Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knitting presser device for a V-bed flat knitting machine, and more specifically, the present invention relates to a knitting presser device for a V-bed flat knitting machine. A pair of needle beds are arranged in an inverted V-shape to form a opening, and on top of the pair of needle beds is a carriage that integrally connects a pair of cam boxes equipped with knitting cams that act on the knitting needles. In a V-bed flat knitting machine that is arranged to freely reciprocate, the knitted fabric can be pulled downward from below the opening using a weight or a knitted fabric pull-down device, etc. The present invention relates to a knitted fabric holding device that can lower the knitted fabric from the edge of the knitted fabric.

In order to achieve the above objectives, several knitted fabric pressers have already been developed and are known, but the known knitted fabric pressers can be roughly divided into two types.

One of them is a pair of horizontal members installed on a carriage that connects a pair of cam boxes, spanning between the front and rear cam boxes, and a support device installed across the left and right horizontal members. an arm supported on the support device and capable of pendulum movement along the longitudinal direction of the needle bed;
At the lower end of this arm is attached the central part of a knitted fabric presser which is V-shaped when viewed from the front. In this type of system, at the turning point of the reciprocating movement of the carriage,
A pendulum motion is applied to the arm, and when the carriage moves to the right, the left half of the knitting presser foot, which is V-shaped in front view, is brought into sliding contact with the knitted fabric, and when the carriage moves to the left, the right half slides against the knitted fabric. By applying the contact action, a knitted fabric pressing action is performed that covers the reciprocating stroke of the carriage. A knitting presser device in which such a V-shaped knitting presser is moved in a pendulum manner is disclosed in, for example, Utility Model Application No. 49-30657 and Japanese Patent Publication No. 1983-1989.
No. 42167 and Japanese Patent Publication No. 55-42168 have already become publicly known.

Another method of the known knitted fabric presser is a method previously developed by the present inventor (Utility Model Application Publication No. 139748, 1982).
The fabric presser that covers the reciprocating stroke of the carriage is installed on one cam box side, and only when the carriage moves back and forth, the L-shaped fabric presser enters the opening between the pair of needle beds. The forward knitting fabric holding device slides on the knitted fabric, and the carriage attached to the other cam box is L only when the carriage goes back.
It is composed of a combination of a pair of single-stroke knitting fabric pressers and a back-stroke knitting fabric presser in which a letter-shaped fabric presser enters the opening between a pair of needle beds and slides into contact with the knitted fabric. It is something that exists.

However, these known knitted fabric pressing devices each have the following advantages and disadvantages.

That is, the former knitting presser device, which moves a knitting presser having a V-shape when viewed from the front in a pendulum motion to change the working direction of the knitting presser, is disclosed in Japanese Patent Publication No. 55-42167, for example.
According to the invention disclosed in the publication, if a pendulum motion is given to the knitting presser, there is no need to give the carriage an extra motion exceeding the length of the needle bed in order to give the pendulum motion to the knitting presser. , and other advantages are given.

However, in order to hold this V-shaped knitted fabric presser in its working position, a pair of horizontal members installed across the front and rear cam boxes, and a bridge between the pair of horizontal members are required. A support device is attached to the needle bed, and an arm supported by the support device so as to be movable in a pendulum manner. In flat knitting machines equipped with this type of fabric presser, the upper part of the opening along the longitudinal direction of the needle beds between a pair of needle beds is , the support device;
It must always be open for the passage of the arms extending downward from the support device.

Therefore, in a V-bed flat knitting machine equipped with this type of fabric holding device, it is also possible to install the thread guide rail of the thread guide device in the space directly above the opening. The drawback was that the thread rod could not be moved. That is, in a pattern knitting device that requires as many thread guide rails as possible and as many thread guide rods as possible, there is a drawback that there are restrictions on the number of thread guide rails and the number of thread guide rods that can be provided. It was hot.

In addition, in this type of V-shaped fabric presser, the non-active side when the carriage is running always springs up obliquely upward in the direction of travel, above the opening. Since its width is larger than the arm to which it is attached, it also has the disadvantage that when the carriage is running, its inactive side tends to come into contact with the resting thread guide rod, causing trouble. Ta.

In this respect, an L-shaped knitting presser that can be advanced to the working position only when the carriage is running in one direction is provided on one cam box side, and an L-shaped fabric presser that can be advanced to the working position only when the carriage is running in the other direction is installed on one cam box side. In the latter fabric presser device, in which the fabric presser is provided on the other cam box side, the L-shaped fabric presser is placed in a position with its vertical portion substantially parallel to the needle groove of the needle bed on the opposite side. The base end (the upper end of the vertical part) is attached to a support device provided on the cam box on the needle bed, and the vertical part is bent downward from the middle. , this knitting fabric presser has a horizontal portion on its distal end inserted into an opening between a pair of needle beds, and is in an advanced position (fabric presser action) where it extends laterally within the opening. position) and the position where the horizontal part of the knitting presser foot escapes from the opening and approaches the top surface above the needle bed on the front side, and at a position where it does not interfere with the knitting needles rising from the needle bed on the opposite side. Since the knitting presser device of this type is configured to be able to move back and forth freely between the retracted position (the position where the knitting presser is not activated) and the retracted position (the position where the knitting presser is not activated), In terms of direction, it only covers the area slightly higher than the height of the top tooth.

Therefore, this type of knitting presser uses an open space above the opening, as opposed to the former knitting presser, in which the V-shaped fabric presser is provided with a pendulum movement through the opening. , it has the advantage that a larger number of thread guide rods can be run in the space by making full use of it and installing a thread guide device there.

However, in this type of knitted fabric presser, the L-shaped horizontal part, which is the presser acting part that slides on the knitted fabric, advances and retreats only in the direction along the needle groove, and the opening of the pair of needle beds, that is, the Since the knitting presser foot is moved in and out between the top teeth of the needle bed of This had the disadvantage that this could only be done from a position exposed outside the opening between the needle beds. In other words, the known knitting presser of this type requires that the carriage always be reciprocated for its entire stroke (longer than the length of the needle bed), regardless of the size of the knitted width. It had some drawbacks.

An object of the present invention is to improve a knitted fabric presser belonging to the latter type, and to eliminate the above-mentioned advantages that the latter type knitted fabric presser has, which the former type knitted fabric presser does not have. The present invention aims to eliminate the disadvantages of the latter type of knitted fabric presser while making the most of the above, and to provide this with the same advantages as those of the former type of knitted fabric presser.

In the fabric holding device of the V-bed flat knitting machine of the present invention which solves these problems, the fabric holding device that covers the reciprocating stroke of the carriage is installed in one of the cam boxes, and knits only when the carriage moves back and forth. There is a forward knitting fabric presser in which a presser enters the opening between a pair of needle beds and slides into contact with the knitted fabric, and a pair of fabric pressers installed in the other cam box only when the carriage goes back. and a back-stroke knitting fabric presser that enters the opening between the needle beds and slides into contact with the knitted fabric, and a pair of single-stroke knitting fabric pressers. The holding device includes a support device attached to the front upper surface of the cam box, and a support device mounted on the support device approximately in the needle groove of the lower needle bed of the cam box on the opposite side of the cam box to which the support device is attached. A pair of upper and lower sliding metal fittings are each slidably supported along parallel directions, and the base end is pivoted to the tip of the lower sliding metal piece, and the upper free end side is supported as above. a knitting fabric presser attachment fitting connected to the tip of the upper sliding fitting; a knitting fabric presser having its base end attached to the upper end of the knitting fabric presser fitting; and the pair of sliding fittings. The fabric presser has an L-shape, and the fabric presser is attached to the mounting hardware at a portion corresponding to the upper part of the vertical portion of the L-shape. The lower part of this vertical part is bent downward near the mounting hardware, and the horizontal part at the tip is inserted into the opening between the pair of needle beds. It constitutes a knitted fabric presser action section extending along the longitudinal direction of the opening, and the advancing and retracting drive device of the pair of sliding metal fittings is engaged with a pin protruding from each sliding metal fitting and each pin, respectively. The grooved cam plate has a pair of mating cam grooves and is slidably supported along the longitudinal direction of the needle bed by the support device, and the pair of cam grooves are connected to the upper and lower pair of cam grooves. The sliding hardware is moved back and forth to give the tip of the knitting press a forward and backward movement with an arc movement that exceeds the upper direction of the top tooth, Equipped with a cam surface that allows entry and exit from above into the opening between the floors;
It is characterized by:

According to the present invention, the knitting fabric presser device configured as described above uses the horizontal portion of the L-shaped fabric presser to control the lasing action area of the knitting cam group provided in the cam box in the width direction of the carriage. When the raising action areas of the transfer cam groups are respectively covered and installed on the support device, the loops hanging on the knitting needles pushed up by the raising cams of these cam groups will cause the raising of the knitting needles. This can be suppressed by using the horizontal portion of the knitting presser located at the working position.

However, on the cam box, there is a brush that is placed almost in line with the raising action area of the group of normal knitting cams to keep the tongues of the knitting needles raised from the needle bed on the opposite side by the action of the raising cams in an open position. The bristles are arranged so that they can come into contact with the tongue of the knitting needle that is raised from the opposite needle bed, with the tips of the bristles facing the top teeth of the opposite needle bed.

Therefore, when the fabric presser according to the present invention is disposed in the raising action area of the knitting cam group in the width direction of the carriage, the horizontal portion of the fabric presser is the same as this brush. Therefore, if the brush is fixed and installed on the cam box as in the conventional device, the knitted fabric presser device of the present invention installed in this phase will have a horizontal part of the knitted fabric presser. , when it retreats from the opening between the needle beds, which is its forward action position, when it moves in an arc over the upper teeth, it collides with the bristles of the brush, causing the bristles of the brush to There is a risk of deformation.

Another object of the present invention is to prevent the bristles of the brush from being damaged even when the horizontal part of the knitted fabric presser moves back from the knitted fabric presser working position to the non-working position by performing the circular arc motion as described above. , it is an object of the present invention to provide a knitted fabric pressing device.

In the knitted fabric presser device of the present invention which also solves these problems, a brush is provided on the support device in substantially the same phase as the horizontal portion of the knitted fabric presser in the width direction of the cam box. The brush is attached to the tip of the brush mounting hardware that is slidably supported in a direction substantially parallel to the upper and lower sliding hardware, and the brush acts on the knitting needles planted in the needle bed on the opposite side. The brush is configured to be movable back and forth between the working position and the non-working position, and a driving device for displacing the brush between the working position and the non-working position projects from the brush mounting hardware. and a cam groove formed in the grooved cam plate and engaged with the pin; It is equipped with a cam surface that temporarily retracts the brush from its working position.

According to this invention, upper and lower cam grooves 2 are provided for imparting the above-described movement to the knitted fabric presser foot 11.
7 and 28 are shown in detail in FIG.

The cam grooves 27 and 28 and the upper and lower rollers 31 and 32 that are moved forward and backward by the cam grooves 27 and 28 are connected to the grooved cam plate 17,
In the 18 operating directions (that is, the left and right directions), they are always in the same phase. Therefore, if the shapes of each pair of cam grooves 27, 28 are made different as shown in FIG. 10, the upper and lower rollers 31, 32 can be
At position A in each of the cam grooves 27 and 28, it is maintained at the most advanced position shown by a solid line in the figure. In this A position, the groove width of the upper cam groove 27 is the same as that of the lower cam groove 27.
It is slightly larger than the groove width of No. 8. Therefore, the upper roller 31 can move forward and backward slightly within the cam groove 27. However, the upper sliding hardware 15 is
Since the upper roller 31 is always biased toward the relatively forward position by the spring 35 stretched between the lower sliding hardware 16, the lower roller 32 The upper sliding metal fitting 15 is kept in the most advanced position, and the knitted fabric presser 11 is kept in the most advanced position, as shown in FIG. 9-A. In this position, the lower part of the L-shaped vertical portion of the fabric presser 11 is bent downward 11b to approach the attachment hardware 23 of the fabric presser as described above.

In addition, regarding the knitted fabric presser device of this example,
The width of the upper cam groove 27 is made larger than the diameter of the roller 31 at the A position, and a spring 35 is installed between the upper and lower sliding metal fittings 15 and 16, so that the knitted fabric The presser foot 11 moves in a circular arc against the urging force of the spring 35 in the forward direction within the range where the upper roller 31 can retreat to position B shown by the chain line in FIG. The presser action portion 11c can be raised to the position shown in FIG. 9-B and released.

Therefore, in the most advanced position of the lower sliding metal fitting 16 shown in FIGS. 9A and 9B, the knitted fabric presser 11
The pivot point 24 of the mounting hardware 23 is configured to be located approximately on the extension of the imaginary line XX connecting the upper ends of the needle grooves of the pair of needle beds 2f, 2r.

A pair of cam grooves 17 and 18 act on the upper and lower rollers 31 and 32, respectively, to move the upper sliding metal fitting 17 and the lower sliding metal fitting 18 backward from the above-mentioned phase A in which both are kept at the most advanced position. Cam slope 2 for
As shown in FIG. 10, the grooved cam plate 7a and 28a have different phases.
7 and 18 to the upper left in FIG. 10, only the upper roller 31 moves forward while the lower roller 32 is still held in the forward position by the cam groove 28a. The lower roller 32 does not start retracting until it is retracted by a certain amount by the cam groove 27a, and the upper and lower rollers 31, 32 move to the phase C shown in FIG. At the time when the knitting presser foot 11 reaches this point, the acting part 11c of the knitted fabric presser 11 moves in an arc and escapes from the opening 4 (FIG. 9-C), and then the lower roller 32 starts to retreat for the first time. By doing so, the upper and lower sliding metal fittings 15 and 16 are
In this way, after the phase D in FIG. 10 (FIG. 9-D) in which the working part 11c of the knitted fabric presser 11 has passed above the top teeth 40, the upper slider is moved backward at the same speed. By lowering the backward speed of the moving hardware 15 to be lower than the backward speed of the lower sliding hardware 16, the knitted fabric presser foot 11 is given circular motion again, and the upper and lower rollers 31, 32 reach phase E in FIG. At this point, as shown in FIG.
It is located below the extension line of the bottom of the needle groove (Fig. 9-E), and can be moved backward without going above this extension line.

Note that the cam grooves 27 and 28 shown in FIG.
When the knitted fabric presser device according to the present invention is implemented in the action area of the knitting cam group 8, the knitted fabric presser 11
In order to prevent the working part 11c from interfering with the brush 41, which is provided on the cam box 5f so that its working area is almost the same as that of the working part 11c, it is constructed as follows. That is, cam groove 2
7 and 28, in the phase F shown in FIG. 10, the lower cam groove 28 is displaced backwards than the upper cam groove 27, and when the rollers 31 and 32 reach the above phase F, , the lower sliding metal fitting 16 is relatively moved back more than the upper sliding metal fitting 15, and as shown in FIG. It is designed so that it can be lowered further down than the position shown in Figure 9-E.

From the state shown in Fig. 9-F above, the grooved cam plates 17, 1
8 to the upper right in Fig. 10, the knitting presser foot 1
1 moves forward with a circular arc movement opposite to that described above, and passes over the top tooth 40 to the pair of needle beds 2f, 2.
Needless to say, it is forced into the gap 4 between r.

The trajectories of the knitting presser foot 11 corresponding to the phases A to F are shown in dashed lines in FIG.

According to the present invention, the knitted fabric presser device 1 has the working part 11c of the knitted fabric presser 11 move back and forth in the above-described trajectory, so that the knitted fabric presser device 1 can be
When applied to the action area of the knitting cam group 8, when the action part 11c of the knitting fabric presser foot 11 passes over the top tooth 40 in an arcuate trajectory, it In phase,

Therefore, in the knitted fabric presser 1 of the present invention, which is provided at the position where such a brush 41 is present, in other words, in the embodiment, the knitted fabric presser is provided at the center of the cam box 5. 1, as shown in FIGS. 3 and 12, in the width direction of the cam box 5f, the brush 41 is provided in substantially the same phase as the action part 11c, which is the horizontal part of the knitted fabric presser 11. It is mounted on a brush mounting hardware 42 on the support device 12 as follows.

That is, the brush mounting hardware 42 is guided on both sides and the lower surface by a groove 43 formed on the support device 12 in parallel with the groove 13, and is placed over the groove 43 so that the support hardware 12 Its upper surface is guided by a guide plate 44 fixed above, and its lower surface is guided into a groove 43 above the grooved cam plate 17, and its tip is connected to a stepped portion e. It is guided by the slidable engagement between the groove 45 and the head 46a of the pin 46 protruding from the support device 12, and the upper part of the tip has a
The clip 47 consists of two members 47a and 47b for holding the base end of the brush 41.
The lower member 47b is also secured with bolts 48.

In addition, on the bottom surface of this brush mounting hardware 42,
A roller 49 is attached to the shaft, and the grooved cam plate 17 has a
A cam groove 50 into which this roller 49 fits is formed, and the brush 41 is integrated with the grooved cam plates 17, 1.
8 to the left and right to move the knitting presser foot 11 forward and backward, the knitting presser foot 11 moves forward and backward in conjunction with the forward and backward movements of the knitting presser foot 11.
When the horizontal portion 11c of the knitted fabric presser foot 11 approaches position C from position A in FIG. 11 during its backward movement,
It starts its backward movement, moves backward together with the fabric presser 11 while still maintaining a slight distance between it and the horizontal portion 11c of the fabric presser 11, and moves back together with the fabric presser 11, at least the horizontal portion 11c of the fabric presser 11 After reaching position D in FIG. 11, which exceeds the upper direction of the top teeth 40, the brush 41 once reaches the most retracted position and starts moving forward, and the bristles of the brush 41 move as shown in FIG. It passes above the horizontal portion 11c of the knitting presser foot 11 that has descended to the E position, and is returned to the operating position (advance position) again.

As can be understood from the above, the single-stroke knitted fabric pressing device 1f having the above-described configuration according to the present invention has integral grooved cam plates 17, 18,
When driven to the right or left, the action portion 11c consisting of the horizontal portion 11c of the knitting fabric presser foot 11f moves against the pair of needle beds 2.
