Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to an apparatus for correcting the posture of a web, such as a newspaper, on a conveyor that conveys the web.

Prior art and its problems Generally, a cylindrical web A is shown in FIGS. 1 and 7.
As shown in the figure, the web is conveyed in the longitudinal direction by a slat conveyor with a recess in the center. However, when the web is conveyed to the binding machine by the conveyor, the web is slanted to the conveyor as shown in Figure 5. When riding a bicycle, the band of the binding machine may be tied diagonally or come off.

Furthermore, in the case of a conveyor that transports the web into a machine that inserts and sets the chuck nose into the paper tube core of the web, if the web is tilted, the cone nose cannot be inserted.

Therefore, conventionally, pusher means 10, 10' as shown in FIGS. 5 and 6 push out the obliquely mounted web A toward the inclined chute 20, and correct the posture while returning again. However, in this case, the stroke of the pusher means was made large, the tilting chute 20 was also made large, and the angle was made large so that the posture was completely corrected.

However, in this method, the pusher means is large and the cost is high, and the amount of movement of the web by the pusher means is large, which is disadvantageous in terms of space and requires a long operation time.

Another method is to install two rollers that move up and down on both sides of the conveyor to lift the web, but this requires large equipment and is naturally expensive.The minimum diameter of the web that can be processed is limited by the frame of the conveyor. It requires more than the width, and small diameter ones have the disadvantage that posture cannot be corrected.

Means and Effects for Solving the Problems The present invention has a pusher means for correcting the attitude of a web paper diagonally mounted on a slat conveyor that conveys the web paper in the longitudinal direction, and the pusher means has a This problem has been solved by a web orientation correcting device on the web transport conveyor, which guides the slats slightly upward in position.

In order to correct the slanting of the web A, it is necessary to rotate the web A as shown by the curved arrow in Fig. 5, but if the slat of the conveyor is guided to be slightly lifted at the center position of the pusher means, When pushed by the pusher means and returned from the inclined chute onto the conveyor, the web A is rotated and straightened.

If the slats of the conveyor are not guided so as to be slightly lifted, the conveyor will simply roll without correcting its posture, as shown by the straight arrow in Figure 5, and the intended purpose will not be achieved.

That is, in the present invention, the slat of the conveyor is guided to be slightly lifted at the center position of the pusher means as described above, so when the web is pushed in the inclined chute direction by the pusher means, the orientation of the web is corrected. When the paper web returns from the inclined chute to the conveyor, its orientation is corrected so that it is straight with respect to the conveyor.

Embodiment The conveyor 30 has a slat 3 having a recess in the center.
A slat conveyor consisting of 0A, 30B, 30C..., with left and right rollers 31A, 3 forming a pair, respectively.
1A', 31B, 31B', 31C, 31C'... convey the web A by being driven by sprockets (not shown).

In the illustrated embodiment, the weight of the web A is supported by a pair of resin rails 32, 32', and the slats 30A, 30B, 30C, . . . slide on the resin rails.

The pusher means 10, 10' are shown in FIGS.
As shown in the figure, the fulcrum 12 is
It is rotated around.

At the center position of the pusher means 10, 10', liners 34, 34' are inserted between the resin rails 32, 32' and the frames 33, 33' so that the upper surface of the conveyor 30 slightly lifts the slats. There is.

The liners 34, 34' are 2 as shown in FIG.
There may be layers or more. Note that the method of slightly lifting the slats of the conveyor by inserting a liner is merely an example, and is not intended to be limiting. For example, resin rails 32, 32'
The shape of the rollers 31A, 31 may be formed into a convex shape as shown in FIG. 8 when viewed from the side.
In the case of a normal system in which A', 31B, 31B', 31C, 31C', . . . are guided by rails, the rails may be slightly raised.

Note that the center of the web A and the pusher means 1
It is necessary for the pusher means 10 and 10' to push the web A with the centers of 0 and 10'aligned;
Coincidence of the center positions can be achieved by, for example, positioning a phototube in front of the pusher means, detecting that the web has come to the reference position, and determining the timing at which the center positions coincide based on the length of the web and the conveyor speed input in advance. You can find out by calculating.

Effects of the Invention Since the present invention is configured as described above, it has the effect of providing a paper web posture correction device that does not take up much space.
