Description

  The present invention relates to a label mounting apparatus for mounting a cylindrical stretch label or a shrink label on a mounted body such as a bottle or a bottle.

  For example, as a label mounting apparatus for mounting a cylindrical stretch label on the outer peripheral surface of a body of a bottle such as a PET bottle as a beverage container, there is a rotary type label mounting apparatus having a plurality of mounting heads. As shown in FIG. 12 (a), a pair of openable arms having a suction portion at the tip, which preliminarily opens a cylindrical stretch label L supplied in a folded state in a sheet shape. 61, a pair of openable claws 62 that can open and close the stretch label L opened by the opening arm 61 larger than the outer diameter of the bottle B, and a cylindrical shape that is widened to a predetermined state by the widen claws 62 A pair of openable and closable gripping arms 63 sandwiching the stretch label L between the expansion claw 62, a bottle mounting table 64 for mounting the bottle B, and a bot mounted on the bottle mounting table 64 And bottle gripping arms 65 for gripping a body portion of the B is provided.

  In the label mounting apparatus configured as described above, the cylindrical stretch label L is mounted on the bottle B as follows. First, as shown in FIG. 12A, the opening arm 61 receives and holds the cylindrical stretch label L that is folded into a conveyed sheet shape. At this time, the bottle B on which the stretch label L has already been attached in the previous step is placed on the bottle mounting table 64 in a state where it is gripped by the bottle gripping arm 65. It is located below the bottle B.

  Next, as shown in FIG. 5B, the opening arm 61 that sucks and holds the stretch label L is gradually opened while the stretch label L folded in a sheet shape is gradually opened. At this time, after the holding of the bottle B by the bottle holding arm 65 is released and the bottle B to which the stretch label L is attached is carried out, the expanding claw 62 and the holding arm 63 are raised.

  When the label mounting head 10 reaches the bottle supply position γ, the stretch label L can be inserted with the expanding claw 62 positioned immediately below the stretch label L as shown in FIG. The bottle B is gripped by the bottle gripping arm 65 after the new bottle B is mounted on the bottle mounting table 64. At this time, the expanding claw 62 is in a fully closed state, and the gripping arm that operates in reverse is in a fully open state.

  Subsequently, as shown in FIG. 4D, the expanding claws 62 inserted into the stretch label L opened in a predetermined state gradually open, and as shown in FIG. After the lower end portion of the stretch label L is sandwiched between the opening arm 61 and the expanding claws 62, the opening that sandwiches the lower end portion of the stretch label L as shown in FIG. 13 (f) (FIG. 13 (f)). The arm 61 and the expansion claw 62 are further opened, and the expansion claw 62 is fully opened. At this point, the lower end portion of the stretch label L has been expanded larger than the outer diameter of the bottle B by the expanding claws 62, and the expanded lower end portion of the stretch label L is in the fully opened state. Since the grip arm 63 in the fully closed state is gripped from the outside so as to be sandwiched between the claws 62, the stretch label L is held by the spread claws 62.

  Subsequently, as shown in FIG. 6G, the expanded claw 62 and the gripping arm 63 that are held in a state where the lower end portion of the stretch label L is expanded are lowered, so that the expanded stretch label L is expanded. The lower end of the bottle B is fitted into the head of the bottle B and, as shown in FIG. 9 (h), the bottle gripping arm 65 is opened widely to retract from the movement path of the expanding claw 62 and the gripping arm 63. When the expanding claws 62 and the holding arms 63 holding the stretch label L are further lowered, the stretch label L is completely inserted into the body of the bottle B.

  In this way, when the stretch label L is inserted into the body of the bottle B, the bottle gripping arm 65 again moves the body of the bottle B into which the stretch label L is inserted as shown in FIG. After grasping and releasing the holding of the stretch label L by slightly closing the expanding claw 62 and slightly opening the holding arm 63, the expanding claw 62 and the holding arm 63 are moved as shown in FIG. By descending below the bottle B, the expansion claws 62 are extracted from the stretch label L, and the stretch label L is completely attached to the body of the bottle B. In addition, at the time of extracting the expansion claw 62 from the stretch label L, the stretch label L is held by the bottle B by the bottle gripping arm 65 gripping the body of the bottle B as described above. When the spread claw 62 is extracted from the label L, the stretch label L does not shift downward.

JP 2002-284130 A

  By the way, in the label mounting apparatus as described above, the expanding claw 62 extracted from the stretch label L inserted into the body of the bottle B descends as it is and retracts to the lower side of the bottle B. Therefore, until the bottle B is unloaded after the stretch label L is attached to the bottle B, the bottle gripping arm 65 only grips the upper side of the bottle B, and the lower part of the bottle B is free. The bottle B may be tilted.

  In particular, when a stretch label is inserted into an empty bottle that is not filled with the contents, the bottle itself is lightweight, so that there is a problem that it is easy to tilt and cannot be carried out in a stable state.

  Then, the subject of this invention is providing the label mounting apparatus which can carry out the to-be-mounted body with which the label was mounted in the stable state.

  In order to solve the above-mentioned problem, the invention according to claim 1 can be opened and closed so that a cylindrical label expanded in a predetermined state by an openable / closable expanding claw is sandwiched between the expanded claw. After the label is inserted into the mounted body while being gripped from the outside by a gripping arm, the expanding claw and the gripping arm release the label and release the label from the label In the label mounting apparatus in which the label is mounted on the mounted body by pulling out the nail, after the expanding claw is extracted from the label, the mounted body on which the label is mounted is unloaded. In the meantime, it is an object of the present invention to provide a label mounting apparatus in which the expanding claws can regulate the position of the mounted body. Note that “position restriction is possible” here means that the mounted body is supported when the mounted body is about to fall down, regardless of whether or not the expanding claw is in contact with the mounted body. This includes a case where the mounted body is actively gripped so as not to fall down.

  As described above, in the label mounting apparatus according to the first aspect of the present invention, after the spread claw is removed from the label inserted into the mounted body, the expanded body is carried out until the mounted body with the label mounted is carried out. Since the position of the mounted body can be regulated by the opening claws, even if the mounted body itself is lightweight, it can be carried out in a stable state without being inclined.

  Hereinafter, embodiments will be described with reference to the drawings.

It is like that.

  Since the label mounting apparatus 5 configured as described above basically performs the same operation as the conventional label mounting apparatus shown in FIGS. 12 and 13, the description of the operation of the label mounting apparatus 5 is omitted. An operation peculiar to the mounting device 5 will be described with reference to FIG. The opening arm 61, the expansion claw 62, the gripping arm 63, the bottle mounting table 64, and the bottle gripping arm 65 in the conventional label mounting apparatus shown in FIGS. It corresponds to the opening claw 34, the holding arm 35, the bottle mounting table 51, and the bottle holding arm 52, respectively.

  In the conventional label mounting apparatus, as shown in FIGS. 13 (i) and 13 (j), when the stretch label L is inserted into the bottle B, the spread claw 64 is pulled out from the stretch label L and immediately more than the bottle B. In this label mounting device 5, when the label L is inserted into a predetermined position of the bottle B as shown in FIGS. 10 (a) and 10 (b), the spreading claw is expanded. The label L is attached to the bottle B by pulling out the label 34 from the label L. After the expansion claw 34 is extracted from the label L, the expansion claw 34 is not immediately lowered to the lower side of the bottle B. As shown in FIGS. 3C and 3D, the expansion claw 34 is temporarily stopped at the lower part of the bottle B (below the label L), and the bottle B with the label L attached immediately before the bottle delivery position δ. When it is transported to the position, (E), and is adapted to drop as shown, the expansion claws 34 on the lower side of the bottle B (f).

  Further, when the stretch label L is inserted into the body of the bottle B with the lower end of the stretch label L held by the widening claw 34 and the grip member 36, the stretch label L with respect to the outer peripheral surface of the body of the bottle B Since the tip end side of the grip arm 35 (35a, 35b) supporting the grip member 36 tends to be lifted by the contact resistance of the label mounting device 5, the opening / closing arm 33 is used as shown in FIGS. The upper side of the mounting portion of the gripping member 36 so that a slight gap is formed between the upper surface of the mounting portion of the gripping member 36 to the gripping arm 35 when (33a, 33b) is opened to the maximum. By attaching the locking member 30a protruding to the open / close arm 33 (33a, 33b), the lifting end of the grip arm 35 (35a, 35b) is prevented.

  As described above, in this label mounting device 5, after the expansion claw 34 is extracted from the label L inserted into the bottle B, the expansion claw 34 is extended until the bottle B mounted with the label L is carried out. Since the position of the lower part of the bottle B can be regulated, even if the bottle B itself is light like an empty bottle not filled with the contents, it can be carried out in a stable state without tilting. .

  In the above-described embodiment, the case where the stretch label L is attached to the bottle B has been described. However, the label attachment device 5 is not limited to the case where the stretch label L is attached to the bottle B, but also a cylindrical shrink label. It can also be used when attached to a bottle.

  In addition, as described above, when the spread claw 34 spreads the label L, the label mounting device 5 has the opening arm 21 that opens the label L in a folded state in a sheet shape. The lower end portion is sandwiched between the expanding claws 34 and the suction operation by the opening arm 21 is continued until the label L is sandwiched between the expanding claws 34 and the opening arm 21. Therefore, the label L is securely held by at least the opening arm 21 or the expanding claw 34 until the label L is expanded from the folded state to a predetermined state. There will be no deviation. Therefore, the cylindrical label L can be securely attached to the predetermined position of the bottle B, and the label (printing / design) with respect to the circumferential direction of the bottle as in the case of attaching the cylindrical shrink label to the square bottle. ) Is particularly effective when the mounting position is determined to some extent.

  Further, in the above-described embodiment, the open / close arm 33 having the expanding claws 34 is opened and closed by the open / close driving means 37 so that the grip arm 35 is operated in reverse, but the present invention is not limited to this. It is also possible to reversely operate the expanding claw 34 by opening and closing the grip arm 35 side.

  In the above-described embodiment, the open / close arm 33 to which the expansion claw 34 is fixedly installed is swung. However, the present invention is not limited to this. For example, FIGS. 2), the cam base 335 of the expanding claw 334 is supported so as to be able to advance and retract along the guide portion 336, and the cam follower 335a attached to the mounting base 335 of the expanding claw 334 is formed on the opening / closing arm 333. The expansion claw 334 can be moved in parallel by fitting in the hole 333a and swinging the opening / closing arm 333. Further, the gripping arm 35 having the gripping member 36 is not necessarily required to reversely move with respect to the opening / closing arm 33 having the expanding claws 34, and may be fixed.

  Moreover, in embodiment mentioned above, after unfolding the expansion nail | claw 34 from the label L inserted and inserted into the bottle B, until the bottle B with the label L attached is carried out, the expansion nail 34 is the lower part of the bottle B. However, the portion of the expansion claw 34 that can be position-regulated is not limited to the lower part of the bottle B.

  In this embodiment, the case where the stretch label is attached to the PET bottle has been described. However, the attachment object is not limited to the PET bottle as described above. The present invention can be applied to a case where a stretch label or a shrink label is attached to various containers or cylindrical bodies such as the above.
