Description

Technical Field

[0001] The utility model relates to the field of slitting machines, in particular to a paper receiving mechanism of a slitting machine. Background Art

[0002] The paper collection lift is an auxiliary equipment commonly used in printing, binding, packaging and other industries. Its main function is to collect and organize paper or other printed materials in a certain order and height for subsequent processing or storage and transportation.

[0003] After the slitting machine cuts the roll paper into paper of unit specifications, it is sent to the paper collection lifting platform for unified collection via a conveyor belt. When the paper pile on the paper collection lifting platform reaches a certain height, the equipment stops, and the paper pile on the paper collection lifting platform is placed in a three-dimensional warehouse for storage or directly packaged for transportation. Whether it is storage or transportation, it is necessary to know the height of the paper pile, but the traditional method of measuring the height of the paper pile is to measure it manually. Manual measurement is inefficient and has certain errors, resulting in packaging waste and increased costs. The height error will cause the paper pile to be unable to be completely placed in the three-dimensional warehouse or cause space waste. Summary of the invention

[0004] The utility model aims at the shortcomings of the prior art and provides a paper stack height detection device for a slitting machine, which improves measurement efficiency, avoids packaging waste and improves space utilization.

[0005] To solve the above technical problems, the utility model is solved by the following technical solutions: a paper collection mechanism of a slitting machine, characterized in that it includes a paper collection lifting platform, a height detection device and a control system; the paper collection lifting platform is connected to a power member that drives it to rise and fall on a frame; the height detection device includes a distance meter and an in-place sensor; the distance meter is arranged above the paper collection lifting platform to measure the height of the paper pile on the paper collection lifting platform; the in-place sensor is arranged at an in-place station, and the in-place sensor is used to detect the paper collection lifting platform at the in-place station; the control system includes a display, and the power member, the distance meter and the in-place sensor are all connected to the control system; when the paper collection lifting platform descends to the in-place station, the distance meter and the in-place sensor send information to the control system, the paper collection lifting platform stops rising and falling, and the display shows the measured height.

[0006] The distance meter and the in-place sensor of the utility model are both fixedly arranged, so the vertical distance between the two is a fixed value. When the paper collection lifting platform reaches the in-place station, the in-place sensor detects the paper collection lifting platform, and the control system controls the equipment to stop feeding and the paper collection lifting platform to stop moving. The control system calculates: the vertical distance between the distance meter and the in-place sensor - the real-time distance of the distance meter = the height of the paper pile. The display shows the calculation result of the control system. There is no need to manually measure the height of the paper pile, which improves work efficiency and has high accuracy. Subsequent operators can fill the stereoscopic warehouse according to the height of the paper pile, thereby improving the space utilization rate of the stereoscopic warehouse, and can also select packaging with effective specifications according to the height of the paper pile to avoid packaging waste.

[0007] Preferably, a paper support is provided on the paper receiving lifting platform, and a paper stopper is provided on one side of the paper support, and the paper stopper is arranged opposite to the discharge end of the slitting machine, and the paper stopper is arranged vertically on the paper support. The paper stopper can ensure that the paper sent out after being cut by the slitting machine falls on the paper support, and the vertical paper stopper can ensure the verticality and stability of the whole paper pile.

[0008] On the basis of having a paper support, a weight sensor is provided between the paper support and the lifting platform, the weight sensor is electrically connected to the control system, and the weight sensor measures the weight of the paper pile. The weight sensor is connected to a display through the control system, and the weight of the paper pile is displayed on the display, and the corresponding load-bearing outer packaging or stereoscopic warehouse is selected according to the weight of the paper pile.

[0009] Preferably, the in-position sensor is a proximity switch, and the in-position sensor is arranged on one side of the paper collection lifting platform. When the proximity switch detects the paper collection lifting platform, the control system controls the paper collection lifting platform to stop moving, ensuring that the initial fixed value remains unchanged and the accuracy of the paper pile height value is ensured.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, a paper collection mechanism of a slitting machine includes a paper collection lifting platform 1, a height detection device and a control system; the paper collection lifting platform 1 is connected to a power member that drives it to rise and fall on a frame, and the feeding end of the paper collection lifting platform 1 is connected to the discharging end of the slitting machine 7. The roll paper is cut into unit-sized paper by the slitting device of the slitting machine 7, and is transmitted to the paper collection lifting platform 1 through the conveyor belt on the slitting machine 7. The paper collection lifting platform 1 descends with the height of the paper stack until the paper collection lifting platform 1 descends to the in-position station, and finally the paper stack on the paper collection lifting platform forms a paper pile. The height detection device includes a distance meter 2 and an in-position sensor 3. The distance meter 2 is arranged above the paper collection lifting platform 1. The measuring direction of the distance meter 2 is perpendicular to the top surface of the paper pile 8, and measures the height of the paper pile 8 from the distance meter 2 to the paper collection lifting platform 1. The in-place sensor 3 is arranged at the in-place position. The in-place sensor 3 is fixedly arranged at the in-place position. The in-place sensor 3 is used to detect the paper collection lifting platform 1 at the in-place position. The in-place sensor 3 is fixedly arranged. The in-place sensor 3 can be a photoelectric eye or a proximity switch. When the in-place sensor 3 is a proximity switch, the in-place sensor 3 is arranged on one side of the paper collection lifting platform 1. The control system includes a display. The power part, the distance meter 2, and the in-place sensor 3 are all connected to the control system. When the paper collection lifting platform 1 descends to the in-place position, the distance meter 2 and the in-place sensor 3 send information to the control system, the paper collection lifting platform 1 stops lifting, and the display shows the measured height. After measuring the height of the paper pile 8, a mark can be attached to the paper pile 8 by connecting a printer or manually, which is convenient for subsequent management.

[0018] Working principle: the distance meter 2 and the in-position sensor 3 are fixedly arranged, and the relative positions of the in-position sensor 3 and the distance meter 2 do not change, so the vertical distance between the two is a fixed value. The paper delivery lifting platform 1 descends as the height of the paper pile 8 increases until the paper delivery lifting platform 1 reaches the in-position position. Figure 3As shown, the in-place sensor 3 detects the paper collection lifting platform 1 and sends a signal to the control system. The control system controls the slitting machine 7 and the paper collection lifting platform 1 to stop working at the same time. The distance meter 2 measures the vertical distance of the top layer of paper in the paper pile 8 to obtain the distance between the distance meter 2 and the top layer of paper in the paper pile 8 (referred to as the measured distance). The arithmetic operation is the vertical distance between the distance meter 2 and the in-place sensor 3 - the measured distance = the height of the paper pile 8. The distance meter sends the measured distance information to the control system. The control system displays the height of the paper pile 8 on the display through the above arithmetic operation for easy reading. Automatically measuring and calculating the height of the paper pile can reduce the error of manual measurement and improve efficiency. Accurate values ​​can effectively improve the space utilization rate of the stereoscopic warehouse. Operators can also use packaging materials of corresponding specifications according to the values ​​of the paper pile 8 to avoid packaging waste.

[0019] like Figure 2 As shown, as a preferred embodiment, a paper support board 4 is provided on the paper receiving lifting platform 1, and the paper support board 4 is placed on the upper surface of the paper receiving lifting platform 1. The paper pile 8 is received by the paper support board 4, and the paper pile 8 is placed on the paper support board 4. The height of the paper support board 4 is input into the controller, so that the arithmetic operation of the height of the paper pile 8 is the vertical distance between the distance meter 2 and the in-position sensor 3-the measured distance-the height of the paper support board 4=the height of the paper pile 8. The paper support board 4 has a paper stopper 5 on one side, and the paper stopper 5 is arranged opposite to the discharge end of the slitting machine 7, and the paper stopper 5 is vertically arranged on the paper support board 4. There are many ways to set the paper stopper 5. The paper stopper 5 is set on the paper receiving lifting platform 1. The paper stopper 5 can be long enough and set upright to meet the height of the paper pile 8, or the paper stopper 5 is fixed on the frame, and the paper receiving plane of the paper support board 4 (i.e., the uppermost layer of the paper pile 8) always intersects with the paper stopper plane of the paper stopper 5. The paper stopper 5 ensures that the paper can stably fall on the paper support board 4, and the paper stopper 5 can ensure the verticality and stability of the paper pile 8 as a whole.

[0020] As a preference, Figure 4 As shown, a weight sensor 6 is provided between the paper support 4 and the lifting platform, and the weight sensor 6 is connected to the control system, and the weight sensor 6 measures the weight of the paper pile 8. In the initial state, the weight sensor 6 measures the weight of the paper support 4 and the paper baffle 5 (i.e., the initial weight). As the paper is stacked, the weight gradually increases until the paper collection lifting platform reaches the in-place station, and the slitting machine 7 stops feeding. At this time, the weight detected by the weight sensor 6 is the final weight, and the final weight minus the initial weight = the weight of the paper pile 8. The control system performs arithmetic operations on the weight of the paper pile 8, so that the display shows the weight value of the paper pile 8, and selects the corresponding weighing packaging specifications according to the weight of the paper pile 8 to avoid packaging damage caused by excessive weight. At the same time, the corresponding weight value can be marked on the measured paper pile 8 to facilitate subsequent overall management. Among them, the operator can also calculate the number of papers in the paper pile 8 according to the weight and height of the paper pile 8 to improve the accuracy of the data.
