[Conventional technology]

Recently, a paper container 1 having a spout 2 as shown in FIG. 10 has been widely used. To attach the spout 2 to the paper container 1, a spout 2 having a flange 3 and a tubular portion 4 is prepared in advance as shown in FIG. The tubular portion 4 of the outlet 2 is passed from the inside of the paper container 1 through a hole formed in the paper container 2, and the flange 3 is joined to the wall of the paper container 1 by heat sealing. In the conventional apparatus for carrying out this process, the spouts are guided side by side in the chute so that they are in contact with each other, and the spouts that have reached a predetermined take-out position are sucked and held by the vacuum pad and pulled out from the chute, On the other hand, in the chute, after one spout is pulled out by the vacuum pad, the spouts lined up on it are moved by their own weight, and the next spout reaches the take-out position. Thereafter, the same operation is repeated to insert the spout.

[Problems to be solved by the device]

However, according to this structure, when the outlet in the chute is held and pulled out by the vacuum pad, the next outlet is placed on the outlet, so that the resistance when pulling out is largely removed from the vacuum pad. Or, there was a problem that the next spout was pulled by the spout that was pulled out by a vacuum pad and spilled from the chute.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a pouring outlet supply device that enables a pouring outlet to be stably taken out by a vacuum pad and attached to a paper container.

[Means for Solving the Problems]

The present invention, which has been made to achieve the above-mentioned object, has a chute having a spout with flanges arranged side by side so as to be in contact with each other and having a spout outlet at the lower end, and a chute disposed at the lower end of the chute. A slider provided in a housing for receiving one spout from the outlet, and a slider for moving the slider to a spout receiving position where the housing is aligned with the outlet of the chute and a pouring out position separated from the outlet. From the drive unit and the slider that has moved to the pouring outlet extraction position, the pouring outlet held by the slider is taken out by suction holding the surface on the side provided with the flange, and the pouring outlet is set to the inner surface of the paper container. Side has a vacuum pad to be inserted into the spout insertion hole, and when the slider is out of the spout receiving position, pouring from the chute delivery port Front plate that has a stopper surface for preventing the falling of the spout, and further supports a part of both ends of the flange of the spout so that the slider is on the front surface and the spout stored in the storage part does not fall from the front surface. The gist is a spout supply device characterized by having.

[Action]

In the spout feeder having the above-mentioned configuration, when the empty slider moves to the delivery port receiving position where the accommodating part is aligned with the chute delivery port, the bottommost spout in the chute enters the slider by its own weight, Next, when this slider moves laterally, the stopper face of the slider prevents the outlet in the chute from falling, and moves the outlet held inside the slider away from the outlet in the chute to the outlet extraction position. Let At this time, since the front plate provided on the front surface of the slider restrains part of both ends of the flange of the spout housed in the housing part, the spout may fall or tilt from the front surface while the slider is moving. There is no such thing, and it is maintained in a predetermined posture.

When the slider holding the pouring outlet stops at the pouring outlet taking-out position, the pouring outlet held by the slider is taken out by suction holding the surface on the side where the flange is provided by the vacuum pad. At this time, since the spout is held by the slider in a predetermined posture and is separated from the spout in the chute, the pouring and holding of the spout by the vacuum pad is reliable, and
No troubles such as dropping out of the spout in the chute. The spout taken out by the vacuum pad is then inserted from the inner surface side of the paper container into the spout insertion hole formed in the paper container by the vacuum pad, and the paper container is sent to the next sealing process.

〔Example〕

An embodiment of the present invention shown in the drawings will be described below. FIG. 1 is a front view showing an outlet supply device according to an embodiment of the present invention,
FIG. 2 is a plan view showing the device with the chute removed,

This device is for sucking and holding the spouts 2 shown in FIG. 11 one by one with a vacuum pad and supplying them to the paper container, and 11 is a chute for guiding the spouts. As shown in the cross section in FIG. 4, this chute 11 has a groove 12 for guiding the tubular portion 4 of the spout 2, a guide surface 13 for guiding the straight portion of the flange 3 of the spout 2,
The spout 2 has a holding member 14 provided along the front surface of the groove so as not to fall out of the groove 12 toward the front, and at least the vicinity of the lower end thereof is provided substantially vertically as shown in FIG. As shown in FIGS. 5 and 6, a large number of spouts 2 are guided in the chute 11 side by side so that their respective flanges are in contact with each other. The upper outlet is designed to move under its own weight. A feeder that continuously supplies the spout is connected to the upper end of the chute 11.

1 to 4, the lower end of the chute 11 is the spout 2
It is the outlet 15 of the spout so that it can pass freely. At the lower end of the chute 11, there are provided a slider 17, a guide shaft 18 that holds the slider 17 laterally movable with respect to the chute 11, an air cylinder 19 that reciprocates the slider 17, and the like. This slider 17 is a receiving portion 21 that receives the one spout at the lowermost end from the chute 11.
The main body 20 having the above-mentioned structure, the position-adjustable stopper 22 that supports the tubular portion of the spout that has entered the accommodating part 21, and the flange of the flange so that the spout contained in the accommodating part 21 does not fall from the front surface. It has a front plate 23 (see FIG. 2) that supports a part of both ends, and a protrusion 24 having an upper surface 24A that extends laterally in the same plane as the upper surface 20A of the main body 20. A taper is formed at the upper end of the housing portion 21 so that the spout 2 can smoothly enter from the chute 11. The stopper 22 is shown in Fig. 5,
As shown in FIG. 6, when the tubular portion 4a of the spout 2a is supported thereon, the lower end of the tubular portion 4b of the spout 2b located immediately above the spout 2a is located on the upper surface 20A of the main body 20A of the slider 17. Also, the position is adjusted so that the height is substantially matched with the upper surface 24A of the protrusion. Therefore, when the slider 17 is moved as shown in FIG. 8, the lowermost spout 2b in the chute 11 is supported by the upper surface 20A of the slider body 20 and the upper surface 24A of the protrusion 24 and falls from the chute 11. There is no such thing. This side 20A, 24
A constitutes a stopper surface for preventing the chute 11 from falling from the chute 11 through the chute 11. A slit 20B is formed on the upper surface of the main body 20 of the slider 17 so as not to interfere with the flange of the spout 2b held in the chute 11 when the slider 17 moves. The air cylinder 19 receives the slider 17 at a receiving position in which the accommodating portion 21 is aligned with the outlet 15 of the chute 11 (the position indicated by the solid line in FIGS. 1 and 2).
And a slider driving device that acts so as to be moved to a take-out position (position indicated by a chain double-dashed line in FIG. 2) that is out of the delivery port 15. In FIG. 2, 26 is a slider 17
It is a vacuum pad that takes out the inside of the spout by suction holding the surface on the side where the flange is provided, and inserts the spout into the spout insertion hole from the inner surface side of the paper container.

Next, the spout supply operation by the above device will be described. First, as shown in FIGS. 5 and 6, it is assumed that the accommodating portion 21 of the slider 17 is aligned with the lower end of the chute 11. In this state, a large number of spouts 2 are stacked in the accommodating portion 21 and the chute 11 with their flanges in contact with each other.
Next, the air cylinder 19 operates to move the slider 17 to the first position.
Move to the left in Figs. By this movement, the spout 2a held by the slider 17 is separated from the lowest spout 2b in the chute 11 and moved to the take-out position as shown in FIG. At the time of this movement, the spout 2b in the chute 11 is supported by the stopper surfaces 20A and 24A and therefore does not fall. Further, since the spout held by the slider 17 is constrained by the front plate 23 at a part of both ends of the flange, it does not fall or tilt from the slider 17 and always maintains a fixed posture. When the slider 17 reaches the extraction position of the spout, the vacuum pad 26 moves to the position of the spout 2b in FIG. 2 to suck and hold the spout 2b, and then moves to the original position and holds it. Take the exit 2b from the slider 17 toward you. At this time, a single spout is held in the slider 17 in a fixed posture, and since the spout is separated from other spouts in the chute 11, this pouring is performed by the vacuum pad. It can be surely sucked and held to be taken out, and the spout in the chute is not adversely affected by taking out by the vacuum pad. In addition, the spout in the slider 17 has a part of its flange restrained by the front plate 23.
There is no problem in taking out.

After taking out the spout, the slider 17 returns to the original spout receiving position (the position shown in FIGS. 5 and 6) by the air cylinder 19. At this position, the spout in the chute 11 moves by its own weight, and the spout at the bottom end is housed in the slider 17. After that, by repeating the same operation, the spouts are successively supplied to predetermined positions taken out by the vacuum pad 26.

FIG. 9 shows a vacuum pad 26 for the spout 2a of the slider 17.
It is a figure which shows the operation | movement which takes out by and is inserted in a paper container.

In (A), the paper container 1 having the spout insertion hole 6 stands by at a position where the movement of the vacuum pad 26 is not hindered. When the slider 17 holding the spout 2a moves to the take-out position, the vacuum pad 26 moves in the direction of arrow A to reach the position shown by the chain double-dashed line, and suction-holds the spout 2a. Next, the vacuum pad 26 holding the spout 2a moves to the position shown in (B), and the spout 2a is taken out from the slider 17. After that, the paper container 1 moves in the direction of arrow B,
As shown in (C), it stops at the position where the spout insertion hole 6 and the spout 2a are aligned. Next, the vacuum pad 26 holding the spout 2a moves in the direction of arrow C and the spout 2a is inserted into the insertion hole 6. After that, the vacuum pad 26 releases the suction of the spout, and the paper container 1 moves in the direction of arrow D,
It is sent to the sealing process of the spout flange.

[Effect of device]

As described above, the spout supply device of the present invention is arranged in a state in which the spouts are in contact with each other in the chute, and receives one of the lowest ends of the spouts sent to the slider and removes the slider from the chute. Since it is constructed such that the spout in the chute is supported by the stopper surface provided on the slider, the spout held by the slider can be separated from the spout in the chute. , The pouring outlet in the slider can be reliably taken out by the vacuum pad without any adverse effect on the pouring outlet in the chute, and the pouring outlet taken out by the vacuum pad is inserted into the pouring outlet insertion hole of the paper container. It has the effect of being able to. In addition, the slider is equipped with a front plate so as to constrain both ends of the flange of the outlet held, so the outlet may drop from the front while the slider is moving,
Since it maintains a certain posture without tilting, it also has the effect that it can be reliably sucked and held by the vacuum pad and taken out.
