Description

Waste tape transport device, waste tape transport system, and mounting device

[0001] This specification discloses a waste tape transport device, a waste tape transport system, and a mounting device.

[0002] A known mounting device includes a component supply unit that supplies components from a tape member that stores a plurality of components, a mounting unit that collects the supplied components, and a waste tape transport device that includes a waste tape transport unit that places the cut waste tape member after the components have been collected on a transport surface and transports it (see, for example, Patent Document 1). Patent Document 1 also describes that the waste tape transport device includes a removal plate that is disposed on the underside of the transport surface at the downstream end of the waste tape transport unit in the transport direction and abuts against the transport surface to remove the waste tape member.

[0003] International Publication No. 2022 / 113191 Pamphlet

[0004] However, in the above-mentioned Patent Document 1, there are cases where the waste tape member is caught between the conveying surface and the removal plate. If the waste tape member does not pass between the conveying surface and the removal plate and remains caught there, that is, if the waste tape member becomes stuck between the conveying surface and the removal plate, a gap is continuously generated between the conveying surface and the removal plate, which reduces the function of the removal plate, and the stuck waste tape member causes wear and abrasion of the conveying surface.

[0005] The present disclosure has been made to solve the above-mentioned problems, and has as its main object to eliminate clogging of waste tape members between the transport surface and the removal plate.

[0006] In order to achieve the above-mentioned main object, the present disclosure has adopted the following means.

[0007] The first waste tape transport device of the present disclosure is a waste tape transport device used in an mounting apparatus that has a component supply unit that supplies components from a tape member that stores a plurality of components, and a mounting unit that collects the supplied components, and comprises: a waste tape transport unit that places the cut waste tape member after the components have been collected on the transport surface of a conveyor belt and transports it, and is configured to be able to hand over the waste tape member to a waste tape transport device or waste tape recovery unit that is adjacent to the downstream side in the transport direction of the waste tape member; a removal plate that abuts against the underside of the transport surface of the waste tape transport unit and removes the waste tape member; and a transport control unit that controls the waste tape transport unit to rotate the conveyor belt in the forward direction and perform a transport process to transport the waste tape member placed on the transport surface downstream in the transport direction, and the transport control unit performs a reverse rotation process to rotate the conveyor belt in the reverse direction when a predetermined condition is met.

[0008] In this first waste tape transport device, when a predetermined condition is met, the transport control unit performs a reverse rotation process that reverses the conveyor belt, unlike the transport process that transports the waste tape material downstream. Therefore, this first waste tape transport device can eliminate clogging of the waste tape material between the transport surface and the removal plate by the reverse rotation process.

FIG. 6 is a partial cross-sectional view of the transport roller 52 and its periphery in the waste tape transport unit 41, cut along the transport direction C. 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, 5, and 6.

[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 the transport 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 a substrate 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 12, 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 printing inspection device that inspects the printing state of the substrate S, a transport device that transports the substrate S, a printing inspection device that inspects the printing 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 12 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 tape material T before it 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 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 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 inlet duct 27, a tape cutter 28, and a discharge duct 29. The inlet 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 inlet 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 apparatus. 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, and also inputs 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 6 , the waste tape transport device 40 includes a waste tape transport unit 41, a blower unit 42, a removal plate 45, a prevention plate 46, a drive unit 47, a control unit 48, and a side prevention plate 58 (see FIGS. 4 and 5 ). The waste tape transport unit 41 is disposed along the transport direction C within the housing of the mounting device 15 and is configured as a belt conveyor that transports the cut waste tape member D after the components P have been picked up. The waste tape transport unit 41 includes transport rollers 51 and 52, a conveyor belt 55, and support members 56 and 57. The transport roller 51 is disposed inside the conveyor belt 55 at the folded-back portion of the upstream end of the transport direction C. The transport roller 52 is disposed inside the conveyor belt 55 at a folded-back portion at the downstream end in the transport direction C. The conveyor belt 55 is stretched from the transport roller 51 to the transport roller 52. The support members 56 and 57 are members that rotatably support a shaft 52a (see FIGS. 5 and 6 ), which is the rotation axis of the transport roller 52. The support members 56 and 57 are disposed on the outer side in the width direction (outer side in the front-to-rear direction in this case) of the conveyor belt 55. Specifically, the support member 56 is disposed behind the conveyor belt 55, and the support member 57 is disposed in front of the conveyor belt 55, and the support members 56 and 57 rotatably support the transport roller 52 from both the front and rear. The support members 56 and 57 are provided with, for example, bearings (not shown) at the portions through which the shaft 52a passes.

[0018] The waste tape transport unit 41 is disposed so that the conveyor belt 55 heads upward toward the downstream side in the transport direction C, i.e., so that the conveyor belt 55 slopes upward. This waste tape transport unit 41 is configured to transport the waste tape member D by placing it on a transport surface 49 (see FIGS. 4 to 6 ), which is the outer circumferential surface of the conveyor belt 55, and to deliver the waste tape member D to a waste tape transport device 40 or waste tape recovery unit 16 adjacent 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 unit 41 can deliver the waste tape member D to an adjacent waste tape transport device 40. As shown in FIG. 3 , the waste tape transport unit 41 is configured so that the ends of adjacent conveyor belts 55 vertically overlap each other. This allows the waste tape transport section 41 to smoothly transfer the waste tape material D to an adjacent waste tape transport section 41, and prevents the waste tape material D from falling from the upstream end of the transport surface 49 of the waste tape transport device 40 to which it is being transferred during the transfer.

[0019] In this way, the mounting system 10 includes a waste tape transport system 11 including a plurality of waste tape transport devices 40 arranged so as to be able to transfer the waste tape material D along the transport direction C. In this embodiment, the plurality of arranged waste tape transport devices 40 are all assumed to have the same configuration. However, for the sake of convenience, when it is necessary to explain the relationship between adjacent waste tape transport devices 40, as shown in FIG. 3 , among the plurality of waste tape transport devices 40, the waste tape transport device 40a, the waste tape transport device 40b adjacent to the downstream side of the waste tape transport device 40a, and the waste tape transport device 40c adjacent to the upstream side of the waste tape transport device 40a may be described separately.

[0020] The removal plate 45 is disposed on the underside of the transport surface 49 downstream of the waste tape transport section 41 in the transport direction C and is a member that abuts against this transport surface 49 to remove the waste tape member D. The removal plate 45 is fixed to a fixed member 45a disposed below the conveyor belt 55. The removal plate 45 is formed of a flexible member such as rubber or resin, and by deforming and abutting against the transport surface 49, the waste tape member D remaining on the transport surface 49 can be efficiently removed and the removal plate 45 can prevent the transport surface 49 of the conveyor belt 55 from being scraped by the removal plate 45. The prevention plate 46 is disposed so as to abut against the upper surface of the transport surface 49 at the upstream end in the transport direction C of the waste tape transport section 41 adjacent to the downstream side. For example, in FIG. 6 , the prevention plate 46 provided in the waste tape transport device 40a abuts against the upper surface of the transport surface 49 at the upstream end in the transport direction C of the waste tape transport device 40b adjacent to the downstream side. As a result, the prevention plate 46 of the waste tape transport device 40a prevents the waste tape member D from moving and falling further upstream than the upstream end of the transport surface 49 of the waste tape transport device 40b. The prevention plate 46 is fixed to a fixing member 46a disposed below the removal plate 45. The prevention plate 46 is formed of a flexible material such as rubber or resin, and is designed to be able to abut in a deformed state against the transport surface 49 of the adjacent waste tape transport unit 41 on the downstream side. In this embodiment, the removal plate 45 and the fixing member 46a are joined, and by joining the fixing member 46a and the prevention plate 46, there is no gap between the contact position between the transport surface 49 of the waste tape transport device 40a and the removal plate 45 and the contact position between the transport surface 49 of the waste tape transport device 40b and the prevention plate 46. Therefore, the waste tape member D can be further prevented from moving further upstream than the upstream end of the transport surface 49 of the waste tape transport device 40b.

[0021] 4 and 5, a side prevention plate 58 is attached to each of the support members 56, 57. The side prevention plate 58 prevents the waste tape member D from falling from the outside in the width direction of the conveyor belt 55 (here, the front or rear of the conveyor belt 55) when the waste tape member D is transferred from one waste tape transport device 40 to another waste tape transport device 40 adjacent to it on the downstream side. Note that the side prevention plate 58 is not shown in FIG. 6.

[0022] The air blower 42 blows air to remove the waste tape member D adhering to the transport surface 49 of the waste tape transport section 41 from the transport surface 49. The air blower 42 includes an ionizer 43, an air outlet 44, piping 59, and a gas supply device (not shown). The air outlet 44 is disposed in support members 56 and 57. Specifically, the air blower 42 includes first to fourth air outlets 44a to 44d as the multiple air outlets 44, with the first air outlet 44a and the second air outlet 44b disposed in the support member 56 and the third air outlet 44c and the fourth air outlet 44d disposed in the support member 57. Therefore, the support members 56 and 57 function as both a part of the waste tape transport section 41 and a part of the air blower 42. The multiple air outlets 44 are formed as through-holes provided in plate-shaped support members 56, 57 located in front of and behind the conveyor belt 55. Each of the multiple air outlets 44 is formed as a through-hole with its axial direction parallel to the width direction, i.e., the front-to-rear direction, of the conveyor belt 55. As a result, the first air outlet 44a and the second air outlet 44b are configured to blow gas in the air blowing direction B1 shown in FIGS. 4 and 5 . The third air outlet 44c and the fourth air outlet 44d are configured to blow gas in the air blowing direction B2 shown in FIG. 5 . The air blowing directions B1 and B2 are both along the width direction, i.e., the front-to-rear direction, of the conveyor belt 55, and in this embodiment, are parallel to the width direction. The air blowing directions B1 and B2 are opposite to each other and face each other across the conveyor surface 49. As a result, each of the multiple air outlets 44 is configured to blow gas toward the conveyor surface 49 along the width direction of the conveyor belt 55. The gas to be blown may be, for example, air. Each of the multiple air outlets 44 is connected to the ionizer 43 and a gas supply device via piping 59 attached to the support members 56 and 57. The gas supply device is, for example, an air compressor, or other device that compresses and supplies gas. This gas supply device also supplies gas to various parts (e.g., air cylinders) within the housing of the mounting device 15. The ionizer 43 irradiates ions onto the gas supplied from the gas supply device and includes an ion irradiation unit (not shown). The ion irradiation unit includes, for example, an electrode, a high-voltage generating circuit, and a power supply.The gas supplied from the gas supply device is irradiated with ions by the ionizer 43 and is supplied to each of the plurality of air outlets 44 via the pipes 59 as compressed air containing ions.

[0023] The arrangement of the multiple air outlets 44 will be described in detail. In this embodiment, the first air outlet 44a and the third air outlet 44c are arranged symmetrically across the conveying surface 49, while the second air outlet 44b and the fourth air outlet 44d are arranged symmetrically across the conveying surface 49. Therefore, the arrangement of the first air outlet 44a and the second air outlet 44b will be described using FIG. 6 , and detailed description of the third air outlet 44c and the fourth air outlet 44d will be omitted. When viewed from the front, the first air outlet 44a and the second air outlet 44b are both located downstream (to the right in this case) in the conveying direction from the contact position (position Q1 in FIG. 6 ) between the removal plate 45 and the conveying surface 49. As a result, the first air outlet 44a and the second air outlet 44b are arranged to blow gas onto the lower surface of the conveying surface 49 downstream in the conveying direction from the contact position with the removal plate 45. The first and second air outlets 44a and 44b open in the same direction but are disposed at different positions. As a result, the first and second air outlets 44a and 44b are disposed so that the portions of the underside of the conveying surface 49 onto which the gas is blown are located at different positions along the length of the conveyor belt 55. The length direction of the conveyor belt 55 is the direction along the surface of the conveyor belt 55 and perpendicular to the width direction of the conveyor belt 55. In this embodiment, the second air outlet 44b is disposed closer to the contact position between the removal plate 45 and the conveying surface 49 than the first air outlet 44a. Furthermore, the first air outlet 44a is disposed so as to blow the gas onto at least a portion of the area F of the underside of the conveying surface 49 in FIG. 6 . Region F is a region from the horizontal end of the folded portion on the downstream side of the underside of the conveying surface 49 in the conveying direction C (the portion of the folded portion of the conveying surface 49 that intersects with horizontal line E passing through the central axis of the conveying roller 52 shown in FIG. 6 ) to the lower end of the folded portion. The second air outlet 44b is arranged to blow gas toward at least a part of region G in FIG. 6 on the underside of the conveying surface 49. Region G is a region from the lower end of the folded portion on the downstream side of the conveying direction C on the underside of the conveying surface 49 to the position where the removal plate 45 and the conveying surface 49 abut.

[0024] The drive unit 47 is a motor that rotates and drives the conveyor belt 55 of the waste tape transport unit 41. The drive unit 47 transmits a driving force to at least one of the transport rollers 51 and 52 to rotate the conveyor belt 55. In this embodiment, as shown in FIG. 5 , the drive unit 47 is disposed in front of the support member 57 and connected to the shaft 52a of the transport roller 52 that penetrates the support member 57, and the drive unit 47 transmits a driving force to the transport roller 52. The control unit 48 is a controller that controls the entire waste tape transport device 40. The control unit 48 outputs a driving signal to the drive unit 47 and the ionizer 43. The control unit 48 also communicates with the control unit 48 of an adjacent waste tape transport device 40 via a communication port (not shown).

[0025] The overlap between adjacent conveyor belts 55 will be described in detail using Figure 6. As shown in Figure 6, the upstream end of the conveyor belt 55 of the waste tape transport device 40b in the transport direction C is disposed below the downstream end of the conveyor belt 55 of the waste tape transport device 40a adjacent to the upstream side of the waste tape transport device 40b in the transport direction C. As a result, the upstream end of the conveyor belt 55 of the waste tape transport device 40b in the transport direction C has an overlap portion OL that vertically overlaps with the downstream end of the conveyor belt 55 of the waste tape transport device 40a in the transport direction C. The overlap portion OL is the portion of the conveyor belt 55 of the waste tape transport device 40b between a vertical line tangent to the upstream end of the conveyor belt 55 of the waste tape transport device 40b and a vertical line tangent to the downstream end of the conveyor belt 55 of the waste tape transport device 40a. Similarly, the upstream end of the conveyor belt 55 of the waste tape transport device 40a has an overlap portion OL that vertically overlaps the downstream end of the conveyor belt 55 of the waste tape transport device 40c that is adjacent to the upstream side of the waste tape transport device 40a. In this embodiment, the contact position between the removal plate 45 and the transport surface 49 (position Q1 in FIG. 6) is located within the overlap portion OL.

[0026] 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 begins, 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 secure 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, repeatedly mounting the components P on the board S. During this mounting process, the CPU 37 also causes the waste tape ejection unit 26 to cut the tape material T and send the resulting waste tape material D to the waste tape transport device 40.

[0027] 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 controls the waste tape transport unit 41 to rotate the conveyor belt 55 in the forward direction, thereby transporting the waste tape member D placed on the transport surface 49 downstream in the transport direction C. The control unit 48 controls the drive unit 47 to rotate the transport roller 52 in the direction of rotation indicated by the arrows in FIGS. 3, 4, and 6, thereby performing the transport process. The control unit 48 also drives the gas supply device and ionizer 43 to supply compressed air containing ions to the air outlet 44. The supplied compressed air is discharged from the air outlet 44 and blown onto the transport surface 49 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 a film that is easily charged with static electricity. For this reason, even if the waste tape transport unit 41 employs a conductive conveyor belt 55, films and the like may stick to the transport surface 49. Furthermore, waste tape members D, such as films, stuck to the transport surface 49 may not fall off the transport surface 49 simply by reaching the underside of the folded portion of the transport surface 49. In this case, in the waste tape transport unit 41 of this embodiment, gas is blown from the air outlet 44 onto the underside of the transport surface 49, and this gas flow can peel the waste tape members D off the transport surface 49, making it easier for them to fall off the transport surface 49. Furthermore, the gas blown from the air outlet 44 contains ions generated by the ionizer 43, so it can neutralize the charge on the waste tape members D, making it easier for the waste tape members D stuck to the transport surface 49 due to static electricity to fall off. Furthermore, the waste tape transport device 40 is equipped with a removal plate 45, which can also be used to peel the waste tape members D off the transport surface 49. As a result, the waste tape member D can be stably transferred from the waste tape transport device 40 to the adjacent waste tape transport device 40 on the downstream side.

[0028] However, during the conveying process, a waste tape member D that does not fall even when exposed to the gas from the air outlet 44 may become caught between the removal plate 45 and the conveying surface 49 and remain stuck there (jammed). For example, as shown in FIG. 7 , if the waste tape member D is an embossed tape having cavities formed therein to accommodate components P, the convex portions where the cavities are formed may not be able to pass between the conveying surface 49 and the removal plate 45, resulting in the waste tape member D becoming jammed. If this condition continues, a continuous gap may be created between the conveying surface 49 and the removal plate 45, reducing the functionality of the removal plate 45, or the jammed waste tape member D may cause wear or abrasion of the conveying surface 49. Furthermore, another waste tape member D may become stuck between the jammed waste tape member D and the conveying surface 49. In response to this, in the waste tape conveying device 40 of this embodiment, the control unit 48 performs a reverse rotation process to reverse the rotation of the conveyor belt 55 when a predetermined condition is met. The control unit 48 performs the reverse rotation process by controlling the drive unit 47 to rotate the transport roller 52 in the rotation direction of the arrow shown in Fig. 7 (the opposite direction to the rotation direction of the arrow shown in Figs. 3, 4, and 6). This reverse rotation process moves the waste tape member D stuck between the transport surface 49 and the removal plate 45 in the opposite direction to that during the transport process (toward the upper right in Fig. 7), thereby clearing the jammed waste tape member D. Predetermined conditions for performing the reverse rotation process include, for example, when the execution time of the transport process has elapsed for a predetermined period of time, or when the transport length of the conveyor belt 55 due to the transport process (including when a value that can be converted into the transport length, such as the number of rotations of the transport roller 52, is used) exceeds a predetermined value, if the reverse rotation process is performed periodically. Furthermore, examples of irregular timing include a condition in which a sensor provided on the outer side of the removal plate 45 in the width direction detects the waste tape member D sandwiched between the removal plate 45 (or a condition in which the waste tape member D sandwiched between the removal plate 45 is detected for a predetermined period of time), a condition in which a sensor detects the lifting of the removal plate 45 (or a condition in which the lifting of the removal plate 45 is detected for a predetermined period of time), etc. When the reverse rotation process is completed, the control unit 48 resumes the transport process.

[0029] The conveyance length of the reverse rotation process is preferably equal to or greater than the conveyance length from the contact position between the removal plate 45 and the conveying surface 49 to the portion of the conveying surface 49 onto which gas is blown from the air outlet 44. In other words, the reverse rotation process is preferably performed so that the waste tape member D at the contact position between the removal plate 45 and the conveying surface 49 moves at least to the portion onto which gas is blown from the air outlet 44. For example, the conveyance length of the reverse rotation process may be equal to or greater than the conveyance length from position Q1 to position Q2 in FIG. 6 . Position Q2 in FIG. 6 is the intersection of a straight line tangent to the end of the second air outlet 44b (the air outlet 44 among the multiple air outlets 44 that is closest to the contact position between the removal plate 45 and the conveying surface 49) on the removal plate 45 side and perpendicular to the conveying surface 49, and the conveying surface 49. At this position Q2, gas is reliably blown from the second air outlet 44b. In reality, the gas blown from the second air outlet 44b flows not only in front of the second air outlet 44b but also outside of it. Therefore, even if the transport length in the reverse rotation process is shorter than the transport length from position Q1 to position Q2, it can be equal to or longer than the transport length from the contact position between the removal plate 45 and the transport surface 49 to the portion of the transport surface 49 onto which the gas is blown from the air outlet 44.

[0030] The transport length of the reverse rotation process may be determined in advance based on, for example, the size of the waste tape member D to be transported. Furthermore, the transport length of the reverse rotation process is preferably equal to or greater than the transport length from the contact position between the removal plate 45 and the transport surface 49 to at least the second-closest point in the longitudinal direction of the conveyor belt 55 to the contact position among the multiple locations where gas is blown. In other words, it is more preferable to perform the reverse rotation process so that the waste tape member D at the contact position between the removal plate 45 and the transport surface 49 moves at least to the locations where gas is blown from the multiple air outlets 44 at least two locations. For example, the transport length of the reverse rotation process may be equal to or greater than the transport length from position Q1 to position Q3 in FIG. 6 . Position Q3 is the intersection of the transport surface 49 and a straight line tangent to the end of the first air outlet 44a (the air outlet 44 second-closest to the contact position between the removal plate 45 and the transport surface 49) on the removal plate 45 side. At this position Q3, gas can be reliably blown from the first air outlet 44a, so that not only the gas from the second air outlet 44b but also the gas from the first air outlet 44a can be blown onto the waste tape member D moving during the reverse rotation process. As described for the second air outlet 44b, the gas blown from the first air outlet 44a actually flows not only in front of the first air outlet 44a but also outside of it. Therefore, even if the transport length during the reverse rotation process is shorter than the transport length from position Q1 to position Q3, it can be set to be equal to or longer than the transport length from the contact position between the removal plate 45 and the transport surface 49 to the second-closest point in the length direction of the conveyor belt 55 to the contact position among the multiple points where gas is blown.

[0031] The transport length of the reverse rotation process is preferably less than the transport length of the overlap portion OL between the waste tape transport device 40 performing the reverse rotation process and the waste tape transport device 40 on its upstream side. The transport length of the overlap portion OL is the transport length from position R1 to position R4 shown in FIG. 6 . Position R1 is a position on the transport surface 49 of the downstream waste tape transport device 40 directly below the downstream end of the conveyor belt 55 of the upstream waste tape transport device 40. Position R4 is the position of the upstream end of the conveyor belt 55 of the downstream waste tape transport device 40. If the transport length of the reverse rotation process is less than the transport length from position R1 to position R4, it is possible to prevent the waste tape member D that has been handed over from the waste tape transport device 40 on the upstream side of the waste tape transport device 40 performing the reverse rotation process and fallen near position R1 from falling from the upstream end of the conveyor belt 55 due to the reverse rotation process. For example, if the transport length of the reverse rotation process performed by the waste tape transport device 40a is too long, it is possible to eliminate clogging of the waste tape member D between the removal plate 45 and the transport surface 49 of the waste tape transport device 40a, but on the other hand, the waste tape member D handed over to the waste tape transport device 40a from the upstream waste tape transport device 40c may be transported too far in the opposite direction to the transport direction C, and may fall from the upstream end of the conveyor belt 55 of the waste tape transport device 40a. In contrast, if the transport length of the reverse rotation process of the waste tape transport device 40a is set to be less than the transport length of the overlap portion OL determined by the positional relationship between the waste tape transport device 40a and the waste tape transport device 40c (the same as the overlap portion OL determined by the positional relationship between the waste tape transport device 40a and the waste tape transport device 40b shown in FIG. 6), it is possible to prevent the waste tape member D from falling from the upstream end of the conveyor belt 55 of the waste tape transport device 40a. The conveying length of the reverse rotation process is preferably less than the conveying length from position R1 to position R3 (the contact position between the conveyor belt 55 and the prevention plate 46), and more preferably less than the conveying length from position R1 to position R2 (the position of the upper end of the folded portion of the conveyor belt 55).

[0032] Here, the correspondence between the components of this embodiment and the components of the present disclosure will be clarified. The waste tape transport unit 41 of this embodiment corresponds to the waste tape transport unit of the present disclosure, the conveyor belt 55 corresponds to the conveyor belt, the transport surface 49 corresponds to the transport surface, the removal plate 45 corresponds to the removal plate, and the control unit 48 corresponds to the transport control unit. Also, the air blower 42 corresponds to the air blower, the air outlet 44 corresponds to the air outlet, the transport roller 52 corresponds to the conveyor transport roller, the waste tape transport system 11 corresponds to the waste tape transport system, the support members 56 and 57 each correspond to a support member, the overlap unit OL corresponds to the overlap unit, the mounting device 15 corresponds to the mounting device, the component supply unit 23 corresponds to the component supply unit, and the mounting unit 30 corresponds to the mounting unit.

[0033] In the waste tape transport device 40 of the present embodiment described above, when a predetermined condition is met, the control unit 48 performs a reverse rotation process of rotating the conveyor belt 55 in the reverse direction, unlike the transport process of transporting the waste tape member D downstream. Therefore, the waste tape transport device 40 can eliminate clogging of the waste tape member D between the transport surface 49 and the removal plate 45 by the reverse rotation process.

[0034] The waste tape transport device 40 also includes an air blower 42 having an air outlet 44 that blows gas along the width direction of the conveyor belt 55 on the underside of the transport surface 49 downstream in the transport direction C of the position where the waste tape transport device 40 abuts the removal plate 45. By blowing gas onto the underside of the transport surface 49 downstream in the transport direction C of the removal plate 45, the waste tape members D are more likely to fall from the transport surface 49, thereby reducing the amount of waste tape members D that do not fall from the transport surface 49 and reach the removal plate 45. This reduces the likelihood of waste tape members D getting stuck between the transport surface 49 and the removal plate 45. Furthermore, by blowing gas onto the underside of the transport surface 49 along the width direction of the conveyor belt 55, the waste tape members D can be more effectively dropped than, for example, when gas is blown along the transport direction C. For example, when blowing gas along the conveyance direction C, it is necessary to arrange multiple air outlets 44 along the width direction of the conveyor belt 55 or to provide air outlets 44 with a wide shape in the width direction, which tends to increase the (total) opening area of ​​the air outlets 44. A large total opening area tends to reduce the pressure of the blown gas or require a gas supply device with a relatively high pressure. In contrast, when blowing gas from the air outlets 44 along the width direction of the conveyor belt 55, it is easy to blow gas to many areas along the width direction of the conveyor belt 55 with one air outlet 44, so it is easy to reduce the (total) opening area of ​​the air outlets 44. As a result, it is easy to increase the pressure of the blown gas or obtain the required pressure with a gas supply device with a relatively low pressure. In other words, when the same gas supply device is used, a higher gas flow rate can be obtained by blowing gas in the width direction compared to blowing in the conveyance direction. Therefore, by blowing gas from the air outlets 44 along the width direction of the conveyor belt 55, the waste tape member D can be effectively dropped. In addition, the advantageous effect of blowing gas along the width direction of the conveyor belt 55 compared to blowing gas along the conveying direction C is particularly high when the width of the conveyor belt 55 is relatively small.

[0035] Furthermore, in the waste tape transport device 40, the air blowing section 42 has a plurality of air blowing ports 44 so that the portions of the underside of the transport surface 49 to which gas is blown are located at different positions along the length of the conveyor belt 55. More specifically, of the plurality of air blowing ports 44, a first air blowing port 44a and a second air blowing port 44b are arranged so as to blow gas at different positions along the length of the conveyor belt 55 on the underside of the transport surface 49. Also, of the plurality of air blowing ports 44, a third air blowing port 44c and a fourth air blowing port 44d are arranged so as to blow gas at different positions along the length of the conveyor belt 55 on the underside of the transport surface 49. By providing such a plurality of air blowing ports 44, the waste tape member D can be more effectively dropped before reaching the removal plate 45. For example, if there is a waste tape member D that does not fall from the underside of the transport surface 49 during the transport process, gas can be blown onto the waste tape member D from two locations, namely, from the first air outlet 44a (and the third air outlet 44c) and the second air outlet 44b (and the fourth air outlet 44d), before the waste tape member D reaches the removal plate 45. Therefore, compared to when gas is blown onto one location, the waste tape member D is more likely to fall from the transport surface 49 before reaching the removal plate 45.

[0036] Furthermore, in the waste tape transport device 40, the multiple air outlets 44 include one or more air outlets 44 (here, first air outlet 44a and third air outlet 44c) arranged to blow gas onto at least a portion of an area F on the underside of the transport surface 49, from the horizontal end of the folded portion on the downstream side in the transport direction C to the lower end of the folded portion, and one or more air outlets 44 (here, second air outlet 44b and fourth air outlet 44d) arranged to blow gas onto at least a portion of an area G from the lower end of the folded portion to the contact position between the removal plate 45 and the transport surface 49. By arranging one or more air outlets 44 corresponding to each of the areas F and G in this manner, the waste tape member D can be more effectively dropped before reaching the removal plate 45. The inventors confirmed this through experiments and analysis.

[0037] In the waste tape transport device 40, the control unit 48, in the reverse rotation process, reverses the conveyor belt 55 by a distance equal to or greater than the transport length from the contact position between the removal plate 45 and the transport surface 49 to the portion of the transport surface 49 where gas is blown from the air outlet 44 (for example, equal to or greater than the transport length from position Q1 to position Q2). As a result, if a waste tape member D is stuck between the transport surface 49 and the removal plate 45, the reverse rotation process can move the waste tape member D to the portion where gas is blown from the air outlet 44, allowing the waste tape member D to fall. Therefore, in this waste tape transport device 40, the waste tape member D stuck between the transport surface 49 and the removal plate 45 can be easily removed from the transport surface 49.

[0038] Furthermore, in the waste tape transport device 40, the control unit 48, in the reverse rotation process, reverses the conveyor belt 55 by at least the transport length from the contact position between the removal plate 45 and the transport surface 49 to at least the second-closest point in the longitudinal direction of the conveyor belt 55 to the contact position among the multiple locations where gas is blown (for example, at least the transport length from position Q1 to position Q3). In this way, if a waste tape member D is stuck between the transport surface 49 and the removal plate 45, the reverse rotation process can be used to blow gas onto the waste tape member D from at least two locations from the multiple air outlets 44, thereby causing the waste tape member D to fall. More specifically, gas can be blown from two locations, namely from the first air outlet 44a (and the third air outlet 44c) and from the second air outlet 44b (and the fourth air outlet 44d), causing the waste tape member D to fall. Therefore, in this waste tape transport device 40 , the waste tape member D stuck between the transport surface 49 and the removal plate 45 can be more easily removed from the transport surface 49 .

[0039] The waste tape transport device 40 also includes a transport roller 52 disposed inside the conveyor belt 55 at a folded portion of the transport surface 49 downstream in the transport direction C, and support members 56, 57 disposed outside the width direction of the conveyor belt 55 and rotatably supporting the transport roller 52. The air outlet 44 is disposed in the support members 56, 57. This allows the support members 56, 57 of the transport roller 52 to double as part of the air blower 42, simplifying the configuration of the waste tape transport device 40. Furthermore, by disposing the air outlet 44 in the support members 56, 57, it is easier to bring the air outlet 44 close to the transport surface 49 of the conveyor belt 55. This enhances the effect of the gas from the air outlet 44 peeling the waste tape member D off the transport surface 49 and dropping it.

[0040] The waste tape transport system 11 of this embodiment also includes a waste tape transport device 40a and a waste tape transport device 40c, which is another waste tape transport device 40 adjacent to the waste tape transport device 40a on the upstream side in the transport direction C and which includes a conveyor belt 55 that transports waste tape members D. Because this waste tape transport system 11 includes the above-mentioned waste tape transport device 40a, it is possible to eliminate clogging of waste tape members D between the transport surface 49 and the removal plate 45 by using a reverse rotation process in the waste tape transport device 40a. Furthermore, in the waste tape transport system 11, the upstream end of the conveyor belt 55 of the waste tape transport device 40a in the transport direction C has an overlap portion OL that is positioned below the downstream end of the conveyor belt 55 of the waste tape transport device 40c in the transport direction C and overlaps vertically with the downstream end. Then, in the reverse rotation process, the control unit 48 of the waste tape transport device 40a reverses the conveyor belt 55 by a length less than the transport length of the overlap portion OL (here, a length less than the transport length from position R1 to position R4). This allows the waste tape transport device 40a of the waste tape transport system 11 to prevent the waste tape member D handed over from the waste tape transport device 40c from falling from the upstream end of the conveyor belt 55 due to the reverse rotation process.

[0041] The mounting device 15 also includes the above-described waste tape transport device 40, a component supply unit 23 that supplies components P from a tape member T that stores a plurality of components P, and a mounting unit 30 that collects the supplied components P. Because the mounting device 15 includes the above-described waste tape transport device 40, it is possible to eliminate clogging of the waste tape member D between the transport surface 49 and the removal plate 45 by the reverse rotation process.

[0042] Furthermore, the mounting device 15 is used in a mounting system 10 in which a plurality of devices are arranged to form a mounting line, and when a mounting line is formed, the waste tape transport unit 41 delivers the waste tape member D to the adjacent waste tape transport device 40 or waste tape recovery unit 16 on the downstream side in the transport direction C of the waste tape member D. In this mounting device 15, the reverse rotation process can eliminate clogging of the waste tape member D between the transport surface 49 and the removal plate 45 in the mounting line. This makes it possible to more reliably transport the waste tape member D to the adjacent waste tape transport device 40 or waste tape recovery unit 16 in the transport direction C.

[0043] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be embodied in various forms as long as they fall within the technical scope of the present disclosure.

[0044] For example, in the above-described embodiment, the waste tape transport device 40 is provided with the first to fourth air outlets 44a to 44d as the plurality of air outlets 44, but the number of air outlets 44 is not limited to this. The number of air outlets 44 is not limited to four as long as there are multiple air outlets, and it may be one.

[0045] In the above-described embodiment, the first air outlet 44a and the third air outlet 44c are arranged symmetrically across the conveying surface 49, and the second air outlet 44b and the fourth air outlet 44d are arranged symmetrically across the conveying surface 49. However, this is not limited to this. For example, the first air outlet 44a and the second air outlet 44b, and the third air outlet 44c and the fourth air outlet 44d may be arranged in a staggered manner, so that the first to fourth air outlets 44a to 44d blow gas to different positions on the underside of the conveying surface 49 along the length of the conveyor belt 55. In this case, there are four portions of the conveying surface 49 to which gas is blown. The positions of the multiple air outlets 44 are also not limited to the above-described embodiment. For example, the air outlets 44 may be arranged to blow gas only to one of region F and region G.

[0046] In the above-described embodiment, the air blowing directions B1 and B2 of the air blowing port 44 are both parallel to the width direction of the conveyor belt 55, but the invention is not limited to this and may be any direction along the width direction. That is, the air blowing direction of the air blowing port 44 may be inclined with respect to the width direction of the conveyor belt 55. The angle of inclination can be determined in advance through experiments or analysis as an angle at which the gas from the air blowing port 44 can peel off the waste tape member D stuck to the transport surface 49.

[0047] In the above-described embodiment, the air outlet 44 is disposed in the support members 56 and 57, but this is not limitative. The air outlet 44 may be disposed in a member other than the support members 56 and 57.

[0048] In the above embodiment, the waste tape transport device 40 has been described as being provided with the prevention plate 46 and the side prevention plate 58, but it may be configured not to be provided with at least one of these.

[0049] In the above-described embodiment, the blower 42 includes the ionizer 43 , but the ionizer 43 may not be included.

[0050] In the above-described embodiment, the multiple waste tape transport devices 40 arranged all have the same configuration, but this is not limited to this. For example, if the waste tape transport device 40a has the configuration of the above-described waste tape transport device 40, the waste tape transport devices 40b and 40c may not have at least part of the configuration of the above-described waste tape transport device 40. For example, the waste tape transport devices 40b and 40c may be devices that do not perform reverse rotation processing, or may be devices that do not have an air outlet 44 that blows gas along the width direction of the conveyor belt 55.

[0051] In the above-described embodiment, when the control unit 48 of the waste tape transport device 40 performs the reverse rotation process, the air blowing unit 42 may blow gas along the transport direction C, and the waste tape transport device 40 may not be provided with the air blowing unit 42. Also, when the waste tape transport device 40 is provided with the air blowing unit 42, the control unit 48 may not be required to perform the reverse rotation process, and the removal plate 45 may not be provided.

[0052] 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 limited to this and may also be a waste tape transport device 40 or a waste tape transport system 11.

[0053] The waste tape conveying device of the present disclosure may be configured as follows.

[0054] The second waste tape transport device of the present disclosure is a waste tape transport device used in an mounting apparatus that includes a component supply unit that supplies components from a tape member that stores a plurality of components, and a mounting unit that collects the supplied components, and includes: a waste tape transport unit that places the cut waste tape member after the components have been collected on the transport surface of a conveyor belt for transport, and is configured to be able to hand over the waste tape member to an adjacent waste tape transport device or waste tape recovery unit downstream in the transport direction of the waste tape member; and an air blower unit that has an air outlet on the underside of the transport surface that blows gas along the width direction of the conveyor belt.

[0055] In this second waste tape transport device, by blowing gas onto the underside of the transport surface, it is possible to make it easier for the waste tape members to fall on the underside of the transport surface. Furthermore, by blowing gas onto the underside of the transport surface along the width direction of the conveyor belt, it is possible to make the waste tape members fall more effectively than when, for example, gas is blown along the transport direction. In this second waste tape transport device, various aspects of the first waste tape transport device described above may be adopted, or components of the first waste tape transport device described above may be added. This specification also discloses a waste tape transport system including this second waste tape transport device, and a mounting device including this second waste tape transport device.
