[0002] A zinc ingot workshop is responsible for putting the cathode zinc sheet after electrolysis into a zinc melting furnace for melting, then casting into zinc ingots through a straight-line ingot casting unit, and finally stacking the zinc ingots into an ordered zinc stack through a stacking device, and then carrying out post-processing such as bundling, metering and marking on the zinc stack for export.

[0003] In the process of putting the zinc sheet into the zinc melting furnace, a clamping fixture needs to be used to realize the transfer of the zinc sheet. In the prior art, a lifting type is used, that is, a lifting hanger is used to lift the zinc sheet stack on the feeding platform conveyor line, and then the zinc sheet stack is lowered into the feeding inlet of the zinc melting furnace. However, this method has the problems of long processing stroke and low efficiency, which seriously restricts the production speed of the enterprise. In addition, since the lifting method is to clamp and lower the horizontal zinc sheet, the zinc sheet cannot be vertically flipped, which causes the horizontal placement method to occupy a large space and is not conducive to the smooth arrangement into the zinc melting furnace.

[0024] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments of the application.

[0025] Referring to Figs. 1-3 The zinc sheet pile forming clamp feeding control system comprises a clamp unit, the clamp unit can move up and down and vertically overturn, and is used to clamp the zinc sheet pile and overturn the zinc sheet pile to the feeding inlet of the zinc melting furnace, that is, the clamp unit is used to move and overturn the zinc sheet pile feeding, and the feeding speed is effectively accelerated;

[0026] A control unit is used to control the up-down movement and overturning of the clamp unit, the up-down movement origin and the overturning origin of the clamp unit are detected by at least one detection switch, the at least one detection switch on each origin is electrically connected with the control unit, so that when the control unit detects the current action origin signal, the next action signal is outputted;

[0027] Further, the conveying unit is electrically connected with the control unit.

[0028] In some embodiments, an upper limit switch is further arranged on the up-and-down moving track of the clamp unit, and after the clamp unit clamps the zinc sheet stack at the upper original point, the clamp unit is lifted to the upper limit switch to start vertical downward turning, while the push assembly drives the sprocket chain assembly to move backward to reset, and after the clamp unit turns down, the clamp unit is lowered to the lower original point to release the clamping, and after the zinc sheet stack is sent into the zinc melting furnace, the clamp unit is lifted to the upper limit switch to turn to reset, and then is lowered to the upper original point to wait for clamping.

[0029] In summary, the specific control process of the control system in the present application is as follows:

[0030] In the automatic mode: the zinc sheet first reaches the sprocket chain, and in this state, the feeding shoe has a material signal, the control unit drives the push assembly to move, so that the push assembly pushes the sprocket chain assembly to reach the pre-feeding position, and in this state, the push assembly pushes the in-place signal, and the feeding shoe has a material signal.

[0031] At this time, the clamp is clamped, and the clamp clamping time can be adjusted according to the height of the zinc sheet, the clamp is lifted to the high position, the upper limit switch has a signal, the sprocket chain assembly is reset to the original position, and the push assembly triggers the original position signal.

[0032] Further, the clamp assembly turns down until the clamp down signal is triggered, the control unit controls the clamp assembly to lower to the low position until the clamp arm of the clamp assembly is released after the lower original point signal is triggered, and until the clamp release in-place signal is triggered.

[0033] Further, the clamp assembly is lifted to the high position until the upper limit switch is triggered, the clamp assembly is turned up to the position until the clamp assembly turning up original point signal is triggered, and then the clamp is lowered to the middle position until the upper moving original point signal is triggered.

[0034] In addition, in other embodiments, mechanical limit preventing switches can be installed at some key positions in the present application to prevent the failure of the switches, such as mechanical structures such as anti-collision columns.

[0035] In addition, the pressure sensor is arranged in the clamp unit, and is used for detecting the clamping force of the clamp unit on the zinc sheet stack, so as to determine whether the clamp unit is clamped successfully, and the pressure sensor is electrically connected with the control unit, that is, the clamping force on the zinc sheet stack can be controlled by the control unit, and the next action is performed when the clamping force reaches a threshold value, so that the zinc sheet stack with different weights can be stably clamped.

[0036] On the basis of the above embodiment, the detection switch for detecting the opening point of the at least two clamping arms is arranged in the clamp unit, so that when the clamp unit releases the zinc sheet stack, the at least two clamping arms are opened to the opening point, and the zinc sheet stack is released, the detection switch is electrically connected with the control unit, and as described above, when the two clamping arms are opened to the opening point, the control unit receives the position signal, and at this time, the clamp assembly can be lifted to the high position, so as to complete the feeding.

[0037] More specifically, the control unit comprises a CPU module, a touch screen, a digital input and output module, an analog input and output module, a communication module and an electric control element module.

[0038] The touch screen is used for displaying the running state of the equipment, the triggering state of each switch, the manual / automatic mode switching, the start / stop of the automatic mode and the manual operation interface.

[0039] In the manual operation mode, the normal manual state is the jog state, all the hydraulic components are jogged, the equipment can be run in the empty load linkage mode for trial, and when the equipment is run in the empty load mode, the running state of each part is detected, and the position and reliability of the photoelectric switch and the travel switch of each point of the equipment are comprehensively detected in cooperation with the original position display.

[0041] Further, the electric control element comprises a circuit breaker, a fuse, an alternating current contactor, a thermal relay, a frequency converter, a switching power supply, a switch and an intermediate relay, the frequency converter is used for adjusting the driving speed of each hydraulic component, so that the feeding speed and frequency of the whole system are adjustable, the action is stable and orderly, and the requirements of the production rhythm of the workshop are met.

[0042] Specifically, the detection switch is one of a proximity switch, a photoelectric switch, a magnetic switch or a travel switch, each detection switch signal line is connected to the junction box, and then is connected to the control unit.

[0043] In addition, the application also comprises an in-situ detection module for detecting the initial position of the current clamp unit and conveying unit. If the initial position is not detected, the system cannot enter the automatic mode and needs to be aligned in the manual mode first.

[0044] That is, the control system of the application needs to detect the initial position of each unit before operating in the automatic mode. An indicator light can also be added. If the in-situ state indicator light is not on, it indicates that there is a problem with the in-situ state. Clicking the in-situ signal query button can query the in-situ state. If the points are not in the in-situ state, switch to manual operation. If all points are in the in-situ state, proceed to the next step. Since the adjustment of the in-situ state is performed in the manual operation page, the in-situ state is also displayed in the manual operation page, which can also be queried.

[0045] Specifically, the application also comprises a hydraulic control box. The up and down movement and the overturning of the clamp unit are controlled by hydraulic components. The push assembly is also a hydraulic component. The hydraulic control box is connected to the control unit and is connected to each hydraulic component in turn.
