Definitions

  • the present invention also relates to a working device, in particular on a textile machine, with a working member which can be moved back and forth along a rail.
  • the working organ can be a cleaning device which can be moved back and forth along the rail over one or more textile machine (s) placed one behind the other in the longitudinal direction in order to periodically clean it of dust and flight by means of blowing and suction air.
  • the blowing and suction air is generated by a fan in the movable working element and guided to the cleaning zones by air guiding elements.
  • Optical or electromechanical detectors can be present, which stop the movement of the work organ and, if necessary, reverse the direction of movement when obstacles are detected.
  • a drive device has already become known in which the traveling movement of a car with a fan impeller takes place by means of an endless transmission member which is connected to a stationary drive motor. (DE-B 1 510 720).
  • the object to be achieved by the invention is to supply the control, which is arranged on the work organ and serves to detect obstacles, in such a way that no drag capsules or mechanical contact elements subject to wear are required.
  • the movable working member is equipped with transmission members which are comprised of a drive belt and which are each composed of three pulleys arranged with the same axis, the individual pulleys of the same transmission member differing in diameter from one another.
  • the embodiment described in claim 3 is particularly recommended, since the mentioned design permits a very simple change of direction of the work organ which can be moved back and forth, the drive of the generator being in no way influenced by the change of direction and not suffering an interruption.
  • the proposed working device is designed as a mobile cleaning device which is run along one or more testile machines, such as e.g. Spinning or twisting machines, can be moved back and forth to periodically clean them of dust and flight by means of blowing and suction air.
  • the working device designed as a cleaning device is designated by 1. It has a carriage 3 which can be moved on two horizontal rails 2 and on which transmission elements 16, 17, 18, a fan 5 and a control device 6 with limit switches 7a and 7b are arranged. Furthermore, four sensors 8a to 8d are also provided, all of which are connected to the control device 6 by lines 9.
  • Air guiding elements 10 are connected to the housing of the fan 5 and are arranged on both sides of the drive device 1 and extend approximately to the bottom.
  • These air-guiding elements 10 delimit cleaning zones 4, in which the textile machines, which are generally designated 11, are cleaned by compressed and suction air.
  • the working device 1 is moved back and forth along these machines 11 in such a way that the machines 11 are located between the air guiding elements 10 in the cleaning zone.
  • an electric motor 12 is arranged in a stationary manner at one end of the path to be covered by the working device (FIG. 3), a transmission element in the form of an endless drive belt 15 being stretched between the drive pulley 13 of the electric motor 12 and a deflection pulley 14 at the other end of the working path is.
  • the endless drive belt 15 also wraps around the three transmission links 16, 17, 18, as will be described below.
  • Each transmission link 16, 17, 18 is made up of three pulleys 16a, b, c; 17a, b, c and 18a, b, c together, the individual pulleys of the same transmission member differing in diameter from one another.
  • the dimensions are chosen so that the lowest pulley 16c is smaller in diameter than the uppermost pulley 16a, which in turn is smaller than the central pulley 16b.
  • the conditions regarding the transmissions are exactly the same links 17 and 18.
  • the arrangement is such that the rear run 15a of the drive belt is constantly guided over the belt pulleys 16a, 17a and 18a, which includes this along a serpentine line, while the front run 15b optionally over the lower belt pulleys 16c, 17c, 18c or over the middle disks 16b, 17b and 18b or over the upper disks 16a, 17a and 18a.
  • this front run 15b comprises the disks 16, 17, 18 opposite to the rear run 15a.
  • a changeover device 19 which consists of an electromagnet 20 and a guide element 21 which surrounds the strand 15b and can be displaced in the arrow directions 22 by the electromagnet 20.
  • a line 23 connects the electromagnet 20 to the control device 6.
  • an electric motor could also be used.
  • the strand 15b is changed from the lower pulleys 16c, 17c, 18c to the middle pulleys 16b, 17b, 18b with the aid of the changeover device 19, a speed difference which is effective in the other direction is produced in order to produce an opposite movement.
  • the pulleys 16a, 17a, 18a are each provided with a further groove for guiding the strand 15b, it is possible to move the strand 15b completely upwards onto the pulleys 16a, 17a and 18a. In this case, the drive belt 15 runs, but the carriage 3 does not move.
  • the power supply to the control device 6 takes place with the aid of a generator 24 which is built into the transmission element 16.
  • 4 shows the detailed structure of the generator 24 in connection with the transmission element 16.
  • the generator 24 has a shaft 28 with the pulleys 16a, 16b, 16c.
  • the pole wheel is designated 29 and the armature winding 32. Due to the rotation of the transmission member 16, the magnet wheel 29 of the generator 24 also rotates and current is induced in the fixed armature windings 32.
  • the control device 6 is supplied with power by a line 25, regardless of the direction of movement of the carriage 3. In the manner described, it is also ensured that there is no power failure even when the carriage 3 is stationary.
  • the limit switches 7a and 7b arranged on the carriage 3 cooperate with stops present at both ends of the movement path of the carriage 3 and are connected to the control device 6 by lines 30, 31. In the area of these stops, one of the limit switches 7a or 7b is changed over, as a result of which the control device 6 actuates the electromagnet 20 to adjust the guide member 21 for the drive belt.
  • the strand 15b is shifted from the lower pulleys 16c, 17c, 18c to the middle pulleys 16b, 17b, 18b, which are larger than the upper pulleys 16a, 17a and 18a, which are wrapped by the strand 15a, so that a change of direction in the movement of the Wagens 3 takes place.
  • the sensors 8a to 8d are arranged on the air guiding elements 10, and e.g. are designed as ultrasonic sensors, which also cause a reversal of the carriage 3 together with the air guide elements 10 when the air guide elements 10 approach an obstacle.
  • the sensor 8a to 8d which detects the obstacle, sends a signal to the control device 6, which influences the electromagnet 20 for converting the guide member 21 in the manner mentioned, as a result of which the direction of movement of the carriage 3 is changed. In this way, collisions of the air guide elements with obstacles that lie in the path of movement of the air elements can be avoided.
  • the reliability of the sensors 8a to 8d can be increased further and the possibility of incorrect switching can be excluded if only the sensors in the direction of travel are switched on.
  • the energy-intensive drive for the carriage 3 and for the fan 5 takes place through the endless drive belt 15, which is moved by the stationary electric motor 12, while the minimally required current is generated with the aid of the brushless generator 24 arranged on the movable carriage 3 .
