Therefore, the four open / close rods 28 are not all closed in the same manner, but as shown in FIG. 3, the open / close rod 28b having a short distance D has a larger closing amount than the open / close rod 28a having a long distance D. As shown in FIG. 2, the entire opening / closing rod 28 can be closed so that the tip of the opening / closing rod 28b having a large closing amount is surrounded by the tip portion of the opening / closing rod 28a having a small closing amount. The tip of the can be made thinner.
[0026]
As shown in FIG. 2, the cam mechanism 31 has a cylindrical body 32 having three cam grooves 32a, 32b, and 44 (see FIG. 5) disposed so as to surround the upper half of the rotary feed base 10. And rollers 33 and 34 respectively supported by the upper end portions of the support member 24 and the operating rod 25, which are fitted into the cam grooves 32a and 32b of the cylindrical body 32, respectively. By rotating the rotary feed base 10 and moving while moving up and down along the cam grooves 32a and 32b, the support member 24 and the operation rod 25 on which these rollers 33 and 34 are supported are moved up and down, respectively. ing.
[0027]
The label insertion means 40 includes a support bar 41 supported so as to be movable up and down along the rotary shaft 11 via the support arm 13, a label pushing plate 42 attached to the lower end portion of the support bar 41, and a support bar. And a cam mechanism 43 for raising and lowering 41.
[0028]
The label pushing plate 42 is formed with holes (not shown) through which the entire four opening / closing rods 28 are inserted, and the label pushing plate 42 descends along the opening / closing rod 28, The label L opened in a predetermined state is pushed downward and is inserted into the body of the bottle B located immediately below the label L.
[0029]
The cam mechanism 43 includes a cam groove 44 formed in the cylindrical body 32 and a roller 45 that is fitted in the cam groove 44 and supported by an intermediate portion of the support bar 41. By moving the rotary feed base 10 while moving up and down along the cam groove 44, the support bar 41 on which the roller 44 is supported is moved up and down.
[0030]
As shown in FIG. 2, the rollers 33 and 34 and the roller 44 are supported by the support member 24, the operation rod 25, and the support rod 41 via the attachment members 35 and 36 and the attachment member 46, respectively. The attachment members 35 and 36 are slidably supported by the support rod 41 and the attachment member 46 is slidably supported by the support member 24, and the long support member 24 and the support rod 41 support each other to support each other. Increases stability.
[0031]
As shown in FIG. 1, the rotary type label insertion device 5 configured as described above has a cylindrical label L that is folded into a sheet that has been conveyed to the label delivery position β by the label delivery device 4. However, at this time, as shown in FIG. 5A, the support member 24, the operation bar 25, and the support bar 41 are all in the uppermost position. The opening / closing rod 28 and the label pushing plate 42 in the closed state are located above the label L held by the label holding means 21. At this time, below the label L held by the label holding means 21, the label L is already inserted into the body, and the bottle B delivered to the bottle conveying device 6 at the bottle delivery position δ is the container holding table. 14 is supported.
[0032]
Subsequently, at the bottle supply position γ, the bottle B supplied by the bottle supply device 2 is received and held on the container holding base 14. However, during the period from the label delivery position β to the bottle supply position γ, FIG. As shown in (b), when the clamping member 22 is opened, the label L adsorbed by the clamping part 22a is held in a preliminarily opened state.
[0033]
Next, as shown in FIG. 4C, the rollers 33 and 34 are similarly lowered along the cam grooves 32a and 32b, so that the support member 24 and the operation rod 25 are similarly lowered and opened and closed. The collar 28 is inserted into the label L preliminarily opened by the label holding means 21 while maintaining the closed state. Thereafter, as shown in FIG. 4D, the roller 34 descends along the cam groove 32b, so that only the operating rod 25 descends. As described above, the opening / closing rod 28 is opened, so that the roller 34 is opened preliminarily. The label L is opened in a predetermined state.
[0034]
Then, as shown in FIG. 5E, the label holding means 21 releases the suction, and the rollers 33, 34 and 45 are slightly moved along the cam grooves 32a, 32b and 44 while maintaining the relative relationship. By lowering, the open / close bar 28 and the label pushing plate 42 in the opened state are slightly lowered, and the lower end of the open / close bar 28 reaches the head of the bottle B held by the container holding base 14 together with the label L. .
[0035]
Here, as shown in FIG. 5F, when the roller 45 descends along the cam groove 44, only the support bar 41 descends, and accordingly, the label pushing plate 42 descends along the opening / closing rod 28. Therefore, the label L opened in a predetermined state is pushed downward by the label pushing plate 42 and is inserted into the body portion of the bottle B.
[0036]
Finally, as shown in FIG. 5G, the rollers 33, 34 and 45 are moved up along the cam grooves 32a, 32b and 44 while maintaining the relative relationship, so that the opening / closing rod 28 is opened. The label L is raised together with the label pushing plate 42 while being maintained, and the insertion of the label L into the bottle B is completed.
[0037]
As described above, the bottle B in which the cylindrical label L is inserted into the body in this manner is delivered to the bottle transport device 6 at the bottle delivery position δ, and the bottle L is transported by the bottle transport device 6. It is conveyed to a heating device (not shown) for heat shrinking.
[0038]
As described above, the rotary type label insertion device 5 is a label in which the opening of the label L and the insertion of the label L into the bottle B are performed by the support member 24 that moves up and down, the operation rod 25, and the support rod 41. By employing the opening device 20 and the label insertion means 40, the label opening device 20 and the label insertion means 40 can be installed in an empty space immediately above each container holding base 14, and the structure is complicated. It is possible to realize a compact rotary type label insertion device that does not become necessary.
[0039]
Further, as described above, the label opening mechanism portion 26 is provided with two types of opening / closing rods 28a, 28b having different closing amounts alternately, so that the front end portion of the opening / closing rod 28 in the closed state can be more laid. When the label opening mechanism portion 26 is inserted into the cylindrical label L that has been preliminarily opened by the label holding means 21, the closed opening / closing rod 28 is more reliably inserted into the label L. Thus, the frequency of occurrence of poor insertion of the label L can be kept extremely small.
[0040]
Further, as described above, the label opening device 20 and the label insertion means 40 mounted on the rotary type label insertion device 5 raise and lower the support member 24, the operation rod 25 and the support rod 41 by the cam mechanisms 31 and 43. Therefore, it is not necessary to separately provide driving means for raising and lowering them.
[0041]
In the above-described embodiment, the opening / closing rod 28 is opened when the operating rod 25 is lowered, and the opening / closing rod 28 is closed when the operating rod 25 is raised. If the thick taper portion 30a can be formed, the opening / closing rod 28 can be closed when the operating rod 25 is lowered, and the opening / closing rod 28 can be opened when the operating rod 25 is raised.
[0042]
In the above-described embodiment, the four opening / closing rods 28 are disposed. However, the number of the opening / closing rods 28 is not necessarily four, and the number may be appropriately set depending on the size and shape of the label L. However, as described above, when two types of opening / closing rods having different closing amounts are alternately arranged, it is needless to say that the number of opening / closing rods should be set to an even number.
[0043]
In the above-described embodiment, the case where the label to be inserted into the bottle is a shrink label has been described. However, by making the opening / closing bar 28 slippery with respect to the label, the label can also be applied to a stretch label.
[0044]
【The invention's effect】
  As described above, the present inventionIn the rotary type label insertion device,The label is opened in a predetermined state by raising and lowering both the support member attached with the label opening mechanism having an opening / closing rod and the operation rod for opening the label opening mechanism.Because it uses a label opening deviceIn a rotary type label insertion device that receives and inserts a label while transporting the container while it is held on the container holding table, the label opening device is generally directly above each container holding table having an empty space. By installing each, it is possible to realize a compact rotary type label insertion device that does not become structurally complicated.
[0045]
In particular, a cam mechanism that opens the closed opening / closing rod outward by raising and lowering the operating rod is provided with a tapered portion formed on the operating rod and an opening / closing rod that contacts the outer peripheral surface of the operating rod including the tapered portion. In a configuration in which two types of opening / closing rods having different distances between a support point with respect to the base portion and a contact point of the roller with respect to the outer peripheral surface of the operation rod are alternately arranged, Since the tip of the entire open / close bar in the closed state can be made smaller (thinner), the open / close bar in the closed state can be removed when inserting the label opening mechanism into the preliminarily opened cylindrical label. Insertion into the label can be performed more reliably, and the frequency of occurrence of defective insertion of the label can be suppressed extremely low.
