Description

DETAILED DESCRIPTION OF THE INVENTION The present invention collects the roll core of a roll of a wide magnetic tape to be processed into a magnetic tape, and attaches the roll to a roll holding arm. The present invention relates to a delivery device, and aims to provide a device that can easily and accurately perform the above series of operations.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes an original fabric roll holding stand having a roll holding surface 2 recessed on the upper surface, 3 an elevating movable body, and 4 an unwinding device, which has an original fabric roll holding arm 5. ing.

The raw roll holding table 1 is movable, for example, using rails 6 as a guide, from a position W shown by a solid line in FIG. 8, and a roll core holding arm 9 is provided at the front end.

The elevating and lowering movable body 3 follows a reciprocating drive mechanism (not shown) such as a hydraulic device stored in the storage section 10, and moves the above-mentioned fabric roll holding arm 5 from a predetermined position Y shown in the figure. It is possible to move along the guide groove 17 to a position Z corresponding to one end of and return. The body also has an elevating body 11 that can be raised and lowered by an elevating mechanism (not shown) such as a hydraulic device housed within the body.

The unwinding device 4 sequentially feeds out the magnetic tape material a from the material roll A held by the chuck body 12 set at the other end of the material roll holding arm 5, and Fabric a is machine 1
3, and is sent to, for example, a calendering device that applies a mirror finish to the surface of the raw roll a. Also, the original fabric roll holding arm 5
A roll core B made of, for example, a cardboard tube is held at one end by a chuck body 12. This roll core B was initially a raw roll A with the raw fabric a wound around its outer periphery, but at the other end of the raw roll holding arm 5, the entire raw fabric a was unwound and the roll core B was rolled. When only B remained, the original roll holding arm 5 rotated 180 degrees and moved from the other end to the one end. The above chuck 1
2 is actuated in the directions of arrows 2a and 2b by a driving body 15 such as an air cylinder.

The operation of the above configuration will be described.

First, at the W position shown in FIG.
is held, and the original fabric roll holding table 1 is pushed and moved to the X position using the rail 6 as a guide to obtain the state shown in FIG.

Next, the reciprocating drive mechanism housed in the storage section 10 is operated to move the elevating movable body 3 in the direction of the arrow 3a to the position shown in FIG. position (Z position in FIG.
is moved in the direction of arrow 2b shown in FIG.
The upper receiving surface 16 of the roll core B released from the chuck body 12 is received and held.

Once the roll core B is held on the surface of the elevating body 11, the elevating body 11 is lowered once as shown by the imaginary line in FIG. The body 3 is moved and returned to the predetermined position shown by the solid line (Y position in FIG. 1), that is, to the point where it is straddled by the web roll holding table 1. During this return, the elevating body 11
The roll core B held on the upper surface of the roll core B hits the front end surface of the original roll holding stand, falls onto the upper surface of the roll core holding arm 9, and is recovered.

When the collection of the roll core B is completed, as shown in FIG. 3d, the elevating body 11 is raised to lift both the original fabric roll holding table 1 and the original fabric roll A. next,
In the above-mentioned lifted state, move the elevating movable body 3 by arrow 3d.
direction, but it does not reach the position corresponding to one end of the original roll holding arm 9 shown in FIG. 3e. At this position, the chuck body 12 is moved in the direction of the arrow 2a in FIG. 2 to fit its tip into the roll core B of the original fabric roll A, thereby gripping the original fabric roll A.

Once the original fabric roll A is gripped, the elevating body 11
The original fabric roll holding table 1 is lowered to the position shown by the imaginary line in FIG. The state is returned to the state shown by the solid line, that is, the initial state in which the wheels 8 of the original roll holding stand 1 fit into the rails 6.

Thereafter, the original fabric roll holding stand 1 is moved to the W position shown in FIG. 2 using the rail 6 as a guide, and the next original fabric roll A is held on its roll holding surface. Further, the above-mentioned original fabric roll A held at one end of the original fabric roll holding arm 5 is unwound when all the preceding original fabric rolls A at the other end of the original fabric roll holding arm 5 are unwound. By turning the anti-roll holding arm 5 by 180 degrees, it moves to the other end, and at the same time, the roll core B of the preceding raw roll A moves to the one end and waits until the next collection.

In order to carry out such an operation, a known detection means is appropriately used and a control means is used to perform appropriate control.

As described above, the present invention collects the roll core B at one end of the original fabric roll holding arm 5, and receives the original fabric roll A at the one end of the original fabric roll holding arm 5 from which the roll core B has been collected. This has the effect of making it easier and more accurate to perform a series of tasks.

Claims (1)

[Claims] 1 a reciprocating drive mechanism that reciprocates from a predetermined position to a position corresponding to one end of the original fabric roll holding arm 5 of the unwinding device 4; a means for raising the elevating body 11 at this position; an elevating movable body 3 having a receiving surface 16 for receiving the roll core B held at one end of the anti-roll holding arm 5;
As the elevating body 11 rises, the elevating movable body 3 holds the raw fabric roll A on its upper surface across the elevating movable body 3 and has a roll core holding arm 9 at the front end. After receiving the roll core B on the receiving surface 16, the elevating body 11 is lowered,
It returns to the inside of the original fabric roll holding table 1, and by this returning operation, the roll core placed on the receiving surface 16 of the elevating movable body 3 is brought into contact with the front end of the original fabric roll holding table, and the roll core is removed. The original fabric roll holding table 1 is transferred to the holding arm 9, and further lifted by the rise of the elevating body 11, and moved together with the elevating movable body 3 to a position corresponding to one end of the original fabric roll holding arm 5. Original fabric roll A held on the top surface
A device for collecting a roll core and delivering a raw roll, characterized in that it is equipped with a control means for controlling the roll core to be delivered to one end of the raw roll holding arm 5 and returned to a predetermined position together with the elevating movable body 3. .
