Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for attaching a cylindrical shrink label to the body of a pin, and a label attaching guide used directly in carrying out the present invention. be.

[Conventional technology]

As a device capable of achieving the same purpose as the present invention, the Japanese Patent Publication No. 57
There is a publication No.-52276. However, with this conventional product, the holding position of the cylindrical body may shift because it is necessary to transfer the cut cylindrical body from the index table to the front and rear discs with suction cups before attaching the cut cylindrical body to the head of the pin. In addition, the front and rear discs are rotated around a horizontal axis in synchronization with the head of the pin that moves horizontally at a constant speed on a conveyor, and the cylindrical body is inserted into the head of the pin. It is not suitable for attaching a cylindrical body to the body.

However, in Japanese Patent Publication No. 57-33287, a thin and short tube is spread out using a pair of mandrels in the shape of a bisected elliptical cylinder, and the mandrels are positioned above the pin, and then the gap between the pair of mandrels is used. There is a method in which the lifting rod is lowered, or the tube is sucked again with a suction cup and only the tube is lowered, and the tube is fitted into the head of the pin.

However, even in this method, when the tube is transferred from the mandrel to the pin, there is a risk that distortion or displacement of the tube may occur due to the tube separating from the mandrel.

Furthermore, although this method allows the pin to be fitted onto the head, it is not suitable for attachment to the lower half of the body.

[Problem that the invention seeks to solve]

The present invention relates to a method for reliably attaching a heat-shrinkable cylindrical/Nilink label to the body of a pin during one rotation on a rotary table, and its features include: In addition to eliminating the need to transfer shrink labels, when separating the labels by suction, only one side of the label is shifted to create a gap within the label and the label is separated into a cylindrical shape, and this label is attached using a special label attachment guide. A pin link label is attached to the camera.

[Structure of the invention]

The movement of the pins in the present invention is as shown in Fig. 1. The pins transported by the conveyor
After being arranged at a constant pitch by the star foil ■,
Rotary table using center foil as a guide■
The pin lift table is placed at regular intervals on a pin lift table that rotates with the table. After that, the pin lift table is moved up and down as appropriate by a vertical regulation cam, and a heat-shrinkable cylindrical 7-link label is placed on the pin lift table that rotates with the table. ■ is inserted into the body and sent out again by the star foil ■', but since the basic movement mechanism is conventionally known in this type of device, it will not be used in the following explanation. The following describes how the Nilin lapel (2) moves and is inserted into the pin body by the label attachment guide (2) with reference to the schematic diagram shown in FIG. 2.

A...Tubular 7-Yurin label rolled into a roll■
(hereinafter referred to as a label) is lowered from above along the guide (2) and cut into a certain length by the cutter (2).

B. From both sides of the label, the suction plate (Y [phase] It comes into contact with the moving plate 00'.

C... When one suction plate [phase] separates while adsorbing the label, the sliding plates on both sides move forward by different amounts (@) @ ) C. of a flat cylindrical label. A gap is formed in the middle part to facilitate separation of the label.

D...Subsequently, the suction plate is separated along with both sliding plates to open the label into a substantially cylindrical shape.

At this time, the label mounting guide ■ is located below the label, and the claw @ at the tip is closed at the top. (See Figure 5) E: The label attachment guide is raised, the claws are opened, and the label is stretched and held in a cylindrical shape.

F...Pin ■ rises from below and fits inside the nail with the bottom of the pin and the bottom end of the label at the same level.

G...Label clamps (10) on both sides of the label (front and back)
The label is pressed against the body of the pin.

H-: Lower the tab of the label attachment guide while retracting it slightly inward to remove the tab from the label.

Machining: The claw is opened wide below the pin, the adsorption plate [phase] separates from the pin, and the pin descends to the same level as the rotary table with the label pressed by the label clamp (9), then the label clamp 0 leaves.

J... The lifting table 0 that moves the pin up and down has a diameter smaller than the pin diameter, and a protruding plate [phase] is provided in the direction perpendicular to the claw (@back) to prevent the label from falling. In this state, it is sent to the next shrinking process through the star foil ■'.

The steps A, B, C, etc. mentioned above do not correspond to the symbol positions in FIG. These merely indicate the order of steps.

Next, the structure of the label mounting guide will be explained based on FIGS. 3 to 5.

The label mounting guide (2) of the present invention is equipped with a claw (12) made of a thin metal plate whose side surface is approximately trapezoidal and whose plane surface is bent into an arc shape, and a protruding pin (10) is provided on the lower center surface, and the via The concave surfaces of the pawls (22) of a pair of left and right horizontal arms [phase] IU, to which bearings (10) are fixed, are provided so as to face each other. A rotatable support shaft installed on the base plate [phase] that moves up and down by
A horizontal arm is rotatably provided in a horizontal hole (phase) provided in the upper part of the claw 0, and a horizontal arm is biased by a torsion spring (phase) in a direction in which the upper portions of the claws 0 open from each other.

An operating lever (2) is located at the bottom of the horizontal arm of both support shafts (22).
The tips (10) of 2) are placed in a crossed state between the two bearing rings fixed to the protruding pin on the lower surface of the arm, and the rear part of this actuating lever is exposed to the action of the cam as the rotary table rotates. to rotate the shaft (10) and connect the link (1
It is connected to a cam follower [phase] that expands and contracts through 0).

A torsion spring is also provided at the bottom of the operating lever of both support shafts (22), and a rotational force is applied to both support shafts in the direction in which the claws open.

[For production]

Therefore, when the rotary table rotates and the shaft [phase] is rotated at a certain position as shown by the arrow, the cam follower [stock] spreads due to the lick [phase], and when the rear part of the operating lever (22) spreads, the support shaft (10 ) is the fulcrum and the horizontal arm [
phase] and the tip of the actuating lever (22) are caught, and the claws approach each other. At this time, since the tip of the actuating lever [phase] is provided in a crossed shape, the tip [phase] spreads out in the opposite direction, and as this condition progresses, the tip of the actuating lever becomes At [phase], the bearing ■ is pushed outward, and the tips of the claws approach to facilitate insertion of the shrink label.

In the present invention, this label attachment guide (2) is provided above the rotary table (2) in such a way that it moves up and down a certain distance and rotates with each pin (2) in correspondence with each pin (2).
This installation guide ■ rises to pick up the label (7) that has been cut slightly above, and when the claw (22) is expanded and supported by the suction plate [phase], the pin is lifted from below and inserted into the inside of the claw. The body of the pin is inserted, and then the label is pressed against the body of the pin by another label clamp, and the claw is pulled out downwards, so the label does not move at all.

In addition, the pin with the label attached to the body is lowered to the appropriate table position with the label pressed against the pin by the label clamp [phase], so the label is attached to the pin in an extremely stable state, and the next It can be transferred to the heat shrinking process.

〔Effect of the invention〕

In the present invention, as described above, when separating a cylindrical flat label, sliding plates with different movement distances are provided on both sides of one suction plate, and when separating the suction plate, this sliding plate is moved from the label surface. Since the label is moved forward along the label, it is possible to reliably form a gap between the labels that are in close contact with each other, which has the great effect of making it easier to separate the labels thereafter. In addition, the new label attachment guide is compatible with a large number of pins and can be moved up and down while rotating, so even thin, soft labels can be attached securely, as there is no need to change or move the label. Is possible. Furthermore, we adopted a method in which the pin is raised from below with the label opened in an almost cylindrical shape, and then the label is held down and the nail is pulled out, allowing even long labels to be securely attached to the body or lower half of the pin. It is also possible.
