Demand for labor saving and labor saving is increasing in the industrial world including the electronic component mounting field, and it is required to promote the automation of the above-mentioned cover tape processing as much as possible. However, the prior arts shown in the above-mentioned patent document examples have the following problems in automation. That is, in the prior art shown in Patent Document 1, the cover tape peeled off and accommodated inside the tape accommodation box is in a state of being entangled by being randomly pushed in from one direction. For this reason, mechanical handling is difficult, and it is extremely difficult to target it for automation.

In the prior art shown in Patent Document 2, the peeled cover tape intersects with the carrier tape sent from the upstream side and is discharged downward. Therefore, each time a new carrier tape is set, it is used for mounting. It is inevitable that waste parts will be discarded without being discarded. In addition, since the crossed cover tapes need to guide the narrow gap between the adjacent tape feeders downward, automation is difficult.

The prior art shown in Patent Document 3 is suitable for automation in terms of equipment configuration and function, but it is difficult to match with conventional equipment because the configuration is new to existing equipment. For this reason, the technology could not be adopted in equipment planning that assumes coexistence with existing equipment. As described above, it is difficult for the conventional component mounting system to efficiently automate the collection process of the cover tape separated from the carrier tape in the tape feeder with a simple mechanism.

It is configured to include a component mounting device to be mounted on. The cart 11 for supplying components in the present embodiment has a configuration in which a plurality of the tape feeders 13 having the above-described configuration are set and held by the cart holder 7 of the component mounting apparatus 2.

Next, referring to FIG. 2, the overall configuration and functions of the truck 11 will be described. In FIG. 2, the tape feeder 13 includes a feeder front portion 13a fitted in a feeder slot (not shown) formed on the upper surface of the feeder base 12, and a stepped shape rearward from the feeder front portion 13a (left side in FIG. 2). And a feeder rear portion 13b that is provided so as to extend to the inside. The tape feeder 13 is provided with a first transport path 30 that leads from the feeder rear portion 13b to the feeder front portion 13a.

The carrier tape 16 pulled out from the supply reel 15 is introduced into the feeder rear portion 13b and is transported along the first transport path 30. The component to be mounted that has reached the component take-out position 13c by this conveyance is taken out by the mounting head 5 (see FIG. 1). During the transportation of the carrier tape 16, the cover tape 16b covering the component storage portion of the carrier tape 16 is peeled from the carrier tape 16 by the cover tape peeling portion 34 (see FIG. 4). The peeled cover tape 16b is discharged rearward along the second transport path 33 formed in the feeder front portion 13a.

In the present embodiment, the discharge of the peeled cover tape 16b is forcibly collected by a fluid force such as vacuum suction or air blow. That is, the trolley 11 is provided with the cover tape suction nozzles 21 that are provided so as to freely come into contact with and separate from the outlets 33 a (see FIGS. 4 and 5) of the second transport path 33, corresponding to the respective tape feeders 13. ing.

Each cover tape suction nozzle 21 communicates with the duct 20. The cover tape 16b in the second conveyance path 33 is sucked into the duct 20 via the cover tape suction nozzle 21 by vacuum suction of the duct 20 or by air blowing in the duct 20 to generate an air flow. To be done. Both ends of the duct 20 are held by the duct holding portions 14, and the cover tape suction nozzle 21 can be brought into contact with and separated from the feeder front portion 13a by moving the duct holding portions 14 in the front-rear direction.

The base tape 16a, from which the parts have been taken out and which has become empty, is guided downward at the front end of the feeder front part 13a. Further, the base tape 16a reaches the carrier tape cutting section 18 via the chute 17 built in the carriage main body 11a, is cut here, and is collected in the collection container 19 arranged below the carriage main body 11a.

A feeder control section 13e (control section) is built in the feeder rear section 13b. By setting the tape feeder 13 on the feeder base 12, the feeder control unit 13e is connected to the communication unit 11b built in the trolley body 11a via the connecting unit 13d and the feeder base 12. By holding the dolly 11 on the component mounting apparatus 2, the communication unit 11b is connected to the main body control unit 6 (see FIG. 1) built in the base 2a. As a result, the operation of the tape feeder 13 is controlled by the main body control unit 6. That is, the feeder control unit 13e of the tape feeder 13 can communicate with an external device.

Furthermore, an operation panel 13f is provided on the upper surface of the tape feeder 13 for the operator to input and operate. When an operator performs an input operation via the operation panel 13f, it is possible to manually control a predetermined operation such as cutting of the tape feeder 13 for discharging the cover tape 16b.

Next, with reference to FIG. 3, a function of collecting the above-mentioned cover tape 16b provided on the truck 11 will be described. FIG. 3 shows the rear surface of the dolly 11 in FIG. 2, and a plurality of supply reels 15 in which a carrier tape 16 is wound and stored are set in the dolly body 11a. The position of the supply reel 15 corresponds to the position where the tape feeder 13 is set in the feeder base 12, and the carrier tape 16 pulled out from the supply reel 15 is inserted into the feeder rear portion 13b of the tape feeder 13.

In FIG. 3, the duct 20 is a hollow tube having a shape extending in the arrangement direction of the tape feeders 13 in the feeder base 12 and having a suction space 20a inside. A plurality of suction ports 20b for drawing the cover tape 16b into the duct 20 are provided at a plurality of positions on the side surface of the duct 20 corresponding to the tape feeder 13 in the feeder base 12.

At the plurality of positions of the suction port 20b corresponding to the plurality of tape feeders 13 set on the feeder base 12, a plurality of nozzles for individually accessing the tape feeder 13 and guiding the cover tape 16b to the suction port 20b are provided. A cover tape suction nozzle 21 is connected. A blind plug 20c for preventing leakage is attached to the suction port 20b of the suction port 20b corresponding to a position where the tape feeder 13 is not mounted.

Each of the hollow shaft members 22 coupled to both ends of the duct 20 is held by the duct holding portion 14 via a bearing 14a so as to be rotatable about an axis in the horizontal direction. The lower end portion of the duct holding portion 14 is held on the upper surface of the carriage main body portion 11a via a slide mechanism 14b. This allows the duct 20 to move back and forth in the Y direction (the front-back direction in FIG. 2).

The one duct holder 14 (on the left side in FIG. 3) is provided with a feed mechanism 26 configured to convert the rotation of the feed screw mechanism 26a into linear movement in the Y direction. By rotating the feed screw mechanism 26a forward and backward by the handle portion 26b (arrow c), the duct 20 reciprocates in the Y direction together with the duct holding portion 14 holding both ends. As a result, the cover tape suction nozzle 21 mounted on the side surface of the duct 20 can be connected to and separated from the outlet 33a of the second transport path 33 provided in the feeder front portion 13a of the tape feeder 13.

One shaft member 22 (left side in FIG. 3) is connected to the connecting pipe 23 arranged in a vertical posture. The connecting pipe 23 is connected to a cutting section 24 arranged below, and the cutting section 24 is further connected to a suction source 25 arranged below. By operating the suction source 25, the suction space 20a inside the duct 20 is sucked through the connecting pipe 23 (arrow a).

With this, it is possible to perform vacuum suction from the cover tape suction nozzle 21 communicating with the suction space 20a, and vacuum suction the corresponding second feeding path 33 of the tape feeder 13. By this vacuum suction, the cover tape 16b peeled by the cover tape peeling unit 34 (see FIG. 4) and discharged along the second transport path 33 can be collected from the tape feeder 13.

The cover tape 16b sucked by the suction source 25 from the suction space 20a and guided to the connecting pipe 23 is cut into a tape piece by the cutting unit 24 before reaching the suction source 25. The tape piece obtained by cutting the cover tape 16b is guided by the discharge chute 27 and collected in the collecting container 19 provided at the bottom of the carriage main body 11a.

Note that the form of collecting the peeled cover tape 16b is not limited to the form of suction using the suction source 25. For example, as shown in FIG. 3, a blowing device 28 that blows air into the suction space 20a from the opposite side of the connecting pipe 23 to move the air (arrow b) may be provided. With this configuration, an airflow that flows downward from the suction space 20a via the connecting pipe 23 can be generated, and the peeled cover tape 16b can be collected. That is, in this configuration, the cover tape collecting section described above is adapted to move and collect the cover tape 16b by air blow as a fluid force.

As shown in FIGS. 2 and 3, in the configuration for collecting the peeled cover tape 16b, the cover tape suction nozzle 21, the duct 20 to which the cover tape suction nozzle 21 is connected, and the suction source 25 for sucking the inside of the duct 20. Alternatively, the blowing device 28 that moves the air inside the duct 20 constitutes a cover tape collecting unit that collects the cover tapes 16b separated from the plurality of tape feeders 13. In this configuration, the cover tape collecting unit includes the duct 20 that collects the cover tape 16b separated from the tape feeder 13 by using fluid force.

In the above-described configuration, as a mode of utilizing the fluid force, a mode in which the inside of the duct 20 is sucked by the suction source 25, the cover tape 16b is sucked and collected by the duct 20, and an air moving in the duct 20 is used. Any of the form in which the cover tape 16b is moved and recovered by using (air flow) may be used. Alternatively, by using these in combination, a better collection effect of the cover tape 16b can be obtained. It should be noted that the use of fluid force as the cover tape recovery unit is not an essential requirement of the present invention, and may have a function of taking out and recovering the cover tape 16b separated from the tape feeder 13.

That is, in the above-described configuration, the component mounting system 1 (in other words, the component supply cart 11 provided in the component mounting system 1) shown in the present embodiment is peeled off by the tape feeder 13 by using fluid force. The duct 20 is provided for collecting the cover tape 16b. The fluid force used here is generated by the suction source 25 or the blow device 28 which is a fluid force generation source. In the configuration in which the suction source 25 is used as the fluid force generation source, the duct 20 suctions and collects the cover tape 16b. In the configuration in which the blowing device 28 is used as the fluid force generation source, the duct 20 uses the air moving in the duct 20 to move and recover the cover tape 16b.

The dolly 11 in the component mounting system 1 described above has a suction source 25 and a collection container 19 for housing the cover tape 16b collected through the duct 20. In the present embodiment, the recovery container 19 is designed to also recover the carrier tape (base tape 16a) that has been emptied by taking out components (see FIG. 2).

Next, the detailed configuration and functions of the tape feeder 13 will be described with reference to FIG. As shown in FIG. 4A, the tape feeder 13 is provided with a first transport path 30 for guiding the carrier tape 16. The first transport path 30 extends from the insertion port 30a opened on the rear end surface of the feeder rear portion 13b to the feeder front portion 13a along the upper portion of the feeder rear portion 13b. Here, it obliquely moves upward and reaches the component take-out position 13c along the upper surface of the feeder front portion 13a, and then descends along the front end portion of the feeder front portion 13a and reaches the discharge port 30b opened on the lower surface.

A loading unit 31 configured to drive the sprocket 31a by a loading drive unit 31b is arranged at a position near the insertion opening 30a on the rear portion 13b of the feeder. The loading unit 31 has a function of pulling the leading end of the carrier tape 16 pulled out from the supply reel 15 and inserted into the insertion port 30 a of the first transport path 30 to the downstream side of the first transport path 30. There is. The loading section 31 is mounted on the rear portion 13b of the feeder as an expansion unit. That is, the loading function is added to the tape feeder that does not have the loading function (function of pulling the tip end portion of the carrier tape 16 to the carrier tape transport portion 32 located on the downstream side of the first transport path 30) by the expansion unit. You can

A cover tape peeling section 34 is arranged at a position where the first transport path 30 is inclined upward in the feeder front portion 13a. The cover tape peeling unit 34 has a function of peeling the cover tape 16b that covers the upper part of the component storage unit provided in the carrier tape 16 from the carrier tape 16 moving in the first transport path 30.

The cover tape peeling unit 34 is configured to include a pair of rollers 34a sandwiching and feeding the cover tape 16b, and an air blow mechanism 34b for guiding the cover tape 16b between the pair of rollers 34a by air blow. The pair of rollers 34 a is arranged above and in proximity to the first transport path 30. With this configuration, the cover tape peeling unit 34 peels off the cover tape 16b at the tip of the carrier tape 16 that is drawn downstream by the loading unit 31 and moves along the first transport path 30.

That is, the pair of rollers 34a included in the cover tape peeling section 34 can capture the cover tape 16b at the tip of the carrier tape 16 moving in the first transport path 30. Then, the pair of rollers 34a separates the cover tape 16b from the carrier tape 16 by sandwiching the cover tape 16b at the front end sent by the air blow by the air blow mechanism 34b and sending the cover tape 16b away from the carrier tape 16.

On the downstream side of the cover tape peeling section 34 in the feeder front section 13a, a carrier tape transport section 32 configured to drive the two sprockets 32a and 32b by a tape transport drive section 32c is arranged. The carrier tape transport unit 32 has a function of transporting the carrier tape 16 along the first transport path 30 to stop the component storage unit in which the cover tape 16b of the carrier tape 16 is peeled off at the component removal position 13c. is doing.

The feeder front portion 13a is provided with a hollow second conveying path 33 for guiding the cover tape 16b peeled from the carrier tape 16 by the cover tape peeling portion 34. The second transport path 33 has an inlet 33b and an outlet 33a for taking in the peeled cover tape 16b. The inlet 33b is open at a position facing the air blow mechanism 34b. The pair of rollers 34a is arranged at the inlet 33b and feeds the cover tape 16b toward the outlet 33a. The outlet 33a is provided so as to open at the rear end face of the feeder front portion 13a, and is formed at a position accessible by the cover tape suction nozzle 21 that constitutes the above-mentioned cover tape collecting portion (see also FIG. 5). .

An auxiliary blow mechanism 33c that assists the movement of the cover tape 16b sent by the pair of rollers 34a by utilizing the fluid flow may be provided in the second transport path 33. That is, air blow is performed from the auxiliary blow mechanism 33c so as to generate an air flow toward the outlet 33a in the second transport path 33. This assists the movement of the cover tape 16b in the second transport path 33, and the cover tape 16b can be reliably discharged from the outlet 33a without causing the cover tape 16b to be clogged.

A cutting section 35 (cover tape cutting section) is provided near the outlet 33a in the feeder front section 13a. The cutting unit 35 has a function of cutting the cover tape 16b that is peeled off by the tape feeder 13 and guided along the second transport path 33, and includes a cutting blade 35a for cutting the cover tape 16b and a cutting blade 35a. And a drive unit 35b for driving to perform a cutting operation.

The drive unit 35b is driven by a command from the feeder control unit 13e, and the feeder control unit 13e drives the drive unit 35b by an input from the operation panel 13f described above. That is, if there is an input from the operation panel 13f to cut the cover tape 16b, a drive command for cutting is output to the drive unit 35b. As a result, the cover tape 16b discharged from the second transport path 33 can be cut into a desired length.

The feeder control unit 13e is connected to the main body control unit 6 of the component mounting apparatus 2 as shown in FIG. 2 and communicates with an external device (the component mounting apparatus 2 or other equipment connected to the component mounting apparatus 2). It is possible. As a result, when a command to cut the cover tape 16b is received from these external devices, a drive command for cutting is output to the drive unit 35b.

FIG. 4 (b) shows the operations of transporting the carrier tape 16, peeling the cover tape 16 b and discharging the cover tape 16 in the tape feeder 13 having the above configuration. The carrier tape 16 pulled out from the supply reel 15 and inserted into the insertion opening 30 a of the first transport path 30 is transported to the downstream side by the loading unit 31. As a result, the leading end of the carrier tape 16 is drawn to the downstream side of the first transport path 30. Next, when the tip of the carrier tape 16 reaches the position of the cover tape peeling portion 34, the tip of the cover tape 16b is guided between the pair of rollers 34a by the air blow from the air blow mechanism 34b.

The cover tape 16b is separated from the carrier tape 16 by sandwiching the guided cover tape 16b with a pair of rollers 34a and feeding the tape. The peeled cover tape 16b is guided by the second transport path 33 and is transported toward the outlet 33a. At this time, by performing the auxiliary air blow by the auxiliary blow mechanism 33c (arrow e), the cover tape 16b can be more reliably discharged from the outlet 33a (arrow f).

The base tape 16a after the cover tape 16b is peeled off from the carrier tape 16 reaches the component take-out position 13c with the component storage part exposed. Then, here, the component is taken out from the component storage section by the mounting head 5 (see FIG. 1), and the empty base tape 16a is sent downward through the discharge port 30b provided at the front end of the feeder front section 13a. .

FIG. 5 shows a state in which the cover tape suction nozzle 21 constituting the cover tape collecting section is accessed from the feeder front portion 13a of the tape feeder 13. The cover tape suction nozzle 21 includes an extension pipe 21a that extends in the horizontal direction toward the outlet 33a of the second transport path 33. A packing 21b is attached to the tip of the extension pipe 21a. A bellows 21c is provided in the middle of the extension pipe 21a. With the cover tape suction nozzle 21 accessing the feeder front portion 13a, the bellows 21c expands and contracts to reliably press the packing 21b against the outlet 33a. The packing 21b is pressed against the outlet 33a, so that the airtightness of the connecting portion between the extension pipe 21a and the outlet 33a is ensured.

The cutting section 35 provided in the second transport path 33 is stripped from the carrier tape 16 by the cover tape stripping section 34, and cuts the cover tape 16b transported along the second transport path 33. As a result, the cover tape 16b ahead of the cutting position becomes free, and is sucked into the suction space 20a of the duct 20 through the suction port 20b.

Although the present embodiment shows an example in which the cutting unit 35 is arranged on the front side of the outlet 33a in the feeder front portion 13a, the position where the cutting unit 35 is provided is not limited to the example shown here. If it is a position before the cover tape 16b reaches the duct 20, it can be adopted as a position for arranging the cutting portion 35. That is, the cutting portion 35 in the component mounting system 1 shown in the present embodiment is arranged at a position where the cover tape 16b before reaching the duct 20 is cut.

For example, the cutting portion 35 may be arranged in the cover tape suction nozzle 21 in the vicinity of the connection position with the duct 20 as shown by the broken portion 35 in FIG. With such a configuration, it is possible to use a tape feeder having no cutting portion, and it is possible to simplify the form and reduce the facility cost. Further, instead of the cutting unit 35, the cutting unit 24 may be a cover tape cutting unit that cuts the cover tape 16b peeled by the component supply device. In this case, since the tape feeder 13 and the cutting portion 35 of the cover tape suction nozzle 21 can be omitted, further cost reduction can be realized.

However, in this case, when the tape feeder 13 is removed from the dolly 11, the work of pulling out the cover tape 16b pulled into the duct 20 is involved. Therefore, in consideration of the work of removing the tape feeder 13, it is preferable to arrange the cutting portion 35 in a structure capable of cutting the cover tape 16b before reaching the duct 20, that is, in the tape feeder 13 or the cover tape suction nozzle 21.

Next, with reference to FIG. 6, a mode in which the tape feeder 13 is made to access the cover tape suction nozzle 21 and the duct 20 which form the cover tape collecting unit and the access is released will be described. FIG. 6A shows a state in which the duct 20 held by the duct holding portion 14 and the cover tape suction nozzle 21 are slid forward to bring the packing 21b of the extension pipe 21a into close contact with the outlet 33a. In this state, the cover tape suction nozzle 21 is connected to the second transport path 33. The cover tape 16b is collected by the duct 20 shown in FIG. 5 in this state. That is, the position of the duct 20 shown in FIG. 6A is the first position where the cover tape 16b can be collected from the plurality of tape feeders 13.

FIG. 6B shows a state in which the duct 20 held by the duct holding portion 14 and the cover tape suction nozzle 21 are slid backward to separate the packing 21b from the outlet 33a. By operating the feeding mechanism 26 shown in FIG. 3, the cover tape suction nozzle 21 and the duct 20 which constitute the cover tape collecting section are moved backward together with the duct holding section 14 (arrow g).
