Description

Technical Field

[0001] This utility model relates to the field of CTP plate technology, specifically to a CTP plate flipping 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 CTP plate-making machine. After a CTP plate is produced, it flows out of the machine's outlet and slides naturally, which can lead to the plates scattering randomly. Currently, after the CTP plates flow out of the outlet, workers typically transfer them one by one to a designated stacking position. However, this method requires manual waiting to retrieve the plates, and each plate-making machine needs a worker present, which is time-consuming, labor-intensive, and costly. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Example 1

[0025] Reference Figures 1 to 3 This utility model provides a CTP plate flipping device, which includes a frame 1, a receiving frame 2 mounted on the frame 1, a flipping mechanism 3 mounted on the receiving frame 2, and a receiving and storing mechanism 4 mounted on the frame 1. The receiving frame 2 is connected to the discharge port of the plate-making machine. After the completed CTP plate flows out of the discharge port of the plate-making machine, it flows into the receiving frame 2. The flipping mechanism 3 on the receiving frame 2 flips the CTP plate to the receiving and storing mechanism 4 for temporary storage.

[0026] The flipping mechanism 3 includes a first rotating shaft 31 connected to the receiving frame 2, a plurality of flipping frames 32 disposed on the first rotating shaft 31, and a first driving component 33 for driving the first rotating shaft 31. In this embodiment, the first driving component 33 is a motor, which drives the flipping frames 32 to rotate, thereby flipping the CTP plate. The receiving and storing mechanism 4 includes a second rotating shaft 41 disposed on the frame 1, a storing frame 42 connected to the second rotating shaft 41, and a flipping drive assembly 43 disposed on the frame 1 for driving the second rotating shaft 41. Figure 1 Taking the perspective of the receiving machine as an example, the receiving machine is tilted to the left relative to the horizontal plane, and the flipping frame 32 of the receiving and storage mechanism 4 is initially tilted to the right relative to the horizontal plane. After the CTP plate enters the receiving frame 2, it can slide to the flipping mechanism 3. The flipping mechanism 3 flips the CTP plate, and the CTP plate falls onto the storage frame 42 of the receiving and storage mechanism 4.

[0027] The flipping drive assembly 43 includes a drive bracket 431 connected to the frame 1, a second drive member 432 disposed on the drive bracket 431, and a transmission assembly 433 connected to the output end of the second drive member 432. The transmission assembly 433 is connected to the second rotating shaft 41. In this embodiment, the second drive member 432 is a motor, and the transmission assembly 433 mainly includes a gear set and a worm gear. The output end of the motor is connected to the second rotating shaft 41 through the gear set and the worm gear. The worm gear has a self-locking function, which facilitates the stability of the plate storage rack 42 at a set angle. In addition, a limiting strip 45 is provided at the lower end of the plate storage rack 42. The limiting strip 45 can support the CTP plate and prevent the CTP plate from slipping off the plate storage rack 42.

[0028] A conveying assembly 44 is provided on the plate storage rack 42. The conveying assembly 44 includes a conveyor belt 441 disposed on the plate storage rack 42 and a third driving member 442 for driving the conveyor belt 441. The third driving member 442 is a motor. Multiple conveyor belts 441 can be provided. In this embodiment, four are evenly arranged. After the CTP plates are flipped onto the plate storage rack 42 and accumulated to a set number, the second driving member 432 drives the plate storage rack 42 to rotate downward, so that the plate storage rack 42 rotates to a horizontal angle or tilts downward relative to the horizontal angle. Then, the third driving member 442 drives the conveyor belt 441 to send the CTP plates out for rough handling, which facilitates the transfer operation of CTP plates (for example, a set of CTP plates has a total of 10 sheets. Once 10 sheets are accumulated, they can be transferred).

[0029] The flipping frame 32 includes a connector 321 connected to the first rotating shaft 31 and an L-shaped bracket 322 connected to the connector 321. Multiple L-shaped brackets 322 are arranged side by side. When the first rotating shaft 31 rotates, multiple L-shaped brackets 322 rotate synchronously, thereby enabling the CTP plate to be flipped.

[0030] A receiving plate 21 is provided on the receiving frame 2. The receiving plate 21 has an opening 22 for accommodating the L-shaped bracket 322. The long side of the L-shaped bracket 322 is located within the opening 22. The top surface of the receiving plate 21 and the top surface of the long side of the L-shaped bracket are on the same plane. The receiving plate 21 can support the CTP plate entering the receiving frame 2. The CTP plate slides down along the receiving plate 21 until its edge contacts the L-shaped bracket 322.

[0031] The receiving frame 2 has a receiving roller 23 at its starting end, and a fourth driving component 24 for driving the receiving roller 23 to rotate. The fourth driving component 24 is a motor. The receiving roller 23 contacts the bottom surface of the CTP plate, driving the CTP plate to move and ensuring it reaches the predetermined position for successful flipping. In a further implementation, several sensors, such as fiber optic sensors, can be installed on the receiving plate 21 to monitor whether the CTP plate has reached the predetermined position.

[0032] A guide member 11 is provided on the frame 1, and a guide portion that cooperates with the guide member 11 is provided on the frame of the plate storage rack 42. An arc-shaped guide hole is provided on the guide member 11, and the guide portion is inserted into the arc-shaped guide hole. The center of the arc-shaped guide hole coincides with the rotation axis of the plate storage rack 42. The cooperation between the guide portion and the guide member 11 makes the rotation process of the plate storage rack 42 more stable.

[0033] The CTP plate flipping device also includes a discharge conveyor line 5, which is located on one side of the frame 1. After accumulating a predetermined number of CTP plates (or a set of CTP plates), the plate storage rack 42 flips downwards. At this time, the conveying component 44 can send the CTP plates into the discharge conveyor line 5, which then transports them to the next work station. This eliminates the need for manual stacking and handling of each plate, resulting in high efficiency and low labor intensity.

[0034] During operation, the receiving frame 2 connects with the receiving port of the plate-making machine. After the CTP plate flows out of the plate-making machine's outlet, it falls into the receiving rack and slides to a predetermined position. Then, the flipping mechanism 3 flips the CTP plate, causing it to fall onto the plate storage rack 42, completing the flipping of a single CTP plate. Subsequently, as more CTP plates flow out of the plate-making machine, the flipping mechanism 3 stacks the CTP plates one by one onto the plate storage rack 42. After the plate storage rack 42 accumulates a set number of CTP plates, the plate storage rack 42 of the receiving and storage mechanism 4 rotates downward, and the conveying component 44 on the plate storage rack 42 sends the entire stack of CTP plates into the discharge conveyor line 5, which then transports them to the next work station.

[0035] Example 2

[0036] Reference Figure 4In this embodiment, the CTP plate flipping device further includes a transfer cart 6 disposed on one side of the rack 1. The transfer cart 6 can be equipped with a tray for storing CTP plates. After accumulating a predetermined number of CTP plates (or after accumulating one set of CTP plates), the plate storage rack 42 flips downwards to below a horizontal angle. At this time, the conveying component 44 can deliver the CTP plates onto the tray of the transfer cart 6. Subsequently, the worker can use the transfer cart 6 to transport the complete set of CTP plates to the next workstation, or continue to stack an empty tray on the current tray, waiting to place the next set of CTP plates. After repeating the above operation and stacking several trays, the plates are transferred in batches. The other structural parts of this embodiment are consistent with Embodiment 1, and will not be described in detail here.

[0037] This utility model is equipped with a flipping mechanism 3 and a receiving and storing mechanism 4. After the CTP plates flow out of the plate-making machine's outlet, they are flipped and stacked one by one by the flipping mechanism 3 onto the storage rack 42 of the receiving and storing mechanism 4. After stacking a set number of CTP plates, the receiving and storing mechanism 4 rotates to send the CTP plates out of the storage rack 42. No manual intervention is required at all times, and one worker can supervise multiple plate-making machines, which improves work efficiency and reduces production costs.
