Definitions

  • the invention relates to a device for heating smaller workpieces, in particular for drying layers of paint on workpieces, which consists of a drying oven provided with infrared radiators and a rotating conveyor which transports the workpieces through the drying oven.
  • Drying ovens of various designs are used to dry and harden paint coatings on workpieces. Continuously operating devices are widespread, in which the workpiece by means of an endless chain conveyor or the like by means of heating elements, e.g. Infrared radiators, equipped tunnel oven is transported. This version is generally unsuitable and uneconomical for smaller workpieces. In addition, such a facility requires a lot of space.
  • the invention has for its object to design a device of the generic type in such a way that an economical heating of smaller workpieces is possible with a smaller space requirement.
  • the conveyor consists of a bogie with horizontally rotating support arms, which are rotatable in cycles in a drying station and each provided with a base plate for receiving workpieces and that the drying oven is hood-shaped and lifted at the drying station and is lowerable, the drying oven resting in its lowered position with its lower edge on the relevant base plate.
  • the workpieces are placed on a base plate and rotated into a drying station by means of the bogie, in which the hood-shaped drying oven is lowered onto the base plate.
  • the drying oven which is equipped with infrared radiators, heats the workpieces or the paint coating, whereby solvents evaporate and the paint hardens.
  • the drying oven is lifted off again and the bogie rotated by one cycle, so that a subsequent base plate loaded with workpieces reaches the drying station and the drying oven can be lowered.
  • the compact design takes up little space.
  • the hood-shaped design of the drying oven enables energy-saving heating or heating of the workpieces.
  • the bogie has the advantage that special stations can be set up for loading and unloading, for cooling or for further processing or assembly measures. If, for example, the bogie is provided with four support arms and a drive element which adjusts the support arms by 90 °, the station following the drying station can be used for cooling purposes, while the other two stations are used for loading and unloading. Furthermore, the base plates can be equipped with holding or carrying devices for the workpieces. Depending on the size of the workpieces, one or more workpieces to be heated can be placed on the base plate.
  • the drying oven is vertically displaceably mounted on a support post and is provided with a lifting mechanism which lifts the drying oven before the bogie rotates and lowered after the rotation phase.
  • the cyclic rotary drive of the bogie can be designed differently, for example, a pneumatic working cylinder can be provided as the drive member.
  • the lifting mechanism of the drying oven can also be equipped with a pneumatic working cylinder.
  • a particularly compact design results from the fact that the drying oven and the base plate have a circular floor plan. However, other floor plans are also suitable.
  • the entire device forms a structural unit, the support post of the drying oven and a support column supporting the bogie being connected to one another by a frame.
  • the device is expediently equipped with a programmable electronic and pneumatic control device which controls the heating temperature, the heating time and the drive elements for the bogie and the lifting mechanism for the drying oven.
  • the device shown in FIG. 1 is arranged on a frame 1 provided with feet 2. At one end there is a support post 3 which is provided with a lifting mechanism 4 for an oven 8.
  • the lifting mechanism 4 consists of a pneumatic working cylinder 5 with which a bearing head 7 running on guide rods 6 can be raised and lowered vertically is stored.
  • the drying oven 8 attached to the bearing head 7 is hood-shaped. It consists of a hood-shaped sheet metal housing, the inside with thermal insulation, for. B. rock wool is provided.
  • Infrared emitters 9 are attached to the inner jacket of the drying oven 8 in a position and number suitable for the heating purpose.
  • a support column 10 on which a bogie 11 is mounted.
  • the bogie 11 is provided with four horizontally rotating support arms 12 arranged offset by 90 °.
  • a drive member 13 rotates the bogie 11 in a controlled cycle by 90 ° in one direction of rotation.
  • a plate-shaped base plate 14 is fastened, which serves to receive the workpieces to be treated.
  • the base plate 14 is dimensioned and designed such that the lowered drying oven 8 lies with its lower edge 15 tightly on the base plate, and the oven space is closed. Each base plate 14 thus represents an oven closure when the drying oven 8 has been lowered onto it.
  • An electronic and pneumatic control device 16 which is attached to the support post 3, is programmed such that it controls the heating temperature of the drying oven 8, the heating duration, the drive member 13 for the bogie 11 and the hoist 4 for the drying oven 8, the heating temperature and the heating time is adjustable so that different treatment temperatures and times can be set.
  • the bogie 11 is provided with a bearing ring 17 on which four stop bolts 18 are arranged offset by 90 °.
  • the bearing ring 17 is rotatably mounted on a journal 19.
  • a hollow drive shaft 20 projects through the hollow journal 19 and has a pivotably mounted drive pawl 21 at its upper end is provided, which comes to rest against a stop pin 18 when the driver shaft 20 rotates clockwise and takes the bogie 11 with it. If the driver pawl 20 is rotated counterclockwise, the driver shaft 21 provided with a rear sloping surface slides over the stop pin 18 previously taken along.
  • the driver shaft 20 is rotated clockwise by 90 °.
  • its lower end is connected to the piston rod 24 of a pneumatic working cylinder 23 via a crank mechanism 22.
  • the bogie 11 If the piston rod 24 is extended, the bogie 11 is rotated by 90 °. If it is retracted, the driver pawl 21 slides over the bearing ring 17 of the stationary bogie 11 until it engages behind the subsequent stop bolts 18 and is ready for a further rotary movement of the bogie 11, which is triggered by the electronic and pneumatic control device 16. So that the bogie 11 in a working position cannot rotate, a locking pin 25 is provided, which can be displaced by a pneumatic actuating cylinder 26 into a bore 27 provided in the support arms 12. The working cylinder 23 and the actuating cylinder 26 are controlled by means of the electronic and pneumatic control device so that the bogie 11 can only be rotated when the locking bolt 25 is in the non-locking position.
  • the four base plates 14 of the bogie 11 are successively fed to the drying station in time, that is, moved under the drying oven 8.
  • the workpieces (not shown in the drawing) are placed directly on the base plate 14 (loading station) to be moved under the drying oven 8 in the next cycle.
  • the base plate 14 can, however, also be provided with plug-in holes for support rods or the like, which hold, for example, paint-sprayed workpieces in a position on the base plate 14 which is favorable for the drying process.
  • the Sta. Following the drying station tion can serve as a cooling station and unloading can take place on the station opposite the drying station.
  • the adjustable working cycle essentially depends on the heating duration set, which can be set from seconds to hours. The time required for lifting and lowering the drying oven 8, for disengaging and engaging the locking pin 25 and for rotating the bogie 11 by 90 ° is very short.
  • FIGS. 1 and 2 can be modified in many ways within the scope of the invention.
  • two support arms 12 can also be assigned to the bogie 11, the support arm 12 located on the outside serving to unload the cooled workpieces and to load them with new workpieces.
  • a cooling station and a common unloading and loading station can be set up.
  • Five and more support arms 12 may be desired if additional treatment or assembly stations are needed. In all these cases, the amount of twist must be adjusted, e.g. with two support arms 12 a rotation by 180 °, with three support arms 12 such a 120 ° etc.
  • Others e.g. electronic drive systems for lifting and lowering the drying oven 8 and for rotating the bogie 11 in cycles.
  • the drying oven 8 can have a different hood-shaped design, e.g. a square floor plan. Also, instead of infrared radiators 9 other heating elements, for. B. electrical resistance heating elements can be installed, and insulation made of porous refractory stones or the like can be useful.
