Abstract

PURPOSE:To make this sheet roll takeout device applicable to a winder being different in winding and takeout positions, by making a bearing cylinder undetachable from a shaft of the wound sheet takeout device, while pulling out a winding shaft from outside the bearing cylinder by means of a drawing device. CONSTITUTION:When wound sheet rolls R are transferred to a takeout position, a carrying-out car is moved forward and these upper and lower sheet rolls R are supported by a receiving device 2a. Likewide, a tranfer part 17a of a shaft drawing mechanism 17 is moved forward whereby its hook 41 is turned round together with a winding shaft 13 and hooked to a collar 34 of a drawing device 20 being stopped thereat. After that, a clamp head 21a of a check mechanism 21 is detached off by means of fluid pressure. With this method, when a drawing motor 43 is driven, the transfer part 17a pulls out the winding shaft 13. When this shaft comes off completely, the motor 43 is stopped, thus these sheet rolls R are carried out. The drawn winding shaft 13 places its tip collars 34 and 34a of the drawing device 20 attached to the tip end on the transfer part 17a. The point midway in transfer is supported by each of plastic receiving cylinders 30, 31 and 32 belonging to a swivel machine frame 14, therefore the same axis as an axis in time of winding is kept up. Accordingly, the winding shaft 13 returns to the original position in a smooth manner.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding sheet roll take-out device for a winding machine.

Conventionally, in order to efficiently take out the sheet roll wound around the take-up shaft by a take-up machine, it is necessary to either take it out of the machine by attaching it to the take-up shaft to reduce downtime, or move one end of the take-up shaft to the side for 15 minutes. ~
A method has been used in which the sheet roll is pulled out of the machine by turning it by 25 degrees (Japanese Patent Laid-Open No. 141345/1983). There is also a core holding method that does not use a winding shaft, but this cannot be used when multiple sheet rolls are to be wound around a single winding shaft.

Two years ago, the inventor of the present invention developed a device for supporting a sheet roll from below with a carry-out holder at the position where the sheet roll has been wound up, and then pulling out the winding shaft, which was disclosed in Japanese Patent Application Laid-Open No. 57-141642. Since this method involves winding up at a fixed position and unloading at that position, it cannot be applied to winders of different types with different winding and unloading positions.

The present invention solves the above-mentioned difficulties and opens the door to applying a sheet roll take-out device of the take-up shaft removal type to winders of different types with different take-up and take-out positions.

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 and a sheet roll delivery vehicle 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//, distributed into upper and lower sections, and then passed through a touch roller//, respectively.
2 and then wound onto the winding shaft /3. The winding shaft /3 is supported between a pair of well-known rotating machine frames (turret plates) /2/Hiro', and from the winding position A in contact with the touch roller l-,
In this example, it can be moved to the take-out position B on the opposite side. Figure 1 shows the newly wound sheet roll R being moved to the take-out position B.
This figure shows the state before the winding shaft 13, which has been waiting with a new winding core installed at the take-out position B, is moved to the winding position A and a new winding operation is started. If the winding and unloading positions are separate in this way, it is possible to take out the sheet roll R during winding or to install a new core.

The winding shaft support parts /1, /, f of the rotating machine frame /≠' and the shaft extracting mechanism 17 are shown in FIGS. 2-4. First, an outline of the configuration of the present invention will be described with reference to this embodiment.It consists of opposing support parts/6. /,! In the winding machine l which supports the winding shaft /3 at both ends by r, one of the above-mentioned supporting parts /! The bearing cylinder 3, which irremovably supports one end of the winding shaft 3, is removably fitted into the bearing cylinder. 13 end is attached with a pull-out fitting SO that elastically presses the end directly, and at the take-up shaft extraction position, in this case, take-out position B, hold the pull-out fitting 20 in its mouth and remove both the bearing cylinder and the take-up shaft/3. It is equipped with a shaft pull-out return mechanism /7 that leaves the unloaded and wound-up sheet roll R on the unloading holder σ, and also controls the escape of the winding shaft /3 through the pull-out fitting; tO, except when the shaft is pulled out. This is a hoisting sheet roll take-out device characterized in that a restraining mechanism is attached to the machine frame.

The rotating machine frames /≠, /l' are commonly called turret disks, and are supported and driven so as to face each other and rotate integrally by the main machine frame /α of the winding machine /. Since it is well known, the explanation will be omitted, but FIG. 2.5 shows a cross section of only the vicinity of the winding shaft support portions is and i6 of the rotating machine frames /II' and /g. A large diameter gear/4tα for turning drive is attached to the outer peripheral side.

In this case, the support part /j 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. The supporting part /J is the bearing that penetrates the rotating machine frame//7' horizontally and is fixed to it. The drive shaft 23 is rotationally driven by a large drive motor (not shown) through gears 5 and 7, and gears 6 and pulleys 17, which are loosely coupled to the rotation center shaft 4t4t of the machine frame/≠'. . .

The tip of the drive shaft 23 (left end in Figure 2) is a cylindrical tooth clutch 2g and a conical portion 2 for supporting the winding shaft protruding from the center thereof. is attached. When the winding shaft /3 is pressed, the conical portion 2? is crowded, the winding shaft, the two-scratches on both end faces of the drive shaft, and 2g engage.

The support part /6 in FIG. 5 supports the winding shaft /3 so that it can be pulled out. For this reason, the shaft end of the winding shaft /3 is made a little X-thin, and a bearing cylinder whose outer diameter is the same as that of the winding shaft /3 is fitted therein. That bushing/? It has a unique configuration in which the take-up shaft/3 is pulled out from the top.

Therefore, this bushing/j? The resin receivers 30, 3/ on the swivel frame/4L side that support the winding shaft/3 have the same inner diameter as the receivers 32 for the winding shaft/3, and all of them will support the winding shaft/3 when the shaft is pulled out. .

In addition to the function of bearing the winding shaft /3, the bearing cylinder /9 also has the function of holding the shaft when it is taken out or returned. The height of the seats of the four balls or roller bearings 33 makes it impossible to separate the shaft/3 and the bearing sleeve/3.

The tip of the extraction fitting 20 is inserted into the outer end side where the bearing 33 is not provided.

The extraction fitting 20 is caught by the collar 3g on which the hook of the shaft extraction mechanism/7 is hung, the collar 3j on which the flang head of the restraining mechanism 2/ is hung, and the restraining tube 37 attached to the inner wall of the bearing sleeve, making it impossible to escape. In order to do this, there is a tsuba (3) screwed into the tip of the metal fitting (3). In addition, a coil spring 3♂ and a pressure rod 3F are inserted into the center of the front end surface of the extraction fitting 20, so that the bearing cylinder/7 and the winding shaft/3 are elastically pressurized via the plate Hiroshi 0. There is.

After the winding shaft 13 is pulled out and the two rolled-up sheet rolls R are placed on the carrying-out holder 2cL and carried out as shown in FIG. 5, the winding shaft/3 is immediately returned to its original position. At the time of extraction, the clamp head 2/a5 of the restraining mechanism, which had been retracted to the chain line position, moves to the solid line position in Figure 5 when the winding shaft 3 returns.
The winding shaft 3 is pressed and fixed to the drive mechanism through the pull-out fitting 20, and the tooth clutch J is connected. The above-mentioned restraining mechanism 2/ is a commercially available product, and is advantageous because it is of a type in which the clamp head 27α is not moved straight by fluid pressure, but is pushed forward a little and then held down.

The shaft pull-out return mechanism /7 is shown in Fig. 6.4.5, and is a rotary hook≠/7 that is hooked on the tip hook 3≠ of the above-mentioned pull-out fitting 20.
The moving part /7α has a movable part at the upper end, the left and right horizontal guide rods /7b, which are strong and have good dimensional accuracy, and the drive threaded rod /7c in the middle.
1. It consists of drive gears t, L2, motor tag 3, etc., and the female screw at the bottom of the moving part /7a engages with the threaded rod /7c.

Now, suppose that the rolled-up sheet roll R is moved to the take-out position B as shown in Fig. 1.
The upper and lower sheet rolls R are supported by the receiver. Also, advance the moving part/7α of the shaft extraction mechanism/7, and the hook≠l
The flange 3 of the pull-out fitting 20 has rotated and stopped together with the winding shaft/3.

Pull out the winding shaft/3 as shown in the figure. When the winding shaft /3 is completely removed from the sheet roll R, the motor ≠3 is stopped, and the sheet roll R on the receiver 2cL is transported to a required position by the transport vehicle.

The taken-out winding shaft 13 is placed on the pull-out metal fitting attached to the tip, the tip hook 3≠, 3'l (L) is pulled out and placed on the moving part/7cL, and the resin receiver of the rotating machine frame/≠ is inserted in the middle. 30, 3/
, 3.2 to maintain the same axis as the axis during winding. Therefore, when the motor tag 3 is reversed and the moving part /7α is returned to the position shown in FIG. 5, the winding shaft /3 is smoothly returned to its original position. In the meantime, install a new winding core (circuit). Push the winding shaft /3 to the winding drive mechanism / on the rotating machine frame /≠' side using the moving part /7 (L), and when the tooth clutch r is engaged, the stop mechanism Yu l on the machine frame /≠ side Then, the shaft extraction mechanism/7 is lowered to the standby position and waits for movement to the winding position A.

When the large gear l≠a' of the rotating machine frame /II-, /≠' is driven by a drive gear (not shown), both machine frames /≠, /≠' rotate within the main machine frame /α, /. . Winding drive mechanism/Which pleats 7, gears, 26 play around the rotation center shaft 11.4t of the rotating machine frame/4t' to transfer the force of the driving motor to the winding shaft/3
Gear 23. Since the information is transmitted to the magnetic particle clutch, it is possible to rotate the winding shaft /3 regardless of its position.

The above description has been made based on the embodiment shown in FIG. 1, but in 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. When taking it out, the arm 60 is stood vertically and the take-up shaft 13 is moved to the take-up position BVC.

In this case, the support is supported in advance by the lifting support C of the transport vehicle tB. Raise the receiver CF and release the left and right sheet rolls R.
It is then lowered and carried out from under the winder to the side. A small carrying vehicle may be used to take out all the sheet rolls R on both sides one by one.

In addition to the above-mentioned example, the type of winding machine used for sorting is one that feeds 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. Various designs may be used depending on the designer, such as winding on a winding shaft at the upper end of a vertical swinging arm, or winding on left and right winding shafts with separate touch rollers.

The guide column 7t of the arm 7.2 is a chain for pulling up the arm 72. The value of the pulling blade is suitable for maintaining the contact pressure between the sheet roll R and the drum 70 appropriately. A drive mechanism for rotationally driving the winding shaft 73 may be attached to one of the seven arms as an auxiliary device.

The present invention can also be applied to this surface drive type winder by setting the winding shaft /3 at a certain position as the shaft pull-out position and providing the shaft pull-out return mechanism 77 there.

In this case, generally the take-up shaft support shown in FIG. 2 simply becomes a shaft support that can be inserted and removed.

The above embodiments are examples showing the advantage that the present invention can be applied even when the winding position and take-out position are different, and it can also be applied to other similar types. It is not a moat that it can be used even when both positions are the same. The summary of the invention can be varied and applied in various ways according to the design requirements and by the well-known techniques of the designer without changing the substance of the invention. We were able to adopt a shaft extraction type sheet roll extraction method. The shaft and the bushing that can be pulled out from the winding shaft support are made non-separable, and when the bushing is pulled out using a pull-out fitting inserted into the inside from the outer end of the winding shaft, the winding shaft is pulled out along with it. What I did,
When the shaft returns (d), the pull-out fitting directly elastically presses the end of the winding shaft, and the pull-out fitting is stopped by a restraining mechanism, which allows the winding shaft to move with both ends pivoted. They were able to efficiently accomplish the difficult task of pulling out the material at the required location without any trouble in terms of time, money, and winding.
