Technical Field

[0001] This utility model relates to the field of packaging bag machinery automation technology, specifically to an automatic packaging bag feeding device. Background Technology

[0002] In packaging production lines of industries such as food, pharmaceuticals, and chemicals, automated feeding of packaging bags is a crucial step. Traditional feeding devices often employ linear or single-station material handling methods, which have the following drawbacks: First, the material handling, inspection, and transfer processes cannot be carried out continuously, resulting in low production efficiency; second, when the material in a single hopper is depleted, the machine must be stopped for manual replacement, leading to a shutdown of the entire line, low equipment utilization, and difficulty in meeting the demands of modern continuous production.

[0003] Therefore, there is an urgent need for an automatic bag feeding device that can achieve continuous, efficient, and automated operation, and has high reliability and flexible production capabilities. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic feeding device for packaging bags.

[0005] The technical solution of this utility model is as follows: it includes a main workbench, a hopper platform fixedly installed on the main workbench, a main hopper arranged on the hopper platform, and a rotary conveyor unit set below the main hopper.

[0006] The rotary conveying unit includes a rotatable first rotary platform, which has multiple packaging bag support positions circumferentially arranged. The support positions rotate with the first rotary platform and pass sequentially through the main loading station, the inspection station and the material transfer station.

[0007] The main feeding station is located below the main material silo, and the main feeding station is equipped with a liftable adsorption mechanism.

[0008] When any of the support positions rotates to the main feeding position, the adsorption mechanism rises to contact the packaging bag at the bottom of the main material bin and completes adsorption, then descends and releases the packaging bag onto the support position.

[0009] A further technical solution is as follows: the adsorption mechanism includes a lifting component disposed below the support position and a vacuum suction cup mounted on the lifting component; the support position is provided with a through hole for the vacuum suction cup to pass through; the main loading station is provided with a lifting drive device for driving the lifting component to move up and down.

[0010] A further technical solution is as follows: the rotary conveying unit also includes a second rotary platform driven by a servo motor and rotating synchronously with the first rotary platform; each of the support positions is provided with an adsorption mechanism; wherein the lifting assembly includes a lifting plate and a lifting rod fixed thereto, the lifting rod is connected to the second rotary platform through a linear bearing and moves up and down relative to it; when the bottom end of each lifting rod rotates with the second rotary platform to the main loading position, it sequentially docks with the output end of the lifting drive device.

[0011] A further technical solution is that two packaging bag support positions are arranged side by side on the first rotating platform corresponding to the main feeding station, the inspection station and the material transfer station.

[0012] A further technical solution is that two main material bins are set up on the material bin platform above the main material loading station.

[0013] A further technical solution is that the material hopper platform is also provided with two sets of parallel buffer bins, and two packaging bag support positions are arranged in parallel below the two sets of buffer bins on the first rotating platform to form a material loading standby station.

[0014] A further technical solution is as follows: a lifting drive device is provided on the main workbench below the material loading standby station, with its output end pointing vertically upward and corresponding to the lifting plate below the support position through which it rotates.

[0015] A further technical solution is that a detection unit is provided above the detection station, and the detection unit includes a visual recognition component for identifying the front and back of the packaging bag and the material number.

[0016] A further technical solution is as follows: a material transfer unit is provided above the material transfer station, the material transfer unit includes a dual-axis drive module and a material handling end effector; the dual-axis drive module includes an X-axis linear module and a Z-axis linear module, and the material handling end effector is installed on the output end of the Z-axis linear module.

[0017] A further technical solution is as follows: the main material hopper is provided with multiple vertically arranged positioning baffles around its perimeter, which together enclose a space for holding stacked packaging bags; the main material hopper is also provided with a pressure plate for applying downward pressure to the stacked packaging bags.

[0018] The beneficial technical effects of this utility model are:

[0019] (1) By setting up a rotatable first rotating platform and multiple support positions distributed around the circumference, the packaging bag can be continuously operated in a production line between the main feeding station, the inspection station and the material transfer station. The material picking, inspection and material transfer processes are carried out simultaneously, eliminating the waiting time between processes and greatly shortening the production cycle.

[0020] (2) The adsorption mechanism is distributed below each support position and concentrated in the main feeding position to achieve lifting. This not only realizes the material picking operation of the adsorption mechanism in the main feeding position, but also simplifies the structure and reduces costs.

[0021] (3) By setting up two support positions, two main material bins and two detection units in parallel, two packaging bags can be processed in parallel at the same time, which can multiply the feeding efficiency per unit time, and is especially suitable for high-efficiency and large-volume production needs.

[0022] (4) By setting up a backup feeding station and a corresponding buffer bin, the system can automatically switch to the buffer bin to continue feeding when the material in the main bin is used up, thus achieving non-stop operation and effectively avoiding machine downtime due to material change, which greatly improves the overall operating efficiency and equipment utilization of the automated production line.

Detailed Implementation

[0031] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0032] like Figures 1 to 3 As shown, the automatic packaging bag feeding device of this utility model includes a main workbench 100, a material hopper platform 200 fixedly installed on the main workbench 100, a main material hopper 300 arranged on the material hopper platform 200, and a rotary conveying unit 400 arranged below the discharge hopper.

[0033] The main material hopper 300 is provided with multiple vertically arranged positioning baffles 301 around its perimeter; each positioning baffle 301 is fixedly installed on the material hopper platform 200 and together they enclose a space for holding stacked packaging bags; the main material hopper 300 is also provided with a pressure plate 302 for applying downward pressure to the stacked packaging bags.

[0034] like Figure 4 The rotary conveying unit 400 includes a servo motor 410, a first rotary platform 420, and a second rotary platform 430. The servo motor 410 is fixed to the main worktable 100, and its output end is connected to the first rotary platform 420 and the second rotary platform 430 for driving them to rotate synchronously around the same vertical axis. The first rotary platform 420 and the second rotary platform 430 are arranged parallel to each other vertically and at intervals.

[0035] like Figure 5 and Figure 6 The first rotating platform 420 has multiple packaging bag support positions 421 evenly arranged along its circumference. Each support position 421 rotates with the first rotating platform 420 and passes sequentially through the main loading station S1, the inspection station S2, and the transfer station S3. The main material hopper 300 is located above the main loading station S1. Above the first rotating platform 420, corresponding to the inspection station S2 and the transfer station S3, there are inspection units 500 and transfer units 600. The inspection unit 500 is used to identify the status of the packaging bags located at the inspection station S2, and the transfer unit 600 is used to transfer qualified packaging bags from the transfer station S3 to subsequent processes.

[0036] Specifically, the detection unit 500 includes a visual recognition component, which collects image information of the packaging bag and works in conjunction with a barcode scanner installed above the main material hopper 300 to automatically identify and verify the front and back of the packaging bag and the material number.

[0037] The material handling unit 600 includes a dual-axis drive module and a material handling end effector 630. The dual-axis drive module includes an X-axis linear module 610 and a Z-axis linear module 620. The X-axis linear module 610 is horizontally mounted above the material handling station S3, and the Z-axis linear module 620 is mounted on the slide of the X-axis linear module 610 and can reciprocate horizontally with the slide. The material handling end effector 630 is mounted on the output end of the Z-axis linear module 620 and moves vertically with the drive of the Z-axis linear module 620.

[0038] In this embodiment, the horizontal movement path of the material handling end effector 630 is equipped with subsequent process equipment and a waste bin 700. When the vision recognition component identifies a defective product, the system automatically instructs the material transfer unit 600 to sort it into the waste bin 700. This achieves automatic rejection of defective products during the production process, effectively preventing quality problems such as incorrect or reversed materials from flowing into subsequent processes, and significantly improving the quality consistency of the final product and the level of intelligent production. Qualified packaging bags are then transferred to the subsequent process equipment by the material transfer unit.

[0039] In this embodiment, each support position 421 is provided with several through holes, and a set of adsorption mechanism 440 is provided below each support position 421. The adsorption mechanism 440 includes a lifting assembly and a plurality of vacuum suction cups 442 mounted on the lifting assembly, as well as vacuum pipelines connected to each vacuum suction cup 442 respectively, and the vacuum pipelines are connected to an external vacuum generator. The lifting assembly includes a lifting plate 441 for mounting the plurality of vacuum suction cups 442 and a lifting rod 443 fixed to the bottom of the lifting plate 441. The lifting rod 443 is connected to the second rotating platform 430 through a linear bearing and moves up and down relative to the second rotating platform 430.

[0040] Below the main loading station S1, a lifting drive device 450 is provided, with its output end arranged vertically upward. When the bottom ends of each lifting rod 443 rotate with the second rotating platform 430 to the main loading station S1, they are aligned with the output ends of the lifting drive device 450 in sequence. The lifting drive device 450 is activated, pushing the lifting rods 443 and the lifting plate 441 upward. The vacuum suction cup 442 rises, passes through the through hole of the through hole support position 421, and continues to rise until it contacts the packaging bag at the bottom of the main material bin 300 and completes the adsorption. Then the lifting drive device 450 returns, and the vacuum suction cup 442 carries the packaging bag down, finally placing the packaging bag stably on the support position 421, where it is held in place by the vacuum suction cup 442.

[0041] Furthermore, in order to drive the lifting plate 441 to move smoothly up and down, multiple lifting rods 443 are vertically fixed below the lifting plate 441; each lifting rod 443 is respectively inserted into a linear bearing on the second rotating platform 430, and its bottom end corresponds to the output end of the lifting drive device 450.

[0042] In this embodiment, the first rotating platform 420 has two parallel packaging bag support positions 421 at each of the main feeding station S1, the inspection station S2, and the transfer station S3, to process two packaging bags simultaneously, thereby significantly improving the feeding efficiency per unit time. Correspondingly, the hopper platform 200 has two sets of corresponding main hoppers 300 above the main feeding station S1, for continuously feeding materials to the two support positions 421 respectively. Similarly, two sets of inspection units 500 are also provided above the inspection station S2, which can simultaneously identify and detect the status of the two packaging bags located at the inspection station S2.

[0043] To achieve synchronous material handling of the parallel support positions 421, a linkage plate is fixedly connected to the output end of the lifting drive device 450; the two ends of the linkage plate along its horizontal extension direction are respectively connected to the lifting rods 443 below the paired support positions 421.

[0044] To further enhance the continuous operation capability of the equipment, the hopper platform 200 is also equipped with two sets of parallel buffer hoppers 800. Correspondingly, the first rotating platform 420 also has two parallel packaging bag support positions 421. The two sets of buffer hoppers 800 have the same structure as the two sets of main hoppers 300 and are arranged together around the vertical rotation center axis. Below the two sets of buffer hoppers 800 on the main worktable 100, a lifting drive device 450 is also provided. Its output end is vertically upward and corresponds to the lifting rod 443 below the support position 421 through which the rotation passes, forming a loading standby station S4.

[0045] The loading standby station S4 is located on the rotation path of the first rotary platform 420. Its working logic is as follows:

[0046] When the materials in the two main material bins 300 located at the main feeding station S1 are exhausted, the servo motor 410 can drive the first rotating platform 420 and the second rotating platform 430, causing the support position 421 to rotate to the feeding standby station S4. Then, the lifting drive device 450 below it is activated, driving the corresponding lifting rod 443 and vacuum suction cup 442 to rise, so that the material picking operation can continue from the buffer bin 800.

[0047] This design, by adding a backup feeding station S4, achieves seamless material supply, avoids machine downtime due to material shortage in the main silo, and greatly improves the continuous operation efficiency and overall equipment utilization of the automated production line.

[0048] When there are still materials in the two main material bins 300, the material loading standby station S4, after the material loading station S1 completes the material retrieval, rotates with the first rotating platform 420 and stops above the material loading standby station S4. The packaged bags that have been picked up on the support station 421 form an online buffer on the material loading standby station S4. At this time, the lifting drive device 450 below does not operate.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
