10, the shutter 9 is moved in the forward direction in the direction indicated by the arrow (b), and the shutter 9 is moved in synchronization with the return operation of the operation lever 26 as shown in FIG.
(B), a backward movement is performed in the direction indicated by the arrow (c). Then, the component sending mechanism 11 sends out the taping electronic component 3 by a certain distance by the rotation of the wheel 28 when the shutter 9 moves forward.

The cover tape take-up reel 13 has a cover tape 20 pulled out from the cover tape draw-out port 9c of the shutter 9 wound thereon. When the cover tape 20 is rotated in the direction of arrow (d) in FIG. Take-up.

As shown in FIG. 11, the take-up reel drive mechanism 15 includes a take-up lever 30 integrally provided with the operation lever 26, and the take-up lever 30 takes up the cover tape take-up reel 13. Spring 32 biased in the direction

The one-way clutch 34 does not transmit the rotation to the cover tape take-up reel 13 when the take-up lever 30 swings in the direction of pulling the tension coil spring 32 in conjunction with the pressing operation of the operation lever 26.

With the above configuration, the take-up reel drive mechanism 1
Reference numeral 5 denotes the take-up lever 30 swinging around the axis of the cover tape take-up reel 13 in conjunction with the operation lever 26, and swinging of the take-up lever 30 in the take-up direction of the cover tape take-up reel 13. Only at the time, the rotation torque is transmitted to the cover tape take-up reel 13 by the urging force of the take-up spring 32, and at this time, the cover tape 20 is separated from the carrier tape 21 by the tension T acting on the cover tape 20 from the reel.

[0017]

By the way, in the above-mentioned electronic component supply device 1, when the supply of components is repeated, the winding diameter of the cover tape 20 on the cover tape winding reel 13 increases accordingly. Then, the rotation angle of the cover tape take-up reel 13 necessary for winding the cover tape 20 having a certain length gradually decreases as the diameter of the cover tape 20 wound around the cover tape take-up reel 13 increases. .

However, when the operation lever 26 is pressed, the take-up reel drive mechanism 15 of the electronic component supply device 1 extends the take-up spring 32 by the take-up lever 30 that swings integrally with the operation lever 26. When the operation lever 26 returns,
The cover tape take-up reel 13 is driven to rotate in the take-up direction by the restoring force of the extended take-up spring 32. Rotational torque acts on the cover tape take-up reel 13 until the take-up lever 30 returns to the initial position. I do.

Therefore, the cover tape take-up reel 13
When the winding diameter of the cover tape 20 in FIG. 13 increases, the winding lever 30 does not return to the initial position even if the winding by the fixed feed amount by the component sending mechanism 11 is completed.
As shown in the drawing, the take-up spring 3 of the take-up reel drive mechanism 15
The state where the tension T in the winding direction acts on the cover tape 20 by the spring force of 2 continues. This remaining tension T
Works as a force F for pulling the taping electronic component 3 in the feed direction, causing excessive feed of the taping electronic component 3 as shown in FIG. As shown in FIG. 2B, there is a problem that a shift L of the suction position of the electronic component 22 by the component take-out mechanism 17 occurs.

Therefore, an object of the present invention is to solve the above-mentioned problem, and even if the diameter of the cover tape on the cover tape take-up reel is increased, after the winding amount corresponding to the feed amount by the component sending mechanism is increased, Extra tension does not act on the cover tape due to the spring force used for take-up, and therefore, the taping electronic component resulting from the extra tension acting on the cover tape after winding up by the component sending mechanism for the amount of feed. It is an object of the present invention to provide an electronic component supply device capable of reliably preventing overfeeding and improving the feeding accuracy of the taping electronic component, thereby improving the reliability of the component supply operation.

[0021]

The above object of the present invention is achieved by the following constitution.

A shutter provided with a carrier pressing portion for pressing the upper surface of the carrier tape from which the tape has been removed, a component outlet for taking out an electronic component from the carrier tape, and a reciprocating motion of the shutter by operating means, and a forward movement of the shutter. Sometimes a component sending mechanism that sends the taping electronic component a fixed distance, A cover tape winding reel around which a cover tape pulled out from a cover tape drawing-out opening of the shutter is wound, and a spring force that generates a rotational torque in a winding direction on the cover tape winding reel when the shutter returns. A take-up reel drive mechanism for causing the cover tape to be peeled off from the carrier tape by the tension acting on the cover tape from the reel while being wound around the reel; An electronic component supply device having a component take-out mechanism for taking out the tape, wherein the take-up reel drive mechanism takes up the cover tape take-up reel by the action of the spring force each time the shutter returns. Is always regulated by the component feed amount by the component feed mechanism. A take-up amount control means for reducing the rotation angle of the take-up reel due to the action of the spring force of the take-up reel drive mechanism at the time of return movement of the cover taper as the winding diameter of the cover tape increases. Electronic component supply device.

A take-up lever capable of transmitting a rotational torque to the cover tape take-up reel only when moving, and a take-up spring for urging the take-up lever in a take-up direction of the reel. The take-up amount control means includes a winding diameter detecting arm that rotates according to the winding diameter of the cover tape on the cover tape winding reel, and the winding diameter detecting arm is provided integrally with the winding diameter detecting arm in the winding direction of the winding lever. And a stopper lever for adjusting a displacement limit position of the electronic component according to an increase in the winding diameter.

[0023]

According to the above construction, the amount by which the take-up reel drive mechanism rotates the cover tape take-up reel in the take-up direction by the spring force depends on the increase in the cover tape take-up diameter of the cover tape take-up reel. The tape length is gradually reduced, and the length of the tape that the take-up reel drive mechanism takes up on the cover tape take-up reel by the action of the spring force at every one return operation of the shutter is always restricted to the component feed amount by the component feed mechanism. Is done.

Therefore, even if the winding diameter of the cover tape on the cover tape take-up reel increases, after the winding of the feed amount by the component sending mechanism, extra tension is applied to the cover tape by the spring force used for winding. Therefore, excessive feeding of the taping electronic component due to excess tension acting on the cover tape after winding up by an amount corresponding to the feed amount by the component sending mechanism can be reliably prevented, and the taping electronic component can be reliably prevented. The reliability of the component supply operation can be improved by improving the component feeding accuracy.

According to the above configuration, the range of the spring force acting on the take-up reel drive mechanism can be easily adjusted by adding a single component integrating the take-up diameter detection arm and the stopper lever. Can be controlled in accordance with the winding diameter in, and the object can be achieved at low cost.

The electronic component supply device 1 shown in FIGS. 5 to 12 is provided with a winding amount control means 43.
Configurations other than 3 are the same as those of the electronic component supply device 1. The same components as those of the electronic component supply device 1 are denoted by the same reference numerals, and description thereof will be omitted or simplified.

In the electronic component supply device 41 of this embodiment, the cover tape 20 peeled off from the taping electronic component 3 is replaced with the cover tape when the operation lever 26 serving as the operating means returns (ie, when the shutter 9 returns). The take-up reel drive mechanism 15 that makes the take-up reel 13 take up
It has the same configuration as the electronic component supply device 1, and has a take-up lever 30 integrated with the operation lever 26 and biases the take-up lever 30 in the take-up direction of the cover tape take-up reel 13. The take-up spring 32 and the take-up lever 3
And a one-way clutch that couples the rotation axis of the take-up lever 30 and the rotation axis of the cover tape take-up reel 13 only when 0 rotates in the take-up direction of the cover tape take-up reel 13. is there. In the case of this example, the winding spring 32 is a tension coil spring.

The one-way clutch 34 does not transmit the rotation to the cover tape take-up reel 13 when the take-up lever 30 swings in the direction of pulling the tension coil spring 32 in conjunction with the pressing operation of the operation lever 26.

The take-up amount control means 43 additionally provided in the present embodiment comprises a roller 45 which comes into contact with the outermost periphery of the cover tape 20 wound on the cover tape take-up reel 13.
Is mounted on the distal end and the proximal end is rotatable.
And a stopper lever 49 which is integrally provided with the winding diameter detection arm 47 and adjusts the displacement limit position of the winding lever 30 in the winding direction in accordance with an increase in the winding diameter. And the cover tape 20 in which the roller 45 is wound on the cover tape winding reel 13.
And a lever urging spring 51 that urges the outermost peripheral portion to maintain a state of contact with the outermost periphery.

With the above arrangement, the winding amount control means 43
As shown in FIGS. 3A and 3B, when the winding diameter of the cover tape 20 on the cover tape winding reel 13 is small, a large movable space is provided between the winding lever 30 and the stopper lever 49. L1 is secured. However, as shown in FIGS. 4A and 4B, as the winding diameter of the cover tape 20 increases, the movable space between the winding lever 30 and the stopper lever 49 decreases. As described above, when the winding diameter detection arm 47 rotates according to the winding diameter of the cover tape 20 on the cover tape winding reel 13, the winding amount control means 43 performs
The distal end of the stopper lever 49 gradually approaches the winding lever 30, and gradually reduces the movable space between the winding lever 30 and the stopper lever 49. This stopper lever 49

As is clear from the above description, in the electronic component supply device 41 of the present embodiment, the take-up reel drive mechanism 1
The amount of rotation of the cover tape take-up reel 13 in the take-up direction by the spring force of the take-up spring 32 gradually decreases as the winding diameter of the cover tape 20 on the cover tape take-up reel 13 increases. The length of the tape that the take-up reel drive mechanism 15 takes up on the cover tape take-up reel 13 by the action of the spring force every time the shutter 9 moves in one return direction is always restricted to the component feed amount by the component delivery mechanism 11. .

Therefore, the cover tape take-up reel 13
Even if the winding diameter of the cover tape 20 is increased, no extra tension acts on the cover tape 20 due to the spring force used for winding after winding up by the feed amount by the component sending mechanism 11, It is possible to reliably prevent over-feeding of the taping electronic component 3 due to excess tension acting on the cover tape 20 after winding up by a feed amount corresponding to the feed amount by the sending-out mechanism 11, and to reduce the feeding accuracy of the taping electronic component 3. The improvement can improve the reliability of the component supply operation.

Is a single part in which the winding diameter detection arm 47 and the stopper lever 49 are integrated, and the range of action of the spring force in the take-up reel drive mechanism 15 is changed by the cover tape take-up reel 1.
Since the configuration is controlled in accordance with the winding diameter in 3 and the number of additional components is small and the configuration is simple, the object can be achieved at low cost.

In the present invention, the specific configurations of the take-up reel drive mechanism and the take-up amount control means are not limited to the configuration of the above-described embodiment, but may be appropriately changed without departing from the spirit of the present invention. It goes without saying that the design can be changed.

[0037]

According to the first aspect of the present invention, the amount by which the take-up reel drive mechanism rotates the cover tape take-up reel in the take-up direction by the spring force is determined by the diameter of the cover tape take-up reel. The tape length gradually decreases with the increase, and the length of the tape that the take-up reel drive mechanism takes up on the cover tape take-up reel by the action of the spring force at every one return operation of the shutter is always a part length by the part sending mechanism. It is regulated by the feed amount.

Therefore, even if the winding diameter of the cover tape on the cover tape winding reel is increased, after the winding amount corresponding to the feeding amount by the component feeding mechanism, extra tension is applied to the cover tape by the spring force used for winding. Therefore, excessive feeding of the taping electronic component due to excess tension acting on the cover tape after winding up by an amount corresponding to the feed amount by the component sending mechanism can be reliably prevented, and the taping electronic component can be reliably prevented. The reliability of the component supply operation can be improved by improving the component feeding accuracy.

According to the second aspect of the present invention, the range of the spring force acting on the take-up reel driving mechanism can be easily reduced by adding a single component integrating the winding diameter detection arm and the stopper lever. The control can be performed according to the winding diameter of the tape take-up reel, and the object can be achieved at low cost.
