Description

Technical Field

[0002] With the rapid development of modern logistics, people have higher and higher requirements for logistics efficiency, more and more types of parcels are used for automated sorting, and the requirements for logistics automation equipment are also getting higher and higher. At present, there are many types of sorting machines, but different types of sorting machines have great differences in the types of items that can be sorted and the sorting efficiency. In modern logistics automated high-speed sorting equipment, common automatic sorting machines include circular cross-belt sorting machines and high-speed slider sorting machines. However, for large packaged items, the existing circular sorting machines cannot be sorted or the sorting efficiency is low, which has a great impact on the goods. Although the high-speed slider sorting machine can sort, it is inefficient, which greatly affects the work efficiency of item sorting and cannot meet people's requirements for fast logistics efficiency. In addition, for flip-type parcel sorting vehicles or robots, their driving speed is relatively low, and tracks need to be set up on the ground.

[0052] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and drawings therein are essentially for illustrative purposes rather than for limiting the present invention.

[0053] In the following description of different exemplary embodiments of the present invention, reference is made to the accompanying drawings, which form a part of the present invention and in which different exemplary structures, systems and steps that can implement various aspects of the present invention are shown by way of example. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps can be used, and structural and functional modifications can be made without departing from the scope of the present invention. Moreover, although the terms "upper end", "lower end", "between", "side", etc. may be used in this specification to describe different exemplary features and elements of the present invention, these terms are used herein only for convenience, such as according to the direction of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present invention.

[0054] See also Figure 1 , Figure 1 , a schematic diagram of the structure of a flipping device that can embody the principle of the present invention is representatively shown. In this exemplary embodiment, the flipping device proposed by the present invention is described by taking a flipping device used for tipping and sorting large goods in a sorting system as an example. It is easy for those skilled in the art to understand that in order to apply the flipping device to other occasions, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the flipping device proposed by the present invention.

[0055] like Figure 1As shown, in this embodiment, the flipping device proposed by the present invention mainly includes a transmission mechanism 100, a flipping mechanism 200, a flipping plate 300 and a supporting mechanism 400. Figures 2 to 7 , Figure 2 A right side view of a flip device that can embody the principle of the present invention is representatively shown; Figure 3 A right side view of another state of the flip device that can embody the principle of the present invention is representatively shown; Figure 4 A top view of a flip device that can embody the principles of the present invention is representatively shown in FIG.

Figure 6 A stereoscopic view of a flip device that can embody the principles of the present invention is representatively shown in FIG. Figure 7 Another stereoscopic view of the flip device that can embody the principle of the present invention is representatively shown in FIG.

[0056] like Figure 1 and Figure 5 As shown, in this embodiment, the transmission mechanism 100 mainly includes a fixing base 110 and a driving motor 120. Specifically, the fixing base 110 is fixed on a base, or can be directly fixed on the bottom surface of the application occasion. The driving motor 120 is installed on the fixing base 110 and has an output shaft, the output shaft extends from the driving motor 120 and a transmission gear 121 is sleeved on the extended end thereof, and the transmission gear 121 can rotate with the output shaft, thereby realizing the power output of the driving motor 120.

[0057] Furthermore, if Figure 5 As shown, in this embodiment, the output shaft actually extends from opposite sides of the drive motor 120, that is, the two extended ends of the output shaft extend in opposite directions respectively, and the two extended ends are respectively provided with transmission gears 121 that can rotate with the output shaft. Accordingly, the flipping device proposed in the present invention can realize transmission cooperation in the bilateral direction in this embodiment, making the flipping process more stable. Among them, the following description of this embodiment is explained by taking the design of bilateral transmission cooperation as an example, and the details can be referred to the following content.

[0058] like Figures 5 to 7As shown, in this embodiment, the flip mechanism 200 mainly includes a shell 210. Specifically, the shell 210 is arranged on the fixed seat 110, and roughly forms a structure covering the upper part of the fixed seat 110. Among them, based on the design of double-sided transmission matching, the shell 210 has a parallel and spaced arrangement, that is, two flip end plates 211 are respectively located on both sides of the drive motor 120, and the two flip end plates 211 are respectively arranged opposite to the two transmission gears 121 of the transmission mechanism 100. A rack track 2111 is provided on the inner side of each flip end plate 211 (the side facing the transmission gear 121 opposite thereto), and the transmission gear 121 is transmission-matched with the corresponding rack track 2111. In addition, the meaning of the above-mentioned "matching" at least includes the meshing of the gear and the rack and the guiding matching of the gear and the track. In addition, the transmission mechanism 100 can also provide partial load-bearing function during the flipping process. Therefore, the coordination between the rack rail 2111 and the transmission gear 121 is achieved by the lower end surface of the rack rail 2111 contacting the transmission gear 121, that is, the tooth structure of the rack rail 2111 is formed by protruding downward (towards the transmission gear 121).

[0059] Specifically, if Figure 5 As shown, in this embodiment, the transmission gear 121 has a gear portion 1211 and a guide protrusion 1212. The transmission gear 121 is a gear portion 1211 sleeved on the outer periphery of the protruding end of the output shaft and presents a gear structure, that is, the gear portion 1211 can also be regarded as a gear. The guide protrusion 1212 protrudes from the center of the gear portion 1211 toward the direction of the matching rack track 2111 and is generally cylindrical. Correspondingly, the rack track 2111 is generally a groove structure formed by a recessed inner side of the flip end plate 211, and the rack track 2111 has a groove bottom 21111 and two groove walls 21112 respectively located on both sides of the groove bottom, and at least one of the two groove walls 21112 (the groove wall 21112 located on the relatively outer side of the groove bottom 21111 is used in this embodiment) has a rack structure 21113. Accordingly, the meshing transmission between the transmission gear 121 and the rack rail 2111 is realized by the meshing of the gear portion 1211 and the rack structure 21113, and the guide protrusion 1212 extends into the groove structure for guiding cooperation, thereby realizing the guidance during the meshing transmission process between the transmission gear 121 and the rack rail 2111. Figure 5 As shown, in this embodiment, the rack rail 2111 generally has two arc segments 21114 and a straight segment 21115. Specifically, the openings of the two arc segments 21114 are arranged opposite to each other, and the straight segment 21115 is connected between the top ends of the two arc segments 21114 and is tangent to the two arc segments 21114 respectively. Accordingly, during the flipping process of the flipping device, through the cooperation of the rack rail 2111 and the transmission gear 121 in the above-mentioned path, the flipping process of the flipping mechanism 200 and the flipping plate 300 driven by it is an eccentric motion process. Further, as Figure 5 As shown, in this embodiment, the arc segment 21114 of the rack track 2111 can preferably be designed as a semicircular arc path.

[0060] Through the above design, the flipping device proposed by the present invention can drive the transmission gear 121 to rotate through the driving motor 120, and drive the flipping mechanism 200 and the flipping plate 300 to flip through the transmission cooperation between the transmission gear 121 and the rack track 2111, so as to flip the goods. In this process, the flipping path is the path corresponding to the shape of the rack track 2111. Accordingly, the present invention can achieve a larger torque output of the motor through the transmission of the transmission gear 121 and the rack track 2111, thereby increasing the applicable weight of the goods flipped by the flipping device and realizing the sorting of goods with larger size and weight. The present invention can also realize the flipping of the flipping device on both sides through the design of the rack track 21111 connected tangently between the two arc segments 21114 by the straight line segment 21115, thereby increasing the number of sorting ports and reducing the floor space of the equipment.

[0061] Furthermore, by adopting the transmission matching design of the transmission gear 121 and the rack track 2111, the flipping device proposed by the present invention can accurately locate the flipping angle of the flipping device by judging the number of teeth or the overall distance traveled by the rack track 2111 during the transmission process between the transmission gear 121 and the rack track 2111, thereby avoiding the occurrence of excessive flipping or incomplete flipping. The above-mentioned judgment function can be realized by sensing elements such as photoelectric sensors and distance sensors, and the sensing elements can be associated with the control system of the device, so that the control system can issue control instructions and the operator can observe in real time through the monitor.

[0062] In other embodiments, the flipping device proposed in the present invention may also adopt other designs, while retaining the function of flipping on at least one side. For example, when the flipping device is only for one-side transmission, the output shaft may extend from only one side of the driving motor 120, and the transmission gear 121 is provided on the extended end of the output shaft. Accordingly, the housing 210 may have only one flipping end plate 211, and the flipping end plate 211 is arranged opposite to the transmission gear 121 of the transmission mechanism 100. A rack track 2111 is provided on the inner side of the flipping end plate 211 (the side facing the transmission gear 121), and the transmission gear 121 is transmission-matched with the corresponding rack track 2111.

[0063] In addition, in order to realize double-sided transmission, the flipping device proposed in the present invention may also adopt other structures. For example, the transmission mechanism 100 may include two drive motors 120, and the output shafts of the two drive motors 120 extend in colinear and opposite directions, and the output shafts of the two drive motors 120 rotate synchronously. Accordingly, the housing 210 may have two flipping end plates 211 arranged in parallel and spaced apart, that is, two flipping end plates 211 located on both sides of the drive motor 120, each flipping end plate 211 is provided with a rack rail 2111 on the inner side, and the two rack rails 2111 are respectively matched with the two transmission gears 121, that is, the structure of the housing 210 at this time may be substantially the same as the structure of the housing 210 of the present embodiment.

[0064] like Figure 6 and Figure 7 As shown, in this embodiment, the fixing seat 110 is vertically provided with first limit guide grooves 111 on both sides of the two flip end plates 211. Correspondingly, a first limit guide shaft is provided at the middle position of the lower end of each flip end plate 211. One end of the first limit guide shaft is fixed to the flip end plate 211 and the other end is slidably matched to the first limit guide groove 111. Figure 2 and Figure 3 It can be seen that when the flip mechanism 200 flips relative to the fixed seat 110, the lower ends of the two flip end plates 211 are respectively connected to the two sides of the fixed seat 110 in a liftable and rotatable manner, so that the above structure can realize the limit and guide functions of the flip device during the flipping process. In addition, when the flip device adopts a single-side transmission, the above limit guide structure can also be designed accordingly, which will not be described in detail here.

[0065] It should be noted that, in this embodiment, the first position limiting guide shaft may include two parts, namely, a shaft member having a size smaller than or equal to the first position limiting guide groove 111 and a position limiting member having a size larger than the first position limiting guide groove 111. Specifically, one end of the shaft member is connected to the flip end plate 211, and the other end passes through the first position limiting guide groove 111, and the position limiting member is connected to the other end of the shaft member.

[0066] like Figure 1 and Figure 4 As shown, in this embodiment, the flip plate 300 is fixed to the top of the shell 210 to carry goods.

[0067] Furthermore, if Figure 1 and Figure 4 As shown, in this embodiment, the flip plate 300 can preferably be designed with two sides bent upward to form a bent portion 320, so as to provide a buffering effect for the goods to slide out when the flip plate 300 flips over and the goods slide out. Furthermore, based on the above design of the flip plate 300, the flip plate 300 is fixed to the housing 210 with the bottom of the main body sandwiched between the bent portions 320 on both sides.

[0068] like Figure 1 , Figure 6 and Figure 7 As shown, in this embodiment, the support mechanism 400 mainly includes a support seat 410 and a flip block 420. Specifically, the support seat 410 is fixed on a base or the ground, and is spaced apart from the fixed seat 110 in a horizontal direction perpendicular to the flip direction (i.e., the length direction of the flip plate 300), and a limiting wheel 411 is provided on the support seat 410. Among them, the flip block 420 is fixed to the bottom of the flip plate 300 and is located on one side of the support seat 410 (the side with the limiting wheel 411), and a limiting track 421 is provided on the side of the flip block 420 opposite to the limiting wheel 411, and the limiting track 421 corresponds to the shape of the rack track 2111, and the limiting wheel 411 is slidably matched with the limiting track 421. Accordingly, the support mechanism 400 can provide an auxiliary support function, and can also provide an auxiliary guiding function by designing the limiting rail 421 to correspond to the shape of the rack rail 2111. In particular, when the flipping device is used for flipping and sorting large-sized goods, that is, when the length of the flip plate 300 is large, the support mechanism 400 can cooperate with the transmission mechanism 100 and the flipping mechanism 200 to achieve stable bearing and flipping of the flip plate 300 and the goods.

[0069] It should be noted that, in this embodiment, the limiting wheel 411 is rotatably arranged on the support seat 410 by using a rotating shaft, and the limiting track 421 is provided on the flip block 420 in the form of a through groove. On this basis, the limiting wheel 411 and the limiting track 421 can achieve sliding cooperation through a cooperation structure similar to that of a train wheel and a rail. The above-mentioned design of the limiting wheel 411 can be understood as a variety of structures that can cooperate with the limiting track 421, such as rollers, rollers, sliders, etc., and is not limited to this embodiment.

[0070] Furthermore, if Figure 6 and Figure 7 As shown, in this embodiment, a second position limiting guide groove 412 is vertically opened on one side of the support seat 410 relative to the flip block 420. Correspondingly, a second position limiting guide shaft 422 is provided at the middle position of the lower end of the flip block 420. One end of the second position limiting guide shaft 422 is fixed to the flip block 420 and the other end is slidably matched with the second position limiting guide groove 412. Accordingly, when the flip mechanism 200 drives the flip plate 300 to flip, the flip block 420 flips along with the flip plate 300, and the lower end of the flip block 420 is liftable and rotatably connected to the support seat 410, so that the auxiliary position limiting and auxiliary guiding functions of the support mechanism 400 during the flipping process are realized through the above structure.

[0071] It should be noted that, in this embodiment, the second position-limiting guide shaft 422 may include two parts, namely, a shaft member having a size smaller than or equal to the second position-limiting guide groove 412 and a position-limiting member having a size larger than the second position-limiting guide groove 412. Specifically, one end of the shaft member is connected to the flip block 420, and the other end passes through the second position-limiting guide groove 412, and the position-limiting member is connected to the other end of the shaft member.

[0072] In other embodiments, the flipping device proposed in the present invention may not be provided with the above-mentioned support mechanism 400, or other designs may be used to replace the above-mentioned support mechanism 400 to provide the auxiliary support function. Furthermore, when the flipping device is used for flipping and sorting large-sized goods, that is, when the flipping plate 300 is relatively long, multiple groups of flipping mechanisms 200 and transmission mechanisms 100 may be arranged at intervals along the length direction of the flipping plate 300, and the driving motors 120 of the multiple transmission mechanisms 100 synchronously drive the flipping mechanisms 200, so as to realize the flipping function of large-sized goods.

[0073] It should be noted that the flipping device shown in the drawings and described in this specification is only one example of many flipping devices that can adopt the principles of the present invention. It should be clearly understood that the principles of the present invention are by no means limited to any details of the flipping device shown in the drawings or described in this specification or any parts of the flipping device.

[0074] To summarize, the flipping device provided by the present invention adopts the design of "a transmission gear is matched with a rack track, ... the flipping device drives the transmission gear to rotate through a driving motor, and the transmission cooperation between the transmission gear and the rack track drives the flipping mechanism and the flipping plate to flip, so as to flip the goods". The transmission of the transmission gear and the rack track can achieve a larger torque output of the motor, thereby increasing the applicable weight of the goods flipped by the flipping device and realizing the sorting of goods with larger size and weight.

[0075] Furthermore, the flipping device provided by the present invention adopts the design of "the rack track has two arc segments and one straight segment, the openings of the two arc segments are arranged opposite to each other, and the straight segment is connected between the top ends of the two arc segments and is tangent to the two arc segments respectively", which can enable the flipping device to flip on both sides, thereby increasing the number of sorting ports and reducing the floor space of the equipment.

[0076] In addition, the turning device provided by the present invention can also be installed on a ring sorting machine, so that multiple turning devices can be operated simultaneously to further improve the sorting efficiency.
