Description

Device for feeding paper bands used by a machine that manufactures a packaging material of type of padding and a machine equipped with said device.

The invention is related to a configuration for continuous paper supply and with one machine for the manufacture of packing material similar to a quilting with such configuration.

In WO 96/40496 a machine is disclosed for the manufacture of packing material similar to a quilting with two designs of a configuration for the supply of papers continuous

An embodiment of the configuration (figures 9, 10) is based on a form of operation in which the role Continuous is pulled directly from the supply coil. To this end, the configuration contains an axis to receive a continuous paper supply coil comprising a plurality of layers of paper, a brown deflection roller the continuous paper and a separating device that has at least a first roller of guide and a second guide roller to separate the layers of paper. The deflection roller and guide rollers are arranged in a fixed place on a frame. In this way, the continuous paper pulled from the paper reel separates in the layers individual paper in advance of the conformation in the Packing material.

This configuration has the disadvantage of being they will produce load peaks in the paper layers when unrolling the Continuous paper not cushioning them. In order to try said load peaks, the continuous paper is pulled in the practice at a lower speed.

Another embodiment of the invention (figures 1 to 3) It is based on a different form of operation in which the role continuous is pulled from a supply reel is supplied by the means of a unit with a uniform tension. For this purpose, the configuration includes a tension roller movable 70, two guide rollers 67, 68 fixed location, three 75 to 78 fixed-position spacer rollers and a roller movable bending 118. The tension roller 70 is arranged in shape pivotable to standardize the voltage differences that arise during unwinding of the paper reel. In conjunction with the continuous paper form that takes place in the form of a loop on the guide rollers 67, 68, the effects are damped during the start and stop of the supply coil, and by both a uniform tension is maintained in the continuous paper.

This configuration has the disadvantage that, as a result of the form of operation, a additional supply unit for continuous paper, which has the consequence of more complexity and a higher cost.

The invention is based on the object of improving the known configurations and the machines in which the configuration, by distribution with a supply unit special and higher output speed, which can be achieved at through the movable configuration of the guide rollers.

The solution of these objects is exposed in the independent claims 1 and 9.

Additional developments found are the subject of the dependent claims.

The advantages that can be achieved with the invention are essentially the visible fact that the burden of layers of paper during deflection and separation by settings are reduced to a level appropriate for the paper, because paper layers can be supplied at high speed and because the production capacity is improved. Further, there is the possibility of increasing the scope of use by means of a third layer of paper of the same design or different.

The invention will be explained subsequently with Reference to the attached drawings.

The wheels 7 are mounted on the frame in order to move the machine.

The paper supply configuration Continuous 8 is mounted on frame 1. The configuration includes a shaft 11 for the supply coil 12 with continuous paper which It consists of two layers of paper, a baffle roller 13 for the continuous paper and a separating device 14, in order to separate The layers of paper. The shaft 11 is mounted on the side parts 5 of the frame 1. The deflection roller 13 is mounted on a elongated groove 15, which is arranged vertically in each side part 5. The separating device 14 includes a first guide reel 17, which remains in contact with the paper continuous 8 and aims to raise the paper layer and reflect on it, a second roller 18, which is intended reflect the second layer of paper and a third roller 19 which is associated with the first guide roller 17. The first and second guide rollers 17, 18 are each mounted in a elongated groove 16, which is arranged vertically in each side part 5. The elongated groove 16 is advantageously made of The same way. The third roller 19 is mounted in holes that they are formed on the side parts 5. The first guide roller 17 is located on the third roller 19 with the continuous paper 8 between them. Rollers 17, 18 and 19 are made of plastic, which can be electrostatically charged and by means of spikes metal bearing

Additionally, a brake band is provided 20 and a brake lining 21. The brake band 20 is made Flexible steel For the insertion of paper layers in the device 2, a convergence axis 22 is provided, which it has a convergence section 23 with the wall sections 24 curved (figure 3) on the narrow side.

For the preparation a reel of supply 12 within the frame 1. As mentioned, the bearing shields 5 are fixed in a free vertical way in the frame for this purpose, so that the deflection roller 13, the first and second guide roller 17, 18 and the third roller 19, are freely accessible from the side of the control panel 3. The supply reel 12 provided with the axis 11 is placed on bearing shields 5 and engages inside the cut provided for shaft mounting. In this position, the supply reel comes into contact with the brake band so that a unwanted unwinding of continuous paper. The continuous paper 8 is introduced through the deflector roller 13 between the first guide roller 17 and the third roller 19.

The paper layers of the continuous paper are separated on the guide rollers. Subsequently, the ends of the layers of paper are deformed manually and inserted into the shaft inside the device 2. As a result of the paper trend for resume its original form, paper layers expand waters below the convergence section 23 formed on the axis 22 and they return using the edges formed in section 23. This has the advantage that a machine so prepared simply starts the manufacture of packing material similar to a quilting when the machine is activated without further measures that have to be exercised by the operator.
