Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and specifically to a multi-axis synchronous polishing and deburring device for shaft components. Background Technology

[0002] A deburring and polishing device for deburring and polishing the surface of metal shafts is provided, comprising a frame, a cylinder fixedly connected to the left side of the frame, a cylinder push rod fixedly connected to the right side of the cylinder, an elbow clamp fixedly connected to the right side of the frame, a compression block fixedly connected to the right side of the elbow clamp, a clamping guide post inside the frame, a rolling bearing, a spring and a transmission sprocket fixedly connected to the outer side of the clamping guide post, a sliding wheel rotatably connected to the left side of the clamping guide post, a polishing shaft rotatably connected between the frame members, a rotating sprocket and a polishing wheel fixedly connected to the outer side of the polishing shaft, a rotary motor and a transmission motor fixedly connected to the lower surface inside the frame, a rotating chain drivingly connected to the left side of the rotary motor, a drive wheel rotatably connected to the right side of the transmission motor, a driven wheel meshing with the top of the drive wheel, a driven wheel rotatably connected to the right side of the drive wheel, a transmission chain drivingly connected to the outer side of the driven wheel, a proximity switch fixedly connected inside the frame, and shafts movably connected between the clamping guide posts.

[0003] The machine works as follows: When the rotary motor is energized, it drives the rotary chain to rotate. The rotary chain drives the rotary sprocket to rotate, which in turn drives the polishing shaft to rotate. The polishing shaft drives the polishing wheel to rotate, which in turn drives the shaft to rotate. When the transmission motor is energized, it drives the drive wheel to rotate, which in turn drives the driven wheel to rotate. The driven wheel drives the transmission chain to run, which in turn drives the transmission sprocket to rotate. The transmission sprocket drives the clamping guide column to move along the track path inside the frame. When it reaches the loading position, the clamping guide column moves to the left under the action of the spring. At this time, the distance between the two clamping guide columns is greater than the length of the shaft. The shaft is placed between the two clamping guide columns, and the elbow clamp handle is moved to clamp the shaft. The transmission chain drives the clamping guide column to continue running. When it reaches the unloading position, the clamping guide column is released, and the shaft falls into the output port.

[0004] The existing polishing and deburring equipment suffers from several problems. First, relying solely on the rotation of the polishing wheel to rub and drive the shaft rotation cannot guarantee that each shaft will complete a full rotation, compromising both polishing effectiveness and completeness. Second, to ensure the polishing wheel contacts the shaft, the distance between their axes must be less than half the sum of their axes. However, with the polishing wheel's axis position fixed, when the transmission chain circulates through multiple shafts, each shaft will collide with the polishing wheel in front of it, and the combined force of these collisions affects the transmission chain's operation. Third, loading requires the robotic arm to accurately align with the first clamping position, demanding high control precision from both the robotic arm and the transmission chain. Furthermore, the robotic arm must wait for the clamping action to complete, impacting the overall quality. Finally, the unloading method, where shafts fall off after being released from clamps, easily damages high-precision shafts, and the irregular placement of fallen shafts hinders subsequent automation. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-axis synchronous polishing and deburring device that improves the deburring and polishing effect, enhances the smoothness of automated shaft delivery, and better protects the shaft.

[0006] The first objective of this invention is to provide a multi-axis synchronous polishing and deburring device, comprising a feeding device and a processing device. The processing device includes a processing wheel and a first rotary drive assembly for rotating the processing wheel. The feeding device passes through a processing station and is positioned at the processing station. The feeding device can deliver shaft components along a straight line. The feeding device includes a first support mechanism and a second support mechanism. The first support mechanism has a plurality of first placement positions arranged at intervals along a straight line, and the second support mechanism has a plurality of second placement positions arranged at intervals along a straight line. The feeding device also includes a first lifting drive assembly and a first translation drive assembly. The first lifting drive assembly drives the first support mechanism to rise and fall between a high position and a low position, and the first translation drive assembly drives the second support mechanism to reciprocate along a straight line. The multi-axis synchronous polishing and deburring device also includes a processing device. The clamping and rotating device at the workstation includes two clamping working parts arranged on both sides of the feeding device laterally. Each clamping working part includes a clamping member. At least one clamping working part includes a second translation drive assembly that drives its clamping member to translate laterally, and at least one clamping working part includes a second rotation drive assembly that drives its clamping member to rotate. When the first support mechanism is in a high position, the first placement position is higher than the second placement position, and at this time the clamping member is directly facing the first placement position laterally. When the first support mechanism is in a low position, the first placement position is lower than the second placement position, and at this time the second support mechanism can move along a straight line to transfer the shaft on the second placement position. The processing device also includes a third lifting drive assembly and a third translation drive assembly. The third lifting drive assembly drives the processing wheel to lift, and the third translation drive assembly drives the processing wheel to translate.

[0007] As can be seen from the above scheme, the present invention uses a liftable first support mechanism and a translational second support mechanism in coordination to complete the gradual transfer of the shaft between multiple first placement positions. The shaft is primarily supported and transferred linearly between multiple workstations. This arrangement facilitates direct picking and placing of workpieces by the robotic arm during feeding and unloading, eliminating the need for axial loosening as required by existing technologies and preventing dropped parts from being ejected, thus protecting the shaft. Furthermore, based on the support and delivery arrangement of this feeding device, the axial ends of the shaft do not cooperate with the feeding device. Therefore, the present invention also utilizes the axial ends of the shaft, setting up clamping and rotating devices at the processing station to clamp and rotate the axial ends of the shaft. This arrangement ensures stable rotation of the shaft at the processing station, thereby guaranteeing the integrity of deburring and polishing. Finally, the present invention features a liftable and translational processing wheel, which not only completes deburring and polishing of the shaft but also rises after processing to avoid transporting the shaft, thereby improving the smoothness of automated shaft delivery.

[0008] A further embodiment is that the first support mechanism includes two sets of first support components arranged laterally opposite each other, each first support component having a plurality of first axis positioning seats arranged at intervals along a straight line, and a first placement position being formed between a pair of first axis positioning seats arranged laterally opposite each other; and / or, the second support mechanism includes two sets of second support components arranged laterally opposite each other, each second support component having a plurality of second axis positioning seats arranged at intervals along a straight line, and a second placement position being formed between a pair of second axis positioning seats arranged laterally opposite each other.

[0009] As can be seen from the above, under this configuration, the first support mechanism and / or the second support mechanism can stably support both sides of the shaft while minimizing space occupation, ensuring that the shaft can be smoothly transmitted.

[0010] A further proposed solution is that the first axis positioning seat adopts a V-type seat, and / or the second axis positioning seat adopts a V-type seat.

[0011] As can be seen from the above, this setting can ensure the accuracy of the shaft center position, which is beneficial to the accuracy of deburring and polishing, the success rate of clamping and rotating devices, and the success rate of automated loading and unloading robots.

[0012] A further embodiment is that the first lifting drive assembly includes a first drive unit, a first rotating shaft, a first gear, a first fixed seat, a lifting seat, and a first rack; the first drive unit drives the first rotating shaft to rotate around the fixed axis, the first gear is installed on the first rotating shaft and rotates synchronously with the first rotating shaft; the first lifting seat is slidably connected to the first fixed seat in a vertical direction, the first rack is connected to the lifting seat and extends in a vertical direction, and the lifting seat is connected to the first support assembly.

[0013] As can be seen from the above, because the first support component extends a relatively long distance along the straight direction, using only a single cylinder or motor to lift the first support component at one point would result in poor mechanical conditions at other locations along the long length of the first support component, which would be detrimental to its operational stability. Therefore, a motor drives a first rotating shaft, which in turn drives multiple first gears to rotate. With the meshing of the first gears and the first rack, multiple lifting seats rise and lift various locations along the length of the first support component, thus ensuring that all parts of the first support component are supported and more stable.

[0014] A further embodiment is that the first translation drive assembly includes a second drive unit, a first lead screw, and a first lead screw nut. The second drive unit drives the first lead screw to rotate, and the first lead screw nut is fitted onto the first lead screw and connected to the second support assembly.

[0015] As can be seen from the above, using a lead screw assembly to drive the second support assembly has the advantages of controllable reciprocating motion and high control precision.

[0016] A further proposed solution is that, in the horizontal direction, two sets of second support components are arranged inside the two sets of first support components, and two clamping working parts are located outside the two sets of first support components; at least a portion of the first lifting drive component is arranged below the first support components, and at least a portion of the first translation drive component is arranged between the two sets of second support components.

[0017] As can be seen from the above, the first support component, the second support component, the first lifting drive component, and the first translation drive component are all elongated structures along a straight line. With this configuration, the space below the first support component and the second support component can be fully utilized, making the feeding device compact and occupying little space.

[0018] Another further option is that the multi-axis synchronous polishing and deburring equipment also includes a centering device; the clamping and rotating device includes two pushing working parts arranged on both sides of the feeding device, the pushing working parts including a pushing component and a transverse driving assembly that drives the pushing component to move laterally; the feeding device passes through the loading station, the processing station and the unloading station in sequence; one centering device is arranged at the loading station, and / or the other centering device is arranged at the unloading station.

[0019] As can be seen from the above, the centering device ensures that the center position of the shaft being fed in or out is accurate in its own length direction, ensures that deburring and polishing are carried out effectively, and ensures that the shaft is automatically picked up and sent to the next process line in an accurate position, so as to ensure that the position is accurate when entering the next process station and that the next automatic processing process is carried out smoothly.

[0020] Another further embodiment is that the third translation drive assembly includes a fixed frame, a second rack, a second gear, a third drive unit, and a moving platform. The third lifting drive assembly is mounted on the moving platform. The second rack is fixedly mounted on the fixed frame in the lateral direction, and the moving platform is slidably connected to the fixed frame in the lateral direction. The third drive unit is mounted on the moving platform, and the third drive unit drives the second gear to rotate, with the second gear meshing with the second rack. The third translation drive assembly also includes a first auxiliary gear, which is rotatably connected to the moving platform and meshes with the second rack.

[0021] As can be seen from the above, with only one gear engaging with the rack, the rack may wobble due to the gap when it moves. In this configuration, by adding a first auxiliary gear, two gears engage with the rack to ensure the straightness of the rack's movement and improve the stability of the moving platform.

[0022] Another further embodiment is that the third lifting drive assembly includes a fourth drive unit, a third rack, a third gear, and a lifting arm; the lifting arm is slidably connected to the moving platform along the vertical direction, the third rack is set on the lifting arm along the vertical direction, the fourth drive unit is installed on the moving platform, the fourth drive unit drives the third gear to rotate, and the third gear meshes with the third rack; the third lifting drive assembly also includes a second auxiliary gear, the second auxiliary gear is rotatably connected to the moving platform and meshes with the third rack.

[0023] As can be seen from the above, similar to the setting of the first auxiliary gear, the setting of the second auxiliary gear ensures the straightness and stability of the lifting arm's lifting.

[0024] Another further embodiment is that the processing device includes a wheel frame, which is fixed to the lower end of the lifting arm, and the processing wheels are mounted on the wheel frame; the wheel frame includes two support parts that extend downward and are arranged opposite each other along the axial direction of the processing wheels, forming a wheel assembly placement position between the two support parts; the processing device includes a detachable wheel assembly, which includes two detachable connecting parts arranged opposite each other along the axial direction and at least two processing wheels disposed between the two detachable connecting parts; the two detachable connecting parts are detachably connected to the two support parts respectively.

[0025] As can be seen from the above, this configuration makes the processing wheel easy to remove and replace. Attached Figure Description

[0040] See Figure 1 and Figure 2The multi-axis synchronous polishing and deburring equipment of the present invention is used for automated feeding, deburring and polishing of roller shaft parts, followed by automated unloading and transfer to the next process equipment. The multi-axis synchronous polishing and deburring equipment of the present invention includes a main unit 1 and an unloading and transfer device 83. The feeding robot 71 can take the shaft part 9 from the tray on the stacked tray feeding device 81 and transfer it to the feeding station 101 of the main unit 1; after the shaft part 9 has been processed, it is automatically transported to the unloading station 109, and the unloading and transfer device 83 can then transfer the shaft part in the unloading station 109 to the next process equipment.

[0041] See Figure 3 The main unit 1 includes a feeding device 2, a processing device 3, a centering device 4, and a clamping and rotating device 5. The feeding device 2 passes along a straight line through the loading station 101, four processing stations 102, and the unloading station 109. Two centering devices 4 are respectively set for the loading station 101 and the unloading station 109. Each processing station 102 is equipped with a corresponding processing device 3 and a clamping and rotating device 5. The processing device 3 is used for deburring or polishing the shaft parts.

[0042] See Figures 4 to 7 The feeding device 2 can deliver shaft parts along a straight line (x-axis direction in the figure). The feeding device 2 includes a first support mechanism 21 and a second support mechanism 22. The first support mechanism 21 is provided with a plurality of first placement positions 210 arranged at intervals along a straight line, and the second support mechanism 22 is provided with a plurality of second placement positions 220 arranged at intervals along a straight line.

[0043] The first support mechanism 21 includes two sets of first support components 211 arranged laterally opposite each other. Each first support component 211 has a plurality of first axis positioning seats 212 spaced apart in a straight line. A first placement position 210 is formed between the pair of first axis positioning seats 212 arranged laterally opposite each other. Similarly, the second support mechanism 22 includes two sets of second support components 221 arranged laterally opposite each other. Each second support component 221 has a plurality of second axis positioning seats 222 spaced apart in a straight line. A second placement position 220 is formed between the pair of second axis positioning seats 222 arranged laterally opposite each other.

[0044] Furthermore, in this embodiment, in the transverse direction indicated by the y-axis, two sets of second support components 221 are disposed inside the two sets of first support components 211. Furthermore, the first axis positioning seat 212 is a V-shaped seat, and the second axis positioning seat 222 is a V-shaped seat. Furthermore, in this embodiment, along the straight line, the interval between the plurality of first placement positions 210 is equal to the interval between the plurality of second placement positions 220. With this arrangement, the V-shaped seat ensures the accuracy of the shaft's axial position, which is beneficial for the accuracy of deburring and polishing, the success rate of the clamping and rotating device, and the success rate of the automated loading and unloading robot's gripping.

[0045] The feeding device 2 also includes a first lifting drive assembly 23 and a first translation drive assembly 24. The first lifting drive assembly 23 drives the first support mechanism 21 to rise and fall between a high position and a low position, and the first translation drive assembly 24 drives the second support mechanism 22 to reciprocate along a straight line.

[0046] Further, in this embodiment, the first lifting drive assembly 23 includes a first drive unit (not shown in the figure), a first rotating shaft 232, a first gear 233, a first fixed seat 234, a lifting seat 235, and a first rack 236. The first drive unit is a motor, and the output shaft of the motor is coaxially connected to the first rotating shaft 232, thus driving the first rotating shaft 232 to rotate around a fixed axis. The first gear 233 is mounted on the first rotating shaft 232 and rotates synchronously with it. The first lifting seat 235 is slidably connected vertically to the first fixed seat 234, and the first rack 236 is connected to the lifting seat 235 and extends vertically. Figure 6 As shown, the vertical part of the inverted L-shape is vertically floatingly connected to the first fixed seat 234 via a slide rail mechanism, while the horizontal part at the top is connected to the bottom lifting seat 235 of the first support assembly 211.

[0047] like Figure 6 As shown, in this embodiment, the first lifting drive assembly 23 is provided with a plurality of lifting seats 235 spaced apart along a straight line for each side of the first support assembly 211. The plurality of lifting seats 235 are connected to various positions along the length of the first support assembly 211. Of course, each lifting seat 235 is provided with a first rack 236. Thus, when the first drive unit (motor) rotates, the plurality of first gears 233 drive the plurality of lifting seats 235 to rise and fall respectively, thereby making the first support assembly 211 have the power to rise and fall and be supported at all points along its length. This arrangement improves the mechanical state of the first support assembly 211 and ensures the stability of the lifting action of the first support assembly 211.

[0048] See also Figure 6 The first translation drive assembly 24 includes a second drive unit 241, a first lead screw 242, and a first lead screw nut 243. The second drive unit 241 drives the first lead screw 242 to rotate. The first lead screw nut 243 is fitted on the first lead screw 242 and is fixedly connected to two second support assemblies 221 through a connecting plate 244 and a connecting frame 245.

[0049] See Figure 5 and Figure 7The present invention utilizes a liftable first support mechanism 21 and a translational second support mechanism 22 in coordinated operation to complete the gradual transfer of shaft components between multiple first placement positions 210. Specifically, when the first support mechanism 21 is in a low position, the shaft component is supported on the higher second support mechanism 22. In this state, the second support mechanism 22 can move the shaft component forward to one or more positions when moving in a straight line. That is, this state is used for delivering the shaft component. Specifically, when the first support mechanism 21 is in a low position, the first placement position 210 is lower than the second placement position 220. At this time, the second support mechanism 22 can move the shaft component on the second placement position 220 by moving in a straight line. Subsequently, the first support mechanism 21 rises to a high position and lifts the shaft component that was originally supported on the second support mechanism 22. At this time, the shaft component is supported by the higher first support mechanism 21. This state is used to lift the shaft component for processing or unloading. Mainly, the shaft is supported and transported in a straight line between multiple workstations. This arrangement facilitates the robot to directly pick up and place workpieces during feeding and unloading, eliminating the need to wait for axial loosening as required by existing technologies, and also eliminating the problem of falling out and protecting the shaft. Furthermore, in this embodiment, as Figure 6 As shown, most of the structure of the first lifting drive assembly 23 is located below the first support assembly 211, and most of the structure of the first translation drive assembly 24 is located between the two sets of second support assemblies 221. With this arrangement, the space below the first support assembly 211 and the second support assembly 221 is fully utilized, making the feeding device 2 compact and occupying little space, thereby reserving more sufficient space on the lateral outer side for the placement of the centering device 4 and the clamping rotation device 5.

[0050] See Figure 8 and Figure 9 The centering device 4 includes two pushing working parts 401 arranged on both sides of the feeding device 2. Each pushing working part 401 includes a pushing member 43 and a transverse drive assembly 41 that drives the pushing member 43 to move laterally. The pushing side of the pushing member 43 is provided with four buffer members 44, spaced equidistant from the multiple first placement positions 210 along a straight line (x-axis direction). The transverse drive assembly 41 includes a motor, a lead screw assembly, and a slide 42. The motor housing drives the slide 42 to move laterally, and the slide 42 is connected to the pushing member 43. Additionally, a spring 45 arranged laterally is provided between the output end of the pushing member 43 and the slide 42 as a buffer structure. With this configuration, the centering device 4 ensures the accurate center position of the fed or discharged shaft along its length, ensures effective deburring and polishing, and ensures the shaft is automatically gripped and delivered to the next automated processing line in an accurate position, guaranteeing accurate positioning when entering the next processing station and ensuring smooth operation of the next automated processing step.

[0051] See Figure 8 and Figure 10 The clamping and rotating device 5 includes two clamping working parts 501 disposed on both sides of the feeding device 2. Each clamping working part 501 includes a clamping member 53. At least one clamping working part 501 includes a second translation drive assembly 51 that drives its clamping member 53 to translate laterally, and at least one clamping working part 501 includes a second rotation drive assembly 52 that drives its clamping member 53 to rotate. In this embodiment, both clamping working parts 501 are provided with the second translation drive assembly 51, while only one side of the clamping working part 501 is provided with the second rotation drive assembly 52. ​​The second translation drive assembly 51 can adopt existing technologies in the art, such as a combination of a motor and a lead screw assembly, a linear module, or a linear cylinder; the second rotation drive assembly 52 can adopt existing technologies in the art, including a motor. The clamping member 53 is provided with a tapered portion, which can be inserted into a hole at the axial end of the shaft member 9. Under the lateral clamping action, when the second rotation drive assembly 52 works, the shaft member 9 rotates synchronously with the clamping member 53. When the first support mechanism 21 is in a high position, the first placement position 210 is higher than the second placement position 220, and at this time the clamping member 53 is directly opposite a first placement position 210 in the lateral direction.

[0052] See Figure 9 and Figure 10 In each processing station 102, the two clamping working parts 501 of the clamping and rotating device 5 are located on the outside of the two sets of first support components 211, and the two pushing working parts 401 of each centering device 4 are located on the outside of the two sets of first support components 211.

[0053] See Figure 11 and Figure 12In this embodiment, each of the four processing stations includes a third translation drive assembly 32 and a third lifting drive assembly 33. Taking one of the processing stations as an example, the third translation drive assembly 32 includes a fixed frame 31, a second rack 343, a second gear 342, a third drive unit 341, and a moving platform 320. The third lifting drive assembly 33 is mounted on the moving platform 320. The second rack 343 is fixedly mounted on the fixed frame 31 laterally, and the moving platform 320 is slidably connected to the fixed frame 31 laterally. The third drive unit 341 is mounted on the moving platform 320 and drives the second gear 342 to rotate. The second gear 342 meshes with the second rack 343. The third translation drive assembly 32 also includes a first auxiliary gear 344, which is rotatably connected to the moving platform 320 and meshes with the second rack 343. The third lifting drive assembly 33 includes a fourth drive unit 351, a third rack 353, a third gear 352, and a lifting arm 33. The lifting arm 33 is slidably connected to the moving platform 320 vertically. The third rack 353 is vertically disposed on the lifting arm 33. The fourth drive unit 351 is mounted on the moving platform 320 and drives the third gear 352 to rotate. The third gear 352 meshes with the third rack 353. The third lifting drive assembly 33 also includes a second auxiliary gear 354, which is rotatably connected to the moving platform 320 and meshes with the third rack 353. Finally, the processing device 3 also includes a second processing wheel 37 and a motor 36 that drives the second processing wheel 37 to rotate. The second processing wheel 37 is the processing wheel of the present invention, and the motor 36 is the first rotation drive assembly of the present invention. The motor 36 is fixedly mounted on the lower end of the lifting arm 33. In this configuration, the present invention provides a lifting and sliding processing wheel 391, which can not only deburr and polish the shaft, but also rise to avoid transporting the shaft after processing, thereby improving the smoothness of automated delivery of the shaft.

[0054] Furthermore, by adding a first auxiliary gear 344, the two wheels cooperate with the rack to ensure the straightness of the rack's movement and improve the stability of the moving platform 320. Similarly, the second auxiliary gear 354 ensures the straightness and stability of the lifting arm 33's lifting. Furthermore, in this embodiment, the second rack 343, the second gear 342, the first auxiliary gear 344, the third rack 353, the third gear 352, and the second auxiliary gear 354 all employ helical teeth, which further enhances transmission stability.

[0055] See Figure 13In another processing device 3, the processing device 3 includes a wheel frame 38 and a detachable wheel assembly 39. The detachable wheel assembly 39 includes two detachable connecting parts 392 arranged axially opposite each other and four processing wheels 391 disposed between the two detachable connecting parts 392, and also includes a drive shaft 399 passing through the four processing wheels 391. The detachable connecting parts 392 serve as bearing seats for the drive shaft 399, and the drive shaft 399 is rotatably connected to the two detachable connecting parts 392. The wheel frame 38 is fixed to the lower end of the lifting arm, and the processing wheels 391 are mounted on the wheel frame 38. The first rotary drive assembly 37 includes a motor disposed within the wheel frame 38 and a transmission belt assembly 37 disposed on one side of the wheel frame 38. The motor, the transmission belt assembly 37, and the transmission shaft 399 are sequentially connected in a driving relationship. The wheel frame 38 includes two downwardly extending support portions 381 arranged opposite each other along the axial direction of the processing wheel 391, forming a wheel assembly placement position 380 between the two support portions 381; the processing device 3 includes a detachable wheel assembly 39, with two detachable connecting portions 392 detachably connected to the two support portions 381 respectively. This arrangement makes it easy to disassemble and replace the processing wheel 391.

[0056] Combined Figure 2 Furthermore, in this embodiment, the outer shell structure 11 of the main body 1 is provided with an openable and closable window 110 facing the wheel assembly placement position 380 in a horizontal direction perpendicular to the drive shaft 399. This embodiment also includes a transport forklift 89, which is used to transport the detachable wheel assembly 39. The forks of the transport forklift 89 can carry another detachable wheel assembly 39 and send it into the wheel assembly placement position 380 in the main body 1 through the window 110, thereby reducing the difficulty of replacing the detachable wheel assembly 39.

[0057] Additionally, see Figure 1 and Figure 14 The discharge conveying device 83 includes a track 82 and a manipulator 831 that can translate along the track 82 and can be raised and lowered. The lower end of the manipulator 831 is equipped with four gripping mechanisms 832 for gripping shafts 9. Specifically, two of the gripping mechanisms 832 are mounted on the manipulator 831 via vertical cylinders 833, meaning that two of the gripping mechanisms 832 can be raised and lowered relative to the other two. This arrangement allows the multiple gripping mechanisms 832 of the discharge conveying device 83 to be at different heights to meet the specific docking requirements of multiple processing devices.
