[Prior Art] In general, decorative members are stuck on the front and back surfaces of a panel member so as to make the surface smooth or to enhance the appearance by decoration. On the other hand, a tape member is crimped to a side portion of the panel member, that is, a cut-off end portion, so as to increase the beauty of the side surface of the panel member and ensure durability. In this case, the pressing of the tape member to the side surface of the panel member often depends on manual labor. However, the economic cost has increased, and the production efficiency has not been significantly improved.

Therefore, as disclosed in, for example, Japanese Patent Application Laid-Open No. 1-95002, an edge banding machine for automatically pressing a tape member to a side portion of a panel member has been proposed as a new technical idea. However, according to the technology disclosed in Japanese Patent Application Laid-Open No. 1-95002, it is possible to attach a tape member to a flat side surface shape. Cannot be fully supported. That is, according to the edge banding machine disclosed in Japanese Patent Application Laid-Open No. 1-95002, since the edge banding head has an extremely large configuration, the side surface of the panel member is extremely curved and concave. In such a case, it is difficult to displace the pressing roller itself along the shape thereof, and the attachment of the panel member having such a shape must rely on manual labor. In other words, a device for automatically attaching a tape member to a side surface of a panel member for a complicated shape has not been proposed so far.

[Problems to be Solved by the Invention] The present invention has been made to overcome the above-mentioned disadvantages, and even when the side surface of the panel member is complicatedly curved or bent, the tape member pressing means is provided. Is displaced along the shape of the panel member, and the pressing member is displaced from a direction perpendicular to the side surface of the panel member to press the tape member against each other, thereby applying a sufficient force to the panel member and the tape member. Then, this does not cause the tape member to be easily peeled off, and has an excellent aesthetic feeling.
It is an object of the present invention to provide an economical edge member crimping device that does not require any manual operation.

[Means for Solving the Problems] In order to achieve the above object, the present invention is an apparatus for crimping a tape member into a concave portion of a flat panel member, the apparatus comprising: an X direction; And a pressing roller for pressing the tape member against a side surface defining a concave portion of the panel member; and the press. Actuator for displacing the pressing roller from a direction substantially perpendicular to the side surface of the recess, a block body for supporting the pressing roller and the actuator, and the block body can be displaced to a desired angle. And a rotary drive source.

[Operation] According to the present invention, a tape member is arranged on, for example, a curved concave side surface of a flat panel member, and a pressing roller is placed on the side surface of the tape member under the urging action of a rotation drive source. Press from a direction perpendicular to the direction. Thereby, a sufficient pressing force can be obtained, the tape member can be securely pressed against the side surface of the concave portion, and the actuator for displacing the pressing roller is rotated so that the actuator is in a direction perpendicular to the side surface of the tape member. Since the displacement is performed via the drive source, the tape member can be pressed against the concave portion having a complicated shape of the panel member.

Further, in the figure, reference numeral 226 is a roll tape base fixed to the support 26, and the roller 230 is fixed to the tip of an elastic body 228 extending in the radial direction from the center axis thereof.
While applying tension by the roller 230, the edge material tape 232 is fed to the feed roller 98 in a state where the tape is twisted by 90 ° by the roller member.

The edge member crimping device according to the present invention is basically configured as described above. Next, the operation and effects thereof will be described.

First, basically, the edge member crimping device according to the present invention is NC
The operation is performed under the control of. That is, the crimping mechanism 12 and the trimming mechanism 14 are configured to perform their operations according to the NC information from the controller unit 16. Therefore, first, the panel members W1 and W2 are already mounted on the suction box groups 24a and 24b, and the work is sufficiently positioned by the suction function. As can be easily understood from the drawings, the panel members W1 and W2 in this case have a concave portion that curves largely inward. Therefore, based on the NC information from the NC controller 16, the crimping mechanism 12 and the trimming mechanism 14 are first displaced together with the support 26 and positioned at a predetermined position. Next, the edge material tape 232 wound around the roll tape table 226 and given a predetermined tension by the elastic body 228 is manually passed to the edge material guide roller 100, and from the edge material guide roller 100, Further, it is inserted between a glue pressing roller 88 and a gluing roller 86 via a cutter including an edge material feed roller 98, a fixed blade 92, and a movable blade 94, and further wound around an edge material press roller 82. Next, the pressure bonding mechanism 12 is energized. That is, the holding unit 34 is displaced in the arrow Y direction by rotating the ball screw 42 under the action of the servomotor 40. When the predetermined position is reached, the press shaft elevating cylinder 60 is then urged. The driving action of the press shaft elevating cylinder 60 displaces the cylinder rod 62 and the plate 56 along the rail members 50a and 50b. By lowering the pressure bonding mechanism 12 in this manner, the edge material press roller 82 faces the side surface of the panel member W2. Then, when the rotary drive source 80 is driven to rotate, the rotational force of the rotary drive source 80 is transmitted to the edge material feed roller 98 and the gluing roller 86 via the chain 87. Accordingly, the edge material tape 232 is fed to the side surface of the panel member W2 with a predetermined tension, and the glue from the glue tank 90 is supplied to the glue roller 86 over the entire surface. . On the other hand, the press pressure air cylinder 74 is energized. The urging action of the air cylinder 74 displaces the support block 78 toward the panel member W2, and presses the edge material press roller 82 via the edge material tape 232 against the side surface of the panel member W2. At this time, the θ-axis rotation motor 97 is urged against the panel member W2 so as to press the support block 78 from a direction whose longitudinal direction is orthogonal to the side surface of the panel member W2. Of course, the position information at this time is sent from the NC controller unit 16.
Therefore, even if there is a concave portion that is curved in the panel member W2,
The edge material press roller 82 can be pressed into contact (see FIG. 10).
For this purpose, any form of edging tape 23
The action of pressing 2 is not hindered. In this way, the edge material tape 232 is moved to the panel member W2 based on the NC information.
When the side surface is substantially rotated, the edge material cutter air cylinder 96 is urged. As a result, the movable blade 94 is displaced toward the fixed blade 92, and cuts the edge material tape 232. In this way, when the circling of the edge material and the pressing process are completed, the air cylinder 74
Is driven again, the cylinder rod 76 performs a retreat operation,
The support block 78 is raised. Here, the basic edge material pressing step is completed.

Next, the trimming mechanism 14 is energized. As described above, the trimming mechanism 14 operates based on the same NC information as the crimping mechanism 12.

Therefore, the cylinder 64 is biased to
And the positioning of the trimming mechanism 14 as a whole is performed. Next, the air cylinder 206 is urged, and the lowering operation of the cylinder rod 208 causes the end cutter blade 212 to face the front end of the edge member pressed against the panel member W2. Thereafter, the end cutter high-frequency motor 210 is energized, and the end cutter blade 212 rotates at a high speed to cut the end of the edge material tape 232.

In this way, after one end of the edge material tape 232 is cut under the action of high speed rotation, the air cylinder 206 is urged again to raise the cylinder rod 208, and the end cutter blade 212 Return to position.

Next, a trimming cutter 17 is provided on the side surface of the panel member W2.
Bring 2,174. At this time, the separation distance between the trimming cutters 172 and 174 is adjusted according to the thickness of the panel member W2 under the urging action of the air cylinders 222 and 224. The trimming high-frequency motor 162 is energized, and the trimming cutters 172, 174 are driven to rotate to rotate the panel-side rollers 176,
Excess portions of the edge material tape 232 projecting from the upper surface and the lower surface of the panel member W2 under the rotation guiding action of the panel upper and lower rollers 178 and 180 are removed. At this time, the air cylinder 156 is always in an energized state, and operates so as to press the trimming cutters 172, 174 under the displacement action of the support block 160.

Next, the air cylinder 184 is urged, and the other end cutter blade 202 is positioned at a predetermined position as the cylinder rod 196 descends. Then, by energizing the high frequency motor 200 for the end cutter,
Will be cut off.

After a series of operations are completed, the cylinder 184
Is energized, and the end cutter high-frequency motor 200 and the end cutter blade 202 return to their original positions.

According to this embodiment, as described above, even when the panel member W2 has an extremely complicated concave shape, the panel member W2 is displaced in accordance with the shape, and further, the support block 78 is configured to support the edge material press roller 82. The pressing is performed from the surface of the edge material tape 232, that is, the direction perpendicular to the side surface of the panel member W. Therefore, the pressing force is extremely strong, and the biasing force of the air cylinder 74 can be controlled in accordance with the shape, so that an optimum pressing force can be provided.

Moreover, since the shape near the edge material press roller 82 is extremely simplified, the edge material press roller 82 can enter even in a small space, and therefore,
Conventionally, even a curved shape that had to be relied on manually can be easily processed. Furthermore, by using the NC control, the crimping mechanism 12 and the trimming mechanism 14 can be operated on the same path, so that there is an advantage that the control itself is simplified.

[Effects of the Invention] As described above, according to the present invention, even when the workpiece has an extremely complicated curved shape and the shape is greatly curved inward from the side surface of the work, the edge material press is performed. The roller can be suitably pressed against the side surface of the work. Therefore, an effect is obtained in which the edge material can be pressed against the side surface of the work with an optimum pressure. Moreover,
Since the pressing operation of the edge material can be quickly performed without requiring a skilled labor, the production efficiency is extremely increased and the effect of being economical is obtained.
