Description

moving 3 cleaning elements 4 which are rigidly fixed to the shaft. The movement of the workpieces in the vertical plane is limited by the fixed lower support rollers 5 and the upper rollers 6, which are mounted with the possibility of adjustment in the vertical plane, which allows reconfiguration from one part size to another. At the inlet and outlet of the stripping device, receiving tables 7 and 8 are attached to the frame 1.

The drive of rotation and vertical movement 3 of the cleaning elements is a single-stage gearbox that can rotate around the drive shaft 9. on which two gears 10 and 11 are mounted with a different number of teeth. t Gear 10 is connected to gear 12, the hub of which, by means of a spline joint with the shaft of the cleaning element 4, transmits rotation to the latter.

The gear 11 is connected to the gear wheel 13, the end of which is a cam supporting the pusher 14, which is capable of translational movement along the splines of the gear wheel 12, inside which it is located. The shaft of the cleaning element 4 is supported by the pusher 14 and is capable of reciprocating together with the pusher 14 along the splines of the gear 12, from which it receives rotational movement. On top of the shaft of the cleaning element 4 is installed in the sleeve 15 of the lever, the housing 16 of which through the shaft 17 is fixed coaxially to the drive shaft 9 of the drive of rotation and vertical movement 3 of the cleaning element. The lever is mounted to rotate in a groove in the upper part of the frame around the shaft 17. The sleeve 15 is mounted in the housing 16 on the rolling bearings and allows the shaft with the cleaning element 4 to rotate and reciprocate. A cup 18 is attached to the flange of the sleeve 15, in which a spring 19 is located, pressing the cleaning element 4 against the drive follower 14 of the rotation and vertical movement 3 of the cleaning elements.

The housing 20 of the drive of rotation and vertical movement of 3 cleaning elements and the housing 16 of the lever are interconnected by a strip 21. The clamping mechanism 22 of the cleaning elements 4, pivotally mounted on the frame 1, is connected to the strip 21, which is subjected to the pressing of the cleaning elements by turning around shafts 9 and 17. For sealing, the mechanisms and treatment zones are closed by doors 23.

The device operates as follows.

After the device is turned on, roller rotation drives (not shown) are turned on.

and an engine 24 of rotation and vertical movement mechanisms 3 of the treatment elements. The rotation from the engine 24 through the V-belt transmission is transmitted to the shaft 9, which through the gear 10 into the gear

the wheel 12 transmits the rotation to the shaft with the cleaning element 4. The gear 11 transmits the rotation to the gear 13. The vertical movement is obtained due to the difference in angular velocity of the pusher 14 and

the cam of the gear 13. In this case, the pusher 14 rises or falls and thereby transmits vertical movement to the cleaning element 4.

After the drives are turned on, a stack of flat parts is laid on the receiving table 7, from where they are transferred one by one to the device until they are caught by the drive rollers 2. The drive rollers 2 move the parts to the treatment area where they are protected by cleaning elements, and then move to the receiving table 8. Press of the cleaning elements 4 to the workpiece is carried out by the clamping mechanism 22, while the cleaning element rotates around the drive shaft 9 of the drive of rotation and vertical movement and the shaft 17 of the lever.

The application of the proposed design will improve the reliability of the device by eliminating the lateral movement pneumatic cylinders, additional limit switches, reversing valves and other equipment, i.e. significantly simplify the system of automatic coordination and control of the mechanisms of the device, and thereby its reliability. The reduction in the occupied production area is achieved by finding the part during processing in

upright position. Improving the convenience of service is manifested in that access to replaceable cleaning elements is provided from the side and not from the top, as in the prototype, when it is necessary to remove the support to change the lower cleaning element.

Claims (1)
