Description
Technical field
The present invention relates to a kind of cold wave technique, be specifically related to a kind of sheet cold wave technique.
Background technology
Sheet refers to not have to form continuously the stock of web-like, and they independently become to open and discontinuous separately, and common sheet is paper.The stamping systems film comprises metal species stamping systems film and non-metal kind stamping systems film, and metal species stamping systems film is such as vacuum aluminum-coated cold stamping film or electrochemical metal film etc. are arranged.Thermoprint material bed (for example aluminium coated) is arranged on the stamping systems film.Sheet cold wave technique is exactly with the material bed technique that is transferred on sheet of the thermoprint of stamping systems film.
The production technology of existing sheet cold wave transfer printing is as follows: coating mechanism needs the local location of thermoprint to coat adhesive (for example UV oil) on the surface of sheet, then, paper-transferring gripper by chart driving mechanism is held in the mouth, lining roller to eindruckwerk transmits, when the paper-transferring gripper of chart driving mechanism run in the lining roller groove of eindruckwerk hold the mechanism of paper side in the month the time, the mechanism of paper of holding in the month that stock is served as a contrast in the roller groove connects away; The mechanism of paper drive stock rotation of holding in the month of lining roller groove advances to below roller platen; Meanwhile, stamping systems film unreeling structure is also carried the stamping systems film through eindruckwerk continuously; Roller platen compresses lining roller and synchronous the rotation, make stamping systems film and sheet pressing and advanced in unison, the position that scribbles adhesive on stock sticks the thermoprint of stamping systems film is material bed, make on the thermoprint material bed thermoprint position (coating the position of adhesive) of transferring to stock, after this adhesive solidifies (can utilize curing mechanism to solidify, also can spontaneous curing); After impression, the stamping systems film becomes useless film, and useless film winder structure does not stop useless film is batched and rolling, and the mechanism of paper of holding in the month of the lining roller groove of eindruckwerk discharges sheet, complete thermoprint, the material bed just cold wave of the thermoprint on the stamping systems film is transferred to the position that scribbles adhesive on sheet.
Shown in Figure 1, in the thermoprint process, must there be gap (as shown in EA in Fig. 1) on operating path between adjacent two sheets 11, and in each sheet of printing stock, hot stamping pattern also often just is distributed in the subregion of stock, and (zone of this part is called the thermoprint zone, as regional in the KG zone in Fig. 1 or BC, HK in Fig. 1, GE, AB, CD are not the thermoprint zones), between the forward position of the front end in thermoprint zone 12 and stock 11 from a distance, between the rear end in thermoprint zone and the rear edge of stock also from a distance.shown in Figure 1, in present specification, position, point of contact under lining roller 41 and roller platen 42 stitching states in eindruckwerk is called " pressing point " (as the point of the F in Fig. 1), stock 11 in the thermoprint process is called " stock forward position " (as the point of the A in Fig. 1 or H point) through the position of eindruckwerk pressing point at first, stock in the thermoprint process is called " edge after stock " (as the point of the E in Fig. 1 or D point) finally by the position of crossing eindruckwerk pressing point, stock thermoprint zone in the thermoprint process is called the front end of zone " thermoprint " (as the point of the K in Fig. 1 or B point) through the position of eindruckwerk pressing point at first, stock thermoprint zone in the thermoprint process is called the rear end of zone " thermoprint " (as the point of the G in Fig. 1 or C point) finally by the position of crossing eindruckwerk pressing point, will the front end of zone " thermoprint " and the rear end of zone " thermoprint " between be called " thermoprint zone length " apart from length, length as BC in Fig. 1 or KG, to be called " front neutral gear length " apart from length between " stock forward position " and the front end of zone " thermoprint ", length as AB in Fig. 1 or HK.After the hot stamping pattern design of stock was completed, the position of thermoprint zone on stock just decided, and the numerical value of " thermoprint zone length ", " front neutral gear length " is also just decided.
there is following limitation and not enough in present sheet cold wave technique: shown in Figure 1, owing to existing certain neutral gear stage (namely not need to shift the material bed stage of thermoprint between twice of front and back hot stamping pattern KG and BC, as the GB stage in Fig. 1), comprise gap (the front neutral gear that exists between " stock forward position " and the front end of zone " thermoprint ", as shown in AB in Fig. 1), clearance distance (the rear neutral gear of existence between " after stock along " and the rear end of zone " thermoprint ", as shown in GE in Fig. 1), gap (the middle neutral gear that also exists between two sheet of printing stock, as shown in EA in Fig. 1), and in the cold wave process, the stamping systems film of rolling is ceaselessly operation forward always, so, the thermoprint of the stamping systems film that above-mentioned neutral gear place is corresponding material bed (as aluminium coated) is not transferred on sheet, directly swept away by useless film wrap-up and become useless film, cause waste, the utilization rate of stamping systems film is very low, increase the cold wave cost.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and a kind of sheet cold wave technique is provided, it can save the stamping systems film, improves the utilization rate of stamping systems film.
Its purpose can realize by following scheme: this sheet cold wave technique comprises the following steps:
(1), choose and determine the size dimension of every sheet of printing stock, design position, shape and the size of hot stamping pattern;
(2), stamping systems film unreeling structure constantly discharges the stamping systems film, the stamping systems film runs between the lining roller and roller platen of eindruckwerk; Coating mechanism is coated adhesive in the thermoprint zone of every sheet of printing stock, then held in the mouth by the paper-transferring gripper of chart driving mechanism, lining roller to eindruckwerk transmits, be provided with groove in the lining roller of eindruckwerk, be provided with in groove and hold mechanism of paper in the month, when the paper-transferring gripper of chart driving mechanism run to lining roller groove hold the mechanism of paper side in the month the time, the mechanism of paper of holding in the month that stock is served as a contrast the roller groove connects away; The mechanism of paper drive stock rotation of holding in the month of lining roller groove is advanced; During normal impression, roller platen compresses lining roller and synchronous the rotation, stock and stamping systems mould are closed, and make stock and stamping systems film advanced in unison, the position that scribbles adhesive on stock sticks the thermoprint of stamping systems film is material bed, makes on the thermoprint material bed hot stamping pattern position of transferring to stock; This relief adhesive solidifies; After the stamping systems film was stamped, the stamping systems film became useless film, and useless film winder structure does not stop useless film is batched and rolling, the holding the sheet release that mechanism of paper will impress in the month of lining roller groove and complete the hot stamping process process;
It is characterized in that, in above-mentioned steps (1), front neutral gear length numerical value and the thermoprint zone length numerical value of every sheet of printing stock of designing is input to central controller;
In above-mentioned steps (2), constantly detected the rotational angle of lining roller by angle measurement equipment, testing result is sent to central controller, central controller is according to the data message of angle measurement equipment measurement result and step (1) input, the turned position of stock thermoprint zone front end and rear end on judgement lining roller;
When the thermoprint of stock zone front end is through pressing point on serving as a contrast roller, push serve as a contrast roller platen to roller, make roller platen and lining roll-in tight, implement described normal impression; And in normal moulding process, the movable roll that drives the coating materials draw off gear that is positioned at the eindruckwerk upstream moves the stationary roll near the movable roll upstream and downstream, and the coating materials running orbit line length of eindruckwerk upstream is shortened, and the coating materials draw off gear discharges coating materials; In normal moulding process, drive the movable roll of the useless film draw off gear that is positioned at the eindruckwerk downstream away from the stationary roll of movable roll upstream and downstream, the useless film running orbit line length in eindruckwerk downstream is extended, useless film draw off gear stores the useless film of a part; In normal moulding process, stamping systems film unreeling structure continues not park volume, useless film winder structure continues not suspend volume, and the length that the coating materials draw off gear discharges coating materials adds that unreeling length equals to impress length, and the length that useless film draw off gear stores useless film adds that rolling length equals to impress length;
When the process pressing point of the rear end, thermoprint zone of stock on central controller judgement lining roller, above-mentioned normal moulding process finishes, beginning neutral gear process; In the neutral gear process, roller platen is pushed away the lining roller, roller platen no longer is pressed on the lining roller; And in the neutral gear process, drive the movable roll of the coating materials draw off gear be positioned at the eindruckwerk upstream away from the stationary roll of movable roll upstream and downstream, the coating materials running orbit line length of eindruckwerk upstream is extended, the coating materials draw off gear stores coating materials; In the neutral gear process, drive the movable roll of the useless film draw off gear be positioned at the eindruckwerk downstream near the stationary roll of movable roll upstream and downstream, the useless film running orbit line length in eindruckwerk downstream is shortened, useless film draw off gear discharges useless film; In the neutral gear process, stamping systems film unreeling structure continues not park volume, and useless film winder structure continues not suspend volume, and the length that the coating materials draw off gear stores coating materials equals to unreel length, and the length that useless film draw off gear discharges useless film equals rolling length;
When the regional front end process of the thermoprint of next sheet of printing stock pressing point, above-mentioned neutral gear process finishes, the normal moulding process of beginning next round; So constantly circulation.
In present specification, the effect of " coating materials draw off gear " is the coating materials of a segment length temporarily can be stored, and when needed the coating materials that stores is discharged.The coating materials draw off gear includes movable roll, stationary roll, and the upstream of movable roll and downstream all are mounted with stationary roll; When movable roll moves away from its upstream and downstream stationary roll, the coating materials running orbit is extended, and realizes that thus coating materials stores; When movable roll moves near its upstream and downstream stationary roll, the coating materials running orbit is shortened, and realizes that thus coating materials discharges.The structural principle of " useless film draw off gear " is identical with " coating materials draw off gear ", only " coating materials draw off gear " is positioned at the eindruckwerk upstream, the film of its storage is the film without impression, so be called " coating materials draw off gear ", and useless film draw off gear " being positioned at the eindruckwerk downstream; the film of its storage is through the film (useless film) of impression, so be called " useless film draw off gear ".
So-called " impression length " refers in a normal moulding process, and coating materials or stock advance and the total length of pressing." unreeling length " of so-called normal moulding process refers to that stamping systems film unreeling structure unreels total length in a normal moulding process; " the rolling length " of so-called normal moulding process, refer to useless film winder structure in a normal moulding process the rolling total length.Equally, " unreeling length " of so-called neutral gear process refers to that stamping systems film unreeling structure unreels total length in a neutral gear process; " the rolling length " of so-called neutral gear process, refer to useless film winder structure in a neutral gear process the rolling total length.
So-called neutral gear process is exactly two gap processes between normal moulding process, owing to not impressing in the neutral gear process, therefore claim " neutral gear process ".
The coating materials draw off gear stores the length of (or release) coating materials, and the coating materials running orbit line length that is exactly the coating materials draw off gear extends the variable quantity of (or shortening).Useless film draw off gear stores the length of (or release) useless film, and the useless film running orbit line length that is exactly useless film draw off gear extends the variable quantity of (or shortening).
