Description

Technical Field

[0001] The present invention relates to a packaging device and a packaging method for automatically packaging a butt welding wire coil. Background Art

[0002] After the welding wire is wound and collected by the wire coil, before leaving the factory, a paper packaging tape needs to be wrapped around the outer circumference of the welding wire coil between the two discs of the wire coil for simple packaging. Summary of the Invention

[0003] In view of this, the present invention provides an automatic packaging device and a packaging method for a welding wire coil, specifically as follows:

[0004] The automatic packaging device for a welding wire coil includes a conveying mechanism, and also includes a winding and packing mechanism. The winding and packing mechanism includes a first platform and two winding units; the upper end of the first platform is connected to a lifting unit that drives its lifting, and the upper end of the lifting unit is connected to a lateral moving unit that drives it and the first platform to move in a horizontal lateral direction perpendicular to the traveling direction of the conveying mechanism; the lower end of the first platform is symmetrically connected to two winding units with the lateral center line perpendicular to the traveling direction of the conveying mechanism as the center;

[0005] Each winding unit includes a rotary cylinder, a first connecting rod, a second connecting rod, a third connecting rod, a first cylinder, a first claw, and a pressing plate. One end of the first connecting rod and one end of the second connecting rod are fixedly connected to the rotating part of the rotary cylinder, and the fixed part of the rotary cylinder is fixed to the first platform;

[0006] The other end of the first connecting rod is fixedly connected to the first claw, and the opening and closing direction of the first claw is perpendicular to the length direction of the first connecting rod;

[0007] The middle part of the first connecting rod is rotatably connected to one end of the third connecting rod below, and the other end of the third connecting rod is fixedly connected to one end of the pressing plate below. The other end of the pressing plate is provided with a U-shaped opening;

[0008] The other end of the second connecting rod is rotatably connected to the bottom of the cylinder body of the first cylinder, and the top of the cylinder rod of the first cylinder is rotatably connected to the middle part of the third connecting rod; and the movement path of the pressing plate driven by the third connecting rod is located between the first claw and the rotation axis of the third connecting rod.

[0009] The conveying mechanism uses a conveying roller that can rotate by itself; it also includes a positioning unit. The positioning unit includes left and right stop columns and a positioning column. There is a gap between the first and second conveying rollers at the packaging station, and the left and right stop columns that move synchronously up and down pass through this gap; there is also a gap between the second and third conveying rollers, and the positioning column that can move up and down passes through this gap; the column axes of the left and right stop columns and the positioning column are parallel to each other, and the vertical distances between the left and right stop columns and the positioning column are the same respectively.

[0010] It further includes a pressing unit which is located on one side of the conveying mechanism in the traveling direction. The pressing unit includes a second cylinder, a third cylinder and a pressing plate. The telescopic direction of the second cylinder is the vertical direction. The cylinder block of the third cylinder is fixed to the cylinder rod of the second cylinder. The telescopic direction of the third cylinder is the horizontal direction. The pressing plate is fixed to the cylinder rod of the third cylinder.

[0011] It further includes a pulling and cutting mechanism which includes a bidirectional lead screw driven by a motor and placed in the track groove. Two nuts of the bidirectional lead screw are respectively fixedly connected with a claw platform and a paper roll platform which are slidably connected with the track groove wall. A pulling claw is fixedly connected to the claw platform through a connecting block. A rotating roller for placing a paper bag reel, several tensioning rollers for tensioning and straightening, a clamping roller and a cutting knife are connected to the paper roll platform. The cutting knife is located between the clamping roller and the pulling claw. After the cutting knife is opened, the pulling claw can clamp the free end of the packaging tape clamped by the clamping roller through the middle gap.

[0012] The automatic packaging method for a welding wire reel uses the above-mentioned automatic packaging device for a welding wire reel.

[0013] It includes the following steps:

[0014] When the welding wire reel is conveyed to the packaging station to be packaged, it is stopped by the left and right stop columns in the raised state. The positioning column rises and extends into the central hole of the spindle of the welding wire reel to lock the position of the welding wire reel. The left and right stop columns descend and retract until the top ends are below the uppermost end of the conveying roller surface.

[0015] The first platform moves horizontally above the welding wire reel until the middle part of the packaging tape clamped by the first claws of the two winding units abuts against one side of the outer peripheral surface of the welding wire coil.

[0016] The second cylinder of the pressing unit drives the third cylinder to rise. The third cylinder drives the pressing plate to closely abut the middle part of the packaging tape against the outer peripheral surface of the welding wire coil.

[0017] The rotary cylinders of the two winding units drive the respective first and second connecting rods to rotate towards the welding wire reel simultaneously. The two first claws respectively clamp the two ends of the packaging tape and wind them to the other side of the welding wire coil, so that the packaging tape surrounds most of the outer peripheral surface of the welding wire coil.

[0018] The cylinder rod of the first cylinder extends, driving the pressing plate on the third connecting rod to press the packaging tape. The first claws release the packaging tape. The pressing plate continues to rotate until the two pressing plates intersect. The packaging tape completely covers the outer peripheral surface of the welding wire coil. The window formed by the C-shaped openings of the two pressing plates is located on the overlapping area of the two ends of the packaging tape. The labeling mechanism pastes the self-adhesive label on the overlapping area and connects and fixes the two ends of the packaging tape together through the self-adhesive label, thus completing the winding and packing.

[0019] After the winding and packaging process is completed, the third cylinder of the pressing unit drives the pressing plate to disengage from the welding wire reel and retract to reset, and the second cylinder drives the third cylinder to descend and reset; the rotary cylinders of the two winding units rotate in the opposite direction until the first claws of the two first connecting rods are located away from each other until the gaps between the claws are located in the same plane; the first cylinder retracts to drive the pressing plate to reset;

[0020] The first platform rises; the positioning column descends and retracts to separate from the axis hole of the reel shaft, and the packaged welding wire reel continues to move forward to the next link driven by the conveying roller;

[0021] The first platform moves to the top of the pulling and cutting mechanism, and the claw platform and the paper roll platform of the pulling and cutting mechanism are driven by the bidirectional screw to approach each other until the pulling claw clamps one end of the packaging belt, and then the bidirectional screw rotates to drive the claw platform and the paper roll platform to move away to the required length, and then the shear cuts the packaging belt, and at the same time the first platform descends, the first claws of the two winding units close to clamp the two ends of the packaging belt, and the pulling claw releases the packaging belt;

[0022] Then repeat the above steps to pack the next welding wire reel.

[0023] The present invention can replace manual packaging, greatly improves the packaging efficiency of welding wire reels, and has a simple structure and convenient maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0035] In addition, for the sake of simplicity of description, the various sensors required for the device to detect that the welding wire spool, each component, etc. reach the corresponding positions are not shown in the figure and are not described in detail in the specification either. However, for those skilled in the art, these are all conventional technical means.

[0036] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.

[0037] As shown in the figure, the automatic packaging device for welding wire spools of the present invention includes a conveying mechanism 3, a winding and packing mechanism, and a pulling and cutting mechanism 10;

[0038] Combined with Figures 1 to 4 As shown, the conveying mechanism 3 adopts a conveying roller type with self-rotating conveying rollers. The welding wire spool 1 advances forward on the sequentially arranged conveying rollers. When it reaches the packaging station to be processed, it is stopped and positioned by the positioning unit so that the winding unit 6 can work;

[0039] The winding and packing mechanism includes a positioning unit, a pressing unit 7, a first platform 5, and two winding units 6;

[0040] Referring to Figure 4As shown, the positioning unit includes left and right stop posts 35, 34 and a positioning post 36. A gap is left between the first and second conveying rollers 31, 32 of the packaging station for passing through the left and right stop posts 35, 34. The left and right stop posts 35, 34 are driven by corresponding power units (not shown in the figure) to rise and fall at the same time. A gap is also left between the second and third conveying rollers 32, 33 for passing through the positioning post 36. The positioning post 36 is driven by corresponding power units (not shown in the figure) to rise and fall. The column axes of the left and right stop posts 35, 34 and the positioning post 36 are parallel to each other, and the vertical distances between the left and right stop posts 35, 34 and the positioning post 36 are the same. The welding wire reel 1 is transported to the waiting When in the packaging station, the left and right stop posts 35 and 34 in the raised state stop it, and the axial center hole 100 of the welding wire reel 1 is located directly above the positioning post 36. Next, the positioning post 36 rises under the drive of its power unit and extends into the axial center hole 100 of the welding wire reel 1 to lock the welding wire reel 1 in position. The left and right stop posts 35 and 34 are driven by their power units to drop and retract to the top end and be located below the uppermost end of the conveyor roller surface to avoid interfering with the subsequent winding and packaging process of the welding wire reel 1. After the winding and packaging process is completed, the positioning post 36 is driven by its power unit to drop and retract to be separated from the axial center hole 100 of the reel shaft, and the welding wire reel 1 continues to move forward to the next link under the drive of the conveyor roller.

[0041] See also Figure 2 The pressing unit is located on the right side of the moving direction of the conveying mechanism, corresponding to the positioning unit, and includes a second cylinder 71, a third cylinder 72 and a pressing plate 73. The extension direction of the second cylinder 71 is vertical, the cylinder body of the third cylinder 72 is fixed to the cylinder rod of the second cylinder 71, the extension direction of the third cylinder 72 is horizontal, and the pressing plate 73 is fixed to the cylinder rod of the third cylinder 72; the pressing plate 73 is used to press the middle part of the packaging belt 2 tightly against the outer peripheral surface of the welding wire coil of the welding wire reel 1 for subsequent winding packaging.

[0042] The upper end of the first platform 5 is connected to the lifting unit 4, which can drive the first platform 5 to rise and fall. The upper end of the lifting unit 4 is also connected to a transverse moving unit (not shown in the figure), which can drive the lifting unit 4 and the first platform 5 to move in a horizontal transverse direction perpendicular to the traveling direction of the conveying mechanism 3, so as to clamp the packaging belt 2 cut by the pulling and cutting mechanism 10 and move it to the packaging station;

[0043] The lower end of the first platform 5 is symmetrically connected to two winding units 6 with a transverse center line perpendicular to the travel direction of the conveying mechanism 3 as the center;

[0044] See also Figure 5As shown, each winding unit includes a first connecting rod 61, a second connecting rod 62, a second connecting portion 621, a third connecting rod 63, a first cylinder 64, a first claw 65, and a pressing plate 66. One end of the first connecting rod 61 and one end of the second connecting rod 62 are both fixedly connected to the rotating portion of the rotary cylinder, and the included angle between their length directions is about ninety degrees. The fixed portion of the rotary cylinder is fixed to the first platform 5;

[0045] The other end of the first connecting rod 61 is fixedly connected to the first claw 65, and the opening and closing direction of the first claw 65 is perpendicular to the length direction of the first connecting rod 61;

[0046] The top end of the first connecting portion 611 is fixedly connected to the lower part of the middle of the first connecting rod 61. The bottom end of the first connecting portion 611 is rotatably connected to one end of the third connecting rod 63. The lower part of the other end of the third connecting rod 63 is fixedly connected to one end of the pressing plate 66 through a connecting rod.

The top end of the cylinder rod of the first cylinder 64 is rotatably connected to the middle of the third connecting rod 63 through a third connecting portion; and the movement path of the pressing plate 66 driven by the third connecting rod 63 is located between the first claw 65 and the rotation axis of the third connecting rod 63.

[0048] See Figure 7 and Figure 8 , the pulling and cutting mechanism 9 includes a bidirectional lead screw 94 placed in the track groove 91 and driven to rotate by a motor (not shown in the figure). The two nuts of the bidirectional lead screw 94 are respectively fixedly connected to a claw platform 92 and a paper roll platform 95 that are slidably connected to the track groove. A pulling claw 93 is fixedly connected to the claw platform 92 through a connecting block. The paper roll platform 95 is connected with a roller for placing the paper bag reel 10, several tensioning rollers 7 for tensioning and straightening, and a cutting unit composed of a main clamping roller 962 and a cutting knife 961. The cutting knife 961 is located between the clamping roller 962 and the pulling claw 93, and after the cutting knife 961 is opened, the pulling claw 93 can clamp the free end of the packaging tape clamped by the clamping roller 962 through the middle gap.

[0049] The working principle and packaging method of this device:

[0050] When the welding wire reel 1 is transported to the packaging station to be processed, it is stopped by the left and right stop posts 35, 34 in the raised state. And, the central hole 100 of the reel shaft of the welding wire reel 1 is located directly above the positioning post 36. The positioning post 36 rises under the drive of its power unit and extends into the central hole 100 of the reel shaft of the welding wire reel 1 to lock the position of the welding wire reel 1. The left and right stop posts 35, 34 then descend and retract under the drive of their power units until the top ends are below the uppermost end of the conveying roller surface to avoid interfering with the subsequent winding and packaging process of the welding wire reel 1;

[0051] After the welding wire spool 1 is locked in position by the positioning post 36, the first platform 5 is driven by the lateral movement unit to move above the welding wire spool 1 until the middle part of the packing tape 2 clamped by the first clamping claws 65 of the two winding units 6 abuts against one side of the outer peripheral surface of the welding wire coil;

[0052] The second air cylinder 71 of the pressing unit drives the third air cylinder 73 to rise, and the third air cylinder 73 drives the pressing plate 73 to closely abut the middle part of the packing tape 2 against the outer peripheral surface of the welding wire coil;

[0053] See Figure 6 , the swing cylinders of the two winding units 6 drive their respective first and second connecting rods 61 and 62 to rotate simultaneously towards the welding wire spool 1, and the two first clamping claws 65 respectively clamp the two ends of the packing tape and wind them to the other side of the welding wire coil, so that the packing tape 2 surrounds most of the outer peripheral surface of the welding wire coil;

[0054] The piston rod of the first air cylinder 64 extends, driving the pressing plate 66 on the third connecting rod 63 to press against the packing tape 2. At the same time, the first clamping claw 65 releases the packing tape 2, and the pressing plate 66 continues to rotate until the two pressing plates 66 intersect. The packing tape 2 completely covers the outer peripheral surface of the welding wire coil, and the window formed by the C-shaped openings of the two pressing plates 66 is located on the overlapping area of the two ends of the packing tape 2. The labeling mechanism (not shown in the figure) pastes the self-adhesive label on the overlapping area and connects and fixes the two ends of the packing tape 2 together through the self-adhesive label, thus completing the winding and packing; there are many existing technical structure solutions for the labeling mechanism, so the present invention will not be elaborated herein.

[0055] After the winding and packing process is completed, the third air cylinder 73 of the pressing unit drives the pressing plate 73 to disengage from the welding wire spool and retract to its original position, and the second air cylinder 71 drives the third air cylinder 73 to descend and return to its original position; the swing cylinders of the two winding units 6 rotate in the reverse direction to the state A as shown in Figure 6 , so that the first clamping claws 65 of the two first connecting rods 61 are located far away from each other until the claw gaps are in the same plane, so as to clamp the two ends of the next packing tape; the first air cylinder 64 retracts to drive the pressing plate to return to its original position;

[0056] The first platform 5 is driven by the lifting unit 4 to rise, the positioning post 36 is driven by its power unit to descend and retract out of the spindle hole 100 of the disc shaft, and the welding wire spool 1 continues to move forward to the next link under the drive of the conveying roller;

[0057] The first platform 5 is driven by the lateral moving unit to move above the pulling and cutting mechanism 9, and the claw platform 92 and the paper roll platform 95 of the pulling and cutting mechanism are driven by the bidirectional screw 94 driven by the motor to approach each other until the pulling claw 93 clamps one end of the packaging belt, and then the bidirectional screw 94 rotates in the direction to drive the claw platform 92 and the paper roll platform 95 to move away from each other to the required length, and then the shear knife 961 cuts the packaging belt, and at the same time, the first platform 5 is driven by the lifting unit 4 to descend, and the first claws 65 of the two winding units 6 close to clamp the two ends of the packaging belt, and the pulling claw 93 releases the packaging belt;

[0058] Then repeat the above steps to pack the next welding wire reel.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
