Description

The The invention relates to a device according to the preamble of the protection claim 1. Devices of this kind are mainly used in sausage production used when it comes to the stuffed with meat Sausage casing to close by one of its end most Metallic, U-shaped closure clip is bent. The force for this bending process is from a stamp on one side and a die on the other side of the closing clip exercised on these.

at Devices according to the invention find a linear Stamp movement instead. This allows the drive of the Stamps with linear drives, for example pneumatic cylinders. The matrix also performs a movement to closing large sausage caliber to allow. The matrix will then moved up to the packaging, if this by other Medium has been brought to a small diameter, so that it can be grasped by the closing clip. In inventive Machines this movement takes place as a pivoting movement.

Previously known devices require massively designed pivot arms for the die movement (eg. DE 23 44 226 A1 . EP 0 030 755 A1 . EP 0 963 698 A1 . US 4,001,926 ). The consequent inertia is detrimental to energy consumption and speed. On top of that, the force for the bending process is partly also introduced via the shaft for the pivoting movement in the drive means therefor. The latter problem does not exist if the pivot axis for the die movement coincides with the punch line, ie the straight line along which the linear punch movement runs. But are just in previously known devices of this type ( DE-OS 1 511 754 ) particularly voluminous and therefore sluggish swivel arms required.

outgoing Of the latter prior art, the invention would like enable faster and energy-saving swivel movements. It solves this by the features of the characterizing part of the protection claim 1.

The Stamp start position is the position in which the linear movement starts. The die start position is the position in which the Pivoting movement begins. If stamp or die before or next their inventive linear or pivotal movement perform any other movements, leads this is not away from the invention, as long as for the mentioned movements according to the invention the condition of characterizing part of the protection claim is satisfied.

The Die pivot axis does not necessarily have to be mathematically exact Meaning lying on the straight line. It is enough that the Stamp, he would his linear motion over the Continue stamping position on the swivel bearing for would hit the die. This takes the pivot bearing the forces occurring during the bending process largely on. This causes the shaft over which the drive for the pivoting movement takes place, relieved. As far as the pivot bearing even comparatively massive must be carried out to to be able to absorb the force during the bending process acts this is not or not material to the inertia of the Device off.

Due to the features of the characterizing part of protection claim 1, the pivot bearing is compared to the embodiment according to DE-OS 1 511 754 (there 3 ) from the position above the punch to below. This allows a smaller radius for the pivoting movement and a much less massive version of the swivel arm for the die.

Preferably the die is arranged on a straight Matrizenarm. The matrix arm is pivotally mounted about the die pivot axis. Especially in this Meaning means that the direct connecting line between die and pivot axis of the Matrizenarm is taken, the force in Bending process so straight into the bearing of Matrizenschwenkarms is initiated. Incidentally, the boundary surfaces The Matrizenarms not be flat or cuboid. critical this is the direct line of force through the material of the matrix arm goes to the camp.

Further Preferably, the Matrizenarm of the die pivot axis in Tapered towards the die. This will do that for you reduces the pivoting torque required. The rejuvenation can be continuous or over one or more sections be distributed. In the latter cases, they have not rejuvenated extending portions preferably a constant cross-section.

Preferably the device has at least one channel arm for the die forms a stop in the die end position. One Kanalarm is characterized by having a section for forms the linear guide of the stamp. Further preferably there are two channel arms, the two stops for form the matrix of opposing sides. As a result, the die is stabilized. Unless the die is attached to a Matrizenarm is arranged, the channel arms come to this side to the plant. The channel arm is or the channel arms are preferably pivotable stored. The pivot axis (s) is / n preferably from the Die end position as seen on the side of the punch.

following is an embodiment of the invention with reference to drawings explained in more detail. Show it:

1 a side view of the inventive elements of a device according to the invention in an initial position of the movement;

2 the same view of the same elements in an end position of the movement.

A stamp 1 is arranged to perform a linear movement in the direction of the arrow S. Part of the guide channel is with 2 designated. This will be a closing clip 3 kept ready. On the back of the stamp meets 1 to take with it in its linear movement in the direction of the arrow S. For further guidance of stamp 1 and closing clip 3 swing two channel arms 4a and 4b in the direction of the arrows Ka and Kb together to form a guide channel for the further linear movement.

At the end of the linear movement, the closing clip hits a die 6 , which are at the end of a Matrizenarms 7 wel cher previously in the direction of arrow M about the die pivot axis 8th is pivoted, leaving the stamp 1 frontally on the die 6 meets and the closing clip 3 is bent in between. The die pivot axis 8th lies on the dashed line with the straight line 9 , The Matrizenarm takes the dashed line connecting line 10 between die 6 and die pivot axis 9 completely. Incidentally, it runs from the die pivot axis 9 to the matrix 6 slightly rejuvenated.

The channel arms 4a and 4b are from the die end position on the side of the punch 1 pivoted. They have end projections 11a . 11b on, with which the channel arms 4a . 4b from opposite sides of the die arm 7 come laterally to this for stabilization to the plant when the channel arms 4a . 4b in the position in which they form the guide for the stamp are pivoted.
