As is known, tape-shaped materials are used to ensure efficient production to ensure, often produced in very long and wide strips. On the other hand, the end user of these materials to which, for example, paper, plastic films,

Aluminum foils and the like include the need for these materials in the form of a handy, for the consumption of certain roles.

Previously, the small roles intended for consumption were now obtained in such a way from the large supply rolls that a cylindrical element was used as the core for these rolls, which on a spindle was inserted and turned. The spindle had a calibrating lye, ΐΠΏ mounted on both sides ZU \ νθΓ <αβΠ. To the nUiSpU ~

The spindle was driven len of the band-shaped material. at A newer system is provided with a vertical shaft that can be moved gradually into certain angular positions and has several bearings for receiving spindles. If a core is now wound with the specified amount of the strip-shaped material is, the tape is cut off and fed to a new core to be wound on this. While the new role is wound, the already filled one is removed from the shaft.

-S-

This newer facility thus saves time and labor by eliminating the need bypasses turning off the winder when the tape is cut must be and when the cores are changed. This is achieved in that the end of the coming from the supply roll The tape is wound onto the new core by itself after it has been cut. On the other hand, this new facility is also, in spite of the listed advantages, not without disadvantages. The spindles must be inserted into the cores before they are inserted into the winding machine can throw »The spindle must be removed from the finished rolls, so that it is possible to cut through longer rolls transversely to their axis of rotation and thus narrow ones ·. To get roles.

In addition, it is necessary for the connected device to have a to have a large number of spindles "ready. The cylindrical elsment, i.e. the core, is generally made of cardboard while the spindle is made of iron, has a polygonal cross section and a length of over one meter, the length of the Spindle, of course, depending on the web width on the winding machine can be processed, can be varied. In any Case. inserting and removing the spindles is extremely troublesome.

The innovation is now based on the task of a device to propose that makes it possible to continuously produce small, intended for consumption rolls of tape-shaped material. The production should be possible in such a way that the use of a spindle can be dispensed with and as a core for the rollers only the usual cylindrical Clied is used, so that the spindle is neither pushed in nor pulled out before winding the spindle is required after winding.

This object is achieved according to the innovation in that a rotatable drum with at least three evenly distributed around the circumference Recordings for roll cores is provided that facilities are provided for stopping the drum in such positions, in which each of the recordings is successively in an insertion position and at the same time a further receptacle is in a first winding position and a third receptacle is in a second winding position, that devices are provided for inserting a roll core into the receptacle located in the respective insertion position, that the walls of the receptacles are formed by rollers rotating in the same direction, the axes of which run parallel to the drum axis and by means of friction, the roll cores located in the receptacles rotate, that means for feeding the band-shaped Material are provided in the first winding position that separate pressing devices

B 3827

for pressing the roll cores or rolls to be wound onto the walls of the receptacles in the first and second winding positions are provided that devices for determining the material located on the rollers are closely provided by the a knife can be controlled in such a way that it cuts through the strip-shaped material as soon as it is in the second winding position There is a predeterminable amount of material located on the roll and by means of which the drum can be switched as soon as there is the severing of the strip-shaped material on the roll located in the first winding position another predeterminable amount of material is located and that the separation point for the strip-shaped material is arranged such that the resulting free end is automatically around the roll core located in the first winding position.

According to the innovation * all, the advantage is achieved compared with the known winding device vo ^1, that the insertion of the spindle, which has a large weight, and removal of the spindle is unnecessary. In addition, according to the innovation, the roll core can be both hollow and solid, since no spindle has to be pushed through the core.

The innovation is explained in more detail below with reference to the drawing.

It is now assumed that the pawl is locked in one of the notches 15 * and thus prevents the main axis 7 from rotating. The receptacle Π should be in the first winding position 6. Then the receptacle I, which is closest to the receptacle Π clockwise, is in the second winding position 17 and the receptacle IV, which follows the receptacle H counterclockwise as the next but one, is in the loading position in which the Roll core is inserted (Fig. 1). The roller cores 19, which can be either hollow or solid, as already stated, each have a length which corresponds to the distance between the main disks 8 and 8 '. The roll cores 19 are stored parallel to the main axis 7 in a container 20 and are not provided with a spindle or the like. The roller cores 19 stored in this way are reinforced via a conveyor line, dip rhimh Acm ΠΗοτ> ίοίΐ oinoa "conveyor belt 21 is formed is provided, which normally blocks the front end of the conveyor line 22, so that the roll cores are prevented from falling off the conveyor line 22.

Stello pointed out that the continuous working of the conveyor belt 21, which is used to deliver the roller drivers 19 over the conveyor line 22 into the insertion device 18, causes all the roller core to rotate around its own particular MhßQ & d of the conveyor line as a result of the rotation the RoUerifcerne in the conveying line is transferred to the Rollealcerne 19 in the container 20 and thereby the ecwssung dor RollelseraO; dio arrive one after the other from the container onto the conveyor line 22, conveys

When the hydraulic drying unit 23 is actuated, the lifting arm 24 first moves downwards, before it takes over the front end of the conveyor line 22 and one of the hoop cores 19. After the lifting arm has a lifting arm 30 on its upper door, lnQVtQgjL © r upwards and places it in the receptacle W, which is now in the insertion position and stops again in its upper position. When the lifting arm 24 stops in its inoperative position, the end 22 of the conveyor line is closed. The RoUenkeras 19, which are inserted one after the other in the receptacles © I to VI, which reach the insertion points 1 $ one after the other, are also brought one after the other into the first angle, τ & ηη the main axis 7

is and cooperates with these in the way that the core of the role is twisted into a rieliring that eats suitable to the band-shaped Winding material on it. The belt 29 is under increasing tension as the amount of material wound on the roll core grows and always works better as a contact pressure.

It is understood that the pressing device 27 according to the present Invention is not limited to the form specifically shown. The amount of material wound onto the roll core can be determined by determining the distance covered by the circumference of the conveyor rollers can be determined. But you can also use another roller that is in frictional contact with the material, or can be determined by the number of revolutions that the rollers make »

In the chosen embodiment, one of the scanning rollers is used Conveyor rollers 3 used. This roller is connected to a cooler 30, who counts their revolutions and actuates the hydraulic pressure unit by which the knife 32 is actuated, which the strip-shaped material cuts »The printing unit 31 brings the knife 32 back to its starting position when the counter 30 has determined that the scanning

roller has made a specified number of revolutions, and that thus a correspondingly long tape is wound onto the pulp core. The cutting of the strip-shaped material 1 with the handle of the knife 32 takes place between the first winding position 6 and the second winding position 17, preferably immediately behind the first winding division 6th

After the band-shaped material has been cut by the knife 32, the hollow core rotates in the recording I, which is in the second Winding position 17 is, under the action of the rollers 10 and the pressing device 27, constantly on, without further winding up material. The piece of tape-shaped material that protrudes beyond the first winding position 1 after the tape has been cut off tends to by itself on the roll core in the recording Π, which is located in the first angular position; 6 is located to wind up. However, there is the There is a risk that this effect will not occur if the strip-shaped material 1 has a certain rigidity. This difficulty can be overcome

The nozzle set 34 is blown in the direction of the first winding position 6 will. Before the new core is wound, the counter 30 is returned to its zero position and now counts the revolutions, caused by the material that is wound onto the new core.

As soon as a predetermined amount of material is in the first winding position is spooled on the roll core, the printing unit 23 is operated via a second counter which counts the revolutions and is coupled to the counter 30, so that the lifting arm 24 is in the currently inserted position insert a new roll core. Simultaneously

the pawl 16 is released to later move into the next notch 15 ' to click into place. At the same time, the main axis 7 is connected to a power source via a coupling (not shown) and is clockwise turned. The main axis 7 rotates very slowly and is after

1 / 6th of a turn when the pawl 16 is in the next notch 15 ' clicks into place, stopped again. In addition, the

Power source separated from the main axis 7.

The rotation of the main disks 8 and 8 'caused by the rotation of the main axis 7 has the consequence that the roller core is in the open position

At the same time, the roll that has previously been completely wound in the second winding position 17 falls onto the output conveyor belt and a new roll core is brought into the first winding position 6. In this way the cycle explained is repeated.

The second counter 35, which is connected to the first counter 30, is brought into its zero position at the same time, like this one.

f Since changes during the winding of material, the diameter of the roller in the first WickelstJllung 6, it is necessary that the first pressing device 26 is constructed so as to exert a constant pressure on the roll, to which take place independently of EQS changes in the diameter . In order to achieve this goal, the pressure roller 37 of the first pressure device 26 is attached to a rotatably mounted lever arm 38 which is actuated via a hydraulic pressure unit 39. The amount of air supplied to this unit is regulated according to the changes in the diameter of the tube in the first winding position 6.
