Referring to fig. 1, fig. 1 is a schematic structural diagram of a process balance for automatically weighing coils according to an embodiment of the utility model. The utility model provides a process balance capable of automatically weighing coils. The controller 400 controls the movable lifting end 202 to drive the balance body 100 to move towards the coil 800 until the balance body 100 lifts the coil 800 to further lift a certain distance, so that the coil 800 is not contacted with the hook arm of the C-shaped hook 700. The scale body 100 weighs the coil 800. After the weighing is completed, the controller 400 controls the movable lifting end 202 to drive the scale body 100 to descend, and when the scale body 100 moves down to a set position, the downward movement is stopped, and the next weighing is waited. The coil 800 moves to the next process (moves in the arrow direction in the figure) under the driving of the C-shaped hook 700, and in the process, the end surface of the coil 800 facing the scale body 100 cannot scratch the scale body 100. The situation that the balance body 100 and the coil 800 are scratched due to the fact that the hooks are placed too early is solved. The accuracy of manual hook placement is improved, automatic weighing of the coil 800 is achieved, stable production of a production line is achieved, and production efficiency is improved.

Referring to fig. 1, in an embodiment of the present utility model, an automatic weighing coil process balance is provided, which includes a balance body 100, a jacking device 200, a first detector 300 and a controller 400. When the coil 800 is moved above the scale body 100 by the C-shaped hook 700, an operator stops the movement of the C-shaped hook 700 by a clamp (not shown in the drawing) and a stopper (not shown in the drawing) located above the C-shaped hook 700 and fixes it at the current position without shaking. The controller 400 controls the movable lifting end 202 to drive the balance body 100 to move towards the coil 800 until the balance body 100 lifts the coil 800 to further lift a certain distance, so that the coil 800 is not contacted with the hook arm of the C-shaped hook 700. The scale body 100 weighs the coil 800. After the weighing is completed, the controller 400 controls the movable lifting end 202 to drive the scale body 100 to descend, and when the scale body 100 moves down to a set position, a display signal is sent out, the movement is stopped, and the next weighing is waited. After the operator sees the display signal, the clamp is opened to put the hook, the coil 800 moves to the next procedure under the drive of the C-shaped hook 700, and in the process, the end face of the coil 800, facing the scale body 100, cannot scratch the scale body 100. The situation that the balance body 100 and the coil 800 are scratched due to the fact that the hooks are placed too early is solved. The accuracy of manual hook placement is improved, automatic weighing of the coil 800 is achieved, stable production of a production line is achieved, and production efficiency is improved.

It should be noted that, the coil 800 in this embodiment is circular and has a certain length in the axial direction, so that the scale body 100 can stably lift the coil 800 and separate the coil 800 from the hook arm of the C-shaped hook 700.

The scale body 100 is positioned relatively below the coil 800. When weights such as the coil 800 are sleeved on the hook arm of the C-shaped hook 700 and gradually move to the upper side of the balance body 100, the balance body 100 rises towards the direction of the coil 800 under the action of the jacking device 200 until the balance body 100 lifts the coil 800, so that the end face of the coil 800 is not contacted with the hook arm, and weighing of the coil 800 is started.

The jacking device 200 includes a base 201 and a movable lifting end 202, wherein the base 201 is relatively installed below the scale body 100, and the movable lifting end 202 extends toward the scale body 100. When the coil 800 needs to be weighed, the jacking device 200 is started, the balance body 100 can be jacked to the side, facing the balance body 100, of the coil 800, and the coil 800 is driven to move upwards continuously until the coil 800 is not contacted with the hook arm of the C-shaped hook 700 under the jacking of the balance body 100, and the balance body 100 weighs the coil 800. After the weighing is completed, the scale body 100 is driven by the jacking device 200 to descend to the set position, and the next coil 800 is waited for weighing. The jacking device 200 includes, but is not limited to, a hydraulic rod, a jacking cylinder, a jack, etc. having a lifting function driving member. In an embodiment of the present utility model, the jacking device 200 is a hydraulic cylinder. The hydraulic cylinder has good bearing capacity, is rapid and convenient to install, is applied to an enterprise environment, and can greatly improve the weighing efficiency of the coil 800.

The first detector 300 is installed on one side of the balance body 100 facing away from the coil 800, and when the first detector 300 detects that the balance body 100 descends to the set position, the first detector 300 sends an indication signal of "descending to the position", which indicates that when the coil 800 after weighing is completed goes forward, the end face of the coil facing the balance body 100 will not scratch the balance body 100 during the movement process. At this time, the operator can open the clamp to put the hook, the C-shaped hook 700 drives the current coil 800 to continue to move forward, and the other C-shaped hook 700 drives the next coil 800 to move above the scale body 100 to wait for weighing. Further, when the first detector 300 does not send an indication signal of "down in place", the C-shaped hook 700 does not move even if the operator puts the hook, thereby avoiding scratch of the coil 800 on the C-shaped hook 700 to the process balance due to misoperation of the operator.

The controller 400 is connected to the jacking device 200 and the first detector 300, respectively, and is used for associating the descent of the jacking device 200 with the first detector 300. Specifically, after the weighing is completed, in the process that the jacking device 200 drives the scale body 100 to descend, the first detector 300 determines whether the scale body 100 descends to the proper position by detecting the distance between the scale body 100 and the ground. If the balance is lowered into place, the movable lifting end 202 stops moving downwards, and the balance body 100 stops at the current position. Wherein, when the coil 800 moves away from the scale body 100 under the driving of the C-shaped hook 700, the coil 800 will not scratch the scale body 100.

Considering that when the balance body 100 moves up together with the coil 800, if the upward movement is too large, the coil 800 may scratch the hook arm of the C-shaped hook 700, resulting in damage to the hook arm or the coil 800, and affecting the engineering progress, in order to improve this problem, in an embodiment of the present utility model, a second detector 500 is installed on a side of the balance body 100 facing the coil 800, and the second detector 500 is in communication connection with the controller 400. When the coil 800 moves up to the set position, the second detector 500 sends out an alarm signal of "up-to-place", the controller 400 sends out control information, and the lifting end 202 is moved to stop moving up, so that the coil 800 cannot scratch the hook arm, and the efficiency of automatically weighing the coil 800 is improved.

To better achieve in-place detection of the scale body 100, in one embodiment of the present utility model, the first detector 300 and the second detector 500 are cold metal detectors. Preferably, in view of the multiple interference factors in the field environment, the detector is easy to fail, and in order to improve the detection accuracy, in one embodiment of the present utility model, the cold metal detector is an infrared light type cold metal detector. The infrared light type cold metal detector has excellent anti-interference capability and long detection distance, and can be applied to workshops such as high temperature workshops, humidity workshops and the like.

In an embodiment of the present utility model, the controller 400 is a plc controller 400, and a touch screen is disposed on the plc controller 400. The relevant parameters of the lifting or lowering of the scale body 100 can be set by the touch screen of the plc controller 400, and when the scale body 100 is lifted to the set position, the indicator lamp on the touch screen which is lifted in place is lightened, the lifting of the scale body 100 is stopped, and the coil 800 is weighed. When the weighing is completed and the balance body 100 is lowered to the set position, the indicator lamp of the touch screen, which is lowered to the set position, is lightened, and the balance body 100 stops lowering. Automatic weighing of the coil 800 is achieved.

In order to reduce friction between the balance body 100 and the coil 800 during weighing and to reduce wear of the balance body 100, in an embodiment of the present utility model, a protective film 101 is disposed on a side of the balance body 100 facing the coil 800. The protective film 101 can be adhered to the end face of the balance body 100 facing the coil 800, and once the protective film 101 is broken, another protective film 101 can be replaced in time, so that the balance body 100 is not damaged due to long-term friction with the coil 800.

In an embodiment of the present utility model, the scale body 100 is provided with an overweight alarm 600 (not shown in the drawings), and the overweight alarm 600 is connected to the controller 400. When the weight of the coil 800 exceeds the weighing limit of the scale body 100, the overweight alarm 600 sends out alarm information, and the alarm information is transmitted to the jacking device 200 through the controller 400, so that the lifting end 202 is moved to drive the scale body 100 to descend. The current coil 800 is no longer weighed. After the operator finds the alarm information, the other scale body 100 with the higher replaceable weighing limit continues to weigh. Thereby reducing the damage to the scale body 100 due to overload weighing, and thus the suspension of the weighing operation.

Considering that a certain impact force is generated on the scale body 100 when the movable lifting end 202 starts to lift, in order to alleviate the impact on the scale body 100, in an embodiment of the present utility model, a buffer 2021 is installed on the end surface of the movable lifting end 202 facing the scale body 100. The size of the buffer 2021 may be slightly larger than the size of the end surface of the movable lifting end 202, and the buffer 2021 may bear the lifting force from the movable lifting end 202 when the jacking device 200 is started. The buffer piece 2021 can avoid direct contact between the movable lifting end 202 and the scale body 100, so that the acting force of the movable lifting end can be buffered, and the service life of the scale body 100 can be effectively prolonged.

In one embodiment of the utility model, the buffer 2021 is an elastic rubber gasket. Because the elastic rubber gasket has certain elasticity, the impact force of the movable lifting end 202 on the scale body 100 can be buffered, the phenomenon that the scale body 100 shakes due to overlarge impact force between the movable lifting end 202 and the scale body 100 is avoided, and the overall stability of the process scale of the automatic weighing coil 800 is improved.

In conclusion, the utility model has simple structure. When the coil moves to the upper part of the balance body under the drive of the C-shaped hook, an operator stops the movement of the C-shaped hook through the clamp and the stopper which are positioned above the C-shaped hook and is fixed at the current position without shaking. The controller controls the movable lifting end top to drive the balance body to move towards the coil direction until the balance body lifts the coil to continuously ascend for a certain distance, and the coil is not contacted with the hook arm of the C-shaped hook. The balance body weighs the coil. After the weighing is completed, the controller controls the movable lifting end to drive the balance body to descend, and when the balance body moves down to a set position, a display signal is sent out, the movement is stopped, and the next weighing is waited. After the operator sees the display signal, the clamp is opened to put the hook, and the coil moves to the next procedure under the drive of the C-shaped hook, so that the end face of the coil, which faces the scale body, cannot be scratched to the scale body in the process. Solves the problem that the hook is too early to put, which leads to the situation that the scale body and the coil are scratched. The accuracy of manual hook placement is improved, automatic weighing of the coil is achieved, stable production of a production line is achieved, and production efficiency is improved. Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
