Definitions

  • the invention relates to a cleaning device for removing blasting media deposited on blasted workpieces, with a conveyor track for the blasted workpieces and with a rotatingly drivable brush roller arranged above the conveyor track and brushing the surface of the workpieces, which together with a brush drive unit is height-adjustable relative to the conveyor track.
  • a cleaning device of the aforementioned type is preferably used in a runway blasting system.
  • This essentially consists of a continuous blasting cabinet in which one or more blasting areas are present. After passing through the blasting areas, blasting media, in particular quartz sand, are on the workpieces and must be removed. For this purpose, the workpieces pass through a cleaning device by means of which the abrasive that may have remained on the surface of the parts is removed.
  • a cleaning device is known from DE-GM 75 20 863.
  • the workpiece to be cleaned is brushed off by two opposite, rotating brushes. Any remaining abrasive particles are blown off by a blowing device.
  • Each brush can be adjusted in height and at an angle to the working plane using screw spindles and piston rods so that it is the one to be exposed Can coat the surface of the parts well.
  • the lever arm that carries the partial brush also serves as a carrying device for the drive motor for rotating the brush.
  • the disadvantage is that the brush unit is designed as a rigid, fixed block.
  • the brushes, which wear out relatively quickly, are therefore very difficult to replace.
  • a cleaning device of the type mentioned at the outset which is characterized in that the brush roller and drive unit are arranged to be vertically adjustable along a substantially vertically arranged guide device and can be lifted out of the working area of the cleaning device from the head region of the guide device.
  • the invention therefore essentially comprises the principle of making the brushes adjustable along a vertical guide in a work area, so that they can be easily adapted to different material heights.
  • the guide device and the brush unit are designed such that when the cabin roof is open, the brush can be removed upwards by means of a lifting device.
  • a guide device suitable for the invention preferably consists of a guide arranged at each end of the roll, and a roll guided therein connected with the leadership.
  • the use of a cable pull also has the advantage that the lifting height of the cable pull can be made height-adjustable. This is done, for example, in that a pulley belonging to the cable, which is attached to the head of the cabin during the normal work of the cleaning device, is moved upwards by a linkage with the cabin roof open, the cable not needing to be flipped over. Rather, the brush roller can be pulled up out of the guide with the rope so that it hangs freely and is easily accessible, for example for maintenance work. If the brush roller as a whole is to be replaced due to wear, the brush is only suspended from the cable pull and gripped and carried away by a crane device. A new brush can then easily be latched in and fitted back into the guide when the cable is lowered. After removing the height adjustment with the deflection roller, the cleaning device is ready for normal operation again.
  • An additional blow-off device is usually present for such cleaning devices. It is proposed to synchronously adjust the height thereof and to function as a counterweight by means of a cable with the cable of the brush unit. Details of this are described in further subclaims and are explained in the description.
  • a cleaning device for removing blasting media deposited on blasted workpieces 31 is described below with reference to FIGS. 1 to 3.
  • the cleaning device is usually part of an integrated cleaning line, the individual stations of which are connected by a conveyor track 32 - here a conveyor belt - running through all stations.
  • the stations are shielded by a cabin 21 which is stiffened by rods 4.1, 4.1, 4.3, 4.4, 5.1, 5.2, 5.3, 5.4.
  • a cleaning device which comprises a brush unit 1 which is arranged above the conveyor track 32 and which, together with a brush drive motor 2, is vertically adjustable relative to the conveyor track 32.
  • guides 30.1 or 30.2 are provided on the brush axis ends, which are designed as U-profiles, in each of which a guide roller 18 is guided in a rolling manner.
  • the parts 30.1, 30.2 and 18 form the guide device 30.
  • the brush unit 1 comprises a brush roller 1.1 which can be driven in rotation, a brush housing 22 which covers the brush roller 1.1 at the top, and the drive motor 2 which is flanged directly onto the brush roller 1.1.
  • the brush unit 1 is suspended on two traction ropes 6.1 and 6.2, which are mounted over two in the head of the cabin 21 Deflection pulleys 8.1 and 8.2 are placed.
  • the traction ropes 6.1 and 6.2 are continued up to two corresponding rope drums 10.1 and 10.2.
  • the cable drums 10.1 and 10.2 are arranged with further cable drums 11.1 and 11.2 on a common shaft 15, which in turn is reversibly driven by a drive motor 12.
  • the shaft 15 is supported in the side walls of the cabin 21.
  • the cable drums 11.1 and 11.2, which are located on the same shaft 15, are each occupied with a pulling cable 7.1 and 7.2, which are placed over deflecting rollers 9.1 and 9.2 and with which blow-off devices 3 are carried in a height-adjustable manner.
  • the joint drive of the pulling ropes 6 and 7 accordingly results in a synchronous height adjustment of the brush unit 1 and blow-off device 3.
  • the entire brush unit with drive motor can be adjusted in height in its entirety. This enables an adaptation to different material heights in a simple manner.
  • the deflection rollers 8.1 / 8.2, as can be seen particularly from FIG. 2, are attached to the ends of a brush deflection shaft 13. Together with the cable drums 10.1, 10.2 on the common shaft 15, a crane-like device results which is able to raise and lower both the blow-off device 3 and the brush unit 2.
  • the height of the brush unit 1 can be adjusted such that the brush 1.1 is optimally adjusted to the workpieces 31.
  • the blow-off device 3 can also be optimally adjusted accordingly, so that residual abrasive particles are blown off cleanly by a cross-flow blower 26. So no If the dust escapes, the cleaning system works in recirculation mode. Whirled up abrasive particles are caught by a filter 20, which is arranged in front of the blower housing 23, when the air is sucked in.
  • both assemblies 1 and 3 can be completely and continuously raised and lowered by the shaft 15 and the cable pulls already described.
  • a suitable extension rod 4.1 'or 4.2' is attached to the rods 4.1, 4.2. This attachment can also be accomplished by telescoping apart. Corresponding locking elements (not shown) are provided.
  • the existing deflection rollers 8.1, 8.2 are, as FIG. 3 clearly shows, then fastened accordingly at the uppermost end of the extension 4.1 '.
  • the cable pull 6.1 is placed over the pulley 8.1. Stability increases that the deflection shaft 13 forms a crossbar.
  • the traction cable 6.1 is pulled off the cable drum, and a corresponding decoupling can be carried out between the shaft 15 and the cable drum.
  • the complete brush unit 1 with the drive motor can then be moved out of the cabin of the cleaning device upwards. So that this moving out is possible, the cabin upper part 25 is designed above the brush unit 1 so that it can be opened.
  • the brush unit 1 and the drive unit 2 also via deflection rollers by means of a separate drive roller (not shown) is pulled up. In both cases it is possible to carry out repair and maintenance work on the now exposed brush unit. It is also possible to lift the brush 1.1 out of the housing in a simple manner, for which purpose a special crane is required.
  • extension rod 4.1 with a gallows-like cross-beam which is provided with a vertical axis of rotation about a pivot point located in the head, so that the brush as a whole is pivoted and lowered onto the floor outside the cabin can.
  • the brush unit 1 is lowered again into the guide and inserted into the guide and initially fixed there. Now the pulleys 8.1 and 8.2 can also be moved and then the extension rods 4.1 ', 4.2' can be removed. The pulleys 8.1, 8.2 and the ropes 6.1, 6.2 get their original position again. After final adjustment of the brush unit 1 and the drive unit 2, the cleaning device can be put into operation again.
