ORIGINAL INSPECTEO

It is well known that materials, in the form of a strip, are often grounded in very long and wide strips in order to ensure efficient production manufactured. On the other hand, there is the end user of these materials, including for example paper, plastic foils,

Aluminum foils and the like, the need to handilrher these materials in the form, for the consumption of certain roles su received.

Previously, the fttr consumption were certain small roles now Obtained from the large supply roll in such a way that as a core a cylindrical element was used for the rollers, which on a spindle was inserted and turned. The spindle was of sufficient length to be supported on both sides. The spindle was driven to wind up the strip-shaped material. at a newer system is provided with a vertical shaft, which can be moved gradually into certain angular positions and has several bearings for receiving τοη spindles. If now If a core is wound with the specified amount of the tape-like material, the tape is cut off and a new core is fed to be wound onto it. While the new role is wrapped, the already filled one is removed from the shaft *

This newer device thus saves time and labor by obviating the need to shut down the winder when cutting the ribbon and when changing cores. this is achieved in that the end of the tape coming from the supply roll is automatically wound onto the new core 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 be. The spindle must be removed from the finished rolls so that it is possible to produce longer rolls transversely to their axis of rotation cu durohfohnlden and lomit immal RoUtn lu trhaltfn,

In addition, it is necessary in the known device, one to keep a large number of spindles ready. The cylindrical element, i.e. the core, is generally made of cardboard, while the spindle is made of Elsen, has a polygonal cross-section and a length of over one meter, the length of the Spindle, of course, can be varied depending on the web board that can be processed on the WIK-.kelmachine. Aul everyone In this case, the insertion and removal of the splinta is extremely laborious.

In the German patent specification 1 114 377 there is also a machine for winding up material - in particular, paper web rolling described, which allows continuously small, for consumption produce certain rolls of tape-shaped material without the need to use spindles of the type described above which must be inserted into the core of the rolls before winding and pulled out of the core after winding. To this The purpose is the drum on which the material web is to be wound up from a plurality of formed parallel to the drum shaft, driven together and in the same direction of rotation, wherein the Drum is rotatable in steps about its longitudinal axis by the number of rollers corresponding parts of a revolution and each winding device contains two mutually adjacent rollers of the drum. With this device, each of the rolls to be wound passes through one after the other two take-up devices located on the circumference of the drum, whereby the material web is separated before the roll leaves the second take-up device in the sequence. In the first winder, there are two drum rollers as well as one liftable, idle loading roller in the space between the drum rollers and a rotatably driven take-up roller intended. The drum rollers are driven by several endless V-belts from a pulley of a motor. if

If one imagines the drum shaft stationary , then the drum rollers rotate at a speed corresponding to the number of revolutions of the motor. If, on the other hand, the drum shaft moves at a certain speed in one or the other direction of rotation with respect to the drum rollers, these receive a corresponding speed reduction or increase. This speed reduction or increase is in such a relationship to the speed of rotation of the whole drum that when the material web is rolled up between two drums in the form of a roll, the tension, ie the tensile stress in the material web is not changed by the fact that the rotates during winding drum shaft forward or backward. In addition, during the transfer from the first to the second take-up device, the roll is guided in the space between the two drum rollers in question and expediently also by guide belts running over this space.

In the aforementioned arrangement, the making of said speed is sverminderung. or increase is absolutely necessary, since otherwise a relative movement would arise in the case of a continuous feed of material from a large supply roll, which would lead to the formation of folds or to the material web being torn off. Which he-

generation of such a speed change with the necessary However, accuracy can only be achieved with great technical effort, which also increases the susceptibility of the system and a More rapid wear is required, since the speed changes in a short time interval, particularly in the case of systems that run very quickly must be made. The present invention therefore lies the object of the aforementioned device for the continuous production of small, for the consumption of certain rolls of thin, To further improve strip-shaped material, in particular the drive of the drum rollers continuously and without undertaking Changes in speed should take place.

This object was achieved in that the roll cores located in the receptacles are set in rotation by the rotating rollers by means of friction, so that for pressing the roll cores or rolls to be wound against the wall of the receptacle in the first and second winding position and at a constant distance pressure devices are provided from each other, the pressure devices for the first winding position contain a pressure roller which is driven in such a direction of rotation at the speed of the paper feed that it supports the rotating action of the walls of the receptacle, which cause the rotation of the roll core, and the pressure device for the second winding position presses against the roll in the receptacle and in

is driven at the speed of the paper advance in such a direction that it has the effect of the itself supporting the rotating walls of this recording, while the roll created by being wound onto the roll core during its transport from the first winding position to the second winding position is only held by two rollers that means for locking the amounts of material located on the rollers are provided through which a knife can be controlled in such a way that the band-shaped Material is severed as soon as there is a predeterminable amount of material on the roll in the second winding position is located and by which a switching of the drum is effected as soon as the band-shaped material has been cut the roll located in the first winding position is a different predeterminable amount of material, and that the separation point for the band-shaped material is chosen so that the resulting free end, possibly supported by other devices, automatically around the roll cores located in the first winding position.

It can therefore be seen that according to the present invention a significant Simplification compared to the previous arrangements is possible, through which a faster and smoother as well as cheaper Production of smaller, for the consumption of certain roles becomes possible.

Further features and advantages of the present invention are explained in more detail below with reference to a drawing.

For the consideration of the mode of operation of the device for carrying out the method according to the invention, it should now be assumed that the pawl is locked in one of the notches 15 'and thus prevents the main axis 7 from rotating. The receptacle Et should be in the first winding position 6. Then the receptacle I, which is closest to the receptacle Π in the clockwise direction, is in the second winding position 17 and the receptacle IV, which follows the receptacle Π counterclockwise as the next but one, is in the insertion position in which the Roll core is inserted (Fig. 1). The roll cores 19 who know be either hollow or solid, as has been auegeführt, each have a length dl · corresponds to the distance between the main pulleys 8 and 8 '. The roll cores 19 are mounted parallel to the main axis 7 in a container 20 and are not provided with a spindle or the like.

The roll core 19, which is located in the receptacle Π In the first winding position β (Fig. 1), is pressed by a first pressing device 26 against the outer surfaces of two of the rolls 10 and rotated in a direction that is necessary for the winding of the band-shaped material 1 is suitable 1st. The pressing device 26, the is shown in the drawing, there is an AnpreÜvalz ·, the However, the invention is not restricted to this form of anpreeel device.

is and cooperates with these in such a way that the roll core is rotated in a direction appropriate to the belt-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 pressing means.

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

In the selected Ausiühmngebei game, one of the Conveyor rollers 3 used. This roller is connected to a counter 30 which counts your revolutions and the hydraulic pressure unit 31 actuated, by which the knife 32 is actuated, which the band-shaped material cuts off. The printing unit 31 brings the knife 32 back to its starting position when the counter 30 has determined that the discharge

roller has made a predetermined number of revolutions, and that thus a correspondingly long tape is wound on the roll core. The severing of the strip-shaped material 1 with the aid of the knife 32 takes place between the first winding position 6 and the second Winding position 17, preferably immediately behind the first winding position 6.

After the band-shaped material is cut by the knife 32, turns the core of the roll In the recording I, which is in the second Winding position 17 is, under the action of the cones 10 and the Pressing device 27 continues without further winding up material. The piece of tape-shaped material that protrudes beyond the first winding position 1 after the item has been cut off, tends to by itself on the roll core in recording II, which you can see in the first winding position 6 is to wind up. Be there, however 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

At the same time, the roll _9, which was previously completely wound in the second winding position 17, falls onto the output conveyor belt and a new roll core is brought into the first angular position β. In this way the cycle explained is repeated.

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

Since the diameter of the roll changes in the first winding position 8 changes, it is necessary that the first Pressing device 26 is constructed so that a constant pressure is maintained exerts on the role, which should be done regardless of the changes in the diameter. In order to achieve this goal χα, the pressure roller 37 of the first pressure device 26 is mounted on a rotatably Fastened lever arm 38, which is actuated via a hydraulic pressure unit 39. The amount of air supplied to this unit is regulated in accordance with the changes in the diameter of the roll in the first winding position 6.
