Description

  In the present invention, the label material is formed of, for example, a thin and soft film material, and the adhesive between the label and the liner (tape-like mount) has a relatively strong adhesive force. A label sticker that can be attached to a product by attaching a liner on which a large number of labels are adhered and held and attaching a liner wound up in a disk shape, and then feeding the liner and removing the labels one by one from the liner. The present invention relates to a landing gear.

  2. Description of the Related Art Conventionally, a plurality of techniques are known as a label applicator for attaching a label for printing a price or the like to a product. For example, as a first known example, a feeding mechanism that is operated by a handle operation and feeds out a tape in a predetermined direction, a claw mounting member that is swingably disposed on the front end side of the sticking machine body, and the claw mounting member A claw that is swingably attached to the tip of the tape and that engages with the tip of the label adhered to the tape when the tape is unwound and angularly displaces the claw mounting member, and angular displacement of the claw mounting member Automatically adjusting the tape feeding length fed by the feeding mechanism to match the adhesive pitch of the label, and adjusting the stop lever for stopping the movement of the feeding mechanism, and interlocking with the return operation of the handle A disengagement member for releasing the engagement of the sensing claw at the tip of the label, and the sensing claw is slidable at least in the width direction of the tape and / or the label according to the shape and size of the label to be used. Those configured so as to be displaced (Patent Document 1).

  And by slidably displacing at least in the width direction of the tape and / or label according to the shape and size of the label used by the sensing claw, the sensing claw can be attached to any shape and size. Since it can be moved to match the center position in the width direction of the label, the label can be sent out accurately and timely, and the label can be reliably attached.

  Further, as a second known example, with respect to the basic configuration of the first known example, an adjustment provided with a restricting action unit capable of controlling the return movement amount of the mount (liner) transfer member or the manual lever. In the case of using a label continuum of a type in which a mechanism is added and there is no gap between labels, the mount transfer member or the carrier transporting member determined corresponding to the arrival of the leading edge in the next label with respect to the label sensor Even if the restricting action part of the adjusting mechanism faces the position immediately after the return stop position of the manual lever, and the label sensor cannot detect the arrival of the leading edge of the next label, the return of the mount transfer member or the manual lever The amount of movement is limited by the limiting action part of the adjustment mechanism (see Patent Document 2).

  In addition, since the return movement amount of the backing sheet transfer member or the manual lever is limited by the limiting action part of the adjustment mechanism, even if the phenomenon of undetected arrival of the leading edge of the label occurs rarely, a plurality of movements at a time The label is not peeled off, and troubles due to label jamming are not caused.

  However, in any of the conventional label applicators described above, it is a thin but rigid paper label that prints the price, etc., and the label that has a relatively weak adhesive strength between the adhesive and the liner. When the label material is formed of a thin and soft film material and the adhesive between the label and the liner is relatively strong Is a configuration that cannot be used.

  In other words, if a label made of a thin and soft film material is stuck to the liner with a strong adhesive, the liner that is fed out sequentially by the handle operation is turned at an acute angle with the tapered tip of the peeling member. The label will not peel off from the liner even if it is pulled back. Yes.

  Therefore, even if the label is thin and soft, and sticks to the liner with a strong adhesive, the label is removed from the liner that is fed out sequentially by the handle operation, and the label is placed at the intended position of the target product. It has a problem to be solved so that it can be pasted.

  As a specific means for solving the above-described problems, the present invention has at least a movable handle, and has a function of feeding a liner on which a label is stuck and held by operation of the movable handle, a label pressing member, and a peeling member. The present invention provides a label sticking device, wherein the label pressing member is provided with a resistance function that opposes the direction in which the liner is fed out.

  In the label sticking apparatus of the present invention, the imparting of the resistance function is an improvement in the coefficient of friction or the spring property of the label pressing member itself; and the resistance function weakens the sticking force between the liner and the label, and It is intended to peel off the part as an additional requirement.

  The present invention provides a resistance function to the label pressing member even when it is stuck and held on the liner with a sticky adhesive having a strong adhesive force with a thin and soft label by providing a resistance function facing the direction in which the liner is fed out. By doing so, the label sticking force can be weakened entirely and / or the tip side can be peeled off, so that when the liner is pulled back sharply beyond the tapered tip of the peeling member, the label It has an excellent effect that can be easily peeled off.

It is explanatory drawing which showed schematically the other example of the peeling condition by the label holding | suppressing regarding peeling of the label.

  Next, the present invention will be described in detail based on the illustrated embodiment. First, as shown in FIG. 1 and FIG. 2, the label sticking apparatus 1 has a fixed handle 3a and a movable handle 3b on one end side of the side wall 2, for example, on the rear end side, as in the conventional handler labeler. A tape-like liner 5 wound around a shaft 4 is rotatably disposed near the middle of the side wall 2, and the liner 5 is attached and detached by a support member 6 fitted to the shaft 4. By freely operating the movable handle 3b, the liner 5 is sent to the other end side, for example, the front end side, the front end of the peeling member 7 is turned, reversed to the rear end side, and pulled back, The label 8 that is aligned and held on the liner 5 is peeled off one after another and supplied to a predetermined position of the product to be stuck.

  A bracket 9 is provided on the front end side of the side wall 2, and a label pressing member 10, a label sensing member 11, and a label 8 peeled off from the liner 5 are pressed on the bracket 9 and attached to a target object. A roller 12 is provided. An openable / closable plate-like member 13 for guiding the liner 5 is provided on the bottom side of the side wall 2. Since these structures and the mechanism for feeding the liner 5 by the operation of the movable handle 3b have substantially the same structure as that of the prior art, illustration and description of details thereof are omitted.

  In the label sticking apparatus having such a configuration, for example, the label 8 formed of a thin, soft, transparent or translucent film material or the like and printed with appropriate indications such as characters or designs is relatively. Even when the adhesive 5 is stuck and held on the liner 5 with a strong adhesive, the labels 8 can be securely peeled off one by one so that they can be attached to the intended product.

  Therefore, as shown in FIGS. 3 and 4, in the present invention, the label pressing member 10 acts strongly in the direction (arrow b) that resists the feeding direction (arrow a) of the liner 5, that is, A resistance function for generating a force that interferes with the movement of the label by contacting the label 8 is provided, and a resistance member 14 is provided as an example of the resistance function. As this resistance member 14, for example, a rubber material having a large friction coefficient is suitable. As another example, the spring property of the label pressing member 10 itself is improved.

  As another example, as shown in FIG. 5, a plurality of label pressing members 10a and 10b may be provided, and resistance members 14a and 14b may be provided respectively, or the label pressing members 10a and 10b may be provided. The one with its own springiness is used. The pressing action is applied twice in the direction (arrow b) that is pressed against the label 8 adhered and held on the liner 5 and resists the feeding direction (arrow a) of the liner 5. .

  With this configuration, the liner 5 is sequentially sent out in the direction of arrow a by the operation of grasping and releasing the movable handle 3b, and the stroke of almost one label 8 is sent out by one gripping operation. As shown in FIG. 4, the resistance member 14 of the label pressing member 10 presses and contacts the label 8 and the resistance action in the direction of the arrow b acts strongly on the label 8 as shown in FIG. Two effects reduce the sticking force of the label 8 to the liner 5.

  In this state, the liner 5 is pulled back at an acute angle beyond the tapered tip 7a of the peeling member 7 (the tip is equipped with a thin pipe-like roller), and the adhesive force of the label 8 to the liner 5 is reduced. Therefore, even if the label 8 is formed of a thin and soft resin film material or the like, the label 8 has a slight rigidity, so that the taper tip 7a of the peeling member 7 is provided. When the liner 5 is sharply bent at an acute angle and pulled back, the label 8 is sequentially peeled without following the sharp bend, advances while being sequentially peeled off from the liner 5, and is pressed against an object such as a product by the roller 12. Pasted.

The principle of this peeling will be described with reference to FIGS.
First, as shown in FIG. 6, the liner 5 is subjected to a pulling force in the feeding direction (arrow a), and the label 8 is pressed in the opposite direction (by the pressing contact of the resistance member 14 provided on the label pressing member 10). A force that suppresses or disturbs the movement of the label 8 acts on the arrow b). By the action of both of these forces, as shown by the arrow c, a force in the direction of lifting or peeling acts on the leading end side 8a of the label 8 in the delivery direction of the liner 5, and conversely on the trailing end side 8b. As shown by the arrow d, a force in the pressing direction acts.

  It is estimated that there are two types of effects given to the label 8 by the action of these forces. As shown in FIG. 7, the first effect is that the leading end side 8a of the label 8 is definitely peeled off from the liner 5 and the trailing end side 8b is pressed down by the force in the direction of lifting or peeling off, but the pasting side 8b is pressed. It does not stick strongly beyond the adhesive strength of the adhesive. The length to which the front end side 8a is peeled varies depending on the material of the label 8, the magnitude of the applied force, the position of the action point, and the like, but in principle, the pulling force of the liner 5 and the movement of the label 8 are suppressed or hindered. It is considered to be proportional to the force. Therefore, a force that suppresses or hinders movement may be selected as appropriate.

  As shown in FIG. 8, the second effect is that the sticking surface of the both is displaced over the entire area by the pulling force of the liner 5 in the feeding direction and the force that suppresses or disturbs the movement of the label 8. As a result, innumerable small peeled portions 8c are generated in the entire region, so that the entire sticking strength is weakened and peeling can be easily performed. In this case as well, although it depends on the material of the label 8, the magnitude of the applied force, the position of the action point, etc., it is considered that it is in principle proportional to the pulling force of the liner 5 and the force that inhibits or obstructs the movement of the label 8. It is done.

  Thus, if there are innumerable small peeling portions 8c on the sticking surface of the label 8 and the liner 5, when the liner 5 is pulled back sharply at a sharp tip 7a of the peeling member 7, the label 8 In addition, since there is a certain degree of rigidity, the label 8 with weakened adhesion strength can be easily peeled off without following an acute bend.

  In another example in which a plurality of label pressing members 10a and 10b are arranged, it is not always necessary to attach a resistance member. In short, a strong spring is selected so as to strongly press the label 8, and the label 8 is It is also possible to forcefully push the tip side 8a away with an appropriate frictional force. In this case, the pressing force of the label 8 is weakened by applying a pressing force twice to the label 8, and it is only necessary that the leading end side 8a is separated from the end portion of the label pressing member 10b by the pressing force and is swung up at the same time. Yes, depending on the material of the label 8, a resistance member such as rubber becomes unnecessary.

  In any case, in the present invention, the label 8 is given a force (including a pressing force) that suppresses or obstructs the movement of the label 8 against the pulling force of the liner 5 in the feeding direction, and the leading end side 8a of the label 8 is attached. When the liner 5 is fed out and the taper tip 7a of the peeling member 7 is bent sharply at an acute angle and pulled back, the label 8 can be easily removed. It is intended to be peeled off.

  As explained above, when trying to attach a label to a product, the function of the conventional handler labeler can be used to use a liner that holds the label attached. The label is made of a thin and soft film material so that it can be used even if a sticking agent with strong adhesive strength is used, and it may be widely used. .
