    Title: Machine for the production of rolled wafer packets
    The invention relates to a machine for producing rolled wafer packets. The rolled wafer packets are made in the horizontally oriented bag rolling devices of the machine. The machine has an elongated machine frame in which the bag rolling devices are arranged one behind the other along an orbit extending in the longitudinal direction of the machine frame. The machine has an endless conveyor disposed along the orbit, carrying the bag rolling devices, which conveys the bag rolling devices along the orbit from the machine-top input station to the discharge station located at the machine bottom. The endless conveyor has arranged at the side edges of the orbit transport chains to which the support frame of the bag rolling devices are attached.
    Such machines are z. B. from AT 410 309 B and US 6,227,103 B1 known.
    Rolled wafer bags are made from flat wafer patties. The baked wafer patties are plastically deformable in the baked, hot state. When cooled to room temperature, the wafer patties solidify into dimensionally stable, crispy-brittle structures. The wafer patties are introduced in the hot, plastically deformable state in the bag rolling devices and rolled up into bags in the bag rolling devices. The finished, hot and still plastically deformable bags are issued from the bag rolling devices. When cooled to room temperature, the bags solidify into dimensionally stable, crispy-brittle structures.
    The invention proposes a new machine of the type mentioned above. The new machine according to the invention is characterized in that each bag rolling device rigidly connected to its support frame roll form, a slidable along its support frame Tütenabstreifer and along its supporting frame rolling mandrel, wherein the roll form is arranged on a lateral end portion of the support frame, the Tütenabstreifer on a slidable along the support frame, the first carriage is arranged and the rolling mandrel is arranged on a longitudinally displaceable along the support frame, second carriage.
    The machine according to the invention provides horizontally oriented bag rolling devices. These have horizontally oriented support frame with which the horizontally oriented roll shapes are rigidly connected. The support frames extend in the transverse direction of the machine frame and are attached to the side edges of the orbit on the transport chains of the endless conveyor. In each bag rolling device, the roll form rigidly connected to the support frame is horizontally oriented and arranged transversely to the circulation direction of the bag rolling devices. As a result, the roll forms which are immovably arranged in the bag rolling devices are always in the same pickup position for the wafer patties when they pass through the input station. Due to the roll molds, which are immovably arranged in the bag rolling devices, alignment errors of the wafer patties relative to the roll molds are avoided when the wafer patties are introduced into the roll molds.
    Each bag rolling device comprises a roller unit arranged in the support frame, which can be pulled apart in the longitudinal direction of the support frame and can be pushed together in the longitudinal direction of the support frame. The rolling unit consists of the horizontally oriented roll form, which is rigidly connected to the support frame, from the slidable in the support frame Tütenabstreifer, which is arranged on a displaceable in the longitudinal direction of the support frame, first carriage, and from the slidable in the support frame, horizontally oriented rolling mandrel, the is arranged on a displaceable in the longitudinal direction of the support frame, the second carriage. The roller unit is pushed or pulled apart by moving the two slides in the longitudinal direction of the support frame.
    The endless conveyor conveys the bag rolling devices along the orbit from the input station to the output station and back to the input station. On the way from the output station to the input station, the roll units are pushed together or closed in the longitudinal direction in the bag rolling devices. In the input station, a hot waffle flat is introduced into the closed roll unit for each bag rolling device and rolled into a bag between the roll form and the roll dome. During the transport of the bag rolling devices from the input station to the output station, the roller units remain closed. In the dispensing station, with each bag rolling device, the roller unit is pulled apart in the longitudinal direction with the aid of the two carriages and the bag is dispensed from the roller unit. Here, the rolling mandrel is first pulled out with the bag arranged on it from the roll form and the Tütenabstreifer is pushed together with the rolling mandrel to the rear. Then the bag is stripped off the rolling mandrel by the bag scraper. To strip the bag, the first carriage is pushed forward relative to the second carriage or the second carriage is pushed backwards relative to the first carriage.
    According to a further feature of the invention can be provided that on a second carriage in a bearing block rotatably mounted Rolldornwelle is provided which carries the rolling mandrel at the front end and at the rear end a rolling mandrel drive wheel.
    In this embodiment, the rolling mandrel is set on the rolling mandrel drive wheel in rotation. The rolling mandrel drive wheel is driven by a drive means disposed at the orbit of the bag rolling devices with which the rolling mandrel driving wheels of the bag rolling devices engage when the bag rolling devices are conveyed in the longitudinal direction of the machine to the input station and through the input station.

When rolling in the waffle pile, the roll form results in an increase in the wall thickness of the resulting bag. By this increase in wall thickness of the rolling mandrel is pushed back axially. As a result, the rolling mandrel shaft is pushed together axially and in the polygonal coupling, the two coupling sections are axially displaced from each other. The introduced from the rolling mandrel drive wheel in the rolling mandrel shaft torque is transmitted during the axial displacement of the two coupling portions of the polygon clutch unchanged via the polygon coupling on the rolling mandrel bearing, inner shaft of the rolling mandrel shaft.
    According to a further feature of the invention, it may be provided that the polygon coupling is arranged in the rear part of the rolling mandrel shaft, wherein an inner coupling section formed by the inner shaft and formed on the outside as a polygonal shaft is formed in one of the outer sleeve , outer coupling portion which is formed on the inside as a polygonal sleeve, is positively received.
    In this embodiment, the rolling mandrel drive wheel arranged at the rear end of the rolling mandrel shaft can be arranged directly above the polygon coupling. The rolling mandrel drive wheel then sits on the outer coupling portion of the polygon coupling. The introduced from the rolling mandrel drive wheel in the rolling mandrel shaft torque is transmitted in the polygonal coupling from the outer coupling portion on the positively received in this, inner coupling portion which is arranged at the rear end of the rolling mandrel bearing, inner shaft.

    The machine 1 has an input station 3 arranged at the top, in which the waffles 4 to be rolled are introduced into the bag rolling devices 5 circulating in the machine 1. The bag rolling devices 5 are arranged one behind the other along an orbit extending in the longitudinal direction of the machine 1 and are moved by the endless conveyor 6 of the machine 1 along this orbit through the machine 1. The wafer flat 4 are rolled into bags in the bag rolling devices 5. The rolled-up wafer packets produced in the bag rolling devices 5 are dispensed at the dispensing station 7 of the machine 1. The output station 7 is arranged on the underside of the machine 1. The wafer bags fall down from the machine 1 and arranged on the base 2 conveyor.
    Machine 1 has an elongated machine frame 8 having a front side wall 8a, a rear side wall 8b, a left end wall 8c, and a right end wall 8d (Figure 2). The machine frame 8 is seated on the underframe 2.
    In the machine frame 8, the orbit of the bag rolling devices 5 is arranged. The orbit comprises two, in the longitudinal direction of the machine 1 extending, stacked, horizontal track sections, which are interconnected by two semicircular track sections.
    The bag rolling devices 5 are conveyed by the endless conveyor 6 in the longitudinal direction of the machine frame 8 through the orbit. The elongated Tütenrollvorrichtungen 5 are aligned horizontally and arranged transversely to the direction of rotation.
    The endless conveyor 6 has two endless transport chains 6a, 6b which extend along the orbit and are arranged on the two side edges of the orbit. The bag rolling devices 5 are arranged between the two transport chains 6a, 6b. The front ends of the bag rolling devices 5 are fixed to the front transport chain 6a, which is disposed adjacent to the front side wall 8a of the machine frame 8. The rear ends of the bag rolling devices 5 are fixed to the rear transport chain 6b, which is disposed adjacent to the rear side wall 8b of the machine frame 8.
    The two transport chains 6a, 6b run at the ends of the endless conveyor 6 via deflection wheels 6c and 6d. The semicircular path portions of the orbit are arranged along these guide wheels 6c and 6d. The endless conveyor 6 is driven via the two arranged at its front end Kettenumlenkräder 6c. The Kettenumlenkräder 6c are connected via a horizontal drive shaft 6e with the (not shown) drive motor of the endless conveyor 6.
    Each bag rolling device 5 has an elongated support frame 9 extending in the transverse direction of the machine frame 8. The roll form 10 of the bag rolling device 5 is arranged adjacent to the front end of the support frame 9 and rigidly connected to the support frame 9. The roll form 10 has a lateral insertion slot for the wafer flat. On the outside of the roll form 10, a slanted plate 10a is mounted, on which the wafer patties slide into the insertion slot.

    The rolling mandrel shaft 67 is formed as an axially collapsible rolling mandrel shaft.
    The rolling mandrel shaft 67 provides an outer sleeve 69, which carries the rolling mandrel drive wheel 68 and is rotatably mounted in the bearing block 66, but axially non-displaceable. The roll mandrel shaft 67 provides an inner shaft 70 which carries the rolling mandrel 63, which is arranged in the interior of the outer sleeve 69 and axially displaceable relative to the outer sleeve 69. The rolling mandrel shaft 67 includes a polygon coupling 71 mechanically connecting the outer sleeve 69 to the inner shaft 70 and disposed at the rear of the rolling mandrel shaft 67.
    The polygon coupling 71 provides an outer coupling portion 72 formed by the rear end portion of the outer sleeve 69, which is formed on the inside as a polygonal sleeve. The polygon coupling 71 provides an inner coupling portion 73 formed by the rear end portion of the inner shaft 70, which is formed on the outside as a polygonal shaft. The inner coupling portion 73 is positively received in the outer coupling portion 72 and slidable in the longitudinal direction. The two coupling sections 72, 73 of the polygonal coupling 71 can be moved during the torque transmission, i. H. under load, be shifted against each other.
    In the second carriage 65, the torque introduced by the rolling mandrel drive wheel 68 on the outer sleeve 69 into the rolling mandrel shaft 67 is transmitted via the polygon coupling 71 to the inner shaft 70 which is axially displaceable in the outer sleeve 69 and the rolling mandrel 63 at the front end wearing. The rolling mandrel 63 can be reciprocated horizontally in the second carriage 65 during the torque transmission without moving the second carriage 65 itself. When horizontal displacement of the rolling mandrel 63 only the rolling mandrel shaft is pushed together or pulled apart.
    The second carriage 65 may remain when rolling a Waffelfladens in the front end position, even if there is an increase in the wall thickness of the resulting bag when rolling the waffle and the rolling mandrel 63 is to retreat slightly so as not to flatten the wafer flat. This rearward movement of the rolling mandrel 63 is absorbed by the axially compressible rolling mandrel shaft 67. The inner shaft 70 carrying the rolling mandrel 63 is pushed back axially in the outer sleeve 69 carrying the rolling mandrel drive wheel 68. The torque transfer from the outer sleeve 69 to the inner shaft 70 is maintained unchanged by the polygon coupling 71.
    The rolling mandrel 63 is resiliently supported on the outer sleeve 69 of the rolling mandrel shaft 67 by a coil spring 74. The coil spring 74 is disposed on the inner shaft 70 between the front end portion of the inner shaft 70 supporting the rolling mandrel 63 and the front end of the outer sleeve 69.
    The coil spring 74 determines the contact pressure with which the rolling mandrel 63 is pressed against the retracted into the roll mold 60 wafer flat when rolling to a bag. When pulling out the rolling mandrel 63 from the roll form 60, the coil spring 74 pushes the rolling mandrel 63 back to its starting position.
