Description

The invention relates to a cleaning system for difficult to transporting workpieces, wherein the workpieces remain stationary and the cleaning booth is movable so that it is can move towards the workpiece and irradiate the workpiece from all sides.

The cleaning of heavy and / or large workpieces that are too heavy or too large to be carried on the usual II'ingebahn conveyor systems To be brought into a cleaning house, have already been processed in cleaning houses with centrifugal wheels, with The workpieces are loaded onto a trolley with a turntable outside the cleaning house and then driven into the cleaning house became. Another method requires a flap roof that, in the open position, allows the workpiece to be retracted on one Hall crane allowed to be suspended and the workpiece then up

is placed on a stationary turntable for processing, Both methods have the disadvantage that the processing cannot be done in one go, because the bottom is not accessible to the beam. The workpieces had to be turned during an interruption of the machining, which is very time-consuming for large individual pieces, the The hall crane is occupied and several people are required to put on the suspension equipment. Because of the risk of accidents and The obvious possibility of damage is usually with such manipulations of heavy pieces a responsible supervisor is also present. That Setting up and supporting such a workpiece on a turntable is often difficult because of the impacts when driving of the car or turning on the turntable, the falling or falling of such a piece from the car or a turntable causes expensive damage and long downtimes,

A cleaning system according to the invention avoids all these disadvantages, a movable cleaning booth can be moved to at least two workstations in the system where immobile ones Load-bearing options for the workpiece are provided, as well as connections for blasting medium inflow and outflow and an air extractor, whereby the movable cleaning booth consists of a on the floor or rails, straight ahead or on a circle, There is a mobile frame structure to which the cleaning booth with centrifugal wheels and doors is attached so that it can rotate around a vertical axis and is provided with a rotary drive. Furthermore

adjustable pulse triggers or pairs of pulse triggers provided that act on the rotary drive at certain points on the workpiece circumference during machining for the automatic generation of standstills or pendulum movements within the set pulse trigger pairs given limits,

An advantageous embodiment is that the transport device or devices for cleaned blasting media firmly connected to the mobile part of the cleaning system are and that the cleaning equipment for the abrasive and the air are arranged in a stationary manner with connections to the transport devices for blasting media and the Pipe for the exhaust air.

Further details of the invention are from the attached Drawings and the description as well as the claims can be found,

Fig. 4 shows a section across the cabin and foundation according to Fig, I,

In the drawings, a movable four-legged frame with rollers 2 is shown, from the workplace 6 to

209888/0017

Workplace 7 can be moved. In the center of the upper side, the frame carries a ball pivot bearing 3 », one part k of which is connected to the upper part 5 of the cleaning booth 8 and attached to this is the bucket elevator IO and the screw conveyor 11, The blasting media feed line 12 is guided to the distribution screw 13 through the hollow cabin suspension k , The blasting media reaches the turbines 15 through the downpipes 14, These are arranged in such a way that a workpiece 16, which is placed on a stationary frame 17, is irradiated from all sides when the cabin 8 rotates with the drive 18 via the toothed ring 19. A permeable at each workstation 6 and 7 in the periphery of the cleaning cabinet for beam center floor cover 20 allows the mixture of blasting agent with the impurities in the screw conveyor 21 falls, passes through a P screen 22 with waste Rütsche 23 freed from coarse particles blasting agent mixture to the bucket elevator 2k and Via its ejection into the abrasive cleaning device 25, the cleaned abrasive is fed via the line 26 to the screw conveyor 27, which has a closable removal point 28 and 29 at both workplaces 6 and 7. The funnel 30 for the bucket elevator 10 is located at the two workstations under the inlet 28 and 29, respectively. The cabin is sealed at the bottom by brushes 31 over the entire circumference. The cabin suction takes place through the pipe 32, which is on

Workplace 6 has a closable nozzle 33. Workplace 7 also includes the closable nozzle 34. The rooms below the corridor belonging to each workplace are sealed by the funnel walls 35 and 36. The air ducts 37 lead to a stationary filter system with a fan, which is not shown. The booth has on both Sides of double-leaf doors 38, which are indicated by 39 in dash-dotted lines in FIG. 1. The turning circle of the corners of the quadrangular Cabin 8 is 40 t with the dash-dotted line designated (see Fig. 3). There is a 4l slide under each workstation. A cam 42 that communicates with the cabin rotates, works together rait a pulse generator 45, the in a switch cabinet, not shown, the rotary drive 18 stops for an adjustable time via a time relay. The pair of locks 43 in a different plane than the pair of cams 42 arranged works together with a pulse generator 46, the motor of the rotary drive l8 in its with each actuation Reverses the direction of rotation, causing a pendulum by the angle dj 44 takes place. Squat or pulse generators are adjustable over the entire circumference and can be attached in any desired amount.

The work sequence is designed so that while the cabin is over the workstation 6 processed a memo l6, at the workstation 7 the previously processed workpiece is transported away and then a new workpiece is set up. So you can work on two or more stations at the same time, which significantly increases utilization by eliminating waiting tents, The workpiece is easily accessible from all sides and can
