Definitions

  • the invention relates to a folding machine with at least one pair of knife shafts, the blade shafts are mounted in a working position parallel to each other between two spaced-apart side walls of the folding machine.
  • the folding rollers of a folding unit are preceded or adjusted by pairs of cutter shafts.
  • These are usually knife shaft pairs in which a blade shaft is equipped with upper blade tools and the other blade shaft with lower blade tools, which are arranged on a mounted on the blade shaft tool holder.
  • the knife shafts are equipped with appropriate tools depending on the requirements of the order.
  • a corresponding folding machine is disclosed for example in DE 30 25 239 C2.
  • the knife shafts are usually stored in the known folding machines on the side walls of the folding machine. For this reason, they can only be removed when the folding machine is at a standstill.
  • the knife shafts For this it is usually necessary to first pull out the folding pockets. Then, after loosening their attachment, the knife shafts must be lifted out over the side walls of the machine. Since the knife shafts usually have a very high weight, this work is very tedious. Finally, the blade shafts can only be adjusted accurately if they are installed in the folding machine. For this purpose, tools are mounted in the immediate vicinity of the knife shafts. These are e.g. Rulers with a printed measuring tape on which the position of the tool can be read.
  • a folding machine in which one or more entire folders, consisting of knife shafts, folding pocket and folding rollers preferred is moved by pivoting out of the folding machine to provide easy accessibility to the knife shafts and folding rollers. Since the entire folding unit must be moved out of the folding machine, the known construction is very expensive. In addition, it is not possible to preset only the blade shafts outside the folding machine.
  • the invention has for its object to provide a folding machine with structurally simple means that allow a quick change of the blade shafts in a simple manner.
  • the knife shafts are mounted in the cassette, which is displaceable by the side wall from the insertion position into the extended position, a change of the knife shafts without pulling out the folding pockets of the upstream folding unit is possible.
  • the cassette is arranged in a drawer which can be inserted and withdrawn through the side wall.
  • the cassette can be removed and a new cassette placed on the drawer. After inserting the drawer, the change of the knife shaft pair is completed.
  • the cassette has a drive-side end wall and a user-side end wall, which are arranged at a distance from each other and connected by a crossbar.
  • the knife shafts are mounted on the forehead by storage facilities.
  • the storage facilities at least one blade shaft for adjusting the gap between the blade shafts are adjustable.
  • This adjustment is part of the knife shaft cassette. The adjustment can be done outside the folding machine.
  • the drive-side bearing devices may be rotatably mounted in the drive-side end wall and pass therethrough.
  • An accurate adjustment of knife holders on the blade shafts can be achieved by providing a graduation on the shaft body of the blade shaft, which is preferably engraved.
  • the knife holder can be set on the blade shafts outside the machine, the operator can stand in front of the knife shaft cassette when changing tools so that no parallax error occurs.
  • the folding machine 10 shown in FIGS. 1 and 2 has a pocket folder with a folding pocket 12, which in the sheet running direction folding rollers 14, 16 are arranged downstream, which are mounted in a drive-side side wall 18 and a user-side side wall 20.
  • the folding rollers 14, 16 in the sheet running direction, a knife roller pair consisting of an upper cutter roller 22 and a lower cutter roller 24 downstream.
  • On the cutter rollers 22, 24 are arranged in the longitudinal direction at a uniform distance five knife holder 26, arranged on which not shown tools for cutting, cutting, perforating, crimping, etc. of the folding pocket 12 leaving bow.
  • the knife shafts 22, 24 are mounted in a cassette 28, whose configuration will be explained in more detail below.
  • the cassette 28 itself is arranged on a drawer 30, which is so far from the folding machine 10 can be pulled out through an opening in the user-side side wall 20 until the entire cassette 28 is outside the folding machine 10. This position is shown in Fig. 1.
  • Fig. 2 the position of the drawer 30 is shown, in which it is fully inserted into the folding machine 10.
  • the drawer 30 abuts with its drive-side end wall on the drive-side side wall 18.
  • the drawer 30 extends completely between the two side walls 18, 20.
  • the drawer 30 rests on a horizontal floor 32 which extends between the side walls 18, 20.
  • guide means (not shown) are provided to guide the drawer to make a straight line movement.
  • a guide for a drawer serve two three-part telescopic guides, which are interconnected by a drawer bottom and are arranged completely in the retracted state between the machine side walls.
  • the cassette 28 is inserted into the drawer 30.
  • the cassette 28 with the knife shafts 22, 24 arranged parallel to one another on it is shown in greater detail in FIGS. 3 to 5.
  • the cartridge 28 has a drive-side end wall 34 and a user-side end wall 36, which are interconnected by trusses 38, 40.
  • the two cutter shafts 22, 24 are rotatably mounted on the operator side in knife shaft bearings 42, 44, for example via thru axles or half shells.
  • the upper bearing 42 is slidable or rotatable about an eccentric point in a plane defined by the two shaft axes to allow adjustment of the gap between the two cutter shafts 22, 24.
  • the cutter shafts 22, 24 are rotatably supported by bearing devices 46, 48, wherein the bearing means 46, 48 are simultaneously formed as a rotary feedthrough and coupling element, which are rotatably connected to a drive element of the folding machine when the cassette 28 is inserted into the folding machine 10 becomes.
  • the storage devices 46, 48 are also displaceable in the plane which is spanned by the two shaft axes, wherein an adjusting element 50 allows a precise adjustment of the gap between the cutter shafts 22, 24.
  • the tool holders 26 are detachably mounted on the shaft body 23 of the cutter shafts 22, 24.
  • a precise positioning of the tool holder 26 on the cutter shafts 22, 24 is made possible by a graduation, as shown in Figs. 6 and 7.
  • As a graduation 52 a vernier is engraved in the surface of the shaft body 23 in the longitudinal direction of the cutter shafts 22, 24. Due to the precise scale 52 directly on the blade shaft 22, 24, it is possible to attach a tool holder 26 precisely on the blade shaft 22, 24.
  • the accuracy of the attachment is further enhanced by allowing an operator to attach the tool holders 26 to the knife shafts 22, 24 outside the folder 10. This avoids a parallax error.
