Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard processing equipment, specifically relating to a cardboard sorting mechanism and a packing and palletizing machine. Background Technology

[0002] Cardboard boxes are a widely used packaging container, typically made of corrugated cardboard. They offer advantages such as low cost, light weight, ease of processing, and recyclability, making them widely used in product packaging across various industries. Cardboard box packing and palletizing machines, as key equipment for achieving packaging automation, can bind and pack processed cardboard boxes, and then stack them in an orderly manner to form pallets, greatly improving warehousing and transportation efficiency and reducing labor costs.

[0003] In existing technologies, most carton palletizers have significant shortcomings in their arrangement of each layer of cartons during the palletizing preparation stage. On one hand, traditional arrangement methods are relatively simple, often only capable of simple linear arrangements. In scenarios requiring tight stacking to save space, or where specific stack shapes are needed for easy handling and identification, these traditional methods fail to meet the diverse needs of users. On the other hand, existing arrangement methods lack flexibility, requiring significant time for manual setup and adjustments, severely impacting production efficiency. Utility Model Content

It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0043] Please refer to the following: Figures 1 to 8The present invention provides a cardboard sorting mechanism. The cardboard sorting mechanism includes a conveyor frame 1, a first baffle 3, a second baffle 4, and a transverse push assembly 5. The conveyor frame 1 is used to transport cardboard. The first baffle 3 is slidably connected to the middle of the conveyor frame 1 in a vertical direction. The second baffle 4 is slidably connected to the conveyor frame 1 in a vertical direction and is located behind the first baffle 3. The transverse push assembly 5 is located between the first baffle 3 and the second baffle 4, and is positioned close to the second baffle 4. The transverse push assembly 5 includes a first transverse push plate 52 and a second transverse push plate 53 slidably connected to the conveyor frame 1, and the first transverse push plate 52 and the second transverse push plate 53 are arranged opposite to each other. Both the first baffle 3 and the second baffle 4 can be raised and lowered to restrict the movement of the cardboard. Both the first transverse push plate 52 and the second transverse push plate 53 can slide in a direction perpendicular to the movement of the cardboard to push the cardboard laterally. The first baffle 3, the second baffle 4, and the first transverse push plate 52 and the second transverse push plate 53 cooperate with each other to arrange the cardboard.

[0044] The cardboard sorting mechanism provided in this embodiment can achieve the following: Figure 6 The various cardboard arrangement methods shown below are as follows: Figure 6 The specific arrangement process is described using the double-row stack shown in diagram d as an example. (See [reference]). Figure 7 For ease of description, the direction of the cardboard coming from is defined as "front" and the direction of going out is defined as "back". In the reset state, both the first baffle 3 and the second baffle 4 are in the raised state to intercept the cardboard in time to control the running rhythm of the cardboard. The first horizontal push plate 52 and the second horizontal push plate 53 are respectively close to the two sides of the conveyor frame 1. The conveyor frame 1 is used to receive the packaged cardboard and drive the cardboard to move backward. The raised first baffle 3 is used to intercept the cardboard. Subsequent cardboard will accumulate in front of the first baffle 3 along the same path to achieve the longitudinal arrangement of the cardboard (see step S1). When the number of cardboard in front of the first baffle 3 reaches the set number, the first baffle 3 lowers and releases the cardboard. The cardboard continues to run to the front of the second baffle 4 while maintaining the longitudinally arranged stack shape. The raised second baffle 4 intercepts the cardboard again (see step S2). At the same time, the first horizontal push plate 52 is activated to push the longitudinally arranged cardboard horizontally to the second horizontal push plate 53. At push plate 53, the arrangement of the first column of cardboard is completed (see step S3); then the first horizontal push plate 52 is reset, and at the same time, the vertically arranged cardboard accumulates again in front of the raised first baffle 3 (see step S4). The first baffle 3 descends to allow the cardboard to move between the first horizontal push plate 52 and the first column of cardboard, completing the arrangement of the second column of cardboard. At this time, the first horizontal push plate 52 and the second horizontal push plate 53 start simultaneously and move towards each other to align and center the two sides of the double-column stack (see step S5). Then the second baffle 4 descends to allow the arranged stack to continue to the subsequent stacking process.

[0045] When needed Figure 6 When the cardboard is arranged as shown in f, please refer to the specific arrangement process. Figure 8 , different from the above double-column stack arrangement process, this mixed horizontal and vertical arrangement method requires the assistance of an external rotating device or manual operation to rotate the cardboard to the required running direction. Specifically, the first column consists of two horizontally placed cardboard sheets, and the arrangement process is the same as that of the above double-column stack. The second column consists of a vertically placed cardboard sheet, which needs to be adjusted to the vertical direction by an external rotating device or manual operation before it reaches the first baffle 3, ensuring that after the first baffle 3 descends, this cardboard sheet can enter between the first column of cardboard sheets and the first horizontal pushing plate 52 along the set direction, facilitating the subsequent centering arrangement of the cardboard sheets by the cooperation of the first horizontal pushing plate 52 and the second horizontal pushing plate 53.

[0046] Compared with the prior art, the lifting and lowering movements of the first baffle 3 and the second baffle 4 can flexibly control the conveying rhythm of the cardboard sheets. The raised first baffle 3 can accumulate the cardboard sheets and complete the vertical arrangement of the cardboard sheets, and the raised second baffle 4 can cooperate with the horizontal pushing assembly 5 to complete the horizontal arrangement of the cardboard sheets. At the same time, the first horizontal pushing plate 52 and the second horizontal pushing plate 53 can also make the stack centered and aligned on both sides by moving towards each other. This cardboard sheet sorting mechanism, through the mutual cooperation and coordinated work of the first baffle 3, the second baffle 4, the first horizontal pushing plate 52, and the second horizontal pushing plate 53, makes the entire cardboard sheet arrangement process more efficient and orderly, and can achieve various different cardboard sheet arrangement methods, such as the "one" shape, the "cross" shape, the "abundant" shape, and the "well" shape, etc. It not only improves the work efficiency but also has the advantages of a compact structure, simple operation, and strong applicability, and is suitable for large-scale production environments.

[0047] In addition, the composition structure of this cardboard sheet sorting mechanism is relatively simple, mainly including a conveying frame 1, two baffles, and two horizontal pushing plates. This simple structural design not only reduces the manufacturing cost but also makes maintenance and upkeep more convenient during daily use. The functions of each component are clear, and it is easy to troubleshoot and repair when a failure occurs, reducing the equipment downtime and improving the reliability and service life of the equipment.

[0048] Furthermore, for the convenience of processing, the conveying frame 1 can be divided into two parts: a front conveying frame 1 and a rear conveying frame 1. The first baffle 3 is arranged on the front conveying frame 1, and the second baffle 4 and the horizontal pushing assembly 5 are arranged on the rear conveying frame 1. To ensure the continuous operation of the cardboard sheets, the front conveying frame 1 and the rear conveying frame 1 are closely installed front and back. On this basis, the rollers 2 for conveying the cardboard sheets on the rear conveying frame 1 can be set as double-row short shafts, avoiding the bending of the rollers 2 due to uneven stress during the arrangement process, and improving the bearing capacity and stability of the conveying frame 1.

[0049] More specifically, the bottom of the first push plate 52 and the second push plate 53 are provided with clearance grooves that slide with the roller 2 on the conveyor frame 1. At the same time, the opposite side walls of the two are respectively provided with reinforcing ribs, which increases the overall rigidity of the first push plate 52 and the second push plate 53 and ensures the stability when pushing the cardboard.

[0050] In some embodiments, the aforementioned transverse push assembly 5 may adopt the following... Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The transverse push assembly 5 also includes a transverse push bracket 51 and two sets of drive devices 54. The transverse push bracket 51 is connected above the conveyor frame 1. The drive device 54 includes two pulleys 541, a transmission belt 542 and a drive component 543. The two pulleys 541 are rotatably connected to both ends of the transverse push bracket 51. The transmission belt 542 is sleeved on the outer periphery of the two pulleys 541. The drive component 543 is connected to the transverse push bracket 51 and connected to one of the pulleys 541. The upper end of the first transverse push plate 52 and the upper end of the second transverse push plate 53 are connected to the two transmission belts 542 one by one.

[0051] The transverse push bracket 51 is mounted above the conveyor frame 1, providing a reliable mounting platform for the drive unit 54. Both drive units 54 are located on the upper part of the transverse push bracket 51, providing sufficient sliding stroke for the two transverse push plates and optimizing the structural layout of the transverse push assembly 5. The two transmission belts 542 are parallel to each other and centrally located, enabling the two transverse push plates to move stably towards each other.

[0052] On the other hand, each drive unit 54 is equipped with an independent drive component 543, which allows the two sets of drive units 54 to be controlled independently to achieve different motion modes and speeds. The movement speed, direction and stroke of the first horizontal push plate 52 and the second horizontal push plate 53 can be flexibly adjusted according to the actual cardboard arrangement requirements to meet diverse production process requirements.

[0053] In some possible embodiments, guide rails 511 are connected to both sides of the horizontal pusher 51. The guide rails 511 extend perpendicular to the running direction of the cardboard. Two first sliders 521 are provided on the first horizontal pusher plate 52 and the second horizontal pusher plate 53 respectively. The two first sliders 521 are slidably connected to the two guide rails 511 in a one-to-one correspondence.

[0054] Specifically, the two sides of the horizontal pusher 51 are equipped with two long support rods arranged along the width direction of the conveyor frame 1. The bottom surfaces of the two long support rods are respectively provided with guide rails 511, and the top surfaces of the first horizontal pusher plate 52 and the second horizontal pusher plate 53 are respectively provided with first sliders 521. Through the one-to-one sliding engagement of the two first sliders 521 and the two guide rails 511, stable and precise sliding guidance is provided for the first horizontal pusher plate 52 and the second horizontal pusher plate 53, which helps to accelerate the pace of the cardboard arrangement process and improve production efficiency.

[0055] Preferably, pulley 541 is a synchronous pulley, transmission belt 542 is a synchronous belt, and first push plate 52 and second push plate 53 are respectively connected to the corresponding synchronous belts through connector 55. Connector 55 includes lower clamping block 551 and upper clamping block 552. Lower clamping block 551 is connected to the top wall of first push plate 52 / second push plate 53, and the top wall of lower clamping block 551 is provided with a receiving groove for synchronous belt to pass through. Upper clamping block 552 is connected above lower clamping block 551, and the bottom wall of upper clamping block 552 is provided with a toothed structure that meshes with synchronous belt.

[0056] The synchronous belt and the synchronous pulley are driven by tooth meshing. This transmission method has an accurate transmission ratio, which can ensure that the first horizontal push plate 52 and the second horizontal push plate 53 move precisely according to the set speed and displacement, so that the cardboard can be accurately arranged laterally according to the design requirements, effectively improving the positioning accuracy in the arrangement process.

[0057] The receiving groove of the lower clamping block 551 provides a stable placement space for the timing belt, and the toothed structure on the bottom wall of the upper clamping block 552 further strengthens the connection between the connector 55 and the timing belt, ensuring that there will be no relative slippage or separation between the timing belt and the push plate during the lateral push movement, so that the power can be reliably transmitted from the timing belt to the push plate, ensuring the continuity and stability of the lateral push operation.

[0058] In some embodiments, the first baffle 3 / second baffle 4 and the conveyor frame 1 are connected by a method such as Figure 4 The structure shown. See also Figure 4 The first baffle 3 and the second baffle 4 are respectively connected to the conveying frame 1 through the lifting cylinder 6. The two ends of the first baffle 3 / second baffle 4 are respectively connected to the vertically extending slide rails 31. The two inner side walls of the conveying frame 1 are respectively provided with second sliders 11 that correspond to and slide in cooperation with the slide rails 31.

[0059] Specifically, the fixed end of the lifting cylinder 6 is connected to the lower part of the conveyor frame 1, and the driving end of the lifting cylinder 6 is connected to the side wall of the first baffle 3 / the second baffle 4. The first baffle 3 / the second baffle 4 are moved up and down by the extension and retraction movement of the lifting cylinder 6, thereby controlling the conveying rhythm of the cardboard.

[0060] By setting the slide rail 31 at both ends of the first baffle 3 / second baffle 4 and setting the second slider 11 on the conveyor frame 1, it can provide a stable and reliable guide for the lifting and lowering movement of the first baffle 3 / second baffle 4, and also allow the slide rail 31 to be retracted into the conveyor frame 1 synchronously after the first baffle 3 / second baffle 4 descends, ensuring the smooth passage of the cardboard.

[0061] As a modified embodiment of the aforementioned cardboard sorting mechanism, see [link to relevant documentation]. Figure 1 and Figure 3 The cardboard sorting mechanism also includes a guide assembly 7 located in front of the first baffle 3. The guide assembly 7 includes two guide plates 71 disposed opposite to each other above the conveyor frame 1. The guide plates 71 have an outward expansion 711 on the side facing the direction of the cardboard.

[0062] When the cardboard is conveyed from the packaging process, it may shift or tilt due to the long transport distance. To ensure that the cardboard can be gathered in the front of the first baffle 3 at a set position and achieve a neat longitudinal arrangement, in this embodiment, two guide plates 71 are provided in front of the first baffle 3. The cardboard is guided into the channel between the two guide plates 71 by the outward expansion 711 of the guide plates 71, thereby calibrating the position of the cardboard and making it neatly gathered in front of the first baffle 3. After the first baffle 3 is lowered, it can move towards the transverse push assembly 5 in an accurate position, which provides a guarantee for the subsequent transverse arrangement.

[0063] The guide assembly 7 can guide and sort the cardboard in advance, so that the cardboard can reach the working position of the first baffle 3 and the horizontal push assembly 5 in an orderly manner, saving the time of positioning and sorting the cardboard, improving the overall cardboard sorting efficiency, and ensuring the effect of cardboard arrangement.

[0064] In addition, the outward expansion section 711 can accommodate paperboards of different specifications. For paperboards of different widths, the outward expansion section 711 can play a preliminary adjustment role and guide them into the correct channel between the guide plates 71, thereby improving the versatility of the guide assembly.

[0065] For example, several guide wheels 72 are rotatably connected to the adjacent sidewalls of the two guide plates 71. The main shaft of the guide wheel 72 extends in the vertical direction, and the several guide wheels 72 are arranged at intervals along the direction of the guide plate 71.

[0066] The guide wheel 72 significantly reduces the frictional resistance between the cardboard and the guide plate 71, which not only allows the cardboard to move more smoothly between the guide plates 71, but also reduces problems such as cardboard surface wear, scratches or edge curling caused by friction, thus improving the conveying quality of the cardboard.

[0067] In some embodiments, the guide assembly 7 described above may adopt the following... Figure 1 and Figure 3The structure shown. See also Figure 1 and Figure 3 The guide assembly 7 also includes two sliding rods 712 and two support seats 73. The two sliding rods 712 are slidably connected to both sides of the conveyor frame 1, and the inner ends of the two sliding rods 712 are connected to the outer side wall of the guide plate 71 respectively. The two support seats 73 are located on both sides of the conveyor frame 1. A locking member 74 is connected to the support seat 73. The locking member 74 is slidably engaged with the sliding rods 712 and is used to lock the corresponding sliding rods 712.

[0068] The sliding connection between the sliding rod 712 and the conveyor frame 1 allows the guide plate 71 to move laterally along the conveyor frame 1, thereby adjusting the distance between the two guide plates 71. In practical applications, the sliding rod 712 can be easily pushed to slide according to the actual size of the cardboard, the conveying path, and other requirements, to adjust the width and position of the guide channel formed by the two guide plates 71. This ensures that the cardboard can be accurately guided to the first baffle 3 and the transverse push assembly 5 according to the set orientation, improving the flexibility and adaptability of the device.

[0069] Based on this, by setting a support base 73 and a locking member 74 on the outside of the conveyor frame 1, on the one hand, another sliding support is provided for the sliding rod 712, which increases the stability of the guide plate 71 during the sliding adjustment process. On the other hand, the position of the sliding rod 712 can be locked by the locking member 74, thereby ensuring the stability of the guide plate 71 in the set position.

[0070] Specifically, the locking element 74 can adopt the structure of the locking block and locking handle in the prior art, as long as it can achieve the function of locking the sliding rod 712, and there is no limitation here.

[0071] Furthermore, the bottom surface of the guide plate 71 is provided with a groove that slides with the roller 2 on the conveyor frame 1, which further increases the stability of the guide plate 71, while not hindering the rolling of the roller 2 and the conveying effect on the cardboard.

[0072] In some embodiments, the second baffle 4 is adopted as follows: Figure 1 and Figure 4 The structure shown. See also Figure 1 and Figure 4 The second baffle 4 is connected to the rear end of the conveyor frame 1. A transition roller 41 is rotatably connected to the rear side wall of the second baffle 4. The transition roller 41 extends perpendicular to the running direction of the cardboard and protrudes from the upper edge of the second baffle 4.

[0073] In this embodiment, the cardboard arrangement process is completed before the second baffle 4. Therefore, the second baffle 4 can be positioned at the rear end of the conveyor frame 1, ensuring the smooth completion of the cardboard arrangement process while also facilitating its installation and maintenance. When the second baffle 4 descends, the transition roller 41, rotatably connected to the rear side wall of the second baffle 4, is aligned with the roller 2 on the conveyor frame 1, allowing the conveyor frame 1 to connect smoothly with the conveying device of the next process. This prevents jamming at the connection point during cardboard conveying, ensuring the continuity and smoothness of the cardboard conveying process and improving conveying efficiency.

[0074] Based on the same inventive concept, this application also provides a packing and palletizing machine, including the aforementioned cardboard sorting mechanism, a packing mechanism 8 located in front of the cardboard sorting mechanism, and a palletizing mechanism 9 located behind the cardboard sorting mechanism.

[0075] This embodiment provides a packing and palletizing machine. Compared with the prior art, the packing mechanism 8 packs the processed cardboard with strapping and conveys it to the conveyor frame 1 of the cardboard sorting mechanism. The first baffle 3 intercepts the cardboard to achieve longitudinal arrangement. When the longitudinally arranged cardboard is conveyed to the second baffle 4, while the second baffle 4 intercepts the cardboard, the first push plate 52 and the second push plate 53 in the cross push assembly 5 cooperate to achieve transverse arrangement of the cardboard, thereby realizing diversified arrangement of each layer of cardboard. Then, the conveyor frame 1 conveys the arranged cardboard layers to the palletizing mechanism 9, and the palletizing mechanism 9 stacks multiple layers of cardboard to form a stack that meets the customer's needs, thus improving work efficiency.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
