Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing adhered powder of a fragile substance which can efficiently remove the powder of the fragile substance without touching a product without manual operation.

[0002]

2. Description of the Related Art Generally, fragile products such as compression molded products before heat curing in powder metallurgy and injection molded products before heating are fragile and difficult to handle, so that powder adhering to them is removed. In some cases, removal is performed manually using a brush.

[0003]

The manual method, however, has problems that it takes time and labor, and that the product is destroyed during the removal to deteriorate the productivity.

[0004] An object of the present invention is to provide an apparatus capable of removing powder adhering to a fragile object without manual operation.

[0005]

Means for Solving the Problems The present inventor has conducted studies to solve the above problems and achieve the above object, and as a result,
The inventor has found that the object can be achieved by combining and using a means for transporting a fragile object and a means for blowing pressurized air, thereby completing the present invention. That is, the present invention provides a pair of arms that are vertically moved by a cylinder provided on a transfer cylinder, and that are arranged at intervals substantially equal to the outer diameter of a plurality of fragile objects in the longitudinal direction of the transfer cylinder. A pair of guide plates that are arranged in parallel with the transfer cylinder and guide the fragile object while holding the fragile object, and a pressurized air blowing nozzle that blows pressurized air to the fragile object from above between the pair of guide plates. The cylinder is lowered, the plurality of fragile objects are collectively pinched by the pair of arms, moved along the guide plate, and pressurized air is blown from the pressurized air blowing nozzle to the fragile objects. It is characterized by a device for removing adhered powder of fragile substances configured as described above.

In the present invention, as a means for moving the actuator and the arm up and down, for example, a cylinder using air pressure or hydraulic pressure can be used. Other components can also use the usual components. The fragile object is sandwiched between the two arms provided so as to interlock with the actuator, and the actuator is operated to move the arm in tandem, thereby transferring the fragile object and pressing the fragile object being transferred from above. By blowing air intermittently or continuously, powder adhering to the fragile object is blown off and removed.

However, the purpose can be achieved by providing the pressurized air blowing nozzle at at least one position in an arbitrary positional relationship or angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic view showing an embodiment of the present invention, partially cut away.

Reference numeral 1 denotes a substrate, and 2 denotes a transfer cylinder, which is fixed on the substrate 1 as an actuator. Reference numeral 3 denotes a pair of arms which are arranged on a plate 5 attached at intervals in the longitudinal direction of the transfer cylinder 2 and have an interval corresponding to the outer diameter of the fragile object to be clamped (four products in the illustrated embodiment). (Slightly larger than the outside diameter of the cylinder). A holding portion 6 is fixed so as to extend downward from each free end of the arm 3. And
The arm 3 can be moved up and down by operating each pneumatic cylinder 4.

Reference numeral 7 denotes an intermittent or continuous pressurized air blowing nozzle, which is provided on a support (not shown) provided on the substrate 1 so as to be at a position higher than the height of the arm 3 and outwardly. And connected to a source of pressurized air (not shown). On the other hand, reference numeral 8 denotes a pair of guide plates which are provided at an interval larger than the size of the holding portion 6 of the arm 3, and the product 9 is moved horizontally and vertically by the pressure of the pressurized air from the pressurized air blowing nozzle 7. It is held to prevent it from moving. 9 is a product,
Under the guide plate 8, it is placed on the guide rail 10 from the opposite side of the nozzle 7 for blowing the pressurized air and supplied in a line.

Since the apparatus according to the present invention is constructed as described above, the pair of arms 3 is lifted upward by the pneumatic cylinder 4, and the products 9 which are supplied and arranged in a line are divided into four pieces. Each of the arms 3 is moved down (hereinafter, referred to as one unit) so as to be collectively sandwiched between a pair of holding portions 6 vertically provided to the arm 3. Next, the transfer cylinder 2 is operated to move the plate 5 in the direction of the arrow, so that one unit of the product 9 is collectively transferred below the pressurized air blowing nozzle 7 by the pair of holding portions 6, and the pressurized air blow is performed. Pressurized air is intermittently or continuously blown downward from the nozzle 7 from above to below the product 9 to blow off and remove the powder attached to the product 9. This operation may be repeated several times as necessary. It is needless to say that this device can be a fully automatic device.

[0012]

As described above, according to the present invention, the means for transferring a fragile object and the means for blowing compressed air are used in combination, so that the fragile object is prevented from touching the fragile object. Adhered powder can be efficiently removed without manual operation, and a remarkable effect is recognized.
