Definitions
- the invention relates to a method and an apparatus for manufacturing of packaging bags, envelopes and the like from web-shaped Material, the device including several stations includes a side folding station in which the material is processed including cut, provided with longitudinal and transverse pre-cuts, at least partially folded, provided with adhesive and is finally completed.
- the invention has for its object to provide measures to a material web with as little tension as possible through one or more To be able to perform processing stations of the device, so that especially changing roles does not have an adverse effect can.
- the invention provides that the web-shaped Material during processing in at least one of the different ones Stations transported on a moving surface and at the same time is held on the base with the help of negative pressure.
- the material web is preserved as long as possible and passes through as a coherent material web that is not yet in individual blanks is divided into one or more processing stations.
- a coherent material web that is not yet in individual blanks is divided into one or more processing stations.
- One or more belts essentially support the web large area, whereby suction air, which is created with the help of negative pressure below of the band or bands is generated, the web fixed in position.
- suction boxes located under the belts, which are connected to vacuum generators.
- the material as not yet cut material web with envelope windows is provided before the web is fed to the side folding station becomes.
- a pair of pull rollers belongs to a station 3 that is not of interest here 4, with the help of the sheet material 2 'through not shown stations arranged in front of station 3 in the transport direction is pulled.
- a station 5 connects to station 3 and can be used, for example, to create window openings 6 in the Material web 2 may be provided.
- a knife roller 7 is used directly for the production of the window openings 6.
- the transport of the material web 2 through the window gluing station 8 takes place with the aid of a suction belt transport device 10. It comprises at least one suction box 11 and one or more, side by side arranged conveyor belts 12.
- Each conveyor belt 12 runs around deflection rollers 12 ', so that there are no Upper run along a cover plate with suction openings of the suction box 11 moves.
- a suction box 11 can also several suction boxes arranged side by side and / or one behind the other his.
- a side folding station 13 connects to the station 8 in the production direction on.
- Cut side parts 14 and 15 continuously from a flat Position first up and then folded over. This is shown in FIG. 2 the dash-dotted outline of the edges 16 and 17 the material web 2 shown. According to the embodiment the edges 16 and 17 of the cut material web if necessary also overlap when folded.
- the side folding station 13 has to fold and fold up each Side part 14 or 15, a folding element 18 or 19 and a folding knife 20 and 21 respectively.
- the function and effect of the folding elements 18 and 19 and the folding knife 20 and 21 is basically known and therefore requires no further explanation.
- conveyor belts 12 are not only used for tension-free purposes Transport of material web 2 through the window gluing station 8, but they are also immediate according to the embodiment as a tension-free means of transport for the material web 2 in the Side folding station 13 is provided.
- the transport belts 12 are external transport belts 22 and 23 and around transport belts arranged between them 24, 25 and 26.
- the conveyor belts 22 to 26 together form one large-area, moving base 27 on which the material web 2 lies while it is being moved through the side folding station 13.
- the material web 2 is held on the base 27 or on the Transport belts 22 to 26 using vacuum 28 or suction air.
- the negative pressure (arrow 28) is generated with the aid of at least one, Suction box having suction openings 29 and at least one Vacuum generator 30. Also that to the window gluing station 8 belonging suction box 11 is via a line 31 to the vacuum generator 30 connected.
- the conveyor belts 22 to 26 run in the area the side folding station 13 around pulleys 33. You are with the Web speed driven and form together with the suction box 29 and the vacuum generator 30 a suction belt transport device 34.
- Suction belt transport device 34 of the side folding station a material web 2, the envelope window 9 '(Fig. 2) and optionally Has longitudinal and transverse breaks and laterally to form the Side parts 14, 15 of the envelopes are cut.
- the negative pressure prevailing in the suction box 29 is acted upon by Openings 35 in a cover plate 36 pull the material web 2 on the conveyor belts 22 to 26.
- the conveyor belts 22 to 26 are each spaced from each other so that slots 37 between them. The vacuum engages directly through these slots 37 on the material web 2.
- a single, sufficiently wide suction belt together with several if necessary Transport belts without suction function can be provided.
- suction openings 38 can also be located directly in one or more or be provided in all transport belts 22 to 26.
- the conveyor belts are conveniently on the toothed belt Cover plate 36 directed teeth. Through the teeth and also through the additional arrangement of the suction openings 38 is a uniform or targeted formation of the vacuum directly on the underside of the Material web 2 possible.
- the deflection rollers 33 for the transport belts 22 to 26 are arranged in such a way that the upper run 39 (Fig. 2 and 3) on the top 40 of the openings 35 or slots 29 having slots lies.
- FIG shown further station 50 In the transport direction behind the side folding station 13 is one in FIG shown further station 50, in which, for example, a separating cut with Can be generated with the aid of a cutting device 51.
- stations are used to complete the device 1.
- the invention is not based on that described and in the figures shown features limited. Rather, there are also variations possible without the basic inventive idea to deviate.
- a suction belt transport device whose conveyor belts 22 to 26 are not only arranged at a distance from one another are and thereby form slots 37, but also additionally Have suction openings 38.
- the deflection rollers 33 can also external conveyor belts and / or those on the inside Transport belts are located in different places.
