Description

[Detailed Description of the Invention] The present invention relates to a chute for putting the lid on the box body in a box storing crayons, etc., in which the lid and the box body are separated.

Conventionally, the automatic operation of closing the lid on a box containing crayons, etc., had to be done manually because it was extremely troublesome to accurately position the lid on the box, but this method is accurate and highly efficient. The drawback was that it required considerable skill to perform.

This invention can be closed efficiently with an extremely simple operation of fitting the box body on which the lid is placed onto the bottom of the chute, inserting the lid into the chute from above, and sliding the lid forward along the chute. It is designed so that it can be closed, thereby eliminating the drawbacks of the conventional method.

1 and 2 show a first embodiment of the present invention, and reference numeral 1 indicates both side walls 1a and 1 having a width that allows the lid 5 to fit therein.
This is a closing lid chute with a U-shaped cross section, which is formed by expanding the upper part of the bottom part 1c outward, and has rails 2a and 2b fixed to both sides of the bottom part 1c at a predetermined position.

Next, the lid closing work will be explained.

The box body 4 is fed into the lid-closing chute 1 in the direction of the arrow (see Fig. 3) by a feeding means (not shown) such as a belt conveyor placed at the rear of the lid-closing chute 1. The box body 4 fed into the box body 1 is pushed by a push rod 8 attached to a vertical shaft 6 of a robot tip arm (not shown) and is fitted between the rails 2a and 2b. The lid 5 is
It is fed by a feeding means (not shown) into the lid chute 3 disposed parallel to the lid closing chute 1, and when the lid 5 reaches a predetermined position in the lid chute 3, the robot tip arm The vertical shaft 6 was moved to a position above the lid 5, and the suction cup 7 attached to the vertical shaft 6 descended to adsorb the lid, and rose to be placed between the rails 2a and 2b of the lid-closing chute 1. The box body 4 is moved to a predetermined distance backward position as shown in FIGS. 4 and 5. At this point, the suction cup 7 stops its suction action, and the lid 5 falls downward along both side walls 1a and 1b of the closing chute 1, as shown in FIGS. 6 to 8.
The lower side of the rear wall 5a of the lid 5 is the bottom 1 of the closing chute 1
c, and the lower sides of both sides of the lid 5 are placed on the rails 2a,
2b, and the front part of the lid 5 is tilted upward. Next, when the push rod 8 attached to the vertical shaft 6 of the tip arm of the robot pushes the lid 5 forward as shown by the arrow, the lid 5 slides forward on the rails 2a and 2b as shown in FIG. 9, and as shown in FIG. As shown, the lower side of the front wall 5b of the lid 5 falls along the outer surface of the front wall 4b of the box body 4 and is placed over the box body 4.

11 to 13 show a second embodiment of the present invention, in which the lid closing chute 11 has rails 12 on both sides of the bottom.
a and 12b are arranged longer at the rear than in the first embodiment. Therefore, the rear wall 5a of the lid 5 is connected to the rails 12a, 1
2b and is pushed forward. Other operations are similar to those in the first embodiment. This second embodiment is suitable when the fitting gap between the lid 5 and the box body 4 is small.

In both the first and second embodiments, dropping the lid onto the box body or pressing the lid forward when closing the lid does not necessarily have to be done by a robot, and may be done manually.

According to this invention, the lid is fitted between the rails on both sides of the bottom of the box body and the closing lid chute, so if the lid is dropped along the upper side of the widened side walls, the lid and the box body will automatically match in the width direction. Therefore, the lid can be reliably closed simply by sliding the lid forward along both side walls of the lid chute, which simplifies robot or manual operations and improves work efficiency. .
