DE1093658B - Device for automatic monitoring and lateral guidance of the webs made of paper or other materials in processing machines for such webs - Google Patents

Description

The main patent application relates to a device for automatic monitoring and lateral guidance of the Web of paper or other materials in processing machines for such webs, such. B. Tubing machines, printing machines, textile machines or the like, with at least one touch point for each path and devices controlled from this scanning point by means of optical or electrical scanning means for correcting lateral adjustment of the web rolls to be unwound. For processing machines with several lanes, there is a touch point for each lane with the associated amplification device, timing element and control means for the lateral displacement of the web rolls, insofar as this occurs during operation is necessary, required. This results in a cumbersome and expensive construction of the machine with relatively large space requirements for the control devices.

The purpose of the invention is to simplify these systems while saving space and costs. Achieved this is the fact that in accordance with a monitoring and lateral guide device according to the main patent According to the invention, in the presence of several tracks, the scanning points assigned to the individual tracks one after the other via a common amplifier device in corresponding series and Time sequence with the associated lateral adjustment of the web rollers of the scanned by them Railways are brought into cooperative connection.

A switching device can be used between the sampling points and the common amplifier device which other than the sequential power-up connections between these devices simultaneously the connections between the common amplifier device and the respective associated web adjusting device produces. Further details of the invention are in the description explained in more detail in connection with the drawings.

Fig. 3 shows only to explain the switching options, not as an object of the invention, a circuit diagram of the electrical interrelationship of the optical and electrical control devices for the side correction of the web.

In the drawing, 1 is a camshaft with, for example, six switching cams 2, each of which each associated with a path of the web processing machine. The switching cams 2 are in the same Angular distances distributed over the circumference of the camshaft 1 and offset from one another in the axial direction arranged. They each act via a roller 3 and a support lever 4 for this on an associated one Switch 5 on. With each revolution of the camshaft 1, the switches 5 are in succession operated once. The camshaft 1 is connected to the planetary spur gears 6, 7, 8, 9 via a planetary gear train as well as a pair of spur gears 10, 11 from the feed roller rotating at web speed or -roll 12 driven, each facing a counter-pressure roller or roller 13 for each paper web is arranged. The gear ratio produced by the planetary gear 6 to 11 for the Camshaft 1 is chosen so that with each revolution of the camshaft 1, the path speed rotating feed rollers 12, 13 the paper web to one of the web length between to be unwound Paper web roll and associated touch point 14 move the corresponding amount. Be there according to the speed of the feed rollers

12, 13 successively via the respective associated switch 5 the connections between the six Paper webs 21 to 26 assigned scanning points 14 and the common amplifier device on the one hand as well as between this and the individual paper roll side control devices manufactured.

For each of the six paper webs 21 to 26, for example, there is a scanning point 14, a common one Amplifier device and between these each a switching cam 2 with associated switch 5 and the associated timing element provided. The drawing shows the paper sack making machine Separating knife arrangement 15, 16 for the tube sections, the longitudinal strip gluing device 17 with Counter roller 18 and the web guide rollers 19, 20 for the individual paper webs 21 to 26 are shown.

In adaptation to the respective cases of practice, depending on the number of paths to be processed Provide fewer or more than six switching devices 2 to 5 or switch and drive accordingly.

The operation of the tube drawing machine shown as an embodiment with six Paper webs is as follows:

The associated touch point 14 with the photocell arrangement 43 as an optical scanning device for the associated paper web, ζ. B. 21, is via the associated double switch 5 with the common amplifier device 44 and the timing relay 45 connected (Fig. 3). At the same time, the Switch 5 the connection between the common amplifier device 44, the timing relay 45 and the associated paper roll control device 46, 47 for left or right rotation of the motor 27 to the lateral Correction shift of the paper roll established. This process is repeated in succession for the individual paper webs 21 to 26 at all six switching points and the associated ones Switching devices 2 to 5, for example, at angular intervals of 60 ° each, so that during one revolution the camshaft 1 for all six paper webs 21 to 26 each one automatic monitoring and The lateral guidance check has been carried out. The same process is then repeated again for the first paper web 21 and then for the remaining paper webs 22 to 26. The speed of the camshaft 1, as with the main patent application, depends on the length of the track between the respective Paper web rolls and the associated touch point as well as the web speed.
