Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic winder device applied to various machines for winding web-like products such as those used in paper machines, and more particularly, it is equipped with an automatic double-sided adhesive tape application device to apply tape to a winding core. can be attached and the material to be wound can be automatically wound.

As paper machines become faster and wider, winder devices are required to save labor and automate their operations. However, in the conventional two-drum winder, (a) the paper cores to be held between the front and rear drums are fed by manually dropping them one by one between the two drums. The work of wrapping the paper passed under the rear drum and then between both drums around the paper core requires manual work to glue the paper and paper core together using duct tape, etc. This was to start winding.

Under these circumstances, the necessity of manually supplying the core and winding the paper around the paper core once every 5 to 10 minutes has made it impossible to realize one-man control of the winder.

In addition, conventional means for applying adhesive to the winding core by spraying have been available, but this has been problematic because the drum surface has been contaminated with the adhesive.

The present invention was made in order to eliminate the above-mentioned drawbacks.
The core is set in the standby position and double-sided adhesive tape is applied using an automatic pasting device.The core is then transferred over the front drum, set in position again, and then clamped.Then, the clamped core is placed on the front drum. To provide a winder device with an automatic pasting device that can supply a web-like product to a fixed position between a drum and a rear drum and automatically wind a web-like product around a core at the start of winding.

To enable continuous descent, retreat, and rise, so-called rectangular movements.

In FIGS. 1 and 2, 38 is a double-sided adhesive tape 39 to be wound up, and 40 is a rider roll. Next, the effect will be explained.

First, the deceleration position detection knob 22A and the fixed position detection knob 2
A winding core 3 provided with a winding core 2B is housed in a core standby box 5 and supported by a support member 6, as shown in FIG.

By a worker or by a limit switch (not shown),
By detecting that the winding core 3 is in the standby position and synchronizing the chuck cylinders 17 and 21 into an extended state, the winding core 3 is moved to the chuck cylinder 2.
Chucking is performed by the piston rod 1 and the output shaft of the reducer 18. Thereafter, a signal is sent from the pulse motor operation panel 24 to the drive unit 25, and the pulse motor 19 rotates normally in response to the pulse signal from the drive unit 25, and this rotation causes the winding core 3 on standby to rotate at a low speed. When the winding core 3 rotates, the deceleration position detection knob 22A first comes into contact with the proximity switch 23A, and the electric command from the limit switch 23A is switched to a command to decelerate the pulse motor 19 on the pulse motor operation panel 24, and the drive The pulse motor 19 is rotated at a reduced speed by the pulse signal from the unit 25, and therefore the winding core 3 is also rotated at a reduced speed. Subsequently, when the winding core 3 rotates by a small angle and the stop position detection knob 22B comes into contact with the proximity switch 23B, an electrical command from the proximity switch 23B is sent to the pulse motor operation panel 24, and the pulse The motor operation panel 24 is switched to a command to stop the pulse motor 19, and the pulse motor 19 is stopped by the pulse signal from the drive unit 25. In this way, the winding core 3 is stopped at a fixed position. After that, the cylinder 27 will extend, and the rail 26 will rise until the striker 29 comes into contact with the limit switch 28A and then stop, and the geared motor 34 will rotate forward to move the roller chain 3.
2, the double-sided adhesive tape pasting body 31 as shown in FIG.
However, while this double-sided adhesive tape 38 is in contact with the lower surface of the winding core 3, the striker 37A switches the limit switch 36.
The double-sided adhesive tape 3 is towed along the axial direction under the winding core 3 until it comes into contact with A.
8 is applied and the double-sided adhesive tape 38 is automatically cut at the running end. Subsequently, the cylinder 27 is compressed, the rail 26 is lowered, and the striker 29 is activated by the limit switch 28.
When the rail 26 stops descending upon contact with the rail 26, the geared motor 34 rotates in reverse to tow the double-sided adhesive tape application body 31 via the roller chain 32 until the striker 37B contacts the limit switch 36B. In this way, the double-sided adhesive tape automatic pasting device T completes the one-time tape pasting operation. Subsequently, when the chuck cylinders 17 and 21) of the first positioning device R are retracted to release the chuck, the cylinder 9 of the transfer device is extended to lift the rail 7.

For this purpose, the winding core 3 in the standby position is lifted up with both ends supported by the rail 7, and when the swinging end of the rail 7 becomes higher than the base end and the cylinder 9 completes its extension operation, it rolls on the rail 7 to the stopper. It is stopped by the arm 11 on the rail 7 above the front drum 2. Thereafter, the winding core 3 is chucked and rotated by the second positioning device S in exactly the same manner as the operation of the first positioning device R described above, and the winding core 3 is placed in a fixed position and chucked. Next, when the cylinder 14 of the clamping device is operated, the positioned winding core 3 is clamped again, and the cylinder 15 of the drop-in device is contracted, and the stopper arm 11 is moved freely as shown by the imaginary line in FIG. It is rotated to a certain position and then stopped. Therefore, the winding core 3 is positioned at a fixed position by the clamping device and dropped between the rear drum 1 and the front drum 2, and is held down by the rider roll 40, after which the clamping device clamps the winding core 3. It will be canceled. Next, rear drum 1
The material to be wound 39 is rotated and guided between the rear drum 1 and the front drum 2 through the underside of the rear drum 1.
Automatic winding is performed by adhering to the outer surface of the double-sided adhesive tape 38 attached to the winding core 3 at the nip between the winding core 3 and the rear drum 1.

Thereafter, the transfer device and dropping device return to their original positions. The present invention is not limited to the illustrated and described embodiments; for example, a knob may be attached to the winding core to instruct the pulse motor to decelerate and stop; A limit switch or the like automatically detects that the core is on standby and causes both chucking cylinders to perform synchronous extension operations, and both chucking cylinders are connected to the completion of one cycle of pasting operation of the double-sided adhesive tape automatic pasting device. The transfer device is made to perform a synchronous contraction operation so that the transfer device can be operated continuously in response to the reduction operation, and the transfer device, the second positioning device, the clamp device, and the dropping device are automatically linked in sequence. The movable arm of the clamp device may be rotated to close the inlet portion, etc., and other changes may be made without departing from the gist of the present invention. Of course.

As described above, the winder device with an automatic pasting device of the present invention detects the position of the winding core at the standby position, affixes the double-sided adhesive tape, and transports the winding core to a position above the front drum. After that, it detects the fixed position again, clamps it, and places it between the rear drum and the front drum, so the double-sided adhesive tape attached to this winding core is In addition to solving the difficult technical problem of ensuring that the material does not stick to either the rear drum or the front drum, the material to be wound can be automatically wound onto the winding core, and the winder can be completely It has excellent effects such as automation and labor saving.
