Description

The present specification relates to a reel holding device used in combination with a feeder mounted on a component mounting machine.

A technique for mass-producing board products by carrying out board-to-board work on a board with printed wiring is widespread. As a typical example of a board-to-board work machine that performs board-to-board work, there is a component mounting machine that carries out component mounting work. Many component mounting machines are equipped with a feeder that feeds out carrier tape to supply components. Further, a reel holding device for rotatably holding the reel around which the carrier tape is wound is also used. The reel holding device includes an integrated type that is integrally incorporated in the feeder and a separate type that is separate from the feeder. Further, as a method of holding the reel rotatably, there are a center support method in which the center hole of the reel is supported by a pin member and an outer circumference support method in which the outer circumference of the reel is supported by a plurality of roller members. In the outer peripheral support method, care must be taken so that the reel does not float when the carrier tape is pulled out. A technical example of this type of reel holding device is disclosed in Patent Document 1.

Patent Document 1 describes a reel holder in which a slide groove extending between a replacement position and an operating position is formed. In this reel holder, the central axis supporting the center hole of the reel slides along the slide groove between the replacement position and the operating position. According to this, the reel can be moved together with the central axis, and the reel replacement work is easy.

JP-A-2010-182838

By the way, not limited to the configuration of Patent Document 1, there is a need to change the holding position (operating position) of the reel according to the size of the reel diameter. For example, in a configuration in which a feeder is detachably mounted on the rear portion of a component mounting machine and a reel holding device is arranged on the lower rear portion thereof, the reel tends to be an obstacle when the feeder is pulled out rearward. Nevertheless, the small diameter reel can be held in an unobtrusive position below the feeder withdrawal path. On the other hand, the large-diameter reel is held at a higher position than the small-diameter reel due to the larger diameter. It is also conceivable to change the reel holding position according to the reel diameter for the purpose of facilitating the reel replacement work and adjusting the carrier tape withdrawal path.

Therefore, in the present specification, it is a problem to be solved to provide a reel holding device capable of changing the holding position of the reel according to the reel diameter.

This specification is used in combination with a feeder that is equipped in a component mounting machine and contains a plurality of components to feed out and supply the components, and holds the reel around which the carrier tape is wound rotatably. A reel holding device, the pallet, a thin plate-shaped partition member provided upright on the pallet, and the partition member that can be repositioned according to a difference in the diameter of the reel, and a center hole of the reel. Discloses a reel holding device comprising a pin member that supports or contacts the outer periphery of the reel to regulate the floating of the reel.

In the reel holding device disclosed in the present specification, the pin member that supports the center hole of the reel or comes into contact with the outer circumference of the reel is provided in the partition member so as to be repositionable 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, the labor of replacing the feeder can be reduced.

1. 1. Configuration of Feeder 92 and Relationship with Reel Holding Device 1 of the Embodiment First, the configuration of the feeder 92 and the relationship with the reel holding device 1 of the embodiment will be described with reference to FIGS. 1 and 2. As shown by the arrows on the upper left of FIGS. 1 and 2, the vertical, front, rear, and horizontal directions common to the component mounting machine 91, the feeder 92, and the reel holding device 1 are determined. The reel holding device 1 of the embodiment is used in combination with the feeder 92 mounted on the component mounting machine 91.

As shown in FIGS. 1 and 2, the feeder pallet 93 is detachably provided at a substantially intermediate height at the rear portion of the component mounting machine 91. The feeder pallet 93 is composed of a substantially rectangular flat surface portion 931 and an upright portion 935 that stands up from the front side of the flat surface portion 931. The flat surface portion 931 has a plurality of slots 932 formed in a groove shape extending in the front-rear direction and arranged in the width direction. A positioning portion 936 and a connector 937 are provided at positions corresponding to the respective slots 932 on the rear surface of the upright portion 935.

The feeder 92 is formed thin in the width direction, and a positioning portion 926 and a connector 927 are provided on the front surface thereof. The feeder 92 is inserted and equipped along the horizontal withdrawal path 94 from the rear of the slot 932 toward the front upright portion 935. At this time, the feeder 92 is positioned by the engagement between the positioning portions (926, 936). Further, by fitting the connectors (927, 937) to each other, power is supplied to the feeder 92, and communication is further connected. FIG. 2 illustrates a state in which three feeders 92 are installed in every other slot 932. During operation, a larger number of feeders 92 are mounted on the feeder pallet 93. Further, the feeder 92 is pulled out rearward along the withdrawal path 94 and is removed.

The feeder 92 has a tape insertion port 921 near an intermediate height on the rear side, and a component supply position 922 on the upper part on the front side. The feeder 92 has a tape feeding mechanism (not shown), and feeds the carrier tape CT inserted into the tape insertion port 921 toward the component supply position 922. In the carrier tape CT, the cover tape is peeled off while being fed to the component supply position 922, and the component can be collected.

The reel holding device 1 is arranged at the rear lower portion of the feeder 92 as shown in FIG. More specifically, arm members 95 are provided at the left and right ends of the rear portion of the feeder pallet 93, respectively. The arm member 95 is formed in an upright plate shape, initially extending horizontally rearward, then inclined rearward and downward, and finally extending horizontally rearward. A front mounting seat 951 projecting outward is provided on an inclined portion of the pair of left and right arm members 95. A rear mounting seat 952 that projects outward is provided in a 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 the reel (RS) around which the carrier tape CT containing a plurality of parts is wound, and feeds the carrier tape CT to the feeder 92.

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 having different diameters. For example, there are a small diameter reel RS having a diameter of 7 inches, a large diameter reel RL having a diameter of 13 inches or a diameter of 15 inches (see FIG. 7), and the type of reel is not limited to these. FIG. 1 illustrates two small-diameter reels RS, and FIG. 2 illustrates six small-diameter reels RS. At the center of each reel (RS, RL), a center hole CH having a common hole diameter DH that does not depend on the reel diameter is formed (see FIG. 4).

The number of reels (RS, RL) that can be held by the reel holding device 1 is equal to the maximum number of feeders 92 that can be mounted on the feeder pallet 93. In the present embodiment, it is difficult to reduce the arrangement pitch of the reels (RS, RL) in the width direction to the arrangement pitch of the feeder 92. Therefore, the width dimension of the reel holding device 1 is slightly larger than the width dimension of the feeder pallet 93.

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, a rear mounting shaft 25, and the like. The bottom plate 21 is a plate-shaped member extending horizontally in the left-right direction, and is bridged and fixed to 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 rearward, the operator can collectively transfer the feeder pallet 93, the plurality of feeders 92, and the reel holding device 1 from the component mounting machine 91 to the replacement carriage (not shown).

The side plate 23 is a plate material having a substantially right triangle. The first side sandwiching the right angle of the side plate 23 extends from the lower part of the front side to the rear part, the second side sandwiching the right angle extends from the lower part of the front side to the upper part of the front side, and the hypotenuse extends from the upper part of the front side to the rear part. The pair of left and right side plates 23 have a bottom surface 231 that bends inward facing each other. The bottom surface 231 is fixed to the front mounting seat 951 with one screw 232 and fixed to the rear mounting seat 952 with two screws 233. As a result, the pair of left and right side plates 23 are vertically fixed to the outwardly projecting edges of the front mounting seat 951 and the rear mounting seat 952, as shown in FIG.

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

The pallet 2 further has four sets of roller shafts (61, 62, 63, 64). The upper roller shaft 61 is a position of the upper front side of the pair of left and right side plates 23, and joins a position rearward and upper side of the front side mounting shaft 24. The front roller shaft 62 connects the lower front side of the pair of left and right side plates 23. The middle roller shaft 63 connects the lower part of the pair of left and right side plates 23 around the middle in the front-rear direction. The rear roller shaft 64 connects the rear portions of the pair of left and right side plates 23.

Each roller shaft (61, 62, 63, 64) has a plurality of outer peripheral support members 65. Each of the outer peripheral support members 65 is formed in a cylindrical roller member and is rotatably held by roller shafts (61, 62, 63, 64). The number of outer peripheral support members 65 corresponds to the maximum number of reels (RS, RL) that can be held by the reel holding device 1. The width dimension WS of the outer peripheral support member 65 is slightly larger than the thickness dimension TR of the reels (RS, RL). The outer peripheral support member 65 can rotatably support the outer circumference of the reel (RS, RL). However, when the fixing pin 33 and the pin member 5 described later are used, the outer peripheral support member 65 is not used together.

The partition member 3 is a thin plate-shaped member that is long in the front-rear direction. The partition member 3 is mounted upright in the mounting groove 26 of the front mounting shaft 24 and the rear mounting shaft 25 of the pallet 2. The partition member 3 is arranged below the withdrawal path 94. The partition member 3 has a front mounting groove 31 at the upper part of the front edge and a rear mounting groove 32 near the rear of the lower edge. The front mounting groove 31 enters the rear from the front edge of the partition member 3. The rear mounting groove 32 is bent upward after entering upward from the lower edge of the partition member 3, and is formed in a substantially L shape.

In the procedure for attaching the partition member 3 to the pallet 2, first, the partition member 3 is advanced from the rear to the front, and the front mounting groove 31 is inserted into the mounting groove 26 of the front mounting shaft 24. Next, the rear portion 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 slightly pulled back to fit the rear mounting shaft 25 into the bent innermost portion of the rear mounting groove 32. As a result, the mounting posture of the partition member 3 is stabilized. Further, the procedure for removing the partition member 3 is substantially 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 attachment member such as a tool or a screw is required.

FIG. 2 illustrates three partition members 3 provided on the left side of the pallet 2. During operation, a larger number of partition members 3 are provided on the pallet 2 in parallel with each other. The maximum number of partition members 3 is equal to half of the maximum number of feeders 92 that can be equipped. By making the partition member 3 removable, the partition member 3 can be appropriately arranged according to the number and arrangement of the equipped feeders 92. Further, it is possible to use a plurality of types of reels having different thickness dimensions TR. A fixing pin 33 is provided so as to project in the horizontal direction at a substantially intermediate height toward 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).

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 be stopped (mounted). More specifically, the moving groove 4 has a large diameter mounting position 41 located at the upper part of the partition member 3 in the middle in the front-rear direction as a starting point. The moving groove 4 extends slightly upward from the large-diameter mounting position 41, immediately refracts and extends rearward, then sharply bends and extends forward and downward, and is mounted for small diameters. Reach position 42. Further, the moving groove 4 is bent sharply at the small diameter mounting position 42 and extends slightly diagonally upward to the rear, and further bent downward to reach the standby position 43 at the end point. The standby position 43 is located in front of the fixing pin 33.

As described above, the moving groove 4 connects a plurality of mounting positions (41, 42, 43) with a single stroke and has no branch point or intersection. Therefore, the decrease in the mechanical rigidity of the partition member 3 is suppressed, and the pin member 5 is prevented from falling off due to the deformation of the partition member 3. Further, since the large diameter mounting position 41 and the standby position 43 correspond to the descending ends (start point and end point) of the moving groove 4, the positions of the moved pin members 5 are stable.

The pin member 5 is provided so as to project horizontally from the right side surface of the partition member 3. The pin member 5 rotatably supports the center 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 fastening plate 54. The pin body 51 has a flange-shaped head portion 52 and a shaft portion 53. The diameter D1 of the head 52 is substantially 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 portion 52, and is 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 fastening plate 54 is a disk-shaped member. The diameter D3 of the fastening plate 54 is larger than the diameter D1 of the head 52.

When attaching the pin member 5 to the moving groove 4, the operator brings 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 operator fixes the fastening 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 operator can move the pin member 5 along the moving groove 4. Moreover, since the diameter D1 of the head 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 does not fall off from the moving groove 4.

Further, the head 52 of the pin body 51 passes through the center hole CH of the reel (RS, RL) at the very limit. Therefore, the operator can advance the reels (RS, RL) from the head portion 52 to the shaft portion 53 and mount the reels (RS, RL). The pin member 5 can move along the moving groove 4 even when the reels (RS, RL) are mounted. The reels (RS, RL) supported by the shaft portion 53 do not easily come off from the head portion 52, and rotate while maintaining the mounted state.

3. 3. Usage and operation of the reel holding device 1 Next, the usage and operation of the reel holding device 1 of the embodiment will be described with reference to FIGS. 5 to 9. When using the small diameter reel RS, the operator moves the pin member 5 supporting the center hole CH of the small diameter reel RS to the small diameter mounting position 42. As a result, the state shown in FIG. 5 is obtained. In FIG. 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.

In other words, the pin member 5 that supports the center hole CH of the small-diameter reel RS is positioned so that the upper end of the small-diameter reel RS is below the withdrawal path 94 of the feeder 92 when the diameter of the small-diameter reel RS is equal to or less than a predetermined value. Supports small diameter reel RS. Here, the predetermined value is 7 inches, which corresponds to the diameter of the small diameter reel RS. As a result, the labor of replacing the feeder 92 is reduced. If the small-diameter reel RS has entered the pull-out path 94, it is necessary to temporarily remove the small-diameter reel RS when replacing the feeder 92, which requires extra work.

Further, 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 in the direction of floating the small diameter reel RS. As a result, the levitation force F1 acts on the pin member 5 from the small diameter reel RS. The moving groove 4 is inclined and extends by an angle A and an angle B with respect to the direction of the levitation force F1. The angle A and the angle B are approximately 90 ° or 90 ° or more. Therefore, even if the levitation 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. Further, 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 about the small-diameter mounting position 42.

The small diameter reel RS mounting work and replacement work are performed as shown in FIG. That is, the operator moves the pin member 5 to the large diameter mounting position 41, bends the partition member 3, and mounts the small diameter reel RS on the pin member 5. Subsequently, the operator moves the pin member 5 that supports the small diameter reel RS to the small diameter mounting position 42 along the moving groove 4. Further, the operator moves the pin member 5 that supports the small diameter reel RS from the small diameter mounting position 42 to the large diameter mounting position 41, bends the partition member 3, and removes the small diameter reel RS.

In these operations, it is necessary to bend the partition member 3 to widen the gap between the partition member 3 and the side plate 23. Therefore, it is difficult to work at the small diameter mounting position 42 near the fixing portion (front side mounting groove 31 and rear side mounting groove 32) of the partition plate 3, and it is easy to work at the large diameter mounting position 41 away from the fixing portion. It becomes. As described above, the large-diameter mounting position 41 also serves as a replacement position for replacing the small-diameter reel RS. It should be noted that the small diameter reel RS can be replaced as long as it is in a high position close to the large diameter mounting position 41 of the moving groove 4, even if it is not necessarily the large diameter mounting position 41.

As shown in FIG. 2, the reel holding device 1 supports the small-diameter reel RS by using the pin member 5 on the front side of the right side surface of the partition member 3, and uses the fixing pin 33 on the rear side of the left side surface to support the small-diameter reel RS. The reel RS can be supported. The two small-diameter reels RS are used in combination with two feeders 92 mounted side by side. The carrier tape CT drawn out from the small-diameter reel RS is inserted into the feeder 92, allowing skewing up to about three times the thickness dimension TR of the reels (RS, RL). Further, since the small-diameter reel RS on the left side surface is located on the extension line behind the pull-out path 94, it does not hinder the replacement work of the feeder 92 regardless of the held height.

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 at the large-diameter mounting position 41. As a result, the state shown in FIG. 7 is obtained. In FIG. 7, a large diameter reel RL having a diameter of 15 inches is shown by a solid line, and a large diameter reel RL having a diameter of 13 inches is shown by a broken line.

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 in the direction of floating the large-diameter reel RL. As a result, the levitation force F2 acts on the pin member 5 from the large diameter reel RL. Since the levitation force F2 is generally directed forward, the pin member 5 hardly rises from the large diameter mounting position 41, and even if it rises, it does not move backward along the moving groove 4. Therefore, the large-diameter reel RL rotates stably about the large-diameter mounting position 41.

The large-diameter reel RL mounting work and replacement work can be performed at the large-diameter mounting position 41. That is, 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 supports the large-diameter reel RL by using the pin member 5 on the front side of the right side surface of the partition member 3, and uses the fixing pin 33 on the rear side of the left side surface. A large diameter reel RL can be supported. The two large-diameter reels RL are used in combination with two feeders 92 mounted side by side. Since the large-diameter reel RL on the left side is located on the extension line behind the pull-out path 94, it does not hinder the replacement work of the feeder 92 regardless of the held height. Further, the reel holding device 1 can also support reels (RS, RL) having different sizes on the right side surface and the left side surface of the partition member 3.

Further, as shown in FIG. 9, a holding method in which the large-diameter reel RL is supported by the outer peripheral support member 65 and the pin member 5 is not used is also possible. In this case, the operator moves the pin member 5 to the retracted position 43. According to this, when the large diameter reel RL is inserted between the two partition members 3, the pin member 5 does not get in the way. The outer circumference of the inserted large-diameter reel RL is supported by the outer peripheral support member 65 of the upper roller shaft 61, the middle roller shaft 63, and the rear roller shaft 64.

Further, the small diameter reel RS can also be supported by the outer peripheral support member 65 of the front roller shaft 62 and the middle roller shaft 63, or can be supported by the outer peripheral support member 65 of the middle roller shaft 63 and the rear roller shaft 64. In this case as well, the operator moves the pin member 5 to the retracted position 43. Since the pin member 5 is stationary at the retracted position 43, it does not hinder the rotation of the reel (RS, RL) or the withdrawal of the carrier tape CT. If the pin member 5 is misplaced in the middle position of the moving groove 4, the pin member 5 may gradually move during the operation of the component mounting machine 91, resulting in a malfunction.

In the reel holding device 1 of the embodiment, the pin member 5 that supports the center hole CH of the reel (RS, RL) is provided in the partition member 3 so as to be repositionable according to the difference in the 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 reels (RS, RL), for example, the labor of replacing the feeder 92 can be reduced.

4. Application and Modification of the Embodiment The fixing pin 33 on the left side surface of the partition member 3 may be omitted. The minimum configuration of the reel holding device 1 includes a pallet 2, one partition member 3 from which the fixing pin 33 is omitted, and one pin member 5 that moves the moving groove 4 of the partition member 3. Further, the partition member 3 may have two moving grooves 4, and a movable pin member 5 may be provided instead of the fixing pin 33 on the left side surface. Further, in order to correspond to a plurality of types of reels having different thickness dimensions TR, a plurality of types of partition members 3 having different lengths of the fixing pin 33 and the pin member 5 may be used in combination. Further, the purpose of changing the holding position of the reel (RS, RL) according to the reel diameter is to facilitate the replacement work of the reel (RS, RL) or to carry the carrier from the reel (RS, RL) to the feeder 92. This may be for adjusting the withdrawal path of the tape CT.

Further, the partition member 3 does not have a moving groove 4, and has 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 is attached to and detached from the mounting holes. It may be. However, in this configuration, there is a risk of losing the pin member 5, and in the embodiment, there is no risk of losing the pin member 5. Further, the movable pin member 5 supports the center hole CH of the reel (RS, RL), but even if it comes into contact with the outer periphery of the reel (RS, RL) to restrict the floating of the reel (RS, RL). good. The present embodiment can be applied and modified in various other ways.
