  • the invention relates to a machine for producing bag-like two-chamber packs from a flexible infusible material web, in particular tea bags, which are formed by folding and closed by clips, the material web being filled with divided portions of filling material and folded into a tube, running continuously and continuously Circulating means of transport controllable manufacturing units are arranged as workstations, each of which can be controlled from means installed outside the transport path and of which each unit folding elements for forming the bag bottom and the bag head, two arms for erecting the halves of the bag, in one of the arms a device for receiving the label as well as devices for separating the string of bags and the label thread provided with a label.
  • Such machines are known from DE-PS 21 2o 27o and DE-PS 24 o5 761 and have proven themselves extremely well in practice.
  • the construction effort for actuating the individual units of the workstations, which are arranged in a fixed manner in the embodiment according to DE-PS 21 20 27o, according to DE-PS 24 o5 761, on the other hand, on a means of transport that passes through the individual functional zones one after the other is extraordinary large.
  • the control elements are each arranged in the immediate vicinity of the workplace, so that the goods to be packaged inevitably fall on them. This often leads to malfunctions and operational interruptions, since the mostly small, integrated drive components are very sensitive to dust.
  • only the actuators of a work station can be controlled in this way.
  • control means and the transmission elements it should be possible to operate the units of several workstations arranged side by side at the same time without any significant additional construction work, so that several packaging units can be produced at the same time are kept to a considerable extent less than in the previously known comparable machines and there should be a high level of operational reliability.
  • this is achieved in that for the control of the moving parts of the individual units of a work station axially parallel, slidably and / or rotatably mounted shafts are provided as actuators, which are arranged directly or via intermediate elements by means of curved rulers arranged inside the transport means or laterally next to them or similar control means can be operated and which can be coupled to the moving parts of the unit.
  • shafts of the units of a work station prefferably and / or rotatably mounted together in one or more housings separate from the moving parts of the units.
  • the housings receiving the actuators can be arranged on one or both sides of the individual workstations, in the case of a plurality of workstations lying next to one another, preferably between them, so that the shafts are always properly supported.
  • two or more endless link chains guided over drivable sprockets can be provided in a simple manner, to which the housings receiving the actuators are fastened.
  • two angularly shaped envelopes should be provided, which are arranged separately from one another on displaceable shafts as actuators, whereby the envelopes can also be actuated individually by means of the curved rulers and the waves in such a way that first one of the tube parts of the material web leads past it is and that for making a fold of about 90 ° on the bag head when holding the bag immovably held and subsequently controllable for folding to each other are controllable.
  • a stop can be attached to one of the displaceable shafts, preferably to a shaft assigned to the envelopes, by means of which a cutting tool for cutting off the label thread can be actuated.
  • two concentric runners that can be pivoted towards one another can be provided for the installation of the two bag parts, which are attached to shafts that are rotatably mounted to one another in the housing as actuators — y for actuating the individual shafts, devices for converting a linear movement into a rotational movement are also appropriate , for example, gears or pulleys attached to these, which interact with toothed racks or traction elements, wedge gears or the like.
  • an angle lever which can be inserted into the area of the bag strand by means of a displaceable shaft as an actuating element and which is displaceably mounted on an axis and can be provided for pressing the bag strand by the angle lever can be provided for the bottom folding of the bag by the interaction of folding sheets and high beaters can be pivoted as an actuating means by means of a further shaft which can be rotated by means of a cam disk and a toothed rack and a toothed wheel.
  • the angle levers and / or axles and / or the components carrying them can be coupled to one another.
  • the machine designed according to the invention for the production of bag-like two-chamber packs is not only simpler in terms of construction and thus more economical than producing the known devices of this type, but also more versatile and extremely insensitive to interference. Above all, however, it is possible to double or multiply the packaging capacity of a machine with little additional effort. If the moving parts of the individual work stations are actuated by means of axially parallel, displaceable or rotatably mounted shafts, which abut one end against curved rulers or similar control means, it is thus possible to remove the control means from the work area and to arrange them at locations that are not the goods to be packaged are impaired. In this way, operational disruptions caused by dirt are reliably avoided.
  • the movable parts of a plurality of units arranged side by side can be actuated simultaneously by means of a shaft which can be designed in any length.
  • a shaft which can be designed in any length.
  • FIG. 1 with 1 machine for the production of bag-like two-chamber packs from a continuously fed material web 5, which is filled in a manner not shown with divided filler portions and folded into a tube, consists of an articulated chain 2, which in one Machine frame driven sprockets 3 and 4 is guided, and individual work stations A attached to the rotating link chain 2.
  • the individual work stations A each have the aggregates shown in FIGS. 3 to 7, by means of which the separation of the material web 5 into individual sections and of the label thread, the W-shaped folding of the bag 6 and the placement of the filled bag parts, the head folds 7, 7 'and the feeding of the label are to be carried out.
  • the movements of the adjustable parts of the units are controlled by means of curved rulers and are coordinated with one another and merge into one another in such a way that their interaction in the machine 1 automatically creates finished two-chamber bags 6 from the material web 5.
  • the curve rulers 33, 34, 53, 54, 72, 1 0 2 and 112 for controlling the Wellm31, 32 which are each mounted in a box-shaped housing 11, which is closed in a dustproof manner by covers 12 and 13.
  • 51, 52, 71, 1 0 1 and 111 are arranged laterally next to the transport chain 2 or between the sprockets 3 and 4, so that the shafts are partly subjected to an axial movement and partly to a rotary movement.
  • the shafts 31 and 32 are connected to envelopes 37 and 38 and receive their control movements by means of the fixed curve rulers 33 and 34, against which they rest by means of rollers 35 and 36, respectively.
  • springs 39 and 44 are provided for constant contact of the rollers 35 and 36, which are supported on the housing 11 and on disks 40 and 45 fastened to the shafts 31 and 32.
  • a stop 41 is also attached to the shaft 32, by means of which a knife 42 is actuated in order to separate the label thread 8 at the appropriate moment in cooperation with a stationary counter knife 43.
  • FIGS. 4 and 6 To make the W-shaped bottom fold of the bag 6 is used in FIGS. 4 and 6 shown angled hold-down 1 0 6, which by means of a shaft 1 0 1 in the Area of the material web 5 is insertable and can be pressed by means of a further shaft 111.
  • the floor is folded in cooperation with folding sheets 9 and the high beaters 61 and 62 for erecting the filled bag parts.
  • the shaft 101 abuts the cam disc lo2 over a pulley 103 and is by this counter to the force of a spring 1 0 4 extending to the housing 11, and a fixed to the shaft 1o1 disk 1 0 5 supported, axially displaceable.
  • the hold-down device 106 is firmly attached to a sleeve 107, which is slidably mounted on an axis 11o and is connected to the shaft 1o1 via a linkage 1o8, its axial movement is transmitted to the latter.
  • the axis 11o carrying it is pivoted by means of the rotatable shaft 111.
  • a curve ruler 112 is used for this purpose, on which a toothed rack 113, which is displaceably mounted in the housing 11, bears against a roller 114 and meshes with a toothed wheel 117 fastened to the shaft 111. If, for example, the rack 113 is moved upward, against the return spring 115 supported on it by a disk 116, the shaft 111 and the bracket 118, which is connected to it and rotated by 90 °, are pivoted through the axis 110 so that the hold-down device 106 comes to rest on the material web 5.
  • the individual movements are coordinated with one another in such a way that first the material web 5 can be introduced unhindered and only then can the bottom fold, the cutting and the turning up be carried out.
  • the scissor arms 74 and 75 shown in FIG. 7 are used to tear off the material web 5 into individual sections, which are connected to one another via a hinge pin 76 and which can be pivoted in the direction of the material web 5 by means of the axially displaceable shaft 71.
  • the scissor arms 74 and 75 are articulated via tabs 77 and 78 and bolts 79 and 80 to the shaft 71, which rests against the curve ruler 72 via a roller 73 and is displaceable against the force of a spring 82 supported by a disk 83.
  • a stop 81 is attached to the housing 11 carrying the shaft 71 at the level of the hinge pin 76.
  • This configuration makes it possible to transmit all the necessary control movements via the axially displaceable or rotatable shafts to the parts of the units to be moved in a work station and to arrange the control means outside the work area, so that, in particular, the return springs and the components required for deflection in the closed housing 11 are installed, soiling and the resulting malfunctions do not occur.
  • the overlapping individual control movements can easily be triggered and exactly adhered to by means of the curve linear.
