Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in Patent Document 1 described above, for example, when the waste tape member is a material that easily becomes electrostatically charged, the waste tape member may remain attached to the conveying surface of the waste tape conveying device. If the waste tape member remains attached to the conveying surface, the waste tape member does not fall from the conveying surface, and problems may occur, such as the inability to transfer it to, for example, the next waste tape conveying device.
[0005] This disclosure has been made to solve the above-described problems, and the main object is to make it easier for the waste tape member to fall on the lower surface side of the conveying surface.
Means for Solving the Problems
[0006] This disclosure has adopted the following means to achieve the above-described main object.
[0007] The waste tape conveying device of the present disclosure is a waste tape conveying device used in a mounting device including a component supply unit that supplies components from a tape member that houses a plurality of components, and a mounting unit that picks up the supplied components, a waste tape conveying unit configured to place and convey a cut waste tape member after the components have been picked up on the conveying surface of a conveyor belt, and to be able to transfer the waste tape member to a waste tape conveying device or a waste tape collection unit adjacent to the conveying direction of the waste tape member, and includes the waste tape conveying unit having a convex portion and / or a concave portion on the lower surface side of the conveying surface. It is such.
[0008] In this waste tape conveying device, the waste tape conveying unit has a convex portion and / or a concave portion on the lower surface side of the conveying surface of the conveyor belt. Thereby, in this waste tape conveying device, the contact area between the waste tape member and the conveying surface can be reduced by the convex portion and / or the concave portion. Therefore, in this waste tape conveying device, it is possible to make it easier for the waste tape member to fall on the lower surface side of the conveying surface.

Mode for Carrying Out the Invention
[0010] This embodiment will be described below with reference to the drawings. FIG. 1 is a schematic explanatory view showing an example of the mounting system 10 and the mounting device 15 disclosed in the present disclosure. FIG. 2 is a configuration diagram showing an outline of the configuration of the waste tape discharge unit 26 and the waste tape transport device 40. FIG. 3 is an explanatory view 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 viewed from above. FIG. 5 is a perspective view of the connecting portion of the waste tape transport unit 41 as viewed from below. FIG. 6 is a partial cross-sectional view of the waste tape transport unit 41 in which the transport roller 52 and its periphery are 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.
[0011] The mounting system 10 is configured as a mounting line, for example, by arranging a plurality of mounting devices 15 for mounting components P on a substrate S as an object to be processed in the transport direction C of the substrate S. Here, the object to be processed is described as the substrate S, but it is not particularly limited as long as it mounts the component P, and it may be a three-dimensional shaped base material. As shown in FIG. 1, this mounting system 10 includes a printing device 11, a mounting device 15, and a waste tape collection unit 16. Note that the mounting system 10 may include, as mounting-related devices, for example, one or more of a printing inspection device for inspecting the printing state of the substrate S, a transport device for transporting 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 component P on the substrate S, a storage device for storing a spare feeder 24, and a reflow device for reflowing the 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 the component P and mounts it on the substrate S. As shown in FIGS. 1 and 2, the mounting device 15 includes a substrate 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 performs loading, transport, fixing at the mounting position, and unloading of the substrate S. The component supply unit 23 is a unit that supplies the component P to the mounting unit 30. This component supply unit 23 mounts one or more feeders 24 including a reel 25 around which a tape member T (see FIG. 2) as a holding member holding the component P is wound, on one or more mounting portions. The component P is protected by a film covering the surface of the tape member T, and the film is peeled off and exposed before the tape member T is pulled out from the reel 25 and moved to the picking position of the component P. The tape member T and the film after the component P is picked up are sent to the waste tape discharge unit 26.
[0014] The mounting unit 30 is a unit that picks up the component P from the component supply unit 23 and places it on the substrate S fixed to the substrate 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 guided by a guide rail and moving in the XY direction, and a motor for driving the slider. The mounting head 32 picks up one or more components P and moves in the XY direction by the head moving unit 31. This mounting head 32 is detachably mounted on the slider. One or more nozzles 33 are detachably mounted on the lower surface of the mounting head 32. The nozzle 33 picks up the component P using negative pressure. Note that the picking member for picking up the component P may be a mechanical chuck that mechanically holds the component P in addition to the nozzle 33.
[0015] As shown in FIG. 2, the waste tape discharging unit 26 includes an introduction duct 27, a tape cutting machine 28, and a discharge duct 29. The introduction duct 27 is provided behind the feeder 24 mounted on the mounting portion of the component supply unit 23, and is a passage for introducing the tape member T after the component P has been picked up. The tape cutting machine 28 is a device that finely cuts the tape member T introduced into the introduction duct 27 with a cutter. The discharge duct 29 is a passage for discharging the cut waste tape member D. The tape cutting machine 28 drives the cutter to cut the tape member T into the waste tape member D each time the feeder 24 feeds out the tape member T for supplying the component P. The waste tape member D cut by the tape cutting machine 28 is supplied to the waste tape conveying device 40 through the discharge duct 29, and is conveyed to the waste tape collecting unit 16 by the waste tape conveying device 40. The waste tape collecting unit 16 is a device that collects the waste tape member D carried out by the waste tape conveying device 40. The waste tape member D collected by the waste tape collecting unit 16 may be conveyed to a waste storage unit outside the device, for example, by negative pressure or the like. Also, the operator may periodically discard the waste tape member D collected by the waste tape collecting unit 16 and the waste tape member D stored in the waste storage unit.
[0016] The mounting control unit 36 is configured as a microprocessor centered around the CPU 37 and controls the entire apparatus. The mounting control unit 36 has a storage unit 38. The storage unit 38 stores mounting condition information (production job) including information on the component P, the arrangement order, arrangement position for mounting the component P on the substrate S, the mounting position of the feeder 24 for picking up the component P, and the like. This mounting control unit 36 outputs control signals to the substrate processing unit 22, the component supply unit 23, and the mounting unit 30, while inputting signals from the substrate processing unit 22, the component supply unit 23, and the mounting unit 30. The communication unit 39 is an interface for exchanging information with external devices.
[0017] The waste tape conveying device 40 is a device that conveys the waste tape member D discharged at the waste tape discharge unit 26 outside the device. As shown in FIGS. 1 to 6, the waste tape conveying device 40 includes a waste tape conveying unit 41, a blowing unit 42, a removal plate 45, a prevention plate 46, a driving unit 47, and a control unit 48. The waste tape conveying unit 41 is disposed along the conveying direction C within the housing of the mounting device 15 and is configured as a belt conveyor that conveys the cut waste tape member D after the component P has been picked up. The waste tape conveying unit 41 includes conveying rollers 51, 52 and a conveyor belt 55. The conveying roller 51 is disposed inside the conveyor belt 55 at the upstream end in the conveying direction C. The conveying roller 52 is disposed inside the conveyor belt 55 at the downstream end in the conveying direction C. The conveyor belt 55 is stretched from the conveying roller 51 to the conveying roller 52. The waste tape conveying unit 41 is disposed such that the conveyor belt 55 is directed upward toward the downstream side in the conveying direction C, that is, the conveyor belt 55 has an ascending inclination. This waste tape conveying unit 41 places and conveys the waste tape member D on the conveying surface 49 (see FIGS. 4 to 6) which is the outer peripheral surface of the conveyor belt 55, and is configured to be able to transfer the waste tape member D to the waste tape conveying device 40 or the waste tape recovery unit 16 adjacent to the waste tape member D in the conveying direction C. Further, when the mounting device 15 constitutes a mounting line, the waste tape conveying unit 41 can transfer the waste tape member D to the adjacent waste tape conveying device 40. As shown in FIG. 3, the waste tape conveying unit 41 is configured such that the ends of adjacent conveyor devices overlap vertically. Thereby, the waste tape conveying unit 41 can smoothly transfer the waste tape member D to the adjacent waste tape conveying unit 41 and can suppress the dropping of the waste tape member D during the transfer.
[0018] The waste tape conveyance unit 41 has convex portions 55a on the lower surface side of the conveyance surface 49. In the present embodiment, the waste tape conveyance unit 41 has a plurality of convex portions 55a. In the present embodiment, the conveyor belt 55 itself does not have the convex portions 55a, but the conveyance surface 49, which is the outer peripheral surface of the conveyor belt 55, is configured to have the convex portions 55a by being deformed by the conveyance roller 52. Specifically, the conveyance roller 52 has pressing convex portions 52a on its outer peripheral surface, and the conveyance surface 49 is deformed by the pressing convex portions 52a pressing the inner peripheral surface of the conveyor belt 55 (see FIG. 6), so that the conveyance surface 49 has the convex portions 55a. Therefore, the convex portions 55a are present on the outer peripheral surface side of the portion where the conveyor belt 55 and the conveyance roller 52 are in contact, that is, on the folded-back portion of the downstream end of the conveyance surface 49 in the conveyance direction C. Accordingly, in the present embodiment, not only on the lower surface side of the folded-back portion of the conveyance surface 49 (the lower side than the horizontal line E passing through the central axis of the conveyance roller 52 shown in FIG. 6 in the folded-back portion), but also on the upper surface side of the folded-back portion of the conveyance surface 49 (the upper side than the horizontal line E passing through the central axis of the conveyance roller 52 shown in FIG. 6 in the folded-back portion), the convex portions 55a are present. Further, when the conveyor belt 55 rotates by the conveyance roller 51 and the conveyance roller 52, focusing on a certain region of the conveyor belt 55, when that region moves along the conveyance direction C and comes into contact with the conveyance roller 52, the convex portions 55a are temporarily formed, and before coming into contact with the conveyance roller 52 or after passing through the conveyance roller 52, the convex portions 55a do not exist in that region (that region returns to its original shape).
[0019] The conveying roller 52 has a plurality of pressing convex portions 52a, and the plurality of pressing convex portions 52a are arranged at a predetermined interval from each other. More specifically, the plurality of pressing convex portions 52a are arranged in a staggered pattern. Accordingly, the plurality of convex portions 55a are formed in a staggered pattern corresponding to the arrangement of the plurality of pressing convex portions 52a. In the present embodiment, as shown in FIG. 4, the plurality of convex portions 55a are arranged such that a row in which three convex portions 55a are aligned along the width direction of the conveyor belt 55 and a row in which four convex portions 55a are aligned along the width direction of the conveyor belt 55 alternately exist along the conveying surface 49, whereby the plurality of convex portions 55a are arranged in a staggered pattern.
[0020] The conveyor belt 55 is made of a flexible material that is deformed by the pressing convex portion 52a to form the convex portion 55a, and is composed of a resin such as rubber, for example. The pressing convex portion 52a is made of a material that is at least harder than the conveyor belt 55 so as to be able to deform the conveyor belt 55, and is composed of a metal or the like, for example. In the present embodiment, the pressing convex portion 52a has a shape obtained by cutting out a part of a sphere, and the surface is entirely a curved surface. Further, corresponding to the shape of the pressing convex portion 52a, the convex portion 55a is formed in a substantially circular shape when viewed from a direction perpendicular to the conveying surface 49. However, the pressing convex portion 52a (and the convex portion 55a) may have any shape, and for example, the pressing convex portion 52a may be cylindrical. Also, in the present embodiment, the pressing convex portion 52a is a member separate from the roller body of the conveying roller 52 and is adhered to the outer peripheral surface of the roller body. However, the present invention is not limited to this, and the pressing convex portion 52a may be integrally formed with the roller body of the conveying roller 52.
[0021] The air blowing unit 42 removes the waste tape member D adhering to the conveying surface 49 of the waste tape conveying unit 41 by blowing air. This air blowing unit 42 is fixed below the vicinity of the removal plate 45 in contact with the conveying surface 49 on the lower surface side. Also, the air blowing unit 42 is fixed behind the prevention plate 46 in contact with the conveying surface 49 of the adjacent waste tape conveying unit 41. That is, when the waste tape conveying device 40 constitutes the mounting line, the air blowing unit 42 is provided at a position between the waste tape conveying unit 41 and the adjacent waste tape conveying unit 41 or the waste tape recovery unit 16 disposed below this waste tape conveying unit 41. Further, the air blowing unit 42 is provided between the removal plate 45 and the prevention plate 46. This air blowing unit 42 is composed of a circulation pipe 43, an air blowing port 44, and a gas supply device (not shown). The circulation pipe 43 is disposed on the lower surface side of the conveying surface 49 of the waste tape conveying unit 41, is formed in a direction orthogonal to the conveying direction C, and allows gas to flow through. The gas to be circulated includes, for example, air. The air blowing port 44 is an opening formed in the circulation pipe 43 facing the conveying surface 49 of the waste tape conveying unit 41, and a plurality of them are formed along the circulation pipe 43 over the entire width direction of the conveying surface 49. The gas supply device is a device that compresses and supplies gas, such as an air compressor. This gas supply device also supplies gas to various parts (such as an air cylinder) in the housing of the mounting device 15.
[0022] The air blowing unit 42 is configured to blow gas in the blowing direction B shown in FIGS. 4 to 6 by adjusting the position of the flow pipe 43 and the orientation of the opening of the air outlet 44. The blowing direction B is a direction along the conveying surface 49, and in this embodiment, it is a direction along the conveying direction C (a direction from the upstream side to the downstream side of the conveying direction C). Note that the "direction along the conveying surface 49" is not limited to the case where it is parallel to the conveying surface 49, and it may be inclined with respect to the conveying surface 49. The same applies to the "direction along the conveying direction C". The inclination angle may be less than 90°, and may be 60° or less, 45° or less, or 30° or less. The inclination angle can be determined in advance by experiments or analysis as an angle at which the waste tape member D attached to the conveying surface 49 by the gas from the air outlet 44 can be peeled off. Further, the blowing direction B is adjusted to blow gas along the conveying surface 49 with respect to the region having the convex portion 55a on the lower surface side of the conveying surface 49 (in this embodiment, the lower surface side of the folded portion of the conveying surface 49). More specifically, as shown in FIG. 6, the blowing direction B is adjusted to blow gas along the conveying surface 49 with respect to the lower end portion of the folded portion of the conveying surface 49 (the region immediately before the contact between the conveyor belt 55 and the conveying roller 52 is separated).
[0023] Note that the air blowing direction B can be defined as the direction along the central axis of the region F (i.e., the region located in front of the air outlet 44) that is virtually extended from the inner peripheral surface of the air outlet 44 toward the conveying surface 49. It is preferable that the position of the circulation pipe 43, the orientation of the opening of the air outlet 44, etc. are adjusted such that at least a part of this region F overlaps with the region having the convex portion 55a on the lower surface side of the conveying surface 49 (in this embodiment, the lower end portion of the folded portion of the conveying surface 49). Thereby, the air blowing unit 42 can more reliably blow gas against the region having the convex portion 55a on the lower surface side of the conveying surface 49 (in this embodiment, the lower end portion of the folded portion of the conveying surface 49). Actually, the gas blown from the air outlet 44 spreads and flows outside this region F. Therefore, even when the region F and the region having the convex portion 55a on the lower surface side of the conveying surface 49 do not overlap, the position of the circulation pipe 43, the orientation of the opening of the air outlet 44, etc. may be adjusted so that the air blowing unit 42 can blow gas against the region having the convex portion 55a on the lower surface side of the conveying surface 49.
[0024] The removal plate 45 is disposed on the lower surface side of the conveying surface 49 on the downstream side in the conveying direction C of the waste tape conveying unit 41, and is a member that contacts the conveying surface 49 and removes the waste tape member D. The removal plate 45 is fixed to a fixing member 45a joined along the circulation pipe 43 on the upper side of the circulation 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 portion in the conveying direction C of the adjacent waste tape conveying unit 41, and is a member that contacts the conveying surface 49 and prevents the entry of the waste tape member D. The prevention plate 46 is fixed to a fixing member 46a joined along the circulation pipe 43 on the lower side of the circulation pipe 43. The prevention plate 46 is formed of a flexible member such as rubber or resin. The air blowing unit 42 is joined via the removal plate 45 and the fixing member 45a, and is also joined via the prevention plate 46 and the fixing member 46a.
[0025] Note that, as shown in FIGS. 4 to 6, the air blowing unit 42 is configured to blow gas against a region closer to the downstream end portion in the conveying direction C than the removal plate 45.
[0026] The drive unit 47 is a motor that is connected to the drive shaft of the conveyor of the waste tape conveyance unit 41 and rotationally drives the same. The drive unit 47 transmits a driving force to at least one of the conveyance rollers 51 and 52 via the drive shaft to rotate the conveyor belt 55. The control unit 48 is a controller that controls the entire waste tape conveyance device 40. The control unit 48 outputs a drive signal to the drive unit 47. Further, the control unit 48 communicates with the control unit 48 of an adjacent waste tape conveyance device 40 via a communication port (not shown).
[0027] Next, the operation of the mounting system 10 of the present embodiment configured in this way will be described. First, the process of the mounting device 15 mounting the component P on the substrate 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 substrate processing unit 22 to carry in and fix the substrate S. Next, based on the mounting condition information, the CPU 37 causes the component P to be collected from the feeder 24 mounted on the component supply unit 23 to the mounting head 32, and performs a process of arranging the collected component P at a predetermined position on the substrate S. When the component P has been arranged on the substrate S, the CPU 37 causes the substrate S to be discharged to the substrate processing unit 22, and as described above, repeats the process of carrying in the next substrate S to the substrate processing unit 22 and mounting the component P on the substrate S. Further, during this mounting process, the CPU 37 causes the waste tape discharge unit 26 to cut the tape member T and sends the generated waste tape member D to the waste tape conveyance device 40.
[0028] Next, the process of carrying 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 conveyance unit 41, and conveys the waste tape member D in the conveyance direction C. Further, the control unit 48 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 conveyance surface 49 of the waste tape conveyance unit 41. The waste tape member D sent from the waste tape discharge unit 26 is placed on the conveyance surface 49 of the waste tape conveyance unit 41 and conveyed in the conveyance direction C. For example, among the waste tape members D, there are not only resin tapes in which cavities for accommodating the parts P are formed, but also films that are easily charged with static electricity. Therefore, even if the waste tape conveyance unit 41 employs a conductive conveyor belt, films and the like may stick to the conveyance surface 49. And the waste tape member D such as a film stuck to the conveyance surface 49 may not fall from the conveyance surface 49 only when it reaches the lower surface side of the folded portion of the conveyance surface 49. At this time, in the waste tape conveyance unit 41 of the present embodiment, since the convex portion 55a exists at the folded portion of the conveyance surface 49, a gap is likely to be formed between the waste tape member D and the conveyance surface 49 by the convex portion 55a, and the contact area between the waste tape member D and the conveyance surface 49 can be reduced. Therefore, in this waste tape conveyance unit 41, the waste tape member D can be made to fall easily on the lower surface side of the conveyance surface 49 (in the present embodiment, particularly the lower surface side of the folded portion of the conveyance surface 49). Further, since the blower unit 42 blows gas along the conveyance surface 49 against the region having the convex portion 55a on the lower surface side of the conveyance surface 49 of the waste tape conveyance unit 41, gas easily enters the gap between the waste tape member D and the conveyance surface 49 generated by the convex portion 55a. Therefore, the waste tape member D becomes more likely to fall.
[0029] Also, in the waste tape conveyance unit 41, a removal plate 45 is used, and the waste tape member D can also be peeled off from the conveyance surface 49 by the removal plate 45. However, the waste tape member D was sometimes pinched between the removal plate 45 and the conveyor belt 55. In contrast, in the waste tape conveyance unit 41 of the present embodiment, the removal plate 45 is in contact with the upstream side in the conveyance direction than the region where the convex portion 55a is formed by the conveyance roller 52 on the lower surface side of the conveyance surface 49. Therefore, due to the presence of the convex portion 55a, the waste tape member D is likely to fall before reaching the removal plate 45, so that the waste tape member D reaching the removal plate 45 can be reduced, and the waste tape member D can be prevented from being pinched between the removal plate 45 and the conveyor belt 55. Further, the air blowing unit 42 is configured to blow gas against a region closer to the downstream end in the conveyance direction C than the removal plate 45. Therefore, before the waste tape member D reaches the removal plate 45, the waste tape member D is likely to fall due to the gas blown from the air blowing unit 42. This can also reduce the waste tape member D reaching the removal plate 45 and prevent the waste tape member D from being pinched between the removal plate 45 and the conveyor belt 55.
[0030] Also, in the waste tape conveyance unit 41, since there is no gap due to the prevention plate 46, it is possible to prevent the waste tape member D from entering the gap between the waste tape conveyance units 41.
[0031] Here, the correspondence between the components of the present embodiment and the components of the present disclosure will be clarified. The waste tape conveyance unit 41 of the present embodiment corresponds to the waste tape conveyance unit of the present disclosure, the conveyor belt 55 corresponds to the conveyor belt, the conveyance surface 49 corresponds to the conveyance surface, and the convex portion 55a corresponds to the convex portion. Further, the conveyance roller 52 corresponds to the convex portion forming member and the conveyor conveyance roller, the pressing convex portion 52a corresponds to the concave pressing convex portion, the air blowing unit 42 corresponds to the air blowing unit, and the removal plate 45 corresponds to the removal plate. Also, 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.
[0032] The waste tape conveying device 40 of the present embodiment described above places the cut waste tape member D after the component P is taken on the conveying surface 49 of the conveyor belt 55 and conveys it, and is configured to be able to transfer the waste tape member D to the waste tape conveying device 40 or the waste tape recovery unit 16 adjacent to the conveying direction C of the waste tape member D. And the waste tape conveying unit 41 has a convex portion 55a on the lower surface side of the conveying surface 49. Thereby, in this waste tape conveying device 40, the contact area between the waste tape member D and the conveying surface 49 can be reduced by the convex portion 55a. Therefore, in this waste tape conveying device 40, it is possible to make the waste tape member D more likely to fall on the lower surface side of the conveying surface 49.
[0033] Further, the waste tape conveying device 40 is provided inside the conveyor belt 55 and includes a conveying roller 52 that functions as a convex portion forming member that deforms the conveying surface 49 so that the lower surface side of the conveying surface 49 of the conveyor belt 55 has a convex portion 55a by pressing the inner peripheral surface of the conveyor belt 55. Therefore, in this waste tape conveying device 40, the convex portion 55a can be formed on the lower surface side of the conveying surface 49 of the conveyor belt 55 by this conveying roller 52.
[0034] Furthermore, in the waste tape conveying device 40, the convex portion forming member is a conveyor conveying roller 52 having a pressing convex portion 52a on the outer peripheral surface and disposed inside the conveyor belt 55 at the downstream end in the conveying direction C. By pressing the inner peripheral surface of the conveyor belt 55 with the pressing convex portion 52a, the folded portion is deformed so that the lower surface side of the folded portion of the conveying surface 49 has a convex portion 55a. Therefore, in this waste tape conveying device 40, the conveyor conveying roller 52 at the downstream end can also serve as a convex portion forming member.
[0035] Furthermore, the waste tape conveying device 40 includes a blower unit 42 that blows gas along the conveying surface 49 against a region having the convex portion 55a on the lower surface side of the conveying surface 49 of the waste tape conveying unit 41. Therefore, in this waste tape conveying device 40, gas is blown along the conveying surface 49 against a region where the contact area between the waste tape member D and the conveying surface 49 is reduced by the convex portion 55a, that is, a region where a part of the waste tape member D is likely to float from the conveying surface 49, so that the waste tape member D is more likely to fall.
[0036] And the waste tape conveying device 40 includes a removal plate 45 that abuts against the lower surface side of the conveying surface 49 of the waste tape conveying unit 41 and removes the waste tape member D. Therefore, in this waste tape conveying device 40, not only the convex portion 55a but also the removal plate 45 can make the waste tape member D more likely to fall.
[0037] Also, the mounting device 15 includes the above-described waste tape conveying device 40, a component supply unit 23 that supplies components P from a tape member T that houses a plurality of components P, and a mounting unit 30 that picks up the supplied components P. In this mounting device 15, since the above-described waste tape conveying device 40 is provided, the waste tape member D can be made to fall more easily on the lower surface side of the conveying surface 49.
[0038] Furthermore, the mounting device 15 is used in a mounting system 10 that constitutes a mounting line by arranging a plurality of units, and the waste tape conveying unit 41 delivers the waste tape member D to a waste tape conveying device 40 or a waste tape recovery unit 16 adjacent to the waste tape member D in the conveying direction C when the mounting line is constituted. In this mounting device 15, on the mounting line, the waste tape member D can be made to fall more easily on the lower surface side of the conveying surface 49. Thereby, the waste tape member D can be conveyed more reliably to the waste tape conveying device 40 or the waste tape recovery unit 16 adjacent in the conveying direction C.
[0039] It should be noted that the present disclosure is not limited to the above-described embodiments at all, and it goes without saying that the present disclosure can be implemented in various modes as long as it belongs to the technical scope of the present disclosure.
[0040] For example, in the above-described embodiment, the plurality of convex portions 55a (and the pressing convex portion 52a) are arranged in a staggered pattern, but the present invention is not limited thereto. For example, as shown in FIG. 7, the plurality of convex portions 55a (and the pressing convex portion 52a) may be arranged in a grid pattern. In FIG. 7, a plurality of columns in which four convex portions 55a are arranged along the width direction of the conveyor belt 55 exist along the conveying surface 49, so that the plurality of convex portions 55a are arranged in a grid pattern. Further, as long as the plurality of convex portions 55a (and the pressing convex portion 52a) are arranged at a predetermined interval from each other, the arrangement is not limited to a staggered pattern or a grid pattern. Further, in the case where the plurality of convex portions 55a (and the pressing convex portion 52a) are arranged at a predetermined interval from each other, the plurality of convex portions 55a may be arranged so as to include a column in which three or more convex portions 55a (and the pressing convex portion 52a) are arranged along the width direction of the conveyor belt 55. Furthermore, the plurality of convex portions 55a (and the pressing convex portion 52a) are not limited to being arranged at a predetermined interval from each other, and may be arranged in any manner, such as being randomly arranged.
[0041] In the above-described embodiment, the conveying roller 52 having the pressing convex portion 52a also serves as a convex portion forming member, but the present invention is not limited thereto, and the waste tape conveying device 40 may include a convex portion forming member as a member separate from the conveying roller 52. For example, a convex portion forming member that presses and deforms the inner peripheral surface of the conveyor belt 55 may be arranged upstream of the conveying roller 52 in the conveying direction C and downstream of the contact portion between the conveying surface 49 and the removing plate 45 in the conveying direction C. The convex portion forming member disposed separately from the conveying roller 52 may be, for example, a roller that contacts only the lower side of the inner peripheral surface of the conveyor belt 55 and rotates as the conveyor belt 55 rotates, or a plate-like member that contacts only the lower side of the inner peripheral surface of the conveyor belt 55 and slides on the conveyor belt 55.
[0042] In the above-described embodiment, the conveyance roller 52 presses the inner peripheral surface of the conveyor belt 55 to deform the conveyance surface 49, so that the conveyance surface 49 has the convex portion 55a. However, the present invention is not limited to this. For example, as shown in FIG. 8, the conveyor belt 55 may be configured to have a shape with the convex portion 55a. In FIG. 8, the conveyance roller 52 does not include the pressing convex portion 52a, and the conveyor belt 55 itself has a plurality of convex portions 55a arranged in a staggered manner. In this way, since the conveyor belt 55 itself has a shape with the convex portion 55a, the convex portion 55a orbits as the conveyor belt 55 rotates. Therefore, inevitably, the convex portion 66a exists on the lower surface side of the conveyance surface 49. Also in the waste tape conveyance device 40 configured in this way, similar to the above-described embodiment, it is possible to facilitate the dropping of the waste tape member D on the lower surface side of the conveyance surface 49. However, when the conveyor belt 55 itself has a shape with the convex portion 55a, the convex portion 55a needs to pass through the contact portion between the conveyance surface 49 and the removal plate 45. At this time, there is a possibility that the convex portion 55a and the removal plate 45 interfere with each other, such as the convex portion 55a being caught by the removal plate 45. Therefore, compared with the case where the conveyor belt 55 itself has a shape with the convex portion 55a, it is preferable to configure the waste tape conveyance device 40 such that the convex portion 55a exists only in a partial region of the conveyance surface 49 that does not interfere with the removal plate 45 by using a convex portion forming member as in the above-described embodiment. In this way, the waste tape conveyance device 40 can be configured such that the convex portion 55a does not pass through the contact portion between the conveyance surface 49 and the removal plate 45.
[0043] In the above-described embodiment, the waste tape conveying unit 41 has the convex portion 55a on the lower surface side of the conveying surface 49, but it may have a concave portion instead of the convex portion 55a. For example, as shown in FIG. 9, the conveyor belt 55 itself may be configured in a shape having a plurality of concave portions 55b. Also in the waste tape conveying device 40 configured in this way, since the contact area between the waste tape member D and the conveying surface 49 can be reduced by the concave portions 55b, the waste tape member D can be easily dropped on the lower surface side of the conveying surface 49 in the same manner as in the above-described embodiment. Further, when the conveyor belt 55 has the concave portions 55b, the concave portions 55b do not interfere with the removal plate 45 at the contact portion of the conveying surface 49 with the removal plate 45. Note that the waste tape conveying unit 41 only needs to have a convex portion and / or a concave portion on the lower surface side of the conveying surface 49. For example, the conveyor belt 55 itself may be configured in a shape having a plurality of convex portions 55a and a plurality of concave portions 55b. Alternatively, the waste tape conveying unit 41 may have the convex portion 55a formed on the conveying surface 49 by the conveying roller 52 as in the above-described embodiment, and the conveyor belt 55 itself may be configured in a shape having the concave portions 55b. Also, the arrangement of the concave portions 55b can adopt various modes similar to the arrangement of the convex portions 55a described above.
[0044] In the above-described embodiment, the convex portions 55a (and the pressing convex portions 52a) were formed in a substantially circular shape when viewed from a direction perpendicular to the conveying surface 49, but it is not particularly limited thereto. For example, as shown in FIG. 10, the convex portions 55a (and the pressing convex portions 52a) may have an oblong shape having a longitudinal direction along the width direction of the conveyor belt 55 when viewed from a direction perpendicular to the conveying surface 49. Alternatively, each of the plurality of pressing convex portions 52a may have a ring shape that goes around the outer peripheral surface of the conveying roller 52, and the corresponding convex portion 55a may be formed in an arc shape of a semi-circle formed at the folded portion of the conveying surface 49. Also, the number of the convex portions 55a (and the pressing convex portions 52a) is not limited to a plurality. For example, it may be one convex portion 55a (and the pressing convex portion 52a) provided so as to meander on the conveying surface 49 (and the outer peripheral surface of the conveying roller 52). Regarding the above-described concave portions, any of these modes of the convex portions 55a may be adopted.
[0045] In the above-described embodiment, the blower unit 42 blows gas in the direction along the conveyance direction C against the region having the convex portion 55a on the lower surface side of the conveyance surface 49 of the waste tape conveyance unit 41. However, as described above, the gas may be blown not only in the direction along the conveyance direction C but also in the direction along the conveyance surface 49. For example, the gas may be blown in the direction along the conveyance surface 49 and perpendicular to the conveyance direction C (i.e., the width direction of the conveyor belt 55). In this case, for example, the blower unit 42 may be disposed outside the width direction of the conveyor belt 55, and the gas may be blown against the region having the convex portion 55a on the lower surface side of the conveyance surface 49 of the waste tape conveyance unit 41.
[0046] In the above-described embodiment, the blower unit 42 is disposed at a position between the waste tape conveyance unit 41 and an adjacent waste tape conveyance unit 41 or the waste tape collection unit 16. However, it may be considered that it is not particularly limited to the positional relationship with the adjacent devices.
[0047] In the above-described embodiment, the blower unit 42 includes the flow pipe 43 and the air outlet 44. However, as long as it can blow air to the lower surface side of the conveyance surface 49, it is not particularly limited to this structure. For example, the blower unit 42 may be constituted by a blower fan.
[0048] In the above-described embodiment, the waste tape conveyance device 40 has been described as including the blower unit 42 and the removal plate 45. However, it is not particularly limited thereto, and it may not include at least one of the blower unit 42 and the removal plate 45.
[0049] In the above-described embodiment, the waste tape conveyance device 40 has been described as including the prevention plate 46. However, it may not include the prevention plate 46.
[0050] In the above-described embodiment, the blower unit 42 has been described as being joined to the removal plate 45 and the prevention plate 46 via the fixing members 45a and 46a. However, it is not particularly limited thereto, and the blower unit 42 may not be joined to the removal plate 45 and the prevention plate 46.
[0051] In the above-described embodiment, the mounting apparatus 15 including the waste tape conveyance device 40 and the mounting system 10 having the mounting apparatus 15 including the waste tape conveyance device 40 have been described. However, the present invention is not particularly limited thereto, and the waste tape conveyance device 40 may be used as well.
