Definitions

  • the present invention relates to a label insert, with a carrier plate for carrying a stack of labels, which carrier plate has an upper surface section on which a respective stack of labels is to be placed, and with a label removal device with at least one drum-shaped member intended therefor is designed to engage with an outermost label of the stack of labels in order to remove and remove the same from the stack, which drum-shaped member has been followed by at least one further label conveyor, and a method for operating the same.
  • Label inserts are used to separate labels arranged in a stack and to feed them to a point at which they are to be connected to an object.
  • Such items can include containers for a liquid, e.g. be a detergent.
  • the longer such containers are made of plastic, the printed paper labels being connected to the container by means of an adhesive.
  • the longer the labels are no longer made from paper but from plastic, in particular the same plastic from which the respective container is made.
  • the labels are connected to the containers by so-called "in mold labeling” (labeling in the mold).
  • labeling labeling in the mold.
  • an already printed label is placed in the injection mold, for example, in which the container is injection molded.
  • the container is injection molded by introducing a plastic mass into the mold, so that there is a cohesive, intimate connection between the label and the injection molded container.
  • in mold labeling as is well known in the art, is also used in plastic blowing and deep-drawing processes.
  • Plastic labels are not as easy as paper sheets, e.g. isolated for printers in word processors. Often, instead of one, several labels are removed simultaneously from the stack to be separated. One reason for this is that the stacks of labels are produced by punching and tend to stick together at their edges, and there may also be dimensional differences depending on the type of punch and the quality. Another major problem arises from electrostatic forces, which occur particularly with plastic films. Another reason is the mechanical properties of the plastics used, which in sheet form are somewhat more problematic than paper.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, achieves the object of providing a label insert and a method for its operation, in which the carrier plate and / or the at least one drum-shaped member between a respective first and second end position relative to one another and are movable away from one another and are arranged such that the geometric plane determined by the upper surface section of the carrier plate in the respective first end position coincides at least approximately with a tangential plane of the drum-shaped member and is at a distance from the tangential plane in the respective second end position.
  • Figure 1 shows a schematic diagram for a general explanation of the operation of the label insert.
  • the label insert has a carrier plate 1 on which a stack 2 of sheet-shaped objects to be separated, here labels, is arranged.
  • the stack 2 lies between a support plate 3 and a stop 4 on the carrier plate 1.
  • the support plate 3 is slidably connected to the support plate 1, i.e. it is connected to the carrier plate 1 via the screw bolts 5 shown, for example, in such a way that it can exert a small pressure on the rear side of the inserted stack 2.
  • the design can be such that the support plate 3 is supported against the support plate 1 by means of compression springs (not shown), as is known to the person skilled in the art.
  • the stop 4 is label-specific, plate-shaped in the exemplary embodiment shown, according to the exemplary embodiment according to the Figures 6-8 has its lower side two obtuse-angled surface sections 6.7.
  • the stop 4 can be rigidly connected to the carrier plate 1 or, as in the exemplary embodiment shown in FIG. 1, the position thereof can be adjusted relative to the carrier plate 1 by means of set screws 8, 9.
  • the height of the stop 4 is selected with the adjusting screw 8, ie the position of its lowermost edge 10 relative to the stack 2, or other working parts of the label insert, which are still to be described. With the adjusting screw 9, the stop 4 can be adjusted in the horizontal direction. This training is also well known to the person skilled in the art. According to the illustration in FIG.
  • the stop 4 is thus connected to a block 28 by means of the screw bolts and carried by the same.
  • This block 28 is connected to the carrier plate 1 via rigid mechanical connecting links. Consequently, the stop 4 is movable together with the carrier plate 1. That is, with a back and forth swiveling movement of the carrier plate 1, the stop performs an up and down reciprocating movement.
  • a suction drum 11 is arranged in the region of the gap between the front edge of the carrier plate 1 and the lower end region of the stop 4.
  • the suction drum 11 has the shape of a hollow body, the wall of which is penetrated by air passage holes 12 and which does not have to be rotationally symmetrical in every embodiment. Furthermore, it can also have, for example, the shape of a hollow truncated cone. These air passage holes 12 are arranged in groups aligned with surface lines of the hollow body, for example drawn.
  • the suction drum 11 is connected to a positionable drive, by means of which the suction drum 11 is rotated and positioned during operation. This drive 13 is controlled by a control unit 33 (FIG. 9).
  • This positionable drive 13 can be a mechanical, have hydraulic or pneumatic structure, may include a servo motor, a DC motor or a stepper motor.
  • the positionable drive 13 has a stepper motor controlled by the control unit 33.
  • the control unit 33 in turn is connected to a clock control device 29.
  • a so-called support 14 is arranged in the interior of the suction drum 11.
  • This support 14 has a single row of suction holes 15.
  • the rotational position of the support 14 within the suction drum 11 is adjustable. Accordingly, it is connected via a rod member 16 to an actuating unit 17, which e.g. contains a set screw. With this, the angular position of the suction holes 15 of the support 14 can be adjusted, i.e. the line-shaped location where the bottom label of the stack 2, as will be described, is sucked onto the suction drum 11.
  • the suction drum 11 and the support 14 are sealed against the environment, so that during operation an optimal suction effect prevails in the respective row of air passage holes 12 in the suction drum 11.
  • the row of suction holes 15 of the support 14 is arranged in the direction of rotation (arrow A) of the suction drum 11 after the zenith, in FIGS. 2-4 in the zenith, that is to say the 12 o'clock position.
  • the best position of the suction holes 15 of the support 14 for operation depends on many factors, e.g. the properties of the objects to be separated, such as their peripheral shape, the location of the lower edge of the stop 4 relative to the suction drum 11, etc. This position of the suction holes 15 is usually determined empirically.
  • the interior of the support 14 is connected to a suction source via a suction line 18 and a line 32.
  • the induced draft can be kept upright or, as shown in the embodiment shown in FIG. 9, for example, the suction line 18 can lead to an on / off valve 19 which is connected to or controlled by the clock control device 19.
  • blowing nozzles 30 are arranged between the support 14 and the stop 4 on both sides of the stack, which are shown purely schematically in FIGS. 5 and 9, from which air streams directed transversely to the inserted stack flow.
  • These blowing nozzles 30 blowing on the edges of the stacked labels are likewise known measures on insert devices.
  • the orientation of the blowing nozzles 30 can be very different, in particular depending on the label shape, and is determined empirically depending on the labels.
  • the compressed air flowing through line 35 is controlled by an on / off valve 31.
  • the bottom label of the stack 2 is drawn onto the surface of the suction drum by the suction pull acting through the suction holes 15 of the fixed support 14 and the air passage holes 12 of the correspondingly positioned suction drum 11 aligned with the suction holes 15, from the stack 2 separated and transported away.
  • This label is then conveyed on by further conveyor devices, for example conveyor belts 20.
  • an embodiment or a method is also provided in which the label removed from the stack 2 is completely wound onto the suction drum and the suction drum 11 itself is moved further and introduces the label into the casting mold, the label only in the casting mold is released from the suction drum 1, which is then moved back to the original position for receiving the next label.
  • the carrier plate 1 extends tangentially to the respective surface of the suction drum, thus in the case of a suction drum in the form of a hollow truncated cone, forms an angle with its longitudinal central axis.
  • transport rollers can also be arranged, e.g. depending on the further handling, processing of the labels.
  • the labels are conveyed into a receptacle 21.
  • This receptacle 21 is e.g. into a plastic blow molding machine, not shown, or its blow mold or blowing tool, where the respective label is inserted and then the object, e.g. Container for a liquid in which mold is poured. This process is known as "in mold labeling".
  • the plastic label becomes a one-piece section of the container.
  • a knife-shaped plate 22 is arranged at the lower edge 10 (Fig. 5-7) of the stop 4, for example.
  • the plate 22 is held in the stop 4 by screw bolts 23.
  • the drawn shape of a projection on the stop 4 forming Plate 22 is only one of the possible designs provided. As a rule, the projection is formed depending on the circumferential shape of the labels in the leading area.
  • the plate 22 can also be formed in one piece with the stop.
  • the plate 22 can further be screwed directly to the stop 4 or otherwise attached thereto, for example by gluing, soldering or welding.
  • the height position of the knife-shaped plate 22 can be selected by the above-described adjustment possibility of the stop 4, that is to say only shown in FIGS. 2-4 for example.
  • edge section of the carrier plate 1 closest to the suction drum 11 does not run in a straight line and parallel to the axis of rotation of the suction drum 11.
  • This edge section is designed in accordance with the outline of the labels in this edge section.
  • projections can also be formed laterally on the carrier plate 1 and also on lateral support plates for the label stack on both sides of the carrier plate 11 and in particular in the region of the front edge thereof.
  • the carrier plate 1 has an extension at the rear, an arm member 24, which is supported on a pivot bearing 25.
  • This arm member 24 is articulated at the end remote from the carrier plate 1 to a transmission rod 26 which is moved to and fro by a drive 27, so that the carrier plate 1 can carry out a pivoting movement against the suction drum 11 and away therefrom.
  • the carrier plate 1 can be fixed, that is to say it can have no arm member 24.
  • the arm member 24 would be connected to the support 14, so that this support 14 with the suction drum 11 can be pivoted against and away from the support plate 1 when the support plate 1 is stationary.
  • the transmission of the swiveling movements from the drive 27 does not necessarily have to take place by mechanical link members, as shown for example. Hydraulic, pneumatic or electrical motion transmission devices are also possible here.
  • the basic control of the label insert is schematic and based on the exemplary embodiment shown in FIG. 9.
  • the reference number 29 denotes the central clock control device, in which a microprocessor is arranged in this embodiment.
  • the clock controller 29 can also e.g. have a mechanical, hydraulic and / or pneumatic structure.
  • the drive control unit 27 controls the clocked pivoting movement of the carrier plate 1 by the clock control device 29.
  • the on / off valve 31 present here is controlled by the clock control device 29 for the supply of the air flowing from the inflow line 35 to the blowing nozzles 30.
  • the on / off valve 19 present here is controlled by the clock control device 29 for the suction train applied via the suction line 32 in the interior of the support 14.
  • control unit 33 (which can be integrated in the clock control device 29) controls the operation of the actuating device, here the stepping motor 13 for the suction drum 11.
  • the associated power supply line is indicated at 34.
  • the clock control device 29 can obviously also be supplied with this current.
  • Figure 2 shows the starting position.
  • the stack of 2 labels is located between the support plate 3 and the stop 4 on the carrier plate 1 that the leading edge of the stack 2 or the bottom label of the same rests on the projecting knife-shaped plate 22.
  • the plate 22 instead of the plate 22, there can be a protrusion shaped in accordance with the outline of the leading edge of the labels, and the end edge of the carrier plate 1 sharpened in the drawing figures can also be shaped according to the said leading edge.
  • the starting position of the stack 2 and the carrier plate 1 after a label has been removed are shown in FIG.
  • the carrier plate 1 is in the swung open end position.
  • the support 14 with the suction drum 11 would be in a position pivoted downwards.
  • both the carrier plate 1 and the support 14 can be moved with the suction drum 11, these would be in the position distant from one another, with the movements depending on the respective drive not necessarily having to be pivoting movements.
  • the suction drum 11 is positioned by the stepping motor 13 controlled by the timing controller 29 such that a row of the air passage holes 12 of the suction drum 11 is precisely aligned with the row of the suction holes 15 of the bracket 14. After reaching this position, the suction drum 11 is stopped. This starting position is shown in FIG. 2.
  • the carrier plate 1 (together with the stop 4 rigidly connected to it) in the position 3 lowered so that the entire stack of labels 2 rests on the suction drum 11.
  • the suction pull acting through the holes 12, 15 of the suction drum 11 or support 14 is applied by actuating the valve 19, so that a first, already releasing force is exerted on the bottom label before the carrier plate 1 is completely lowered .
  • the carrier plate 1 pivots with the rest of the stack 2 upwards, the bottom label now remaining on the suction drum 11 due to the suction pull and consequently the separation from the stack 2 begins. This position is shown in FIG. 4. As soon as the carrier plate 1 begins the upward movement, air jets are blown into the space between the sucked-in labels and the stack 2 which is being raised by the schematically drawn nozzles (see FIGS. 5 and 9).
  • the orientation and location of the nozzle 30 shown in Figures 5 and 9 is only illustrative.
  • the installation position and number of nozzles depends on the properties and the circumferential shape of the labels, in order to achieve an optimal separation effect between the sucked-in label and the stack 2 that is being raised.
  • the suction drum 11 now begins to rotate, as shown in FIG. 5, and now conveys the label away, e.g. to the conveyor belts 20 shown in FIG. 1. As soon as the frictional connection between the conveyor belts 20 and the label takes place, the suction of the still rotating suction drum 11 is released.
  • the suction drum 11 is controlled by the servomotor 13 from the control device 29, rotated again into a position in which a row of air passage holes 12 in the suction drum 11 is aligned with the row of outlet holes 15 in the support 14, that is to say the starting position according to FIG. 2 is reached again.
