Definitions

  • the present invention relates to a device according to the preamble of claim 1.
  • a device is known for example from CH-PS 559 691.
  • a further supply spool and guide rollers for a second winding belt are arranged above the conveyor belts arranged in a stationary manner and above the flat structures and below these the winding belt feeding or taking away the winding belt.
  • the two winding belts which are practically as wide as the flat structures, form a conveyor gap in which the flat structures are clamped and, together with the winding belts, fed to the driven winding core, and wound up together with the winding belts.
  • the length of the rocker-type conveyor belt arrangement is to be dimensioned to a comparatively significant value, with the result that the space requirement of the devices with a bearing point arranged at a constant height for the winding core is relatively large and direct drive of the conveyor belt arrangement is practically inevitable.
  • the device 10 shown in the drawing has a base 11 on which, on the one hand, two upright guide columns 12, 13 are anchored and, on the other hand, a conveyor belt arrangement 14, only shown schematically, is mounted.
  • the deflection roller 15 of the conveyor belt arrangement 14 connects to a conveyor 16, of which only the end or the beginning (depending on whether winding or unwinding) is shown in FIGS. 1 and 3.
  • a carriage or carriage 18 is mounted, which is displaceably guided by rollers 17 and from which the drive members for an essentially hollow cylindrical winding core 19 protrude.
  • These drive members comprise two drive wheels 20, 21 which drive the winding core 19 from the inside in a frictional engagement, and a freely rotatably mounted tensioning roller 22 which holds the winding core 19 in contact with the drive wheels 20, 21 EP OS 0161569 described in detail.
  • a differently designed drive for the winding core which does not necessarily have to be hollow cylindrical, can also be provided.
  • a nut piece 23 (FIG. 2) is anchored on the carriage 18 and is penetrated by a threaded spindle 24 parallel to the guide columns 12, 13.
  • the threaded spindle 24 is attached by means of a stationary motor 25, for example on the guide columns 12, 13, which is only indicated schematically drivable, so that the motor 25 of the carriage 18 can be moved and held practically continuously over the entire height of the guide columns 12, 13.
  • a motor 26 flanged to the carriage 18 is coupled to the drive wheel 21, while the drive wheel 20 is positively coupled to the drive wheel 21 via a chain drive 27.
  • the conveyor belt arrangement 14 is arranged in a frame 28, indicated only schematically in FIG. 1, which is pivotally mounted about the axis of the deflection roller 15 and carries a further deflection roller 29 at its end which appears on the right in FIG. 1.
  • the two deflection rollers 15 and 29 are freely rotatably supported and looped around by a pair of comparatively slack conveyor belts 30, 31 (FIG. 2).
  • a further deflecting roller 32 is freely rotatably mounted on the frame 28 in a manner not shown, which has a winding belt 34 pulled off a supply roller 33 or wound onto it and guided over the deflecting roller 29 brings to the height of the upper run of the conveyor belts 30, 31 and runs in the same direction with them.
  • the frame 28 and thus the conveyor belts 30, 31 and also the winding belt 34 are pushed upwards by means of a spring 35, for example a gas spring, so that the comparatively slack conveyor belts 30, 31 are pressed against the circumference of the winding W located on the winding core 19 and wrap it over a comparatively large arc length. If the winding W is driven via the winding core 19 in one or the other direction of rotation, the conveyor belts 30, 31 thus run along and the winding belt 34 is pulled off the supply roll 33 or wound onto it.
  • a spring 35 for example a gas spring
  • the supply roll 33 is positively coupled via a chain drive 36 to a torque-controlled machine 37, which will be returned in particular in connection with FIG. 3.
  • the device is suitable for producing coils of the most varied diameters, and in addition finished coils W, regardless of their diameter, can be raised by means of the threaded spindle 24 to such an extent that they can be pulled through from the side opposite the carriage 18 ( 2 from the right) transport vehicle (for example by a forklift) can be removed from the drive wheels 20, 21 and the tensioning roller 22 and transported to an intermediate storage location.
  • Fig. 1 the bottom and top positions of the winding core 19 can be seen with dash-dotted circles.
  • the direction of rotation of the winding W is indicated by the arrow 38 when winding and the arrow 39 indicates that when it is being unwound.
  • FIG. 3 largely corresponds to FIG. 1, but in this FIG. 3 a block diagram of the electrical circuit is superimposed.
  • the symbol M 1 corresponds to the motor 26, the symbol M 3 to the motor 25 and the symbol M 2 to the torque-controlled machine 37.
  • a transmitter 40 for example a tachometer generator, is coupled to the illustrated deflection roller of the conveyor 16, which generates a “target” signal relating to the speed and the conveying direction of the conveyor 16. This signal reaches a comparator and feed stage 42 via a line 41.
  • a transmitter 43 is also coupled to the deflection roller 32 for the winding tape 34, which generates an “actual” signal with respect to the actual peripheral speed and the direction of rotation of the winding W.
  • This actual signal is fed to the comparator and feed stage 42 via a line 44.
  • the motor 26 (M 1) can be a reversible DC machine or a frequency-controlled pole-changing asynchronous motor.
  • the conveyor belt arrangement 14 is assigned two buttons 46, 47, for example light barriers, which detect the momentary installation of the upper run of the conveyor belts 30, 31. If the button 47 responds, the motor 25 (M 3) of the threaded spindle 24 is switched on via the line 48 in the sense of lifting the carriage 18 (and thus the roll W) and remains switched on (when winding up) until the button 46 appeals. When the roll W is unwound, the buttons 46, 47 swap their roles. The motor 25 (M 3) can, however, also be switched on and off via a switch 49, which is only indicated schematically and bridges the buttons 46, 47. A reversible and pole-changing asynchronous machine has proven to be expedient for the motor 25 (M 3).
  • the motor 25 (M 3) is switched on when a finished roll has to be raised to the highest position for takeover by a transport vehicle (as mentioned) or when an empty roll core 19 has to be lowered so far that it touches the conveyor belt arrangement 14 .
  • the winding tape 34 is kept under as constant a tension as possible when winding the winding W. Therefore, the supply roll 33 is to be braked in accordance with its own diameter so that the winding tape receives the desired tension (and elongation) between the run-off point from the supply roll 33 and the run-up point on the roll W.
  • the braking torque to be exerted on the supply roll 33 is of course dependent on its current diameter. Therefore, the supply roll 33 is assigned a diameter sensor 50 which controls the torque-controlled machine 37 (M 2) via a control line 51 and a control stage 52.
  • This torque-controlled machine 37 (M 2) is expediently a torque-controlled servo DC machine which can be switched both as a motor (drive) and as a generator (brake).
