Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a detachable device for gripping a cylindrical body such as a bottle (hereinafter referred to as an article) and discharging it at a predetermined position.

[Conventional technology]

An example of an attachment / detachment device for gripping an article to be supplied, transferring it to a predetermined position, and then releasing the article is one having a structure shown in FIG. However, this attachment / detachment device 50 shows an example of holding three articles W at the same time, and includes fixed pieces 51, 51, 51 facing each of the articles W, W, W, and movable pieces 52, 52, 52. The fixing piece 51 fixes the base end to the mounting base 53. The movable piece 52 has an intermediate portion pivotally supported by the mounting base 53, and the tension springs 54, 54, 54 constantly urge the tip end toward the fixed piece 51 side to elastically support the article W.

When the article W is received and released, the solenoids 55, 55, 55 provided at the other end of the movable piece 52 are operated to move the movable piece 52.
Means for moving the tip of the and moving it away from the fixed piece 51 is adopted.

[Problems to be solved by the device]

The conventional attachment / detachment device for the article W is provided with a fixed piece and a movable piece for each article, and is configured to operate for each movable piece, which has a complicated structure. Further, there is a problem that a certain distance or more is required between the articles due to the structure and the cost becomes high.

In view of the above points, the present invention has an object to have a simple structure, reliably hold a plurality of articles, and quickly receive and release the articles.

[Means for solving the problem]

The present invention has been made in order to achieve the above-mentioned object, and an article insertion hole for a bottle or the like is formed between a pair of sandwiching plates, and one sandwiching plate is attached to a conveying device as a fixed sandwiching plate, and the other sandwiching plate is formed. The plate is elastically supported by the fixed holding plate to elastically support the article to be inserted into the insertion hole, and the ejection mechanism provided with the extruding rod facing the insertion hole is disposed at the discharge position moved by the conveying device. Use as a summary.

[Action]

By simply pushing the article into the insertion hole between the pair of holding plates, the article is elastically held between the holding plates.

When reaching the discharge position in this state, the product can be easily discharged by inserting the extrusion rod of the extrusion mechanism into the insertion hole and pushing out the article.

〔Example〕

1 to 4 show an embodiment of the present invention. The figure shows an example in which the attaching / detaching device 10 of the present invention is applied to a conveying device 3 for supplying a plurality of, for example, three articles W sent by a supply conveyor 1 onto the other discharge conveyor 2.

That is, the attachment / detachment device 10 is provided with a gripping mechanism 11 attached to each of the four sides of the rectangular turntable 4 of the transfer device 3, and an extrusion mechanism 12 provided on the discharge conveyor 2 so as to face each other.

The gripping mechanism 11 forms an insertion hole 15 for the article W between the pair of sandwiching plates 13 and 14, and one sandwiching plate 13 is attached to the turntable 4 to form a fixed sandwiching plate. The other holding plate 14 has ammunition 16 on both sides.
As a result, the movable holding plate is elastically supported by the fixed holding plate 13. Reference numeral 17 denotes a bolt that is planted in the fixed holding plate 13 to support the ammunition 16.

The insertion hole 15 has a diameter slightly smaller than the outer diameter of the article W so that when the article W is inserted, it is pressed against the elastic force of the ammunition machine 16. Further, the insertion hole 15 is not necessarily limited to a circular hole when the article W is, for example, a cylinder, and may be formed so as to face each of the sandwiching plates 13 and 14 and form a triangle.

Further, it is preferable that at least one of the holding plates 13 and 14 is made of an elastic material such as synthetic resin.

The push-out mechanism 12 is a gripping mechanism 11 that faces the discharge conveyor 2.
Push rods 20 and 2 provided corresponding to the respective insertion holes 15, 15 and 15 of
0, 20, a connecting plate 21 for connecting the respective extruding rods and this connecting plate
It consists of a push-down cylinder 22 connected to 21. Reference numeral 23 is a guide plate for the push-out rod 20, and 24 is a guide member for inserting and supporting the guide rod 25 attached to the connecting plate 21.

Reference numeral 30 is a supply mechanism for supplying the article W on the supply conveyor 1 to the gripping mechanism 11. This supply mechanism 30 connects a push-up rod 31 provided corresponding to each insertion hole 15, 15, 15 of the gripping mechanism 11 facing the supply conveyor 1 by a connecting plate 32,
A push-up cylinder 33 is attached to the connecting plate 32. Reference numeral 34 is a push-up rod guide plate, and 35 is a guide member for inserting and supporting the guide rod 36 attached to the connecting plate 32.

In addition, the feed conveyor 1 has a through hole through which the push-up rod 31 is inserted.
Drill 40.

In the above structure, the article W on the supply conveyor 1 is pushed up by the push-up bar 31 of the supply mechanism 30 to form a pair of the sandwiching plates 1.
It is press-fitted into the insertion holes 15 of 3, 14 and then the push-up bar 31 is lowered.

Then, the turntable 4 is turned to hold the article W and hold it.
When 11 reaches the discharge conveyor 2, the push-down cylinder 22 of the push-out mechanism 12 is operated to lower the push-out rods 20, 20, 20 to push out the articles W in the insertion holes 15, 15, 15 and discharge them. Supply on the conveyor 2.

In the above-described embodiment, the article W is press-fitted into the insertion hole 15 by the push-up rod 31 as the supply mechanism 30. However, as another supply mechanism, the rotating table 4 itself of the transfer device 3 is provided with an elevating means. When the article W is received, the turntable 4 may be lowered to press the article W on the supply conveyor 1 into the insertion hole 15.

Further, the transporting device 3 has the structure in which the turntable 4 is used and the gripping mechanism 11 is rotated to move to the discharge conveyor 2 side.
This may be a reciprocating transition between the supply conveyor 1 and the discharge conveyor 2. Alternatively, the push rod 20 may be fixed and the turntable 4 may be raised to push out the bottle.

[Effect of device]

According to the present invention, an insertion hole is formed between a pair of holding plates, and one holding plate is elastically pressed against the other holding plate to elastically support the article inserted into the insertion hole. It is easy to insert and can be held securely,
Moreover, a large number of articles can be held in close proximity. Moreover, when discharging, the article may be pushed out by an extrusion rod, and the structure is simple.
