Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a winding device for a friction string material used for preforming an annular friction disk (facing) for a clutch or a brake.

[Prior Art] Conventionally, when preforming an annular friction disc body (facing) for a clutch or brake, a seventh
A pin-type winding device as shown in the figure, that is, two groups of pins protruding from a rotatably driven face plate unit 1 is used to wind up the friction string material 3 in a predetermined pattern so as to form an annular shape with a predetermined thickness. A winding device was used to form the friction disc.

Note that the above-mentioned winding device is a so-called vertical winding device in which two groups of pins are provided protruding in the vertical direction.
On the other hand, a horizontal winding device having a group of pins projecting horizontally has also been used, as disclosed in, for example, Japanese Unexamined Patent Publication No. 59-202280.

[Problems to be solved by the invention] However, in these conventional winding devices,
The porous pressing plate 4 that presses the string material layer wound around the two groups of pins is composed of a disc body, and this is pressed against and separated from the face plate unit 1 via an actuator 5 fixed to a fixed frame. Therefore, when pressing, it was necessary to move the string guide 6 to the position shown by the chain line, and also move the face plate unit 1 so that the pins 2 could be inserted into the holes of the pressing plate 4. The rotation must be stopped in a positioned state, and therefore, there is a drawback that winding must be interrupted during the pressing process. Note that it is preferable to press the string material layer wound around the second group of pins each time the friction string material 3 is wound around the second group of pins in order to prevent deformation.
If carried out in this way, the number of interruptions in winding increases and the time required for preforming becomes longer, so winding has to be carried out every time a plurality of turns are wound.

The present invention has focused on such a problem, and as a result of intensive studies from various aspects in order to solve this problem, the porous press plate is composed of a divided body of a disc body, and this is connected to the face plate unit during rotational driving. They discovered that it is only necessary to attach it so that it can be pressed into contact with and separated from it.

[Means for Solving the Problems] That is, the friction string material winding device according to the present invention winds up friction string materials in a predetermined pattern using a group of pins protruding from a rotationally driven face plate unit. When forming an annular friction disc body having a predetermined thickness, in a friction string material winding device equipped with a porous pressing plate that presses the string material layer wound around the pin group, the porous pressing plate The device is characterized in that it is constructed of a divided disc body, and is mounted so as to be able to press against and separate from the face plate unit while it is being rotated.

0 is fixed with bolts 21 and the bottom plate 2
0, nine pins 2 are located on the same circumference and protrude from each other at equal intervals.

Note that 15 is an oil-less bearing, the housing 19 is fixed to the device frame 22, the 2 groups of pins are inserted into the 24 groups of through holes drilled in the top plate 23, and the top plate 23 is , is fixed to the upper end of the rod 18 via a spacer 25, a presser foot 26, and a nut 27, and the presser foot 25
As shown in FIG. 4, both ends of the rod 18 are pressed against the top plate 23 by the tightening force of the nut 27, and the lower end of the rod 18 is connected to the rod of the actuator 28 shown in FIG. In other words, the rod 18 can rotate, but the rotational force is not transmitted to the rod of the actuator 28, and the vertical movement of the rod of the actuator 28 causes the rod 1 to rotate.
8 are connected via a predetermined shaft coupling mechanism so that they can be moved up and down.

Therefore, in the face plate unit 1, by starting the servo motor 7 and driving the gears 8 to 11, the table 14, the upper face plate 20, the lower face plate 23, and the rod 18 can be rotated together, and By operating the actuator 28, the top plate 23 can be moved up and down. In this example, the face plate unit 1 is provided so that it can be rotated to the right.

Next, referring to the porous press plate 4, this press plate 4 is attached to the face plate unit 1 so as to be able to press against and release from the crank 29.

That is, the crank 29 is connected to the gears 9, 30 to 33.
In this case, the arm 34 is guided by a guide bar 35 and moves up and down, and the shaft 36 to which the porous press plate 4 is fixed to the lower end is moved up and down. make it move.

Note that the porous press plate 4 is composed of a divided disk body, and is provided in a fan-shaped body with an angle of 160 degrees.
Further, four holes (elongated holes) 37 for inserting two groups of pins protruding from the face plate unit 1 are provided through this.

Therefore, if the multi-hole pressing plate 4 is moved downward with these holes 37 positioned in a predetermined position relative to the two groups of pins protruding from the face plate unit 1, this plate 4 will be moved above the face plate unit 1. It can be pressed against the face plate 23, but this positioning is done by the gear 9.
The disc groove cam 38 is rotationally driven through the rack 3.
This can be done by rotating the pinion 40 by sliding the shaft 36 in a predetermined direction.

That is, the porous pressing plate 4 has the following characteristics in FIG.
The pins 2 at positions a to d are positioned so that they can be inserted into the holes 37, moved downward, and pressed against the top plate 23 of the face plate unit 1. Then, when it rotates to the right together with the face plate unit 1 and the pin 2 inserted into the hole 37 is moved to positions d to g,

In FIG. 1, one of the friction cord materials 3 is shown wound up by the pin 2 at the position i shown in FIG.
The pin 2 at position h, which is moved to the center side of the face plate unit 1 and then moved to the winding position, connects the other friction string material 3 (the one that was not wound up by the pin 2 at position i). The friction string material) is wound up, and then the string material guide 6 is moved to the original position,
One of the friction string materials 3 (the one wound up by the pin 2 at position i) is wound up by the next moved pin 2 at position g, and in this way,
The friction string materials 3 can be wound up one after another in a state where they are crossed and overlapped with each other.

Note that this winding is continued until a predetermined number of circumferential windings are completed, and in parallel with this, the porous pressing plate 4 presses the string material layer wound around the two groups of pins. That is, the porous pressing plate 4 is provided so that it can be moved downward and pressed every time the friction string material 3 is wound around the pin 2 group, but during this pressing, the porous pressing plate 4 Since it is composed of a divided body, it does not come into contact with the string material guide 6 located on the top plate 23.

During the winding process, the string material guide 6
It is located on the top plate 23 and near the position i and is moved in the direction of the arrow shown in the figure, but the porous press plate 4, as described above, is moving the pins 2 at positions a to d. The pin 2 is positioned so that it can be inserted into the hole 37 and moved downward, and when the pin 2 inserted into the hole 37 is moved to positions d to g, it is moved upward, so press it while winding it up. This makes it possible to produce more annular friction discs (facings) of uniform density per unit time.

In order to keep the pressing force constant, the height of the porous pressing plate 4 is adjusted to a predetermined value by an actuator 48 according to the thickness of the wound string material layer. Further, a pusher 49 is provided for transferring the preformed annular friction disc body from above the face plate unit 1 to another location. In the state in which the face plate 23 is moved to the tip of the second group of pins, the preformed product (annular friction disk) that has been separated from the second group of pins and placed on the top plate 23 is pushed and transferred. Note that this transfer is performed with the string material guide 6 being moved from above the top plate 23 to another location, and this movement of the string material guide 6 is controlled by the actuator 49, and the string material guide 6 is moved from the top surface plate 23 to another location. 23 If you move from above to another place, cutter 50
