Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for conveying cardboard produced in a cardboard box making machine.

It is desirable for this type of transport device to have a simple mechanism, but it should be possible to easily take out the cardboard being transported for inspection, etc., as well as to prevent the cardboard from lifting during transport and to prevent the glued portion from peeling off. It is necessary to meet the following requirements.

An object of the present invention is to provide a corrugated board conveying device that can appropriately convey manufactured corrugated cardboard.

A feature of the corrugated board conveying device according to the present invention is that it includes a conveyor disposed between predetermined positions, and a free roller juxtaposed generally parallel above the conveyor, making the free roller adjustable up and down and in a direction perpendicular to the conveyor; The free roller can be lifted quickly if necessary.

Next, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 6, this conveying device is basically a conveyor on which the corrugated boxes are placed and transported, - in this embodiment a roller conveyor (1), arranged generally parallel above the conveyor. It consists of a row of free rollers (2). The conveyor (1) is installed approximately horizontally on the machine frame (3) and is placed at a predetermined position. Each roller of the conveyor is driven by a motor (5) via a suitable transmission member (4). The free rollers (21 may be provided as one group, but are preferably divided into a plurality of groups as shown in the figure, and in this case, the free rollers of each group rotate around the support frame fGl for each group. They are freely installed, and each inlet end is slanted upward to facilitate the introduction of cardboard.

As is clear from FIG. 6, preferably the free roller (
2) are provided in pairs.

In order that these free rollers (2) can be adjusted up and down, a support frame (6) for the free rollers is installed at one end of a plurality of arms (7), each arm (7) being connected to a support (8) at the other end. A pivot mechanism for the arm (7) is provided. In the illustrated example, this pivot mechanism has a horizontal shaft (1o) with a manually operated handle (9) at one end, and a horizontal shaft (1o) with a manually operated handle (9) at one end.
A vertical shaft (12) interlocked with the horizontal shaft (10) through a pair of bevel gears installed in the gear box (formerly) into which the other end of the shaft (0) is inserted and provided along the support (8); The arm (the interlocking shaft (I3) to which one end of the sword is pivoted and the vertical shaft (121)
Consists of a pair of bevel gears (+41, +151) that interlock the arm (7).By operating the handle (9), the horizontal axis (00), the vertical axis (12), and the interlocking shaft (13) are rotated via the bevel gear to move the arm (7). Although it is designed to pivot,
Such an arm pivoting mechanism may use other mechanisms,
Furthermore, it is not a matter of course that automatic operation using an electric system using a motor may be used instead of operation using the handle (9).

Furthermore, this conveying device allows the position of the group of free rollers (2) to be adjusted laterally, that is, at right angles to the direction of conveyance by the conveyor (1), so that each arm (7) has a sliding A slider (I6) is freely installed, and the slider (I6) is clamped at an appropriate position on the arm (7) by a clamp handle (171).The support frame (6) of the free roller (2) is attached to the slider (I6). ). Preferably, as shown in FIG.
) is pivoted to the slider (16) by the bin r6').
In that case, the free roller (2) maintains a vertical state due to its own weight and swings to follow the cardboard being conveyed.

Furthermore, if desired, wheel conveyors (18) are provided on both sides of the conveyor (1).

Furthermore, this device is connected to the pivot end of the arm A t7),
A preferred form of the actuating device includes an actuating device for rapidly lifting the arm (7), as shown in FIG. 4, a weight (20) connected to the arm (7);
As shown in FIGS. 5 and 6, the release device consists of a link mechanism equipped with a connecting bottle (21) and a release pedal [22] at one end for operating it, as shown in FIGS. 5 and 6. C23). In this embodiment, the bottle (21) is attached to a mounting member C24 fixed to the interlocking shaft (13).
), and the arm (7) is attached to the interlocking shaft (13).
is fixed to the bearing c25) installed in the connecting bin f2
1) is partially inserted into the hole of the bearing (25), thereby connecting the arm (7) to the pivot mechanism. Weight (2o
) is connected to bearing r25). The bottle (21) is always pushed towards the insertion side by the spring c26). The upper end of the link mechanism is a cam (27), and a bottle (
The end (21') opposite to the insertion part of 21) is engaged, and when the pedal (22) is depressed, the bottle C21) is pulled out, and the arm +7) fd becomes freely rotatable with respect to the interlocking shaft (13). It is lifted by a weight (2o).

Of course, it is clear that this actuating device can also be constituted by other mechanisms, for example by an air cylinder [28] as shown in FIG. In this case, the air ring t28) is attached to the mounting member (2) of the bearing c25).
9) and the mounting member (3o) of the bevel gear (15), and when the air cylinder 128) is retracted, the arm (
7) is pivoted upwards and the free roller (2) is lifted.

During operation, the total gap between the conveyor (1) and the free roller (2) is set to an appropriate value in advance based on the thickness of the cardboard and the conveyance speed. Therefore, operate the handle (9) to connect the interlocking shaft (I3).
The arm (7) is pivoted via the mounting member (24), the connecting pin "21" and the bearing C25), and the height of the free roller (2) supported at the tip of the arm is adjusted.

As shown in Figure 6, it is preferable that the free roller (2) is applied to the glued part of the cardboard (A), so loosen the clamp handle θη and adjust the shape of the cardboard as shown in Figure 6. Accordingly, the slider (16) is moved along the arm (7) and clamped at an appropriate position.

The corrugated boxes manufactured by the box making machine are sent in a partially overlapping state, but are pushed down at the feeding end of the free roller (2), and in the pushed down state are transferred to the free roller of the conveyor (1). (2) and transported between the two. Therefore,
During transportation, the glued parts of each cardboard (Al) are kept in a good adhesion state and are prevented from peeling off.Furthermore, the folds at the folded parts are also kept in a folded state, so that they can be transferred to the next process, such as bundling. Sent on time.

In order to inspect or remove damaged cardboard during transport, all you have to do is step on the release pedal (22), which pulls out the connection pin (21) via the link mechanism 123), so the arm ( 7) and the interlocking shaft (13) are uncoupled,
The arm (7) pivots upwards due to the weight (20) and rapidly lifts the free roller (2). Therefore, it can be easily taken out to the corrugated pole. Note that if the support frame (6) is made plural and the free rollers (2) are divided into a plurality of groups, one area of the free roller (
2) can be lifted up, making operation easier.

In the above embodiments, a roller conveyor is used as the conveyor (1), but this conveyor may be another type of conveyor, such as a belt conveyor.

As described above, according to the present invention, the cardboard is conveyed while being held between the conveyor and the free rollers thereon. Therefore, the cardboard is subjected to a certain degree of pressure, and the glued portion can be appropriately pressed, making the gluing even more secure and preventing the cardboard from lifting. Furthermore, the cardboard boxes being transported can be easily taken out for inspection or to eliminate defective products.
