[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary conveyor used for an article transfer device such as a counting and feeding device for counting a predetermined number of articles sequentially conveyed and supplying the predetermined quantity, and in particular, sanitary napkins and the like. The present invention relates to a rotary conveyor for transporting a flexible article to a predetermined position.

[0002]

2. Description of the Related Art In a conventional rotary conveyor of this type, as shown in FIG. 6, a rotary belt 50 is wound around four pulleys 51, 52, 53 and 54 to supply a sanitary napkin 2. Pulley 51 at position f and discharge position g
The pulleys 52 on the front side are drive pulleys driven by motors, respectively. The pulley 52 for tension is driven by a cylinder 55, and the pulley 54 for tension is driven by a cylinder 5.
At 6, each is movable. When the sanitary napkin 2 is discharged at the discharge position g, the driving of the driving pulley 53 is stopped, whereby the tension of the rotary belt 50 between the driving pulley 53 and the entrance side driving pulley 51 is loosened. as indicated by the two-dot chain line, the pulley 52 is moved by the cylinder 55 for tensioning the holding, the driving movement of the rotating belt 50 in a relatively discharge position g is stopped, the sanitary napkin 2 in the discharge position g therebetween Discharging. A similar technique is disclosed in Japanese Patent Application Laid-Open No. 2-43132.

Further, in the conventional rotary conveyor shown in FIG. 7, two motors 61, 62 drive the rotary driving members 58, 59 via a driving belt 57, whereby a tension pulley is provided. 52 and 53 are driven. Then, the driving of one of the motors 62 is stopped, whereby the tension pulley 52,
By adjusting the tension of the drive belt 57 loosened between the drive belt 53 and
The rotary driving bodies 58 and 59 are moved to the positions indicated by two-dot chain lines, and the tension pulleys 52 and 53 are horizontally moved as indicated by broken lines in the drawing. The tension pulleys 52, 53 are rotationally driven by rotary driving bodies 58, 59 which are rotationally driven by a driving belt 57, and their positions are horizontally moved together with the rotary driving bodies 58, 58. It has become.

[0004]

However, in the former prior art shown in FIG. 6, the pulleys 52 and 54 are moved by separate cylinders 55 and 56, respectively, to adjust the tension of the rotating belt. It is difficult to adjust the timing such as stopping the driving pulley 53 on the discharge side, adjusting the driving timing, and stopping the driving of the driving pulley 51 (for example, stopping when the tooth is pulled out when no articles are loaded). Is getting worse. For this reason, the conventional rotating conveyor has a problem that vibrations and dubbing are generated in the rotating belt 50, and as a result, the counting process of articles cannot be performed reliably and at high speed.

In the latter prior art shown in FIG. 7, when the tension drive pulley 52 on the discharge position is moved to adjust the tension of the rotary belt 50, the contact of the rotary belt with the pulley 51 on the supply position is caused. The angle changes by a.
At this time, since the pulley 51 on the supply position side is not a drive pulley, the moving speed of the rotary belt 50 on the supply position side changes, and the timing of the input of the articles is deteriorated. Therefore, also in this prior art, there is a problem that the counting process of articles cannot be performed reliably and at high speed as in the former prior art.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rotating conveyor capable of reliably and quickly counting articles.

[0007]

According to the present invention, there is provided a rotating belt which conveys an article supplied at a supply position to a discharging position and discharges the article at the discharging position, and a first rotating body which drives the rotating belt. A first motor for rotating the first rotating body at a constant rotation speed ; a second rotating body and a first motor ;
3 while supporting the second rotating body and the third rotating body.
Along the linear orbit of the rotating belt connecting the rotating
An oscillating frame movably disposed on the second frame;
A second motor for driving the rotating body, wherein the rotating belt is stretched over the first rotating body, the second rotating body, and the third rotating body, and is fixedly conveyed by the first rotating body. Speed, and controls the driving of the second motor,
The peripheral speed of the second rotating body is relatively changed with respect to a constant transport speed of the rotating belt driven by the first rotating body , so that the second rotating body and the third rotating body are rotated. The above object has been achieved by providing a rotating conveyor characterized in that the swing frame is moved back and forth with respect to the traveling direction of the rotating belt together with the rotating body.

[0008]

The rotating belt is driven by the driving of the first rotating body by the first motor, and rotates by passing through the second rotating body and the third rotating body. Then, the articles are sequentially supplied to the rotating belt at the supply position, and the articles are conveyed to the discharge position where they are discharged.

When the article is conveyed, the driving of the second motor is controlled to rotate the second rotating body at the same speed as the peripheral speed of the first rotating body. When discharging the article, the peripheral speed of the second rotating body is rotated at a lower peripheral speed than the peripheral speed of the first rotating body. Thus, the second rotating body slides with the frame in accordance with the tension of the rotating belt. At this time, the speed of the rotating belt is reduced or stopped at the discharge position, and the articles are discharged during this time.

After discharging the article, the second motor is controlled to rotate the peripheral speed of the second rotating body at a higher speed than the peripheral speed of the first rotating body. Thereby, the tension on the first rotating body side is increased and the tension on the third rotating body side is relaxed, so that the second rotating body and the third rotating body are moved together with the swing frame together with the third rotating body side. And transports the articles by the rotating belt.

[0011] Such an operation is repeated, and the articles supplied at the supply position are simultaneously and continuously discharged several by one at the discharge position.

3 is formed by a rear wall portion 33a located on the rotating belt side (back side) of the pocket 12 and a front wall portion 33b located on the open side (front side) opposite to the back side of the pocket. The wall portion 33b is formed to be shorter than the rear wall portion 33a, and the rear wall portion 33a has substantially the same size as the height of the sanitary napkin 2. Since the rear wall portion 33a is formed longer as described above, when the sanitary napkin 2 is slid on the mounting table 34, the entire back side of the sanitary napkin 2 is pressed substantially evenly, and the soft napkin 2 is softened. The sanitary napkin 2 having the property can be moved smoothly. Further, since the front wall portion 33b is formed in a relatively short dimension,
When the concave body 33 engages with the sanitary napkin 2, there is no adverse effect such as pressing against the blade 11a forming the pocket 12.

The rotating body 36 is driven via a timing belt 40 by a driving wheel 41 driven in response to a control signal from a control device (not shown). The drive shaft 36a of the rotating body is provided with the drive shaft 36a.
One end portion 37a of the first link 37 is connected to two pivoting. The other end 37b of the first link 37 is connected to a corner (a substantially central portion of the L-shape) 38a of the L-shaped link 38.

One end 38b of the L-shaped link 38 is pivotally mounted on the slider 32, and the other end 38c of the L-shaped link 38 is a second end 38a on which one end 39a is rotatably supported. The other end 39b of the link 39 is pivotally supported. Next, the operation of the above-described article discharging device C will be described. In the initial state of the discharging operation, the pusher 35 is waiting above the rotating belt 11 as shown by a two-dot chain line in FIG.

When the counting detectors 42a and 42b of the sanitary napkin 2 at the discharge position g have counted a predetermined number, the driving body 41 rotates the rotating body 36 by the predetermined amount. Then, the first link 37 rotates in the direction of the arrow h around the one end 37a, and the corner 3 of the L-shaped link 38
8a is rotated downward. As a result, the slider 32 is pushed down, and as shown by the solid line in FIG.
Pivots downward, and the slider 32 slides toward the tip of the rod 31. Overall, the pusher 35
As shown by an arrow k, it moves downward so as to draw a substantially circular arc and engages so as to cover the upper end of the sanitary napkin 2 at the discharge position g.

Further, when the rotating body 36 rotates, the rod 3
1 is pushed down by a link 37 and pivots downward as it is, and a slider 32 is moved through an L-shaped link 38.
To the proximal end side of the rod 31. Therefore, the pusher 35 engages only with the upper end of the sanitary napkin 2 and pivots downward from that position, so that the pusher 35 pushes the sanitary napkin into the pocket 12 without pressing against the blade 11a. to Eject smoothly from. In addition, since the sanitary napkin 2 is taken out by the rotating operation of the pusher 35, the soft sanitary napkin can be easily taken out without suddenly popping out or deforming. Further, the front wall portion 33b reliably prevents the sanitary napkin 2 from suddenly jumping out.

Thereafter, the sanitary napkin 2 is placed in the pocket 12.
At the same time as being taken out of the sanitary napkin 2, the concave body 33 covers the sanitary napkin 2 so that the rear wall 33a of the concave body 33 covers substantially the entire back side of the sanitary napkin 2. Furthermore, the first link 3
7 rotates, as shown in FIG.
And slide the slider 32 toward the proximal end of the rod 31. At this time, the rear wall portion 33 of the pusher 35
5a moves on the mounting table 34 linearly along the direction of arrow m in FIG. 5 so as to push the entire back side of the sanitary napkin 2, and is conveyed to the next step, for example, the packaging step. In this way, by pushing and sliding the entire back side, the soft sanitary napkin 2 is not deformed and does not disturb the alignment at the time of ejection.

After the sanitary napkin 2 is transported, the rotating body 36 further rotates to rotate the rod 31 upward, and the pusher 35 escapes above the sanitary napkin 2, and at the same time, the slider 32 is moved to the rod 31. And return to the initial position shown by the two-dot chain line in FIG. According to the article discharging device C, a compressible soft article can be discharged reliably and at high speed.

As apparent from the above description, according to the counting and feeding device 1 according to the present invention, the sanitary napkin 2 supplied from the article supplying device A is supplied to the supplying position f reliably and at high speed. . Then, on the rotating conveyor B, at the supply position f, the first rotating body 13 reliably drives the rotating belt 11 at a constant speed, and conveys the sanitary napkin 2 supplied to the pocket to the discharge position g. The sanitary napkin 2 at the discharge position g is moved by the pusher 35 in a curvilinear motion from above by the article discharging device C, and then moves linearly on the mounting table to move the sanitary napkin 2 straight. 2 is discharged from the discharge position, and the sanitary napkin 2 is transported to the next step.

The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the spirit of the present invention. For example, the rotating belt 11 includes a first rotating body 13.
