Description

Detailed Description of the Invention (Field of Industrial Application) This invention is mainly used in a press processing line for linear materials such as strip metal plates, wires, tapes, etc. The present invention relates to a winding machine for winding onto a reel.

(Prior art) Conventionally, this type of winding machine has been used, for example, in
There was an automatic winding device disclosed in Publication No. 144820. In this winding device, a winding reel (winding spool) on which a wire-like material is wound is held by a chuck member, and is moved from a winding position to a storage position by the swinging of the chuck member. A new take-up reel is placed at the take-up position, and the take-up reel is replaced with a new one (hereinafter referred to as reel exchange).

(Problems to be Solved by the Invention) In the above-described conventional automatic winding device, when replacing the reel, there are two steps: a step of moving the take-up reel to the removal position by the chuck member, a step of chucking the take-up reel by the chuck member; There are many processes involved in replacing the take-up reel, such as an unloading process for transporting the take-up reel to the storage position and a preparation process for equipping a new take-up reel, and there is a problem in that it takes a long time to replace the take-up reel. .

(Means for Solving the Problems) In order to solve the problems in the above-described conventional technology, the present invention is such that at least two driven side reel flanges are rotatably mounted on the turntable.
The turntable is arranged to be selectively movable to a predetermined winding position by rotation of the turntable, a movable base adjacent to the turntable is provided to be movable forward and backward, and a driving side reel flange is wound on the movable base. The gist of the configuration is that the take-up reel is arranged so that it can be actively rotated by a take-up drive source, and can clamp the take-up reel in cooperation with the driven side reel flange at the take-up position when the movable base moves forward. It is something to do.

(Function) According to the above means, after the driven side reel flange on which the take-up reel is attached is moved to the take-up position facing the drive side reel flange by rotation of the turntable, the movable base is moved forward. A take-up reel is sandwiched between both reel flanges, and the material is wound onto the take-up reel by active rotation of the drive-side reel flange by a winding drive source, while the material is wound onto the drive-side reel flange facing the drive-side reel flange. Reel replacement is performed for the driven side reel flange that does not work.

(Example) An example of the present invention will be described below with reference to the drawings. In FIG. 1, which shows the winding machine from the left side, and FIG. 2, which shows the main parts in cross section, a turntable 2 is provided on a base 1. The turntable 2 can be rotated intermittently at approximately 180° angles by a table rotation motor (not shown). A support 3 is vertically fixed on the turntable 2, and a pedestal 4 is horizontally fixed to the upper end of the support 3.

A bearing stand 5 is installed on the pedestal 4.
Two driven shafts 6, 6 are supported symmetrically and rotatably via bearings 7, 7, respectively. The driven shafts 6, 6 are moved by the rotation of the turntable 2 to a winding position on the rear side (on the left side in FIG. 1) and a reel exchange position on the front side (on the right side in FIG. 1). .

A center pin 8, 8 for fitting the center hole R1 of the take-up reel R is provided at the outer end of each driven shaft 6, 6.
are each highlighted.

As shown in FIGS. 3 and 4, the take-up reel R is formed by fixing circular plate-shaped flange plates Rb and Rb to both end surfaces of a cylindrical winding core Ra. Both flange plates Rb and Rb have center holes R1 and Rb on their axes.
R1, and four fitting holes R2 to R2 are formed at approximately equal intervals on the circumference centered on the coaxial center and inward from the winding core Ra. Furthermore, long and narrow opening holes R3 to R3 are formed in both flange plates Rb and Rb, respectively, and are located outside of each of the insertion holes R2 to R2 and extend radially outward from the winding core Ra. It is being Both flange plates Rb,
Rb insertion hole R2~R2 and opening hole R3~R3
are formed symmetrically to each other.

Circular plate-shaped driven side reel flanges 9, 9 are fixed to the outer ends of both driven shafts 6, 6, respectively. On the outer surface of the reel flanges 9, 9,
Engagement pins 10 for fitting into any of the fitting holes R2 of the take-up reel R are protruded, respectively. Therefore, the take-up reel R is supported by the center pin 8 and the engagement pin 10 in a state where it is prevented from rotating on the driven side reel flange 9.

A locking hole 11 is formed in each of the driven side reel flanges 9, 9, and reel locking cylinders 12, 12 are arranged symmetrically on the bearing stand 5. This expansion and contraction of the cylinder 12 causes the locking rod 13 to be engaged with and disengaged from the locking hole 11.

A guide rail 14 is laid on the base 1 behind the turntable 2 in the front-rear direction. A movable base 15 is installed on the guide rail 14 so as to be slidable in the front and rear directions in a horizontal state.

A moving cylinder 16 is installed on the rear end of the base 1 with a telescopic rod 17 directed forward, and the distal end of the telescopic rod 17 is connected to the movable base 15. Therefore, by the expansion and contraction of the moving cylinder 16, the movable base 15 is moved back and forth between the forward position (see the solid line in FIG. 1) and the retreat position (see the two-dot chain line in FIG. 1).

A drive motor 20, which is a winding drive source, is installed via a support bracket 19 at the lower rear side of the stand 18, which stands vertically on the movable base 15. A pulley 21 is fixed to the rotation shaft of the drive motor 20.

A drive shaft 23 is rotatably supported on a bearing stand 22 installed on the stand 18 via bearings 24, 24. This drive shaft 23 is
It is coaxial with the driven shaft 6 at the aforementioned winding position.

Rear end of drive shaft 23 (left end in Figure 1)
a pulley 25 fixed to the drive motor 20;
A transmission belt 26 is hung around the pulley 21 . Therefore, the drive shaft 23 is connected to the drive motor 20
is actively rotated by the drive of the belt drive mechanism.

Front end of drive shaft 23 (right end in FIG. 1)
The driving side reel flange 27 has a circular plate shape.
is fixed. This reel flange 27 is
When the movable base 15 is advanced to the forward position,
The take-up reel R can be held in cooperation with the driven reel flange 9 in the take-up position.

A fitting hole 28 is formed in the front end surface of the drive shaft 23 . The tip of the center pin 8 of the driven reel flange 9 at the winding position is inserted into the fitting hole 28 .

The drive side reel flange 27 is formed with an engagement hole 29 that can be engaged with the tip of the engagement pin 10 of the driven side reel flange 9 at the winding position. By the engagement between the engagement hole 29 and the engagement pin 10,
Both reel flanges 9 and 27 are connected.

Furthermore, on the upper part of the drive side reel flange 27,
A slide hole 30 that can almost match the opening hole R3 of the take-up reel R in the take-up position is opened, and at the upper rear side of the slide hole 30, a starting end holding cylinder 31 moves the telescopic rod 32 downward. It is placed in a oriented position.

A clip 34 is attached to the tip (lower end) of the telescopic rod 32 of the starting end holding cylinder 31 via a mounting bracket 33. The clip 34 is made of a rigid material or a material with appropriate elasticity, and its tip is directed forward through the slide hole 30.
By moving forward and backward, it is possible to move in and out of the take-up reel R at the take-up position through the opening R3. When the starting end holding cylinder 31 is retracted, it is in a standby position, and the clip 34 is moved toward the winding core Ra of the take-up reel R by its extension operation.

Further, the fluid piping of the starting end holding cylinder 31 is as follows because the cylinder 31 is rotated together with the drive side reel flange 27 when the material W is wound up. That is, a well-known rotary joint 35 that is incorporated into a fluid pressure circuit including a fluid pressure source such as pneumatic pressure or oil pressure is disposed behind the pulley 25 of the drive shaft 23, and the rotary joint 35 is attached to the drive shaft 23.
Two hollow holes 36 are provided from 5 to the vicinity of the cylinder 31, and both piping pipes 37, 37 of the cylinder 31 are connected to the open end of each hollow hole 36, respectively.

A locking hole 38 is formed in the drive side reel flange 27, and the bearing stand 2 on the stand 18 is provided with a locking hole 38.
A reel locking cylinder 39 is arranged below the reel 2. The locking rod 40 is engaged with and disengaged from the locking hole 38 by this expansion and contraction operation of the cylinder 39.

Note that the driven side reel flange 9 and the driving side reel flange 27 are set to be always stopped at a predetermined stopping position by a fixed position stopping device consisting of an electrical position detection means and a stopping means (not shown). There is.

In the winding machine described above, in order to wind up the material W forming a line on the take-up reel R, first, the center pin 8 of the driven shaft 6 in the reel exchange position is inserted into the center hole R1.
At the same time, the engaging pin 10 is fitted into the fitting hole R2, and the take-up reel R is attached to the driven side reel flange 9. At this time, the reel flange 9
is the locking rod 13 of the reel locking cylinder 12.
By being engaged with the locking hole 11, rotation is prevented and the position is maintained. Also,
The movable base 15 is in the retracted position, and the clip 3
4 is in a standby position, and the drive motor 20 is in a stopped state. The drive side reel flange 27 is
When the locking rod 40 of the reel locking cylinder 39 is engaged with the locking hole 38, it is prevented from rotating and is in a positioned state.

From this state, the turntable 2 is rotated approximately 180 degrees by a table rotation motor (not shown), and the take-up reel R is moved to the take-up position. As a result, the take-up reel R is moved to the drive side reel flange 27.
The opening hole R3 of the flange plate Rb on the rear side of the take-up reel R is opposed to the clip 34. This opposing relationship between the opening R3 and the clip 34 is achieved by positioning each reel flange 9, 27 by the reel locking cylinders 12, 39.

After that, the moving cylinder 16 is operated to extend,
The movable base 15 is moved to the forward position. As a result, the take-up reel R is held between the driven reel flange 9 and the driving reel flange 27. In this state, the center pin 8
The fitting hole 28 of the drive shaft 23 is fitted into the tip of the drive shaft 23, the tip of the engagement pin 10 is engaged with the engagement hole 29, and the clip 34 is inserted into the flange plate Rb on the rear side of the take-up reel R. Both flange plates through opening hole R3
Intervened between Rb and Rb.

Next, after the starting end of the material W is appropriately inserted between the outside of the winding core Ra of the take-up reel R and the tip of the clip 34, the starting end holding cylinder 31 is operated to extend, and the clip 34 allows the starting end of the material W to be inserted. The starting end is held between the core Ra of the take-up reel R. Thereafter, both the reel locking cylinders 12, 39 are shortened, the locking rods 13, 40 are disengaged from the locking holes 11, 38, and the drive motor 20 is driven. The material W is wound onto the take-up reel R by actively rotating the drive shaft 23 .

Note that during this winding, a new take-up reel R is attached to the driven side reel flange 9 located at the reel exchange position in the same manner as described above.

Thereafter, when the amount of material W wound around both take-up reels R reaches a predetermined amount, the driving of the drive motor 20 is stopped in response to an electric signal emitted from a counter device (not shown), and the winding The rotation of the take-up reel R is stopped. Then, the reel locking cylinders 12 and 39 facing the take-up reel R were extended, and the locking rods 13 and 40 were engaged with the locking holes 11 and 40 of the reel flanges 9 and 27, respectively. After the material W is cut at the end by an appropriate cutter device (not shown), the moving cylinder 16 is shortened and the movable base 15 is moved to the retreat position. As a result, the drive side reel flange 27 is separated from the take-up reel R. Thereafter, the starting end holding cylinder 31 is shortened, and the clip 34 is returned to its original state.

Further, the turntable 2 is reversed, and the take-up reel R on which the material W has been wound is moved to the reel exchange position, and at the same time, a new take-up reel R is moved to the take-up position. Then, the take-up reel R that has taken up the material W is replaced with a new take-up reel R, while the material W is taken up on the take-up reel R that has been moved to the take-up position in the same manner as above. .

By repeating the above steps, the winding of the material W progresses in sequence.

Note that at least two driven shafts 6 are provided on the pedestal 4, and three or four driven shafts are provided as necessary.
Two driven shafts 6 may also be arranged. Further, it is preferable to provide an extrusion device (not shown) on the pedestal 4, which is mainly composed of an extrusion cylinder capable of extruding the take-up reel R.

In addition, reel locking cylinders 12, 12, 39
The reel flanges 9, 9, 27 are prevented from rotating by engaging the respective locking rods 13, 13, 40 in the respective locking holes 11, 11, 38 of the reel flanges 9, 9, 27. However, the locking rods 13, 13, 40 are attached to each reel flange 9, 9,
It is also conceivable to prevent the reel flanges 9, 9, 27 from rotating by abutting the reel flanges 27 with an appropriate pressing force, and to eliminate the locking holes 11, 11, 38. In this case, it is desirable to provide a flange at the tip of each of the locking rods 13, 13, 40 to increase the abutting surface against the reel flange 9, 9, 27.

(Effects of the Invention) In other words, the gist of this invention is the configuration described in the column of "Means for Solving the Problems" mentioned above, and the driven side reel flange to which the take-up reel is attached is driven by the rotation of the turntable. After that, the movable base is moved forward to sandwich the take-up reel between both reel flanges, and the drive-side reel flange is actively rotated by the take-up drive source. Accordingly, while the material is wound on the same take-up reel, the reel is replaced with respect to the driven side reel flange that does not face the driving side reel flange. This has the effect that the time required to replace the take-up reel can be significantly shortened compared to the conventional method, and the efficiency of the take-up work can be improved.

Further, according to the present invention, the winding drive source is not provided on the turntable side but on the movable table side, thereby simplifying the structure of the device itself and rationally achieving the above effects. I can do it.
