Definitions

  • the invention relates to a device for removing individual objects, in particular weaving, printing and embroidery labels, from an article supply in the form of a stack and for transporting the detected individual objects into a predetermined removal position, the device consisting of a supporting frame with one arranged therein Gripping arm for an adhesive tape made of a strip-shaped carrier with an outside coating of a pressure-sensitive adhesive, which is guided around the free, head-like end of the gripping arm to form a small adhesive surface as an article gripping section, and the support frame in the fastening or articulation area of the gripping arm is an adhesive tape supply roll and carries an adhesive tape take-up roll, of which the adhesive tape take-up roll with a drive device for a continuous or gradual advancement of the adhesive tape for renewal of the respectively incapable article gripping section by an adhesive one n object gripping section is connected.
  • a device for removing individual objects from an object supply in the form of a stack and for transporting the detected individual objects into a predetermined removal position is known from DE-A-2 208 213, which is considered in the preamble of claim 1.
  • a device for picking up and advancing fabric workpieces is described, which should be particularly suitable for moving fabric workpieces from a material supply source, such as a conveyor device, to a feed point in a sewing machine.
  • a material supply source such as a conveyor device
  • an adhesive tape runs over guide members on a protruding arm of the device, the adhesive tape being advanced from one roll of the device to another, so that a fresh part of the tape is used for each take-up and transfer.
  • a workpiece is brought into contact with the belt, for example by means of a lifting device, on which a stack of fabric workpieces is arranged and which lifts all the workpieces until the uppermost workpiece touches the belt.
  • the gripper arm is pivoted with the adhesive tape by rotating about a vertical axis to the input conveyor, the individual workpiece being pulled off the top of the workpiece stack. In this way, the easily sticking workpieces are separated by the sheared removal.
  • the gripper arm is then pivoted about its vertical axis to the input conveyor, on which the workpiece is placed by pulling it off by means of a mechanical device.
  • the workpiece is then transported to a sewing machine by means of the input conveyor device.
  • the gripper arm with its adhesive tape assumes a position inclined to the workpiece stack.
  • the gripper arm can only be pivoted about a vertical axis.
  • the free end of the gripper arm cannot be raised and lowered.
  • the object receiving end of the gripping arm and even after each rotational movement, always lies in one and the same horizontal plane, which is predetermined by the angle of inclination and the length of the gripping arm. Due to this fact, the stack of workpieces must be tracked depending on the decreasing height, that is, raised so that the workpiece located at the top is pressed against the adhesive tape at the end of the gripper arm. The workpiece is therefore not removed from the stack by lowering and lifting the gripper arm.
  • the lifting device for the stack of workpieces and the removal device for the individual workpieces thus form a structural unit that cannot be separated from one another. Since the structural design and arrangement of the gripping arm predetermines the workpiece holding plane and the gripping arm cannot be pivoted in height, the workpiece removing plane is also predefined, which corresponds to the workpiece receiving plane. For this reason, the acceptance position cannot be changed. It is not possible to bring the gripping arm with a workpiece adhering to it into a removal position that is ergonomically advantageous for the seamstress if it is not in the swiveling plane of the gripping arm.
  • Another device for lifting fabrics, fabric parts, in particular nonwovens is known from DE-A-2 157 009.
  • the free end of the gripping arm, over which the adhesive tape is guided is nose-shaped with a large adhesive surface of the section of the adhesive tape lying in the region of the lifting nose.
  • the gripper arm with the lifting lug can be moved via an axis of rotation with a horizontal axis of rotation in an adjustable pivoting range, so that the free end of the gripping arm carrying the lifting lug can be raised and lowered. It is not possible to pivot the gripping arm about a vertical axis in order to bring the picked-up fabric part into a removal position lying in another horizontal plane.
  • This device is designed exclusively so that the top of the fabric part is lifted at one end of a stack to enable the raised fabric part to be pulled off by means of a roller.
  • the stack of fabric parts has to be adjusted so that the fabric part lying on top of it comes to rest in the area of the lifting nose.
  • a device For picking up individual sheet-shaped objects from a stack of sheets, a device is known from US Pat. No. 3,316,877 which is provided with an adhesive finger which has an adhesive-bearing adhesive surface, so that when the adhesive finger is in contact with the sheet to be picked up, it is held on the adhesive finger by means of adhesive force and can thus be transferred into a removal position when the adhesive finger is pivoted.
  • the adhesive force of the adhesive finger is achieved by constantly applying a pressure sensitive adhesive.
  • the disadvantage here is that it is not possible to apply the pressure sensitive adhesive evenly to the gripping surface of the pressure finger.
  • due to the constant renewal of the adhesive layer on the adhesive finger no high work output of this device can be achieved.
  • the invention solves the problem of creating a device for a perfect individual removal of objects, in particular weaving, printing and embroidery labels, regardless of the respective material from which the objects or the labels consist, of an object stack, whereby the removal, filing and presentation process is automatic and the removed individual object is brought into a predetermined removal position lying in any horizontal plane or in an ergonomically favorable position for the seamstress, so that a high work output can be achieved without material losses.

  • the gripper arm 211 is mounted on the slide 205 so as to be pivotable about a horizontal axis and can be pivoted by means of a drive device, then a multiplicity of removal positions can be adopted, the movements of the gripper arm 211 then also being included in the movements of the fully automatically operating device 200.
  • 15 shows four time diagrams in temporal association with one another.
  • Diagram I shows the height h of the slide 205 relative to the day disc 330. This corresponds to the position of the drive device 234.
  • Diagram II shows the Angular position of the support arm 215 relative to the label stack ES, corresponding to the position of the drive device 334.
  • Diagram III shows the output voltage of the sensor 45.
  • Diagram IV shows the speed of advance of the drive device 225 for the pressure-sensitive adhesive tape 20.
  • the slide is first moved from the middle position, which corresponds to the remaining height of the label stack, to the highest position at time A, so that the gripper arm 211 can be freely pivoted. This happened at time B.
  • the drive device 334 is turned on, which rotates the support plate together with the gripper arm 211.
  • the delivery position can, for example, be at an angle of 180 ° with respect to the position of the label stack ES.
  • the microcomputer 340 switches on the drive device 234 in such a way that the carriage 205 moves to a height which is required for the delivery position. As soon as the device 200 has reached the dispensing position (time D), all motors are switched off and the device remains in this position until the label is removed.
  • the output signal of the sensor 45 falls below the threshold value S at time E.
  • the drive device 334 is switched on and shortly afterwards at time F the drive device 234, which moves the carriage 205 to the maximum height, before the gripper arm 211 can reach the area of the label stack.
  • time G carriage 205 has reached the maximum height
  • gripper arm 211 has reached the angular position of the label stack (0 °).
  • the microcomputer switches on the drive device 234 again in order to lower the carriage 205 to the level of the remaining stack of labels.
  • this height is somewhat lower than the height in the previous cycle, which is indicated in FIG. 15 by the height difference d.
  • the output of sensor 45 rises until it reaches a level at time I indicating that the label is adhered. As a result, the drive device 234 is switched off.
  • the microcomputer also counts the number of label dispensing cycles and, after a predetermined number of dispensing cycles (for example 3), transports the adhesive tape 20 by an amount corresponding to the size of the maximum label used.
  • This variable can also be programmed and corresponds to the difference between the times O and P at which the drive devices 225 for the PSA tape are switched on and off.
