A kind of square crossing band sorter
Technical field
The utility model belongs to logistics Sorting Technique field, and in particular to a kind of square crossing band sorter.
Background technique
With economic development, more stringent requirements are proposed for dispatching speed and accuracy for modern logistics, thus by passing
The logistics operation mode of system is no longer satisfied the demand of industry, and then forces the development of logistic industry equipment, especially pair
More stringent requirements are proposed for sorting device.
Common sorter domestic at present has a traffic circle band sorter, square crossing band sorter, sliding block sorter,
Tiltedly wheel sorter and swing arm sorter.But above equipment has the limitation of itself, and traffic circle band sorter is first to field
Ground requirement is very high, and at least to need 800 square meter places for the monolayer device of 200 bins, and utilization of area rate is extremely low, only
20% or so.Secondly, installation and debugging period of the traffic circle with sorter is long, for 200 bin monolayer devices, at least need
600 working hours are put into, last halved belt sorter input-output ratio is not high, handles for 300,000 tickets with day, and investment needs
Ten thousand yuan of 400-500, if day output is double if need 3 times or bigger cost input.
Existing square crossing is with the spacing that sorter is using the trolley of 600mm pitch as carrier, and between two trolleies
It is larger, this requires having to package to be put among trolley, to abnormal bin can only be removed if between two trolleies on.
Also, existing square crossing needs a parcel loading machine structure as traffic circle with sorter with sorter to guarantee upper packet
Accuracy, simultaneously as the pitch of trolley is bigger dynamically to adjust trolley number according to the size of package, such as actually
Package dimensions only have 300 millimeters, similarly to occupy a trolley, so the utilization rate of loop wire is not high, and then limit vertical
Halved belt sorts engine efficiency and input-output ratio.Simultaneously as the pitch problem of trolley causes the turning radius of square crossing band most
Small is 0.7 meter, and then a possibility that limit Multilevel method.The traffic circle that compares is not also excellent with cost for sorter
Gesture.
Sliding block sorter tiltedly takes turns sorter and swing arm sorter relative to traffic circle band sorter and square crossing band
Treatment effeciency is lower for sorter, while having rigors to the form of package.
Analysis based on Industry nowadays restricts the fast-developing cause of sorter and is known as at 3 points, and first: place limits
System;Second: the installation and debugging period is long;Third: input-output ratio is not high.Based on the considerations of above 3 points, need to design it is a can
With Fast Installation debugging and the sorting device extremely low while that there is high investment output ratio to site requirements.

Machine 5 and all motorized rollers 12 are connected with controller.Controller uses PLC.
Working principle of the square crossing with sorter is specific as follows:
Step 1: first imports the importing motor 22 of motor 20, second and the third importing rotation of motor 24, so that first imports
Conveying speed with 19 is less than the conveying speed of the second lead-in zone 21, and the conveying speed of the second lead-in zone 21 is equal to third importing
With 23 conveying speed.Later, package is successively put into the first lead-in zone.It is wrapped in from the first lead-in zone 19 and enters the second importing
With when be opened distance greater than 10cm.Each the package of the first lead-in zone 19 is put according to Step 2: three and four are grasped
Make.
Step 2: code reader reads i-th and superscribes bar code information and lead to when lower section of i-th of package Jing Guo code reader
It crosses Internet Protocol (ICP/IP protocol) and is transferred to controller.
The bar code information received is transferred to management information system by controller.Management information system carries out data retrieval,
Obtain the number c of the corresponding lower packet bin of i-th of packagei, and will number ciTransmission is given in controller.
Step 3: recording i-th of the first point wrapped up of transport when laser sensor 18 detects i-th of package
Pick trolley number ai.Number is aiSorting trolley be located at conveying driven shaft 9 sprocket wheel at, and with conveying driven shaft 9 sprocket wheel most
The circular arc distance of high point is equal to f.F=θ × r, wherein θ is that number is aiSorting trolley and convey driven shaft 9 sprocket wheel most
For high point to convey 9 axle center of driven shaft as the angular distance in the center of circle, r is sprocket radius.S-0.85E < f < s, wherein s is laser sensing
Distance of the central axis of device 18 to the sprocket wheel highest point of conveying driven shaft 9.(so that it is a that i-th of package, which occupies number,iPoint
Pick 15% or more of trolley).
When laser sensor 18 from detect i-th of package be changed into can't detect i-th of package when, record i-th
Package passes through the time t of laser sensori.The length l of i-th of packagei=vti, wherein v is the conveying speed of third lead-in zone
Degree.Calculating accounts for vehicle characteristic bi=(li+s-f)/5P.If biFractional part less than 0.15, then wrap up the sorting trolley number of occupancy
Measure bi' it is equal to biIt is rounded resulting value downwards.If biFractional part be greater than or equal to 0.15, then wrap up the sorting trolley number of occupancy
Measure bi' it is equal to biRound up resulting value.The sorting trolley group of i-th of package of transport is by number aiSorting trolley and number ai
Sorting trolley rear (bi' -1) sorting trolley composition.
Step 4: it is c that all sorting trolleies of i-th of package of transport, which are transported to corresponding number,iLower packet bin at when,
Number aiSorting trolley and number aiSorting trolley rear (bi' -1) the small interior motorized roller 12 of sorting rotates synchronously,
So that it is c that i-th of package, which enters number,iLower packet bin.
