Description

Lisk 7 with grooves 8 for needles (each of which is calculated on one needle) on a cylindrical surface, shaft 9 on which a disk 7 and a disk 10 with fingers 11 are fixed to a key and the number of which is equal to the number of grooves of disk 7, with the figured cam 4 installed with the possibility of engagement with the fingers 11.

A needle feeder with a hopper includes a hopper 12 with a vibrator 13, a feeder 14 mounted above the disk 7, the cutout of the dispensing mouth of the feeder 14 being located less than the diameter of the needle from the cylindrical surface of the disk 7.

The presser pin with the drive mechanism comprises a presser pin 15, mounted spring-loaded in a rigidly mounted sleeve 16, the tab being pivotally connected to the connecting rod 17, the second end of which is mounted on the fixed axis 18, and the middle part is provided with a roller 19, which is in position of the presser from the spring-loaded pin 15 with the figured cam 5 of the drive shaft 2, and the axis of the possible movement of the pin 15 lies in the plane of the disk 7.

The hopper cannula feeder consists of a hopper 20 under the cannula and an inclined mounted feeder 21 under the hopper 20.

The cannula support includes a plate 22, spring-loaded spring 23, one end of the plate is rigidly fixed, and three ridges 24 are installed at its free end under the mounting dimensions of the cannula, and there is a rounded shoulder 25 on the upper side of the plate, and ridges 24 are located below the cutter of the cannula at a distance nii not less than 1/2 of the largest diameter of the cannula.

The pusher with a drive mechanism includes a pusher 26, made in the form of a stepped bushing with shoulders 27 along the outer and shoulders 28 along the inner contour, with a spring-loaded centering pin 29 inside; a connecting rod 30 connected to the disk 6 at its eccentric point and with a two-arm lever 31 mounted on a fixed axis 32, the second end of which is pivotally connected to the pusher. The pusher 26 is mounted so that the axis of the centering pin 29 of the pusher 26, the intersection of the axis with the axis of movement of the presser bar 15, is coaxial with the axis of the cannula mounted on the ridge 24 of the plate 22 and the axis of the needle installed in the groove 8 of the disk 7 when the groove is positioned Pressing position.

The device works as follows. The rotational moment from the electric motor 1 is transmitted to the pulley 3 of the shaft 2, the figured cams 4 and 5 and the disk 6.

The figured cam 4, when rotated 360 °, engages with one of the fingers AND of the disk 10, rotates the disk 10 to the position of one of the slots 8 of the disk 7 under the dispensing mouth of the feeder 14, from which one needle enters the groove and another 7 with the needle is mounted coaxially to the pusher 26,

after which the cam 4 disengages from the finger 11. When rotated for the next 360 °, the cam 4 engages again with the next finger 11, rotates the disk 7 in the indicated manner through the disk 10 and disengages from the finger 11.

The figured cam 5, turning with the shaft 2 by 360 °, allows the clamping pin 15 under the action of the spring sleeve 16 to

under the action of the spring sleeve 16 to implement

Ska 7 located in the press position

(pusher pivot pin

26).

The disk 6, turning with the shaft through 360 °, moves the ends of the two shoulders lever 31 and through the connecting rod 30 informs the pusher 26 one reciprocating movement. When this centering pin 29, the passage through the opening of the cannula, is the tip of the hole

needle mounted on the press-in position and the presser pinch 15 pressed. At this point, the cannula hangs on the centering pin 29. With further movement of the pusher forward, the collar 27 of the pusher advances onto the rounded collar 25 of the plate 22, the last one is recessed. Upon further advance, the pusher 26 presses the cannula onto the needle, while the spring-loaded centering pin 29 remains in place.

In the return movement, the pusher 26 of the cannula, which remains pressed on the needle, is removed from the pin 29.

When the pusher 26 returns to its initial position, the cannula drops out of the feeder 21, being mounted on the ridges 24 of the plate 22, which returns to its original position by this moment when releasing the round collar 25 of the collar 27 of the pusher 26.

Turning shaft 2 to the next 360 °

the cycle repeats. The needle with the cannula pressed on it, being released from the presser pin 15, drops out of the groove 8 into the receiver / is not shown in the drawing /. Needles and cannulas are loaded into portions of the hopper 12.

needles and in the bunker 20 cannulas.

Claims (1)

Invention Formula A device for pressing in parts, preferably needles with cannulas for the blood transfusion system, comprising a disk mounted on the base with needles, an intermittent rotation mechanism of the disk, a pusher located coaxially with a disk slot, a pusher drive kinematically associated with a disk intermittent rotation mechanism, characterized in that, in order to increase productivity, it is equipped with a single piece dispenser of needles in the disk slots mounted on the base; the cylindrical surface of a vertically positioned disk having grooves for needles, cannula delivery mechanism at the pressing position, also made in the form of a hopper pivotally mounted on the basis of a spring-loaded support with a protrusion, which is pushed by the pusher to be flung before the cannula is pressed in, as well as the needle pressing mechanism against the disc the pressing positions, made in the form of a pin mounted on the base and iodonflated, periodically in contact with the needle and driven by a cam, kinematically connected with the mechanism of intermittent rotation of the disk and the drive of the pusher. uz.t oh l- I { Iql
