The invention relates to a plug driving device in the preamble of Pstenta. , Spruchs 1 mentioned Art.

In the known from DE-OS 15 32 505 plug driving device of this type, the plugs are over a horizontal conveyor channel inserted directly into cells of a rotating platform carrying driving heads, with a suction attachment at the lower end of the driving ram to prevent the Stopper is provided. In this device, however, the reliability of the stopper feed still allows to be desired. In addition, if there are gaps in the supply of the containers to be closed, those for them will fall certain plugs on the corresponding sections of the turntable, which can lead to malfunctions and damage.

From US-PS 21 80 836 a sealing machine is also known in which the stopper each over an inclined channel-like magazine slide directly into an edge recess of a turntable carrying the driving heads. Two to support the outer flange of the plug below the edge recess Pivotably arranged fingers are lifted over during the driving process by the bottle neck Cams pushed apart to release the plug. However, this construction is prone to failure due to jamming of individual plugs.

The object of the invention is now to provide a plug driving device of the type defined in the preamble of claim 1, which with simple Aids one even if there are gaps in the container supply

From the Oiopfen-ZüfuhrvGnichiüng 4 plugs 29 of a certain shape are constantly fed to the plug driving unit 2 in an aligned manner. As FIGS. 7, 8 and 12 show, the stoppers 29 each have, below or above a collar 29/4, an insertion section 290 for insertion into an opening provided in the top of the container and an upwardly protruding section 29C which in the F i g. 4 to 8 and 11 shown stopper feed device 4 comprises a storage container 47, a dispensing device 48, a plug aligning device 49 and a guide device 50. By means of the dispensing device 48 by means of a vibrator 4SA from the unordered supply in the storage container 47 stoppers 29 of the The type shown, supplied in suitable quantities to the stopper alignment device 49 and moved therein by vibration in the circumferential direction, aligned during their movement and then in the aligned state in tangential to the movement path 49L (see FIG. 4) of the alignment device 49 in the guide device 50 introduced which has a sloping sliding channel 52. As shown in Figs. As shown in FIGS. 5 and 11, the slide channel 52 has at its lower portion a linear conveyor 53 which is designed so that the plugs 29 are conveyed to the front end of the slide channel 52 by the vibration. On both side walls of the plug 29 leading sliding channel 52 channel-like rails 54 for guiding the collar 29/4 are of the stopper 29 is formed The front end portion of the sliding channel 52 of the rotary path (stopper receiving sheet L 4) is bent along the hook portion 27Λ and provided with a cover plate 55 . A curved spring 56 is provided on the curved portion of the slide channel 52 to receive the foremost of the plugs 29 being fed in alignment. A projecting leaf spring 57 is attached to the cover plate 55

The stopper feed controller 51 is adjacent to the stopper feeder 4 and the transfer unit 3B across the space between them (see FIG. 1). As the F i g. 9 and 10 show is on the 35 side facing a sensing lever 60 mounted to the transfer unit, while on the side of the plug supplying apparatus 4, a Blokkierungsarm 61 with a Stopfenanpreßsitz 61Λ is The sensing lever 60 is arranged so that it, the container-guide path L 3 of the Facing the transfer unit 38 and is connected via a vertical shaft 62 to a swing arm 63 pivotally mounted thereon. The feeler lever 60 is rotatable about the vertical shaft 62. The blocking arm 61 is connected to a vertical lever 65 via a horizontal shaft 64. A retractable push rod 66 is connected by a coupling 67 to a connecting rod 68 which extends from the pivot arm 63 through the lower end of the vertical lever 65. The push rod 66 and the connecting rod 68 represent a transmission shaft. The vertical lever 65 is gripped between a stop 69 and a spring seat 70 of the push rod 66.

Furthermore, one is on the spring seat 70 pressing spring 71 and one is the stopper press seat 61/1 down

The sensing lever 60 in turn is arranged at such a point that it detects the presence of a container V on the receiving section 11 into which the stopper 296 is driven, "! Rs fclsendc" becomes the mode of operation of the StQ ⁿ fcn-Ein driving device with reference to the F i g. 12 and ! 4 explained further. The stopper driving device 2 has its reference position (angle of rotation 0 °) set Starting position (see Fig. 1). When the plug driving device 2 rotates clockwise by 90 ° counter- rotates about this reference position, a vessel V is completely transferred from the transfer unit 31 B on the receiving portion 11 of the rotary table 10 therefore has to de / sensing lever 51 is arranged to be 60, the plug-supply control to a position in a clockwise is 90 "away from the container transfer point on the container guide track Lj. A plug 29 is fed onto the plug receiving track I ₄ in a position which is 5 ° from the reference position (see FIG. 9).

If the rotary shaft 5 continues to rotate together with the filling unit 1, the turntable 10, the Positioning device 17, the stopper receiving device 24 and the driving head 30 rotated with it. In the The reference position are the centering head 20 and the Ein drive head 30 at the upper end of their trajectory (upper waiting position) while the hook portion 27a is in its fully extended position. When the hook portion 27a rotates 5 °, he begins by the bent spring 56 at the front Ren end of the sliding channel 52 held foremost stopper 29 to receive. This recording ends when the rotation exceeds 5 ° (see FIG. 12a). With the further rotation of the hook section 27A , the plug 29 is forcibly pulled off by the spring 56 gene and brought from the curved portion of the slide channel 52 in the plug receiving path U while it is held in the hook portion 27Λ. The leaf spring 57 comes into resilient contact with the top of the stopper 29, so that the stopper 29 continues to be rather, it is held in the hook portion 27A . When the angle of rotation has reached approximately 25 °, the centering head 20 begins to move downwards and, after the described transfer of the container purchase, reaches the receiving section 11 of the turntable 10 in one rotation position of 103 ° the lower end of its path of movement in order to position the container V. At this point in time, the centering head 20 is pressed elastically against the container V due to the restoring force of the spring 23. Meanwhile at 35 ° the inward

27 A held plug 29 (see Fig. 12b). At this point, the stop flange 30A of the driving head 30 engages the top of the centering head 20, preventing the driving head from dropping below the center position. The pneumatic pressure medium cylinder 33 is at a low operating pressure at this point in time. Immediately thereafter, the valve 42, 4 is switched to begin suction, so that the plug V ^ is sucked onto the driving head 30. The suction is maintained until shortly after the start of driving (angle of rotation 130 °). When an angle of rotation of 60 ° is reached, the driving head holding the plug 29 begins to move upwards. During the further rotation (at 64 "), the hook section 27/4 is withdrawn from its position under the driving head 30 to the rotary shaft S (see FIG. 12c). After the container V has been positioned by the centering head 20, the driving head 30 begins with the second stage of its downward movement and at about 250 ° the entry

At the end of the driving, the driving head 30 remains in the lower end position of its second downward movement. After driving in, the driving head 30 is moved up into its upper waiting position, where it remains until the next stopper suction begins. After the driving head 30 has moved upward, the centering head 20 is moved into its upper position and the container is released from one position. Immediately thereafter, the container Küber is discharged along the discharge path Ln ₁ , whereby an operating cycle is ended which is then repeated in the same way.

If a container V is missing from the transfer unit 3B in the workflow described, this is detected by the feeler lever 60 (see the dashed line in FIG. 9). The second stopper 296 is then pressed against the sliding channel 52 by pivoting the blocking arm 61 down around the horizontal shaft 64, which prevents the feeding of the stopper 296. This lock is released when the sensing lever 60 detects the presence of a container V. This control prevents useless feeding of plugs 29.
