Definitions
- the invention relates to a device and a method for stacking sheets, in particular of shingled supplied sheets of paper or cardboard on pallets, according to the Preamble of claims 1 and 4.
- the storage platform is loaded with the full pallet Lowered floor area. After the full pallet has been removed and a new one has been placed empty pallet, it is raised again to just below the feed level. So that the feed of sheets is not interrupted when changing stacks devices with an auxiliary stacking platform are known, which during the Removal of the finished stack carries the forming stack. The empty pallets are then moved to just below the auxiliary stacking platform and taken over the partial stack that has formed on the auxiliary stack platform.
- a stacking device in which the control of the The storage platform is lowered by means of a light button on the inlet side is arranged in front of the stack area and scans the stack height.
- Document EP-A-0 211 996 discloses a generic stacking device in which three optical sensors vertically one above the other next to the storage platform are arranged, which are all active in operation.
- the individual sensors are with one Distance of 10 - 20 mm, 20 - 40 mm and 40 - 60 mm below the upper end of the Arranged feeder and serve the lowering speed of the storage platform to control.
- a stacking device in which at the beginning of the Stacking area laterally five initiators arranged vertically one above the other at a height in which the storage platform is located when a stack change is carried out shall be.
- the initiators can be activated individually and release a braking device to stop the supplied sheet flow if the storage platform has reached this position due to bulges in the arches, although the preset Number of sheets to be filed has not been reached.
- the invention has for its object to a generic stacking device improve that the drop height of the arches easily to different Values can be set.
- At least three optical sensors for the top of the stack are vertical arranged one above the other, which can be activated separately. Two selected each Sensors determine the range of the maximum drop height deviation and enable it such a control of the storage platform so that an upper maximum value is not exceeded and a lower minimum value is not fallen below.
- the embodiment described below is used for stacking continuously Paper sheets 1 conveyed in scale form following a cross cutting machine.
- the sheets 1 are the stacking area by a belt conveyor trained feeder 2 fed at a height above the maximum Stack height is arranged above the floor.
- the stacks 3 are on pallets 4 formed, which are placed on a storage platform 5.
- the storage platform 5 is suspended in the frame 6 of the stacking device on pull chains 8. You can use the Pull chains 8 from the hall area to the area of the feed level 7 of the sheets 1 be raised and lowered.
- the stacking device has the Known elements for a precise storage of the sheets 1 on the stack 3 on: A bulletin board 9 for the sheet leading edges and side shaking plates 10 that on the longitudinal edges of the sheet act.
- FIG. 3 The area of the ejection section is shown in FIG. 3 shown enlarged.
- the Feed plane arranged vertically downwardly extending plate 12 which the Stacking area limited on the inlet side.
- the sheet trailing edges are on the plate 12 aligned.
- the plate 12 has cutouts in the ejection rollers 13 are mounted together with in the sheet running direction blowing blow nozzles 14 a safe transport of the sheets 1 in the stacking area guarantee.
- the device for stack height scanning consists of a box-shaped housing 16, in the front of the stack area facing at least three, in Embodiment five optical sensors 17 are arranged vertically one above the other. 17 reflection light sensors are preferably used as optical sensors, at which light transmitter and light receiver are in a housing (housing 15).
- the vertical distance between two sensors 17 is a maximum of 20 mm, preferably between 5 mm and 10 mm, in the present example 7.5 mm.
- the top sensor 17 is a short distance below the feed level, the distance is sufficiently large to prevent the upward movement of the platform 5 to be able to stop that the top of the stack remains below the feed level 7.
- the vertical position of the top sensor 17 is therefore chosen to be independent the top of the stack can be controlled from the sheet material to be stacked that it does not fall below the desired minimum distance from the feed plane 7.
- the top sensor 17 is 10 mm below the Feed level 7.
- the sensors 17 are offset in two vertical lines arranged so that the desired small vertical distance between two sensors 17th from each other.
- the signal lines 18 are in the housing 15, the to a control device, not shown, for controlling the vertical movement of the Storage platform 5 is connected.
- two of the five sensors 17 are activated the rest are inactive.
- the upper of the two active sensors 17 determines the minimum distance of the top of the stack from the feed level 7, the lower active Sensor 17 the maximum distance.
- the vertical position of the top of the stack becomes controlled by a vertical movement of the storage platform 5 so that they in essentially in the desired vertical range between the two active ones Sensors 17 is held.
- the control is advantageously carried out via a Two-point control, one if the upper position is exceeded Lowering movement and when falling below the lower position one Raising movement of the storage platform 5 triggers.
- the two corresponding sensors 17 are activated.
- three sensors 17 allow both the minimum head and the control range the fall height to two different values.
- five sensors as in the exemplary embodiment, is a multitude of possibilities given the drop height depending on the type by activating two sensors 17 in one Control area in which a trouble-free storage of the sheets 1 is possible. It is thus not necessary, the sensors 17 scanning the stack height at a Variety of changes to adjust. You only need the two matching ones Sensors 17 to be activated.
