Definitions

  • the invention relates to an apparatus for controlling the position and/or at least one dimension of printed products, which are conveyed while positioned flat in a conveyed flow and are composed of several signatures or individual printed sheets, with the aid of a conveying device for transporting the printed products and at least one sensor that is directed toward the printed products and is connected to a computer-supported control.
  • Deviations from a predetermined position can cause the printed product to differ impermissibly from the specified dimensions and/or an angle. It should furthermore be possible to check the length, width, or thickness of printed products without influencing the production speed.
  • Japanese patent document JP 2005-62127A discloses an apparatus in which printed products are supplied with the aid of a conveying device to an angular measuring frame. Several sensors are used to respectively check whether the printed product supplied to the measuring frame exceeds or falls below a predetermined width or length. It can furthermore be checked whether the printed product is right-angled. Printed products which do not have the predetermined dimensions can thus be transferred out.
  • this apparatus is not suitable for high capacity processing and larger series, since the individual printed products must be stopped at the measuring frame and must then be accelerated once more.
  • German patent document DE 102 47 455 A discloses an apparatus for adjusting the position of the side edges of a continuous web, wherein sensors are provided for detecting the desired position of the side edges.
  • this apparatus is not suitable for processing individual printed products, such as is the case for gathering and wire-stitching machines.
  • an apparatus for controlling at least one of a position or at least one dimension of printed products conveyed while positioned flat in a conveyed flow comprising: a conveying device to transport the printed products; at least one sensor directed toward an edge of the printed products and comprising one of a line sensor or area sensor; and a computer-supported control coupled to receive an output signal of the at least one sensor.
  • Such an apparatus not only permits the detection of the printed products at one point, as has been the case so far, but allows the detection over a region.
  • a line-shaped region of the printed products is detected transverse to one edge of the printed products.
  • Measurements of this type in particular make it possible to control a drive, for example for adjusting a position.
  • Suitable line sensors and area sensors are already known and, in particular, allow an analog detection of the position of a product edge.
  • the detection of the printed products with the sensor preferably occurs while the products are transported in a horizontal plane with a conveying device.
  • the printed products can also be detected by the sensor in a different position, for example while in a plane that is slanted transverse to the conveying direction or while in a suspended position.
  • Two or more sensors can also be used in place of a single sensor to simultaneously detect a printed product.
  • opposite-arranged edges of a printed product can be detected with two sensors, thus making it possible to check the course of these two edges and, in particular, check whether the edges are parallel to each other.
  • a spacing between these two edges, that corresponds to either the length or the width of a printed product can be determined. If the sensors are arranged to be displaceable, it is possible to detect and/or measure printed products belonging to a broad format range.
  • the sensor is preferably an optical sensor, wherein non-optical sensors, such as electronic sensors, are conceivable as well.
  • US 2003/0072499 A1 and US 2005/0239621 A1 disclose suitable optical sensors while electronic sensors are disclosed in DE 19941728 A1 and are commercially available as ZADM 034 at Baumer Ltd.
  • the leading edge of a printed product is detected with the sensor, thus making it possible to control the position of the printed products, for example for the trimming of the trailing edge inside a cutting apparatus.
  • the sensor in particular is used to detect the position of the printed product and control the drive for the conveying device based on the direct measurement taken at the printed product. This permits an especially precise positioning of the printed products for a processing, for example, for the step of cutting, punching, addressing, gluing and the like.
  • the apparatus is particularly suitable for use with a gathering and wire-stitching machine, an inserting machine, a perfect binder or a collating machine.
  • the apparatus can conceivably also be used with other machines for processing printed products, for example machines for producing newspapers, magazines, books, booklets and the like.
  • a method for controlling at least one of a position or at least one dimension of printed products conveyed while positioned flat in a conveyed flow comprising: transporting the printed products with a conveying device; directing at least one line sensor or area sensor toward the printed products to sense an edge of a respective one of the printed products to produce an output signal corresponding to said edge; and outputting the output signal to a computer-supported control.

  • a section 17 of the stationary printed product 6 is cut off while the product is positioned between an up- and down moving upper blade 15 and a stationary lower blade 16 in order to obtain the desired width 30 for the printed products 6 .

  • Two spaced-apart sensors 2 which can be embodied identically, are arranged above the conveying device 13 . These sensors 2 are so-called line sensors or also area sensors, which may be light-sensitive and extend over a predetermined length. In this case, the sensors extend parallel to the transporting direction 22 for the conveying device 13 , which forms a component of the cutting machine 7 .
  • the two sensors 2 are arranged in so that they can simultaneously detect the respective leading edge 8 of a printed product 6 . Since the sensors 2 extend over a specific length in the conveying direction 22 , all positions of the leading edge 8 can be detected within this section.
  • FIG. 1 b also shows the printed products 6 ′, 6 ′′ with the leading edges 8 ′, 8 ′′ and the side edges 9 ′, 9 ′′, which respectively occupy during the processing a position that differs from the position of the printed product 6 .
  • the two sensors 2 respectively form a light curtain 2 b , which in part impinges on the top of the respective printed product 6 , 6 ′, 6 ′′ and in part also on a reflector 2 a .
  • the light rays impinging on the reflector 2 a are reflected back to the sensor 2 .
  • the measuring values are supplied via corresponding signals to an automatic controller 3 .
  • This automatic controller 3 is connected to a control 4 and the drive 5 .
  • the conveying device 13 , the two sensors 2 , the automatic controller 3 and the drive 5 jointly form a control loop, which makes it possible to precisely control the transport of the respective printed products 6 , 6 ′, 6 ′′.
  • the dimensions for the printed products 6 ′, 6 ′′ can differ from the desired value as a result of the cut made to the trailing edge 10 .
  • the width 30 can be either too small or too large and/or the leading edge 8 and the trailing edge 10 are not parallel to each other.
  • Printed products 6 ′, 6 ′′ of this type can be removed from the conveyed flow, for example with the aid of a diverter 18 that is connected to the control 4 and is positioned downstream of the conveying device 13 . As a result, it is ensured that only printed products 6 that are within a selectable tolerance range during the processing are transferred to a downstream arranged transporting apparatus 20 and are conveyed further in a transporting direction 23 .
