Description

Detailed Description of the Invention Technical Field The present invention relates to a spinning machine or a yarn twisting machine, which is equipped with a peg conveyor below a spindle row, when the spinning machine or the like is fully loaded. It runs, and 1 full tube on the spindle and 1 empty tube prepared on the peg conveyor.
This article relates to a tube change method and a tube change machine in spinning machines and the like that continuously change tubes.

PRIOR ART AND PROBLEMS Conventionally, a peg conveyor is attached below the spindle row of a spinning machine, a yarn twisting machine, etc. The running tube changing machine is equipped with a full tube gripping device and an empty tube gripping device that move back and forth and move up and down, and these two sets of tube gripping devices separate the full tubes on the spindle and the empty tubes prepared on the peg conveyor. A pipe changer that replaced multiple pipes at the same time was published in 1976.
This method has already been proposed in Japanese Patent Publication No. 8136, Japanese Patent Publication No. 56-20368, Japanese Patent Publication No. 58-58447, etc. However, since this conventional pipe changer is an intermittent movement type pipe changer that alternately performs the movement of the pipe changer and the pipe change operation, there is a limit to its pipe change speed. In addition, such an intermittent movement type tube changing machine changes tubes by simultaneously gripping full tubes and empty tubes with multiple tube gripping tools, so the number of spindles of the spinning frame, spindle pitch, etc. It was not possible to use the same pipe changing machine for machines with different specifications such as lifts, and it was necessary to change the design each time depending on the conditions (specifications) of the spinning machine. Furthermore, such an intermittent moving type pipe changer is 9. 8 to 1 by one pipe change operation to shorten pipe change time.
It is designed to change the pipes between two full pipes and an empty pipe, which has the disadvantage that the pipe changer becomes large as a result.

On the other hand, Japanese Patent Publication No. 41-11663 discloses that a large number of full-tube gripping tools are installed on the running body of an automatic tube changer that runs between the spindle rail of a spinning machine such as a draw twister and a bedding conveyor placed in front of the spindle rail of a spinning machine such as a draw twister. A full tube extraction means and an empty tube extraction means are provided, each consisting of two sets of endless belts equipped with an empty tube gripper and an empty tube gripper, and the endless belts are set relative to the advancing speed of the automatic tube changer and the revolving speed of the peg conveyor. An automatic pipe change method is to rotate the pipe so that the speed is zero on both the spindle rail side and the peg conveyor side, transfer the full pipe extracted from the spindle side to the peg conveyor, and insert the empty pipe on the peg conveyor into the spindle. Already proposed. However, the automatic tube changer for carrying out this automatic tube change method has to completely adjust the rotational speed of the full tube extraction means and the empty tube extraction means, which are composed of endless bodies, to the traveling speed of the traveling body and the movement speed of the peg conveyor. If they are not synchronized, the relative positions of the spindle, peg, and tube gripping tool will be misaligned, resulting in breakage or damage to the spindle, bobbin, or tube gripping tool during tube change, and damage to the endless body, running body, and peg conveyor. The disadvantage was that speed control was extremely difficult. In addition, since this automatic tube changer is equipped with a large number of tube gripping tools on its endless body, it is difficult to use the tube gripping tools for machines with different specifications such as the spindle pitch and lift of the spinning machine. The drawback was that the design of the cams, lifting cams, etc. had to be changed each time. Furthermore, in the case of this automatic pipe change method, since the peg conveyor is placed in front of the spindle rail, the long peg conveyor that spans the entire length of the machine is moved to the floor side where it does not interfere with work except when changing pipes. Not only does this complicate the peg conveyor, but also the peg conveyor is located in front of the spindle rail when empty tubes are supplied and full tubes are taken out during machine operation, and the peg conveyor is located in front of the spindle rail during this time. This had the disadvantage of interfering with work.

In addition, in the conventional tube changer, a tube changer equipped with a full tube storage box and an empty tube supply box is run continuously along the front of the spindle row of a spinning machine, and as it runs, the tube changer is equipped with a full tube storage box and an empty tube supply box. The full tube on the spindle is pulled up using lifting means such as a tube lifting plate and rotating rolls installed on the spindle.

The extracted full tubes are stored in the onboard full tube storage box via a chute, etc., and the empty tubes in the empty tube supply box are supplied via the chute to the spindle that pulled up the full tubes for tube replacement. However, because these conventional tube changers are equipped with a full tube storage box and an empty tube supply box, the tube changer becomes large and has a problem when the tube is full. It requires complicated equipment for storing tubes and taking out empty tubes, and in addition, each time a tube is replaced, a full tube storage box must be replaced with an empty full tube storage box, and the empty tube storage box must be replaced with an empty full tube storage box. It is necessary to replace the tube supply box with an empty tube supply box filled with empty tubes in advance, and in addition, the large and heavy full tube storage box containing many full tubes must be automatically transported to the next process. The disadvantage was that it required a lot of effort.

Outline and Purpose The present invention was devised as a result of various studies in view of the drawbacks of the prior art. The machine runs along the row of spindles from one end of the machine to the other, and continuously runs a tube changing machine that automatically switches between full tubes on the spindle and empty tubes on the peg conveyor. The tube changing machine is equipped with a single-weight lifting device for pulling out full tubes on the spindle in one size, and a single-weight lifting device for pulling out empty tubes on the pipe conveyor in one size. Equipped with a tube device, behind the full tube unloading device, there is a single-spindle empty tube that inserts the empty tube after being pulled out into the spindle after pulling out the full tube by one inch as the tube changing machine runs. An insertion device is installed, and behind the empty tube removal device, there is a single-spindle insertion device that inserts full tubes after being pulled out into the conveyor belt after pulling out the empty tubes. A full tube insertion device is provided, and a full tube transfer device that transfers the full tubes pulled up from the spindle to the full tube insertion device, and a pipe transfer device that transfers the empty tubes pulled up from the peg conveyor to the empty tube insertion device. It is characterized by being equipped with a pipe transfer device, and as the pipe changing machine runs, the pipes are changed continuously between full pipes on the spindle and empty pipes on the conveyor. Pipe change time is shortened compared to conventional intermittent transfer type pipe changing machines that change full and empty pipes between conveyors.
Moreover, even if there are slight differences in specifications such as the number of spindles, spindle pitch, lift, etc. of spinning machines, there is no need to make design changes each time as in the past, and the same pipe changer can handle them. It is possible to change the pipes of spinning machines with different specifications such as the number of spindles, spindle pitch, and lift. Furthermore, the structure is simple and the pipe changer can be made smaller. It is an object of the present invention to provide a tube changer method and tube changer for spinning machines, etc., which eliminates the need for automatic conveyance of full and empty tubes, and eliminates the drawbacks of the prior art.

Equipped with a pipe transfer device, as the pipe changing machine runs, the full pipe on the spindle and the empty pipe on the peg conveyor are continuously changed by one tree. When changing full and empty pipes between peg conveyors.

Compared to the conventional intermittent movement type pipe changer, the pipe change time is shortened, and even if there are some differences in specifications such as the number of spindles, spindle pitch, lift, etc. of the spinning machine, it can be used as before. There is no need to change the design each time, and the same pipe changer can be used to change the pipes of spinning machines with different numbers of spindles, spindle pitches, and lifts. Moreover, since it does not include a full pipe storage box or an empty pipe supply box, the structure of the pipe changer is simple and compact, and
This has the feature that automatic conveyance of empty tubes is also facilitated.
