[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] The following Figures 1 to 4 , describes the embodiments of the present invention.

[0031] According to an embodiment of the present invention, there is provided a paper tray separation device, including: a body 1, a tray separation mechanism 5, a lifting mechanism 7, an auxiliary mechanism 8 and a detection mechanism.

[0032] Specifically, the body 1 is provided with a paper tray bin 2, and there are multiple paper trays in the paper tray bin 2. The adjacent paper trays are stacked on top of each other. The multiple paper trays include the lowermost first paper tray 3 and the second paper tray 4 adjacent to the first paper tray 3. The paper tray separating mechanisms 5 are arranged on two opposite sides of the paper tray bin 2. The paper tray separating mechanisms 5 include multiple separating pieces 6. When the separating pieces 6 are in the first position, the separating pieces 6 extend into the gap between the first paper tray 3 and the second paper tray 4 and lap with the bottom edge of the second paper tray 4. When the separating pieces 6 are in the second position, the separating pieces 6 are away from the gap. The lifting mechanism 7 is connected to the paper tray separating mechanisms 5. When the separating pieces 6 are in the first position, the lifting mechanism 7 drives the separating pieces 6 to move along the direction of gravity. The auxiliary mechanism 8 is arranged on the body 1. The auxiliary mechanism 8 is located below the paper tray separating mechanisms 5. The auxiliary mechanism 8 includes a rotatable knocking piece 801. The knocking piece 801 has a first movement of rotating towards the direction close to the first paper tray 3 and knocking the first paper tray 3, and a second movement of rotating away from the first paper tray 3. The detection mechanism is arranged on the body 1. The detection mechanism is signal-connected to the control system, and the control system is signal-connected to the auxiliary mechanism 8 to control the auxiliary mechanism 8 to perform the first movement or the second movement.

[0033] In this embodiment, multiple stacked paper trays can be placed in the paper tray bin 2 of the machine body 1. The paper tray separating mechanism 5 can separate the stacked paper trays one by one and convey them to the packaging process through the conveying device at the bottom of the paper tray bin 2. The lowermost paper tray among the multiple paper trays is the first paper tray 3, and the second paper tray 4 is adjacent to the first paper tray 3. The paper tray separating mechanism 5 can separate the first paper tray 3 from the second paper tray 4. The separated first paper tray 3 will fall onto the conveying device (not shown), and the separated second paper tray 4 will become the new first paper tray 3, and the paper tray adjacent to the second paper tray 4 will become the new second paper tray 4. The paper tray separating mechanism 5 includes multiple separating pieces 6. The separating pieces 6 can be driven into the gap between the first paper tray 3 and the second paper tray 4. The separating pieces 6 are lapped with the bottom edge of the second paper tray 4. At this time, the separating pieces 6 are in the first position. The lifting mechanism 7 drives the paper tray separating mechanism 5 to rise along the direction of gravity. The paper tray separating mechanism 5 drives the separating pieces 6 to rise. The separating pieces 6 will lift the second paper tray 4 and the other paper trays above the second paper tray 4, causing the second paper tray 4 and the other paper trays above the second paper tray 4 to rise. The first paper tray 3 is separated from the second paper tray 4 under the action of gravity. The detection mechanism can detect the position information of the first paper tray 3. If the first paper tray 3 and the second paper tray 4 rise simultaneously, the detection mechanism determines that the first paper tray 3 and the second paper tray 4 are not separated. Subsequently, this information can be transmitted to the control system (not shown), and the control system controls the auxiliary mechanism 8 to act. The knocking piece 801 rotates towards the direction close to the first paper tray 3 and knocks on the side of the first paper tray 3 to separate the first paper tray 3 from the second paper tray 4. After the detection mechanism detects that the first paper tray 3 and the second paper tray 4 are separated, it transmits a signal to the control system, and the control system controls the knocking piece 801 to rotate away from the first paper tray 3 and reset. After the first paper tray 3 and the second paper tray 4 are separated, the lifting mechanism 7 drives the paper tray separating mechanism 5 to descend along the direction of gravity. The separating pieces 6 drive the second paper tray 4 and the other paper trays above the second paper tray 4 to descend. After the separating pieces 6 descend to the first position, the control system drives the separating pieces 6 to move to the second position, that is, away from the second paper tray 4. The multiple paper trays will move downward under the action of gravity after lacking the support of the separating pieces 6. At this time, the control system drives the separating pieces 6 to move to the first position. After the separating pieces 6 move to the first position, they will be exactly between the new first paper tray 3 and the new second paper tray 4, and the separating pieces 6 will be lapped with the bottom edge of the new second paper tray 4.

[0034] Preferably, the control system is a PLC controller, and the PLC controller can be signal-connected to the lifting mechanism 7, the detection mechanism, the auxiliary mechanism 8, and the paper tray separating mechanism 5 respectively.

[0035] By providing the auxiliary mechanism 8, when the first paper tray 3 and the second paper tray 4 cannot be separated, the striking piece 801 can rotate towards the first paper tray 3 and strike the first paper tray 3. After being struck, the first paper tray 3 will separate from the second paper tray 4. The paper tray separating device disclosed in this application helps to reduce the time for dealing with paper trays that do not automatically separate, improves production efficiency. At the same time, it can also avoid manual handling of paper trays that do not automatically separate, reducing labor consumption.

The rotation of the gear 8031 drives the rotating shaft 8032 to rotate. The rotating shaft 8032 drives the striking piece 801 to complete the first action or the second action. A plurality of striking pieces 801 are arranged at intervals on the rotating shaft 8032. The number of the striking pieces 801 and the interval between adjacent striking pieces 801 can be determined according to the length of the rotating shaft 8032 and other processes, and are not limited herein.
