Abstract

A row of adjacent holding wheels (16) or spools is on a horizontal axis in a frame (14). These rotate freely on bearings, independently of each other. A winding unit (2) separate from the frame is brought into a working position with each of the wheels in sequence. The winding unit (2) and frame (14) are moved relatively to each other, to allow the winding unit to address each wheel in succession. The wheels are spoked. The frame is formed by a container for the wheels.

Description

The invention relates to a system for winding, storing and transporting aufblikbaren objects according to the preamble of claim 1.

The system according to the invention is generally intended and suitable for elongate, slim and flexible articles which can be wound up. A special field of application here are straps, namely safety belts of automobiles. Nevertheless, with the system according to the invention - as stated - other objects can be wound up, such as hoses, cables, etc.

So far, windable objects are wound on take-up wheels in the manner of film rolls. For this purpose, a corresponding winding device can serve.

Specifically, the straps of seat belts are wound by hand on cardboard cores. The disadvantage is the low capacity, since only 250 m belt can be wound up. In addition, it is necessary that each wrap individually packaged and handled individually for transport, which is logistically complicated. This is especially true when the belt manufacturer is not the belt processor and thus the belt rollers must be transported from the belt manufacturer to the belt processor over longer distances.

Based on this, the present invention seeks to provide a system for aufblikkelbare objects, by means of which these objects can be wound in a simple manner, stored and transported.

The technical solution is characterized by the features in the characterizing part of claim 1.

As a result, a system is created by means of which in a technically simple manner bevelable objects, such as straps, automatically wound, stored and transported. The basic idea of the device according to the invention is on the one hand in a receiving frame for the pick-up wheels and the other in a Aufwikkeleinrichtung. The frame for the pick-up wheels has the advantage that it can accommodate not only a single pick-up wheel, but a plurality of pick-up wheels. As a result, a compact unit is provided, which can be transported in this way by means of the frame from one place to another. Moreover, since the take-up wheels are freely rotatably mounted on the axis of the frame, these take-up wheels can remain permanently in the frame. For by turning the pick-up wheels, the corresponding objects can be wound without the respective pick-up wheel has to be removed from the frame and reinserted after winding or unwinding of the object. It is only necessary to attach the object to be wound directly or indirectly to the hub of the receiving wheel. Thus, the receiving wheel is easily rotatable on the axis, the hub preferably has a ball bearing. For winding the objects on the individual receiving wheels, it is only necessary to move the Aufwikkeleinrichtung and the frame with its receiving wheels relative to each other, so that the take-up device enters the effective range of the respective receiving wheel. This can be realized in a technically simple manner by a corresponding transport device. It is only necessary that after the complete winding of a take-up wheel, the take-up device is disengaged from this take-up wheel, the take-up means and the stand are moved relative to each other, and finally the take-up means is brought into operative connection with the next take-up wheel. Overall, the system of the invention has the advantage that is saved by the automatic winding staff. Furthermore, by arranging the take-up wheels in a common frame, the packaging and unpacking of the take-up wheels is eliminated. Finally, the system according to the invention with its pick-up wheels is characterized by a material-saving waste optimization, since rollers with a much larger diameter than heretofore can be used by means of the system according to the invention. While so far only 250 m in one piece can be rolled up on a roll when winding belts, it is possible by means of the system according to the invention, on the receiving wheels each roll up 1,300 m. Since the average loss per roll is approx. 2.5 m, this results in a material saving of approx. 10 m per roll with regard to the old rolls.

Preferably, according to the embodiment in claim 2, the receiving wheel as Speichenrad (from the basic principle as a film roll) is formed.

A further preferred embodiment proposes according to claim 3, that the frame is formed by a container for the receiving wheels. This has the advantage that on the one hand, the receiving wheels located in the container are protected during transport and that on the other hand, a simple transport is ensured by the container. Preferably, the containers are formed as pallets.

The development according to claim 4 has the advantage that the frame is passed clocked with the receiving wheels by means of a corresponding transport device to the take-up, so that a total of a continuous Aufwickeivorgang all pick-up wheels is possible. Because the racks can be passed in succession by means of a corresponding transport device in a continuous pass on the winding device.

For this purpose, the development proposes according to claim 5, to provide the central transport device for the racks before a task conveyor and behind a pickup conveyor. The empty racks can be placed by means of a forklift on the feed conveyor, while the full racks can be removed by means of the forklift from the pickup conveyor.

The development according to claim 6 proposes a preferred technical realization of the winding device. The basic principle of the winding device is that the actual winding unit is arranged in a gallows shape on a frame, so that the winding unit can dip from top to bottom in the receiving roller. The take-up unit comes into abutment with the object to be wound up so that the article, for example the belt, is transported further and the take-up wheel is rotated due to the frictional engagement built up thereby. For this purpose, a certain contact pressure is necessary.

The development according to claim 7 proposes a concrete technical realization of the winding device. Thus, in a first alternative, a driven roller may be provided. A second, preferred alternative proposes a driven endless belt, wherein this winding unit can be formed so elongated that it can easily dip into the pick-up wheel. For this purpose, the drive unit has a drive as well Guide wheel, which have a corresponding vertical distance from each other.

Finally, the development proposes according to claim 8, that the frame is associated with an inlet device for the wound object. This inlet device may in particular have two deflection rollers and a particular rubberized brake roller with mounted brake. By this inlet device ensures that the object to be wound with the necessary train the pickup wheel can be supplied to the Aufwikkeleinrichtung.

The system has a stationary base frame 1 made of steel profile. This base frame 1 serves firstly for receiving a winding device 2 and secondly - on the other side - for an inlet device 3.

The winding device 2 has a vertical column 4, in which a lifting device 5 is arranged and along which a vertically movable boom 6 is guided. This gallows 6 has at its front end to a run on two rollers endless belt 7. In this case, the lower roller serves as a deflection roller and the upper roller as a drive roller for a drive motor. 8

The inlet device 3 has guide rollers 9 and a brake roller 10 with mounted brake.

Associated with the base frame 1 is a transverse transport device 11. In front of this transport device 11 is a feed conveyor 12 and behind it a take-off conveyor 13.

Furthermore, a container-like frame 14 is provided, which stands on the transport device 11. This container-like frame 14 has an axis 15 in the interior, which extends in the transport direction of the transport device 11. On this axis 15 a plurality of receiving wheels 16 are freely rotatably mounted.

The operation of the system is as follows:

The wound object 17 in the form of a belt is guided over the deflection rollers 9 of the inlet device 3. This article 17 is intended to be wound on a take-up wheel 16 in the container-like frame 14.

For this purpose, a frame 14 with empty pick wheels 16 is placed on the feed conveyor 12 by means of a forklift. The frame 14 is pneumatically aligned on the feed conveyor 12.

The frame 14 then moves onto the transport device 11 and is there positioned via a surveying system so that the first receiving wheel 16 is centrally under the belt 17 of the take-up device 2.

An operator threads the object 17 to be wound into the above-described inlet device 3 with the deflection rollers 9. This object 17 is now connected (sewn, glued or the like.) With the attached to the receiving wheel 16 object which is secured by an eccentric closure.

Subsequently, the boom 6 moves with the rotating belt 7 by means of the lifting device 5 on the vertical column 4 of the take-up device 2 as far down until the tape 7 rests on the hub of the receiving wheel 16. By means of a preset pressure on the lifting device 5 and due to its own weight, a frictional force between the wound object 17 and the winding tape is achieved, so that the winding process starts automatically. About the brake roller 10, the tensile force and thus the winding hardness is determined. About the winding diameter, the winding speed is automatically adjusted and adjusted by parameters. As soon as the pickup wheel 16 is full, the machine shuts down automatically. The operator cuts off the article 17 and secures it by means of an eccentric closure.

Subsequently, the frame 14 by means of the transport device 11 clocked by the width of a receiving wheel 16 on, so that another winding process at the next pick-up wheel 16 can start. The process is repeated until the last pick-up wheel 16 has been equipped with the object 17. Are all pick-up wheels 16 full, the frame 14 moves to the pickup conveyor 13. From here, the full frame 14 can be removed with a forklift.

The full transport container can be transported for further processing, without the need for additional packaging. For this purpose, the frame 14 has a base frame formed as a pallet.

In the further processing station, the article 17 can be unrolled directly from the receiving wheel 16 for further processing.
