Example two

The difference between this embodiment and the first embodiment is that: the lifting and lowering 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 overturning. The carriage flip-flop mechanism is disposed between the bracket and the horizontal bar 68.

As shown in fig. 27, 28 and 29, the turning trigger mechanism of the material supporting frame in this embodiment includes a lever 651, a roller 651, and a blocking guide block 66 for blocking upward movement of the roller 651 and guiding horizontal rolling of the roller 651, one end of the lever 651 is fixedly connected with the horizontal rod 68, and the other end of the lever 651 is rotatably connected with the roller 651. The blocking guide block 66 is mounted on the bracket, the blocking guide block 66 being higher than the taping robot. The sliding block 63 is rotatably connected with the horizontal rod 68 in the embodiment; when the roller 651 moves up to a certain height along with the horizontal rod 68, the roller 651 is blocked by the blocking guide block 66, the lever 651 drives the horizontal rod 68 to rotate, and the horizontal rod 68 drives the material supporting frame 62 to turn over.

When the tray 62 is flipped to the final position, the tray arm 622 is raised above the hanger arm 621 such that the items on the tray arm 622 fall from the tray arm 622 by their own weight.

To guide the material to fall, a discharge guide slope 641 is provided at the top of the stand, and the top surface of the hanging arm 621 is parallel to the discharge guide slope 641 when the carriage 62 is turned to the final position.

The working principle of the turning of the material supporting frame in this embodiment is described below with reference to fig. 27 to 32:

In example 1, after the mouth of the package 11 is closed, the plastic tube 1 is still held by the holding frame 62. The driving motor 67 continues to run to drive the material supporting frame 6 to move upwards;

As shown in fig. 29, when the roller 651 is moved up to a certain height along with the horizontal bar 68, the roller 651 is blocked by the blocking guide block 66 and cannot continue to move upward; at this time, the horizontal rod 68 continues to ascend, the roller 651 moves horizontally along the blocking guide block 66, the crank arm 65 rotates to drive the horizontal rod 68 to rotate, and then the three material supporting frames 62 are driven to synchronously rotate for a certain angle;

As shown in fig. 30 and 31, the horizontal rod 68 continues to ascend, the crank arm 65 continues to rotate, and then the material supporting frame 62 is driven to rotate continuously;

As shown in fig. 31 and 32, when the horizontal rod 68 rises to a certain height, the roller 651 will be pulled to move horizontally in the opposite direction, and the crank arm 65 continues to rotate, so as to drive the material supporting frame 62 to rotate continuously; when the horizontal bar 68 moves to the top dead center, as shown in fig. 32, the carriage 62 is turned to the final position, and the carriage arm 622 is higher than the hanging arm 621, and the plastic tube 1 rolls down the discharge guide slope 641 by its own weight, thereby turning over the plastic tube from one side of the rack to the other side of the rack. A loading cart 60 can be placed on the unloading side of the support in advance, so that the unloaded plastic pipes 1 are directly stacked on the loading cart 60, and are convenient to transport out.

The lifting material supporting unit 6 disclosed in the embodiment can directly turn and send materials out from the production line, is convenient to use, and can save the occupied area.

Example III

The difference between this embodiment and the second embodiment is that: the blocking guide block 66 in this embodiment is lower than the taping robot so that the stand is not made too high. As shown in fig. 33 to 37, the blocking guide block 66 in this embodiment is composed of a openable and closable fixed block 661 and a movable block 662, the movable block 662 is connected to a driving cylinder 663 for driving the movable block 662 to move horizontally, and the fixed block 661 and the driving cylinder 663 are fixedly mounted on a bracket. The drive cylinder 663 is mounted to one of the uprights 64 by a mounting base 665.

The roller 651 is blocked from ascending when the movable block 662 is closed with the fixed block 661, and the roller 651 is passed between the fixed block 661 and the movable block 662 when the movable block 662 is separated from the fixed block 661 by a certain distance. Further, a reinforcing baffle 664 is fixedly installed on the bracket, the reinforcing baffle 664 is located above the movable block 662, and the top surface of the movable block 662 is in contact with the bottom surface of the reinforcing baffle 664. When the movable block 662 is pressed upwards by the roller 651, the reinforcing baffle 664 can limit and fix the movable block 662, so that the movable block 662 is prevented from being biased by the force.

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

When the material supporting frame 6 supports the plastic tube 1 to the taping unit 7, the movable block 662 is separated from the fixed block 661 to avoid the overturning of the material supporting frame 6 in the process.

When the bag mouth of the packaging bag 11 is closed, the driving motor 67 is reversed, the material supporting frame 62 supports the plastic pipe 1 to move downwards, and after the plastic pipe descends below the blocking guide block 66, the movable block 662 is closed with the fixed block 661;

then, the driving motor 67 rotates forward to drive the material supporting frame 6 to move upwards; when the roller 651 contacts the blocking guide block 66, the carrier 6 is triggered to turn over.

The lifting material supporting unit 6 disclosed in the embodiment can directly turn and send materials out from the production line, is convenient to use, and can avoid setting the support to be too high.

The vertical movement transmission 69 is provided with at least two side by side, including but not limited to 3-5. The driven wheel 632 is arranged on the bracket, and the driving wheel 631 is arranged on the horizontal transmission shaft 61; the timing belt is wound around the driving pulley 631 and the driven pulley 632. Of course, a chain may be used instead of the timing belt.

The horizontal bar 68 is fixedly connected with a chain or a timing belt of each vertical movement transmission mechanism 69. The horizontal rod 68 is fixedly connected with a sliding block 63, the bracket is provided with a vertical sliding rail 633 which is matched with the sliding block 63, and the sliding block 63 is in sliding connection with the vertical sliding rail 633. At least two sliding blocks 63 are arranged on the horizontal rod 68 at intervals.

The material supporting frames 62 are mounted on the horizontal rods 68, and at least two material supporting frames 62 are arranged at intervals. Preferably, the number of the material supporting frames 62 is equal to that of the vertical movement transmission mechanisms 69, and one material supporting frame 62 is arranged beside each vertical movement transmission mechanism 69; the number of the sliders 63 is equal to the number of the vertical movement transmission mechanisms 69.

The stock rest 62 is integrally manufactured.

The material supporting frame 62 is mounted on the horizontal rod 68 through two hanging arms 621, and the material supporting frame 62 is positioned between the two hanging arms 621. The lower end of the hanging arm 621 is fixedly connected with the horizontal rod 68, and the upper end of the hanging arm 621 is rotatably connected with the material supporting frame 62.

As shown in fig. 38, 39 and 40, in a natural state, the center of gravity of the material supporting frame is deviated to the material supporting arm side, so that the material supporting frame 62 tends to rotate downwards around the switching position of the hanging arm 621. The interference portion interferes with the horizontal bar 68, and the force applied to the pallet 62 by the horizontal bar 69 counteracts the eccentric force of the pallet 62, thereby maintaining the balance of the pallet 62.

The lifting material supporting unit 6 in the embodiment can also be provided with a material supporting frame overturning triggering mechanism, and the material supporting frame overturning triggering mechanism is arranged between the bracket and the material supporting frame 62; when the carriage flip-flop is triggered, the continuously ascending horizontal bar 68 will drive the carriage 62 to flip. Specifically, the carriage overturning triggering mechanism includes a roller 651 provided on the carriage 62, and a blocking guide block 66 for blocking upward movement of the roller 651. The roller 651 is rotatably arranged at the free end of the crank arm 651; the blocking guide block 66 is mounted on the bracket. A discharge guide slope 641 is provided at the top of the stand.

As shown in fig. 40, when the roller 651 is moved up to a certain height along with the carriage 62, the roller 651 is blocked by the blocking guide block 66 and cannot be moved further upward; at this time, the material supporting frames 62 continue to ascend along with the horizontal rods 68, so that the material supporting frames 62 are forced to rotate around the switching position of the hanging arms 621, and then the three material supporting frames 62 start to synchronously overturn;

As shown in fig. 41, the material supporting frame 62 continues to ascend and turn over; when moving to the top dead center, the carriage 62 is turned to the final position, and the carriage arm 622 is positioned at the highest position of the carriage 62, and the plastic tube 1 rolls down the discharge guide slope 641 under the action of gravity, so that the plastic tube 1 is turned from one side of the bracket to the other side of the bracket.
