Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for inserting individual pipe threads when transporting the pipe threads from a spinning machine to a rewinding machine or other processing steps in the spinning process. A transport path is formed to move a large number of trays to be loaded along guide rails.
In cases where the yarn is inserted into the tray at a specific point in the middle and transferred, and the yarn is taken out from the tray at another point, whether or not the yarn is present in the tray past the yarn insertion section. This system is designed so that the empty trays that cannot be loaded with the yarn are returned to the insertion section by a simple means, and are particularly suitable for automatically feeding the yarn into the cot magazine of an automatic rewinding machine. It is.

[Conventional technology]

When transporting the pipe yarn from a spinning machine to a rewinding machine, for example, a tray is formed that has a base portion with a diameter larger than the outer diameter of the pipe yarn, and a pin for inserting the pipe yarn is provided in the center of the base. A method is used in which the trays are loosely mounted on a multi-frame guide rail and placed on a drive belt provided within the guide rail for conveyance. It has also been attempted to connect the tube yarn receiving section and the tube yarn supply section by using this conveying means. Attempts have also been made to transport them.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned tray-based conveyance device, since the trays are formed individually, it is difficult to specify the conveyance pitch. Furthermore, when inserting or removing the inserted tube yarn from this tray, it is necessary to hold the tray in a stopped state, even if only temporarily, so the tray pitch cannot be specified. Therefore, only when the movement of the tray is not restricted in any way, the tray moves individually with the belt,
Activation of a special stop restriction device, or the tray hits the preceding tray and stops, or it hits the preceding tray and moves at the same speed. Further, when the tray is stopped or at a slower speed than the belt, only the belt slides on the bottom surface of the tray to continue driving.

On the other hand, when inserting a tube into such a conveying device, the empty tray that has reached the specific tube insertion section is temporarily stopped from engaging, and the tube is inserted into the pin by inserting it.
This loading tray is moved again and conveyed to the tube supply and take-out section. In order to carry out such a pipe transport automatically, the pipe insertion section is required to have a function of monitoring whether or not the pipe has been loaded onto the tray. Possible monitoring means include a tube filler device, a detection device using a phototube, etc.
Such a detection device not only increases the equipment cost, but also requires the empty tray leading to the insertion section to be stopped and held until the feeding operation is performed again when the feeding tube is missing. Subsequent empty trays must be completely stopped. Furthermore, it is difficult to return an empty tray that has passed the insertion section to the insertion section. On the other hand, the transported pipe thread is intermittently supplied to the drop-in insertion section at a fixed pitch, but empty trays may occur and the empty tray may be fed as is to the pipe take-out section. In some cases, a device for detecting defective yarns and extracting them is provided following the yarn insertion section to form empty trays, and it becomes necessary to sort out the empty trays before reaching the yarn removal section.

[Means for solving problems]

Accordingly, the present invention provides a pipe transport device using a tray as described above, in which the transport path is divided into a pipe insertion circulation path provided in a pipe insertion/insertion device and a supply circulation path provided with a pipe take-out/supply device. These circulation paths are of a closed loop type for circulating the trays, and both connecting portions are configured to hold the trays almost horizontally and transfer them to each other, and the connecting portions are configured to transfer the trays loaded with pipe yarns. At the connection part, the empty tray is passed under and moved to the tube input/insertion device again, and the tube loading tray contacts a part of the outer peripheral surface of the tube to guide the loading tray to the supply circulation path side. It is constructed by providing a guide sorting regulating member.

[Function and Examples]

The present invention will be explained in detail below based on the drawings, which show an example of a specific implementation of the invention.
The present invention is not limited to these illustrated examples, but can be implemented in the same manner even if a part of the configuration or design is changed in accordance with the spirit described above and below.
FIG. 5 is a plan view showing the outline of the present invention's pipe transport device, in which a pipe insertion/insertion device 6, a pipe insertion circulation path 7 connected thereto, and a part of the pipe insertion circulation path 7 are connected. The supply circuit 8 is provided with a supply device 9 that extracts the pipe yarn from the tray and supplies it to another suitable device. It is a movable type that is installed in one or more passages 8 and moves along the circulation path 8, or it is a fixed type installed in a specific part, and the pipes are pulled out from the tray based on the pipe supply command. It is arranged to pick up and feed or to pull out all the tubes from the tray.

On the other hand, as shown in FIG. 3 (partial sectional view), the tray and conveyance path used in the present invention form a base portion 2b with a diameter larger than the outer diameter of the inserted tube 1, and have a stepped base portion 2b approximately in the center. Tray 2 provided with thread insertion pins 2a
Although it is preferable that the tray be shaped like a tray, a rectangular or oval shape conventionally known as a tray may also be used. The tray 2 is conveyed through U-shaped frames 3, 3.
It is recommended that a belt 4 having a round cross section is placed between the two, and that the belt 4 supports a part of the bottom surface of the tray 2, and the tray is transported by the drive of the belt 4. Then, as shown in FIG. 4 (illustrative sketch), the tube yarn 1a is dropped and inserted into the empty tray 2 which is held and stopped at a specific position on the guide rail 3, and the mooring of the tray 2 is released and the belt is inserted. Transfer by 4. The yarn-loaded tray 5 thus constructed is conveyed by the guide rail 3 and belt 4, and the feeding device 9 operates a fork-shaped wall-mounted arm on the stepped pin 2a of the tray 2 to pull up only the yarn. When the empty tray 2 is removed, the arm or other swinging member is operated to supply the pulled-up yarn, and the empty tray 2 runs along this guide rail again and is returned. On the other hand, the tube yarn input/insertion device 6 is configured to store a large number of tube yarns 1a in a hopper 6a provided at a high place, and to input each tube yarn using a guide trough or the like, and to place the tube yarns at the dropping position. An empty tray 2 provided with an opening/closing guide tube 6c and moored below the center thereof.
It is configured to insert a tube thread into the tube. The feeding/inserting device 6 pulls out and holds the thread of the pipe 1a, cuts the drawing thread to a certain length at the time of feeding and inserting the thread, and attaches the thread end to the pipe bobbin by suction airflow. It is recommended that the insertion device be equipped with a means for introducing the yarn into the top hole of the machine, and for feeding the yarn to an automatic rewinding machine, etc., it is recommended to use an insertion device equipped with a means for introducing the yarn into the top hole. It's convenient.

On the other hand, the above-described pipe insertion circulation path 7 and pipe supply circulation path 8 are both configured as closed-loop guide paths, and in the figure, the insertion circulation path 7 is suspended by pulleys 10 and 10a provided substantially horizontally. round belt 4
A guide rail 3 is provided along the line a, and a bypass path 3a is formed in the guide rail 3 in the insertion/insertion device 6, and an empty tray 2c in the insertion circulation path 7 is inserted by a tray feed lever 6b. They are now being sent to the department. Further, in the supply circulation path 8, a round belt 4b is stretched between a pulley 11 provided horizontally to the guide pulley 10 and a pulley 11a provided perpendicularly thereto at the connecting portion 7a with the insertion circulation path 7,
A guide rail is provided along this. In the illustrated example, the supply circulation path 8 is constructed with two stages, upper and lower.
The lower side serves as a return path for the empty tray 2c, and a chute 8a for sliding the upper empty tray downward is provided at the upper end, and this lower conveyance path is connected to the insertion circulation path 7. The empty tray is used as a rising guide rail 8b. That is, the supply circulation path 8 includes the pulleys 11, 11a and the guide pulley 1.
A guide path is formed by suspending a round belt 4b between 1b and 11c. If necessary, a separately driven round belt or other lifting drive means may be provided along with the rising guide rail 8b. Since such a circulation conveyance path is a round belt, it can be freely designed, but it can also be constructed by using flat belts, V-shaped belts, roller conveyors, etc. that have been conventionally used for tray movement, either as they are or by appropriately combining them. You may.

On the other hand, in the pipe yarn conveying device configured in this way, it is not guaranteed that the tray 2 taken out from the pipe input/insertion device 6 is the loading tray 5, and there is a risk of omission of the input pipe yarn, insertion error, malfunction, etc. Therefore, the empty tray may be taken out, or the loading/inserting device 6 may
If a defective yarn detection and discharge device is provided on the tray take-out side, an empty tray 2c will exist on the loaded tray transfer side of the insertion circulation path 7. It is difficult to take out such an empty tray 2c freely, and a special detection device and removal device are required, as well as a means to bypass the empty tray that has been taken out again to the return side of the insertion circulation path. It is also difficult in terms of equipment. Therefore, in the present invention, at the connection between the insertion circulation path 7 and the supply circulation path 8, only the loaded trays are transferred to the supply circulation path 8, and the empty trays are returned to the insertion circulation path 7 side together with the empty trays in the supply circulation path 8. This includes providing a sorting regulating member at the connection part that automatically sorts and transfers the articles. That is, as shown in FIG. 1 (partially enlarged plan view of FIG. 5) and FIG. 2 (left side view of FIG. 1), the pulley 10 of the round belt 4a constituting the insertion circulation path 7 and the supply circulation path The pulleys 11 of the round belt 4b constituting the belt 8 are provided close to each other almost horizontally and are each driven to rotate in the direction of the arrow. A regulating member 12 is provided at the tray transfer portion on the side of the insertion circulation path 7 in the connecting portion 7a, which contacts the outer surface of the loaded pipe yarn and allows the empty tray 2c to pass through. Although the figure shows that the regulating member 12 is made of a curved plate and is installed on the guide rail 3 on the side of the insertion circulation path 7 via a bracket 12a, it may be freely provided via other parts. can. Further, the regulating member 12 is not limited to a plate material but may be a rod-shaped or perforated plate material to have a smooth contact surface. In order to make these guides more reliable, if the guide plate 13 is formed as shown in the figure and provided on the supply circulation path 8 side,
The empty tray 2c can be reliably guided to the return side of the insertion circulation path 7, and the empty tray 2c returned from the supply circulation path 8 side can be reliably guided to the insertion circulation path 7 side. The present invention can also be satisfied with only 12.

〔Effect of the invention〕

Since the yarn conveying device of the present invention is configured as described above,
The tube yarn can be automatically conveyed and supplied while sorting the tube yarn loaded tray and the empty tray by extremely simple means, and the empty tray can be smoothly transferred again to the tube yarn input insertion section. In addition, the pipe thread take-out device in the supply circulation path does not require a mounted pipe thread detection device, and the take-out operation can be performed simply by detecting the tray, which simplifies the mechanism.
