Description

Technical Field

[0001] This invention relates to the field of production line technology, and more specifically, to an automatic feeding sawing production line. Background Technology

[0002] In manufacturing, sawing production lines are common processing equipment, mainly used to saw pipes, strips, etc., to achieve the required length. In most existing sawing production lines, the material feeding area cannot be fed again during the sawing process, and it is necessary to wait for the sawing wheel to finish, resulting in long processing waiting time. At the same time, after sawing materials of different lengths, materials of different lengths are discharged from the same station, requiring manual secondary screening, resulting in low overall production line efficiency. Summary of the Invention

[0003] The problem addressed by this invention is how to improve the operating efficiency of a production line.

[0004] To address the aforementioned problems, this invention provides an automated feeding and sawing production line, comprising a pre-palletizing system, a material buffer box loading system, a feeding system, a discharging system, a sawing system, a unloading system, a first material buffer system, and a second material buffer system. The first and second material buffer systems are used to buffer materials of different length ranges. The pre-palletizing system, the feeding system, the sawing system, the discharging system, and the first material buffer system are arranged sequentially along a first direction. The material buffer box loading system is used to convey material buffer boxes to the second material buffer system, and the unloading system is used to load sawn materials into the material buffer boxes on the second material buffer system.

[0005] Optionally, the unloading system includes a frame and multiple sets of mechanical gripper assemblies spaced apart on the frame along the first direction. The mechanical gripper assemblies are used to move relative to the first material buffer system and the discharge system. The multiple sets of mechanical gripper assemblies cooperate with each other to grip the sawn material. The first material buffer system includes multiple first electric roller conveyors spaced apart along the first direction. The discharge system includes multiple first non-powered roller conveyors spaced apart along the first direction. Some of the first electric roller conveyors and some of the non-powered roller conveyors are located within the frame.

[0006] Optionally, each set of the mechanical gripper assemblies includes a drive member and two mechanical grippers arranged opposite each other along a second direction. The drive member is used to drive one of the mechanical grippers to move toward or away from the other mechanical gripper, and the second direction intersects the first direction.

[0007] Optionally, the discharge system further includes a first material clamping device and a first driving device, wherein the first driving device is used to drive the first material clamping device to move along the length direction of the first unpowered roller conveyor.

[0008] Optionally, the second material buffer system includes a transverse conveyor and a plurality of second electric roller conveyors spaced apart along the first direction, and the material buffer frame loading system includes a plurality of third electric roller conveyors spaced apart along the first direction. A portion of the transverse conveyor is placed within the frame, the feeding directions of the second and third electric roller conveyors are parallel, and the feeding direction of the transverse conveyor is perpendicular to the feeding directions of the second and third electric roller conveyors, respectively.

[0009] Optionally, the automatic feeding sawing production line also includes an automatic sensing device for sensing the distribution of the material buffer boxes on the transverse conveyor.

[0010] Optionally, the automatic feeding sawing production line further includes a third material buffer system. The third material buffer system includes a first pushing device, a moving trolley, a pallet, a first slide rail, a third unpowered roller conveyor, and a collection frame. The first slide rail extends along the width direction of the first unpowered roller conveyor. The first pushing device and the third unpowered roller conveyor are respectively located on both sides of the first slide rail away from the first unpowered roller conveyor. The moving trolley is slidably connected to the first slide rail. The pallet is disposed on the moving trolley. The collection frame is disposed on the third unpowered roller conveyor. The inlet of the collection frame faces the first pushing device. The moving trolley is used to move the pallet to the discharge port of the sawing system. The first pushing device is used to push the material on the pallet towards the collection frame along the length direction of the first unpowered roller conveyor.

[0011] Optionally, the automatic feeding sawing production line further includes a waste collection system, which includes a second chute and a waste frame. The second chute extends along the width direction of the first unpowered roller conveyor, and the waste frame is slidably connected to the second chute. The waste frame moves toward or away from the first unpowered roller conveyor. The third material buffer system further includes a second pushing device disposed on the moving trolley. The second pushing device is used to push the material on the pallet toward the waste frame along the width direction of the first unpowered roller conveyor.

[0012] Optionally, the pre-palletizing system includes a material alignment device, a material lifting plate, a material pushing device, and a plurality of fourth electric roller conveyors spaced apart along the first direction. The material alignment device is located at the feeding end of the feeding system. The material lifting plate is provided on the top of each of the fourth electric roller conveyors, and the material pushing device is provided on one side of at least one of the fourth electric roller conveyors in the length direction.

[0013] Optionally, the feeding system includes a second unpowered roller conveyor, a second material clamping device, and a second driving device, wherein the second driving device is used to drive the second material clamping device to move along the length direction of the second unpowered roller conveyor.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The pre-palletizing system, feeding system, sawing system, discharging system, and first material buffer system are arranged sequentially along a first direction. The pre-palletizing system can pre-palletize materials in the feeding area while sawing, and can immediately convey materials after the sawing of this round of materials is completed, achieving seamless connection of material sawing and thus shortening processing waiting time. The feeding system can transport the palletized materials to the sawing system for sawing, and the discharging system can convey the sawn materials toward the first material buffer system. Since the first material buffer system and the second material buffer system are used to buffer materials of different length ranges, when the length of the sawn materials meets the requirements of the first material buffer system... When the length of the material meets the requirements of the second material buffer system, the sawn material is directly buffered onto the first material buffer system. When the length of the sawn material meets the requirements of the second material buffer system, the first material buffer system stops working, and the unloading system is used to load the sawn material into the material buffer box on the second material buffer system. In this way, no manual secondary screening is required, which improves screening efficiency. At the same time, the material buffer box loading system is used to transport the material buffer boxes to the second material buffer system, enabling the second material buffer system to work continuously and reducing the waiting time for changing boxes. Ultimately, this improves the overall operating efficiency of the automatic feeding sawing production line. Attached Figure Description

[0030] It should also be noted that the meanings of the aforementioned Z-axis, X-axis and Y-axis are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0031] like Figure 1 , 2 As shown, the automatic feeding and sawing production line of this invention includes a pre-palletizing system 1, a material buffer box loading system 2, a feeding system 3, a discharge system 4, a sawing system 5, a unloading system 6, a first material buffer system 7, and a second material buffer system 8. The first material buffer system 7 and the second material buffer system 8 are used to buffer materials of different length ranges. The pre-palletizing system 1, the feeding system 3, the sawing system 5, the discharge system 4, and the first material buffer system 7 are arranged sequentially along a first direction. The material buffer box loading system 2 is used to convey the material buffer box to the second material buffer system 8, and the unloading system 6 is used to load the sawn materials into the material buffer box on the second material buffer system 8.

[0032] In this embodiment, the pre-palletizing system 1 can pre-palletize various rectangular tubes, channel steel, angle steel and H-beams, and the material length cached by the first material buffering system 7 is greater than the material length cached by the second material buffering system 8.

[0033] like Figure 1 , 2As shown, the first direction is the direction of the Y-axis. Along the direction of the Y-axis, the pre-palletizing system 1, feeding system 3, sawing system 5, discharging system 4 and the first material buffer system 7 are arranged in sequence. The five can be regarded as a straight line layout. The upper part system 2 of the material buffer frame is located to the left of the feeding system 3. The lower part system 6 is located at the junction of the discharging system 4 and the first material buffer system 7. Part of the second material buffer system 8 is located at the junction of the discharging system 4 and the first material buffer system 7 and cooperates with the lower part system 6. The other part is located to the right of the first material buffer system 7.

[0034] In this way, the pre-palletizing system 1 can pre-palletize materials in the feeding area while sawing, and can immediately convey materials after the sawing of this round of materials is completed, realizing seamless connection of material sawing and thus shortening the processing waiting time. Since the first material buffer system 7 and the second material buffer system 8 are used to buffer materials of different length ranges, when the length of the sawn material meets the length requirement of the first material buffer system 7, the sawn material is directly buffered on the first material buffer system 7. When the length of the sawn material meets the length requirement of the second material buffer system 8, the first material buffer system 7 does not work, and the unloading system 6 is used to load the sawn material into the material buffer frame on the second material buffer system 8. In this way, no manual secondary screening is required, improving screening efficiency. At the same time, the material buffer frame loading system 2 is used to convey the material buffer frame to the second material buffer system 8, realizing the continuous operation of the second material buffer system 8, reducing the waiting time for changing frames, and ultimately improving the overall operating efficiency of the automatic feeding sawing production line.

[0035] Optionally, the unloading system 6 includes a frame 61 and multiple sets of mechanical gripper assemblies 62 spaced apart on the frame 61 along a first direction. The mechanical gripper assemblies 62 are used to move relative to the first material buffer system 7 and the unloading system 4. The multiple sets of mechanical gripper assemblies 62 cooperate with each other to grip the sawn material. The first material buffer system 7 includes multiple first electric roller conveyors 71 spaced apart along the first direction. The unloading system 4 includes multiple first non-powered roller conveyors 41 spaced apart along the first direction. Some of the first electric roller conveyors 71 and some of the non-powered roller conveyors are located within the frame 61.

[0036] In this embodiment, the unloading system 6 mainly includes two parts, namely the frame 61 and the mechanical gripper assembly 62, such as... Figure 1 , 2As shown in Figure 3, the frame 61 includes a top frame 611 and legs 612. The top frame 611 includes two horizontal beams 6111 perpendicular to the Y-axis and two vertical beams 6112 parallel to the Y-axis. The two ends of the two horizontal beams 6111 support the two vertical beams 6112 respectively, and each end of the vertical beam 6112 is provided with a leg 612. The first material buffer system 7 includes multiple first electric roller conveyors 71, and the discharge system 4 includes multiple first non-powered roller conveyors 41. The multiple first electric roller conveyors 71 and the multiple first non-powered roller conveyors 41 are respectively arranged at intervals along the Y-axis. The top frame 611 has two crossbeams 6111 perpendicular to the Y-axis located on the first electric roller conveyors 71 and the first non-powered roller conveyors 41, respectively. Each of the two crossbeams 6111 is provided with a set of mechanical claw assemblies 62. That is, the two sets of mechanical claw assemblies 62 are arranged at intervals along the Y-axis. The mechanical claw assemblies 62 can move along the X-axis, Y-axis and Z-axis. Specifically, the two crossbeams 6111 of the top frame 611 are slidably connected to two longitudinal beams 6112 through guide rails. Each crossbeam 6111 is provided with a first drive. The first drive motor has a gear drive shaft connected to its output shaft. The longitudinal beam 6112 of the top frame 611 is equipped with a rack. The gear and rack mesh to drive the mechanical claw assembly 62 in the Y-axis direction. The two crossbeams 6111 have mounting plate assemblies on their opposite side walls. The mounting plate assemblies include a first plate and a second plate. The first plate is slidably mounted on the crossbeam 6111 via a guide rail extending along the X-axis direction and is driven by a telescopic cylinder to move the mechanical claw assembly 62 in the X-axis direction. The first plate is equipped with a guide rail extending along the Z-axis direction. The second plate is slidably mounted on the first plate and is driven by a telescopic cylinder to move the mechanical claw assembly 62 in the Z-axis direction.

[0037] In this way, when the two ends of the material being cut are located on the first electric roller conveyor 71 and the first unpowered roller conveyor 41 respectively, the mechanical claw assembly 62 on the two crossbeams 6111 can accurately grab the material at a fixed point by adjusting its position on the X-axis, Y-axis and Z-axis, and transport it to the material buffer box on the second material buffer system 8 for buffering.

[0038] In one embodiment, each mechanical claw assembly 62 includes a drive member 621 and two mechanical claws 622 disposed opposite to each other along a second direction. The drive member 621 is used to drive one of the mechanical claws 622 to move toward or away from the other mechanical claw 622. The second direction intersects with the first direction.

[0039] In this embodiment, the second direction is as follows: Figure 1 In the direction of the X-axis, the drive component 621 is either a pneumatic cylinder or an electric cylinder, such as... Figure 3As shown, the mechanical claw assembly 62 includes two L-shaped mechanical claws 622, which are arranged opposite each other along the X-axis direction, that is, the horizontal sections of the two mechanical claws 622 are arranged facing each other. The vertical section of one mechanical claw 622 is connected to the bottom end of the second plate of the mounting plate assembly, and the other mechanical claw 622 is slidably disposed on the lower end of the second plate via a guide rail. The driving member 621 is disposed on the second plate between the two mechanical claws 622 and is connected to one of the mechanical claws 622.

[0040] Thus, when it is necessary to increase the distance between the two mechanical claws 622, the drive unit 621 drives one of the mechanical claws 622 to move away from the other mechanical claw 622, and when it is necessary to decrease the distance between the two mechanical claws 622, the drive unit 621 drives one of the mechanical claws 622 to move towards the other mechanical claw 622.

[0041] Optionally, such as Figure 4 As shown, the discharge system 4 also includes a first material clamping device 43 and a first driving device 42. The first driving device 42 is used to drive the first material clamping device 43 to move along the length direction of the first unpowered roller conveyor 41.

[0042] In this embodiment, the first driving device 42 includes a second driving motor, a guide rail slider assembly, a gear, and a rack. The guide rail slider assembly includes a guide rail and a slider slidably disposed on the guide rail. The second driving motor is disposed on the slider, and the output shaft of the second driving motor is connected to the gear. The first unpowered roller conveyor 41 has connecting posts at both ends in the width direction (X-axis direction). The connecting posts are connected to at least one guide rail. The rack is disposed on the connecting posts and meshes with the gear for transmission. The guide rail and the rack are parallel to the feeding direction of the first unpowered roller conveyor 41. The first material clamping device 43 includes a movable frame, a first power device, a first clamping plate, and a second clamping plate. The movable frame includes a first upright, a second upright, and a connecting frame connecting the first upright and the second upright. The first upright and the second upright are respectively disposed on two sliders. The first power device is a cylinder or an electric cylinder. The first power device is disposed on the first upright and connected to the first clamping plate. The second clamping plate is disposed on the second upright and is disposed opposite to the first clamping plate.

[0043] Thus, when it is necessary to clamp the material, the first power unit drives the first clamping plate to move toward the second clamping plate, and after clamping the material, it drives the material to move along the length direction of the first unpowered roller conveyor 41; when it is necessary to release the material, the first power unit drives the first clamping plate to move away from the second clamping plate.

[0044] Furthermore, a guide rod is provided at the end of the first clamping plate facing the first upright, and the guide rod passes through the first upright. In this way, the movement of the first clamping plate in the Y-axis direction can be restricted.

[0045] Optionally, the second material buffer system 8 includes a transverse conveyor 81 and a plurality of second electric roller conveyors 82 spaced apart along the first direction. The material buffer frame loading system 2 includes a plurality of third electric roller conveyors 21 spaced apart along the first direction. Part of the transverse conveyor 81 is placed inside the frame 61. The feeding directions of the second electric roller conveyors 82 and the third electric roller conveyors 21 are parallel, and the feeding direction of the transverse conveyor 81 is perpendicular to the feeding directions of the second electric roller conveyors 82 and the third electric roller conveyors 21, respectively.

[0046] like Figure 1 As shown, multiple second electric roller conveyors 82 are spaced apart along the Y-axis direction; the transverse steel conveyor 81 includes two spaced chain conveyors 811, one end of which is located below the top frame 611. One chain conveyor 811 is located between the first electric roller conveyor 71 and the first unpowered roller conveyor 41, and the other chain conveyor 811 is located between two adjacent first electric roller conveyors 71. The conveying direction of the chain conveyor 811 is parallel to the X-axis direction; the material buffer box loading system 2 includes multiple third electric roller conveyors 21 spaced apart along the first direction. The feeding direction of the third electric roller conveyor 21 is parallel to the Y-axis direction. The multiple second electric roller conveyors 82 and the multiple third electric roller conveyors 21 are located on both sides of the transverse steel conveyor 81 in the Y-axis direction and are staggered.

[0047] In this way, the transverse conveyor 81, the second electric roller conveyor 82, and the third electric roller conveyor 21 form a layout similar to an inverted Z-shape, making efficient use of space. During operation, the material buffer boxes on the multiple third electric roller conveyors 21 are conveyed along the Y-axis to the two chain conveyors 811. After the material is loaded, the two chain conveyors 811 work together to convey the material buffer boxes along the X-axis to the second electric roller conveyor 82.

[0048] In other embodiments, a plurality of second electric roller conveyors 82 and a plurality of third electric roller conveyors 21 may be located on the same side of the transverse steel conveyor 81 in the Y-axis direction and arranged in parallel.

[0049] Optionally, the automatic feeding sawing production line also includes an automatic sensing device for sensing the distribution of material buffer boxes on the transverse conveyor 81.

[0050] In this embodiment, the automatic sensing device is an infrared sensor, which is positioned directly opposite the transverse conveyor steel machine 81. It can sense the distribution of material buffer boxes on the transverse conveyor steel machine 81. When the automatic sensing device senses that there are no material buffer boxes on the transverse conveyor steel machine 81, the empty box feeding system replenishes the material buffer boxes to the transverse conveyor steel machine 81.

[0051] Optionally, the automatic feeding sawing production line further includes a third material buffer system 9. The third material buffer system 9 includes a first pushing device 91, a moving trolley 92, a pallet 93, a first slide rail 94, a third unpowered roller conveyor 95, and a collection frame 96. The first slide rail 94 extends along the width direction of the first unpowered roller conveyor 41. The first pushing device 91 and the third unpowered roller conveyor 95 are respectively located on both sides of the first slide rail 94 away from the first unpowered roller conveyor 41. The moving trolley 92 is slidably connected to the first slide rail 94. The pallet 93 is located on the moving trolley 92. The collection frame 96 is located on the third unpowered roller conveyor 95. The inlet of the collection frame 96 faces the first pushing device 91. The moving trolley 92 is used to drive the pallet 93 to move to the discharge port of the sawing system 5. The first pushing device 91 is used to push the material on the pallet 93 towards the collection frame 96 along the length direction of the first unpowered roller conveyor 41.

[0052] In this embodiment, the material length cached by the third material caching system 9 is less than the material length cached by the second material caching system 8.

[0053] like Figure 1 , 7 As shown in Figure 8, the first slide 94 is along the width direction of the first unpowered roller conveyor 41 (e.g., ...). Figure 1 Extending along the X-axis, the first pushing device 91 and the third unpowered roller conveyor 95 are respectively located on the rear and front sides of the end of the first slide 94 away from the first unpowered roller conveyor 41. The moving trolley 92 is slidably connected to the first slide 94 via wheelsets. The pallet 93 is located at the end of the moving trolley 92 facing the first unpowered roller conveyor 41. The collection frame 96 is located on the third unpowered roller conveyor 95. The first pushing device 91 includes a fixed base 911, a first telescopic device 912, and a first push plate 913. The first telescopic device 912 is a cylinder or an electric cylinder, which is located on the fixed base 911 and connected to the first push plate 913. The lower end of the first push plate 913 is higher than the pallet 93 and faces the inlet of the collection frame 96. In this way, the moving trolley 92 is used to move the pallet 93 to the discharge port of the sawing system 5 to receive the material. Then the moving trolley 92 returns along the original route, and the pallet 93 carries the material between the first push plate 913 and the collection frame 96. Then the first pushing device 91 is used to push the material on the pallet 93 towards the collection frame 96 along the length direction of the first unpowered roller conveyor 41.

[0054] In this embodiment, the pallet 93 includes a section along the width direction of the first unpowered roller conveyor 41 (e.g., Figure 1Multiple veneers are spaced apart along the Y-axis. When the pallet 93 moves to the discharge port of the sawing system 5, each veneer is positioned between two adjacent rollers of the first unpowered roller conveyor 41, and the veneer is flush with the upper surface of the rollers of the first unpowered roller conveyor 41. That is, at the discharge port of the sawing system 5, the rollers and veneers are arranged sequentially along the Y-axis. This prevents the pallet 93 from obstructing the material movement onto the first unpowered roller conveyor 41.

[0055] Optionally, the automatic feeding sawing production line also includes a waste collection system 10, which includes a second slide 101 and a waste frame 102. The second slide 101 extends along the width direction of the first unpowered roller conveyor 41, and the waste frame 102 is slidably connected to the second slide 101. The waste frame 102 moves toward or away from the first unpowered roller conveyor 41. The third material buffer system 9 also includes a second pushing device 97 disposed on a moving trolley 92. The second pushing device 97 is used to push the material on the pallet 93 toward the waste frame 102 along the width direction of the first unpowered roller conveyor 41.

[0056] like Figure 9 As shown, the second slide 101 is along the width direction of the first unpowered roller conveyor 41 (e.g., Figure 1 Extending along the X-axis, the waste box 102 is slidably connected to the second slide rail 101 via wheelsets and is driven by a motor. The second pushing device 97 includes a second telescopic device 971 and a second push plate 972. The second telescopic device 971 is a cylinder or electric cylinder, mounted on the moving trolley 92 and connected to the second push plate 972. The lower end of the second push plate 972 is higher than the pallet 93 and faces the inlet of the waste box 102. Thus, the moving trolley 92 is used to move the pallet 93 to the discharge port of the sawing system 5 to receive the material, and then the second pushing device 97 is used to push the material on the pallet 93 toward the waste box 102 along the width direction of the first unpowered roller conveyor 41.

[0057] In this embodiment, the length of material buffered by the waste collection system 10 is less than the length of material buffered by the third material buffer system 9. For example... Figure 1 As shown, the automatic feeding sawing production line can buffer materials of four different length ranges, for example, materials less than 300mm, materials 300-600mm, materials 600-6000mm, and materials 6000-11900mm. Materials less than 300mm are collected by the waste collection system 10, materials 300-600mm are collected by the third material buffer system 9, materials 600-6000mm are collected by the second material buffer system 8, and materials 6000-11900mm are collected by the first material buffer system 7.

[0058] In this embodiment, the first slide 94 and the second slide 101 can be two separate slides, respectively for the moving trolley 92 and the waste box 102 to travel on; or they can be combined into one slide, simultaneously for the moving trolley 92 and the waste box 102 to travel on. There is no limitation here, and the choice can be made according to actual needs.

[0059] Optionally, the pre-palletizing system 1 includes a material alignment device 11, a material lifting plate 14, a material pushing device 12, and a plurality of fourth electric roller conveyors 13 spaced apart along a first direction. The material alignment device 11 is located at the feeding end of the feeding system 3. Each fourth electric roller conveyor 13 is provided with a material lifting plate 14 on its top. The material pushing device 12 and the fourth electric roller conveyor 13 are arranged in a one-to-one correspondence.

[0060] like Figure 1 As shown, the material alignment device 11 is installed at the feed end of the feeding system 3, and each fourth electric roller conveyor 13 is provided with a material lifting plate 14 at the top. At least one fourth electric roller conveyor 13 is provided with a material pushing device 12 on one side in the length direction.

[0061] In this embodiment, as Figure 6 As shown, the material alignment device 11 includes a support frame 111, a baffle 113, and a first lifting device 112. The baffle 113 is slidably mounted on the support frame 111 via a guide rail. The first lifting device 112 is a telescopic cylinder mounted on the support frame 111. The telescopic cylinder is connected to the baffle 113 and is used to drive the baffle 113 to move onto the feeding path of the fourth electric roller conveyor 13. Thus, during the material pre-stacking stage, the telescopic cylinder drives the baffle 113 to move upward along the Z-axis until the baffle 113 moves onto the feeding path of the fourth electric roller conveyor 13 to align the materials. When the pre-stacking system 1 conveys materials to the feeding system 3, the telescopic cylinder drives the baffle 113 to move downward along the Z-axis until the baffle 113 moves away from the feeding path of the fourth electric roller conveyor 13, preventing the baffle 113 from obstructing the material movement.

[0062] In this embodiment, as Figure 6 As shown, the material lifting plate 14 includes a second lifting device and a pallet 93. The second lifting device is a telescopic cylinder, which is mounted on the fourth electric roller conveyor 13 and connected to the pallet 93. The second lifting device is used to drive the pallet 93 to rise and fall. In this way, when the second lifting device drives the pallet 93 to rise above the top of the fourth electric roller conveyor 13, it can avoid collision with the fourth electric roller conveyor 13 when lifting materials; when the fourth electric roller conveyor 13 needs to transport materials, the second lifting device drives the pallet 93 to fall to be flush with the rollers of the fourth electric roller conveyor 13.

[0063] In this embodiment, as Figure 6As shown, the material alignment device 12 includes a support 121, a second power unit 122, a first pusher block 123, and a second pusher block 124. The first support 121 includes a mounting beam 1211 and a support beam 1212 disposed at the lower end of the mounting beam 1211. The height of the mounting beam 1211 is lower than or equal to the height of the rollers of the fourth electric roller conveyor 13. The first pusher block 123 and the second pusher block 124 are sequentially disposed on the mounting beam 1211 along the width direction of the fourth electric roller conveyor 13 (X-axis direction in Figure X). The first pusher block 123 is slidably connected to the mounting beam 1211 via a guide rail. The second power unit 122 is a telescopic cylinder, which is disposed on the mounting beam 1211 and connected to the first pusher block 123. The second power unit 122 is used to drive the first pusher block 123 to move toward or away from the second pusher block 124. In this way, the alignment of materials in the X-axis direction can be achieved under the action of the first pusher block 123 and the second pusher block 124.

[0064] Optionally, such as Figure 5 As shown, the feeding system 3 includes a second unpowered roller conveyor 31, a second material clamping device 32, and a second driving device 33. The second driving device 33 is used to drive the second material clamping device 32 to move along the length direction of the second unpowered roller conveyor 31.

[0065] In this embodiment, the second drive device 33 includes a third drive motor and a ball screw. At least two connecting plates are provided at both ends of the width direction (X-axis direction) of the second unpowered roller conveyor 31. The screw of the ball screw passes through the connecting plate and is parallel to the feeding direction of the second unpowered roller conveyor 31. The third drive motor is disposed on the second unpowered roller conveyor 31 and connected to the screw of the ball screw.

[0066] The second material clamping device 32 has the same structure as the first material clamping device 43 described above, so it will not be described again here. In the second material clamping device 32, its first and second uprights are threadedly connected to the moving block of the ball screw. In this way, the feeding system 3 and the discharging system 4 cooperate to achieve long-distance one-time precise positioning processing.

[0067] Optionally, the sawing system 5 includes a gantry saw, which is located between the feeding system 3 and the discharge system 4, and is used to saw the material. It is an existing mature product, so it will not be described in detail here.
