[Conventional technology]

Taping tapes containing chip-shaped electronic components are generally known. This taping tape is a long strip-like body consisting of a storage tape made of paper or plastic with grooves formed at regular intervals for storing chip-shaped electronic components, and a thin film-like material that is welded to the upper surface of the groove of the storage tape to cover it. It consists of a cover tape and is wound on a take-up reel and transported. The end of this wound taping tape,
In other words, the leader section is the leading end when the taping tape is pulled out from the take-up reel in the mounting device in the subsequent process, and is a band-shaped section where the cover tape extends from the end of the storage tape, and is stored in the taping tape. The cover tape is designed to be peeled off from the storage tape when removing the stored electronic components.

Conventionally, a winding device is used to wind the taping tape onto a take-up reel, and it includes a product guide to guide the taping tape to the take-up reel, and a leader part of the taping tape to prevent the taping tape from unraveling. There is a winding device equipped with a sticking mechanism that sticks the taping tape onto the winding circumferential surface of the taping tape with an adhesive tape. With this winding device, the taping tape is wound onto the take-up reel via the product guide, and the leader part of the taping tape passes through the product guide and is applied with adhesive tape around the winding area of the taping tape by the sticking mechanism. It was glued to the surface.

[The problem that the idea attempts to solve]

However, in the conventional product guide described above, when the leader part of the taping tape passes through the product guide, the leader part of the taping tape moves faster than the winding speed of the taping tape because the leader part of the taping tape is in the form of a thin film. may pass through the product guide, or the leader portion of the taping tape may wander or become trapped between the side plate of the take-up reel and the taping tape being taken up, causing the leader portion of the taping tape to There was a risk that the tape could not be adhered to the wound surface of the taping tape with the adhesive tape.

This invention was made in view of the above-mentioned problems, and it is an object of the present invention to provide a product guide for a winding device that allows the leader portion of a taping tape to be reliably attached to the winding circumferential surface of the taping tape.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention has a film-like cover tape welded to the top surface of the tape containing the parts, and a leader section of only the cover tape is formed at the end. a reel, a product guide rotatably supported so that the tip thereof appears between the reel side plates of the take-up reel, and which guides the transfer of the taping tape and follows the take-up circumferential surface; and a product guide in front of the product guide. The winding is provided on the winding reel and is rotatably supported so that the tip of the winding reel protrudes and retracts between the reel side plates of the winding reel, and is equipped with a sticking mechanism for pasting the leader part of the taping tape and the winding circumferential surface with an adhesive tape. In the winding device, a product guide of the winding device is provided with a contact body for suppressing leader vibration, which contacts the taping tape, at the tip end of the product guide.

[Effect]

According to this invention, the taping tape is wound onto the take-up reel via the product guide, and when the leader part of the taping tape passes through the product guide, the leader of the taping tape is Since the end part of the taping tape comes into contact with the abutting body, the end part of the taping tape passes through the product guide while the transition state is suppressed, that is, the deflection of the leader part is suppressed, and the tape is wound up with the adhesive tape by the sticking mechanism. It will be firmly attached to the surrounding surface.

〔Example〕

An embodiment of this invention will be described based on the drawings.

Figure 1 of the drawings is a side sectional view showing how the product guide is used, Figure 2 is a plan view of the product guide, Figure 3 is a front view of the product guide, and Figure 4 shows another embodiment of the product guide. 5 is a side view of the winding device, and FIG. 6 is a plan view showing the leader portion of the taping tape.

As shown in FIGS. 1 and 5, the winding device A
is the take-up reel 2 that winds the taping tape 1
, a feed-out mechanism 3 that feeds out the taping tape 1, a product guide 4 that guides the taping tape 1 from the feed-out mechanism 3 to the take-up reel 2, and a feed-out mechanism 3 that feeds out the taping tape 1, a product guide 4 that guides the taping tape 1 from the feed-out mechanism 3 to the take-up reel 2; A sticking mechanism 6 that sticks the leader part 1a to the winding peripheral surface 1b of the taping tape 1 with an adhesive tape 5, and a leader part 1a of the taping tape 1 provided between the delivery mechanism 3 and the product guide 4 are formed. It is composed of a forming mechanism 7.

As shown in FIG. 6, the taping tape 1 is welded to and covers a storage tape 1e in which grooves 1d for storing chip-shaped electronic components 1c are arranged at regular intervals, and the upper surface of the grooves 1d of the storage tape 1e. It consists of a thin film-like cover tape 1f.
The leader part 1a of the taping tape 1 is a band-shaped part where the cover tape 1f extends from the end of the storage tape 1e.The taping tape is cut by the forming mechanism 7, and the storage tape is further removed to form only the cover tape. be done.

As shown in FIG. 1, the take-up reel 2 consists of a reel core 2a and two side plates 2b, and is used to sequentially wind the taping tape 1 onto the outer peripheral surface of the reel core 2a. The center part of the reel core 2a is inserted into the output shaft S of the drive motor so that it can rotate freely. Furthermore, a groove 2c into which the tip 1g of the taping tape 1 is inserted is formed in the reel core 2a. In addition, take-up reel 2 in the drawing
is shown with the side plate 2b on one side omitted for convenience of explanation.

The product guide 4 has a passage 8 through which the taping tape 1 can pass, as shown in FIGS. 1 to 3.
It consists of a frame-shaped guide body 8 having a shape a formed therein, and an abutting body 9 provided at the distal end side of the guide body 8 and in contact with the upper surface of the leader portion 1a of the taping tape 1.

The guide body 8 is a hollow rectangular prism-shaped frame body, and both sides of the tip side are formed in a size that can be inserted between the side plates 2b of the take-up reel, and the tip portion is close to the reel core 2a of the take-up reel 2. It extends to the position. Further, the guide body can be freely rotated in the vertical direction using a rotation shaft 10 provided on the base end side of the guide body as a fulcrum. Furthermore,
A taping tape 1 is placed at the intermediate position of the guide body 8.
A detector 11 is attached to detect the leader portion 1a of the paper and activate the sticking mechanism 6.

The abutting body 9 is a plate spring whose width is slightly smaller than the width between the inner walls of the guide body 8 so that it can be inserted into the passage 8a, and is located in the cutout of the upper part of the distal end of the guide body 8. Attach the base end 9a to the upper center of the guide body 8 with a fixing device 12 such as a screw, and
b is always biased in the direction of contacting the bottom of the tip end of the guide body 8.

Therefore, the starting end 1g of the taping tape 1 that has entered the passage 8a from the proximal opening of the guide body 8 pushes up the distal end 9b of the abutting body 9 and exits from the distal opening of the guide body 8, and the taping tape The leader portion 1a of the taping tape 1 comes out while being held between the bottom of the tip end of the guide body 8 and the tip end portion 9b of the abutment body 9, and the leader portion 1a of the taping tape 1 is prevented from transitioning because it is thin and easily shakes. Guide body 8
will pass through. Further, since the width of the leader portion 1a of the taping tape 1 is narrower than the width of the storage tape 1e, and the leader portion 1a is closer to one side, the width of the abutting body 9 is also made slightly wider than the leader portion 1a, and one side of the leader portion 1a is narrower than the width of the storage tape 1e. It may be installed closer to the

The abutting body 9 is configured such that a biasing force acts in the direction in which the tip end 9b always contacts the bottom of the tip end of the guide body 8, but when the leader portion 1a of the taping tape 1 passes through the guide body 8, The above-mentioned biasing force may be applied only to this point. In this case, for example, the abutting body is a leaf spring that is always parallel to the bottom of the guide body 8, and an actuating body such as a micro cylinder is provided above the leaf spring, so that the leader part 1a of the taping tape 1 When passing through the guide body 8, the actuating body may be actuated to press the leaf spring, and the tip of the leaf spring may be moved in the direction of contacting the bottom of the tip portion of the guide body 8. After the leader portion 1a of the taping tape 1 has passed through the guide body 8, by operating the operating body in the opposite direction, the leaf spring will return to its original state, and the tip of the guide body 8 will be in an open state. . The operation of the actuating body may be performed by detecting the beginning of the leader portion 1a of the taping tape 1 with the detector 11, and the reverse operation may be performed using a timer or the like. Since the tip of the guide body 8 is thus open, even if the starting end 1g of the taping tape 1 is weak, it can be used because there is no need to push up the tip 9b of the abutting body 9.

In addition, the plate-shaped contact body 9 is made of a bidirectional shape memory element such as a shape memory alloy or a shape memory resin, and the bent state is memorized so that the tip contacts the bottom of the tip of the guide body 8 at high temperature. , the linear state may be memorized at a low temperature, and when the leader portion 1a of the taping tape passes through the guide body 8, the bidirectional shape memory element may be heated to be in a bent state. If the memory state is reversed, cooling or heating can be stopped.

A specific means using the above bidirectional shape memory element is shown in FIG. This abutting body 13 is formed of a plate-shaped bidirectional shape memory element 14 from the base end to the center, and a plate body 15 such as a leaf spring from the center to the tip, and a plate heater 16 is provided at the base end. , its base end and the plate heater are attached to the upper center of the guide body 8 with a fixing device 17 such as a screw. This bidirectional shape memory element 14 is stored in a state where the plate 15 on the tip side is bent so as to contact the bottom of the tip of the guide body 8 at a high temperature, and is stored in a straight state at a low temperature. .

When the starting end 1g of the taping tape 1 and the taping tape 1 are moving in the passage 8a of the guide body 8, the abutting body 13 holds the plate body 15 in a straight line state when the taping tape 1 is moving in the passage 8a of the guide body 8. When the leader portion 1a of the taping tape 1 passes through the guide body 8, the two-way shape memory element 14 is heated by the plate heater 16 so that the two-way shape memory element 14 is moved in two directions. The shape memory element 14 is bent and the plate 15 is moved to a position (indicated by the imaginary line in FIG. 4) where it contacts the bottom of the tip of the guide body 8. The leader part 1a of the taping tape 1 is the guide body 8
After passing through, the plate heater 16 is turned off, the bidirectional shape memory element 14 is brought into a straight state, and the plate 15 is returned to its original position. The power to the plate heater 16 may be turned on by detecting the beginning of the leader portion 1a of the taping tape 1 using the detector 11, and the power may be turned off by using a timer or the like. The tip side of the contact body 13 is connected to a plate body 15 such as a plate spring.
By doing this, even if the amount of displacement of the bidirectional shape memory element is unstable, the leader portion 1a of the taping tape 1 can be reliably held between the bottom of the tip of the guide body 8 and the tip of the plate 15, and the taping tape Since the leader portion 1a of taping tape 1 is not fixed, the leader portion 1a of the taping tape can pass through the guide body 8.

Furthermore, the plate-shaped contact body 9 may be a bimetal made by laminating two metals having different amounts of thermal expansion.

The pasting mechanism 6 includes an adhesive tape reel 6a that winds up the adhesive tape 5 pasted on a tape mount at equal intervals, and an arm 6b that is vertically movable for bending and peeling off the fed tape. It consists of a touch roller 6c that presses and sticks the adhesive tape 5 that protrudes to the distal end side of the arm body 6b, a feed roller 6d rotated by a tape feed motor, and a winding shaft 6e for the tape mount.

In the winding device A configured as described above, the taping tape 1 is wound up as follows.

First, the take-up reel 2 is installed in a predetermined position, and the product guide 4 is moved to the lower limit position (shown by the imaginary line in Fig. 1).
Make it. In the above state, the tip of the product guide 4 is located close to the groove 2c of the reel core 2a.

Next, by transporting the taping tape 1 by the operation of the feed roller 3a of the feeding mechanism 3, the starting end 1g of the taping tape 1 passes through the forming mechanism 7 and enters the passage 8a from the base end opening of the guide body 8.
pushes up the tip 9b of the contact body 9 and comes out from the tip opening of the guide body 8, and the groove 2c of the take-up reel 2
enter. When the take-up drive motor is activated to rotate the take-up reel 2 after entering, the starting end 1g of the taping tape 1 is bent from that position and wound around the reel core 2a to be taken up. In the above state, as the take-up reel 2 rotates and the taping tape 1 is transferred, the product guide 4, which is rotatable in a free state, rises.

Further, the taping tape 1 is wound up, and when a predetermined winding amount of the taping tape 1 is reached, the cutter 7a of the forming mechanism 7 is activated to cut the taping tape 1, cut out the storage tape 1e, and remove the taping tape 1. A leader portion 1a is formed. Leader portion 1a of the formed taping tape 1
are the bottom of the tip of the guide body 8 and the tip 9 of the contact body 9.
It moves while being held between When the leader portion 1a of this taping tape 1 passes the detector 11, the sticking mechanism 6 is activated to feed out the adhesive tape 5. The adhesive tape 5 is designed to start adhering before the leader part 1a of the taping tape 1 passes from the tip of the product guide 4, that is, while the leader part 1a is being held, and the leader part of the taping tape 1 It is pasted from 1a to the winding peripheral surface 1b. Winding is completed with the above operations.

This invention is not limited to the above-mentioned embodiment, and for example, the product guide includes a guide body 8 and a contact body 9 provided on the tip side of the guide body 8 and in contact with the lower surface of the leader portion 1a of the taping tape 1. It may consist of. Further, the contacting bodies may be two plates that contact the upper and lower surfaces of the leader portion 1a of the taping tape 1. Furthermore, the abutting body may protrude from the tip of the guide body.

[Effect of idea]

Since this invention is configured as described above, the leader part of the taping tape passes through the guide body while the transition state is suppressed, so that the leader part of the taping tape passes through the product guide faster than the winding speed of the taping tape. Since it is possible to prevent the leader portion from swaying as if dancing, it is possible to reliably attach the terminal end portion of the taping tape to the winding circumferential surface of the taping tape with the adhesive tape.
