DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product tape in a winding machine in which a steel tape is formed by a press machine, and a chained product tape which has been pressed is superposed on a paper tape and wound on a take-up reel. The present invention relates to a winding method and a product guide for guiding a product tape and a paper tape.

[0002]

2. Description of the Related Art A conventional product guide of a winding machine is disclosed in, for example, Japanese Patent Application Laid-Open No. 61-123416, in which a product guide is supported on a machine frame in a hanging state to wind a product tape. At the start, the product guide is rotated by about 90 ° to make it horizontal, and the starting end of the product tape sent by the feeding roll is guided on the paper tape wound on the core and wound up by overlapping with the paper tape. After the start of the product tape has been wound, the product guide is returned to the standby position in the hanging state, and the product tape is wound on the take-up reel.

Therefore, the conventional product guide has been used only to prevent the product tape from sagging at the start of winding and to attach the starting end of the product tape to the winding core of the take-up reel.

Since the product guide is retracted to the standby position during the winding of the product tape after the start of winding, the conventional winding method uses a product tape from the horizontal direction and a paper tape from the vertical direction to the core. The supplied product tape and paper tape were separately wound and polymerized on the core.

[0005]

When the product tape and the paper tape are wound on the take-up reel at high speed, the product tape and the paper tape are wound while pulsating up and down, left and right. Occurs, and the load collapses during transport of the full-diameter full reel.

[0006] In addition, as for the take-up reel, a cardboard reel whose side plate is made of cardboard is often used. A problem arises in that the product comes into contact with the inner end surface of the side plate and becomes defective, or the paper tape is damaged.

According to the present invention, in order to solve such a problem, a product tape and a paper tape are supplied from the same direction through one product guide from the start of winding to the completion of winding.
An object of the present invention is to provide a method of winding a product tape in which two tapes are simultaneously polymerized and wound, and a product guide for implementing the method.

[0008]

A method of winding a product tape according to the present invention is a method of winding a product tape formed by a press machine onto a take-up reel by superimposing the product tape on a paper tape,
After attaching the starting end of the paper tape that has passed through the product guide to the winding core of the take-up reel, the starting end of the product tape that is guided and supplied by the product guide overlaps with the paper tape and winds up, increasing the winding diameter. When the running paper tape approaches the side wall of the product guide, it is detected by a sensor provided on the side wall, and the product guide swings outward during the detection by the sensor, and the detection of this sensor and the swing of the product guide are performed. The product tape and the paper tape are repeatedly polymerized and wound at the same time until the winding is completed.The product guide of the present invention has a reflective photoelectric sensor embedded in a side wall of the product guide, and the product tape is wound. The diameter is detected at the position of the paper tape.

[0009]

Since the product tape and the paper tape are guided in a single product guide to face each other and are supplied in the same direction, the product tape and the paper tape are wound at the winding contact having the winding diameter. At the same time, they are polymerized and wound on a take-up reel. For this reason, even if the product tape pulsates at a high speed, the left and right positions of the two tapes are eliminated, and the two tapes are wound uniformly.

[0010] Products formed by a press machine change shape and gloss when the product changes, but the paper tape is the same paper quality tape even when the product changes (use paper tapes with different widths depending on the product size). If the paper tape is detected by the reflective photoelectric sensor, it is not necessary to adjust the sensitivity of the sensor, and it is always possible to accurately detect the predetermined interval with the running paper tape. Swing can be controlled correctly.

Since the end of the product guide faces the winding contact of the take-up reel and is wound from the start of winding to the completion of winding, even if the side plate of the take-up reel is deformed, the product tape is not removed. And paper tape do not contact the side plate.

Therefore, it is possible to completely prevent an accident in which the product tape or paper tape comes into contact with the side plate during the winding, to speed up the winding machine, and to uniformly displace the product tape and the paper tape without left and right displacement. Since it is wound, there is no danger that the cargo will collapse during transportation.

When the winding diameter of the wound product tape W becomes large and the reflection type photoelectric sensor 47 detects the traveling paper tape V, the rocking motor 15 operates during the detection and the product guide 40 is raised. Rocks. The product tape W is wound up by repeating the detection of the sensor 47 and the ON / OFF of the swing motor 15. At this time, the guide table 18
Since the product guide 40 protrudes from the drive shaft 13 and swings with the long and short parallel links 17 and 21 using the two drive shafts 13 as fulcrums, the tip of the product guide 40 follows the locus of S shown by the dashed line in FIG. The product guide 40 swings in a state of being oriented in a tangential direction connecting the winding diameter and the feeding roll 32 in accordance with the winding diameter, so that the running product tape W contacts the inner wall surface of the product guide 40. do not do.

When the winding reel 3 is fully wound, it is detected by the reflection type photoelectric sensor 34, and the winding motor 7 is stopped. After the end of the product tape W is cut by the cutting cutter 52, the winding motor 7 is operated again to wind the end of the product tape W connected to the cutting cutter 53. At this time, the end of the paper tape V is pasted and adhered by the pasting device 56. Since the sample cut by the cutting cutter 52 is dropped on the guide table 18, it is convenient to attach the sample to the full reel with an adhesive tape since the product of the full reel can be visually identified.
