Abstract
A tube holder for a tube-filling machine has a cup-shaped housing, which has an upwardly opening tube mount, into which a tube can be inserted with an axial end area thereof. A clamping device, by which a clamping force can be applied to the tube, is arranged in the area of the tube wall of the tube mount. Provisions are made for the clamping device to have at least one inflatable clamping element with an inner chamber, into which a pressurized fluid can be filled through a feed line. The clamping element can be adjusted between a clamping position, in which a clamping force is applied to the tube, and a releasing position, in which no clamping force is preferably applied to the tube.
Claims7
A tube holder for a tube-filling machine, the tube holder comprising:
- a cup-shaped housing, which has an upwardly opening tube mount with an inner wall, into which tube mount an axial end area of a tube can be inserted, the inner wall of the tube mount defines at least one recess configured as a circular ring groove;
- a clamping device by means of which a clamping force can be applied to the tube, the clamping device being arranged in an area of the inner wall of the tube mount, the clamping device comprising a feed line and at least one inflatable clamping element with an inner chamber, into which a fluid can be filled under pressure via the feed line, whereby the clamping element can be adjusted between a clamping position, in which a clamping force is applied to the tube, and a releasing position, the clamping element having a ring-shaped hollow configuration and the inner chamber being a ring chamber, the clamping element being arranged in the ring groove;
- a base part, wherein the housing is detachably connectable with the base part;
- and
- a coupling device arranged in the feed line between the housing and the base part for coupling a portion of the feed line associated with the housing to a portion of the feed line associated with the base part, the coupling being configured to automatically have the portion of the feed line in the base part communicate with the portion of the feed line in the housing when the housing is connected to the base part,
- wherein the coupling device includes a nonreturn valve configured to open automatically when the housing is placed on the base part.
