An inclined pedestal 4 for placing the box 3 in an inclined position at the end thereof, and a horizontal unloading conveyor 5 are disposed following the inclined pedestal 4. A conveyor 6 is disposed in the upper part to suction and support the upper parts of the canned products A, A, .

In the illustrated embodiment, the transfer conveyor 2 is composed of a belt conveyor, and guide plates 7, 7 are provided on both sides of the conveyor 2 in the transfer direction to guide the canned products A, A, . . . A sorting device 8 is provided in the intermediate part in the direction of transport for sorting the canned products A sent in one row into two rows, and in the center in the transport direction from this sorting device 8 to the end, the canned products A, A partition guide 9 is provided for aligning and transferring the A... in two rows. This sorting device 8 is of a known type, and a sorting rod 8A is vertically installed in the center of the path of the canned products A that are sent in one line, and the canned products A are placed on the right and left sides of the partition guide 9. The system allows pilots to enter the vacant side of the road in sequence.

At the end position of the transfer conveyor 2, canned products A,
The stopper 10 that waits for A... is the canned product A, A.
... is provided so as to be able to appear and retract freely on the path of the canned products A, A...
Partition stoppers 11, 11 for partitioning the number of canned products (in the illustrated example, 1 dozen in 2 columns and 6 rows) are disposed so as to be able to appear and retract from both sides on the path of the canned products A, A, . . . .

Also, on both sides near the end of the transfer conveyor 2,
When the one dozen canned products A separated by the stopper 11 are sent out on the conveyor 2, pressurized air is blown onto the canned products A at the rear end so that there is no drop between the front and back of the canned products A. Pressure air blowing nozzle 1
2 are arranged.

A box supply conveyor 13 is disposed on the side of the inclined pedestal 4. This conveyor 13 conveys the box 3 so that its longitudinal direction is parallel to the inclined base 4, and a pusher 14 consisting of a push plate 14A and an air cylinder 14B is disposed outside a stop station 13A at the end of the conveyor 13. And this Pushsia 14
Then, the box 3 on the stop station 13A is sent onto the inclined base 4.

The inclined pedestal 4 has an inclined position in which the end side of the transfer conveyor 2 is lowered, and its angle of inclination is as follows.
A height position at which the upper end of the box side wall 3A on the upstream side in the transport direction of the canned product of the box 3 supplied onto the inclined pedestal 4 does not come into contact with the lower end of the canned product A suspended and conveyed by the conveyor 6. The upper end of the box side wall 3B on the downstream side is placed in a position where it contacts the lower end of the canned product A. This inclined pedestal 4
A vacuum head 15 is provided in the center of the box to prevent the box 3 supplied thereon from moving erratically. Note that this means is not limited to the one using a vacuum, but may be any other suitable means.

The carry-out conveyor 5 is provided at approximately the same level as the downstream end of the inclined pedestal 4, and is constituted by a roller conveyor in the illustrated example. This unloading conveyor 5
is actively driven by a drive means (not shown),
A box 3 containing canned products A, A, . . . is carried out in the direction of the arrow.

At the end of the carry-out conveyor 5, a conveyor 16 is disposed to convey the packaged canned products to another location, such as a packaging process.

The conveyor 6 is configured as shown in FIG. 3 because the canned products A are intended for products that can be attracted by magnetic force, such as canned products made of magnetic material and bottled products covered with lids made of magnetic material. The pulleys 17 and 18 are made of a material that is not easily magnetic, such as stainless steel.
The magnetic conveyor is constituted by a belt 19 wound between the belts 19 and a magnet 20 disposed directly above the lower running side 19A of the belt 19. Therefore, when the canned product A is conveyed on the transfer conveyor 2 and reaches below the area where the magnet 20 is arranged, the canned product A is sucked up via the belt 19 and placed on the inclined pedestal 4 while adhering to the lower surface of the belt 19. , and will be carried to the middle of the carry-out conveyor 5. In the figure, 21 is a motor for driving the transfer conveyor 21, and 22 is a motor for driving the transfer conveyor 6.

Next, the operation of the above embodiment will be explained.

The canned products A placed on the transfer conveyor 2 and transferred in one line are sorted into two lines by the sorting device 8 and sent toward the end of the transfer conveyor 2.

On the other hand, the boxes 3 with opened lids are supplied to the box supply conveyor 13 and transported, and the first box 3 is stopped on the stop station 13A. Next, the pusher 14 is operated, and the side surface of the box 3 is pushed by the push plate 14A, and the case 3 is transferred onto the inclined base 4, and as shown in the third figure, the box side wall 3 on the downstream side in the transport direction of the canned product A is pushed.
B is high, and the box side wall 3A on the upstream side is placed in a low inclined position.

When the canned product A sent on the transfer conveyor 2 enters the area where the magnet 20 of the transport conveyor 6 is arranged, the canned product A is attracted to the magnet 20 via the belt 19, and due to the belt movement of the belt 19. The canned product A is suspended and reaches the box 3 on the inclined base 4. At this time, when a predetermined number of canned products A have passed, the partition stoppers 11, 11 protrude onto the path to stop the progress of subsequent canned products A, and also prevent the predetermined number of final canned products A from passing.
When the product passes the position of the pressure air blowing nozzle 12, pressure air is blown out from the nozzle 12, and the final canned product A is easily separated from the preceding canned product A.
Pressurized air is applied behind them to fill the gap and ensure alignment.

In this way, a predetermined number (1 dozen) of the canned products A are suspended and supported on the transport conveyor 6, and the first canned product A is tilted on the inclined base 4 in the case 3.
When the canned product A reaches the downstream side wall 3B, the lower end of the canned product A comes into contact with the upper end of the box side wall 3B from the inner side as shown in Figure 3, and drags the canned product A as shown in Figure 3. move in the direction. Along with this movement, the box 3 gradually shifts from an inclined position to a horizontal position,
With this transition, the lower ends of the predetermined number of canned products A suspended and supported by the conveyor conveyor 6 all fit into the case 3. During this period, the upper ends of the canned products A gradually come out of the area where the magnet 20 is placed and are released from their holding, and when the case 3 is transferred onto the carry-out conveyor 5, all of the canned products A are removed. It is placed in the box 3 and carried out by the drive of the carry-out conveyor 5.

During this time, the next box 3 is fed onto the inclined base 4 by the pusher 14, and the partition stopper 11,
The next predetermined number of canned products A separated by 11 are suspended and transported by the conveyor 6 in the same manner as described above, and are continuously packed in boxes in the same manner as described above.

〔Effect of the invention〕

As explained above, according to the packaging apparatus for canned products according to the present invention, the canned products can be stored at a position below the conveyance route of the canned products, which are transported with the upper part supported. The opened case is arranged in an inclined position so that the side wall of the box on the downstream side in the transport direction of the canned product can come into contact with the lower part of the canned product to be transported, and the lower part of the canned product to be transported is in contact with the box. When it comes into contact with the side wall, the lower part of the canned product moves together with the box, and during this movement, the box shifts to a horizontal position, and the lower part of the canned product gradually enters the box, By releasing the support for the canned product at a predetermined position, the canned product is stored inside the box, so the cans do not collide with each other when the canned products are packed into the box. Canned products can be packed smoothly, thereby reliably preventing damage to the canned products.

Furthermore, since the process from supplying canned products to packing can be carried out in a series of steps, the structure can be simplified.
