feeder 14A and two second tape feeders 14B are attached. Here, the first tape feeder 14A is a tape feeder 14 that pulls in a carrier tape 24 having a small width for supplying a small-sized component BH and supplies the component BH. Further, the second tape feeder 14B is a tape feeder 14 that pulls in a carrier tape 24 having a large width for supplying a large-sized component BH and supplies the component BH.

In the present embodiment, as the reel support device 15, the first reel support device 15A (FIG. 4) attached to the first tape feeder 14A and the second reel support attached to the second tape feeder 14B Two types of devices 15B (FIG. 5) are used, and four first reel support devices 15A and two second reel support devices 15B are attached to the feeder carriage 13. In this embodiment, as shown in FIG. 2, one first reel support device 15A is arranged corresponding to two adjacent first tape feeders 14A. Further, one second reel support device 15B is arranged corresponding to one second tape feeder 14B.

First, the first reel support device 15A will be described. As shown in FIGS. 2, 5 and 7 (a), the first reel support device 15A is formed by a pair of left and right side plates 41 and a support portion 42 sandwiched between the pair of left and right side plates 41. It has one reel passage 43. The two reel passages 43 are composed of a reel passage 43 on the upper stage side (front side) (indicated by reference numeral 43J in FIG. 5) and a reel passage 43 on the lower stage side (rear side) (indicated by reference numeral 43G in FIG. 5). The support portion 42 of each reel passage 43 supports the outer peripheral edge of the reel 23 in the vertical posture, and one end thereof (the right end in FIGS. 5 and 7A) causes the reel 23 on the support portion 42 to drop. The drop end is 42T.

In the present embodiment, of the two first tape feeders 14A corresponding to the one first reel support device 15A, the first tape feeder 14A on one side (the side located on the right side of FIG. 2) is retracted. The reel 23 on which the carrier tape 24 is wound is supported in the reel passage 43 on the upper stage side. Further, the reel 23 on which the carrier tape 24 drawn by the first tape feeder 14A on the other side (the side located on the left side in FIG. 2) is wound is supported by the reel passage 43 on the lower stage side. As can be seen from FIG. 2, the width direction dimension (X-axis direction dimension) of one first reel support device 15A and the two first tape feeders 14A corresponding to the first reel support device 15A are combined. The dimensions are almost the same as the dimensions in the X-axis direction. Therefore, the reel 23 having a width direction dimension larger than the width direction dimension of the first tape feeder 14A can be supported by the first reel support device 15A.

In FIG. 7A, each reel passage 43 is wound with a first passage 43A that supports a reel 23 (referred to as a current reel 23C) around which the preceding carrier tape 24 is wound, and a subsequent carrier tape 24. It is provided with a second passage 43B that supports a reel 23 (referred to as a standby reel 23T). The first passage 43A is closer to the falling end 42T than the second passage 43B, so that each reel passage 43 supports the current reel 23C and the standby reel 23T in the order closer to the falling end 42T. ..

As shown in FIG. 5, a tape support roller 46 is provided above the first passage 43A of each reel passage 43. The carrier tape 24 drawn from the current reel 23C on the first passage 43A is drawn into the tape feeder 14 via the tape support roller 46. The tape support roller 46 prevents the carrier tape 24 drawn from the current reel 23C from interfering with other equipment.

In FIGS. 5 and 7A, a movement restricting portion 45 is provided between the first passage 43A and the second passage 43B in each reel passage 43. The movement limiting unit 45 has a function of restricting the standby reel 23T from moving to the first passage 43A. The movement limiting portion 45 is a protruding portion having a shape protruding upward here, but the shape of the movement limiting portion 45 is not limited to this.

In FIG. 7A, the reel 23 in the reel passage 43 is attached in a direction of rotating toward the drop end 42T due to the tension T when the wound carrier tape 24 is pulled into the first tape feeder 14A. Receive power R. The support portion 42 constituting the reel passage 43 supports the reel 23 in a state of being movable to the drop end 42T by rotation by the carrier tape 24 pulled by the tape feeder 14.

In the present embodiment, the first tape feeder 14A is an autoload type, and the subsequent carrier tape 24 is pulled in after the end portion of the preceding carrier tape 24 is pulled in. Therefore, FIG. 7A is shown. As shown in the above, even when the carrier tape 24 of the standby reel 23T is inserted into the tape insertion port 14G of the first tape feeder 14A, the first tape feeder 14A is the carrier tape 24 of the current reel 23C. The carrier tape 24 of the standby reel 23T is not pulled in while it is being pulled in. Therefore, in this state, no tension acts on the carrier tape 24 of the standby reel 23T, and no urging force in the direction of rotation toward the falling end 42T acts on the standby reel 23T.

In FIGS. 5 and 7A, stoppers 50 are provided at positions separated from the falling end 42T of the upper reel passage 43 and at positions separated from the falling end 42T of the lower reel passage 43, respectively. ing. The stopper 50 (upper stopper 50) provided corresponding to the reel passage 43 on the upper stage side and the stopper 50 (stopper 50 on the lower stage side) provided corresponding to the reel passage 43 on the lower stage side correspond to each other. By contacting the outermost layer carrier tape 24 wound around the current reel 23C located in the reel passage 43 on the side, the current reel 23C is prevented from falling from the drop end 42T. The stopper 50 does not damage the carrier tape 24 and the component BH in the component storage portion 33 due to friction with the carrier tape 24, and the reel 23 is smoothly rotated on the support portion 42. As such, it is preferable that the roller rolls while contacting the carrier tape 24.

Each stopper 50 is arranged at a position that allows the current reel 23C to fall from the drop end 42T when the remaining amount of the carrier tape 24 wound around the current reel 23C in the corresponding reel passage 43 falls below a certain level. ing. Specifically, as shown in FIG. 7B, the stopper 50 is located at a position separated from the reel passage 43 or the drop end 42T by a distance larger than the sum of the radius r1 of the reel 23 and the radius r2 of the winding core 23M. Is located in. Therefore, the current reel 23C in which the end portion of the carrier tape 24 wound around the winding core 23M is separated from the slit 23S will surely fall from the drop end 42T.

As described above, the carrier tape 24 wound around the current reel 23C receives an urging force R in a direction of rotating toward the drop end 42T due to the tension T when it is drawn into the tape feeder 14. Therefore, in the current reel 23C, the remaining amount of the carrier tape 24 is reduced to a certain level or less, that is, the winding diameter of the carrier tape 24 is reduced to a size that allows the carrier tape 24 to pass between the reel passage 43 (falling end 42T) and the stopper 50, or is wound. When the end portion of the carrier tape 24 comes off from the core 23M, it automatically falls from the drop end 42T of the reel passage 43 (FIG. 7 (b) → FIG. 8 (a)).

After the current reel 23C has fallen from the drop end 42T, when the end portion of the carrier tape 24 that has come off the slit 23S of the dropped current reel 23C is detected by the end portion detection sensor 14S of the first tape feeder 14A, this The carrier tape 24 wound around the standby reel 23T is pulled in by the first tape feeder 14A. When the carrier tape 24 of the standby reel 23T is pulled into the first tape feeder 14A, the tension T acting on the carrier tape 24 causes the standby reel 23T to have an urging force R in the direction of rotation toward the drop end 42T. It works. Therefore, the standby reel 23T gets over the movement restriction unit 45 and moves to the first passage 43A (FIG. 8B). As described above, in the present embodiment, the movement limiting unit 45 allows the standby reel 23T rotated by the carrier tape 24 drawn by the tape feeder 14 to get over and move to the first passage 43A. ..

In FIG. 5, a discharge path 44 is provided below the two reel passages 43 to roll and discharge the reel 23 (referred to as the discharge reel 23H) that has fallen from the drop end 42T of each of the two reel passages 43. There is. On the outlet side of the discharge path 44, a discharge reel accommodating portion 47 for accommodating the discharge reel 23H that has rolled and moved to the outlet side is provided.

The current reel 23C supported by the first passage 43A falls from the falling end 42T, and the standby reel 23T previously supported by the second passage 43B moves to the first passage 43A and becomes the current reel 23C. When this happens, the worker OP installs a new standby reel 23T in the vacant second passage 43B (arrow S shown in FIG. 9A). Then, the carrier tape 24 is pulled out from the new standby reel 23T, and the leading portion thereof is inserted into the tape insertion port 14G of the first tape feeder 14A (arrow E shown in FIG. 9B). As a result, the state returned to the state shown in FIG. 7A is restored, and the reel 23 replacement work is completed.

Next, the second reel support device 15B will be described. As shown in FIGS. 2, 6 and 10 (a), the second reel support device 15B is formed by a pair of left and right side plates 141 and a support portion 142 located between the pair of left and right side plates 141. It has a reel passage 143 to be made. The support portion 142 of the reel passage 143 supports the outer peripheral edge of the reel 23 in the vertical posture, and one end thereof (the right end in FIGS. 6 and 10A) drops the reel 23 on the support portion 142. It is the end 142T.

In FIG. 10A, the reel passage 143 supports a first passage 143A that supports the current reel 23C around which the preceding carrier tape 24 is wound, and a standby reel 23T around which the succeeding carrier tape 24 is wound. It is provided with two passages 143B. The first passage 143A is closer to the falling end than the second passage 143B, so that the reel passage 143 supports the current reel 23C and the standby reel 23T in the order closer to the falling end 142T.

In FIGS. 6 and 10A, a movement limiting portion 145 is provided between the first passage 143A and the second passage 143B in the reel passage 143. The movement limiting unit 145 has a function of restricting the standby reel 23T from moving to the first passage 143A. The movement limiting portion 145 is a protruding portion having a shape protruding upward here, but the shape of the movement limiting portion 145 is not limited to this, as in the case of the first reel support device 15A. ..

In FIG. 10A, the reel 23 in the reel passage 143 is attached in a direction of rotating toward the drop end 142T due to the tension T when the wound carrier tape 24 is pulled into the second tape feeder 14B. Receive power R. The support portion 142 constituting the reel passage 143 supports the reel 23 in a state of being movable to the drop end 142T by rotation by the carrier tape 24 pulled by the tape feeder 14.

In the present embodiment, the second tape feeder 14B is an autoload type, and the trailing carrier tape 24 is pulled in after the end portion of the preceding carrier tape 24 is pulled in. Therefore, FIG. 10A shows. As shown in the above, even when the carrier tape 24 of the standby reel 23T is inserted into the tape insertion port 14G of the second tape feeder 14B, the second tape feeder 14B is the carrier tape 24 of the current reel 23C. The carrier tape 24 of the standby reel 23T is not pulled in while it is being pulled in. Therefore, in this state, no tension acts on the carrier tape 24 of the standby reel 23T, and no urging force in the direction of rotation toward the falling end 42T acts on the standby reel 23T.

In FIGS. 6 and 10A, a stopper 150 is provided at a position away from the falling end 142T of the reel passage 143. The stopper 150 abuts on the outermost carrier tape 24 wound around the current reel 23C located in the reel passage 143 to prevent the current reel 23C from falling from the drop end 142T. The stopper 150 prevents the carrier tape 24 and the component BH in the component accommodating portion 33 from being damaged by friction with the carrier tape 24, and the reel 23 is smoothly rotated on the support portion 142. As such, it is preferable that the roller rolls while contacting the carrier tape 24.

The stopper 150 is arranged at a position that allows the current reel 23C to fall from the drop end 142T when the remaining amount of the carrier tape 24 wound around the current reel 23C in the reel passage 143 falls below a certain level. Specifically, as shown in FIG. 10B, the stopper 150 has a fall direction of the reel 23 with respect to the fall end 142T by a distance larger than the sum of the radius r1 of the reel 23 and the radius r2 of the winding core 23M. In FIG. 5, they are arranged at positions separated from each other (to the right). Therefore, the current reel 23C in which the end portion of the carrier tape 24 wound around the winding core 23M is separated from the slit 23S will fall from at least the drop end 42T.

In the case of the second reel support device 15B as well, as in the case of the first reel support device 15A, the carrier tape 24 wound around the current reel 23C has a drop end due to the tension T when it is pulled into the tape feeder 14. It receives an urging force R in the direction of rotation toward 142T. Therefore, when the remaining amount of the carrier tape 24 becomes equal to or less than a certain level, the current reel 23C automatically drops from the drop end 42T of the reel passage 43 (FIGS. 10 (b) → 11 (a)).

After the current reel 23C has fallen from the drop end 142T, when the end portion of the carrier tape 24 that has come off the slit 23S of the dropped current reel 23C is detected by the end portion detection sensor 14S of the second tape feeder 14B, this Is used as a trigger, the carrier tape 24 wound around the standby reel 23T is drawn into the second tape feeder 14B. When the carrier tape 24 of the standby reel 23T is pulled into the second tape feeder 14B, the tension T acting on the carrier tape 24 causes the standby reel 23T to have an urging force R in the direction of rotation toward the drop end 42T. It works. Therefore, the standby reel 23T gets over the movement restriction unit 145 and moves to the first passage 143A (FIG. 11B). As described above, in the present embodiment, the movement limiting unit 145 allows the standby reel 23T rotated by the carrier tape 24 drawn by the tape feeder 14 to get over and move to the first passage 143A. ..

In FIG. 6, below the reel passage 143, a discharge passage 144 is provided to roll and discharge the discharge reel 23H that has fallen from the drop end 142T of the reel passage 143. A discharge control bar 148 that regulates the discharge of the discharge reel 23H is provided on the side plate 141 corresponding to the outlet side end of the discharge path 144. The discharge control bar 148 is a rod-shaped member extending in the horizontal direction, and by moving the member with respect to the side plate 141, it is possible to take out the discharge reel 23H whose discharge is regulated by the discharge control bar 148.
