Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-core wire feeder such as a cable assembly or twisting machine, and particularly to a bobbin mounting device for a multi-stage feeder.

When manufacturing electrical cables, especially communication cables, a method is adopted in which unit twisting and rope twisting are performed in one process, so it is necessary to supply a large number of core wires, and the number of bobbins on which the core wires are wound increases, resulting in a multi-stage delivery system. equipment is used.

A conventional delivery device has a configuration as shown in FIGS. 1 and 2.

That is, the core wire 2 wound around the bobbin 1 is sent out to the twisting machine via the guide 3.

In this type of delivery device, a bearing 5 is provided on the pedestal 4,
A sliding and rotatable cone-equipped shaft 6 is attached to this, and by moving the shaft 6 with a sliding device 7, the bobbin 1 is held and understood.

The above numbered portions 3 to 7 are referred to as a sending section A (see FIG. 2).

Further, the conveyance of the bobbins is performed by a conveyor 9 having a power source 8 disposed below the row of bobbins 1 held between the shafts 6 with cones.

The above numbered parts 8 and 9 are referred to as conveyance section B (see FIG. 2).

) In this way, the conveying section A and the conveying section B are set as one set, and the base legs 10 and 11 are interposed to form a multi-stage structure.

The bobbin is transferred to each stage by a bobbin lifting device 12.

Such conventional devices have a number of drawbacks, including:

(1) Each stage is provided with a conveyor, but since the lifting device is shared by each stage, there is no time-based transport between each stage.

In other words, it cannot be used at each stage.

(2) Since a conveyor is provided in each stage, the machine height H1° becomes high, and the machine becomes large, especially in the case of multiple stages.

(3) Since the bobbin holding method is a double-held type using a shaft with a cone, the bobbin is located in the center of the machine, and the east line can be drawn out.
Difficult to set up connections etc.

(4) If there is an accident such as a defect in the installed bobbin, it is difficult to partially replace it.

(5) The structure is complicated, large, and expensive.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a novel multifilamentary wire delivery device that overcomes the drawbacks of the conventional techniques described above, has a simple and compact structure, and is capable of increasing work efficiency.

According to the present invention, an alignment stand for arranging bobbins at regular intervals, a taffeta for raising and lowering the bobbins, and a mount having bobbin holding shafts arranged at equal intervals to the bobbin intervals are provided, and the bobbin holding shafts are arranged at regular intervals. The above object can be achieved by using a cantilevered structure in which the bobbin can be attached and detached by moving them forward and backward.

Next, a multifilamentary wire delivery device according to the present invention will be described with reference to illustrated embodiments.

As shown in FIGS. 3 and 4, a feeding device according to an embodiment of the present invention employs a multi-stage feeding device that supplies a core wire 2 wound around a bobbin to a twisting machine (not shown) via a wire guide 3. will be held.

The delivery device according to the present invention includes an alignment table 13 for aligning bobbins at predetermined intervals, a lid 14 for raising and lowering the alignment table, and a pedestal 16 having bobbin mounting shafts 15 arranged at equal intervals to the bobbin intervals. equip

The bobbin mounting shaft 15 is integral with the shaft 21, and is configured so that its outer diameter can be expanded and contracted, so that the bobbin 1 can be fixed.

The shaft 21 is rotatably attached to the slide shaft 17, and the slide shaft 17 is fitted into the bearing stand 16.

Further, the slide shaft 17 is connected to a power source capable of advancing and retracting, for example, a hydraulic cylinder 19, via a connecting fitting 18, so that the bobbin mounting shaft 15 can be taken in and out.

It is preferable that a bobbin positioning fitting 20 is provided on the bobbin alignment table 13 so that the bobbin 1 can be aligned by matching the spacing between the bobbin mounting axes.

The bobbin alignment table 13 can be raised and lowered by a lifter 14, and the height can be adjusted when installing and removing bobbins at each stage.

Next, we will discuss the bobbin mounting method and operation.

First, fully wound bobbins placed on a predetermined floor are placed on a bobbin alignment table set at the same level.

Although the device for putting in is not shown, it depends on the person or the conveyor.

When a predetermined number of fully wound bobbins are lined up on the alignment table 13, the first condition for lifting the lid 14 is satisfied.

It is preferable that the bobbin is attached in the order starting from the top row and then moving to the bottom row.

At first, the bobbin mounting shafts 15 of all stages are retracted, and it is confirmed that all the bobbin mounting shafts are retracted, and the second condition is set such that the lifter 14 is raised.

It is convenient to use a detector such as a limit switch or sensor to measure these first and second conditions.

When the above two conditions are met, the lifter 14 is raised.

When the full bobbin on the sorting stand reaches the top position, remove the lid 1.
Stop 4.

Next, the uppermost bobbin mounting shaft 15 is projected and inserted into the hole of the bobbin 1 to mount the bobbin.

It is preferable that a large number of bobbin mounting shafts can be put in and taken out at the same time, and that the bobbin mounting shafts can also be mounted all at once.

Once the top row has been installed, lower the lid and return the alignment table to the floor.

Next, a fully wound bobbin is loaded, adjusted for 1 time, raised to the next stage, and the bobbin is installed in the same manner.

In the case of disassembling the bobbin, it is preferable to perform the operation in the opposite direction to that for installing the bobbin, starting from the lower stage and moving sequentially to the upper stage.

It is convenient if the sorting table is configured with a cart or a conveyor and has a conveying function.

In addition, although the starting and stopping of the operation may be done manually, it is also possible to make it automatic by providing various detection devices and command devices.

The delivery device according to the invention offers many advantages over conventional ones, such as:

(1) The bobbin alignment table system with a lifter allows the conveyor that was conventionally provided at each stage to be omitted, and the machine height can be significantly reduced.

(2) The bobbin is held in a cantilevered manner, allowing the width of the machine to be reduced.

Although only one side is illustrated in the embodiment, it is particularly effective when provided on both sides.

(3) Since the bobbin is held in a cantilevered manner, there are no obstacles between the work surface and the bobbin, and the workability of drawing out the core wire, monitoring connections, etc. is greatly improved.

(4) Part of the bobbin can now be replaced, which was previously impossible.

(5) The structure is simple, compact, and inexpensive.
