The multi-layer lifting type material carrying pieces are arranged on the belt surface of the conveying belt at intervals along the vertical direction. Specifically, the lifting type material carrying piece can be arranged on the inner side surface or the outer side surface of the belt surface. The lifting type material carrying piece is arranged on the outer side face of the belt face.

In this embodiment, the driving means may be a motor. The rack is provided with a driving wheel and a driven wheel. The conveyer belt cover is located action wheel and is driven the driving wheel and tensioning, and the motor passes through belt or sprocket drive and connects in the action wheel, and then drives conveyer belt and rotate along conveyer belt's circumferencial direction for install the lift type material carrying piece on conveyer belt's the area face and carry to another place along conveyer belt's circumferencial direction from one place.

The belt surface of the conveyor belt 12 is disposed in the vertical direction. The lifting carriage 13 of each layer comprises a plurality of carriage units 131 for the carriage to rest on. A plurality of loading units 131 are disposed along the circumferential direction of the conveyor belt 12.

The lifting devices are arranged on the belt surface of the conveying belt. The plurality of lifting devices are arranged at intervals along the circumferential direction of the conveying endless belt, and each lifting device is arranged along the vertical direction. A row of corresponding material carrying units of the multi-layer lifting material carrying piece are arranged on the lifting device, and the material carrying units of the row are arranged at intervals along the vertical direction. The height of each row of carrying units of the multi-layer lifting carrying piece is independently adjusted through a plurality of lifting devices.

The loading unit 131 has a butt end and a connecting end opposite to each other. The connecting end is connected with the lifting device of the belt surface of the conveying belt. The abutting ends of the plurality of loading units 131 are disposed obliquely upward toward the rear of the advancing direction of the conveying belt 12. The loading unit 131 is mounted with the output member 14. The output member 14 is for outputting a express item placed on the loading unit 131.

The annular multi-layer automatic pre-dispenser has opposite first and second sides. The automatic code scanning and packing machine 2 is arranged on the first side of the annular multi-layer automatic pre-separating machine 1. A plurality of automatic code scanning and bagging machines 2 are arranged along the circumferential direction of the conveying endless belt 12. The output end of the conveyer belt of the automatic code scanning and packing machine 2 is aligned with the butt joint end of the material loading unit. In this embodiment, the output end of the conveyer belt of the automatic code scanning and packing machine is higher than the butt joint end of the lifting type material carrying part, so that the express mail is pushed and ejected by the conveyer belt of the automatic code scanning and packing machine and falls on the material carrying unit of the lifting type material carrying part.

The linear automatic sorting line 4 is arranged on the second side of the annular multi-layer automatic pre-sorting machine 1. The plurality of linear automated sorting lines 4 are along the circumferential direction of the conveyor belt 12. The head end 41 of the linear automated sorting line 4 is aligned with the butt end of the loading unit.

In this embodiment, a pre-express delivery device 3 is installed between the head end 41 of the linear automatic sorting line 4 and the butt end of the second side of the annular multi-layer automatic pre-sorting machine 1. The pre-express delivery device 3 has a receiving end and an output end. The receiving end of the pre-express delivery transfer device 3 is arranged below the abutting end of the carrying unit. The delivery end of the pre-express delivery device 3 is connected to the head end 41 of the line automatic sorting line.

The express item placed on the carrying unit can be ejected, pushed and overturned by the output piece to be output in a dumping mode and the like. For example, when the output member is pushed to be output in a pushing manner, the output member may be a hydraulic cylinder. The express mail is pushed out of the butt joint end by the output part on the carrying unit so as to fall on the receiving end of the pre-express mail transfer and delivery device. The connector end is arranged below the butt end.

In the invention, the outer sides of the material carrying units (namely the material carrying hoppers) of each layer of the annular multi-layer automatic pre-sorting machine are inclined backwards and upwards, and the express items thrown by the automatic code scanning and packaging machine cannot be thrown out due to centrifugal force when the annular multi-layer automatic pre-sorting machine runs at high speed.

The multi-layer carrying units in the same row (each group) can automatically move up and down before or during passing through a lower packaging area (a plurality of pre-express item transfer and delivery device areas), one carrying unit loaded with express items is kept opposite to the pre-express item transfer and delivery device, and express items are thrown onto the pre-express item transfer and delivery device. The multi-layer material loading units in the same column (each group) can repeatedly move up and down in the package interval as required, so that the package quantity in unit time matched with a plurality of linear automatic sorting lines through the pre-sorting express delivery transfer device is realized.

The sorting flow of the matrix type express sorting system of the invention is as follows:

firstly, the butt joint ends of the material carrying units are positioned below or flush with the output end of a conveying belt of an automatic code scanning and packing machine by the height of the material carrying units of each row of lifting material carrying parts of a lifting device;

the method comprises the steps that the to-be-sorted express mail is conveyed to a carrying unit of a lifting carrying piece of a first layer through an output end of a conveying belt of an automatic code scanning and packaging machine, after the express mail is carried in all carrying units of the lifting carrying piece of the first layer, the lifting device adjusts the setting height of the carrying unit which does not carry the express mail, so that the butt joint end of the carrying unit of the lifting carrying piece of a second layer is arranged below or flush with the output end of the conveying belt of the automatic code scanning and packaging machine, when the express mail is conveyed to the carrying unit of the second layer, the express mail conveyed to the second side of a conveying belt is output by the output piece and falls on a pre-dividing express mail transfer and delivery device in a parabolic manner, then is conveyed to a head end of a linear automatic sorting line through the pre-dividing express mail transfer and delivery device, and finally is conveyed to a discharge port 42, and the discharge port is provided with the express mail which is loaded and delivered to the same destination.

According to the matrix type express mail sorting system, the setting height of the lifting type carrying pieces can be adjusted through the lifting device according to the situation of carrying express mail of the lifting type carrying pieces of each layer on the conveying ring belt, so that carrying units which do not carry or output express mail are aligned to the output end of the conveying belt of the automatic code scanning and packaging machine. In the invention, the express items are conveyed from the automatic code scanning and packaging machine to the material loading unit, output from the material loading unit by the output items and drop on the pre-express item transfer and delivery device, respectively drop in a parabolic manner, so that the output express items can be prevented from colliding with the express items on the adjacent material loading units, compared with the traditional annular cross sorting machine (shown in figure 1). In addition, because the oblique backward upward slope of carrying the material unit sets up for even if the automatic extension machine of annular multilayer is in advance with the functioning speed that is higher than traditional annular cross sorting machine, the express mail that carries the material unit to accept also can be lived by carrying the material unit under the great circumstances of centrifugal force, avoids the express mail to be got rid of in the corner of the conveying clitellum of the automatic extension machine of annular multilayer and flies, so can effectively improve express mail letter sorting efficiency.

When the automatic code scanning and package supplying machine is to load a layer of material loading unit and a section of lifting type material loading piece (a plurality of adjacent material loading units) is used for bearing the express mail, the lifting device is used for adjusting the height of a row of lifting type material loading pieces, so that the output end of the conveying belt of the automatic code scanning and package supplying machine is aligned with the empty material loading units of other layers, the automatic code scanning and package supplying machine does not need to wait for the material loading unit (when the existing automatic code scanning and package supplying machine is used for loading) for bearing the express mail to pass, the automatic code scanning and package supplying machine can load at any time, the package supplying and loading efficiency is quickened, and the express mail sorting efficiency is further improved.

The following describes the characteristics of small occupied area, high productivity, high manual efficiency, high equipment efficiency and the like of the matrix type express sorting system according to an embodiment.

Specifically, in this embodiment, four groups of 14 automatic code scanning and packing machines, one annular multi-layer automatic pre-sorting machine (three-layer lifting type material carrying elements are configured by the annular multi-layer automatic pre-sorting machine in total, 162 material carrying units are configured), four linear automatic sorting lines (224 material sorting outlets) and pre-sorting and transferring and delivering devices are configured.

When the running speed of the linear automatic sorting line is 1.6m/s and the running speed of the annular multi-layer automatic pre-sorting machine is 3m/s, the productivity per hour can reach 4 ten thousand pieces, the labor is used for about 30 people, and the occupied area is only 600 square meters.

When the trolley of the traditional annular cross sorting machine has express mail, the automatic code scanning and packaging machine supplying machine can only wait even if the automatic code scanning and packaging machine supplying machine is ready; when the lifting type material carrying piece of the annular multi-layer automatic pre-sorting machine is provided with the express mail, after the annular multi-layer automatic pre-sorting machine is lifted, the automatic code scanning and package supplying machine can still send the express mail to the lifting type material carrying piece of other layers of the annular multi-layer automatic pre-sorting machine.

When the traditional automatic code scanning and packing machine is used for feeding and clamping shells, the trolley of the traditional annular cross sorting machine can only be empty when no express items exist; the automatic code scanning and packing machine can still convey the earlier-cached express mail to the pre-express mail transfer and delivery device even if the machine is clamped, so that the annular multilayer automatic pre-sorting machine is not free of express mail output.

Between traditional annular cross sorting machine and traditional confession package platform, all have the contained angle between annular cross sorting machine and the outlet, cross the package and align the linking route and calculate complicacy, often have the contained angle to cross the phenomenon that the package is makeed mistakes. The automatic code scanning and packing machine and the annular multi-layer automatic pre-separating machine dynamically eliminate the hidden trouble that the traditional included angle cannot be processed by the angle matching of the automatic code scanning and packing machine and the annular multi-layer automatic pre-separating machine.

The conventional bag feeding table or sorting machine of the annular cross sorting machine can only idle or stop running to be inspected as long as one place fails. According to the sorting system and the sorting method, when the sorting machine fails, the automatic code scanning and bag supplying machine and the annular multilayer automatic pre-sorting machine can operate normally; when the automatic code scanning and bag supplying machine fails, the sorting machine and the primary sorting system operate normally, and only partial parts are affected, so that the sorting machine is not stopped to be inspected.

Traditional annular cross sorting machine and supply package platform are in efficiency height, speed, productivity size, are difficult to realize dynamic matching, and this kind of mismatch is difficult to balanced because of direct package between sorting machine and the supply package platform, brings a lot of difficulties for system integration design. The sorting system can dynamically consume flow and synchronous speed at any time according to the size of the working amount, is matched and balanced, is very convenient to operate, and ensures that the system is in optimal efficiency.

As the actual height of the sorting system is similar to that of the existing annular cross belt sorting equipment, double-layer stacking can be performed, and if the double-layer stacking is performed, the two ends are initially separated, so that the capacity of 8 ten thousand pieces per hour can be realized. A plant almost corresponds to the capacity of a logistic park.

The system is universal in port-in and port-out sorting, is compatible in large and small pieces and irregular pieces, is the direction of logistics sorting equipment in the future, and can make an important contribution to the large-scale development of logistics sorting.

The matrix type express mail sorting system can automatically control the express mail in the range of three codes (the forward codes of the express mail) arranged on the same linear automatic sorting line not to be loaded in the same row of multi-layer carrying units when receiving and delivering the express mail, because only then, the express mail in the same row of multi-layer carrying units can be completely unpacked (drop type throwing to pre-express mail transfer throwing) at one time when passing through the linear sorting line interval. The annular multi-layer automatic pre-sorting machine can automatically control the lower package according to the three-section code range of each corresponding straight line sorting line when the lower package is carried out in the lower package area, so that the total productivity is approximately equal to the sum of theoretical productivity of a plurality of straight line sorting lines at a certain speed. Although the total productivity can be improved through the primary separation equipment and a plurality of linear sorting lines according to the pre-separation principle, the manual number of the package is at least doubled, each linear sorting line is required to be connected with a plurality of package loading machines, the distance between the linear sorting lines is increased, and the utilization rate of the field is greatly reduced. If the number of the arranged straight line sorting lines exceeds 4, the advantages of the matrix type express sorting system are further improved, the matrix type express sorting system can be arranged in a three-dimensional mode, the number of layers of the straight line sorting lines is increased, the straight line sorting lines share grid openings, and sorting productivity of small express is increased again in multiple.

According to the annular multilayer automatic pre-sorting machine of the matrix type express sorting system, when express is required to be delivered to a corresponding linear sorting line (connected by pre-express transfer delivery), output pieces in a hopper in a material loading unit are subjected to proper speed transmission, so that the express is delivered to the pre-express transfer delivery device.

A pre-express item transfer and delivery device is arranged between the annular multi-layer automatic pre-sorting machine and the linear sorting machine. Wherein, three sides of the pre-express delivery transfer device are provided with baffle plates and two sections of driving belts are arranged. When the express delivery device is used for delivering the express delivery to the first section of driving belt, the first section of driving belt can rotate outwards, under the cooperation of the end face baffle plates, the express delivery is aligned, then the express delivery is quickly transferred to the second section of driving belt when the second section of driving belt does not contain the express delivery, the first section of driving belt waits for the delivery of a new express delivery, and the second section of driving belt delivers the express delivery to the straight line sorting line.

The linear automated sorting line may be cross-belt or other type.

In this embodiment, the end face of the abutting end of the loading unit is disposed at an angle to the belt surface, rather than being disposed in the same direction as the belt surface of the conveying belt. The design of the oblique end face of the material carrying unit enables the output end of the conveying belt of the automatic code scanning and bag supplying machine to be designed into a rectangle, and avoids the design of the oblique end face and other special shapes, thereby reducing the occupied area of the automatic code scanning and bag supplying machine.

An electro-hydraulic push rod is connected between the carrying unit 131 and the belt surface of the conveying belt. The two ends of the electric hydraulic push rod are respectively hinged with the lifting noise reduction of the belt surfaces of the material carrying unit and the conveying belt.

In some embodiments, the lifting device includes a housing box having first and second sides that are opposite to each other. The first side of holding case is connected in the area face of conveyer belt, and the guide way of vertical setting has been seted up to the second side of holding case. A slide block is arranged in the guide groove in a sliding way. The slider has opposite first and second ends. The first end of slider stretches to the outside of holding case, and the rack of vertical setting is installed to the second end of slider. The lifting motor is arranged in the accommodating box, the output end of the lifting motor is coaxially connected with a gear, and the gear is meshed with the rack. The lifting motor drives the sliding block to reciprocate up and down in the guide groove through the gear and the rack, so that a row of material carrying units can lift up and down along the belt surface of the conveying belt.
