Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cover for covering a movable part of a flat knitting machine, including a carriage that moves over the needle bed, together with the needle bed.

〓Conventional technology〓 In a flat knitting machine, during the movement of the carriage or other movable parts on the needle bed, an injury accident may occur where a part of the body is placed in the movement trajectory and comes into contact with the carriage, etc. There is. Furthermore, for some reason, an object may fall onto the needle bed, damaging the knitting machine, or becoming woven into the knitted fabric. In addition, the carriage was also a source of noise due to contact between the cam and the butts of needles, etc.

To this end, it is conceivable to provide a cover that covers the needle head and carriage of the flat knitting machine. As an example of the cover, a guide rail is provided parallel to the needle bed in the longitudinal direction of the needle bed, that is, in the left and right direction of the flat knitting machine, and the guide rail divides the knitting machine into multiple widths in the width direction. A cover formed by supporting a plurality of covers in a sliding door manner is conceivable.

This cover can cover the carriage and the needle bed, but the needle bed or
When uncovering a portion of the carriage, it is sufficient to move the cover of that portion to the left or right in a sliding door manner, but it is not possible to attempt to expose the entire covered portion from the cover at the same time. That is, for example,
If the knitting machine is covered with four covers,
Even if all four covers are moved to the left or right end of the knitting machine, the four covers will overlap in that area, and a quarter of the width of the knitting machine will be covered by the covers. Therefore, the entire width of the knitting machine cannot be exposed at the same time.

〓Problems to be Solved by the Invention〓 In a flat knitting machine equipped with a cover that covers movable parts such as a needle bed and a carriage, when the cover is opened, part of the open cover always covers the needle bed, the carriage, etc. It is an object of the present invention to provide a cover that can be removed from the entire front surface of movable parts such as a needle bed and a carriage so as not to impede their operation.

〓Means for solving the problem〓 A movable member including the carriage is mounted on a cover support member that is supported by a guide member so as to be movable forward and backward relative to the front of the knitting machine above the carriage that moves on the needle bed of the knitting machine. A cover that covers the needle bed and the needle bed is rotatably supported.

〓Operation〓 The cover is supported by a cover support member so as to be able to be pulled out forward on the flat knitting machine stand.

When opening the cover, the tip of the cover is lifted and rotated, and as the cover moves, the lock of the stop claw of the cover support member is released. When the cover is pushed toward the rear of the machine, a stop claw comes out from the notch of the positioning stopper member, allowing the cover to be positioned at the rear of the knitting machine. Pushing the cover to the rear of the machine will remove the covering of moving parts such as the carriage and the needle bed.

Conversely, when covering each of the above parts with a cover, if the cover is pulled out toward the front of the knitting machine, the stop claw of the cover support member will fit into the notch of the positioning stopper member, and the end of the cover will hang down to release the stop claw. to make the cover support member immovable.

〓Example〓 An example of implementation of the device of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an example in which a flat knitting machine 2 in which a carriage 1 reciprocates the upper part of a needle bed (not shown) provided with a chevron-shaped top facing each other is shown in FIGS.

Stand 4 installed at the back of machine stand 3 of flat knitting machine 2
The reciprocating direction of the carriage 1 (Fig. 1,
A guide rail 5 extending in a direction perpendicular to the paper plane (in FIG. 2) is provided together with a positioning stopper member 7 for a cover support member 6, which will be described later. A slide pack 9 having a mounting plate 8 is supported on the guide rail 5. The slide pack 9 slides on the guide rail 5 by fitting ball bearings 10 provided on both sides into the curved surface portion 11 of the guide rail 5. A cover support arm 13 is fixed to the mounting plate 8 via a base 12.

A stop pawl 14 is swingably supported on the side surface of the base 12 by a bolt 15, and a spring 18 hung on the stop pawl 14 and pins 16, 17 provided on the base 12 allows the stop pawl 14 to be supported as shown in FIG. Force it to rotate clockwise. A switch 19 is provided close to the stop pawl 14,
It is detected whether the stop pawl 14 has swung.

A block 21 is fixed to the tip of the cover support arm 13 with a bolt 29. A cover mounting member 22 having a triangular side surface and a U-shaped horizontal cross section is swingably supported on the block 21 by a shaft 23. The frame 25 of the upper cover 24 is attached to the cover attachment member 22 by appropriate means. A sliding rod 26 is pivotally supported on the side surface of the cover mounting member 22. A long groove 27 is provided at the other end of the sliding rod 26, and the long groove 2
The sliding rod 26 is supported on the base 12 by screwing a screw 28 into the long groove 27 so as to be slidable therein.

A cover 3 is attached to the side of the needle bed (not shown).
1 and supported by a support arm 32
The lower cover 34 is supported so as to be able to swing freely around the center.
35 is an operating rod for driving the knitting machine. The lower cover 34 is also provided with a switch which is activated when the lower cover 34 is opened to stop the drive of the knitting machine.

During normal knitting, as shown in FIG. 1, the upper cover 24 is pulled out to the front of the knitting machine, with the tip facing downward, and the lower cover 34 pivots around the shaft 33, with the end positioned upward. It covers movable parts such as a needle bed, a carriage, and a carriage 1 (not shown).

Now, if a situation arises in which a worker has to insert his or her hand or other object into the cover, the lower cover 34 can be manually moved counterclockwise in FIG. 1 around the shaft 33. The upper cover 24 is rotated to the state shown in FIG. 2, and the top cover 24 is manually rotated clockwise around the shaft 23 at its tip. This frees the front surface of the knitting machine, but the upper cover 24 protrudes toward the front of the knitting machine, causing a nuisance during operation, so it is necessary to retreat the protruding upper cover 24. Upper cover 24
When the cover mounting member 22, which is integral with the frame 25, rotates around the shaft 23 in a clockwise direction in FIG.
Pull the sliding rod 26 to the left in Figure 1. As a result, the end of the sliding rod 26 and the stop pawl 14 are disengaged, and the stop pawl 14 becomes able to pivot counterclockwise in FIG. In this state, when the upper cover 24 or the cover support arm 13 is pushed toward the rear of the knitting machine, the stop claw 14 comes off from the notch 20 of the stopper member 7 due to the action of the tapered portion at its tip, and the stopper claw 14 separates from the positioning stopper member 7 and the stopper member 7. The engagement with the claw 14 is severed. Therefore, the cover support member 6 can be manually pushed to the rear of the knitting machine. As a result, the slide puck 9 of the cover support member 6 moves toward the rear of the knitting machine along the guide rail 5, and the upper cover 24 assumes a position that does not interfere with the work. Above upper cover 24
Due to the rotational movement of the stop pawl 14, the stop pawl 14 engages the
When it escapes from the switch 1, the stop claw 14
9, the drive device of the knitting machine is stopped, and the knitting machine is stopped.

Contrary to the above, when covering with the cover 24, as shown in Fig. 2, the upper cover 24 is pulled into the upper part of the knitting machine.
4 Or, when the cover support arm 13 is held and pulled out, the cover support member 6 moves with the top of the stop pawl 14 positioned and in contact with the stopper member 7, and the stop pawl 14 and the recessed notch 20 engage with each other. Therefore, stop the drawer at that position. At this time, the long groove 27 is most advanced relative to the screw 28, and the end of the sliding rod 26 is not at the lower end of the stop pawl 14.

Then, when the upper cover 24 is turned clockwise, the sliding rod 26 moves to the right, and by positioning its end below the stop pawl 14, it prevents the stop pawl 14 from falling unintentionally. , the cover 24 cannot be moved unless the upper cover 24 is turned clockwise.

〓Effects of the Invention〓 When the device of the present invention covers movable knitting parts of a knitting machine such as a needle bed and a carriage, the cover for that purpose is pulled out from the upper part of the knitting machine stand, covers the front of the knitting machine, and When exposing a part, the cover can be stored by pushing it into the upper part of the knitting machine, so the entire width of the knitting machine can be opened or covered at the same time, and the cover can be opened like a sliding door like in conventional machines. It is possible to eliminate the situation where the sheets are stacked one on top of the other, occupying a part of the front of the knitting table and hindering the work.

It also prevents the scattering of dust and has the effect of preventing noise.
