Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an automatic bobbin attaching / detaching device capable of attaching and detaching a bobbin or a drum which is generally used for winding.

[Prior Art] In the process of manufacturing electric wires, etc., the bobbin wound with the electric wires is mounted at a predetermined place, and after the work is completed, the bobbin is removed and transferred to the next process automatically without human intervention. Need to do.

5 and 6 are perspective views of a conventional bobbin attaching / detaching device having different configurations.

In FIG. 5, the air cylinders 3 are used to press the pressing plates 2 against both side surfaces of the bobbin 1 to clamp the bobbin 1. In FIG. 6, the bobbin 1 is slidably mounted. The bobbin 1 is mounted so as to be pressed down from above and below by the two pressing plates 5.

[Problems to be Solved by the Invention] Among the above-mentioned conventional techniques, in the example shown in FIG. 5, a large force is required for press-contacting the side surface of the bobbin. And, because of the risk of falling, it cannot be applied to heavy objects.

Further, in the example shown in FIG. 6, there is a risk that the bobbin will fall off from the left and right side surfaces.

Further, in the above example, it is necessary to use an air cylinder or an oil cylinder for both of them, and it is not possible to make the apparatus compact.

An object of the present invention is to provide an automatic bobbin attachment / detachment device that solves the problems of the prior art, simplifies the component structure, and improves reliability and safety.

[Means for Solving the Problem] The present invention provides an arc-shaped rocking member supported by a fixed support member so as to be rockable in the circumferential direction via rollers.
A drive device for swinging the swinging member and a semicircular container mounted on the circumferential surface of the swinging member for attaching and detaching the bobbin are provided.

[Operation] In the present invention, the semicircular container is attached to the arcuate rocking member, and when the bobbin is attached and detached, the rocking member is moved in the circumferential direction to make the container upside down. Was restored to the original state.

Therefore, when the bobbin is contained in the container, the risk of falling is extremely small, and the safety is improved.

Further, since the bobbin can be attached and detached by the swinging mechanism and the meshing mechanism of the chain and the sprocket is used for the driving device thereof, the component structure is simplified.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show an automatic bobbin attaching / detaching device according to this embodiment, and FIGS. 1 (a) and 2 (a) are front views of the same.
FIG. 2B and FIG. 2B are side views thereof.

1 (a), (b) and 2 (a) (b), 6 is a semi-circular container for attaching and detaching the bobbin 1, 7 is an arcuate swing member, 8 is a roller, and 9 is A support member fixed to a predetermined wall surface or the like, 10 is a chain provided on the outer periphery of the swing member 7,
Reference numeral 1 denotes a sprocket that meshes with the chain 10. The container 6 is mounted on the circumferential surface of the rocking member 7, and the container 6 is fixed to the rocking member 7 when the rocking member 7 is moved in the circumferential direction. I have to. The swinging member 7 is supported by a supporting member 9 via a roller 8 so as to be swingable in the circumferential direction. In addition, the side surface of the container 6 has a shape in which the center portion of the arc is slightly cut out in order to facilitate the delivery of the bobbin 1.

The operation of the bobbin automatic attachment / detachment device will be described below.

When the bobbin 1 is attached to or detached from the container 6, the meshing mechanism of the chain 10 and the sprocket 11 is driven to move the swing member 7 to the first position.
Move it in the direction of arrow A in the figure to move the container 6 as shown in FIG.
To the inverted position.

When the bobbin 1 is housed in the container 6 or removed from the container 6, the swinging member 7 is moved in the direction of arrow B in FIG.

According to the present embodiment, since the bobbin can be attached and detached by the swinging mechanism and the meshing mechanism of the chain and the sprocket 11 is used for the driving device thereof, the parts configuration of the device is simplified and the reliability is reduced. Is improved.

Further, even if the weight of the bobbin is large, the risk of falling is extremely small and the safety is improved.

3 and 4 are front views of an automatic bobbin attaching / detaching device showing another embodiment having a different configuration.

In the embodiment shown in FIG. 3, a cover 12 for covering the container 6 is attached to the end of the swinging member 3 so as to prevent the bobbin 1 from falling out of the container 6 even if the container 6 is tilted by 45 ° or more. There is.

Further, in the embodiment shown in FIG. 4, an under roller 13 is provided inside the container 6 so that the electric wire 14 wound around the bobbin 1 can be pulled out while the bobbin 1 is accommodated in the container 6.

Further, the under roller 13 can be moved toward the center of the bobbin 1, and the size of the bobbin 1 can be adjusted steplessly to some extent.

[Advantage of the Invention] According to the present invention, it is possible to obtain an automatic bobbin attachment / detachment device that solves the problems of the prior art, simplifies the component structure, and improves reliability and safety.
