Description

Technical Field

[0001] This utility model relates to the field of coating and printing production equipment technology, and in particular to a paint storage device for a can body sheet coating and printing production line. Background Technology

[0002] In the production process of empty can body raw materials, it is usually necessary to coat and print the raw iron sheet used to make the can body. Currently, the paint used in the coating and printing process is transported in barrels. In order to reduce the frequency of transportation and reduce production costs, several barrels of paint are usually purchased in advance and stacked in a corner of the workshop after arrival. If the paint barrels are not moved for a long time, the paint inside will settle. Therefore, before using the paint, the paint barrels need to be placed in the paint shaking machine and shaken before they can be opened and used. This method takes up too much space for the paint barrels and the paint cannot be opened and used immediately, which affects production efficiency. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a paint storage device for a can body sheet metal coating production line.

[0004] This utility model is implemented using the following method: a paint storage device for a can body sheet metal coating production line, comprising a multi-axis moving mechanism and a three-dimensional storage rack, wherein the multi-axis moving mechanism is opposite to the three-dimensional storage rack, the three-dimensional storage rack is provided with multiple storage stations, each of the storage stations is provided with a rotary drive mechanism, the paint bucket is placed on the rotary drive mechanism, the rotary drive mechanism is used to drive the paint bucket to rotate; a fork-lifting component is installed on the multi-axis moving mechanism, and the storage station is provided with a clearance gap so that the fork-lifting component can pick up and put down the paint bucket.

[0005] Preferably, the rotary drive mechanism includes a driving roller and a driven roller, which are symmetrically arranged on both sides of the storage station, and the distance between the driving roller and the driven roller is less than the diameter of the paint bucket.

[0007] Preferably, each of the storage stations is provided with symmetrical support frames on both sides, and bearing seats are installed on the support frames. The driving roller and the driven roller are rotatably connected to the bearing seats on the corresponding sides, and the distance between the support frames is greater than the distance between the driving roller and the driven roller.

[0008] Preferably, the driven roller is a heating roller.

[0009] Preferably, the fork-taking assembly includes two forks and a fork drive unit, the fork drive unit being mounted on the multi-axis moving mechanism, and the forks being mounted on the fork drive unit.

[0010] Preferably, the distance between the two forks is less than the distance between the driving roller and the driven roller.

[0011] Preferably, the multi-axis moving mechanism is provided with a support frame, the support frame is U-shaped, the fork assembly is installed on the bottom surface inside the support frame, the multi-axis moving mechanism can drive the planar displacement of the support frame, and the distance between the two arms of the support frame is greater than the diameter of the paint bucket.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a paint storage device for a can body sheet metal coating production line. Compared with the prior art, this utility model has at least the following technical effects: 1. The structure of the three-dimensional storage rack with multiple storage stations equipped with rotary drive mechanisms, a multi-axis moving mechanism forklift assembly, and clearance gaps at the storage stations significantly reduces the space occupied by paint buckets on the workshop floor, optimizing the workshop production layout. Secondly, the rotary drive mechanism can drive the paint buckets to rotate continuously, preventing paint from settling during storage and eliminating the need for additional shaking before use, allowing the paint to be used immediately and significantly improving the efficiency of can body sheet metal coating printing. 2. The symmetrical distribution of the active and driven rollers provides balanced support for the paint buckets, preventing them from shifting during rotation. The design of the distance between the rollers being smaller than the diameter of the paint bucket ensures that the paint buckets are always in close contact with the rollers, preventing slippage and guaranteeing the continuity and stability of the paint bucket rotation. 3. The heating roller can maintain the paint in the paint bucket within a suitable temperature range according to the storage requirements of the paint. This avoids the paint viscosity from increasing in low-temperature environments, which would affect subsequent use, and further improves the mixing uniformity of the paint, ensuring the paint's stable state during use. 4. The sensor can accurately determine whether the storage station is empty and whether the carrier frame has successfully placed or removed the paint bucket, preventing the multi-axis moving mechanism from running idle or repeatedly placing the bucket, and preventing equipment malfunctions or safety hazards caused by inaccurate placement of the paint bucket.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please see Figures 1 to 6 A paint storage device for a can body sheet metal coating production line includes a multi-axis moving mechanism 1 and a three-dimensional storage rack 2. The multi-axis moving mechanism 1 is opposite to the three-dimensional storage rack 2. The three-dimensional storage rack 2 has multiple storage stations 21, each of which is equipped with a rotary drive mechanism 3. Paint buckets 5 are placed on the rotary drive mechanism 3, which drives the paint buckets 5 to rotate. A forklift assembly 4 is installed on the multi-axis moving mechanism 1, and the storage stations 21 have clearance gaps to allow the forklift assembly 4 to pick up and place the paint buckets 5. The multi-layer, multi-station design of the three-dimensional storage rack 2 significantly reduces the space occupied by the paint buckets 5 on the workshop floor, optimizing the workshop production layout. The rotary drive mechanism 3 can drive the paint buckets 5 to rotate continuously, preventing paint from settling during storage and eliminating the need for additional shaking before use, allowing the paint to be used immediately after opening, significantly improving the efficiency of can body sheet metal coating and printing production. The multiple storage stations 21 are arranged in an array.

[0023] Please see Figures 1 to 3Preferably, the rotary drive mechanism 3 includes a driving roller 31 and a driven roller 32, which are symmetrically arranged on both sides of the storage station 21. The distance between the driving roller 31 and the driven roller 32 is less than the diameter of the paint bucket 5. The symmetrical distribution of the driving roller 31 and the driven roller 32 provides balanced support for the paint bucket 5, preventing it from shifting during rotation. The design that the distance between them is less than the diameter of the paint bucket 5 ensures that the paint bucket 5 is always in close contact with the rollers, preventing slippage and ensuring the continuity and stability of the paint bucket 5's rotation.

[0024] Please see Figures 1 to 3 Preferably, the driving roller 31 and the driven roller 32 are driven by a geared motor 33. The driving roller 31 is fixedly connected to a pulley, and the driven roller 32 is fixedly connected to a pulley. A synchronous belt connects the two pulleys. Alternatively, the geared motor 33 can drive only the driving roller 31 to rotate, without driving the driven roller 32 to rotate via the synchronous belt.

[0025] Please see Figures 1 to 3 Preferably, each storage station 21 is symmetrically provided with support frames 34 on both sides. Bearing seats are installed on the support frames 34. The driving roller 31 and the driven roller 32 are rotatably connected to the bearing seats on the corresponding sides. The distance between the support frames 34 is greater than the distance between the driving roller 31 and the driven roller 32. This provides stable support and rotational constraint for the rollers, reduces frictional resistance when the rollers rotate, and the greater distance between the support frames 34 than the roller distance provides space for the forklift assembly 4 to extend into the clearance gap, and avoids interference of the support frames 34 with the rotation of the paint bucket 5.

[0026] Please see Figures 1 to 3 Preferably, the driven roller 32 is a heating roller. The heating roller can maintain the paint in the paint bucket 5 within a suitable temperature range according to the storage requirements of the paint. On the one hand, it avoids the paint viscosity from increasing in a low-temperature environment, which would affect subsequent use. On the other hand, it can further improve the mixing uniformity of the paint and ensure the stability of the paint during use.

[0027] Please see Figures 1 to 6 Preferably, the fork-taking assembly 4 includes two forks 41 and a fork drive 42. The fork drive 42 is mounted on the multi-axis moving mechanism 1, and the forks 41 are mounted on the fork drive 42. The fork drive 42 drives the forks 41 to extend and retract, thereby achieving stable picking and placing of the paint bucket 5. The fork-taking assembly 4 can use existing automated storage and retrieval system (AS / RS) forks 41, which are existing technologies and will not be described in detail here.

[0028] Please see Figures 1 to 6Preferably, the distance between the two forks 41 is less than the distance between the driving roller 31 and the driven roller 32. This ensures that the forks 41 can smoothly extend into the gap between the driving roller 31 and the driven roller 32 to accurately pick up or place the paint bucket 5, avoiding interference with the rollers.

[0029] Please see Figures 1 to 6 Preferably, the multi-axis moving mechanism 1 is provided with a support frame 11, which is U-shaped. The forklift assembly 4 is installed on the bottom surface inside the support frame 11. The multi-axis moving mechanism 1 can drive the planar displacement of the support frame 11. The distance between the two arms of the support frame 11 is greater than the diameter of the paint bucket 5. This provides protection for the forklift assembly 4 and the paint bucket 5, preventing the paint bucket 5 from shaking or falling during transportation. At the same time, the distance between the two arms is greater than the diameter of the paint bucket 5, ensuring that the paint bucket 5 can be smoothly placed into the support frame 11. The multi-axis moving mechanism 1 is a mature existing device and will not be described in detail or have specific protection requirements.

[0030] Please see Figures 1 to 6 Preferably, each storage station 21 is equipped with a through-beam sensor 6 to detect whether a paint bucket 5 is present in the storage station 21; the carrier frame 11 is also equipped with a through-beam sensor 6 to detect whether a paint bucket 5 is present in the carrier frame 11. The sensors can accurately determine whether the storage station 21 is empty and whether the carrier frame 11 has successfully placed or removed a paint bucket 5, avoiding the multi-axis moving mechanism 1 from running empty or repeated placement, and preventing equipment failure or safety hazards caused by inaccurate placement of the paint bucket 5. The through-beam sensor at the storage station is used to detect whether there is a paint bucket inside; if there is, it controls the rotary drive mechanism to rotate the paint bucket; if not, it controls the rotary drive mechanism 3 to stop working.

[0031] Preferably, a material retrieval rack can be set up at a designated location in the factory to facilitate the multi-axis drive mechanism to drive the forklift assembly 4 to pick up and put down the paint buckets 5 (to facilitate the temporary storage of the paint buckets 5 in the three-dimensional storage rack 2 when the paint arrives, and to temporarily place the paint buckets 5 for easy access by the staff when needed). The loading rack and the material retrieval rack can be set up with rollers in the form of a single storage station 21, except that they will not rotate actively and do not need to drive the paint buckets 5 to rotate.

[0032] The working principle of this utility model is as follows: Paint bucket storage: The operator places the paint bucket 5 to be stored in the designated loading area. After receiving the storage instruction, the multi-axis moving mechanism 1 drives the carrier frame 11 to move to the loading area. The fork drive 42 drives the two forks 41 to extend, and the forks 41 are inserted from the bottom of the paint bucket 5. Then the multi-axis moving mechanism 1 rises and lifts the paint bucket 5. Subsequently, the fork drive 42 retracts the forks 41, so that the paint bucket 5 is located inside the bearing frame 11. After the through-beam sensor 6 inside the support frame 11 detects the paint bucket 5, it sends a signal to the control system. The control system controls the multi-axis moving mechanism 1 to drive the support frame 11 to move towards the three-dimensional storage rack 2. At the same time, based on the empty space information of the three-dimensional storage rack 2, it locates the target storage station 21. The multi-axis moving mechanism 1 adjusts the position of the bearing frame 11 so that the fork 41 is aligned with the clearance of the storage station 21. Then, the fork drive 42 drives the fork 41 to extend and place the paint bucket 5 onto the rotary drive mechanism 3 (drive roller 31 and driven roller 32) of the storage station 21. Then, the multi-axis moving mechanism 1 moves down a certain distance and disengages from the paint bucket 5, and the fork 41 can retract and exit. The through-beam sensor 6 at storage station 21 detects the paint bucket 5 and sends a "placement successful" signal to the control system. The multi-axis moving mechanism 1 drives the carrier frame 11 to reset, completing one placement of the paint bucket 5.

[0033] Storage maintenance: After the paint bucket 5 is placed on the rotary drive mechanism 3, the reduction motor 33 starts and drives the active roller 31 to rotate through the pulley and synchronous belt. The active roller 31 further drives the driven roller 32 to rotate synchronously. Since the distance between the active roller 31 and the driven roller 32 is smaller than the diameter of the paint bucket 5, the paint bucket 5 rotates slowly with the roller under the action of the friction force of the roller, thus avoiding the precipitation of paint inside. If the ambient temperature is low (or the paint needs to be preheated), the heating rod built into the driven roller 32 can be activated. The heating roller transfers heat to the paint bucket 5, and the temperature controller maintains the paint temperature within a suitable range to ensure the paint condition is stable.

[0034] paint bucket taking When the can body sheet metal coating production line needs paint, the control system receives the picking instruction, the multi-axis moving mechanism 1 drives the bearing frame 11 to move to the front of the target storage station 21, the fork drive component 42 drives the fork 41 to extend, and the fork 41 extends into the bottom of the paint bucket 5 through the clearance of the storage station 21. The multi-axis moving mechanism 1 drives the carrier frame 11 to move upward a certain distance so that the paint bucket 5 is disengaged from the rotary driving mechanism 3. Then the forks 41 retract. After the sensor in the carrier frame 11 detects the paint bucket 5, the multi-axis moving mechanism 1 drives the carrier frame 11 to move towards the set paint taking area. Upon reaching the target location, the fork drive unit 42 extends the forks 41 and places the paint bucket 5 at the designated location in the supply area. The multi-axis moving mechanism drives the carrier frame 11 to move down a certain distance so that the forks 41 disengage from the paint bucket 5. The forks 41 retract, and the sensor inside the carrier frame 11 detects that there is no paint bucket 5. The multi-axis moving mechanism 1 drives the carrier frame 11 to reset, completing one paint bucket 5 retrieval.

[0035] Through the coordinated efforts of the above stages, this utility model achieves efficient storage, stable maintenance, and rapid retrieval of the paint bucket 5, effectively solving the problems of large space occupation and the need for additional shaking of the paint in traditional storage methods, and significantly improving the production efficiency of the can body sheet metal coating production line.
