Description

Technical Field

[0001] The utility model relates to the technical field of book and periodical printing, in particular to a bottom support device used for automatic loading and unloading of rotary printing equipment. Background Art

[0002] At present, the printing industry is developing rapidly and has begun to develop towards intelligence. Among them, automatic loading and unloading of rotary printing has become a trend, and mature technologies are available for implementation. However, this technology is only for finished roll paper. Once it involves residual materials, it means that the production plan of printing copies is reached soon after the printing is started, and the residual materials are not enough for the residual roll after the shutdown. The residual materials need to be recycled according to the company's production scheduling and MES system, because it can continue to be printed in the next production when there are similar paper requirements. At present, the automated processing means for recycling the residual materials are insufficient and manual intervention is required, resulting in breakpoints in the automation process, which are specifically manifested as follows:

[0003] First, the automatic paper loading mechanism is usually a paper loading vehicle equipped with a V-shaped chain plate (taking the automatic paper loading method of the V-shaped chain plate as an example). The lifting stroke is limited during the automatic paper connection or automatic paper unloading process, which cannot meet the stroke requirements of the roll remnant with a diameter of less than 700mm, and manual intervention is required to assist in unloading; secondly, whether it is a forklift AGV or a manual forklift to manually shift to the warehouse or from the warehouse to the on-site buffer area, it cannot be implemented because there are requirements between the fork plates. For the remnant of the diameter within 300-700mm, it cannot be directly forked, and can only be placed horizontally on the fork plate of the forklift by manual means. The above operations not only require a lot of manpower, but also greatly reduce the overall efficiency of printing.

[0004] In view of the above defects, there is a similar problem in the market. One solution is to modify the flat bottom support, add a V-shaped groove in the middle, dig a pit on the ground and install a hydraulic device, and add a bumping and turning system at the end of the conveying. Simply put, the hydraulic device in the pit is lowered so that the bottom support plane is level with the ground or slightly lower than the ground. After the remaining roll arrives, it is bumped and turned from the side to roll the remaining roll into the V-shaped groove on the bottom support and fix it. If the paper roll diameter is ≥800mm and meets the forklift plug plate spacing requirements, the forklift will directly grab and fork it away. If it does not meet the diameter of less than 800mm, the hydraulic lifting is increased, so that the bottom support and the remaining paper roll on it are raised above the ground level, and then the forklift will fork the paper roll together with the bottom support. Obviously, the above operation method not only causes a certain degree of damage to the ground, but also limits the unloading of paper rolls when the diameter is less than 800mm. The utility model is proposed based on the above research background, and aims to provide a bottom support device for automatic loading and unloading of rotary printing equipment to meet actual use needs.

More importantly, it achieves full automation without human intervention throughout the process, saving 2 workers on site, a total of 4 people in the day and night shifts, which is simple and reliable. More importantly, if a roll paper vertical warehouse is installed, it can be directly placed in the vertical warehouse with the help of a stacking robot arm, without the need to separately open the pallet storage area of ​​the above-mentioned technology, which is convenient for efficient management and implementation.

[0021] The following is combined with Figure 1-6 The utility model describes in detail the structure of a bottom support device for automatic loading and unloading of rotary printing equipment.

[0022] A base support device for automatic loading and unloading of rotary printing equipment, wherein the top of the base support device 5 is provided with a V-shaped groove for placing the excess of a paper roll 3; the bottom of the base support device is arranged on a paper roll upper cart 4, and the paper roll on the top of the base support device is transported to the paper receiving arm 2 at the paper feeder frame 1 of the rotary printing equipment by the paper roll upper cart; the base support device is also provided with a fork hole for cooperating with the fork arm of a forklift.

[0023] Embodiment 1 of the bottom support device:

[0024] The base support device comprises a horizontally placed columnar base support body, the bottom of the columnar base support body is an arc-shaped structure, the top of the columnar base support body is a plane, the V-shaped groove is arranged at the top center of the columnar base support body, and the length direction of the V-shaped groove is the same as the length direction of the columnar base support body. The forklift is a flat-tooth forklift, the number of the fork holes 7 is at least 2, and they are symmetrically arranged on the left and right sides of the columnar base support body, and the length direction of the fork holes is the same as the length direction of the columnar base support body.

[0025] Embodiment 2 of the bottom support device:

[0026] The base support device includes a horizontally placed columnar base support body, the axial cross section of the columnar base support body is an inverted frustum-shaped structure with an arc-shaped protrusion in the middle of the bottom, the V-shaped groove is arranged at the top center of the columnar base support body, and the length direction of the V-shaped groove is the same as the length direction of the columnar base support body. The left and right sides of the columnar base support body are provided with a balancing wheel assembly 9, the forklift is a ground bull forklift, and the left and right sides of the arc-shaped protrusion are provided with ground bull forklift fork holes 8 that cooperate with the fork arms of the ground bull forklift. The balancing wheel assembly includes at least a wheel arm, one end of which is connected to the side wall of the columnar base support body and the other end of which is provided with a roller.

[0027] The method of using the above-mentioned bottom bracket device of the utility model is as follows:

[0028] When there is no automatic paper feed Figure 1 As shown in the position, the automatic paper loading vehicle 4 carries the base paper roll 3 through the bottom support device and moves it to the measured position of the cut-off area, and lifts it to the specified height as shown in the figure. Figure 2 As shown, the receiving arm 2 moves downward to the specified area and aligns with the center of the base paper roll. The arm 2 automatically extends from both sides to clamp the paper core in the center of the roll paper. The vehicle on the upper side automatically rises and falls and returns to its original position. Figure 3 As shown, the paper splicing process is over. Since the diameter of the residual paper roll of the base paper drum is unpredictable and depends on the actual production completion, it is a very complicated problem to set the rotation and lifting position of the arm and the height of the paper loading vehicle according to the paper roll diameter. Once the paper splicing arm is inaccurate, it will damage the paper core, causing waste and unusability. However, the paper splicing arm can be predicted and controlled within the range of 600-1000mm of the paper roll diameter. Therefore, when there is residual material that needs to be automatically loaded, such as Figure 4 The bottom support mechanism 5 of the present design is shown as carrying the residual paper roll 3. After it reaches the corresponding position through the V-shaped chain plate conveyor belt 6 on the paper loading vehicle 4, the whole height meets the requirements, so it can be automatically loaded according to the whole process. Figure 1 Figure 2 Figure 3The process shown completes the automatic loading process, and the unloading process is the reverse of the above process and is not repeated here. The automatic loading and unloading of the remaining materials is fully realized.
