Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a winding sheet roll take-out and core mounting device in a sheet division winder in which a plurality of cores are passed through and supported by a common core. Regarding.

(Conventional technology) Conventionally, each time a winding machine winds up a sheet roll,
An operator takes out the sheet roll, including the roll shaft, from the winding machine, lifts it with a crane, and moves it to the roll pulling area, where the roll shaft is pulled 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 present inventor has generally 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 process of transporting the core and fitting the new core onto the core was done by hand.

(Problems to be Solved by the Invention) Recently, sheet rolls supported by the winding shaft of a winding machine have become large in diameter and heavy. The sheet roll tends to shake easily and is unstable when taken out.
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 fitting many winding cores onto one winding shaft one after another, or when winding two winding shafts in parallel. There was a problem of decreased productivity due to interruption of winding.

(Means for Solving the Problems) Therefore, the present invention provides a method in which a plurality of winding cores are passed through and supported by a common winding shaft, and the winding shaft is pulled out from the sheet roll wound on the winding core in that position. After the sheet roll is unloaded, the winding sheet roll unloading and winding core mounting device returns the winding shaft to the unloading position and attaches the winding core to the winding sheet roll. a pedestal capable of receiving a rolled-up sheet roll and movable up and down on the cart; and a gutter-shaped pedestal provided on the pedestal so as to have a length covering almost the entire width of the winding shaft and sandwiching the winding core from above and below. a winding core holder comprising a sandwich plate, an opening/closing arm that supports the upper and lower sandwich plates so as to be openable and closable, and an opening/closing drive mechanism that operates the opening/closing arms symmetrically; , and a fastener that prevents movement of the winding core supported by the sandwich plate in the axial direction.

(Function) Therefore, according to the present invention, once the sheet roll is wound onto the winding core, the cart is moved and the sheet roll holder is raised and lowered to a position where the sheet roll can be received, and the sheet roll is placed at a position where the sheet roll can be received. Remove the roll shaft and transfer the sheet roll to the cradle. Next, the core supported by the upper and lower sandwich plates of the core holding portion provided on the pedestal is placed in the return position of the winding shaft, the winding shaft is returned, and the winding core is attached to the winding shaft. In this case, the winding core is sandwiched between the top and bottom by the gutter-shaped sandwiching plates of the winding core holding section, so it does not move in the radial direction, and is also prevented from moving in the axial direction by the fastener, so it cannot return to its original position. The winding shaft can be passed through the winding core smoothly. When the core has been attached, the upper and lower sandwich plates are opened by the opening/closing drive mechanism, the cart is moved, for example, moved backward, and the sheet roll on the pedestal is carried out.

(Example) The present invention will be described below with reference to illustrated examples.

FIG. 1 shows a first embodiment of the present invention, in which the sheet roll described above is R, a winding shaft that commonly passes through and supports a plurality of winding cores is 1, a pedestal is 2, and a winding core holding part is 3. ,
The trolley is shown as 4, the electric control panel as a control device for the trolley 4 is shown as 5, and the winding core is shown as C. So is the original sheet S,
6 is a slitter (blade) that divides the sheet S into the required width; 7 is a guide roller that distributes the divided sheet up and down; 8 is a swinging arm; the touch roller 9 supported at its tip is initially moved to the winding core on the winding shaft 1; C to prevent air entrainment, and gradually rise as the winding diameter increases.

Figure 1 shows the trolley 4 that was waiting away from the winder.
shows a state in which the sheet roll R has advanced until it hits the stopper 11 at the lower part of the winder frame 10 due to the winding up of the sheet roll R. In this example, a magnetic particle clutch is intervened in the transmission mechanism from the drive motor 12 of the truck 4 to the wheels. The second sheet roll receiving recess 2a is held directly below the center of the sheet roll R.

The pedestal 2 has two stages, upper and lower, each of which is supported by a vertical guide column 13 and an elevating drive screw 14 at positions corresponding to the upper and lower winding positions, and is movable up and down. The upper end of the screw 14 is rotationally driven by a motor 15.

The winding core holding section 3 has opening/closing arms 17 attached to both ends of gutter-shaped sandwiching plates 16, 16 (see Fig. 2) that sandwich the winding core C from above and below, and the upper and lower opening/closing arms 17, 17 are connected to gear parts. They are designed to operate symmetrically, and the lower one is driven by the fluid pressure cylinder 18 to open and close. This fluid pressure cylinder 18 is also controlled by the operation panel 5.

When the carriage 4 is advanced until stopped by the stopper 11, the pedestal 2 is raised, and when the recess 2a reaches the sheet roll R receiving position, the rotation of the screw 14 is stopped by a detection device (not shown) such as a limit switch. Alternatively, the rising of the pedestal 2 is stopped when it hits the lower surface of the sheet roll R, or when it hits and applies some upward pressing force to the sheet roll R. Then, the winding shaft 1 in the winding core is pulled out by the winding shaft insertion/removal device located behind the frame shown in FIG. However, this drawing of the winding shaft 1 is a well-known technique,
As shown in FIG.
As shown in the figure, the bearing 22 at the end of the swinging winding arm 21 is stopped at the unloading position, one end of the winding shaft is clamped by the unloading clamping rollers 23, 23, and the clamping roller is rotated in the pulling direction to receive the winding shaft. It consists of a mechanism for pulling out onto the roller 24, etc., and these are attached to the side of the frame of the winder. 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 in a bearing 22.

As shown in FIG. 4, when the winding shaft 1 is pulled out, the sheet roll R is moved onto the pedestal 2, 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 25 attached to the side of the truck 4 is fully extended as shown in FIG. Separate each roll R by a certain distance to the right from the frame, and move the core C held by the upper and lower sandwich plates of the core holding unit 3 to the sheet roll R.
Make sure that the winding shaft before moving to the right is directly below the position where it was pulled out. Therefore, then pedestal 2
If the core C is raised by a certain distance, the core C will be at the core removal position before the sheet roll moves to the right, and the gripper 19 and roller 23 of the core insertion/removal device will
When the winding shaft 1 is returned to its original position by driving in the direction opposite to the previous direction, the winding shaft 1 enters into the winding core C which is restrained by the winding core holder 3. At this time, the core holding portion must have a restraining action so that the core C does not move due to friction with the winding shaft 1. In other words, in the case of the clamping type from above and below, the pressure that does not deform the winding core C is
Moreover, when the winding shaft 1 enters, the winding core C is compressed to such an extent that it does not move. As shown in FIG. 6, there are fasteners 27 at both ends of the winding core C that do not prevent the winding shaft 1 from entering.
It is also attached. However, in order to arrange the cores C at desired positions intermittently, as in the core holder 3 of FIG. 2, it is preferable to attach a fastener whose fixing position is variable in the axial direction to each core.

When the winding shaft 1 is completely returned to its original position, it is also the time when the mounting of the winding core C on the winding shaft is completed. Therefore, in the embodiment shown in FIG.
7 and 17 in a symmetrical manner to open them, and then open the sandwich plates 16 and 1.
Release the restraint of the winding core by 6, and move it to the pedestal 2 by the trolley 4.
are moved back and away from each winding core C. The motor 12 of the trolley 4 continues to rotate from the time it starts moving forward and even when the trolley is stopped (by slipping the magnetic particle clutch, etc.) to apply forward torque to the wheels and assist in positioning the pedestal 2.
It rotates in reverse only when reversing. However, it is also possible to install sensors at positions corresponding to the sheet roll receiving position and the winding core attachment position, and detecting the above respective positions to stop driving the wheels. The position and the amount of movement to the position corresponding to the core mounting position may be counted by a counter or the like, and the movement of the cart may be stopped when the coefficient reaches a predetermined value.

FIG. 7 shows another embodiment of the cart 4 with two pedestals, which has vertical columns at the front and rear, and has L-shaped pedestals 2, 2 fitted to the front column 13a.
In the embodiment shown in FIG. 1, the operation panel 5 used in this invention, which was coexisting with the operation panel of the winding machine, is now a dedicated operation panel 5' on the carriage 4.

Note that the pedestal 2 may be driven up and down by a pantograph link and a hydraulic cylinder for driving the pantograph link. Further, the winding machine to which the present invention is applied may be of any type as long as it has a winding shaft pulling mechanism. Some of them will be explained below, focusing on the differences from the embodiment shown in FIG. 1 and the like.

First, the one in Fig. 8 has a small swinging touch roller 9 at each of the upper and lower winding positions, and the sheet roll mounting position of the pedestal 2 is not just a recess 2a as in the previous example, but is supported by a spring. The difference is that it is a receiving plate 2b. Furthermore, 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 shown in FIG. 9 is a sheet division winder that winds the winding shaft 1 of the winding arm close to the touch roller 9 in a fixed position.
2 and a hoisting machine 33.

Although a small number of embodiments have been described above, it goes without saying that the present invention is not limited to the embodiments described above, and can be varied and applied in a variety of ways depending on the implementation conditions using well-known techniques of mechanical 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 it away from the touch roller as the sheet becomes thicker. However, it is also possible to support the winding shaft with a sliding support and move it linearly away from the touch roller. Alternatively, the pedestal may be guided and supported on the cart so that it moves forward and backward, and only the pedestal may be moved backward while the cart is stopped when the winding core is attached. Further, as a pedestal, a pedestal having two rotatable parallel bars arranged at an appropriate interval for receiving sheet rolls may be used. The cart may be moved forward and backward by pushing and pulling it manually. 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 rotated in the direction of the workbench. The sheet roll can be conveyed onto the workbench by rolling, with the height adjusted 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. Of course, a so-called turret type winder can be used as the sheet dividing winder.

(Effects of the Invention) This invention attaches a pedestal that moves up and down to a cart that moves forward and backward, and when a sheet division winder with a winding shaft insertion/removal device winds up a sheet roll, the sheet roll is supported by the pedestal and wound. Since the shaft can be pulled out, it is easy to pull out the winding shaft, and the sheet roll can be taken out without being subjected to a falling impact. Furthermore, since the cradle is equipped with a predetermined core holding portion and a fastener that prevents the core from moving in the axial direction, it is possible to hold the new core at the core return position so that it does not move. . Therefore, the operation of returning the winding shaft also completes the installation of the winding core properly. In addition, if the pedestal is stopped just before the bottom surface of the sheet roll, there should be a head difference (gap) 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 supported at one end, the sheet roll is supported by contacting the pedestal due to the deflection of the winding shaft, so this is not a problem. do not have. Of course, in this case, no excessive stress is applied to the winding shaft.

In particular, when winding a large number of sheet rolls at the same time using two winding shafts, or when winding divided sheets by fitting a large number of cores onto a single winding shaft, all the sheet rolls are placed on the cradle at the same time. The productivity improvement effect of being able to take out the top and install all the winding cores at once is enormous.
