DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sorting device for sorting conveyed articles.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Application Laid-Open No. Hei 4-280711
As described in Japanese Patent Laid-Open Publication No. H10-209, the conveyed material conveyed from the upstream side of the main conveyor is caused to flow to the downstream side of the main conveyor, or to branch to a branch conveyor side obliquely connected to one side of the main conveyor. Sorting devices are known.

In this sorting apparatus, a plurality of conveying rollers constituting a conveying surface of a main conveyor are arranged side by side in a conveying direction, and a plurality of guide rollers are arranged in the midway area (branch area) of the conveying rollers in the conveying direction. The guide rollers are kept parallel to the transport rollers, so that the conveyed material flows downstream of the main conveyor, and the guide rollers are inclined to the transport rollers at one side. The conveyed object is diverted to a diverging conveyor on one side by turning toward the diverging conveyor. The guide rollers are arranged one by one in a direction intersecting with the transport direction similarly to the transport rollers, and have a length corresponding to the lateral width of the transport surface.

[0004]

However, in the conventional branching device, the guide rollers are arranged one by one in a direction intersecting the conveying direction, similarly to the conveying rollers, and correspond to the width of the conveying surface. Since the length of the guide roller is large, the size required for turning the guide roller is large. When the guide roller is turned, a large size is required between one end of the guide roller (the end that moves away from the conveyance roller) and the conveyance roller. Gaps occur. Therefore, when the transported object is small, the transported object falls into the gap, and there is a problem that the transported object cannot be smoothly transported or branched.

[0005] Further, although the conveyed material can be branched only to the branch conveyor on one side of the main conveyor, the conveyed material cannot be branched in both directions of the main conveyor. If the guide roller is rotated so as to diverge the conveyed material in both directions of the main conveyor, it is necessary to remove the conveyance roller whose length is about half. A large gap is created.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and reduces a gap generated between a guide roller and a transport roller when the guide roller rotates. It is an object of the present invention to provide a sorting device capable of reducing the number of articles to be conveyed and branching smoothly.

[0007]

A transfer roller is provided so as to be movable between the transport roller and the guide roller, and the end of the guide roller that moves away from the transport roller when the guide roller turns from a state parallel to the transport roller. By moving the end side of the transfer roller corresponding to the side so as to follow the movement of the end side of the guide roller, the transfer roller moves in the gap generated between the transport roller and the guide roller. The gap is made small, and even in the case of a small-sized conveyed product, the drop into the gap is reduced, so that the conveyed product is smoothly transported and branched.

According to a second aspect of the present invention, in the sorting apparatus according to the first aspect, the turning means rotates the guide roller about an intermediate position in the axial direction of the guide roller, and the transfer roller includes the guide roller. A pair corresponding to both end portions in the axial direction, the transfer roller supporting means includes a swing support shaft provided between the pair of transfer rollers, and the swing support shaft as a fulcrum. It has a swing base that supports each transfer roller swingably between the transport roller and the guide roller.

The guide roller pivots around an intermediate position in the axial direction, and a transfer roller has a pair corresponding to both axial ends of the guide roller, and is provided between the pair of transfer rollers. Each transfer roller can swing between the transport roller and the guide roller with the swing support shaft as a fulcrum, so that the guide roller can cope with turning in any direction.

According to a third aspect of the present invention, in the sorting apparatus according to the first or second aspect, the follow-up means biases the transfer roller toward the transport roller via the transfer roller support means. And only when the transfer roller is supported by the transfer roller supporting means corresponding to the turning position of the guide roller and follows the movement of the guide roller, the engagement between the transfer roller support means and the urging of the biasing member is prevented. And a locking member for moving the transfer roller.

The transfer roller is urged in the direction of the transport roller via the transfer roller support means by the biasing body of the follower means, and further, the transfer roller support means corresponding to the turning position of the guide roller. By moving the transfer roller through engagement with the transfer roller supporting means and against the urging of the urging member only when following the movement of the guide roller, In addition to ensuring the movement of the transfer roller in accordance with the rotation of the guide roller, the guide roller can be adapted to turn in any direction.

According to a fourth aspect of the present invention, there is provided the sorting apparatus according to any one of the first to third aspects, wherein the guide roller comprises:
A plurality of turning means are provided in a direction intersecting with the conveying direction in the conveying surface, and the turning means turns the guide roller for each row arranged in the conveying direction.

A plurality of guide rollers are arranged in a direction intersecting the transport direction in the transport plane, and the guide rollers are rotated by the turning means for each row arranged along the transport direction, whereby each guide roller is rotated. By turning the guide rollers in the row in the same direction, the branching of the conveyed article is ensured, and furthermore, the length of the guide rollers is short, and the turning size required when turning the guide rollers is reduced. The gap between the roller and the transport roller itself becomes smaller.

Two pairs (one pair) are disposed corresponding to both ends in the axial direction of 15 and are rotatable by the transfer roller supporting means 61 via support shafts 17a penetrating rotatably at the center and protruding from both ends. In addition, it is swingably supported between the transport roller 13 and the guide roller 15, and
Accordingly, the guide roller 15 is configured to swing following the turning of the guide roller 15.

As shown in FIGS. 5 to 7, the transfer roller supporting means 61 has a pair of swing bases 63 for each of the guide roller groups 15L and 15R, and these swing bases 63 are opposed to each other. A proximal end is rotatably supported by a swing support shaft 64. A substantially L-shaped bearing member 65 is provided at both ends of the upper surface of each swing base 63.
The support shaft 17a of the transfer roller 17 is mounted on these bearing members 65. The swing support shaft 64 is erected on a support base 66 attached to the horizontal connecting member 32 at an intermediate position of the guide roller 15, that is, at a position corresponding to the center of rotation,
The transfer roller 17 can swing substantially parallel to the guide roller 15 that is turned. A rod 67 is attached to an end on the tip side of each swing base 63 in a hanging manner.

The follower 62 has a plurality of locking members 68 attached to the end of each pivot link 43.

A support plate 70 is erected from the lateral connecting member 32 so as to face the side face facing the transport roller 13 side, and a spring 71 as an urging member is stretched between the support plate 70 and a rod 67. In addition, a stopper 72 that regulates the position of the rod 67 that is pulled and urged by the spring 71 is attached.

When the guide roller group 15L, 15R is at the reference position parallel to the transport roller 13, the transfer roller
When the guide roller group 15L, 15R is turned to the left turning position or the right turning position, one of the guide rollers 15 moving away from the transfer roller 13 is set in a state parallel to the feed roller 13 and the guide roller 15. Of the locking member 68 by the movement of the end side of the
The swing base 63 is swung against the bias of the spring 71 while being engaged with the spring 67, and the transfer roller 17 follows the turning of the guide roller 15. Further, when the guide roller group 15L, 15R is turned to the left turning position or the right turning position, the other end side of the guide roller 15, that is, the other turning link 43 side is moved closer to the transport roller 13; Engagement part 69 of stop body 68
Is separated from the rod 67, and the rod 67 is kept in contact with the stopper 72 by the bias of the spring 71,
That is, the transfer roller 17 is kept parallel to the transport roller 13 and the guide roller 15.

Next, the operation of the present embodiment will be described.

First, when the conveyed material carried in from the upstream side of the sorting conveyor 11 is carried out to the downstream side of the sorting conveyor 11 without branching, the guide roller groups 15L and 15R of each branching section 16 are transported by the conveying section 14. The transfer roller 17 is maintained in a state parallel to the transfer roller 13 and the guide roller 15 while being kept at the reference position parallel to the transfer roller 13.

For this reason, the conveyed articles carried in from the upstream side of the sorting conveyor 11 are conveyed by rotating conveying rollers.
The transport roller 13, the guide roller 15, and the transfer roller 17 transport the roller 13 and the guide roller 15 to the downstream side of the sorting conveyor 11.

At this time, in addition to transporting the transported article by setting the transport speed of the transported article by the transport roller 13 and the transporting speed of the transported article by the guide roller 15 to be different, since the transport roller 13 and the guide roller 15 are driven separately, The guide roller 15 can be set at a higher speed than the transfer roller 13 in order to increase the interval (conveyance pitch) between conveyed objects, or the guide roller 15 can be set at a lower speed than the transfer roller 13 to reduce the interval between conveyed items. It is possible to arbitrarily adjust the interval between the conveyed articles by controlling the speed.

When a conveyed article carried in from the upstream side of the sorting conveyor 11 is branched from the branching section 16 to the right or left branching conveyor 25, the branching section 16 is disposed on the near side in the transport direction F. When a conveyance object is detected by the detecting means (not shown), the cylinder body 47 of each guide roller group 15L, 15R is operated, and each guide roller group 15L, 15R is turned rightward or leftward, and the guide roller 15 is rotated. It is stopped at the right turning position (the position shown in FIG. 1) or the left turning position which is inclined with respect to the transport roller 13 and parallel to the right or left branch conveyor 25.

Therefore, the conveyed article transferred from the transfer roller 13 onto the guide roller 15 through the transfer roller 17 is guided by the rotationally driven guide roller 15 toward the branch conveyor 25, and is transferred from the sorting conveyor 11 to the branch conveyor 25. It is branched to the branch conveyor 25.

At this time, the guide roller 15 is divided into two parts in a direction intersecting the transport
Since the length of 15 in the axial direction is about half of the length of the transport roller 13 and is short, the turning dimension required at the time of turning the guide roller 15 is small, and the gap between the swiveled guide roller 15 and the transfer roller 13 is small. Even in the case of a small-sized conveyed product, the conveyed product is smoothly transported and branched, with a small drop into the gap.

Further, since the rotational speed of each of the guide roller groups 15L and 15R is faster on the side farther from the side closer to the branching direction, that is, in FIG. 1, the guide roller group 15L on the left side is faster than the guide roller group 15R on the right side. Then, the conveyed article is surely moved in the branching direction and is branched.

When each of the guide roller groups 15L and 15R turns, the follower 62 moves the end of the transfer roller 17 corresponding to the end of the guide roller 15 moving away from the transport roller 13 to the guide roller 15. Is moved in accordance with the movement of the end side. Thereby, the transfer roller 17 is moved to the gap generated between the transport roller 13 and the guide roller 15, and the gap is reduced, and even in the case of a small-sized transported product, the drop in the gap is small, and the transport of the transported product and Branching is performed smoothly.

In the following means 62, each transfer roller 17 is supported by a swing support shaft 64 provided between the pair of transfer rollers 17 as a fulcrum.
Is swingable between the transport roller 13 and the guide roller 15, so that the guide roller 15 can be turned in any direction.

In the follower means 62, the guide roller groups 15L, 15R
Is at a reference position parallel to the transport roller 13, the transfer roller 17 is in a state parallel to the transport roller 13 and the guide roller 15, while the guide roller group 15L, 15R is moved to the left turning position or the right turning position. When the guide roller 15 is turned, the guide roller 15 moving away from the transport roller 13 moves on one end side, that is, on the one turning link 43 side, so that the engaging portion 69 of the locking body 68 is engaged with the rod 67. The oscillating base 63 is oscillated against the bias of the spring 71, the transfer roller 17 follows the turning of the guide roller 15, and the guide rollers 15L and 15L are moved.
When R is turned to the left turning position or the right turning position, the other end side of the guide roller 15, that is, the other turning link 43
The side is moved closer to the transport roller 13, but the engaging portion 69 of the locking body 68 is separated from the rod 67, and the rod 67 is held in a state of being in contact with the stopper 72 by the bias of the spring 71, that is, Since the transfer roller 17 is kept parallel to the transport roller 13 and the guide roller 15, the transfer roller 17 can be reliably moved in accordance with the rotation of the guide roller 15, and any direction of the guide roller 15 can be used. It can also respond to turning.

It is to be noted that a large conveyed object can be surely branched by turning each guide roller group 15L, 15R in the same direction. However, since each guide roller group 15L, 15R turns independently, for example, sorting is performed. In the case where small articles are conveyed to one side or both sides of the conveyor 11,
As shown in FIG. 8, this can be achieved only by independently turning the guide roller groups 15L and 15R corresponding to the side on which the article is transferred, and furthermore, one or both of the guide roller groups 15L and 15R are separated from each other by a sorting conveyor. By turning to the center of the sorting conveyor 11, a conveyed product that is conveyed to one side of the sorting conveyor 11 can also be brought to the center of the sorting conveyor 11.

The guide roller 15 may be disposed at least partially in the width direction crossing the conveyance direction F in the conveyance surface 18 in parallel with the conveyance roller 13, or three or more in the width direction. It may be provided.

[0044]

According to the sorting apparatus of the first aspect, the transfer roller is provided so as to be movable between the transport roller and the guide roller, and when the guide roller turns from a state parallel to the transport roller, Since the end of the transfer roller corresponding to the end of the guide roller moving away from the conveyance roller follows the movement of the end of the guide roller, the end is moved between the conveyance roller and the guide roller. The transfer roller moves in the created gap, and the gap can be made smaller. Even in the case of a small-sized conveyed product, it is possible to reduce the drop into the gap and to smoothly convey and branch the conveyed product.

According to the sorting device of the second aspect, in addition to the effect of the sorting device of the first aspect, the guide roller pivots around an axial intermediate position, and the transfer roller moves in the axial direction of the guide roller. And a pair corresponding to both end sides of the transfer roller, and each transfer roller can swing between the transport roller and the guide roller with a swing support shaft provided between the pair of transfer rollers as a fulcrum. Therefore, it is possible to cope with turning the guide roller in any direction.

According to the sorting device of the third aspect, in addition to the effect of the sorting device of the first or second aspect, the transfer roller is transported via the transfer roller support means by the biasing member of the follow-up means. The locking member urges in the direction of the roller, and is further engaged with and disengaged from the transfer roller supporting means in accordance with the turning position of the guide roller. Since the transfer roller is moved through the engagement and against the urging of the urging body, the transfer roller corresponding to the rotation of the guide roller can be reliably moved, and the guide roller can be moved in any direction. It can also handle turning.

According to the sorting device of the fourth aspect, in addition to the effect of the sorting device of any one of the first to third aspects, a plurality of guide rollers are arranged in a direction intersecting the transport direction in the transport surface. Since the guide rollers are turned for each row arranged along the conveyance direction by the turning means, the conveyed article can be surely branched by turning the guide rollers of each row in the same direction, and furthermore, the guide rollers are rotated. Since the length is short, the turning dimension required for turning the guide roller is reduced, and the gap itself between the turned guide roller and the transport roller can be reduced.
