Is configured to be dropped into the container at the collecting position, and further, the packed bag-filled product in the container transferred to the supply part is stacked on the outside of the supply part in a prepared shipping box. It is provided with a stuffing means for refilling.

In a third aspect of the present invention, a bagged product, which is dropped at a constant speed and at a constant interval from a conveyor, is received and dropped in a flat stacking mode into an empty container that has been conveyed to a receiving position at a collecting position in a collecting and distributing unit. Count the number of bagged products with a counting sensor, and if the number stored in advance is reached,
A container filled with a set quantity of the bag-filled product is sent to an adjacent supply standby section through an empty container by an extrusion device, and the empty container is supplied to a dropping position of the bag-filled product. Is.

A fourth aspect of the present invention is a supply preparation position in which a container, in which a set quantity of bag-filled products is filled in a flat stacking form, is carried in from the receiving and collecting position of the accumulation position in the accumulation and distribution unit, and the container is moved to the supply preparation position. One step of the refilling means is stored in the shipping box from the adjacent supply section and stored in a standby manner until the form is stored in advance, and after the container installation arrangement form is formed in parallel, the side face of each container Further, it is possible to supply the container filled with all the bagged products stored all at once by the pushing device to the supply unit while maintaining the parallel state without breaking the arrangement form.

According to a fifth aspect of the invention, a plurality of containers filled with a set amount of bagged products are loaded in a parallel form from a supply preparation position adjacent to each other in the supply unit of the accumulation and distribution unit,
The packed products filled in each container installed in the above-mentioned arrangement form in the shipping box that has arrived to the side are prepared in order from the upper order by the adsorption operation section of the filling means and the container arrangement arrangement form and the flatness. The refilling work is carried out while maintaining the stacked form, and the refilling work is continued until all the bagged products in the parallel containers are exhausted.

[0015]

According to the present invention, the bagging and filling section of the contents conveys the bagged product on the conveyor at a constant speed and at a constant interval to the accumulating and distributing section.

A container is intermittently circulated on a flat surface in the accumulating / distributing section. The container waits for the bagged products to drop at the accumulating position, and stops until a set number is reached, thereby accumulating. The number of accumulated drops is read by the counting sensor, and when the number reaches a constant, it is transferred to the adjacent supply preparation position by the transfer means.

At the supply preparation position, in the supply unit next to the next,
The number of containers filled with the bagged product is stored in a standby state until the number of adsorption operation parts of the packing means operating in one process incorporated in the program is reached, and when a predetermined amount is reached, it is pushed out to the supply part at once.

From the container carried into the supply section, the packing means having the suction operation section at its tip mainly sucks the packed products on the uppermost surface of each container one by one, and "packs" or "rows" in the prepared shipping box. After filling and accumulating in the “tier” position and transferring the total amount in the container to the box, the supply arm is in the idling state, and at this point a command to end the refill operation is issued and the one-step box filling operation Ends.

The empty container is sent to the next container standby unit.

At least two containers are formed in the container standby part so that they can stand by, and the first-arriving container enters the container delivery part, and the container delivery part makes a container stacking preparation position at a stacking position adjacent to the container standby part. Sent to. At this time, the rear storage container in the container standby unit is conveyed to the container delivery unit by the conveyor after the first container moves to the stacking preparation position.

For the container that has reached the container accumulation preparation position at the accumulation position, the bagged product is accumulated in the preceding container by dropping from the conveyor, and this is counted by the counting sensor and set in the program. When the number reaches the number, the preceding container, which has been pushed out to the receiving and accumulating position and has completed filling the set number of bag-filled products by the pushing action, is sent to the supply standby unit in conjunction with the movement of the empty container. The process of filling the above-mentioned bagged product is started.

The container sent to the container stacking preparation position in the above-mentioned stacking place has the bagging products dropped and stacked in the container at the preceding receiving stacking position, and is set by the program. If the counting sensor reads the number reaching the stacking number, the extrusion device headed at the side end position of the stacking point will operate toward the adjacent supply preparation position to push out the empty container and At the same time as the container that has been filled with the set amount is also sent out to the supply preparation position, the empty container reaches the receiving and accumulating position,
Used for dropping and accumulating bagged products.

When a set amount of bag-filled products is filled in the container at the receiving position of the stacking position in a flat stack, the counting sensor reads, and the push-out device advances by the action based on the command and the predetermined amount of bag-filling is performed. The product-filled container is sent to the supply preparation position.

At this supply preparation position, unlike the other parts described above, the container arrangement is arranged according to the packing form in the shipping box.

At least two or a plurality of two or more extruders having the side end position of the supply preparation position as the head are installed in parallel, and the number of installations is the suction of the packing means operating in the adjacent supply section. There are as many as the number of operating parts.

The extrusion device does not operate until the set number of containers 2 are accumulated in a tandem form based on the setting storage command incorporated in the program.

The tandem form is programmed based on the form of packing in a shipping box. That is, in the shipping box, the stacking form filled in the container is one stacked block that is a “row” or a “tier” in plan view, and one of the forms packed in the shipping box at the supply preparation position. It forms a preparatory form for forming one "row" or "column".

Once these desired forms have been prepared, they are transferred all at once to the supply section by the same number of extruders as the plurality of containers.

In this way, at the same time as the arrival of the plurality of containers carried in parallel to the supply unit, a shipping box is prepared beside the supply unit, and when both of them arrive at a fixed position, the suction operation unit of the packing device is immediately activated. A plurality of bag-filled products which are two-dimensionally adsorbed, and the refilling and laminating work is carried out by moving and moving from the bottom of the shipping box in a flat stack without losing the shape at the start of adsorption.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. The main part of the present invention is an integrated distribution unit 1, and this integrated distribution unit 1 is divided into four cross sections in a plan view. The container 2 is largely divided into a stacking position 3, a supply preparation position 4, a supply unit 5, and a container standby unit 6 according to a one-way circulation route.

Each of the accumulating portion 3, the supply preparation position 4, the supplying portion 5 and the container waiting portion 6 in the accumulating and distributing unit 1 has an area where at least two of the containers 2 can be cascaded.

Further, the container 2 is a cubic container having an area equal to or larger than the maximum area of the packaged product 7 and having a desired stacking height and having an open upper surface.

Adjacent to the normal position of the supply unit 5, the container standby unit 6
Is provided, and at least two containers 2 which have been emptied by being refilled in the shipping box 8 by the means to be described later in the supply section 5 are directed toward the container standby section 6 at the side end position of the supply section 5. The extruder 10A is used to perform extrusion at once.

In the container standby unit 6, a space for one container 2 in the front is used as a container delivery unit 6a, and a storage for holding at least one container 2 or a plurality of containers is held in the rear. An accumulating conveyor 6c is installed from the point 6b to the preceding container sending-out section 6a, and is configured to operate only when a command described later is received. Further, the side end of the container sending-out section 6a is arranged. The push-out device 10B having the position at the head is oriented to the adjacent stacking point 3 and is on standby, and when receiving a command, it operates so as to transfer the container 2 of the container sending section 6a to the stacking point 3.

The stacking point 3 is composed of two working parts, like the container waiting part 6 described above. That is, the front is composed of the receiving and stacking position 3a and the container stacking preparation position 3b, and the container 2 from the container standby section 6 is first sent to the container stacking preparation position 3b.

The receiving and collecting position 3 at the collecting point 3
b is a position where a set number of the bagged products 7 are accumulated in the empty container 2.

Creating the packaged product 7 The packaged product 7 completed by the sealing work, which is the final step of the content filling section,
Bagging is carried by a conveyor 9 that is transported at a constant speed and at regular intervals and is provided by a dropping device 9a provided adjacent to the end position of the conveyor 9, that is, a door that horizontally opens and closes in the left-right direction. The product 7 is dropped by the opening / closing operation of the dropping device 9a, and the dropping position is the receiving and collecting position 3a in the above-mentioned collecting place 3, and the bagged product 7 is flatly stacked in the container 2 that has reached the position. It is configured to be put in a form.

Container 2 transferred with the dropping device 9a
The counting sensor 11 provided between the upper end position and the upper end position can read the number of passing bagging products 7 that fall.

The containers 2 sent to the container stacking preparation position 3b in the above-mentioned stacking place 3 are mixed up, although they are different in operational relation.
At the preceding receiving and collecting position 3a, the bagged products 7 are dropped and accumulated in the container 2 as described above, and the counting sensor 11 reaches the number which reaches the set accumulation number incorporated by the program described later. Read, the pushing device 10C headed at the side end position of the stacking point 3 operates toward the adjacent supply preparation position 4, and if the empty container 2 is pushed out, the set amount of the bagged product 7 is filled. The empty container 2 reaches the receiving and accumulating position 3a at the same time when the container 2 which has been completed is also conveyed to the supply preparation position 4 and can be used for the drop accumulating operation of the bagged products 7. Is.

In this way, when the container 2 is filled with the set amount of the bag-filled products 7 at the receiving and collecting position 3a of the collecting place 3 in a flat stack, the counting sensor 11 reads the value and the pushing device operates based on the command. The container 2 loaded with a predetermined amount of the bag-filled product 7 by progressing 10C is sent to the supply preparation position 4.

At the supply preparation position 4, unlike the other parts described above, the container arrangement is arranged according to the form of packing in the shipping box 8.

The extrusion device 10D having the side end position of the supply preparation position 4 as a head has at least two or a plurality of two or more installed in parallel, and the number of installations operates in the adjacent supply units 5 described later. Adsorption operation part 1 of packing means 12
The number is provided according to the number of 2a.

This extruding device 10D does not operate until the set number of containers 2 are accumulated in a tandem form based on the setting storage command incorporated in the program.

This tandem form is programmed based on the form of packing in the shipping box 8. That is, in the shipping box 8, the stacking form filled in the container 2 is one stacked block that is a “row” or a “step” in a plan view, and is packed in the shipping box 8 at the supply preparation position 4. This is to form a preparatory form for forming one "row" or "step" of the formed form.

Once these desired forms have been prepared, they are transferred all at once to the supply section 5 by the same number of extrusion devices 10D as the plurality of containers 2.

A shipping box 8 is also prepared beside the supply section 5 at the same time when the plurality of containers 2 carried in the supply section 5 in parallel form arrive, and when both of them arrive at a fixed position, the packing device is immediately provided. The suction operation part 12a of 12 sucks a plurality of planar packed products 7 and moves and moves from the bottom part of the shipping box 8 in a flat stacking state without deteriorating the shape at the start of the suction, and performs the refilling and laminating work. ..

This refilling operation is continued until there is no bagged product 7 in the container 2, and the suction operation is performed on the empty container 2, but when the suction resistance disappears, it is detected. , Refill work is completed.

It should be noted that all the above-mentioned extruders 10A,
Each of 10B, 10C, and 10D uses, as an example, a cylinder-piston type using a pressure fluid as a motion source. However, the type is arbitrary as long as the above-described action can be expected.

The automated program structure of the present invention will be described next.
It is premised that the stuffing form is a flat stack, and the stuffing form is also often composed of “rows” and “tiers”, and the most common example is 2 rows and 2 tiers in plan view, that is, the plane is 4 tiers. In some cases, there are two stages of one row and three stages, that is, a plane having six stages, and rarely two planes having only “rows” without “steps”.

Next, the total number of items packed in one shipping box 8. The total number of one stacked block can be calculated by dividing this total number by the number of one side formed by the above “rows” and “columns”. There are cases where the total number is odd and even, and the latter Even if it is an even number, there are cases in which the number of stacks is not uniform. For example, when the total number is 22 and the number of stacked blocks is 4, that is, one row and two blocks are formed in two stages, that is, one surface is four blocks.

Therefore, as a method of assembling the program, first, the total number of packings in one box is stored, and then the number of stacked blocks, the number of stacked blocks, and finally the arrangement form of the stacked blocks are set.

In the case of an odd number among the above-mentioned total number and unevenness in the stacking blocks, when the packing boxes 8 are packed, a plurality of containers 2 to be used are arranged so that the load center of the whole box is balanced as much as possible. Of these, it is necessary to pay attention to the ranking of the number of inputs.

By setting and inputting the number of stacked blocks, that is, the number of containers 2 to be used, the number of stacking containers, the arrangement of the containers 2 and the like for one shipping box 8, the container 2 can be moved in the stacking and distributing section 1. The object of the present invention can be achieved by making the program operate in accordance with the program that has been set and input.

In the figure, reference numeral 13 indicates a transfer means of the shipping box 8 to be delivered to the packing section 14 from a box manufacturing department (not shown).
