Description

[Detailed description of the invention] The present invention relates to a conveyance device, and when a box material to be super-transferred is conveyed by a conveyance machine, the flaps are struck by a flap-beating mechanism provided below the conveyance path to remove entanglements between the flaps. However, it is an object of the present invention to provide a conveying device that ensures over-trapping.

For example, when a box material such as a cardboard box used for packaging products etc. is normally transported by a transport device, it is folded into a flat state and folded into a three-dimensional shape. Face the required areas using a face-to-face machine such as a gluing machine.

Among these steps, the overpassing has conventionally been carried out by inserting a specially shaped overpassing member provided on the side of the conveying device into the gap between the flaps.

However, with conventional devices, there is no particular problem when the box material is new, but when the box material is a used returnable box, the adjacent flaps become intricately intertwined with each other at the edges. For this reason, when super-crossing, it is not possible to insert the super-crossing member between the flaps, and this has the disadvantage that super-crossing may not be possible. .

In addition, a box material folded into a flat plate shape is conveyed through the air by suctioning the negative side using a vacuum suction pad, etc., and at the same time, the box material's own weight causes the box material to overflow other surfaces into a box shape. There is also a known conveyor, but like the above-mentioned conveyor, when the flaps of the box material are intertwined with each other, such as a returnable box, the - side of the box material remains attached to the other side. It had drawbacks such as sometimes being unable to super-translate.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the conveying device according to the present invention, and FIG. 2 is a perspective view of a state in which a box material is being conveyed by the conveying device.

In FIG. 1, the conveying device 1 includes a conveying machine 3 that suctions and conveys a box material 2 folded into a flat plate shape with a vacuum suction pad 3a, and a pair of conveying machines installed on both sides below a conveying path 4 of the conveying machine 3. It is composed of a flap striking mechanism 5.

Here, since the pair of flap striking mechanisms 5 have the same configuration, only the one visible on the front side is illustrated, and the other one is omitted.

The flap-beating mechanism 5 includes a hammer 6 for flap-beating that is pivotally supported on a shaft 6a provided below the conveyance path of the flap 2f of the box material 2, and a hammer 6 that is moved in a direction such that one end of the hammer 6 abuts the flap 2f. 6, a cam 8 whose peripheral surface abuts the other end of the flap 2f, and a motor 9 that rotationally drives the cam 8.

Incidentally, the motor 9 is shared by the left and right flap striking mechanisms 5 to save power.

In the case of this embodiment, eight cam grooves 8a are provided on the circumferential surface of the cam 8, and each time the other end of the hammer 6 engages with the cam groove 8a as the cam 8 rotates, the spring 7 The force causes one end of the hammer 6 to strike the flap 2f from below.

Here, the box material 2 consists of four surface parts 2p connected in a box shape and flaps 2f provided at the left and right ends of each surface part 2p.

In the case of this embodiment, the box material 2 used as a returnable box is folded into a flat plate and placed in a predetermined position in layers.

The conveyor 3 first moves above the box material 2 and descends until the suction pad 3a abuts against the negative surface 2p□ of the box material 2.

The suction pad 3a adsorbs the surface portion 2pt by negative pressure after coming into contact with the upper surface of the surface portion 2p□.

When the suction is completed, the suction pad 3 a rises together with the conveyor 3 and then moves laterally along a predetermined conveyance path 4 .

In this way, when the box material 2 passes directly above the flap-beating mechanism 5 as the transporter 3 moves laterally, the flap-beating mechanism 5 is activated.

As a result, the flaps 2f on both sides of the box material 2 are struck from below by the hammer 6.

Therefore, the two flaps 2f whose ends are entangled are removed from the entanglement by the vibrations applied by the hammer 6.

When the tangles between the flaps 2f are removed in this way, the box material 2, which had been kept flat by the tangles between the flaps 2f, has its own weight which causes the surface 2p other than the surface 2p1 sucked by the suction pad 3a to □
As shown in FIG. 2, the other surface portion 2p is box-shaped and exceeds the surface portion 2P.

The box material 2 that has been super-crossed in this manner is transported by a transporter 3 to the carry-in end of a chain conveyor (not shown) or the like, and placed on the conveyor.

In the middle of this conveyor, a flap folding device (not shown) and a facing machine (not shown) such as a binding machine or a gluing machine are installed, and the box material 2 is folded in flaps 2f in a predetermined order. Afterwards, a predetermined area where the articles are stored is shot.

In this way, the conveying device 1 uses the flap striking mechanism 5 to flap the flaps 2 while the box material 2 is being conveyed by the conveying machine 3.
Since the structure is such that the bottom surface of f is tapped, it is possible to remove the entanglement of the flap 2f, which is often found in used box material 2 as a returnable box, very easily.

In addition, in the case of this embodiment, the conveyor 3 transfers the box material 2 to the suction pad 3.
Since the box material 2 is configured to be adsorbed by a and transported through the air, the box material 2 can be easily lifted while removing entanglements between the flaps 2f, and therefore a special lifting device or the like is not required. can.

In the above embodiment, a used box material 2 is used as a returnable box, but the box material 2 may be a new one.

In the case of a new product, the flaps 2f are almost never entangled with each other, but the conveyance device 1 allows for more reliable overlapping.

In the above embodiment, the number of suction pads 3a used in the conveyor 3 is not limited to three, but may be one, two, or even four.
It may be more than one.

Further, in the above embodiment, the conveyor 3 is not limited to the suction pad 3a, but may also be a roller conveyor, a chain conveyor, a belt conveyor, etc. In that case, the overpass of the box material 2 is provided on the side of the conveyor. For example, this may be carried out using an S-shaped overpass member (not shown) or the like.

Further, in this case, it is possible to adopt a configuration in which the flap beating mechanism 5 is driven using the power of the conveyor drive motor, thereby making it possible to favorably simplify the device configuration.

Further, in the above embodiment, the flap striking mechanism 5 is not limited to the structure in which the hammer 6 is vibrated by a rotating body such as the cam 8, but may be configured to vibrate the hammer 6 by a reciprocating drive mechanism such as a piston-cylinder mechanism, for example. .

Further, the flap striking mechanism 5 may be configured to eject, for example, an air flow to the flap 2f to remove the entanglement, without using mechanical vibration of the hammer 8 or the like.

Further, in the above embodiment, the flap striking mechanism 5 is provided on both sides of the conveyance path 4, but one may be omitted and the flap striking mechanism 5 may be provided only on one side of the conveyance path 4.

As described above, the conveying device according to the present invention includes a conveying machine for conveying a flat box material to be super-transferred, and a conveying device provided below the conveying path of the conveying machine, so that the box material is conveyed by the conveying machine. Since it is comprised of a flap-beating mechanism that strikes the flaps from below to remove the entanglement between the flaps, for example, after being used as a returnable box, the box material that has been folded into a flat plate can be folded up again and reused. In such cases, when the transporter transports the box materials, the flap-beating mechanism taps the flaps from below to remove any tangles, making it extremely easy to unbox used box materials just like new ones. In particular, if a hanging conveyor with a vacuum suction pad is used as a conveyor, it is possible to remove entanglements and lift the box by its own weight. When a roller conveyor, chain conveyor, etc. is used, the flap-beating mechanism can be driven using the power of the conveyor drive motor, which has the advantage of simplifying the device configuration.
