[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] See also Figures 1 to 8 The utility model provides a linear shuttle multi-station cutting production line, which is installed on a mounting base 6, and the mounting base 6 can be the ground, a platform, etc. The linear shuttle multi-station cutting production line has a plurality of cutting stations, and the plurality of cutting stations are arranged along a straight line at intervals.

[0029] It should be noted that, in this article, multiple cutting stations means that the number of cutting stations is two or more, and the number can be configured accordingly according to actual needs.

[0030] The utility model comprises a linearly arranged shuttle type multi-station cutting production line including: a conveyor line 1 arranged along a plurality of cutting stations, the conveyor line 1 being used to convey a pallet 2 loaded with materials to be cut to any cutting station. A cutting machine 3 and an elevator 4 are arranged at each cutting station of the cutting production line, the elevator 4 being used to lift the pallet 2 at the cutting station on the conveyor line 1 upwards, so that the cutting machine 3 at the corresponding cutting station can cut the materials.

[0031] Among them, when the pallet 2 on the upstream cutting station is lifted by the corresponding elevator 4, the pallet 2 leaves the conveyor line 1, so that the section of the conveyor line 1 at the upstream cutting station is vacated, and the conveyor line 1 can convey the next pallet 2 through the upstream cutting station to the downstream cutting station, so that the cutting machine 3 at the downstream cutting station does not need to wait for the upstream cutting machine 3 to finish working, and can cut the material on another pallet 2. In this way, only one production line is used to realize that multiple cutting machines 3 work simultaneously at their respective cutting stations, which greatly improves efficiency, saves space, reduces equipment costs, and optimizes the cutting production line structure. In addition, multiple cutting machines 3 can cut the required shape and size on the material according to different programs and parameters set by each of them to meet different cutting requirements, and are more practical.

[0032] It should be noted that the upstream and downstream in this article are based on the conveying direction of the conveyor line 1.

[0033] like Figure 1 As shown, the installation base 6 is provided with a trough along the conveying direction, the conveyor line 1 and the elevator 4 are fixedly installed in the trough, and the cutting machine 3 is mounted on both sides of the installation base 6 outside the trough. This installation method can further optimize the installation layout of the cutting production line and is more conducive to cutting and slag cleaning.

[0034] In addition, if Figure 2 and Figure 3 As shown, the utility model linearly arranged shuttle multi-station cutting production line also includes a plurality of slag collecting devices 5, which are arranged one by one on a plurality of cutting stations, and the slag collecting devices 5 are located directly below the tray 2 transported to the corresponding cutting station, and are used to receive the slag dropped when the cutting machine 3 cuts the material. The elevator 4 located at the same cutting station is connected to the slag collecting device 5, and the elevator 4 is used to drive the slag collecting device 5 to do lifting and lowering movements, and during the lifting and lowering movements of the slag collecting device 5, the elevator 4 can also drive the tray 2 on the cutting station to do lifting and lowering movements.

[0035] Furthermore, a plurality of grid plates are arranged at intervals on the tray 2 , and grid holes are provided between two adjacent grid plates. The grid holes are used to allow slag generated when the cutting machine 3 cuts the material to fall downward onto the slag receiving device 5 .

[0036] Optionally, the lift 4 can be any one of a screw lift, a worm gear lift, a rack and pinion lift, a screw lift, and a hydraulic lift. Figure 7As shown, in this embodiment, the elevator 4 is a screw elevator, and each cutting station is provided with multiple elevators 4, which are evenly and symmetrically distributed along the two outer sides of the conveyor line 1. The elevators 4 on the same side are linked by couplings and transmission shafts, and are driven by a reduction motor to move synchronously, which can meet the requirements of synchronous, stable, and reciprocating lifting of multiple units, and ensure the stability of the reciprocating lifting of the tray 2 and the slag receiving device 5.

[0037] Furthermore, each elevator 4 is provided with a lifting bracket 401, and the lifting bracket 401 is fixedly connected to the corresponding side of the slag receiving device 5. A support block 402 is provided on the top of the lifting bracket 401, which is higher than the top surface of the slag receiving device 5. The support block 402 is arranged opposite to the bottom surface of the tray 2 at the corresponding cutting station, so that the elevator 4 can lift the tray 2 through the support block 402 during the process of driving the slag receiving device 5 to lift through the lifting bracket 401. Among them, using the support block 402 to lift the tray 2 can also leave a gap between the tray 2 and the slag receiving device 5, which can be used to accommodate the fallen slag.

[0038] See also Figure 6 The conveyor line 1 includes a mounting bracket 101 fixed in the sink of the mounting base 6 along the conveying direction, a plurality of conveying rollers 102 and a driving device 103. The plurality of conveying rollers 102 are arranged in two rows, and the conveying rollers 102 in the two rows are respectively rotatably mounted on both sides of the mounting bracket 101 along the conveying direction. Figure 4 As shown, the width of the tray 2 is greater than the spacing between the two rows of conveying rollers 102, so that the tray 2 can be overlapped on the two rows of conveying rollers 102. The driving device 103 is a reduction motor, which is connected to a plurality of conveying rollers 102 through a sprocket-chain transmission assembly 104 (the chain is not shown in the figure), and the driving device 103 is used to drive the plurality of conveying rollers 102 to rotate synchronously to convey the tray 2.

[0039] In addition, a plurality of idler wheels 105 are installed on both sides of the mounting bracket 101 below the conveying roller 102 , and the winding path of the chain on the conveying roller 102 is changed by the plurality of idler wheels 105 to avoid the lifting bracket 401 .

[0040] See also Figure 4, the width of the slag receiving device 5 is smaller than the spacing between the two rows of conveying rollers 102, the slag receiving device 5 is arranged between the two rows of conveying rollers 102, and the slag receiving device 5 can be dropped below the plane where the two rows of conveying rollers 102 are located under the drive of the elevator 4. In this way, after the cutting of the material in the tray 2 lifted into place by the elevator 4 is completed, the elevator 4 drives the tray 2 and the slag receiving device 5 to drop synchronously through the lifting bracket 401 until the tray 2 is supported by the conveying rollers 102. In the following process, the tray 2 stops dropping because it is supported by the conveying rollers 102, and the slag receiving device 5 continues to drop below the plane where the two rows of conveying rollers 102 are located under the drive of the elevator 4, and the tray 2 is separated from the lifting bracket 401. At this time, the conveyor line 1 can convey the tray 2.

[0041] like Figure 7 As shown, in this embodiment, the slag receiving device 5 adopts a chain plate conveyor, the chain plate of the chain plate conveyor is used to receive the slag dropped when the cutting machine 3 cuts the material, and the chain plate conveyor can drive the chain plate to rotate to convey the slag, so that the slag falls from the conveying end to the external slag receiving hopper, and the slag is automatically cleared. Among them, the chain plate conveyor is an existing conventional technology.

[0042] Of course, in other embodiments of the present invention, the slag collecting device 5 can also be a slag collecting plate, which receives the slag dropped when the cutting machine 3 cuts the material. When the processing is completed and the production line is shut down, the slag on the slag plate can be cleaned manually.

[0043] Optionally, the cutting machine 3 may use a laser cutting head, a plasma cutting head, a flame cutting head, etc. The cutting machine 3 includes two tracks 301 arranged on both outer sides of the conveying line 1 along the conveying direction, a trolley 302 mounted on the two tracks 301, and a cutting head 303 installed on the trolley 302. The trolley 302 travels on the two tracks 301, and the cutting head 303 can move horizontally on the trolley 302 to process the required shape and size on the material. This is an existing conventional technology and will not be elaborated on in detail.

[0044] The working principle of the utility model linear arrangement shuttle multi-station cutting production line is as follows:

[0045] Initially, the slag receiving device 5 is driven by the elevator 4 and is located below the plane where the two rows of conveying rollers 102 are located.

[0046] Several pallets 2 are loaded with materials to be cut and are conveyed forward by the conveyor line 1. When the front pallet 2 reaches the upstream cutting station, the elevator 4 on the upstream cutting station drives the slag collecting device 5 to lift upward through the lifting bracket 401. When the support block 402 of the lifting bracket 401 rests against the bottom of the pallet 2, the elevator 4 starts to synchronously drive the pallet 2 to lift upward, and the cutting machine 3 of the upstream cutting station cuts the material on the pallet 2 that has been lifted into place according to the set program and parameters.

[0047] like Figure 8 As shown, when the pallet 2 that reaches the upstream cutting station is lifted up, the conveyor line 1 conveys the pallet 2 behind it through the upstream cutting station to the downstream cutting station, and the elevator 4 on the downstream cutting station drives the slag receiving device 5 to lift up through the lifting bracket 401. When the support block 402 of the lifting bracket 401 is against the bottom of the pallet 2, the elevator 4 starts to synchronously drive the pallet 2 to lift up, and the cutting machine 3 of the downstream cutting station cuts the material on the lifted pallet 2 according to the set program and parameters.

[0048] When the material cutting of the upstream cutting station is completed, the elevator 4 on the upstream cutting station drives the pallet 2 and the slag receiving device 5 to descend synchronously through the lifting bracket 401 until the pallet 2 is supported by the conveying roller 102. In the following process, the pallet 2 stops descending because it is supported by the conveying roller 102. The slag receiving device 5 continues to descend below the plane where the two rows of conveying rollers 102 are located under the drive of the elevator 4, and the pallet 2 is separated from the lifting bracket 401. At this time, the cutting machine 3 on the downstream cutting station is still processing, and the conveyor line 1 can transport the processed pallet 2 upstream through the downstream cutting station and continue to be transported forward to other stations. The cycle works in this way.

[0049] During this period, when the material on a cutting station is cut, and the slag collecting device 5 is driven by the elevator 4 to descend and return to its initial position, the slag collecting device 5, i.e., the chain conveyor, starts to drive the chain to rotate to convey the slag, so that the slag falls from the conveying end of the chain conveyor to the external slag collecting hopper, thereby realizing automatic slag cleaning.

[0050] It can be seen that the linearly arranged shuttle-type multi-station cutting production line of the utility model has a plurality of cutting stations arranged at intervals along a straight line, and each cutting station is provided with a cutting machine 3 and a lift 4, and a conveyor line 1 for conveying pallets 2 is also provided along the plurality of cutting stations. When the pallet 2 on the upstream cutting station is lifted by the corresponding lift 4, the conveyor line 1 can convey the next pallet 2 through the upstream cutting station to the downstream cutting station, so that the cutting machine 3 on the downstream cutting station can cut the material on another pallet 2 without waiting for the upstream cutting machine 3 to finish working. In this way, only one production line is used to realize that multiple cutting machines 3 can work simultaneously at their respective cutting stations, which greatly improves efficiency, saves space, reduces equipment costs, and optimizes the cutting production line structure. In addition, multiple cutting machines 3 can cut the required shapes and sizes on the materials according to different programs and parameters set by each of them to meet different cutting requirements, and are more practical.

However, the above description is only a preferred embodiment of the present invention.
