Of the present invention further developing can be learnt from following description and dependent claims.

The present invention will be described with reference to each one exemplary embodiment shown in each accompanying drawing below.

Fig. 1 is the schematic side view that is used to produce the device of the shoulder belt of supplying with the cigarette packaging station;

Fig. 2 is the front elevation of the part of device shown in Figure 1;

Fig. 3 is the planar view of this part of installing shown in Fig. 2;

Fig. 4 illustrates a planar view that is used for the shoulder belt of hinged cover cigarette box.

In the device shown in the figure, packing paper tape 1 all places (not shown) on the strip winding frame, wherein a packing paper tape 1 is supplied with more changing device 3 of paper tape continuously through roller 2, be fed forward and supply with the shoulder belt that has a pair of cooperation cutting roller 5 by other a pair of roller 4 and cut off station by installing 3, be cut into shoulder belt by cutting roller 5, then this shoulder belt sent to a multiple package position.Guide plate 6 is in packing paper tape 1 or shoulder belt between roller 2,4 and the cutting roller 5 in order to guiding.

Paper tape more changing device 3 comprises that has two the fixed type cutting knifes 7 of the oppositely-arranged cutting edge 8 of the back of the body mutually.Each of two cutting edges 8 all is used for according to shoulder belt in the shape at its leading edge or trailing edge place referring to Fig. 4 one of two packing paper tapes 1 being cut off.Cutting knife 7 is arranged in two formed acute angles of delivery track of packing paper tape 1, this delivery track converges in two gaps between the roller 4, disposes a sliver 9 that stretches to roller 4 and certain taper is arranged facing to a wafer cutting edge 8 of a packing paper tape 1.Side that deviates from fixed type cutting knife 7 at two delivery tracks by packing paper tape 1 all is provided with a movable cutting knife 10.Cutting knife 10 can enter cutting position with respect to fixed type cutting knife 7 by the piston 11 of a compressed air cylinder 12.

This paper tape more changing device 3 also comprise two be used for bridge joint the movable cutting knife 10 in the cooresponding outside and one on the throughput direction by the guide pillar adjusted 13 of the track between its resting guide 6.Each guide pillar 13 all can be adjusted, for example can adjust through an artificial actuating crank, so then this guide pillar just is rendered as position shown in the dotted line among Fig. 1, it can block the passage that packing paper tape 1 leads to cutting roller 5 in this position, and direct packets package material paper tape 1 enters drain tank 15.Usually, crank 14 is to utilize 17 lockings of a pin, and this pinning is engaged on carriage 16 and allows guide pillar 13 forward on the position that cutting roller 5 is carried.

Article one, packing paper tape 1 by paper tape more changing device 3 inwardly pass up to it and stretch out from cooresponding drain tank 15.The action of phase arthrotome 10 is that the action by associated cylinder 12 realizes, makes the front end of packing paper tape 1 be cut off and use the artificial removal whereby, meanwhile this this cut surplus packing paper tape and just have one corresponding to the shape of the front end of shoulder belt subsequently.At this moment packing paper tape 1 is to draw forward under mechanical control with a kind of like this method, and promptly the leading edge of paper tape does not just in time contact with the cutting knife that subsequently shoulder belt cuts off the cutting roller 5 of station.In transport process subsequently, shoulder belt cuts into predetermined length entirely, and is fed to multiple package position subsequently.Just first shoulder belt is a little short slightly, so cutting roller Qie Shiqie 5 first time can not cut off less than paper tape and to the narrow shoulder belt that might cause operational failure.

Second packing paper tape 1 also send to the same manner and by paper tape more changing device 3 then on request shape cut off, but it remains on this position till the first packing paper tape is almost used up.If the end that corresponding sensor sends the first packing paper tape 1 is near arriving signal, then the speed of equipment will be reduced to the velocity amplitude that requires in advance.After this end had arrived, the cutting knife that cuts the first packing paper tape 1 activated by an electronic control system, thereby made the first packing paper tape 1 accept the corresponding trailing edge of shoulder belt in its end.Paper tape more the upstream extremity of changing device 3 pulling force that spurs the first packing paper tape forward be interrupted, and the pulling force that spurs the second packing paper tape 1 forward is access in.At this moment the shaping initiating terminal of the shaping end of the first packing paper tape 1 and the second packing paper tape 1 is that operation enters shoulder belt cut-out station under the situation that has narrow gap each other.In the end of the second packing paper tape 1, running velocity correspondingly increases once more and switch step repeats.

The suitable distance of cutting off at the cutting edge of cutting knife 7,10 and shoulder belt between the cutting edge of cutting knife of station is that shoulder belt multiple of length on direction of transfer adds for example 1 millimeter of a little gap width, in order that be used for preventing that cutting off station at shoulder belt produces chip under the delay situation sending to forward be provided with in the handoff procedure.

As can be seen from Figures 2 and 3, movable cutting knife 10 can have guide pin bushing 18, and this guide pin bushing is suitable with guide rod 19, with their part arrangement be fixed on the carriage member 20 in case with the perpendicular direction of fixed cutting tool 7 on the movable cutting knife 10 of guiding.Bracket portion 20 is also supporting cylinder 12.In addition, be contained in spring 21 between two movable cutting knifes 10, this is led spring 21 and is used for cutting knife 10 is outwards applied prestress on opposing cylinder 12 action directions.Spring 21 is to be supported by the bar 22 that is fixed on the carriage member 20.
