Machine for sealing housing or container ends

The invention relates to a machine for closing the end of a housing, container, sack or the like. By pressing or Squeeze a clip around the end of the case.

Various container and housing sealing machines have recently become known. Almost all of these known machines use an upper and a lower plunger to close a closure member placed around the end of the container, e.g. B. a clamp to squeeze. The upper punch consists essentially of the lower shaped end of a driver, which takes the locking element (usually a clamp) from a feed chute or the like for the locking organs, and moves them into a position in which the locking element straddles the ruffled or crimped together.

collapsed end of the container . Danaoh will be the

The legs or prongs of the clamp are pressed by the driver against a stationary, likewise specially shaped lower stamp, whereby the legs or prongs are turned inward so that the end of the housing is completely encompassed and closed by the clamp.

In the known machines, this press ram combination has proven to be sufficient for certain size ranges of housings or containers. However, if, for example, a housing or a container with a size that is outside this specific size range is to be treated or closed, the amount of the housing or container volume becomes too large relative to the tree available in the actual clamping area, whereby there is the risk that parts of the housing or container wall are cut or destroyed by the clamp lugs or clamp prongs. If , in contrast, the housing has a size which is smaller than the size provided for the two rams, then a certain space can remain free when the clamp is pressed together, so that the container or the housing is only incompletely closed and there is a risk that the contents of the container flows out.

To avoid these disadvantages, spacer blocks have been developed I got used to it under the lower ram be pushed in order to enlarge or reduce the actual clamping area. The removal or use of such spacing blocks is, however, with time

Losses associated with the operator, and also nooh the efficiency of the machine due to such time losses is worsened. It has also happened that such spacing blocks are accidentally inserted into the product to be closed has fallen into it, which of course is not permitted.

In the known closure or Verklammerungsma is machines furthermore the cutting device for cutting off superfluous parts of the housing end by means of screws and bolts firmly inside placed on the machine so that if for any reason the knife is to be removed, a very extensive one Dismantling work is necessary to z. B. to replace a knife. The known machines are also stationary or otherwise inadequate curling or folding devices for crimping or folding the ends of the housing together used, in which the housing or the container is inserted into a narrow throat or constriction, the main Crimping or gathering work by the clamp is effected when this is done by the driver against or over the tapered housing end is moved. There is thus the risk that the housing or container wall by one or both Staple legs or prongs is pierced, which undiohten one Closure has the consequence. This disadvantage or this risk is based essentially on the fact that a lateral expansion or a spreading apart of the crimped or collapsed housing or container also in the area the legs or prongs of the closure member can be observed.

The invention has for its object to provide a machine of the type described, which does not match the above Is fraught with disadvantages. It is particularly a matter of providing an arrangement through which an adaptation to the most varied of housing or container sizes is possible.

To solve the problem on which the invention is based, a machine is proposed which, by combining the following Features is marked «

in contact with the lower punch 33.

The lower ram 33 is rotatably mounted on the shaft 34, which is movable in the bearing bore 35 of the side wall 13 and in the slot 42. The legs of the clip 19 fall onto this lower punch (which is located slightly below the entry opening or throat 22) to grip the crimped and compressed end of the housing before the clip is pressed around that end. The stamp surface 37 is mounted in such a way that it lies in line with the end of the stamp 18 of the IUi participant 17.

At the lower end of the raceway casing 21, an inwardly bent arm 29 is pivotally attached at one end at 33, while the other end of the arm 39 is pivotally attached at 4o to an arm 41 which can be reciprocated in the lateral direction. This arm 41 slides on a shoulder 76 of the stand 11 and is provided with the slot 42 through which the Yfelle 2 ^L 'isf "lower punch 33 protrudes, so that the arm 41 is able to be moved to and fro , since it encompasses the normally stationary 'loop 34 with its slot 4-2.

The arm 41 is rotatably attached to the crimping or switching device 45 by means of the slot 43 and the pivot point 44.

The curling device 45 is articulated to the stand 11 by means of the pivot 4o. A spring 47 which has one end at 48 on the lower part of the curling device 45 and at its other

End "at 49 attached to the stand 11, contributes to the

Return the curling device 45 to its outermost position, when the Gleitarn 41 is in its outward movement cycle is located. A pressure plate 5o is in the claw-like opening 8o between the wall 51 and 52 of the crimping device provided to the collapsed or ruffled Housing end 81 of housing 32 via surface 37 right before the actual clamping process.

Below the slide arm 41, a locking lever 54 is approximately in the vicinity its center at 53 is pivotally attached to the stand 11. The inner end of this locking lever 54 ends in an upwardly directed projection 55ι the end of which is shaped so that it can engage in the stenipelar surfaces of the stamp 33. That The outer free end of the locking lever 54 is at 56 at one end a spring 57, the other end 53 of which is attached to the stand. It can thus be seen that when the free The end of the locking lever 54 is pressed against the force of the spring 57 towards oban, the locking end of the locking lever 54 from the lower apprentice is released so that it is then possible Twist the 7 ^ eIIe 34 au by inserting a j'iinze into the base seat 5S the shaft 34 (Fig. 2 and 3) is inserted, and in this way to bring one of the ^ temple surfaces 37, 37 'etc. into position, namely the stem area that has the appropriate height for the housing to be closed or clamped. The I-Iehr- surface stamp 33 can be provided with stamp surface from those in a row; each stamp surface a few thousandths or

009817 / Ö949 BAD ORIGINAL

Hundreds of a millimeter higher than the previous punch surface, with the wall 52 of the crimping device a hole 35 can be provided through which a position mark (such as slotted arrow 59) can be observed on the lower punch. The individual position markings 6o for each lower punch or each punch surface can be attached to the side wall 52 so that a coin can be inserted (through the hole 35) into the slot 59 and the shaft 34 can rotate in order to correctly set the stamp surface 37 required for use.

On the back of the stand 11 there is a cranked or bent holder 61 for a motor 64. The holder ends in a vertical arm 62 which slides in a groove 63 which is cut into the knife motor 54. This motor is a common hydraulically or pneumatically operated motor : uii a Stciel CO, kii ua ~ da? -r.cfr. hi: .- and hurts wagüiide Lies aar 6 pounds is attached. The knife 66 slides in a notch 67 which is cut into the holder 61. If the rotor 64 is to be removed, it only needs to be lifted out of the holder so that the vertical locking arm 62 slides out of the groove. When this takes place, the pin 68 in the plunger 65 slides out of an upwardly open notch 69 of the knife, so that the motor is also released from the knife in this way. The! .Lesser is then removed by pulling it out along the ornamental 67.

A conventional clip channel 7o is provided to accommodate the Versohluß-2.anmerr-1i '* and through the Y / and 13 into the

A valve 71 is on the base plate ίο mounted to operate or operate motors 14 and 16 to control, whereby the necessary connections are available in order to operate the machine pressure medium via the lines 73 »74, 75 etc. to be fed to the motors. A pressure control device 72 is provided to enable a pressure to operate the valve 71.

A cover plate 36 is used to cover the machine elements, which would otherwise be exposed, fastened by means of screws inserted into holes 77 in the non-recessed edge of the stand 11 are used.

The puncture of the machine is as follows: In the rest position, the driver 7 is in the raised position, the knife 36 is retracted, and the crimping device 45 assumes its extreme position, as shown in! 1 is shown. When a housing or a casing is inserted into the inlet opening or throat 52 (as shown in FIG. 6) and the valve control member 72 is depressed, the plunger 16 pushes the driver 17 downward through the raceway casing 21 , while at the same time the arm 26 presses the track casing 21. The casing 21 also moves the arm 3bi outward, which in turn causes the G-guide arm 41 to move backwards.
