Description

Technical Field

[0001] The utility model relates to a flat knitting machine which takes the length direction of a needle bed as the knitting width direction. Background Art

[0002] In the past, a flat knitting machine has a plurality of needle grooves arranged in parallel on the needle bed, and the knitting needles accommodated in each needle groove are moved forward and backward in the tooth gap to knit the knitted fabric. The knitting needles are driven by a cam carried by a carriage that reciprocates in the knitting width direction. When knitting knitted fabrics on a flat knitting machine, sometimes adjustments are required to knit a knitted fabric of good quality. When adjusting, it is necessary to switch the carriage speed to a speed lower than the speed during normal knitting to confirm the movement of the knitting needles.

[0003] In recent years, a flat knitting machine having an operation panel capable of performing various operations including switching of operating conditions and displaying the operating conditions has been used (see, for example, Patent Document 1). The operation panel of Patent Document 1 is fixed to one side in the knitting width direction, and the front cover is inclined forward.

Corresponding parts in each figure are indicated by the same reference numerals, and repeated descriptions are sometimes omitted. In addition, for the convenience of description, there are parts that are omitted from the illustration.

[0048] [Example]

[0049] Figure 1 The flat knitting machine 1 shown has a flat knitting machine body 10, with the horizontal direction of the figure being the weaving width direction, and having a needle bed 2 with a plurality of needle grooves arranged in parallel. The carriage 3 is driven by a belt from a driving unit 4, etc., so that the carriage 3 reciprocates in the weaving width direction while using the carried cam to move the knitting needles accommodated in each needle groove forward and backward in the tooth gap to weave the knitted fabric. The various parts of the flat knitting machine body 10, such as the needle bed 2 and the driving unit 4, are supported by a frame 11. A top spring support part 13 is provided above the ceiling plate 12. The top spring support part 13 arranges and supports a top spring device for adjusting the tension of the knitting yarn supplied to the knitting needles when the knitted fabric is knitted. It should be noted that in Figure 1 In the figure, the front-to-back direction of the paper is set as the front-to-back direction, the horizontal direction of the paper perpendicular to the front-to-back direction is set as the left-right direction, and the top-to-bottom direction of the paper is set as the top-to-bottom direction.

[0050] The ceiling plate 12 is also used to carry a plurality of yarn packages. The operation state of the flat knitting machine 1 is controlled by the control unit 5 supported by the frame 11. A safety cover 14 that can be opened and closed is provided on the front side of the flat knitting machine body 10. The knitting of the knitted fabric is performed as an automatic operation according to the knitting data prepared by the design system, etc., in normal knitting with the safety cover 14 closed. Normal knitting is performed at a carriage travel speed of, for example, 1.2 m / s, which can efficiently knit the knitted fabric.

[0051] The flat knitting machine body 10 includes an operation panel 6 provided on the ceiling plate 12. The operation panel 6 includes an input unit 61 ( Figure 4 The input unit 61 is provided with a display panel 62, which displays the operation state based on the operation of the input unit 61. The display panel 62 has not only the function of displaying images, but also the function of inputting as a touch panel. The input unit 61 has various switches, etc. The operation panel 6 can communicate with the control unit 5. The control unit 5 controls the operation state of the flat knitting machine 1 based on the operation of the input unit 61 and displays it on the display panel 62.

[0052] The operation panel 6 is arranged at the center of the left and right directions of the ceiling board 12, and the operation panel 6 is easily accessible from any left and right positions, which is conducive to improving operability. It should be noted that the operation panel 6 can of course be arranged near the center of the left and right directions of the ceiling board 12, and can also be arranged at any position of the left and right directions of the ceiling board 12.

[0053] A pair of left and right sliding mechanisms 7, 7 (in the left and right sides) are provided below the top plate portion 15 of the ceiling plate 12 for sliding the operation panel 6 in the front and rear directions relative to the ceiling plate 12. Figure 5 ). Through the sliding mechanisms 7, the yarn package can be placed on the top plate 15 without being blocked. Furthermore, when the operation of the flat knitting machine 1 is adjusted, if the operating panel 6 is slid forward away from the ceiling plate 12 by using the sliding mechanism 7, the operator can easily approach the operating panel 6, which can improve the operability of the operating panel 6.

[0054] Figure 2 to Figure 6: represents a structure related to the sliding mechanism 7. The sliding mechanism 7 is provided between a supporting frame 63 (operating panel 6 side) supporting the operating panel 6 and a top plate portion 15 (top plate 12 side) of the ceiling plate 12. The supporting frame 63 is supported by the sliding mechanism 7 so as to be freely slidable in the front-rear direction relative to the top plate portion 15. The supporting frame 63 extends in the front-rear direction in a state of being formed into a substantially "U"-shaped cross section opening downward, and a lower end of a supporting arm 64 extending in the upward and downward direction is fixed to the front end thereof. The upper end of the supporting arm 64 is supported on a bracket 65 protruding from the rear surface of the operating panel 6 via a shaft 66 extending in the left-right direction, so that the operating panel 6 can be swung in the upward and downward direction. It should be noted that the upper end of the supporting arm 64 can also be supported on the bracket 65 via a shaft extending in the upward and downward direction in addition to the shaft extending in the left-right direction, so that the operating panel 6 can be swung not only in the upward and downward direction but also in the left-right direction.

[0055] At the left-right center of the lower surface of the top plate 15, the horizontal surfaces of L-shaped brackets 16, 16 extending in the front-rear direction with their vertical surfaces facing each other toward the inner side surfaces are fixed. Each sliding mechanism 7 includes an outer rail 71 fixed to the inner side surface of the vertical surface of each L-shaped bracket 16 and an inner rail 72 fixed to the outer side surfaces of the left and right sides of the support frame 63. In addition, each sliding mechanism 7 includes an intermediate rail 73 slidably provided between the two rails 71, 72 via a sliding ball 74 rolling between the two rails 71, 72, and the operation panel 6 can slide smoothly with a small force through each slidable rail 71 to 73. Reference numeral 75 is a retainer for positioning the sliding ball 74 at the optimal position between each rail 71 to 73. It should be noted that the inner rail 72 may be provided on the ceiling plate 12 side and the outer rail 71 may be provided on the operation panel 6 side.

[0056] A position holding mechanism 8 is provided between the operation panel 6 and the ceiling plate 12 for holding the position of the operation panel 6 at four sliding positions in the front-rear direction relative to the ceiling plate 12. The position holding mechanism 8 includes a pressing receiving portion 81 having a substantially rectangular cross-sectional shape extending in the front-rear direction, and a ball plunger 84, which can slide the operation panel 6 with a small resistance, and the ball plunger 84 includes a pressing ball 83 that slides on the lower surface 82 (pressing surface) of the pressing receiving portion 81 while being pressed against the lower surface 82.

[0057] like Figure 5As shown, the push receiving portion 81 is fixed to the lower surface of the support frame 63 located in front of the outer rail 71 on the left side of the outer rail 71 in the right sliding mechanism 7 and extends rearward. The ball plunger 84 is fixed to the lower surface of the top plate 15 located in front of the outer rail 71 on the left side of the outer rail 71 in the right sliding mechanism 7 via the hook-shaped bracket 17. It should be noted that the push receiving portion 81 can also be fixed to the ceiling plate 12 side, and the ball plunger 84 can be fixed to the operation panel 6 side.

[0058] On the lower surface 82 of the pressing receiving portion 81, four recessed portions 85 are provided at equal intervals in the front-to-back direction corresponding to the four sliding positions of the operating panel 6. When the pressing ball 83 of the ball plunger 84 is embedded in the recessed portions 85 of the lower surface 82 of the pressing receiving portion 81, the position of the operating panel 6 corresponding to each sliding position can be smoothly maintained each time the sliding in the lower surface 82 is stopped. In addition, when the operating panel 6 is not in use, if the operating panel 6 is slid to the rear near the ceiling plate 12 and the pressing ball 83 is embedded in the frontmost recessed portion 85, the operating panel 6 can also be retreated in a manner that does not hinder maintenance operations. It should be noted that the sliding positions of the operating panel 6 held in position by the position holding mechanism 8 are not limited to four, and can be any number as long as it is one or more.

[0059] The position holding mechanism 8 can smoothly perform input operation without releasing the position holding of the operation panel 6 due to the operation force on the input unit 61. On the other hand, by the action of an external force greater than the operation force on the input unit 61, for example, by an external force applied by an operator to forcibly slide the operation panel 6 in the forward and backward directions, the pressing ball 83 is disengaged from the recessed portion 85, and the position holding of the operation panel 6 by the position holding mechanism 8 is released, so that the position holding of the operation panel 6 can be smoothly released.

[0060] It should be noted that in this embodiment, a pair of left and right sliding mechanisms 7, 7 having rails 71 to 73 and sliding balls 74 are used, but a simple sliding mechanism consisting of an outer rail, an inner rail and sliding balls, or a sliding mechanism using a single or a pair of left and right linear guides may also be used.

[0061] In addition, the slide mechanism 7 is not limited to manual, and the operation panel 6 may be automatically slid forward and backward by a drive source such as a motor. In this case, the position of the operation panel 6 at the sliding position may be maintained by a position maintaining mechanism such as an electromagnetic brake.

[0062] Furthermore, the position holding mechanism 8 may be configured to hold the operation panel 6 in position at any of a plurality of sliding positions by a pressing force such as a pressing screw. In addition, the position holding mechanism 8 may hold the operation panel 6 in position by inserting a claw urged by a spring into a recess, a cutout, etc. on the pressing surface instead of the ball plunger 84.
