Description

  The present invention relates to an apparatus for adjusting the height of a frame of a loom.

  In the loom, if the loom is operated with the ridge frame height set improperly, problems such as defective opening and tearing of the fabric at the time of beating are likely to occur. For this reason, the operation | work which adjusts the height of a collar frame so that it strikes in the appropriate position of a collar is performed.

  For example, in the opening device of the loom shown in FIG. 9, a drive transmission mechanism is provided for each rib frame, and the movement of the reciprocating drive device is converted into the vertical movement of the rib frame by the drive transmission mechanism. Further, the drive transmission mechanism includes a portion that supports the left and right sides of the collar frame from below with an extendable rod. The telescopic rod can change the total height, but does not have a height adjusting mechanism, and is simply screwed with a bolt that holds the total height at a desired length.

  Therefore, if the bolt is loosened without supporting the collar frame, the collar frame will drop due to its weight reducing the overall height of the telescopic rod. For this reason, the height adjustment work of the heel frame requires two or more people, including the person who supports the heel frame and the person who turns the bolt, and the workability is poor.

  As a conventional technique that eliminates the need for a person to support the eaves frame, the eaves frame height adjustment mechanism is included in the drive transmission mechanism of each eave frame as part of the opening device, and the height adjustment mechanism is manually operated. Some exist (Patent Document 1, Patent Document 2).

Japanese Patent Laid-Open No. 11-107103 JP 05-230734 A

  Since both of these use a pair of left and right height adjustment mechanisms corresponding to the number of hook frames, the manufacturing cost of the opening device increases. In addition, since the height adjustment mechanism is a part of the opening device, the opening device with the height adjustment mechanism increases the number of parts and the structure becomes complicated compared to the opening device without the height adjustment mechanism. It is easy to break down.

  Further, the heel frame is heavier by including the height adjusting mechanism in the drive transmission mechanism. Therefore, the structure in which the height adjusting mechanism is fixed to the heel frame is inappropriate for speeding up and down the heel frame.

  The present invention was created in consideration of the above situation, and the problem to be solved is that the height adjustment work of the frame can be easily performed, and the manufacturing cost of the opening device can be reduced, and the opening device is less likely to break down. In addition, an object of the present invention is to provide a heel frame height adjusting device suitable for speeding up and down the heel frame.

  The present invention provides a drive transmission mechanism that is provided for each collar frame and connects the reciprocating drive device and the collar frame, and includes an opening device that includes a drive transmission mechanism configured to change the supporting height of the corresponding collar frame. It is assumed that the heel frame height adjusting device is used.

And the engagement means which can be engaged / disengaged with respect to the collar frame and is arranged on the side of the collar frame and engaged with the side stay of the collar frame at the time of the height adjustment work of the collar frame performed before the start of operation of the loom When being placed on the fixed part of the loom in the side of the heald frames height Ru is adjusted watching contains an elevating means for moving the engaging means in the vertical direction with respect to the fixed portion, said engagement means, The side stay can be engaged with the side stay so as not to be relatively displaceable in the vertical direction, and the engagement state can be released . In the present invention, the fixed portion of the loom refers to a portion that does not move in the vicinity of the side of the ridge frame whose height position is fixed to the frame of the loom.

  The engaging means may engage the hook frame from the side, but in order to engage the hook frame without engaging the special modification for engaging the hook frame and the engaging means, It is desirable to do the following: That is, the engagement means includes a gripping device that grips an arbitrary position of the collar frame.

  If the engagement means includes a gripping device that grips an arbitrary position of the frame, it is not necessary to make a special modification to the frame to engage the frame and the engagement unit. It does not affect the vertical movement of the frame.

  The elevating means may be provided with a drive device serving as a power source. However, in order to keep the manufacturing cost low, it is desirable to do as follows. That is, the elevating means is formed by forming one screw portion of the male screw portion or the female screw portion and screwing into the other screw portion of the screw portion formed in the engaging means in the one screw portion. A screw member, an operation portion for relatively rotating one screw portion of the screw member and the other screw portion of the engaging means, and a seat portion placed on the fixing portion of the loom. is there.

  In the case where the elevating means includes a screw member, an operation part, and a seat part, the manufacturing cost can be reduced at a lower cost than that provided with a driving device.

  The heel frame height adjusting device may be configured only by the engaging means and the lifting / lowering means. However, in order to further improve the efficiency of the heel frame height adjusting work, the following can be performed. desirable. That is, the heel frame height adjusting device includes a heel frame height measuring means for measuring the height of the heel frame.

  As long as it includes a heel frame height measuring means for measuring the height of the cocoon frame, it is not necessary to prepare a separate cocoon frame height measuring means, making it easier to adjust the height of the cocoon frame. Yes.

  Since the present invention includes engagement means that can be engaged and disengaged with respect to the eaves frame and elevating means that is placed on the fixed portion of the loom, it is attached to the loom only before the loom starts operation, and is removed during the loom operation. Can be used. Therefore, if there are at least two hook frame height adjusting devices of the present invention to be attached to the left and right sides of the hook frame, the height adjustment of the hook frame of the entire loom is performed by repeating the height adjustment operation of the hook frame for each hook frame. Since the work can be performed, the manufacturing cost of the opening device can be reduced.

  Further, the present invention is irrelevant to the reciprocating drive device and the drive transmission mechanism by the opening device, and can be removed and used during the operation of the loom.

  Moreover, according to the present invention, when the lifting means is used after being attached between the fixing portion of the loom and the hook frame, the hook means can be moved up and down by moving the engaging means up and down. Accordingly, since the support height of the collar frame by the drive transmission mechanism can be changed, the height adjustment work of the collar frame can be easily performed.

It may be the upper surface of other than 95. That is, the seat portion 32 is placed in a fixed portion of the loom, and a portion whose height does not change with respect to the upper surface of the frame 95 of the loom.

  A wing nut 36 different from that of the engaging means 2 and another nut 37 are screwed onto the upper end portion of the screw member 31 adjacent to each other in the vertical direction, and the position of the wing nut 36 is similarly fixed. The wing nut 36 serves as the operation unit 33.

  The collar frame height measuring means 4 described below measures the height of a specific part of the collar frame 90 with respect to the reference part, and determines the support height of the collar frame 90 to the operator based on the measurement result. It is something to be made. In the drawing, the upper surface of the heald frame guide 92 is used as the reference location, and the upper surface of the main body block 51 that is flush with the upper surface of the collar frame 90 is used as the specific location of the collar frame 90.

  The saddle frame height measuring means 4 in the figure supports the scale 41 so as to be movable up and down relatively with respect to the main body 5 of the engaging means 2. The operator places the scale 41 on the upper surface of the heald frame guide 92, moves the engaging means 2 in the vertical direction together with the collar frame 90 with respect to the scale 41, and the scale of the scale 41 and the main body at that time The support height of the gutter frame 90 is measured by checking the position indicated by the upper surface of 5.

  The scale 41 is a long and narrow square ruler whose scales are written vertically. In the ruler plate, a long hole 42 penetrating in the front-rear direction is formed in the left and right intermediate portions. The scale 41 is disposed on the front surface of the main body 5 via a pedestal 43, and a washer 45 and a pan head screw 44 are sequentially disposed on the front surface side of the scale 41. By screwing the screw shaft of the pan head screw 44 through the washer 45, the scale 41, and the through holes 43a and 45a of the base 43 and the long hole 42, the scale 41 is screwed into the screw hole 56 on the front surface of the main body 5. Supported by the main body 5. An operator adjusts the screwing depth of the pan head screw 44 with respect to the screw hole 56 of the main body 5 so that a gap is formed between the pedestal 43 and the scale 41, and as a result, on the upper surface of the heald frame guide 92. The engaging means 2 is held so as to be movable in the vertical direction with respect to the placed scale 41.

  The above-described illustrated frame height adjusting device 1 is used in the following procedure. First, the loom is moved and stopped so that the height of the eaves frame 90 becomes a predetermined position. Next, the operator loosens the wing nut 74 of the gripping device 2 in advance before installing the pair of left and right heel frame height adjusting devices 1 on the loom, and sets the distance between the pair of clamp surfaces provided in the gripping device 2 to the side stay 90a. Keep it wider than the thickness. In addition, the operator operates the wing nut 36 of the operation unit 33 in advance to determine the distance between the upper surface of the main body 5 of the gripping device 2 and the bottom surface of the nut 35 with a disc spring, the upper surface of the collar frame 90, and the heald frame guide 92. It should be narrower than the distance from the top surface.

  Then, the operator adjusts the height adjustment devices 1 to the side stays 90a while adjusting the height so that the upper surface of the frame 90 to be adjusted and the upper surface of the main body 5 are flush with each other. The wing nut 74 of the gripping device 2 is brought into contact with the bottom surface of the opening formed by the pair of clamp surfaces of the gripping device 2 to bring the side surface of the side stay 90a into contact with the bottom of the screw member 31 of the lifting means 3. The side stay 90a is gripped by the pair of clamp surfaces.

  Next, the operator relatively rotates the screw member 31 and the female screw portion 54 of the main body portion 5 with the operation portion 33 of the elevating means 3 so that the nut 35 with a disc spring contacts the upper surface of the heald frame guide 92. At this time, the scale 41 falls by its own weight, and its lower end is in contact with the upper surface of the heald frame guide 92.

  Next, the operator loosens the bolts 87c of the left and right heald frame joints 87a that support the eaves frame 90 from below, so that the protruding length of the joint rod 87b with respect to the heald frame joints 87a can be changed. At this time, since the left and right sides of the eaves frame 90 are supported by the pair of eaves frame height adjusting devices 1, 1, the eaves frame 90 does not fall by its own weight. Thereafter, the operator turns the wing nut 36 which is the operation portion 33 of the lifting and lowering means 3 to move the gripping device 2 up and down together with the collar frame 90, and the scale of the scale 41 on the upper surface of the main body 5 serving as a pointer. The heel frame 90 is adjusted to a desired height position while observing the coincident part.

  A specific method of adjusting the height position will be described with reference to FIG. The height adjustment is determined by the height dimension H <b> 1 from the upper surface of the heald frame guide 92 to the upper surface of the collar frame 90. A heald (not shown) is supported on the saddle frame 90, and the height of the saddle frame 90 is adjusted so that the center of the mail in the heald has a desired dimension with respect to the upper surface of the frame 95 of the loom. In that case, in addition to the above-described height dimension H1, a height dimension H2 from the upper surface of the frame 95 to the upper surface of the heald frame guide 92 is also taken into consideration.

  After adjusting the height position, the bolts 87c of the left and right heald frame joints 87a are tightened to fix the protruding length of the joint rod 87b, the heald frame joint 87a and the joint rod 87b are connected, and the support height of the collar frame 90 To fix.

  After that, the wing nut 74 of the gripping device 2 in each heel frame height adjusting device 1 is loosened, the gripping of the heel frame 90 is released, and each heel frame height adjusting device 1 is removed from the loom. This series of operations is repeated as many times as the number of hook frames 90 to be adjusted.

  Next, an example of the collar frame height adjusting device 1 shown in FIGS. 5 and 6 will be described. FIG. 5 is a front view showing a structure for supporting the eaves frame 90 by placing the eaves frame height adjusting device 1 on the heald frame guide 92. 6 (a) is an enlarged front view showing the heel frame height adjusting device 1, and FIG. 6 (b) is an enlarged sectional view taken along line BB of FIG. 6 (a).

  The saddle frame height adjusting device 1 shown in the figure has basically the same configuration and operation as the previous embodiment, but unlike the previous example, the engaging means 2 and the saddle frame 90 are engaged by pin coupling. What is to be combined is used, and the lifting / lowering means 3 is one incorporating the eaves frame height measuring means 4. Therefore, the eaves frame height adjusting device 1 does not have the dedicated eaves frame height measuring means 4.

  The engagement means 2 is an engagement device that engages with the outer side surface of the collar frame 90 in the left-right direction. The engaging device 2 includes a main body portion 5 that is moved up and down by the elevating means 3, and an engaging pin 57 that protrudes from the inner surface in the left-right direction of the main body portion 5 toward the side stay 90 a of the collar frame 90.

The engagement pin 57, more precisely, the engagement hole 59 into which the other of the engagement pins 57 is fitted, is formed on the outward side surface of the side stay 90a. The formation height of the engagement hole 59 is determined so that the upper surface of the collar frame 90 and the upper surface of the main body 5 are flush with each other as in the previous example. The engagement hole 59 may be processed in addition to the existing frame 90, or may be processed in advance in the new frame 90.

  The lifting / lowering means 3 is provided with a collar frame height measuring means 4 extending in the vertical direction at the shaft portion of the screw member 31. The heel frame height measuring means 4 is provided with a scale display surface 46 extending in the vertical direction on the shaft portion of the screw member 31, and the scale display surface 46 is marked with a scale in the vertical direction. In the illustrated example, the collar frame height measuring means 4 forms a scale display surface 46 by cutting a screw thread in the vertical direction for a part of the entire circumferential direction of the stud bolt that is the screw member 31. A linear scale extending at right angles to the axial direction is marked on the scale display surface 46 so as to be vertically marked. Therefore, the cross section of the screw member 31 has a form in which a part of a circle is cut straight in a plan view.

These are fixed to the front piece 23 b with a pan head screw 44, and the scale 41 is interposed between the scale 41 and the nut 26. A play is provided so as to ensure vertical movement.

  The illustrated lifting / lowering means 3 is a combination of the second engaging device 22 and a turnbuckle 38 screwed into the upper bolt 24 of the second engaging device 22 as an operation portion 33. The lower bolt that is screwed to the lower end of 38 is the screw member 31 that extends vertically, and the head of the lower bolt 31 is the seat 32.

  As usual, the turnbuckle 38 has a right-hand thread at one end and a left-hand thread at the other end, so that each male thread portion of the upper bolt 24 and the lower bolt 31 is a reverse thread.

  The illustrated saddle frame height adjusting device 1 is used in consideration of the fact that the first engagement device 21 is a separate body. That is, the operator engages the first engagement device 21 with the left and right sides of the collar frame 90, and then the second engagement device 22, the lifting / lowering means 3, and the collar frame height measuring means 4 are assembled together. These are arranged between the first engagement device 21 and the heald frame guide 92, respectively. At this time, the operator inserts the support member 23 of the second engagement device 22 into the lower portion of the first engagement device 21, and the front and rear of the first engagement device 21 and the second engagement device 22. The direction can be positioned. Thereafter, the operator turns the turnbuckle 38 to support the collar frame 90 by bringing the bottom surface of the lower bolt 31 into contact with the upper surface of the heald frame guide 92. After this, it is the same as other examples.

  The illustrated second engaging device 22 is described as a part of the engaging means 2 in the above description, but may be described as a part of the elevating means 3. In this case, the elevating means 3 includes an internal thread portion of a turnbuckle 38 as a screw member 31 that is screwed into the upper bolt 24 of the second engagement device 22 and extends vertically, and an internal thread portion of the turnbuckle 38. It includes a turnbuckle 38 as an operation portion for rotating the upper bolt 24 of the second engagement device 22 and a lower bolt 31 as a seat portion placed on a fixing portion of the loom.

  The heel frame height adjusting device 1 is not limited to the above-described example. In the first example, the protruding direction of the male screw 71 of the fastening part 7 is perpendicular to the through direction of the through hole 53 of the main body part 5 in the gripping device 2 and perpendicular to the gripping direction. However, the present invention is not limited to this and may be parallel to the gripping direction, or may be parallel to the axial direction of the female screw portion 54 of the main body 5.

  In the second example, the engagement pin 57 is integrated with the main body 5 and the engagement hole 59 is provided in the side stay 90a. However, the present invention is not limited to this, and the engagement pin 57 is integrated with the side stay 90a to be engaged. The hole 59 may be provided in the main body 5 or an engagement hole may be provided in the main body 5 and the side stay 90a, and the engagement pin 57 may be used as a single member.

  In the second example, the gutter frame height measuring means 4 uses the upper surface of the main body 5 that is flush with the upper surface of the gutter frame 90 as a pointer, and the operator reads the value of the scale that matches the gutter frame 90. However, the present invention is not limited to this, and a dedicated pointer may be provided at a location that does not coincide with the upper surface of the collar frame 90. For example, although not shown, the frame frame height measuring means 4 uses a normal stud bolt in which the screw member 31 has threads at both ends of the entire length and has no threads in the middle of the entire length. Is a scale display surface 46, and the main body 5 is moved by a male screw portion 31 a below or above the scale display surface 46, and a dedicated pointer is directed from the main body 5 toward the scale display surface 46 above or below. It may be a projecting part.

  In the last example, the structure in which the first engaging device 21 that is separate from the collar frame 90 is engaged with the collar frame 90 is used. The first engaging device 21 may be integrally provided. In this case, the first engaging device 21 is not included in the collar frame height adjusting device 1, and the engaging means 2 is the second engaging device 22. Consists of only.

  Similarly, in the last example, the combination of the turnbuckle 38 and the lower bolt 31 is configured such that the length of the elevating means 3 is changed. Instead, instead of the lower bolt 31, a rotatable support shaft is used. And a nut member that rotatably supports the upper portion of the support shaft on the lower side instead of the turnbuckle 38, and the upper bolt 24 of the second engagement device 22 is screwed into the female screw on the upper side of the nut member. The upper bolt 24 may be used as the screw member 31. In addition, instead of the upper bolt 24, a simple support shaft that hangs down from the U-shaped support member 23 is provided, and instead of the turnbuckle 38, a nut member that rotatably supports the lower portion of the support shaft on the upper side is provided. The lower bolt 31 may be screwed into the female screw on the lower side of the member. Further, instead of the turnbuckle 38, the upper bolt 24, and the lower bolt 31, a turnbuckle rod provided with male screws of opposite threads at both ends, and a nut member screwed to each male screw may be provided.
