Description

An object of the present invention is a comb machine for a spinning preparation line.

In the spinning preparation line, after the first step of opening and cleaning the fibers, carding is performed by a carding machine where the fibers are in the form of a sliver.

After several separate slivers have been combined with a wrap winder to obtain the wrap, the fabric or sliver is combed to obtain a sliver in which the fibers are highly parallel cleaned. Combed by.

In more modern machines, the basic comb movements that proceed with each other at a rate of 500-550 strokes / minute are:
-Steps to supply textiles intermittently,
-With a rotating comb, with the nippers closed, comb the heads of the incoming bundle,
-During the return rotation, the step of overlaying and joining the bundle heads to the already combed fabric of the cycle before it was properly returned by the removal rollers,
-With the nippers open, use a straight nipper comb to comb the tail of the bundle,
-The step of advancing the bundle combed by the removal roller during the previous rotation.

Therefore, the removal rollers have alternating rotational movements. Starting with its electric motor, controlling the removal rollers and allowing them to operate alternately, the moving members of the removal rollers are one of the most problematic parts of the design and production of comb machines.

In fact, these components must withstand very dynamic stress as they undergo repeated stops and restarts. As the speed of the machine increases, the rotational speed increases proportionally in one direction and on the other side of the removal roller. Therefore, dynamic stress becomes more and more burdensome.

These components also have a significant amount and at least 30% to 40% of the final cost of the comb machine.

There is a patent document describing a solution for a comb machine with a unidirectional rotary motion of a removal roller. For example, consider Reference European Patent Publication No. 1553219A1.

However, when the applicant replicated the solution depicted in Document European Patent Publication No. 1553219A1 for experimental purposes, it was confirmed that the combing results were not satisfactory in terms of the quality of the obtained sliver.

Further embodiments of comb machines with unidirectional moving removal rollers are described in Italian Patent Application No. 1020180000001987, represented by the applicant.

Finally, there is a further solution for comb machines controlled by electronically controlled electric motors in order for the removal rollers to obtain alternating rotational movements. In this case, the complicated mechanical operation member of the removal roller is not required.

However, these solutions have considerable drawbacks, primarily with respect to energy consumption, heat of electronic motors, duration of these motors and response of motion control.

(First Embodiment (FIGS. 1 to 10))
The comb machine according to the present invention includes a fixed frame and a plurality of comb heads, and each comb head includes nippers 4 supported by the fixed frame.

The nippers 4 include a lower jaw portion 6, an upper jaw portion 8, and a straight comb 10 that is generally integrated with the lower jaw portion 6.

Further, the nippers 4 include a supply roller 12 that is supported by the lower jaw portion 6 and can rotate in a commanded and intermittent manner.

The comb head further includes at least a pair of removal rollers downstream of the nippers 4.

For example, just below the nippers 4, a continuous rotation operation (constant or variable but inverted) is performed so as to pull the extension part of the woven fabric protruding from the chin part, remove the bundle from the woven fabric, and bring it downstream. It is preferable that there are a pair of 20'removal rollers 20a', 20b' that are superposed by pressure welding to provide (impossible speed).

According to this embodiment, downstream of the pair of 20'removal rollers 20a'and 20b', the upper auxiliary roller 20a and the lower auxiliary roller 20b which is generally connected to the upper auxiliary roller 20a by pressure and thereby driven by rotation are provided. , There are one-to-two auxiliary rollers.

If a virtual entrance plane P1 that is in direct contact with the two auxiliary rollers 20a and 20b is defined on the upstream side between the auxiliary rollers 20a and 20b, the inlet port 22 is between the entrance plane P1 and the side surfaces of the auxiliary rollers 20a and 20b. Is identified by. If the exit plane P2 is similarly defined on the opposite side, i.e. downstream, the exit port 24 is instead identified.

Auxiliary rollers 20a, 20b have a continuous rotational motion that pulls the stretch of the fabric provided by the removal rollers 20a', 20b', removes the bundle from the fabric, and brings it from the inlet port 22 to the outlet port 24. (Constant or variable but not reversible).

The auxiliary rollers 20a and 20b have the same peripheral velocity Vd and their respective angular velocities Wa and Wb.

Further, the comb head is installed in front of the outlet port 24 of the auxiliary rollers 20a, 20b and translates, for example, and collides the bundles coming out of the auxiliary rollers 20a, 20b, especially with respect to the collision area 29 of the main surface 28. It comprises a main device 26 with an operable main surface 28.

The main surface 28 is provided with a main velocity Va, especially in the collision region 29.

For example, the main device 26 provides continuous rotational operation (constant or variable speed, but in any direction) clockwise or counterclockwise and is located downstream of the auxiliary rollers 20a, 20b. A main roller 30 facing the exit port 24 in front of them.

The main roller 30 has a side surface 30'that constitutes the main surface 28 of the main device 26.

The side surface 30', that is, the main surface 28, is airtight. In other words, no suction holes or ports are provided on the surface.

The main roller 30 generally has a diameter larger than the diameter of the main removal rollers 20a and 20b and a peripheral velocity Vm corresponding to an angular velocity Wm.

The peripheral speed Vm of the main roller 30 is lower than the peripheral speed Vs of the auxiliary rollers 20a and 20b.

For example, the peripheral speed Vm of the main roller is 20-40% of the peripheral speed Vs of the auxiliary roller, for example 25-35%, for example 28 to 32%, for example about 30%.

Preferably, if a virtual third plane P3 that is tangent to the auxiliary rollers 20a and 20b and passes through a contact line between them is defined, the rotation axis 30 ″ of the main roller 30 is set on the third plane P3 by the main speed Va. It is arranged below or above, that is, in the direction of rotation of the main roller 30 facing the outlet port 24.

For example, in the description of FIG. 2, the rotation direction of the main roller 30 facing the outlet port 24 is downward, and the rotation axis 30 ″ of the main roller 30 is arranged below the third plane P3.

In other words, the third plane P3 defines the exit direction of the bundle S'from the exit port 24.

The comb head further comprises a transfer device 40 that provides a bundle of fabrics that leaves the main surface 28 of the main device 26 or the side surface 30'of the main roller 30 as will be seen hereafter. The bundle moves to the transfer area 42 of the transfer device 40.

The transfer device 40 preferably engages with the main surface 28 of the main device 26. For example, the transfer device 40 is in direct contact with the side surface 30'of the main roller 30 along the engagement line L.

The transfer device 40 is preferably flat in the vicinity of the engagement line L.

Further, the transfer area 42 of the transfer device 40 is preferably flat.

If a virtual center lower plane P4 that passes through the axis of rotation of the lower auxiliary roller 20b and the main roller 30 is defined, the center lower plane P4 intersects the side surfaces of the lower auxiliary roller 20b and the main roller 30 and moves onto the transfer device 40. To this end, we define a lower passage 32 that is crossed by a bundle that is removed from the main surface 28, i.e. from the side surface 30.

The virtual center upper plane P5 is also defined through the rotation axes of the upper auxiliary roller 20a and the main roller 30. The central upper plane P5 intersects the side surfaces of the upper auxiliary roller 20a and the main roller 30 to define the upper passage 34.

The lower passage 32 through which the bundle removed from the main surface 28, i.e. the side surface 30'is passed to move to the transfer device 40 is narrower than the upper passage 34.

In other words, the bundle removed from the main surface 28, i.e. the side surface 30'to move to the transfer device 40, was made by the lower auxiliary roller 20b and the upper auxiliary roller 20a with respect to the main surface 28, i.e. the side surface 30' of the main device 26. Cross the narrow passage (defined by the exit passage) between the two passages.

The transfer region 42 is arranged in front of the lower passage 32, for example, upstream of the engagement line L, in relation to the direction of the main speed Va or the peripheral speed Vm of the main roller 30 of the engagement line L.

Further, it is preferable that the transfer device 40 is operable, that is, has a predetermined support speed Vs in the engagement region 42.

For example, a comb machine comprises a conveyor belt 50 that preferably completes a closed path outside the main roller 30 and forms the transfer device 40 at least in part.

The speed of the belt 50 in the engaging region 42 corresponds to the supporting speed Vs and follows the peripheral speed of the main roller 30 of the main speed Va or the engaging line L.

For example, in the engagement line L, the belt 50 is in direct contact with the main surface 28 or the side surface 30'of the main roller 30.

The belt 50 has at least one conversion roller, preferably a pair of 60 conversion rollers 60a, 60b and preferably a main roller, arranged, for example, under the auxiliary rollers 20a, 20b to define its own closed path. It is preferred that it be wound around an additional roller 60c located downstream of 30.

The comb head may further include a pair of 70 pressure rollers 70a, 70b that are press-bonded through which the combed fabric W carried by the transfer device 40 is flattened and passed through to normalize the thickness. preferable.

It is preferable that at least one 70b of the pressure rollers 70a and 70b is the same as the additional roller 60c around which the belt 50 is wound.

In addition, the comb head is a press-bonded one-to-80 end roller through which the fabric W passes, preferably after being flattened and normalized to exit the comb area, and after its own trajectory has been changed. It is preferable to provide 80a and 80b.

It is preferable that at least one 80b of the end rollers 80a and 80b is the same as the additional roller 60c around which the belt 50 is wound.

Finally, according to the illustrated embodiment, the pressure roller 70a and the end roller 80a are outside the path of the belt 50 and are press-coupled with an additional roller 60c around which the belt 50 is wound, together with a bow-shaped locus. Is defined.

The comb head is more commonly located under the nippers 4 and comprises a circular comb 90 that always provides continuous rotational movement in the same direction at a constant or variable speed.

The comb machine comprises one or more electronic motors and a plurality of transmission members configured to transfer motion from the at least one electronic motor to the components described above.

In particular, the nippers have a front-back movement, and the jaw portion has an opening / closing movement at a predetermined operating speed.

Further, in the nippers 4, the jaws 6 and 8 are located proximal to the removal rollers 20a'and 20b', and the jaws 6 and 8 are located distal to the removal rollers 20a' and 20b'. Back and forth movements between certain rear restricted positions are provided alternately.

At the same time, the jaws 6 and 8 are provided with alternating opening and closing operations, while the supply roller 12 is provided with an intermittent rotational operation that allows a piece of fabric to be released from the nippers.

When the nippers are in the forward restricted position, the comb portion of the circular comb combs the head of the piece of fabric protruding from the chin, which head is taken between the removal rollers 20a', 20b' and the roller 20a'. , 20b'rotation causes tearing of the bundle S'carried from upstream to downstream and transferred to the auxiliary rollers 20a, 20b (FIG. 2).

For the bundle S', the head portion Hs'and the tail portion Ts' are defined. The tail portion Ts'of the bundle S'is combed by the straight comb 10.

The continuous rotation of the auxiliary rollers 20a and 20b at the speed Vd causes the bundle S'from the inlet port 22 to the outlet port 24 until the head portion Hs'collides with the main surface 28 of the main device 26 or the side surface 30' of the main roller 30. Let it proceed (Fig. 3).

Due to the advantage of the ratio of the peripheral speeds Vd of the removal rollers 20a and 20b and the main speed Va, which depends on the mode in which the bundle S'collides with the main surface 28, the head portion Hs'of the bundle S'is the main surface 28 or the main roller. The tail portion Ts'is arranged on the side surface of the upper auxiliary roller 20a while being arranged on the side surface 30'of 30 and guided to a narrow passage, that is, the lower passage 32. Between the head portion Hs'and the tail portion Ts', a bay portion R'is formed between the upper auxiliary roller 20a and the main roller 30, that is, on a wide passage, that is, on the side surface of the upper passage 34 (FIG. 4).

Gradually, the bundle S'moves from the head portion to the tail portion on the main surface 28 of the main device 26 or on the side surface 30'of the main roller 30 (FIG. 5), thereby being carried.

During pulling, the bundle S'is not subject to any flow of suction air that adheres to the main surface 28.

The head portion Hs of the bundle S'begins to be removed from the main surface 28 or from the side surface 30'of the main roller 30 and passes through the lower passage 32 toward the transfer region 42 of the transfer device 40 (FIG. 6).

Gradually, the bundle S'has a head portion Hs'colliding with the transfer device 40 and gradually advances, while the tail portion Ts' is removed from the main surface 28 or the side surface 30'of the main roller 30. Further bundles S'' are moved to the auxiliary rollers 20a, 20b by the removal rollers 20a', 20b'(FIG. 7).

The additional bundle S ″ has a head portion Hs ″ and a tail portion Ts ″. Meanwhile, the head portion Hs of the bundle S'is driven by the transfer device 40.

Like the bundle S ′, the head portion Hs ″ of the further bundle S ″ is guided by the main device 26, that is, the main roller 30, and collides with the tail portion Ts ′ of the bundle S ″ (FIG. 8). The head portion Hs of the bundle S'continues to be driven by the transfer device 40.

The head portion Hs ″ of the further bundle S ″ crosses the tail portion Ts ′ of the bundle S ″ by the overlapping portion S * (FIG. 9). The head portion Hs of the bundle S ″ continues to be pulled by the transfer device 40, while the additional bundle S ″ forms a bay portion R ″.

Gradually, the overlapping portion S * is removed from the main surface 28 or the side surface 30'of the main roller 30 and moves across a narrow passage, i.e., the lower passage 32, into the transfer area 42 of the transfer device 40.

By superimposing the head portion Hs ″ of the further bundle S ″ on the tail portion Ts ′ of the bundle S ″, the combed and continuous sliver W is formed and carried by the transfer device 40.

Note that for clarity purposes, the head portion Hs ″ of the additional bundle S ″ traverses the tail portion Ts ′ of the bundle S ″, but is below it. That is, it is placed below this, as is evident for the combed fabric W passing over the transposition device. This improves the transportability of the sliver on the transfer device, as the head portion Hs ″ of the additional bundle S ″ tends not to rise above the tail portion Ts ′ of the bundle S ″.

The combed woven fabric W first passes through the engagement wire L, passes between the main roller 30 and the transfer device 40, and undergoes the first compactification (consolidation, compression).

Next, the combed fabric W passes between the compact rollers 70a and 70b and then exits the comb region through the end rollers 80a and 80b.

According to a preferred embodiment, the comb machine according to the invention is, for example, for a single circular comb shaft for each circular comb, a single upper and lower removal shafts for removal rollers, and an auxiliary roller.
