Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for conveying a wire rod bundled into a coil cylinder by a winding machine to a cooling process in a wire rolling facility.

In wire rod rolling equipment, the wire rod sent out from the rolling machine is bundled into a coil by a winding machine such as a laying type or a galette type, and the coiled wire rod is transferred to a conveying device and sent to the next cooling process. It is known that this is the case.

The devices shown in FIGS. 1 to 4 have been previously proposed as conveying devices for the coil wire and have been put into practical use, but they still have problems.

In other words, this can be pointed out and clarified as follows.

In the overall configuration shown in FIGS. 1 and 2, 1 is a carrier frame, and on this machine frame 1, a driving device 4 such as a prime mover 2 and a speed reducer 3 is connected to a driving winding body 5 and a conventional winding body. A chain conveying body 7 is hung endlessly between the chains 6 and 6, and the coil wire 9 is transferred and supported on the conveying surface 8 of the conveying body 7, and is conveyed sequentially to the left in the figure.
As shown in FIG. 2, if there is no member to support the coil wire 9 in both outer regions of the chain conveyor 7, so-called sag occurs as shown by symbol A, and the shape stability of the coil wire 9 is poor. , the appearance of the bundle after cooling becomes poor.

Therefore, as shown in FIG. 3, a pair of skids 10 are provided on both outer sides of the chain conveyor 7 to prevent the coil wire 9 from sagging. Rubbing scratches occur on the wire rod 9, and the deterioration of the surface quality due to this becomes noticeable.Nowadays, as the unit weight of coils increases, the occurrence of rubbing scratches is extremely occurring.

Therefore, as shown in FIG. 4, instead of the skid 10, a lifter 12 is provided as a supporting member which is driven (up and down) via a guide part 12A by the expansion and contraction movement of the cylinder device 11. 9
Since the lifter 12 is lowered during conveyance and raised when the conveyance is stopped, it is possible to eliminate scratches on the coil wire 9, but on the other hand, repeated intermittent movements of pushing and releasing the coil wire 9 can For this reason, there are problems in that not only the coil wire 9 lacks shape stability, but also the device is complicated, the operation is complicated, and timing precision is required.

In other words, the above-mentioned conveyance devices and other proposed technologies each have their own merits and demerits.
The current situation is that we are sacrificing one or the other.
In addition, in the conveying device that conveys the coil wire from the winding machine to the cooling process, a transfer machine such as a forklift is used at the beginning and end of the conveyance to transfer the coil wire from the winding machine to the conveying device and from the conveying device to the cooling process. The coil wire must be transported.

That is, the coil wire material from the winding machine is placed on the fork claws of a forklift, and the coil wire material is transferred from the longitudinal direction of the chain transport body at the transport start end onto the transport surface of the chain transport body, and the coil wire material is transferred onto the transport surface of the chain transport body at the transport start end. In the section, the fork claws must be introduced into the carrier body from the longitudinal direction of the carrier body, and the coil wire material on the conveying surface must be transferred to the fork claws.

For this purpose, a loading space into which a fork claw or the like can enter must be secured at the transport start and end of the transport body. This loading space must be large enough to prevent fork claws from hitting the carrier.

However, in the conventional conveying device, skids and lifters to prevent sagging are provided at the start and end of the conveyance, resulting in insufficient loading space, making it difficult to load fork claws, etc. This was difficult, impeded workability, and required skill for charging work.

The present invention has been devised to completely solve the above problems and drawbacks. When the coil wire is transported from the winding machine to the next cooling process,
The object of the present invention is to provide a device which does not cause scratches on the surface of the wire at the bottom of the coil, effectively prevents deformation of the coil wire, and ensures a good package appearance when it is bundled by a bundling machine after cooling. The object of the present invention is to provide a coil wire transport device which improves the transfer operation by ensuring a wide loading space for a transfer machine such as a forklift at the start and end of the transport.

In order to achieve such an objective, in the present invention, a main conveyor and a sub-conveyor are each constituted by a pair of endless conveyors that can freely circulate and are hung parallel to each other.
It is a conveying device in which the conveying surfaces of both conveyors are located on the same plane, the conveying start end is on the winding machine side and the conveying end is on the cooling line side, and two main conveyors 36 are parallel to each other and have the same length. The conveyance length L1 of the two sub-conveyors 44, which are parallel to each other and have the same length, is configured to be short with respect to the conveyance length L of The sub conveyors 4 are arranged so that only the conveyance surfaces 35 of the main conveyors 36 are located at the conveyance end portions 24 respectively.
