Consequently, the sheet roll R is received onto said table 2 without falling thus to mechanically fit the core C simultaneously with resetting of the winding shaft 1.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a winding sheet roll take-out and core mounting device in a sheet winding device.

<Conventional technology> Conventionally, each time a sheet roll was wound up by a winding machine, an operator would take out the sheet roll along with the winding shaft from the winding machine, lift it with a crane, and move it to the winding shaft extraction location, where the winding shaft would be removed. Pull it out. Then, when attaching that or another core to the winding machine, a new cylindrical core was inserted onto the core, and the sheet was wound onto it. The inventor has previously developed a winding machine that extracts the winding shaft from a rolled-up sheet roll on the spot and returns the winding shaft after the sheet roll is carried out. In this case, too, the sheet roll is received by a crane. The work of transporting the core and fitting the new core onto the core was done by hand.

<Problems to be solved by the invention> As the sheet rolls supported by the winding shaft of the winding machine have recently become large in diameter and heavy, it is necessary to lift them with a crane and take them out of the winding machine. The problem is that the sheet roll easily shakes and has poor stability. Further, in the case of a winder that winds the sheet up and down, both sheet rolls cannot be taken out at the same time.

On the other hand, the work of fitting the winding core onto the winding shaft after transporting the sheet roll is labor-intensive and time-consuming, such as when a large number of winding cores are fitted one after another onto a single winding shaft, or when winding two winding shafts in parallel. There was a problem of decreased productivity due to overcasting and interruption of winding.

<Means for Solving the Problems> The present invention provides a method for extracting the winding shaft from a rolled up sheet roll in that position, and returning the winding shaft to the multi-extracting position after the sheet roll is carried out. In the winding core mounting device, a pedestal for receiving the rolled-up sheet roll, a winding core holder, a cart carrying the pedestal and its elevating drive mechanism and moving back and forth, and operating the elevating drive mechanism of the cradle. and an operation panel for extracting the winding shaft.
It is characterized by being able to control movement of the winding core.

Note that the trolley is not limited to one that moves on wheels, and may be a movable platform with similar functions.

<Operation> This invention does not use the conventional method of changing the direction of the wound sheet roll or taking it out and then pulling out the roll shaft.
11 of this paper is directed to a winding machine developed by the present inventor that has equipment for extracting the winding shaft on the spot, and the sheet roll wound up by this winding machine is taken out. During winding, it waits on the side of the sheet roll, but when the winding is completed, when it moves forward, the movement of the trolley is regulated by a guide mechanism, rail, etc. so that the sheet roll holder will be directly under the target sheet roll. are doing. Of course, as the cart moves forward, when the pedestal is placed directly under the sheet roll, the lifting drive mechanism raises the pedestal to a receiving position where it touches the bottom surface of the sheet roll or just in front of it. If anything, it will be easier to pull out the roll shaft by lightly pushing up the sheet roll, raising the pedestal to a point where it will share the weight, and then pulling out the roll shaft.

Once the sheet roll is placed on the pedestal, the conventional approach is to immediately move the truck to the bottom of the crane and transport the sheet roll out with the crane.

However, in the present invention, before that, the core held by the core holding portion of the pedestal is moved to the multiple winding shaft extraction position by moving the pedestal. Then, by the operation of returning the extracted winding shaft to the multiple extraction position, it is inserted into the aforementioned winding core that is waiting there. A core holding part that can control the movement of the winding core when inserted is attached to the pedestal, and the trolley is equipped with a drive mechanism to raise and lower the cradle as appropriate, and the trolley can of course move forward and backward. As a result, as described above, the sheet roll can be received from the winding shaft without falling onto the pedestal, and the winding core can be mechanically fitted into the winding shaft at the same time as the winding shaft returns. In addition, when the pedestal is stopped just before the lower surface of the sheet roll, a head difference (gap) may occur between the two within a range that does not affect the sheet roll. However, even if there is some gap between the two, when the winding shaft is in a one-end supported state, the sheet roll is supported by contacting the pedestal due to the deflection of the winding shaft. Of course, in this case, no excessive stress is applied to the winding shaft.

Also, if the winding core does not fit into the winding shaft, lower the holding part or
Needless to say, it is released and the truck is moved backward together with the sheet roll.

<Embodiment> FIG. 1 shows an example in which the present invention is applied to a split winder (slitter winder). The aforementioned sheet roll is shown as R1 with the winding shaft as 7, the pedestal as 2, the core holding part as 3, the trolley as 1, and the electric control panel as the control device as 51 and the winding core as C. SQ is the original fabric of sheet S, O is a slitter (blade) that divides the sheet S into the required width, 7 is a guide roller that distributes the divided sheets vertically,
g is a swinging arm, which initially presses the touch roller love against the winding shaft/upper winding core C to prevent air entrainment, and gradually rises as the diameter of the winding changes.

FIG. 1 shows a state in which the cart, which has been waiting away from the winding machine, has advanced until it hits the stopper at the bottom of the winding machine frame 10 due to the winding of the sheet roll R. In this example, a magnetic particle clutch is intervened in the transmission mechanism from the drive motor 2 of the bogie to the wheels, so that the bogie can move forward (//
Do not stop the drive of the motor 2 even after it hits the roller, and keep the sheet roll receiving recess α of the cradle on the carriage directly below the center of the sheet roll R. There is.

The pedestal has two levels, upper and lower, and is supported by a vertical guide column 3 and an elevating drive screw 3 at positions corresponding to the upper and lower winding positions, and is elevated and lowered. The upper end of the screw /lI is driven many times by the motor /S.

In this example, the winding core holder 3 has opening/closing arms/closing arms at both ends of gutter-shaped clamping plates tb, tb (see Fig. 2) that sandwich the winding core C from above and below.
Add 7, upper and lower opening/closing arms/? , /? The gear parts mesh with each other so that they operate symmetrically, and the lower part is driven by a fluid pressure cylinder/g. In theory, this fluid pressure cylinder 7g is also controlled by the operation panel S.

Advance the trolley until it is stopped by the stopper /l, raise the pedestal, and when the recess α reaches the receiving position of the sheet roll R, a limit switch or other various detection devices (not shown) stop the rotation of the screw /l. stop. Alternatively, the rising of the pedestal 2 is stopped when it hits the lower surface of the sheet roll R, or when an upward pressing force is applied to the sheet roll R to some extent due to the collision.

Then, the winding shaft / in the winding core is pulled out by the winding shaft insertion/removal device behind the frame IO shown in Fig. 1. This is a well-known technique, and the non-driving end of the winding shaft / is pulled out as shown in Fig. 4. Grip it with the gripping tool /9 and pull it out along the rail 1O, or pull out the two bearings at the end of the swinging winding arm as shown in Fig. 5, and park it in the position. Holding roller for extracting one end of 23
．． ．． It consists of a mechanism that clamps the material by pressing it against the socket 23, rotates the clamping roller in the pulling direction, and pulls it out above the socket 22.
It is attached to the side of the winder frame. Note that the drive gear and the like at the other end of the winding shaft are removed before being pulled out, and the other end of the pulled out winding shaft is supported within the bearing.

As shown in FIG. 4, when the winding shaft is pulled out, the sheet roll R is moved onto the cradle, and then a winding core mounting process unique to this invention begins. That is, in the embodiment shown in FIG. 1, the rod of the positioning fluid pressure cylinder SS attached to the side surface of the cart t is stretched out as shown in FIG. Separate the sheet roll R by a certain distance to the right from the frame IO, and remove the core C in the core holding part 3.
so that it is directly below the position where the roll shaft was pulled out before the sheet roll R moved to the right. Therefore, if the pedestal C is then raised by a certain distance, the winding core C will be at the winding shaft extraction position before the sheet roll moves to the right. When the roller 23 is driven in the opposite direction to return the winding shaft/, the winding core C enters into the winding core C which is restrained by the winding core holder 3. At this time, the winding shaft/
The core holding portion 3 must have a restraining action so that the core C is moved by friction. In other words, if the core holder 3 is of the clamping type as shown in Figures 1 to 5, the core C can be clamped with a pressing force that does not deform the core C, but that is sufficient to prevent it from moving when the core C is advanced. However, the core holding section 3 is not limited to the clamping type. For example, as shown in Figure 6.7, the U
It may be simply fitted into a mold receiving groove roller and provided with fastener cores at both ends that do not prevent the winding shaft from entering. However, in this type, it is necessary to attach fasteners to each side of the winding core in order to arrange the winding core C at required positions at intervals, as in the core holding section 3 in Fig. 2. It is preferable to allow the fixing position of the fastener to be freely changed in the axial direction.

When the winding shaft l is completely returned to its original position, it is also the time when the winding core C has been attached to the winding shaft, so in the embodiment shown in FIG.
, and in the receiving groove type core holding section 3 shown in Fig. 6.7, lower the pedestals a little to separate them from the respective cores C, and move the cart backward.

Motor 2 of the trolley continues to rotate from the time it starts moving forward, even when the trolley is stopped (by slipping the magnetic particle clutch) to provide forward torque to the wheels to assist in positioning the pedestal, and rotates in reverse only when moving backward. .

Fig. 8.9 shows another embodiment of the cart with a pedestal.

The one in Figure 8 has vertical columns at the front and rear, and the front column has /3
α is fitted with an L-shaped pedestal Yu and Yu, and in the embodiment shown in Fig. 1, the operation panel S of this invention coexists with the operation panel of the winding machine.
is pushing the trolley to the special operation panel S' above.

The embodiment shown in Fig. 9 is the core holding part 3 shown in Fig. 6.7, that is, simply attaching the core C receiving groove roller and the fastener depth to the cradle λ. The lifting and lowering drive is also performed by a simple pantograph type link and a fluid pressure cylinder 2q.

The winder to which this invention is applied may be of any type as long as it has a winding shaft pull-out mechanism. Embodiments in which the present invention is applied to various types of winding machines will be briefly described with reference to FIG. 10 and subsequent figures.

In Figure 10, the divided sheet is divided vertically by the touch roller 9 rotating at a fixed position, and the upper and lower winding arms g, the winding shaft at the tip of g are brought close to the touch roller 9, and the sheet is rolled as shown by the chain line. After winding up the sheet roll R, each roll is moved to the roll shaft removal position shown by the solid line, the winding shaft is pulled out, and the sheet roll R is placed on the cart cradle that has advanced as described above. The winding core holding part 3 on the curved edge of the stand 2 is of a horizontal clamping type. The lifting and lowering mechanism of the pedestal is illustrated in a simplified manner.

The one in Fig. 11 has a small swinging touch roller 9 at each of the upper and lower winding positions, and the sheet roll mounting position on the pedestal is a mere recess α as in the previous example and is supported by a spring. The difference is that it is a receiving plate λb. Further, when the receiving plate 2b rises and comes into contact with the sheet roll R and the displacement of the spring reaches a predetermined amount, a detection switch (not shown) is activated to automatically stop the rising.

The one in Fig. 12 is a winding machine in which the sheet roll 9 swings, and the winding shaft l is rotated at a fixed position and is inserted and removed. At the tip of 30, a clamp-type winding core holder 3 that opens and closes using a fluid pressure cylinder/g is attached.

After raising the winding core C in the winding core holding part 3 to the height C' of the winding shaft extraction multiple position (in this case, the winding multiple position) by the pivot gear 3/ of the arm 30, the trolley By moving the roller back a certain distance, the winding core C can be placed at the extraction position 1b.

In the case of Fig. 15, the winding arm g is moved to the touch roller 9 in the fixed position.
This is a winding machine that winds the winding shaft by bringing the winding shaft closer together, and the mechanism for raising and lowering the pedestal of the cart is three wire lobes and a winding machine 33.

The winding machine shown in Fig. 14 has a winding shaft / at both ends of a turret-type rotating arm 3'l, and after winding up the sheet roll R using the touch roller 9 on one side, it is rotated 180 degrees to the opposite side and taken out. This is a well-known format. In this case, the cart lifts and lowers the pedestal using hydraulic pressure, and the sheet roll placement position on the pedestal is set to two parallel S pipes with an extra dimension of 35.

The winding machine shown in Fig. 15 is also of the winding shaft turret type, but in this case, a disk-shaped swing machine frame 36 is used instead of the swing arm, and these are arranged vertically to support the winding shaft. The sheets are divided and wound up alternately. The device for inserting and removing the winding shaft l is shown in FIG. 4. The winding core holder 3 uses the receiving groove type described above, but in this case, it is not supported by a cradle, but by a support on both sides that is pivoted at one point on the machine frame 36 fixed to the trolley. It is supported by the tip of the arm 37. The arm 37 is driven to swing up and down by a drive mechanism (not shown), so that the core holder 3 is passed over at least the cradle in the direction in which the cradle enters the winding machine. At the position C', which is the same height as the position of the winding shaft for both sheet rolls R, and when the pedestal enters the winding machine, it collides with the sheet roll supported by the winding shaft. It can be stopped at position C, which is at a height that does not occur. Therefore, when the winding shaft / is pulled out and the sheet roll R is transferred to the cradle, the winding core holder 3 is moved to the position C' by swinging the arms 3, and the carriage 1 is moved back a certain distance. Core C can be removed and placed in multiple positions. After the winding core C is attached to the winding shaft l, the arm 37 is swung to the position C'' to remove the winding core C from the winding core holder 3.

It goes without saying that the present invention is not limited to the above-mentioned embodiments, but can be varied and applied in various ways according to implementation conditions using well-known techniques of machine designers.

For example, the winding machine of the embodiments described so far either winds the winding shaft with the winding shaft in a fixed position, or supports the winding shaft with a swinging arm and swings the sheet winding shaft away from the sheet roll. However, the winding shaft may be supported by a sliding support and moved linearly away from the touch roller. Alternatively, the pedestal may be guided and supported on the truck so that it moves backward in both directions, and the pedestal may be moved backward when the truck is stopped when the winding core is attached. The cart can be moved forward and backward by pushing and pulling it manually, or by pushing and pulling it manually.
The raising and lowering of the pedestal may also be done manually or by providing an operating handle on the raising and lowering drive mechanism. Furthermore, if the pedestal can be horizontally rotated on the cart, when the cart with the sheet roll placed on the pedestal retreats to the vicinity of the workbench for the next process, the tip of the pedestal can be turned toward the workbench. , the sheet roll can be conveyed onto the workbench by adjusting the height to the top surface of the workbench. The operation panel can be freely designed, from one that commands each operation individually to one that automates all operations.

<Effects of the Invention> In this invention, a platform that moves forward and backward is equipped with a pedestal that moves up and down, and when a winding device with a winding shaft insertion/removal device winds up a sheet roll,
Since the roll shaft is pulled out while supporting the sheet roll with the above-mentioned pedestal, the roll shaft can be pulled out easily and the sheet roll can be taken out without falling impact, but the cradle also supports the roll core. The new winding core can be attached to the winding shaft extraction position using the operation panel and held while moving, so that the winding core installation is completed by the operation of returning the winding shaft.

Especially when winding a sheet roll with two winding shafts at the same time,
When a large number of cores are fitted onto a single roll shaft and the divided sheets are wound up individually, the present invention allows all the sheet rolls to be taken out onto the cradle at once and all the cores to be installed at once. The productivity improvement effect is enormous.

In particular, with winding machines that wind up large-diameter sheet rolls, the winding position exerts a high force, making it difficult to work when unloading the sheet roll and increasing the danger. Although it was necessary to take measures such as storing the winding machine and adjusting the winding shaft position to a position suitable for the unloading position, it can be said that the problem of the winding shaft height limitation has been alleviated by this invention.
