Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated feeding equipment technology, specifically to an automated feeding and unloading device for packaging bags. Background Technology
[0002] Automatic bag feeders are common devices that automatically feed ordinary plastic bags. Widely used in the food and daily necessities industries, they automatically complete the bag feeding process. This equipment employs advanced mechanical structures and control systems, using conveyor belts, suction cups, and other devices to transport the plastic bags to designated positions, achieving highly efficient automatic feeding. Its advantages include high automation, simple operation, high speed, and good stability, significantly improving production efficiency and reducing labor costs, making it an indispensable piece of equipment in the modern packaging industry.
[0003] Authorization announcement number CN222591933U discloses an automatic bag feeding device and a bag-feeding packaging machine. According to its instruction manual and drawings, the solution is as follows: after the bag suction device takes the packaging bag out of the bag magazine, the bag picking device picks up the packaging bag from one side of the packaging bag from the bag suction device. Then, the rotating bag feeding device drives the bag picking device to rotate to the preset feeding position. During the rotation, excess packaging bags can be thrown off, thereby avoiding the conveying of multiple packaging bags at one time.
[0004] This method cannot simultaneously unload bags that have already been filled with materials while feeding them, resulting in a low level of automation. Furthermore, the solution has a small capacity for accommodating packaging bags, which causes inconvenience during production. Summary of the Invention
[0005] This invention addresses the problems encountered during the loading of packaging bags by providing an automatic loading and unloading device for packaging bags. During the loading process, the bag adsorption mechanism keeps the first pneumatic suction cup in an unadsorbed state and uses the piston rod of the second lifting cylinder to extend in advance until the unloading push plate is almost close to the surface of the bag placement rack. This allows the unloading push plate to simultaneously push the packaged bag onto the sliding guide plate and slide it to the outside during the loading process. The entire mechanism achieves simultaneous loading and unloading operations.
[0006] The purpose of this invention is achieved through the following technical solution: an automatic loading and unloading device for packaging bags, including a first worktable, a bag placement mechanism and a first conveying mechanism on the surface of the first worktable, a bag adsorption mechanism and a bag unloading mechanism on one side of the first conveying mechanism, and a storage mechanism for storing bags and a bag adjustment mechanism for controlling the up and down movement of the remaining bags below the bag adsorption mechanism.
[0007] Preferably, the bag placement mechanism includes a bag placement frame, a first pneumatic suction cup, and a sliding guide plate. A second worktable is also raised on the surface of the first worktable. The bag placement frame is disposed on the surface of the second worktable. A plurality of first pneumatic suction cups are installed on the surface of the second worktable. The ends of the first pneumatic suction cups pass through the surface of the bag placement frame. A sliding guide plate is also provided on the side of the second worktable near the outside.
[0008] Preferably, the first conveying mechanism includes a conveying support frame, a sliding support plate, a first slide rail, a screw support block, a first lead screw, and a sliding upright plate. The top of the conveying support frame is provided with a sliding support plate, one side of the sliding support plate is provided with a plurality of first slide rails, and the other side of the sliding support plate is provided with a plurality of screw support blocks. Each screw support block is provided with a first lead screw inside. The surface of each first slide rail is provided with a first slider that can be slidably connected. The surface of the first slider is mounted with a sliding upright plate, and the sliding upright plate is throttlely connected to the surface of the first lead screw.
[0009] Preferably, the sliding plate extends towards the first lead screw and is provided with a lead screw end cap, which is connected to the surface of the first lead screw, which is driven by a first motor. This arrangement is for the purpose of transmitting power to the first lead screw.
[0010] Preferably, the bag adsorption mechanism includes an adsorption support plate, a first lifting cylinder, a suction cup support plate, and second pneumatic suction cups. The first lifting cylinder is connected to one side of the adsorption support plate, and the piston rod end of the first lifting cylinder is connected to the suction cup support plate. The surface of the suction cup support plate is provided with several second pneumatic suction cups. This arrangement is to achieve normal adsorption of the bag.
[0011] Preferably, the bag feeding mechanism includes a feeding support plate, a second lifting cylinder, and a feeding push plate. The feeding support plate is connected to the other side of the adsorption support plate, and the second lifting cylinder is connected to the side of the feeding support plate. The piston rod end of the second lifting cylinder is connected to the feeding push plate.
[0012] Preferably, the storage mechanism includes a storage support frame and bag limiting rods. The storage support frame is disposed on the surface of the first workbench, and the surface of the storage support frame is provided with a plurality of bag limiting rods, so that the outer bags can be stacked and placed in the gap between adjacent bag limiting rods.
[0013] Preferably, the bag adjustment mechanism includes an adjustment support plate, an electric slide rail, an adjustment push plate, and an adjustment upright plate. The top of the adjustment support plate is connected to the bottom of the storage support frame. The surface of the storage support frame is also provided with a push plate clearance groove. The side of the adjustment support plate is connected to the electric slide rail. The slider surface of the electric slide rail is connected to the adjustment upright plate. The end of the adjustment upright plate passes through the push plate clearance groove and is connected to the adjustment push plate. The cross-sectional area of the adjustment push plate is smaller than the cross-sectional area formed by several bag limiting rods. The outer bags are stacked and placed on the surface of the adjustment push plate.
[0014] Compared with the prior art, this utility model has the following beneficial effects: 1. During the material feeding process, the first pneumatic suction cup of the bag adsorption mechanism is in an unadsorbed state. The piston rod of the second lifting cylinder extends in advance until the unloading push plate is close to the surface of the bag placement rack. This allows the unloading push plate to simultaneously push the packaged bags onto the sliding guide plate and slide them to the outside during the material feeding process. The entire mechanism achieves simultaneous material feeding and unloading, improving the automation level of production. 2. As the bag adsorption mechanism continuously adsorbs bags on the surface of the adjusting push plate, when the total thickness of all bags decreases, the slider of the electric slide rail drives the adjusting plate to move upward. The adjusting plate then simultaneously drives the adjusting push plate to continuously push these stacked bags higher, enabling the bag adsorption mechanism to smoothly and continuously adsorb the remaining bags, improving the automation level of production.

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:
[0021] like Figures 1 to 4 As shown, an automatic loading and unloading device for packaging bags includes a first worktable 1, the surface of which is provided with a first conveying mechanism 3. The first conveying mechanism 3 includes a conveying support frame 31, a sliding support plate 32, first slide rails 33, screw support blocks 34, a first lead screw 35, and a sliding upright plate 37. The top of the conveying support frame 31 is provided with the sliding support plate 32. One side of the sliding support plate 32 is provided with several first slide rails 33, and the other side of the sliding support plate 32 is provided with several screw support blocks 34. Each screw support block 34 has a first lead screw 35 inside. Each first slide rail 33 has a first slider 36 slidably connected to its surface. The surface of the first slider 36 is mounted with a sliding upright plate 37, which is throttle-connected to the surface of the first lead screw 35. The sliding upright plate 37 extends towards the first lead screw 35 and is provided with a lead screw end cap 38, which is connected to the surface of the first lead screw 35. The first lead screw 35 is driven by a first motor 39.
[0022] During the rotation of the shaft of the first motor 39, the first lead screw 35 can be driven to rotate. During the rotation of the first lead screw 35, the lead screw end cap 38 on its surface slides, which in turn drives the sliding upright plate 37 to slide simultaneously. During the sliding process, the first slider 36 of the sliding upright plate 37 slides relative to the first slide rail 33. During the rotation of the first lead screw 35, its left and right ends rotate relative to the interior of the screw support block 34.
[0023] In this embodiment, the surface of the first workbench 1 is also provided with a bag placement mechanism 2. The bag placement mechanism 2 includes a bag placement rack 21, a first pneumatic suction cup 22, and a sliding guide plate 23. A second workbench 11 is also provided on the surface of the first workbench 1. The bag placement rack 21 is disposed on the surface of the second workbench 11. A plurality of first pneumatic suction cups 22 are installed on the surface of the second workbench 11. The ends of the first pneumatic suction cups 22 pass through the surface of the bag placement rack 21. A sliding guide plate 23 is also provided on the side of the second workbench 11 near the outside.
[0024] After the bags are placed on the surface of the bag holder 21, the first pneumatic suction cup 22 can adhere to the bags on the surface. Each time material is placed inside the bag, the first pneumatic suction cup 22 stops adhering to the bag. At this time, the baffle pushes the bags on the surface of the bag holder 21, and these bags slide down the sliding guide plate 23 to the outside.
[0025] In this embodiment, a bag adsorption mechanism 4 and a bag unloading mechanism 5 are provided on one side of the first conveying mechanism 3. Specifically, the bag adsorption mechanism 4 includes an adsorption support plate 41, a first lifting cylinder 42, a suction cup support plate 43, and second pneumatic suction cups 44. The first lifting cylinder 42 is connected to one side of the adsorption support plate 41, and the piston rod end of the first lifting cylinder 42 is connected to the suction cup support plate 43. A plurality of second pneumatic suction cups 44 are provided on the surface of the suction cup support plate 43. The adsorption support plate 41 is fixedly connected to the sliding support plate 32.
[0026] The bag feeding mechanism 5 includes a feeding support plate 51, a second lifting cylinder 52, and a feeding push plate 53. The feeding support plate 51 is connected to the other side of the adsorption support plate 41. The side of the feeding support plate 51 is connected to the second lifting cylinder 52, and the piston rod end of the second lifting cylinder 52 is connected to the feeding push plate 53.
[0027] When the sliding support plate 32 moves the adsorption support plate 41 to the designated position, the piston rod of the first lifting cylinder 42 slides down, causing the suction cup support plate 43 to be positioned above the bag to be conveyed. Then, the second pneumatic suction cup 44 adsorbs the bag. Similarly, the sliding support plate 32 slides towards the surface of the bag placement rack 21 to readjust the position of the bag adsorption mechanism 4.
[0028] like Figure 4 As shown, during the process of the entire bag adsorption mechanism 4 moving to the right, the first pneumatic suction cup 22 is in an unadsorbed state, and the piston rod of the second lifting cylinder 52 can be extended in advance until the material push plate 53 is close to the surface of the bag placement rack 21. During the process of moving to the right, the material push plate 53 will push the packaged bag onto the sliding guide plate 23.
[0029] In this embodiment, a storage mechanism 6 for storing bags and a bag adjustment mechanism 7 for controlling the up-and-down movement of the remaining bags are provided below the bag adsorption mechanism 4.
[0030] The storage mechanism 6 includes a storage support frame 61 and bag limiting rods 62. The storage support frame 61 is disposed on the surface of the first workbench 1. The surface of the storage support frame 61 is provided with a plurality of bag limiting rods 62, and the outer bags can be stacked and placed in the gap between adjacent bag limiting rods 62.
[0031] The bag adjustment mechanism 7 includes an adjustment support plate 71, an electric slide rail 72, an adjustment push plate 74, and an adjustment upright plate 73. The top of the adjustment support plate 71 is connected to the bottom of the storage support frame 61. The surface of the storage support frame 61 is also provided with a push plate clearance groove. The side of the adjustment support plate 71 is connected to the electric slide rail 72. The slider surface of the electric slide rail 72 is connected to the adjustment upright plate 73. The end of the adjustment upright plate 73 passes through the push plate clearance groove and is connected to the adjustment push plate 74. The cross-sectional area of the adjustment push plate 74 is smaller than the cross-sectional area formed by several bag limiting rods 62. The outer bags are stacked and placed on the surface of the adjustment push plate 74.
[0032] A large number of bags are stacked within the gaps between adjacent bag-limiting rods 62, at which point the bags are also positioned on the surface of the adjusting push plate 74. As the bag adsorption mechanism 4 continuously adsorbs bags from the surface of the adjusting push plate 74, when the total thickness of all the bags decreases, the slider of the electric slide rail 72 drives the adjusting vertical plate 73 upwards. The adjusting vertical plate 73 then simultaneously drives the adjusting push plate 74 to continuously push the stacked bags higher, allowing the bag adsorption mechanism 4 to continuously adsorb the remaining bags.
[0033] Working principle and usage of this utility model:
[0034] First, the rotation of the shaft of the first motor 39 drives the first lead screw 35 to rotate. During the rotation of the first lead screw 35, the lead screw end cap 38 on its surface slides, which in turn drives the sliding upright plate 37 to slide simultaneously. When the sliding support plate 32 moves the adsorption support plate 41 to the designated position, the piston rod of the first lifting cylinder 42 slides down, causing the suction cup support plate 43 to be above the adjusting push plate 74. Then, the second pneumatic suction cup 44 adsorbs the bag. Similarly, the sliding support plate 32 slides towards the surface of the bag placement rack 21 to readjust the position of the bag adsorption mechanism 4. During the movement of the entire bag adsorption mechanism 4, the first pneumatic suction cup 22 is in an unadsorbed state, and the piston rod of the second lifting cylinder 52 can extend in advance until the feeding push plate 53 is close to the surface of the bag placement rack 21. During the movement to the right, the feeding push plate 53 pushes the packaged bags onto the sliding guide plate 23, and these bags slide down the sliding guide plate 23 to the outside.
[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
