BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overturn prevention device for a coil table which is slit into several lines by a slitter line (slitting device) and bound by a binding machine.

[0002]

2. Description of the Related Art A coil that is slit into several slits by a slitting device or a coil that is banded after being slit has a convex shape on the bottom surface, and when placed on a coil mounting table, the center of gravity of the coil shifts. Easy to fall. Therefore, in this type of conventional apparatus, the coil table is inclined in advance by two to three degrees, and the coil table is inclinedly mounted so that the front end face in the transport direction of the coil is brought into contact with the fixed overturn prevention member provided on the table. I was

[0003]

However, in the case of the inclined mounting method as described above, it is preferable to use a coil made of iron, but in the case of a soft coil made of aluminum or the like, when mounting the coil on a mounting table. The coils rub against each other and may damage the coil end faces, which is not preferable. In order to eliminate such difficulties, a coil mounting table that mounts the coil horizontally has been developed.However, in this horizontal mounting method, there is a problem that the overturn prevention of the rear end face side in the transport direction of the coil is not sufficient. there were.

Accordingly, an object of the present invention is to solve the above-mentioned conventional problems and to provide an apparatus capable of effectively preventing a coil from overturning in a horizontal mounting system.

[0005]

In order to achieve the above-mentioned object, the present invention provides a lifter which mounts a coil and moves up and down to a position above a coil car installed on a bogie in the same direction as the running direction of the coil car. At least one pair of lifters is provided at a predetermined interval at which the lifter can move up and down, and the front end face in the conveying direction of the coil conveyed by the coil car is brought into contact with the fixed type overturn preventing member to place the coil horizontally. This is a coil overturn prevention device provided on the coil holder. The reversing member is provided on at least one side of the coil to be conveyed and opposed to the fixed type overturning member in the coil conveying direction, and is capable of reciprocating in the coil conveying direction. A first actuating member for reciprocating the member, a position contacting the reciprocating member with a rear end face of the coil in the conveying direction, and a position not contacting the reciprocating member. Movable fall prevention member that contacts the rear end surface in the direction to prevent the fall, a second operating member that swings the movable fall prevention member, and a coil that is transported by the coil car has a front end surface that fixes the front end surface. And the second operating member is controlled so that the movable overturn prevention member swings to a position where the movable overturn prevention member abuts on the rear end surface of the coil when the device is mounted on the coil mounting table, and the reciprocating member moves forward. Movable rolling Preventing member is comprises a control device for controlling the first actuating member so as to abut the rear end surface of the coil.

[0006]

Until the coil is conveyed to the coil holder, the movable overturn prevention member is at a position where it does not abut the rear end face in the conveying direction of the coil. When the coil mounted on the lifter and conveyed by the coil car is mounted on the coil mounting table with its front end face in the conveying direction abutting on the fixed type overturn prevention member, the movable overturn prevention member is controlled by the control device. The first operating member swings to a position where it comes into contact with the rear end surface of the coil by the operation of the second operating member, and the reciprocating member also moves forward to the rear end surface side of the coil by the operation of the first operating member. When the movable overturn prevention member comes into contact with the rear end surface of the coil, the coil is brought into a state where one end surface is abutted by the fixed overturn prevention member and the other end surface is abutted by the movable overturn prevention member. Overturning is prevented.

As shown in FIG. 2, a movable overturn preventing member 25 formed in a substantially fan-like shape diverging in the distal direction as shown in FIG.
Are provided so as to be swingable in a direction orthogonal to the reciprocating direction at a position (solid line position) where the coil comes into contact with the rear end surface of the coil 10 and a position (dotted line position) where the coil 10 does not contact the rear end surface. Reference numeral 26 denotes a hydraulic cylinder for swinging the movable overturn preventing member 25, and the rod tip is attached to the end of the hollow tube 15 protruding from the bearing 14 via the crank lever 27. In FIG. 3, reference numeral 28 denotes a band that binds the coils 10 that have been prevented from overturning by the overturn preventing members 12 and 25.

The upper surface of the coil mounting portion 34 is formed so as to be inclined upward from the center in the traveling direction of the carriage 31 toward both sides thereof so that the mounted coil 10 does not fall.
The coil mounting portion 34 is, for example, MC so as not to damage the coil 10.
It is made of nylon. Incidentally, in FIG.
a and the fixed type fall prevention member 12 are omitted.

In the above, a band 28 is used with a binding machine (not shown).
Are mounted on the lifter 32 on the trolley 31 in a state where they are hung and bound. , 25a do not abut against the rear end face of the coil 10,
In FIG. 2, it is at the position of the chain line. When the coil 10 is mounted on the mounting table 8, 8a with the front end face abutting on the fixed type overturn prevention member 12, 12a, the hydraulic cylinders 26, 26a are operated to operate the hollow pipes 15, 15a.

As the screw shafts 16 and 16a are rotated by driving a, the sleeves 23 and 23a are moved forward from a position away from the rear end face of the coil 10 toward the rear end face. When the movable overturn prevention members 25, 25a come into contact with the rear end face of the coil 10, a detection sensor (not shown) detects this, and outputs a signal to the hydraulic motors 18,18.
a, and stop the forward movement. As a result, the coil 10 is brought into contact with one end face of the fixed type fall prevention members 12 and 12a and the other end face of the coil 10 with the movable fall prevention members 25 and 25a. This operation control is automatically performed by controlling the hydraulic cylinders 26 and 26a and the hydraulic motors 18 and 18a by a control device (not shown).

In the above description, the order of the swinging of the movable overturn preventing members 25, 25a by the operation of the hydraulic cylinders 26, 26a and the forward movement of the sleeves 23, 23a by the driving of the hydraulic motors 18, 18a is arbitrary. May be performed first or simultaneously. Also, in the forward movement stop control, the width of the coil 10 is set in the control device in advance, and the motor 18
18a may be driven.

[0014]

Since the present invention has the above-mentioned structure, one end face of the coil is fixed on the horizontal mounting type coil mounting table by the fixed type fall prevention member, and the first operating member is controlled by the control device. (2) The movable fall prevention member on the reciprocating member actuated via the actuating member allows the other end faces of the coil to abut each other to automatically prevent the fall, thereby achieving automation and labor saving of the device. As a result, the effect of preventing the coil from overturning is dramatically improved as compared with the conventional device. Moreover, even a soft coil made of aluminum or the like can be sufficiently mounted on the coil table. Also, instead of a coil car,
Since it is mounted on the coil mounting table provided at a position above the coil mounting table, the coil mounting table serves as a place where the coil is prevented from overturning at any position on the coil transfer path by the coil car,
The coil car can be dedicated to the transfer of the coil, and the transfer efficiency of the coil can be increased. Furthermore, since it is not necessary to provide the coil car itself with the overturn prevention member, the total weight of the coil car can be reduced, and there are excellent effects such as smooth and stable running and simplification of the mechanism.
