BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrying device for carrying an article placed on a carrying platform such as a pallet or tray by using a conveyor. In particular, the transporting device of the present invention bends the transport path in the cross direction without changing the posture of the product in a certain direction when transporting the product such as a take-up roll, which is likely to be damaged and may be rolled during the transport. It is also applied when the transport route is branched.

[0002]

2. Description of the Related Art Conventionally, in the transportation of articles by a conveyor, when the transportation paths are bent or branched in the intersecting direction as described above, the conveyors are arranged in the intersecting directions and the articles are hoisted by a hoisting device. Or, kicking it out with a kicker, transferring it from one conveyor to the other, and carrying it in the crossing direction with the other conveyor.

[0003]

However, when the articles are transferred from one conveyor to the other conveyor by the lifting device, the lifting device provided above the transfer position between the conveyors has a large-scale structure. Also, an article holding mechanism,
It has a complicated structure such as a lifting mechanism and a moving mechanism. Furthermore, since the stability of the suspended article is not so good, the position of the transported article tends to be inaccurate, and it is difficult to transport the article in a short time.

Further, when an article is kicked out and transferred by a kicker, the article is easily damaged. Also, it may not be transferred to the correct position.

It is an object of the present invention to provide a carrying device which can reliably change the carrying direction of an article in a crossing direction in a short time when the article is carried by a conveyor while keeping the posture of the article in a constant direction. I am trying.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. The carrying device in this embodiment is applied to a take-up roll carrying line.

Reference numeral 1 in each figure denotes an article to be conveyed. In this embodiment, a take-up roll, 2 is a carrier for carrying the take-up roll 1, 3 is a take-up roll 1 in a radial direction, That is, line conveyors 4 that convey the take-up roll 1 at right angles to the longitudinal direction are cross conveyors that intersect the line conveyor 3 and convey the take-up roll 1 in the longitudinal direction.

The winding roll 1 is obtained by dividing a strip-shaped sheet into a roll shape in a winding device with a slitter (not shown) and is generally easily scratched and rolled.
Therefore, in order to prevent damage during transportation and ensure stability, the transportation is carried on the transportation platform 2.

Since the individual lengths of the take-up roll 1 are various, preparing a carrier bed according to the length of the take-up roll 1 will be troublesome in handling and storing it. In order to eliminate this trouble, only one type of carrier bed 2 of the same size is prepared, and each of them has compatibility. In addition, the winding roll 1 and the winding roll 1
In order to carry the data related to the above, the storage medium 2a that can read and write data in a non-contact manner is held.

In FIG. 1, the winding roll 1 is supplied from a conveyor 5 to a cross conveyor 4 in a posture in which the longitudinal direction thereof is directed to the left and right, and from the cross conveyor 4 the line conveyor 3 is fed.
And transferred to the downstream of the transfer line. Even after being transferred to the line conveyor 3, the posture in which the longitudinal direction is directed to the left and right is not changed.

The winding roll 1 supplied to the cross conveyor 4
If the length is short, it is supported by one luggage carrier 2, and if the length exceeds a certain value, it is supported by two luggage carriers 2.

The line conveyor 3 is a chain conveyor and is provided with a plurality of (four in the embodiment of FIG. 1) beam members 6 extending in the carrying direction in parallel and at equal intervals. Around the beam member 6, endless chains 7 are provided so as to form elongated loops.

The interval between the endless chains 7 adjacent to each other is set to be narrower than the length of the carrier 2 so that one load carrier 2 can be supported by the adjacent endless chains 7.
Further, when the winding roll 1 is placed on the two loading platforms 2, the two loading platforms 2 are individually attached to the left and right two sets of the endless chains 7 which are one set of the outermost row and the inner row adjacent thereto. Therefore, the space between the two cargo beds 2 is adapted to the space between the two left and right endless chains 7.

Each endless chain 7 can be circulated around the beam member 6 in synchronization with each other by being driven by a driving device (not shown). If necessary, a narrow endless belt may be used instead of the endless chain 7.

The cross conveyor 4 is a belt conveyor, and avoids the endless chains 7 from moving downward so that a conveying surface 8a is formed between the endless chains 7 of the line conveyor 3 as shown in FIG. It is equipped with an endless belt 8 that can be circulated.

The endless belt 8 is wound around a group of guide rollers provided on the frame 9 and is circulated by a drive motor 10.

The frame 9 is cut out at a portion intersecting with the endless chain 7 of the line conveyor 3, and the support base 11 is provided.
It is provided so that it can be raised and lowered. In this embodiment, the support base 1
It is fixed on a guide rod 12 which is slidably held on 1. Then, it is driven up and down by the lifting mechanism 13.

The lifting mechanism 13 includes a fluid pressure cylinder 14.
And a pair of links 15a and 15b and a connecting rod 17 for keeping the posture of the frame 9 in the vertical direction. Then, when the frame 9 is driven to raise the crossing conveyor 4, the conveying surface 8a of the crossing conveyor 4 is moved to the line conveyor 4
It can be placed at a raised position, as shown in FIG. 2, which is higher than the transport surface 7a. Further, when the crossing conveyor 4 is lowered, the carrying surface 8a becomes lower than the carrying surface 7a of the line conveyor 4, and the crossing conveyor 4 can be placed at the lowered position as shown in FIG. The lifting mechanism 13 may be any one other than this embodiment as long as it has such a function.

Next, the operation of the carrier device in the first embodiment will be described.

When the take-up roll 1 placed on the loading platform 2 is conveyed in the longitudinal direction by the conveyor 5 and supplied to the crossing conveyor 4, the crossing conveyor 4 is placed in the raised position by the elevating mechanism 13 and the take-up roll 1 is taken up. 1 is carried together with the loading platform 2 and is positioned immediately above the line conveyor 3 as shown in FIG. FIG. 2 shows a case in which the take-up roll 1 is supported by two loading platforms 2. When the winding roll 1 is supported by one loading platform 2, the loading platform 2 is supported by two inner rows of endless chains 7. Position above.

When the take-up roll 1 is positioned right above the line conveyor 3, the elevating mechanism 13 moves the crossing conveyor 4 to the lowered position. Then, the loading platform 2 on which the winding roll 1 is placed is placed on the endless chain 7 of the line conveyor 3 as shown in FIG.

When the loading platform 2 is placed on the endless chain 7, the line conveyor 3 starts transporting and transports the winding roll 1 together with the loading platform 2.

According to this embodiment, since the cross conveyor 4 is a belt conveyor, there is no need for a transmission device for driving each roller unlike the roller conveyor, and in addition, in order to increase the friction on the roller surface. It is not necessary to wind the roller with rubber.

A second embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a partial side view of the carrying device, and FIG. 5 is a partial plan view. The crossing conveyor 4 in FIG. 4 takes out the winding roll 1 conveyed by the line conveyor 3 from the line conveyor 3 and supplies it to another processing device such as a small slitter or a conveyor or rack for storing the winding rolls. Then, the winding roll 1 processed or stored there is returned to the line conveyor 3 again.

In the cross conveyor 4, the height of the frame 9a on the downstream side in the conveying direction of the frames 9a and 9b on both sides of the endless belt 8 is higher than the height of the other frame 9b. Then, the elevating mechanism 13 uses the dual process cylinder device 14 operated by the pressure fluid to lower the crossing conveyor 4 such that the conveying surface 8a and the upper ends of the frames 9a and 9b are positioned lower than the conveying surface of the line conveyor 3. The position and the transport surface 8a and the frame 9 as shown in FIG.
The upper end of b is lower than the transfer surface 7a of the line conveyor 3, and the upper end of the frame 9a is the transfer surface 7a of the line conveyor 3.
It can be attached to a first raised position which is higher and a second raised position where the upper ends of the transport surface 8a and the frames 9a and 9b are higher than the transport surface 7a of the line conveyor 3.

When the take-up roll 1 is taken out from the line conveyor 3, the longitudinal conveyor 4 is attached to the first elevated position by the elevating mechanism 13.

In this state, when the winding roll 1 placed on the bed 2 is conveyed by the line conveyor 3, the bed 2 passes through the upstream frame 9b of the cross conveyor 4 and reaches right above the cross conveyor 4. However, since the downstream frame 9a projects above the transport surface 7a of the line conveyor 3, it cannot hit and pass the downstream frame 9a. When the front surface of the loading platform 2 hits the downstream frame 9a, the line conveyor 3 stops the transportation after a while. The state of the loading platform 2 at this time is shown by a solid line in FIG.

When the line conveyor 3 stops conveying, the elevating mechanism 13 moves the cross conveyor 4 to the second elevated position. Then, the loading platform 2 is placed on the transport surface 8a. afterwards,
The winding roll 1 is conveyed by the cross conveyor 4 together with the loading platform 2 and taken out.

When the winding roll 1 is supplied onto the line conveyor 3, the crossing conveyor 4 is moved to the second position by the lifting mechanism 13.
The take-up roll 1 is conveyed in the direction opposite to that at the time of taking it out in the state where the take-up roll 1 is attached to the take-up roll 1 immediately above the line conveyor 3, and then the conveyance is stopped. Then, when the conveyance is stopped, the lifting mechanism 13 is set to the lowered position.
After that, the winding roll 1 is conveyed by the line conveyor 3 as in the first embodiment.

According to the carrying apparatus of the second embodiment, even when the cargo bed 2 being carried by the line conveyor 3 is out of the normal position for some reason, for example, as shown by the chain line in FIG. By once applying the loading platform 2 to the downstream frame 9a of the cross conveyor 4, the loading platform 2 can be aligned and then transported as shown by the solid line in FIG. Therefore, for example, it is possible to prevent troubles and the like caused by the improper position of the bed 2 during the processing and handling of the winding roll 1 on the downstream side of the automated winding line. Note that a stopper may be provided on the frame 9a, and instead of the frame 9a, the stopper may be used to prevent passage of the cargo bed 2.

The present invention has been described above with reference to the two embodiments, but the embodiments can be variously changed within the scope of the gist of the invention.

For example, the article is not limited to the take-up roll.
Further, as the cross conveyor 14 in FIG. 1, a chain conveyor or a roller conveyor may be used instead of the belt conveyor. The elevating mechanism may elevate the line conveyor 3 in FIG. Further, the belt conveyor 4 of FIG. 1 may be used as a first conveyor in the main conveyance path, and the chain conveyor 3 of FIG. 1 may be used as a second conveyor in taking out and supplying articles from the main conveyance path. Further, the crossing conveyor 4 in FIG. 1 may be capable of reverse conveyance, and the loading platform 2 sent from the line conveyor 3 may be taken out and supplied to the conveyor 5.

[0036]

According to the present invention, when an article is conveyed to the intersection of two conveyors, the conveyor surface of the conveyor to be conveyed next in the intersecting direction is the conveyor surface of the conveyor that has conveyed the article to the intersection. The higher position causes the article to be transferred onto a conveyor that is then conveyed in the cross direction.
As a result, even an article having a long length and a large weight can be placed on the conveyor in the intersecting direction reliably and in a short time while keeping the posture of the article in a fixed direction and without damage.

When used with the carrying device of the present invention, the carrying amount of the carrying line can be increased. Further, since it is not necessary to provide a large-scale device for transferring articles as in the conventional case, the occupied space can be small. Therefore, for example, it becomes easy to set the transport path so as to sew between the existing devices, and the floor area in the factory can be effectively used.
