System and method for fix pitch parcel distribution

1. A system for distributing a stream of articles at a fix pitch comprising:

a belt assembly comprising a plurality of belt segments carrying a stream of articles,

a sensor assembly comprising a plurality of sensors,

a control system interfacing with the belt assembly and the sensor assembly,

wherein the sensor assembly provides measurements of initial positions of each article of the stream of articles and transmits the measurements to the control system,

wherein the control system utilizes the measurements to determine deficits of the initial positions to final positions for each article based on a predefined pitch value,

wherein the control system controls a speed of the plurality of belt segments to provide the final positions for each article according to the predefined pitch value, and

wherein the control system, after determining the initial positions of each article, determines a machinability of each article.

2. The system of claim 1 , wherein the control system calculates a deficit of an initial position with respect to a final position of a first article based on the predefined pitch value.

3. The system of claim 2 , wherein the control system calculates and controls the speed of at least one belt segment in order to establish the fix pitch value for the first article.

4. The system of claim 3 , wherein the sensor system measures a length and a trailing gap length of the first article and transmits the length and trailing gap length to the control system.

5. The system of claim 4 , wherein a first belt segment comprises a constant belt speed, wherein a speed of a second belt segment is calculated based on the constant belt speed of the first belt segment, the deficit of the first article and a sum of the trailing gap length and a location of the trailing edge with respect to a center of the first article.

6. The system of claim 1 , wherein the stream of articles comprises parcels or packages.

7. The system of claim 6 , wherein the control system is configured to select one or more belt speed sequences based on the measurements provided by the sensor assembly to control the speed of the plurality of belt segments.

8. The system of claim 1 , wherein the control system comprises a memory storing a look up table, the look up table comprising a plurality of belt speed sequences relating to different initial configurations of streams of articles.

9. A method for distributing a stream of articles at a fix pitch value comprising:

through operation of at least one processor in a control system configured via executable instructions included in at least one memory:

receiving measurements of initial positions of a stream of articles travelling on a first belt segment,

determining deficits in the initial positions with respect to final positions based on a predefined pitch value,

controlling a speed of a second belt segment such that the stream of articles comprises the final positions including the predefined pitch value, and

after determining the initial positions of the stream articles, determining a machinability of each of the stream of articles.

10. The method of claim 9 , further comprising:

calculating a deficit of the initial positions with respect to the final positions for each article utilizing measurements provided by a sensor assembly.

11. The method of claim 10 , wherein the sensor assembly measures the length and trailing gap length of each article and transmits measurements to the control system.

12. The method of claim 10 , further comprising:

calculating the speed of the second belt segment utilizing the length and trailing gap length of each article.

13. The method of claim 12 , wherein calculating the speed of the second belt segment is based on the deficit, a speed of the first belt segment and a sum of a trailing gap length of an article and a location of a trailing edge with respect to a center of the respective article.

14. The method of claim 9 , further comprising:

recognizing a configuration of the initial positions of the stream of articles, selecting a belt speed sequence stored in a look up table, and

controlling the speed of the second belt segment according to a selected belt speed sequence.

15. A non-transitory computer readable medium comprising instructions that when executed by at least one processor perform a method for distributing a stream of articles at a fix pitch value comprising:

receiving measurements of initial positions of a stream of articles travelling on a first belt segment,

determining deficits in the initial positions with respect to final positions based on a predefined pitch value,

controlling a speed of a second belt segment such that the stream of articles comprises the final positions including the predefined pitch value, and

after determining the initial positions of the stream of articles, determining a machinability of each of the stream of articles.
