BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor belt for changing the conveying direction. More specifically, the present invention relates to an apparatus for transferring various articles on a conveyor, which is installed at a connection point of two or more conveyors having different traveling directions and which transfers articles to be conveyed while changing the conveying direction.

The field of use of the present invention includes, in addition to the transportation of corrugated cardboard sheets, the transportation of articles in a distribution warehouse, but is not limited to these, and any article can be transported by a conveyor. It can also be applied in the field.

2. Description of the Related Art In a corrugated board factory, a corrugated board must be transported between a corrugator that manufactures corrugated board and a plurality of box making machines that perform printing and box making on the corrugated board. Forklifts and electric traversers have been conventionally used for transportation. However, this system has the drawback of low processing capacity. In other words, if there is one forklift or traverser, it takes time to make a round trip, and if there are two or more forklifts or traversers, in order to avoid collision on the way home after one starts, This is because the use of the second unit was greatly restricted.

In view of such circumstances, the inventor of the present invention has already provided an automatic conveying device using a roller conveyor as a highly efficient conveying device for corrugated cardboard sheets (Japanese Patent Application No. 3-75954).
issue).

The device of Japanese Patent Application No. 3-75954 is a combination of roller conveyor units R1 and R2 as shown in FIG. 6, and in this device, the conveyance can be performed only by the forward movement of each conveyor unit, and the forklift and traverser can be used. The time required for the return movement and the waiting time for avoiding the collision, which were required for the above, is no longer required, and the transfer capacity is greatly improved.

[0006]

However, even in the above-mentioned apparatus, when the corrugated sheet S having a relatively narrow width is piled up and conveyed, since the rollers have a cylindrical shape, the conveyor surface has irregularities. However, there was a problem that it was easy to fall when changing directions. Therefore, at present, a veneer board is laid underneath, cardboard sheets are stacked on top of it, and conveyed by a roller conveyor.

However, laying veneer boards one by one is labor-intensive and inefficient, and laying veneer boards with an automatic machine is too costly for equipment, which is not practical in either case. is there.

In view of such circumstances, it is an object of the present invention to provide a device which can convey and change the direction of stacked corrugated cardboard sheets without laying down a plywood board.

[0009]

SUMMARY OF THE INVENTION A belt conveyor device for changing the conveying direction according to the present invention comprises a plurality of short and wide traveling belt conveyors arranged in series at intervals in the feeding direction, and a plurality of long and narrow delivery belts. The conveyors are arranged in parallel between the traveling belt conveyors so as to be orthogonal to the feeding direction of the traveling belt conveyors, and the upper surface of the payout belt conveyor is located at a position higher and lower than the upper surface of the traveling belt conveyor. It is characterized by comprising an elevating device for elevating.

[0010]

In the present invention, articles to be conveyed such as corrugated cardboard sheets received from the front and rear feeders are further fed by the traveling conveyor to be moved to the vicinity of the center of the traveling conveyor. Then, the payout conveyor is raised to drive the payout conveyor. Then, the article to be conveyed is sent out in the traveling direction of the payout conveyor. Since the delivering conveyor is orthogonal to the traveling conveyor in the feeding direction, the articles to be conveyed are delivered laterally from the main conveying route by the feeding. When the payout operation is completed, the payout conveyor descends and stands by so that the next traveling conveyor can carry it.

The traveling conveyor and the payout conveyor according to the present invention are belt conveyors for carrying and carrying articles to be conveyed on a belt. Since the belt surface has no irregularities, even if corrugated cardboard sheets or the like are stacked, they will not fall down. Moreover, since the traveling conveyor and the payout conveyor intersect with each other and can be independently driven without interference, the direction can be changed to the right angle direction. Therefore, a corrugated cardboard sheet or the like can be transported and turned without laying a veneer plate or the like underneath.

EXAMPLES Next, examples of the present invention will be described. Figure 5
Shows a transportation lane L arranged between one corrugator Cg and 16 box making machines F1 ... F16. Corrugator Cg
Is an apparatus for manufacturing corrugated cardboard sheets by pasting corrugated cardboard base paper and cutting it into an arbitrary shape, and the manufactured corrugated cardboard sheets are sent from the stacker St one lot at a time. A box making machine is an apparatus for manufacturing a cardboard box, and is a combination of a printing machine and a paper processing machine. The transport lane L is a stacker
A receive unit Re for receiving the corrugated board sheet S sent from St, a bidirectional conveyor unit U3 for turning the corrugated board sheet S at a right angle, and a one-way conveyor unit U1 for sending the corrugated board sheet S in one direction are additionally provided. , And each of the stock lanes f1 ... f16 is made up of a bidirectional conveyor unit U2.
The bidirectional conveyor unit U2 is a conveyor unit for changing the direction of the corrugated board sheet S sent in the a direction on the transport line L to a right angle and delivering it in the b direction. The transport line L may have an L shape as shown in FIG. 5, a U shape, or any other shape.

In the transport lane L as described above, the belt conveyor device of the present invention is used for the bidirectional conveyor units U2 and U3 whose transport direction must be changed to a right angle.

In FIG. 1, U is a belt conveyor device according to an embodiment of the present invention, which is capable of changing the conveying direction.
It is composed of a traveling conveyor unit A that feeds in the same direction a as the transport line L and a payout conveyor unit B that feeds in a direction b orthogonal to the direction a.

The traveling conveyor unit A comprises a traveling conveyor 1 and a traveling conveyor 2 which are short and wide, and the pitch between two rollers (head side and tail side) is shorter than the width of the rollers, that is, the width of the belt. is there. The term “short length” means that this pitch is short, but when the conveyors 1 and 2 are compared, the conveyor 1 is slightly longer. The conveyors 1 are arranged at both ends of the conveyor device U, and the conveyors 2 are arranged between them. This arrangement is in the transport direction a
Are arranged in series along with each other, and an interval for installing a payout conveyor 3 described later is provided between the conveyors 1 and 2.
The conveyors 1 and 2 are arranged in two rows. Each of the conveyors 1 and 2 is connected to the motor M1 via the chain 4 and the shaft 5, and is driven in the direction of arrow a or in the opposite direction. (Fig. 2 (B)
reference).

The payout conveyor unit B is composed of a plurality of payout conveyors 3 each having a long and narrow width, and the payout conveyor units B are arranged in parallel between the traveling conveyors 1 and 2. The pitch of the payout conveyor 3 is long and longer than the width of the traveling conveyor unit A, and the width is narrow and band-shaped. The payout conveyor 3 is connected to a motor M2 via a chain 4 and a shaft 6, and is driven in the direction of arrow b or in the opposite direction. (Fig. 3
(See (B)). The drive direction indicated by the arrow b is a direction orthogonal to the drive direction of the conveyors 1 and 2.

With the above arrangement, the traveling conveyors 1 and 2 and the payout conveyor 3 are arranged so as to intersect with each other and can be driven without interference. Therefore, with the above layout, the direction can be changed by one belt conveyor device, and the conventional belt conveyor system requires the turntable at the contact point of the two belt conveyors, but it is not necessary to provide this. The effect will be produced.

The frame of each of the conveyors 3 is mounted to be movable up and down by the up base units 10 and 11. The up base unit referred to in the present specification is a type of lifting device as claimed in the claims, and as shown in FIG. 4, a box-shaped upper case 12 and a lower case 13 are slidably fitted vertically. In addition, the air hose 14 is inserted inside, and when high-pressure air is injected into and discharged from the air hose 14, the air hose 14 expands and contracts, and the upper case 12 is approximately 20-40.
It can be raised and lowered with a stroke of mm. This up-base unit has a large pressure receiving area, and thus has an advantage that a large pushing force can be easily obtained. Further, the conveyor 3 may be lifted and lowered by one up base unit, or a plurality of conveyors may be stacked to increase the lifting amount.

By driving the up base units 10 and 11 shown in FIG. 3A, the conveyor 3 can be moved up and down. Then, at the position where the conveyor 3 is raised, the sheet S can be moved in the arrow b direction without interfering with the adjacent conveyors 1 and 2. Further, at the position where the conveyor 3 is lowered, it does not interfere with the article being conveyed when the adjacent sets of conveyors 1 and 2 are driven.

Next, the transport operation of this embodiment will be described.

As shown in FIG. 2A, the corrugated board sheet S
Are fed in the direction of arrow a by the conveyors 1 and 2, and when the conveyors 1 and 2 are stopped, the conveyor 3 rises as shown in FIG. 2 (B) and starts traveling in the direction of arrow b (see FIG. 3 (A)). ). The corrugated board sheet S is paid out by the traveling of the conveyor 3. When the sheet S completes the payout, the conveyor 3 stops and moves down to the lowered position. As described above, the sheet S is changed in the conveying direction at a right angle, but during this period, the sheet S is placed on the flat belt and thus does not fall down. Therefore, it is not necessary to lay a veneer plate under the sheet S.
