Definitions

  • the present invention relates to a speed increasing device for a conveyor system comprising accumulation chains.
  • Conveying devices such as those which are used for moving objects between different stations in a factory, usually comprise a conveying track in the form of a belt or a chain.
  • the conveying tracks can be recessed in a trench with vertical side surfaces. Alternatively, they can be located on the horizontal upper surfaces of the trench or arranged in some other way.
  • the objects to be conveyed are arranged slidably in relation to the conveying tracks, either directly or via carrying means, which are also known as pallets.
  • a pallet is conveyed along the conveying device, which comprises different workstations.
  • the pallet can be stopped by a stop member such that an operation may be performed on the transported object.
  • the object may pass a specific workstation without an operation being performed on the object.
  • the stop member may for this reason be arranged to either stop the pallet or to let the pallet pass the workstation.
  • the conveying device is of a conventional type, in which all workstations are positioned after each other and the operations on the objects are performed synchronous, every pallet will stop at each workstation. If no operation is to be performed on an object at a specific workstation, the object will have to wait until the operation on the previous object at that work station is ready, until the object can continue. All pallets are in this case released at the same time and moves at the same time.
  • One advantage of such a system is that it is easy to predict the performance of the system.
  • One disadvantage of such a system is that it is not very flexible. If the operation time at a work station is long, all objects will have to wait that time, even if there is no operation performed on all objects. Thus, such systems are mostly used for a single product or when the differences in the products are small.
  • the operations on the objects are performed asynchronous, i.e. the pallet stops at a workstation where an operation is to be performed, and is released when the operation is ready.
  • a queue comprising a number of pallets may thus be required at at least a few of the workstations in order to compensate for the different through-flow times of the products and for the different operation times at a workstation.
  • a speed increasing device for an accumulation chain is well- known in the art, and is e.g. shown in US 2007034481 A, JP 2010235276 A, US 6244426 B, JP 6080228 A, JP 61267607 A, JP 4148709 A, US 5404997 A and US 5746304 A.
  • different solutions for mounting and operating the speed increasing device are used.
  • One problem in a conveyor system comprising two accumulation chains arranged at each side of the conveyor track, where each accumulation chain is arranged in a conveyor beam is to mount the speed increasing device in a simple and cost-effective manner in the conveyor beam. In most solutions, the accumulation chain is used in an open arrangement.
  • JP 6080228 A describes a speed increasing device mounted in a conveyor beam which consists of two conveyor beam profiles and which can be split in two parts.
  • An object of the invention is therefore to provide a speed increasing device that can easily be integrated in a conveyor beam of a conveyor system. Another object of the invention is to provide a conveyor system comprising at least one speed increasing device integrated in a conveyor beam.
  • Claim 1 1 contains an advantageous conveyor system.
  • the other claims contain advantageous embodiments and further developments of the speed increasing device.
  • a speed increasing device for a conveyor system where pallets are conveyed with an accumulation chain on a transport plane, comprising a body, a first actuating means and a second actuating means arranged on a first side of body, where the first actuating means and the second actuating means are adapted to simultaneously turn a first axle and a second axle from a first position to a second position, where the first axle and the second axle are arranged through the body
  • the object of the invention is achieved in that the first axle comprises a first eccentric end tap and that the second axle comprises a second eccentric end tap, when the first eccentric end tap and the second eccentric end tap extend from a second side of the body, and that the speed increasing device comprises a speed rail arranged on the first eccentric end tap and the second eccentric end tap, such that the speed rail is configured to be in either a first position when the first axle and the second axle are in the first position or in a second position when the first axle and the second axle are in the second position.
  • a speed increasing device that can temporarily raise the speed of a pallet in a conveyor system.
  • the speed increasing device can easily be mounted to a side wall of a conveyor beam without having to dismount the conveyor beam.
  • the speed increasing device is mounted with the first and the second axles extending through two holes in the conveyor beam and is fixed to the conveyor beam by two screws using T- nuts inserted in a groove of the conveyor beam. Since all that is needed to mount the speed increasing device is to drill two holes in the conveyor beam, a speed increasing device can easily be mounted to a conveyor beam without having to dismount the conveyor beam or the conveyor chain. The speed increasing device can further easily be removed from the conveyor beam without having to dismount the conveyor beam.
  • the speed increasing device comprises a speed rail which is configured to be in either a first position or a second position.
  • the speed rail is arranged in the centre of the conveyor beam, between the bearing surfaces for the feed rollers of the accumulation chain.
  • the speed rail In the first position, the speed rail is in a lower position, in which the upper bearing surface of the speed rail is below the transport rollers of the accumulation chain.
  • the upper bearing surface of the speed rail In the second position, the upper bearing surface of the speed rail is in a raised position, in which the upper bearing surface abuts the transport rollers of the accumulation chain.
  • the transport rollers of the accumulation chain will now roll on the speed rail, which will cause the speed of the pallet conveyed on the accumulation chain to increase its speed with a factor two, since the speed of the surfaces of the transport rollers will be higher than the speed of the accumulation chain.
  • the pallets are conveyed with the speed of the accumulation chain.
  • the feed rollers roll on the bearing surfaces of the conveyor beams, and the pallet bears on the transport rollers that do not rotate.
  • the transport rollers may rotate somewhat when a sudden load change occurs, and will rotate when a pallet is stopped with a stop member. But when the pallet is conveyed, the internal friction in the bearings of the transport rollers will allow the pallet to be conveyed forwards without slippage.
  • the speed rail is raised and lowered by an actuator.
  • the actuator turns an axle having an eccentric end tap on which the speed rail is arranged.
  • the axle is arranged in a bearing in a body of the speed increasing device.
  • the speed increasing device comprises at least two axles spaced apart which are operated by one or more actuators.
  • a linear actuator operates two arms connected to the axles, where the arms are connected to each other with a connecting rod.
  • each axle is provided with a separate drive unit comprising an electric motor. It is also possible to operate both axles with a single motor.
  • the speed increasing device is mounted to a side wall of the conveyor beam by the use of T-nuts arranged in a groove in the conveyor beam.
  • the axles are inserted through holes that are drilled or routed in the conveyor beam.
  • the holes may be predrilled at predefined positions or may be drilled when needed.
  • the speed rail is placed on the axles.
  • the eccentric end taps are provided with bushings and the speed rail rests on the eccentric end taps with cut-outs in the speed rail.
  • the speed increasing device comprises more than two actuating means, i.e. more than two axles acting on the speed rail.
  • the speed rail can be made longer if the pallet is to be conveyed with a higher speed over a longer distance. It is also possible to position several speed increasing devices next to each other in order to increase the length of the total speed increasing device.
  • the speed increasing device is intended for heavy duty conveyors comprising accumulation chains as conveying means.
  • an accumulation chain is arranged on each side of the conveyor.
  • the accumulation chains are moved forwards on the conveyor beams, and the pallet bears on the transport rollers of the accumulation chain and is in this manner conveyed forwards by the rotating feed rollers.
  • This type of conveyor is thus adapted for heavy loads of up to 100 kg and more.

  • the first axle 7 is arranged in the body through a first bearing 9 and is provided with a first eccentric end tap 1 1 .
  • the second axle 8 is arranged in the body through a second bearing 10 and is provided with a second eccentric end tap 12.
  • the first axle 7 is adapted to be turned by the first actuating means 5, and will rotate around a first rotational axis 3.
  • the second axle 8 is adapted to be turned by the second actuating means 6, and will rotate around a second rotational axis 4.

  • the speed rail 17 which is resting on the first eccentric end tap 1 1 and the second eccentric end tap 12 is also moved upwards. This will cause the upper bearing surface 19 of the speed rail 17 to come in contact with the transport rollers 46 of an accumulation chain 45 when the speed increasing device is mounted in a conveyor beam.
  • the speed rail is preferably made from a metal, such as steel or aluminium. The transport rollers will start to roll on the upper bearing surface of the speed rail, which in turn will increase the speed of the pallet conveyed by the accumulation chain.
