[Problems to be solved by the device]

 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 such as aluminum, when the coil is placed on the mounting table, the coils rub against each other and the end faces of the coil are scraped. It could be damaged and was not preferred. Therefore, in order to eliminate such difficulties, a coil holder was developed to horizontally mount the coil.However, in this horizontal mounting method, the fall prevention on the rear end surface side of the coil in the transport direction is not sufficient. was there.

Therefore, an object of the present invention is to provide a device which solves the above-mentioned conventional problems and can effectively prevent the coil from falling over in a horizontal mounting system.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a reciprocating member which is provided on at least one side of a coil to be transported in the above-described coil mounting table and which is capable of reciprocating along the coil transport direction. The first actuating member for reciprocating the moving member, and the reciprocating member are provided so as to be swingable in a direction intersecting the reciprocating direction between a position in contact with the rear end face of the coil in the conveying direction and a position in which the coil does not contact the rear end face in the conveying direction. The movable fall prevention member that comes into contact with the rear end face in the conveyance direction to prevent falls, and the second operation member that swings the movable fall prevention member.

The movable fall prevention member is in a position where it does not contact the rear end surface of the coil in the transport direction until the coil is transported to the mounting table. When the coil is placed on the stand with its front end face in the transport direction abutting against the fixed fall prevention member, the movable fall prevention member swings to the position where it abuts the rear end face of the coil by the second actuating member. At the same time, the reciprocating member is also moved forward to the rear end face side of the coil by the first operating member. When the movable fall prevention member comes into contact with the rear end surface of the coil, one end surface of the coil is brought into contact with the fixed fall prevention member and the other end surface is brought into contact with the movable fall prevention member. , Fall is prevented.

A coil mounting part 11 made of metal is attached. In this embodiment, the coil 10 is composed of several strips having the same width as shown in FIG. Reference numeral 12 is a fixed type fall prevention member that abuts the front end surface of the coil 10 and is arranged in parallel with the machine base 1.

A reciprocating member 13 is installed on the side of the machine base 1 opposite to the coil mounting table 8 along the carrying direction of the coil 10 and at a position outside the outer diameter of the coil 10A having the maximum width. . As shown in detail in FIG. 3, the reciprocating member 13 includes a hollow tube 15 rotatably supported by a pair of bearings 14 and a screw shaft concentrically rotatably arranged in the hollow tube 15. 16, a screw shaft 16 and a hydraulic motor 18 for rotating the screw shaft 16, which is attached to the end of the hollow pipe 15 protruding from the one end opening of the screw shaft 16 via a coupling 17. It has a nut 19 and consists of a connecting portion 21 protruding outward from a long groove 20 formed in the axial direction of the hollow tube 15 and a sleeve 23 fixed by a bolt 22 and fitted into the hollow tube 15. The sleeve 23 reciprocates in the direction of the arrow by driving the motor 18. S indicates a moving stroke of the sleeve 23.

As shown in FIG. 2, the sleeve 23 does not come into contact with a position (solid line position) at which the movable fall-prevention member 25 formed in a substantially fan-like shape diverging toward the tip end comes into contact with the rear end face of the coil 10. It is provided so as to be swingable in a direction orthogonal to the reciprocating direction at a position (chain line position). Reference numeral 26 is a hydraulic cylinder for swinging the movable fall prevention member 25, and the rod tip end portion is attached to the end portion of the hollow tube 15 protruding from the bearing 14 via the crank lever 27. In FIG. 3, 28 is a band formed by binding the coils 10 that have been prevented from falling by the fall preventing members 12 and 25.

In FIG. 2, reference numeral 30 is a hydraulic motor for moving a bogie 31 of the coil car 3, 32 is a lifter for moving the coil 10 provided on the bogie 31 up and down, 33 is a hydraulic cylinder for moving the lifter 32 up and down, and the lifter 32 is mounted. In order to prevent the placed coil 10 from falling, the upper surface of the coil placing portion 34 is formed to be inclined upward from the center of the traveling direction of the carriage 31 toward both sides thereof. The coil mounting portion 34 is made of, for example, MC nylon so as not to damage the coil 10. In FIG. 2, the reciprocating member 13a and the fixed fall prevention member 12 are omitted.

In the above, a plurality of coils 10 are placed on the lifter 32 on the carriage 31 in a state in which the band 28 is hung and bound by a binding machine (not shown), and the plurality of coils 10 conveyed by the traveling of the carriage 31 are transferred to the stands 8, 8a.
