Background technology
The capacity rating of sorting unit is determined by the productive output and the quality (dual extraction yield and damage rate) of its separation equipment in input area fatefully.
At this, by identification separated transport thing (to antemarginal detection) and the acceleration next one transports thing and comes limited throughput.Separated transport thing and the follow-up velocity jump that transports between the thing high more, quicken that next to transport the time that thing continues just long more.The gap of transporting between the thing is therefore big more.
So far, separation is to realize by transportation means, mechanical support element (Rueckhalteelement) and by the thing that transports in the grating identification separated region.If it is separated to transport thing, then these sensors are merely able to discern front edge and the lagging dege that transports thing, and these sensors can utilize measurement signal to influence the control (DE 198 01 309 C1, DE 34 24 397 A1) of separation.
Known a kind of method and apparatus that is used for coming separating flat consignments from US 5 429 347 A by means of single accelerating stage.This accelerating stage has in a side transporting the draw-out device of deposits yields influence.Be attached to the speed of transporting thing on this draw-out device by the sensor measurement, this sensor is constructed to drive the roller of tachogenerator and is disposed in the draw-out device side.By control setup, from measured velocity variations process, detect and transport the front edge of thing, and correspondingly control the driving of draw-out device.
Except single-stage is separated, also known multistage-separation (MSS), in this multistage-separation (MSS), the nominal extraction speed of the draw-out device in the follow-up accelerating stage is higher than the nominal of the draw-out device in the preposition accelerating stage and extracts speed (DE102 12 024 A1).
Summary of the invention
The present invention based on task be, a kind of method and apparatus that is used for separating flat consignments is proposed, utilize this method and apparatus to hold back the overlapping thing that transports better.
According to the present invention, the feature by claim 1 and 7 solves above-mentioned task.
In a plurality of accelerating stages in succession, the nominal extraction speed of the draw-out device in each accelerating stage is higher than the nominal of the draw-out device of corresponding preposition accelerating stage on transporting direction and extracts speed.
In the input area of each accelerating stage, be attached to the speed of transporting thing on described one or more draw-out device by means of the sensor T1 measurement that is disposed in the draw-out device side.
As long as in the input area of corresponding accelerating stage, only depart from determined small value by means of being disposed in sensor T1 on draw-out device side datum speed measured, that be attached to the draw-out device of the speed of transporting thing on the draw-out device and this accelerating stage, when that is to say that as long as transporting thing is almost fricton-tightly received by this accelerating stage, just will reduce in the speed of the draw-out device of the accelerating stage before being placed in this accelerating stage on the transporting direction.Hold back the overlapping thing that transports thus.
Favourable improvement project of the present invention is elaborated in the dependent claims.
Sensor T1 advantageously is disposed between the described accelerating stage.
In order also to determine the extra speed of transporting thing that drag away together, overlapping in extraction process, advantageously, the sensor T2 that is disposed in a side that deviates from draw-out device in addition in the zone by means of corresponding follow-up accelerating stage on transporting direction measures the speed of transporting thing that can scan on this side.
In order to determine draw-out device because when wear phenomenon must be replaced, advantageously, the speed of draw-out device and the speed of transporting thing by its driving are compared mutually,, and when deviation is higher than determined limit, produce maintenance signal so that determine sliding condition.
Advantageously, the speed with preposition accelerating stage is reduced to 0.
When additionally when transporting the speed of thing by means of sensor T2 measurement in the zone of each follow-up accelerating stage on transporting direction, this is particularly advantageous, this sensor T2 is disposed on the side that deviates from draw-out device, and, just the speed of the draw-out device of corresponding preposition accelerating stage is brought up to its datum speed once more as long as so only depart from determined small value with the datum speed of this follow-up accelerating stage after the speed of the draw-out device of the speed of measuring of transporting thing in reducing corresponding preposition accelerating stage.As long as be registered as the measured velocity jump from v to v by means of the detected thing front edge that transports of the sensor T2 of follow-up accelerating stage, the rapid change of the draw-out device of just will be corresponding preposition accelerating stage is to being worth 0.As long as from speed value of being reduced to 0 of v almost, just the draw-out device with corresponding preposition accelerating stage accelerates to nominal extraction speed by the measured thing speed of transporting of the sensor T1 between two adjacent accelerating stages.Distance between the initial point of corresponding accelerating stage and the sensor T2 that is distributed and therefore the follow-up breakpoint that transports the front edge of thing so select according to the difference between the datum speed of corresponding accelerating stage and preposition accelerating stage, consequently two adjacent things that transport of corresponding accelerating stage afterbody have definite distance each other.By this process, although it is very big to transport the size differences of thing, the gap of transporting between the thing of being separated is very little.
Description of drawings
The present invention will be described with embodiment by accompanying drawing below.
At this, Fig. 1 illustrates the schematic side elevation of two accelerating stages of the separation equipment with two speed sensors.
The specific embodiment
Come by means of first accelerating stage 1 according to Fig. 1 from unshowned transport to extract the thing heap transported thing at 3,4 o'clock, not only extracted the top of thing heap that transport that is attached on the draw-out device (for example extraction band of the annular that supports by negative pressure chamber) and transported thing 3, but also drag away together two other transport thing 4.This first order can be the level that is used for carrying out pre-separation also, transports thing 3,4 and leaves this level overlappingly.At least the top thing 3 that transports is with datum speed vA1 accelerating stage 2 transportations rearwards.This is top to transport thing 3 one and is detected by draw-out device at that, just continues transportation with higher speed v A2.Placement sensor T1 5 between two accelerating stages 1,2, this sensor T1 5 measures the speed of transporting thing that is attached on this draw-out device.Here by means of realizing this measurement at the roller that transports on the thing surface running and drive tachogenerator.To send the equipment of the driving that is used to control accelerating stage corresponding to the output signal of the tachogenerator of rotating speed to as measurement signal.If the gap between the accelerating stage 1,2 is very little or do not exist, then this sensor T1 5 can be arranged in the input area of corresponding follow-up accelerating stage 2 and extracts between the band.Leave preposition accelerating stage 1 if transport thing 3 accordingly, then by sensor T1 5 its speed of monitoring.If the speed of the draw-out device of follow-up accelerating stage 2 and transport difference between the speed of thing 3 less than the little limit that is limited can think that then the draw-out device of follow-up accelerating stage 2 is almost fricton-tight to the reception of transporting thing 3.From this constantly, the speed of the draw-out device of preposition accelerating stage 1 reduces (from maxim value of dropping to 0), so that this draw-out device plays the effect of supporting member, and stops or hinder follow-up transportation of transporting thing at least.In the zone of follow-up accelerating stage 2, another sensor T2 6 is disposed on the side that deviates from draw-out device in transmission direction, and this sensor T2 6 measures the speed of transporting thing 3,4 that can scan on this side.Transporting thing 3 almost with speed v A2Leave during the transition phase between two accelerating stages 1,2, monitoring is by the measured speed v of sensor T2 6 T2If v A2And v T2Between velocity contrast greater than the little limit that is limited, can think that then the follow-up front edge that transports thing 4 is not also on sensor T2 6, and the draw-out device of preposition accelerating stage 1 accelerates to its datum speed from the speed that is reduced.Thus, the follow-up thing that transports transports (vortransportieren) with datum speed in advance to sensor T2 6.If sensor T2 6 by its write down preposition accelerating stage 1 draw-out device to datum speed v A1Velocity jump identify the follow-up front edge that transports thing 4, then stop the draw-out device of preposition accelerating stage 1, and make it play the effect of supporting member once more.
