Description

The proposed mechanism has been set-; It is used on flat-printed printing machines of the Millet type and serves as an I for automatic acceptance of printed sheets, eliminating possible bends and misalignment of the sheets, as well as giving them very accurate laying.

In FIG. 1 shows a schematic movement of the pelt; FIG. 2- a general front view of the self-receiver; FIG. 3 is the same side view; FIG. 4 is a section along AB of FIG. 3 buttons, including the work of the self-receiver; FIG. 5-side view of tweezers, receiving the printed sheet in the open form; FIG. 6 is the same in plaka; FIG. 7-side view of closed tweezers; FIG. 8 is the same in terms of; FIG. 9-forks on the inner side of the car of the left carriage, on which the mechanism of rotation of the roller of the upper valve of the tweezers is installed; FIG. 10 is the same, side view; FIG. 11- a view, from the inside of the machine, of the right carriage, on which the mechanism of rotation of the roller, giving movement to the lower valve of the tweezers, is installed; .fig. 12 same side view.

The self-rider receives movement from the shaft of the machine 1 by means of a chain transmission transmitting movement to the roller 2; on the latter the crank 3 is fixed, which

(25)

through the rod 4 transmits the swinging movement of the lever 5; the latter, with its upper end sitting on the roller 6, is not wedged and can freely rotate on the same roller in a wedged position. ROW. The lever 5 is fixed on the roller on the hinge lever 7 (Fig. 4), having a deactivating pin 8 at the lower end. When pin 8 is on (as shown in the drawing), swinging the lever 5 causes lever 7 to swing and roller 6 is rotated with it; if the pin 8 is turned off, the lever 5 is rotated, and the lever 7 and the roller 6 remain at rest. On the roller 6 on the key, the lever 9 is fixed, the other end coupled to the lever 10, which is set on the roller end And, reinforced with the ends (without the possibility of rotation) in the right and left carriages 12, 13. Thus, if the roller 6 turns, then this will cause the carriages to move up and down along the guides 14.

Between the carriages (Fig. 2) reinforced, in addition to the roller And, two more rollers 15 and 16, with the possibility of rotation. A guide box 17 with a cheek 18 in which the lower flap of the 19 tweezers 19 is moved on the roller 11 (Fng. 5 and 6) and has

the roller 20 and being turned off by a spring 21 fixed on the rear end of the cheek 18. The guide box 17, depending on the paper size, can move along the roller 11 along a long key and is fixed in the lower position by a locking screw.

On the roller 15, the upper valve of the tweezers 22 is strengthened, which, if necessary, can also be moved along the roller. On the roller 16, the lever 23 is reinforced, with the upper edge in contact with the roller 20 and also having movement along the roller. When the carriages are raised to the upper position, and the tweezers are at the level of the received sheet, the roller 16 rotates and the lever 23 rotates to apply pressure to the roller 20, which causes the lower valve 19 to slide out; at this time, the roller 15 is rotated, and the upper valve 22 is lowered, clamping the received sheet between the valves, the protrusion located on the lower side of the upper valve falls into the recess of the lower valve and does not allow the latter, pulled by the spring 21, to take off . Then the lowering of the carriages occurs, and the sheet is folded over for acceptance. A bit of no income before acceptance, the valves open; the lower valve released and spring-loaded, the lower valve quickly takes its extreme off position, so as not to touch the already folded sheets; the upper one has a slower movement, an argument to the very acceptance. The rotation of the roller 15 (Fig. 9 and 10) is achieved by a mechanism mounted on the left carriage 12. In the carriage having guides with a cheek 24, the ruler 25 moves; at its upper end there is a reinforced roller 26, and in this roller, the free end is a lever 27, which sits on a tongue on a roller 15. A free end 27, which lies on the roller 26, is pulled away by a 8LOW spring 28, mounted on the cheek 24. The ruler at its bottom the part has a notch into which the pawl 29 presses against the plate spring 30. When the carriage rises to the upper position, the pawl 29 hits the stop screw 31 with its upper end, which causes it to deflect and release the ruler 25, and the latter, having released, goes down down and with it goes down and the free end of the lever 27, which lies on the roller 26 and is pulled down by the stem {other 28. Together with the rotation of the lever 27, the roller 15 also rotates, and he is sitting on the tongue. When the carriage is lowered to the lower position, the ruler 25 hits the stop of the rack 32, which causes the ruler to raise with the guide and the roller 26, reinforced in its upper part, to raise the release end of the lever 27, which causes the roller 15 to turn At the same time, the pawl 29, pressed by the spring 30, falls into the recess in the lower part of the ruler 25 and holds it upright. The rotation of the roller 16 is achieved (Fig. 11 and 12) by a mechanism mounted on the right carriage 13. In the carriage having guides with the cheek 33, the ruler 34 moves; A roller 35 is fixed on the ruler at the bottom and with this roller the lever 36, which sits on a key on the roller 16, is in contact with the free end, and all the time it tends to occupy its upper position (as shown in the drawing); this is a consequence of the fact that, as stated above, the spring 21 is pulled off by the lower valve 19 to the off position, and the last one, by the roller 20 exerting pressure on the lever 23, the roller 16 is turned; In this way, the Liegegeka 34 occupies its top position. When the carriage rises up, the ruler 34 abuts against the stop 37 and lowers down along the guides, pushing the roller 35 to the free end of the lever 36, as a result of which the latter lowers and causes the roller 16 to turn.

Since, as the sheets are received, their level increases all the time, it is necessary that, with the carriage's upper position remaining unchanged, their lower position all the time should change towards increasing the height of the foot of the received sheets,

This is achieved by the fact that at the bottom (Figs. 2 and 3) a roller 38 is installed, which lies in the bearings 39; after the end of the roller, the ratchets-40 are put on the spigot j and 41 is freely seated; they both have | an identical small tooth looking in one direction, and between them a replaceable ratchet 42 (depending on the thickness of the paper received) is installed with large gaps between the teeth and also freely sitting on the platen and connected to the ratchet 41 by a screw 43. On the ratchet 41 lies doggie 44; the ratchets 40 and 42 overlap the dog 45, and both dogs are fastened to the bar 48, screwed to the ruler 47, located in the guides 14 and in its upper part having a pin 48. With each raising of the carriage, the last notch at her lift engages the pin 48 and slightly raises the ruler 47, which then, under the action of the spring 49, returns to its lower position. When lifting, the doggie also rises, and the doggie 44 turns the ratchet 41 by one tooth at each lift, the doggie 45 slides over the surface of the ratchet 42 (as it has a rare tooth) and does not get into the ratchet tooth 40. When the ratchet 41 turns, the ratchet 42 Tkkzhe rotates (spring 50 is attached to the ratchets, protecting them from free spinning) and when turning the ratchet 41 by several teeth, ratchet 42 brings the tooth 45 under the dog 45; at the same time, the latter catches, and the ratchet tooth 40 and rotates the last one tooth, after which several idle movements of the pawl 45 follow again until the next ratchet tooth 42 is brought under it, after which the ratchet 40 is turned again by one tooth.

Since the ratchet 40 sits on a key on the roller 38, when the ratchet turns, the roller rotates, and on the last, also on the key, the gear 51 sits, which engages with the toothed rack moving in the rails. Through the above mechanism, a very fine adjustment of the toothed rack is achieved, the upper end of which serves as a baffle for opening the valves and fixes the lower position of the carriage. In order to hold the toothed rack in a raised position, as it perceives the rigidity of the carriages, it tends to lower, on the ratchet 40 lies the doggie 52, which does not give it the possibility of a reverse rotation.
