[0058] In this embodiment, the main loading process is as follows:

[0059] A loading method of a packaging bag loading system is controlled by a robot main control cabinet, and the following steps are taken:

[0060] S1, the vehicle to be loaded is positioned, and the forklift places the packaging bag 16 on the tray 1201 of the feeding device 12.

[0061] S2, after the data acquisition device 15 placed on the top beam acquires the length and related vehicle model data of the vehicle, the data are fed back to the robot main control cabinet 7.

[0062] S3, the feeding device 12 stops rising after conveying the packaging bag 16 upward to a suitable position for the bag taking device 13 to work;

[0063] S4, the negative pressure fan inhales, the suction cup 1 in the bag taking device 13 sucks a layer of packaging bag, and then rotates to the position above the loading position.

[0064] S5, the negative pressure fan 804 stops inhaling, and the air compressor 805 supplies air to place (blow off) the packaging bag at the specified position; in this way, the bag taking and placing process of the robot 5 is completed; at this time, the tray 1201 in the feeding device 12 is lifted by the height of one packaging bag 16 under the instruction control and the driving of the driving part 1207, so as to facilitate the robot 5 to grasp the next packaging bag 16.

[0065] ​S6, after the first robot finishes taking the bag, an instruction is immediately sent to control the second robot to perform the action of taking the packaging bag, during the process of the first robot completing the bag placing, the second robot finishes taking the bag, then the third robot receives the instruction and prepares to take the bag; the cycle is as follows: the bag placing action of the first robot 5 is completed, and then the bag taking action of the second robot is completed; the four robots perform the action in sequence.

[0066] Specifically, the robot 5 is composed of a rotating base 501 installed on the base 1 or the ground, a vertical arm 502, a horizontal arm 503, a swing arm 504, a first swing arm 505, a second swing arm 506, etc., wherein the horizontal arm 503, the swing arm 504, the first swing arm 505 and the second swing arm 506 form a parallelogram structure, when the swing arm 504 is lifted upward through the second swing arm 506, the packaging bag 16 sucked by the bag taking device 13 is lifted from the tray 1201 of the feeding device 12, after setting the rotation angle, the swing arm 504 is lowered to place the packaging bag 16 on the appropriate position of the waiting loading position 4, and the next packaging bag 16 is also cycled in the same way.

[0067] The rotating action of the bag taking device 13 is actually placed according to the data collected by the data collection device 15, and the packaging bags 16 are arranged and placed on each layer of the tray 1201 in the material position warehouse 1204, and the bag taking device 13 can realize different direction rotation to suck the bag body under the control of the robot 5 according to the data collected by the data collection device 15; because the conversion device 14 is adopted, no matter how the rotating action of the bag taking device 13 is, the winding phenomenon caused by the negative pressure air pipe 802 will not occur, and the working efficiency is high.

[0068] Among them, as shown in the specific structure of Figure 8 The suction cups 1306 are arranged as five, three are arranged longitudinally on the upper surface, and two are arranged transversely on the lower surface, and the total length of the three longitudinally arranged packaging bags is equal to the total length of the two transversely arranged packaging bags, wherein the packaging bags 16 are transported on the forklift, and the arrangement form of each layer is as follows: the odd layers are placed as shown in the figure, and the even layers are placed in the opposite way of the odd layers, that is, two transversely arranged packaging bags are placed on the upper surface, and three longitudinally arranged packaging bags are placed on the lower surface, and this odd-even stacking method is beneficial to stable placement.

[0069] In this embodiment, the conversion device 14 adopted can realize the suction and placement of packaging bags arranged and placed in different ways, when the odd layers, the bag taking device 13 connected with the conversion device 14 is rotated by 90 degrees under the driving of the robot 5 to realize the bag taking and placing process, when the even layers, the bag taking device 13 needs to be converted by 180 degrees to realize the bag taking and placing process, therefore, the embodiment of the present application is novel in design, can adapt to the stacking and transfer requirements of packaging bags 16 arranged and placed in different ways, and has high efficiency.

[0070] The action process is controlled by the PLC controller placed in the robot control cabinet 7, and the action time difference of the robots 5 located on the same side of the vehicle body is only 3-5 seconds. The robots 5 located on the other side of the vehicle body also have an action time difference of only 3-5 seconds under the control of the PLC, that is, the action time difference of the robots arranged on both sides is only 3-5 seconds, which is beneficial to the overall rotation of the robots 5 and the bag taking device 13 and does not produce interference. The base of the robot 5 rotates about 90 degrees, and the bag taking device 13 rotates different number of times according to the specific position of the placed bags. Each robot 5 first sucks 5 packaging bags 16 in the first tray position 11 through the suction cup 1306, and then sucks the packaging bags 16 in the second tray position 9. Since the descending height of the cross arm 503 of the robot 5 is a set distance or height, after one layer of packaging bags 16 on each tray position is taken away, the remaining packaging bags 16 on the tray 1201 are lifted by one layer under the drive of the driving part 1207. Since the motor in the driving part 1207 is provided with a brake device, the action of stopping and lifting can be realized until all the packaging bags on the same tray 1201 are sucked. About 8-10 layers of packaging bags 16 are arranged on the tray 1201 in the material position warehouse 1204. The length of the vehicle compartment in the embodiment is about 14.8 meters. When the robot 5 on one side of the vehicle body acts, a signal is sent to the robot 5 on the other side. When the forklift places the material on the tray 1201, the weighing sensor on the tray 1201 senses the weight, and then the driving part 1207 is started to rise under the driving of the ring chain 1206. When the set height is reached, the upper limit block 1210 is touched by the upper collision plate 1211, and the tray 1201 stops rising. At this time, the tray 1201 has been lifted into position, the PLC controller in the robot main control cabinet 7 sends a command, the robot 5 drives the bag taking device 13 to act to take bags, the robot 5 rotates to a set angle, and then the packaging bags 16 are placed in the vehicle compartment of the waiting loading position 4. After the placement is completed, the negative pressure fan 804 stops the suction action. The electromagnetic valve acts, and the air compressor 805 supplies air. The air supplied by the air compressor 805 makes the suction cup 1206 separate from the packaging bag 16, and the process of taking and placing one layer of five packaging bags 16 by the robot 5 is completed.

[0071] The advantage of the embodiment is that the four groups of robots 5 can act in sequence and do not interfere with each other in space, and the efficiency is obviously improved.

[0072] In the utility model, the changes of data made on the basis of the same design concept and protection scope under the premise that the specific conditions listed in the above embodiments are not limited, and all are considered to be within the protection scope of the utility model.
