Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for stopping overturning containers provided on a conveyor that supplies containers to a container processing device such as a bottle washer.

[Prior Art] A bottle supply unit that supplies containers into a container processing device such as a bottle washer requires a mechanism that prevents overturned containers from entering the inside of the bottle washer or the like. Conventionally, an intrusion prevention mechanism is generally used in which a part of the bottle arrangement guide placed on the conveyor is bent to allow upright containers to pass through, but to stop containers that have fallen over at this bend. (Publication number 58-16974).

[The problem that the idea attempts to solve]

When the guide is provided with a bent part as in the conventional device described above, the width of the conveyor becomes significantly wider, and
The length of the guide must be increased, and depending on the shape of the container, it may not be able to perform its function satisfactorily.

The present invention has been devised to eliminate the above-mentioned drawbacks, and provides an overturning container stopping device that is small in size and can reliably prevent overturned containers from entering a bottle washer or the like.

[Means to solve the problem]

The overturning container stopping device according to the present invention is intended to stop an overturned container being conveyed between guides on both sides arranged on a conveyor. A projection protruding toward the guide side is provided, and a recess is formed at a position facing the projection of the other guide, and these projections and recess satisfy the following conditions.

C>D>B...(1) L>F or M>F...(2) However, B: Distance between the tip of the protrusion and the other side guide D: Maximum body diameter of the container C: The distance between the tip of the protrusion and the protrusion of the recess Distance to the nearest part F: Length of the recess L: Length of the large diameter part below the shoulder of the container M: Length from the shoulder of the container to the mouth [Function] When a container that is standing upright reaches the position where the protrusion is provided, it can pass through the protrusion by partially entering the recess, but a container that is falling cannot enter the recess. I can't do it, so I stop.

〔Example〕

The present invention will be explained below with reference to illustrated embodiments. FIG. 1 shows an overturning container stopping device according to an embodiment of the present invention, in which a plurality of basically straight guides 6 are provided on a conveyor 4 that conveys containers 2 along the traveling direction of the conveyor 4. are placed at equal intervals.
A passage 8 through which the container 2 is conveyed is formed by opposing surfaces 6a and 6b of each guide 6. The width A of the passage 8, that is, the distance between the opposing surfaces 6a and 6b of each guide 6, is slightly larger than the diameter D of the thickest part of the container 2.

A triangular small protrusion 10 projecting into the passage 8 is fixed on one surface 6b of the two guides 6 facing each other to form one passage 8. Further, on the surface 6a of the other guide 6, a recess 12 is formed at a position facing the projection 10, which is cut out to a depth approximately equal to the protrusion amount of the small projection 10.

The distance B between the tip of the protrusion 10 and the facing surface 6a of the guide 6 is smaller than the diameter D of the thickest part of the container 2. That is, the protrusion 10 is connected to the passage 8
The container 2 protrudes into the passageway 8 by a larger amount than the difference between the width A of the container 2 and the diameter D of the thickest part of the container 2. In addition, the recess 1
2 is formed in a circular arc having a radius C larger than the diameter D of the thickest part of the container 2, centered on the protrusion 10, and receding outward from points 12a and 12b where the guide 6 contacts. , Moreover, the length F of this recess 12, that is, the above-mentioned two points 12a, 1
2b is shorter than the length L of the large diameter part below the shoulder of the container 2 (see Figure 2), or
Length from shoulder to mouth of container (i.e. neck length)
It is shorter than M (see Figure 3).

The above relationship is expressed by the formula: C>D>B...(1) L>F or M>F...(2) However, B: Distance between the tip of the protrusion and the other side guide D: Maximum diameter of the container C: Distance F between the tip of the projection and the part of the recess closest to the projection: Length of the recess L: Length of the large diameter part below the shoulder of the container M: Length from the shoulder of the container to the mouth.

In the apparatus of this embodiment having the above configuration, the upright container 2 moves forward through the parallel, substantially linear guides 6, and when it reaches the part where the protrusion 10 and the recess 12 are located, the tip of the protrusion 10 and the recess 12 Point 1 on the entrance side of
2a is larger than the diameter D of the container 2, the container 2 is pushed by the protrusion 10 and a part of the container 2 is pushed into the recess 12.
After entering the inside, it comes out again onto the surface 6a of the guide 6 and is conveyed.

On the other hand, when the overturned container 2 is transported and reaches a position where the protrusion 10 and the recess 12 are located, the length L of the large diameter part below the shoulder of the container 2 or the length L from the shoulder of the container 2 to the mouth of the container 2 is determined. Since the length M is longer than the length F of the recess 12, and the distance B between the tip of the protrusion 10 and the other guide 6 is smaller than the diameter D of the container 2, the container 2 12 and stopped.

Since the overturned container 2 can be reliably stopped in this way, there is no fear that the overturned container 2 will enter a bottle feeding device such as a bottle washer. Moreover,
a small protrusion 10 in which a portion for stopping the overturning container 2 is fixed to one side of a parallel, substantially linear guide 6;
Since it is composed of a recess 12 formed on the other side and consisting of a notch with a depth approximately equal to the protrusion amount of this small protrusion, it is different from the conventional device (Utility Model Publication No. 16974/1983).
There is no need to increase the width of the conveyor compared to a conveyor with a bent portion, and the device can be made more compact. Further, it is only necessary to make slight changes to the guides that have been generally used in the past, and an increase in costs can be avoided. Furthermore, since an upright container has a small amount of lateral movement, it can achieve various effects such as being able to carry out stable transportation.

In addition, the size of the protrusion 10 and the recess 12,
The shape is not limited to those described above, and can be appropriately selected depending on the shape of the container 2 within a range that satisfies the above formulas (1) and (2). In addition, the above protrusion 1
An overturned container detection sensor may be provided at the 0 position or downstream thereof.

In this case, automatic operation of the device becomes possible.

[Effect of idea]

As described above, according to the present invention, it is possible to obtain a compact and reliable stopping device for overturning containers.
