Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to an automatic moving, separating, grabbing and placing device for packaging bags. Background Art

[0002] In the production line process of disposable oral instrument boxes, it is necessary to separate and clamp the packaging bags and put them outside the instrument boxes for packaging. The separation process of the existing packaging bag separation equipment is as follows: the packaging bags are placed in the positioning box, and the suction cup located under the positioning box rises to suck a packaging bag and pulls it down. The packaging bag is grabbed by the robot, the suction cup is released, and the packaging bag is pulled out from under the positioning box by the gripper and placed on the production line.

[0003] In order to leave space for the robot to grasp, the distance between the suction cup and the positioning box is large. The suction cup pulls down the packaging bag. When the packaging bag is grasped and pulled out by the robot, the upper packaging bag is sometimes pulled out a little, and the head of the packaging bag is bent. The suction cup cannot hold on to this packaging bag next time. Summary of the invention

[0004] The utility model aims to overcome the defects in the prior art and provide an automatic moving, separating and placing device for packaging bags which can prevent the packaging bags from bending during the extraction process and can distribute the packaging bags quickly and reliably.

[0005] The utility model is implemented as follows: an automatic moving, separating, grasping and placing device for packaging bags comprises a frame, a bag film bin, a bottom plate, a bag film supporting plate, a first rodless cylinder, an adsorption device, a bag clamping assembly and a second rodless cylinder, wherein the bag film bin is fixed on the bottom plate, the bottom plate is located above the bag film supporting plate, the bag film supporting plate is fixed on the frame, the adsorption device is located in front of and below the bag film supporting plate, the bottom plate is connected to a slider of the first rodless cylinder, and the first rodless cylinder drives the bag film bin to move forward and backward through the bottom plate; a bag film outlet is provided at the bottom front end of the bag film bin, when the bag film bin moves forward, the bag film outlet is located in front of the bag film supporting plate, the adsorption device is located below the bag film outlet, and when the bag film bin moves backward, the bag film outlet is located above the bag film supporting plate and is closed by the bag film supporting plate; the bag clamping assembly is located in front of the bag film outlet, and the bag clamping assembly is connected to the second rodless cylinder.

[0006] The top of the bag film bin is open, and at least two sides of the four sides of the bag film bin are provided with bag film placement openings.

[0007] The bag clamping assembly comprises a gripper and a slide cylinder. The slide cylinder is connected to the second rodless cylinder via a connecting assembly, and the gripper is fixed on the slide cylinder.

[0008] The first rodless cylinder and the second rodless cylinder are rodless cylinders with buffers respectively.

[0009] The adsorption device comprises 2-6 suction cups and a lifting cylinder. The suction cup is located below the bag film outlet, and the lower end of the suction cup is fixed on the output end of the lifting cylinder.

[0010] The length of the bag film outlet is 10-20 cm and the width is 3-6 cm.

[0011] The distance between the bottom plate and the bag film supporting plate is 0.1-3 cm.

[0012] The beneficial effect of the utility model is that the bag film bin moves forward, the adsorption device rises to suck and pull down a packaging bag, and the bag film bin retreats. Because the distance between the suction cup of the adsorption device and the bag film bin is small, the adsorbed packaging bag is separated from the bag film bin, and the upper packaging bag will not be pulled out and bent. The packaging bag is laid flat on the bag film supporting plate, and the separated packaging bag is placed on the conveying positioning plate through the gripper, and the distribution is fast and reliable.

[0017] according to Figure 1-Figure 3 The utility model is an automatic moving separation and grasping device for packaging bags, comprising a frame 1, a bag film bin 2, a bottom plate 3, a bag film supporting plate 4, a first rodless cylinder 5, an adsorption device 6, a bag clamping assembly 7 and a second rodless cylinder 8. The top of the bag film bin 2 is open, and at least two sides of the bag film bin 2 are provided with bag film placement openings 10, and the bag film bin 2 is fixed on the bottom plate 3.

[0018] The bottom plate 3 is located above the bag film support plate 4, and the bag film support plate 4 is fixed on the frame 1. The adsorption device 6 is located in the front and lower part of the bag film support plate 4. The bottom plate 3 is connected to the slider of the first rodless cylinder 5, and the first rodless cylinder 5 drives the bag film bin 2 to move forward and backward through the bottom plate 3; a bag film outlet 9 is provided at the bottom of the front end of the bag film bin 2. When the bag film bin 2 moves forward, the bag film outlet 9 is located in front of the bag film support plate 4, and the adsorption device 6 is located below the bag film outlet 9. When the bag film bin 2 moves backward, the bag film outlet 9 is located above the bag film support plate 4 and is blocked by the bag film support plate 4; the bag clamping assembly 7 is located in front of the bag film outlet 9, and the bag clamping assembly 7 is connected to the second rodless cylinder 8.

[0019] The bag clamping assembly 7 includes a gripper 11 and a slide cylinder 12. The slide cylinder 12 is connected to the second rodless cylinder 8 via a connecting assembly 13. The gripper 11 is fixed to the slide cylinder 12. The connecting assembly 13 is preferably a connecting plate and a connecting bolt. The first rodless cylinder 5 and the second rodless cylinder 8 are rodless cylinders with buffers.
