Description

Technical Field

[0001] The utility model relates to the field of sorting devices, in particular to a roller centering machine and a sorting device. Background Art

[0002] Roller centering machines are commonly used conveying equipment in logistics sorting. Existing roller centering machines often use a friction drive module to drive two sets of conveyor rollers. For example, the utility model patent with authorization number CN220264245U exemplifies this design.

[0003] In order to facilitate assembly, the length of the two conveying rollers near the two ends needs to be set shorter and located at the top corners, and the friction drive module requires a certain width to drive. This makes it more difficult to avoid the structure when driving the rollers at both ends through the friction drive module, and also makes the structure of the friction drive module longer. Utility Model Content

[0004] The purpose of the present invention is to solve the above problems in the prior art and to provide a roller centering machine and a sorting device.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The roller centering machine includes a frame and an obliquely arranged conveying roller arranged on the frame. The conveying roller includes a first roller, a second roller and a group of third rollers arranged in sequence from the first end to the second end of the roller centering machine. The lengths of the first roller, the second roller and the third roller increase in sequence. The second roller and the third roller are in contact with the driving belt of the friction drive module and are driven to rotate by the friction drive module. The first roller and the second roller are connected by a transmission structure so that the two rotate synchronously.

[0007] Preferably, the roller is centered in the machine, and the transmission structure includes a transmission roller that is in contact with the first roller and the second roller and is located below them.

[0009] Preferably, the roller is centered in the machine, the support rod of the roller frame is connected to the frame so as to be movable up and down, and the roller frame is connected to an elastic member that allows the driving roller thereon to be tightly attached.

[0010] Preferably, the roller is centered in the machine, the drive belt is mounted on the drive roller, one end of the support shaft of the drive roller is rotatably connected to the module frame through a bearing, and the other end of the support shaft is connected to the reducer on the side of the module frame, and the reducer is connected to a motor that drives the support shaft to rotate.

[0011] Preferably, the roller is centered in the machine, and the reducer is connected to the side of the module frame through a flange.

[0012] Preferably, the roller is centered in the machine, and the frame includes a group of parallel and horizontally extending cross bars, the cross bars are provided with circular holes for connecting the friction drive module, and the horizontal bending part of the side plate of the module frame of the friction drive module is formed with a connecting hole corresponding to the circular hole, and a pad is also provided between the friction drive module and the cross bars.

[0013] Preferably, in the roller centering machine, an output end of the roller centering machine is provided with a lead-out roller located in a middle position and with an axis extending along the width direction of the roller centering machine.

[0015] A sorting device comprising any of the above-described roller centering machines.

[0016] The advantages of the technical solution of this utility model are mainly reflected in:

[0017] The present invention connects the first roller and the second roller by setting a transmission structure, so that the friction drive module does not need to drive the shortest first roller. Therefore, its length can be made shorter, which is beneficial to reducing the length of the friction belt of the friction drive module to ensure the stability of operation, and does not need to extend the friction drive module close to the cross bar at the end of the frame, which is beneficial to reducing the difficulty of structural avoidance and making it easier to assemble the equipment.

[0018] The transmission structure of the utility model is realized by using a transmission roller, and the transmission roller can maintain adaptive fit with the first roller and the second roller through the installation structure of the roller frame, thereby ensuring the reliability of the transmission.

[0019] The installation structure of the driving roller of the utility model can make full use of the bearing of the reducer, so that the module frame only needs to be connected through one bearing, which can effectively reduce the number of parts, make the overall structure more compact and have better stability.

[0020] The utility model is provided with a lead-out roller at the output end, which can make the goods output more smoothly and reduce the risk of material jamming.

[0021] The first side stop of the present invention staggers and interlocks the blocking wheels of the blocking wheel assembly, effectively reducing the gap between the blocking wheels, thereby effectively preventing problems such as package jamming and improving conveying stability. The connection structure between the bracket and the fixing slot facilitates assembly and greatly reduces the difficulty of equipment maintenance. It also facilitates installation of the blocking wheel assembly and effectively improves the structural stability of the connection between the multi-layer fixing slot and the bracket.

These embodiments are merely typical examples of the application of the technical solutions of the present invention. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] The roller centering machine disclosed by the present invention is described below in conjunction with the accompanying drawings. Figure 1 As shown, it includes a frame 100 and obliquely arranged conveying rollers arranged on the frame 100. The obliquely arranged conveying rollers are in two groups and are symmetrically distributed on both sides of an intermediate rod 110. The intermediate rod 110 is mounted on the frame 100.

[0033] The conveying roller includes a first roller 210, a second roller 220 and a group of third rollers 230 arranged in sequence from the first end to the second end of the roller centering machine. The lengths of the first roller 210, the second roller 220 and the third roller 230 increase in sequence. The second roller 220 and the third roller 230 are in contact with the driving belt 310 of the friction driving module 300 and are driven to rotate by the friction driving module 300. The first roller 210 and the second roller 220 are connected by a transmission structure 400 so that the two rotate synchronously.

[0034] The transmission structure 400 includes a transmission roller 410 that is in contact with and located below the first roller 210 and the second roller 220. The transmission roller 410 is rotatably mounted on a roller frame 420, which is connected to the frame in an adjustable height. For example, the roller frame 420 includes a U-shaped groove, with a support rod 421 connected to the middle of the bottom of the U-shaped groove. The support rod 421 is a screw, which is secured to the frame via an adjusting nut and a locking nut.

[0035] More preferably, the support rod 421 of the roller frame 420 can be connected to the frame so as to be movable up and down, and the support rod 421 can be a shape other than a circle. The roller frame 420 is connected to an elastic member 430 so that the drive roller 410 thereon is tightly attached. The elastic member 430 is a spring mounted on the support rod 421, one end of the spring abuts against the bottom of the U-shaped groove, and the other end abuts against the frame. At the same time, when the drive roller 410 is in contact with the first roller 210 and the second roller 220, the spring is in a compressed state.

[0036] The conveying rollers on each side of the intermediate rod 110 are driven and conveyed by a friction drive module 300. The friction drive module 300 includes a module frame. The membrane assembly includes an upper frame 320 and a lower frame 330. A group of equal-height and parallel support rollers 340 are provided on the upper frame 320. The support rollers 340 are sleeved with the drive belt 310. The drive belt 310 is also sleeved on a drive roller 350. One end of the support shaft 351 of the drive roller 350 is rotatably connected to one side of the lower frame 330 through a bearing 360. The other end of the support shaft 351 is connected to the reducer 370 on the other side of the lower frame 330. The reducer 370 is connected to the motor 380 that drives the support shaft 351 to rotate.

[0037] The driving belt 310 is also connected to the tensioning roller 390 and the steering roller 301 located on its outside. The tensioning roller 390 and the steering roller 301 are arranged on the lower frame 330 and their top heights are similar. They are located on the same side of the driving roller 350 and can be adjusted in horizontal position on the lower frame 330.

[0038] At the same time, the frame 100 includes a group of parallel and horizontally extending cross bars 120, and the cross bars 120 are provided with circular holes for connecting the friction drive module 300. The lower side panels of the upper frame 320 of the friction drive module 300 are horizontally bent 90° to the outside to form a horizontal bending portion 321, and the horizontal bending portion 321 is formed with a connecting hole corresponding to the circular hole. A pad 302 is also provided between the friction drive module 300 and the cross bar 120, and the screw connecting the horizontal bending portion 321 and the cross bar 120 passes through the pad 302, and the pad 302 can be designed to have various thicknesses as needed to ensure that the drive belt 310 is fully fitted with the bottom of the conveying roller.

[0039] A first side block 500 and a second side block 600 are further provided on both sides of the frame 100 . The two first side blocks 500 are symmetrically provided with output ends and form a bell mouth. The two second side blocks 600 extend along the length direction of the drum centering machine.

[0040] The first side guard 500 includes a bracket 510 fixed to the frame 100. The bracket 510 is located at a top corner of one side of the output end of the roller centering machine. The bracket 510 includes vertical side panels, each of which is provided with a vertical connecting plate extending toward one side of the inclined conveyor roller. The vertical connecting plate at the outer end is connected to the fixed plate at the output end of the frame 100, and the vertical connecting plate at the inner end is connected to the end of the second side guard 600. The lower side of the vertical side panel is connected to a horizontal fixing plate, which is fixed to the frame 100. A reinforcement plate is provided between the horizontal fixing plate and the vertical side panel. The bracket 510 is provided with multiple layers of installation space. Specifically, the bracket 510 is provided with multiple layers of fixing slots 520, each of which constitutes an installation space, and each fixing slot 520 is provided with a row of the blocking wheel assemblies 530.

[0041] In order to facilitate the assembly of the bracket 510 and the fixing slot 520, a plurality of corresponding waist-shaped holes 540 are provided on the vertical connecting plate of the bracket 510 and each fixing slot 520. The bracket 510 and the fixing slot 520 are fastened together by a T-shaped screw 550 and a nut 560 passing through the waist-shaped hole. One end of the T-shaped screw is a horizontal portion. The thickness of the horizontal portion is equivalent to the width of the waist-shaped hole 540 so that it can pass through the waist-shaped hole 540. The length of the horizontal portion is greater than the width of the waist-shaped hole 540 so that the horizontal portion rotates a certain angle, such as 90°, after passing through the waist-shaped hole 540. At this time, the two wings of the horizontal portion are stuck on both sides of the waist-shaped hole 540 and cannot be withdrawn from the waist-shaped hole 540. Therefore, the nut 560 and the T-shaped screw 550 can be locked from the outside of the bracket 510.

[0042] In order to facilitate the installation of the rotating shaft of the wheel block assembly 530, the fixing groove 520 includes a C-shaped first part 521, and the upper and lower ends of the first part 521 respectively engage the second part 522. The second part 522 is also C-shaped and the opening is facing the first part 521. The upper horizontal plate and the lower horizontal plate of the second part 522 are respectively provided with a row of connecting holes in opposite positions. The end of the rotating shaft of the wheel block assembly 530 can be conveniently connected to the second part 522 through the connecting holes in opposite positions.

[0043] Furthermore, to improve the support of the overall structure, the top of the first portion 521 is flush with the top of the second portion 522 at the upper end, and the bottom of the first portion 521 is flush with the bottom of the second portion 522 at the lower end. After the fixing slots 520 are assembled on the bracket 510, the first portions 521 of adjacent fixing slots 520 abut against each other, and the second portions 522 of adjacent fixing slots 520 abut against each other. This allows the fixing slots 520 on the lower layer to effectively support the fixing slots 520 on the upper layer, thereby reducing the shear force on the cross-shaped bolts.

[0044] The blocking wheel assembly 530 includes a group of concentric blocking wheels with axes extending in the vertical direction. The blocking wheels of adjacent blocking wheel assemblies 530 are staggered in the vertical direction and the projections of the blocking wheels of adjacent blocking wheel assemblies 530 on the horizontal plane partially overlap. More preferably, the diameter of the blocking wheel is slightly smaller than the distance between the two rotating shafts of adjacent blocking wheel assemblies 530, and the thickness of the blocking wheel is slightly smaller than the distance between adjacent blocking wheels on the blocking wheel assembly 530, so that the gap between the blocking wheel assemblies 530 is as small as possible.

[0045] As attached Figure 1 As shown, in order to improve the smoothness of the output of goods, the output end of the roller centering machine is provided with an output roller 700 located in the middle position and with its axis extending along the width direction of the roller centering machine.
