Abstract

PURPOSE:To align fruit in the uniform attitude according to the shape of a transported article and to supply same at spaces more than fixed by making the speed of feeding a transported article of a lower side rotating roll and an endless belt higher than that of an upper side endless belt in the transfer direction. CONSTITUTION:Guide surfaces 2 of large-diameter portions 8 disposed left and right alternately on an endless belt 3 portion are adapted to align the fruits 1 with the longitudinal direction thereof along the transfer direction (b). A rotating roll 5 is adapted to receive the fruit 1 fed from the transfer terminal end portion at the outer surface of a brush bristle 21 and deliver same to an endless belt 4. At this time, the rotating roll 5 and the endless belt 4 are adapted to transfer fruit at higher speed than the endless belt 3, so that the fruit is transferred onto the endless belt 4 with the individual intervals expanded. The attitude of the fruit on the endless belt 4 is corrected by the interval (a) between guide surfaces 8, 8 narrower than that in the endless belt 3 portion and the alignment of the fruits is adjusted to transfer the fruit.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sorting conveyor for fruits, etc., which arranges conveyed objects such as fruits while transporting them, and is used for sorting devices, packaging devices, marking devices, etc. for fruits, confectionery, etc. It can be used as an alignment conveyor.

Problems to be solved by the invention For example, while the fruit is being transported, its length, width, height, projected area, etc., and shape are measured, and the fruit is transported based on the measurements. In a device that automatically feeds fruit to the conveyor of a fruit sorter, which picks out fruit by size by overturning the fruit receiver of the conveyor to the side in the transport direction, the fruit is placed in a fixed posture according to the shape of each type of fruit. It is necessary to line up the fruits before and after transporting them, and to supply them with at least a certain distance between them so that the optical sensor can determine that they are separate fruits.

Means for Solving the Problem This invention has a guide surface (2) (2) that guides the transported object (1) while rotating along both left and right sides, and has a guide surface (2) (2) on which the transported object (1) is placed. One end band (3) and (4) before and after transfer
between the rotating row/
I/(5), and an endless belt (3) on the upper side in the transport direction.
), the rotating row/I/(5) on the lower side and the conveyed object (1) of the endless belt (4) are made to have a faster feeding speed to form an alignment conveyor for fruits and the like.

Functions and Effects of the Invention When the conveyed object (1) is continuously placed on the upper endless belt (3) and transferred, the guide surface (2) rotates along the left and right sides of the endless belt (3). ) (2) rotates the conveyed object (1) that bulges on both the left and right sides of the endless belt (3)
3) Guide the long conveyed object (1) within the width of the guide surface (2).
) The longitudinal direction is aligned with the transport direction by a combined effect of the feeding guide action in the rotational direction (2) and the guide action pushing the bulge toward the center of the width of the endless band (3).

When the conveyed object (1) is transferred from the transfer terminal end of the endless belt (3) onto the rotating roll /I/ (5), the rotating roll (5) adjusts the speed in the tangential direction of the rotating outer circumferential surface to the endless belt. (3) By setting the feed speed appropriately faster than the feeding speed of the conveyed object (1), the following conveyed objects are aligned and transferred on the endless belt (3) due to the frictional force with the lower surface of the conveyed object (1). It is delivered and conveyed onto the endless belt (4) on the lower side at a speed faster than the feed speed in (1).

The endless belt (4) also conveys the entire transported object (1) at a faster speed than the rotating low tv (5) and the endless belt (3) on the upper side, and the rotating low tv (5) and the endless belt ( 4) and no l' □ on the upper side, 3) □! □* (1)di
1. Even if they are in an overlapping state, break this state, increase the distance between the front and rear conveyed objects (1) (1), and transport them on the endless belt (4). At the same time, the endless belt (
4) A conveyed object whose posture has been disturbed by vibrations during transfer by the rotary rolls (5) or rolling when the overlapping state is broken, etc. of the guide surfaces (2) (2) on both the left and right sides of (2) Even if there are objects, they are guided and corrected to the aligned state.By using the alignment conveyor with this configuration, the objects (1) to be conveyed that are placed on the conveyor in close contact or in a stacked state can be corrected. Even if there is a problem, it is possible to transfer the objects in an aligned state with their postures aligned and maintaining the distance between the front and rear.

Embodiment In the illustrated example, the conveyed object (1) is a fruit, and a conveyor for arranging fruits to be fed to a fruit sorting machine (6) is illustrated. 7), the left and right sides are formed into large diameter parts (8) (8). The large diameter part (8) of Q(1αη...)
(8) The left and right facing inclined conical slopes are the guide surfaces (2)
(2). This drum-shaped guide roll (9) Q
One of the left and right large diameter portions (8 bars 8) of O(lη... The intervals (A) are formed from wide to narrow in order, and the endless bands (3
) and (4) in the direction of transfer (b) the distance between the lower and lower ends)
The space is narrow. In addition, each guide row/LI (
9) αOC1,) ...... is brought into contact with the lower surface of the endless belt (3) (4) so that the central cylindrical part (7) serves as a receiving path for the outward transfer of the endless belt (3) (4). , the small diameter portion (2)
are arranged in a staggered manner.

The endless belt (3) has a large diameter on the transfer starting end side! J-03 and
A belt conveyor is wound between the small-diameter pulley α on the terminal end side and has a width close to the size of the fruit. A guide plate (G) αG inclined in a V-shape is provided, and a chute αQ for feeding fruit from the upper side of the conveyor is provided to form a hopper shape with the endless band (3) surface as the bottom surface. The motor Q' is interlocked with the large diameter pulley (toward) on the transfer starting end side.

The endless belt (4) is connected to a large diameter pulley (g) at the upper end of the transport adjacent to the rotating roll (5) which is interposed in a space between the endless belt (3) at the upper end of the transport and the small diameter pulley α on the terminal end. The small diameter pulley αl is wound on the conveyor between the small diameter pulley αl and the small diameter pulley αl on the side. The j-Q groaning section is provided so as to approach the upper surface of the fruit receiver (1) of the conveyor of the sorting machine (6) from above and overlap with it.

The endless belt (4), like the endless belt (3), is provided with a width close to the size of the fruit.

Rotating RO/L/(5) is a brush roll with brush bristles provided on the rotating outer periphery, and is horizontally pivoted (2) between the front and rear endless bands (3) and (4). Endless band (4), rotating roll (5), and continuous drum-shaped guide row tv (9) α0 (
11) . . . are appropriately interlocked from the prime mover wire.

The sorting machine (6) has a fruit receptacle (1) having a rectangular planar shape placed on an endless chain (c) wound between both sprockets (c) at the start and end of the transfer, with the longitudinal direction facing sideways. It is arranged in a row along the endless chain (C), and can maintain the fruit-receiving posture, and can also fall to the side due to measurement by a measuring device, etc. that measures the size while transferring the fruit. It is composed of

When the fruit is fed from the chute αQ on the upper side of the transport to the transport start end of the endless belt (3), it is guided by the left and right guide plates αl19 (towards) and pulled out in a line by a belt with a width similar to the size of the fruit. The fruits that are being harvested are not in a good position, and some of them are piled up and overlapping vertically and horizontally, creating an endless belt (3)
transported on top.

Left and right guide surfaces (2) provided on the endless band (3) (2
) having guide rolls (9) αQαυ... The guide surfaces (2) of the large diameter portions (8) located alternately on the left and right sides of the row shift and bulge to the left and right of the endless band (3). The bulging part of the fruit,
While rotating, the endless belt (
3) The fruits are guided to the center in the width direction and aligned so that the longitudinal direction of the fruit bodies, which had been oriented horizontally, is aligned along the transport direction (b), but the stacking state is not broken. The rotating row /I/ (5) having brush bristles Q]) receives the fruit sent from the transfer end of the endless band (3) on the outer surface of the brush bristles (C) and delivers it to the endless band (4) on the lower side. However, the stacked state of the fruits is likely to be disrupted by vibrations, etc. at this time, and the rotating rolls and endless belt (4) transport the fruits faster than the endless belt (3), so that each fruit that is transported is separated from the fruit that follows. When it is pulled apart, the distance between the sides of the fruit body is widened, and the fruit body is placed on the endless band (4).
The posture of the fruit on the endless belt (4) is corrected by the interval (a) of the right guide surface (8) (8), and the alignment is adjusted to the small diameter day at the end of the transfer! It is transferred from the J-DI section to the upper surface of the fruit receiver of the sorting machine (6) with a small head.

In this way, even if the objects to be transported (1) are piled up, it is not only possible to break the stack and arrange the objects in an aligned manner, but also to arrange and transport the objects (1) with an appropriate distance between the front and back. So it's good.

Note that the guide surface (2) (2) may be constructed of a pair of left and right conveyor conveyor surfaces that are inclined in an upside-down shape.

Furthermore, the rotating outer peripheral surface of the rotating roll (5) may be formed of an elastic body such as rubber or synthetic resin.
