Transition speed stabilizing method for mover to pass through junction of magnetic levitation belts

Abstract

The invention discloses a transition speed stabilizing method for a rotor to pass through a junction of a magnetic levitation line and a belt line, a speed stabilizing area is additionally arranged between the magnetic levitation line and the belt line, a speed stabilizing device is additionally arranged in the speed stabilizing area, and the speed stabilizing device can realize the purpose of uniformly reducing / increasing the attractive force in the speed stabilizing area; when the mover passes through a magnetic levitation line and a belt line, the attractive force changes uniformly, the load change of a driver in the belt line is relatively gentle, stable operation of the belt line is ensured, meanwhile, a coil and a permanent magnet acting on the mover can be additionally arranged in a stable speed area, the motion state of the mover is correspondingly adjusted, so the rotor is enabled to be more stable when entering and exiting from the belt line.

Description

technical field [0001] The invention relates to the field of conveying devices, in particular to a transitional speed stabilization method. Background technique [0002] The maglev conveyor line is mainly composed of coils, permanent magnet plates, and position detection devices. The current passes through the coil to generate a magnetic field, which generates an interaction force with the permanent magnet plate and then moves, and the position detection device obtains the motion state data such as the position and speed of the motion to the control system for control. [0003] Because the maglev conveyor line has the characteristics of controllable speed and precision, in the actual production process, for areas that require precise processing, it is necessary to use a high-speed and high-precision conveying system such as a maglev module. [0004] At the same time, due to the high purchase cost of the maglev conveyor line, in some road sections that only need to be transp...

Problems solved by technology

There is a cogging force between the permanent magnet plate and the coil of the mover 5, which will cause the permanent magnet plate to have resistance when moving relative to the coil

[0010] Since there is no overlapping area between the buffer module 10 and the belt line 2 (after overlapping, the buffer module 10 loses the ability to buffer the mover 5), so when the mover 5 breaks away from the buffer module 10 and enters the belt line 2, assuming At this time, the mover 5 is located at the junction 6 between the two, and the mover 5 gradually leaves the buffer module 10. When it starts to rub / engage with the belt, the buffer module disconnects the excitation and no longer provides thrust, and the permanent magnet of the mover 5 When the plate is separated from the coil on the cache module, it must overcome the large attraction from the coil (when the mover 5 is inside the cache module 10, the attraction force of the coil to the mover in the forward or backward direction is approximately balanced), It will cause the load of the belt line 2 driver (the output power remains unchanged) to increase instantaneously, which may cause the contact part of the mover 5 and the belt line 2 to slip, and the mover cannot enter the belt smoothly. Reduced belt life

[0011] In another case, the mover 5 is gradually detached from the belt line 2, and when it enters the buffer module 10, the permanent magnet plate on the mover 5 is subjected to the attractive force from the coil, and at the junction 6, it may cause the mover 5 slips on the belt 2 and is quickly attracted to the cache module 10 or even the magnetic levitation line 1, causing failure
