Is composed of a tiltable and rotatable aligning conveyor (8) for sending all the components to the core tube rack (4) all at once, and a control device for sequentially operating each of these devices in association with the winding operation of the winder.

In this embodiment, two core tube hoppers (6) and (6 ') have two slit widths, so two core hoppers (6) and (6') are installed on the side of the winder (I). As shown in FIG. 1, the tube hopper (6) has an inclined bottom surface and one surface thereof is open, and a drag conveyor (9) is provided inside the tube hopper (6) facing the opening (12). The drag conveyor (9) takes a slightly forward leaning posture and travels in the direction of the arrow shown in the figure. The core tubes in the hoppers (6) and (6 ') have empty cores on the drag conveyor (9). It is hooked on hooks (10) (10 ') mounted at intervals slightly wider than the diameter, and is carried in the direction of the arrow by a driving device (not shown). In addition, (11) is a core tube fall-out prevention plate which covers the front surface from the upper part of the drag conveyor (9), and has the opening (12) in a part thereof. The opening (12) is equipped with a shutter (13) which is opened and closed by an air cylinder, and a bridge (14) which is in communication with the lateral feed conveyor (7) is fixed from the bottom of the opening (12).

Next, the transverse feed conveyor (7) is installed by being extended from the front of the hoppers (6), (6 ') to the machine side of the winder, and a known belt conveyor is applied. A core tube aligning conveyor (8) is provided on the downstream side of the transverse feed conveyor (7). The core tube aligning conveyor (8) is located at the center of the winder body (I) as shown in FIG. It has a tilting center on the line (C-C) and can be tilted in the core tube traveling direction. The structure of the core tube aligning conveyor (8) will be described in more detail with reference to FIG. 4. Although the conveyor body (8 ′) is a known roller conveyor, the number of entrance sides (the side close to the transverse feed conveyor (7)) One roller (1
6) (three in the embodiment) are positively driven by a driving device (not shown), and the following rollers (17) ... Are all simply rotated rollers. The conveyor body (8 ') is supported by the frame (18), and the center of the frame (18) is attached to the fixed frame (F) via the hinge (15).
9), the frame (18) and the conveyor body (8 ')
Are integrally tilted, and by this tilting, the conveyor main body (8 ') has two positions, that is, a horizontal position shown by a solid line in FIG. 4 and an inclined position shown by a chain line. The entrance end of the main body (8 ') has the same height as that of the transverse feed conveyor (7). Further, the conveyor main body (8 ') is not only tilted in the traveling direction as described above but also rotated in a direction orthogonal to the traveling direction. The rotation mechanism is as shown in FIG. (8 ') are two positions symmetrical with the machine center line (C-C), and the hinge (20) (20') on the frame (18).
It is rotatably mounted by the air cylinder (21).
By (21 '), it can be rotated in a direction orthogonal to the flow direction of the conveyor.

Next, the operation of the core tube aligning / supplying device constructed as described above will be described below. Here, the width of the strip slit by the winder is 2 as described above.
Since there are various types, the strips of each width are A and B, and the horizontal arrangement order is, for example, A, A, B, A, B, B. The strip core tube for the A-width strip is housed in the core tube hopper (6), and the strip core tube for the B-width strip is housed in the core tube hopper (6 '). At this time, the above horizontal arrangement order is set on the operation panel (not shown) of the winder. Now, assuming that a rewinding operation is performed by the winder and it becomes necessary to supply the core tube onto the core tube shelf (4),
At this time, a core tube replenishment signal is transmitted from the winder side to the core tube alignment / supply device. In response to the above signal, the core tube aligning / feeding device is activated, and first, the two hoppers (6) and (6 ') operate as follows in accordance with the horizontal arrangement order of the strip width set as described above. .

First, in the corresponding hopper (6) designated by the order setting, the drag conveyor (9) runs, and the core tube in the hopper (6) is hooked (10).
・ Hook at and carry it to the opening (12). Normally, the opening (12) is closed by the shutter (13), but when the core tube arrives at the opening (12), the detecting device appropriately detects it and the traveling of the drag conveyor (9) is performed. Simultaneously with the stop, the shutter (13) is opened, so that the core tube carried by the hook (10) falls on the bridge (14) and is carried out on the transverse feed conveyor (7). Since the lateral feed conveyor (7) is activated by the replenishment signal, the core tube is carried toward the alignment conveyor (8).

Further, the core tube delivery by the hopper (6) is continuously performed by the hopper (6 ') containing the core tube to be arranged next. At this time, the next hopper (6 ') operates at such a timing that the preceding core tube and the next core tube to be delivered next do not interfere with each other on the transverse feed conveyor (7). In this way, when the core pipes are carried out on the transverse feed conveyor (7) in the previously set horizontal arrangement order, the core pipes next pass on the transverse feed conveyor (7) and the alignment conveyer (8). ).

At this time, the aligning conveyor (8) is inclined as shown by the chain line in FIG. 4 so that the entrance side is at the same height as the transverse feed conveyor (7) and the rollers ( Since 16) is positively driven, the core tube is smoothly transferred to the aligning conveyor (8), falls on the roller (17) along the slope, and stops at the final point (22).
Prevents the fall. Further, the core tube which is next fed laterally is similarly transferred to the aligning conveyor (8), falls on the roller (17), hits the preceding core tube, and is prevented from falling. In this way, the required number of core tubes are aligned on the alignment conveyor (8) as shown by the chain line in the figure.

After this alignment is completed, the conveyor main body (8 ') is subsequently tilted by the tilting air cylinder (19) to the horizontal position as shown by the solid line in the figure, and as shown in FIG. ), (21 ') rotate in a direction orthogonal to the longitudinal axis of the conveyor. As a result, the core tubes arranged on the conveyor (8) are simultaneously transferred to the core tube rack (4) of the winder and placed on the core tube rack (4) as shown in FIG. After that, as described above, the tray (5) feeds one line to the winding shaft (3 ′). Needless to say, all of the above operations are sequentially controlled by a controller (not shown).

[0016]

As described above, the core tube aligning / supplying device according to the present invention is provided with a core tube hopper, a lateral feed conveyor, and a tilting device.
It consists of a movable and rotatable aligning conveyor and a control device, and the core tube hopper is provided only for the type of slit width in the winder. From each core tube hopper, the respective cores are aligned in the order in which the strips are arranged side by side. The tubes are sent one after another,
This is transferred to the aligning conveyor via the transverse feed conveyor, and after being aligned in the axial direction on the aligning conveyor, it is placed on the core tube rack all at once. When the core tubes are aligned and aligned side by side,
Since the cores are supplied one after another, the core tube alignment and supply to the core tube rack, which has conventionally been performed manually, can be completely automated. In particular, the transfer of the core tube is performed by tilting the alignment conveyor and
It is carried out by turning, and each is moved at the same height position.
Therefore, they are transferred smoothly and smoothly. For this reason, in the winding operation of winding each strip on the same winding shaft, a remarkable effect for reducing the number of workers and increasing the speed of the operation is achieved.
