As shown in fig. 4, the plastic tube 1 dropped from the tube guiding bracket 13 falls on the upper inclined guiding rod 101 of the tube collecting and blanking mechanism under the action of its own gravity, and continues to roll along the upper inclined guiding rod 101 to the lower inclined guiding rod 102 under the action of gravity; at this time, the front telescopic mechanism 103 of the lower inclined guide bar 102 is extended and the rear telescopic mechanism 103 is retracted, so that the plastic tube 1 is accumulated and collected along the slope of the lower inclined guide bar 102. The tube guiding and feeding device continues to feed plastic tubes 1 to the collecting unit 15, when the number of bundles is reached, the number of bundles can be 1, 2 or more. When the bundling number is reached, the telescopic mechanisms 103 at the upper part and the rear part of the lower inclined guide rod 102 extend out, the telescopic mechanisms 103 at the front part retract, and the plastic pipes 1 collected between the two telescopic mechanisms 103 roll down along the inclined plane of the lower inclined guide rod 102 one by one to realize quantitative blanking; the plastic pipe 1 rolled down from the lower inclined guide bar 102 falls into the pipe receiving straight groove 21 by gravity.

Subsequently, the plastic tube 1 rolled down from the lower inclined guide bar 102 is positioned between the movable front fence 23 and the rear push plate 22; at this time, the second linear driving mechanism drives the front baffle 23 to move downwards to shield the circular through hole 371, the motor of the first linear driving mechanism rotates in the forward direction, the driving wheel rotates to drive the transmission belt 243 to operate, the rear push plate 22 moves towards the front baffle 23 along with the fifth slider 244 connected with the transmission belt 243, so that the plurality of plastic tubes 1 are pushed to move towards the movable front baffle 23, when the front ends of the plastic tubes 1 are in contact with the movable front baffle 23, and when the rear ends of the plastic tubes 1 are in contact with the rear push plate 22, the end parts of the plurality of plastic tubes are aligned;

then, the second linear driving mechanism drives the front baffle 23 to move upwards until the circular through hole 371 is opened, and then the motor of the first linear driving mechanism continues to rotate in the forward direction, so as to drive the rear push plate 22 to push the plastic pipe 1 to continue to move forwards, so that the plastic pipe 1 is pushed out from the circular through hole 371; the rear push plate 22 pushes the plastic pipe 1 to move forwards, so that the front end of the plastic pipe 1 is conveyed to the pipe holding tool 49 through the pipe channel 408, the air cylinder drives the arc-shaped hoop arms 491 to repeatedly loosen and hold tightly, a plurality of plastic pipes 1 can be smoothed out, and finally the plastic pipes 1 are held tightly by the two arc-shaped hoop arms 491;

then, the vertical cylinder 32 of the labeling manipulator 3 moves, the piston rod of the vertical cylinder extends downwards, an air source of the vacuum suction cup 33 is opened at the same time, the vacuum suction cup 33 is contacted with the qualified label 36 at the top, the vacuum pressure sensor detects that the workpiece is adsorbed, a signal is transmitted to the labeling manipulator, after the piston rod of the vertical cylinder 32 retracts for a certain distance, the driving device 31 starts to operate to drive the vertical cylinder 32 to rotate for a certain angle in the horizontal plane, the piston rod of the vertical cylinder 32 extends downwards to place the adsorbed qualified label 36 on a spool passing from the bottom, and labeling is completed; subsequently, the labelling manipulator is reset.

Then, as shown in fig. 9, 14 and 15, the motor of the first tape winding manipulator starts to operate to drive the first tape loading device 41 to rotate around the plastic pipe 1, because one end of the adhesive tape 46 is hung on the fixed seat, two ends of the output section of the adhesive tape 46 are stressed and tensioned, and when the first tape loading device 41 rotates around the plastic pipe 1, the adhesive tape 46 is tightly attached to the surface of the plastic pipe to realize the binding of a plurality of plastic pipes 1; as the first loading means 41 continues to rotate around the plastic pipe 1, the adhesive tape 46 will exert a wrapping force on a length of the adhesive tape 46 hanging on the mounting base, the wrapping force being greater than the adhesive force of the adhesive tape 46 and the clamping force of the clamping plate 45, thereby releasing the adhesive tape 46 from the mounting base.

After the tape 46 is wound a set number of times, as shown in fig. 12, the axial arm 48 of the first entrainment device is extended and the tape 46 will be wound around the axial arm 48 of the first entrainment device; as shown, the axial arm 48 is retracted, and the clamping plate 45 clamps the adhesive tape 46 to hang the adhesive tape 46 on the mounting seat; then, the two arc-shaped hoop arms 491 of the pipe clamp 49 are released, the plastic pipe 1 is pushed forward by the rear push plate 22, the adhesive tape 46 is pressed and contacted with the first tape cutting device 47 on the mounting seat, the adhesive tape 46 is cut off from the first tape cutting device 47, and one end of the unused adhesive tape 46 is hung on the mounting seat by the clamping plate 45 to return to the initial state.

The bag pulling module 52 clamps the packaging bag 11 and moves towards the pipe clamp under the action of the linear driving mechanism; the bag roll placed on the tension bag placing frame 55 is rotated by a tensile force to continuously output the packing bag 11. After the front part of the plastic pipe 1 is bundled, the plastic pipe 1 is continuously pushed forwards by the rear push plate 22, the front end of the plastic pipe 1 passes through the bag pulling module 52 to enter the plastic bag 11, and the plastic pipe 1 entering the plastic bag 11 is supported by the material supporting frame 62; the middle part and the tail part of the plastic pipe 1 are bound according to the same binding method; after the bundling is finished; the elongated horizontal pushing members 24 are retracted after passing through the bag pulling module 52 to completely push the plastic tube 1 into the plastic bag 1.

As shown in fig. 1 and 25, after the plastic tube 1 is completely pushed into the plastic bag 1, the bag cutting device 56 is moved laterally to cut off the packing bag 11 from the front end of the bag supporting plate 511; meanwhile, the electromagnet 523 of the bag pulling module 52 is powered off, and the movable clamping block 524 loosens the bag clamping inner cylinder 525 under the action of the return spring, so that the packaging bag 11 is loosened, and finally the packaging bag 11 is sleeved outside the plastic tube 1. After the bagging is completed, the vertical moving transmission mechanism 69 of the lifting material supporting unit 6 drives the material supporting frame 62 to move upwards synchronously, and the bag pulling module 52 is reset under the action of the linear driving mechanism to prepare for the next bagging.

As shown in fig. 18, when the plastic tube 1 rises to the bag pushing plates 73, the two bag pushing plates 73 respectively droop a section of the packing bag 11 which is formed by the excess end portion of the plastic tube 1; the plastic pipe 1 is supported by the material supporting frame to continuously move upwards, and stops moving when just passing over the bag pushing plate 73; meanwhile, the movable crank arm 72 rotates to press on the plastic pipe, and the plastic pipe is embraced by the movable crank arm 72 and the material supporting frame 62, so that the position of the plastic pipe is fixed; then, as shown in fig. 26, the bag pushing plate 73 moves axially to fold back an extra section of the packing bag at the end of the plastic tube 1; subsequently, the second tape winding manipulator starts to work; as shown, the tape winding arm 711 drives the tape roll 714 to rotate around the plastic tube 1, the tape is adhered to the outer surface of the packaging bag, and at the same time, as shown in fig. 18, the rotating arm 721 acts to enable the clamping block 724 to release the telescopic arm 723, and the telescopic arm 723 retracts; as shown in fig. 26, the adhesive tape continuously output binds the folded packaging bags together with the plastic tubes 1, so that the mouth of the packaging bag 11 is closed, and the plastic tubes can be effectively prevented from being pulled out of the mouth.

Example two

The difference between this embodiment and the first embodiment is: in this embodiment, the lifting material supporting unit 6 further includes a material supporting frame overturning triggering mechanism, and when the material supporting frame overturning triggering mechanism is triggered, the material supporting frame 62 starts to overturn. The material support frame overturning triggering mechanism is arranged between the bracket and the horizontal rod 68.

As shown in fig. 28 and 29, the material holder turning triggering mechanism in this embodiment includes a crank arm 651, a roller 651, and a blocking guide block 66 for blocking the roller 651 from moving upward and guiding the roller 651 to roll horizontally, one end of the crank arm 651 is fixedly connected to a horizontal rod 68, and the other end of the crank arm 651 is rotatably connected to the roller 651. The blocking guide block 66 is mounted on the carriage, the blocking guide block 66 being higher than the first taping robot.

EXAMPLE III

The difference between this embodiment and the second embodiment is: in this embodiment the blocking guide block 66 is lower than the first taping robot, which avoids making the stand too high. As shown in fig. 31 and 32, in the present embodiment, the blocking guide block 66 is composed of a fixed block 661 and a movable block 662 which can be opened and closed, the movable block 662 is connected with a driving cylinder 663 for driving the movable block to move horizontally, and the fixed block 661 and the driving cylinder 663 are fixedly installed on the bracket. The driving cylinder 663 is mounted on one of the stands 64 through a third mount 665.

When the movable block 662 is folded with the fixed block 661, the roller 651 can be blocked from moving upwards, and when the movable block 662 is separated from the fixed block 661 by a certain distance, the roller 651 can pass between the fixed block 661 and the movable block 662. Further, a reinforcing baffle 664 is fixedly mounted on the support, the reinforcing baffle 664 is located above the movable block 662, and the top surface of the movable block 662 contacts with the bottom surface of the reinforcing baffle 664. When the movable block 662 is pressed upwards by the roller 651, the reinforced baffle 664 can limit and fix the movable block 662, so that the movable block 662 is prevented from being stressed and deviating.

The working principle of the overturning of the material supporting frame in the embodiment is described as follows:

when the material supporting frame 6 supports the plastic pipe 1 and sends the plastic pipe to the strapping unit 7, the movable block 662 is separated from the fixed block 661, so as to prevent the material supporting frame 6 from turning over in the process. When the opening of the packaging bag 11 is sealed, the driving motor 67 rotates reversely, the material supporting frame 62 supports the plastic tube 1 to move downwards, and the movable block 662 is folded with the fixed block 661 after the plastic tube falls below the blocking guide block 66; then, the driving motor 67 rotates forward to drive the material supporting frame 6 to move upwards; when the roller 651 comes into contact with the blocking guide block 66, the magazine 6 is triggered to flip.

The lifting material supporting unit 6 disclosed by the embodiment can directly overturn and convey materials out of the production line, is convenient to use, can avoid setting the support too high, and simultaneously reduces the discharging height of the plastic pipe during discharging.

The utility model can automatically carry out quantitative blanking, automatic labeling, automatic bundling and automatic bagging, can be continuously and automatically generated, does not need human intervention in the whole process, and has high automation degree; the bag opening of the packaging bag can be sealed through the folding mechanism at the end part of the packaging bag and the binding mechanism of the winding belt, so that the pipe or the pipe bundle is effectively prevented from being separated from the bag opening; and finally, the lifting material supporting unit is utilized to directly turn and send the material out of the production line, so that the use is convenient. The whole system has reasonable design and can save the occupied area.

Of course, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and that such changes and modifications are intended to be included within the scope of the appended claims.
