DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for winding a belt-shaped material such as a tire material onto a reel.

[0002]

2. Description of the Related Art Tire constituent materials made of unvulcanized rubber formed by extrusion molding (such as sidewalls,
Hereinafter, the "soft band material" is temporarily wound around a reel for transport to the next step or for temporary stocking. In order to prevent inseparable adhesion, a liner made of a politics or the like is wound together. Conventionally, this kind of winding operation is performed as follows.

That is, an empty reel is carried into and set in a reel rotating device, and a soft strip supplied from an extruder or the like is pulled out to a reel position while being held in a hand. Then, the reel is rotated several times by hand while the front end portion of the soft strip material is applied to the outer peripheral surface of the reel cylinder. As a result, preparation for winding the soft band material is completed. Next, the reel rotating device is driven to perform continuous winding. After the rotation device is stopped by the end of winding, the operator cuts the soft band using scissors, and the tail end generated by this cutting is wound around the soft band wound on the reel. Press lightly on the surface.

Then, the actual reel is carried out.

[0005]

Most of the above-mentioned winding operations, except for the continuous winding operation by a reel rotating device, are manually performed manually. For this reason, it is inefficient and, depending on the operator, there are problems such as crushing or breaking at the tip or tail end of the soft band material, or wrinkling particularly at the liner or the like. For this reason, there is a case where waste occurs in the soft band material. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and achieves high efficiency in the winding operation of a soft band material, and winding of a soft band material capable of preventing waste of the soft band material. It is intended to provide a device.

After that, if continuous winding work is performed,
Good. The introduction forcing part is supplied in a hanging state from above.
The compressed air is blown to the tip of the soft strip.
By doing this,
It is not necessary to provide a member that comes into contact with the soft band material.
Therefore, there is a possibility that the soft band-shaped material may be scratched or deformed.
This is advantageous in simplifying the structure.

[0009] In the winding device for a soft strip according to the present invention,
The supply path of the soft band material to the reel ,
A tension adjusting device having a dancer roller having a variable degree of contact with the soft band material in accordance with excess or deficiency of the tension, and a feed driver capable of coming into contact with and separating from the soft band material; and An auxiliary feeder is provided which enables the dancer roller of the tension adjusting device to be pushed back to its inoperative position by contact. In the tension adjusting device, when the soft strip material is continuously wound on the reel, the tension is kept constant in the supply state of the soft strip material.

On the other hand, in the auxiliary feeding device, the feed driving body is brought into contact with the soft band material as required, and at this time, the dancer roller of the tension adjusting device is pushed back to the inoperative position. . That is, this makes it possible to deactivate the tension adjusting device (prevent the tension control from being performed). In addition, while the feed driver is in contact with the soft strip, the feed driver can feed the soft strip. For this reason, by setting the auxiliary feeding device in an operating state (a state in which the feed driving body is in contact with the soft strip), the supply speed of the soft strip is affected by excess or deficiency of the tension. And can be kept constant. Therefore, if the auxiliary feeding device is temporarily operated at the start of the winding operation, the winding of the soft band material around the reel can be ensured, and waste can be prevented from being generated at the tip of the soft band material. In addition, if the auxiliary feeder is temporarily operated just before the end of the winding operation, it is possible to accurately determine the cutting position in the soft strip, and to prevent waste at the tail end of the soft strip. .

In addition, as a feed driving body of the auxiliary feeding device, a swing fulcrum is arranged at a position upstream of the dancer roller of the tension adjusting device, and a swing that can be brought into contact with and separated from the soft strip material on the downstream side is possible. It can be constituted by the driving conveyor described above. By employing such a configuration, the structure can be simplified. Winding of a soft strip according to the present invention
In the apparatus, a cutting section for cutting the soft strip material and a tail end generated by the cutting are formed along a supply path of the soft strip material to the reel along a winding outer peripheral surface of the soft strip material wound on the reel. And a tail end processing unit that guides the transfer in a shape.

The cutting section cuts the soft strip into a predetermined length when the winding of the soft strip on the reel is completed, and the tail end processing section cuts the soft strip formed by the cutting. The tail end of the material is gently transferred to the winding outer surface of the soft band material wound on the reel, and guided along the surface. For this reason, a clean cut surface can be obtained, and there is no possibility that the tail end portion of the soft band-shaped material is damaged or deformed. In addition, since the generation of scrap can be suppressed, the generation of waste in the soft strip can be prevented.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view showing a winding device 1 according to an embodiment of the present invention.
Is a winding work section that can hold and rotate
Reference numeral 3 denotes a supply path for supplying the soft band material W to the winding work unit 2. The winding device 1 is configured to be capable of winding the soft band material W on two reels R in parallel, as is apparent from FIG.

As shown in FIG. 2, the reel R has a hollow winding drum Dr formed to be slightly wider than the soft strip material W.
And flange portions F provided on both sides of the winding drum Dr. The flange portion F is preferably formed so as to have a diameter larger than the outer diameter when the soft band material W is completely wound around the winding drum Dr. First, the winding operation unit 2 will be described. The take-up section 2 includes a reel receiving section 4 for holding a reel R, a reel damping section 5 provided to be able to enter and exit the area above the reel receiving section 4, and a reel receiving section 4. An initial winding portion 6 provided so as to be able to approach / separate from the side of the upper reel R;

The reel receiving portion 4 has a total of four bearings so as to support two circumferential portions (see FIG. 1) of both flange portions F (see FIG. 2) with respect to one reel R. It has a roller 4a. An appropriate number of the bearing rollers 4a can be driven and rotated by the motor 9. It is preferable that the motor 9 be provided with an electromagnetic brake, a speed reducer, or the like, and that the rotation speed be controlled with high accuracy. As shown in FIG. 3, the reel damping portion 5 is in contact with the reel R on the reel receiving portion 4 at the top of the flange portion F so as to urge the reel R downward. 5a and a moving mechanism section 12 for moving the pressing roller 5a inside and outside the operation area.

The pressing rollers 5a are also provided in a total of four for one reel R so as to correspond to two circumferential portions of both flange portions F (see FIG. 4). Each of these pressing rollers 5a is rotatable. The moving mechanism unit 12 is provided with each pressing roller 5.

The oscillating frame 13 is oscillatingly driven by a driving tool 20 such as a fluid pressure cylinder held by an elevating frame 14, and the elevating frame 14 is suspended from a bracket 21 provided on a slide base frame 16. Driver 2 such as a fluid pressure cylinder
The slide base frame 16 is horizontally moved by an appropriate driving means such as a chain transmission means or the like, though not shown, although the slide base frame 16 is driven up and down (see FIGS. 3 and 5). The standby state of the moving mechanism unit 12 is such that the slide base frame 16 moves away from the region above the winding work unit 2 to the side (front side or back side in FIG. 1), and the swing frame 13 moves to the swing upper position. The frame 14 jumps up and the lifting frame 14 is raised. And
From this standby state, horizontal movement toward the winding work unit 2 by the slide base frame 16, swinging down to the swinging down position by the swinging frame 13, and lowering by the lifting frame 14 are performed in this order, and pushing down. The roller 5a is brought into contact with the reel R on the reel receiving portion 4.

As shown in FIG. 1, the initial winding section 6 and the introduction forcing section 7 are mounted on a bogie 25 traveling between the side of the winding work section 2 and the separated position. It is provided via a slide body 26. Therefore, high-precision positioning with respect to the winding work unit 2 is enabled by the movement of the slide body 26 on the carriage 25. In addition, in order to secure a work area necessary for manual winding when a trouble occurs, the carriage 25 can be moved by attaching a moving rail and wheels. As shown in FIG. 6, the initial winding portion 6 includes a plurality of fixed pulleys 28 disposed at appropriate locations in the slide body 26, and movable pulleys 29, 30, which are provided at appropriate locations on the outer peripheral portion of the slide body 26. 31 and an endless belt 32 extending around these pulleys.

The adjacent belt 32 is formed to have a width (the same dimensional relationship as that of the soft strip W shown in FIG. 2) in which the two flange portions F of the reel R enter each other.
In the moving pulley, a position facing the winding work unit 2 (FIG. 6)
Upper and lower moving pulleys 29, 30 arranged on the right side)
Is for winding the adjacent belt 32 wound between them around the winding drum Dr of the reel R. In addition, a position away from the winding work unit 2 (the left side in FIG. 6).
Is used for adjusting the tension of the adjacent belt 32.

That is, the upper winding moving pulley 2
Two pulleys 9 are held in parallel by a pulley bracket 35 so as to abut against two places in the circumferential direction with respect to the winding drum Dr of the reel R. And this pulley bracket 35
It is provided so as to be vertically moved between a retracted position above the winding drum Dr and an upper contact position with the winding drum Dr by a driving tool 36 such as a fluid pressure cylinder. Further, the lower winding moving pulley 30 is held by a pulley arm 38 that swings about a fulcrum shaft 37 positioned below the winding drum Dr of the reel R. The pulley arm 38 is provided so as to move up and down between a retracted position in front of the winding drum Dr and a lower contact position with the winding drum Dr by a driving tool 39 such as a fluid pressure cylinder.

The movable pulley 31 for adjusting the tension can be moved up and down by a driving tool 40 such as a fluid pressure cylinder.
41 is a guide member for guiding the lifting and lowering of the pulley bracket 42. The moving pulley 31 lowers the pulley bracket 42 as the contact belt 32 extending between the upper and lower moving pulleys 29 and 30 abuts on the winding drum Dr of the reel R. Attached belt 3
2 provides a marginal length for winding the winding belt Dr around the winding belt Dr while keeping the predetermined tension at 2 to prevent the belt 2 from coming off.

Needless to say, in the standby state in the initial winding section 6, the slide body 26 is retracted from the winding work section 2, the upper moving pulley 29 is raised, and the lower moving pulley 30 is moved to the swinging lower position. Moving pulley 3 for tension adjustment
1 is in an elevated state. And from this state, trolley 2
5 and proximity to the winding work unit 2 and the slide body 26
Is performed, the contact belt 32 between the upper and lower movable pulleys 29 and 30 abuts on the winding drum Dr of the reel R. At this time, as described above, the tension-adjusting moving pulley 31 also descends synchronously. Then, the lowering of the upper moving pulley 29 and the lower moving pulley 30
Is moved to the swinging upper position, the side-by-side belt 32 is wound around the winding drum Dr of the reel R by about 3/4 of a turn.

As a result, a provisional guide path 44 for introducing the soft strip W is formed between the winding drum Dr and the adjacent belt 32. In addition, as the reel R on the winding work unit 2 is rotated, the adjacent belt 32 is tuned by receiving frictional transmission with the winding drum Dr or the soft band material W introduced into the provisional guide path 44. It is designed to run cyclically. The introduction forcing section 7 has a driving tool 48 such as a fluid pressure cylinder provided on the leading end side of the pulley arm 38 via a bracket 46, and an ejection nozzle 47 which is vertically moved by the driving tool 48. Spout nozzle 4
7 is connected to a supply device for compressed air and a control valve (both not shown) so that the compressed air is blown toward the inlet of the provisional guideway 44 when it is raised by the driving tool 48. Has become.

For this reason, when the initial winding portion 6 forms the provisional guide path 44 (when the pulley arm 38 moves to the swinging upper position), the vertical movement driving tool 48 is moved in the introduction forcing portion 7. The ejection nozzle 47 is raised, and compressed air is blown from above to the tip of the soft strip W supplied in a hanging state. Thereby, the soft belt-shaped material W is reliably guided to the provisional guideway 44. Next, the supply path 3 for the soft band material W will be described. As shown in FIG. 1, in the supply path 3, a material transport device 50, an auxiliary feed device 51 following the material transport device 50, a tension adjusting device 52 provided along with the auxiliary feed device 51, A cutting section 53 provided below the device 52 and a tail end processing section 54 provided in parallel with the cutting section 53 are provided.

As shown in FIG. 7, the material conveying device 50 includes a free conveyor 58 provided for an upper beam 56 constituting an overall device frame as a winding device, and a downstream side from the free conveyor 58. It has a pair of pinch rollers 59 provided at a predetermined distance (the working space of the auxiliary feeder 51). The free conveyor 58 has an endless flat belt 61 stretched between a pair of rollers 60, and is literally non-driven. This flat belt 61
Has a width dimension capable of receiving two soft strips W in a state of being arranged side by side.

The pair of pinch rollers 59 includes upper and lower rollers 59.
The soft belt-shaped material W can be drawn out between the members a and 59b. For example, the lower roller 59b may be rotationally driven by a motor (not shown). Auxiliary feeder 51
Is a feed driving body 63 held so that the roller shaft on the downstream side (the left side in FIG. 7) of the free conveyor 58 is a swing fulcrum 60a, and a fluid pressure cylinder that swings and drives the feed drive body 63 And the like.

A driving conveyor is used for the feed driving body 63. That is, a pair of rollers 66 are held at a predetermined interval with respect to the conveyor frame 65, and these rollers 6
An endless flat belt 67 is stretched between the six belts. The flat belt 67 has the same width as the flat belt 61 of the material conveying device 50. The conveyor frame 65 is provided with a swing lever 68 projecting obliquely downward, and the protruding end of the swing lever 68 is connected to the driving tool 64. Therefore, this auxiliary feeder 51 is
By the operation of 4, it is possible to switch between a transport state in which the material transport apparatus 50 is flush with the material transport apparatus 50 and a retracted state in which the transport state is separated downward.

The tension adjusting device 52 includes a dancer roller 72 that is vertically swingable with the roller shaft of the upper roller 59a in the pinch roller pair 59 as a swing fulcrum 71. When the feed driver 63 of the auxiliary feeder 51 is retracted downward as shown by a two-dot chain line in FIG. 7, the dancer roller 72 is connected to the free conveyor 58 and the pinch roller pair 59 of the material transfer device 50. Will be able to swing down between each other. Therefore, the load of the dancer roller 72 is applied to the soft band material W passing through this portion, and thereby control is performed to eliminate the excess and deficiency of the tension.

When the feed driving body 63 is set in the upper conveying state, the dancer roller 72 is pushed upward in accordance with this, and as a result, as a result, the tension adjusting device 5
2 will be maintained in an inoperative state. It should be noted that the tension of the soft strip W can be adjusted by mechanically controlling the vertical movement of the dancer roller 72. In the material conveying device 50, the pinch roller pair 59 is connected to the feed driving body 6 of the auxiliary feeding device 51.
In a case where the upper roller 59a moves upward and the dancer roller 72 of the tension adjusting device 52 is made inoperative, the upper roller 59a also floats (that is, the soft belt-shaped material W is not sandwiched). It is also possible. That is, when the feed driving body 63 feeds the soft belt-shaped material W, the feeding by the pinch roller pair 59 is not affected, and the driving by the feed driving body 63 alone can be controlled.

As shown in FIG. 1, the cutting section 53 and the tail end processing section 54 are provided with a pair of pinch rollers 59 of the material conveying device 50.
Is provided at a lower portion corresponding to a hanging frame 75 vertically provided from the upper beam 56. As shown in FIGS. 8 to 10, a unit board 77 is held by the hanging frame 75 via a vertical guide rail 76 so as to be vertically movable. The unit substrate 77 is provided with a driving tool 7 such as a fluid pressure cylinder provided for the upper beam 56 and the like.
8 drives it up and down.

Then, the cutting section 53 and the tail end processing section 54
Are provided for the unit substrate 77. Accordingly, the whole of these members moves up and down together by the operation of the driving tool 78. As will be described later, the vertical movement of the cutting unit 53 is mainly for retreating when not in operation, and the tail end processing unit 54 is a part of the work. The cutting section 53 includes a slide-type cutter device 80 and a material pressing device 8 provided below the cutter device 80.
And 1.

In the cutter device 80, an appropriate cutting tool 84 (see FIG. 9) such as a cutter blade is attached to a cutter holder 83 which is slidably held along a guide rail 82 which is installed substantially horizontally. The cutter holder 83 is configured to be able to travel by a driving tool 85 such as a rodless cylinder. In addition, as the cutting tool 84, a configuration in which a heat cutter, a rotary blade, or the like can be used is also possible. The material pressing device 81 presses the pressing piece 86 by a driving tool 87 such as a fluid pressure cylinder or the like to a unit substrate 77 (a portion of the soft strip W that has passed through the cutter device 80).
It is configured to be pressed against. Thus, it goes without saying that the cutting operation with the cutter device 80 can be performed easily and neatly.

The pressing piece 86 is preferably made of a material having a certain buffering action, such as a bag filled with air or water, in addition to rubber and soft resin. It is also possible to form by such as. Tail end processing unit 54
9 is a side view J-shaped swing frame 89 suspended from the unit board 77 so as to be able to swing back and forth, and a driving tool 90 such as a fluid pressure cylinder for swinging the swing frame 89 (FIGS. 9 and 9). 10), a take-up roller 91 rotatably held on an upper side of a lower horizontal rail 89a of a swing frame 89, and a rotatable corresponding to the take-up roller 91 at a lower side of the lower horizontal rail 89a. And a held winding roller 92.

The material for forming the take-in roller 91 is not particularly limited. It is preferable to form by such as. The tail end processing unit 54 sets a state in which the take-in roller 91 does not protrude too much (a solid line state) as shown in FIG. 9 with respect to the upright surface on the side of the unit substrate 77 on which the cutter device 80 and the like are provided. A state in which the take-in roller 91 protrudes greatly from this state and comes close to the material pressing device 81 (a two-dot chain line state) is defined as an operating state. Further, the unit substrate 77 is usually located at the lower end, and when the take-up cart (reel receiving unit 4) is traversed,
When the reel damping unit 5 is lowered, it is raised only in that case in order to prevent interference with the cutter unit.

The operation of the tail end processing section 54 (including the lowering of the unit substrate 77) includes the cutting operation by the cutter device 80 and the release of the soft strip material W by the material pressing device 81 in the cutting section 53. Immediately after being performed, it is to be executed. Therefore, the tail end (cut portion) of the soft strip material W generated at the cutting portion 53 can be easily and reliably peeled off from the unit substrate 77 by the take-in roller 91, and thereafter, by the winding roller 92. , The soft strip W wound on the reel R
Is gently transferred and guided to the outer peripheral surface of the winding, and is brought into contact with the body by receiving an appropriate pressing action.

Next, a series of operating states of the entire winding device will be described. First, the standby state of the winding device is shown in FIG.
As shown in the figure, the feed driving body 63 of the auxiliary feeder 51 is set in the upper conveying state in the supply path 3 of the soft strip material W,
In addition to the state where the dancer roller 72 of the tension adjusting device 52 is in the inoperative state, the cutting section 53, the reel damping section 5, the initial winding section 6, the introduction forcing section 7, etc. are retracted from the winding operation section 2. Has become. When an empty reel R is carried into the winding work unit 2, the reel damping unit 5 moves to the lower swing position and urges the reel R to the reel receiving unit 4 as shown in FIG. . Then, the reel receiving section 4 starts the rotation of the reel R.

Next, in the initial winding section 6, the slide body 26 approaches the winding work section 2, and the adjacent belt 32 is wound around the winding drum Dr of the reel R.
Thereby, the provisional guide path 44 is formed around the winding drum Dr. In this state, the material conveying device 50 of the supply path 3 and the feed driving body 63 of the auxiliary feeding device 51 (at this time, still in the upper conveying state shown in FIG. 1) feed the soft strip material W. To start. When the front end of the soft strip W reaches the entrance of the provisional guideway 44, compressed air is ejected from the ejection nozzle 47 in the introduction forcing section 7. Therefore, the soft belt-shaped material W is reliably and quickly introduced into the provisional guideway 44. The position of the distal end of the soft strip material W can be detected by, for example, providing a yard meter or the like (not shown) at an appropriate position in the supply path 3 and counting.

When the soft belt-shaped material W is wound around the winding drum Dr of the reel R for about three turns in this way, the feed driving body 63 of the auxiliary feeder 51 moves to the retracted state below, thereby adjusting the tension. The dancer roller 72 of the device 52 is swung down. Therefore, the tension control for the soft strip W passing through this portion is started. Then, the operations of the initial winding unit 6 and the introduction forcing unit 7 are stopped, and the returning operation is performed. In addition, as shown in FIG. 12, the carriage 25 and the slide body 26 separate from the winding operation unit 2. Thereby, the provisional taxiway 44 is released.

Further, the reel damping unit 5 retreats to the upper swing position, and the reel receiving unit 4 continues to rotate the reel R. Thereby, the automatic winding of the continuous soft strip W on the reel R is performed. At this time, the rotation speed of the reel R in the reel receiving section 4 can be increased. Next, when the winding amount of the soft band material W reaches a predetermined value (detected by the above-described yard meter or the like), the reel receiving portion 4 stops the rotation of the reel R, and the material transport device 5
At 0, the feeding of the soft band material W is stopped.

Further, in the supply path 3 of the soft strip material W, the feed driving body 63 of the auxiliary feeding device 51 moves to the upper conveying state, and the dancer roller 72 of the tension adjusting device 52 is made inoperative. Next, the unit substrate 77 including the cutting section 53 and the tail end processing section 54 is lowered. And the cutting section 53
In the process, the pressing of the soft band material W by the material pressing device 81 (see FIGS. 8 and 9) and the cutting by the cutter device 80 are performed. Further, when the material pressing device 81 releases the pressing of the soft band material W after the cutting operation is completed, the tail end processing section 54 starts operating, and the tail end portion of the soft band material W is removed from the soft band material wound on the reel R. The transfer is gently guided on the winding outer peripheral surface of the band-shaped material W. At this time, the material transport device 50 and the auxiliary feed device 5
The one feed driver 63 gives the soft strip material W an appropriate feed synchronized with the tail end processing unit 54.

Thereafter, the tail end processing unit 54 appropriately presses the tail end of the soft belt-shaped material W on the reel R with respect to the wound outer peripheral surface thereof so as to be in a state of being in contact therewith. Thereafter, the return movement of the tail end processing unit 54, the lifting of the unit substrate 77, and the return movement of each unit in the cutting unit 53 are performed. Finally, the actual reel R whose winding has been completed is carried out, and is again taken up by the winding work unit 2.
, An empty reel R is carried in and set. Thereafter, these series of operations are repeated. The loading and setting of the empty reel R and the unloading of the actual reel R may be performed by a crane device, an appropriate unloading device, an unloading conveyor, an unloading robot, a forklift, or the like.

The present invention is not limited to the above embodiment. For example, the soft band-shaped material W is not limited at all in terms of the material and shape thereof, the material of the liner and the presence or absence thereof. Further, the structure, mechanism, driving tool, and the like of each detail can be replaced with conventionally known various mechanisms and devices.
