DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a label pasting device for pasting labels on bottles with curved surfaces, and an object of the present invention is to provide a semi-automatic label pasting device suitable for pasting labels on a wide variety of small quantities. .

The label pasting device according to the present invention includes a pasting mechanism in which a pasting part and a suppressing part formed of sponge are supported at a required interval and are movable vertically and horizontally; A label mounting table installed at a distance from the pressing part side by the distance between the label mounting part and the pressing part, a glue supply part installed so that the adhesive exudation surface is in a symmetrical position of the label mounting table, and a glue supply part installed so that the adhesive exudation surface has an adsorption surface on the lower surface of the pressing part. It has an air suction pipe that passes through the suppression part so that the mouth is flush with the label, and when the tip of the air suction pipe comes into close contact with the label, the negative pressure inside the pipe attracts the label on the label mounting table, and the label is A label adsorption mechanism that loses label adsorption force by opening a valve in the middle of the piping during pasting, and a label adsorption mechanism that moves the gluing part and the suppression part so that they alternately move up and down on the center line of the bottle setting position. The invention is characterized in that it is equipped with a drive mechanism for causing

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

1 to 3 show an embodiment of the present invention, in which a mounting plate 2 is provided upright on the board/, and the mounting plate 2 is attached to the board/
Two support shafts 3°3 are attached so that they are perpendicular to. The support shafts 3, 3 are fitted with axially slidable members, and two horizontal support shafts s, r are provided between them. A block B which is slidable in the axial direction is attached to the horizontal support shafts J- and t.

As shown in Figure 2, the six sprockets 7 are mounted on the mounting plate in such a manner that they are located between the corners and the vertical sides of the rectangle, and these are roughly gate-shaped. Chain g is hung so that - shafts of the sprockets 7 are connected to rotating shafts of a motor with a reduction gear. A roller 10 is attached to the chain g, and this roller 10
is engaged with the block B. Therefore, the chain g rotates in a fixed orbit due to the rotational force of the motor. In addition, the engagement between the block B and the roller 10 is such that a groove or the like is provided in the block B so that the roller 10 can slide so as to have a predetermined play so that the block B does not move from side to side in the lowered state.

The block t has an arm // protruding from its front side, and a connecting member 7.2 extending in the left-right direction is fixed to the tip of the arm. A pressing portion is held at each end.

The gluing part 3 and the pressing part 3 are made of sponge and have substantially the same shape, and are removable. Depending on the size of the label, a suitable size is selected. The suppressing part /≠ has an air suction tube insertion hole formed in the vertical direction thereof, and the air suction tube /j is inserted and held through the hole so that the lower end surface thereof is flush with the other. In addition, block B has a flow path that opens on three sides, and a valve /
Valve mechanism/6 equipped with Ja is installed. This valve mechanism/
One of the openings of 2 is connected to the suction pipe /j by a flexible tube /7, and the other one is connected to the vacuum pump /i by a flexible tube /lf. That is, a label suction mechanism is composed of a suction pipe /j, a valve mechanism /l, a pump /li, etc., and when the suction port of suction pipe /j is pressed against a label, the negative pressure inside pipe lj is used. Adsorb the label and open the valve/za to lose the adsorption force.

On the other hand, the guide for setting the bottle 20 to which the label is attached is on the board/! / , 22.23 are provided, and a limit switch, 2≠, for detecting the setting of the bottle 2θ is attached to one of the guides, 2.2. The label mounting table 2 is placed at a position where the pressing part/is spaced apart from the bottle setting position by the distance of the pressing part/≠ from the above-mentioned gluing part/3! , and stack the required amount of labels 2 on top of it. Further, the glue supply section 27 is installed so that the glue exuding surface 27a is positioned symmetrically to the label mounting table 2. This glue supply part! 7 is composed of a shallow container 27b and a glue tank 27C, and a large number of micro holes (glue seeping surface 27a) are formed on the top surface of the container 27b by punching or the like, and the glue tank is ,? Communication holes are formed in the bottom surface of 7C, the container, and the top surface of 27b.

Note that an operation control section 2g is arranged on one side of the mounting plate 2. This operation control unit 1 is a power switch 2ga,
It is equipped with a speed changeover switch, etc., and the limit switch 21 is also incorporated into the control circuit, allowing the motor to rotate only when the bottles are set. Further, an actuator 2 for opening the valve 4a is provided near the nut position of the bottle 20.

Next, the operation will be described. Turn on the power switch 21a of the control unit 2J' from 1 to 1 and change the speed changeover switch to a desired speed to prepare for preparation. In this case, the glue tank, 27c
Glue is injected into the mounting table 2j, and a label
4 shall be stacked.

Also, keep the pump/liquid running.

When the bottle 20 is set in the set position in this state, the limit switch 2g operates and the motor rotates.
Chain ♂ moves. The movement of this chain, that is, the movement of block B, causes the gluing part 3 and the pressing part 3 to move along a predetermined route. For example, when the operation is started when the pressing part /l is in the set position as shown in Fig. 1 (a), first the gluing part /3 and the pressing part / μ descends, and the glue and (exit surface, 27a K) oozing glue adheres to the bottom surface of the glued part/3.At this time, the pressing part lt comes into contact with the bottle λ0, but at the start, the label, 2&
(If the action is repeated, a label as shown in the figure,
26 is adsorbed), it simply touches the bottle and the 20 side.

After this, the gluing part/3 and the pressing part/g rise, and as shown in Fig.
Move to the right in the figure as shown in C). The gluing part 3 starts to descend from the point when it reaches the set position, and as shown in Fig. ψ(d)
As shown in the figure, the bottle 20 is glued by the gluing section /3, and at the same time, the tip of the suction tube /j and the pick-up suction port on the pressing section /≠ side come into close contact with the label, 2O, and adsorb it. Then, it rises and moves to the left in the figure as shown in FIG. 7(a). When the suppressing part/g reaches the set position, it begins to descend, and the label 2& is pressed onto the surface of the bottle λO coated with glue, as shown in FIG. J (1)). At this time,
When the valve/Aa comes into contact with the actuator 2 and is in the open state, the label adsorption force is lost. Therefore, the label 2B is firmly glued to the 20th side of the bottle by pressing with the sponge presser/≠. At the same time, glue adheres to the glued portion/3.

Then, it rises again and moves to the right in the figure. At this time, manually remove bottle 2 (1) and insert a new bottle.

Label pasting is performed by repeating such operations. When the number of labels 27 decreases due to repeated visits, a certain amount is secured by adding small amounts.

The shape of the bottle to which the label is attached can be arbitrary, whether convex or concave, but in the case of a round bottle or one with a small curvature, the range of the arc surface is limited to a certain angle or less. In addition, if the dimensions are different, replace the glue part/3 and suppressing part/hiro, guide, 2/~2
3 will be changed in position. This position change can be easily performed by making the mounting hole a long hole.

As described above, according to the present invention, the sponge gluing section and the suppressing section having a label adsorption structure, which are supported at a predetermined interval and are movable up, down, left and right, are moved along a predetermined trajectory to make a bottle. While moving up and down on the position center line, a glue supply section and a label mounting table are provided on both sides of the setting position, so that the glue application or label application to the skin surface and the label suction or glue application section can be performed at the same time, so manual work is not required. It is a simple task to put in and take out bottles and replenish labels. Furthermore, since the position of the guide at the set position can be easily changed, it is possible to easily accommodate bottles with different shapes and sizes, and is suitable for attaching labels to a wide variety of small quantities. Moreover, since the adhesive part and the suppressing part are made of sponge, it is possible to reliably apply a label even to a bottle with a curved surface.
