Description

Technical Field

[0001] The utility model relates to a semi-finished product stacking and transferring system of an array type cup stacking machine. Background Art

[0002] At present, there are two types of plastic container cup making machines: one is a flip molded cup machine. After the air pressure thermoforming cup making machine automatically and quickly completes the shaping and punching, the lower mold body flips 90 degrees, and the cup bottom rod pushes the cup in the mold cavity out of the mold cavity to automatically stack and count the cups; however, the price of this equipment is particularly expensive, and due to the influence of the specifications and cavity number distance of the lateral mold cavity, the dense stacked cups, and the influence of the stacked cup guide frame, it is impossible to spot check the product quality in time. The other is a thermoforming cup making machine whose lower mold body cannot be flipped. Its upper mold body is fixed, and the lower mold body is raised and lowered. When it is lowered into place, the mold is closed, the shaping and punching are completed, and the mold is opened. When the lower mold body is in place, the cup bottom rod pushes the cup out of the mold cavity, and the high-pressure gas blows the cup out of the mold body. This air pressure thermoforming cup making machine that cannot flip the mold has similar production efficiency and cup making quality as the flip molded cup machine, but the price is one twentieth of the flip molded cup machine. Its disadvantage is that it cannot complete automatic counting and automatic cup stacking. At the same time, this cup making machine opens the mold after forming, punching and shearing, the mold bottom pushes the container out of the mold cavity, and the air pressure blows the cup out of the mold body and scatters it to the cup inspection position, and then the cup is inspected manually.

[0003] In order to solve the above problems, the commonly used cup stacking machine for plastic containers usually uses a robot to take out all the plastic containers in the mold of the molding machine at the same time, and then stack them into a long plastic container pile, and then send them out for packaging, so as to obtain the plastic container packaging we often see on the market. However, the disadvantage of this cup stacking method is that the mold of the molding machine usually has a large number of plastic containers, which are arranged in an array (such as 5 rows and 6 columns, 8 rows and 9 columns, etc.), and the action end of the robot is usually set on one side of the frame. The cup holder needs to be connected to the action end of the robot through a long arm. Therefore, the cup holder is prone to shaking during operation, which affects the accuracy of the cup taking action and easily causes the plastic container to be skewed, fall off, or unable to be taken out.

[0004] For example, a counting and stacking machine disclosed in a Chinese patent document with publication number CN103086160A and name “Automatic High-speed Cup Picking Counting and Stacking Machine” has a cup picking rack connected to the action end of the manipulator through a long arm. Therefore, the cup picking rack is prone to shaking during operation, affecting the accuracy of the cup picking action, and easily causing the plastic containers to be skewed, dropped, or unable to be taken out. Moreover, the plastic containers are prone to misalignment during the stacking operation, so that the stacking fails completely, the plastic container is stuck on the cup mouth of the next plastic container, and the plastic container stack overturns. Moreover, the number and height of the plastic containers in the plastic container stack are greatly limited (i.e., the semi-finished plastic container stack). After being transferred to the packaging station, they need to be manually stacked and counted again to obtain a finished plastic container stack with a sufficient number of plastic containers before packaging. The work efficiency is low, so this technology cannot meet the needs of large-scale industrial production.

[0005] In order to solve the above technical problems, the applicant has improved the cup picking and placing mechanism and the stacking mechanism of the cup stacking machine, so that the cup picking and placing mechanism can pick up and place cups smoothly, quickly and accurately, and the stacking mechanism can cooperate with the cup picking and placing mechanism to obtain finished plastic container stacks (because when packaging, usually 20 to 30 or even more finished plastic container stacks are stacked together for packaging). However, the applicant found that if the improved stacking mechanism completes the stacking of a large number of plastic containers at one time, the work efficiency cannot be further improved. In order to further improve the work efficiency, the applicant designed a plurality of stacking mechanisms to cooperate with the cup picking and placing mechanism in turn for stacking, and the stacking mechanism only stacks a small number of semi-finished plastic container stacks (the number of plastic containers is usually a fraction of the finished plastic container stacks). The applicant has improved the transfer mechanism so that the transfer mechanism can cooperate with the stacking mechanism to stack a plurality of semi-finished plastic container stacks to obtain finished plastic container stacks and send them out for packaging.
