Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate-shaped body transfer device that grips and transfers both supporting parts of a plate-shaped body.

Generally, for transporting the spools wound by yarn processing equipment (e.g., paper yarn machine, drawing/twisting machine, drawing/false twisting machine, etc.) to subsequent processes (particularly to other factories located in remote areas) or to shipping destinations. , A plurality of the above-mentioned thread bodies (usually 4 to 8 threads) are placed in a cardboard box or wooden box.
All items are packaged together.

However, in such packaging, it is necessary to securely fix both ends of the thread body because the surface of the thread body is easily damaged by the impact. For this reason, it is common practice to enclose support plates having holes or the like for attaching the ends of the spool to the upper and lower surfaces of the cardboard box or wooden box. In particular, when a large number of thread bodies are stacked and packed in multiple stages in order to reduce packaging costs and omit processes such as valetizing, the number of support plates increases. Incidentally, in recent years, automatic packing devices are being developed for reasons such as the fact that winding bodies have become relatively large in diameter and heavy, making it difficult to operate them manually, or in order to rationalize the number of personnel required for packing.

Therefore, in the automatic packaging apparatus, it is desirable from the viewpoint of rationalization to also automate the operation of transferring the support plate to the inside of the cardboard box or wooden box and further to the upper part of the spool. In view of such demands, the inventors of the present invention have conducted extensive studies to provide a transfer layer for plate-like objects that allows for easy release of the grip even in a limited space (i.e. inside a cardboard box or wooden box). This has led to the present invention.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is an explanatory view showing a packing platform using a plate-like object transfer device which is an embodiment of the present invention, and FIGS. 2a and 2b are explanatory views explaining an embodiment of the present invention. , respectively, show the states when gripping and when gripping is released. First, a packing apparatus using a plate-like object and a transfer device according to the present invention will be explained with reference to FIG.

A large number of thread bodies 1 wound by the thread processing device are loaded onto a transport cart 2 (in this embodiment, four stages with four threads per stage), and transported to a predetermined position in front of an upright machine 3. Ru. A rail 5 supported by supports 4 and 4' is placed above the upright machine 3.
is installed, and a drive motor 6 is mounted on the drum ring 5.
A coupling device 8 whose running is controlled by a drive control device 7 and a transfer device 9 according to the present invention are provided. or,
A pallet elevating device 10 is installed approximately below the center of the rail 5, and below the other end of the rail 5 there are a number of support plates 11 for supporting the ends of the spools 1 with iron. The loaded support plate supply table 12 is being reloaded. Further, although not described in detail, the support 4 is provided with a slider 13 that operates so that the uppermost support plate 11 on the support plate supply table 12 is always at a predetermined position. Further, in the vicinity of the pallet lifting device 10, there are a conveyor 15 for supplying the box-like objects 14 onto the pallet lifting device 10, and a roller for discharging the box-like objects 14 on the pallet lifting device 10. A conveyor 16 is installed. To briefly explain such a packaging device, first, the box-shaped body 14 is manually placed on the end of the conveyor 15 and transferred onto the pallet lifting device 10.

Further, the upright machine 3 takes out a predetermined number (in this embodiment, two stages each) of thread bodies 1 from the transport cart 2 transported to the front, changes the state to an upright state at the top, and waits (such (The condition is indicated by a dashed line.) Next, the transfer device 9 and the supply device 8 alternately transfer the support plates 11 from the support plate supply stand 12 and the thread body 1 from the upright machine 3 into the box-shaped body 14. At this time, the box-like body 14 is appropriately raised and lowered by the pallet lifting device 101. Thereafter, by the two operations of the supplying Kamakura device 8, the transfer device 9 is operated only once, and the thread bodies 1 are stacked in multiple stages while both ends of the thread bodies 1 are fixed by the support plates 11. Of course, it goes without saying that the transport cart 2 is updated as appropriate (that is, every two operations of the supply device 8). In this way, after the thread bodies 1 are twilled in multiple stages within the box-like body 14 (at this time, the upper two stages of thread bodies 1 are exposed from the box-like body 14 as shown in the figure), The pallet is discharged from the lifting device 10 onto the roller conveyor 16, and the upper box body 17
Cover. Next, the space between the box-like body 14 and the upper box-like body 17 is sealed with a sealing tape 18 and tied together with an east-shaped object 19. Next, the structure and operation of the transfer device 9 according to the present invention will be explained in detail with reference to FIG. A lift cylinder 901 is installed on the movable body 900 running on the rail 5, and a cylindrical body 903 is fixed to a rod 902 of the lift cylinder 901. A support plate gripping air cylinder 904 and four guide plates 905 are fixed to the cylindrical main body 903. The guide plate 905 also has a guide groove 906 at each end.
and an L-shaped guide groove 907, and a moving plate 909 is installed via a slide shaft 908.
Of course, a protruding locking odor 910 is fixed to the end of the slide shaft 908, and the movable plate 909 is attached to the guide plate 90.
It is designed not to deviate from 5. Further, a sliding plate 912 is fixed to the support plate gripping air cylinder 904 via a rod 911. The sliding plate 912 has sliding grooves 9 on four sides (that is, corresponding to the guide plate 905).
13 and is connected to the movable plate 909 via a spring 914. Further, in the sliding groove 913, there is a guide pin 9 provided at one end of an L-shaped lever 916 rotatably installed on the guide plate 905 with a pin 915.
17 are arranged in a slidable manner. Also, the L-shaped lever 91
A rod 919 is rotatably attached to the other end of 6 by a pin 918.
are hinged together, and a rotating plate 921 is hinged to the end of the rod 919 so as to be rotatable through a pin 9201. Here, the rotating plate 921 is provided with pins 922 and 923 that are movably engaged with the guide book 906 and the L-shaped guide groove 907, and a gripping claw 924 is also provided. Here, the operation of the support plate gripping mechanism in the transfer device 9 as described above will be explained. First, before gripping, the rod 902 is in the state shown in FIG. 2b, but the elevating air cylinder 901 is operated to extend the rod 902. By this downward movement, when the movable plate 909 comes into contact with the support plate 11, the gripping air cylinder 904 operates to shorten the rod 911, and raises the sliding plate 912 relative to the guide plate 905. . Therefore, as the guide pin 917 slides inside the tank movement groove 913, the L-shaped lever 916
is rotated in the direction of the arrow shown in FIG. 2a. The rotation of the L-shaped lever 916 is controlled by the rotation plate 92 via the rod 919.
1 is rotated, but here the rotating plate 921 is connected to the pin 92.
2 and 923 are the guide groove 922 and the L-shaped guide groove 9.
Since it is slidably iron-coupled with 23, it rotates in the direction of arrow B in FIG. 2a while moving its position upward. Therefore, the movement space (particularly the lateral movement space) when the gripping claw 924 attached to the rotation plate 921 rotates can be greatly reduced. In this way, the support plate 11
This state of gripping is shown in FIG. 2a. Next, when releasing the gripped support plate 11, the operation is opposite to that described above, but detailed explanation thereof will be omitted. Furthermore, when releasing the support plate 11 gripped inside the box-like object 14, the movement distance of the rod 911 is made extremely small, especially during the reverse operation of the gripping air cylinder 904, and the elastic force of the spring 914 is used to release the support plate 11. Forcibly pushing it downward is advantageous because the space in which the gripping claws 924 move can be made extremely small. In this example, the plate-shaped object transfer device of the present invention was adopted for transferring a support plate in an automatic packaging device, but it goes without saying that it can be adopted for transferring any other plate-shaped objects. .

Furthermore, although the plate-like object is also gripped from four directions, it may be configured to be gripped only from two directions depending on the shape of the plate-like object and the shape of the gripping claws. As explained above, according to the present invention, when gripping and transporting a plate-like object, it is possible to perform gripping or dismantling operations with a simple mechanism even in a particularly small space (for example, an extremely limited space inside a box-like object). It has the effect of becoming.

Furthermore, since both ends of the plate-shaped object are securely gripped, the operation is very stable compared to those that use suction heads etc. to suction the plate-shaped object, and there are no irregularities on the top and bottom surfaces of the plate-shaped object. However, there is no problem at all.
