Description

Technical Field

[0001] This utility model relates to the field of cargo transportation technology, and in particular to an automatic cargo centering and positioning device. Background Technology

[0002] During the transportation of goods, the conventional method is to use conveyor lines, such as roller conveyors. To ensure the goods are aligned before stacking, a prior art cargo transportation centering and guiding mechanism (publication number CN216104140U) is used. This mechanism places the goods on drive rollers, and a drive device drives the drive rollers to rotate, thereby moving the goods. Multiple centering and guiding units are set up. Each centering and guiding unit includes two centering and guiding groups arranged opposite to each other. Within each centering and guiding group, a motor, threaded rod, sliding block, connecting rod, push plate, fixed rod, and connecting column form a screw assembly. The inner side of the push plates between the two centering and guiding groups within one of the centering and guiding units is defined. The two sides of the two push plates are the outer sides. In actual use, when the goods deviate and come into contact with the pressure sensor on the inner wall of the push plate, the pressure sensor sends information to the microcontroller. The microcontroller controls the motor in the centering and guiding unit where the push plate is located to rotate. The rotation of the motor drives the threaded rod to rotate, which in turn drives the sliding block to move inward, which in turn drives the connecting plate and the push plate to move inward. The movement of the push plate pushes the goods a set distance, so that the goods return to the center position. Then the motor returns to the initial position. In this way, once the goods deviate, whether to the left or the right, the centering and guiding unit can bring the goods back to the center position, ensuring the normal operation of the goods and reducing the use of manpower.

[0003] However, with existing technology, when adjusting the angle of goods placement, the bottom surface of the goods will come into contact with the transmission roller and generate friction. This friction will generate additional resistance, which may cause scratches on the bottom surface of the goods during movement or affect the smoothness of the goods movement. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an automatic cargo centering and positioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic cargo centering and positioning device, comprising a conveyor line, a mounting frame fixedly installed at the bottom edge of the end of the conveyor line, a socket sleeved on the mounting frame, the socket being distributed parallel to the length direction of the conveyor line and sliding along the width direction of the conveyor line, an upwardly extending electric telescopic rod fixedly installed at both ends of the top edge of the socket, and a movable seat fixedly installed at the telescopic ends of the two electric telescopic rods on the socket, a roller rotatably connected between two adjacent transmission rollers inside the conveyor line at the top edge of the movable seat, the roller frame being rotatably connected to the movable seat and having a connecting gear fixedly installed through the rotating part of the movable seat, the connecting gear being located inside the movable seat and an insert rack meshing with the connecting gear being inserted into the top edge of the movable seat.

[0006] Preferably, a pneumatic push rod is installed in the movable seat at the position of each insert rack, the pneumatic push rod is arranged parallel to the insert rack and the telescopic end of the pneumatic push rod is fixedly connected to one end of the corresponding insert rack.

[0007] Preferably, a piston cylinder assembly is fixedly installed on the outside of the movable seat, and an air pipe is installed on the cylinder end face of the piston cylinder assembly. The air pipe passes through several pneumatic push rods of the same movable seat, and a solenoid valve is provided between the air pipe and the air inlet of each pneumatic push rod.

[0008] Preferably, a third electric push rod is also fixedly installed on the outside of the movable seat, which is parallel to the piston cylinder assembly, and the telescopic end of the third electric push rod is fixedly connected to the piston rod of the piston cylinder assembly.

[0009] Preferably, a number of sockets are divided into two groups of equal quantity and respectively arranged on both sides of the mounting frame. A second electric push rod is provided between the sockets and the mounting frame, and the second electric push rod extends and retracts along the width direction of the conveyor line.

[0010] Preferably, rack frames are fixedly installed on both long sides of the conveyor frame, slide blocks are inserted into the rack frames, and a first electric push rod that extends and retracts along the width of the conveyor line is fixedly installed through the slide blocks, with a push block fixedly installed at the telescopic end of the first electric push rod.

[0011] Preferably, one side of the upper surface of the slide is hollowed out and a spur gear is rotatably connected to the hollowed-out part. The spur gear is driven by a motor and meshes with a rack on the rack frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting rollers, the goods are completely separated from the transmission rollers after being lifted by the rollers. When adjusting the angle, the bottom surface of the goods only contacts the roller tires, and the rollers rotate synchronously with the goods. The synchronous rotation of the roller tires converts sliding friction into rolling friction. The force generated by rolling friction is much smaller than that of sliding friction, which effectively avoids scratches, wear and other damage to the bottom surface of the goods caused by friction.

[0013] 2. In this invention, the slide block is connected to the rack and pinion frame via a spur gear, allowing it to slide freely along the length of the conveyor line. Combined with the extension and retraction adjustment of the first electric push rod along the width direction, the range of motion of the push block can cover most of the conveyor line. Whether for small goods or extra-wide and extra-long large goods, the precise point of force application can be found by adjusting the position of the slide block and the extension length of the push block, avoiding ineffective correction due to the size of the goods exceeding the adjustment range.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figures 1-4As shown, an automatic cargo centering and positioning device includes a conveyor line 1. Several drive rollers are installed on the surface of the conveyor line 1 to achieve cargo translation. A mounting frame 8 is fixedly installed at the bottom edge of the end of the conveyor line 1. A socket 10 is fitted onto the mounting frame 8. The length direction of the socket 10 is parallel to the length direction of the conveyor line 1, and the socket 10 slides along the width direction of the conveyor line 1. Two upward-extending electric telescopic rods 9 are fixedly installed at both ends of the top edge of the socket 10, and movable seats 7 are fixedly installed at the telescopic ends of the two electric telescopic rods 9 on the socket 10. The extension of the electric telescopic rods 9 enables the movable seats 7 to rise and fall. Rollers 11 are rotatably connected between adjacent drive rollers inside the conveyor line 1 at the top edge of the movable seat 7. The frame of the roller 11 is rotatably connected to the movable seat 7, and the rotating part passes through the movable seat 7 and is fixedly installed with a connecting gear 17. The connecting gear 17 is located inside the movable seat 7, and an insert rack 18 that meshes with the connecting gear 17 is inserted into the top edge of the movable seat 7. Under normal circumstances, the cargo travels on the conveyor line 1. When the angle of the cargo needs to be adjusted, the angle of the cargo is adjusted according to the cargo centering and positioning device. The width of the object is adjusted by sliding the socket 10 on the mounting bracket 8 to adjust the position of the movable seat 7. The sliding drive of the connecting gear 17, which is connected by the insert rack 18 inside the movable seat 7, rotates the connecting gear 17. The rotation of the connecting gear 17 drives the rollers 11 to rotate at a certain angle, so that the rollers 11 that are about to contact the bottom of the object are arranged in a circular array around a point. The central axis of the roller hubs of the rollers 11 points to the reference origin of the circular array. Then, the movable seat 7 rises under the push of the electric telescopic rod 9 until the surface of the rollers 11 tires is higher than the transmission roller of the conveyor line 1. The rollers 11 tires can then push the object up and away from the conveyor line 1. The object can be rotated by pushing it left and right under the support of several rollers 11 tires to achieve the correct position. During the rotation of the object, the rollers 11 tires rotate synchronously, so there is no frictional resistance between them and the bottom surface of the object. In addition, by adjusting the rollers 11 tires to be perpendicular to the transmission roller on the conveyor line 1, it is also convenient for the object to slide left and right on the conveyor line 1 to adjust its position.

[0019] A pneumatic push rod 19 is installed in the movable base 7 at the position of each insert rack 18. The pneumatic push rod 19 is arranged parallel to the insert rack 18, and the telescopic end of the pneumatic push rod 19 is fixedly connected to one end of the corresponding insert rack 18. The pneumatic push rod 19 can be manually inflated or deflated to move the corresponding insert rack 18, thereby realizing the rotation of the corresponding meshing connecting gear 17.

[0020] A piston cylinder assembly 13 is fixedly installed on the outside of the movable seat 7. An air pipe 15 is installed on the cylinder end face of the piston cylinder assembly 13. The air pipe 15 passes through several pneumatic push rods 19 of the same movable seat 7, and a solenoid valve 16 is provided between the air pipe 15 and the air inlet of each pneumatic push rod 19. A third electric push rod 14 is also fixedly installed on the outside of the movable seat 7, which is parallel to the piston cylinder assembly 13. The telescopic end of the third electric push rod 14 is fixedly connected to the piston rod of the piston cylinder assembly 13. In use, the piston rod moves by telescoping the third electric push rod 14, thereby realizing the intake or release of air from the piston cylinder. The air pipe 15 and the solenoid valve 16 facilitate the operation of the personnel. By opening and closing the solenoid valve 16 at the corresponding position and controlling the opening time, when the piston cylinder part of the piston cylinder assembly 13 is being drawn or released, the air pipe 15 and the correspondingly opened solenoid valve 16 are used to draw or fill the connected pneumatic push rod 19, thereby realizing the retraction or extension of the corresponding connected pneumatic push rod 19.

[0021] Several sockets 10 are divided into two groups according to their quantity and are respectively set on both sides of the mounting frame 8. A second electric push rod 12 is provided between the sockets 10 and the mounting frame 8. The second electric push rod 12 extends and retracts along the width direction of the conveyor line 1. By extending and retracting the second electric push rod 12, the corresponding connected sockets 10 can slide along the surface of the mounting frame 8, thereby adjusting the spacing of the several sockets 10 and thus adjusting the distribution spacing of the movable seat 7.

[0022] On both sides of the long side of the conveyor line 1 frame, rack frames 2 are fixedly installed. Slides 3 are inserted into the rack frames 2. A first electric push rod 5, which extends and retracts along the width of the conveyor line 1, is fixedly installed through the slides 3. A push block 6 is fixedly installed at the telescopic end of the first electric push rod 5. One side of the upper surface of the slide 3 is hollowed out, and a spur gear 4 is rotatably connected to the hollowed-out area. The spur gear 4 is driven by a motor and meshes with the rack on the rack frame 2. Depending on the placement of the goods and the position to be pushed, the spur gear 4 on the corresponding side slide 3 rotates, cooperating with... The meshing connection of the rack on the rack frame 2 enables the slide block 3 to slide and adjust its position on the rack frame 2. Then, the first electric push rod 5 on the slide block 3 extends to move the push block 6. The push block 6 forces the goods to rotate and adjust their direction under the support of the roller 11 tire. After the direction adjustment is completed, the slide block 3 on the other side of the rack frame 2 moves and the push block 6 on the slide block 3 on this side comes into contact with the surface of the goods to ensure that the goods are in the correct position. Then, the moving seat 7 descends to make the goods fall down and re-contact with the transmission roller on the conveyor line 1.

[0023] The method of using this utility model is as follows: Based on the width of the goods, the second electric push rods 12 on both sides of the mounting frame 8 are extended and retracted, causing the socket 10 to slide along the mounting frame 8, thereby adjusting the distribution spacing of the movable seats 7 on both sides to ensure that the movable seats 7 can accurately correspond to the bottom position of the goods. The third electric push rod 14 is activated to drive the piston rod of the piston cylinder assembly 13 to move, causing the piston cylinder to inhale or exhale. By controlling the opening and closing time of the solenoid valve 16 at the corresponding position on the air pipe 15 on the outside of the movable seat 7, the target pneumatic push rod 19 is charged and de-charged. The extension and retraction of the pneumatic push rod 19 causes the insert rack 18 to slide, thereby driving the meshing connecting gear 17 to rotate, causing the rollers 11 on the movable seat 7 to rotate to a preset angle, forming a circular array distribution, with the central axis of the roller hub pointing to the center of the bottom surface of the array goods.

[0024] The electric telescopic rod 9 on the control socket 10 extends, pushing the movable seat 7 to rise until the rollers 11 on the surface of the movable seat 7 are higher than the transmission rollers of the conveyor line 1. The rollers 11 lift the goods, causing them to detach from the transmission rollers. According to the initial placement position of the goods, the spur gear 4 on the slide 3 on the corresponding side rack frame 2 is driven to rotate. The spur gear 4 and the rack frame 2 mesh to move the slide 3 to the target position. The first electric push rod 5 on the slide 3 is extended, and the push block 6 pushes the goods, forcing the goods to rotate and adjust their direction under the support of the rollers 11.

[0025] After the cargo orientation is adjusted, move the slide block 3 on the other side of the rack frame 2 so that the push block 6 on that side fits against the cargo surface to ensure that the cargo remains in a straight position. Control the electric telescopic rod 9 to retract, the moving seat 7 to descend, and the cargo re-engages with the drive roller of the conveyor line 1 to complete the position adjustment and continue conveying.

[0026] The wiring diagrams for the transmission line 1, the first electric push rod 5, the electric telescopic rod 9, the second electric push rod 12, the third electric push rod 14, and the solenoid valve 16 in this utility model are common knowledge in the field. Their working principles are known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring arrangements for the transmission line 1, the first electric push rod 5, the electric telescopic rod 9, the second electric push rod 12, the third electric push rod 14, and the solenoid valve 16 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
