Description

[Detailed explanation of the idea] The present invention relates to a product loading device.

Products pressed by the three-dimensional transfer press are transported to a product stacking table, and once the products are stacked on this stacking table, they are stacked vertically and then the stacked products are transported to a predetermined location. However, conventionally, this series of operations has been carried out by combining existing devices, but these methods are not suitable because the stacking speed is slow and the stacking accuracy is poor. Additionally, a special drive device is required for conveyance, making it expensive.

The present invention provides a product loading device that eliminates such drawbacks, and its features include a product support that supports the pressed product on the downstream side of the transfer press, and a product loading device that supports the pressed product. A product stacking table for stacking products in a horizontal or vertical position, a product cradle for transporting the stacked product groups from the product stacking table, and a pallet for loading the stacked product groups are sequentially arranged to support the products. A delivery trolley is provided, which is capable of reciprocating between the product stacking platform and the product stacking platform and is interlocked with a feed bar, and is also capable of reciprocating between the product receiving platform and the pallet. A product gripping device is provided on the base truck, which is movable up and down, and supported so as to be rotatable about a horizontal axis, and the upper end of the product in a vertical position on the product stacking table is provided above the downstream side of the product stacking table. A support block capable of locking is provided, and a rotary frame for supporting a group of products stacked in a vertical position is rotatably erected on the downstream side of the product pedestal, and is movable up and down on the delivery trolley. at least one pair of arms supported and capable of supporting products stacked in a horizontal position on a product pedestal in close proximity to each other, or an L-shaped support capable of supporting products stacked in a vertical position on a product pedestal; This is due to the fact that the frame is provided, and according to this configuration, it is possible to "grasp", "transport" and "stack" the products.
It is a device that allows each step of "feeding out" to be performed smoothly in order, and products that are produced and sent out one after another by a transfer press.
Once multiple products are stacked horizontally or vertically on the product stacking table using the product gripping device, the product group on the product stacking table is carried out by the product holder, and the product group is transferred from the product holder onto the arm or L. Since the products are loaded onto a pallet using a shape support frame, the movement stroke of the product gripping device can be reduced, the stacking speed can be increased, and the stacking accuracy can be improved. Therefore, it is ideal as an automatic palletizer for transfer presses. Furthermore, since the cart is moved back and forth in conjunction with the feed bar, no special drive device is required, and it is highly economical.

Next, the first elevating shaft 39 is slightly raised. As a result, the product 4 on the support 12 is lifted up. Next, the foundation truck 32, which is interlocked with the movement of the feed bar 1 via the connecting rod 35, is fed at high speed in the direction of arrow B. Next, when the base truck 32 comes close to the product stacking table 17, the fine adjustment truck 36 is appropriately moved by the servo motor 38 to bring the product gripping tool 44 to a predetermined position above the product stacking table 17. Next, the first elevating shaft 39 is lowered by the fourth cylinder device 41, the product 4 held by the product gripper 44 is placed on the stacking table 17, and the suction by the vacuum cup 46 is released. Next, the same operation as described above is repeated, and a predetermined number of products 4 are stacked on the stacking table 17. Next, after the stacking table 17 is raised by the second cylinder device 21, the second conveyor 14 is operated to move the product receiving table 2 to the position shown in FIG.
2 is moved in the direction of arrow C and placed below the product 4 on the stacking table 17. Next, the stacking table 17 is lowered and the products 4 on the stacking table 17 are placed on the receiving table 22. Next, the pedestal 22 is moved in the direction of arrow B and brought to its original position. Next, the arm 61 of the product delivery device 51, which is waiting at the position shown in FIG.
As shown in the figure, move arm 6 in the direction of arrow D.
Slip the bottom end of 1 under product 4. Next, the piston rod of the third cylinder device 27 is contracted and the rotating frame 25 is rotated in the direction of arrow E and brought down, and then the second elevating shaft 56 is raised by the sixth cylinder device 58, and then the delivery truck 52 with arrow B
Then, the second elevating shaft 56 is lowered, thereby transporting the product 4 held by the arm 61 as shown by the arrow F to the pallet 3.
0. Next, when the traveling vehicle 31 is run, the products 4 stacked on the pallet 30 are
is sent to a designated location.

Next, when stacking the products 4 in a vertical position, remove the lifting main body 59 and the arm 61 from the swivel device 60, as shown in FIG.
0, a vertical stacking delivery device 65 consisting of a lifting main body 62, a large number of L-shaped support frames 63, and product side edge supports 64 is disposed. Next, in FIG. 1, after gripping the product 4 on the product support 12 with the grip 44, the first elevating shaft 39 is slightly raised, and then the grip 44 is oscillated by the swinging device 47, and the Set the state shown in the imaginary line in Figure 1. Next, the foundation truck 32
is fed at high speed in the direction of arrow B, and the lower end of the product 4 is placed on the stacking table 17, and the upper end is placed on the support block 48. By repeating this operation, a predetermined number of products 4 are vertically arranged and stacked on the stacking table as shown by the imaginary lines in FIG. Next, stacking table 17
, move the pedestal 22 at the solid line position in FIG. The upper end is placed on the rotating frame 25.
hand it over to Next, the support block 48 is rotated in the direction of arrow F by the fifth cylinder device 50 and brought to a position where it does not hit the product 4. Next, the pedestal 22 is moved in the direction of arrow B and returned to its original position. Next, the delivery cart 52 at the position shown by the solid line in FIG. Next, the second elevating shaft 56 is raised to transfer each product 4 from the pedestal 22 to the support frame 63. Next, after rotating the rotating frame 25 in the direction of the arrow E, the delivery cart 52 is moved in the direction of the arrow B, and the second lifting cylinder 56 is lowered, as shown in the arrow G in FIG.
Each product 4 may be transported and placed on the pallet 30 as shown in FIG.

As described above, according to the present invention, when loading products, a plurality of products (groups) are stacked on a product stacking table, and then the stacked product groups are taken out and loaded onto a pallet. Compared to loading products directly onto a pallet, the movement stroke of the product gripping device can be significantly shortened, and the tasks of "grasping,""transporting,""stacking," and "feeding" products can be carried out smoothly in order. , it is possible to increase the stacking speed and improve the stacking accuracy. Therefore, it is ideal as an automatic palletizer for transfer presses. Moreover, since the cart is moved back and forth in conjunction with the feed bar, no special drive device is required, and it is highly economical.
