  Japanese Patent Laid-Open No. 2000-143045 discloses a paper threading device for threading continuous paper that has been threaded to the drag roller immediately upstream of the former along the former. This device conveys the leading end of continuous paper that has been passed through the drag roller just upstream of the former by some means, and is driven by the driving roller to wrap around the side of the former across the side of the former. Inserted between the belt and the former surface, and the continuous displacement of the conveyor belt causes the continuous paper to pass through the former surface and fold the former in parallel with the paper threading direction. It leads to the lower nipping roller.

  Further, there is an apparatus disclosed in US 2005/0269379 A1 that automates paper threading downstream from the former. This apparatus is configured to pass the continuous paper into the folding device by a flexible threading member that is driven and moved in the guide. However, in general, there is a method in which an operator grasps a leading end of continuous paper fed from a nipping roller immediately below the former and guides the paper along a desired paper travel path.

Japanese Patent Publication No. 2-30978 Japanese Patent Publication No. 2-61393 Japanese Utility Model Publication No. 4-50278 Japanese Patent Publication No. 6-88696 JP 2000-143045 A Japanese Patent Publication No.58-015418 JP-A-61-090957 US2005 / 0269379A1

As already mentioned, the conventional web threading device of a rotary press is until the drag roller just upstream of the former, which is the entrance of the folding device, or until it reaches the nipping roller just below the former along the former surface. It is common to be able to carry out the web threading between the two without operator intervention.
Recently, it has become possible to pass through continuous paper (paper guidance) without any operator intervention in the folding apparatus.

  However, as described above, the automatic paper threading in this folding device is loaded with a flexible threading member in a guide provided in advance, and this paper threading member combined with continuous paper is driven to follow the guide. It is a mechanism that moves according to its complexity, such as dealing with troubles caused by movement of the paper threading member in the guide, dealing with wear that occurs between the two, etc. It requires considerable labor and cost for maintenance and maintenance.

  In addition, this automatic paper threading device is capable of guiding continuous paper only along a guide provided in advance, and is not disclosed for the case where the paper guide destination branches into a plurality of downstream downstream of the former. It is. On the other hand, in the paper corrugator field, the web guide mechanism disclosed in Japanese Patent Publication No. 58-015418 and Japanese Patent Application Laid-Open No. 61-090957 has a guide portion and a web directing device arranged along the web path, and The end portion of the web directing device is adjacent to both ends of the guide portion of the upstream web path and the guide portion of the downstream web path, and both the guide portions are configured to be continuous. Of course, it is not a mechanism that can be used as a paper threading mechanism of a device that forms a web path during operation and that runs continuous paper at an extremely high speed (10 to 15 meters per second) as in a rotary press. The continuous paper threading device is a device having a completely different technical idea in terms of mechanism.

For this reason, the paper threading into the folding device is still often performed manually by the operator, such as when the continuous paper guide destination is branched downstream of the former, and the folding device is rotated. Manual operation by the operator under the condition that the operating part is rotating is dangerous even though the rotation speed is low. This manual operation is completely abolished and the continuous paper is automatically guided to a desired guide destination. Possible devices are strongly desired to ensure the safety of workers. In addition, under the installation of a device that can automatically guide continuous paper to a desired destination, it is possible to perform normally necessary operations such as maintenance management for the other parts of the folding device as well as the device as usual. Is strongly desired.
The object of the present invention is to meet the above-mentioned demand with a very simple mechanism.

The paper guide device of the folding device of the present invention is a paper guide device that guides continuous paper along a paper travel path from a former to a folding cylinder when passing continuous paper through a rotary press. Paper having a plurality of guide members that form inclined surfaces extending from an upstream nipping roller to a downstream nipping roller in the guide direction, and each guide member is a paper on which continuous paper travels during printing operation. It is provided at a position separated from the traveling path facing upward, and the upstream guide member is positioned so as to face the sending side outer peripheral surface of both of the two rollers forming the nip of the upstream nipping roller, The downstream side of the downstream guide member is positioned such that one of the two rollers forming the nip of the downstream nipping roller faces the pulling side outer peripheral surface downward.

  The guide means is divided into several parts in the direction of guiding the continuous paper, and the upstream end side of the guide member of the downstream guide means between the adjacent guide means is downstream of the guide member of the upstream guide means. Furthermore, the upstream end side of the guide member of the downstream guide means is between the adjacent upstream nipping roller or the downstream side of the guide member of the upstream guide means. It is located with a separation space where the operator can work with his arms inserted.

Corresponding to the folding device in which the paper travel path is branched into a plurality, guide means capable of angular displacement of the guide member is provided near the lower part of the branch position, and a desired member is selectively selected by the angular displacement of the guide member. It enables continuous paper guidance along the paper travel path.

In the paper guide device of the folding device according to the present invention, the leading end of the continuous paper fed from the upstream nipping roller is formed by the two rollers that form the nip of the upstream nipping roller. It is caught by the guide surface of the guide member arranged so as to face the outer peripheral surface of the delivery side, and as it is fed to the nipping roller, it reaches the downstream side of the guide member according to the inclination of the guide member by gravity, and further the nipping roller From the downstream end of the guide member immediately above, the guide member reaches the outer peripheral surface of the pull-in side of one of the two rollers that form the nip of the downstream nipping roller facing downward, and the rotation of this one roller It is drawn into the nip of the downstream nipping roller.
Accordingly, it is possible to eliminate paper thread in the folding device by the operator's manual work, and it is not necessary for the worker to work close to the operating folding device, and the safety of the worker is reduced. Secured.

Also, the paper guiding device of the folding apparatus according to the invention, arranged a guide member in position, with an extremely simple configuration in which only was to help orientation when the continuous paper is down downward by gravity As a result, the increase in the number of dangerous parts of the folding apparatus can be minimized, and the frequency of occurrence of failures and the like can be suppressed to a very low level, thereby maintaining the performance and reducing the maintenance labor.
In addition, since the paper guide device of the folding device according to the present invention is provided at a position separated from the paper travel path on which the continuous paper travels during the printing operation, the guide member is an obstacle to the continuous paper travel during the printing operation. It can eliminate the fear of becoming.

Further, in the present invention, the selective switching of the plurality of paper guide destinations can be performed very easily only by the operation of changing the inclination direction of the divided guide member without requiring the manual operation of the operator, and the plurality of paper guide destinations. The addition of the operation of selectively switching the guide destination is an extremely simple configuration of only the angular displacement operation of the guide member at the branch point of the guide means divided in the guide direction of the continuous paper. The increase can be minimized, and the frequency of occurrence of failures and the like can be kept extremely low, so that the performance can be maintained and the maintenance labor can be reduced.
According to the second aspect of the present invention, the upstream end side of the guide member and the adjacent upstream side nipping roller pair between the two outer peripheral surfaces of the two opposing rollers, or upstream of the guide member. Since the separation space is provided between the end side and the back side of the guide member on the upstream side of the guide member on the downstream side of the guide member, the operator can insert his / her arm. Needless to say, normally necessary operations such as maintenance management can be performed on the other parts of the folding apparatus in substantially the same manner as before.

It is intended to ensure safety when working in the vicinity of the guide member, and is not limited to the illustrated shape. Further, the downstream end of each guide member of the fixed guide means 30, 40, 50 is not rounded because the end portion is provided with a roller near the lower side, and this roller hides the downstream end of the guide member. Of course, the end portion may be formed in the same manner as the upstream end.

The operation of the paper guiding device of the folding device will be described with reference to the drawings.

It is wound and sent to the downstream side by the rotational drive of the upstream drag roller DR. At this time, when the continuous paper W has a width extending over the two formers FM and FM, the traveling direction is caused by the slitter SL displaced to the cutting action position to be inserted into the groove provided on the outer peripheral surface of the upstream drag roller DR. To be two continuous paper W.

The continuous paper W is passed through the paper travel path from the former to the folding cylinder in the folding device by the paper guiding device 1 as follows.
The continuous paper W fed downstream by the rotational drive of the upstream drag roller DR is formed horizontally on the upper surface and side surfaces of the former FM, and on both sides near the lower end of the former FM, and at right angles to the upstream drag roller DR. Guided by the FO, both sides of the lower side of the former FM change 90 degrees in the opposite direction with respect to the lower tip passage part, and proceed downward by gravity while being folded in parallel with the traveling direction. The leading end of the continuous paper W reaches the upstream nipping roller pair NR11 or the upstream nipping roller pair NR12 and is drawn into the drawing nip, and the continuous paper W is firmly creased parallel to the running direction. At the same time, it is sent out downward.

  Of the continuous paper W sent out with the above crease, the leading end of the continuous paper W sent downward by the upstream nipping roller pair NR11 is provided below the upstream nipping roller pair NR11. The moving direction of the movable guide means 10 is changed to either the direction of the downstream nipping roller pair NR21 or the direction of the downstream nipping roller pair NR22 depending on the inclination of the guide surface 11a of the movable guide means 10, and the downward direction according to the inclination. Proceed to.

  More specifically, when the output rod of the linear actuator 14 of the movable guide means 10 is retracted and the guide member 11 is inclined downward to the left as shown by the solid line in FIG. 1, it is lowered by the upstream nipping roller pair NR11. The leading end of the fed continuous paper W hits the guide surface 11 a of the guide member 11, proceeds to the lower left while changing the traveling direction according to the guide surface 11 a of the inclined guide member 11, and gravity again from the left end of the guide member 11. Continue further down.

  Then, it reaches the fixed guide means 30 provided below the movable guide means 10, hits the inclined guide surface 31 a of the guide member 31, proceeds to the lower left while changing the traveling direction according to the guide surface 31 a, and guide member 31. 1 to the outer peripheral surface of the guide roller GR1, and proceeds downward along the left peripheral surface in FIG.

  Further, the leading end of the continuous paper W reaches the fixed guide means 40 provided below the fixed guide means 30, hits the inclined guide surface 41a of the guide member 41, and changes the traveling direction according to the guide surface 41a. The left nipping roller pair NR21 is drawn from the left end of the guide member 41 to the outer peripheral surface of one of the two rollers forming the nip of the downstream nipping roller pair NR21. It is drawn into the nip and guided to be fed into the blade folder BF provided below the nip.

Thus, the continuous paper W fed downward by the upstream nipping roller pair NR11 is passed through a desired traveling path from the former FM to the folding mechanism F.

  On the other hand, among the continuous paper W sent out with the above crease, the leading end of the continuous paper W sent downward by the upstream nipping roller pair NR12 is below the upstream nipping roller pair NR12. The traveling direction is changed to either the direction of the downstream nipping roller pair NR21 or the direction of the downstream nipping roller pair NR22 depending on the inclination of the guide surface 21a of the guide member 21 of the movable guide means 20 provided in the Proceed downward.

  More specifically, when the output rod of the linear actuator 24 of the movable guide means 20 retracts and the guide member 21 is steeply inclined to the left as shown by the solid line in FIG. 1, the upstream nipping roller pair NR12. The leading end of the continuous paper W fed downward by the contact with the guide surface 21a of the guide member 21 advances to the lower left while changing the traveling direction according to the guide surface 21a of the inclined guide member 21, and the left end of the guide member 21 To the outer peripheral surface of the guide roller GR2, and proceeds downward in accordance with the left peripheral surface in FIG.

  And it reached the drawing side outer peripheral surface of one of the two rollers forming the nip of the downstream nipping roller pair NR22, and was drawn into the drawing nip of the downstream nipping roller pair NR22 according to the rotation of the roller, and provided below that Guided to Joufolder JF.

  Unlike the above guide, the output rod of the linear actuator 24 of the movable guide means 20 is extended, and the guide member 21 is looser than the state in which the output rod of the linear actuator 24 is retracted as shown by a two-dot chain line in FIG. When the slope is inclined downwardly to the left, the leading end of the continuous paper W fed downward by the upstream nipping roller pair NR12 hits the guide surface 21a of the guide member 21, and the guide surface 21a of the inclined guide member 21 is inclined. In accordance with the direction of travel of the guide member 21, the guide member 21 moves from the left end of the guide member 21 to the guide surface 31a of the guide member 31 of the fixed guide means 30 positioned below the guide member 21, and travels in accordance with the inclined guide surface 31a. The left side of the guide member 31 reaches the outer peripheral surface of the guide roller GR1 from the left end of the guide member 31. It travels downward in accordance with.

  Further, the leading end of the continuous paper W reaches the fixed guide means 40 provided below the fixed guide means 30 by gravity, hits the inclined guide surface 41a of the guide member 41, and travels along the guide surface 41a. The left nipping roller pair NR21 is moved from the left end of the guide member 41 to the outer peripheral surface of one of the two rollers forming the nip of the downstream nipping roller pair NR21. It is drawn in to the drawing nip and is guided to be fed into a blade folder BF provided below the drawing nip.
