Description

[Technical field]

[0001] The present specification relates to a reel holding device used in combination with a feeder equipped in a component mounting machine. [Background technology]

[0002] A technology for mass-producing board products by performing substrate-to-board operations on printed wiring boards has become widespread. A typical example of a substrate-to-board operation machine is a component mounting machine that performs component mounting operations. Many component mounting machines are equipped with a feeder that unwinds a carrier tape to supply components. In addition, a reel holding device that rotatably holds a reel on which a carrier tape is wound is also used. Reel holding devices include an integrated type that is integrated with the feeder, and a separate type that is separate from the feeder. In addition, methods for rotatably holding a reel include a center support method in which a pin member supports the center hole of the reel, and an outer periphery support method in which multiple roller members support the outer periphery of the reel. In the outer periphery support method, care must be taken to prevent the reel from floating up when the carrier tape is pulled out. One technical example of this type of reel holding device is disclosed in Patent Document 1.

[0003] Patent Document 1 describes a reel holder with a slide groove extending between a replacement position and an operating position. In this reel holder, a central shaft supporting a central hole of the reel slides along the slide groove between the replacement position and the operating position. This allows the reel to be moved together with the central shaft, making reel replacement easy. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-182838 A Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, there is a need to change the holding position (operating position) of the reel depending on the size of the reel diameter, not limited to the configuration of Patent Document 1. For example, in a configuration in which a feeder is detachably mounted at the rear of a component mounting machine and a reel holding device is further disposed at the rear lower part, the reel tends to get in the way when the feeder is pulled out backward. Even so, it is possible to hold a small diameter reel in a position below the feeder pull-out path where it does not get in the way. On the other hand, a large diameter reel is held at a higher position than a small diameter reel by the amount of its larger diameter. In addition, it is also possible to change the holding position of the reel depending on the reel diameter in order to facilitate the reel replacement work or to adjust the pull-out path of the carrier tape.

[0006] Therefore, an object of this specification is to provide a reel holding device that is capable of changing the holding position of a reel depending on the reel diameter. [Means for solving the problem]

[0007] This specification discloses a reel holding device that is equipped on a component mounting machine and is used in combination with a feeder that pays out a carrier tape containing a plurality of components and supplies the components, and that rotatably holds a reel on which the carrier tape is wound, the reel holding device comprising: a pallet; a thin plate-shaped partition member that is uprightly mounted on the pallet; and a pin member that is repositionably mounted on the partition member in response to differences in diameter of the reel, and that supports a center hole of the reel or contacts the outer periphery of the reel to regulate floating of the reel. Effect of the Invention

[0008] In the reel holding device disclosed in this specification, the pin member that supports the center hole of the reel or contacts the outer periphery of the reel is provided on the partition member so that its position can be changed according to the difference in the diameter of the reel. Therefore, it is possible to change the holding position of the reel according to the reel diameter. As an effect of changing the holding position of the reel, for example, it is possible to reduce the labor required for replacing the feeder. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] 1. Configuration of the feeder 92 and its relationship with the reel holding device 1 of the embodiment First, the configuration of the feeder 92 and its relationship with the reel holding device 1 of the embodiment will be described with reference to Figures 1 and 2. As shown by the arrows at the upper left of Figures 1 and 2, the up-down, front-rear, left-right directions common to the component mounting machine 91, the feeder 92, and the reel holding device 1 are defined. The reel holding device 1 of the embodiment is used in combination with the feeder 92 equipped on the component mounting machine 91.

[0011] 1 and 2, a feeder pallet 93 is detachably provided at approximately the middle height of the rear part of the component mounting machine 91. The feeder pallet 93 is composed of a substantially rectangular flat portion 931 and an upright portion 935 standing upright from the front side of the flat portion 931. The flat portion 931 has a plurality of slots 932 arranged in the width direction and formed in a groove shape extending in the front-rear direction. Positioning portions 936 and connectors 937 are provided on the rear surface of the upright portion 935 at positions corresponding to each slot 932.

[0012] The feeder 92 is formed to be thin in the width direction, and a positioning portion 926 and a connector 927 are provided on its front surface. The feeder 92 is inserted from the rear of the slot 932 toward the front upright portion 935 along the horizontal pull-out path 94 and installed. At this time, the positioning portions (926, 936) engage with each other to position the feeder 92. Furthermore, the connectors (927, 937) are fitted together to supply power to the feeder 92 and establish a communication connection. FIG. 2 illustrates a state in which three feeders 92 are installed in every other slot 932. During operation, many more feeders 92 are installed on the feeder pallet 93. Furthermore, the feeder 92 is pulled out rearward along the pull-out path 94 and removed.

[0013] The feeder 92 has a tape insertion opening 921 near the middle height on the rear side, and a component supply position 922 on the upper front side. The feeder 92 has a tape feeding mechanism (not shown), and pays out the carrier tape CT inserted into the tape insertion opening 921 toward the component supply position 922. The cover tape of the carrier tape CT is peeled off while being paid out to the component supply position 922, making it possible to pick up components.

[0014] The reel holding device 1 is disposed at the rear lower part of the feeder 92 as shown in FIG. 1. More specifically, arm members 95 are provided at the left and right ends of the rear part of the feeder pallet 93. The arm members 95 are formed in an upright plate shape, and initially extend horizontally rearward, then extend at an incline downward rearward, and finally extend horizontally rearward. A front mounting seat 951 that protrudes outward is provided at the inclined portion of the pair of left and right arm members 95. A rear mounting seat 952 that protrudes outward is provided at the horizontal portion on the rear side of the pair of left and right arm members 95. The reel holding device 1 is configured on the front mounting seat 951 and the rear mounting seat 952. The reel holding device 1 rotatably holds a reel (RS) on which a carrier tape CT that contains a plurality of components is wound, and feeds the carrier tape CT to the feeder 92.

[0015] 2. Configuration and Function of Reel Holding Device 1 of the Embodiment Next, the configuration and function of the reel holding device 1 of the embodiment will be described with reference to Figs. 1 to 4. The reel holding device 1 can hold a plurality of types of reels with different diameters. For example, there are small diameter reels RS with a diameter of 7 inches, and large diameter reels RL with a diameter of 13 inches or 15 inches (see Fig. 7), but the types of reels are not limited to these. Fig. 1 shows two small diameter reels RS as an example, and Fig. 2 shows six small diameter reels RS as an example. A central hole CH with a common hole diameter DH that is independent of the reel diameter is formed in the center of each reel (RS, RL) (see Fig. 4).

[0016] The number of reels (RS, RL) that the reel holding device 1 can hold is equal to the maximum number of feeders 92 that can be installed on the feeder pallet 93. In this embodiment, it is difficult to reduce the arrangement pitch of the reels (RS, RL) in the width direction to the arrangement pitch of the feeders 92. For this reason, the width dimension of the reel holding device 1 is slightly larger than the width dimension of the feeder pallet 93.

[0017] The reel holding device 1 is composed of a pallet 2, a partition member 3, a pin member 5, and the like. The pallet 2 is composed of a bottom plate 21, a pair of left and right side plates 23, a front mounting shaft 24, and a rear mounting shaft 25, and the like. The bottom plate 21 is a plate-like member extending horizontally in the left-right direction, and is fixed by spanning between the left and right rear mounting seats 952. A handle 22 is provided at the center in the left-right direction on the rear side of the bottom plate 21. By pulling the handle 22 backward, an operator can transfer the feeder pallet 93, the multiple feeders 92, and the reel holding device 1 together from the component mounting machine 91 to a replacement cart (not shown).

[0018] The side plate 23 is a plate material having a shape of a roughly right-angled triangle. A first side of the side plate 23 that sandwiches the right angle extends from the front lower part to the rear part, a second side that sandwiches the right angle extends from the front lower part to the front upper part, and a hypotenuse extends from the front upper part to the rear part. The pair of left and right side plates 23 have bottom surfaces 231 that bend inwardly facing each other. The bottom surfaces 231 are fixed to the front mounting base 951 by one screw 232 and are fixed to the rear mounting base 952 by two screws 233. As a result, the pair of left and right side plates 23 are fixed perpendicularly to the outwardly protruding edges of the front mounting base 951 and the rear mounting base 952 as shown in FIG. 2.

[0019] The front mounting shaft 24 connects the front upper portions of the pair of left and right side plates 23. The rear mounting shaft 25 connects the rear portions of the pair of left and right side plates 23. The front mounting shaft 24 and the rear mounting shaft 25 are shaft members that extend in the left-right direction and are provided with a plurality of mounting grooves 26 that go around in the circumferential direction. The spacing pitch PD of the multiple mounting grooves 26 is set to be larger than twice the thickness dimension TR of the reels (RS, RL).

[0020] The pallet 2 further has four pairs of roller shafts (61, 62, 63, 64). The upper roller shaft 61 connects the pair of left and right side plates 23 at a position on the front upper side and rearward and upward from the front mounting shaft 24. The front roller shaft 62 connects the pair of left and right side plates 23 at the front lower side. The middle roller shaft 63 connects the pair of left and right side plates 23 at the lower part approximately in the middle in the front-to-rear direction. The rear roller shaft 64 connects the rear parts of the pair of left and right side plates 23.

[0021] Each roller shaft (61, 62, 63, 64) has a plurality of outer periphery support members 65. Each of the outer periphery support members 65 is formed as a cylindrical roller member and is rotatably held by the roller shaft (61, 62, 63, 64). The number of outer periphery support members 65 corresponds to the maximum number of reels (RS, RL) that the reel holding device 1 can hold. The width dimension WS of the outer periphery support member 65 is slightly larger than the thickness dimension TR of the reel (RS, RL). The outer periphery support member 65 can rotatably support the outer periphery of the reel (RS, RL). However, when a fixed pin 33 or a pin member 5 described later is used, the outer periphery support member 65 is not used in combination.

[0022] The partition member 3 is a thin plate-like member that is long in the front-rear direction. The partition member 3 is attached upright in the attachment grooves 26 of the front attachment shaft 24 and the rear attachment shaft 25 of the pallet 2. The partition member 3 is disposed below the pull-out path 94. The partition member 3 has a front attachment groove 31 at the upper part of the front edge, and a rear attachment groove 32 near the rear of the lower edge. The front attachment groove 31 extends rearward from the front edge of the partition member 3. The rear attachment groove 32 extends upward from the lower edge of the partition member 3 and then bends forward, forming a substantially L-shape.

[0023] In the procedure for attaching the partition member 3 to the pallet 2, first, the partition member 3 is advanced from rear to front, and the front mounting groove 31 is inserted into the mounting groove 26 of the front mounting shaft 24. Next, the rear part of the partition member 3 is lowered, and the rear mounting groove 32 is inserted into the mounting groove 26 of the rear mounting shaft 25. Finally, the partition member 3 is pulled back slightly rearward, and the rear mounting shaft 25 is fitted into the bent innermost part of the rear mounting groove 32. This stabilizes the mounting posture of the partition member 3. The procedure for removing the partition member 3 is generally the reverse of the above-mentioned mounting procedure. As described above, the procedure for attaching and detaching the partition member 3 is easy, and no mounting members such as tools or screws are required.

[0024] FIG. 2 illustrates three partition members 3 provided on the left side of the pallet 2. During operation, many more partition members 3 are provided on the pallet 2 in parallel to each other. The maximum number of partition members 3 is equal to half the maximum number of the feeders 92 that can be installed. By making the partition members 3 detachable, the partition members 3 can be appropriately arranged according to the number and arrangement of the installed feeders 92. Furthermore, it becomes possible to use a plurality of types of reels with different thickness dimensions TR. A fixing pin 33 is provided protruding horizontally at approximately the middle height near the rear of the left side surface of the partition member 3. The fixing pin 33 rotatably supports the center hole CH of the reel (RS, RL).

[0025] As shown in FIG. 3, the partition member 3 has a moving groove 4 in which the pin member 5 moves. The moving groove 4 is formed through a plurality of mounting positions where the pin member 5 can stop (be mounted). More specifically, the moving groove 4 starts from a large diameter mounting position 41 located at the upper part of the partition member 3 in the middle in the front-rear direction. The moving groove 4 extends slightly upward from the large diameter mounting position 41, immediately bends and extends backward, then bends sharply and extends forward and downward, and reaches a small diameter mounting position 42. Furthermore, the moving groove 4 bends sharply at the small diameter mounting position 42, extends slightly diagonally upward and backward, and further bends downward to reach a standby position 43, which is an end point. The standby position 43 is located in front of the fixed pin 33.

[0026] As described above, the moving groove 4 connects the multiple attachment positions (41, 42, 43) in a single stroke and has no branching or intersection points. This suppresses a decrease in the mechanical rigidity of the partition member 3, and prevents the pin member 5 from falling off due to deformation of the partition member 3. In addition, since the large diameter attachment position 41 and the standby position 43 correspond to the lowered ends (starting point and ending point) of the moving groove 4, the position of the moved pin member 5 is stable.

[0027] The pin member 5 is provided so as to protrude horizontally from the right side surface of the partition member 3. The pin member 5 rotatably supports the central hole CH of the reel (RS, RL). As shown in FIG. 4, the pin member 5 is composed of a pin body 51 and a retaining plate 54. The pin body 51 has a flange-shaped head 52 and a shaft portion 53. The diameter D1 of the head 52 is approximately equal to or slightly smaller than the hole diameter DH of the central hole CH of the reel (RS, RL). The diameter D2 of the shaft portion 53 is smaller than the diameter D1 of the head 52 and slightly smaller than the groove width WC of the moving groove 4. The length LZ of the shaft portion 53 is slightly larger than the sum of the thickness dimension TR of the reel (RS, RL) and the thickness dimension TS of the partition member 3. The retaining plate 54 is a disk-shaped member. The diameter D3 of the retaining plate 54 is larger than the diameter D1 of the head 52.

[0028] When attaching the pin member 5 to the moving groove 4, the worker moves the pin body 51 closer to the partition member 3 from the right side and passes the tip of the shaft portion 53 through the moving groove 4. Next, the worker fixes the retaining plate 54 to the tip of the shaft portion 53. Since the diameter D2 of the shaft portion 53 is smaller than the groove width WC of the moving groove 4, the worker can move the pin member 5 along the moving groove 4. Furthermore, since the diameter D1 of the head portion 52 and the diameter D3 of the retaining plate 54 are larger than the groove width WC of the moving groove 4, the pin member 5 will not fall off from the moving groove 4.

[0029] In addition, the head 52 of the pin body 51 passes through the center hole CH of the reel (RS, RL) with the bare minimum. Therefore, the operator can attach the reel (RS, RL) by moving it from the head 52 to the shaft 53. The pin member 5 can move along the movement groove 4 even with the reel (RS, RL) attached. The reel (RS, RL) supported by the shaft 53 does not easily come off the head 52, and rotates while maintaining its attached state.

[0030] 3. Method of Use and Function of Reel Holding Device 1 Next, the use and operation of the reel holding device 1 of the embodiment will be described with reference to Figures 5 to 9. When using a small diameter reel RS, an operator moves the pin member 5 supporting the center hole CH of the small diameter reel RS to the small diameter mounting position 42. This results in the state shown in Figure 5. In Figure 5, the reel holding device 1 and the small diameter reel RS are located below the pull-out path 94 and do not interfere with the replacement work of the feeder 92.

[0031] In other words, the pin member 5 supporting the center hole CH of the small diameter reel RS supports the small diameter reel RS at a position where the upper end of the small diameter reel RS is below the pull-out path 94 of the feeder 92 when the diameter of the small diameter reel RS is equal to or smaller than a predetermined value. Here, the predetermined value is 7 inches, which corresponds to the diameter of the small diameter reel RS. This reduces the effort required for replacing the feeder 92. If the small diameter reel RS were to get stuck in the pull-out path 94, it would be necessary to temporarily remove the small diameter reel RS when replacing the feeder 92, which would be extra work.

[0032] Furthermore, when the carrier tape CT is pulled out from the small diameter reel RS by the operation of the feeder 92, the tension of the carrier tape CT pulls the small diameter reel RS in a direction to float it. As a result, a buoyancy force F1 acts on the pin member 5 from the small diameter reel RS. The moving groove 4 extends at an angle A and an angle B with respect to the direction of the buoyancy force F1. The angles A and B are approximately 90° or more. Therefore, even if the buoyancy force F1 acts, the pin member 5 does not move from the small diameter mounting position 42, and the small diameter reel RS does not float. Furthermore, the moving groove 4 extends obliquely upward from the small diameter mounting position 42. Therefore, the pin member 5 and the small diameter reel RS do not move due to the influence of their own weight. Therefore, the small diameter reel RS rotates stably around the small diameter mounting position 42.

[0033] The installation and replacement of the small diameter reel RS is performed as shown in Fig. 6. That is, the worker moves the pin member 5 to the large diameter mounting position 41, and bends the partition member 3 to install the small diameter reel RS on the pin member 5. Next, the worker moves the pin member 5 supporting the small diameter reel RS along the moving groove 4 to the small diameter mounting position 42. The worker also moves the pin member 5 supporting the small diameter reel RS from the small diameter mounting position 42 to the large diameter mounting position 41, and bends the partition member 3 to remove the small diameter reel RS.

[0034] For these operations, it is necessary to bend the partition member 3 to widen the gap between the adjacent partition member 3 or side plate 23. For this reason, it is difficult to perform the operation at the small diameter mounting position 42 close to the fixed parts of the partition plate 3 (the front mounting groove 31 and the rear mounting groove 32), but it is easy to perform the operation at the large diameter mounting position 41 away from the fixed parts. As described above, the large diameter mounting position 41 also serves as a replacement position for replacing the small diameter reel RS. Note that the replacement operation of the small diameter reel RS is possible not necessarily at the large diameter mounting position 41, but within the range of a high position close to the large diameter mounting position 41 of the moving groove 4.

[0035] 2, the reel holding device 1 can support the small diameter reel RS by using the pin member 5 near the front of the right side of the partition member 3, and by using the fixed pin 33 near the rear of the left side. The two small diameter reels RS are used in combination with two feeders 92 that are installed side by side. The carrier tape CT pulled out from the small diameter reel RS is inserted into the feeder 92 while being allowed to move obliquely up to about three times the thickness dimension TR of the reel (RS, RL). In addition, the small diameter reel RS on the left side is located on the extension line of the rear of the pull-out path 94, so it does not hinder the replacement work of the feeder 92 regardless of the height at which it is held.

[0036] Next, when using the large diameter reel RL, the operator holds the pin member 5 supporting the center hole CH of the large diameter reel RL in the large diameter mounting position 41. This results in the state shown in Figure 7. In Figure 7, the large diameter reel RL with a diameter of 15 inches is shown in solid lines, and the large diameter reel RL with a diameter of 13 inches is shown in dashed lines.

[0037] When the carrier tape CT is pulled out from the large diameter reel RL by the operation of the feeder 92, the tension of the carrier tape CT pulls the large diameter reel RL in a direction that lifts it up. This causes a buoyancy force F2 to act on the pin member 5 from the large diameter reel RL. Because the buoyancy force F2 is directed generally forward, the pin member 5 hardly rises from the large diameter mounting position 41, and even if it does rise, it will not move backward along the movement groove 4. Therefore, the large diameter reel RL rotates stably around the large diameter mounting position 41.

[0038] The large diameter reel RL can be attached or replaced at the large diameter mounting position 41. In other words, the large diameter mounting position 41 also serves as a replacement position for replacing the large diameter reel RL. As shown in FIG. 8, the reel holding device 1 can support the large diameter reel RL at the front of the right side of the partition member 3 using the pin member 5, and can support the large diameter reel RL at the rear of the left side of the partition member 3 using the fixing pin 33. Two large diameter reels RL are used in combination with two feeders 92 that are installed side by side. The large diameter reel RL on the left side is located on the extension line of the rear of the pull-out path 94, so it does not hinder the replacement work of the feeder 92 regardless of the height at which it is held. Furthermore, the reel holding device 1 can also support reels (RS, RL) of different sizes on the right side and left side of the partition member 3.

[0039] 9, a holding method can be used in which the large reel RL is supported by an outer periphery support member 65, without using the pin member 5. In this case, the operator moves the pin member 5 to the retracted position 43. This ensures that the pin member 5 does not get in the way when inserting the large reel RL between the two partition members 3. The inserted large reel RL has its outer periphery supported by the outer periphery support members 65 of the upper roller shaft 61, the middle roller shaft 63, and the rear roller shaft 64.

[0040] Also, the small diameter reel RS can be supported by the outer circumferential support members 65 of the front roller shaft 62 and the middle roller shaft 63, or by the outer circumferential support members 65 of the middle roller shaft 63 and the rear roller shaft 64. In this case as well, the worker moves the pin members 5 to the retracted position 43. Since the pin members 5 stop at the retracted position 43, they do not impede the rotation of the reels (RS, RL) or the pulling out of the carrier tape CT. If the pin members 5 are left somewhere along the way in the moving groove 4, they may gradually move while the component mounting machine 91 is in operation, causing a malfunction.

[0041] In the reel holding device 1 of the embodiment, the pin member 5 supporting the center hole CH of the reel (RS, RL) is provided on the partition member 3 so that its position can be changed according to the difference in diameter of the reel (RS, RL). Therefore, it is possible to change the holding position of the reel (RS, RL) according to the reel diameter. As an effect of changing the holding position of the reel (RS, RL), for example, it is possible to reduce the effort required for replacing the feeder 92.

[0042] 4. Applications and Modifications of the Embodiments The fixed pin 33 on the left side surface of the partition member 3 may be omitted. The minimum configuration of the reel holding device 1 is composed of the pallet 2, one partition member 3 from which the fixed pin 33 is omitted, and one pin member 5 that moves in the moving groove 4 of the partition member 3. The partition member 3 may have two moving grooves 4, and a movable pin member 5 may be provided instead of the fixed pin 33 on the left side surface. Furthermore, in order to accommodate multiple types of reels with different thickness dimensions TR, multiple types of partition members 3 with different lengths of the fixed pin 33 and the pin member 5 may be used in combination. The purpose of changing the holding position of the reels (RS, RL) according to the reel diameter may be to facilitate the replacement work of the reels (RS, RL) or to adjust the drawing path of the carrier tape CT from the reels (RS, RL) to the feeder 92.

[0043] Also, the partition member 3 may not have the moving groove 4, but may have mounting holes at the large diameter mounting position 41, the small diameter mounting position 42, and the standby position 43, respectively, and the pin member 5 may be attached and detached to the mounting holes. However, with this configuration, there is a risk of losing the pin member 5, but in this embodiment, there is no risk of losing the pin member 5. Furthermore, the movable pin member 5 supports the center hole CH of the reel (RS, RL), but may also come into contact with the outer periphery of the reel (RS, RL) to restrict the floating of the reel (RS, RL). This embodiment can be subject to various other applications and modifications. [Explanation of symbols]
