Abstract

PROBLEM TO BE SOLVED: To remarkably simplify the laying of a cable by providing one natural regulating device on each winding arm, and fixing the regulating device to the winding arm itself. SOLUTION: One regulating device 10 is fixed to each winding motor 6, and the regulating device 10 is moved together when the winding arm 6 is moved. Since the regulating device 10 is fixed to the lower part of the winding arm 6, for example, onto a holding plate 11, the regulating device 10 is extended with a space as small as possible substantially in parallel to the wall of a horizontal beam 1. The regulating device 10 has a regulating motor 7 and a switching element necessary or amplifier for supplying an energy to the winding motor 9 and controlling it. Thus, the regulating device 10 is connected to the regulating motor 7 and the winding motor 9 through corresponding feed cable and signal cable. A contact piece 12 extended over the whole regulating process of the regulating arms 6 juxtaposed in parallel to each other is fixed to the horizontal beam 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The invention relates to a winding for winding a strip of longitudinally cut material made of plastic, paper or the like, according to the preamble of claim 1. About the machine.

[0002]

2. Description of the Prior Art Conventionally known winding machines are used for winding a strip of plastic, paper or the like, which has been divided into narrow strips by longitudinal cutting. The winding machine has a series of winding stations, which are arranged in two winding lines, both of which are supplied with strip material selectively. Each winding station consists of two winding arms, each having one tightening head, said tightening head being able to enter into the winding roll sleeve to hold the winding roll laterally; It can be rotated by a winding motor.

The winding arm of each winding line is mounted on a common cross beam so that it can be positioned in the horizontal direction by an adjusting motor for format adjustment, which adjusting motor is likewise fixed to the winding arm. Have been.
Thus, each winding arm has one winding motor and one adjusting motor, the motors must be supplied with electrical energy as electric motors and must be individually controlled.

[0004] Known winding machines have in each case one adjusting device (also called an amplifier or amplifier) mounted in a fixed position for controlling the individual motors, the adjusting device comprising an electric motor. Network and a central control unit. From the adjusting device, an energy supply line and a signal line are guided to each of the two motors provided on each winding arm. If new AC servomotors are used, at least two cables (control cable and output cable) with up to 13 lines must be guided to each motor.

In the case of a winding machine having a large working width of up to 10 m, a maximum of 60 winding arms with two motors each can be used to obtain narrow winding rolls having a width of, for example, 300 to 350 mm. It is necessary to lay cables accordingly. In this case, the laying of the cable must not interfere with the lateral positioning of the winding arm. Overall, very thick cable bundles are required, and such cable bundles must be guided with correspondingly high costs, for example in chains.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to improve a winding machine of the type mentioned at the outset and to provide a winding machine in which the cable laying is considerably simplified.

[0007]

This object is achieved according to the invention by a winding machine according to the invention as defined in the characterizing part of claim 1.

[0008]

According to the invention, each winding arm has a unique adjusting device, which is fixed to the winding arm itself. At least the supply of energy from the network, preferably the control of the winding motor of the winding line, also takes place to the respective winding arm via the commonly used sliding contact line. Said sliding contact lines are arranged along or in the cross beam and are connected to the adjusting device via sliding contacts.

[0009] A particularly advantageous configuration of the invention is described below.

[0010]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of an embodiment of the present invention.

The winding machine has, in a known manner, two winding lines, each with a consistent crosspiece 1, 2 on which a series of winding stations is mounted. Have been. Individual strips 3 produced by longitudinal cutting from strips having a width of up to 10 m are selectively fed to winding stations of both winding lines and wound on winding rolls 4,5. . The winding stations of both winding lines are configured identically, and the structure is described in more detail below based on the winding line on the left in FIG.

Each winding station consists of two winding arms 6 mounted on the cross beam 1 so as to be laterally adjustable, ie movable in the direction of the longitudinal axis of the cross beam 1. For this lateral adjustment, one adjusting motor 7 is fixed to each winding arm 6. At the end of each winding arm 6 is supported a clamping head 8 which can be inserted into the sleeve of the winding roll 4, which is used to rotate the winding roll 4 during winding. It is driven by a winding motor 9.

An electric motor such as an AC servomotor is preferably used as the adjusting motor 7 and the winding motor 9. These motors are energized and controlled by the elements described below.

An adjusting device 10 is fixed to each winding motor 6, so that the adjusting devices 10 move together as the winding arms 6 respectively move. Advantageously, the adjusting device 10 is provided in the lower part of the winding arm 6,
For example, being fixed to the holding plate 11, the adjusting device 10 extends substantially parallel to the wall of the cross beam 1 and with the smallest possible spacing. The adjusting device 10
It has the switching elements or amplifiers and the like necessary to supply energy to the two motors 7, 9 and to control them. The adjusting device 10 is therefore connected to both motors 7, 9 via corresponding supply and signal cables.

Fixed to the cross beam 1 are sliding contacts 12 which extend in parallel and side by side over the entire adjusting stroke of the winding arm 6 and which are connected to an electrical network. And serves as a common supply line for all motors 7, 9 in the winding line. Thus, depending on the type of motor used, only three or four sliding contact pieces 12 are required to supply energy to each winding arm 6. Sliding contact piece 1
2 is in contact with the sliding contact 13 of the adjusting device 10 in any position of the winding arm 6 relative to the cross beam 1. With such an arrangement, only the cables required for the motors 7, 9 need to be laid between the adjusting device 10 and each motor 7, 9, and all cables can be laid immovably. . This is because the cable length does not change even if the position of the winding arm 6 is adjusted.

Advantageously, the cable laying for the signal lines takes place in a similar manner, so that the signals for controlling the adjusting device 10 also have a common bus line fixed to the crossbeam 1. Conveyed through. For this purpose, a commonly used bus line is laid along or within the cross beam 1, which is also formed as a sliding contact piece fixed to the cross beam 1. Such a sliding contact piece is also in contact with the sliding contact of the adjusting device 10. The adjusting device 10 also has corresponding electrical elements for filtering the corresponding signals and for controlling the corresponding supply lines to the two motors 7,9.

Alternatively, control signals can also be transmitted wirelessly to the individual adjustment devices 10. In this embodiment, each adjusting device 10 has the required receiving electronics, respectively, in order to receive and further process wirelessly transmitted signals, such as, for example, high frequency signals or infrared signals (IR-Signals). Control electronics.
