[0010] Furthermore, when a plurality of recessed structures are provided on the screw-in base, the plurality of recessed structures are evenly distributed on the screw-in base at equal intervals; the inclination angle at the entrance of the propulsion gap matches the inclination angle relative to the slide rail when the carrier is suspended.

[0011] Furthermore, the propulsion structure is a spiral convex structure, and the gap between the convex structures is the propulsion gap; the position of the upper side of the rotating body is flush with the upper surface of the slide rail, so that the hanging hook of the carrier on the slide rail can be directly aligned with the entrance of the spiral propulsion gap.

[0012] Furthermore, the front end of the convex structure is provided with a accommodating tip to facilitate the hanging hook of the vehicle to smoothly enter the propulsion gap; the inclination angle at the entrance of the propulsion gap matches the inclination angle of the vehicle relative to the slide rail when hanging.

[0013] Furthermore, it also includes a mounting plate, wherein the mounting plate is located on both sides of the screw-in base and is respectively provided with a first positioning plate and a second positioning plate, which are respectively fixed to the slide rails on both sides of the screw-in base, and a carrier plate is provided on the lower extension plate of the first positioning plate away from the carrier boom, and the carrier plate is used to install and fix the drive motor.

[0014] Preferably, a sensor is further included. The sensor is fixedly connected to the slide rail through a connecting plate. The sensor can be located within the coverage area of the mounting plate and is used to detect the number of carriers released by the precession base for sorting.

[0015] Preferably, the outer surface of the conveyor belt is smooth.

Detailed implementation manners

[0036] In order to more clearly illustrate the technical solutions in the embodiments of the present invention and the prior art, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other implementation manners can also be obtained. In addition, the terms related to directions only represent the relative positional relationships between components, rather than absolute positional relationships.

[0037] In a hanging production line, it is a relatively conventional setting to make the carrier slide down by itself through an inclined slide rail. However, the carrier in this state cannot be effectively controlled, which is not conducive to subsequent operations such as rail combination, offloading, and transfer. Therefore, it is very necessary to set up a sorting device on the slide rail, which can release the carriers one by one and make them cooperate with the corresponding inbound and outbound structures to achieve various functional effects.

[0038] The embodiment of the present invention provides a screw propulsion type sorting device for sorting and releasing the carriers on the slide rail one by one. Please refer to Figures 1-11 , which mainly includes a screw-in base 2 embedded and rotatably connected along the direction of the slide rail 1, and a limit pressing plate 6 suspended directly above the slide rail 1. A spiral propulsion structure 22 is arranged on the outer surface of the screw-in base 2. A spiral propulsion gap is formed between the propulsion structure 22 and the screw-in base 2. The propulsion gap cooperates with the hanging hook of a single carrier to form a screw connection propulsion cooperation. The distance between the limit pressing plate 6 and the propulsion gap can only accommodate the running of the hanging hook of a single carrier. When the screw-in base 2 rotates, the carriers sliding down to the entrance of the propulsion gap can only be pushed and run downstream one by one through the propulsion cooperation with the propulsion structure 22, and are sorted and released from the exit of the propulsion gap.

[0039] The spiral propulsion structure 22 is arranged on the precession base 2, and a screw connection propulsion fit is formed between the hanging hook and the propulsion gap. That is, when the precession base 2 rotates, the propulsion structure 22 rotates synchronously. When the hanging hook is in the spiral propulsion gap, it will be gradually pushed downward until it falls off from the propulsion structure 22.

[0040] In this application, the precession base 2 mainly includes a rotating body 21, a propulsion structure 22, and a tooth pattern part 23. The tooth pattern part 23 and the propulsion structure 22 are both attached to the rotating body 21 and occupy different positions of the rotating body 21. The rotating body 21 is a cylindrical cavity. The propulsion structure 22 is arranged on the outer surface of the rotating body 21. The tooth pattern part 23 is opened at one end of the rotating body 21 to drive the rotating body 21 to rotate, so as to make the propulsion structure 22 rotate and realize the limit push of the vehicle.

[0041] In a specific embodiment, based on the running mode of the vehicle on the slide rail 1, the tooth pattern part 23 is opened at the downstream end of the rotating body 21. The tooth pattern part 23 is an annular structure and is coaxially arranged with the rotating body 21. The propulsion structure 22 is located in front of the tooth pattern part 23, and an annular drop step is arranged between the propulsion structure 22 and the tooth pattern part 23 to reserve enough space position for installing the transmission belt 5.

[0042] Due to the running effect of the transmission belt 5, when the vehicle slides down and is released from the propulsion structure 22, there is a frictional interference between the running transmission belt 5 and the hanging hook, which will cause phenomena such as jitter and derailment.

[0043] In the embodiment of this application, a shielding member 3 is provided to partially shield the tooth pattern part 23 located downstream. The shielding member 3 can be fixedly installed based on the downstream slide rail 1, and an arc-shaped shielding plate 31 is provided. Preferably, the circumferential ratio is one-half of a circle, that is, a semi-circular arc plate.

[0044] Specifically, please refer to Figure 4 、 Figure 8 、 Figure 11 ., the shielding member 3 includes a semi-circular arc-shaped shielding plate 31 coaxially flush with the rotating body 21 and a fixing member 32 connected and fixed to the slide rail 1. One end of the fixing member 32 is connected to the middle of the rear end face of the shielding plate 31, and the other end of the fixing member 32 smoothly extends to the groove of the slide rail 1 and is fixedly connected thereto. The shielding plate 31 is suspended and covers directly above the tooth pattern part 23 meshed with the transmission belt 5. The radius of the shielding plate 31 is the same as the radius of the rotating body 21.

[0045] Exemplarily, the fixing member 32 includes a vertical extension plate and a horizontal docking plate. The docking plate docks and fixes with the groove on the upper surface of the slide rail 1, and the extension plate is used to support the shielding plate 31 to the corresponding position. The shielding plate 31 is located at the drop step, and an annular groove can be opened at the cross-section of the drop step. The shielding plate 31 is provided with a second support member on the opposite side of the fixing member 32 and inserted into the annular groove (without affecting the normal rotation of the rotating body 21), and cooperates with the fixing member 32 to effectively support and position both sides of the shielding plate 31, so that the position of the shielding plate 31 is fixed and the distance from the transmission belt 5 remains stable without deformation due to long-term operation.

[0046] Based on the installation method of the shielding member 3, the tooth pattern portion 23 can also be arranged at the upstream end of the rotating body 21. At this time, the shielding member 3 can be synchronously installed on the upstream slide rail 1, which does not affect the normal operation of the vehicle on the slide rail 1.

[0047] Necessarily, when the shielding member 3 is located downstream, the shielding plate 31 should be at least flush with the drop step of the rotating body 21 when docking, and tend to reduce the docking height of the shielding plate 31 to avoid jamming and getting stuck when the vehicle slides down; when the shielding member 3 is located upstream, the shielding plate 31 should be at least flush with the drop step of the rotating body 21 when docking, and tend to increase the docking height of the shielding plate 31 to avoid jamming and getting stuck when the vehicle slides down.

[0048] In the embodiment of the present application, the screw-in base body 2 is embedded along the direction of the slide rail 1 and is installed and fixed to the truncated area of the slide rail 1 in a rotationally connected manner. Based on the basic structure of the screw-in base body 2, rotational connection can be achieved through the rotating body 21.

[0049] In a specific embodiment, the rotating body 21 can be provided with an axial rotating cavity so that it can be installed in parallel alignment with the direction of the slide rail 1. A fixed shaft 24 is arranged in the rotating cavity, and a rotational connection is formed between the fixed shaft 24 and the rotating body 21 through bearings 27. Two bearings 27 can be provided, as Figure 3 shown. Necessarily, an annular clamping groove can be opened in the rotating cavity, and a caliper can be provided to lock the bearing 27 in the rotating cavity to prevent the load from falling off.

[0050] When fixedly connecting with the slide rail 1, the first fixing portion 25 and the second fixing portion 26 can be respectively arranged at both ends of the fixed shaft 24 and fixedly installed with the upstream and downstream slide rails 1 respectively, so that the screw-in base body 2 can be axially embedded into the slide rail 1 and can form a rotational effect relative to the slide rail 1.

[0051] As an embodiment, the first fixing portion 25 is a detachable plate-like structure, such as Figure 3 、 Figure 9As shown in , it can be fixedly installed with the slider in the cavity of the slide rail 1 to facilitate assembly by screwing into the base 2. One end of the second fixing portion 26 can be directly fixed to the fixed shaft 24, and the other end is inserted into the inner cavity of the slide rail 1 and fixed by screws.

[0052] As another example, see Figure 10 The first fixing portion 25 is the same as the second fixing portion 26, and both are inserted into the cavity of the slide rail 1 for fixing; the fixing portion on one side can be set as a detachable structure to facilitate assembly.

[0053] It should be clear that after the screw-in base 2 is embedded in the slide rail 1, its axis is basically parallel to the direction of the slide rail 1, and the deviation angle between the rotation of the rotating body 21 and the slide rail 1 is almost non-existent, which will not affect the normal operation of the hanging vehicle.

[0054] In the embodiment of the present application, the toothed portion 23 establishes a transmission connection with the drive motor 4 through the transmission belt 5. The drive motor 4 is attached to the slide rail 1 for installation and is hung on the side away from the carrier suspension rod. A drive disk 41 is provided at the output end of the drive motor 4. The toothed portion 23 is provided with an annular tooth pattern, and a transmission belt 5 with a rack can be used to effectively transmit the driving force. The diameter of the drive disk 41 is larger than the diameter of the toothed portion 23, which can increase the rotation speed of the screw-in base 2.

[0055] In the present application, the screw-in base 2 is located in the truncation area of ​​the slide rail 1. In order to strengthen the connection strength there, a mounting plate 7 can be provided to be fixedly connected to the slide rails 1 on both sides of the screw-in base 2, and at the same time provide an installation position and support structure for the drive motor 4.

[0056] In a specific embodiment, the mounting plate 7 is provided with a first positioning plate 71 and a second positioning plate 72 on both sides of the screw-in base 2, respectively, and is fixedly connected to the slide rails 1 on both sides of the screw-in base 2, and a carrier plate 74 is provided on the side of the lower extension plate of the first positioning plate 71 away from the carrier boom, and the carrier plate 74 is used to install and fix the drive motor 4. The front end of the lower extension plate of the second positioning plate 72 can be provided with an outward-expanding catering plate to correct the posture of the carrier boom.

[0057] The sensor is also included. The sensor is fixedly connected to the slide rail 1 through the connecting plate 75. The sensor can be located in the coverage area of ​​the mounting plate 7. The sensor is used to detect the number of carriers released by the screwing-in base 2. In the embodiment of the present application, there is a certain distance between the connecting plate 75 and the second positioning plate 72. The connecting plate 75 and the first fixing portion 25 (plate structure) can be fixedly installed in a positional match to improve space utilization. The second fixing portion 26 and the first positioning plate 71 can also be fixedly installed in a positional match. Figure 7 as shown in .

[0058] It can be understood that the fixing effect between the mounting plate 7 and the sliding rail 1 has a longer span, which can effectively stabilize the connection stability at the truncated part of the sliding rail 1.

[0059] In the embodiment of the present application, a propulsion structure 22 is provided on the screwing base 2. The propulsion structure 22 is arranged relying on the rotating body 21 and can form a screw-type propulsion cooperation with the hanging hook. That is, the hanging hook is located within the propulsion structure 22. When the propulsion structure 22 rotates, the hanging hook runs along the spiral direction of the propulsion structure 22. In the present application, the main requirement is to run downstream.

[0060] As an embodiment, the propulsion structure 22 can be a spiral recessed structure. The entrance of the recessed structure is located at the front cross-section of the upstream of the rotating body 21, and the exit is located at the stepped cross-section of the downstream drop. At least one recessed structure is provided on the rotating body 21, and the recess is the propulsion gap, which forms a screw-type propulsion cooperation with the hanging hook.

[0061] To ensure that the hanging hook can enter the recessed structure one by one, the position on the upper side of the rotating body 21 should be higher than the upper surface of the sliding rail 1. After the recessed structure is provided, the entrance of the recessed structure is basically flush with the upper surface of the sliding rail 1, so that after a single hanging hook occupies the entrance, it can block the subsequent carriers; when the rotating body 21 rotates, the entrance position changes, and the rotating body 21 higher than the upper surface of the sliding rail 1 can also block the subsequent carriers from sliding down.

[0062] The inclination angle at the entrance of the propulsion gap matches the inclination angle of the carrier when it is hung relative to the sliding rail 1, so that when the entrance of the propulsion gap on the rotating body 21 rotates to the uppermost position, the hanging hook can be aligned and matched with it and enter the propulsion gap, and the hanging hook of the subsequent carrier is blocked.

[0063] It should be clear that when there is only one recessed structure, the rotating body 21 can only distribute and release one carrier per rotation. When there are multiple recessed structures on the screwing base 2, the rotating body 21 can distribute and release multiple carriers per rotation, and the number of distributions is the same as the number of recessed structures. The multiple recessed structures can be evenly distributed at equal intervals on the rotating body 21, so that the interval of distribution and release is stable and controllable.

[0064] As another embodiment, the propulsion structure 22 can be a spiral rib structure. There is a spiral gap in the rib structure spirally wound around the rotating body 21, and the width of the spiral gap only needs to match the hanging hook. The spiral gap between adjacent rib structures is the propulsion gap. The entrance of the propulsion gap is located at the front cross-section of the upstream of the rotating body 21, and the exit is located at the stepped cross-section of the downstream drop. Providing one rib structure on the rotating body 21 can form a screw-type propulsion cooperation with the hanging hook.

[0065] To ensure that the hanging hooks can enter the propulsion gap one by one, the upper side of the rotating body 21 should be flush with the upper surface of the slide rail 1, so that the propulsion gap rotated to the uppermost position is at the same height as the hanging hooks, which is conducive to the smooth entry of the hanging vehicle into the entrance of the propulsion gap; further, a catering tip is provided at the front end of the convex pattern structure, which is located at the entrance. While deflecting the hooks, it can also facilitate the smooth entry of the hanging hooks of the vehicle into the propulsion gap. Necessarily, the inclination angle at the entrance of the propulsion gap matches the inclination angle of the vehicle relative to the slide rail 1 during hanging.

[0066] It should be clear that for each rotation, only one vehicle enters the propulsion gap, that is, one vehicle can be deflected and released; subsequent vehicles are blocked by the convex pattern structure, and the next vehicle can enter only when the entrance rotates to the uppermost position again.

[0067] Based on the above two implementation manners of the propulsion structure 22, it can be seen that the deflection frequency of the convex pattern propulsion is relatively low, and the deflection frequency of the concave pattern propulsion can be set relatively high, and it can be adjusted according to the deflection frequency requirements in actual selection. In addition, the spiral length of the convex pattern structure is greater than the spiral length of the concave pattern structure, and the circumferential proportion of the concave pattern structure in the axial direction of the rotating body 21 can be less than 1.

[0068] It can be understood that the spiral propulsion gap in this application is similar in shape to a "spring", but there are openings at both ends to facilitate the entry and release of the hanging hooks; limited by the hanging structure of the vehicle, the propulsion gap blocks the normal sliding of the vehicle, but when the rotating body 21 rotates, the propulsion gap rotates synchronously, and the hanging hooks of the vehicle can slide down gradually along the spiral propulsion gap.

[0069] In this application, the above two implementation manners of the propulsion structure 22 are both used in cooperation with the limit pressing plate 6. The limit pressing plate 6 is suspended parallel to the upper part of the slide rail 1. The distance between the limit pressing plate 6 and the propulsion gap can accommodate the operation of a single hanging hook, so that each hanging hook entering the propulsion gap is one, without stacking; similarly, the distance between the limit pressing plate 6 and the slide rail 1 is the same. When multiple vehicles accumulate upstream of the screw-in base 2, the vehicles can be arranged in an orderly manner without stacking and without confusion during deflection.

[0070] Applicable to the concave texture structure, the limit pressing plate 6 is of a split structure; specifically including a pressing plate 61 and a fixing plate 62. The pressing plate 61 includes a vertical plate 611 and a pressing strip 612. The vertical plate 611 is fixedly connected to the upper end of the fixing plate 62. The pressing strip 612 is located at the lower end of the vertical plate 611 and is parallel to the upper surface of the slide rail 1. A catering part 613 is provided at the front end of the pressing plate 61 to facilitate the hanging hook of the carrier to enter the gap between the pressing plate 61 and the slide rail 1. The lower end of the fixing plate 62 extends to the lower side of the slide rail 1 and is fixedly connected. The fixing plate 62 is located on the side away from the carrier suspension rod. The pressing plate 61 is relatively long and can cover the upstream and downstream of the screwing-in base body 2.

[0071] Applicable to the convex texture structure, the limit pressing plate 6 is of an integral structure. Fixing holes are provided on the downward extension plate of the second positioning plate 72 to form a fixing area 73 for fixedly installing the integral limit pressing plate 6; the upper end of the limit pressing plate 6 is suspended on the upper surface of the slide rail 1, and the lower end of the limit pressing plate 6 extends to the fixing hole area of the downward extension plate for fixed installation; there is an expansion structure between the lower end of the limit pressing plate 6 and the slide rail 1, which does not affect the normal operation of the carrier. The limit pressing plate 6 is located on the side away from the carrier suspension rod. The suspension coverage range of the limit pressing plate 6 on the upper side of the slide rail 1 is relatively short and can be located at the upstream end of the screwing-in base body 2.

[0072] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
