Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a core winding machine, and particularly to a core winding machine with automatic switching of multiple bobbins.

[Prior Art] FIG. 3 is a schematic perspective view showing a conventional two-head bobbin type core winder. In the figure, 1 and 2 are shafts, 3 and 4 are one bobbin each attached to shafts 1 and 2, 5 and 6 are fine adjustment screws,
7 and 8 are limit switches.

In a conventional core winding machine, an empty bobbin 3 is attached to one shaft, for example 1, the shaft 1 is rotated to wind a core (not shown) onto the bobbin 3, and when the bobbin 3 is fully wound, the shaft 1 is stop rotating. During this time, the other shaft 2
An empty bobbin 4 is attached to the bobbin 4, and as soon as the shaft 1 stops rotating, the shaft 2 is rotated to start winding the core onto the empty bobbin 4.

Further, the width of the traverser was finely adjusted by turning the fine adjustment screws 5 and 6 many times and moving the positions of the limit switches 7 and 8.

[Problems to be Solved by the Invention] As described above, the conventional core winding machine has the problem that the shaft must be changed every time one bobbin is fully wound with the core.
Further, fine adjustment of the width of the traverser requires turning the fine adjustment screw many times and moving the limit switch, which poses the problem of poor workability.

An object of the present invention is to solve the above-mentioned problems of the prior art, eliminate the need to change the shaft every time one bobbin is fully wound with a core, and improve setup by automatically changing the bobbin. It is an object of the present invention to provide a new core winding machine of a plurality of continuous bobbin automatic switching type, which can reduce the number of times and greatly improve the workability of winding short cores on bobbins.

[Means for Solving the Problems] A multi-bobbin automatic switching type core winding machine according to the present invention includes a plurality of bobbins mounted on one cantilever type shaft by inserting a snacker,
A counter for presetting the full length of the core to be wound on the bobbin, a control panel for automatically switching between a plurality of bobbins one after another based on the full length signal from the counter, and a bobbin. It is equipped with a proximity switch that allows the width of the bobbin to be adjusted with a single touch, and a bearing section that can be set on the free end of the shaft with a single touch. and has a tapered surface protruding from the edge on the empty bobbin side so as to cover the brim of the empty bobbin.

[Function] In the present invention, a plurality of bobbins attached to one shaft are automatically switched one after another by a full length signal from a counter, and
A proximity switch allows you to adjust the bobbin and bobbin widths with a single touch. Furthermore, in the present invention, the above-mentioned snacker allows the core to be transferred from a fully wound bobbin to an empty bobbin extremely smoothly.

[Embodiment] FIG. 1 is a schematic perspective view showing an embodiment of a multi-bobbin automatic switching type core winding machine according to the present invention. In the figure, 11 and 12 are cantilever type shafts made of high-strength SCM material. Since the shafts 11 and 12 are of the cantilever type, their free ends swing or bend considerably during rotation. To prevent this, during operation, one-touch insertable bearings 13, 14 are inserted into the free ends of the shafts 11, 12, respectively, and one-touch-settable bearing receiving arms 15,
16 were installed. Reference numerals 17 and 18 indicate a plurality of bobbins, for example, five bobbins as shown, which are attached to the shafts 11 and 12, respectively. Reference numerals 19 and 20 are guide rolls for the traverse, and counters 21 and 22 with contacts are attached thereto for setting the full length of the core (not shown), respectively. In addition, the bobbin of the traverser and the width of the bobbin are adjusted with a thumbscrew fixed and sliding type that can be adjusted with one touch.
In order to make the switch 3 itself compact, light reflecting type proximity switches 24 and 25 are used.

In the core winding machine configured as described above, first, the length of the core is measured by the measuring device 26, and the counter 21 with contacts, in which the full length of the core has been set, transmits the full length signal to the control panel. 23, the traverse guide roll 19 moves the core from the first bobbin 17-1 to the second bobbin 1 according to a program built into the control panel 23.
Automatically switches to 7-2, counter 21 with contact
gives the full length signal again, and the core is bobbin 17-2.
to the third bobbin 17-3. At this time, in order to ensure that the core is smoothly switched from one bobbin to another, the present invention uses a special snack car shown in FIGS. 2 and 5 A to C instead of the conventional snack car 9 shown in FIGS. shaped snack car 2
7. That is, the tapered surface 27b has eight grooves 27a at predetermined intervals on the edge on the fully wound bobbin side of its outer periphery, and protrudes on the edge on the empty bobbin side so as to cover the brim of the empty bobbin. Snack car 27 with
use. The conventional snack car 9 has a protrusion 9a on its outer periphery, and the core 1 is attached to this protrusion 9a.
This is a method that attracts 0. Therefore, core 10
After being caught by the protrusion 9a, it may become entangled in the collar 30a of the bobbin 30. On the other hand, the snack car 27 used in the present invention has a groove 27a on the edge of its outer periphery on the fully wound bobbin side.
Moreover, a tapered surface 27b is provided on the edge of the empty bobbin so as to cover the brim of the empty bobbin. Therefore, after the core 10 is attracted to the groove 27a on the outer periphery of the snacker 24, it is smoothly wound around the body 30b of the adjacent empty bobbin 30 without getting entangled with the collar 30a of the empty bobbin 30.

In the present invention, in order to shorten the extra switching length when shifting the traverser, the
Made it shift using a separate motor from the traverser feed motor. In addition, the slide speed of the traverser (core feed pitch) is adjusted by adjusting the transmission of the clutch.

Although the present invention has been described with respect to core bobbin removal, it can also be applied to tether and reel removal.

[Effect of the invention] (1) The present invention has the following effects.

Conventionally, the shaft on which a bobbin is attached was changed for each bobbin, but with the present invention, it is only necessary to change the shaft every five or more bobbins, so the number of shaft changes can be reduced to 1/5 of the conventional number. can be reduced.

(2) In connection with the previous item (1), since five bobbins can be changed in succession, the effort required to change the bobbins can be reduced to 1/5 of the conventional method.

(3) The width of the traverse can now be adjusted with a single touch, and by using a light-reflecting proximity switch, the relay in the control panel can be made smaller, and the control panel itself can be made more compact.

(4) By using a snacker that has a groove on the outer periphery of the fully wound bobbin side and a tapered surface that protrudes on the outer periphery of the empty bobbin side so as to cover the brim of the empty bobbin, there is no risk of danger. This makes it easier to switch the core to the next empty bobbin, and the extra length for switching can be shortened.
