JPH07844B2 - Bobbin transfer device for spinning machine - Google Patents

Description

The present invention relates to a bobbin transfer device in a spinning machine, and more particularly, to a front face of a spinning machine such as a ring spinning machine and a ring twisting machine connected to a winder process. The present invention relates to a bobbin transfer device that supplies empty bobbins according to a spindle pitch prior to a doffing operation by an automatic doffing device.

(Prior Art) Conventionally, a fully spun full bobbin is once housed in a magazine box, and then, the required number of bobbins are taken out from the magazine box and transported to a winder. Therefore, a magazine box for collecting and storing full bobbins is required,
The bobbin surface becomes fluffy during storage and transfer,
There was a defect that the yarn layer collapsed or the yarn ends were entangled, making it difficult to find the yarn. In order to solve such a problem, a spinning-winder of a type in which a winder of a spinning machine is connected and a doffed full bobbin is directly sent to the winder for rewinding has been proposed and implemented.

Japanese Patent Application No. 50-136440, published October 29, 1975, discloses a bobbin of this type as a spinning winder, in which a large number of pegs corresponding to the spindle are planted on the spinning machine side to convey a full bobbin. Provided with a conveyer conveyor, the winder side is provided with a conveyer for conveying a full bobbin supplied from the spinning process and an empty bobbin after winding, and a full bobbin fried by a spinning machine is used as a peg of the bobbin conveyer. The bobbin carrying yarn is arranged between the bobbin carrying conveyor and the carrying means while holding and moving the bobbin carrying conveyor one pitch at a time in response to the pipe system replenishment signal in the winder process and sequentially removing the full bobbins on the carrying conveyor. A device for supplying to the winder via a replenishing device is disclosed. However, in this spinning winder, when the full bobbin is transported from the spinning process to the winder process, the full bobbin that is fried on the peg of the bobbin transport conveyor is removed and passed to the transport means in the winder process, which complicates the device. There is a problem of becoming.

In order to solve this problem, for example, Japanese Utility Model Laid-Open No. 60-50665, published on April 9, 1985, conveys a full bobbin and an empty bobbin in a spinning process and a winder process, and a peg is projected on the upper surface. There is also proposed a device which is slidably supported by a guide rail and which is carried by a belt conveyor or a sliding body which is carried by a cylinder or the like. In this device, the full bobbin fried by the spinning machine is transferred to the winder process while being inserted into the peg of the sliding body, and the empty bobbin after the yarn is wound by the winding unit is placed on the peg of the sliding body. It is inserted and returned to the spinning process.

(Problems to be Solved by the Invention) In the device for transporting the bobbin using the sliding body, the sliding body in which the empty bobbin returned from the winder process to the spinning process is inserted is randomly arranged on the belt conveyor. Therefore, it is necessary to convey the sliding body returned from the winder process to the front surface of the spinning machine with the peg interval corresponding to the spindle pitch of the spinning machine. As a method of arranging the peg spacing of the sliding body in a state corresponding to the spindle pitch of the spinning machine, conventionally, the diameter of the sliding body was formed to be the same as the spindle pitch, and each sliding body was abutted against each other in the spindle row. It was designed to be conveyed along a predetermined position. However, the spindle pitch is not constant in all spinning machines, and currently, different gauge widths in the range of 63 to 80 mm are generally used. In many cases, a plurality of machine bases having different spindle pitches are provided in the same factory. In that case, it is necessary to prepare a large number of sliding bodies having different diameters, which raises a problem of high manufacturing cost. At present, the number of spindles for spinning machines is generally about 200 on each side, but it is also aimed at making multiple spindles. Even if there are 200 spindles on one side, if the manufacturing error of the sliding body is 0.1 mm, the accumulated position will cause an error of 20 mm in the arrangement position of the peg and the spindle on the sliding body, which will hinder the doffing work by the doffing machine. .

As a means for eliminating the inconvenience caused by the accumulation of manufacturing errors, Japanese Patent Laid-Open No. 57-161133 published on October 4, 1982 discloses a guide rail 32 for supporting and guiding a sliding body 31 as shown in FIG. An air cylinder 35 reciprocally operates a rod 34 provided below with a plurality of engaging members 33 engageable with a locking recess 31a formed on the lower surface of the slide body 31 on the guide rail 32 at predetermined intervals. A feeding device has been proposed which presses and moves a plurality of sliding bodies placed on the 32 in a state of abutting each other. When this device is used, even if there is a manufacturing error in the diameter of the sliding body 31, the sliding body 31 is pressed and moved by a plurality of groups by each engaging member 33. By staying within the corresponding accumulated error and adjusting the number of the sliding bodies 31 of each group, that is, the number of the engaging members 33, the doffing can be arranged without any trouble. However, this device has a problem that the structure is complicated and the cost is high. Further, since the sliding body 31 is intermittently transferred by this device, there is a problem that it takes a long time to complete the supply of the empty bobbin to the front surface of the spinning machine base.

(Means for Solving the Problems) In order to solve the above problems, in the present invention, a guide rail for guiding a sliding body having a length shorter than a spindle pitch having a peg projectingly provided on an upper surface thereof, and the sliding body A conveyor device composed of an endless belt conveyor for transporting the sheet was extended along the spindle row of the spinning machine stand. A regulating member driven in synchronization with the belt conveyor so as to engage with the sliding body continuously supplied on the continuously driven belt conveyor for a predetermined time. It was arranged at the end.

(Operation) In the present invention, the sliding body having a length shorter than the spindle pitch is continuously supplied onto the endless belt conveyor in a state of being supported by the guide rail, and the spinning machine is placed on the belt conveyor. It is transported to the front of the table. And
While being placed on the belt conveyor, it engages with a regulating member arranged at the sliding body entry side end of the conveyor device for a predetermined time, and its movement is regulated so that the interval between the pegs of each sliding body is predetermined. The sheets are sequentially transported in a state of being regulated to the value of.
By adjusting the engagement time between the regulation member and the sliding body, the distance between the sliding bodies placed on the belt conveyor is regulated to a predetermined value corresponding to the spindle pitch.

(Embodiment 1) One embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 2, a plurality of spinning machines 1 and winders 2 arranged in parallel are connected by a conveying path 3, and a full bobbin fried in the spinning machine 1 is conveyed to the winder 2 through the conveying path 3. In addition, the empty bobbin after the yarn is wound by the winder 2 is returned to the spinning machine 1 via the transport path 3.

On both left and right sides of the machine frame of the spinning machine 1, conveyor devices 5 are extended along the four rows of spindles. The conveyor device 5 is composed of a guide rail 7 having a cross-section, which guides a sliding body 6 having a peg 6a protruding from the upper surface thereof, and an endless belt conveyor 8 which conveys the sliding body 6. As shown in FIG. 1, the belt 9 of the belt conveyor 8 is arranged so as to slide on the guide rail 7 in order to prevent bending when a large number of sliding bodies 6 are placed on the upper surface thereof. .

A rotary shaft 10 is vertically supported in the vicinity of an end of the conveyor device 5 on the sliding body 6 entry side. The upper end of the rotary shaft 10 is engaged with the slide body 6 placed on the belt conveyor 8 and transported along the guide rail 7, and the pitch between the pegs on each slide body is regulated to a value equal to the spindle pitch. A restricting member 11 for doing so is integrally rotatably fitted. The regulation member 11 is formed in a disc shape, and a plurality of (four in this embodiment) engageable with the pedestal portion 6b which supports the lower end of the bobbin 12 fitted into the peg 6a on the outer peripheral portion thereof. Grooves 13 are formed at the same pitch as the spindle pitch and at equal intervals at positions where two sliding bodies can be simultaneously engaged. The rotating shaft 10
A driven gear that meshes with a drive gear 17 fitted and fixed to a drive shaft 16 of a drive pulley 15 that is rotated by a motor 14 in order to drive the regulating member 11 in synchronization with the belt conveyor 8 at the lower end of the 18 is fitted and fixed. Drive gear 17
The gear ratio between the driven gear 18 and the driven gear 18 is set to a value at which the moving speed of the belt 9 and the peripheral speed of the engaging groove 13 of the regulating member 11 are the same. Further, detection switches PH1R and PH1L for detecting the presence or absence of the sliding body 6 to be engaged with the regulating member 11 are provided at the sliding body entrance end of the conveyor device 5, and the motor 14 is driven when the PH1R and PH1L are OFF. Is performed only when a signal for reverse rotation (to carry out the yarn from the spinning frame) is input, and when PH1R and PH1L are in the ON state, when the signal for normal rotation (supplying an empty bobbin to the spinning frame) is input, the motor 14 turns on. When the sliding member 6 is rotated in the forward direction and the leading slide body 6 is detected by the detection switches PH2R and PH2L arranged at the end of the conveyor device 5, the motor 14 is stopped. As shown in FIG. 5, the transport path 3 has a slanted connecting portion with the guide rail 7,
The sliding body 6 slides down onto the belt 9 by its own weight. Further, when the transport path 3 is horizontal, it is possible to drive the conveyor belt and move the sliding body 6 to the conveyor device 5.

Next, the operation of the device configured as described above will be described. Empty bobbin 12 after the thread is wound by winder 2 is a peg
When the motor 14 is driven in a state where the slide body 6 fitted in the 6a is sequentially supplied to the inlet side end of the conveyor device 5 of the spinning frame 1 via the transport path 3, the drive pulley 15 is driven. At the same time, through the driving gear 17 and the driven gear 18, the regulating member
11 is rotated clockwise with the rotating shaft 10 in FIG.
The movement of the sliding member 6 placed on the belt 9 is restricted at the position shown by the chain line in FIG. After the pedestal portion 6b engages with the engaging groove 13 as shown by the solid line in FIG. 6 (a) along with the movement, the guide rail 7 is moved while moving inside the engaging groove 13 toward the center of the regulating member 11. Move along arrow A. From the time when the straight line connecting the engaging groove 13 engaged with the pedestal portion 6b and the rotation center of the regulating member 11 has passed the position orthogonal to the guide rail 7, the pedestal portion 6b moves outward from the engaging groove 13. The guide rail 7 moves along the guide rail 7 in the direction of the arrow A while moving toward the guide rail 7.
After moving to a position forming an angle of 45 ° with, the engagement with the engaging groove 13 is released, and it moves in the direction of arrow A. In this state, the pedestal portion 6b of the next slide body 6 is engaged with the next engagement groove 13. Since the peripheral speed of the outer peripheral portion of the regulating member 11 is rotationally driven at the same speed as the belt moving speed of the belt conveyor 8, the sliding body 6 receives a pressing force when the engagement with the engaging groove 13 is released. Instead, it moves at the same speed as the moving speed of the belt 9.

Similarly, the pedestal portion 6b of the sliding body 6 is sequentially engaged with the engaging groove 13 of the regulating member 11 and fed one by one. In the case of this device, the spacing between the pegs 6a of each sliding body 6 sent out through the regulating member 11 becomes the same state again by rotating the regulating member 11 by 90 ° from the state shown in FIG. 6 (b). It is the distance that the belt 9 of the belt conveyor 8 moves in the meantime. In this embodiment, since the moving speed of the belt 9 and the peripheral speed of the outer circumference of the regulating member 11 are set to be the same, the distance is 1/4 of the outer circumference of the regulating member 11. Therefore, by making the 1/4 length of the outer periphery of the regulating member 11 the same as the spindle pitch, the sliding body 6 is placed on the belt 9 in a state where the distance between the pegs 6a corresponds to the spindle pitch. It is supplied in front of the spinning machine 1.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. In the above embodiment, a plurality of engaging grooves are used as the regulating member for regulating the movement of the sliding body by engaging the sliding body for a predetermined time.
Although the regulating member 11 having 13 and continuously rotating in synchronism with the belt conveyor 8 is used, in this embodiment, the operation position for preventing the movement of the sliding body 6 on the belt conveyor 8 and the movement of the sliding body 6 are used. The present embodiment is significantly different from the above-described embodiment in that a turning lever 19 that is intermittently moved and arranged at a retracted position that allows the above is provided as a regulating member. The turning lever 19 is rotatably supported on the support shaft 20, and has a cam follower at its base end.
Equipped with 21. The cam follower 21 is fitted on the upper end of the rotary shaft 22 rotated via a driven gear (not shown) that meshes with a drive gear (not shown) fitted to the drive shaft 16 of the drive pulley 15 as in the above embodiment. An action orthogonal to the guide rail 7 in a state of being urged by a spring 24 in a direction in which it abuts against the fixed cam 23 (counterclockwise direction in FIG. 7) and abuts on a small diameter portion of the cam 23. It is arranged at a position, and when it comes into contact with the large-diameter portion, it is rotated clockwise from that state and is arranged at a retracted position that allows movement of the sliding body 6. Therefore, in this device as well, after the engagement between the rotary lever 19 and the sliding body 6 is released, the belt conveyor 8 is released before the next engagement between the sliding body 6 and the rotary lever 19 is released. By setting the moving distance of the belt 9 to be the same as the spindle pitch, the sliding body 6 can be sequentially fed onto the belt 9 of the belt conveyor 8 in a state corresponding to the spindle pitch.

The present invention is not limited to the above-described embodiments, and for example, the belt conveyor 8 and the regulating member 11 arranged on both left and right sides of the spinning machine 1 may be configured to be driven by one motor. A range in which the size of the regulating member 11 and the number of the engaging grooves 13 are changed, a regulating member driven by a solenoid is provided in place of the rotating lever 19 in the second embodiment, and the like does not depart from the gist of the present invention. In, it is also possible to arbitrarily change the shape, configuration, etc. of each part.

EFFECTS OF THE INVENTION As described in detail above, according to the present invention, it is not necessary to prepare many kinds of sliding bodies having pegs into which bobbins are fitted and inserted according to the spindle pitch, and sliding bodies of the same size are used. Even though the sliding body corresponding to the spindle pitch can be transported to the front of the spinning machine stand, the structure of the device is simple and the cost can be reduced, and the pegs can be transferred continuously instead of intermittently. Therefore, there is an excellent effect that the supply time to the front surface of the spinning machine stand can be shortened.
