Abstract

PURPOSE:To prevent a coiled stock from bending at a coil guide section by sliding the coil guide section back and forth in the parallel direction to the delivery direction and energizing it with a spring member in the opposite direction to the delivery direction. CONSTITUTION:The coiled stock W is loaded sidelong on a turntable 10 and and is sent to the next process through a guide roller 30. The turntable 10 is drived with a servomotor 13a and its velocity is determined by a velocity setting volume 25a. The guide roller 30 is supported and is enabled to slide back and forth by a coil guide mechanism 20. The variation of sliding quantity is detected by a gear 25, the volume 25a is changed and the velocity of the servomotor 13a is changed into the velocity fit the delivery quantity of the coil W. The force of a power spring 41 is conducted to a slider 24 through a pulley 40 and the guide roller 30 is energized with the spring in the opposite direction. Because the impact force given to the coiled stock W is absorbed by the spring member, the bending at the guide section is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a horizontal rotating uncoiler that automatically supplies horizontally stacked coil materials to a press processing line for the next process.

[Prior art]

A horizontal rotating uncoiler is known as an example of a device in a press processing line that supplies coil material to a press machine. As shown in FIG. 6, in this uncoiler, the coil material 1 is stacked horizontally on a turntable 2, and the turntable 2 is intermittently rotated via a limit switch or the like, whereby the coil material 1 is It is intermittently fed out in the direction of arrow A and delivered to a press via a delivery device such as a feed roll. Furthermore, since the turntable 2 rotates intermittently, there is a risk that the unwound coil material 1 may become loose. However, a coil material guide section 4 is provided near the turntable 2 to suspend the unwound coil material 1. The guide portion 4 pulls the coil material 1 in the direction of arrow B, thereby eliminating slack in the unwound coil material. Reference numeral 6 denotes a support portion for the coil material guide portion 4. The guide portion 4 is supported so as to be able to slide in the direction of arrow C, and the gravity of the weight member 7 is always applied to the guide portion 4 via the wire 8. It is supposed to be done. Note that the reference numeral 9 is a pulley.

[Problem to be solved by the invention]

However, in the conventional uncoiler described above, the coil material
When the coil material 1 is a thin plate, there is a problem in that the coil material 1 is bent in the hanging area by the coil material guide portion 4. This is because a tensile force equivalent to the gravity of the weight member 7 is constantly acting on the area suspended by the coil material guide section 4, and when the turntable 2 is stopped intermittently or when the coil material is removed from the press machine side. 1 is pulled, an impact tensile force acts on the coil material at the hanging position in the guide part 4,
It is said that this is the cause of the bending.

The present invention has been made in view of the problems of the prior art,
The purpose is to provide a horizontal revolving uncoiler in which the coil material is not bent at the position where it is hung on the coil material guide section.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the horizontal rotating uncoiler according to the present invention, the coil material stacked horizontally on the turntable is transferred to the processing line for the next process by rotation of the turntable. This is a horizontal type rotating uncoiler that feeds and feeds, and is equipped with a coil material guide section near the turntable to hang the coil material fed out from the turntable and eliminate slack in the coil material to be sent to the next process. The rotary uncoiler supports the coil material guide section so as to be slidable back and forth in a direction substantially parallel to the direction in which the coil material is fed out to the next process, and is spring-loaded by a spring member in a direction opposite to the direction in which the coil material is fed out. It was designed to strengthen the situation.

[Effect]

A spring member supporting the coil material guide portion absorbs an impact force acting on a region of the coil material suspended by the coil material guide portion.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

Figures 1 to 5 show a horizontal rotating uncoiler, in which Figure 1 is a front view of the horizontal rotating uncoiler, Figure 2 is a plan view thereof, and Figure 3 is a part of the coil material guide mechanism. FIG. 4 is a horizontal sectional view thereof, and FIG. 5 is a sectional view taken along the line ■--■ shown in FIG. 3.

In these figures, the reference numeral 10 is a turntable, and this turntable 10 has a pair of leg members 1 installed on the floor.
It is installed on a base 14 having 2. In addition, a cylindrical core 11 is provided at the center of the upper part of the turntable 10.
is erected, and a plurality of coil materials W each having an air core part fitted into the core part 11 are stacked horizontally on the turntable 10 in a stacked state. Furthermore, inside the turntable 10, there is a servo motor 1 that rotationally drives the turntable 10.
A drive section 13 having a drive section 3a is provided inside.

This servo motor 13a rotates at a rotational speed according to a signal from a speed setting volume 25a, which will be described later, to feed out the coil material W.

Further, a support post 16 is erected at one end of the base 14, and a coil material guide mechanism 20 having a guide roller 30 serving as a coil material guide portion is supported by this support post 16. The pillar 16 is.

The inner cylinder part 16a has a concentric inner and outer cylinder structure, and
The column 16 is urged in the direction of extension by a compression coil spring 17 against the outer cylinder portion 16b, and the amount of extension, that is, the height of the column 16 can be adjusted by a locking mechanism (not shown). The height position of a certain guide roller 30 can be adjusted.

Reference numeral 21 indicates a rectangular casing of the coil material guide mechanism 20, reference numeral 21a a cover, reference numeral 21b a side wall, and reference numeral 2.
1c is a bottom plate. Inside the casing 21, a main rail 22A and a sub-rail 22B are disposed which are fixedly supported at both ends by the side walls 21b, 21b, and which vertically face each other and extend in the horizontal direction. A slider 24 is attached to the rail 22A via a roller ball bearing 23A, and a roller 2313 provided on the slider 24 is attached to the subrail 22.
It is designed to roll along B. Casing 21
A rack 26 extending parallel to the rail 22 is provided on the bottom plate 21A of the
A gear 25 is disposed and supported on the side of the slider 24.
is engaged with this rack 26, allowing the slider 24 to slide smoothly along the rail 22A. Further, on the side surface of the slider 24 opposite to the gear 25 support part, an L-shaped shaft 28 that extends downward perpendicularly to the rail 22A is protruded, and a coil material W is hung on the tip of the shaft 28. A supporting roller 30 is rotatably assembled. Reference numeral 28a in FIG. 4 indicates the shaft 28.
This is the part that is fixed to the slider 24. Reference numeral 32 indicates a disk-shaped work guide formed at both ends of the guide roller 30 for positioning the coil material W in the width direction, and reference numeral 34 indicates the guide roller 30 of the coil material W.
This is a guide bar to prevent it from falling off. Further, a joint portion 29 is provided at the L-shaped bent portion of the shaft 28, and the bent shape of the shaft 28 can be adjusted so that the direction of the guide roller 30 is at the best position with respect to the coil material W at the position of the joint portion 29. It looks like this.

Reference numeral 25a denotes a speed setting volume that detects the amount of rotation of the gear 25 and outputs a signal according to the amount of rotation, in other words, the position of the slider 24.

The servo motor 13a of the drive unit 13 of the turntable rotates at a speed corresponding to this output. That is, if the rotation of the turntable 10 is slow and the amount of coil material W to be fed out is insufficient compared to the coil material delivery speed of a single eed roll, for example, the coil material W is in a tensioned state and the guide roller 3
0 is pulled, and the slider 24 slides to the right in FIG. At this time, the speed setting volume 25a outputs a signal proportional to the amount of rotation of the gear 25, the rotational speed of the servo motor 13a increases, and the speed at which the coil material W is fed out from the turntable 10 increases.

On the other hand, when the turntable 10 rotates quickly and the coil material W becomes slack, the tension acting on the guide roller 30 becomes weaker and the slider 24 slides to the left in FIG. 3. Then, the speed setting volume 25a outputs a signal proportional to the amount of rotation of the gear 25, the rotational speed of the servo motor 13a is slowed down, and the speed at which the coil material W is fed out from the turntable 10 is reduced.

Reference numeral 40 denotes a pulley which is urged to rotate by a built-in mainspring spring 41. This pulley 40 is connected to the slider 24 via a wire 42, and the slider 24 is connected to the third
It is in a state where it is constantly pulled to the left in Figures 4 and 4.

Therefore, the slider 24 and the guide roller 30 are always biased toward the left in FIG. 3 by the spring force of the mainspring spring 41. Note that the spring force of the mainspring spring 41 can be adjusted using an adjustment screw 43. The coil material W is hung on this guide roller 30 and sent out in the direction of arrow A, and the hanging portion of the coil material W is always provided with a direction in which the coil material is sent out to the next process (for example, a feed roll). A force in the opposite direction (same direction as the direction in which the coil material is fed out due to the rotation of the turntable 10) acts to eliminate slack in the coil material W.

In addition, when the tensile force of the press is applied to the coil material, or at the moment when the rotation of the turntable 10 stops and the feeding of the coil material stops, the tensile force from the next process (for example, the feed roll) or the guide The inertial force of the coil material in the area in front of the roller is doubled and acts as an impact force on the guide roller 30 suspending the coil material. However, when these forces act on the guide roller 30, the mainspring spring 41 deforms and absorbs this impact force. Therefore, the coil material W
The wI impact force acting on the hanging area is significantly reduced and transmitted to the guide roller 30 side. Therefore, a large impact tensile force does not act between the coil material W and the guide roller 30, and problems such as the coil material W being bent and broken in the area where the coil material W is suspended by the guide roller 30 are avoided. There is no.

〔Effect of the invention〕

As is clear from the above description, in the horizontal rotating uncoiler according to the present invention, the spring member supporting the coil material guide absorbs the impact force acting on the area suspended by the coil material guide. This eliminates bending in the area where the coil material is hung over the guide portion, allowing stable use over a long period of time.
