Definitions
- the present invention relates to a device for generating a shingled stream with an adjustable shingled stream thickness.
- the present invention is concerned with a sheet stack feeder device which comprises a sheet guiding device from which sheets in the form of a shingled stream with an adjustable shingled stream thickness can be drawn off.
- a sheet stack feeder usually comprises a sheet guiding device for receiving a larger stack of sheets, as well as a device for generating a shingled stream which pulls stacks or scales like sheets from the underside of the sheet stack held in the sheet guiding device and the shingled stream thus formed Intermediate compartment feeds, from which individual sheets are drawn off by a separating device for subsequent processing.
- a shingled stream generating device is therefore usually part of a two-stage separation principle, in which a shingled stream is first formed from a large stack of sheets, which stream is ultimately converted into a paper stream of individual sheets.
- such a shingled stream generating device has a transport roller, which engages with a sheet stack on the underside of the entire stack, which is held by the sheet guiding device, and transports this sheet stack in the direction of the intermediate compartment.
- a stack height limiting device is typically arranged in the region of the lower edge of the total stack, which is typically formed from a rotating roller and a fixed roller arranged at a fixed distance therefrom, the clear distance of which is the height from the bottom of the Total stack subtracted borders.
- the scale flow generated with such a device is often irregular with regard to the scale spacing and the scale flow thickness.
- FIG. 1 shows a feeder with a feeder stack, from which the sheets are removed by a suction device and fed to the printing press via a feeder table and alignment devices.
- a transport roller is provided in front of the feed table and can be lifted off by a corresponding control so that a new sheet can be inserted in each case. This transport roller is resiliently pressed against a lower roller. The distance between these rolls corresponds to the thickness of the sheets in between and is measured by a displacement sensor.
- Correspondingly weighted Averaged output signals of the displacement sensor are compared with a stored reference value in order to be able to identify double and missing sheets.
- the present invention is based on the object of creating a device for generating a shingled stream with an adjustable shingled stream thickness.
- the device according to the invention for generating a shingled stream comprises a sheet guiding device for receiving a stack of sheets, two mutually independent transport devices and a shingled stream thickness detection device.
- One of the two transport devices has an optionally actuable or controllable drive.
- This transport device engages with the underside of the sheet stack and is arranged with respect to the sheet stack, preferably in the middle of the bottom sheet of a slightly inclined sheet stack, in such a way that the sheet stack has at least a first part of its weight, preferably more than 30% its weight, weighs on you.
- the second transport device is arranged behind the first transport device in the sheet current direction.
- the location of the second transport device is preferably at the edge of the lowermost sheet of the stack of sheets lying in the sheet flow direction of the first transport device.
- the second transport device is preferably driven continuously, that is to say continuously during operation of the shingled electricity generating device.
- the location of this second transport device in relation to the sheet stack is selected such that the sheet stack only loads the second transport device with such a small second part of its weight, or does not bear it at all, such that when the second transport device is actuated and the actuation is not actuated
- the first transport device only transports sheets that have already been pulled out of the stack of sheets by the first transport device.
- the said shingled stream thickness detection device which detects the thickness of the shingled stream and switches the drive of the first transport device on and off as a function of the detected shingled stream thickness or in terms of its speed controls.
- the shingled stream thickness detection device responds to this and, according to a preferred embodiment of the invention, switches off the drive of the first transport device, whereupon the second transport device only conveys only those partial stacks or sheds that the first transport device has already removed from the overall stack. had pulled. This leads to an extension of the scale flow, an increase in the scale spacing and thus a decrease in the scale flow thickness until the scale flow thickness detection device detects that the current scale flow thickness falls below the maximum value mentioned and then actuates the first transport device again.
- Sheet stack feeder with a preferred embodiment of the device for generating the shingled stream.
- a sheet stack feeder which is designated in its entirety by the reference number 1 in the single figure, comprises as main components a sheet guiding device 2 for receiving a stack 3 of sheets, an intermediate compartment 4, a scale-forming device 5 for stack-like or scale-like pulling-out of sheets from the sheet Underside of the stack 3 accommodated in the sheet guiding device 2 and for introducing it into the intermediate compartment 4 in a first direction of movement, as well as a sheet separating device 6 for individually pulling out the bottom sheet from the intermediate compartment 4 in a direction essentially opposite to the first direction of movement second direction of movement.
- the scale formation device 5 has a first, second and third transport roller in the bottom region 7 of the sheet guiding device 2.
- the first transport roller 8 is located essentially in the center below the stack 3, so that the greatest part of the weight force of the stack 3 is loaded on it. While the second and third transport rollers 9, 10 essentially during the operation of the sheet pile feeder are continuously driven, the drive of the first transport roller 8 can be switched off by a clutch (not shown) depending on a control system to be explained below.
- a round belt 11, which is also driven by the third transport roller 10, has a first belt section 12, which extends from the first to the third transport roller 8, 10 along the bottom region 7 of the sheet guiding device 2, and a second belt section 13, which extends inside of the intermediate compartment 4, starting from the driven third transport roller 10, is inclined downward and extends to a separating point 14 of the sheet separating device 6.
- the separation point 14 is formed by the approach area between a fixed separation roller 15 and a removal roller 16, which are arranged at the separation point 14 at such a small distance from one another that the removal roller 16 always has only a single sheet between it and the separating roller 15 can pull through.
- a non-driven roller 17 is movably mounted in the vertical direction.
- the vertical position of the roller 17 is detected by a sensor (not shown) which responds when a maximum value of the thickness of the shingled stream moving between the roller 17 and the third transport roller 10 is exceeded, whereupon the clutch of the first transport roller 8 stops it becomes.
- the bottom region 18 of the intermediate compartment 4 is arranged so that it slopes downwards in the direction of the separating point 14, as a result of which the leaves located in the intermediate compartment 4 rest against the second belt section 13 of the round belt 11 with their edge on the left in the figure.
- a friction belt 20 extending parallel to the bottom region is guided over three guide rollers 21 to 23 and a drive roller 24, the friction belt 20 being driven in such a way that the bottom sheet lying on it within the intermediate compartment 4 is closed the separation point 14 is pushed.
- the first transport roller 8 represents the first transport device. It should be noted that, for the purposes of the invention, the first transport roller can also be formed by other conveying means, such as a separate belt drive.
- the second transport device is formed by two continuously driven transport rollers 9, 10 and the first belt conveying section 12.
- other, preferably continuously running, conveying means are possible, as far as they are designed and arranged such that when the second transport device is operated alone and without the first transport device being operated, only sheets that are already being transported by the first transport device are transported by the second transport device from the stack of sheets that the Sheet guide device holds, have been pulled out.
