Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a magazine delivery device in an automatic doffing machine used for doffing a spinning machine such as a spinning machine or a yarn twisting machine.

Conventional technology An automatic doffing machine used for doffing spinning machines such as spinning machines and twisting machines is equipped with a tip magazine at the rear and a bobbin magazine can be attached from the side of the machine. Some machines include a transport vehicle 3 that carries the spinning machine 1 and transports the spinning machine 2 from the side to the doffing platform. In a spinning machine such as a spinning machine or a twisting machine, the replacement machine 1 operates to remove a full bobbin from a spindle using a dotting device, and then insert an empty bobbin into the spindle using a bobbin supply bag and holder. Various types of bobbin supply devices have been proposed for the replacement machine 1, but in this type of bobbin supply device, a bobbin magazine mounting section is provided on the upper part of the machine base of the replacement machine B3! It is necessary to attach the bobbin magazine that was previously filled with empty bobbins to the same bobbin magazine mounting section. In addition, when the displacement machine 1 completes doffing for one side of the spinning machine 2, the cot magazine becomes full with the pipe yarn.
Before moving to the next doffing platform, it is necessary to replace the tip magazine with an empty one or to discharge the yarn in the tip magazine.

Conventionally, at the position where the replacement machine 1 has completed doffing one side of the spinner 1jlt 2 and returned to its original position, the operator manually pulls out the empty bobbin magazine from the bobbin magazine mounting section and places it on the floor or in a waiting manual pusher. The bobbin magazine is lowered onto the transport vehicle, and then the bobbin magazine filled with empty bobbins is lifted by hand and placed on the bobbin magazine mounting section. However, this full bobbin magazine weighs about 16k! Since there is a weight of +,
Even if it is possible to lift the machine relatively easily from the floor to knee or stomach height, lifting it to a higher position than where the bobbin magazine resting area is installed requires bending the elbows considerably. Not only was it extremely hard work, but there were also problems such as misloading. On the other hand, the number of threads stored in a cot magazine is generally around 200, whereas the number of threads stored in a general thread box is approximately 100 at most due to its handling. . Therefore, when storing the pipe yarn stored in the copp magazine in the pipe box, it is necessary to divide it into two parts and throw them into the pipe box. Therefore, the work of discharging the pipe yarn from the inside of the spin magazine is time-consuming and disadvantageous in that it reduces the operating efficiency of the automatic doffing machine and, by extension, the operating efficiency of the spinning machine.

In order to solve the above-mentioned problem, as shown in FIG. By placing the automatic guided vehicle 5 for transporting the tip magazine next to the corresponding position of the automatic doffing machine and moving the bobbin magazine 6 on the bobbin magazine holder 4, the delivery to the automatic guided vehicle 5 is carried out. There is a device in which the replacement 11!1 is installed on the bobbin magazine mounting portion and the tip magazine is replaced. However, even in the device that uses this automatic guided vehicle 5 to deliver and deliver bobbin magazines and tip magazines, the bobbin magazine and tip magazine are delivered manually, so it is not possible to make the automatic doffing machine unmanned. There wasn't.
