An inner conveyor chain track and an outer conveyor chain track are fixed on the frame in the direction of the trolley's movement. The inner conveyor chain track includes an upper inner conveyor chain track and a lower inner conveyor chain track. An annular inner conveyor chain is installed in the upper inner conveyor chain track and the lower inner conveyor chain track. An inner conveyor chain pusher is fixed on the inner conveyor chain. The left end of the inner conveyor chain is the drive section and the right end is the tension section. The inner conveyor chain rotates counterclockwise. The outer conveyor chain track includes an upper outer conveyor chain track and a lower outer conveyor chain track. An annular outer conveyor chain is installed in the upper and lower outer conveyor chain tracks. An outer conveyor chain pusher is fixed on the outer conveyor chain. The left end of the outer conveyor chain is the drive section and the right end is the tension section. The outer conveyor chain rotates counterclockwise. A pusher engagement box assembly with equal height is installed on both the inner and outer sides of the trolley. Each pusher engagement box assembly includes a left pawl and a right pawl, which are hinged to the trolley by pins. The left end of the left pawl is the blocking end, and the right end is the working end; the left end of the right pawl is the working end, and the right end is the blocking end. When the pusher engagement box assembly is in the working state, the blocking ends of the left and right pawls are in contact with the lower surface of the trolley, and both the left and right pawls are in an inclined state. The working end faces of the left and right pawls are both vertically arranged, and the lowest point of the working end face of the left pawl is below the lowest point of the working end face of the right pawl. When the pusher engagement box assembly is in the releasing state, both the left and right pawls are in a horizontal state. In the direction of the trolley's movement, the upper track of the inner conveyor chain is sequentially composed of a tensioning section separation section, a first transition section of the tensioning section, a semi-engaged section of the tensioning section, a second transition section of the tensioning section, a fully engaged section, a drive section transition section, and a semi-engaged section of the drive section. The tensioning section separation section, the semi-engaged section, the fully engaged section, and the semi-engaged section of the drive section are all horizontal rails.

The tensioning section separation section, the semi-engaged section, the fully engaged section, and the semi-engaged section of the drive section are all horizontal. The track consists of two sections: the first transition section and the second transition section of the tensioning section of the upper outer conveyor chain are both ascending tracks; the transition section of the drive section of the upper outer conveyor chain is a descending track; the fully engaged section of the upper outer conveyor chain is located above the semi-engaged sections of the tensioning and drive sections of the upper outer conveyor chain; the semi-engaged sections of the tensioning and drive sections of the upper outer conveyor chain are set at the same height; and both the semi-engaged sections of the tensioning and drive sections of the upper outer conveyor chain are located above the separation section of the upper outer conveyor chain. The installation heights of the separation sections of the tensioning sections of the inner upper track and the outer upper track are equal; the installation heights of the semi-engaged sections of the tensioning sections of the inner upper track and the outer upper track are equal; the installation heights of the fully engaged sections of the inner upper track and the outer upper track are equal; and the installation heights of the semi-engaged sections of the drive sections of the inner upper track and the outer upper track are equal. When the pusher engagement box assembly installed inside the trolley is in working condition and the inner conveyor chain pusher is in the upper track separation section of the inner conveyor chain tensioning section, the highest end of the inner conveyor chain pusher is lower than the lowest end of the working end face of the left pawl and the lowest end of the working end face of the right pawl in the pusher engagement box assembly. When the pusher engagement box assembly installed inside the trolley is in working condition and the inner conveyor chain pusher is in the semi-engaged section of the tensioning section of the upper track of the inner conveyor chain, the highest end of the inner conveyor chain pusher is higher than the lowest end of the working end face of the left pawl in the pusher engagement box assembly and lower than the lowest end of the working end face of the right pawl. When the pusher engagement box assembly installed inside the trolley is in working condition and the inner conveyor chain pusher is in the full engagement section of the upper track of the inner conveyor chain, the highest end of the inner conveyor chain pusher is higher than the lowest end of the working end face of the left pawl and the lowest end of the working end face of the right pawl inside the pusher engagement box assembly. When the pusher engagement box assembly installed inside the trolley is in working condition and the inner conveyor chain pusher is in the half engagement section of the upper track drive section of the inner conveyor chain, the highest end of the inner conveyor chain pusher is higher than the lowest end of the working end face of the left pawl in the pusher engagement box assembly and lower than the lowest end of the working end face of the right pawl. When the pusher engagement box assembly installed on the outside of the trolley is in working condition and the outer conveyor chain pusher is in the separation section of the tensioning section of the upper track of the outer conveyor chain, the highest end of the outer conveyor chain pusher is lower than the lowest end of the working end face of the left pawl and the lowest end of the working end face of the right pawl in the pusher engagement box assembly.

When the pusher engagement box assembly installed on the outside of the trolley is in working condition and the outer conveyor chain pusher is in the full engagement section of the upper track of the outer conveyor chain, the highest end of the outer conveyor chain pusher is higher than the lowest end of the working end face of the left pawl and the lowest end of the working end face of the right pawl in the pusher engagement box assembly. When the pusher engagement box assembly installed on the outside of the trolley is in working condition and the outer conveyor chain pusher is in the half engagement section of the upper track drive section of the outer conveyor chain, the highest end of the outer conveyor chain pusher is higher than the lowest end of the working end face of the left pawl in the pusher engagement box assembly and lower than the lowest end of the working end face of the right pawl. The inner conveyor chain pusher and the outer conveyor chain pusher alternately contact the working end face of the left claw and drive the trolley from right to left; In adjacent outer and inner conveyor chains, the pusher spacing of the outer conveyor chains is equal, and the length of the outer conveyor chain is an integer multiple of the pusher spacing. Similarly, the pusher spacing of the inner conveyor chains is equal, and the length of the inner conveyor chain is an integer multiple of the pusher spacing. The ratio of the distance between the pusher spacing of the outer and inner conveyor chains is equal to the ratio of the running speed of the outer conveyor chain to the running speed of the inner conveyor chain. The pusher spacing of the outer conveyor chains is the distance between adjacent pushers of the outer conveyor chains, and the pusher spacing of the inner conveyor chains is the distance between adjacent pushers of the inner conveyor chains. In the adjacent inner conveyor chain upper track and outer conveyor chain upper track, the semi-engaged section of the drive section of the inner conveyor chain upper track and the semi-engaged section of the tension section of the outer conveyor chain upper track overlap in the front-back direction. Alternatively, in the adjacent inner conveyor chain upper track and outer conveyor chain upper track, the tension section semi-engaged section of the inner conveyor chain upper track and the drive section semi-engaged section of the outer conveyor chain upper track overlap in the front-back direction. Alternatively, in adjacent inner and outer upper tracks of the conveyor chain, the semi-engaged tension section of the inner upper track and the semi-engaged drive section of the outer upper track overlap in the front-to-back direction, and the semi-engaged drive section of the inner upper track and the semi-engaged tension section of the outer upper track overlap in the front-to-back direction.

[0005] Preferably, a pusher engagement box assembly is installed at the same height on both the inner and outer sides of the left end of the trolley.

[0006] This invention achieves seamless connection between adjacent CPC conveyor chains without the need for intermediate transition sections, allowing CPC conveyors to be segmented without damage as needed. This is equivalent to a single CPC conveyor line achieving varying speeds in different zones. It not only meets the needs of different workstations and speeds on the production line, but also allows for segmentation of CPCs at a single speed to address situations where the chain and motor load is insufficient under heavy loads or long-distance conveying. This invention not only solves practical problems in production but also greatly expands the applicability of CPC conveyor lines. Attached Figure Description

When the pusher engagement box assembly installed inside the trolley 2 is in working condition and the inner conveyor chain pusher 5.1 is in the upper track separation section 3.1 of the inner conveyor chain tension section, the highest end of the inner conveyor chain pusher 5.1 is lower than the lowest end of the working end face of the left pawl 2.3 and the lowest end of the working end face of the right pawl 2.4 inside the pusher engagement box assembly; When the pusher engagement box assembly installed inside the trolley 2 is in working condition and the inner conveyor chain pusher 5.1 is in the semi-engaged section 3.3 of the tension section of the upper track of the inner conveyor chain, the highest end of the inner conveyor chain pusher 5.1 is higher than the lowest end of the working end face of the left pawl 2.3 inside the pusher engagement box assembly and lower than the lowest end of the working end face of the right pawl 2.4. When the pusher engagement box assembly installed inside the trolley 2 is in working condition and the inner conveyor chain pusher 5.1 is in the full engagement section 3.5 of the upper track of the inner conveyor chain, the highest end of the inner conveyor chain pusher 5.1 is higher than the lowest end of the working end face of the left pawl 2.3 and the lowest end of the working end face of the right pawl 2.4 inside the pusher engagement box assembly; When the pusher engagement box assembly installed inside the trolley 2 is in working condition and the inner conveyor chain pusher 5.1 is in the semi-engaged section 3.7 of the upper track drive section of the inner conveyor chain, the highest end of the inner conveyor chain pusher 5.1 is higher than the lowest end of the working end face of the left pawl 2.3 inside the pusher engagement box assembly and lower than the lowest end of the working end face of the right pawl 2.4. When the pusher engagement box assembly installed on the outside of the trolley 2 is in working condition and the outer conveyor chain pusher 8.1 is in the tensioning section separation section 6.1 of the upper track of the outer conveyor chain, the highest end of the outer conveyor chain pusher 8.1 is lower than the lowest end of the working end face of the left pawl 2.3 and the lowest end of the working end face of the right pawl 2.4 in the pusher engagement box assembly; When the pusher engagement box assembly installed on the outside of the trolley 2 is in working condition and the outer conveyor chain pusher 8.1 is in the half engagement section 6.3 of the tension section of the upper track of the outer conveyor chain, the highest end of the outer conveyor chain pusher 8.1 is higher than the lowest end of the working end face of the left pawl 2.3 in the pusher engagement box assembly and lower than the lowest end of the working end face of the right pawl 2.4. When the pusher engagement box assembly installed on the outside of the trolley 2 is in working condition and the outer conveyor chain pusher 8.1 is in the full engagement section 6.5 of the upper track of the outer conveyor chain, the highest end of the outer conveyor chain pusher 8.1 is higher than the lowest end of the working end face of the left pawl 2.3 and the lowest end of the working end face of the right pawl 2.4 in the pusher engagement box assembly. When the pusher engagement box assembly installed on the outside of the trolley 2 is in working condition and the outer conveyor chain pusher 8.1 is in the semi-engaged section 6.7 of the upper track drive section of the outer conveyor chain, the highest end of the outer conveyor chain pusher 8.1 is higher than the lowest end of the working end face of the left pawl 2.3 in the pusher engagement box assembly and lower than the lowest end of the working end face of the right pawl 2.4. The inner conveyor chain pusher 5.1 and the outer conveyor chain pusher 8.1 alternately contact the working end face of the left claw 2.3 and drive the trolley 2 from right to left; In the adjacent outer conveyor chain 8 and inner conveyor chain 5, the distance between the outer conveyor chain pushers is equal, and the length of the outer conveyor chain 8 is an integer multiple of the distance between the outer conveyor chain pushers. The distance between the inner conveyor chain pushers is equal, and the length of the inner conveyor chain 5 is an integer multiple of the distance between the inner conveyor chain pushers. The ratio of the distance between the outer conveyor chain pushers to the distance between the inner conveyor chain pushers is equal to the ratio of the running speed of the outer conveyor chain 8 to the running speed of the inner conveyor chain 5. The distance between the outer conveyor chain pushers is the distance between adjacent outer conveyor chain pushers 8.1, and the distance between the inner conveyor chain pushers is the distance between adjacent inner conveyor chain pushers 5.1. The semi-engaged section 3.7 of the upper track drive section of the inner conveyor chain and the semi-engaged section 6.3 of the upper track tensioning section of the outer conveyor chain overlap in the front-to-back direction; A pusher engagement box assembly is installed on the inner and outer sides of the left end of the trolley 2, respectively, at the same height.

[0030] The working principle and process of Example 1 are as follows: An inner conveyor chain 5 is provided in the inner conveyor chain track, and an outer conveyor chain 8 is provided in the outer conveyor chain track. The inner conveyor chain 5 is driven by the inner conveyor chain drive sprocket 9, and the outer conveyor chain 8 is driven by the outer conveyor chain drive sprocket 10.

[0031] During the conveying process of trolley 2 from right to left, trolley 2 needs to be driven by the outer conveyor chain pusher 8.1 of the outer conveyor chain 8 instead of the inner conveyor chain pusher 5.1 of the inner conveyor chain 5. Since the distance between the outer conveyor chain pushers is equal in adjacent outer conveyor chains 8 and inner conveyor chains 5, and the length of the outer conveyor chain 8 is an integer multiple of the distance between the outer conveyor chain pushers, the distance between the inner conveyor chain pushers is equal, and the length of the inner conveyor chain 5 is an integer multiple of the distance between the inner conveyor chain pushers, the ratio of the distance between the outer conveyor chain pushers to the distance between the inner conveyor chain pushers is equal to the ratio of the running speed of the outer conveyor chain 8 to the running speed of the inner conveyor chain 5; this ensures that the relative positions of the outer conveyor chain pushers 8.1 and the inner conveyor chain pushers 5.1 are consistent in each cycle of adjacent outer conveyor chains 8 and inner conveyor chains 5.

[0032] If the running speed of the inner conveyor chain 5 is less than the running speed of the outer conveyor chain 8, when the inner conveyor chain pusher 5.1 of the pushing trolley 2 is in the fully engaged section 3.5 of the upper track of the inner conveyor chain, the inner conveyor chain pusher 5.1 and the corresponding pusher engagement box assembly are in a fully engaged state. The outer conveyor chain pusher 8.1, which then follows the inner conveyor chain pusher 5.1, is in the tensioning section separation section 6.1 of the upper track of the outer conveyor chain. The highest point of the outer conveyor chain pusher 8.1 is located below the lowest point of the working end face of the corresponding left pawl 2.3 and right pawl 2.4. The outer conveyor chain pusher 8.1 and the corresponding pusher engagement box assembly are in a separated state. Figure 18 As shown, the trolley 2 cannot be pushed by the inner conveyor chain pusher 5.1 and is instead pushed by the outer conveyor chain pusher 8.1. When the inner conveyor chain pusher 5.1 pushing the trolley 2 passes through the transition section 3.6 of the inner conveyor chain upper track drive section and enters the half-engagement section 3.7 of the inner conveyor chain upper track drive section, the inner conveyor chain pusher 5.1 descends, and the inner conveyor chain pusher 5.1 and the corresponding pusher engagement box assembly are in a half-engagement state. The outer conveyor chain pusher 8.1, which takes over from the inner conveyor chain pusher 5.1, passes through the first transition section 6.2 of the outer conveyor chain upper track tension section and enters the half-engagement section 6.3 of the outer conveyor chain upper track tension section. The outer conveyor chain pusher 8.1 rises, and the outer... The highest point of the side conveyor chain pusher 8.1 is higher than the lowest point of the working end face of the corresponding left pawl 2.3 and lower than the lowest point of the working end face of the corresponding right pawl 2.4. The outer conveyor chain pusher 8.1 moves to the left, passing the corresponding right pawl 2.4, and then slowly catches up with the corresponding left pawl 2.3. After the outer conveyor chain pusher 8.1 contacts the working end face of the corresponding left pawl 2.3, the trolley 2, previously pushed by the inner conveyor chain pusher 5.1, is now pushed by the outer conveyor chain pusher 8.1. The outer conveyor chain pusher 8.1 and the corresponding pusher engagement box assembly are in a semi-engaged state. Figure 17As shown. When the outer conveyor chain pusher 8.1 of the trolley 2 passes through the second transition section 6.4 of the tensioning section of the upper track of the outer conveyor chain and enters the full engagement section 6.5 of the upper track of the outer conveyor chain, the outer conveyor chain pusher 8.1 rises again. The highest point of the outer conveyor chain pusher 8.1 is higher than the lowest point of the working end face of the corresponding left pawl 2.3 and the lowest point of the working end face of the corresponding right pawl 2.4. The outer conveyor chain pusher 8.1 and the corresponding pusher engagement box assembly are in a fully engaged state, as shown. Figure 16 As shown, the trolley 2 is pushed by the outer conveyor chain pusher 8.1 and runs to the left.

[0033] If the running speed of the inner conveyor chain 5 is greater than the running speed of the outer conveyor chain 8, when the inner conveyor chain pusher 5.1 of the pushing trolley 2 is in the fully engaged section 3.5 of the upper track of the inner conveyor chain, the inner conveyor chain pusher 5.1 and the corresponding pusher engagement box assembly are in a fully engaged state. The outer conveyor chain pusher 8.1, which is in contact with the inner conveyor chain pusher 5.1, is in the tensioning section separation section 6.1 of the upper track of the outer conveyor chain. The highest point of the outer conveyor chain pusher 8.1 is located below the lowest point of the working end face of the corresponding left pawl 2.3 and right pawl 2.4. The outer conveyor chain pusher 8.1 and the corresponding pusher engagement box assembly are in a separated state. Figure 18As shown, the trolley 2 cannot be pushed by the inner conveyor chain pusher 5.1 and can instead be pushed by the outer conveyor chain pusher 8.1. When the inner conveyor chain pusher 5.1 of the trolley 2 passes through the transition section 3.6 of the upper inner conveyor chain drive section and enters the semi-engaged section 3.7 of the upper inner conveyor chain drive section, the inner conveyor chain pusher 5.1 descends, and the inner conveyor chain pusher 5.1 is in a semi-engaged state with the corresponding pusher engagement box assembly. The outer conveyor chain pusher 8.1, which then passes through the first transition section 6.2 of the upper outer conveyor chain tension section, enters the semi-engaged section 6.3 of the upper outer conveyor chain tension section. The outer conveyor chain pusher 8.1 rises, with its highest point higher than the lowest point of the working end face of the corresponding left pawl 2.3 and lower than the lowest point of the working end face of the corresponding right pawl 2.4. The left pawl 2.3 in the outer pusher engagement box assembly on the trolley 2, pushed by the inner conveyor chain pusher 5.1, then... As the left pawl 2.3 in the outer pusher head 8.1 passes the outer pusher head 8.1, its working end is blocked by the outer pusher head 8.1, causing it to rotate counterclockwise by a certain angle until it is horizontal. This continues until the inner pusher head 5.1 reaches the downward position of the inner pusher drive sprocket 9 and separates from the inner pusher head engagement box assembly. After the trolley 2 briefly loses power, the outer pusher head engagement box assembly is caught up by the outer pusher head 8.1. The outer pusher head 8.1 pushes the working end face of the left pawl 2.3 in the outer pusher head engagement box assembly, and enters the full engagement section 6.5 of the upper track of the outer conveyor chain. The outer pusher head 8.1 and the corresponding pusher head engagement box assembly are in full engagement. Figure 16 As shown, the trolley 2 is pushed by the outer conveyor chain pusher 8.1 and runs to the left, thereby realizing the same-beat zoned different-speed CPC conveyor chain drive of the trolley 2.

[0034] Example 2 The structure of this embodiment is basically the same as that of embodiment 1, except that: On the frame 1 and in the direction of travel of the trolley 2, there is a set of inner conveyor chain tracks and a set of outer conveyor chain tracks, with the outer conveyor chain tracks located to the right of the inner conveyor chain tracks. The semi-engaged section 3.3 of the tensioning section of the upper track of the inner conveyor chain overlaps with the semi-engaged section 6.7 of the driving section of the upper track of the outer conveyor chain in the front-back direction.

[0035] The working principle and process of Example 2 are as follows: An inner conveyor chain 5 is provided in the inner conveyor chain track, and an outer conveyor chain 8 is provided in the outer conveyor chain track. The inner conveyor chain 5 is driven by the inner conveyor chain drive sprocket 9, and the outer conveyor chain 8 is driven by the outer conveyor chain drive sprocket 10.

[0036] During the process of conveying the trolley 2 from right to left, the trolley 2 needs to be pushed by the outer conveyor chain pusher 8.1 of the outer conveyor chain 8 to be pushed by the inner conveyor chain pusher 5.1 of the inner conveyor chain 5.

[0037] If the running speed of the outer conveyor chain 8 is less than the running speed of the inner conveyor chain 5, when the outer conveyor chain pusher 8.1 of the trolley 2 is in the fully engaged section 6.5 of the upper track of the outer conveyor chain, the outer conveyor chain pusher 8.1 and the corresponding pusher engagement box assembly are in a fully engaged state. The inner conveyor chain pusher 5.1, which takes over from the outer conveyor chain pusher 8.1, is in the separating section 3.1 of the upper track of the tensioning section of the inner conveyor chain. The highest point of the inner conveyor chain pusher 5.1 is located below the lowest point of the working end face of the corresponding left pawl 2.3 and right pawl 2.4. The inner conveyor chain pusher 5.1 and the corresponding pusher engagement box assembly are in a separated state. Figure 21 As shown, the trolley 2 cannot be pushed by the outer conveyor chain pusher 8.1 and is instead pushed by the inner conveyor chain pusher 5.1. When the outer conveyor chain pusher 8.1 pushing the trolley 2 passes through the transition section 6.6 of the outer conveyor chain upper track drive section and enters the half-engagement section 6.7 of the outer conveyor chain upper track drive section, the outer conveyor chain pusher 8.1 descends, and the outer conveyor chain pusher 8.1 and the corresponding pusher engagement box assembly are in a half-engagement state. The outer conveyor chain pusher 8.1 that takes over the outer conveyor chain pusher 8.1 passes through the first transition section 3.2 of the inner conveyor chain upper track tension section and enters the half-engagement section 3.3 of the inner conveyor chain upper track tension section. The inner conveyor chain pusher 5.1 rises, and the inner... The highest point of the side conveyor chain pusher 5.1 is higher than the lowest point of the working end face of the corresponding left pawl 2.3 and lower than the lowest point of the working end face of the corresponding right pawl 2.4. The inner conveyor chain pusher 5.1 moves to the left, passing the corresponding right pawl 2.4, and then slowly catches up with the corresponding left pawl 2.3. After the inner conveyor chain pusher 5.1 contacts the working end face of the corresponding left pawl 2.3, the trolley 2, which was previously pushed by the outer conveyor chain pusher 8.1, is now pushed by the inner conveyor chain pusher 5.1. The inner conveyor chain pusher 5.1 and the corresponding pusher engagement box assembly are in a semi-engaged state. Figure 20As shown. When the inner conveyor chain pusher 5.1 of the trolley 2 passes through the second transition section 3.4 of the tensioning section of the upper inner conveyor chain track and enters the full engagement section 3.5 of the upper inner conveyor chain track, the inner conveyor chain pusher 5.1 rises again. The highest point of the inner conveyor chain pusher 5.1 is higher than the lowest point of the working end face of the corresponding left pawl 2.3 and the lowest point of the working end face of the corresponding right pawl 2.4. The inner conveyor chain pusher 5.1 and the corresponding pusher engagement box assembly are in a fully engaged state, as shown. Figure 19 As shown, the trolley 2 is pushed by the inner conveyor chain pusher 5.1 and runs to the left.

[0038] If the running speed of the outer conveyor chain 8 is greater than the running speed of the inner conveyor chain 5, when the outer conveyor chain pusher 8.1 of the pushing trolley 2 is within the fully engaged section 6.5 of the upper track of the outer conveyor chain, the outer conveyor chain pusher 8.1 and the corresponding pusher engagement box assembly are in a fully engaged state. The inner conveyor chain pusher 5.1, which takes over from the outer conveyor chain pusher 8.1, is within the separating section 3.1 of the upper track of the tensioning section of the inner conveyor chain. The highest point of the inner conveyor chain pusher 5.1 is located below the lowest point of the working end face of the corresponding left pawl 2.3 and right pawl 2.4. The inner conveyor chain pusher 5.1 and the corresponding pusher engagement box assembly are in a separated state. Figure 21As shown, the trolley 2 cannot be pushed by the outer conveyor chain pusher 8.1 and can instead be pushed by the inner conveyor chain pusher 5.1. When the outer conveyor chain pusher 8.1 of the trolley 2 passes through the transition section 6.6 of the upper track drive section of the outer conveyor chain and enters the semi-engaged section 6.7 of the upper track drive section of the outer conveyor chain, the outer conveyor chain pusher 8.1 descends, and the outer conveyor chain pusher 8.1 is in a semi-engaged state with the corresponding pusher engagement box assembly. The inner conveyor chain pusher 5.1, which takes over from the outer conveyor chain pusher 8.1, passes through the first transition section 3.2 of the tension section of the upper track of the inner conveyor chain and enters the semi-engaged section 3.3 of the tension section of the upper track of the inner conveyor chain. The inner conveyor chain pusher 5.1 rises, and its highest point is higher than the lowest point of the working end face of the corresponding left pawl 2.3 and lower than the lowest point of the working end face of the corresponding right pawl 2.4. The left pawl 2.3 in the inner pusher engagement box assembly on the trolley 2, pushed by the outer conveyor chain pusher 8.1, then... As the left pawl 2.3 in the inner pusher head 5.1 passes the inner pusher head 5.1, its working end is blocked by the inner pusher head 5.1, causing it to rotate counterclockwise by a certain angle until it is horizontal. This continues until the outer pusher head 8.1 reaches the downward position of the outer pusher drive sprocket 10 and separates from the inner pusher head engagement box assembly. After the trolley 2 briefly loses power, the inner pusher head engagement box assembly is caught up by the inner pusher head 5.1. The inner pusher head 5.1 pushes the working end face of the left pawl 2.3 in the outer pusher head engagement box assembly, and enters the fully engaged section 3.5 of the upper track of the inner conveyor chain. The inner pusher head 5.1 and the corresponding pusher head engagement box assembly are in full engagement. Figure 19 As shown, the trolley 2 is pushed by the inner conveyor chain pusher 5.1 and runs to the left, thereby realizing the same-beat zoned different-speed CPC conveyor chain drive of the trolley 2.

[0039] Example 3 The structure of this embodiment is basically the same as that of embodiment 1, except that: On the frame 1, in the direction of travel of the trolley 2, there are two or more sets of inner conveyor chain tracks and two or more sets of outer conveyor chain tracks. In the adjacent inner conveyor chain upper track 3 and outer conveyor chain upper track 6, the tension section semi-engaged section 3.3 of the inner conveyor chain upper track and the drive section semi-engaged section 6.7 of the outer conveyor chain upper track overlap in the front-back direction, and the drive section semi-engaged section 3.7 of the inner conveyor chain upper track and the tension section semi-engaged section 6.3 of the outer conveyor chain upper track overlap in the front-back direction.

[0040] The working principle of Example 3 combines the working principles of Example 1 and Example 2, and will not be repeated here.

[0041] In this invention, the prerequisite for zoned, variable-speed conveying is that the conveying is done at the same pace (the time interval between adjacent car bodies 100 reaching the same position is fixed); otherwise, rear-end collisions may occur due to the distance between adjacent trolleys 2 continuously increasing or decreasing. Therefore, in the adjacent outer conveyor chain 8 and inner conveyor chain 5, the distance between the outer conveyor chain pushers is equal, and the length of the outer conveyor chain 8 is an integer multiple of the distance between the outer conveyor chain pushers. Similarly, the distance between the inner conveyor chain pushers is equal, and the length of the inner conveyor chain 5 is an integer multiple of the distance between the inner conveyor chain pushers. The ratio of the distance between the outer and inner conveyor chain pushers is equal to the ratio of the running speed of the outer conveyor chain 8 to the running speed of the inner conveyor chain 5. This ensures that in each cycle (when each trolley 2 reaches the transfer point), the relative positions of the outer conveyor chain pushers 8.1 and 5.1 in the adjacent outer and inner conveyor chains 8 and 5 are consistent. To avoid cumulative errors in the pusher position caused by long-term continuous production, the drive devices of the inner conveyor chain drive sprocket 9 and the outer conveyor chain drive sprocket 10 can be equipped with synchronous speed encoders and use servo motors to precisely control the sprocket speed.

[0042] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalents can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications and equivalents should be covered within the scope of the claims of the present invention.
