Definitions

  • the invention relates to a bottoming device for paper sacks according to the preamble of claim 1.
  • sacks include, for example, the so-called valve sacks, into which valve sheets are generally inserted when the floors are being produced.
  • the floors themselves are often equipped as cross bottoms, as shown for example in DE 090 145 48 U1 and DE 3020043 A1.
  • parts of the floors are glued to one another and / or with the valve leaflets with the aid of glue.
  • a floor laying device is known for example from DE 1 226 869 B.
  • either the areas of the bottom folds to be bonded or the strips associated with them, that is to say all areas to be bonded together, are provided with a glue application and then glued together by means of combination or folding
  • a size-appropriate application of glue is usually carried out by bringing a mounted on a rotating roller format part in a turn of the roller with a glue roller or other Leim arrived- or transfer parts in contact and thereby applied with glue.
  • the format plate transfers the glue stored on it to the respectively to be bonded areas of the later bag bottoms or the slip.
  • the format part is provided with characteristic elevations, which are adapted to a specific sack format.
  • the format parts are exchanged.
  • This type of glue application has proven itself, since so large quantities of the difficult-to-handle starch glue can be applied cleanly and in the right format.
  • size-appropriate glue application this is an order form tailored to the type and format of the bag. The order within this order form is usually flat, often the edges of the mold is of particular importance for the durability and tightness of the bags.
  • US 4 157 149 proposes a glue application apparatus for packaging materials comprising a nozzle plate having glue valves disposed thereon.
  • the glue that is supplied to the glue valves can be applied directly in the desired format on the workpieces to be glued, without format rolls or format parts are needed.
  • the valves are integrated in a gun.
  • the application head also has a bore through which at least a portion of the valves can be acted upon with glue.
  • the object of the invention is to further develop the bottom-laying device in such a way that it is possible to dispense with a format roller or format parts and still permit a format-appropriate application of the glue, wherein the glue is to be distributed uniformly over the surface to be glued.
  • the applicator head can be provided with an application plate, into which the said glue outlet openings, which can be acted upon by valves selectively with glue, are introduced.
  • the glue is exposed to a pressure that is greater than the ambient pressure.
  • the supply of the valves with glue is initially via glue supply lines, which supplies the glue to a chamber.
  • the valves are in contact with this chamber. With a diameter of m mm, it is ensured that the very viscous glue, usually starch glue, can flow through the chamber without getting stuck.
  • the glue supply is, however, realized by a through the applicator head through tube so that the glue can get into the cavity of the applicator head, the tube has holes or openings in the region of the applicator head.
  • the applicator head can also be slidably provided on the tube.
  • the chamber may have a circular cross section.
  • the cross section may also differ from a circular shape, while the Cross section but dimensioned so that a circle with a diameter of 5 mm can be inscribed, so that a continuous glue flow is ensured to all valves.
  • the chamber has a diameter of at least 7 mm. Only at this diameter is achieved that prevails at all valves substantially the same glue pressure. When falling below this diameter, it is possible that in the flow direction of the glue, the rear valves are acted upon only with a low glue pressure, so that also caused by these valves glue traces may be too thin.
  • the chamber has a diameter of at least 10 mm. This diameter is to be provided above all when the valves are arranged with a high density.
  • the chamber is arranged in or directly on the application head in order to keep the distance between the chamber and the valves small. If the glue, which can be very viscous as described above, pressurized, the pressure is at short connections from the chamber to the valve without significant pressure losses at the valve. As a rule, this connection has a length of a few millimeters.
  • valves in the spatial direction (y) transversely to the conveying direction (x) of the bag components overlapping.
  • the valves are supplied with glue from the same chamber. This makes it possible to obtain a greater density of valves in the spatial direction (y) and thus a greater density independently of one another as well as switchable glue traces.
  • Such an arrangement of the valves comprises in particular a two- or multi-row arrangement, wherein the rows in the spatial direction (y) and in the conveying direction (x) of the bag components are spaced apart.
  • the spatial direction (y) means that spatial direction which is transverse to the conveying direction (x) the sack components runs, but in the plane defined by the sack components, the third spatial direction, which is transverse to the conveying direction (x) of the sack components but also transversely to the sack component layer, is within the scope of the present invention not matter.
  • the volume of the chamber to the volume sum of all glue connections to and from the valves, which are supplied from this chamber with glue, at least a ratio of 1.5 has. Only from this factor, by which the volume of the chamber is greater than the sum of the glue lines, at all valves of the pressure prevailing in the chamber at all valves without significant pressure losses. This ensures that with open valves and at all glue outlet openings, which are supplied via the chamber with glue, the glue with substantially the same pressure is pushed out.
  • the at least one chamber is introduced into the application head bore.
  • On both end faces of the gun can be provided with a first holes through which the glue is supplied to the cavity, and a second bore through which the glue is removed again.
  • the cross-sectional areas of these inlet and outlet bores are smaller than the cross section of the chamber.
  • the cross section of the chamber is 40 mm 2 larger than the cross section of the glue supply lines.
  • Fig. 1 shows a gun 1, as it is used in a Beleimungsstation in Bodenlegevorraum invention.
  • This application head 1 is composed of a job plate 2, to which valves 3 are attached.
  • the glue is supplied to the application head 1 via the glue line 4a.
  • the glue passes beyond glue line 4b out of the application head.
  • the gluing station are fed in the direction x unprimed labels 5.
  • Each valve 3 is associated with one or a group of Leimaustrittsöfmungen in the non-glued sheets 5 facing side of the application plate 2.
  • the glue flow to the glue outlet opening can be made or interrupted by the associated valve 3. In this way, it is possible to apply 5 different glue tracks on the unprimed label, which run parallel to the conveying direction x of the unprimed label 5.
  • a regularly interrupted glue trace 5 can be applied.
  • Also can be produced are short traces of glue T, interrupted traces of glue 8 and continuous glue traces 9. If there is no unprimed note 5 under the gun 1, the glue flow is interrupted by all valves 3, so as not to unnecessarily pollute the gluing station.
  • the application head 1 can likewise be displaced in this direction.
  • described applicator head can not only be used for gluing of slips, but is due to a variability of the producible glue marks also suitable for applying glue to the areas to be bonded to the subsequent sack bottom.
  • FIG. 2 shows a linear arrangement of a plurality of applicator heads 1, which are arranged along the tube 10 in the direction y transversely to the conveying direction x.
  • the tube 10 can also serve as a guide rail, along which the individual applicator heads 1 can be displaced relative to each other.
  • rows of valves 3 are mounted on the applicator heads 1 on the applicator heads 1 .
  • Fig. 3 shows an end view of an applicator head 1 according to the section III-III of Fig. 2.
  • the applicator head 1 is provided with two parallel rows of valves 3, wherein the valves 3 may be arranged offset in the non-visible direction y ,
  • glue compounds 11 are introduced into the application head 1 to the valves 3, which begin in the chamber 15.
  • the chamber 15 is supplied with glue through the glue line 13 and non-visible holes in the tube 10 which connect the glue line 13 to the chamber 15.
  • a seal 14 is inserted in the frontal bore 12, which comprises the tube 10.
  • the application head has a further glue connection 16.
