It is known that the sheets are sequentially conveyed (for example, see Patent Document 1).

In recent years, from the viewpoint of environment and economy, weight reduction of vehicles, ships, aircrafts, etc. has been demanded.
In the field of metalworking, as a part of that, it is considered to replace the iron plates, steel plates and the like used as raw materials for these products with lighter aluminum plates, FRP plates and the like.
However, since aluminum plates, FRP plates and the like are so-called non-magnetic materials that do not exhibit magnetism, belt conveyors and robots using conventional magnets including the pillar conveyor described in Patent Document 1 described above are used for carrying them. There is a problem that you can not.

On the other hand, in a transfer device having a belt conveyor, an urging means, and a moving means, the moving means synchronizes the urging means with the belt conveyor while the urging means urges the object to be conveyed to the conveyor surface. There is known a method of causing it to advance in the transport direction (for example, refer to Patent Document 2).

(First embodiment)
FIG. 1 is a side view schematically showing a first embodiment of a non-magnetic blank carrying device according to the present invention.
The support bar 50 and the narrow conveyor 10a are not shown.
As shown in FIG. 1, the non-magnetic blank carrying device 100 according to the first embodiment is arranged with an endless carrier conveyor 10 on which the non-magnetic blank 1 is placed, and a predetermined distance above the carrier conveyor 10. The plurality of suction units 20 that are movable in the horizontal direction, the support conveyor 30 to which the plurality of suction units 20 are attached, the linear motion device 40 for moving the support conveyor 30 up and down, and the non-magnetic blank 1 And a support bar (not shown) for urging the above.

In the non-magnetic blank carrying device 100, as will be described later, the non-magnetic blank is carried in a state where its upper surface is sucked by the suction unit 20 and its lower surface is supported by the carrying conveyor 10. Thereby, it is possible to prevent the non-magnetic blank 1 from being scratched and deformed, and it is possible to reliably transport the non-magnetic blank 1.

The conveyor 10 comprises a plurality of narrow conveyors 10a. Each narrow conveyors 10a are all made the same structure.
FIG. 2 is a partial front view of the non-magnetic blank carrying device of FIG.
As shown in FIG. 2, the narrow conveyor 10a is stretched over the narrow drive pulley 11, the narrow driven pulley 12, the narrow drive pulley 11 and the narrow driven pulley 12, and is narrower than the non-magnetic blank. The narrow belt 13 and the driving device 14 for sliding the narrow conveyor 10a in the Z-axis direction. The narrow drive pulley 11 and the narrow driven pulley 12 are supported by a frame (not shown).
That is, the transport conveyor 10 is composed of a plurality of narrow width conveyors 10a arranged so as to be parallel to each other, and each narrow width conveyor 10a is independently or synchronously driven by the drive device 14 in the Z-axis direction. It is possible to slide to.

When the non-magnetic blank 1 is placed on the upper surface of the transfer conveyor 10, the non-magnetic blank 1 is supported by the plurality of narrow width conveyors 10a. At this time, each narrow conveyor 10a can be slid in the Z-axis direction according to the shape of the non-magnetic blank 1 and the size in the Z-axis direction, and the position can be adjusted so as to support the non-magnetic blank 1 in a well-balanced manner. preferable.
When the narrow drive pulleys 11 of the narrow conveyors 10a are driven in this state, the narrow conveyors 10a simultaneously rotate in the same direction. The narrow drive pulleys 11 of the narrow conveyors 10a may be connected to each other for synchronization. The same applies to the driven pulley 12. As a result, the placed non-magnetic blank 1 can be conveyed in the X-axis direction (from left to right in FIG. 1) while being supported by the plurality of narrow conveyors 10a.

Returning to FIG. 1, in the non-magnetic blank carrying device 100, two suction magnets are provided at a certain distance above each of them so as to correspond to the two non-magnetic blanks 1 placed on the carrying conveyor 10. The part 20 is arranged.

Hereinafter, in the present specification, for convenience, the upstream adsorption portion 20 in the transport direction (X-axis direction) is referred to as an “upstream adsorption portion 20a”, and the downstream adsorption portion 20 is referred to as a “downstream adsorption portion 20b”. ". The upstream suction section 20a and the downstream suction section 20b are arranged at a constant interval.
In addition, the position on the transfer conveyor 10 before the transfer of the non-magnetic blank 1 transferred in the X-axis direction by the transfer conveyor 10 and the upstream suction unit 20a is the first position P1, and the transfer conveyor 10 after the fixed distance has been transferred. The upper position is the second position P2. That is, the first position P1 is on the transport conveyor 10 immediately below the upstream suction unit 20a before transportation, and the second position P2 is on the transport conveyor 10 immediately below the upstream suction unit 20a after transportation. The distance between the upstream suction portion 20a and the downstream suction portion 20b corresponds to the distance between the first position P1 and the second position P2.
By the way, as will be described later, the position of the non-magnetic blank 1 that is conveyed in the X-axis direction by the conveyor 10 and the downstream adsorption unit 20b on the conveyor 10 before the conveyance is the second position P2, and the conveyor after the conveyance is the second position P2. The position on 10 is the third position (not shown). That is, the second position P2 is on the transport conveyor 10 immediately below the downstream suction unit 20b before transportation, and the third position (not shown) is on the transport conveyor 10 immediately below the downstream suction unit 20b after transportation.

The upstream side suction portion 20a and the downstream side suction portion 20b both have the same structure. Specifically, each of the upstream suction section 20a and the downstream suction section 20b has a base body 21 and a plurality of suction cups 22 attached to the base body 21 and extending downward from the base body 21.
Here, the inside of the suction cup 22 is hollow, and the inside is sucked by a suction source (not shown). Therefore, the non-magnetic blank is attracted to the suction cup 22 by bringing the non-magnetic blank into contact with the lower surface of the suction cup 22 and sucking the inside of the suction cup 22 by the suction source. The suction source for sucking the inside of the suction cup 22 of the upstream suction section 20a and the suction source for sucking the inside of the suction cup 22 of the downstream suction section 20b may be the same or different. It may be.

Each of the upstream suction portion 20a and the downstream suction portion 20b has a base body 21 attached to the support rod 25 via a connecting portion 25a that is vertically provided on the support rod 25. That is, the base portion 21 of the upstream suction portion 20a is hung down to the upstream end portion of the support rod 25 via the connecting portion 25a, and the base portion 21 of the downstream suction portion 20b is connected via the connecting portion 25a. The support rod 25 is vertically provided at an end portion on the downstream side.

Here, the support rod 25 has a quadrangular prism shape, and has a structure that extends horizontally in the X-axis direction. Therefore, the upstream suction unit 20a and the downstream suction unit 20b are arranged at intervals along the X-axis direction and at the same height from the narrow conveyor 10a.
Further, the support rod 25 is attached to a support conveyor 30 described later at a substantially central portion thereof.
Therefore, in the non-magnetic blank carrying device 100, the upstream suction unit 20 a and the downstream suction unit 20 b are attached to the support conveyor 30 via the support rod 25.

The support conveyor 30 includes a plate-shaped main body portion 35, a drive pulley 31 and a driven pulley 32 that are vertically provided on both ends of the main body portion 35, and a support belt 33 that is stretched around the drive pulley 31 and the driven pulley 32. Consists of.
The support belt 33 is provided with a fixing portion 33a.
The substantially central portion of the support rod 25 described above is attached and fixed to the fixing portion 33a.

In the support conveyor 30, when the drive pulley 31 is driven, together with the support belt 33, the fixed portion 33a, the support rod 25 attached and fixed to the fixed portion 33a, and the upstream suction portion attached to the support rod 25. 20a and the downstream suction portion 20b are integrally movable in the X-axis direction.
Therefore, the two non-magnetic blanks 1 are conveyed in the X-axis direction (from left to right in FIG. 1) in a state where they are adsorbed to the upstream adsorption portion 20a or the downstream adsorption portion 20b, respectively.

In the non-magnetic blank device 100, the lower surface of the non-magnetic blank 1 is supported by the conveyor 10 as described above, and at the same time, the upper surface of the non-magnetic blank 1 is adsorbed by the adsorption unit 20, The transport conveyor 10 and the support conveyor 30 are synchronized and moved in the X-axis direction at the same speed.

In the non-magnetic blank carrying device 100, a linear motion device 40 for moving the support conveyor 30 up and down is attached to a substantially central portion of the main body 35 of the support conveyor 30.
Therefore, in the non-magnetic blank carrying device 100, by driving the linear motion device 40, not only the support conveyor 30 but also the support rod 25 attached to the support conveyor 30 and the upstream attached to the support rod 25. The side suction portion 20a and the downstream suction portion 20b are integrally moved up and down.
As a result, in the non-magnetic blank carrying device 100, it is possible to simultaneously move the upstream suction unit 20a and the downstream suction unit 20b up and down.

The linear motion device 40 employs a servo motor drive.
Accordingly, in the non-magnetic blank carrying device 100, it is possible to control the distance by which the upstream suction unit 20a and the downstream suction unit 20b are moved up and down. That is, it is possible to accurately control the positions of the upstream suction unit 20a and the downstream suction unit 20b when moving up and down.

From these things, in the non-magnetic blank carrying device 100, the suction cup 22 of the upstream suction unit 20a and the suction cup 22 of the downstream suction unit 20b are set so as not to bias the two non-magnetic blanks 1 as much as possible. It is possible to simultaneously descend with high accuracy to a position in contact with the upper surface of the corresponding non-magnetic blank 1. This can reduce the impact on the non-magnetic blank 1 when the suction cup 22 is brought into contact with the non-magnetic blank 1.

Returning to FIG. 2, in the non-magnetic blank carrying device 100, the linear motion device 40 is supported by the frame 9.
The support conveyor 30 is attached to the frame 9 via the LM guide 5 including the LM rail 5a and the LM block 5b. That is, the support conveyor 30 is attached such that the LM block 5a attached to the main body portion 35 is slidable along the LM rail 5b provided on the frame 9 and extending in the Y-axis direction. As a result, the support conveyor 30 is guided in the Y-axis direction.

In the non-magnetic blank carrying device 100, a support bar 50 extending in the Y-axis direction is arranged between adjacent narrow width conveyors 10a.
Further, the support bar 50 has a contact rubber body 51 attached to the upper end thereof, and an elevating device (not shown) attached to the lower side thereof. For this reason, the support bar 50 can be moved up and down by the lifting device, and if the support bar 50 is moved up, the contact rubber body 51 of the support bar 50 contacts the lower surface of the non-magnetic blank 1. They are brought into contact with each other and further urged upward.

Accordingly, in the non-magnetic blank carrying device 100, the support bar 50 biases the lower surface of the non-magnetic blank 1 upward, so that the non-magnetic blank 1 is bent downward in the gap between the narrow conveyors 10a. It is possible to solve the problem.
As a result, when the suction cup 22 of the suction unit 20 is brought into contact with the upper surface of the non-magnetic blank 1, the support bar 50 eliminates the bending of the non-magnetic blank 1, so that the suction unit 20 evenly distributes the non-magnetic blank 1. In addition, it is possible to surely adsorb.

Next, a method of carrying the non-magnetic blank 1 using the non-magnetic blank carrying device 100 according to the first embodiment will be described.
FIG. 3 is a flow chart showing a method of conveying a non-magnetic blank according to the first embodiment.
As shown in FIG. 3, the method of transporting the non-magnetic blank 1 according to the first embodiment includes a belt position adjusting step S1, an arranging step S2, a lower surface contacting step S3, an upper surface contacting step S4, and a suction step. S5, a downward deviation step S6, a conveyance step S7, a stop step S8, an upward deviation step S9, and a repatriation step S10 are provided.
In the method of transporting a non-magnetic blank, the above-described non-magnetic blank transport device 100 is used and these steps are sequentially performed.

4A to 4D are explanatory views for explaining the belt position adjusting step, the arranging step, the lower surface abutting step, and the upper surface abutting step in the non-magnetic blank carrying method according to the first embodiment. is there.
As shown in FIGS. 4A and 4B, the belt position adjusting step S1 is a step of sliding the narrow conveyor 10a in the Z-axis direction so that at least both sides of the non-magnetic blank 1 can be supported. is there.
At this time, in order to support the non-magnetic blank 1 in a well-balanced manner, the position of the narrow conveyor 10a is adjusted so that the non-magnetic blank 1 is placed at the same distance H in the Z-axis direction on both sides from the XZ plane including the center of gravity. Preferably.

As shown in (b) and (c) of FIG. 4, the arranging step S2 is a step of arranging the non-magnetic blank 1 at the first position P1 (see FIG. 1) on the narrow conveyor 10a. The method of such arrangement is not particularly limited. For example, it may be placed at the first position P1 by being transported by the transport conveyor 10, may be placed at the first position P1 by being transported by another conveyor, or may be placed at the first position P1 by a robot or the like.

As shown in (c) and (d) of FIG. 4, the lower surface abutting step S3 is a step of raising the support bar 50 between the narrow width conveyors 10a and abutting it on the lower surface of the non-magnetic blank 1, The upper surface contacting step S4 is a step in which the linear motion device 40 lowers the support conveyor 30 to bring the suction cup 22 of the suction unit 20 into contact with the upper surface of the non-magnetic blank 1. In the upper surface contacting step S4, the suction cups 22 of the upstream suction unit 20a and the downstream suction unit 20b are simultaneously brought into contact with the upper surfaces of the corresponding non-magnetic blanks 1 by lowering the support conveyor 30. (See FIG. 5A).
As a result, the non-magnetic blank 1 is sandwiched between the suction unit 20 and the narrow conveyor 10a. In the gap between the narrow conveyors 10a, the non-magnetic blank 1 is sandwiched between the suction unit 20 and the support bar 50 without being bent downward by gravity.

The suction step S5 is a step of sucking the upper surface of the non-magnetic blank 1 by the suction unit 20 via the suction cup 22.
As described above, by performing the suction step S5 while sandwiching the non-magnetic blank 1, the non-magnetic blank 1 can be more effectively attracted to the adsorption unit 20.
By performing the suction step S5, the downward biasing force of the suction portion 20 is not applied to the non-magnetic blank 1, and conversely, the upward suction force is exerted.

Here, the lower surface contacting step S3 and the upper surface contacting step S4 are performed substantially at the same time. Thereby, damage to the non-magnetic blank 1 at the time of contact can be further reduced.
Further, in addition to this, it is preferable that the suction step S5 is also performed substantially simultaneously. In this case, the time required for each step is shortened, so that the yield can be improved.
When the lower surface contacting step S3, the upper surface contacting step S4, and the suctioning step S5 are not performed at the same time, it is preferable to perform them in this order in succession in the shortest possible time.

The downward separation step S6 is a step in which the support bar 50 is moved down and separated from the nonmagnetic blank 1 after the adsorption section 20 has sufficiently adsorbed the nonmagnetic blank 1. Accordingly, it is possible to prevent the support bar 50 from obstructing the conveyance of the non-magnetic blank 1.
By performing the downward separation step S6, the upper surface of the non-magnetic blank 1 is adsorbed by the adsorption portion 20, and both sides of the lower surface thereof are supported by the narrow conveyor 10a.

5A to 5D are explanatory views for explaining the carrying step, the stopping step, the upward deviation step, and the returning step in the method for carrying a nonmagnetic blank according to the first embodiment.
As shown in (a) and (b) of FIG. 5, in the carrying step S7, the upstream adsorption portion 20a sucks the upper surface of the upstream non-magnetic blank 1 and the downstream surface of the downstream non-magnetic blank 1 downstream. The non-magnetic blank 1 on the upstream side is sucked by the side suction portion 20b, and the non-magnetic blanks 1 on both sides are supported by the conveyor 10 (narrow conveyor 10a) on the lower surfaces of the non-magnetic blanks 1 from the first position P1 to the second position P1. This is a step of transporting the nonmagnetic blank 1 on the downstream side to the second position P2 from the second position P2 to the third position P3.

At this time, the upstream suction unit 20a and the downstream suction unit 20b are synchronized with the transport conveyor 10 to move in the X-axis direction. That is, the traveling timing and traveling speed of the support belt 33 of the support conveyor 30 and the narrow belt 13 of the transport conveyor 10 are synchronized.
This makes it possible to prevent the non-magnetic blank 1 from being scratched and deformed, and to reliably transport the non-magnetic blank 1.
A new non-magnetic blank is arranged at the first position P1 at the timing when the carrying step S7 is performed.

Stop step S8 is a step of stopping suction by the suction source. As a result, the non-magnetic blank 1 is released from the state in which the non-magnetic blank 1 is attracted to the upstream adsorption portion 20a and the downstream adsorption portion 20b.
In the stop step S8, not only the suction by the suction source is stopped, but also air may be positively sent into the suction cup 22 in order to return the inside of the suction cup 22 to the normal pressure.

As shown in (b) and (c) of FIG. 5, in the upward deviation step S9, the linear motion device 40 raises the support conveyor 30 to raise the upstream suction unit 20a and the downstream suction unit 20b, This is a step of separating these suction cups 22 from the non-magnetic blank 1. In the upward deviation step S9, the suction cups 22 of the upstream suction section 20a and the downstream suction section 20b are simultaneously separated from the upper surface of the corresponding non-magnetic blank 1 by raising the support conveyor 30.

As shown in (c) and (d) of FIG. 5, in the repatriation step S10, the support conveyor 30 repatriates the upstream adsorption unit 20a and the downstream adsorption unit 20b in the X-axis direction opposite to the transport direction. Is.
As a result, the upstream suction unit 20a is returned from above the second position P2 to above the first position P1, and the downstream suction unit 20b is sent from above the third position P3 to above the second position P2. Will be.
Note that the non-magnetic blank arranged at the third position P3 is taken out by another conveyer, robot, or the like at the timing when the repatriation step S10 is performed.

In the method of transporting the non-magnetic blank, the non-magnetic blank 1 can be continuously transported by repeating the above steps.

(Second embodiment)
FIG. 6 is a side view showing the outline of the second embodiment of the non-magnetic blank carrying device according to the present invention.
As shown in FIG. 6, the non-magnetic blank carrying device 101 according to the second embodiment is arranged above the carrying conveyor 10 and an endless carrying conveyor 10 on which the non-magnetic blank 1 is placed, with a certain distance.
