Description

Technical Field

[0001] The invention relates to a carton stacking technology, and in particular to an automatic packaging and stacking mechanism for finished carton boxes. Background Art

[0002] Cartons are common packaging materials. After the items are packaged, they generally need to be stacked.

[0003] Common palletizing mechanisms mainly use adsorption transfer, clamping transfer and lifting transfer to transfer the finished packaged cartons. During adsorption transfer, the adsorption plate is easily affected by the flatness of the carton surface, and the carton surface is affected by its material, resulting in its own limited load-bearing capacity. Therefore, during the transfer process, the carton is prone to detachment or damage. During clamping transfer, the uneven placement of items inside the carton causes the center of gravity of the carton to shift, so that during the clamping transfer process, the overall position of the carton is deflected, which makes it easy for the position to shift too much during stacking, resulting in poor overall stability of the carton after palletizing. During lifting transfer, although the process is stable, the bottom support plate is prone to scratch the carton below when unloading, and when the carton is detached from the support plate, one end of the carton first rotates downward to contact the carton below, resulting in its position after stacking shifting, making it impossible to align the cartons when stacking, resulting in poor stability of the cartons after palletizing.

[0004] A Chinese patent with announcement number CN218706924U discloses a stacking mechanism for processing packaging cartons. When transferring cartons, the cartons are transferred by cooperating between a bottom lifting plate and an upper limit frame. Although the transfer stability is good, when placing the cartons, a gap needs to be provided between the limit frame and adjacent cartons, so that when placing the cartons, the intervals between adjacent cartons are still large. When the stacking height of the cartons is high, the overall structure is easily unstable, increasing the risk of collapse. In addition, excessive gaps also affect the utilization rate of the storage space and reduce the stacking efficiency. Therefore, both the present application and the prior art have the problem of poor stability due to poor stacking neatness of the cartons. Summary of the invention

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] See also Figure 1-Figure 6, an automatic packaging and stacking mechanism for finished cartons, comprising a roller conveyor 1 and a carrying platform 101 arranged at the conveying end thereof, a grabbing unit is arranged on one side of the roller conveyor 1, a controller 102 is arranged outside the roller conveyor 1, the grabbing unit comprises a base 2, a rotating seat 21 is arranged on the base 2, a plurality of groups of extension arms 22 are rotatably connected to the rotating seat 21 in sequence, and a connecting block 23 is rotatably connected to the end of the extension arm 22;

[0032] It should be noted that, through the setting of the base 2, the extension arm 22 can be rotated in the horizontal direction, and through the rotation setting between the multiple groups of extension arms 22, the multiple groups of extension arms 22 can be relatively rotated in the vertical direction. At the same time, the connection block 23 is rotatably connected to the end of the extension arm 22, so that during the carton transportation process, the carton can be accurately transported through multi-dimensional activities;

[0033] It needs to be further explained that the mechanical arm composed of the above-mentioned extension arm 22, connecting block 23 and rotating seat 21 is consistent with the structure and principle of the existing mechanical arm. The rotating seat 21 is driven by a motor, and the adjacent extension arms 22 are driven by a cylinder. Moreover, the connecting block 23 that is rotatably connected to the extension arm 22 is also driven by a motor. These are all existing technologies and will not be described in detail here.

[0034] The bottom of the connecting block 23 is fixedly connected to a mounting plate 3, and both sides of the bottom surface of the mounting plate 3 are symmetrically slidably connected with clamping plates 31, and the surfaces of the two clamping plates 31 facing each other are connected to multiple groups of active rubber rollers 32 by rotating from top to bottom. The active rubber rollers 32 are driven by a motor, and a supporting groove 33 is provided at the bottom of the surface of the clamping plate 31. The inner side surface of the supporting groove 33 is slidably connected with a receiving plate 34. The two clamping plates 31 are installed with a first electric rod 36 on the side away from each other, and the telescopic end of the first electric rod 36 is fixedly connected to the receiving plate 34. The first electric rod 36 can drive the receiving plate 34 to slide back and forth along the inner side surface of the supporting groove 33. At the same time, with the cooperation of the supporting groove 33, the bearing strength of the receiving plate 34 can be greatly improved. A driving unit is provided on the mounting plate 3, and the driving unit is used to drive the clamping plates 31 on both sides to perform synchronous reverse movement.

[0035] In this embodiment, the driving unit includes an installation cavity opened inside the installation plate 3. The bottom of the installation cavity is rectangular and symmetrically provided with two groups of guide grooves. The inner side surfaces of the guide grooves are slidably connected with guide blocks 35. The two guide blocks 35 in the same group are symmetrically installed on the same clamping plate 31. The inner side surface of the installation cavity is rotatably connected with a first gear 351. The first gear 351 is driven by a motor. The two diagonal guide blocks 35 are respectively provided with first racks 352, and the two first racks 352 are respectively meshed with the two sides of the first gear 351.

[0036] In this embodiment, a long plate 4 is installed at the bottom of the mounting plate 3, and a movable cavity is opened inside the long plate 4. The inner side surface of the movable cavity is rectangular and symmetrically opened with two groups of straight grooves. The inner side surface of the straight groove is slidably connected with a slider 41. The bottoms of the two sliders 41 in the same group are fixedly connected with the same auxiliary plate 42. The surface of the auxiliary plate 42 is rotatably connected with multiple groups of driven rubber rollers 43 from top to bottom. The inner side surface of the movable cavity is rotatably connected with a second gear 44. The second gear 44 is driven by a motor. Second racks 45 are respectively arranged on the two diagonal sliders 41, and the two second racks 45 are respectively meshed on both sides of the second gear 44.

[0037] In this embodiment, an auxiliary groove 46 corresponding to the supporting groove 33 is opened at the bottom of the side of the auxiliary plate 42, and the inner side surface of the auxiliary groove 46 is slidably connected with an auxiliary support plate 47. A second electric rod 48 is fixedly installed on the side where the two auxiliary plates 42 are away from each other, and the telescopic end of the second electric rod 48 is fixedly connected to the auxiliary support plate 47. The auxiliary support plate 47 can be driven by the second electric rod 48 to slide smoothly along the inner side surface of the auxiliary groove 46. At the same time, through the cooperation of the auxiliary groove 46, the supporting stability of the auxiliary support plate 47 can be better.

[0038] During the process of stacking cartons, the mounting plate 3 can be moved to the top of the cartons placed on the carrying platform 101 through the cooperation between the rotating seat 21, the multiple extension arms 22 and the connecting block 23, and then the mounting plate 3 is driven by the extension arm 22 to move vertically downward from the top of the carton, and the clamping plate 31 below it is driven to move downward, so that the bottom end of the clamping plate 31 extends to below the top of the carton, and then the first gear 351 drives the first racks 352 on both sides to move synchronously towards each other, so that the clamping plates 31 on both sides are close to each other, so that the active rubber roller 32 on the clamping plate 31 contacts the surface of the carton, and in the same way, the auxiliary plates 42 on both sides are driven to move close to each other, and the driven rubber rollers 43 provided on the auxiliary plates 42 on both sides are in contact with the surface of the carton, so that the position of the carton can be corrected and fixed under the cooperation between the clamping plates 31 and the auxiliary plates 42;

[0039] After the active rubber roller 32 is in stable contact with the surface of the carton, the motor drives it to rotate, so that the active rubber roller 32 can drive the carton to move upward, so that the carton gradually leaves the load-bearing platform 101 and moves to the top of the receiving plate 34. After that, the first electric rod 36 and the second electric rod 48 respectively drive the receiving plates 34 on both sides to approach each other and drive the auxiliary supporting plates 47 on both sides to approach each other. Then, the active rubber roller 32 drives the carton to move downward to contact the upper surface of the receiving plate 34 and the auxiliary supporting plate 47, so that the carton can be stably loaded, so that the carton has better stability during transportation.

[0040] When the carton is conveyed to the designated position, the extension arms 22 cooperate with each other so that the clamping plate 31 is located above the surrounding cartons. Then, the first electric rod 36 and the second electric rod 48 respectively drive the receiving plates 34 on both sides to approach each other and drive the auxiliary supporting plates 47 on both sides to move away from each other, so that they no longer carry the cartons. At this time, the position of the clamping plate 31 is adjusted again through the cooperation of the extension arms 22 so that its bottom is flush with the top of the surrounding cartons. Then, the active rubber roller 32 drives the carton to move slowly downward, so that the carton can fall smoothly at the designated position without easily affecting the surrounding cartons.

[0041] Embodiment 2:

[0042] See also Figure 6 This embodiment provides a technical solution based on the above embodiment: the guide block 35 connected to the first rack 352 and the slider 41 connected to the second rack 45 are fixedly connected to the outside of the extension rod 5, and the surface of the extension rod 5 is provided with a guide groove 51. The guide groove 51 is arranged in a convex shape, and the inner side surface of the guide groove 51 is slidably connected with a pressure relief block 52, a buffer spring 53 is connected between the pressure relief block 52 and the inner wall of the guide groove 51, a pressure sensor 54 is arranged between the buffer spring 53 and the pressure relief block 52, and the pressure sensor 54 is electrically connected to the controller 102.

[0043] It should be noted that the first rack 352 and the second rack 45 are respectively fixedly connected to the pressure relief blocks 52 at corresponding positions.

[0044] In addition, the motor driving the first gear 351, the motor driving the second gear 44, and the first electric rod 36 and the second electric rod 48 are all electrically connected to the controller 102. During operation, the pressure sensor 54 transmits the detected pressure signal to the controller 102. The controller 102 controls the rotation of the motor and the movement of the first electric rod 36 and the second electric rod 48 according to the signal to ensure that the carton is evenly stressed during movement, avoiding deformation or damage of the carton due to uneven pressure, thereby improving overall handling efficiency and safety.

[0045] Embodiment 3:

[0046] See also Figure 3 This embodiment provides a technical solution based on the above embodiment: the bottom surface of the receiving plate 34 and the bottom surface of the auxiliary support plate 47 are both fixedly connected with the auxiliary pressing plate 6.

[0047] It should be supplemented that the bottom surface of the auxiliary pressure plate 6 is flush with the bottom surfaces of the clamping plate 31 and the auxiliary plate 42, so that when the bottom surface of the clamping plate 31 contacts the upper surface of the surrounding carton, the bottom surfaces of the auxiliary pressure plate 6 and the auxiliary plate 42 both contact the upper surface of the carton, thereby cooperating to limit the position of the surrounding straight lines.

[0048] In addition, the auxiliary pressing plate 6 connected to the receiving plate 34 is arranged at one end of the bottom surfaces of the receiving plates 34 on both sides away from each other, and the auxiliary pressing plate 6 connected to the auxiliary supporting plate 47 is arranged at one end of the bottom surfaces of the auxiliary supporting plates 47 on both sides away from each other.

[0049] During the process of placing cartons, when the clamping plate 31 moves to the point where the bottom is flush with the tops of the surrounding cartons, the bottom of the clamping plate 31, the bottom of the auxiliary plate 42 and the bottom of the auxiliary pressure plate 6 are all in contact with the upper surfaces of the surrounding cartons, thereby playing a certain fixing role on the surrounding cartons, making it difficult for the cartons to be placed to affect the surrounding cartons during the placement process, and making the stacked cartons more stable.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
