Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cord supply device that can switch and supply different types of cords to a calender roll.

Generally, in a tire manufacturing factory, a large number of parallel cords are coated with rubber from both sides using calender rolls, and members such as carcass are manufactured as follows. That is, first, after unwinding the cord from the creel stand on which the cord corresponding to the type of member is wound,
These multiple cords are passed through a com roll to separate and align the cords, and then fed to a calender roll. When changing the type of parts to be manufactured, the cord is switched. In this case, the cord is cut between the comb roll and the calendar roll, and then the excess cord is pulled back and one side is cut. ,
After the cord corresponding to the member to be manufactured later is unwound from another creel stand, it is connected to the rear end of the cord of the previously manufactured member.

−, however,
In such a system, each time you switch the code type, one code is inserted between each Comroll partition.
It is necessary to separate and align a large number of cords by passing them through each tree, which requires a great deal of time and effort to switch the cords, resulting in a problem of low work efficiency. Further, when switching, the operator must make adjustments to ensure that the cords do not overlap or intertwine at any part of the route, which also reduces work efficiency. Furthermore, a certain tension must be applied to each cord so that the cord does not sag during running and deviate from its path or become entangled with adjacent cords. To this end, the same number of tensioning means as the number of cords are provided. It is conceivable to tension each cord individually, but in this way the tensioning means would take up a large amount of space, and the creel stand would only be able to accommodate one type of cord, resulting in multiple cords. There is also the problem that when changing the type of cord, it is necessary to replace the cord in the creel stand.

The purpose of this invention is to omit the work of passing the cord through the comm roll when switching between cord types.

The purpose is to improve work efficiency. Another object of the present invention is to automatically separate and align a large number of cords when changing the type of cord, thereby improving work efficiency. Furthermore, another object of the present invention is to increase the space occupied by the cord by reducing the number of tensioning means, thereby storing many types of cords in one creel stand and switching between many types of cords. The goal is to be able to do this in a short amount of time.

The purpose of this is, first, to select a type from a creel stand where multiple types of cords are wound up, line up the many wound cords, and feed them to the calender roll that performs the rubber coating. This is a cord feeding device for calender rolls that separates and aligns a large number of cords from each other by passing the cords between a number of partitions provided corresponding to each type of cord, and a comb roll that separates and aligns each type of cord. A clamp body that clamps all at once, and a moving means that moves the comb roll and clamp body along the cord path between a supply position on the side closer to the calender roll and a large trick position on the side closer to the creel stand. Second, in addition to the first device described above, a device comprising By providing separate com rolls corresponding to each type of cord to separate and align the cords from the stock position, ``Thirdly, the above-mentioned f!/4
In addition to device 1, this problem can be solved by retractably providing one tensioning means that applies tension to these cords all at once on the cord path between the supply position of the output roll and the creel stand and the joint. be able to. −□
First, during the operation of the calender roll, after a large number of cords of the selected type are unwound from one of the daryl studs, another comb roll and a comb roll located at the respective supply positions and separated from each other are unwound. They are separated from each other, aligned, and fed to calender rolls. Since a predetermined tension is applied to the cord by the tension applying means, there is no possibility that the cord will deviate from the path and overlap or become entangled with each other.Next, when changing the type of cord, first After stopping the operation of the calender roll, the cord is clamped all at once by the clamp body, and then the cord is cut between the comb roll and the calender roll.Next, the tensioning means is retreated from the cord path to interfere with the cord. After preventing the occurrence, the comb roll and another comb roll are moved by moving means along the path of the cord to a stock position and stored. You unwind the selected cord from the creel stand and move the comb roll and another comb roll from the stock position toward the supply position by the moving means. At this time, the tip of the cord is clamped all at once by the clamp body. □Also, even after another comroll stops at another supply position, the comroll advances to that supply position. □Multiple cords are automatically separated and lined up by another dcomroll. Go in one line. 'Next, when the clamp body is removed, a predetermined tension is applied to the cord by applying tension lever 4rst. When the calender roll is stopped, since a cord is passed through both comb rolls, the rubber coating process can be started immediately on the calender roll.
