  • the vessel positioning mechanism is operable to provide a constant carrying pitch between the vessels on a conveyer so as to determine a position where a label is attached to the vessel, or a relative labeling position with respect to the labeling drum.
  • the vessels after being positioned at a given interval, are carried to a labeling station.
  • a label magazine provides labels to the labeling drum in sequence.
  • the labels are backed with adhesive by an adhesion roller and then are provisionally affixed to the vessels carried on the conveyer.
  • the labeled vessels are fed to a final finishing section and are pressed moderately by a compression unit.
  • This sequential labeling operation is effected by a driver which is mechanically connected to a single driving source provided in the labeling system.

  • the labeling position is defined by the exact coincidence of the specific point on a label provided on the labeling head with the predetermined position on an article at the labeling station.
  • the third means determines a degree of angular displacement of the rotary labeling drum based on a signal output by the rotary encorder after the labeling head passes the labeling point until another article is sensed by the photo sensor and the degree of angular displacement of the article to calculate a degree of phase shift of the angular position of the rotary labeling drum from the given labeling interval.
  • the fourth means adjusts the rotation of said labeling rotary drum so as to implement said degree of phase shift.
  • a labeling apparatus for attaching labels to a predetermined position on articles which comprises a first means for carrying articles at given carrying intervals to a labeling station, a second means, provided at the labeling station, for attaching a label onto the predetermined position on an article at a given labeling interval, a third means for determining relative positional shift between an actual carrying position and a carrying position coinciding with the labeling interval of said second means and providing a signal indicative thereof, and a fourth means for adjusting the labeling interval of the second means to synchronize with the actual carrying interval based on the signal from the third means in order to attach the label onto the predetermined position on articles.
  • the third means may be include a photo sensor for detecting an article carried by the first means to provide a signal indicative thereof.
  • the third means determines the degree of shift in an actual carrying position from a carrying position which would coincide with the given labeling interval of the second means based on the signal from the photo sensor.

  • a method for attaching labels onto articles carried to a labeling station at given intervals wherein a specific point defined on a label aligns with a predetermined position on an article which comprises the steps of: providing the labels to the articles at given labeling intervals at the labeling station; determining a relative degree of shift between the predetermined position on an article which is being fed and the specific point on a label provided by said providing step; and adjusting the labeling interval based on said relative degree of shift so that the specific point on the label corresponds to the predetermined labeling point on the article.
  • the determining step may include the step of detecting actual carrying positions of the articles to determine a degree of positional shift from the given carrying interval which corresponds to the given labeling interval.
  • the adjusting step adjusts the labeling interval of the providing step at each pitch based on the degree of shift so that the specific point on a label always corresponds to the predetermined position on an article.
  • This system comprises generally an input screw unit 1 functioning as a positioner for vessels 5, a conveyer 2 for carrying vessels, a labeling station 3 for providing a label to the vessels, and compression units 4 for pressing the label attached to the vessel.
  • the vessels 5, such as bottles are positioned by the input screw unit 1 at a given interval and are carried on a belt of the conveyer 2 toward the labeling station 3.
  • the labeling station includes a rotary labeling drum 12, labeling heads 15, an adhesion roller unit 16, and a label magazine 8.
  • the rotary labeling drum 12 is rotatably supported by gearing (not shown) disposed beneath the labeling station and is driven by a drive motor 6 through a gear assembly 20 so as to be mechanically synchronized with the rotation of the input screw unit 1 via a main drive shaft 14.
  • the synchronization determines a carrying pitch between the vessels 5 on the conveyer 2 to provide precise sequential labeling.
  • labeling heads are arranged, for example, at six intervals.
  • the label magazine provides a label to the labeling heads in sequence.
  • the adhesion roller unit 16 provides an adhesive onto the reverse surface of the label provided on the head 15. Thereafter, this label is attached to a given area of a vessel 5 carried by the conveyer 2.
  • an means for compensating for a degree of shift of the vessel with respect to a head of a rotary labeling drum includes a differential gear 13, a servo motor 7 therefor, a photo sensor 10, and a controller 9.
  • the photo sensor 10 is adapted for sensing the position of a vessel carried on the conveyer and to provide a signal indicative thereof to the controller 9.
  • the controller determines the relative degree of shift between each vessel 5, or a predetermined position defined thereon and a corresponding head of a rotary labeling drum 12.
  • the differential gear 13 is driven by a servo motor 7 according to the value of the relative degree of shift.
  • the differential gear 13 is mechanically connected to a gear (not shown) disposed beneath the labeling station 3 via a shaft 22. This gear rotates the rotary labeling drum 12 so as to advance or retard the rotation thereof independent of the drive motor 6 to compensate for any shift in vessel position to maintain accurate label placement.
  • the vessel is pressed by a pair of pads at the compression unit 4 to finish the sequential labeling operation
  • the means further includes a rotary encoder 11.
  • the rotary encoder 11 is installed on the rotary labeling drum 12 so as to monitor an angle of rotation thereof and provides pulse signals of an ⁇ A ⁇ , a ⁇ B ⁇ , and a ⁇ Z ⁇ phase indicative of the angular position of the drum to the controller 9 (As is well known in the art, a rotary encoder is adapted for providing an A phase pulse signal, a B phase pulse signal, and a Z phase pulse signal.
  • the B phase pulse signal is shifted 90 degrees from the-A phase pulse signal.
  • the Z phase pulse signal is a reference signal which is output every cycle).
  • an interface circuit (not shown) for the rotary encoder is provided. This circuit detects the leading edges of pulse signals of the A and B phases.
  • the downcounter receives P number of pulse signals for every cycle of the rotary labeling drum 12 and indicates a value within 0 to -(P-1) (0 to -14399). (Thus, since six labeling heads are provided on the rotary labeling drum, the angle between each corresponds to 2400 pulse signals. These 2400 pulse signals correspond to the carrying pitch of the vessels.)
  • the sensor senses the leading edge of the vessel and provides a signal to the controller 9 to interrupt the CPU.
  • the CPU reads the value of the downcounter and can convert this value into to provide an integer value within 0 to (P-1) (0 to 14339) as the phase angle of the rotary labeling drum 12.
  • the phase difference (R) is the degree of displacement of a labeling head past a labeling point defined by the exact coincidence of the labeling head with the predetermined position of the articles at the labeling station.
  • the number of pulses defining R are counted beginning at the labeling point and ending when the photo sensor 10 encounters the leading edge of the next vessel. (as in Fig. 2)
  • the controller 9 After obtaining the deflection E, the controller 9 provides pulse signals of a number corresponding to the deflection E to the servo motor 7.
  • the servo motor 7 rotates the labeling drum by an angle corresponding to Y number of pulse signals via the differential gear thereby correcting for the shift of a vessel 5 with respect to the corresponding head of the label holder 15.
  • a sequential correction control for phase shift as described above is repeated every carrying pitch and the labeling is thus effected regularly.
  • the CPU breaks off outputting the pulse signals at a predetermined tolerance point in order to protect the mechanical system.
  • the deflection E is small, (e.i., the absolute value of the deflection E is within a certain range ⁇ M ⁇ ) no adjusting operation is provided.
  • the ⁇ Yb ⁇ is a number of the output pulse signals at the previous adjusting operation
  • the ⁇ B ⁇ is a value into which backlash as an error due to reversion of the differential gear 13 is converted and is a proper value defined by the type of differential gears employed.
  • FIG. 3 shows a sensor 30 suitable for box shaped vessels.
  • This sensor is comprised of a light source 32 and a light receiving means 34.
  • the light receiving means includes a plurality of light receiving elements sensitive to the light beam from the light source.
  • the controller 9 can determine the degree of angular displacement of the predetermined position on the vessel in response to the signal output from an element of the light receiving means.
  • Fig. 4 shows a sensor means 40 suitable for cylindrical vessels.
  • a cylindrical vessel such as a bottle usually has a spot 42 for setting its angular position at a positioning section of the labeling system.
  • the sensor means 40 includes a camera 42 and an image measuring apparatus 46 connected to the controller 9. The camera provides an image signal of the spot on the vessel carried on the conveyer 2 to an image measuring apparatus 46.
  • the sensor means 40 can thereby detect angular misregistration of the vessel on the conveyer 2 and, if present, determine the degree of angular displacement thereof.
  • FIG. 5 an angular and positional relationship between the vessel and the labeling head 15 is shown.
  • the shown vessel 5 has been displaced by a distance ⁇ x ⁇ away from the carrying direction and is shifted by a ⁇ - ⁇ angle in the clockwise direction.
  • the distance between the center of the labeling head (i.e., a specific point defined on the label provided on the labeling head) and the point of contact ⁇ C ⁇ or the arc OC is R ⁇
  • the distance between the center of the vessel and the point of contact C, or the arc LC is -r(- ⁇ - ⁇ ).
  • the ⁇ is set up as in the following equation.
  • ⁇ sin ⁇ 1 ⁇ x-(r-z)sin ⁇ / (R+r) ⁇
  • the x corresponds to the previous equation (1).
  • the controller 9 can output Y number of pulse signals to the servo motor 7 to adjust the labeling interval of the labeling drum as necessary so that the specific point on the label aligns with the predetermined position on the vessel.
  • the labeling system according to the invention is adapted for measuring the pitches between vessels carried on a conveyer and/or an angular misregistration of the vessels to calculate a degree of shift between a given labeling area of the vessel and the corresponding labeling head of the labeling drum and for driving a servo motor to adjust the angle of rotation of the rotary labeling drum.
  • the present invention is not limited to the above embodiment of a carrying mechanism for vessels.
  • a differential gear may be provided in a driver for a vessel carrying rotary table 17 and the angle of rotation of the table can be controlled to adjust for phase shift between a vessel and a corresponding labeling head.
