Description

  The present invention relates to a turn bar device that changes and adjusts a conveyance state by winding and unloading a turn bar disposed on a conveyance path when conveying a web that is a long belt-like sheet material.

  In recent years, in order to meet the demand for diversification and increase in volume of information processing, an electrophotographic image forming process has been adopted, enabling high-speed processing using continuous paper (web) as a transfer medium (recording medium). The printer device is used.

  In general, a high-speed printer device requires a large amount of print processing. Therefore, in order to meet the demand for resource saving as double-sided printing, the market demand for a printer device system that prints on both sides of continuous paper is increasing year by year. The trend is increasing.

  In such a high-speed printer device using continuous paper, if it is configured to print on both sides of continuous paper as a single unit, one printer device is too large and too heavy, and it can also be used for duplex printing. It will be limited.

  In view of this, development of a multiple printer device system in which two high-speed printer devices arranged in a perpendicular direction are connected by a conveyance path in which a turn bar device is arranged in a right-angled corner is being developed.

  In such a printer device system using a turn bar device, the continuous paper which is printed on the front side by the first printer device and then transported to the conveyance path is turned over by the turn bar device on the conveyance route and the back surface of the continuous paper to be printed. Is turned up and the conveying direction is changed to a right angle, and then the sheet is carried into the second printer device and printed on the back surface of the continuous paper to complete double-sided printing on the continuous paper.

  In a printer apparatus used in such a printer apparatus system, it is normal that the reference position of continuous paper necessary for image forming processing is one side of the continuous paper.

  Therefore, in the second printer device in which the continuous paper printed on the front side by the first printer device is carried in by turning the web upside down by the turn bar device, the reference position of the continuous paper is changed and the other side of the continuous paper is changed. The side is the reference position. That is, it is necessary to carry in the continuous paper that is carried in with the web turned over to the entrance of the second printer device with the other side aligned with the reference position.

  For this reason, when double-sided printing is performed on the front and back of continuous paper (web) using a continuous printer device system, the turn bar device is adjusted every time switching to continuous paper with different width dimensions, and the web is reversed. Therefore, it is necessary to align the other side of the continuous paper that has been replaced with the reference position with respect to the entrance of the second printer device, which is complicated and reduces work efficiency.

  Therefore, looking at conventional means that can adjust the carry-out position of continuous paper (web) to be carried out, similar to a turn bar device, for example, collating to load a roll-like belt-like sheet on a stand and feed it to a conveyance device Sidelay devices in the device have been proposed.

  The sidelay device in this collating apparatus has a positioning hole for a belt-like sheet that is fed from a paper feeding unit and has a positioning hole formed continuously along the longitudinal direction, and is arranged substantially perpendicular to the paper feeding direction of the belt-like sheet. The pin belt is configured to be inserted through a continuous pin and conveyed.

  The turn bar of this sidelay device is disposed at an angle of, for example, approximately 45 ° with respect to the feeding direction of the belt-like sheet. The turn bar converts the sheet feeding direction of the belt-like sheet that has been rotated approximately half way along the peripheral surface thereof to a substantially right angle so as to coincide with the conveying direction of the pin belt.

  This turn bar is configured to rotate the male screw part provided in the turn bar parallel moving means with a motor, and by attaching the turn bar to a ball screw consisting of a female screw part screwed into this male screw part, By driving the motor, the turn bar is translated along the sheet feeding direction, and the relative position of the belt-like sheet whose sheet feeding direction is changed with respect to the pin belt is translated.

  That is, when the turn bar parallel moving means translates the set position of the turn bar with respect to the sheet feeding direction, the transport position of the belt-like sheet after the direction change is also translated. Therefore, even if the position of the positioning hole of the belt-like sheet is different, the positioning hole can be inserted into the continuous pin of the pin belt by moving the set position of the turn bar in parallel (see, for example, Patent Document 1).

  Such a conventionally proposed sidelay apparatus is a collating apparatus that collates a plurality of rolls, and an operator having specialized knowledge adjusts the turn bar of the sidelay apparatus as part of the work of exchanging the rolls. It is assumed and the configuration is not concrete.

Therefore, according to the conventionally proposed configuration of the side-lay device, it is arranged between the first printer device and the second printer device in the multiple printer device system and can be switched to continuous paper (web) having different width dimensions. It is difficult to manufacture a turn bar device that can precisely and easily perform turn bar position adjustment work every time even if it is not an operator having specialized knowledge or skilled ability.
Patent No. 3012046

  In view of the above-described problems, an object of the present invention is to newly provide a turn bar device that can perform a position adjustment operation of a turn bar precisely and easily every time switching to a web having a different width dimension.

  The turn bar device according to claim 1 carries in a web reversal in which a web that is a long belt-like sheet material is carried and wound up around a turn bar arranged at an angle of approximately 45 degrees with respect to the web traveling direction.

  With the configuration as described above, when transferring a web in place of a web having a different width in a printer apparatus system that transports a web via a turn bar device, the control means controls the moving means to The table portion on which the turn bar is installed is moved to the web width adjustment position corresponding to the web having a different width dimension with reference to the home position detected by the detection means. For this reason, the table part in which the turn bar is installed can be accurately moved to the web width adjustment position corresponding to the newly set web having a different width dimension. In addition, even if this control operation is repeated many times, movement control is performed with reference to the home position, so that it can be precisely controlled so that the error does not increase. In addition, since the control means automatically performs the operation of moving the table portion where the turn bar is installed to the web width adjustment position corresponding to the web having a different width dimension, the position of the turn bar is changed every time the web is replaced with a web having a different width dimension. Therefore, the work efficiency can be improved, and the trouble caused by forgetting the work of adjusting the position of the turn bar and operating it can be eliminated.

  The turn bar device according to claim 2 carries in a web reversal in which a web, which is a long belt-like sheet material, is carried and wound up around a turn bar arranged at an angle of approximately 45 degrees with respect to the web traveling direction. In the turn bar device that carries out change adjustment of the web carry-out position and carries it out in the direction perpendicular to the carry-in direction, a turn bar attached to the base portion is installed so as to be movable in parallel with the web traveling direction. Corresponding to the target scale member, which is installed on the table part, extending to the base part in the moving direction of the table part, and displaying the scale for positioning according to the width size of the web, and the target scale member in the table part In the position where the table portion is moved, the mark is provided on the scale of the target scale member and the mark is provided on the base portion. For it restrained the Buru portion at a position corresponding to the width size of the web, characterized in that it comprises a stopper mechanism.

  By configuring as described above, when performing conveyance instead of a web having a different width dimension in a printer apparatus system or the like that conveys the web via the turn bar device, the table portion on which the turn bar is installed by releasing the stopper mechanism is provided. After manually moving and aligning the mark displayed on the table unit with a predetermined scale for positioning according to the web width size of the target scale member, the table unit is moved from the base unit with the stopper mechanism. Adjustments can be made by a simple operation of fixing so as not to move. Therefore, the work of adjusting the position of the turn bar every time the web is replaced with a web having a different width dimension can be facilitated to improve the work efficiency.

  The turn bar device according to claim 3 carries in a web which is a long belt-like sheet material, performs a web inversion using a plurality of turn bars, and changes and adjusts the web carry-out position. In the turn bar device for carrying out in a direction parallel to the direction, the first turn bar arranged in an inclined state with respect to the carrying direction in order to change the conveyance direction of the carried web to a direction orthogonal to the direction, and arranged in an inclined state The second turn bar that folds and conveys the web carried from the first turn bar and the second turn bar that folds and conveys the web, and changes the conveyance direction of the web carried from the second turn bar to the orthogonal direction, so that the web is inclined. A third turn bar arranged in a state of intersecting with the arranged first turn bar at right angles to each other, and a first turn bar arranged in an inclined state Among the third turn bar disposed in a state of intersecting orthogonally to one another, and having a parallel movement adjusting means for translating those mounted movably at least one of the parallel, the.

  By configuring as described above, it is possible to change and adjust the carry-out position of the web and carry it out in a direction parallel to the carry-in direction. Therefore, the two printers etc. constituting the multiple printer apparatus system are arranged in a row. It can be placed in a narrow installation place. When carrying a web in place of a web with a different width dimension in a printer system that transports the web via a turn bar device, etc., using the parallel movement adjustment means, to the web width adjustment position corresponding to the web with a different width dimension The table part where the turn bar is installed can be moved and adjusted. Therefore, the work of adjusting the position of the turn bar every time the web is replaced with a web having a different width dimension can be facilitated to improve the work efficiency.
