Technical Field

[0001] The utility model relates to the technical field of strip steel production, in particular to a mechanical induction fence for controlling the automatic flipping of a strip steel automatic flipper. Background Art

[0002] When strip steel is produced, it is usually placed flat in a warehouse, and to fix the strip steel on a keel machine, the strip steel needs to be flipped to an upright position by a flipper.

[0003] Currently, the flipping of the strip steel is usually controlled by an operator. First, the strip steel is placed on the flipper by a forklift. After the forklift forks leave the flipper, the operator controls the flipper to flip. After the flipping is completed, the strip steel is removed by the forklift, and then the operator controls the flipper to reset. Although the prior art can complete the flipping task of the strip steel, the flipping process requires the operator to cooperate with the forklift to control the flipping or resetting of the flipper after the forklift forks leave the flipper. The automation degree in this process is low, increasing the workload of the operator and resulting in low work efficiency.

[0004] Therefore, the prior art has problems of low automation degree, wasting the energy of the operator, and thus resulting in low work efficiency. Summary of the Utility Model

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] As Figure 1 shown, the present invention provides a mechanical induction fence for controlling the automatic flipping of the strip steel automatic flipper, including:

[0031] Base 1, which is arranged around the flipper to enclose it;

[0032] Two safety fences 2, symmetrically arranged on the base 1, the safety fence 2 has an upper fence 21 and a lower fence 22, and the upper fence 21 is movably installed on the lower fence 22;

[0033] Two sets of elastic support members 3 are respectively arranged on two safety fences 2. The elastic support member 3 includes a spring telescopic rod 31 and a pressure sensing component 32. The spring telescopic rods 31 are respectively connected to the lower fence 22 and the upper fence 21, and the pressure sensing component 32 is used to detect the pressure signal of the spring telescopic rod 31;

[0034] A controller 4 is arranged on the base 1 and connected to the motor of the turnover machine to confirm the state of the upper fence 21 according to the pressure signal fed back by the pressure sensing component 32 and control the turnover of the turnover machine;

[0035] When the forklift presses down the upper fence 21 to enter the turnover machine to place and take the strip steel and then leaves, after the pressure sensing component 32 senses that the pressure signal first increases and then decreases to the initial value, the controller 4 determines that the forklift is far away and controls the turnover machine to turnover.

[0036] In this embodiment, mainly when the forklift places the strip steel, it presses down the upper fence 21, so that the spring telescopic rod 31 is pressed down and triggers the pressure sensing component 32. The pressure sensing component 32 feeds back the pressure signal to the controller 4. After the forklift completely leaves, the upper fence 21 resets with the spring telescopic rod 31. At the same time, the pressure sensing component 32 detects the pressure change and feeds back the signal to the controller. When the pressure sensing component 32 senses that the pressure signal changes from increasing to decreasing to the initial value, the controller 4 determines that the forklift is far away and controls the turnover machine to turnover 90 degrees in the opposite direction to the direction where the forklift places the strip steel. Similarly, during the process of the forklift picking up the strip steel and leaving, the pressure sensing component 32 detects the pressure change and outputs a signal, and the controller 4 controls the turnover machine to turnover 90 degrees in the opposite direction to the direction where the forklift picks up the strip steel to reset.

[0037] Compared with the existing method of manually controlling the turnover of the strip steel by the turnover machine, in this embodiment, when placing and picking up the strip steel with a flat fork, it can press down the upper fence 21 in the corresponding direction, trigger the pressure sensing component 32 at that place and output a pressure signal. After the flat fork leaves, the upper fence 21 in that direction resets with the spring telescopic rod 31. At the same time, the pressure sensing component 32 outputs a pressure change signal. When the pressure sensing component 32 senses that the pressure increases from increasing to decreasing to the initial value, the controller 4 determines that the forklift is far away and controls the turnover machine to turnover 90 degrees in the opposite direction to the direction where the forklift enters to turnover or reset, realizing the automatic control of the strip steel turnover, reducing the work intensity of the operator and improving the work efficiency.

[0038] Among them, in this embodiment, the safety fence 2 can be directly installed around the existing turnover machine, and the controller 4 is connected to the motor of the existing turnover machine to control its turnover, which can directly improve the existing turnover machine that cannot be automatically turned over.

[0039] In this embodiment, the elastic telescopic rod 31 can be pressed down with the entry of the forklift fork and rebound and reset when the forklift fork leaves. Therefore, the following preferred embodiment is proposed.

[0040] Such asFigure 2 As shown, the spring telescopic rod 31 includes a sleeve 311 and a fixed rod 312. The sleeve 311 is sleeved above the fixed rod 312. A spring 313 is arranged at the lower end of the sleeve 311, and the spring 313 is sleeved on the fixed rod 312.

[0041] Specifically, when the forklift fork enters, the sleeve 311 presses down the spring 313 and is sleeved on the fixed rod 312. After the forklift fork leaves, the sleeve 311 can rebound and reset under the action of the spring 313.

[0042] The pressure sensing component 32 needs to detect a pressure signal when the forklift fork enters and sense a pressure change signal when the forklift fork completely leaves, so as to determine that the forklift has moved away from the tilter. Therefore, the following preferred embodiments are proposed.

[0043] As Figures 1 to 3 shown, the upper side of the upper end of the fixed rod 312 has a groove 314. The pressure sensing component 32 is arranged in the groove 314, and its measuring end extends outside the groove 314 to detect a pressure signal after the sleeve 311 moves down.

[0044] The pressure sensing component 32 includes a pressure sensor 321, a return spring 322 and a trigger block 323. The pressure sensor 321 is arranged at the bottom end of the groove 314. One end of the return spring 322 is arranged in the groove 314 and fixed on the pressure sensor 321. The other end of the return spring 322 is fixedly connected to the trigger block 323, and the trigger block 323 is partially exposed outside the groove 314.

[0045] Specifically, when the forklift fork places the strip steel, the sleeve 311 is pressed down accordingly, and at the same time, the trigger block 323 extending out of the upper side of the upper end of the fixed rod 312 is pressed into the groove 314 to trigger the pressure sensor 321 at the bottom of the groove 314. The pressure sensor 321 senses the pressure and feeds back a signal. When the forklift fork completely leaves, the sleeve 311 rebounds and resets under the action of the spring 313. When the sleeve 311 rebounds to the upper limit position, the return spring 322 pops out the trigger block 323. At the same time, the pressure sensor 321 senses a pressure change signal, and the pressure sensor 321 feeds back the pressure change signal to the controller 4 and determines that the forklift has left.

[0046] When the forklift fork places and takes the strip steel, it directly presses down the upper fence 21, thereby pressing down the sleeve 311, and the upper fence 21 can reset with the sleeve 311 when the forklift fork leaves. Therefore, the following preferred embodiments are proposed.

[0047] As Figure 1 and 2 shown, the sleeve 311 is fixed on the upper fence 21, and the fixed rod 312 is fixed on the lower fence 22 or the base 1.

[0048] Specifically, the sleeve 311 is fixed to the upper fence 21 so that the sleeve 311 can be pressed down with the upper fence 21, and when the forklift leaves, the upper fence 21 can also be reset with the sleeve 311.

[0049] Among them, the fixing rod 312 is fixed to the lower fence 22 or the base 1, and the lower fence 22 should be offset from the upper fence 21 to ensure that the upper fence 21 can be pressed down smoothly.

[0050] After the upper fence 21 is pressed down, it should be ensured that the forklift can completely place the strip steel on the placement surface of the turnover machine. At the same time, it should be ensured that the forklift can only be pressed down from above the upper fence and will not be inserted from the middle of the upper fence 21. Therefore, the following preferred embodiments are proposed.

[0051] As Figure 1 shown, the height of the lower fence 22 and the height after the upper fence 21 is pressed down are both less than or equal to half of the turnover machine body;

[0052] Both the upper fence 21 and the lower fence 22 are provided with a net 23, and the bottom of the lower fence 22 is left empty.

[0053] Specifically, the height of the lower fence 22 and the height after the upper fence 21 is completely pressed down are both less than half of the turnover machine body, which can ensure that the forklift can be completely pressed down to the placement surface of the turnover machine, and the nets 23 provided on the upper fence 21 and the lower fence 22 can isolate the turnover machine, and only by pressing down the upper fence 21 can one enter.

[0054] Among them, the risk-free area at the bottom of the lower fence 22 can be left empty without setting the net 23 to save raw materials.

[0055] According to the above embodiments, when the forklift places the strip steel, when entering, the upper fence 21 on that side is pressed down, the sleeve 311 is simultaneously pressed down and the trigger block 323 is pressed into the groove 314, triggering the pressure sensor 321 and feeding back a pressure signal. After the forklift has finished placing and completely left, the upper fence 21 rebounds with the sleeve 311 to be completely reset. At the same time, the return spring 322 pops out the trigger block 323, and the pressure sensor 321 outputs a pressure change signal. When the pressure sensor 32 senses that the pressure signal increases and then decreases to the initial value, the controller 4 controls the turnover machine to flip 90 degrees in the opposite direction of the forklift placement to flip the strip steel; similarly, when the forklift forks the strip steel, when entering, it presses down the upper fence 21 and triggers the pressure sensor 321 to output a pressure signal. When leaving, the upper fence 21 rebounds and resets with the sleeve 311, the pressure sensor 321 senses the pressure change signal and feeds it back to the controller 4, and the controller 4 controls the turnover machine to flip 90 degrees in the opposite direction of the forklift forking to reset.

[0056] It should be noted that the upper fence 21 is supported by a plurality of spring telescopic rods 31, that is, it is equipped with a plurality of pressure sensing components 32, and the plurality of pressure sensing components 32 are redundant to each other, so that the function of automatic flipping can still be realized when one of them is damaged.

[0057] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
