Description

Technical Field

[0001] The utility model relates to the technical field of ton bag hanging, in particular to a ton bag hanging device. Background Art

[0002] Most of the existing ton bag hanging methods are done manually, with workers installing the ton bag's hanging ears on the equipment, and then using the equipment to perform subsequent related work. This is not only inefficient, but the dust that overflows when being hung will also endanger the workers' health.

[0003] At present, there are also ways to use equipment to achieve automatic hanging of ton bags. The automatic hooking method usually hooks into the ton bag through the claws, and then lifts the ton bag materials. This method has the following problems: after the ton bag is packed with materials, the positions and shapes of the four hanging ears of the ton bag are random and irregular, and because the ton bag itself is made of flexible material, during the process of grabbing and lifting the ton bag, the claws can easily hook directly into the inside of the ton bag, which will not only damage the ton bag, but also contact the materials in the ton bag, thereby increasing the risk of foreign matter and contaminated materials. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing ton bag hanging devices, the applicant provides a ton bag hanging device with a reasonable structure to reduce the risks of ton bag damage and material contamination.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A ton bag hanging device, a support frame is provided with a plurality of hanging arms, the hanging arms are provided with hooks, the hooks are driven by a driving mechanism to move toward or away from the ton bag; when hanging the bag, the hooks are first squeezed onto the part of the ton bag located below the hanging ears, and the bag is hung after the hanging ears are exposed.

[0007] As a further improvement of the above technical solution:

[0008] The boom is movably connected to the support frame, the hook is fixed on the boom, the driving mechanism is connected to the boom, and the driving mechanism drives the hook through the boom.

[0009] The boom is hinged to the support frame through a pin shaft, and the driving mechanism can drive the boom to swing; or, the boom is connected to the support frame through a sliding matching structure, and the driving mechanism can drive the boom to move horizontally.

[0010] The boom is fixed on the support frame, the driving mechanism is arranged on the boom, the driving mechanism is connected with the hook, and the driving mechanism directly drives the hook to rotate or translate.

[0011] A locking mechanism is arranged on the boom, and the locking mechanism cooperates with the hook to lock the hanging ear.

[0012] The locking mechanism includes a support plate, a driving member and a latch. The support plate is fixed on the boom, the driving member is fixed on the support plate, the latch is inserted into the support plate and connected to the driving member; a socket is provided on the hook corresponding to the latch of the locking mechanism, and the latch cooperates with the socket to achieve locking or loosening.

[0013] The locking mechanism is arranged above or on one side of the hook.

[0014] An image sensor is arranged on the suspension arm, a first photoelectric sensor is arranged on the hook, and a second photoelectric sensor is arranged on the locking mechanism.

[0015] The hook is a horizontal hook, and the insertion hole is vertically opened on the crossbar of the hook. The upper surface of the outer side of the hook facing the ton bag is an inclined surface, which is higher inside and lower outside. The edges of the outer end of the hook are transitioned through larger fillets; or the hook is a U-shaped hook.

[0016] The drive mechanism can automatically adjust the movement of the boom or hook.

[0026] The specific implementation of the utility model is described below in conjunction with the accompanying drawings.

[0027] First embodiment:

[0028] like Figure 1 As shown, the bag hanging device 200 of the utility model comprises a support frame 1, a plurality of suspension arms 2, and a hook 3 arranged at the bottom end of the suspension arm 2. The ton bag 100 for bag hanging by the utility model is a double-layer structure, including an outer bag 101 and an inner bag 102, and a hanging ear 103 is connected to the outer bag 101.

[0029] like Figure 1 , Figure 2 As shown, in this embodiment, a plurality of booms 2 are rotatably arranged on a support frame 1. The top ends of the plurality of booms 2 are hinged to the support frame 1 through a pin shaft, and a hook 3 is fixed to the bottom end of the boom 2 and protrudes on the side of the boom 2 facing the ton bag 100. The boom 2 is connected to a driving mechanism 4, which can drive the boom 2 to swing around the pin shaft, thereby driving the hook 3 to move toward or away from the ton bag 100. The driving mechanism 4 is arranged on the support frame 1, and the driving mechanism 4 can be a cylinder, an oil cylinder, an electric cylinder, or other driving components that can drive the boom 2 to rotate.

[0030] A locking mechanism 5 is provided on the boom 2 above the hook 3. After the hook 3 hooks the lug 103 of the ton bag 100, the locking mechanism 5 cooperates with the hook 3 to lock the lug 103 to prevent the lug 103 from falling off the hook 3, thereby causing the ton bag 100 to fall. The locking mechanism 5 includes a support plate 51, a driving member 52 and a latch 53. The support plate 51 is fixed on the boom 2, the driving member 52 is fixed on the support plate 51, the latch 53 is inserted on the support plate 51 and connected to the driving member 52, and the driving member 52 can drive the latch 53 to move up and down. A plug hole 31 is provided on the hook 3 corresponding to the latch 53 of the locking mechanism 5. When locking, the latch 53 of the locking mechanism 5 is driven by the driving member 52 to move downward and insert into the plug hole 31. When releasing, the latch 53 is driven by the driving member 52 to move upward and withdraw from the plug hole 31.

[0031] An image sensor 6 is also provided on the boom 2. The image sensor 6 is located above the hook 3 and the locking mechanism 5. The image sensor 6 can monitor the position of the hook 3 in real time and determine whether the position of the hook 3 is within the area where the bag can be hung.

[0032] The hook 3 is provided with a first photoelectric sensor 7, which can monitor the lug 103 to determine whether the lug 103 is hung in the hook 3. The locking mechanism 5 is also provided with a second photoelectric sensor 8, which can determine whether the locking mechanism 5 is locked in place.

[0033] The hook 3 of this example is a horizontal hook, and the insertion hole 31 is vertically opened on the crossbar of the hook 3. The upper surface of the outer side of the hook 3 facing the ton bag 100 is a slope 32, and the slope 32 is high inside and low outside, which is convenient for the hook 3 to be quickly and smoothly hooked onto the hanging ear 103 of the ton bag 100, thereby improving the bag hanging efficiency. The edges of the outer end of the hook 3 are transitioned through a large fillet 33, so that the end becomes a smooth round head, avoiding the existence of sharp edges and scratching the bag body of the ton bag 100.

[0034] The driving mechanism 4 can adjust the swing amount of the boom 2 according to the situation monitored by the image sensor 6, thereby adjusting the swing amount of the hook 3 so that the hook 3 is hooked in, thereby realizing automatic position correction.

[0035] When the bag hanging starts in this embodiment, the bag hanging device 200 moves first to reduce the relative distance between it and the ton bag 100, until the hook 3 reaches directly below the hanging ear 103 of the ton bag 100, and then the driving mechanism 4 drives the boom 2 to swing toward the ton bag 100, and the hook 3 is squeezed onto the portion of the ton bag 100 below the hanging ear 103, so that the outer bag 101 and the inner bag 102 at this portion of the ton bag 100 are separated, so that the hanging ear 103 is exposed from the ton bag 100, and after the image sensor 6 determines that the hook 3 reaches the area where the bag hanging can be completed, the ton bag 100 and the bag hanging device 200 produce relative displacement, and the first photoelectric sensor 7 determines that the hanging ear 103 is in the hook 3, and then the locking mechanism 5 drives the pin 53 to insert into the socket 31 of the hook 3 and lock it, completing the bag hanging work.

[0036] Second embodiment:

[0037] like Figure 3 As shown, the difference between this embodiment and the first embodiment is that the arm 2 of this embodiment is slidably arranged on the support frame 1, and the arm 2 is connected to the support frame 1 through a sliding matching structure, such as a slider matching a slide rail. The driving mechanism 4 is connected to the arm 2, and can drive the arm 2 to slide horizontally, thereby driving the hook 3 to move toward or away from the ton bag 100. When hanging the bag, the driving mechanism 4 drives the arm 2 to move horizontally toward the ton bag 100, so that the hook 3 is pressed tightly against the part of the ton bag 100 located below the hanging ear 103. After the image sensor 6 determines that the hook 3 has reached the area where the bag can be hung, the ton bag 100 and the bag hanging device 200 produce relative displacement, and the first photoelectric sensor 7 determines that the hanging ear 103 is in the hook 3, and then the locking mechanism 5 drives the pin 53 to insert into the socket 31 of the hook 3 and lock it, completing the bag hanging work.

[0038] The driving mechanism 4 can adjust the translation amount of the boom 2 according to the situation monitored by the image sensor 6, thereby adjusting the translation amount of the hook 3 so that the hook 3 can be hooked in to achieve automatic position correction.

[0039] Third embodiment:

[0040] like Figure 4 , Figure 5 As shown, the difference between this embodiment and the first embodiment is that the arm 2 of this embodiment is fixedly connected to the support frame 1, the driving mechanism 4 is arranged on the arm 2, and the hook 3 is directly connected to the driving mechanism 4 and driven by the driving mechanism 4. In this embodiment, the driving mechanism 4 is a rotating structure, the hook 3 is a U-shaped hook, and the locking mechanism 5 is arranged on one side of the hook body of the hook 3. When hanging bags, after the image sensor 6 determines that the hook 3 has reached the area where the bag hanging can be completed, the driving mechanism 4 drives the hook 3 to rotate and hook into the hanging ear 103, and then the locking mechanism 5 drives the pin 53 to insert into the socket 31 of the hook 3 and lock it to complete the bag hanging work. In other embodiments, the driving mechanism 4 can also be a horizontal mechanism, the hook 3 adopts a horizontal hook, and the driving mechanism 4 drives the hook 3 to move horizontally to achieve bag hanging. In this case, the driving mechanism 4 can adjust the movement of the hook 3 according to the situation monitored by the image sensor 6 to achieve automatic deviation correction.

[0041] When hanging bags, the utility model drives the hook 3 by the driving mechanism 4 to first squeeze the portion of the ton bag 100 below the hanging ear 103, so that the outer bag 101 and the inner bag 102 of the ton bag 100 are separated, and after the hanging ear 103 is exposed from the ton bag 100, the bag is hung by the hook 3, so that the hook 3 can quickly and accurately hook the hanging ear 103, thereby improving the efficiency of hanging bags and reducing the risk of the hook 3 hooking into the inside of the ton bag 100 and damaging the ton bag 100 and polluting materials; and the hook 3 hooks into the hanging ear 103 from bottom to top, so the success rate of hanging bags is higher.

[0042] The above description is an explanation of the utility model, not a limitation of the utility model. The utility model can be modified in any form without violating the spirit of the utility model.
