In Figures 1 and 2 is a conveyor 1 for containers 2 (see Fig.3), the inlet station 3, a Magazinstation 4 and a closing station 5 includes. First a container 2 is sloping slightly obliquely arranged roller conveyor 6 is introduced into the inlet station 3, in which the container 2 provided by both sides pliers-like drivers 7 is detected for further transport. The respectively opposite arranged pliers-like carrier. 7 are controlled synchronously via pneumatic cylinders (not shown), due to the tong-like design of the driver 7 containers of 2 different diameters with the Conveyor 1 can be transported. Of course However, for the transport of the container 2, other Conveying devices, such as conveyor rollers, hinges, Pawl or chain conveyor or the like, provided become.

With the help of the driver 7, the both sides each on one common rail 8 are mounted, which also has a pneumatic drive (not shown) synchronously in or against 9 are moved, the container 2 of the Inlet station 3 transferred to the magazine station 4. Here is with the help of a magazine station 4, preferably according to the in AT 5904 U disclosed cover magazine is formed, whose Content regarding the lidded magazine by reference as here is considered included. In this magazine station 4 will a lid / clamping ring unit 10 consisting of a lid 11th and a closed clamping ring 12 on an upper container opening placed with a flange 13 (see Fig.3).

Subsequently, the container 2 with the launched Lid / clamping ring unit 10 with the help of the driver 7 in the Closing station 5 transported further, and at the same time another Container 2 from the inlet station 3 in the magazine station 4 promoted. The previously located in the closing station 5 container 2 is synchronously over a slightly oblique sloping arranged roller conveyor 6 'further transported.

3, the closing station 5 with a device 15th for closing the bucket-shaped container 2 with a lid 11 (see Fig.4) by tensioning a clamping ring 12 with a Tension lever 16 having clamping ring closure 17 in detail visible.

In essence, the device 15 is composed of a Overhead frame 18 with a clamping unit 19 with a pivotally mounted actuating or pivot lever 20 with an engaging member 21 for a positive connection with the tensioning lever 16 and a lifting / rotating device 22 with a Turntable 23 together, over which the container starting from a transport position, in an alignment position, an open position and a closed position can be lifted. If the device 15, in particular the overhead frame 18, formed symmetrically, the device may vary depending on Request from both sides with a container 2 to be fed. Furthermore, the modular design of the individual components (Conveyor 1, lifting / rotating device 22, etc.) favorable, as a flexible adaptation of the specific arrangement to the respective spatial conditions is possible.

As can be seen in particular from FIGS. 3 and 4 the actuating lever 20 about a pivot axis 20 'in the overhead frame 18 pivotally mounted. For this purpose is a pneumatic cylinder 25 is provided which is pivotally mounted about an axis 26. Of course, for the pivoting movement of the actuating lever 20 but also any other drive device, in particular, for example, a rack drive, provided his.

As can be seen in particular from Figure 5, the engaging part 21 of the pivot lever 20 on a carriage 27 pivotally stored so that some freedom of movement between the Engagement part 21 and the pivot lever 20 is ensured. Of the Carriage 27 is in a groove 28 of the actuating lever 20 in whose longitudinal direction is displaceably mounted, wherein for its control, a pneumatic cylinder 29 is provided. The engaging member 21 has a receiving opening 30, which of two, each having an undercut strips 31 formed so that the cantilevered end of a clamping lever 16 of the clamping ring closure 17 by longitudinal displacement of the Slider 27 can be inserted into the receiving opening 31.

In Figure 6, the turntable 23 is the lifting / rotating device 22nd seen in detail, wherein the turntable 23 for vertical displacement is connected to an intermediate plate 32, the over two guide rods 33 in openings of a bottom plate 34th is mounted vertically displaceable. For rotation of the turntable 23, a rotary motor 35 is provided which is one with the turntable 23 connected shaft 36 drives. At the bottom of the rotary motor 35, a roller 37 is fixed, which is for vertical displacement of the turntable 23 on a cam-like ramp ramp 38th runs up (see Fig.7). To strongly different heights of the containers To compensate 2, the shaft 36 with the role 37 spring-mounted. Alternatively, however, can also the upper Plate of the overhead frame 18 to be resiliently mounted.

In Figure 7, the hub-rotating device 22 is in a opposite 3 shifted position shown, in which the turntable 23 in another of three different vertical positions of Ramp 38 is shifted. For vertical displacement of the turntable 23 is the ramp 30, on which the roller 37 accumulates, with three horizontal sections 39, 40, 41 provided so that by moving the ramp 30 of the Turntable 23, starting from the transport position in three different Vertical positions (alignment position, opening position, Closed position) can be moved. To the shift the ramp 30 in the direction of arrow 38 'is a pneumatic cylinder 43 provided (see Fig.2).

The first horizontal section 39 of the ramp ramp 38 corresponds to the alignment position shown in Figure 3, in which the container 2, starting from the transport position shown in Figure 2 is lifted and in which the container 2 with the launched Cover / clamping ring unit 10 is turned until until the clamping ring closure 17 of the clamping ring 12 sprung over a mounted stop 44 which actuates a sensor is detected (see Fig.8). When moving the ramp 30 in the direction of arrow 38 'comes the roll 37 in the second horizontal section 40, so that the turntable 23 with the container 2 and the lid / clamping ring unit 10 in the open position is lifted, which is shown in Fig.7. Instead of the shown linear ramp 30 can also be a circular curved Be provided ramp. The advantage here is that a circular curved ramp only in a single (Turning) direction must be moved, and the transition from the uppermost position (shown in FIG. 11) to that shown in FIG Transport position directly - without support on the intermediate stages - can be done.

After alignment of the clamping ring 12 at the level of the subsection 39 and opening the clamping ring 12 at the level of the subsection 40, the run-up ramp 38 continues in the direction of arrow 21 shifted so that the roll 37 in a third horizontal Part 41 comes to rest, in which the turntable 23rd is present in a top closed position, in which the lid 13 with the aid of a displaceably mounted against a spring force Centering and hold-down plate 45 (see also Fig.3 and Fig.11) is pressed into the upper container opening, and the Clamping ring 12 reliably on the flange 13 at the upper edge of the container is pushed.

In Figures 8 to 10, the turntable 23 is in the alignment position shown in Fig.7, in which the roller 37 rests on the portion 40 of the ramp 38. In this Alignment is the container 2 together with the lid 13 and closed Clamping ring 12 first as long with the help of the turntable 23 turned until the stop 44 a connecting leg 46 of the trained as a toggle clamping ring closure 17th detected with a clamping lever 16.

Once the closed clamping ring 12 and the lid / clamping ring unit 10 is present in the predetermined position (see. 8), the actuating lever 20 by means of activation of the Pneumatic cylinder 25 in the one shown in Figure 9 an engagement position pivoted. Subsequently, the engaging part 21 by activation of the pneumatic cylinder 29 with the cantilevered End of the clamping lever 16 brought into connection.

After a positive connection between the engaging part 21 and the tensioning lever 16 has been produced, wherein the Engaging part 21 in its receiving opening 30 a stop (not shown) to the insertion depth of the clamping lever 16 in the receiving opening 30 to specify exactly pivots the actuating lever 20 in its open position, which is identical to the original waiting position.

As can be seen in particular from Fig.10, falls Pivot axis 20 'of the pivot lever 20 substantially with a Pivot axis 17 'designed as a toggle joint between the tensioning lever 16 and the connecting leg 46 of the Clamp 17 together, so when opening the Spannringverschlusses 17 lowest possible wear forces the clamping ring closure 17 act. Additional forces for expansion the circumference of the clamping ring 12 when opening the clamping ring closure 17 are not required.

In Figure 11, the turntable 23 is then in its uppermost Closed position shown in which the roller 37 on the section 41 of the ramp 38 rests. In this closed position is the turntable 23 and the container 2 after opening the clamping ring closure 17 transferred to the clamping ring 12 reliably to push over the flange 13 of the container 2 and the lid 11 in the upper container opening by means of the centering or hold-down plate 45 press.

To the clamping ring 12 after opening the clamping ring closure 17 to hold reliably in its horizontal position is the clamping ring 12 at the level of the alignment or open position Surrounded by a retaining ring 48 peripherally, in the Essentially closed about 270 °, and a slight larger diameter than the closed clamping ring 12, so that the clamping ring 12 in its opened and thus circumferentially larger open position in the retaining ring 48 frictionally is held.

As can be seen in Figure 12, the actuating lever 20 after the pressing of the lid 13 in the container opening in his Engaged back position pivots, causing the clamping ring closure 17 is closed and thus the container 2 with the lid 13 is connected.

For releasing the positive connection between the engagement part 21 and the tensioning lever 16, the carriage 27, on the engaging member 21 is pivotally mounted, via the pneumatic cylinder 29 shifted away from the free end of the clamping lever 16.

After releasing the positive connection, the operating lever 20 then in his stand-by position shown in Figure 3 moved back in which he remains until over the stop 44 with a aligned in the predetermined position lid a closed clamping ring is detected. At the same time the Turntable 23 in its lowest support or transport position postponed.

Of course, instead of the displaceably stored Engaging part 21 any other form-fitting Connection between the clamping lever 16 and the actuating or Swivel lever 20 can be selected as well as various drives for Pivoting the actuating or pivoting lever 20 instead of the Pneumatic cylinder 25, for example a rack drive, be provided, it is only essential that exclusively by the positive connection between the actuating lever and clamping lever in a simple way opening or closing the Clamping ring closure in the manner of a manual operation is possible. Of course, the device is by no means on the use of containers of a certain size or a certain diameter limited, but they can for containers of different sizes or different Diameter can be used or on different containers to be converted. Likewise, the device is not on clamping rings with a certain opening or closing direction limited, so that in particular the entire device for Opening or closing of clamping ring locks, which in opposite Direction to the illustrated clamping ring locks to open or close are designed mirror-image can be.

In Fig. 13 (see also Fig. 3, 7 and 11) is a splint device 50 for inserting a split pin 51 into an opening 16 ' the clamping lever 16 shown in detail on the overhead frame 18 is attached so that the entire closing process together the introduction of a pin 51 to secure the closed position the clamping lever 16 can be performed automatically.

In this case, the splint device 50 has a feed device 52 with a pneumatic cylinder 53, the piston 54 with a feed part 55 is connected. In the feed part 55 is an engaging member 56 is received, this against the force a coil spring 57 in the feed part 55 perpendicular to the feed direction 58 of a plurality of split pins 51 comprehensive sapwood 59 is slidably mounted.

The engaging member 56 in this case has a zweingrig trained Engagement section 60, which is for advancing the split pin 59 positively with a T-shaped end 61 of a Splints 51 comes into engagement. Due to the positive connection between the fork-shaped engagement portion 60 and the T-shaped end portion 61 of a split pin 51 is when extending the Piston 54 of the pneumatic cylinder 53, the pin belt 59 in the feed direction 58 taken and thus the first split pin 51 of the Split pin 59 (previously separated from split pin 59) in FIG the opening 16 'of the clamping lever 16 is inserted.

At the retraction of the piston 54 of the pneumatic cylinder 53 in the retracted position shown in Figures 15 and 16 the pneumatic cylinder 53 does not take the sapwood 59, the engagement portion 60 is on its one engaging surface 62 opposite side 63 on a chamfer, so that on retraction of the piston 54 in its retracted position the engagement member 56 is displaced back against the force of the spring 57 is and the sapwood 59 is not taken.

To guide the split pin 59 in the device 50 is a between two strips 64 'arranged feed or guide channel 64 provided in which the sapwood 59 with the help of Feed device 52 is moved in the feed direction 58.

For separating a split pin 51 from the split pin 59, on which a plurality of pins 51 directly adjacent to each other are arranged, a cutting device 65 with a cutting blade 66 which is transverse to the feed direction 58 in a stationary bearing member 67 in the cutting direction 68 überschieblich is stored and in a slotted guide 69 of the feed part 55 is recorded.

In the extended shown in Figures 13 and 14 Position of the piston 54 of the pneumatic cylinder 53 is the Cutting knife 66 of the cutting device 65 in its retracted arranged spaced from the sapwood 59 position. At the Returning the piston 54 from its in FIGS. 13 and 14 shown extended position in the shown in Figures 15 and 16 shown retracted position remains the cutting blade 66, while a cutting blade holder 70 by means of the bolt 70 ' in the feed direction 58 arranged parallel link channel 69 ', as shown in FIGS. 13 and 14 spaced from the sapwood 59 position. Only in the direction of feed 58 obliquely slotted gate channel 69 "is the Cutting knife 66 in the cutting direction 68 perpendicular to the longitudinal direction the sapwood belt 59 shifted so that a Split pin 51 is separated from the split pin 59 and thus this Pin 51 subsequent to leaving the guide channel 64 of the Pin device 50 inserted into the opening 16 'of the clamping lever 16 can be.

To an unwanted lifting the pin belt 59 from the guide channel 64 of the splint device 50 during the cutting process Reliable to avoid is the cutting blade 66th arranged opposite a counter or bearing plate 74, which is positioned slightly above the cutting blade 66.

Starting from the retracted shown in Figures 15 and 16 Position of the piston 54 of the pneumatic cylinder 53 results Thus, that the engaging member 55 when driving over in the extended position shown in FIGS. 13 and 14 Piston 54 of the pneumatic cylinder 53 per operation or stroke first a so-called.
