Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an article supply device that supplies articles such as caps to a capper etc. using air, and more specifically, relates to an article supply device that supplies articles such as caps to a capper etc. The present invention relates to a leftover article discharging device capable of discharging leftover articles.

[Prior Art] Conventionally, as an article supply device for supplying an article such as a cap to a capper or the like using air, a hopper that stores the article,
There is known a device equipped with a Syntron feeder that advances articles dropped from the hopper by vibration (Japanese Patent Publication No. 35753/1983).

In this type of article supply device, when changing the article to be conveyed, it is necessary to discharge all the articles in the hopper, and for this purpose, for example, the article supply device is connected with the Syntron feeder connected to the collection section. By operating the hopper, all the items in the hopper are collected into the collection section.

[Problems to be Solved by the Invention] However, since the above-mentioned syntron feeder advances the articles by vibration, it is not possible to reliably push out all the articles, and there is a risk that the articles may remain on the synthron feeder. . For this reason, in the past, it was necessary to check whether the product remained on the Syntron feeder each time the product was changed, and this work was complicated, and due to a confirmation error, the product before the change could be placed in the product after the change. Sometimes they mixed together and caused trouble.

In view of such circumstances, the present invention provides a residual article discharging device for an article supply device that can reliably extrude articles from above the Syntron feeder.

[Means for Solving the Problems] That is, the present invention provides the above-mentioned article supply device with a push-out member that is moved forward and backward by a drive means and pushes out the article that has been dropped from the hopper onto the Syntron feeder,
Moreover, this extrusion member is provided with an air injection port for blowing away the article in the extrusion direction.

[Operation] According to the above configuration, when changing the article to be transported,
If the driving means is actuated to advance the pushing member,
Since the articles on the Syntron feeder can be reliably extruded, it is possible to prevent the articles before the change from being mixed in the articles after the change. When extruding the article with the extrusion member,
Since the article can be blown away in the extrusion direction by air from the air injection port provided in the extrusion member, it is possible to prevent the article from being caught between the Syntron feeder and the extrusion member.

[Example] The present invention will be described below with reference to the illustrated embodiment. In the embodiment shown in FIG. The system is equipped with hoppers 2A and 2B that contain hoppers 2A and 2B, and syntron feeders 3A and 3B that use vibration to advance the caps that are dropped and supplied from the hoppers 2A and 2B. Connecting chute 4.

Valves 5A and 5B are provided at the connections between each syntron feeder 3A and 3B and the air chute 4, respectively, and by alternately opening and closing each valve 5A and 5B with air cylinders 6A and 6B, one syntron feeder is connected to the other syntron feeder. The cap can be supplied to the air chute 4 from 3A and 3B.

The air chute 4 has one end connected to a turbo blower 8 via a valve 7, and the operation of the turbo blower 8 causes the air sucked through the filter 9 to be discharged into the air chute 4, and the syntron feeder 3A, 3B
It is now possible to transport caps supplied from

The other end of the air chute 4 is branched into two parts via a flow path switching valve 11, and a cyclone 12 is connected to one end, and a collection hopper 13 is connected to the other end. The cyclone 12 is connected to a hopper 15 of a sorter that aligns the caps via a cyclone valve 14 as is conventionally known.
is connected to. In FIG. 1, 16 is an exhaust valve that is opened and closed by an air cylinder 17, and 18 is a dust collector.

Therefore, the article supply devices IA and IB are moved forward and backward by the air cylinders 21A and 21B as driving means, respectively, and are dropped from the hoppers 2A and 2B onto the syntron feeders 3A and 3B. As shown in FIG. An air injection port 23 is provided to blow the air toward.

Further, each air cylinder 21A, 21B is provided with a sensor 24 for detecting the forward end position and the backward end position of the extrusion members 22A, 22B, and each hopper 2A,
A sensor 25 detects that the inside of 2B is empty.
has been established.

According to the above configuration, when caps of a different type are to be supplied to the cyclone 12 from the other article supply device IB while one article supply device IA is supplying caps to the cyclone 12, the flow path must first be switched. The air chute 4 is connected to the collection hopper 13 by switching the valve 11. As a result, the hopper 2A of the article supply device IA
The cap inside can be collected into the collection hopper 13 via the Syntron feeder 3A and the air chute 4.

When the sensor 25 detects that the inside of the hopper 2A is empty, the pushing member 22A
The air injection port 23 provided in the air injection port 23 is connected to a compressed air source (not shown), and the air cylinder 21A is operated to advance the extrusion member 22A toward the air chute 4. As a result, the caps dropped from the hopper 2A onto the syntron feeder 3A are blown away toward the air chute 4 by the air from the air injection port 23, and the caps that remained on the syntron feeder 3A for some reason are also blown away. It is forcibly pushed out into the air chute 4 by the pushing member 22A.

When the sensor 24 detects that the pushing member 22A has moved to the forward end position, the air cylinder 6A
The valve 5A is closed by the push-out member 22.
A is returned to its original rearward end position.

Note that the pushing member 22A may not be moved to the forward end position even after a certain period of time has elapsed after the air cylinder 21A is activated due to a cause such as the cap being caught between the Syntron feeder 3A and the pushing member 22A. In such cases, an alarm can be issued.

On the other hand, when the flow path switching valve 11 is switched and the air chute 4 is connected to the collection hopper 13, the cyclone 12 and the cap in the hopper 15 are also discharged in the same way as in the conventional case, and the other article supply device IB is also discharged. Hopper 2
A new cap to be supplied is supplied into B.

As described above, the hopper 2A of the article supply device IA
When all the caps inside are discharged and the valve 5A is closed by the air cylinder 6A, the flow path switching valve 11 is closed.
is switched to connect the air chute 4 to the cyclone 12, and then the valve 5B of the other article supply device IB is opened by the air cylinder 6B. This allows hopper 2
A new cap in B is now supplied into the cyclone 12 via the syntron feeder 3B and the air chute 4.

In the above embodiment, the types of caps stored in the hoppers 2A and 2B of the two article supply apparatuses IA and IB are different, but the caps are the same and the caps are stored at the same time from the two hoppers 2A and 2B. Of course, it is also possible to supply .

[Effects of the Invention] As described above, according to the present invention, it is possible to reliably extrude the articles on the Syntron feeder, thereby preventing the articles before the change from being mixed in the articles after the change. When extruding an article with the extrusion member, the article can be blown away in the extrusion direction by air from the air injection port provided on the extrusion member, so that the article is caught between the Syntron feeder and the extrusion member. This has the effect of being able to prevent this.
