Description

DETAILED DESCRIPTION OF THE INVENTION It is particularly intended to be able to automatically and orderly pack articles into paper boxes.

A common method of packaging gifts and food-related products is to pack each product into a presentation box, and the products are delivered to consumers via distribution channels while packed in the presentation box. For this reason, packaging materials are made of U#, which does not put a burden on them during distribution, has a certain degree of strength to prevent damage to belongings, is placed low, and is a source of pollution when released by consumers and becomes garbage. It is desirable that various requirements be met, such as not becoming Based on the above-mentioned process, cardboard and cardboard boxes are mainly used as packaging materials.By the way, the shape of paper boxes changes depending on the strength of the folds, hygroscopicity, and temperature. , easy l/4
It has a drawback. For this reason, it is not suitable for machines to automatically pack items such as gifts.
Most of the packing is done manually. In other words, if you simply try to pack the box with an automatic machine, the box will deform when you press the outer surface of the box during positioning, and the amount of deformation of the box will vary greatly depending on the strength and weakness of the folds when forming the bottom of the box. Because of the large size, the dimensional accuracy necessary to pack items in an orderly manner cannot be obtained, and the packing becomes messy, making it unsuitable as a gift. In extreme cases, the item may climb onto the edge of the box and crush the box. Of course, the effects of the box's hygroscopicity, temperature, etc. are also added to the above-mentioned deformation of the box.

SUMMARY OF THE INVENTION In view of the above-mentioned prior art, it is an object of the present invention to provide a method for packaging articles and its packaging, which can automatically and easily pack articles even in paper boxes. The method of the present invention for achieving such an object positions the box by bringing a positioning plate into contact with the inner wall of the box whose top surface is open, and lowers the article from above using the positioning plate as a guide to move the article into the box. The device, which has since passed away, consisted of a transfer device for horizontally transferring a box with an open top, a sensor for detecting the transfer position of the box, a positioning plate configured to move up and down, and It has a holding part that is arranged to move up and down separately from the positioning plate and holds the articles, and a stuffing machine (iii) provided above the transfer device, and a feeder that supplies the articles to the holding part. , based on the detection signal from the sensor, an In
In one step, the positioning plate is lowered and brought into contact with the inner wall of the box to position the box, and the holding part is lowered using the positioning plate as a guide to stuff the articles held by this holding part into the box. and a control device for controlling the stuffing machine.

Hereinafter, the present invention will be explained in detail based on the drawings.

Fig. 1 is a front view schematically showing an embodiment to which the present invention is applied, Fig. 2 (a) is a front view showing its detailed structure, and Fig. 2 Q)) is a side view showing its detailed structure. It is. As shown in these figures, a paper glaze 1 with an open upper surface is transferred horizontally by a belt conveyor 2, which is a transfer device. A stuffing machine 3 is installed above the belt conveyor 2, and this stuffing machine 3 has a positioning plate 5 that is moved up and down by an air cylinder 4, and a vacuum suction nozzle that is moved up and down by an air cylinder 6. It has seven parts (holding part). The article 9 fed by the vibrating feeder 8 is attracted and held by the vacuum suction pad 7. Sweet, the horizontal direction of the sum 1 (
The position (perpendicular to the transport direction) is defined by the guide plate 10. Note that the stuffing machine 3 can be moved in a direction perpendicular to the transfer direction, and its position can be adjusted.

The transfer position of the box 1 is detected by an optical sensor 11, and this detection signal is input from a detector 12 to a control device 13. The control device 13 controls the stuffing machine 3 and the belt conveyor 2 as follows based on the detection signal.

(1) The positioning plate 5 is lowered in synchronization with the transport speed of the box 1 and brought into contact with the inner wall of the box 1.

(11) At the point of contact, the belt conveyor 2 is temporarily stopped.

(iii) When the belt conveyor 2 is stopped,
The prize 9 suction pad 7 holding the article 9 is lowered.

At this time, the article 9 descends while sliding onto the positioning plate 5, so the positioning plate 5 functions as a guide.

0φ Position item 9 just before it is stuffed into box 1 &
Raise 5. This is to prevent the items 9 from getting in the way when packed.

() Pack the T+yIJ product 9 into the box 1, and then pull up the vacuum suction/gut 7.

(■1) Next, belt conveyor 2 k fl< rb+
H and transport the box-1 packed with articles 9.

(viD) The vacuum suction M pad 7 that has been pulled up holds the article 9 to be packed next.

(viiD Repeat steps (1) to (viD) below to perform packing work one after another.

On the other hand, if a vacuum suction vat 7' capable of holding two articles 9 is used as shown in FIG. 3, two articles 9 can be packed at the same time. In this case, the positioning plate 5
is formed into a U-shape so that two articles 9 can be guided simultaneously. In addition, as shown in FIG.
If the tip is bifurcated, one side is used as the contact part 5a that contacts the inner wall of phase 1, and the other side is used as the guide part 5b that guides the article 9, it is possible to accurately pack the VC article 9 in a place away from the inner wall. .

As explained in detail in conjunction with the embodiments above, according to the present invention, even if the box has large dimensional changes such as a paper box, the positioning plate can position the box based on the inner wall of the box. Moreover, since the articles are packed using the positioning plate as a guide, the articles can be accurately packed in predetermined positions within the box without climbing over the edge of the box or crushing the box. Thus, items can be packed automatically.
