Definitions

  • the invention relates to a packaging machine for packing containers, in particular bottles, in containers, in particular boxes, trays or boxes, according to the preamble of claim 1.
  • a packaging machine for packing and unpacking small packs in or from open transport containers is known from DE-B-33 16 479 and EP 0 124 854 A3.
  • Containers such as bottles, are brought via a conveyor belt into the reach of a support designed as an extension arm, to which gripper heads are attached to a gripper carrier.
  • the containers transported here are generally marked with labels.
  • the containers are arranged on the conveyor belt so that they can be gripped by the gripper heads of the gripper carrier.
  • the direction in which the labels of the containers point is completely arbitrary.
  • the containers are made by the Gripper heads removed from the conveyor belt; then the support designed as a boom is brought into a delivery position in which the gripper heads can lower the containers into open transport containers.
  • the containers thus have the same, unordered, statistically distributed position of their labels in the transport containers as they are arranged on the transport belt.
  • transport containers should often be used for containers that give no indication of their contents. Then, however, the labels of the containers must be arranged so that they can be seen through inspection holes in the sides of the container. In addition, buyers are more inclined to purchase containers lined up in an orderly manner. With the known packing and unpacking machine described above, it is not possible to carry out the necessary alignment of the containers visible to the outside through the openings in the side walls of the transport containers during the packing process.
  • a packing machine which, in continuous operation, removes containers, here bottles, from a conveyor belt and packs them in transport containers.
  • the bottles in the transport containers are again in statistically distributed positions in their compartments in the transport containers, so that the labels on the bottles point statistically distributed in different directions and can only be recognized from the outside by accident.
  • the device proposed in DE-OS 37 28 291 requires an additional work step, since the bottles are packed by a separate machine and then have to be transported via a conveyor belt to the alignment device for their intended use. This requires additional equipment and time.
  • this document states that one or more adjusting devices for rotating the bottles in the crate are to be operated via a common motor, the alignment process being terminated using separate coupling elements.
  • the signal which indicates the alignment of the bottle according to its label is intended to trigger the coupling assigned to each individual setting device, as a result of which the alignment process of the bottle in question is ended.
  • the invention is based on the object of avoiding the disadvantages of the cited prior art and in particular a packaging machine of the type mentioned at the outset with discontinuous or continuous mode of operation for packing containers, in particular bottles, into transport containers which are open at the top, in particular boxes, trays or cartons,
  • a packaging machine of the type mentioned at the outset with discontinuous or continuous mode of operation for packing containers, in particular bottles, into transport containers which are open at the top, in particular boxes, trays or cartons To propose that aligns the containers during the packing process, which will be recognizable after being deposited through inspection holes in the side walls of the transport containers, so that their labels are visually uniformly perceptible through the inspection holes in the transport containers in a uniformly aligned manner, the packaging machine being relative should be uncomplicated and robust.
  • the packaging machine has means for aligning the containers at least on one of the gripper heads, which grasp containers which can be recognized through the holes in the containers after being deposited in the containers.
  • a packaging machine designed in this way is able to pack containers as well as to align the later containers in the containers according to the identification means or label during the packaging process.
  • the packaging machine also has on the at least one gripper head a sensor for a gripper head provided with an alignment device, which enables the surface of each container to be aligned to be scanned, sensor identification means to be sensed thereon, and to be oriented during the alignment process.
  • Alignment is carried out by a drive for rotary alignment, the gripper carriers or the gripper heads being interchangeably mounted, and the at least one gripper head is controlled by electronics which evaluate the signals from the sensors for the purpose of controlling the rotary alignment of the containers, the Electronics is integrated in the gripper carrier or the gripper head.
  • the alignment device As already mentioned at the beginning, a main area of application of the alignment device according to the invention is in filling or Packaging of labeled bottles. However, it is pointed out that the alignment device can be used with great advantage wherever the general focus is on the alignment of objects provided with identification means.
  • the gripper heads in a discontinuously or continuously working packaging machine for the containers which are visible after being placed in the transport containers through holes in the transport container sides, are provided with means for aligning the containers and sensors are also arranged on the gripper carriers or gripper heads a very compact, functional design.
  • the gripper carriers are mounted with the gripper heads in such a way that they can easily be exchanged for those that match the respective container sizes. In this way, the packaging machine can be easily adjusted to any container to be packed or to any transport container to be packed in a short time.
  • each gripper head is provided with its own electric or electropneumatic individual drive. It is also possible to additionally equip each gripper head with a button that determines whether a container has been gripped at all.
  • Each electrical or electropneumatic individual drive of each gripper head can be controlled separately by means of a key pulse which is emitted by the key.
  • the gripper heads are particularly easy to control via programmable electronics, which evaluate the signals from the sensors or the push button and convert them into control pulses for the individual drives.
  • Electronics is particularly suitable here for a programmable logic controller (PLC) that is already provided with power levels. These power levels make it possible to supply the individual drives with electrical current directly via electrical feed lines. This eliminates the need for any electromechanical relays. In this way, lead wires can be saved in various applications, which makes the gripper carriers even easier to replace with the gripper heads, which is extremely important in practice.
  • PLC programmable logic controller
  • the gripper carrier can be designed so that it can be replaced with quick connectors for the power supply of the electronics. and the individual drives of the gripper heads are provided, so that each gripper carrier can be exchanged in the shortest possible time, including gripper heads, individual drives, sensors and the electronics.
  • the sensitive parts of the sensors In order to protect the sensitive parts of the sensors from mechanical influences, it can be advantageous to use these parts, e.g. have a light source and a light receiver to install in the gripper carrier itself, or in the electronics or the PLC.
  • the scanning and / or response signals then have to be emitted onto the containers via glass fibers or their reflections have to be conducted from the containers to the sensitive parts of the sensors.
  • the reflected light beam which contains information about the position of the container label, is preferably directed onto a fast-reacting photosensitive element.
  • a fast-reacting photosensitive element In the case of a continuously operating packaging machine, it makes sense to supply the individual gripper carriers, or their electrical components, with power via grinders which run over current collector rails.
  • control signals for a full revolution are first applied to each alignment device. This advantageously ensures that uniform conditions for aligning the containers are created in the course of this first rotation of the container. Otherwise, it could happen that the identification means of a container is sensed from the start in any arbitrary position. The alignment of the container in question would be very imprecise in this case, since the sensor would immediately give the command to stop the driving device of the alignment device, as a result of which the identification means would be inadequately aligned.
  • the beginning of the identification means is sensed during the first or at least in the course of the second rotation. As the rotation continues, the end of the identification means is also detected.
  • existing electronics for controlling the alignment process precisely know and store the speed at which the containers to be aligned are rotated, they are able to use these values to calculate when the rotation of the container is to be stopped, in order to precisely determine the bottle to align with the center of the label.
  • the control electronics calculate the spatial variables from the existing relationship between the interval between the detection of the start and end of the label, the remaining rotation time and the speed of rotation. In order to take into account the inertia of the rotating container and the friction losses, the electronics provide a control impulse to stop deliver the container to be aligned with a certain reserve. The additional rotational movement of the container due to the inertia of the container will in this way move the container into its final, aligned position.
  • the rotation of the container can be accomplished particularly easily if a rotating part is provided for each container, via which the container can be rotated.
  • Such an arrangement can be designed both for a standing and hanging holder of the container.
  • the rotating part can be designed as a turntable on which the container can be placed, or the rotating part can have a holding device for hanging the container, for example a so-called gripper tulip.
  • Bottles 12 are transported via a conveyor belt 20 in the direction of arrow 12a into the effective area of gripper heads 24 of a gripper carrier 26.
  • the gripper carriers 26 are held vertically displaceably on a guide 19.
  • a support structure designed as a cantilever arm 8 leans back into a specific position.
  • the movements of the cantilever arm 8 are controlled via a gear, a crank and a coupling rod 28, the latter being attacked by the electric motor.
  • the upward and downward movements of the gripper carrier 26 or the gripper heads 24 are driven by an electric motor which is mounted on a boom platform 18. If the boom 8 is in its reserve position and the required number of bottles have been conveyed by the conveyor belt 20 into a position in which the gripper heads 24 can grip the bottles by their necks in the lowered state, the gripper carrier 26 is lowered so that each gripper head 24 can grab his respective bottles. When this gripping process has ended, the gripper carrier 26 is raised and the boom 8 is brought into the pivoted-out position. The gripper carrier 26 is then lowered, as a result of which the bottles 12 are introduced into a box 14, which is located under the gripper carrier 26 in the required position. Necessary fine adjustments of the box 14 can be made during the packing process still be carried out via a container centering device 38, which automatically fine-tunes the boxes when the gripper carrier 26 is lowered.
  • retaining means 15 are provided which hold the boxes in the desired positions.
  • each gripped bottle 12 can be rotated. Before the start and after the start of the rotational movement, the surfaces of the bottles 12 are scanned contactlessly by sensors 30.
  • the sensors 30 are provided with a radiation source, which mostly emits light onto the surface of a labeled bottle 12. This light serves as a scanning signal and is reflected from the surface of the bottle 12 in a characteristic manner. As soon as the light beam hits the bottle label, the characteristics of the reflected light beam change. The sensor detects this change e.g. with a photosensitive cell that emits an electrical control signal.
  • the individual drives of the corresponding grippers can be used heads 24 are controlled so that they always make a rotation of the bottle through 180 ° or another appropriate angle before the measurement results of the sensor 30 of the respective individual drive of a gripper head 24 are used for control.
  • the bottles 12 which are held by the gripper heads 24, have reached a position in which the bottles are inserted into the boxes 14 in the required orientation, they are released.
  • the gripper carrier is then withdrawn at least so far that the boxes 14 can no longer collide with parts which are mounted on the gripper carrier. Then the filled box 14 is released by the one restraining means 15 and conveyed in the direction of the arrow 14b.
  • control namely electronics, in particular a PLC or a single board computer
  • the control cabinet 58 receives the signals from the various sensors of the gripper heads, which are evaluated and converted into control pulses for the individual drives of the gripper heads 24.
  • the electronics contain additional time circuits which switch off the individual drives for aligning the bottles 12 even after a short time when the sensors 30 have not emitted a signal. This recognizes that there is likely to be an accident. This avoids the fact that the individual drives are controlled without performing their intended function. E.g. overheating of the individual drives can be prevented.
  • Self-sufficient control can also be used.
  • the gripper carrier 26 can be replaced together with its gripper heads 24, its individual drives and its sensors.
  • FIG. 2 shows the cycle packing machine 10 in an embodiment in which the empty boxes 14 are moved transversely to the direction of delivery movement of the boom.
  • the bottles 12 are also moved transversely to the direction of movement of the boom 8 of the cycle packing machine.
  • the equipment and function of the cycle packing machine are essentially the same as the cycle packing machine 10 shown in FIG. 1.
  • FIG 3 shows a cycle packing machine with a total of four gripper carriers 26.
  • the empty boxes come in the direction of arrow 14a and are held in the desired positions required for packing the bottles 12 until the packing process is completed.
  • the filled boxes 14 are then conveyed in the direction of arrow 14b out of the effective range of the cycle packing machine 10.
  • the bottles 12 to be packed are moved along the lines 12a into the effective range of the gripper carriers 26 or the gripper heads 24 mounted thereon.
  • the control of the alignment process of the bottles according to the label is carried out via control electronics, which are alternatively stationary in the switch box 58 or on the gripper head or in the single board.
  • FIG. 4 shows a continuously operating packaging machine, which is referred to below as a continuous packaging machine 100.
  • Their basic structure emerges from DE-PS 34 31 066.
  • Electronics are indicated by reference numerals 160a and 160b.
  • the electronics or PLC 160a is intended to show that it is possible to provide an autonomous control for all rotating gripper carriers 126 or gripper heads 124 which rotates with the rotating gripper carriers or gripper heads.
  • Reference number 160b is intended to indicate electronics for autonomous control, which is mounted separately on each rotating gripper carrier and controls its alignment function. In the latter case, it is possible for the electronics or PLC 160b together with the associated gripper carrier 126 or the associated gripper heads 124 and the associated sensors 130, including the centering means 138 as a whole, to be light and exchange quickly. These units are guided and controlled with or without separate electronics or PLC 160b on rods 119 or rollers on rotating cam tracks 118.
  • each (possibly “to be controlled”) required gripper 124 is assigned a separate individual drive and a separate sensor 130, so that the bottles in question can be rotated into a position in which their label is arranged in an orderly manner from the outside, through the viewing holes 117 in the boxes 114 are clearly visible from the outside.
  • the boxes 114 which are to be filled with bottles 112, are conveyed past the continuous packaging machine 100 via a conveyor device 122 in the direction of the arrow 114a for loading with bottles 112.

  • the gripper carriers 126 are guided on rods 119 and rollers (not visible here) along the schematically indicated cam tracks 118. Rotating link chains (not shown here) are generally used to move the gripper carriers 126. Alignment of the bottles according to the viewing holes in the crates takes place after the bottles have been lifted off the conveyor belt 120 and before the bottles fit into one on the conveyor belt 122 moving boxes have been discontinued, i.e. while the gripper carriers change their direction of movement by 180 °.
