In Figure 1,
Reference numeral 1 indicates the entire packaging machine using a reel 2 of tape material. The buffer magazine 3 is arranged above the packaging machine 1 and is adapted to contain a plurality of reels 2 arranged side by side with respect to the alignment axis. The buffer magazine 3 is provided with a conventional transport device 4 for advancing the reel 2 and moving the leading reel to the removal position 5. Furthermore, the reel 2 is guided by lateral shoulders, which are not shown.

The reel 2 is located at the entrance of the buffer magazine 3 and is loaded onto the buffer magazine 3 by a loading device 6. A device 7 for changing the reel 2 is provided at the outlet of the buffer magazine 3. The reel 2 replacement device 7 is disclosed in Japanese Patent Application No. 2-4
The type described in No. 02792 is desirable,
A first position with a reel holder head at one end to receive the reel to be transferred to the packaging machine 1;
It has an arm 8 which is rotatable between a second position in which the reel 2 is normally wound and unrolled.

[0009] The upper end of the column 9 in the loading device 6 adjoins the buffer magazine 3, and a lifting element 10 for lifting the reel 2 is movable on the column 9 in the longitudinal direction. The lift element 10 is provided with a support 11 shaped to accommodate a vertically arranged single reel 2 . Furthermore, the loading device 6 has an actuating device 12 for rotating the support around the column 9 between the lower position 13 for receiving the reel to be loaded and the upper position 14 for transporting the reel 2 to the buffer magazine 3. have

The support 11 of the lifting element 10 is conveyed to the lower position 13 by a track 15 on which the reels 2 are arranged side by side. The track 15 has a fork-like member adapted to engage adjacently with the column 9 so as to place the first reel of the row indicated by the number 2a on the support 11. As shown in Figure 2, the struts 9 are tubular, preferably cylindrical.

A threaded shaft 16 rotatably mounted within the column 9 is coaxial with the column and is rotatable by a drive 17 provided at the upper end of the column 9. The internally threaded element 18 is connected to the threaded shaft 16 and comprises a radial arm 19 guided through an opening 20 provided longitudinally relative to the column 9 . The ends of the arms 19 support the ture-type supports 11 on the outside of the struts 9.

The opening 20 communicates with a circumferential portion 21 extending approximately 180° in the shape of an arc near the upper end of the column 9. It communicates with another longitudinal section 22 extending downwardly by a length. The collar 23 is attached to the column 9 above the circumference 21 of the guide opening and is slidable in the axial direction by actuation of an actuator 24 fixedly attached to the column 9. A pair of protrusions 25 and 26 are provided at a lower position of the collar 23.
is provided, and the protrusion is located below the collar 23.
The circumferential guide 21 is cut off so as to be continuous with the longitudinal guides 20 and 22.

The collar 23 constitutes the actuating device together with the circumferential guide 21 and rotates the support 11 about the column 9. The operation of the device according to the invention will now be described. First, it is assumed that the support 11 is located at the receiving position 13 at the base of the column 9. In this position, the track 15 carrying the reel 2 is placed adjacent to the column 9 so as to place the first reel 2a on the support 11.

The lift element 10 is then actuated to move the support 11 upwardly so as to remove the reel 2a from the track 15. As the support 11 is moved by rotation of the threaded shaft 16, the internally threaded element 18 guided vertically along the opening 20 undergoes a translational movement. At the upper end of the guide 20, an arm 19 carrying the support 11 carrying the reel 2a rotates angularly along the circumference 21 of the guide in unison with the screw 16. The support 11 is thus rotated 180° and directs the reel towards the buffer magazine 3.

It should be noted that the support 11 is now further above the upper position 14 and by changing the direction of rotation of the threaded shaft 16 the support 11 is lowered to the upper position 14. For this purpose, the collar 23 is
Lowered axially by the actuator 24, the projection 26 of the collar 23 engages the circumferential guide 21, allowing the arm 19 of the support 11 to be lowered into the longitudinal guide 22.

After removing the reels loaded in the buffer magazine 3 by the conveyor element 4, the above-described operations are repeated in reverse. Thus, by means of a known control device (not shown), the direction of rotation of the screw 16 is reversed and the empty support 11 is removed.
Lift it further above the upper position 14. The support 11 is then rotated by 180° along the circumferential guide 21 by lifting the collar 23 by the actuator 24 .

After the direction of rotation of the screw 16 is reversed by the aforementioned control device (not shown), the support 11 is moved to the guide 20.
At this time, the collar 23 is lowered and the support 1 is moved by the protrusion 25.

It has a section 27a and is inserted onto the support column 9 through the opening so as to be slidable in the axial direction. In the illustrated example, the struts 9 are tubular in shape and have a square cross section. A space 28 for receiving a disk 29 is formed at a lower position of the plate 27, the disk has external teeth 29a, and the plate 27 is closed downward by a ring 30. plate 27,
Suitable rolling elements or bearings 31, 32 are inserted between the disc 29 and the ring 30.

A toothed disc 29, also axially bored, fixes a bracket 33 which is slidably guided in an opening 34 provided longitudinally in the column 9. Bracket 33 is reciprocated along guide 34 by suitable drive elements (not shown). The toothed disc 29 engages a gear wheel 35 which is operated about a vertical axis by a motor 36 supported above the plate 27.

As already mentioned, the reel to be loaded is unloaded from the truck 15 and lifted along the support 9 by the sliding movement of the disc 29 guided along the guide 34. After the support has been raised to the upper end of the column 9, the plate 27 carrying the support 11 above the upper position 14 is rotated by the motor 36 so as to rotate the support 11 towards the buffer magazine 3. , in fact the motor 36 is driven by the gear 3 that engages with the fixed teeth 29a of the disc 29.
Rotate 5.

The reel is then lowered into the transfer position by a corresponding lowering of the disc 29. Support 11
The rotation of the plate 27 carrying the is 180°. Naturally, the plate 27 can also be rotated during the upward movement of the lift element. The lowering of the lifting element is carried out in the reverse manner, returning the empty support 11 to the lower removal position 13.

In the embodiment of FIGS. 3 and 4, the actuating device 12, which is of course suitable for rotating the support 11, includes a plate 27 and a motor 36. In the embodiment of FIGS. In conclusion, the device according to the present invention can easily load reels of tape material into the buffer magazine of a packaging machine, and does not require the operator to do anything other than move the trolley that carries the reel to be loaded. do not have.

Furthermore, the device according to the invention has extremely small dimensions, which are in fact limited to the dimensions of the pillars on which the lifting elements of the reel can slide. In practicing the invention, the materials used, shapes and dimensions may vary as desired.
