[0037] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific implementation modes.

[0038] Embodiment 1

[0039] As Figures 1 - 9As shown in the figure, the present invention provides a tray continuous separation device, including a separation mechanism 1 and a control module. The separation mechanism 1 includes two separation rollers 11 rotatably mounted on a frame. The two separation rollers 11 are symmetrically arranged on both sides of the tray 100. A plurality of separation components 111 extending along the axial direction of the separation roller 11 are arranged on the outer periphery of the separation roller 11, and the plurality of separation components 111 are evenly distributed along the outer periphery of the separation roller 11. The control module can control the two separation rollers 11 to rotate synchronously and reversely around the axis. In this embodiment, five groups of separation components 111 are evenly distributed on the outer periphery of the separation roller 11. The control module controls the separation rollers 11 on both sides of the tray 100 to rotate synchronously (or only drives one side of the separation roller 11 to rotate, and the other side of the separation roller 11 follows). Among them, the separation roller 11 on the left side of the tray 100 rotates clockwise, and the separation roller 11 on the right side of the tray 100 rotates counterclockwise. The separation components 111 on the separation roller 11 are inserted into the gap between the bottommost tray 100 and the second bottommost tray 100, and the tray 100 at the bottommost layer is forcibly separated.

[0040] In this embodiment, the separation components 111 are divided into two structural types: single-arm type and double-arm type. Among them, the single-arm type separation component 111 is as Figure 2 shown. It includes a supporting arm 1111. One end of the supporting arm 1111 is fixedly connected to the separation roller 11, and the other end of the supporting arm 1111 extends radially along the separation roller 11. This type of separation component 111 has a simple structure and is suitable for the situation where the nesting between trays 100 is relatively loose. The supporting arm 1111 serves to both support and separate the trays 100. This type of separation component 111 mainly separates the bottom tray 100 by relying on the self-weight of the tray 100. The double-arm type separation component 111 is suitable for the situation where the nesting between trays 100 is relatively tight and cannot be separated by relying on the self-gravity of the tray 100.

[0041] Specifically, the double-arm type separation component 111 includes three types of structures. On the basis of including the supporting arm 1111, the double-arm type separation component 111 of the first type also includes a first separation arm 1112, as Figure 3 and Figure 4 shown. One end of the first separation arm 1112 is fixedly connected to the other end of the supporting arm 1111, and the other end of the first separation arm 1112 extends away from the separation roller 11. The included angle between the first separation arm 1112 and the supporting arm 1111 is preferably an obtuse angle. Among them, for the separation component 111 with the first separation arm 1112 and the supporting arm 1111 shown in Figure 3 the first separation arm 1112 not only serves to forcibly separate the trays 100. When the separation roller 11 drives the first separation arm 1112 to rotate, the first separation arms 1112 on both sides of the tray 100 slide down along the inclined side walls of the tray, and center-align the left and right sides of the tray 100, so that the tray 100 is always in the central position. Figure 4The shown separating component 111, due to the non - connection of the head and tail of the first separating arm 1112 and the supporting arm 1111 (in a fork - like structure), the lengths of the first separating arm 1112 and the supporting arm 1111 do not affect each other. The lengths of the first separating arm 1112 and the supporting arm 1111 can be customized according to the actual working conditions respectively. When the continuous separation of the tray 100 is affected by the longer first separating arm 1112 or supporting arm 1111, the first separating arm 1112 or the supporting arm 1111 can be cut and polished on - site to meet the requirements of transmission and separation.

[0042] As Figure 5 shown, one end of the second separating arm 1113 of the separating component 111 of the double - arm type II structure is fixedly connected to the other end of the supporting arm 1111, and the other end of the second separating arm 1113 extends along the circumferential direction of the separating roller 11. The second separating arm 1113 is a curved surface structure, which can not only forcibly separate the tray 100, but also facilitate transportation and handling. Its unique curved surface structure provides convenience for handling and stacking storage.

[0043] As Figure 6 shown, one end of the third separating arm 1114 of the separating component 111 of the double - arm type III structure is fixedly connected to the separating roller 11, and the other end of the third separating arm 1114 extends along the radial direction of the separating roller 11. The length of the third separating arm 1114 is greater than the length of the supporting arm 1111, so that the third separating arm 1114 can forcibly separate the tray 100. The lengths of the third separating arm 1114 and the supporting arm 1111 do not affect each other, and the lengths of the third separating arm 1114 and the supporting arm 1111 can be customized according to the actual working conditions respectively.

[0044] Preferably, when the supporting arm 1111 is in a horizontal position, the distance H1 between the other end of the first separating arm 1112 and the tray 100 is greater than or equal to the gap H2 between two adjacent trays 100. As Figure 7 shown, in this embodiment, taking the separating component 111 of the double - arm type I structure as an example, the distance H1 ≥ the distance H2, so that the first separating arm 1112 can forcibly separate the tray 100 and prevent the trays 100 from being nested too tightly to be automatically separated by gravity.

[0045] Preferably, the distance H3 between the other end of the first separating arm 1112 and the side wall 110 of the tray is ≥ 0mm, preferably H3 > 0mm, which can effectively prevent the separating rollers 11 on the left and right sides of the tray 100 from squeezing the side wall of the tray 100 and causing mutual damage.

[0046] Preferably, the control module in this embodiment includes a driver and a PLC controller. The driver drives the two separating rollers 11 to rotate synchronously and reversely, and the PLC controller controls the start and stop of the driver. Among them, the driver uses a dual encoder and a detector to achieve precise control of the separating roller 11. The driver and the PLC controller are common control devices in the art, and their specific structures and principles will not be elaborated in this embodiment.

[0047] This embodiment also discloses a tray continuous separation device, including a propulsion device and the above-mentioned tray continuous separation device. The propulsion device is a common device in the art and can push the stack of trays onto the two separating rollers 11, so that the bottom tray 100 leans against the separating components 111 on both sides. The control module can control the start and stop of the propulsion device and the rotation speed of the separating rollers 11 on both sides of the tray 100.

[0048] Embodiment Two

[0049] This embodiment discloses a tray continuous separation method, as Figure 8 and Figure 9 shown, using the above-mentioned tray continuous separation device, including the following steps:

[0050] S1: The propulsion device starts and pushes the stack of trays onto the separating components 111 of the two separating rollers 11;

[0051] In this step, the control module controls the propulsion device to push the stacked trays onto the two separating rollers 11, so that the bottom tray 100 leans against the separating components 111 on both sides.

[0052] S2: The tray continuous separation device starts, and the two separating rollers 11 rotate synchronously and reversely, and the separating component 111 separates the bottom tray 100;

[0053] In this step, when the stack of trays in S1 is placed, the control module controls the separating rollers 11 (or one separating roller 11) on both sides of the tray 100 to rotate. The separating roller 11 on the left side of the tray 100 rotates clockwise, and the separating roller 11 on the right side of the tray 100 rotates counterclockwise. The separating component 111 on the separating roller 11 extends into the gap between the bottom layer and the second bottom layer tray (100) to separate the bottom tray 100.

[0054] S3: The separation of the bottom tray 100 is completed and it falls onto the conveyor belt and is conveyed out along with the conveyor belt;

[0055] In this step, the separation of the bottom tray 100 is completed. The tray 100 falls under the action of gravity and falls onto the lower conveyor belt or other conveying devices, and the tray 100 is conveyed out along with the conveyor belt or the conveying device.

[0056] S4: Repeat steps S2 - S3 until all the trays 100 on the stack of trays are separated.

[0057] In this step, after all the trays 100 on the separating roller 11 are separated, the control module controls the separating roller 11 to stop rotating, starts the pushing device, pushes a new stack of trays onto the two separating rollers 11, and repeats the separation operation.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
