Definitions

the present invention relates to a method for adjusting the transverse sealing and separating position in the case of endless tubular bag packs according to the preamble of independent claim 1 and to an apparatus for carrying out the method according to claim 9.
tubular bag packs as described, for example, in CH-A 527 090, a film web is drawn through a folding box in order to form a tube from this film web.
the items to be packaged are fed continuously to this tube at regular intervals.
the filled tube is then divided into individual packs by transverse sealing seams and mostly the packs are separated at the same time as the sealing. According to this publication, up to about 300-400 packs per minute can be produced in this way.
the film web is printed, it must of course be ensured that the motifs are always arranged the same.
the lengths can change greatly as a result of fluctuations in the tensile stress, so that an exact setting of the sealing and separating position is necessary.
the object of the invention is to continuously correct an incorrect position of the marks with respect to a cutting point.
the device for performing the method is characterized in claim 9.
triangular-closed arrows when filled, mean the material flow, and when they are empty, the energy flow, open arrows, on the other hand, mean the information flow.
the energy is fed in at N.
tubular bag packing part A a tubular bag transport part B, an optoelectric sensor C and a transverse sealing and separating part D as well as a main drive E, a second drive H, a computer R and an input and display part J are shown schematically from a tubular bag packaging machine.
the machine status MC namely "stands still” - “runs” - manual drive "-” machine stop "in addition to the freely selectable parameters from the input and display part J, in addition to the data on the angular position Fi of the film pattern Z and the marks M (Fig. 2) and those Entered via the angular position Ms of the hose P and via the speed nMi of the machine, the letters i, s behind the device designation indicating whether it is an actual value or a setpoint.
the second drive H receives information about the required speed nFs from the computer R. Electrical energy flows from the two feed points N shown separately into the drives E, H, which is transmitted as mechanical energy with a main shaft, tubular bag packing part A and to the transverse sealing and separating part D.
the transport part B is directly controlled by the second drive H and the speed is independently kept constant.
a disc rotor motor can be used as the drive machine for the second drive.
the information about the angular position ⁇ Mi is represented by 360 pulses per revolution of the shaft. These can be generated by means of an angle encoder, by means of a step pulse generator or also using an inductive pulse generator.
Tachometers can be used to output the speed information nMi and nFi.
a potentiometer for emitting an adjustable constant voltage can be provided for the input of the speed of the machine nMs.
the mode of operation is described with reference to FIG. 2.
a tubular bag band P which is to move from right to left.
the optoelectric sensor C and the transverse sealing and separating part D of the machine are shown.
the marks M and the motifs or figures F are indicated on the tubular bag band P.
the first line shows the pulses ⁇ Ms from the cross seal and separating part D, which have a variable distance here.
the pulses ⁇ Fi in the second line are the pulses from the sensor C and coincide with the marks M in time.
