Really.For the bar code superscribed after code reader reading code, sorting control system can distribute the corresponding blanking of the article every slogan to delivery
Trolley.When carrier loader run to accordingly every mouth when, can rapid rotating belt, give package one prodigious acceleration, under realization
Packet.If package, if to the rear, may shift to an earlier date down toward previous every mouth not in centre.If package is to the front, it is likely that down toward rear
One every mouth.Various situations can occur because the position of package is uncertain, divide so as to cause package is wrong.Some are compared with heavy articles
It more likely impinges upon every on mouth baffle, article is caused to damage.So the central point that can package go up packet to trolley is especially heavy
It wants.If each package is accurately located at trolley centre, package will perfectly be carried out blanking by matched acceleration,
Accurately and without shock.To improve the sorting accuracy rate of halved belt sorter.
By prolonged field adjustable with test, the segmented adjusting method, can significantly improve package up to
The efficiency of carrier loader center, accuracy rate is up to 99%, and in the case of wrapping up itself specification, accuracy rate is reachable
99.9%.This has great meaning for the whole sorting rate, discrimination, the sorting accuracy rate that improve entire halved belt parcel sorting machine
Justice.

Specific implementation mode
With reference to specific drawings and examples, the invention will be further described.
Halved belt parcel sorting machine is equipped with cart transport line, and 600mm is arranged in cart transport each carrier loader at equal intervals
On line；The upper packet action wrapped up for carrier loader of the sides Bao Taicong on cart transport line；The operation speed of carrier loader
Degree is 2m/s；It is equipped with light curtain for packet platform；
The process of upper packet as shown in Figure 1,
Package enters for packet platform first, drives package movement for packet platform, wraps up after light curtain, connect for the controller of packet platform
By the synchronization photosignal of carrier loader, at the same receive carrier loader number, carrier loader whether have package and carrier loader energy
The information such as no normal upper packet；If carrier loader normally upper can wrap, success is synchronized.It calculates and synchronizes successfully the moment synchronization time
With package by the time difference between the light curtain moment.
Adjusting control for package includes：Initial velocity control section, Accelerating running section, travel at the uniform speed section；Above three segment value obtains
It is time control section；
Package includes the following steps for packet platform segmented adjusting method：
In initial velocity control section, measures packages length and carried out respectively according to packages length：The sectional-regulated step of small packet, in
Wrap up sectional-regulated step, reduction of speed regulating step；
In this step, when being wrapped in by light curtain, light curtain can sense passed through packages length；
(1) as packages length L ＜ L1, it is sectional-regulated to carry out small packet；L1 is the first length threshold, is in this example
300mm；
As shown in Fig. 2, in the sectional-regulated step of small packet, the speed V of initial velocity control section0For steady state value, V in this example0=
1m/s, Accelerating running section include the first accelerating sections, intermediate at the uniform velocity section and the second accelerating sections, the acceleration a1=of the first accelerating sections
2.7m/s2, speed V is accelerated in the first accelerating sections package1, i.e., the speed that intermediate at the uniform velocity section is kept, V in this example1=1.5m/
S, the acceleration a2=2.7m/s of the second accelerating sections2, then V is accelerated in the second accelerating sections package2, that is, the section that travels at the uniform speed guarantor
The speed held；V in this example2=2.3m/s；
In the sectional-regulated step of small packet, using relatively small acceleration, it will not be spent because of acceleration ensureing to wrap up
While big and generation is rolled, consumption as possible waits for the time that carrier loader arrives, the accurate upper packet of realization；The section that travels at the uniform speed is realized
Package is delivered on carrier loader, similarly hereinafter；
(2) when packages length L meets L1≤L ＜ L2, sectional-regulated step is wrapped up in progress, L2 is the second length threshold
It is worth, is 400mm in this example；
As shown in figure 3, in the middle sectional-regulated step of package, the speed V of initial velocity control section0For steady state value, V in this example0=
1m/s, Accelerating running section include the first accelerating sections, intermediate at the uniform velocity section and the second accelerating sections, are accelerated in the first accelerating sections package
Speed V1, i.e., the speed that intermediate at the uniform velocity section is kept, V in this example1Then=1.9m/s is accelerated to V in the second accelerating sections package2,
The speed that the section that travels at the uniform speed is kept；V in this example2=2.3m/s；
The middle sectional-regulated step of package, the acceleration a1 of the first accelerating sections and the acceleration a2 of the second accelerating sections are variable
, in 2.7m/s2~5m/s2Between, when encountering the package in this length range, regulative mode be it is very flexible and changeable,
This is conducive to more smoothly carry out upper packet control in correct time；
(3) when packages length L meets L >=L2, reduction of speed regulating step is carried out；
Reduction of speed regulating step is divided into three kinds of situations：
As shown in Table 1：
| Packages length L | It is applicable in regulative mode |
| 400mm≤L ＜ 500mm | Synchronous second vehicle regulating stage by stage |
| 500mm≤L ＜ 600mm | Stopping and again upper packet regulative mode |
| L≥600mm | Stopping, alarm, manual sorting |
Table one
As L2≤L ＜ L3, the second vehicle regulating stage by stage is synchronized, L3 is third length threshold, is in this example
500mm；
In synchronous second vehicle regulating stage by stage, package can miss a parcel loading machine meeting, to package in initial velocity control section
Initial velocity reduction of speed to less than initial velocity a speed；So that package waits for second of parcel loading machine meeting；Ensure package
Back to back parcel loading machine meeting will not be missed, to improve efficiency；Then carry out that Accelerating running section, travel at the uniform speed section again；
As L3≤L ＜ L4, stopped simultaneously upper packet regulative mode again, L4 is the 4th length threshold, is in this example
600mm；
Stop and go up in packet regulative mode again, package can miss secondary parcel loading machine meeting, in initial velocity control section to wrap up into
Row stops operation, that is, the initial velocity wrapped up is reduced to zero, then carries out that Accelerating running section, travel at the uniform speed section again；Simultaneously using stopping
It is too long really that upper packet regulative mode again, which is due to wrapping up, but is less than the delivery maximum length of carrier loader again, it is necessary to first
It is stopped operation, is then further accelerated, to realize last upper packet；
As L >=L4, stops package and run and alarm；Warning light can be light, reminds operating personnel to carry out artificial
Sorting.Such case is because packages length has been more than the delivery maximum length of carrier loader.
