Description

[Detailed description of the invention] [Field of industrial application] This invention is a winding machine that winds a continuously supplied strip-shaped material by sequentially switching between a plurality of reels. The present invention relates to a cutting device that cuts a material to be wound.

[Conventional technology]

A winding device that sequentially winds up a plurality of strips (i.e. objects to be wound) such as electrode terminals pressed in a certain pattern by changing the position of the reel, and this reel. There is a winding machine that includes a cutting device that cuts the material to be wound with a shear when changing the position of the material.

By the way, in this type of winding machine, when changing the reel (sometimes every reel, sometimes every few reels), the winding machine is used to inspect whether the press work, etc. has been done accurately. I try to cut out samples of a certain length. However, conventional cutting devices are equipped with only one shear, and the storage box for storing the cut samples is located away from the transport line of the material to be wound.

Figure 5 is a side view of the main parts, and Figure 3 is a time chart, in which guide C that guides the material to be wound to reel B under shear A and storage box D that stores the cut sample are placed side by side. When a certain reel B is aligned with the transfer line and the material to be wound is fully reeled, the shear A is activated to cut it, and then the frame E is moved sideways to the storage box D. At the same time, the feed roller E provided above the shear A was driven to supply the material to be wound, and the shear A was operated again to cut out the sample. When this work was completed, the frame E was returned to its original position, the next reel B was placed on the transfer line, and winding was resumed with this reel B.

[The problem that the idea aims to solve]

Therefore, it takes a considerable amount of time to change the reel, but since the material to be wound is constantly being supplied during this time, the material to be wound is transferred to the press machine, which is a pre-processing machine for this winding machine. If the ring is wrapped around the floor between the floor and other surfaces, it may accumulate and cause scratches. Furthermore, the longer the switching time, the lower the efficiency.

This invention was devised to solve such problems, and its purpose is to develop a cutting device for a winder that can shorten the reel switching time.

[Means to solve the problem]

That is, this invention provides a plurality of reels that move perpendicularly to the conveying direction for the continuously supplied strip-shaped material to be wound.When one reel has fully wound the material to be wound, the next reel is provided. A winding device that moves and winds the reel, and a winding device that is installed on the upper side of the winding device in the transport direction, and when changing the reel, operates a shear to cut the material to be wound, and also operates the shear again. A winding machine comprising a cutting device that cuts a sample of a certain length using a second shear, and a second shear provided above the reel in the supply direction, and a first shear provided above the second shear. A movable guide pipe that moves between a shear and a storage box for storing a sample and a fixed guide pipe that guides the material to be wound to a reel between the second shear and the first shear. The company provided a cutting device for the winder.

[Effect]

From the above, since the storage box that stores the sample and the reel that winds up the material to be wound are both installed on the transfer line, it is only necessary to switch the movable guide pipe that guides the material to be wound between the two. , that time is short. That is, it is incomparably faster than a system in which a storage box and a fixed guide pipe for guiding the material to be wound to the reel are provided in parallel and mechanically slid.

〔Example〕

Hereinafter, embodiments of this invention will be described with reference to the drawings.

Figure 1 is a front view of the winding machine according to this invention, Figure 2
The figure is also a side view, but the winding machine is the cutting device 1.
It is composed of a winding device 2, etc.

A cutting device 1 is used to cut a material to be wound 3 sent from a press machine (not shown) connected to this winding machine.
A supply roller 4 that transfers the material and a shear 5 that cuts the material appropriately.
etc. is becoming more familiar.

The winding device 2 includes a reel 6 for winding up the material to be wound 3, a frame 7 for supporting the reel 6, a base 8 for movably supporting the frame 7, and the like. In these configurations, the frame 7 is movably placed on a rail 9 laid on the base 8 in a direction perpendicular to the direction in which the material to be wound 3 is transported, and the Two reels 6 are loosely fitted onto two main shafts 10 that project in a cantilevered manner in the direction shown in FIG. Furthermore, servo motor 1 is installed on base 8.
The ball screw 12 driven by the rail 9
A nut 13 fixed to the frame 7 is screwed into the ball screw 12, and the frame 7 is thereby moved.

The two reels 6 mounted on both sides of the main shaft 10 are each driven independently by separate drive mechanisms, but here, the main shaft 10 to which a sprocket 15 is fixed, which is driven by a drive motor 14, and Sprocket 17 driven by drive motor 16
The drive sleeve 1 is loosely fitted onto the main shaft 10 and fixed to the drive sleeve 1.
Do this with 8. Both the main shaft 10 and the drive sleeve 18 have drive flanges 19 and 20 at their ends.
are fixed, and drive pins 21 and 22 protruding inward from both flanges 19 and 20, respectively, are connected to the sides of the body 6a of each reel 6, which are loosely fitted onto the main shaft 10 between the drive flanges 19 and 20. drive hole 23,2
Let's move on to 4. Note that the drive flange 19 on the main shaft 10 side slides on the main shaft 10 so that it can be inserted and removed, and is connected to a reel holder 26 that is fixed by a clamp 25. With this, each reel 6 can be attached and removed.

On the other hand, between the objects 3 wound around the reel 6, an interlayer paper reel 27 is installed above the reel 6 to prevent the objects 3 from coming into direct contact with each other and being damaged. The interlayer paper 28 unwound from the paper is sandwiched between the sheets.
Note that when the interlayer paper 28 is fed out, its tension is adjusted by a tension adjustment mechanism 29 in the middle,
The same number of interlayer paper reels 27 as the reels 6 are installed concentrically on the frame 7.

As described above, when the material to be wound 3 is wound around the reel 6 set on the transfer line L and the supply roller 4, drive motor 14, etc. are started, the material to be wound 3 to be fed is wrapped with interlayer paper 28 in between. It is then wound onto the reel 6 (note that there are two rotation directions of the reel 6, clockwise and counterclockwise, and accordingly, the supply position of the material to be wound 3 and the feeding direction of the interlayer paper 28 are changed). different). When the reel 6 completes winding, the shear 5 of the cutting device 2 is activated to cut the material 3 to be wound. Then, the servo motor 11 is driven, moves the frame 7, sets the next reel 6 on the transfer line L, and uses this reel 6 to wind the material 3 again.

By the way, in this invention, the above cutting device 1 is configured as follows. First, two shears 5, a first shear 30 and a second shear 31, are installed along the direction in which the material to be wound 3 is transported. In addition, each shear 30, 31 has an air cylinder 32, 33.
Cutting is performed using the shearing force of movable blades 30a, 31a that are moved by, etc., and fixed blades 30b, 31b that are fixed. Next, a storage box 34 for storing the cut sample of the material to be wound 3 is located near the front position of the second shear 31.
A movable guide pipe 35 for guiding the material to be wound 3 is installed in the transfer path between the two. The movable guide pipe 35 is installed by an air cylinder 36 or the like with the upper inlet serving as a fulcrum, and its outlet 35a is installed between the storage box 34, the second shear 31, and the reel 6, and the material to be wound is 3 to a fixed guide pipe 37 that guides the reel 6 to the reel 6.

FIG. 4 is a time chart showing the operation in this case. When one reel 6 completes winding, the second shear 31 operates and cuts the material 3 at this position. Then, the air cylinder 36
operates, and the outlet 35a of the movable guide pipe 35
is moved to the storage box 34 side. In this state, the first shear 30 operates and cuts the material to be wound 3 at this position, so both ends of the material to be wound 3 are cut off, and these become samples and are passed through the movable guide pipe 35. It is dropped into the storage box 34. During this time, after the second shear 31 finishes its operation, the frame 7 can be moved and the next reel 6 can be moved. Winding can be resumed with the next reel 6.

Looking at this, it can be seen that the switching time of the reel 6 is significantly shortened compared to the conventional system.
That is, the operation of the second shear 31 and the first shear 30 can be switched by simply rotating the movable guide pipe 35 using the air cylinder 36, which can be done in an extremely short time. Further, since the second shear 31 and the first shear 30 are spaced apart, the material to be wound 3 can be supplied even while the movable guide pipe 35 is being switched, and it is necessary to keep the supply roller 4 stopped. One example of this is that there is no such thing. The storage box 34 has two levels, upper and lower, and one of them is selected and used by changing the ejection stroke of the air cylinder 36 that moves the movable guide pipe 35.

[Effect of idea]

As mentioned above, this idea is as follows.
When winding a continuously supplied strip-shaped material by switching the reel one by one and taking out a sample of a certain length at the time of switching, the reel switching time is short and there is no damage to the material to be wound. In addition to not causing any problems, we were able to improve the efficiency of our work.
