Description

Technical Field

[0001] The present invention relates to the technical field of product production transfer, and further to a product palletizing and unpalletizing system. Background Art

[0002] Medical infusion soft bags or blood bags need to be transferred and transported during the production process. The soft bags are loaded onto sterilization trays. Multiple sterilization bags can be placed in each sterilization tray in a horizontal and vertical arrangement. The soft bags on the entire sterilization tray are transported as a whole for subsequent sterilization and other operations.

[0003] Sterilization trays are stacked and placed in the sterilization cart, which transfers the sterilization trays in batches. Empty sterilization trays are removed from the sterilization cart for loading, and sterilization trays filled with soft bags are stacked layer by layer and placed in the sterilization cart. The unpacking and stacking of sterilization trays are completed by two sterilization tray unpacking and stacking machines or two industrial robots.

[0004] At present, large-volume infusion automatic logistics systems usually use telescopic bagging machines or spider-arm robots to grab soft bags one by one, and cooperate with sterilization tray transfer and stepping mechanisms to transfer the soft bags one by one to the sterilization tray after the tray is removed. After filling, the soft bags are placed on another sterilization cart to complete the stacking.

[0005] Currently, this soft bag packaging method occupies a large area and requires the use of multiple dedicated machines. It is a dedicated equipment with high maintenance requirements and poor versatility.

[0006] For those skilled in the art, how to reduce the complexity of the special machines required for soft bag palletizing and improve turnover efficiency is a technical problem that needs to be solved at present. Summary of the Invention

[0028] The core of the present invention is to provide a product tray loading and unloading system, in which the unloading tray and the product are placed through a unloading and transferring device, which reduces the complexity of the overall structure, improves turnover efficiency, and is easier to maintain.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the product loading and unloading system of the present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figure 1The figure shows a top view of a specific embodiment of the product tray loading and unloading system provided by the present invention, in which A represents a sterilization tray. The system includes a product conveying device 1, an unloading and transferring device 2, a controller, etc. (the controller is not shown in the figure). The product conveying device 1 is used to convey products, and the products are driven by the product conveying device 1 and arranged and moved on the product conveying device 1. The end of the product conveying device 1 is not blocked, so the products can move out of the end of the product conveying device 1 and fall. The products have inertia during movement, and when they move to the end position of the product conveying device 1, they are unobstructed and continue to move forward, and can fall from the product conveying device 1. As the product conveying device 1 continuously conveys products, the products continuously fall from the end.

[0031] A chuck device 3 is provided on the unstacking and transferring device 2. The chuck device 3 is driven by the unstacking and transferring device 2. The chuck device 3 can be moved to different positions to perform different operations. The chuck device 3 can clamp the sterilization tray. When the chuck device 3 clamps the sterilization tray, the two are fixed as one, and the sterilization tray and the chuck device 3 keep moving synchronously. After the chuck device 3 is relaxed at the designated position, the sterilization tray is put down, and the sterilization tray and the chuck device 3 are separated from each other.

[0032] During use, the unpacking and transferring device 2 drives the clamping device 3 to move between the product conveying device 1 and the sterilization tray placement position.

[0033] The movement between the various devices is controlled by a controller. The unpacking and transfer device 2 drives the chuck device 3 to the sterilization tray placement position, picks up an empty tray, and then the controller controls the unpacking and transfer device 2 to drive the chuck device 3 to the end of the product conveying device 1, where the sterilization tray receives the dropped product. The products are placed in only one layer on the sterilization tray, without overlapping each other. Therefore, the unpacking and transfer device 2 drives the sterilization tray along a preset path, arranging the dropped soft bags in an array on the sterilization tray until the sterilization tray is completely filled with products. The full sterilization tray is then returned to the sterilization tray placement position, completing the sterilization tray placement process. A new empty tray is then taken and the product placement process is repeated.

[0034] The end of the product conveyor 1 continuously drops products at intervals. During this process, the sterilization tray below, after receiving a dropped product, moves horizontally a distance to continue receiving a new dropped product. The intermittent delivery of the product conveyor 1 and the step-by-step movement of the sterilization tray work together until the product is full. The unpacking and stacking device 2 not only completes the process of loading the product onto the tray, but also is used to remove and stack the sterilization tray from its position. A single structure completes the three steps of unpacking, receiving products, and stacking, reducing the structure required for the entire system.

[0035] The product loading and unloading system of the present invention utilizes the mutual cooperation between the product conveying device 1 and the unloading and transferring device 2 so that the products are automatically arranged and distributed after being dropped. There is no need to set up a separate clamping mechanism. The placement of the unloading tray and the products is completed by the unloading and transferring device 2 in one structure, which reduces the complexity of the overall structure, improves turnover efficiency, and is more convenient for maintenance.

[0036] Based on the above solution, the present invention provides an empty tray sterilization cart 4 and a full tray sterilization cart 5 for placing sterilization trays. The empty tray sterilization cart 4 is used to place empty sterilization trays, while the full tray sterilization cart 5 is used to place full sterilization trays. The unstacking and transferring device 2 unstacking and grabbing empty trays from the empty tray sterilization cart 4, and after the sterilization trays are filled with products, stacking and placing the sterilization trays on the full tray sterilization cart 5. In other words, the empty tray sterilization cart 4 and the full tray sterilization cart 5 are both located on a moving path accessible by the unstacking and transferring device 2. The empty tray sterilization cart 4 and the full tray sterilization cart 5 can drive the sterilization trays placed thereon to be transferred as a whole.

[0037] The unpacking and transferring device 2 in the present invention is two independently working industrial robots, which load the trays alternately. Figure 1 As shown, two industrial robots are arranged side by side, the product conveying device 1 is located on the left side of the two industrial robots, and the empty tray sterilization cart 4 and the full tray sterilization cart 5 are located on the right side of the two industrial robots; the two industrial robots respectively drive the sterilization trays to move along the circle shown by the dotted line. Figure 1 The industrial robot in the upper middle grabs the empty sterilization tray and moves it to the end of the product conveying device 1 to catch the fallen products; the industrial robot below grabs the tray in the stacking position and places the sterilization tray filled with products on the full tray sterilization cart 5.

[0038] The controller drives the unpacking and transferring device 2 to make the chucking device 3 move back and forth horizontally along an "S"-shaped path or a spiral path to receive the products. Figure 2A This is a schematic diagram of the sterilization tray moving along an "S"-shaped path. Figure 2B Schematic diagram of the sterilization tray moving along a spiral path; the dotted arrows in the figure indicate the path along which the products are placed, and the sterilization tray is divided into several rows horizontally in the figure.

[0039] Figure 2A During the movement of the "S"-shaped path shown, the edge row of the sterilization tray is first placed directly opposite the end of the product conveying device 1. After the product fills one row of the sterilization tray, the next adjacent row is placed directly opposite the end of the product conveying device 1. Figure 2A The odd-numbered rows receive products from the right, and the even-numbered rows receive products from the left.

[0040] Figure 2B During the spiral path movement, the sterilization tray will first be filled with products on the outer side, and then the sterilization tray will move along the spiral path, gradually placing products inward until the sterilization tray is completely filled with products.

[0041] Specifically, during the operation, the controller controls an industrial robot to complete the loading of the first sterilization tray, and then another industrial robot places the second sterilization tray under the first sterilization tray to wait for loading; Figure 3A and Figure 3B As shown in the figure, there are a front view and a top view of the alternating states of two sterilization trays, wherein the upper sterilization tray is the sterilization tray filled with products, and the lower sterilization tray is an empty sterilization tray. Before the full tray above is moved out, the empty tray below can already hold products; when the full tray above is completely moved out, the empty tray below moves upward close to the product conveying device 1, replacing the original full tray position; thereafter, the empty tray moves horizontally along the preset path until the sterilization tray is completely filled with products; and this cycle repeats.

[0042] Combine Figure 4 The figure shows a schematic diagram of the structure of the chuck device 3; the chuck device 3 is a "U"-shaped frame structure, which can contact the three sides of the sterilization tray; a telescopic positioning pin is provided on the chuck device 3, and the telescopic positioning pin is located on the inner side, close to the sterilization tray. The telescopic positioning pin can be retracted or extended. When it is extended, the telescopic positioning pin can be stuck in the positioning hole on the side of the sterilization tray to fix the sterilization tray and play a supporting role.

[0043] Specifically, the product conveying device 1 in the present invention is a belt conveyor, and a conveyor roller can also be used. These specific configurations should all be included in the protection scope of the present invention.

[0044] The chuck device 3 is provided with a detection device for monitoring whether there is a sterilization tray. If the sterilization tray is not detected, an error is reported and the chuck device 3 is re-grasped until the sterilization tray is detected, thereby preventing the sterilization tray from being mis-grasped.

[0045] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
