Description

Reel holding device

Technical Field

The present specification relates to a tape reel holding device used in combination with a feeder equipped in a component mounter.

Background

A technique of performing a substrate-to-substrate operation on a substrate on which printed wiring is laid to mass-produce a substrate product has been widespread. As a typical example of a substrate working machine that performs a work on a substrate, there is a component mounting machine that performs a component mounting work. Many component mounting machines are equipped with feeders that pay out carrier tapes and supply components. A reel holding device that rotatably holds a reel on which a carrier tape is wound is also used. The tape reel holding device includes an integral type in which the feeder is integrally incorporated and a separate type independent from the feeder. Further, as a method of rotatably holding the reel, there are a center support method of supporting a center hole of the reel by a pin member and an outer periphery support method of supporting an outer periphery of the reel by a plurality of roller members. In the outer peripheral support system, care is required to prevent the reel from floating up when the carrier tape is pulled out. An example of such a tape tray 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 the reel holder, a center shaft that supports a center hole of the reel is slidably moved along a slide groove between a replacement position and an operating position. Accordingly, the reel can be moved together with the center shaft, and the replacement work of the reel is simple.

However, there is a need to change the holding position (operating position) of the reel depending on the size of the reel diameter without being limited to the configuration of patent document 1. For example, in a configuration in which a feeder is detachably provided at the rear of a component mounting machine and a tape reel holding device is disposed at the lower rear portion of the feeder, the tape reel may become an obstacle when the feeder is pulled out rearward. However, the small diameter reel can be held at a position below the withdrawal path of the feeder without being an obstacle. On the other hand, the large diameter reel is held at a position higher and larger in diameter than the small diameter reel. In addition, it is also conceivable to change the holding position of the reel depending on the reel diameter in order to facilitate the replacement work of the reel and to adjust the pull-out path of the carrier tape.

Disclosure of Invention

Therefore, the present specification addresses the problem of providing a reel holding device capable of changing the holding position of a reel in accordance with the reel diameter.

The present specification discloses a tape reel holding device which is used in combination with a feeder which is provided in a component mounting machine and which discharges a carrier tape containing a plurality of components to supply the components, and which holds a tape reel on which the carrier tape is wound so as to be rotatable, the tape reel holding device including: a support plate; a thin plate-shaped partition member provided upright on the pallet; and a pin member provided to the partition member so as to be capable of changing a position according to a difference in diameter of the reel, and supporting a center hole of the reel or contacting an outer periphery of the reel to restrict floating of the reel.

Effects of the invention

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 periphery of the reel is provided on the partition member so that the position thereof can be changed according to the diameter of the reel. Therefore, the holding position of the reel can be changed according to the reel diameter. As an effect of changing the holding position of the reel, for example, the trouble of replacing the feeder can be reduced.

Detailed Description

1. Structure of feeder 92 and relation between reel holding devices 1 according to embodiments

First, the configuration of the feeder 92 and the relationship between the reel holding devices 1 according to the embodiments will be described with reference to fig. 1 and 2. As shown by the left upper arrows in fig. 1 and 2, the directions of the component mounter 91, the feeder 92, and the tape reel holding device 1 that are common are determined. The reel holding device 1 of the embodiment is used in combination with a feeder 92 provided in a component mounter 91.

As shown in fig. 1 and 2, feeder shoe 93 is detachably provided at a substantially middle height of the rear portion of component mounting apparatus 91. Feeder tray 93 includes a substantially rectangular plane portion 931, an upright portion 935 standing from the front side of plane portion 931, and the like. The planar portion 931 has a plurality of insertion grooves 932 formed in a groove shape extending in the front-rear direction and arranged side by side in the width direction. A positioning portion 936 and a connector 937 are provided on the rear surface of the upright portion 935 at positions corresponding to the respective slots 932.

Feeder 92 is formed to be thin in the width direction, and is provided with positioning portion 926 and connector 927 on the front surface thereof. Feeder 92 is inserted and attached along a horizontal pull-out path 94 from a rear upright portion 935 of slot 932 toward the front. At this time, feeder 92 is positioned by the engagement of positioning portions (926, 936). Feeder 92 is supplied with power and connected for communication by fitting connectors 927 and 937 to each other. Fig. 2 illustrates a state in which every other slot 932 is equipped with 3 feeders 92. In operation, more feeders 92 are provided on the feeder pallet 93. Feeder 92 is pulled out and removed rearward along pull-out path 94.

Feeder 92 has a tape insertion port 921 at a position near the middle height of the rear side and a component supply position 922 at the upper part of 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 to the component supply position 922. The carrier tape CT is peeled off with its cover tape being released to the component supply position 922, and is in a state where component pickup is possible.

As shown in fig. 1, the reel holding device 1 is disposed at the rear lower portion of the feeder 92. Specifically, arm members 95 are provided at the left and right ends of the rear portion of feeder shoe 93. The arm member 95 is formed in an upright plate shape, and extends first to the horizontal rear, then extends obliquely in the rear-downward direction, and finally extends to the horizontal rear. Front side mounting bases 951 extending outward are provided at the inclined portions of the pair of right and left arm members 95. Rear mounting bases 952 projecting outward are provided at rear horizontal portions of the pair of left and right arm members 95. The reel holding device 1 is configured above the front mount 951 and the rear mount 952. The tape reel holding device 1 holds a tape Reel (RS) on which a carrier tape CT containing a plurality of components is wound so as to be rotatable, and feeds the carrier tape CT to a feeder 92.

2. Structure and function of reel holding device 1 according to the embodiment

Next, the structure and function of the reel holding device 1 according to the embodiment will be described with reference to fig. 1 to 4. The reel holding device 1 can hold a plurality of kinds of reels having different diameters. For example, there are small diameter reels RS having a diameter of 7 inches, large diameter reels RL (see fig. 7) having a diameter of 13 inches or 15 inches, and the types of reels are not limited to these. Fig. 1 illustrates two small radius discs RS, and fig. 2 illustrates 6 small radius discs RS. A center hole CH (see fig. 4) of a common hole DH that does not depend on the reel diameter is formed in the center of each reel (RS, RL).

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 palette 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 feeders 92. Therefore, the width dimension of the tape reel holding device 1 is slightly larger than the width dimension of the feeder palette 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-like member extending horizontally in the left-right direction, and is mounted and fixed to left and right rear attachment seats 952. A handle 22 is provided at the center in the left-right direction on the rear side of the bottom plate 21. The operator can collectively transfer the feeder shoe 93, the plurality of feeders 92, and the tape reel holding device 1 from the component mounter 91 to the replacement carriage (not shown) by pulling the handle 22 rearward.

The side plate 23 is a substantially right-angled triangular plate material. The first side of the side plate 23, which is sandwiched at right angles, extends from the front lower portion to the rear portion, the second side, which is sandwiched at right angles, extends from the front lower portion to the front upper portion, and the oblique side extends from the front upper portion to the rear portion. The pair of left and right side plates 23 have bottom surfaces 231 that are folded inward facing each other. The bottom surface 231 is fixed to the front side mount 951 by one screw 232 and to the rear side mount 952 by two screws 233. Thus, the pair of left and right side plates 23 are fixed perpendicularly to edges extending outward of the front mount 951 and the rear mount 952, as shown in fig. 2.

The front mounting shaft 24 is coupled to front upper portions of the pair of left and right side plates 23. The rear mounting shaft 25 is coupled to 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 extending in the left-right direction, and are provided with a plurality of circumferentially surrounding mounting grooves 26. The separation pitch PD of the plurality of mounting grooves 26 is greater than 2 times the thickness dimension TR of the reels (RS, RL).

The pallet 2 also has 4 sets of rollers (61, 62, 63, 64). The upper roller shaft 61 is positioned at the upper front portion of the pair of left and right side plates 23 and is coupled to the front mounting shaft 24 at a position rearward and upward. The front roller shaft 62 joins front lower portions of the pair of left and right side plates 23. The intermediate roller shaft 63 is coupled to a lower portion of the pair of left and right side plates 23 in the vicinity of the middle in the front-rear direction. The rear roller shaft 64 joins the rear portions of the pair of left and right side plates 23.

Each of the roller shafts (61, 62, 63, 64) has a plurality of outer circumferential support members 65. The outer circumferential support members 65 are formed as cylindrical roller members, and are rotatably held by roller shafts (61, 62, 63, 64). The number of the outer circumferential 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 circumferential support member 65 is slightly larger than the thickness dimension TR of the reels (RS, RL). The outer circumferential support member 65 can rotatably support the outer circumference of the reels (RS, RL). However, when the fixing pins 33 and the pin members 5 described later are used, the outer circumferential support member 65 is not used.

The partition member 3 is a thin plate-like member that is long in the front-rear direction. The partition member 3 is mounted upright in the mounting grooves 26 of the front mounting shaft 24 and the rear mounting 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 mounting groove 31 at an upper portion of the front edge and a rear mounting groove 32 near a rear portion of the lower edge. The front mounting groove 31 is formed rearward from the front edge of the partition member 3. The rear mounting groove 32 is formed in a substantially L shape by curving to the front side after entering upward from the lower edge of the partition member 3.

In the step of attaching the partition member 3 to the pallet 2, first, the partition member 3 is moved forward from the rear, and the front attachment groove 31 is inserted into the attachment groove 26 of the front attachment 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, and the rear mounting shaft 25 is fitted into the deepest bent portion of the rear mounting groove 32. This stabilizes the mounting posture of the partition member 3. The step of removing the partition member 3 is substantially reversed from the step of attaching. As described above, the step of attaching and detaching the partition member 3 is easy, and attachment members such as tools and screws are not required.

Fig. 2 illustrates three partition members 3 provided on the left side of the pallet 2. In operation, more separating elements 3 are arranged parallel to each other on the pallet 2. The maximum number of partition members 3 is equal to half of the maximum number of feeders 92 that can be equipped. By making partition member 3 detachable, partition member 3 can be appropriately arranged in accordance with the number and arrangement of feeders 92 provided. Further, a plurality of types of tape reels having different thickness dimensions TR can be used. The fixing pin 33 is provided to protrude in the horizontal direction at a substantially middle height near the rear portion of the left side surface of the partition member 3. The fixing pin 33 rotatably supports the center hole CH of the reels (RS, RL).

As shown in fig. 3, the partition member 3 has a moving groove 4 through which the pin member 5 moves. The moving groove 4 is formed at a plurality of attachment positions where the pin member 5 can be stopped (attached). Specifically, the moving groove 4 starts from a large-diameter mounting position 41 located at an upper position near the middle of the partition member 3 in the front-rear direction. The moving groove 4 extends slightly upward from the large-diameter mounting position 41, immediately bends and extends rearward, then bends at an acute angle and extends forward and downward, and reaches the small-diameter mounting position 42. The moving groove 4 is bent at an acute angle at the small-diameter mounting position 42, extends rearward and slightly obliquely upward, and is bent downward to reach a standby position 43 at an end point. The standby position 43 is located in front of the fixing pin 33.

As described above, the moving groove 4 connects the plurality of mounting positions (41, 42, 43) by one stroke, and has no branch point or intersection point. Therefore, the pin member 5 can be prevented from coming off due to the deformation of the partition member 3 while suppressing the reduction of the mechanical rigidity of the partition member 3. Further, the large diameter mounting position 41 and the standby position 43 correspond to the lowered ends (starting point and end point) of the moving bath 4, and therefore the position of the pin member 5 which has moved is stable.

The pin member 5 is provided to protrude in the horizontal direction from the right side surface of the partition member 3. The pin member 5 rotatably supports a center hole CH of the reels (RS, RL). As shown in fig. 4, the pin member 5 is composed of a pin body 51 and a stopper 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 bore diameter DH of the central bore 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 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 reels (RS, RL) and the thickness dimension TS of the partition member 3. The stopper plate 54 is a disk-shaped member. The diameter D3 of the stop plate 54 is greater than the diameter D1 of the head 52.

When the pin member 5 is attached to the moving groove 4, the operator brings the pin body 51 close 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 stopper plate 54 to the front end of the shaft portion 53. The diameter D2 of the shaft portion 53 is smaller than the groove width WC of the moving groove 4, so that the operator can move the pin member 5 along the moving groove 4. Further, since the diameter D1 of the head 52 and the diameter D3 of the stopper plate 54 are larger than the groove width WC of the moving groove 4, the pin member 5 does not fall off the moving groove 4.

The head 52 of the pin main body 51 can just penetrate the center hole CH of the reels (RS, RL). Therefore, the worker can mount the reels (RS, RL) by moving them from the head portion 52 to the shaft portion 53. The pin member 5 can move along the moving groove 4 even in a state where the reels (RS, RL) are attached. The reels (RS, RL) supported by the shaft portion 53 are not easily detached from the head portion 52, and rotate while maintaining the attached state.

3. Method for using tape reel holding device 1 and function thereof

Next, a method of using the reel holding device 1 according to the embodiment and an operation thereof will be described with reference to fig. 5 to 9. When the small diameter reel RS is used, the worker moves the pin member 5 supporting the center hole CH of the small diameter reel RS to the small diameter mounting position 42. This brings the state shown in fig. 5. 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 hinder the replacement work of the feeder 92.

In other words, when the diameter of the small diameter reel RS is equal to or smaller than the predetermined value, the pin member 5 that supports the center hole CH of the small diameter reel RS supports the small diameter reel RS at a position below the pull-out path 94 of the feeder 92. Here, the predetermined value is 7 inches corresponding to the diameter of the small diameter disc RS. This reduces the trouble of replacing feeder 92. If the small diameter reel RS enters the pull-out path 94, the small diameter reel RS needs to be temporarily removed during the replacement work of the feeder 92, which causes unnecessary trouble.

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 is pulled in a direction to float the small-diameter reel RS. Thereby, the pin member 5 is subjected to buoyancy force F1 from the small diameter disc RS. The moving groove 4 extends obliquely at an angle a and an angle B with respect to the direction of the upward buoyancy F1. The angles a and B are substantially 90 ° or more. Therefore, even if the upward buoyancy 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. 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 even under the influence of their own weight. Therefore, the small diameter disc RS rotates stably around the small diameter mounting position 42.

The mounting work and the replacement work of the small diameter reel RS are performed in the same manner as shown in fig. 6. 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 to the pin member 5. Next, the operator moves the pin member 5 supporting 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 supporting 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 enlarge the gap between the adjacent partition member 3 or side plate 23. Therefore, the work at the small-diameter mounting position 42 near the fixing portion (the front mounting groove 31 and the rear mounting groove 32) of the partition plate 3 is difficult, and the work at the large-diameter mounting position 41 apart from the fixing portion is easy. As described above, the large-diameter mounting position 41 also serves as a replacement position for replacing the small-diameter reel RS. The small-diameter reel RS can be replaced without being necessarily at the large-diameter mounting position 41, as long as it is in a high position range near the large-diameter mounting position 41 of the moving chute 4.

As shown in fig. 2, the reel holding device 1 can support the small diameter reel RS by using the pin member 5 near the front portion of the right side surface of the partition member 3 and can support the small diameter reel RS by using the fixing pin 33 near the rear portion of the left side surface. Two small diameter reels RS are used in combination with two feeders 92 equipped side by side. The carrier tape CT drawn out from the small-diameter reel RS is allowed to be obliquely moved to about 3 times the thickness TR of the reels (RS, RL) and inserted into the feeder 92. Further, the small diameter reel RS on the left side surface is located on the extension line behind the drawing path 94, and does not hinder the replacement work of the feeder 92 regardless of the held height.

Next, when the large diameter disk RL is used, the worker holds the pin member 5 supporting the center hole CH of the large diameter disk RL at the large diameter mounting position 41. This brings the state shown in fig. 7. In fig. 7, the large radius disk RL having a diameter of 15 inches is indicated by a solid line, and the large radius disk RL having a diameter of 13 inches is indicated 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 is pulled in a direction to float the large-diameter reel RL. Thereby, buoyancy F2 acts on the pin member 5 from the large radius disk RL. Since the upward buoyancy F2 is directed substantially forward, the pin member 5 hardly rises from the large-diameter mounting position 41, and if it rises, it does not move rearward along the moving groove 4. Therefore, the large-diameter reel RL rotates stably around the large-diameter mounting position 41.

The mounting work and the replacement work of the large-diameter reel RL can be performed at the large-diameter mounting position 41. In other words, the large-diameter mounting position 41 doubles 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 near the front portion of the right side surface of the partition member 3 using the pin member 5, and can support the large diameter reel RL near the rear portion of the left side surface using the fixing pin 33. Two large radius disks RL are used in combination with two feeders 92 equipped side by side. The large diameter disk RL on the left side surface is located on the extension line behind the pull-out path 94, and therefore does not hinder the replacement work of the feeder 92 regardless of the height to be maintained. The reel holding device 1 can also support reels (RS, RL) of different sizes on the right and left side surfaces of the partition member 3.

As shown in fig. 9, a holding method can be applied in which the large diameter disk RL is supported by the outer circumferential support member 65 and the pin member 5 is not used. In this case, the operator moves the pin member 5 to the retracted position 43. Accordingly, when the large radius disk RL is inserted between the two partition members 3, the pin member 5 does not become an obstacle. The outer periphery of the inserted large diameter disk RL is supported by the outer periphery supporting member 65 of the upper roller shaft 61, the middle roller shaft 63, and the rear roller shaft 64.

The small diameter reel RS may be supported by the outer circumferential support members 65 of the front roller shaft 62 and the middle roller shaft 63, or may be supported by the outer circumferential support members 65 of the middle roller shaft 63 and the rear roller shaft 64. In this case, the operator also moves the pin member 5 to the retracted position 43. Since the pin member 5 is stationary at the retracted position 43, the rotation of the reels (RS, RL) and the drawing out of the carrier tape CT are not hindered. If the pin member 5 is assumed to be located at a position midway in the moving groove 4, the pin member 5 may be moved slowly during the operation of the component mounting apparatus 91, which may cause a problem.

In the reel holding device 1 of the embodiment, the pin member 5 that supports the center hole CH of the reels (RS, RL) is provided on the partition member 3 so that the position thereof can be changed according to the difference in diameter of the reels (RS, RL). Therefore, the holding position of the reels (RS, RL) can be changed according to the reel diameter. As an effect of changing the holding position of the reels (RS, RL), for example, the trouble of replacing the feeder 92 can be reduced.

4. Applications and variants of the embodiments

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 is constituted by the pallet 2, one partition member 3 from which the fixing pin 33 is omitted, and one pin member 5 which 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 left-side fixing pin 33. 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 pins 33 and the pin members 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) and to adjust the pull-out path of the carrier tape CT from the reels (RS, RL) to the feeder 92.

The partition member 3 may be configured not to have the moving groove 4, but to have mounting holes at the large-diameter mounting position 41, the small-diameter mounting position 42, and the standby position 43, respectively, and to attach and detach the pin member 5 to and from the mounting holes. However, in this configuration, the pin member 5 may be lost, and the pin member 5 may not be lost in the embodiment. The movable pin member 5 supports the center hole CH of the reels (RS, RL), but may be in contact with the outer periphery of the reels (RS, RL) to restrict the floating of the reels (RS, RL). In addition to this, the present embodiment can realize various applications and modifications.
