Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an empty box stacking machine for stacking transported empty boxes.

Conventionally, in this type of empty box stacking machine, a second empty box is placed inside the first empty box that has been transported so that the side surface of the second empty box is in contact with the bottom of the first empty box, and then , the third empty box was stacked with the opening facing down and the opening of the first empty box stacked together to form a set of three empty boxes, but this work was not done manually. Save,
This method has drawbacks such as the need for workers and the time-consuming task of disposing of empty boxes.

The present invention was devised in view of this point, and provides an empty box stacking machine that can facilitate processing of empty boxes.

One embodiment of the present invention will be described in detail below with reference to the drawings.

In the figure, the empty box stacking machine 1 is constructed as follows.

That is, the conveyance device 3 includes frames 5, 5 arranged in parallel with a slight inclination, and rotatable rotary rollers 7, 7, . ...
are pivotally mounted at appropriate intervals, and a plurality of empty boxes 9, 9, .

In the transport path of the transport device 3, there are empty boxes 9°9 in the lateral direction.
, . . , is provided with a reversing device 11 for reversing.

The reversing device 11 is configured as follows.

That is, on the support stand 13, there is a support part 17 that supports the idle rollers 15, 15 that are rotatable in the side direction of the conveyance device 3.
, 1γ are fixed.

Further, a motor 21 equipped with a rotary gear 19 that rotates at a substantially intermediate position between the idle rollers 15, 15 is fixed.

Further, a rotating drum 23 is provided above the support base 13 so that its axial direction is located in the conveying direction.
On the outer peripheral surface of 3, ring zones 25, 25 . and gear 27 are fixed.

The ring zone 25.25 rolls on an idler roller 15.15, the rotating gear 19 meshes with the gear 27,
The rotary drum 23 is rotated by driving the motor 21.

Furthermore, as shown in FIGS. 3 to 5, inside the rotating drum 23, four frames 29, 29, 29 fixed in the conveyance direction are provided in parallel, and each adjacent frame Rotating rollers 31° 31, . . . are rotatably provided between the rollers 29 and 29 at appropriate intervals in the lateral direction with respect to the conveyance direction.

That is, the frames 29, 29 and the rotating roller 3L
31°... are provided symmetrically on the upper, lower and both sides of the rotating drum 23.

Further, a guide plate 33 is provided above the conveyance rear side of the rotary drum 23.

A stopper 35 for locking an empty box is pivotably mounted on the guide plate 33.

Next, a stacking device 37 for stacking the transported empty boxes is provided below the inclined end portion of the transporting device 3.

A bottom portion 39 of the stacking device 37 is provided appropriately below the conveying device 3, and is connected to the bottom portion 39 to
A conveying device 41 is provided for conveying a set of three empty boxes stacked in a direction perpendicular to .

In the above configuration, the first empty box 9 transported on the transport device 3 enters the reversing device 11, and while maintaining the attitude of the empty box 9a in FIG.
1, and falls from the conveyance terminal end while being guided by the guide plate 33, and is placed on the bottom 39 of the stacking device 37 in the attitude of the empty box 9a shown in FIG.

Next, when the second empty box 9 enters the reversing device 11, the stopper 35 rotates in the direction of arrow A in FIG. 2, and takes the position shown by the imaginary line, and the empty box 9 is locked.

Further, by driving the motor 21, the rotating gear 19 is rotationally driven, and the rotating drum 23 is rotated 90' via the gear 27.
Rotate and stop.

That is, it is stopped while maintaining the attitude of the empty box 9b shown in FIG.

Next, as the stopper 35 rotates in the direction opposite to the direction of arrow A, the empty box 9 is guided by the guide plate 33 and falls from the conveyance terminal end, and the empty box 9 is placed on the bottom 39 of the stacking device 37.
It is housed inside the empty box 9 while maintaining the posture 9b shown in FIG.

Next, when the third empty box 9 enters the reversing device 11, the stopper 35 rotates in the direction of arrow A in FIG.

Furthermore, the rotating gear 19 is rotationally driven by the drive of the motor 21, and the rotating drum 23 is rotated by 180° via the gear 27.
Rotate and stop.

That is, the empty box 9C is stopped while maintaining the attitude shown in FIG.

Next, as the stopper 35 rotates in the direction opposite to the direction of arrow A, the empty box 9 is guided by the guide plate 33 and falls from the conveyance terminal end, and is deposited on the bottom 39 of the stacking device 37 as shown in FIG. Maintain the posture of box 9C.

That is, the opening of the empty box 9a containing the second empty box 9b and the opening of the third empty box 9C are combined to form one set of three boxes.

The above-mentioned operations are performed repeatedly, and these series of operations are automatically controlled in a coordinated manner through an appropriate sensing device.

The set of three empty boxes stacked in the above manner is sent to the transport device 41 and stored in a warehouse or the like, or is loaded onto a truck or the like and transported as is.

As is clear from the above, according to the configuration of the present invention, empty boxes that are continuously transported by the transport device with the opening facing upward are
One of the empty boxes is passed through the reversing device with the opening facing up, the next empty box is rotated 900 degrees by the reversing device and passed through, the next empty box is rotated 180 degrees by the reversing device and passed through, and the stacking device is passed. Receive these three boxes in this order, store the next empty box in the empty box with the opening facing up, and align the opening of the next empty box with the opening of the empty box with the opening facing up. Can be matched.

Therefore, it is possible to save the effort of manually reversing the empty boxes and assembling the empty boxes, and it is possible to easily process the empty boxes.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented in other embodiments as well.
