The specific embodiment
Feedway shown in Fig. 1 to 3 comprises a track-type facilities 1 that is made of many guide rails 2 that are provided with in succession.Each guide rail 2 has the matrix 3 that a usefulness foundry engieering is made, two pilot bars 4, a magneto-strictive sensor 5 and a plurality of coil 8 with sounding rod 6 and measuring head 7 are set therein, and these coils have the laminated core as the A end of linear drive apparatus.The vehicle side of guide rail 2 is covered by a stainless steel sheet 9.
The vehicle 11 that travels on track-type facilities comprises a plurality of mutual hinged vehicles 11a, 11b, and wherein each part has two wheels 12.Four sign magnet 13 altogether are set on this external each vehicle, and are two of each sides.Before each sign magnet 13 and/or on vehicle, fix each guidance magnets 14 afterwards.On this external vehicle following each drive magnet 15 is set therebetween, itself and coil 8 combineds action are so that along track-type facilities powered vehicle 11.
Each guidance magnets 14 is vertically set on the top of each pilot bar 4.The latter comprises that respectively one has towards the U-shaped section bar of the side of running route orientation, and it constitutes along the vertical axis extension of track-type facilities and by magnetizable material.So-called " magnetizable " should be understood that to have the material than the ferromagnetic or paramagnetic of 1 big many permeability here, and it applies a strong attractive force to guidance magnets 14.
As conspicuous by Fig. 5, guidance magnets 14 is polarized on the dual-side that makes different magnetic poles be positioned at corresponding pilot bar 4, thereby it is closed circuit to produce a magnetic by the U-shaped section bar.
Guidance magnets 14 is sized to make and produces enough strong mutual action between they and each pilot bar 4, so that vehicle also can remain on the track-type facilities 1 in bend.If guidance magnets is sized to enough strong, then also can vehicle 11 be set suspension type.
Driving realizes via the electron steering of coil 8 that by a control setup 17 this control setup 17 schematically is shown among Fig. 2.Control setup 17 constitutes a regulating circuit, and its adjusting parameter is that its controlled parameter is measured vehicle location by the electric current of each phase of coil 8.In other words, therefore the electric current by coil 8 is chosen to make vehicle to drive towards by control setup or keeps a preposition (it can be relevant with the time), and wherein Shi Ji position is definite by magneto-strictive sensor 5.
As mentioned above, each magneto-strictive sensor 5 comprises a sounding rod 6, and it extends along the guide rail longitudinal direction.Preferred sounding rod 6 is arranged in the U-shaped section bar of pilot bar 4, as shown in Fig. 3 and 4, and in the side of coil 8 outward flange along track-type facilities 1 extends, as shown in Figure 2.
Sounding rod 6 is made of magneto-strictive material.It is flow through by a current impulse with regular time intervals, and current impulse is with the magnetic field interaction that indicates magnet 13 and produce a ultrasonic pulse.This ultrasonic pulse is being detected along the rodmeter extension and in corresponding measuring head 7.Can infer the position of sign magnet 13 by the time delay between current impulse and the ultrasonic pulse that detects.
The magneto-strictive sensor of describing pattern here is for example by MTS SensorTechnologie GmbH ﹠amp; Co.KG (Germany) company provides with brand name Temposonics .
6 of preferred each sounding rods extend along a guide rail.But also can imagine the sounding rod 6 that employing is extended along some guide rails.Also can imagine the combination of the sounding rod of different length.
Along guide rail longitudinal direction each sounding rod in succession do not have overlap joint continuously (promptly not transverse to the laterally offset of guide rail longitudinal direction) be provided with and constitute one and measure route.The permission that is provided with of the nothing overlap joint of each sounding rod 6 is incorporated into them in each guide rail 2 fully.But they cause, and have some zones 20 between each guide rail 2, can not detect a sign magnet 13 in these zones.But owing on each vehicle 11, be provided with two sign magnet of arranging in succession 13 for each sounding rod 6, and has spacing to each other greater than zone 20 length, if vehicle is in the zone between two guide rails 2, then still can detect a vehicle by at least one sounding rod 6 by measuring and controlling 17.
