Embodiment Construction

[0021] FIG. 1 schematically shows the structure of a loop stocker by means of which sections of a strip 1 can be buffered.

[0022] The loop stocker has a stocker inlet 2 at which the strip 1 can be fed to the loop stocker. Conveying is carried out at the inlet speed v1. According to FIG. 1 , the accumulator inlet 1 can be designed as an S-roll, for example.

[0023] Furthermore, the loop stocker has a stocker outlet 3 . The strip 1 can be discharged from the loop stocker via the stocker outlet 3 . Output is performed at exit velocity v2. The hopper outlet 3 can—like the hopper inlet 2—be configured, for example, as an S-roller 3 .

[0024] Between the hopper inlet 2 and the hopper outlet 3, a large number of upper 4 and lower 5, 6 rollers are arranged. The lower rollers 5 , 6 are generally arranged in a stationary manner. At least one of the lower rollers 5 , 6 —the roller designated here with reference numeral 6 —is driven.

[0025] Said upper roller 4 is usually arra...

Abstract

A band (1) is introduced into the pit entrance (2) of a looping pit. This band (1) is released from the looping pit at a pit exit (3). A segment of the band (1) can thereby be buffered. The entrance-sided drag (Z1) that exists in the band (1) at the pit entrance (2) is measured by means of an entrance-sided drag measuring device (9); the exit-sided drag (Z2) that exists in the band (1) at the pit exit (3) is measured by means of an exit-sided drag measuring device (10). The values of the entrance-sided drag (Z1) and the exit-sided drag (Z2) are passed to a control device (11). Depending on the entrance-sided drag (Z1) and the exit-sided drag (Z2), a control signal (m*, n*) for at least one driven roller (6) that is arranged between the pit entrance (2) and the pit exit (3) is identified by the control device (11) and is passed to the at least one driven roller (6). The band (1) buffered in the looping pit is acted upon by the at least one driven roller (6) according to the control signal (m*, n*).

Description

technical field [0001] The invention relates to a method for operating a loop stocker by means of which a section of a strip can be buffered. Furthermore, the invention relates to a data carrier having a control program stored on the data carrier for carrying out such an operating method. Finally, the invention relates to a loop stocker by means of which sections of strip material can be buffered. Background technique [0002] Loop stockers and operating methods for loop stockers are well known. In the prior art, the strip material is delivered to the looper stocker at the stocker inlet. At the stocker outlet, the strip is output from the loop stocker. The tension present in the strip is detected by means of a tension measuring device. Alternatively, the tension measuring device can be arranged at the inlet of the stocker or at the outlet of the stocker. Input the detected pulling force into the control device. By means of the detected pulling force, the control device...
