Abstract

PURPOSE:To place a large number of articles in a box automatically by a method wherein plate shaped articles are piled up in order on an elevating table, a box is turned over and held upside-down, and after inserting plate shaped members in the box by ascending the elevating table, the box is turned by 180 deg. to make it stand normally. CONSTITUTION:At the tip end of a rotary frame 6 for an automatic packing device, a pair of chucks 7a, 7b are provided. A box 2 is carried in under an upside-down condition to a position 2A by a box carrying-in conveyor 8, and is chucked. When piled up plate shaped articles 1 are supplied on an elevating table 4 by an article supplying conveyor 9, the elevating table 4 is driven and reached a position 4', and an accumulation 1 of the plate shaped articles which are loaded is inserted in the box 2. The box, in which the plate shaped articles 1 are placed, comes to a position 2C accompanied with a 90 deg. turning of the rotary frame, further reaches a position 2E, and is turned over by 180 deg. and becomes upside-down. When the elevating table 4 is lifted from the box at the position 2E, a condition, where the plate shaped articles 1 are placed in the normally standing box, is given. Therefore, a large number of articles can be automatically placed in a box by a motion with one cycle.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for automatically placing a plurality of articles into a box (eg, a cardboard box).

[Conventional technology]

BACKGROUND ART In order to store and transport a large number of articles of the same shape and size, it is widely practiced to store a plurality of articles in a single box.

The above-mentioned packaging work was originally performed manually by workers.

In recent years, research has been conducted on box-packing work using robot hands, but it is not possible to store Setsubun items all at once into boxes, and one or more items must be packed multiple times to fill boxes. The same operation continues until the box is full.

[Problem to be solved by the invention]

When storing a large number of articles in a box, if the articles are in the form of powder or granules, so-called powder transport technology or a chute can be used, so there is no great difficulty.

However, as shown in FIG. 10(A), for example, the work of putting a large number of plate-shaped articles 1a, lb, etc. into a box 2 and storing them as shown in FIG. 10(B) is difficult. It cannot be done with one action.

As a technique for automating such work, it is common to transport the sheets one by one using a vacuum suction pad and stack them into the box 2 from the bottom.

However, with this prior art, eight plate-shaped articles 1a to 1
When trying to store h into the box 2, the operation of suction holding → insertion into the box → suction release must be repeated eight times, which is inefficient.

If this work is to be carried out all at once, it is necessary to tie it up or wrap it with tape as shown in FIG.

Wrapping with straps or tape in this manner wastes packaging materials, wastes packaging time and labor, and increases the number of unpacking steps.

Platy items are placed in the box 2 without stringing or wrapping with tape like this.
When storing the plate-shaped articles 18 to 1h in a container, it is practically impossible to hold the plate-shaped articles 18 to 1h by a pair of hooks 3a and 3b as shown in FIG. The reason for this is that the hooks 3a, 3b cannot be pulled out after the items to be stored are suspended into the box 2. When trying to make it possible to pull out the hooks 3a and 3b, the box 2 and the articles 1a~
1h must be significantly increased.

The present invention has been made in view of two circumstances: there is no need for stringing or wrapping with tape, there is no need to provide an excessive gap between the stored items and the inner surface of the box, and it is possible to store a large number of items. It is an object of the present invention to provide a device that can automatically store items into a box in a single operation.

[Means to solve the problem]

FIG. 9 is an explanatory diagram of the basic principle of the method of the present invention.

As shown in FIG. 9(A), the plate-shaped articles 1a+1b to 1h are stacked on the lifting table 4 in a uniform manner.

=4 The box 2 is held upside down and directly facing the vertical position of the lifting table 4.

As shown in FIG. 2B, the lifting table 4 is raised and the plate members 18 to 1h are inserted into the box 2.

Then, the box 2 is rotated 180 degrees as shown by arrow R and flipped upside down, so that the box 2 stands upright as shown in FIG. 2(C).

As specific requirements for configuring an automatic cartoning machine based on the basic principle shown in FIG. a chuck means provided near the tip and supporting the opening of the box toward the rotational axis; a table that is reciprocally driven and guided in a direction toward and away from the box; a box carrying conveyor that supplies boxes to the chuck means when the arm is in an upwardly facing position; an article supply conveyor for supplying stacked plate-like articles onto a table; and an unloading conveyor for receiving and conveying boxes released from the chuck means when the arm is in a downward position. It is characterized by having the following.

[Effect]

According to the procedure shown in FIGS. 9(A) to 9(C), there is no need to tie strings or wrap tape around a large number of plate-shaped articles 1a to 1h, and there is no need to tie strings or wrap tape around a large number of plate-shaped articles 1a to 1h. There is no need to create an excessive gap between the boxes, and multiple items can be stored in the box 2 in one cycle.

In the principle explanatory diagram of FIG. 9, the table 4 is raised and lowered, but the box 2 may also be raised and lowered. In short, the same action and effect can be obtained by inserting it into the box 2 and moving the table 4 up and down relatively.

Since the chuck in the above configuration is attached to the rotating arm 11, it chucks the box and rotates the box in the direction of the arrow R in FIG. Since they approach and separate while maintaining parallelism, they serve as the lifting table 4 in FIG. 9.
