Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention belongs to the technical field of transferring or processing continuous forms. In particular, it belongs to the technical field of transferring or processing a continuous form that has been processed to increase the sliding friction coefficient when the transfer resistance is large.

[0002]

2. Description of the Related Art In the transfer of a continuous form, the frictional force of the sliding surface where the guide plate which determines the transfer path contacts the continuous form may adversely affect the transfer. For example, a guide plate (R plate) that is curved in an arc shape so as to change the transfer direction of a continuous form from vertical to horizontal and presses the continuous form has a large frictional force. FIG. 5 shows an example of a conventional continuous form processing apparatus having an R plate on a transfer path. As a countermeasure, a tape for reducing friction is attached to the sliding surface of the guide plate. An anti-friction tape is a tape that is attached to a sliding surface to reduce the frictional force of the sliding surface. In particular, when the continuous form is processed to increase the coefficient of sliding friction, for example, when a pressure-sensitive adhesive that can be sealed by pressing is applied to the continuous form, This tape for reducing friction is widely used.

[0003]

However, depending on the form of the continuous form and the contents of the processing, even if the antifriction tape is used, a sufficient effect cannot be obtained, and a problem in transporting may occur. For example, a problem arises when a continuous form folded and folded in the vertical direction so that the feed holes are exposed on the left and right sides is transported by a pin tractor by fitting pins into the feed holes. Here, the direction parallel to the continuous form transfer direction is referred to as a vertical direction or a vertical direction, and the direction perpendicular to the continuous form transfer direction is referred to as a horizontal direction or a horizontal direction. That is, the continuous form folded in the vertical direction is a so-called Z-folded continuous form (see FIG. 4A) or a multi-layered Z-folded continuous form (see FIG. 4B). As shown in FIG. 4, the continuous form is folded in such a manner that the feed holes are exposed on the left and right sides.

[0004] In such a Z-folded continuous form, one of the left and right pin tractors is provided with a guide plate (R plate).
The continuous form is transported at a feed hole provided at the end of the lower sheet in contact with the sheet. In addition, the other of the left and right pin tractors transfers a continuous form through a feed hole provided at the end of the upper sheet that does not contact the guide plate (R plate). As a result, when the frictional force between the lower sheet and the guide plate (R plate) is large, the transfer resistance is large, and the lower sheet is about to come off from the pin tractor, and is shifted from a correct position to a delayed position. It will be transported by. On the other hand, since the frictional force does not act on the other upper sheet, the sheet is transported at a correct position. Therefore, the position of the folding perforation in the horizontal direction is different between the lower sheet and the upper sheet, which causes a problem in folding and other processing at the folding perforation. In particular, this problem becomes remarkable in the case where the material is transferred at a high speed and processed.

[0013]

Next, the present invention will be described with reference to embodiments. One example of the configuration of the continuous form processing apparatus of the present invention is shown in FIG. 1 as an external view. In FIG. 1, reference numeral 1 denotes a heavy folding section, 2 denotes a sheet feeding section, 3 denotes a cutting section, and 4 denotes a crimping section. The processing apparatus shown in FIG. 1 is a processing apparatus called a mail sealer, which folds a continuous form and processes it into a mail piece with four sides sealed. The structure of the paper feeding unit (transfer device) is different from that of the conventional processing device shown in FIG. 5 (details will be described later).

The double folding section 1 is a portion where the continuous form 11 is folded in the vertical direction. The portion of the continuous form 11 that is to be folded and folded is subjected to a vertical perforation, so that the portion is easily folded. When the folding force is applied to the continuous form 11, the continuous form 11 is accurately folded at the position of the vertical perforation. The paper feeding unit 2 includes a pin tractor and a transfer roller. The pin tractor transfers the folded and folded continuous form by fitting pins into feed holes provided on the left and right sides thereof. The transfer roller is provided on a transfer path upstream of the pin tractor. The transfer roller is rotationally driven synchronously so that the speed at which the pin tractor transfers the continuous form folded and folded is equal to the speed of the peripheral surface.

Although not shown in FIG. 1, a slitter section is provided between the sheet feeding section 2 and the cutting section 3 (see FIG. 5). The continuous form folded and folded in the slitter section is cut off at the feed holes provided on the left and right sides. The part of the hole that has been cut off is housed in a box. The cutting unit 3 breaks (bursts) the continuous folded form at a horizontal perforation. The break was caused by two rollers with different rotation speeds (Fig. 5
(A front rubber roller and a rear rubber roller). This strong tension is at an appropriate timing (when the horizontal perforation reaches the position of the burst roll in FIG. 5).
It is given by pinching the continuous form folded in the above.

The crimping section 4 applies pressure to bond the continuous form at the pressure-sensitive adhesive portion of the broken continuous form. The pressure-sensitive adhesive part is an adhesive part whose adhesiveness is activated by pressure. For example, pressure-sensitive adhesive parts coated with natural rubber used in continuous forms do not activate when the pressure force is small,
When the pressing force is large, the adhesiveness is activated. The pressure bonding section 4 is configured by a pair of pressure rollers. One of the rollers is a fixed roller, and the other is an eccentric roller having a mechanism for adjusting a gap between the pair of pressure rollers. The rotation axis of the eccentric roller is supported by the rotation collar at a position eccentric from the rotation center of the rotation collar (the axis of the eccentric roller itself is not eccentric). Therefore, the gap between the pair of pressure rollers can be adjusted by rotating the rotating collar and adjusting the rotation angle (position). This structure enables a pressurization with a large force, for example, a pressurization of about 1 ton at a linear pressure. A pressure-sensitive adhesive portion where the adhesiveness is activated by such pressurization is provided in advance around a portion to be bonded in the continuous form, usually around the continuous form folded and folded. A stacker section is provided downstream of the crimping section 4. The continuous form that has been broken and sealed by bonding is accumulated in the stacker section.

Next, the sheet feeding section 2 (transfer device) will be described in detail. The transfer device of the present invention is applied to the paper feeding unit 2 of the processing device shown in FIG. FIG. 2 shows an example of the structure of the sheet feeding unit 2 in the processing apparatus of the present invention. In FIG. 2, 11
Is a continuous form, 21 is a pin tractor, 22a and 22b are transfer rollers, 23 is a timing belt, 28a and 28b are press rollers, and 29 is a slitter. The paper feed unit 2 shown in FIG. 2 has two transfer rollers having different diameters, that is, a transfer roller 22a and a transfer roller 22b. The invention is not limited in the number of transport rollers. Further, the present invention is not limited in the diameter of the transfer roller. Depending on the size of the space for installing the transfer rollers and the shape and distance of the transfer path of the continuous form, transfer rollers of an appropriate number and diameter can be installed at appropriate positions of the sheet feeding unit 2.

The transfer rollers 22a and 22b are rotationally driven, and as described above, the speed at which the pin tractor 21 transfers the continuous form 11 and the transfer rollers 22a and 22b.
It is driven to rotate synchronously so that the speed of the peripheral surface of b coincides. In the example shown in FIG. 2, to synchronize,
Timing belt 23 from drive shaft of pin tractor 21
Thus, the driving force is transmitted to the transfer rollers 22a and 22b. This configuration can be variously modified. The driving force can be obtained not from the driving shaft of the pin tractor 21 but from the driving shaft (main shaft) of the processing device. Transfer the servo motor to the transfer rollers 22a, 22
It can be used for b rotation drive and synchronized. The same applies to a case where a transmission means such as a chain or a gear is used instead of the timing belt.

The transfer rollers 22a and 22b are connected to the continuous
In the transfer path, the continuous form 11 is provided at a portion where the transfer direction is changed from a vertical direction to a horizontal direction. If this portion is a guide plate (R plate: see FIG. 5), a large frictional force is generated. Here the transfer roller 22
By providing a and 22b, it is possible to smoothly transfer a continuous form.

The transfer roller 22a,
FIG. 3 shows a state in which 22b is installed. FIG. 3A is a front view of the transfer rollers 22a and 22b, and FIG.
(B) is the figure seen from the side. As shown in FIG. 3, the transfer rollers 22a and 22b are arranged so that the continuous form 11 keeps an appropriate radius and changes the transfer direction from a vertical direction to a horizontal direction. This is because the continuous form 11 is folded in an overlapping manner, and if the radius is small and not appropriate, the continuous form 11 is damaged due to wrinkles (wrinkles) or the like. In addition, the transfer rollers 22a,
Reference numeral 22b has a lateral dimension that can correspond to a continuous form having a maximum width (maximum lateral dimension) that can be processed by the processing apparatus.

The continuous form 11 is transferred to transfer rollers 22a and 22b.
Further, a pressing roller (not shown) which can be shifted between a wearing position and a detaching position to be clamped can be provided. When this pressing roller is provided, the continuous form 11 is nipped and transferred by the pressing roller and the transfer rollers 22a and 22b, so that the adverse effect of resistance in the transfer path due to frictional force or the like can be extremely reduced. In that case, the pin tractor 21
When the peripheral speeds of the transfer rollers 22a and 22b are completely matched with the transfer speed, the tension value at the entrance of the transfer rollers 22a and 22b becomes the tension between the pin tractor 21 and the transfer rollers 22a and 22b. Also, if the peripheral surface speed of the transfer rollers 22a, 22b is slightly reduced with respect to the transfer speed of the pin tractor 21, the tension between the pin tractor 21 and the transfer rollers 22a, 22b can be increased.

In FIG. 2, the pressing rollers 28a, 28
b has the function of suppressing the continuous form 11 folded and folded to expand due to the restoring force of the fold, thereby making it flat. The continuous form 11 is folded in such a manner that the feed holes are exposed on the left and right sides. The pin tractor 21 transfers the continuous form 11 by fitting a pin into a feed hole of the folded and folded continuous form 11. The stacked and folded continuous form 11 transported by the pin tractor 21 is fed to the slitter 29, where unnecessary portions on the left and right sides of the continuous form 11 are cut off.

A form transport device is provided. According to the transfer device of the second aspect of the present invention, since the transfer roller is provided in the guide plate (R plate) in a portion where a large frictional force is generated, the effect of smoothly transferring the continuous form is particularly remarkable. . Further, according to the transfer device according to the third aspect of the present invention, the transfer can be smoothly performed in the transfer system of the folded and folded continuous form which is easily affected by the frictional force in the transfer. Further, according to the transfer device according to claim 4 of the present invention, the transfer of the continuous form is smoothly performed in the transfer system between the heavy folding section and the cutting section, which is liable to be affected by the frictional force in the transfer and causes a problem in processing.
