Description

Technical Field

[0001] The invention relates to the field of CTP plate material forming, and in particular to a product forming stabilizing device used for CTP plate material production. Background Art

[0002] CTP (Computer-to-Plate) plate is a technology used for printing plate making. It is a technical carrier that directly makes plates through computer data, replacing the traditional film plate making process. It can achieve high-precision image reproduction, and the resolution can usually reach above 2400dpi. It is suitable for fine printing. It mainly includes thermal type, silver salt type, photopolymerization type and processing-free type. Among them, the manufacturing process of thermal CTP is the most common.

[0003] The manufacturing process of thermal CTP plates mainly includes three steps: substrate pretreatment, coating liquid preparation and final plate manufacturing and processing. When the CTP plates are finally manufactured, considering that the CTP plates include photosensitive coatings, these materials are sensitive to light, moisture, temperature and physical damage. Therefore, they must be moisture-proof, light-proof, dust-proof, and mechanically damaged. We need to package the CTP plates.

[0004] At present, the packaging is done by manually stacking the CTP plates in portions, then covering them with film, and finally packaging them with plastic tape, but this method has a low degree of automation. The substrate of conventional CTP plates is a rigid substrate (such as aluminum plate), that is, the conventional type is not flexible, but for special needs, the market has also developed limited flexible plate variants that take into account CTP platemaking efficiency and slight bending ability. Generally, polyester film (PET) can be used instead of aluminum plate. At this time, the flexibility of CTP plates is easy to bend during transportation, which leads to irreversible damage to the plates and also restricts the difficulty of automated stacking.

DETAILED DESCRIPTION

[0020] Next, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0021] A product forming stabilization device for CTP plate production comprises a frame 1, on which a conveyor belt 2 for conveying CTP plates (hereinafter referred to as plates) is arranged. The plates to be packaged fall onto the conveyor belt 2 from the upper process to the lower process, and then fall onto a transfer box 3 under the conveyance of the conveyor belt. The frame 1 is also provided with a counter 4 for counting the plates traveling on the conveyor belt 2. When the counted number reaches a preset value, it is considered that the number of plates currently falling onto the transfer box 3 reaches a packaging amount, and then the conveyor belt 2 stops transmitting the plates, and the plates currently in the transfer box 3 are transferred and packaged.

[0022] As described in the background technology, the polyester-based CTP plate has a certain flexibility. When the plate moves to the end of the conveyor belt, the end that first extends outside the conveyor belt 2 will bend downward under its own weight. As the length of its extension increases, the end sags more, and the damage to the plate is obvious. At the same time, when half of the plate is suspended outside the conveyor belt, the center of gravity of the plate will no longer be on the conveyor belt, and the plate may even flip over. At present, by increasing the conveying rate of the conveyor belt, the plate has a higher speed when leaving the conveyor belt. The plate will detach from the conveyor belt under inertia and fall forward on the transfer box 3 to prevent the plate from flipping over. However, at this time, the friction between the plate initially falling on the conveyor belt and the conveyor belt is severe, which damages the plate. At the same time, the collision between the plates falling on the transfer box 3 under inertia may also cause damage, and the randomness of the falling position makes it impossible to regularize the plate falling on the transfer box 3, which needs to be further regularized.

[0023] In order to solve the problem of neatly stacking the plates on the transfer box 3, the present embodiment adopts the following technical solution: a guide 5 is provided under the conveyor belt 2, and the guide 5 is controlled to extend and receive the plate that is about to leave the conveyor belt. When the end of the plate moves outside the conveyor belt, the guide 5 is controlled to move forward synchronously to receive the end of the plate. In the process of the plate gradually leaving the conveyor belt, the guide 5 also moves forward synchronously until the plate completely leaves the conveyor belt and falls completely on the guide 5. Due to the existence of the guide 5, the plate does not fall directly on the transfer box 3, but first falls on the guide 5. The guide is close to the conveyor belt, so that the front end of the plate only undergoes a small deformation in the process of falling into the guide, and at this time the conveyor belt can also use a conventional speed to transport the plate to protect the plate.

[0024] The guide 5 acts as a transfer to transport the plate to the top of the transfer box 3. Then the guide 5 retreats and the plate falls directly on the transfer box 3. To prevent the plate from retreating with the guide 5, the frame 1 is connected with a mounting rod 6 located below the conveyor belt 2 and above the guide 5. The mounting rod 6 is connected with a blocking member 7, and the bottom of the blocking member 7 is in contact with the top surface of the guide 5. When the guide 5 retreats, based on the adhesion characteristics of the blocking member 7 and the guide, the blocking member 7 will prevent the plate from retreating with the guide and then falling to the transfer box 3 below.

[0025] When conveying the plate material, the distance between the guide member 5 and the transfer box 3 needs to be the thickness of the number of plates stacked in one-time packaging on the transfer box 3. In order to eliminate the random position of the plates when falling on the transfer box 3, this embodiment adopts the following technical solution: one end of the guide member 5 is rotatably connected to a mobile frame 8, and the mobile frame 8 is controlled to reciprocate to receive and release the plate material. The other end serves as a guiding end, and a sliding protrusion 501 is provided on the side of the guide member 5; a guide plate 9 is also fixedly connected to the frame body 1, and an upper sliding groove 901 is provided on the guide plate 9. A sliding groove 301 is provided on the side wall of the box 3, and the upper sliding groove 901 and the two ends of the lower sliding groove 301 are connected to form an annular slide. The width of the lower sliding groove 301 is set according to the thickness of the plate material required to be stacked in the transfer box 3; the annular slide is provided with a rotating plate 10 on the side close to the conveyor belt, and one end of the rotating plate 10 passes through the guide plate 9 through a rotating shaft, and the other end contacts the oblique groove wall of the lower sliding groove 301. A torsion spring 11 is provided on the rotating shaft. The function of the torsion spring is to generate an elastic force that always presses the rotating plate 10 against the oblique groove wall of the lower sliding groove 301.

[0026] When the guide member 5 conveys the plate material forward, the rotating plate 10 is pressed against the oblique groove wall of the sliding groove 301 under the elastic force of the torsion spring, and the sliding protrusion 501 on the side of the guide member 5 first passes over the rotating plate 10 and then enters the upper sliding groove 901 until the plate material is sent to the top of the transfer box 3; then the guiding end of the guide member 5 falls into the connected sliding groove 301, at this time, the guide member 5 is in an inclined state, and the plate material falls into the transfer box 3 along with the guiding end, and then the sliding protrusion 501 retreats along the sliding groove 301, and the plate material is gradually flattened in the transfer box 3 during the retreat process; when the sliding protrusion 501 moves along the oblique groove wall of the lower sliding groove 301, the rotating plate 10 is pushed open and then reset, waiting for the next cycle, and after the rotating plate 10 is reset, the rotating plate 10 that was pushed open is reset and pressed against the oblique groove wall of the sliding groove 301 under the elastic force of the torsion spring.

[0027] The blocking member 7 is rotatably connected to the mounting rod 6, and a second torsion spring 12 is provided between the mounting rod 6 and the blocking member 7. Its function is that when the guide member 5 is in an inclined state during movement, the rotatable blocking member 7 has rotational freedom and can always maintain tight pressure on the guide member 5 under the action of the second torsion spring 12.

[0028] During the retraction of the guide member 5, the guide end of the guide member 5 will press down on the plate material already stacked in the transfer box 3 under its own weight. On the one hand, in order to prevent the friction generated by the contact with the plate material during the retraction process from causing the stacked plate material to be displaced, or even being taken out of the transfer box 3, and on the other hand, in order to avoid the friction between the guide end and the plate material causing irreversible damage to the plate material, the present invention adopts an air suspension method so that the guide end of the guide member 5 is suspended above the plate material without direct contact. The scheme is as follows: a flow channel is provided in the guide member 5, and an air port 502 is provided on the side of the guide end facing the plate material, and the flow channel is connected to the air pump 13. The airflow input by the air pump blows from the air port 502 of the plate material to the plate material already stacked in the transfer box 3, and the reaction force causes the guide end of the guide member 5 to be suspended above the plate material for a distance, so as to achieve the purpose of the guide end not being in direct contact with the plate material during retraction.

[0029] The transfer box 3 is close to the conveyor belt and is used as a transfer and transportation for plates. After reaching the guaranteed quantity, the transfer box 3 moves down and transfers the plates stacked inside to the packaging tooling. The frame 1 is provided with an electric slide rail 14, and the side wall of the transfer box 3 is provided with an integrated connecting arm 15. The connecting arm 15 is connected to an integrated straight rod 16, and the straight rod 16 passes through the slider 17 of the electric slide rail 14. In addition, the end of the straight rod 16 is connected to a first block 18, and the block 18 is pressed on the slider 17. When the transfer box 3 is in a high position to receive plates, the first block 18 is pressed on the slider 17 by its own weight to achieve high-position stillness. After reaching the target quantity, the electric slide rail 14 is activated, and the slider 17 descends to bring the transfer box 3 to a low position.

[0030] The packaging tool is located below the transfer box 3. When the transfer box 3 drops to a low position, the stacked plates therein can be automatically transferred to the packaging tool. The specific scheme is as follows: the side wall of the transfer box 3 is provided with a slide groove, and the bottom plate 19 is slidably arranged at the slide groove. The side wall of the transfer box 3 is connected to a first screw 20, and a screw sleeve 21 is arranged on the first screw 20, and the screw sleeve 21 is connected to both sides of the bottom plate 19; the end of the screw sleeve 21 is connected to a first gear 22, and the first gear 22 rotates synchronously with the first screw 20; a guide column 23 is also connected to the connecting arm 15, and a second block 24 is connected to the top of the guide column 23. An extension piece 25 is slidably provided on the guide column 23, and the extension piece 25 is fixedly connected to the slider 17 of the electric slide rail 14. A spring 26 is also sleeved on the guide column 23, and the two ends of the spring 26 are distributed in contact with the extension piece 25 and the connecting arm 15, and the extension piece 25 is connected to a first rack 27, and the first rack 27 is meshed with the first gear 22.

[0031] The operation of the electric slide rail 14 to make the slider 17 descend is divided into two stages: the first stage is the stage of the transfer box 3 descending, during which the slider 17 descends, and the transfer box 3 descends together with the slider 17 by its own weight. At this time, the first rack 27 and the first gear 22 do not mesh and transmit until the transfer box 3 is pressed on the packaging tool below; the second stage is the stage of the bottom plate 19 being pulled out, when the transfer box 3 is pressed on the packaging tool below and is in a stationary state, the electric slide rail 14 is operated to make the slider 17 continue to descend, at this time, the first rack 27 and the first gear 22 are not meshed and transmitted. The block 18 is disengaged from the slider 17, and the extension piece 25 descends with the slider 17. While compressing the first spring 26, the first rack 27 descends and rotates the first screw 20 through the meshing action with the first gear 22. The rotating first screw 20 converts the rotation into movement of the screw sleeve 21 through the cooperation with the screw sleeve 21, and then the bottom plate 19 is linked to slide outward, and the plate in the transfer box 3 is blocked in the transfer box 3 by the obstruction of the frame, and falls on the packaging tooling under its own weight, thus completing the transfer of the stacked plates.

[0032] After being transferred to the packaging tool, the transfer box 3 is reset, and the packaging tool can be removed for independent packaging operations. This embodiment uses the following technical solutions to enable the packaging tool to automatically move to the bottom of the transfer box 3 when it descends, and can automatically move outward when the transfer box 3 is reset: the packaging tool is slidably set on the frame 1 through the support feet 28, and the frame 1 is also provided with a second screw 29. The packaging tool is connected to the second screw 29 through a second screw sleeve 30, and the second screw 29 is also provided with a second gear 31. The slider 17 of the electric slide rail 14 is also connected to the second rack 32 through a connecting rod, and the second rack 32 is meshed with the second gear 31. In the first stage of the transfer box 3's descent, the meshing transmission of the second rack 32 and the second gear 31 causes the second screw 29 to rotate, and the second screw sleeve 30 drives the packaging tool to move directly below the transfer box 3. When the first stage is over, the transfer box 3 just falls on the packaging tool, and the second rack 32 is disengaged from the second gear 31. In the second stage, the second rack 32 continues to move downward, but the packaging tool is stationary at its original position.

[0033] The packaging tooling includes a storage box 33, which is provided with a sink groove on its symmetrical side wall, and a base 34 that can be taken separately is provided at the sink groove, and the distance between the base 34 and the end of the storage box 33 exceeds the stacking height of the single-packaging plates. When the transfer box 3 is pressed down on the top of the storage box 33, and the bottom plate 19 is slid outward and pulled out, the plates in the transfer box 3 fall onto the base 34 in the storage box 33, and because the stacking height of the single-packaging plates is less than the storage height of the storage box 33, the bottom plate 19 can be retracted into the transfer box 3 when the transfer box 3 is reset to the initial state. Based on the independent setting of the base 34, the base 34 can be directly taken away together with the plates stacked thereon.

[0034] The packaging tool is used to package the stacked plates carried by it. In the initial state, the packaging bag is pre-placed on the bottom bracket 34, and the edge after flattening is located outside the storage box 33. The packaging bag is moved together with the packaging tool to the bottom of the transfer box 3. In order to stabilize the position of the packaging bag, this embodiment positions the packaging bag by gluing. Specifically: a plurality of gluing wheels 35 are provided at the bottom of the storage box 33, and the bottom bracket 34 is provided with a position avoidance groove 341. The top of the gluing wheel 35 is exposed in the position avoidance groove 341. When the packaging bag needs to be placed, the adhesive on the adhesive wheel 35 can adhere to the packaging bag to position the packaging bag. After the packaging tool is removed, the packaging bag can be directly wrapped with the plate. The adhesive is weak enough to meet the positioning of the packaging bag. Finally, the packaging bag is removed together with the bottom bracket 34, and the packaging bag can be detached from the adhesive wheel 35 without damage.

[0035] In order to reduce the workload of applying adhesive glue on the adhesive wheel 35 each time, the present embodiment is implemented by the following scheme: a glue-dispensing wheel 36 is rotatably provided in the storage box 33, and a tape is wound on the glue-dispensing wheel 36, and the free end of the tape is wound on the adhesive wheel 35, and the glue-dispensing wheel 36 is connected to the output shaft of the stepper motor 37. The function of the glue-dispensing wheel 36 is to expose the adhesive surface of the tape wound on the glue-dispensing wheel 36 in the reverse direction, and the adhesiveness of the adhesive part of the bottom support 34 exposed by the glue-dispensing wheel 36 decreases after each packaging, and before placing the packaging bag each time, the stepper motor 37 drives the glue-dispensing wheel 36 to rotate through a certain angle to expose the new adhesive part of the tape.

[0036] The adhesive tape of the present invention has low viscosity, and is intended to not damage the packaging bag when it is separated from the packaging bag. However, at this time, it is necessary to increase the surface area of ​​the adhesive wheel 36 exposed to the bottom bracket 34 to increase the adhesion area. However, this will cause the stacked plates to be suspended when they fall on the bottom bracket 34, and the bottom plate and the adhesive wheel 36 are in line contact. Strong pressure may damage the plate. Therefore, in this embodiment, the entire adhesive wheel assembly is set on an elastic member to achieve the purpose of protecting the plate. Specifically: the storage box 33 is provided with a slide groove 331, the adhesive wheel 36 is rotatably set on the sliding frame 38, and the adhesive wheel 35 is rotatably set on the fixed length rod 39, the fixed length rod 39 is fixedly connected to the sliding frame 38, and the sliding frame 38 is slidably matched with the slide groove 331; a guide column 40 is provided in the slide groove 331, the guide column 40 passes through the sliding frame 38, and the guide column 40 is provided with a second spring 41, and the second spring 41 is compressed between the sliding frame 38 and the bottom of the slide groove 331.

[0037] The adhesive wheel 35, the adhesive release wheel 36, the stepper motor 37, the sliding frame 38 and the fixed-length rod 39 constitute a lifting unit. Before the stacked plates fall into the storage box 33, the lifting unit is at the highest position under the action of the second spring 41. When it is at the highest position, the sliding frame 38 is partially at the top position in the slide groove 331 and is stationary, and the top surface of the adhesive wheel 35 is exposed on the bottom support 34; when the stacked plates fall into the storage box 33, the plates press the lifting unit downward, and the lifting unit compresses the second spring 41, so that the adhesive wheel 35 is no longer exposed on the bottom support 34, and the plates are flat on the bottom support 34, so as to protect the plates.

[0038] As mentioned above, one end of the guide member 5 is rotatably connected to the movable frame 8, and the movable frame 8 is controlled to reciprocate to cooperate with the conveyor belt to receive and release the plate. This embodiment is realized through the linkage of a stable mechanical structure, and the scheme is as follows: cranks 43 are connected at both ends of the rotating shaft 42 that moves with the conveyor belt, the crank 43 is rotatably connected to one end of the first connecting rod 44, the other end of the first connecting rod 44 is rotatably connected to the second connecting rod 45, one end of the second connecting rod 45 is rotatably connected to the third connecting rod 46, the third connecting rod 46 is fixedly connected to the frame body 1, the other end of the second connecting rod 45 is rotatably connected to one end of the fourth connecting rod 47, the other end of the fourth connecting rod 47 is rotatably connected to the movable frame 8, the frame body 1 is also connected to a slide rod 48, and the movable frame 8 is slidably set on the slide rod 48.

[0039] The crank 43, the first connecting rod 44, the second connecting rod 45, the third connecting rod 46, and the fourth connecting rod 47 constitute a connecting rod mechanism. The input of the connecting rod mechanism is the rotation of the crank 43 driven by the rotating shaft 42, and the output is converted into a linear displacement of the movable frame 8 through the transmission output of the connecting rod mechanism. By designing the length of the connecting rod mechanism, the movable frame 8 can be controlled to move back and forth to cooperate with the conveyor belt to receive and release the plate.

[0040] The present invention uses a guide member to ensure that the front end of the plate undergoes only a small deformation in the process of falling into the guide member, and the plate can be transmitted at a conventional speed to protect the plate; the blocking member 7 is fitted to the top surface of the guide member 5 to prevent the plate from retreating when the guide member 5 retreats, and then falls to the transfer box 3 below; the guide member 5 is guided by an annular slide formed by the guide plate 9 and the side wall of the transfer box 3, and a flow channel is provided in the guide member 5. The air flow blows from the air port 502 of the plate to the stacked plates in the transfer box 3, and the reaction force causes the guide end of the guide member 5 to float a distance above the plate, so that the guide end does not directly contact the plate when retreating, thereby preventing the plate from being brought back and causing damage to the plate.

[0041] When the transfer box 3 is transferred to the packaging tool, the transfer box 3 descends and the packaging tool moves to the bottom thereof. The plate in the transfer box 3 can be transferred to the packaging tool through the two-stage descent of the slider; the packaging tool can pack the plate, and the packaging bag can be positioned in the storage box 33 through the adhesive wheel 35. When the plate falls into the storage box 33, the lifting unit is pressed down, and the lifting unit compresses the second spring 41, so that the adhesive wheel 35 is no longer exposed on the bottom support 34, and the plate is flat on the bottom support 34 to protect the plate; the packaging tool can automatically change the adhesive position. Before placing the packaging bag each time, the stepper motor 37 drives the adhesive wheel 36 to rotate a certain angle to expose the new adhesive position of the tape.

[0042] The crank 43, the first connecting rod 44, the second connecting rod 45, the third connecting rod 46 and the fourth connecting rod 47 form a connecting rod mechanism. By designing the length of the connecting rod mechanism, the movable frame 8 can be controlled to move back and forth to cooperate with the conveyor belt to receive and release the plate.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
