Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a system for transferring full and empty pipes for automatically changing pipes by a pipe changing machine running along one machine or a pipe changing device installed on the machine. This invention relates to an improvement of a spinning machine equipped with the device.

2. Description of the Related Art Conventional spinning machines have an endless belt (in practice, a steel A belt is used) that is rotatably stretched, and the same number of belts as spindles are attached to this belt at intervals of the spindle pitch.
As disclosed in Japanese Patent Publication No. 43-29205, pegs twice the size of spindles are attached to a belt at intervals of 1/2 spindle pitch, and empty tubes are fully inserted into the pegs for transport.

Problems to be Solved by the Invention A belt with the same number of pegs as the spindle or twice as many as the spindle is very long, so if used for a long period of time, even if a steel belt is used, the belt will stretch and the set pitch of the pegs will go awry. occurs. For this reason, even if the reference peg is placed to face the spindle, a peg that is far from the reference peg will no longer face the spindle due to the accumulation of peg spacing errors, resulting in a pipe change error during automatic pipe change. To prevent this, it may be possible to adjust the mounting position of each peg when the peg spacing becomes inconsistent, but since the pegs are firmly attached to the belt and there are an extremely large number of them, it is difficult to adjust the mounting position of each peg. Adjusting the mounting position requires a lot of manpower and time, which is undesirable.

Also, if one of the many belts breaks, or if a problem such as cracking, cracking, or cutting occurs in one part of the belt, the belt for one car becomes unusable and must be replaced. It won't happen. For this reason, it is necessary to keep a long endless belt with replacement pegs attached at all times, and when replacing it, many pegs must be adjusted so that they accurately face the spindle, which requires a lot of manpower. There were problems such as high maintenance costs, which hindered the operation rate of the spinning machine.

In addition, an automatic empty tube supply device must be installed to supply empty tubes to the pegs on the belt, and in order to transport the replaced full tubes to the winder, the full tubes must be removed from the pegs and placed in a yarn box. Accommodates and workers.

Since the yarn must be transported by conveyor means such as a conveyor truck, it is difficult to automate the process between the spinning machine and the wine gourd, and when a large number of full tubes are stored in a tube box, the yarn layers of the tubes come into contact with each other and become fluffy. This may cause the yarn layer to collapse or be damaged.

Means to solve problems The present invention aims to solve these conventional problems.

Disc-shaped peg trays whose outer diameter Q is the same as the spindle pitch P are arranged in a line inside the guide rail, and the outer diameters of the peg trays are positioned so that they are in contact with each other, so that the spindles and the begs of the peg trays correspond to each other. It is characterized by its composition.

As described above, in the present invention, the spindle and the pegs correspond accurately just by bringing the outer diameter of the disc-shaped peg tray into contact with each other, and the spacing between the pegs does not change even after long-term use. Since the peg trays are each independent, it is possible to send any number of full tubes doffed by the spinning machine to the winder while they are still attached to the pegs, and empty tubes doffed by the spinning machine can be sent to the winder in any number. It is also possible to return the tube to the spinning machine with the tube still attached to the peg.

Embodiments Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, 1 is a frame of a spinning machine, 2.2 is a spindle rail, and 3... is a spindle row 3a.

3a, which are constructed in a known manner. 4 is a full and empty tube transfer device for transferring full and empty tubes in the spinning machine, and is constructed as follows.

First, reference numeral 5 denotes an endless guide rail that is arranged almost horizontally in front of the machine base 1 along the spindle rows 3a, 3a, respectively, and as shown in FIG. It constitutes a transfer path H for guiding the This guide rail 5 is fixedly supported by a support bracket 6 fixed to the machine base 1 and a support stand 7 installed on the floor surface. As shown in FIG. 1, this guide rail 5 has a large number of straight rails 5 of appropriate length (for example, a length corresponding to 12 spindle pitches).
A and four corner rails 5B are connected endlessly. As shown in FIGS. 6 to 10, these straight rails 5A include a receiving rail member 5Aa with a cross-sectional opening shape and a side rail with a rectangular cross-sectional shape attached to the surface side of the receiving rail member 5Aa with screws 8 and nuts 9, respectively. The transfer path H is constituted by a concave groove formed by the upper surface of the receiving rail member 5Aa and the inner surface of the side rail member 5Ab. The width dimension of this transfer path H, that is, the dimension between the opposing inner surfaces of the side rail members 5Ab, 5Ab, is set to a value slightly larger than the outer diameter dimension Q of the tray (the same dimension as the spindle pitch P), which will be described later. A number of trays can be movably arranged in a line in the channel H. Further, the corner rail 5B has substantially the same structure as the straight rail 5A, except that the receiving rail member and the side rail members are bent to form a circular arc when viewed from above.

As shown in FIGS. 9 and 10, each of the linear rails 5A is provided with receiving rail members 5Aa and 5Aa, respectively, at both ends of a connecting plate 11 fixed to the support bracket 6 with fixing bolts 10.
The ends of the two are attached and connected to each other by bolts 12 and nuts 13.

Further, the connection between the straight rail 5A and the corner rail 5B is performed in the same manner as described above. Also corner rail 5B
The receiving rail member 5A of the straight rail 5A is reinforced by a reinforcing piece 14 (see FIGS. 3 and 4) so that it can stop the large force received when the tray moves.
On the upper surface, there is a rearmost tray (the third A notch hole 15 long in the longitudinal direction is provided in the vicinity of a position opposite to the one located at the left end (in FIG. 4). Although it is preferable that the number of weights in each section is approximately the same, it is not necessary that they all be approximately the same, and the number of weights may be divided as appropriate depending on the accuracy of the outer diameter of the tray.

Next, on the endless transfer path H of the guide rail 5, the spindle pitch P and outer diameter Q of the spindle rows 3a, 3a are the same over the entire length (in practice, Q≦ within the manufacturing tolerance).
Disc-shaped trays 16 (manufactured by P) are arranged in a line with their outer diameters touching each other. It is preferable that the tray 16 is hollow as shown in the figure in order to reduce the weight and stabilize it when placed. In this embodiment, the inner circumferential surface 17 of the hollow recess 17
A is used as a locking part for feeding the tray 16.

A peg 18 for inserting a droplet or an empty tube is protruded from the center of the upper surface of the tray 16, and the peg 18 corresponds to the spindle 3. The trays other than the trays 16 of the same number as the spindles corresponding to the spindles may be those without pegs 18 because they are only used for transferring trays. Since a large number of these trays 16 are required, it is preferable to mold them using a synthetic resin material because mass production is possible at low cost.

Next, the spindle rows 3a, 3a of the guide rail 5 are
A feeding device 19 is disposed below the two long straight sections facing each other to push and move the trays 16 in groups to positions that divide these straight sections into a plurality of sections. These feeding devices 19 are configured so that the trays 16 located in the section where the notch holes 15 are provided are considered as one group, and each tray 16 can be moved in the traveling direction in units of groups with respect to the traveling direction of these groups. has been done. That is, a single long feed rod 21 extending substantially over the entire length is disposed below the transfer path H, which is a long straight portion of the guide rail 5, so as to be movable in the longitudinal direction along the guide rail 5.

As shown in FIG. 9, this feed rod 21 is slidably inserted into a support hole 22 formed in a support bracket 6 for supporting the above-mentioned guide rail 5, and is inserted into the receiving rail member SA.
It is supported within a. The end of the feed rod 21 in the advancing direction is connected via a connector 25 to a piston rod 24a of an air cylinder 24 which is pin-connected to a pivot 23 fixed to the machine base 1. The feed rod 2 is moved by the movement of the piston rod 24a.
1 is reciprocated by a predetermined amount m. The stroke amount m of the piston rod 24a of the air cylinder 24 is set to be larger than the spindle pitch P and smaller than twice the spindle pitch P. The feed rod 21 has a claw support 26 at a position corresponding to the notch hole 15 of the guide rail 5, as shown in FIG. 6 and FIG. 27. This claw support 26
A feed pawl 28, which is removable from the inner circumferential surface 17a of the tray 16, is pivotably attached to the upper end via the tightening bolt 27. This feed claw 28 is connected to the receiving rail member 5Aa.
The feed rod 21 is connected via a rod 32 to a weight 31 attached by a mounting bolt 30 to a hanging plate 29 slidably hooked onto the lower end of the feed rod 21 (leftward movement in FIG. 6). ), the front end of the feed pawl 28 is swung downward by the sliding resistance of the weight 31 and detached from the recess 17 of the tray 16, and the contact piece 28a provided on the feed pawl 28 comes into contact with the feed rod 21. contact.

In this state, the feed claw 28 moves below the succeeding tray 16. Thereafter, when the feed rod 21 is moved forward, the front end of the feed claw 28 is swung upward by the sliding resistance of the weight 31 and enters the recess 17 of the succeeding tray 16, and the rear end of the feed claw 28 is moved upwardly by the sliding resistance of the weight 31. 21, and by the subsequent forward movement of the feed rod 21, this feed claw 2
The front end of 8 engages with the inner circumferential surface 17a of the tray 16, pushes all the trays of the group by one tray 16 (distance Q), moves to the right, and holds the forward end ↓ of the tray 16 and moves it to the right.
corresponds to spindle 3. Therefore, this feeding claw 28 serves both for feeding and positioning the tray 16. In the first @, 33 is a full tube discharge device, and 34 is an empty tube supply device.

In the above configuration, when the empty pipe inserted into the spindle 3 becomes full, the pipe is automatically replaced by a pipe changing machine running along one machine or a pipe changing device installed in the machine. , an empty tube is inserted into the spindle 3, and a full tube is inserted into the peg 18. After the pipe change is completed, the air cylinder 24 of the feeding device 19 is actuated automatically or by a manual command to cause the piston rod 24a to move in and out. As a result of the operation of the air cylinder 24, the feed rod 21 moves back by a predetermined amount m and then returns to the forward end, as described above, the feed claw 28 pushes the group of trays 16 and moves them by one tray, that is, the distance of the spindle pitch P. Since the plurality of feed claws 28 operate simultaneously, all the trays 16 in the transfer path H move simultaneously while remaining in contact with each other. During the movement, the tray 16 comes into contact with the side surface of the guide rail (side rail member 5Ab) and is rotated little by little (when moving around a corner, the tray 16
(large rotation) The contact surfaces that are in contact with each other constantly change, so the outside diameter of the tray does not wear out in extreme parts.
By repeating the operation of the air cylinder 24, when the trays 16 sent one after another arrive at the full tube discharge device 33, the full tubes are removed from the pegs 18 by the interlayer [33, and then the full tubes are removed. Empty tube supply device 34 to bed 18
The empty tube is inserted. When the tray 16 makes one round, the operation of the cylinder 24 is stopped, and the feeding claw 28 locks the inner circumferential surface 17a of the rearmost tray 16 of the group to position the tray 16 of the group and remove the inserted empty tube. faces all spindle 3 spindles. At this time, there is a tray 16 between the tray 16 where the feeding claw 28 is stopped and the following tray 16.
A small gap α(
(see FIG. 6), but since the gap is absorbed for each group, the empty tube and spindle can be opposed with high precision. Therefore, when performing an automatic pipe change afterwards,
It is also possible to eliminate pipe replacement errors due to misalignment of empty pipes.

The division into groups by the feed pawl 28 is determined by the manufacturing error of the outer diameter Q of the tray 16, and when the outer diameter Q is manufactured with high precision (Q=P), the R side and L side of the spinning machine are made into one group respectively. be able to. The point is that the groups should be divided using the gap α to avoid tube change errors.

Next, FIGS. 11 and 12 show another embodiment of the feeding device 19f that can continuously feed the tray 16f.
It shows. Reference numeral 39 denotes a drive shaft rotatably disposed in the center of the machine 1f over almost the entire length of the machine 1f, and is rotated by a motor (not shown). 40.
Reference numeral 40 denotes a rotating shaft rotatably disposed in a direction perpendicular to the drive shaft 39, and bevel gears 42 and 42 that mesh with a bevel gear 41 fixed to the drive shaft 39 are respectively fixed to the inner end, and the outer end Feed wheels 43 and 43 are respectively mounted directly below the long straight portions of the guide rails 5f so that their phase positions in the rotational direction can be adjusted. This feed wheel 43 has a plurality of (six in the drawings) feed pawls 4 on the circumferential surface of a disc 43a.
3b is provided protrudingly.

These feed claws 43b enter into the recess 17f of the tray 16f in the transfer path Hf and push the inner circumferential surface 17af. The rotating shaft 40 and the feed wheel 43 are the transfer path Hf.
Each is installed at a position that divides a long straight section into multiple sections. Therefore, when the drive shaft 39 is rotated, each feed wheel 43
are synchronously rotated in the clockwise direction in FIG. 12, and the trays 16f located in each section are treated as one group, and the inner circumferential surface 17af of the rearmost tray 16f of these grules is
It is possible to lock each tray 16f and move each tray 16f continuously in groups. It should be noted that parts that are considered to have the same or equivalent configuration as those of the above-mentioned embodiments are given the same reference numerals as the corresponding parts with the letter f, and redundant explanations are omitted.

When the tray 16f is transferred by driving the motor in this way, the tray can be transferred in either of the clockwise and counterclockwise directions by rotating the motor forward or backward. When the empty tube is stopped at the tube changing position corresponding to all spindle weights, the rotation direction of the motor is kept constant (for example, the motor is always rotated in the forward direction) feed wheel 43
It is sufficient to lock the tray 16f with one predetermined feeding claw 43b and place it in the position chamber.

In this way, the feeding device of the present invention transports the tray so that when the tray is stopped at the tube change position, the outer diameters of the trays abut each other and are placed in the position chamber, and the spindle and empty tube correspond. It is fine as long as it is suitable for the location. For example, Tokuko Sho 5
It goes without saying that the tray placed on a conveyor and transferred may be brought into contact with a stopper and correspond to a spindle as in the publication of 6-41525. In any case, the present invention When the outer diameters of the trays placed in the guide rail come into contact with each other, the guide rail restricts the lateral movement of the trays that try to escape in the width direction of the guide rail, so the same number of trays as the spindles are kept in a row. The spindle and tray pegs correspond. In the above embodiment, the lateral movement of the tray is controlled by the outer diameter of the tray, but a guide cylindrical base is provided on the outer diameter of the peg or at the base of the peg, and the lateral movement of the tray is controlled by the peg or the cylindrical base. Needless to say, it is also good to have the guide rails arranged in an endless manner in the above embodiment. (for example, on the right side in Figure 1), and by connecting one end of the guide rail to an appropriate transport means such as a conveyor, the tray can be taken out from the guide rail and transported to an arbitrary location. Moreover, it is also possible to easily return the tray that has been taken out to the guide rail. In this way, the full tube doffed by the spinning machine can be sent to the winder while still attached to the peg, and the empty tube that has been rewound in the winder can be sent to the winder while still being inserted into the peg. It can be returned to the spinning machine. Therefore, it is possible to easily automate the conveyance of full tubes and empty tubes between a plurality of spinning machines and wine goos.

Effects of the Invention As described above, according to the present invention, the outer diameter of the tray is made the same size as the spindle pitch, so the peg of the tray can be accurately aligned with the spindle simply by abutting the outer diameter of the tray placed inside the guide rail. It can be made to correspond. The tray placed inside the guide rail comes in contact with the guide rail during movement and is rotated little by little, so that the contact surface constantly changes, so the contact surface does not wear out locally, so it can last for a long time. Even when used, there is no deviation in peg spacing, no tube change errors occur during automatic tube change, and the guide rail transfer path is divided into appropriate groups according to the outside diameter accuracy of the tray, which reduces the accumulation It is suitable for long spinning machines with a large number of spindles because it can absorb errors and match with the spindle, and the trays are individually arranged within the guide rail, making it easy to insert empty tubes into the pegs. It is possible to easily send any number of yarns to the next process or return them to the guide rail while still attached, and the yarn layer does not collapse or be damaged when a full tube is transferred.

Furthermore, even if one tray breaks, it is only necessary to replace that one tray, so there is almost no maintenance cost.
