On the table 1, a mechanism 3 for cutting windows in the card, a mechanism for gluing adhesive material into the window of the card and cutting down its central part, made in the form of a stamp 4 of combined action, a mechanism 5 for rewinding adhesive material, a mechanism 22 for gluing a microfilm frame are installed.

The card feeder includes a 1 endless conveyor 24 with spring grippers 25 mounted above the table and a card supply store 2. At the end of the table 1 is installed store 23 laying of ready-made cards.

* - To actuate the card processing mechanisms and the card feed mechanism, a drive shaft 31 is provided in the machine, which is connected via an eccentric 37 and thrust 30 to the window punching mechanism 3 in the card, via eccentrics 35, 36 and thrust 28,

29 - with a combined action stamp 4, through an eccentric 34 - with a mechanism 5 for rewinding adhesive material, through an eccentric 33 and thrust 27 - with a mechanism 22 for gluing a frame of microfilm into the card window and through an eccentric. 32, a finger - 43 - with a crank-lever mechanism consisting of a thrust 26, a knee-shaped lever 40, a rod 41, a pusher 42. Rotation of the drive shaft 31 is carried out by an electric motor 38 through a gearbox 39.

To ensure synchronization of the combined action stamp with respect to the card feeder, the device has a synchronization unit consisting of 28, 29 connected at one end with a combined action stamp and the other end with eccentrics 35, 36 of the drive shaft 31 and a crank-lever a mechanism that includes a thrust 26 connected at one end through a finger 43 to an eccentric 32 of the drive shaft 31, and the other end to an elbow-shaped lever 40 installed with the ability to interact through the rod 41 and the pusher 42 f course 24 card conveyer feeder.

The combined action stamp includes an upper plate 6 with a die-matrix 7, an ejector 8 with vacuum channels 9, a thrust 28 connected at one end with an upper plate 6, and the other through an eccentric 35 with a drive shaft. 31, the thrust 29 connected at one end with the ejector 8, and the other through the eccentric 36 with the drive shaft 31, the bottom plate 11, the mechanism for cutting out the frame of adhesive material, including a punch 12, whose working surface has a ν-shaped groove with pointed edges, and inside the body of the punch there are channels 13 for supplying compressed air ..

The combined action punch is also equipped with means for discharging adhesive material, including a spring-loaded puller 14, having an edge cut off at an angle, and a retractor removal retractor consisting of a pressure lever 10 installed with one end interacting with the spring-loaded puller 14 and the other end connected to the upper plate 6

For the supply of adhesive material in the stamp of combined action, the device is equipped with a mechanism 5 for rewinding adhesive material consisting

from the coil 15 with adhesive material 16, adhesives 18, 19 of the supply of adhesive material, the roll 20 of waste and the coil 17 of winding from the adhesive material of the protective film.

With the rotation of the drive shaft $ 31

through the eccentric 32, the finger 43 and the ratchet-lever mechanism consisting of thrust 26> knee lever 40, rod 41, push rod 42, an endless conveyor ... 24 card feeders are actuated, as a result, card 21 from the card feeder 2 is fed spring grip 25 infinite transporter '24 into the mechanism of 3 cutting windows in the card. In this case, the eccentric 37 at the ** of the water shaft 31 shifts the thrust 30 down, as a result of which the mechanism for cutting down the window in the card is triggered. At the time of further movement by the endless conveyor 24, the card with the window cut from it. The window punching mechanism in the card 3 moves to the stamp 4 of the combined action. The eccentric 35 of the drive shaft 31 moves the cradle 28 down, resulting in the top plate 25 6 of the stamp of the combined action With the die-matrix 7 installed on it and the pressure lever 10 also moves downwards. The adhesive material 16 with the protective film preliminarily removed from it and 30 wound onto the coil 17 is fed into the stamp of the combined action by the rollers 18, 19 of the adhesive material feed adhesive side down. 35

Upon further movement of the upper plate 6 downwards, the cutting of the frame of the adhesive material by the punch 12, the working surface of which has a ν-shaped recess with pointed edges, occurs. When this spring-loaded puller 14 is discharged downward by the pressure lever 10.

The frame of the adhesive material cut out in this way is moved to the surface of the ejector 8 by means of compressed air through the channels 13 provided in the body of the punch 12 and creating a vacuum in the vacuum channels 9 of the ejector 8. 50

As the drive shaft 31 rotates, the top plate 6 with the die matrix 7 and with the frame of adhesive material placed in it is retracted upwards, the pressure lever 10 releases the girth 55 reamer puller 14, which, at an angle cut off, resets the adhesive material to its original position, thus preventing its sticking to the punch 12. 60

This operation is carried out aha the turnover of the drive shaft 31.

For the next half turn of the drive shaft 31, the eccentric 32 through the finger 43 moves the thrust 26 up, 65

as a result, the knee-shaped lever 40 moves the rod 41 with the pusher 42 to the right, thus activating the endless conveyor 24, which feeds the card 21 with the window cut into the stamp 4 of the combined action.

The eccentric 36 of the drive shaft 31 moves the thrust 29 of the stamp combined action down, as a result of which the ejector 8 together with the frame of adhesive material moves also down and pastes the frame of adhesive material into the window of the card 21.

At this point, the drive shaft 31 is completing its full turn.

In the next rotation of the drive shaft 31, the card 21 is removed from the stamp of the combined action by the endless conveyor 24 and moves to the mechanism 22 for sticking a microfilm frame into the card window, and another card from the card supply store 2 is fed to the mechanism 3 for cutting the window in the card. At this point, the stamp 4 combined action cuts down a new frame of adhesive material. Then, as the drive shaft 31 rotates, the eccentric 33 moves the thrust 27 downward, as a result of which the mechanism 22 of inserting the microfilm frame into the card window is activated.

At the same time, the 3 window cutting mechanism in the card cuts the window in the next card, and the combined action stamp 4 pastes the cut frame of adhesive material into the window of the new card.

These operations are repeated and provide fast processing of cards filed successively from the store 2 card submissions.

• Gotovye cards are served in the store 23 stacking ready-made cards.

Introducing a mechanism for sticking adhesive material into the window of the card and punching out its central part, made in the form of a stamp of a combined action with the synchronization unit of its operation relative to the card feeder and equipped with a mechanism for cutting out the frame of adhesive material and means of resetting the adhesive material, significantly improves the performance of the device, simplifies its design and improves the quality of manufactured cards.
