Description

[Technical Field]

[0001] The present specification relates to a tape transport assist device and an automatic tape loading device. [Background technology]

[0002] For example, an automatic tape loader is known from the past, as disclosed in Patent Document 1. The conventional automatic tape loader includes a tape transport device that transports a carrier tape wound on a tape reel, and the tape transport device transports the carrier tape to a component supply position provided in a tape feeder, thereby loading the carrier tape into the tape feeder. Here, the tape transport device has transport rollers consisting of a cylindrical drive roller and a driven roller, and transports the carrier tape while passing it between the drive roller and the driven roller. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5877891 Summary of the Invention [Problem to be solved by the invention]

[0004] The carrier tape transported by the tape transport device is an embossed tape, which has cavities formed in the base tape that forms the carrier tape to accommodate the components to be supplied. The embossed tape is thicker than a paper tape that does not have cavities.

[0005] In the tape transport device of a conventional automatic tape loader, the transport roller is cylindrical. In this case, when transporting a thin carrier tape such as a paper tape, the carrier tape can be easily passed between the drive roller and the driven roller, and the transport roller can smoothly transport the carrier tape.

[0006] However, when feeding a thick carrier tape such as an embossed tape, the carrier tape cannot easily pass between the drive roller and the driven roller (cannot slip under), and as a result, the carrier tape may get stuck in front of the feed roller. This can increase the workload and time required for the loading process of loading a thick carrier tape into a tape feeder, and there is room for improvement.

[0007] An object of the present specification is to provide a tape transport assist device and an automatic tape loading device that assist in the transport of a carrier tape in a loading process. [Means for solving the problem]

[0008] This specification discloses a tape transport auxiliary device that assists in transporting a carrier tape along a transport path of a tape feeder during a loading process in which a carrier tape formed by adhering a cover tape to the upper surface of a base tape having cavities for accommodating components at a fixed pitch is loaded into a tape feeder, the tape transport auxiliary device comprising a roller that is rotatably arranged while being biased to move the carrier tape along the transport path, and a recess provided on the peripheral surface of the roller that temporarily accommodates the front end of the carrier tape transported along the transport path during the loading process.

[0009] According to the tape transport auxiliary device, the auxiliary roller having the recessed portion urges the carrier tape without causing it to stagnate, in other words, it is possible to apply an appropriate propulsion force to the carrier tape to transport the carrier tape. This makes it possible to improve the success rate, which indicates the probability of properly loading the carrier tape into the tape feeder, during the loading process, and as a result, to reduce the workload and work time required for the loading process.

[0011] The tape transport assist device and the automatic tape loader will be described below with reference to the drawings. In this embodiment, the tape transport assist device will be described as being provided in an automatic tape loader.

[0012] (1. Automatic tape loader 1) As shown in FIG. 1-4, the automatic tape loading device 1 is a device that automatically loads a carrier tape T wound around a tape reel R (hereinafter also simply referred to as "reel R") into a tape feeder F (hereinafter also simply referred to as "feeder F"). In the following description, the tape transport direction when loading the carrier tape T is defined as the Y direction, the horizontal direction perpendicular to the Y direction is defined as the X direction, and the vertical direction perpendicular to the Y direction is defined as the Z direction.

[0013] As shown in Fig. 1, the automatic tape loading device 1 includes a feeder holder 10 that holds a feeder F, a tape transport device 20 and a tape transport auxiliary device 30 that transport a carrier tape T, and a control device 50. The feeder holder 10 is placed on a base B so that the feeder F it holds faces the Y direction. The control device 50 has a microcomputer as its main component and controls the overall operation of the automatic tape loading device 1.

[0014] Here, the carrier tape T wound around the reel R and the feeder F will be described with reference to FIGS. 2, 3, and 4. First, as shown in FIGS. 2 and 3, the carrier tape T has a cover tape T2 adhered to the upper surface of a base tape T1, and cavities T3 for accommodating components P are formed in the base tape T1 at a constant pitch d. That is, as shown in FIG. 3, the carrier tape T of this embodiment is a thick embossed tape in which the bottoms of the cavities T3 protrude from the lower surface of the base tape T1. Furthermore, the carrier tape T has a large number of feed holes T4 formed along one side edge. Generally, the base tape T1 is formed using a flexible material such as paper or resin, and the cover tape T2 is formed using a transparent and flexible polymer film or the like.

[0015] There are multiple types of reels R, each with different materials for the wound carrier tape T, different tape width dimensions for the carrier tape T, and different width dimensions for the reels R. There are also multiple types of feeders F into which these different types of reels R are loaded. For this reason, each reel R is marked with an identification code (e.g., a barcode or a two-dimensional code) that identifies the individual reel R and the type of feeder F into which it is loaded, although this is not shown in the figure.

[0016] The feeder F is loaded with a reel R wound with a carrier tape T, and supplies components P by feeding the carrier tape T in a component mounting machine (not shown). As shown in FIG. 4, the feeder F is formed thin and has a small width in the X direction (e.g., the left-right direction). The feeder F has a reel holding shaft F1 that protrudes rightward from the left side plate in FIG. 4, located approximately in the center when viewed from the side. The reel holding shaft F1 is inserted into a central hole formed in the center of the reel R to detachably and rotatably hold the reel R. The right side plate F2 of the feeder F has a large opening in the center to facilitate attachment and detachment of the reel R.

[0017] The feeder F further includes a component supply position F3, a sprocket F4, a tape feed guide F5, and a tape peeling unit (not shown). The component supply position F3 is located near the rear end of the upper surface of the feeder F. The sprocket F4 is rotatably located in front of the component supply position F3. The teeth of the sprocket F4 engage with the feed holes T4 of the carrier tape T. The sprocket F4 is intermittently driven by a drive motor (not shown) to feed the carrier tape T at a constant pitch. The tape feed guide F5 forms a transport path that guides the carrier tape T toward the sprocket F4. The tape peeling unit allows the carrier tape T to pass through the component supply position F3 with one side edge of the cover tape T2 constituting the carrier tape T peeled from the base tape T1 (in a so-called partially peeled state), enabling the component P to be removed by the component mounting machine. After passing the component supply position F3, the carrier tape T is cut, for example, by a tape cutting device provided in the component mounting machine.

[0018] Furthermore, although not shown, each feeder F is displayed with an identification code (e.g., a barcode or two-dimensional code) that identifies the type of feeder F. Also, a feeder control unit (not shown) is provided in the feeder F. The feeder control unit stores identification information that identifies the feeder F (and the reel R) and controls the component supply operation. When the feeder F is held on the feeder holder 10 of the automatic tape loader 1, a connector (not shown) automatically fits, enabling the feeder control unit to communicate with the outside (e.g., the control device 50).

[0019] As shown in Fig. 1, the feeder holder 10 has a base 11 that holds a feeder F (see Fig. 4) with a reel R attached to a reel holding shaft F1. The base 11 has a mounting portion 12 on which the bottom surface of the feeder F is placed, and an abutment portion 13 against which the rear end surface of the feeder F abuts. In this embodiment, a pair of support guides 14 that hold both side surfaces of the lower part of the feeder F are provided on the mounting portion 12. Although not shown, the abutment portion 13 is provided with a power supply portion that supplies power to the feeder F and a positioning portion that positions the feeder F.

[0020] (2. Tape carrier device 20) As shown in Figure 5, the tape transport device 20 includes a feed device 21 that transports the carrier tape T unwound from the reel R, a guide 22 that guides the transported carrier tape T, a support plate 23 that supports the feed device 21 and the guide 22, a base 24 on which the support plate 23 is placed and fixed, a transport movement device 25 that moves the base 24 in the X direction, and a sensor 29 that detects the leading end of the carrier tape T.

[0021] The feed device 21 includes a plurality of (four in this embodiment) drive rollers 26a, 26b, 26c, and 26d arranged along the tape transport direction (transport path), and driven rollers 27a and 27b arranged on the opposite side of the drive rollers 26a and 26b so as to abut against each other from below and rotate in accordance with the movement of the carrier tape T. Here, the drive rollers 26a and 26b and the driven rollers 27a and 27b form "transport rollers" that transport the carrier tape T along the transport path.

[0022] The four drive rollers 26a, 26b, 26c, and 26d are arranged side by side at predetermined intervals in the Y direction, i.e., the tape transport direction along the transport path, and are supported by a support plate 23. The driven rollers 27a and 27b are biased toward the drive rollers 26a and 26b by springs (not shown). The feed device 21 also includes drive motors 28a, 28b, 28c, and 28d that rotate and drive the drive rollers 26a, 26b, 26c, and 26d, respectively.

[0023] The guides 22 are supported by the support plate 23 so as to be positioned in front of the start drive roller 26a, between the four drive rollers 26a, 26b, 26c, and 26d, and ahead of the last drive roller 26d. More specifically, the guides 22a in front of the start drive roller 26a, ahead of the second drive roller 26b, and between the drive rollers 26a and 26b are formed by pairs of upper and lower guides in accordance with the arrangement of the drive rollers 26a and 26b and the driven rollers 27a and 27b. Furthermore, the guides 22b in front of the third drive roller 26c, ahead of the last drive roller 26d, and between the drive rollers 26c and 26d are formed by a single guide in accordance with the arrangement of the drive rollers 26c and 26d.

[0024] When feeder F is held on feeder holder 10, tape feed guide F5 of feeder F is positioned between the third drive roller 26c in line and the tip of the last drive roller 26d. As a result, the carrier tape T being transported is guided through the gap between guide 22b and tape feed guide F5, i.e., the transport path. Also, tape feed guide F5 is not provided between the first drive roller 26a in line and the tip of the second drive roller 26b in line. As a result, the carrier tape T being transported is guided through the gap between the pair of guides 22a, i.e., the transport path.

[0025] The transfer moving device 25 includes a pair of rails 40 and an air cylinder 41. The pair of rails 40 are provided on a base B at a predetermined interval to extend in the X direction. A pedestal 24 is disposed on the pair of rails 40 so as to be slidable in the X direction. The air cylinder 41 is disposed between the pair of rails 40 on the base B and is connected to an air supply source (not shown), and a cylinder rod 41a is connected to the pedestal 24.

[0026] The sensor 29 is supported by the support plate 23 so as to be located above the tape entrance of a pair of guides 22a, which are arranged in front of the starting drive roller 26a (downstream in the tape transport direction), and detects whether the leading end of the carrier tape T has entered the tape entrance. The sensor 29 is connected to the control device 50. The control device 50 receives a detection signal from the sensor 29 to control the driving of the drive motors 28a, 28b, 28c, and 28d, i.e., the rotation of the drive rollers 26a, 26b, 26c, and 26d. The control device 50 also receives a detection signal from the sensor 29 to control the rotation of the sprocket F4, for example, in cooperation with the feeder control unit.

[0027] (3. Tape transport auxiliary device 30) The tape transport auxiliary device 30 is a device that mainly assists the carrier tape T in being transported along the transport path during the loading process in which the carrier tape T is loaded into the feeder F by the tape transport device 20. The tape transport auxiliary device 30 is disposed on the transport path of the carrier tape T downstream in the tape transport direction from the drive rollers 26a, 26b of the feed device 21. Like the tape transport device 20, the tape transport auxiliary device 30 is also supported by the support plate 23.

[0028] The tape transport auxiliary device 30 transports the carrier tape T unwound from the reel R toward the feeding device 21. To this end, the tape transport auxiliary device 30 includes an auxiliary roller 31, a drive motor 32 as a drive source, and a guide 33, as shown in FIGS.

[0029] As shown in FIG. 6, the auxiliary roller 31 has recesses 311 and protrusions 312 that are alternately arranged along the circumferential direction of the roller and formed on the circumferential surface along the direction of the axis O of the auxiliary roller 31. A plurality of recesses 311 are formed radially inward from the outer circumferential surface including the apex of the protrusion 312 so as to temporarily accommodate the leading edge of the carrier tape T. The recesses 311 are formed at equal intervals in the circumferential direction of the roller based on the pitch d of the cavities T3 of the carrier tape T shown in FIGS. 2 and 3. As a result, the recesses 311 can reliably and temporarily accommodate the leading edge of the carrier tape T approaching the auxiliary roller 31, while transporting the carrier tape T toward the feeding device 21, i.e., upstream in the tape transport direction, as will be described later.

[0030] Here, the auxiliary roller 31 is biased by a spring (not shown) toward the guide 33, that is, in the thickness direction of the carrier tape T when the carrier tape T is supported by the guide 33. As a result, when the auxiliary roller 31 rotates to transport the carrier tape T, it can transport the carrier tape T supported by the guide 33 while pressing the carrier tape T in the thickness direction. In other words, the auxiliary roller 31 can generate an appropriate frictional force between itself and the cover tape T2 of the carrier tape T.

[0031] The drive motor 32 is, for example, a stepping motor. The drive motor 32 is controlled by the control device 50, and drives the auxiliary roller 31 to rotate so as to synchronize with (more preferably rotate slightly faster than) the rotation of the drive rollers 26a, 26b, 26c, and 26d of the feed device 21 disposed upstream. This allows the auxiliary roller 31 to reliably transport the carrier tape T along the transport path (tape transport direction) while biasing the carrier tape T toward the feed device 21.

[0032] (5. Operation of the tape transport device 20 and the tape transport auxiliary device 30) Next, we will explain the operations of the tape transport device 20 and the tape transport auxiliary device 30. In the loading process, first, the tape transport auxiliary device 30 operates to transport the carrier tape T toward the tape entrance of the tape transport device 20. Therefore, when the loading process starts, the control device 50 drives the drive motor 32 of the tape transport auxiliary device 30 to rotate the auxiliary roller 31.

[0033] 7, when the leading end of the carrier tape T is supplied while being biased toward the auxiliary roller 31, the tape transport auxiliary device 30 temporarily accommodates the leading end of the carrier tape T in the recessed portion 311 of the auxiliary roller 31. That is, the auxiliary roller 31 accommodates the leading end of the carrier tape T by directing the leading end of the carrier tape T toward the interior of the auxiliary roller 31, in other words, by inserting the leading end of the carrier tape T into the recessed portion 311 formed along the circumferential direction and the direction of the axis O.

[0034] 7, if the auxiliary roller 31 is cylindrical and does not have the recessed portions 311 or the protruding portions 312, the front end of the carrier tape T comes into contact with the outer peripheral surface of the auxiliary roller 31. Therefore, in this case, the front end of the carrier tape T cannot be accommodated inside the auxiliary roller 31. That is, when the auxiliary roller 31 has the recessed portions 311 indicated by the solid arrows (thin lines) in FIG. 7, the length of penetration into the auxiliary roller 31 is longer by the amount corresponding to accommodating the front end of the carrier tape T, compared to when the auxiliary roller 31 does not have the recessed portions 311 indicated by the dashed two-dot arrows (thin lines) in FIG.

[0035] The multiple recesses 311 are formed at equal intervals along the circumferential direction of the auxiliary roller 31. Therefore, if the front end of the carrier tape T is not accommodated in the recesses 311, for example, if the front end abuts against the protrusions 312, the auxiliary roller 31 is rotated slightly by the drive motor 32 or manually. This allows the auxiliary roller 31 to accommodate the front end of the inserted carrier tape T in the recesses 311.

[0036] Next, as the auxiliary roller 31 further rotates while the carrier tape T is being urged toward the auxiliary roller 31, the convex portion 312, which is circumferentially adjacent to the concave portion 311 that accommodates the front end of the carrier tape T, comes into contact with the upper surface of the carrier tape T, as shown in Fig. 8. Then, as the auxiliary roller 31 further rotates, the convex portion 312 begins to press against the upper surface of the carrier tape T, as indicated by the straight arrow in Fig. 8. This generates a reaction force in the auxiliary roller 31, and the auxiliary roller 31 moves in the thickness direction of the carrier tape T, away from the guide 33, against the urging force of the spring.

[0037] 9, the entire auxiliary roller 31 is placed on the carrier tape T. When the auxiliary roller 31 is placed on the carrier tape T, the spring force causes the auxiliary roller 31 (more specifically, the convex portion 312) to press the carrier tape T toward the guide 33.

[0038] As a result, the auxiliary roller 31 can be rotated by the driving force of the drive motor 32, thereby urging the carrier tape T along the tape feeding direction (feeding path). In this state, the driving force of the drive motor 32 is transmitted as a propulsion force to the carrier tape T due to the frictional force between the convex portions 312 arranged along the circumferential direction of the auxiliary roller 31 and the cover tape Tb of the carrier tape T. As a result, the carrier tape T is urged and fed upstream along the tape feeding direction (feeding path), i.e., toward the feed device 21 of the tape feeding device 20.

[0039] In the tape transport device 20, the sensor 29 detects the entry of the carrier tape T transported by the tape transport auxiliary device 30 into the tape inlet. In response to this, the control device 50 drives the drive motors 28a, 28b, 28c, and 28d of the feed device 21.

[0040] In the feeding device 21, the carrier tape T is supplied while being biased in the tape feeding direction by the auxiliary roller 31 of the tape feeding auxiliary device 30. As a result, the biasing force, i.e., the propulsion force, of the carrier tape T moves the driven rollers 27a, 27b in a direction away from the drive rollers 26a, 26b against the biasing force of the springs. As a result, the carrier tape T enters a state where it is slipped between the drive rollers 26a, 26b and the driven rollers 27a, 27b. Then, as the drive rollers 26a, 26b are rotated by the driving force of the drive motors 28a, 28b, the carrier tape T is conveyed toward the upstream drive rollers 26c, 26d, and is finally loaded in a state where it is pitch-fed by the sprocket F4 of the feeder F.

[0041] As can be understood from the above explanation, the tape transport auxiliary device 30 assists in the transport of the carrier tape T along the transport path of the tape feeder F during a loading process in which the carrier tape T, which is formed by adhering a cover tape T2 to the upper surface side of a base tape T1 having cavities T3 in which components P are housed at a constant pitch d, is loaded into the tape feeder F. The tape transport auxiliary device 30 includes an auxiliary roller 31 that is rotatably provided while being biased to move the carrier tape T along the transport path, and a recess 311 is provided on the circumferential surface of the auxiliary roller 31 to temporarily accommodate the front end of the carrier tape T transported along the transport path during the loading process.

[0042] According to the tape transport auxiliary device 30, the auxiliary roller 31 having the recess 311 urges the carrier tape T, in other words, applies an appropriate propulsion force to the carrier tape T, thereby transporting the carrier tape T toward the tape transport device 20. This makes it possible to improve the success rate, which indicates the probability of properly loading the carrier tape T into the tape feeder F, in the loading process, and as a result, reduce the workload and time required for the loading process.

[0043] (6. Modifications) In the above-described embodiment, the tape transport auxiliary device 30 is provided in the automatic tape loader 1. However, it is also possible to provide the tape transport auxiliary device 30 in a device other than the automatic tape loader 1 that requires processing to transport the carrier tape T along the transport path (tape transport direction).

[0044] In the above-described embodiment, the tape transport auxiliary device 30 is provided in the automatic tape loader 1 that automatically transports the carrier tape T wound around the reel R to the component supply position F3 of the feeder F. That is, in the above-described embodiment, the tape transport auxiliary device 30 pays out the carrier tape T wound around the reel R, and continuously transports the paid-out carrier tape T toward the feed device 21 of the tape transport device 20.

[0045] Alternatively, for example, an operator may use the tape transport auxiliary device 30 to unwind the carrier tape T from the reel R, and then the unwound carrier tape T may be supplied (transported) to the feed device 21 of the tape transport device 20. In this case, the same effects as those of the above-described embodiment can be obtained.

[0046] Furthermore, in the above-described embodiment, the auxiliary roller 31 of the tape transport auxiliary device 30 has a plurality of recesses 311 along the circumferential direction. However, it is not necessary to provide a plurality of recesses 311 on the circumferential surface of the auxiliary roller 31. That is, it is also possible to provide only one recess 311 on the circumferential surface of the auxiliary roller 31. Even in this case, by aligning the recess 311 of the auxiliary roller 31 with the front end of the carrier tape T, the recess 311 can accommodate the front end of the carrier tape T, and therefore, the same effects as in the above-described embodiment can be expected.

[0047] In the above-described embodiment, the recesses 311 of the auxiliary roller 31 are arranged at equal intervals along the circumferential direction. However, the intervals at which the recesses 311 are formed are not limited to equal intervals. Even if the recesses 311 are not arranged at equal intervals, the recesses 311 can accommodate the front end of the carrier tape T and ride up onto the upper surface of the carrier tape T, and therefore the same effect as in the above-described embodiment can be expected.

[0048] Furthermore, in the above-described embodiment, a plurality of recesses 311 (and protrusions 312) are formed along the direction of the axis O of the auxiliary roller 31. However, for example, in a state in which the tape feed direction (feed path) of the carrier tape T is not perpendicular to the axis O of the auxiliary roller 31, it is also possible to form the recesses 311 (and protrusions 312) without following the axis O of the auxiliary roller 31. Even in this case, the recesses 311 can accommodate the front end of the carrier tape T, and therefore the same effect as in the above-described embodiment can be expected. [Explanation of symbols]
