Description

Technical Field

[0001] The invention relates to the field of transportation or storage devices, and in particular to a CTP plate storage and retrieval turnover device and method. Background Art

[0002] CTP (Computer-to-Plate) is an important technology in the modern printing industry. It refers to the process of transferring image information directly to the printing plate through a computer. Compared with traditional printing plate making methods, CTP technology has many advantages and is widely used in commercial printing, packaging printing and publishing. It is generally a four-color plate (cyan, magenta, yellow and black (CMYK)).

[0003] Before CTP printing, it is necessary to make plates first. In traditional printing factories, after the plates are made, they are directly transported to the printing workshop for printing. The temporary placement of the plates is completed by using movable plate racks. There is no device that can store more plates at one time. When the printing task is busy, the platemaking machine may not be able to supply the production of the printing press, and the labor intensity of the personnel is relatively high. Although there are devices for automatic plate supply, due to the lack of storage devices, large-scale plate making is not possible, which restricts the effective application of automatic plate supply devices, is not conducive to the maintenance of platemaking machines, and greatly affects production efficiency. At present, when the production task of the workshop is heavy, it is necessary to manually collect some of the CTP plates that have been made and transport them to the corresponding printing presses. For the personnel, the labor intensity is greatly increased, and it is easy to cause damage to the plates, which is not conducive to reducing the production and operation costs.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0022] See also Figure 1-Figure 5 This embodiment provides a CTP plate storage and retrieval turnover device, including a warehouse body 0, which is a rectangular parallelepiped structure, and the internal support is composed of a metal frame. The warehouse body 0 includes a warehouse position 1, a plate rack 2, a slide rail 3, and a mechanical arm 4.

[0023] Bin 1 is located inside bin body 0 and is composed of a plate storage unit consisting of multiple plate racks and cavities, forming a semi-enclosed independent bin with one side open, which can reduce the adhesion of dust and other impurities to the CTP plate, improve the quality of printed products, and reduce losses.

[0024] The warehouse frame 24 is fixedly mounted on the bracket of the warehouse body 0, that is, fixedly mounted inside the warehouse position 1. The warehouse frame 24 includes: The buffer mechanism 26 is fixedly mounted on one side of the opening of the plate storage rack 24 (i.e., the side elevation of the plate storage rack 24), and is set as an inclined surface. The material of the buffer mechanism 26 is preferably a sensitive elastic rubber material, which protects the plate material and reduces the damage to the plate material caused by the edge of the plate storage rack 24 when the CTP plate is stored. At the same time, it can also guide the CTP plate to enter and exit the storage position 1; Multiple pulleys 9, multiple rotating shafts are fixedly installed on the magazine frame 24, and the rollers 9 are rotatably installed with the rotating shafts, such as Figure 4 As shown, a plurality of rollers 9 are provided in a group and are arranged horizontally; when the CTP plate is placed on the magazine plate rack 24, the bottom is in contact with the rollers 9.

[0025] The slide bar 21 is fixedly installed inside the plate storage rack 24. Generally, more than two slide bars are arranged horizontally. When used in conjunction with the pulley 9, the CTP plate can be smoothly stored in and taken out, reducing damage to the CTP plate. A photoelectric sensor switch 22 is arranged on the closed side of the plate storage rack 24 to sense the position of the CTP plate when storing and taking out the plate.

[0026] The slide rail 3 is fixedly arranged at the lower part of the warehouse body 0 , the slide rail 3 is arranged parallel to the warehouse position 1 , and the plate rack 2 is slidably arranged on the slide rail 3 .

[0027] The plate frame 2 includes a plate surface 25, a support frame 23, a push piece 5, a roller 9, a photoelectric sensor switch 22, a slide bar 21, a drive motor 8, a stepper motor 7, and a slide table 6; the support frame 23 is slidably mounted on the slide rail 3; The driving motor 8 is fixedly installed at the bottom of the support frame 23, and a chain is rotatably installed on the outer side of the slide rail 3. The chain is fixedly connected to the support frame 23, and the chain is used to drive the support frame 23 to slide on the slide rail 3, thereby moving the plate frame 2. That is, the driving motor 8 drives the chain to drive the plate frame 2 to slide on the slide rail 3, and transport the CTP plate to the robot arm 4 or the bin 1.

[0028] The plate 25 is fixed on the support frame 23, and the plate 25 is tilted. The tilt angle of the plate 25 is 70-90 degrees. A plurality of rollers 9 are horizontally arranged at the bottom of the plate 25. The rollers 9 are arranged in a straight line and can rotate on the plate 25, and cooperate with the plate 25 to carry the CTP plate. At least two slide bars 21 are arranged on the plate 25 at intervals. The slide bars 21 are also arranged horizontally and cooperate with the rollers 9 to reduce friction when the CTP plate is pushed from the plate frame 2 to the warehouse 1 or taken out from the warehouse 1 to the plate frame 2, thereby reducing damage to the CTP plate.

[0029] The slide 6 is fixedly mounted on the support frame 23 and is located on one side of the plate 25. A slide groove 1 corresponding to the slide 6 is opened in the lower middle part of the plate 25. One end of the push piece 5 is mounted on the slide 6 through a screw rod. One end of the push piece 5 is located in the slide groove 1. A stepper motor 7 is fixedly mounted on the bottom of the support frame 23. The stepper motor 7 is connected to the screw rod of the slide 6 through a belt, driving the push piece 5 to slide horizontally in the slide groove 1. A plate clamp 53 is rotatably mounted on the open end of the push piece 5 for clamping the CTP plate. A photoelectric sensor switch 22 is fixedly mounted on the end of the slide 6 away from the bin 1 for sensing the position of the push piece 5.

[0030] A photoelectric sensor switch 22 is provided at the center of the plate surface 25 to sense whether there is a CTP plate on the plate frame 2 .

[0031] In this embodiment, the mechanical arm 4 is installed at one end of the warehouse body 0, and the warehouse body 0 is provided with a plate transport frame 19 fixedly installed at one end of the mechanical arm. The movable end of the mechanical arm 4 is provided with a plate clamp 2 4-1, which is used to grab the CTP plate on the plate transport frame 19 and transfer it to the plate frame 2, or grab the CTP plate on the plate frame 2 and transfer it to the plate transport frame 19; the plate frame 2, the mechanical arm 4 and the plate transport frame 19 constitute a CTP plate storage and access structure to realize the storage, access and transportation of the CTP plate.

[0032] A central control console 20 is also fixedly arranged on the warehouse body 0, and the electrical signal is connected to the plate-making equipment system, the printing workshop system, and the CTP plate storage and retrieval plate turnover device system, which is used to control the movement of the plate rack 2. That is to say, in this application, the warehouse body 0 is located between the plate-making equipment and the printing press, and is used as a device for temporarily storing CTP plates and temporarily caching CTP plates.

[0033] In this embodiment, a number is set above each cavity of the bin 1, and the bin 1 updates the cavity information to the central console 20 in real time through electrical signals.

[0034] When storing the plate in the storage bin 1, the central control console 20 receives the electrical signal from the plate transport rack 19, and sends electrical signals to the mechanical arm and the plate rack 2 at the same time. When the plate transport rack 19 moves to the position of the mechanical arm 4 inside the bin body 0, the mechanical arm 4 is triggered to work, and the plate grabbing arm is adjusted to the CTP plate position of the plate transport rack. The plate clamp 4-1 clamps the CTP plate and puts the plate on the roller 9 of the plate rack 2. The mechanical arm 4 returns to its original position, and the photoelectric sensor switch 22 senses the CTP plate and triggers the plate rack 2 to work. The drive motor 8 drives the chain to drive the plate rack 2 to slide on the slide rail 3 to the cavity position corresponding to the storage bin 1, and the push piece 5 clamps the CTP plate. The stepper motor 7 drives the screw rod to rotate and drive the push piece 5 to slide, and pushes the plate into the cavity. The push piece 5 and the plate rack 2 return to their original positions one after another.

[0035] When taking the plate from the storage bin 1, the control system of the printing press releases the plate taking information and transmits it to the central control console 20 through an electrical signal. The central control console 20 simultaneously sends the electrical signal to the mechanical arm 4, the plate frame 2 and the plate transport frame 19, and the driving motor 8 drives the chain to drive the plate frame 2 to the cavity of the corresponding storage bin 1, and the stepping motor 7 drives the screw rod to rotate and drives the push piece 5 to slide to the position of the storage bin 1. The plate clamp on the push piece 5 clamps the CTP plate, and the stepping motor 7 drives the screw rod to rotate in the reverse direction, driving the push piece 5 to move and make the CTP plate slide on the roller 9 until the entire CTP plate is on the plate surface 25. The plate clamp of the push piece 5 is released, and the photoelectric sensor switch 22 corresponding to the push piece 5 on the slide 6 senses the push piece 5, triggering the driving motor 8 to drive the chain to move, so that the plate frame 2 moves to the vicinity of the mechanical arm 4, the mechanical arm 4 rotates, and the plate clamp arm moves to the CTP on the plate frame 2, and the plate clamp 4-1 clamps the CTP plate and transfers the plate to the plate transport frame 19, and the mechanical arm 4 returns to its original position. At this point, the entire cycle of storing and retrieving the plate is completed.

[0036] In combination with the above-mentioned embodiment, a CTP plate storage and retrieval turnover method is also disclosed, comprising the following steps: S1: the plate making machine receives a production scheduling signal, the corresponding plate making machine completes plate making, and at the same time transmits the production scheduling information electric signal to the central control console, and the production system sends the printing machine plate taking information and the machine vacancy information electric signal to the central control console; S2: The buffer warehouse transmits the warehouse location information to the central control console and production control system in real time through electrical signals; S3: The central console receives signals from the plate making and printing control systems, retrieves the position information, transmits it to the storage and retrieval mechanism control system, and successively triggers the transfer mechanism control system and the plate transport rack control system; S4: When the CTP plate is stored, when it is transported to the turnover device, the electric signal controls the transfer mechanism to grab the CTP plate on the plate transport rack and transfer it to the storage and retrieval mechanism; the storage and retrieval mechanism receives the CTP plate on the transfer mechanism, moves to the corresponding storage position according to the storage position information transmitted by the buffer warehouse, and pushes the CTP plate into the storage position; When taking the plate, the storage and retrieval mechanism receives the electrical signal from the central control console, moves to the corresponding position, grabs the CTP plate and moves to the transfer mechanism. The transfer mechanism grabs the plate on the storage and retrieval mechanism and transfers it to the plate transport rack. After the grabbing is completed, the transfer mechanism returns to its original position. S5: After the access is completed, the access mechanism returns to its original position; During the whole process, the plate transport rack control system receives the plate transport electrical signal and transports the CTP plate. This process repeats and completes the plate storage and plate retrieval process.

[0037] In this embodiment, two plate clamps and a cylinder are installed on the pusher 5. A rotating shaft is slidably installed on the pusher 5 (i.e., a shaft groove for installing the rotating shaft is opened on the pusher 5, and the rotating shaft is slidably installed in the rotating shaft). The two plate clamps are rotatably installed on the rotating shaft. The cylinder is a double-headed cylinder, and the cylinder body of the cylinder is fixedly installed on the pusher 5. The two ends of the cylinder are rotatably connected with the two plate clamps respectively. When the cylinder is extended and retracted, it can rotate with the two plate clamps to achieve the clamping of the CTP plate (not shown in the figure). A photoelectric sensor (i.e., a photoelectric sensor switch) is also installed at the plate clamp of the pusher 5 to detect whether the CTP plate is clamped. Its function is the same as that of the Chinese patent with announcement number CN221164887U.

[0038] In this embodiment, the specific storage and retrieval method of the CTP plate is as follows: the plate-making machine receives the plate-making signal, and a set of plates (4 or 8 plates) are made in order. The plate-turning rack turns the CTP plate to the lower plate-transporting rack, and sends it to the cache position via the conveyor. The mechanical arm receives the electrical signal, and then absorbs the CTP plate on the conveyor and places it on the plate rack 2 of the storage and retrieval plate structure. The lower end of the CTP plate contacts the roller 9. The storage and retrieval plate structure receives the electrical signal and sends the CTP plate to the position. The transportation principle is to store it in sequence according to the principle of proximity. When the storage and retrieval plate structure moves to the corresponding position through the slide rail 3, the screw rod moves with the push piece 5, pushing the CTP plate to move into the position (there is a sensor here to sense whether the CTP plate is stored, and an alarm signal is given if it is not stored normally), and the storage and retrieval plate structure returns to its original position and the push piece returns to its original position.

[0039] When the printing machine gives a plate use signal in the printing queue, the plate storage and retrieval structure receives the corresponding signal and moves to the corresponding position through the slide rail 3. At the same time, the pusher 5 moves to the other end of the plate rack 2 through the slide 6. The pusher clamps the CTP plate and takes it out. The plate storage and retrieval structure moves to the mechanical arm 4 through the slide rail 3. The mechanical arm 4 receives the electrical signal and places the taken-out CTP plate on the conveyor, which sends it to the upper plate transport rack and transports it to the printing machine.

[0040] When the CTP plate is actually clamped, since the CTP plate is in contact with the frame of the bin 1, there is friction between the CTP plate and the frame. When the plate clamp clamps the CTP plate, since the clamping force is not too large (too large a clamping force will damage the CTP plate, causing cracks on the CTP plate, affecting the use of the CTP plate), the CTP plate may slide under the influence of friction, and the CTP may fall off the plate clamp. Therefore, in a further embodiment, Figure 4-Figure 6 As shown, the push piece 5 is an L-shaped structure, and a mounting position is formed at the notch, and two plate clamps 53 are installed in the mounting position. The side wall of the mounting position of the push piece 5 is provided with an inner groove, and a side wall of one of the plate clamps 53 is provided with a protrusion that matches the inner groove. The protrusion and the inner groove are both T-shaped structures, and the protrusion is slidably installed in the inner groove. The plate clamp 53 is slidably connected to the side wall of the mounting position of the push piece 5, that is, a sliding plate clamp, and two rotating plates 51 are rotatably installed at the bottom of the two plate clamps 53. A torsion spring is provided at the connection between the sliding plate clamp and the rotating plate 51, one end of the torsion spring is fixedly connected to the rotating plate 51, and the other end is fixedly connected to the sliding plate clamp, and the torsion spring provides a rebound force to the rotating plate 51. When the rotating plate 51 rotates, under the action of the rebound force, the rotating plate 51 is restored to a state perpendicular to the plate clamp 53, as shown in FIG. Figure 4 and Figure 6 As shown, a parallelogram structure is formed between the two plate clamps 53 and the two rotating plates 51, and the four corners of the parallelogram can all rotate so that the parallelogram can be deformed, and the distance between the two plate clamps 53 can be shortened, and the other plate clamp 53 is a movable plate clamp.

[0041] The two rotating plates 51 are rotatably mounted with a moving block 54 at one end away from the pusher 5, and the moving block 54 is parallel to the plate clamp 53; the inner wall of the installation position of the pusher 5 is rotatably mounted with a gas pressure rod 52, such as Figure 6 As shown, the cylinder body of the pneumatic rod 52 is rotatably connected to the push piece 5, and a waist-shaped hole is opened at one end of the moving block 54. The telescopic end of the pneumatic rod 52 is movably installed in the waist-shaped hole. When the pneumatic rod 52 is telescopic, it can move with the moving block 54, and the moving block 54 causes the two rotating plates 51 to deflect. The movement of the moving block 54 and the movable plate clamp are synchronized and have the same movement mode. Preferably, the pneumatic rod 52 is tilted in the installation position and tilted in the direction of movement of the moving block 54.

[0042] like Figure 6 As shown in FIG. 1 , when the rotating plate 51 and the two plate clamps 53 are in a vertical state, the distance between the two plate clamps 53 is the largest. This state is the natural state when the CTP plate is not clamped. After the rotating plate 51 rotates to a vertical position on the sliding plate clamp, it will not rotate again, and the protrusion is located at the front end position of the inner groove. When the CTP plate needs to be clamped, the air pressure rod 52 contracts, and the moving block 54 moves to the inner side of the installation position, as shown in FIG. Figure 6 In the direction indicated by the middle arrow, theoretically, the moving block 54 will first slide the two plate clamps 53 inward until the protrusion of the sliding plate clamp contacts the rearmost end of the inner groove, and the sliding plate clamp stops moving. As the pneumatic rod 52 continues to contract, the moving block 54 continues to move with the movable plate clamp, and the corner of the parallelogram changes. The moving block 54 deflects the two rotating plates 51 synchronously, and the deflection direction of the two rotating plates 51 is the same as the movement direction of the moving block 54, and the distance between the two plate clamps 53 becomes smaller, so that the CTP plate can be clamped.

[0043] In this embodiment, since the pneumatic rod 52 is arranged at an angle, when the pneumatic rod 52 is extended to its longest position, the sliding plate clamp is located at the front end of the inner groove, and the inclination angle of the pneumatic rod 52 is relatively small. When the pneumatic rod 52 begins to initially contract, the pneumatic rod 52 and the moving block 54 can be regarded as being on the same line. Under the action of the torque provided by the torsion spring, the sliding plate clamp and the rotating plate 51 will not rotate easily, and the moving block 54 will move downward with the two plate clamps 53. After the protrusion moves to the bottom of the inner groove, as the pneumatic rod 52 continues to contract, the torque provided by the moving block 54 to the rotating plate 51 is greater than the torque of the spring, and the rotating plate 51 will rotate on the sliding plate clamp, thereby bringing the two plate clamps 53 close to clamp the CTP plate.

[0044] After the two plate clamps 53 clamp the CTP plate, when the pusher 5 moves the CTP plate outward, if the friction between the CTP plate and the bin 1 is large, the direction of the friction is opposite to the movement direction of the CTP plate, that is, the CTP plate will provide the two plate clamps 53 with a force opposite to its movement, such as Figure 7 In this state, the CTP plate will move outward with the two plate clamps 53 or have a tendency to move outward, and the force does not coincide with the force borne by the moving block 54. Figure 7 As shown by the middle arrow, the force will cause the rotating plate 51 to deflect, thereby increasing the clamping force between the two plate clamps 53, thereby preventing the CTP plate from falling off the plate clamps.

[0045] When the pneumatic rod 52 moves with the moving block 54, as the moving block 54 moves with the sliding plate clamp, friction will be generated between the protrusion and the inner groove. Once the friction is greater than the torque of the spring, the rotating plate 51 will rotate, causing the two plate clamps 53 to be clamped. However, since the sliding plate clamp slides in the inner groove, even if the protrusion does not slide to the bottom of the inner groove, it is separated from the front end of the inner groove. When the CTP plate clamp is transported outward, the friction generated by the frame of bin 1 on the CTP will still act on the plate clamp 53, causing the plate clamp 53 to bear a force opposite to its movement direction.

[0046] The process of the plate clamp 53 releasing the CTP plate is opposite to the clamping process, which will not be described in detail here. Example

[0047] The difference from Example 1 is that: like Figure 8 As shown, the bin 1 is a cylindrical frame structure, and a material taking channel is provided in the middle of the bin 1 coaxially with the bin 1, and the material taking channel is a cylindrical cavity structure. A support leg is fixedly installed at the bottom of the bin 1, and the support leg is fixed to the ground by bolts. A mechanical arm 4 (not shown in the figure) is placed on one side of the bin 1.

[0048] A lifting platform 15 is installed directly below the material taking channel. The lifting platform 15 is a hydraulic lifting platform or a pneumatic lifting platform, preferably a hydraulic vertical lifting (straight top) lifting platform. The bottom of the lifting platform 15 is slidably arranged on the slide rail 3, and a driving motor 8 is arranged on the slide rail 3. The driving motor 8 drives the lifting platform 15 to slide on the slide rail 3 (the arrangement of the slide rail 3, the lifting platform 15 and the driving motor 8 is the same as the connection method of the slide rail 3, the support frame 23 and the driving motor 8 in Example 1).

[0049] A supporting cylinder 14 is rotatably installed on the top section of the lifting platform 15, a motor 1 is fixedly installed on the top of the inner cavity of the supporting cylinder 14, a support column 10 is fixedly installed on the upper end surface of the supporting cylinder 14, the support column 10 is a cylindrical cavity structure, and a screw rod 2 17 is rotatably installed inside, the output end of the motor 1 is fixedly connected to the bottom of the screw rod 2 17, and the motor 1 provides power to the screw rod 2 for rotating the screw rod 2 17.

[0050] like Figure 8 and Fig.10As shown, an axially distributed sliding groove 16 is provided on the outer side of the lower end of the support column 10, and a lifting ring 11 is slidably installed on the outer side of the lower end of the support column 10. A slider is fixedly installed on the inner side wall of the lifting ring 11, and an inner ring coaxial with the lifting ring 11 is fixedly installed on the slider. The inner ring is installed inside the support column 10, and the slider is located inside the sliding groove 16, and the slider can slide up and down in the sliding groove 16. A thread matching with the second screw rod 17 is provided on the inner side wall of the inner ring. When the second screw rod 17 rotates, it can carry the inner ring and the lifting ring 11 to move up and down on the outside of the support column 10.

[0051] like Figure 8 and Fig. 9 As shown, a plate rack 2 is slidably mounted on the outer upper end of the support column 10. The plate rack 2 is a cylindrical plate-like structure and is coaxially arranged with the support column 10. A radially distributed slide groove is provided on the plate rack 2. A slide table 6 is slidably mounted in the slide groove. A push piece 5 is fixedly mounted on the side of the slide table 6 facing the outside. A plate clamp 53 is mounted on the push piece 5 (the structural design of the plate clamp 53 is the same as that of Example 1, which will not be repeated here). The bottom of the slide table 6 extends out of the slide groove, and a U-shaped frame is fixedly mounted on the protruding end. A roller 9 is rotatably mounted on the upper end of the plate rack 2 at the edge of the slide groove. The roller 9 supports the CTP plate and can assist in the clamping of the CTP plate. A plate surface 25 (not shown in the figure) is fixedly mounted on one side of the slide groove of the plate rack 2. A roller 9 and a slide bar 21 are mounted on the plate surface 25. The roller 9 is flush with the roller 9 at the edge of the slide groove.

[0052] like Figure 8 and Fig.11 As shown, a support arm 13 is rotatably mounted at the bottom of the support column 10, and the support arm 13 can be rotated outward to open. A rotating shaft is rotatably mounted at the top of the support arm 13, and the rotating shaft is rotatably connected to the U-shaped frame. Baffles are fixedly mounted at the bottom of both sides of the slideway of the plate rack 2, such as Fig.12 As shown, grooves are provided on opposite sides of the two baffles, and both ends of the rotating shaft are located in the grooves and can slide in the grooves.

[0053] An active strip 12 is installed on the outer side of the lifting ring 11. One end of the active strip 12 is rotatably connected to the outer side of the lifting ring 11, and the other end is rotatably connected to the upper end of the support arm 13. When the lifting ring 11 moves up and down, it can move one end of the active strip 12 upward or downward, so that the support arm 13 can be unfolded or collected outside. Fig.12As shown. When the lifting ring 11 moves to the uppermost end, the active strip 12 is in a horizontal state, and the support arm 13 is expanded outward to the maximum state. When the lifting ring 11 moves downward, one end of the active strip 12 moves downward with the lifting ring 11, and the support arm 13 moves inward to collect until the bottom of the sliding groove 16 of the lifting ring 11 moves, and the support arm 13 collects (or gathers) to the minimum state. At this time, the slide 6 just moves to the innermost side of the slide groove of the plate frame 2, and the CTP plate is all located on the plate frame 2 driven by the push piece 5 and the plate clamp 53.

[0054] like Fig.12 As shown, since the bottom of the support arm 13 is rotatably connected to the bottom of the support column 10, the bottom of the support arm 13 will not move on the support column 10, and the upper end of the support arm 13 is slidably connected to the baffle. When the active strip 12 carries the support arm 13 to expand outward (or close inward), the support arm 13 rotates outward (or inward) with its bottom as the center, and will carry the plate frame 2 downward (or upward) on the support column 10.

[0055] The number of the support arms 13, the slide slots of the plate rack 2 and the active strips 12 is set in multiples according to actual use requirements, and the same structures are distributed in a ring array. Fig.13 As shown, when the plate is a four-color plate, there are four support arms 13, four slide slots of the plate frame 2, and four active strips 12, and the angles between the four support arms 13, the four slide slots of the plate frame 2, and the four active strips 12 are all 90 degrees. When the plate is a two-color plate, there are two support arms 13, two slide slots of the plate frame 2, and two active strips 12, and the angle between adjacent structures of the same type is 180 degrees.

[0056] In this embodiment, taking the example that four supporting arms 13, four slide slots of the plate rack 2 and four active strips 12 are provided, the storage position 1 is equally divided into four areas.

[0057] An external gear 18 is provided on the outer side of the bearing cylinder 14, and a motor 2 is fixedly installed on the upper end of the lifting platform 15. A driving gear meshing with the external gear 18 is fixed on the output end of the motor 2. In this embodiment, the motor 2 is preferably a servo motor. The motor 2 is used to rotate the bearing cylinder 14. In this embodiment, the bearing cylinder 14 can only rotate 360 ​​degrees at most, that is, the motor 2 can only rotate one circle with the bearing cylinder 14. Since the bearing cylinder 14 is provided with electric wires and air pressure pipes, when the bearing cylinder 14 rotates one circle, the electric wires and air pressure pipes can rotate 360 ​​degrees with the bearing cylinder 14, and do not cause excessive winding of the electric wires and air pressure pipes. In this embodiment, in order to more conveniently control the rotation of the bearing cylinder 14, a gear reducer can be installed between the output end of the motor 2 and the external gear 18, and the input end of the gear reducer is connected to the output end of the motor 2, and the input end of the gear reducer is connected to the external gear 18. The gear reducer can reduce the output speed of the motor 2, and it is more convenient to control the rotation angle of the bearing cylinder 14.

[0058] When the CTP plate is not clamped, the support arm 13 is in a collecting or gathering state on the support column 10, the support arm 13 is closest to the support column 10, and the support arm 13 supports the plate rack 2, and the plate rack 2 is at the highest position on the support column 10. When the CTP plate needs to be clamped, the lifting platform 15 extends upward, and moves upward with the bearing cylinder 14 and the support column 10 until the lifting platform 15 is extended to the longest state. Then, motor 1 rotates screw rod 2 17, screw rod 2 17 moves the inner ring and lifting ring 11 upward, and the inner end of active strip 12 moves upward with lifting ring 11, while support arm 13 expands outward, plate holder 2 moves downward, and when lifting ring 11 rises to the limit position, support arm 13 expands outward to the maximum state, active strip 12 is in a horizontal position, and plate holder 2 moves downward on support column 10 to the limit position, at this time, plate holder 2 is flush with the bottom inner side of the frame of bin 1 (that is, the plane where the top of roller 9 on plate holder 2 is located is flush with the bottom inner side of the frame of bin 1), that is, it is kept on the same horizontal plane as the bottom of the CTP plate placed on bin 1.

[0059] Driven by the support arm 13, the slide 6 is at the outermost end of the slide slot of the plate rack 2. At this time, one side of the CTP plate is located between the plate clamps 53 of the push piece 5. At this time, the pneumatic rod 52 can be controlled to work so that the plate clamps 53 clamp the CTP plate.

[0060] like Fig.12As shown, after clamping the CTP plate, the screw rod 17 moves downward with the lifting ring 11, and the lifting ring 11 moves downward with one end of the active strip 12 synchronously, and then moves the support arm 13 close to the support column 10 to gather and get close, and at the same time, the plate rack 2 rises and moves upward with the CTP, so that the CTP plate is separated from the frame of the bin 1 and is suspended. Compared with horizontal clamping of the CTP plate, since the CTP plate does not contact the bin 1, there is no friction between the bin frame (i.e., the bin plate rack 24), which makes it more convenient to take the CTP plate. In the process of taking the CTP plate from the bin 1, the CTP plate moves obliquely upward, directly simulating the process of manually taking the CTP plate upward. The CTP plate will not be worn due to friction with the bin frame 1 (i.e., the bin plate rack 24) during the process of taking. When the active bar 12 brings the support arm 13 together, the CTP plates are all located directly above the plate rack 2, and the lifting platform 15 can be lowered to the initial state. The plate rack 2 with the CTP plate withdraws from the material collection channel, and the CTP plate can be taken by a mechanical arm. This is particularly suitable for the state where the CTP plate is placed vertically, and is also applicable when the CTP plate is tilted. It is necessary to ensure that the tilt angle of the push piece 5 and the plate clamp 53 is compatible with the CTP plate.

[0061] In this embodiment, the plate rack 2 can take four CTP plates (i.e., a set of four-color plates) at a time, which saves the time of taking plates and prevents confusion between sets of plates. When the mechanical arm 4 takes the CTP plate, it only needs to make the motor 2 drive the bearing cylinder 14 to rotate, so that different CTP plates rotate to the mechanical arm 4 in turn, and the CTP plate can be grabbed.

[0062] In this embodiment, Fig.13 As shown, the storage position 1 is provided with 4 areas, namely A, B, C, and D, which are used to place the four CTP plates A, B, C, and D in turn according to the instantaneous clockwise direction, and correspond to the A chute, B chute, C chute, and D chute on the plate rack 2 respectively. When the storage position 1 is used as a buffer warehouse to temporarily place the designed CTP plate, the bearing cylinder 14 is in the original state (i.e., the state of not rotating), and the A chute is directly opposite to the mechanical arm. The CTP plate uses the mechanical arm (or can be manually) to place the A plate horizontally on the A chute, and the motor 2 drives the bearing cylinder 14 to rotate 90 degrees, so that the B chute rotates to the mechanical arm, and the B plate is placed in the B chute, and the C plate and the D plate are placed in turn, and then the motor 2 is controlled to rotate in the opposite direction, and the plate rack 2 is restored to the initial state, so that the lifting platform 15 rises and drives the bearing cylinder 14 and the plate rack 2 to move upward to the limit state until the lifting platform 15 is extended to the longest.

[0063] Then, the motor 1 can rotate with the screw rod 2 17, move the lifting ring 11 upward, the active bar 12 moves the support arm 13 outward, the slide 6 moves the push piece 5 and the CTP plate outward together, and the plate frame 2 moves downward. When the support arm 13 is extended outward to the maximum state, the four CTP plates are just located in the corresponding areas of the warehouse 1, and the CTP plates are placed. During the placement process, the CTP plate is gradually placed inside the frame from the upper part of the warehouse 1, simulating the process of personnel taking it upward. Compared with the horizontal placement of the CTP plate, the CTP plate does not produce horizontal movement, and there is no friction between the CTP plate and the warehouse frame.

[0064] During the process of taking and placing the CTP plate, the CTP plate does not contact the frame of bin 1, so there is no friction, which can reduce the problem of CTP plate wear caused by friction. Since the highest position of the CTP plate is higher than the placement position in bin 1 during the process of taking and placing the CTP plate, the internal height of bin 1 should be higher than the highest position of the CTP plate to avoid collision between bin 1 and the CTP plate when placing and taking the CTP plate.

[0065] In this embodiment, in order to make the CTP plate placement more stable, a placement slot specifically used for placing the CTP plate is set at the bottom of the frame of the bin 1. The placement slots are arranged in a circular array with the axis of the bin 1 as the center. The angle between adjacent placement slots is 2 degrees (the specific angle can be designed according to actual use requirements). When placing four-color CTP plates of different sets, each set of CTP plates needs to be placed in order. It is best to place them in sequence with the edge of each area as the baseline, such as Fig.13 As shown, the arrow is the placement direction of the CTP plates, and the starting point E of each area is the baseline, which can be used to place the first set of CTP plates. The A, B, C, and D plates of the first set of CTP plates can be directly placed in the four areas A, B, C, and D of the bin 1 at one time. After placing the first set of CTP plates, the motor 2 is driven to rotate 2 degrees with the carrier cylinder 14 and the plate frame 2, and then the second set of CTP plates is placed. Each set of CTP plates can be placed in turn, and the positions of the same set of CTP plates in different placement areas are corresponding to each other. When taking the CTP plates, four plates of a set of CTP plates can be taken at one time, which is more convenient to take and more conducive to realizing automatic control. Example

[0066] The difference from Example 2 is that: A slide rail 3 is slidably installed at the bottom of the supporting cylinder 14, and a drive motor 8 is arranged on the slide rail 3. The drive motor 8 is used to move the supporting cylinder 14 along the slide rail 3 (the arrangement of the slide rail 3, the supporting cylinder 14 and the drive motor 8 can be the same as the connection method of the support frame 23, the slide rail 3 and the drive motor 8 in Example 1).

[0067] In this embodiment, the plate frame 2 is a rectangular parallelepiped structure, and a slide groove (not shown in the figure) is opened on the upper part. A motor 1 is fixedly installed on the top of the inner cavity of the bearing cylinder 14, and a support column 10 is fixedly installed on the upper end surface. The support column 10 is provided with a screw rod 2 17, a sliding groove 16, a lifting ring 11, a slide 6, a push piece 5, a roller 9, a support arm 13, and an active strip 12. The connection between the above structures can refer to Example 2. In this embodiment, the slide grooves are set to be symmetrical, which can adapt to the rectangular warehouse structure, and the slide groove of the plate frame 2 is fixedly installed with a plate 25.
