Description

Technical Field

[0001] This utility model relates to the field of CTP plate technology, specifically to a CTP plate positioning device. Background Technology

[0002] CTP (computer-to-plate) technology is a plate-making technique that directly transfers digital data or pages edited in an electronic prepress system or color desktop printing system to a printing plate. This eliminates processes such as film output, manual plate assembly, and plate exposure, reducing human error, increasing production efficiency, meeting the demands of rapid printing, and lowering printing costs. Therefore, CTP technology is widely used in the printing industry. A CTP plate is a printing plate made using CTP technology. CTP plates can achieve high-resolution image and text transfer, ensuring the clarity and detail of printed materials. CTP plates are made using a plate-making machine. During the plate-making process, CTP plates are typically cut to the appropriate printing size. After cutting, the CTP plate is directly sent out of the cutting machine. To facilitate the transfer of CTP plates, multiple CTP plates are usually stacked together. This process relies on manual labor, requiring manual alignment of each CTP plate during stacking. This is not only time-consuming but also prone to unevenness and misalignment, especially when aligning larger CTP plates. Utility Model Content

Detailed Implementation

[0019] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] Reference Figures 1 to 4This utility model provides a CTP plate positioning device, including a first conveying and positioning module 1, a conveying and steering module 2 connected to the first conveying and positioning module 1, and a second conveying and positioning module 3 connected to the conveying and steering module 2. The CTP plate is rectangular after cutting. First, the first conveying and positioning module positions and aligns the CTP plate in one direction (defined as the X-axis direction). Then, the CTP plate passes through the conveying and steering module 2 and enters the second conveying and positioning module, where it is positioned and aligned in the other direction (defined as the Y-axis direction).

[0021] Both the first conveying and positioning module 1 and the second conveying and positioning module 3 include a first frame 11, a first conveying mechanism 12 disposed on the first frame 11, and a first positioning mechanism 13 and a second positioning mechanism 14 symmetrically disposed on the first frame 11. The conveying direction of the first conveying mechanism of the first conveying and positioning module 1 is perpendicular to the conveying direction of the first conveying mechanism 12 of the second conveying and positioning module 3. The first positioning mechanism 13 and the first frame 11 are movably connected, and the second positioning mechanism 14 and the first frame 11 are movably connected. The first frame 11 is also provided with a positioning drive mechanism 15 for driving the first positioning mechanism 13 and the second positioning mechanism 14 to move closer or further apart from each other. Taking the first conveying and positioning module as an example, the positioning drive mechanism 15 drives the first positioning mechanism 13 and the second positioning mechanism 14 to move closer or further apart from each other in the Y-axis direction. When they move closer together, they can contact the two sides of the CTP plate located on the first conveying mechanism 12, pushing the CTP plate to be centered and aligned.

[0022] Both the first positioning mechanism 13 and the second positioning mechanism 14 include a movable frame 131 movably connected to the first frame 11 and a positioning element 132 connected to the movable frame 131. The movable frame 131 and the positioning drive mechanism 15 are drively connected. Taking the first conveying and positioning module as an example, the first frame 11 has two crossbeams arranged along the Y-axis direction, and the movable frame 131 is movably connected between the two crossbeams. Specifically, the crossbeams are provided with guide rails for connecting the movable frame 131. The movable frame 131 is provided with a connector 133 for connecting the positioning drive mechanism 15.

[0023] The first conveying mechanism 12 includes a plurality of first conveying rollers 121 disposed on the first frame 11 and a first conveying drive assembly 122 disposed on the first frame 11. The first conveying drive assembly 122 and the first conveying rollers 121 are connected in a driving manner. The positioning member 132 is located above the first conveying rollers 121. In this embodiment, the movable frame 131 is located below the first conveying rollers 121, and there is a gap between adjacent first conveying rollers 121. A plurality of connecting plates are disposed on the movable frame 131, and the connecting plates pass through the aforementioned gaps and are connected to the positioning member 132.

[0024] like Figure 4 As shown, the positioning drive mechanism 15 includes a first rotating shaft 151 connected to the first frame 11 and a positioning drive component 152 disposed on the first frame 11. The positioning drive component 152 is connected to the first rotating shaft 151 through a transmission 153, and the first rotating shaft 151 is connected to the moving frame 131 in a transmission connection. The first rotating shaft 151 and the movable frame 131 are connected by a transmission chain (the transmission chain is not shown in the figure to avoid obstruction). Specifically, sprockets are provided on both sides of the Y-axis direction of the first frame 11 and on the first rotating shaft 151, so that the transmission chain forms a closed shape. The connecting piece 133 on the movable frame 131 is fixedly connected to the transmission chain. The connecting piece 133 of the first positioning mechanism 13 is located at the bottom of the movable frame 131 and is connected to the lower part of the transmission chain. The connecting piece 133 of the second positioning mechanism 14 is located at the upper part of the movable frame 131 and is connected to the upper part of the transmission chain. When the first rotating shaft 151 rotates, the transmission chain rotates accordingly. At this time, the movable frame 131 of the first positioning mechanism 13 and the movable frame 131 of the second positioning mechanism 14 can move closer or further away from each other. That is, the positioning piece 132 of the first positioning mechanism 13 and the positioning piece 132 of the second positioning mechanism 14 can move closer or further away from each other, thereby achieving the centering and alignment of the CTP plate.

[0025] The conveying and steering module 2 includes a second frame 21, a plurality of second conveying rollers 22 disposed on the second frame 21, a lifting mechanism 23 connected to the second frame 21, a plurality of steering conveying mechanisms 24 disposed on the lifting mechanism 23, and a second conveying drive assembly 25 for driving the second conveying rollers 22. The lifting mechanism 23 is located below the second conveying rollers 22, and there is a gap between adjacent second conveying rollers 22 for the steering conveying mechanisms 24 to pass through. Of course, in actual implementation, not every gap needs to be provided with a corresponding steering conveying mechanism 24. In this embodiment, five steering conveying mechanisms 24 are provided. There is one second conveying roller 22 between the first and second steering conveying mechanisms 24, two second conveying rollers 22 between the second and third steering conveying mechanisms 24, two second conveying rollers 22 between the third and fourth steering conveying mechanisms 24, and one second conveying roller 22 between the fourth and fifth steering conveying mechanisms 24.

[0026] In this embodiment, both the first conveying drive assembly 122 and the second conveying drive assembly 25 include a motor and a transmission chain, and the ends of the first conveying roller 121 / second conveying roller 22 are provided with sprockets that cooperate with the transmission chain.

[0027] The conveying direction of the second conveyor roller 22 is the same as that of the first conveying and positioning module, and the conveying direction of the steering conveyor mechanism 24 is the same as that of the second conveying and positioning module. After the CTP plate has fully entered the second conveyor roller 22, the lifting mechanism 23 drives the steering conveyor mechanism 24 to rise, causing the conveyor belt to contact the bottom of the CTP plate. The steering conveyor mechanism 24 then sends the CTP plate into the second conveying and positioning module. After the conveying is completed, the lifting mechanism 23 resets.

[0028] The lifting mechanism 23 includes a base plate 231 connected to the second frame 21, a lifting drive component 232 disposed on the base plate 231, and a lifting plate 233 connected to the output end of the lifting drive component 232. The steering and conveying mechanism is disposed on the lifting plate 233. In this embodiment, the lifting drive component 232 is a cylinder.

[0029] The steering and conveying mechanism 24 includes a conveying bracket 241 disposed on the lifting mechanism 23, a conveyor belt 242 disposed on the conveying bracket 241, and a steering drive assembly 243 disposed on the lifting mechanism 23 for driving the conveyor belt.

[0030] The steering drive assembly 243 includes a second rotating shaft 243a disposed on the lifting mechanism 23 and a reversing drive member 243b disposed on the lifting mechanism 23 for driving the second rotating shaft 243a to rotate. The second rotating shaft 243a and the conveyor belt 242 are connected in a transmission manner.

[0031] In specific implementation, the first conveying positioning module, the second conveying positioning module, and the conveying steering module 2 can be equipped with sensors (such as photoelectric sensors) to detect the CTP plate and determine whether the CTP plate is in position. During operation, the pre-stacked CTP plates are fed onto the first conveying roller 121 of the first conveying positioning module via a conveying mechanism. The first positioning mechanism 13 and the second positioning mechanism 14 of the first conveying positioning module move closer together, pushing the CTP plate to move and completing the positioning alignment in the first direction. Then, the CTP plate enters the second conveying roller 22 of the conveying steering module 2. The lifting mechanism 23 drives the steering drive mechanism to rise, sending the CTP plate into the second conveying positioning module. The first positioning mechanism 13 and the second positioning mechanism 14 of the second conveying positioning module move closer together, pushing the CTP plate to move and completing the positioning alignment in the second direction. Afterward, the second conveying positioning module can send the positioned and aligned CTP plate into the conveying mechanism for transmission to the next work station.
