For example, there is a form alignment mechanism disclosed in Japanese Patent Laid-Open No. Sho 62-180844. This mechanism, as shown in FIG.
Reference side guide G having a surface perpendicular to the carrying surface
And the form feed belt B arranged at an angle on the reference side guide G, and the friction force necessary for form feed between the back face of the form and the front face of the feed belt arranged on the surface of the feed belt B. It is composed of a rotating body R for generating.

Then, the reference side belt is moved at a speed faster than that of the feed belt, thereby giving a rotational moment to the form, and the reference side belt and the side edge of the form are aligned to adjust the posture of the form.

[0004]

In the above-mentioned prior art, since the counterclockwise rotation moment acts on the form as shown in FIG. The posture of the form can be adjusted.

However, since the rotating moment M2 as shown in FIG. 8 acts on the form P skewed in the opposite direction, the form P is pressed against the reference side belt at the point A. The state of the form is not changed, and the skew is increased.

As described above, the conventional aligning device is effective for the skew in a certain direction on the form, but has the problem that the skew in the opposite direction cannot be aligned. For this reason, there is a problem in that processing cannot be performed by a device subsequent to the alignment device, and the processing efficiency of the entire device is significantly reduced.

The present invention solves the above-mentioned problems and can accurately position a conveyed object such as an article or a paper sheet in any posture. A orienting device is provided.

As a result, a rotational moment is applied to the conveyed product such as the article or the paper sheet, and the conveyed product is rotated so that the guiding means can align the conveyed product. Therefore, it is possible to correct the posture of the conveyed object in any posture.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a first embodiment of the device according to the invention. In this embodiment, conveyor means 1 in the form of a belt conveyor that stacks and conveys articles and paper sheets (hereinafter referred to as conveyed goods), drive sources 2a and 2b and timing belt 2c for driving the conveyor means 1 2d, timing pulleys 2e, 2f, etc.
And a guide means 4 for adjusting the posture of the conveyed product 3.

As shown in the figure, the conveyor means 1 in the form of a belt conveyor for stacking and conveying the conveyed objects 3 are provided in two rows, and are driven by different driving sources. That is,
The conveying means 1a includes a drive belt 2c, a timing belt 2c
It is driven via the drive shaft 2g. Also, the transport means 1b
Is driven from the drive source 2b through the timing belt 2d and the drive shaft 2h.

Conveying means 1a, drive shaft 2h, conveying means 1b
Since the bearings 7 are mounted between the drive shaft 2g and the drive shaft 2g, they can be driven independently. The surface 1 of the conveying means 1 on which the conveyed object 3 is loaded is smooth enough to allow the conveyed object 3 to rotate on the surface.

The conveyor means 1a and 1b in the form of belt conveyors arranged in two rows as described above are respectively different drive sources 2a and 2b.
It is driven at the transport speeds Va and Vb from b. However, the transport speed Va of the transport means 1a closer to the guide means 4 is set to be higher than the transport speed Vb of the other transport means 1b. The speed can be set by changing the rotational speeds of the drive sources 2a and 2b, changing the tooth ratio of the pulleys 2e and 2f, and changing the diameter of the pulley on which the belt conveyor is hung. May be used. In this example,
The method of changing the tooth number ratio of the pulleys 2e and 2f is used.

The guide means 4 in the form of a guide has an angle θ with respect to the conveying direction of the conveyed article 3 in order to bring the conveyed article 3 into contact with a surface perpendicular to the conveying surface of the conveying means 1 and adjust its posture. It is arranged.

The contact surface 4 of the guide means 4 with the conveyed article 3
It is necessary that a is so smooth that the frictional force at the time of contact with the conveyed product 3 does not have an adverse effect such as the retention of the article 3. Therefore, in the present invention, the contact surface 4a of the guide means 4 with the article 3 is coated with a fluororesin. Alternatively, the guide means 4 may be a metal material having a smooth contact surface. The most desirable metal material is a stainless steel member.

Next, the operation of the above-described first embodiment of the apparatus of the present invention will be described with reference to FIG.

It is assumed that the conveyed state of the conveyed object 3 before alignment is conveyed at a skew angle φ as shown in the figure. When the transported object 3 is loaded on the transporting means 1a, 1b of the orienting device, the transporting speed Va of the transporting means 1a is higher than the transporting speed Vb of the transporting means 1b, so that the transportable object 3 has a rotation moment. Acts and rotates like arrow O. At this time, the transport speeds Va and Vb are set to values such that the transported object 3 does not rotate too much.

The transported object 3 is further rotated as it is transported, and this rotation causes the transported object 3 to contact the guide means 4 from the rear portion S of the side surface. After that, a rotation moment m centering on the side surface rear portion S which is in contact with the guide means 4 acts on the conveyed object 3 to rotate as shown by an arrow P, with the contact surface of the guide means 4 as a reference. The posture is adjusted.

Even if the conveyed state of the conveyed object 3 before alignment is conveyed at a skew angle opposite to the above-mentioned skew angle φ, the guide means 4 is located on the side surface of the conveying path, and therefore, the guide means 4 is also present. The article 3 is brought into contact with the guide means 4 from the rear portion S of the side surface thereof. After that, as in the case described above, the rotational moment m acts on the conveyed object 3 around the side surface rear portion S in contact with the guide means 4, and the posture is set with reference to the contact surface of the guide means 4. Is arranged.

In the above-described embodiment of the present invention, the belt conveyor-like conveying means is used as the conveying means, but a roller conveyor-like conveying means may be used. Transport means is low
Even if it is a conveyor type, the function of orientation is exactly the same as that shown in FIG.

FIG. 3 shows a second embodiment of the device of the present invention. In this figure, the same reference numerals as in FIG. 1 designate the same or corresponding parts. In this embodiment, in the case of the embodiment shown in FIG. 1, when the transporting means having different transporting speeds such as the transporting means 1 have the same length, when delivering the transported article to the next step of the alignment apparatus, Since it is possible that skew will occur again on the transported object, either one of the transportation means is provided in only a part of the aligning device, and the transported object is transported to the state necessary for the alignment while this part is transported. It is configured to rotate an object, and is configured by using a roller-shaped carrier means 1a and a belt conveyor-shaped carrier means 1b.

Also in this embodiment, since the bearing 7 is attached between the conveyor means 1b in the form of a belt conveyor and the drive shaft 2g, the conveyor means 1a and 1b can be driven independently. The conveying means 1b is not limited to the belt-conveyor-like conveying means as shown in FIG.
It may be a conveyer-shaped conveying means.

Next, the operation of the second embodiment of the above-mentioned device of the present invention will be described with reference to FIG.

The object to be conveyed 3 is the conveying means 1a, 1b of the alignment device.
When it is loaded on the article 3, since the carrying speed Va of the carrying means 1a is higher than the carrying speed Vb of the carrying means 1b, a rotational moment acts on the article 3 to rotate as indicated by an arrow O. At this time, the transport speeds Va and Vb are set to values such that the transported object does not rotate too much. The difference from the embodiment of FIG. 1 is that when the conveyed product 3 passes over the conveying means 1a, 1b of the orienting device, the conveyed product 3 does not rotate and is conveyed in its original posture. By the rotation generated on the conveying means 1a, 1b,
The article 3 is brought into contact with the guide means 4 from the rear portion S of the side surface thereof.

After that, the rotating moment m centering on the side surface rear portion S which is in contact with the guide means 4 acts on the conveyed object 3 to rotate as shown by an arrow P, and the contact surface of the guide means 4 is moved. The posture is adjusted based on the standard.

FIG. 5 shows a third embodiment of the device of the present invention. In this figure, the same reference numerals as in FIG. 1 designate the same or corresponding parts. In this embodiment, a belt-shaped conveying means 5 for holding and conveying paper sheets, drive sources 2a, 2b for driving the conveying means 5, timing belts 2c, 2d, timing pulleys 2e, 2f, etc. It is composed of a driving means 2 composed of and a guide-like guiding means 4 for adjusting the posture of the paper sheet 6.

As shown in the drawing, the belt-shaped transporting means 5 for sandwiching and transporting the paper sheets 6 are provided in two rows, and are driven by different drive sources. That is, the conveying means 5a includes the drive belt 2c, the timing belt 2c, and the drive shaft 2a.
The transport means 5b is driven from the drive source 2b via the timing belt 2d and the drive shaft 2h. Since the bearings 7 are mounted between the conveying means 5a and the drive shaft 2h and between the conveying means 5b and the drive shaft 2g, they can be driven independently.

Belt-shaped conveying means 5 arranged in two rows
a and 5b are different drive sources 2a and 2b as described above.
It is driven at the transport speeds Va and Vb from b. However, the transport speed Va of the transport means 5a closer to the guide means 4 is set to be higher than the transport speed Vb of the other transport means 5b. The speed can be set by changing the rotation speed of the drive sources 2a and 2b, changing the tooth number ratio of the pulleys 2e and 2f, and changing the diameter of the pulley on which the belt is worn. You may use. In the present invention, the pulley 2e,
The method of changing the tooth number ratio of 2f is used.

The surface of the conveying means 5 that holds the paper sheet 6 is smooth enough to rotate the paper sheet 6 on the surface.

The pair of drive shafts 2g and 2h are arranged so as to be displaced in the carrying direction so that paper sheets having a certain thickness can be carried. The amount of this shift is determined by the thickness of the paper sheet to be conveyed.

The guide means 4 in the form of a guide has a certain angle θ with respect to the conveying direction of the paper sheet 6 in order to bring the paper sheet 6 into contact with the surface perpendicular to the conveying surface of the conveying means 5 to adjust the posture. It is arranged. The contact surface 4a of the guide means 4 with the paper sheet 6 needs to be smooth to the extent that the frictional force at the time of contact does not have an adverse effect such as the retention of the paper sheet 6. Therefore, in the present invention, the contact surface 4a of the guiding means 4 with the paper sheet 6 is coated with a fluororesin. Alternatively, the guide means 4 may be a metal material having a smooth contact surface 4a. The most desirable metal material is a stainless steel member.

In this embodiment, the belt-shaped conveying means is used as the conveying means, but this may be a roller-shaped conveying means. Even if the conveying means is roller-shaped, the function of alignment is exactly the same as that shown in FIG.

In the case of the third embodiment of the apparatus of the present invention described above, the operation is exactly the same as that of the embodiment shown in FIG.

If the conveying means 5 having different conveying speeds have the same length as in the embodiment shown in FIG. 5, the paper sheets are transferred to the next step of the aligning apparatus as in the embodiment shown in FIG. It is possible that the skew will occur again when handing over. Therefore, as in the fourth embodiment of the apparatus of the present invention shown in FIG. 6, either one of the conveying means is provided only in a part of the aligning device so that the transported object is aligned while being transported through this part. You may rotate a conveyed product to a required state. The embodiment shown in FIG.
It shows an embodiment using a la-shaped conveying means 5a and a belt-shaped conveying means 5b.

Also in this embodiment, since the bearing 7 is mounted between the belt-shaped conveying means 5b and the drive shaft 2g, the conveying means 5a and 5b can be independently driven. The transport means 5b is not limited to the belt-shaped transport means as shown in FIG. 6, but may be a roller-shaped transport means.

As a method of preventing the skew generated when the paper sheets are transferred to the next step, in addition to the embodiment shown in FIG. 6, the conveying means 5a, 5b of the aligning device shown in FIG. 5 are used. It may be considered that the conveying means which are in contact with each other are not brought into contact with each other so that there is no conveying force at either outlet.

In the embodiment shown in FIG. 5 and FIG. 6, the conveying means for the paper sheets is the one which is in contact with each other, but the conveying means is not limited to the one which is in contact with each other, and the present invention shown in FIG. As in the fifth embodiment of the apparatus, the upper and lower conveying means for holding the paper sheets may be arranged so as to be displaced in the axial direction. By arranging the conveying means in this way, it is possible to convey paper sheets having a certain thickness.
