The specific embodiment
Sewing machines uses at least two forward line to generate stitching (stitch) in workpiece conventionally.Workpiece can be a slice fabric, and it is placed on needle plate, needle plate be positioned at the suture needle that is attached on shank below.Pinprick is worn with upper thread (top thread).Threading suture needle is by workpiece and pass through needle plate, thereby makes at least pinprick pass workpiece.When suture needle is upwards driven in the wrong direction from its extreme lower position, it has produced a circle upper thread.Mechanism below needle plate catches this circle upper thread, and is secured on the bottom line providing by line cylinder, thereby produces stitching.The mechanism that captures upper thread consists of shuttle and line cylinder sub-assembly conventionally.Line cylinder, the spool of bottom line, is positioned at shuttle.This shuttle (shuttle) rotates by the motor in Sewing machines.This shuttle is synchronously rotated in moving up and down of motor and suture needle.Shuttle comprises shuttle, and this shuttle has bill.Bill by planar coil at bottom line around and produce purl.Shuttle rotates with the motion of suture needle in time, so that bill captures the every circle upper thread that moves upward and produce along with suture needle.The rotation of shuttle is (timed) regularly, make bill with respect to the motion of suture needle in correct position, otherwise upper thread and bottom line may not form suitable stitching.
The timing of system (timing) is commonly referred to the timing (timing) of Sewing machines.Swing in the Sewing machines of horizontal suture needle swing mechanism of left position and location right having the suture needle of making, when suture needle is at it in each possible position time, the timing of Sewing machines may be undesirable.When Sewing machines " absonant ", also, when Sewing machines is regularly not the best, bill may be with respect to pinprick in optimum position.This can occur in when suture needle is during in different lateral attitude.This may cause ropy stitching, bouncing pilotage and broken string.Conventionally, when bill surpasses the suture needle of rising, the lowest part of bill should just in time be positioned at the top of pinprick.In thering is the Sewing machines of horizontal suture needle swing mechanism, when suture needle is during in its multiple position in may lateral attitude, bill with respect to pinprick only in optimum position.Other factors that relate to the current sewing situation of Sewing machines also may cause that Sewing machines is absonant.
Fig. 1 a-1f has described the sewing sub-assembly 100 of prior art.In sewing sub-assembly 100, suture needle 101 is in intermediate lateral position.In Fig. 1 c and 1d, suture needle 101 is in lateral attitude, the leftmost side.In Fig. 1 e and 1f, suture needle is in lateral attitude, the rightmost side.In all Fig. 1 a-1f, to work as by the generation coil that moves upward of suture needle 101, the moment that the bill 102 of shuttle 103 is about to gripping surface coil (not shown) is described Sewing machines.As shown in Fig. 1 a-1f, according to horizontal suture needle position, at bill 102, capture the moment of coils, bill 102 by the pinprick with respect to suture needle 101 104 in different upright positions.
In the sewing sub-assembly of prior art, if be regularly such, when suture needle 101 is during in left-most position, bill 102 is at the correct position with respect to pinprick 104, and when suture needle 101 is during in any other lateral attitude, the bill 102 of prior art sewing sub-assembly may become too low or too high with respect to pinprick 104.Therefore the variable timing system of prior art is not best, and bill is not accurately located all horizontal suture needle positions.This may cause ropy stitching, bouncing pilotage and broken string.
Each aspect of the present invention and each embodiment provide Sewing machines improved variable timing system, make to avoid the ropy stitching, bouncing pilotage and the broken string that by the timing differing from, are caused.
Disclosed variable timing system can guarantee bill with respect to pinprick in correct position, and no matter the lateral attitude of suture needle, can also regulate otherwise can make the Sewing machines absonant sewing condition that becomes.According to each side and each embodiment, improved variable timing system comprises having the shuttle of grabbing line bill.Variable timing system also comprises the first helical gear being arranged on shuttle, and is configured to synchronously rotate with the vertical motion of the shank with Sewing machines the lower shaft of shuttle.This variable timing system also comprises the second helical gear that is arranged on lower shaft and can engages with the first helical gear engagement.At least one in the first helical gear and the second helical gear be motion in the axial direction optionally.
Variable timing system can also comprise control appliance, and it is configured to process to represent the data of the current sewing state of Sewing machines, and the data that this equipment can respond processing optionally produce control signal.Variable timing system can also comprise driving force mechanism, and it is configured to reception control signal, and by axially-movable be delivered to can axially-movable helical gear.Driving force mechanism can axially move can axially-movable helical teeth take turns to a position in a plurality of selectable positions, to guarantee that bill is in correct position, described a plurality of selectable positions provide the scope that extends to the second end position from first end position.
According to second aspect, disclose for optionally regulating the method for timing of the variable timing system of Sewing machines.Variable timing system comprises having the shuttle of grabbing money bill, and is arranged on the first helical gear on shuttle.Variable timing system also comprises lower shaft, and this lower shaft is configured to synchronously rotate shuttle with the vertical motion of the shank of Sewing machines; With the second helical gear, it is arranged on lower shaft and can engages with the first helical gear engagement.At least one in the first helical gear and the second helical gear be motion in the axial direction optionally.The method comprises by control appliance processes the data that represent the current sewing state of Sewing machines.The method also comprise in response to the data selection of processing produce control signal, and in response to control signal, by axially-movable be delivered to can axially-movable helical gear, so that movement can axially-movable helical teeth take turns to a position in a plurality of selectable positions, to guarantee that bill is in correct position, described a plurality of selectable positions provide in the scope that extends to the second end position from first end position.
