DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a schematic plan view of a speed difference type alignment supply device showing an embodiment according to the present invention. First, regarding the speed difference type aligning and supplying apparatus of this one embodiment, the overall image will be roughly described. A plurality of containers conveyed in parallel at random are fed from a wide supply path 1 and, for example, from the left side to the right side. First and second transfer conveyors 2 and 3 are arranged so as to gradually approach the first and second rows, and then the containers in the first and second rows are reversed from the right side to the left side in one row. 3rd step by step so that they are transported in series,
The fourth and fifth conveyors 4, 5 and 6 are provided. Further, on the first and second transfer conveyors 2 and 3, a first guide member 7 for guiding the container from the left side to the right side substantially obliquely.
Is installed. And the first and second transfer conveyors 2,
3 is provided with a conveyor divided into multiple rows. The speed of each of the conveyors is adjusted by the driving device 8 via a multistage pulley so that the speed increases as the distance from the first guide member 7 increases. This allows
By the first guide member 7 and the multi-row first and second transfer conveyors 2 and 3 having different speeds, the container gradually moves to a higher speed conveyor, so that the container moves earlier and earlier. Since it is regulated by the first guide member 7, a plurality of random containers that are sent in parallel are gradually arranged in one or two rows and transferred to the next third conveyor 4. The portion constituted by the first and second conveyors 2 and 3 and the first guide member 7 is a guide for correcting the direction of the first step, and corresponds to the first alignment portion 9 of the article introduction / breaking portion. . Next, with the same configuration, the first aligning portion 9
Each of the divided conveyors of the third transfer conveyor 4 is arranged so that the high speed side is slowed down. Further, the second guide member 10 is also installed so as to guide it from the right side to the left side in the opposite direction substantially obliquely. Third and fourth conveyors 4, 5
Is also a conveyor divided into multiple rows, the second guide member 10
The speed is changed by the driving device 8 through the multistage pulley or the like so that the speed increases as the distance from the position increases. The final fifth conveyor 6 corrects the direction of the containers so that the containers are surely arranged in a single line and is transferred. Here, in more detail, FIG.
In the above, the containers are conveyed from the right side to the left side. For example, the containers conveyed in a state of a large number of random rows are supplied to the wide supply path 1. Then, the containers fed on the divided conveyors whose speeds increase as they move away from the first guide member 7 advance forward as fast as those on the high speed conveyor, and on the low speed conveyor ( The container placed on the lower speed as it is closer to the first guide member 7 is regulated and transferred by the first guide member 7 to the faster conveyor than the conveyor. This gradually reduces the number of rows. The conveyor conveyor was divided into the first conveyor conveyor 2 and the second conveyor conveyor 3 in that the guide member was provided so as to gradually reduce the number of rows, but the width of the conveyor decreases as the number of rows decreases. In order to eliminate waste because it is no longer necessary, the number of the second conveyors 3 is reduced and the width is narrow.
3rd and 4th, depending on the quantity of the randomly sent containers
Needless to say, it may increase.

Next, the number of rows is reduced to 1 to 2
At the line, the third, fourth, and fifth transfer conveyors 4, 5, and 6 are provided stepwise by reversing as shown in the drawing. The numbers of the third, fourth and fifth conveyors 4, 5, 6 are successively reduced. Moreover, the last 5th conveyor 6 has the second
The guide member 10 is connected to the third, fourth and fifth transfer conveyors 4,
It extends diagonally across 5 and 6. Further, the respective divided conveyors, as well as the third, fourth, and fifth transfer conveyors 4, 5, and 6, gradually increase in speed as they move away from the second guide member 10, as described above. It is like this. Thus, the orientation is finally corrected to ensure that the containers are in line.
The second aligning portion 11 for performing alignment and direction correction at the same time as a portion constituted by the third, fourth, and fifth transport conveyors 4, 5, 6 and the second guide member 10 guides the second stage. Will be equivalent to. Due to the above-mentioned configuration, particularly when a deformable container or the like is conveyed, the final portion of the first alignment portion 9 as a guide for correcting the direction of the first stage causes a two-row flow like a stagnation (deformation). (They are sent in a state that the containers are biting each other.) This is transferred to the second aligning section 11 that serves as the second guide, and at the same time, the row on the side that has been sent at a slower speed, The line on the side sent at high speed and the line sent at high speed becomes slow here, so that the two-line flow that has been occurring up to now is eliminated. For this reason, it is possible to reliably carry the sheets in the one-row serial state required in the next step. That is, by the advancing force of each of the plurality of divided conveyors forming the first to fifth transfer conveyors 2, 3, 4, 5, and 6,
While being urged toward the first and second guide members 7, 10, they are accelerated as they are sequentially extruded away from the guide member of each conveyor. Then, the number of rows is gradually reduced, and in the final portion of the fifth conveyer conveyor 6, the direction is corrected in the state of one row, aligned, and transferred to the next step. In addition, the first to fifth transfer conveyors 2, 3, 4, 5,
6, a setting device for setting the number of containers to be transported per unit time, and the first to fifth transport conveyors 2, 3, 4, 5, 6
Provided with a capacity detector for detecting the number of passages per unit time of a container passing above, and inputting a detection signal from this capacity detector and a signal from the setting device to the operating speed control device,
It goes without saying that the operating speed of the drive device may be controlled by the operating speed control device so that the number of passages substantially matches the set number.

[0008]

As a result of adopting the above configuration, the present invention provides
The following effects can be obtained. (1) Reduce the flow of articles in two rows and direction abnormalities, and
And, the direction correction can be surely performed. (2) Articles, such as lightweight containers (for example, unstable containers such as PET bottles) and directional deformable containers, which are conveyed in large numbers at random, are finally conveyed in a single row to the next step. In the above, since the transfer can be performed reliably and stably, it is possible to speed up as a whole, and it is possible to cope with a higher capacity than the conventional device.
