Description

Technical Field

[0001] The utility model relates to a clamping cup taking and placing mechanism of an array 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 made multiple improvements to the cup picking and placing mechanism and the stacking mechanism of the above 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 plastic container stack products (because when packaging, plastic container stack products with a number of twenty to thirty or even more stacked together are usually packaged).

[0006] However, the applicant found that the improved cup-taking mechanism still uses the method of inserting the vacuum suction cup into the plastic container to suck the bottom surface of the plastic container to complete the cup-taking work. This means that once the mold of the molding machine is replaced and the depth of the plastic container is changed, the stroke of the vacuum suction cup needs to be adjusted, which is very troublesome to operate. In addition, since the vacuum suction cup needs to descend to suck the plastic container and then rise to leave the mold, the cup-taking step has too many actions and takes a long time, but the number of actions cannot be reduced, so the manufacturer cannot further improve the work efficiency. In addition, because the market changes too quickly, the size of the plastic container to be processed often changes greatly, and not only the depth changes, but also the cup mouth size changes, which requires the cup-taking mechanism to be able to cope with the changes in the depth size and / or cup mouth size. Utility Model Content

[0007] The purpose of the utility model is to provide a clamping cup picking and placing mechanism for an array cup stacking machine, which can quickly complete the cup picking work on the surface of the mold and is suitable for all plastic containers with a diameter smaller than the cup hole. The technical solution adopted is as follows:

[0008] A clamping cup picking and placing mechanism for an array cup stacking machine is characterized in that it includes a mounting frame, a clamping frame and a telescopic member of the clamping frame, wherein the clamping frame is slidably arranged on the top surface of the mounting frame, the telescopic member of the clamping frame is installed on the top surface of the mounting frame, the telescopic member of the clamping frame has a telescopic end, the telescopic end is connected to the clamping frame and moves the clamping frame on the top surface of the mounting frame; the mounting frame is provided with at least one cup hole, the clamping frame includes a positioning frame and at least one clamping unit, the number of the clamping units and the cup holes are the same and correspond one to one, and when the clamping frame moves, each clamping unit cooperates with the corresponding cup hole to clamp the cup mouth of a plastic container passing through the cup hole from bottom to top.

[0009] In a more preferred solution, the clamping unit includes a vertical clamping edge, a horizontal clamping edge, and a clamping bevel edge, and the two ends of the horizontal clamping edge are respectively connected to the bottom end of the vertical clamping edge and the right end of the horizontal clamping edge.

[0010] A more optimal solution is that the clamping unit also includes a reinforcing beveled edge and a horizontal connecting edge, the left end of the horizontal connecting edge is connected to the right end of the horizontal clamping edge, the right end of the horizontal connecting edge is connected to the left end of the horizontal connecting edge or the positioning frame of the clamping unit located on the right side of the clamping unit, and the two ends of the reinforcing beveled edge are respectively connected to the vertical clamping edge and the horizontal connecting edge.

[0011] In a more preferred solution, at least one swing amplitude limiting member is installed on the top surface of the mounting frame, and two ends of the swing amplitude limiting member are respectively hinged to the mounting frame and the clamping frame.

[0012] A more optimal solution is that there are multiple swing amplitude limiting members, and the vertical clamping side end, horizontal clamping side end, and horizontal connecting side end of any clamping unit are respectively connected to different swing amplitude limiting members.

This structural design can most effectively utilize the space of the mounting frame.

[0014] Compared with the prior art, the beneficial effect of the utility model is that, since the telescopic part of the clamping frame is used to drive the clamping frame to slide on the top surface of the mounting frame, the clamping unit is used to cooperate with the corresponding cup hole to clamp the cup mouth of the plastic container passing through the cup hole from bottom to top, during the process of taking and placing the cup, the clamping cup taking and placing mechanism does not need to extend into the plastic container to complete the cup taking work, thus saving this section of the descending process and the subsequent ascending process, thereby being able to further improve work efficiency, and the applicable plastic container cup mouth size range is very large, and the depth of the plastic container is not limited.

The mounting frame 1 has at least one cup hole 101. The clamping frame 2 includes a positioning frame 201 and at least one clamping unit 202. The number of the clamping units 202 and the cup holes 101 is the same and corresponds one to one. When the clamping frame 2 moves, each clamping unit 202 cooperates with the corresponding cup hole 101 to clamp the cup mouth of the plastic container passing through the cup hole 101 from bottom to top. In this embodiment, the number of cup holes 101 is multiple, and the number of clamping units 202 is multiple.

[0022] like Figure 4 , 5 As shown, an optional embodiment of the present application, the clamping unit 202 includes a vertical clamping edge 2021, a horizontal clamping edge 2022, and a clamping bevel 2023, and the two ends of the horizontal clamping edge 2022 are respectively connected to the bottom end of the vertical clamping edge 2021 and the right end of the horizontal clamping edge 2022.

[0023] like Figure 4 , 5As shown, an optional embodiment of the present application, the clamping unit 202 also includes a reinforcing bevel 2024 and a horizontal connecting edge 2025, the left end of the horizontal connecting edge 2025 is connected to the right end of the horizontal clamping edge 2022, the right end of the horizontal connecting edge 2025 is connected to the left end of the horizontal connecting edge 2025 of the clamping unit 202 located on the right side of the clamping unit 202 or the positioning frame 201, and the two ends of the reinforcing bevel 2024 are respectively connected to the vertical clamping edge 2021 and the horizontal connecting edge 2025.

[0024] like Figure 1 , 2 As shown in Figures 4 and 5, an optional embodiment of the present application is that at least one swing amplitude limiting member 4 is installed on the top surface of the mounting frame 1, and the two ends of the swing amplitude limiting member 4 are hinged to the mounting frame 1 and the clamping frame 2 respectively.

[0025] like Figure 1 , 2 As shown in Figures 4 and 5, an optional embodiment of the present application is that the number of the swing amplitude limiting members 4 is multiple, and the end of the vertical clamping edge 2021, the end of the horizontal clamping edge 2022, and the end of the horizontal connecting edge 2025 of any clamping unit 202 are respectively connected to different swing amplitude limiting members 4.

[0026] like Figure 1 As shown, in an optional embodiment of the present application, the telescopic member 3 of the clamping frame is a cylinder, and the telescopic end 301 is the piston shaft of the cylinder.

[0027] like Figure 1 , 6 As shown, an optional embodiment of the present application, the number of the cup holes 101 is multiple, and all the cup holes 101 form at least two cup hole groups 102 parallel to each other, each cup hole group 102 includes multiple cup holes 101, and any two adjacent cup hole groups 102, the cup holes 101 of one cup hole group 102 are arranged in the gap between two adjacent cup holes 101 of another cup hole group 102.

In this embodiment, there are six cup hole groups 102, and each cup hole group 102 includes three cup holes 101.

[0028] Combine the following Figure 1-6 The working process of this embodiment is introduced:

[0029] When taking a cup, first, the mounting frame 1 moves to the top of the mold of the molding machine. Then, the mounting frame 1 descends until the mounting frame 1 is against the top of each mold hole of the mold, and the cup pushing component of the molding machine works, so that the plastic container in each mold hole rises, and the cup mouth of the plastic container extends from the cup hole 101 of the mounting frame 1 and reaches above the clamping frame 2. Next, the clamping frame telescopic member 3 works, and its telescopic end 301 extends, so that each clamping unit 202 cooperates with the corresponding cup hole 101 to clamp the plastic container in each cup hole 101. Finally, the mounting frame 1 rises, takes the plastic container out of the mold, and then moves to the cup stacking station of the cup stacking machine and puts down all the plastic containers.

[0030] Since the clamping cup-taking and cup-placing mechanism can complete the cup-taking work without inserting into the plastic container during the process of taking and placing the cup, compared with the traditional vacuum suction cup cup-taking method, this section of the descending process and the subsequent ascending process are saved, so the work efficiency can be further improved. Moreover, the clamping cup-taking and cup-placing mechanism of this embodiment can be applied to a wide range of plastic container cup opening sizes (all plastic containers with cup opening sizes smaller than the inner diameter of the cup hole 101 are applicable), and the depth of the plastic container is not limited.

[0031] In addition, it should be noted that the names of the various parts of the specific embodiments described in this specification may be different, and any equivalent or simple changes made based on the structure, features and principles described in the utility model patent concept are included in the protection scope of the utility model patent.
