Description

Warp loom

Technical field

The present invention relates to a kind of warp loom (Kettenwirkmaschine), it is included in the device framework that wherein is supported with spindle line (Hauptwellenstrang), also comprises drive motors and the function connector (Wirkverbindung) between drive motors and spindle line.

Background technology

The spindle line also can abbreviate " main shaft " as, and it is used as the main driver part of warp loom.The rotation of main shaft is expressed (Barre) by the push rod machine of being delivered to, and is used to produce definite machine and expresses motion.Function pin machine is expressed each formation to be lifted in the mesh process and descends.Localization machine is expressed (Legebarren) essential oscillating motion (Durchschwingbewegung) of carrying out by main shaft control.

In by warp loom known in putting into practice, drive motors is on so-called termination, location parts on the device framework end.These termination parts also have the function of supporting jacquard weave transmission device (Mustergetribe) except this task of holding motor, this jacquard weave transmission device is arranged on the drive motors usually.The spindle line is stretched being provided with the side plate that passes device framework on the end of drive motors.In the side plate of device framework, be supported with the spindle line, and seal towards side plate.This is essential, because device framework is filled with oil for lubricated bent axle.Drive motors acts on the outstanding end.

This structure is verified in the past to be reliable.

But especially in braiding (for example building industry textiles) technical field, more and more need the braided fabric of relative broad, need the warp loom of respective width for this reason, promptly warp loom need have bigger working width.It has been observed that now, along with the increase of working width has also obviously increased potential faults.

The utility model content

The objective of the invention is, in the bigger warp loom of working width, make potential faults keep less.

This purpose is achieved in the warp loom of above-mentioned form thus, and promptly the function connector is arranged between two ends of spindle line.

Problem in the bigger warp loom of working width is traced back to, and the rotation that is in operation of spindle line is if this drive line is driven from an end.This causes, and the disalignment that is arranged on the spindle line is moved no longer simultaneously to locational push rod, also makes thus to be expressed on its length no longer simultaneously and with same form by the machine of top rod driving to load, and this may cause problem.If now the function connector is arranged between two ends of spindle line, drive motors is also acted on the spindle line in the centre of spindle line, then obtain so-called two spindle line branches thus, they are significantly shorter than spindle line itself.Make rotation begin to distribute from the function connector in the axial direction thus towards two ends of spindle line.Correspondingly, make the maximum absolute rotation that produces keep littler, make thus to drive the push rod motion simultaneously to a great extent that the braiding toolroom machine is expressed, this also produces positive impact generally to the motion that the braiding toolroom machine is expressed.Make potential faults keep small thus.

Described function connector is preferably disposed in the axial zone line of spindle line.Make distribution of torque thus on two half practically identical spindle lines.In the ideal case, two half in addition just in time identical.But also can tolerate certain difference.Therefore the segmentation of spindle line on function connector one side can be positioned at 40 to 60% of spindle line length generally, and another branch then is supplemented to length 100% of spindle line.

Described device framework preferably has crankcase structure, is supported with the spindle line therein, and wherein crankcase structure has discontinuities, and the spindle line passes it and guides and be provided with therein the function connector.Described device framework have at least one, but common a plurality of crankcases, they are filled with oil, are used for the bearing of lubricated spindle line.Because discontinuities, crankcase structure has two sidewalls now, and the spindle line passes them and guides.In these two sidewalls, also need there be seal certainly.But this is no problem.Between these two sidewalls (promptly in discontinuities), can touch the bent axle drive line from the outside, the function connector can here work thus.

Described function connector preferably has the transfer element that encloses card spindle line.

Thus, the function connector is gone into this danger in the spindle line with shuttle belt, and is littler when ratio such as gear drive.

Described transfer element preferably is made of cingulum.Cingulum is made of reinforcing elastomeric material, and it has the effect of buffering vibration in certain limit.

Described drive motors preferably is bearing on the carriage (Konsole) that separates with equipment rack.The vibration that drive motors is produced is not directly delivered on the equipment rack.Aspect vibration, can between drive motors and equipment rack, realize certain decoupling connection.

Described drive motors preferably is connected with equipment rack by the support unit of at least one buffering vibration.This support unit guarantees that drive motors has relative accurate localization each other with equipment rack.Being in operation also keeps this position, promptly can not produce skew.But because support unit has cushioned the vibration that is produced by drive motors, so these vibrations are not delivered on the equipment rack.This hidden danger that thus vibration is brought in the spindle line keeps small.

Described spindle line preferably has a plurality of shaft parts, and wherein two shaft parts interconnect by clutch respectively, and wherein the clutch quantity along the spindle line is identical in the both sides of function connector.Use a plurality of shaft parts to make the production of spindle line easier, and make the assembling of spindle line in equipment rack easier.If all be provided with the shaft part of practically identical quantity in each side of function connector, then obtain drive characteristic near symmetry, the result is, this dangerously keeps small in the excessive rotation of function connector to the direction of end to make the spindle line.

Description of drawings

By means of preferred embodiment the present invention has been described in conjunction with the accompanying drawings below.In the accompanying drawing:

Fig. 1 illustrates the partial top view of warp loom with the form of extremely simplifying;

Fig. 2 illustrates the cross-sectional view according to the II-II of Fig. 1.

The specific embodiment

Fig. 1 shows the partial view of warp loom with the form of extremely simplifying, i.e. equipment rack 2 (being also referred to as device framework), and rotatably mounted therein have a spindle line 3.This spindle line is made up of a plurality of shaft part 4-9, wherein two

adjacent shaft parts

4,5; 5,6; 7,8; 8,9 interconnect by clutch 10-13 respectively.

Described equipment rack 2 has a plurality of crankcase 14-19.Push rod is connected with each shaft part 4-9, and wherein push rod finally forms drive unit, is used for same unshowned braiding toolroom machine and expresses.

Crankcase 14-19 forms crankcase structure together.This crankcase structure interrupts between crankcase 16,17, that is, it has discontinuities 20, and this discontinuities 20 is by two sidewalls, 21,22 restrictions of device framework 2.Shaft

part

6,7

passes sidewall

21,22 hermetically and guides, and makes crankcase 14-19 still can be full of oil (or other lubricant) thus.

Drive motors 23 is bearing on the carriage 24, and this carriage separates with equipment rack 2.Carriage 24 is the same with equipment rack to be placed on the ground, for example on the ground in workshop.Carriage 24 is bearing on the equipment rack 2 by a plurality of

support units

25,26,27, obtains also obtaining thus between carriage 24 and the equipment rack 2 exact position between drive motors 3 and the spindle line 3 thus.Support unit 25-27 has the characteristic of buffering vibration, i.e. the vibration of drive motors 3 can or only not be delivered on the equipment rack 2 with very small degree.

Drive motors 23 has the function connector 28 with spindle line 3.This function connector 28 is used to make the torque or the driving torque that are produced by drive motors 23 to be delivered to spindle line 3.

For this reason, function connector 28 has the transfer element 29 of cingulum form, and it is guided by the toothed belt wheel 31 on toothed belt wheel on the drive motors 23 30 and the spindle line 3.Transfer element 29 also encloses card spindle line 3 in a circumferential direction.

Described function connector 28 is arranged on the centre of spindle line 3, promptly at the axial zone line of spindle line 3.But needn't be accurate in the middle of this.Can in 40: 60 to 60: 40 scope of spindle line total length, select in the length on function connector one side.But on the both sides of function connector, the quantity of clutch 10-13 is identical, and shaft part 4-6 thus, and the quantity of 7-9 also is identical.

If drive motors 23 makes spindle line 3 place rotation and drives thus now, then spindle line 3 itself drives above-mentioned push rod, and push rod applies load torque to spindle line 3.Along with the increase of the distance of the driving torque that imports, this load torque can cause the rotation of spindle line 3 itself.This rotation now is evenly distributed in the both sides of function connector 28, and is the same big under the situation on making rotation (in order to simplify expression) thus and acting on spindle line one end at drive motors.Push rod and connected braiding toolroom machine are expressed on its working width load equably, can make potential faults keep small thus.

By using supporting 25-27 also to guarantee to have only small vibration to be delivered on the spindle line 3 from drive motors 23, this has further reduced potential faults.
