Description
Technical field
The invention belongs to logistlcs technology field, be related specifically to a kind of to bag platform irregularly shaped object on halved belt sorter
Measuring method.
Background technology
At postal and logistic industry, halved belt sorter is often used, and along with the sorting ability of halved belt sorter
Lifting, automatically supporting the most slowly the popularizing of upper bag piece supplying equipment.Along with customer requirement improves constantly, upper bag platform detection dress
Putting and also constantly update, the most most basic device utilizes Measuring light screen or measures photoelectricity group measurement object on upper bag platform
Position and approximate dimensions.Owing to its calculation is relatively easy so that wherein irregular object is transported on dolly belt feeder
Time may stretch out the outer rim of dolly, such object is easily disturbed when high-speed cruising, occurs reporting to the police or blanking is inaccurate,
Cause Packet Error Rate higher.
Summary of the invention
It is desirable to provide it is a kind of to the measuring method of bag platform irregularly shaped object on halved belt sorter, to upper bag platform not
Size and the position of regular object measure, and make irregular object entirely fall within dolly outer rim, to improve the accurate of upper bag
Degree, reduces Packet Error Rate, reduces labor intensity of operating staff simultaneously.
To achieve these goals, the technical scheme is that
To the measuring method of bag platform irregularly shaped object on halved belt sorter, upper bag platform includes Measuring light screen, light curtain controller, with
And PLC technology PLC, connect Measuring light screen and light curtain controller by cable.PLC technology PLC leads to light curtain controller
Cross the RS485 mode of connection to be attached, use free-port communication agreement to carry out communication.Concrete steps include:
Step 1: first optical axis distance belt edge of Measuring light screen is an optical axis distance.Object is by Bao Taipi upper during light curtain
Speed is kept to be the constant speed of V with machine, simultaneously by detecting the range ability S of measurement device belt feeder.
Step 2: the position relationship arranged according to step 1, with direction, belt edge as Y-axis, measures curtain direction for X-axis foundation
Two-dimensional coordinate system.By object according to one rectangle of belt direction projection or class rectangle so that rectangle or the center of class rectangle and little
Railway carriage band center superposition, at this time has only to rectangle or class rectangular dimension less than dolly belt rectangular dimension, then on object meets
Bag requirement.
Step 3: set up two linear parallel equation group with the slope of dolly length and width place straight line in two-dimensional coordinate system, with
Point on object contour line is point of contact, compares the intersection point of tangent line and Y-axis, takes out in parallel system of equations maximum intersection point equation and
Little intersection point equation, is intersected the class rectangle asked for needed for the rectangle formed is by these four linear equations.Calculate the limit of class rectangle
Length and middle point coordinates in a coordinate system, it is achieved the measurement of two parameters of irregular object size and position arbitrarily put,
Reliable parameter is provided for the operation equation of bag on upper bag platform.
The measuring method of the present invention is to combine Modeling Calculation out according to actual object and dolly relation by parsing,
Comparing traditional computational methods, the inventive method has reliable Mathematics Proof in theory.In actual test, as long as belt runs
Stable, displacement measurement is accurate, and Measuring light screen is measured precision and met requirement, the model of foundation with actual very close to.
So solve the package operation personnel randomness to upper bag putting position and the arbitrariness problem of container dimensions, substantially increase
The suitability of upper bag platform, reduces the workload of operator simultaneously, reduces operation labor intensity.
Accompanying drawing explanation
Fig. 1 is bag platform schematic diagram on sorter.
Fig. 2 is computation modeling principle schematic of the present invention.
In figure, 1-upper bag section belt feeder, 2-sync section belt feeder, 3-collaborates section belt feeder, 4-control chamber, and 5-measures light
Curtain, 6-dolly, the irregular object of 7-, the projection on dolly direction of the 8-irregular object.
Detailed description of the invention
Embodiment below in conjunction with the accompanying drawings further illustrates
As it is shown in figure 1, upper bag platform includes bag section belt feeder 1, sync section belt feeder 2, collaborate section belt feeder 3.Upper bag section belt
Installing Measuring light screen 5 between machine 1 and sync section belt feeder 2, light curtain controller and PLC technology PLC are arranged on control chamber 4,
Measuring light screen and light curtain controller is connected by cable.PLC technology PLC is entered by the RS485 mode of connection with light curtain controller
Row connects, and uses free-port communication agreement to carry out communication.Require that first optical axis distance belt edge of Measuring light screen is a light
Wheelbase from.Require that object is the constant speed of V by keeping speed during light curtain during upper bag platform belt feeder, coding disk can be passed through simultaneously
Measure the range ability S of sync section belt feeder.
As in figure 2 it is shown, to the measuring method of bag platform irregularly shaped object on halved belt sorter, comprise the following steps:
Step 1: first optical axis distance belt edge of Measuring light screen installation requirement is an optical axis distance.Converter can be passed through
Bag section belt feeder in driving, servo driver drives sync section belt feeder, regulation converter and servo controller make bag section
Belt feeder and sync section belt feeder keep constant speed V to run, and drive the pulse frequency of servomechanism by gathering sync section skin belt feeder
Measure the range ability S of belt feeder.
Step 2: according to the position relationship of step 1, with direction, belt edge as Y-axis, measuring curtain direction is X-axis, sets up two
Dimension coordinate system.By measuring the detection of grating, irregular object 7 arbitrarily of each moment can be obtained by outside during Measuring light screen
Shape profile point coordinate points in setting up coordinate system.
Step 3: in Fig. 2, sets up two parallel linear system of equations in a coordinate system:With(whereinFor angle between upper Bao Taiyu sorter), system of equations slope is long with dolly 8 respectively
Wide place straight slope is equal.
From the beginning of isoelectric membrane Measuring light screen, just depart from light curtain to object and terminated, two constantly Measuring light screen recorded
