Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a spool holder installed in the unwinder section of a paper making machine, and in particular, by improving its structure, it can be operated continuously with the paper making machine. This relates to a spool cradle that can be used.

[Prior art] Generally, paper manufactured from pulp is first processed as an intermediate product by rolling a large diameter winding roll (approximately 3 mφ in diameter, weight
30~40ton). A paper manufacturing machine that adjusts this winding roll to a predetermined width, winding length, etc. and makes it into a product, as shown in FIG. It consists of a slitting device 4 for forming paper 3 to a predetermined width, and a winder section 7 for winding the paper 3 formed to a predetermined width around a core 5a to form a shipping roll 6 having a predetermined winding length. . The above unwinder section 2
is constructed as shown in FIGS. 4 and 5.
As shown in the figure, a large diameter take-up roll 1 is placed on a spool pedestal 8. This spool holder 8
One unit is provided at each end of the spool 5 of the take-up roll 1. This spool holder 8 has a third
As shown in the figure, an arc-shaped recess 9 that engages with the spool 5 of the take-up roll 1 is formed upward.
It is configured to support the spool 5 from below. Further, this spool holder 8 has a structure whose sole purpose is to support and hold the spool 5 of the take-up roll 1, and is of a fixed type.

[Problems to be solved by the invention] By the way, the conventional spool holder 8 has the following problems.

Since the spool pedestal 8 is formed as a fixed type and the arc-shaped recess 9 that engages with the spool 5 of the take-up roll 1 is formed upward, the heavy and large-diameter take-up roll 1 can be easily spooled. There was a problem in that in order to place it on the pedestal 8, it could not be carried out without using a crane or the like (not shown).

Furthermore, the above problems also led to problems that hindered the continuity of operations and the promotion of automation.

Furthermore, since crane work was involved, it was necessary to pay attention to safety.

[Purpose of the invention] The present invention was devised to solve problems in the spool cradle.

The purpose is to provide a spool cradle that can accept heavy take-up rolls in the unwinder section without using a crane or the like, and is durable and safe.

[Structure and operation of the invention] In order to achieve the above object, the present invention has a frame that is installed in the unwinder section of a paper manufacturing machine and has a horizontal introduction stand that rotatably supports both ends of the spool of the take-up roll, and the spool is engaged with the frame. The inertia of the take-up roll is applied when the spool rolls from the horizontal introduction table and engages with the recess. It has a spool holder that is pivotally supported on a pedestal so that it can stand upright, and a locking member that is pivotally supported on the pedestal. The spool holder includes a damping means for absorbing the inertial force of the spool holder, and a lock part provided on the pedestal and biased toward the spool holder. and a locking mechanism that locks the stand in the upright position.

The spool pedestal is turned over to the side of the horizontal introduction table by a resilient member and is on standby, and the take-up roll is rolled and supplied to the spool pedestal from above the horizontal introduction table. Since the spool pedestal is pivotally supported by the frame, when the spool of the take-up roll rolls from the horizontal introduction table and engages with the recess, it automatically stands up due to the inertia of the take-up roll. When the spool is raised, the spool is locked by the locking member of the damping means and the inertial force of the take-up roll is absorbed, so that the impact when the spool pedestal is raised is alleviated. In addition, since the spool pedestal that is upright is locked by a lock mechanism to prevent it from overturning, operational safety is ensured.

[Example] Next, an example of the present invention will be described in detail with reference to the accompanying drawings.

One spool holder is provided at each end of the spool, and is constructed as shown in FIGS. 1 and 2.

As shown in the figure, the spool pedestal 8 is equipped with a large-diameter take-up roll 1 (approximately 3 mφ in diameter and 30 to
An arcuate recess 9 is formed upward to engage with the outer diameter of the spool 5 (40 tons). The end edge 10 of this arc-shaped recess 9 is short on the spool 5 receiving side.
The winder part side is formed long. In order to receive the spool 5 of the take-up roll 1 that has rolled from the horizontal direction, the spool holder 8 tilts toward the receiving side of the spool 5 when the take-up roll 1 is received, and rolls over on its side. Rotating means 11 for standing up in position is provided. As shown in FIG. 2, this rotating means 11 includes a resilient member 12 formed of a coil spring or the like, and a rotating spool holder provided eccentrically on the receiving side of the spool 5 of the spool holder 8 main body. It consists of a fulcrum shaft 13. The resilient member 12 connects a lug 15 provided on the side edge of the spool holder 8 on the spool 5 receiving side and a pedestal 16 of the spool holder 8. The spool pedestal 8 receives a tensile force from the elastic member 12, and is always in an overturned state when no load is applied by receiving the take-up roll 1. Also, the first
As shown in the figure, a rail 30 and a horizontal introduction stand 17 are provided on the spool 5 receiving side of the spool holder 8 for auxiliary introduction of the spool 5 into the spool holder 8 when receiving the spool 5 from the horizontal direction. ing. The spool holder 8 also has a structure for mitigating the impact applied to the spool holder 8 due to the inertial force of the take-up roll 1 when the spool holder 8 stands up by receiving the take-up roll 1. A damping means 14 is arranged in parallel. This damping means 14 consists of a locking member 18 formed in a substantially triangular shape and a shock absorber 19. The end of the locking member 18 on the spool 5 receiving side is engaged with a locking member rotation fulcrum shaft 20 provided at the upper edge of the pedestal 16 on the winder side. A reinforcing structure 21 is formed on the side edge of the locking member 18 on the spool 5 receiving side to receive the impact caused by the inertial force of the take-up roll 1. This locking member 18 rotates about the locking member rotation fulcrum shaft 20, and when the spool pedestal 8 is overturned,
Alternatively, when erected, the reinforcing structure portion 21 is positioned along the edge of the arc-shaped recess 9 of the spool holder 8 on the winder portion side. Particularly, when the spool pedestal 8 is overturned, the reinforcing structure 21 and the edge of the arc-shaped recess 9 of the spool pedestal 8 on the winder side are located substantially flush with each other. Since the outer diameter of the spool 5 at the portion in contact with the arc-shaped recess 9 is formed to be thin in order to prevent the spool 5 from shifting laterally, the reinforcing structure 21 is attached to the spool 5 when receiving the take-up roll 1. It is designed to touch first. Further, the above-mentioned shock absorber 19 is connected to the end of the above-mentioned locking member 18 on the winder section side. The base end 22 of this shock absorber 19
is fixed, and expands and contracts when the locking member 18 rotates about the locking member rotation fulcrum shaft 20.

Furthermore, as shown in FIG.
A lock mechanism 23 is provided to prevent the spool holder 8 from overturning again due to the reaction caused by the inertia of the take-up roll 1 after the spool has been received. This lock mechanism 23 includes a lock portion 25 biased by a coil spring 24, supports this lock portion 25 on its base end, and extends curvedly from this base end toward the spool 5 receiving side. Arm member 2
6, a lock mechanism rotation fulcrum shaft 27 for rotating the lock portion 25 and arm member 26 facing each other, a base end portion of the arm member 26 on which the lock portion 25 is supported, and a spool holder 8. and a lock part engaging member 29 provided on the side edge of the spool holder 8 on the winder part side to engage with the lock part 25. This lock mechanism 23 is configured such that before the take-up roll 1 is received, that is, when the spool holder 8 is overturned, the base end of the arm member 26 on which the lock portion 25 is supported is secured by a coil spring or the like. The tensile force of the formed elastic member 28 causes the frame 16 to
descending to the side. The arm member 26 that rotates opposite to the lock portion 25 is raised and protrudes above the arc-shaped recess 9 of the spool holder 8, so that the spool 5 is rotated in a circular manner when receiving the take-up roll 1. It is configured to come into contact with the arm member 26 earlier than the arcuate recess 9. Then, in synchronization with the reception of the spool 5 of the take-up roll 1, the arm member 26 is pushed down by the spool 5, whereby the lock portion 25 is raised to a predetermined position and the spool holder 8 is raised up. By doing so, the lock portion engaging member 29 engages with the lock portion 25 from above. This lock portion engaging member 29 is tapered, and this taper allows the lock portion 2
By compressing the coil spring 24 of No. 5, the lock portion engaging member 29 enters inside the lock portion 25 and is restrained.

Next, the operation of the spool holder 8 constructed as described above will be described.

The present invention is configured to receive a take-up roll 1 rolling from a horizontal direction. The take-up roll 1 rolling from the horizontal direction is placed on the rail 3 provided on the receiving side of the spool 5 of the spool holder 8.
0 and on the horizontal introduction table 17, thereby being auxiliary introduced into the spool holder 8. At this time, that is, before the take-up roll 1 is received, the spool pedestal 8 is subjected to a tensile force by the resilient member 12 of the rotation means 11, and the spool pedestal 8 is rotated around the spool pedestal rotation fulcrum shaft 13. It rotates and is tilted toward the spool 5 receiving side and rolled over. Similarly, the spool cradle 8
As the spool holder 8 of the locking member 18 of the damping means 14 arranged in parallel with
It rotates around 0 and is rolled over. At this time, the reinforcing structure part 21 of the locking member 18 is positioned substantially flush with the winder part side edge of the arc-shaped recess 9 of the overturned spool holder 8. This locking member 18
The rollover is achieved by the shock absorber 19 of the damping means 14 being expanded by an internal coil spring. Furthermore, when the spool pedestal 8 is in a state of being overturned, the arm member 2 of the locking mechanism 23 is
6, the base end including the lock portion 25 is the resilient member 2.
The spool holder 8 receives a tensile force from the spool holder 8 and descends, thereby rising, and protrudes above the arcuate recess 9 of the overturned spool holder 8. Next, when receiving the take-up roll 1, the spool 5 first comes into contact with the arm member 26 of the lock mechanism 23 that protrudes upward from the arc-shaped recess 9 of the overturned spool holder 8, and while pushing it down, the damping means After contacting the reinforcing structure 21 of the locking member 18 of 14, the spool holder 8 contacts the arc-shaped recess 9 of the overturned spool holder 8, and the spool holder 8 pivots around the spool holder rotation fulcrum shaft 13 of the rotating means 11. It rotates as a center and stands up in a predetermined position.
In synchronization with the rising of this spool pedestal 8, the locking member 18 of the damping means 14 rotates about the locking member rotation fulcrum shaft 20 and stands up, thereby causing the damping means 14 to rise. A load is applied to the absorber 19 due to the inertial force of the take-up roll 1.
That is, when the spool pedestal 8 stands up, an impact due to the inertial force of the take-up roll 1 is applied to the spool pedestal 8, but this impact is alleviated by the damping means 14. Furthermore, a reaction occurs in the spool holder 8 due to the inertia of the take-up roll 1, and the spool holder 8 tries to roll over again, but the lock mechanism 23 prevents the spool holder 8 from rolling over again.
will be restrained while standing up. In this mechanism, when the take-up roll 1 is received, the arm member 26 of the lock mechanism 23 is pushed down and rotates about the lock mechanism rotation fulcrum shaft 27, and the lock part 25 that rotates opposite to this is rotated. It is raised and placed into position. A lock part engaging member 29 provided on the side edge of the winder part side of the spool pedestal 8 engages with the lock part 25 located at a predetermined position from above as the spool pedestal 8 stands up. . Then, the taper of the lock portion engaging member 29 compresses the coil spring 24 of the lock portion 25.
The lock portion engaging member 29 enters inside the lock portion 25 and is restrained. Further, since the edge 10 of the arcuate recess 9 formed in the spool pedestal 8, located on the winder section side, is formed in a long protruding manner, the take-up roll 1 is rolled into the winder section. It doesn't roll off to the side.

As described above, since the take-up roll 1 can be received from the horizontal direction and no crane or the like (not shown) is used, an integrated operation that is continuous with the paper machine is achieved, promoting automation. It turns out.

[Effects of the invention] In summary, the present invention provides the following excellent effects.

(1) A take-up roll is supplied by rolling from a horizontal introduction table to a spool holder that is lying on its side, and when the spool of the take-up roll engages with the recess in the spool holder, the take-up roll Since the spool pedestal automatically stands up due to the inertial force of becomes possible.

(2) When the spool pedestal stands up, the spool is locked by the locking member of the damping means to absorb the inertia of the take-up roll, which reduces the impact when the spool pedestal stands up. This improves its durability and prevents noise.
