When the adhered column w is manually inserted into the cylindrical holder 6 from the above and the bottom part thereof is placed on the pedestal 20, the photoelectric sensor 3
2 detects this and outputs a signal, and when the output signal is input to the timing control device, the cam motor 27 is started under the control of the control device, and the cam plate 26 mounted on the drive shaft 28 is suspended. It is rotated in the direction of arrow A shown in FIG. As a result, the tip of the lever 23 is rotated downward, the lifting shaft 19 is lowered via the engaging pin 22, and the sticking pillar w mounted on the pedestal 20 of the lifting shaft 19 is lowered. Let When the adhered column w descends in this manner, the photoelectric sensor 33 detects the moment when the upper end of the adhered column w passes, and the timing control device stops the rotation of the cam motor 27 by the output signal. At this time, the rotation of the cam plate 26 is instantaneously stopped by the braking function of the cam motor 27, and the adhered column w is held by the holder 6.
The inside is lowered to a preset height position and stopped.

When the rotation of the cam motor 27 is stopped, the actuating rod 17 of the solenoid 16 is actuated in the pushing direction under the control of the timing control device, and the pair of pressing rollers 11 pivotally supported on the bracket 12 through the rotation of the arm 14.
The a and 11b are rotated in the drive roller 8 direction. As a result, the pressing roller pairs 11a and 11b are respectively pressed from the left and right sides to the vicinity of the upper and lower ends of the adhered column body w, and the adhered column body w is placed on the pedestal 20 by the pressing action of the pressure roller pairs 11a and 11b. Is moved to the drive roller 8 side, and as shown in FIG. 3, part of the adhered column w is pushed out of the opening 7 of the holder 6 and pressed against the drive roller 8. Further, at this time, since the guide groove 21 having a semicircular cross section is provided on the upper surface of the pedestal 20, the adhered column w is smoothly moved to the drive roller 8 side through the guide action of the guide groove 21. A sliding action can be obtained.

Further, the rotary motor 10 includes the solenoid 16
Is started by the control of the timing control device at substantially the same time as the operation of the drive roller 8 and the drive roller 8
Is rotated. Therefore, the adhered column w that is pressed against the drive roller 8 is driven by the drive roller 8 to rotate. In this way, the label supply device 36 is actuated in the state where the sticking pillar w is rotating, and the label 35 at the leading end is fed out in the tangential direction between the drive roller 8 and the sticking pillar w to be stuck. While moving to the column w, the label is completely affixed by being wound around the outer peripheral surface of the column w to be adhered because the column w to be adhered is rotating while being pressed against the drive roller 8. .

Then, when the column w to be adhered rises to the upper limit, the slit 29 of the disk body 30 which rotates in the reverse direction together with the cam plate 26 returns to the position where it coincides with the photoelectric sensor 31, and the photoelectric light passing through the slit 29 is passed. Sensor 31
Thus, the state where the cam plate 26 is returned to the original position is detected, and the cam motor 27 is stopped. This completes a series of operation cycles, and the adhered column w to which the label is adhered can be manually taken out.

In the above embodiment, the photoelectric sensor 32 detects the insertion of the adhered column w, and the detection signal starts a series of controls of the timing control device. Instead of this, it is also possible to provide so that the control is started by a manual switch.
Further, the photoelectric sensor 31 and the slit 29 opening in the disc body 30 are used to detect the state where the cam plate 26 is returned to the original position, but instead, the disc body 30 is provided with a convex portion or a concave portion. At the same time, it is possible to detect by providing a limit switch corresponding to the convex portion or the concave portion. In addition, the bracket 12 that pivotally supports the pressing roller pair 11a and 11b is driven back and forth by the solenoid 16 and the spring 18, and the lifting shaft 19 is driven by the cam plate 26 and the lever 23.
However, the structure for raising and lowering is not limited to this, and any other driving means can be adopted.

[0017]

As described above, according to the present invention, when the columnar body to be adhered is loaded into the cylindrical holder supported in the vertical direction as described above, the elevating drive device drives the pedestal of the elevating shaft downward, and The lowering of the pedestal is stopped along with the ON operation of the upper end detector accompanying the passage of the upper end of the adhered column body by driving, and the advancing / retreating drive device drives the pressing roller pair in the direction of pushing out the adhered column body. Is pressed against a driving roller that is rotating by a rotation motor, and in synchronization with this, the label feeder is driven to supply the label to the surface of the column to be adhered for sticking, and In synchronization with the completion of the predetermined rotation, the advancing / retreating drive device is reversely driven to retract the pressing roller pair to the retracted position, and the elevating / lowering drive control device is reversely driven to raise the pedestal of the elevating / lowering shaft. Therefore, the adhered pillar that is prone to fall, that is, the lip stick Tsu it is possible to adhere the label to the outer peripheral surface thereof an elongated cylindrical body and a bottom portion of such click while retaining the containers such as test tubes with rounded longitudinal direction. Also,
Since the upper end detector that detects the passage of the upper end of the adhered column body that descends due to the downward drive of the lifting shaft and stops the lifting drive device, the diameter and length of the adhered column body differ. It is also possible to attach a label at a fixed height position of the column to be attached, and further, spot attachment or all-around attachment depending on the label size can be performed quickly and reliably.

Further, as described above, since the label can be attached while the column to be attached is held in the vertical direction, it is possible to surely prevent the contents from leaking regardless of the presence or absence of the plug or the cap. This makes it possible to improve workability by eliminating the need for the work of completely closing the caps and stoppers, which was indispensable when tilting sideways as in the past.

Further, according to the present invention, since the sticking work can be carried out for each sticked pillar body, the simplicity can be obtained, and
Since the structure is simpler than that of a conventional fully automatic device, the device can be downsized and can be manufactured at low cost.

Furthermore, since the guide groove having a semicircular cross section is provided on the upper surface of the pedestal along the direction of the driving roller, the column to be adhered can be smoothly slid and the pedestal can be removed from the pedestal. Can be prevented from falling.
