[0001] The utility model relates to the technical field of packaging equipment, in particular to a bag feeding component with a posture adjustment function. Background Art

[0002] In the traditional operation process of bag-feeding packaging machines, bag picking is a key link. It usually involves accurately and quickly taking out pre-made empty bags from the bag bin and conveying them to the next processing step, such as the filling area.

[0003] However, since the bag-feeding packaging machine adopts swing-type feeding, the posture of the bag will be converted from horizontal to vertical during this process. This conversion poses a challenge for some bags with soft materials, uneven thickness or easy deformation, such as composite film bags, thin plastic bags or specific paper bags.

[0004] At the moment of conversion, the bag may rub, twist, fold or collapse at the bottom. These deformations not only affect the subsequent precise filling process, but may also lead to incomplete filling and poor sealing, and may also affect the appearance quality of the product and the consumer experience. In serious cases, it may even damage the sealing of the packaging, affecting the shelf life and safety of the product. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Embodiment 1, as Figure 1-Figure 2 As shown, the present embodiment provides a bag feeding assembly with a posture adjustment function, a bag feeding assembly with a posture adjustment function, including a bag bin, a bag taking mechanism and an adjustment mechanism. The bag bin is mounted on a workbench, and the main structure is made of aluminum alloy to take into account both lightness and strength. The bag bin consists of a base and two baffles vertically arranged on the base, the two baffles are arranged parallel to each other, and the space formed in the middle is used to store bags to be taken, and a discharge port is provided on the base.

[0024] The bag taking mechanism is arranged at the lower side of the discharge port. Along the height direction of the discharge port, the bag taking mechanism has an adsorption part and a telescopic part connected in sequence. The adsorption part is used to adsorb the material in the bag bin. The adsorption part can be a platform arranged parallel to the discharge port. The surface of the platform is integrated with evenly distributed vacuum adsorption holes. Each hole is connected to an efficient vacuum system. By precisely controlling the vacuum pressure, the adsorption force can be adjusted according to the different materials and weights of the materials, so as to achieve precise control without excessive adsorption to cause deformation of the bag body and without insufficient adsorption force to cause falling off. The telescopic part is made of high-strength and lightweight material, with a built-in driving device, such as a servo motor or a cylinder. There is a bag taking area between the adsorption part and the discharge port, and the telescopic part can be telescoped up and down relative to the discharge port.

[0025] The adjustment mechanism and the bag taking mechanism are arranged on the same side and are located at the lower side of the bag taking mechanism. The adjustment mechanism has a swing arm and a positioning platform. The swing arm can swing left and right relative to the material discharge port. A servo motor or a stepper motor can be installed at the other end of the swing arm and connected to the swing arm through a gear set or a synchronous belt. The motor is controlled by a PLC or a computer program. According to the preset instructions, the rotation angle and speed of the motor are accurately controlled, thereby driving the swing arm to achieve a predetermined left and right swing. The positioning platform is connected to the swing arm in a swinging manner so that the positioning platform can swing up and down relative to the material discharge port. The positioning platform can be connected to the swing arm through a rotating joint. This joint can bear the weight of the platform and allow it to rotate freely around an axis. The axis usually uses a high-load bearing to reduce friction and ensure the smoothness of rotation. On the other side of the swing arm, a driving device is installed. The driving device can be a servo motor or a hydraulic / pneumatic cylinder, etc. The motor or cylinder is connected to the other end of the swing arm through a transmission mechanism (such as a gear set, chain or synchronous belt drive), so that the swinging action of the swing arm can be transmitted to the positioning platform. There is a positioning area between the positioning platform and the material discharge port.

[0026] When feeding bags, the suction part first sucks the bag out of the bag bin. After successful suction, the telescopic part telescopes downward, driving the suction part to carry the bag from the initial bag taking area to the positioning area smoothly. When the bag reaches the top of the positioning area, the suction force gradually weakens and is released in time, so that the bag is placed smoothly on the positioning platform. Finally, the positioning platform swings left and right through the coordinated action of the swing arm, and also rotates up and down, thereby forming an arc path in the positioning area to guide the bag and complete the posture adjustment.

[0027] Embodiment 2, on the basis of the above embodiment, in order to optimize the path and posture control of the bag during the transfer process, the bag picking area and the positioning area have an overlapping area, and the telescopic part is interspersed in the overlapping area along the height direction of the overlapping area. This overlapping area is essentially a transition zone between the two stages of bag picking and positioning, which ensures the continuity and stability of the bag during the movement. The telescopic part is designed to be interspersed in the overlapping area, which means that it has the ability to cross the bag picking and positioning platforms in the vertical direction. The advantage of this design is that when the bag moves from the bag picking area to the positioning area, the telescopic part can adjust its length in time, which not only supports the bag, but also avoids interference in the overlapping area, ensuring a smooth transition of the material.

[0028] In specific implementation, a vertical channel can be opened in the middle area of ​​the positioning platform. This channel smoothly transitions with the surface of the positioning platform to ensure that no protrusions or obstacles are formed. The main purpose of this channel is to allow the telescopic part to directly pass through the middle of the platform instead of bypassing it during the platform swing process, especially when operating in the overlapping area, so as to avoid any physical interference with the platform. The benefit of this is that the smoothness and efficiency of the entire system operation are improved, the complexity of the mechanical design is reduced, and the movement path of the telescopic part is more direct and concise.

[0029] Embodiment 3, based on the above embodiment, a plurality of adsorption points are arranged on the adsorption part, and the plurality of adsorption points are located in the same plane, and the side of the positioning platform close to the discharge port is parallel to the plane where the plurality of adsorption points are located. Specifically, the surface of the adsorption part not only has a large single adsorption area, but also has a plurality of dispersed and evenly arranged adsorption points. These adsorption points are located in the same plane, which means that they are at the same height in the direction perpendicular to the discharge port, ensuring a balanced distribution of gripping force on the material. In this way, the number and distribution of adsorption points can be adjusted for material bags of different sizes and shapes, so that the material can be more firmly controlled and carried without damaging it.

[0030] The side of the positioning platform close to the discharge port is specially designed to be parallel to the plane where the above-mentioned adsorption points are located. Such alignment is not only for visual neatness, but also for precise positioning of operations. When the adsorption part carries the material to the positioning platform, the material can slide smoothly due to the parallel correspondence between the adsorption point and the platform, reducing friction and unnecessary movement, ensuring the stability of the material during the transfer process, especially for bags that are easily deformed or sensitive materials, reducing the risk of damage.

[0031] For example, when handling a batch of thin and soft plastic bag materials, the adsorption unit may pre-set 3-4 points for activation, evenly distributed, to avoid excessive concentrated stress points on the bag and cause deformation. When the adsorption unit moves the material to the positioning platform, the edge of the platform is parallel to the plane of the adsorption point, so the material can slide smoothly into the preset groove or plane on the positioning platform. The whole process is almost shake-free, reducing the distortion or damage of the bag caused by friction and improving the accuracy of placement.

[0032] Embodiment 4, based on the above embodiment, the adsorption part has a first vertical distance relative to the discharge port, the positioning platform has a second vertical distance relative to the discharge port, and the maximum value of the first vertical distance is greater than the maximum value of the second vertical distance. Specifically, it is assumed that in operation, the adsorption part rises from below the discharge port and absorbs the material at a certain distance. This first vertical distance is greater than the second vertical distance, which means that when the adsorption part rises with the material and is ready to be transferred to the positioning platform, there is enough space for the material bag to unfold, avoiding deformation or damage that may occur due to squeezing in a small space. When the material is transferred to the positioning platform, the lower position of the platform just matches the falling point of the material, so that the material can be smoothly moved to the positioning platform without hovering, pausing or falling sharply in the air, reducing the impact.

[0033] This distance setting reduces the impact of height differences during material transfer, and is especially friendly to fragile or sensitive materials, such as thin plastic bags, paper bags, etc. At the same time, this design also optimizes the mechanical motion path, making the overall movement smoother, improving efficiency, reducing energy consumption and wear, and improving the stability of automated operations.

[0034] Embodiment 5, based on the above embodiment, the positioning platform has a material picking end, and a clamping groove is opened on the material picking end, and the clamping groove is located in the outside world, wherein the outside world refers to the space outside the overlapping area, and the front end of the positioning platform is specially designed as the material picking end, which is the intersection point where the material is finally positioned and taken away by other equipment such as a robotic arm or other automated processes.

[0035] At the reclaiming end, a clamping groove is specially designed to ensure that the material can stay in the designated position more stably after being transferred from the adsorption part to the positioning platform, waiting for further processing. The shape and size of the clamping groove are customized according to the typical characteristics of the material to ensure that the material can be effectively fixed without causing compression or damage.

[0036] It is worth noting that the clamping slot is located in the "outside", that is, the space outside the overlapping area. The "outside" here refers to the overlapping area between the bag picking area and the positioning area, indicating that the clamping slot is not in this most dynamic interactive operation area, but is located in a relatively static area dedicated to the final positioning of the material. This layout avoids interference during the material transfer process and also provides a safe static positioning point for subsequent fixation.

[0037] During operation, after the adsorption part takes out the material from the discharge port, the material is accurately sent to the positioning platform through the up and down movement of the telescopic part and the cooperation of the swing arm. When the material reaches the material taking end, the clamping groove just receives part of the edge or specific part of the material, so that it waits for the next operation. This design reduces the sliding of the material during the final positioning, improves the stability and accuracy of the automated process.

[0038] Embodiment 6, based on the above embodiment, the two ends of the clamping groove have support parts, and the support parts are arranged in the overlapping area. Specifically, the clamping groove is arranged along the material taking end, and the shape is customized according to the contour and size of the material to provide the best support surface. The inner wall of the groove can be designed with fine texture or slight protrusion to increase friction without damaging the material, ensuring that the material stays stably in the groove.

[0039] At both ends of the clamping groove, the newly added support parts are not simply used as physical barriers, but are designed as auxiliary transition structures. The support parts are semicircular or inclined, which can smoothly guide the material from the adsorption part to the final position of the positioning platform, while avoiding scratches caused by sharp angles or right angles.

[0040] The support part is arranged inside the overlapping area, that is, the part where the bag taking area overlaps with the positioning area. This ensures that during the transfer process of the material from dynamic adsorption to positioning, the support part coordinates with the telescopic part or the swinging action to reduce interference while providing continuous support force.

[0041] Embodiment 7, based on the above embodiment, the positioning platform has a swing end, and an avoidance groove is opened on the swing end, and the two ends of the avoidance groove are respectively located on both sides of the telescopic part. Specifically, the swing end of the positioning platform is specially provided with an avoidance groove, and the position and shape of the avoidance groove are precisely calculated to adapt to the path of the telescopic part when it swings. The opening direction and size of the avoidance groove ensure that it does not interfere with the movement of the telescopic part, especially when the platform is in the overlap area at the maximum swing amplitude.

[0042] The two ends of the avoidance groove are respectively designed on both sides of the telescopic part, which not only avoids direct collision during swinging, but also forms a guide in the structure, so that the telescopic part can be more stable and controlled along the trajectory of the groove when moving.

[0043] In actual operation, when the positioning platform swings, the avoidance groove design allows the telescopic part to move freely up and down in the groove without obstruction. In this way, even when the platform swings to the maximum extent, the telescopic part will not be blocked by colliding with the platform, ensuring the continuity of movement and the stability of the mechanical components.

[0044] Embodiment 8, on the basis of the above embodiment, the swing of the positioning platform has an anti-slip portion, and the upper end of the anti-slip portion faces the material picking end of the positioning platform. Specifically, an anti-slip portion is added to the swing end of the positioning platform. The anti-slip portion is specially designed with friction enhancing materials or textures, such as rubber gaskets, anti-slip coatings, and its surface is treated into a corrugated or convex dot array to increase the friction when in contact with the material and prevent sliding.

[0045] The upper end of the anti-skid part is designed to point or tilt toward the material-retrieving end of the positioning platform, i.e., the final material placement area. This layout ensures that during the swinging process, no matter how the platform rotates, the material can be guided and supported upward by the anti-skid part to prevent slipping and dislocation.

[0046] When the positioning platform swings, the inclined design of the anti-skid part can effectively offset the sliding tendency of the material caused by gravity. Especially when the platform swings at a large angle, the upper end of the anti-skid part provides continuous friction to help the material stay in place.

[0047] The presence of the anti-slip part, especially its design toward the material-retrieving end, enables the material to remain stable even during dynamic swinging, helps with precise positioning, provides an accurate starting point for subsequent steps such as filling and sealing, and improves work efficiency and quality.

[0048] Working principle:

[0049] When the equipment is in use, the control system starts first, activating the adsorption part to accurately adsorb the material in the bag bin. After the adsorption is firm, the telescopic part is activated by the drive device, and the telescopic movement is precisely controlled in the vertical direction to guide the adsorption part to carry the material from the bag picking area to the positioning area smoothly. When the material reaches the top of the positioning area, the control system adjusts the adsorption force release in time to make the bag land smoothly on the positioning platform. This process avoids impact and sliding. At this time, the swing arm swings left and right under the guidance of the control system to adjust the positioning platform to the optimal position to receive the bag. The robotic arm or clamping mechanism intervenes to assist in fixing the bag to ensure its stability on the platform. The control system further guides the swing of the platform and realizes the posture adjustment of the bag through the coordinated operation of the robotic arm. At this stage, the fine-tuning kinetic energy of the platform ensures that the bag reaches a precise posture to meet the subsequent process requirements.
