Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a micro-joint separating apparatus, and more particularly to a technique of vibrating a processed product in which a base material and a product are connected by a micro-joint to separate a micro-joint portion and separate the product into a single product. Things.

[0002]

2. Description of the Related Art Conventionally, in a micro-joint separation apparatus, for example, disclosed in Japanese Utility Model Application Laid-Open No. 6-523, both ends of a processed product are fixed on a vibration base 1 by clamps 2, and the center of the processed product is suspended in the air. In this state, vibration is generated by the vibration generator 3 and transmitted to the processed product via the vibration operation restricting device 5. Then, the micro joint portion of the processed product is separated by the vibration, only the product falls on the product delivery conveyor, and only the product is stored at a time. This eliminates the need for manual processing of individual products, significantly improving work safety and productivity, and is not restricted by product placement or shape.
The product can be processed in units of processed products without causing deformation or damage. Further, since the configuration of the apparatus is simple, automation and unmanned operation are possible in relation to the apparatus for the preceding and following processes.

However, in the above-mentioned conventional technology, firstly, since the product separated by vibration falls from a high place, the product may be damaged or deformed, and may be scattered around. Second, the work must be fixed and removed by the clamp 2 each time, and the operation is complicated. Third, since both ends of the processed product are fixed and the center floats in the air, the products may not be evenly separated. Fourth, there is a disadvantage that the noise from the vibration generator 3 or the like is intense and gives the operator fatigue.

[0004]

SUMMARY OF THE INVENTION Therefore, the inventions according to claims 1 to 7 are to prevent deformation and scattering of products,
Simplify the work of processed products. It is an object to separate products evenly and to prevent noise.

[0005]

SUMMARY OF THE INVENTION In view of the above points, the invention according to claim 1 provides a table provided with a top plate having a plurality of projections, and a vibration generator provided on the back side of the top plate. And a cover provided on the table so as to be openable and closable. With such a configuration, the processed product wrapped in the top plate and the cover,
The micro joint is separated by being vibrated by the vibration generator, and the base material and the product can be separated. Along with that, due to the rotation of the vibration generator, it slightly moves in the rotation direction. The advantage of this is that the input port for processed products can be made flat. Therefore, the processed product vibrates while being wrapped by the top plate and the cover (the processed product is not restrained at all, that is, is placed on the top plate), so that the product is deformed or scattered. Is prevented, and the products can be evenly separated. In addition, since it is only necessary to raise the processed product on the top plate and close the cover, the work of the processed product can be simplified. In addition, stainless steel is suitable for the top plate and the convex portion, but the present invention is not limited to this. Further, for example, if the protrusion is made of plastic, vibration marks on the processed product can be eliminated. Further, the convex portion has a raised shape, for example, as shown in the figure,
It is preferable that the top surface has a flat shape and an inclined surface having an upward slope toward the center around the top surface. However, the shape is not limited to this, and various embodiments such as a bowl shape, a round shape, a round conical shape at the top, and the like are possible. It is. The number of vibration generators may be one or more.

[0006] As the above-mentioned vibration generator, a vibration motor is suitable. That is, according to the second aspect of the invention,
2. The microjoint separation device according to claim 1, wherein the vibration generator is a vibration motor. As this vibration motor, a low frequency vibration motor is exemplified. As a result, the above-described problem can be suitably solved, as well as the first aspect, and also contributes to downsizing of the apparatus.
Note that a vibration generator other than the vibration motor can be employed.
Also, the direction of vibration generation (the direction of rotation of the motor) can be set as appropriate.

There are various structures of the above-mentioned convex portion. For example, the invention according to claim 3 is the microjoint separation device according to claim 1 or 2, wherein the head of the convex portion has a flat or round shape. As a result, the object of claim 1 can be solved, and the separation efficiency of the product can be increased, and deformation of the processed product can be prevented. Specifically, it is preferable that the head has a flat surface and an inclined surface (which may be a curved surface or a flat surface) having an upward slope toward the center.

Since the above-mentioned vibration generator is a vibration source, a structure for effectively transmitting vibration and preventing the vibration from being transmitted to the table is required. As an example, the invention according to claim 4 is the microjoint separation apparatus according to any one of claims 1 to 3, wherein an elastic support member is provided on the top plate. The meaning of the elastic support member is that the top plate can effectively vibrate and that the vibration of the top plate is not transmitted to the table. Thus, the object of claim 1 can be solved, and vibrations can be effectively generated on the top plate.

There are various modes for those skilled in the art for the elastic support member described above. As an example, the invention according to claim 5 is the microjoint separation device according to claim 4, wherein the elastic support member is a vibration-proof rubber. This solves the same problem as the fourth aspect.

[0010] There are various modes for those skilled in the art as to the structure for attaching the elastic support member or the vibration generator to the top plate. As an example, the invention according to claim 6 is characterized in that the mounting portion of the elastic support member or the vibration generator is prevented from protruding from the surface of the top plate. It is. As a result, the same problem as in claim 1 is solved, and at the time of vibration,
The processed product can be smoothly placed on the top plate, and the processed product can be smoothly moved. Further, when the processed product has a convex portion, it can be prevented from being caught on the mounting portion, and there is an advantage that the processed product can be easily taken in and out.

Various structures can be adopted by those skilled in the art for the connection structure between the table and the cover. The invention according to claim 7 as an example thereof is characterized in that the cover is connected to one end side of the table and an extendable opening / closing mechanism having an open state holding function is provided. 3. The microjoint separation device according to item 1. This solves the same problem as the first aspect, and improves the efficiency of opening and closing the cover.
