[0010] This 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 unit 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 the connecting portion of the waste tape transport unit 41 as seen from above. FIG. 5 is a perspective view of the connecting portion of the waste tape transport unit 41 as seen from below. In this embodiment, the left-right direction (X-axis), front-rear direction (Y-axis), and up-down direction (Z-axis) are as shown in FIGS. 1 to 3.

[0011] The mounting system 10 is configured as a mounting line, for example, by arranging multiple mounting devices 15, each of which mounts components P on a substrate S as a processing object, in a conveying direction C of the substrate S. Here, the processing object is described as a substrate S, but is not particularly limited as long as it is something on which components P are mounted, and it may also be a three-dimensional substrate. As shown in FIG. 1 , the mounting system 10 is configured to include a printing device 11, a mounting device 15, and a waste tape recovery unit 16. Note that the mounting system 10 may also include, as mounting-related devices, one or more of a print inspection device that inspects the printed state of the substrate S, a transport device that transports the substrate S, a print inspection device that inspects the printed state of the substrate S, a mounting inspection device that inspects the placement state of the components P on the substrate S, a storage device that stores spare feeders 24, and a reflow device that reflows solder paste. The printing device 11 is a device that prints 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 loads, transports, fixes at the mounting position, and loads out the substrate S. The component supply unit 23 is a unit that supplies components P to the mounting unit 30. This component supply unit 23 has feeders 24, each of which includes a reel 25 wound with a tape material T (see FIG. 2) serving as a holding member for holding the components P, attached to one or more attachment units. The components P are protected by a film covering 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 have been picked up, the tape material T and the film are sent to the waste tape discharge unit 26.

[0014] The mounting unit 30 is a unit that picks up components P from the component supply unit 23 and places them on a board S fixed to the board processing unit 22. The mounting unit 30 includes a head moving unit 31, a mounting head 32, and a nozzle 33. The head moving unit 31 includes a slider that moves in the X and Y directions along a guide rail, and a motor that drives the slider. The mounting head 32 picks up one or more components P and moves it in the X and Y directions by the head moving unit 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 nozzles 33 pick up the components P using negative pressure. Note that 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 up. The tape cutter 28 is a device that cuts the tape material T introduced into the introduction duct 27 into small pieces using 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 waste tape material D every time the feeder 24 feeds out 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 transported to the waste tape collection 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 to be mounted on the board S, their arrangement positions, and the mounting positions of the feeders 24 that pick 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 receiving 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 transport device 40 is a device that transports the waste tape member D discharged by the waste tape discharge unit 26 to the outside of the device. As shown in FIGS. 1 to 5, the waste tape transport device 40 includes a waste tape transport 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 transport section 41 is disposed within the housing of the mounting device 15 along the transport direction C, and is disposed so as to slope upward. The waste tape transport section 41 is a conveyor that transports the waste tape member D that has been cut after the components P have been picked up. The waste tape transport section 41 places the waste tape member D on a transport surface 49 (see FIGS. 4 and 5) and transports it. The waste tape member D is configured to be able to deliver the waste tape member D to an adjacent waste tape transport device 41 or waste tape recovery section 16 in the transport direction C of the waste tape member D. Furthermore, when the mounting device 15 forms a mounting line, the waste tape transport section 41 is able to deliver the waste tape member D to an adjacent waste tape transport device 40. The waste tape transporting section 41 is configured so that the ends of adjacent conveyor devices overlap vertically, as shown in Fig. 3. This allows the waste tape transporting section 41 to smoothly transfer the waste tape member D to the adjacent waste tape transporting section 41, and prevents the waste tape member D from falling during the transfer.

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

[0019] The removal plate 45 is disposed on the underside of the conveying surface 49 at the downstream end of the waste tape conveying section 41 in the conveying direction C, and is a member that abuts against this conveying surface 49 to remove the waste tape member D. The removal plate 45 is fixed to a fixing member 45a that is joined along the upper side of the flow pipe 43 to the flow pipe 43. The removal plate 45 is made of a flexible member such as rubber or resin. The prevention plate 46 is disposed on the upper side of the conveying surface 49 at the upstream end of the adjacent waste tape conveying section 41 in the conveying direction C, and is a member that abuts against this conveying surface 49 to prevent the waste tape member D from entering. The prevention plate 46 is fixed to a fixing member 46a that is joined along the lower side of the flow pipe 43 to the flow pipe 43. The prevention plate 46 is made of a flexible member such as rubber or resin. The blower section 42 is joined to the removal plate 45 via the fixing member 45a, and is also joined to the prevention plate 46 via the fixing 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, this control unit 48 communicates with the control unit 48 of an adjacent waste tape transport device 40 via a communication port (not shown).

[0021] Next, the operation of the mounting system 10 of this embodiment configured as described above will be described. First, the process in which the mounting device 15 mounts components P on the board S will be described. When the mounting process starts, the CPU 37 of the mounting control unit 36 ​​reads mounting condition information, which is a production job, from the storage unit 38 and controls the board processing unit 22 to load and fix the board S. Next, based on the mounting condition information, the CPU 37 causes the mounting head 32 to pick up components P from the feeder 24 attached to the component supply unit 23 and place the picked components P in predetermined positions on the board S. After the components P have been placed on the board S, the CPU 37 ejects the board S to the board processing unit 22 and, as described above, loads the next board S into the board processing unit 22, and repeats the process of mounting components P on the board S. During this mounting process, the CPU 37 also causes the waste tape discharge unit 26 to cut the tape material T and send the resulting waste tape material D to the waste tape transport device 40.

[0022] Next, the process of transporting the waste tape member D to the waste tape collection unit 16 will be described. When the above-described mounting process is started, the control unit 48 drives the drive unit 47 to operate the waste tape transport unit 41 and transport the waste tape member D in the transport direction C. The control unit 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 transport surface 49 at the rear end of the waste tape transport unit 41. The waste tape member D sent from the waste tape discharge unit 26 is placed on the transport surface 49 of the waste tape transport unit 41 and transported in the transport direction C. For example, the waste tape member D may include not only a resin tape formed with cavities for accommodating components P, but also a film that is easily charged with static electricity. For this reason, even if the waste tape transport unit 41 uses a conductive conveyor belt, the film may stick to the transport surface 49. Furthermore, 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 film is thin and can get caught between the removal plate 45 and the conveyor belt, and the film can also get into the gap. This waste tape transport section 41 has an air blower 42 on the rear side of the tip, which blows 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. Furthermore, 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 air blower section 42 corresponds to the air blower section. Also, the circulation pipe 43 corresponds to the circulation pipe, the air blower port 44 corresponds to the air 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 transporting device 40 of the present embodiment described above transports the waste tape member D by a waste tape transporting section 41 configured to be able to deliver the waste tape member D to an adjacent waste tape transporting device 40 or a waste tape recovery section 16. In this waste tape transporting device 40, a gas such as air is blown in a direction along the transport direction C onto a transport surface 49 on the underside of the downstream end of the waste tape transporting section 41 in the transport direction C, thereby preventing the waste tape member D from remaining stuck to the transport surface 49. Therefore, in this waste tape transporting device 40, it is possible to further prevent the waste tape member D from falling from a gap between the waste tape transporting devices 40, or from moving outside the transport path, and the waste tape member D can be transported stably.

[0025] Furthermore, the air blowing section 42 is provided between the waste tape transport section 41 and an adjacent waste tape transport section 41 disposed below this 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 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 underside of the transport surface 49 of the waste tape transport section 41 and for 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 below the transport surface 49 at the downstream end of the waste tape transport section 41 in the transport direction C, and abutting against this transport surface 49 to remove the waste tape member D, and a prevention plate 46 disposed above the transport surface 49 at the upstream end of the adjacent waste tape transport section 41 in the transport direction C, and abutting against this transport surface 49 to prevent the waste tape member D from entering. The air blower 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 blower 42 is joined to the removal plate 45 and the prevention plate 46 via fixing members 45a and 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 places other than the transport path.

[0026] The mounting apparatus 15 also includes a component supply unit 23 that supplies components P from a tape member T that stores a plurality of components P, a mounting unit 30 that collects the supplied components P, and the waste tape transport device 40 described above. This mounting apparatus 15 is equipped with the waste tape transport device 40 described above, and is therefore capable of stably transporting the waste tape member D. This mounting apparatus 15 also provides effects that correspond to the type of waste tape transport device 40 employed. A plurality of mounting apparatuses 15 are arranged in a mounting system 10 that constitutes a mounting line, and when a mounting line is constituted, the waste tape transport unit 41 delivers the waste tape member D to the waste tape transport device 40 or waste tape recovery unit 16 that is adjacent in the transport direction C of the waste tape member D. This mounting apparatus 15 is capable of stably transporting the waste tape member D on the mounting line.

[0027] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be implemented in various forms as long as they fall within the technical scope of the present disclosure.

[0028] For example, in the above-described 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 collection 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 is provided with the flow pipe 43 and the air blowing port 44, but is not particularly 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 a blowing fan. In such a waste tape conveying device 40, it is also possible to further prevent the waste tape member D from moving outside the conveying path, and the waste tape member D can be conveyed stably.

[0030] In the above-described embodiment, the waste tape transport device 40 has been described as including the removal plate 45, but is not particularly limited to this 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 air 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-described embodiment, the waste tape transport device 40 has been described as being provided with the prevention plate 46, but it may not be provided with the prevention plate 46. In this waste tape transport device 40 as well, the waste tape member D can be moved to the next waste tape transport section 41 or the waste tape collection section 16 by the air blower 42, so it is possible to further prevent the waste tape member D from moving to places other than the transport path. Note that it is preferable for the waste tape transport device 40 to have the prevention plate 46, as this can further prevent the waste tape member D from moving to places other than the transport path.

[0032] In the above-described embodiment, the air blower 42 is described as being joined to the removal plate 45 and the prevention plate 46 via the fixing members 45a, 46a, but this is not particularly limited, and the air blower 42 may not be joined to the removal plate 45 or the prevention plate 46. In this waste tape transport device 40, the air blower 42 can also move the waste tape member D to the next waste tape transport section 41 or the waste tape collection section 16, so it is possible to further prevent the waste tape member D from moving outside 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, as this can further prevent the waste tape member D from moving outside the transport path.

[0033] Although not specifically described in the above-described embodiment, for example, the waste tape transport device 40 may be provided with an inclination change mechanism that can change the inclination direction of the waste tape transport section 41, the drive section 47 may be configured to be able to reverse the conveyor axis, and the air blower section 42 may be configured to be detachable and attachable to either end of the waste tape transport section 41. The mounting system 10 may need to change the placement position of the waste tape recovery section 16 and the transport direction C depending on the placement 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, an implementation system 10 is described as having an implementation device 15 equipped with a waste tape transport device 40, and an implementation system 10 having an implementation device 15 equipped with a waste tape transport device 40, but this is not particularly limited to this, and the implementation system 10 may also be a waste tape transport device 40.
