  However, it has been difficult to appropriately estimate the amount of tape in the tape collection container based on the number of substrates produced and the number of times the tape is fed from the tape feeder as in Patent Documents 1 and 2. Therefore, the timing of notifying that the tape collected in the tape collection container needs to be discarded may not always be appropriate for the worker's work.

  The present invention has been made in view of the above problems, and has as its object to provide a technique capable of notifying the necessity of discarding a tape collected in a tape collection container at an appropriate timing for an operation of an operator. .

  The component mounter according to the present invention includes a tape transport unit that transports a tape capable of housing a plurality of components arranged side by side, and a component mount unit that removes the component transported to a predetermined position by the tape transport unit from the tape and mounts the component on a board. , A tape discharge unit that cuts and discharges the tape after parts have been taken out of the tape transport unit, a tape collection container that collects the tape discharged from the tape discharge unit, and a tape collection container An input operation unit for receiving an input by a worker of a timing at which the tape to be discarded is to be discarded, and a timing for executing a discard notification to notify the worker that the tape collected in the tape collection container needs to be discarded. A notification timing determination unit that is determined according to the scheduled timing input to the operation unit, and a discard notification at a timing determined by the notification timing determination unit. And a notification unit that performs.

  The tape discard timing notifying method according to the present invention includes a step of cutting a tape after a component is taken out and discharging the tape from a tape discharge unit while conveying a tape capable of housing a plurality of components in a line, and It is necessary to collect the ejected tape in the tape collection container, receive the operator's input of the scheduled timing to dispose of the tape collected in the tape collection container, and dispose of the tape collected in the tape collection container. And a step of determining the timing of executing the discard notification that informs the worker that this is the case according to the scheduled timing, and the step of executing the discard notification at the timing determined according to the scheduled timing.

  In the present invention configured as described above (the component mounter, the tape discarding timing notifying method), the operator can input the scheduled timing for discarding the tape collected in the tape collecting container. Then, the timing at which the discard notification for notifying the necessity of discarding the tape is executed is determined according to the scheduled timing input by the operator. As a result, it is possible to notify, at an appropriate timing for the worker's work, the necessity of discarding the tape collected in the tape collection container.

  At this time, the notification timing determination unit may be configured to configure the component mounter so as to determine to execute the discard notification at the scheduled timing input to the input operation unit. With such a configuration, the operator can reliably discard the tape at the timing that he has planned.

  The notification timing determination unit determines that the discard notification is to be performed at the scheduled timing input to the input operation unit when the operation status of the tape transport unit satisfies a predetermined condition, and when the operation status does not satisfy the predetermined condition. Alternatively, the component mounter may be configured to determine that the discard notification is to be executed at a timing calculated according to the operation status. With such a configuration, when the operation state of the tape transport unit satisfies the predetermined condition, the operator can reliably discard the tape at the timing that he has planned. On the other hand, when the operation status of the tape transport unit does not satisfy the predetermined condition, it is determined to execute the discard notification at the timing calculated according to the operation status. Therefore, it is possible to notify the necessity of discarding the tape at an appropriate timing according to the operation state of the tape transport unit.

  Further, when the operation status does not satisfy the predetermined condition, the notification timing determination unit performs the discard notification at the timing calculated based on the tape occupied volume estimated from the operation status of the volume occupied by the tape collected in the tape collection container. The component mounter may be configured so as to be determined. With such a configuration, it is possible to notify the necessity of discarding the tape at an appropriate timing according to the tape occupied volume of the tape in the tape collection container which increases according to the operation state of the tape transport unit.

  The tape collection container collects the tape transported by the plurality of tape transport units and cut by the tape discharge unit, and the notification timing determination unit divides the plurality of tape transport units into a plurality of groups and belongs to the group. The component mounter may be configured to determine to execute the discard notification at the timing calculated based on the result of estimating the tape occupied volume of the tape transported by the tape transport unit for each group. In such a configuration, even when the operation status of each of the plurality of tape transport units varies, the necessity of discarding the tape is notified at an appropriate timing in accordance with the volume occupied by the tape in the tape collection container. It becomes possible.

  The notification timing determination unit is configured to determine at least one of a width of the tape transported by the tape transport unit, a length of the tape transported by the tape transport unit in one intermittent transport, and a number of times the tape is discharged by the tape discharge unit. The component mounter may be configured to estimate the tape occupied volume. As a result, the volume occupied by the tape in the tape container can be estimated with high accuracy.

  In addition, the notification timing determination unit configures the component mounter to determine that the discard notification is to be executed at a timing calculated according to the operation status of the tape transport unit when there is no input of the scheduled timing to the input operation unit. You may. With such a configuration, it is possible to appropriately cope with a case where the operator cannot judge the scheduled timing of discarding the tape collected in the tape collection container.

  As described above, according to the present invention, it is possible to notify the necessity of discarding the tape collected in the tape collection container at a timing appropriate for the operation of the worker.

It is a fragmentary sectional view showing typically the modification of control of execution timing of discard information.

  FIG. 1 is a partial plan view schematically showing a component mounter according to the present invention. In this figure and the following figures, XYZ orthogonal coordinates composed of a Z direction parallel to the vertical direction, an X direction and a Y direction parallel to the horizontal direction, respectively, are appropriately shown. The component mounter 1 includes a pair of conveyors 12 provided on a base 11. Then, the component mounter 1 mounts the components on the board S carried into the work position (the position of the board S in FIG. 1) from the upstream side in the X direction (board transport direction) by the conveyor 12, and completes the component mounting. The conveyed substrate S is carried out from the work position to the downstream side in the X direction by the conveyor 12.

  The component mounter 1 includes a pair of Y-axis rails 21 extending in the Y direction, a Y-axis ball screw 22 extending in the Y direction, and a Y-axis motor My for driving the Y-axis ball screw 22 to rotate. 23 is fixed to a nut of a Y-axis ball screw 22 in a state supported by a pair of Y-axis rails 21 and 21 so as to be movable in the Y direction. An X-axis ball screw 24 extending in the X direction and an X-axis motor Mx for rotating and driving the X-axis ball screw 24 are attached to the head support member 23, and the head unit 3 can move on the head support member 23 in the X direction. And is fixed to a nut of the X-axis ball screw 24 while being supported by the. Therefore, the head unit 3 can be moved in the Y direction by rotating the Y-axis ball screw 22 by the Y-axis motor My, or the head unit 3 can be moved in the X direction by rotating the X-axis ball screw 24 by the X-axis motor Mx. it can.

  On each side of the pair of conveyors 12 in the Y direction, two component supply units 25 are arranged in the X direction. A plurality of tape feeders 4 arranged in the X direction are detachably attached to each component supply unit 25. Each tape feeder 4 has a small piece-like component (chip) such as an integrated circuit, a transistor, and a capacitor. A reel R on which a tape TP containing electronic components) is stored at predetermined intervals is disposed. Then, the tape feeder 4 supplies the components in the tape TP to the component supply position 40 by intermittently sending the tape TP to the head unit 3 side.

  The head unit 3 has a plurality (four) of mounting heads 31 arranged in the X direction. Each mounting head 4 has a long shape extending in the Z direction (vertical direction), and can suck and hold components by a nozzle detachably attached to a lower end thereof. That is, the mounting head 31 moves above the tape feeder 4 and sucks the components supplied by the tape feeder 4. Subsequently, the mounting head 31 moves above the substrate S at the work position to release the suction of the component, thereby mounting the component on the substrate S.

  FIG. 2 is a side view schematically illustrating an example of the configuration of a feeder mounting trolley for collectively attaching and detaching a plurality of tape feeders to and from a component supply unit of a component mounter, and the periphery thereof. In the figure, the sign (+ Y) is given to the front side in the Y direction (front-back direction), and the sign (-Y) is given to the rear side in the Y direction. The feeder mounting cart 5 is detachably attached to each of the four component supply units 25. The feeder mounting cart 5 has a feeder mounting portion 51 in front (+ Y), and a plurality of tape feeders 4 arranged in the X direction are removably mounted to the feeder mounting portion 51. Further, the feeder mounting cart 5 has a reel holding portion 52 behind (-Y) the feeder mounting portion 51, and a plurality of reels R arranged in the X direction are held by the reel holding portion 52. In this way, a plurality of reels R are provided corresponding to the plurality of tape feeders 4, and each tape feeder 4 is loaded with the tape TP pulled out from the corresponding reel R.

  The tape TP is a conventionally known embossed tape, and has a configuration in which a cover tape CV is attached to the upper surface of a carrier tape CR. That is, the carrier tape CR accommodates components in each of a plurality of accommodation pockets (component accommodation portions) arranged at an equal pitch as an example, and the cover tape CV is attached to the upper surface of the carrier tape CR and the inside of the accommodation pockets. Cover the parts. In addition, a plurality of engagement holes arranged at regular intervals along the edge of one side of the carrier tape CR penetrate therethrough.

  The tape feeder 4 has a flat box-shaped feeder main body 41 and a tape guide 42 extending in the Y direction within the feeder main body 41, and a component supply opening upward in front (+ Y) of the feeder main body 41. Feed the part to location 40. The feeder main body 41 has a sprocket 43 provided close to the component supply position 40. The tape TP inserted into the tape guide 42 from the rear (-Y) end of the feeder main body 41 is replaced with a tape guide 42. Along to the sprocket 43. The sprocket 43 intermittently rotates while engaging with the engagement hole of the tape TP, thereby intermittently conveying the tape TP forward (+ Y). As a result, the components in the storage pocket of the carrier tape CR are intermittently supplied to the component supply position 40, and the mounting head 31 takes out the component supplied to the component supply position 40 from the storage pocket.

  Further, a cover peeling section 44 is provided on the tape guide 42 halfway to the component supply position 40, and the cover peeling section 44 peels the cover tape CV from the carrier tape CR. Then, the peeled cover tape CV is accommodated in the cover accommodating portion 45 provided behind (-Y) the feeder main body 41. Thus, the carrier tape CR of the tape TP from which the cover tape CV has been peeled is guided to the component supply position 40. Then, the carrier tape CR from which the components have been taken out at the component supply position 40 is discharged from the front (+ Y) end of the tape guide 42 to the outside of the feeder main body 41, and is further fed out by the sprocket 43 to be fed out by the tape collection mechanism 53. Transported to

  That is, the feeder mounting cart 5 has the tape collecting mechanism 53 below the feeder mounting portion 51. The tape collecting mechanism 53 has a tape discharging section 6 for cutting and discharging the carrier tape CR conveyed by the sprocket 43, and a tape collecting container 7 arranged on the bottom plate 54 of the feeder mounting cart 5. A guide mechanism for guiding the carrier tape CR from the sprocket 43 of the tape feeder 4 to the tape collecting mechanism 53 can be appropriately provided, but this guide mechanism is omitted in FIG.

  The tape discharge unit 6 has an exterior member 61 attached to the main body frame of the component mounting machine 1, and cuts the carrier tape CR loaded from the entrance 611 opening at the top of the exterior member 61. The liquid is discharged from a discharge port 612 opened at the bottom. The tape discharge unit 6 includes a cutter 62, a receiving member 63 that receives the cutter 62, and an air cylinder 64 that drives the cutter 62 in the Y direction. The cutter 62 and the receiving member 63 are arranged opposite to each other in the Y direction below the carry-in port 611, and the carrier tape CR entered from the carry-in port 611 is transported between the cutter 62 and the receiving member 63. The air cylinder 64 reciprocates the cutter 62 in the Y direction between a cutting position where the tip of the cutter 62 contacts the receiving member 63 and a retracted position where the tip of the cutter 62 separates from the receiving member 63. Therefore, when the cutter 62 is in the retracted position, the carrier tape CR that enters from the carry-in port 611 due to the intermittent conveyance by the sprocket 43 passes between the cutter 62 and the receiving member 63 and is lower than the cutter 62. Hanging down. Subsequently, when the cutter 62 moves to the cutting position, the carrier tape CR sandwiched between the tip of the cutter 62 and the receiving member 63 is cut, and the carrier tape CR on the lower end side from the cut portion by the cutter 62 falls. Are discharged from the discharge port 612.

  A tape collection container 7 is provided below the tape discharge unit 6. The carrier tape CR discharged from the discharge port 612 of the tape discharge unit 6 drops from the discharge port 612 and is collected in the tape collection container 7. You. The tape collection container 7 is a box having an opening 72 facing upward at a rectangular parallelepiped upper end provided with a hollow interior 70. In a state where the tape collection container 7 is placed on the bottom plate 54 of the feeder mounting cart 5, the bottom surface 701 of the hollow interior 70 is held horizontally. A stopper 55 is provided on the bottom plate 54 of the feeder mounting cart 5. When the tape collection container 7 inserted into the feeder mounting cart 5 along the bottom plate 54 from the rear (-Y) side comes into contact with the stopper 55. The opening 72 of the tape collection container 7 is positioned immediately below the discharge port 612 of the tape discharge section 6. Therefore, the carrier tape CR discharged from the discharge port 612 falls into the hollow interior 70 through the opening 72 of the tape collection container 7 and is collected in the hollow interior 70 of the tape collection container 7.

  FIG. 3 is a block diagram partially showing an example of an electrical configuration provided in the component mounter of FIG. The component mounter 1 includes a control unit 90, which is a computer including a CPU (Central Processing Unit) and a RAM (Random Access Memory), and a storage unit 91, including a HDD (Hard Disk Drive). The control unit 90 performs overall control of the component mounter 1, and the storage unit 91 stores various data such as board data Ds that defines a procedure for component mounting. Then, the control unit 90 controls each unit of the component mounter 1 based on the board data Ds, and executes component mounting according to the procedure specified by the board data Ds.

  The control unit 90 can communicate with each of the tape feeders 4 attached to the feeder attachment unit 51 of the feeder attachment cart 5. The control unit 90 controls the air cylinder 64 to cut the carrier tape CR by the cutter 62 at a frequency corresponding to the operation of the tape feeder 4. Specifically, the control unit 90 counts the number of intermittent transports of the tape TP performed by the sprockets 43 of each of the plurality of tape feeders 4. The carrier tape CR conveyed from the tape feeder 4 of FIG.

The storage unit 91 stores an occupied volume estimation table Te used for estimating the tape occupied volume V occupied in the tape collection container 7 by the carrier tape CR collected in the tape collection container 7. The occupied volume estimation table Te includes the following parameters: the number of feeds Pn: the number of times the sprocket 43 of the tape feeder 4 intermittently conveys the tape TP; Distance / tape width Pw: width of carrier tape CR conveyed by tape feeder 4 / cut frequency Pf: frequency of cutting carrier tape CR (number of times per predetermined time)
, An estimated value of the tape occupied volume V is given. That is, it is considered that the volume occupied by the carrier tape CR in the tape collection container 7 basically increases according to the value of Pn × Pp × Pw. However, if the frequency of cutting the carrier tape CR is high, the cut carrier tape CR is short, and each carrier tape CR can be stored in the tape collection container 7 while suppressing the gap. Therefore, the occupied volume of the carrier tape CR is reduced. On the other hand, if the frequency of cutting the carrier tape CR is low, the cut carrier tape CR becomes longer, and each carrier tape CR is accommodated in the tape collection container 7 with a corresponding gap generated between them. Therefore, the occupied volume of these carrier tapes CR becomes large. Therefore, the tape occupation volume V is given by the following equation:
V = K (Pf) × Pn × Pp × Pw Equation 1
Is estimated based on Here, the coefficient K (Pf) is a coefficient whose value decreases stepwise or continuously as the cut frequency Pf increases, and is obtained experimentally in advance.

  Further, the component mounter 1 is configured with input devices such as a keyboard and a mouse and receives an input operation by an operator, and is configured with a liquid crystal display and the like to display a state of the component mounter 1 to the operator. And a unit 93. In addition, although the case where the input operation unit 92 and the display unit 93 are configured separately is shown here, the input operation unit 92 and the display unit 93 may be integrally configured by, for example, a touch panel display or the like. In particular, by performing an input operation on the input operation unit 92, the operator can input the scheduled timing Ts for discarding the carrier tape CR collected in the tape collection container 7 to the input operation unit 92. Reference numeral 90 stores the scheduled timing Ts input to the input operation unit 92 in the storage unit 91. In this way, the operator can input the scheduled timing Ts based on the results such as the frequency of discarding the carrier tape CR performed in past component mounting, for example.

  Further, the component mounter 1 includes a notification unit 94 that performs a discard notification that notifies a worker that the carrier tape CR collected in the tape collection container 7 needs to be discarded by voice, light, or a combination thereof. Prepare. Then, in the present embodiment, the control unit 90 controls the execution timing of the discard notification by the notification unit 94.

  FIG. 4 is a flowchart illustrating an example of control of the execution timing of the discard notification. The flowchart of FIG. 4 is executed by the control unit 90 controlling each unit of the component mounter 1. In step S101, the control unit 90 monitors whether the scheduled timing Ts for disposing of the carrier tape CR collected in the tape collection container 7 has been input to the input operation unit 92 by the operator. Then, when there is an input of the scheduled timing Ts to the input operation unit 92 (“YES” in step S101), the control unit 90 stores the scheduled timing Ts in the storage unit 91 (step S102).

  Subsequently, when component mounting is started by the component mounter 1 (“YES” in step S103), the control unit 90 starts counting the number of times the carrier tape CR is cut by the cutter 62 (step S104). It is monitored whether the CR cut execution pace is appropriate (step S105). That is, the component mounting in the component mounter 1 is executed according to the mounting procedure specified in the board data Ds. Therefore, the sprocket 43 of each tape feeder 4 intermittently sends out the tape TP according to the substrate data Ds, and supplies the components in the tape TP to the component supply position 40. On the other hand, as described above, the cutting of the carrier tape CR is executed when the intermittent conveyance of any of the tape feeders 4 exceeds a predetermined number. In such control, the number of cuts of the carrier tape CR increases at a pace corresponding to the progress of component mounting based on the board data Ds. Therefore, if the progress of the component mounting is smooth, the execution pace of the cut of the carrier tape CR becomes equal to or more than a predetermined frequency (appropriate), and the carrier tape CR in the tape collection container 7 also increases at a corresponding pace. On the other hand, if the progress of component mounting is delayed, the execution pace of cutting the carrier tape CR becomes less than the predetermined frequency, and the increasing pace of the carrier tape CR in the tape collection container 7 decreases. Therefore, the control unit 90 confirms whether or not the amount of the carrier tape CR cut by the cutter 62 and collected in the tape collection container 7 is increasing at an appropriate pace by executing step S105.

  If it is determined in step S105 that the execution pace of the cutting of the carrier tape CR is appropriate (greater than or equal to a predetermined frequency) ("YES" in step S105), the control unit 90 proceeds to step S106 and reaches the scheduled timing Ts. It is determined whether or not it has been done. If the scheduled timing Ts has not been reached ("NO" in step S106), the control unit 90 returns to step S105 and repeats steps S105 and S106. Then, the amount of the carrier tape CR in the tape collection container 7 continues to increase at an appropriate pace in accordance with the smooth progress of the component mounting (“YES” in Step S105), and reaches the scheduled timing Ts (Step S106). “YES”), the control unit 90 causes the notification unit 94 to execute the discard notification (step S107).

  On the other hand, if it is determined in step S105 that the execution pace of the cut of the carrier tape CR is not appropriate (less than the predetermined frequency) (“NO” in step S105), the control unit 90 proceeds to step S108, and proceeds to step S108. The CR starts to estimate the occupied volume of the tape collection container 7. That is, the fact that the execution pace of the cut of the carrier tape CR is not appropriate indicates that the pace of increase in the amount of the carrier tape CR collected in the tape collection container 7 is low. Therefore, at the scheduled timing Ts input by the operator based on his / her experience and experience, the volume occupied by the carrier tape CR in the tape collection container 7 is not so large, and it is expected that the tape TP need not be discarded. You. Therefore, the control unit 90 executes step S108.

  In step S108, the tape occupation volume V is calculated based on the above equation 1 based on the number of feeds Pn, the feed pitch Pp, the tape width Pw, and the cut frequency Pf which have been performed since the last time the notification unit 94 performed the discard notification. Is estimated. Subsequently, in step S109, it is checked whether or not the tape occupied volume V is equal to or larger than a threshold. If the tape occupied volume V is smaller than the threshold ("NO" in step S109), the control unit 90 returns to step S108 and repeats steps S108 and S109. Then, when the tape occupied volume V becomes equal to or larger than the threshold value ("YES" in step S109), the control unit 90 causes the notification unit 94 to execute the discard notification (step S107).

  If the component mounting is started (“YES” in step S110) while the input of the scheduled timing Ts cannot be confirmed in step S101 (“NO” in step S101), the step is performed in the same manner as described above. Steps S108, S109, and S107 are performed.

  In the embodiment configured as described above, the operator can input the scheduled timing Ts at which the carrier tape CR collected in the tape collection container 7 is to be discarded. Then, the timing of executing the discard notification for notifying that the carrier tape CR needs to be discarded is determined according to the scheduled timing Ts input by the operator. As a result, it is possible to notify the user of the need to discard the tape collected in the tape collection container 7 at a timing appropriate for the worker's work.

  Further, since it is possible to notify the necessity of discarding the tape collected in the tape collection container 7 at an appropriate timing, it is possible to reduce the frequency with which the operator discards the carrier tape CR from the tape collection container 7. And the burden on the operator can be reduced. Further, even if the operator cannot discard the carrier tape CR at an appropriate frequency, the amount of the carrier tape CR overflowing from the tape collection container 7 can be suppressed. Therefore, when the tape collection container 7 is set after discarding the carrier tape CR, occurrence of a defect that the tape collection container 7 cannot be correctly set at a predetermined position due to the carrier tape CR overflowing from the carrier tape CR can be suppressed. Alternatively, the labor required for cleaning the overflowing carrier tape CR can be reduced.

  At this time, the control unit 90 monitors whether the execution pace of the cutting of the carrier tape CR by the cutter 62 is appropriate (step S105). The execution pace of the cut of the carrier tape CR has a correlation with the number of times the carrier tape CR is fed by the tape feeder 4, and indicates the operation state of the tape feeder 4. When the operation state of the tape feeder 4 satisfies the predetermined condition (that is, when the cut execution pace until the scheduled timing Ts is reached is equal to or longer than the predetermined pace), the control unit 90 notifies the discard at the scheduled timing Ts. Is determined to be executed (steps S105 and S106). On the other hand, when the operation status of the tape feeder 4 does not satisfy the predetermined condition (that is, when the cut execution pace until the scheduled timing Ts is reached is less than the predetermined pace), the control unit 90 sets the operation of the tape feeder 4 to an operation. It is determined to execute the discard notification at the timing calculated according to the situation (steps S108 and S109). With such a configuration, when the operation state of the tape feeder 4 satisfies the predetermined condition, the operator can reliably discard the carrier tape CR at the timing that he has planned. On the other hand, when the operation status of the tape feeder 4 does not satisfy the predetermined condition, the necessity of discarding the carrier tape CR can be notified at an appropriate timing according to the operation status.

  When the operation state of the tape feeder 4 does not satisfy the predetermined condition, the control unit 90 calculates the volume occupied by the carrier tape CR collected in the tape collection container 7 based on the tape occupied volume V estimated from the operation state. It is determined that the discard notification is to be executed at the specified timing. With such a configuration, it is possible to notify the necessity of discarding the carrier tape CR at an appropriate timing according to the tape occupied volume V in the tape collection container 7 which increases according to the operation state of the tape feeder 4.

  In particular, by calculating the tape occupied volume V based on the feed pitch Pp, the tape width Pw, and the cut frequency Pf as well as the number of feeds Pn, the tape occupied volume V can be estimated with high accuracy. In the above example, all of these parameters Pp, Pw, and Pf were used for calculating the tape occupied volume V. However, by calculating using at least one of these, the tape occupied volume V can be estimated with higher precision than when calculating based on only the number of times of feeding Pn.

  When there is no input of the scheduled timing Ts to the input operation unit 92 (in the case of “NO” in step S101), the control unit 90 executes the discard notification at the timing calculated according to the operation state of the tape feeder 4. Then, it is determined (steps S108 and S109). With such a configuration, it is possible to appropriately cope with the case where the operator cannot determine the scheduled timing Ts at which the carrier tape CR collected in the tape collection container 7 is to be discarded.

  As described above, in the present embodiment, the component mounter 1 corresponds to an example of the “component mounter” of the present invention, and the tape feeder 4 corresponds to an example of the “tape transport unit” of the present invention. Reference numeral 31 corresponds to an example of the “component mounting unit” of the present invention, the tape discharging unit 6 corresponds to an example of the “tape discharging unit” of the present invention, and the tape collecting container 7 is an example of the “tape collecting container” of the present invention. , The input operation unit 92 corresponds to an example of the “input operation unit” of the invention, the control unit 90 corresponds to an example of the “timing determination unit” of the invention, and the carrier tape CR corresponds to the “tape” of the invention. , And the scheduled timing Ts corresponds to an example of the “scheduled timing” of the present invention.

  The present invention is not limited to the above embodiment, and various changes can be made to the above described one without departing from the gist of the invention. For example, when the carrier tape CR discharged from each of the plurality of tape feeders 4 is collected in one tape collection container 7 as described above, if the operation status of each tape feeder 4 varies, the carrier tape CR is accumulated in the tape collection container 7. In some cases, the amount of the carrier tape CR varies depending on the position. Therefore, control as shown in FIG. 5 may be executed.

  FIG. 5 is a partial cross-sectional view schematically showing a modification of the control of the execution timing of the discard notification. In the modified example shown in the figure, the control unit 90 divides a plurality of tape feeders 4 into a plurality of groups G and performs control. Specifically, steps S108, S109, and S107 shown in the flowchart of FIG. 4 are executed as follows. That is, the control unit 90 estimates the tape occupied volume V occupied in the tape collection container 7 by the carrier tape CR transported by the tape feeders 4 belonging to the group G for each group G (step S108). If the tape occupied volume V of any one group G is equal to or larger than the threshold value Vt ("YES" in step S109), discard notification is performed at this timing (step S107). In such a configuration, even when the operation status of each of the plurality of tape collection containers 7 varies, the carrier tape CR can be appropriately controlled at an appropriate timing according to the tape occupied volume V of the carrier tape CR in the tape collection container 7. It is possible to notify the necessity of discarding.

  In the above-described embodiment, whether to determine the timing of discard notification based on the tape occupied volume V is determined based on the execution pace of cutting the carrier tape CR. However, such a determination can be made based on various other values (for example, the number of intermittent rotations of the sprocket 43) that correlate with the operation state of the tape feeder 4.

  Further, the configuration of the tape collection container 7 is not limited to the above example. Furthermore, the arrangement of the tape collection container 7 can be changed, and the tape collection container 7 may be arranged to be inclined from the front (+ Y) to the rear (-Y).

  Further, the cover tape CV was folded and housed in the cover housing part 45. However, even when both the cover tape CV and the carrier tape CR are cut by the cutter 62 and collected in the tape collection container 7 as in Japanese Patent Application Laid-Open No. Hei 7-226599, for example, It is possible to execute the discard notification at the timing.
