First, the configuration of the entire apparatus will be explained with reference to FIGS. 1 and 2.

Folded boxes (cartons) 1 created by a box making machine are transferred on a delivery conveyor 2 of the box making machine in a sashimi-like stacked state. Guide plate 4a provided on the top of table 4
The table is guided in series and placed on the table, but since the table is rotating, it is moved along the circumferential direction, and the transfer speed is higher at the outer circumferential position, so it is moved vertically as shown in the figure. The stacked cartons are placed on the guide plate 4 again.
b, and are laterally stacked in a sashimi-like manner, and then sent to the counting/dividing section 5.

The counting/partitioning section 5 is provided with conveyor bells 1 to 6, which transport the cartons, but the cartons that are first transported from the box making machine are transported in a lying state. Since the cartons have been placed in an upright position, it is necessary to line them up in an upright manner, so the first carton is transported while being held up a little by a raising skewer 7 provided in an inclined position. In this case, if the conveyor transfer speed is set lower than the speed of the cartons that will be transferred later,
The flow is compressed and the carton stands upright. In this way, the leading carton is moved while being supported by the first support skewer 8 at a position where the front side is supported in an upright state and is slightly transferred by the conveyor bell l-6. Incidentally, after the first support skewer 8 supports the head of the carton group, the raising skewer 7 is no longer needed, so it is moved to the inoperative position by the air cylinder 7a. If this first group of cartons is carried out first when a group of cartons is transferred, then the alignment of the cartons will continue naturally.

(The operation of this skewer for raising the car is described in Fig. 8 of the drawing and its explanation in the previously filed Japanese Patent Application No. 63-237497.) The front side is supported by the first skewer 8 for support. The group of cartons to be transported is divided into the required number of cartons by a counting sensor 9 and a partition skewer IO provided on the lower surface of the conveyor belt 6 in a counting/partitioning section 5.

In this way, in the counting/dividing section 5, the first group of cartons flowing is received by the first supporting skewer 8, and the counting sensor 9 counts a predetermined number of cartons, and when the predetermined number is reached, the dividing skewer 10 The partitioning device will be explained with reference to FIGS. 3 to 7.

As shown in FIGS. 1 and 2, the count/divider section 5 is
Following the turning device 3, which consists of a disc-shaped table 4, a motor 4c for rotating it, and guide plates 4a and 4b for guiding the cartons 1, there is a sensor for counting the number of cartons 1 that are flowing. 9, ■ A partition skewer 10 for partitioning the groups of cartons according to the signal from the counting sensor 9, an air cylinder 12 for operating the skewer 10, and the partition skewer 0 to 10 are divided in the carton transport direction to separate the cartons. A partitioning device 1 consisting of an air cylinder 13 that acts to divide the group into front and rear sections].

■ A partition skewer moving device consisting of a base 14 to which the partition device 11 is attached, a guide shaft 15 for guiding the base 14, and an air cylinder 16 for moving the partition device to move the base 14 in the carton flow direction. , ■ A belt conveyor 6 for conveying the carton 1;
A transfer device comprising a motor 6a for driving the belt conveyor 6; (1) A presser guide plate 17 for pressing the top surface of the carton group so that the cartons do not fly upward when the partition skewer IO is inserted into the carton group; A carton bunch interleaving prevention device consisting of an air cylinder 17a for control is provided. In addition, the code|symbol 18 is a main body machine frame.

Further, the rear end portion of the carton group supported by the front support skewer 8 divided by the partition skewer 10 is configured to be supported by the partition and the rear support holder 19, and the carton group from which the division is completed is supported by the partition skewer 10. After being transferred to the carton boxing device position following the counting/dividing section 5,
The front support skewer 8 and the rear support skewer 19 are configured to return to their old positions by an air cylinder device as appropriate and repeat the same operation.

Next, the configuration of the partition device 11 will be explained.

The partition skewer 10 is formed by two partition plates 10a and 10b, and as shown in FIG.
The partition plate 10a is fixed to the mounting plate 20, but the partition plate 10a is fixed to the mounting plate 20.
0b is movable in the carton transfer direction via the piston rod of the air cylinder 13 fixed to the mounting plate 20, and is housed within the window frame of the partition plate 10a to form a single partition ratio of 10. It is configured. The mounting plate 20 is attached to a U-shaped frame 21 that is mounted at a variable mounting angle on a base 14 that is slidably supported on a guide shaft 15 fixed to the main machine frame 18 (see FIG. 5). a)
As shown in (b), it is guided by a guide shaft 22.22 provided on the mounting plate 20, and can be moved up and down by an air cylinder 12a attached to one end of a piston rod 23, which is also attached to the mounting plate 20. . One end of this air cylinder is fixed to the cylinder mounting plate 24,
Another air cylinder 12b is also fixed to this air cylinder mounting plate 24, and one end of its piston rod 25 is connected to the U-shaped frame 21. In addition,
Reference numeral 26 is a guide plate for the air cylinder mounting plate 24 fixed to the U-shaped frame 21.

Next, its operation will be explained.

Upon receiving a signal indicating that the required number of carton groups has been counted by the counting sensor 9, the cylinder 12a is actuated to slightly increase the partition ratio 10 formed by integrating the partition plates 10a and 10b. act to differentiate between. In this case, the air cylinder mounting plate 24 is not displaced. Next, the air cylinder 12b is activated to move the entire partitioning device 11 upward to ensure that the carton groups are separated according to the partitioning ratio of 10.
is operated to displace the partition plate 10b in the carton transport direction, thereby widening the interval between the divided cartons. The sequence of operation is shown in FIG. 6 by the arrows ■■■■.

Note that the reason why two air cylinders are used to increase the partition ratio of 10 in this way is that control can be performed easily, and one air cylinder may be used to operate in two stages.

The overall configuration of the apparatus has been described above, and next, the operation of dividing cartons based on the partitioning ratio will be described.

Figure 7 is a flowchart of the operation of the device, in which folded boxes (cartons) 1, which are shaped like sashimi and flowed from the box making machine, are folded into upright (cartons) 1.
The counting sensor 9 counts the number of sheets that have been lined up (it may be in a slightly tilted state), and when the specified number has been reached, the skewer 11 for partitioning is first inserted a little, and then Move the skewer slightly faster than the flow speed of the cartons to form a gap between the cartons, and then insert the partitioning skewer 11 further, and move the skewer to the partition plate 10a,
By opening the carton into two pieces 10b in the front and back, the carton bundles can be reliably separated and sorted.

That is, as shown in FIG. 1, the table 4 of the turning device 3 is rotated, the cartons 1 that have flowed from the box making machine are placed thereon, and the cartons 1 are moved in the circumferential direction to rotate the cartons 90 degrees. Thereafter, the carton is sent onto the conveyor belt 6 along the table guide 4b.

At this time, the carton transport speed by the rotary table 4 is set higher than the transport speed of the conveyor belt 6 to compress the flow of cartons, and the cartons are made to stand up by using a carton raising skewer or the like. Thereafter, the carton is moved by a belt conveyor 6 while the front side is supported by a skewer 8, and the number of cartons 1 is counted by a counting sensor 9 attached below, as shown in FIG.

When the number of cartons reaches the specified number, air cylinder 1
2a is driven to insert the tip of a partition skewer 10 formed by integrating partition plates 10a and 10b into the space between the cartons a little. At this time, as shown in Fig. 7 (■), the air cylinder 17a for preventing carton sorting is activated to
7 to prevent the carton from being pushed by the partition skewer 10 and popping out.

Thereafter, with the partition skewer 10 inserted, the air cylinder 6 for moving the partition device is operated to move the partition skewer 10 in the direction of flow of the cartons at a speed slightly faster than the conveyor speed. (See FIG. 7 (■)) When the partition skewer 10 is moved to create a gap between the cartons, the air cylinder 12b is operated to insert the partition skewer 10 deeper between the cartons. At this time, the guide 17 prevents the car from jumping up. (See Fig. 7 ■) After that, the air cylinder 13 is operated and the partition plate 10a is
, 10b of the partition skewer 10 formed by integrating the partition plate 1
0b is pushed out in the direction of carton movement as shown in FIG. 7, and the cartons are separated and divided. After inserting the rear support skewer 19 into the thus divided space and sandwiching the divided carton between the front support skewer 8 and the rear support skewer 19, as shown in FIG.
As shown in ~ ■, a separately provided downward U-shaped conveyance skewer 2
7 is lowered from above to sandwich the carton bundle from the front and back as a bundle (see FIG. 7 ■), and the cartons are placed on the side of the carton boxing device following the belt conveyor 6 ( (not shown).

In the above embodiment, the partition skewer is inserted into the carton group from below in order to partition the cartons, but the partition skewer is not necessarily limited to the bottom, and may be inserted from above or from the side. Further, although the object is a carton, it is not limited to this, and can also be used to separate cards, envelopes, etc.

〔Effect of the invention〕

In the present invention, the partition skewer 10 for separating the groups of cartons is constructed by integrating two partition plates 10a and 10b, and when separating the cartons, the partition skewer is first inserted a little into the group of cartons, and then it is inserted deeper into the group. By operating the insertion in two stages, and by making one partition plate 10b of the inserted partition skewers movable,
Since the intervals between the divided cartons are further widened, the curd can be reliably divided without damaging the cartons.

In addition, since the carton bundles can be reliably sorted without manual intervention, it is possible to automate the sorting of carton bundles without damaging the cartons or, conversely, without injuring one's hands with the cartons. By installing a packaging device in the post-process, automation of packaging can be easily achieved.
