Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a yarn bobbin handling device for mounting or withdrawing a yarn bobbin on a vertical or horizontal support in a completely independent manner.

[0002]

2. Description of the Related Art A device of the above type, for example a bobbin, is
For removing them from temporary storage means or from textile machines and lowering them onto a roller table at a transport member movable along one or more guides (eg a carriage movable along an elevated guide) or at floor level. Devices of the above type used have long been known. Some of these devices (eg take-off doffers) have bobbins
Removed from a support on a vertical or horizontal axis (relative to the plane on which the device is moved or the plane on which the textile machine is located),
It can also be mounted or mounted on another support, also on a vertical or horizontal axis.

The known devices also have one or more support members for one or more bobbins. For example, a take-off doffer comprises a plurality of support members (also known as mandrels) associated with a body that is movable along a columnar structure and that rotates about an axis perpendicular to the structure.

[0004]

Known devices of the type described above include a pusher member associated with each support member or mandrel. The pusher removes the bobbin mounted on the mandrel from the mandrel when the bobbin must be mounted on another support. However, this device is relative
Any bobbin placed on the support cannot be independently removed. As a result, if the support (10) on which the bobbin is placed (eg, the mandrel of a textile machine) is also not equipped with a pusher member, the bobbin is automatically placed on the mandrel of such known device. I can't. In this case, the placement can only be done manually.

Accordingly, it is an object of the present invention to provide a very compact and versatile device for removing bobbins from vertical or horizontal axis supports or for mounting such bobbins on those supports. Is to provide
This device can perform both the mounting and dismounting operations simultaneously and automatically for up to four mandrels simultaneously.

In particular, it is an object of the present invention that it can be used reliably in such a way that it can be used in place of a similar known device in an already operating textile machine. To provide a device of the above type which is of no greater size than that of the device.

[0007]

These and other objects, which will be apparent to those skilled in the art, are achieved by claim 1.

[0008]

The invention will be more apparent from the accompanying drawings, which are presented by way of non-limiting example.

Referring to the drawings, the device of the present invention is shown generally at 1 and comprises a columnar structure 2. The columnar structure 2 is movable in a known manner along the guide 3 arranged on the surface 4, and is provided with the case 5. The case likewise rotates in a known manner about an axis 6 on which the case is attached to the structure. The case carries, for example, four mandrels 7 or support members for a bobbin 9 to be removed from a support 10 of a temporary storage means or from a textile machine not shown. The case 5 can be moved toward the support 10 by an ordinary motor means (not shown).

Each mandrel 7 has a pusher member 12
And a detachment member 13 for detaching the yarn bobbin 9 from the corresponding support 10. The pusher member 12 and the removal member 13 are in sliding contact with a support element 15 arranged between the mandrels 7, which support element 15 guides the movement of the member towards the support 10. is there.

More specifically, each pusher member 12
Comprises an arm 18 vertically projecting from a tubular element 19 which is slidably guided around a guide member 20 associated with a frame 21 of a case 5 with two opposite end plates 21A and 21B. There is. Pusher member 12
Are torsionally fixed with respect to the guide member 20. The guide member 20 carries, near one of its ends 23, a spring 24 which acts as a restriction stop for the movement of the tubular element 19 along the guide member.

The tubular element 19 is associated with the support 25 via a support bush 25A, which supports the member 2
Supports 6. The member 26 is guided in the cavity or guide 27 of the support element 15 and cooperates with a driven wheel 30 provided at one end 29 of the element 15 and an electric motor member 32 fixed to the plate 21A of the case 5 and a drive wheel 31. Operatively cooperates with a belt member (or similar transmission member) 28 disposed between and. The movement of the belt member (or simply belt) 28 causes the support 25 to slide along the support element 15 and thus the arm 1
8 is moved along the corresponding mandrel 7. The support 25 carries at its free end 35 a mechanical stop element 36 adapted to cooperate with a corresponding stop (not shown) associated with the support element 15. The support 25 also carries a scraping element 38 which keeps the guides or cavities 27 of the support element 15 free of dust and the like.

As mentioned, the pusher member 12 is torsionally fixed with respect to the guide member 20. This guide member 20 is associated at its end 23 with the connecting rod 40. The connecting rod 40 is hingedly attached at its end 40A to a pneumatic actuator 41, which is arranged in the case 5,
At its end 42 it is associated with the frame 21 of the case (specifically with the plate 21A) and at 43 it is hingedly attached to said frame. Actuation of the actuator 41 (provided with a piston 41A movable in a cylinder 41B hingedly attached to the case 5 at 43) causes the guide member 20 to be parallel to its axis W (the longitudinal axis N of the mandrel 7). ), So that rotation of the tubular element 19 (in the support bush 25A of the support 25) and corresponding arm 1
8 rotations are produced. In this way, this arm 1
8 can approach and withdraw from the corresponding mandrel 7.

The arm 18 can assume two working positions, one shown, near the plate 21B, and the other near the end 7A of the mandrel along the corresponding mandrel 7. . This end is provided with a known gripper 50 which locks the bobbin mounted on the mandrel and is operated by a normal pneumatic actuator 51 located in the case 5.

Each detachment member 13 comprises an arm 55 arranged at the end of a tubular support or tubular element 56 which is slidably guided around a guide member 57 associated with the frame 21. Element 56 and arm 55 are torsionally fixed with respect to member 57. The member 57 also has a connecting rod 61 hingedly attached at one end 63 to a pneumatic actuator 64 similar to the actuator 41 described above.
It has an end 60 for cooperating with (which is similar to the connecting rod 40). The actuator 64 includes a piston 64A movable in a cylinder 64B hingedly attached to the frame 21 at one end 65.

The member 57 is provided with a limit stopper spring 67 near its end 60, is supported by a support (not shown) similar to the support 25, and is driven by an electric motor 73 which cooperates with the frame 21. It is movable along the support element 15. The member 57 can rotate about its axis F in a support 71 associated with the support, which rotation results in rotation of the support 56 and the arm 55 about said axis. The axis F is the mandrel 7
Is parallel to the axis N of.

The movements of the elements 25 and 70 are carried by the frame 21 and controlled by conventional control members such as an encoder 75 (as shown in FIG. 3) near the motors 32 and 73. Should be inscribed.

The arm 55 can take two operating positions. That is, one is the end 7A of the corresponding mandrel (having similar characteristics to the mandrel already described).
And the other is protruding away from the edge. This other working position is separated from said end by at least a distance equal to the length (or height) of the usual yarn bobbin 9. Thus, during the use of the device according to the invention, after bringing the mandrel 7 close to the bobbin 9,
Actuating the motors 73 (or a single motor driving all of the members 13) causes each arm 55 to
Move away from the end 7A of the corresponding mandrel 7. This arm moves over a bobbin 9 arranged on a support 10. This movement is controlled by the encoder 75 or other known control means.

Thereafter, each actuator 64 is operated to move each arm 55 to a position close to the longitudinal axis of the bobbin. Then, the motor 73 is operated again to return each arm 55 to the vicinity of the corresponding mandrel 7, and the bobbin is mounted on the mandrel.

In this way, the bobbin is automatically taken out from the support 10 that has been arranged and mounted on the mandrel 7. This is done without the bobbin being pushed onto the mandrel by any pusher member associated with the support 10.

The bobbin is removed from the mandrel by the pusher member 12. In this case, assuming that the mandrel 7 is in front of the bobbin-free support 10, the motor 32 is activated and, in the manner already described, the arm 18 (by a corresponding actuator, near the longitudinal axis of the bobbin). , Rotated appropriately), pushes the bobbin 9 onto the support 10.

While one embodiment of the present invention has been described, other embodiments are possible in light of this specification and are to be considered within the scope of the present invention.
