A control device for a winding machine relates to a winding machine used during the operation of a prestressed concrete pipe. The winding machine comprises a controller, a concrete pipe rotation driving device, a line arranging device, a line arranging device running guide rail, a force measuring device, and a stress device producing set tension to wires, wherein, the concrete pipe rotation driving device, the line arranging device, the force measuring device and the stress device are connected with the controller; the line arranging device comprises a guide wire trolley and a diving motor diving the guide wire trolley to conduct a reciprocating movement at a fixed speed relative to the concrete pipe; the concrete pipe rotation driving device drives the concrete pipe to run at a set rotating speed, so as to ensure that the wires are wound on the concrete pipe at a set thread pitch; a regulating circuit which commands the stress device to change the stress and ensures the basically consistent stress which is applied on the wires by the guide wire trolley during the return and feeding process is arranged in the controller. Due to bi-directional winding, the utility model has the advantages that the idle stroke time is saved and the work efficiency is improved.

Description

Twine the control device of a machine

Technical field

The utility model relates to a kind of machine that twines of using when producing prestressed concrete pipe, and relates in particular in feeding, the two-way equal horizontal or vertical control system that twines a machine that can twine silk of return.

Background technology

In order to make the prestressed concrete pipe of producing (three stages, PCCP) can bear certain external pressure and interior pressure, need twine compressor wire by certain distance at the pipe of concrete outer core.Prior art lacks the feedback to the device for measuring force measurement data, owing to there is not digital governer, the data of measurement can only be used for record, therefore, lacks the adjusting of counter stress fluctuation, causes stress fluctuation bigger.Existingly twine a machine owing to not do not regulate the device of given pulling force according to the winding displacement direction, can only be to a direction winding steel wire, after the end again idle stroke reset and continue an operation that twines of root pipeline down.Therefore exist operating efficiency not high, in process of production long shortcoming of the time of Deng Daiing.

The utility model content

The utility model provides a kind of and not only can twine silk when feeding at deficiency of the prior art, can also twine the control device that twines a machine of silk when return.

The technical solution of the utility model is: comprise controller, pipe of cement device for revolving and driving, bus cable device, bus cable device operation guide rail, device for measuring force, silk is produced a power apparatus of answering of setting pulling force, pipe of cement device for revolving and driving, bus cable device, device for measuring force, answer power apparatus to connect controller; Bus cable device comprises the seal wire dolly, drive the seal wire dolly does the reciprocating drive motors of constant speed degree with respect to pipe of cement, the pipe of cement device for revolving and driving drives pipe of cement by the rotating speed operation of setting, so that described silk twines by the pitch of setting on pipe of cement, be provided with instruction in the described controller and answer power apparatus to change stress, guarantee that the seal wire dolly acts on the regulating circuit of the stress basically identical on the described silk in backhaul and feeding process.

Establish in the regulating circuit in the described controller record the initial setting parameter and with bus cable device, device for measuring force, answer that power apparatus, drive motors running state parameter and above-mentioned setup parameter compare, the program of computing, and according to above-mentioned comparison operation object command pipe of cement device for revolving and driving, answer power apparatus, drive motors to change running status and the PLC of the program moved according to initial set value.

The described power apparatus of answering is a direct current generator.

The utility model comes the stress of corrective action on silk according to the difference of seal wire trolley travelling direction (being the winding displacement direction) by controller.Given applied stress is done corresponding the adjustment by PLC according to the running status of relevant apparatus, and adjusted data are handled by digital governer.By feeding back to digital governer at a high speed after the device for measuring force mensuration steel wire actual stress, digital governer is controlled speed regulator according to the comparison result of the stress of adjusted stress and reality, answer the direct current generator of power apparatus by speed regulator control conduct, adjust small STRESS VARIATION in the time of both can guaranteeing unidirectional operation, consistent to guarantee actual stress with setting stress; Most critical be feeding, return the time, the stress that acts on the silk is consistent scarcely, system of the present utility model acts on the stress on the silk in the time of can being adjusted at feeding, return well.According to given winding displacement direction, PLC control frequency converter and winding displacement motor, thus make bus cable device with certain speed, to given winding displacement direction motion, finish the purpose that needs by certain distance, certain stress winding steel wire.
