Description

[Detailed description of the invention] [Field of industrial application] The present invention is a method for adjusting the presser roll, which freely adjusts the position of the presser roll that presses the printing paper or film wound onto the take-up reel, in the winding device of a printing press. Regarding equipment.

[Problems to be solved by the prior art and the invention] Conventionally, a presser roll is used for the film and the like to be wound up on the above-mentioned take-up reel in order to keep the winding pressure constant. However, when winding a film onto a take-up reel, the winding pressure will not be constant unless the pressing surface of the presser roll is in constant contact with the left and right sides.
Further, if there is an angle in the pressing direction of the presser roll, there are disadvantages such as changes in the overlap of the edges of the wound film or the like. Therefore, this inconvenience must be corrected, but the contact adjustment for pressing and the adjustment of the presser foot angle must be performed separately, making the adjustment very troublesome, troublesome, and difficult. It was hot.

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention was devised for the purpose of solving the above-mentioned conventional problems. One end of the presser roll shaft is supported on one of the swing pieces, and the other end of the shaft is
The other rocking piece is pivotally supported by a movable bearing member in a frame attached to the side surface of the other rocking piece through a loose fitting hole provided correspondingly to the shaft support, and the movable shaft supporting members are arranged opposite to each other. It is attached to two adjustment shafts arranged in the X and Y directions perpendicular to the frame having a long hole in the center, and furthermore, each adjustment shaft is provided with a threaded part, and this threaded part is connected to each of the corresponding one of the abovementioned parts. It is hinged with a nut having a handle that is fitted into an elongated hole to allow rotation and movement, and the other end of the shaft is fitted into the other elongated hole, and a bearing body that cooperates with the nut is fitted, so that the handle can be rotated and moved. The position of a movable bearing member that pivotally supports the shaft of the presser roll via an adjustment shaft can be moved to any position on the X and Y coordinates by rotation, so that the position and direction of the presser can be easily adjusted.

[Embodiment] Next, an embodiment of a presser roll adjusting device in a winding device of a printing press according to the present invention will be described based on the drawings.

Reference numeral 1 denotes a presser roll, and the presser roll 1 is rotatably fitted and supported by a shaft 3 via ball bearings 2, 2. The shaft 3 has one end supported by a spherical bearing 4 on one swing piece 5 of a pair of swing pieces 5, 5a, the other end of which is supported on the body side. The other end of the shaft 3 is pivotally supported by a spherical bearing 8 on a movable bearing member 7, which will be described later, through a loose fitting hole 6 formed in the other swinging piece 5a.

A substantially rectangular frame 9 is attached to the side surface of the swinging piece 5a on the side in which one of the loose fitting holes 6 is bored, and the movable bearing member 7 is housed within the frame 9. Long holes 10, 10a and 11, 11a in the longitudinal direction corresponding to each other are provided in the center of each side of the frame 9.
Flanges 14a, 1 are screwed into threaded portions 12a, 13a screwed onto one ends of the direction adjustment shafts 12, 13.
A bearing body 1 in which nuts 14 and 15 provided with grooves 5a are rotatably fitted, and the other ends of adjustment shafts 12 and 13 are slidably fitted into the corresponding elongated holes 10a and 11a, respectively.
6, 17 are movably fitted, and further the bearing body 16,
17 is provided with flanges 16a and 17a, respectively, and these flanges 16a and 17a are applied to the inner surface of the frame 9, respectively, and slidable collars 16b and 17b that are fitted and fixed to the adjustment shafts 12 and 13, respectively, are applied to the outer surface. The holes 10a and 11a are movable.

Nuts 14 and 15 fitted into the long holes 10 and 11
The flanges 14a, 15a are respectively placed on the inner surface of the frame 9, and the outer surface has slidable rings 14b, 15b.
The handles 18 and 19 are fitted and attached through the handles 18 and 19, and the nuts 14 and 15 are rotated through the handles 18 and 19, respectively.

The orthogonal adjustment shafts 12 and 13 are inserted into and fixed in the movable bearing member 7, and can be moved to any position in the X and Y coordinates via the adjustment shafts 12 and 13 by rotation of the handles 18 and 19. Become.

[Function] As is obvious from the above structure, in the present invention, the presser roll 1 is placed on the paper or film and wound onto the take-up reel along the presser roll 1. The left and right sides are in equal contact,
Alternatively, if the presser foot is on the same line as the axis and no angle occurs, you can leave it as is, but if the left and right contacts are not the same and the pressure on one side is different, rotate the handle 18 that moves it in the vertical direction. By vertically moving the movable bearing member 7 via the adjusting shaft 12, the shaft 3 of the presser roll 1, which is pivotally supported by the swinging piece 5, can be moved vertically around the pivot point. By finely adjusting the adjustment shaft 12, even and reliable contact can be achieved.Furthermore, when an angle occurs in the pressing part with the reel, the other handle 1
Adjustment can be made by rotating the presser roll 9 and moving the presser roll 1 to the left and right in the same way as described above, and the presser roll 1 can be adjusted by operating the handle as described above.
By simultaneously turning both handles 18 and 19, the position of the movable bearing member, that is, the spherical bearing 8 of the shaft 3 supported by the movable bearing member can be moved to any desired position on the X and Y coordinates.

[Effect] As described above, in the present invention, the movable bearing member built into the frame and attached to two adjustment shafts perpendicular to the frame has a handle screwed onto the threaded portion of each adjustment shaft. It can be moved freely in the X and Y coordinates in the vertical, horizontal, or diagonal directions using a nut, one end is pivotally supported on a swinging piece, and the other end is movable through the loose fitting hole of the other swinging piece that corresponds to the swinging piece. This is for adjusting the position of the presser roll supported by a bearing member, and can be easily adjusted to any position.
