Definitions

  • the invention relates to a control head for a suction roll, which is used for sucking and conveying and releasing and / or at the same time for processing sheets or blanks made of paper or other thin or sheet-like materials and comprises the features of the preamble of claim 1.
  • the invention comprises a method for controlling the negative pressure of the suction zone of the suction roll.
  • a control head for controlling the suction path of a suction roll which is rotatably mounted and with an end face on an at least one control channel end face of the control head slidably abuts and at least one end face and extending coaxially longitudinal channel for supplying transverse to the roll surface extending radial bores Has negative pressure / vacuum.
  • the invention is therefore still based on the object to provide measures by means of which the flow noise can be reduced to fast-running suction rolls. This can be avoided if necessary costly soundproofing measures.
  • the invention provides that the suction channel and the ventilation zone are arranged in the control head such that the cancellation of the negative pressure in the vacuum zone of the suction roll is already started when and / or before the generation of negative pressure is completed.
  • a suction roll 1 is freely rotatably mounted in a machine frame 2 by means of a shaft 3 and is with Help a gear 4 driven.
  • the suction roll 1 has at least one longitudinal channel 5, for example in the form of a longitudinal bore, from which transverse bores 6 extend in the respectively required number and shape and configuration to the surface 7 of the suction roll 1.
  • Each longitudinal channel 5 ends at the control head end in a suction opening 8.
  • This suction opening 8 is located in the one end face 9 of the suction roll 1.
  • the longitudinal channel 5 and the transverse bores 6 form a suction zone 10 in the suction roll. 1
  • the suction roll 1 With its end face 9, the suction roll 1 is slidably or non-contact and largely airtight to a control head 11, the suction roll side also has an end face 12.
  • the control head 11 is stationary and does not rotate.
  • a thread 15 and an adjusting nut 16 are used for exact adjustment of the end faces 9 and 12 of the suction roll 1 and the control head 11 to each other.
  • a suction line 17 is finally connected to the control head 11 such that a respective desired negative pressure in an arcuate suction channel 18 in the control head 11 prevails.
  • the suction channel 18 extends coaxially from the end face 12 in the interior of the control head 11 and according to the embodiment shown in the figures over an angular range.
  • the arrangement and the angular range of the arcuate suction channel 18 is further selected so that the axis of the longitudinal channel 5 in the suction roll 1 and thus also the axis of the frontal suction opening 8 of the longitudinal channel 5 with the suction channel 18 from the position of the incipient negative pressure as shown in FIGS 1 and 2 are aligned coaxially until the end of the negative pressure as shown in FIG.
  • the suction roller 1 moves with its suction opening 8 in the counterclockwise direction from the position shown in FIG. 2 in the position shown in FIG. 3, where there the suction port 8 a has almost completely left the suction channel 18. It occurs in front of a web 19 which limits the suction channel 18 in the direction of movement of the suction opening 8.
  • a ventilation zone 20 limits the web 19 on its side facing away from the suction channel 18.
  • an auxiliary bore 21 is provided according to the embodiment shown in FIGS. 1 to 5 a. It is located in the web 19 and serves to supply for the cancellation of the negative pressure in the suction and vacuum zone 10 of the suction roll 1 serving air from the atmospheric environment. This happens depending on the position of the auxiliary bore 21 in the web 19 before the end of the negative pressure generation or immediately with the completion of the vacuum generation, which can serve atmospheric air or compressed air for this purpose.
  • a valve 22 and a line 23 are provided according to the dashed or dash-dotted lines in Fig. 1, via which the auxiliary bore 21 can be supplied with atmospheric air or compressed air.
  • concrete auxiliary bore 21 can be - depending on their location in the web 19 - achieve that the cancellation of the negative pressure in the suction or vacuum zone 10 of the suction roller 1 begins, immediately when and / or before the cancellation of the negative pressure.
  • auxiliary bores By means of one or more such auxiliary bores, it is possible to generate states with different pressure differences in a targeted manner, and atmospheric air and / or negative pressure can be introduced into the suction roll in manifold form, so that optimum flow and noise conditions can be achieved.
  • the cross section of the auxiliary bore can be varied so that the volume flow is variable.
  • the auxiliary bore 21 is essentially a part of the aeration zone 20, so that a first partial supply with the vacuum / negative pressure canceling flow medium in the form of "intermediate air” can take place before the generation of vacuum / negative pressure ends and before a second ventilation of the Vacuum / negative pressure vacuum zone 10 is carried out with the help of the negative pressure completely reversible flow medium from the chamber-shaped ventilation zone 20 according to the embodiment.
  • This "intermediate air” is atmospheric air and / or compressed air.
  • auxiliary bore 21 2 to 5 a The representation of the cross section of the auxiliary bore 21 2 to 5 a is only an example. Instead of an auxiliary bore 21 which is very small in cross-section, it is also possible to provide a ventilation chamber which is clearly defined in terms of its shape and shape and which contributes to the generation of defined pressure states in the vacuum or suction zone 10 of the suction roll 1.
  • the free cross section of the auxiliary bore 21 is very small.
  • this is not mandatory.
  • the dimensions can basically be chosen differently.
  • an auxiliary bore also basically an intermediate chamber may be provided, which can be supplied with vacuum / compressed air or atmospheric air and is arranged so that the cancellation of the negative pressure in the vacuum zone of the suction roll is already started, if and / or before the generation vacuum is completed and before the aeration zone is reached.
