Embodiment
Now by reference to the accompanying drawings 1-6 and concrete implementation step the invention will be further described.
The PLC control device of this cylinder play provided by the invention, comprise cylinder rolling ring 1, support roller 2, bearing of conveyor idler 3, orienting sleeve 4, cover plate 5, U-shaped seat 6, worm-wheel shaft 7, rolling bearing units 8, worm screw fixes stand 9, worm gear 10, worm screw 11, worm-wheel shaft supports stand 12, reductor 14, torque arm 13 and bolt 15, cylinder rolling ring 1 is supported by four support rollers 2, each support roller 2 is fixed in cylinder frame by two rolling bearing units 3, the tightness of the set bolt of bearing of conveyor idler is adjusted to bearing seat and can be produced under the effect of external force and slide, only need adjust one of them support roller during cylinder play.This device is by realizing the control to cylinder play to two position of bearings adjustment of support roller, the bearing of conveyor idler 3 of every side respectively connects an orienting sleeve 4, promote bearing of conveyor idler 3 by orienting sleeve 4 to move forward, each orienting sleeve 4 is arranged in a U-shaped seat 6, U-shaped seat 6 is provided with cover plate 5, and orienting sleeve 4 is connected by right-hand thread with worm-wheel shaft 7; Worm screw 11 is arranged on worm screw by rolling bearing units 8 and fixes on stand 9, and be also provided with the worm-wheel shaft be connected with worm-wheel shaft 7 below worm screw 11 and support stand 12, worm screw 11 connects worm gear 10, as shown in Figure 3, the worm and wormwheel in left side is left-handed, and the worm and wormwheel on right side is dextrorotation, and the rotation direction of both sides is contrary; The worm-wheel shaft that reductor 14 is arranged on right side by torque arm 13 supports on stand 12, and two worm shaft bearings of the left and right sides, two worm-wheel shaft support stands and U-shaped seat are all arranged in cylinder frame, and orienting sleeve 4 is fixed by bolt 15.
Described cylinder rolling ring 1 place is provided with position detecting element, position detecting device element connects PLC by input block, PLC connects warning device and topworks etc. by output unit, system chart is shown in Fig. 1, Fig. 2 is shown in by pick-up unit sketch, Fig. 3 is shown in by cylinder schematic diagram, and Fig. 4 is shown in by execution machine composition, and A-A sectional view is shown in Fig. 5.The existing optoelectronic switch of coupling mutually selected by the input equipment of PLC, magnetic is opened the light, travel switch or proximity switch etc.; Export executive component and select motor for speed reducer.
The course of work now with regard to this device is described as follows: referring to Fig. 2 and Fig. 4, when cylinder is altered, intermediate detection device detects this cylinder alters signal and sends it to PLC, PLC starts to control reductor according to signal and rotates, drive worm and wormwheel to start to rotate, viewed from this side of connection box for motor, worm screw turns clockwise, and the orienting sleeve 4 in left side is retracted backward, the orienting sleeve 4 on right side stretches out forward, makes cylinder be returned to normal position by the friction force of axis direction to cylindrical shell changing support roller; When altering under cylinder, reductor turns on the contrary, and the orienting sleeve in left side stretches out forward, and the orienting sleeve on right side is retracted backward, contrary with situation when above altering.The process flow diagram that motor for speed reducer controls is shown in Fig. 6, when cylinder departs from normal position, motor for speed reducer starts to start, and forward stops after running 6 seconds, keeps 10 seconds, wait for pick-up unit feedback signal, when detecting that cylinder still departs from normal position, repeat above process, until when detecting that cylinder returns to normal position, motor for speed reducer reverse starting stops after running 2 seconds, terminates correction process.The rotation direction of motor is determined by middle two detecting elements, and sequential control is all fixing concerning upper and lower play.For the purpose of safety, arrange two extreme position detecting elements in outside, cylinder play sends alerting signal to PLC during this position, and cuts off the power supply of drum driven motor for speed reducer, in order to avoid damage equipment.
