Description

Technical Field

[0001] This utility model relates to the field of box conveying technology, and in particular to a box alignment and positioning device. Background Technology

[0002] In numerous fields such as logistics warehousing, product processing, and automated assembly, containers serve as the core carriers for material storage and transfer. Their posture regularity during the transport process directly impacts the efficiency and accuracy of subsequent processes. For example, in automated sorting systems, containers must maintain a preset posture to accurately align with barcode scanning devices; in assembly lines, the positioning accuracy of the containers determines the fit of assembled parts; and in warehouse stacking, a regular container posture is a crucial prerequisite for achieving automated stacking and improving warehouse space utilization. Therefore, efficient and accurate container positioning has become a significant technological requirement driving automation upgrades in related industries.

[0003] Existing mechanical devices for positioning boxes are mostly based on structures such as cylinder-driven clamping plates and single-motor-driven single-sided positioning mechanisms. However, some devices use multiple sets of cylinders to independently drive the positioning components. Due to the difference in the pneumatic response speed of the cylinders, the positioning components on both sides are prone to asynchronous movement, causing the box to tilt during the alignment process, or even damaging the box or the positioning device. At the same time, the movement trajectory of the positioning plate in existing mechanical positioning devices is mostly adjusted in a single direction, that is, it can only achieve horizontal clamping and alignment or only vertical lifting and avoidance, making it difficult to take into account the coordinated action of "alignment clamping" and "transfer and avoidance". After the box is aligned, an additional avoidance mechanism is required to enable the box to continue to be transported, resulting in low overall integration of the equipment and large space occupation. To solve the above problems, this application proposes a box alignment and positioning device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a box alignment and positioning device. This device adopts dual servo motor reverse collaborative control, combined with a synchronous pulley, synchronous belt, sprocket, and chain transmission structure to avoid asynchronous movement of the positioning components on both sides, prevent box tilting or damage, and improve alignment stability. The positioning plate can simultaneously achieve relative movement (alignment clamping) and vertical movement (conveyance and avoidance), eliminating the need for an additional avoidance mechanism, thereby improving equipment integration and reducing space occupation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A box-type alignment and positioning device includes two plates arranged symmetrically. A reinforcing beam is fixedly connected to both plates. Two transmission mechanisms are provided between the two plates. Each transmission mechanism includes a servo motor fixedly connected to the front end of the rear plate. The output shaft of the servo motor passes through the plate and is rotatably connected to it.

A box body is provided between the two plates. Multiple transmission rollers are provided at the bottom of the box body. Each transmission roller has a C-shaped seat at both ends. The two ends of each transmission roller are rotatably connected to the side wall of the corresponding C-shaped seat. A second synchronous belt is fitted onto adjacent transmission rollers.

[0006] Preferably, the moving mechanism includes a transmission rod rotatably connected to both plates. Both ends of the transmission rod pass through the plates and are rotatably connected to them. Both ends of the transmission rod are coaxially and fixedly connected to corresponding driven synchronous wheels. Two first sprockets are fixedly connected to the outer wall of the transmission rod. A second sprocket, a third sprocket, and a fourth sprocket are rotatably connected to the opposite ends of the two plates. The first sprocket, the second sprocket, the third sprocket, and the fourth sprocket on the same side are all fitted with chains. The two chains are all fixedly connected to a positioning plate.

[0007] Preferably, the second sprocket, the third sprocket, and the fourth sprocket are all coaxially fixedly connected to a rotating shaft, and the plurality of rotating shafts are rotatably connected to the plate body.

[0008] Preferably, both ends of the positioning plate are fixedly connected to connecting rods, and the two connecting rods are respectively fixedly connected to the side wall of their corresponding chains.

A conveying motor is fixedly connected to the side wall of one of the C-shaped seats, and the output end of the conveying motor is coaxially fixedly connected to one of the transmission rollers.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. This equipment adopts dual servo motor reverse collaborative control, combined with synchronous pulley, synchronous belt, sprocket and chain transmission structure to avoid asynchronous movement of positioning components on both sides, prevent the box from tilting or being damaged, and improve the stability of alignment.

[0012] 2. Replace complex gear sets with synchronous pulleys, synchronous belts, sprockets, and chains to simplify the structure, reduce assembly difficulty, reduce transmission wear, extend service life, and reduce maintenance costs.

[0013] 3. The positioning plate can simultaneously achieve relative movement (alignment clamping) and vertical movement (conveyance and obstacle avoidance), eliminating the need for an additional obstacle avoidance mechanism, thereby improving equipment integration and reducing space occupation.

[0014] 4. This equipment replaces manual operation, is suitable for conveying scenarios, avoids accuracy fluctuations caused by human fatigue, and reduces labor intensity and personnel safety hazards.

[0015] In summary, this equipment adopts dual servo motor reverse collaborative control, combined with a synchronous pulley, synchronous belt, sprocket, and chain transmission structure to avoid asynchronous movement of the positioning components on both sides, prevent the box from tilting or being damaged, and improve the stability of the alignment. The positioning plate can realize relative movement (alignment clamping) and up and down movement (conveyor clearance) simultaneously, without the need for an additional clearance mechanism, thereby improving the integration of the equipment and reducing the space occupied.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4A box alignment and positioning device includes a plate 1, which provides an installation carrier for other components. Two plates 1 are symmetrically arranged, and both plates 1 are fixedly connected to a reinforcing beam 2. The reinforcing beam 2 is fixedly connected to external equipment and enhances the connection strength between the two plates 1, improving the overall structural stability. Two transmission mechanisms are provided between the two plates 1. Each transmission mechanism includes a servo motor 3 fixedly connected to the front end of the rear plate 1. The servo motor 3 provides driving force to the transmission mechanism, and the rotation of its output shaft can drive the movement of subsequent components. The output shaft of 3 passes through the plate 1 and is rotatably connected to it. The end of the output shaft of the servo motor 3 is fixedly connected to the active synchronous wheel 4. The active synchronous wheel 4 rotates synchronously with the output shaft of the servo motor 3 and transmits power through cooperation with the first synchronous belt 5. The back end of the rear plate 1 is rotatably connected to the driven synchronous wheel 6. The outer wall of the active synchronous wheel 4 and the outer wall of the driven synchronous wheel 6 are together fitted with the first synchronous belt 5. The first synchronous belt 5 transmits the rotational motion of the active synchronous wheel 4 to the driven synchronous wheel 6, so that the driven synchronous wheel 6 rotates in coordination with the active synchronous wheel 4. The driven synchronous wheel 6 is provided with a moving mechanism.

[0020] The moving mechanism includes a transmission rod 9 rotatably connected to both plates 1. The transmission rod 9 rotates under the drive of the driven synchronous wheel 6, simultaneously transmitting the rotational motion to components on both sides. Both ends of the transmission rod 9 penetrate the plates 1 and are rotatably connected to them. Each end of the transmission rod 9 is coaxially and fixedly connected to its corresponding driven synchronous wheel 6. Two first sprockets 8 are fixedly connected to the outer wall of the transmission rod 9. The first sprockets 8 rotate synchronously with the transmission rod 9, driving the chain 13 through meshing with it. A second sprocket 10, a third sprocket 11, and a fourth sprocket 12 are rotatably connected to the opposite ends of the two plates 1. Each of the second sprockets 10, third sprocket 11, and fourth sprocket 12 is coaxially and fixedly connected to a rotating shaft. Multiple rotating shafts are rotatably connected to the plates 1. Sprockets 10, 11, and 12 guide and support the chain 13, ensuring it moves along a preset trajectory. On the same side, sprockets 8, 10, 11, and 12 together mount the chain 13. Two chains 13 are fixedly connected to a positioning plate 14. The movement of the chain 13 causes the positioning plate 14 to move synchronously. The positioning plate 14 can be adjusted to correct the position of the housing (the chains 13 around the second sprocket 10 are arranged at right angles; the synchronous rotation of the two second sprockets 10 can move the positioning plate 14 both vertically and horizontally; the upward movement of the positioning plate 14 facilitates the transport of the housing body 7, while the relative movement of the positioning plates 14 on both sides corrects the positioning of the housing body 7). Connecting rods are fixedly connected to both ends of the positioning plate 14. Each connecting rod is fixedly connected to the side wall of its corresponding chain 13, securing the positioning plate 14 to the chain 13 and allowing the positioning plate 14 to change position with the movement of the chain 13.

[0021] A housing body 7 is located between the two plates 1. The housing body 7 is the alignment target of the equipment and will be moved to the alignment position by the conveying rollers 16. Multiple conveying rollers 16 are located at the bottom of the housing body 7, and the positions of the multiple conveying rollers 16 are evenly distributed. The tops of the multiple conveying rollers 16 are arranged to abut against the bottom of the housing body 7, supporting the bottom of the housing body 7. Their rotation can drive the housing body 7 to move along the conveying direction. Each end of the conveying roller 16 is provided with a C-shaped seat 15, which is fixedly connected to external equipment for positioning. The two ends of each conveying roller 16 are rotatably connected to the side wall of the corresponding C-shaped seat 15. The C-shaped seat 15 is the conveying roller. 16 provides rotational support to ensure stable rotation of the drive roller 16. Two adjacent drive rollers 16 are fitted with a second synchronous belt 17. A synchronous pulley is fixedly connected to the outer wall of each drive roller 16. The second synchronous belt 17 is arranged on the outer wall of the two synchronous pulleys. The second synchronous belt 17 transmits the rotational motion of the adjacent drive rollers 16 synchronously through the synchronous pulleys to ensure that the speed of multiple drive rollers 16 is consistent. A conveyor motor is fixedly connected to the side wall of one of the C-shaped seats 15. The output end of the conveyor motor is coaxially fixedly connected to one of the drive rollers 16. The conveyor motor provides power for the rotation of the drive roller 16 and drives all drive rollers 16 to operate in coordination through the second synchronous belt 17.

[0022] In this invention, the arrangement of the conveyor motor and multiple second synchronous belts 17 enables multiple transmission rollers 16 to perform synchronous transmission, thereby conveying the box body 7 until it is conveyed to the bottom of the reinforcing beam 2. At this time, the conveyor motor is turned off, and the box body 7 is stationary. Two servo motors 3 are started and their output shafts rotate in opposite directions. The output shafts of the servo motors 3 drive the active synchronous wheel 4, the first synchronous belt 5, the driven synchronous wheel 6, the transmission rod 9, the first sprocket 8, the second sprocket 10, the third sprocket 11, the fourth sprocket 12 and the chain 13 on both sides to rotate. The two chains 13 rotate in opposite directions, thereby causing the positioning plates 14 on both sides to move relative to each other and move down to abut against the sides of the box body 7, completing the alignment of the box body 7. Finally, the two servo motors 3 reverse direction, causing the positioning plates 14 on both sides to move in opposite directions, thereby releasing the box body 7. The height of the positioning plates 14 is then raised, and the conveyor motor can be started to continue conveying the box body 7.
