In the winder in which each web 5 is wound by the core 7 set between the pair of winding drums 6, both ends of the plurality of cores 7 linearly arranged between the winding drums 6 are arranged along the support column 8. There is a shaftless type in which the web 5 is wound by being supported by a pair of chuck devices 9 which are slidably provided.

In the above winder, when the winding diameter of the web 5 wound around the core 7 reaches the set winding diameter, the web roll 10 wound around the web is wound onto the winding drum 6.
After being discharged downstream, the next core 7 is supplied between the pair of winding drums 6 to continue winding.

As an automatic feeder for the cores 7 between the winding drums 6, cores having different lengths are stored in a plurality of core storage containers 11 and the cores required for winding are supported from the core storage containers 11. Take out one by one on the part 12,
Every time the core 7 is taken out from the core supporting portion 12, the core 7 is sent out to the core loading portion 13 provided in the discharge path of the web roll 10, and the required number of cores 7 are aligned in the core loading portion 13, and then the cores 7 are paired. Japanese Patent Laid-Open No. 2-193847 discloses a method in which the material is sent out between the take-up drums 6.

[0005]

By the way, in the above-mentioned automatic core feeding device, the core 7 in the core container 11 is
Since the cores are taken out one by one from the lower part of the core storage container 11, when there are many cores 7 in the core storage container 11, the cores 7 interfere with each other due to interference between the cores 7.
Often forms a bridge within 1
There was the inconvenience that it was not possible to take out the books one by one.

It is a technical object of the present invention to solve the above-mentioned inconvenience and to provide a take-up device for take-up cores that can take out cores in a container one by one.

[0007]

In order to solve the above-mentioned problems, in the present invention, a core holder capable of holding and releasing a core in a core container, and the core holder is moved vertically. Z-axis linear slide device,
The Z-axis linear slide device is configured to include an X-axis linear slide device that reciprocates in the direction orthogonal to the axis of the core held by the core holder.

Here, the core holder may be one that sucks the core by a suction plate, or one that holds the core by a pair of holding claws that are opened and closed by a cylinder.

[0009]

In the take-out device having the above structure, the core holder is moved to a designated position on the core container by the operation of the X-axis linear slide device, and the core holder is operated by the Z-axis linear slide device. Then, the core in the core container is held and then raised, and the core is conveyed to a predetermined position outside the core container by the operation of the X-axis linear slide device, and the holding is released.
