Problems solved by technology

[0007]However, in the lateral position control of the web using guide rollers, when the above-mentioned slip of the web occurs, even if the relative angle of the guide rollers is changed, it still causes Sliding of the thin strip, unable to control the thin strip in the specified lateral position
Moreover, in the existing thin strip control method, in the case of a change in the conveying speed due to "disturbance", since the slip of the thin strip cannot be controlled, the lateral position control of the thin strip using the guide roller Sometimes, the tension of the thin strip is high and longitudinal bending occurs between the guide roller and the thin strip, causing wrinkles on the thin strip, or sometimes the tension of the thin strip is small and the thin strip will slip even if the relative angle of the guide roller is changed. without the ability to control the lateral position of the strip

Embodiment Construction

[0027] First, the overall configuration of the conveying line 1 for the web 2 will be described below.

[0028] like figure 1 As shown, the conveying line 1 of this embodiment is provided with a reference roller 10 on the upstream side of the conveying direction of the thin strip 1, and a feed roller 11 is arranged on the downstream side of the conveying direction of the thin strip 2, and from the reference roller 10 to the downstream side (Feed Roller 11) Guide rollers 12·13·14·15, dancer rollers 16, etc. are arranged in this order, and the web 2 is conveyed by being wound by these guide rollers 12 etc. at a predetermined contact angle.

[0029] Nip rollers 17·18 are provided on the reference roller 10 and the feed roller 11, respectively. The pinch rollers 17·18 are configured to be in pressure contact with the reference roller 10 and the feed roller 11 respectively by means of an unshown cylinder or the like, so as to prevent the thin strip 2 from being placed on the refer...

Abstract

A method of controlling the conveyance of a web comprises a web measuring step of measuring the conveyance speed (V) and the tension force (T) of the web (2) during its conveyance, a slip amount calculation step of calculating the slip amount (W) of the web (2) relative to a guide roll (14) from the values of the conveying speed (V) and the tension force (T) of the web (2) measured in the web measuring step, and a web control step of controlling the tension force of the web (2) during its conveyance so that the slip amount (W) of the web (2) relative to the guide roll (14) calculated in the slip amount calculation step is equal to a preset target slip amount (W1). Consequently, the slip of the web is accurately controlled, whereby the lateral displacement of the web can be reduced.

Description

technical field [0001] The present invention relates to a web conveyance control method, a sliding amount measuring unit, and a conveyance control device. Specifically, it relates to web conveyance control for continuously conveying the web while controlling the slip of the web relative to rollers provided on a conveying line. The technology of the method, the slip measurement unit and the conveyance control device. Background technique [0002] Conventionally, a conveying line for continuously conveying elongated objects (thin strips) such as electrode members used in secondary batteries and a conveying control method thereof are known. In such a conveying line, the conveying speed and tension of the web are feedback-controlled (web conveying speed control and tension control) by controlling the driving of various rollers provided on the conveying line, so as to stably Convey thin strips. [0003] However, in such a conveying line, the transverse position of the web (the ...
