[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an apparatus for attaching a band-shaped cushioning material to a door or a lid, for example, when sealing a door or a lid of various containers. About.

[0002]

2. Description of the Related Art For example, when a band-shaped cushioning material is adhered to a door or a lid and sealed, an operation of bonding a band-shaped cushioning material having an adhesive layer formed on one side to a predetermined mounting portion while peeling off release paper is used. It is carried out.

[0003]

[Problems to be solved by the invention] However, the cushioning material must be adhered along a predetermined curve,
Since the attachment portion may be formed with a curved surface, it is very difficult to accurately attach the cushioning material to a predetermined position, and the attachment is often shifted. If the cushioning material is displaced and adhered, not only the appearance is poor, but also, for example, when used as a seal for a lid or the like, a sealing property is not obtained,
There is a possibility that it will be defective. Also, in order to repair the displacement of the cushioning material, if the strip-shaped cushioning material once adhered is peeled off and then re-applied, the adhesive strength will be weakened, and after shipping as a product, the sealing material will be easily peeled off during use. Product failure.

[0004] The inventor of the present invention inspired the technique of adsorbing and transporting a glass plate or a tile with air, and adsorbing the band-shaped cushioning material to a jig having a shape corresponding to the cushioning material mounting portion. We experimented with a means to securely and easily attach the cushioning material, but high-rigidity glass plates and roof tiles can block all the air intake holes at the same time and can be easily absorbed, but they are used for cushioning materials The high elasticity material is too soft to block all the air intake holes at the same time, and at the same time, even if it is sucked, a small gap is easily formed and it easily peels off, so it is impossible to hold the cushioning material after all Was.
Therefore, it is a technical object of the present invention to ensure that the band-shaped cushioning material can be reliably held and accurately positioned, and that the band-shaped cushioning material can be securely bonded to a predetermined mounting portion.

[0005]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention is an apparatus for attaching a band-shaped cushioning material to a cushioning material attaching portion of a work positioned at a predetermined position. A holder for holding the band-shaped cushioning material in a state where the adhesive layer formed on one surface thereof is exposed is disposed so as to be able to advance and retreat with respect to the cushioning material mounting portion, and the holder has a band-shaped cushioning material. A buffer material holding groove equal to the width and shallower than its thickness is formed in a shape corresponding to the buffer material attaching portion, and an intake hole for adsorbing the band-shaped buffer material is formed at the groove bottom, and a peripheral portion of the intake hole is formed. Is formed to protrude from the groove bottom so that the suction hole can be in close contact with the band-shaped cushioning material. After the cushioning material is fitted into the cushioning material holding groove, the holder is advanced to attach the cushioning material to the mounting portion. Until it absorbs air from the air intake hole to hold the cushioning material in the holder. Characterized in that it comprises an intake device for wearing.

[0006]

According to the present invention, for example, the release paper adhered to the adhesive layer is fixed, the holder is lowered from above the band-shaped cushioning material, the cushioning material is fitted into the cushioning material holding groove, and the suction device is turned on. Then, air is sucked from the suction hole at the bottom of the groove, and the band-shaped cushioning material is sucked. The peripheral portion of the intake hole is formed so as to protrude from the groove bottom, and when the cushioning material is fitted, the peripheral portion is pressed against the band-shaped buffer material so that the intake hole and the band-shaped buffer member are in close contact with each other. When the is sucked, the band-shaped cushioning material is firmly adsorbed and does not come off even if some external force is applied.
At this time, the cushioning material holding groove is formed to be shallower than the thickness of the cushioning material, so that the adhesive layer of the cushioning material protrudes out of the groove,
In this state, when the holder is advanced to the buffer mounting portion of the work, the adhesive layer of the band-shaped buffer is pressed against the buffer mounting portion of the work and is securely bonded. Further, since the cushioning material holding groove is formed in a shape corresponding to the mounting portion, there is no displacement. Next, after the band-shaped cushioning material is adhered to the work, the suction device is turned off and the holder is retracted, and the cushioning material is easily detached from the holder while being adhered to the mounting portion, and the bonding operation is completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be specifically described based on embodiments shown in the drawings. FIG. 1 is a flow sheet showing an example of the present invention, and FIG. 2 is a cross-sectional view showing a main part thereof.

In FIG. 1, reference numeral 1 denotes a holder for holding the band-shaped cushioning material 2 on which the adhesive layer 2a is formed, with the adhesive layer 2a facing up. The positioning device 6 is provided so as to be able to move forward and backward between the buffer material mounting portion 4 of the positioned work W and the belt-shaped buffer material supply device 5. The band-shaped cushioning material supply device 5 includes, for example, a release paper 2 on which the band-shaped cushioning material 2 cut to a predetermined width is adhered.
b is intermittently transported by the suction conveyor 5a, and
Is positioned at a predetermined position. The positioning device 6 of the holder 1 includes a reciprocating device 7 for reciprocating between the cushion mounting portion 4 and the band-shaped buffer supply device 5, and a reciprocating device 7.
And a cylinder 8 for moving the holder 1 moved up and down.

The holder 1 has a buffer material holding groove 9 which is equal to the length and width of the band-shaped buffer material 2 and is shallower than the thickness thereof, is formed in a shape corresponding to the buffer material mounting portion 4 of the work W. The adhesive layer 2a of the band-shaped cushioning material 2 can be brought into close contact with the work W when the tool 1 is advanced to the mounting portion 4. In addition, an intake hole 11 for adsorbing the band-shaped cushioning material 2 is formed in the groove bottom portion 10, and the peripheral edge portion 12 protrudes from the groove bottom portion 10 so that the suction hole 11 is pressed against the band-shaped cushioning material 2 and closely adhered thereto. Is formed.

The side wall 9a surrounding the buffer material holding groove 9 is
The inner surface thereof is formed in an outward tapered surface 9b so that a positioning error of the cushioning material 2 of the cushioning material supply device 5 can be allowed. When the mounting portion 4 is a flat surface, the surface of the suction conveyor 5a is also formed to be flat, and the holding groove 9 is also formed to overlap each of these flat surfaces. When the mounting portion 4 is a curved surface, the surface of the suction conveyor 5a is also formed. The holding groove 9 is formed to have the same curved surface as that of the mounting portion 4, and the holding groove 9 is also formed to have a shape overlapping with these curved surfaces. Therefore, the holding groove 9 exactly overlaps the surface of the suction conveyor 5a and the surface of the mounting portion 4, so that the buffer material 2 can be surely sucked and the buffer material 2 can be closely attached to the mounting portion 4.

A vacuum pump (suction device) 13 for adsorbing the band-shaped cushioning material 2 is connected to each of the suction holes 11, and detects that the holder 1 has been dropped onto the cushioning material supply device 5. The vacuum pump 13 is turned on on the basis of an output signal from the position sensor 14 to be turned on, and the vacuum pump 13 is turned on based on the output signal of the position sensor 15 for detecting that the holder 1 has been dropped onto the buffer material mounting portion 4. Is turned off.

Therefore, when the holding tool 1 is retracted from the work W and is lowered from the buffer material supply device 5, suction starts, and the band-shaped buffer material 2 is attracted to the holding groove 9, and the buffer material 2 is sucked.
When the holding tool 1 is lowered onto the cushioning material attaching portion 4 and the cushioning material 2 adheres to the work W, the suction is stopped, and the cushioning material 2 is It is attached to the mounting portion 4 and can be easily removed from the holder 1.

The above is an example of the configuration of the present invention, and its operation will be described below. First, when the work W is positioned at a predetermined position by the conveyor 3, the holder 1 is lowered onto the belt-shaped buffer supply device 5 by the reciprocating device 7 and the cylinder 8, and the buffer 2 is fitted into the groove 9. At the same time, the vacuum pump 13 is turned on, and air is sucked from each air inlet 11. At this time, since the peripheral portion 12 of the intake hole 11 is pressed against the cushioning material 2 and is closely attached to the cushioning material 2 in a state where the cushioning material 2 is depressed, there is no gap between the suction hole 11 and the cushioning material 2. The material 2 can be adsorbed. In addition, since the inner surface of the side wall 9a of the holding groove 9 is formed in the tapered surface 9b which is opened outward, even if the cushioning material 2 and the holder 1 of the cushioning material supply device 5 are slightly misaligned, they are not positioned. Errors can be tolerated.

Next, the cylinder 8 is contracted to hold the holder 1.
Is lifted, the release paper 2b is adsorbed on the suction conveyor 5a, so that the buffer material 2 is peeled off from the release paper 2b and held by the holder 1, and the holder 1 is moved by the reciprocating device 7 to the buffer material of the work W. Move to the mounting part 4 and move the cylinder 8
Is extended, the holder 1 is lowered to a position where the holder 1 overlaps the mounting portion 4.

At this time, since the holding groove 9 is formed in a shape corresponding to the mounting portion 4, the adhesive layer 2a of the cushioning material 2 can be accurately bonded to the mounting portion 4. Further, since the holding groove 9 is formed shallower than the thickness of the cushioning material 2, the adhesive layer 2
a is exposed to the outside of the groove 9, and the adhesive layer 2 a is tightly adhered to the mounting portion 4, so that the adhesive layer 2 a is securely adhered.

When the cylinder 8 is extended and the holder 1 is lowered to a position overlapping with the mounting portion 4, a detection signal is output from the position sensor 15 and the vacuum pump 13 is turned off. At this time, the cushioning material 2 is adhered to the mounting portion 4,
Since the intake from the intake hole 11 is stopped, when the cylinder 8 is thereafter contracted, the cushioning material 2 easily comes off from the holding groove 9 and only the holder 1 is lifted. And the holder 1
Is returned to the buffer supply device 5 by the positioning device 6, and when the next work W is positioned at the predetermined position, the above operation is repeated.

In the description of the embodiment, the case where the band-shaped cushioning member 2 is attached as the door sealing member is described. However, the present invention is not limited to this, and the case where the band-shaped cushioning member 2 is attached as the packing of the lid of the container. The use of the band-shaped cushioning material 2 is optional. The suction device is not limited to one that starts and stops suction by turning on and off the vacuum pump 13. The suction pump is turned on, and each suction hole 11 is connected to the vacuum pump by switching a valve. It may be made open to the atmosphere, or the suction action of the ejector may be used.

Further, the shock absorber 2 is supplied by the shock absorber supply device 5.
Is not limited to the case in which the buffer material 2 is automatically supplied, and the case where the worker sets the cushioning material 2 in the groove 9 when the holder 1 is retracted. In this case, if a large number of intake holes 11 are provided, it becomes difficult to adsorb the cushioning material 2. Therefore, the intake holes 11 are arranged at both ends along the longitudinal direction of the holding groove 9 so that the cushioning material 2 can be set with both hands. It is preferable to form the openings one by one. However, if a separate vacuum pump is connected to each intake hole 11, the cushioning material 2 can be securely brought into close contact with each intake hole 11.

[0019]

As described above, according to the present invention, the band-shaped cushioning material can be reliably sucked and held, and the holding tool is formed in a shape corresponding to the mounting portion. This has an excellent effect that the cushioning material can be securely positioned without being displaced by being securely positioned at the mounting portion.
