Description
1039~Z
~ he present invention relates to a robot assembly for transferring articles or materials from one position to another position.
Apparatus for transferring articles from one location to another are known as robots, and are capable of transferring articles between two end positions, and can move vertically and horizontally as well as performing rotational movements. ~urthermore, the drive systems hereto-fore used in robot constructions are preferably pneumatic or hydraulic. In addition, electric motors have often been used. Most all of these systems are both complicated and expensive to manufac~ure. -It is an object of the present invention to provide a robot assembly which is relatively simple in con-struction yet is reliably effective for the purposes intended.
Another object of the present invention is toprovide transfer units which are given a swinging motion by the robot drive unit. ~his swinging motion is inter-rupted by retaining means in the form of magnetic members when the transfer unit is in their respective end positions.
It is a further object of the present invention to utilize drive members in the form of spring means, which in a neutral position between the end positions, do not exert any force on the transfer unit but in the end positions act on the unit by generally equal but oppositely directed forces.
The invention will now be more fully described with reference to the accompanying drawings, in which:

FIG. 1 is a side elevational view, partly in section, of the robot apparatus for transfe ring articles showing the drive system together with cooperating structure for performing both vertical longitudinal movement ae well as horizontal rotary movement in accordance with the teachings of the present invention.
FIG. 2 is a top plan view of the robot apparatus shown in FIG. 1.
FIG. 3 is a sectional view taken along the line III~
of FIG. 1 and FIG. 4 is a sectional view of a detail of construction being a part of the guideunit for vertically longitudina' movement.
Referring to FIG. 1, the robot apparatus,discloses three modules which co-act to perform different operations.
~he unit referred to generally by the reference numeral 10 is a vertical movement unit. The rotary movement unit is referred to generally by the reference numeral 11 while the gripper device 13 is shown mounted on the elongated arm 12.
lhere is provided drive systems for both the vertical movement unit 10 and the rotary movement unit 11. Furthermore, a selected drive system can be utilized to move the arm 12 in a direction parallel to its length. A drive system can also be used to operate a unit for tilting the apparatus at an angle to the surface it rests upon. ~his tilting unit may be mounted between the vertical movement unit and the rotary movement unit.
As seen in ~IG. 1, the vertical movement unit 10 is mounted on a base plate 14, the latter supporting a guide unit 15 comprising a rod 17 attached to the base plate 14 by means of a screw 16. The guide unit 15 is further pro-vided with four elongated grooves 18 for seating ball bearings 19. The balls 19 are maintained into engagement with the grooves 18 by means of square bushings 21 having grooves 20 for receiving the balls. The bushing 21 is attached to plates 23 by means of screws 22 (FIG.4).
Furthermore, the plates 23 are attached by means of screws 24 to a mounting plate 25, which, as shown in ~IG. 1, supports the rotary movement unit 11. The plates 23 together with the mounting plate 25 forms the mobile part of the vertical movement unit 10. Referring to ~IG. 4, it will ~ .
15: be seen that the upper end of the rod 17 supports a stop - ::
plate 27 which is secured thereto by means of a screw 26, -and which prevents the balls 19 from escaping entrapment in the grooves 18.
An helical spring 28 is clamped between the base plate 14 and the mounting plate 25. As seen in ~IG. 1, the upper end of spring 28 is secured to a pin 29 which, in turn, is attached to the mounting plate 25. The opposite or bottom end of spring 28 is secured to the disc 30 in which .
an adjustment screw 31 is threaded. A wheel 32 is connected to the adjustment screw and can be rotated to the desired position in order to set the adjustment screw 31. :Eurther-more, as seen in ~IG. 1, the bottom end of the adjustment screw is ~itted into a hole in the base plate 14 and rests against the bottom of the hole. Ihus, when the adjustment screw 31 is turned by means of the wheel 32 the disc 30 is moved either upwardly or downwardly whereby the neutral position can be set about which the vertical swinging move-5 ment occurs. I-t should be noted that when setting the neutral position, the weight of the parts involved in the vertical movement has to be considered. Ihereafter, the disc 30 can be locked in the preselected set position by means of a lock nut 33.
As seen in FIGS. 1 and 3 rails 34 and 35 are mounted on the base plate 14. Each of the rails supports a respective electromagnet 36 or 37 which are attached thereto by means of screws 38 and 39 which are movable to selected positions in the elongated holes or slots 40 and 41 in the 15 support rails 34 and 35. Ihis arrangement provides the adjustability of the positions of the electromagnets 36 and 37 in the apparatus. ~he electromagnets 36 and 37 are removably attached by screws 42 and 43 to corresponding U-shaped brackets 44 and 45 in which the screws 38 and 39 engage.
Referring to FIG. 1, the angle brackets 46 and 47 are sh~n with permanent magnets 48 and 49 secured thereto by means of screws 50 and 51 which are disposed on the plates 23 fastened to the mounting plate 25.
lhe base plate 52 for the rotary movement unit 11 is secured to the mounting plate 25 of the vertical movement unit 10. ~he base plate 52 is further provided with an upstanding tube 53 in which a shaft 54 is journalled by means of ball bearings 55. A sleeve 56 fits over the top of shaft 54 and supports the arm 12 which is fitted to the upper end of said shaft. lhe arm can then pivot between the end positions determined by the electromagnets 57 and 58 supported by holders 59 and 60 which are removably clamped on the tube 53. ~his arrangement is particularly seen in FIG 2. lhe positions of the electromagnets 57 and 58 can be readily altered by turning the corresponding holder 59 ~ -or 60, respectively. Furthermore, it should be observed that the permanent magnets73 and 74 are mounted on a holder 61 which is clamped on the shaft 54 and co-acts with said electromagnets.
In order to operate the arm 12 and, as seen in FIG. 1, a coiled spring 62 of the clockwork type is clamped 15 between the holder 61 and the holder 63 which are, in turn, ~-clamped on the tube 53. lhe neutral position can be set by turning the holder 63 about which the arm 12 makes a swinging movement. -Referring to FIG. 1, it will be noted that the -gripper device 13 is shown secured to one end of the arm 12 and includes a stationary arm 64, as well as a movable arm 65 journalled in the StatiGnary arm 64 and co-acting therewith in order to grasp an article 66. An angle bracket 67 is mounted on the other end of the arm 12 with a sleeve 68 -attached thereto. lhe sleeve 68 mounts an electromagnet 69 h~ving a movable armature 70 to which one end of a wire 71 is fastened. ~he other end of the wire 71 is fastened to a . .
:-, movable gripper arm 65 and acts on the gripper arm against the force of spring 72. '~he spring 72 is mounted on the one end on the movable arm 65 and at the other end on the stationary arm 64.
Ihe operation of the robot apparatus is as follows:
Assuming that the article 66 has just been grasped by the gripper device 13, the transfer units then assume the position shown in FIG. 1. In this condition the vertical movement unit 10 moves a rotary movement unit 11 with the arm 12, and the article 66 to the other end position, as determined by the electromagnet 37. lhereafter, the rotary unit 11 turns 180 from the position shown in FIG. 2 to the end position determined by the electromagnet 58. Finally, the gripper device 13 delivers the article 66 to a receiving station (not shown). It should be noted that all electromagnets shown in the present apparatus are connected to a central control unit (not shown) from which the required electrical current is supplied.
Current is supplied to the electromagnet 36 to excite the same and generate a repulsion field of opposite direction to the magnetic field emanating from the perman-~t magnet 48. Simultaneously, the electromagnet 37 is excited by means of the application of electrical current thereto and thereby generate an attraction field in the same direction as the magnetic field emanating from the perman-ent rnagnet 49. '~he vertical movement unit 10 is released to move toward the upper end position and an upwardly _ ~ _ 1~)39322 directed swinging motion is initiated under the action of the spring 28. In the initial stage of movement, this motion receives an additional force by the relative magnet repulsion of the electromagnet 36 and a permanent/48. ~on-sequently, the spring 28 is capable of forcing the mobilepart of the vertical movement unit 10 to a location near the upper end position thereof. The mobile part is then moved to the upper end position under the action of the :
relative attracting forces of the electromagnet 37 and the permanent magnet 49. : -When the vertical movement unit 10 has performed its up1~ard movement the electromagnet 57 is excited by the application of current thereto to generate a repulsion field counteracting the field generated by the permanent magnet 73. Simultaneously therewith, the electromagnet 58 is excited to generate an attraction field co-acting with the magnetic field generated by the permanent magnet 74. As a result of the foregoing functions the arm 12 is released and a swinging motion toward the opposite end position is ; --started under the action of the spring 62. As is the case in a vertical movement, a pulling force is added to the -spring 62 in the initial stage, the result being the rela-magnet tive repulsion of the electromagnet 57 and the permanent/73.
Moreover, the spring 62 moves the a~m 12 to a position in .
which the permanent magnet is so close to the electromagnet - ..
58 that it is engaged by the attractive force generated by the electromagnet and moved by this force to abut the electro-rr~gnet.
~1hus, ~hen the rotary unit 11 has accomplished its _ g _ prescribed movement, the electromagnet 69 is acted upon ana the gripper device delivers the article 66 to a pre-determined location.
Ihe movement of the gripper device 13 back to its starting position shown in FIG. 1 occurs according to a similar pattern as that described hereinabove. However, the difference is that the electromagnets which, according to the foregoing description, have been excited to gener-ate a repulsion field are instead excited to generate an attraction field. Moreover, since the magnetic repulsion fields are active only in the initial stage of the swinging motion, the electric current to the relevant electromagnet can be disconnected during the continued movement in order to save energy.
It should be apparent that the robot transfer assembly as set forth hereinabove is a relatively simple construction but functions as a reliably operating apparatus.
l~hile certain embodiments of my invention are herein illustrated and described, it will be understood that changes may be made in the construction and arrange-ment of elements without departing from the spirit or scope of my invention. Iherefore, without limitation in this respect, the invention is defined by the following claims.
