Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device for conveying full and empty tubes of spinning machines, twisting machines, roving frames, etc. (hereinafter referred to as spinning machines, etc.). This relates to a tray with pegs.

BACKGROUND TECHNOLOGY In the conventional conveying device for full and empty tubes of this type, an endless steel belt can be rotated along a spindle row, as disclosed in Japanese Patent Application Laid-Open No. 56-9431. The pegs for inserting the empty tube are attached to this steel belt keeping the spacing of the spindle pitch, and the steel belt is pulled and rotated to insert the peg into the peg.
It is designed to move empty tubes.

Conventionally, in order to convey the pirns of a draw-twisting machine, a pallet with pegs is placed on a roller conveyor as disclosed in Japanese Patent Application Laid-open No. 52-25139, and the pegs of the pallet with pegs are filled with the pegs. It has been proposed to insert and move an empty tube.

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. Furthermore, if the spacing between the pegs becomes incorrect, the mounting position of each peg must be readjusted, but since there are so many pegs, it takes an extremely large amount of manpower and time to readjust the peg mounting positions. There were also problems in that it required a lot of manpower and time to replace the pegs due to breakage, etc.

In addition, in the latter case, the pallet with pegs is placed on a roller conveyor, and the pallet with pegs is transferred by the rotation of the rollers of the roller conveyor. There was a problem in that the pallet with pegs would not move when the fluff got stuck between it and the rail, making it impractical in areas where there was a lot of fluff, such as around cotton spinning machines. Moreover, the spindle pitch of the spinning machine is
Since it is small (90 mm or less), the diameter of the pallet with pegs becomes small, and the roller spacing of the roller conveyor must be made small.The cost of the roller conveyor becomes extremely high, making it difficult to put it into practical use. The reality is that the former type of device is still being used as the empty tube transfer device.

Means for Solving the Problems The present invention aims to solve the above problems by providing a tray with pegs for transporting empty tubes, which has an outer diameter that is similar to the spindle pitch or spindle pitch of a spinning machine. Forming a locking recess concentric with the outer diameter of the disk-shaped tray on the bottom surface of the disk-shaped tray having the same dimensions as the half, and using the inner surface of the locking recess as a locking portion for transferring and positioning the tray itself; It is characterized in that the outer circumferential surface of the tray is formed into an abutting surface for abutting against another tray with pegs, and the tray and the pegs are integrally molded from a synthetic resin material.

Function When a large number of trays with pegs for transporting full or empty tubes are movably arranged in a row in the passage of a guide rail arranged along the spindle rows of a spinning machine, etc., full or empty tubes can be transferred to the pegs of each tray with pegs. Empty tubes can be inserted in the erected state, and by moving the tray with pegs in this state, the full or empty tubes can be transferred to any desired position in the erected state. The locking part on the inner surface of the locking recess of the tray with pegs placed in the passage of the guide rail is locked and forcibly moved, so that the contact surfaces of the trays with pegs are in contact with each other. By stopping at , each peg and pitch can be made identical to the spindle pitch or half of the spindle pitch,
Furthermore, each peg can be positioned with reference to the pegs of the locked tray with pegs, and the pegs can be made to correspond accurately to the spindle. Further, the tray with pegs can be locked at a position approximately at the same height as the contact surface of the tray, and can be transported in a stable state.

Embodiment Next, an embodiment in which the tray with pegs for conveying full and empty tubes of the present invention is used in a device for transferring full and empty tubes in a spinning machine or the like will be described in detail with reference to the drawings. 1st
In the figure, 1 is a frame of a spinning machine, 2, 2 are spindle rails, and 3... are spindle rows 3a, 3a.
These spindles 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 that is arranged approximately 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. 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. This guide rail 5 has an appropriate length (for example, 12 mm) as shown in Figure 1.
A large number of straight rails 5A (length equivalent to the spindle pitch) and four corner rails 5B.
are connected in an endless manner. As shown in FIGS. 6 to 10, these straight rails 5A include a cross-sectional receiving rail member 5Aa and an L-shaped cross-sectional side attached to both sides of the receiving rail member 5Aa with screws 8 and nuts 9, respectively. Rail member 5Ab, 5
The passage 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 passage H, that is, the side rail members 5Ab, 5
The dimension between the opposing inner surfaces of Ab is set to a value slightly larger than the outer diameter dimension Q (same dimension as spindle pitch P) of the tray with pegs, which will be described later, and a large number of trays with pegs are arranged in a line in this passage H. It is designed so that it can be moved and placed. 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. Each of the above straight rails 5A is shown in Figures 9 and 10.
Attach the fixing bolt 1 to the support bracket 6 as shown in the figure.
The ends of the receiving rail members 5Aa and 5Aa are attached to both ends of the connecting plate 11 fixed by bolts 12 and 0, respectively.
They are attached and connected to each other by nuts 13. Also, straight rail 5A and corner rail 5B
Connection with is also performed in the same manner as above. In addition, the corner rail 5B has reinforcing pieces 14 so that it can absorb the large force received when the tray with pegs is moved.
(See Figures 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 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, which has a peg 18 for inserting an empty tube, which protrudes upward from the center of the upper surface of the tray 16. The trays (referred to as trays 16) are arranged in a line over the entire length with their outer diameters touching each other. The outer diameter Q of the tray 16 with pegs is set to be the same size as the spindle pitch P of the spindle rows 3a, 3a (in practice, it is manufactured within the range of manufacturing tolerances so that Q≦P). The outer peripheral surface of the tray 16 with pegs is similar to that of the tray 16 with pegs.
It constitutes a contact surface 16a that can be brought into contact with. Further, a locking recess 17 is formed on the lower surface of the tray with pegs 16 and is concentric with the outer diameter of the tray. 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. These trays 16 with pegs are integrally molded from a synthetic resin material so that a large number of them can be mass-produced at low cost.

Next, the spindle row 3 of the guide rail 5
Feeding devices 19 for moving the trays with pegs 16 in groups are disposed 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 a tray 16 with pegs located in the section where the notch hole 15 is provided.
are regarded as one group, and the locking portion 1 of the tray with pegs 16 at the rear end with respect to the direction of movement of these groups is
7a is locked so that each tray with pegs 16 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. An air cylinder 2 is connected with a pin to a pivot 23 fixed to the machine base 1 at the end of the feed rod 21 in the direction of movement.
The feed rod 21 is connected to the piston rod 24a of the air cylinder 24 via a coupling member 25, and as the piston rod 24a of the air cylinder 24 moves in and out, the feed rod 21 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, which is tightened so that the longitudinal position of the feed rod 21 can be adjusted as shown in FIGS. 6 and 7. It is clamped by bolts 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 and moves all the trays with pegs in the group by one tray (distance Q) to the right, so that the pegs 18 correspond to the spindle 3 at the forward end. . Therefore, this feed pawl 28 serves both for feeding and positioning the tray 16 with pegs. Note that the feeding of the trays 16 with pegs by the feeding device 19 may be carried out by a plurality of trays with pegs 16 when taking out full tubes from the pegs 18 or supplying a plurality of empty tubes one by one. Further, instead of using the hanging plate 29 or the weight 31, 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 the pegs 18 on the peg tray 16 exactly oppose the corresponding spindles 3 when the feed rod 21 is moved to the forward end. 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 actuated 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. Move 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 attached tray is intermittently moved by approximately the same dimension as the length dimension Q, 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 claws 28 operate simultaneously, all the contact portions 16a of the pegged trays 16 in each group in the passage H move simultaneously while remaining in contact with each other. During the movement, the tray with pegs 16
The outer peripheral surface of the side rail member 5 is the side surface of the guide rail (side rail member 5
Ab) and rotated little by little (the rotation of the tray with pegs 16 is large when moving around a corner), and the contact surfaces that are in contact with each other constantly change, causing local wear on the outer peripheral surface of the tray with pegs. There's nothing to do. 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. Empty tube supply device 34 to the taken peg 18
An empty tube is inserted by. Tray with peg 16
After one cycle, the cylinder 24 stops operating, and the feed claw 28 moves the tray 1 with pegs at the rear end of the group.
The pegged tray 16 of the group is positioned by locking the locking portion 17a of 6, and the inserted empty tube faces all the spindles 3. At this time, between the tray with pegs 16 where the feeding claw 28 is locked and the subsequent tray with pegs 16, the tray with pegs 16
A small gap α (see FIG. 6) is created, which corresponds to the cumulative error of each group based on the manufacturing error (variation within the manufacturing tolerance range) of the outer diameter Q of . Therefore, even if there is a considerable manufacturing error (variation in the manufacturing tolerance range) in the outer diameter Q of each pegged tray 16 with respect to the spindle pitch P, the cumulative error based on these manufacturing tolerances can be calculated by the gap α. 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 also makes it possible to eliminate tube change mistakes due to misalignment of empty tubes when automatically changing tubes afterwards. 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 feeding claw 28 locks the locking portion 17a of the tray with pegs 16 to move a large number of trays with pegs 16, the locking portion of the tray with pegs 16 comes into contact with the tray with pegs 16. Since it is formed at the same height as the surface 16a, the tray with pegs 16 can be moved by applying a large force to the tray with pegs 16 in the direction along the upper surface of the receiving rail member 5Aa. is completed, and each tray 16 with pegs is connected to the passage H.
It can be moved smoothly inside without any twisting.

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 almost the entire length of the machine base 1f, and is adapted to be rotated by a motor (not shown). 40,40
is a rotary shaft arranged to be rotatable in a direction perpendicular to the drive shaft 39, and a bevel gear 4 that meshes with a bevel gear 41 fixed to the drive shaft 39 is provided at the inner end.
2 and 42 are fixed to each other, and feed wheels 43 and 43 are respectively attached to the outer ends of the guide rails 43 and 43 directly below the long straight portion of the guide rail 5f so that their phase positions in the rotational direction can be adjusted. This feed wheel 43 is a disc 4
There are multiple (six in the drawing) feed claws 4 on the circumference of 3a.
3b are provided protrudingly, and these feed claws 43b are connected to the passage.
Locking recess 17f of tray 16f with peg in Hf
It is designed to go inside and push the locking part 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.
6f as one group, and locking the locking portions 17af of the rearmost pegged trays 16f of these groups, the pegged trays 16f 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 explanation is 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 tray 16f with pegs may be locked and positioned using one predetermined feeding claw 43b of the feeding wheel 43.

In the above embodiment, an example in which the guide rails were arranged in an endless manner was explained, but the radius of the machine base
One end of the side and L side guide rails 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. Once connected, 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. In addition, each tray with pegs is moved in units of groups, with the trays with pegs located in each section of the guide rail divided into multiple sections being treated as one group. Even if there is a certain degree of manufacturing error, the cumulative error in peg position due to these manufacturing errors can be absorbed for each group, and this allows each peg to be stopped at a position facing the spindle with high precision. In addition to preventing the occurrence of pipe change errors, the permissible precision of the length dimension of the tray with pegs at the time of manufacturing can be lowered, and a large number of trays with pegs can be mass-produced at low cost by molding.

Effects of the Invention As described above, in the present invention, a locking recess that is concentric with the outer diameter of the tray is formed on the bottom surface of the tray with pegs, the inner surface of the locking recess is used as a locking portion, and the tray with pegs is Since the outer peripheral surface of is formed as the contact surface,
By locking the locking part on the inner surface of the locking recess of the tray with pegs and bringing the contact surface of the outer peripheral surface of the tray with pegs into contact with the contact surface of other trays with pegs, a large number of pegs can be attached. When the trays can be forcibly pressed and transferred and are transferred in a line along the path of the guide rail, the tray with pegs can be reliably moved even if fluff gets stuck between the guide rail and the tray with pegs, which is practical. In addition, the inner surface of the locking recess formed on the bottom of the tray with pegs is used as a locking part, and the outer circumferential surface of the tray with pegs is formed as an abutting surface for abutting against other trays with pegs, so that the tray with pegs can be attached easily. By locking the trays at approximately the same height as the contact surface, it is possible to move multiple trays with pegs all at once in a stable state without prying them, and even if the passage is curved, the trays with pegs can be moved with small force. It can be moved, reducing the energy needed to transport full and empty pipes. In addition, the inner surface of the locking recess formed on the bottom of the tray with pegs is used as the locking portion, and the outer diameter of the tray with pegs is set to the same size as the spindle pitch or half of the spindle pitch of the spinning machine. A large number of the trays with pegs are arranged in a line on the path of the guide rail arranged along the guide rail, and after the trays with pegs are moved by locking the locking parts of the trays with pegs at the ends, each tray with pegs is brought into contact. By intermittent stopping with the surfaces in contact with each other, the peg spacing of each pegged tray can be made equal to the spindle pitch or half of the spindle pitch, with the pegged tray always locked as a reference, and the pegged tray can be The tray moving device that moves intermittently allows each tray with pegs to be accurately positioned in the position corresponding to the spindle, simplifying the configuration of the tray moving device, and reducing equipment costs for empty tube conveyance. can. Furthermore, since the tray and the pegs are integrally molded from a synthetic resin material, trays with pegs can be mass-produced at low cost.
