Definitions

  • the invention relates to a device for forming and dispensing packets from several flat individual products made of paper, cellulose wadding or the like, in which the individual products are fed to a stacking device lying at intervals between conveyor belts and the packets formed there are removed by a dispensing device connected downstream of the stacking device and be dissipated.
  • Such devices are generally known. They are used, for example, to combine products made from a paper web by cutting and folding, such as paper handkerchiefs, paper towels, etc., into packages consisting of counted individual pieces and, for example, to feed them to a packaging machine.
  • the devices can be preceded by a whole series of other machine groups, such as unwinding stations, printing machines, embossing calenders, folding devices and cross cutters.
  • a problem with such devices is that the speed at which the products can be fed to the device is limited by the fact that after each package is completed, a certain amount of time is required to feed the package from the stacker to the dispenser.
  • the uptake of the supplied individual products by the stacking device and the formation of a new packet can only be resumed when the previous packet has left the stacking device completely and the stacking device is returned to the initial state in which the formation of a new packet can be started .
  • the devices upstream of the device cannot either only run at a relatively slow speed or can only be operated intermittently, it is possible to connect several devices for the formation and delivery of parcels in parallel and to operate them in tandem, each of these devices using transport switches with which the machines supplying the products are connected.
  • Such systems are very expensive in terms of the necessary transport switches and the dispensing devices.
  • a device for packaging cross-folded carrier bags in outer bags is known (DE-A 23 60 628), in which there are two stacking devices arranged one behind the other as seen in the feed direction, which are alternately in operation and in which the products are fed to the second stacking device by the
  • the first stacking device takes place and each stacking device has a collecting cassette arranged below the conveyor belt system and an ejection device arranged above the conveyor belt system, which is provided with a vertically acting ejection plate, and the conveyor belt system consists at least in the area of the ejection device of parallel single belts which are arranged in such a way that the products are narrow Edge zones are detected and pressed through one of the ejection devices through the conveyor belt system into one of the collecting cassettes and in which the delivery device to the stacking devices continues is arranged that the parcels are discharged on the dispenser in a direction perpendicular to the feed direction.
  • This known device corresponds to the general concept of claim 1.
  • the ejection devices in the known device are driven by pneumatic piston-cylinder units. This has the disadvantage that the device is extremely limited in terms of the number of lifting and lowering movements of the ejection device per unit of time and high output rates cannot be achieved.
  • a device for conveying single sheets, in which there are two stacking devices arranged one behind the other, as seen in the feed direction, which are each operated alternately, the products being fed to the second stacking device by the first Stacking device is carried out.
  • the individual sheets are held by suction on conveyor belts arranged above them.
  • such a device is not useful for conveying and collecting folded products, since the suction effect only affects the top layer and the folded products would fall apart hanging on the conveyor belt. in the case of several products, only the top product would be recorded at all.
  • the object underlying the invention was to improve a device with the features from the preamble of claim 1 so that it is possible with relatively little design effort, individual products, in particular folded individual products and several individual products combined in small packages, at high speed continuously feed the device, selectively convey it to the first or second high-speed stacking device and continuously discharge the packets formed there without the feed process having to be interrupted.
  • the invention is based on the knowledge that it is not possible to drive the ejection devices pneumatically, hydraulically or electrically at the required high production speeds, because with these drives the pushing of the Individual products are not possible with the required accuracy due to the conveyor belt system in the collection cassettes.
  • the basic idea of the solution is to provide a purely mechanical drive that works with the required accuracy and speed, with a particular problem to be solved was also to control the alternating work of the two stacking devices with the required accuracy.
  • the device according to the invention can be produced in a structurally simple manner, in particular in the embodiments described in the subclaims.
  • the stacking devices are preceded by a collecting device.
  • Claims 11 and 12 indicate simple mechanical constructions that work with one or two cams. However, it is also possible in principle to design the control entirely as a pneumatic sequence control.
  • the features of claim 14 are realized, with which a particularly gentle and clean stacking of the individual products in the collecting cassettes is achieved.
  • the device shown in FIGS. 1 to 6 for the formation and delivery of packets from individual products, for example paper towels, has two stacking devices, of which a first is generally designated BC and a second is generally designated DE.
  • the two stacking devices BC and DE are arranged one behind the other, and a conveyor belt consisting of several individual belts 1, 2 and 3, which will be explained in more detail below, is guided such that it first passes through the stacking device BC and then through the stacking device DE.
  • the device is preceded by a cross cutter 26, which is only indicated, and which may also be preceded by further machines which are not specifically shown.
  • the individual products separated from the cross cutter 26 are fed to the first stacking device B-C in the direction Z after passing through a collecting device explained in more detail below.
  • the principle of the device and the flow of the products can best be read from FIG. 2.
  • a first packet P is formed from the supplied individual products A.
  • this package is fed onto one of two transport chains 17 of a delivery device and at the same time the stacking device BC is blocked in order to be made continuous for the following individual products A, which are also supplied to the second stacking device DE, in which the next packet P is already formed while the first packet is being fed to the delivery device.
  • FIGS. 1 and 2 The details of the overall structure of the device can be seen in FIGS. 1 and 2.
  • Each of the two stacking devices BC and DE has an ejection device B and D arranged above the conveyor belt 1-2-3.
  • Each of the ejection devices has a lifting frame 4, which is guided in rod guides 5 so as to be vertically movable, and an ejection plate 25 on its underside is arranged.
  • An eccentric disc 6 (see also FIG. 4) is arranged inside the lifting frame 4 and is connected to a drive shaft 10, which leads to a drive 12.
  • the lifting frame 4 is supported by a support roller 7 on the eccentric 6. From the drive 12, the lifting frame 4 is raised by the eccentric disc 6 against the force of pressure springs 8 and in this way is caused to make continuous lifting and lowering movements.
  • each stacking device has a collecting cassette, which is denoted overall by C or E.
  • Each of the collecting cassettes C and E has a controlled lowerable floor 15 on which a storage plate 16 is supported by springs 38.
  • a control device shown in FIG. 3 can be used to control the lowering of the base, in FIG. 3 the two cassette bases are designated 15a and 15b.
  • Each cassette base 15a, 15b is connected to a control shaft 32a, 32b via a pivot lever 33a, 33b.
  • Control levers 34a, 34b are arranged on the control shafts 32a and 32b and are guided on cam disks 31a, 31b.
  • the two cams 31a and 31b are designed such that, via the mechanism shown in FIG. 3, the two cassette bottoms 15a and 15b execute a movement which is phase-shifted by approximately 180 ° with respect to one another, in which they are first slowly lowered, then lowered more quickly to an end position and finally be raised again after a standstill.
  • the collecting cassettes C and E are designed as collecting shafts, which are delimited at their four corners by perpendicular angle profiles for centering the packets P.
  • the rear angle profiles 20 are arranged in a fixed manner, while the front angle profiles 21 a and 21 b are arranged so as to be rotatable about an axis perpendicular to the bottom of the cassette in order to clear the passage path for the parcels P from the collecting cassette onto the transport chain 17.
  • the conveyor belt is constructed in a manner known per se from a plurality of groups of belts running in parallel, which are guided in the region of the two ejection devices B, D in the manner shown in FIG. 5.
  • the conveyor belt consists of three belt groups, namely two lower edge zone belts 1, which are designed as flat belts, two upper edge zone belts 2, which are designed as round belts, and a central belt 3, which is designed as a flat belt.
  • the edge zone belts 1 and 2 are guided so that that each individual product A is covered by them in narrow marginal zones. In order to avoid a large return path for the two lower marginal zone bands, these are guided in the manner shown in FIGS. 1 and 5.
  • the lower edge zone bands 1 are returned after the band has been folded into a position in which the band plane is rotated by 90 °, past the collecting cassettes C and E.
  • a center belt 3 is also provided in the area of the ejection devices B and D.
  • the ejection plate 25 arranged on the lifting frame 4 is therefore designed as a double plate which is fastened to the lifting frame 4 via a U-shaped holder 37.
  • the double plate 25 dips into the area between the upper candle zone belts 2 and the central belt 3 and presses the individual product A down into one of the collecting cassettes C or E.
  • the conveyor belt can be included both on the top and on the bottom of the individual products A. or several center bands to provide a more stable section guide.

  • This stop 14 is arranged and the two radii of the control disk 11 are dimensioned such that when the lifting frame 4 is raised, the peripheral region of the control disk 11 with a larger radius can slide straight under the stop 14, but the lifting frame 4, as long as the peripheral section with a larger radius is located under the stop 14, with a corresponding position of the eccentric disc 6, despite the action of the compression springs 8, cannot perform a lowering movement.
  • the peripheral area with a smaller radius is below the stop 14, the lifting frame 4 can carry out its lifting and lowering movements unhindered. The lowering movements of the lifting frame 4 are thus blocked in a certain position of the control disk 11. The eccentric disc 6 then continues to run without affecting the lifting frame 4.
  • the number of strokes or the blocking time can be predetermined as desired, the same number of revolutions of the eccentric disk 6 taking place during a blocking time as in the operating time.
