Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc-shaped component feeder.

[0002]

[Prior art and its problems]

 For example, there is a case where it is desired to supply one disk-shaped component made of metal having an outer diameter of 25 mm and a thickness of 1.5 mm to the next process one by one at high speed. Conventionally, for example, in such a case, a linear vibrating feeder having a linear trough is used, and a hopper storing a large number of such disc-shaped parts is arranged above the part supply end of this trough, The disk-shaped parts to be discharged are linearly vibrated and transferred by the trough of the lower linear vibration feeder, and a wiper is provided near the discharge end of this trough so that they can be fed to the next process without overlapping one by one. It is possible to make it. When transferring at a low speed, there is no problem, but when transferring at a high speed, it goes without saying that the disk-shaped parts are cut out from the hopper at a high speed and transferred sequentially toward the wiper. Since only one disc-shaped component can be discharged to the outside from here, many disc-shaped components may overlap with each other in contact with the wiper. In such a case, there is no problem if the coefficient of friction between the transfer surface of the trough and the back surface of the disk-shaped component is small, but it is natural that it has a certain degree of frictional force. The frictional force between the troughs and the transfer surface may be too large and the lowermost disc-shaped part may not be transferred due to vibration. Alternatively, it is considered that the transfer speed becomes extremely low. That is, not only the supply to the outside is interrupted, but also the disk-shaped parts are transferred to the wiper one after another on the trough due to the vibration, and a large amount is accumulated between the hopper and the wiper. This may cause a large load on the vibration feeder, possibly damaging the drive unit and the movable unit.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and provides a disc-shaped component feeder capable of reliably feeding, for example, a metal disc having an outer diameter of 25 mm and a thickness of 1.5 mm to the next step at a high speed. The purpose is to do.

[0004]

[Means for solving problems]

 The purpose of the above is to store a large number of disc-shaped parts and a plurality of trough members arranged below the discharge port of the hopper and having a semicircular cross-section, and incline them upward in the component transfer direction. A first trough portion connected to each other with a step, and a second trough portion connected to the first trough portion and having a linear flat surface with a width slightly larger than the diameter of the disc-shaped component, A wiper member provided near the discharge end of the second trough portion for passing the disc-shaped component in a single layer, and the first and second trough portions are obliquely vibrated to transfer the disc-shaped component. And a disk-shaped component feeder comprising a vibrating section for causing the vibration.

Alternatively, a bowl having a flat bottom surface for storing a large number of disc-shaped parts and a torsional vibrating portion for torsionally vibrating the bowl around its center are provided, and the bowl bottom surface of the bowl is A recess having a width slightly larger than the diameter of the disk-shaped component is formed on the outer peripheral portion, and the recess is connected to the recess on the outer peripheral wall of the bowl and is larger than the thickness of the disk-shaped component. This is achieved by a disc-shaped component feeder characterized in that slits smaller than twice are formed.

[0006]

[Action]

 The first trough part has a semicircular cross section and is inclined upward in the transfer direction and is connected to a plurality of steps with steps. From the hopper for storing a large number of disc-shaped parts, the first trough part is connected. It is discharged on the upstream side of the section and is transferred by vibration by the vibrating section, but the disk-shaped parts are sequentially discharged from the hopper. Due to the upward inclination, a large number of disc-shaped parts that are overlapped between the hopper and the first trough part, so to speak, are gradually advanced while undergoing a loosening action. Further, due to the step, this loosening action is promoted, and when it drops from the trough member on the discharge end side to the second trough part, it is possible to go straight by vibration with a few sheets overlapping, and therefore at the wiper place. Only the lowermost disc-shaped component can be smoothly transferred by vibration and supplied to the outside. The disk-shaped parts that follow are overlapped parts, or if they do not overlap, they can fall from the last trough member and the following disk-shaped parts can pass through the wiper and be supplied to the outside. ..

Further, since each trough member of the first trough portion has a semicircular cross section, only the lowermost disc-shaped component is transferred by vibration while abutting and supporting both edge portions of the trough member. The parts are transferred on the lowermost disk-shaped part without contacting these trough members or almost without contacting them. Therefore, the lowermost component is transferred by vibration more quickly, and the single layer discharge from the wiper can be performed very smoothly.

In another embodiment, the bowl vibrates in a torsional manner, so that a large number of disk-shaped parts stored in the bowl are transferred in the clockwise or counterclockwise direction while receiving centrifugal force and formed on the outer peripheral portion. When it reaches the recess, it is transferred in the same direction while being subjected to the same torsional vibration, and can be supplied to the outside one by one from the slit. Also, the disc-shaped component that overlaps with this is abutted by the wall on the slit side of the recess to stop the movement, but the disc-shaped component that is above it receives torsional vibration of the bowl, As it continues to rotate in the same direction, the walls of this slit do not overlap three or more disk-shaped parts. Therefore, there is no problem that a large pressing force is applied to the lowermost disc-shaped component from the slit and it cannot be led out through the slit due to torsional vibration. Therefore, it is possible to feed the disk-shaped parts in a single layer from the bowl to the next process at high speed.

【Example】

 Hereinafter, a disc-shaped component feeder according to an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 to 3 show a first embodiment of the present invention. In the drawings, a disc-shaped component feeder is indicated by 1 as a whole, and mainly a linear vibrating feeder 2 and its feeding end are shown. And a hopper 3 arranged above. Although the hopper 3 is shown in a reduced size for the sake of clarity, it actually has a much larger shape than the linear vibrating feeder 2. The linear vibration feeder 2 is mainly composed of a trough section 4 and a vibrating section 5 for vibrating the trough section 4. The trough section 4 is composed of a first trough section P and a second trough section Q, and a first trough section P. Is made of synthetic resin, and is composed of trough members 16, 17 and 18 having a semicircular cross section, which are arranged so as to be inclined upward by several degrees in the transfer direction by vibration as shown in FIG. Also, they are connected with a step. These are screwed and fixed to the trough support member 6 by screws 21, and the left end surface of the leftmost trough member 16 is closed by an end plate 19 made of metal. The second trough portion Q is formed with a step on the last trough member 18 of the first trough portion P on the upstream side, is integrally formed on the trough support member 6, and has a linear and flat transfer surface 20. is doing.

Further, a rectangular rubber plate 22 as shown in FIG. 3 is fixed to the frame 23 by bolts above the intermediate portion of the last trough member 18 of the first trough portion P. The frame 23 is fixed to the trough support member 6 with bolts as shown in FIG.

A semicircular gap G as shown in FIG. 3 is formed between the rubber plate 22 and the trough member 18, and the disk-shaped component m is transferred to the trough member 18 while maintaining a horizontal state. The gap formed between the upper surface and the lower edge of the rubber plate 22 when being pressed is smaller than the thickness of the disk-shaped part m. That is, if the elasticity of the rubber plate 22 is considerably large, the rubber plate 22 is transferred to the downstream side in a single layer.

As shown in FIG. 2, a wiper blade 25 is fixed near the discharge end of the second trough portion Q to the trough support member via a pair of left and right cross-section mounting members 24a and 24b. .. The gap s between the wiper blade 25 and the transfer surface 20 is larger than the thickness of the component m as shown in FIG. 2, but smaller than this.

Next, the vibrating section 5 arranged below the trough section 4 configured as described above will be described. This has a known structure and is connected to the base block 11 by a pair of front and rear leaf springs 9 and 10. Leaf spring mounting blocks 7 and 8 are integrally formed on the lower surface of the trough support member 6, and the upper ends of the leaf springs 9 and 10 are fixed to these by bolts. A movable core 13 hangs down from the trough support member 6, and an electromagnet 15 around which an electromagnetic coil 14 is wound is fixed to the base block 11 with a gap therebetween. The entire linear vibrating feeder 2 is supported on the floor by a vibration-proof rubber 12.

The first embodiment of the present invention is configured as described above, and its operation will be described below.

It is assumed that a large number of disk-shaped parts m are stored in the hopper 3. When an alternating current is applied to the electromagnetic coil 14, an alternating attractive force is generated between the electromagnetic coil 14 and the movable core 13, whereby the trough portion 4 linearly vibrates in the direction of arrow a. As a result, the parts m are supplied one after another from the hopper 3, and in the first trough part P, these parts swing only left and right in the trough members 16, 17 and 18, and only the lowermost part m has its both ends. Although the parts are supported and are transferred at high speed by vibration, the transfer speed is smaller because the parts m overlapping with these parts are not supported by the trough members 16, 17, and 18, and therefore the transfer speed is smaller. During the transfer of the trough part P, the disk-shaped part m cut out in large quantities from the hopper 3 is transferred at the highest speed in the lowermost part m, and since it is a semi-circular trough, it swings in the transfer direction. While being transferred and each trough part 16, 17, 18 is connected with a step difference, if a large number of overlapping trough parts are transferred when they fall down this step, they are loosened, so to speak, to the downstream side. Is Since the third trough member 18 is transferred at a density smaller than that on the flow side, at most about several sheets are overlapped in the third trough member 18, and the lower side of the rubber plate 22 is transferred to pass almost one by one. Will be done.

From the third trough member 18 to the second trough portion Q having a flat transfer surface, it is transferred at a high speed due to its flatness, and continuously under the wiper blade 25 in a single layer to the next step. Can be supplied. Further, as it passes through the wiper blade 25, as shown in FIG. 1, two or three sheets overlap each other, so that the frictional force of the lowermost disc-shaped component m does not make it difficult to transfer. It can smoothly pass under the wiper blade 25.

The first embodiment of the present invention has the above-described actions and effects, and further has the following effects.

In other words, depending on the transfer speed, the rubber plate 22 is used to transfer a single layer to the downstream side depending on the transfer speed. However, even if the rubber plate 22 is not a single layer, it functions to adjust the flow rate of the disk-shaped component, In addition, it serves to prevent a large number of disc-shaped parts m from reaching the wiper blade 25. Further, since the first trough section P is inclined upward in the transfer direction, the transfer speed is small. Therefore, if this section is also considered to be a part of the hopper, the function of the wiper 25 in the trough section Q is surely secured. You are working to ensure that you do it.

FIG. 4 and FIG. 5 show a second embodiment of the present invention. This component supplying apparatus is shown by 30 as a whole, and has a flat cylindrical bowl 31 and is integrally fixed to the bowl 31. The guide track portion 32 is provided. A known torsional vibration drive unit is provided below the bowl 31. That is, the bowl 31 is connected to a plate spring 34 which is inclinedly arranged at an equal angular interval with the base block 33, and an electromagnet 36 around which a coil 35 is wound is fixed on the base block 33, and a gap is formed between the electromagnet 36 and the base magnet. The base block 33, on which the movable core 37 is placed and fixed to the bottom surface of the bowl 31, is supported on the floor by the vibration-proof rubber 38. The torsional vibration drive unit is configured as described above, but the whole is covered by the cylindrical cover 50. The movable core 37 is integrated with the bowl 31 by bolts 39.

The bowl 31 has a circular shape as shown in FIG. 4, but a recess 31a is formed in the outer peripheral edge thereof, and the depth thereof is shown in FIG. A slit 60 is formed, and the height of the slit 60 is larger than the thickness of the component m 1 as shown in FIG. 5, but smaller than this. Also, the thickness of the bottom wall of the bowl 31 projects slightly above the thickness of the two overlapping parts m, but if there is an overlying part m, vibration will cause this. The level difference is transferred to the right side in Fig. 5 by a small jump motion. In addition, the orbital motion shown by the arrow B in FIG. 4 is continued.

The second embodiment of the present invention is constructed as described above, and its operation will be described below.

Although the parts m are shown scatteredly in FIG. 4, they are actually stored at a higher density. When alternating current is applied to the coil 35, an alternating attractive force is generated between the electromagnet 36 and the movable core 37, which causes the bowl 31 to perform a known torsional vibration. As a result, the component m in the bowl 31 receives the force transferred in the direction indicated by A. In addition, the part m at the outer peripheral edge in the bowl 31 is also transferred in the same direction as the arrow A. Especially, the part m at the outer peripheral edge is transferred while abutting on the inner peripheral wall of the bowl 31, and this is recessed. When reaching the location 31a, the lowermost part m falls here. Further, the part m which is superposed on this also falls here, but the part m which is further superposed is transferred in the direction of the arrow B while maintaining the same level as the bottom surface 31b of the bowl 31.

The lowermost part m in the recess 31a is transferred in the same direction as the arrow B while being subjected to the torsional vibration of the bowl 31, but when it reaches the slit 60, it passes through the guide track 32. It is supplied to the outside one by one from the street discharge port 32a. Further, the disk-shaped component m immediately above is brought into contact with the bottom wall portion of the bowl 31 as shown in FIG. 5 and stopped there. However, the part m mounted on this will continue its orbital motion.

As described above, three or more components are not always overlapped in the recess 31a, and therefore, a large pressing force is applied to the component m passing through the slit 60, so that the component m cannot be transferred. There is no.

The same applies to the first embodiment, but in the case where some marks or numbers are engraved on both sides of the disk-shaped component m, even if there is an overlap of three sheets, it will move to the lowermost component m. A large frictional force acts between the transfer surface and the transfer surface, making it more difficult to transfer the transfer surface. Therefore, the effect of the present invention is extremely remarkable.

Although the embodiments of the present invention have been described above, needless to say, the present invention is not limited to these, and various modifications can be made based on the technical idea of the present invention.

For example, in the above-described first embodiment, the first trough portion P has trough members 16, 17, 18 having a semicircular cross section arranged with a step and inclined upward, but these are different inclined surfaces. It may be provided with a step, and although it is made of synthetic resin, it may be made of metal. However, the load of the vibrating section 5 is smaller when the synthetic resin is used.

[0029]

[Effect of the device]

 As described above, the component feeder according to the present invention can feed the disc-shaped components in a single layer one by one, continuously and at high speed to the next process. It is especially effective when the friction coefficient of the surface is large.
