Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a boxing device for storing and packing a plurality of items in a box.

[Conventional technology]

For example, in a box packing device that sequentially stores and boxes multiple items in a box with an open top, a holding mechanism holds the items brought into the carry-in position, and this holding mechanism is used to hold the boxes waiting in the cartoning position. After horizontally moving above a predetermined storage part to position the item, the holding mechanism is lowered to lower the item into the predetermined storage part, and after releasing the item here, the holding mechanism is raised and moved horizontally. A method that would allow it to return to its original loading position was considered.

[Problem that the invention seeks to solve]

In the case of the box packing equipment described above, in order to increase the box packing capacity, the first priority is to shorten the time required for the movement of the holding mechanism. Make it faster.

To drop an article into a storage section in a box by shortening the lowering of a holding mechanism in a boxing position or by eliminating the lowering at all.

When the holding mechanism returns from the cartoning position to the carry-in position, it simultaneously performs upward and horizontal movements.

Possible methods include:

However, depending on the nature of the product, it may not be possible to increase packaging capacity using this method. When packaging soft and flexible items such as pack products filled in flexible containers such as resin bags, the following method will allow the holding mechanism to move from the carry-in position to the loading position. Even after moving and stopping, the item may continue to shake, causing the item to be unloaded outside of its designated storage area, or the unloaded item may topple over. jumped,
As with method 2, the item may fall out of its designated storage space or fall over. If a member is provided to prevent misalignment, falling, etc., this member will become an obstacle, making it impossible to carry out the method described in (a).

The present invention has been made in view of these points, and an object of the present invention is to efficiently pack items into boxes regardless of the nature of the items.

Then, the case C is lifted to the packing position 11 and positioned between the guide bars 20. Thereby, the partition plate 13 is inserted into the case C to divide the inside of the case C in the longitudinal direction, and the five Storage parts C1, C2,
Form C3, C4, and C5.

In addition, the stopper 24 is located at the boxing position 1 when the case C is placed in the box.
1, the stopper 23 lifts up to stop the subsequent case C, and the stopper 23
is raised and the case C is raised to the boxing position 11, and then the stopper 24 is lowered, and the stopper 24 is further lowered when the lifting plate 22a is lowered and the case C is not below the boxing position 11.

The pack products P are sequentially conveyed by the pack conveyor 2, and when they are stopped at the guide stopper 9 as shown in FIG.
When the next packed product P is stopped at the stopper part 7a of the pusher 7, the pusher 8 is advanced onto the pack conveyor 2 using the air cylinder 6, and this packed product P is transferred to the carry-in position 3. At the same time, the following pack products P are stopped at the stopper part 8a of the pusher 8, and thereby, the two pack products P are lined up on the support base 4, and the stopper of the pusher 8 is moved. At section 8a, the subsequent pack product P is stopped.

Note that each pusher 7, 8 is retracted from above the pack conveyor 2 in a state where there is no pack product P on the support stand 4.

The two pack products P on the support stand 4 are
The movable body 27 of the horizontal movement mechanism 25 is positioned by each locking rod 40, and in this state, the chuck body 36 of each chuck mechanism 35 is positioned as shown in FIGS. 1 and 3. The opening/closing drive source 37 closes and holds the upper part of the packaged product P, and as shown in FIG. The chuck mechanism 35 is stopped above the storage part C1, and each chuck mechanism 35 is lowered by an air cylinder 38, and the lower part of the pack product P is transferred to the storage part through between the guide part 12a of the guide cylinder 12 and the guide flap 15 which has been rotated to the right. Insert it into the top of C1,
The chuck body 36 of each chuck mechanism 35 is opened by the opening/closing drive source 37 to drop the pack product P into the storage section C1, and then the moving body 2 of the horizontal movement mechanism 25
7 is held to the right, and at the same time each chuck mechanism 35 is raised by the air cylinder 38, and each chuck mechanism 35 returns above the support base 4 at the carry-in position 3 while drawing a parabola.

Then, each storage section C1, C2, C of case C

Here, each storage section C1, C2, C3, C4, C
5, when storing the pack products P in order from the first storage part C1 to the fifth storage part C5, the partition plate 13 is pushed in order due to the deformation of the pack product P that fell. Since the deformation of the plurality of pack products P is accumulated on the last partition plate 13, the width of the last storage section C5 becomes considerably narrow, and no pack product P can fit into the last storage section C5. However, as mentioned above, after storing the pack product P in the odd-numbered storage compartments C1, C3, and C5 from the end, store the pack product P in the remaining even-numbered storage compartments C2 and C4. Because it is stored, pack products P that have fallen
deformation is not accumulated in the partition plate 13, and the pack products P can be reliably stored in all the storage sections C1, C2, C3, C4, and C5.

Then, by repeating such an operation, the packaged products P carried onto the support stand 4 at the loading position 3 are placed in each storage section C1, C2, C of the case C at the loading position 11.
3, C4, and C5, and after storing 10 pack products P in case C, lower the elevating plate 22a of the elevating mechanism 2 to lower the case C onto the case conveyor 21, and lower the lowered state stopper 23. It is carried out from below the boxing position 11 by passing the top through it.

2, C3, C4, C5, but the chuck mechanism 35 is fixed to the moving body 27 of the horizontal moving mechanism 25, and the pack product P is dropped into each storage section C1, C2, C3,
It may also be dropped from above onto C4 and C5.

〔Effect of the invention〕

As described above, according to the present invention, an item can be guided to a predetermined storage part in a box by a rotatable guide body, and this item can be positioned in a predetermined storage part in a box by a partition body. This prevents the items stored in the box from shifting or falling over, making it possible to increase the movement speed of the item holding mechanism, and omitting part or all of the lowering of the holding mechanism at the boxing position. In addition, when the holding mechanism returns from the boxing position to the carry-in position, the holding mechanism can simultaneously move upward and horizontally, making it possible to carry out the boxing work extremely efficiently. Since the interlocking mechanism can interlock every other guide body, even if there are many guide bodies, all the guide bodies can be rotated with one or two drive sources. In addition, the interlocking mechanism tilts every other guide body in the same direction and tilts adjacent guide bodies in the opposite direction. By tilting the body in the opposite direction, items can be stored in the remaining even-numbered storage compartments, so that the deformation of the items will not be accumulated and the partition body will not be significantly deformed. Since there are no storage compartments, items can be reliably stored in all storage compartments.
