Description

Technical Field

[0002] Automobile tires are one of the important parts of automobiles. They are in direct contact with the road surface and work together with the automobile suspension to mitigate the impact of the car when it is driving. Whether it is a semi-steel tire, a full-steel tire or a special tire, the tire needs to be packaged after production. When packaging, the packaging film is passed through the inner hole of the tire and then wrapped around the tire. The tire is packaged through multiple turns of winding.

[0003] The packaging of tires is mostly completed by a stretch film packaging machine. The main structure of the existing stretch film packaging machine includes a machine table and a C-frame. When the tire is supported on the machine table, one side of the tire will enter the C-frame due to the opening of the C-frame, and then the C-frame rotates around its own axis, and the packaging film is continuously wrapped around the tire through its own rotation.

That is, the packaging film cannot be wrapped around the QR code during packaging. Existing wrapping film packaging machines require manual identification of the QR code position during packaging, and then adjust the tire position according to the QR code position before packaging. This reduces the automation of packaging operations and reduces packaging efficiency. Utility Model Content

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is clearly and completely described below in conjunction with the drawings of the present invention. Based on the embodiments in this application, other similar embodiments obtained by ordinary technicians in this field without making creative work should all fall within the scope of protection of this application. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention.

[0043] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0044] Embodiment: A high positioning accuracy stretch film packaging device, see attached Figure 1 -Attached Fig.10 , including a positioning device 1 and a packaging device 2. The positioning device 1 is used to identify the position of the QR code on the tire and adjust the position of the tire packaging according to the position of the QR code. The positioning device 1 can also read the QR code information; the packaging device 2 is used to receive the tire adjusted by the positioning device 1 and package the tire.

[0045] Specifically, the positioning device 1 includes a first supporting and conveying mechanism 11, a visual recognition mechanism and a first centering and rotating clamping mechanism 12. The first supporting and conveying mechanism 11 is used to support and convey the tire, and the axis of the tire is vertical when it is on the first supporting and conveying mechanism 11; the visual recognition mechanism is used to identify the position of the QR code on the tire; the first centering and rotating clamping mechanism 12 is used to rotate the tire according to the position of the QR code to adjust the position of the tire packaging.

[0046] The position of the QR code on the tire can be identified by a visual recognition mechanism. After the position of the QR code on the tire is identified, the tire is rotated by the first pair of centering rotating clamping mechanisms 12 to rotate the QR code to a predetermined position. The predetermined position is a pre-set position, that is, each tire will rotate the QR code to a predetermined position on the positioning device 1, so that after the tire is transferred to the packaging device 2 through the positioning device 1, the position of the QR code of the tire on the packaging device 2 is fixed, so that the packaging device 2 only needs to move the QR code out of the way when packaging the tire, and there is no need to manually adjust the position of the QR code, thereby improving the automation of packaging and the packaging efficiency.

[0047] Specifically, the first supporting and conveying mechanism 11 includes a supporting frame 31 and a plurality of supporting rollers 32 arranged on the supporting frame 31, and the plurality of supporting rollers 32 are arranged along the feeding and discharging direction of the tire; the supporting and conveying mechanism also includes a lifting frame 33, and the lifting frame 33 is lifted up and down relative to the supporting frame 31, and a plurality of balls 34 are arranged on the top of the lifting frame 33, and the balls 34 can rotate around their own sphere centers on the lifting frame 33; the lifting frame 33 moves upward, and can drive the plurality of balls 34 to pass upward through two adjacent supporting rollers 32 and can make the height of the balls 34 higher than the supporting rollers 32, thereby lifting the tire on the supporting rollers 32 so that the first centering rotating clamping mechanism 12 can drive the tire to rotate around its own axis.

[0048] When the visual recognition mechanism recognizes the QR code on the tire, the lifting frame 33 is located below the tire. After the visual recognition mechanism completes the recognition of the QR code on the tire, the lifting frame 33 moves upward, and the tire is lifted up by the ball bearings 34 on the lifting frame 33, so that the tire can smoothly rotate around its own axis with the support of the ball bearings 34, thereby facilitating the adjustment of the position of the QR code.

[0049] Specifically, the first pair of rotating clamping mechanisms 12 includes a crossbeam 41 arranged above the support frame 31, and both ends of the crossbeam 41 are fixedly connected to the support frame 31 by vertical rods. The length direction of the crossbeam 41 is horizontal and perpendicular to the feeding and discharging direction of the tire; two sliding frames 42 are arranged on the crossbeam 41, and the sliding frames 42 slide on the crossbeam 41 along the length direction of the crossbeam 41. Two positioning rollers 43 are rotatably connected to each sliding frame 42, and the two positioning rollers 43 on the same sliding frame 42 are arranged along the feeding and discharging direction of the tire; the length direction of the support frame 31 is arranged along the feeding and discharging direction of the tire, and in order to enable the positioning rollers 43 on the two sliding frames 42 to position the tire at the same time, the positioning rollers 43 on the two sliding frames 42 are symmetrically arranged relative to the middle position in the width direction of the support frame 31.

[0050] When the tire needs to be positioned, the tire is first clamped in the middle by the positioning rollers 43 on the two sliding frames 42. At this time, the axis of the tire is located in the middle position in the width direction of the support frame 31, and then the tire is driven to rotate by the positioning rollers 43 to adjust the position of the QR code on the tire.

[0051] In order to enable the positioning roller 43 to drive the tire to rotate, in this embodiment, at least one positioning roller 43 of the first pair of rotating clamping mechanisms 12 is configured to be driven to rotate by a motor.

[0052] Specifically, a rotating rod 44 is rotatably connected to the top of the crossbeam 41. The length direction of the rotating rod 44 is horizontal and the middle position of the length direction is rotatably connected to the crossbeam 41. The rotation axis of the rotating rod 44 is vertical. Two connecting rods 45 are hinged at both ends of the rotating rod 44. The other ends of the two connecting rods 45 are respectively hinged to the two sliding frames 42. A motor is provided on the crossbeam 41 that is transmission-connected to the rotating rod 44. The rotating rod 44 is driven to rotate by the motor. When the rotating rod 44 rotates, the two sliding frames 42 can be driven to slide toward or away from each other through the two connecting rods 45. Through the arrangement of the rotating rod 44 and the connecting rod 45, the two sliding frames 42 can be driven to slide toward or away from each other at the same time.

[0053] The visual recognition mechanism is arranged on the crossbeam 41 , and the visual recognition mechanism is arranged as a camera.

[0054] The packaging device 2 includes a second supporting and conveying mechanism 21 and a wrapping and packaging mechanism 23. The second supporting and conveying mechanism 21 is docked with the first supporting and conveying mechanism 11 and is used to receive the tire after the positioning device 1 adjusts the position. The second supporting and conveying mechanism 21 is used to support and convey the tire; the wrapping and packaging mechanism 23 is used to wrap the packaging film around the tire.

[0055] Specifically, the structure of the second supporting and conveying mechanism 21 is the same as that of the first supporting and conveying mechanism 11; specifically, the packaging device 2 also includes a second centering clamping and rotating mechanism, the structure of the second centering clamping and rotating mechanism is the same as that of the first centering clamping and rotating mechanism, and the crossbeam 41 of the second centering clamping and rotating mechanism is arranged on the top of the support frame 31 of the second supporting and conveying mechanism 21.

[0056] Specifically, a fixing frame 231 is arranged on the second supporting and conveying mechanism 21, and the fixing frame 231 is arranged in a C shape; a plurality of supporting rollers 32 pass through the opening of the C-shaped fixing frame 231 along the arrangement direction, and the lifting frame 33 also passes through the C-shaped opening of the fixing frame 231. The wrapping and packaging mechanism 23 is arranged on the second supporting and conveying mechanism 21, and the wrapping and packaging mechanism 23 includes a C-shaped frame 232 rotating on the fixing frame 231, a plurality of active rollers 234 rotatably connected to the fixing frame 231, and a packaging film quick-change assembly 233 detachably connected to the C-shaped frame 232; the packaging film roll is installed on the packaging film quick-change assembly 233, and a plurality of active rollers 234 are arranged around the C-shaped frame 232 and clamp the C-shaped frame 232. The rotation of the active rollers 234 can drive the C-shaped frame 232 to rotate around its own axis. During the rotation of the C-shaped frame 232, the packaging film on the packaging film roll is continuously wrapped around the tire to achieve the packaging of the tire.

[0057] Specifically, the packaging film quick-change assembly 233 includes a fixed column 2331 detachably connected to the C-shaped frame 232, a rotating column 2332 sleeved outside the fixed column 2331 and rotatably connected to the fixed column 2331, a plurality of expansion pieces 2333 arranged around the rotating column 2332, and a plurality of elastic members 2338 arranged on the rotating column 2332. The axial direction of the fixed column 2331 is parallel to the axial direction of the C-shaped frame 232, the length direction of the expansion piece 2333 is arranged along the axial direction of the rotating column 2332, the plurality of expansion pieces 2333 are evenly arranged around the axis of the rotating column 2332, and the side of the expansion piece 2333 close to the rotating column 2332 is embedded in the rotating column 2332 and can slide in the rotating column 2332 along the radial direction of the rotating column 2332. Each expansion piece 2333 corresponds to at least one elastic member 2338. When the packaging film roll is arranged outside the rotating column 2332 and contacts the side of multiple expansion pieces 2333 away from the rotating column 2332, the elastic member 2338 is squeezed and applies an elastic force to the expansion piece 2333 away from the axis of the rotating column 2332.

[0058] When the packaging film roll is installed outside the rotating column 2332, the packaging film roll pushes the expansion piece 2333 to slide in the direction close to the axis of the rotating column 2332, so that the expansion piece 2333 squeezes the elastic member 2338. When the packaging film roll is completely sleeved on the outside of the rotating column 2332, under the action of the elastic member 2338, multiple expansion pieces 2333 are simultaneously pressed against the inner side of the packaging film roll under the action of the elastic member 2338, so that the packaging film roll is limited outside the rotating column 2332. There is no need to set up other limiting structures to achieve the installation of the packaging film roll; and when removing the packaging film roll, it is only necessary to use manpower to pull the packaging film roll out from the outside of the rotating column 2332 along the axis direction of the rotating column 2332, so that the disassembly operation is also convenient and quick.

[0059] Specifically, a retaining ring 2334 is provided on the end of the rotating column 2332 close to the C-shaped frame 232 and is sleeved on the outside of the fixed column 2331, and a fixing ring 2335 is provided on the end of the rotating column 2332 away from the retaining ring 2334 and is sleeved on the outside of the fixed column 2331; the diameter of the retaining ring 2334 is larger than the diameter of the rotating column 2332, so as to block the packaging film roll when installing the packaging film roll, and prevent the operator from pushing the packaging film roll to contact the C-shaped frame 232. The fixing ring 2335 is arranged to be coaxial with the rotating column 2332 and has a diameter smaller than the inner diameter of the packaging film roll, so that the packaging film roll can smoothly pass through the fixing ring 2335 when installing.

[0060] Specifically, two clamping plates 23331 are fixedly connected at both ends of the part of the expansion piece 2333 embedded in the rotating column 2332, and clamping grooves 2339 are provided on the inner side of the retaining ring 2334 and the inner side of the fixing ring 2335. The two clamping plates 23331 are respectively inserted into the two clamping grooves 2339. The clamping plates 23331 can slide in the clamping grooves 2339 along the radial direction of the rotating column 2332 to prevent the clamping plates 23331 from hindering the sliding of the expansion piece 2333; through the cooperation between the clamping plates 23331 and the clamping grooves 2339, the expansion piece 2333 can be prevented from detaching from the rotating column 2332 outward.

[0061] Specifically, an inclined surface is provided at one end of the expansion piece 2333 away from the retaining ring 2334, and the end of the inclined surface away from the retaining ring 2334 is inclined toward the direction close to the axis of the rotating column 2332. By providing the inclined surface on the expansion piece 2333, it is easier to put the packaging film roll outside the multiple expansion pieces 2333 when installing the packaging film roll.

[0062] Specifically, the outer side of the fixing ring 2335 is provided with an inclined surface, and the side of the inclined surface away from the retaining ring 2334 is inclined toward the direction close to the axis of the rotating column 2332.

[0064] Specifically, thrust bearings may be provided between the pressure ring 2337 and the fixed ring 2335 and between the limiting ring 2336 and the retaining ring 2334 to improve the smoothness of the rotation of the rotating column 2332 outside the fixed column 2331 .

Specifically, the elastic member 2338 is arranged as a spring.

[0068] Embodiment 2: A stretch film packaging machine, combined with the attached Fig.11 -Attached Fig.13 The difference between this embodiment and the first embodiment is that the packaging device 2 also includes a tape adsorption and cutting mechanism 24, which includes a fixed seat 241, a tape seat 242 arranged on the fixed seat 241, a cutter 244 arranged on the fixed seat 241 for cutting the tape, a pressure roller 243 arranged on the fixed seat 241, an adsorption seat 249 arranged between the cutter 244 and the pressure roller 243, and an air suction pipe connected to the adsorption seat 249. The tape holder 242 is rotatably connected to the fixed seat 241, the tape roll is fixed on the tape holder 242 and the tape is unwound by the rotation of the tape holder 242; the pressure roller 243 is arranged between the cutter 244 and the tape roll to press the tape onto the tire; the adsorption seat 249 is arranged between the cutter 244 and the pressure roller 243, and the adsorption seat 249 is provided with adsorption holes, and the tape can be adsorbed on the adsorption seat 249 under the negative pressure of the adsorption holes; the suction pipe is connected to the adsorption seat 249 to provide negative pressure to the adsorption holes.

[0069] When a tire is wrapped and packaged, the cutter 244 moves forward and contacts the tape to cut the tape. At this time, the suction pipe provides negative pressure to the suction hole, so that one end of the tape connected to the tape roll after cutting is adsorbed on the adsorption seat 249. When packaging the next tire, the pressure roller 243 moves forward to push the tape into contact with the tire, thereby achieving the adhesion of the tape to the tire.

[0070] Specifically, the present embodiment further includes a cutting telescopic member 2441, which is disposed on the fixed seat 241 and is used to drive the cutter 244 to move closer to and away from the tape to cut the tape. The cutting telescopic member 2441 is configured as a cylinder, the cylinder body of the cylinder is fixedly connected to the fixed seat 241, and the piston rod is fixedly connected to the cutter 244, so that the expansion and contraction of the piston rod in the cylinder body can drive the cutter 244 to move closer to and away from the tape, so that the cutting operation of the tape can be achieved through the movement of the cutter 244.

[0071] Specifically, the adsorption seat 249 is fixed on the cutter 244 so that the adsorption seat 249 can move with the cutter 244 to adsorb the tape cut by the cutter 244 on the adsorption seat 249. When the cutter 244 moves toward the tape to cut the tape, the adsorption seat 249 is also driven by the cutter 244 to approach the tape. When the cutter 244 contacts the tape to cut the tape, the adsorption seat 249 is close to the tape, so that one end of the tape connected to the tape roll after cutting can be adsorbed on the adsorption seat 249 under the negative pressure in the adsorption hole.

[0072] Specifically, the present embodiment further comprises a compression telescopic member 2431 and a compression seat 2432, wherein the compression telescopic member 2431 is arranged on the fixed seat 241; the pressure roller 243 is rotatably connected to the compression seat 2432, and the compression telescopic member 2431 is connected to the compression seat 2432 to drive the pressure roller 243 to approach and move away from the tire through the compression seat 2432. Specifically, the compression telescopic member 2431 is arranged as a cylinder, the cylinder body of the compression telescopic member 2431 is fixedly connected to the fixed seat 241, the piston rod is fixedly connected to the compression seat 2432, and the compression seat 2432 is driven to slide by the expansion and contraction of the piston rod on the cylinder body, thereby driving the pressure roller 243 to approach and move away from the tire. Since the pressure roller 243 is located between the tape holder 242 and the adsorption seat 249, when the tape is adsorbed on the adsorption seat 249, the pressure roller 243 can push the tape between the adsorption seat 249 and the tape holder 242 to move toward the tire until the tape is attached to the tire, and then the adsorption seat 249 releases the adsorption of the tape, and as the tire is packed, the pressure roller 243 packs the tape outside the tire.

[0073] Specifically, in this embodiment, the sliding direction of the cutter 244 and the sliding direction of the pressure roller 243 are horizontal and parallel to each other.

[0074] Specifically, the present embodiment further includes a lifting seat 245, which drives the fixing seat 241 to move up and down by moving up and down, thereby adjusting the position of the fixing seat 241 according to the size of the tire.
