Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for attaching a tube holding plate to the base of a tube and the vicinity of the P float for holding the vicinity of the base of a tube contained in a packaging container. It is.

When storing bulbs such as light bulbs, which have traditionally been stored in cylindrical packaging containers, in an outer box, the area around the base of the bulb tends to become unstable due to shocks and vibrations during transportation, which can cause damage. Therefore, to prevent this, place tri-! in a cylindrical container near the mouthpiece. The tube holding plates are attached so that they fit together.

Conventionally, the work of attaching the bulb holding plate near the base of the above-mentioned light bulb was done by hand.

This not only requires a large number of workers.

It was difficult to improve productivity.

The present invention provides a device for attaching a tube holding plate to a tube, which can save labor and improve productivity.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an apparatus that is an embodiment of the invention.

In the figure, an outer box 1 stores a plurality of tubes such as light bulbs, each of which is housed in a cylindrical packaging container, and is connected to four groups of tube holding plates by an attachment 3 attached to a chain 2. Each tube tube 2 is sent a fixed distance through a chain sprocket (not shown) by an intermittent drive reducer (not shown) receiving a transmission from a motor (not shown).

Attachments 3 are provided for each feeding interval. The signal to send this chain 2 is generated when the outer box 1 is fed into the guide rail 6.

- A plurality of holding mechanisms 6 for stacking and holding the tube holding plates 4 are provided on the fixing base 7 adjacent to the stop position of the outer box 1. Although the tube holding plate 4 is held by all the holding mechanisms 6, FIG. 1 shows the tube holding plate 4 being held by only two of them for convenience. In addition, the suction mechanism 8 that suctions the tube holding plate 4 is a compressor (
It is supported by an air slide unit 9 driven by high-pressure air from a source (not shown), and reciprocates between the stop position of the outer box 1 and the holding mechanism 6.

Details of the holding mechanism 6 and suction mechanism 8 are shown in FIG. That is, first, the holding mechanism JP-A-58-1
34823(2) 6 is a pedestal 9 for a tube holding plate provided on the fixed base 7.
Compression spring 10 placed inside this. and a guide rod 12 whose lower end abuts the compression spring 1o and whose upper end extends upward through a hole 11 provided at the top of the base 90. A projection 13 is provided at the top of the pedestal 9, and the tube holding plates 4 inserted into the guide rod 12 are stacked at an angle. It goes without saying that by making the top of one pedestal a slope, the tube holding plates 4 can be stacked at an angle in the same manner as described above.

Next, the suction mechanism 8 includes an air cylinder 14 (see FIG. 1) driven by high-pressure air from a compressor;
A suction pipe 16 connected to a vacuum pump and having its tip branched into three directions at angles of about 12Q degrees, and a metal plate 17 having a kite hole 16 so that the upper end of this suction pipe 16 can be slid up and down. ．． It consists of a compression spring 18 provided at the upper end of the suction pipe 16, and a regulating part 19 provided at the upper side of the four internal parts of the suction pipe 16 branched into three directions to regulate the position of the mouthpiece of the tube. .

In FIG. 2, the spring force of the compression spring 15 is stronger than that of the compression spring 1o. Therefore, when the restriction part 19 of the suction mechanism 8 is lowered together with the suction pipe 16, this restriction part 19 acts on the guide rod 12. Since it comes into contact with the head and pushes it down, even if the number of tube holding plates 40 held by the guide rod 12 decreases, the tube holding plate 4 will always be suctioned by the suction pipe 16. .

The operation of the device described in item 1 will be explained next.

First, the air slide unit 9 is driven by high-pressure air, and the suction mechanism 8 group moves in the direction of arrow A and stops at a position directly above the holding mechanism 6 group. At the same time, the air cylinder 14 is similarly driven to lower the suction mechanism 8 group. Then, as shown in FIG. 2, two of the three suction pipes 16 come into contact with the tube holding plate 4 first, and a little later than the remaining one, this tube holding plate 4 comes into contact with the vacuum suction force. It is removed from the body. In this way, the reason why the tube holding plates 4 are sucked one by one by the suction pipe 16 is because the tube holding plates 4 are installed at an angle. At the same time, the tube holding plate 4 is attached to the suction pipe 16.
is not adsorbed, and the tube holding plate 4 is first adsorbed to one or two of them, and this tube holding plate 4 is adsorbed to the remaining one a little later, so that this tube holding plate 4 is Gradually away from the end against the tube holding plate located on its back side.

As the vacuum state is broken, 1t++1 on the other side is 5n.

This is thought to be because the primary tube holding plate is not attracted.

If you stack the tube holding plates horizontally and place them on the market,
When the tube holding plate is suctioned with a suction vibrator, the tube holding plate on the front side is also almost entirely in a vacuum state, so it is attracted to the suction pipe and the tube holding plate is attracted to the stave. Then, the two tube holding plates are suctioned at the same time.

Now, the suction mechanism 8 group is raised by the air 7 cylinder 14, is further driven by the air slide unit 9, moves in the opposite direction (direction of arrow B), and stops at the position shown in FIG. At the same time, the air cylinder 3 is also driven, and the suction mechanism 8 group descends in the direction of arrow C. Then,
The cap of the tube is inserted into the hole provided in the center of the tube holding plate 4, and then the suction of the tube holding plate 4 by the vacuum of the suction vibrator 16 is stopped. And air cylinder 14
As a result, the holding mechanism 8 is raised in the direction of the arrow, and the plate 4 is attached. At the time of C, the cap portion of the bulb 19 is regulated at a predetermined position by the recessed portion of the regulating portion 19 of the suction mechanism 8. Each packaging container 18 in FIG. 3 is shown in FIG. 4, and the bulb 19 consists of a valve part 20 and a cap part 21. In addition.

The edges of the holes in the tube holding plate 4 are cut radially, so that the tube holding plate 4 can be easily attached to the tube 19, and the tube 19 can be easily attached to the tube 19 after being attached. This ensures that the tube holding plate 5 can be held securely.

9, it is moved directly above the holding mechanism 6 again. Meanwhile, during this time, the attachment 3 of the chain 2 moves to carry the primary outer box 1. Thereafter, the tube holder &6 is attached to the vicinity of the mouthpiece 21 of the tube 19 housed in the cylindrical packaging container 18 by the same operation as described in ``-''.

The holding plate can be installed automatically, and the suction mechanism can pick up 91 tube holding plates that are stacked up, making it possible to install them accurately. Therefore, manpower can be saved and productivity can be greatly improved compared to the conventional method.
