Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a core supply device for automatic winding of sheet material.

[Technical background of the invention and its problems] Japanese Patent Publication No. 47-34065 discloses a method that is equipped with a group of take-up rolls for sheet material, a contact roll, a core supply device, and a cutter device, and has two sets of take-up rolls. An automatic winding device comprising a turret type winding mechanism is described.

However, in this conventional example, the take-up roll group moves in one circular orbit in a counterclockwise direction, and
Above that, a group of pressure rolls is formed to move clockwise on another circular orbit, and one of the take-up rolls and the pressure roll are constantly in contact with each other while moving two circular orbits. Since the pressure roll group disposed above needs to move on an orbit, the center of its circular orbit must slide up and down, resulting in a complicated and large device with a large vertical width. In addition, in addition to having a circular orbit with two stages, upper and lower,
Since the winding core is supplied using the upper circular orbit, the winding core must be transported from a high place to a low place, and replenishing the winding core requires a complicated two-stage acceleration belt and an acceleration belt assembly system. There is also the problem that it requires a mechanism with a large vertical width, resulting in an even larger device. Furthermore, the operating timings of the two-stage upper and lower circular orbits and the two-stage upper and lower accelerator belts can easily deviate from each other, causing the device to stop operating and making continuous high-speed operation difficult, resulting in the problem of large vibrations and shocks.

Furthermore, Japanese Patent Application Laid-Open No. 49-37061 has a 3-station winding device using three sets of winding rollers, a winding core supply section is provided at the lower stage of the main body, and cutter sections are separated from each other at the upper stage of the main body. It is proposed that the

However, in the case where the cutting device and the winding core supply device are arranged on the upper and lower stages of the main body as in this conventional example, the upper winding core, which is a large device with a large vertical width, must also be moved vertically and horizontally, making it difficult to operate smoothly and at high speeds. Driving is difficult. Furthermore, since it is necessary to feed the winding core in the lower stage and cut the sheet under tension in the upper stage, three sets of winding rollers are required, and therefore the sheet cutting position is narrow and high. tend to be in a stable state.

Also, Special Publication No. 36466 and Special Publication No. 40-
Publication No. 11676 describes a device in which continuous winding is performed using two sets of horizontally arranged winding rollers, and one winding roller performs feeding, winding, and winding of the winding core. .

However, since this conventional example does not have a turret revolution mechanism, the mechanism for moving the core between each roller is complicated.The upper core replenishment device and the sheet material winding and cutting device are provided separately and independently. Therefore, there was a problem that it was easy to increase the size.

Therefore, the present invention includes two sets of winding rolls, a rotatable main arm having a presser roll and a cutting blade, and the two sets of winding rolls stop at two horizontal positions during revolution of the turret. In a device in which one winding roll supplies, winds, and takes up the core, and the other winding roll takes out a full roll, the core is supplied in conjunction with the rotation of the main arm. By providing an auxiliary arm for replenishing the reel core integrally with the main arm, the reel replenishment can be carried out in a small space with a small vertical width.The reel replenishment is possible in a compact and smooth high-speed continuous operation for automatic winding of sheet-like materials. The purpose is to provide replenishment equipment.

[Means for solving the problems] The present invention includes a winding core supply section, two sets of winding rolls,
The turret is equipped with a rotatable main arm having a presser roll and a cutting blade, and while the turret revolves, the two sets of take-up rolls stop at two positions in a horizontal position, and one of the take-up rolls is used to supply the winding core, In a device that performs winding and winding and takes out a fully wound roll on the other winding roll side, the winding roll is located between the presser roll and the winding core supply section and is integrally hung from the main arm, Additionally, it is equipped with a pair of auxiliary arms for replenishing the winding core, which can rotate left and right and slide in the axial direction in conjunction with the rotation of the main arm. An auxiliary arm provided integrally with the arm rotates toward the core supply section and slides inward of the shaft to grip one core housed in the supply section, and then unloads the sheet. The tip of the auxiliary arm, which is integral with the main arm, moves between the presser rolls in conjunction with the downward rotation of the main arm to cut the material, and the core is sandwiched between one of the take-up rolls and the presser roll. In this state, the sheet material is cut by the cutting blade and the cut end is wound around the other winding roll, and then the winding core is released by sliding off-axis of the auxiliary arm.

is rotatably mounted on a shaft, and the arm 40 of this shaft rod 39
A second presser roll 41 is rotatably mounted on the tip of the arm 40, and an appropriate power is connected to the shaft rod 39.

The rotation transmitted from the motor to the take-up roll drive shaft 6 is transmitted from the first take-up roll rotation gear 5 to the second take-up roll rotation gear 7 to the parent-child gear 11.
It is transmitted from the parent and child gear 11 to the take-up roll 12 via a pair of third take-up roll rotation gears 14. Therefore, the take-up roll 12 rotates in the same direction.

In this case, since the take-up roll drive shaft 6 is freely rotatable with the take-up roll reversal gear 4, the take-up roll drive shaft 6 moves in a fixed direction regardless of whether the take-up roll reversal gear 4 is stopped or reversed. It is possible to rotate to

In this way, two sets of take-up roll groups a each consisting of a pair of left and right take-up rolls 12 rotating in the same direction at intervals are provided so as to be moved by the revolution of the turret. The take-up roll group a is located horizontally to the take-up roll drive shaft 6, and the machine frame 1
When the sheet-like material I wound up at the center b of the central take-up roll group a reaches a predetermined length, the slide collar 26 slides by a cylinder or the like and the protrusion 2
9 comes off from the winding core 28 and opens the winding core 28. Next, the main arm 21 rotates upward about the pivot rod 22. As the main arm 21 rises, the core replenishing guide 32 rotates around the shaft rod 31 toward the auxiliary arm 27 via the gear 38. Then, the winding core receiving port 33 is located above, and with one winding core 28 fitted into the upper winding core receiving port 33, it is rotated approximately 90 degrees while being held by the stopper rod 34, and the one winding core 28 is assisted. Wait toward the arm 27 side.

Thereafter, the rotation of the take-up roll reversing drive gear 19 causes the take-up roll reversing gears 4 and 4a to start rotating, and the auxiliary arm 27 moves toward the core replenishment guide 32 around the shaft rod 25 while remaining in the open state. Rotate. Next, the protrusion 29 of the auxiliary arm 27
At the same time when both ends of the winding core 28 are reached, the slide collar 26 closes and its protrusions 29 fit into and grip both ends of the winding core 28.

Further, the rotation of the winding roll reversing gears 4, 4a is controlled by a pair of left and right winding roll rotation gears 5, 7, 14 and the first and second winding roll fixing gears 15, as shown in FIGS. 2B and C. , 18, the two take-up roll groups a move half a turn on the same circumference around the take-up roll drive shaft 6 and stop. Since the formed gear 17 is in a fixed state, the first take-up roll fixed gear 15 rotates around this gear 17 while idly rotating on the intermediate shaft 16.

Since the first winding roll fixed gear 15 and the second winding roll fixed gear 18 are in mesh with each other, two lines c connecting the centers of the pair of left and right winding rolls 12,
d rotates around the take-up roll drive shaft 6 while maintaining a parallel state.

In this case, the angle between the two lines c and d maintains a constant angle with respect to the parallel line e of the main body even when the take-up roll reversing gears 4 and 4a are stationary or rotating. In this way, the product end which has been wound up to a predetermined length is placed on the center of the machine frame 1, that is, on the center b of the winding roll group a on the side of the first presser roll 24, while winding up the sheet-like material A. 1, that is, to the second presser roll 41 side.

Also, before the take-up roll reversing gears 4, 4a finish rotating 180 degrees, the auxiliary arm 27 rotates approximately 180 degrees in the opposite direction.
The winding core 28 is rotated once to the bottom surface of the first presser roll 24.
reaches. In this case, the winding core 28 is connected to the stopper rod 34.
is opened against the bullet 35 and removed from the winding core receiving opening 33. Thereafter, the stopper rod 34 is restrained in a vertical state by a restraining member 36.

Next, the main arm 24 becomes almost horizontal, and in conjunction with this, the core replenishment guide 32 rotates, the core receiving port 33 reaches upward, and the core 28 in the core supply section 37 is pushed into the receiving port due to its own weight. 33.

In this way, the winding roll reversing gears 4, 4a
rotates 180 degrees and stops, and the main arm 21
is in a substantially horizontal state, and the core 28 is held between the pair of take-up rolls 12 and the first presser roll 24. At the same time, the arm 40 rotates, and the product opening sent to the second presser roll 41 is connected to the pair of take-up rolls 12.
It is held between the second presser rolls 41 and pressed with a constant force by the second presser rolls 41.

In this case, the sheet-like material I passes through the lower surface of the winding core 28 and is wound onto the product opening. Thereafter, a cutting blade 23 provided at the tip of the main arm 21 is rapidly lowered by an air cylinder or the like to cut the sheet material. At the same time as the cutting, high-pressure air is injected from the nozzle of the air pipe 20, and the cut sheet-like material I is wound around the winding core 28. When the cut sheet material A is wound around the product opening, the second presser roll 41 is raised to become as shown in FIG. 2A. Note that glue or double-sided adhesive tape may be applied to the winding core 28 in advance without using air.

Furthermore, if the balance weight 30 is adjusted to make it lighter, the first presser roll 24 side becomes heavier and the sheet-like material can be rolled up more tightly.

Note that after the main arm 21 becomes almost horizontal as shown in FIG. When the shaped material A is rolled up and becomes larger, the auxiliary arm 27 also rises, and the protrusion 29 at the tip of the auxiliary arm 27 rises, but the protrusion 2
9 is formed smaller than the inner diameter of the winding core 28, the protrusion 29 rises within the inner diameter of the winding core 28 and does not cause any trouble.

Further, the finished product opening may be removed manually after the second presser roll 41 is raised, or it may be automatically dropped by a removal member when the take-up roll group a is subsequently moved. .
