Description

Technical Field

[0001] This utility model belongs to the field of food packaging production lines and relates to a spider-hand loading mechanism. Background Technology

[0002] In food packaging production lines, the gripping and handling of bagged products like Want Want Little Buns is a crucial step. However, existing suction cup gripping devices have the following problems when handling such products:

[0003] The surface of the packaging bag is uneven, and the packaging material and the shape of the product inside result in a lack of a flat suction surface. Traditional suction cup gripping devices mainly rely on the suction cup to adhere tightly to the surface of the object to create negative pressure for gripping. This uneven surface makes it difficult for the suction cup to make full contact with the product, making it difficult to create effective negative pressure, resulting in a weak grip or even failure to grip.

[0004] Meanwhile, Want Want Little Buns are fragile products. If the existing suction cup gripping device has insufficient suction force during operation, the product may fall and break due to shaking. If the suction force is too large, the product may be damaged due to excessive impact when it is put down.

[0005] In addition, modern food packaging production lines typically have high transmission speeds, and existing suction cup gripping devices cannot keep up with the rapid pace of the production line, often resulting in problems such as untimely gripping and inaccurate positioning, which seriously affects production efficiency.

[0006] Therefore, it is necessary to improve existing technologies to overcome their shortcomings. Utility Model Content

[0007] The purpose of this invention is to provide a spider-hand loading mechanism that can adapt to the high-speed transmission requirements of the production line and solve at least one problem in the background art.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] A spider-hand loading mechanism is installed on a packaging production line, including a fixed frame and a spider-hand robot installed on the fixed frame. The spider-hand robot is provided with a carrier plate, and the carrier plate is provided with at least one set of material gripping components.

[0010] The material gripping assembly includes a vertical cylinder, and a lifting plate is fixedly installed on the piston end of the vertical cylinder. Several vacuum suction cups with corrugated pipe structures are arranged around the lower part of the lifting plate.

[0011] Below the lifting plate is an adjustable-height pressure plate. The lower end of the pressure plate is higher than the lower end of the vacuum suction cup, forming a height difference, which is used to limit the distance the vacuum suction cup presses down after contacting the material.

[0012] As a further improvement of one embodiment of the present invention, the carrier plate is provided with two sets of independent material gripping components, each set of material gripping components being controlled by an independent air path.

[0013] As a further improvement of one embodiment of the present invention, the compression stroke of the vacuum suction cup is greater than the height difference between the pressure plate and the lower end face of the vacuum suction cup.

[0014] As a further improvement of one embodiment of the present invention, the carrier plate is provided with a first adjustment groove, the vertical cylinder is disposed below the carrier plate, and the bolt passes through the first adjustment groove to lock the vertical cylinder on the carrier plate.

[0015] As a further improvement of one embodiment of the present invention, the pressure plate is provided with a plurality of screws, the lifting plate is provided with through holes for the screws to be inserted, and the screws are positioned on the lifting plate by nuts.

[0016] As a further improvement of one embodiment of the present invention, the lifting plate is provided with a suction cup hole for inserting a vacuum suction cup, a second adjustment groove is provided around the suction cup hole, a mounting plate is provided on the vacuum suction cup, and bolts pass through the second adjustment groove and are locked on the mounting plate.

[0017] As a further improvement of one embodiment of the present invention, the number of the second adjustment grooves is two, which are symmetrically distributed on both sides of the suction cup hole.

[0018] As a further improvement of one embodiment of the present invention, each material gripping assembly has four vacuum suction cups, which are distributed in a rectangular shape on the lifting plate.

[0019] The above technical solution has the following beneficial effects: by using a vacuum suction cup with a corrugated tube structure, which has elasticity and works in conjunction with the pressure plate, the vacuum suction cup can be pressed down to the maximum extent without damaging the product inside the packaging, thereby improving the suction capacity of the vacuum suction cup to the product and overcoming the suction problem caused by uneven product surfaces.

[0041] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0042] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model. Example

[0043] See Figures 1-3 As shown, a spider-hand loading mechanism is installed on a packaging production line to achieve efficient, stable, and precise gripping and placement of product 5. The mechanism includes a fixed frame 1 and a spider-hand robot 2 mounted on the fixed frame 1. The spider-hand robot 2 serves as the execution body and is equipped with a carrier plate 3, which carries at least one set of gripping components 4. These gripping components 4 are the core part of the mechanism to achieve the product gripping function.

[0044] Specifically, the material gripping assembly 4 includes a vertical cylinder 41, which serves as a power source, with its piston end securely connected to a lifting plate 42. Driven by the vertical cylinder 41, the lifting plate 42 can move vertically up and down. Several vacuum suction cups 43 with corrugated structures are arranged around the lower part of the lifting plate 42. These vacuum suction cups 43 not only possess excellent adsorption performance, but their corrugated structure also gives them good elasticity, ensuring good adhesion and adsorption force when gripping the product 5.

[0045] To further enhance the adsorption effect of the vacuum suction cup 43 and prevent damage to the product 5 during gripping, an adjustable-height pressure plate 44 is specially provided below the lifting plate 42. The lower end face of this pressure plate 44 is carefully designed to be slightly higher than the lower end face of the vacuum suction cup 43, thus creating a height difference. When the vacuum suction cup 43 contacts and adsorbs the product, the pressure plate 44 can limit the distance that the vacuum suction cup 43 can continue to press down, preventing damage to the product due to excessive squeezing. At the same time, this design also allows the vacuum suction cup 43 to maintain a certain pre-tightening force when adsorbing the product, further improving the stability and reliability of adsorption.

[0046] In practical applications, this spider-hand loading mechanism, through the precise positioning of the spider-hand robot 2 and the flexible gripping of the material-grabbing component 4, can quickly and accurately transfer products 5 from one place to another, such as from the packaging area on the production line to the packaging container. Throughout the process, the corrugated vacuum suction cup 43 and the adjustable-height pressure plate 44 work together to ensure the integrity of the product inside the packaging while maximizing the suction capacity of the vacuum suction cup 43, effectively overcoming the suction problem caused by uneven product surfaces.

[0047] Specifically, the compression stroke of the vacuum suction cup 43 is designed to be greater than the height difference between the pressure plate 44 and the lower end face of the vacuum suction cup 43. This design ensures that in actual gripping operations, even if the product surface is uneven or has a certain thickness variation, the vacuum suction cup 43 can make adaptive adjustments through its own compression stroke.

[0048] Each gripping assembly 4 has four vacuum suction cups 43 arranged in a rectangle on the lifting plate 42. This layout ensures that the vacuum suction cups 43 are evenly stressed when gripping products, improving the stability and reliability of the gripping process. The rectangular arrangement also facilitates adjustment and optimization based on the shape and size of the product to meet different gripping needs. Simultaneously, the four vacuum suction cups 43 working together generate stronger suction force, effectively overcoming the gripping challenges caused by uneven product surfaces or material differences, further enhancing the performance and efficiency of the loading mechanism.

[0049] In this embodiment, two independent gripping components 4 are provided on the carrier plate 3. These two sets of gripping components 4 are structurally independent and can perform gripping tasks independently. Each set of gripping components 4 is controlled by an independent air path, which means that they can perform lifting, adsorption, and other operations independently without interfering with each other. The independent air path design not only improves the flexibility and response speed of the gripping components 4, but also enhances the stability and reliability of the entire loading mechanism. In practical applications, the working state of the two sets of gripping components 4 can be flexibly adjusted according to production needs to achieve efficient and accurate product loading.

[0050] In this embodiment, a first adjustment groove 31 is provided on the carrier plate 3. This adjustment groove is an elongated structure extending in a specific direction, providing the possibility for adjusting the position of the vertical cylinder 41. The vertical cylinder 41 is located below the carrier plate 3 and is not directly fixed, but is locked to the carrier plate 3 by bolts passing through the first adjustment groove 31. This design allows the position of the vertical cylinder 41 on the carrier plate 3 to be adjusted according to actual needs to adapt to the gripping requirements of products of different sizes or shapes. By loosening the bolts, moving the vertical cylinder 41 to the appropriate position, and then locking it again, quick adjustment can be achieved, enhancing the flexibility and versatility of the loading mechanism.

[0051] Similarly, the lifting plate 42 is provided with a suction cup hole 421 for the vacuum suction cup 43 to be inserted. The size of the suction cup hole 421 is larger than that of the vacuum suction cup 43, allowing the vacuum suction cup 43 to move within the suction cup hole 421. A second adjustment groove 422 is provided around the suction cup hole 421. This adjustment groove has an elongated structure and is used to limit the range of movement of the vacuum suction cup 43. A mounting plate 45 is provided on the vacuum suction cup 43, and the mounting plate 45 is fixedly connected to the vacuum suction cup 43. During installation, bolts pass through the second adjustment groove 422 and are locked to the mounting plate 45. By loosening or tightening the bolts, the position of the vacuum suction cup 43 on the lifting plate 42 can be adjusted to meet the gripping needs of different products, improving the flexibility and applicability of the loading mechanism.

[0052] Preferably, there are two second adjustment slots 422, which are symmetrically distributed on both sides of the suction cup hole 421. This layout design makes the position adjustment of the vacuum suction cup 43 on the lifting plate 42 more stable and balanced, and can more effectively adapt to the gripping needs of products of different sizes or shapes, improving the flexibility and adjustment accuracy of the loading mechanism.

[0053] In this embodiment, the pressure plate 44 is provided with several screws 46, which are evenly distributed to achieve a detachable connection between the pressure plate 44 and the lifting plate 42. The lifting plate 42 is provided with corresponding through holes for the screws 46 to be inserted. The size of the through holes matches the screws 46 to ensure that they can pass through smoothly. After the screws 46 pass through the through holes, they are positioned and secured to the lifting plate 42 by nuts. This design not only facilitates the installation and disassembly of the pressure plate 44 but also allows for adjustment of the height of the pressure plate 44 according to actual needs, thereby flexibly adapting to the gripping requirements of different products and improving the versatility and practicality of the loading mechanism.

[0054] This invention employs a vacuum suction cup 43 with a corrugated tube structure, utilizing its unique elasticity to cleverly cooperate with the pressure plate 44. In actual operation, when the vacuum suction cup 43 contacts the surface of the product 5, the corrugated tube structure automatically adjusts its shape to adapt to the unevenness of the product surface. Simultaneously, the pressure plate 44 limits the downward pressure distance of the vacuum suction cup 43, ensuring maximum compression of the corrugated tube without damaging the product inside the packaging, thereby enhancing the suction capacity of the vacuum suction cup 43. This design effectively overcomes the suction problem caused by uneven product surfaces, improving the stability and reliability of the loading mechanism.
