Abstract
The utility model discloses a rubber magnet synchronous belt. A polyurethane layer is adhered onto the outer side of the whole synchronous belt. One or more than one rubber magnet sections are adhered between the polyurethane layer and the outer side of the synchronous belt according to numbers of positions required being detected on the synchronous belt. A magnetic sensor is fixed within a detection range of the magnetic sensor selected by the synchronous belt with a distance no less than 10mm. When one section of synchronous belt adhered with the rubber magnet moves to the position of the magnetic sensor, the magnetic sensor generates trigger signals, and the trigger signals passing by a signal processing circuit are finally sent into a master control system to judge whether or not the synchronous belt reaches the position with the rubber magnet. The rubber magnet synchronous belt can realize detection of one or a plurality of positions of the synchronous belt during moving within a long and narrow space, is reliable and convenient in detection, and further increases control stability and reliability of a transmission system of the synchronous belt.
Description
Technical field
The utility model relates to a kind of synchronous band, especially relates to a kind of rubber magnet and is with synchronously.
Background technique
Band transmission synchronously is widely used in the various types of mechanical transmission of every profession and trade.In band transmission synchronously, often need to limit synchronous band and move reciprocatingly within the specific limits, just stop when perhaps needing synchronous band to move to specified position at every turn.At this moment just need be at the initial sum final position of taking to reciprocating motion synchronously or the station acquisition testing signal that needs band synchronously to stop, according to this signal, control band synchronously stops or commutating at specified position.In order to obtain this signal, traditional method can adorned the detection encoder in the band driving mechanism synchronously, write down position of synchronous belt information so real-time and accurately, and the start code device value of synchronous band is set and stops encoder values or the encoder values of specified position, if but this kind method is higher in speed, under the bigger situation of load change, band is through relaxing behind the long-play synchronously, wearing and tearing, generation is skidded, the position of the position of encoder record and band actual motion synchronously just has deviation like this, and the motion of band synchronously will exceed initial position and final position and maybe need the position that stops.
In order to obtain synchronously testing signal with specified position, specified location installation and measuring sensor that usually can also be on band moving direction synchronously.But this method for detecting position, the general assisting agency that all needs to utilize asynchronous band itself, remove the detection trigger element, assisting agency and installation and measuring element itself that all detection trigger elements are installed all need certain space just can finish, in a lot of synchronization belt transmission systems, be difficult to satisfy the requirement of this large space.
Summary of the invention
The purpose of this utility model is to provide a kind of rubber magnet to be with synchronously, can realize one and a plurality of position probing when band moves synchronously in long and narrow space, detect reliable, convenient, do not need extra installing space, compact structure further improves the stability and the reliability of synchronization belt transmission system control.
The technical solution adopted in the utility model is:
One, a kind of rubber magnet is with synchronously:
The utility model is to be with outside bonding one deck layer of polyurethane synchronously at whole piece, the rubber magnet of bonding more than one section or one section between the layer of polyurethane and the synchronous band outside.
Two, a kind of magnetic non-contact detection method of position of synchronous belt:
1) in outside bonding one deck layer of polyurethane of being with synchronously, the layer of polyurethane envelope is in the whole synchronous band outside;
2) according to the quantity of being with the detected position of needs synchronously, the rubber magnet of bonding more than one section or one section between the layer of polyurethane and the synchronous band outside;
3) magnetic sensor is fixed in the detection range with selected magnetic sensor synchronously, and distance can not be less than 10mm;
4) when one section that is bonded with rubber magnet band moves to the position of magnetic sensor synchronously, magnetic sensor can produce trigger signal, trigger signal is after signal processing circuit, finally send into master control system, master control system is judged synchronous band according to the signal of gathering and whether has been arrived the position that rubber magnet is housed.
The beneficial effect that has of the present utility model is:
The utility model can realize being with synchronously and a plurality of position probing when moving in long and narrow space, detection is reliable, convenient, further improves stability and reliability that synchronization belt transmission system is controlled.
Description of drawings
Fig. 1 is the rubber magnet structure and the scheme of installation of band synchronously.
Fig. 2 is the rubber magnet structure partial enlarged diagram of band synchronously.
Among the figure: 1, magnetic sensor, 2, one of rubber magnet mounting point, 3, the rubber magnet mounting point two, 4, signal processing circuit, 5, master control system, 6, layer of polyurethane, 7, rubber magnet, 8, band synchronously.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figure 1 and Figure 2, the utility model is to be with 8 outsides bondings one deck layer of polyurethane 6 synchronously at whole piece, in layer of polyurethane 6 with the rubber magnet 7 that bonds between synchronously with 8 outsides more than a section or a section.
2 is one of rubber magnet mounting points among Fig. 1, and two place's rubber magnet have also promptly been installed in two of 3 rubber magnet mounting points.Here be example so that two place's rubber magnet to be installed, the utility model mode of execution is described, but the utility model does not limit the number of positions that rubber magnet is installed.
As Fig. 2 synchronously with 8 outside bonding one deck layer of polyurethane 6, make layer of polyurethane 6 envelopes outside whole synchronous band.Is to prepare for further installation rubber magnet 7 below giving synchronously with outside envelope one deck layer of polyurethane 6 of 8.According to the quantity of the detected position of synchronous band needs, two detection positions are arranged here, so one of rubber magnet mounting point locate with the rubber magnet mounting point two respectively the bonding on rubber magnet 7.The adhesive method of rubber magnet 7 is: get one section rubber magnet 7, need the position of synchronous belt of sticking rubber magnetic at each, this section rubber magnet 7 is bonded between the layer of polyurethane and the synchronous band outside.Bonding time, make rubber magnet 7 inner and outer surface and layer of polyurethane, the surface of contact of belt is fully bonding synchronously, do not interspace.Synchronously with 8 the skin layer of polyurethane 6 from level to level that bonds, can make rubber magnet 7 synchronously with on fixing more firm, make rubber magnetic energy follow synchronous band reliably and move together, do not produce and peel off, drop.
The output signal line of magnetic sensor 1 is inserted signal processing circuit 4, and the signal that signal processing circuit 4 is come out enters master control system 5.Signal processing circuit 4 mainly is made up of sample circuit and eliminator.Sample circuit can simply keep chip, A/D chip to constitute with sampling, and eliminator can be used the LC low-pass filter of 50KHz.Master control system can be industrial PLC control system, also can be embedded control system.
When one section that is bonded with rubber magnet band moved to the position that rubber magnet is housed synchronously, magnetic sensor can produce trigger signal.This signal is the entering signal processing circuit at first, signal processing circuit to signal sample, filtering, obtain stable, operational testing signal, and signal be input to master control system.Master control system is judged synchronous band according to the signal of signal processing circuit and whether has been arrived the position that rubber magnet is housed.
