BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a belt-shaped carrier portion serving as a holding portion at the time of feeding after a steel tape or the like is processed by a press machine, and a number of terminals projecting from the carrier portion to become products. The present invention relates to a feeder for a winder, which sends a product tape to a cutter device side and arranges and stops a carrier portion between the terminals at a cutting position of the cutter device at the time of sampling.

[0002]

2. Description of the Related Art Conventionally, this kind of feeder has been disclosed in
As described in JP-A-58914 and JP-A-61-123416, a feeding device having a feeding roller driven to rotate is provided.

A pin which can be inserted into a hole such as a pilot hole regularly formed in a carrier portion is provided on an outer peripheral surface of the feeding roller so that a product tape can be fed without slipping when the feeding roller rotates. It was set up.

[0004] The feeding roller is driven to rotate by a predetermined rotation driving motor, and a sensor such as a photoelectric switch capable of detecting the rotation speed of the feeding roller is arranged around the feeding roller. At the position, a control device for inputting a signal from a sensor to calculate the feed distance of the product tape, and for controlling the operation / stop of the rotation driving motor of the feeding roller was arranged.

When the feed device stops feeding of the product tape and performs sampling while the feed device is feeding the product tape to the cutter device used at the time of sampling, the control device places a product terminal at a cutting position of the cutter device. So that only the carrier part between the terminals is arranged,
It has been operated to stop the rotation drive motor and stop the feeding of the product tape.

[0006]

However, in the conventional feeding device, the product tape can be inserted into a hole such as a pilot hole regularly formed in a carrier portion on an outer peripheral surface of a feeding roller of the feeding device. Pins protrude.

Therefore, when the product tape is changed, the pitch of the pilot holes and the like is changed, so that the pitch of the pins protruding from the outer peripheral surface of the feeding roller must also be changed. It becomes necessary to replace the feed roller with the pitched pins projecting.

[0008] However, in the manufacture of a feed roller having pins of a corresponding pitch protruding, one round of the outer peripheral surface is 1 inch.
The diameter of the feeding roller is set so as to be an integral multiple of the pitch, and a predetermined number of pins must be arranged at equal intervals on the outer peripheral surface of the feeding roller of that diameter. It took a lot of man-hours and cost.

For this reason, the conventional feeding roller and, consequently,
In the feeding device, when the product tape was changed, coping was not smoothly performed.

The present invention has been made to solve the above-mentioned problem, and even if the product tape is changed, it is not necessary to replace the feeding roller, so that the feeding roller can be manufactured very easily. It is intended to provide a device.

Feeding device, a sensor disposed between the feeding device and the cutter device for detecting passage of the product tape terminal, and a control device for inputting a signal from the sensor to stop the feeding device. Wherein the feeding device includes a feeding roller and a holding roller each having a smooth holding surface for holding the carrier portion of the product tape, and the feeding roller has a front end. The cutter device is rotated by a rotation drive motor controlled by the control device.
Cuts two positions along the product tape feed direction.
And a product tape feed length
The distance between the pair of cutters can be adjusted to suit
It is characterized by comprising.

[0012]

In the feeder according to the present invention, first, the control device detects the passage of the terminal from the sensor and outputs a stop signal to the rotary drive motor, and then feeds the product tape. Is completely stopped, and the timing at which the carrier portion between the terminals can be arranged at the cutting position of the cutter device is input.

When the feeding roller is driven to rotate by the operation of the rotation driving motor under the control of the control device, the product tape held between the feeding roller and the holding roller is sent to the cutter device used for sampling. Can be

Thereafter, at the time of sampling, the control device detects the passage of the terminal from the sensor, stops the rotation driving motor at a predetermined timing, and arranges the carrier portion between the terminals at the cutting position of the cutter device. Can be done.

Since the sensor disposed at a position distant from the feed roller detects the passage of the terminal, the feed roller simply holds the carrier portion of the product tape in cooperation with the holding roller. Since the product tape can be sent by slipping, unlike the conventional method, it can be configured in a columnar or cylindrical shape with a smooth outer peripheral surface together with the nipping roller. Even
No need to replace.

Therefore, in the feeder of the winding machine according to the present invention, even if the product tape is changed, it is not necessary to replace the feeding roller, and the manufacturing of the feeding roller can be performed very easily.

7 and is taken up by a take-up reel R on the holding plate 11 at the take-up position A.

When the control device 45, which has received the signal from the photoelectric switch 40, calculates the length of the product tape W sent and determines that the product tape W is fully wound on the take-up reel R. Then, the rotation drive of the winding motor 13 is stopped so as to perform sampling. The product tape W
When is wound on the take-up reel R, as described above, the one-way clutch 33 allows the feeding roller 35 to rotate freely even when the rotation driving motor 32 is not operating, and the product tape W passes through the portion of the feeding roller 35.

Thereafter, the control device 45 operates the rotation drive motor 32 of the feeding device 31 to feed the product tape W forward to the front side by about 5 to 10 mm for one to several pitches between the terminals T,
When the passage of the terminal T of the product tape W from the photoelectric switch 40 is detected, the rotation drive motor 32 is stopped at a predetermined timing.

Then, the carrier portions K between the terminals T are arranged on the cutters 55 and 56 which are the cutting positions of the cutter device 50.
