Definitions

  • the invention relates to a device for labeling flat objects, such as compact cassettes, video cassettes or the like, with labels arranged in a supply stack for transfer to label holders, the label holders having suction bores which can be pressurized to accept the labels and having recesses in the objects and openings and edges of the labels corresponding to bevelled projections are provided, and with a device for making the labels sticky, the label holders being arranged to be radially movable on at least one step-wise rotating rotary head and from this to stationary function stations, namely a transfer station, in each of which a label is passed through a the label is taken over, an application station in which the label is made liable, and an application station for applying the labels to the objects.
  • Such a device is known from FR-A-1 517 527, in which the articles to be labeled are fed to the application station by means of an intermittently operating conveyor belt, where the conveyor belt then continues until the article in question has been labeled there in a stationary state is.
  • a disadvantage of this device is that because of the intermittent operation and the associated need to brake and accelerate large masses, namely the total mass of the conveyor belt itself and the objects located on it, again and again, such high operating speeds cannot be achieved as this is desirable, the intermittent operation also causing difficulties with the exact positioning of the objects to be labeled in the application station.
  • US-A-2 676 726 describes a device for applying flexible, perforated labels to articles or articles which have a hole or a depression corresponding to the opening of the label.
  • the labels are removed from the stack of labels by suction devices and placed on a shelf.
  • a label holder with a pen aligns the label with the pen.
  • the label is heated to make it adhesive and transferred through the label holder to the object to be labeled, the pin of the label holder entering the corresponding opening of the object and therefore being able to apply the label exactly to the object.
  • US-A-2 764408 describes a method and an apparatus for removing labels from a stack of labels, in which the labels are removed on label holders on a rotary head after removal from the label stack by compressed air flowing out of a nozzle, but the label holders only consist of non-positioning adhesive surfaces that hold the labels.
  • a particular disadvantage here is that the labels cannot be applied precisely positioned on the object to be labeled below, to which they are brought by means of the rotary head.
  • DE-U-1 884 257 describes a device for applying labels located on a carrier tape to an object by means of a rotary head which is provided with suction and pressing devices.
  • the labels are detached from the label tape in that the suction and pressing device moves radially from the rotary head to the labels and exerts a suction effect when they are touched, whereupon it is withdrawn while taking the label with it.
  • the rotary head then continues to rotate until the suction and pressing device provided with a label has reached the transport path of the objects to be labeled, where the suction and pressing device moves radially outward again onto the object to be labeled, pressing the corresponding label there, whereby the suction vacuum is switched off; and then withdrawn.
  • a disadvantage of this device is that the adhesive labels are used, which must be previously applied to a tape.
  • the device according to DE-U-1 884 257 does not allow precise positioning of the labels on the objects to be labeled.
  • the invention has for its object to provide a device of the type mentioned, which allows accurate and clean labeling by means of inexpensive labels to be removed from a stack at a higher speed than in the known device.
  • this object is achieved in that a conveyor chain running past the rotary head is provided with cams pushing the objects; and that the application station is provided with a lifting platform lifting the objects from the continuous transport chain above the height of the cams.
  • the labels are therefore used by at least one the radially movable label holder provided with the rotary head is gradually transported from the transfer station or the storage stack provided therein to the application station and is subjected to at least the following functions when the rotary head is at a standstill: taking over the labels by the label holder in the transfer station, making the labels adhesive in the application station, lifting the objects, in particular cassettes, from the continuously running transport chain for applying the labels by radially approaching the respective label holder to the object and by breaking off the vacuum.
  • a particularly preferred embodiment of the invention provides that the same, mirror-image, synchronously operating rotary heads with corresponding peripheral stations are arranged on the application station on both sides of the transport chain.
  • the overall labeling speed is practically doubled.
  • the application station has a horizontally lying application roller which can be provided with connector liquid and can be rotated about its vertically movable axis in order to apply a connector liquid to the labels.
  • the connecting liquid such as solvents such as perchlorethylene, which, when labeling compact cassettes made of plastic material, dissolve the compact cassette surface when the labels are applied, thereby ensuring a connection between cassette and label.
  • suitable adhesives of various types for example cold glues but also hot-melt adhesives, can also be applied to the labels in order to produce a firm connection between the object to be labeled and the label.
  • the labels can also be provided with adhesive adhesives, so that the labels can later be removed again, for example by the buyer of the labeled object.
  • the applicator roller is covered with fabric.
  • the application roll is spanned with a stocking or that the applicator roll is provided with a clamping device extending over its length, in which a rectangular piece of fabric is clamped on both sides, the latter embodiment having the advantage that the piece of fabric is so firm can be clamped so that it cannot slip. So that such a clamping device cannot impair the wetting of the labels, according to a further embodiment of the device according to the invention it is provided that the applicator roll can be rolled reversibly such that the clamping device is kept away from the label surface.
  • Another extremely preferred embodiment of the invention provides that the applicator roller rolls in a connector liquid bath located below it and vertically movable with its axis; and that the vertical distance :: of the axis of the application roller to the lower edge of the label located in a label holder is at least 30 mm.
  • the vertical distance :: of the axis of the application roller to the lower edge of the label located in a label holder is at least 30 mm.
  • the applicator roller is of slightly convex design.
  • the application of the connector liquid to the labels to be applied to the cassettes or the like can be further improved if the device according to the invention has a different design, which is characterized in that the application station, in which the labels are adhered, is opposite the label holder, in essentially vertically arranged, provided with a moistening wipe, in the end face facing the wetting cloth near the top of the plate opens a plurality of moistening channels, metered by means of a pump from a central reservoir with the labels adhered making connector fluid are acted upon; and that a collecting trough for receiving excess connector liquid is arranged below the humidification plate and is connected to the pump via a return line. It is particularly favorable if the moistening cloth is immersed in the connector liquid in the collecting trough, because this creates a wicking effect which ensures particularly uniform moistening of the entire moistening cloth and thus also of the label to be moistened.
  • a particularly favorable transfer of the labels from the supply stack to the label holder results in one embodiment of the device according to the invention, which is characterized by a guide trough arranged in the transfer station essentially horizontally and radially to the rotary head for receiving the supply stack of essentially vertically arranged labels, their cross section essentially corresponds to that of the labels and has at its front end facing the label holder or the rotary head at least two mutually opposite contact edges for holding the supply stack; a pressure plate which is arranged in the guide trough and can be moved longitudinally and presses the labels in the direction of the contact edges; and a braking device for relieving the pressure on the printing plate and thus the label supply stack after the label holder has been brought up during the label transfer from the supply stack to the label holder.
  • This embodiment of the device according to the invention enables a flawless, pressure-free transfer of the labels from the supply stack to the label holder.
  • the device according to the invention ensures rapid labeling of objects to be labeled, for example when labeling compact cassettes with fixation or precise positioning of both cassettes and labels, a throughput of one hundred and forty cassettes per minute and more can be achieved, while known labeling devices with fixation of the Labels only have a throughput of seventy cassettes per minute and labeling devices of the generic type achieve a penetration of about one hundred cassettes per minute without fixing; This progress is achieved, for example, by avoiding the time-consuming and complex removal of the labels from the carrier tape, to which the labels must also be applied beforehand.
