Similar component numbers in the drawings represent similar components. Obviously, the embodiments to be described below are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0024] It should also be understood that the terms used in this utility model embodiment specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model embodiments. As used in the utility model embodiment specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0025] See also Figure 1-3 The embodiment of the utility model provides an automatic bag supply device, which includes a bag storehouse 10, a bag suction device 20, a bag taking device 30 and a rotating bag feeding device 40.

[0026] The bag storehouse 10 is used to store packaging bags 70. Usually, the bag storehouse 10 is used to store a plurality of packaging bags 70, and the plurality of packaging bags 70 are stacked in the bag storehouse 10. The bag storehouse 10 is provided with an opening, and the packaging bags 70 can be taken out from the opening.

[0027] The bag suction device 20 is used to take out the packaging bag 70 from the bag library 10 ; specifically, the bag suction device 20 can perform telescopic movement to take out the packaging bag 70 from the bag library 10 .

[0028] The bag taking device 30 is connected to the rotating bag feeding device 40; the rotating bag feeding device 40 is used to drive the bag taking device 30 to rotate. After the bag taking device 30 sucks the packaging bag 70 from the bag suction device 20, the rotating bag feeding device 40 drives the bag taking device 30 to rotate to a preset loading position.

[0029] Specifically, after the bag suction device 20 is used to take out the packaging bag 70 from the bag storage 10, the rotating bag feeding device 40 drives the bag taking device 30 to rotate to the bag suction device 20, and sucks the packaging bag 70 from the bag suction device 20 (the packaging bag 70 is removed from the bag suction device 20 by sucking one side of the packaging bag 70, rather than clamping the packaging bag 70); thereafter, the rotating bag feeding device 40 drives the bag taking device 30 to rotate to a preset loading position. During the rotation, excess packaging bags 70 can be thrown off, thereby avoiding conveying multiple packaging bags 70 at one time, causing abnormalities in subsequent processes.

[0030] In the technical solution of the utility model, after the bag suction device 20 takes out the packaging bag 70 from the bag storage 10, the bag taking device 30 sucks the packaging bag 70 from the bag suction device 20 from one side of the packaging bag 70, and then the rotating bag feeding device 40 drives the bag taking device 30 to rotate to a preset loading position. During the rotation process, excess packaging bags 70 can be thrown off, thereby avoiding conveying multiple packaging bags 70 at one time, causing abnormalities in subsequent processes.

[0031] In one embodiment, the bag suction device 20 includes a first suction unit 21 and a telescopic unit 22, wherein the telescopic unit 22 is connected to the first suction unit 21, and the telescopic unit 22 is used to drive the first suction unit 21 to perform telescopic movement. The first suction unit 21 is used to suck the packaging bag 70. The telescopic unit 22 is used to drive the first suction unit 21 to perform telescopic movement, so as to transport the first suction unit 21 to the bag storage 10 to suck the packaging bag 70 and take it out.

[0032] Further, the telescopic unit 22 includes a first motor 221 and a rod 222, wherein the first motor 221 is connected to the rod 222, and the rod 222 is connected to the first suction unit 21. The first motor 221 is used to drive the rod 222 to perform telescopic movement. The rod 222 can be specifically a screw rod, which is not specifically limited in the present invention.

[0033] Further, the first suction unit 21 includes a mounting plate 211 and a first suction cup 212, wherein the first suction cup 212 is arranged on the mounting plate 211, and the rod body 222 is connected to the mounting plate 211. The mounting plate 211 is used to mount the first suction cup 212, and the number of the first suction cups 212 is multiple, and the multiple first suction cups 212 are evenly arranged on the mounting plate 211. The multiple first suction cups 212 can improve the stability of suction and avoid falling off. The multiple first suction cups 212 are evenly arranged on the mounting plate 211, which can make the suction force more uniform and further improve the reliability.

[0034] Further, the rotary bag feeding device 40 includes a second motor, a first connecting rod 41, a second connecting rod 42 and a third connecting rod 43; the automatic bag supply device also includes a bearing plate 50. The first end of the first connecting rod 41 is connected to the second motor, the second end of the first connecting rod 41 is connected to the middle of the second connecting rod 42, the first end of the second connecting rod 42 is rotatably connected to the first end of the third connecting rod 43, and the second end of the second connecting rod 42 is connected to the bag taking device 30. The second end of the third connecting rod 43 is rotatably connected to the bearing plate 50. The bearing plate 50 plays a role in supporting the third connecting rod 43.

[0035] The second motor is used to drive the first connecting rod 41 to rotate. When the first connecting rod 41 rotates, the second connecting rod 42 is driven to rotate. When the second connecting rod 42 rotates, the bag taking device 30 and the third connecting rod 43 are driven to rotate. It can be understood that the bag taking device 30 reciprocates between the loading position and the position after the bag suction device 20 takes out the packaging bag 70, so as to take the packaging bag 70 from the bag suction device 20 and send it to the loading position. A manipulator is provided at the loading position, and the manipulator is used to take the packaging bag 70 from the bag taking device 30 and send it to the next process.

[0036] Furthermore, the bag taking device 30 includes a second suction cup 31, and the second suction cup 31 is connected to the second end of the second connecting rod 42. Through the second suction cup 31, the packaging bag 70 can be sucked from one side of the packaging bag 70, avoiding the packaging bag 70 being clamped from both sides so that the packaging bag 70 cannot be thrown off. The number of the second suction cup 31 can be one or more, and the utility model is not specifically limited.

[0037] Furthermore, the automatic bag supply device further includes a negative pressure device 60, and the negative pressure device 60 is connected to the first suction cup 212 and the second suction cup 31. The negative pressure device 60 is used to provide negative pressure for the first suction cup 212 and the second suction cup 31. The negative pressure device 60 can be, for example, a vacuum pump, which is not specifically limited in the present invention.
