Definitions

  • the present invention relates to a transport device, a system and a method for transporting hose sections.
  • the correct speed of the double-belt conveyor is of particular importance.
  • the reason that the correct processing depends on the position of the tube pieces or the exact positioning in the transport system. For example, a valve slip or a label must be inserted or applied to the correct place on the hose running past.
  • the upper and lower belts must run synchronously with one another in order to counteract any friction between the belts and thus increased wear.
  • WO 00/26862 A1 discloses a transport device and a method according to the preamble of claims 1 and 12.
  • the object of the invention is therefore to propose a device or a system for transporting pieces of tubing that can be used flexibly and in a variety of ways and at the same time ensures the simplest and most precise operation possible.
  • a transport device for transporting hose sections which has at least one upper and one lower transport means for guiding the hose sections, upper and lower pressure exertion units for exerting contact pressure on the transport means, and at least one upper and one lower drive unit for driving the transport means.
  • the drive takes place at a substantially constant speed in a transport direction (z), with the transport means being arranged at least partially between the upper and lower pressure application units.
  • the drive units can be controlled electrically and are arranged within the device in such a way that speed differences between the transport means can be automatically compensated for.
  • a significant advantage of the invention is that a speed difference between the means of transport that inevitably arises during a longer process does not have to be adjusted using a lengthy and cumbersome manual process, but can be carried out automatically by selectively controlling electrically controllable drive units. In this way, in particular, the time required to compensate for possible differences in speed can be reduced. This leads to significantly shorter downtimes in production and thus to significant cost advantages.
  • the present transport device for transporting tube pieces is used in particular for transporting paper tubes.
  • the device in question can also be used to transport plastic hoses, fabric hoses, rubber hoses and the like.
  • the transport means are preferably arranged opposite one another and running at least partially parallel to one another. This enables a targeted and controlled alignment of the hoses or pieces of hose to be transported during transport.
  • the arrangement of three, four or even more than four means of transport is also conceivable.
  • a substantially constant speed is to be understood as meaning a movement that is uniform within certain time segments. However, this does not mean that the speed cannot be changed or varied. Rather, an adjustment of the speed is provided according to the invention.
  • speed differences develop between the means of transport in question, especially during longer operating times. These speed differences lead to an asynchronous course of the transport device, which in turn leads to the positioning problems mentioned in the subsequent processing steps. In this case, the speed differences can result, for example, from measurement inaccuracies, uneven wear or uneven loads.
  • the compensation according to the invention of speed differences between the two means of transport is to be understood in the present case as a compensation or an adjustment of the speeds of the two means of transport, so that the speed difference is at least reduced, preferably eliminated.
  • the compensation of the speed differences of the means of transport should be done objectively by means of an automated control of the electrically controllable drive units.
  • electrical control is to be understood more broadly within the scope of the invention, so that electrical control is understood to mean all control options in which the control includes an exchange of electrical signals.
  • the transport means for guiding the tube pieces are advantageously designed as belts, in particular as flat belts.
  • flat belts promise a particularly simple design and high belt speeds.
  • very large forces can be transmitted when using flat belts.
  • V-belts, V-ribbed belts, synchronous belts or toothed belts can also be used.
  • the upper transport means is at least partially arranged directly on the lower transport means. Arranged directly is to be understood in the sense of directly adjacent or contacting. Such an arrangement makes it possible, in particular, to exert a higher contact pressure on the workpieces to be transported, so that optimal positioning of the workpieces is ensured.
  • the means of transport have indices that can be detected by sensors for determining the speed differences.
  • the indices can be formed in particular as shaping indices, for example with protruding and/or recessed areas such as teeth, flags or the like on the transport means.
  • the indices that can be detected by sensors can also be formed as electromagnetic indices, for example by incorporating magnets, iron cores or the like.
  • imprintable indices that can be detected by sensors are also conceivable for determining the speed differences.
  • the pressure-exerting units can be formed as rollers, in particular as resilient rollers.
  • Such a design of the pressure application units promises, in particular, a particularly uniform pressure distribution, which is particularly advantageous with regard to preventing any incorrect positioning.
  • the pressure application units can comprise magnetic and/or magnetizable elements. These can be incorporated into the at least one upper and one lower means of transport, so that the means of transport attract each other. The pressure distribution can thus be evened out even better.
  • the rollers can also be movably mounted and opposite rollers can be attracted by means of magnetic forces, in which magnetic and/or magnetizable elements are applied the roles work. Further elements are conceivable which attract one another, for example on the basis of electrostatic or electromagnetic interaction, in order to exert the required pressure.
  • the drive units are preferably designed as electromotive drive units, in particular as electronic direct drives.
  • each drive unit is preferably assigned to a means of transport within the scope of effective controllability.
  • the speed difference can be compensated for in a particularly simple manner by changing the setpoint speed of a means of transport.
  • more than two drive units can also be provided in the device according to the invention.
  • the drive units can advantageously be in the form of motors which, in addition to controlling the angular position, also allow the acceleration and rotational speed to be controlled.
  • the drive units can be in the form of servomotors.
  • servomotors enable high positioning accuracy, high dynamics, high speed accuracy, a large speed range, a compact and lightweight design and a short run-up time.
  • the drive units can also be in the form of stepping motors.
  • the subject matter of the invention is also a system for transporting hose sections with the features of the independent system claim.
  • the present system includes the transport device described above for transporting hose sections, a detection unit for acquiring data to determine a speed difference between the transport means and a processing unit for determining a speed difference between the transport means on the basis of the acquired data. Finally, the present system also has a control unit for compensating for the determined speed difference.
  • the detection unit has at least one sensor for acquiring data, by means of which a speed difference between the means of transport can be determined.
  • the sensor can, for example, record the current currently being tapped at the means of transport, a current moment of the means of transport or other specific data from which a speed difference between the means of transport can be determined.
  • the sensors of the detection unit could determine the data required to determine the speed differences with the aid of indices arranged on the means of transport that can be detected by sensors.
  • the indices that can be detected by sensors can be shaping indices, such as protruding and/or recessed areas, electromagnetic indices, such as magnets, iron cores or the like, or also printable indices that can be detected by sensors.
  • the detection unit has at least two sensors which are preferably arranged at different positions in the system, in particular at different positions on the device for transporting hose sections.
  • the arranged sensors are designed and positioned in such a way that they enable an exact position detection.
  • the sensors can preferably be in the form of light barriers or cameras and can be arranged at the entrance and exit of the transport device, so that a speed difference between the transport means can be determined by simply comparing the distance covered with the target speed of the transport means.
  • the detection unit determines the difference in speed between the transport means on the basis of position data of the tube pieces to be transported.
  • a piece of tubing can be detected, for example, at two positions, so that the speed difference of the means of transport can also be determined here in a simple manner by comparing the distance covered with the target speed of the respective means of transport.
  • This can be sensory detectable indices can be arranged, for example, on or in labels that are attached to the tube pieces by means of the transport device in question before the tube pieces are transported. In this way, an arrangement of indices on the means of transport is not necessary, so that the transport device according to the invention or the system according to the invention can also be easily integrated into already existing transport devices or systems.
  • the detection unit determines the speed difference between the means of transport on the basis of data from different, in particular a large number of different sensors a processing unit is averaged and/or weighted and/or subjected to other statistical data evaluation methods.
  • the system has at least one supply unit for supplying individual tube pieces and/or at least one discharge unit for discharging tube pieces transported within the transport device.
  • the system can be provided within the framework of a particularly fail-safe system that additional control and/or alignment units for the control and/or alignment of the transported tube pieces are arranged on the feed and/or discharge unit.
  • the system according to the invention also has at least one, preferably a plurality of processing stations, in particular with regard to a process that is as automated as possible for the production of tubular packaging from individual tubular pieces.
  • the system in question can have, in particular, a bottom laying unit and/or a valve slip unit and/or a bottom unit and/or a carrying strap unit as processing stations.
  • the processing stations can advantageously be arranged uniformly along the transport device, so that the tube pieces can be fed to the individual processing stations one after the other with the aid of the transport means.
  • the individual system components can preferably communicate wirelessly on a server or cloud basis and/or via the Internet.
  • the system can also be designed as a learning unit and change parameters based on collected data and empirical values and thus adapt the operation.
  • the invention also relates to a paper bottom layer, comprising a transport device for transporting tube pieces, in particular comprising a system for transporting tube pieces.
  • the present method for transporting tube pieces includes in particular the steps of guiding the tube pieces by means of an upper and a lower means of transport, exerting a contact pressure on the means of transport by means of pressure exertion units arranged above and below the means of transport, driving the means of transport with a substantially constant Speed by means of at least two electrically controllable drive units, the transport means being controlled by the electrically controllable drive units in such a way that speed differences between the two transport means are automatically compensated for.
  • the method also includes the acquisition of data for determining a speed difference between the means of transport by means of a detection unit.
  • the acquisition of data for determining a speed difference can be carried out in particular using various sensors which are preferably arranged at different positions of the system in question in accordance with the explanations regarding the transport device according to the invention.
  • the present method can preferably provide that a speed difference between the means of transport is determined by a processing unit on the basis of the recorded data and/or the determined speed difference is then compensated for by a control unit.
  • compensation can take place in particular in that the control unit, depending on the speed difference determined by the processing unit, sends a signal to one of the drive units, which then adjusts the drive speed accordingly.
  • the method in addition to compensating for speed differences between the means of transport, particularly when determining the difference in speed between the means of transport on the basis of position data of the means of transport to be transported hose pieces, also includes a correction of the positioning of hose pieces.

  • the first processing station 4 for example, the end of the hose is pulled open so that the open bottom now lies in one plane.
  • a first valve sheet is introduced into the open bottom of the piece of tubing 6.
