Definitions

  • the invention relates to a device for the simultaneous insertion of packaged goods, in particular stacks of blister packs, strip packs or the like move parallel and synchronously next to each other at least on a partial route of their circulation assigned to the insertion process, the packaged goods insertion chain being arranged on the side of the packaged goods transport chain facing away from the container transport chain and having carriages on which the packaged goods are inserted into the containers transversely to the chain running direction, with regard to their insertion movement, controllable push-in plungers are guided, furthermore with means for positioning the brochures in front of the push-in openings of the containers and with hold-down tongues acting on the packaged goods when inserted, which are arranged on hold-down plungers aligned parallel to the push-in plungers, which are longitudinally displaceable in parallel along the partial path and slides moved in synchronism with the carriage are guided, the slides in turn rotating and each with a cam roller on a self-contained cam track and the hold-down plungers for their longitudinal displacement with a control roller each on
  • Devices for simultaneously inserting packaged goods and brochures into boxes, the packaged goods transported in cells of the packaged goods transport chain being transferred together with the brochures into the boxes also transported in cells of the container transport chain cell by cell are known in various embodiments in packaging machines and are known, for example, in DE- A-33 41 573.
  • the hold-down tongues serve to depress the packaged goods from above before pushing them into the boxes and to keep them in shape and to guide them during the pushing process in such a way that the transfer process can eliminate any troublesome deformations of the packaged goods or cannot occur at all.
  • a hold-down tongue is connected to an insertion plunger.
  • Devices are known from practice which have all the features mentioned at the outset.
  • the slides guiding the hold-down plungers are connected to one another to form an independent, rotating and driven chain.
  • This chain is running overall above the partial path of the packaged goods transport chain assigned to the insertion process, the slides moving along the partial path in the chain running direction synchronously with the carriages of the packaged goods transport chain being guided in such a way that the hold-down tongues lower from above onto the packaged goods before it is pushed into the containers .
  • a disadvantage of such devices is that the packaged goods transport chain and the chain formed by the sled with their drives must be exactly synchronized with each other, since even small differences in running between the two chains can lead to mutual displacements between the carriage and the sled and thus lead to malfunctions in the insertion process.
  • the adaptation of the device to the changed packaged goods format which is required for a transition to packaged goods with a different height dimension between the chains, is very cumbersome and complex, because the chain formed by the carriage as a whole must be adjusted accordingly without the synchronization and the synchronization thereby the chains or chain drives may be impaired.
  • the invention is based, to simplify a device of the type mentioned in the construction and its operation, in particular with regard to the adaptation to different formats of the packaged goods, the task.
  • cam track and the control cam follow the rotation of the car over their entire length and are arranged on a cam carrier which consists of at least two parts, of which at least one cam carrier part provided with the sections of the cam track and the control cam assigned to the partial route and, for format adjustment relative to the carriages moving on the partial route, is adjustable in the direction perpendicular to the longitudinal direction of the hold-down plunger and to the direction of movement of the carriages, that at least one guide column is provided on each carriage is, which is aligned substantially perpendicular to the direction of movement of the carriage and to the longitudinal direction of the hold-down plunger and on each of which the slide is guided in a manner controlled by the cam track, and that the displacement thrust of the hold-down plunger in addition to the insertion distance of the packaged goods into the container by at least the width of the packaged goods transport chain is larger.
  • the carriages which are guided independently of one another on the guide columns, are moved along by the carriages during the rotation of the packaged goods insertion chain, so that the carriages and the carriages always run in exactly the right spatial association with one another and at the same speed with one another.
  • the sledges are therefore not connected to each other to form their own chain with their own drive.
  • To adjust the format when changing the height dimension of the packaged goods only the curve carrier part assigned to the partial route needs to be adjusted by the size of the change in format. Although this changes the total length of the slide's orbit, this is irrelevant because of the independence of the slide. It is only necessary to ensure that the guide length of the guide columns is at least equal to the adjustment stroke of the slide required for the format adjustment.
  • the hold-down tongues can be completely retracted from the packaged goods transport chain in the direction facing away from the container transport chain and therefore not with the packaged goods transport chain can collide.
  • control curve and the cam track between the mutually adjustable cam carrier parts are formed on connecting parts which overlap one another via at least the adjustment path and are displaceable in the direction of adjustment of the cam carrier parts.
  • the connecting parts prevent that gaps for the respective roles can arise in the course of their rotations between the cam carrier parts during their mutual adjustment.
  • a preferred embodiment of the connecting parts is characterized in that they have a U-shaped profile in cross section on one cam carrier part and engage in the connecting parts on the other cam carrier part, which are also provided with a substantially U-shaped receptacle, the control cam and the cam track being formed by surfaces are, which are formed on the inside of the profile legs of the two interlocking connecting parts in the axial direction of the control rollers or cam rollers side by side and aligned with each other. This enables the control and cam rollers to run smoothly and smoothly at the transition points between the two cam carrier parts.
  • a further preferred embodiment of the device is characterized in that the cam track in the adjustable cam carrier part has a lowering curve, by means of which the carriage is displaced parallel towards the carriage, the lowering curve being provided at a point on the partial path at which the hold-down plunger is located the hold-down tongue is located above the packaged goods still standing in front of the insertion opening of the container, and the control curve in the axial direction of the control roller has a width which is at least equal to the parallel displacement of the carriage by the lowering curve.
  • control cam and the cam track are designed so that the control roller and the cam roller are positively guided on their respective orbital path.
  • Such positive guidance can be achieved in a simple manner in that the control cam and the cam track are each formed by a guide groove in the side walls.
  • Another expedient embodiment is characterized in that the guide columns are provided in pairs on the carriage. The slides are then guided on each of the two guide columns and are thus secured against rotation about the axis of the guide columns in a simple manner.
  • the adjustable cam carrier part is displaceably guided in its adjustment direction and a height adjustment spindle is provided for the displacement, and that a measuring sensor is provided for detecting the setting of the adjustable cam carrier part, the measured values of which can be displayed on a display device.
  • the height adjustment spindle With the height adjustment spindle, the position of the adjustable cam carrier part can be precisely adjusted during format adjustment, whereby the detection of the set position and its display facilitate the adjustment and result in reproducibility and control of the setting.
  • a format adjustment to the dimensions of the packaged goods is also necessary in the direction of its insertion into the containers.
  • This format adaptation can be achieved in a simple manner in that at least part of the section of the control cam assigned to the insertion process is formed on a format part which is held interchangeably on the adjustable cam carrier part.
  • the format is then adjusted simply by changing the format parts that are suitable for the packaged goods.
  • the exchange is made easier by the fact that the format part is arranged on a swivel plate which can be swiveled about an axis parallel to the direction of movement of the carriage and is secured by a locking pin in the swivel position in which the part of the control cam located on the format part with the curve parts adjoining the cam carrier part flees.
  • the format part In the position of the swivel plate which is pivoted out of this position and away from the packaged goods and away from the trolleys, the format part is particularly easily accessible for replacement. Furthermore, the format part can be divided along the control curve and transversely to the longitudinal direction of the hold-down plunger and the part of the format part facing away from the packaged goods can be arranged on an overload slide which is guided on the swivel plate so as to be displaceable in the longitudinal direction of the hold-down plunger. Of the Overload slide with the part of the format part arranged on it is held in the working position advanced against the packaged goods by the force of a spring element, in particular a pneumatic or hydraulic cylinder.
  • a spring element in particular a pneumatic or hydraulic cylinder.
  • the overload slide prevents damage by avoiding the longitudinal displacement of the hold-down plunger in the opposite direction, which is generated by the control curve relative to the format part, and this compensates for the ram displacement relative to the packaged goods.
  • the force at which the overload slide slides out in the event of such a insertion fault can be set on the spring element, in particular on the pneumatic or hydraulic cylinder, which holds the overload slide in the working position.
  • the device can also be designed such that a switch is switched on in the control curve at the beginning of the partial route, through which the control curve can be connected to a deflection curve which bypasses the section of the control curve causing the insertion process and then opens into the control curve again. If packaged goods are missing, containers or brochures are missing, the insertion process can be prevented by activating the switch by turning the control rollers for the hold-down plungers on the relevant slides through the switch into the deflection curve so that the hold-down plungers are no longer moved.
