Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an article positioning mechanism for a conveyor that positions articles such as containers continuously conveyed by the conveyor at predetermined intervals. .

[Conventional technology]

Containers supplied to a container processing machine such as a filling machine must be lined up at predetermined intervals depending on the function of the processing machine before being fed. Conventionally, containers are conveyed continuously by a conveyor. The containers were arranged at predetermined intervals using a star wheel, timing screw, etc. provided on the side of the conveyor.

[Problem that the invention attempts to solve]

However, with the above-mentioned spacing adjustment mechanism, it may be difficult to align containers etc. accurately at equal intervals, and therefore, it is difficult to align containers etc. at equal intervals. Problems have arisen when the intervals between the supplied containers must be perfectly matched.

The present invention was developed to eliminate these drawbacks, and allows containers that are continuously conveyed by a conveyor to be fed to a container processing machine after accurately adjusting the spacing. It provides an article positioning mechanism.

[Means for solving problems]

The article positioning mechanism according to the present invention is provided with engaging members that protrude onto the conveyance surface of the conveyor and can engage with the articles being conveyed at predetermined intervals while the conveyor is moving, and guides that guide the sides of the articles. A curved portion is formed in the member, and a dead plate is placed on the conveyor at the portion where the curved portion is provided.

[Effect]

In the positioning mechanism according to the present invention, the speed at which the articles are conveyed is limited by the curved portion of the guide member, and a braking action is applied by the dead plate to cause each engaging member to engage with each article, These articles are positioned at intervals between the engaging members.

〔Example〕

The present invention will be explained below based on the illustrated embodiments.
Figures 1 and 2 show a case in which a positioning mechanism according to an embodiment of the present invention is applied to a conveyor of a line-type filler (filling machine). Figure 1 is a plan view, and Figure 2 is a side view. It is a diagram. In the figure, reference numeral 1 denotes a conveyor consisting of a lift link chain. Although the details are not shown, a conveyor surface 2 for conveying articles such as containers is formed by a large number of slats attached to the top surface of this lift link chain. , among these many slats, one slat 3 is placed at every other location (for example, every 3 locations).
is attached to an arm 4 which is swingably supported by a pin of the chain, and when the arm 4 is pushed up by a cam 5 arranged below the conveyor 1, the slat 3 is moved above the conveying surface 2. (See Figure 2). The container 6 transported by the transport conveyor 1 is filled with liquid through a plurality of nozzles 7 arranged at predetermined intervals, as is well known in the art.

A guide member 8 is arranged above the conveyor 1 and guides both sides of the container 6 conveyed by the conveyor 1. This guide member 8 is provided with a curved portion 9 slightly downstream of the position where the floating slat 3 is raised by the cam 5. Further, a dead plate 10 made of a thin plate material is provided on the conveyor 1 in a portion where the curved portion 9 is provided.
The tip of the container 6 is located within the travel path of the container 6 guided by the guide member 8. Also, 1
Reference numeral 1 denotes a rotary wrist puller that separates containers 6 that are continuously conveyed on the conveyor 1 at regular intervals.

To explain the operation of the above-mentioned device, the containers 6 which are continuously conveyed in a contacting state are separated by a rotary wrist puller 11 at a constant interval. Two containers 6, 6 given a certain distance in this way
Meanwhile, the floating slat 3 is raised by the action of the cam 5. When each container 6 reaches the curved part 9 of the guide member 8, the container 6 detours and advances, so the relative speed of travel to the conveyor 1 decreases, and the brake is applied by the dead plate 10, so each container 6 The rear floating slat 3 catches up, and the front end surface of the floating slat 3 engages with the rear surface of the container 6, pushing the container 6 forward from the rear. In this way, by advancing the containers 6 by the floating slats 3, the containers 6 are always positioned and transported at intervals equal to the spacing between the floating slats 3. Therefore, if the spacing between each floating slat 3 and the spacing between each nozzle 7 are matched, there is no risk of filling errors or the like. Note that the shape of the curved portion 9 is not limited to that shown in FIG. 1, but it goes without saying that even if the container 6 is pressed by the floating slat 3, no jamming will occur. Furthermore, the floating slat 3 is not limited to the above-described shape, but may be any shape as long as it can protrude above the conveyance surface 2 of the conveyor 1 and engage with the container 6.

Note that the rotary wrist stopper 11 can also be replaced with a timing screw or the like.

[Effect of idea]

As described above, the present invention has a simple structure in which a part of the guide member originally required for the conveyor is curved, and a dead plate is placed on the conveyor in the part where the curved part is provided. , articles such as containers can be reliably positioned at regular intervals. Further, it is possible to easily accommodate containers of different sizes by changing the widths of the pair of guide members.

Claims (1)

[Scope of utility model registration request] In a conveyor that conveys an article such as a container while guiding the side surface of the article by a guide member, engaging members that protrude onto the conveying surface of the conveyor and can engage with the article are provided at predetermined intervals while the conveyor is moving. and forming a curved portion on the guide member,
By detouring the article through this curved part, the conveyance speed of the article is made low relative to the conveyor, and a dead plate is placed on the conveyor in the part where the curved part is provided, and the article passes through this dead plate. An article positioning mechanism for a conveyor, characterized in that articles continuously conveyed by the conveyor are positioned at intervals between the engaging members by limiting the conveyance speed of the articles.
