Description

Technical Field

[0001] The present application belongs to the technical field of logistics packaging lines, and more specifically, to a logistics conveying platform. Background Art

[0002] In existing carton packaging lines, during the transportation of cartons, the placement of the packaged items or external collisions may cause the cartons to shift in position, affecting the subsequent sealing operations of the cartons. To address the above problems, the Chinese utility model patent with publication number CN218520506U discloses an integrated logistics packaging line, which is provided with a first adjustment component and a second adjustment component on the conveying table of the cartons. The first adjustment component has two sets of telescopic cylinders arranged on both sides of the conveying table. The telescopic cylinders clamp the materials in the cartons through push plates and straighten the tilted cartons. The second adjustment component corrects the position of the cartons through two sets of rotating shafts.

[0003] However, in actual operation, the above solution has certain defects. Specifically, if the deflection angle of the packaging box is close to Figure 1 At a large angle of around 45 degrees, the box is directly subjected to diagonal pressure in the first adjustment assembly, preventing it from being straightened and causing the corners to be squeezed and deformed. The second adjustment assembly is also unable to straighten the box at angles close to 45 degrees, affecting subsequent sealing operations. Summary of the Invention

[0004] In order to solve the deficiencies of the existing technology, the utility model provides a logistics conveying platform, which can straighten packaging boxes with a small angle deviation, as well as packaging boxes with a large angle deviation close to 45 degrees, to avoid the packaging boxes being squeezed in the diagonal direction.

[0005] To achieve the above-mentioned objectives, the technical solution of the present application provides a logistics conveyor platform, comprising a roller conveyor platform and a control box, wherein an infrared sensor is provided at the feed end of the roller conveyor platform, and a pushing assembly is installed on the side of the top of the roller conveyor platform, wherein the pushing assembly comprises a telescopic cylinder installed on the roller conveyor platform, the telescopic cylinder extending in a transmission direction perpendicular to the roller conveyor platform, and a push plate is provided at the telescopic end of the telescopic cylinder, and both the infrared sensor and the telescopic cylinder are connected to the control box;

[0006] The roller conveyor table is also equipped with a straightening assembly located on the opposite side of the pushing assembly. The straightening assembly includes a support frame installed on the roller conveyor table, and the support frame is equipped with vertical adjustment rollers arranged along the transmission direction of the roller conveyor table. The vertical adjustment rollers are arranged opposite to the push plate. The support frame is equipped with a drive motor that is transmission-connected to the vertical adjustment rollers, and the outer side wall of the vertical adjustment rollers is provided with vertical straightening grooves.

[0007] When a package box with a skew angle close to 45 degrees runs between the push plate and the vertical adjustment roller, the corner of the package box will be inserted into the vertical alignment groove or between the two vertical adjustment rollers. The package box can be rotated to a certain angle under the toggle of the vertical alignment groove, and then returned to the center through the squeezing effect of the push plate and the vertical adjustment roller, avoiding the situation where a package box with a skew angle of about 45 degrees cannot be returned to the center due to direct squeezing in the diagonal direction.

[0008] Optionally, the vertical alignment groove is in the shape of a triangular notch, having a first sidewall facing the rotational direction of the vertical adjustment roller and a second sidewall facing away from the rotational direction of the vertical adjustment roller. The first sidewall is convexly curved, and the second sidewall is concavely curved. Both the first and second sidewalls smoothly transition into the outer circumference of the vertical adjustment roller. The convexly curved first sidewall, which smoothly transitions into the outer circumference of the vertical adjustment roller, can consistently abut against the packaging box, allowing the packaging box to be aligned at a certain angle without scratching the packaging box surface. The concavely curved second sidewall can somewhat avoid corners of the packaging box, preventing damage to the corners.

[0009] Optionally, each vertical adjustment roller is provided with a plurality of vertical alignment grooves evenly distributed around the roller. When a corner of a box contacts the vertical adjustment roller, the vertical alignment grooves may not yet be aligned, causing friction between the corner and the outer surface of the roller. The plurality of vertical alignment grooves can reduce the friction time between the corner and the outer surface of the roller, allowing the corner to enter the vertical alignment grooves as quickly as possible, thus preventing damage to the corner.

[0010] Optionally, the push assembly further includes a first vertical roller arranged on the push plate, aligned along the transport direction of the roller conveyor deck, and positioned opposite a vertical adjustment roller. After the box is aligned, the linear velocity of the vertical adjustment roller exceeds the transport speed of the box. If the push plate retracts at this point, the vertical adjustment roller may cause the box to slightly tilt, necessitating that the push plate maintain contact with the box. The first vertical roller converts sliding friction between the push plate and the box into rolling friction, thereby reducing friction between the two.

[0011] Optionally, the straightening assembly further includes a second vertical roller, positioned sequentially on the side of the vertical adjustment rollers away from the feed end of the roller conveyor table, and positioned opposite the first vertical rollers. After being straightened, the package box can continue to move between the first and second vertical rollers, completely free of contact with the actively rotating vertical adjustment rollers before the package box is removed from the pushing and straightening assemblies, completely preventing the vertical adjustment rollers from deflecting the package box again.

[0012] Optionally, the push assembly further comprises a mounting plate mounted on the roller conveyor table, the telescopic cylinder being mounted on the mounting plate, and the push plate being provided with a guide rail that slides through the mounting plate. The guide rail can prevent the mounting plate from deflecting and ensure the stability of the telescopic position.

[0013] Optionally, a portal frame is provided at the feed end of the roller conveyor table, the portal frame having a top crossbeam, and an infrared sensor is mounted on the underside of the top crossbeam. When a package box passes through the inside of the portal frame, the infrared sensor detects the package box passing through, and activates the telescopic cylinder on the push assembly through the control box.

[0014] The technical solution of this application has the following advantages over the prior art:

[0015] When a package box with a smaller skew angle runs between the push plate and the vertical adjustment roller, the telescopic cylinder drives the push plate to move, and the package box returns to the correct position under the squeezing action of the push plate and the vertical adjustment roller. When a package box with a skew angle close to 45 degrees runs between the push plate and the vertical adjustment roller, the corner of the package box will be inserted into the vertical alignment groove or between the two vertical adjustment rollers. Under the action of the vertical adjustment roller, the package box rotates a certain angle and then returns to the correct position through the squeezing action of the push plate and the vertical adjustment roller. Therefore, the technical solution of this application will not cause a large angle package box of about 45 degrees to be squeezed in the diagonal direction and unable to return to the correct position, ensuring that all skewed packages can be straightened.

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0023] Example:

[0024] This embodiment provides a logistics conveying platform based on Figure 1 and Figure 2 As shown, it includes a roller conveyor table 1 and a control box 2. The roller conveyor table 1 is used to convey packaging boxes 100. An infrared sensor 3 is provided at the feed end of the roller conveyor table 1, and a pushing component 4 is installed on the top side of the roller conveyor table 1. The pushing component 4 includes a telescopic cylinder 401 installed on the roller conveyor table 1. The telescopic cylinder 401 extends along a transmission direction perpendicular to the roller conveyor table 1. A push plate 402 is provided at the telescopic end of the telescopic cylinder 401. The infrared sensor 3 and the telescopic cylinder 401 are both connected to the control box 2. The infrared sensor 3 is used to sense the passage of the packaging box 100. When a packaging box 100 passes through the feed end of the roller conveyor table 1, the infrared sensor 3 controls the telescopic cylinder 401 pneumatically through the control box 2, driving the push plate 402 to push the packaging box 100 from the side.

[0025] Based on the above structure, Figures 1 to 4As shown, the roller conveyor deck 1 is also equipped with a straightening assembly 5 located opposite the push assembly 4. The straightening assembly 5 is used to cooperate with the push assembly 4 to straighten a tilted package 100. Specifically, the straightening assembly 5 includes a support frame 501 mounted on the roller conveyor deck 1. The support frame 501 is mounted with vertical adjustment rollers 502 arranged along the conveying direction of the roller conveyor deck 1. The vertical adjustment rollers 502 are positioned opposite the push plate 402. A drive motor 503 is mounted on the support frame 501 and is transmission-connected to the vertical adjustment rollers 502. The drive motor 503 drives the vertical adjustment rollers 502 to rotate. In this embodiment, each vertical adjustment roller 502 is equipped with a drive motor 503. Of course, only one drive motor 503 can be provided, which drives all vertical adjustment rollers 502 via gears or other transmission methods. Those skilled in the art will appreciate the appropriate design. The outer wall of the vertical adjustment roller 502 is defined with a vertical straightening groove 504.

[0026] During operation, the linear velocity of the vertical adjustment roller 502 toward the push plate 402 is aligned with the conveying direction of the roller conveyor deck 1, and the surface linear velocity of the vertical adjustment roller 502 is greater than the conveying speed of the roller conveyor deck 1. When a box 100 contacts the vertical adjustment roller 502, it is subjected to a force in the direction of operation. When a box 100 with a small skew angle passes between the push plate 402 and the vertical adjustment roller 502, the telescopic cylinder 401 drives the push plate 402, and the compression between the push plate 402 and the outer surface of the vertical adjustment roller 502 allows the box 100 to return to its normal position. When a box 100 with a skew angle close to 45 degrees passes between the push plate 402 and the vertical adjustment roller 502, two situations occur.

[0027] Case 1: Based on Figure 3 As shown, the corner of the packaging box 100 is inserted into the vertical alignment groove 504. Since the surface linear velocity of the vertical adjustment roller 502 is greater than the transmission speed of the roller conveyor platform 1, the packaging box 100 rotates a certain angle under the action of the vertical alignment groove 504. Then, the packaging box 100 can be straightened by the squeezing action of the push plate 402 and the vertical adjustment roller 502.

[0028] Case 2: Based on Figure 4 As shown, the corner of the packaging box 100 is inserted between the two vertical adjustment rollers 502. Driven by the friction of the two vertical adjustment rollers 502, the corner of the packaging box 100 will enter the bottom vertical adjustment roller 502 ( Figure 4 The packaging box 100 is placed in the vertical alignment groove 504 (in the direction shown), and rotated a certain angle under the toggle of the vertical alignment groove 504, and then the packaging box 100 can be corrected by the squeezing action of the push plate 402 and the vertical adjustment roller 502.

[0029] It can be seen that no matter what the skew angle of the packaging box 100 is, it can be straightened through the straightening effect of the push plate 402, the actively rolling vertical adjustment roller 502 and the vertical straightening groove 504, completely avoiding the situation where the packaging box 100 with a skew of nearly 45 degrees is directly squeezed in the diagonal direction and cannot be straightened.

[0030] Preferably, based on Figure 3 and Figure 4 As shown, the vertical alignment groove 504 is in the shape of a triangular notch. The vertical alignment groove 504 has a first side wall 505 facing the direction of rotation of the vertical adjustment roller 502 and a second side wall 506 facing away from the direction of rotation of the vertical adjustment roller 502. The first side wall 505 faces the direction of rotation of the vertical adjustment roller 502, which means that the first side wall 505 is oriented in the same direction as its linear velocity; the second side wall 506 faces away from the direction of rotation of the vertical adjustment roller 502, which means that the second side wall 506 is oriented in the opposite direction of its linear velocity. The first side wall 505 is convex in shape, and the second side wall 506 is concave in shape. Both the first side wall 505 and the second side wall 506 smoothly transition to the outer circumferential surface of the vertical adjustment roller 502. After the corner of the packaging box 100 enters the adjustment groove, the first side wall 505 abuts against the side wall of the packaging box 100 to drive the packaging box 100 to rotate. The first sidewall 505, with its convex arc shape and smooth transition to the outer surface of the vertical adjustment roller 502, can consistently abut against the packaging box 100, allowing the packaging box 100 to return to a certain angle without scratching the surface of the packaging box 100. The second sidewall 506, with its concave arc shape, can somewhat avoid corners of the packaging box 100, preventing damage. The convex arc shape of the first sidewall 505 and the concave arc shape of the second sidewall 506 effectively reduce the damage rate of the packaging box 100.

[0031] Further, based on Figure 3 and Figure 4 As shown, each vertical adjustment roller 502 is provided with a plurality of vertical alignment grooves 504. "Several" means at least two, such as three or four. The plurality of vertical alignment grooves 504 are evenly distributed around the vertical adjustment roller 502. When the corners of the packaging box 100 contact the vertical adjustment roller 502, the vertical alignment grooves 504 may not yet be aligned, resulting in friction between the corners of the packaging box 100 and the outer circumferential surface of the vertical adjustment roller 502. The plurality of vertical alignment grooves 504 can reduce the friction time between the corners of the packaging box 100 and the outer circumferential surface of the vertical adjustment roller 502, allowing the corners of the packaging box 100 to enter the vertical alignment grooves 504 as soon as possible, thus preventing damage to the corners of the packaging box 100.

[0032] Further, based on Figure 2As shown, the pushing assembly 4 further includes a first vertical roller 403 arranged on the push plate 402. The first vertical roller 403 is arranged along the transport direction of the roller conveyor deck 1 and is disposed opposite the vertical adjustment roller 502. After the packaging box 100 is aligned, since the linear velocity of the vertical adjustment roller 502 is greater than the transport speed of the packaging box 100, if the push plate 402 is retracted, the vertical adjustment roller 502 may cause the packaging box 100 to slightly deflect. Therefore, the push plate 402 must always abut the packaging box 100. The first vertical roller 403 converts the sliding friction between the push plate 402 and the packaging box 100 into rolling friction, thereby avoiding large-scale sliding friction between the push plate 402 and the packaging box 100 and preventing the packaging box 100 from stagnating.

[0033] Preferably, based on Figure 2 As shown, the straightening assembly 5 is further equipped with a second vertical roller 507, which is arranged sequentially on the side of the vertical adjustment roller 502 away from the feed end of the roller conveyor deck 1. The second vertical roller 507 is positioned opposite the first vertical roller 403. After being straightened, the packaging box 100 can continue to move and be restrained between the first vertical roller 403 and the second vertical roller 507. Before the packaging box 100 is removed from between the pushing assembly 4 and the straightening assembly 5, it is completely free of contact with the actively rotating vertical adjustment roller 502, completely preventing the vertical adjustment roller 502 from deflecting the packaging box 100 again.

[0034] In this embodiment, based on Figure 1 and Figure 2 As shown, the push assembly 4 also includes a mounting plate 404 mounted on the roller conveyor deck 1, a telescopic cylinder 401 mounted on the mounting plate 404, and a push plate 402 provided with a guide rail 405 that slides through the mounting plate 404. The guide rail 405 prevents the mounting plate 404 from deflecting, ensuring the stability of the telescopic position. Furthermore, the feed end of the roller conveyor deck 1 is provided with a portal frame 6 having a top crossbeam 7, and an infrared sensor 3 is mounted on the bottom side of the top crossbeam 7. When a package box 100 passes through the inside of the portal frame 6, the infrared sensor 3 detects the passage of the package box 100 and activates the telescopic cylinder 401 of the push assembly 4 through the control box 2.

[0035] The method of using the logistics conveyor shown in this embodiment is as follows:

[0036] The drive motor 503 rotates the vertical adjustment rollers 502. The box 100 passes through the door frame 6 and onto the roller conveyor table 1. After the infrared sensor 3 detects the box 100's passage, the control box 2 activates the telescopic cylinder 401, which drives the push plate 402 and pushes the box 100 against the vertical adjustment roller 502 via the first vertical roller 403. Boxes 100 with a smaller deflection angle are straightened by the squeeze of the push plate 402 and the vertical adjustment roller 502. When a box 100 with a deflection angle close to 45 degrees passes between the push plate 402 and the vertical adjustment roller 502, the corner of the box 100 is inserted into the vertical alignment groove 504 or between the two vertical adjustment rollers 502. The vertical alignment groove 504 allows the box 100 to rotate a certain angle, and then the squeeze of the push plate 402 and the vertical adjustment roller 502 returns the box 100 to its original position. The returned box 100 continues to be conveyed between the first vertical roller 403 and the vertical adjustment roller 502, and then is conveyed between the first vertical roller 403 and the second vertical roller 507, where it is finally removed from between the pushing assembly 4 and the straightening assembly 5. After the box 100 is removed, the telescopic cylinder 401 drives the push plate 402 away from the straightening assembly 5 and returns to its original position, ready for the next box 100 to enter.

[0037] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
