Abstract
The utility model relates to a horizontally rolled clamp jam-prevention device. Two symmetrical inward bending clamp legs of a horizontally rolled clamp are opposite at an interval. The horizontally rolled clamp jam-prevention device is characterized in that the inner side of each clamp leg is respectively provided with a limit photoelectric inductor; the clamp is provided with a PLC (programmable logic controller) control box, and is internally provided with a lead control chain; and each lead is connected to each input point in the PLC control box. The horizontally rolled clamp jam-prevention device is simple in structure, is convenient to control, and can eradicate or slow down the situation of steel reel jamming.
Description
Technical field
The utility model relates to the horizontal coil clamp safety guard, is specifically related to a kind of horizontal coil clamp preventing damage device.
Background technology
At present, most horizontal coil clamp control panels connects gear by electrical motor by chain-driving and rotates at the driving electric panel room, makes clamp two pincers legs clamp or unclamp.Electrical motor is controlled by two contactless switchs, and the release that clamps contactless switch relies on overcurrent relay to control, and clamps or the degree of unclamping is that normal width according to coil of strip is to move by over current relay and protect parking in the basis.When only having the clamp motor to reach the 5A electric current in practical work process, the pincers leg just can stop clamping, so easily cause crimping and breakage to going out the serious and thinner coil of strip in limit, not only affecting the coil of strip presentation quality but also will again shearing bundling has increased productive costs.
Summary of the invention
The technical problems to be solved in the utility model is: solve existing clamp and pass through overcurrent protection; the coil of strip mass defect of bringing in the time of just stopping clamping when only reaching the electric current of setting; a kind of horizontal coil clamp preventing damage device is provided, can stops or slow down the situation that crushes coil of strip to occur.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Horizontal coil clamp preventing damage device, two curved pincers leg in symmetrical left and right relative spacings of horizontal coil clamp; It is characterized in that respectively clamping inboard leg one limit photoelectric sensor all is set; The PLC control box is set, the inner pilot chain of installing of clamp, each entrance point in each wire access PLC control box on clamp.
By technique scheme, distance pincers inboard leg wall place respectively clamps perforate on leg guard, and a limit photoelectric sensor is set in each hole, and the detection side of left and right limit photoelectric sensor is to parallel.
By technique scheme, each limit photoelectric sensor all accesses in the PLC control box by wire.
By technique scheme, the PLC control box is connected with the clamp actuating device by 19 core cable spare wires.
With respect to prior art, the utlity model has following beneficial effect:
At distance pincers inboard leg, the optoelectronic induction limit is arranged on clamp backplate bottom, control with the entrance point of the both sides optoelectronic induction limit and clamp output, guarantee that both sides pincers leg stops action near coil of strip 10mm the time, prevent the coil of strip collision.Simple in structure, be convenient to control.
The PLC control box is installed on clamp, the inner pilot chain of installing of clamp, when preventing from clamping the leg motion, wire is broken.Then wire is accessed Siemens 200PLC entrance point.Enable former driving 19 core cable spare wires and control the clamping of opening of clamp.Transformation is simple, and saves cost.
Description of drawings
Fig. 1 is horizontal coil clamp preventing damage apparatus structure schematic diagram of the present utility model;
Fig. 2 is PLC control inputs point arrangement plan of the present utility model.
In figure, the Reference numeral correspondence is as follows: horizontal coil clamp 1, pincers leg 2, limit photoelectric sensor 3, PLC control box 4, clamping switch entrance point I2.0, left-limit photoelectric sensor entrance point I2.1, limit on the right-right-hand limit photoelectric sensor entrance point I2.2, overcurrent protection entrance point I2.3, open contactless switch entrance point Q3.1, clamp contactless switch entrance point Q3.2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, horizontal coil clamp preventing damage device of the present utility model, two symmetrical interior curved pincers leg 2 left and right relative spacings of horizontal coil clamp 1, distance pincers inboard leg 5mm place respectively clamps perforate on leg guard (aperture 16mm), a limit photoelectric sensor 3 is set in each hole, and the detection distance of left and right limit photoelectric sensor 3 all is made as maximum 2 meters; Prevent the coil of strip collision.
PLC control box 4 is installed on clamp 1, the inner pilot chain (not shown) of installing of clamp 1, when preventing from clamping leg 2 motion, wire is broken.Then wire is accessed each entrance point in PLC control box 4.PLC control box 4 is connected with the clamp actuating device by 19 core cable spare wires, enables the clamping of opening that former driving 19 core cable spare wires are controlled clamp.
The present embodiment is Siemens 200PLC entrance point; concrete control inputs point is arranged as shown in Figure 2, clamping switch entrance point I2.0, left-limit photoelectric sensor entrance point I2.1, overcurrent protection I2.3 is set respectively, opens contactless switch Q3.1, clamps contactless switch Q3.2 according to timing node.The parallel effect simultaneously of limit on the right-right-hand limit photoelectric sensor entrance point I2.2 and left-limit photoelectric sensor entrance point I2.1.During real work, detect 2 meters beginnings of distance from maximum, left-limit photoelectric sensor entrance point I2.1 and limit on the right-right-hand limit photoelectric sensor entrance point I2.2 control and clamp output, guarantee that both sides pincers leg 2 stops entrance point near coil of strip 10mm the time.
