Definitions

  • the invention relates to a device by means of folding cartons can be transferred to a transport device.
  • folding cartons present as flat blanks in a supply magazine are first removed from the magazine by such a device, then opened and finally transferred through the device to a transport device.
  • the transport device then transfers the opened folding boxes into a filling station, in which the folding boxes are filled and closed with one or more products.
  • Devices for transferring a carton to a transport device are, for example, from DE 10 2005 017 962 A1 or the DE 10 2007 023 964 A1 known. Such devices usually have one or more arms on which holding devices for the cartons are mounted.
  • the holding devices can be designed in particular as suction devices. By holding the flat carton blanks can be taken from a storage magazine and transported. Depending on the size and format of the carton blank, a suction device may have a single or multiple suction cups.
  • the arms of the device are driven continuously by a motor drive, so that a uniform rotational movement is performed.
  • the carton is replaced by other devices that around the Transfer device are placed around, unfolded.
  • the opening can be done in the simplest case by a stop element; For example, in the case of folding cartons that are harder to open, counter-suckers can be used for this purpose.
  • the opened carton can then be further processed by, for example, a spreading of the side, glue or insertion tabs.
  • the carton is transferred to a transport device. This is done in the simplest case by dropping the carton, causing it falls into a compartment of the transport device and is collected there. Subsequently, a new carton blank can be removed.
  • the removal of the carton blank, the opening of the carton and the transfer of the carton to the transport device takes place during a single revolution of each arm.
  • the WO 2005/019074 shows a generic type transfer device having a rotatably mounted first arm which is rotatably supported on a substructure via an axis. At this first arm, a second arm is movably supported by a bolt. The second arm is mounted on a guide element on a rail system having at least a straight portion.
  • the present invention seeks to provide an improved device for transferring a carton to a transport device, which can be realized economically favorable and allows a defined transfer of the carton to the transport device.
  • the device according to the invention is given by the features of the main claim 1. Useful developments of the invention are the subject of further claims appending to the main claim.
  • a cartoning machine according to the invention, which has a corresponding transfer device, is given by the features of the independent claim 9.
  • the inventive device for transferring a carton to a transport device has at least one arm which is displaceably mounted in a closed-loop rail system.
  • This rail system is not circular, but at least a portion of the rail system is formed as a straight line.
  • the at least one straight portion of the rail system may be the tangent of the bent portion adjoining this straight portion. This allows a smooth transition within the rail system so that a smooth circulation in the rail system mounted arm is made possible.
  • At least two sections of the rail system may be formed as a straight line, these two straight sections lying opposite each other.
  • the rail system typically needs to be made significantly larger than the prior art circular rail systems.
  • the footprint of the rail system at two opposing straight sections is about the same or even slightly less than the circular rail systems of the prior art.
  • on the side of the rail system opposite the transfer area there is a second area within which a processing of the folding box during a linear movement is possible. This simplifies the processing of the box, especially in such Folding boxes that need to be opened more complex or more complex.
  • the two opposite straight sections can in particular be parallel to each other.
  • the rail system is thus somewhat flatter than in the known circular rail systems, so that a particularly compact design is made possible.
  • a bent portion may be provided between each of two straight portions, the bent portion preferably being in the form of a circle segment of constant radius.
  • the straight section can in each case represent the tangent of the circle segment, so that a particularly smooth transition is possible.
  • the rail system may have a first straight section, followed by a first curved section.
  • This second curved section is adjoined by a second straight section, followed by a second curved section.
  • This second curved section then opens into the first straight section, whereby a closed rail system is formed.
  • the two bent portions may each have approximately the shape of a semicircle with a constant radius. In this way, the two straight sections can be formed as long as possible, with a compact design of the rail system is still possible.
  • remains for the processing of the carton and the removal of the carton from a storage magazine still the previous circular path obtained, so that no reorientation of the corresponding processing devices and the storage magazine must be done in a corresponding cartoning.
  • the transfer device has at least one rotatably mounted first arm.
  • a second arm is movably mounted, wherein the second arm can be slidably mounted in the rail system.
  • a plurality of first arms may be present, on each of which a second arm is movably mounted.
  • four or six first arms may be present in a device according to the invention.
  • the second arm is fastened to the first arm via a lever element. This lever element causes the second arm is pulled down behind the first arm, so that it is moved particularly quietly in the rail system.
  • the first arm can perform a particularly uniform rotation, since this first arm does not have to be mounted directly in the rail system.
  • a holding device for the folding boxes may preferably be arranged on the arm mounted in the rail system.
  • the holding device can be designed in particular as a suction device.
  • the holding device can have a single holding element-for example, suction element or gripping element-or several holding elements whose arrangement can be dependent on the dimension of the respective carton.
  • the holding device can be rotatably mounted on this arm in a preferred embodiment. This makes it possible to rotate the holding device to the outside, for example, the carton to be removed from the storage magazine. Subsequently, the holding device can be rotated inwards again in order to be able to pass through the individual processing stations along the transfer device.
  • the arm mounted in the rail system may have a separate drive which causes the movement of the arm within the rail system.
  • This drive may in particular be a linear drive.
  • the transfer device according to the invention can be used in particular in a cartoning machine for packaging a product into a folding box.
  • a cartoning machine has in addition to the transfer device according to the invention a storage magazine for the flat carton blanks and a transport device to which the unfolded carton is transferred from the transfer device at least a straight portion of the rail system of the transfer device is approximately parallel to the starting area the transport device.
  • This initial region of the transport device is that region into which the unfolded folding box is transferred.
  • transfer device 10 shown has a cross-shaped arm system 12 which is rotatable about a perpendicular to the plane extending central axis 14 and is rotated during operation by a motor drive not shown here in the counterclockwise direction.
  • the cross-shaped arm system 12 has in the present example a total of four first arms 20. At the outer end portion of each arm, a lever member 22 is rotatably mounted. The other end of the lever member 22 is also rotatably mounted on a second arm 24. On the second arm 24, a joint member 26 is pivotally mounted, so that a holding device, not shown in the drawing pivoted outwards and then "retracted" can be.
  • the individual arms 20 Upon rotation of the arm system 12 in the counterclockwise direction, the individual arms 20 perform a uniform or cyclic rotational movement on a circumferential circular path. By the arms 20, the individual lever elements 22 are also moved along with their moving on the arms 20 ends on a circular path. By the lever members 22 and the second arms 24 are moved.
  • the arms 24 are mounted with a guide element not shown in the drawing in a circumferential rail system 40.
  • This rail system 40 has no circumferential circular path, but rather the rail system 40 has two straight sections 42, 44 and two bent sections 46, 48.
  • the two straight sections 42, 44 run parallel to one another. They are interconnected by the two bent sections 46, 48.
  • the two bent portions 46, 48 each have approximately the shape of a semicircle with a constant radius.
  • the straight sections 42, 44 represent the tangents of the respectively subsequent curved section 46, 48, so that a smooth and smooth transition is given within the rail system 40, which leads to a continuous movement of the transfer device 10.
  • a member 50 is rotatably mounted on the hinge element 26, which carries the holding device for transporting the folding boxes.
  • the element 50 is coupled to the second arm 24 by means of a drive element such that upon rotation of the transfer device 10, the element 50 is always in the same rotational position with respect to the second arm 24, that is, the angle between the longitudinal axis of the Element 50 and the longitudinal axis of the second arm 24 remains the same.
  • the joint element 26 furthermore has an individual drive via a gear 60.
  • this individual drive the joint element 26 can be rotated together with the element 50, so that the flat carton blanks can be removed from the storage magazine.
  • this rotation can provide a constant speed during carton transport along sections 44, 46 and 42 to allow easy and reproducible processing and opening of the cartons in this area.
  • a transport device may be provided which has a plurality of spaced along driving finger, between each of which a compartment is formed, in each of which a carton can be used. These compartments can be filled by the transfer device from above, each with a carton, with the straight section 42 of the rail system 40, a controlled filling of the individual chambers is possible.
  • two obliquely extending straight sections may be provided, each connected by a bent section.
  • the bent portions could be made as circle segments having a constant radius as described above.
  • the corresponding transfer device could in this case also allow a compact design.
  • the rail system 40 could also have only a straight section.
  • the two ends of the straight section would be connected by a single bent section.
  • this bent portion should not have a constant radius in this case because the transition between the straight portion and the bent portion should be tangential. This would require a relatively large rail system so that the transfer devices known in the art would build somewhat smaller.
  • four straight sections could be provided, which can be interconnected by curved sections in the form of a quarter circle.
  • the rail system in this case would have the shape of a rectangle with rounded corners.
