CS224918B1 - The winding head of the automatic machine for the roll films - Google Patents

Description

The invention relates to a winding head, a reel of photographic roll films. .

The most widespread is a manual method of bobbing photographic films where no similar device is used. This type of bobbin is very unproductive and requires work in the dark. In the known bobbin semiautomatic machines, some operations, such as inserting the bobbins and orienting them, are carried out manually. Again, this is work with low productivity and in the dark.

The complex automation of the winding head operations is. solved solely in the coil automat In coonsrripšnuhio 'solution'. the soldering head of the coil automat. are known as 'fyio-two' - ways:

a) The winding head is designed as', two-position: 'one' position is insertion, the other - winding · When the head is turned, the coil is orientated and the finished coil is ejected. This winding head i does not allow work in the light, the whole machine can work.only in the dark. j

b) The nailing head is solved. as a three-point turnstile:. one position is the insertion and serves at the same time to orient the coil, the other position is. Retractable and third ejection. - The first and third positions are in the light, the second is in the light-tight enclosure. When reversing the turnstile .. it is always necessary to open and close the door closing - the working space.

The above-mentioned drawbacks are eliminated by the retractable head of the reel of the photographic roll film, located in a light-tight housing, the essence of which is a twin winding spike, of which at least one spike is axially adjustable, whereby to the axis

The 224 918 prongs are guided by a 4 " tafilm material and a cover strip guide spout, against which a spool feeder is disposed including spool orientation projections and wherein a pinch roller provided with flexible fingers for gripping the cover strip and below the spike axis a switch, connected to the defect identification sensors of the machine material.

The benefit of the invention of the winding head is to simplify and accelerate the work of winding coil films with cover strips by combining operations of transport and orientation of the spool, operations of ejecting the finished coil and clamping of the empty spool, which allows simplification of design and control mechanism. The solution of light-tightness of all input points of individual materials and output of the finished coil allows to perform all operations under any lighting. The whole device is light-tight.

че. The winding head is shown in the attached drawing, on the vМ nailed on ЛП. 1 _of, 'equipment and sequence of individual operations is as follows:

After passing through the coil inlet 1, the coil is removed by a segment 2, which passes it to the barfeeder. The barfeeder J orients the coil and feeds it between the clamping tip 4 ^{and the} winding tip.

The beginning of the cover strip is inserted between the feed rollers 6 and 2, which are conveyed under the raised light curtain 8 and further by means of a guide nozzle 8 into the opening in the coil. The light curtain 8 closes. The winding tip J starts to rotate after passing the film through the optical sensor 10. The tip rotates the spool and winds up the cover strip. The resilient fingers located on the pressure roller 11 prevent the beginning of the cover strip from re-sliding out of the spool. The wrapping of the cover strip is synchronized with the motion of the film so that after insertion of the film into the coil, the film is positioned exactly according to the printing of the cover strip. Upon introduction of the film into the coil, the lever 12 opens the guiding spout 2 to prevent the folded end of the cover strip from straightening and premature sealing of the coil. Just before the curved end has passed under the light curtain 8 so, it is raised. After complete winding, the roll is perfectly pressed by the pressure roller 11

- 3224 918 sealed. The clamping tip 8 extends, the ejector 13 withdraws the coil from the winding tip J, and the coil falls through channel 14 onto the turnout flap 15. The turnout flap is controlled by the electronics of the spooling machine and discards the illuminated or otherwise defective finished coils into scrap.

Claims (1)

SUBJECT OF THE INVENTION 224 918 A winding head of a photographic roll film reel dispenser disposed in a light-tight housing, characterized in that it consists of a pair of winding spikes (4,5). of which at least one prong (4) is axially displaceable, wherein a fimmable maaerial kite and a cover strip guide (9) are guided to the axis of the prongs (4, 5), against which a spool feeder (3) comprising spool orientations and wherein a pinch roller (11) provided with resilient fingers for the pin is further associated with the axis of the spikes (4,5). capturing the beginning. and where below the axis of the spikes. (4.5). a crossover (15) is provided, communicating with the material defect detectors located in the machine.
