BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a take-up reel for winding a tape and a tape take-up device having the take-up reel.

[0002]

2. Description of the Related Art Conventionally, various take-up reels used in an electronic component supply apparatus are known, and a cover tape (hereinafter also simply referred to as a "tape") for covering the surface of a component supply tape is known in the take-up reel. Being rolled up. A general structure of a take-up reel is a first flange integrally provided with a cylindrical winding frame around which a tape is wound, and another flange that is detachable with the winding frame sandwiched between the first flange. It consists of When winding the tape on the take-up reel, first, the winding start end of the tape is fixed to the outer peripheral surface of the winding frame using an adhesive tape, and then the tape is wound.

Further, the take-up reel constitutes a part of a tape take-up device used by being incorporated in an electronic component supplying device. An example of this tape winding device 10 is shown in FIG. The structure of this tape winding device 10 is a component supply comprising a base tape 12 in which electronic components are housed in series and a cover tape 14 releasably attached to the electronic component side of the base tape 12 to cover the electronic components. The tape feed mechanism that feeds the tape 16 to the front, and the component feed tape 16 fed from the tape feed mechanism to the cover tape 1
It is composed of a peeling unit 18 as a peeling mechanism for peeling the No. 4, the winding reel 20 described above, and a reel driving mechanism for rotating the winding reel 20. The tape feeding mechanism includes links 22a to 22c and a rotating claw 24.
And the gear 26 and the like, and the tooth portion of the gear 26 is the gear 2
With the rotation of 6, the base tape 1 of the component supply tape 16
2 Hook the lower surface and send it forward.

Further, the peeling portion 18 is formed in a flat claw shape, and is fed from the component supply tape 16 forward to the cover tape 14.
And the cover tape 14 is turned in the direction of arrow B. Further, 28 is a component take-out portion, which is formed in the opening. The cover tape 14 is peeled off at the peeling section 18, and the electronic component exposed on the base tape 12 is taken out by a take-out means (not shown). The base tape 12 from which the electronic components have been taken out is sent forward and discharged to the discharge position. The take-up reel 20 is provided on the shaft 30 so as to be rotatable together with the shaft 30 only in the counterclockwise direction. The first flange (back side) 3 on the base 32 side of the take-up reel 20
4 has, for example, a peripheral edge formed on a gear, and a cylindrical winding frame 36 around which the cover tape 14 is wound is integrally provided. Reference numeral 38 denotes a second flange (front side), which is detachable with the winding frame 36 sandwiched between the first flange.

The take-up reel 20 has a link 22d integrally formed with the link 22a and a tip end of the link 22e, which is axially mounted via a one-way clutch (not shown).
The gear 40 meshing with the flange 34 of the
It is composed of a spring 42 and the like stretched between d and the base 32, and is rotated by a reel drive mechanism that rotates the reel 20 counterclockwise by a predetermined amount.

Next, the operation will be described. In the state shown in FIG. 1, when the link 22a is rotated clockwise by a predetermined angle by means not shown, the link 22b is moved to the right, and the link 22c, the rotating claw 24 and the like are moved counterclockwise along the gear 26. Roll around. At this time, the gear 26 does not rotate.
When the link 22a is rotated clockwise, the link 22a

Since the flange 34 of the reel and the take-up reel reel 20 do not rotate clockwise, the gear 40 is
Roll around the edge of 4.

When the rotation of the link 22a by a predetermined angle is released, the links 22a, 22b, 22c, 22d are returned to their previous positions by the urging force of the spring 42. When the link 22c returns to the previous position, the rotation claw 24 rotates the gear 26, and the base tape 12 is fed forward for a predetermined length. By feeding the base tape 12, the component supply tape 16 is also fed, and the electronic components are fed to the component unloading section 28 one by one. As a result, the electronic component is taken out by a take-out means (not shown). As the component supply tape 16 is fed, the cover tape 14 whose tip is previously fixed to the winding frame 36 with an adhesive tape or the like is the peeling section 1
At 8 the tape is peeled off from the base tape 12 and turned in the direction of arrow B. At this time, a counterclockwise biasing force acts on the link 22e by the spring 44, and the gear 40 biases the first flange 34 to rotate counterclockwise. Since the take-up reel 20 and the shaft 30 can rotate counterclockwise, they rotate counterclockwise by a predetermined amount. By the rotation of the reel 20, the tape 14 is pulled in the direction of the arrow B while being tensioned, and is wound around the outer peripheral surface of the winding frame 36. When the cover tape 14 is wound around the outer circumference of the winding frame 36 in a tape reel shape by a predetermined amount, the tape winding device 10
Is stopped, the second flange 38 is removed from the first flange, and the cover tape 14 wound around the winding frame 36 is removed.

[0008]

However, the conventional take-up reel described above has the following problems. The tape 14 is pulled while being applied with tension, and is wound around the outer peripheral surface of the winding frame 36.
Rolled up to 6 very tightly. Therefore, the cover tape 14 in a tape reel shape after winding is wound on the winding frame 36.
Therefore, there is a problem that the work efficiency is lowered because it is difficult to remove and it takes time. Also, the cover tape 14
It is necessary to fix the winding start end of the tape 14 to the winding frame 36 with adhesive tape or the like in advance before starting the winding of the tape, and each time the adhesive tape is prepared and the winding start end is attached with the adhesive tape. It was annoying. Therefore,
The present invention has been made to solve the above problems, and an object of the present invention is to easily fix a winding start end of a tape and to easily remove a tape wound in a tape reel form from a winding frame. An object of the present invention is to provide a possible take-up reel and a tape take-up device using the take-up reel.

[0009]

In order to solve the above problems, the present invention has the following constitution. That is, the take-up reel according to the present invention includes a first flange provided with a cylindrical winding frame and a second flange that is detachable with the winding frame sandwiched between the first flange. Be equipped with
In a take-up reel capable of winding a tape around the winding frame, at least a part of the winding frame is formed into an elastic piece having an arc-shaped cross section that is elastically deformable in a radial direction of the winding frame, and the outer periphery of the elastic piece is The winding start end of the tape is insertable, and a cutout portion that holds the winding start end when the elastic piece is elastically deformed in the outer peripheral direction is provided over the entire width of the winding frame. The second flange is characterized in that it is provided with a pressing unit that is located inside the winding frame when attached to the first flange and that presses the elastic piece in the outer peripheral direction. With this configuration, when the winding start end portion of the tape is inserted into the cutout portion, when the elastic piece is elastically deformed in the outer peripheral direction, the winding start end portion is clamped by the cutout portion and can be fixed to the winding frame. it can.

Further, if a through hole is formed inside the elastic piece along the width direction of the winding frame, and the notch is provided so as to extend from the outer circumference to the through hole, the elastic piece is formed. When is elastically deformed in the inner peripheral direction, it is easy to bend at the cutout portion and the through hole portion, and the winding start end portion is easily inserted into the cutout portion. Further, when the elastic piece is elastically deformed in the outer peripheral direction, the winding start end can be reliably sandwiched between the facing surfaces of the cutout.

Further, one of the first flange and the second flange is provided with an engaging claw, and the other of the first flange and the second flange is provided with a second portion with respect to the first flange. The engaging claws can be inserted when the flanges of (1) and (2) are brought close to each other in accordance with the extraction position, and the second flange is rotated from the extraction position with respect to the first flange to be the attachment position. In this case, the engaging claw engages with the edge portion, and the first flange is provided with an engaging hole in which the second flange is attached in a non-removable manner. If the elastic piece is pressed in the outer peripheral direction when the attachment position is reached with respect to the first flange,
When the first flange and the second flange are combined, the elastic piece is pressed in the outer peripheral direction by the pressing means, the diameter of the winding frame is expanded at least partially, and the tape is wound in this state. Further, since the elastic piece is deformed in the outer peripheral direction, the winding start end portion of the tape inserted into the cutout portion is clamped. Then, when the second flange is rotated to the withdrawal position with respect to the first flange after the winding is finished, the pressing of the elastic piece in the outer peripheral direction is released and the elastic piece is deformed in the inner peripheral direction, Since the diameter of the winding frame is partially reduced, the wound reel-shaped tape is easier to remove than the winding frame.

Further, a tape for feeding a component forward comprising a base tape in which electronic components are housed in series and a cover tape detachably attached to the electronic component side of the base tape to cover the electronic components is sent forward. A feeding mechanism, a peeling mechanism for peeling the cover tape from the component supply tape fed by the tape feeding mechanism, the winding reel according to the present invention capable of winding the cover tape, and the winding reel. If the tape winding device is configured with the reel drive mechanism for rotating, the winding start end of the cover tape can be easily attached to the winding reel,
In addition, it is possible to realize a tape winding device in which the cover tape can be easily removed after winding.

[0013]

[Operation] The operation will be described. At least a part of the winding frame provided on the first flange that constitutes the take-up reel is formed as an elastic piece having an arc-shaped cross section that is elastically deformable in the radial direction of the winding frame, and the tape around the outer circumference of the elastic piece. A cutout into which the winding start end can be inserted is provided over the entire width of the winding frame. On the other hand, the second flange attached to the first flange is provided with a pressing unit that is located inside the winding frame when attached to the first flange and presses the elastic piece in the outer peripheral direction. Therefore, if the second flange is attached to the first flange after inserting the winding start end of the tape into the notch, the pressing means elastically deforms the elastic piece in the outer peripheral direction, so that the opposing surfaces of the notch are They are brought into close contact with each other and the winding start end is clamped. Further, the tape is wound with the elastic piece of the winding frame deformed in the outer peripheral direction and the winding frame is expanded in diameter, and if the second flange is removed from the first flange to remove the wound tape, the tape is elastic. Since the piece returns to the original position and the diameter of the winding frame is reduced, a gap is created between the inner diameter of the wound tape and the winding frame, and the tape can be easily removed.

Also in a tape winding device incorporated in an electronic component mounting device or the like, the winding start end portion of the cover tape can be easily fixed by the notch portion provided in the elastic piece, and the cover tape is attached to the outer periphery of the winding ring. Even if the tape is tightly wound around the reel, if the second flange is removed from the first flange, the elastic piece returns to its original position and the reel is reduced in diameter. A gap is created between the tape and the tape and the tape can be easily removed.

It is composed of a spring 42 and the like stretched between 2d and the base 32, and rotates the reel 20 counterclockwise by a predetermined amount. The reel drive mechanism and the tape feed mechanism are not limited to the present embodiment, and particularly the reel drive mechanism does not depend on the gear 40 or the spring 42 stretched between the link 22d and the base 32. As a configuration, the outer edge of the first flange 34 may not have a tooth portion.

Next, the structure of the take-up reel 46, which is a characteristic part of the present invention, will be described in detail with reference to FIGS. At least a part of the cylindrical winding frame 48 provided on the first flange 34 is attached to, for example, a synthetic resin material (6.6 as an example) on the elastic piece 50 having an arc-shaped cross section that is elastically deformable in the radial direction of the winding frame 48. Nylon). In this embodiment, as shown in FIG. 2, the elastic piece 50 is formed in a semi-arcuate shape, and the two elastic pieces 50 are combined to form the cylindrical winding frame 48. As shown in FIG. 3, there is only one, and the structure may be formed on a part of the reel 48, or the reel 48 may be formed with three or more reels. As shown in FIG. 2, the two elastic pieces 50 are fixed to the first flange 34 by using the pins 52 at the end portions in the clockwise direction, and the radius of the winding frame 48 at the end portions in the counterclockwise direction, as an example. It can be elastically deformed in any direction. Further, an arc-shaped extending portion 54 extending along the circumference of the winding frame 48 is formed on the end side in the clockwise direction further than the fixed portion of each elastic piece 50 by the pin 52, and one elastic portion is formed. The distal end of the piece 50 in the clockwise direction is located inside the other extending portion 54.
In addition, the overlapping state of the extending portion 54 and the tip end portion in the clockwise direction is maintained even when the elastic piece 50 is elastically deformed in the outer peripheral direction by the pressing means described later. The elastic piece 50
The end portion side in the counterclockwise direction may be fixed to the first flange 34 using the pin 52, and the end portion side in the clockwise direction may be elastically deformable in the radial direction of the winding frame 48.

Further, the winding start end of the cover tape 14 can be inserted into the outer periphery of the elastic piece 50, and when the elastic piece 50 elastically deforms in the outer peripheral direction and comes into contact with the extending portion 54. The notch 56 that holds the winding start end of the tape 14 in close contact with each other on the opposite surface is the winding frame 48, that is, the elastic piece 50.
Is provided over the entire width of. Also, the notch 56
The elastically deformable counterclockwise end portion is provided at the root portion (near the fixing portion by the pin 52), and the amount of elastic deformation in the radial direction on the end portion side is also increased.
Further, in this embodiment, a through hole 58 extending in the width direction of the winding frame 48 (the front-rear direction in FIGS. 2, 3, and 7) is formed inside the base portion of the elastic piece 50, and the notch 56 is formed. It is provided so as to reach from the outer periphery to the through hole 58. As a result, the thin portion C between the through hole 58 and the inner periphery of the elastic piece 50 serves as a fulcrum for elastically deforming the elastic piece 50, so that the counterclockwise end portion side of the elastic piece 50 is further elastically deformed. In addition, the opposing surfaces of the cutout portion 56 can evenly adhere to each other when the elastic piece 50 is elastically deformed in the outer peripheral direction, and the winding start end portion of the cover tape 14 can be reliably held. . When the elastic force of the elastic piece 50 is strong, the notch 56 may be provided without providing the through hole 58. However, the adhesiveness between the opposing surfaces of the notch 56, particularly the elastic piece 50. It is difficult to secure the adhesion near the outer periphery of the tape, and it is necessary to insert the tip of the tape 14 into the notch 56. Further, as shown in FIG. 4, a sandwiching projection 60 is provided on at least one of the facing surfaces (particularly in the vicinity of the outer periphery) of the notch 56 to reduce the contact area with the end portion of the tape 14 to increase the sandwiching pressure and ensure the sandwiching. It may be configured to be able to

Further, as shown in FIG. 5, the second flange 38 is located inside the winding frame 48 when attached to the first flange 34, and presses the elastic piece 50 in the outer peripheral direction. 62 is provided. The pressing means 62 is formed, for example, in a ring shape, and a pressing protrusion 64 projecting in the outer peripheral direction of the second flange 38 is formed on the outer peripheral surface of the pressing means 62 as a center of rotation of the second flange 38 (a center of rotation of the reel 48). The same) is provided as the center, and four are provided at intervals of 90 degrees. Further, from the pressing projection 64, a tip is formed in a column shape with an enlarged diameter, and an engaging projection 68 having a function as an engaging claw 66 is formed in a direction perpendicular to the second flange 38 at the enlarged tip. It is projected.

The second flange 38 is detachable with the winding frame 48 sandwiched between the first flange 34 and the detachable structure. The first flange 34 is formed with four engagement holes 70 that extend in the circumferential direction corresponding to the engagement protrusions 68. As an example, only the end portion side of the engagement hole 70 in the counterclockwise direction is formed. The neck 72 of the engaging projection 68 is formed to have a size such that the engaging claw 66 of the engaging projection 68 can be inserted therein, and the other portion of the engaging hole 70 has a smaller diameter than the engaging claw 66.
It is opened to a width that matches the diameter of. The number of the engaging projections 68 and the engaging holes 70 described above is not limited to four,
It may be two, three, five or the like. Also, the engaging protrusion 6
The shapes of 8 and the engaging hole 70 are not limited to the present embodiment, and may be realized by other shapes.

With this structure, the second flange 38 is pulled out of the first flange 34 (the engaging projection 68 is located at the end of the engaging hole 70 in the counterclockwise direction).
Then, the engaging claw 66 of the engaging protrusion 68 is inserted into the engaging hole 70. After that, the second flange 3
When 8 is rotated clockwise with respect to the first flange 34, the neck 72 of the engaging projection 68 moves in the engaging hole 70, and the engaging claw 66 engages with the edge of the engaging hole 70. It is located in the mating attachment position. Therefore, the second flange 38 is permanently attached to the first flange 34. When removing the second flange 38 from the first flange 34, on the contrary, the second flange 38 is rotated counterclockwise,
It suffices to move the engagement protrusion 68 toward the end portion of the engagement hole 70 in the counterclockwise direction to separate the second flange 38 from the first flange 34. Further, only the clockwise end portion side of the engagement hole 70 is opened so that the engagement claw 66 of the engagement projection 68 can be inserted, and the other portion of the engagement hole 70 is engaged with the engagement claw 66. The engagement protrusion 68 formed to have a smaller diameter may be opened to a width corresponding to the diameter of the neck portion 72. In this case, the second flange 38 is arranged counterclockwise with respect to the first flange 34. When rotated, the neck portion 72 of the engaging protrusion 68 is engaged with the engaging hole 70.
Moving inside, the engagement claw 66 is located at the attachment position where it engages with the edge of the engagement hole 70, and the second flange 38 is attached to the first flange 34. On the contrary, the second flange 38 is rotated in the clockwise direction so that the engaging projection 68 is engaged with the engaging hole 70.
The second flange 38 can be detached from the first flange 34 by moving the second flange 38 to the end side in the clockwise direction.

The shape of the inner peripheral surface of the elastic piece 50 is the second
When the flange 38 is in the withdrawal position with respect to the first flange 34, the pressing protrusion 64 is formed so as to be recessed in the outer peripheral direction so as not to contact the inner peripheral surface, and from there, the engaging hole 70 is formed. Is formed on the slope so as to gradually become thicker in the inner peripheral direction along the extending direction (circumferential direction). Accordingly, when the second flange 38 is rotated clockwise with respect to the first flange 34, the pressing protrusion 64 comes into contact with the inner peripheral surface of the elastic piece 50 formed on the inclined surface, and the elastic piece 5
The outer diameter of the winding frame 48 is expanded by pressing 0 toward the outer peripheral direction.

Next, a method of using the take-up reel 46 will be described. First, with the second flange 38 removed from the first flange 34, the winding start end of the cover tape 14 to be wound around the winding frame 48 is
The elastic piece 50 is inserted into the cutout portion 56. At the time of insertion, if the elastic piece 50 is forcibly elastically deformed in the inner circumferential direction against its elastic force, the notch 56 opens, so that the winding start end of the cover tape 14 is inserted into the notch 56. Can be inserted. When the forced elastic deformation is released, the elastic piece 50 returns to its original position by its own elastic force, and the opposing surfaces of the notch 56 are brought into close contact with each other, and the winding start end of the tape 14 is clamped. It Next, the second flange 38
Is brought closer to the first flange 34 in accordance with the extraction position, and the tip of the engagement projection 68 is inserted into the engagement hole 70. Then, the second flange 38 is attached to the first flange 3
4 to rotate to the attachment position shown in FIG. As a result, the second flange 38 is attached to the first flange 34 irremovably.

Further, by setting the second flange 38 to the attachment position with respect to the first flange 34, each elastic piece 5
Since 0 is elastically deformed in the outer peripheral direction by the pressing protrusion 64,
The outer diameter of the winding frame 48 itself formed by the elastic piece 50 increases. Further, the deformation of the elastic piece 50 in the outer peripheral direction further strengthens the clamping force at the winding start end of the tape 14 in the notch 56. Further, the middle portion of each elastic piece 50 and the counterclockwise end portion of each elastic piece 50 that overlaps with each extending portion 54 are supported from the inside by four pressing protrusions 64 so as not to be elastically deformed in the inner peripheral direction. Since the tape 14 is pulled, the tape 14 is pulled while being tensioned, and the reel 36
Even if it is very tightly wound around the outer peripheral surface of the elastic piece 5
It is possible to prevent 0 from being elastically deformed in the inner circumferential direction to reduce the diameter of the winding frame 48. Then cover tape 14
Tape 1 that has been wound into a tape reel
When removing 4 from the winding frame 36, the second flange 38 is rotated counterclockwise and removed from the first flange 34. Thereby, each elastic piece 50 that constitutes the winding frame 48
Is released from the pressing protrusion 64 in the outer peripheral direction,
Since the elastic member deforms and returns to the original position in the inner circumferential direction, the outer diameter of the winding frame 48 itself is also reduced. Therefore, a gap is formed between the tape reel and the innermost circumference of the cover tape 14, and the cover tape 14 can be easily removed from the winding frame 48. Further, the winding start end portion of the cover tape 14 is easily removed by forcibly elastically deforming the elastic piece 50 into which the winding start end portion is inserted further in the inner peripheral direction and releasing the sandwiched state.

Further, in the above-mentioned embodiment, the elastic piece 50 is
Even if the pressing means 62 does not press the outer peripheral direction,
Although the opposing surface of the cutout portion 56 is in close contact with itself due to its own elastic force, when the cutout portion 56 is formed in a groove shape and is not pressed by the pressing means 62 in the outer peripheral direction, the winding start end of the cover tape 14 Part can be inserted, and pressing means 6
It is also possible to adopt a structure in which the opposing surfaces of the notch 56 are brought into close contact with each other and the winding start end is clamped only after being pressed in the outer peripheral direction by 2. With this configuration, when the second flange 38 is rotated to the extraction position with respect to the first flange 34 after the winding is completed, the pressing of the elastic piece 50 by the pressing means 62 in the outer peripheral direction is released and the elastic piece 50 is elastic. The piece 50 is deformed inward,
The outer diameter of the winding frame 48 is partially reduced, and at the same time, the nipping by the notch portion 56 at the winding start end is released, so that the cover tape 14 wound in a reel shape becomes easier to remove from the winding frame 48.

As described above, various preferred embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments, and many modifications can be made without departing from the spirit of the invention. Of course.

[0027]

When the take-up reel according to the present invention is used, the winding start end of the tape can be inserted into the cutout portion provided in the elastic piece so as to be clamped by the cutout portion and fixed to the winding frame. Unlike the conventional example, it is not necessary to fix it to the winding frame with an adhesive tape or the like, which saves labor. Further, since a part of the winding frame is formed into an elastic piece that is elastically deformable in the radial direction, by elastically deforming the elastic piece in the inner circumferential direction when removing the tape wound on the winding frame. The outer diameter of the reel can be reduced, and the tape can be easily removed.
In addition, a through hole is provided inside the elastic piece along the width direction of the winding frame, and the notch is provided so as to extend from the outer periphery of the elastic piece to the through hole, so that when the elastic piece is elastically deformed in the inner peripheral direction. The cutout portion and the through-hole portion are easily bent, and the winding start end portion is easily inserted into the cutout portion. Further, since the facing surface of the notch for holding the tape is formed only in the vicinity of the outer periphery of the elastic piece, the facing surfaces are easily brought into close contact with each other, and the tape can be securely held. In addition, the first flange and the second flange are configured to be detachable by using the engaging claw and the engaging hole, and the second flange is rotated from the pull-out position with respect to the first flange. If the pressing means is configured to press the elastic piece in the outer peripheral direction when the engaging claw is in the attachment position where it engages with the edge portion, when the first flange and the second flange are combined, the elastic piece will not move. The tape is pressed in the outer peripheral direction by the pressing means, and the gripping force of the winding start end of the tape by the notch can be further increased. Further, since the elastic piece elastically deforms in the outer peripheral direction, at least a part of the diameter of the winding frame is expanded, and the tape is wound in this state. Therefore, after the winding is completed, the second flange is rotated. When the elastic piece is removed from the first flange and the pressing of the elastic piece in the outer peripheral direction is released, the elastic piece is deformed inward by the elastic force of itself and the diameter of the winding frame is partially reduced. Diameter. Therefore, a gap is created between the innermost circumference of the tape wound in the tape reel shape and the outer circumference of the winding frame, and the wound reel tape can be easily removed from the winding frame. Further, if a tape winding device is configured using the winding reel according to the present invention, the tape winding start end can be easily attached to the winding reel, and the tape can be easily removed after winding. It has a remarkable effect that a taker can be realized.
