Description

Technical Field

[0001] The invention relates to the technical field of yogurt production, in particular to an automatic conveying device used for yogurt packaging. Background Art

[0002] Automatic conveying technology after yogurt packaging is an indispensable part of modern dairy production lines. Through automated equipment, packaged yogurt can be efficiently and safely transferred from one process to the next, ensuring production continuity and product quality. However, quality inspection, counting, labeling, coding and other processes are usually carried out during the automatic conveying of yogurt packaging. Therefore, the yogurt packages need to be evenly spaced to facilitate the subsequent automated equipment to accurately locate each package for inspection. At the same time, the product quantity can be accurately counted, which is helpful for inventory management and production planning.

[0003] At present, there are the following disadvantages in conveying yogurt packages: 1. When it is necessary to convey, a conveyor belt is usually used to transport the yogurt packages. During this process, the yogurt packages are uniformly straightened by external clamping, and then the transportation can continue. At this time, continuing to transport will cause the previous yogurt package to fit together with the next one, which will cause the label and inkjet coding equipment to be unable to accurately position, thereby affecting the accuracy and readability of the information, and may cause the yogurt package to be damaged or deformed during subsequent packing and transportation; 2. When conveying the yogurt package, when the yogurt package is clamped and straightened, the conveyor belt below is in operation, causing friction between the conveyor belt and the lower end surface of the yogurt package, thereby causing wear of the material at the bottom of the package, affecting the integrity and appearance of the package, and causing the package to be unstable during transportation, increasing the risk of the package tilting or overturning, and long-term friction will cause wear of the conveyor belt and the clamping device, accelerate equipment aging and increase maintenance costs.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The automatic conveying device for yogurt packaging, through the coordinated use of the set toggle mechanism, the straightening mechanism and the correction mechanism, adopts an integrated operation model of toggle, straightening and correction to ensure the uniform arrangement of the intervals of the yogurt packages during transportation, and comprehensively optimizes the conveying process of the yogurt packages. First, through the first interval limit when the package enters, it is ensured that the yogurt package can maintain an appropriate distance when entering the device. Secondly, a single-sided rolling method is used for preliminary correction, which simplifies the alignment process and reduces the risk of damage. Then, a second precise correction and clamping interval are performed to avoid bottom wear. Finally, the rolling limits on both sides continuously keep the packaging position stable, thereby significantly improving the stability and accuracy of the yogurt package during transportation, greatly reducing the risk of package damage, improving the accuracy of subsequent processes, and comprehensively improving production efficiency and product quality.

[0017] 2. The automatic conveying device for yogurt packaging can implement the first interval limitation on the yogurt packaging when the yogurt packaging enters the device through the set toggle mechanism, ensure the appropriate distance between the packages at the initial stage of transportation, reduce subsequent bonding problems, and reduce collision and friction between packages, thereby reducing the risk of damage to the yogurt packaging.

[0018] 3. The automatic conveying device for yogurt packaging uses a straightening mechanism to perform preliminary straightening of the yogurt package on the transport belt by unilateral rolling, so that the yogurt package can be quickly aligned to one side, simplifying the alignment process. Compared with the bilateral or full contact straightening method, the unilateral rolling reduces the contact area with the package and reduces the risk of package damage.

[0019] 4. The automatic conveying device used for yogurt packaging can perform a second position correction and clamping interval on the yogurt package during the conveying process through the set position correction mechanism, further improving the positioning accuracy of the package and ensuring the accuracy of subsequent processes. In addition, when the yogurt package is clamped, the lower transport belt will not slide in contact with the lower end of the yogurt package, thereby not wearing the lower end surface of the yogurt package, greatly reducing the risk of wear on the bottom of the package.

[0020] 5. The automatic conveying device for yogurt packaging, through the coordinated use of the straightening mechanism and the position correction mechanism, performs rolling limit on both sides of the yogurt package during the conveying process after the yogurt package has been spaced and straightened on both sides. It can continuously maintain the stable position of the yogurt package on the conveyor belt, prevent the yogurt package from shifting or rotating, and further improve the accuracy of subsequent processes.

[0031] See also Figure 1 The side support plate 2 is provided with a straightening mechanism 5 for initially straightening the yogurt package by unilateral rolling, and the side support plate 2 is also provided with a straightening mechanism 6 for cooperating with the straightening mechanism 5 to perform a second straightening and a second clamping interval on the yogurt package.

[0032] See also Figure 1The straightening mechanism 5 includes a straightening portion 51 arranged on the side support plate 2, and the side support plate 2 is also provided with a limiting portion 52 for implementing rolling limiting on both sides of the yogurt package after the second straightening.

[0033] See also Figure 1 The correction mechanism 6 includes a support portion 61 arranged on the side support plate 2 and used to provide planar support for the yogurt package. The support portion 61 is provided with a driving portion 62 and a switching portion 63 cooperating with the driving portion 62. The switching portion 63 is provided with a contact portion 64 for plane clamping and rolling conveying the yogurt package. The driving portion 62 cooperates with the switching portion 63 to switch the state of the contact portion 64. The support portion 61 is also provided with a transmission portion 65 for providing power to the contact portion 64 through the main body 41.

[0034] See also Figure 1 , Figure 2 and Figure 3 The main body 41 includes a conveying belt 411, a toothed belt 412, a first support plate 413, a torsion spring rod 414, a matching rod 415 and a baffle 416. The front and rear symmetrical driving rollers 3 are jointly sleeved with a conveying belt 411 located between the left and right symmetrical side support plates 2. The left and right symmetrical side support plates 2 are each provided with a toothed belt 412 sleeved on the front and rear symmetrical driving rollers 3 on the opposite sides. An L-shaped first support plate 413 is fixedly installed on the front side of the upper end face of the side support plate 2. A torsion spring rod 414 is rotatably installed on the upper end face of the horizontal section of the first support plate 413. A matching rod 415 is fixedly installed through the torsion spring rod 414. A baffle 416 is fixedly installed on the ends of the left and right symmetrical matching rods 415 that are close to each other.

[0035] See also Figure 1 and Figure 3 The matching part 42 includes a first shaft rod 421, a first gear 422 and a lever 423. The vertical section of the first support plate 413 is equipped with the first shaft rod 421 through a bearing. The first shaft rod 421 is fixedly sleeved with a first gear 422 meshingly connected to the corresponding toothed belt 412. The lever 423 is fixedly installed at one end of the first shaft rod 421 away from the corresponding torsion spring rod 414, and the lever 423 is in contact with the matching rod 415.

[0036] During specific operation, when the yogurt packages need to be transported, the driving roller 3 is first rotated by an external motor to make the driving rollers 3 on the front and rear sides rotate with the transport belt 411. At this time, the yogurt packages to be transported can be placed at different intervals at the front end of the transport belt 411, and then the yogurt packages are moved to the baffle 416 under the transportation of the transport belt 411, and the baffles 416 on both sides will block the yogurt packages.

[0037] At this time, the rotation of the driving rollers 3 on the front and rear sides will drive the toothed belt 412 to rotate synchronously with the conveying belt 411, and the first gear 422 will drive the first shaft rod 421 to rotate under the action of the toothed belt 412, so that the lever 423 will rotate with the first shaft rod 421 as the center, and when the upper end of the lever 423 moves to the matching rod 415, it will push it forward, and the matching rod 415 will rotate with the torsion spring rod 414 as the center point, so that the baffles 416 on both sides rotate backwards at the same time, thereby opening the transport channel, and the yogurt package can continue to move backwards following the conveying belt 411.

[0038] When the upper end of the lever 423 moves to a point where it is no longer in contact with the mating rod 415, the mating rod 415 quickly returns to its original position under the action of the torsion spring rod 414, and the baffles 416 on both sides block the next yogurt package, thereby implementing the first interval limit on the yogurt package when the yogurt package enters the device, thereby ensuring the appropriate distance between the packages at the initial stage of transportation and reducing subsequent bonding problems.

[0039] See also Figure 2 , Figure 3 and Figure 4 The straightening portion 51 includes a right-angled trapezoidal block 511, a first groove 512, a second shaft 513, a first roller 514 and a third shaft 515. A right-angled trapezoidal block 511 located behind the first support plate 413 is fixedly installed on the side support plate 2. The front side inclined surfaces of the right-angled trapezoidal block 511 symmetrically form an eight-shaped shape. A first groove 512 is opened on the inclined surface of the right-angled trapezoidal block 511 on the right side. A plurality of second shafts 513 are installed in the first groove 512 in a linear array through a bearing. The plurality of second shafts 513 are connected by a first belt transmission. A first roller 514 is fixedly sleeved on the second shaft 513. A third shaft 515 is installed in the right-angled trapezoidal block 511 through a bearing. The third shaft 515 is connected to one of the second shafts 513 through a first bevel gear set. A second gear meshing with the corresponding toothed belt 412 is fixedly sleeved on the second shaft 513.

[0040] During specific operation, when the yogurt package reaches the inclined surface of the right-angled trapezoidal stoppers 511 on both sides, if the yogurt package is in an inclined state at this time, it cannot move backward continuously in the area formed by the inclined surfaces in an eight-character shape. At this time, the second gear cooperating with the toothed belt 412 will rotate the third shaft rod 515, and the third shaft rod 515 will rotate the corresponding second shaft rod 513 through the first bevel gear set, and drive all the second shaft rods 513 to rotate backward synchronously through the first belt, so that the first roller 514 rotates forward in the first groove 512. At this time, the non-passing yogurt package will contact the first roller 514, and the position of the yogurt package will be adjusted under the rotation of the first roller 514, so that the yogurt package can enter between the horizontal planes where the right-angled trapezoidal stoppers 511 on both sides approach each other, and the conveyor belt 411 will carry the yogurt package to move backward continuously. In this way, the yogurt package on the conveyor belt 411 is initially righted by single-sided rolling, so that the yogurt package can be quickly aligned to one side, and the contact area with the package is reduced, reducing the risk of package damage.

[0044] Please refer to Figure 1 、 Figure 6 and Figure 7 As shown in, the contact part 64 includes a third roller 641 and a clamping block 642. A number of third rollers 641 are installed in the transport frame 633 through bearings in a linear array. The third rollers 641 are connected by a third belt. Clamping blocks 642 located between adjacent third rollers 641 are fixedly installed on the side wall of the clamping plate 634 close to the corresponding transport frame 633.

[0045] Please refer to Figure 1 、 Figure 6 and Figure 7 As shown in, the transmission part 65 includes a support frame 651, a spline shaft 652, an L-shaped support plate 653, a spline sleeve 654 and a sixth shaft rod 655. A support frame 651 is fixedly installed on the upper end of the support block 613. A spline shaft 652 is installed between the symmetrically arranged support frames 651 through bearings. An L-shaped support plate 653 is fixedly installed on the upper end surface of the transport frame 633. The upper end of one of the third rollers 641 penetrates through the horizontal section of the L-shaped support plate 653 and is connected to it through a bearing. A spline sleeve 654 slidably connected to the spline shaft 652 is installed in the vertical section of the L-shaped support plate 653 through a bearing. The spline sleeve 654 is connected to the corresponding third roller 641 through a second bevel gear set. A sixth shaft rod 655 is installed on the support frame 651 through a bearing. The sixth shaft rod 655 is connected to the spline shaft 652 through a fourth belt. A third gear meshing with the corresponding toothed belt 412 is fixedly sleeved on the sixth shaft rod 655.

[0046] During specific operation, when the transport belt 411 moves the yogurt package to the supporting plate 612, the push on the yogurt package disappears, and then the motor 622 is started to rotate the fourth shaft rod 621 on the right side counterclockwise, and the fourth shaft rod 621 on the right side first rotates the fifth shaft rod 623 through the second belt, and then the fifth shaft rod 623 rotates the fourth shaft rod 621 on the left side clockwise through the first transmission gear set, so that the fourth shaft rods 621 on the left and right sides rotate synchronously in opposite directions.

[0047] Taking the fourth shaft rod 621 on the right side as an example, the fourth shaft rod 621 will rotate counterclockwise with the rocker arm 624. At this time, the limiting slide rail 631 will limit the moving direction of the transport frame 633 and the clamping plate 634, and the rocker arm 624 will cooperate with the slide groove 625 and the slide rod 635 to pull the clamping plate 634 to the left and push the transport frame 633 to the right, so that the clamping plate 634 and the transport frame 633 are synchronously close, and the clamping plate 634 carries the clamping block 642 to pass between the adjacent third rollers 641 in the transport frame 633. At the same time, the fourth shaft rod 621 on the other side is similar, so that the clamping plates 634 on both sides are synchronously close to each other, so that the yogurt package on the supporting plate 612 is corrected for the second time through the clamping blocks 642 on both sides, so as to ensure the accuracy of the yogurt package position.

[0048] When the clamping block 642 clamps and straightens the yogurt package, the conveying belt 411 below will not slide in contact with the lower end of the yogurt package, thereby not wearing the lower end surface of the yogurt package, greatly reducing the wear of the bottom of the package.

[0049] After the yogurt package is corrected and straightened, when the yogurt package needs to be transported backward, the motor 622 is started in reverse to rotate the fourth shaft rod 621 on the right side clockwise, thereby rotating the rocker arm 624 clockwise, and the fourth shaft rod 621 on the other side will rotate counterclockwise, so that the transport frame 633 and the clamping plate 634 will move away from each other synchronously, and the transport frames 633 on both sides will approach the yogurt package synchronously, and when the transport frame 633 carrying the third roller 641 contacts the yogurt package, the motor 622 is stopped.

[0050] At this time, the rotation of the toothed belt 412 will drive the sixth shaft 655 to rotate through the third gear, and the sixth shaft 655 will synchronously rotate the spline shaft 652 through the fourth belt. At the same time, the spline shaft 652 rotates the spline sleeve 654, and rotates the corresponding third roller 641 through the second bevel gear set, and then all the third rollers 641 are synchronously rotated through the third belt, so that the third rollers 641 contacting the yogurt package rotate backwards at the same time, thereby transporting the yogurt package backwards until the yogurt package is transferred from the supporting plate 612 to the transport belt 411 again, so that the yogurt package is subjected to a second position correction and a second clamping interval during the transportation process, thereby further improving the positioning accuracy of the package and ensuring the accuracy of subsequent processes.

[0051] See also Figure 2 The limiting portion 52 includes a limiting block 521 and a second roller 522. The limiting block 521 located behind the right-angle trapezoidal stopper 511 is fixedly installed on the side support plate 2. A side wall of the left and right symmetrical limiting blocks 521 close to each other is rotatably installed with a plurality of second rollers 522 in a linear array through a bearing seat.

[0052] During specific operation, the yogurt package that reaches the conveyor belt 411 again will continue to move backwards. At this time, several second rollers 522 on both sides of the rear will roll and limit the two sides of the yogurt package during the conveying process to continuously maintain the position of the yogurt package on the conveyor belt stable, prevent the yogurt package from shifting or rotating, and further improve the accuracy of subsequent processes.
