At the same time, a pallet station PS is set to place pallets P for loading goods W in multiple stages, and a plurality of pallets P are stored on the traveling cart 1 to load the pallets. A pallet storage and supply device 5 is provided for supplying pallets one by one to the station PS, and a robot-type transfer device 11 equipped with a holding device 12 for holding items W is also provided.

(Function) The pallet loading device of the present invention moves the traveling cart 1 to a position close to the article station WS into which the article W has been carried and the corresponding pallet station PS, and loads the robot type on the traveling truck 1. The holding device 12 of the transfer device 11 holds the product W at the product station WS, and the transfer device 11 transfers the product onto the pallet P of the pallet station PS. Move to a position close to the pallet station PS, and move the traveling trolley 1
Pallets P are supplied to the pallet station PS from the upper pallet storage and supply device 5.

(Embodiment) An embodiment of the pallet loading device of the present invention will be described with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a running trolley, which can run in both directions on a rail 2 serving as a running path, and at multiple locations along one side of the rail 2, there are goods W. Item stations WS corresponding to the types of items W are set up, and at multiple locations along the other side of this rail 2, pallets corresponding to the same types of items W are installed, facing each of the item stations WS slightly diagonally. tuto station
PS is set.

Each of the article stations WS is provided with an article carry-in conveyor 3 made of a roller conveyor or the like with its conveyance direction perpendicular to the rail 2, and is adapted to carry the article W into the article station WS. .

Each of the pallet stations PS is provided with a pallet transport conveyor 4 consisting of a chain conveyor or the like, with its conveyance direction perpendicular to the rails 2, and the pallet P loaded with items W is transported to the pallet station PS. It is now being removed from the

A pallet storage and supply device 6 is provided on the traveling carriage 1. This pallet storage and supply device 5 includes a pallet conveyor 6, which is composed of a chain conveyor or the like whose conveyance direction is perpendicular to the moving direction of the traveling cart 1, so as to be connected to the pallet conveyor 4 of each pallet station PS. A pallet hoisting table 7 is provided for the pallet conveyor 6, a pallet storage frame 8 is provided on the upper outside of the pallet hoisting table 7, and air cylinders 9 are used to open and close the pallet storage frame 8 on both sides of the pallet storage frame 8. Pallet locking pieces 10 that move forward and backward are provided on both sides of the pallet P. A plurality of pallets P are stored in a stacked state in the pallet storage frame 8 and supported by the pallet lifting table 7 or the pallet locking pieces 10. It's becoming like that.

Further, a vertically articulated robot-type transfer device 11 is provided on the traveling trolley 1 so as to be rotatable in the horizontal direction, and a holding device 12 is attached to the tip of the vertically articulated arm of this transfer device 11. is provided to be horizontally rotatable, and this holding device 12 can be moved around the main body of the transfer device 11 by the rotation of the transfer device 11 and the movement of the vertical multi-joint arm of the transfer device 11. can move freely within the cylindrical area.

The holding device 12 holds the article W, and as shown in FIGS. 3 to 6, the horizontal rotation shaft 13 is always kept vertical at the tip of the vertical multi-joint arm of the transfer device 11. A supporting frame 14 is provided at the lower end of this horizontal rotation shaft 13, and a clamping plate 15 fixed to one side of the article W is provided at the lower part of one side of this supporting frame 14, and this fixed clamping Opposing the plate 15, a clamping plate 17 is provided at the lower part of the other side of the support frame 14 by means of an air cylinder 16, and the clamping plate 17 can move horizontally toward the fixed clamping plate 15 and move back and forth horizontally to grip the other side of the article W. This clamping plate 1 is rotated by an air cylinder 18 on the outer side of 17.
A pair of L-shaped hooks 19 are provided that move forward and backward from the outer side of the item 7 to the inner lower part and connect to the lower surface of the other side of the item W. Since it rotates in the horizontal direction, the directions of the clamping plates 15, 17 and the hook 19 can be set freely.

Next, the operation will be explained.

A large number of stacked empty pallets P are transferred to and stored in the pallet storage and supply device 5 of the traveling truck 1 using a forklift (not shown) or the like.

Then, the traveling cart 1 is sequentially moved to each pallet station PS, and
, the pallet conveyor 6 of the pallet storage and supply device 5 on the traveling trolley 1 is moved to the pallet station.
It is connected to the pallet transport conveyor 4 of the PS, and the pallet elevating table 7 is raised to support a large number of pallets P in the pallet storage frame 8. In this state, the pallet locking piece 10 is closed by the air cylinder 9 and the pallet is lifted from below. 2
The lowest pallet P was transferred onto the pallet conveyor 6 by advancing to both sides of the pallet P and lowering the pallet lifting table 7, and this pallet P was connected from the pallet conveyor 6. Transfer the pallet onto the pallet unloading conveyor 4 of the pallet station PS.

The article W is placed at the tip of the article carrying conveyor 3 corresponding to the type, that is, at the article station WS.
When the goods are carried in, the traveling trolley 1 is moved to a position close to this article station WS, and the holding device 12 is moved to the tip of the article carrying conveyor 3 by the transfer device 11 on the traveling trolley 1, and the movable clamping Board 1
7 toward a fixed clamping plate 15 using an air cylinder 16 to clamp the item W from both sides, and at the same time, the hook body 19 is advanced toward the lower part of one side of the item W using the air cylinder 18, It is inserted into the lower part of one side of the article W through a gap such as the rollers of the article carrying conveyor 3, and the holding device 12 holding the article W in this way is moved to the pallet corresponding to this type of article W on the opposite side of the rail 2. The product is moved to the pallet conveyor 4 of the station PS, and the article W is transferred onto the pallet P of the pallet conveyor 4.

By repeating this process, the goods station
Items W are loaded from the item delivery conveyor 3 of the WS onto the pallet P of the pallet station PS in a predetermined pattern and in a predetermined number of stages.

Then, the pallet P on which the loading of the goods W has been completed
is carried out from the pallet station PS by the pallet transport conveyor 4, and
The pallet transport conveyor 4 of the PS has a traveling trolley 1.
A new empty pallet P is transferred from the pallet storage and supply device 5, and the goods W are loaded.

〔Effect of the invention〕

As described above, according to the present invention, a traveling truck that moves a transfer device having an article holding device to a plurality of article stations and a pallet station has a pallet storage and supply device, and the pallet storage and supply device has a pallet storage and supply device. Since the pallet is supplied to each pallet station, the pallet supply function can be consolidated on the traveling trolley, thereby eliminating the need to arrange a device to supply pallets to each of the plurality of pallet stations. , it is possible to prevent increases in space and equipment costs.
