Description

Technical Field

[0001] The present invention generally relates to the field of logistics, specifically to logistics sorting, and more particularly to a transmission device and a transmission method. Background Art

[0002] With the vigorous development of the logistics industry, the demand for sorting equipment for objects is increasing, and automated sorting technology is gaining more and more attention. Among the common sorting equipment currently, most of the transmission uses regular belts, rollers, etc. for transmission: the entire belt transmission has requirements and restrictions on space and layout, and roller transmission is generally not suitable for soft packages and reports with uneven bottom surfaces. The transmission direction of traditional transmission mechanisms is generally linear. If the direction needs to be changed, a splitter needs to be added (such as lifting and transplanting, etc.), which cannot achieve multi-directional transmission and sorting. Summary of the invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a transmission device and a transmission method capable of realizing multi-directional transmission.

[0004] In a first aspect, the transmission device of the present invention comprises at least three transmission modules, each of which is provided with two opposite transmission directions, the straight lines where the transmission directions of the transmission modules are located intersect, and any transmission module is arranged on the transmission path of other transmission modules.

[0005] In a second aspect, the transmission method of the present invention utilizes a transmission device to transmit packages, and sets the transmission direction of the transmission module through which the package flows out of the transmission device to point from the inside of the transmission device to the outside of the transmission device, and sets the transmission direction of other transmission modules to point from the outside of the transmission device to the inside of the transmission device.

[0006] According to the technical solution provided in the embodiment of the present application, by setting up multiple transmission modules, each transmission module is provided with two opposite transmission directions, and the straight lines where the transmission directions of each transmission module are located intersect. When a package enters the transmission device from any transmission module, the transmission direction of each transmission module is controlled according to the flow direction of the package, so that the package can flow out of any transmission module, completing the package transmission to achieve multi-directional transmission. The structure is simple, and can solve the problem that the existing transmission mechanism needs to add a splitter to achieve multi-directional transmission. BRIEF DESCRIPTION OF THE DRAWINGS

It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] One embodiment of the present invention is, please refer to Figures 1 to 3 The transmission device of the present invention includes at least three transmission modules 10, each transmission module 10 is provided with two opposite transmission directions, the straight lines where the transmission directions of each transmission module 10 are located intersect, and any transmission module 10 is arranged on the transmission path of other transmission modules 10.

[0017] In an embodiment of the present invention, at least three transmission modules are included, each of which is provided with two opposite transmission directions, and the straight lines where the transmission directions of the transmission modules are located intersect with each other. The package can flow into the transmission device from any transmission module, and can also flow out of the transmission device from any transmission module. The movements of the transmission modules are independent of each other. When the package moves between the transmission modules, each transmission module applies forces in different directions to the package, so that the package can move toward one of the transmission modules, and the transmission module sends the package out of the transmission device. Multi-directional transmission of the package can be achieved without adding a splitter. The structure is simple and easy to manufacture and install. At the same time, multiple transmission devices can be spliced ​​together to form a complete transmission surface to transfer packages. The number of transmission devices can be set according to actual conditions, thereby expanding the flexibility of the transmission device.

[0018] Furthermore, four transmission modules 10 are included, and the transmission directions of any two adjacent transmission modules 10 are perpendicular to each other.

[0019] In an embodiment of the present invention, four transmission modules are provided, the transmission surface of each transmission module is a triangle, and the four transmission modules constitute a rectangular or square transmission surface. The package can flow into the middle of the transmission device from any transmission module, and then flow out of the transmission device from other transmission modules. During the package transmission process, all transmission modules are in action.

[0020] refer to Figure 4 , the package moves from A to B. Specifically, the package moves from A to the middle of the transmission device. Under the joint action of the transmission modules at A, B, C and D, the package can only flow out from the transmission module at B. At this time, the transmission direction of the transmission module at A is from the outside of the transmission device to the inside of the transmission device, the transmission direction of the transmission module at B is from the inside of the transmission device to the outside of the transmission device, the transmission direction of the transmission module at C is from the outside of the transmission device to the inside of the transmission device, and the transmission direction of the transmission module at D is from the outside of the transmission device to the inside of the transmission device.

[0021] refer to Figure 5 , the package moves from A to C. Specifically, the package moves from A to the middle of the transmission device. Under the joint action of the transmission modules at A, B, C and D, the package can only flow out from the transmission module at C. At this time, the transmission direction of the transmission module at A is from the outside of the transmission device to the inside of the transmission device, the transmission direction of the transmission module at B is from the outside of the transmission device to the inside of the transmission device, the transmission direction of the transmission module at C is from the inside of the transmission device to the outside of the transmission device, and the transmission direction of the transmission module at D is from the outside of the transmission device to the inside of the transmission device.

[0022] refer to Figure 6 , the package moves from A to D. Specifically, the package moves from A to the middle of the transmission device. Under the joint action of the transmission modules at A, B, C and D, the package can only flow out from the transmission module at D. At this time, the transmission direction of the transmission module at A is from the outside of the transmission device to the inside of the transmission device, the transmission direction of the transmission module at B is from the outside of the transmission device to the inside of the transmission device, the transmission direction of the transmission module at C is from the outside of the transmission device to the inside of the transmission device, and the transmission direction of the transmission module at D is from the inside of the transmission device to the outside of the transmission device.

[0023] When a package flows out of the transmission device from any transmission module, only the transmission direction of this transmission module is from the inside of the transmission device to the outside of the transmission device, and the transmission directions of other transmission modules are all from the outside of the transmission device to the inside of the transmission device. This can prevent the package from flowing out of the transmission device from other transmission modules, thereby improving the accuracy of the package flow direction.

[0024] Furthermore, any two opposite transmission modules 10 are arranged as an axisymmetric structure.

[0025] In an embodiment of the present invention, any two relative transmission modules are arranged as an axially symmetrical structure, which facilitates the processing and manufacturing of the transmission device and reduces the subsequent maintenance cost. At the same time, it makes the package more evenly stressed during the transmission process, avoids damage to the package during the transmission process, and improves the reliability of the transmission device.

[0026] Furthermore, any transmission module 10 is provided with a plurality of transmission belts 11 in parallel, and the transmission direction of the transmission belts 11 is the transmission direction of the transmission module 10 .

[0027] In the embodiment of the present invention, any transmission module is provided with a plurality of transmission belts in parallel, the transmission direction of the transmission belts is the transmission direction of the transmission module, the widths of the plurality of transmission belts are equal, the lengths are not equal, and the distances between any two adjacent transmission belts are equal, so that the package is subjected to more uniform force during the transmission process, and the package is prevented from being damaged during the transmission process, thereby improving the reliability of the transmission device. The transmission belt has a large transmission capacity, a simple structure, and good versatility, and can be suitable for soft packages or packages with uneven bottom surfaces, which is convenient for later maintenance, and the spatial structure layout is free, which can effectively utilize the space and improve the transmission efficiency.

[0028] Furthermore, a plurality of transmission belts 11 in any transmission module 10 are driven synchronously.

[0029] In an embodiment of the present invention, a plurality of transmission belts are driven synchronously, that is, the transmission belts in a single transmission module are all driven synchronously, which facilitates the transmission of packages by the single transmission module and improves the transmission efficiency and reliability of the transmission module.

[0030] Furthermore, a driving device 40 is included, and the transmission belt 11 is tensioned through the driving pulley 12 and the driven pulley 13. The driving device 40 drives the driving pulley 12 in any transmission module 10 to rotate synchronously.

[0031] In the embodiments of the present invention, the driving device can be, but is not limited to, a motor. Of course, the driving pulley can also be set as an electric roller to directly drive the transmission belt for synchronous transmission. The transmission belt is tensioned by the driving pulley and the driven pulley. The distance between the driving pulley and the driven pulley can be adjusted. By replacing transmission belts of different lengths, the distance between the driving pulley and the driven pulley is adjusted, and the length of the transmission module is adjusted. By increasing or decreasing the number of transmission belts, the width of the transmission module is adjusted to adapt to different scenarios, thereby improving the applicability of the transmission device. The driving device drives the driving pulley to rotate synchronously, and can, but is not limited to, make multiple driving pulleys rotate synchronously through synchronous transmission mechanisms such as sprocket chain transmission mechanisms, belt pulley transmission mechanisms, and gear transmission mechanisms.

[0032] Furthermore, the driving pulley 12 is arranged on a side of the transmission belt 11 away from the other transmission module 10 , and the driven pulley 13 is arranged on a side of the transmission belt 11 close to the other transmission module 10 .

[0033] In an embodiment of the present invention, a driving pulley is arranged on a side of the transmission belt away from another transmission module, and the driving pulley of a single transmission module can be set to the same driving pulley, which is convenient for adjustment and installation of the transmission module. At the same time, the driving device only needs to drive the driving pulley to rotate, which can improve the transmission efficiency.

[0034] Furthermore, the length of the transmission belt 11 close to the middle of the transmission module 10 is greater than the length of the transmission belt 11 far from the middle of the transmission module 10 .

[0035] In an embodiment of the present invention, the length of the transmission belt near the middle of the transmission module is greater than the length of the transmission belt far from the middle of the transmission module, so that the structure of each transmission module of the transmission device is more compact, the spatial structure layout of the transmission device is free, the space can be effectively utilized, and the transmission efficiency is improved.

[0036] Furthermore, universal balls 20 are arranged between the transmission modules 10 , and the universal balls 20 are arranged on the transmission paths of the transmission modules 10 .

[0037] In an embodiment of the present invention, universal ball transfers are arranged between the transmission modules. The universal ball transfers are arranged on the transmission path of the transmission modules. The gaps between the transmission modules are smoothly transitioned by the universal ball transfers, so that the transmission device can transmit packages more smoothly, reducing the wear between the packages and the transmission device, and improving the service life of the transmission device and the transmission reliability.

[0038] The universal ball transfer roller can be arranged between adjacent transmission belts of different transmission modules, and the universal ball transfer roller is arranged on the transmission path of the transmission belt. The transmission surface of the universal ball transfer roller and the transmission surface of the transmission belt are coplanar. When the package leaves one transmission belt and goes to another transmission belt, the universal ball transfer roller can make a smooth transition, thereby reducing the wear of the transmission device on the package and improving the service life of the transmission device and the transmission reliability.

[0039] Furthermore, a detection module 30 is included, and the detection module 30 is used to detect whether a package passes by a side of any transmission module 10 away from another transmission module 10.

[0040] In an embodiment of the present invention, a detection module is included. The detection module is used to detect whether a package passes by the side of any transmission module away from another transmission module. When the transmission direction of the transmission module is from the outside of the transmission device to the inside of the transmission device, the detection module is set at the entrance of the transmission module. The detection module can detect from which transmission module the package enters the transmission device and from which transmission module the package flows out of the transmission device, so as to monitor the flow direction of the package and track the package later.

[0041] Another embodiment of the present invention is, with reference to Figure 4-6 The transmission method of the present invention utilizes a transmission device to transmit packages, and sets the transmission direction of the transmission module 10 through which the package flows out of the transmission device to point from the inside of the transmission device to the outside of the transmission device, and sets the transmission direction of other transmission modules 10 to point from the outside of the transmission device to the inside of the transmission device.
