Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a full and empty tube transfer device in a spinning machine, a twisting machine, a roving frame, etc. (hereinafter referred to as a spinning machine, etc.).

Conventional technology This type of conventional full and empty pipe transfer device has the following features:
As disclosed in Japanese Patent Application Laid-open No. 56-9431,
An endless steel belt is rotatably stretched along the spindle row, pegs for inserting empty tubes are attached to the steel belt at intervals of the spindle pitch or half the spindle pitch, and the steel belt is By pulling and rotating it, the empty tube inserted into the peg is moved.

Conventionally, in order to convey the pirn of a draw-twisting machine, a roller conveyor was disposed in front of the stand of the draw-twisting machine, as disclosed in Japanese Patent Application Laid-Open No. 52-25139, and pegs were placed on the roller conveyor. A pallet with pegs is placed thereon, the pallet with pegs is moved by the rotation of the rollers of a roller conveyor, one end of the roller conveyor is closed, and the pallets with pegs are transferred and stopped in contact with each other. has been proposed.

Problems to be Solved by the Invention In the former type of conventional hollow tube conveyor, the steel belt on which the pegs are attached is very long, so when used for a long period of time, the steel belt stretches and the set interval of the pegs becomes shorter. Even if the reference peg is opposed to the spindle, the further the other pegs are from the reference peg, the more they no longer face the spindle due to the accumulation of peg spacing errors, and automatic tube change is performed in this state. There was a problem in which tube change errors occurred at positions far from the standard peg. In addition, as mentioned above, if there is a large discrepancy in the peg spacing, the mounting position of each peg must be readjusted, but since there are an extremely large number of pegs, it takes an extremely large number of steps to readjust the peg mounting positions. There is a problem in that it requires manpower and time, and there is also a problem in that it requires a lot of manpower and time when replacing the pegs due to damage.

In the case of the latter type of empty tube conveyor, one end of the roller conveyor is closed, and the pallets with pegs are transferred by the rotation of the rollers of the roller conveyor and stopped in contact with each other. Therefore, when the pallet with pegs is stopped, the positional deviation of the pegs due to manufacturing errors of the pallets with pegs is accumulated for all the pallets with pegs on the roller conveyor, and at the other end of the roller conveyor, the peg position is different from the spindle. There is a problem in that the pegs are misaligned to a large extent, resulting in a pipe change error, and in order to reduce the misalignment, it is necessary to increase the machining accuracy of the pallet with pegs, resulting in an increase in cost.
In addition, when fluff gets stuck between the pallet with pegs and the guide rail, the pallet with pegs becomes unable to move, resulting in extremely unstable operation, causing the problem that it cannot be put to practical use in areas with a lot of fluff.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a frame of a spinning machine, etc. with a guide rail that forms a horizontal passage that is open at the top along the spindle row. In the passage of the guide rail, a large number of trays with pegs are formed in the shape of a disk having a diameter equal to or slightly smaller than the spindle pitch or half of the spindle pitch, and the upper surface is fully equipped with pegs for inserting empty tubes. are movably arranged in a line, and the trays with pegs at the rear end of the trays with pegs located in each of the sections where the passage is divided into a plurality of sections are respectively locked to the guide rails to separate the trays with pegs in each section. The present invention is characterized in that a tray moving device is disposed to press and move the trays in groups from one end of the passage toward the other end.

Operation When the tray moving device is activated, the tray moving device locks the trays with pegs at the rear end of the trays with pegs located in each section where the passage of the guide rail is divided into a plurality of sections, and forcefully holds them in a line. The trays with pegs are moved smoothly in one direction, and the trays with pegs are pressed and moved in each group, and then stopped. In its stopped state, the pegs of each pegged tray are arranged at spindle pitches or half spindle pitches depending on the diameter of the pegged tray with reference to the last one of each group, and the pegs of each pegged tray Even if there is a certain manufacturing error in the length dimension, the cumulative error in peg position due to these manufacturing errors is absorbed between each group, and each peg is stopped at a position facing the spindle with high precision. .

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 the spindle rail, 3... is the spindle row 3
a and 3a, which are constructed in a well-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 which is arranged almost horizontally in front of the machine base 1 along the spindle rows 3a, 3a, respectively, and guides a tray with pegs, which will be described later, as shown in Fig. 3. It constitutes a passage H whose upper part is open. 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.
As shown in FIG. 1, this guide rail 5 is made up of a large number of straight rails 5A of appropriate length (for example, a length equivalent to 12 spindle pitches) and four corner rails 5B connected endlessly. It is composed of These straight rails 5A are shown in Figures 6 to 1.
As shown in FIG. The passage H is formed by a 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 passage 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 (same dimension as the spindle pitch P), which will be described later. A large number of trays can be movably arranged in a line within the tray. Further, the corner rail 5B is constructed in substantially the same manner as the linear rail 5A, except that the receiving rail member and the side rail member are bent to draw an arc when viewed from above.
As shown in FIGS. 9 and 10, each of the linear rails 5A is connected to both ends of a connecting plate 11 fixed to a support bracket 6 by fixing bolts 10, and the ends of receiving rail members 5Aa and 5Aa are attached to bolts 12, respectively. , Natsuto 1
3 and are connected to each other. Further, the connection between the straight rail 5A and the corner rail 5B is performed in the same manner as described above. Further, the corner rail 5B is reinforced by a reinforcing piece 14 so as to be able to absorb the large force applied when the tray is moved (see FIGS. 3 and 4). On the upper surface of the receiving rail member 5Aa of the straight rail 5A, the passage H facing the spindle rows 3a, 3a is divided into a plurality of sections (the drawing shows sections divided into 12 spindles). Longitudinal notch holes 15 are provided in the vicinity of positions facing the rearmost (left end in FIGS. 3 and 4) of the trays with pegs. 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 into sections according to the accuracy of the outer diameter of the tray with pegs.

Next, on the endless passage H of the guide rail 5, a tray with a peg (hereinafter referred to as a tray with a peg) is provided with a peg 18 for inserting an empty tube, which protrudes upward from the center of the upper surface of the tray 16. 16) are arranged in a line with their outer diameters touching each other.
The outer diameter of the tray with pegs 16 is the spindle row 3a,
The spindle pitch P of 3a and the outer diameter Q are the same or slightly smaller (within manufacturing tolerances, Q≦
(produced with P). The outer peripheral surface of the tray 16 with pegs constitutes a contact surface 16a that can come into contact with another tray 16 with pegs. Further, a locking recess 17 that is concentric with the outer diameter of the peg tray 16 is formed on the lower surface of the tray 16, and the inner circumferential surface of the locking recess 17 is located at the same height as the contact surface 16a. This constitutes a locking portion 17a. The trays with pegs other than the same number of trays with pegs 16 as the number of spindles corresponding to the spindles may be those without pegs 18 since they are only used for transferring the trays with pegs. Since a large number of these trays 16 with pegs are required, it is preferable to mold them using a synthetic resin material because mass production can be done at low cost.

Next, spindle example 3 of the guide rail 5
Feeding devices 19 for pushing and moving the trays with pegs 16 in groups are provided below the two long straight sections facing a and 3a, respectively, at positions that divide these straight sections into a plurality of sections. These feeding devices 19 constitute a tray moving device. These feeding devices 19 are connected to the notch hole 1.
The pegged trays 16 located in the section where the pegged trays 16 are provided are set as one group, and the locking portions 17a of the rearmost pegged trays 16 are locked with respect to the advancing direction of these groups, and each pegged tray 16 is It is configured so that it can be moved in the advancing direction in groups. Each of the above-mentioned feeding devices 19 has substantially the same configuration except that they share an air cylinder 24 installed at one end of each straight portion of the guide rail 5, and one feeding device 19 will be described below. Note that each feeding device 19 may be provided with one air cylinder. First, a long feed rod 21 extending substantially over the entire length is disposed below the passage H of the 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 of a support bracket 6 for supporting the guide rail 5, and is supported within a receiving rail member 5Aa. 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 21 is moved by the movement of the rod 24a.
is reciprocated by a predetermined amount m.
The piston rod 24a of this air cylinder 24
The stroke amount m is set to be larger than the spindle pitch P and smaller than twice the spindle pitch P. The feed rod 21 is provided with a claw support 26 at a position corresponding to the notch hole 15 of the guide rail 5, as shown in FIGS. It is sandwiched by 27. This claw support 2
6 has a locking portion 17 for the tray 16 with pegs.
The feed pawl 28, which is removable from a, is connected to the tightening bolt 27.
It is pivotably mounted via the. The feed pawl 28 is attached to the mounting bolt 3 on a hanging plate 29 that is slidably hooked onto the lower end of the receiving rail member 5Aa.
When the feed rod 21 is moved backward (leftward in FIG. 6), the front end of the feed claw 28 is moved by the sliding resistance of the weight 31. The locking recess 17 of the tray 16 with pegs is swung downward.
At the same time, the contact piece 28a provided on the feed claw 28 comes into contact with the feed rod 21, and in this state, the feed claw 28 moves below the subsequent tray 16 with pegs. Thereafter, when the feed rod 21 is moved forward, the front end of the feed pawl 28 is swung upward by the sliding resistance of the weight 31 and enters the locking recess 17 of the following tray with pegs 16, and the feed pawl 28 The rear end of the feed claw 28 contacts the feed rod 21, and as the feed rod 21 moves forward, the front end of the feed claw 28 comes into contact with the locking portion 17 of the peg tray 16.
a, push all the trays with pegs in the group by one tray (distance Q) and move to the right, and at the forward end, press peg 1
8 corresponds to the spindle 3.
Therefore, this feed pawl 28 serves both for feeding and positioning the tray 16 with pegs. Furthermore, the above-mentioned feeding device 1
The feeding of the tray 16 with pegs by peg 9 is as follows:
When taking out full tubes from the tray 8 or supplying a plurality of empty tubes at a time, it may be done at a time for a plurality of trays with pegs 16. In addition, the hanging board 29 and the weight 3
1, the feed pawl 28 may be biased counterclockwise in FIG. 6 by a spring. The positional relationship of each of the feed claws 28 with respect to the feed rod 21 is adjusted so that when the feed rod 21 is moved to the forward end, the pegs 18 of the pegged tray 16 exactly oppose the corresponding spindles 3. In FIG. 1, 33 is a full tube discharge device, and 34 is an empty tube supply device.

In the above configuration, when the empty tube inserted into the spindle 3 becomes full, the tube is automatically changed by the tube changing machine running along the machine or by the tube changing device installed on 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 operated automatically or by a manual command to cause the piston rod 24a to move in and out. By the operation of the air cylinder 24, the feed rod 21 is first moved backward by a predetermined amount m from the forward end to the reverse end, and as a result, the front ends of the feed claws 28 of each feed device 19 are attached to the pegs that have been locked until now. It enters the locking recess 17 of the tray 16 with pegs at the rear end of the tray 16 with pegs located in each section that divides the passage H of the guide rail 5 into a plurality of sections, and then moves the feed rod 21 from the reverse end to the forward end. The front end of each feed pawl 28 locks the locking portion 17a of each of the pegged trays 16, and the pegged trays 16 are moved forward by a predetermined distance m, thereby adjusting the length Q, that is, the spindle pitch P. Press and move in groups by approximately equal distances. Therefore, as the air cylinder 24 repeats the movement of the piston rod 24a into and out, each tray with pegs 16 is pegged in groups, with those located in each section of the passage H of the guide rail 5 being divided into a plurality of sections. The full tubes inserted into each peg 18 are intermittently moved by approximately the same size as the diameter dimension Q of the attached tray, and the full tubes inserted in each peg 18 are intermittently moved by approximately the spindle pitch P. In the above case, since the plurality of feed pawls 28 operate simultaneously, all the pegged trays 16 in each group in the passage H move simultaneously while remaining in contact with each other. During the movement, the outer peripheral surface of the tray with pegs 16 touches the side surface of the guide rail (side rail member 5Ab).
(The rotation of the tray with pegs 16 is large when moving around a corner.) Since the contact surfaces that are in contact with each other constantly change, the outer diameter of the tray with pegs may be locally worn. There is no. By repeating the operation of the air cylinder 24, when the trays 16 with pegs that have been sent one after another reach the full tube discharging device 33, the full tubes are removed from the pegs 18 by the device 33, and then the full tubes are removed. An empty tube is inserted into the removed peg 18 by an empty tube supply device 34. When the tray with peg 16 makes one round, the operation of the cylinder 24 is stopped and the feed pawl 28
locks the locking portion 17a of the tray with pegs 16 at the rear end of the group, and the tray with pegs 1 of the group is locked.
6, and the inserted empty tube is placed on the spindle 3.
Opposing the whole weight. At this time, between the tray with pegs 16 where the feed claw 28 is stopped and the tray with pegs 16 that follows, there are A slight gap α (see FIG. 6) corresponding to the cumulative error is generated. Therefore, even if there is a considerable manufacturing error (variation in the manufacturing tolerance range) in the outer diameter Q of each tray with pegs 16 with respect to the spindle pitch P, the cumulative error based on these manufacturing errors can be reduced by the gap α. It is possible to absorb each group, and as a result, each peg 18 and the empty tube inserted therein can be opposed to the corresponding spindle 3 with relatively high precision (within tolerance). This makes it possible to eliminate tube change errors due to misalignment of empty tubes when automatically changing tubes thereafter. The number of groups divided by the feed claw 28 is determined by the manufacturing error of the outer diameter Q of the tray with pegs 16, and the point is that the groups should be divided so as not to cause a tube change error due to the gap α. . Further, as described above, when the feed claw 28 locks the locking portion 17a of the tray with pegs 16 and presses and moves a large number of trays with pegs 16, the locking portion of the tray with pegs 16 hits the tray with pegs 16. Since it is formed at the same height as the contact surface 16a, this tray 1 with pegs is
6 in the direction along the upper surface of the receiving rail member 5Aa to press and move the trays with pegs 16, and to press and move each tray with pegs 16 smoothly in the passage H without causing twisting. Can be done.

Next, FIGS. 11 and 12 show a feeding device 19f which is another embodiment of the feeding device and is capable of continuously feeding the tray 16f with pegs. Reference numeral 39 denotes a drive shaft rotatably disposed in the center of the machine base 1f over substantially the entire length of the machine base 1f, and is adapted to be rotated by a motor (not shown). Reference numerals 40 and 40 designate rotary shafts that are arranged to be rotatable in a direction perpendicular to the drive shaft 39, and a bevel gear 42, which meshes with a bevel gear 41 fixed to the drive shaft 39, is provided at the inner end.
42 are fixed respectively, and a feed wheel 4 is fixed to the outer end of the guide rail 5f directly below the long straight portion of the guide rail 5f.
3 and 43 are respectively attached so that the phase position in the rotational direction can be adjusted. This feed wheel 43 has a plurality of (six in the drawings) feed pawls 43b protruding from the circumferential surface of a disc 43a, and these feed pawls 43b are inserted into the locking recess 17f of the tray with pegs 16f in the passage Hf. It is designed to enter and push the locking portion 17af. The rotating shaft 40 and the feed wheel 43 are respectively installed at positions that divide the long straight section of the passage Hf into a plurality of sections. Therefore, when the drive shaft 39 is rotated, each feed wheel 43 is synchronously rotated in the clockwise direction in FIG. By locking the locking portion 17af of the tray 16f, each tray 16f with pegs can be moved 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 with pegs 16f is transferred by driving the motor as described above, the tray with pegs can be transferred in either the clockwise or counterclockwise direction by rotating the motor in the forward or reverse direction. . When stopping the empty tube at the tube change position that corresponds to all spindle weights, keep the rotation direction of the motor constant (for example, keep the motor always rotating in the forward direction).
The peg-attached tray 16f may be locked and positioned by one predetermined feeding claw 43b of the feeding wheel 43.

In the above embodiment, a locking recess is provided on the lower surface of the tray with pegs, and the tray with pegs is pressed and moved by locking this locking recess, but the present application is not limited to this. Instead, the peg itself or a locking protrusion provided on the lower surface of the tray with the peg may be locked and pressed for movement.

In addition, in the above embodiment, an example was explained in which the guide rails were arranged in an endless manner.
One end of the side guide rail is positioned in an open state on one end side of the machine base (for example, the right side in Fig. 1), and one end of the guide rail is connected to an appropriate transfer means such as a conveyor. The tray with pegs can be taken out from the guide rail and transported to any desired location, and the tray with pegs can also be easily returned to the guide rail. In this way, the full tubes doffed by the spinning machine can be sent to the next process equipment while still being inserted into the pegs, and the empty tubes that have been rewound in the next process equipment can be inserted into the pegs. It can be returned to the spinning machine in its original state. Therefore, it becomes possible to easily automate the transportation of full and empty tubes between a plurality of spinning machines and the next process equipment.

Effects of the Invention As described above, in the present invention, a large number of trays with pegs are arranged in a line in the passage of a guide rail, and the trays with pegs are forcibly locked and moved by a tray moving device. Therefore, by inserting the doffed full tubes into the pegs of the peg-equipped tray, the full tubes can be reliably transported in an established state, and damage to the yarn can be prevented during transportation. In addition, the diameter of each tray with pegs is set to be the same as or slightly smaller than the spindle pitch or half of the spindle pitch, and the trays with pegs located in each section of the guide rail passage divided into multiple sections are treated as one group. Since the trays are pressed and moved in units of groups, even if there is a certain manufacturing error in the diameter dimension of the tray with pegs, the cumulative error in the peg position due to the manufacturing error can be absorbed for each group. The peg can be stopped with high precision at a position facing the spindle, preventing tube change errors. In addition, a large number of trays with pegs arranged in a line in the passage of the guide rail are locked and pressed by a tray moving device, so that each peg can be moved by the tray moving device that moves the trays with pegs. The attached tray can be accurately positioned in the position corresponding to the spindle, the configuration of the tray moving device can be simplified, the cost of the empty tube transfer device can be reduced, and even when used for a long time, deviations in the spacing between each peg can be reduced. This eliminates the need to readjust the peg spacing.
