Description

Technical Field

[0001] The utility model relates to the technical field of motor vehicle license plate endorsement, in particular to an automatic buffering device for motor vehicle license plate endorsement. Background Art

[0002] When the motor vehicle license plate is being signed, the speed of signing is slower than the feeding speed of the motor vehicle license plate due to the fast feeding speed. In order to avoid the motor vehicle license plate piling up on the conveyor belt, it is necessary to provide an automatic caching device for the motor vehicle license plate signing, which is used to cache the excess motor vehicle license plate, thereby ensuring work efficiency.

[0003] There are many cache devices in the prior art, for example, an automatic sheet material cache device with publication number CN215363623U, which includes a cache bracket, a baffle, a storage component and a lifting component; wherein the cache bracket is vertically arranged above the transmission mechanism, and the middle part of the cache bracket is a through structure so that the transmission mechanism can drive the sheet material to pass through; the baffle is a rectangular block structure, and the baffle includes two pieces, and the two baffles are arranged on both sides of the bracket; the storage component is slidably arranged on the cache bracket along the vertical direction, and at least two storage layers are evenly spaced in the storage component along the vertical direction: the lifting component is arranged on the cache bracket, and the output end of the lifting component is connected to the storage component, and drives the storage component to move up and down in the vertical direction through the transmission mechanism. Its advantage is that each layer of storage space on the storage component can successively receive the sheet material on the transmission mechanism, and the lifting movement of the multi-layer structure cooperates with the transmission mechanism to realize the automatic sliding of the cover plate into the transfer cache after detection. The disadvantage is that it is inconvenient to take out the cached items, and it cannot be automatically stopped or started, and the work efficiency is not high.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

The present utility model has a simple structure and is easy to use. The present utility model can automatically store and lift the license plate so that the top of the license plate is maintained at the discharge port, which is convenient for the robot to take and place, thereby improving work efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an automatic caching device for motor vehicle license plate signing, including a silo and a lifting system, a manipulator is provided on one side of the silo, a driving member is provided at the bottom of the silo, the output shaft of the driving member is fixedly connected to a screw rod, notches are provided on both sides of the screw rod, a slide rail is provided on one side of each notch, a threaded sleeve is provided on the screw rod, both sides of the threaded sleeve are slidably connected to the slide rail, a material storage plate is fixedly connected to the threaded sleeve through the notch, a cylinder is provided on the top of the silo, a blocking rod is provided on the cylinder, and the blocking rod is slidably connected to both sides of the silo feed port.

[0007] According to the automatic caching device for signing motor vehicle license plates of the utility model, both sides of the material storage plate are provided with limiting plates, and the limiting plates pass through the material storage plate for sliding connection.

[0008] According to the automatic caching device for signing a motor vehicle license plate of the utility model, first limit switches are provided on both sides of the top of the spiral rod, and second limit switches are provided on both sides of the bottom of the spiral rod.

[0011] According to the automatic buffering device for signing motor vehicle license plates of the utility model, the detector at the bottom of the blocking rod is connected to an alarm.

[0012] The purpose of the utility model is to provide an automatic caching device for signing motor vehicle license plates. The program determines whether the manipulator meets the feeding conditions of the signing machine. If so, it directly supplies the signing machine. The program determines that if the signing machine is full, the manipulator automatically collects the material into the silo, and the license plate is placed above the blocking rod. After the material is dropped, the aligning cylinder pushes the material to align it. The third inspector determines whether it is aligning. If it is satisfied, the blocking rod is lowered and the license plate falls into the silo. At this time, the first detector checks that the height of the license plate is higher than the drop position, and the spiral rod drops to the second limit position to reach the drop position. The program determines that if the signing machine is not full and the water belt is not full, the second detector confirms whether the silo has stored license plates. If so, the manipulator picks up the license plate from the feeding height position of the silo and supplies it to the signing machine. The first detector senses that the license plate has been taken away, and the drive member rises to the material taking position. When there is no material in the license plate silo, the feeding is stopped, and the robot is executed first to determine whether the feeding conditions of the signing machine are met. If so, the signing machine is directly supplied. When the silo determines that the silo is full through the limit switch at the screw rod, the program is no longer executed. If the signing machine is full, the robot automatically collects the material into the silo, and the license plate is placed above the blocking rod. After the material is dropped, the calibrating cylinder pushes the material to calibrate it. The third inspector is checked to see if it is calibrated. If it is satisfied, the blocking rod is lowered and the license plate falls into the silo. At this time, the first detector checks that the height of the license plate is higher than the drop position, and the screw rod drops to the second limit to reach the drop position. Only the robot is executed to determine whether the feeding conditions of the signing machine are met. If so, the signing machine is directly supplied. The program determines that if the signing machine is not full and the water belt is not full, the second detector confirms whether the silo has stored license plates. If so, the robot picks up the license plate from the silo feeding height position and supplies it to the signing machine. The first detector senses that the license plate has been taken away, and the drive element rises to the material collection position. When there is no material in the license plate silo, the feeding is stopped, and the robot is given priority to judge by the program whether the feeding conditions of the signing machine are met. If so, it is directly supplied to the signing machine. Only when it is switched to manual mode and materials are stored and retrieved, human intervention is required.

[0021] See also Figure 1 to Figure 4 The utility model provides an automatic caching device for signing a motor vehicle license plate, including a silo 2 and a lifting system. A manipulator 1 is provided on one side of the silo 2. The manipulator 1 is a prior art and will not be described in detail in this specification. A driving member 3 is provided at the bottom of the silo 2. The output shaft of the driving member 3 is fixedly connected to a screw rod 4. Notches 5 are provided on both sides of the screw rod 4. A slide rail 7 is provided on one side of each of the notches 5. A threaded sleeve 6 is provided on the screw rod 4. Both sides of the threaded sleeve 6 are slidably connected to the slide rail 7. The threaded sleeve 6 is fixedly connected with a storage plate 8 through the notch 5. The notch 5 is used for the threaded sleeve 6 to connect the storage plate 8, that is, to drive the storage plate 8 to rise or fall. The slide rail 7 is used to cooperate with the movement of the threaded sleeve 6 and is also used to maintain the balance of the threaded sleeve 6. A cylinder 21 is provided on the top of the silo 2. A blocking rod 23 is provided on the cylinder 21. The blocking rod 23 is slidably connected to both sides of the feeding port 22 of the silo 2.

[0022] See also Figure 1 to Figure 4 In a further embodiment, limit plates 81 are provided on both sides of the material storage plate 8, and the limit plates 81 are slidably connected through the material storage plate 8. On the one hand, the limit plates 81 are used to further maintain the balance of the material storage plate 8. On the other hand, the limit plates 81 limit the license plate from being offset on the material storage plate 8, thereby ensuring that the license plate can be placed exactly at the signing machine when it is taken out by the robot 1 without adjusting the direction of the license plate.

[0023] See also Figure 1 to Figure 4 In a further embodiment, a first limit switch 61 is provided on both sides of the top of the screw rod 4, and a second limit switch 62 is provided on both sides of the bottom of the screw rod 4. When a large number of license plates enter the silo 2, the driving member 3 rotates forward, and the driving member 3 drives the threaded sleeve 6 to descend, and the threaded sleeve 6 drives the storage plate 8 to descend. When the threaded sleeve 6 descends to the second limit switch 62, the second limit switch 62 restricts the driving member 3 from rotating forward, which indicates that the silo 2 is full. The first limit switch 61 is used when the license plates in the silo 2 are taken out. The driving member 3 reverses, and the storage plate 8 rises under the action of the threaded sleeve 6. When the threaded sleeve 6 rises to the first limit switch 61, the driving member 3 stops rotating, that is, all the license plates in the silo 2 are taken out.

[0024] See also Figure 1 to Figure 4 In a further embodiment, an adjusting plate 24 is provided at one end of the feed port 22, and the adjusting plate 24 is connected to the cylinder 21. A third detector 9 is provided on the opposite side of the adjusting plate 24, and the third detector 9 is fixedly connected to the silo 2. The adjusting plate 24 is used to adjust the number plate placed by the regulating robot 1 in the silo 2, and the third detector 9 is used to detect whether the number plate is in place and regulated.

[0025] See also Figure 1 to Figure 4 In a further embodiment, a first detector 10 is provided at the bottom of the blocking rod 23, and a second detector 11 is provided at the bottom of the storage plate 8. The first detector 10 below the blocking rod 23 is used to detect whether the top number plate on the storage plate 8 is below the blocking rod 23. When the manipulator 1 wants to take the number plate, the storage plate 8 lifts the top number plate to the material taking position through the screw rod 4, the driving member 3 and the threaded sleeve 6. The manipulator 1 takes away the first number plate, the cylinder 21 resets, the storage plate 8 is lifted, and the second number plate is still at the top material taking position.

[0026] See also Figure 1 to Figure 4 In a further embodiment, the second detector 11 at the bottom of the blocking rod 23 is connected to an alarm 12. The alarm 12 is used to transmit a signal to the alarm 12 when the number plate on the water belt is full and the second detector 11 does not detect the number plate on the storage plate 8. The alarm 12 prompts the equipment to automatically switch modes.

[0027] See also Figure 1 to Figure 4 In a further embodiment, the driving member 3 is a rotating motor, and the first detector 10, the second detector 11 and the third detector 9 are all prior art, such as infrared detectors, that is, their model structures are all prior art and will not be described in detail in this specification.

[0028] During the implementation of the utility model: the robot 1 is judged by the program whether it meets the feeding conditions of the signing machine. If so, it directly supplies the signing machine. The program judges that if the signing machine is full of materials, the robot 1 automatically collects the materials into the silo 2, and the number plate is placed above the blocking rod 23. After the material is dropped, the calibrating cylinder 21 pushes the material to calibrate it. The third inspector 9 is calibrated. If it is satisfied, the blocking rod 23 is lowered, and the number plate falls into the silo 2. At this time, the first detector 10 checks whether the height of the number plate is higher than the drop position, and the screw rod 4 drops to the second limit switch 62 to reach the drop position. The program judges that if the signing machine is not full and the water belt is not full of materials, the second detector 11 confirms whether the silo has stored the number plate. If so, the robot 1 picks up the number plate from the feeding height position of the silo 2 and supplies it to the signing machine. The first detector 10 senses that the number plate is taken away, and the drive member 3 rises to the material taking position. When there is no material in the license plate silo 2, the feeding is stopped, and the program judgement of the manipulator 1 is given priority to determine whether the feeding conditions of the signing machine are met. If so, the signing machine is directly supplied. When the silo 2 determines that the silo 2 is full of material through the limit switch at the screw rod 4, the program judgment is no longer executed. If the signing machine is full of material, the manipulator 1 automatically collects the material into the silo 2, and the license plate is placed above the blocking rod 23. After the material falls, the aligning cylinder 21 pushes the material to align it. The third inspector 9 is checked to see if it is aligning. If satisfied, the blocking rod 23 is lowered and the license plate falls into the silo 2. At this time, the first detector 10 checks that the height of the license plate is higher than the blanking position, then the screw rod 4 drops to the second limit switch 62 to reach the blanking receiving position, and only the robot 1 is executed by the program to determine whether the feeding conditions of the signing machine are met. If so, it is directly supplied to the signing machine. The program determines that if the signing machine is not full and the water belt is not full, the second detector 11 confirms whether the silo 2 has stored license plates. If so, the robot 1 picks up the license plate from the feeding height position of the silo 2 and supplies it to the signing machine. The first detector 10 senses that the license plate is taken away, and the drive member 3 rises to the material removal position. When there is no material in the license plate silo 2, the feeding is stopped, and the robot 1 is executed by the program to determine whether the feeding conditions of the signing machine are met. If so, it is directly supplied to the signing machine. Manual intervention is only required when switching to manual mode and storing and retrieving materials.

[0029] The utility model provides an automatic caching device for signing motor vehicle license plates. By arranging a robot arm, the license plates can be taken and placed. By arranging a spiral rod, the storage plate can be raised or lowered. By arranging a detector, the top license plate can be always at the material taking position, which is convenient for taking and placing. In summary, the utility model has a simple structure and is easy to use. It can automatically store and lift the license plate, so that the top of the license plate is maintained at the discharge port, which is convenient for the robot arm to take and place, thereby improving work efficiency.
