Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an automatic label wrapping device, and in particular to an automatic label wrapping device suitable for automatically labeling electric wires in order to display the wire type. Regarding attached equipment.

[Conventional technology]

Generally, electric wires used for internal wiring of various control devices and the like are labeled to clarify their type. This is usually done by wrapping a label indicating the wire number around both ends of the wire.

As a device for wrapping a wire number mark label around an electric wire in this manner, an automatic label wrapping device as described in Japanese Patent Application Laid-Open No. 113535/1983 has been proposed.

The automatic label winding device described in JP-A No. 56-113535 has a means for peeling off the label on the sheet, and a means for peeling off the label on the sheet, and a U-shape with the peeled off label in contact with the round object to be wrapped. and a pair of rollers that clamp the wrapped round object via the label. The label is attached in a flag shape and the pair of rotating rollers are rotated in a predetermined direction in the circumferential direction of the electric wire to wrap the label while the electric wire is fixed.

Although such an automatic label wrapping device has the advantage of being able to automatically wrap labels,
There are disadvantageous problems as described below.

[Problem that the invention seeks to solve]

The above-mentioned automatic label winding device uses a chuck method using claws as the label conveyance mechanism, but with such a chuck method, if the label is set out of position, the label is peeled off from the sheet using the claw on one side. There was a risk that the label would be bent relative to the object to be wrapped, or that the label would be damaged by the nails. Furthermore, with the flag-shaped label attachment mechanism in the automatic label wrapping device, when the label is attached vertically and the label is wrapped around the electric wire, the bottom base of the label bulges out and the winding becomes loose. This was far from ensuring that the labels were tightly and automatically wrapped. Therefore, in reality, the work of wrapping the label around the electric wire had to be done manually. For this reason, when the label is manually used, the adhesive surface of the label comes into contact with the fingers, causing problems such as a decrease in adhesive strength and a decrease in wrapping quality.

The present invention has focused on the above-mentioned conventional problems, and aims to provide an automatic label wrapping device that can automatically wrap labels around electric wires and obtain high-quality wrapped products. .

[Means for solving problems]

The present invention, which solves the above problems, provides a device for wrapping a wire number mark label continuously pasted on a tape-like sheet around an electric wire, and a guide roll around which the sheet is wound and a label that comes into contact with the label surface. A label peeling mechanism consisting of a presser foot, a push-up head that is movable up and down on the bottom surface of the peeled label, and a recess that comes into contact with the top surface of the label and into which the tip of the push-up head is inserted to form a concave curved part on the label are provided. It is made up of a suction head that has a suction port opening in a recess so that the label can be moved by suction, and a forming suction moving mechanism that suctions and moves the label, and a forming suction moving mechanism located at the moving end side of this forming suction moving mechanism. a swingable tension plate provided with a wire gripping claw; a wire transfer means for gripping the wire and transferring the gripped wire to a predetermined position in a predetermined order; and the transfer means applies tension. When the wire is transferred to the process position, the wire gripping claws of the tension plate grip the wire and the tension plate pulls the wire, thereby applying tension to the wire between the tension plate and the wire transfer means. A wire tensioning mechanism and a concave curved portion of the label are engaged with the wire to which tension is applied by the wire tensioning mechanism at the moving end side of the shaping attraction movement mechanism. Regarding the label, there is a flag-shape shaping mechanism comprising a pair of shaping plates for adhering the label into a flag-shape, and a pair of elliptical wrapping bodies provided adjacent to the flag-shape shaping mechanism are rotatable in the same direction. At the same time, when rotating, both long axes are rotated synchronously so that they have the same point, and the end face on the long axis side is formed into a rotating surface with a diameter that has the same length as the long axis, and a constant distance is formed between the rotating surfaces. When the elliptical wrapping bodies are rotated so that their long axes become parallel, the label of the labeled electric wire transferred to a predetermined position between both elliptical wrapping bodies by the wire transfer means is transferred to a predetermined position between both elliptical wrapping bodies. It consists of a winding mechanism in which both elliptical winding bodies are wound around the electric wire and bonded near the point where the long axes of the winding bodies coincide with each other.

[Effect]

The wire number mark label, which is continuously peeled off from the sheet by the label peeling mechanism, is formed into an inverted J-shape by the push-up head of the forming suction moving mechanism being inserted into the suction head. The label is moved while being attracted to the head. On the moving end side, the electric wire transferred by the transfer means is first grasped by the electric wire gripping claw of the tension plate that has fallen toward the transfer means side,
The wire is then tensioned between the tension plate and the transfer means by moving the tension plate to the opposite side of the transfer means. In this tensioned state, the electric wire is in a standby state, and when the electric wire is in such a state, the concave curved portion of the label is engaged with the electric wire, thereby making it possible to bond. Thereafter, a pair of shaping plates placed under the electric wires come close to each other and press the hanging parts of the labels of different lengths together, thereby adhering the labels in a flag shape. This labeled electric wire is transferred by the transfer means between a pair of adjacent elliptical winding bodies when the long axes of both winding bodies are in a parallel state, and then transferred in opposite directions between the long axis ends of the elliptical winding bodies. The unbonded portion of the label is rotated by the rotating surfaces of both long axis ends, and the label is wrapped and bonded. Therefore, it is possible to continuously wrap the label with one end in the shape of a flag using a series of mechanisms, and it is possible to automatically perform the wrapping operation with a good winding appearance.

As shown in FIG. 4, the label feeding mechanism 2 has a case 13 having a pair of widthwise variable guides 12 as side walls, and the roll-shaped sheet 8 is loaded on one end side. For this purpose, a groove 14 is formed in the guide 12, and the shaft 15 of the sheet roll is supported in this groove. The sheet 8 is unwound from the roll by a driving means, and guided to the front end side of the case 13 while being regulated by a guide 12. Case 1

Here, in order to forcibly feed sheet 8, the fifth
As shown in the figure, a drive roll 18 is disposed below the guide roll 16. This drive roll 18 has a feed pawl 19 protruding from its outer surface, and correspondingly, feed holes 20 are bored at regular intervals on both side edges of the sheet 8. Drive roll 1
There is a feed guide 2 on the outer surface of the contact area with the sheet 8 of 8.
1 is provided to ensure the feeding action. Further, an auxiliary guide roll 22 is provided between the guide roll 16 and the drive roll 18. Furthermore, the guide roll 16 can be positioned in the sheet feeding direction, and any position can be specified using an optical sensor.

At the front position of the label peeling mechanism 1 of the feeding mechanism 2, there is a forming suction moving mechanism for completely peeling off the label 7 from the sheet 8, providing a curved part on the label, and moving the label a predetermined distance. 3 is provided. The operation of the forming suction moving mechanism 3 will be explained with reference to FIGS. 6 to 9.

First, the operation of completely peeling off the label 7 from the sheet 8 will be explained with reference to FIGS. 6 and 7.

As shown in the figure, the forming suction moving mechanism 3 has a push-up head 23 located on the lower surface side of the label 7 that is partially attached to the sheet 8 and peeled off, and a suction head 24 located on the upper surface side. ing. The push-up head 23 is made of a flat member arranged orthogonally to the feeding direction of the label 7, and is movable up and down. The tip end edge of the push-up head 23 is a semi-cylindrical curved head 25, which comes into contact with the wrapping portion 11 (see FIG. 3) of the label 7 and lifts it upward. On the other hand, the suction head 24 has a recess 26 with a U-shaped cross section formed on its distal end surface facing the label 7, and the curved head 25 can be fitted into the recess 26. The suction head 24 is also able to move up and down,
The label 7 is held together with the push-up head 23 so that the label 7 can be formed into an inverted J shape. In order to form an inverted J-shape, the clamping position is set at a position where the label 7 is offset, and the lengths of the label legs are set to be different while forming a concave curved part by the clamping action at this position. As shown in FIG. 8, the suction head 24 is provided with a suction port 27 that opens into the recess 26, so that the label 7 can be suctioned in a bent state. The suction head 24 is capable of not only vertical movement but also rotational movement, and is capable of transporting the peeled label 7 to another location. Therefore, the suction head 24 and the push-up head 23 are brought close to the label 7 which has been peeled off from the sheet 8 and is in a protruding state from the upper and lower surfaces (FIGS. 6 and 7), and the curved head is placed in the recess 26. 25 to form the curved head 28, the suction port 2

Thereafter, both the heads 23 and 24 are separated, and the suction head 24, which has moved upward, is rotated with the label 7 formed into an inverted J shape (Fig. 8), and as shown in Fig. 9, it is wrapped around the label. The electric wire 29 is moved to a position above the electric wire 29. Then, as shown in FIG. 9, the suction head 24 is lowered to engage the concave curved portion 28 with the electric wire 29, thereby canceling the suction action.

Here, a wire tensioning mechanism 4 is provided to properly position the wire 29 at the moving end of the suction head 24.

10 to 12 are diagrams showing the wire tensioning mechanism 4. FIG.

In the figure, the wire tensioning mechanism 4 has a tension plate 30 pivotally attached to the lower part of the main body of the device, and the tension plate 30 is composed of a flat plate member disposed orthogonally to the sheet feeding direction (see Fig. 1). ), a reciprocating rocking motion is possible as shown in FIG. 11 by a drive means (not shown). A pair of wire gripping claws 31 are pivotally supported on the upper part of the tension plate 30 so as to be able to open and close along the plate surface. The gripping claws 31 form V-shaped notches 32 at an angle θ on opposing lines as shown in FIG. 10A, and can grip the electric wire 29 as shown in FIG. 10B by closing both claws 31. It is said that The electric wire 29 is transported in an extended state in the swinging direction of the tension plate 30. Therefore, the 10th

>), the tension plate 30 is located on the right side of FIG. That is, by rotating in the opposite direction, the wire transfer pallet 33 is moved as shown in FIG.
The electric wire 29 fixed by the upper presser claw 39 is pulled with an appropriate tension, and the electric wire 29 is properly positioned below the moving end of the suction head 24 (FIGS. 9 and 12). In this state, the direction of the recess 26 of the suction head 24 and the axial direction of the electric wire 29 match. Incidentally, tension is applied to the electric wire 29 between a tension plate 30 and a presser claw 39 of the electric wire transfer pallet 33, as shown in FIG. For this purpose, as shown in FIG. 12, the pallet 33 is provided with a presser claw 39 formed with a tapered groove 34 for holding and fixing the electric wire 29, and the narrow part of the tapered groove 34 is used to hold the electric wire 29 during tensioning. is being held in place.

Next, the label 7 is attached to the concave curved portion 28 of the electric wire 29.
This label 7 is temporarily supported by engaging the label 7.
A flag shaping mechanism 5 is provided in order to adhere the flag into a flag shape. This mechanism is located below the electric wire 29 on the moving end side of the suction head 24,
It is formed by a pair of shaping plates 35 (9th
Fig. 13). The shaping plate 35 is a rectangular block mounted on a base 36, and can be driven back and forth toward and away from the electric wire 29 in a direction perpendicular to the electric wire 29. The upper edge of the shaping plate 35 is arranged at approximately the same level as the lower edge of the electric wire 29, and as shown in FIG. It glues them together. This results in a labeled electric wire wrapped in a flag shape as shown in FIG.

Such a labeled electric wire 29 has a winding mechanism 6 consisting of a pair of elliptical winding bodies 37 as a final winding means.
It is something that is being transported rampantly. The elliptical winding body 37 is rotationally driven by a motor 38 (Fig. 1), and the winding bodies 37, 37 arranged above and below rotate in the same direction (Fig. They are rotatable in the direction of arrow A shown in FIG. 16, and rotate synchronously so that there is a point in time when the long axes D coincide as shown in FIG. 16.

In addition, the elliptical wrapped bodies 37, 37 are shown in FIG. 18A,
As shown in Figure B, it can be thought of as a cylindrical body with a diameter d, with the shaded part deleted and formed as shown in Figure 18C, and the long axis end face formed into a rotating surface S with the same diameter D as the long axis. It has been done. In FIG. 18C, the boundary between the end of the rotating surface S and the surface T is actually gently chamfered. On the outer peripheral surface of the elliptical wrapped body 37,
An elastic surface layer portion 40 made of an elastic member such as a rubber material is provided. And the elliptical wrapped body 37,3
When near the state shown in FIG. 16 in which the long axes of the wires 7 coincide with each other, the elliptical winding bodies 37, 37 are arranged so that a spacing slightly narrower than the outer diameter of the electric wire 29 is maintained. Moreover, the surface layer 40 eliminates the misalignment of the label 7, and provides strength suitable for wrapping the electric wire 29 and the label 7.
is prevented from being damaged.

The electric wire 29 is introduced into the intermediate portion of both elliptical winding bodies 37, 37 when their long axes are parallel to each other (15th
(Fig.), is held in place by a wire holding claw 39 provided on the front side. After the labeled electric wire 29 is fixed by the presser claw 39 in this way, rotational power is applied to both the elliptical wrapping bodies 37, 37 so that they rotate in the direction of arrow A shown in FIGS. 15 and 16. When both elliptical winding bodies 37, 37 rotate, both long axis ends of both elliptical winding bodies 37, 37 approach each other as shown in FIG.
While holding the flag-shaped label 7 at the long axis end of
By rotating in the direction, the remaining adhesive surface 10
It is wrapped around.

By this winding mechanism 6, the label 7 is completely wrapped around the electric wire 29 as shown in FIG. 17, and the wire number mark 9 is displayed.

As described above, in the automatic label wrapping device according to the present embodiment, the wire number mark labels 7 are sequentially peeled off by the label peeling mechanism 1, and formed into an inverted J shape by the suction head 24 and the push-up head 24. After that, it can be adsorbed and transferred. Thereafter, the electric wire 29 is pulled to a certain length by the tensioning mechanism 4 and placed, and the label 7 moved by the suction head 24 is retained. Since the concave curved portion 28 of the label 7 is formed in a position offset to one side, adhesive surface portions having different lengths are suspended from the electric wire 29, and the hanging portions are adhered by the flag-shaping mechanism 5, The label 7 is wrapped around the electric wire 29 in a flag shape. Then, the flag-shaped labeled electric wire 29 is completely wound up by the elliptical winding body 37, and the winding work is completed. The electric wire 29 and the label 7 are continuously supplied, and the label wrapping operation is performed continuously by linking the above steps.

According to this embodiment, it is possible to automatically perform the winding work of the wire number mark label 7, which must be done manually, and the winding work can be done in less than 1/3 of the time compared to the conventional method. It became possible. In addition, in particular, the forming suction moving mechanism 3 forms the concave curved portion 28 into a biased position during label suction to form the label 7 into an inverted J-shape, so that the label 7 is not misaligned during transportation and does not fit onto the electric wire 29. There is no deviation when Furthermore, since the electric wire 29 is under tension in the standby state,
It becomes possible to cover the label 7 stably and reliably,
Wrapping during flag shaping can also be done reliably. Therefore, there is no bulge at the base of the neck or incomplete wrapping. In addition, since the surface layer 40 of the winding mechanism 6 is made of an elastic material, there is no risk that the label 7 will shift during winding, and the label 7,
This has the advantage of not causing damage to the electric wire 29.

〔Effect of the invention〕

As explained above, according to the present invention, since tension is applied to the electric wire in the standby state, it is possible to stably and reliably cover the label with the electric wire, and the standby state for wrapping can be achieved by simply rotating a pair of elliptical wrapping bodies. This has the advantage of simplifying the configuration. In addition, according to the present invention, the wire number mark label can be wrapped around the electric wire automatically, stably, and reliably, and there is no need for rework as in conventional automatic label wrapping devices. This has the excellent effect of improving work efficiency and making it possible to obtain high-quality wrapped products.
