[0031] Refer to Figure 1 And Figure 2 , an anti-overlapping bag system applied to a powder emulsion explosive conveying line, including an upper belt 1, a lower belt 2, a first gripper assembly 6-1, a second gripper assembly 6-2 and a movable roller assembly 8. The upper belt 1 is installed above the lower belt 2. A first sensor 7-1 is arranged at the outlet of the upper belt 1. The lower belt 2 includes a conveying belt, a curved landslide plate 4 and a guide plate 5. The conveying belt is sequentially connected to the curved landslide plate 4 and the guide plate 5. The material bags on the conveying belt directly fall onto the lower belt 2 under the action of the curved landslide plate 4 and the guide plate 5. A second sensor 7-2 is arranged below the outlet of the upper belt 1 corresponding to the lower belt 2. The first gripper assembly 6-1 and the second gripper assembly 6-2 are arranged on one side of the second sensor 7-2 close to the inlet of the lower belt 2. The first gripper assembly 6-1 and the second gripper assembly 6-2 are respectively installed on both sides of the lower belt 2 along the material transmission direction. The movable roller assembly 8 is arranged on one side of the second sensor 7-2 close to the outlet of the lower belt 2. The movable roller assembly 8 is installed above the lower belt 2.

[0032] In this embodiment, both the first sensor 7-1 and the second sensor 7-2 are installed on the brackets of the corresponding belts. Through the first sensor 7-1, the arrival and departure of the material bags at a specified position on the upper belt 1 can be monitored. Through the second sensor 7-2, the arrival and departure of the material bags at a specified position on the lower belt 2 can be monitored, providing start and reset signals for the operation of the first gripper assembly 6-1 and the second gripper assembly 6-2.

[0033] Refer to Figure 3 , the movable roller assembly 8 includes a fixed bracket 8-1 and a movable roller 8-2. The fixed bracket 8-1 is fixedly installed above the lower belt 2. Lifting grooves are formed on both sides of the fixed bracket 8-1. The movable roller 8-2 is rotatably installed inside the lifting grooves. The lowest height between the movable roller 8-2 inside the lifting grooves and the lower belt 2 is the thickness of one material bag, and the highest height between the movable roller 8-2 inside the lifting grooves and the lower belt 2 is greater than the thickness of two material bags.

[0034] In this embodiment, when the upper material bag 3-1 directly overlaps the lower material bag 3-2, and the upper material bag 3-1 is in front and the lower material bag 3-2 is behind, an overlapping bag situation occurs. A lifting arc surface with a curvature is formed at the front part of the upper material bag 3-1. When the upper material bag 3-1 contacts the movable roller 8-2, under the action of the lifting arc surface, the movable roller 8-2 is pushed to the top of the lifting groove, and in this case, the overlapping bag directly passes through;

[0035] When the upper material bag 3-1 is directly placed on the lower material bag 3-2, and the upper material bag 3-1 is behind and the lower material bag 3-2 is in front, resulting in an overlapping bag situation, a lifting arc surface with a curvature is formed at the rear of the upper material bag 3-1. When the upper material bag 3-1 contacts the movable roller 8-2, the lifting arc surface cannot function. Under the blocking action of the movable roller 8-2, the upper material bag 3-1 and the lower material bag 3-2 are directly separated.

[0036] Refer to Figure 4 , both the first gripper assembly 6-1 and the second gripper assembly 6-2 are composed of grippers 6-3 and a first cylinder 6-4 arranged oppositely. The gripper 6-3 is connected to the telescopic end of the piston rod of the first cylinder 6-4, and the fixed end of the cylinder barrel of the first cylinder 6-4 is connected to the bracket of the lower belt 2. The side of the gripper 6-3 close to the inside of the lower belt 2 is a curved surface, and the surface is wrapped with rubber, which not only increases the friction force when contacting the material bag, can quickly realize the clamping function, but also reduces the impact force of the clamping action on the packaging bag.

[0037] In this embodiment, when the first sensor 7-1 monitors the arrival of the upper material bag 3-1 and the lower material bag 3-2 arrives as monitored by the second sensor 7-2 before the upper material bag 3-1 has completely passed, the first cylinder 6-4 operates, and the gripper 6-3 clamps the lower material bag 3-2. When the first sensor 7-1 monitors that the upper material bag 3-1 has completely passed, the first cylinder 6-4 resets, and the lower material bag 3-2 continues to be conveyed forward under the action of the lower belt 2.

[0038] On one side of the movable roller assembly 8 close to the outlet of the lower belt 2, a left guiding bag baffle 8-3 and a right guiding bag baffle 8-4 are provided. The left guiding bag baffle 8-3 and the right guiding bag baffle 8-4 are respectively connected to both sides of the bracket of the lower belt 2. Both the left guiding bag baffle 8-3 and the right guiding bag baffle 8-4 are inclined towards the inside of the lower belt 2 and are symmetric about the center line of the lower belt 2. The outlet width formed by the left guiding bag baffle 8-3 and the right guiding bag baffle 8-4 is adapted to the width of the material bag.

[0039] In the embodiment, through the action of the left guiding bag baffle 8-3 and the right guiding bag baffle 8-4, the process of correcting the posture of the material bag is carried out.

[0040] Refer to Figure 5, The anti-overlapping bag system applied to the powder emulsion explosive conveying line further includes a vacuum bag suction assembly 10, a bag suction belt 11 and a converging belt 12. A bag suction belt 11 is arranged at the outlet of the lower belt 2, and the converging belt 12 is arranged on the side of the bag suction belt 11 away from the lower belt 2. A weighing assembly 9 is installed below the bag suction belt 11, and the vacuum bag suction assembly 10 is installed above the bag suction belt 11. A fourth sensor 7-4 is arranged at the inlet of the bag suction belt 11, and a fifth sensor 7-5 is arranged at the outlet of the bag suction belt 11.

[0041] The vacuum bag suction assembly 10 includes a connecting frame 10-1, a fixing plate 10-2, a second cylinder 10-3 and a suction cup 10-4. The fixing plate 10-2 is arranged above the bag suction belt 11. Both sides of the fixing plate 10-2 are connected to the side brackets of the bag suction belt 11 through the connecting frame 10-1. The suction cup 10-4 is arranged on the side of the fixing plate 10-2 close to the bag suction belt 11. The suction cup 10-4 is connected to the fixing plate 10-2 through the second cylinder 10-3. A damper is arranged at the connection between the suction cup 10-4 and the second cylinder 10-3, so that the suction cup 10-4 has a buffering function when contacting the material bag.

[0042] In this embodiment, since the overlapping situation where the upper material bag 3-1 is behind and the lower material bag 3-2 is in front has been separated by the movable roller assembly 8, when the gripper assembly fails, the upper material bag 3-1 is in front and the lower material bag 3-2 is behind and enters the bag suction belt 11. After the fourth sensor 7-4 detects the arrival of the material bag and the material bag completely passes the fourth sensor 7-4, and the fifth sensor 7-5 monitors the arrival of the material bag. When the weight obtained by the weighing assembly 9 is greater than the preset value, the bag suction belt 11 stops, and the second cylinder 10-3 drives the suction cup 10-4 to adsorb and lift the upper material bag 3-1. When the weight of the weighing assembly 9 does not exceed the preset value, the bag suction belt 11 continues to run. When the lower material bag 3-2 completely passes the fifth sensor 7-5, the second cylinder 10-3 drives the suction cup 10-4 to descend to a specified height and then the suction cup 10-4 stops working and resets. The upper material bag 3-1 is conveyed to the converging belt 12 to complete the separation of the overlapping bags.

[0043] A third sensor 7-3 is arranged on one side close to the outlet of the lower belt 2. The installation heights of the left bag guiding baffle 8-3 and the right bag guiding baffle 8-4 are different from that of the third sensor 7-3. The third sensor 7-3 is used to monitor whether the material bag smoothly passes through the shaping mechanism formed by the left bag guiding baffle 8-3 and the right bag guiding baffle 8-4.

[0044] To more clearly illustrate the solution and effect of this embodiment, an example is given in combination with the attached drawings:

[0045] When the gripper assembly works normally:

[0046] The upper material bag 3-1 is conveyed on the upper belt 1, and the lower material bag 3-2 is conveyed on the lower belt 2. Since it takes time for the material to be bagged, the material bags are conveyed at a certain interval after being loaded onto the conveyor belt. When the upper material bag 3-1 is conveyed to the outlet of the upper belt 1, it will fall onto the lower belt 2;

[0047] When the first sensor 7-1 monitors the arrival of the upper material bag 3-1 and the upper material bag 3-1 has completely passed, and the second sensor 7-2 does not monitor the arrival of the lower material bag 3-2, the gripper assembly does not work;

[0048] When the second sensor 7-2 monitors the arrival of the lower material bag 3-2 and the lower material bag 3-2 has completely passed, and the first sensor 7-1 does not monitor the arrival of the upper material bag 3-1, the gripper assembly does not work;

[0049] When the first sensor 7-1 monitors the arrival of the upper material bag 3-1 and the upper material bag 3-1 has not completely passed, and the second sensor 7-2 monitors the arrival of the lower material bag 3-2, the first cylinder 6-4 works, and the gripper 6-3 clamps the lower material bag 3-2. When the first sensor 7-1 monitors that the upper material bag 3-1 has completely passed, the first cylinder 6-4 resets, and the lower material bag 3-2 continues to be conveyed forward under the action of the lower belt 2;

[0050] When the second sensor 7-2 monitors the arrival of the lower material bag 3-2 and the lower material bag 3-2 has not completely passed, and the first sensor 7-1 monitors the arrival of the upper material bag 3-1, the gripper assembly does not work. The upper material bag 3-1 directly rests on the lower material bag 3-2, with the upper material bag 3-1 at the back and the lower material bag 3-2 at the front, resulting in an overlapping package situation. A lifting arc surface with a curvature is formed at the rear of the upper material bag 3-1. When the upper material bag 3-1 contacts the movable roller 8-2, the lifting arc surface cannot function, and the upper material bag 3-1 is blocked by the movable roller 8-2, causing the upper material bag 3-1 and the lower material bag 3-2 to separate directly.

[0051] When the gripper assembly fails:

[0052] When the upper material bag 3-1 directly rests on the lower material bag 3-2, with the upper material bag 3-1 at the back and the lower material bag 3-2 at the front, resulting in this overlapping package situation, the upper material bag 3-1 and the lower material bag 3-2 can be directly separated under the blocking action of the movable roller 8-2;

[0053] When the upper material bag 3-1 is directly placed on the lower material bag 3-2, and the upper material bag 3-1 is in front and the lower material bag 3-2 is behind, resulting in an overlapping bag situation, a lifting arc surface with a curvature is formed at the front of the upper material bag 3-1. When the upper material bag 3-1 contacts the movable roller 8-2, under the action of the lifting arc surface, the movable roller 8-2 is pushed to the top of the lifting groove. In this case, the overlapping bag directly enters the suction bag belt 11. After the fourth sensor 7-4 detects the arrival of the material bag and the material bag completely passes the fourth sensor 7-4, the fifth sensor 7-5 monitors the arrival of the material bag. When the weight obtained by the weighing assembly 9 is greater than the preset value, the suction bag belt 11 stops, and the second cylinder 10-3 drives the suction cup 10-4 to adsorb and lift the upper material bag 3-1. When the weight of the weighing assembly 9 does not exceed the preset value, the suction bag belt 11 continues to run. When the lower material bag 3-2 completely passes the fifth sensor 7-5, the second cylinder 10-3 drives the suction cup 10-4 to descend to a specified height, and then the suction cup 10-4 stops working and resets. The upper material bag 3-1 is conveyed to the converging belt 12 to complete the separation of the overlapping bags.
