The telescopic slide rail 50 is provided with a mounting frame 51 in a sliding manner, and the mounting frame 51 is used as a mounting platform for each element of the ton bag detection device. A first screw motor 52 is arranged between the detection frame 5 and the installation frame 51, and the installation frame 51 can be pushed to perform linear displacement under the limit of the telescopic slide rail 50 through the action of the first screw motor 52. The middle part of the mounting frame 51 is provided with a central cylinder 53, and the central cylinder 53 is provided with an inserting cylinder 54 in a sliding way. The insertion tube 54 is used for being inserted into the ton bag for strength detection. Specifically, four elongated slots are uniformly formed on the circumference of the bottom of the insertion barrel 54, a connecting rod 55 is hinged in the elongated slots, the front end of the connecting rod 55 is positioned in the insertion barrel 54, the tail end of the connecting rod 55 is hinged with a push plate 56, in this embodiment, in order to ensure that the push plate 56 is always in a vertical state, the tail end of the connecting rod 55 is connected with the middle of the push plate 56, and the bottom of the push plate 56 is provided with a counterweight. The second lead screw motor 57 is installed at the top of the insertion barrel 54, and the second lead screw motor 57 is used for pushing the insertion barrel 54 to perform vertical displacement along the central barrel 53, so that the operation of inserting the insertion barrel into the ton bag for strength detection is realized. A first pressure sensor is mounted between the second lead screw motor 57 and the insertion tube 54. The push rod 58 is slidably mounted in the insertion barrel 54, the bottoms of the push rods 58 are in abutting contact with the front ends of the four connecting rods 55, and the connecting rods 55 can be shifted from a vertical state to a horizontal state by pushing the push rods 58. When the push rod 58 is out of contact with the front end of the link 55, the link 55 returns to a nearly vertical state under the force of gravity. A third lead screw motor 59 is arranged at the top of the push rod 58, and a second pressure sensor is arranged between the push rod 58 and the third lead screw motor 59. The third screw motor 59 is used to drive the push rod 58 to slide in the insertion tube 54. Specifically, the front end of the third lead screw motor 59 is connected with the push rod 58 by a ball head, and the tail end of the third lead screw motor 59 is fixedly connected with the inner wall of the insertion barrel 54, so that the whole formed by the third lead screw motor 59 and the push rod 58 acts along with the insertion barrel 54. When the push rod 58 slides downwards in the insertion barrel 54, the push rod 58 pushes the front end of the connecting rod 55 to gradually open the tail end of the connecting rod 55, at this time, the push plate 56 hinged to the tail end of the connecting rod 55 is always in a vertical state, after the push plate 56 contacts with the ton bag, the push plate 56 tightly supports the inside of the ton bag, and as the third lead screw motor 59 continues to push, after the value of the second pressure sensor exceeds a preset value, the ton bag is proved to meet the transverse strength requirement. The second screw motor 57 is used for pushing the insertion cylinder 54 to slide towards the ton bag, after the bottom of the insertion cylinder 54 contacts the bottom surface of the ton bag, the first pressure sensor starts to measure the value, and when the pressure exceeds the preset value, the ton bag is proved to meet the longitudinal strength requirement. The first screw motor 52, the second screw motor 57 and the third screw motor 59 are all servo motors, and the mounting frame 51, the insertion barrel 54 and the push rod 58 can be precisely displaced under the control of the control system.

Specifically, the two sides of the top of the lifting frame 32 are provided with grooves 34, and the grooves 34 are T-shaped grooves. Two sides of the bottom of the mounting frame 51 are provided with bosses corresponding to the slots 34, and the bosses are in sliding fit with the slots 34. When the lifting wheel set 42 triggers the detection sensor, the control system receives the signal to control the lifting line 1 to stop running, and the lifting frame 32 stops at the position of being in butt joint with the mounting frame 51. And then the control system controls the first screw motor 52 to act so as to push out the mounting frame 51, and the boss on the mounting frame 51 is in butt joint with the slot 34, so that the mounting frame 51 and the lifting frame 32 are relatively fixed, and most of pressure is born by the mounting frame 51 during strength detection, so that damage to the lifting line 1 is avoided.

More specifically, the number of suspension sensors is N, the suspension wheel sets 42 circulate through the suspension positions in the order of 1-N, and when the number N of suspension sensors are triggered by the same suspension wheel set 42 in turn, only the triggering of the suspension sensors whose arrangement positions are consistent with the order of the suspension wheel sets 42 is effective triggering, so that the conveying line is suspended. That is, after the suspension line 1 is started, after all suspension sensors are triggered by the first passing suspension frame 32, only the signal of the first triggered suspension sensor is received by the control system to control the suspension line to stop running, the suspension frame 32 is stopped at the first suspension sensor, and after all suspension sensors are triggered by the second passing suspension frame 32, only the signal of the second triggered suspension sensor is received by the control system to control the suspension line to stop running, and the suspension frame 32 is stopped at the second suspension sensor.

Taking the example of mounting 3 lifting frames 32 on the lifting line 1, this represents one week of running of the lifting line 1, and sampling inspection is performed on 3 ton bags. When the hoisting line 1 runs, the running program of each component is as follows according to the time sequence: the hoisting rope 3 is driven by the driving motor 25 to circularly run, when the hoisting wheel set 42 triggers the hanging sensor of the hanging position, the hanging sensor transmits the model to the control system, the control system controls the driving motor 25 to stop acting, and at the moment, a worker must hang the next ton of bags at the bottom of the hoisting frame 32, and the hoisting line 1 is considered to be started. When the lifting frame 32 reaches the detection position through the conveying of the lifting line 1 to trigger the detection sensor, the control system controls the driving motor 25 to stop acting, controls the first screw motor 52 to stretch, pushes the mounting frame 51 out to be in butt joint with the lifting frame 32, and the inserting cylinder 54 is located just above the top opening of the ton bag. The control system then controls the second lead screw motor 57 to extend to insert the insertion cartridge into the interior of the ton bag, and then controls the third lead screw motor 59 to extend so that the push rod 58 drives the link 55 to move from the vertical state to the horizontal state until the push plate 56 contacts the inner wall of the ton bag. When the value detected by the second pressure sensor exceeds the set value, the transverse strength of the ton bag is proved to meet the requirement. The control system then controls the third screw motor 59 to retract a certain distance to enable the push plate 56 to loosen the support for the interior of the ton bag, then controls the second screw motor 57 to extend a certain distance to reselect the detection position in the ton bag, and then controls the third screw motor 59 to extend to enable the push rod 58 to drive the connecting rod 55 to transfer from the vertical state to the horizontal state until the push plate 56 contacts the inner wall of the ton bag, and intensity detection at the position is completed. And when the transverse strength of the ton bag is detected, selecting the position of 2-4 in the height direction of the ton bag for detection. Finally, after the transverse strength detection of multiple points is completed, the second lead screw motor 57 is controlled by the control system to continuously push the insertion barrel 54 to extend towards the interior of the ton bag until the bottom of the insertion barrel 54 contacts the bottom surface of the ton bag, at the moment, the push plate 56 is driven by the connecting rod 55 to relatively open to prop open the inner wall of the ton bag for a certain space, the bottom of the insertion barrel 54 is pushed against the ton bag along with the pushing of the second lead screw motor 57, four handles of the ton bag are straightened until the value of the first pressure sensor reaches a set value, the vertical strength of the ton bag is proved, then the controller controls the third lead screw motor 59 to reset, the connecting rod 55 is driven by the push rod 58 to be in a relatively vertical state, the second lead screw motor 57 is reset to drive the insertion barrel 54 to slide out of the ton bag, and the first lead screw motor 52 is reset to drive the mounting frame 51 to be separated from the butt joint with the lifting frame 32. Then the control system controls the hoisting line 1 to start continuously, and the packing position is used for completing the work of taking down, folding and packing ton bags continuously.

More specifically, the detection sensor of the detection position has a higher priority than the suspension sensor of the suspension position, and when the detection sensor is triggered to stop the operation of the suspension line 1, the suspension line cannot be restarted at the suspension position by stepping on the switch.

More specifically, the device is provided with a paint spraying mechanism 6 for spraying ton bags at the detection position. When the detected ton bags do not meet the requirement of transverse strength or the requirement of vertical strength, the control system controls the air injection mechanism 6 to start, marks the unqualified ton bags, and facilitates separation of packing positions.

When the spot inspection is carried out, after the number of the ton bags of the same day exceeds 5, all ton bags need to be fully inspected.
