indicates the loading cassette 6 in the loading section a by arrows C and D.
For example, it is constructed in the form of a conveyor so as to be able to move in a direction. In addition, the loading cassette 6
The purpose of making it movable is to load products into the loading cassette 6 in double rows. 7 is a feed bar 2 located below the loading section a of the table main body 4.
This is a receiving lifter that receives products from the table and lowers them into the loading cassette 6 on the table main body 4. This receiving lifter 7 consists of a cylinder device 8 located below the table main body 4 and a product receiving device 9 that can be raised and lowered by the cylinder device 8 between a position below the table main body 4 and a product release position of the feed bar 2. It is configured. Note that this receiving tool 9 is configured so that it can pass through the bottom of the table main body 4 and the loading cassette 6. For example, the receiving device 9 is composed of a plurality of rods, and the bottoms of the table main body 4 and the loading cassette 6 are constructed in a mesh or slit shape through which the rods can pass. Reference numeral 10 denotes a pair of guide rails arranged on both sides above the turntable 1 in the product conveyance direction A. 1
Reference numeral 1 designates a product chucking device that is guided by the guide rail 10 and is movable between the unloading section b of the turntable 1 and a position above the pallet 3. That is, this chucking device 11 is connected to the guide rail 10.
A traveling trolley 12 that can freely run on the top, and this traveling trolley 1
The chucking body 14 is suspended from the chucking body 2 via a cylinder device 13 so as to be freely raised and lowered, and a plurality of claws 15 are provided on both sides of the chucking body 14 and can hold and release the products in the loading cassette 6. has been done. Reference numeral 16 denotes an auxiliary cassette that is provided above the receiving lifter 7, that is, above the table main body 4, and receives products from the feed bar 2 auxiliary (temporarily). This auxiliary cassette 16
consists of a crossbeam 17 provided between the pair of guide rails 10, and a pair of product holding arms 19 suspended from the crossbeam 17 via cylinder devices 18 so as to be able to rise and fall freely. . In addition,
The cross beam 17 is configured to be movable in the product conveyance direction by cylinder devices 20 respectively mounted on a pair of guide rails 10.

Next, the product loading operation will be explained.

As shown in FIG. 2, when the loading cassette 6A, which can be loaded in two rows, is empty, the receiving device 9 of the receiving lifter 7 is first raised, and the loading cassette 6A is transported by the feed bar 2. Receive products in sequence. At this time, each time a product is received, the receiving tool 9 is sequentially lowered by the thickness of the product to guide the product to the first row position c of the loading cassette 6A, and the height of the product in the uppermost position is always constant. It is like that. When the first row in the loading cassette 6A is full, the product holding arm 19 of the auxiliary cassette 16 is first lowered to a height where it can receive the products from the feed bar 2, and the table main body 4 is moved in the direction of arrow C. The second row position d of the loading cassette 6A is aligned with the final product feeding position e of the feed bar 2. When the loading cassette 6A is moved, the products sent from the feed bar 2 are temporarily held by the auxiliary cassette 16. When the movement of the loading cassette 6A is completed, the receiving lifter 7 is operated to move the auxiliary cassette 1.
Receive product 6 and place feed bar 2 on top of it again.
Receive products from Loading cassette 6A-2
When the row is full, the auxiliary cassette 16 is again lowered to a height corresponding to the feed bar 2, and the receiver 9 is lowered below the table body 4, and then the table body 4 is rotated 180 degrees. Then, the loading cassette 6A loaded with products is located at the unloading section b below the chucking device 11, and the empty loading cassette 6B is located at the loading section a below the auxiliary cassette 16. At this time, the table main body 4 is moved in the direction of arrow D so that the first row of empty loading cassettes 6B is placed above the receiving lifter 7. And in the loading section a,
When the turntable 1 rotates, the products temporarily held by the auxiliary cassette 16 are transferred to the receiving device 9, and then the products from the feed bar 2 are sequentially loaded via the receiving device 9 into the loading cassette 6B.
In the unloading section b, after all the products in the loading cassette 6A are held at once by the claws 15 of the chucking device 11, the traveling cart 12 is moved to the pallet 3.
Move to the top and release the product into pallet 3.

In this way, the products conveyed by the feed bar are mechanically loaded into the loading cassette in the same condition as they are loaded onto the pallet, which minimizes the space between the products within the pallet. It is possible to prevent the load from collapsing, and since an auxiliary cassette is provided in the loading section, there is no need to interrupt the feeding operation of the feed bar even when the loading cassette is moved. Therefore, at the unloading section, sufficient time can be taken for transferring products from loading cassettes to pallets. Furthermore, the auxiliary cassette
Since it is composed of a cylinder device arranged vertically and a product holding arm that is connected to the cylinder device and can be raised and lowered, the product can be supported from below, and therefore the product does not deform itself. You can temporarily receive without giving.
