[0024] In order to solve the problem of low unpacking efficiency in the prior art, the present utility model provides an automatic bag hanging and unpacking device.

[0025] As Figures 1 to 3 shown, the automatic bag hanging and unpacking device includes a hanging frame 10, a bag hanging component 20 and an unpacking component 30. The bag hanging component 20 is movably connected to the hanging frame 10, and the bag hanging component 20 has a hanging end for hanging the hanging belt of the ton bag; the unpacking component 30 is connected to the hanging frame 10 and is arranged above the hanging end in a liftable manner. During unpacking, the unpacking component 30 descends and acts on the ton bag, and provides an auxiliary force for the ton bag to leave the hanging end.

[0026] In this embodiment, by setting the unpacking component 30 to provide an auxiliary force for the ton bag to leave the hanging end, the unpacking speed of the ton bag is accelerated, and the phenomenon of bag hanging that may occur during unpacking is avoided. Specifically, the hanging belt of the ton bag is hung on the hanging end. When unpacking is required, the unpacking component 30 can descend and press on the ton bag, thereby providing an auxiliary force for the ton bag to leave the hanging end, so as to accelerate the ton bag to leave the hanging end. When bag hanging or moving the ton bag is required, the unpacking component 30 rises to avoid the ton bag and the hanging end. In this way, not only the unpacking efficiency is improved, the problem that the ton bag is difficult to separate may be avoided, and at the same time, it does not interfere with the bag hanging component 20. Moreover, compared with the traditional device, in this embodiment, the bag hanging component 20 and the unpacking component 30 are combined and arranged, which saves the equipment space and further simplifies the equipment structure, and improves the automation degree of the automatic bag hanging and unpacking device.

[0027] As Figure 1As shown, in the present embodiment, there are multiple hanging ends, and hanging ends are provided on both sides of the hanger 10. In this way, the ton bag can be placed between the relatively arranged hanging ends, so that the ton bag has hanging ends fixed in multiple directions, thereby improving the stability and reliability of the ton bag hanging; the bag unloading component 30 includes a bag unloading fixing seat 31, a bag unloading plate 32, and a first driving member 33, and the bag unloading fixing seat 31 is connected to the hanger 10; the bag unloading plate 32 is located between the hanging ends, and the bag unloading plate 32 can be swung up and down relative to the bag unloading fixing seat 31; the first driving member 33 is drivingly connected to the bag unloading plate 32, and drives the bag unloading plate 32 to swing up and down relative to the bag unloading fixing seat 31. When unloading the bag, the first driving member 33 drives one side of the bag unloading plate 32 to swing downward, and the bag unloading plate 32 drives the hanging belt on one side of the ton bag to detach from the hanging end, thereby improving the bag unloading efficiency of the ton bag. Specifically, in the present embodiment, the hanger 10 is arranged in a square shape, and a through hole is provided on the surface of the hanger 10 for the bag stripping assembly 30 to pass through, so that the bag stripping fixed seat 31 and the first driving member 33 are located above the hanger 10, and the bag stripping plate 32 is located below the hanger 10. The bag stripping plate 32 is arranged in a cross-shaped structure, and the four protruding parts on the side of the cross-shaped structure avoid the direction of the hanging end, so that the bag stripping plate 32 can press down the ton bag when swinging up and down without interfering with the hanging end. The first driving member 33 is rotatably connected to the bag stripping plate 32, and a rotating rod is hinged on one side of the bag stripping plate 32 close to the first driving member 33. The hinge between the rotating rod and the bag stripping plate 32 is located at one of the protruding parts of the cross-shaped structure of the bag stripping plate 32, and the two ends of the rotating rod are respectively hinged to the bag stripping plate 32 and the first driving member 33 to ensure that the bag stripping plate 32 can swing up and down, and at the same time ensure the swing amplitude of the bag stripping plate 32. In this way, driven by the first driving member 33, the bag stripping plate 32 can swing up and down under the hanger 10 to provide auxiliary force for the ton bag to leave the hanging end.

[0028] like Figure 2 As shown, in this embodiment, the unpacking assembly 30 further includes a lifting rod 34 and a second driving member, the lifting rod 34 is connected to the unpacking fixed seat 31, the lifting rod 34 can be raised and lowered relative to the unpacking fixed seat 31, the unpacking plate 32 and the first driving member 33 are both connected to the lifting rod 34, and the unpacking plate 32 is rotatably connected to the bottom end of the lifting rod 34; the second driving member is drivingly connected to the lifting rod 34, and drives the lifting rod 34 to drive the unpacking plate 32 and the first driving member 33 to move up and down relative to the unpacking fixed seat 31. Specifically, the lifting rod 34 passes through the through hole of the hanger 10, the part of the lifting rod 34 above the hanger 10 is movably connected to the unpacking fixed seat 31, the second driving member can be fixed to the unpacking fixed seat 31 to drive the lifting rod 34 to rise and fall, and the part of the lifting rod 34 below the hanger 10 is connected to the rotating rod, thereby driving the unpacking plate 32 to rise and fall. In this way, the second driving member drives the lifting rod 34 and drives the bag stripping plate 32 to rise and fall, so that the bag stripping plate 32 can be switched between the bag stripping position and the avoidance position for the ton bag.

[0029] In this embodiment, the unpacking assembly 30 further includes a slider 35, a slide rail 36 and a plurality of limiting members 37. The slider 35 is located on one of the lifting rod 34 and the unpacking fixing seat 31; the slide rail 36 is located on the other of the lifting rod 34 and the unpacking fixing seat 31. The slide rail 36 extends longitudinally, and the slider 35 is movably arranged on the slide rail 36; the limiting members 37 are connected to the slide rail 36, and the limiting members 37 are arranged at both the upper and lower ends of the slide rail 36, and the slider 35 is located between the limiting members 37 at both ends. Specifically, in this embodiment, the slide rail 36 is arranged on the lifting rod 34, the slider 35 is connected to the unpacking fixing seat 31, and a limiting member 37 is arranged at each end of the slide rail 36 to ensure the connection between the slider 35 and the slide rail 36, prevent the slider 35 from disengaging from the slide rail 36, and at the same time be able to limit the lifting distance of the lifting rod 34, that is, the up and down positions of the unpacking plate 32, so that the unpacking plate 32 can move up and down within an effective range.

[0030] Such as Figure 3As shown, in this embodiment, the bag hanging assembly 20 includes a bag hanging fixed seat 21, a movable seat 22, a hanging member 23, and a third driving member 24. The bag hanging fixed seat 21 is connected to the hanging frame 10; the movable seat 22 is rotatably connected to the bag hanging fixed seat 21; the hanging member 23 extends horizontally and is connected to the movable seat 22 and rotates synchronously under the drive of the movable seat 22. The hanging member 23 has a hanging end, and the movable seat 22 has an open state that drives the hanging end to move away from the bulk bag and a hanging state that drives the hanging end to extend into the hanging belt. The third driving member 24 is drivingly connected to the movable seat 22 and drives the movable seat 22 to rotate relative to the bag hanging fixed seat 21 to drive the movable seat 22 to switch between the open state and the hanging state. In this way, when the third driving member 24 drives the movable seat 22 to approach the bulk bag, the movable seat 22 switches from the open state to the hanging state, and the hanging end extends into the hanging belt of the bulk bag. When the third driving member 24 drives the movable seat 22 to move away from the bulk bag, the movable seat 22 switches from the hanging state to the open state, and the hanging belt of the bulk bag disengages from the hanging end. Specifically, in this embodiment, a hole penetrating the upper and lower surfaces is provided on the hanging frame 10 so that the bag hanging assembly 20 can pass through. In this way, the bag hanging fixed seat 21 and the third driving member 24 are arranged above the hanging frame 10, and the movable seat 22 and the hanging member are arranged below the hanging frame 10; the movable seat 22 is arranged in an L shape, and both ends of one side of the L shape are respectively hinged to the bag hanging fixed seat 21 and the third driving member 24. The third driving member 24 is arranged longitudinally, and the end of the third driving member 24 away from the movable seat 22 is hinged to the bag hanging fixed seat 21. Thus, when the third driving member 24 acts, it can drive the movable seat 22 to rotate around the hinge point between the movable seat 22 and the bag hanging fixed seat 21; the hanging member 23 is arranged at the end of the movable seat 22 away from the fixed seat and the third driving member 24 so that the movable seat 22 can drive the hanging member 23 to move away from and close to the bulk bag synchronously. Preferably, the cross-section of the end of the pipe connector away from the movable seat 22 is larger than the cross-section of the end of the pipe connector close to the movable seat 22, thereby improving the reliability of the bulk bag hanging.

[0031] In this embodiment, there are multiple hanging bag assemblies 20, and the hanging bag assemblies 20 are arranged on both opposite sides of the hanging frame 10. When the movable seats 22 are in the open state, the movable seats 22 are located at positions away from each other, so as to facilitate the placement of the ton bags between the hanging bag assemblies 20 or facilitate the detachment of the ton bags from the hanging ends; when the movable seats 22 are in the hanging state, the movable seats 22 are located at positions close to each other, so that the ton bags can be hung on the hanging ends. Specifically, in this embodiment, the hanging bag assemblies 20 are evenly distributed in four along the circumferential direction of the hanging frame 10 and are respectively arranged at the four corners of the hanging frame 10. The bag-detaching assembly 30 is arranged between two adjacent hanging bag assemblies 20, and the bag-detaching plate 32 is located at the center position of the four hanging ends to ensure that the swinging of the bag-detaching plate 32 can assist the hanging straps on the periphery of the ton bag to detach from the hanging ends. In this way, before the hanging frame 10 approaches the ton bag, the hanging bag assemblies 20 are in the open state. When the hanging frame 10 moves above the ton bag, the ton bag is located in the middle of the four hanging bag assemblies 20, and the movable seats 22 switch from the open state to the hanging state, and the movable seats 22 approach each other, so that the hanging ends approach each other until the hanging ends are located below the hanging straps of the ton bag to complete the hanging of the ton bag. Of course, when the ton bag is to be detached from the bag, the hanging bag assemblies 20 can also cooperate with the bag-detaching assembly 30 to complete the detachment of the ton bag, that is, the movable seats 22 can also switch from the hanging state to the open state, so that the movable seats 22 are away from each other, so that the hanging ends are away from each other until the hanging straps of the ton bag can fall off from the hanging ends. At the same time, the bag-detaching assembly 30 moves downward and the bag-detaching plate 32 swings up and down to assist in detaching the bag, so as to realize the detachment of the ton bag.

[0032] In this embodiment, the hanging bag assembly 20 further includes a locking mechanism 25. At least a part of the locking mechanism 25 is movably connected to the movable seat 22. The locking mechanism 25 has a locking end, and the locking end has a locking state of approaching the hanging end and preventing the hanging strap from detaching from the hanging end and an unlocking state of being away from the hanging end. In this way, when the locking end is in the locking state, the hanging strap of the ton bag is hung on the hanging end, and the locking end locks the position of the hanging strap of the ton bag, and the ton bag can complete actions such as moving; when the locking end is in the unlocking state, the locking end is away from the hanging end, so that the side bag of the ton bag can fall off from the hanging end, and the bag-detaching action can be realized.

[0033] In this embodiment, the locking mechanism 25 includes a locking member 251 and a fourth driving member 252. The locking member 251 has a locking end. The locking member 251 is located above the hanging member 23 and is vertically movable. The fourth driving member 252 is drivingly connected to the locking member 251 and drives the locking member 251 to switch between a locked state and an unlocked state. Specifically, in this embodiment, the locking member 251 is located above the hanging member 23. The locking member 251 is formed by two bent and connected long rods to form an L shape. The fourth driving member 252 is arranged on one side of the movable seat 22 away from the hanging end and is vertically arranged. The guide rod can be telescoped up and down to drive the locking member 251 to move up and down. In this way, when the locking member 251 approaches the hanging member 23, a closed quadrilateral structure is formed among the locking member 251, the hanging member 23, and the fourth driving member 252, so as to lock the ton bag hanging belt inside the quadrilateral structure area. When the bag needs to be removed, the fourth driving member 252 drives the locking member 251 to move upward and away from the hanging member 23, so that the ton bag can be disengaged from the position between the hanging member 23 and the locking member 251. Optionally, the first driving member 33, the second driving member, the third driving member 24, and the fourth driving member 252 can be set as cylinders, electric cylinders, etc. Since the cooperation between the locking member 251 and the hanging member 23 requires precise positioning and the space here is small, the fourth driving member 252 in this embodiment adopts a cylinder with a guide rod and three rods to ensure the precise cooperation between the locking member 251 and the hanging member 23 and ensure the hanging quality of the ton bag.

[0034] In this embodiment, in order to ensure the effective cooperation between the locking member 251 and the hanging member 23, through holes are provided on the upper surface of the locking member 251. The locking end of the locking member 251 is located above the through holes. When the locking end is in the locked state, the locking end is located in the through holes. When the locking end is in the unlocked state, the locking end exits the through holes. In this way, when the locking end is in the locked state, it can be ensured that there is no gap through which the hanging belt of the hanging bag can escape between the locking end and the hanging member 23, so as to ensure the reliability of the hanging bag connection and thus ensure the stability during the movement of the hanging bag.

[0035] In this embodiment, the automatic hanging and bag removing device further includes a weighing member for weighing the hanging bag. The weighing member is connected to the hanging bag assembly 20. In this way, the weighing member can not only judge the initial mass of the ton bag, but also accurately reflect the mass change of the residual material in the ton bag during the production process. Optionally, the weighing member can be selected from components such as weighing sensors and can be arranged at the locking mechanism 25.

[0036] The specific usage process of the automatic bag hanging and unpacking device in this embodiment is as follows: The ton bag is placed at the designated position, and the hanging frame 10 moves downward to a certain distance above the ton bag; the movable seat 22 retracts inward until the hanging member 23 is located below the hanging belt of the ton bag, the locking member 251 is located above the hanging belt, and the hanging belt is located at one end of the pipe connector close to the fourth driving member 252; the guide rod of the fourth driving member 252 descends, so that the locking member 251 just inserts into the through hole of the hanging member 23; the hanging frame 10 moves upward, and the weighing member shows the initial weight of the ton bag at this time; the ton bag enters the unpacking device and starts unpacking; after unpacking is completed, the hanging frame 10 moves to the waste bag recycling place, and the weighing member shows the weight of the ton bag after unpacking at this time; the fourth driving member 252 moves upward, driving the locking member 251 upward. At this time, the locking member 251 disengages from the hanging member 23, and the second driving member moves downward to the limiting member 37, and the unpacking plate 32 presses down the ton bag; the first driving member 33 acts, and the ton bag disengages from the hanging member 23 with the assistance of the unpacking assembly 30 and enters the waste bag recycling device; the hanging frame 10 rises back to the initial position. Thus, a complete bag hanging and unpacking process is completed.
