Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to a sorting device for goods sorting. Background Art

[0002] With the development of the logistics industry, sorting equipment is becoming increasingly automated. Sorting goods typically involves scanning, identifying, or diverting them, requiring a positioning device to center or sideways transport the goods.

[0003] Whole-position devices such as pendulum wheel sorters are important components of automatic sorting systems. They are mainly composed of conveyor rollers, synchronous steering controllers, transmission devices, frames, etc. During operation, according to the instructions and information identification issued by the management system, the steering controller changes the running direction of the conveyor rollers, which can realize sorting of items on the left and right sides, center scanning, etc., and then transfer the items to the diverter conveyor. However, existing pendulum wheel sorters used in logistics sorting scenarios generally use a transmission structure with multiple sets of electric connecting rods to achieve the swing angle control of the transmission wheel. A large amount of mechanical friction is generated during the transmission process. The mechanical connecting rods will wear out after long-term use, and abnormal noises will also be generated. At the same time, the transmission wheels mostly use O-belts for horizontal movement. A large number of O-belts are required, which are severely worn after long-term operation and need to be regularly inspected and replaced, resulting in increased maintenance costs. Utility Model Content

[0004] The utility model provides a sorting device for cargo sorting, which solves the technical problems of the existing sorting device, such as the transmission structure of multiple sets of electric connecting rods to realize the swing angle control of the transmission wheel, severe mechanical friction, and the transmission wheel mostly using O-belts for horizontal movement, which requires regular inspection and replacement, resulting in increased maintenance costs.

[0005] The utility model can be realized through the following technical solutions:

[0006] A device for sorting goods includes a guide mechanism, wherein the guide mechanism includes a plurality of Mecanum wheels arranged in a matrix, and the Mecanum wheels in the same row are arranged on the same rotating shaft.

[0007] The Mecanum wheels in odd-numbered rows are staggered with those in even-numbered rows, and the axial center lines of their rotating rollers are perpendicular to each other.

[0008] The ends of the odd-numbered rows of rotating shafts and the ends of the even-numbered rows of rotating shafts on the same side are connected to the corresponding drivers through their own orthogonal transmission mechanisms.

[0009] The orthogonal transmission mechanism adopts non-contact transmission to convert the vertical rotation generated by the driver into horizontal rotation, so as to drive the Mecanum wheels on the rotating shafts in odd rows or even rows to rotate synchronously.

[0010] Furthermore, the orthogonal transmission mechanism includes a transmission shaft connected to the output shaft of the driver, and a plurality of first hysteresis couplings are evenly spaced on the transmission shaft, a second hysteresis coupling is arranged directly above each of the first hysteresis couplings, and each of the second hysteresis couplings is coaxially connected to the end of the corresponding rotating shaft.

[0011] Further, the second hysteresis couplings in the odd-numbered rows are located outside the second hysteresis couplings in the even-numbered rows.

[0012] Furthermore, the driver adopts an electric motor, whose output shaft is coaxially connected to the transmission shaft through a belt transmission mechanism.

[0013] Furthermore, the guide mechanism and the corresponding orthogonal transmission unit and driver together constitute a standard unit, and one or more guide mechanisms are evenly spaced along the axial direction of the rotating shaft in the standard unit. They can be detachably connected in series with each other through a parallel transmission mechanism. The parallel transmission mechanism is used to synchronously transmit the rotation of the rotating shaft in the current guide mechanism to the corresponding rotating shaft in the next guide mechanism.

[0014] Furthermore, the parallel transmission mechanism includes a plurality of hysteresis coupling pairs arranged in one-to-one correspondence with the rotating shafts of the guide mechanisms including the standard units, and each of the hysteresis coupling pairs includes two hysteresis couplings, which are arranged in parallel, one of which is coaxially connected to the end of the rotating shaft in the current guide mechanism, and the other is coaxially connected to the end of the corresponding rotating shaft in the next guide mechanism.

[0015] Furthermore, the orthogonal transmission mechanism is located at one end of the rotating shaft of the standard unit, and the parallel transmission mechanism connected thereto is located at the other end of the rotating shaft of the standard unit.

[0016] Furthermore, the guide mechanism and the corresponding orthogonal transmission unit and driver together constitute a standard unit, and the two standard units are arranged in mirror symmetry.

[0017] The beneficial technical effects of the utility model are:

[0018] 1. The orthogonal transmission mechanism is constructed with a hysteresis coupling, replacing the traditional belt drive with a non-contact transmission. The Mecanum wheel on the drive shaft rotates synchronously to achieve the orientation adjustment of the goods on the guide mechanism. This can effectively reduce mechanical wear and maintenance costs, while effectively extending the service life of the entire device and making it more practical.

[0019] 2. The parallel transmission mechanism constructed with the hysteresis coupling realizes the extended connection of multiple guide mechanisms and standard units, and they can be freely disassembled from each other, which is suitable for sorting goods of different sizes, greatly expanding the scope of application of the whole-position device of the utility model;

[0020] 3. By independently controlling the Mecanum wheels of group A and group B to rotate forward, reverse, and stop, the angle of the goods on the guide mechanism can be adjusted between 0 degrees and 180 degrees. The adjustment range is wider and the flexibility is better, which is more conducive to the flow of goods to the next workstation. At the same time, the two standard units can be used in combination to center the goods, which is conducive to the scanning operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0027] like Figure 1 and 2As shown, the utility model provides a positioning device for cargo sorting, including a guide mechanism, which includes a plurality of Mecanum wheels 1 arranged in a matrix. The Mecanum wheels 1 in the same row are arranged on the same rotating shaft, and the Mecanum wheels 1 in the odd rows are staggered with the Mecanum wheels 1 in the even rows. The axial centerlines of their rotating rollers are perpendicular to each other, for example, at 45 degrees and -45 degrees, respectively. The ends of the rotating shafts in the odd rows and the ends of the rotating shafts in the even rows on the same side are connected to corresponding drivers 3 through respective orthogonal transmission mechanisms 2. The orthogonal transmission mechanism 2 uses a non-contact transmission to convert the vertical rotation generated by the driver 3 into horizontal rotation, thereby driving the Mecanum wheels on the rotating shafts in the odd rows or the rotating shafts in the even rows to rotate synchronously. In this way, a non-contact transmission replaces the traditional belt drive, and the Mecanum wheels 1 on the drive shaft rotate synchronously to achieve the orientation adjustment of the goods on the guide mechanism, which can effectively reduce mechanical wear and maintenance costs, and at the same time effectively increase the service life of the entire device, making it more practical. In addition, the positioning device of the utility model includes two independent sets of drivers 3 and orthogonal transmission mechanisms 2, which respectively drive the Mecanum wheels 1 of the odd and even rows to rotate, making it easier to control the orientation adjustment of the goods and more flexible.

[0028] The details are as follows:

[0029] The hysteresis coupling utilizes the hysteresis effect to achieve the transmission of torque from the input shaft to the rotation of the output shaft through the mutual coupling of the magnetic fields of two magnetic cylinders. It is a non-contact coupling. In addition to having the function of buffering and absorbing vibrations of an elastic coupling, its greatest feature is that it breaks the structural form of traditional couplings and adopts a new magnetic coupling principle to achieve the transmission of force and torque between the driving shaft and the driven shaft without direct contact. Therefore, the utility model uses a hysteresis coupling to replace the traditional belt to construct an orthogonal transmission mechanism. The orthogonal transmission mechanism 2 includes a transmission shaft 21 connected to the output shaft of the driver 3. A plurality of first hysteresis couplings 22 are evenly spaced on the transmission shaft 21. A second hysteresis coupling 23 is provided directly above each first hysteresis coupling 22. Each second hysteresis coupling 23 is coaxially connected to the end of the corresponding rotating shaft.

[0030] Taking into account space utilization and avoiding interference, we stagger the two sets of orthogonal transmission mechanisms 2, one inside and one outside. For example, the second hysteresis coupling 23 in the odd rows is located on the outside of the second hysteresis coupling 23 in the even rows, and then one transmission shaft 22 is inside and one transmission shaft 22 is outside to achieve a staggered arrangement. At the same time, the driver 3 can use an electric motor, and its output shaft can be coaxially connected to the transmission shaft through a belt drive mechanism, so that the relative positions of the two motors can be further adjusted.

[0031] The Mecanum wheels 1 in the odd-numbered rows and the Mecanum wheels 1 in the even-numbered rows are group A and group B respectively. The corresponding drivers 3 and orthogonal transmission mechanisms 2 drive A and drive B respectively. When the positioning device of the present invention is used to adjust the position of the goods, the specific steps are as follows:

[0032]

[0033] By independently controlling the Mecanum wheels of group A and group B to rotate forward, reverse, and stop, the angle of the goods on the guide mechanism can be adjusted between 0 degrees and 180 degrees. This has a wider adjustment range, better flexibility, and is more conducive to the flow of goods to the next workstation.

[0034] Considering that QR code scanning operations are often required during cargo sorting, and the scanning actuators are mostly located in fixed positions such as the center of the transport channel, there will be a requirement for centering position adjustment of the cargo. At this time, we can combine the guide mechanism and the corresponding orthogonal transmission unit and driver to form a standard unit. By setting the two standard units in mirror symmetry to form a new type of positioning device, such as the orthogonal transmission mechanisms are both on the outside, and then performing 45-degree and 135-degree azimuth control on the two standard units respectively, centering adjustment can be achieved.

[0035] In addition, due to the different sizes of goods, we can design the standard unit into an expandable structure, that is, use the parallel transmission mechanism 4 to achieve the expansion of multiple guide mechanisms, such as Figure 3 As shown, one or more guide mechanisms can be evenly spaced along the axial direction of the standard unit rotating shaft. The specific number depends on the actual situation. They can be detachably connected in series with each other through a parallel transmission mechanism 4, wherein the orthogonal transmission mechanism 2 is at one end of the standard unit rotating shaft, and the parallel transmission mechanism 4 connected thereto is at the other end of the standard unit rotating shaft.

[0036] The parallel transmission mechanism 4 is used to synchronously transmit the rotation of the rotating shaft in the guide mechanism of the current guide mechanism, including the standard unit, to the corresponding rotating shaft in the next guide mechanism. It can adopt an implementation structure similar to that of an orthogonal transmission mechanism, including multiple hysteresis coupling pairs arranged in one-to-one correspondence with the rotating shafts of the guide mechanisms. Each hysteresis coupling pair includes two hysteresis couplings, respectively recorded as the third hysteresis coupling 41 and the fourth hysteresis coupling 42. They are arranged in parallel, one of them, such as the third hysteresis coupling 41, is coaxially connected to the end of the rotating shaft in the current guide mechanism, and the other, such as the fourth hysteresis coupling 42, is coaxially connected to the end of the corresponding rotating shaft in the next guide mechanism. Similarly, with the help of the hysteresis effect of the hysteresis coupling, the magnetic fields of the two magnetic cylinders are coupled with each other, so that the rotation of the rotating shaft of the current guide mechanism can be transmitted to the rotating shaft of the next guide mechanism. In this way, there is no need to make standard units of different sizes according to goods of different volumes, which can greatly improve the applicability of the whole-position device of the utility model and facilitate promotion and application.

[0037] In addition, according to actual requirements, we can also use the parallel transmission mechanism to splice and expand the standard unit along the axial direction of the transmission shaft, such as Figure 4 As shown, at this time, only one standard unit including an electric motor is required, which is used as a motorized standard unit, and the rest are non-motorized standard units. A third hysteresis coupling is set at the end of the transmission shaft away from the motor of the basic standard unit, and a fourth hysteresis coupling is set at one end of the transmission shaft of the non-motorized standard unit spliced ​​thereto, and so on, to complete the splicing and expansion.

[0038] Although specific embodiments of the present invention are described above, those skilled in the art should understand that these are merely examples and that various changes or modifications may be made to these embodiments without departing from the principles and essence of the present invention. Therefore, the scope of protection of the present invention is limited by the appended claims.
