Description

Technical Field

[0001] This invention relates to the field of logistics sorting technology, and more specifically, to a ring conveyor device for logistics sorting. Background Technology

[0002] Modern production has entered an era of rapid development, and manual labor can no longer meet production needs. With the continuous increase in labor costs, how to shorten the cycle time, improve production efficiency, shorten the flow time between processes, and save labor costs is an important research direction. In the logistics industry, tens of thousands of packages are processed every day. Therefore, conveyor lines are important equipment. Circular conveyor equipment is a continuous conveyor line formed by connecting the beginning and end. Packages flow on the circular conveyor line for package classification and processing.

[0003] Although circular conveyor lines are currently in use, most of them only serve the function of parcel transfer. For example, Chinese invention patent (CN112173540A) discloses a circular conveyor device for logistics sorting, which still relies on manual sorting and does not make full use of the advantages of the circular conveyor device. Summary of the Invention

[0004] This invention provides a circular conveyor device capable of automatically sorting logistics packages.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A circular conveyor for logistics sorting includes a circular conveying mechanism and a rotary drive mechanism for driving the circular conveying mechanism to swing. A circular conveying space for material conveying is formed along the conveying direction of the circular conveying mechanism. The circular conveying space is divided into at least one conveying track and each conveying track is separated from each other. Each conveying track has an output port at one end. A discharge device for discharging material from the output port is provided at the position of each output port. The conveying track conveys the material to the discharge device and creates a compressive force between the material and the discharge device. The compressive force is the pressure between the material and the component in the discharge device for discharging the material from the output port.

[0007] In a preferred embodiment, the angle between the discharge direction of discharge port one and the direction of material conveying on the conveying track at discharge port one ranges from 45° to 135°.

[0008] In a preferred embodiment, the discharge device is discharge mechanism one or discharge mechanism two. The component of discharge mechanism one that discharges material from the outlet contacts the side wall of the material, and the component of discharge mechanism two that discharges material from the outlet contacts the upper wall of the material.

[0009] In a preferred embodiment, two conveying tracks are provided, and the output ports on the two conveying tracks are respectively discharge port one and discharge port two. Discharge mechanism one and discharge mechanism two are respectively located at the positions of discharge port one and discharge port two.

[0010] In a preferred embodiment, the discharge mechanism includes a mounting plate fixedly installed at the end of the conveying track. At least one vertically placed discharge conveying roller is installed below the mounting plate. A motor is fixedly installed on the mounting plate for driving the discharge conveying roller to rotate. The component for discharging material from the output port is the discharge conveying roller.

[0011] In a preferred embodiment, the discharge mechanism 2 includes a mounting plate 2 fixedly installed at the end of the conveying track. At least one horizontally placed discharge conveying roller 2 is installed below the mounting plate 2. A motor 3 for driving the discharge conveying roller 2 to rotate is fixedly connected to the mounting plate 2. The outer surface of the discharge conveying roller 2 is a conical surface. The material is conveyed from the smaller end of the discharge conveying roller 2 to the larger end. The component for outputting the material from the output port is the discharge conveying roller 2.

[0012] In a preferred embodiment, the annular conveying mechanism includes two drive wheels and a motor for driving the drive wheels to rotate. A drive belt is fitted and engaged on the outer side of the two drive wheels. The outer surface of the drive belt is fixedly connected with uniformly arranged fixing blocks, and a support plate is fixedly installed on each fixing block.

[0013] In a preferred embodiment, the device further includes a baffle, which includes an outer baffle disposed on the outer side of the annular conveying space and an inner baffle disposed on the inner side of the annular conveying space. The outer baffle and the inner baffle are fixed to each other by a connecting plate. The outer baffle and the inner baffle surround both sides of the annular conveying space, and the output port is disposed on the outer baffle.

[0014] In a preferred embodiment, a feeding mechanism is provided above the annular conveying mechanism. The feeding mechanism includes a central rotating cylinder and conveying slides provided on both sides of the central rotating cylinder. The conveying slides are inclined downward and their lower ends are respectively connected to two conveying tracks. The annular conveying mechanism has a swing axis a. The axis of the central rotating cylinder is collinear with axis a. A lower pushing component and an upper pushing component are respectively provided at the upper ends of the two conveying slides.

[0015] In a preferred embodiment, the upper pushing assembly pushes the material into the conveying track where the discharge mechanism is located. The upper pushing assembly includes a pushing rod disposed at the upper end of the central rotating cylinder and a cylinder for driving the pushing rod to move in order to push the material.

[0016] The lower pusher assembly pushes the material into the conveying track where the discharge mechanism 2 is located. The lower pusher assembly includes a pusher plate set at the bottom of the inner side of the transfer cylinder and a cylinder 1 for driving the pusher plate to move to push the material. The side wall of the transfer cylinder is provided with a slide groove, and the pusher plate is located inside the slide groove.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. This invention uses a swing-type ring conveyor mechanism to quickly transport and classify logistics packages, separating packages of different sizes to minimize the risk of loss.

[0019] 2. When the logistics package is conveyed to the output port, the ring conveyor mechanism applies a forward force to the logistics package, causing the logistics package to stick tightly to the component in the discharge device used to output the material from the output port, generating a squeezing force. Through this squeezing force, the discharge device can easily convey the logistics package out of the output port.

[0020] 3. The rotary drive mechanism can drive the ring conveyor mechanism to swing, so that the output port can face different positions, thereby achieving the purpose of sorting logistics packages to different positions.

[0021] 4. By setting up discharge mechanism one and discharge mechanism two, and through different structural forms, they can generate extrusion force with the side walls or top walls of different types of logistics packages, thereby achieving the purpose of outputting or discharging logistics packages. During the swinging process, logistics packages are output to different sorting points to achieve the purpose of automatic sorting.

[0022] 5. The feeding mechanism can classify the incoming logistics packages and transport them to the corresponding conveyor tracks of the discharging mechanism 1 and discharging mechanism 2, so that the discharging mechanism 1 and discharging mechanism 2 can carry out conveying and sorting operations.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Refer to the instruction manual appendix Figures 1-7 A circular conveying device for logistics sorting includes a circular conveying mechanism 2 and a rotary drive mechanism 1 for driving the circular conveying mechanism 2 to swing. A circular conveying space 4 for material conveying is formed along the conveying direction of the circular conveying mechanism 2. The circular conveying space 4 is divided into at least one conveying track 40 and each conveying track 40 is spaced apart from each other. Each conveying track 40 has an output port at one end. A discharge device for discharging material from the output port is provided at the position of each output port. The conveying track 40 conveys the material to the discharge device and creates a compressive force between the material and the discharge device. The compressive force is the pressure between the material and the component in the discharge device for discharging the material from the output port.

[0036] The logistics package is conveyed on the ring conveyor mechanism 2. When it is conveyed to the output port, the ring conveyor mechanism 2 applies a forward force to the logistics package, so that the logistics package is pressed tightly against the component in the discharge device used to output the material from the output port, that is, the above-mentioned extrusion force is generated. Through this extrusion force, the discharge device can easily convey the logistics package out of the output port. The ring conveyor mechanism 2 can be driven to swing by the rotation drive mechanism 1, so that the output port can face different positions, thereby achieving the purpose of sorting the logistics package to different positions.

[0037] The rotary drive mechanism 1 described above can take many forms, such as a turntable drive. In this embodiment, for example... Figure 1 and Figure 2 As shown, the rotary drive mechanism 1 includes an annular drive guide rail 11 and a frame 12. The annular drive guide rail 11 has multiple sliders, and the frame 12 is mounted on the sliders. The rotary drive mechanism 1 also includes a transmission chain, a motor, positioning accessories, etc. When the rotary drive mechanism 1 drives the annular conveyor mechanism 2 to swing, it achieves this by sliding the sliders on the annular drive guide rail 11.

[0038] The aforementioned annular conveyor mechanism 2 can be circular or, as shown above, [the following is a list of shapes / forms]. Figure 1 The shape of the double-round-head flat key shown is specifically referred to in this embodiment. Figure 2 and Figure 3 As shown, the annular conveyor mechanism 2 includes two drive wheels 21 and a motor 22 for driving the drive wheels 21 to rotate. A drive belt 23 is fitted and engaged on the outer sides of the two drive wheels 21. Evenly distributed fixing blocks 24 are fixedly connected to the circumferential outer surface of the drive belt 23, and a pallet 25 is fixedly mounted on each fixing block 24. The pallets 25 can be detachably fixed to the fixing blocks 24 for easy installation, disassembly, and transportation. The drive belt 23 can be a belt or a chain. When conveying packages, the annular conveyor mechanism 2 drives the drive wheels 21 to rotate via the motor 22, thereby rotating the drive belt 23. The packages are then placed on the pallets 25 for conveying.

[0039] In this embodiment, to ensure that the logistics packages are stably transported on the pallet 25 without falling off, such as Figure 1 and Figure 7 As shown, a baffle frame 3 is provided, which includes an outer baffle 31 disposed on the outer side of the annular conveying space 4 and an inner baffle 32 disposed on the inner side of the annular conveying space 4. The outer baffle 31 and the inner baffle 32 are fixed to each other by a connecting plate 33. The outer baffle 31 and the inner baffle 32 surround both sides of the annular conveying space 4, and the output port is disposed on the outer baffle 31. The baffle frame 3 is fixed to the frame 12 as a whole.

[0040] In this embodiment, as Figure 1and Figures 3-6 As shown, the discharge device is either discharge mechanism 5 or discharge mechanism 6. The component of discharge mechanism 5 that discharges material from the outlet contacts the side wall of the material, while the component of discharge mechanism 6 that discharges material from the outlet contacts the top wall of the material. In this embodiment, logistics packages are divided into two types: the first type includes logistics packages packaged in cartons and larger packages that are not packaged in cartons; the second type includes bagged and boxed logistics packages, i.e., thinner packages. The first type of logistics package is suitable for discharge using discharge mechanism 5, and the second type is suitable for discharge using discharge mechanism 6. If only one type of package needs to be processed, only the corresponding discharge mechanism 5 or discharge mechanism 6 needs to be used. Of course, depending on the number of outlets, discharge mechanism 5 and discharge mechanism 6, and their quantities, can be reasonably selected.

[0041] In this embodiment, as Figure 3 and Figure 4 As shown, there are two conveyor tracks 40, with output ports 41 and 42 respectively. Discharge mechanisms 5 and 6 are respectively located at discharge ports 41 and 42. Discharge ports 41 and 42 are used to process the first type of logistics parcel and the second type of logistics parcel, respectively.

[0042] Specifically, such as Figure 3 and Figure 5 As shown, the discharge mechanism 5 includes a mounting plate 51 fixedly installed at the end of the conveying track 40. At least one vertically placed discharge conveying roller 52 is installed below the mounting plate 51. A motor 53 for driving the discharge conveying roller 52 to rotate is fixedly installed on the mounting plate 51. The component for discharging material from the output port is the discharge conveying roller 52. Figure 5 As shown, there are two discharge conveyor rollers 52, which are driven by a belt and pulley. When the logistics package is output, the two discharge conveyor rollers 52 are rotated by the motor 53. The first type of logistics package is closely connected to the discharge conveyor rollers 52 under the conveying of the annular conveyor mechanism 2, so that the logistics package can be quickly output from the discharge port 41 through the discharge conveyor rollers 52.

[0043] Specifically, such as Figure 4 and Figure 6As shown, the discharge mechanism 26 includes a mounting plate 261 fixedly installed at the end of the conveying track 40. At least one horizontally placed discharge conveying roller 262 is installed below the mounting plate 261. A motor 363 for driving the discharge conveying roller 262 to rotate is fixedly connected to the mounting plate 261. The outer surface of the discharge conveying roller 262 is conical. Material is conveyed from the smaller end to the larger end of the discharge conveying roller 262. The component used to output material from the output port is the discharge conveying roller 262. Figure 6 As shown, there are three discharge conveyor rollers 62, which are driven by belts and pulleys to the motor 63. When outputting the logistics package, the motor 63 drives the discharge conveyor rollers 62 to rotate. The second type of logistics package enters the bottom of the discharge conveyor rollers 62 under the conveying of the annular conveyor mechanism 2. Since the outer surface of the discharge conveyor rollers 62 is a conical surface, the squeezing force between the logistics package and the discharge conveyor rollers 62 increases. Thus, under the rotation of the discharge conveyor rollers 62, the logistics package can be quickly output from the discharge port 42.

[0044] In this embodiment, the angle between the discharge direction of the discharge port 41 and the material conveying direction of the conveying track 40 at the discharge port 41 is in the range of 45°-135°. Figure 1 As shown, the angle is preferably 90°. It should be noted that the output direction of the discharge mechanism 5 or the discharge mechanism 6 should be consistent with the outlet direction of the discharge port 41 or the discharge port 42 to prevent the logistics package from being blocked.

[0045] In this embodiment, the specific implementation scenario is as follows: During the sorting and conveying of logistics, the first type of logistics package is placed inside the conveyor track 40 corresponding to the discharge port 41, and the second type of logistics package is placed inside the conveyor track 40 corresponding to the discharge port 42. The packages are continuously conveyed by the annular conveyor mechanism 2. The first type of logistics package is conveyed by the annular conveyor mechanism 2 to the position of the discharge mechanism 5, where its sidewall exerts pressure against the discharge conveyor roller 52. The rotation of the discharge conveyor roller 52 allows the logistics package to be conveyed out from the discharge port 41. The second type of logistics package is conveyed by the annular conveyor mechanism 2 to the position of the discharge mechanism 6, where its upper wall exerts pressure against the outer surface of the discharge conveyor roller 62. The rotation of the discharge conveyor roller 62 allows the logistics package to be conveyed out from the discharge port 42. During the above-mentioned process of conveying logistics packages, the rotary drive mechanism 1 can drive the ring conveyor mechanism 2 and the baffle 3 to swing together, so that the orientation of the first discharge port 41 and the second discharge port 42 can be changed. Multiple logistics package sorting points can be set at the front end of the first discharge port 41 and the second discharge port 42, so that during the swinging process, the logistics packages can be output to the corresponding sorting point positions to achieve the purpose of sorting.

[0046] Example 2

[0047] Refer to the instruction manual appendix Figures 1-8 Based on Embodiment 1, a feeding mechanism 7 is provided above the annular conveying mechanism 2. The feeding mechanism 7 includes a transfer cylinder 71 and conveying slides 711 provided on both sides of the transfer cylinder 71. The conveying slides 711 are inclined downward and their lower ends are respectively connected to two conveying tracks 40. The annular conveying mechanism 2 has a swing axis a. The axis of the transfer cylinder 71 is collinear with axis a. The upper ends of the two conveying slides 711 are respectively provided with a lower pusher assembly 72 and an upper pusher assembly 73. The bottom end of the conveying slide 711 is fixedly connected to the upper end of the inner baffle 32. Therefore, the feeding mechanism 7 swings together with the annular conveying mechanism 2 and the baffle 3. Since the axis of the transfer cylinder 71 is collinear with axis a, the position of the transfer cylinder 71 remains unchanged during the swinging process.

[0048] Specifically, such as Figure 8 As shown, the upper pushing assembly 73 pushes the material into the conveying track 40 where the discharge mechanism 5 is located. The upper pushing assembly 73 includes a pushing rod 732 set at the upper end of the transfer cylinder 71 and a cylinder 731 for driving the pushing rod 732 to move to push the material.

[0049] Specifically, such as Figure 8 As shown, the lower pusher assembly 72 pushes the material into the conveying track 40 where the discharge mechanism 2 6 is located. The lower pusher assembly 72 includes a pusher plate 721 disposed at the bottom of the inner side of the transfer cylinder 71 and a cylinder 722 for driving the pusher plate 721 to move to push the material. The side wall of the transfer cylinder 71 is provided with a slide groove 712, and the pusher plate 721 is located inside the slide groove 712.

[0050] Specifically, such as Figure 1 As shown, a conveyor belt 8 is provided on one side above the transfer cylinder 71 for conveying logistics packages into the interior of the transfer cylinder 71.

[0051] In this embodiment, the specific implementation scenario is as follows: Logistics packages are conveyed into the transfer drum 71 via the conveyor belt 8. If it is a first type of logistics package, the pusher rod 732, driven by cylinder 2 731, pushes it from the conveying chute 711 to the conveying track 40 where the discharge port 1 is located. If it is a second type of logistics package, the pusher plate 721, driven by cylinder 1 722, pushes it from the conveying chute 711 to the conveying track 40 where the discharge port 2 is located. Figure 8 As shown, the side of the pusher plate 721 near the upper pusher assembly 73 is set as an inclined surface to facilitate the passage of the first type of logistics package through the inclined surface.

[0052] A volume measurement DWS device can be installed at the location of the material conveying chute 711. The volume measurement DWS device uses dual 4-hole depth-square sensors to perform 3D visual measurement of the logistics package, quickly collect the size and volume of the logistics package, and compare it with preset parameters to determine whether the lower push component 72 or the upper push component 73 is in operation.

[0053] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
