FIG. 7 is an operation explanatory view showing the operation of the support table 16, the mandrel 17, the picker 20, and the top locator 19 when operated in the shrink labeler state, and below the third cam 42 and the switching means. The cam path by the cam plate 44 at 43 is shown.
First, in the lifting mechanism 30 that lifts and lowers the picker 20, the cam plate 44 is lowered so that the third cam follower 41 passes through the lower cam path 42b in the third cam 42.
The label supply means 6 is raised by the elevating means 57 so that the sticking drum 53 is located at the height of the mandrel 17. Further, the UV curing glue application roller 56 moves forward and is in the operating position, and the heating means 55 moves backward and is in an inoperative state.
7A to 7G correspond to the positions or sections shown in FIGS. 1A to 1G, respectively.

First, when the container 1 is supplied to the container supply star wheel 3 via the supply conveyor 7 and the screw 8, the container 1 held in the pocket of the container supply star wheel 3 at the receiving position A in FIG. 5 on a support table 16.
At this time, the top locator 19 is retracted above the container 1 by the first cam 28, and the picker 20 is also retracted to the same height as the mandrel 17 by the third cam 42.
Subsequently, when the rotary table 5 rotates and the container 1 reaches the section B, the top locator 19 is lowered by the first cam 28 and fitted into the mouth of the container 1, and the container 1 is connected to the support table 16 and the top. It is pinched by the locator 19.
Further, the turntable 5 rotates to set the route to the lower route 42b by the switching means 43 at the start position of the section C, that is, the position upstream of the sticking position C1 by the label supply means 6 in the rotation direction. The third cam 42 moves the picker 20 down to the height of the container 1.
At this time, the second cam 36 of the opening / closing mechanism 29 that opens and closes the picker 20 is disposed so as to open the picker 20, thereby forming a gap between the container 1 and the picker 20. .

On the other hand, in the label supply means 6, the shrink label supplied by the feed roller 51 is cut to such a length that the outer periphery of the container 1 is surrounded by the rotary cutter 52 and the front end portion and the rear end portion thereof are superposed. Further, UV curing glue is applied to the rear end portion of the back surface of the shrink label attached to the surface of the sticking drum 53 by the UV curing glue application roller 56 in the vertical direction.
When the container 1 reaches the sticking position C1 with the label supply means 6, the mandrel 17 and the sticking drum 53 are rotated in the opposite directions by the servo motor 18 and the motor 54.
At this time, the suction hole 17a of the mandrel 17 communicates with the suction means via the vacuum passage 24 to suck the shrink label, and the sticking drum 53 releases the suction of the shrink label, and the shrink label is put on the sticking drum. Passed from 53 to the mandrel 17.
The shrink label makes one turn around the mandrel 17, and the leading end portion and the trailing end portion are polymerized. At this time, the UV curing paste applied to the trailing end portion adheres to the leading end portion. Yes.

Subsequently, when the turntable 5 is rotated and the container 1 is moved to the wiping position C2, the mandrel 17 is rotated by the servo motor 18 so that the superposed portion of the shrink label faces the wiping roller 61. .
In this state, the wiping roller 61 approaches the mandrel 17 and presses the overlapped portion of the shrink label from the outside so that the overlapped portion of the shrink label comes into close contact.
Further, the mandrel 17 does not rotate until the turntable 5 rotates and the container 1 moves to the curing position C3, so that the superposed portion of the shrink label faces the UV irradiation means 62.
In this state, when the UV irradiation means 62 irradiates the superposed portion of the shrink label with the ultraviolet light, the UV curing paste is cured, and the front end portion and the rear end portion of the shrink label are bonded to each other on the outer surface of the mandrel 17. A shrink label will be formed.

When the turntable 5 rotates and the container 1 reaches the section D, the third cam 42 raises the picker 20 to the position of the mandrel 17, and the picker 20 has been in an open state until then. In the section D, the second cam 36 is closed.
When the picker 20 is in a closed state, the suction means communicates with the suction hole 20a of the picker 20 to suck the shrink label, and the communication between the suction hole 17a of the mandrel 17 and the suction means is blocked. The shrink label that has been sucked and held in the suction hole 17 a of the mandrel 17 until then is sucked and held in the suction hole 20 a of the picker 20.
Subsequently, when the container 1 reaches the section E, the servo motor 18 rotates the support table 16 at a predetermined speed. In this state, the picker 20 is lowered by the third cam 42, and a shrink label is placed on the container 1. It will be installed.
Here, since the container 1 is rotated by the support table 16, the container 1 is inserted into the shrink label sucked and held by the picker 20 while being rotated, whereby the shrink label is turned up by the container 1. Is to be prevented.
Note that the shrink label may be attached in a state where the container 1 is stopped without rotating.

When the container 1 reaches the section F, the communication between the suction hole 20a of the picker 20 and the suction means is blocked, and the picker 20 is brought into the open state from the closed state by the second cam 36.
When the picker 20 is detached from the shrink label in this way, the picker 20 is subsequently raised to the height of the mandrel 17 by the third cam 42 and retracted above the container 1.
Thereafter, when the delivery position G adjacent to the container discharge star wheel 4 is reached, the top locator 19 is lifted and separated from the container 1 by the first cam 28, and the container 1 is held in the pocket of the container discharge star wheel 4. Then, it is discharged to the discharge conveyor 9.
The container 1 to which the shrink label is attached is then supplied to a shrink tunnel (not shown) and is heat-shrinked so as to be in close contact with the container 1.

Next, the case where the labeler 2 is used in a roll labeler state will be described. FIG. 8 is an operation explanatory view showing the operation of the support table 16, the mandrel 17, the picker 20, and the top locator 19 when operated in the roll labeler state, and below the third cam 42 and the switching means. The cam path by 43 cam plates 44 is shown.
First, in the lifting mechanism 30 that lifts and lowers the picker 20, the cam plate 44 is lifted so that the third cam follower 41 passes through the path 42a above the third cam 42.
When used in a roll labeler state, the label supply means 6 is lowered by the elevating means 57 and the sticking drum 53 is positioned at the height of the container 1 placed on the support table 16.
Further, the heating means 55 is moved forward to be positioned at the operating position, and the UV curing glue applying roller 56 and the wiping roller 61 are moved backward to be positioned at the non-operating position, so that the UV irradiation means 62 is also inactivated. .

Even when the labeler 2 is in the roll labeler state, the container 1 held in the pocket of the container supply star wheel 3 is placed on the support table 16 of the rotary table 5 at the receiving position A, as in the shrink labeler state. The top locator 19 is lowered by the first cam 28 at the position B, and the container 1 is sandwiched between the support table 16 and the top locator 19.
When the roll labeler state is set, the picker 20 does not descend from the position of the mandrel 17 and continues to be retracted upward from the container 1 even after the subsequent C section.
On the other hand, in the label supply means 6, the heating means 55 adjacent to the sticking drum 53 heats the thermally activated glue previously applied to the back surface of the label to generate an adhesive force on the back surface of the label.
When the container 1 reaches the sticking position C1 with the label supply means 6, the servo motor 18 and the motor 54 rotate, and the mandrel 17 and the sticking drum 53 rotate in opposite directions.
As a result, the label is adhered to the container 1 by the activated heat-activatable glue, and the label stuck at this time is affixed to a part of the outer peripheral surface of the container 1 even if it is wrapped around the entire circumference of the container 1. It may be done.
Thereafter, the servo motor 18 stops the rotation of the support table 16, and when the container 1 reaches the delivery position G, the top locator 19 is lifted and separated from the container 1 by the first cam 28, and the container 1 is discharged from the container 1. It is held in the pocket of the star wheel 4 and discharged to the discharge conveyor 9.

As described above, according to the labeler 2 of the present embodiment, the roll labeler that directly attaches the label to the container 1 and the shrink labeler that attaches the shrink label formed in a cylindrical shape from the mandrel 17 to the container 1 are combined. The installation location and cost can be greatly reduced as compared with the case of installing two labelers, a roll labeler and a shrink labeler.
Further, since the label supply means 6 can be moved up and down, the label can be attached to or delivered to both the container 1 and the mandrel 17, so that the single label supply means 6 can be used both as a roll label and a shrink label. .

As for the label supply means 6, if two different label supply means 6 for roll labels and shrink labels are provided and installed at different heights, the elevating means 57 becomes unnecessary.
In this case, if the label supply means 6 for the roll label is a label supply means for supplying a so-called single sheet label in which the label has been cut into a predetermined shape and length in advance, the labeler of this embodiment is a single wafer labeler. It can also be used as a shrink labeler.
In the above embodiment, the support table 16 and the mandrel 17 are driven by a single servo motor 18, but these may be provided on the first plate 13 and the second plate 14, respectively, and driven individually.
Furthermore, in the above embodiment, when forming a shrink label, UV curing glue is applied and the overlapped portion of the label is adhered by irradiating UV, but for example, it may be adhered using hot melt or laser. Good.
In addition, various adhesives can be used to bond the roll label. For example, hot melt can be applied to the front end and rear end of the roll label, and hot melt can be applied to the front end and UV curable adhesive can be applied to the rear end. It is.
In the above embodiment, the shrink label is attached to the container 1 and the shrink label is shrunk in a later process (not shown). However, a heater is provided in the picker 20, for example, in the section E in FIG. It is also possible to heat shrink the shrink label.
