Description

Technical Field

[0001] The invention relates to the technical field of container processing, in particular to automatic welding of container sealing plates. Background Art

[0002] In the field of logistics and transportation, various containers are often needed. In the production process of containers, the two vertical beams of the container door must be sealed before assembly. When sealing, it is generally welded manually. According to the production process, there is a special door vertical pipe sealing station on the assembly line. Generally, multiple people are responsible for welding, slag removal, grinding and other work. In addition, manual welding is heavily dependent on the technical level of employees. Once the employees are temporarily replaced or the employees are tired, sleepy and in poor mental state, it will directly affect the product quality; frequent handling and relocation of door vertical pipes also have safety hazards of squeezing and smashing. At present, there are also special assembly lines for sealing door vertical pipes, but when sealing, it generally does not have a special mechanism to process the two ends of the door vertical pipe. It adopts the method of directly butt welding the sealing plate and the door vertical pipe for sealing. Although it can also perform sealing work, once the burrs, protrusions or impurities at both ends of the door vertical pipe are large, it will be sealed. There will be quality problems of leaking welding and cold welding, which seriously affect the product quality. Therefore, automatic welding of container sealing plates is proposed to address the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide automatic welding of container cover plates to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions: As an optional solution of the automatic welding of container cover plates of the present invention, wherein: the automatic welding of container cover plates comprises a material swinging machine, a material unloading machine and an equidistant conveyor; A stripping machine for driving the movement of the door vertical tube is installed on one side of the swinging machine, and an equidistant conveyor for equidistantly placing the door vertical tubes is arranged on one side of the stripping machine, a reciprocating feeder for driving the loading of the door vertical tubes is arranged on one side of the equidistant conveyor, a positioning device for limiting the door vertical tube is arranged on one side of the reciprocating feeder, a feeding machine for unloading the door vertical tube is arranged on one side of the positioning device, and multi-angle argon arc welding equipment for sealing both sides of the door vertical tube is arranged on both sides of the positioning device, and a welding machine frame for the argon arc welding equipment is arranged on the outer side of the multi-angle argon arc welding equipment; A second hydraulic rod is also fixedly connected to one side of the multi-angle argon arc welding equipment, and a vertical beam pretreatment module for pretreatment of the end surface of the door vertical pipe is fixedly connected to the free end of the second hydraulic rod; The vertical beam preprocessing module includes an installation frame, a first hydraulic rod, and a lifting frame. The side of the installation frame is fixedly connected to a second hydraulic rod. The bottom of the installation frame is fixedly connected to a first hydraulic rod, and the free end of the first hydraulic rod is fixedly connected to a lifting frame. Inside the installation frame, there is a vertically distributed limiting mechanism fixedly connected. Inside the limiting mechanism, there is a vertically arranged vertical beam side processing mechanism for grinding the side of the door vertical pipe. Above and below the lifting frame, there is a vertical beam upper and lower surface processing mechanism for grinding the upper and lower ends of the door vertical pipe. One side of the lifting frame is provided with a guide groove; The vertical beam side processing mechanism includes a lifting device, a C-shaped frame, and a first motor. The outside of the lifting device is fixedly connected to the lifting frame. The outside of the lifting device is slidably connected to a C-shaped frame. Inside the C-shaped frame, there is a first motor, and the end of the main shaft of the first motor is fixedly connected to a rotating rod. The outside of the rotating rod is fixedly connected with a gradient grinding piece.

[0005] Currently, there is also a special production line for sealing the door vertical pipe. However, during the sealing work, it generally does not have a special mechanism for processing both ends of the door vertical pipe. It uses a method of directly butting and welding a sealing plate to the door vertical pipe for sealing. Although it can also perform the sealing work, once the burrs, protrusions, or impurities at both ends of the door vertical pipe are relatively large, there will be a situation of incomplete sealing, resulting in quality problems such as missed welding and false welding, seriously affecting the product quality. When in use, before the door vertical pipe is welded, the first hydraulic rod drives the lifting frame to move, and the second hydraulic rod is started to drive the lifting frame to be located at both ends of the door vertical pipe, and the door vertical pipe is inserted into it. The door vertical pipe is fixed at both ends by the limiting mechanism. The vertical beam side processing mechanism is started to make the rotating rod move at both ends of the door vertical pipe, and the gradient guide roller is located outside both ends of the door vertical pipe. By starting the first motor to drive the rotating rod to rotate, at this time, the gradient guide roller rotates to grind the end face of the door vertical pipe. At the same time, the outer side of the large-diameter cylinder of the gradient guide roller can contact and grind the two side faces of the door vertical pipe, realizing full grinding of both ends of the door vertical pipe and avoiding the burrs on the side of the door vertical pipe protruding after grinding, which affects the sealing quality of the door vertical pipe.

[0006] As an optional scheme of the automatic welding of the container sealing plate of the present invention, wherein: a blanking groove is provided at the bottom of the lifting frame, and an inclined groove is provided on the side of the installation frame.

[0007] The impurities dropped during grinding can fall through the blanking groove and the inclined groove, ensuring the continuous use of the equipment.

[0008] As an optional scheme of the automatic welding of the container sealing plate of the present invention, wherein: the gradient grinding piece is made of two cylinders with different outer diameters, and the surface facing the small-diameter cylinder of the large-diameter cylinder is the grinding surface, and the outer surface of the small-diameter cylinder is the grinding surface.

[0009] As an alternative solution for the automatic welding of the container sealing plate of the present invention, the following is provided: A fixing plate is fixedly connected to the outside of the first motor. A guiding column is slidably connected inside the fixing plate, and both ends of the guiding column are fixedly connected to a C-shaped frame. A second spring is also fixedly connected to the outside of the fixing plate, and the other end of the second spring is fixedly connected to the C-shaped frame.

[0010] As an alternative solution for the automatic welding of the container sealing plate of the present invention, the following is provided: Sliding grooves are formed on both sides of the lifting device, and the C-shaped frame is slidably connected to the lifting device through the sliding grooves.

[0011] The provided gradient grinding member can not only grind the end face of the door vertical pipe, but also grind the side part of the end of the door vertical pipe, ensuring that during subsequent installation, burrs and other impurities are prevented from coming into contact with the skin of the staff and causing scratches. When the gradient guide roller contacts the end face of the door vertical pipe, it squeezes the fixing plate through the second spring, and the fixing plate drives the first motor to move. At this time, the gradient guide roller can adaptively contact the door vertical pipe to ensure sufficient grinding of both ends of the door vertical pipe.

[0012] As an alternative solution for the automatic welding of the container sealing plate of the present invention, the following is provided: The limiting mechanism includes a fixing frame, a fixing cylinder, and a first spring. The outside of the fixing frame is fixedly connected to a lifting frame. A fixing cylinder is fixedly connected inside the fixing frame. A sliding rod is slidably connected inside the fixing cylinder. The other end of the sliding rod is fixedly connected to a top block, and a limiting column is fixedly connected inside the top block. Both ends of the limiting column are slidably connected to the inner wall of the lifting frame. A first spring is also provided outside the fixing cylinder, and one end of the first spring is fixedly connected to the fixing frame, and the other end of the first spring is fixedly connected to the top block.

[0013] As an alternative solution for the automatic welding of the container sealing plate of the present invention, the following is provided: The upper and lower sides of the top block are provided with inclined surfaces, and multiple groups of rotating rollers are arranged inside the inclined surfaces. Shafts are fixedly connected inside the rotating rollers, and both ends of the shafts are rotatably connected to the top block.

[0015] When grinding the two ends of the door vertical pipe, the limiting mechanism contacts it in advance. At this time, the door vertical pipe is pre-fixed, and then the grinding process is carried out by the side processing mechanism of the vertical beam. When the side processing mechanism of the vertical beam contacts the limiting mechanism, the limiting mechanism is squeezed and moved. At this time, it can ensure that the side processing mechanism of the vertical beam smoothly crosses the limiting mechanism to achieve full grinding of the end face of the door vertical pipe. After the grinding work is completed, the lifting frame moves away from the door vertical pipe. At this time, the limiting mechanism still contacts the door vertical pipe to prevent the lifting frame from driving the door vertical pipe to move and cause misalignment, which affects the subsequent processing quality.

[0016] As an alternative embodiment of the automatic welding of the container sealing plate of the present invention, wherein: the upper and lower surface processing mechanism of the vertical beam includes a protective frame, a second motor and a grinding roller.

[0019] Compared with the prior art, the beneficial effects of the present invention are: When the present invention is in use, before the door vertical pipe is welded, the first hydraulic rod drives the lifting frame to move. The second hydraulic rod is started to drive the lifting frame to be located at both ends of the door vertical pipe, and the door vertical pipe is inserted therein. The limiting mechanism fixes both ends of the door vertical pipe. The side processing mechanism of the vertical beam is started to make the rotating rod move at both ends of the door vertical pipe, and the gradient grinding part is located outside both ends of the door vertical pipe. By starting the first motor to drive the rotating rod to rotate, the gradient grinding part rotates to grind the end face of the door vertical pipe. At the same time, the outer side of the large-diameter cylinder of the gradient grinding part can contact and grind the two side faces of the door vertical pipe to achieve full grinding of both ends of the door vertical pipe, and prevent the burrs on the side of the door vertical pipe from protruding and affecting the sealing quality of the door vertical pipe after grinding; When the gradient grinding part contacts the end face of the door vertical pipe, it squeezes the fixed plate through the second spring, and the fixed plate drives the first motor to move. At this time, the gradient grinding part can adaptively contact the door vertical pipe to ensure full grinding treatment of both ends of the door vertical pipe; When grinding the two ends of the door vertical pipe, the limiting mechanism contacts it in advance, fixing the door vertical pipe in advance. Then, the grinding process is carried out by the side processing mechanism of the vertical beam. When the side processing mechanism of the vertical beam contacts the limiting mechanism, the limiting mechanism is squeezed and moved. At this time, it can ensure that the side processing mechanism of the vertical beam smoothly crosses the limiting mechanism to achieve the full grinding of the end face of the door vertical pipe. After the grinding work is completed, the lifting frame moves away from the door vertical pipe. At this time, the limiting mechanism still contacts the door vertical pipe to prevent the lifting frame from driving the door vertical pipe to move and cause misalignment, which affects the subsequent processing quality; The second motor drives the grinding roller to rotate, and the grinding roller can grind the upper and lower sides of the end face of the door vertical pipe to ensure that the outer part of the end face of the door vertical pipe is fully ground, guarantee the subsequent welding quality, and prevent burrs and other impurities from scratching the staff; The impurities falling off during grinding can fall through the blanking groove and the inclined groove to ensure the continuous use of the equipment.

Detailed implementation mode

[0022] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 11 , the present invention provides a technical solution: Automatic welding of container sealing plates, including a blanking machine 1, a material disassembling machine 2 and an equidistant conveyor 3; On one side of the above-mentioned blanking machine 1, there is installed a material disassembling machine 2 for driving the movement of the door vertical pipe, and on one side of the material disassembling machine 2, there is provided an equidistant conveyor 3 for equidistant placement of the door vertical pipe. On one side of the above-mentioned equidistant conveyor 3, there is provided a reciprocating feeding machine 4 for driving the feeding of the door vertical pipe. On one side of the above-mentioned reciprocating feeding machine 4, there is provided a positioning device 6 for limiting the door vertical pipe. On one side of the above-mentioned positioning device 6, there is provided a blanking machine 8 for the door vertical pipe to be discharged. On both sides of the above-mentioned positioning device 6, there is provided a multi-angle argon arc welding equipment 5 for sealing both sides of the door vertical pipe. On the outside of the above-mentioned multi-angle argon arc welding equipment 5, there is provided a welding machine jig 7 for the argon arc welding equipment; On one side of the above-mentioned multi-angle argon arc welding equipment 5, there is also fixedly connected a second hydraulic rod 10, and the free end of the second hydraulic rod 10 is fixedly connected with a vertical beam pretreatment module 9 for preprocessing the end face of the door vertical pipe; The vertical beam preprocessing module 9 includes a mounting frame 901, a first hydraulic rod 902 and a lifting frame 903. The side of the mounting frame 901 is fixedly connected to the second hydraulic rod 10. The bottom of the mounting frame 901 is fixedly connected to the first hydraulic rod 902. The free end of the first hydraulic rod 902 is fixedly connected to the lifting frame 903. The interior of the mounting frame 901 is fixedly connected to a limiting mechanism 904 distributed up and down. The inner wall of the limiting mechanism 904 is vertically installed with a vertical beam side processing mechanism 905 for grinding the side of the door vertical pipe. The upper and lower sides of the lifting frame 903 are installed with a vertical beam upper and lower surface processing mechanism 906 for grinding the upper and lower ends of the door vertical pipe. A guide groove 907 is provided on one side of the lifting frame 903. The vertical beam side processing mechanism 905 includes a lifting device 9051, a C-shaped frame 9052 and a first motor 9053. The outer side of the lifting device 9051 is fixedly connected to the lifting frame 903. The outer side of the lifting device 9051 is slidably connected to the C-shaped frame 9052. The first motor 9053 is installed inside the C-shaped frame 9052. The main shaft end of the first motor 9053 is fixedly connected to a rotating rod 9057. The outer side of the rotating rod 9057 is fixedly connected to a gradient grinding piece 9058.

[0023] At present, there are also special production lines for sealing door vertical pipes. However, when sealing, there is generally no mechanism for processing the two ends of the door vertical pipe. The sealing plate is directly butt-welded to the door vertical pipe. Although it can also perform the sealing work, once the burrs, protrusions or impurities at the two ends of the door vertical pipe are large, the sealing is not tight, and the quality problems of welding leakage and cold welding occur, which seriously affect the product quality. When in use, before welding, the door vertical pipe drives the lifting frame 903 to move through the first hydraulic rod 902, and drives the lifting frame 903 to be located at the two ends of the door vertical pipe through the second hydraulic rod 10, and makes The door vertical tube is inserted therein, and the two ends of the door vertical tube are fixed by the limiting mechanism 904. The side processing mechanism 905 of the vertical beam is started to make the rotating rod 9057 move at the two ends of the door vertical tube, and the gradient guide roller 9058 is located at the outer side of the two ends of the door vertical tube. By starting the first motor 9053 to drive the rotating rod 9057 to rotate, the gradient guide roller 9058 rotates to grind the end surface of the door vertical tube. At the same time, the outer side of the large-diameter cylinder of the gradient guide roller 9058 can contact and grind with the two side surfaces of the door vertical tube to achieve full grinding of the two ends of the door vertical tube, so as to avoid the burrs on the side of the door vertical tube protruding after the grinding is completed, thereby affecting the sealing quality of the door vertical tube; In this embodiment, argon arc welding is adopted for the automatic welding. After welding is completed, slag cleaning and grinding of the welded part are not required, which not only eliminates manual grinding, but also adopts TIG (non-consumable electrode argon arc welding). The electrode of this argon arc welding is a tungsten electrode, which does not melt during the welding process. The filling material of the weld bead is filled by the molten metal liquid of the base material and the local sealing plate. The welding wire is directly omitted. There is a special door vertical pipe sealing plate station on the assembly line, which is generally responsible for welding, slag cleaning, grinding and other work by 4-6 people. Calculated according to 500 standard boxes per single shift, this station needs to weld 500×4×2 = 4,000 thousand sealing plates per shift. This equipment is fully automatic production, and this assembly line can be operated by 1 employee. The designed production capacity is 270 pieces / hour, equivalent to 65 standard boxes / hour. Compared with the same production capacity of pure manual welding, 6 excellent welders are required. Therefore, 5 welders' direct costs can be saved in the comparison of the same production capacity. Compared with traditional manual welding, the product quality of this equipment is stable. For the fully automatic equipment, the equipment will not be fatigued or sleepy during normal operation, nor will it affect production due to the temporary replacement of operators. This equipment adopts fully automatic production, and "man-machine separation" is completely realized during the normal production process, basically meeting the requirements of intrinsic safety, fundamentally solving the labor intensity of employees and the safety hazards caused by fatigue, misoperation, etc.; The blanking machine 1 is in a pure manual mode, and employees need to manually place the door vertical pipe on the inclined slideway. The automatic blanking machine 2 is coordinated by the lifting cylinder and the horizontal cylinder to place the door vertical pipes on the inclined track on the automatic equidistant conveyor 3 one by one. This process is fully automatic. The automatic equidistant conveyor 3 is used to arrange the door vertical pipes sent by the automatic blanking machine 2 at equal intervals to prepare for the reciprocating feeding machine 4. This process is fully automatic. The standard spacing is 762 (the pitch of the 12A-1 chain is 19.05, and the spacing is 40 pitches, that is, 19.05×40 = 762). The function of the reciprocating feeding machine 4 is to realize the cyclic alternation of the three materials of "waiting for welding", "being welded" and "welding completed". This process is fully automatic. The function of the automatic clamping and positioning device 6 is to position and clamp the door vertical pipe in the height and horizontal directions. This process is fully automatic. The multi-angle argon arc welding equipment 5 is divided into four groups of X-direction moving mechanisms and four groups of Y-direction moving mechanisms for welding the end faces of the door vertical pipes. The automatic blanking machine 8 is used to send the welded door vertical pipes sent out by the automatic reciprocating feeding machine 4 to the blanking area.

[0024] Embodiment 2: This embodiment is an improvement made to Embodiment 1. Please refer to Figure 8 and Figure 9 , specifically, a blanking groove is opened at the bottom of the lifting frame 903, and an inclined groove is opened on the side surface of the installation frame 901.

[0025] The impurities falling off during grinding can fall through the blanking groove and then through the inclined groove of the installation frame 901, preventing the impurities from falling inside the installation frame 901 and ensuring the continuous use of the equipment.

[0026] Embodiment 3: This embodiment is an improvement on Embodiment 2. Please refer to Figure 11 , specifically, the above-mentioned gradient grinding member 9058 is made of two cylinders with different outer diameters, and the surface of the large-diameter cylinder facing the small-diameter cylinder is the grinding surface, and the outer surface of the small-diameter cylinder is the grinding surface.

[0027] A fixing plate 9054 is fixedly connected to the outside of the first motor 9053. A guide post 9056 is slidably connected inside the fixing plate 9054, and both ends of the guide post 9056 are fixedly connected to the C-shaped frame 9052. A second spring 9055 is also fixedly connected to the outside of the fixing plate 9054, and the other end of the second spring 9055 is fixedly connected to the C-shaped frame 9052.

[0028] Chute grooves are provided on both sides of the lifting device 9051, and the C-shaped frame 9052 is slidably connected to the lifting device 9051 through the chute grooves.

[0029] The provided gradient grinding member 9058 can not only grind the end face of the door vertical pipe, but also grind the side part of the end of the door vertical pipe, ensuring that during subsequent installation, burrs and other impurities are prevented from coming into contact with the skin of the staff and causing scratches. When the gradient guide roller 9058 contacts the end face of the door vertical pipe, it squeezes the fixing plate 9054 through the second spring 9055, and the fixing plate 9054 drives the first motor 9053 to move. At this time, the gradient guide roller 9058 can adaptively contact the door vertical pipe to ensure sufficient grinding of both ends of the door vertical pipe; In this embodiment, the outer side of the small-diameter cylinder of the grinding roller 9058 contacts the end face of the door vertical pipe, and the rotation thereof realizes the grinding of the end face of the door vertical pipe. The large-diameter side of the guide roller 9058 contacts the side of the door vertical pipe, and at this time, it is used to grind the side of the door vertical pipe to prevent burrs from protruding and affecting subsequent work. The provided second spring 9055 can enable the rotating rod 9057 of the first motor 9053 to perform adaptive adjustment when it contacts the door vertical pipe, ensuring the grinding quality and avoiding excessive contact and collision with the door vertical pipe, thus ensuring the grinding quality.

[0030] Embodiment 4: This embodiment is an improvement on Embodiment 3. Please refer to Figure 10, Specifically, the above-mentioned limiting mechanism 904 includes a fixed frame 9041, a fixed cylinder 9042 and a first spring 9043. The outer side of the fixed frame 9041 is fixedly connected to the lifting frame 903. The fixed cylinder 9042 is fixedly connected inside the fixed frame 9041. A sliding rod 9044 is slidably connected inside the fixed cylinder 9042. The other end of the sliding rod 9044 is fixedly connected to a top block 9045, and a limiting column 9046 is fixedly connected inside the top block 9045. Both ends of the limiting column 9046 are slidably connected to the inner wall of the lifting frame 903. A first spring 9043 is also arranged outside the fixed cylinder 9042. One end of the first spring 9043 is fixedly connected to the fixed frame 9041, and the other end of the first spring 9043 is fixedly connected to the top block 9045.

[0031] Both the upper and lower sides of the above-mentioned top block 9045 are arranged as inclined surfaces, and multiple rotating rollers 9048 are arranged inside the inclined surfaces. The rotating shafts 9047 are fixedly connected inside the rotating rollers 9048. Both ends of the rotating shafts 9047 are rotatably connected to the top block 9045.

[0032] Chute grooves are opened on both sides of the fixed frame 9041, and a limiting block 9049 is slidably connected to the fixed frame 9041 through the chute grooves. The other end of the limiting block 9049 is fixedly connected to the top block 9045.

[0033] When grinding the two ends of the door vertical pipe, the limiting mechanism 904 contacts it in advance, and at this time, the door vertical pipe is fixed in advance. Then, the grinding process is carried out by the side processing mechanism 905 of the vertical beam. When the side processing mechanism 905 of the vertical beam contacts the limiting mechanism 904, the limiting mechanism 904 is squeezed and moves. At this time, it can ensure that the side processing mechanism 905 of the vertical beam smoothly crosses the limiting mechanism 904 to achieve the full grinding of the end face of the door vertical pipe. After the grinding work is completed, the lifting frame 903 moves to separate from the door vertical pipe. At this time, the limiting mechanism 904 still contacts the door vertical pipe to prevent the lifting frame 903 from driving the door vertical pipe to move and cause misalignment, affecting the subsequent processing quality. In this embodiment, the inclined surfaces on both sides of the set top block 9045 are used for the side processing mechanism 905 of the vertical beam to contact it, which serves a guiding purpose. At the same time, the set rotating shafts 9047 and 9048 can ensure that the sliding friction is transformed into rolling friction, facilitating the smooth movement of the side processing mechanism 905 of the vertical beam, and the limiting block 9049 can prevent the fixed frame 9041 from separating from the top block 9045, serving a limiting purpose.

[0034] Embodiment 5: This embodiment is an improvement made to Embodiment 4. Please refer to Figure 13, Specifically, the upper and lower surface processing mechanism 906 of the above vertical beam includes a protective frame 9061, a second motor 9062, and a grinding roller 9063. The outer side of the protective frame 9061 is fixedly connected to the lifting frame 903. A second motor 9062 is arranged inside the protective frame 9061, and the end of the main shaft of the second motor 9062 is fixedly connected to a grinding roller 9063.

[0035] The outer side of the second motor 9062 is fixedly connected to an up and down moving plate 9064. The other end of the up and down moving plate 9064 is fixedly connected to a plurality of third springs 9065, and the other end of the third spring 9065 is fixedly connected to the protective frame 9061.

[0036] The arranged second motor 9062 drives the grinding roller 9063 to rotate, and the grinding roller 9063 can grind the upper and lower sides of the end surface of the door vertical pipe, ensuring that the outer part of the end surface of the door vertical pipe is fully ground, guaranteeing the subsequent welding quality, and avoiding burrs and other impurities from scratching the staff. In this embodiment, through the cooperation of the side surface processing mechanism 905 of the vertical beam and the upper and lower surface processing mechanism 906 of the vertical beam, the end surface and the outer part of the end surface of the door vertical pipe can be ground, guaranteeing the welding quality of the subsequent sealing plate. The arrangement of the third spring 9065 and the up and down moving plate 9064 can make the grinding roller 9063 move adaptively, avoiding damage caused by over-grinding or violent contact.
