Abstract

The utility model discloses an automatic tray centering control system of a paper discharging machine. The automatic tray centering control system of the paper discharging machine comprises a touch screen, a programmable logic controller (PLC), an encoder, a frequency converter and a tray centering mechanism, wherein the tray centering mechanism comprises a driving motor and a tray positioning arm. The automatic tray centering control system of the paper discharging machine is characterized in that the touch screen is electrically connected on a communication port of the PLC, the encoder is electrically connected at an input end of the PLC, an output end of the PLC is in electric connection with the frequency converter, the frequency converter is in electric connection with the driving motor, the tray positioning arm is connected on an output shaft of the driving motor, and the encoder is mounted on the driving motor. The automatic tray centering control system of the paper discharging machine can automatically control the center of a tray to be aligned with the center of paper accurately, and can substantially save labor cost of a printing plant.

Description

A kind of pallet automatic centering control system of unloading the paper machine

Technical field

The utility model relates to a kind of pallet automatic centering control system of unloading the paper machine.

Background technology

Unloading the paper machine is the machine that a kind of paper that paper cutter can be cut fitly is stacked into buttress automatically, is the important component part that cuts in the production line.Paper cutter on the traditional sense after paper cutting is finished, must utilize logistics means of transports such as hydraulic trolley that the paper that the workman is stacked into buttress by hand is carried to printing station with manually paper being transported on the pallet of transporting sheets.This mode labour intensity is very big, carries out the occupational disease that this carrying may cause the back discomfort for a long time.Unloading paper machine major function is exactly in order to replace this carrying action, to reduce working strength of workers.

During the sheet-fed printing stacking mode of paper on pallet there is strict requirement. shown in Fig. 1 a and Fig. 1 b, paper 20(length is that L, width are W) have footing 150 with respect to pallet 15() placed in the middle about needing, be the left and right end of the left and right end of paper 20 and pallet 15 A that keeps at a distance, the dimension delta that paper 20 rear end faces expose the back end edge of pallet 15 need guarantee at 0～5mm.On the traditional printing technology, this operation be the workman by hand stacking finish.So the paper of coming from cut paper station transportation must be is again put in order again and stacking by the workman of printing station, prints to " flying to reach " on the ability.Therefore demand urgently having a kind of automatic control system to solve this problem.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of pallet automatic centering control system of unloading the paper machine to be provided, the center that it can control pallet automatically exactly with the centrally aligned of paper, the cost of labor that can significantly save the printing house.

The technical scheme that realizes above-mentioned purpose is: a kind of pallet automatic centering control system of unloading the paper machine, comprise touch-screen, Programmable Logic Controller, encoder, frequency converter and pallet centering body, described pallet centering body comprises drive motors and pallet registration arm, wherein, described touch-screen is connected electrically on the PORT COM of described programmable controller, described encoder is connected electrically on the input of described programmable controller, the output of described Programmable Logic Controller is electrically connected with described frequency converter, described frequency converter is electrically connected with described drive motors, described pallet registration arm is connected on the output shaft of described drive motors, and described encoder is installed on the described drive motors.

The pallet automatic centering control system of the above-mentioned paper machine that unloads, wherein, described pallet registration arm is connected with the output shaft of described drive motors by reductor.

Technical scheme of unloading the pallet automatic centering control system of paper machine of the present utility model, constituted by touch-screen, Programmable Logic Controller and encoder etc., by Controlled by Programmable Controller pallet detent mechanism, the center that reaches automatic control pallet exactly with the purpose of the centrally aligned of paper, need not just can directly go up " flying to reach " by managing with stacking of printing station again prints, significantly save the cost of labor of printing house, can also provide for follow-up printing precision reliably to guarantee.

Description of drawings

The stacking structural representation of paper on pallet when Fig. 1 a is the sheet-fed printing;

Fig. 1 b is the side view of Fig. 1 a;

Fig. 2 is the structural representation that unloads the pallet automatic centering control system of paper machine of the present utility model.

The specific embodiment

In order to understand the technical solution of the utility model better, also be elaborated by reference to the accompanying drawings below by specific embodiment:

See also Fig. 2, a kind of pallet automatic centering control system of unloading the paper machine of the present utility model, be used for making the center of unloading the paper that the paper machine unloads and the centrally aligned of pallet, this control system comprises touch-screen 1, Programmable Logic Controller 2, encoder 3, frequency converter 4 and pallet centering body, the pallet centering body comprises drive motors 5, reductor 6 and pallet registration arm 7, wherein

Touch-screen 1 is connected electrically on the PORT COM of programmable controller 2;

Encoder 3 is connected electrically on the input of programmable controller 2;

The output of Programmable Logic Controller 2 is electrically connected with frequency converter 4;

Frequency converter 4 is electrically connected with drive motors 5;

Reductor 6 is connected on the output shaft of drive motors 5;

Pallet registration arm 7 is connected on the output shaft of reductor 7;

Encoder 3 is installed on the drive motors 5.

A kind of operation principle of unloading the pallet automatic centering control system of paper machine of the present utility model is:

By touch-screen 1 or the automatic detection function of paper by unloading the paper machine length of paper is input to Programmable Logic Controller 2; The specification of pallet is input in the Programmable Logic Controller 2 by touch-screen 1; Because the center of paper is relevant with the size of paper, the center of pallet is relevant with the size of pallet, after these two variablees are determined, programmable controller 2 just can calculate the distance that pallet registration arm needs move according to the length of paper and the size of pallet, Programmable Logic Controller 2 is passed to signal frequency converter 4 again, make drive motors 5 operations by frequency converter 4, drive motors 5 drags pallet registration arm 7 by reductor 6 and moves, when moving, pallet registration arm 7 feeds back its actual displacements by encoder 3, when the displacement of pallet registration arm 7 reaches the numerical value that needs that Programmable Logic Controller 2 calculates move, Programmable Logic Controller 2 sends stop signal, control frequency converter 4 makes drive motors 5 out of service, this moment pallet lean against on the pallet registration arm 7 center that the back guarantees pallet exactly with the center-aligned of paper.

Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
