Description

Detailed Description of the Invention The present invention has a sheet winding position and a sheet roll take-out position, a winding shaft is supported at both ends by opposing support parts of a movable machine frame, and the winding shaft is centrally driven. The present invention relates to a sheet winding machine that winds up a sheet.

Conventionally, in this type of sheet winding machine, when taking out the sheet roll wound on the winding shaft, there are two methods:
Alternatively, the sheet roll is pulled out of the machine by turning one end of the take-up shaft 15 to 25 degrees to the side (Japanese Patent Application Laid-Open No. 1987-
141343) etc. are used.

However, in the case of the former method, the take-up shaft and sheet roll are taken out of the machine in an integrated state, and then the take-up shaft is pulled out using a special device, which is a time-consuming process. , and it is difficult to automate the work, and in order to increase efficiency, it is necessary to prepare a spare winding shaft, and in the case of the latter method, the horizontal direction of the winding shaft is fixed to the movable machine frame. The mechanism becomes extremely complicated due to the provision of a rotating mechanism and the like.

On the other hand, the present applicant has published Japanese Patent Application Laid-Open No. 57-141342,
In a sheet winding machine in which the sheet winding position and the sheet roll take-out position are the same, a device is proposed in which the sheet roll is supported from below by a carry-out holder at that position where the sheet roll is wound up, and the winding shaft is pulled out as it is. However, in the case of a sheet winding machine in which the winding shaft is supported by a movable machine frame, the movable machine frame reciprocates between the sheet winding position and the sheet roll take-out position, and compared to a fixed machine frame, Mechanically, its size is limited to a small size, so it is difficult to attach a mechanism to pull out and return the winding shaft directly to the machine frame, and if it is attached, it may get in the way when moving. . In particular, in the case of a so-called turret type winder, in addition to the sheet winding position and the sheet roll take-out position, there are multiple winding shaft standby positions, etc., and the winding shaft is arranged at each of these positions. It is practically impossible to install a mechanism for individually pulling out and returning the winding shaft to all the corresponding positions on the movable machine frame. Therefore, the above proposal cannot be applied to a sheet winding machine in which the sheet winding position and the sheet roll take-out position are different.

Therefore, the present invention was developed to solve the above-mentioned problems, and provides a way to apply a take-up shaft pull-out and return mechanism to a sheet winder having a different sheet winding position and sheet roll take-out position. It is open.

Hereinafter, the configuration and embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an overall example of a winding machine 1 and a sheet roll delivery vehicle 2 to which the present invention is applied. The sheet S is pulled out from the original fabric 10, divided into several strips by a slitter 11, distributed into upper and lower sections, and wound onto a winding shaft 13 via a touch roller 12, respectively. The winding shaft 13 is a pair of well-known rotating machine frames (turret plates).
The touch roller 1 is supported between 14 and 14'.
In this example, it is possible to move from the winding position A adjacent to the winding position A to the take-out position B on the opposite side. Figure 1 shows a sheet roll R that has just been wound up being moved to the take-out position B, and the winding shaft 13, which was waiting at the take-out position B with a new core installed, moved to the winding position A and before starting new winding. Indicates the status of If the winding and unloading positions are separated in this way, it is possible to take out the sheet roll R and install a new core during winding.

Winding shaft support portions 16, 1 of rotating machine frames 14, 14'
5 and the shaft extraction mechanism 17 are shown in FIGS. 2-4. The main parts in this embodiment include a sheet winding position A and a sheet roll take-out position B, and the opposing support parts 1 of the movable machine frames (swivel machine frames) 14 and 14'.
In the sheet winding machine 1 which supports the winding shaft 13 at both ends by 6 and 15 and winds the sheet by centrally driving the winding shaft 13, the support portion 16 of the rotating machine frame 14
a bearing sleeve 19 that is removably fitted into the winding shaft 13 and that supports one end of the winding shaft 13 irremovably;
A pull-out fitting 20 that enters into the interior from the outer end of the roll and cannot escape, and presses the end of the winding shaft 13 directly and elastically, and is capable of engaging and disengaging with the pull-out fitting 20 at the sheet roll take-out position B. is provided, and when the sheet roll is taken out, it engages with the extraction fitting 20 and extracts both the bearing cylinder 19 and the winding shaft 13 in the axial direction, leaving the wound sheet roll R on the carrying-out holder 2a,
Thereafter, the shaft pull-out return mechanism 17 returns the take-up shaft and separates from the pull-out fitting 20, and the rotating machine frame 1
A restraining mechanism 21 is provided on the supporting portion 15 of the movable machine frame 14', and is provided on the support portion 15 of the movable machine frame 14', and prevents the take-up shaft 13 from escaping through the pull-out fitting 20 except when the take-up shaft is being pulled out. The drive shaft 23 supports the other end of the drive shaft 13 so as to be engageable and detachable, and rotates the drive shaft 23.

The rotating machine frames 14, 14 are commonly called turret disks, and are supported and driven by the main machine frame 1a of the winding machine 1 so as to face each other and rotate together. 2 and 3 show a cross section of only the vicinity of the winding shaft support portions 15 and 16 of the rotating machine frames 14' and 14, although the description thereof will be omitted since it is well known. A large-diameter gear 14a for turning drive is attached to the outer circumferential side.

In this case, the support section 15 shown in FIG. 2 has a drive mechanism that engages the end of the winding shaft 13 so as to be able to approach and separate it, and rotationally drives it. That is, the support part 15 horizontally passes through the rotating machine frame 14', and a winding drive shaft 23 is fitted in a fixed bearing 22, and a magnetic particle clutch 24 attached to an extension of the bearing 22 is attached.
The drive shaft 23 is rotationally driven by a drive motor (not shown) via the input gear 25, and a gear 26 and a pulley 27 loosely engaged with the rotation center shaft 44 of the machine frame 14'.

A cylindrical tooth clutch 28 and a conical portion 29 for supporting the winding shaft protrude from the center of the tooth clutch 28 at the tip (left end in FIG. 2) of the drive shaft 23. When the winding shaft 13 is pressed, the conical portion 29 is inserted into the conical hole in the end surface of the shaft.
enters, and tooth clutches 28 on both end faces of the winding shaft and drive shaft engage.

The support portion 16 shown in FIG. 3 supports the winding shaft 13 so that it can be pulled out. Therefore, the shaft end of the winding shaft 13 is made slightly thinner, and a bearing sleeve 19 having an outer diameter approximately the same as that of the winding shaft 13 is fitted therein. This is a unique configuration in which the winding shaft 13 is pulled out while the bearing sleeve 19 is fitted. Therefore, the resin sleeves 30 and 31 on the rotating machine frame 14 side that support this bearing sleeve 19 have the same inner diameter as the sleeve 32 for the winding shaft 13, and all support the winding shaft 13 when the shaft is removed. It turns out.

In addition to the function of bearing the winding shaft 13, the bearing cylinder 19 also has the function of holding the shaft when it is taken out or returned. The height of the seats of the four ball or roller bearings 33 makes it impossible to separate the shaft 13 and the bearing sleeve 19. the bearing 3
The tip of the extraction fitting 20 is inserted into the inside of the outer end side where there is no 3.

The extraction fitting 20 has a flange 34 on which the hook of the shaft extraction mechanism 17 is hung, a flange 35 on which the clamp head of the restraining mechanism 21 is hung, and a stopper tube 37 attached to the inner wall of the bearing sleeve 19 at the tip of the metal fitting 20 in order to make it impossible to escape. It has a screwed collar 36. In addition, a coil spring 38 and a pressure rod 39 are inserted into the center hole of the front end surface of the extraction fitting 20, and the bearing cylinder 19 and the pressure rod 39 are inserted through the contact plate 40.
The winding shaft 13 is elastically pressurized.

After the winding shaft 13 is pulled out and the two rolled up sheet rolls R are placed on the carrying-out holder 2a as shown in FIG. 5 and carried out, the winding shaft 13 is immediately returned to its original position. At the time of extraction, the clamp head 21a of the restraining mechanism 21, which had been retracted to the chain line position, returns to the solid line position in FIG. It is pressed and fixed onto the mechanism 18 and the tooth clutch 24 is connected. The above-mentioned restraining mechanism 21 is a commercially available product, and is advantageous because it is of a type that does not move the clamp head 21a straight forward using fluid pressure, but moves it a little upward and then holds it down.

The shaft pull-out return mechanism 17 is shown in FIGS. 3, 4, and 5, and includes a movable part 17a having a rotary hook 41 at the upper end that is hooked on the tip flange 34 of the pull-out fitting 20, and a strong and dimensionally accurate left and right movable part 17a. horizontal guide rod 17b;
The intermediate drive threaded rod 17c and the drive gear 4
2. It consists of a motor 43 and the like, and the female thread at the bottom of the moving part 17a engages with the threaded rod 17c.

Now, assuming that the rolled-up sheet roll R is moved to the take-out position B as shown in FIG. 1, the carry-out vehicle 2 is advanced to receive and support the upper and lower sheet rolls R by the receivers 2a. Further, the moving portion 17a of the shaft extraction mechanism 17 is advanced, and its hook 41 is automatically or manually hooked onto the collar 34 of the extraction fitting 20 that has rotated together with the winding shaft 13 and stopped. Then, the clamp head 21a of the restraining mechanism 21 is removed by hydraulic pressure. When the extracting motor 43 is now driven, the moving section 17a extracts the winding shaft 13 as shown in FIG. The motor 43 is stopped when the take-up shaft 13 is completely removed from the sheet roll R, and the sheet roll R on the support 2a is moved by the unloading vehicle 2.
to the required location.

The taken-out winding shaft 13 pulls out the tip flanges 34, 34a of the pull-out fitting 20 attached to the tip and moves to the moving part 17a.
Place it on top, and in the middle is the resin receiver 3 of the rotating machine frame 14.
0, 31, and 32 to maintain almost the same axis as the axis during winding. Therefore, when the motor 43 is reversed and the moving part 17a is returned to the position shown in FIG. 3, the winding shaft 13 is smoothly returned to its original position. During this time, a new winding core (not shown) is installed. After the moving part 17a presses the winding shaft 13 against the winding drive mechanism 18 on the rotating machine frame 14' side and engages the tooth clutch 28, it is fixed by the stop mechanism 21 on the machine frame 14 side.
Then, the shaft extraction mechanism 17 is lowered to the standby position and waits for movement to the winding position A.

The rotating machine frame 14, 1 is driven by a drive gear (not shown).
When the large gear 14a of 4' is driven, the main machine frame 1
Both machine frames 14, 14' rotate within a, 1a.
The pulley 27 and gear 26 of the winding drive mechanism 18 are loosely engaged with the rotation center shaft 44 of the rotating machine frame 14', and the force of the driving motor is transferred to the gear 25, which rotates together with the winding shaft 13.
Since the signal is transmitted to the magnetic powder clutch 24, it is possible to rotate the winding shaft 13 regardless of its position.

Although the embodiment shown in FIG. 1 has been described above, the embodiment shown in FIG. This is a winding method in which the arm 60 rises as the sheet roll grows. The sheet roll R drawn by the solid line in FIG. 6 is in a rolled-up state, and when taking it out, the arm 60 is erected vertically and the winding shaft 13 is placed at the take-up position B. The aforementioned shaft extraction mechanism 17 is provided at this extraction position B, and the winding shaft 13 is extracted using the same mechanism and procedure as described above, and the sheet roll R is placed on the receiver 2b. This receiver 2b is configured to receive the sheet roll R with two parallel rolls, and is cantilevered so as to be horizontally rotatable on a vertical column 62 that can be raised and lowered. Once the sheet roll R is placed on the receiver 2b, it is horizontally swung to a position where it will not interfere with the next winding, and then carried out by a crane or the like.

Figure 7 shows a distribution winder similar to Figure 6, but
In this embodiment, the arm 60 swings downward, and the rolled-up sheet roll R is lowered directly below to the take-out position B, and the take-up shaft 13 is pulled out by the shaft pull-out mechanism 17. In this case, the sheet roll R is received and supported in advance by the lift support 2c of the carry-out vehicle 2. Receiver 2
c is raised to receive the left and right sheet rolls R, and lowered to be carried out from below the winder to the side. A small carrying vehicle may be used to take out the sheet rolls R on both sides one by one.

In addition to the above-mentioned example, the distribution winding machine also includes one that sends the sheet from above or below to a common touch roller in the center and winds it on the winding shaft at the end of the left and right hanging swinging arms, and one that winds the sheet on the winding shaft at the end of the left and right hanging swinging arms. Those that wind on the winding shaft at the upper end of the swinging arm, or those that have separate left and right rollers and wind on the left and right winding shafts, etc.
It can vary widely depending on the designer.

FIG. 8 shows an example in which the basic principle of the present invention is applied to sheet roll take-out from a surface drive type winder. 70 is a drum on which the winding shaft 13 and its sheet roll R are mounted and driven to rotate; 71 is a riding roller; 72 is a support arm that supports the winding shaft 13 at both ends and gradually lifts it up; and 73 is an arm 72 that moves up and down.
The guide post 74 is a chain for pulling up the arm 72. The lifting force is between the sheet roll R and the drum 70.
This value is suitable for maintaining an appropriate contact pressure with the

In this case, a drive mechanism for rotationally driving the winding shaft 13 is attached to one side of the arm 72.

Therefore, even in such a drive type winding machine, when the winding shaft 13 rises to a certain position, the present invention can be applied by setting the shaft pulling out position at that position and providing the shaft pulling out return mechanism 17 there. obtain. Without changing the gist of the invention, it can be varied and applied in a variety of ways depending on the design conditions and using the designer's known techniques.

This invention is the first time that a take-up shaft extraction type sheet roll take-out method can be applied to a winder in which the take-up shaft is centrally driven and the position of the take-up shaft is changed. The shaft and the bearing sleeve, which can be pulled out from the winding shaft support part, are made non-separable, and when the bearing sleeve is pulled out using a pull-out fitting provided on the winding shaft, the winding shaft can also be pulled out together with the shaft. The rotational drive is achieved by supporting the end of the winding shaft on the opposite side of the bearing cylinder so that it can be engaged and disengaged, and that rotation is performed by the winding shaft, and when the shaft is in the return state, a pull-out fitting is used. A conventional movable frame for a winding shaft that is restrained by a restraining mechanism, which limits the size of the winding shaft without making the support part complicated or excessive, even for winding shafts that require central drive. The difficult task of pulling out the winding shaft at a desired position, which moves with both ends supported by a movable frame, can be efficiently achieved without hindering the winding operation. I got it.

As a result of the above, the troublesome preparation work of carrying out the winding shaft integrated with the sheet roll to another position, removing it, returning it again and installing it as in the past is eliminated, and the movable machine frame There is no need to provide an extremely complicated mechanism such as a horizontal rotation mechanism for pulling out the winding shaft. In particular, even if a large number of take-up shafts are arranged at various positions on the movable machine frame and are moved one after another to the sheet winding position or sheet roll take-out position, the take-up shaft pull-out and return mechanism is Since only one of the sheet roll take-out positions is sufficient, the apparatus can be simplified. In addition, since the take-up shaft and the pull-out return mechanism can be engaged and disengaged, they can be kept apart except when taking out the sheet roll, and therefore the take-up shaft can be moved by the movable machine frame, for example, in a turning operation. The above-mentioned shaft pull-out and return mechanism does not get in the way during the operation.
