Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a gluing dryer.

"Prior Art" In a pasting drying device, a cylinder drying portion is connected to a drive motor, and a deceleration brake device is attached to the cylinder drying portion or utilizes braking force of the drive motor. This is because the moment of inertia of the cylinder dry part is larger than that of other parts. Then, the normal rotation torque and the stop braking force were transmitted from the cylinder drying portion to the glued portion by the driving motor.

Since the length of the dryer is large in the gluing dryer that has a dryer such as hot air between the gluing portion and the cylinder drying portion, the transmission device between the cylinder drying portion and the gluing portion is generally several. A transmission shaft and a coupling must be used, and a gear device for adjusting the peripheral speed is provided between the roller and the cylinder. Therefore, the glued part as seen from the cylinder dry part has a play with all the play (clearance) of these joints and the gear device added. Moreover, these plays are promoted by the wear of the parts associated with the use of the device. Therefore,
In a glued dryer in which the cylinder drying part is connected to the drive motor or reduction brake, the joint or gear of the transmission device is used when the drive motor is generating drive torque and when the reduction braking force is working. The play directions of the device are all in the opposite direction.

The disadvantages of this are as follows: 1) When shifting from the operating state to the decelerating state, the play of each individual component of the transmission device is reversed, and at that time, each component of the device is impacted and the life of the component is significantly shortened. Therefore, especially when the recent speeding up of the gluing dryer is suddenly stopped, the transmission torque required for deceleration is greater than the transmission torque required for gluing during acceleration or steady operation, and it is caused by reversal of play. Since a shock is applied, a stronger transmission device is required.

2) At the time of restart, the play direction during deceleration due to the braking force,
Since the play at the time of the subsequent restart is reversed, at the time of restart, the start of the glued part is delayed with respect to the start of the cylinder drying part. This causes the yarns and the like on the sizing machine to be stretched, which adversely affects the yarns and deteriorates the workability during inching operation.

3) In many cases, the thread sheet of the sizing machine (in which a large number of threads are arranged) is supplied from the beam, and at that time, the beam sheet and the thread sheet between the sizing machine have a brake device attached to the beam.
By controlling the torque, the tension is kept constant. In this case, in order to reduce tension fluctuation due to beam inertia at acceleration or low speed, the drive motor is started, accelerated,
When it begins to slow down, it gives a signal to the beam drive. However, as described above, when the direction of the play of the transmission device is reversed, the drive of the glued portion is delayed much more than the drive motor, and the delay changes depending on the amount of the play. Therefore, there is a gap between the start-up, acceleration, and deceleration synchronization timing signals transmitted from the drive motor control device to the beam drive device and the actual movement of the glued portion from the beam into which the thread sheet and the like enter, and the beam and glue It becomes difficult to keep the tension of the thread sheet and the like between the attachment machines constant.

In addition, even if a timer is used to adjust the time temporarily, it will not synchronize as the amount of play changes.

[Problems to be Solved by the Invention] The present invention provides a transmission device having a small capacity, except for the above-mentioned drawbacks 1), 2), and 3) by attaching a brake device to a glued portion in a glued drying device. The purpose is to always drive the cylinder dry part and the glued part without any play between them.

"Means for solving the problem" In a device having a glued portion and a cylinder dried portion, the glued portion and the cylinder dried portion are connected by a connecting shaft, and the cylinder dried portion is connected to a driving motor. , A gluing drying device characterized in that a braking device is attached to this gluing portion.

"Operation" By attaching a brake device to the glued portion and operating this brake device at the time of deceleration, the direction of play of the joint of the transmission device and the gear can always be one side.

That is, if the driving torque is transmitted from the cylinder dry portion to the glued portion and the brake torque is transmitted from the glued portion to the cylinder dried portion, the play of the transmission device is always in one direction.

"Embodiment" Fig. 1 shows the whole of this invention, (A) is a gluing machine,
(B) shows a dryer [this is a pre-dryer for hot air drying, high frequency drying, etc.], and (C) shows a cylinder dryer.

These (A), (B), and (C) devices are arranged in the order of processes, and the thread (Y) wound around the beam (1) is indicated by the arrow.
It will proceed in the direction of (a). (2) is a feed roller, and the yarn (Y) is introduced into the sizing machine (A) for sizing, and then dried while passing through the dryer (B). It is sufficiently dried by passing through each cylinder of the cylinder dryer (C), guided in the direction of the arrow (a ') and wound up in the beam (1'). (M ₁ ), (M ₂ )
Is a drive device (motor) for each beam.

The feed roller (2) is provided with a brake device (3), and an electromagnetic valve (4) for operating the brake device (3), a pressure regulator (5), and a compressed air source (6) are attached.

On the other hand, each cylinder of the cylinder dryer (C) is driven by a prime mover motor (M ₀ ), and this driving energy goes through a bevel gear (7), a gear device (G ₁ ) provided on the connecting shaft (S), and a joint. _{[coupling] (c 1) ~ (c} 4), bevel gear (7 '), the joint (c _5), the gear unit (G _2), the joint (c _6), reportedly bevel gear (7'), the aforementioned It goes through the braking device (3) to the feed roller (2).

(P) is a control device for controlling the drive motor (M ₀ ) and the solenoid valve (4). In the figure, (8) is the sizing roller of the gluing machine, and (9) is the roller chain of the cylinder dryer.

Incidentally, in the conventional device of this type, the brake device is arranged in the portion shown by the phantom line above the bevel gear (7) on the cylinder dryer side.

Even if a brake device is attached to the cylinder drying part in order to stop the device as soon as possible, if the following relationship is established for the braking ability of the brake device corresponding to each part, the glued part will be the cylinder drying part. In this case, the brake torque is transmitted from the glued portion to the cylinder portion because the brake torque is to be stopped first.

Js, Bs: Moment of inertia and brake torque of the glued part converted to the transmission shaft axis Jc, Bc: Moment of inertia and brake torque of the cylinder dry part converted to the transmission shaft axis Generally, the drive motor (M ₀ ) Its speed is controlled according to the indicated curve, and this pattern is
As shown in the figure, start (D ₁ ), acceleration (D ₂ ), operation (D ₃ ), deceleration (D ₄ ), stop (D ₅ ). In this case, the prime mover (M ₀ )
The cylinder drying section connected to is controlled according to this pattern. Therefore, if the braking device (3) for the glued portion produces a braking force that tries to stop the glued portion faster than the deceleration curve shown in FIG. 2 [state of (D ′ ₄ )] during deceleration. , The play of the transmission device is unidirectional. That is, the brake torque of the glued part should satisfy the following equation, ω: angular velocity of the transmission shaft t: time When the deceleration rate is constant as shown in Fig. 2, Eq. (2) is Since ω / T is a constant value, Bs should be larger than a certain value regardless of the operating speed.

[Advantages of the Invention] In the present invention, a gluing dryer is equipped with a braking device at the gluing portion on the upstream side of the entire process, so that a transmission device such as a joint or a gear for acceleration, operation and deceleration, and stop is The play side is always in one direction, and there is no impact applied to these mechanisms especially during deceleration, resulting in long-term durability.

Further, the drive delay of the cylinder dry portion and the glued portion to the beam due to play is eliminated, and the controllability is improved.

It is useful not only for the device thread of the present invention but also for paper-like ones.
