Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and in particular to a fully automatic supply device and supply method for a paper delivery partition of a printing press. Background Art

[0002] At present, in the paper collection technology of sheet-fed printing presses and the paper collection technology after in-line slitting of web printing presses, for highly smooth paper (such as glass cardboard, coated paper, etc.), the heat dissipation of the paper stack after printing is slow. If the ink on the surface of the printed sheet is not completely cured, it is easy to cause the adjacent printed sheets to stick together; for the cold stamping process, the edges of the cold stamping position of the printed sheet after production are prone to glue overflow, which is also easy to cause the adjacent printed sheets to stick together; in addition, when the temperature and humidity in the production workshop are too high, it is also easy to cause the printed sheets to stick together.

[0003] In actual production, to effectively alleviate the problem of sheet sticking, the printed surface is often evenly sprayed with powder (usually flour, cornstarch, or other plant starches) before delivery. This creates an isolation layer between the sheets, facilitates air flow between the sheets, and accelerates surface drying. However, improper control of the amount of powder sprayed can also cause quality issues. For example, too little can still cause sheet sticking, while too much can reduce the wear resistance of the ink layer. Powder spraying also affects the gloss of printed products, the adhesion strength of laminated products, and the quality of subsequent hot stamping processes. Furthermore, long-term production will undoubtedly increase production costs.

[0004] In addition, there is also a method of manually placing partitions above the paper stack every certain number of printed sheets during the paper collection process to separate it from the subsequent printed sheets, thereby controlling the number of printed sheets stacked to prevent the paper stack from sticking together under heavy pressure. The partition structure and placement method are described in the utility model patent with announcement number: CN207267748 U. The general working process is as follows: a partition slightly larger than the pallet needs to be placed on the pallet of the main receiving paperboard in advance, and the system accurately adjusts the paper delivery angle and height according to the sheet format and hardness of the paper to be received, and controls the chain to lift the main receiving paperboard to the set position close to the paper feeding tooth row or under the conveyor belt, and the partition on the pallet receives the stack of printed sheets; the system controls the chain to descend at a matching speed according to the speed at which the paper feeding tooth row or conveyor belt delivers the printed sheets, that is, the printing speed, to ensure that the upper surface of the paper stack on the pallet maintains a dynamically stable height difference from the paper feeding tooth row or conveyor belt; when the partition receives a certain number of printed sheets (depending on the degree of adhesion caused by the ink-receiving or cold-ironing area of the printing plate, usually 500 sheets), it is necessary to manually lift the transverse shift component according to the system prompt and insert it close to the paper feeding tooth row or under the conveyor belt. The main receiving paperboard is controlled to be lowered appropriately, and then two right-angle plates are placed on the partitions at the four corners of the paper stack (four right-angle plates are required when the printed sheets are large) and partitions are placed on the right-angle plates; the main receiving paperboard is then controlled to rise to the appropriate position where the newly placed partitions are close to the bottom of the transverse shift assembly, and the transverse shift assembly is manually pulled out to make the temporarily received paper stack fall naturally to the newly placed partitions due to gravity, and the newly placed partitions continue to receive the paper; this cycle repeats until the main receiving paperboard is lowered to a certain height close to the ground (or the paper stack is stacked to a set height or number of sheets), the system controls the main receiving paperboard to be lowered to the ground, and the forklift takes out the pallet, partitions and paper stack fork on the main receiving paperboard, and then places an empty pallet and partitions on the main receiving paperboard, and repeats the above paper receiving steps. Regarding the method of placing partitions at intervals during paper collection and stacking to reduce sheet adhesion, since the two right-angle plates that support the partitions are placed independently, it is easy to cause unstable stacking of paper between the upper and lower partitions; and each time a partition is placed, two or even four right-angle plates must be manually placed first, which is inefficient; in addition, auxiliary accessories such as partitions and right-angle plates are numerous and stored and stacked in a scattered manner, which takes up a lot of workshop space.

[0005] Therefore, in order to effectively reduce the problem of printed sheet adhesion, and at the same time to avoid the problems existing in the above-mentioned prior art and facilitate actual production applications, it is urgently necessary to provide a convenient and efficient printing press paper collection partition fully automatic supply device and supply method.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] It should be noted that when a component is referred to as being “mounted on,” “fixed on,” or “disposed on” another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being “connected to” another component, it may be directly connected to the other component or there may be an intermediate component.

[0032] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0033] See also Figure 1 and Figure 2The paper collecting partition 1 is automatically fed to the paper collecting section 100 of the printing press by the present invention. ...

[0034] The paper collection partition 1 includes a base plate 11, at least one pair of legs 12 disposed on the base plate 11, and a control assembly 4 for controlling the folding or unfolding state of the legs 12. The legs 12 are hinged to the base plate 11, and the pair of legs 12 are connected by a crossbar 115. The control assembly 4 connects the two relatively folded legs 12. By setting the legs 12 to be foldable, the paper collection partition 1 can be easily stored to reduce its occupied space. In combination with the crossbar 115, the control assembly 4 can control the folding or unfolding state of at least one pair of legs 12, thereby reducing the cost of the paper collection partition 1 and simplifying its operation steps. Furthermore, a torsion spring 14 is provided at the hinge between the legs 12 and the leg slots 112 to facilitate the automatic unfolding of the legs 12, saving time and effort.

[0035] Specifically, there are four plate legs 12, and they are placed at the four corners of the base plate 11 to achieve optimal stability and avoid shaking or tipping over during the paper collection and stacking process of multiple paper collection partitions 1. The size of the base plate 11 is larger than the size of the paper, specifically the size of the rectangle formed when the plate legs 12 are unfolded is larger than the size of the paper, so as to avoid the unfolding of the plate legs 12 affecting the paper collection during the paper collection process. More specifically, the base plate 11 is a lightweight rigid material with a certain thickness, preferably plastic, lightweight alloy or wood board, so that it has a certain bearing capacity and the advantage of being light in weight, so as to reduce the load on the storage device 2. The plate legs 12 are made of iron material, which makes it have high strength, which is conducive to the stacking of multiple paper collection partitions 1 during the paper collection process and plays a good supporting role.

[0036] Preferably, a foldable hinge 13 is provided between the board leg 12 and the base plate 11, the board leg 12 has a hinge groove 121 for accommodating the foldable hinge 13, the base plate 11 has a board leg groove 112 for accommodating the board leg 12 and a cross bar groove 113 for accommodating the cross bar 115, one end of the foldable hinge 13 is connected to the board leg 12 and is located in the hinge groove 121, the other end of the foldable hinge 13 is connected to the base plate 11 and is located in the board leg groove 112, when the board leg 12 is folded, the foldable hinge 13 is received in the hinge groove 121, and the board leg 12 is placed in the board leg groove 112, so that the surface of the base plate 11 is flat, which is conducive to the stacking of the paper collection partition 1, when the board leg 12 is unfolded, the foldable hinge 13 plays the role of supporting the board leg 12, and is a triangular support, so that the board leg 12 is more stable when unfolded, which is convenient for the stacking of multiple unfolded paper collection partitions 1 during the paper collection process.

[0037] Specifically, the bottom end of the board leg 12 (i.e., the hinged end of the board leg 12 and the base plate 11) has a "7"-shaped recess 122, so that when the board leg 12 is unfolded, a part of the board leg 12 is in contact with the base plate 11, so that the base plate 11 plays the role of supporting the board leg 12, thereby reducing the load at the hinge and increasing the load-bearing capacity of the board leg 12.

[0038] like Figure 2 As shown, a base magnet 114 is provided on the base plate 11, and a leg magnet 123 is provided at the bottom of the leg 12. The base magnet 114 and the leg magnet 123 are arranged opposite each other. Specifically, the leg magnet 123 is arranged in a "7"-shaped recess 122. When the leg 12 is unfolded, the leg magnet 123 and the base magnet 114 are attracted to each other, further stabilizing the leg 12. Furthermore, when multiple unfolded paper collection partitions 1 are stacked during paper collection, the base magnet 114 and the leg 12 of the lower paper collection partition 1 are attracted to each other, stabilizing the upper and lower paper collection partitions 1, thereby preventing the stacked paper collection partitions 1 from tipping over. Moreover, the base magnet 114 is larger than the leg magnet 123, so that when the upper paper collection partition 1 is stacked on the leg 12 of the lower paper collection partition 1, the combination of the base magnet 114 and the leg 12 will not be blocked.

[0039] Please also refer to Figure 3 、 Figure 4 and Figure 5The control assembly 4 includes a two-way locking assembly 41 and a knob 42. The two-way locking assembly 41 includes a symmetrically arranged lock 411, a spring 412, a lock hook 413, and a control member 414. The lock hook 413 is connected to the lock 411, the spring sleeve 415 is provided on the lock 411, the control member 414 is connected to the lock hook 413, and the knob 42 is connected to the control member 414. When the knob 42 is rotated, the lock hook 413 is controlled to pull back, thereby retracting the lock 411. After the plate legs 12 are unfolded, the lock 411 can be automatically reset by the spring 412, which is convenient to use. Moreover, the two-way locking assembly 41 can control the unfolding or locking of the two pairs of plate legs 12, so that the entire paper collection partition 1 only needs to be controlled by a two-way locking assembly 41 to control the unfolding or locking of all the plate legs 12, which greatly facilitates the operation of the staff. Specifically, one side of the base plate 11 has a recessed hole 116 for accommodating the knob 42 to prevent the knob 42 from being accidentally touched during operation.

[0040] The two-way locking assembly 41 also includes a retaining frame (not shown in the figure) and a spring sleeve 415. The retaining frame is arranged at the connection between the lock hook 413 and the control member 414 to prevent the connection between the lock hook 413 and the control member 414 from loosening or separating when the control member 414 rotates. The spring 412 is located in the spring sleeve 415, and the lock buckle 411 and the lock hook 413 pass through the spring sleeve 415. The spring sleeve 415 plays a role in positioning the spring 412, and when the lock buckle 411 and the lock hook 413 retract, the spring is compressed.

[0041] Specifically, one end of each of the lock hooks 413 has a hook-shaped portion 4131 for hooking the lock buckle 411, and the other end of the lock hook 413 has a limiting boss 4132. The two lock hooks 413 are arranged at a distance, and the control member 414 is placed in the middle of the distance between the two lock hooks 413. Both sides of the control member 414 have wing-shaped portions 4141, and the wing-shaped portions 4141 extend out of the limiting bosses 4132 of the two lock hooks 413. In the initial state, the wing-shaped portions 4141 are arranged horizontally (such as Figure 4 As shown), when the control member 414 is rotated, the wing-shaped portion 4141 drives the two limiting bosses 4132 to move toward each other, thereby retracting the lock 411 hooked by the two lock hooks 413 (as shown). Figure 5 As shown, when the knob 42 is loosened, the control member 414 is free of force, and the spring 412 releases the elastic force, causing the lock 411 to return to its original position, making operation extremely simple. The two limiting bosses 4132 enable the control member 414 to control the lock hook 413 to move backward when rotating forward or reverse, facilitating operation.

[0042] like Figure 2As shown, the lock catch 411 extends into the plate leg groove 112, and the top of the plate leg 12 is provided with a lock hole 124 for the lock catch 411 to be inserted. When the plate leg 12 is folded, the lock catch 411 is inserted into the lock hole 124 to lock the plate leg 12, preventing the plate leg 12 from automatically unfolding during transportation or handling, thereby saving space. When the knob 42 controls the lock catch 411 to retract, the lock catch 411 separates from the lock hole 124, and the plate leg 12 can be unfolded. Furthermore, the lock catch 411 has a guide bevel or guide arc portion. When the paper on the paper collection partition 1 is removed and the plate leg 12 is folded into the plate leg groove 112, the guide bevel or guide arc portion automatically retracts the lock catch 411 and automatically inserts the lock catch 411 into the lock hole 124.

[0043] Please continue reading Figure 1 The storage device 2 includes two partition conveying mechanisms 21, and the partition conveying mechanism 21 includes a conveyor belt 211, a stepper motor (not shown in the figure), a driving wheel 212 and a driven wheel 213. The stepper motor is connected to the driving wheel 212, and the conveyor belt 211 connects the driving wheel 212 and the driven wheel 213. A number of card holders 2111 are evenly distributed on the conveyor belt 211. The card holders 2111 on the two conveyor belts 211 are arranged opposite to each other, and the two conveying mechanisms 21 operate synchronously. During use, the paper collection partition 1 is placed on the card tray 2111. The two symmetrical card trays 2111 on the two conveyor belts 211 hold up the paper collection partition 1. When the conveyor belt 211 is controlled by the stepper motor, the paper collection partition 1 on the card tray 2111 is transported downward. After the paper collection partition 1 is transported to the conveying device 3, another paper collection partition 1 can be inserted into the top card tray 2111 to achieve storage and intermittent transportation of the paper collection partition 1, meeting the intermittent paper collection requirements of the printing press. The card tray 2111 is made of a non-ferrous, lightweight, rigid material. While supporting the paper collection partition 1, it can also reduce the load on the conveyor belt 211 and the stepper motor. It can also avoid the substrate magnet 114 and the card tray 2111 being attracted to each other when the card tray 2111 is made of ferrous material, which affects the transportation of the paper collection partition 1.

[0044] In one embodiment, the conveying device 3 includes a lifting assembly 31 and a transverse shifting assembly 32. The transverse shifting assembly 32 is mounted on the lifting assembly 31 and is located directly below the drop point of the delivery separator 1. This allows the delivery separator 1 to be directly delivered to the delivery section 100 of the printing press without requiring any positional adjustments when placed on the transverse shifting assembly 32. During production, when the delivery separator 1 needs to be delivered to the delivery section 100 of the printing press, the lifting assembly 31 is raised, the transverse shifting assembly 32 lifts the bottommost delivery separator 1 on the conveyor belt 211, and the transverse shifting assembly 32 then delivers the delivery separator 1 to the delivery section 100 of the printing press.

[0045] In another embodiment, the conveying device 3 includes a transverse shifting assembly 32 positioned directly below the drop point of the delivery separator 1. This allows the delivery separator 1, when placed on the transverse shifting assembly 32, to be directly delivered to the delivery section 100 of the printing press without requiring any positional adjustments. When the delivery separator 1 needs to be delivered to the delivery section 100 of the printing press, the conveyor belt 211 rotates, causing the lowest delivery separator 1 to fall due to its own weight, landing on the transverse shifting assembly 32. The transverse shifting assembly 32 then delivers the delivery separator 1 to the delivery section 100 of the printing press.

[0046] Both of the above-mentioned conveying devices 3 can realize the conveyance of the paper collection partition 1. Among them, the lifting assembly 31 and the transverse movement assembly 32 are both existing technologies and will not be described in detail here. In this embodiment, the lifting assembly 31 and the transverse movement assembly 32 are preferably a screw slider structure. Of course, the transverse movement assembly 32 can also be directly moved by a robot.

[0047] Furthermore, the fully automatic supply device for the paper collection partition of the printing press also includes a frame 5 and a chassis 6, the frame 5 is arranged on the chassis 6, the storage device 2 and the conveying device 3 are both arranged on the frame 5, and the frame 5 also has a partition placement port (not shown in the figure) to facilitate the addition of the paper collection partition 1 to the conveyor belt 211.

[0048] Based on the above-mentioned printing press paper delivery partition automatic supply device, the present invention also provides a corresponding printing press paper delivery partition automatic supply device paper delivery partition supply method, including the following steps (such as Figure 6 shown):

[0049] S1, the paper collection partition is placed on the card tray of the storage device and transported downward in sequence;

[0050] S2. When the lowest paper delivery partition is transported to the set position, the transport device receives the paper delivery partition and transports it to the paper delivery part of the printing press.

[0051] Specifically, the lifting assembly controls the traverse assembly to rise, so that it lifts the lowest paper delivery partition on the conveyor belt, and then the traverse assembly transports the paper delivery partition to the paper delivery section of the printing press. When the traverse assembly moves into the hole groove on the surface of the tray and makes the paper delivery partition contact with the tray surface and fall onto it, the traverse assembly and the lifting assembly return to their original position.

[0052] After the conveying device transports the paper collection partition to the paper collection part, the conveyor belt operates to fill the paper collection partition at the bottom of the storage mechanism, and at the same time puts a new paper collection partition at the top of the storage device through the partition placement port, and repeats this cycle.

[0053] S3. The legs of the paper delivery partition are unfolded and propped up by turning a knob to separate the stacked paper in the paper delivery section of the printing press. Specifically, after the paper delivery partition is placed on the tray, the legs are unfolded by controlling the knob to firmly connect the base leg magnets with the base plate magnets. When the paper delivery partition has received a certain number of sheets (usually about 500 sheets), a new paper delivery partition is delivered to the paper delivery section by the conveyor device to temporarily collect the paper. The new paper delivery partition is then placed on the four legs of the previous paper delivery partition. The legs are then unfolded to firmly connect the base plate magnets of the new paper delivery partition with the leg magnets of the lower paper delivery partition. This process is repeated.

[0054] When the paper collection height of the paper collection partition reaches a certain height, the paper collection partition on the pallet is removed by a forklift, and then the above paper collection steps are repeated.

[0055] Before step S1 , the printing press adjusts the paper drop angle and height according to the sheet size and paper stiffness, and raises the main paper delivery board on which the tray is placed close to the conveying device.

[0056] After step S3, the process also includes, after the paper on the paper collection partition carrying the paper is removed, pushing the board legs from the outside to the inside, retracting the board legs in turn and locking them in the board leg grooves, and then placing the paper collection partition back in the storage mechanism for the next production application.

[0057] In summary, the present invention provides a fully automatic supply device and supply method for paper collection partitions of a printing press, wherein the fully automatic supply device for paper collection partitions of the printing press plays the function of temporarily storing and conveying paper collection partitions at intervals through a storage device during the production process, and cooperates with the conveying device to automatically convey the paper collection partitions to the paper collection part of the printing press as needed, so as to realize the rapid placement of the paper collection partitions above the paper stack, which can ensure the stable stacking of the paper stacks between the upper and lower paper collection partitions, and can also realize the reasonable storage and access of the paper collection partitions. Compared with the existing method that requires manual placement of partitions by staff, the present invention has the characteristics of high degree of automation, high production efficiency, time and labor saving, etc.

[0058] Furthermore, when collecting paper, the legs of the paper collecting partition can be folded to support the previous paper collecting partition, so that the paper stacks can be stacked at intervals. After use, the legs can be folded and stored, so that the paper collecting partition takes up less space and is easy to store, so that it can be repeatedly placed in the storage device for the next paper collecting operation.

[0059] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the claims attached to the present invention.
