Description

Detachable and/or the collection group of opening the fabric of type knitting circular knitting machine for knitwear

Technical field

The present invention relates to the knitting circular knitting machine for knitwear, described knitting circular knitting machine is considered to " opening " type and has the pedestal (base-frame) of size reduction.In more detail, the present invention relates to for opening the pedestal of type knitting circular knitting machine.Further, the present invention relates to open type knitting circular knitting machine, the type knitting circular knitting machine of opening has the detachable and/or collection group (take-down and/or collecting group) of fabric, and wherein said fabric is by this production of machinery.The invention further relates to specify and be installed in the detachable and/or collection group of opening in type knitting circular knitting machine.In addition the present invention relates to for opening the tension roller (tensioning roller) of the detachable and/or collection group of type knitting circular knitting machine.

The present invention relates to justify latitude machine technology field for the weaving of textiles, for the weaving of textiles, justify latitude machine and belong to the type that this area is known as " opening ".This type comprise be equipped with at least one needle bearing element (needle-bearing organ), for controlling the knitting circular knitting machine of the detachable and collection group of the cam device of motion of pin and (especially), the knitting circular knitting function collection of wherein said detachable and collection group is by the woven (especially by being wound on the woven of producing on roller) of production of machinery.By cutting open and outwards open (open out) tubing (as a rule, machine is continuously produced tubing), can obtain from needle bearing element and by the woven detachable and collection of collection group, or as an alternative, woven can directly be produced by " be opened ground ", as the fabric (having definite width) of single pantostrat.In other words, by the longitudinal formation direction being parallel to the woven of being produced or outwards opened from machine, cut open continuously that (this is called as term and " opens ", for the type of recognition machine), detachable and collection group is collected woven (by being wound on roller) and tubing (the continuous band-shaped structure that woven has certain width also can obtain woven by outwards opening tubular structure) that non-cylindrical becomes.

The type knitting machine of opening can comprise the group of only collecting sometimes, and this group lacks detachable function.This is real for the machine that for example those needle-bar places at a plurality of pins directly carry out dismounting; In this case, the fabric of being produced by needle bearing element drops in collection group, described collection group conventionally by winder (winder) by fabric wrapping on roller.In a word, the type machine of opening may be defined as knitting circular knitting machine, and in knitting circular knitting machine, the fabric of production " is opened ground ", and (with form of single sheet) collected and be wound onto on collection roller.

In all fields, knitting circular knitting machine of the present invention can be single needle bed type (having single syringe) or two-needle bar type (having a syringe and a dials).

Claim of the present invention (referring to " opening type " knitting machine) is determined the knitting machine (these features are clear and have a clear meaning and determine in reference to field and limit this type) of the machine with above-described opening characteristics clearly, and becomes apparent for the expert of this area.Therefore, should correctly explain the term using in claim according to the data with reference technique domain-specific.Especially, the feature of opening type machine according to the present invention is understood to clear and definite technical characterictic in existing many type machine, described clear and definite technical characterictic is construed as limiting and should be interpreted as an only example of knitting machine, also comprises other technical characterictic of setting forth in claim on knitting machine.

Background technology

In the knitting machine field for knitwear, " opening " type knitting circular knitting machine is known.These machines have special pedestal, pedestal forms the load-carrying members of machine and for supporting and holding all machine parts, especially knitting head (knitting head) (control member that comprises needle bearing element, a plurality of pin and pin) and detachably and collection group.Pedestal can also rest machine the job site of appointment securely.

The type machine of opening has needle bearing element (being syringe or dials) conventionally, and the diameter of needle bearing element is approximately 30-40 inch, but has other example that diameter is less (for example 24 inches).The knitting machine that surpasses 40 inch diameters has oversized dimensions, is difficult to realize and shift.

As described above, the type knitting circular knitting machine of opening is produced tubing conventionally, and tubing is opened by means of longitudinal cutting of being carried out by cutter, be then opened and outwards launched so that by individual layer be wound on and collect on roller.As a result, the lateral dimension (below cylinder) that is collected in the type of the opening fabric on roller doubles with respect to the due diameter of " pressing " uncut tubular products (be closed to be formed on the two-layer fabrics of both sides place's combination).Thereby fabric is opened and causes the size of cylinder below (region that holds detachable and/or collection group) machine significantly to increase.This region must not have can hinder detachable and/or the structure of collection group and the structural detail of motion, and detachable and/or collection group forms the size needing to collect the type of the opening fabric that is unfolded its whole width.Obtain thus the following fact: the pedestal of the type of the opening knitting machine of known type has significant size.

The type of the opening knitting circular knitting machine that belongs to prior art all has three leg pedestals, and three leg pedestals are arranged in circumferentially around detachable and/or collection group and support preferably the support ring that knitting head and syringe are installed on it.These three legs normally equal angular (being that they present hexagonal angle degree each other).Conventionally, three legs wherein one form main leg, main leg is larger and for holding the control member of machine with respect to other two " side " legs.Consider the element in the running of the very heavy weight of structure, large size and existence, this pedestal structure can support whole machine securely.Known structure is designed to prevent machine overturning and limits seismism.

Three leg pedestal structures of known type have a series of shortcomings.The first, be clear that, three legs that are circular layout cause machine in width and the upper large size of length (considering two dimensional directions that knitting machine is perpendicular to one another in plane).Conventionally, the length of machine is defined as the axis along the collection roller of fabric through main leg, and the wide maximum that is defined as two side leg extends laterally.Generally, the size of machine can be diagrammatically expressed as a rectangle, and this rectangle has length mentioned above and wide, and the size of machine is the function of dimension and the layout of three legs; The structure of known pedestal has large length and width size.

The large weight of the pedestal of existing machine is being opened the difficult problem that type knitting machine field is a highly significant because for realize the largest contours of machine be limited to easily with moderate cost, realize and by means of standard means of transport (and non-special transportation), to make machine be transportable.In more detail, for freight transportation, there is strict standard, do not allow to surpass long and wide concrete size.The size of these standards and means of transport (for example lorry, train and truck) and for Size dependence connection, the especially width of these containers and instrument (being conventionally no more than 230-240cm) of the container of freight transportation.

Therefore, in the machine of known type that has three leg pedestals, the requirement that does not exceed these restrictions is caught to implement this class machine and becomes difficult, this is because the width of the fabric that is collected is corresponding to the size of detachable and/or collection group far away surpassing for holding the external dimensions of the pedestal of described detachable and/or collection group even also, and these machines can be produced the width having over specific limited.This is extremely disadvantageous, because what want is can produce also " open ground " to collect the fabric with even larger width.

Another shortcoming of known machine (due to three leg structures of pedestal) is not accessible knitting head and needle bearing element.This causes the reducing of the productivity of machine, because this structure makes operator be difficult to intervene, for example, in the damaged situation of online or pin, intervenes.Similarly, due to the existence of the leg of pedestal, the installation and maintenance of machine element not only the time long but also very difficult.

In order to overcome the shortcoming being caused by three leg pedestals, applicant has realized and opened type knitting circular knitting machine in the past, and this is opened type knitting circular knitting machine and has the three leg pedestals that are distributed with non-constant angle (not being 120 °) therebetween.In this solution, every leg in two side leg and main leg (longitudinal axis along this machine is arranged) all form the angle (for example 135 °) that is greater than 120 °, and between two side leg, angle is less than 120 ° (for example 90 °).In other words, this just looks like that two side leg are rotated backward, thereby reduces angle folded between them.In this manner, likely the width of machine is reduced to limited value and increases length simultaneously.Because transportation clearance is mainly limited in width, to length, be tolerant, so this is favourable, this is because the increase of length itself does not form problem.

Another known solution of attempting solving three leg dimensional problem has been described in patent EP1253230.This patent has been set forth three leg pedestals, wherein has a fixing main leg (longitudinal axis along machine is arranged) and with respect to two of longitudinal axis symmetrical side leg, and this three legs pedestal can convert between transportation configuration and active configuration.Side leg can change their radially extension (with respect to the central axial line of machine), so as in transportation configuration near central branches pushing out ring (thereby thering is the wide of smaller szie) and in active configuration widely away from central branches pushing out ring.By means of a pair of horizon bar (rod) for every side leg (or a pair of " extensible thing "), can change radially and extend, when described side leg is during in active configuration, the bottom that this is connected to the top and bottom of every leg supporting leg and is connected to pedestal horizon bar (or this is to " extensible thing "); When described side leg is when transportation configures, this is removed (by side leg being directly installed to the bottom of support ring and pedestal) to horizon bar.Note, in active configuration, (obtaining by means of extensible thing) radial distance of the side leg of central branches pushing out ring can provide a free space below cylinder, and this free space can hold and move detachable and collection group; Machine can correctly operate in this way.On the contrary, transportation configuration only can be for following object: in fact side walls is installed in from the position (to reduce wide size and be conducive to transportation) close to cylinder and in occupation of the space that is specified for the rotation of detachable and gathering element.

Yet, applicant finds can not overcome these shortcomings completely and can improve in many ways for opening the modified pedestal (that is, leg is arranged to non-constant angle or has the dismountable leg as described in patent No. EP1253230) of type knitting machine.Especially, known solution only can partly limit the width dimensions of opening type knitting machine; This means and still have relevant transportation problem.Further, the problem being associated with not accessible knitting head and needle bearing element (for the basic principle of intervening fast on machine) is only eased but not solves.

Further, the solution that (pedestal of particularly describing in patent No. EP1253230) provides has the structure that is difficult to realization, and/or the machine for transporting and moving is configured and needs complicated operation.

The type knitting circular knitting machine of opening generally includes a device (known in the art is detachable and collection group), and this device collects in individual layer mode the fabric of being produced by knitting machine on collecting layer.Detachable and collection group can further be used for " expansion " from the fabric of needle bearing element, guarantees the decline of described fabric when fabric is produced in the position of pin; In some machines, the dismounting of fabric just in time occurs in the position near needle bearing element, and described group only for collecting fabric (being tightened up).

In producing the type of the opening machine of tubing (not producing by the fabric of direct " outwards opening "), detachable and/or collection group comprises cutter elements, cutter elements can longitudinally cut open the tubing of being produced by needle bearing element according to the mode that fabric " is opened ", therefore can be by fabric single laminate roll around collecting on roller.

Detachable and collection group can comprise other element, for example: the pressing member of tubing, for open the fabric being cut open outside opening members, for make fabric on its path towards the lockout member of collecting the controlled traction roller advancing of roller (collecting roller) (traction roller), transmission device (actuator) and each element and moving.

Detachable and collection group is installed to machine conventionally and below needle bearing element (in being assigned to specially the collection space of this group), and can rotate securely along with needle bearing element, to follow the production of fabric and collect fabric with the mode of roll (roll) or the mode of superimposed fold layer.In patent document EP0456576, EP0696658 and WO00/50678, set forth for opening the example of the detachable and collection group of type knitting machine.In more detail, detachable and collection group has framework, organizes all elements described in described frame supported and is disposed in the below of knitting head in machine.Whole framework is along with needle bearing element rotates securely, and for example, further rests in going to the bottom of machine by supporting member (comprising bearing), and supporting member bears weight and makes rotation become possibility simultaneously; In order to make whole framework rotation, at the supporting member of going to the bottom, can be activated by (for example, by motor).

Applicant finds that the type of the opening knitting machine (the especially detachable and collection group of these machines) of known type has shortcoming, but can improve in many ways.The first, known detachable group has shown weight and large size.Further, especially, because needs support the whole load of the detachable and collection group in rotation status and need to make synchronized movement with respect to needle bearing element, by detachable group, be inserted into connection and the moving link that needs complexity and costliness in machine.

When considering to open type knitting machine, these problems can increase, and the type knitting machine of opening has large-sized needle bearing element conventionally, and large-sized needle bearing element needs equally very large complicated detachable and collection group.

Detachable and the collection group of known type has at least one spreader roller (stretcher roller) or tension roller conventionally in inside, at least one spreader roller or tension roller are being collected the upstream interception fabric of roller, and be configured to open gradually fabric at the width of fabric the degree arrival collection roller that makes fabric open with its maximum and launch on its whole width.In patent document EP0534917 and WO00/50678, set forth the example of the spreader roller with this object: roller has two parts that have groove, these two have the part of groove extending spirally towards the contrary direction in roller two ends from central authorities.

Yet applicant finds that known spreader roller has some restrictions and shortcoming.

Further, the spreader roller of known type can not effectively make fabric integrity ground outwards launch before fabric arrives collection roller; This causes the fabric of piling up on collection roller to have fold, folding line and/or less desirable overlapping, maybe needs to adjust the operation bidirectional of collecting the fabric on roller; Wherein this accumulation can damage fabric and reduce the quality of fabric, makes follow-up complete or packaging operation or the action on fabric become complicated.

Further, the spreader roller of known type can not make material object and the size of the expansion carried out on fabric be modified; Can not distinguish the expansion degree being set up towards roller end in the different piece of the fabric through spreader roller.

And the feature of the spreader roller of known type is that complex structure and manufacture and maintenance cost are high.

Further, because known spreader roller has limited the efficiency that launch the side of fabric, so they have affected the performance of whole detachable and collection group; This need to use a plurality of spreader rollers or large scale spreader roller conventionally, and result increases complexity and/or size and/or the cost of realizing detachable and collection group.

The Efficiency Decreasing that causes whole size and collection group to launch fabric peripheral edges to the restriction of the spreader roller performance of known type, external margin is easy to roll self or reeled self at longitudinal direction, on every limit, forms the volume as a cigarette shaped.

Applicant also finds, in known detachable and collection group, from needle bearing element to collecting roller and a plurality of elements fabric cooperation (being outside opening members, spreader roller, tension roller and traction roller) according to not being that best mode is arranged mutually, (especially on the volume at fabric side edge) generation on fabric is not lined up and/or folding line, and cause inhomogeneous coiling on collection roller.
