Abstract
The present invention relates to a drive device for a marking press of a screen printing machine, which is characterized in that signals transmitted by AC servo motors (5, 15) are converted into digital signals by a converter (6), and the digital signals are transmitted to a digital servo unit (32), and thereby, a servo motor for driving a marking press (41) is rotated. A start point detector (30) detects a printing start point and generates signals, and the signals are transmitted to a pulse generator (31). The pulse generator generates a signal which can drive the marking press to start to vertically move, the signal is transmitted to the digital servo unit (32) in order to detect a printing position and simultaneously judge a start signal to carry out printing, and thereby, printing quality is improved.
Description
The present invention relates to the marking press drive unit of screen decorating machine, in more detail, the present invention relates to the marking press drive unit on the high-precision screen decorating machine.
The multiple device of the screen decorating machine of printed patterns on fabric etc. is disclosed at present, all automations of most presswork, and need use the automatics that drives belt for this automated job.
On existing screen decorating machine, the impression operation of the marking press on the silk screen of printing device is carried out with the certain intervals of simple setting, since not to below former satin position and the relative position between the belt of operation post compensate, behind long mechanical action, will cause correctly to carry out the problem of stamp.
Consider the problems referred to above, the marking press drive unit that the objective of the invention is to screen decorating machine is in belt drives and play under the point detection device effect, can impress operation in correct position and time.
In order to finish above-mentioned purpose, the silk screen drive unit of screen decorating machine of the present invention has the imprinting apparatus that the driven roller with belt drives linkedly.
Below, with reference to accompanying drawing, illustrate in greater detail screen decorating machine impression drive unit of the present invention.
Fig. 1 is that the integral body of the screen decorating machine of the expression marking press drive unit that is suitable for screen decorating machine of the present invention constitutes schematic diagram;
Fig. 2 is the structured flowchart of the marking press drive unit of expression screen decorating machine of the present invention;
Fig. 3 is the plane that expression is applicable to the screen apparatus on the marking press drive unit of screen decorating machine of the present invention.
Be suitable in the formation of screen decorating machine of marking press drive unit of screen decorating machine of the present invention (Fig. 1) in summary ground expression, drive the driven roller (1 of both sides, 11) AC servomotor (5,15), based on the belt drive of applying on the same day with the application, also have the formation that can compensate, this formation is with following summarily described identical.
The belt (10) that becomes the stamp operation post is sleeved between the driving driven roller (1) and driven roller (11) at two ends, and this belt (10) is a rotating vulcanie system belt, among the figure, and the 9th, be used for the silk screen unit of stamp.The AC servomotor (5,15) that drives each driven roller (1,11) drives driven roller (1,11).Raise between the clothes motors (5,15) at driven roller (1,11) and AC and to have assembled reductor (4,14), the winding number of AC servomotor (5,15) is transformed into digital information and is given control module (7) respectively with it by converter (6,16).
Programming roller (2, the 12) identification and driven roller (1 that fuse and rotate with driven roller (1,11), 11) information that winding number is relevant, and give row programming unit (3,13) with this information conveyance, and then the information relevant with this revolution carried out digitlization, afterwards, flow to control module (7).In control module (7), by the row programming unit (3,13) drive revolution numerical value the now of carrying and flow to counter, compare with deviation the counter value that will count and the setting value that is stored in the memory, then this departure is transformed into the analogue value, add AC servomotor (5,15) offset, this compensation winding number feeds back to drive circuit again, and continuous continuing carry out feedback compensation repeatedly, till turning round with the offset that calculates.
In this device, by converter (6,16) information conversion of the driving winding number of AC servomotor (5,15) is become data signal, flow to control module (7) then.The information of this driving servomotor also can be by also can be used as order wire etc. the marking press drive unit of the present invention of transmitting device transmit.
In Fig. 2, by will be in the converter (6) from AC servomotor (5,15) signal converts data signal to, has at the moment figure signal of this converter (6) and can carry out the effect that the position that detects present belt position (being the position of the former satin on the belt) detects machine.Signal from converter (6) is transported to digital servo unit (32), and the servomotor (40) that drives marking press (41) is rotated.
According to the various detecting sensor (not shown)s of judging each test point on the belt, starting point detects machine (30) and utilizes the start point data input unit (35) of initial setting to detect the stamp starting point.
The signal that detects machine (30) from this starting point is fed to impulse generator (31), produce the vertical mobile commencing signal of a stamp axle (not shown go out), and transmit signal to digital servo unit (32), so that make marking press (41) on silk screen (43), be in the stamp wait state, when detecting the stamp position, read the starting point signal and carry out stamp.
Because the display unit of the data of display setting and most impression operations are carried out simultaneously, so, also be provided with communication channel (33) for controlling it.
Carry out stamp by the movable signal and the starting point that detect above-mentioned belt simultaneously, just can compensate the variation of stamp position, and, can on correct position, carry out stamp.
