The invention concerns a method for separate and aerate stacks of sheet-shaped material, in particular piles of paper, in which the sheets of sheets of each one of the hands of the material stacking move each other in your hand and then deposited.

The invention also concerns a device to separate and aerate stacks of sheet-shaped material, in particular of paper stacks, composed of at least elements to separate from each other the sheet of sheets of each of the hands of stacking material and to aerate the paper hand before deposit it, and transport elements to carry the hand on a storage device.

For the reworking of particular batteries of printed papers, for example in a guillotine machine, in order to cut large hands into smaller copies or for example during the binding process, to make the edges work of the books, the sheets of hands must be perfectly aligned with each other. The use of vibration devices in which an alignment of Hands on two sides. So that alignment can be accelerated in the vibration device the hands were eaten before - by general rule is done manually - in order to get air between sheets of sheets and separate them from each other.

From document DE 32 19 693.8 it is already known a device for the formation of stacks of sheet pieces of sheets to be made, in particular of paper sheets, with which is possible an automatic deployment. The device is composed substantially of a conveyor that carries paper hands from a supply stack and deposits them on the table of a vibrating device. Present a band bottom rotary and a deployment station where they are provided a lower roller and another upper roller both with drive forming a variable pitch slot for hands of paper. The speeds on the periphery of both rollers are adjust to be different.

When you put your paper hand through from the deployment station a mutual displacement occurs between the sheets of hand. Through the different setting of the rotation speeds of the rollers is further reinforced the deployment.

Additionally, through air nozzles that are arranged at the delivery end of the conveyor is air blows between the sheets of individual sheets.

This device is constructively expensive and in the practice is not used with advantage since the specifications of hand blades move during transport in such a way They wrinkle.

Therefore, the object of the invention is configure in such a way a procedure of the type mentioned to principle that is possible to get the sheets of sheets of a hand automatically separate from each other easily and economic so that the process can be minimized in time of vibration

It is also the task of the invention to develop and improve a device of the type explained at the beginning that in a way constructively simple and automatic allow displacement sure of the sheets of sheets with each other and an aeration of the hands during transport and deposition to and over the vibration device

According to the invention, regarding the procedure the task is solved by the characteristics of the claim 1.

According to this procedure according to the invention aerated in a technologically simple way automatic individual hands and the displacement of sheets of sheets inside each of the hands. With that the following work process is substantially shortened consisting of a perfect alignment of the hands. Also they successive work processes such as the guillotinates of the hands take place optimally since you can reduce the machine waiting times due to the long processes of vibration.

In addition, automated process development leads to substantial work relief for the user since this one no longer has to take from the supply stack manually large and heavy paper hands to arch in order to air them and open the sheets.

According to an advantageous configuration of the procedure according to the invention, the hand is grasped by a squeeze device and the squeeze device drag your hand by a guiding element tilted down through the Hall. Immediately after the passage of the clamping device through the aisle the top of the type device pincer is deposited on the hand, with which the individual leaves can be separated from each other during the next step of the hand. TO then the hand is deposited in the device storage.

The clamping device guarantees by a part that the sheet of sheets moves with each other and on the other hand It serves as a means of transport and support.

According to the procedure, the aisle size can be set variable and can be adjusted to the size of the clamping device installed. Because the clamping device can grab the hand during the step to through the hallway this allows you not to have to mount any another means of transport to transport the hand towards the aisle. This translates positively into costs and simplifies the course. of process.

It can also be advantageous if the hands are can deposit in a situation subject to both sides in the storage device and fastener unlocked immediately during the deposition process or immediately after.

On the one hand the hand is held by the clamping device and on the other hand by the top and the lower part of the device in the form of pincers. In this way it can prevent that during the deposition process the sheets of sheets adhere back to each other in an unwanted way.

According to another procedure configuration according to the invention after transport through the aisle of the pincer type device the hand is deposited in the form deployed

Also in that way the hand can be carried from advantageous mode for example to a vibration machine and in it place the sheet of individual sheets in the correct position.

In accordance with the invention, it is provided in addition to at least the top or bottom of the Pincer-shaped device are provided with drive.

This is for the transport of a hand not Holds up to the storage device.

It is also advantageous for the hand to be taken from the material stacking by means of a collection unit and transport to the guiding element or over the guiding element Towards the hall.

With it the to separate and aerate stacks of sheet-shaped material can be produced completely automated, which has the consequence of saving time and A simplification of work.

For the rest, from the point of view of the arrangement and alignment the task of the invention is solved by the features of claim 6.

The device according to the invention for separate and aerate stacks of sheet-shaped material is structured in a constructively simple way and allows the displacement and rapid separation of sheet sheets of a paper hand. With the constructive structure of the device it is achieved that the sheets of sheets cannot be stacked again each other until deposition in the collection unit. By consequently the perfect alignment of the hands can occur in a short time, for example in a vibration machine.

According to an advantageous embodiment and constructively simple device according to the invention the guiding element and the bottom of the device are configured in the form of a roller.

With it the hand, which is transported resting on the bottom and on which the element is supported roller-shaped upper acquires a wavy type shape that leads to the displacement of the sheets of sheets within the hand.

According to the invention it is provided that the top and bottom of the device in the form of pliers are arranged parallel one above the other and are set to rotate in opposite directions.

This also helps the process of displacement of the sheets of sheets inside the hand.

The bottom can also be configured from advantageous form for example in band form according to each execution concrete constructive

If the bottom has a larger diameter that the top and is made of a soft material that helps to the process of separating each other from the sheets of sheets of a hand.

According to the invention it is also advantageously provided that at least the top or the bottom part has a drive and both sides have Different rotation speeds.

This device configuration according to the invention helps and reinforces the breakdown of sheet sheets within a hand and consequently the aeration of the hand.

When the bottom is equipped with a coating or is made of a material that has a elastic surface softer than that of the hand prevents it from cause damage due to compression forces excessively high on the hand or on the sheets of sheets.

Another embodiment according to the invention Provide that the clamping device is configured as a pincer of tightening and can move in such a way that after tightening from the hand on one side the drag on the guiding element to and through the aisle to the storage device and deposit it there.

This achieves that the original form of the hand sheet folds remain substantially standing and shorten the following processes for hand positioning stacked each other.

Otherwise according to the invention is provided that the storage device is a machine vibration and that the device forms a unit with the machine vibration.

It is important that the route between the separation device and the aeration device be the most short possible, so that the sheets of sheets especially thick and heavy can not adhere back to each other before the deposition what would result in the process of positioning or the vibration process became more difficult or that these processes could not be executed with the proper quality. The following guillotining processes would also be then executed with reduced quality. Therefore it is advantageous that the two devices form a single unit.

To help the process of separation of hands are also provided that in the device in the form of pincers are arranged at least one air nozzle that blows air between the sheets of individual leaves of the hands.

To facilitate the work and for the execution Fully automated process is planned for the hand transport from the stacking of material to the guiding element or on the guiding element towards the corridor a pickup unit is arranged.

The invention is described below with greater detail with the help of an example of execution in which the device according to the invention forms a unit with an automaton vibrator. The corresponding drawings show:

Figure 1 a sectional representation of the vibrating automaton with the device according to the invention and with a clamping device for holding hands by one side seen laterally, and

Figures 2 to 5 the schematic representation of the individual phases of the process after the tightening of a hand.

According to figure 1 the device according to the invention for separating and aerating stacks 1 of shaped material of sheets, in particular piles of paper, is composed substantially by a lifting platform 2 on which it is located the stacking 1 of material, in this case in the form of a stack of paper to be guillotined in a machine guillotine, and that is configured to be adjusted in vertical, by a device 3 and by the automaton 4 vibrator attached with the.

The collection unit that has not been represented in the drawings is the one that is responsible for transporting each of the hands 5 of stack 1 of paper to guide element 6 or transport on the guide roller 6 towards the passage 7 of the pincer-shaped device 8, configured as a pincer rollers

The guiding element 6 is configured as input roller, which can rotate around its axis longitudinal and can be moved vertically. This way it is possible to adjust different weights of hands 5 and you can regulate the separation between the upper and lower parts 10, 11 of the pincer 8 of rollers.

The 5 individual hands are rising from the stack 1 of paper by means of a guillotine unit 9 and they capture and transport by the capture unit.

The pincer-shaped device 8 is composed of two parts arranged parallel and spaced one by on top of the other, fixed on a frame, the upper part 10 in pincer shape that can be moved vertically and that is set as rotary around its longitudinal axis and the lower part 11 which is also configured in the form of a pincer and as rotating around its longitudinal axis and whose sense of rotation is contrary to the direction of rotation of the upper part 10. He pliers-shaped device 8 is arranged with a separation default to guide element 6. Bottom 11 it also has such a vertical distance to the guiding element 6 that hand 5, which passes through hall 7 coming from the guiding element 6 has to be transported at an angle tilted down.

In the drawings the upper parts 10, 11 and lower have equal diameters. However, to help the hand deployment can be advantageous that the bottom part 11 present a diameter larger than the upper part 10. Besides, the bottom part 11 should be made of an elastic material and more soft, or at least have an elastic surface to avoid hand damage For the same reasons the surface of the part Bottom must have sliding properties.

In the execution example, a clamping device 12 for transporting the hand 5 from the guiding element 6 through the passage 7 to the device 4 Storage configured as a vibrating automaton.

Document DE 32 19 693 A1 describes the known clamping device 12 for catching a hand 5 by clamp 13, which according to the invention also It has to be installed. Therefore this part of the device will not be explained in more detail.

Similarly, the 4 vibrator automatons are known in themselves, which will not be explained here with greater detail.

To help the process of separating from each other the sheets 14 of individual sheets of a hand 5 in part 11 an air nozzle (not shown in the drawing) that to facilitate the separation of the sheets additionally air blows between said sheets 14 of sheets.

The course of the process and the mode of operation of the device to separate and aerate the paper stacks are described below with the help of figures 2 to 6.

The lifting platform 2 carries the stack 1 of paper that is composed of sheets 14 of individual sheets printed and large area by vertical movement up to a position in which the guillotine unit 9 first raise one hand 5 of paper, the pickup unit takes hand 5 of paper and can be deposited on the guiding element 6. The clamp 13 tightens through aisle 7 of the pincer 8 of rollers and holds hand 5 of paper on one side.

After grabbing and squeezing hand 5 by the pincer 13 of hand squeeze 5 is dragged over the roller 6 bending in the direction of the lower part 11 of the pliers 8 of rollers arranged at a distance and below the roller 6 bending With this, the hand 5 acquires a wavy shape. Hand 5 It is dragged downward. This way you can avoid damage to sheets 14 of sheets.

The upper part 10 of the roller pliers 8 is set to be able to scroll vertically and - as soon as the clamp 13 has crossed the aisle 7 again between the upper and lower parts 10, 11 - is deposited on the hand 5. This achieves that the sheets 14 of the leaves of the hand 5 move each other within their position. At the same time the 14 sheets of individual sheets are separated from each other and aerated. The farther the hand 5 is dragged through the passage 7 so much the greater the distance between the sheets 14 of individual sheets hand in hand 5.

Because the upper parts 10, 11 and lower turn in opposite directions you get another offset more than 14 sheets of sheet to each other.

The roller pliers 8 is arranged in such a way. so that after crossing the corridor 7 the hand 5 is deposited  directly on the vibrating table 15 of automaton 4 vibrator.

It is also possible to configure pincer 8 of rollers so that it can move horizontally, which can be transferred to a predetermined position on table 15 vibratory

Figures 2 to 5 illustrate the stages individual process or transport processes.

Figure 2 shows hand tightening 5 by means of the clamp 13 of tightening.

Figure 3 illustrates the process of dragging the hand 5 by means of the pincer 13 tightening on the roller 6 bending in the direction of the lower part 11 of the pliers 8 of rollers In this case, the clamp 13 moves both in horizontal as well as vertical. Sheet 14 located in the highest part it remains in its position while the other sheets 14 of sheets move with each other.

Figure 4 illustrates that the upper part 10 is supported on the hand 5 which causes the displacement of the sheets 14 of sheets together and prevents the return of the sheets 14 sheets of hand 5 to their positions. The direction of rotation contrary to the upper and lower parts 10, 11 help the process of displacement. The continuous transport of hand 5 through the 8 pincer rollers holding the clamp on one side causes the separation of the sheets 14 of sheets from each other and the aeration of the hand 5. After delivery to the vibrating automatons you can line up quickly and accurately.

To avoid damage, particularly in the specifications 14 of sheets that are located directly on the parts 10, 11 upper or lower is provided that at least the lower part 11 is provided with an elastic coating that is softer hand 5.

In particular, by separating and aerating hands 5 of small format it is possible to completely dispense with the use of device 12 tighten and configure the upper parts 10, 11 and / or lower of the pincer 8 of rollers equipped with drive. Hands 5 are carried by means of the pickup unit above from the roller 1 bending towards the aisle 7 and from there it transport, for example, to the automatons 4 vibrators, arriving also to the displacement and separation of the sheets 5 of leaves. The deposition on the vibrating table 15 takes place in this case in deployed form.

A combination of the two devices and the two procedures, that is, a partial use of the device 12 of tightening, for example to transport the hand 5 towards the pliers 8 of rollers, could also be used with advantage in certain application cases.

Obviously, the device according to the invention can also be used separately, that is, without Direct connection with the 4 vibrators automatons.
