Definitions

  • the invention relates to a method and a device for transporting components in a tubular conveyor line between a component feed and a component receiving station.
  • This compressed air technology has several disadvantages. This goes hand in hand with very high air consumption, which, due to the fact that compressed air is a very complex form of energy, entails high costs. There is also a high mechanical outlay for sealing the conveying section and feeding in the compressed air with the aid of a so-called “blower body” as a switch in the conveying section. Pressure regulators, pressure accumulators and blowing valves also entail a great deal of pneumatic effort. Finally, the parts to be transported reach due to the compressed air supply a relatively high speed and therefore with a comparatively high kinetic energy in the receiving station. In this respect, the auxiliary technology is not at all suitable for certain components. Furthermore, the receiving station is relatively susceptible to wear due to the force of the impacting components. usually a supply hose - and the part to be transported, in particular with regard to the corresponding cross-sections, must be coordinated relatively precisely with one another.
  • Pneumatic conveyance of bulk goods is to be mentioned as a distant prior art, in which a mass flow of light goods is transported from a bunker via a tubular or hose-like conveying line with the aid of a blower.
  • the invention is based on the object of specifying a method and a device for the individual transport of components in a tubular conveying section, which allow a reliable and gentle conveying of parts with reduced design and energy expenditure.
  • the essence of the invention is to provide a volume flow of a gaseous working medium directed in the transport direction in the conveying path.
  • a gaseous working medium directed in the transport direction in the conveying path.
  • air is generally used as the working medium; if other gases are to be used for other reasons, for example for reasons of explosion protection, nitrogen, these can also be used as working medium.
  • volume flow is to be understood in distinction from a sudden air pulse, a more continuous gas flow that can be generated by a conventional fan. This volume flow is to be adjusted depending on the weight, cross-section, overall shape, etc. of the component to be transported so that the component over the The inclination and incline distances are to be taken into account with sufficient reliability.
  • the advantage of the method or the corresponding device according to the invention is the low energy requirement of the transport system since work is carried out without compressed air By simply adjusting the By providing the blower, which ensures the volume flow in the conveyor line, a defined transport speed and fine regulation of the airspeed of the components is possible, which ensures gentle component transport with correspondingly low loads, particularly of the component receiving station.
  • Preferred embodiments of the method according to the invention or the corresponding device are specified in subclaims 2 to 7 or 8 to 19.
  • the transport of the component to be conveyed is to be emphasized with the aid of a conveying projectile, which is reversely moved along the conveying path by reversing the volume flow from bubbles to suction.
  • This makes it possible to reliably transport problematic components with a relatively open cross-section, such as springs, with respect to their interaction with the volume flow.
  • No complex handling of the conveyor projectile is necessary, for example by removing it at the component receiving station and reinserting it at the beginning of the conveyor line. In this respect, there is also no need to stock a large number of projectiles, such a projectile is sufficient for each conveyor section.
  • the reversing conveyor projectile prefferably detects whether the conveying projectile has completely passed through the transport path and whether it has been successfully retrieved for the transport of the next component.
  • a soft reversal of the volume flow of the working medium is advantageous for the handling of the conveying projectile or the components themselves, which can be achieved by an appropriate design of the volume flow reversing valve on the blower feeding the conveying path.
  • 1, 2 and 3 are schematic representations of individual transport systems for components in three different embodiments
  • FIG. 4 shows a schematic sectional illustration of a conveying path between the end positions of the conveying projectile moving reversibly therein
  • Fig. 6 shows a section through a reversing valve
  • Fig. 7 is a perspective view of a multiple single transport system.
  • a transport device according to the invention is to be explained. So is between one as a whole with a component feed designated 1 and a component receiving station labeled 2 a tubular conveyor section in the form of, for example, an elastic hose 3 made of PTFE plastic.

  • the conveyor hose 3 can extend over several meters in length and height difference.
  • a blower 5 with its pressure outlet 6 is connected to the conveying hose 3 and generates a volume flow 7 of air in the conveying hose 3 as a working medium in the transport direction T.
  • a single loading unit 8 is provided in the component feed 1, which has a double chamber slide 9 with chambers open at the top and bottom as the central component.
  • the left-hand chamber shown in FIG. 1 serves as a component receptacle 10, into which screws 4 arriving in each case fall from above via a drop channel 11. The latter pass from a magazine 12 via a step conveyor 13 and a separating section 14 to the drop channel 11.

  • the component (screw 4) located in the component receptacle 10 thus falls into the delivery hose 3 and is entrained by the volume flow 7.
  • the flow rate of the air and the driving force thus acting on the screw 4 can be varied on the one hand by the power of the pressure blower 5.
  • the volume flow 7 can also be regulated by an outlet lock 17, which is arranged between the pressure blower 5 and the component feed 1.
  • This outlet lock 17 consists of opening slots 18 in the wall 19 of the delivery hose 3, the opening slots 18 being variably adjustable in the opening cross section by means of a slide ring 20. The larger the cross section of the opening slots 18 is set, the more air can escape therefrom and the lower the volume flow 7 acting on the component 4 to be transported.
  • a further outlet lock 17 ′ can be installed in the delivery hose 3 in front of the receiving station 2.
