Description

  The present invention relates to a technique for dispensing a thin plate used, for example, in a separator for a vehicle transmission.

Conventionally, a thin steel plate used for a vehicle transmission separator is as thin as about 1.2 mm, but it is hard with an iron-based plate material, and about 50 sheets are laminated and delivered as a set from a manufacturer. Yes. Then, after the laminate is carried to the line side, it is taken out so that the operator peels it one by one and is attached so as to be sandwiched between the main body and the torque converter case.
In general, as a technique for taking out the laminated thin plates such as a printed board and a lead frame one by one, for example, a technique of vacuum-sucking the uppermost thin plate and taking it out upward (see, for example, Patent Document 1). In this case, in order to prevent the two sheets from being lifted at the same time, a technique in which the end of the thin plate is brought into sliding contact with the peeling roller to peel off the second sheet (see, for example, Patent Document 2). ) Etc. are also known.

Japanese Patent Laid-Open No. 10-329967 JP 2001-310834 A

However, as described above, in the case of a device that takes out one piece at a time by vacuum suction, the size of the device increases depending on the type of work to be handled, etc. There was a problem of being.
In addition, since the holes in each place are processed with a press, the plate is often distorted or twisted, which is an obstacle to automation, and when chips etc. are attached to the front and back surfaces, After assembly, the valve hole of the main body may be clogged, resulting in poor quality.

  Therefore, the present invention can automatically pay out one sheet at a time even when the flatness is distorted or twisted, and can be removed cleanly even if there is dust or foreign matter on the front and back surfaces. The purpose is to do so.

  In order to achieve the above object, the present invention provides a lifting / lowering means capable of moving up and down a laminate, and a reference member for regulating the upper surface position of the rising laminate in an apparatus for paying out thin plates stacked one by one. And a pressing means for applying a pressing load of a predetermined pressure to the laminate through the reference member, and an extrusion means for extruding the uppermost thin plate of the laminate in the horizontal direction.

  Then, when the laminate is raised by the elevating means, the upper surface position of the laminate is regulated by the reference member, and a predetermined pressing load is applied to the laminate via the reference member, thereby causing distortion or twisting. However, if the uppermost thin plate is always placed at the same position and then the uppermost thin plate is pushed out by the pushing means, only one sheet can be dispensed accurately.

In the present invention, the dispensing device is provided with a removing means for removing foreign substances adhering to the front and back surfaces of the extruded thin plate.
In this way, if the foreign matter is removed by the removing means, a series of operations from taking out one sheet at a time to cleaning is performed smoothly, and there is no possibility of causing quality defects.

The laminate in which the thin plates are stacked one above the other is lifted by the lifting means, the upper surface position of the laminate is regulated by the reference member, and a presser load with a predetermined pressure is applied to the laminate via the reference member, thereby In this state, the uppermost thin plate is extruded in the horizontal direction, so that only one sheet can be automatically paid out accurately.
At this time, if foreign matter adhering to the front and back surfaces of the extruded thin plate is removed by the removing means, problems such as poor quality can be prevented.

Embodiments of the present invention will be described with reference to the accompanying drawings.
Here, FIG. 1 is a schematic configuration diagram of the entire dispensing apparatus according to the present invention, and FIG. 2 is a plan view thereof.

  The laminated thin sheet dispensing device according to the present invention is configured as a device that dispenses the laminated thin plates used for the separator in the vehicle transmission one by one, and ensures that the thin plate W having fine distortion and twist is reliably pressed by pressing. You can pay out one by one.

  The laminated sheet is about 1.2 mm thick, and about 50 sheets are stacked up and down and delivered from the manufacturer. Since it is an iron-based material, it is hard, but as shown in FIG. Since these holes are processed with a press or the like, they are slightly distorted and twisted.

  As shown in FIG. 1, the payout device 1 includes a cutting machine 2 that cuts out the thin plates W one by one from the laminate in which the thin plates W are stacked, and a removing machine 3 that is disposed downstream of the cutting machine 2. The dust or foreign matter adhering to the front and back surfaces of the thin plate W cut out from the cutting machine 2 is removed by the removing machine 3 and then discharged.

  The cutting machine 2 includes a lifting platform 5 on which a laminate is placed and can be moved up and down by a lifting cylinder unit 4 as a lifting means, a front stopper 6 for regulating the front surface of the stack, and a stack when the stack is raised. A reference member 7 for regulating the position of the upper surface of the object, a pressing means 8 for applying a pressing load to the laminate through the reference member 7, and an extrusion means 10 for pushing the uppermost thin plate W forward are provided. .

  The reference member 7 includes a reference plate 11 and a plurality of rollers 12. In this embodiment, as shown in FIG. 2, the rollers 12 are provided at four locations on the rectangular reference plate 11. Is in contact with the uppermost thin plate W so that the frictional resistance is reduced when the thin plate W is pushed out by the pushing means 10.

  The pressing means 8 includes a pressure receiving material 13 having a tapered upper surface fixed on the reference plate 11, a wedge material 14 movably disposed on the pressure receiving material 13, and the wedge material 14 in the taper direction. A press cylinder unit 15 that can be moved along the press cylinder unit 15 is provided, and the press load applied to the pressure receiving material 13 can be increased or decreased by operating the press cylinder unit 15.

  The extruding means 10 includes a thin extruding arm 16 and an extruding cylinder unit 17, and only the uppermost thin plate W can be extruded by the operation of the extruding cylinder unit 17. In order to send W downstream, a pair of feed rollers 20 are provided on the downstream side of the thin plate W.

Further, the height of the front stopper 6 is set so as to allow only the uppermost thin plate W to pass therethrough and prevent the second and lower thin plates W from passing therethrough.
Further, a first sensor 18 is provided in the vicinity of the reference plate 11 of the cutting machine 2 as described above, which can detect the proximity when the laminate is lifted and comes into contact with the roller 12 of the reference plate 11. Yes.

  The remover 3 is made of hard rubber that can remove dust and foreign matters on the front and back surfaces of the thin plate W fed by the feed roller 20 and faces the upper and lower surfaces of the thin plate W with a predetermined clearance c. Each of the front and rear partition members 21, a suction mechanism 22 that sucks air from the space between the front and rear partition members 21, and a filter 23 disposed in the middle of the suction path. A pair of feed rollers 24 is provided downstream of the first roller.

Then, when the thin plate W is fed into the partition member 21 through the front feed roller 20, the suction mechanism 21 sucks air from the outside through the clearance c, and sucks dust, foreign matter, etc. adhering to the front and back surfaces of the thin plate W, The filter 23 is used for capturing.
A non-contact second sensor 25 for detecting the passage of the thin plate W is provided on the downstream side of the rear feed roller 24.

A method for paying out the thin plate W by the payout device 1 will be described.
After the laminate is placed on the elevator 5, the elevator cylinder unit 4 is operated to raise the elevator 5, and the uppermost thin plate W is brought into contact with the roller 12 of the reference plate 11. At this time, the pressing cylinder unit 15 is set at a position where the pressing force is relaxed, and the wedge member 14 is positioned on the right side in the figure. However, when the first sensor 18 detects the proximity of the thin plate W, the pressing cylinder unit 15 is pressed. By operating the cylinder unit 15 to attract the wedge member 14 and applying a predetermined pressing force, the thin plate W is prevented from being distorted or twisted, and at the same time, the suction mechanism 22 is operated to start sucking air.

Next, the extrusion cylinder unit 17 is operated to push out the uppermost thin plate W, and at the same time, the feed roller 20 is operated. To do. Then, the extruded thin plate W passes through the partition member 21 of the removing machine 3, is discharged from the feed roller 24 in a state in which foreign matter on the front and rear surfaces is removed, and is conveyed downstream.
When the second sensor 25 detects the discharge of the thin plate W, the operation of the feed roller 24 is stopped, and the suction of air in the suction mechanism 22 is stopped.

  This is the end of one cycle, and the next thin plate W is dispensed according to the same procedure as described above, but the stack is lowered to the bottom stop point every cycle by the operation of the lifting cylinder unit 4 and then raised. Since the pressing plate is pressed against the roller 12 of the reference plate 11 and a constant pressure is always applied by the pressing cylinder unit 15, distortion and twist of the thin plate W are forcibly corrected, and at the same time, the uppermost thin plate W is moved to a fixed position. Can be set.

  Further, since the thin plate W is pressed by the roller 12 of the reference plate 11, the frictional force is small, and the extrusion arm 16 having a small thickness can be extruded.

In addition, this invention is not limited to the above embodiments. What has substantially the same configuration as the matters described in the claims of the present invention and exhibits the same operational effects belongs to the technical scope of the present invention.
