Definitions

  • the invention relates to a multi-station beam processing machine as characterized in the preamble of claim 1.
  • a multi-station beam processing machine of the type mentioned in the preamble has become known from US-A-2 629 207.
  • This document shows a blasting machine for lithographic plates, the workpieces being attached to the circumference of rotatable drums.
  • Five pick-up stations each have such a drum, which are cyclically brought about a horizontal axis from a loading station in two beam treatment stations and from there to an unloading station.
  • the loading and unloading station are arranged opposite each other in the central area of the conveyor wheel and have no drives for rotating the workpieces or the drums.
  • Another multi-station beam processing machine has become known from DE-A1-2813705, in which the workpieces, such as. B. engine blocks or cylinder heads, in the beam area lying separate loading and unloading in one-sided open, formed by horizontal legs carrier.
  • the blasting wheels arranged in the upper area of the blasting housing also hit the workpiece passing through the lower area undefined, which is why the blasting wheels must be switched off to unload and unload the workpieces.
  • the disadvantage here is that none of the rotating workpieces is blasted during this period, which overall increases the throughput time for a workpiece and the machine has poor efficiency.
  • the workpieces are not properly held axially in the carriers, which enables them to be displaced during the passage and thus to faults.
  • DE-C3-2212487 has disclosed a conveying device by means of a centrifugal blasting system, in which the workpieces are held by means of support yoke legs hanging in guide rails by means of these on both end faces and are conveyed in a rotating manner by means of a centrifugal blasting machine.
  • this conveyor is not connected to a multi-station beam processing machine mentioned at the beginning.
  • a centrifugal jet machine loaded with such a conveyor device has large dimensions in relation to its performance.
  • the object of the present invention is to create a compact multi-station beam processing machine of the type described at the outset, in which a high workpiece throughput and a uniform beam effect are achieved even on different workpiece shapes with secure or immovable workpiece holder during the beam processing with the shortest possible idle times. Automatic loading and unloading should also be possible.
  • the holding device which is tensioned at the front by means of spring force, a fixed axial support is achieved despite accessibility of the blasting medium to the workpiece end faces and the possibility of receiving two workpieces in one receiving station, which are simultaneously introduced radially into the receiving station with a short loading time.
  • Automatic loading and unloading is made possible with the simple construction by the actuating elements arranged in the loading and unloading station which engage in the holding part in order to release the workpiece clamping.
  • the assignment of a rotary drive for the workpieces at each station enables different speeds, directions of rotation and downtimes of the workpieces in the individual stations, as well as maintaining a specific stop position in the loading and unloading station.
  • the multi-station beam processing machine has a beam housing 1, in which a vertically standing conveyor designed as a wheel 2 is arranged so as to be rotatable about a horizontal axis 3, the wheel 2 being preferably drivable by a geared motor 4.
  • the wheel 2 has three receiving stations 5 for workpieces 6 which are evenly distributed on the circumference and which can be brought into a loading and unloading station 7 and in two blasting treatment stations 8, 8a of the blasting housing 1 in cycles.
  • Each receiving station 5 is surrounded by walls 9 attached to the wheel 2, each of which form a closed blasting chamber 10 with the surrounding blasting housing 1 in the region of the blasting treatment station 8, 8a.
  • the walls 9 are composed of side walls 11 running perpendicular to the axis 3, approximately radially to the axis 3 and parallel to the axis 3 intermediate walls 12 with walls 12a running on the circumference.
  • grinding elastic seals can also be arranged on the strips 40.
  • the walls 12, 12a together with the side walls 11 form a cavity 42 in the wheel 2.
  • the receiving stations 5 each have two holding devices 13, 13a, one behind the other in the axial direction, which clamp the workpieces 6 at the end.
  • Each holding device 13, 13a consists of an axially displaceable holding part 14, 14a and an axially fixed holding part 15, 15a.
  • the holding parts 15, 15a of the two holding devices 13, 13a, which are located one behind the other, are interchangeably fastened on a common shaft 16, the shaft 16 being rotatably mounted in a bearing block 17 connected to the walls 12.
  • the holding parts 14 and 14a are each interchangeably fastened on a shaft 18, the shaft 18 being mounted axially displaceably in a bushing 19 but connected to it in a rotationally fixed manner. Between the sleeve 19 and the holding part 14, 14a, a spring 20 is arranged on the shaft 18, by means of which the holding part 14, 14a. is pressed against an end face of the workpiece 6. Each sleeve 19 is rotatably supported in the side walls 11 of the wheel 2.
  • the shafts 18 are provided at their outer end with a collar 21 which in the loading and unloading station 7 produces the operative connection of the holding part 14, 14a with a fixed actuating element 22, preferably a hydraulically or pneumatically actuated cylinder. This takes place in that the collar 21 moves into a T-slot piece 23 of the actuating element 22 when the wheel 2 is rotated.
  • each shaft 24 mounted in the side walls 11 is arranged within the walls 12, 12a, which are connected in a rotationally fixed manner to the bushes 19 or the shafts 16 by means of chain or belt drives 25.
  • a wheel 26 which is operatively connected in the loading and unloading station 7 and in the beam treatment stations 8, 8a with drive wheels 27 arranged there.
  • the wheels 26 and the drive wheels 27 can preferably be designed as friction wheels or as gear wheels.
  • the drive wheels 27 are each fastened to a gear motor 28, which is preferably adjustable in speed and reversible in the direction of rotation, by means of which the holding devices 13, 13a can be set in rotation in each station 7, 8, 8a.
  • a gear motor 28 which is preferably adjustable in speed and reversible in the direction of rotation, by means of which the holding devices 13, 13a can be set in rotation in each station 7, 8, 8a.
  • control disks 29 are fastened, which interact with a control element 30, preferably a limit switch, in the loading and unloading station 7 for the purpose of stopping the holding device 13, 13a in a specific loading and unloading position.
  • switchable control elements 30 can also be arranged by the control disk 29, whereby certain blasting treatment programs can be controlled depending on the respective position of the workpiece 6.
  • the blasting housing 1 has an opening 31 in the upper region, through which the loading and unloading station 7 is accessible from the outside for inserting and removing the workpieces 6 and which can advantageously be closed by a cover (not shown).
  • Centrifugal wheel units 32 are arranged on the side walls of the blasting housing 1, two of which are attached to a blasting treatment station 8 and 8a on one side.
  • the lower part of the blasting housing 1 is designed as a pit 33, in which a screw conveyor 34 is arranged for the removal of the blasting medium and the blasted particles.
  • the blasting housing 1 is fastened to a frame 35, in which the axle 3 of the wheel 2 is also rotatably mounted and to which the geared motors 28, the actuating elements 22 and the geared motor 4 are fastened.
  • the workpieces 6 can into the receiving stations 5 either only the front side by means of the holding parts 14, 15 disposed tips 36 are held (see Fig. 1 left) or the front side and the peripheral side by means of retaining t rush 14a and 15a arranged retaining arms 37 are held (see Figure .1 right).
  • the type of execution depends on the workpiece shape.
  • Two workpieces 6 are simultaneously brought by a loading device, not shown, through the opening 31 of the loading and unloading station 7 into a receiving station 5 and held there by means of the holding parts 14, 14a and 15, 15a in the holding devices 13, 13a by spring force.
  • the wheel 2 is then rotated through 120 °, as a result of which the workpieces 6 reach the first blasting treatment station 8 and, at the same time, the workpieces 6 are rotated by engaging the wheel 26 with the drive wheel 27 in order to treat them on all sides by means of centrifugal jets from the centrifugal wheel units 32.
  • the second Loading station 5 can be loaded with workpieces 6.
  • the wheel 2 After a further rotation of the wheel 2 by 120 °, the workpieces 6 come into the second blasting treatment station 8a and the third pick-up station 5 can be loaded with workpieces 6.
  • the wheel 2 is rotated again by 120 ° and the finished blasted workpieces 6 reach the loading and unloading station 7.
  • they are rotated again by means of the geared motor 28 arranged there in order to empty the workpiece cavities by drumming out of abrasive.
  • the blasted abrasive remains on the partition walls 12 of the receiving station 5 until it flows off into the group 33 when the wheel 2 continues to rotate.
  • the geared motor is switched off by means of the control disk 29 and the control member 30 so that the workpieces 6 remain in a certain removal position.
  • the shafts 18 are axially displaced against the pressure of the springs 20 and the holding parts 14, 14a are released from the workpieces.
