DETAILED DESCRIPTION

[0026] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1The present invention provides a feeding system for a rotary printing press, including a conveying mechanism 100 for conveying a material roll A. The following stations are provided at the stopping point of the conveying mechanism 100, including:

[0028] The receiving station 200 is used to receive the transferred roll A onto the conveying mechanism 100;

[0029] The reversing station 300 is used to adjust the direction of the paper splicing part of the material roll A;

[0030] The gluing station 400 is used to glue the paper splicing portion of the material roll A;

[0031] The reel loading station 500 is used to install the material reel A onto the rotary printing press.

[0032] In this embodiment, the material roll A is transferred from the warehouse inventory to the receiving station 200 through the AGV loading equipment. The material roll A is transported to the reversing station 300 under the transmission of the conveying mechanism 100. At the reversing station 300, the paper splicing direction of the material roll A is horizontally rotated and adjusted according to the loading direction of the subsequent process. After the adjustment, the material roll A continues to be transported to the gluing station 400 for manual gluing. Finally, the glued material roll A is installed on the rotary printing press at the rolling station 500 to complete the loading operation of the material roll A.

[0033] This embodiment realizes the mechanization of loading of material roll A and reduces manpower participation, which not only improves loading efficiency, but also avoids contamination of material roll A and reduces waste of material roll. In addition, the direction of the paper splicing part of material roll A is adjusted by the reversing station 300 to better adapt to subsequent loading in different directions, thereby further improving loading efficiency.

[0034] In one embodiment, the reversing station 300 is provided with a rotating mechanism for reversing the material roll A by 180° to adjust the direction of the paper splicing portion of the material roll A.

[0035] This embodiment is configured such that the direction of the paper splicing portion of the material roll A can be horizontally rotated and adjusted according to the loading direction of the subsequent material roll A, thereby better adapting to the subsequent rolling operation.

[0036] Specifically, the rotating mechanism includes a bracket for supporting the conveying mechanism 100 and a power mechanism for driving the bracket to rotate, wherein the power mechanism can be a combination of a motor and gears or other equipment that can provide a rotational driving force.

[0037] In one embodiment, a roll lifting mechanism 401 is provided at the gluing station 400 for lifting the material roll A upward to separate it from the conveying mechanism 100 .

[0038] This embodiment is configured in this way. Since the paper splicing portion of the material roll A needs to be glued at the gluing station 400, and the paper splicing portion of the material roll A may be located at a position that is difficult to operate manually (that is, the paper splicing portion may be located at the contact position between the material roll A and the conveying mechanism 100, or may be located in the opposite direction of the manual station), the material roll A is lifted and separated from the conveying mechanism 100 by providing a roll lifting mechanism 401, and then the paper splicing portion of the material roll A is rotated to a position convenient for gluing by manually rotating the material roll A, thereby improving the convenience of manual gluing and thereby improving the loading efficiency.

[0039] In one embodiment, see Figure 2 The roll lifting mechanism 401 includes rollers arranged on both sides of the conveying mechanism 100. The rollers on both sides clamp the roll A and lift it upward to separate from the conveying mechanism 100.

[0040] For details, please refer to Figure 4 The roller is driven by the motor and the lead screw structure 4011, and is guided by the guide rail pair 4012 for movement, wherein the motor and the lead screw structure 4011 and the guide rail pair 4012 are installed on the support frame; after the material roll A is conveyed to the gluing station 400, the rollers on both sides move toward the material roll A and contact it, lifting the material roll A upward and away from the conveying mechanism 100. At this time, since the material roll A is in rolling friction contact with the material barrels on both sides, the material roll A can be easily rotated manually, thereby achieving the purpose of adjusting the position of the paper connecting part of the material roll A, thereby improving the convenience of manual gluing.

[0041] In another embodiment, see Figure 3 The roll lifting mechanism 401 may also include a clamping arm provided on one side of the conveying mechanism 100 , which clamps the two ends of the roll A and lifts it upward to separate it from the conveying mechanism 100 .

[0042] Specifically, since the center of the material roll A has a through hole that can be inserted into, the clamping arm is controlled to extend from one end or both ends of the material roll A into the through hole and lift the material roll A upward. During the process, the clamping arm and the material roll A also maintain rolling friction contact. Then, the material roll A can be easily rotated manually, thereby achieving the purpose of adjusting the position of the paper splicing part of the material roll A, thereby improving the convenience of manual gluing.

[0043] In one embodiment, the roll-up station 500 includes two rotary printing machines 502 disposed at the ends of the conveying mechanism 100 , and a transport mechanism 501 capable of reciprocatingly transporting the material roll A is disposed between the two rotary printing machines 502 .

[0044] This embodiment is configured in such a way that alternating non-stop loading can be achieved through the configuration of two rotary printing machines 502, which greatly improves the efficiency of feeding the material roll A, thereby improving the subsequent production efficiency. Specifically, after the material roll A is glued at the gluing station 400, the material roll A is transported to the rotary printing machine 502 on the corresponding side through the conveying mechanism 501 according to the required loading position, thereby completing the loading operation.

[0045] Specifically, the transport mechanism 501 drives a section of the plate chain line of the conveying mechanism 100 located at the roll-up station 500 to move toward the loading installation position of the corresponding side rotary printing machine 502, so as to convey the material roll A to the rotary printing machines 502 on both sides respectively.

[0046] Specifically, the transport mechanism 501 can be a device with a linear transport function, such as a combination of a horizontal frame and a linear guide rail.

[0047] In one embodiment, a detection mechanism 402 is further provided at the gluing station 400 for detecting the diameter of the roll A. This configuration is provided to control the distance of the roll-lifting mechanism 401 in advance, thereby effectively lifting the roll A. This configuration ensures that the structures in the roll-lifting mechanism 401 that contact the roll A maintain synchronization, thereby improving the stability of the roll A in lifting.

[0048] In one embodiment, a discharge station 600 is further included for collecting the remaining rolls discharged from the loading station 500. In this embodiment, the used roll A is removed from the rotary printing press 502 and returned to the transport mechanism 501. The transport mechanism 501 then transports the roll A to the discharge station 600 for centralized collection.

[0049] In one embodiment, a roll-out station 700 is further included for collecting and transferring the remaining rolls removed from the loading station 500. This arrangement allows for greater adaptability of the entire device, as some rolls A may not be completely consumed during use. The unused rolls A can be transferred outward through the roll-out station 700 and stored in a silo for subsequent use.

[0050] In one embodiment, the conveying mechanism 100 is a plate chain conveyor line, and the plate chain on the plate chain conveyor line is in a "V" shape.

[0051] Specifically, the conveying mechanism 100 is composed of multiple independently working plate chains, and each workstation uses a single-section plate chain system, which is convenient for independent maintenance and disperses the conveying pressure, thereby increasing the service life of the conveying mechanism 100.

[0052] Among them, the plate chain on the plate chain conveyor line is arranged in a "V" shape, which can better support the material roll A and limit the material roll A, thereby preventing the material roll A from slipping and falling out of the conveying mechanism 100 during the conveying process.

[0053] It should be noted that, when the material roll A is reversed, the plate chain conveyor line corresponding to the reversing station 300 described above rotates independently to achieve the purpose of reversing the material roll A.

[0054] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indications will also change accordingly.

[0055] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
