りロールの経時変化する巻径 The present invention relates to a winding control method for winding webs such as cloth, paper, synthetic resin films, etc. while maintaining high quality, and a winding control device suitable for carrying out the method. When discussing the quality of a winding roll made by winding a web, emphasis is placed on the quality perceived from the appearance and the quality of the web to ensure that the quality of the web itself is not impaired by winding. It can be divided into substantive quality. The former concerns the winding wrinkles of the take-up roll and the alignment of the edges, and factors involved in this include the arrangement of the rollers and the driving method. On the other hand, the latter relates to shrinkage when the web is unrolled from the take-up roll and the degree of sagging due to changes over time during winding. Factors that are involved in this include the winding tension, the contact pressure of the Tatsuchi roller, the winding method, etc. can be given. Recently, the demands from users have become more focused on the quality of the web for take-up rolls, with the aim being to ensure that the width of the web is uniform and that the shrinkage rate does not differ between the surface layer and the inner layer. be uniform;
The winding hardness has become appropriate, and therefore the setting of tension and contact pressure when winding must be done rationally and scientifically, but in general, The reality is that we rely on methods such as selecting appropriate values based on data obtained from actual results and experience, and repeating experiments to determine the product that meets the requirements. However, there are various problems such as being unscientific and the quality differing depending on the skill of the driver, and furthermore, the amount of effort, time, and product loss required to obtain highly reliable data regarding winding is extremely low. From this point of view, there is a strong desire to realize a winding control system that can perform winding while taking into account the quality of the web itself on the winding roll, but a system suitable for this is still being proposed. This has not yet been achieved and is an issue that must be resolved by all concerned. In view of these circumstances, the present inventor has conducted various tests in order to provide a rational and scientific winding control system for maintaining high quality, and as a result, the present invention has been completed. It is something that has been achieved,
This makes it possible to perform winding while automatically and rationally applying appropriate winding tension and contact pressure, thereby ensuring stable and high quality over the entire length of the web to be wound. . However, in order to achieve such an object, the present invention aims to improve the winding density based on the fact that the winding density has a correlation with the winding hardness and is an important factor that influences the quality of the web itself. A directly controlled winding system has been specified and is characterized by the following configuration. In other words, the winding diameter of the winding roll changes over time during the winding process in which the web is wound around the winding core while applying tension and contact pressure.

Note that the winding density referred to in this specification has a correlation with the hardness of the winding layer portion of the winding roll, and refers to the volume ratio of the area around the winding core of the winding roll, and refers to the volume ratio of the area around the winding core of the winding roll. It is clear that the value is less than 1 in the case of flexible winding, and the value is greater than 1 in the case of hard winding, in which the tension and contact pressure are doubled. However, the winding density of the lever

[] In this equation, the denominator on the right side is the total cross-sectional area of the wound web, while the numerator is the cross-sectional area of the take-up roll excluding the core. The above factors t, l, and d are values unrelated to the tension value and contact force, and D is a value that can be easily determined when the winding roll is completed without considering these factors during winding. It is. Therefore, by knowing each factor related to standard products, it is necessary to determine the winding density.

Thus, at least one of the winding tension and the contact force is increased. On the contrary, the winding diameter

When [D] is smaller, at least one of the winding tension and the contact pressure is reduced. In this manner, the control for bringing the winding density into conformity with the set value is performed substantially continuously in synchronization with the basic clock pulse. Note that the proportional division ratio at which the control output of the microcomputer 16 is applied to the tension control system and the contact pressure control system can be determined by actually measuring each material and type of web W in advance. Although this can be easily determined, sequential operation is of course also possible, such as performing priority control and switching to the other when control becomes impossible. In addition, if the winding density is known from the original fabric, such as with a sliver or rewinder, the same winding density

The output terminal of the division circuit 23 shown in FIG. 2 is led to one input terminal of the multiplication circuit 33, and the output terminal of the circuit shown in FIG. In this way, so-called taper winding in which the winding density gradually decreases according to the thickness of the winding can be performed. As described above, according to the present invention, it is possible to control the winding so that the winding density during the winding operation matches the set value. Being able to directly control the determined winding density provides scientific control over the actual quality of the product.
This is an epoch-making method, and compared to conventional methods that relied on experience and intuition, it is an extremely useful means for winding that maintains quality that meets the user's needs. The advantage of being able to perform winding operation using numerical control in this way is that it can be operated easily and repeatedly based on data without being affected by the level of skill of the operator, leading to improved productivity. Moreover, it eliminates defective products and achieves a winding operation with stable quality and high yield rate, and its practical effects are remarkable.
