Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a core tube recovery device for bobbin supply / discharge equipment. It is important to efficiently replenish the actual bobbin to the winder device with many winders installed and to collect used empty trays without interruption in order to improve the operation rate of the winder device. Therefore, a replenishment station that attaches a bobbin to the collected empty tray and sends it out as an actual bobbin is provided, and an actual bobbin replenishment path and an empty tray recovery path are individually provided between the replenishment station and the winder device to make an empty loop. It has been attempted to continuously supply and recover while circulating the tray and the actual bobbin. In the above equipment, when the used empty tray is discharged from the winder, the core tube that has wound the thread is still attached to the peg of the empty tray. If this core tube is not removed before entering the refill station, the thread-wound core tube at the refill station (ie bobbin formed in corn or cheese) cannot be mounted on an empty tray peg. The present invention relates to a core tube recovery device used in such a case.

[0002]

[Prior art]

 In some cases, the core tube has been collected manually, but the efficiency is low and the operation rate of the winder cannot be increased. In the case of automation, the first thing that can be considered is an automated handling device that uses a robot, etc., but if this is used, the equipment cost will be extremely high.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and an object thereof is to provide a core tube recovery device which can sufficiently follow the improvement in the operating rate of a winder and can be realized at an extremely low facility cost.

[0004]

[Means for Solving the Problems] The core tube recovery device of the present invention is a replenishment station for mounting a bobbin on a recovered empty tray and sending it out as an actual bobbin, and winding a thread from the supplied actual bobbin and using it. In a bobbin supply / discharge facility in which an actual bobbin replenishing path and an empty tray collecting path are provided between the empty tray collecting path and the winder device, a core tube for taking out a core tube from the empty tray in the middle of the empty tray collecting path. A recovery device is installed, and the core tube recovery device consists of two guide rails for supporting the empty tray and pushing the front tray with the succeeding tray to convey it. The two guide rails are parallel to each other. It is characterized by being spirally twisted one or more turns along the traveling direction of the empty tray while maintaining such a state.

[0005]

[Action]

 In the present invention, when the empty tray is pushed on the guide rail, the guide rail is twisted in a spiral shape, so that the peg of the empty tray will face downward, and the core tube will naturally move due to the action of gravity at that time. To fall. Then, each time the empty tray is pushed, the core tubes drop in sequence, so that the core tubes can be automatically taken out without any trouble. Also, since two guide rails are sufficient as parts, the equipment cost is extremely low.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a conceptual diagram of a bobbin supplying / discharging equipment to which the core tube collecting device A of the present invention is applied. W is a winder device in which a large number of winders are arranged in parallel, S is a replenishing station, and the space between these is actual. The bobbin supply path B and the empty tray recovery path C are connected to each other, and the core tube recovery device A is installed in the middle of the empty tray recovery path C. The replenishment station S is a facility that collects the empty tray T1 and sends out an actual bobbin tray T2 in which an actual bobbin b (a cheese or a corn having a thread wound around a core tube a) is attached to the peg 1. . The winder device W receives the supply of the actual bobbin b, thereby winding the yarn on a large package or the like, and when the winding is completed, the empty tray T3 is discharged to the former collecting path C1. The empty tray T3 at this stage still has the core tube a attached. The core tube a of this empty tray T3 is recovered by the core tube recovery device A, and the empty tray T1 from which the core tube a has been removed is sent to the subsequent recovery path C2 and sent to the supply station S. The above-described circulation is automatically repeated to operate the winder device W. The front recovery path C1 and the rear recovery path C1 are combined to form an empty tray recovery path C.

FIG. 1 is a side view of the core tube recovery device A and its front and rear sides. The core tube collecting device A is composed of two guide rails 10 and 11, which are twisted in a single spiral along the feed direction of the empty tray T3 while keeping them parallel to each other. Both ends of the guide rails 10 and 11 are connected to the end of the front recovery passage C1 and the start end of the rear recovery passage C2.

The front-stage recovery path C1 will be described with reference to FIG. 4 as well. It comprises a belt conveyor 20 and a guide 23. Pushers 22 are attached to the belt 21 of the belt conveyor 20 at equal intervals.The guide 23 consists of a lower guide 24 and an upper guide 25.The lower guide 24 is a guide path for the belt 21 and the tray shaft. Guide the department. Further, the upper guide 25 guides the disc 2. On the other hand, the tray is composed of a disc 2 fixed to the base of the peg 1 and a hub 4 formed on the lower surface of the disc 2 via a shaft portion 3. The rear collecting path C2 will be described with reference to FIG. 5 as well. This is composed of a gutter-shaped guide 26 for guiding the hub 4 of the empty tray T1.

Therefore, the empty tray T3 is fed with the hub 4 thereof pushed by the pusher 22, and is fed between the guide rails 10 and 11 with a space left and right. As shown in Fig. 2, the guide rails 10 and 11 sandwich the shaft 3 between the disk 4 of each empty tray T3, T1 and the hub 4 and are pushed by the trailing tray fed from the former recovery path C1. And then sent in sequence. Since the guide rails 10 and 11 make one revolution in a spiral shape, each tray T3 and T1 makes one revolution in the clockwise direction (arrow c) while crossing the guide rails 10 and 11, and once the peg 1 is made vertical. Will be turned downwards. FIG. 3 shows this state, and at this time, the core tube a falls vertically downward from the peg 1 due to the action of gravity. After that, the empty tray T1 without the core tube a is sent to the rear recovery path C2 side by the guide rails 10 and 11, and the guide station 26 of the rear recovery path C2 guides the supply station as shown in FIG. It is shot to S.

As described above, in this embodiment, since the core tube a can be automatically recovered without requiring any labor, no labor is required, and the core tube a is recovered even if the feed speed of the empty tray T3 is increased. Since it is reliable, the operation rate of the winder device can be increased, and the equipment cost is only two guide rails 10 and 11, which is extremely inexpensive.

[0011]

[Effect of device]

 According to the present invention, it is possible to provide a core tube recovery device that can sufficiently follow the improvement in the operating rate of a winder and that can be realized at an extremely low equipment cost.

[Correction content]

Therefore, the empty tray T3 is fed with the hub 4 thereof pushed by the pushing tool 22, and is fed between the guide rails 10 and 11 with a front and rear space. As shown in FIG. 2, the guide rails 10 and 11 sandwich the shaft portion 3 between the disk 2 and the hub 4 of each empty tray T3, T1, and are pushed by the succeeding tray fed from the front collecting path C1. They are sent in sequence in a row. Since the guide rails 10 and 11 make one spiral turn, the trays T3 and T1 make one full turn in the clockwise direction (arrow c) while crossing the guide rails 10 and 11, and once the peg 1 is vertically moved. To turn downwards. FIG. 3 shows this state, and at this time, the core tube a falls vertically downward from the peg 1 due to the action of gravity. After that, the empty tray T1 without the core tube a is sent by the guide rails 10 and 11 to the rear recovery path C2 side, and as shown in FIG. To be Note that the spiral direction of the guide rails 10 and 11 may be reversed, and each tray may be rotated counterclockwise to drop the core tube by gravity.
