Description

Description: TECHNICAL FIELD The present invention relates to a guide bar drive control device provided with a selective overlap mechanism in a guide bar drive control device in a warp knitting machine, particularly in a device using a gauge piece.

(Background technology)

The drive control device for the guide bar in the warp knitting machine of Japanese Patent Publication No. 61-23201 proposed by the applicant of the present invention is a yarn guide reed by setting the total amount of displacement by a so-called summing mechanism using a gauge piece. In the so-called SG reed drive device of the type that converts to an underlap amount, a cam mechanism for displacing a fulcrum shaft of a shog lever connected to a cam member connected to a summing mechanism to cause an overlap operation is provided. Things.

In this control device, usually, the overlap motion is executed every course by continuously rotating the cam. Although not adopted at present, as described in the text, the overlap can be selected by selecting the cam driving or non-driving course by mechanical or electrical means.

However, in the above-described device, it is necessary to provide an independent drive mechanism for each of a large number of parallel reeds, that is, for every 70 or more camshafts for more than 70 reeds at present. As a result, the implementation has not been achieved in terms of space and complexity of the mechanism.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, the present invention provides a simple mechanism using a gauge piece that selectively acts on the movement of a transmission rod of a summing mechanism that sets the amount of displacement of a guide bar and a pressing member that simultaneously performs a pressing operation. So that the pressing drive force can be collectively and selectively applied to the transmission rods corresponding to all the guide bars,
It is an object of the present invention to provide a guide bar drive control device of a warp knitting machine capable of simplifying the device, making it compact, and saving space.

[Disclosure of the Invention]

A guide bar drive control device according to the present invention is a warp knitting machine provided with a summing mechanism for setting a displacement amount of a guide bar, the displacement being possible in a moving direction of a transmission rod in the summing mechanism and engaging with a fixed portion. A floating member that regulates the displacement of the transmission rod, a gauge piece that selectively contacts one end surface of the floating member by a selection unit, and a pressing member that presses the floating member via the contacted gauge piece. By operating the pressing member by driving means to press the transmission rod via the floating member or to release the pressing on the transmission rod via the floating member, an overlap displacement is generated in the transmission rod. At the same time, the overlap displacement can be selected by the gauge piece and the action / inactivity.

In the guide bar drive control device configured as described above,
Underlap of the guide bar is performed by the displacement amount set by the summing mechanism. Then, by selecting the gauge pieces of only the guide bars that need to be overlapped by the instruction of the selection means for a large number of guide bars, and by bringing them into an operating state in which they come into contact with the floating member, they are simultaneously driven by the drive means. The pressing force of the pressing member is applied only to the location of the selected gauge piece to press the transmission rod of the summing mechanism via the floating member with which the gauge piece abuts, or the transmission via the floating member. Releasing the pressure on the rods will provide the necessary overlap displacement for these transmission rods.

For guide bars that do not require overlap, the gauge piece is not selected and is kept in an inactive state.
The pressing force of the pressing member by the driving means is not transmitted to the floating member and the transmission rod, and therefore, no overlap displacement is given.

Therefore, various patterns can be knitted by the combination of the setting of the displacement of the summing mechanism and the operation and non-operation of the gauge piece.

Therefore, the amount of displacement set by the multiple gauge pieces 8 and 9 is converted into the amount of underlap of the guide bar 2 via the transmission rods 6 and 7 and the shog lever 4 and applied.

Reference numeral 21 denotes the outer side of the sliding motion track 17A in the summing mechanism 1A, that is, on the extension of the transmission rod 6 on the opposite side to the cam member 5, in the moving direction of the transmission rod 6 in opposition to the transmission rod 6. It is a floating member provided so as to be capable of sliding displacement. Reference numeral 22 denotes the outer side of the sliding track 17B in the summing mechanism 1B, that is, on the extension of the transmitting rod 7 on the side opposite to the cam member 5, slides in the moving direction with the transmitting rod 7 in opposition to the transmitting rod 7. It is a floating member provided so as to be displaceable. These floating members 21 and 22
May be provided in the sliding tracks 17A and 17B so as to be slidable in the same direction as described above.

Reference numeral 23 denotes a fixing portion at which at least a part of the floating member 21 contacts and engages, and is fixed to the machine frame of the summing mechanism 1. Numeral 24 denotes a fixing part with which at least a part of the floating member 22 contacts and engages, and like the fixing part 23, is fixed to the machine frame. Floating member 2

Reference numerals 25 and 26 denote gauge pieces, so that they can selectively contact one side of the floating members 21 and 22 of the summing mechanisms 1A and 1B, that is, the side opposite to the side facing the transmission rods 6 and 7, for example. As shown in the figure, the jacquard head is suspended vertically from a jacquard head 10 as a selective means, and the step size is set in accordance with the gauge of the warp knitting machine.

27, 28 are pressing members as pressing members,

The slide track 17B is slidably provided on the extension of the slide track 17B so as to be able to freely contact with and separate from the slide track 26, that is, to be able to press freely.

The pressing body 27 is a bell crank 31 supported on a fixed shaft 29.
And a displacement generated by a cam 32 rotating in synchronization with a drive main shaft of the knitting machine is transmitted to the bell crank 31 via a rod 34 from a cam lever 33. The pressing body 28 is connected to a bell crank 36 supported on a fixed shaft 35 via a connecting rod 37, and the bell crank 36 has a displacement generated by a cam 38 that rotates in synchronization with the main shaft. The power is transmitted from the cam lever 39 via the rod 40.

The above is the schematic configuration of the apparatus according to one embodiment of the present invention.
Next, an operation state for specifically causing the overlap displacement will be described in detail with reference to FIGS.

FIGS. 2 and 3 show an operation state when an overlap displacement (a displacement from right to left in the drawing) occurs in the pushing direction of the guide bar 2 (the direction pushed by the sig lever 4). The state on the side 7 is acting on the summing mechanism 1B (not shown). Here, as shown in FIG. 2, the gauge piece 25 on the side of the summing mechanism 1A falls, and the pressing body 27 moves in the direction of the arrow by the action of the cam 32, and at the same time, the necessary amount of the multiple gauge piece 8 for underlap is used. And the transmission rod 6 acts in the direction of the arrow to perform an underlap operation. In this case, the floating member 21 is pushed by the transmission rod 6 and moves rightward in the drawing, and comes into contact with and engages with the fixing portion 23, whereby the transmission rod 6 is moved.
Is determined.

Then, the pressing body 27 moves in the direction of the arrow as shown in FIG. 3, and pushes the floating member 21 and pushes the transmission rod 6 while the gauge piece 25 is interposed between the pressing member 27 and the floating member 21. Then, the sig lever 4 is rotated to the left in the drawing to generate an overlap displacement, and the displacement is transmitted to the guide bar 2 via the rod 3.

FIG. 4 and FIG. 5 show an operating state when no overlap occurs. In FIG. 4, the gauge piece 25 is selected,
In this state, the pressing body 27 is displaced with a constant displacement amount in the direction of the arrow as shown in FIG. It does not come into contact with the piece 25, so that no action is taken until the transmission rod 6 is displaced by the overlap.
21 also remains stationary.

FIGS. 6 to 8 show an operation state of performing an overlap displacement (a displacement from left to right on the drawing) in the pulling direction of the guide bar 2 (the direction in which the guide bar 2 is pulled by the sig lever 4). The transmission rod 6 acts on the side (not shown). At the position shown in FIG. 6, the selected gauge piece 26 falls, and further, as shown in FIG. 7, the pressing body 28 moves in the direction of the arrow to the position of the starting point of the overlap. A necessary portion of the multiple gauge piece 9 for lap falls to perform underlap.

Next, as shown in FIG. 8, the pressing body 28 is displaced in the direction of the arrow to the position of the end point of the overlap by the action of the cam 38, whereby the sig lever 4 is rotated rightward in the drawing. From the left side to the right side.

FIGS. 9 and 10 show a state in which no overlap occurs in the above displacement direction. In FIG. 9, the gauge piece 26 is maintained at the upper position without being selected and dropped, and in this state, the pressing body 28 is moved to the pitch corresponding to the knitting machine gauge, that is, the position corresponding to the position in FIG. To the left of the drawing (FIG. 10), but does not act on the gauge piece 26, and thereafter the movement of the transmission rods 6, 7 is restricted by the contact engagement between the fixed part 24 and the floating member 22. Only the displacement of the underlap due to the selective drop of the multiple gauge piece 9 is made, and no overlap displacement is generated.

As described above, it is possible to select an overlap in an arbitrary knitting course for the guide bar 12, and in particular, if the above-described configuration is applied to the floating guide bar in the drop plate knitting, various Can be created.

In this case, for each of the guide bars 2 arranged in parallel, a pair of gauge pieces 25 and 26 respectively contacting the floating members 21 and 22 are arranged, and the pressing members 27 and 28 which perform a pressing operation integrally form the respective guide bars 2. It is configured so that a displacement movement can be simultaneously given through the floating members 21 and 22.

FIG. 11 shows another embodiment of the driving unit in the summing mechanism, and members having the same configuration as those of the above-described embodiment are denoted by the same reference numerals.

Upper summing mechanism 1A and lower summing mechanism of this embodiment
The drive mechanism of 1B has basically the same configuration.

Describing the configuration of the drive unit of the upper summing mechanism 1A, reference numeral 125 denotes an overlap gauge piece, and reference numeral 154 denotes a lever as a pressing member for the gauge piece 125. The lever 154 is swingably supported on a fixed support shaft 155, and a cam roller 16 provided at one end of its end (lower end in the figure).
0 contacts the drive cam 151 fitted to the cam shaft 150, and the pressing roller 161 provided at the other end contacts the end face when the gauge piece 125 is lowered.

As for the drive unit of the lower summing mechanism 1B, a lever 156 as a pressing member for the overlap gouge piece 126 is swingably supported by a fixed support shaft 157, and is fitted to the cam shaft 152 at its end. A cam roller 158 that comes into contact with the driven cam 153 and a pressing roller 159 that comes into contact with an end surface of the gauge piece 126 when it descends.

In the upper summing mechanism 1A, rotation is transmitted to a pulley 162 on a cam shaft 150 via a timing belt 164 by a drive shaft (not shown) which is driven to rotate in synchronization with the main shaft. The drive cam 151 rotates.
The drive cam 151 is provided with a displacement (amount of overlap) of one gauge by increasing the overlap timing portion in the circumferential direction. The cam roller 160 abutting on the drive cam 151 causes the lever 154 to move to a predetermined position. It swings at the timing, and the displacement of the overlap is transmitted to the floating member 21 via the gauge piece 125 by the pressing roller 161 for the swinging operation.

Further, in the lower summing mechanism 1b, rotation is transmitted to a pulley 163 on a cam shaft 152 via a timing belt 164, and a driving cam 153 is rotated by the cam shaft 152. The corresponding overlap timing portion located at a position opposite to the position 151 is lower by one gauge, contrary to the above. Therefore, the lever 156 is moved at a predetermined timing through the cam roller 158 which comes into contact with the lever 156.
Swings, the swinging movement of the floating member 22 pressing through the gauge piece 126 moves to the end point of the overlap, and as a result, the sig lever rotates to the right side in the drawing, and the guide bar Is given an overlap displacement from the left side to the right side of the drawing.

As described above, the levers 154 and 156 driven by the cams are used as the pressing members that press through the gauge pieces 125 and 126 that selectively contact the floating members 21 and 22, respectively. The same effect as in the case is achieved.

That is, also in this embodiment, the gauge piece 125,
By the action and the ineffectiveness of 126, the displacement amount necessary for the overlap can be given to the sig lever via the transmission rods 6,7.

According to this embodiment, the driving means for driving the pressing body is simplified as compared with the above embodiment, and the structure is further simplified as compared with the above embodiment.

In the illustrated embodiment, the case where the jacquard head 10 is used as the selection means for selectively causing the gauge pieces 25, 26 or 125, 126 to abut against the floating members 21, 22 has been described. As the above-mentioned selection means, it is possible to use various mechanisms capable of selectively causing the gauge piece to abut against the floating member, for example, selectively making the gauge piece abut against the floating member using a solenoid. it can.

[Industrial applicability]

According to the present invention as described above, in a guide bar drive control device of a warp knitting machine using a summing mechanism, a gauge piece that operates based on a command from a selection unit as appropriate as an underlap is used as a selection unit, Since the pressing member driven simultaneously through the gauge pieces is configured to selectively apply a motion corresponding to the overlap displacement to the transmission rod, the selecting device is simplified, the device is made compact, and the space is saved. In addition, various patterns can be formed by the summing mechanism.
