Description

Technical Field

[0001] The present invention relates to the technical field of packaging bag processing, and particularly relates to a lifting and bag separating mechanism. Background Art

[0002] In daily life, packaging bags are commonly used containers for filling various materials. A common packaging bag is formed by folding a plastic film in half and then thermally bonding the folded part of the packaging bag through a heat sealing mechanism to form a bag bottom. After heat sealing, a die cutting mechanism is used to cut open the middle of the heat seal to form individual packaging bags. In order to facilitate subsequent automated filling operations, the cut packaging bags need to be arranged side by side and transported to the filling mechanism through a conveying device. The existing operation method is as follows: after each packaging bag is cut, a robotic arm is used to lift the packaging bag upward at the die cutting mechanism, and then the packaging bag is horizontally moved to the conveyor belt. The conveyor belt sucks and transports the packaging bag through a suction device or other adsorption devices. Among them, the die cutting mechanism can cut multiple packaging bags simultaneously through multiple cutting knives, but the robotic arm can only lift and place one packaging bag each time it moves up and down, and the lifting efficiency of the packaging bag still needs to be improved. Summary of the Invention

[0003] The purpose of the present invention is to avoid the deficiencies of the prior art and provide a lifting and bag separating mechanism, thereby effectively solving the deficiencies existing in the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a lifting and bag separating mechanism, including a frame, on which a plurality of moving frames are arranged and a first driving device for driving the moving frames to move left and right respectively. A bag clamping device and a bag lifting mechanism for driving the bag clamping device to move up and down and back and forth are arranged on the moving frame.

[0005] Further, a guide rail is arranged on the moving frame in cooperation with the bag clamping device. The guide rail includes a vertical rail arranged on the moving frame, a moving seat that can move up and down on the vertical rail, and a horizontal rail that can move left and right on the moving seat. The bag clamping device is arranged on the front side of the horizontal rail, and the bag lifting mechanism drives the back side of the horizontal rail to move up and down and back and forth.

[0006] Further, the bag lifting mechanism includes a guide plate arranged on the moving frame, an "L"-shaped guide groove is opened on the guide plate, a clamping shaft that can move in the guide groove is arranged on the back side of the horizontal rail, a driving wheel that can rotate on the moving frame is arranged, a swing arm is arranged on the driving wheel, a long groove sleeved on the clamping shaft is arranged on the swing arm, and a driving mechanism for driving the driving wheel to rotate is arranged on the frame.

[0007] Further, the driving mechanism includes a driving rod disposed on the frame and a second driving device for driving the driving rod to rotate. The driving rod is inserted into the driving wheels on each moving frame, and the driving wheels are driven to rotate by the driving rod. The driving wheels are movably disposed on the driving rod in the left-right direction.

[0008] Further, the cross-section of the driving rod is square, and wear-resistant blocks surrounding the square are disposed on the driving wheels to cooperate with the driving rod.

[0009] Further, rollers that can roll in the guiding grooves are disposed on the clamping shafts.

[0010] Further, guide rails are disposed on the frame to cooperate with the moving frames.

[0011] Further, the first driving device includes a plurality of groups of belts and a servo motor for driving the belts to rotate. The moving frames are fixedly connected to the belts.

[0020] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more; the orientation or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention.

[0022] As Figures 1-6 shown, a lifting and bag separating mechanism described in this embodiment includes a frame 1, on which a plurality of moving frames 2 are provided and a first driving device 3 for driving the moving frames 2 to move left and right respectively. A bag clamping device 4 and a bag lifting mechanism for driving the bag clamping device 4 to move up and down and back and forth are provided on the moving frame 2; a conveyor belt 10 is provided at the frame 1 to convey the packaging bags to the next filling process.

[0023] The bag clamping device 4 is a pneumatic gripper. After the pneumatic gripper clamps the packaging bag, the bag lifting mechanism drives the bag clamping device 4 to move upward. At the same time, the first driving device 3 drives the moving frame 2 to move left and right, and the distance between the moving frames 2 increases, so that a plurality of bag clamping devices 4 separate the packaging bags from each other. Then the bag lifting mechanism drives the bag clamping device 4 to move backward to the conveyor belt 10 at the frame 1. The conveyor belt 10 sucks the packaging bags through a suction device or other adsorption devices for conveying. A plurality of bag clamping devices 4 can respectively arrange and adsorb a plurality of packaging bags on the conveyor belt 10, so that each cycle of the up and down movement of the bag clamping device 4 can lift a plurality of packaging bags, separate the adjacent packaging bags after die-cutting and adsorb them independently on the conveyor belt 10 for conveying, improving the efficiency of lifting the packaging bags and saving a large amount of electric energy; in this embodiment, there are two moving frames 2 provided on the frame 1. The die-cutting mechanism can die-cut two packaging bags. After two bag clamping devices 4 clamp the two packaging bags, the two packaging bags can be lifted and separated at the same time and adsorbed on the conveyor belt 10 for conveying.

[0024] Preferably, a guide rail 5 is provided on the moving frame 2 in cooperation with the bag clamping device 4. The guide rail 5 includes a vertical rail 51 provided on the moving frame 2. A moving seat 52 is movably provided on the vertical rail 51 in the up-and-down direction. A horizontal rail 53 is movably provided on the moving seat 52 in the left-and-right direction. The bag clamping device 4 is provided on the front side of the horizontal rail 53. The bag lifting mechanism drives the rear side of the horizontal rail 53 to move up and down and move forward and backward; the bag clamping device 4 moves up and down and forward and backward on the moving frame 2 through the cooperation of the horizontal rail 53 and the vertical rail 51 (the movement of the bag clamping device 4 is a translation, which can keep the vertical state of the bag clamping device 4, so that the packaging bag can be vertically lifted and adsorbed on the conveyor belt 10); when the bag lifting mechanism drives the horizontal rail 53 to move up and down, the bag clamping device 4 and the horizontal rail 53 move up and down on the vertical rail 51 through the moving seat 52. When the bag lifting mechanism drives the horizontal rail 53 to move horizontally, the bag clamping device 4 and the horizontal rail 53 move forward and backward on the moving seat 52;

[0025] Preferably, the bag lifting mechanism includes a guide plate 61 provided on the moving frame 2. An "L"-shaped guide groove 62 is formed on the guide plate 61. A clamping shaft 54 that can move in the guide groove 62 is provided on the rear side of the horizontal rail 53. A driving wheel 63 is rotatably provided on the moving frame 2. A swing arm 64 is provided on the driving wheel 63. A long groove 65 sleeved on the clamping shaft 54 is provided on the swing arm 64. A driving mechanism 7 for driving the driving wheel 63 to rotate is provided on the machine frame 1; the driving mechanism 7 drives the driving wheel 63 to rotate, so that the swing arm 64 swings within a certain angle. The swing arm 64 cooperates with the clamping shaft 54 through the long groove 65. When the swing arm 64 swings, it can drive the rear end of the horizontal rail 53 to move in the guide groove 62 through the clamping shaft 54. Since the bag clamping device 4 can only move up and down and forward and backward through the horizontal rail 53 and the vertical rail 51, the horizontal rail 53 will not rotate, so that the bag clamping device 4 can translate along an "L"-shaped track parallel to the guide groove 62, that is, move up and down and forward and backward, so that the bag clamping device 4 lifts the packaging bag and clamps it backward to the conveyor belt 10 for conveying; preferably, a roller 66 that can roll in the guide groove 62 is provided on the clamping shaft 54, so that the clamping shaft 54 can roll and cooperate with the guide groove 62 through the roller 66;

[0026] Preferably, the driving mechanism 7 includes a driving rod 71 provided on the machine frame 1 and a second driving device 72 for driving the driving rod 71 to rotate. The driving rod 71 is inserted into the driving wheel 63 on each moving frame 2. The driving wheel 63 is driven to rotate through the driving rod 71. The driving wheel 63 is movably provided on the driving rod 71 in the left-and-right direction; the second driving device 72 is a servo motor. The servo motor drives the driving rod 71 to rotate, and the driving rod 71 drives the driving wheel 63 to swing; in this embodiment, the servo motor can drive the driving rod 71 to rotate through a chain and sprocket;

[0027] Preferably, the cross-section of the driving rod 71 is square. Wear-resistant blocks 73 that enclose a square are arranged on the driving wheel 63 to cooperate with the driving rod 71. The driving rod 71 drives the driving wheel 63 to swing through the wear-resistant blocks 73. The driving wheel 63 cooperates with the driving rod 71 through the wear-resistant blocks 73, enabling the driving wheel 63 to not only rotate with the driving rod 71 but also move left and right on the driving rod 71.

[0028] Preferably, guide rails 11 are arranged on the frame 1 to cooperate with the moving frame 2. When the moving frame 2 moves left and right on the frame 1, it can move along the guide rails 11.

[0029] Preferably, the first driving device 3 includes several groups of belts 31 and servo motors 32 that drive the belts 31 to rotate. The moving frame 2 is fixedly connected to the belt 31. Each moving frame 2 is driven by a separate group of servo motors plus belts 31. Each group of servo motors drives the belt 31 to rotate, driving the corresponding moving frame 2 to move left and right. The distances that the moving frames 2 move left and right are different, so that the packaging bags can be separated after being clamped by the bag clamping device 4.

[0030] The working process of this embodiment is as follows: After the die-cutting mechanism die-cuts two packaging bags, the two bag clamping devices 4 respectively clamp the two packaging bags. Then, the second driving device 72 drives the driving rod 71 to rotate, driving the driving wheels 63 on the two moving frames 2 to rotate synchronously. The swing arms 64 on the driving wheels 63 cooperate with the rollers 66 on the clamping shafts 54 through the long slots 65. The swing arms 64 drive the rollers 66 to move upward along the guiding slots 62, that is, the rear end of the cross rail 53 moves upward along the guiding slots 62. At this time, the bag clamping devices 4, the cross rail 53, and the moving seat 52 move upward on the vertical rail 51. At the same time, the two first driving devices 3 drive the belts 31 to rotate, causing the two moving frames 2 to move away from each other, so that the bag clamping devices 4 clamp and separate the packaging bags (in this embodiment, one of the moving frames 2 can remain stationary, and the other moving frame 2 moves, so that the two moving frames 2 can move away from each other). When the rollers 66 move upward to the end along the guiding slots 62, the driving wheels 63 continue to rotate, causing the rollers 66 to continue to move backward along the guiding slots 62, driving the cross rail 53 to move backward. At this time, the bag clamping devices 4 and the cross rail 53 move backward on the moving seat 52, causing the two packaging bags to move backward while separating until they reach the conveyor belt 10 and are adsorbed by the conveyor belt 10. The bag clamping devices 4 release the clamping of the packaging bags, and the packaging bags can be conveyed by the conveyor belt 10. Then, the first driving device 3 drives the belt 31 to rotate in the reverse direction, causing the two moving frames 2 to move closer to each other. The second driving device 72 drives the driving rod 71 to rotate in the reverse direction, driving the driving wheels 63 to rotate in the reverse direction. The swing arms 64 drive the cross rail 53 to move downward along the guiding slots 62, causing the bag clamping devices 4 to reset downward.
