In a fluid jet loom such as a water jet loom, a weft thread is inserted into the inclined opening, followed by a body stroke, and then the tip of the weft thread is separated from the fabric by a cutter. For this reason, fluid jet looms are generally equipped with a device for recovering the weft end separated from the fabric.

One such weft-stage recovery device is one in which the weft ends separated from the fabric are conveyed by a conveying device using a water flow, and recovered by flowing down with the water from the upper portion of the recovery container. -195739).

In this conventional weft end recovery device, the weft end naturally falls into the recovery container at the discharge portion of the conveying device along with the water flow, and accumulates in the recovery container, and gradually accumulates. The recovery container separates the weft end and the water by a filter disposed therein. The separated weft division is recovered by the operator in a recovery container at an appropriate time, and water is recovered in an appropriate water tank and used again for conveying the weft division.

In the above weft-stage recovery device, the weft-stage is deposited beyond the height level of the recovery container, and as a result, the discharge part of the conveying device is blocked, thereby preventing the flow of water and the weft-stage, thereby preventing the transfer of the weft-stage. do.

In addition, in the conventional weft-stage recovery apparatus, the acid of the highly piled weft-stage collapses and it scatters out of a collection container, and it is necessary to perform the operation | work which wash | cleans water and collects the scattered wefts | edges every time. . Furthermore, the scattered weft ends are polluted by oil or dust around the recovery device, and such contamination prevents reuse of the recovered weft ends.

Best Mode for Carrying Out the Invention

1 and 2, the weft end receiving device 10 is applied to a water jet loom together with the weft end processing device 12 for processing the tip of the weft yarn.

The water jet loom inserts the weft yarn (not shown) into the inclined 14 opening from the weft insertion nozzle (not shown) by the pressure water, and the tip of the inserted weft yarn is constrained by the weft end treatment device 12. • Hold it, and body weave before weaving the weft by the body 16 to form the fabric 18. The tip of the body shredded weft is separated from the fabric 18 by a cutter (not shown). As a result, the weft end is formed.

The weft end processing apparatus 12 includes a weft trapping block 20 on a block for capturing the tip end of the weft thread. The weft catching bracket 20 receives the tip of the weft threaded by the body into the slit 22 and discharges the pressure water from the discharge channel 24 through the inside of the slit 22 to the discharge channel 26. . As a result, the tip portion of the weft thread is brought into contact with the pressure water from the inside of the slit 22 and drawn into the discharge water passage 26, and is held and restrained.

The slit 22 has a transverse U-shape so as to receive the weft thread to be seamed on the upstream side of the inclination 14. The weft thread is taken in by the slit 22 in the state which the tip part penetrated the weft trapping bracket 20 in the thickness direction. The discharge channel 24 is composed of a pipe 28 whose upper end portion is fitted from the bottom to the inside of the slit 22 by the weft trapping bracket 20.

The pressure water is supplied from the reservoir 30 to the discharge water passage 24 by the pump 32 via the pipes 34 and 34. The pressure water discharged to the discharge channel 26 is recovered to the weft end receiving device 10 together with the cut weft end, and returned to the reservoir 30 in the weft end receiving device 10 to be used again as the pressure water.

The water surface in the reservoir 30 is sensed by the sleep sensor 36, when the solenoid valve 38 is opened and the water of the replenishment water tank (not shown) is replenished from the water supply port 40 when it is below a predetermined level, It is maintained at a level within a predetermined allowable range.

The gastric receptacle 10 is open upward to receive the pipe 28, a plastic hose 42 connected to the lower end of the pipe 28 to form a discharge portion, and water and gastric discharged from the hose 42. It consists of the conveyance accommodating means comprised of the accommodating tank 44 which forms a accommodating part, and the moving means which moves a discharge part by the hose moving mechanism 52, and the accommodating part is moved by the accommodating tank moving mechanism 46 further.

The hose 42 forming the discharge portion, together with the pipe 28, forms the transfer path of the weft end, that is, the discharge water passage. The hose 42 is attached to the frame 50 of the loom by the assembling tool 48 together with the lower end of the pipe 28 at the upper end thereof. Instead of having a pipe 28 separate from the hose 42, the upper end of the hose 42 may be fitted to the weft trapping block 20, and an upstream side of the inner space may be used as the discharge water passage 24.

The lower end of the hose 42 is attached to the hose movement mechanism 52. The hose movement mechanism 52 is provided by the spindle pin 56 on the frame 50 of the loom so that the cam lever 54 can swing in the horizontal plane, and the eccentric cam 58 is provided. Is rotated around the vertical line by the electric motor 60 to rock the cam lever 54 in the horizontal plane. The cam lever 54 is always in contact with the outer circumferential surface of the eccentric cam 58 by the spring 61. The electric motor 60 is supported by the frame 50 of the loom by the motor bracket 62.

The lower end of the hose 42 is provided by the assembling tool 63 at the other end of the cam lever 54 so that the upper end of the hose 42 flows out from the upper side together with the water to the storage tank 44. For this reason, the discharge port 96 formed in the lower end of the hose 42 is moved with respect to the storage tank 44 above the storage tank 44 according to the rocking motion of the cam lever 54. As shown in FIG. However, the swing range of the cam lever 54 is limited to the range in which the water and the weft end flowing out from the hose 42 do not scatter out of the storage tank 44.

The storage tank 44 has a circular bottom surface and a circumferential wall perpendicular to the bottom surface, and also includes a plurality of holes 64 for allowing passage of water but preventing passage of the weft end. In each of them. Therefore, the receiving tank 44 acts as a receiving part having a function of a filter which receives the weft end together with water from the hose 42 and separates them.

The holding tank moving mechanism 46 is mounted on the support base 66 with one or more shafts 70 interposed therebetween so that the disk-shaped rotary table 68 can rotate around the vertical line, and the case is placed on the rotary table 68. 72 is arrange | positioned, and the accommodating tank 44 is arrange | positioned at the case 72. As shown in FIG. The support base 66 is attached to the bottom 74.

A ring-shaped cogwheel 76 is provided around the case 72. The cogwheel 76 is an outer cogwheel and meshes with the cogwheel 80 rotated by the electric motor 78. The electric motor 78 is attached to the bottom 74 by the bracket 82. For this reason, when the rotating table 68 is rotated by the electric motor 78, the case 72 and the storage tank 44 are rotated around a vertical axis.

The case 72 has a space 84 for accommodating the storage tank 44, and has a plurality of holes 86 at its bottom surface for allowing the water flowing out of the storage tank 44 to pass therethrough. The space 84 has a circular bottom slightly larger than the bottom surface of the storage tank 44, in order to facilitate the detachment of the storage tank 44 and the outflow of water from the storage tank 44 during the weft recovery. It is also open upwards.

Water passing through the hole 86 of the case 72 is collected by an upwardly opening element 88 formed in the swivel 68, and is connected to the bottom of the element 88 to communicate with the hole 90. ) Flows through the hole 92 of the support base 66 and the flow path 94 to the reservoir 30.

At the time of weaving, the pressure water is always discharged from the discharge channel 24 to the discharge channel 26 by the pump 32. Thereby, the weft end is conveyed into the pipe 26 and the hose 42 together with the discharged water, and discharged into the receiving tank 44 together with the water from the outlet 96 at the lower end of the hose 42.

During weaving, the motors 60 and 78 rotate continuously or intermittently. As a result, the outlet 96 of the hose 42 is oscillated by the hose moving mechanism 52 so that the position with respect to the receiving tank 44 changes slowly, and the receiving tank 44 is moved by the receiving tank moving mechanism 46. It rotates so that the position with respect to the outlet 96 of the hose 42 changes slowly.

When the reservoir 44 and the outlet 96 move together as described above, since the arrival positions of the water and the weft end into the reservoir 44 vary, the weft end is deposited in the reservoir 44. By varying the position, the weft end is prevented from being concentrated in one place in the receiving tank 44, and the weft end is evenly accommodated in the receiving tank 44. As a result, a large amount of weft end can be accommodated in the storage tank 44 without the need for a human hand, and the number of times of collection work is reduced.

The capacity of the weft end in the receiving tank 44 can be detected by the volume of the weft end, and the height of the weft end in the receiving tank 44 is applied to the weft end sensor 98 such as a photoelectric sensor or an ultrasonic sensor. Can be detected. However, the capacity of the weft end may be detected by detecting the weight of the weft end in the holding tank 44 by a weight sensor such as a strain gauge.

The output signal of the weft-stage sensor 98 is supplied to a weft-stage processing control device (not shown), and a predetermined amount of weft-stage is accommodated in the storage tank 44 and the recovery of the weft-stage in the storage tank 44 is performed. It is used in the upper-stage process control apparatus as a signal notified by an indicator light or the like. Therefore, the worker can receive such a notification by an indicator light or the like, and can recover a sufficient amount of weft ends before overflowing from the receiving tank 44.

In the above embodiment, since the weft end receiving device 10 moves the outlet 96 and the reservoir 44 of the hose 42 together, the position of the water and the weft end into the reservoir 44 is changed. Various changes can be made to accommodate the weft end evenly in the receiving tank 44.

However, only the outlet 96 of the hose 42 may be moved.

Referring to FIG. 3, the weft end receiving device 100 uses the fluid pressure cylinder 104 as a driving source of the hose moving mechanism 102. The hydraulic cylinder 104 is installed to enable the axial movement in the frame 50 by the axial pin 106 extending in the horizontal direction.

The hydraulic cylinder 104 attaches the lower end portion of the hose 42 to the piston rod by the assembling hole 108 so that the upper end of the hydraulic cylinder 104 is discharged from the upper portion together with the water from the upper portion thereof. Thereby, when the piston rod of the fluid pressure cylinder 104 expands and contracts, the discharge port 110 of the lower end of the hose 42 moves in the vertical plane, and the direction of the water flow discharged from the hose 42 is changed.

Therefore, since the position where the weft end is deposited in the receiving tank 44 also changes by the weft end receiving device 100, the weft end is not concentrated in one place in the receiving tank 44, and the storage tank 44 Are evenly accommodated. As a result, a large amount of weft end can be accommodated in the storage tank 44 without requiring a human hand, and the collection | recovery work is reduced.

Referring to Fig. 4, the weft end receiving device 120 is provided with a water flow selection mechanism 122 for changing the water flow discharged toward the receiving tank 44, instead of the hose moving mechanism. In the water flow selection mechanism 122, an aluminum pipe 124 is used in place of the plastic hose, and the pipe 124 is provided on the frame 50 together with the pipe 28 by the assembly holes 126.

The tip of the pipe 124 is connected to a water flow divider 128 that divides the discharged water flow. The water flow divider 128 has a plurality of discharge ports 130 for discharging the weft end together with the water, and the electromagnetic opening / closing valve 132 is disposed at each discharge port 130. The solenoid valve 132 is selectively opened and closed by a control device.

In the upper thread receiving device 120, the solenoid valve 132 that is opened during weaving is selectively changed. As a result, since the actual discharge port is switched and the position where the weft end is deposited in the receiving tank 44 changes, the weft end is evenly accommodated in the receiving tank 44 without being concentrated in one place in the receiving tank 44. . As a result, a large amount of weft end can be accommodated in the storage tank 44 without requiring a human hand, and the collection | recovery work is reduced.

Referring to Fig. 5, the weft end receiving device 140 is provided with a water flow selection mechanism 142 for changing the amount and direction of the water flow discharged toward the storage tank 44, instead of the hose moving mechanism. In the water flow selection mechanism 142, an aluminum pipe 144 is used in place of the plastic hose, and the pipe 144 is installed on the frame 50 together with the pipe 28 by the assembly holes 146.

The tip of the pipe 144 is connected to an electromagnetic flow rate control valve 148 that divides the water flow to be discharged and regulates the flow rate. The electromagnetic flow rate control valve 148 has a plurality of outlets 150 for discharging the weft end together with water.

In the weft end receiving device 140, the opening and closing degree of each outlet 150 is continuously or intermittently changed by the electromagnetic flow rate control valve 148 during weaving. As a result, the flow rate and amount of water discharged from each discharge port 150 are changed, and the flow rate (water strength) is also changed and the direction is also changed. Since the amount and direction of the weft end discharged in accordance with the change of the water flow is also changed, the position where the weft end is deposited in the receiving tank 44 is changed. As a result, since the weft division is accommodated evenly in the accommodation tank 44 without being concentrated in one place in the accommodation tank 44, a large amount of weft division can be accommodated in the accommodation tank 44 without requiring a human hand. And less recovery work.

In the embodiment shown in Figs. 4 and 5, the housing 72 may be moved by rotating the case 72 by an electric motor.

The present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit thereof.
