Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a supply device for materials for vibration damping parts. [Prior Art] Recently, in order to ensure quietness in washing machines and the like, the bodies of washing machines and the like are often manufactured using so-called vibration-damping steel plates. Many vibration-damping steel plates have a triple-layer structure, which is made by adhering two steel plates with a plastic material interposed between them. Such damping steel plates have good processing efficiency, but because plastic is interposed between the steel plates, it is extremely difficult to manufacture vibration damping parts such as the body of the washing machine by contacting the steel plates.
Also, the cost is high. Furthermore, the vibration damping steel plate has the disadvantage that it is difficult to improve quietness due to its elliptical structure. Therefore, in order to solve the above-mentioned difficulties, it is considered that instead of interposing a plastic material between the two pressed materials, an air layer is formed to prevent the vibration-damping steel plate from intervening. By the way, when manufacturing vibration damping parts from such damping steel plates, two steel plates are separately fed into a press and formed, and then the formed steel plates are shaped so that an air space is formed between the steel plates. One idea is to join them together, but in order to further improve processing efficiency, an operator forms a damping steel plate from one material Wt and the other material W2 immediately before the press 65, as shown in FIG. It is conceivable to manufacture vibration damping parts by supplying the damping steel plate to the brace 65 and shaping it at the same time. Here, in FIG. 6, 85 is a part where a press material supply source such as an uncoiler/destack feed device is installed, and 80 is a part where the material is transferred to the press 65 via a conveyance path 81 such as a chain conveyor. This is a material supply device. [Problem to be solved by the invention] By the way, when manufacturing vibration damping parts as described above,
The worker must lift the other material W2 above the one material Wl on the transport path 81, adjust its posture, and then place it on the one material Wl. This places an excessive burden on the worker and makes the work difficult. This becomes complicated and makes it difficult to achieve high-speed press operations. In addition, if the materials are particularly large, one worker may not be able to stack the materials alone.
This is a problem in this day and age, where there is a strong demand for labor savings, as there is a risk that two workers will have to work together and the work will have to be carried out in tandem. The purpose of the present invention is to produce a vibration damping component that is easy to weld, is quiet, and is inexpensive. An object of the present invention is to provide a supply device for material for vibration parts.

[Means for Solving the Problems 1] The present invention includes a one-way conveyance means for supplying one-sided material to a press from one part, and a conveyance path that forms the one-way conveyance means from the other part and intersects with the conveyance path in the middle of the conveyance path. the other conveying means for feeding the other material from the direction in which the two conveying means intersect; and a delivery means for picking up the other material from the other conveying means and placing it on the one material supported by the one conveying means at the intersection of the two conveying means; and is characterized in that it is configured to be able to simultaneously convey two sheets of material stacked on the downstream side of the intersection portion of the one-way conveyance means. [Function] In the present invention, one material is transported from one part to the press by one transport means, and the other material is transported from the other part to the intersection with the one transport means by the other transport means. At the crossing point, the other member is placed on one of the materials by the transfer means, and the one conveying means acts so as to simultaneously convey the two stacked materials downstream from the crossing point. Therefore, two sheets of one material and the other material can be stacked and fed to the press, making it possible to manufacture vibration-damping parts that are easy to weld, are highly quiet, and are inexpensive. [Implementation-1] An embodiment of the present invention will be explained based on the drawings. In order to manufacture vibration damping parts that are easy to weld, quiet, and inexpensive, the supply device 1 according to the present embodiment is designed to produce vibration damping parts materials (one material Wt and the other material Wt), as shown in FIG. This is a means for automatically stacking two sheets of material W2) and feeding them to the press 65.

More specifically, the carrier it is formed to be able to reciprocate in the directions of arrows A and B, and a plurality of magnets 13 are arranged on the carrier 11 at predetermined pitch intervals. Here, since the two materials Wl and W2 which are stacked on the downstream side of the crossing point R of the conveying means IO are simultaneously conveyed, the magnet 13 located downstream of the crossing point R is used to hold the two materials that are separated. In order to securely hold Wl and W2, it is formed so that the magnetic force is stronger than that of the upstream open magnet 13. In addition, the material support rail 12
is fixed to the base 2 in a state extending in the directions of arrows A and B, forming a conveying path for the conveying means 10. The advancing/retracting means 21 connects the carrier l1 to a link 27 which will be described later.
．． A reciprocating body 22 supported so as to be able to reciprocate in the directions of arrows A and B via 27 engages with a rack (not shown) formed on this reciprocating body 22 to reciprocate the reciprocating body 22 (therefore, the carrier 11). The rotating body 23 has a pinion (not shown) that rotates the rotating body 23, and a motor 24 that rotates the rotating body 23 in two directions, forward and reverse. therefore,
When the motor 24 is driven to rotate the rotary body 23 in two directions, forward and reverse, the reciprocating body 22 reciprocates in the directions of arrows A and B, and as a result, the carrier l1 also reciprocates in the same direction with a predetermined stroke via the links 27 and 27. move. The 1,000-stage elevator 26 includes links 27, 27, cylinders 28, and the like. The link 27.27 is connected to the reciprocating body 2 as shown in FIG.
The carrier 11 is connected to the reciprocating body 22 via a slider mechanism so as to be movable up and down in the directions of arrows C and D. Further, a cylinder 28 for rotating the link 27 is connected to the lower end of the link 27 on the left side in the figure. Therefore, when the cylinder 28 is driven to rotate both links 27.27 synchronously clockwise or counterclockwise, the carrier 1l moves in the direction of arrow C (or D) with its upper surface horizontal. do.

On the other hand, as shown in FIG.
etc. are included in the list. The transfer device 31 destacks a large number of stacked other materials W2, which have been transferred by the blank guide 33 from a direction perpendicular to the plane of the paper in the figure, from the supply site S of the transfer device 31 located at the other part 95. This is a chain conveyor that horizontally transfers the material to the feed device 41. On the other hand, the material W2 is transferred to the transfer device 4l by moving up and down the blank guide 33 and using the lid 32 at the replenishment site S. The destack feed device 41 is a means for sucking the uppermost one of the many stacked one-sided materials W2 transferred by the transfer device 31 and conveying it to a predetermined part of the delivery means 50. In this embodiment, the destack feed device 41 includes a front stopper 42 that positions the other material W2 at the destack center P, and a lifter cylinder device 43 that adjusts the vertical position of the other material W2 on the destack center P. , on the other hand, a material quantitative holding device 44 that holds a predetermined number of materials W2 at a predetermined horizontal position; A magnetic material separation device 45 separates the other material W2 held by the separation device 44 one by one, and the uppermost one of the other material W2 separated by the separation device 45 is attracted to a predetermined portion of the transfer means 50. A suction device 46 (distack cylinder 46a, magnetic suction tool 46b) that conveys the material W2 to the predetermined location, a two-sheet detection device 47 that detects whether there are two sheets of the other material W2 that have been transported and positioned at the predetermined location, and the like. It has been done. Further, the delivery means 50 transports the other workpiece W2 positioned at a predetermined part of the delivery means 50 to the intersection point R of both transport means 10. It is a means for placing the hand over cylinder and includes a magnet carrier 51, a roller 52, a grip jaw 54, a drive cylinder 55, a handover cylinder device 56, etc. The magnet carrier 51 is arranged in the direction of the arrow E so that the other material W2 positioned at a predetermined portion of the transfer means 50 can be transferred to the crossing point R while being attracted and held by magnetic action. More specifically, magnet carrier 5
1 is arranged so that when there is only one piece of the other material W2 to be suctioned and held, the material W2 can be positioned a predetermined distance above the one material W1 stopped at the intersection R, and the other material W2 is When there are two sheets of material W2, the material W2 is arranged to protrude in the direction of the arrow E by a predetermined length from the intersection point R so that the material W2 can be transferred to the two-sheet discharge packet 49 provided on the left side from the one-way conveying means 10. It is formed in In this embodiment, the distance between the crossover site R and the destack center P is formed to be as short as possible, and the two-sheet discharge packet 49 is arranged as close as possible to the crossover site R, and the magnet carrier 51 The length of is set to be the minimum. As a result, it is possible to reduce costs by saving material costs and processing costs, and on the other hand, it is possible to reduce the moving distance of the material W2 and speed up the work. On the other hand, material W
Furthermore, a large number of rollers 52 are rotatably provided on the lower surface of the blue paper 5l so that the other material W2 can be smoothly moved. ．． The grip jaw 54 is formed to be movable in the direction of arrow E while holding the other material W2 positioned at a predetermined portion of the delivery means 50.
4 is driven to move in the directions of arrows E and F by a drive cylinder 55, and moves the held other material W2 to the crossing region R or 2.
The movement stroke is switchable so as to move up to the sheet discharge packet 49. By the way, as shown in FIG. 4, the supply device 1 is provided with a control means 5 for driving and controlling the above-mentioned one conveying means 10, the other conveying means 30, the delivery means 50, etc. Panel 6 etc. are connected. Next, the operation of this embodiment will be explained based on the flowcharts shown in FIGS. 5(a) and 5(b). A start command is output to the control means 5 using the operation panel 6 shown in FIG. Then, in step SIO shown in FIG. 5(a), the control means 5 forms the material Wl by the punching press 60 shown in FIG. Then, in step 312, the control means 5 drives and controls the one-sided conveyance means 10 to convey the one-sided material W1 from the one-sided site 85 toward the press 65. That is, The control means 5
The motor 24 of the advancing/retracting means 2l shown in the figure is driven to rotate the rotating body 23 counterclockwise. Then carrier 11
is moved in the direction of the arrow A via the reciprocating body 22, and its tip is positioned at a predetermined position below the one-way material W1 set in the one-way part 85. Next, the control means 5
By driving the cylinder 28 of the lifting means 26 and rotating the link 27 on the left side in the figure clockwise, the carrier 1

2 by a predetermined amount in the direction of arrow C and hold it.

In this state, the control means 5 drives the motor 24 to rotate the rotating body 23 clockwise, thereby controlling the carrier 1.
1 by a predetermined stroke in the direction of arrow B, and the one workpiece W1 held at the tip of the carrier 11 is positioned at a predetermined position above the workpiece support rail l2. In this state, the control means 5 drives the cylinder 28 to rotate the link 27 counterclockwise, so that the carrier l
1 in the direction of arrow D. Then, the material W1 comes into contact with the material support rail 12, and is released from the support of the carrier 11 and placed on the support rail 12. In this way, by causing the carrier 1l to perform the above-described rectangular movement, the one-sided material W1 can be transferred from the one-sided location 85 onto the material support rail 12 of the one-sided conveyance means 10. Furthermore, by causing the carrier 11 to perform the rectangular movement described above, the one-sided material W1 newly set in the one-sided part 85 is transferred onto the material support rail 12, and the one-sided material W1 that has already been placed on the rail 12 is transferred. On the other hand, the material W1 can be moved in the direction of arrow B by an amount equivalent to the movement stroke of the carrier 11. By causing the carrier 11 to repeatedly perform rectangular movements in this way, the material W1 can be intermittently conveyed toward the press 65. At this time, the control means 5 controls the rectangular movement of the carrier l1 so that the one material W1 on the support rail 12 temporarily stops at the intersection R. Next, in step S14, the control stage 5 determines whether or not the material W1 has temporarily stopped at the intersection point R,
If the carrier 11 is stopped, the rectangular movement of the carrier 11 is interrupted and the material Wt is stopped at the intersection R until the material stacking operation is completed. On the other hand, if the material W1 is not stopped at the intersection point R, the process returns to step S12 and the material W1 is stopped at the intersection point R.
The carrier l1 is made to repeatedly perform rectangular motion until the carrier l1 reaches the intersection point R. Next, in step S15, it is determined whether the preparation for stacking the materials has been completed. Here, material stacking preparation is performed by executing steps 316 to S25 described below. That is, step S16 shown in FIG. 5(b)
Then, the other material W2 is placed in the blank guide 3 as shown in FIG.
3, the transport device 31
By positioning at the replenishment site S, the other site 95
Set to . Next, in step 318, the control stage 5 controls the other conveyance means 3.
0, the other material W2 is transferred in the direction of arrow E by the transfer device 31, and is brought into contact with the front stopper 42 of the destack feed device 41 and positioned at the destack center P. Next, in this state, the lift 1 cylinder device 43 raises the material W2 by a predetermined distance in the direction of arrow C, and the material quantitative holding device 44 holds a predetermined number of the other material W2, and the separating device 45 separates each material W2 one by one. To separate. Next, the destack cylinder 46a of the suction device 46 is driven to lower the suction tool 46b and the other material W on the uppermost layer is lowered.
2, and in this state, the suction tool 46b is raised by a predetermined distance in the direction of arrow C, thereby transporting the other material W2 to a predetermined portion of the delivery means 50. The other material W2 transported to a predetermined location is held by a grip jig E-54. At this time, the other material W2 is horizontally transferred from the Ikegata section 95 by the transfer device 31 without changing its posture, is vertically transferred by the destack feed device 41, and is positioned at a predetermined portion of the delivery means 50 before being transferred to the grip jaw.
54, the posture of the other material W2 does not change from that of the other part 95. Next, in step S20, the other material W2 or the delivery means 50
It is determined whether or not it is present at a predetermined location. If the other material W2 is not at the predetermined location, the process returns to step 16, and the control stage 5 drives the delivery means 50 until the other material W2 is conveyed to the delivery means 50.

On the other hand, if the material W2 is present at a predetermined location, step S22
Then, the two-sheet detection device 47 determines whether or not there is only one sheet of the other material W2 positioned at a predetermined position. If it is determined that there are two sheets of the other material W2, the process proceeds to step S24, and these two sheets of the other material W2 are discharged into the two-sheet discharge packet 49. In other words, in such a case, the other material W2 is discharged into the two-sheet discharge packet 49. A two-sheet detection signal is output to the control means 5 by the two-sheet detection device 247. In response to this, the control means 5 drives the drive cylinder 55 to move the two other materials W2 by a predetermined stroke in the direction of arrow E via the grip jaws 54 along the magnet carrier 51. is discharged to the discharge baguette 49 without stopping at the intersection point R. At this time, since the length of the magnet carrier 51 is the minimum, the magnet carrier 51 can quickly move to the arrow E.
It can be discharged by moving it in the direction. If it is determined that there are one pieces of the other material W2, the process proceeds to step S25, where the other material W2 is positioned at the intersection R, and preparation for stacking the materials is completed. That is, the control means 5 drives the drive cylinder 55 to move the other material W2 by a predetermined stroke in the direction of the arrow E via the grip jaw 54 to position it at the intersection R.

By the way, if it is determined in step S15 that preparation for stacking the materials is completed, the process proceeds to step 26, where the control means 5 drives the transfer means 50 to place the other material W2 on top of the one material Wl. That is, the holding relationship between the material W2 and the magnet carrier 51 is released by driving the handover cylinder 56 to lower the magnetic suction tool 56b to adsorb the other material W2 and push it down in the direction of arrow D, and release the holding relationship between the material W2 and the magnet carrier 51. 10 is placed on the other material W1. At this time, the one-sided material W1 is moved in one direction (arrow A, B direction) by the one-sided conveyance means 10 to reach the intersection point R.
, and the other material W2 descends while being reliably sucked and held by the suction tool 56b, so both materials Wl
, W2 are superimposed without changing their poses.
Note that if the material stacking preparation is not completed, the process returns to step S16 and the work of transporting and positioning the other material W2 is performed. Next, in step 328, the two stacked materials Wl and W2 are simultaneously transported downstream from the intersection R of the transport means 10 and fed to the feed bar 68 of the press 65. At this time, since the magnet l3 located downstream of the intersection point R of the conveying means 10 has a stronger magnetic force than the magnet 13 located upstream, both materials Wl and W2 are conveyed simultaneously without changing the relationship between the positions. It will be done. The two materials Wl and W2 supplied to the press 65 are press-molded to produce a vibration damping component in which an air layer is formed between the two materials Wl and W2. According to this embodiment, the one-way conveying stage 10 supplies the one-side material W1 from the one-side part 85 to the press 65;
The other conveyance stage 30 supplies the other material W2 from the direction intersecting the conveyance path in the middle of the conveyance path forming the one conveyance means 10 from the other place 95, and the other conveyance means 10. It is equipped with a delivery means 50 for taking over the other material W2 from the transporting means 30 and placing it on the one material Wl supported by the one transporting means 10, and for stacking downstream measurements from the intersection point R of the one transporting means 10. Ta2
Since the horizontal plate is formed so that two sheets of materials Wl and W2 can be conveyed at the same time, one sheet of material W1 is automatically used as a material for vibration damping parts.
and the other material W2 are stacked together and fed to the press 65 to produce a low-cost vibration-damping component that is easy to weld, has high quietness, and is highly quiet. Further, the one workpiece Wt is transported in one direction by the one hand conveying means 10 without changing its posture, and the other workpiece W2 is placed on the one workpiece Wl in a predetermined posture without changing its posture by the other conveyor Vi30 and the delivery means 50. After stacking these materials Wl and W2,
A vibration damping component can be manufactured quickly without the need for an operator to change the positional relationship between the two materials Wl and W2.

Furthermore, since the length of the magnet carrier 5l of the delivery means 50 is made as short as possible, it is possible to save on material costs and reduce costs. In addition, the other workpiece W2 taken from the other transport means 30 is quickly transported to the intersection point R, and the one workpiece W1 supported by the one transport means IO is a
In addition, it is possible to quickly perform the ejection operation into the two-sheet ejection packet 49. In addition, since the magnet 13 downstream of the intersection point R of the conveying means 10 is shaped so that its magnetic force is stronger than that of the magnet 13 upstream, the two stacked materials (
It is possible to reliably transport the material Wl on the one hand and the material W2 on the other hand simultaneously without changing their positional relationship. In the above embodiment, the material supply device 70 is installed at one location 85, and the transfer device 3 is installed at the other location 95.
Although the supply device 1 is constructed by arranging the supply portions S of 1, the supply device 1 can be controlled by installing any press material supply sources at one portion 85 and the other portion 95. For example, a coil material supply device may be installed at one location 85 and a blank material supply device may be provided at the other location 95, so that the supply device 1 can be omitted. In addition, although the supply device 1 was used as a device for automatically stacking two sheets of one material Wt and the other material W2 and conveying them simultaneously to the press 65, the supply device 1 can be used to selectively transfer different types of press materials. It can also be used as a device for feeding the press 65 at the same time. For example, a blank material feeding device may be installed at the one part 85 and a thin plate blank material may be fed to the press 6 by the conveying means 10.
Another blank supply device is installed in the other part 95 to form a thick plate blank material so that it can be supplied to the press 65 by the other conveying means 30 and the delivery means 50. Then, normally, a thin plate blank material is supplied to the press 65 by the conveying means 10 and press-formed.
When the mold of the press 65 is changed from one for thin plate blanks to one for thick plate blanks, the conveying means 10
It may be configured such that the driving of the plate is stopped and the thick plate blank material is immediately supplied using the Ikegata conveying means 30 and the delivery means 5o. This makes it possible to further speed up the press operation. [Effects of the Invention] According to the present invention, there is a one-way conveying means for supplying one material to the press from one part, and a direction intersecting the conveying path in the middle of the conveying path forming the one-way conveying means from the other part. and a transfer means for picking up the other material from the other transporting means and placing it on the one material supported by the one transporting means at the intersection of the two transporting means. , and because it is configured to be able to simultaneously convey two sheets of material stacked downstream from the intersection point of the one-way conveying means, it is easy to weld, is highly quiet, and is a low-cost vibration damper. To manufacture parts, two sheets of material can be automatically stacked and fed to the press.
