Description
Technical Field
The utility model discloses an air tightness detection device of cuboid pocket of built-in cubic material belongs to the packaging machinery field.
Background
As shown in the attached drawing 3, the film bags are filled with block materials without flowability, after the rectangular material bag A is subjected to vacuum-pumping and heat-sealing, a blank section with a certain length is reserved at the bag opening part of the rectangular material bag A, the two film bags are attached together, the foremost end of the blank section is a heat-sealing line 11, the film bags at the rectangular part tightly wrap the block materials in the rectangular material bag under the action of atmospheric pressure, and therefore the material bag is kept to be rectangular. However, in actual production, the heat seal may leak, so it is necessary to detect whether the air tightness of the rectangular bag is good, and the bag with the problem of gas leakage needs to be removed off line, and cannot enter the subsequent process.
SUMMERY OF THE UTILITY MODEL
In order to detect whether the cuboid material bag filled with the blocky materials has the air leakage problem, the utility model provides an air tightness detection device of the cuboid material bag filled with the blocky materials, which comprises a conveyor 1, a side push cylinder 9 is arranged on the longitudinal beam on one side of the conveyor 1, a side push plate 10 is arranged at the cylinder rod end of the side push cylinder 9, a portal frame 2 is also connected on the longitudinal beam on the two sides of the conveyor 1, a bag suction cylinder 5 is arranged at the upper end of the portal frame 2, the axis of the bag suction cylinder 5 forms a certain included angle with the vertical direction, the cylinder rod end of the bag suction cylinder 5 is connected with a vacuum tee body 4, a vacuum suction cup 3 is arranged at the lower port of the vacuum tee body 4, the suction force of the vacuum suction cup 3 is less than one half of the weight of the cuboid material bag A, the right port of the vacuum tee body 4 is connected with a vacuum switch 8, the left port of the vacuum tee body 4 is connected with a vacuum source, a detection plate 6 is also arranged at the upper end side of the vacuum tee body 4, the side of the detection plate 6 is provided with a detection switch 7, the detection switch 7 is fixed ON the gantry 2, the detection device further comprises a control system, when the control system receives a signal sent by the detection switch 7 and an OFF signal sent by the vacuum switch 8, the air tightness of the cuboid material bag A is judged to be good, and when the control system receives the signal sent by the detection switch 7 and an ON signal sent by the vacuum switch 8, the air tightness of the cuboid material bag A is judged to be not good.
The utility model discloses a theory of operation is:
A. the cuboid material bag A subjected to vacuum heat sealing is conveyed to a detection position by a conveyor 1 and then stops, a bag suction cylinder 5 drives a vacuum sucker 3 and a detection plate 6 to move downwards, the detection plate 6 leaves the sensing position of a detection switch 7, the vacuum sucker 3 is tightly pressed at the position, close to the bag opening, of the upper surface of the cuboid material bag A, the vacuum sucker 3 sucks a film bag ON the surface of the cuboid material bag A after a vacuum source is switched ON, a vacuum switch 8 sends an ON signal, then the bag suction cylinder 5 drives the vacuum sucker 3 and the detection plate 6 to reset upwards, and the detection switch 7 sends a signal to a control system;
B. if the air tightness of the cuboid material bag A is good, the vacuum chuck 3 cannot lift the cuboid material bag A due to the fact that the suction force of the vacuum chuck 3 is smaller than the weight of the cuboid material bag A, the vacuum chuck 3 is separated from the film bag, the vacuum switch 8 sends an OFF signal at the moment, the control system judges that the air tightness of the cuboid material bag A is good, and the cuboid material bag A can be continuously conveyed to the next procedure;
C. if cuboid pocket A's heat-seal effect is not good and the gas leakage phenomenon appears, then vacuum chuck 3 will be able to hold the membrane bag to open the two-layer membrane bag that the sack part laminating is in the same place, vacuum switch 8 will send the ON signal, control system judges this cuboid pocket A's gas tightness is not good, and side push cylinder 9 drive side push pedal 10 at this moment removes and pushes away the cuboid pocket A of gas leakage and makes its line of inserting 1.
The utility model has the advantages that: utilize vacuum chuck 3 to hold cuboid pocket A's surperficial membrane bag, utilize vacuum switch 8 to detect vacuum chuck 3 and whether separate with the membrane bag, combine detect switch 7 to monitor the change value of membrane bag in the direction of height simultaneously, realized that the automatic detection of the cuboid pocket A gas tightness of built-in cubic material rolls off the production line with automatic rejection, improved the reliability of evacuation heat-seal packing unit.
