Description

[Detailed description of the invention] Industrial application field This invention is a continuous form that is placed upstream of a post-processing device that performs processing such as cutting and sorting while transporting a continuous form made up of a series of unit forms. The present invention relates to a form feeding device.

BACKGROUND ART In this type of continuous form paper feeding device, in order to stack unit forms in a predetermined order after processing in a post-processing device, it is required to adjust the orientation of the front and back sides, and the printer etc. In order to coordinate the processing speed with other equipment, it is required that the continuous form be formed into a loop so that it can be temporarily stored.

Conventionally, the direction of the front and back sides of a continuous form can be adjusted by cutting it into unit forms and then reversing the transport direction using multiple rolls, or changing the direction by passing the continuous form through a turn bar during transport. It is converted and reversed (see Utility Model Publication No. 61-21719). Furthermore, regarding the formation of continuous foam loops, an independent buffer section is provided between the other devices, and the process is carried out in this buffer section (Japanese Patent Application Laid-Open No. 59-1999).
(See No. 67070).

Problems that the invention aims to solve: The conventional structure in which the unit form is cut and then turned over has the disadvantage that it is complicated and may cause a jam when turned over, and also has the disadvantage of forming a loop at the buffer part. This configuration has the disadvantage of increasing the size of the device. Also,
When a turn bar is used in a continuous form paper feeding device, although there is no particular drawback to the structure of the turn bar itself, a buffer section must be provided when combining it with other devices such as a printer, so the existence of a buffer section is a problem. This results in the same disadvantages as mentioned above.

It is an object of the present invention to provide a continuous form paper feeding device that eliminates these drawbacks.

Means for Solving the Problems In order to achieve this object, the present invention is arranged at the front stage of a continuous foam post-processing device, and is designed to handle continuous foam that is transported from a predetermined direction through a loading port, which is a loading space. a turn bar for guiding the continuous foam in order to convert the transfer direction by 90 degrees to the horizontal direction, for example, and a loop forming space in which the continuous foam transferred via the turn bar is looped in a loop forming space located below the turn bar; a form feeding device comprising, for example, a feeding roll and a feeding roller connected to a rotational drive source, for guiding the continuous foam toward the turn bar so as to form a continuous foam; In order to send the continuous foam that is transferred after forming a loop in the process to the post-processing device,
It has an ejection port which is an ejection space provided on the post-processing device side located on the opposite side of the form feeding device with respect to the turn bar.

Function The continuous foam is changed in direction and turned inside out as it passes through the turn bar, and then passed through the form feeding device and turned inside out again. After forming a loop below the turn bar, it is sent to the post-processing device. It will be sent. Therefore, in the present invention, the continuous foam is sent to the post-processing device in the same front and back state as before passing through the turn bar, and the transport direction is changed to the transverse direction with respect to the original direction, and The loop forming space below the turn bar functions as a buffer section.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, FIG. 1 is a perspective view with a part of the main part cut away, and FIG. 2 is a perspective view showing a state in which the continuous foam is transferred when combined with other devices.

As shown in FIGS. 1 and 2, the turn bar 1 horizontally and to the left moves the continuous form 3 that has been guided by the hold down stay 2 placed at the top of the loading entrance, which is the loading space. In order to change the direction by 90 degrees, press against the presser stay 2.
It is removably installed so that it extends diagonally at a 45 degree angle. The continuous form 3 is made up of a large number of unit forms each having a marginal portion with a marginal hole on both sides in the width direction, each of which has a marginal hole at the cut-off perforation. Further, in front of the continuous foam 3 in the transport direction, the continuous foam 3 transported through the turn bar 1 forms a loop in a loop forming space 15 which is a space below the turn bar 1, and temporarily stores the continuous foam 3. In order to make this possible, a feed roll 4 is rotatably provided to guide the continuous foam 3 downward in the direction of the turn bar 1. This feed roll 4 is connected to a reversibly rotatable rotary drive source (not shown), and usually sends out the continuous form 3 downward. is a feed roller 6 rotatably supported by the support member 5 in order to smoothly perform the above-mentioned feed operation.
are in contact with each other. The feed roll 4 and the feed roller 6 constitute a form feeding device. Further, the rotation direction of the feed roll 4 can be reversed by a changeover switch, so that the continuous form 3 can be fed in reverse.

Similarly, as shown in FIGS. 1 and 2, on the opposite side of the turn bar 1 from the feed roll 4, a loop is formed in a loop forming space 15 via the feed roll 4, and then transferred. A detatcher 7, which is a post-processing device for cutting the continuous foam 3 into unit forms, is provided, and in front of the detatcher 7, a presser stay 8 is provided for guiding the continuous form 3 to an exit portion, which is a delivery space. ing. The detacher 7 is a first
As can be understood from the figure, there is a guide plate 9 provided with a pair of left and right regulating plates 9a and 9b for regulating the widthwise position of the continuous form 3 provided slightly above the presser stay 8, and a cutaway (not shown). A pair of left and right transport tractors 10a and 10b are provided in the section for transporting the continuous form 3 positioned at predetermined positions in the width direction of the pair of regulating plates 9.

As shown in FIG. 2, the continuous form 3 is fed from the outlet 12 provided at the bottom of the automatic paper feeder 11.
The paper is supplied to a printer (not shown), and after predetermined printing is performed by the printer, it is ejected from the printer, and is turned horizontally by 90 degrees by a turn bar 13 provided at the top of the automatic paper feeder 11. , and is configured to be turned over and supplied to the presser stay 2. The continuous forms 3 cut into unit forms by the detatcher 7 are successively stacked on a stacker 14.

Although not shown, in order to detect the loop tip of the continuous form 3 in the loop forming space 15, a plurality of sensors are installed at predetermined height positions, and depending on the detection state, the transfer tractor Continuous form 3 by 10a, 10b
The transfer speed of the printer is controlled to coordinate with the printing operation of the printer.

Next, the operation of the above-mentioned embodiment will be explained in FIGS. 1 and 2.
This will be explained based on the diagram.

The continuous form 3 supplied from the outlet 12 of the automatic paper feeder 11 to a printer (not shown) has a predetermined print on its surface by the printer, and then passes through a turn bar 13 to be turned 90 degrees horizontally. At the same time as the direction is changed, the paper is transported to the presser stay 2 at the import entrance with the paper reversed so that the back surface 3b is on the upper side.

When the continuous form 3 guided and transferred by the holding stay 2 passes through the turn bar 1, its direction is changed horizontally by 90 degrees, and the continuous form 3 is turned inside out, with the front surface 3a facing upward and placed on the feed roll 3.
and is guided downward by the feed rolls 4 and 6. Next, a loop is formed in the loop forming space 15 below the turn bar 1, and the front and back surfaces are reversed so that the back surface 3b is on the upper side again. It is guided by a stay 8, supplied to a detatcher 7, and cut into unit forms.

Form a loop as described above to form a continuous form 3
By temporarily storing the loop length, it is possible to adjust the processing speed of the printing operation in the printer and the cutting operation in the datatcher 7 within the range of this loop length, so that the loop length is always within a certain range. The speed at which the continuous form 3 is transported by the transport tractors 10a, 10b of the detacher 7 is controlled. The continuous forms 3 cut into unit forms by the detatcher 7 are sequentially stacked on the stacker 14 in a predetermined order.

Note that the present invention is not limited to the embodiments described above, and for example, the form feeding device may include a combination of the feeding roll 4 and the feeding roller 6, as well as a rotating member connected to an appropriate rotational drive source, and an idler. It may also be a combination of rolls, curved guide plates, etc. Further, the turn bar 1 may be configured so that its inclination direction is opposite to that of the above-mentioned embodiment so as to turn the transferred continuous form 3 horizontally by 90 degrees to the right side. The direction change does not necessarily have to be 90 degrees. When the direction is changed to the right side as described above, the positional relationship between the feed roll 4 and the detatcher 7 is opposite to each other. Further, the post-processing device is not limited to the detatcher 7, and the combined devices are of course not limited to the automatic paper feeder 11 and the printer.

Effects As is clear from the above explanation, according to the present invention, it is possible to change the transport direction of the continuous form to the lateral direction and feed the paper to the post-processing device with the front and back sides being the same. Since it is now possible to carry in the equipment from the side, the arrangement of each equipment to be combined can be set in various ways, making it possible to use space more effectively.
The absence of complex reversing mechanisms that can cause jams allows for smooth transfer and processing of continuous forms, and even the formation of loops required when combining with other equipment is done below the turn bar. It has many advantages, such as not requiring any extra space.
