Description

Technical Field

[0001] This utility model relates to the technical field of express delivery, and in particular to an unmanned conveying and sorting equipment for small logistics items. Background Technology

[0002] Unmanned sorting and conveying equipment for small parcels is a type of machinery that can automatically classify, sort, and convey small items. It primarily relies on advanced sensor technology, a computer control system, and automated conveying equipment to achieve unmanned loading of goods. This equipment not only improves sorting efficiency but also reduces the error rate of manual operation.

[0003] The existing Chinese utility model patent with application number CN202420070406.6 relates to an automatic logistics conveying and sorting machine, which includes a feeding plate, a moving component, a connecting frame, a connecting rod, a roller, a sliding plate, a baffle, a support frame, a removal component, and a spring, etc., which can avoid the problem of smaller logistics items being mixed with larger logistics items, which would make them difficult to find later.

[0004] The existing express delivery method is usually to have people manually deliver the express packages on both sides of the conveyor line, place the packages on the delivery table, and then send the packages to the sorting machine through the delivery table. However, manual processing is costly.

[0005] Furthermore, most unmanned parts supply systems use a single-row supply method, which results in low supply efficiency. Increasing supply efficiency requires higher equipment costs and also increases the floor space required. Utility Model Content

[0006] To address the aforementioned technical problems, this invention employs a de-stacking device to initially separate packages, reducing the probability of package stacking. After initial separation, packages enter a single-item separation device for further separation, allowing them to enter a sequential state before proceeding to a side-mounting device. This side-mounting device ensures that packages exit at a predetermined exit point, improving the efficiency of the packing and scanning devices. Following the side-mounting device, packages enter the packing and scanning device, which maintains spacing between them, ensuring they enter the identification device sequentially at certain intervals. The scanning device acquires the package's waybill information and, through integration with the business system, matches it to sorting slots. Finally, packages enter the delivery line. Notably, this invention utilizes a double-row operation in the de-stacking, side-mounting, and delivery line processes to increase throughput and save costs.

[0007] Furthermore, the de-stacking device adopts a stacking separation conveyor belt drop splicing, which allows the express packages to be separated by the drop during the transmission process. A de-stacking canopy is provided above the support of the de-stacking device 1. The de-stacking canopy is equipped with a device that can obtain the relevant position information of the express packages. This device can be a vision machine or a photoelectric sensor.

[0008] The speed of the stacking separation conveyor belt can be adjusted according to the degree of stacking of the express items. Express item baffles are installed between each section of the stacking separation conveyor belt with a drop to prevent missing items.

[0009] Furthermore, the destacking device is equipped with a partition device that divides the stack separation conveyor belt into left and right sides. Each side of the stack separation conveyor belt is controlled independently by a servo controller, so that the destacking device can achieve double-row operation.

[0010] Furthermore, the vision machine outputs control signals to the servo controller to enable rapid start-stop, acceleration, and deceleration of the stacking separation conveyor belt, thereby achieving further separation of the items. In particular, when the vision machine does not detect any items in the destabilization device, the servo controller can control the speed of the stacking separation conveyor belt to ensure the production capacity of the entire line or to put the destabilization device into standby mode to save energy.

[0011] Furthermore, such as Figure 2-5 As shown, the single-piece separation device of this utility model consists of multiple single-piece separation modules. Each module includes a single-piece separation belt, a single-piece separation control device, and structural components. The number of modules can be adjusted according to workload. This utility model uses six single-piece separation belts per row, with four rows totaling 24 belts. Each belt is individually driven by the single-piece separation control device. The control device moves the belts on the single-piece separation modules by driving the belt rollers. A servo motor can be used as the single-piece separation control device.

[0012] The single-item separation device is equipped with a single-item separation canopy, on which a vision sensor (not shown) is mounted. This sensor can acquire information such as the relative position and size specifications of the packages on the single-item separation device in real time. The vision sensor transmits the acquired information to the system for algorithm matching and outputs corresponding instructions to the single-item separation control device. The single-item separation control device outputs start, acceleration, and deceleration instructions to the servo controller of the corresponding module through the differential speed principle, thereby achieving further separation of the packages. This can convert the packages from parallel to serial state so that they can enter the next transmission stage, thus realizing single-item separation.

[0013] Furthermore, such as Figure 6The edge-aligning device includes a left edge-aligning roller and a right edge-aligning roller. The left edge-aligning roller is driven independently by a first edge-aligning motor, and the right edge-aligning roller is driven independently by a second edge-aligning motor. Although the left and right edge-aligning rollers are driven independently, their operating speeds can be the same. The left and right edge-aligning rollers together form a roller edge-aligning machine. The rollers of the roller edge-aligning machine can be arranged in a conical pattern from the inlet to the outlet of the package, so that the package is aligned to the left and right when passing through the edge-aligning device. The roller edge-aligning machine aligns packages that are entered from different points to the left and right. The output end has two fixed output points on the left and right, and the package can enter the pull-out and scanning device from the designated position.

[0014] Furthermore, such as Figure 7 As shown, the barcode scanning device includes a barcode scanning device and a barcode scanning device installed on the barcode scanning bracket. The barcode scanning device includes an upper barcode scanning device, a lower barcode scanning device, a front barcode scanning device, a rear barcode scanning device, a left barcode scanning device, and a right barcode scanning device, so as to realize all-round barcode scanning of express items.

[0015] The tensioning device includes at least a first tensioning belt and a second tensioning belt. Both the first and second tensioning belts are individually controlled by a servo controller, enabling differential motion between them. It should be noted that there is a certain gap between the first and second tensioning belts. The lower-level scanning device is located below the first and second tensioning belts. The lower-level scanning device can identify the contact surface between the tensioning belts and the express shipment through the gap between the tensioning belts.

[0016] The difference in speed between the first and second tension belts increases the spacing between express items, ensuring that the items enter the barcode scanning array composed of 6 cameras in a certain order at certain intervals, thereby obtaining the waybill information.

[0017] It should be noted that the barcode scanning device can be equipped with a grayscale meter to further determine the stacking status. If stacking is detected, the package is transported from the conveyor line to the manual operation area. The return line (not shown in the figure) can be located at one end of the storage chute. The package is de-stacked by returning it to its initial state via the return line.

[0018] In particular, the manual operation area 71 is equipped with a switch (not shown) that can switch between automatic and manual operation modes. In automatic mode, the balance wheel feeds the parts, and in manual mode, the parts are manually fed. The parts are picked up from the storage chute 7 and then manually fed.

[0019] Furthermore, after the stretching and scanning devices, the packages enter the feeding line, which uses a combination of a balance wheel and a belt. Specifically, it includes a feeding belt line and a balance wheel line. Several feeding stations are set on the side of the balance wheel line. After being identified, the packages enter the feeding stations through the balance wheel line. A manual operation area is set on the side of the feeding station, allowing staff to manage both the operating station and the feeding line, facilitating manual operation.

[0020] Specifically, the conveyor line is equipped with a belt-driven feeder wheel. The feeder platform is divided into a front group A and a rear group B. The belt-driven feeder wheel is located at the rear of group A and the front of group B. The belt-driven feeder wheel can transport express items from the conveyor line to the feeder wheel.

[0021] Specifically, after the information is captured by the pull-out and scanning devices, the express package enters the balance wheel line and then enters the feeding table in sequence. When the number of express packages is large, the express packages can also enter the conveyor line simultaneously. After passing through a certain distance, the express package enters the balance wheel of the belt feeding line and enters the balance wheel line under the action of the belt feeding line balance wheel, and then enters the rear B group of the feeding table 6.

[0022] It should be noted that, under normal circumstances, if a package is not identified, it can be transported to the manual operation area via the delivery line and returned to the initial stage for de-stacking, thus avoiding excessive return flow indicators for the sorting machine.

[0023] In addition, after the package has been scanned, it enters the balance wheel line. The sensors on the balance wheel line continuously track the location and status of the package, and handle information errors caused by jams or irregular movement of the package. It can also adjust the package throughput in real time by combining the package supply status of the supply station and the empty or full status of the trolleys on the sorting machine.

[0024] It should be noted that the sensor module on the balance wheel line can be a photoelectric module on the balance wheel, or a camera mounted on the balance wheel for tracking. That is, the sensor can be integrated with the balance wheel, or it can work above or to the side of the balance wheel.

[0025] It should also be noted that the end of the feeding station is the final feeding station, and the manual operation area is preferably located on the side of the final feeding station, close to the storage chute for convenient manual work. The final feeding station is generally not used in automatic feeding mode; it is usually in manual operation mode, while the other feeding stations are in automatic operation mode. For example, in this utility model, there are two groups of feeding stations, A and B, each group consisting of one feeding station. The express parcel enters the frontmost feeding station first from A to B, and then proceeds sequentially to the rearmost feeding station. If the work station in group A can meet the work requirements, there is no need to start the work station in group B.

[0026] For sensor malfunctions caused by dirt, dust, etc., the monitoring platform or audible and visual alarm device can remind the user to handle the issue in real time.

[0027] Optoelectronic modules can use signal sensors, such as cameras and laser sensors.

[0028] It should be noted that the stacking device, single-piece separation device, and feeding line of this utility model can still operate in a single-row state to adapt to the requirements of different working environments, which greatly improves the practicality of this utility model device.

[0029] This invention employs a de-stacking device to disperse stacked parcels during transportation; a single-piece separation device to stagger the front and rear positions of parcels transported side-by-side, allowing for single-piece output; a side-positioning device to separate parcels on the same conveyor line towards the edges of the transport line, dividing the parcels on the same line into two parallel lines; and a spacing device to increase the front-to-back distance between parcels, facilitating subsequent individual scanning and analysis. The coordinated use of these devices enhances the automation level of sorting, reduces labor costs, and thus improves the practicality of the device. This invention, by employing a double-row operation in the de-stacking device, side-positioning device, and feeding line, increases the conveying throughput and saves costs. This invention has beneficial effects. Attached Figure Description

[0039] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0040] like Figures 1-7 As shown:

[0041] This invention uses a de-stacking device 1 to initially separate packages, reducing the probability of package stacking. After initial separation, the packages enter a single-item separation device 2, which further separates them, allowing them to enter a sequential state before entering a side-mounting device 3. The side-mounting device 3 ensures that the packages exit the device at a predetermined exit point, improving the efficiency of the packing and scanning devices. After the side-mounting device 3, the packages enter a packing and scanning device 4, which separates the packages to ensure they enter the identification device sequentially at certain intervals. The scanning device can obtain the package's waybill information and, through integration with the business system, match it to the sorting slots. The packages then enter the feeding line 5. Notably, this invention employs a double-row operation method in the de-stacking, side-mounting, and feeding lines to increase throughput and save costs.

[0042] Furthermore, such as Figure 2 The de-stacking device 1 uses a drop-type splicing conveyor belt 11 to separate the stacked packages during the transmission process. A de-stacking canopy 102 is provided above the support of the de-stacking device 1. The de-stacking canopy is equipped with a device that can acquire the relevant position information of the packages. This device can be a vision machine or a photoelectric sensor.

[0043] The speed of the stacking separation conveyor belt 11 can be adjusted according to the degree of stacking of express items. Express item baffles 12 are provided between each section of the stacking separation conveyor belt 11 with a drop to prevent missing items.

[0044] Furthermore, the destacking device 1 is equipped with a partition device 101, which divides the stack separation conveyor belt 11 into left and right sides. Each side of the stack separation conveyor belt is controlled separately by the servo controller 13, so that the destacking device can achieve double-row operation.

[0045] Furthermore, the vision machine outputs control signals to the servo controller to enable rapid start-stop, acceleration, and deceleration of the stacking separation conveyor belt 11, thereby achieving further separation of the items. In particular, when the vision machine does not detect any items in the destabilization device, the servo controller can control the speed of the stacking separation conveyor belt 11 to ensure the production capacity of the entire line or to put the destabilization device into standby mode, saving energy.

[0046] Furthermore, such as Figure 2-5 As shown, the single-piece separation device 2 of this utility model consists of multiple single-piece separation modules. Each single-piece separation module includes a single-piece separation belt 27, a single-piece separation control device 201, and structural components. The single-piece separation modules can be adjusted according to the workload. This utility model uses six single-piece separation belts 27 per row, with four rows, totaling 24 single-piece separation belts. Each single-piece separation belt is individually driven by the single-piece separation control device 201. The single-piece separation control device 201 drives the belts on the single-piece separation modules by driving the belt rollers 28. The single-piece separation control device 201 can be a servo motor.

[0047] The single-item separation device 2 is equipped with a single-item separation canopy 29 above it. A vision sensor (not shown) is installed on the single-item separation canopy 29. This sensor can acquire information such as the relative position and size of the packages on the single-item separation device 2 in real time. The vision sensor transmits the acquired information to the system, performs algorithm matching, and outputs corresponding instructions to the single-item separation control device 201. The single-item separation control device 201 outputs start, acceleration and deceleration instructions to the servo controller of the corresponding module through the differential speed principle, so as to further separate the packages. The packages can be converted from parallel to serial state and enter the next transmission link. Therefore, single-item separation is achieved.

[0048] Furthermore, such as Figure 6The edge-aligning device 3 includes a left edge-aligning roller 31 and a right edge-aligning roller 32. The left edge-aligning roller 31 is driven independently by a first edge-aligning motor 301, and the right edge-aligning roller 32 is driven independently by a second edge-aligning motor 302. Although the left and right edge-aligning rollers are driven independently, their speeds can be the same during operation. The left and right edge-aligning rollers form a roller edge-aligning machine. The rollers of the roller edge-aligning machine can be arranged in a conical shape from the inlet end to the outlet end of the express package, so that the express package can be aligned to the left and right sides when passing through the edge-aligning device. Through the roller edge-aligning machine, express packages that are entered from different points are aligned to the left and right sides. There are two fixed output points on the left and right sides at the output end, and the express package can enter the pull-out and scanning device 4 from the designated position.

[0049] Furthermore, such as Figure 7 As shown, the pull distance and scanning device 4 includes a scanning device and a pull distance device installed on the pull distance scanning bracket 49. The scanning device includes an upper scanning device 41, a lower scanning device 42, a front scanning device 46, a rear scanning device 45, a left scanning device 44, and a right scanning device 43, so as to realize all-round scanning of express items.

[0050] The tensioning device includes at least a first tensioning belt 410 and a second tensioning belt 411. Both the first tensioning belt 410 and the second tensioning belt 411 are individually controlled by a servo controller, which can realize differential motion between the two. It should be noted that there is a certain gap between the first tensioning belt 410 and the second tensioning belt 411. The lower-level scanning device 42 is located on the lower side of the first tensioning belt 410 and the second tensioning belt 411. The lower-level scanning device 42 can identify the contact surface between the tensioning belt and the express item through the gap between the tensioning belts.

[0051] The difference in speed between the first tension belt 410 and the second tension belt 411 is used to increase the spacing between express items, thereby ensuring that the items enter the barcode scanning array composed of 6 cameras in a certain interval order to obtain the waybill information.

[0052] It should be noted that the barcode scanning device can be equipped with a grayscale meter to further determine the stacking status. If stacking is detected, the package is transported from the conveyor line to the manual operation area. The return line (not shown in the figure) can be located at one end of the storage chute. The package is de-stacked by passing through the return line to its initial state.

[0053] Specifically, 71 is the manual operation area. The manual operation area 71 is equipped with a switch (not shown in the figure) that can switch between automatic and manual working modes. In automatic mode, the balance wheel line 52 supplies parts, and in manual mode, parts are manually loaded. The parts are taken from the storage chute 7 and then manually supplied.

[0054] Furthermore, after the stretching and scanning device 4, the express package enters the feeding line 5. The feeding line 5 adopts a combination of a balance wheel and a belt. Specifically, it includes a conveyor line 51 and a balance wheel line 52. Several feeding platforms 6 are provided on the side of the balance wheel line 52. After being identified, the express package enters the feeding platform 6 through the balance wheel line 52. A manual operation area is provided on the side of the feeding platform 6. The staff can take care of the operating platform, the feeding line 5, and the storage chute 7 at the same time, realizing the function of switching between automatic and manual operation.

[0055] Specifically, a conveyor line swing wheel 502 is provided on the conveyor line 51. The feeding platform 6 is divided into a front A group and a rear B group. The belt feeding line swing wheel 502 is located at the rear of the A group and the front of the B group. The belt feeding line swing wheel 502 can transport express items on the conveyor line 51 to the swing wheel line.

[0056] Specifically, after the information is captured by the pull-out and scanning devices, the express package enters the balance wheel line 52, and then enters the feeding table 6 in sequence. When the number of express packages is large, the express packages can enter the conveyor line 51 simultaneously. After passing through a certain distance, they enter the belt feeding line balance wheel 502. Under the action of the belt feeding line balance wheel 502, they enter the balance wheel line 52 and then enter the rear B group of the feeding table 6.

[0057] If a package is not identified, it can be transported to the manual operation area 71 via the supply line 5, returning to the initial stage for de-stacking, thus avoiding excessive return flow index of the sorting machine.

[0058] In addition, after the package has been scanned, it enters the swing wheel line 52. The sensors on the swing wheel line 52 continuously track the location and status of the package, and handle information errors caused by jamming or irregular movement of the package. It can also adjust the package throughput in real time by combining the package supply status of the supply station and the empty or full status of the trolleys on the sorting machine.

[0059] It should be noted that the sensor module on the balance wheel line 52 can be a photoelectric module on the balance wheel, or a camera mounted on the balance wheel for tracking. That is, the sensor can be integrated with the balance wheel, or it can work above or to the side of the balance wheel.

[0060] It should also be noted that the end of the feeding station 6 is the end feeding station 61, and the manual operation area 71 is preferably located on the side of the end feeding station 61, close to the storage chute 7 for convenient manual operation. The end feeding station 61 is generally not used in automatic feeding mode, and the end feeding station 61 is generally in manual operation mode, while the other feeding stations 6 are in automatic operation mode. For example, in this utility model, the feeding stations 6 are divided into two groups, A and B, with three feeding stations in each group. The express mail enters the front feeding station first from A to B, and then proceeds to the rear feeding stations in sequence. If the work station of the A group can meet the work requirements, there is no need to start the rear feeding station of the B group.

[0061] For sensor malfunctions caused by dirt, dust, etc., the monitoring platform or audible and visual alarm device can remind the user to handle the issue in real time.

[0062] Optoelectronic modules can use signal sensors, such as cameras and laser sensors.

[0063] It should be noted that the stacking device, single-piece separation device, and feeding line of this utility model can still operate in a single-row state to adapt to the requirements of different working environments, which greatly improves the practicality of this utility model device.

[0064] The servo motor and servo controller of this utility model can be selected according to the specific working environment. Those skilled in the industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0065] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
