[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weather strip assembling apparatus for mounting a weather strip on a flange of an opening of a vehicle body conveyed by a conveyor in synchronization with the vehicle body.

[0002]

2. Description of the Related Art As a conventional weatherstrip assembling apparatus, as described in Japanese Utility Model Laid-Open Publication No. 2-143166, a weatherstrip is inserted into a fitting groove provided in a jig frame along an inner peripheral shape of a vehicle body opening. There is known an apparatus in which a weather strip is loaded and extruded by an extrusion roller that rolls around the outer periphery of a jig frame, so that the weather strip is assembled to a flange of an opening.

[0003]

In a conventional weatherstrip assembling apparatus, since the weatherstrip is pushed into the flange by an extrusion roller, especially in the case of an annular weatherstrip, immediately before the end of the assembling operation. In such a case, a surplus occurs in the weather strip. Therefore, there was a problem that it was difficult to assemble the weather strip evenly over the entire flange of the opening.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to uniformly assemble a weather strip with a flange formed in an opening of a vehicle body. It is an object of the present invention to provide a weather strip assembling apparatus which can be attached.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a weather strip assembling apparatus for mounting a weather strip on a flange of a vehicle body opening, wherein the weather strip is held opposite to the flange and the weather strip is held. A plurality of rubber pushers to be pushed into the flange, a chain stretched and driven along the flange, and an attachment for pushing the vicinity of the weather strip pushed into the flange by the rubber pusher while traveling by the chain into the flange. The means is provided on a carriage via a plate, and the carriage is provided with a slide means for adjusting the position of the plate and a synchronization means for synchronizing with the vehicle body.

[0006] The attachment means may be a vibrating mechanism for driving the weather strip into the flange by vibration.

[0007]

The carriage is synchronized with the vehicle body by the synchronization means, and the position of the plate is adjusted with respect to the opening by the slide means.
When the plurality of rubber pushers holding the weather strip sequentially push the weather strip into the flange, the mounting means running by the chain pushes the vicinity of the weather strip pushed into the flange by the rubber pusher into the flange.

Further, the weather strip can be attached to the flange by means of vibration.

Between the guide rails 13 laid on the chain 6 and the support members 41
Are connected.

The vibrating tool 40 vibrates a rod 44 having a pushing roller 43 rotatably mounted at a tip thereof in a direction of an arrow A perpendicular to the flange 16a. By exchanging the lever 45 with two notches 45a and 45b, the amount of protrusion of the rod 44 can be switched between two stages. Reference numeral 46 denotes a free bearing attached to the support member 41.

As shown in FIGS. 6 and 7, the synchronizing means 10 includes a positioning pin 50a fixed to the tip of the two guide rods 50, a positioning hole 16b formed below the opening 16, and FIG. As shown in the figure, the carriage 24 includes a bogie fixing cylinder 51 fixed to a lower portion of the frame 24.

The guide rod 50 is attached via a plate 54 to a rod 53a of a positioning cylinder 53 fixed on an upper part of a bracket 52 fixed on the upper surface of the base 20. The positioning pin 50a is disposed so as to face a positioning hole 16b formed below the opening 16 downward.

As shown in FIG. 2, the bogie fixing cylinder 51 is disposed so that the rod 51a faces upward and faces the bottom surface 9a of the vehicle body 9.
A plate 55 which is in contact with the bottom surface 9a of the vehicle body 9 is attached to the tip of the.

The operation of the weather strip assembling apparatus 1 configured as described above will be described. First, the annular weather strip W is attached to the holding portion 32 of the rubber pusher 4 of the weather strip assembling apparatus 1 waiting on the line side.
Is set. At this time, the retracting cylinder 30, the pressing cylinder 31, the bogie fixing cylinder 51, and the positioning cylinder 53 are each in a retracted state. The vibration mechanism 7 has the lever 45 engaged with the notch 45a, and the pushing roller 43 is retracted as shown in FIGS.

Next, the weatherstrip assembling apparatus 1 is fixed to the opening 16 of the vehicle body 9 and is moved to the line side to synchronize with the vehicle body 9. Further, the bogie 2 is adjusted in accordance with the speed of the vehicle body 9 to be conveyed so that the positioning pins 50a face the positioning holes 16b formed below the opening 16.
To move.

When the positioning cylinder 53 is moved forward,
The positioning pins 50a are fitted into the positioning holes 16b.
At the same time, the carriage fixing cylinder 51 is moved forward to press the plate 55 against the bottom surface 9a of the vehicle body 9. Then, the frame 24 is lowered by a predetermined dimension against the elastic force of the spring 25 due to the reaction, the plate 3 is brought into close contact with the opening 16 and positioned in the height direction, and the weather strip assembling apparatus 1 is attached to the vehicle body 9. Fixed.

The position of the plate 3 is adjusted in the traveling direction of the vehicle body 9 by the sliding means 8 comprising six guide members 26 and three rails 27, and the plate 3 is positioned in the traveling direction of the vehicle body 9.

Next, when the position of the vibration mechanism 7 shown in FIG. 1 is set as the original position, and the vibration mechanism 7 travels in the direction of arrow B by driving the chain 6, as shown in FIG.
Only the rubber pusher 4 approaching first moves the pressing cylinder 31 forward. Accordingly, the other rubber pusher 4 is in a state of holding the weather strip W while the pressing cylinder 31 is in the retracted state.

Then, the weather strip W is pushed into the opposed flange 16a by the holding portion 32. Furthermore,
After the lever 45 is engaged with the notch portion 45b and the pushing roller 43 is protruded as shown in FIG.
While traveling along the guide rail 13 in the direction of arrow B, the pushing roller 43 of the vibrating tool 40 starts vibrating in the direction of arrow A.

Due to the vibration of the pushing roller 43, the vicinity of the weather strip W at the portion pushed by the holding portion 32 is assembled so as to be beaten into the flange 16a.

When the running vibration mechanism 7 approaches the rubber pusher 4 pressing the weather strip W, the rubber pusher 4 causes the pressing cylinder 31 to move backward so as not to hinder the running of the vibration mechanism 7 and then retracts. Cylinder 3
3, the pressing cylinder 31 is rotated upward about the other end 33b of the connecting member 33 having a fixed rear end, as shown in FIG.

Then, only the rubber pusher 4 to which the vibration mechanism 7 comes closer causes the pressing cylinder 31 to move forward. Therefore, the other rubber pushers 4 except the rubber pusher 4 that is operated first are in a state of holding the weather strip W while the pressing cylinder 31 is in the retracted state.

Then, the weather strip W is pushed into the opposed flange 16a by the holding portion 32. Furthermore,
The vicinity of the weather strip W at the portion pressed by the holding portion 32 due to the vibration of the pressing roller 43 is the flange 1.
6a.

In the same manner, the weather strip W is entirely assembled into the flange 16a formed in the opening 16 by the action of the rubber pusher 4 and the vibration mechanism 7. The vibration mechanism 7 returns to the position (original position) of the vibration mechanism 7 shown in FIG. 1 again. Then, the bogie fixing cylinder 51 and the positioning cylinder 53 are moved backward, and the weatherstrip assembling apparatus 1 is separated from the vehicle body 9.
Returning to the line side, one cycle of the work of assembling the weather strip W is completed.

[0032]

As described above, according to the present invention, the annular weather strip can be evenly and uniformly assembled to the flange by the cooperative operation of the rubber pusher and the mounting means.

Further, by using a vibration mechanism as the mounting means, the weather strip can be evenly and surely mounted on the flange without being left behind.
