Description

Technical Field

[0001] This utility model relates to the field of logistics technology, and more specifically, to a fully automatic package feeding device for dual-item flow and multi-item flow. Background Technology

[0002] With the rapid development of the logistics sorting industry, improving the speed and efficiency of sorting equipment has become a focus of industry attention. How to improve the efficiency of existing sorting machines has become a top priority for logistics sorting centers. Currently, most mail processing centers use manual semi-automatic parcel feeders for loading, with an actual loading efficiency of about 1,700 pieces / hour per person. To meet the requirement of loading ≥10,000 pieces / hour in a single feeding area, at least 6 manual semi-automatic parcel feeders are needed in a single feeding area. This results in a large area occupied by the feeding area and a reduction in the number of available compartments. Moreover, continuous feeding by personnel will gradually lead to fatigue, and the loading efficiency will gradually decrease. This model cannot meet the development requirements of speeding up and improving the efficiency of sorting machines.

[0003] In summary, it is necessary to invent a sorting mode that is high-speed, efficient and occupies a small area. Therefore, this utility model proposes a fully automatic packing device for dual-flow and multi-flow processes. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a fully automatic package feeding device for dual-flow and multi-flow operations, which provides high-speed, high-efficiency, and space-saving fully automatic package feeding operations for dual-flow and multi-flow operations.

[0005] This utility model is achieved through the following technical solution: a fully automatic package feeding device for dual-flow and multi-flow mail storage, including a mail storage line, one end of which is provided with a stacking separation system, which is composed of several inclined servo belt conveyors. The stacking separation system has a multi-channel single-item separation system on the side away from the mail storage line. The multi-channel single-item separation system includes a multi-channel mail centering machine and a matrix servo narrow-band separation belt conveyor. The multi-channel single-piece separation system is equipped with a stacking detector, which is used to detect the presence of stacked pieces; The multi-channel single-item separation system is equipped with a multi-channel swing wheel sorter on the side away from the stacked item separation system. The multi-channel swing wheel sorter is used to sort mail. Each output end of the multi-channel swing wheel sorter is equipped with several fully automatic package feeders. It also includes a controller, and the mail storage line, stacked item separation system, multi-channel single item separation system, stacked item detector and multi-channel swing wheel sorter are all connected to the controller via signal.

[0006] Furthermore, the stacking separation system also includes several first cameras, the field of view of which is located at the center point of each servo belt, and the first cameras are signal-connected to the controller.

[0007] Furthermore, the multi-channel single-piece separation system also includes a second camera, the center of the second camera's field of view is located at the center point of the matrix servo narrow-band separation belt conveyor, and the second camera is signal-connected to the controller.

[0008] Furthermore, the stacked component detector includes a housing, which is mounted on a multi-channel single-component separation system. A grayscale camera is fixed inside the housing and is connected to the controller via signals.

[0009] Furthermore, a grating detector is fixed inside the housing, and the grating detector is connected to the controller signal.

[0010] Furthermore, a tension belt conveyor is installed between the multi-channel single-piece separation system and the multi-channel swing wheel sorter.

[0011] Furthermore, the bottom of the tension belt conveyor is equipped with several magnetic proximity switches, which are connected to the controller signal.

[0012] Furthermore, a third camera is mounted on the tension belt conveyor, with the center of the third camera's field of view located at the center point of the tension belt conveyor, and the third camera is connected to the controller signal.

[0013] Furthermore, one of the outputs of the multi-channel balance wheel sorter is connected to the mail storage line.

[0014] Furthermore, the fully automatic bag feeder includes several short-distance belt conveyors connected by transition sections, each equipped with reflective strips.

[0015] The technical solution of this utility model has at least the following beneficial effects: In operation, after being opened, small mail packages are conveyed along a transport line and then stacked on a mail storage line. The mail storage line is linked to a package separation system, which sequentially feeds the mail into the separation system. Several angled servo conveyors in the separation system utilize an incline to separate the packages. The servo conveyors can control their conveyor speed, thereby enhancing the separation effect through acceleration and deceleration, ultimately outputting a single layer of randomly arranged packages.

[0016] Unordered packages in a single layer enter a multi-channel single-item separation system. This system first uses a matrix servo narrow-band separation conveyor to control the transport speed of packages at each matrix, separating adjacent packages into single-item columns. At this point, although the packages are in a single column, they are distributed in various positions and not arranged in a straight line. A multi-channel mail centering machine further processes the packages, aligning them towards the center line of the transport process, forming a neat single-item package flow.

[0017] The packages will then enter the multi-channel swivel sorter, which will automatically sort the packages and send them to various fully automatic packing machines. The fully automatic packing machines will then pack the packages, completing the entire process automatically. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following detailed description illustrates the specific implementation method: Example 1 As attached Figures 1-8 As shown, a fully automatic package feeding device for dual-flow and multi-flow mail storage includes a mail storage line 1, which is a conventional belt conveyor. One end of the mail storage line 1 is equipped with a stacking separation system 2, which consists of several inclined servo belt conveyors 201. The several inclined servo belt conveyors 201 are combined to form several ramps.

[0024] The stacked item separation system 2 is provided with a multi-channel single item separation system 3 on the side away from the mail storage line 1. The multi-channel single item separation system 3 includes a multi-channel mail centering machine 301 and a matrix servo narrow belt separation conveyor 302. The multi-channel mail centering machine 301 is a roller-type centering machine, and the matrix servo narrow belt separation conveyor 302 is composed of multiple parallel narrow conveyor belts.

[0025] The multi-channel single-piece separation system 3 is equipped with a stacked component detector 4, which is used to detect whether stacked components exist.

[0026] A multi-channel single-item separation system 3 is provided on the side away from the stacked item separation system 2. The multi-channel swing wheel sorting machine 5 is a swing wheel sorting machine in the prior art. The multi-channel swing wheel sorting machine 5 is used to sort mail. Each output end of the multi-channel swing wheel sorting machine 5 is provided with several fully automatic package feeders 7. The fully automatic package feeders 7 are fully automatic package feeders in the prior art.

[0027] It also includes a controller, which is a PLC. The mail storage line 1, the stacked item separation system 2, the multi-channel single item separation system 3, the stacked item detector 4, and the multi-channel swing wheel sorter 5 are all connected to the controller via signals.

[0028] The stacking separation system 2 also includes several first cameras, the field of view of the first cameras is located at the center point of each servo belt 201, and the first cameras are signal connected to the controller.

[0029] The multi-channel single-piece separation system 3 also includes a second camera. The center of the field of view of the second camera is located at the center point of the matrix servo narrow-band separation belt conveyor 302. The second camera is connected to the controller signal.

[0030] In operation, after being opened, small mail packages are conveyed to the mail storage line 1 via a transport line. The mail storage line 1 is linked with the stacking and separation system 2 to ensure that the mail is fed into the stacking and separation system 2 in an orderly manner. Several inclined servo conveyors 201 in the stacking and separation system 2 can separate the mail by climbing an incline and removing stacks. The principle is based on the influence of slope and gravity. If there are stacked packages, during the climb, due to the change in the center of gravity and the change in the angle of the contact surface, the upper packages can easily slide backward or roll off naturally due to gravity, thus achieving de-stacking. The servo conveyors 201 can control the conveying speed, thereby enhancing the separation effect of overlapping packages through acceleration and deceleration, and finally outputting a single layer of disordered packages.

[0031] The stacking and separating system 2 is equipped with a first camera (not shown in the figure). The first camera can capture images of the packages on the stacking and separating system 2, which can be used to identify the images and then fine-tune the transportation speed to improve the stacking and separating effect.

[0032] A single-layer, randomly arranged package enters the multi-channel single-item separation system 3. The multi-channel single-item separation system 3 first uses a matrix servo narrow-band separation conveyor 302, which consists of multiple narrow conveyor belts. By adjusting the transmission speed of the packages at each matrix, that is, by adjusting the speed to create a distance difference between two side-by-side packages, adjacent packages in the multi-channel single-item separation system 3 are separated to form a single-item package column.

[0033] The multi-channel single-item separation system 3 is equipped with a second camera (not shown in the figure). The second camera will image the packages on the matrix servo narrow-band separation belt conveyor 302, which will facilitate the separation of side-by-side packages by recognizing the images and then fine-tuning the transport speed.

[0034] Although the packages are now in a single column, they are distributed in various positions and are not arranged in a straight line. The multi-channel mail centering machine 301 can further process the packages. The multi-channel mail centering machine 301 consists of several roller groups that are inclined from both sides towards the center line. As the rollers rotate, the packages in each position can be moved towards the center line of the conveying process, forming a neat single-column package flow.

[0035] The packages will then enter the multi-channel swing wheel sorter 5, which will automatically sort the packages. Through the pushing action of the swing wheels of the multi-channel swing wheel sorter 5, the packages will be sent to each fully automatic package feeder 7, which will pack the packages and complete the operation process automatically.

[0036] Example 2 The difference from the above embodiments is that the stacked component detector 4 includes a housing 401, which is mounted on the multi-channel single-component separation system 3. A grayscale camera 402 is bolted inside the housing 401 and is connected to the controller for signal transmission. A grating detector 403, model ESCL-1620L1NRYL-2, is also screwed inside the housing 401 and is connected to the controller for signal transmission.

[0037] Even after passing through the stacking separation system 2, stacked parts may still occur, thus requiring the identification of packages that have not been completely separated. The housing 401, mounted on the multi-channel single-piece separation system 3, can acquire grayscale images of the package and use grayscale edge recognition to identify edges, thereby determining whether stacked parts exist. However, when encountering thin or light components, the grayscale camera 402 may have difficulty effectively distinguishing edges. Therefore, a grating detector 403 can be installed to measure using the principle of grating overlapping fringes. Since the overlapping fringes formed by the grating have optical magnification and error averaging effects, the measurement accuracy can be improved.

[0038] Example 3 The difference from the above embodiment is that a tension belt conveyor 6 is provided between the multi-channel single-piece separation system 3 and the multi-channel swing wheel sorter 5. Several KJT-15P magnetic proximity switches 8 are installed at the bottom of the tension belt conveyor 6, and these magnetic proximity switches 8 are connected to the controller. A third camera (not shown in the figure) is mounted on the tension belt conveyor 6, with its field of view centered at the center of the tension belt conveyor 6, and the third camera is connected to the controller.

[0039] The belt conveyor 6 increases the distance between packages by accelerating the transport process, facilitating sorting and preventing sorting chaos caused by packages being too close together. A third camera captures images of the packages on the belt conveyor 6, allowing for fine-tuning of transport speed and package spacing through image recognition. A magnetic proximity switch 8 senses magnetic force; therefore, it is triggered when a magnetic object is present in the package, alerting the user.

[0040] Example 4 The difference from the above embodiments is that, as Figure 4 As shown, one of the output ends of the multi-channel swing wheel sorter 5 is connected to the mail storage line 1.

[0041] Packages with overlapping parts cannot be packed. Therefore, one of the outputs of the multi-channel swing wheel sorter 5 can be connected back to the mail storage line 1, so that the overlapping packages can be sorted to the mail storage line 1 and the cycle can be restarted.

[0042] Example 5 The difference from the above embodiments is that the fully automatic package feeding machine 7 includes several short-distance belt conveyors 701, which are connected by transition sections, and each transition section is provided with a reflective strip 702.

[0043] The fully automatic package feeding machine 7 uses several short-distance belt conveyors 701 for feeding. The reflective strips 702 can mark the transition sections, making the transition sections more obvious under the reflective strips 702, which can effectively distinguish each conveying section and make it easier for users to judge the position of the package in the conveying process.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
