Description

[Technical Field]

[0001] The present specification relates to a used tape processing apparatus that processes used tape, which is a used portion of a carrier tape used to supply parts. [Background technology]

[0002] Technologies for mass-producing board products by performing substrate-related operations on boards on which circuit patterns are formed are becoming widespread. A typical example of a substrate-related operation machine for performing substrate-related operations is a component placement machine for performing component placement operations. Many component placement machines are equipped with a tape feeder that supplies components using a carrier tape that stores multiple components. The tape feeder pulls out the carrier tape wound on a reel and feeds it to a predetermined supply position to supply the components. Once the carrier tape (used tape) has been used after the components have been removed from it at the supply position, it is ejected outside the tape feeder and disposed of. When disposing of used tape, it is necessary to prevent jamming (feeding failure) by taking into account the tendency of the tape to curl when wound on a reel. Examples of technologies related to this type of used tape disposal are disclosed in Patent Documents 1 and 2.

[0003] Patent Document 1 discloses a guide unit 70 having a fixed guide plate 71 that guides the component supply tape 22 toward the fixed cutter 64, an auxiliary guide plate 72 that forms a guide channel between the fixed guide plate 71, and an elastic plate 73 that is divided into segments 75 for each component supply tape 22 and fixed to the lower end of the auxiliary guide plate 72, and presses the component supply tape 22 against the fixed guide plate 71 (see specification, page 9, line 12 to page 10, line 8, and Figures 4-6). According to this, the component supply tape is reliably guided between the fixed cutter and the movable cutter, differences in tape thickness are absorbed by the deflection of the elastic plate, and because the elastic plate is divided into segments for each tape, differences in thickness of adjacent tapes do not affect adhesion to the fixed guide plate.

[0004] Patent Document 2 also discloses a tape chute 40 in which a corrugated bottom surface 44 having recesses 44a that continue in the discharge direction of the empty tape 25 is provided on the inner lower surface of a gently sloping section 42, which is the surface that comes into contact with the empty tape 25 (see paragraph 0019, Figures 3-4). According to this, empty tape 25B, which has a strong tendency to move in a straight direction, such as embossed resin tape, enters the recesses 44a and moves forward, while empty tape 25A, which has a strong tendency to curl, such as paper tape, does not enter the recesses 44a and slides on the upper surfaces of the protrusions 44b and moves forward in a curved state, thereby eliminating machine trouble caused by interference between empty tapes (see paragraphs 0020-0021, Figures 4(b) and 7). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Utility Model Application Publication No. 04-036299 [Patent Document 2] Japanese Patent Application Laid-Open No. 2000-013093 Summary of the Invention [Problem to be solved by the invention]

[0006] In Patent Document 1, the component supply tape 22 is guided (introduced) at a position closer to the fixed cutter, but the leading edge of the component supply tape 22 that has passed the fixed cutter is not guided. As a result, there is a risk that the component supply tape 22 that has passed the fixed cutter will jam before being cut. For example, there is a risk that multiple component supply tapes 22 will interfere with each other and not proceed smoothly, resulting in poor cutting, or that the component supply tape 22 will get caught in the gap around the movable cutter and impede the operation of the movable cutter.

[0007] In contrast, Patent Document 2 does not include a cutter for cutting the tape, and instead guides the empty tape 25B, which tends to run straight, into the recess 44a in the tape chute 40, while allowing the empty tape 25A, which tends to curl, to advance in a curved state. Therefore, the risk of jamming due to mutual interference between the multiple empty tapes 25A advancing in a curved state is not eliminated. Furthermore, even if the wavy bottom surface 44 of Patent Document 2 is provided at a position past the fixed cutter of Patent Document 1, the risk of jamming is not eliminated.

[0008] Therefore, an object of the present specification is to provide a used tape processing device that reduces the risk of used tape jamming compared to the prior art. [Means for solving the problem]

[0009] This specification discloses a used tape processing device that includes a cutting mechanism having a fixed blade and a movable blade that moves toward and away from the fixed blade, and that cuts used tape, which is the used portion of a carrier tape that is discharged from a tape feeder that supplies components using a carrier tape that contains multiple components, and a slide cover that is integral with the movable blade and has a guide surface with a slit formed in the vertical direction that guides the movement of the used tape that passes between the fixed blade and the movable blade that is moving toward and away from the fixed blade.

[0010] This specification also discloses a component supplying device that includes the used tape processing device and the tape feeder. Furthermore, this specification discloses a component mounting machine that includes the used tape processing device, the tape feeder, and a dust box that collects tape pieces cut from the used tape by the cutting mechanism.

[0011] This specification discloses the technical idea of ​​changing "the used tape processing device according to claim 1" in claim 3 originally filed to "the used tape processing device according to claim 1 or 2," and the technical idea of ​​changing "the used tape processing device according to any one of claims 1-3" in claim 6 originally filed to "the tray feeder according to any one of claims 1-5." Furthermore, this specification discloses the technical idea of ​​changing "a component supplying device equipped with a used tape processing device according to any one of claims 1-3" in claim 7 originally filed to "a component supplying device equipped with a used tape processing device according to any one of claims 1-6," and the technical idea of ​​changing "a component placement machine equipped with a used tape processing device according to any one of claims 1-3" in claim 8 originally filed to "a component placement machine equipped with a used tape processing device according to any one of claims 1-6." [Effects of the Invention]

[0012] In the disclosed configuration, a sliding cover integral with the movable blade covers a structural gap around the movable blade, preventing used tape that has passed between the fixed blade and the movable blade from entering the gap. Furthermore, a slit formed on the guide surface of the sliding cover prevents the leading edge of the used tape from sliding sideways. Therefore, the disclosed configuration reduces the risk of used tape jamming compared to conventional techniques. [Brief explanation of the drawings]

[0014] 1. Overall configuration of component placement machine 9 The used tape processing device 1 of the embodiment is fixedly provided to the component mounting machine 9, or is provided to a component supply device 93 that is detachably mounted to the component mounting machine 9. First, the overall configuration of the component mounting machine 9 that fixedly includes the used tape processing device 1 of the embodiment will be described with reference to FIG. 1. The component mounting machine 9 performs a mounting operation to mount components on a board K. The horizontal direction from the left to the right of the page in FIG. 1 is the X-axis direction along which the board K is transported, the horizontal direction from the bottom (front) to the top (rear) of the page is the Y-axis direction, and the vertical direction is the Z-axis direction. The component mounting machine 9 is configured by assembling the used tape processing device 1, a board transport device 92, a component supply device 93, a component transfer device 94, a control device 96, and the like to a base 91.

[0015] The board transport device 92 is composed of a pair of guide rails 921, a pair of conveyor belts (not shown), and a clamping mechanism 922. The pair of guide rails 921 extend in the X-axis direction across the center of the upper surface of the base 91 and are attached to the base 91 parallel to each other. The pair of conveyor belts rotate along the guide rails 921 with two parallel sides of the board K placed on them, and transport the board K to a stopping position near the center of the base 91. The clamping mechanism 922 is disposed below the stopping position, and pushes up the board K and clamps it between the guide rails 921 to position it. After the component mounting operation by the component transfer device 94 is completed, the clamping mechanism 922 releases the board K, and the conveyor belts carry the board K out of the machine.

[0016] The component supply device 93 is disposed on the upper surface of the base 91 at the front in the Y-axis direction. The component supply device 93 is composed of a pallet table 931, multiple tape feeders (8A, 8B), and the like. The pallet table 931 is formed in a roughly rectangular shape in a plan view, and may be formed in the shape of a dolly with casters for movement. The pallet table 931 has multiple groove-shaped slots 932 on its upper surface that extend parallel to and spaced apart from each other in the Y-axis direction. The multiple slots 932 are provided at a pitch of 10 mm, but the pitch may be different from 10 mm. Multiple tape feeders are installed side by side in the multiple slots 932.

[0017] A tape feeder supplies components using a carrier tape that holds multiple components. There are several types of tape feeders. For example, there are semi-peeling types in which the cover tape is partially peeled off from the base tape that makes up the carrier tape before the components are supplied, and the base tape and cover tape are processed together, and full-peeling types in which the cover tape is completely peeled off from the base tape before the components are supplied, and the base tape and cover tape are processed separately. There are also reel-integrated types in which the reel around which the carrier tape is wound is held integrally, and separate-reel types in which the reel is placed separately from the reel holding device. Furthermore, tape feeders can generally be used with any type of carrier tape (e.g., embossed resin tape, paper tape, etc.).

[0018] Here, multiple tape width dimensions are standardized for carrier tapes to accommodate various sizes of components to be housed. Multiple models of tape feeders are used depending on the tape width dimensions of the carrier tape. In this embodiment, two models of tape feeders (8A, 8B) that are semi-peeling, integrated with a reel, and use paper tapes with different tape width dimensions will be described as examples.

[0019] The standard tape feeder 8A uses a carrier tape with a tape width dimension of 4 mm or 8 mm. This tape feeder 8A is installed in one slot 932. Therefore, the arrangement pitch PF of multiple tape feeders 8A is 10 mm, which is equal to the pitch of the slots 932. The large tape feeder 8B uses a carrier tape with a tape width dimension exceeding 8 mm. The large tape feeder 8B is installed across multiple slots 932. The used portion of the carrier tape discharged from the tape feeders (8A, 8B) is called used tape TP (see Figure 3).

[0020] The component transfer device 94 is composed of a Y-axis movable body 941, an X-axis movable body 942, a mounting head 943, a nozzle tool 944, multiple suction nozzles 95, a board camera 946, and a component camera 947. The Y-axis movable body 941 and the X-axis movable body 942 constitute an XY drive mechanism that moves the mounting head 943 horizontally in two directions. A rotationally symmetric nozzle tool 944 is provided below the mounting head 943. The nozzle tool 944 is provided with multiple (20 in the example of FIG. 1) replaceable suction nozzles 95. The suction nozzles 95 perform a mounting operation by suctioning components supplied from tape feeders (8A, 8B) and mounting them on the board K at the stop position. Note that the mounting head 943 may have multiple suction nozzles 95 arranged in a line or in a grid pattern. Furthermore, the mounting head 943 may be provided with a component mounting tool other than the suction nozzles 95, such as a chuck-type mounting tool that grips components.

[0021] The board camera 946 is mounted facing downward on the X-axis movable body 942 alongside the mounting head 943. The board camera 946 captures an image of a position mark attached to the board K from above to accurately determine the stopping position of the board K. The component camera 947 is mounted facing upward between the board transport device 92 and the component supply device 93. The component camera 947 captures an image of the component held by the suction nozzle 95 from below while the mounting head 943 is moving from the component supply device 93 to the board K, and recognizes the component. This allows the correctness of the component type to be determined, and the position and orientation of the component relative to the suction nozzle 95 to be detected and reflected in the mounting operation. Examples of the board camera 946 and the component camera 947 include digital imaging devices having imaging elements such as CCDs (Charge Coupled Devices) and CMOSs ​​(Complementary Metal Oxide Semiconductors).

[0022] The control device 96 is mounted on the base 91, and its location is not particularly limited. The control device 96 is configured using a computer device. The control device 96 may also be configured with multiple CPUs distributed within the device and connected for communication. The control device 96 controls the board transport device 92, component supply device 93, component transfer device 94, and used tape processing device 1 based on work data created for each type of board product (board K), to proceed with the component mounting work. The work data includes material information regarding the type and shape of the board K and components, as well as coordinate information for the component pickup and mounting positions.

[0023] The used tape processing device 1 is provided at a position between the component supply device 93 and the component camera 947 in the Y-axis direction. The used tape processing device 1 has a length in the X-axis direction that is approximately the same as that of the pallet table 931, and is provided in common for multiple tape feeders (8A, 8B) arranged side by side. The used tape processing device 1 extends downward from behind the tape feeders (8A, 8B) in the Z-axis direction. The used tape processing device 1 cuts and processes the used tape TP.

[0024] 2. Detailed configuration of used tape processing device 1 Next, the detailed configuration of the used tape processing device 1 will be described with reference to Figures 2 to 5. As shown in Figure 2, the used tape processing device 1 is composed of a duct 2, a cutting mechanism 3, a chute 4, etc., and is equipped with a dust box 5. In the used tape processing device 1, the used tape TP discharged from the tape feeders (8A, 8B) is guided by the duct 2 and cut by the cutting mechanism 3, and the cut pieces of tape TC (see Figure 6) are guided to fall into the dust box 5 by the chute 4.

[0025] As shown in Figure 2, the duct 2 is formed long in the X-axis direction and has a cylindrical shape with a rectangular cross section that is bent in the Y-axis and Z-axis directions. More specifically, the duct 2 starts from the tape discharge position at the top of the rear end of the tape feeder (8A, 8B) and extends horizontally rearward, bending partway along the way and gradually changing direction downward. Furthermore, the duct 2 extends in a direction slightly tilted rearward from the Z-axis direction (vertical direction) and faces the cutting mechanism 3 located below. The duct 2 bends and lowers the used tape TP that is discharged horizontally rearward from the tape discharge position of the tape feeder (8A, 8B), and guides it to the cutting mechanism 3.

[0026] The cutting mechanism 3 is composed of a fixed blade 31, a movable blade 32, a drive mechanism 33, and the like. The fixed blade 31 and the movable blade 32 are common to multiple tape feeders (8A, 8B) and are formed long in the X-axis direction. At least one of the fixed blade 31 and the movable blade 32 may be divided partway along the X-axis direction to form multiple blades. As shown in FIG. 3, the fixed blade 31 is disposed on the lower rear side of the duct 2. The cutting edge of the fixed blade 31 faces forward.

[0027] The movable blade 32 is positioned forward of the fixed blade 31. The cutting edge of the movable blade 32 faces rearward and is positioned lower than the cutting edge of the fixed blade 31. The movable blade 32 is movable in the horizontal forward and backward directions, and moves forward and backward relative to the fixed blade 31. In other words, the movable blade 32 moves forward and backward between a retracted position (see FIG. 3) separated from the fixed blade 31 and an advanced position (see FIG. 6) below the fixed blade 31. In this way, the cutting mechanism 3 shears (cuts) the used tape TP by the intersection of the cutting edges of the fixed blade 31 and the movable blade 32, generating tape cut pieces TC.

[0028] The forward and backward movement of the movable blade 32 is driven by a drive mechanism 33. The drive mechanism 33 is disposed below the pallet table 931 and is controlled by a control device 96. The control device 96 operates the drive mechanism 33 when a predetermined cutting condition is met. For example, the predetermined cutting condition may be a condition in which the tape feeders (8A, 8B) have supplied a predetermined number of parts, in other words, a condition in which the used tape TP has become longer by a predetermined amount. If the operation frequencies of the multiple tape feeders (8A, 8B) differ, the satisfaction of the cutting condition is determined based on the tape feeder (8A, 8B) with the highest operation frequency.

[0029] The drive mechanism 33 is preferably an air drive mechanism that uses an air supply source and an air cylinder. This allows the drive mechanism 33 and the suction nozzle 95 of the component transfer device 94 to share the air supply source. However, the drive mechanism 33 may have a dedicated drive source such as a motor or an electromagnetic solenoid. Note that if the movable blade 32 is configured to be divided into multiple pieces, the drive mechanism 33 may drive the multiple movable blades 32 individually.

[0030] The chute 4 is disposed below the cutting mechanism 3. The chute 4 guides the tape pieces TC cut by the cutting mechanism 3 as they fall and lead them into the dust box 5. The chute 4 is long in the X-axis direction and short in the Y-axis direction (front-rear direction), and is formed in the shape of a square tube with a rectangular horizontal cross section that opens at the top and bottom. The chute 4 consists of a front panel 41, two side panels 42, and a rear panel 43. The front panel 41 is located below the movable blade 32 and extends in a direction slightly tilted forward from the Z-axis direction. A gap G is provided between the front panel 41 and the movable blade 32 so as not to hinder the forward and backward movement of the movable blade 32. Alternatively, a gap G may be generated structurally even if the gap G is not intentionally provided.

[0031] The two side plates 42 are spaced apart by a distance greater than the X-axis dimension of the fixed blade 31 and the movable blade 32. The rear plate 43 is located rearward of the fixed blade 31 and extends downward below the fixed blade 31. The rear plate 43 has a rear upper surface 44 that stands upright in the Z-axis direction and a rear slope 45 that is bent rearward from the lower end of the rear upper surface 44. The rear slope 45 increases the opening area of ​​the lower part of the chute 4. This increases the opening and internal volume of the upper part of the dust box 5, thereby increasing the collection capacity of the tape fragments TC. A sheet 46 is attached to the lower opening of the chute 4 to close the gap between the dust box 5 and the chute 4. An anti-static material can be attached to the inner surface of the chute 4 to prevent static electricity from adhering to the tape fragments TC.

[0032] The dust box 5 is movably disposed below the chute 4. The dust box 5 collects the tape fragments TC that drop from the chute 4. The dust box 5 is formed in a box shape with an opening at the top, and is disposed opposite the opening at the bottom of the chute 4. The dust box 5 is removed by an operator, and the collected tape fragments TC are disposed of. The dust box 5 may have a sensor that detects the height or volume of the top of the collected tape fragments TC, making it possible to estimate the time for disposal and to provide notification or advance notice.

[0033] 3. Slide cover 6 and slit 63 In the above-described configuration, there is a risk that the used tape TP passing between the fixed blade 31 and the movable blade 32 moving back and forth may enter the gap G between the movable blade 32 and the chute 4. Here, it is common for the used tape TP to have a tendency to curl due to the carrier tape being wound on a reel. In this case, the used tape TP tends to move in the direction of the tendency to curl rather than descend straight, increasing the risk of the used tape TP entering the gap G. If the used tape TP were to enter the gap G, it would hinder the moving back and forth movement of the movable blade 32, causing a problem. To address this problem, a slide cover 6 is provided in this embodiment.

[0034] As shown in FIG. 3 , the sliding cover 6 has a height dimension similar to that of the front plate 41 of the chute 4, but a dimension in the X-axis direction slightly smaller than that of the front plate 41, and its upper portion is bent horizontally forward. The sliding cover 6 is attached to the lower side of the movable blade 32 using fasteners 61 (e.g., multiple screws) so that the horizontal portion of its upper portion is in close contact with the underside of the movable blade 32. In other words, the sliding cover 6 is provided integrally with the movable blade 32. The sliding cover 6 extends in a direction slightly tilted forward from the Z-axis direction within the chute 4 and is disposed parallel to the front plate 41. When the movable blade 32 is in the retracted position, the sliding cover 6 is in contact with or located very close to the front plate 41. The sliding cover 6 moves integrally with the movable blade 32 to advance and retreat within the chute 4.

[0035] The leading edge of the used tape TP may come into contact with the rear surface of the slide cover 6 as it descends. Therefore, the rear surface of the slide cover 6 serves as a guide surface 62 that guides the movement of the used tape TP. Furthermore, the guide surface 62 may come into contact with the cut piece of tape TC. Therefore, the guide surface 62 also serves as a guide surface that guides the falling piece of tape TC.

[0036] In a configuration provided with the sliding cover 6, as shown in Fig. 4, there is a risk that the leading edge of the used tape TP will slide sideways in the left-right direction due to its tendency to curl. In Fig. 4, the leading edge of the used tape TP that has descended straight is indicated by a dashed line, and the leading edge of the used tape TP that has slid sideways due to its tendency to curl is indicated by a solid line. This does not eliminate the risk that multiple used tapes TP discharged from each of the multiple tape feeders (8A, 8B) will interfere with each other and cause jamming (feeding failure). As a countermeasure to this risk, in this embodiment, multiple slits 63 are formed in the guide surface 62 of the sliding cover 6.

[0037] 5, the multiple slits 63 are formed parallel to one another and extend in the vertical direction, which corresponds to the movement direction of the used tape TP. The formation pitch PS of the multiple slits 63 is finer than the arrangement pitch PF of the multiple tape feeders 8A. In this embodiment, the arrangement pitch PF of the tape feeders 8A is 10 mm, while the formation pitch PS of the slits 63 is 6 mm. Furthermore, the slit width WS of the slits 63 is 3.5 mm, and the remaining width WZ of the remaining portion 64 where no slits 63 are formed is 2.5 mm.

[0038] The slit 63 has a rectangular cross-sectional shape in a cross section intersecting the vertical direction. In this embodiment, the depth dimension of the slit 63 is not particularly limited, but the shape of the rectangular groove is important. That is, the slit 63 has edges at right angles to the remaining portion 64 on both sides in the width direction. The edges on both sides of the slit 63 in the width direction suppress lateral slippage of the used tape TP (described in detail below). On the other hand, the corrugated recesses 44a disclosed in Patent Document 2 cannot suppress lateral slippage, so the shape of the recesses 44a cannot be used for the slit 63. Note that the slit 63 may have edges at an acute angle to the remaining portion 64. That is, the slit 63 may have a cross-sectional shape of an isosceles trapezoid with a narrow groove entrance and a wide groove bottom.

[0039] The slide cover 6 with multiple slits 63 formed therein can be manufactured by cutting a commercially available processed steel plate. For example, the slide cover 6 can be manufactured using a stainless steel plate with pre-formed slits called "SUS304 GP." The above-described combination of forming pitch PS, slit width WS, and remaining width WZ is an example of a commercially available product. This allows for lower manufacturing costs compared to a manufacturing method in which the slits 63 are formed in-house in a plate slide cover 6.

[0040] 4. Operation, Function, and Effects of Used Tape Processing Device 1 Next, the operation, function, and effects of the used tape processing device 1 will be described, including the operation of the component mounting machine 9. The control device 96 of the component mounting machine 9 controls the component transfer device 94 to pick up components from the multiple tape feeders (8A, 8B) and mount them on the board. Each tape feeder (8A, 8B) pitch-feeds the carrier tape each time a component is picked up, so the used tape TP gradually becomes longer. At this time, the used tape TP is guided by the duct 2 toward the cutting mechanism 3. As the used tape TP becomes longer, it passes through the cutting mechanism 3 and its leading edge reaches the chute 4. The leading edge of the used tape TP floats within the chute 4 or abuts against the guide surface 62 of the slide cover 6. In either case, there is no risk of the used tape TP entering the gap G and obstructing the forward / backward movement of the movable blade 32.

[0041] Furthermore, the used tape TP that abuts against the guide surface 62 may tend to slide sideways in the left-right direction due to its tendency to curl. In this case, as shown in FIG. 5, the sliding of the used tape TP is suppressed. More specifically, when the used tape TP that abuts against the guide surface 62 attempts to slide sideways as indicated by arrow M1, the leading edge of the used tape TP may move sideways within the slit 63. However, the leading edge of the used tape TP is caught on the right-angled edge of the slit 63, preventing further sliding. Here, because the formation pitch PS of the slits 63 is finer than the arrangement pitch PF of the tape feeder 8A, each of the multiple used tapes TP that descend in parallel faces one or more slits 63. Therefore, the amount of sliding of the used tape TP is small, reducing the risk of interference with adjacent used tapes TP.

[0042] 5 shows an example of a used tape TP with a tape width of 8 mm. A used tape TP with a tape width of 4 mm acts in the same way as an 8 mm tape, and differs from Patent Document 2 in that it does not enter the slit 63 (slit width WS is 3.5 mm). Furthermore, the function of the slit 63 to prevent lateral sliding is not limited to the type of carrier tape. Therefore, by preventing the leading ends of multiple used tapes TP from sliding lateral, the risk of jamming due to mutual interference, such as entanglement of multiple used tapes TP, is reduced.

[0043] When a predetermined cutting condition is met, the control device 96 operates the drive mechanism 33. As a result, the movable blade 32 moves forward and cuts all of the used tape TP at once, as shown in Figure 6. The multiple tape pieces TC generated by the cutting fall down the chute 4 and are collected in the dust box 5.

[0044] In the used tape processing device 1 of the embodiment, the slide cover 6 provided integrally with the movable blade 32 covers the gap G that is structurally generated around the movable blade 32, preventing the used tape TP that has passed between the fixed blade 31 and the movable blade 32 from entering the gap G. In addition, multiple slits 63 formed parallel to the guide surface 62 of the slide cover 6 suppress lateral sliding of the leading edges of the multiple used tapes TP. Therefore, the used tape processing device 1 can reduce the risk of jamming of the used tape TP compared to the prior art.

[0045] 5. Applications and Modifications of the Embodiments Although the semi-peeling type integrated reel tape feeders (8A, 8B) have been exemplified as the target of application of the used tape processing device 1, the present invention is not limited to this. In other words, the target of application may also be a full-peeling type tape feeder that processes the base tape and cover tape separately, or a separate-reel type tape feeder in which the reel is placed separately from the reel holding device. In the case of a full-peeling type tape feeder, the discharged base tape becomes the used tape TP.

[0046] The used tape processing device 1 may also be provided on a pallet table 931 instead of the base 91. Furthermore, the pallet table 931 may be formed in the shape of a dolly having casters for movement. In this aspect, the component supply device 93 includes the used tape processing device 1 and tape feeders (8A, 8B), and is detachably mounted on the component mounting machine 9. The used tape processing device 1 may also be configured in a split arrangement, with some of the components provided on the base 91 and the remaining components provided on the pallet table 931. The embodiments can be subject to various other applications and modifications. [Explanation of symbols]
