[0014] A method for operating a ramp conveyor line based on continuous transport includes ground line steps and overhead line steps:

[0015] The steps for establishing the ground line are as follows:

[0016] Step 1: The workpiece is lifted onto the slide by the inlet elevator and enters the acceleration entry zone. When the workpiece is transferred to the exit of the inlet elevator, it is accelerated by the first fast friction drive and sent into the first medium speed deceleration zone.

[0017] Step 2: The skateboard enters the first medium-speed deceleration zone and is first decelerated by the first medium-speed friction drive. Then, the transmission speed of the skateboard is read by the first dual-wheel encoder, and the transmission speed of the first medium-speed friction drive is adjusted according to the transmission speed of the skateboard. After passing the first dual-wheel encoder, the skateboard enters the first slow-speed working zone.

[0018] Step 3: The skateboard enters the first slow-speed working area and is decelerated in the second stage by the first slow-speed friction drive. The skateboard contacts the slow-speed friction drive and the transmission speed of the skateboard is read by the first single wheel encoder on the rear. The speed of the first slow-speed friction drive is adjusted according to the transmission speed of the skateboard. After passing through the first slow-speed friction drive, the skateboard is conveyed into the first ramp area.

[0019] Step 4: The skateboard enters the first ramp area, which is a downhill section. The skateboard is accelerated and transported to the acceleration zone in front of the turntable by the second fast friction drive in conjunction with the first adaptive pressure wheel.

[0020] Step 5: The skateboard enters the acceleration zone in front of the turntable, where it is accelerated by the third rapid friction drive in conjunction with the first pressure wheel, and then enters the first transition channel zone.

[0021] Step Six: The skateboard enters the first rotating platform in the first transition channel area. After the first rotating platform rotates, it faces the first channel. The guide wheels on both sides of the first channel rotate and open to a vertical position. The guide wheels guide the skateboard. At this time, the first signal light is red, and passage is not allowed in the first channel of the first transition channel area. The skateboard is driven by the rapid friction of the first channel and accelerated by the second pressure wheel. After passing through the first channel, it enters the second rotating platform. At this time, the guide wheels on both sides of the first channel rotate to a horizontal position. The first signal light is green, and passage is allowed in the first channel. At the same time, the second rotating platform sends the skateboard into the acceleration area behind the rotating platform.

[0022] Step 7: After the skateboard enters the acceleration zone of the turntable, it is accelerated by the fourth rapid friction drive and the third pressure wheel, and transported into the second ramp area.

[0023] Step 8: The skateboard enters the second ramp area, which is an uphill section. The skateboard is driven uphill by the fifth fast friction drive and the matching second adaptive pressure wheel. The structure of the second adaptive pressure wheel is the same as that of the first adaptive pressure wheel. The skateboard is then sent into the second medium speed deceleration zone.

[0024] Step 9: The skateboard enters the second medium-speed deceleration zone, is driven by the second medium-speed friction drive and undergoes the first stage of deceleration. Then, the transmission speed of the skateboard is read by the second dual-wheel encoder, and the transmission speed of the second medium-speed friction drive is adjusted according to the transmission speed of the skateboard. After passing the second dual-wheel encoder, the skateboard enters the second slow-speed working zone.

[0025] Step 10: The skateboard enters the second slow-speed working area and is decelerated for the second stage by the second slow-speed friction drive. The skateboard contacts the slow-speed friction drive and the transmission speed of the skateboard is read by the second single wheel encoder on the rear. The speed of the second slow-speed friction drive is adjusted according to the transmission speed of the skateboard. After passing through the second slow-speed friction drive, the skateboard is conveyed into the acceleration departure area.

[0026] Step 11: The slide plate enters the acceleration and departure zone. The slide plate is first accelerated by the sixth rapid friction drive and sent into the exit elevator. The exit elevator lifts the workpiece out. The slide plate leaves the exit elevator and is accelerated by the seventh rapid friction drive and sent into the second transition channel zone.

[0027] Step 12: The skateboard enters the third rotating platform in the second transition channel area. After the third rotating platform rotates, it faces the second channel. The second channel guide wheels on both sides of the second channel rotate and open to the vertical position. The second channel guide wheels guide the skateboard. At this time, the second signal light is red, and passage is not allowed in the second channel of the second transition channel area. The skateboard is driven by the rapid friction of the second channel and accelerated by the fourth pressure wheel. After passing through the second channel, it enters the fourth rotating platform. At this time, the second channel guide wheels on both sides of the second channel rotate to the horizontal position, the second signal light is green, and passage is allowed in the second channel.

[0028] Step 13: The slide plate is inspected on the fourth rotary table; when the slide plate malfunctions, the fourth rotary table rotates to face the spare area and sends the faulty part to the spare area for repair; when the slide plate is not faulty, the fourth rotary table rotates to face the acceleration entry area, the slide plate is accelerated by the eighth rapid friction drive and sent to the entrance elevator position to match the workpiece to be processed, realizing the cycle;

[0029] The above-ground wiring steps are as follows:

[0030] On a smooth track, the aerial vehicle is transported directly on the continuous track by friction drive.

[0031] On the inclined rail, the counterweight of the air carrier hangs down naturally due to gravity. When the air carrier enters at the fork, the chain protrusion gets stuck between the counterweight. The air carrier is driven by the main chain set inside the inclined rail. The main chain is driven by the motor and runs repeatedly. The main chain drives the air carrier to climb the inclined rail.

[0032] The beneficial effects of this invention are as follows:

[0033] This invention features a compact structure and a rational layout. The production line is divided into a ground line and an overhead line. On the ground line, a combination of fast, medium, and slow friction drives enables the slide to move slowly in the manual work area, facilitating worker operations, and to move quickly in unmanned areas, increasing efficiency. On the incline section, a combination of fast friction drive and adaptive pressure rollers eliminates the need for a lift, reducing production cycle time. The operating height is more ergonomic, improving production and assembly efficiency and ensuring continuity in the production process.

[0034] The present invention also has the following advantages:

[0035] (1) In the climbing section of the aerial line, the present invention uses chain drive to drive the aerial carrier forward, the transmission structure is stable, and the problem of the aerial carrier slipping backward is avoided.

[0036] (2) The present invention sets up a dual-wheel encoder in the transmission direction of medium-speed friction drive and a single-wheel encoder in the transmission direction of slow-speed friction drive in the ground line. The real-time sliding plate transmission speed detected by the dual-wheel encoder and the single-wheel encoder can be used to adjust the speed of medium-speed friction drive and slow-speed friction drive in a targeted manner, so that the distribution of transmission speed is more reasonable.

[0037] (3) Before entering the slow operation area, the present invention performs two decelerations on the slide plate that is rapidly transferred from the uninhabited area, instead of directly reducing the speed. The deceleration process is more reasonable and ensures the stability of the workpiece. Attached Figure Description

The anti-skid chain 58 and the anti-skid plate 59 are fixed by a connecting shaft 64 and limited by a cotter pin 62. A retaining ring 65 is also provided between the anti-skid plate 59 and the anti-skid chain 58. A copper sleeve 63 is provided on the outside of the connecting shaft 64.

[0058] Specifically, the counterweights 57 on the air carrier 51 droop naturally under gravity. When the air carrier 51 enters the fork 53, the chain protrusions 55 are precisely wedged between the counterweights 57. The air carrier 51 moves with the main chain 54. In addition, an anti-slip chain 58 is added next to the main chain 54. The first buffer block 60 and the second buffer block 61 are made of polyurethane and are screwed to both sides of the anti-slip plate 59. The anti-slip plate 59 droops naturally under gravity, and the first buffer block 60 supports the chain links of the anti-slip chain 58. In case the main chain 54 suddenly breaks, the second buffer block 61 can catch the stop block 56 to prevent the air carrier 51 from slipping backward and causing equipment damage. The anti-slip plate 59 is fixed to the anti-slip chain 58 by the connecting shaft 64 and limited by the cotter pin 62. The connecting shaft 64 is lubricated by a copper sleeve 63 on the outside, and the retaining ring 65 can reduce the friction between the anti-slip plate 59 and the anti-slip chain 58, facilitating rotation. Unlike rigid connections, counterweight 57 and anti-reverse plate 59 are not easily damaged and can rotate flexibly and adaptively.

[0059] like Figure 4 As shown, in this embodiment, the structure of the skateboard 6 is as follows: it includes a limiting wheel 601 that engages with the track steel structure 602 to constrain the X-direction; a main support wheel 605 is installed at the bottom of the board to constrain the Z-direction; and a front support 606 and a rear support 607 are respectively provided on the front and rear sides, which can be configured as lifting structures; a cleaning device 604 is provided on the front side of the main support wheel 605 in the forward direction, the cleaning device 604 including bristles and a wire brush; a front hook 603 is installed at the front end of the board and a rear hook 608 is installed at the rear end of the board, the rear hook 608 of the previous skateboard 6 can match the front hook 603 of the next skateboard 6, so that multiple skateboards 6 can travel together; when it is necessary to detach, an arched rail 609 is provided along the length direction of the track steel structure 602; the cleaning device 604 is composed of conductive bristles and a wire brush body, which removes iron filings and other debris while also preventing static electricity, and is installed in front of the main support wheel 605 in the running direction to prevent iron filings from scratching the main support wheel 605.

[0060] Specifically, the rear hook 608 of skateboard 6 is rotatable. When its roller rolls diagonally upward along the arched rail 609, the height of skateboard 6 remains unchanged, and the rear hook 608 rotates counterclockwise. When its roller moves to the lower part of the arched rail 609, the rear hook 608 rotates clockwise. At this time, the gap between the front and rear skateboards 6 is small, and the rear hook 608 of the front skateboard 6 falls into the notch of the front hook 603 of the rear skateboard 6. Multiple skateboards 6 can move forward synchronously when connected together. Before entering the ramp area, the front and rear skateboards 6 need to be separated. The roller of the rear hook 608 rolls diagonally upward along the arched rail 609 to a high position. The rear hook 608 of the front skateboard 6 disengages from the notch of the front hook 603 of the rear skateboard 6, and the speeds of the front and rear skateboards 6 begin to diverge. When the rear hook 608 rolls diagonally downward along the arched rail 609, the hook between the front and rear skateboards 6 is completely disengaged.

[0061] like Figures 2-3As shown, in this embodiment, the first adaptive pressure roller 9 and the second adaptive pressure roller 22 have the same structure. Taking the first adaptive pressure roller 9 as an example, the structure of the first adaptive pressure roller 9 is as follows: it includes a guide roller assembly 901, a top plate 902 welded to the guide roller assembly 901, a vertical connecting plate 904 provided on one side of the top plate 902, and an adjusting bolt 903 provided on the vertical connecting plate 904, with the head of the adjusting bolt 903 tightly attached to the top plate 902; the vertical connecting plate 904 is welded above the upper rotating bracket 905, the upper rotating bracket 905 is also connected to the base 907 through a pin 906, a bushing 908 is provided between the upper rotating bracket 905 and the pin 906, and a limiting square steel 909 is provided at the head of the pin 906; a through hole is provided on the upper rotating bracket 905. The screw assembly 910 passes through the through hole in the upper rotating bracket 905 and is welded to the base 907. A wear-resistant sleeve 911 is fitted on the outside of the screw assembly 910, and a spherical spring 912 is also provided around the wear-resistant sleeve 911. A spherical hole sleeve 913 is also fixed in the inner hole of the upper rotating bracket 905. The contact surface between the spherical hole sleeve 913 and the spherical spring 912 is spherical, so that the spherical hole sleeve 913 and the spherical spring 912 are tightly engaged when the upper rotating bracket 905 rotates around the pin 906. A limit bracket 914 is also screwed onto the base 907. A limit block 916 is installed on the limit bracket 914. An adjusting shim 915 is provided between the limit block 916 and the limit bracket 914. The adjusting shim 915 makes the limit block 916 and the upper rotating bracket 905 fit together.

[0062] Specifically, the top plate 902 is welded to the guide wheel assembly 901, and the vertical connecting plate 904 is welded to the upper rotating bracket 905. The adjusting bolt 903 is first fixed to the vertical connecting plate 904, and then fine-tuned by turning the adjusting bolt 903. When the corresponding holes of the guide wheel assembly 901 and the upper rotating bracket 905 are aligned, they are screwed together, and the nut of the adjusting bolt 903 is tightened simultaneously. The head of the adjusting bolt 903 is in close contact with the top plate 902, providing secondary protection and effectively reducing the loosening of the bolts between the guide wheel assembly 901 and the upper rotating bracket 905 during tightening. The base 907 and the upper rotating bracket 905 are connected by a pin 906 and then fixed with a lock nut. A bushing 908 between the upper rotating bracket 905 and the pin 906 provides lubrication. The head of the pin 906 has a limiting square steel 909 to prevent the pin 906 from rotating. The screw assembly 910 passes through the hole in the upper rotating bracket 905 and is welded to the base 907. A wear-resistant sleeve 911 is fitted over the outer side of the screw assembly 910 and the inner side of the spherical spring 912 to prevent damage to the screw assembly 910 when the spherical spring 912 extends or retracts. A spherical bushing 913 is fixed inside the inner hole of the upper rotating bracket 905. The mating surfaces of the spherical spring 912 and the spherical bushing 913 are both spherical, ensuring that the spherical spring... 912 and the spherical sleeve 913 fit tightly together. The limiting bracket 914 is screwed onto the base 907. The limiting block 916 is made of nylon, with a smooth surface and good wear resistance. There is an adjusting shim 915 between the limiting block 916 and the limiting bracket 914, so that the limiting block 916 and the upper rotating bracket 905 fit together. This not only provides support but also does not affect the upper rotating bracket 905 from swinging up and down with the slope. After the slide plate 6 passes through, it automatically resets due to the influence of the spherical spring 912.

[0063] The working method of the ramp conveyor line based on continuous transportation in this embodiment includes a ground line step and an overhead line step;

[0064] like Figure 8 As shown, the specific steps for establishing the ground line are as follows:

[0065] Step 1: The workpiece is lifted onto the slide plate 6 by the inlet elevator 1 and enters the acceleration entry zone 38. When the workpiece is transferred to the exit of the inlet elevator 1, it is accelerated by the first fast friction drive 2 and sent into the first medium speed deceleration zone 39.

[0066] Step 2: The skateboard 6 enters the first medium-speed deceleration zone 39, where it is first decelerated by the first medium-speed friction drive 3. Then, the transmission speed of the skateboard 6 is read by the first dual-wheel encoder 4, and the transmission speed of the first medium-speed friction drive 3 is adjusted according to the transmission speed of the skateboard 6. After passing the first dual-wheel encoder 4, the skateboard 6 enters the first slow-speed working zone 40.

[0067] Step 3: The skateboard 6 enters the first slow working area 40 and is decelerated in the second stage by the first slow friction drive 5. The skateboard 6 contacts the slow friction drive and the transmission speed of the skateboard 6 is read by the first single wheel encoder 7 on the rear side. The speed of the first slow friction drive 5 is adjusted according to the transmission speed of the skateboard 6. After passing through the first slow friction drive 5, the skateboard 6 is transmitted into the first ramp area 41.

[0068] Step 4: The skateboard 6 enters the first ramp area 41, which is a downhill section. The skateboard 6 is accelerated and transported to the front acceleration area 42 of the turntable by the second fast friction drive 8 in conjunction with the first adaptive pressure wheel 9.

[0069] Step 5: The skateboard 6 enters the acceleration zone 42 in front of the turntable, and is accelerated by the third rapid friction drive 10 in conjunction with the first pressure wheel 11. After acceleration, it enters the first transition channel zone 43.

[0070] Step Six: The skateboard 6 enters the first rotating platform 12 of the first transition channel area 43. After the first rotating platform 12 rotates, it faces the first channel 14. The first channel guide wheels 13 on both sides rotate and open to the vertical position. The first channel guide wheels 13 guide the skateboard 6. At this time, the first signal light 15 is red, and passage is not allowed in the first channel 14 of the first transition channel area 43. The skateboard 6 is accelerated by the first channel rapid friction drive 16 in conjunction with the second pressure wheel 17. After passing through the first channel 14, it enters the second rotating platform 18. At this time, the first channel guide wheels 13 on both sides rotate to the horizontal position. At this time, the first signal light 15 is green, and passage is allowed in the first channel 14. At the same time, the second rotating platform 18 sends the skateboard 6 into the acceleration area 44 after the rotating platform.

[0071] Step 7: After the skateboard 6 enters the acceleration zone 44 of the turntable, it is accelerated by the fourth fast friction drive 19 in conjunction with the third pressure wheel 20 and transported into the second ramp zone 45.

[0072] Step 8: Skateboard 6 enters the second ramp area 45, which is an uphill section. Skateboard 6 is driven uphill by the fifth fast friction drive 21 and the matching second adaptive pressure wheel 22. The structure of the second adaptive pressure wheel 22 is the same as that of the first adaptive pressure wheel 9. Skateboard 6 is sent into the second medium speed deceleration zone 46.

[0073] Step 9: The skateboard 6 enters the second medium-speed deceleration zone 46, is driven by the second medium-speed friction drive 23 and undergoes the first stage of deceleration. Then, the transmission speed of the skateboard 6 is read by the second dual-wheel encoder 24, and the transmission speed of the second medium-speed friction drive 23 is adjusted according to the transmission speed of the skateboard 6. After passing the second dual-wheel encoder 24, the skateboard 6 enters the second slow-speed working zone 47.

[0074] Step 10: The skateboard 6 enters the second slow-speed working zone 47 and is decelerated for the second stage by the second slow-speed friction drive 25. The skateboard 6 contacts the slow-speed friction drive and is read by the second single wheel encoder 26 on the rear side. The speed of the second slow-speed friction drive 25 is adjusted according to the speed of the skateboard 6. After passing through the second slow-speed friction drive 25, the skateboard 6 is conveyed into the acceleration departure zone 48.

[0075] Step 11: The slide plate 6 enters the acceleration and departure zone 48. The slide plate 6 is first accelerated by the sixth rapid friction drive 27 and sent into the exit elevator 28. The exit elevator 28 lifts the workpiece out. The slide plate 6 leaves the exit elevator 28 and is accelerated by the seventh rapid friction drive 29 and sent into the second transition channel zone 49.

[0076] Step 12: The skateboard 6 enters the third rotating platform 30 of the second transition channel area 49. After the third rotating platform 30 rotates, it faces the second channel 33. The second channel guide wheels 34 on both sides of the second channel 33 rotate and open to the vertical position. The second channel guide wheels 34 guide the skateboard 6. At this time, the second signal light 35 is red, and passage is not allowed in the second channel 33 of the second transition channel area 49. The skateboard 6 is accelerated by the second channel rapid friction drive 31 in conjunction with the fourth pressure wheel 32. After passing through the second channel 33, it enters the fourth rotating platform 36. At this time, the second channel guide wheels 34 on both sides of the second channel 33 rotate to the horizontal position, the second signal light 35 is green, and passage is allowed in the second channel 33.

[0077] Step 13: The slide plate 6 is inspected on the fourth rotary table 36; when the slide plate 6 malfunctions, the fourth rotary table 36 rotates to face the spare area 50 and sends the malfunctioning part to the spare area 50 for repair; when the slide plate 6 is not malfunctioning, the fourth rotary table 36 rotates to face the acceleration entry area 38, the slide plate 6 is accelerated by the eighth fast friction drive 37 and sent to the position of the entrance elevator 1 to match the workpiece to be processed, thus realizing the cycle;

[0078] The specific steps for overhead line are as follows:

[0079] On the smooth track, the aerial carrier 51 is transported directly on the continuous track by friction drive;

[0080] On the ramp rail 52, the counterweight 57 of the air carrier 51 hangs down naturally due to gravity. When the air carrier 51 enters at the fork 53, the chain protrusion 55 gets stuck between the counterweight 57. The air carrier 51 is driven by the main chain 54 set in the ramp rail 52. The main chain 54 is driven by the motor and runs continuously. The upper and lower chains form a circular loop. The main chain 54 drives the air carrier 51 to climb up the ramp rail 52. When the air carrier 51 exits at another fork 53, the chain protrusion 55 slowly disengages from the counterweight 57 and enters the flat track again.

[0081] In this embodiment, for example, the speed of fast friction drive can be set to 45 m / min, the speed of medium friction drive can be set to 26 m / min, and the speed of slow friction drive can be set to 7.8 m / min.

[0082] In this embodiment, for example, when the working conditions do not require people to walk, the setting of the first transition channel area 43 and the second transition channel area 49 can be cancelled, that is, the turntable and channel structure can be cancelled, and the ground line can be set as a continuous track structure.

[0083] Example 2:

[0084] like Figure 7 As shown, when the inclination of the ramp section of the aerial line is less than 5°, the possibility of slipping backward is small. The aerial line can also be made into a continuous transmission track, and multiple aerial fast friction drives 67 are evenly distributed on the transmission track. The ramp section, the process deceleration manual operation section and the ground line are similar. The turning point is set as a continuous curved track 66 to directly transmit the aerial carrier 51. The transmission speed is matched with that of the ground line.

[0085] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. Within the scope of protection of the present invention, any form of modification may be made.

After passing through the first slow friction drive (5), the skateboard (6) is transported into the first ramp area (41). Step 4: The skateboard (6) enters the first ramp area (41), which is a downhill section. The skateboard (6) is accelerated and transported to the front acceleration area (42) of the turntable by the second fast friction drive (8) in conjunction with the first adaptive pressure wheel (9). Step 5: The skateboard (6) enters the acceleration zone (42) in front of the turntable, and is accelerated by the third rapid friction drive (10) in conjunction with the first pressure wheel (11). After acceleration, it enters the first transition channel zone (43). Step 6: The skateboard (6) enters the first rotating platform (12) of the first transition channel area (43). After the first rotating platform (12) rotates, it faces the first channel (14). The first channel guide wheels (13) on both sides rotate and open to the vertical position. The guide wheels guide the skateboard (6). At this time, the first signal light (15) is red, and passage is not allowed in the first channel (14) of the first transition channel area (43). The skateboard (6) is accelerated by the rapid friction drive (16) of the first channel in conjunction with the second pressure wheel (17). After passing through the first channel (14), it enters the second rotating platform (18). At this time, the first channel guide wheels (13) on both sides rotate to the horizontal position. At this time, the first signal light (15) is green, and passage is allowed in the first channel (14). At the same time, the second rotating platform (18) sends the skateboard (6) into the acceleration area (44) after the rotating platform. Step 7: The skateboard (6) enters the acceleration zone (44) of the turntable and is accelerated by the fourth fast friction drive (19) in conjunction with the third pressure wheel (20) and transported into the second ramp zone (45). Step 8: The skateboard (6) enters the second ramp area (45), which is an uphill section. The skateboard (6) is driven uphill by the fifth fast friction drive (21) and the matching second adaptive pressure wheel (22). The structure of the second adaptive pressure wheel (22) is the same as that of the first adaptive pressure wheel (9). The skateboard (6) is sent into the second medium speed deceleration zone (46). Step 9: The skateboard (6) enters the second medium-speed deceleration zone (46), is driven by the second medium-speed friction drive (23) and undergoes the first stage of deceleration. Then, the transmission speed of the skateboard (6) is read by the second dual-wheel encoder (24), and the transmission speed of the second medium-speed friction drive (23) is adjusted according to the transmission speed of the skateboard (6). After passing the second dual-wheel encoder (24), the skateboard (6) enters the second slow-speed working zone (47). Step 10: The skateboard (6) enters the second slow working area (47) and is decelerated for the second stage by the second slow friction drive (25). The skateboard (6) contacts the slow friction drive and is read by the second single wheel encoder (26) on the rear side. The speed of the second slow friction drive (25) is adjusted according to the speed of the skateboard (6). After passing the second slow friction drive (25), the skateboard (6) is transported into the acceleration departure area (48). Step 11: The slide (6) enters the acceleration exit zone (48). The slide (6) is first accelerated by the sixth rapid friction drive (27) and sent into the exit elevator (28). The exit elevator (28) lifts out the workpiece. The slide (6) leaves the exit elevator (28) and is accelerated by the seventh rapid friction drive (29) and sent into the second transition channel zone (49). Step 12: The skateboard (6) enters the third rotating platform (30) of the second transition channel area (49). After the third rotating platform (30) rotates, it faces the second channel (33). The second channel guide wheels (34) on both sides of the second channel (33) rotate and open to the vertical position. The second channel guide wheels (34) guide the skateboard (6). At this time, the second signal light (35) is red. No passage is allowed in the second channel (33) of the second transition channel area (49). The skateboard (6) is accelerated by the second channel rapid friction drive (31) in conjunction with the fourth pressure wheel (32). After passing through the second channel (33), it enters the fourth rotating platform (36). At this time, the second channel guide wheels (34) on both sides of the second channel (33) rotate to the horizontal position. The second signal light (35) is green. Passage is allowed in the second channel (33). Step 13: The slide plate (6) is inspected on the fourth rotary table (36); when the slide plate (6) malfunctions, the fourth rotary table (36) rotates to face the spare area (50) and sends the malfunctioning part to the spare area (50) for repair; when the slide plate (6) is not malfunctioning, the fourth rotary table (36) rotates to face the acceleration entry area (38), the slide plate (6) is accelerated by the eighth fast friction drive (37) and sent to the entrance elevator (1) to match the workpiece to be processed, thus realizing the cycle; The above-ground wiring steps are as follows: On the flat track, the airborne carrier (51) is transported directly on the continuous track by friction drive, while at the turning point it is transported directly on the continuous curved track (66) by airborne rapid friction drive (67). On the ramp rail (52), the counterweight (57) of the air carrier (51) hangs down naturally due to gravity. When the air carrier (51) enters at the fork (53), the chain protrusion (55) is just stuck between the counterweight (57). The air carrier (51) is driven by the main chain (54) set in the ramp rail (52). The main chain (54) is driven by the motor and runs repeatedly, driving the air carrier (51) to climb the ramp rail (52).
