Description

Technical Field

[0001] The present invention relates to the field of laser cutting, and in particular to a multi-layer material bin, a laser cutting production system and a loading and unloading method. Background Art

[0002] In the sheet metal processing process of the laser cutting industry, in order to meet the usage requirements and unmanned operation in a single shift or multiple shifts, multi-layer material conveying devices and automatic sheet metal loading and unloading devices are usually equipped. The multi-layer material conveying device requires that each layer cannot be blocked or interfered when the robot takes and puts materials, which requires that each layer can be driven separately.

[0003] In the prior art, a Chinese utility model patent with authorization announcement number CN217224127U discloses a plate loading warehouse, comprising a frame, a three-layer material rack is arranged on the frame, the material rack is movably arranged on the frame, the material rack comprises a load-bearing frame, a column and a positioning plate, the positioning plate is arranged at the edge of the load-bearing frame, a plurality of columns are sequentially arranged at intervals on the two side edges of the load-bearing frame, the load-bearing frame is used as an inlet for a plate material stack at the other side edge opposite to the positioning plate, the plate material stack is stacked above the load-bearing frame through a transfer bracket and positioned through the column and the positioning plate; the frame is provided with movable guide rails on both sides of the load-bearing frame, the load-bearing frame is provided with a guide wheel connected with a sliding connection, a transmission screw is penetrated in the load-bearing frame, the load-bearing frame is fixedly connected to a screw nut sleeved on the transmission screw, the transmission screw is connected to a driving motor through a driving rod, and the driving motor drives the load-bearing frame to move between a plate storage station and a plate loading station of the frame along the movable guide rail through the driving rod and the transmission screw.

[0004] In a cutting system that includes an exchangeable worktable laser cutting machine, the automatic loading and unloading device for plates is responsible for transferring the plate raw materials to the worktable of the laser cutting machine, and transferring the cut finished products to the finished product rack. When the above technical solution is adopted, different racks can be used to place raw materials and finished products respectively. When the finished products are shipped out of the warehouse, the whole stack of finished products is transferred with the help of a crane. Since the rack shipped out of the warehouse blocks other racks, raw materials cannot be loaded, causing loading to be suspended, which in turn suspends the operation of the cutting machine and makes it impossible to form continuous operation, affecting production efficiency. Summary of the invention

[0005] In order to solve the technical problem in the above-mentioned prior art that the multi-layer material rack cannot be loaded and the processing is interrupted because the finished product outgoing warehouse blocks other material racks on its layer during use, the present invention provides a multi-layer material bin, a laser cutting production system and a loading and unloading method, which can realize the simultaneous loading of raw materials and the outgoing warehouse of finished products, thereby ensuring continuous production and improving cutting efficiency.

[0006] In a first aspect, the present invention provides a multi-layer material bin to solve the above technical problems. The material bin includes a rack, on which a raw material rack and a finished product rack are movably arranged. The raw material rack and the finished product rack are both provided with at least two layers. The finished product rack can shuttle between two adjacent layers of the raw material racks. The raw material rack is connected to a feeding drive unit, and the finished product rack is connected to a discharging drive unit. Along the length direction of the rack, a transfer area, a temporary storage area, and a discharging area are sequentially arranged. The transfer area is used for raw material feeding and finished product discharging. The raw material rack and the finished product rack can pause in the temporary storage area. The discharging area is used for finished product discharging. The raw material rack can reciprocate between the transfer area and the temporary storage area, and the finished product rack can move between the transfer area, the temporary storage area, and the discharging area.

[0007] By dividing the rack into a raw material rack and a finished product rack, and respectively providing drive units for the raw material rack and the finished product rack, the present invention enables raw material feeding and finished product discharging to be carried out simultaneously at both ends of the rack, so that there is no spatial overlap between feeding and discharging, and the processing will not be paused due to finished product discharging, ensuring the continuity of processing and improving production efficiency. On the other hand, by additionally providing a finished product rack and enabling the finished product rack to shuttle between two layers of raw material racks, the utilization rate of the vertical space is increased, the capacity of the material bin is enlarged, the number of feeding times and the number of processing interruptions are reduced, and the processing efficiency is further improved.

[0008] Further, the feeding drive unit includes a plurality of feeding chain transmission components, which are horizontally arranged inside the rack. The number of the feeding chain transmission components is the same as that of the raw material racks. The feeding driving sprocket of the feeding chain transmission component is rotatably arranged in the transfer area, and the feeding driven sprocket of the feeding chain transmission component is rotatably arranged in the temporary storage area or the discharging area. The feeding chain of the feeding chain transmission component is connected to the corresponding raw material rack. The feeding driving sprocket is connected to the corresponding feeding transmission shaft through the corresponding first feeding transmission component. The feeding transmission shaft is connected to the corresponding feeding drive shaft through the corresponding feeding clutch. The plurality of feeding drive shafts are respectively connected to the feeding main shaft through the corresponding second feeding transmission components. The feeding main shaft is connected to a feeding motor.

[0009] Through the cooperation of the feeding clutch, the second feeding transmission component, and the first feeding transmission component, the present invention achieves the technical effect of driving multiple layers of raw material racks to move by one feeding motor, avoiding setting a driving motor for each layer of raw material rack, reducing the investment in power components and wiring, lowering the cost, simplifying the structure at the same time, and improving the use reliability of the present material bin.

[0010] Further, the outbound driving unit includes a plurality of outbound chain transmission components, which are horizontally arranged inside the rack. The outbound chain transmission components are arranged between adjacent two layers of the feeding chain transmission components. The number of the outbound chain transmission components is the same as that of the finished product racks. The outbound driving sprockets of the outbound chain transmission components are rotatably arranged in the outbound area, and the outbound driven sprockets of the outbound chain transmission components are rotatably arranged in the transfer area. The outbound chains of the outbound chain transmission components are connected to the corresponding finished product racks. The outbound driving sprockets are connected to the corresponding outbound drive shafts through the corresponding first outbound transmission components. The outbound drive shafts are connected to the corresponding outbound driving shafts through the corresponding outbound clutches. A plurality of the outbound driving shafts are respectively connected to the outbound main shaft through the corresponding second outbound transmission components. The outbound main shaft is connected to an outbound motor.

[0011] Through the cooperation of the outbound clutch, the second outbound transmission component and the first outbound transmission component, the present invention realizes the technical effect of driving the movement of multiple layers of finished product racks by one outbound motor, avoiding setting a driving motor for each layer of finished product racks, reducing the investment of power components and wiring, lowering the cost, simplifying the structure at the same time, and further improving the use reliability of the present storage bin.

[0012] Further, a plurality of the feeding chain transmission components are oppositely arranged on the rack. The two opposite feeding chain transmission components are respectively connected to both ends of the same raw material rack. The two groups of the first feeding transmission components and the two groups of the second feeding transmission components for driving the same raw material rack are symmetrically arranged on both sides of the feeding motor. A plurality of the outbound chain transmission components are oppositely arranged on the rack. The two opposite outbound chain transmission components are respectively connected to both ends of the same finished product rack. The two groups of the first outbound transmission components and the two groups of the second outbound transmission components for driving the same finished product rack are symmetrically arranged on both sides of the outbound motor.

[0013] By respectively arranging corresponding transmission components at both ends of the raw material rack and the finished product rack, the present invention can evenly disperse the power of the corresponding motor to both ends of the raw material rack and the finished product rack, avoiding skew caused by uneven stress during the movement of the raw material rack and the finished product rack, resulting in stuck movement.

[0014] Further, guide wheels are rotatably arranged at both ends of the raw material rack and the finished product rack. Guide beams are arranged at corresponding positions on the rack. Guide grooves are arranged on the guide beams. The guide wheels can move in the guide grooves.

[0015] Further, dust-proof brush strips are arranged at the openings of the guide grooves.

[0016] By arranging the dust-proof brush strips, the present invention can reduce the entry of dust into the guide grooves, ensuring smooth movement of the raw material rack and the finished product rack.

[0017] Furthermore, both the raw material rack and the finished product rack include a bottom plate. Along the moving direction, a plurality of blocking rods are vertically arranged on both the front and rear sides of the bottom plate.

[0018] In a second aspect, the present invention also provides a laser cutting production system, including a laser cutting machine. The laser cutting machine adopts an exchange platform laser cutting machine, and also includes the above-mentioned multi-layer material bin. The multi-layer material bin is arranged on one side of the laser cutting machine. A loading and unloading device is also arranged between the multi-layer material bin and the laser cutting machine. The loading and unloading device includes a support frame, and a moving seat is movably arranged on the support frame. The moving direction of the moving seat is perpendicular to the moving direction of the raw material rack or the finished product rack. The moving seat can move from the upper part of the platform of the laser cutting machine to the transfer area, and a grasping component is liftably arranged on the moving seat.

[0019] Furthermore, the grasping component includes an installation frame, and a fork module and a suction cup module are arranged on the installation frame. The fork module is used for transporting finished products, and the suction cup module is used for transporting raw materials.

[0020] In a third aspect, the present invention also provides a loading and unloading method for the above-mentioned laser cutting production system, including the following steps: During loading, the loading clutch corresponding to the raw material rack of the corresponding layer realizes power transmission, and the corresponding raw material rack moves a set distance, moving from the temporary storage area to the transfer area. At the same time, the loading clutches corresponding to the raw material racks of other layers disconnect the power transmission. After the material grasping component moves horizontally in place, it descends, grasps the raw materials and then ascends, and then moves horizontally to the upper part of the platform of the laser cutting machine, and places the raw materials on the platform. During unloading, the unloading clutch corresponding to the finished product rack of the corresponding layer realizes power transmission, and the corresponding finished product rack moves a set distance, moving from the temporary storage area or the transfer area to the unloading area for finished product unloading. At the same time, the unloading clutches corresponding to the finished product racks of other layers disconnect the power transmission; Raw material loading and finished product unloading can be carried out simultaneously, and at this time, the moving directions of the corresponding raw material rack and the corresponding finished product rack are opposite.

[0021] It can be seen from the above technical solutions that the present invention has the following advantages: The present invention provides a multi-layer material bin, a laser cutting production system and a loading and unloading method. By dividing the rack into a raw material rack and a finished product rack, and respectively arranging driving units on the raw material rack and the finished product rack, it is possible to perform loading and finished product outbound at both ends of the rack simultaneously, so that there is no spatial overlap between loading and outbound, and processing suspension will not be caused by the outbound of finished products, ensuring the continuity of processing and improving production efficiency. On the other hand, a finished product rack is additionally arranged and the finished product rack can shuttle between two layers of raw material racks, increasing the utilization rate of vertical space, enlarging the bin capacity, reducing the number of loading times and processing interruption times, and further improving processing efficiency; through the cooperation of the loading clutch, the second loading transmission component and the first loading transmission component, the technical effect of driving the multi-layer raw material rack to move by one loading motor is achieved, avoiding setting a driving motor for each layer of raw material rack, reducing the investment of power components and wiring, reducing costs, and at the same time simplifying the structure and improving the use reliability of this bin; through the cooperation of the outbound clutch, the second outbound transmission component and the first outbound transmission component, the technical effect of driving the multi-layer finished product rack to move by one outbound motor is achieved, avoiding setting a driving motor for each layer of finished product rack, reducing the investment of power components and wiring, reducing costs, and at the same time simplifying the structure and further improving the use reliability of this bin; by respectively arranging corresponding transmission components at both ends of the raw material rack and the finished product rack, the power of the corresponding motor can be evenly distributed to both ends of the raw material rack and the finished product rack, avoiding skewing caused by uneven force when the raw material rack and the finished product rack move, resulting in movement jamming; by setting dust-proof brush strips, the entry of dust into the guide groove can be reduced, ensuring smooth movement of the raw material rack and the finished product rack.

Detailed implementation mode

[0028] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent. Detailed implementation mode one As Figure 1 and Figure 2 shown, this specific implementation mode provides a multi-layer material bin, including a rack 1, on which a raw material rack 2 and a finished product rack 5 are horizontally movably arranged. The raw material rack 2 and the finished product rack 5 are both provided with at least two layers. The finished product rack 5 can shuttle between adjacent two layers of the raw material rack 2. The raw material rack 2 is connected to a loading drive unit 3, and the finished product rack 5 is connected to a shipping drive unit 4. Along the length direction of the rack 1, a transfer area 101, a temporary storage area 102, and a shipping area 103 are sequentially arranged. The transfer area 101 is used for raw material loading and finished product unloading. The raw material rack 2 and the finished product rack 5 can pause in the temporary storage area 102. The shipping area 103 is used for finished product shipping. The raw material rack 2 can reciprocate between the transfer area 101 and the temporary storage area 102, and the finished product rack 5 can move between the transfer area 101, the temporary storage area 102, and the shipping area 103.

[0030] In this specific embodiment, the rack 1 is divided into a raw material rack 2 and a finished product rack 5. The raw material rack 2 and the finished product rack 5 are respectively provided with corresponding driving units. And the rack 1 is divided into a transfer area 101, a temporary storage area 102 and a shipping area 103 according to functions, which enables feeding and finished product shipping to be carried out simultaneously at both ends of the rack 1, so that there is no spatial overlap between feeding and shipping, and the processing will not be suspended due to the finished product shipping occupying the feeding space, ensuring the continuity of processing and improving production efficiency. On the other hand, adding the finished product rack 5 and enabling the finished product rack 5 to shuttle between the two layers of the raw material rack 2 increases the bin capacity, reduces the number of raw material feeding times and processing interruption times, further improves the processing efficiency. And compared with the prior art where a separate feeding bin and a raw material bin are provided, it increases the utilization rate of the vertical space and reduces the occupation of the ground space, which is more conducive to the layout of the production line. Moreover, the feeding and shipping have the same connection position, which is convenient for using one up-and-down device for feeding and discharging, and reduces the working distance of the loading and unloading device 6, which is beneficial to improving the transfer efficiency.

[0031] To enable only one raw material rack 2 to move during feeding, a separate driving motor and transmission component can be set for each layer of the raw material rack 2. Only by controlling the rotation of the corresponding driving motor can the corresponding raw material rack 2 move between the temporary storage area 102 and the transfer area 101. In this specific embodiment, to reduce the investment in driving components and simplify the structure, such as Figures 1 to 3As shown, the feeding drive unit 3 includes a plurality of feeding chain drive assemblies 307. The feeding chain drive assemblies 307 are horizontally arranged inside the rack 1. The number of the feeding chain drive assemblies 307 is the same as that of the raw material racks 2. The feeding driving sprockets of the feeding chain drive assemblies 307 are rotatably arranged in the transfer area 101 through bearings and shafts. The feeding driven sprockets of the feeding chain drive assemblies 307 are rotatably arranged in the temporary storage area 102 or the outbound area 103 through bearings and shafts. In this specific embodiment, the feeding driven sprocket is arranged in the outbound area 103. The feeding chains of the feeding chain drive assemblies 307 are connected to the corresponding raw material racks 2. The feeding driving sprockets are connected to the corresponding feeding drive shafts 305 through the corresponding first feeding drive assemblies 308. The feeding drive shafts 305 are connected to the corresponding feeding driving shafts 306 through the corresponding feeding clutches 304. The plurality of feeding driving shafts 306 are respectively connected to the feeding main shaft 302 through the corresponding second feeding drive assemblies 303. The feeding main shaft 302 is connected to the feeding motor 301.

In this specific embodiment, both the first feeding drive assembly 308 and the second feeding drive assembly 303 adopt chain drive assemblies. The feeding clutch 304 can adopt a dry clutch or a wet clutch. In this specific embodiment, an electromagnetic clutch is adopted. When the electromagnetic clutch is energized, the feeding driving shaft 306 and the feeding drive shaft 305 are power-connected. The feeding motor 301 can drive the corresponding raw material rack 2 to move through the corresponding first feeding drive assembly 308. For the other raw material racks 2 that do not need to discharge materials, the corresponding electromagnetic clutches are de-energized, and the power cannot be transmitted from the feeding driving shaft to the feeding drive shaft 305, and the corresponding feeding driving shafts 306 rotate idly. In this specific embodiment, the feeding motor 301 and the second feeding drive assembly 303 are both arranged inside the rack 1, which can greatly reduce the space occupation. The feeding motor 301 is arranged on the ground through a mounting bracket. The output shaft of the feeding motor 301 is respectively connected to the corresponding feeding main shaft 302 through a coupling. The feeding main shaft 302 is arranged on the ground through a rotating bracket. A bearing is arranged inside the rotating bracket. The driving sprocket of the second feeding drive assembly 303 is arranged close to the rotating bracket. One end of the feeding driving shaft 306 is also provided with a rotating bracket. A bearing is arranged inside the rotating bracket. The other end of the feeding driving shaft 306 is connected to one end of the feeding drive shaft 305 through a clutch. The other end of the feeding drive shaft 305 is rotatably arranged on the rack 1 through a bearing. It can be seen that through the cooperation of the feeding clutch 304, the second feeding drive assembly 303 and the first feeding drive assembly 308, the technical effect of driving multiple layers of raw material racks 2 to move by one feeding motor 301 is achieved, avoiding setting a driving motor for each layer of raw material rack 2, reducing the investment of power components and wiring, reducing the cost, simplifying the structure at the same time, and improving the use reliability of this silo.

[0032] As Figures 1 to 3 shown, similarly, to reduce the number of drive motors on the finished product rack 5 and reduce wiring, the outbound drive unit 4 includes a plurality of outbound chain drive assemblies 407. The outbound chain drive assemblies 407 are horizontally arranged inside the rack 1. The outbound chain drive assemblies 407 are arranged between two adjacent upper feeding chain drive assemblies 307. The number of the outbound chain drive assemblies 407 is the same as that of the finished product racks 5.

The outbound driven sprockets of the outbound chain drive assemblies 407 are rotatably arranged in the transfer area 101 through bearings and shafts. The outbound chains of the outbound chain drive assemblies 407 are connected to the corresponding finished product racks 5.

The outbound drive shafts 406 are connected to the corresponding outbound driving shafts 404 through the corresponding outbound clutches 405. A plurality of the outbound driving shafts 404 are respectively connected to the outbound main shaft 402 through the corresponding second outbound drive assemblies 403.

In this specific embodiment, both the first outbound drive assemblies 408 and the second outbound drive assemblies 403 adopt chain drive assemblies. The outbound clutches 405 can adopt dry clutches or wet clutches. In this specific embodiment, electromagnetic clutches are adopted. When the electromagnetic clutches are electrified, the outbound driving shafts 404 and the outbound drive shafts 406 achieve power connection. The outbound motor 401 can drive the corresponding raw material rack 2 to move through the corresponding first outbound drive assembly 408. For other raw material racks 2 that do not need to discharge materials, the corresponding electromagnetic clutches are powered off, and the power cannot be transmitted from the outbound driving shaft to the outbound drive shaft 406, and the corresponding outbound driving shafts 404 rotate idly. In this specific embodiment, the outbound motor 401 and the second outbound drive assemblies 403 are both arranged inside the rack 1, which can greatly reduce the space occupation. The outbound motor 401 is arranged on the ground through a mounting bracket. The output shaft of the outbound motor 401 is respectively connected to the corresponding outbound main shaft 402 through a coupling. The outbound main shaft 402 is arranged on the ground through a rotating support. Bearings are arranged inside the rotating support.

The guide wheels 10 can move in the guide grooves; to reduce dust from entering the guide grooves, dust-proof brush strips are arranged at the openings of the guide grooves.

[0034] As Figure 1 shown in the figure, to prevent raw materials or finished products from slipping off the raw material rack 2 and the finished product rack 5 during movement, both the raw material rack 2 and the finished product rack 5 include a bottom plate 9. Guide wheels 10 are arranged at both ends of the bottom plate 9.

The moving seat drives the material grabbing component to move horizontally to the upper part of the platform, the lifting plate drives the material grabbing component to descend, the fork module 603 in the material grabbing component grabs the raw materials, the lifting plate rises, the moving seat drives the material grabbing component to move horizontally to the upper part of the transfer area 101, and the lifting plate descends, and the fork module 603 places the finished products on the finished product rack 5; The raw material loading and the finished product outgoing warehouse can be carried out simultaneously, and at this time, the corresponding raw material racks 2 and the corresponding finished product racks 5 move in opposite directions.

[0040] It can be understood that the raw material loading and the finished product outgoing warehouse can also be carried out at different times, which is determined according to the storage situation of the finished products in the multi-layer material warehouse. However, when it is necessary to carry out simultaneously, in this specific embodiment, the outgoing warehouse does not affect the raw material loading to the platform of the laser cutting machine 7 at all, and there is no need to interrupt the loading.

[0041] It can be seen from the above specific embodiments that the present invention has the following beneficial effects: 1. By dividing the material rack 1 into the raw material rack 2 and the finished product rack 5, and the raw material rack 2 and the finished product rack 5 are respectively provided with drive units, it can enable the loading and the finished product outgoing warehouse to be carried out simultaneously at both ends of the material rack 1, so that there is no spatial overlap between the loading and the outgoing warehouse, and the processing will not be paused due to the outgoing warehouse of the finished products, ensuring the continuity of the processing and improving the production efficiency. On the other hand, the finished product rack 5 is additionally provided and can shuttle between the two layers of the raw material racks 2, increasing the utilization rate of the vertical space, increasing the capacity of the material warehouse, reducing the number of loading times and the number of processing interruptions, and further improving the processing efficiency; 2. Through the cooperation of the feeding clutch 304, the second feeding transmission assembly 303 and the first feeding transmission assembly 308, the technical effect of driving the multi-layer raw material rack 2 to move by one feeding motor 301 is achieved, avoiding setting a driving motor for each layer of the raw material rack 2, reducing the investment in power components and wiring, reducing costs, simplifying the structure at the same time, and improving the reliability of use of this silo; 3. Through the cooperation of the out-of-store clutch 405, the second out-of-store transmission assembly 403 and the first out-of-store transmission assembly 408, the technical effect of driving the multi-layer finished product rack 5 to move by one out-of-store motor 401 is achieved, avoiding setting a driving motor for each layer of the finished product rack 5, reducing the investment in power components and wiring, reducing costs, simplifying the structure at the same time, and further improving the reliability of use of this silo; 4. By respectively arranging corresponding transmission assemblies at both ends of the raw material rack 2 and the finished product rack 5, the power of the corresponding motor can be evenly dispersed to both ends of the raw material rack 2 and the finished product rack 5, avoiding skewing caused by uneven force when the raw material rack 2 and the finished product rack 5 move, resulting in stuck movement; 5. By arranging dust-proof brush strips, the entry of dust into the guide grooves can be reduced, ensuring smooth movement of the raw material rack 2 and the finished product rack 5.
