Definitions

  • the present invention relates to a loading and loading station for tubular workpieces for a pipe cutting machine.
  • pipe cutting machines are used to cut long pipes into pipe pieces with shorter dimensions, in which a bearing is provided for receiving the pipes to be cut.
  • This bearing usually has an inclined floor, which enables the pipes to be fed to guide tracks for the individual feeding of the pipe.
  • the guideways are of considerable overall length and enable the pipes to be cut to be fed to a cutting station in which the cutting tool and devices for removing the cut pipe pieces are provided.
  • levers and rods are provided in order to enable the supply of a single pipe from the pipe store to the guide tracks for the pipe.
  • the pipe to be cut is in an automatically centering and driven clamping device or a similar device for performing a rotary movement during the Cutting process z.
  • the pipe to be separated is stored on roller conveyors. These devices have the disadvantage that the tube is moved forward by a sliding movement during the feed movement. As a result, there is a risk that the outer surface of the pipe will be damaged.
  • the known machines also have adjustment devices, the operation of which is time-consuming and complicated. With these devices it is possible to switch from pipes with a certain diameter to pipes with a different diameter. These adjustment processes become even more complex and difficult if there is a need to keep the position of the central axis of the tubes in the same position with a changing diameter. The difficulties that arise are due to the fact that when the tube diameter changes, a new adjustment of the various moving parts of the loading station is necessary.
  • the object of the above invention is to design a loading and loading station in such a way that the setting operations of the various movable components of the station can be carried out at a central point using a single actuating device and the tube longitudinal axis is always kept in the same position even with changing tube diameters. It is also an object of the invention to design a loading and loading station of the type mentioned in such a way that the pipe to be separated can be fed properly without the risk of damage to the outer surface of the pipe.
  • the loading and loading station With the loading and loading station according to the invention, considerable advantages can be achieved. This enables the possibility of a synchronized movement sequence for the various movable components of the device when changing from a pipe diameter to another diameter. This setting is possible in a trouble-free manner, since the moving components are kinematically linked to each other.
  • the provision of a centrally arranged control or drive device makes it possible to automatically and quickly adjust the machine's settings when the tube diameter changes, for example to be carried out using a drive motor.
  • the drive motor can advantageously be designed as a controllable motor which can be controlled via previously stored values, for example via an NC unit of the machine.
  • Another advantage of the loading and loading device according to the invention can be seen in the use of a limited number of different components. These components can be easily manufactured and have a safe function.
  • the pipe to be cut is now fed via adjustable bearings, which are provided with rollable balls, for example. The rotation and feed movement of the pipes to be cut takes place without damaging the outer surfaces of the pipes
  • the loading and loading station for the tubes is identified as a whole by 1.
  • This station 1 is part of a pipe cutting machine (not shown) which has a device for rotating the pipe by means of a centering chuck.
  • the loading and loading station 1 is assigned a material store for receiving the pipes 2 to be cut.
  • the bearing is shown schematically and labeled 3 and has an inclined base 4 on which an automatic feeding of the tubes 2 is ensured.
  • the entry into the loading and loading station 1 of the individual tubes 2 is adjusted via yoke-like arms 5. Only one of these arms is shown.
  • the yoke-like arms have a movable arm 6 and an arm 7 for limiting the passage height 7.
  • the flow opening (H) is only a little dimensioned larger than the diameter of the tubes 2 to be cut.
  • the pipe 2 arranged in the front in the pipe storage 3 is held in a waiting position by a movable stop 8. This attack will be described in more detail below.
  • the pipe 2 to be cut is supported on two strip-shaped longitudinal guides 9 and 10.
  • the guides 9, 10 extend in the longitudinal direction of the loading and loading device and are arranged in a V-shape at an angle ⁇ between the axes A and B.
  • the angle ⁇ is advantageously 60 ° to the vertical.
  • the guides 9 and 10 are connected to the bearing arms 13.
  • the bearing arms 13 each have one window-like recess 14, which are movably arranged on a block-like bearing part 15, which is connected to the machine frame.
  • the loading and loading station 1 is equipped according to the invention with a shaft 16 arranged in the longitudinal direction.
  • a drive gear 17 is arranged on the shaft 16, which meshes with a toothed rack 18 which is arranged in a fixed position with respect to the yoke-shaped arm 5. With the gear 17 also meshes a drive gear 19 which is arranged on a longitudinal shaft 20.
  • a first gear 21 of a gear transmission 21, 22 for the controlled drive of the guides 9 and 10 is arranged on the shaft 20.
  • the second gear 22 is freely rotatable at point 22a.
  • the gear wheels 21 and 22 are each operatively connected to a rack 23 and 24, the racks 23 and 24 are arranged on the arm 13 of the guides 9 and 10.
  • the rotational movement of the gear transmissions 21 and 22 in the opposite direction leads to a displacement upwards or downwards of the guides 9 and 10 in accordance with the direction of rotation of the transmission 17.
  • an adjustment process takes place
  • the support arm 13 of the guide 10 has a further rack 25 on its upper side.
  • This rack is operatively connected to a gear 26 which is mounted on the continuous shaft 27.
  • a gear 28 is also arranged, which also meshes with the rack 29, which is in operative connection with the stop 8 of the tubes.
  • the passage opening (H) for the pipes to be cut 2 is also set at the same time.
  • the passage (H) must be set such that the stop 7 a passage limitation is created that only allows the passage of a pipe.
  • the functional reliability of the various devices that are operatively connected to one another is extremely reliable, the adjustment movements of the various movably arranged components are carried out in full synchronism due to the mechanical operative connection of these components, using gear drives and toothed racks that can be driven by a centrally arranged actuating device .
  • the described movably arranged components can be replaced by technically equivalent devices without leaving the scope of the invention. It is essential for the invention that all components are operatively connected to one another and can be moved via a single, centrally arranged drive device. It is also important that the pipes to be separated are supported by rotatable balls, which prevents any friction between the pipe and the guide receptacle during the rotary movement and the feed movement of the pipe. This prevents the outer wall of the pipe from being damaged.
