Description

[Detailed description of the invention] This invention is a stand-up system used to automate the packaging of electrical appliances such as refrigerators and washing machines, and other various products that are heavy and difficult to overturn. This relates to a type wrap-round caser.

Conventionally, the method used to pack electrical appliances such as refrigerators and washing machines, or other heavy items involves loading product B into the box from above box A1 with its bottom folded, as shown in Figure 1. There is a hanging type in which the product is stored by hanging it with a crane, etc., a covering type in which the bottomless box body A2 is fitted from above onto the product B supported from the bottom as shown in Fig. 2, and the bottom flap is folded; As shown in the figure, a blank sheet is punched and formed in advance to be assembled into a box body, and product B to be packed in a box is lowered from above A5. There was a wrap-up ceremony, etc.

However, these methods have the following problems.

First, in the hanging type shown in Figure 1, heavy products are hung and stored inside the box, which increases the process of hanging the products even though the work is dangerous. The packaging process is complicated and requires strong power, and furthermore, when the difference in size between the inside of the box and the product is small, insertion is difficult and automation is difficult.

Next, in the case of the fitting type shown in Fig. 2, like the above-mentioned hanging type, it is difficult to fit the box and automation is difficult if there is a small dimensional difference between the box internal dimensions and the product. However, the device is complicated because the box is sealed using the bottom flap.

The horizontal wrapping type shown in FIG. 3 is inconvenient in the case of seasonal products such as kerosene stoves, which require loading and unloading from the side because the packaging shapes are different.

This invention was devised in order to improve and eliminate the above-mentioned drawbacks of the conventional method.The key points of this invention are: (a) Feed the blank sheet in an upright position.

(b) Pushing the blank sheet into the molding guide of the reciprocating swinging device using the product as a pusher.

This covers three sides of the product.

(C) Swinging the molding guide horizontally using a reciprocating swinging device.

As a result, the fourth side of the product is covered, and the packaging of the product and the making of the box excluding the upper and lower flaps are performed at the same time.
