[0023] The present invention will be further described below with reference to the drawings and embodiments.
[0024] See figure 1 As shown, a device that contributes to the energy-saving operation of a cardboard production line includes an elevating and stacking mechanism 10, which is provided with a stacking and conveying table 1 with a lifting movement. The stacking and conveying table 1 is provided with an exit end and used with The entrance end of the cardboard production line connection is characterized in that it also includes an auxiliary lifting paper feeding mechanism 20. The auxiliary lifting paper feeding mechanism 20 is arranged next to the exit end of the lifting stacking mechanism 10. When the cardboard stacking height changes, the auxiliary lifting feeding paper The mechanism 20 is raised to a suitable height and receives the paper piles sent by the lifting and stacking mechanism 10 in time, which is beneficial for the lifting and stacking mechanism 10 to rise to the initial receiving height in time, ensuring constant speed operation of the cardboard production line and reducing energy consumption.
[0025] The auxiliary lifting paper feeding mechanism 20 includes a paper delivery and conveying table 3 and an auxiliary lifting driver 4 for driving the paper collecting and conveying table 3 to run up and down. The delivery and delivery station 3 is a one-way delivery and delivery platform. When the delivery conveyor table 3 and the stack conveyor table 1 descend to the lowest position, both of them are level with the same side L, see figure 2 Shown.
[0026] The lifting and stacking mechanism 10 includes the stacking conveying table 1 and a main lifting driver 2 for driving the stacking conveying table 1 to run up and down.
[0027] In order to improve the accuracy of control, the lifting and stacking mechanism 10 and the auxiliary lifting and feeding mechanism 20 are preferably driven by servo motors.
[0028] Combine Figure 4 As shown, the delivery and delivery platform 3 is preferably a two-way delivery and delivery platform. The two-way paper delivery and conveying table includes a conveying belt 32 and a conveying roller 31 that are staggered. The conveying direction of the conveying belt 32 and the conveying roller 31 is perpendicular, and the conveying belt 32 is also connected with a jacking mechanism (not shown in the figure) . Under normal conditions, the top surface of the conveyor belt 32 is lower than the top surface of the conveyor roller 31, the driving motor of the conveyor roller 31 is started, and the cardboard placed on the conveyor roller 31 moves in the direction of arrow A. When it is necessary to control the movement of the cardboard on the delivery conveyor 3 in the direction of arrow B, control the conveyor belt 32 to lift up so that the cardboard is placed on the conveyor belt 32, start the drive motor of the conveyor belt 32, and then control the cardboard Run in the direction of arrow B. In other words, when the delivery conveyor 3 is a two-way delivery conveyor, the cardboard can be output in the vertical and horizontal directions, and the storage of the cardboard can be more standardized.
[0029] A control method of a device that helps the energy-saving operation of a cardboard production line. When the cardboard stacking height is about to be reduced, the auxiliary lifting paper feeding mechanism 20 and the lifting paper stacking mechanism 10 are simultaneously raised to the initial paper receiving height and follow the lifting The stacking mechanism 10 is slowly lowered, or the auxiliary lifting and feeding mechanism 20 is controlled to rise to a reasonable height until the cardboard on the lifting and stacking mechanism 10 is stacked, and the auxiliary lifting and feeding mechanism 20 is level with the top of the lifting and stacking mechanism 10. The stacking conveying table 1 conveys the stacked cardboard to the auxiliary lifting and feeding mechanism 20, and then the lifting and stacking mechanism 10 immediately rises to the height of the initial receiving paper to continue receiving the paper.
[0030] After the auxiliary lifting paper feeding mechanism 20 receives the cardboard on the stacking conveying platform 1, it moves down to a low position and sends out the cardboard on it.
[0031] Or, after the auxiliary lifting paper feeding mechanism 20 receives the cardboard on the stacking conveying table 1, it controls the cardboard on it to move a certain displacement, so that the auxiliary lifting paper feeding mechanism 20 vacates a certain space and simultaneously follows the lifting stacking mechanism 10 Move, or control the auxiliary lifting paper feeding mechanism 20 to rise to a reasonable height until the cardboard on the lifting paper stacking mechanism 10 is completed, the auxiliary lifting paper feeding mechanism 20 is level with the top of the lifting paper stacking mechanism 10, and the paper stacking conveyor 1 is controlled The stacked cardboard is transported to the hole position of the auxiliary lifting paper feeding mechanism 20, and the cycle is repeated until the auxiliary lifting paper feeding mechanism 20 does not have enough space to place the cardboard, the auxiliary lifting paper feeding mechanism 20 descends and moves to a low position. The cardboard on it is sent out, and at the same time, the lifting and stacking mechanism 10 immediately rises to the height of the initial paper receiving to continue receiving paper.
[0032] Preferably, the auxiliary lifting and feeding mechanism 20 has output in two directions, vertical and horizontal.
[0033] Its working principle is: combine Figure 5 As shown, when the control circuit predicts that the current specifications of the cardboard cannot be filled with the stacking conveying table and need to be converted to other specifications of cardboard, the auxiliary lifting and feeding mechanism 20 and the lifting and stacking mechanism 10 are simultaneously raised to the initial receiving paper. And follow the lifting and stacking mechanism 10 to slowly lower until the cardboard P1 on the lifting and stacking mechanism 10 is stacked. The auxiliary lifting and feeding mechanism 20 is level with the top of the lifting and stacking mechanism 10, and the stacking conveyor 1 is controlled to be stacked The good cardboard P1 is conveyed to the auxiliary lifting and feeding mechanism 20 along the direction of arrow C, and then the lifting and stacking mechanism 10 immediately rises to the height of the initial paper receiving to continue receiving paper.
[0034] Because the size of the delivery conveyor 3 is suitable for large-area cardboard stacking, and when the cardboard P1 is a small area specification and the cardboard specification of the next batch of orders is also a small area, when the cardboard P1 enters the delivery conveyor 3, the delivery The paper conveying table 3 controls the cardboard P1 on it to move a certain displacement (see Image 6 As shown by the arrow in the middle D), the paper delivery conveyor 3 makes a certain space, and at the same time, the paper delivery conveyor 3 and the lifting and stacking mechanism 10 are raised again to the height of the initial paper receiving and follow the lifting and stacking mechanism 10 Slowly descend until the cardboard P2 on the lifting and stacking mechanism 10 is stacked, the auxiliary lifting and feeding mechanism 20 is level with the top of the lifting and stacking mechanism 10, and the stacking conveying platform 1 is controlled to move the stacked cardboard P2 along Figure 7 It is conveyed to the auxiliary lifting paper feeding mechanism 20 in the direction of the middle C arrow, and then the lifting and stacking paper mechanism 10 rises to the height of the initial paper receiving to continue receiving paper (see Figure 8 As shown by the arrow in the middle E), at the same time, the delivery conveyor 3 takes two stacks of cardboard P1 and P2 down to the lower position (see Figure 8 As shown by the arrow in the middle F), and send out the cardboard P1 and P2 at the same time. Of course, the above operation can be suitable for continuous short orders. If it is not a continuous short order, the delivery conveyor 3 can output the cardboard P1 line and then wait for work.
[0035] In addition, sometimes because the original cardboard is relatively wide, and the cardboard produced by the order requires a small area specification, the cardboard production line can output more than two specifications of cardboard at the same time, and it can also be received in the above manner.
