Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a palletizing hanger device for vertically storing plate-like parts with openings, such as side panels of automobiles, on pallets. It is.

(Prior Art) This type of hanger device, for example, a device for storing side panels of automobiles in a pallet, has a fork portion extending in the horizontal direction, and two rows of indexing chains are stretched thereon. The fork portion is inserted into the door opening of the side panel, and the side panel is hung from the indexing chain. In this way, each time a side panel is hung, the chain is moved by a fixed pitch, thereby hanging a plurality of side panels on the indexing chain at approximately equal intervals. A plurality of side panels thus hung are carried into a pallet and stored therein. (For example, see Japanese Utility Model Application Publication No. 58-154224.) (Problems to be Solved by the Invention) However, in such a hanger device, a normal roller chain is used as the indexing chain. The pin links and roller links in this roller chain are made of cocoon-shaped steel plates, and therefore, the outer circumferential surfaces of the links, which are the hanging surfaces of the side panels, are curved and extremely slippery. Therefore, even if the side panels are hung at equal intervals by moving the chain at a constant pitch as described above, there is a risk that the side panels will move on the chain after being hung. On the other hand, there is also a risk that the side panels may not be hung on the chain at equal intervals due to control errors in the hanging operation.
If the side panels are not hung on the chain at equal intervals or are easily moved on the chain, problems such as the side panels colliding with each other may occur.

This idea was created with these points in mind.
The object is to provide a palletizing hanger device that can hang plate-like parts on an indexing chain at equal intervals and can maintain that state.

(Means for Solving the Problems) In order to achieve this object, the palletizing hanger device according to the present invention has an opening in a plate-like part, in order to vertically store the plate-like part with an opening in a pallet. It has a fork portion extending in a substantially horizontal direction that is inserted into the opening, and an indexing chain is stretched over the fork portion in the direction of insertion into the opening, and the indexing chain is sequentially moved at a constant pitch to remove the chain. In the palletizing hanger device on which the plate-shaped parts are suspended at predetermined intervals, the indexing chain has a cocoon-shaped roller link that rotatably supports a roller at both ends, and the roller link is attached to the chain. are connected by pin links having end faces that are inclined in a vertical plane parallel to the direction of movement of the Mountains and valleys are formed alternately at regular intervals, and in the valleys, the inclined end surface of the pin link is arranged so as not to overlap the constriction of the cocoon-shaped roller link, and the plate-shaped component is suspended in the constriction. It is characterized by being able to be hung.

(Function) In such a hanger device, the plate-like parts are controlled to be hung in the valley 74 on the index chain 7g, and after one part is hung, the index chain 7g is suspended. After being moved by an amount corresponding to the pitch between the valleys, the next transported part is hung in the next valley 74. In such hanging work, even if the hanging position is slightly shifted, the chain link end faces 72a, 72b
are inclined, so the parts are placed on these end surfaces 72a, 7.
2b to the valley 74.
Furthermore, since the parts are suspended in the valleys 74 of the chain, even if the parts are shaken due to movement of the chain 7g, they will not move from the valleys 74.

(Effect of the invention) As described above, according to the invention, the plate-like parts with openings are always hung at the valley part of the indexing chain, so they are always hung at equal intervals. , the plate-shaped parts can be loaded onto the pallet at suitable even intervals without colliding with each other.

(Example) An example of the present invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing the process of loading side panels of an automobile body into a pallet using the hanger device according to the present invention. As shown in the figure, the side panel 3, which has been conveyed horizontally by the belt conveyor 1, is lifted up by the carrier 5 having a suction mechanism while being horizontally placed, and is moved to the position shown by the dashed line on the track 6. conveyed above. In this position, the side panel 3 is oriented vertically and the hanger device 7 is placed in its door opening 3a.
The tip 7b of the fork portion 7a is inserted through the fork portion 7a.

This hanger device 7 has a generally L-shape as a whole, and has a fork portion 7a extending in a generally horizontal direction.
The base end 7c is supported by a support portion 7d extending in the vertical direction. A travel motor 7e for horizontally moving the hanger device itself on a track 8 is disposed at the upper end of the support portion 7d, and an indexing motor 7f is also disposed. This motor 7
The driving force f is transmitted by chain transmission to an indexing chain 7g stretched horizontally in the fork 7a.

Figure 1 A and B show this index chain 7g
This shows the structure of As shown in the figure, in the pin link 72 connecting adjacent pins 71,
End surface 72 that the door opening end of the side panel 3 comes into contact with
a and 72b are inclined upward and downward alternately with respect to the chain movement direction. These inclined end surfaces 72a and 72b form peaks 73 and valleys 74 at regular intervals. On the other hand, a roller link 77 fixed by two bushings 76 in which a rotating roller 75 is fitted has a cocoon shape like a conventional roller chain. Here, the indexing motor 7f causes the indexing chain 7 to
g is moved by an amount equal to the spacing of the valleys 74,
The side panel 3 is adapted to be hung from the valley portion 74. In this way, the work of hanging the side panels 3 on the indexing chain 7g by the carrier 5 and the movement of the indexing chain 7g are performed alternately, and a plurality of side panels 3 are placed on the indexing chain 7g. is hung. As described above, in this example, the link end faces 72a and 72b of the index chain 7g form peaks and troughs, so the side panel 3 that is hung is guided by the slanted link end faces and is always guided by the slanted link end faces. Tanibe 74
leading to. Since the troughs 74 are formed at equal intervals, the plurality of side panels 3 on the indexing chain 7g are suspended at equal intervals.

The hanger device 7 on which a plurality of side panels 3 are hung in this way is moved to a pallet 9 by its traveling motor as shown in FIG.
It is loaded into this pallet 9. This pallet 9 is placed on a lifting table 9a, and when the side panel 3 is loaded into the pallet 9, this pallet 9 is lifted by the lifting table 9a. Thereby, the engagement between the index chain 7g of the hanger device 7 and the side panel 3 is released. After this, the hanger device 7 is further moved to the position shown by the dashed line in the figure. Pallet 9 is then lowered. Following this, the hanger device 7 is returned to its initial position, which is shown in solid lines in the figure. The side panels 3 are loaded onto the pallet 9 in the manner described above.

In the present invention, the chain link end surfaces 72a and 72b may be linearly inclined, or may be curved as shown in FIG. 3.
