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:

[0005] 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;

[0006] 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;

[0007] 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;

[0008] The vertical beam preprocessing module comprises a mounting frame, a first hydraulic rod and a lifting frame, the side of the mounting frame is fixedly connected to the second hydraulic rod, the bottom of the mounting frame is fixedly connected to the first hydraulic rod, the free end of the first hydraulic rod is fixedly connected to the lifting frame, the interior of the mounting frame is fixedly connected to a limiting mechanism distributed up and down, the inner wall of the limiting mechanism is vertically installed with a vertical beam side processing mechanism for grinding the side of the door vertical pipe, the upper and lower sides of the lifting frame are installed with a vertical beam upper and lower surface processing mechanism for grinding the upper and lower ends of the door vertical pipe, and a guide groove is opened on one side of the lifting frame;

[0009] The vertical beam side processing mechanism includes a lifting device, a C-shaped frame and a first motor. The outer side of the lifting device is fixedly connected to the lifting frame. The outer side of the lifting device is slidably connected to the C-shaped frame. The first motor is installed inside the C-shaped frame. The end of the main shaft of the first motor is fixedly connected to a rotating rod, and the outer side of the rotating rod is fixedly connected to a gradient grinding part.

[0010] At present, there are also special production lines for sealing door risers. However, when sealing, there is generally no mechanism for processing the two ends of the door riser. The sealing plate is directly butt-welded to the door riser. Although it can also perform the sealing work, once the burrs, protrusions or impurities at both ends of the door riser 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 riser drives the lifting frame to move by the first hydraulic rod, and the lifting frame is driven to move by the second hydraulic rod. The two ends of the door vertical tube are fixed by the limiting mechanism, and the side processing mechanism of the vertical beam is started to make the rotating rod move at the two ends of the door vertical tube, and the gradient guide roller is located at the outer side of the two ends of the door vertical tube, and the rotating rod is driven to rotate by starting the first motor. At this time, the gradient guide roller rotates to grind the end face of the door vertical tube. At the same time, the outer side of the large-diameter cylinder of the gradient guide roller can contact and grind with the side surfaces of both sides of the door vertical tube to achieve sufficient 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.

[0011] As an optional solution for the automatic welding of container cover plates of the present invention, a material discharge chute is provided at the bottom of the lifting frame, and an inclined groove is provided at the side of the installation frame.

[0012] Impurities dropped during grinding can fall through the discharge chute and the tilting chute, ensuring the continuous use of the equipment.

[0013] As an optional solution for the automatic welding of container cover plates described in the present invention, the gradient polishing parts are made of two groups of cylinders with different outer diameters, and the side of the large-diameter cylinder facing the small-diameter cylinder is the polishing surface, and the outer surface of the small-diameter cylinder is the polishing surface.

[0014] As an alternative solution for the automatic welding of the container sealing plate described in the present invention, wherein: 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.

[0015] As an alternative solution for the automatic welding of the container sealing plate described in the present invention, wherein: 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.

[0016] 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 contacting 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.

[0017] As an alternative solution for the automatic welding of the container sealing plate described in the present invention, wherein: the limiting mechanism includes a fixing frame, a fixing cylinder and a first spring, the outside of the fixing frame is fixedly connected to the 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 arranged on the outside of 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.

[0018] As an alternative solution for the automatic welding of the container sealing plate described in the present invention, wherein: the upper and lower sides of the top block are arranged as inclined planes, and multiple groups of rotating rollers are arranged inside the inclined planes, and rotating shafts are fixedly connected inside the rotating rollers, and both ends of the rotating shafts are rotatably connected to the top block.

[0019] As an alternative solution for the automatic welding of the container sealing plate described in the present invention, wherein: sliding grooves are formed on both sides of the fixing frame, and a limiting block is slidably connected to the fixing frame through the sliding grooves, and the other end of the limiting block is fixedly connected to the top block.

[0020] When polishing the two ends of the door vertical pipe, its limiting mechanism contacts it in advance, and at this time, the door vertical pipe is pre-fixed. Then, the polishing 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 polishing of the end face of the door vertical pipe. After the polishing work is completed, the lifting frame moves and separates 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.

[0021] 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 polishing roller. The outer side of the protective frame is fixedly connected to the lifting frame. A second motor is arranged inside the protective frame, and a polishing roller is fixedly connected to the end of the main shaft of the second motor.

[0022] As an alternative embodiment of the automatic welding of the container sealing plate of the present invention, wherein: the outer side of the second motor is fixedly connected with an up-and-down moving plate, and the other end of the up-and-down moving plate is fixedly connected with a plurality of third springs, and the other end of the third spring is fixedly connected with the protective frame.

[0023] The second motor drives the polishing roller to rotate, and the polishing roller can polish 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 polished, guarantee the subsequent welding quality, and prevent burrs and other impurities from scratching the staff.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] When the present invention is in use, before the door vertical pipe is welded, the lifting frame is driven to move by the first hydraulic rod. The lifting frame is driven by the second hydraulic rod to be located at both ends of the door vertical pipe, and the door vertical pipe is inserted into it. The two ends of the door vertical pipe are fixed by the limiting mechanism. 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 member 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 member rotates to polish the end face of the door vertical pipe. At the same time, the outer side of the large-diameter cylinder of the gradient grinding member can contact and polish the two side faces of the door vertical pipe to achieve the full polishing 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 polishing;

[0026] When the gradient grinding member 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 member can adaptively contact the door vertical pipe to ensure the full polishing treatment of both ends of the door vertical pipe;

[0027] When grinding the two ends of the door vertical pipe, its limiting mechanism contacts it in advance, thus realizing the pre-fixation of the door vertical pipe. Then, the grinding process is carried out through 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 extruded 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.

[0028] The second motor is set to drive 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.

[0029] The impurities falling off during grinding can fall through the blanking groove and the inclined groove to ensure the continuous use of the equipment. Description of the Drawings

DETAILED DESCRIPTION

[0044] 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:

[0045] Automatic welding of container cover plates, including a material swinging machine 1, a material unloading machine 2 and an equidistant conveyor 3;

[0046] On one side of the above-mentioned blanking machine 1, a disassembling machine 2 for driving the vertical door pipe to move is installed, and on one side of the disassembling machine 2, an equidistant conveyor 3 for arranging the vertical door pipes at equal intervals is provided. On one side of the above-mentioned equidistant conveyor 3, a reciprocating feeding machine 4 for driving the vertical door pipes to be fed is provided. On one side of the above-mentioned reciprocating feeding machine 4, a positioning device 6 for limiting the vertical door pipes is provided. On one side of the above-mentioned positioning device 6, a blanking machine 8 for discharging the vertical door pipes is provided. On both sides of the positioning device 6, a multi-angle argon arc welding device 5 for sealing both sides of the vertical door pipes is provided. Outside the above-mentioned multi-angle argon arc welding device 5, a welding machine jig 7 for placing the argon arc welding device is provided;

[0047] On one side of the above-mentioned multi-angle argon arc welding device 5, a second hydraulic rod 10 is also fixedly connected, and at the free end of the second hydraulic rod 10, a vertical beam pretreatment module 9 for pretreating the end face of the vertical door pipe is fixedly connected;

[0048] The above-mentioned vertical beam pretreatment module 9 includes an installation frame 901, a first hydraulic rod 902 and a lifting frame 903. The side of the above-mentioned installation frame 901 is fixedly connected to the second hydraulic rod 10. The bottom of the above-mentioned installation 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. Inside the above-mentioned installation frame 901, a limiting mechanism 904 distributed vertically is fixedly connected. Inside the inner wall of the above-mentioned limiting mechanism 904, a vertical beam side surface treatment mechanism 905 for grinding the side surface of the vertical door pipe is installed vertically. On the upper and lower sides of the above-mentioned lifting frame 903, a vertical beam upper and lower surface treatment mechanism 906 for grinding the upper and lower ends of the vertical door pipe is installed. On one side of the above-mentioned lifting frame 903, a guiding groove 907 is opened;

[0049] The above-mentioned vertical beam side surface treatment mechanism 905 includes a lifting device 9051, a C-shaped frame 9052 and a first motor 9053. The outside of the above-mentioned lifting device 9051 is fixedly connected to the lifting frame 903. The outside of the above-mentioned lifting device 9051 is slidably connected to the C-shaped frame 9052. Inside the above-mentioned C-shaped frame 9052, a first motor 9053 is installed. At the end of the main shaft of the above-mentioned first motor 9053, a rotating rod 9057 is fixedly connected. On the outside of the above-mentioned rotating rod 9057, a gradient grinding part 9058 is fixedly connected.

[0050] Currently, there is also a dedicated production line for sealing the door vertical pipes. However, during the sealing process, it generally does not have a mechanism specifically for processing both ends of the door vertical pipes. Instead, it uses a method of directly butt-welding the sealing plate to the door vertical pipe for sealing. Although it can also perform the sealing work, when the burrs, protrusions, or impurities at both ends of the door vertical pipe are relatively large, there will be a situation where the sealing is not tight, resulting in quality problems such as incomplete welding and false welding, which seriously affects the product quality. Before welding the door vertical pipe, the lifting frame 903 is driven to move by the first hydraulic rod 902. The second hydraulic rod 10 is activated to drive the lifting frame 903 to be located at both ends of the door vertical pipe, and the door vertical pipe is inserted into it. The two ends of the door vertical pipe are fixed by the limiting mechanism 904. The side processing mechanism 905 of the vertical beam is activated to make the rotating rod 9057 move at both ends of the door vertical pipe, and the gradient guide roller 9058 is located outside both ends of the door vertical pipe. By starting the first motor 9053 to drive the rotating rod 9057 to rotate, the gradient guide roller 9058 can rotate to polish 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 9058 can contact and polish the two side faces of the door vertical pipe, achieving full polishing of both ends of the door vertical pipe and avoiding the burrs on the side of the door vertical pipe protruding after polishing, which affects the sealing quality of the door vertical pipe.

[0051] In this embodiment, the automatic welding uses argon arc welding. After welding is completed, the welded part does not require slag cleaning and polishing, which not only eliminates manual polishing. Using TIG (tungsten inert gas 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 melting of the sealing plate, directly eliminating the need for welding wire. There is a dedicated sealing plate station for door vertical pipes on the production line, and generally 4 - 6 people are responsible for welding, slag cleaning, polishing, etc. Calculated according to 500 standard boxes per single shift, this station needs to weld 500×4×2 = 4000 sealing plates per shift. This equipment is fully automatic production, and this production line can be operated by 1 employee. The designed production capacity is 270 pieces per hour, equivalent to 65 standard boxes per hour. Compared with the same production capacity of pure manual welding, 6 excellent welders are required. Therefore, the direct cost of 5 welders can be saved in terms of the same production capacity. Compared with traditional manual welding, the product quality of this equipment is stable. As a 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 during the normal production process, it completely realizes "separation of man and machine", basically meeting the requirements of intrinsic safety, fundamentally solving the labor intensity of employees and potential safety hazards caused by fatigue, misoperation, etc.

[0052] The blanking machine 1 is a manual method. Employees need to manually place the door vertical pipes on the inclined slideway. The automatic blanking machine 2 coordinates the movement of the lifting cylinder and the horizontal cylinder to place the door vertical pipes on the inclined track one by one on the automatic equidistant conveyor 3. 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 interval is 762 (the pitch of the 12A-1 chain is 19.05, and the interval is 40 pitches, that is, 19.05 multiplied by 40 = 762). The function of the reciprocating feeding machine 4 is to realize the cyclic reciprocating alternation of the three materials of "waiting for welding", "welding", and "welding completed". This process is fully automatic. The automatic clamping and positioning device 6 is used to position and clamp the door vertical pipes in the height and horizontal directions. This process is fully automatic. The multi-angle TIG welding equipment 5 is divided into four groups of X-direction moving mechanisms and four groups of Y-direction moving mechanisms, which are used 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.

[0053] 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 of the installation frame 901.

[0054] 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.

[0055] Embodiment 3: This embodiment is an improvement made to Embodiment 2. Please refer to Figure 11 , specifically, the gradient grinding part 9058 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.

[0056] A fixing plate 9054 is fixedly connected to the outside of the first motor 9053. A guiding column 9056 is slidably connected inside the fixing plate 9054, and both ends of the guiding column 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.

[0057] Chute grooves are opened 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.

[0058] 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 do not come into contact with the skin of the staff and cause scratches. When the gradient guide roller 9058 contacts the end face of the door vertical pipe, it squeezes the fixed plate 9054 through the second spring 9055, and the fixed 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;

[0059] 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 of the grinding roller 9058 is used to grind 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 avoid burrs 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.

[0060] Embodiment 4: This embodiment is an improvement made to 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 outside of the above-mentioned fixed frame 9041 is fixedly connected to the lifting frame 903. The inside of the above-mentioned fixed frame 9041 is fixedly connected to the fixed cylinder 9042. A sliding rod 9044 is slidably connected inside the above-mentioned fixed cylinder 9042. The other end of the above-mentioned sliding rod 9044 is fixedly connected to a top block 9045, and a limiting column 9046 is fixedly connected inside the above-mentioned top block 9045. Both ends of the above-mentioned limiting column 9046 are slidably connected to the inner wall of the lifting frame 903. A first spring 9043 is also provided outside the above-mentioned fixed cylinder 9042, and one end of the above-mentioned first spring 9043 is fixedly connected to the fixed frame 9041, and the other end of the above-mentioned first spring 9043 is fixedly connected to the top block 9045.

[0061] The upper and lower sides of the above-mentioned top block 9045 are provided with inclined surfaces, and multiple groups of rotating rollers 9048 are provided inside the inclined surfaces. The inside of each of the above-mentioned rotating rollers 9048 is fixedly connected to a rotating shaft 9047, and both ends of the above-mentioned rotating shaft 9047 are rotatably connected to the top block 9045.

[0062] Chute grooves are opened on both sides of the above-mentioned fixed frame 9041, and a limiting block 9049 is slidably connected to the fixed frame 9041 through the chute grooves, and the other end of the above-mentioned limiting block 9049 is fixedly connected to the top block 9045.

[0063] 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 extruded and moved. At this time, it can be ensured 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 away 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, which affects the subsequent processing quality;

[0064] In this embodiment, the inclined surfaces on both sides of the top block 9045 are provided for the side processing mechanism 905 of the vertical beam to contact it, which serves as a guiding purpose. At the same time, the rotation shafts 9047 and 9048 provided can ensure that the sliding friction is converted 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 detaching from the top block 9045, serving as a limiting purpose.

[0065] Example 5: This example is an improvement on Example 4. Please refer to Figure 13 , specifically, the upper and lower surface processing mechanism 906 of the vertical beam includes a protective frame 9061, a second motor 9062, and a grinding roller 9063.
