Description

Technical Field

[0001] This invention relates to the field of laser welding, and in particular to an automatic feeding and welding device for ton barrel bases. Background Technology

[0002] A tonne container (BNB) is a bulk container and an essential tool for modern warehousing and transportation of liquid products. A BNB consists of an inner container and a metal frame. The metal frame has a metal base at the bottom, which is manufactured by welding rectangular steel pipes to four feet.

[0003] Currently, before welding the base and steel pipe using a welding device, multiple sets of robotic arms are needed to transport the four bases and one steel pipe to the welding station, where the welding device then performs the welding. Finally, the robotic arms transfer the finished ton container base to the station. However, using multiple sets of robotic arms is costly, difficult to coordinate and control, and requires a large overall footprint. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic feeding and welding device for the base of a ton container. This device can automatically feed the base and steel pipe. The feeding process uses only the hydraulic cylinder in the telescopic mechanism as the actuator, which is low in cost, easier to control, and the entire device occupies a small area.

[0005] The technical solution of this invention is an automatic feeding and welding device for ton container bases, used to weld the base feet and steel pipes into a base. The automatic feeding and welding device for ton container bases includes a support frame, a supporting conveying device, a feeding device, and a welding device. The supporting conveying device is horizontally arranged on the support frame. Two sets of feeding devices are symmetrically arranged about the supporting conveying device along the width direction. The feeding device includes two symmetrically distributed positioning frames, two sets of symmetrically distributed pushing components, a supporting component for the steel pipe, and a telescopic mechanism for driving the pushing component and the supporting component. The positioning frames and the telescopic mechanism are both arranged on the support frame. The positioning frames have a positioning cylinder portion for stacking the base feet. The positioning plate for positioning the corner of the stacked steel pipes and the connecting plate that integrally connects the positioning cylinder and the positioning plate are part of the telescopic mechanism. When the telescopic mechanism extends, the pushing component pushes the bottom foot of the stack forward to the welding station on the supporting conveyor. The supporting component releases its support for the steel pipe, and the bottom steel pipe falls onto the four feet at the welding station. The welding device is set on the positioning frame and can weld the steel pipe to the feet. When the telescopic mechanism retracts, the pushing component moves outward from the welded base, and the supporting component supports the adjacent steel pipe above the base. The supporting conveyor transports the base out from under the stacked steel pipes.

[0006] Preferably, the pushing assembly includes a guide plate horizontally arranged on the support frame, a push plate that pushes the bottom foot down onto the guide plate, a bracket that supports the bottom foot that has not fallen onto the guide plate, a connecting column arranged at the bottom of the bracket, and a first guide component arranged on the support frame. The top surface of the bracket is flat and flush with the top surface of the push plate. The connecting column is arranged on the moving end of the first guide component, and the push plate is arranged at the front end of the bracket.

[0007] Preferably, the supporting conveying device includes a conveyor belt mechanism and a support plate mounted on a support frame. The support plate is horizontally supported on the inner top surface of the conveyor belt of the conveyor belt mechanism, and the top surface of the guide plate is flush with the top surface of the conveyor belt.

[0008] Preferably, the guide assembly is inclined relative to the telescopic mechanism in the telescopic direction, and the connecting frame includes a connecting frame disposed at the moving end of the guide assembly, a sleeve disposed on the connecting frame, a slide rod slidably disposed on the sleeve, and a slide table disposed at the outer end of the slide rod.

[0009] Preferably, the telescopic mechanism includes a hydraulic cylinder mounted on a support frame, a movable frame mounted on the moving end of the hydraulic cylinder, a guide rod horizontally mounted on the movable frame, and a spring fitted on the guide rod. The slide is horizontally slidably mounted on the guide rod, and the two ends of the spring are respectively connected to the slide and the movable frame.

[0010] Preferably, the inner side of the push plate matches the outer side of the base, and the two ends of the push plate are flush with the two ends of the base. A mounting shaft is provided on the guide plate, and an "L"-shaped positioning component is rotatably mounted on the mounting shaft. The front end of the positioning component has a bent plate portion. A torsion spring fitted on the outer periphery of the mounting shaft is connected between the guide plate and the positioning component. A trigger component is provided on the bracket to push the positioning component to rotate so as to block the bent plate portion at one end of the push plate and the base on the same side.

[0011] Preferably, the material support assembly includes horizontally distributed pallets and a transmission assembly that drivesly connects the pallets and the moving frame. The bottom surface of the pallet is higher than the top of the welded base and lower than the middle of the adjacent steel pipe above the base. The pallet has an inclined surface that gradually slopes upwards in the direction away from the steel pipe.

[0012] Preferably, the welding device includes two sets of welding mechanisms symmetrically distributed on both sides of the width direction of the supporting conveying device. The welding mechanism includes a mounting plate set on the positioning frame, an electric push rod horizontally set on the mounting plate, a moving table set at the outer end of the electric push rod, and two sets of welding components symmetrically distributed about the moving table.

[0013] Preferably, the welding assembly includes a connecting plate mounted on a positioning frame, an arc-shaped slide rail three mounted on the bottom of the connecting plate, a slider three slidably mounted on the slide rail three, a laser welding head mounted on the slider three, and a connecting rod with its two ends hinged to the slider three and the moving table respectively.

[0014] Compared with existing technologies, this invention has the following beneficial technical effects: This invention utilizes the gravity of the base and the steel pipe itself to achieve automatic descent. The base, having fallen onto the guide plate, is pushed forward by a pushing assembly to the welding station on the conveyor belt, enabling automatic feeding of the base and steel pipe. The feeding process uses only the hydraulic cylinder in the telescopic mechanism as the actuator, resulting in low cost, easier control, and a small footprint for the entire device. After welding is completed, the remaining steel pipes above the base are lifted, detaching them from the base, allowing the base to be smoothly conveyed out by the supporting conveyor device.

[0017] Example 1: As Figures 1-8As shown in this embodiment, an automatic feeding and welding device for ton container bases is proposed, used to weld the base 100 and the steel pipe 200 into a base. The base 100 has an arc-shaped part and both ends are vertical surfaces, and the steel pipe 200 is a rounded rectangular tube. The automatic feeding and welding device for ton container bases includes a support frame 1, a supporting conveying device, a feeding device, and a welding device.

[0018] like Figure 1 and Figure 4 As shown, the supporting conveyor is horizontally mounted on the support frame 1. The supporting conveyor includes a conveyor belt mechanism 3 and a support plate 4 mounted on the support frame 1. The support plate 4 is horizontally supported on the inner top surface of the conveyor belt of the conveyor belt mechanism 3. When the conveyor belt rotates to contact the support plate 4, it can be in a horizontal state and can stably support the weight of the base 100 and the steel pipe 200.

[0019] like Figures 1-4 As shown, two sets of feeding devices are symmetrically arranged along the width direction of the supporting conveyor. The feeding device includes two symmetrically distributed positioning frames 5, two sets of symmetrically distributed pushing components, a supporting component for the steel pipe 200, and a telescopic mechanism for driving the pushing component and the supporting component. The positioning frames 5 and the telescopic mechanism are both mounted on the support frame 1. The positioning frame 5 has a positioning cylinder part 51 for stacking the base feet 100, a positioning plate part 53 for positioning the corner parts of the stacked steel pipes 200, and a connecting plate part 52 that integrally connects the positioning cylinder part 51 and the positioning plate part 53. The positioning cylinder part 51 is used to limit and guide the base feet 100 when they are stacked, so that the base feet 100 can be stacked neatly and fall one by one under their own weight. Two connecting plate sections 52 and two positioning plate sections 53 are symmetrically arranged. The two positioning plate sections 53 can limit the movement near one corner of the steel pipe 200. The four positioning frames 5 are distributed diagonally in a rectangle, which can stack four stacks of base feet 100 and one stack of steel pipes 200. The top of the positioning cylinder section 51 and the positioning plate section 53 both have inclined plates that slope upward and outward, which facilitates the feeding of base feet 100 and steel pipes 200 from the top. When the telescopic mechanism extends, the pushing component pushes the bottommost base foot 100 of the stack forward to the welding station on the supporting conveyor. The supporting component releases the support for the steel pipe 200, and the bottommost steel pipe 200 of the stack falls onto the four base feet 100 at the welding station due to its own weight, thereby realizing the automatic feeding of base feet 100 and steel pipes 200.

[0020] For feeding the foot 100, the pushing assembly includes a guide plate 2 horizontally mounted on the support frame 1, a push plate 65 that pushes the foot 100 down onto the guide plate 2, a bracket 64 that supports the foot 100 that has not fallen onto the guide plate 2, a connecting column 63 located at the bottom of the bracket 64, and a guide assembly 1 mounted on the support frame 1. The top surface of the bracket 64 is flat and flush with the top surface of the push plate 65, and the top surface of the guide plate 2 is flush with the top surface of the conveyor belt. Thus, the pushing assembly can push the foot 100 forward from the guide plate 2 onto the conveyor belt. The edge of the conveyor belt is slightly chamfered to prevent the edge of the conveyor belt from blocking the forward movement of the foot 100. The guide plate 2 has a channel through which the connecting post 63 passes. The width of the channel is smaller than the size of the foot 100, so that the foot 100 will not fall out of the channel. The guide assembly 1 includes a slide rail 61 and a slider 62 slidably mounted on the slide rail 61. The connecting post 63 is located on the moving end of the guide assembly 1, that is, on the slider 62. The push plate 65 is located at the front end of the bracket 64.

[0021] like Figure 2 and Figure 3 As shown, before the pusher plate 65 pushes the bottom foot 100 forward, the bottommost foot 100 of the stack is located on the guide plate 2. The pusher plate 65 pushes the bottommost foot 100 forward from the guide plate 2 to the welding station on the conveyor belt. The bracket 64 supports the remaining stacked feet 100 inside the positioning cylinder 51, and these feet 100 also generate a certain frictional resistance to the movement of the bracket 64. When the pusher plate 65 moves outward in the opposite direction, the pusher plate 65 moves to the outside of the positioning cylinder 51, causing the bottommost foot 100 of the stack to fall onto the guide plate 2, ready for the next pusher plate 65 to push the material forward.

[0022] The guide assembly is inclined relative to the telescopic mechanism because the steel pipe 200 is a rounded rectangular tube, and the base 100 is generally L-shaped with an arc-shaped part, which is suitable for feeding the base 100 along the inclined direction. Therefore, the inclined guide assembly can guide the movement direction of the bracket 64 and the push plate 65, so that the push plate 65 can fit against the base 100 to push the base 100 forward. The connecting frame includes a connecting frame 66 set at the moving end of the guide assembly, a sleeve 67 set on the connecting frame 66, a slide rod 68 slidably set on the sleeve 67, and a slide table 69 set at the outer end of the slide rod 68. The connecting frame is driven to move by the telescopic mechanism. When the connecting frame moves towards the direction of supporting the conveying device, the sleeve 67 slides on the slide rod 68, and the four push plates 65 can push the four bases 100 inward synchronously along the diagonal of the rectangle to the welding station.

[0023] The welding device is mounted on the positioning frame 5, which can weld the steel pipe 200 to the base 100. The four bases 100 are distributed under the four corners of the steel pipe 200. To improve the reliability of the base structure after welding, a groove is designed on the top of the base 100. The steel pipe 200 can fall into the groove to fit, which also plays a certain positioning role and prevents positional displacement during welding. When the telescopic mechanism retracts, the pushing component moves outward from the welded base, and the supporting component supports the adjacent steel pipe 200 above the base. The supporting component does not contact the base; the base only contacts the conveyor belt of the conveyor belt mechanism 3. The conveyor belt mechanism 3 transports the base out from under the stacked steel pipes 200. The supporting component does not interfere with the transport of the base.

[0024] The welding device includes two sets of welding mechanisms symmetrically distributed on both sides of the width of the supporting conveying device. Each welding mechanism includes a mounting plate 17 mounted on the positioning frame 5, an electric push rod 18 horizontally mounted on the mounting plate 17, a moving platform 19 located at the outer end of the electric push rod 18, and two sets of welding components symmetrically distributed about the moving platform 19. The extension and retraction of the electric push rod 18 allows the two sets of welding components to move simultaneously, enabling welding to be performed at different points of contact between the base 100 and the steel pipe 200, resulting in a more reliable weld.

[0025] like Figure 6 As shown, the welding assembly includes a connecting plate 23 mounted on the positioning frame 5, an arc-shaped slide rail 22 mounted at the bottom of the connecting plate 23, a slider 21 slidably mounted on the slide rail 22, a laser welding head 24 mounted on the slider 21, and a connecting rod 20 hinged at both ends to the slider 21 and the moving table 19, respectively. The electric push rod 18 is initially in an extended state. When welding the base 100 and the steel pipe 200 is required, the laser welding head 24 is activated, and the electric push rod 18 retracts at a set, slower speed. The moving table 19, through the connecting rod 20, drives the slider 21 to slide outwards. The slider 21 then drives the laser welding head 24 to move along an arc-shaped path. The laser welding head 24 performs laser welding on the arc-shaped portion where the base 100 contacts the steel pipe 200. After welding is completed, the laser welding head 24 is turned off, the electric push rod 18 extends, and the moving table 19 drives the laser welding heads 24 to slide towards each other through the connecting rod 20 and the slider 21, so that the two laser welding heads 24 can move to the outside of the base obtained by welding the base foot 100 and the steel pipe 200, that is, to one side of the width direction of the base. When the base is transported by the supporting conveyor device in the future, the laser welding heads 24 will not block the movement path of the base.

[0026] This embodiment enables automatic feeding of the base 100 and steel pipe 200. The feeding process uses only the hydraulic cylinder 7 in the telescopic mechanism as the actuator, resulting in low cost, easier control, and a small footprint for the entire device. This equipment can stack the base 100 and steel pipe 200 separately, utilizing their own weight to achieve automatic descent. The pushing assembly pushes the base 100, which has fallen onto the guide plate 2, forward to the welding station on the conveyor belt. Then, the support for the steel pipe 200 is released, and the bottommost steel pipe 200 automatically falls onto the four bases 100 at the welding station. The remaining steel pipes 200 above press the bottommost steel pipe 200 down onto the four bases 100, facilitating accurate laser welding of the base 100 and steel pipe 200 using the welding device to obtain the ton container base. After welding is completed, the remaining steel pipes 200 above the base are lifted up so that they are detached from the base, and the base can be smoothly transported out by the supporting conveyor device.

[0027] Example 2: Figures 1-8 As shown, this embodiment proposes an automatic feeding and welding device for ton barrel bases. Compared to Embodiment 1, in this embodiment, the telescopic mechanism includes a hydraulic cylinder 7 mounted on a support frame 1, a movable frame 8 mounted on the moving end of the hydraulic cylinder 7, a guide rod 9 horizontally mounted on the movable frame 8, and a spring 10 fitted on the guide rod 9. A slide table 69 is horizontally slidably mounted on the guide rod 9, and the two ends of the spring 10 are connected to the slide table 69 and the movable frame 8, respectively. When the hydraulic cylinder 7 pushes the movable frame 8 forward, the movable frame 8 drives the guide rod 9, the spring 10, and the slide table 69 to move forward, thereby allowing the push plate 65 to push forward the bottommost foot 100 of the stacked structure. When the push plate 65 pushes forward the bottom foot 100, the downward pressure of the other bottom feet 100 on the bottommost foot 100 creates a certain resistance to the push plate 65's forward push. The spring 10 is compressed by the slide table 69, but this does not prevent the push plate 65 from pushing the bottom foot 100 forward to the welding station. Then, the steel pipe 200 falls onto the bottom foot 100 at the welding station.

[0028] like Figures 2-5As shown, the inner side of the push plate 65 matches the outer side of the base 100, and both ends of the push plate 65 are flush with both ends of the base 100. A mounting shaft 26 is provided on the guide plate 2, and an "L"-shaped positioning member 25 is rotatably mounted on the mounting shaft 26. The front end of the positioning member 25 has a bent folded plate portion 251. A torsion spring 27, fitted around the outer periphery of the mounting shaft 26, connects the guide plate 2 and the positioning member 25. A trigger assembly is provided on the bracket 64 to push the positioning member 25 to rotate, thereby blocking the folded plate portion 251 at one end of the push plate 65 and the base 100 on the same side. The trigger assembly includes a fixing frame 29 located at the rear end of the bracket 64 and a push wheel 28 rotatably located at the end of the fixing frame 29, with the push wheel 28 facing the rear of the positioning member 25. As the fixed frame 29 moves forward with the bracket 64, the push wheel 28 pushes against the rear of the positioning member 25, causing the folding plate 251 to rotate along the movement path of the base 100 and the push plate 65, and the torsion spring 27 is twisted. When the push plate 65 and one end of the base 100 are blocked by the folding plate 251, it indicates that the base 100 has moved into position, that is, moved to the welding station. After the base 100 and the steel pipe 200 are welded, the push plate 65 moves outward, the push wheel 28 gradually disengages from the positioning member 25, and the torsion spring 27 drives the positioning member 25 to reverse and reset.

[0029] The material support assembly includes horizontally distributed pallets 16 and a transmission assembly that drives the pallets 16 and the moving frame 8. The transmission assembly includes a rack 11 mounted on the moving frame 8, a rack 13 mounted on the pallet 16, a gear 12 rotatably mounted on the support frame 1 and meshing between racks 11 and 13, and a guide assembly 2 mounted on the support frame 1 and horizontally guiding rack 13. The guide assembly 2 includes a slide rail 15 mounted on the support frame 1 and a slider 14 slidably mounted on the slide rail 15, with the slider 14 mounted on rack 13. When the hydraulic cylinder 7 extends, the moving frame 8 drives rack 11 forward, and rack 11 drives rack 13 outward via gear 12, horizontally guided by slider 14 and slide rail 15; rack 13 drives pallet 16 outward, and when pallet 16 disengages from the lowermost steel pipe 200, the steel pipe 200 falls onto the four feet 100 of the welding station below. The bottom surface of the pallet 16 is higher than the top of the welded base and lower than the middle of the adjacent steel pipe 200 above the base. The pallet 16 has an inclined surface that gradually slopes upward away from the steel pipe 200. When the hydraulic cylinder 7 retracts, the two pallets 16 on both sides of the width direction of the conveying device can smoothly extend inward between the base and the adjacent steel pipe 200 above without contacting the base. They can support the remaining steel pipes 200, separating the base from the remaining steel pipes 200 above, and preventing the pallet 16 itself and the remaining steel pipes 200 from interfering with the conveying of the base below.

[0030] This embodiment can use the positioning component 25 to position the feeding of the base 100, and can make the base 100 move to the welding station first, and then the steel pipe 200 fall onto the base 100 to realize sequential feeding; and after the ton barrel base is welded, the base can be separated from the other steel pipes 200 above by the pallet 16, and the welded base product can be smoothly transported out by the supporting conveyor device.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
