Description

Изобретение относится к трикотаж³' ному машиностроению и предназначено для использования на кругловяэальных купонных машинах, вырабатывающих полурегулярные изделия·.The invention relates to knitwear ³ 'mechanical engineering and is intended for use on circular veal coupon machines producing semi-regular products

Известен игольный замок, предусматривающий перемещение подъемного клина из выключенного в рабочее положение под острым углом к отбойной плоскости. Этот замок имеет корпус, в котором на оси вращения закреплен рычаг, кинематически связанный с механизмом управления и несущий подъемный клин [д!·Known needle lock, providing for the movement of the lifting wedge from off to working position at an acute angle to the bump plane. This lock has a housing in which a lever kinematically connected to the control mechanism and carrying a lifting wedge is fixed on the axis of rotation [d! ·

Существенным недостатком этой конструкции является то, что во время переключения подъемного клина не все иглы, взаимодействующие d клином, достигают уровня заключения. Иглы, которые не достигают заключения, образуют прессовые петли, что не соответствует программе вязания и снижает качество вырабатываемого трикотажа. Для того, чтобы уменьшить количество самопроизвольно получающихся прессовых петель, сокращают время переключения подъемного клина за счет перемещения клина со значительной скоростью. Это приводит к тому, что при встрече подъемного клина с пят20 ками игл имеет место удар, который вызывает повышенные нагрузки в паре клин - игла, способствует повышенному износу клиньев и игл и снижает надежность работы машины.A significant drawback of this design is that during the switching of the lifting wedge, not all needles interacting with the d wedge reach the level of confinement. Needles that do not reach a conclusion form press loops, which does not correspond to the knitting program and reduces the quality of the produced knitwear. In order to reduce the number of press loops spontaneously obtained, the switching time of the lifting wedge is reduced by moving the wedge at a considerable speed. This leads to the fact that when a lifting wedge meets five needles of needles, a shock occurs that causes increased loads in the pair of wedges - needles, contributes to increased wear of wedges and needles and reduces the reliability of the machine.

Целью изобретения является повышение качества вырабатываемого трикотажа за счет уменьшения количества прессовых петель, самопроизвольно получающихся при переключении подъемного клина, а также повышение надежности работы машины.The aim of the invention is to improve the quality of the produced knitwear by reducing the number of press loops spontaneously obtained when switching the lifting wedge, as well as improving the reliability of the machine.

Указанная цель достигается тем, что в игольном замке, содержащем связанный с механизмом управления подъемный клин, на оси,закрепленой на корпусе игольного замка, смонтирован переключаемый по командам от механизма управления рычаг, снабженный пальцем, размещенным в пазу корпуса и входящим.в отверстие подъемного клинаj на подъемном клине или на корпусе жестко закреплен штифт, находящийся в контакте с прямолинейным направляющим пазом.This goal is achieved by the fact that in the needle lock containing a lifting wedge connected to the control mechanism, on the axis fixed to the needle lock case, a lever is switched that is switched by commands from the control mechanism and equipped with a finger placed in the groove of the housing and entering the opening of the lifting wedgej a pin in contact with the straight guide groove is rigidly fixed on the lifting wedge or on the housing.

Предусмотрены два варианта выполнения штифта и направляющего паза: в первом варианте штифт закреплен на корпусе, а^паз выполнен в подъемном клине параллельным егр рабочей кромке} во втором варианте штифт закреплен на подъемном клине, а паз выполнен на корпусе параллельным от-, войной плоскости.There are two options for the implementation of the pin and the guide groove: in the first embodiment, the pin is fixed to the housing, and the groove is made in the lifting wedge parallel to the edge of the working edge} in the second version, the pin is fixed on the lifting wedge, and the groove is made on the case parallel to the war plane.

Переключаемый рычаг перпендикуляр рен рабочей кромке подъемного клина, находящегося в положении заключения.The switchable lever is perpendicular to the working edge of the lifting wedge in the closing position.

B in FIG. 2.

На-корпусе 1 (Фиг. If игольного замка цилиндра кругловязальной купонной машины установлен подъемный клин 2, кулирный клин 3 и направляющие клинья 4-7. Клин'2 может занимать одно из следующих трех положений: положение заключения (показано сплошной линией)положение прессования (не показано); выключение положения (показано пунктиром).On the casing 1 (Fig. If the needle lock of the cylinder of the circular knitting coupon machine, a lifting wedge 2, a cooking wedge 3 and guide wedges 4-7 are installed. The wedge'2 can occupy one of the following three positions: position of the conclusion (shown by the solid line) pressing position ( not shown); turn off the position (indicated by a dotted line).

Подъемный клин 2 имеет рабочую кромку 8 И оснащен пазом 9 и отверстием 10 (фиг. 2), в котором помещен палец 11 рычага 12, проходящийчерез паз 13 корпуса 1. Рычаг 12 установлен с возможностью поворота на оси 14, жестко закрепленной на корпусе 1, и . связан яри помощи тяги 15 (фиг. 2 и 5) с механизмом управления, в пазу 9 клина 2 размещен штифт 16, жестко закреплённый на корпусе 1 (фиг. 1), причем паз 9 параллелен рабочей кромке 8 клина 2.The lifting wedge 2 has a working edge 8 And is equipped with a groove 9 and a hole 10 (Fig. 2), in which a finger 11 of the lever 12 is inserted, passing through the groove 13 of the housing 1. The lever 12 is mounted to rotate on an axis 14, rigidly mounted on the housing 1, and. the yari of the traction 15 (Fig. 2 and 5) is connected to the control mechanism, a pin 16 is placed in the groove 9 of the wedge 2, rigidly fixed to the housing 1 (Fig. 1), and the groove 9 is parallel to the working edge 8 of the wedge 2.

Предусмотрен вариант выполнения направляющего паза в корпусе игольного замка (фиг. 4).„в этом случае паз 17 параллелен отбойной плоскости, а штифт 18 жестко закреплен на подъемном клине 19. Управление клином 19 происходит при помощи рычага 20, установленного с возможностью поворота относительно оси 21, закрепленной на корпусе’. Перемещение игл по необходимой для осуществления процесса петлеобразования траектории происходит за счет взаимодействия пяток 22 игл (фиг. 1) с клиньями.An embodiment of the guide groove in the needle lock housing is provided (Fig. 4). “In this case, the groove 17 is parallel to the baffle plane, and the pin 18 is rigidly fixed to the lifting wedge 19. The wedge 19 is controlled by a lever 20 mounted for rotation about an axis 21 mounted on the housing. ' The movement of the needles along the trajectory necessary for the process of loop formation occurs due to the interaction of the heels of 22 needles (Fig. 1) with wedges.

Предлагаемое устройство работает . следующим образом.The proposed device works. in the following way.

В том случае, когда клин 2 занимает положение заключения пятки 22 игл, взаимодействуя с рабочей кромкой 8, поднимаются на заключение. Затем, попадая под действие направляющего клина 4 и кулирного клина 3, иглы опускаются, образуя петли. В . дальнейшем под действием клапанооткрывающей горки клина 6 происходит открытие язычков игл и иглы переходят в следующий игольный замок. В случае, когда клин 3 занимает выIn the case when the wedge 2 occupies the position of the conclusion of the heel 22 needles, interacting with the working edge 8, rise to the conclusion. Then, falling under the action of the guide wedge 4 and the cooking wedge 3, the needles lower, forming a loop. IN . Further, under the action of the valve-opening slide of the wedge 6, the tongues of the needles open and the needles pass into the next needle lock. In case wedge 3 takes you

SO ключенное положение (показано пунктиром на фиг. 1), иглы не поднимаются и проходят через игольный замок, не образуя петель.SO locked position (shown by the dotted line in Fig. 1), the needles do not rise and pass through the needle lock without forming loops.

Переключение подъемного клина 2 происходит под действием тяги 15, получающей перемещение от механизма управления. Тяга 15 поворачивает рычаг 12 вокруг оси 14, при этом п5лец 11, поворачиваясь в пазу 13 корпуса 1, воздействует на клин 2. Паз 9 клина 2 перемещается относительно неподвижно установленного на корпусе штифта 16. Таким образом, клин 2 в процессе переключения совершает сложное движение, которое складывается из поворота вокруг пальца 11, качающегося вокруг оси 14 рычага 12, и перемещения паза 9 относительно неподвижного штифта 16. Конструкция, изображенная нафиг. 4 переключается аналогично описанной.Switching the lifting wedge 2 occurs under the action of the rod 15, which receives movement from the control mechanism. The rod 15 rotates the lever 12 around the axis 14, while the pivot 11, turning into the groove 13 of the housing 1, acts on the wedge 2. The groove 9 of the wedge 2 moves relative to the pin 16 fixed on the housing. Thus, the wedge 2 makes a complex movement , which consists of turning around a finger 11, swinging around the axis 14 of the lever 12, and moving the groove 9 relative to the fixed pin 16. The design shown in FIG. 4 switches as described.

предлагаемое изобретение позволяет повысить качество ’вырабатываемого на машине трикотажа за счет ликвидации возможности появления не предусмотренных программой вязания прессовых петель, в описанной конструкции перемещение подъемного клина •в процессе переключения происходит по ходу движения игл с уменьшением относительной скорости игл и включаемого клина, при этом траектория Движения включаемого подъемного клина такова, что все иглы гарантированно поднимаются в положение заключения. Предлагаемый игольный замок дает возможность производить переключение подъемного клина без снижения скорости машины, что повышает ее производительность. Кроме того, уменьшаются динамические нагрузки, возникающие между клином и пятками игл. Это уменьшает износ игл и клиньев и повышает надежность работы машины. Снижение нагрузок в системе переключения клина достигается также тем, что равнодействующая от сил давления пяток игл на рабочую кромку подъемного клина, находящегося в положении заключения, направлена вдоль рычага 12 (фиг. 3) или рычага 20 I фиг. 4) вследствие перпендикулярности рычага рабочей кромке клина. В результате этого рычаг находится в мертвом положении, что разгружает систему переключения клина, занимающего положение заключения.the present invention improves the quality of the knitwear produced by the machine by eliminating the possibility of the appearance of press loops not provided for by the knitting program, in the described construction the movement of the lifting wedge • during switching occurs along the direction of movement of the needles with a decrease in the relative speed of the needles and the wedge being turned on, while the trajectory of movement The included wedge is such that all needles are guaranteed to rise to the locked position. The proposed needle lock makes it possible to switch the lifting wedge without reducing the speed of the machine, which increases its productivity. In addition, the dynamic loads that occur between the wedge and the heels of the needles are reduced. This reduces wear on needles and wedges and improves machine reliability. The reduction of loads in the wedge switching system is also achieved by the fact that the resultant from the pressure forces of the heels of the needles on the working edge of the lifting wedge in the closing position is directed along the lever 12 (Fig. 3) or the lever 20 I of FIG. 4) due to the perpendicularity of the lever to the working edge of the wedge. As a result of this, the lever is in the dead position, which unloads the switching system of the wedge, which occupies the position of the conclusion.

In the groove 9 of the wedge 2, there is a spindle 16 rigidly attached to the body -1 (Fig. 1), and the groove 9 is parallel to the working edge 8 of the wedge 2. A variant of the guiding pgaz is provided in the case of the needle lock (Fig. 4). in the case, the groove 17 is parallel to the break-away plane, and the pin 18 is rigidly fixed on the lifting wedge 19. The wedge 19 is controlled by means of a lever 20 that can be rotated about an axis 21 fixed to the housing. The movement of the needles to the needles for the implementation of the process of looping the trajectory occurs due to the interaction of a stream of 22 needles (Fig. 1) with wedges. The proposed device works as follows. In the case when the wedge 2 takes the position of the conclusion of the needle 22 of the needles, interacting with the working edge 8, they rise to the conclusion. Then, under the action of the guiding wedge 4 and the kulir wedge 3, the needles are lowered, forming a loop. AT . Further, under the action of the valve-opening slide of the wedge b, the needles open and the needles open into the next needle lock. When the wedge 3 is in the off position (shown by the dotted line in Fig. 1), the needles do not lift and pass through the needle lock without forming loops . The switching of the lifting wedge 2 occurs under the action of the rod 15, which receives movement from the control mechanism.
