Definitions

  • the invention relates to a method and an apparatus for stacking, i.e. for forming, holding, separating and transporting stacks, in particular stacks consisting of envelopes or the like. Behind a depositing device which places individually arriving envelopes with one of their edges on a stacking surface.
  • a method and an apparatus of the type mentioned are known from CH-A-607 979. Thereafter, two stack supports are provided, namely a leading stack support which engages the front end of the stack in the transport direction and thereby holds the stacked parts secured in their vertical position against falling over, and a further stack support which corresponds to a length of a finished stack measured in the transport direction Distance behind the leading stack support is inserted from below into the stack being formed.
  • This further stack support is divided into a lower trailing support section and an upper leading support section.
  • the trailing lower support section forms, together with the leading stack support, a transport unit that moves the finished stack in the transport direction at a higher speed than the stacking speed, while the leading support section only moves forward at the speed corresponding to the stacking process and thereby supports the newly formed subsequent stack.
  • the trailing support section is moved downwards and in the direction of the depositing device, while the advancing deposit support is moved back to the support position for the subsequent stack which is formed, whereupon the leading support section is also extended downward and in the direction of the depositing device is reset, in order to then be retracted together with the trailing lower support section at the appropriate point in the stack formed between two stack parts.
  • the known device works in principle satisfactorily, but can still be improved and made more efficient.
  • the object of the invention is to improve the aforementioned method and the corresponding device and to make it even more efficient.
  • the invention provides that during the removal of one stack and the simultaneous formation of the next stack, several stack supports are simultaneously active and are moved into the path of movement of the stack and out of its path of movement and along the path of movement.
  • stack supports serving as a transport unit
  • further stack supports are, like the stack supports serving as a transport unit, movable stack supports into and out of the movement path of the stack and along the movement path of the stack, although the movement along the movement path is limited only to the area of stack formation.
  • the stack supports, which can only be moved in the area of the stack formation, are also effective until their function is taken over by the other two stack supports, which also serve as a transport unit.
  • three stack supports are moved from one side transversely to the movement path and along the movement path of the stack and from a second side
  • a fourth stack support is moved into and out of the movement path, and at times during the formation of the stack along the movement path.
  • the movement of the three stack supports preferably takes place from bottom to top and back and in the longitudinal direction of the movement path, while the movement of the individual stack supports takes place from top to bottom and back and in the direction of the movement path of the stack.
  • the stack supports act partly simultaneously and partly alternately and complement one another, a continuous movement sequence is possible without interruption while the stacks are also continuously formed and the overall speed of the individual parts is low overall. This is associated with a high degree of operational safety and thus a low susceptibility to failure.
  • a device 1 for stacking, for example, envelopes 3 coming from a feed station 2 comprises, according to FIG. 5, a depositing device 4 with serrated lock washers 5.
  • Feeding stations 2 and depositing devices 4 of the type of interest here are known in principle and are not the subject of the invention.
  • FIG. 5 also shows, the continuously and individually arriving envelopes 3 are placed with one of their edges 6 by the depositing device 4 on a stacking surface 7 of the device 1 and are initially held there by a first leading stack support 8.
  • leading stack support means that this stack support is located in the front in the direction of stack formation - ie in the direction of arrow a in FIG. 5 - and a stack 10 or finished stack 11 is formed at its front end pointing in the direction ⁇ supports.
  • a second leading stack support 9 takes the place of the first leading stack support 8 and holds the forming stack 10, thereby the first leading stack support 8 out of the path of movement of the stack being formed 10 can be moved out. This is also shown in Fig. 6.
  • a third leading stack support 12 and a stack support 13 trailing in the transport direction take over the stack 11, the trailing stack support 13 engaging at the rear end of the stack.
  • the two stack supports 12 and 13 together form a transport unit and transport the finished stack 11 out of the area of the stack formation point, for example to a turning and nesting station 14, as shown in FIGS. 2 to 5 and 6, respectively.
  • the first leading stacking support 8 When the two stacking supports 12 and 13 serving as the transport unit take over the stack 11, the first leading stacking support 8 is simultaneously moved in front of the next part to be stacked.
  • the first leading stack support 8 therefore also serves as a separating element between a completed, complete stack 11 and the next stack 10 that is being formed (FIGS. 2 and 3).
  • stack supports 8, 9 and 12, 13 are thus active and move both in the movement path of the stacks 10, 11 and out of their movement path and they move also along the movement path of the stacks 10, 11.
  • Three stack supports 8, 12 and 13 move from one side transversely to the movement path of the stacks 10, 11 and along the movement path, while the fourth stack support 9 moves from a second side into the Movement path in and out of this and temporarily moved along the movement path during the stack formation.
  • the second leading stack support 9 is pivoted from above in front of the stack 10 being formed and moves during the stack formation along the path of movement of the stack 10 until it finally swings up again and then in the direction Storage device 4 moved back.
  • the second leading stack support 9 holds the stack 10 being formed, while the stack supports 12 and 13 serving as a transport unit, like the first leading stack support 8, are in a standby position. In this standby position, the stack supports 8 and 13 are located at a short distance in front of the stack 10 on its side facing the depositing device 4 and project with their free ends 16 somewhat over the stacking surface 7.
  • Fig. 2 the stack 11 has reached its full size.
  • the second leading stack support 9 and the third leading stack support 12 belonging to the transport unit are located in one plane.
  • the trailing stack support 13 and the first leading stack support 8 located directly next to it have moved from the ready position according to FIG. 1 to the last part 15 of the complete stack 11. This takes place at a relatively low level, so that initially both the leading stack support 12 and the trailing stack support 13 abut the stack 11 only with their upper ends 16.
  • the two stack supports 12 and 13 according to FIG. 3 then move upwards on the stack and at the same time somewhat in the direction of movement of the stack 11 to be transported away.
  • the stack 10 or 11 expediently rests in the stack formation area on the upper run of a conveyor belt 17 which is guided around deflecting rollers 18 to 23 and around a driving deflecting roller 24.
  • the transport speed of the two stack supports 12 and 13 forming the transport unit is greater than that of the conveyor belt 17, so that a gap 25 quickly arises to the next stack 10 which is being formed (FIG. 4).
  • This next stack 10 which is being formed is held by the first leading stack support 8 which, together with the trailing stack support 13, has been moved from the ready position according to FIG. 1 to the last part 15 after completion of the stack 10 according to FIG. 2, this too was first carried out at a low level, whereupon the first leading stack support 8 is moved transversely to the stacking direction from the position according to FIG.
  • the second leading stack support 9 moves out of the movement path of the stack 11 when the third leading stack support 12 has reached its upper position according to FIG. 3.
  • the stack support 9 pivots out of the path of movement of the stack 11 (FIG. 4).
  • FIG. 6 shows the situation in which the turning and nesting station 14 has taken over the stack 11 with its turning fork 26. Furthermore, a folding box 27 has already been pushed over the stack 11.
  • the stack supports 12 and 13 serving as a transport unit can therefore be detached from the stack 11, for which purpose they are removed from the stack. According to the exemplary embodiment, this is done by lowering the two stack supports 12 and 13.
  • the second leading stack support 9 which can be swiveled in from above, has taken over the securing of the stack 10 being formed, as a comparison of FIGS. 5 and 6 shows.
  • the first leading stack support 8 was also lowered in accordance with the exemplary embodiment and is therefore no longer able to hold the stack 10 that is being formed (FIG. 6).
  • the three stack supports 8, 12 and 13 which can be moved from a common side transversely to the path of movement of the stacks 10, 11 then move into a waiting position on the right in FIG. 7.
