[0014] A working method of a ramp conveyor line based on continuous transportation, including ground line steps and aerial line steps:

[0015] The ground line steps are:

[0016] Step 1: The workpiece is carried onto the slide by the entrance elevator and enters the accelerated entry area. When the workpiece is transported to the exit of the entrance elevator, it is accelerated by the first rapid friction drive and sent into the first medium-speed deceleration area;

[0017] Step 2: The slide enters the first medium-speed deceleration zone and is first decelerated by the first medium-speed friction drive. The first dual-wheel encoder then reads the slide's transmission speed. The transmission speed of the first medium-speed friction drive is adjusted according to the slide's transmission speed. After passing the first dual-wheel encoder, the slide enters the first slow-speed operation zone.

[0018] Step 3: The slide enters the first slow-speed operation area and is decelerated by the first slow-speed friction drive for the second stage. The slide contacts the slow-speed friction drive and the first single-wheel encoder on the rear side reads the slide's transmission speed at this time. The speed of the first slow-speed friction drive is adjusted according to the slide's transmission speed. After passing through the first slow-speed friction drive, the slide is transmitted into the first ramp area.

[0019] Step 4: The slide enters the first ramp area, which is a downhill section. The slide is accelerated by the second fast friction drive and the first adaptive pressure wheel and sent to the acceleration area in front of the rotating table.

[0020] Step 5: The slide enters the acceleration zone in front of the rotating table and is accelerated by the third rapid friction drive in conjunction with the first pinch wheel, and then enters the first transition channel zone after acceleration;

[0021] Step 6: The skateboard enters the first rotating platform of the first transition channel area. After the first rotating platform rotates, it faces the first channel. The first channel guide wheels on both sides rotate and open to a vertical state. The guide wheels guide the skateboard. At this time, the first signal light is red, and the first channel of the first transition channel area is not allowed to pass; the skateboard is driven by the rapid friction of the first channel and accelerated by the second clamping wheel. After passing the first channel, it enters the second rotating platform. At this time, the first channel guide wheels on both sides rotate to a horizontal state. At this time, the first signal light is green, and the first channel is allowed to pass; at the same time, the second rotating platform sends the skateboard into the acceleration area behind the rotating platform;

[0022] Step 7: The slide enters the acceleration zone after entering the rotating platform, is accelerated by the fourth rapid friction drive and the third pressing wheel, and is transported to 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 sent to the second medium-speed deceleration area.

[0024] Step 9: The slide enters the second medium-speed deceleration zone and is driven by the second medium-speed friction drive and performs the first stage of deceleration. The second dual-wheel encoder then reads the slide's transmission speed at this time, and the transmission speed of the second medium-speed friction drive is adjusted according to the slide's transmission speed. After passing the second dual-wheel encoder, the slide enters the second slow-speed operation zone.

[0025] Step 10: The slide enters the second slow-speed operation area and is decelerated by the second slow-speed friction drive. The slide contacts the slow-speed friction drive and the second single-wheel encoder on the rear side reads the slide's transmission speed at this time. The speed of the second slow-speed friction drive is adjusted according to the slide's transmission speed. After passing through the second slow-speed friction drive, the slide is transmitted to the accelerated departure area.

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

[0027] Step 12: The skateboard enters the third rotating platform of 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 a vertical state. The second channel guide wheels guide the skateboard. At this time, the second signal light is red, and the second channel of the second transition channel area is not allowed to pass; the skateboard is driven by the rapid friction of the second channel and cooperates with the fourth clamping wheel to accelerate. After passing 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 a horizontal state, the second signal light is green, and the second channel is allowed to pass;

[0028] Step 13: The slide is inspected on the fourth rotating table. If the slide fails, the fourth rotating table rotates to face the spare area and the faulty part is sent to the spare area for repair. If the slide does not fail, the fourth rotating table rotates to face the accelerated entry area, and the slide is accelerated by the eighth rapid friction drive and sent to the entrance elevator to match the workpiece to be processed, completing the cycle.

[0029] The aerial line steps are:

[0030] On flat tracks, the aerial carrier is transported directly on the continuous track by friction drive;

[0031] On the ramp track, the counterweight blocks of the aerial carrier naturally droop due to the influence of gravity. When the aerial carrier enters the fork, the chain protrusion is stuck between the counterweight blocks. The aerial carrier is driven by the main chain set in the ramp track. The main chain is driven by the motor and runs repeatedly. The main chain drives the aerial carrier to climb along the ramp track. Beneficial effects

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

[0033] The present invention has a compact structure and a reasonable layout. The production line is divided into a ground line and an aerial line. On the ground line, the combination of fast friction drive, medium-speed friction drive and slow friction drive is used to enable the slide to achieve slow transmission in the manual operation area, which is convenient for workers to work, and fast transmission in the unmanned area, thereby improving transmission efficiency. In the climbing section, the combination of fast friction drive and adaptive pressure wheel is used, eliminating the need for a lift, reducing the production cycle, and making the operating height more in line with ergonomics, thereby improving the efficiency of production and assembly and ensuring the continuity of the production process.

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

[0035] (1) The present invention utilizes a chain drive to drive the aerial carrier forward during the climbing section of the aerial line, resulting in a stable transmission structure and avoiding the problem of the aerial carrier sliding backward;

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

[0037] (3) Before entering the slow-speed operation area, the present invention sequentially undergoes medium-speed friction drive and slow-speed friction drive, and decelerates the slide that is quickly transmitted from the unmanned area twice, instead of directly reducing the speed. The deceleration process is more reasonable and ensures the stability of the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

The first buffer block 60 supports the chain plate of the anti-skid chain 58, and the second buffer block 61 is opposite to the rear side of the block 56; the anti-skid chain 58 and the stop plate 59 are fixed by a connecting shaft 64 and limited by a cotter pin 62, and a retaining ring 65 is also provided between the stop 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 counterweight 57 on the aerial vehicle 51 naturally droops due to gravity. When the aerial vehicle 51 enters the fork 53, the chain protrusion 55 is precisely caught between the counterweight 57, and the aerial vehicle 51 moves along the main chain 54. In addition, an anti-skid chain 58 is added next to the main chain 54. The first and second buffer blocks 60, 61 are made of polyurethane and are screwed to either side of the anti-skid plate 59. The anti-skid plate 59 naturally droops due to gravity, and the first buffer block 60 supports the chain of the anti-skid chain 58. In the event that the main chain 54 suddenly breaks, the second buffer block 61 can catch the block 56, preventing the aerial vehicle 51 from sliding backward and causing damage to the equipment. The anti-skid plate 59 is fixed to the anti-skid chain 58 via a connecting shaft 64 and is retained by a cotter pin 62. The outer side of the connecting shaft 64 is lubricated with a copper sleeve 63. The retaining ring 65 reduces friction between the anti-skid chain 58 and the anti-skid plate 59, facilitating rotation. The counterweight 57 and the backstop plate 59 are not easily damaged like a rigid connection and can be flexibly rotated adaptively.

[0059] As shown in Figure 4, in this embodiment, the structure of the skateboard 6 is as follows: it includes a limiting wheel 601 engaged with the track steel structure 602 for constraining the X direction; a main support wheel 605 is installed at the bottom of the plate body for constraining the Z direction; and a front support 606 and a rear support 607 are respectively provided on the front and rear sides, and the front support 606 and the rear support 607 can be set as a lifting structure; a cleaning device 604 is provided on the front side of the main support wheel 605 in the forward direction, and the cleaning device 604 includes bristles and a wire brush; a front hook 603 is installed at the front end of the plate body, and a rear hook 608 is installed at the rear end of the plate body. The rear hook 608 of the front skateboard 6 can be matched with the front hook 603 of the rear skateboard 6, so that multiple skateboards 6 can travel together; when disengagement is required, an arched rail 609 is provided along the length direction of the track steel structure 602; the cleaning device 604 is composed of bristles and a wire brush body of conductive material, which removes iron filings and the like while also preventing static electricity. It 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 the skateboard 6 is rotatable. When its roller rolls obliquely upward along the arch rail 609, the height of the skateboard 6 remains unchanged, and the rear hook 608 rotates counterclockwise. When its roller moves to the oblique lower part of the arch 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 just falls into the recess of the front hook 603 of the rear skateboard 6. Multiple skateboards 6 can be connected together and move forward synchronously. Before entering the ramp area, the front and rear skateboards 6 need to be disengaged, and the roller of the rear hook 608 rolls obliquely upward along the arch rail 609 to reach a high position. The rear hook 608 of the front skateboard 6 disengages from the recess of the front hook 603 of the rear skateboard 6. The speeds of the front and rear skateboards 6 begin to be out of sync. When the rear hook 608 rolls obliquely downward along the arch rail 609, the hooks between the front and rear skateboards 6 are completely disengaged.

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

[0062] Specifically, top plate 902 is welded to guide wheel assembly 901, and vertical connecting plate 904 is welded to upper rotating bracket 905. Adjustment bolt 903 is first fixed to vertical connecting plate 904, then fine-tuned by turning adjustment bolt 903. When the corresponding holes of guide wheel assembly 901 and upper rotating bracket 905 align, they are screwed together, and the nut of adjustment bolt 903 is tightened simultaneously. The head of adjustment bolt 903 is in close contact with top plate 902, providing secondary protection and effectively preventing the bolts between guide wheel assembly 901 and upper rotating bracket 905 from loosening during tightening. Base 907 and upper rotating bracket 905 are connected by pin 906, which is then secured with a lock nut. A bushing 908 is provided between upper rotating bracket 905 and pin 906 for lubrication. The head of pin 906 is secured with a limiter 909 to prevent pin 906 from rotating. The screw assembly 910 passes through the hole of the upper rotating bracket 905 and is welded to the base 907. The wear-resistant sleeve 911 is sleeved on the outside of the screw assembly 910 and the inside of the spherical spring 912 to prevent the spherical spring 912 from damaging the screw assembly 910 when it is extended or retracted. The spherical hole sleeve 913 is fixed in the inner hole of the upper rotating bracket 905. The mating surfaces of the spherical spring 912 and the spherical hole sleeve 913 are both spherical, so that when the upper rotating bracket 905 rotates around the pin 906, the spherical spring 912 and the spherical hole sleeve 913 fit tightly together, the limit bracket 914 is screwed to the base 907, the limit block 916 is made of nylon, the surface is smooth and wear-resistant, and there is an adjustment gasket 915 between the limit block 916 and the limit bracket 914, so that the limit block 916 and the upper rotating bracket 905 fit together, which not only plays a supporting role but also does not affect the upper rotating bracket 905 from swinging up and down with the change of the slope section; after the slide plate 6 passes, 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 of this embodiment includes ground line steps and aerial line steps;

[0064] As shown in Figure 8, the specific steps for the ground line are:

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

[0066] Step 2: The slide 6 enters the first medium-speed deceleration zone 39 and is first decelerated by the first medium-speed friction drive 3. The first dual-wheel encoder 4 then reads the transmission speed of the slide 6 at this time. The transmission speed of the first medium-speed friction drive 3 is adjusted according to the transmission speed of the slide 6. After passing the first dual-wheel encoder 4, the slide 6 enters the first slow-speed operation zone 40.

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

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

[0069] Step 5: The slide plate 6 enters the acceleration zone 42 in front of the rotating table and is accelerated by the third fast friction drive 10 in cooperation with the first pinch wheel 11. After acceleration, it enters the first transition channel zone 43.

[0070] Step 6: The slide 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 a vertical state. The first channel guide wheels 13 guide the slide 6. At this time, the first signal light 15 is red, and the first channel 14 of the first transition channel area 43 is not passable. The slide 6 is accelerated by the first channel rapid friction drive 16 and 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 a horizontal state. At this time, the first signal light 15 is green, and the first channel 14 is passable. At the same time, the second rotating platform 18 sends the slide 6 into the acceleration area 44 behind the rotating platform.

[0071] Step 7: The slide plate 6 enters the acceleration zone 44 after entering the rotating platform, is accelerated by the fourth fast friction drive 19 and the third pinch wheel 20, and is transported to the second ramp zone 45;

[0072] Step 8: The slide 6 enters the second ramp area 45, which is an uphill section. The slide 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 slide 6 is sent to the second medium-speed deceleration area 46.

[0073] Step 9: The slide 6 enters the second medium-speed deceleration zone 46 and is driven by the second medium-speed friction drive 23 to perform the first stage of deceleration. The second dual-wheel encoder 24 then reads the transmission speed of the slide 6 at this time, and the transmission speed of the second medium-speed friction drive 23 is adjusted according to the transmission speed of the slide 6. After passing the second dual-wheel encoder 24, the slide 6 enters the second slow operation zone 47.

[0074] Step 10: The slide 6 enters the second slow operation zone 47 and is decelerated by the second slow friction drive 25. The slide 6 contacts the slow friction drive and the second single-wheel encoder 26 on the rear side reads the speed of the slide 6. The speed of the second slow friction drive 25 is adjusted according to the speed of the slide 6. After passing through the second slow friction drive 25, the slide 6 is transported to the acceleration departure zone 48.

[0075] 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 the workpiece out. 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.

[0076] Step 12: The slide 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 a vertical state. The second channel guide wheels 34 guide the slide 6. At this time, the second signal light 35 is red, and the second channel 33 of the second transition channel area 49 is not passable. The slide 6 is accelerated by the second channel rapid friction drive 31 and the fourth clamping 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 a horizontal state. The second signal light 35 is green, and the second channel 33 is passable.

[0077] Step 13: The slide 6 is inspected on the fourth rotating platform 36. If the slide 6 is faulty, the fourth rotating platform 36 rotates to face the spare area 50, and the faulty part is sent to the spare area 50 for inspection. If the slide 6 is not faulty, the fourth rotating platform 36 rotates to face the accelerated entry area 38, and the slide 6 is accelerated by the eighth rapid friction drive 37 and sent to the entrance elevator 1 to match the workpiece to be processed, completing the cycle.

[0078] The specific steps of the aerial line are:

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

[0080] On the ramp track 52, the counterweight 57 of the aerial carrier 51 naturally droops due to the influence of gravity. When the aerial carrier 51 enters the fork 53, the chain protrusion 55 is just stuck between the counterweight 57. The aerial carrier 51 is driven by the main chain 54 set in the ramp track 52. The main chain 54 is driven by the motor to run repeatedly, and the upper and lower chains form a circular loop. The main chain 54 drives the aerial carrier 51 to climb along the ramp track 52. When the aerial carrier 51 goes out of the other fork 53, the chain protrusion 55 slowly separates from the counterweight 57 and enters the flat track again.

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

[0082] In this embodiment, for example, when the working condition does 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 are cancelled, and the ground line is set to a continuous track structure.

[0083] Example 2:

[0084] As shown in FIG7 , when the slope of the aerial line is less than 5°, the possibility of slipping back is small. The aerial line can also be directly made into a continuous transmission track, and multiple aerial rapid friction drives 67 are evenly distributed on the transmission track. The slope section and the process deceleration manual operation section are similar to the ground line. The turning point is set as a continuous curved track 66 to directly transmit the aerial carrier 51. The transmission speed matches that of the ground line.

[0085] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any modifications may be made within the scope of protection of the present invention.

When the workpiece is transmitted to the exit of the entrance elevator (1), it is accelerated and transmitted by the first fast friction drive (2) and sent into the first medium-speed deceleration area (39); Step 2: The skateboard (6) enters the first medium-speed deceleration area (39), is first decelerated at the first stage by the first medium-speed friction drive (3), and then the transmission speed of the skateboard (6) is read by the first double-wheel encoder (4). According to the transmission speed of the skateboard (6), the transmission speed of the first medium-speed friction drive (3) is adjusted; after the skateboard (6) passes through the first double-wheel encoder (4), it enters the first slow operation area (40); Step 3: The skateboard (6) enters the first slow operation area (40) and is secondarily decelerated by the first slow friction drive (5). The skateboard (6) contacts the slow friction drive, and the transmission speed of the skateboard (6) at this time is read by the first single-wheel encoder (7) at 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 transported into the first ramp area (41). Step 4: The skateboard (6) enters the first ramp area (41). The first ramp area (41) is a downhill section. The skateboard (6) is accelerated and transported by the second fast friction drive (8) in cooperation with the first adaptive pressing wheel (9) and sent into the pre-rotating table acceleration area (42). Step 5: The skateboard (6) enters the pre-rotating table acceleration area (42) and is accelerated by the third fast friction drive (10) in cooperation with the first pressing wheel (11). After acceleration, it enters the first transition channel area (43). Step 6: The skateboard (6) enters the first rotating table (12) in the first transition channel area (43). After the first rotating table (12) rotates to face the first channel (14), the first channel guide wheels (13) on both sides rotate to the vertical state, and 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 first channel fast friction drive (16) in cooperation with the second pressing wheel (17), passes through the first channel (14), and enters the second rotating table (18). At this time, the first channel guide wheels (13) on both sides rotate to the horizontal state. 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 table (18) sends the skateboard (6) into the post-rotating table acceleration area (44). Step 7: The skateboard (6) enters the post-rotating table acceleration area (44) and is accelerated by the fourth fast friction drive (19) in cooperation with the third pressing wheel (20), and is transported into the second ramp area (45). Step 8: The skateboard (6) enters the second ramp area (45). The second ramp area (45) is an uphill section. The skateboard (6) is driven to climb the slope by the fifth fast friction drive (21) and the matching second adaptive pressing wheel (22). The structure of the second adaptive pressing wheel (22) is the same as that of the first adaptive pressing wheel (9). The skateboard (6) is sent into the second medium-speed deceleration area (46). Step 9: The skateboard (6) enters the second medium-speed deceleration area (46), is driven by the second medium-speed friction drive (23) and decelerated at the first stage. Then, the transmission speed of the skateboard (6) at this time is read by the second double-wheel encoder (24). The transmission speed of the second medium-speed friction drive (23) is adjusted according to the transmission speed of the skateboard (6). After passing through the second double-wheel encoder (24), the skateboard (6) enters the second slow operation area (47). Step Ten: The skateboard (6) enters the second slow operation area (47) and is secondarily decelerated by the second slow friction drive (25). The skateboard (6) contacts the slow friction drive, and the transmission speed of the skateboard (6) at this time is read by the second single-wheel encoder (26) at the rear side. The speed of the second slow friction drive (25) is adjusted according to the transmission speed of the skateboard (6). After passing through the second slow friction drive (25), the skateboard (6) is transported into the acceleration departure area (48). Step Eleven: The skateboard (6) enters the acceleration departure area (48). First, the skateboard (6) is accelerated by the sixth fast friction drive (27) and sent into the exit elevator (28), and the exit elevator (28) lifts the workpiece out; the skateboard (6) leaves the exit elevator (28) and is accelerated by the seventh fast friction drive (29) and sent into the second transition channel area (49). Step Twelve: The skateboard (6) enters the third rotating table (30) in the second transition channel area (49). After the third rotating table (30) rotates to face the second channel (33), the second channel guide wheels (34) on both sides of the second channel (33) rotate to the vertical state to guide the skateboard (6). At this time, the second signal light (35) is red, and passage in the second channel (33) of the second transition channel area (49) is not allowed; the skateboard (6) is accelerated by the second channel fast friction drive (31) in cooperation with the fourth pressing wheel (32) and enters the fourth rotating table (36) after passing through the second channel (33). At this time, the second channel guide wheels (34) on both sides of the second channel (33) rotate to the horizontal state, the second signal light (35) is green, and passage in the second channel (33) is allowed. Step Thirteen: The skateboard (6) is inspected on the fourth rotating table (36); when a fault occurs in the skateboard (6), the fourth rotating table (36) rotates to face the spare area (50) to send the faulty part into the spare area (50) for repair; when there is no fault in the skateboard (6), the fourth rotating table (36) rotates to face the acceleration entrance area (38), and the skateboard (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, realizing a cycle. The steps of the overhead line are as follows: On the gentle track, the overhead carrier (51) is directly transported through friction drive on the continuous track, and at the turning point, it is directly transmitted through the overhead fast friction drive (67) on the continuous curved track (66). On the slope track (52), the counterweight (57) of the overhead carrier (51) naturally hangs down under the influence of gravity. When the overhead carrier (51) enters the fork (53), the chain protrusion (55) just gets stuck between the counterweights (57). The overhead carrier (51) is driven by the main chain (54) arranged in the slope track (52). The main chain (54) rotates cyclically after being driven by the motor and drives the overhead carrier (51) to climb the slope track (52).
