A plurality of light curtain electric object sensors are arranged on the machine frame 1, one light curtain electric object sensor is arranged at each group of the double-drive belt units, and the light curtain electric object sensors are arranged on the front sides of the double-drive belt units. The light curtain electric object measuring sensor extends from one side to the other side of the dual-drive belt unit and is used for detecting the entering of the package. The number of the optical curtain electrical object sensors is the same as that of the dual-drive belt units, namely four optical curtain electrical object sensors, namely a first optical curtain electrical object sensor 5, a second optical curtain electrical object sensor 6, a third optical curtain electrical object sensor 7 and a fourth optical curtain electrical object sensor 8.

When no barrier exists between the infrared transmitting tube and the infrared receiving tube on the same straight line, the optical signal sent by the infrared transmitting tube can smoothly reach the infrared receiving tube, namely, a complete light column is formed between the infrared transmitting tube and the infrared receiving tube. After the infrared receiving tube receives the optical signal, the corresponding internal circuit outputs low level, and under the condition of an obstacle, the optical signal sent by the infrared transmitting tube can not smoothly reach the infrared receiving tube, namely, the light column between the infrared transmitting tube and the infrared receiving tube is blocked, at this moment, the infrared receiving tube can not receive the optical signal, and the corresponding internal circuit outputs high level. When no package passes through the optical curtain electric object sensor, the optical signals emitted by all the infrared emission tubes can smoothly reach the corresponding infrared receiving tubes on the other side, so that all the internal circuits output low levels. Thus, the presence or absence of the package can be detected by analyzing the state of the internal circuit.

In this embodiment, each belt 16 of each set of dual-drive belt units corresponds to multiple sets of infrared transmitting tubes and infrared receiving tubes, that is, each belt 16 corresponds to multiple light beams. When the light column corresponding to the belt 16 is blocked, it indicates that a package is about to enter the belt 16.

The working process of the present invention is further explained as follows:

1. the package is conveyed to a first light curtain electric object measuring sensor 5 by the buffer belt conveyor 2, and the first light curtain electric object measuring sensor 5 detects a light column blocked by the package.

2. Judgment of single or multiple packages

When the adjacent continuous light beams are blocked, the light beams can be single-packed pieces or multi-packed pieces, and the single-packed pieces are larger in size.

When a discontinuous column of light is blocked, it must not be a single package. That is to say the light beam interval of the first light curtain electrical object sensor 5 is blocked.

3. When adjacent continuous light columns are blocked

1) If the light beam to be blocked corresponds to the same belt 16

Starting the belt 16 to run quickly to convey a packed piece;

secondly, when the belt 16 does not convey the previous package for a preset distance and other packages enter and are detected by the first light curtain electric object detecting sensor 5, the buffer belt conveyor 2 is controlled to stop running, the next package is stopped to be conveyed, the buffer belt conveyor 2 is controlled to run after the previous package is conveyed for a preset distance, and meanwhile the corresponding belt 16 is controlled. The preset distance is the proper distance between the front and the rear packages, so that the success rate of automatic code scanning is improved, the distance is shortened as far as possible while the requirement of automatic code scanning is met, and the conveying efficiency is improved.

2) If the light beam to be interrupted corresponds to a plurality of belts 16

Description of the drawings if the light pillar being blocked corresponds to two belts 16

a) The belt 16 corresponding to the large number of blocked light columns is started to run fast, and the belt 16 corresponding to the adjacent blocked light columns is started to run slow. If a plurality of parallel packages exist, the packages can be dislocated at a high speed and a low speed, and then the packages enter the next group of dual-drive belt units for next separation; if the single package is a single package with a larger size, the package is described to cross two adjacent belts 16, at this time, the package will gradually move to the belt 16 at one end due to the different driving speeds at the two ends of the package, and if the moving stroke of the first dual-drive belt unit 20 cannot drive the package to one belt 16, the package will continue to be driven to approach the belt 16 at one end similarly while passing through the second dual-drive belt unit 21, the third dual-drive belt unit 22 and the fourth dual-drive belt unit 23.

b) If one of the belts 16 is restored to the blocked light beam and the other belt 16 is still blocked without restoration to the blocked light beam, the belt 16 corresponding to the still blocked light beam is stopped and the buffer belt conveyor 2 is stopped.

c) After the pack being transferred has been fed a predetermined distance, the belt 16 which has just stopped and the buffer conveyor 2 are started.

d) When the package is not conveyed to a preset distance, the first light curtain electric object detecting sensor 5 detects the arrival of the package, the buffering belt conveyor 2 is stopped, and after the package is conveyed to a certain distance, the buffering belt conveyor 2 and the belt 16 corresponding to the light beam are started.

3) If the light beam to be blocked corresponds to three or more belts 16

a) Randomly choose to start the middle one of the belts 16 running fast while starting the adjacent belt 16 running slow, i.e. make the middle fast and both sides slow.

b) If one of the belts 16 has recovered from the blocked light beam and the other belts 16 has not recovered from the blocked light beam and still has been blocked, the belt 16 corresponding to the still blocked light beam is stopped and the buffer belt conveyor 2 is stopped.

d) And respectively carrying out corresponding operations according to the blocked light beam conditions.

4. When the light beam to be interrupted is discontinuous

The interrupted discontinuous light beam is divided into several continuous interrupted light beams, and then the above-mentioned point 3 operation is performed on each interrupted light beam in turn.

5. The second dual-drive belt unit 21, the third dual-drive belt unit 22 and the fourth dual-drive belt unit 23 are used for further separation when the first dual-drive belt unit 20 is insufficiently separated, and the control thereof is referred to the control method of the first dual-drive belt unit 20.

6. Control of the buffer belt conveyor 2

1) Starting the system initially;

2) When the package is conveyed and does not reach a certain distance, the first light curtain electric object measuring sensor 5 stops running when detecting the arrival of the package, and starts after the package which is conveyed reaches a certain distance.

3) When there are a plurality of side-by-side packages, the operation is stopped when the packages being processed leave the first light curtain electric measuring object sensor 5 (the blocked light beam is reset), and the packages being conveyed are started after reaching a predetermined distance.

The utility model discloses a multiunit dual drive belt unit's multistage differential separation realizes carrying in proper order the single piece separation of package side by side, satisfies the automatic demand of sweeping the sign indicating number, reduces the automatic fault-tolerant rate of sweeping the sign indicating number, the flow that the steerable package was carried simultaneously. So that manual intervention is not needed, the overall efficiency is improved by more than 98 percent, and the cost is reduced by 50 percent.
