Description

Technical Field

[0001] The utility model relates to the field of logistics equipment, in particular to an AGV trolley used for plate roller turnover and a plate roller conveying system. Background Art

[0002] At present, in the plate-making workshop, the semi-finished products between each process need to be checked by employees from the computer production information management system (MES) account book to see which semi-finished products are needed for the next process, and use the material pulling car to transport the required semi-finished products to the next process. Process: dynamic balancing → steel roller grinding → copper plating → copper roller grinding → electronic engraving → chrome plating.

[0003] Chinese patent application CN202120707554.0 discloses an AGV (Automated Guided Vehicle) trolley turnover structure dedicated to plate roller transportation, and proposes the use of a Y-shaped bracket to support the plate roller, and the use of left and right support rods to form an M-shaped storage rack. Although this solution can better support the plate roller and effectively reduce the damage to the plate roller during the plate roller transportation process, it is more suitable for protecting the safe transportation of finished plate rollers. Only a single plate roller can be transported at a time. For semi-finished plate rollers that need to be quickly circulated in the platemaking workshop, it lacks transportation efficiency.

[0004] Therefore, it is necessary to develop a turnover AGV trolley suitable for the rapid circulation of semi-finished plate rollers in the workshop. Utility Model Content

[0024] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0025] Example 1

[0026] The utility model provides a turnover AGV trolley for improving the circulation rate of semi-finished plate rollers in a production workshop, such as Figure 1 As shown, the AVG trolley includes: a trolley body 1 and a plate roller frame 2 arranged and installed on the top of the trolley body 1.

[0027] Among them, a rotating mechanism 3 is arranged on the top of the trolley body 1, and a buckle 4 for fixing the plate roller frame 2 is arranged on the rotating mechanism 3. The plate roller frame 2 is fixed on the rotating mechanism 3 by the buckle 4. During the loading and unloading process, the plate roller frame 2 can be driven by the rotating mechanism 3 to adjust its position, so as to facilitate the loading and unloading of the plate roller at each workstation.

[0028] like Figure 2 As shown, four rows of oblique support rods 21 are symmetrically arranged on both sides of the plate roller frame 2, and there is an acute angle between the oblique support rods 21 and the plate roller frame 2, forming four positions respectively, and each position is correspondingly equipped with a sensor to detect the empty or full state of the position. Specifically, each position is provided with a stress sensor on the central oblique support rod 21, and when the position is loaded with materials, the stress sensor will send a signal. The AGV is also equipped with a plurality of indicator lights corresponding to the positions. The AGV is equipped with a visual screen 5, which can display the version number corresponding to each product.

[0029] Through the arrangement of the plate roller frame 2, the AGV trolley proposed by the utility model can meet the requirement of taking 4 products from point A at a time and sending them to stations 1\2\3\4 respectively; the AGV trolley can accept the next one or more tasks during the normal transportation process.

[0030] Each bin on the plate roller rack 2 of the trolley is equipped with an indicator light, which can be used to remind workers which bin needs to load and unload materials. The screen 5 on the trolley will display which plate corresponds to each bin, and highlight it when it reaches the end, so that workers can recognize the plate number and serial number of the current unloading or loading at a glance.

[0031] Example 2

[0032] As another implementation of the utility model, this embodiment also provides a plate roller conveying system using the AGV trolley described in the above embodiment. The system utilizes the existing MES and AGV scheduling system, including one or more AGV trolleys as described in the above embodiment, and MES operation terminals are respectively set up at each process station. The overall transportation adopts a pull-type production mode, and the next process call is the starting point of the task. The specific principle and working process are as follows:

[0033] 1. The AGV is on standby at the standby point.

[0034] 2. The MES operation terminal at the steel roller grinding station gives a material call signal, and the MES sends a material unloading signal to the scheduling system. The scheduling system generates a production task and assigns the standby AGV car to run to the dynamic balancing station for loading. After that, the AGV car transports the semi-finished plate roller material to the steel roller grinding station for unloading.

[0035] 3. The MES operation terminal at the electric engraving station gives a material call signal, and the MES system sends a material unloading signal to the scheduling system. The scheduling system generates a production task, assigns the standby AGV car to run to the copper roller grinding station for loading, and then transports it to the electric engraving station for unloading to complete the task.

[0036] 4. Transportation process: The overall transportation is in a pull-type production mode. The demand station issues a demand → MES accepts the task → notifies the supply station and the AGV dispatching system → the dispatching system dispatches the task to the appropriate AGV to pick up the material at the supply station → the AGV picks up the material and transports it to the demand station and feeds back the information to the dispatching system → the dispatching system feeds back the information to the MES → the task is completed and the next task is executed.

[0037] Scenario 1: MES sends an instruction from point A to point B to the AGV dispatching system. After receiving the command, the AGV dispatching system allocates the trolley and storage space, and returns it to the MES (trolley, storage space and other information). The AGV trolley will first go to point A to load the plate, and then go to point B to unload the plate.

[0038] Scenario 2: Three semi-finished products are completed at one time in one process, but only one has a clear destination. The three semi-finished products are loaded on the cart at the same time. MES sends the parameters of the semi-finished version with clear start and end (version number, serial number, starting point, and end point) to the AGV scheduling system, and at the same time sends the parameters of the other two versions with unclear end points (version number, serial number, starting point, and end point are empty values). After receiving the command, the AGV scheduling system allocates the AGV cart and storage position, and returns it to MES. MES will focus on recording the other two versions. After the cart with a clear destination arrives at the location to unload the version, the other two versions remain in the cart's storage position. The cart can continue to receive other handling instructions from MES at the same time. When MES clearly determines the end point of the version left in the storage position, it will send parameters to the AGV scheduling system again (version number, serial number, starting point is empty value, end point), and the AGV cart completes the instruction according to the scheduling.

[0039] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
