Description
- 1. Field of the Invention
- The present invention relates to an apparatus and a method for carrying and storing weft ends produced due to weft insertion in a fluid jet loom in a storage section.
- 2. Description of Prior Art
- In a fluid jet loom such as a water jet loom, the weft is inserted into a warp shedding or opening, then beaten, and thereafter, the front end portion is cut away from the textile by a cutter. Therefore, a fluid jet loom generally has an apparatus for recovering the weft ends cut away from the textile.
- One of such weft end recovering apparatus carries the weft ends cut away from the textile by way of a carrier device using a water flow, flows the weft ends downward into a recovery vessel from above together with the water and recovers the weft ends. (Japanese Patent Appln. Public Disclosure (KOKAI) No. 10-195739).
- In this conventional weft end recovery apparatus, the weft ends naturally drop together with water from a discharge section of the carrier device into the recovery vessel, are piled up inside the recovery vessel to be gradually deposited. The recovery vessel separates the weft ends and the water by a filter disposed therein. The separated weft ends are recovered by an operator from the recovery vessel at a suitable time, and the water is recovered into a proper water tank to be recycled for carrying or the like of the weft ends.
- In the weft end recovery apparatus such as above, the weft ends are gradually deposited to exceed a height level of the recovery vessel to finally block the discharge section of the carrier device, thereby preventing discharge of the water flow and the weft ends and carrying of the weft ends.
- Also, in the conventional weft end recovery apparatus, a high heap of the deposited weft ends tend to be collapsed and scattered out of the recovery vessel, and, every time it happens, a work to wipe the water and recover the scattered weft ends is required. Further, the scattered weft ends are dirtied with oil and dust around the recovery apparatus and such dirt prevents recycling of the recovered weft ends.
- In view of the above, the weft end recovery apparatus requires a work to frequently break the deposited weft-end pile to flatten and hands to do so.
- An object of the present invention lies in storing the weft ends as much as possible and reducing the recovery work.
- A method of storing weft ends of a fluid jet loom according to the present invention is to carry by a water flow the weft ends formed due to weft insertion to discharge together with the water flow from a discharge section to a storage section to store them as well as to move the discharge section during discharging.
- An apparatus for storing weft ends of a fluid jet loom according to the present invention comprises carrying and storing device for carrying by a water flow weft ends formed with weft insertion, discharging them together with the water flow from a discharge section to a storage section to store, and moving device for moving the discharge section during discharging.
- The discharge section can be moved by reciprocal linear motion, oscillation, rotation and the like. It is also possible to preinstall a plurality of discharge sections, operate a switching device, a switching valve and the like, switch to an actually discharging discharge section, thereby to move the discharge section.
- When the discharge section is moved, the position for the water and the weft ends to reach in the storage section changes, so that the position for the weft ends to pile up inside the storage section changes to prevent them from piling up at one place. As a result, without requiring hands, a large quantity of weft ends can be stored in the storage section, thereby reducing the frequency of recovery works.
- The storage section may be moved while the discharge section is discharging. Thereby, due to the movement of the storage section, the position where the water and the weft ends reach inside the storage section can be variously changed.
- Another method of storing the weft ends of the fluid jet loom according to the present invention carries by a water flow the weft ends formed due to weft insertion from the discharge section to the storage section together with the water flow to store them and changes the water flow during discharging.
- Still another apparatus for storing weft ends of the fluid jet loom according to the present invention comprises carrying and storing device for carrying by the water flow the weft ends formed due to weft insertion and discharging them from the discharge section to the storage section together with the water flow to store, and device for changing the water flow while discharging.
- In still another method and apparatus for storing weft ends, it is possible to change the direction of the water flow by oscillating the outlet in the discharge section, or to change the opening degree of a flow regulating valve for carrier water or the pressure or the like of the carrier water to change the quantity of the carrier water, thereby changing the discharge speed (impulse) of the water flow.
- In the other method and apparatus for storing weft ends, too, when the water flow changes, the position for the water and the weft ends to reach inside the storage section changes, so that they are prevented from piling up at one place. As a result, without requiring hands, a large quantity of the weft ends can be stored in the storage section, thereby reducing the recovery work.

- FIG. 5 is a view showing a fourth embodiment of the apparatus for storing weft ends according to the present invention.
- Referring to FIGS. 1 and 2, the
apparatus 10 for storing weft ends is applied to a water jet loom together with aweft end processor 12 for processing the weft front ends. - The water jet loom inserts the weft (not shown) from a weft insert nozzle (not shown) into a shedding of the
warp 14 by pressure water, restrains/retains by means of theweft end processor 12 the front ends of the inserted weft, and in that state, beats the weft against the cloth fell with areed 16 to form atextile 18. The front ends of the beaten weft are cut away from thetextile 18 by a cutter (not shown), thus forming the weft ends. - The
weft end processor 12 includes a block-shapedweft catching bracket 20 for catching up the front ends of the weft. Thisweft catching bracket 20 receives the front ends of the weft to be beaten into aslit 22, and exhausts and passes the pressure water from anexhaust channel 24 through the back of theslit 22 into adischarge channel 26. Thereby, the front end portion of the weft is brought into contact with the pressure water at the back of theslit 22, dragged by thedischarge channel 26, restrained and retained. - The
slit 22 has a horizontal U-like shape so as to receive the weft to be beaten from the upstream side in the moving direction of thewarp 14. The weft is received into theslit 22 such that the front end portion penetrates theweft catching bracket 20 in the thickness direction. Thedischarge channel 26 is formed by apipe 28 such that the upper end portion is inserted into theweft catching bracket 20 from downward to the back of theslit 22. - The pressure water is fed to the
exhaust channel 24 from awater storage tank 30 by apump 32 through apipe discharge channel 26 is recovered into theapparatus 10 for storing weft end together with the cut-away weft ends, returned from theapparatus 10 for storing weft ends to thewater storage tank 30 to be reused as the pressure water. - The liquid surface inside the
water storage tank 30 is sensed by awater surface sensor 36, and when the liquid surface is on or below a predetermined level, asolenoid valve 38 is opened to replenish the water in a water holding tank (not shown) from aninlet 40, thereby maintaining at a level within a predetermined allowable range. - In the
apparatus 10 for storing weft ends, carrying and storing means is constituted by apipe 28, aflexible hose 42 connected to the lower end of apipe 28 to form a discharge section, and astorage tank 44 opening upward to form a storing section so as to receive the water and the weft ends discharged from thehose 42, and moving means for moving the discharge section by means of ahose moving mechanism 52 is formed, and further, the storage section is moved by a storagetank moving mechanism 46. - The
hose 42 forming the discharge section forms a weft end carrying path or the exhaust channel together with thepipe 28. Thehose 42 is assembled at its upper end portion into aframe 50 of the loom together with the lower end portion of thepipe 28 by afixture 48. In place of including thehose 42 and anotherpipe 28, with the upper end portion of thehose 42 inserted into theweft catching bracket 20, the upstream side of its inner space may be used as thedischarge channel 26. - The
hose 42 is attached at its lower end portion to thehose moving mechanism 52. Thehose moving mechanism 52 is assembled into theframe 50 of the loom with apivot pin 56 so as to oscillate acam lever 54 within a horizontal plane and rotates aneccentric cam 58 about a perpendicular line by anelectric motor 60 to oscillate thecam lever 54 within the horizontal plane. Thecam lever 54 is always in contact with the outer periphery of theeccentric cam 58 by aspring 61. Theelectric motor 60 is supported on theframe 50 of the loom by amotor bracket 62. - The lower end portion of the
hose 42 is assembled into the other end portion of thecam lever 54 with afixture 63 so as to make the weft ends flow with the water into thestorage tank 44 from above. Therefore, an outlet. 96 formed at the lower end of thehose 42 is moved relative to thestorage tank 44 above thestorage tank 44 with the oscillation of thecam lever 54. However, the range of oscillation of thecam lever 54 is limited to a range for the water and the weft ends discharged from thehose 42 not to scatter out of thestorage tank 44. - The
storage tank 44 has a circular bottom wall and a peripheral wall vertical to the bottom wall, and a plurality ofholes 64, which permit the water to pass but prevent the weft ends from passing, respectively on the peripheral wall and the bottom wall. Therefore, thestorage tank 44 acts as a storage portion having a function of a filter receiving the weft ends from thehose 42 together with the water and separating the weft ends and the water. - The storage
tank moving mechanism 46 has acircular turntable 68 mounted on asupport base 66 through one ormore bearings 70 so as to rotate about a perpendicular line, acase 72 disposed on theturntable 68, and thestorage tank 44 disposed on thecase 72. Thesupport base 66 is installed on afloor 74. - A ring-shaped
gear 76 is assembled into the outer periphery of thecase 72. Thegear 76 is an external-tooth gear, which is engaged with agear 80 which is rotated by amotor 78. Themotor 78 is assembled into thefloor 74 by means of abracket 82. Therefore, when theturntable 68 is rotated by themotor 78, thecase 72 and thestorage tank 44 are rotated about the perpendicular axis. - The
case 72 has aspace 84 for accommodating thestorage tank 44 as well as a plurality ofholes 86 on the bottom wall for passing the water flowing out of thestorage tank 44. Thespace 84 has a circular bottom portion a little larger than the bottom wall of thestorage tank 44 so as to facilitate attachment and detachment of thestorage tank 44 in recovering the weft ends and to facilitate flowing of the water from thestorage tank 44, and is open upward. - The water having passed the
holes 86 of thecase 72 is collected by adent 88 formed in theturntable 68 and opening upward, and flows into thewater storage tank 30 through ahole 92 of thesupport base 66 and achannel 94. - In weaving, the pressure water is always exhausted from the
exhaust channel 24 into thedischarge channel 26. This carries the weft ends together with the exhausted water inside thepipe 26 and thehose 42 to be discharged together with the water from theoutlet 96 at the lower end of thehose 42 into thestorage tank 44. - While weaving, the
motors outlet 96 of thehose 42 is oscillated by thehose moving mechanism 52 to be slowly displaced relative to thestorage tank 44, and thestorage tank 44 is rotated by the storagetank moving mechanism 46 to be slowly displaced relative to theoutlet 96 of thehose 42. - When the
storage tank 44 and theoutlet 96 are displaced together as mentioned above, the position for the water and the weft ends to reach inside thestorage tank 44 variously changes, so that the position for the weft ends pile up inside thestorage tank 44 variously changes, thereby preventing the weft ends from piling up at one place, so that the weft ends are evenly stored in thestorage tank 44. As a result, without requiring hands, a large quantity of weft ends can be stored in thestorage tank 44, thereby reducing the frequency of the recovery works. - The quantity of the weft ends stored inside the
storage tank 44 is detected as the volume of the weft ends, and the height position of the weft ends inside thestorage tank 44 can be detected by aweft end sensor 98 such as a photoelectric sensor and an ultrasound wave sensor. However, the quantity of the stored weft ends can be detected by detecting the weight of the weft ends inside thestorage tank 44 by means of a weight sensor such as a strain gauge. - An output signal of the
weft end sensor 98 is fed to a weft end processing controller not shown, where it is used as a signal to inform by means of a display lamp or the like that a predetermined quantity of the weft ends are stored in thestorage tank 44 and that the weft ends inside thestorage tank 44 are to be recovered. Consequently, an operator can, receiving such information by the display lamp or the like, recover a sufficient quantity of the weft ends from thestorage tank 44 before the weft ends overflow. - Since the
apparatus 10 for storing weft ends moves theoutlet 96 of thehose 42 together with thestorage tank 44 in the above embodiment, the weft ends can be evenly stored in thestorage tank 44 by variously changing the position for the water and the weft ends to reach inside thestorage tank 44. - However, it is possible to move only the
outlet 96 of thehose 42. - Referring to FIG. 3, an the
apparatus 100 for storing weft ends uses afluid pressure cylinder 104 as a drive source of ahose moving mechanism 102. Thefluid pressure cylinder 104 is pivotally assembled into theframe 50 by a horizontally extendingpivot pin 106. - The
fluid pressure cylinder 104 has the lower end portion of thehose 42 attached to a piston rod by afixture 108. Due to this, when the piston rod of thefluid pressure cylinder 104 is extended or contracted, an outlet at the lower end of thehose 42 is displaced within a vertical plane, and the direction of the water flow discharged from thehose 42 is changed. - Therefore, since the position for the weft ends pile up inside the
storage tank 44 is changed by theapparatus 100 for storing weft ends, the weft ends are prevented from piling up at one place and are stored evenly in thestorage tank 44. As a result, without requiring hands, a large quantity of the weft ends can be stored in thestorage tank 44, thereby reducing the frequency of the recovery works. - Referring to FIG. 4, an
apparatus 120 for storing weft ends is provided, in place of a hose moving mechanism, with a waterflow selection mechanism 122 for changing the water flow discharged toward thestorage tank 44. The waterflow selection mechanism 122 uses analuminum pipe 124 in place of a flexible hose and has thepipe 124 assembled into theframe 50 together with thepipe 28 by means of afixture 126. - The front end of the
pipe 124 is connected to awater flow divider 128 for dividing the water flow being discharged. Thewater flow divider 128 has a plurality ofoutlets 130 for discharging the weft ends together with the water and disposes anelectromagnetic valve 132 at eachoutlet 130. Theelectromagnetic valve 132 is selectively opened or closed by a controller. - In the
apparatus 120 for storing weft ends, while weaving, theelectromagnetic valve 132 to be opened is selectively changed. Since this moves the actual outlet and changes the position for the weft ends to pile up inside thestorage tank 44, the weft ends are prevented from piling up at one place inside thestorage tank 44, so that the weft ends are evenly stored. As a result, without requiring hands, a large quantity of the weft ends can be stored in thestorage tank 44, thereby reducing the frequency of the recovery works. - Referring to FIG. 5, an
apparatus 140 for storing weft ends is provided, in place of a hose moving mechanism, with a waterflow selection mechanism 142 for changing the quantity and direction of the water flow discharged toward thestorage tank 44. The waterflow selection mechanism 142 uses analuminum pipe 144 in place of a flexible hose and assembles thepipe 144 into theframe 50 together with thepipe 28 by means of afixture 146. - The front end of the
pipe 144 is connected to an electromagnetic flow rate adjusting valve 148 for dividing the water flow being discharged and for adjusting the flow rate. The electromagnetic flow rate adjusting valve 148 is provided with a plurality ofoutlets 150 for discharging the weft ends together with the water. - In the
apparatus 140 for storing weft ends, while weaving, the degree of opening of eachoutlet 150 is continuously or intermittently changed by the electromagnetic flow rate adjusting valve 148. Due to this, the flow velocity and the quantity of the water discharged from eachoutlet 150 are changed to further change the direction as well as the flow velocity (impulse of water). Since due to the change in water flow the quantity of the weft ends to be discharged and the direction are also changed, the position for the weft ends to pile up inside thestorage tank 44 is changed. As a result, the weft ends, prevented from piling up at one place inside thestorage tank 44, are stored evenly in thestorage tank 44, so that, without requiring hands, a large quantity of weft-ends can be stored in thestorage tank 44, thereby reducing the recovery works. - Also in the embodiments as shown in FIGS. 4 and 5, it is possible to rotate the
case 72 by the motor and move thestorage tank 44. - The present invention can be variously modified without being limited by the above embodiments and without deviating from its purport.
