(Granted under the act of March 3, 1883, as amended April 30, 1928; 3-70 0. G. 757) 1 7 Claims.
The invention described herein may be manuf factured' and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.
This invention relates to means for positioning objects.
An object of this invention is to provide apparatus for quickly orienting bodies in a given direction from a condition in which the bodies are oriented in random directions with respect to themselves and with respect to said given direction.
Another object of this invention is to provide apparatus for orienting the position of bodies; simultaneously, some of the bodies undergo a separation as they are oriented.
In particular, thisinvention has application and relates to means for the separation and racking of small cups or tubes having one open end and oneclosed end, or one open end and one partially closed end; this invention may also be applied in the separation and racking of bodies not containing hollow portions.
The specific nature of the invention as well as other objects and advantages thereof will clearly appear from a description of a preferred embodiment as shown in the accompanying drawings in which:
Figure 1 is a plan view of apparatus embodying a preferred form of my-invention, but with the racking tray removed.
Figure 2 is a plan view of the racking tray surface which is placed in adjacent relationship to the surfac shown in Figure 1.
Figure 3 is a plan view of the pin plate II] which lies behind the guide block II shown in Figure 1 and which is normally permanently assembled thereto by fastening means similar to screws 20.
Figure 4 is a side view of one of the bullet shaped pins which is normally held on the pin plate Ill in semi-fixed relationship as by means of a press fit between pin shank I 4a and pin plate hold Illa.
Figure 5 is a sectional view taken substantially on corresponding lines 55 of Figure 1 but with the racking tray I2 of Figure 2 mounted in position.
Figure 6 is a sectional view taken substantially on corresponding lines 6-6 of Figure 1 but with the racking tray of Figure 2 mounted in position.
Figure 7 is a sectional view taken substantially on line 'I-'l of Figure 1 but with the racking tray of Figure 2 mounted in position; the flap I5 is shown in dotted lines in its other extreme position.
Figure 8 is a perspective view partly broken away of one of the plurality of objects which may be separated and oriented by using the apparatus of Figures 1-7.
Figure 9 is a, perspective view of a solid cylindrical object which may also be separated and oriented by using the apparatus of Figures 1-7 provided the pins I4 are not assembled on the pin plate Ill.
2 guide block II so as to cooperate With flange elements I3a, I32), I in inclosing a predetermined area corresponding to the area of racking tray I2.
The pin plate I0 is joined to guide block II by fastening means similar to screws 20 and flange elements I3a, I3b, I3c are joined to guide block I 5 by fastening means similar to screws 2 I.
Flap I5 is mounted on the guide block I I by means of a pair of hinges 22, 23. The hinges 22, 23 may be of any of the well known types as long as they allow the flap I5 to assume the two extreme positions shown in Figure 7. The particular hinge 22 shown herein and which is a duplicate of hinge 23 is of the type which comprises two parts 22a, 22b interlinked by means of a common cylindrical pin 24.
The pin plate ID has pins I4 shown in Figure 4 fastened thereto by press fitting when objects of the type shown in Figure 8 are to be separated and/or oriented; pins I4 are not mounted on pin plate I0 when objects of the type shown in Figure 9 are to be separated and/or oriented.
It is noted that guide block II has a plurality of hollow cylindrical portions I Ia therein having a diameter or opening correspondingly greater than the dimensions of the objects, which are to be separated and/or oriented. The hollow portions Ila are preferably joined by a flared portion II b which serves as a guide for movement of objects to be separated and/or oriented into the hollow portions Ila.
It is also noted that pin I4 has a nose shaped like that of a bullet with a minute radius provided for the point and an intermediate curvature starting down four fifths of the diameter of the pin, the radius of said curvature being three eighths larger than the diameter of pin I4. When the pin I4 is assembled on the pin plate I 0 it is noted that the extreme end of the pin nose extends a small distance into the space defined by the guide block flared section I lb.
Objects are separated and/or oriented by the following expedient. Initially a bulk lot of components or objects are placed on the upper face of the guide block with the flap I held up in the vertical position shown in full lines in Figure 7 so that the components or objects may be brushed back and forth over the upper guide block face within the inclosed area defined by flange l3 and flap i5. In the back and forth motion of the components or objects over the guide block face eventually the open end of a hollow object or component finds its way over the nose of pin l4 and then quickly falls into the hollow portion delined by guide block portion Illa. The excess objects or components are then brushed off the block guide upper face very conveniently by brushing them in the direction of flap l5 but with the flap in the downward position shown in dotted lines in Figure '7. Racking tray l2 having indentations l2a in one face thereof in exact geometric pattern as th hollow guide block portions Ha is then placed on the guide block upper face with indentations l2a facing downward; the racking plate is automatically centered on the guide block when flap I5 is raised to its upper position shown in full lines in Figure '7 and immediately thereafter the complete assembly is turned over so that the objects to be separated and/or oriented rest upon the racking tray l2 in the racking tray indentations IZa. The guide block is then separated from the racking tray l2 by raising the guide block ll upward with the racking tray I2 conveniently resting upon a table (not shown) or other suitable support.
