  The present invention relates to a roller conveyor facility in which a conveying path is formed by disposing a group of rollers freely on a conveyor frame.

2. Description of the Related Art Conventionally, in this type of roller conveyor equipment, the following configuration is provided as a means for narrowing the object to be conveyed before a curve conveyance path, before barcode reading, before branch conveyance, and the like. That is, the idle roller group is supported between the pair of left and right side plates so as to be inclined at a predetermined inclination angle with respect to the conveyor width direction axis. A driving flat belt is provided that is arranged in a direction orthogonal to the rotational axis of each idler roller and contacts the surface of each idler roller. According to this, each idler roller is rotated by the movement of the flat belt, so that the article can be conveyed, and can be aligned by being aligned with one side plate side.

JP 2007-131356 A (first page, FIG. 1-3) JP-A-9-86627 JP-A-9-142623 Japanese Patent Laid-Open No. 2000-255664

  However, the conventional width-adjusting roller conveyor described above is disposed, for example, on the downstream side of the roller conveyor that conveys articles in a straight line without width-aligning, that is, for independent width-shifting in the conveyor line. The roller conveyor is incorporated and used, and therefore the cost of the conveyor line (system) may increase.

  For this, a parallel idler roller group supported in a state parallel to the conveyor width direction axis between the pair of left and right side plates and a predetermined inclination angle with respect to the conveyor width direction axis. A configuration is possible in which a group of inclined idle rollers supported in this manner is disposed, and a flat belt is disposed in a direction perpendicular to the rotational axis of the parallel idle rollers. However, in this case, the flat belt comes into contact with the surface of the inclined free-rolling roller group at a certain angle without being orthogonal to the surface, and the flat belt meanders, and the intended belt Rotational transmission cannot be performed smoothly, and further damage to the flat belt is accelerated.

  Accordingly, the invention described in claim 1 of the present invention provides a roller conveyor facility that can perform the width adjustment of the object to be conveyed without meandering the endless flat belt while being a linear conveying type using an endless flat belt. It is intended.

  In order to achieve the above-mentioned object, the roller conveyor equipment according to claim 1 of the present invention is a roller conveyor equipment in which a conveying path is formed by freely disposing a group of rollers on a conveyor frame. The group is arranged so that the roller axis is orthogonal to the conveying path, and the driving means of the roller group includes an endless flat belt that can contact the roller group from below with the belt thickness direction as the vertical direction along the conveying path. The endless flat belt is provided with a drive unit, and an inclined roller having a roller axis inclined with respect to the conveyance path is disposed at a set position in the conveyance path. A rotation transmission means is provided between the inclined roller and the endless flat belt, and the rotation transmission means is provided on the conveyor frame so as to be freely rotatable with its rotation axis being orthogonal to the conveyance path. It is composed of a passive ring body and an endless round belt wound around the passive ring body and the inclined roller, and the endless flat belt is configured to be able to contact the passive ring body from below. It is a feature.

  Therefore, according to the first aspect of the present invention, the endless flat belt rotating with the belt thickness direction as the vertical direction by the driving of the driving unit in the driving means is received from below by the receiving ring body group and pushed up. In this way, the roller group can be brought into contact with the roller group from below, and the roller group can be driven to rotate, so that the conveyance path can be brought into a driving conveyance state. In such a driving conveyance state, the endless flat belt can contact the passive wheel from below to drive and rotate the passive wheel, and the driving rotation of the passive wheel can be inclined via the endless belt. Accordingly, the inclined roller group can be driven to rotate around a roller axis inclined with respect to the conveyance path. Therefore, the object to be conveyed that has been conveyed linearly on the conveying path can be narrowed when supported and conveyed by the inclined roller group.

  In this way, at the set location, the object to be conveyed can be supported and conveyed while being narrowed. At that time, at the location other than the set location, a roller group in which the roller axis centers are arranged orthogonal to the conveyance path. Only with respect to this, the endless flat belt disposed with the belt thickness direction as the vertical direction is in contact from below, so that a constant contact force (contact pressure) can be applied to the roller group. In addition, at the set location, the endless flat belt is brought into contact with the passive ring body whose rotational axis is orthogonal to the conveyance path from below, so that the fixed ring body has a fixed shape. This can be done with contact force (contact pressure). By transmitting the rotation of the passive ring body to the inclined roller via the endless round belt, the inclination (displacement) of the inclined roller can be absorbed by the twisting action of the endless round belt.

  According to a second aspect of the present invention, in the roller conveyor facility according to the first aspect, the pair of left and right conveyor frames are provided with shaft support portions at predetermined pitches, and the roller group is arranged in the width direction of the conveyor. By positioning the roller shaft between the opposed shaft support portions, the roller shaft is supported so as to be freely rotatable between the two conveyor frames, and the inclined roller is positioned between the shaft support portions having different positions in the direction of the conveyance path. As a result, it is supported so as to be freely rotatable between the two conveyor frames.

Therefore, according to the second aspect of the present invention, the roller groups and the inclined rollers can be disposed between the two conveyor frames so as to be freely rotatable using the shaft support portions formed at predetermined pitch intervals.
In the roller conveyor facility according to claim 3 of the present invention, in the configuration according to claim 1 or 2, shaft support portions are formed at predetermined pitch intervals on the pair of left and right conveyor frames. Since the roller shaft is positioned between the shaft support portions facing each other in the direction, the roller shaft is supported so as to freely rotate between the two conveyor frames, and the rollers are separated from the two conveyor frames at a set position in the conveyance path. In addition, the roller shaft of the inclined roller is positioned between the shaft support portions having different positions in the direction of the conveyance path, so that the inclined roller is disposed so as to be freely rotatable between the two conveyor frames. It is.

  Therefore, according to the third aspect of the present invention, the position and the length of the set location can be arbitrarily set in the transport path by arranging the inclined roller at the mark where the rollers are separated from between the two conveyor frames.

  Furthermore, the roller conveyor equipment according to claim 4 of the present invention is the structure according to any one of claims 1 to 3, wherein a ring body support hole is formed at a plurality of locations of the conveyor frame. The receiving ring body group provided so as to be freely rotatable through the support hole is positioned below the adjacent rollers and pushes up the endless flat belt from below so that the endless flat belt is applied to the roller group from below. Constructed to be in contact with each other, and at the set points in the transport path, the receiving ring body is detached from the conveyor frame, and the passive ring body is arranged to be freely rotatable through the ring body support hole from which the receiving ring body is detached. It is characterized by being.

  Therefore, according to the fourth aspect of the present invention, the position and length of the set location can be arbitrarily set in the transport path by disposing the passive ring body on the trace where the receiving ring body is detached from the conveyor frame.

  According to the first aspect of the present invention described above, the endless flat belt rotating with the belt thickness direction as the up and down direction by the drive of the driving unit in the driving means is received from below by the receiving ring body group and pushed up. As a result, the roller group can be brought into contact with the roller group from below, and the roller group can be driven to rotate, so that the conveyance path can be brought into a driving conveyance state. In such a driving conveyance state, the endless flat belt abuts against the passive ring body from below to drive and rotate the passive ring body, and the driving rotation of the passive ring body is inclined via the endless round belt. Therefore, the inclined roller group can be driven and rotated around the roller axis inclined with respect to the conveyance path. Therefore, the object to be transported that has been transported linearly on the transport path can be narrowed during support transport by the inclined roller group.

  In this way, at the set location, it is possible to support and convey the object to be conveyed while narrowing, but at that time, at the location other than the set location, the roller axis is arranged in a group of rollers arranged orthogonal to the conveyance path. Only for the endless flat belt arranged with the belt thickness direction as the up and down direction from the lower side, it can be performed with a constant contact force (contact pressure) against the roller group, Therefore, the rotation of the roller group can always be performed suitably and stably without causing the endless flat belt to meander. In addition, at the set location, the endless flat belt is brought into contact with the passive ring body whose rotational axis is orthogonal to the conveyance path from below, so that the fixed ring body has a fixed shape. The contact force (contact pressure) can be used, so that the passive wheel group can always be rotated suitably and stably. Then, by transmitting the rotation of the passive ring body to the inclined roller via the endless round belt, the inclination (displacement) of the inclined roller can be absorbed by the twisting action of the endless round belt, so that the rotational force is transmitted by the rotation transmission means. Can be carried out in a suitable and stable manner without difficulty.

  In this way, while it is a linear conveyance type using an endless flat belt, by incorporating a simple rotation transmission means, the endless flat belt is not damaged by meandering, and an independent conveyor is not incorporated. The width of objects can be reduced and the cost of the conveyor line (system) can be reduced.

According to the second aspect of the present invention described above, the roller groups and the inclined rollers can be freely arranged between the two conveyor frames by using the shaft support portions formed at predetermined pitch intervals.
According to the third aspect of the present invention described above, the inclined roller can be disposed on the trace where the rollers have been separated from between the two conveyor frames, so that the position and length of the set location can be arbitrarily set in the conveyance path, After installing the roller conveyor equipment, changes on site can be easily and quickly performed.

  Furthermore, according to the fourth aspect of the present invention described above, the passive ring can be disposed on the trace where the receiving ring is detached from the conveyor frame, so that the position and length of the set location can be arbitrarily set in the conveyance path. After installing the roller conveyor equipment, changes on site can be easily and quickly performed.

The position and length of the location 3 can be arbitrarily set in the transport path 2, so that after the roller conveyor facility 1 is installed, the change at the site can be easily and quickly performed.

Hereinafter, the operation in the first embodiment will be described.
For example, after the container A supplied to the start end of the transport path 2 is transported by another carry-in means (not shown), the container A is discharged from the end of the transport path 2 to another transport means (not shown). obtain. At that time, in the roller conveyor facility 1, the driving wheel body 46 is rotated by driving the motor 44 in the driving means 31, thereby rotating the endless flat belt 32 to obtain a conveying force.

Thus, the rotation of the group of rollers 21 can always be carried out in a suitable and stable manner without causing the endless flat belt 32 to meander.

  Further, at the set point 3, the belt thickness direction t is set along the transport path 2 with the belt thickness direction t being the vertical direction with respect to the passive portion 52 of the passive ring body 51 whose rotational axis 56 is orthogonal to the transport path 2. Since the endless flat belt 32 arranged is abutted from below, it can be performed with a constant abutment force (abutment pressure) against the passive ring body 51 group. The rotation can always be performed suitably and stably. Then, the rotation of the passive wheel 51 can be transmitted to the inclined roller 25 via the endless round belt 57, so that the inclined roller 25 group is driven to rotate around the roller axis 28 inclined with respect to the conveying path 2. Can do. At this time, the inclination (displacement) of the inclined roller 25 can be absorbed by the twisting action of the endless round belt 57, and therefore, the transmission of the rotational force by the rotational transmission means 50 can be carried out properly and stably without difficulty.

Thus, although it is a linear conveyance type using the endless flat belt 32, the simple rotation transmission means 50 is incorporated, so that the endless flat belt 32 is not damaged by meandering and an independent conveyor is not incorporated. The container A can be narrowed and the cost of the conveyor line (system) can be reduced.
