[0038] The utility model provides a ton bag grabbing detection device, which includes a conveying mechanism 30, two driving components 10, two grabbing mechanisms 20 and two detection mechanisms 40. The two driving components 10 are relatively arranged on the conveying mechanism 30; each of the driving components 10 is respectively provided with a grabbing mechanism 20, and the two driving components 10 are used to drive the two grabbing mechanisms 20 to move toward or away from each other; each of the grabbing mechanisms 20 is correspondingly provided with a detection mechanism 40, the grabbing mechanism 20 is used to clamp the ton bag and drive the ton bag to move on the conveying mechanism 30, and the detection mechanism 40 is used to detect whether the grabbing mechanism 20 clamps the ton bag in place.

[0039] Please refer to Figure 1 A plurality of conveying stations are arranged along the conveying path of the conveying mechanism 30, such as a first station, a second station, a third station, etc. Different stations have different functions. For example, the first station can be used to supply ton bags, the second station can be used to load materials into ton bags, the third station can be used to package ton bags, and so on.

[0040] The driving assembly 10 is movably disposed on the conveying mechanism 30 , and two driving assemblies 10 are disposed opposite to each other, and each driving assembly 10 is provided with a grabbing mechanism 20 .

[0041] The driving end of the driving assembly 10 is connected to the grabbing mechanism 20 , so that when the driving end of the driving assembly 10 moves, it can drive the grabbing mechanism 20 to move synchronously.

[0042] By adjusting the installation position and installation direction of the driving assembly 10, the driving ends of the two driving assemblies 10 are opposite to each other, so that in the process of driving the grasping mechanism 20 to move, the two grasping mechanisms 20 are driven to move toward or away from each other.

[0043] When picking up bulk bags, please refer to Figure 2 and Figure 3 , the driving assembly 10 moves to the corresponding position of the ton bag, and makes the ton bag be located between the two grabbing mechanisms 20. The two grabbing mechanisms 20 move toward each other until they abut against the left and right sides of the ton bag, thereby achieving the grabbing of the ton bag.

[0044] When the big bag is released, the two gripping mechanisms 20 move away from each other and detach from the big bag, allowing the big bag to flow into the next process.

[0045] In the process of grabbing and releasing the ton bag, the ton bag is detected by the detection mechanism 40. When the grabbing mechanism 20 performs the grabbing operation, the detection mechanism 40 detects the existence of the ton bag, indicating that the grabbing is in place; when the existence of the ton bag is not detected, it means that the grabbing is not successful, and the grabbing mechanism 20 can be controlled to grab again. Alternatively, an alarm can be given by connecting an external buzzer, a prompt light, etc., so that the on-site operator can handle it in time.

[0046] The two grabbing mechanisms 20 are arranged as a group on both sides of the conveying mechanism 30, and cooperate with each other to clamp the left and right sides of the ton bag.

[0047] According to needs, multiple groups of the grasping mechanisms 20 can be set on the conveying mechanism 30, and one group of the grasping mechanisms 20 can be arranged to move back and forth between different workstations to achieve interaction between the multiple groups of the grasping mechanisms 20, thereby improving the overall production rhythm and production efficiency.

[0048] It can be understood that when the number of the grasping mechanisms 20 increases, the number of the driving components 10 and the detection mechanisms 40 should also increase accordingly to meet the grasping and detection requirements of the grasping mechanisms 20.

[0049] In the technical solution of the utility model, the driving assembly 10 and the grabbing mechanism 20 grab the ton bag, and the conveying mechanism 30 drives the ton bag to be transported and moved. After the grabbing mechanism 20 completes the grabbing action of the ton bag, the grabbing mechanism 20 is detected by the detection mechanism 40 to determine whether the grabbing mechanism 20 grabs in place, thereby ensuring the stability of the ton bag during transportation and movement. The material can be loaded normally, and the feeding efficiency is improved.

[0050] Specifically, the driving assembly 10 includes a movable seat and a first driving member 11, and the movable seat is movably arranged on the conveying mechanism 30; the first driving member 11 is arranged on the movable seat, and the grabbing mechanism 20 is arranged on the first driving member 11, and the first driving member 11 is used to drive the grabbing mechanism 20 to telescopically move, and the driving direction of the first driving member 11 is perpendicular to the conveying mechanism 30.

[0051] The movable seat is provided with a power device, such as a motor, or a linear module, etc. When the movable seat moves, it drives the first driving member 11 to move on the transmission mechanism 30 .

[0052] The first driving member 11 may be a cylinder, connected to the grabbing mechanism 20 via a piston rod. The grabbing mechanism 20 is extended and retracted by the piston rod. When the first driving members 11 on both sides are extended at the same time, the two grabbing mechanisms 20 move toward each other, and when the first driving members 11 on both sides are retracted at the same time, the two grabbing mechanisms 20 move away from each other.

[0053] In this embodiment, the conveying mechanism 30 adopts a guide rail 31 for transportation. Two guide rails 31 are arranged oppositely and in parallel, and each guide rail 31 is provided with a driving assembly 10. In order to facilitate grasping, the driving direction of the first driving member 11 is set to be perpendicular to the conveying direction of the conveying mechanism 30. During grasping and transportation, the tonnage is located between the two guide rails 31, saving space and reducing the equipment footprint.

[0054] Specifically, the grasping mechanism 20 includes a grasping component 21, and the grasping component 21 includes a shell 211, a fixed plate 212, a second driving member 213 and a movable plate 214, the shell 211 is arranged on the first driving member 11; the fixed plate 212 is arranged on the shell 211; the second driving member 213 is arranged in the shell 211; the movable plate 214 is connected to the second driving member 213, and the second driving member 213 is used to drive the movable plate 214 to move toward or away from the fixed plate 212.

[0055] One end of the shell 211 is connected to the first driving member 11, and the other end extends to the first driving member 11 on the other side and is connected to the fixing plate 212. One end of the fixing plate 212 is connected to the shell 211, and the other end extends to a side away from the shell 211.

[0056] The movable plate 214 is disposed opposite to and on the same side as the fixed plate 212. The second driving member 213 is installed in the housing 211. Under the driving of the second driving member 213, the movable plate 214 can move toward or away from the fixed plate 212.

[0057] The movable plate 214 and the fixed plate 212 extend toward the first driving member 11 on the other side so as to contact with the ton bag between the two guide rails 31 to achieve clamping.

[0058] Correspondingly, the edge of the ton bag has a protruding edge for the movable plate 214 to clamp with the fixed plate 212. A bag support device is arranged upstream of the ton bag grabbing and detecting device to ensure that the ton bag has a certain shape when it flows into the ton bag grabbing and detecting device, so as to facilitate the fixed plate 212 and the movable plate 214 to clamp the edge.

[0059] During the clamping operation, the movable plate 214 moves toward the fixed plate 212, abuts against the edge of the ton bag, and continues to move until it abuts against the fixed plate 212, thereby clamping the ton bag. Conversely, during the loosening operation, the movable plate 214 moves away from the fixed plate 212, thereby loosening the clamped edge of the ton bag.

[0060] Specifically, the detection mechanism 40 includes a transmitting component 42 and a receiving component 41, wherein the transmitting component 42 is disposed on the fixed plate 212, and the receiving component 41 is disposed on the movable plate 214. The positions of the transmitting component 42 and the receiving component 41 can be interchanged to improve the flexibility and convenience of assembly.

[0061] When the movable plate 214 and the fixed plate 212 clamp the ton bag, the induction signal emitted by the transmitting component 42 is blocked by the edge of the ton bag, and thus cannot be received by the receiving component 41. Therefore, when the receiving component 41 displays that the induction signal is received, it means that the ton bag is clamped in place. On the contrary, when the induction signal is still detected, it means that the ton bag is not clamped between the fixed plate 212 and the movable plate 214, that is, the ton bag is not clamped accurately.

[0062] In this embodiment, the receiving component 41 and the transmitting component 42 may be optical coupling transmitters and receivers, or infrared signal transceivers, etc.

[0063] Specifically, the launching assembly 42 includes a launching plate 421 and a launching end arranged on the launching plate 421, the fixing plate 212 is provided with a first clamping groove, the launching plate 421 has a raised first clamping portion, the first clamping portion is clamped in the first clamping groove so that the surface of the launching plate 421 is flush with the surface of the fixing plate 212.

[0064] In one embodiment, the installation position of the transmitting plate 421 is located at the rear end of the fixed plate 212, that is, the end that contacts the ton bag last. Therefore, when the receiving end does not receive the sensing signal, it can ensure that the fixed plate 212 and the movable plate 214 clamp the edge of the ton bag. Similarly, the receiving plate 411 and the receiving end are installed accordingly.

[0065] In another embodiment, the first clamping groove is provided on one end of the fixing plate 212 facing the first driving member 11 on the other side, and the launching plate 421 is installed at the front end of the fixing plate 212. By adjusting the groove depth of the first clamping groove, the surface of the fixing plate 212 and the surface of the launching plate 421 are made flush, and the ton bag is clamped as a whole. When no induction signal is received, it can be determined that the edge of the ton bag has been clamped.

[0066] The fixing plate 212 and the transmitting plate 421 can be detachably connected by screws, so as to facilitate the replacement and maintenance of the transmitting plate 421 and the transmitting end at a later time.

[0067] Similarly, the receiving plate 411 and the receiving end are installed correspondingly, the receiving component 41 includes a receiving plate 411 and a receiving end arranged on the receiving plate 411, the movable plate 214 is provided with a second snap-in groove, the receiving plate 411 has a raised second snap-in portion, the second snap-in portion is snapped in the second snap-in groove so that the surface of the receiving plate 411 is flush with the surface of the movable plate 214.

[0068] Furthermore, in order to improve the stability of grasping, two grasping assemblies 21 are installed on one driving assembly 10 .

[0069] The mounting plate 12 is mounted on the driving end of the first driving member 11. The mounting plate 12 is in a long strip shape, and its length direction is parallel to the extension direction of the guide rail 31. The two grabbing assemblies 21 are mounted on both sides of the mounting plate 12. Therefore, when grabbing, the front and back of the same side of the ton bag can be grabbed simultaneously by the two grabbing assemblies 21. Correspondingly, the two grabbing assemblies 21 on the other side cooperate with each other to realize the grabbing of the four sides of the ton bag at the same time, thereby improving the stability of the ton bag during the grabbing and transportation process.

[0070] The adjusting member 50 is disposed at the bottom or top of the guide rail 31 . The adjusting member 50 may be a screw rod module. The guide rail 31 is disposed on a screw rod nut seat, so that the height of the guide rail 31 can be adjusted by rotating the screw rod.

[0071] The height of the two guide rails 31 is adjusted to ensure that the heights of the two guide rails 31 are at the same horizontal position. A plurality of adjusting members 50 may be provided along the extending direction of the guide rails 31 to adjust the guide rails 31 to a horizontal position and prevent the guide rails 31 from tilting.

[0072] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
