[0006] Problems to be solved by the invention

[0007] However, when the yarn supply package is supplied to the creel by the creel robot, the reaction force when the yarn supply package, which is a heavy object, moves from the creel robot to the creel acts on the creel, which easily causes large swings and tilts on the creel. As a result, the distance between the creel and the creel robot becomes unstable, and there is room for improvement in that it is difficult to supply the yarn supply package by the creel robot. In particular, in recent years, the height of the creel has tended to be higher than before, and the swing and tilt that may occur on the creel have become significant.

[0008] The present invention has been made in view of the above problems, and an object of the present invention is to provide a creel capable of supplying a yarn package with high reliability by a creel robot.

[0009] Means for solving problems

[0010] (1) The creel of the present invention supplies the yarn package to the bobbin through the creel robot, and has the following features:

[0011] a pair of frame bodies, arranged on both sides of a moving path of the creel robot, and supporting the bobbin; and

[0012] A beam mechanism connects the pair of the frame bodies at a position above the creel frame robot.

[0013] At least one of the pair of frame bodies has a frame engaging mechanism along a direction parallel to the moving path of the creel robot, the frame engaging mechanism engaging with an extending member extending from an upper position of the creel robot toward the one frame body.

[0014] According to the creel rack described in (1) above, the parts of the frame body that are above the creel rack robot are connected to each other through a beam mechanism, whereby a pair of frame bodies have high rigidity as a structure. Therefore, even if the reaction force generated when the creel rack robot supplies the yarn supply package to the bobbin of one frame body is applied to the frame body, the swing and tilt of the frame body are reduced by the high rigidity of the frame bodies and the dispersion of the reaction force to the other frame body via the beam mechanism. In addition, since the inclination of the frame body is reduced, the interval between the frame body on one side and the frame body on the other side, and the interval between the creel rack robot and the frame body are respectively maintained fixed. Therefore, the yarn supply package can be supplied to the bobbin with high reliability by the creel rack robot.

[0015] Furthermore, in a highly rigid structure in which the frame bodies are connected to each other by a beam mechanism, the creel robot travels and stops along the frame body in a state in which the extended member is engaged with the frame engaging mechanism. Therefore, even when the number of bobbins arranged in the frame body increases, the creel and the creel robot become taller and are prone to tilting and swinging, the distance between the frame body and the creel robot can be always maintained constant. As a result, the creel robot can supply the yarn package to the bobbin with high reliability.

[0016] (2) In the creel of the present invention, preferably,

[0017] The frame engaging mechanism is a rail having a flange erected in the vertical direction.

[0018] The flange is sandwiched by at least two rollers, and the at least two rollers are provided on the extending member so as to be rotatable around a rotation axis in the up-down direction.

[0019] According to the creel stand described in (2) above, the flange erected in the vertical direction is clamped by a roller, and the roller is provided on the extension member and is arranged to be rotatable around the rotation axis in the vertical direction. Therefore, the distance between the creel stand robot and the frame body is limited to the length of the extension member. Thus, even when the frame body and the creel stand robot are subjected to a reaction force such as toppling, the distance between the creel stand robot and the frame body is maintained fixed.

[0020] (3) In the creel of the present invention, preferably,

[0021] The beam mechanism includes a connecting rod-shaped member connecting the pair of frame bodies to each other.

[0022] The connecting rod-shaped member has a size adjustment mechanism capable of adjusting the length dimension in the axial direction.

[0023] According to the creel stand described in (3) above, during the mounting operation of the beam mechanism to the frame main body, the distance between the pair of frame main bodies can be finely adjusted by the size adjustment mechanism.

[0024] (4) In the creel of the present invention, preferably,

[0025] A plurality of the beam mechanisms are arranged in the longitudinal direction of the frame body.

[0026] According to the creel stand robot of (4) above, a plurality of beam mechanisms are arranged in the longitudinal direction of the frame body, and as a structure in which the frame bodies are connected to each other by the plurality of beam mechanisms, higher rigidity can be obtained, so that the swing and tilt of the frame body are further reduced. As a result, the creel stand robot can supply the yarn package to the bobbin with higher reliability.

[0027] (5) In the creel of the present invention, preferably,

[0028] The beam mechanism has diagonal braces forming a truss structure.

[0029] According to the creel described in (5) above, the beam mechanism has a diagonal brace forming a truss structure, and as a structure in which the frame bodies are connected to each other by the beam mechanism, higher rigidity can be obtained, so that the swing and tilt of the frame bodies are further reduced. As a result, the creel robot can supply the yarn package to the bobbin with higher reliability.

[0030] The creel stand of the present invention may be composed of only the structure described in the creel stand described in (1) above, or may arbitrarily combine the structure described in (1) above with any one of the structures described in (2) to (5) above within the scope that can be integrated. When the structure described in (1) above is combined with any one of the structures described in (2) to (5) above, all or part of the structure described in (1) above may be combined with all or part of the structures described in (2) to (5) above within the scope that can be integrated.

[0039] Hereinafter, a mode for carrying out the present invention will be described with reference to the drawings.

[0040] (Overview of false twist processing system 1)

[0041] Figure 1 The figure is an example of a top view schematically showing the overall configuration of the false twist processing system 1. In the false twist processing system 1, a yarn supply package having yarn wound around a cylindrical paper tube is supplied to the creel 30 by a creel robot 50 that moves on a track 20 extending in a straight line. In addition, when supplying the yarn supply package to the creel 30, the creel robot 50 collects empty paper tubes without yarn wound around them from the creel 30. "Yarn" exemplifies synthetic fibers such as polyester. The "yarn supply package" is a winding package for supplying yarn (synthetic fiber) used in the manufacturing process of a false twist processing machine, etc. The yarn supply package is composed of a cylindrical paper tube in the center portion and the yarn wound around the paper tube, and is wound by inserting a bobbin 31B (refer to Figure 3 The track 20 is equivalent to the "moving path" of the present invention.

[0042] The creel 30 includes a pair of frame bodies 30A and 30B, which are arranged on both sides of the rail 20 and connected by a beam mechanism 40. A raw yarn storage unit 26 is provided at a position adjacent to the frame body 30B in the longitudinal direction. The supply yarn package supplied to the frame bodies 30A and 30B is supplied to the raw yarn storage unit 26 from a conveying device of the overall factory and is temporarily stored in the raw yarn storage unit 26. In addition, the stored supply yarn package is taken out from the raw yarn storage unit 26 by the creel robot 50 and transported to the creel 30.

[0043] The body 10 is provided at a position adjacent to the frame body 30A on the opposite side of the rail 20. In addition, although not shown in the figure, the body 10 is also provided adjacent to the frame body 30B. The body 10 mainly includes, for example, a false twisting machine 12 and a winding machine 14. The yarn unwound from the supply package is supplied from the creel 30 to the false twisting machine 12. The yarn unwound from the supply package is false twisted by the false twisting machine 12. The yarn after false twisting is wound by the winding machine 14.

[0044] The empty paper tubes after all the yarns are unwound from the yarn supply package and no yarns are wound around them are collected from the creel 30 by the creel robot 50. The collected empty paper tubes are transported by the creel robot 50 to, for example, an empty paper tube collection box 22 disposed adjacent to the rack body 30A in the longitudinal direction and collected in the empty paper tube collection box 22.

[0045] (Description of Creel 30)

[0046] Figure 2 FIG. 1 is an example of a perspective view schematically showing the false twisting system 1. Figure 2 In, omitted Figure 1 The false twisting machine 12, the winding machine 14 and the empty paper tube collection box 22 are shown in the figure. In addition, the frame bodies 30A and 30B have the same structure, so the frame body 30A will be mainly described below, and the detailed description of the structure of the frame body 30B will be omitted.

[0047] The frame body 30A is configured to include a plurality of pillars 31 extending in the vertical direction and arranged in two rows along the rail 20, and a plurality of partition plates 32 are supported at predetermined intervals by these pillars 31. A bobbin 31B (see FIG. 1 ) for supporting a paper tube is provided on a pillar 31 close to the rail 20 among the plurality of pillars 31. Figure 3 ).

[0048] Figure 3 1 is a diagram schematically showing the structure of a bobbin 31B provided in a holder body 30A.

[0049] The support column 31 is provided with a rotating cylinder 31A which is rotatable around the support column 31 with the longitudinal direction of the support column 31 as an axial direction. The rotating cylinder 31A is provided with a bobbin 31B and a claw 31C. The bobbin 31B and the claw 31C rotate integrally with the rotation of the rotating cylinder 31A.

[0050] Although the detailed description of the structure of the creel robot 50 is omitted, the creel robot 50 has: an engaging portion 52 that can move in the up-down direction; and a bobbin rotating mechanism 51 that rotates the engaging portion 52. When the creel robot 50 supplies a yarn supply package to the creel 30 and when the creel robot 50 collects empty paper tubes from the creel 30, the creel robot 50 engages the engaging portion 52 with the claw 31C of the creel 30, and in this state, drives the bobbin rotating mechanism 51 to rotate the engaging portion 52. As a result, the claw 31C rotates, and the bobbin 31B also rotates accordingly. By rotating the bobbin 31B toward the creel robot 50 side, the creel robot 50 becomes able to supply the yarn supply package and collect the empty paper tubes.

[0051] When the paper tube is replaced, especially when the yarn supply package is supplied to the frame main body 30A, 30B, the reaction force when the bobbin 31B supports the yarn supply package having weight is applied to the frame main body 30A, 30B. In order to reduce the swing or tilt of the frame main body 30A, 30B caused by the reaction force, the frame main body 30A, 30B is connected by the beam mechanism 40 to form a structure. The beam mechanism 40 connects the frame main body 30A, 30B at a position above the creel robot 50 so as not to hinder the movement of the creel robot 50 moving between the frame main bodies 30A, 30B.

[0052] Figure 4 This is a diagram showing the upper half of the rack bodies 30A, 30B and the creel robot 50 as viewed from the longitudinal direction of the rack bodies 30A, 30B.

[0053] The beam mechanism 40 includes vertical connection members 41A, 41B, a horizontal connection member 42, and diagonal braces 43A, 43B. The vertical connection members 41A, 41B and the horizontal connection member 42 correspond to the "connection rod-shaped member" of the present invention.

[0054] The vertical connection member 41A is in the shape of a long rod and is fixed to the upper part of the frame body 30A in a vertical orientation. The vertical connection member 41A is connected to the support column 31 of the frame body 30A, for example. The vertical connection member 41B is fixed to the upper part of the frame body 30B.

[0055] The transverse connecting member 42 is in the shape of a long bar, and connects the front ends of the longitudinal connecting members 41A and 41B to each other. The transverse connecting member 42 is connected to the longitudinal connecting members 41A and 41B at a substantially right angle. The longitudinal connecting members 41A and 41B and the transverse connecting member 42 may be connected using a clamp or by welding or the like.

[0056] The longitudinal connection members 41A, 41B and the transverse connection member 42 each have a size adjustment mechanism capable of adjusting the length. The size adjustment mechanism may be, for example, a mechanism in which a rod member is inserted into a long tube and the length is adjusted by moving the rod member forward and backward relative to the tube.

[0057] The diagonal braces 43A and 43B are connected obliquely to the longitudinal connection members 41A and 41B and the transverse connection member 42 to form a truss structure. The diagonal braces 43A and 43B can improve the strength of the beam mechanism 40 in a direction perpendicular to the longitudinal direction of the frame bodies 30A and 30B.

[0058] The beam mechanism 40 is provided with a plurality of beam mechanisms in the longitudinal direction of the frame bodies 30A and 30B (see Figure 1 as well as Figure 2 ). Furthermore, the beam mechanism 40 is connected by a connecting member 45 extending in the longitudinal direction. Thus, the beam mechanism 40 can be prevented from falling in the longitudinal direction of the frame bodies 30A and 30B, and the strength of the beam mechanism 40 can be improved.

[0059] In this way, by connecting the separately arranged rack main bodies 30A and 30B by the beam mechanism 40 , the creel stand 30 can be formed into a single structure, and the rigidity of the creel stand 30 can be improved.

[0060] The creel stand 30 includes a long C-shaped steel 35 provided on the upper portion of the stand body 30A. The C-shaped steel 35 corresponds to the "stand engagement mechanism" of the present invention. The C-shaped steel 35 extends in a direction parallel to the rail 20, that is, in the longitudinal direction of the stand body 30A (see Figure 1 as well as Figure 2 ).

[0061] A support plate 36 is provided on the upper part of the frame body 30A in a manner of being mounted on two pillars 31 arranged in a direction perpendicular to the rail 20. In addition, a plurality of support plates 36 are provided at predetermined intervals in the longitudinal direction of the frame body 30A. The C-shaped steel 35 is supported at a position close to the creel robot 50 in the support plate 36 as viewed in the longitudinal direction of the frame body 30A. The C-shaped steel 35 is provided in a posture with an open portion facing upward as viewed in the longitudinal direction thereof. One side surface of the C-shaped steel 35 provided in this manner and extending in the vertical direction corresponds to the "flange" of the present invention.

[0062] The C-shaped steel 35 functions as a guide path for the creel robot 50. Figure 4As shown, the creel robot 50 has an extension member 53A extending from an upper position thereof toward the frame body 30A. The extension member 53A is located at a position above the frame body 30A, and the front end portion extends to the position of the C-shaped steel 35. A pair of rollers 54 are provided at the lower front end of the extension member 53A. The pair of rollers 54 rotate with the vertical direction as the rotation axis. In addition, the pair of rollers 54 rotate in a state of sandwiching one side of the C-shaped steel 35.

[0063] The distance between the creel robot 50 and the rack body 30A is limited to the length of the extension member 53A by clamping one side surface of the C-shaped steel 35 by a pair of rollers 54 of the creel robot 50. Thus, even when the rack body 30A or the creel robot 50 receives a reaction force such as toppling, the distance between the creel robot 50 and the rack body 30A is maintained constant.

[0064] In addition, a support plate 37 is provided on the upper part of the frame body 30B in the same manner as the frame body 30A so as to be mounted on the two pillars 31. In addition, a plurality of support plates 37 are provided at predetermined intervals in the longitudinal direction of the frame body 30B. Long C-shaped steels 38 are provided on the plurality of support plates 37 in a posture in which the open portions thereof face upward when viewed from the longitudinal direction. The C-shaped steels 38 also function as a guide path for the creel robot 50.

[0065] The creel robot 50 has an extension member 53B extending from the upper position thereof toward the frame body 30B. The extension member 53B is located above the frame body 30B, and the front end portion extends to the position of the C-shaped steel 38. A roller 55 is provided at the lower front end of the extension member 53B. The roller 55 rotates with the vertical direction as the rotation axis. The roller 55 is arranged between the two side surfaces of the C-shaped steel 38, and rotates in a state of contact with the two side surfaces.

[0066] (Explanation of the effect)

[0067] As described above, the creel stand 30 of the present embodiment is formed into a structure by connecting the frame bodies 30A and 30B that are separately configured through the beam mechanism 40. Therefore, compared with the case where the frame bodies 30A and 30B are independently configured, high rigidity can be obtained. In addition, for example, even if the reaction force generated when the bobbin 31B of the frame body 30A is supplied with a heavy yarn supply package from the creel stand robot 50 is applied to the frame body 30A, the reaction force is also dispersed to the frame body 30B via the beam mechanism 40, so that swinging and tilting can be reduced. In addition, by connecting the frame bodies 30A and 30B that are separately configured through the beam mechanism 40, the frame bodies 30A and 30B can be prevented from falling down. In addition, by connecting one side of the frame bodies 30A and 30B to the wall or ceiling of the factory, swinging, tilting or falling can be further suppressed. Such an effect is more significant as the height of the frame bodies 30A and 30B becomes higher.

[0068] Furthermore, by reducing the inclination of the frame bodies 30A, 30B, the interval between the frame bodies 30A, 30B and the creel robot 50 can be maintained at a constant distance, so that the creel robot 50 can supply the yarn supply package to the frame bodies 30A, 30B with high reliability.

[0069] Furthermore, since a plurality of beam mechanisms 40 are provided in the longitudinal direction of the frame bodies 30A and 30B, the swing and tilt of the frame bodies 30A and 30B can be further reduced. Thus, the creel robot 50 can supply the yarn supply package to the frame bodies 30A and 30B with high reliability.

[0070] Furthermore, since the lengths of the longitudinal connecting members 41A, 41B and the transverse connecting members 42 of the beam mechanism 40 are adjustable, the distance between the frame bodies 30A, 30B can be adjusted when the beam mechanism 40 is mounted on the frame bodies 30A, 30B. Furthermore, by making it possible to adjust the lengths of the longitudinal connecting members 41A, 41B, for example, the transverse connecting members 42 can be brought into close contact with the beams or ceiling of the factory, thereby preventing the frame bodies 30A, 30B from swinging or tipping over.

[0071] (Variation Example)

[0072] The above is an explanation of the embodiment of the present invention, but the present invention is not limited to the above embodiment, and various changes can be made as long as they are recorded within the scope of the patent claim. For example, in the above embodiment, the beam mechanism 40 is composed of multiple components, but it can also be composed of one component. In addition, the support 31 can be lengthened, and the upper part of the support 31 can be used as a longitudinal connecting component 41A. In addition, as a size adjustment mechanism of the beam mechanism 40, a plurality of small pieces of rod components can be connected to form a long rod component, and the length can be adjusted by adjusting the number of small pieces of rod components. Furthermore, if the movement of the creel stand robot 50 is not hindered, the longitudinal connecting components 41A and 41B can be used instead, and the frame bodies 30A and 30B can be connected only by the transverse connecting component 42.

[0073] Furthermore, in the above embodiment, the beam mechanism 40 connects the frame bodies 30A and 30B in a direction perpendicular to the longitudinal directions of the frame bodies 30A and 30B, but the beam mechanism 40 may connect the frame bodies 30A and 30B in a direction obliquely intersecting the longitudinal directions, for example.

[0074] Furthermore, a C-shaped steel 35 as a frame engaging mechanism is provided at the upper part of the frame body 30A, and one side of the C-shaped steel is clamped by a pair of rollers 54 provided at the lower part of the front end of the extension component 53A, but it is not limited to this. For example, a C-shaped steel may be provided near the center of the frame body 30A in the up-down direction with the open portion facing the creel robot 50 side, and a component extending from the front end of the extension component 53A toward the vertical downward direction to the C-shaped steel is provided, and the C-shaped steel is clamped by a pair of rollers. Even in this case, the interval between the frame body 30A and the creel robot 50 can be maintained at a fixed distance. In addition, a frame engaging mechanism may be provided on each of the frame bodies 30A and 30B.

[0075] Furthermore, in the above-described embodiment, the pair of rollers 54 provided at the lower portion of the front end of the extension member 53A can be rotated in a state where one side of the C-shaped steel 35 is sandwiched therebetween, but in addition thereto, the load of the creel robot 50 can be applied to the web of the C-shaped steel 35. For example, a roller is provided between the roller 54 on the side of the pair of rollers 54 that faces the web of the C-shaped steel and the web, and if the roller 54 and the web can slide, the load of the creel robot 50 can be applied to the web of the C-shaped steel 35. If the load of the creel robot 50 can be applied to the web of the C-shaped steel 35, the creel robot 50 can lean against the frame body 30A, and the frame body 30A can be made more stable by the weight of the creel robot 50. Furthermore, by stabilizing the frame body 30A, the frame body 30B connected to the frame body 30A via the beam mechanism 40 can also be stabilized.

[0076] In addition, in the above-mentioned embodiment, the extension parts 53A and 53B extending from the upper position of the creel robot 50 toward both sides of the pair of frame bodies 30A and 30B are provided, but the present invention is not limited thereto. For example, the extension part (53A or 53B) extending from the upper position of the creel robot 50 toward only one of the pair of frame bodies 30A and 30B may be provided. In this case, a C-shaped steel (35 or 38) may be provided on the upper part of the frame body (30A or 30B) on the side having the extension part, and a pair of rollers 54 provided at the lower part of the front end of the extension part may be rotated while sandwiching one side of the C-shaped steel (35 or 38).

[0077] In the above embodiment, the pair of rollers 54 can rotate while sandwiching one side of the C-shaped steel 35. However, if it is a component (such as L-shaped steel) having a flange that can be sandwiched by the pair of rollers 54, it is not limited to C-shaped steel.
