Description

METHODS FOR SELECTING THE NEEDLES OF THE DIAL, IN SINGLE-CYLINDER DOUBLE-BED CIRCULAR KNITTING MACHINES, AND DIAL FOR PERFORMING THE METHOD}

The present invention relates to a method of selecting a needle of a dial in a single cylinder double bed circular knitting machine, and to a dial for carrying out the method.

As is known, a single cylinder double bed circular knitting machine includes a needle cylinder having a vertical axis, and a dial coaxially disposed in an upper region with respect to the needle cylinder.

There are a plurality of axial slots on the side of the needle cylinder, and inside each of the plurality of axial slots, the needle is accommodated so as to slide parallel to the axis of the needle cylinder. Each needle is provided with an actuating heel, generally at its end, adjacent its lower end, ie opposite the tip, the actuating heel projecting radially from the side of the needle cylinder and lateral to the needle cylinder. Can be engaged with a path defined by a needle actuating cam facing it. These paths are configured to generate alternating motion along the corresponding axial slot as a result of the rotational movement about the needle cylinder about its own axis with respect to the needle engaging the path, The alternating movement may cause the needle to engage a thread fed to the needle in the feed or drop of the knitting machine to form a knit, or to remain in a stationary position to be excluded from knitting operations in the feed or drop of the knitting machine, or to provide a particular knitted form. Move the needle to

For selecting other needles that are excluded from the knitting operation, each axial slot of the needle cylinder may be selected to select a needle that must be moved to perform the knitting operation on a given feed, or more generally to operate a particular needle differently from other needles. At least one working heel disposed generally adjacent to the axial end of the selector, opposite the needle, in the corresponding selector, below each needle, and in the middle region of the longitudinal extension of the selector. It is provided with one or more selection heel disposed in.

In many cases, the selector may be vibrated on a plane passing through the axis of the needle cylinder to pass from the operating position to the stop position, in which the selection heel and the operating heel at least partially protrude laterally from the corresponding axial slots. In the rest position, the selection heel and the operating heel are stored into corresponding axial slots relative to the operating position. Around the needle cylinder, there is one or more selection devices, just before each feed or drop of the knitting machine along the direction of rotation of the needle cylinder about its own axis with respect to the needle actuating cam, the selection device being the side of the needle cylinder. Facing in the direction, the selection device is provided with a selection member that can engage the selection heel to produce a transition of the corresponding selector from the operating position to the stop position.

Immediately after the selection device, there is a selector actuating cam that can be engaged by the actuating heel of the selector, which is generally not between the actuating device and the feed or drop of the knitting machine and is held in the actuating position by not being engaged by the selecting member. As a result of the engagement of the actuating cam with the actuating heel, these selectors are moved along the corresponding axial slots of the needle cylinder, pushing the needles that lie in the same axial slot to engage the needle in the path formed by the needle actuating cam, This results in picking up the yarn from the feed under consideration and forming a loop of new knit, or in any case acting differently for the needle corresponding to the selector moved to the stop position.

The selector with which the selection member can engage is moved to the rest position, so that the operating heel of the selector does not engage with the operating cam of the selector. Needles located in the same axial slots as these selectors are placed with the working heel of the needle on a path that keeps the needle idle or excludes it from knitting operations in the feed or drop defined and considered by the needle actuating cam. In any case, the operating heel of the needle is placed on a path different from the path engaged by the operating heel of the needle corresponding to the selector held in the operating position.

The return of the selector from the rest position to the actuation position can be achieved by using a selector inherent elasticity or by a spring, or by an extractor placed in front of the selection device along the direction of rotation of the needle cylinder with respect to the needle and the actuating cam of the selector. Can be.

The dials of these knitting machines generally consist of a dial body, the dial body being disc shaped, disposed coaxially with respect to the needle cylinder in the upper region, and can be actuated by rotational movement around the dial itself axis with the needle cylinder. .

On the top of the dial body, there are a plurality of radial slots, each of which receives a needle that can be moved along a corresponding radial slot, and generally at the end of the needle towards the axis of the dial, a radial slot An actuating heel is provided which protrudes from the actuating heel can engage a path defined by a needle actuating cam facing the top surface of the dial body in the upper region.

These paths are formed to produce an alternating movement as a result of the rotational movement around the self-axis of the dial relative to the actuating cam with respect to the needle engaging the path, the alternating movement of which the needle feeds the knitting machine. Or the needle is engaged with the thread fed to the needle in the drop to form a knit, or held in a resting position to be excluded from knitting operations in the feed or drop of the knitting machine, or the needle is moved to provide the shape of a particular knit.

For a knitting machine, the needle and the dial, in each knitting machine, which gives the possibility of selecting a dial needle to move the needle to knit in a particular feed or to perform a particular type of knitting operation for other needles excluded from the knitting operation. It is known to use a selector disposed between the axes in the same radial slot that receives the corresponding needle. In general, the selector is connected to the same needle, and the selector is provided with an actuating heel that is able to engage a corresponding actuating cam facing the dial in the upper region, typically adjacent the opposite end to the end facing the needle. . Such a selector is generally movable and can be vibrated on a plane passing through the dial axis to pass from the operating position to the stop position, in which the operating heel is engaged with the operating cam facing the dial in the upper region. At least in part projecting upward from the corresponding radial slot, in the stationary position, the working heel is stored into the corresponding axial slot relative to the working position so as not to engage the working cam. There is one or more selection devices, just before each feed or drop of the knitting machine along the direction of rotation of the needle cylinder and dial about the needle cylinder and its own axis relative to the cam for operation of the needle and the selector, the selection device being It may interact with the selector to cause a transition of the corresponding selector from the operating position to the stop position.

In some types of knitting machines, in addition to the working heel, a selector is used that has one or more selection heel protruding from the top of the face of the dial when the selector is in the working position. In these knitting machines, the selection device used to select the needle of the dial faces the dial in the upper area and, in the selection device, the selection heel of the selector of the dial to generate a transition of the selector from the operating position to the stop position. It is provided with a selection member that can engage with.

Although the use of a selector in a dial offers the possibility of a full fulfillment of various knitting operations requirements, the execution of the selection of the needle of the dial is more problematic than the implementation of the selection of the needle of the cylinder. This fact arises mainly from the disk-like structure of the dial, which reduces the space between two adjacent selectors because the area where the selection device acts is closer to the axis of the dial. In order to be able to fully use the selectability, it is necessary for the selection device to have time to act differently for two adjacent selectors, so that the speed of rotation about its own axis of the dial does not exceed a predetermined value. Since this value is significantly lower than the rotational speed that the needle cylinder and dial can typically reach, the need to fully utilize the selectability of the needle in the dial conflicts with the need not to reduce the production possibilities of these knitting machines.

The object of the present invention is to achieve a satisfactory compromise between these two requirements, without excessively lowering the rotational speeds of the needle cylinders and dials, and thus without excessively lowering the productivity of these knitting machines. It is to provide a method of selecting the needle of a dial in a single cylinder double bed circular knitting machine, which makes it possible to provide a good selection of the needle of the dial.

Within this goal, the object of the present invention is to provide a way to make various choices and to meet the requirements of the knitting process mainly used in these knitting machines by the high rotational speed of the needle cylinder and dial. To provide.

It is a further object of the present invention to provide a method which makes it possible to carry out a number of choices, especially with regard to knitting operations by rubber knitting.

A further object of the invention is to provide a dial for a single cylinder double bed circular knitting machine for carrying out the method according to the invention.

An operating heel 4a is provided which is arranged adjacent to the longitudinal end of 4), ie adjacent to the end of the needle 4 which is designed to face the axis 2a of the dial body 2. The working heel 4a of the needle 4 protrudes upward from the corresponding radial slot 3 of the dial body 2.

The actuating heel 4a of the several needles 4 arranged in the dial body 2 can be engaged with one or more actuating cams 6 of the needle 4, the actuating cams 6 being the dial body in the upper region. As a result of the rotational movement of the dial body 2 about its own axis 2a of the dial body 2 relative to the actuating cam 6 in a manner known per se and in a manner known per se. Define one or more paths for the actuation heel 4a to actuate 4) along the corresponding radial slot 3.

Preferably, the needle 4 is capable of transferring the stitches from the needle 4 of the dial 1 to the needle of the cylinder, in a known manner, near the so-called transfer type needle, ie near the tip 4b of the needle 4. By means of a needle provided with a spring 7 which defines a path 8 for the needle which is arranged in the needle cylinder to enable it.

The selector 5 is disposed between the corresponding needle 4 and the shaft 2a of the dial body 2, and at the selector 5, an end of the selector 5 facing the shaft 2a of the dial body 2. In the vicinity, an operating heel 5a is provided, and in the middle region of the longitudinal extension of the selector 5, one or more selection heel 5b is provided.

The selector 5 can be vibrated on the radial plane of the dial body 2 to pass from the operating position to the stop position, in which the operating heel 5a and the selection heel 5b at least partially correspond to the corresponding radius. Protruding upwardly from the directional slot 3, in the stationary position, the operating heel 5a and the selection heel 5b are stored into the corresponding radial slot 3 with respect to the operating position.

Preferably, the selector 5 is such that the selector 5 is vibrated on the plane of the arrangement of the selector 5, ie on the plane passing through the axis of the dial body 2.

When the selector 5 is in the operating position, the operating heel 5a of the selector 5 can be engaged with one or more actuating cams 10, which actuated with the dial body 2 in the upper region. Face-to-face and in a manner known per se, as a result of the rotational movement of the dial body 2 about its own axis 2a of the dial body 2 relative to the actuating cam 10, the selector 5 and thus the needle Define one or more paths for the actuation heel 5a to actuate (4) along the corresponding radial slots 3.

In the illustrated embodiment, the actuating cam 6 of the needle 4 which engages the actuating heel 4a of the needle 4 is selected by the needle 4 and thus the selector 5 towards the axis 2a of the dial body 2. The operating cam 10 of the selector 5, which is capable of causing movement of the selector 5 and being engaged by the operating heel 5a of the selector 5, moves away from the axis 2a of the dial body 2. 5) Thus, the movement of the needle 4 occurs, but the cam can be provided differently. For example, the actuating cam 6 of the needle 4 may actuate the actuating heel 4a of the needle 4 which moves the needle 4 and thus the selector 5 in both directions along the corresponding radial slot 3. Can define a path for the actuating cam 10 of the selector 5 to move the needle 4 along the selector 5 to change the path in which the actuating heel 4a of the needle 4 engages. It can be generated simply.

There is at least one selection device 11 above the dial body 2, in which the selection heel 5b of the selector 5 generates a transition of the selector 5 from the operating position to the stop position. And a selection member 12 which can be engaged with the dial body 2, the dial body 2 is a dial body for the selection device 11 in order for the selector 5 to face the selection device 11 at each moment. It can be operated to make a rotational movement about its own axis 2a of (2).

The selection member 12 includes a plurality of selection levers 13 that face the upper surface of the dial body 2 with respect to each selection device 11. The selection levers 13 of each selection device 11 are laterally adjacent and spaced apart from each other along the radial direction with respect to the axis 2a of the dial body 2. Each selection lever 13 can be moved from the operating position to the rest position according to the command, in which each selection lever 13 is adapted to generate a transition of the corresponding selector 5 to the stop position. Selector 5 facing the selection lever 13 at each moment as a result of the rotational movement of the dial body 2 around its own axis 2a of the dial body 2 relative to the selection device 11. Meshes with the selection heel 5b, and in the rest position, each selection lever 13 does not interfere with the selection heel 5b of the selector 5.

The selection lever 13 of the selection device 11, in a manner known per se, can be operated to be passed from the operating position to the rest position or vice versa by means of a programmable electronic actuation and control member. The control member monitors the operation of the knitting machine and operates the selection lever 13 so that the selection lever 13 does not interfere with or interfere with the selection heel 5b of the specific selector 5 as a function of the predetermined knitting program.

Conveniently, in the case of a knitting machine with a plurality of feeds or drops, the selection device 11 is about its own axis 2a of the dial body 2 for feed or drop and also for the selection device 11. It is provided in front of each feed or drop of the knitting machine along the rotational direction of the dial body 2, and the thread for knitting is consumed in the feed or drop.

According to the invention, the dial body 2 is ideally divided into a plurality of sectors 14, 15 arranged sequentially around the axis 2a of the dial body 2, each sector 14, 15. Comprises a predetermined number of radial slots 3, each of the selectors 5 having two selection regions 16, 17 arranged sequentially along the longitudinal extension of the corresponding selector 5. One or more selection hills located in one of the sectors, for example in the radial slot 3 of the sector 14, are located in one of the two selection areas, for example in the selection area 16. A selector 5 having 5b) and arranged in two consecutive sectors, for example in the radial slot 3 of the sector 15, in the other of the two selection areas, for example in the selection area 17. The selector 5 is arranged in the radial slot 3 so as to have one or more selection heel 5b positioned.

In each selector 5, the two selection regions 16, 17 are arranged in the same radial slot 3 of the working body 5b and the dial body 2 and connected to the needle 4. Disposed between the longitudinal ends of (5).

Due to this particular arrangement of the selection heel 5b on the selector 5 and this particular arrangement of the selector 5 with respect to the dial body 2, its own axis 2a of the dial 1 with respect to the selection device 11. The needle 4 of the dial 1 can be selected even at a high rotational speed of the dial 1 to the surroundings.

Preferably, while the dial body 2 passes under the selection lever 13 of the selection device 11 together with the sector 14 or 15 of one of the sectors, also some of the selection levers 13 While performing the selection of the needles 4 arranged in such sectors 14 or 15, that is, some of the selection levers 13 are selected heel 5b of the selector 5 located in such sectors 14 or 15. ) Acts on the selection area 16 or 17 on which the other selection lever 13 of the selection device 11 is arranged, in the immediately following sector 15 or 14 of the dial body 2. It is preset in the working position or the resting position as a function of the selection for (4). In practice, the selection lever 13 of the selection device 11 is selected in the selection area 16 or 17 of the selector 5 disposed in the sector 14 or 15 (selection area in which one or more selection hills 5b are provided). While facing and acting on the selection area 16 or 17, it does not have a selection heel 5b for the other selection area 17 or 16 (the selector 5 disposed in that sector), but of the dial body 2. Another selector lever 13 facing the selector 5 disposed in the immediately following sector 15 or 14 and the select region having the select heel 5b is arranged in the immediately subsequent sector 15 or 14. It is preset at a position that can act on the selector 5.

In the illustrated embodiment, the selection device 11 is provided with eight selection levers 13 in all, four for each of the selection areas 16, 17, and thus in each of the selection areas 16, 17. On the other hand, there are four different possibilities of arrangement for the selection heel 5b, and there is also the possibility of having a plurality of selection heel 5b in the selection areas 16 and 17 of each selector 5, but the selection lever ( The number of 13 and thus the number of possible positions of the selection hills 5b for each of the selection areas 16, 17 can vary according to the requirements.

The selection method of the needle 4 of the dial 1 according to the present invention is as follows.

As described above, the dial body 2 in which the selector 5 is disposed has a needle so that the sectors 14 and 15 of the dial body 2 face the lower area with respect to the selection device 11 at each moment. It is operated to rotate around its own axis 2a of the dial body 2 with respect to the actuating cam 6 of the 4, the selector 5 and the actuating cam 10 of the selecting device 11. In front of each selection device 11, all the selectors 5 in the rest position are moved to their working position by engaging a reset cam of known type, not shown for simplicity, in a manner known per se.

Selection lever 13 of selection device 11 designed to act on selection heel 5b of selector 5 associated with needle 4 to be actuated and to be excluded from feed or drop. ) Is moved to the operating position in advance, so that when the selector 5 passes under the selection device 11, the selector 5 results in the selection heel 5b engaging the one of the selection levers 13. Is moved to the stop position, and the other selector 5 is kept in the operating position. Immediately downstream of the selection device 11, the selector 5, which was held in the operating position, engages with the actuating cam 10 of the selector 5, which causes the selector 5 to have an axis 2a of the dial body 2. By moving in a direction away from, the needle 4 corresponding to the feed or drop under consideration is activated.

Conversely, the selector 5 that has been moved to the rest position does not engage the actuating cam 10 of the selector 5 so that the corresponding needle 4 remains excluded from the knitting operation in the feed or drop under consideration.

As described above, as shown in FIGS. 3 to 6, the sectors 14, 15 of the dial body 2 face a selection facing one of the two selection areas 16 or 17 of the selector 5. Another set of selection levers 13 carried out by the lever assembly 13 and designed to face another selection area 17 or 16 of the selector 5 disposed immediately in the sector 15 or 14, It is preset to select the needle 4 placed in the immediately following sector 15 or 14.

In this way, it is possible to anticipate the operation of the selection lever 13 without interfering with the selection in progress, thereby reducing the time required for selection, thus making it possible to operate the dial 1 at a high rotational speed, In any case it is possible to operate at a rotational speed that does not significantly reduce the productivity of the knitting machine.

When the subsequent sector 15 or 14 is arranged to face the selection device 11 in the downward zone, the selection lever 13 in the operating position is the needle 4 disposed in the preceding sector 14 or 15. In a manner similar to that already described with reference to reference, it engages with the selection heel 5b of the selector 5 associated with the needle 4 which should be excluded from the knitting operation in the feed or drop under consideration, and thus the The selection of the needle 4 proceeds as described above.

In this way, various choices of needles 4 are arranged on the dial 1 which can meet the various shapes of the knitting of a single cylinder double bed circular knitting machine while maintaining the high operating speed of the knitting machine. .

Figures 1 and 2, which darken the selection heel for clarity, illustrate an arrangement aimed at performing the knitting operation by rib stitches. By means of the arrangement of the illustrated form, it is possible to carry out a 1: 1 selection, i.e., to move one needle in one feed while knitting adjacent needles remain excluded from the knitting operation, 1 It is possible to perform a: 3 selection, i.e., to move one needle in one feed to knit while the next three needles remain excluded, and to perform a 1: 7 selection That is, one needle can be moved to knit in one feed while the next seven needles remain excluded, and it is possible to perform a 2: 2 selection, i.e., the next two needles It is possible to move two needles in a feed while knitting to remain excluded, and to perform a 2: 6 selection, i.e. one while the next six needles remain excluded. Two needles in the feed can be moved to knit. While the needle of the cylinder, which is located in the needle of the dial, which is excluded from the knitting operation in the feed under consideration, forms a plain stitch, the knitting needle's needle forms purl stitches, thus creating a classic rib knit. To produce.
