[0010] The present embodiment will be described below with reference to the drawings. FIG. 1 is a schematic explanatory diagram showing an example of a mounting system 10 and a mounting device 15 according to the present disclosure. FIG. 2 is a configuration diagram showing an outline of the configuration of a waste tape discharge section 26 and a waste tape transport device 40. FIG. 3 is an explanatory diagram showing an example of the configuration of the waste tape transport device 40. FIG. 4 is a perspective view of a connection part of the waste tape transport section 41 as viewed from above. FIG. 5 is a perspective view of a connection part of the waste tape transport section 41 as viewed from below. In this embodiment, the left-right direction (X-axis), the front-rear direction (Y-axis), and the up-down direction (Z-axis) are as shown in FIGS. 1 to 3.

[0011] The mounting system 10 is configured as a mounting line by arranging a plurality of mounting devices 15 for mounting components P on a substrate S as an object to be processed in a conveying direction C of the substrate S. Here, the object to be processed is described as a substrate S, but is not particularly limited as long as the substrate is one on which components P are mounted, and may be a three-dimensional base material. As shown in FIG. 1, the mounting system 10 includes a printing device 11, a mounting device 15, and a waste tape recovery section 16. Note that the mounting system 10 may include, as mounting-related devices, one or more of a printing inspection device for inspecting the printing state of the substrate S, a conveying device for conveying the substrate S, a printing inspection device for inspecting the printing state of the substrate S, a mounting inspection device for inspecting the arrangement state of the components P on the substrate S, a storage device for storing spare feeders 24, and a reflow device for reflowing solder paste. The printing device 11 is a device for printing solder paste or the like on the substrate S.

[0012] The mounting device 15 is a device that picks up components P and mounts them on a board S. As shown in FIGS. 1 and 2 , the mounting device 15 includes a board processing unit 22, a component supply unit 23, a waste tape discharge unit 26, a mounting unit 30, a mounting control unit 36, a communication unit 39, and a waste tape transport device 40.

[0013] The substrate processing unit 22 is a unit that carries in, transports, fixes at the mounting position, and carries out the substrate S. The component supply unit 23 is a unit that supplies the components P to the mounting unit 30. The component supply unit 23 mounts, in one or more mounting units, feeders 24 including reels 25 wound with tape material T (see FIG. 2) as a holding member that holds the components P. The components P are protected by a film that covers the surface of the tape material T, and the film is peeled off to expose the components P before the tape material T is pulled out from the reel 25 and moved to the component P pick-up position. After the components P are picked up, the tape material T and the film are sent to the waste tape discharge unit 26.

[0014] The mounting section 30 is a unit that picks up components P from the component supply section 23 and places them on the board S fixed to the board processing section 22. The mounting section 30 includes a head moving section 31, a mounting head 32, and a nozzle 33. The head moving section 31 includes a slider that is guided by a guide rail and moves in the XY directions, and a motor that drives the slider. The mounting head 32 picks up one or more components P and moves in the XY directions by the head moving section 31. The mounting head 32 is removably attached to the slider. One or more nozzles 33 are removably attached to the underside of the mounting head 32. The nozzle 33 picks up the components P by utilizing negative pressure. The picking member that picks up the components P may be a mechanical chuck that mechanically holds the components P, in addition to the nozzle 33.

[0015] As shown in FIG. 2, the waste tape discharge section 26 includes an introduction duct 27, a tape cutter 28, and a discharge duct 29. The introduction duct 27 is provided behind the feeder 24 attached to the attachment section of the component supply section 23, and is a passage for introducing the tape material T after the components P have been picked. The tape cutter 28 is a device for cutting the tape material T introduced into the introduction duct 27 into small pieces with a cutter. The discharge duct 29 is a passage for discharging the cut waste tape material D. The tape cutter 28 drives the cutter to cut the tape material T into a waste tape material D every time the feeder 24 delivers the tape material T to supply the components P. The waste tape material D cut by the tape cutter 28 is supplied to the waste tape transport device 40 through the discharge duct 29, and is transported to the waste tape recovery section 16 by the waste tape transport device 40. The waste tape collection unit 16 is a device that collects the waste tape members D carried out by the waste tape transport device 40. The waste tape members D collected in the waste tape collection unit 16 may be transported to a waste storage unit outside the device, for example, by negative pressure. In addition, an operator may periodically discard the waste tape members D collected in the waste tape collection unit 16 and the waste tape members D stored in the waste storage unit.

[0016] The mounting control unit 36 ​​is configured as a microprocessor centered on a CPU 37, and controls the entire device. The mounting control unit 36 ​​has a memory unit 38. The memory unit 38 stores mounting condition information (production jobs) including information on components P, the arrangement order in which the components P are mounted on the board S, the arrangement positions, and the mounting positions of the feeder 24 that picks up the components P. The mounting control unit 36 ​​outputs control signals to the board processing unit 22, the component supply unit 23, and the mounting unit 30, while inputting signals from the board processing unit 22, the component supply unit 23, and the mounting unit 30. The communication unit 39 is an interface that exchanges information with external devices.

[0017] The waste tape conveying device 40 is a device that conveys the waste tape member D discharged by the waste tape discharge section 26 to the outside of the device. As shown in Figs. 1 to 5, the waste tape conveying device 40 includes a waste tape conveying section 41, a blower section 42, a removal plate 45, a prevention plate 46, a drive section 47, and a control section 48. The waste tape conveying section 41 is disposed along the conveying direction C in the housing of the mounting device 15, and is disposed to have an upward inclination, and is a conveyor that conveys the cut waste tape member D after the components P are picked. The waste tape conveying section 41 is configured to place the waste tape member D on a conveying surface 49 (see Figs. 4 and 5) and convey it, and to be able to deliver the waste tape member D to the waste tape conveying device 41 or the waste tape recovery section 16 adjacent in the conveying direction C of the waste tape member D. In addition, when the mounting device 15 constitutes a mounting line, the waste tape conveying section 41 is able to deliver the waste tape member D to the adjacent waste tape conveying device 40. The waste tape transport section 41 is configured so that the ends of adjacent conveyor devices overlap vertically, as shown in Fig. 3. This allows the waste tape transport section 41 to smoothly transfer the waste tape member D to the adjacent waste tape transport section 41, and prevents the waste tape member D from falling during the transfer.

[0018] The blower 42 blows air to remove the waste tape member D adhering to the conveying surface 49 of the waste tape conveying section 41 from above the conveying surface 49. As shown in Figs. 4 and 5, the blower 42 is configured to blow air in the blowing direction B along the conveying direction C to the lower conveying surface 49 of the downstream end of the waste tape conveying section 41 in the conveying direction C. The blower 42 is fixed near and below the removal plate 45 that abuts against the lower conveying surface 49. The blower 42 is also fixed behind the prevention plate 46 that abuts against the conveying surface 49 of the adjacent waste tape conveying section 41. That is, the blower 42 is provided at a position between the waste tape conveying section 41 and the adjacent waste tape conveying section 41 or the waste tape recovery section 16 that is disposed below the waste tape conveying section 41 when the waste tape conveying device 40 constitutes a mounting line. The blower 42 is also provided between the removal plate 45 and the prevention plate 46. The blower 42 is composed of a flow pipe 43, an air outlet 44, and a gas supply device (not shown). The flow pipe 43 is disposed on the lower surface side of the transport surface 49 of the waste tape transport section 41, and is formed in a direction perpendicular to the transport direction C, and allows gas to flow. The gas to be circulated may be air, for example. The air outlet 44 is an opening formed in the flow pipe 43 toward the transport surface 49 at the downstream end of the waste tape transport section 41 in the transport direction C, and a plurality of air outlets are formed along the flow pipe 43 over the entire width of the transport surface 49. The gas supply device is, for example, an air compressor, which compresses and supplies gas. The gas supply device also supplies gas to various parts (for example, air cylinders) in the housing of the mounting device 15.

[0019] The removal plate 45 is a member disposed on the lower surface side of the conveying surface 49 at the downstream end of the waste tape conveying section 41 in the conveying direction C, and abuts against this conveying surface 49 to remove the waste tape member D. The removal plate 45 is fixed to a fixed member 45a joined along the upper side of the flow pipe 43 to the upper side of the flow pipe 43. The removal plate 45 is formed of a flexible member such as rubber or resin. The prevention plate 46 is disposed on the upper surface side of the conveying surface 49 at the upstream end of the adjacent waste tape conveying section 41 in the conveying direction C, and abuts against this conveying surface 49 to prevent the waste tape member D from entering. The prevention plate 46 is fixed to a fixed member 46a joined along the flow pipe 43 to the lower side of the flow pipe 43. The prevention plate 46 is formed of a flexible member such as rubber or resin. The blower section 42 is joined to the removal plate 45 via the fixed member 45a, and is also joined to the prevention plate 46 via the fixed member 46a.

[0020] The drive unit 47 is a motor that is connected to the drive shaft of the conveyor of the waste tape transport unit 41 and drives it to rotate. The control unit 48 is a controller that controls the entire waste tape transport device 40. The control unit 48 outputs a drive signal to the drive unit 47. In addition, the control unit 48 communicates with the control unit 48 of the adjacent waste tape transport device 40 via a communication port (not shown).

[0021] Next, the operation of the mounting system 10 of this embodiment thus configured, first, the process in which the mounting device 15 mounts the component P on the board S will be described. When the CPU 37 of the mounting control unit 36 ​​starts the mounting process, it reads out the mounting condition information, which is a production job, from the storage unit 38, and controls the board processing unit 22 to carry in and fix the board S. Next, the CPU 37 performs a process of having the mounting head 32 pick up the component P from the feeder 24 attached to the component supply unit 23 based on the mounting condition information, and arranging the picked component P at a predetermined position on the board S. When the arrangement of the component P on the board S is finished, the CPU 37 ejects the board S to the board processing unit 22, and as described above, has the next board S carried in the board processing unit 22, and repeats the process of mounting the component P on the board S. Also, during this mounting process, the CPU 37 performs a process of cutting the tape material T by the waste tape ejection unit 26, and sending the generated waste tape material D to the waste tape conveying device 40.

[0022] Next, a process of conveying the waste tape member D to the waste tape recovery section 16 will be described. When the above-mentioned mounting process is started, the control section 48 drives the drive section 47 to operate the waste tape conveying section 41 and conveys the waste tape member D in the conveying direction C. The control section 48 also drives the gas supply device to supply compressed air to the flow pipe 43. The supplied compressed air is discharged from the air outlet 44 and blown onto the conveying surface 49 at the rear end of the waste tape conveying section 41. The waste tape member D sent from the waste tape discharge section 26 is placed on the conveying surface 49 of the waste tape conveying section 41 and conveyed in the conveying direction C. For example, the waste tape member D includes a resin tape in which a cavity for accommodating the component P is formed, as well as a film that is easily charged with static electricity. For this reason, even if the waste tape conveying section 41 employs a conductive conveyor belt, the film may stick to the conveying surface 49. In addition, the waste tape transport section 41 uses a removal plate 45, which makes it possible to peel off most of the waste tape member D, but the film is thin and can get caught between the removal plate 45 and the conveyor belt, and the film can get into the gap. This waste tape transport section 41 has an air blower 42 on the rear side of the tip, which can blow air onto the transport surface 49, making it possible to sufficiently peel off such waste tape member D, such as film, from the transport surface 49. In addition, in the waste tape transport section 41, there are no gaps due to the prevention plate 46, so it is possible to prevent the waste tape member D from getting into the gaps between the waste tape transport sections 41.

[0023] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. The waste tape transport section 41 of this embodiment corresponds to the waste tape transport section of the present disclosure, and the blower section 42 corresponds to the blower section. In addition, the circulation pipe 43 corresponds to the circulation pipe, the blower port 44 corresponds to the blower port, the removal plate 45 corresponds to the removal plate, and the prevention plate 46 corresponds to the prevention plate.

[0024] The waste tape transport device 40 of the present embodiment described above transports the waste tape member D by the waste tape transport section 41 configured to be able to deliver the waste tape member D to the adjacent waste tape transport device 40 or the waste tape recovery section 16. In this waste tape transport device 40, the waste tape member D is prevented from remaining attached to the transport surface 49 by blowing gas such as air in a direction along the transport direction C to the transport surface 49 on the lower surface side of the downstream end of the waste tape transport section 41 in the transport direction C. Therefore, in this waste tape transport device 40, it is possible to further suppress the waste tape member D from falling from the gap between the waste tape transport devices 40, for example, and to transport the waste tape member D in a direction other than the transport path, and the waste tape member D can be transported stably.

[0025] The air blowing section 42 is provided between the waste tape transport section 41 and the adjacent waste tape transport section 41 disposed below the waste tape transport section 41. In this waste tape transport device 40, it is possible to prevent the waste tape member D from entering between the adjacent waste tape transport sections 41 disposed above and below. Furthermore, the air blowing section 42 is configured by a circulation pipe 43 disposed on the lower surface side of the transport surface 49 of the waste tape transport section 41 and circulating gas formed in a direction perpendicular to the transport direction C, and an air blowing port 44 formed in the circulation pipe 43. In this waste tape transport device 40, the waste tape member D can be transported more stably with a simple configuration of the circulation pipe 43 and the air blowing port 44. Furthermore, the waste tape transport device 40 includes a removal plate 45 disposed on the lower surface side of the transport surface 49 at the downstream end of the waste tape transport section 41 in the transport direction C, which abuts against the transport surface 49 to remove the waste tape member D, and a prevention plate 46 disposed on the upper surface side of the transport surface 49 at the upstream end of the adjacent waste tape transport section 41 in the transport direction C, which abuts against the transport surface 49 to prevent the waste tape member D from entering. The air blowing section 42 is disposed between the removal plate 45 and the prevention plate 46. In this waste tape transport device 40, the removal plate 45 and the prevention plate 46 can be used to prevent the waste tape member D from entering places other than the transport path. The air blowing section 42 is joined to the removal plate 45 and the prevention plate 46 via the fixing member 45a and the fixing member 46a. This waste tape transport device 40 has a structure in which the removal plate 45, the air blower 42, and the prevention plate 46 are joined together, and can further prevent the waste tape from entering any place other than the transport path.

[0026] The mounting device 15 also includes a component supplying section 23 that supplies components P from a tape member T that contains a plurality of components P, a mounting section 30 that collects the supplied components P, and the waste tape transporting device 40 described above. Since the mounting device 15 includes the waste tape transporting device 40 described above, the waste tape member D can be transported stably. In addition, the mounting device 15 can obtain an effect according to the aspect of the waste tape transporting device 40 employed. In addition, the mounting device 15 is used in a mounting system 10 that configures a mounting line by arranging a plurality of mounting devices 15, and when a mounting line is configured, the waste tape transporting section 41 delivers the waste tape member D to the waste tape transporting device 40 or the waste tape collecting section 16 adjacent in the transport direction C of the waste tape member D. In the mounting device 15, the waste tape member D can be transported stably in the mounting line.

[0027] It goes without saying that the present disclosure is in no way limited to the above-described embodiment, and can be embodied in various forms as long as it falls within the technical scope of the present disclosure.

[0028] For example, in the above embodiment, the air blower 42 is disposed at a position between the waste tape transport section 41 and the adjacent waste tape transport section 41 or the waste tape recovery section 16, but the positional relationship with the adjacent device is not particularly limited. For example, the air blower 42 may be disposed on the underside of the downstream end of the waste tape member D in the transport direction C.

[0029] In the above-described embodiment, the air blowing section 42 includes the flow pipe 43 and the air blowing port 44, but is not limited to this structure as long as it can blow air to the lower conveying surface 49. For example, the air blowing section 42 may be configured with an air blowing fan. In such a waste tape conveying device 40, it is possible to further prevent the waste tape member D from moving to a location other than the conveying path, and the waste tape member D can be conveyed stably.

[0030] In the above embodiment, the waste tape transport device 40 has been described as including the removal plate 45, but is not particularly limited thereto, and may not include the removal plate 45. In this waste tape transport device 40 as well, the waste tape member D can be removed from the transport surface 49 by the blower 42, and the waste tape member D can be further prevented from moving to directions other than the transport path. It is preferable that the waste tape transport device 40 has the removal plate 45, since this can further prevent the waste tape member D from moving to directions other than the transport path.

[0031] In the above embodiment, the waste tape transport device 40 has been described as including the prevention plate 46, but it may not be provided with the prevention plate 46. Even in this waste tape transport device 40, the waste tape member D can be moved to the next waste tape transport section 41 or the waste tape recovery section 16 by the blower 42, so that the waste tape member D can be further prevented from moving to directions other than the transport path. Note that it is preferable for the waste tape transport device 40 to have the prevention plate 46, since this can further prevent the waste tape member D from moving to directions other than the transport path.

[0032] In the above embodiment, the blower 42 has been described as being joined to the removal plate 45 and the prevention plate 46 via the fixing members 45a and 46a, but this is not particularly limited, and the blower 42 may not be joined to the removal plate 45 and the prevention plate 46. In this waste tape transport device 40, the blower 42 can also move the waste tape member D to the next waste tape transport section 41 or the waste tape recovery section 16, so that the waste tape member D can be further prevented from moving to a location other than the transport path. Note that it is preferable for the waste tape transport device 40 to have a structure joined to the removal plate 45 and the prevention plate 46, since this can further prevent the waste tape member D from moving to a location other than the transport path.

[0033] Although not specifically described in the above embodiment, for example, the waste tape transport device 40 may be provided with an inclination change mechanism capable of changing the inclination direction of the waste tape transport section 41, the drive section 47 may be configured so that the conveyor shaft can be reversed, and the blower section 42 may be configured so that it can be removed and attached to any end of the waste tape transport section 41. There are cases where the mounting system 10 needs to change the arrangement position of the waste tape recovery section 16 and the transport direction C depending on the arrangement direction, etc. In this waste tape transport device 40, the transport direction of the waste tape material D can be easily changed.

[0034] In the above-described embodiment, a mounting device 15 equipped with a waste tape transport device 40 and a mounting system 10 having a mounting device 15 equipped with a waste tape transport device 40 have been described, but this is not particularly limited to this and the waste tape transport device 40 may also be used.
