Description

Technical Field

[0001] The invention relates to stone cutting technology, in particular to a stone cutting device. Background Art

[0002] Stone cutting equipment is a type of stone cutting machinery, which is used to cut stone into strips of required size horizontally and vertically. Traditional stone cutting uses a single knife, which is extremely inefficient. Currently, single knives are generally replaced with multiple knives, which improves efficiency, but there are still major shortcomings.

[0003] At present, there are two main methods for cutting stone strips. One is to cut horizontally and vertically separately, which requires multiple loading and unloading operations, which is cumbersome and inefficient. The other is to cut horizontally and vertically in one flow, first cutting horizontally into several intermediate plates, then conveying, turning, flipping, and connecting the intermediate plates one by one, and then cutting vertically. Although it saves the operation of loading and unloading in the middle, the series of operations in the middle to achieve the turning cutting not only greatly lengthens the entire cutting production line, but also complicates the operation, and requires high matching accuracy. The production efficiency is still not ideal, which affects the production benefits. Summary of the invention

[0053] The case is further described in detail below in conjunction with specific implementation methods.

[0054] This case involves a stone cutting equipment, such as Figure 1-10 As shown, it includes a transverse conveying and slitting machine, a coupling transfer bearing conveyor 700 and a longitudinal conveying and slitting machine. The coupling transfer bearing conveyor 700 is arranged between the transverse conveying and slitting machine and the longitudinal conveying and slitting machine, and plays the role of an intermediate transfer bearing for disengagement or coupling transmission.

[0055] The transverse conveying and cutting machine comprises a transverse frame 100, a transverse conveying vehicle 200 and a transverse saw blade cutting assembly 300. The transverse frame 100 is provided with a transverse rail 11, and the transverse conveying vehicle 200 is movably mounted on the transverse rail 11 to realize transverse back and forth conveyance. The transverse saw blade cutting assembly 300 is suspended on the transverse frame 100 to perform transverse cutting on the stone material on the transverse conveying vehicle 200 below it.

[0056] The horizontal saw blade cutting assembly 300 can be an existing related saw blade cutting assembly, and one preferred method is to suspend the saw blade in a swing cutting manner. Specifically, the horizontal saw blade cutting assembly 300 includes a swing frame 31, a saw blade spindle box 32, and a saw blade drive assembly 33. The swing frame 31 is movably pivoted on the horizontal frame 100. A lifting cylinder group 34 is provided between the swing frame 31 and the horizontal frame 100 to drive the swing frame 31 to swing in coordination with the cutting operation. The saw blade spindle box 32 is installed on the swing frame 31 and driven by the saw blade drive assembly 33 to realize the saw blade rotation cutting operation.

[0057] The longitudinal conveying and slitting machine has the same structural design as the transverse conveying and slitting machine. The primary difference is the different conveying directions, which are vertical and horizontal. The longitudinal conveying and slitting machine includes a longitudinal frame 400, a longitudinal conveying vehicle 500 and a longitudinal saw blade cutting assembly 600. Similarly, a longitudinal rail 41 is provided on the longitudinal frame 400, and the longitudinal conveying vehicle 500 is movably mounted on the longitudinal rail 41 to realize longitudinal back and forth conveying. The longitudinal saw blade cutting assembly 600 is suspended on the longitudinal frame 400 to perform longitudinal cutting on the stone on the longitudinal conveying vehicle 500 below it. The longitudinal saw blade cutting assembly 600 is set and operated in the same way as the transverse saw blade cutting assembly 300. The longitudinal saw blade cutting assembly 600 mainly includes a swing frame 61, a saw blade spindle box 62, a saw blade drive assembly 63 and a lifting cylinder group 64. It should be noted here that the saw blade spindle box 32 / 62 can be a single spindle integral drive form, or a plurality of spindles can be driven separately.

[0058] The coupling type transfer conveyor 700 includes a transfer frame 71, a transfer roller group 72 and a transfer transmission assembly 73. The transfer roller group 72 is installed on the transfer frame 71 and driven by the transfer transmission assembly 73 for lateral transportation. The lateral transport vehicle 200 is provided with a vehicle roller group 211 for lateral transportation, and the longitudinal transport vehicle 500 is provided with a vehicle roller group 511 for longitudinal transportation. That is, the vehicle roller group 211 of the lateral transport vehicle 200, the transfer roller group 72, and the vehicle roller group 511 of the longitudinal transport vehicle 500 are coaxially transported.

[0059] The vehicle roller group 211 of the transverse conveyor 200 is connected to the vehicle transmission assembly 23, and the vehicle transmission assembly 23 drives the vehicle roller group 211 to roll to realize conveying. Similarly, the vehicle roller group 511 of the longitudinal conveyor 500 is connected to the vehicle transmission assembly 53, and the vehicle transmission assembly 53 drives the vehicle roller group 511 to roll to realize conveying. A coupling assembly 74 is provided between the vehicle transmission assembly 23 and the transfer bearing transmission assembly 73, and between the vehicle transmission assembly 53 and the transfer bearing transmission assembly 73, respectively, so that the vehicle transmission assembly 23 and the transfer bearing transmission assembly 73 can be separated from each other or combined with each other by means of the corresponding coupling assembly 74; similarly, the vehicle transmission assembly 53 and the transfer bearing transmission assembly 73 can be separated from each other or combined with each other by means of the corresponding coupling assembly 74. The coupling assembly 74 can be an existing related coupling device, and the coupling assembly 74 is divided into a first coupling part 741 and a second coupling part 742, which are respectively installed on the relevant transmission shafts of the vehicle-mounted transmission assembly 23 and the transfer bearing transmission assembly 73, and on the relevant transmission shafts of the vehicle-mounted transmission assembly 53 and the transfer bearing transmission assembly 73. The horizontal conveyor 200 and the longitudinal conveyor 500 do not have the power to automatically convey the stone slab group. The power is provided by the transfer bearing conveyor linkage, that is, it relies on the linkage with the transfer bearing conveyor.

[0060] The stone cutting equipment in this case realizes the high-efficiency horizontal and vertical flow cutting operation of stone. Taking the horizontal conveying cutting machine as the front end of the assembly line as an example (of course the direction can also be reversed), the operation steps are:

[0061] 1) The stone to be cut is fed to the transverse conveyor 200 of the transverse conveying and cutting machine. After the transverse conveyor 200 is transported to a set position on the transverse frame 100, the transverse saw blade cutting assembly 300 transversely cuts the stone to be cut on the transverse conveyor 200 into a stone slab group;

[0062] 2) Afterwards, the transverse conveyor 200 carries the transversely cut stone slab group and delivers it to the position, and with the help of the corresponding coupling assembly 74, the vehicle-mounted transmission assembly 23 of the transverse conveyor 200 and the transfer bearing transmission assembly 73 are automatically linked and combined;

[0063] 3) The transfer bearing transmission assembly 73 starts working, driving the transfer bearing roller group 72 to roll, and also driving the vehicle-mounted roller group 211 of the transverse conveyor 200 to roll synchronously, and the stone slab group is transported from the vehicle-mounted roller group 211 to the transfer bearing roller group 72; then the transverse conveyor 200 disengages the linkage and returns, and repeats the above operation; that is, the continuous and efficient flow operation of transverse cutting and conveying of stone is realized;

[0064] 4) The longitudinal conveyor 500 uses the corresponding coupling assembly 74 to automatically link the vehicle transmission assembly 53 and the transfer bearing transmission assembly 73. The transfer bearing transmission assembly 73 starts to work, driving the transfer bearing roller assembly 72 to roll, and also drives the vehicle roller assembly 511 of the longitudinal conveyor 500 to roll synchronously. The slab group received by the transfer bearing roller assembly 72 is transferred to the vehicle roller assembly 511 of the longitudinal conveyor 500; the longitudinal conveyor 500 flexibly turns and transports the slab group (from horizontal to longitudinal direction);

[0065] It should be noted here that step 3) and step 4) are operated independently of each other in the front and back steps, that is, the transverse conveyor 200 and the longitudinal conveyor 500 are linked with the coupling transfer conveyor 700 in turn. Such a design is conducive to the transverse conveyor 200 and the longitudinal conveyor 500 to perform their own independent conveying and cutting operations without affecting each other, without being restricted by each other and incurring waiting time, thereby improving efficiency.

[0066] Of course, step 3) and step 4) can also be performed simultaneously, that is, the vehicle-mounted transmission component 23 and the transfer bearing transmission component 73 are linked together, and the vehicle-mounted transmission component 53 and the transfer bearing transmission component 73 are also linked together, thereby, the vehicle-mounted roller group 211, the transfer bearing roller group 72 and the vehicle-mounted roller group 511 roll synchronously, and the slab group can be transferred to the vehicle-mounted roller group 511 in one step.

[0067] 5) The roller assembly 511 of the longitudinal conveyor 500 carries the stone slab assembly to move longitudinally. After moving to the set position, the longitudinal saw blade cutting assembly 300 cuts the stone slab assembly longitudinally into stone strips of specific required sizes. After that, the longitudinal conveyor 500 sends out the stone strips and repeats the above operation, that is, after the horizontal cutting of the stone is completed, the continuous longitudinal cutting and transportation are completed, which is a continuous and efficient flow operation.

[0068] In order to facilitate the saw blade cutting assembly to perform efficient and accurate cutting operations on the stone on the conveyor vehicle, and to avoid the saw blade cutting from possibly damaging the conveyor vehicle (mainly the roller assembly), the present case also proposes a preferred design scheme for the transverse conveyor vehicle 200 and the longitudinal conveyor vehicle 300.

[0069] Optimal solution, taking the horizontal transport vehicle 200 as an example

[0070] The transverse transport vehicle 200 includes an upper frame 21 and a lower frame 22 that are movably assembled with each other. The lower frame 22 is provided with a strip plate group 221, which is composed of a plurality of strip plates that are parallel to each other and spaced apart and arranged side by side. The bottom of the lower frame 22 is provided with a running wheel group 222, which serves as the running and transporting wheel of the transverse transport vehicle 200 and is mounted on the transverse rail 11 for running. The upper frame 21 is movably mounted on the lower frame 22. The upper frame 21 is provided with a vehicle-mounted roller group 211, which is composed of a plurality of rollers that are parallel to each other and spaced side by side. The plurality of rollers of the vehicle-mounted roller group 211 and the plurality of strips of the strip group 221 are staggered in the horizontal direction (preferably staggered one by one). In this way, when the height position of the upper frame 21 relative to the lower frame 22 is changed, the vehicle-mounted roller group 211 can be raised and lowered relative to the strip group 221, thereby realizing the relative height change adjustment of the two.

[0071] The scheme for changing the height position of the upper frame 21 relative to the lower frame 22 is that a support wheel group 212 is provided at the bottom of the upper frame 21, and the wheel travel direction of the support wheel group 212 and the running wheel group 222 are arranged in parallel, that is, the wheel axes of the support wheel group 212 and the running wheel group 222 are parallel to each other, so that during the movement and sliding of the running wheel group 222, the support wheel group 212 is also in a state of being able to slide. A support inclined surface group 12 is provided on the horizontal frame 100, close to the side where the coupling transfer conveyor 700 is located, and the purpose of the support inclined surface group 12 is to allow the support wheel group 212 to crawl on it, and to change the height of the support wheel group 212 by the slope of the inclined surface, so that the support wheel group 212 has a high and low support state, and finally realizes the vehicle-mounted roller group 211 to be higher or lower than the strip plate group 221. The adjustable lifting action.

[0072] Furthermore, the purpose of the support inclined plane group 12 is to allow the support wheel group 212 to crawl on it, and the extending direction of the inclined plane of the support inclined plane group 12 is the wheel direction of the support wheel group 212 (the direction of the transverse rail 11). In order to facilitate the support wheel group 212 to smoothly enter and exit the support inclined plane group 12, the corresponding matching surface of the support inclined plane group 12 and the matching supporting wheel group 212 are designed to be a first inclined plane, a second inclined plane and a high plane that are successively connected from low to high. The high plane is close to the side where the coupling transfer conveyor 700 is located, so that the transverse transport vehicle 200 can stay there steadily and perform the coupling and combination with the coupling transfer conveyor 700. The inclination of the first inclined plane is greater than the inclination of the second inclined plane. The crawling process of the support wheel group 212 is appropriately buffered by two inclined planes with different inclinations, thereby improving the stability and reliability of the overall transportation of the transverse transport vehicle 200.

[0073] In a preferred embodiment, four support wheel groups 212 are provided, each group includes a support rod 2121 and a support wheel 2122 , the support rod 2121 passes through the lower frame 22 and extends downward, and the support wheel 2122 is installed at the bottom of the support rod 2121 .

[0074] Thus, in step 1) of the above-mentioned operating principle, the transverse conveyor 200 receives the material at the front end, at which time the supporting wheel group 212 is in a naturally sunken state, and the upper frame 21 is directly placed on the lower frame 22 and supported by it. At this time, the vehicle-mounted roller group 211 is lower than the slat group 221, and the stone to be cut is supported by the slat group 221; after the transverse conveyor 200 is transported to the set position on the transverse frame 100, of course, the set position is in the position corresponding to the front of the coupling combination (i.e., the front position of the supporting ramp group 12), and the transverse saw blade cutting assembly 300 transversely cuts the stone to be cut on the transverse conveyor 200 into a stone slab group; during the cutting process, the stone is stably placed on the slat group 221 waiting for cutting, and the saw blade group correspondingly saws on the slat group 221, and the sunken vehicle-mounted roller group 211 can avoid the problem of the saw blade group possibly cutting it by mistake. The slat group 221 is preferably made of wooden slats, that is, it is composed of a plurality of wooden slats, which can be disassembled and fixed on the lower frame 22 one by one. Preferably, the lower frame 22 is integrally provided with a bottom plate group 223 composed of a plurality of supporting bottom plates arranged side by side at intervals, so as to facilitate the disassembly, fixation and replacement of the wooden slats one by one.

[0075] Afterwards, in step 2) of the above operating principle, the transverse transport vehicle 200 carries the transversely cut stone slab group and continues to transport it forward, and the supporting wheel group 212 touches the supporting ramp group 12 and crawls on it. When it crawls to the set high position (the high plane position of the supporting ramp group 12), the vehicle-mounted roller group 211 rises to be higher than the strip group 221, and takes over the stone slab group on the strip group 221; at this time, the transverse transport vehicle 200 is also transported to its place, and the rising vehicle-mounted transmission assembly 23 is at the coupling combination position. With the help of the corresponding coupling assembly 74, the vehicle-mounted transmission assembly 23 and the transfer bearing transmission assembly 73 of the transverse transport vehicle 200 are automatically linked and combined; then step 3) can be carried out, the vehicle-mounted roller group 211 and the transfer bearing roller group 72 are mutually connected and synchronized to realize the stone slab group transportation.

[0076] The preferred solution is that the longitudinal transport vehicle 500 has the same structural design concept as the transverse transport vehicle 200. The longitudinal transport vehicle 500 includes an upper frame 51 and a lower frame 52. The upper frame 51 is provided with a vehicle-mounted roller group 511, and the lower frame 52 is provided with a strip plate group 521 and a running wheel group 522. The structural coordination of each part is the same as the corresponding structural coordination of the transverse transport vehicle 200, and will not be described in detail here. The difference lies in the change of the transverse and longitudinal directions. The running wheel group 522 is set on the longitudinal rail 41 for longitudinal walking.

[0077] The scheme of changing the height position of the upper frame 51 relative to the lower frame 52 is similar to the horizontal transport vehicle 200. The bottom of the upper frame 51 is provided with a support wheel group 512, and the support wheel group 512 is arranged parallel to the wheel running direction of the running wheel group 522. A support inclined plane group 42 is arranged on the longitudinal frame 400, close to the side where the coupling transfer conveyor 700 is located. Similarly, the purpose of the support inclined plane group 42 is to allow the support wheel group 512 to crawl on it, and to change the height of the support wheel group 512 by the slope of the inclined plane, and finally realize the vehicle-mounted roller group 511 to be higher or lower than the strip plate group 521. Similarly, there are four groups of support wheel groups 512, each group includes a support rod 5121 and a support wheel 5122, which will not be repeated here. Similarly, the support inclined plane group 42 is designed with a first inclined plane, a second inclined plane and a high plane that are successively connected from low to high, and the high plane is close to the side where the coupling transfer conveyor 700 is located. For details, please refer to the similar description of the supporting inclined surface group 12 of the transverse transport vehicle 200.

[0078] Thus, in step 4) of the above-mentioned operating principle, the longitudinal transport vehicle 500 is at the front end of the longitudinal frame 400 (i.e., close to the side where the coupling transfer conveyor 700 is located), at which time the supporting wheel group 512 is on the high plane of the supporting inclined plane group 42, and the vehicle-mounted roller group 511 is higher than the slat group 521; and the longitudinal transport vehicle 500 is also at the coupling combination position, and with the help of the corresponding coupling assembly 74, the vehicle-mounted transmission assembly 53 and the transfer transmission assembly 73 are automatically linked and combined, and the transfer transmission assembly 73 starts working, driving the transfer roller group 72 to roll, and also driving the vehicle-mounted roller group 511 of the longitudinal transport vehicle 500 to roll synchronously, and the slab group received by the transfer roller group 72 is transferred to the vehicle-mounted roller group 511 of the longitudinal transport vehicle 500;

[0079] Afterwards, in step 5) of the above operating principle, the on-board roller group 511 of the longitudinal conveyor 500 carries the stone slab group and moves backward in the longitudinal direction. During the backward movement, the supporting wheel group 512 correspondingly crawls downward along the supporting inclined surface group 42. When it descends and separates from the supporting inclined surface group 42, the supporting wheel group 512 is in a natural sinking state, and the upper frame 51 is directly placed on the lower frame 52 and supported by it. At this time, the on-board roller group 511 is lower than the strip board group 521, and the stone slab group to be cut is transferred from the on-board roller group 511 to the strip board group 521 for support; after the longitudinal conveyor 500 continues to move backward to the set position, the longitudinal saw blade cutting assembly 600 cuts the stone slab group longitudinally into stone strip groups of specific required sizes.

[0080] The preferred solution is that in the step 5), after the longitudinal cutting is completed, the longitudinal conveyor 500 sends out the stone bar group and then moves back and forth to repeat the operation. Here, the longitudinal conveyor 500 sends out the stone bar group, and the scheme adopted is, first, after the longitudinal conveyor 500 completes the longitudinal cutting, it continues to transport backward, and the cut stone bar group is taken out by the relevant material taking device, and then the longitudinal conveyor 500 returns to repeat the operation. The second is that considering that the longitudinal conveyor 500 needs to return to the material receiving position at the front end, the delivery position of the stone bar group designed here can be corresponding to the material receiving position, and further the coupling conveying method can be uniformly adopted, so that the time for the longitudinal conveyor 500 to operate back and forth once can be shortened, and the efficiency is improved. Specifically, the stone cutting equipment also includes a coupling discharger, which is located at the rear position of the longitudinal conveying and cutting machine in the horizontal direction, and a coupling assembly is provided between the coupling discharger and the vehicle-mounted transmission assembly 53 of the longitudinal conveyor 500. In this way, when the longitudinal conveyor 500 returns to repeat step 4), the vehicle-mounted transmission assembly 53 and the transfer bearing transmission assembly 73 are linked together, and at the same time, the vehicle-mounted transmission assembly 53 is also linked together with the coupling discharger. The stone slab group received by the transfer bearing roller group 72 is transferred to the vehicle-mounted roller group 511 of the longitudinal conveyor 500. At the same time, the cut stone bar group on the vehicle-mounted roller group 511 can be synchronously sent to the coupling discharger. In this way, the longitudinal conveyor 500 can perform discharging and receiving operations at the same time, and production efficiency is further improved.

[0081] It should be noted here that the main purpose of setting up the transverse transport vehicle 200 and the longitudinal transport vehicle 500 is to design the steering to meet the needs of transverse and longitudinal cutting. From a structural point of view, the main difference lies in the different transport directions, which is mainly reflected in the different directional relationships between the running wheel group and the vehicle-mounted roller group. The wheel direction of the running wheel group 222 of the transverse transport vehicle 200 is set in the same direction as the transport direction of the vehicle-mounted roller group 211, that is, both are set horizontally. The wheel direction of the running wheel group 522 of the longitudinal transport vehicle 500 is set perpendicular to the transport direction of the vehicle-mounted roller group 511, so as to achieve the purpose of steering.

[0082] In a preferred solution, taking the transverse transport vehicle 200 as an example (the same is true for the longitudinal transport vehicle 500), the support wheel set 212 is arranged at the bottom of the upper frame 21 to stagger the wheel line position corresponding to the wheel travel direction of the travel wheel set 222. This ensures that the support wheel set 212 and the travel wheel set 222 can slide independently without interfering with each other, and is also conducive to the high and low climbing action of the support wheel set 212.

[0083] The preferred solution, taking the transverse conveyor 200 as an example (the longitudinal conveyor 500 is the same), the vehicle-mounted roller group 212 is connected to the vehicle-mounted transmission assembly 23, which includes a transmission main shaft 231 and a plurality of helical gear groups; the helical gear group includes a first helical gear 232 and a second helical gear 233 that mesh with each other. The first helical gears 232 of the plurality of helical gear groups are installed on the transmission main shaft 231 at intervals, and the ends of the transmission main shaft 231 are provided for the installation of the coupling assembly 74. The second helical gears 233 of the plurality of helical gear groups are installed on the roller shafts of the roller groups 212 in a one-to-one correspondence. Thus, the transmission main shaft 231 is rotated in conjunction with each other, and the roller group 212 can be driven to roll through the transmission cooperation of the first helical gear 232 and the second helical gear 233. The vehicle-mounted transmission assembly 53 of the longitudinal conveyor 500 similarly includes a transmission main shaft 531 and a plurality of helical gear groups; the helical gear group includes a first helical gear 532 and a second helical gear 533 that mesh with each other, and the structural connection is similar.

[0084] In a preferred embodiment, the transfer bearing transmission assembly 73 includes a transmission main shaft 731 and a plurality of helical gear sets; the helical gear sets include first helical gears 732 and second helical gears 733 that mesh with each other for transmission; the first helical gears 732 of the plurality of helical gear sets are installed on the transmission main shaft 731 at intervals, and the second helical gears 733 of the plurality of helical gear sets are installed on the roller shafts of the transfer bearing roller sets 72 in a one-to-one correspondence. The non-end positions of the transmission main shaft 731 are transmission-connected with a transfer bearing drive assembly 734, and the two end positions of the transmission main shaft 731 are respectively used for connection with the coupling assembly 74. In addition, the connection method of the transfer bearing drive assembly 734 is that the transmission main shaft 731 is composed of two shafts arranged in a line, the inner ends of the two shafts are transmission-connected with the transfer bearing drive assembly 74 through a transmission mechanism, and the outer ends of the two shafts are respectively connected to the coupling assembly 74.

[0085] The preferred solution is to take the lateral transport vehicle 200 as an example (the longitudinal transport vehicle 500 is the same), the lateral frame 100 is provided with a lateral drive assembly 13 for driving the lateral transport vehicle 200, and the lateral drive assembly 13 includes a drive motor 131, two transmission wheel groups 132 and a transmission belt; the drive motor 131 is connected to a transmission wheel group 132 for transmission, and the two transmission wheel groups 132 are arranged front and back along the conveying direction, and the transmission belt is wound around the two transmission wheel groups 132, and the bottom of the lateral transport vehicle 200 is connected with the transmission belt. In this way, the drive motor 131 drives, drives the transmission belt to drive, and finally drives the lateral transport vehicle 200 to transport. The longitudinal transport vehicle 500 is similar, and the longitudinal frame 400 is provided with a longitudinal drive assembly 43 for driving the longitudinal transport vehicle 500. The longitudinal drive assembly 43 includes a drive motor 431, two transmission wheel groups 432 and a transmission belt; and is connected and driven in the same way as the lateral drive assembly 13. The transmission belt can be a belt, a wire rope, a chain belt, etc.

[0086] The preferred solution is that since the slab group is composed of a number of vertical slabs stacked horizontally, in order to facilitate the placement of the slab group when the slab group is cut as a whole, so as to achieve the purpose of accurate and effective cutting. The longitudinal conveying and slitting machine 500 is also equipped with a limit assembly 800, which includes a limit block 81 and a limit cylinder 82; the limit block 81 is arranged on the upper position of the corresponding vehicle-mounted roller group 511 on the longitudinal conveying vehicle 500, and the limit cylinder 82 is arranged on the longitudinal frame 100. The limit block 81 and the limit cylinder 82 are mutually matched and limited along the longitudinal front and back. In this way, when the longitudinal conveying vehicle 500 carries the slab group and transports it backward to the position to be cut, before cutting, the limit cylinder 82 first extends forward to cooperate with the limit block 81 to realize the front and rear tightening limit of the slab group between the two, and then the longitudinal cutting is performed.

[0087] The preferred solution is that after the stone is cut horizontally, there are gaps between the slabs of the slab group, in order to facilitate its transportation and subsequent longitudinal cutting operations. The coupling transfer conveyor 700 also includes a sorting component 75, which has two groups of tightening cylinder groups. The two groups of tightening cylinder groups are arranged above the transfer roller group 72 and are arranged opposite to each other in a direction perpendicular to the roller conveying direction. Therefore, after the transfer roller group 72 receives the incoming slab group, the two groups of tightening cylinder groups of the sorting component 75 first extend synchronously to merge and close the slabs of the slab group inward for sorting, and then transport them to the longitudinal transport vehicle 500.
