[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a rod-like body inserting machine (hereinafter, referred to as "inserting machine") into a long tube of the present invention will be described in detail. 1 to 13 show an embodiment of the insertion machine of the present invention. FIG. 1 is a front view showing a main part of the insertion machine, FIG. 2 is a plan view of FIG. 1, and FIG. FIG. 4 is a side view of the main part around the wire actuator, FIG. 5 is a cross-sectional view around the ejector, FIG. 6 is a partial cross-sectional view around the stopper, and FIGS. It is explanatory sectional drawing showing the insertion process of a rod-shaped body. This is applied to a case in which a sponge-like rod-like body (commonly called latex) is inserted into a long rubber tube of a front door opening trim.

The insertion machine includes a mounting table 1, an ejector 2, a wire 3, a stopper 4, a wire operating device 5, a protective tube 6, a position sensor 7, and a hole punch 8. The insertion machine of the present embodiment has two rows of facilities for inserting the rod-shaped body B into the long tube T (FIG. 2). The mounting table 1 has a plate 12 on which an elongated tube T is mounted on an upper surface of a frame 11. The plate 12 is provided with angles 13, 13 for guiding both sides of the long tube T so that the long tube T can be easily set (FIG. 6). Further, in order to stably hold the set long tube T, the band plate 1 is used.
4 is assigned. In FIG. 1, the illustration of the angle 13 and the band plate 14 is omitted. Reference numerals 15 and 16 denote an opening of the stopper 4 and an opening of the hole punch 8 provided on the mounting table 1. At the stopper opening 15, the angle 13 and the band plate 14 are divided so that the stopper 4 can operate.

The ejector 2 is a suction tool attached to one end of the plate 12 via a support piece 17.
By pointing the outlet nozzle 21 toward the plate 12 and inserting the mouth of the long tube T into the outlet nozzle 21, the long tube T is guided by the angles 13 and the band plate 14 and is set correctly on the plate 12. (FIG. 6). Code 22
Indicates a high pressure air blowing nozzle. When high-pressure air is sent from the blowing nozzle 22, the rod-shaped body B is sucked together with the air at the suction port 23 as shown in FIG. In this embodiment, a breath rider manufactured by Breath Corporation is used as the ejector 2. The ejector 2 can be operated and sucked by a power switch of an operation plate, and also can be sucked by a manual pedal.

The wire 3 is a plastic wire having a clip 31 which can be inserted into the ejector 2 at one end, and a metal element 33 is attached to the other end here. The metal element 33 responds to the proximity switch 7 described below,
It is useful for positioning the rod B. The plastic wire 32 is made of resin so as not to react with the proximity switch 7. Of course, if a position sensor other than the proximity switch 7 is used, the position sensor is not limited to the plastic wire 32. The wire 3 is disposed in a U-shaped body that is folded back through the wire actuator 5 as shown in FIG. 3 so that the clip 31 faces the suction port 23 (entrance) of the ejector 2. This is because the entire insertion machine is not lengthened. The plastic wire 32 at the bottom of the U-shaped body is housed in the protective tube 6, and
The plastic wire 32 in the bent portion is housed in the flexible tube 9 to ensure safety. The clip 31 is normally in a state of protruding through a nozzle 52 provided on a frame 51 for a wire operating device (FIG. 3). The clip 31 of the present embodiment is a clip-type stopper.

The stopper 4 includes an air cylinder 41 and a locking plate 42 attached to the air cylinder 41. The locking plate 42 allows the upper end thereof to be seen on the plate 12 from the opening 15 (FIG. 6). The locking plate 42 is movable forward and backward by the operation of the air cylinder 41 so that the hook-like head 43 at the upper end can press the long tube T set on the plate 12 (see FIG. 6). Broken line). When the hook-shaped head 43 is pressed from the outside of the long tube T, the rod-shaped body B inserted into the long tube T and disposed at a predetermined position is locked.
The rod B is set at a predetermined position in the long tube T by clamping the rear end of the rod B to the clip 31 (described later). When the wire 3 is pulled by the wire operating device 5 in the stopped state, the pulling force exceeds the pinching force of the clip 31, and the clip 31 comes off while sliding on the rod B. Wire 3
, The rod B is kept locked by the pressing of the locking plate 42.

The wire operating device 5 is capable of feeding the wire 3 in contact with a plastic wire portion extending from the wire end to which the clip 31 is attached to the flexible tube 9 at the bend. The plastic wire 32 in this portion is not covered with the protective tube 6 or the flexible tube 9 and is exposed, and the plastic wire 32 is stored in the groove of the disk 53 (FIG. 4). Disk 53
A pulley 532 is attached to one end of a shaft 531 of the motor 54, and a timing belt 55 is hung on the pulley 532 and a pulley 542 fixed to a rotation shaft 541 of the motor 54.
The disk 53 can be rotated by the rotation of. Clip 3
The wire 3 having stopped the rod-shaped body B in 1 is sucked into the long tube along with the rod-shaped body B by suction of the ejector. However, the wire 3 is fed by the rotation of the motor 54 to assist suction of the ejector. I have. The wire operating device 5 has a structure in which the wire 3 sent into the long tube by the reverse rotation of the motor 54 can be pulled back. Reference numeral 56 denotes an auxiliary disk.
The lower end of the rod of the air cylinder 57 is fixed to the rotation shaft 561 of the auxiliary disk 56. When the air cylinder 57 operates, the rod 571 extends, and the auxiliary disk 56 descends, and enters the groove of the disk 53. When the motor 54 rotates, the auxiliary disk 56 comes into contact with the wire 3 and plays a role of smoothly feeding the wire 3 by the disk 53.

The protection tube 6 is a pipe for accommodating a lower portion of the wire 3 folded in a U-shape. A proximity switch 7 serving as a position sensor is attached to the protection tube 6 at a predetermined position.
In FIG. 1, the protection tube 6 and the proximity switch 7 are fixed to a frame 11 (not shown). The proximity switch 7 has a role of arranging the rod B at a predetermined position in the long tube T with the metal element 33 attached to the wire 3. The rod-shaped body B is sucked into the long tube T with the clip 31 clamped at the rear end thereof.
Approaching within a certain distance of the proximity switch 7,
The proximity switch 7 outputs an output signal.
Then, by stopping the wire actuator 5 and stopping the movement of the wire 3, the rod-shaped body B is kept at a predetermined position in the long tube T even if the ejector suction is continued.

The hole punch 8 has a pin 82 attached to a rod of an air cylinder 81 fixed to the plate 12. The operation of the air cylinder 81 raises the pin 82,
A drain hole K can be opened in the long tube T through the opening 16 (FIG. 13B). Here, two drilling tools 8 are provided in each row in order to provide two water draining holes K at the front and rear of the long tube T.

The operation panel is located above the wire actuator 5 (not shown). When the start switch on the operation panel is turned on,
The wire 3 is sent out by the wire operating device 5 together with the suction of the ejector, and then the wire operating device 5 and the ejector 2 stop when the proximity switch 7 operates. Then
The stopper 4 is moved forward, and the long tube T is pressed to push down the rod B in the long tube. Subsequently, the wire 3 is pulled back by the reverse rotation of the motor 54 according to the wire operating device 5. By this retraction, the clip 31 comes off the rod-shaped body B, and the wire 3 returns to the original position. Then, the stopper 4 retreats and the rod-shaped body B is disposed at a predetermined position in the long tube, and the stopper 4 and the wire 3 take a next standby state. This is a configuration that is performed by sequence control incorporated in the panel.

Next, using the above insertion machine, a long tube T
The operation of the insertion machine will also be described while describing a method of inserting the rod-shaped body B into the body. First, a long tube T and a rod-shaped body B to be inserted therein are prepared (FIG. 13A). Then, the mouth of the long tube T is inserted into the outlet nozzle 21 of the ejector 2 and the plate 12 surrounded by the angle 13 and the band plate 14 is inserted.
The long tube T is set on the upper side (FIGS. 2 and 6). Next, the ejector 2 is operated with a manual pedal (not shown),
The tip of the rod B is sucked into the long tube (FIG. 7). Then, the clip 31 is clamped to the rear part of the rod B (FIG. 8). At this time, most of the rods B are inserted into the long tube, and the clip 31 makes it easier to stop the rear part of the rods. Further, at this time, since the auxiliary disk 56 is at a position floating from the disk 53 (FIG. 4), the wire 3
The clip 31 can be easily pinched to the rod-shaped body B without difficulty.

Thereafter, the start switch of the operation panel is turned on. Then, together with the ejector suction, the wire actuator 5
Works, and the wire 3 with the rod B is inserted into the long tube T.
Is sent smoothly. The wire actuator 5 includes a motor 5
The rotation of the disk 4 rotates the disk 53 and sends out the wire 3. At this time, the rod of the air cylinder 41 descends and the auxiliary disk 56 enters the groove of the disk 53 to prevent the wire 3 from running idle. . The rod B is sucked into the long tube while dragging the wire 3. Thus, the rod-shaped body B approaches a predetermined position of the long tube T. Then, since the wire 3 is also sent together, the metal element 3
3 approaches the proximity switch 7. Then, the rod-shaped body B is moved a predetermined distance L ₁ from the end of the long tube T.
Is reached, the proximity switch 7 operates to stop the wire actuator 5, and the rod-shaped body B is positioned at a predetermined position of the long tube T.
Is set (FIG. 9). Ejector 2 stops almost simultaneously with the stop of wire actuator 5.

Subsequently, the stopper 4 is actuated, and the hook-shaped head 43 presses the long tube T to push the rod B in the long tube.
Is locked (FIG. 10). Although not shown in FIG. 10,
When the hook 43 presses the long tube T, the angle 1
3 receives the pressing of the stopper 4, the rod-shaped body B
Is reliably stopped by pressing the stopper B. After such a state is ensured, the motor 54 of the wire operating device 5 operates in reverse rotation to pull back the wire 3 previously sent into the long tube. Since the hook-shaped head 43 of the stopper 4 locks the rod-shaped body B, the pull-back of the wire 3 causes the clip 31 to come off from the rod-shaped body B (FIG. 11). Thus, the wire 3 returns to the original position. Then, after a series of operations stopper 4 is retracted to its original position, the rod-like body B is to be disposed from the elongated tube end a predetermined distance L _1. By simply turning on the start switch, the operations up to this point are performed in sequence by sequence control.

Next, the worker uses the air vent hole O to inject the adhesive S, and adhesively fixes the positioned rod-shaped body B to the long tube (FIG. 12). This operation may be omitted as long as the rod B is not displaced in the long tube.

Thereafter, another rod B is
A predetermined distance L ₂ from the end of the long tube according to the above procedure
(FIG. 13 (b)). Another proximity switch 7 is attached to the protection tube 6 so that it can correspond to the set position of the other rod B. Actually, the proximity switch 7 is provided at a plurality of positions so as to be applicable to various types of vehicles.
Is provided. Insertion of the rod-shaped body B into the long tube
At first glance, it seems that the ejector suction is difficult because one rod-shaped body B is already contained. However, there is a gap between the long tube T and the rod-shaped body B (FIG. 12). Since the air vent hole O is previously opened, the rod-shaped body B on the second surface can be sucked into the long tube only by ejector suction. If the second rod-shaped body B is shorter than the first rod-shaped body, the second rod-shaped body B may be inserted into the long tube T only by suction of the ejector 2 without stopping on the clip 31. Thus, the two rods B are inserted and set in the elongated tube T. In the present embodiment, the drain tube K is further formed in the elongated tube T. After the insertion and setting of the two rods B, the pin 82 is raised by operating the air cylinder 81, and two drain holes K are opened in the long tube T (FIG. 13).

In the insertion machine configured as described above, the rod B can be easily inserted into the long tube by the ejector 2. Then, the wire 3 is accompanied by the rod-shaped body B by clamping the clip 31 at the distal end of the wire to the rod-shaped body B. Further, when the rod-shaped body B comes to a predetermined position of the elongated tube T, the wire 31 is attached to the rear end of the wire. Since the attached metal element 33 stops the wire operating device 5 so as to be detected by the proximity sensor, it is possible to accurately set the rod-shaped body B on the long tube T. There is no difficulty even if the rod B is long. If the rod-shaped body B is manually sucked by the ejector 2, the rear part of the rod-shaped body is clamped by the clip 31, and then the start switch is turned on, a series of operations are automatically performed, so that the operation is quick and accurate.
Of course, as in the past, the number of places that rely on human resources is reduced, and labor saving is greatly advanced. Further, since the ejector suction is assisted by sending out the wire 3 of the wire actuator 5, even if the rod 3 is attached to the rod B, the rod B can be smoothly inserted into the long tube. In addition, even if a plurality of rods (two or more) are inserted into the long tube, the insertion procedure is basically the same, and the rod can be easily set at a predetermined position. Demonstrate freely.

In the present invention, the present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the present invention depending on the purpose and application. Ejector 2, wire, stopper 4,
The shape, size, material, and number of the wire actuator, the protection tube 6, the distance sensor, and the like can be appropriately selected according to the application. The shape of the clip 31 is not limited to the embodiment, and may be any shape as long as it can be locked to the rod-shaped body B. In the above embodiment, the rod-shaped body B
Although two rows of insertion equipment are provided, the number of rows can be one or three or more. The long tube T and the rod B are not limited to the rubber long tube and the sponge rod of the front door opening trim according to the embodiment, but may be any form of the long tube T and the rod B.

[0023]

As described above, the rod inserting machine for a long tube according to the present invention can easily and quickly operate even if the rod is long or a plurality of rods are set in the long tube. Since the rod-shaped body can be set at a predetermined position of the long tube with high accuracy, it is very effective in improving workability and quality.
