Description

Technical Field

[0001] The utility model relates to a bagging device with a bag-connecting detection function, belonging to the field of packaging machinery. Background Art

[0002] In high-speed double-swing arm automatic packaging technology, pre-prepared pre-made bags are mostly used. After the early production and transportation, the pre-made bags are prone to static electricity and negative pressure between the bags. When taking the bags, two bags may be sucked at the same time. Patent document CN209582083U discloses a bag opening mechanism with a continuous bag detection function. Before opening the bag, the mechanism uses a bag pressing rod to press the empty bag on the pallet, and cooperates with a high-resolution detection switch to measure the thickness of the empty bag below to determine whether there is a continuous bag situation. However, if there are wrinkles in the empty bag below the detection position, it will be misjudged as a continuous bag when measuring the thickness of the empty bag, thereby reducing the accuracy of the detection, causing waste of empty bags and affecting packaging efficiency. Utility Model Content

Two groups of vertically arranged detection mechanisms 25 are symmetrically provided on the left and right sides. The swing cylinder 22 drives the swing arm 23 to realize the up and down swing of the detection mechanism 25. The detection mechanism 25 includes a connecting arm 251. The middle part of the connecting arm 251 is hinged to the upper outer side of the detection swing arm 252. The upper inner side of the detection swing arm 252 is hinged to the cylinder rod of the detection cylinder 253. The cylinder body of the detection cylinder 253 is hinged to the upper part of the connecting arm 251. The cylinder body of the detection cylinder 253 is provided with a detection magnetic ring 254. The lower part of the detection swing arm 252 is provided with an L-shaped support rod 255. The head of the support rod 255 faces one side of the swing shaft 24.

[0004] A knife inserting plate 256 is provided at the lower portion of the connecting arm 251 , and the direction of the head of the knife inserting plate 256 is consistent with the direction of the head of the supporting rod 255 .

[0005] Two groups of bag clamping swing arms 11 are symmetrically arranged on the left and right sides of the through axis of the swing arm bagging mechanism 1. The lower part of the bag clamping swing arm 11 is hinged with a clamping claw 13. The clamping claw 13 is driven to open and close by a clamping cylinder 12. The clamping cylinder 12 is hinged at the middle part of the bag clamping swing arm 11.

[0006] A bag supply mechanism 3 is provided below the swing arm bagging mechanism 1, a liftable bag opening suction cup 4 is provided at the front end of the bag supply mechanism 3, a bag blowing mechanism 5 is provided at the upper front part of the bag opening suction cup 4, both the bag opening suction cup 4 and the bag blowing mechanism 5 are connected to an external frame, and the blowing hole of the bag blowing mechanism 5 is arranged downward.

[0007] The working principle of the utility model is:

[0008] A. The bag supply mechanism 3 transports the bag opening of the empty bag A to the front bag opening suction cup 4, and the bag opening suction cup 4 opens the bag opening. The swing cylinder 22 drives the swing arm 23 to make the detection mechanism 25 swing downward and insert into the bag opening. The clamping cylinder 12 drives the clamping claws 13 to close and clamp the two sides of the empty bag A.

[0009] B. The detection cylinder 253 drives the detection swing arm 252 to make the support rod 255 swing outward. If the swing angle of the support rod 255 outward is not limited by the two sides of the empty bag A, and the support rod 255 swings to the maximum angle, the detection magnetic ring 254 sends a signal at this time, and the opened empty bag A is a continuous bag; after determining that it is a continuous bag, the clamping cylinder 12 drives the clamping claw 13 to open, and the bag opening suction cup 4 releases the empty bag A, and the bag supply mechanism 3 continues to move the empty bag A forward, and the bag blowing mechanism 5 blows the double bags to the bottom after ventilation; if the swing angle of the support rod 255 outward is limited by the two sides of the empty bag A and cannot swing to the maximum angle, the detection magnetic ring 254 does not send a signal at this time, and the opened empty bag A is a single bag, and the next step of bagging is carried out;

[0010] C. After determining that it is a single bag, the bag opening suction cup 4 releases the empty bag A, and the external driving mechanism causes the bag insertion detection mechanism 2 and the bag clamping swing arm 11 to swing upward to the bagging position, and the swing cylinder 22 drives the swing arm 23 to swing the detection mechanism 25 upward to perform the bagging action.

[0011] The beneficial effects of the utility model are:

[0012] A. The bag insertion detection mechanism 2 arranged on the swing arm bagging mechanism 1 can be used to perform continuous bag detection after the bag is opened, further improving the detection accuracy, solving the problem of inaccurate detection due to wrinkles in empty bags, avoiding the problem of material spillage caused by subsequent material filling after bagging, improving the reliability of the packaging equipment, and meeting the packaging needs of packaging speeds above 1200 bag / h.

[0013] B. The detection magnetic ring 254 provided on the detection cylinder 253 and the driving support rod 255 are swung outward, which occupies a small space and has a compact layout, thus meeting the needs of continuous bag detection of the double swing arm bag grabbing structure under high-speed packaging.

[0014] C. The empty bags A detected as connected bags are blown out of the device in time by the bag blowing mechanism 5, so as to provide guarantee for continuous production and packaging operation. BRIEF DESCRIPTION OF THE DRAWINGS
