Description

[Detailed Description of the Invention] [Prior Art] A pull-out type box consisting of an inner box and an outer box, the lid of which can be opened by pulling out both boxes relative to each other, for inserting an article into the inner box. Conventionally, the methods used have been to push the article into the inner box and then cover it with an outer box, or to insert the inner box into which the article has been inserted into the outer box.

[Problem that the invention seeks to solve]

However, in the conventional case, the inner box and outer box are sent via completely different routes and are completely separated. The drawback is that it is difficult to guide them. If the inner box cannot be guided exactly into the opening of the outer box, the opening of the outer box and the opening of the inner box will be misaligned, making it impossible to push the outer box or the inner box into the other side. In particular, the above-mentioned situation occurs frequently when the inner box is made to a size that prevents it from cluttering inside the outer box.

In order to prevent this, a special guide must be provided within the mouth of the outer box to guide the inner box tightly.

In addition, because boxes are generally made of cardboard, their precision is low and their sizes vary, and conventional devices cannot adequately handle this. This is all due to the method of closing the inner box and outer box, which were moved from being completely separated to being relatively close to each other.

The object of the present invention is to provide a device that can eliminate these drawbacks.

[Means for solving problems]

In order to achieve this object, in the present invention, the chuck 6 for holding the inner box and the holder 14 for holding the outer box are arranged to face each other, and the article delivery table 19 is placed above the holder 14 so as to be movable up and down. The holder 14 is rotatable about a shaft 15, and at least one of the holder 14 and the chuck 6 can be moved forward and backward in the horizontal direction. A pusher 18 is provided which operates toward the inner box held in the box.

[Effect]

In the device of the present invention, the inner box and the outer box are firmly held by the chuck 6 and the holder 14, and the inner box and the outer box are relatively pulled out at the same height. Since the outer box is rotated during insertion, the article can be smoothly inserted into the inner box held horizontally.

〔Example〕

The apparatus of the invention will now be described with reference to the accompanying drawings, which are exemplary embodiments.

FIG. 2 is an overall elevational view of the device according to the invention;
Immediately below a conveyor 1 for conveying empty boxes A, a frame 2 having a rectangular shape in plan view is provided so as to rotate about a shaft 3 from the position shown by the solid line in FIG. 2 to the position shown by the chain line in the same figure. The rotation of the frame body 2 is caused by, for example, the cylinder 4 [second
It is best to perform the operation as shown in the figure.

The conveyor 1 is of a type that moves forward and backward repeatedly, and a magazine is provided above it, and the empty boxes A are supplied standing up in this magazine.
When the first empty box is sent to a stopper (not shown), the conveyor 1 moves backwards to push back the second and subsequent empty boxes, and the first empty box is cut off.

As shown in FIG. 4, the frame body 2 is provided with two left and right slide shafts 5 in the front-rear direction, and a chuck 6 is attached to the distal end portion of the frame body 2 that projects outside.

As shown in FIGS. 5 and 6, the chuck 6 has a pair of gripping plates 6b, 6b on the upper and lower sides of one fixed base 6a.
The upper grip plate 6b moves up and down by the operation of the cylinder 6c, and the lower grip plate 6b
It is possible to change the interval between the two. In the embodiment, the shape of the pair of upper and lower gripping plates 6b, 6b is triangular so that they can fit into the notch b'' of the outer box b (Fig. It is possible to hold the inner box a.

On the other hand, as shown in FIG. 4, a screw shaft 7 is provided between the two left and right slide shafts 5, 5 on the inside of the frame 2, and parallel to the two slide shafts 5, and the movable base 8 is screwed onto the screw shaft 7. and attach the rear ends of the slide shafts 5, 5 to this. Further, the movable base 8 is loosely attached to a guide shaft 9 which is parallel to the slide shaft 5 and the screw shaft 7 and located directly below the slide shaft 5. Then, the screw shaft 7 is rotated forward and backward through a motor 10, pulleys 11 and 12, and a belt 13 fixed to the frame body 2. As a result, the movable base 8 moves forward and backward along the guide shaft 9, and accordingly, the slide shafts 5, 5 and the chuck 6 attached to the tip thereof can be moved forward and backward with respect to the frame 2.

In front of the chuck 6, a pair of upper and lower holders 14, 14 (FIG. 2) for holding the outer box is provided so as to face this when the chuck is in a horizontal position.
Both holders 14, 14 are arranged in a second position around the shaft 15.
It rotates from the position shown by the solid line in the figure to the position shown by the chain line in the figure. The rotation of both holders 14, 14 is as follows.
For example, this can be done by actuating the cylinder 16 (FIG. 2). In the embodiment, a case is illustrated in which the lower holder is fixed to a boss 15a fixed to the shaft 15.

The pair of upper and lower holders 14, 14 is fixed to the upper end of a vertical cylinder 17 with one of them (the upper side in the drawing) fixed to the lower holder, as shown in FIGS. The distance between the pair of holders 14, 14 can be changed.

A pusher 18 is provided on the sides of the pair of upper and lower holders 14, 14 at a horizontal position, that is, at a slightly higher position than the opposing chuck 6 for holding the inner box. The pusher 18 can advance from the position indicated by the solid line in FIG. 9 to the right in the same figure.

On the other hand, above the pair of upper and lower holders 14, 14, an article delivery table 19 is arranged horizontally, and the lower ends of elevating rods 21, 21, which are vertically movably inserted into a base 20 located above the table 19, are arranged horizontally. The article delivery table 19 is fixed. In addition, this goods delivery table 1
9 and a shaft 15 to which the lower holder 14 is fixed.
The shaft 1 is connected to the boss 15a by a lever 22.
The article delivery table 19 can be lowered as the holders 14, 14 rotate about the center 5.

In other drawings, 23 (Fig. 11) is a conveyor for taking out boxes, 24 is a stopper provided above the conveyor, and 25 (Figs. 7 to 11) is an article delivery table 1.
A stopper provided on the side of the item delivery table 19 (on the right side in Figures 7 to 11)
It serves to block the article B pushed into the container.

Next, the situation in which the article B is inserted into the inner box a of the pull-out box using the article insertion device in the above embodiment will be explained in order of steps with reference to FIGS. 1 a to 1 e.

By the operation of the cylinder 4, the frame body 2 rotates about the shaft 3 from a horizontal position to a position indicated by a chain line in FIG. At this time, the chuck 6 for holding the inner box is in the position shown in FIG.
The interval between the gripping plates 6b, 6b is wide.

At this moment, the motor 10 rotates in the normal direction, causing the screw shaft 7 to rotate in the normal direction via the belt 13, causing the chuck 6 to advance toward the frame 2 in the direction of the arrow in FIG.

Then, the two gripping plates 6 of the pair of chucks 6
b, 6b are located at the b'' part of box A at the top of conveyor 1 [Fig. 1 a], and the inner box a is covered by the outer box b.
hold.

At this moment, the cylinder 4 operates to rotate the frame 2 counterclockwise in FIG. 7. Therefore, the empty box A held by the chuck 6, which had been standing, is now laid down horizontally. Then, as the motor 10 rotates forward, the chuck 6 moves in the direction of the arrow in FIG. 7 (to the left in the figure) and pushes the empty box A between the pair of upper and lower holders 14, 14.

At this moment, the cylinder 17 operates and narrows the distance between the upper and lower pairs of holders 14, 14, so that the holders 14, 14 clamp the outer box b of the empty box A (FIG. 8).

At this moment, the motor 10 reverses, and the pulley 11,
12, the chuck 6 is moved backward with respect to the frame 2 via the belt 13 and the like. In this case, since the two gripping plates 6b, 6b are still holding the inner box a, as the chuck 6 retreats, the inner box a is moved as shown in FIG.
As shown in Figure 8, and as shown by the chain line in Figure 8,
The chuck 6 is pulled out from the outer box b, but when the tip of the opening a' is slightly inserted into the opening b' of the outer box b, the chuck 6 is stopped.

Then, at the next moment, the cylinder 16 is actuated to rotate the shaft 15 in the direction of the arrow in FIG. Then,
A holder 14 fixed to a boss 15a of a shaft 15,
14 is tilted as shown by the solid line in FIG. At this time, the holders 14, 14 are still holding the outer box b, so the outer box b uses the portion that engages with the tip of the opening a' of the inner box a as a fulcrum, as shown in FIG.
It is rotated as shown in Figure c. Therefore, the outer box b has been opened, and the opening a' of the inner box a held by the chuck 6 is exposed.

As the holders 14, 14 are tilted as described above, the article delivery table 19, which is connected to the holders 14, 14 via the lever 22, is lowered as shown in FIG.

When the article delivery table 19 reaches a point slightly higher than the height of the inner box a held by the chuck 6, the pusher 18 on the side moves in the direction of the arrow in FIG. Article B, such as a floppy stick, which had been previously stored inside, is pushed into the inner box a located at a slightly lower location. In this case, there are no guides on the left and right sides of the item B during transport, but the left and right side walls a'' of the inner box a,
a'' plays this role, allowing the article B to be reliably and smoothly pushed into the inner box a.

Next, the cylinder 16 is actuated to rotate the shaft 15 in the opposite direction. Then, the holder 14,
14 returns from the position shown in Fig. 9 to the state shown in Fig. 10,
The article delivery table 19 connected thereto also rises.

At this time, the holders 14, 14 are still holding the outer box b, so the outer box b is shown in FIG. It can be rotated like this.

At this moment, the motor 10 is rotated forward. Then,
The chuck 6 is advanced relative to the frame 2 via the pulleys 11, 12, the belt 13, etc., as shown in FIG.
Insert into outer box b. In this case, the middle box a
The tip of the opening a' is slightly close to the opening of the outer box b.
Because it is pushed in from the state inserted in b′,
When inserting the inner box a into the outer box b, there is no possibility that the openings of the two boxes will be misaligned.

As soon as the inner box a after inserting the article is inserted into the outer box b, the holder 1 is moved by the actuation of the cylinder 17.
The distance between 4 and 14 becomes wider and the outer box b is released.

At this moment, the motor 10 reverses. Therefore, the chuck 6 is moved back in the direction of the arrow in FIG. 10 (to the right) via the motor 10, pulleys 11, 12, belt 13, etc., and the box A' [FIG. 1 e] after the article has been inserted can be taken out. . When the chuck 6 moves back through the state shown by the chain line in FIG. 11 to the position shown by the solid line in FIG.
the two gripping plates 6b, 6 of the chuck 6.
When the interval b is widened, the box A' with the articles inserted, which has been held until now, is dropped onto the conveyor 23 through the state shown by the chain line in FIG. 11, and is taken out from the apparatus by its drive.

By repeating the above operations, conveyor 1
Automatically opens a drawer-type empty box A that is fed into the magazine in an upright position, inserts item B into the inner box a, closes the outer box b again, and discharges this box out of the machine. can be done automatically.

In the embodiment, two gripping plates 6 of the chuck 6
b, 6b and the holders 14, 14 are arranged so as to form an upper and lower pair. This is inner box a and outer box b
This is to grip the upper and lower wide surfaces of the 6b and to make the gripping state particularly strong, but the two gripping plates 6b,
6b and the holders 14, 14 may be provided to face each other on the left and right to sandwich the left and right surfaces of the inner box a and the outer box b.

In addition, in the embodiment, the chuck 6 for holding the inner box was made to move forward and backward, and the holders 14, 14 for holding the outer box facing it were not moved forward and backward, but conversely, the chuck 6 was made to move forward and backward. If not, the holders 14, 14 may be movable forward and backward, or both may be movable forward and backward.
In short, it is sufficient if the inner box a and the outer box b can be moved relatively closer to each other or farther apart. In addition, in order to make the holders 14, 14 move forward and backward, the shaft 15
Although it is necessary to make all of these items moveable, it goes without saying that the present invention can include these items.

In addition, in the above embodiment, the pull-out box is described as a type in which the inner box a fits completely inside the outer box b, but this type of box is the only one that can be handled in the present invention. It is not limited. A type in which the inner box a and the outer box b are approximately the same size, and when the opening of the inner box a is inserted into the outer box b, the two boxes hug each other and become approximately twice the size. It may be. Regardless of the format, the main thing is that it consists of an inner box and an outer box, and can be opened by pulling out both boxes relative to each other.

〔Effect of the invention〕

According to the device of the present invention, since the inner box and the outer box are held by the chuck and the holder, there is no need for a guide for guiding the box, and the size is the same as when the guide is provided. This machine does not have the disadvantage of being able to handle only 100 boxes, and it becomes possible to handle various boxes of different sizes with one machine. Further, according to the device of the present invention, the inner box a and the outer box b are pulled out relatively at the same level, the outer box b is rotated, and then the article is inserted into the inner box a held horizontally. However, since the outer box b is returned to its original position again, it has the effect of not taking up much space.
