Description

Technical Field

[0001] The utility model relates to a post-printing mechanical device, in particular to a paper picker for quantitatively picking paper from a paper stack. Background Art

[0002] A paper picker is a post-printing mechanical device that automatically and quantitatively picks paper from a paper stack and reduces the labor intensity of workers. In the existing paper picker technology, generally, when the paper pick-up roller rotates and approaches the paper stack, the upper and lower layers of the paper stack are separated for picking. However, since the paper pick-up roller is circular, when it contacts the paper stack, it is often difficult to accurately control the separation height of the paper stack, that is, the number of sheets of paper picked each time cannot be accurately controlled, and errors are inevitably present. Therefore, it cannot adapt to the application scenarios that require high-precision quantitative paper picking. Moreover, since the bottom of the paper stack contacts the tray, the paper pick-up roller at the end of the paper picking operation cannot smoothly enter the paper stack, and automatic paper picking cannot be completed. It is necessary to manually assist in lifting the end of the paper stack so that the paper pick-up roller can smoothly contact and enter the bottom of the paper stack. This often poses a risk of collision between people and the moving paper picking table or paper pick-up roller, presenting a certain safety hazard. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a high-precision quantitative paper picker that can reliably ensure the accuracy of the number of sheets of paper picked from the paper stack each time and improve the operation safety of the device.

[0004] The present utility model is implemented through the following technical solutions:

[0005] A high-precision quantitative paper picker, comprising a paper picking table and a paper clamping manipulator arranged above the paper picking table. The paper picking table and the paper clamping manipulator can be horizontally slidably arranged on a lifting cross beam and are independently pushed by respective power components. The lifting cross beam moves up and down. A paper pick-up roller is provided at the front end of the paper picking table. It is characterized in that: a sheet inserting and clamping manipulator is arranged at a side position in front of the paper pick-up roller, and a detection sensor for sheet inserting detection is arranged below the sheet inserting and clamping manipulator. The sheet inserting and clamping manipulator and the detection sensor are movably arranged relative to the paper picking table. During the paper picking operation, a sheet insert that can be clamped by the sheet inserting and clamping manipulator is pre-inserted into the paper stack to be picked, and the sheet insert divides the paper stack into upper and lower parts in a set number of sheets or height.

[0006] The sheet inserting and clamping manipulator can move left and right and up and down relative to the paper picking table. The sheet inserting and clamping manipulator can be movably installed on a sliding frame in the up and down direction. The up and down movement of the sheet inserting and clamping manipulator is pushed by a lifting cylinder. The sliding frame can be movably installed on a mounting plate in the left and right direction. The left and right movement of the sliding frame is pushed by a telescopic cylinder. The mounting plate is fixedly connected to the lifting cross beam.

[0007] The detection sensor is a contact type limit switch. The detection sensor can be movably installed on the mounting plate in the left and right direction. The left and right movement of the detection sensor is pushed by a sensor telescopic cylinder.

[0008] The paper pick-up machine of the above technical solution is provided with an insert clamping manipulator on the basis of the existing paper pick-up machine. Before the paper pick-up operation, inserts that can be clamped by the insert clamping manipulator are pre-inserted into the paper stack, and the inserts divide the paper stack into upper and lower parts by a set number of sheets or height. In the process of each paper pick-up operation of the paper pick-up machine, first, the detection sensor is used to detect the position of the insert, and then information is sent to control the clamping manipulator to grab the insert and lift the insert, so that the end of the upper paper stack separated by the insert is lifted as a whole, leaving a gap. Then, the paper pick-up table and the paper pick-up roller move towards the paper stack, and the paper pick-up roller enters the bottom of the upper paper stack from the gap position to perform the paper pick-up action; since the setting of the insert has ensured the accurate number of sheets in each paper stack in advance, the accuracy of the number of sheets picked up by the paper pick-up machine each time is also ensured. In addition, since inserts are also provided between the bottom of the paper stack and the tray, by grabbing the insert with the clamping manipulator and lifting the insert, the paper pick-up roller can smoothly contact and enter the bottom of the paper stack, thus avoiding the need for manual assistance to lift the end of the paper stack and preventing the danger of collision between people and the moving paper pick-up table or paper pick-up roller, thereby improving the safety of equipment operation.

[0017] As Figures 1 - 3As shown in the figure, the high-precision quantitative paper picker of the present utility model includes a paper picking table 1 and a paper clamping manipulator 2 arranged above the paper picking table 1. The paper picking table 1 is horizontally slidably arranged on a lifting cross beam 6 and is pushed by a paper picking table motor. The paper clamping manipulator 2 is horizontally slidably arranged on the lifting cross beam 6 and is pushed by a paper clamping manipulator motor. The lifting cross beam 6 moves up and down on a frame 4 and is pushed by a hydraulic cylinder or a lead screw. A paper picking roller 3 driven by a paper picking motor is arranged at the front end of the paper picking table 1. A chip clamping and picking manipulator 5 is arranged at a side position in front of the paper picking roller 3. The chip clamping and picking manipulator 5 has an upper clamping jaw 51 and a lower clamping jaw 52 pushed by a clamping cylinder 53. The chip clamping and picking manipulator 5 can move left and right and up and down relative to the paper picking table 1. The chip clamping and picking manipulator 5 is vertically movably installed on a sliding frame 11. The vertical movement of the chip clamping and picking manipulator 5 is pushed by a lifting cylinder 12. The lifting cylinder 12 is fixedly installed on the top of the sliding frame 11. The sliding frame 11 is horizontally movably installed on a mounting plate 10. The horizontal movement of the sliding frame 11 is pushed by a telescopic cylinder 9. The telescopic cylinder 9 is fixedly installed on the mounting plate 10. The mounting plate 10 is fixedly connected to the lifting cross beam 6 through a support plate. A detection sensor 7 for detecting the chip B is arranged below the chip clamping and picking manipulator 5. The detection sensor 7 is a contact type limit switch. The detection sensor 7 is horizontally movably installed on the mounting plate 10. The horizontal movement of the detection sensor 7 is pushed by a sensor telescopic cylinder 8. The sensor telescopic cylinder 8 is fixedly installed on the mounting plate 10. See Figure 3 , when picking paper, a chip B that can be clamped by the chip clamping and picking manipulator 5 is pre-inserted in the outer direction of the paper stack A picked by the paper picker. The chip B divides the paper stack A into upper and lower parts by a set number of sheets or height. The insertion of the chip can accurately count the number of sheets in the paper stack manually or by machine, or accurately measure the height of the paper, and then place the chip between the upper and lower layers of the paper stack.

[0018] The present utility model works as follows: The initial working state is shown in Figure 3 . At this time, the paper picking roller is close to the upper part of the paper stack. Then, the paper picking table moves down. The detection sensor will touch the uppermost chip. The detection sensor sends information. After the paper picking table continues to move down a certain height, the clamping manipulator extends forward to grab the chip ( Figure 4 shown state). Subsequently, the lifting cylinder acts to drive the chip to lift. Thus, the end of the upper paper stack separated by the chip is lifted as a whole, leaving a gap ( Figure 5 shown state). Then, the paper picking table and the paper picking roller move towards the paper stack. The paper picking roller enters the bottom of the upper paper stack from the gap position to perform the paper picking action. The front end of the upper paper stack enters the paper clamping manipulator and is clamped and fixed by the paper clamping manipulator ( Figure 6 shown state). Then, the paper picking table and the paper picking roller continue to move forward, while the paper clamping manipulator remains stationary until the entire upper paper stack falls onto the paper picking table ( Figure 7In the above state), the first paper picking operation of the paper picker is completed. After the upper paper stack is taken away, the paper picker returns to Figure 3 the state shown in the figure, and the next paper picking operation is performed. In the above paper picking process, since the setting of the inserted piece has ensured the accurate number of sheets in each paper stack in advance, the accuracy of the number of sheets picked by the paper picker each time is also ensured.
