Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a flat-folded container blank of cardboard-like material having a sleeve-shaped central part with four sides, a central lid piece, two side lid pieces and a bottom part. The present invention relates to a method and apparatus for forming a box-like container from.

The present invention provides for the formation of box-like containers of the type described above in a series of different sizes on a single machine.

In machines for storing, counting and packaging coins there are special requirements for equipment having the above-mentioned functions. These machines handle large numbers of coins and are often used, for example, in banks, post offices and supermarkets.

Such machines package a predetermined number of coins of one type in a tube, seal the ends of the tube to form a certified unit of, say, 100 coins, and transport this unit between a bank's vault and teller counter. and between the main office and branch offices.

To facilitate the handling of the above-mentioned coin tubes, the tubes are usually packed in cardboard boxes, for example 2503 EK for 10 Ore coins (50 tubes of 58 ε each).
, 50O38K with 50 ole coin (20 of 253EK each)
tubes), 100O3EK for 1 kroner coin (20 tubes of 5O3BK each), 2 tubes for 5 kroner coin
00O3BK (10 tubes of 20O3BK each)
It forms a certified unit. Each coin tube has a considerable mold cavity, and transport and handling of the cardboard is done by manual labor. Rationalization by introducing automatic packaging equipment for coin tubes requires a very large investment in capital and protected area, since different cardboard boxes are used for different currencies. On the other hand, changing the conventional operation in distribution systems using various cardboard boxes is considered to have considerable disadvantages.

The object of the invention is to provide a method and a device with which different cardboard boxes can be assembled automatically from cardboard blanks of different dimensions in a single device and without the need for modifications. It is.

To achieve this objective, the method according to the invention comprises bending a flat cardboard blank by approximately 90° around an imaginary axis coaxial with the folding line of the lid pieces to bend one of the central lid piece and one of the side lid pieces. Bend the remaining lid piece along the bending line in the opposite direction away from the plane of the central part, and bend the remaining lid piece along the bending line in the opposite direction away from the plane of the central part, so that the edge of the plane is bent. It is characterized in that the central and bottom parts are assembled by moving towards each other to form a substantially rectangular box.

According to a preferred embodiment of the invention, the blank is bent in a cradle surrounding the bottom and central part of said blank.

Preferably, during rotation of the cradle, the fold line of the lid piece is moved in parallel over a distance that at least corresponds to the linear length of the central lid piece that projects from the cradle.

Furthermore, it is advantageous to withdraw the blank from the cardboard blank magazine as it enters the cradle and during rotation of the cradle.

According to another embodiment of the invention, before assembling the central part and the bottom, a cardboard blank with a lid bent away from the plane of the central part is displaced from the cradle.

The device for carrying out the method according to the invention comprises first hook means for drawing the blank into the pivoting cradle, means for displacing the pivoting cradle in parallel simultaneously with the pivoting, and first hook means for bending one of the lid pieces of the blank. It is characterized in that it comprises two hook means, means for drawing the blank laterally from the immobile cradle, and pressing means for raising the central and bottom parts of the blank.

An embodiment of the invention will be described with reference to the accompanying drawings.

The illustrated cardboard blank 10 comprises a sleeve-shaped central part 11 with four sides, a central lid piece 12, two border or side lid pieces 13 and a bottom part 14 (see FIG. 9). . In the illustrated example, the bottom part 14 comprises four cardboard pieces 14a, which automatically cooperate during assembly;
They are configured to interlock with each other by a self-closing action to form a rigid bottom.

The magazine 15 is configured to receive a number of flattened cardboard blanks IO, as shown in the left-hand part of FIG. In the example shown, the blank 10 is a lid piece 12.1
3 is held vertically downward by a tensioner 16, and the tensioner acts to press the stacked plurality of blanks toward a support plate 17 with slits. Two downward feed hooks 18, 19 are provided vertically displaceable along the slit up and down.

The downward feed hooks 18, 19 are attached to the support plate 1 in the illustrated position.
The cardboard blank can be gripped by engaging the lid piece 13 and the middle part 11 of the cardboard blank located closest to the support plate 7, and the cardboard blank can be held in the magazine 1.
5 through the delivery slit 20 and vertically displaced downward.

The vertical distance between the downward feed hooks 18, 19 corresponds to the height of the side lid pieces 13 and all have the same height, regardless of the price of the coins for which the cardboard box is used.

While the cardboard blank is lowered vertically through the slit 20 by means of a downward feed hook, it is moved up to the level of the folding line 22 of the lid piece into the slotted U-shaped pivoting cradle 2.
Enter within 1. The middle part 11 of the box blank has different dimensions depending on the price of the coin, which means that the distance that the blank is lowered into the cradle 21 differs depending on the price of the coin for which the blank 10 is used. However, since the height of the side lid pieces is always the same, there is no need to make any changes to the machine for different types of cardboard blanks, and the stroke of the downward feed hook is midway between the most commonly used types of cardboard blanks. It is adjusted to the height of the part.

As a result, the downward feed hooks 18, 19 will rise somewhat more than necessary for cardboard blanks with a low intermediate height.

The rotating cradle 21 is rotated and simultaneously displaced by a link mechanism shown in FIGS. 1 and 3. This link mechanism includes a link arm 23, which links the magazine 1.
It is connected between a fixed pivot point 24 on 5 and a displaceable pivot point 25 at the lower end of the rotating cradle 21 . The link arm 23 can be rotated back and forth by an actiniator arm 26.

Guide means 27, for example rollers, are provided to guide the cradle 21 during this rotation, and are arranged to allow a substantially vertical translation of the folding line 22. As a result of these combined movements, the cradle is rotated through substantially 90° around the guide means 27 while at the same time pulling on the lower end of the cardboard blank.

During the above-mentioned operation, the cardboard blank 10 is completely pulled out of the slot 20 of the magazine, during which time the central cover piece 12 and one of the side cover pieces 13 are abutted against a folding support (not shown) to extend the length. It is maintained in a state in which the direction is upward and inclined at a predetermined angle with respect to one side of the plane of the intermediate portion, that is, in a state in which it is bent along the bending line 22. The remaining side lid pieces 13 are maintained with their lengths aligned with the plane of the intermediate portion as shown in FIG.

The lid folding hooks 28 are configured to fold the remaining side lid pieces 13 in the opposite direction away from the plane of the intermediate portion, that is, downwardly along the folding line 22 as shown in FIG. . Therefore, the combination roll 29 bearing an eccentric journal is positioned laterally beyond the previously folded lid piece 13, and the lid piece 13 is gripped between the roll 29 and a support strip (not shown).

Next, as shown in FIG. 8, the combination roll 29 is operated by a reciprocating mechanism (not shown) to form the cardboard blank 10.
is laterally displaced from the cradle 21.

When the cardboard blank reaches the assembly position, the combination roll 2
9 from the lid piece 13. Finally, the edges of the plane are moved closer to each other by the assembly hook 30 so that the middle part 11 and the bottom 12
and assemble. The assembly hook 30 can be displaced towards the left in FIG. 9 until a substantially rectangular cardboard box has been formed with the lid piece folded outwards. The cardboard box thus assembled is ready to be filled with the desired contents and the device can repeat the cycle of operation to assemble the next cardboard box.

The method described above and the device for carrying out the method allow for the quick and reliable assembly of cardboard blanks of various sizes within a minimal footprint, and do not require modification of the construction of the device depending on the type of cardboard blank. There is no.

The present invention is not limited to the above-mentioned examples, and various changes can be made within the scope of the present invention.

For example, the means for handling cardboard blanks can also be configured in many other ways. The method and device according to the invention can also be applied to other types of packaging machines, for example cars of various types.
Of course, the present invention can be applied to automatic packaging machines.
