Description

Technical Field

[0001] The invention relates to a paper collecting device of a die cutting machine, in particular to a paper collecting device capable of switching between high stacking and counting stacking. Background Art

[0002] There are two main types of post-press die-cutting equipment purchased and used by China's printing and packaging factories. One is the low-efficiency manual die-cutting machine, which is unsafe and widely used in small-scale workshop-type factories; the second is the fully automatic die-cutting machine, which is efficient, safe, and expensive, and is mainly purchased and used by large-scale printing and packaging factories. With the increase in labor costs and the country's increasing attention to safety issues, efficient and safe automated equipment is becoming more and more popular among users. Automatic die-cutting machines will replace manual die-cutting machines, which will also become a development trend and have great significance for the survival and development of printing and packaging factories.

[0003] The automatic die-cutting machine uses different paper collection devices for different paper products. For general paper products, a high-pile paper collection device is used. However, for corrugated paper, the high-pile paper collection device cannot meet the paper collection requirements, so a counting stacking paper collection device is usually used. Therefore, different die-cutters are required to operate different papers, which is bound to cause waste of equipment. Therefore, how to achieve both high-pile and counting stacking on a die-cutting machine has become a technical problem that needs to be solved at present. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a paper collection device with switchable high stacking and counting stacking.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A paper receiving device capable of switching between high stacking and counting stacking comprises a high stacking paper receiving section, the high stacking paper receiving section comprises a main paper receiving platform that can be raised and lowered, the device further comprises a fence-type paper receiving platform for realizing paper receiving in a counting stacking manner, the fence-type paper receiving platform is detachably mounted on the main paper receiving platform and is raised and lowered together with the main paper receiving platform; conveyor belts are mounted on both sides of each fence of the fence-type paper receiving platform, and the fence-type paper receiving platform travels up and down between the conveyor belts.

[0007] Preferably, the device further comprises a retractable auxiliary paper receiving platform for receiving paperboards delivered from the previous process.

[0008] Preferably, the highest point of the fence-type paper receiving platform is located at the bottom of the retractable auxiliary paper receiving platform.

[0009] Preferably, the auxiliary paper receiving platform receives the cardboard sent from the previous process until the fence-type paper receiving platform rises to the bottom of the auxiliary paper receiving platform; the auxiliary paper receiving platform retracts, and the paper pile collected on the platform falls on the paper receiving fence of the fence-type paper receiving platform, and the fence paper receiving platform continues to receive paper until a preset height or quantity; the fence-type paper receiving platform descends and passes through the conveyor belt, and the paper pile is placed on the conveyor belt during the descent, and the conveyor belt is activated to transport the paper pile out of the machine; the fence-type paper receiving platform rises to the bottom of the auxiliary paper receiving platform and waits for the arrival of the next pile of paper; at the same time, during the descent, when the top surface of the paper pile is lower than the extension height of the auxiliary paper receiving platform, the auxiliary paper receiving platform extends to receive the paper.

[0010] Preferably, the paper receiving device further comprises a controller, and linkage control is adopted between the start switch of the conveyor belt and the controller of the paper receiving device. When the start switch of the conveyor belt is started, the controller enters a counting and stacking paper receiving mode.

[0011] Preferably, the paper receiving device further comprises an operation screen, which is used to input the quantity or height of the paper pile and matches the height or quantity that can be received by the auxiliary paper receiving station.

[0012] Preferably, the auxiliary paper receiving platform and the fence-type paper receiving platform are equipped with photoelectric detectors for determining the maximum height of the paper receiving pile.

[0013] When the photoelectric detector detects that the height of the delivery paper pile reaches the maximum absolute height, the paper pile will be automatically sent out as a stack regardless of whether the set count value is reached.

[0014] Preferably, the fence-type paper receiving platform is provided with four installation corners, and each installation corner is fixed to the main paper receiving platform plate by screws.

[0015] Preferably, after the device moves out of the fence-type paper receiving platform and the belt conveyor, the start switch is in the off state, and the machine enters the high-pile paper receiving mode, in which the paper pile can be moved out of the machine from two directions.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1) Reduced costs. Through the paper collection device that can switch between high-pile and counting-pile, two paper collection methods can be realized on one die-cutter, avoiding the waste of multiple devices, thereby greatly reducing the production cost for users. At the same time, for a die-cutter with only a high-pile paper collection part, only a fence-type paper receiving table is needed to realize seamless switching between high-pile paper collection and counting-pile paper collection;

[0018] 2) Easy to operate. To count and stack paper, you only need to install the fence-type paper receiving table on the main paper receiving table by screwing;

[0019] 3) It has the effect of protecting the paper. By using the fence to shuttle up and down between the conveyor belts, the paper falls smoothly on the conveyor belt and is output by the conveyor belt, avoiding the friction damage to the paper caused by the original roller method;

[0020] 4) High degree of intelligence: through the linkage control between the start switch of the conveyor belt and the controller of the paper collection device, the intelligent switching of the paper collection mode is realized, which greatly improves the intelligence level of the machine;

[0021] 5) High safety: a photoelectric detector for judging the maximum height of the paper pile is installed on the paper collection platform, thus avoiding the potential safety hazards caused by excessively high paper piles;

[0022] 6) The paper collection effect is better. By setting up a retractable auxiliary paper collection platform, the paper collection efficiency is further improved. When the paper pile is full, the auxiliary paper collection platform extends out to receive the paper during the descent and ascent process, and the machine does not need to stop and wait.

[0031] Figure 1 The main paper receiving table 1 is equipped with a paper discharge part 2 in two directions, which can realize paper discharge in two directions, greatly improving convenience and work efficiency;

[0032] like Figure 3 As shown, conveyor belts 4 are installed on both sides of each fence of the fence-type paper receiving platform 3, and the fence-type paper receiving platform 3 moves up and down between the conveyor belts.

[0033] The fence-type paper receiving platform 3 is provided with four installation corners, each of which is fixed to the main paper receiving platform plate 1 by screws.

[0034] like Figure 4 As shown, the barrier-type paper receiving platform 3 of the present invention is lowered to the bottom together with the main paper receiving platform 1, so that the paper pile 5 on the barrier-type paper receiving platform is placed on the conveyor belt 4, and the conveyor belt 4 is activated to convey the paper pile out of the machine.

[0035] like Figure 5 As shown, the paper receiving device also includes a retractable auxiliary paper receiving platform 6 for receiving cardboards sent from the previous process. The highest point of the fence-type paper receiving platform 3 is located at the bottom of the retractable auxiliary paper receiving platform 6. The auxiliary paper receiving platform receives the cardboards sent from the previous process until the fence-type paper receiving platform 3 rises to the bottom of the auxiliary paper receiving platform 6; the auxiliary paper receiving platform retracts, and the paper pile collected on the platform falls on the paper receiving fence of the fence-type paper receiving platform, and the fence paper receiving platform 3 continues to receive paper until a preset height or quantity; the fence-type paper receiving platform descends and passes through the conveyor belt, and the paper pile is placed on the conveyor belt during the descent, and the conveyor belt is activated to transport the paper pile out of the machine; at the same time, during the descent, when the top surface of the paper pile is lower than the extended height of the auxiliary paper receiving platform 6, the auxiliary paper receiving platform 6 extends to receive the paper.

The paper receiving device further includes an operation screen, which is used to input the number or height of the paper pile, and matches the height or number that the auxiliary paper receiving station can receive. In the high-pile paper receiving mode, when the paper receiving reaches the set height or number, the controller notifies the operator to move the machine out of the machine.

[0037] When selecting the cardboard quantity setting, because different cardboards may have different heights at the same quantity, in order to prevent the paper collection height from exceeding the maximum height allowed by the paper collection platform, a photoelectric detector for judging the maximum height of the paper collection pile is installed on the paper collection platform. When the photoelectric detector detects that the height of the paper collection pile reaches the maximum height, regardless of whether the set count value is reached, the paper pile will be automatically sent out or removed as a stack. If it is not sent out or removed in time, the controller will send a signal to make the machine take protective shutdown measures.
