Definitions

  • the present invention relates to a transition device adapted for moving an object from a first conveyor having a first speed to a second conveyor having a second speed.
  • the spacing between the incoming objects varies and the objects are positioned on the second conveyor at predefined positions.
  • the transition device is adapted to be used in a conveyor system.
  • 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 may be arranged on the conveying tracks either directly or via supporting means. Larger objects are often conveyed on supporting means also known as pallets, and smaller objects may be conveyed using a small carrier often referred to as a carrier puck.
  • Some products, such as boxes, packages or bottles are often conveyed directly by the conveyor tracks.
  • One common solution is to let a second conveyor run at a higher speed than the first, previous conveyor. With both conveyors running at constant speeds and with the objects of the first conveyor being positioned in a predefined manner, e.g. packed against each other, a predefined gap can be obtained between the objects on the second conveyor.
  • the objects are pulled from the first conveyor by the second conveyor. There will thus be a relative movement, i.e. slippage, between the product and the first and/or the second conveyor during the transition of the object.
  • the object will experience a sudden difference in speed at the moment it reaches the second conveyor, which can cause instability of the object.
  • the acceleration/motion of the objects is depending on the friction coefficient and is not completely predictable, which will give some deviations in the gap spacing.
  • the objects cannot be accurately positioned on the second conveyor which means that this solution cannot be used for feeding a cleated conveyor or for merging objects from different conveyors to one conveyor.
  • a system that can position objects can be provided.
  • the gap spacing between objects can be varied such as a positioning offset can be created.
  • the sensor can give object position feedback to the control system, which can use this information to control the conveyor speeds such that the products are positioned as desired on the second conveyor belt.
  • the objects are also pulled from the first conveyor by the second conveyor. There will thus be a relative movement, i.e. slippage, between the product and the first and/or the second conveyor during the transition of the object.
  • the object will experience a sudden difference in speed at the moment it reaches the second conveyor, which can cause instability of the object. Further, the acceleration/motion of the objects is depending on the friction coefficient and is not completely predictable, which will give some deviations in the gap spacing. The friction coefficient further sets an upper limit for the maximum acceleration that is possible. All products that are positioned on each of the conveyors are affected by the speed alterations, which will further affect the stability of the objects.
  • the first conveyor can be provided with an object holding means, e.g. a so called choke belt, such that the objects are held between the first conveyor and the choke belt or between two choke belts.
  • the objects are thus forced to accelerate with the first conveyor.
  • a photo-sensor will give object position feedback to the controls system.
  • the second conveyor usually travels with a constant speed. In this solution, all products that are placed on each of the conveyors are affected by the speed alterations. The gaps between the products in the choke belt section are determined by the momentary speed of the objects as the objects enter the choke belt section.
  • US 5,762,175 discloses a solution that ensures packs which arrive at irregular intervals from one another to be transported further at predetermined spacing from one another.
  • the incoming packs are accumulated in an accumulated group in the region of an accumulating conveyor, which transfers the individual packs one after the other, in accordance with the timing of the machine, onto an intermediate conveyor which in turn feeds the packs to the removal conveyor.
  • the separate packs are gripped in the region of the intermediate conveyor by means of two mutually opposite arranged belts and are thereby conveyed at high speed in a precise manner.
  • US 3,827,545 discloses a method and apparatus for changing the spacing between discrete flexible web products.
  • the discrete web products move on an inlet conveyor with a constant inlet pitch and a constant inlet speed and are transferred to an outlet conveyor moving at a second constant speed where the products are spaced apart with a second constant outlet pitch.
  • a speed regulator transfers the web from the inlet conveyor to the second conveyor with a fixed speed transfer function.
  • US 3,812,948 discloses a device that separates and conveys articles, such as chocolate bars, which are moved in engagement with each other by an input conveyor and are transferred by a periodically operating transfer member onto an output conveyor which operates in synchronism with said transfer member which engages the articles during their conveying movement and moves the same with a speed which is greater than the speed of the output conveyor.
  • the transfer member comprises a pusher which transfers the articles from the path of the input conveyor to the path of the output conveyor in such manner that the articles will be in spaced relation to each other on said output conveyor.
  • the output conveyor consists of an endless chain, which is fitted with actuators perpendicularly attached to the chain pushing the articles.
  • US 4,934,510 discloses a bottle inspecting assembly wherein a supply conveyor supplies a sequence of upright glass bottles at a first speed thereon to an intermediate conveyor comprising several sets of belts which grips the opposite sides of the bottles, accelerates them from the first speed to a much greater speed across a gap and deposits them on a delivery conveyor means which is driven at a second speed so that the bottles are in spaced, upright positions on the delivery conveyor to permit inspections to be made.
  • US 4,682,684 discloses a method and an arrangement for the transfer of objects from a first to a second conveyor, the latter being driven at a higher constant speed than the first conveyor.
  • a transfer of objects between conveyors equipped with driving or load contacting elements plate or a bar positioned at intervals of the total width of the conveyor
  • damage to the objects is avoided if these are given a temporary increase in speed at the moment of transfer.
  • the increase in speed occurs because the driving element of the first conveyor is tipped forward directly before the transfer in the direction of movement of the conveyor, so that the total speed of the object at the moment of transfer substantially corresponds to the speed of the second conveyor.
  • US 2003/014153 A1 discloses a production line for small parts or conductor ends that are transported by means of workpiece carriers from work station to work station in a production direction.
  • An interchange device is connected between the two transfer devices, the first transfer device handing over the work piece carriers to the interchange device and the interchange device feeding the workpiece carriers to the second transfer device.
  • the interchange device serves as an adapter for different workpiece carrier spacing (pitch dimensions) of the first and second groups.
  • US 4,987,991 discloses a system for changing the speed of conveyed sheets.
  • the system includes a speed changing belt operating at a constant linear speed, flexible holding means and an acceleration lobe on said belt.
  • the acceleration lobe is positioned to engage the trailing portion of the sheet and to provide a continuously increasing radius at the tangent contact portion as the belt travels around a pulley whereby the outer surface velocity of the lobe and the sheet in contact therewith continuously increase from the incoming speed to a desired second speed. All these systems may work fine for some types of objects, but are nevertheless depending on a given object spacing for the incoming objects of the feeding conveyor. There is thus still room for improvements.
  • An object of the invention is therefore to provide a transition device that is adapted to create a product flow with objects positioned at predefined positions from an infeed flow where the spacing between the objects varies.
  • the object is achieved in that the transition device is provided with an adaptive and variable acceleration.
  • a further object of the invention is to provide a dynamic positioning device comprising a transition device.
  • a further object of the invention is to provide a dynamic merging device that can merge two infeed product flows.
  • Another object of the invention is to provide a method that can create a product flow with objects at predefined positions from an infeed flow where the spacing between the objects varies.
  • the object of the invention is achieved in that the transition device is adapted to accelerate the objects individually from the first speed to the second speed with an acceleration rate that is dependent on the position of the object on the fist conveyor and the first and the second speed.
  • the transition device may comprise one or more transition rollers or transition belts that will transfer the object from the first conveyor to the second conveyor.
  • the transition roller or transition belt is controlled such that the object is individually accelerated. If one driven transition roller or transition belt is used, a corresponding support surface positioned opposite the transition roller or belt is used to support the object.
  • the support surface may be fixed with a low friction surface or may be a non- driven roll or belt.
  • the transition device is comprised in a dynamic positioning device that will position objects on a conveyor at predefined positions.

  • the dynamic positioning device 1 comprises a first conveyor 2, a second conveyor 3 and a transition device 4 positioned between the first conveyor and the second conveyor.
  • the speed of the first and second conveyor may be constant or may vary depending on the requirements on the dynamic positioning device and the number of objects that is to be handled during a specific time period.
  • the speed of the conveyors is however constant during the transfer of an object from the first to the second conveyor.
  • the first conveyor transports objects 7 with a first speed vi from a production line or the like.
  • the invention is especially suitable for high capacity production lines, with a product rate from more than 100 objects per minute up to 1000 products per minute or more.
  • the products may be e.g. cardboard boxes, poly-wrapped packs or bottles.
  • the products travelling on the first conveyor are supplied with a first flow rate, i.e. a specific number of products per minute, and with a varying spacing between them.
  • the dynamic positioning device will enable a flow of objects on the second conveyor where the objects are positioned at predefined positions and where the deviation of the spacing between the predefined positions of the objects is very small.
  • the absolute deviation will depend on e.g. the speed of the second conveyor, the size and weight of the object and the resolution of the measurement system and the sensor used, but is preferably in the order of less than 5%.
  • a predefined position for the object is defined as a region on the second conveyor in which the object can be placed without interfering with another object.
  • This region may have approximately the same length as the object but is preferably somewhat longer than the object in order to increase the tolerances of the system.
  • an object When an object is to be positioned on the second conveyor, it must be positioned within such a region. Depending on the product flow, this may lead to that some regions will be empty on the second conveyor. If the object is too late for a specific region, it will instead be placed in the next region, i.e. the next predefined position.
  • the size of a region and the spacing between the regions are preferably predefined depending e.g. on the type and size of the objects and the speed of the conveyors.
  • the transition device will receive objects travelling with a first speed from the first conveyor and will deliver the objects to the second conveyor travelling with a second speed that may be constant.
  • the first and second conveyors are arranged in a horizontal way, i.e. the carrying plane of the conveyors is horizontal such that the objects can lay or stand on the conveyors without falling off.
  • the transition device comprises one or several driven rollers or belts. Depending on the orientation of the transition device and the type of object, it may suffice with a single driven roller and a passive support roller or support surface, but two or more driven rollers may provide, depending on the objects, a better support for the transferred objects. In the shown examples, two driven transition rollers 5, 6 are used. These transition rollers are ramping up and down in speed for each object that travels on the first conveyor.

  • the object is only held by the transition rollers.
  • the rear part of the object may still be in contact with the first conveyor when the front part of the object is held by and accelerated by the transition rollers. In this case, the rear part of the object may slide some on the first conveyor.
  • the transition rollers will now accelerate the object to the same speed as the discharged product flow, i.e. to the speed v 2 of the second conveyor.
  • the object can now enter the second conveyor with the same speed as the second conveyor.
  • a first sensor 8 is used to detect when an object reaches the transition device from the first conveyor.
  • a second sensor 9 may be used to give object position feedback to the control system from the second conveyor. In this way, the objects are received to the transition device with a variation in time, and are delivered to the second conveyor at predefined positions.
  • the object is accelerated in a smooth, controlled way with no slippage between the rollers and the object and the acceleration of the objects is predictable and is not depending on the friction coefficient between the object and the conveyors.
  • the acceleration of an object is depending on the time when it arrives at the transition device and on the instantaneous position of the predefined position on the second conveyor, i.e. when the object must be fed to the second conveyor.
  • the acceleration rate and the time for the complete acceleration are also dependent on the speed of the first and the second conveyor.
  • the transition device can also be used to feed objects to the downstream second conveyor having fixed position devices 10, e.g. in the form of cleats, that define the positions for the objects.
  • the transition rollers are controlled so that products are securely fed into the pockets between the cleats in a continuous motion without stopping or restricting the upstream product flow. This is done by either shifting the acceleration step in time or to control the acceleration parameters such that the object will be placed at one of the fixed positions. In this way, the position of the object on the second conveyor can be controlled within the limits set by the object rate and the speeds of the first and second conveyor. If the object arrives at the transition device too late to reach a specific fixed position, the transition device will adapt the acceleration such that the object will be placed at the next position.
  • the dynamic positioning device is that the objects on the first conveyor can be transported at a constant speed, thereby eliminating upstream pulsations. Further, the objects are securely held during the acceleration phase, thus ensuring product stability.
  • the positioning on the second conveyor is done by a single driven roller or a pair of rollers in one step, which allows for a very compact machine design. The total accelerated inertia is minimized since only one object and the transition rollers must be accelerated, which reduces the requirements on the drive system. Further, the function is not depending on the length of the objects, which allows for a very flexible system that can handle different product variants.
  • the distance between the first and the second conveyor can be adapted to the length of the objects in order to avoid slippage.
  • the transition rollers can be positioned horizontally such that they grip the object from above and from beneath or vertically such that they grip the object from the sides. For some objects, it is possible to use only one horizontal roller that drives the object at the bottom of the object and where the top is guided by a guide rail. It is also possible to use one vertical roller that drives the object at one side and use a fixed guide rail as a support surface to support the other side of the object. For longer objects, short conveyors or belts may be used instead of transition rollers to accelerate the object and to give sufficient support to the object. It is also possible to use several transition rollers in order to support a longer object. Depending on the object, it is also possible to use other means to accelerate the object in a controlled way. A metallic object may e.g. be accelerated by a magnetic field.
