[0026] The core of the present invention is to provide a product tray unloading and stacking system, which can transfer the entire tray of products to the flip tray at the same time through the mutual cooperation and flipping of the flip tray and the sterilization tray, so as to complete the transfer operation quickly and efficiently.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the product unloading and stacking system of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The present invention provides a product unloading and unstacking system, comprising an unstacking and transferring device 1, a turnover conveying device 2, a controller, etc. Figure 1 It is a top view schematic diagram of a specific embodiment of the product tray unloading and stacking system of the present invention, in which A represents the sterilization tray and the controller is not marked in the figure.

[0029] A chuck device is installed on the unpacking and transferring device 1, and the chuck device can clamp the sterilization tray and release the sterilization tray. When the chuck device clamps the sterilization tray, the two are fixed as one, and the sterilization tray is synchronously driven by the chuck device. When releasing, the sterilization tray is separated from the chuck device.

[0030] When the chuck device clamps the sterilization tray, the unpacking and transferring device 1 drives the chuck device and the sterilization tray to move synchronously; the chuck device and the unpacking and transferring device 1 are connected by a laterally extending rotating shaft, the chuck device can be flipped relative to the unpacking and transferring device 1, and the chuck device can be rotated at least 180 degrees relative to the unpacking and transferring device 1, and the lower surface of the chuck device faces upward after flipping.

[0031] The flip conveying device 2 includes a fixed base 21 and a flip bracket 22. The fixed base 21 is fixed on a supporting structure such as the ground. The flip bracket 22 is rotatably connected to the fixed base 21 via a transversely extending flip shaft 23. The flip bracket 22 can rotate relative to the fixed base 21 and can rotate at least 180 degrees.

[0032] The controller controls the unpacking and transferring device 1, which drives the sterilization tray to move to the bottom of the flip bracket 22, at which time the product is on the sterilization tray; the flip bracket 22 flips synchronously with the sterilization tray when it is in contact with the sterilization tray, and the flip bracket 22 flips to the bottom of the sterilization tray, and the sterilization tray flips to the top of the flip bracket 22, and the product automatically falls onto the flip bracket 22 due to gravity, and at this time the product is received by the flip bracket 22; the flip bracket 22 transfers the product placed thereon to the conveying device 3, so that the product is removed from the sterilization tray.

[0033] Combination Figure 2A and Figure 2B The figures are schematic diagrams of the flip bracket 22 and the sterilization tray before and after the flipping, respectively; the sterilization tray is first moved to the bottom of the flip bracket 22, and the product placed on the sterilization tray contacts the bottom surface of the flip bracket 22. At this time, the rotating axis of the flip bracket 22 is in line with the rotating axis of the chuck device; the flip bracket 22 and the chuck device are rotated synchronously, and the rotation angle is 180 degrees to reach Figure 2B In the state shown, the sterilization tray is located at the top and the products fall onto the turning bracket 22 due to gravity.

[0034] The present invention enables the product to complete the unloading process by cooperating between the unloading and transferring device 1 and the flip bracket 22; the unloading and transferring device 1 is used to grab and transfer the sterilization tray to complete the unloading and stacking processes. The unloading and transferring device 1 is used to simultaneously operate the unloading, stacking, and product transfer processes, thereby reducing the use of special machinery, achieving the effect of simplifying the structure, and reducing maintenance costs.

[0035] Specifically, the flip bracket 22 used in the present invention is a flip conveyor belt, which is connected to the conveying device 3. The flip conveyor belt can drive the products placed thereon to move toward the conveying device 3. The flip conveyor belt is driven by a motor to circulate the belt to realize the transportation and transfer of the products. The conveying device 3 can also adopt the structure of a conveyor belt. The two conveyor belts are connected to each other to complete the handover of the products. After the products on the flip bracket 22 are moved out, new products can be received again.

[0036] In addition to using a belt, the flip bracket 22 can also be set as a vibration plate. After receiving the product, the vibration plate is slightly tilted, and then the product on it is gradually slid onto the conveying device 3 through vibration. These specific embodiments should all be included in the protection scope of the present invention.

[0037] As for the structure of the belt, the present invention further arranges the driving motor of the flip conveyor belt on the side, and both the front and back sides of the flip conveyor belt can drive the product to move. When the flip bracket 22 flips 180 degrees to receive the product, it can receive the next batch of products without turning back. After rotating 360 degrees, the transfer process of two batches of products can be completed.

[0038] The product unloading and stacking system of the present invention further comprises a telescopic support device, the main structure of which is fixed on a support structure such as the ground, and the telescopic support device is not shown in the figure; the telescopic support device is located at the cantilever end of the flip bracket 22, Figure 2A and Figure 2B The left end is the supporting end, and the right end is the cantilever end. The telescopic pin arranged on the telescopic supporting device can be inserted into the flip bracket 22 to provide support for the cantilever end.

[0039] When the flip bracket 22 flips over to receive the product, in order to maintain a horizontal state and avoid accidental rotation, the telescopic pin provided on the telescopic support device extends outward and is inserted into one end of the cantilever of the flip bracket 22 to avoid rotation.

[0040] like Figure 3 The figure is a schematic diagram of the structure of the chuck device, which is a "U"-shaped three-sided frame structure, which is in contact with the three sides of the sterilization tray respectively; a positioning pin is telescopically arranged on the chuck device, and the positioning pin can be inserted into the positioning hole on the side of the sterilization tray to contact and clamp the sterilization tray.

[0041] The product unloading and unstacking system of the present invention also includes a full tray sterilization cart 4 and an empty tray sterilization cart 5. The full tray sterilization cart 4 and the empty tray sterilization cart 5 are located on one side of the unstacking and transferring device 1, and the flip conveying device 2 is located on the other side of the unstacking and transferring device 1. The unstacking and transferring device 1 continuously drives the sterilization tray to circulate among the full tray sterilization cart 4, the flip conveying device 2, and the empty tray sterilization cart 5.

[0042] Specifically, the unpacking and transferring device 1 in the present invention is a six-axis robot; a detector for detecting the presence of a sterilization tray is installed on the chuck device, and when the detector detects that the sterilization tray is not grasped, it needs to be grasped again.

[0043] On the basis of any of the above technical solutions, the present invention provides a specific setting structure, wherein two unpacking and transferring devices 1 are matched with a corresponding flip conveying device 2, and the two unpacking and transferring devices 1 transfer products to the flip conveying device 2 alternately.

[0044] Figure 1 A turnover conveying device 2 and a stacking and transferring device 1 are provided in the invention, and the stacking, flipping and stacking of the trays are completed by the stacking and transferring device 1. In order to improve the efficiency of the transfer, Figure 4 As shown, it is a structural diagram of the second embodiment of the product unloading and destacking system of the present invention, in which two destacking transfer devices 1 are provided, and the two destacking transfer devices 1 work alternately to match with the flip conveying device 2. In the figure, the destacking transfer device 1 at the lower position is cooperating with the flip conveying device 2, and the destacking transfer device 1 at the upper position is placing an empty tray. This arrangement improves the efficiency of product transfer.

[0045] like Figure 5 As shown, it is a structural diagram of the third embodiment of the product unloading and stacking system of the present invention; two unloading and transferring devices 1 are matched with two corresponding flip conveying devices 2, each unloading and transferring device 1 is matched with one flip conveying device 2, and the two flip conveying devices 2 are matched with two branches of the corresponding conveying device 3.
