Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an article sending conveyor, an article receiving conveyor which is arranged in parallel with the article sending conveyor and is driven in the same running direction as the conveyor, and a conveyor which is driven from above the article sending conveyor onto the article receiving conveyor. In the conveyor device, the article sending conveyor is provided with a plurality of shaft rods, each of which has a plurality of rollers rotatably fitted therein. This invention relates to a roller conveyor device whose ends are connected in an endless manner.

A conventional conveyor system of this type is shown in FIG. In FIG. 1, 1 is an article delivery conveyor, 2 is an article receiving conveyor arranged in parallel with the article delivery conveyor 1, and 3 is an article, such as a beer bottle, for example.
The conveyors 1.2 are driven in the same direction of travel, indicated by arrow 4. Reference numeral 6 denotes a guide extending obliquely in the running direction from above the article sending conveyor 1 to above the article receiving conveyor 2, and is composed of left and right guide members 5 and 5B, and the guide is narrower toward the article receiving conveyor section. As a result, the number of rows of articles is reduced and becomes a single row. Such conveyor cylinders are required when it is necessary to convert articles from a multi-row conveyor into a single row, such as in front of an empty bottle inspection machine, in front of a filler, or in front of a labeler in a beer factory.

This conveyor device does not have much of a problem when the articles 3 are sent at intervals, but when the conveyor 1 has a large number of articles and is sent at close intervals, the articles 3 may be conveyed at the guide 5. A so-called bridging phenomenon occurs in which the articles 3 are pushed against each other and become clogged, and the articles 3 are not only damaged due to mutual friction, but also have the disadvantage that they are noisy and interfere with the operation of the conveyor device. That is, article 3 is guided by guide 5.
However, the surface of the conveyor, especially the article delivery conveyor 1, is flat and the frictional resistance with the bottom of the article 3 is large, and the article 3 cannot easily move with respect to the surface of the conveyor 1. When receiving a lateral force from the guide 6, the guide member 5m.

The guide members 5A and 5 are pressed against each other in the lateral direction between the guide members 5A and 5B.
This results in a situation where it is strongly sandwiched between B.

For this reason, attempts have been made to attach vibrators to the guide members 5A and 5B to loosen the article 3, or to make the guides into a solo bread shape, but these are still not sufficient.
In some cases, the article may be damaged due to friction with the guide 5. Furthermore, when articles are to be made into a single row at high speed, the length of the conveyor becomes longer, the noise becomes louder, and the bridging phenomenon is more likely to occur.

The present invention was made to eliminate the drawbacks of conventional conveyor devices of this type, and the present invention has been made to eliminate the drawbacks of conventional conveyor devices of this type.
By forming a roller conveyor in which each end of a large number of shaft rods each having a plurality of rollers rotatably connected thereto is connected in an endless manner, mutual movement of articles on the article delivery conveyor is promoted, thereby eliminating the bridging phenomenon described above. It is an object of the present invention to provide a conveyor device that can avoid this.

! 2-5 illustrate a roller conveyor suitable for use with the present invention. Reference numeral 6 designates a roller conveyor, and reference numeral 7 represents a shaft rod in which a plurality of rollers 8 are rotatably fitted, each end of which is supported by a support block 9.

Each support block 8 forms an endless roller conveyor connected by means of chains 10, 10. Cheno 1
0 and 1G engage with a drive sprocket (not shown in FIGS. 2 to 5) and are driven in a predetermined direction, and the roller conveyor 6 travels in that direction. In the present invention, the rollers 8 are fitted onto the shaft rod 7 so as to be able to slide in the axial direction, for reasons described later. It is preferable to fit it loosely. Further, the roller 8 projects upward from the support block 9.

One embodiment of the invention is shown in FIG.

Note that the same reference numerals in the figures indicate the same or equivalent parts.

According to the present invention, as shown in FIG. 6, a roller conveyor 6 as shown in FIGS. 2 to 5 is used as the article delivery conveyor 1. Note that 11 is a drive sprocket that engages with the chino 1a of the roller conveyor 8 (see Figures 2 to 5), and 12 is an electric motor that rotationally drives the drive sprocket 11. As the article receiving conveyor 2, a Cheaple Trabutien conveyor is used in which a number of plates 14 are connected and a chino 15 provided on the back side is driven by a drive sprocket (not shown).

The article sending conveyor 1 is installed so that the top of its roller 8 is approximately at the same height as the plate 14 of the article receiving conveyor 2, but the top of the roller 8 is at the same height as the top surface of the plate 14 or slightly higher. It is preferable to keep it in place in order to smoothly shift the articles to the article receiving conveyor 2 in the lateral direction. However, if the article 3 is large or has a rounded bottom edge like a beer bottle, there is practically no problem even if the top of the roller 8 is slightly lower than the top surface of the plate 14. The spacing between the article delivery conveyor 1 and the article receiving conveyor 2 is preferably as small as possible, and in the illustrated embodiment is only about the width of the support block 8 of the article delivery conveyor 1. The guide member 5 is preferably made of a material such as plastic that has low frictional resistance against the article 3, and is formed at an appropriate height depending on the shape and size of the article 3 and has an appropriate size (height dimension). Just set it up.

Next, the operation will be explained. Goods delivery conveyor 1
The article 3 that has been conveyed in the direction of the arrow 4 on the conveyor 2 is shifted laterally by the guide member 6 and transferred to the article receiving conveyor 2. At this time, as mentioned earlier, the article δ
is subjected to a lateral force by the guide member 5, but since a roller conveyor in which a plurality of rollers 8 are fitted to each shaft 7 so as to freely rotate is used as the article delivery conveyor 1, the article 3 is It can ride on different rollers 8, and each roller 8 can rotate freely, so that even when subjected to lateral forces, some parts may advance before others or fall behind, depending on the situation. You can make your own movements according to your needs. Moreover, the article delivery conveyor 1 is a roller conveyor, and the contact area with the bottom of the articles is small and the frictional resistance is also small, so that the displacement between the articles 3,
In other words, it becomes easier to give way to each other when moving forward while being shifted in the lateral direction and directing the pressing force inward. Therefore, in the conventional conveyor device, the bridging phenomenon occurred because the articles 3 were difficult to displace from each other, but according to the present invention, the articles 3 are easily displaced from each other, and the articles 3 are moved along the guide member 5 in the article flow direction. to form a single row from multiple rows without a bridging phenomenon.

Furthermore, if the rollers 8 are dimensioned so that the bottom of one component S rides on two or more adjacent rollers 8 on the same shaft 7, the adjacent rollers 8 can rotate in opposite directions. Since the article 3 can also be rotated and its orientation can be changed.

Furthermore, as mentioned above and as shown in FIG. If the total axial dimension of all the rollers 8 on the shaft 7 is made smaller than the distance, the roller 8 can move laterally by the above-mentioned amount of space while carrying the article S. Not only does this become a factor that makes the mutual displacement of the articles S easier, but also when the article 3 is transferred from the article sending conveyor 1 to the article receiving conveyor 2, if the roller 8 slides toward the article receiving conveyor 2 side, this will occur. This will facilitate the transfer of goods.

Also, the speed of the article receiving conveyor 2 is set higher than the speed of the article sending conveyor 1 (for example, 50 to 500% higher than the speed of the article sending conveyor 1, and the roller belt 6 of the article sending conveyor 1 (5),
6 (2), 6 (1), and then when the article moves to article receiving conveyor 2, 14 (5), 14 (4), 14 (3) of conveyor 2.
.

14(2) and 14(1)) The article receiving conveyor 2 takes out the articles S from the article sending conveyor 1.

Although the present invention has been described above with reference to the specific embodiment shown in the drawings, the roller conveyor is not limited to the one shown in the drawings.
Any type of conveyor, as long as it is an endless connection of a number of shafts, each of which has a plurality of rollers rotatably fitted therein, and there is nothing on the goods receiving conveyor side that prevents the goods from transferring. It can also be used. Further, the number of rollers fitted to each shaft may be any number as long as it is plural. Further, the conveyor device of the present invention can be used to convert not only bottles but also all kinds of articles from multiple rows to a single row while performing lateral shifting. Further, the goods receiving conveyor may be any conveyor as long as it can receive goods stably, and may be a flat conveyor as described above, a mesh conveyor, or a roller conveyor similar to the goods sending conveyor. . However, it goes without saying that it must not obstruct the transfer of articles from the article delivery conveyor.

As described above, according to the present invention, the article delivery conveyor is a roller conveyor in which each end of a large number of shaft rods each rotatably fitted with a plurality of rollers is connected in an endless manner. When the articles are transferred to the article receiving conveyor using the one-sided guide, the rollers can rotate freely individually, and the frictional resistance between the rollers and the bottom of the articles is small, so mutual displacement or movement of the articles is facilitated. , since it is a guide on only one side,
Friction between the articles and the guide is also reduced, which prevents damage to the articles and reduces noise.Furthermore, articles can be transferred smoothly, so the length of the conveyor from multi-row to single-row conveyor can be shortened. Various effects such as this are achieved.
