Embodiments of the present invention will be described below with reference to the drawings. 1, 2, 3 and 4 are a front view, a plan view, and a sectional view taken along the line III-III in FIG. 1 of a glass bottle color sorter having a cylindrical container alignment device according to an embodiment of the present invention. FIG. 4 is a sectional view taken along line IV-IV in FIG. In FIG. 1, reference numeral 1 denotes a hopper mounted on a frame 2, into which various colored gas bottles W, which are cylindrical containers, are charged. At the side of the hopper 1, the discharge end (the right end in FIGS. 1 and 2)
The belt conveyor 3, which is appropriately inclined (25 to 40 °) so as to be higher, is disposed with its carrying end facing the discharge port 4 of the hopper 1. The belt conveyor 3 conveys the glass bottle W discharged from the discharge port 4 of the hopper 1 into a single layer by sliding down due to its own weight.
The conveyor belt 5 has a single-layer glass bottle W
A number of protrusions (not shown) extending in the width direction of the conveyor belt 5 are provided at required intervals in the conveying direction of the conveyor belt 5 (to the right in FIGS. 1 and 2) to prevent the conveyor belt 5 from sliding down. Further, a pair of fall prevention plates 7 for preventing the glass bottles W from dropping from the side of the conveyor belt 5 are attached to the conveyor frame 6 at a distance slightly above the conveyor belt 5 in the width direction. It is.

Downstream of the inclined belt conveyor 3 in the transport direction, a horizontal belt conveyor 9 placed on a conveyor frame 8 is provided continuously with its carry-in end facing below the carry-out end of the belt conveyor 3. Have been. A glass bottle W is provided on the conveyor belt 10 of the horizontal belt conveyor 9.
Conveyor belt 10 in order to prevent the
A number of protrusions 11 (see FIG. 3) extending in the width direction are provided at required intervals in the conveying direction of the conveyor belt 10 (for example, at a height of 5 mm and at an interval of 75 mm), and the conveyor frame 8 of the belt conveyor 9 is provided. A pair of fall prevention plates 12 for preventing the glass bottles W from dropping from the side of the conveyor belt 10 is attached to the glass bottle W slightly above the conveyor belt 10 and separated in the width direction. Below the (almost middle in the longitudinal direction, for example a belt conveyor 9) predetermined position of the conveyor belt 10 in a horizontal belt conveyor 9, horizontal, vertical, three-dimensional motion vibrator 13 Ru to cause a slope is provided Have been. The vibrator 13 is mounted on a mounting base 17 which is mounted on a frame 15 erected on a base 14 with a plurality of springs 16 interposed therebetween. It is configured with a weight attached. A plurality (five in this embodiment) of free flat rollers 19 in contact with the carrier-side back surface of the conveyor belt 10 are provided on a roller frame 18 erected on the mounting base 17 in the width direction of the conveyor belt 10. Is extended and attached. This flat roller 1
Instead of 9, a plurality of wheels may be rotatably mounted on a plurality of shafts extending in the same direction as the extending direction.

In the vicinity of the transport end of the belt conveyor 9,
Two color detectors 20 that detect the color of the gas bottle W conveyed by the conveyor belt 10 are provided side by side. The two-color detector 20 receives a signal from the light source 21 and the CCD camera 22 which are arranged in the width direction of the conveyor belt 10 so as not to be affected by the label, and receives signals from the CC camera 22 so as not to be affected by the label. And a light source 21 and an image processing type color sensor
The arrangement of the CD camera 22 is reversed. The number of the color detectors 20 is not limited to two, and may be one. Further, downstream of the color detector 20 in the belt conveyor 9,
A sorter 24 for sorting the glass bottles W by color is additionally provided. The sorter 24 is arranged on one side (the lower side in FIG. 2) of the conveyor belt 10 and has two bottle shooters 25 attached to the conveyor frame 8, and is arranged on the other side of the conveyor belt 10 so as to face both bottle shooters 25. It comprises an air jet nozzle 26 attached to the conveyor frame 8 and a bottle shooter 27 attached to the conveyor frame 8 in close proximity to the conveyor end of the conveyor belt 10. The supply of the compressed air to both air jet nozzles 26 is performed by using an electromagnetic switching valve 30 interposed in a pipe 29 connecting the compressed air source 28 and each air jet nozzle 26,
Switching is controlled by a sequencer 31 which operates in response to a signal from the image processing type color sensor 23.

The colored glass bottle W put into the hopper 1 in the gas bottle color sorter having the above-mentioned structure is supplied from the discharge port 4 of the hopper 1 to the inclined belt conveyor 3, and the belt conveyor 3 slides down by its own weight. While being layered, it is conveyed while being prevented from falling down by the ridges and falling by the fall prevention plate 7, and is discharged onto the conveyor belt 10 of the horizontal belt conveyor 9 in a random state. Next, while the glass bottle W is being conveyed while being prevented from falling from the conveyor belt 10 by the fall prevention plate 12, the key of the conveyor belt 10 is
Carrier side and via free rollers or freewheels
The three-dimensional motion of the vibrator 13 prevents the rolling in the transport direction by the ridges 11, and is horizontally swung while being vibrated in the vertical direction, and is fitted between the adjacent ridges 11 to extend in the longitudinal direction. Are aligned in the width direction of the conveyor belt 10. The glass bottle W conveyed near the discharge end of the horizontal belt conveyor 9 is
After the color is discriminated by the color detector 20, the sorter 2 that operates according to the color upon receiving a signal from the color detector 20
The air jet from the air jet nozzle 26 is discharged from the bottle shooter 25 or the bottle shooter 27 provided at the discharge end of the belt conveyor 9 and sorted by color.

In the above-described embodiment, a case has been described in which two belt conveyors 3 and a horizontal belt conveyor 9 are used. However, the present invention is not limited to this, and includes an inclined portion and a horizontal portion. One belt conveyor may be used. The sorter 24 is not limited to the case where the air jet nozzle 26 is used, but may be one using a lever or one using an air cylinder.

[0011]

As described in the foregoing, according to the integer RetsuSo location of the cylindrical container of the present invention, in the vertical direction a cylindrical container being prevented rolling in the conveying direction by the ridge in the middle of the horizontal conveyor Since it is swung horizontally while being vibrated, it is fitted between adjacent ridges and aligned, so even if a cylindrical container is randomly supplied on a horizontal conveyor belt, its longitudinal direction is the length of the conveyor belt. It can be automatically aligned to be oriented in the width direction. In addition, the cylindrical container does not fall from the conveyor belt during the alignment and the transportation, so that the alignment and the transportation can be performed smoothly and safely.
