Definitions
- the invention relates to a device for temporarily storing a band-shaped material.
- Dancer rollers are also used for the intermediate storage of a band-shaped material, as a result of which the band-shaped material can be processed further in the order of input.
- the device essentially comprises a series of stationary rollers arranged parallel to one another, below which a series of movable rollers arranged parallel to one another are arranged.
- the strip-like material is guided over a first roller of the fixed row to a first roller of the movable row and from there is fed back over a second roller of the upper row to a second roller of the lower row and so on until the strip-like material is discharged again via a last roller of the upper row.
- the rollers of the lower row move downwards uniformly, so that thereby the band-shaped material is temporarily stored. If the strip-like material is discharged faster on the last roller of the upper row than is fed via the first roller of the upper row, the rollers of the lower row are moved upwards by the tensile force of the strip-like material. In the quasi-stationary state, ie the feed and discharge speeds are the same, the position of the rollers in the lower row does not change.
- the disadvantage of the known device is the large space requirement with only limited storage capacity.
- the object of the invention is to create an intermediate store for strip-like material which requires little space and has a large storage capacity.
- a rotatably mounted, hollow outer coil body in which a hollow inner coil body is arranged in a stationary manner, the outer coil body having at least one second passage opening and the inner coil body having at least one second passage opening for the strip-shaped material, and the arrangement of a deflection device in the interior of the inner bobbin, wherein the mutually displaceable band-shaped material is wound or unwound upon rotation of the outer bobbin on the latter and the inner bobbin, the band-shaped material being led out of the interior of the inner bobbin by the deflection device space-saving device for temporarily storing a band-shaped material with high storage capacity.
- the storage capacity of the device is only limited by the distance between the inner coil former and the outer coil former.
- the outer coil body and / or the inner coil body as a shaft ring with rotatable shafts, the frictional resistance on the surfaces of the respective coil bodies is reduced, so that the band-shaped material is not exposed to excessive tensile forces.
- the surface of the outer and / or inner coil body can also be designed as a roller surface, the roller being movably inserted into a base body forming the surface of the coil body or arranged together on individual axes.
- the surface consists of sintered material and an air flow is generated radially outwards through the sintered material inside the coil former. This causes the band-shaped material to float on an air cushion.
- the strip-shaped material can be deflected without tension by the arrangement of a pull-off motor inside the inner coil body.
- FIG. 1 shows a side view of a device for intermediate storage of a band-shaped material in the initial state
- FIG. 2 shows a side view of a device for intermediate storage of a band-shaped material in the partially wound state
- FIG. 1 shows a side view of the device 10 for temporarily storing a band-shaped material 12.
- a hollow inner bobbin 16 is arranged concentrically, which is arranged in a fixed position by a fixed bearing 18.
- the outer coil body 14 and the inner coil body 16 are formed by radially arranged shafts 20 which are rotatably mounted and are arranged at an equidistant distance from one another. Between two adjacent shafts 20, passage openings 22, 24 are formed in the outer and inner bobbins 14, 16 for the passage of the band-shaped material 12.
- a deflection device 26 is arranged, which by two 90 ° deflections 27 is formed to lead the band-shaped material 12 out of the interior of the inner bobbin 16.
- the outer coil body 14 is acted upon by a drive 28 with a drive belt 30 with a constant torque.
- the band-shaped material 12 is threaded through an inlet 32 formed by rollers into the passage opening 22 of the outer bobbin 14, passed through the passage opening 24 into the interior of the inner bobbin 16, led out of the interior of the inner bobbin 16 via the deflection device 26 and an output 34 realized by rolling.
- the storage capacity of the device 10 for temporarily storing a strip-shaped material 12 is only limited by the distance between the inner coil former 16 and the outer coil former 14.
- the static state shown is established. If the band-shaped material 12 is discharged at the outlet 34 at the same speed as it is fed to the inlet 32, the tensile stress of the band-shaped material 12 acts on the outer coil former 14 with a torque which counteracts the torque of the drive 28, so that the outer bobbin 14 remains at rest. Will that band-shaped material 12 stopped at the outlet 34 and released at the input 32, the outer coil former 14 is set in rotation by the torque of the drive 28, whereby the band-shaped material 12 is wound onto the outer coil former 14. A part of the band-shaped material 12 is deflected on the shaft 20 of the passage opening 22 onto the inner bobbin and wound thereon.
- the band-shaped material 12 which is wound onto the inner bobbin 16 is supplied from the outer bobbin 14 through the passage opening 22.
- the band-shaped material 12 on the outer bobbin 14 and the inner bobbin 16 moves against each other.
- the outer coil body 14 and the inner coil body 16 are each completely wrapped once by the band-shaped material 12.
- the band-shaped material 12 is supplied by the outer coil body 14 along the length of the circumference of the inner coil body 16 for the inner coil body 16 so that after the complete rotation the outer coil body 14 and the inner one Coil bodies 16 are each wrapped twice, the band-shaped material 12 fed to the device 10 first being located on the inner coil body 16.
- FIG. 2 shows a side view of the device 10 for the intermediate storage of the strip-shaped material 12 with the input 32 and the output 34 released. Due to the torque of the drive 28, the band-shaped material 12 is wound from the inlet 32 clockwise 36 onto the uppermost layer of the band-shaped material 12 already wound on the outer spool 14. At the same time, part of the strip-shaped material 12 located directly on the surface of the outer coil former 14 is unwound in a clockwise direction 36, passed through the passage opening 22 into the interior of the outer coil former 14 and counterclockwise 38 to the uppermost layer of the layer on the inner coil former 16 located band-shaped material 12 wound.
- a pulling motor exerts a tensile force on the band-shaped material 12 at the outlet 34, so that the band-shaped material 12 located directly on the surface of the inner bobbin 16 is unwound in the counterclockwise direction 38 and via the 90 ° deflections 27 of the deflection device 26 is first led out of the interior of the inner bobbin 16 in FIG. 2 perpendicular to the paper plane and then deflected in a plane parallel to the paper plane in FIG. 2 to the entrance 32.
- FIG. 3 shows a top view of the device 10.
- the band-shaped material 12 is led vertically out of the interior of the inner coil former 16 and deflected by the second deflection 27 into a plane parallel to the plane of the supplied band-shaped material 12 at the entrance 32.
- a preferred field of application of the invention is printing technology.
- the performance of an overall system containing a printer can be increased. Stopping a subsystem, e.g. of the printer, does not necessarily have to lead to a stop of the entire system. This increases the overall throughput in the overall system and thus its performance.
- the performance of such an overall system which does not contain subsystems processing an endless web at the same time cycle, can be increased by the invention in that a "first-in-first-out buffer" implemented according to the invention is connected between the subsystems.
