Works device for sealing ampoules as follows.

The hot ampoules are transported along a chain conveyor from a machine (not shown in the drawings) for the manufacture of ampoules to a filling mechanism 27 with an abutment 28.1, with which the corresponding ampoule is clamped. The shutter 29 fixed on yutang 28.2 is moved to return on-progressive 1K) to a healthy heartbeat of 30 (Fig. 2) in accordance with the working cycle. As a result, the ampoule is pushed between the open cheeks, which are opened by the pneumatic cylinder 12. When the ampoule is pressed against the clamping collet by the flap 29, the circuit 31 with the clamping collets is moved forward by one stroke.

To move the chain 31 forward, the sprocket 32 begins to rotate with the aid of the lever 33 and the connecting rod 34, which drives the storage mechanism (not shown).

The KAZ lever can turn on the axis 35 and the drive moves the curvature of the 1st (yy Ptaiboy ZV. The sprocket is supplied by one value equal to the distance between the next two one z.a the other clamping collet. In this case, the chain has Twenty-four clamping collets. For the direction of the collet, in addition to the driving sprocket, the directional wheels 37 are used. When the position B is reached, two clamping collets with

using an air cylinder 38 controlled in accordance with the working stroke with two actuators 39 and 40.

The ampoules are fed, after opening, their clamp b collet into the receiving prism 41, which performs vertical reciprocating movements. The receiving prism is fixed for this purpose on the rod 42 with the possibility of moving in the vertical direction in the direction of 43. The lever 45 is rotatably mounted on the axis 44, which is moved reciprocally using the pushrod 46 from the curvilinear guide 47. Transmitted from 47, through the pushrod 46 to the lever 44, the movement causes the receiving prism 41 to move up and down. When transferring the ampoules from the clamping collets to the receiving prism, the latter takes the highest position possible. After the transfer, it is omitted. When received, a prism forms part of a mechanism for transmitting, respectively, two ampoules of

transport conveyor, rotating with a higher number of cycles, in another transport conveyor, rotating with a lower number of cycles. For the transfer of the ampoules, there is a flap 48, which is located horizontally on two fixed

guides 49, and has at one end two pushers 50 which are on the same straight line with the ampoules dispersed on the lowered receiving prism 41. The gate 48 is brought into reciprocating motion with

using a mechanical drive (two-armed levers 51), turning one-sided reciprocatingly around the axis 52, overcoming the resistance of the spring 53, which end is made in the form of a fork 54, covers the roller 55

damper 48 (Fig. 5). For driving the lever 47, there is a connecting ipanga 56, which is adjacent to this lever and has a roller 57, which is cut along a curved guide 58.

Due to the reciprocating movement in accordance with the working stroke of the pushers 50, the amnulas are moved downward from the receiving prism 41 into two devices 59 for clamping ampoules. The latter contain four support rollers 15, 16, the holder 14 and

pusher 18. The holder 14 is held by the upper 60 and lower 61 chains. The spring 17 tends to press the rollers towards the holder 14 and the pusher 18 (Fig. 7).

Prior to the transfer of the ampoules from the receiving prism 41 to the devices 59, the push button is pressed. 18 seconds

By means of the 62, controlled in accordance with the working stroke of the air cylinder 63 up. As soon as the ampoules are pushed into the ampoule clamping devices, the direction of movement of the air cylinder changes, the pusher 18 mixes down and the ampoule is clamped using rollers as in a prism. Chains 60 and 61 move along sprocket wheels 64 and 65 arranged in pairs. Sprockets 65 are further moved by means of a distributor sprocket 66 and a curved distribution guide 67 (Fig. 3) in accordance with the working cycle into two divisions, i.e. by two vial clamping devices. A curved distribution guide is mechanically driven by a drive or a pre-activated ampoule making machine. Sprockets 64 and 65 are located on the hubs 68 and 69. The wheels, like hub 68 on shafts 70, are housed in bearing blocks 71, 72 (Fig. 3), which are mounted on a support plate 73 forming part of the frame 74.

From the clamping devices 59, the ampoules are fed to the region where the hollow needles 6 are located, which, being immersed by the front ends in the ampoules, blow them. Ten hollow needles 6 are located one from another at a distance equal to one division. Since the fixtures 59 move accordingly to double division, each ampoule can be blown five times with the help of needles 6, which are mounted on a flap 75 that can be moved on two stationary straps 76. An air cylinder is designed in the flap 75 to achieve reciprocating motion. (not shown). Hollow needles can be filled with sterilized filtered air or. rinse with gases.

Both rods 76 are connected to each other by means of a transverse rome 77 having a set screw 78 and a contour nut 79. The end of the pre-set viit forms a stop 80 for the transverse flap frame. Thus, using the set screw 78, it is possible to limit the lifting of the hollow needles 6, by distance, depending on the size of the finished ampoules.

The ampoule sealing mechanism rests on a slide 81, which, when reciprocating along two rods 82, retracts into bearing assemblies 83 and 84. During the drawing of the ampoules, the cheeks 21 and 23 of the drawing clamp collets are immersed inside the upper part of the ampoule. At the same time, the ampoules are heated by the burner 5, and the lifting points of the step 85 (Fig. 4) are moved to the left. As a result, the cheeks are moved apart and are adjacent to the inner wall of the ampoule. In the reverse movement of mechanism 4, the melted torch 5 ends of the ampoules separate from this mechanism and close.

During the drawing process, the vial should rotate. For this purpose, there are intended lower rollers 15, moving with the help of grinding wheels 86, which are driven by a rotating shaft 87 located under the support plate 73 and continuous (Fig. 2). The latter through the counter 88 (Fig. 3) rotates

The left conical. wheels 89 and 90, which engage with the conical wheels 91, which connect to the conical wheels 92 through the telescopic shaft 93. The conical wheels J 92 interact with the conical wheels 94, which are connected to the gears 95 and, rotated with them, are driven through an intermediate gear wheel 96 on each gear wheel 97 mounted on the shaft of the respective slant wheel 86 and

0 causes it to rotate.

The preservation of a constant length of vials is monitored by node 98 with stops located on pushers 99, which, having overcome the resistance of springs 100, can have reciprocating movements with skids 101 located on rods 102. In the area of stops there are two burners 103 and 104, one of which (103) serves to form the round heads of the ampoules, and the other (104) to heat the inside of the ampoules. After passing node 98, the vials are ready. On the bypass of the chains 60, 61 there is a mechanism 26 for monitoring the sealed tubes with eight measuring points. Each measuring point has a groping pin 105 and a groping head 106, which can

be set to a specific value and located on the pivot arm 107, which is located on the shaft 108, supported by two bearing supports 109, PO. The feeling pins 105 are supported by turning the MI with the levers 111 located on the shaft 112. If the ampoule is on the control mechanism 26, the groping pin 105 extends below the body of the ampoule, while the pivot arm I11 rotates in the direction opposite to the direction of the pull. arrows. Thereafter, the groping head 106 is lowered, which is set at a certain desired value. If the measurement result obtained is within the predetermined tolerance; that device 59 opens with a pusher

From the driven air cylinder 114 and the ampoule is pushed out.

Since the device operates in two cycles, two mechanisms are needed to determine the required value. Since it has a S with eight measuring measurements, the ampoules must be sorted into four different stages.

FIG. Figure 6 shows an embodiment where a pull-in clamping chuck with cheeks 115. 116 is applied, covering the end of the ampoule from the outside. The cheeks are pressed by springs 117, having wedge-shaped surfaces 118, to which an annular protrusion 24 is pressed, which controls the movements of the cheeks 115, 116.

5 - Lifting rod 85 is made in this case in the form of a pipe through which compressed air or gas flows into the ampoule. The end of the pipe has an elastic mouthpiece 25. which is adjacent to the edge of the ampoule. If the bar moves to the right (Fig. 6), the ampoule closes.

mouthpiece and covered with cheeks.

FIG. Figure 7 shows a device for clamping vials, having a holder 14, a protrusion 119 with a hole through which a pusher 18 passes, having a plate J20 at its lower end. The pusher 18 forms a guide for the auxiliary carrier 121. The protrusion 119 has a pin 122, on which two support rollers 15 and two clamping rollers 16 are rotatable.
