Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for applying filler to automobile reinforcements.

Generally, in car body reinforcement structures such as car roofs, bonnets, and trunk lids, a gap filler called mastink sealer is usually applied to the top surface of the reinforcement in order to provide tension and rigidity to the outer skin of the car body. The reinforcement is bonded to the inside of the outer panel with a gap filler interposed between the reinforcement and the outer panel.

By the way, conventionally, as an apparatus for applying a filler to such reinforcement, a wiper is first moved along the longitudinal direction of the reinforcement to clean the upper surface of the reinforcement, and then one or one group of fillers is cleaned. It is known that a filler application nozzle is moved along the longitudinal direction of the reinforcement to apply the filler to a predetermined location on the reinforcement.

However, in the conventional apparatus described above, one or one group of coating nozzles and wipers are moved with a stroke approximately corresponding to the length of the reinforcement in the longitudinal direction, so the filler coating process takes a long time. there were.

The present invention has been made in this respect, and a pair of filler application nozzles and a wiper are placed opposite each other by sandwiching the reinforcement on the outside in the longitudinal direction of the reinforcement, and each pair can be moved toward and away from each other. By moving the application nozzle, the stroke is approximately 1/2 of the span of both coating nozzles, that is, approximately 1 of the longitudinal length of the reinforcement.
To provide a filler applicator for automobile reinforcements, which can apply filler to the reinforcement and clean it with a stroke of /2, thereby shortening the filler application process time. It is something to do.

That is, the present invention includes a transfer device that sequentially and intermittently feeds reinforcements in a side-by-side state, and an endless chain belt that is disposed on the upper blade of the transfer device and that moves in the longitudinal direction of the reinforcement and rotates in the vertical direction. , filler application nozzles attached to the upper and lower chains of the endless chain belt and on both sides of the reinforcement in the longitudinal direction, and a filler application nozzle installed on the upper and lower chains of the endless chain belt, respectively, and a filler application nozzle attached to the reinforcement immediately before the application process by the application nozzle. Wipers are placed on both sides of the reinforcement in the longitudinal direction to clean the upper surface, and are attached to the upper and lower chains of the endless chain belt, respectively, and the endless chain belt is connected to both coating nozzle pans. The invention is characterized in that it consists of a cylinder that reciprocates with a stroke of approximately 1/2 of the stroke, and that the application nozzle and the wiper can be moved toward and away from each other by the cylinder.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

In Figures 1 and 2, 1 indicates reinforcement members (to which filler is to be applied) W arranged side by side (i.e., the longitudinal direction of the reinforcements W is lined up and perpendicular to the transport direction, and they are arranged at regular intervals. 2 is a gate-shaped base frame installed across the conveyor 1, and 3 is an endless chain belt tear placed above the conveyor 1. The reinforcement W consists of sprocket wheels 4, 4 rotatably supported on the left and right upper portions of the base frame 2, and a chain 5 wound around both sprocket wheels 4. That is, it extends in a direction perpendicular to the direction of transport force X) and is provided so as to accompany the upper and lower lines.

Further, reference numeral 6 denotes a pair of parallel guide bars that are horizontally suspended on the base frame 2, and gate-shaped slide frames γa and 7b are provided on the left and right sides of the guide bars 6, respectively, so as to extend the longitudinal direction of the reinforcement W. The left slide frame γa is located on the outside of the direction and is slidably supported in a hanging manner facing each other. The right slide frame γb is attached to the upper chain 5 of the chain belt 3 at its upper rear end.

On both legs of each of the slide frames γat7b, l pairs of levers 8at8at8b, 8b are swingably supported at their central portions, and between the lower ends of the levers 8a, 8a and 8bt8b, respectively. Two filler application nozzles 9a and 9b are fixedly supported in parallel, and
Wipers 11a and 11b are attached to levers 8a and 8b on the front side (left side in FIG. 2) with respect to the transfer direction Provided to be cleaned.

Additionally, O-ra 12a, 12b are rotatably supported between the upper ends of the levers 8a, 8a and 8bt8b. The rollers 12a and 12b are slidably fitted into guide grooves 14 formed in accordance with the top surface shape of the reinforcement W, and when the rollers 12a and 12b slide within the guide grooves 14, the levers 8a and 8b are fitted into the guide grooves. 14, that is, following the upper surface shape of the reinforcement W, the application nozzles 9a, 9b and wipers 11a, 11
b is also configured to move following the shape of the upper surface of the reinforcement W.

Furthermore, 15 is a cylinder fixed horizontally near the upper side of the base frame 2, and the tip of the piston rod 16 of the cylinder 15 is connected to the right slide frame γb,
Further, the cylinder 15 has a stroke of approximately 1/2 of the span between both application nozzles 9at9b (that is, approximately 1/2 of the length in the longitudinal direction of the reinforcement W), and the cylinder 15 has a stroke of approximately 1/2 of the span between the two coating nozzles 9at9b (that is, approximately 1/2 of the length in the longitudinal direction of the reinforcement W). (b) When operating, the chain belt 3 is reciprocated via the right slide frame γb, thereby causing the left and right application nozzles 9a.

The wipers 9b and wipers 11a and 11b are configured to move toward and away from each other.

Next, to explain its operation, when the reinforcement member (W) that has been intermittently fed by the conveyor 1 stops intermittently at a position below the wipers 11a and 11b immediately before the coating process, first, the cylinder 15 is connected to both coating nozzles 9a. , 9b is retracted with a stroke of approximately 1/2 of the span of 9b, and then extended (one reciprocating operation), so that the right slide frame γb moves along the guide rod 6 with the same stroke as the cylinder 15. Along with this, the chain belt 3 also reciprocates with the same stroke.

That is, the upper chain 5 of the chain belt 3 moves to the left and then to the right, and the lower chain 5 moves to the right and then moves to the left, so that the left slide frame γa also moves along the guide rod 6 into the cylinder. It will reciprocate with the same stroke as 15.

Therefore, the levers 8a, 8 are attached to both the slide frames 7atγb.
The wipers 11a and 11b (and the application nozzle 9at9b) supported through the cylinder 15 also reciprocate with the same stroke as the cylinder 15, and after moving to the right side, the left wiper 11a moves to the middle of the span between both application nozzles 9a and 9b. The right wiper 11b reverses at a point (that is, the midpoint of the longitudinal length of the reinforcement W) and moves to the left, and the right wiper 11b moves to the left, then reverses at the midpoint of the reinforcement and moves to the right. Both wipers 11a
, 11b move toward and away from each other in the longitudinal direction of the reinforcement member W, so that the upper surface of the reinforcement W can be cleaned in half the time required in the conventional method.

Moreover, the wipers 11a and llb are rollers 12a,
Since the lever 8at 8b is attached to the lever 8at 8b which moves to follow the top surface shape of the reinforcement W by sliding in the guide groove 14 of the reinforcement W, the top surface of the reinforcement W can be cleaned more effectively.

Next, when the reinforcement W after the cleaning process is further transferred and stops intermittently at a position below the coating nozzles 9a, 9a, the cylinder 15 is operated back and forth once, and the coating nozzle is moved in the same way as in the cleaning process described above. 9a, 9b (and wipers 11a, 11b) are reinforcement W
By moving the filler toward and away from the reinforcement W in the longitudinal force direction with a stroke of approximately 1/2 of the longitudinal length, the filler can be placed at a predetermined location on the reinforcement W in 1/2 of the time required by conventional methods. a will be applied.

Moreover, as above, the coating nozzle 9a. 9b moves according to the top shape of the reinforcement W,
The filler can be applied accurately.

As explained above, according to the present invention, l pairs of filler application nozzles and wipers are arranged to sandwich the reinforcement on the outside in the longitudinal direction of the reinforcement, and each pair is moved toward and away from each other. By doing so, the cleaning of the reinforcement and the application of the filler can be carried out in approximately 1/2 the time compared to the conventional method, so that the time required for the filler application process can be significantly shortened.

In addition, if the coating nozzle and wiper are made to move following the top surface shape of the reinforcement, the cleaning and filler coating can be performed reliably and well, which is an advantage.
