Definitions

  • the invention relates to a process for the production of defined stacks of folded or unfolded sheets or sheet-shaped objects, in which the individually fed sheets are placed standing on a horizontal base and the separation into individual stacks is carried out by a separating support which can be moved parallel to the base at the rate of stacking.
  • a method for producing defined stacks of this type is described in DE 27 32 837 C2.
  • the sheets are separated into individual stacks by a plurality of separating supports attached to a circumferential chain belt.
  • the separation supports are moved into the stacking level in the area of the deflection of the chain belt.
  • the subsequent separation support located immediately behind the deflection point of the chain belt is briefly accelerated by means of a preloaded piston-spring unit until it rests against the back of the stack formed and thereby forms the rear parting plane.
  • a disadvantage of this known method is that the separating supports are each at the same distance from one another and therefore adjustments with regard to the desired length of the product stack are only possible through larger conversion measures. Also size adjustments regarding the height and width of the leaves require modifications to all separating supports.
  • a further disadvantage is that the known method only allows the individual product stacks to be subdivided, but not the product stacks subdivided in this way, for the purpose of further processing.
  • the invention is therefore based on the object of providing a method for producing defined stacks of folded or unfolded sheets or sheet-shaped objects which, even without conversion measures, enables separation and subsequent separation of even different sized stacks of products.
  • first parting plane defining the beginning of the stack and a second parting plane defining the end of the stack is carried out by successively moving the separating support into the cross-section of the stack transversely to the longitudinal extent of the base, and in each of the two formed in this way Separation levels each fully retract another support.
  • the method according to the invention works with only one separating support, no conversion measures are required to change the length of the product stack.
  • the length of the product stack is rather freely variable by choosing the point in time at which the separation support enters the stack cross-section for the second time and forms the second separation plane. It is also advantageous that the already divided product stack can be separated and fed to a subsequent processing by means of the two further supports.
  • a further development of the method provides that the separating support is inserted into the stack cross-section by means of a device under prestress. This makes it possible to move the separation support into the stack cross-section at high speed to form the separation planes and thus to reliably subdivide two product stacks.
  • the preloaded device is released by actuating a locking member.
  • the separation planes formed by the separation support are maintained by a transfer support that completely moves into the separation planes before the further supports are retracted.
  • the method has a greater scope in terms of time in the further processing of the product stack captured and transported by the two further supports.
  • the transfer support is retracted while the separating support and transfer support move parallel to the base at a stacking speed.
  • the retraction of each of the two further supports also takes place while the transfer support and the respective further support move parallel to the base at a stacking speed.
  • the invention further relates to a device for producing defined stacks of folded or unfolded sheets or sheet-like objects, with a feeding device which stores the individually fed sheets standing on a horizontal table and a separating support which can be moved in the longitudinal direction of the table to form a defined dividing plane between successive stacks.
  • the separating support and at least two further supports which can be moved in the longitudinal direction of the table independently of the movement of the separating support can be moved transversely until the stack cross section has been fully inserted are trained.
  • This device undergoes its further development in that the further supports can be moved horizontally to one another by means of a relative guide and the further supports and the relative guide are arranged to be movable on a horizontal main guide.
  • the separation support is preferably connected to the piston of a pressure cylinder, with a locking member taking over the locking of the separation support in its rest position.
  • the device also proposes that, in addition to the separating support and the two further supports, a transfer support is provided, which is also designed to be movable in the longitudinal direction of the table and to be fully retractable into the stack cross section.
  • This transfer support enables one Greater temporal independence between the movement of the separating support and the movement of the two further supports causing the product stack to be removed.
  • the transfer support is arranged on the side of the table opposite the separation support and the two further supports.
  • the table have a plurality of slots running in the longitudinal direction.
  • the transfer support and the two further supports are preferably constructed in the manner of a rake, the fingers of which are each arranged above or below the slots, while the fingers of the separation support which is likewise constructed in the manner of a rake are each arranged above or below the horizontal surfaces of the table.
  • the fingers of the transfer support are designed as U-shaped profiles in cross section, the opening of which is remote from the feed device.
  • the height of the table can be changed by means of first adjustment elements, and the width of the table, the separating support, the transfer support and the further supports can be changed by means of second adjustment elements.
  • the device shown in FIGS. 1 and 2 assembles sheets 1 or sheet-shaped objects, such as napkins, into larger stacks and then transports them to a downstream processing device, for example a packaging machine.
  • the finished cut and folded sheets 1 pass by means of a cylindrical transfer device 2 to a feed device 3 designed as a delivery cylinder, which strips the individual sheets 1 on a base designed as a table 4.
  • the sheets 1 held by the grippers (not shown) on the circumference of the feed device 3 are released immediately before reaching the table 4 and then moved by a swiveling racket 5 against a stack already placed on the table 4.
  • the newly fed sheet is therefore deposited on the back of the stack that has already been formed.
  • the racket 5 In order to give the racket 5 the necessary freedom of movement, it projects like a throat between individual disks of the feed device 3 designed as a delivery cylinder, as can be seen in FIG. After the last sheet has laid down on the stack, the racket 5 swings again back to its dashed starting position and maintains this until the next sheet, held on the circumference of the feed device 3, is almost down to the height of the table 4.
  • suitable adjustment elements 6 are provided.
  • a separating support 7 designed in the manner of a rake or a comb, which can be moved by means of a pressure cylinder 8 to just above the top of the table 4 and can be pulled back into its starting position shown in FIG. In this starting position, the separating support 7 is blocked by a locking member 9 operating in the manner of a pawl. The actuation of the locking member and thus the release of the separation support 7 takes place by means of a small pressure cylinder 10. A controlled movement of the separation support 7 parallel to the longitudinal extension of the table 4 is possible via a horizontal guide 11 by means of an actuating cylinder 12.
  • FIG. 2 shows that the individual fingers 16 of the transfer support 17 are designed as U-shaped profiles, the opening of which Feed device 3 is formed facing away.
  • the transfer support 17 can also be moved in the longitudinal direction by means of a horizontal guide 18. By means of a vertical actuating cylinder 19, the transfer support 17 can be moved from the position shown in FIG. 1 below the table 4 to an upper position shown in dashed lines on the left, in which the transfer support is located within the stack cross-section.
  • Figure 1 also shows that above the table 4 two further supports 22, 23 are arranged, each movable by means of a vertically acting adjusting cylinder 20, 21.
  • the two further supports 22, 23 can be moved from the upper position shown in FIG. 1 to a lower position just above the table 4.
  • the two further supports 22, 23 in this lower position, in which they are located within the stack cross-section, with their fingers 24, 25 exactly in the fingers 16 of the transfer support designed as U-shaped profiles 17 fit in.
  • the two supports 22, 23 can be moved together in the longitudinal direction via a further horizontal guide 26.
  • both supports 22, 23 are arranged on a support 27, which in turn is provided with a smaller longitudinal guide 28.
  • the actuating cylinder 20 of the front support 22 is firmly connected to the support 27, the actuating cylinder 21 of the rear support 23 can be adjusted relative to the support 27 by means of the longitudinal guide 28.
  • Another small actuating cylinder 29 is used for this purpose.
  • the separation support 7 In the starting position according to FIG. 3a, the separation support 7 is in the locked position above the already formed stack of sheets 1.
  • the pressure cylinder 8 stands for the vertical movement of the separation support 7 already under working pressure.
  • the locking member 9 releases the separating support 7, so that it descends at high speed to just above the table 4, as shown in FIG. 3b.
  • the separating support 7 As soon as the separating support 7 has reached its lower position, it moves in the longitudinal direction of the table 4 until the pivoting range of the racket 5 is cleared. The subsequent further movement of the separating support 7 takes place at the speed of stack formation, that is to say the speed at which sheets deposited on the table are transported further in the horizontal direction.
  • the transfer support 17 moves from below into the separation plane formed, the fingers 16 of the transfer support 17 passing between the fingers 13 of the separating support 7.
  • the separating support 7 is moved upward in the manner shown in FIG. 3c and returned to its starting position according to FIG. 3a.
  • the transfer support 17 is thus introduced in the method step according to FIG. 3c into the parting plane originally formed by the parting support 7 and now takes over the task of separating the preceding stack from the following one.
  • the separating support 7 and the transfer support 17 move at the same speed, namely the stacking speed.
  • separation support 7 and transfer support 17 can also assume a fixed transfer position for a short time.
  • the transfer support 17 according to FIG. 3e takes over the next parting plane, which has meanwhile been generated by the parting support 7.
  • This second or rear parting plane defines the end of the stack.
  • the rear support 23 has not yet performed any longitudinal movement, which is achieved by a movement of the small actuating cylinder 29 which is opposite to the movement along the horizontal guide 26.
  • the rear support 23 is also lowered and takes over the rear parting plane from the handover support 17.
  • the Transfer of the rear parting plane to the support 23 the support 23 and the transfer support 17 at the same horizontal speed.
  • both can also take a fixed handover position for a short time.
  • FIG. 3g shows the state immediately after the rear parting plane has been transferred to the rear support 23.
  • the front support 22 is moved forward at a high speed and the rear support 23 at an even higher speed, while the transfer support 17 continues to move at the normal stacking speed.
  • the movement speeds are indicated in FIGS. 3g and 3h by corresponding arrows.
  • the length of the stack is compressed to the desired length or the length required for further processing.
  • the stack thus separated is carried away at high speed. This is shown in Figure 3h.
  • the opening of the rear parting plane shown is possible because the fingers 25 of the rear support 23 can easily move out of the U-shaped fingers 16 of the transfer support 17.
  • the transfer support 17 forms the front stop and defines the front parting plane of the next stack. This next front parting plane is then taken over by the returning front support 22, so that the method is repeated starting with the state shown in FIG. 3d.
  • the parting planes are thus each formed by the separating support 7 moving down at high speed, then taken over by the transfer support 17 and finally transferred to one of the further supports 22, 23.
