Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic product packing, specifically to an automated product packing device. Background Technology
[0002] In current enterprise production and operation processes, the packaging of valve guide products after inspection has long relied on manual operation. With the increasing urgency of enterprise automation upgrades, companies have attempted to introduce robotic automated packaging technology to improve production efficiency and reduce labor costs. However, in actual implementation, numerous thorny problems have been encountered, making it difficult to successfully achieve automated packaging, and enterprises still face significant labor cost pressures.
[0003] During the packing process, rust-proof bags need to be placed over corrugated cardboard boxes to protect valve guides from corrosion. However, when the rust-proof bags are placed over the boxes, they are in a loose state, lacking the necessary tightness and stability. This loose state makes the products prone to shifting during packing. Products that were originally arranged in a certain order and according to rules quickly become disordered after being placed in loose rust-proof bags and easily deformable corrugated cardboard boxes. For robotic automated packing systems, this disordered state cannot be effectively identified and handled because it relies on a preset program for orderly product arrangement. Therefore, the loose state of the rust-proof bags directly disrupts the orderly environment necessary for automated packing, preventing the robot from performing continuous and stable automated packing operations according to the predetermined program. Utility Model Content
[0004] This application provides an automated product packing device that can solve the technical problem in the prior art where, during the packing process, loose bags and easily deformable corrugated paper do not provide limited restraint on the product, making the product easily become disordered and destroying the orderly environment necessary for automated packing. This prevents the robot from performing continuous and stable automated packing operations according to the predetermined program.
[0005] This application provides an automated product packing device, including:
[0006] The packing assembly includes a placement box with a top opening and a support bag liner that is movably embedded in the opening of the placement box. The outer wall of the support bag liner is spaced a certain distance from the inner wall of the placement box. A pressure bag frame is movably fitted around the outer periphery of the support bag liner for engaging with the opening of the placement box.
[0007] The fixing component includes a negative pressure mechanism disposed at the bottom of the placement box, and the bottom of the placement box has an absorption hole for communicating with the negative pressure mechanism.
[0008] In one embodiment, the placement box includes an outer box and an inner box located inside the outer box.
[0009] In one embodiment, the bottom of the outer casing is spaced a certain distance from the bottom of the inner casing.
[0010] In one embodiment, the absorption hole includes a connection hole opened at the bottom of the outer casing and a plurality of negative pressure holes opened at the bottom of the inner casing.
[0011] In one embodiment, the negative pressure mechanism includes a negative pressure fan and a negative pressure pipe connected to the negative pressure fan, with the free end of the negative pressure pipe connected to the connection hole.
[0012] In one embodiment, the top of the inner box protrudes from the top of the outer box. In another embodiment, the cross-sectional area of the pressure bag frame is larger than the cross-sectional area of the inner box, and it engages with the outer periphery of the end of the inner box that protrudes from the top of the outer box.
[0013] In one embodiment, one end of the inner liner of the support bag is embedded in the placement box, and the other end extends out of the placement box.
[0014] In one embodiment, the inner liner of the support bag is axially continuous.
[0015] In one embodiment, the bottom of the placement box is provided with a plurality of connecting ears for connecting to an external production line, the connecting ears extending horizontally and being disposed opposite to each other on both sides of the bottom of the placement box.
[0016] The beneficial effects of the technical solutions provided in this application include:
[0017] By setting up a placement box, it can temporarily replace the corrugated cardboard box during the packing process, accommodating rust-proof bags and products to be packed. It provides a stable holding space for the rust-proof bags and products to be packed, avoiding disorder of the products to be packed. By setting up a negative pressure mechanism and bag pressing frame, the posture of the already placed rust-proof bags can be fixed to prevent twisting and deformation. At the same time, the bag support liner can also initially unfold the rust-proof bags, making it easier to put the rust-proof bags on. It effectively avoids the shortcomings of insufficient strength of corrugated cardboard boxes and soft rust-proof bags that are not conducive to accurate positioning. It successfully realizes the improvement of automated packing of products to be packed and enhances the automation performance of the packing process. Attached Figure Description

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0023] This application provides an automated product packing device that solves the technical problem in the prior art where, during the packing process, loose bags and easily deformable corrugated paper do not provide adequate restraint for the product, causing the product to easily become disordered and disrupting the orderly environment necessary for automated packing. This prevents the robot from performing continuous and stable automated packing operations according to a predetermined program.
[0024] The automated product packing device in this application includes a packing component and a fixing component. The packing component is one of the core parts of the device and adopts a rigid structure design. During the packing operation, the rust-proof bag 8 is fitted onto the packing component. The packing component can temporarily replace the corrugated cardboard box and undertake the important task of accommodating the rust-proof bag 8 and the product to be packed. Since the corrugated cardboard box has low strength and is easily deformed, it is difficult to maintain a stable shape during automated operation. However, the packing component, with its rigidity, can always maintain a fixed shape and structure, providing a stable and reliable space for the rust-proof bag 8 and the product, avoiding disorder of the product, and providing a stable automated packing environment for the robot. The fixing component is set on the packing component and can fix the posture of the rust-proof bag 8, preventing it from shifting and deforming during the packing process, further improving the convenience of packing.
[0025] Specifically, Figure 1 This is an exploded view of an automated product packing device provided in an embodiment of this application, as shown below. Figure 1 As shown, the packing assembly in this application includes a top-opening placement box 1 and a support bag liner 2 that is movably embedded in the opening of the placement box 1. The placement box 1 is configured to be the same shape as the corrugated cardboard box, and is a cuboid structure with a top opening. The cross-sectional area of the inner wall of the placement box 1 is slightly larger than that of the corrugated cardboard box, so that the outer wall of the support bag liner 2 is spaced a certain distance from the inner wall of the placement box 1, which facilitates the flexible entry and exit of the support bag liner 2. In one possible embodiment, the gap between the outer dimension of the support bag liner 2 and the inner wall of the placement box 1 is 1.2±0.5mm. During the packing process, the rust-proof bag 8 is first fitted onto the outer periphery of one end of the support bag liner 2, and then the support bag liner 2 is embedded inside the support bag liner 2. The rust-proof bag 8 is located between the placement box 1 and the support bag liner 2, realizing the rapid fitting of the rust-proof bag 8.
[0026] The inner liner 2 of the support bag is movably fitted with a bag-pressing frame 3 for engaging with the opening of the placement box 1. The bag-pressing frame 3 is a square frame. The depth of the placement box 1 is less than the depth of the rust-proof bag 8. After the rust-proof bag 8 is fitted, the opening of the rust-proof bag 8 is turned outwards, and the bag-pressing frame 3 presses on the turned-out edge of the rust-proof bag 8 to fix the fitted state of the rust-proof bag 8. During the process of fitting the rust-proof bag 8, the bag-pressing frame 3 can be fitted onto the outer circumference of the inner liner 2 first, or it can be fixed by passing through the inner liner 2 after the rust-proof bag 8 is fitted. It can be operated according to the actual situation.
[0027] The fixing component includes a negative pressure mechanism 4 located at the bottom of the placement box 1. The bottom of the placement box 1 has absorption holes for communicating with the negative pressure mechanism 4. The negative pressure mechanism 4 uses negative pressure to fix the posture of the rust-proof bag 8. After the rust-proof bag 8 is installed, the inner liner 2 is removed to facilitate packing. At this time, the rust-proof bag 8 is only fixed at the top by the bag-pressing frame 3, and the bag inside the placement box 1 remains free. Therefore, when the negative pressure mechanism 4 is activated, it can generate a negative pressure effect through these absorption holes, thereby effectively fixing the posture of the rust-proof bag 8. Under the action of negative pressure, the rust-proof bag 8 can fit tightly against the bottom of the placement box 1, preventing it from shaking or shifting, thus facilitating subsequent packing.
[0028] Furthermore, Figure 2 A cross-sectional view of a product automated packing device provided in this application embodiment, showing the placement of box 1. Figure 2 As shown, the box 1 includes an outer box 101 and an inner box 102 located inside the outer box 101. The outer box 101 and the inner box 102 can be detachably connected or fixedly formed as one unit. This application does not impose any specific limitations. In one possible embodiment, the size of the inner box 102 is consistent with the internal size of the corrugated cardboard box. To avoid scratching the rust-proof bag 8, the inner box 102 is preferably made of nylon material, while the outer box 101 is preferably made of stainless steel material.
[0029] Further details can be found here. Figure 2 The volume of the outer box 101 is not specifically limited, but it must be larger than the volume of the inner box 102. The bottom of the outer box 101 and the bottom of the inner box 102 are separated by a certain distance, which provides the necessary space for the installation and operation of subsequent components such as the negative pressure mechanism 4. This ensures that the components do not interfere with each other, thus guaranteeing the compactness and stability of the entire device structure. The space also plays a certain buffering role, reducing the impact of external vibrations and other factors on the inner box 102 and its internal products.
[0030] The absorption holes include connection holes 5 at the bottom of the outer casing 101 and several negative pressure holes 6 at the bottom of the inner casing 102. The negative pressure mechanism 4 includes a negative pressure fan and a negative pressure pipe 401 connected to the negative pressure fan. The free end of the negative pressure pipe 401 is connected to the connection hole 5. The negative pressure fan is the power source of the entire negative pressure mechanism 4. Generally, it generates negative pressure by forming a strong airflow inside the device through high-speed rotating fan blades. The negative pressure fan is a commonly used component in this field, and its specific structure and working mechanism will not be described in detail here. One end of the negative pressure pipe 401 is connected to the negative pressure fan, and the other end is mechanically connected to the connection hole 5. There are multiple negative pressure holes 6, which are evenly distributed on the bottom plate of the inner casing 102. The negative pressure is used to fix the rust-proof bag 8 through the negative pressure holes 6.
[0031] As an optional embodiment, all inner walls of the outer box 101 and all inner walls of the inner box 102 are spaced apart by a certain distance (i.e., the bottom wall and the four side walls). Negative pressure holes 6 are evenly distributed on the four side walls and the bottom wall of the inner box 102. These evenly distributed negative pressure holes 6 can simultaneously apply adsorption force to the rust-proof bag 8 from multiple directions and positions. Regardless of the posture of the rust-proof bag 8 within the box, it ensures that all parts of the bag are stably adsorbed, thus tightly adhering to the inner wall of the inner box 102. This omnidirectional fixing method greatly enhances the stability of the rust-proof bag 8, effectively preventing wrinkles and displacement during packing.
[0032] Further details can be found here. Figure 2 The top of the inner box 102 protrudes a certain distance from the top of the outer box 101 to engage with the bag-pressing frame 3. The cross-sectional area of the bag-pressing frame 3 is larger than that of the inner box 102, and it engages with the outer periphery of the end of the inner box 102 that protrudes from the top of the outer box 101. The protruding part of the inner box 102 provides a dedicated engagement position for the bag-pressing frame 3, allowing the bag-pressing frame 3 to be accurately positioned and fixed on the inner box 102. The bag-pressing frame 3 directly contacts the rust-proof bag 8, and therefore, it is also made of nylon. Through large-area contact and tight engagement, it can effectively limit the movement of the top of the rust-proof bag 8, preventing the rust-proof bag 8 from moving upward or deforming due to external forces during the packing process. At the same time, since the engagement structure between the bag-pressing frame 3 and the inner box 102 is simple and clear, operators can quickly and accurately install and disassemble it, which also greatly improves the efficiency of the packing work.
[0033] Furthermore, in order to achieve product lightweighting and reduce manufacturing costs, the inner liner 2 is an axially continuous cuboid, with one end of the inner liner 2 embedded in the placement box 1 and the other end extending out of the placement box.
[0034] Further details can be found here. Figure 2 The bottom of the placement box 1 is provided with several connecting ears 7 for connecting to external production lines. The connecting ears 7 extend horizontally and are positioned opposite each other on both sides of the bottom of the placement box 1. Automated product packing is generally completed automatically on the production line. The opposing connecting ears 7 on both sides can form a balanced support structure, keeping the placement box 1 stable on the production line. During the automated packing process, the conveying equipment, robotic arms, etc. on the production line will apply various forces to the placement box 1. The connecting ears 7 on both sides can effectively resist these forces and prevent the placement box 1 from tilting or shaking. The connecting ears 7 can be of the snap-fit type, with corresponding mating parts arranged on the production line, or they can be of the threaded connection type, with mating threaded holes arranged at the relative positions of the connecting ears 7 and the production line. The connection methods are diverse and are not specifically limited in this application.
[0035] The automated product packing device in this application is used as follows: the rust-proof bag 8 is fitted over the inner liner 2 and both are embedded into the box 1 to initially flatten the rust-proof bag 8. Then, the opening of the rust-proof bag 8 is turned outward, and the bag pressing frame 3 is passed through the inner liner 2 and fitted around the outer periphery of the protruding part of the inner box 102 to fix the position of the opening of the rust-proof bag 8. The negative pressure mechanism 4 is activated to fix the negative pressure, and the inner liner 2 is pulled out to carry out the packing work. Finally, the rust-proof bag 8 and the packed products are transferred together into the corrugated carton.
