Description

Frame structure of combing machine

Technical Field

The invention relates to a frame construction of a combing machine.

Background

Generally, a combing machine includes a working unit in which 8 combing heads are arranged. As such a frame structure of the combing machine, for example, there is a frame structure disclosed in patent document 1. The frame structure of the combing machine disclosed in patent document 1 includes: a left side frame and a right side frame configured to sandwich all the combing heads; and rails (beams) erected on the left and right side frames. The nipper shaft, the cylinder shaft, and the detaching roller of the combing head are supported on the upper rail via a bracket fixed to the upper rail.

Patent document 1: japanese laid-open patent publication No. 2012-1844

In recent years, however, a combing machine including a working unit having 12 or 16 combing heads has been proposed. In the frame structure supporting 12 or 16 combing heads, the rail connected between the left side frame and the right side frame is also extended, and transportation is difficult compared to a combing machine including a working unit in which 8 combing heads are arranged.

Disclosure of Invention

The object of the present invention is to provide a frame structure of a combing machine capable of easily transporting the combing machine.

The frame structure of the combing machine for solving the above problems is provided with: a left side frame and a right side frame configured to sandwich all the combing heads; and a plurality of beams which are erected on the left side frame and the right side frame and are juxtaposed in parallel to each other, wherein the combing machine is dividable into: a left side unit having the left side frame and a plurality of beam structure members having one longitudinal end connected to the left side frame and constituting a part of the beam; and a right unit including the right frame and a plurality of beam structural members having one longitudinal end connected to the right frame and constituting a part of the beam, wherein one of the left unit and the right unit includes an intermediate frame connected to the other longitudinal end of the beam structural member of the left unit and the other longitudinal end of the beam structural member of the right unit, and the other of the left unit and the right unit includes a beam support frame supporting the beam structural member.

With this configuration, the combing machine frame is constructed so as to be dividable into the left side unit and the right side unit, whereby the combing machine can be dividable for transportation, and the combing machine can be transported more easily than in the case where the combing machine is transported without being divided. The left-side unit and the right-side unit can maintain the state in which the beam structural members are arranged in parallel with each other via the intermediate frame or the beam support frame. Thus, even if the combing head is supported by the beam structure member of the left side unit or the beam structure member of the right side unit, the beam structure member is not bent, and the combing head can be transported in a state of being arranged in each of the left side unit and the right side unit.

In the frame structure of the combing machine, the combing machine may include a working unit in which 12 combing heads are arranged, 8 combing heads may be arranged in the left side unit, and 4 combing heads may be arranged in the right side unit.

With this configuration, a general frame structure of the combing machine includes a working unit on which 8 combing heads are arranged. By arranging 8 combing heads in the left side unit, the left side unit can be made to have the same frame structure as a normal combing machine. Therefore, by adding the right side unit to the left side unit which is a normal frame structure of the combing machine, it is possible to construct a combing machine including a working section in which 12 combing heads are arranged.

In the frame structure of the combing machine, the combing machine may include a working unit in which 12 combing heads are arranged, and 6 combing heads may be arranged in each of the left side unit and the right side unit.

With this configuration, a general frame structure of the combing machine includes a working unit on which 8 combing heads are arranged. By providing 6 combing heads in each of the left side unit and the right side unit, the dimension of the left side unit in the longitudinal direction and the dimension of the right side unit in the longitudinal direction can be made smaller than in a typical frame structure of a combing machine.

In the frame structure of the combing machine, the shaft support frame for supporting the shafts (the shaft of the lap roller, the cylinder shaft, the detaching roller, and the nipper shaft) of the combing head may be coupled to the beam structure member in the left side unit and the right side unit, and the intermediate frame may include a shaft support portion for supporting the shafts.

With this configuration, the frame structure of the combing machine is constructed by connecting the left side unit and the right side unit, and the shaft support portion can be provided between the left side unit and the right side unit. The shaft support frames provided in the left and right units and the shaft support sections provided in the intermediate frame can support the shaft of the combing head.

According to the present invention, the combing machine can be easily transported.

Detailed Description

Hereinafter, an embodiment in which the frame structure of the combing machine is embodied will be described with reference to fig. 1 to 7. As shown in fig. 1 (a), the combing machine includes a working unit provided with 12 combing heads 11.

As shown in fig. 2, each combing head 11 includes: a pair of lap rollers 12; a nipper device 14 provided with a feed roller 13; a combing cylinder 15 that rotates integrally with the cylinder shaft 15 a; and two pairs of front and

rear detaching rollers

16 and 17, the two pairs of front and rear detaching

rollers

16 and 17 including upper detaching

rollers

16a and 17a and lower detaching

rollers

16b and 17b (the detaching

rollers

16 and 17 are vertically paired, and the paired detaching rollers are two pairs of front and rear detaching rollers). The nipper device 14 has a nipper frame 18, the nipper frame 18 is arranged to be swingable forward and backward above the combing cylinder 15, and the nipper frame 18 includes a lower nipper 19 at the bottom thereof. The nipper frame 18 is provided with a nipper arm 20 rotatably via a support shaft 18a, and an upper nipper 20a is fixed to a distal end of the nipper arm 20. The upper nipper 20a is opened and closed at a predetermined timing in synchronization with the forward and backward movement swing motion of the nipper frame 18, and grips the lap L in cooperation with the lower nipper 19. The top comb 21 is attached to the nipper frame 18 so as to perform a predetermined movement in front of the lower nipper 19 in synchronization with the nipper frame 18.

Behind the combing cylinder 15 and below the nipper frame 18, a nipper shaft 22 is arranged to be able to rotate reciprocally. A first end portion of the nipper driving arm 23 is fixed to the nipper shaft 22 so as to be rotatable integrally with the nipper shaft 22, and a rear end portion of the nipper 18 is rotatably supported via a support shaft 23a at a second end portion of the nipper driving arm 23. The nipper frame 18 is configured such that the distal end portion of the lower nipper 19 swings back and forth so as to approach and separate from the detaching

rollers

16 and 17 by the reciprocating rotation (swinging motion) of the nipper shaft 22.

Next, a description will be given of a frame structure of the combing machine.

As shown in fig. 1 (a), the frame structure of the combing machine includes a left side frame 24 and a right side frame 25 disposed so as to sandwich all the combing heads 11, and 4 beams 26 (see fig. 3) erected on the left side frame 24 and the right side frame 25. In addition, the comber frame configuration is formed by joining the left side unit U1 and the right side unit U2. Further, the left side unit U1 is a unit located on the left side in the case where the combing machine is viewed from the front, and the right side unit U2 is a unit located on the right side in the case where the combing machine is viewed from the front.

First, the left side unit U1 and the right side unit U2 will be explained.

The left side unit U1 includes a left side frame 24, 4 left side frame members 27 as beam structural members connected to the left side frame 24, and an auxiliary frame 36 connected to the left side frame members 27. As shown in fig. 3, the left side frame 24 has an approximately rectangular plate shape. Each left side member 27 has a left flange 27a at one end in the longitudinal direction, and each left side member 27 is coupled by screwing a screw 40 from the left flange 27a to the left side frame 24.

As shown in fig. 1 (a) or 1 (b), each of the left side frame structural members 27 includes a connecting flange 27b at the other end in the longitudinal direction, and the connecting flange 27b can be connected to the middle frame 39 of the right side unit U2. The 4 left side member structural members 27 are juxtaposed in parallel with each other. When the surface of the left side frame 24 connected to the left flange 27a is the side surface 24b, the longitudinal direction of the left side member structural member 27 is orthogonal to the side surface 24b of the left side frame 24.

As shown in fig. 3, the left side unit U1 includes a shaft support frame 37 supported by the upper 2 left side frame members 27. The shaft support frame 37 is fastened to the upper 2 left side frame structural members 27 by fastening means not shown. The number of the shaft support frames 37 is 8 in the longitudinal direction of the left side member structural member 27 at equal intervals. Combing heads 11 are disposed between the shaft support frames 37 adjacent in the longitudinal direction of the left side frame structure member 27, and the left side unit U1 is in a state of including a working section on which 8 combing heads 11 are disposed.

On the front side of the shaft support frame 37, the

lower detaching rollers

16b, 17b among the detaching

rollers

16, 17 as the shafts are supported, and the cylinder shaft 15a is supported below the

lower detaching rollers

16b, 17 b. The nipper shaft 22 is supported on the rear side of the shaft support frame 37, and the shaft 12a of the lap roller 12 is supported above the nipper shaft 22 in the shaft support frame 37. The shaft 12a, cylinder shaft 15a, and nipper shaft 22 of the lap roller 12 are long enough to support the respective members of the 8 combing heads 11 provided in the left side unit U1.

The lengths of the

shafts

12a, 15a, and 22 in the axial direction are almost the same as the length of the left side unit U1 in the longitudinal direction, but the

shafts

12a, 15a, and 22 can be divided at intermediate positions in the axial direction. Thus, the

shafts

12a, 15a, and 22 in the divided state have lengths capable of supporting the 4 combing heads 11. The

shafts

12a, 15a, and 22, which are divided at intermediate positions in the axial direction, are coupled by a coupling, not shown.

As shown in fig. 1 (a) or fig. 5, the left side unit U1 includes first auxiliary frames 36a and second auxiliary frames 36b between the upper 2 left side frame members 27 and the lower 2 left side frame members 27. The first sub frame 36a is coupled to the 8 th shaft support frame 37 counted from the left side frame 24 side. The first sub frame 36a is coupled to a position of the left side member 27 farthest from the left side frame 24, that is, to the shaft support frame 37 closest to the other end of the left side member 27 in the longitudinal direction.

The second sub frame 36b is coupled to the 5 th shaft support frame 37 counted from the left side frame 24 side. The second sub frame 36b is coupled to the shaft support frame 37 at a position close to the middle of the first sub frame 36a and the left side frame 24 in the longitudinal direction of the left side member 27.

Each of the

sub frames

36a, 36b is formed in a two-pronged shape. The upper ends of the

auxiliary frames

36a and 36b are connected to the shaft support frame 37 at the lower surface of the shaft support frame 37, and the lower ends of the two-prong fork are connected to the upper surface of the lower 2 left side beam structural members 27.

The left side unit U1 includes leg portions 38 at the positions connected to the

auxiliary frames

36a and 36b in the lower 2 left side rail structural members 27. The lower end surface 38a of each leg portion 38 is flush with the lower end surface 24a of the left side frame 24. In a state where the left side unit U1 is placed on a horizontal plane by the lower end surface 24a of the left side frame 24 and the lower end surfaces 38a of the leg portions 38, the left side beam structural members 27 are in a horizontally extending state. The 4 left side frame structural members 27 are supported in a state of being maintained parallel to each other by the shaft support frame 37, the

auxiliary frames

36a and 36b, and the leg portions 38. That is, the left side frame structural members 27 are supported while suppressing the displacement in the height direction by the beam support frame F including the shaft support frame 37, the first sub frame 36a, the second sub frame 36b, and the leg portions 38.

Next, the right side unit U2 is explained.

As shown in fig. 1 (a) or fig. 6, the right side unit U2 includes a right side frame 25, 4 right side beam structural members 28 coupled to the right side frame 25, and a middle frame 39 coupled to the right side beam structural members 28.

The right side frame 25 has an approximately rectangular plate shape. Each right side beam structural member 28 has a right flange 28a at one end in the longitudinal direction, and each right side beam structural member 28 is coupled by screwing a screw 40 from the right flange 28a to the right side frame 25.

As shown in fig. 1 (b) or fig. 7, each right side member 28 includes a connecting flange 28b at the other end in the longitudinal direction, and the connecting flange 28b is connected to the intermediate frame 39 by screwing a screw 40 to the intermediate frame 39. The intermediate frame 39 has an approximately rectangular plate shape. The lower end surface 39a of the middle frame 39 is located on the same plane as the lower end surface 25a of the right side frame 25. Each right side beam structural member 28 is erected between the right side frame 25 and the intermediate frame 39, and the right side beam structural member 28 constructs a beam structure. The 4 right side beam structural members 28 are maintained in a state of being juxtaposed in parallel with each other. When the surface of the right side frame 25 connected to the right flange 28a is the side surface 25b, the longitudinal direction of the right side beam structural member 28 is orthogonal to the side surface 25b of the right side frame 25. In a state where the right side unit U2 is placed on a horizontal plane, each right side beam structural member 28 extends horizontally.

The right side unit U2 includes a shaft support frame 37 supported by the upper 2 right side beam structural members 28. The shaft support frame 37 is fastened to the upper 2 right side beam structural members 28 by fastening means not shown. The shaft support frames 37 are provided at 4 equal intervals in the longitudinal direction of the right side frame structural member 28. Combing heads 11 are disposed between the shaft support frames 37 adjacent in the longitudinal direction of the right side frame member 28. The right side unit U2 is in a state of being provided with a working section on which 4 combing heads 11 are arranged.

The intermediate frame 39 has a shaft support portion 39b at the upper portion. The right unit U2 includes the shaft support frames 37 at 4 positions, and also includes the shaft support portions 39b, and the shaft support portions 39b are adjacent to the 4 th shaft support frame 37 counted from the right frame 25 side. In the right unit U2, the 4 th combing head 11 counted from the right side frame 25 side is provided with the shaft support frame 37 on the right side and the shaft support portion 39b of the middle frame 39 on the left side. The

shafts

12a, 15a, and 22 of the right unit U2 have a length in the axial direction that is capable of supporting 4 parts of the combing head 11.

Further, screws 40 are inserted into the coupling flanges 27b of the left side frame members 27 of the left side unit U1, and the screws 40 are screwed into the middle frame 39, thereby coupling the left side unit U1 and the right side unit U2 to construct a frame structure of the combing machine.

As shown in fig. 1 (a), the lower end surface 24a of the left side frame 24, the lower end surface 38a of the leg portion 38, the lower end surface 39a of the middle frame 39, and the lower end surface 25a of the right side frame 25 are located on the same plane. The left side beam structural member 27 is supported in a state of being maintained parallel to each other by a beam support frame F composed of a shaft support frame 37, a first auxiliary frame 36a, a second auxiliary frame 36b, and a leg portion 38, and the right side beam structural member 28 is supported in a state of being maintained parallel to each other by being erected on the right side frame 25 and the intermediate frame 39. Therefore, the left side frame member 27 and the right side frame member 28 which are opposed to each other in the longitudinal direction of the combing machine are located at positions opposed to each other at the same height.

The left side frame structural member 27 and the right side frame structural member 28 facing each other in the longitudinal direction of the combing machine are coupled via an intermediate frame 39 to construct a single beam 26. The beam 26 is erected on the left side frame 24 and the right side frame 25 to construct a beam structure. The beam structure formed by the beam 26 is maintained by the intermediate frame 39 and the beam support frame F formed by the shaft support frame 37, the first auxiliary frame 36a, the second auxiliary frame 36b, and the leg portion 38. In the frame structure of the combing machine, 4 beams 26 are juxtaposed in a parallel state with each other, and each beam 26 extends horizontally in a state where the combing machine is placed on a horizontal plane.

On the upper 2 beams 26, 8 shaft support frames 37 provided to the left side frame 24, 4 shaft support frames 37 provided to the right side frame 25, and a shaft support portion 39b provided to the right side unit U2 are provided in parallel, and 13 portions capable of supporting shafts (the shaft 12a of the lap roller 12, the cylinder shaft 15a, the detaching

rollers

16 and 17, and the nipper shaft 22) are formed. Further, the combing heads 11 are disposed between the shaft support frames 37 adjacent in the longitudinal direction of the combing machine and between the shaft support frames 37 and the shaft support portions 39 b. The

shafts

12a, 15a, and 22 of the left unit U1 and the

shafts

12a, 15a, and 22 of the right unit U2 are coupled to each other by couplings, not shown, respectively, and support the respective members of the combing head 11.

Next, the operation of the frame structure of the combing machine configured as described above will be explained. For example, in the case of carrying the combing machine into a factory, a left side unit U1 provided with 8 combing heads 11 and a right side unit U2 provided with 4 combing heads 11 are manufactured. Then, as shown in fig. 4, the left unit U1 and the right unit U2 are transported independently from each other in a state of being divided into the left unit U1 and the right unit U2, and are loaded into the factory. In the factory where the vehicle is carried in, the coupling flange 27b of each left side beam structural member 27 of the left side unit U1 is coupled to the intermediate frame 39 of the right side unit U2, thereby coupling the left side unit U1 and the right side unit U2. Then, a combing machine was produced in which the left side frame structural member 27 and the right side frame structural member 28 were connected via the intermediate frame 39 to construct the beam 26 and which was provided with the working section in which 12 combing heads 11 were arranged.

For example, when the combing machine is taken out from the factory for repairing the combing machine, the screws 40 are unscrewed from the coupling flanges 27b of the left side frame structural member 27, the left side frame structural member 27 is separated from the middle frame 39, and the combing machine is disassembled into the left side unit U1 and the right side unit U2. At this time, in a state where the combing heads 11 are provided at the left side unit U1 and the right side unit U2, respectively. Further, the left side unit U1 and the right side unit U2 are transported independently and carried into the repair destination.

With the above embodiment, the following effects can be obtained.

(1) The combing machine including the working unit on which the 12 combing heads 11 are arranged can be divided into the left side unit U1 and the right side unit U2. Therefore, the transportation of the combing machine can be implemented by dividing the combing machine into the left side unit U1 and the right side unit U2, thereby being easy to transport compared to the case of transporting the entire combing machine.

(2) The right side unit U2 maintains the state in which the right side beam structural member 28 is connected to the right side frame 25 and the middle frame 39 and the right side beam structural members 28 are arranged in parallel. The left side unit U1 maintains the state in which the left side beam structural member 27 is connected to the beam support frame F composed of the shaft support frame 37, the first sub frame 36a, the second sub frame 36b, and the leg portion 38, and the left side beam structural member 27 is arranged in parallel. Therefore, when the left side unit U1 and the right side unit U2 are coupled, the positional displacement of the left side frame member 27 and the right side frame member 28 in the height direction can be suppressed, and the positional displacement of the 12 combing heads 11 in the vertical direction can be suppressed. In particular, the

separation rollers

16 and 17, the cylinder shaft 15a, the nipper shaft 22, and the lap roller 12 can be prevented from being displaced in the vertical direction.

(3) The right side unit U2 maintains the state in which the right side beam structural member 28 is connected to the right side frame 25 and the middle frame 39 and the right side beam structural members 28 are arranged in parallel. The left side unit U1 maintains the state in which the left side beam structural member 27 is connected to the beam support frame F composed of the shaft support frame 37, the first sub frame 36a, the second sub frame 36b, and the leg portion 38, and the left side beam structural member 27 is arranged in parallel. Thus, even if a plurality of members such as the detaching

rollers

16 and 17, the cylinder shaft 15a, the nipper shaft 22, and the lap roller 12 are provided, the deflection and the positional displacement in height of the left side member structure member 27 and the right side member structure member 28 can be suppressed, and the plurality of members can be provided. The left side unit U1 and the right side unit U2 are transported separately. Therefore, compared to the case where the components are assembled at the carry-in destinations of the left side unit U1 and the right side unit U2, it becomes easy to manufacture the combing machine at the carry-in destinations.

(4) 8 combing heads 11 are provided on the left side unit U1, and the left side unit U1 is the same as a conventional combing machine. Thus, by adopting a configuration in which the right side unit U2 is linked with respect to the left side unit U1 having the same configuration as a general combing machine frame configuration, a combing machine in which the number of combing heads 11 is increased can be easily constructed.

(5) The right side unit U2 can maintain the beam structure of the right side beam structural member 28 by erecting the right side beam structural member 28 on the intermediate frame 39 and the right side frame 25, and the right side unit U2 can eliminate the need for the beam support frame F including the shaft support frame 37, the first auxiliary frame 36a, the second auxiliary frame 36b, and the leg portion 38.

(6) The middle frame 39 of the right unit U2 is integrally provided with a shaft support portion 39 b. Therefore, the combing head 11 can be set by the middle frame 39 used to connect the right side unit U2 and the left side unit U1. The configuration becomes simple as compared with the case where the shaft support frame 37 is provided independently from the intermediate frame 39.

The above embodiment may be modified as follows.

As shown in fig. 8, the left unit U1 may have a structure including a working unit in which 6 combing heads 11 are arranged, and the right unit U2 may have a structure including a working unit in which 6 combing heads 11 are arranged. In this case, the left side unit U1 includes 6 shaft support frames 37. The sub-frame 36 is coupled to a shaft support frame 37 (the 6 th from the left side frame 24) located farthest from the left side frame 24 in the left side beam structural member 27, and is coupled to a shaft support frame 37 (the 4 th from the left side frame 24) located near the middle between the shaft support frame 37 and the left side frame 24 located farthest from each other.

The right side unit U2 includes a shaft support portion 39b integral with the intermediate frame 39 and a shaft support frame 37 connected to the right side beam structural member 28, and includes 7 portions supporting shafts (the shaft 12a of the lap roller 12, the cylinder shaft 15a, the detaching

rollers

16 and 17, and the nipper shaft 22). The right side unit U2 includes an auxiliary frame 36, and the auxiliary frame 36 is connected to the shaft support frame 37 located at the middle in the longitudinal direction of the portion that supports the shaft.

In the case of such a configuration, the dimension in the longitudinal direction of the left unit U1 becomes shorter than in the case of including the working unit in which 8 combing heads 11 are arranged as in the embodiment. This allows the left unit U1 to be carried in even a place where it cannot be carried in the embodiment.

O may be that the intermediate frame 39 is additionally provided with the shaft support frame 37 without the shaft support 39 b.

The combing machine may be provided with a working unit in which 16 combing heads 11 are arranged.

In this case, it is preferable that the combing heads 11 which can be respectively arranged in the left side unit U1 and the right side unit U2 be 8.

When transporting the left side unit U1 and the right side unit U2, the combing head 11 may be detached and the combing head 11 may be relocated to the loading destination.

In the embodiment, it may be that the auxiliary frame 36 and the leg 38 are provided at the right side unit U2. That is, the right side unit U2 may be provided with a beam support frame F including the shaft support frame 37, the sub frame 36, and the leg portion 38.

O may be that the number of combing heads 11 provided to the left side unit U1 is set to 4, and the middle frame 39 is provided to the left side unit U1. In this case, the number of the combing heads 11 arranged in the right side unit U2 is set to 8, and the sub frame 36 and the leg portion 38 are provided in the right side unit U2.

It may be that the number of combing heads 11 arranged in the left side unit U1 and the right side unit U2 is set to an odd number (3 and 9, 5 and 7).

O may be such that the number of combing heads 11 arranged in the left side unit U1 and the right side unit U2 is set to 4, respectively, and another unit capable of arranging 4 combing heads 11 is provided between the left side unit U1 and the right side unit U2. In this other unit, one axial end of a beam structural member constituting part of the beam 26 is connected to the connection frame, and a flange is connected to the other axial end of the beam structural member. In this independent unit, the beam structural member may be supported by the beam support frame F, or the beam support frame F may not be provided.

Further, the coupling flange 27b of the left side unit U1 is coupled to another unit, and the coupling flange of the beam structural member of the other unit is coupled to the middle frame 39 of the right side unit U2. In this way, a frame structure of a combing machine including a working unit on which 12 combing heads 11 are arranged is constructed.
