Definitions

  • the present invention relates to a label transporting device for a price calculating scale.
  • Price calculating scales for which the device according to the invention is intended ascertain the weight of the respective goods and enter the weight into a calculating mechanism in which a multiplication is effected with the set price per weight unit.
  • the label is printed upon with the indications required for the price marking and then the label is issued.
  • an object of the present invention to provide a label transporting device for applying the labels issued by a calculating scale onto the wrapped goods after the goods have been weighed, which device will be able directly to convey the labels issued by the printing mechanism onto the wrapped goods while the goods pass by the calculating mechanism of the scale.
  • FIG. 1 diagrammatically illustrates a device according to the invention for applying labels to goods wrapped in a bag of synthetic material.
  • FIG. 2 shows a circuit for use in connection with a microswitch actuated by a suction pipe.
  • FIG. 3 represents a modification of that end of the suction pipe which is located at the side of the suction opening.
  • the label transporting device is characterized primarily in that it comprises a suction pipe which is linked to the calculating mechanism and is adapted to be tilted back and forth, the suction pipe being connected to a vacuum pump and having its movement controlled in such a way that in its starting position it is adapted by means of its suction opening to engage from below the label ejected by the printing mechanism, to grasp the same and after pivoting ice to press it onto the wrapped goods while at the same time a venting of the suction pipe is elfected; thereupon the suction pipe is pivoted back to its rest position.
  • the pivotable suction pipe is preceded by a cylinder piston system passed through by suction air in a transverse direction in which the piston during the closing of the suction opening of the suction pipe by the label, is displaced in the cylinder whereby through the intervention of intermediate members the pivoting movement of the suction pipe is effected against the thrust of a spring.
  • the present invention results in a design in which the pivoting of the suction pipe transporting the label is effected directly by suction air which is adapted to effect both the adherence of the label to the suction pipe and also the pivoting movement of the latter.
  • the rest position of the suction pipe after a pivoting movement is so selected that the suction opening of the suction pipe is located at a slight distance from and below the depositing plane for the label when the latter leaves the printing mechanism.
  • a rotatable cam catches from below the suction pipe and by means of a pulse emitted by the printing mechanism after the ejection of the label lifts the suction pipe with its suction opening by turning the same directly onto the label which latter thereby closes the suction opening. In this way it is assured that the suction air generated by the vacuum pump can pass through the suction pipe in an uninterrupted flow also when the label is already above the suction opening.
  • the sucking of the label onto the suction pipe is efiected only when the suction opening, in view of the slight tilting movement of the suction pipe, is brought into direct engagement with the label and when the label closes the suction opening. Only in view of this closing action the suction air will bring about the movement of the piston which in its turn during its movement and through the intervention of intermediate members permits the pivoting movement of the suction pipe which latter applies the label to the goods which goods at this time are in the pivoting path of the suction pipe and to which the ejected label belongs.
  • the suction pipe may consist of two pipe sections which for purposes of venting the suction pipe are connected to each other so as to be tiltable or pivotable relative to each other against the thrust of a spring.
  • This design of the suction pipe has the advantage that the goods to be provided with the labels may have different heights.
  • the suction pipe with the label reaches the goods at a different height, the suction pipe will tilt whereby the suction effect is lost due to the fact that the suction pipe is vented at the tilting point.
  • the pressing of the label onto the goods and the venting of the suction pipe coincide.
  • the label sticks to the goods and in view of the absence of a suction efiect, the suction pipe with its free suction opening will pivot or tilt back to its rest position and will be ready for the application of the next label to the next goods.
  • a microswitch may be so arranged in relation to the suction pipe that it will respond to the suction pipe reaching its starting rest position and will cause the printing mechanism to issue the next label.
  • the arrangement shown therein comprises a price calculating scale the front portion of which is indicated by the lines 11.
  • the device for applying the labels issued by the printing mechanism to the goods is arranged on one side of the price calculating mechanism with printing mechanism.
  • the drawing shows only the depositing plate 2 which is provided with a wide longitudinal slot.
  • the depositing plate 2 has its free end provided with the angled-off portion 3 in order to prevent the label 4 from sliding therebeyond when the label passes from the non-illustrated printing mechanism to the depositing plate 2.
  • the depositing of the label 4 is eflfected at the rhythm or rate of the weighing operation of the scale and, more specifically, in such a way that the respective label 4 pertaining to the weighed goods is deposited when these goods are moved into the range of the device according to the invention.
  • the transport of the goods may be effected on driven conveying rollers 5 as illustrated in FIG. 1 or may be effected by means of a corresponding conveyor belt.
  • the goods 6 represent a bag of synthetic material containing, for instance, fruit or the like, previously weighed by the scale.
  • the main components of the device according to the present invention are represented by a suction pipe comprising two pipe sections 7 and 8 which are linked to each other at 9 and consequently can tilt or pivot relative to each other.
  • the two pipe sections 7 and 8 normally in alignment with each other and are held in this position by means of a nonillustrated spring. In this aligned or stretched position, the gap between the pipe sections is sufficiently narrow so that essentially only suction air can pass into the suction pipe through the suction opening 10 at the free end of the pipe section 7.
  • the suction air is generated by a vacuum pump connected to the suction line 11.
  • the suction pipe is pivotally journalled by means of the hollow shaft 12 the inner space of which, on one hand, communicates with the suction pipe section 8 and, on the other hand, communicates with the suction line 13 which leads into one end of the cylinder 14.
  • Cylinder 14 communicates with the conduit 1!]. so that the suction air passes in transverse direction through the cylinder 14.
  • a longitudinally displaceable piston 15 the piston rod 16 of which is eccentrically linked to a gear 17 which later meshes with a gear 18.
  • Gear 18 in its turn is fixedly connected to the hollow pivot shaft 12.
  • the outer circumference of gear 18 is additionally engaged by a pull chain 19 with a spring 20 so that the pivoting of the suction pipe 7, 8 is efiected in counterclockwise direction against the pulling force of spring 20.
  • the suction pipe 7, 8 is in FIG. 1 shown in a position in which the label closes the suction opening 10, in other words, in a position in which by means of the suction air the pivoting movement of the suction pipe 7, 8 is brought about.
  • the starting rest position of suction pipe 7, 8 is at a somewhat lower level so that a certain distance will prevail between the engaging plane of label 4 on plate 2, on one hand, and the suction opening 10, on the other hand, so that the suction air below the label 4 can enter the suction pipe 7, 8 without afiecting the location of the label 4.
  • the pivoting movement of the suction pipe 7, 8 is initiated when the rotatable cam 21 receives a turning pulse from the printing mechanism as a result of which the rotatable cam 21 is pivoted into the illustrated position in which it pivots the suction pipe 7, 8 from its starting rest position into the illustrated starting position.
  • a label is located on plate 2 as shown in FIG. 1, the label 4 closes the suction opening 10. Since therefore suction air can no longer be drawn through the suction opening 10, an underpressure is created in the suction pipe 7, 8, in the hollow shaft 12, in the conduit 13, in cylinder 14 and in the adjacent conduit up to the vacuum pump. As a result of this underpressure, the piston 15 moves toward the left with regard to FIG. 1.
  • the pull magnet 27 is through terminals 25, 26 for the operating voltage of magnet 27 arranged in series with the rest contact of the microswitch 23.
  • the pull magnet 27 which is adapted to initiate the operation of the printing mechanism will attract only when the rest contact of the microswitch 23 is closed. This will be the case when the suction pipe 7, 8 is located in its rest position in which a further label 4 may be attracted.
  • the microswitch 23 thus will assure that the printing mechanism will release the next label only when the suction pipe 7, 8 has again returned to its rest position.
  • a label transporting device for use in connection with a calculating scale comprising a mechanism for printing and issuing labels grasped by suction and pressed by way of pivoting an adhesive containing side thereon upon weighed packaged goods with the price of the weighted goods with simultaneous discontinuance of suction flow and thereafter pivotally returning automatically to label receiving position, which includes: pivotable suction pipe means having a suction mouth and being pivotally journalled so as to be movable controllably in one direction from a label receiving position to a label applying position to apply the label to weighed goods, said suction pipe means also being movable controllably in the reverse direction, vacuum pump means operable to communicate with said suction pipe means to create a suction eifect therein to cause said suction pipe means to pick up and hold a label, and means capable of having suction air passage transversely therethrough associated with said suction pipe means always subjected to suction air that efiects pivotal movement of said suction pipe means only when opening thereof becomes closed through a label located thereon and oper
  • a device which includes cylinder-piston means interposed between and communicating with said suction pipe means and said vacuum pump means and operatively connected to said suction pipe means, said cylinder-piston means being operable in response to a suction eifect created therein when said suction mouth of said suction pipe means is covered and substantially closed by a label thereby to effect pivot movement of said suction pipe means from its label receiving position to its label applying position.
  • a device which includes spring means associated with said suction pipe means and continuously urging the same in effect to its label receiving position.
  • a device which includes deposit means with a deposit plane for receiving a label to be applied to weighed goods, said deposit means being arranged near said label receiving position and being provided with passage means for permitting passage of a portion of said suction pipe means therethrough, and cam means arranged below rest position of said suction pipe means and operable after a label has been deposited upon said deposit plane of said deposit means pivotally to move the suction mouth of said suction pipe means into engagement with a label in said plane so that said suction mouth is closed by said label.
  • suction pipe means comprises two hingedly connected pipe sections adapted from an aligned position therebetween in which an approximately tight connection exists between said two sections to be pivoted against resilient force relative to each other for venting said suction pipe means.
  • a device which includes electrically heatable plate means within the region of said suction mouth for activating an adhesive layer on a label to be applied to goods.
  • a device which includes microswitch means adapted to be connected to the printing and label issuing mechanism of a calculating scale and responsive to said suction pipe means having reached its label receiving position for causing triggering of said printing and label issuing mechanism to print a label and deposit the same released for pickup by said suction pipe means.
