Description

Technical Field

[0001] The utility model relates to the technical field of logistics piece sorting, in particular to a logistics piece sorting machine. Background Art

[0002] The existing express logistics is becoming increasingly busy, with an increasing number of items. Traditional technologies use manual identification for sorting, which is inefficient and prone to errors. Especially during special periods such as holidays, the number of logistics items increases several times. At this time, manual sorting can no longer meet the requirements. Therefore, some automatic conveying and sorting mechanisms have appeared on the market. They use CCD cameras to identify the recipient address on the top of the express package and sort it. Generally, after the CCD camera identifies the address, it pushes the package through the push plate on one side of the conveyor belt, while the express package is still in the conveying state. At this time, the push can easily cause some fast-moving packages to deviate when they are pushed out of the conveyor belt, and they cannot fall completely along the discharge chute, which is not very ideal.

If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0025] Reference Figures 1 to 7 The utility model proposes a logistics piece sorting machine, comprising a roller conveyor line 1, a photographing and identifying mechanism 2 capable of photographing items on the roller conveyor line 1, and a multi-group sorting and unloading mechanism 3. The roller conveyor line 1 comprises a feeding rack 11, a plurality of rollers 12 spaced apart on the feeding rack 11, and a feeding driver 13 capable of driving all the rollers 12 to rotate. Gaps 101 are formed between adjacent rollers 12. The sorting and unloading mechanisms 3 are arranged at intervals along the feeding direction of the roller conveyor line 1. The sorting and unloading mechanisms 3 comprise a lifting member 31 capable of passing through the gap 101 upward, a pushing member 32 capable of passing through the gap 101 upward and pushing items on the lifting member 31 to the left or right, and a unloading driving device capable of driving the lifting member 31 and the pushing member 32 to move.

[0026] In order to prevent logistics items and other items on the roller conveyor line 1 from falling from its left and right sides, two guardrails 111 are set on the top of the feeding rack 11, one on the left and one on the right. The upper surface of the guardrail 111 is higher than the highest point of the surface of the roller 12.

[0027] The feeding drive 13 adopts a motor, and a first sprocket is provided at the left end of all the rollers 12. All the first sprockets are connected together by the same chain. The output end of the motor is connected to one of the first sprockets through a sprocket chain mechanism, thereby driving these rollers 12 to rotate synchronously through the feeding drive 13 to transport logistics items and other items forward.

[0028] The left and right sides of the feeding rack 11 can be provided with a plurality of feeding chutes 15 capable of receiving items pushed down by the pushing member 32, and boxes or storage frames for receiving logistic items can be provided under the feeding chutes 15. Of course, if the logistic items are resistant to falling, the feeding chutes 15 can be eliminated, and a plurality of boxes capable of receiving logistic items can be provided directly on the left and right sides of the feeding rack 11.

[0029] The shooting identification mechanism 2 comprises a camera support 21 positioned on one side of the feeding rack 11 and a CCD camera 22 mounted on the camera support 21. The camera support 21 can be fixed or a roller can be provided at its bottom to make it movable.

[0030] In a preferred embodiment of the present invention, the sorting and unloading mechanism 3 further comprises a lifting seat 33 located below the drum 12. The output end of the unloading drive device is connected to the lifting seat 33 to drive it to move up and down. The pusher 32 is a vertical plate fixed to the lifting seat 33. The pusher 32 is provided with a pushing inclined surface 321 that can push the items to the left or right when it moves upward. A support plate 34 is provided on the lifting seat 33 and can move up and down relative to the lifting seat 33. The lifting seat 33 and the support plate 34 are connected by a compressible elastic member 35 so that the elastic member 35 can push the support plate 34 upward when the lifting seat 33 moves upward. The pusher 31 includes two top plates 311 fixed to the support plate 34 in a front-to-rear manner. The two top plates 311 correspond to the two gaps 101 respectively. The feed rack 11 is provided with a limiter 16 that can abut against the support plate 34 when the upper surface of the top plate 311 is not lower than the highest point of the guardrail 111. The pusher 32 is located between the two top plates 311 , and the support plate 34 is provided with an avoidance groove 341 capable of avoiding the pusher 32 .

[0031] The above-mentioned limiting member 16 is preferably a cross bar on the main frame of the feeding rack 11, referring to Figures 4 to 6The working principle of this scheme is as follows: when the logistics piece is conveyed forward along the roller conveyor line 1, the shooting recognition mechanism 2 recognizes the barcode or QR code on the logistics piece and reads the information therein. Then the roller conveyor line 1 conveys the logistics piece to the top of the corresponding sorting and unloading mechanism 3. At this time, the upper surface of the top plate 311 of the sorting and unloading mechanism 3 is slightly lower than the highest point of the roller 12, generally 5 mm or 10 mm lower. The state at this time is as follows: Figure 4 Then the unloading driver of the sorting unloading mechanism 3 works, driving the lifting seat 33, the pusher 32 on the lifting seat 33, the support plate 34, and the top plate 311 on the support plate 34 to move upward. During this process, the two top plates 311 lift the corresponding logistics items until the support plate 34 contacts the limiter 16. At this time, the upper surface of the top plate 311 is higher than the upper surface of the guardrail 111 or is flush with the upper surface of the guardrail 111. The state at this time is as shown in FIG. Figure 5 Then, the lifting seat 33 and the push plate continue to move upward. During this process, the support plate 34 is supported, and the support plate 34 and the top plate 311 on it no longer rise. However, the push plate continues to rise, and the pushing inclined surface 321 on it pushes the logistics parts on the top plate 311 to the left or right, so that the logistics parts fall into the corresponding discharge chute 15 and finally fall into the corresponding box or storage frame.

[0032] As a specific embodiment of the above-described solution, a vertical first guide sleeve 36 is provided on the lifting seat 33, and a first guide post 37 is fixed to the support plate 34, which slides with the first guide sleeve 36. An elastic member 35 is a compression spring that fits over the first guide post 37. The upper end of the compression spring abuts the support plate 34, and the lower end of the compression spring abuts the lifting seat 33 or the first guide sleeve 36. A fixed seat 39 is fixed to the feeder frame 11, located below the lifting seat 33. The unloading drive device includes a cylinder 38 mounted on the fixed seat 39, the output shaft of which is connected to the lifting seat 33. A vertical second guide sleeve 303 is provided on the fixed seat 39, and a second guide post 304 is fixed to the lifting seat 33, which slides with the second guide sleeve 303.

[0033] In certain solutions of the present invention, the above-mentioned material unloading drive device may also adopt other structural forms, such as an electric cylinder, an oil cylinder, etc.

[0034] In order to further improve the accuracy of the activation timing of the sorting and unloading mechanism 3, a plurality of sensors 14 capable of sensing the position of the items on the roller 12 are arranged at intervals on the feeding rack 11. The sensors 14 are preferably photoelectric sensors, each of which corresponds to a group of sorting and unloading mechanisms 3. When a courier passes through the working area of ​​the corresponding photoelectric sensor, the photoelectric sensor collects this information and sends this information to the central control system. Finally, the corresponding sorting and unloading mechanism 3 is activated after the set time, and the courier can be removed from the roller conveyor line 1.

[0035] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
