Plug-in device for sandwishing material between layers

Abstract

The invention provides an interlayer material capable of automatically inserting in the interlayer material. This interlayer material insertion device inserts a sheet-typed interlayer material 16 between upper and lower layers of a spacer 12 when the spacer 12 is, in a multi-layer manner, wound around the outer periphery of a rotationally driven bobbin 10 through a traverse mechanism 14. This device is equipped with a winding mechanism 20 which sucks and retains the end of a piece of interlayer material 18 from a stock 18 of the interlayer material 16, presses the interlayer material 16 against a winding spacer and rotates it with the bobbin 10 before the spacer 12 guided by the traverse mechanism 14 runs over the lower winding spacer, and inserts the end of the interlayer material 16 therebetween immediately before the spacer 12 runs over the lower winding spacer, and a winding auxiliary mechanism 26 which controls the turn-up of the interlayer material wound around the winding spacer from the above as bobbin rotates after the winding mechanism 20 releases a condition where the interlayer material is pressed against the winding spacer.

Description

technical field [0001] The present invention relates to an insertion device for inserting an interlayer interlayer when winding a separator for an optical cable. Background technique [0002] Conventionally, the fiber optic cable formed of polyethylene (PE) as the main material is press-molded with a spacer, and then passed through the winding process of the reel formed by the flanges fixed to the cylindrical reel and both ends. , The above-mentioned wound separator is supplied to the optical cable manufacturing process. In the assembly process of optical cable manufacturing, the optical cables are respectively loaded into several grooves of the separator. [0003] In the winding process of the above-mentioned winder, when the separators cross each other, the ribs are prone to deformation, and this deformation will cause abnormalities in the optical cable assembly process or reduce the optical transmission performance of the optical cable as the final product. Separators d...

Problems solved by technology

[0010] With the traditional interlayer inserting method, there will be a gap of more than half the diameter of the winding separator between each final winding layer and the flange of the winder, which makes it difficult to mount on the upper layer , easy to fall and cause bite phenomenon

[0011] The following problems arise here: starting from the 5th round of the final winding, it is necessary to pay attention to the problem of poor winding or embedding. Material insertion, so it takes a lot of time and labor costs

[0012] On the other hand, although the method of winding the ribbon on the support body to prevent the grooves from being engaged has been proposed, it is necessary to increase the bonding and detachment equipment of the ribbon, and the process is increased and the efficiency is reduced, so the cost is also greatly reduced.
