Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated work transfer device suitable for stacking plate-like works such as a body blank, which is a can body material, and transferring them as an integrated work.

[0002]

2. Description of the Related Art The applicant has previously filed Japanese Patent Application No. 3-343174.
For example, a slitter for cutting a large-sized thin plate such as a tin plate or a tin-free steel plate into a body blank (hereinafter referred to as "blank") for forming a can body of a predetermined size, and a cylindrical blank of the blank. We have proposed a transport device for transporting the blank between the body maker and the body maker. The apparatus comprises a blank charging means for stacking a predetermined number of blanks formed by the slitter and charging them as an integrated blank, a plurality of buckets on which the integrated blanks charged by the blank charging means can be mounted, and those buckets. A forward conveyor for moving the stacking blank in the conveying direction, a blanking dispenser for dispensing the stacking blank from the bucket at the end of the forwarder conveyor, and a blank dispensing means for supplying the stacking blank to the body maker, and the blank dispensing device for dispensing the stacking blank. And a return conveyor that moves the bucket to the starting end of the forward conveyor. That is, the forward path conveyor continuously moves the plurality of buckets loaded with the integrated blanks loaded by the blank loading means from the starting end portion to the terminating end portion in the blank conveying direction.

As a result, since the stacking blank being transported is mounted on the bucket having a side wall in the transporting direction, the stacking state is maintained and the plurality of blanks are prevented from being displaced from each other to collapse the load. High-speed conveyance of blanks becomes possible.

By the way, in this type of transfer device,
Generally, the processing speed of the slitter is higher than the processing speed of the body maker, and in order to balance the processing speed of the slitter and the processing speed of the body maker to improve the operating efficiency of both, It is desirable to carry blanks from a single slitter to multiple bodymakers. Therefore, for example, a first forward path conveyor that conveys buckets loaded with integrated blanks that have been loaded from the slitter via a blank loading means, and a cross section orthogonal to both sides of the forward path conveyor from the end portion of the first forward path conveyor. Transporting means for alternately allocating and transporting a plurality of buckets on which integrated blanks are mounted in the direction of moving, and moving the respective buckets transported from both ends of the transporting means to the first body maker and the second body maker. It is possible to convey the integrated blank from the single slitter to the first body maker and the second body maker by providing the second outward conveyor and the third outward conveyor.

However, when the buckets are distributed to both sides of the forward conveyor by the transfer device in this way, in general, different buckets are transferred to both sides of the forward conveyor so as to move away from each other. A device is required, and even if the buckets are distributed by the same transfer device, the structure of the transfer device becomes large and complicated.

[0006]

DISCLOSURE OF THE INVENTION The present invention eliminates such inconvenience, and can easily convey an integrated work from a single work insertion means to a plurality of work ejection means, and has a structure. It is an object of the present invention to provide a simple conveying device for accumulated works.

[0007]

In order to achieve the above object, the present invention is provided with an integrated work holding member for holding an integrated work formed by stacking a predetermined number of plate-like works, and the integrated work can be mounted freely. Which is a bucket, a work throwing means for throwing a work into the bucket, a work paying means for paying out a work from the bucket, and a work throwing means for throwing the work from the work throwing means toward the work paying means. A conveyor that supports and moves a plurality of buckets loaded with accumulated work, and a bucket on which the accumulated work is loaded is selected from one of the conveyors in the direction orthogonal to the conveying direction of the conveyor. Transfer means for discharging and transferring the bucket, and receiving the bucket transferred by the transfer means and supporting the bucket to move the bucket. Characterized in that it comprises the other conveyor, from the mobile bucket at the end of the accumulating work paying out another of the other conveyor and the workpiece dispensing unit.

[0008]

In the case of carrying an integrated work formed by stacking a predetermined number of plate-like works by the carrying device of the present invention,
First, in the bucket supported at the starting end of the conveyor,
The integrated work input from the work input means is stored. The bucket holds the accumulated work by the accumulated work holding member. As a result, it is possible to perform high-speed conveyance without causing the work load to collapse when the bucket moves.

Next, the bucket loaded with the accumulated work is moved to the end portion of the conveyor, where the accumulated work is discharged by the work discharging means.

On the other hand, one of the buckets moved by the conveyor is selectively transferred to another conveyor by the transfer means. The transfer means only needs to selectively pay out the buckets on which the accumulated works are mounted in one of the directions orthogonal to the transport direction of the conveyor in the middle of the conveyor. It is sufficient that the bucket is transferred only in one direction without providing the means for distributing.

Next, in the bucket in which the accumulated work moved to the terminal end portion thereof by another conveyor is mounted, the accumulated work is discharged there by another work discharging means.

Since the bucket 5 supports the blank W discharged from the slitter A from the three sides by the side walls 16, 17, and 18, the predetermined number of stacking blanks W while preventing the collapse of the load.
Can be installed.

As shown in FIG. 2, the first outward conveyor 1 is driven in the moving direction of the bucket 5 by an endless strip 19 having a plurality of rotatable rollers (not shown) on the upper surface thereof. The bucket 5 is the first forward conveyor 1
Above, it is supported by the rollers of the endless strip 19 and is in a so-called free-flow conveyor state. As a result, when the first outward conveyor 1 is driven, the bucket 5 normally moves, but the bucket 5 can be appropriately stopped even when the first outward conveyor 1 is driven.

The first return conveyor 2 is shown in FIG.
As shown in FIG. 3, the endless strip 20 is provided with the same configuration as the first outward conveyor 1, and the bucket 5 is supported by the rollers of the endless strip 20 to form a so-called free flow conveyor.

The first bucket delivery means 11 is provided with an elevating and lowering table 21 for receiving and mounting the bucket 5 from the terminal end portion of the first outward conveyor 1, and the first elevating table 21 is provided with the first and second elevating tables 21. The bucket 5 on the forward conveyor 1 is transferred. Then, when the lifting table 21 is lowered, the bucket 5 on the lifting table 21 is transferred to the starting end portion of the first backward path conveyor 2.

The first blank payout means 9 is provided at the end of the first outward conveyor 1. As a result, the blank W in the bucket 5 placed on the elevating table 21 is taken out of the bucket 5 by the blank gripping means 22 provided in the blank dispensing means 9. Then, the first blank payout means 9
The blank W dispensed by is supplied to the first body maker B.

Further, the second bucket delivery means 12 is provided so as to be connected to the end of the first return conveyor 2. The second bucket delivery means 12 has the same structure as the first bucket delivery means 11 and is provided with an elevating table 23 that can be raised and lowered.
The bucket 5 on the first return conveyor 2 is transferred to No. 3.
Then, when the lifting table 23 rises, the bucket 5 on the lifting table 23 is transferred to the starting end portion of the first outward conveyor 1.

The second forward conveyor 3 is shown in FIG.
As shown in FIG. 3, the first outward conveyor 1 is extended from a substantially central position in parallel with the first outward conveyor 1 toward a blank W dispensing position by the second blank dispensing means 10. There is. The second outward conveyor 3 is
As shown in FIG. 2, an endless strip 24 provided with a plurality of rotatable rollers (not shown) on its upper surface side is driven in the moving direction of the bucket 5, and the bucket 5 is placed on the second forward path conveyor 3. In this case, the endless strip 24 is supported by the rollers to be in a so-called free-flow conveyor state.

A forward path transfer means 6 is connected to a starting end portion of the second outward path conveyor 3 and extends in a direction orthogonal to one direction from a substantially central position of the first outward path conveyor 1. The forward path transfer means 6 selectively transfers the bucket 5 moving along the first forward path conveyor 1 to the second forward path conveyor 3. The transfer direction of the bucket 5 by the outward transfer means 6 is toward one side orthogonal to the moving direction of the bucket 5 of the first outward conveyor 1. As a result, when the forward transfer means 6 transfers the bucket 5 from the first forward conveyor 1 to the second forward conveyor 3,
It becomes easy to prevent the collapse of the load of the stacking blank W mounted on the bucket 5. That is, in the present embodiment, the stacking blank W is mounted on the bucket 5 in a state in which the collapse of the load is prevented by the side walls 16, 17, 18, but the stacking means 8 stacks the stacking blank W from the side of the bucket 5. In order to insert the blank W, the side of the bucket 5 facing the side wall 18 is open. Therefore, the bucket 5 moving on the first outward conveyor 1 is prevented from collapsing in the traveling direction by the side walls 16 and 17, but the bucket 5 is moved in the direction orthogonal to the first outward conveyor 1. When the bucket 5 is moved, the stacking blank W mounted on the bucket 5 may collapse from the open portion of the bucket 5 on the side facing the side wall 18. Therefore, the forward transfer means 6 is connected to the first forward conveyor 1
By extending only in a direction orthogonal to one side, for example, a load collapse preventing means such as a locking plate (not shown) for locking one side of the stacking blank W exposed from the open side of the bucket 5 Is provided in the outward transfer means 6, and the bucket 5 may be transferred by moving the load collapse preventing means in the transfer direction of the bucket 5. As described above, since the outward transfer means 6 transfers the bucket 5 only in one direction, the structure of the collapse prevention means for the stacked blank W from the open side of the bucket 5 is simplified. At the same time, the structure of the device can be simplified as compared with the conventional case in which buckets are alternately distributed in both lateral directions orthogonal to the outward conveyor. Even when the forward path transfer means 6 moves a bucket having a structure other than the bucket 5 in the present embodiment by the first forward path conveyor 1, the bucket is conveyed in the transport direction of the first forward path conveyor 1. Since it need only be transferred in one direction orthogonal to, the control and the like can be facilitated.

The second return conveyor 4 is shown in FIG.
As shown in FIG. 3, the endless strip 25 is provided by the same configuration as the second outward conveyor 3, and the bucket 5 is supported by the rollers of the endless strip 25, so that the so-called free flow conveyor is formed.

The third bucket delivery means 13 is provided with an elevating and lowering table 26 for receiving and mounting the bucket 5 from the terminal end portion of the second outward path conveyor 3, and the second elevating and lowering table 26 is provided with the second elevating table 26. The bucket 5 on the forward path conveyor 3 is transferred. Then, when the lifting table 26 descends, the bucket 5 on the lifting table 26 is transferred to the starting end portion of the second return conveyor 4.

The second blank payout means 10 is provided at the end of the second outward conveyor 3. As a result, the blank W in the bucket 5 placed on the elevating table 26 is removed from the blank dispensing means 10.
It is taken out of the bucket 5 by the blank gripping means 27 provided in. The blank W dispensed by the second blank dispensing means 10 is supplied to the second body maker C.

Further, a return path transfer means 7 for transferring the bucket 5 from the second return path conveyor 4 to a substantially central position of the first return path conveyor 2 is connected to a terminal end portion of the second return path conveyor 4. ing. The bucket 5 transferred to the first return conveyor 2 by the return transfer means 7 merges with another bucket 5 moving on the first return conveyor 2 to the end portion of the first return conveyor 2. Will be moved.

The transporting apparatus of the present invention is configured as described above, and by the first forward path conveyor 1 and the second forward path conveyor 3, the single slitter A is integrated into a plurality of bodymakers B and C. It is possible to easily carry the blank W, and, between the second forward path conveyor 3 and the first forward path conveyor 1, the forward path transfer means 6 causes the bucket 5 to move to the first forward path conveyor 1. Since the bucket 5 is moved so as to be directed to one side orthogonal to the moving direction of the bucket 5, the structure of the outward transfer means 6 can be simplified.

Further, according to the carrying apparatus of the present invention, for example, as shown in FIG. 4, a third forward path conveyor 28 and a second forward path conveyor 28, which have the same structure as the second forward path conveyor 3 and the second backward path conveyor 4, It is possible to add a third return conveyor (not shown). And the third outward conveyor 2
A third body maker D can be provided at the terminal end of 8 through a third blank payout means 29 having the same structure as the second blank payout means 10. At this time, the forward transfer means 6 may transfer the bucket 5 on the first forward conveyor 1 so as to move toward the one side orthogonal to the moving direction thereof, and therefore, as shown in FIG. Only by extending the transfer distance by the outward transfer means 6 and providing the transfer means 30 on the second outward conveyor 3, the bucket 5 can be easily provided to each of the second outward conveyor 3 and the third outward conveyor 28. Can be transferred. Incidentally, the return path transfer means 7 is also the same as the forward path transfer means 6 in the bucket 5.
All you have to do is extend the transfer distance.

[0034]

As is apparent from the above, according to the present invention, an integrated work formed by accumulating a predetermined number of plate-like works is placed in a bucket provided with an integrated work holding member, and the bucket is driven. Since it is supported on a conveyor and transported,
When the bucket moves, it is possible to prevent the work from collapsing and to carry the work at high speed.

Further, according to the present invention, the transfer means selectively ejects the buckets on which the accumulated work is mounted from the conveyor in one of the directions orthogonal to the conveying direction of the conveyor in the middle of the conveyor. Since it is transferred to another conveyor, it is possible to easily carry the integrated work from the single work input means to the plurality of work delivery means.

Further, according to the present invention, since the transfer direction of the bucket by the transfer means is one direction, for example, the bucket can be transferred to another conveyor without being alternately distributed in a direction orthogonal to both sides of the conveyor. Since the bucket can be transferred, the structure of the transfer means can be simplified.
