Embodiment
Below, in conjunction with the accompanying drawings specific embodiment of the utility model is described.
Fig. 1 is the circuit diagram that sealing-tape machine of the present utility model suddenly stops to protect control device on the spot; Fig. 2 is the electrical block diagram that sealing-tape machine of the present utility model suddenly stops to protect the manual control unit of control device on the spot.
As depicted in figs. 1 and 2, sealing-tape machine of the present utility model suddenly stops to protect control device to have manual control unit on the spot;
Described manual control unit comprises: have first relay K, 7, the second relay K 2 of a plurality of normally closed points and a plurality of normal battles, and the coil of the vacuum contactor KM that connects with the motor that drives sealing-tape machine;
One group of normally closed point of described first relay K 7 is connected with the coil of described second relay K 2, and another of described first relay K 7 organized normally closed point and connected with the normal battle of described second relay K 2, and connect with the coil of described vacuum contactor KM the normal battle of described second relay K 2.
Described sealing-tape machine suddenly stops to protect in the control device on the spot, and the coil of described first relay K 7 is connected with the stay cord protection switch, and the coil of described first relay K 7 is connected with the sideslip protection switch.
And described sealing-tape machine suddenly stops to protect control device also to have the 3rd relay K 5 of cutting off described first relay K 7 in order to control on the spot.
And, described sealing-tape machine suddenly stop to protect control device also to comprise control on the spot another drives the 4th relay K 8 of sealing-tape machine motor, often make war for one group of described the 4th relay K 8 and described first relay K 7 to connect.
Described first relay K 7, second relay K 2, the 3rd relay K 5, the 4th relay K 8 are auxiliary relay.
Particularly; for example at first get the power supply of a 220V from control cubicle; with for example head; middle part and afterbody stay cord or " normally closed " above sideslip relay protection switch passive node are together in parallel; need increase an auxiliary relay K7 at the drive motors control cubicle then; PLC control cubicle relay passive node is inserted on the auxiliary relay K7 coil of drive motors control cubicle increase; select one group of normally closed point control of auxiliary relay K7 to be used for the coil of auxiliary relay K2 of coil power of controlling and driving motor vacuum contactor KM then, another that select auxiliary relay K7 organized often the make war power supply of series connection control vacuum contactor coil of normally closed point and auxiliary relay K2.
Like this, when stay cord relay protection switch is pulled by the staff and when moving, perhaps during rubber belt from deviating, the controlled disconnection of auxiliary relay K7, thereby the vacuum contactor KM that control is connected with sealing-tape machine motor disconnection are in time shut down the sealing-tape machine motor.
In addition, even adhesion phenomenon appears in auxiliary relay K7 contact, auxiliary relay K7 can also control auxiliary relay K2 and disconnect, and also can disconnect vacuum contactor KM effectively and realizes shutting down.Thus, sealing-tape machine of the present utility model suddenly stops to protect control device can realize duplicate protection (if be multi-drive motor, can get the auxiliary relay coil that one group of other drive motors control cubicle of control of often making war increases so from middle relay K 7) on the spot.
In addition, sealing-tape machine of the present utility model suddenly stops to protect control device meanwhile also can realize concentrating control automatically on the spot.Under collection control condition, can cut off auxiliary relay K7 by auxiliary relay K5, the influence of system when cancelling with this that condition increases circuit to the collection control on the spot.
Sealing-tape machine of the present utility model suddenly stops to protect control device to realize sealing-tape machine " stay cord " and " sideslip " protection timely under " on the spot " state of a control on the spot; Increase duplicate protection, solved the problem that the auxiliary relay adhesion causes vacuum contactor to trip; Realized quick response, the reliable demand of protective value, and simple in structure and cost is low.
Technical scope of the present utility model not only is confined to the content in the above-mentioned explanation, those skilled in the art can be under the prerequisite that does not break away from the utility model technological thought, the foregoing description is carried out various deformation and modification, and these distortion and revise to work as and belong in the scope of the present utility model.
