Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention supports a member in which a warp beam and a warp thereof are inserted, and prepares a machine that is one step of machine preparation. It is related to the cradle.

[Conventional technology]

When mounting the warp beam on the loom and passing the warp thread to the weaving machine side, in consideration of the time reduction of the work leading to the improvement of the operation efficiency of the loom, the warp thread is warped in advance before the warp beam is newly installed. A work procedure for inserting the dropper of the cutting detecting device, the heddle of the heddle frame and the heddle and the reed is generally adopted. As means for achieving this, the applicant of the present application discloses a cradle for preparing a mechanism in Japanese Patent Laid-Open No. 63-243352. This cradle is a warp beam, a warp cutting detection device in which the warp of the beam is inserted, a warp cutting frame inserted into the warp of the same beam, and a warp member such as a heddle frame and a reed in a positional relationship capable of supporting the warp of the warp beam in a shape substantially similar to the shape of the warp discharged in the loom. And a warp pulling mechanism for collectively pulling out the warp beams of the warp beam through a warp member on the support body.

The empty warp beam removed from the loom and the warp threading member through which the warp thread is passed are supported by the support body, and the woven fabric pieces at the tip of the warp thread row passed through the reed are collectively connected to the warp thread drawing mechanism. From this state, the warp yarn is cut between the warp beam and the warp member, and the warp yarn of the full warp beam is connected to the old warp yarn on the warp member side. Then, by operating the warp drawing mechanism, the warp is collectively drawn from the full warp beam until the knot of the warp passes through the reed. As a result, the warp threading, which is one step of machine preparation, is completed, and with this completion, the full warp beam and the warp members through which the warp threads are passed are stored in a state in which the warp threads are supported in the warp discharge shape on the loom. It Therefore, the coordination between the warp threading operation and the storage, which is one step of the machine preparation, is extremely smooth. Moreover, since the warp passing member that supports the warp in a shape substantially similar to the warp delivery shape is close to the mounted state in the loom, there are various advantages such that the mounting and removal by mechanical means can be easily automated.

[Problems to be solved by the device]

When pulling the knot of the old and new warps up to the front side of the reed on the pedestal having various advantages as described above, the warp winding roller forming the warp drawing mechanism is rotated by a handwheel. However, with such a manual turning operation, the insertion resistance between the warp thread, the dropper, the heddle and the reed of the warp cutting detection device, and a large number of warp threads is too large, and the turning operation of the handwheel handle is very heavy. In particular, when the knots of the old and new warps pass through the warp member, they are easily caught, and attention must be paid to the condition of such knots. If the condition of the knot is not good, the winding speed may be reduced or the warp may be vibrated to facilitate the passage through the knot, but this is also difficult when the handwheel is operated.

In addition, the winding operation tends to be uneven in the manual operation,
There is a risk of cutting the warp.

An object of the present invention is to provide a cradle for machine preparation which can prevent warp breakage and facilitate warp threading work.

[Means for solving the problem]

Therefore, in the present invention, the winding roller for winding the warp beam warp supported on the support body, the hand-turning handle for turning the take-up roller, and the hand-turning handle integrated in the turning axis of the hand-turning handle are integrated. Driven clutch gear that can be selectively switched and rotated integrally with the take-up roller, a take-up motor that includes a drive clutch gear that can mesh with and separate from the driven clutch gear, and a meshing connection that meshes with the drive clutch gear. A warp drawing mechanism is constituted by a switching arrangement mechanism for switchingly holding the driven clutch gear between the position and the disengagement position separated from the driving clutch gear.

[Action]

When pulling the knot of the old and new warps up to the front of the reed, the driven clutch gear is switched to the meshing connection position and meshed with the drive clutch gear. In this state, the winding motor is operated and the winding roller rotates. Therefore, there is no unevenness in the winding speed of the warp and there is no risk of cutting the warp. After the completion of threading, the driven clutch gear is switched to the disengaged position and the winding roller is rotated in the direction opposite to the winding direction by slightly rotating the handwheel handle in the direction opposite to the winding direction. Therefore, the new warp thread pulled through the warp member is relaxed, and the warp thread is not stretched due to long-term tension.

Is intervening.

A support bracket 26 is fixed to the upper front end of the pedestal 14a, and a back roller 27 is rotatably supported between the brackets 26.

Support brackets 28 are fixed to the rear surfaces of the upper ends of the left and right columns 14b, and a take-up roller 29 is rotatably supported between the brackets 28 via a roller shaft 29a.
A ratchet wheel 30 is fixed to one end of the roller shaft 29a, and a ratchet 31 is tiltably supported by one of the support brackets 28. The ratchet 31 meshes with the ratchet wheel 30 by its own weight.

The gear sleeve 32 is fitted to the roller shaft 29a,
It is tightened and fixed by bolts 35. Gear sleeve
A driven clutch gear 36 is fitted in the small diameter portion of 32.
The key 37 is fixed to the small diameter part of the gear sleeve 32,
The driven clutch gear 36 is slidable along the key 37 and is not rotatable with respect to the gear sleeve 32.

On the end surface side of the large diameter part of the gear sleeve 32 is a handwheel
38 is attached via bolt 39. The bolt 39 penetrates the long hole 40 on the large diameter portion of the gear sleeve 32, the long hole 36a on the driven clutch gear 36, and the collar 41, and is screwed into the ring plate 42.

The collar 41 includes a large diameter portion 41a, a medium diameter portion 41b and a small diameter portion 41c. The long hole 40 has a diameter smaller than that of the large diameter portion 41a, and
The insertion portion 40a has a diameter larger than the diameter of 1b, and the retaining portion 40b having a width smaller than the diameter of the medium diameter portion 41b and larger than the diameter of the small diameter portion 41c. The middle diameter portion 41b of the collar 41 is the insertion portion 40.
It is passed through a and joined to the back surface of the driven clutch gear 36, and the large diameter portion 41a is sandwiched between the gear sleeve 32 and the handle shaft 38a. The handle shaft 38a, the collar 41, and the ring plate 42 are integrated by the tightening action of the bolt 39, and move integrally with the handwheel 38.

A pressing spring 43 is interposed between the handle shaft 38a and the gear sleeve 32 so as to surround the large diameter portion 41a of the collar 41. The medium diameter portion 41b is the insertion portion 40 of the medium diameter portion 41b and the long hole 40.
The driven clutch gear 36 can be slid with respect to the gear sleeve 32 only when the position a matches the position a. Therefore, when the medium diameter portion 41b is inserted into the insertion portion 40a, the handwheel 38 is separated from the gear sleeve 32 by the spring action of the pressing spring 43 as shown in FIG. When is pushed in the direction of the rotation axis l, the gear sleeve 32 is switched and arranged so as to approach the gear sleeve 32 as shown in FIG. The length of the collar 41 is set so as to have a predetermined distance L between the large diameter portion of the gear sleeve 32 and the driven clutch gear 36, whereby the driven clutch gear 36 is separated from the gear sleeve 32 by a distance L. Only slide displacement is possible. That is, the gear sleeve 32, the key 37, the bolt 39, the collar 41, the ring plate 42, and the pressing spring 43 constitute the switching arrangement mechanism 50.

A variable speed motor 44 is installed immediately below the driven clutch gear 36, and a drive clutch gear 44a is attached to its output shaft. The driven clutch gear 36 is restricted in sliding displacement between a meshing connection position where it meshes with the drive clutch gear 44a and a connection release position where it contacts the large diameter portion of the gear sleeve 32.

When the warp beam warp on the loom is consumed,
For example, a warp cutting detection device in which an empty warp beam on a loom is passed through its warp by a device such as disclosed in Japanese Patent Laid-Open No. 63-99355, and a plurality of heddle frames and reeds are carried to a device preparation room. As shown in FIG. 1, it is transferred onto the mechanism preparation cradle having the above-mentioned structure. The left and right bearings 45a of the empty warp beam 45 are temporarily placed on the mounting recess 15b, and then rolled onto the mounting recess 15c along the guide groove 15a. Due to this rolling arrangement, the braking plate 20 is pressed against the flange portion of the empty warp beam 45 by the action of the pressing spring 25, and the rotation of the empty warp beam 45 is prevented. Then, by hooking the hook 33 on the warp beam shaft 45b, the pressing spring 2
The floating of the empty warp beam 45 due to the action of 5 is prevented, and the empty warp beam 45 does not come off from the mounting recess 15c.

On the other hand, a warp cutting detection device 46 having a large number of droppers (not shown) is installed between the mounting recesses 16a of both the left and right support brackets 16, and a plurality of heald frames 47 are a pair of left and right hanging bars. Suspended and suspended at 18 and further reed 48
Are placed and held on the holding frame 17.

A woven fabric piece W is left on the tip end side of the warp beam T ₁ row of the empty warp beam 45, and the take-up needle 29b on the winding roller 29 stabs the boundary between the woven fabric piece W and the warp thread T ₁ row. Be done. This completes the connection between the winding roller 29 and the woven fabric piece W.

After completion of this connection, as shown in FIG. 3, the driven clutch gear 36 is separated from the driving clutch gear 44a, and when the handwheel 38 is rotated, the rotational displacement is caused by the handle shaft 38a, the bolt 39 and the ring plate 42. Is connected to the roller shaft 29a through the warp yarns, whereby the warp yarn T ₁ is pulled and tensioned. In this tension state, the route of the warp yarn T ₁ from the empty warp beam 45 to the reed 48 is substantially the same as the warp route on the loom.

After the warp tension, a tape is attached to the warp T ₁ row in the width direction, and the attached portion is cut along the tape. Then, the empty warp beam 45 is removed from the machine-preparation cradle, and the full warp beam 49 is mounted instead as shown in FIG. 6, and one warp thread T ₂ and one old warp thread T ₁ of the full warp beam 49 are mounted. Tie with a yarn splicing device. At this time, the front end side of the warp yarn T ₂ is also adhered with a tape, and the adhering portions of both warp yarns T ₁ and T ₂ are sandwiched and supported by an appropriate means to perform a yarn splicing operation.

 When the splicing is complete, the tape is removed.

The warp threading after the completion of the splicing is performed as follows. Third
As shown in the figure, the middle diameter portion 41b of the collar 41 is the insertion portion 4 of the long hole 40.
It has entered 0a. When the handwheel handle 38 is pushed in the direction of the rotation axis l, the middle diameter portion 41b of the collar 41 is disengaged from the insertion portion 40a and the small diameter portion 41c is replaced. Further, the driven clutch gear 36 meshes with the drive clutch gear 44a, and the ring plate 4
The second key groove 42a is disengaged from the key 37. If the handwheel 38 is rotated in this state, the small-diameter portion 41c of the collar 41 becomes the long hole 4
Enter the retaining portion 40b of 0. Therefore, the large diameter portion 41a and the middle diameter portion 41b of the collar 41 sandwich the large diameter portion of the gear sleeve 32, and the collar 41 is prevented from moving in the axial direction with respect to the gear sleeve 32. That is, the handwheel 38, the bolt 39, the ring plate 42, and the driven clutch gear 36 become immovable in the direction of the rotation axis, and the driven clutch gear 36 is maintained in mesh with the drive clutch gear 44a.

In this state, the variable speed motor 44 is operated, and this rotational drive is driven by the drive clutch gear 44a, the driven clutch gear 36, and the key 37.
And, it is transmitted to the roller shaft 29a via the gear sleeve 32, and the winding roller 29 rotates in the warp winding direction.

When operating the variable speed motor 44, the adjusting handle 22 is screwed to the position shown by the chain line in FIG.
The pressure contact state of the brake plate 20 to the flange portion of 49 is loosened.

Due to the operation of the variable speed motor 44, the full warp beam 49 is rotated while receiving the braking action of the braking plate 20, and the knot t between the old and new warp threads T ₁ T ₂ is inserted through the dropper of the warp cutting detection device 46 and the heald frame 47. Pass through the heddle insertion hole and reed 48.

Then, when the knot t passes through the reed 48 as shown in FIG. 7, the warp threading is completed, and the variable speed motor 44 may be stopped.

In such warp threading, the passing resistance of the warp thread when passing through the warp threading member is large, and in particular, the knot t is easily caught in the insertion hole of the warp threading member. This insertion resistance becomes a winding resistance with respect to the winding roller 29, and a load is heavy when the handwheel 38 is rotated. In this embodiment, a variable speed motor is used instead of the human
Since 44 is used, it is very easy to work through. Moreover, since the winding speed of the winding roller 29 by the variable speed motor 44 is constant, if the rotation speed of the variable speed motor 44 is appropriately set, the winding speed can be evenly adjusted at the winding speed corresponding to the warp type. . Therefore, the warp is not cut.

Further, since the variable speed motor 44 is entrusted with winding the warp, the warp can be vibrated to improve the condition of the knot t in the warp member.

Also, the winding speed can be controlled while watching the condition of the knot t by the action of the variable speed motor 44,
A fine threading operation is possible to prevent warp breakage.

Although the variable speed motor 44 is stopped after the knot t has passed through the reed 48, if the knot t is left as it is, the warp thread T ₂ is left in a tensioned state. This condition results in an undesired elongation of the warp yarn T ₂ . Therefore, the engagement between the drive clutch gear 44a and the driven clutch gear 36 is released, and the ratchet wheel 30 is disengaged from the ratchet wheel 30 and the handwheel is turned.
When 38 is rotated slightly to the left, the winding roller 29 is rotated in the direction opposite to the winding direction, and the tension of the warp yarn T ₂ is released. To disengage the meshing connection between the drive clutch gear 44a and the driven clutch gear 36, rotate the handwheel 38 to the left to rotate the middle diameter portion 41 of the collar 41.
It suffices if b is aligned with the insertion portion 40a of the long hole 40. In this state, if the hand is turned and the hand is released from the handle 38, the middle diameter portion 41b of the collar 41
Is inserted into the insertion portion 40a by the spring action of the pressing spring 43. As a result, the driven clutch gear 36 is slid from the meshing connection position in FIG. 4 to the connection release position in FIG. 3, and the meshing connection between the drive clutch gear 44a and the driven clutch gear 36 is released.

[Effect of device]

As described in detail above, in the present invention, the warping operation is performed by the motor, and the tension of the warp thread is released after the completion of the threading operation by the handle, which results from a large insertion resistance when the warp thread is inserted. The winding load is entirely taken up by the motor, the winding speed is uniform, and there is an excellent effect that the threading workability can be improved without causing warp breakage.
