Description

Technical Field

[0001] The present invention relates to the technical field of sheet processing, and in particular to a sheet printing production line feeding device and a feeding method thereof. Background Art

[0002] In a traditional metal sheet printing production line, generally, workers carry the sheets to a conveying mechanism, and the sheets are automatically conveyed to the next process for processing. However, this feeding method has a high dependence on labor and low feeding efficiency. To solve the above problems, the existing sheet printing production line uses a manipulator with a suction cup for automatic handling and feeding. However, since the sheets are stacked before feeding and there is release paper between the sheets, the two stacked sheets and the release paper between the two sheets are easily adsorbed to each other due to surface tension. Therefore, during the process of the manipulator handling the sheets, it is easy to transfer multiple sheets to the production line at the same time, resulting in the need for rework of the sheets at the bottom, which affects the production efficiency. In addition, since there is release paper clamped between the sheets, after the top sheet is carried away, it is also necessary for workers to separate the release paper on the top of the remaining sheets from the sheets, which is highly dangerous and inefficient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to provide a sheet printing production line feeding device and a feeding method thereof to improve the feeding efficiency.

[0004] To solve the above technical problem, the technical solution adopted by the present invention is: A sheet printing production line feeding device includes a handling mechanism, a first positioning mechanism, a blowing mechanism, and an adsorption mechanism for removing release paper; the blowing mechanism, the first positioning mechanism, the adsorption mechanism, and the handling mechanism are arranged in sequence; the adsorption surface of the adsorption mechanism faces the side where the first positioning mechanism is located, and the air outlet end of the blowing mechanism is arranged opposite to the adsorption surface, so that the release paper on the first positioning mechanism is blown up and adsorbed by the adsorption mechanism; the handling mechanism includes an adsorption fixture; the adsorption fixture includes a first adsorption component, a second adsorption component, and a detection component for detecting the thickness of the adsorbed object; one second adsorption component is arranged at each end of the first adsorption component in the length direction, and the second adsorption component is rotatably connected to the first adsorption component; the detection component is arranged on the adsorption surface of the first adsorption component.

[0005] To solve the above technical problem, another technical solution adopted by the present invention is: A feeding method applied to the sheet printing production line feeding device as described above includes the following steps: S1: Position the stacked sheets. S2: Adsorb the board at the top of the stack, detect the thickness of the adsorbed board. When the thickness of the adsorbed board is greater than the preset thickness, control the adsorbed board to vibrate so that the excess board falls back into the stack; S3: After the board leaves the stack, blow up, adsorb and convey the release paper at the top of the stack in sequence for feeding; S4: The adsorbed board is transferred to the loading area.

[0006] The beneficial effects of the present invention are as follows: By setting up a blowing mechanism and an adsorption mechanism, the release paper at the top layer of the stack is separated from the board by blowing, and is adsorbed by the adsorption mechanism, so as to facilitate the adsorption of the board by the handling mechanism; and the adsorption fixture of the handling mechanism is provided with a detection component, which is used to detect whether multiple boards are adsorbed simultaneously during the process of adsorbing the board, and can control the second adsorption component and the first adsorption component to vibrate when multiple boards are adsorbed, so that the excess board is shaken off back into the stack, avoiding rework, realizing fully automated loading, and improving production efficiency.

[0009] To describe in detail the technical content, achieved objectives and effects of the present invention, the following is described in conjunction with the implementation manners and with reference to the accompanying drawings.

Preferably, the air supply mechanism 3 is a blower.

[0011] It can be understood that by arranging the air supply mechanism 3 and the adsorption mechanism 4, the release paper on the top layer of the stack is separated from the sheet by blowing air and adsorbed by the adsorption mechanism 4, so as to facilitate the handling mechanism 1 to adsorb the sheet; and the adsorption fixture 11 of the handling mechanism 1 is provided with a detection component 113, which is used to detect whether multiple sheets are adsorbed simultaneously during the process of adsorbing the sheet, and can control the second adsorption component 112 to turn upward relative to the first adsorption component 111 and vibrate in the case of multiple sheets being adsorbed, so that the redundant sheets are shaken back into the stack, avoiding rework, realizing fully automatic feeding, and improving the production efficiency.

[0012] In some embodiments, in the length direction of the adsorption fixture 11, the relative position of the second adsorption assembly 112 and the first adsorption assembly 111 is adjustable to adsorb plates of different lengths.

[0013] In some embodiments, the first adsorption assembly 111 includes a bracket 1111 and a first suction cup 1112; all the first suction cups 1112 are evenly distributed on the bracket 1111. In some embodiments, the second adsorption assembly 112 includes a second suction cup 1121, a movable beam 1122, and a linear drive member 1123; at least two second suction cups 1121 are sequentially arranged in the length direction of the movable beam 1122; one side in the width direction of the movable beam 1122 is hinged to the first adsorption assembly 111; the fixed end of the linear drive member 1123 is connected to the first adsorption assembly 111, and the movable end of the linear drive member 1123 is hinged to the movable beam 1122 to make the movable beam 1122 drive the first adsorption assembly 111 to vibrate; the movable beam 1122 is distributed along the width direction of the bracket 1111, and the fixed end of the linear drive member 1123 is connected to the bracket 1111. By controlling the linear drive member 1123 to quickly flip the movable beam 1122, the movable beam 1122 drives the first adsorption assembly 111 to vibrate, so that the excess plates are shaken back into the stack, realizing the adsorption of single plates and avoiding rework. Further, the fixed end of the linear drive member 1123 is detachably connected to the first adsorption assembly 111 through a fixing bracket 1124 to adjust the relative position of the first adsorption assembly 111 and the linear drive member 1123. An active telescopic frame 1113 is arranged in the bracket 1111, and the movable beam 1122 is slidably connected to the bracket 1111 through the active telescopic frame 1113 to adjust the relative position of the movable beam 1122 in the length direction of the bracket 1111.

Correspondingly, when the relative position of the movable beam 1122 in the length direction of the bracket 1111 changes, the position of the fixing bracket 1124 in the length direction of the bracket 1111 should also be adjusted accordingly.

[0014] In some embodiments, the adsorption mechanism 4 includes a conveyor belt 41 and a conveyor component 42 for controlling the movement of the conveyor belt 41; a plurality of evenly distributed adsorption holes 411 are formed in the conveyor belt 41; the conveyor belt 41 is wound around the outside of the conveyor component 42 and encloses a vacuum adsorption cavity with the conveyor component 42, and the vacuum adsorption cavity is communicated with the adsorption holes 411. The conveyor component 42 is arranged to move the release paper adsorbed on the surface of the conveyor belt 41 away, that is, to make the release paper leave the adsorption surface of the conveyor belt 41, so as to realize automatic blanking for the next adsorption. Specifically, the vacuum adsorption cavity is only communicated with the adsorption area of the conveyor belt 41, so that the part of the conveyor belt 41 away from the adsorption area does not have adsorption ability, which is convenient for the release paper to separate from the conveyor belt 41. It should be noted that the adsorption area is a relatively fixed area on a conveyor belt. When the conveyor component 42 drives the conveyor belt 41 to move, the adsorption area remains stationary relative to the conveyor component 42.

[0015] In some embodiments, the first positioning mechanism 2 includes a positioning table 21, two relatively arranged first positioning surfaces 22 and two relatively arranged second positioning surfaces 23; the first positioning surface 22, the second positioning surface 23 and the positioning table 21 enclose a positioning space for positioning the board; the relative positions of the first positioning surface 22 and the second positioning surface 23 and the positioning table 21 are adjustable. Through the first positioning surface 22 and the second positioning surface 23, the board is positioned in two directions on the horizontal plane, improving the positioning accuracy of the board, so that the handling mechanism 1 can accurately adsorb the board.

Specifically, the structure of the second positioning mechanism 5 is the same as that of the first positioning mechanism 2, except that the placement position of the second positioning mechanism 5 is different. The second positioning mechanism 5 is provided for loading from different directions, that is, the sheet can be positioned by either the first positioning mechanism 2 or the second positioning mechanism 5. When the loading of the sheet on the first positioning mechanism 2 or the second positioning mechanism 5 is completed, the handling mechanism 1 can grab the sheet stored in the other positioning mechanism and perform loading. The positioned sheet is transported by the handling mechanism 1 to the next process for processing to ensure the position accuracy of the sheet. Correspondingly, when the second positioning mechanism 5 is selected for loading, an air supply mechanism 3 can be respectively arranged on both sides in the thickness direction of the adsorption mechanism 4.

[0019] In some embodiments, the detection assembly 113 includes an elastic telescopic assembly 1131 and a sensing member 1132; the sensing member 1132 is connected to one side in the thickness direction of the second adsorption assembly 112 through the elastic telescopic assembly 1131, so that the sensing member 1132 moves in the thickness direction of the second adsorption assembly 112. Preferably, the sensing member 1132 is an ultrasonic sensor, and there are four elastic telescopic assemblies 1131, and the four elastic telescopic assemblies 1131 are evenly distributed along the circumference of the sensing member 1132.

When the thickness of the adsorbed plate is greater than the preset thickness, the adsorbed plate is controlled to shake so that the excess plate falls into the ash pile; S3: After the sheet leaves the stack, the release paper on the top of the stack is blown up, adsorbed and conveyed in sequence; S4: The adsorbed sheet material is transferred to the loading area.

[0022] Specifically, S1: positioning the stacked plates by a first positioning mechanism 2; S2: The adsorption fixture 11 of the transport mechanism 1 adsorbs the plate at the top of the stack, and the detection component 113 of the transport mechanism 1 detects the thickness of the adsorbed plate. When the thickness of the adsorbed plate is greater than the preset thickness, the adsorption fixture 11 is controlled to shake, so that the adsorbed plate shakes, and the excess plate falls into the ash stack; S3: When the plate leaves the stack, the air supply mechanism 3 blows up the release paper at the top of the stack, and the suction mechanism 4 sucks the blown release paper.
