Definitions

  • the invention relates to a device for separating products to be cut from a web of material, e.g. of filter inserts for the preparation of brewing drinks, which has a continuously rotating belt drive with an upper belt and a lower belt, between which the material web residues can be gripped and then removed from their original transport direction.
  • a device for separating products to be cut from a web of material e.g. of filter inserts for the preparation of brewing drinks
  • a continuously rotating belt drive with an upper belt and a lower belt, between which the material web residues can be gripped and then removed from their original transport direction.
  • a device of this type which has become known through prior public use, has an upper belt located above the material web and equipped with two round cord belts with two deflection rollers, which are arranged perpendicular to one another and to the material web, whereas the lower belt two in the transport direction of the material web one behind the other and a third arranged vertically above it Has deflection roller that drive a round cord belt.
  • the round cord belt of the lower belt and the two round belt belts of the upper belt touch each other at at least two contact lines.
  • the axes of rotation of the deflection rollers of the upper belt and the lower belt are aligned perpendicular to the direction of transport of the material web.
  • a known device of this type is used for separating filter inserts to be removed from a material web in the contour cut, the latter terminating with one side edge of the material web, but ending with its other side edges, leaving a continuous edge of the material web in front of its second side edge.
  • the resulting material web strip between the second side edge of the filter inserts and the second side edge of the material web runs into a receiving slot between an assigned pair of deflection rollers of the upper and lower belts and is then pulled upwards perpendicular to the direction of transport and separated from the filter inserts already cut in the contour cut.
  • the filter inserts Before the separation process, the filter inserts have already been sucked in by a vacuum belt which, on the one hand, is intended to prevent the filter inserts from being carried along and, on the other hand, is to ensure their further transport to a stacking and packaging device.
  • contour cuts are cut using the so-called squeeze cut method (mass roller squeezes against a smooth counter-pressure cylinder), with the cutting tools becoming dull as soon as they are first used. Since the service life of these cutting tools is relatively long until they become unusable, it is more and more common that there is an ever increasing bond between material web residues and the product to be detached therefrom over a relatively long operating time.
  • squeeze cut method mass roller squeezes against a smooth counter-pressure cylinder
  • the invention has for its object to provide a device of the type mentioned, which ensures a safe separation of product and material web remainder with purely mechanical, non-positive and / or positive-locking means and at the same time a full utilization of the material web width and length for the product to be cut from it.
  • the device is provided with a second belt drive with a second upper and lower belt, which are arranged above and below the material web, and in that at least one belt of the first and second belt drives on its contact surface with the other belt Raised zones are provided, between which at the moment of separation of the product and material web residue from the second belt drive only the cut product and from the first belt drive only the material web residue is held clampable.
  • the belts of these belt drives can consist both of entrophy-elastic material, such as rubber or rubber, and can also be produced as chain drives from metallic elements.
  • Both the upper and the lower belt of the first and second belt drives can be provided with mutually corresponding, raised zones, which in turn advantageously have congruent configurations.
  • both the clamping of the product to be removed from the material web and that of the remainder of the material web can be controlled with millimeter precision and thus also in time in the transport direction of the material web without the individual products still having to be spaced apart in the transport direction.
  • a continuous strip of material web on one side edge as in the previously known device described in the prior art is also no longer necessary.
  • the first belt drive is arranged at a horizontal angle of attack ⁇ in the top view of the transport plane to the second belt drive. Due to the angle of attack ⁇ of this first belt drive, for example, at the same circumferential speeds of the two belt drives, the material web residue gripped by the first belt drive is nevertheless removed in relation to the transport movement of the cut product in delayed form. since the speed components are different in relation to the direction of transport.
  • the first belt drive is also inclined by a vertical angle of attack ⁇ relative to the second belt drive.
  • the angle of attack ⁇ and / or the angle of attack ⁇ are dimensioned depending on the shape and size of the contour cut and the remaining material web residue such that the leading product is clamped by the raised zones of the second belt drive at the same moment as the lagging material web rest by the raised zones of the first belt drive is detected.
  • angles of attack ⁇ , ⁇ can be individually adapted to the respective requirements, these requirements being understood to mean both the tear properties of the material web and the clinging together of product and material web residues due to a cutting tool becoming blunt.
  • the horizontal and vertical angle of attack ⁇ , ⁇ of the first belt drive can be adjusted by means of a lockable swivel device, e.g. a ball-and-socket joint, changeable, on which the first belt drive is arranged.
  • a lockable swivel device e.g. a ball-and-socket joint, changeable, on which the first belt drive is arranged.
  • the adjustment and locking of the swivel device can also be carried out by an actuator.
  • a first belt drive is arranged on both sides of the second belt drive at the most favorable angle of attack ⁇ , ⁇ .
  • the first two belt drives can each be inclined to the same side of the transport plane of the material web at angle ⁇ but also to different sides. The choice of these two alternative arrangements depends primarily on the shape of the contour cut and the material web remnants and on the most favorable direction of tearing of the material used in relation to the transport direction.
  • the raised zones each consist of contiguous, flat levels, called useful areas for short.
  • the useful areas are advantageous, Particularly in the case of small contour areas of the products and / or the material web remnants, the latter are largely or partially geometrically similar. With this design, the products and also the material web remnants are grasped in a large area and thus undesirable material tensions, which can possibly also lead to undesirable tears, are avoided.
  • the raised zones in the case of large contour areas of the product and / or the material web catch from several knobs, tooth-like elevations or the like, the imaginary, outer connecting line of which is geometrically similar in whole or in part to the shape of these contour areas.
  • This type of design of the tapes has the advantage, in particular when they are perforated, that the knobs, teeth or the like can be detachably and thus displaceably and thus variably attached to the respective tape and also adjust the contour of the respective product and / or material web stop or to be able to adjust.
  • the remnant of the meterial baby is grasped by the first belt drive with a protrusion projecting beyond a side edge, and this side edge at the outlet of the first belt drive is a third, known per se, the Belt drive which detects protrusion is assigned, the upper band of which two and the lower band of which have a round cord belt which touch each other at at least two contact lines.
  • This arrangement allows the material web residues captured by the first belt drive to be transported away on a space curve, since the third belt drive consisting of circular pulleys enables a spatial transport curve.
  • a funnel of a suction device known per se can also be arranged at the outlet of the first belt drive, which suction device sucks off the material web residues thrown into the funnel by the first belt drive for reprocessing into a collecting container.
  • a folded material web 1 is embossed on an angular line forming the later bottom edge 2 and a side edge 3 of a filter insert 4, whereby the material web sides lying one on top of the other are connected on this line 2, 3. Then the material web 1 runs between a knife roller 5 and a smooth impression cylinder 6, a cut being made along the line 7, 8 and 9.
  • the configuration of the essentially trapazoedalen filter insert 4 cut thereby essentially consists of the straight bottom edge 7, an embossed side edge 8 and a folded side edge 10, and the opening edge 9 with the ear-shaped opening aid 9 '. Between two adjacent filter inserts 4 there is a material web residue 11 which has to be removed after the cutting process.
  • this material web residue 11 consists of a continuous edge 101 made of a larger trapezoidal section 102 and a small, trapezoidal section 103 near the folded side edge 10.
  • the device which has become known through prior public use, according to the preamble of the current claim 1 consisted of an upper belt 13 arranged above the material web 1 and equipped with two round cord belts 12 with two deflection rollers 14, 15, which are attached perpendicularly to one another and to the material web 1, whereas the lower belt 16 has two deflecting rollers 18, 19 arranged one behind the other in the transport direction of arrow 17 and a third deflecting roller 20 arranged vertically above it, which only drive a round cord belt 21.
  • the axes of rotation 24 to 28 of the deflection rollers 14, 15, 18, 19, 20 of the upper belt 13 and the lower belt 16 are aligned perpendicular to the transport direction 17 of the material web 1.
  • the filter inserts 4 are sucked in by a vacuum belt 104 before the separation process between them and the material web residue 11, which on the one hand prevents the filter inserts 4 from being carried away and on the other hand ensures their further transport to a stacking and packaging device, not shown.
  • the material web edge strip 101 runs into the slot 29 between the deflection rollers 15 and 18, is clamped in there between the round cord belts 12, 21 and is fed in the direction of the arrows 30 to a suction device 31 indicated by dash-dotted lines.
  • the disadvantage is this device that it always requires a continuous edge strip 101 of the material web 1 to separate the material web remainder 11, which must not be included in the contour cut 7, 8, 9 of the filter inserts 4.
  • the subject invention is strength in a first alternative, shown in Figs. 1 and 2 and in an alternative zwniten in F. 3 shown.
  • the same parts are provided with the same reference numbers. 4 and 5, the first belt drive 13, 16 was replaced by a first belt drive 32 and then vacuum belt 104 by a second belt drive 33 .
  • the first belt drive 33 consists of an upper belt 34 and a lower belt 35, the second belt drive 33 likewise having an upper belt 35 and a lower belt 37.
  • the two lower belts 35, 37 are each arranged below and the two upper belts 34, 36 above the material web 1.
  • there is only one band at a time namely always the upper band 34, 36 provided with raised zones 38, 39.
  • These raised zones 38 of the first belt drive 32 and the raised zones 39 of the second belt riser 33 are identified in FIG. 2 with cross hatching.
  • the upper belt 34 and the lower belt 35 of the first belt drive 32 are driven by two approximately congruently superimposed pairs of rollers 40, 41, like the upper belt 36 by the deflecting rollers 42, 43 and the lower belt 37 by the deflecting rollers 44, 45 is driven.
  • the first belt drive 32 is offset from the second belt drive 33 by the horizontal setting angle ⁇ and, according to FIG. 1, is inclined by the vertical setting angle ⁇ .
  • the horizontal angle of attack ⁇ and / or the vertical angle of attack ⁇ are, depending on the shape and size of the contour cut according to lines 7, 8, 9 and the remaining material bahar 11, dimensioned such that the leading product, here a filter insert 4, of the raised Zones 39 of the second belt drive 33 are clamped at the same instant as the trailing material web residue 11 is gripped by the raised zones 33 of the first belt drive 32.
  • the material web residue 11 gripped by the first belt drive 32 is removed in a delayed manner with respect to the transport movement of the cut product 4, since the speed components relate to the transport direction are different.
  • the new device 32, 33 no longer requires a continuous strip of material web 101 (see FIG. 5), as a result of which production is reduced by approximately 10% compared to the prior art.
  • the deflection roller 40 of the first belt drive 32 can be followed, for example, by the dash-dotted suction funnel 31 through which the material web residues 11 thrown out are sucked in and a collecting container (not shown) can be forwarded.
  • the material web residue 11 is divided into a larger material web residue 11 'and a smaller material web residue gusset 11 ", which are connected to one another by a narrow web 11'".
  • a low-waste production of the filter inserts 4 is still possible in the sense of the task in that their contour cut takes place so closely that the connecting web 13 '''is reduced to zero.
  • the two separate material web residues 11 ′ and 11 ′′ then arise, which must be led out separately from the transport direction 17. This is carried out in a further development of the invention 3.
  • a first belt drive 32 is arranged, one of which leads the waste residue 11 ′ and the other the waste residue 11 ′′ out of the transport direction 17 of the filter inserts 4.
  • the raised zone 38 'for the material web rest 11 is triangular and geometrically similar to the material web rest 11". This is always advantageous if the material web residues, here 11 ′′, are relatively small in area. With larger contours, for example in the case of material web residue 11 ', the raised zone 38 of the first belt drive 32 corresponds only to a partial area of the material web residue 11'. However, it is also possible to produce the raised zones 38 in the case of large contour areas of the product 4 and / or the material web residues 11 'from a plurality of knobs, the imaginary outer connecting line of which is wholly or partly geometrically similar to the shape of this contour area 11'.
