Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for automatically packaging disc-shaped spools, such as those wound onto a cylindrical bobbin in an open-end spinning frame.

With the spread of open-end spinning machines, disc-shaped spools unique to open-end spinning machines are being shipped, but when packing the spools into packaging boxes, there are five problems that differ from the traditional spool packing work. There is a point.

That is, an open-end spinning machine (BD-20 manufactured by Toyota Industries Corporation)
The spool spun and wound by a conventional winder (type 0) has a disk-like shape with a smaller axial dimension and a larger diametrical dimension than the spool wound by a conventional winder. Handling is required. When packing the spools for shipment, after checking the front and back sides of the spools, they are usually arranged in four layers, with partition paper inserted between each layer, and stacked in 4 to 5 layers, for example, and 16 to 20 pieces are packed in one box. It is packaged and shipped. However, in this 15-box packaging process, especially when putting the spools into the box for the first time, the work must be carried out in a stooped position with the head inside the box, which is not only strenuous but also very difficult to work with. Improvements were strongly requested. The present invention relates to a method and apparatus for automatically packing the spools of the above-mentioned open-end spinning machine. An object of the present invention is to provide an automatic boxing method and device, characterized in that a predetermined number of spools are skewered and boxed without packaging. The present invention will be explained below with reference to the drawings showing embodiments. As shown in Figs. A spool skewering mechanism A that can be held hanging and movable; a spool supply mechanism B that feeds out the spools 4 arranged on one side of the skewering position 3 in parallel; a conveyor D for feeding the packaging box 7 toward the unloading position 6 of the spool, and a pusher disposed on one side of the unloading position 6 for discharging the packed box T'. It consists of mechanism E.

Next, to explain the operation of each of the above-mentioned mechanisms in more detail, the spool 4 doffed in an open-end spinning machine (not shown) is transferred to the device by the spool supply conveyor 8, and the spool is fed into the spool supply conveyor 8. It is sent to mechanism B.

In this embodiment, the spool supply mechanism B has two rows of belt conveyors 10, 10 that are synchronously driven, and is provided with a swing lever 11 for distributing the spools 4 alternately between the conveyors 10, 10. The spools 4 are distributed on two rows of conveyors 10, 10 by being swung alternately left and right according to a command from a phototube detector 12 disposed at the entrance, and the spools 4 are arranged in parallel on the conveyors 10, 10, respectively. let When at least four spools 4 are arranged in parallel, a stopper 1 provided at the end of the conveyor 10, 10 moves up and down.
3 moves downward, and the rotation of the conveyors 10, 10 feeds the four spools 4, 4 toward the skewering position 3. At the skewering position 3, there is a hawk plate 14 that swings up and down using the conveyors 10, 10 as a fulcrum, a cam 15 that moves the hawk plate 14 up and down, and its drive mechanism 16.
The four spools 4, 4 sent from the two rows of conveyors 10, 10 are transferred onto the hawk plate 14 in an inclined state, and the spools 4 are placed in the slit portion of the hawk play opening 4. Even when the bobbin end 18 is fitted into the spool 17, it slides on the plate 14 and reaches the skewering position, and at the same time the stopper 13 is moved upward to prevent the spool 4 from being fed from the conveyors 10, 10. Subsequently, the drive mechanism 16 described above is operated, and the hawk plate 14 is moved upward to a horizontal position by the action of the cam 15, and the partition paper 5 supply mechanism C is operated, and one sheet of partition paper 5 is transferred to the hawk plate. 4 spools 4,4 on plate 14
placed on top. Next, the operation of the skewering mechanism A, which has been waiting above the skewering position 3, is started. The skewering mechanism A includes a plurality of poles 2 each having a hanger hook member 1 that can be expanded and retracted at the lower end, a drive unit 19 that moves the poles 2 up and down, and the skewering mechanism A along an installed rail 20. and a power unit 21 that moves the hawk plate between the skewering position 3 and the unloading position 6, and when the hawk plate is stopped above the skewering position 3, the hawk plate is located at an extended position of the axis of the poles 2, 2. The bobbin axes of the spools 4, 4 on the spool 14 are positioned. In this way, the skewering mechanism A is actuated with its drive part 19 by a predetermined control device (not shown), for example, the rack 22 provided on the poles 2, 2,
When the four poles 2, 2 are lowered simultaneously by the rotation of the pinions 23, 23 by means of the pinions 23, 23 provided in the drive unit 19, the lower portion of each pole 2, 2 is lowered at its lower end. Conical part. The partition paper 5 is torn from 24, 24, and the hollow part of the bobbin 18 of the spools 4, 4 is inserted. When the protruding ends of the hanger hook members 1, 1 in the expanded state descend to the position where they reach the upper edge of the bobbin 18 as shown in FIG. As a result, the solenoid 28 is energized, its arm 29 moves downward, and the lever 30 is activated.
, 30, the opening/closing rods 31, 31, which are provided through the insides of the poles 2, 2, are pulled up, and the hanger hook members 1, 1 are held in the retracted and closed state as shown in FIG. pass through the inside. When the pawls 2, 2 move down a predetermined distance, the next limit switch 32 is actuated by the projection 26, and the downward movement of the pawls 2, 2 is stopped.
At the same time, the solenoid 28 is released and the rod 31
is moved downward by the elasticity of the spring 33, the hanger hook member 1 is expanded, and the skewering of the spool 4 on the hawk play opening 4 is completed. (See Figure 7) When the skewering of the four spools 4, 4 on the hawk plate 14 is completed in this way, the poles 2, 2 are attached to the skewered spools 4.
, 4 is moved upward, and the uppermost limit switch 3
4, it is stopped and waits.

Next, the hawk plate 14 is tilted, and four new spools 4, 4 are supplied from the spool supply mechanism B onto the hawk plate 14 in the manner described above, and the hawk plate 14 is restored, the partition paper 5 is supplied, and the pole The spools 4, 4 are skewered onto the poles 2, 2 in sequence by repeating the above-described procedure such as lowering the spools 2, 2. As shown in the figure, for example, a 5-layer spool 4 is attached to the poles 2, 2.
4 is skewered, one cycle of skewering operation is completed, and the skewering mechanism A with the skewering poles 2, 2 is laterally moved toward the unloading position 6. A packaging box 7 has already been sent to the unloading position 6 with the top lid opened during the above-described skewering operation, and the skewering mechanism A stops at a position directly above the packaging box 7.

After that, the poles 2, 2 are moved down and the poles 2, 2 are moved downward.
The lower conical end 23 of the hanger hook member 1 is lowered until just before it contacts the bottom of the packaging box 7, and the lower movement is stopped by the action of the limit switch 35. At the same time, the solenoid 28 is activated and the opening/closing rod 31 of the hanger hook members 1, 1 is lowered. , 31 are pulled up, the hanger hook members 1, 1 are retracted, and each spool 4, skewered on each pole 2, 2 is removed.
4 descend all at once due to their own weight, and then each pole 2,
2 is moved upward, each pole 2, 2 moves each spool 4,
4, each spool 4, 4 remains in the packaging box 7. When the transfer and packing of the spools 4, 4 from the poles 2, 2 to the packaging box 7 is completed, the skewering mechanism A moves laterally again toward the skewering position 3, stops above the skewering position 3, and performs the above-mentioned skewering. Perform the action. On the other hand, the packaging box 7 that has been packed with the spool at the unloading position 6 is moved to the hydraulic cylinder 3, for example.
The discharge conveyor 3 is
7, where the top cover is glued. Then, a new packaging box 7 is sent to the unloading position 6 and stands by. Figures 5 and 6 show the above-mentioned skewer pole 2.
This is an example of the hanger hook member 1 provided at the tip of the pole, and its structure and operation will be briefly described.
A block 38 is fixed to the lower end of the block 38, and a hanger hook member 1 constituted by four links is attached to the middle of the block 38. That is, the upper 2 of the quadruple links
A shaft 4 is fixed to the pole 2 side by passing the lower two links 40, 40 through a long hole 41 provided in the block 38.
By moving the block 38 up and down together with the rod 31, the left and right pivot parts 43 of the link protrude and retract from the left and right slits 44, 44 formed in the pole 2, resulting in the state shown in FIG. It is designed so that it can be expanded to the position shown in Fig. 6 or closed to the state shown in Fig. When the quadruple link is expanded, the spool 4 is supported by its protrusion. The hanger hook member 1 in the embodiment is composed of the opening/closing rod 31 that can be slid in the vertical direction and the four-link link as described above, but the hook portion can be directly connected electrically using a solenoid or an electromagnet. It may be configured to open and close.

In this way, the present invention skewers a plurality of poles 2 each having a hanger hook member 1 that can be expanded and retracted at the lower end.
A predetermined number of spools 2 are thrust into the cavity of the hollow bobbin 18 from the lower end thereof through the partition paper 5 to arrive in a skewered manner, and then the pole 2 is moved to the unloading position. After being lowered into the packaging box 7, the hanger hook member 1 is closed and a predetermined number of spools 4,
4 are unloaded and packaged in the packaging box 7 all at once, so disc-shaped spools such as spools unloaded from an open-end spinning machine can be automatically packaged in an extremely efficient manner.

Moreover, when the spool is skewered by the pole, the partition paper is forcibly torn and perforated by the tip of the pole, so that the pieces 45, 45 around the perforation, as shown in FIG. folded inside. This restricts the movement of each spool within the packaging box, prevents the yarn surfaces of adjacent spools from coming into contact with each other during transportation, and avoids the occurrence of so-called misaligned balls, which has beneficial effects on packaging. This also helps reduce packaging labor. Note that the means for vertically moving the poles 2, 2 of the skewering mechanism A is not necessarily limited to the illustrated embodiment, and the present invention can also be achieved by using a hydraulic mechanism, for example.
