Lungs 11 and 13, a generally designated 15 sealing ring is arranged.

The Umrollungenll and 13 on the container 10 and on the lid 12 are ring 25 by a closure includes, the upper flange 26 from above around the roll 13 of the cover and the lower Flange 27 is placed around the roll 11 of the container 10 from below.

The locking ring 25, which is made of a band, strip or the like made of sheet metal or some other suitable material is made, is first given a shape in which its upper flange 26 of the shape 'the Umroilung 13 of the container lid 12 is adapted, while its lower flange 27 initially only ripened is, so that the locking ring 25 can be placed from above on the lid 12 and then on is deformed in a manner to be described later.

The locking ring 25 can be prematured with its upper flange, while its lower flange about its final shape from the start. The closing process to be explained later works then in front of you in reverse.

To the preformed closure ring 25, which is in the closed position around the folds of the container edge and the edge of the lid to press into the position of use, a device can be used which is described in detail below.

The device (FIG. 2) has a console (not shown) in connection with an upwardly extending arm which carries a housing generally designated 50 on a boom. The properties of the console to the top arm carries versteU bar a lower part generally designated 51 in which a is stored under the influence of a spring 53 de'r force stehende.Achse 52 in a bore which conically designed at its upper end at 54 is and with a press fit exchangeably receives a closure plate 56 provided with a hub 55 and a conical recess, on which a container 57 to be closed is arranged. The carrier 51 of the Verschließtellers 56 can be adjusted on the vertical arm of the Maschinengestclls in the vertical direction thus to be able to use the sealing machine for containers ver VARIOUS heights. In addition, the carrier 51 together with the closing plate 56 can be moved in the vertical direction by a certain amount in order to move a container 57 into a position in which the container engages the closing head and thereby triggers operations to be described later. ^: "■ '

- "Within the housing, bracket or the like, generally designated 50 and attached to the machine, for carrying the closing tools of the container, a bearing part 58 is used which is a carrier and support for a bevel gear , generally designated 59, the body part 60 of which is an appropriate one flange 61 formed integrally with it, which can rest on a bearing bush 62 inserted in the bushing 58. The bevel gear 59 is usually driven by means of a bevel gear from a drive motor (not shown) 59 carries a dog clutch piece 63, while a Klauerikupplungsgcgenstück 63 a on the upper side of a frontal displaceable in the vertical direction socket 64 is provided, which is mounted in an inserted into the socket bearing bush 65th

The. Bushing 64 carries wedges 65 which are inserted into slots 67 of a counter pressure generally designated 68

Haiters can intervene. The bushing 64 is fixed at its lower end to a further one, generally at 69 designated disk, in which a plurality of extending in the radial direction Slots 70 are formed. These slots accept laterally adjustable supports 71 of generally 72 designated closing tools. The supports 71 have threaded pins 73 at their upper end provided on which nuts 74 can be screwed. By loosening the nuts 74 and moving the Carrier 71 and thus the closing tools 72 can be used by the machine for containers of different diameters be adjusted. A compression spring 75 is provided between the disk 69 and the disk 68.

Inside the bush 64 and the body 60 of the bevel gear 59 is a generally designated 76, stored up to the top outside of the housing through axis, which at its upper end a cap 77 or the like. which rest on the upper wall of the housing part or bracket 50 can. The lower end of the axle 76 carries a sealing head plate 78, which is connected to an all-round Flange 79 is provided, which on its underside on the profiling of the lid edge of the container 57 or the locking ring 25 has a corresponding profile. This closing head plate 78 is with derrv Carrier 69 of the closing tools 72 connected by a ball bearing designated 80.

The carriers 71 are each provided with a slot 81 in which a closing tool, generally designated 72, is mounted pivotably about a horizontal axis 82. This locking tool carries a headed pin 84 in a bore 83 which is screwed in, and a locking roller 85 is rotatably mounted on the pin 84 and has a profile at 86 such that it forms a pre-matured locking ring.25 for the container. 57 (see above) in the final closed position. can press so that the side parts of the ring then wrap around the contours of the container roll and cling to them. Each closing tool 72 carries a cam 87 or the like on its rear side, on which a cam pin 88 can act, which is displaceably guided through a bore 89 passing through in the carrier 71 and fastened to the counterpressure holder 68. For this purpose, the counterpressure holder 68 is provided with a number of slots 90 corresponding to the number of closing tools; each pin 88 is adjustably fixed on the counterpressure holder 68 by nuts 91 and 92.

The arrangement of the cam pin 88 in the slots 90 and the locking tool carrier 71 in the Slots 70 are used to use the sealing machine for containers of different sizes. All that is required for this is, the nuts 91 and 92 of each cam rod 88 and the nuts 74 of the Closing tool carrier 71 to solve and they collectively sam along their slots 90 and 70 according to the To adjust the sizes of the locking headceller 78 or the cans and to determine them again. Such a machine works as follows: A can 57 is placed on the closing plate 56. set, which is provided with cover 12, locking ring 25 and, if necessary, with a seal (Fig. 1) and carries a sealing strip on its upper edge of the container. By the lever link (not shown) the carrier 51 of the closing plate 56 is moved upwards until the container lid moves from below against the sealing head plate 78. This position

is shown in FIG. With further upward movement of the named parts take on this' movement of the locking tool carrier 69 and the locking tools, the axis 76 and the bushing. 64 ■ part, the wedges 66 fastened in the socket 64 being able to slide in the slots 67 of the counter-pressure holder 68. This movement is continued until the claw coupling part 63a provided at the upper end of the bushing 64 engages with the coupling part 63 on the body 60 of the driven bevel gear 59 and the coupling connection is thereby established. From the same moment on, the parts 64, 68, 69 and the parts connected to them rotate as a result of the activated clutch. The counterpressure holder. 68, however, did not participate in the upward movement. As a result of the upward movement of the support disc 69, the bores 89 of the locking tool carriers 71 slide along the cam pin 88, and as a result the ends of the cam pin 88 press against the locking tools 72, and as a result of the relative movement between the parts 68 and 69, the locking tools 72 are pivoted about their axis 82 so that their ProfHrolle 85, 86 attack the lower, pre-matured parts of the locking ring '25 and bring these parts into the locked position obliquely from below, as explained above. After completion of this operation, the carrier 51 of the closing plate 56 is moved down again, the parts 64, 66, 69, 76, 78 with the associated parts move down again, so that the closing tools 72, which are stored outside their center of gravity , pivot themselves down again by gravity and the remaining parts assume the position shown in FIG. 2 again. Then the closed can is exchanged for a new can to be closed. The plate 56 and the capping head plate 78 must be replaced. A simplified embodiment of a machine similar to FIG. 2 is shown in FIG. 3, which basically works in the same way as the machine explained above, but with the difference that the locking jaws cannot be displaced in the radial direction. In this embodiment, a part 110 is provided which can be driven in any way and which can be driven, for example, in the same way as described with reference to FIG. This part carries a laterally protruding pin at its lower end in a reduced part III. 112, which cooperates with a slot 113 of a part 114 which can be moved up and down and which carries a sealing head plate generally designated 116 via ball bearings 115, for example. A lever 119, 120 is articulated on the part 110 at 117 and 118, which in turn is pivotably connected at the other end at 121, 121α to the carriers 122 and 123 of closing rollers, which in turn are connected at 124 and 125 ^ the part 114 are articulated and carry locking rollers 128 and 129 via screws 126 and 127. A can to be closed is designated by 130. The other parts can be designed according to the embodiment of FIG. By moving the can 130 to be closed with its closing head plate 116 upwards, the part 114 is also moved upwards, as a result of which the lever arms Ü9, Ϊ20 pivot the carriers 122 and 123 of the closing rollers about their pivot axes 124 and 125 via their pivot points 121 and 121a , whereby the closing process, as explained above, is then carried out. In this embodiment, the parts with the closing rollers can rotate continuously. The machine is designed so that at the same time as the upward movement of the can 130 to be closed, the part is coupled to its drive. This can also be done, for example, by using a pedal through which the can up against its. Closing head plate 116 is moved, driven by a mechanical, electrical or other control of the parts 110 and the parts cooperating with it. In both cases, the cans to be closed stand still while the closing means rotate around the can. PATENT CLAIMS: 1.
