Description

Technical Field

[0001] The present application relates to the field of bobbin seat rails, and in particular to a combined bobbin seat rail. Background Art

[0002] At present, spinning frames are generally equipped with collective doffing devices, which are devices that automatically remove full bobbins and replace them with empty bobbins. During operation, bobbins are generally transported by bobbin holders installed on steel belts. When working, the track transports empty bobbins to the standby position and sends full bobbins to the bobbin transfer box or the winding machine, thereby achieving the purpose of exchanging and recycling full bobbins and empty bobbins.

[0003] The track used to install the bobbin holder in the related art is generally a circular track as a whole, and is spliced ​​by multiple track components. The track generally needs to meet certain load-bearing requirements, and the surface needs to be relatively smooth to facilitate the smooth operation of the bobbin holder. Therefore, the traditional method of making the track component is to first bend the entire steel plate into a U shape, then evenly open holes on the two sides of the U-shaped track, insert the steel plate at the opening, and weld from the outside to the inside until the solder fills the hole, and then grind it.

[0004] With respect to the above-mentioned related technologies, the inventors believe that in the actual track manufacturing process, the manufactured track components have certain defects. First, when welding, hot welding is generally used, which easily causes the steel plate itself to deform. Since the length of a single steel plate on the track is 1.4 meters, the deformation of the steel plate after welding is relatively large, which easily causes the yarn tube seat to be stuck when moving. In order to ensure the flatness of the steel plate after welding, more advanced welding processes and welding equipment are required, which greatly increases the production cost of the track. Second, since the welding between the track body and the side steel plate is called one-piece, if the track part needs to be replaced, it is often necessary to replace a continuous long track as a whole, which brings great inconvenience to inspection and maintenance. In addition, due to the first defect mentioned above, when the entire circular track adopts the existing track assembly, not only is the cost too high, but also unnecessary waste is caused due to the lack of scientific force analysis. Summary of the invention

[0005] In order to solve the problems of greater difficulty in later maintenance and higher manufacturing cost of existing bobbin seat rails, the present application provides a combined bobbin seat rail and a production method thereof.

[0006] The combined bobbin holder track provided in this application adopts the following technical solution:

[0007] A combined bobbin seat track, the track comprises a plurality of track unit assemblies connected end to end, the track unit assemblies comprise a plurality of integral track units and a plurality of assembled track units; the integral track units and the assembled track units both comprise a track base and a track panel; the track base comprises a track bottom plate and two track side plates arranged away from the track bottom plate; the two track panels are arranged oppositely on the two track side plates; at least the middle section of the track adopts the assembled track unit.

[0008] By adopting the above technical solution, the track can be spliced ​​together by multiple track component units, which greatly improves the convenience of track assembly and reduces the difficulty of later maintenance of the track. The integrated track unit can be used for track components in non-load-bearing areas, and the assembled track unit can be used for track components in main load-bearing areas. The setting of the two types of track unit components allows designers to allocate them according to actual needs to achieve a balance between the overall practicality and economy of the track. The assembled track unit is assembled from a track side panel and a track base, and the two are fixedly connected by screws and nuts. On the one hand, it reduces material deformation caused by welding, and on the other hand, it greatly improves the convenience of later maintenance of this type of track unit assembly.

[0009] Preferably, the track base and the track panel of the integrated track unit are formed in one piece, and the track base and the track panel of the assembled track unit are detachably fixedly connected via a connecting structure.

[0010] By adopting the above technical solution, the integrated track unit can be manufactured with materials with relatively low structural strength, such as one-time molding of aluminum alloy profiles, which reduces the manufacturing difficulty and the economic cost required for manufacturing.

[0011] Preferably, a reinforcement plate is connected between the opposite long sides of the track, and the connection between the reinforcement plate and the track is located at the connection between two adjacent track unit assemblies. Both end surfaces of each track unit assembly are treated without protrusions.

[0012] By adopting the above technical solution, the protrusion-free treatment at both ends of the track unit assembly can be achieved by using press-in screws or grinding the protruding parts of the screws. The protrusion-free treatment is mainly to facilitate the installation of auxiliary parts of other tracks such as reinforcement plates, while the screws in the middle section of the track unit assembly can retain the protruding parts. This improves the convenience of assembly on the one hand, and reduces time and economic costs on the other.

[0013] Preferably, the cross-section of the track panel is L-shaped, and the track panel includes a mounting panel and a load-bearing panel which are perpendicular to each other. The mounting panel is in contact with the inward side of the track side plate, and the load-bearing panel is located at the end of the mounting panel away from the track bottom plate. The mounting panel and the track side plate are connected to each other by a screw and nut structure.

[0014] By adopting the above technical solution, the cross-section of the track panel is L-shaped, wherein the mounting panel is used to combine with the track side panel to achieve stable installation of the track panel, and the load-bearing panel is used to realize the load-bearing of the yarn tube seat. The track panel of this structure is easy to install and has a relatively stable structure.

[0015] Preferably, reinforcing ribs are provided between the installation panel and the load-bearing panel, and a wear-resistant layer is provided on the surface of the load-bearing panel.

[0016] By adopting the above technical solution, the setting of reinforcing ribs can further improve the overall structural strength of the track surface and reduce the possibility of deformation of the track surface due to long-term load-bearing during long-term use. The load-bearing surface of the track panel needs to frequently rub against the bobbin seat, and the service life of the load-bearing part can be effectively improved by setting a wear-resistant layer.

[0017] Preferably, the track panel is a hollow structure with an installation space arranged inside, the outlet of the installation space faces the track side plate, and the outlet diameter of the installation space is smaller than the maximum diameter of the installation space, and the track side plate is provided with a connecting hole at a position corresponding to the outlet of the installation space, and the connecting structure is partially arranged in the installation space and passes through the outlet of the track panel and the connecting hole of the track side plate to connect the track panel and the track side; the connecting structure includes a locking nut arranged in the installation space and a locking screw penetrating the track side plate, and the locking screw and the locking nut are threadedly connected.

[0018] By adopting the above technical solution, when installing this kind of track surface, it is necessary to open a number of connection holes at the corresponding positions on the surface of the track side plate, then place the track panel at the corresponding position on the inner side of the track side plate, and align the locking screw with the locking nut and tighten it to achieve the installation of the track panel. When this kind of track panel bears the weight from the bobbin seat, it can distribute the pressure more evenly to the track base itself, so it is less likely to undergo drastic deformation during long-term use. Although the structure is more complicated, it can achieve better load-bearing effect and longer service life.

[0019] Preferably, the connection holes located on the surface of the track side plate are arranged in an array along the length direction of the track side plate, and a plurality of rows of the connection holes are arranged along the height direction of the track side plate.

[0020] By adopting the above technical solution and providing multiple rows of connection holes, the height of the track panel can be adjusted during installation to improve the applicability of the track unit assembly.

[0021] Preferably, the rows of connection holes on the surface of the track side plate are staggered.

[0022] By adopting the above technical solution, the staggered connection holes in each row can improve the overall strength of the track base and reduce the situation where the structural strength of the track base is reduced due to insufficient material in some parts.

[0023] Preferably, the inner surface of the track side plate is provided with a filling sponge, and the filling sponge is located at an end of the track panel away from the track bottom plate.

[0024] By adopting the above technical solution, the filling sponge can effectively fill the gap between the rail side plate and the hosting seat. On the one hand, it can reduce the possibility of severe surface wear of the hosting seat during long-term use. On the other hand, it can also reduce the amount of debris falling between the rail and the hosting seat, thereby reducing the frequency of rail failures.

[0025] The present application provides a method for producing a combined bobbin holder track using the following technical solution:

[0026] A method for producing a combined bobbin seat track comprises the following steps:

[0027] Stress analysis: determine the type of track unit components required for each part according to the load-bearing conditions of each part of the track during actual operation. Parts with lower load-bearing requirements use integrated track units, while parts with higher load-bearing requirements use assembled track units.

[0028] Track unit assembly manufacturing, including manufacturing of integrated track units and assembled track units. After manufacturing, the outer surfaces of both ends of each track unit assembly in the length direction and the inner surfaces of the track side panels are polished;

[0029] Track assembly: place each track unit assembly in the specified position and connect each track unit assembly in sequence, and accurately calibrate and polish the joints of the track unit assemblies and the corners of the track;

[0030] Track test: Place the bobbin holder on the assembled track and apply load for track test. During the test, the load applied to the bobbin holder can be 1-2 times the normal load. After the test, the track part where the bobbin holder is blocked is re-calibrated and polished, and the integrated track unit part with obvious deformation is replaced with an assembled track unit.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The embodiment of the present application discloses a combined bobbin seat track.

[0040] Example 1

[0041] Reference Figure 1-3 The track includes several track unit assemblies connected in the first place, the track unit assemblies include an integrated track unit 3 and an assembled track unit 4, and the track unit assemblies include a track base 1 and a track panel 2. The track base 1 has a U-shaped cross section and includes a horizontal track bottom plate 11 and two vertical track side plates 12. The track panel 2 is arranged on the track side plates 12 and is parallel to the track bottom plate 11. A bobbin holder is placed on the track panel 2. The track base 1 and the track panel 2 of the integrated track unit 3 are integrally formed, and the track base 1 and the track panel 2 of the assembled track unit 4 are detachably fixedly connected through a connecting structure.

[0042] Reference Figure 1-3A reinforcing plate 5 is connected between the long sides of the track. The connection between the reinforcing plate 5 and the track is located at the connection between two adjacent track unit assemblies. Both end surfaces of each track unit assembly are treated with no protrusions. In this embodiment, the no protrusion treatment at both ends of the track unit assembly can be achieved by using press-in screws or grinding the protruding parts of the screws. The no protrusion treatment is mainly to facilitate the installation of auxiliary parts of other tracks such as the reinforcing plate 5, while the screws in the middle section of the track unit assembly can retain the protruding parts, which improves the convenience of assembly on the one hand and reduces time and economic costs on the other.

[0043] Reference Figure 1-3 The track panel 2 has an L-shaped cross section. The track panel 2 includes a mounting panel 41 and a load-bearing panel 42 that are perpendicular to each other. The mounting panel 41 is in contact with the inner side of the track side panel 12. The load-bearing panel 42 is located at the end of the mounting panel 41 away from the track bottom plate 11. The mounting panel 41 and the track side panel 12 are connected to each other through a screw and nut structure. A reinforcing rib 43 is provided between the mounting panel 41 and the load-bearing panel 42. A wear-resistant layer 44 is provided on the surface of the load-bearing panel 42.

[0044] Reference Figure 1-3 The inner surface of the track side plate 12 is provided with a filling sponge 14, and the filling sponge 14 is located at the end of the track panel 2 away from the track bottom plate 11. The filling sponge 14 can effectively fill the gap between the track side plate 12 and the hosting seat, which can reduce the possibility of severe wear on the surface of the hosting seat during long-term use, and can also reduce the amount of debris falling between the track and the hosting seat, thereby reducing the frequency of track failure.

[0045] The implementation principle of Example 1 is as follows: the track can be spliced ​​together by multiple track component units, which greatly improves the convenience of track assembly and reduces the difficulty of later maintenance of the track. The integrated track unit 3 can be used for track components in non-load-bearing areas. The integrated track unit 3 can be made of materials with relatively low structural strength, which reduces the difficulty of manufacturing and reduces the economic cost required for manufacturing. The assembled track unit 4 can be used for track components in the main load-bearing areas. The setting of the two types of track unit components allows the designer to allocate them according to actual needs to achieve a balance between the overall practicality and economy of the track. The assembled track unit 4 is assembled from a track side plate 12 and a track base 1, and the two are fixedly connected by means of screws and nuts when spliced ​​together. On the one hand, it reduces the material deformation caused by welding, and on the other hand, it greatly improves the convenience of later maintenance of this type of track unit assembly.

[0046] The cross section of the track panel 2 is L-shaped, wherein the mounting panel 41 is used to combine with the track side panel 12 to achieve a stable installation of the track panel 2, and the load-bearing panel 42 is used to bear the load of the yarn tube seat. The track panel 2 of this structure is easy to install and has a relatively stable structure.

[0047] Example 2

[0048] Reference Figure 4 The difference between this embodiment and the embodiment is that an installation space 45 with a T-shaped cross-section is formed inside the track panel 2, a locking nut 46 is pre-embedded in the installation space 45, a connecting hole 13 for installing the track panel 2 is opened at a corresponding position of the track side plate 12, a locking screw 47 is passed through the connecting hole 13, the nut of the locking screw 47 is located on the outside of the track side plate 12, and the locking screw 47 and the locking nut 46 cooperate with each other.

[0049] Reference Figure 4 The connection holes 13 on the surface of the track side plate 12 are arranged along the length direction of the track side plate 12, and the connection holes 13 are arranged in multiple rows along the height direction of the track side plate 12, and the connection holes 13 in each row on the surface of the track side plate 12 are staggered. The staggered connection holes 13 in each row can improve the overall strength of the track base 1 and reduce the situation where the structural strength of the track base 1 is reduced due to insufficient material in some parts. By setting multiple rows of connection holes 13, the height of the track panel 2 can be adjusted during installation to improve the applicability of this track unit assembly.

[0050] The implementation principle of Example 2 is as follows: when installing this type of track surface, it is necessary to open a number of connection holes 13 at corresponding positions on the surface of the track side plate 12, then place the track panel 2 at corresponding positions on the inner side of the track side plate 12, and align the locking screw 47 with the locking nut 46 to tighten the track panel 2. When this type of track panel 2 bears the weight from the bobbin seat, it can distribute the pressure more evenly to the track base 1 itself, so that during long-term use, it is less likely to be drastically deformed. Although the structure is more complicated, it can achieve better load-bearing effect and longer service life.

[0051] The embodiment of the present application also discloses a method for producing a combined bobbin seat track.

[0052] The production method of the combined bobbin seat track comprises the following steps:

[0053] Stress analysis, according to the load-bearing and stress-bearing conditions of each part of the track as a whole during actual operation, determines the type of track unit components required to be used for each part, wherein the part with lower load-bearing requirements adopts the integrated track unit 3, and the part with higher load-bearing requirements adopts the assembled track unit 4. In this embodiment, the part where the track is connected to the head and tail of the spinning machine can adopt the integrated track unit 3, and the bobbin placed on the bobbin seat here is generally an empty tube, so the track has a lower load-bearing requirement; the remaining part of the track can adopt the assembled track unit 4, and the bobbin placed on the bobbin seat here is generally a full bobbin or a combination of an empty tube and a full bobbin, and the track has a higher load-bearing requirement.

[0054] The track unit assembly is manufactured by manufacturing the integrated track unit 3 and the assembled track unit 4 respectively. After the manufacturing is completed, the outer surfaces of both ends of each track unit assembly in the length direction and the inner surface of the track side plate 12 are polished. In this embodiment, the integrated track unit 3 is made of aluminum alloy material, which is convenient for batch stamping and can greatly reduce the manufacturing cost; the assembled track unit 4 is made of steel alloy material, which can greatly improve the structural strength of the assembled track unit 4.

[0055] Track assembly: place each track unit assembly in the specified position and connect each track unit assembly in sequence, and accurately calibrate and polish the joints of the track unit assemblies and the corners of the track;

[0056] Track test: Place the bobbin holder on the assembled track and apply a load for track test. During the test, the load applied to the bobbin holder can be 1-2 times the normal load. After the test, the track part where the bobbin holder is blocked is re-calibrated and polished, and the integrated track unit 3 with obvious deformation is replaced with an assembled track unit 4.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
