The present invention relates to a conveying apparatus for a rail support spring which is fixed to an inner surface of a cassette case of a magnetic tape and elastically presses the rail in one direction to support the rail in the correct position.

Conventional rail support springs are formed in a thin spring plate as a thin spring plate to lightly and elastically press the rails in the cassette case, and have a gentle angle on both sides so that the center of the rail can be pressed at both ends. Is bent.

This rail support spring is fixed one by one to the inner surface of the cassette case in the manufacturing process.

In the conventional apparatus, the stacked rail supporting springs are picked up one by one from the top and transferred to the inner surface of the cassette case, and are fitted to the projections formed on the inner surface of the cassette case, and the projections are fused to fix the cassette case. .

However, the rail supporting spring, which is a thin spring plate, has a drawback in that when the upper surface is sucked by the sucker and pulled up from the laminated position, the lower rail supporting spring is attached to the lower surface and comes up together, so that it cannot be pulled out exactly one by one.

The sticking phenomenon of the rail occurs in the manufacturing process by a thin oil film adhering to the rail surface or in a state in which the thin rail support springs are close to each other and no air can flow therebetween.

When several rails are conveyed at the same time, the following rails drop out during transport, or they are conveyed together on the inner surface of the cassette case, resulting in a malfunction.

In order to pull out the rail support spring correctly one by one, it does not hold the rail support spring of the uppermost stage, but maintains the rail support spring of two steps or less, and makes them not pull out, and the rail support spring of the highest stage It can be pulled out one by one by pulling up, or keeping two or less rail support springs horizontally unmovable, so that the rail support spring of the uppermost stage may not overlap horizontally.

However, it was difficult to accurately maintain the thin rail support spring of two or less stages except the uppermost one, and these mechanisms cannot realize the characteristic of accurately pulling out the rail support springs one by one.

The present invention has been made to solve the above problems, and an important object of the present invention is to reliably separate the uppermost rail supporting spring from two or less springs by effectively utilizing the elastic force of the rail supporting spring, and 1 The present invention provides a conveying device for a rail support spring that can be accurately picked up and conveyed sheet by sheet.

In addition, another important object of the present invention, in order to effectively use the properties of the unique material of the rail support spring, when pulling out, to prevent excessive force on the rail support spring, and to pull out one by one as an extremely simple structure. An object of the present invention is to provide a conveying device for a rail support spring.

The conveying apparatus of the rail support spring of the magnetic tape of this invention is a thin spring board, Comprising: The lamination | stacking means of the rail support spring of the magnetic tape in which the whole shape is formed in thin elongate board shape, and both sides are bent gently. And a conveying means for absorbing and conveying the upper surface of the overlapping springs stacked on the laminating means.

The conveying means includes a suction member that sucks both ends of the spring, a pressing member that presses the middle of the spring, a moving table on which the pressing member and the suction member are mounted, and a lifting member relatively freely moving relative to the pressing member. Has a detachable member.

The pressing member presses the middle of the spring, while the absorbing member sucks both ends of the spring, and the separating member pulls up both ends of the spring relative to the middle, thereby forcibly separating both ends of the laminated spring. After that, it is pushed out from the lamination position.

The transfer apparatus of this invention adsorb | sucks and conveys both ends of a rail support spring to an adsorption | suction member.

The uppermost one of the stacked rail supporting springs is attracted to the upper surface and is pulled out one by one from the top.

The suction member sucks both ends of the rail support spring, and the pressing member pushes the middle thereof.

In this state, the separating member raises the suction member relatively to the pressing member.

Accordingly, the rail supporting spring in the laminated state has only the uppermost one bent thereto and separated from the lower one.

That is, the uppermost rail support spring, which is pressed in the middle by the lower rail support spring, and both ends are pulled up, and is elastically curved along the upper side, is curved with a different radius of curvature from the upper surface of the rail support spring at the bottom. In this way, the adhered state is reliably released.

For this reason, the rail support spring which closely adheres through an oil film or is in the state without an air layer in the middle is forcibly peeled off by elastic deformation.

The uppermost rail supporting spring separated from the lower rail supporting spring is pulled up by one piece and conveyed.

In a state where the laminated rail supporting springs are separated, they are bent and elastically deformed.

Since the rail supporting spring is formed of a spring plate, and is a thin plate that is easy to adhere but easily deformable, excessive force is not exerted on the rail supporting spring at this time, it can be easily deformed, and it is possible to realize that the single piece is pulled out reliably. have.

Therefore, in order to pull out one by one, it can be pulled out without damaging a rail support spring or causing a torsional deformation.

In addition, in order to effectively use the properties of the material capable of elastic deformation of the rail support spring, the overall structure is considerably simplified compared to the structure in which the rail support spring of two stages or less is held therein. The transfer can be made extremely simple.

Therefore, the conveying apparatus for the rail supporting spring of the magnetic tape of the present invention has a simple structure, and can securely convey the rail supporting springs one by one, thereby realizing a particularly important feature in the automatic granulator.

Hereinafter, embodiments of the present invention will be described in detail by the accompanying drawings.

As shown in Fig. 2, the stacking means 2 forms vertical walls facing each other, and the rail supporting springs 1 are stacked and overlapped between the vertical walls.

The vertical wall extends perpendicularly to the center of the inner side, and a projection piece 26 into which both grooves of the rail support spring 1 are fitted is formed.

The conveying means 3 includes an adsorption member 4 for adsorbing both ends of the rail support spring 1, a press member 5 for pressing the middle of the spring 1, a press member 5 and an adsorption member ( The movable table 6 to which the 4) is mounted and the separating member 7 to which the suction member 4 is mounted on the movable table 6 are freely lifted relative to the pressing member 5.

As shown in FIG. 3, the suction member 4 is attached to the movable table 6 so as to freely move up and down.

The suction member 4 forms a sucker 8 formed in a cup shape as a flexible rubber-like elastic body on the lower surface, and the sucker 8 is fixed to the lower ends of the upper and lower rods 9.

The upper and lower rods 9 penetrate through the air passage 10 itself, and the lower end of the air passage 10 is connected to the suction plate 8 and the upper end is connected to the connection hole 11 of the air hose. It is supposed to work.

The upper and lower rods 9 are attached to the movable table 6 via a sliding cylinder 12 having a small frictional resistance.

The suction member 4 is attached to the movable table 6 by a distance shorter than the entire length of the rail support spring 1 so as to be attracted to the upper surfaces of both ends of the rail support spring 1, and both sides are bent. As shown in FIG. 1, the suction plate 8 may be in close contact with the upper surface of the rail supporting spring 1, and the suction position is not shifted when the rail supporting spring 1 is deformed. It is mounted on the movable table 6 to move freely downward.

The pressing member 5 has two projections 14 guided to the fixing hole 13 formed in the center of the rail support spring 1, and the projections 14 are free to move up and down. The cylinder 15 inserted is formed.

The two projections 14 are formed in a tapered shape in which the front end ends, and is guided to the fixing hole 13 of the rail support spring 10.

In this way, the pressing member 5, in which the front end of the projection 14 is guided to the fixing hole 13, can be pulled up by the suction member 4 by attracting both ends, so that the rail supporting spring 1 is out of position. There is a feature that can be pressed.

In addition, according to the present invention, when the pressing member is not specific to the structure for pressing the fixing hole of the rail supporting spring, the entire shape that can press the middle of the stacked rail supporting spring can be used when pulling up both ends to the suction member. Not to mention that.

The two projections 14 are located immediately above the fixing hole 13 when both of the adsorption members 4 are located directly at both ends of the rail support spring 1 in the middle of the adsorption member 4. It is attached to the movable base 6 so that it may be located.

In addition, the two projections 14 are mounted in the cylinder 15 fixed perpendicularly to the movable table 6 so as to freely slide up and down, and are pushed by the coil spring 16 in the cylinder 15. It's coming out.

Therefore, the projection 14 forms a flange at the upper end, and the cylinder 15 has a lower and narrow opening at the lower end, thereby preventing the projection 14 from being pushed out.

When the pressing member 5 descends on the rail support spring 1, the protrusion 14 is guided to the fixing hole 13, and as the lower end of the cylinder 15, of the rail support spring 1. Press the top side. In this state, the adsorption member 4 is pulled up to the separating member 7 so that both of the uppermost rail support springs 1 are forcibly separated from the rail support springs 1 of two stages or less. .

As the separating member 7, an air cylinder 17 having the structure shown in FIG. 3 can be used. As for the air cylinder 17, the front end of the plunger is fixed to the rod 9 above and below the adsorption member 4, and itself is fixed to the movable base 6. As shown in FIG.

When the plunger of this air cylinder 17 is pulled in, the adsorption member 4 is pulled up, and both ends of the rail support spring 1 are elastically deformed upward to bend.

In place of the air cylinder 17, the whole member 7 which can separate | raise the adsorption member 4 can be employ | adopted as the separating member 7.

The conveying means 3 forms a moving table 6 on which the suction member 4 and the pressing member 5 are mounted, and moves the moving table 6 up and down, and at the same time, the rail supporting spring ( 1) is adsorbed and transported to the position where the cassette case is located.

As shown in FIG. 1, the moving means 3 has an upper and lower shaft 18 on which the movable table 6 is fixed to the lower end, and the upper and lower shafts 18 intersect the linear motion bearings. A cylinder (19) adapted to be inserted through the cylinder, a movable arm (20) on which the cylinder (19) is fixed vertically, a feed shaft (21) on which the end of the movable arm (20) is fixed, and the transfer The shaft 21 forms a pedestal 22 which is supported so as to freely move and move up and down.

The upper and lower shafts 18 have flanges formed at the lower ends thereof, and the pressing springs 23 are fitted between the flanges and the moving arm 20 so as to pass through them.

The pressing spring 23 elastically presses the movable base 6 downward. The upper end of the upper and lower shafts 18 protrude from the cylinder 19, and the positioning arms 24 are fixed thereto.

The positioning arm 24 extends horizontally and is fixed to the upper and lower shafts 18 and slides up and down along the guide rod 25 fixed to the moving arm 20 and fixed in the vertical direction. Move.

The upper and lower shafts 18, on which the positioning arms 24 are fixed at the upper ends, are prevented from rotating by this, so that the pressing member 5 and the suction member 4 are properly aligned with the rail supporting springs 1. And the lowering position of the up and down shafts 18 is determined at the moving arm 20 rising position.

Although not shown, the lower end of the feed shaft 21 is connected with a driving means which rotates the same as it moves up and down.

The operation of the conveying device of the rail support spring 1 having the above structure goes through the following process.

(1), a predetermined number of rail support springs (1) are stacked and stacked on the stacking means (2), and in the state in which the feed shaft (21) is raised, it is rotated to rail support the suction member (4) and the pressing member (5). Feed just above the spring (1).

(2) The feed shaft 21 does not rotate and descends to guide the projection 14 of the pressing member 5 to the fixing hole so that the suction member 4 sucks both ends of the rail supporting spring 1.

At this time, the upper and lower rods 9 of the suction member 4 are in the lowered position.

In this state, the suction plate 8 of the suction member 4 is fitted into the vacuum pump, and the suction plate 8 is held on the upper surface of both ends of the rail support spring 4 by suction.

The feed shaft 21 drops uniformly regardless of the stacking height of the rail support spring 1.

Therefore, when the number of laminations of the rail supporting spring 1 is large and the rear surface of the rail supporting spring 1 at the uppermost level is increased, the upper and lower shafts 18 are raised relative to the cylinder 19, so that the pressing members are always pressed. (5) and the adsorption member (4) can be brought into contact with the upper surface of the upper rail support spring (1).

(3) The suction member (4) is held in a state where the rail supporting spring (1) is sucked, and the rod (9) is pulled up and down of the suction member (4), and the upper end of the rail supporting spring (1) is lifted up. Curve in the direction.

The shape of the rail support spring 1 which is bent upward and bent back changes the shape of the rail support spring 1 at the lower end and releases the close contact state.

(4) The up and down rods (9) are held in the ascending position, the feed shaft (21) is raised, and the one rail support spring (1) is attracted and pulled out.

The sucked rail support spring 1 is rotated at a predetermined angle in the lifted state of the feed shaft 21, and is conveyed just above the mounting position of the cassette case.

(5) The feed shaft 21 is lowered, and the rail support spring 1 is transported to the correct position of the cassette case, after which the suction member releases the suction state.

(6) After that, the feed shaft is raised to return to the process of ①, and the process of ① to ⑤ is repeated to convey the rail support spring 1 to the correct position of the cassette case.

The cassette case in which the rail support spring 1 is set is conveyed to the next process after fixing the rail support spring 1 or not, and instead, the cassette case other than the rail support spring 1 is set.

The lamination means 2 which laminates several rail support springs 1 laminates and fills a predetermined number of rail support springs 1 after the whole rail support springs 1 have been transferred or exits, or in advance. The support spring 1 is replaced with a lamination-filled lamination means.

In the above embodiment, when the uppermost rail supporting spring 1 is detached from the second stage, the pressing member 5 is stopped and the suction member 4 is pulled up.

In addition, when removing the uppermost rail supporting spring, it is also possible to stop the suction member and lower the pressing member.

In this case, when the pressing member falls, the stacked rail supporting springs also drop, so that the stacking means is accommodated in a state where the laminated rail supporting springs can drop.
