Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer driving device for a bobbin carrier which applies a propulsive force to a carrier for carrying a bobbin between a spinning machine and a spinning machine.

[0002]

2. Description of the Related Art In a spinning factory, it is necessary to convey a full roving bobbin produced by a roving machine to a spinning machine side and an empty roving bobbin used in the spinning machine to the roving machine side. For example, in JP-A-62-104934, etc.,
By laying a carrier rail between the roving frame and the spinning frame, and pulling the carrier by a carrier machine (towing vehicle) while suspending a large number of bobbins on the carrier arranged so that it can travel on the carrier rail. The bobbin is being transported.

However, according to this bobbin carrying device, since the carrying machine is expensive, the equipment cost of the bobbin carrying device rises, and the carrier does not start traveling until the carrying machine arrives. There was a problem that wasted waiting time occurred.

In order to solve this problem, for example, Japanese Patent Publication No. 63-29016 and Japanese Patent Publication No. 63-61418 disclose a bobbin transfer device as shown in FIGS. ing.

As shown in FIG. 9, a conveyor rail 53 is provided between the roving frame stand 51 and the spinning frame stand 52. The transport rail 53 includes a main transport rail 53a extending perpendicularly to the longitudinal direction of the machine bases 51 and 52, and a main transport rail 5.
It is composed of a branching and conveying rail 53b that branches from 3a and extends along the machine bases 51 and 52. On the transport rail 53, a transport body (transport tool string) suspending a bobbin hanger is provided so as to be able to travel along the transport rail 53 via a traveling roller (neither is shown). A transfer device 54 is provided on the transfer rail 53 at predetermined intervals, and the transfer body is moved by the transfer device 54.
It is configured to travel on the transport rail 53 by obtaining the driving force from the.

As shown in FIG. 8, the transfer device 54 is provided with a pair of rotating discs 56 and 57 which are opposed to each other with a passage path of a link-coupled substrate 55 forming a carrier interposed therebetween. The rotating disk 56 is arranged so as to be able to contact the side surface of the substrate 55, and is operatively connected to the drive shaft of a motor 60 (shown in FIG. 9) via conical friction wheels 58, 59 and the like. The rotating disc 57 is biased by the spring 61 toward the side closer to the rotating disc 56, and is positionally regulated so that a space narrower than the width of the substrate 55 can be held from the rotating disc 56.

The motor 60 is driven by the carrier, and the substrate 55 is inserted so as to widen the gap between the rotating discs 56 and 57 in the rotating state. Then, the substrate 55, which receives the pressing force from the rotating disc 57 based on the urging force of the spring 61, is pressed against the rotating disc 56 in the rotating state, so that the propulsive force in the tangential direction is generated from the rotating disc 56. I'm supposed to get it.

According to this bobbin carrying device, since the carrying machine is unnecessary, the equipment cost of the bobbin carrying device is suppressed, and the wasteful waiting time by the carrying machine is eliminated to improve the efficiency of the bobbin carrying work. You can

[0009]

By the way, the number of bobbins hung on the carrier is usually set in accordance with the number of spindles of the roving frame and the spinning frame. In recent years, the number of bobbins to be conveyed at one time by the conveyor tends to increase with the increase in the number of spindles of the rough spinning machine and the fine spinning machine. Therefore, the carrier for suspending the full roving bobbin has a considerable weight.

According to the transfer device 54 of FIG. 8, the substrate 55 of the carrier is pressed by the rotating disk 57 to be rotated 56.
Since it only abuts on the outer peripheral surface, the contact area is quite small. Therefore, when the weight of the carrier increases and the load increases, slippage occurs due to the small contact area between the substrate 55 and the rotating disk 56 of the carrier, and a locally idle state occurs. There was a risk of doing it. In particular, a large load is applied at the start of traveling of the transporting body in the stopped state, so that slippage is more likely to occur between the substrate 55 and the rotating disk 56, and smooth starting becomes difficult. Further, there may be a case where it becomes difficult to travel the transport body due to a completely idle state.

Therefore, when the transfer device 54 shown in FIG. 8 is used under such a condition, the transfer device 54 per unit is designed so that the carrier body simultaneously receives the propulsive force from the plurality of transfer devices 54. The load should be reduced. But,
For that purpose, there is a problem that the installation interval of the transfer devices 54 must be narrowed to increase the number of installations. Further, a method of increasing the urging force of the spring 61 to increase the contact pressure between the substrate 55 and the rotating disk 56 to suppress slippage can be considered, but there is a limit to that.

Further, when slippage occurs between the substrate 55 and the rotary disc 56, the slippage causes severe wear of the rotary disc 56. Then, as the wear of the rotary disc 56 progresses, the gap between the rotary discs 56 and 57 increases, and the gripping force for gripping the substrate 55 becomes smaller, so that a situation in which slippage is more likely to occur occurs.

The present invention has been made to solve the above problems, and its object is to transfer a driving force for propelling the bobbin from a transfer drive device to a transfer body without fail. An object is to provide a body transfer drive device.

[0019]

According to the first aspect of the invention, therefore, the carrier is provided with bobbins mounted on the bobbin hangers suspended from a plurality of link members connected in series, and provided on the carrier rail at intervals shorter than that of the carrier. Propulsive force is obtained from the transfer driving device thus obtained, and travels on the transport rail via the travel roller. In each transfer driving device, the link member of the carrier is a driving belt that is hooked on a pair of pulleys and is rotationally driven by a driving means,
The link member is clamped and held by the biasing force of the biasing means between the link member and the pressing member that allows the transport rail to move in the longitudinal direction. Therefore, the driving force on the drive belt side is transmitted to the link member via the contact surface between the drive belt and the link member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment embodying the present invention will now be described with reference to FIGS.
It will be described with reference to FIG. As shown in FIG. 6, a carrier 3 having a plurality of bobbin hangers 2 is provided on the carrier rail 1 so as to be capable of traveling via traveling rollers 4. Carrier 3
Is mounted on the bobbin hanger 2 with the bobbin B in the fully roving state (state of FIG. 6) or in the empty roving state and travels on the transport rail 1.

A plurality of link members 5 constituting the carrier 3
Are connected by a pin 7 via a connecting member 6 such that they can be bent and moved in a horizontal plane (in a plane orthogonal to the plane of FIG. 6). The connecting member 6 is formed so as to have a thickness that is the same as the thickness of the link member 5 in the width direction (the direction orthogonal to the paper surface of FIG. 6) with respect to the gap between the link members 5. Therefore, the link member 5 has a substantially uniform width over the entire length of the link member 5 even at the position corresponding to the link member 6. Six bobbin hangers 2 are suspended from each link member 5 so as to be arranged at equal intervals over the entire length of the carrier 3.

As shown in FIG. 3, the conveying rail 1 has a substantially U-shaped cross-section whose lower side is open, and is bent and formed horizontally so that both sides are closed inward under the cross-section. The traveling roller 4 rolls on the upper surface of the barrel. A pair of left and right traveling rollers 4 are provided in the width direction of the transport rail 1. A support shaft 8 that rotatably supports the traveling roller 4 is axially fixed to a support member 9, and is pivotable with respect to the support rod portion 9a at the lower end of a support rod portion 9a extending downward from the support member 9. Each link member 5 is fastened and fixed in the inserted state. Each link member 5 is suspended and supported by the support rod portion 9a at two positions near both ends thereof.

A pair of front and rear guide rollers 10 are provided on the support member 9.
Are rotatably arranged in a horizontal plane between the inner surfaces of the lower end of the transport rail 1 having a narrow space. By guiding the guide roller 10 to the inner surface of the lower end of the transport rail 1, the steering direction of the traveling roller 4 is changed so as to follow the route of the transport rail 1.

A restricting portion 9b having a diameter larger than the opening width of the transport rail 1 is formed on the supporting rod portion 9a so as to project in the horizontal direction. The rising deviation of the carrier 3 is restricted.

1 to 5 are provided on the transport rail 1 at predetermined intervals shorter than the entire length of the transport body 3. The carrier 3 is configured to travel on the carrier rail 1 by receiving a propulsive force from each transfer driving device 11.

As shown in FIGS. 1 to 5, the transfer driving device 1
Reference numeral 1 denotes a belt 14 having a V-shaped cross section as a drive belt which is hung on a pair of pulleys 12 and 13 and rotationally driven in a horizontal plane.
And two rollers 15 and 16 as driven rollers which are arranged opposite to the outer peripheral surface of the belt 14 with the movement path of the link member 5 of the carrier 3 interposed therebetween.

Each pulley 12, 13 has a bearing 17, 1
8 are fastened and fixed to the lower ends of the rotary shafts 19 and 20 rotatably supported by 8, respectively. A motor (geared motor) 22 having a gear box 22a shown in FIGS. 3 to 5 is installed at a position corresponding to the bearing 18 on the upper surface of a support plate 21 (not shown in FIG. 5) that suspends and supports the transport rail 1. Has been done. The motor 22 can rotate forward and backward, and a drive shaft (not shown) of the motor 22 is operatively connected to the rotary shaft 20 via a gear train (not shown) in the gear box 22a. Further, the bearings 17 and 18 are fixed to the support plate 21, and the fixing position of only the bearing 17 can be changed so that the tension of the belt 14 can be adjusted.

On the other hand, the rollers 15 and 16 are constituted by the rotary shafts 23 and 2
4 are fastened and fixed to the lower ends of the rotating shafts 23, 24
The bearings 25 and 26 that rotatably support are fixed to two arm levers 28 and 29 that are rotatably provided with respect to a support shaft 27 fixed to the support plate 21. The arm levers 28 and 29 extend horizontally from the vicinity of the center of the upper surface of the support portions 28a and 29a and the support portions 28a and 29a that extend horizontally while the one end side is supported by the support shaft 27. In addition, it has arms 28b and 29b that are bent substantially at right angles to the rear side (right side in FIG. 3) orthogonal to the longitudinal direction of the support portions 28a and 29a and extend in an L shape.

Each of the bearings 25 and 26 has a support portion 28a,
29a are fixed to the lower surface of the end opposite to the support shaft 27. Arm 28 of arm lever 28, 29
b and 29b are a pair of insertion holes 3 formed in the support plate 21.
It is arranged in a state of extending to the upper side of the support plate 21 via 0.

Cylindrical locking members 31 are respectively fixed to the upper surfaces of the rear ends of the arms 28b and 29b, and springs 32 are stretched on the respective locking members 31 in a state of locking both ends thereof. Arm levers 28, 29 by spring 32
Are urged to rotate so that their rear ends approach each other, and the rollers 15 and 16 are urged to approach the belt 14 side via the arm levers 28 and 29 that are urged to rotate. The arm levers 28, 29 are positionally regulated on the urging direction side by contact with the restriction pin 33 on the support plate 21, and when the arm portions 28b, 29b are in contact with the restriction pin 33, as shown in FIG. As shown in FIG. 2, the rollers 15, 1
6 is arranged to face the outer peripheral surface of the belt 14 with a distance slightly shorter than the width of the link member 5 of the carrier 3.

As shown in FIGS. 1 to 3, on the support plate 21, two proximity sensors 34 and 35 are provided on each arm 28b and 29b.
The rear end face is arranged so that it can be detected. Proximity sensor 3
Numerals 4 and 35 detect the rear end face of the arms 28b and 29b in contact with the regulation pin 33 and turn them off, and the link member 5 resists the urging force of the spring 32 between the rollers 15 and 16 and the belt 14. Then, the arms 28b and 29b, which are invaded so as to spread out and are in contact with each other, are set to be turned on when the arm portions 28b and 29b are separated from the regulation pin 33. The motor 22 is driven when at least one of the two proximity sensors 34 and 35 is on. At this time, the forward / reverse rotation direction of the motor 22 is controlled by the order in which both the proximity sensors 34 and 35 are turned on. When the proximity sensor 34 is turned on first, the motor 22 is driven to rotate normally and the pulley 13 is moved to the position A in FIG.
When the proximity sensor 35 is turned on first, the pulley 13 rotates in the direction of the arrow, and is driven in the reverse direction to rotate the pulley 13 in the direction of the arrow B. In the transfer driving device 11 arranged at the predetermined stop position of the carrier 3, the drive of the motor 22 is controlled to be stopped by a control device (not shown) regardless of the operating states of the proximity sensors 34 and 35.

Further, the support plate 21 constituting the transport rail 1
A cover 36 extending downward is fixed to a portion corresponding to the transfer driving device 11, and the supporting plate 2 of the transfer driving device 11 is fixed to the cover 36.
A portion below 1 is covered with a cover 36.

Next, the operation of the bobbin carrying device constructed as described above will be described. The carrier 3 conveys the full roving bobbin B produced by the roving machine to the spinning machine and the empty roving bobbin B used in the spinning machine to the roving machine side. In the standby state before the conveyance body 3 arrives, as shown in FIGS. 1 and 2, the rollers 15 and 16 of the transfer drive device 11 cause the spring 3 to move.
The belt 14 is urged toward the side closer to the belt 14 by the urging force of 2 and is separated by a distance slightly shorter than the width of the link member 5.
It will be in a state of being opposed to. In this state, the proximity sensors 34 and 35 detect the rear end surfaces of the arm portions 28b and 29b and are turned off, so that the motor 22 is stopped.

On the roving frame side, the full bobbin bobbin B produced by the roving frame is mounted on the bobbin hanger 2 of the carrier 3 from which the empty bobbin B used in the spinning frame has been removed. At this time,
The transfer driving device 11 arranged at the position corresponding to the mounting position of the full roving bobbins B is stop-controlled by the control device, and when the mounting of the full roving bobbins B to all the bobbin hangers 2 is completed, the stop control is performed. The transfer drive device 1 is released.
The carrier 3 which obtains a propulsive force by driving 1 and suspends the full roving bobbin B starts traveling on the carrier rail 1 toward a predetermined spinning machine.

At the start of this traveling, the side of the carrier 3 corresponding to the transfer driving device 11 of the link member 5 is clamped by the rollers 15, 16 and the belt 14 in the transfer driving device 11 from both sides. In this state, the motor 22 is driven from this state and the belt 14 is rotationally driven. At this time, the link member 5 comes into contact with the belt 14 on a surface having a length substantially equal to the distance between the axes of the pulleys 12 and 13, and the contact area is sufficiently secured. Even when the bobbin B is suspended and the load is relatively applied, the rotational force of the belt 14 is reliably transmitted to the link member 5 without slippage. Therefore, the carrier 3 starts traveling smoothly.

Before the rear end of the carrier 3 (the end on the side of the roving frame) is disengaged from the transfer driving device 11, the forward end of the carrier 3 in the advancing direction is moved to the next transfer driving device 11. To reach.
At this time, when the transport body advances to the next transfer driving device 11 from the left direction in FIGS. 1, 2 and 4, for example, the tip of the link member 5 first causes a gap between the belt 14 and the roller 15. The arm lever 28 is rotated based on the displacement of the roller 15 caused by the invasion so that the arm portion 28b which is in contact with the roller is separated from the regulation pin 33. As a result, the proximity sensor 34
Is turned on, the motor 22 is driven to rotate normally, and the pulley 13 is moved to the position shown in FIG.
The belt 14 rotates in the direction of arrow A in FIG.

The front end of the carrier 3 is the front transfer drive device 11
In addition to the propulsive force from the
Propulsive force is obtained from No. 4 to advance inside the transfer driving device 11 to the roller 16 on the destination side, and the link member 5 comes into contact with the entire one surface of the belt 14. At least after this state, the carrier 3 leaves the engagement with the previous transfer drive device 11. Therefore, the carrier 3 always engages with one of the transfer driving devices 11 in a state where the link member 5 is in contact with the entire one surface of the belt 14, and thus each transfer driving device 1
The propelling force is surely obtained from 1 to travel on the transport rail 1.
Therefore, slippage does not occur between the belt 14 and the link member 5 even when the transport body 3 is running, and the rotational force of the belt 14 is reliably transmitted to the link member 5 as a propulsive force.

On the spinning machine side, the full roving bobbins B conveyed and the used empty roving bobbins B are exchanged by an automatic machine such as a roving changer to suspend a large number of empty roving bobbins B. The carrier 3 travels on the carrier rail 1 toward the roving frame.
At this time, the carrier 3 enters the transfer drive device 11 provided on the carrier rail 1 from the right side in FIGS. 1, 2 and 4, which is on the opposite side to the carrier roving bobbin B when it is carried. To do.

The leading end of the link member 5 on the traveling side is the belt 1.
4 and the roller 16 are pushed in so as to push away the roller 16 urged by the spring 32, and the proximity sensor 35 detects that the arm 29b is separated from the regulating pin 33 due to the displacement of the roller 16 and the motor 22 is driven. Reverse drive is started. Then, the pulley 13 rotates in the direction of arrow B in FIG. 1, and the belt 14 rotates in the counterclockwise direction in FIG.
Therefore, the carrier 3 travels on the carrier rail 1 by receiving the propulsive force in the traveling direction from the belt 14 via the link member 5.

As described above in detail, according to the bobbin transporting apparatus of this embodiment, the rotational force of the belt 14 is applied to the link member 5 by bringing the outer peripheral surfaces of the belt 14 mounted on the pair of pulleys 12 and 13 into contact with each other. Since it is configured to transmit power, the contact area between the belt 14 that is the power transmission source and the link member 5 that is the power transmission destination is sufficiently wide. Therefore, the rotational force of the belt 14 can be reliably transmitted to the link member 5 side without slippage between the power transmission source and the power transmission destination.

Even if the number of bobbins to be conveyed per one time increases and the load applied to the transfer driving device 11 increases due to the increase in the number of fine spinning machines and rough spinning machines, the space between the belt 14 and the link member 5 is increased. Since a sufficient contact area is secured, the power of the belt 14 can be reliably transmitted to the link member 5 on the carrier side without slipping. Therefore, the heavy carrier 3 can be reliably transferred. In particular, a relatively large propulsive force is required at the time of starting the carrier 3, but since the rotational force from the transfer drive device 11 side is efficiently transmitted to the link member 5, it is possible to support a large number of machine bases. can do.

Further, the arrival of the carrier 3 to the transfer driving device 11 is detected by the proximity sensors 34 and 35 as displacement of the rollers 15 and 16 which push the link member 5 away, and the motor 22 is driven only when necessary. The power consumption of the motor 22 can be reduced. In addition, the transport rail 1
Two rollers 1 arranged on both sides in the longitudinal direction with respect to
Since the two proximity sensors 34 and 35 capable of respectively detecting the displacements of 5 and 16 are provided, the moving direction of the carrier 3 is determined based on the operation order of the proximity sensors 34 and 35, and the motor is adjusted to match the moving direction. The direction of rotation of 22 can be controlled in forward and reverse directions.

Further, when slippage occurs, wear on the contact surface becomes severe, but according to the transfer drive device 11 of the present embodiment, slippage does not occur easily, and therefore the belt 14 does not wear out easily.
The present invention is not limited to the above embodiments, and may be configured as follows, for example, without departing from the spirit of the invention.

(1) As shown in FIG. 7, the pulleys 12, 1
In the state in which one roller 37 is biased toward the belt side at a position corresponding to the approximate center between the shaft centers of the pulleys 12 and 13 with respect to the belt 14 mounted on the belt 14, the link member 5 is attached to the belt 14. It is also possible to have a structure in which they are opposed to each other with a gap shorter than the width thereof. In FIG. 7, the roller 37 is arranged so that the distance to the belt 14 can be changed via the rotation lever 38, and the rotation lever 38 urged toward the belt 14 by the spring 39 is regulated by contact with the regulation pin 40. As a result, the roller 37 is held in a state of being separated from the belt 14 by a predetermined distance. This structure also allows the smooth entry of the link member 5 and allows the roller 37
The link member 5 can be pressed against the belt 14 by the urging force of the belt 14 toward the belt 14. Therefore, the number of the rollers 37 as the driven rollers is one, so that the structure of the transfer driving device 11 is simplified.

(2) The side surface of the link member 5 may be sandwiched by the drive belts from both sides. With this configuration, it is possible to secure a wider contact area for transmitting power. In this case, the urging of the drive belt may be one or both. The power of both drive belts may be shared by one motor 22 or may be independent of each motor 22.

(3) A plurality of transfer driving devices 11 may be driven by a common motor, for example, via a power transmission mechanism between the transfer driving devices 11. (4) The positions of the proximity sensors 34 and 35 can be appropriately changed to appropriate positions where the arrival of the link member 5 can be detected. For example, a sensor that directly detects the link member 5 immediately before reaching the transfer driving device may be provided, and the belt 14 may be rotationally driven immediately before the link member 5 enters the transfer driving device 11. With this configuration, the link member 4 smoothly enters between the rollers 15 and 16 and the belt 14, and the load when the link member 5 enters can be suppressed to a small level. Further, the sensor may be another non-contact sensor such as an infrared sensor, or may be changed to a contact sensor. For example, the arm lever 2 with a limit switch
It may be configured to detect the displacements of 8 and 29.

(5) The shape of both ends of the link member 5 in the entire length of the carrier 3 may be formed, for example, in a pointed curved shape so that the link member 5 can easily enter between the rollers 15 and 16 and the belt 14. With this configuration, it is possible to reduce the load that the link member 5 receives when entering the transfer drive device 11.

(6) The rollers 15 and 16 are of a fixed type,
The belt 14 side may be movable. To move the belt 14, the motor 22 may be moved. (7) The belt 14 may be a timing belt. The slip between the pulleys 12 and 13 and the belt 14 can be suppressed.

(8) A tension pulley may be provided between the pulleys 12 and 13 for holding the tension of the belt 14. The invention grasped from the above-mentioned embodiment and not described in the scope of claims is described below together with its effect.

(A) In claim 1, the pressing means is a second drive belt which is hung on a pair of pulleys and rotationally driven by the drive means. With this configuration, it is possible to secure a wider contact area to which the driving force is transmitted, and it is possible to further suppress slippage.

[0055]

As described above in detail, according to the first and second aspects of the present invention, the intermediate portion for transmitting the driving force to the link member of the carrier is a driving belt having a pair of pulleys. Since the contact area with the link member is ensured to be wide, it is possible to suppress the slippage with the link member during the transmission of the driving force and to reliably transmit the driving force to the link member side. Play.

According to the third aspect of the present invention, the propulsive force is applied to the link member by detecting the displacement of the driven roller when the link member of the transport body enters between the drive belt and the driven roller. Since the driving means is driven only when it is necessary to do so, there is an excellent effect that the power consumption of the driving means can be reduced.

According to the invention as set forth in claim 4, since two detectors for individually detecting the displacements of the two driven rollers at the time when the link member of the carrier is intruded are provided, the operation sequence of each detector From this difference, it is possible to recognize the traveling direction of the carrier and control the rotation direction of the drive belt in accordance with the traveling direction.

According to the invention described in claim 5, since only one driven roller is required, there is an excellent effect that the transfer driving device can have a simple structure.
