Abstract
A suction cup removably attached to a housing lifts and moves an object. A venturi removably attached to the housing provides a vacuum effect to secure the suction cup to the object. The venturi includes a pair of opposing ears. When the venturi is inserted into a venturi hole of the housing, the ears compress a pin. When the venturi is rotated to an attached position, the ears do not contact the pin, and a spring biases the pin outwardly to secure the venturi to the housing. The pin is coupled to a button on the housing that can be slid to move the pin inwardly to allow rotation and removal of venturi.
Description
- This application is a divisional of U.S. application Ser. No. 10/460,847 filed Jun. 13, 2003, which claims priority to U.S. Provisional Application No. 60/389,489 filed Jun. 18, 2002.
- The present invention relates generally to a suction cup assembly including a housing having a venturi removably connected to the housing in a quick connect attachment and a suction cup to lift and move an object.
- Suction cups are commonly employed to lift and moves objects in an industrial application. Suction cups include a substantially conical body and are usually formed of a resilient material, such as plastic or rubber. When the body of the suction cup is placed against the object, a vacuum source expels air within a cavity formed by the conical body. As the air is expelled, the suction cup forms a tight seal on the object, allowing the object to be lifted and moved. The suction cup is usually mounted to a housing including a clamping stem. A robot arm of a tooling machine attached to the clamping stem moves the suction cup and the attached object.
- A suction cup occasionally needs to be replaced due to breakage, wear, or because a suction cup of a different shape or size is needed. Therefore, it is desirable that the suction cup is able to be changed quickly and easily.
- A venturi is commonly employed to provide the vacuum source that attaches the suction cup to the object. In one prior art suction cup assembly, the venturi is secured to the housing by a pair of bolts. Another prior art venturi is integrated in the housing. However, the venturi is internal, and it cannot be easily removed from the housing when cleaning is necessary.
- Additionally, in the prior art, the exhaust hole of the venturi is large, requiring a shuttle valve to block air expulsion from the exhaust hole.
- Hence, there is a need in the art for a suction cup assembly including a venturi that is removably connected to a housing.
- An industrial assembly includes a suction cup removably attached to a housing to lift and move an object. A venturi withdraws air inside the suction cup to form a vacuum on the object, allowing the object to be lifted.
- A bayonet coupling of the suction cup is received in a quick connect attachment in the housing. The bayonet coupling includes a pair of opposing ears. The bottom of the housing includes a base, a pair of opposing flanges and a pair of opposing openings between the flanges. A gap is defined between the flanges and the base.
- A pin is biased into one of the openings by a spring. When the ears of the bayonet coupling are positioned in the openings, an ear pushes on the pin and compress the spring. After the bayonet coupling is rotated 90°, the ears are located in the gaps under the flanges. The ear no longer compresses the pin, and the spring biases the pin into the opening, securing the suction cup to the housing. When the suction cup is to be removed from the housing, a slidable button coupled to the pin is slid to compress the spring and remove the pin from the opening. The suction cup can then be rotated 90° to align the ears of the bayonet coupling with the openings for removal of the suction cup from the housing.
- A venturi in combination with the vacuum source provides the vacuum effect to secure the suction cup to an object. The venturi is removably connected to the housing in a quick connect attachment. The venturi includes a pair of opposing ears. The housing includes a venturi hole that receives the venturi, a ledge surrounding the venturi hole, a pair of opposing flanges, and a pair of opposing openings between the flanges. A gap is defined between the flanges and the ledge.
- A pin is biased into one of the openings by a spring. When the ears of the venturi are positioned in the openings, an ear pushes on the pin and compress the spring. After the venturi is rotated 90°, the ears are located in the gaps under the flanges. The ear no longer compresses the pin, and the spring biases the pin into the opening, securing the venturi to the housing. When the venturi is to be removed from the housing, a slidable button coupled to the pin is slid to compress the spring and remove the pin from the opening. The venturi can then be rotated 90° to align the ears of the venturi with the opening for removal of the venturi from the housing.
- A blow off tube inserted into a blow off port provides air to release the suction cup from the object. The housing further includes a small exhaust hole that allows the air from the venturi or the blow off tube to escape from the housing. The venturi hole and the blow off port both communicate with the exhaust hole.
- These and other features of the present invention will be best understood from the following specification and drawings.

FIG. 1 illustrates selected portions of an exampleindustrial assembly 20 including ahousing 34 moveable by arobotic arm 24. Asuction cup 22 removably attached to thehousing 34 is employed to lift and move anobject 26. Apressurized air source 28, schematically shown, provides pressurized air that creates a vacuum inside a cavity of thesuction cup 22 to form a vacuum on theobject 26, allowing theobject 26 to be lifted and moved. Thevacuum source 28 is of a conventional type and is known in the art. - As shown in
FIGS. 2-5 , abayonet coupling 30 is fixed to thesuction cup 22. Thebayonet coupling 30 is received in a quick connect attachment in anopening 32 in thehousing 34 to allow thesuction cup 22 to be quickly and easily attached to and detached from thehousing 34. Thebayonet coupling 30, shown inFIG. 3 , includes a pair of opposingears 33. - The
pressurized air source 28 provides pressurized air through a connector hose 36 (FIG. 1 ). The pressurized air flows through a venturi (described below) which creates a vacuum. The air then flows through acentral passage 38 in thehousing 34, to secure thesuction cup 22 to theobject 26. - The
housing 34 further includes a mountingstem 40 shaped to be accommodated by a variety of clamps which are known in the art. The mountingstem 40 can be cylindrical, ball shaped, or any other shape. The mountingstem 40 is located so thathousing 34 can be clamped in any position relative to the clamp. Thesuction cup 22 can then be removed from thehousing 34 while maintaining the positioning of thehousing 34 relative to the clamp. -
FIG. 4 illustrates a perspective exploded bottom view of thehousing 34. Thehousing 34 includes abase 44, a pair of opposingflanges 42, and anopening 46 between each of theflanges 42 that is sized and shaped to receive anear 33 of thebayonet coupling 30. Agap 47 is defined between theflanges 42 and the base 44 such that the opposingears 33 of thebayonet coupling 30 can be inserted into theopenings 46 of thehousing 34 and twisted such that theears 33 are received into thegap 47 to secure thebayonet coupling 30 within thehousing 34. Aseal 35 is received in agroove 37 around thecentral passage 38 in thebase 44 of thehousing 34. When thebayonet coupling 30 is attached to the housing, theseal 35 provides sealing between thebayonet coupling 30 and thecentral passage 38. Theseal 35 can be an o-ring. - The
housing 34 further includes apinhole 50 that receives apin 52 and aspring 54. Thepin 52 includes arecess 56 that receives thespring 54 and a throughhole 58 perpendicular to the longitudinal axis A of thepin 52. Thespring 54 biases thepin 52 in the direction C and into one of theopenings 46 of thehousing 34. - As shown in
FIG. 5 , abutton 60 is slidably received in aslot 64 of thehousing 34 in directions B and C.A lock pin 62 moveable by thebutton 60 is received in the throughhole 58 of thepin 52. Thelock pin 62 couples thebutton 60 to thepin 52. When abutton 60 is slid in direction B against the bias of thespring 54, thelock pin 62 that is received in the throughhole 58 of thepin 52 removes thepin 52 from theopening 32. - Returning to
FIG. 4 , when attaching thesuction cup 22 to thehousing 34, thebayonet coupling 30 is positioned in theopening 32 such that thebayonet coupling 30 contacts thebase 44, and theears 33 are received in theopenings 46. In the non-attached position, theears 33 are non-aligned with theflanges 42. One of theears 34 of thebayonet coupling 30 presses thepin 52 in direction B and into thepinhole 50 such that thepin 52 does not enter theopening 46. Thebayonet coupling 30 is then rotated approximately ninety degrees until theears 33 of thebayonet coupling 30 align with theflanges 42. Thebayonet coupling 30 is then in the attached position. - A stop 65 positioned in the
gap 47 under one of theflanges 42 prevents further rotation of thebayonet coupling 30 once thebayonet coupling 30 is in the attached position. In the attached position, thebayonet coupling 30 no longer presses thepin 52, and thepin 52 is biased by thespring 54 in direction C into theopening 46, securing thebayonet coupling 30 to thehousing 32. Thebayonet coupling 30 cannot be rotated to the non-attached position because thepin 52 prevents rotation. - When the
suction cup 22 is to be removed from thehousing 34, thebutton 60 is slid in theslot 64 in direction B, and thelock pin 62 withdraws thepin 52 from theopening 32, compressing thespring 54. This allows for subsequent rotation of thebayonet coupling 30 ninety degrees to the non-attached position, moving theears 33 out of alignment with theflanges 42. Theears 33 are then aligned with theopening 46, and thesuction cup 22 can then be removed from thehousing 34. - A
venturi 66 removably received in aventuri hole 68 in thehousing 34 provides the vacuum effect. As shown inFIG. 6 , theventuri 66 includes afirst part 70 and asecond part 72. Thefirst part 70 includes avacuum hole 74 perpendicular to the length of theventuri 66 and a cylindrical passage 76 extending along the length of theventuri 66. Thesecond part 72 includes anend 78 having a pair of opposingears 80 and apassage 82 with a taperedportion 84. An arm 93 (FIG. 2 ) is connected to theend 78 of theventuri 66 to connect theconnector hose 36 of thevacuum source 28 to thearm 93. -
Seals grooves first part 70 and thesecond part 72, respectively, to provide further sealing between theventuri 66 and thehousing 34. Preferably, theseals venturi 66 operates in a conventional fashion as is known by those of ordinary skill in the art. - The
venturi 66 produces a venturi effect within thecentral passage 38 of thehousing 34 to secure thesuction cup 22 to theobject 26. Thepressurized air source 28 provides pressurized air that flows through theconnector hose 36, thearm 93, and then enters theend 78 of thefirst part 70 of theventuri 66. As the air passes through the taperedportion 84, a vacuum is produced within thevacuum hole 74 and thecentral passage 38 of thehousing 34 to secure thesuction cup 22 to theobject 26. - As shown in
FIGS. 4 and 7 , theventuri 66 is removably received in theventuri hole 68 in a quick connect attachment. Aledge 92 extends around the circumference of theventuri hole 68. Thehousing 34 includes a pair of opposingflanges 94 and anopening 96 between each of theflanges 94 that is sized and shaped to receive one of the opposingears 80 of theventuri 66. Agap 98 is defined between theledge 92 and theflanges 94. - A
pinhole 100 adjacent to theventuri hole 68 receives apin 102 and aspring 104. Thespring 104 is received in arecess 106 of thepin 102. Thepin 102 also includes a throughhole 108 that is perpendicular to the longitudinal axis D of thepin 102. Thespring 104 biases thepin 102 into one of theopening 96 of thehousing 34. - Returning to
FIG. 5 , alock pin 110 is slidable in aslot 112 on theupper surface 114 of thehousing 34. Thelock pin 110 is received in the throughhole 108 of the pin 102 (shown inFIG. 4 ) to couple thelock pin 110 to thepin 102. - When attaching the
venturi 66 to thehousing 34, thefirst part 70 of theventuri 66 is inserted in theventuri hole 68 until theears 80 are positioned in theopenings 96 and contact theledge 92. In the non-attached position, theears 80 are non-aligned withflanges 94. One of theears 80 forces thepin 102 in direction E and into thepinhole 100, compressing thespring 104 so that thepin 102 does not enter theopening 96. Theventuri 66 is then rotated approximately ninety degrees to the attached position such that theears 80 are aligned with theflanges 94 and non-aligned with theopenings 96. Theventuri 66 is then in the attached position. - As shown in
FIG. 7 , astop 115 positioned in thegap 98 under one of theflanges 94 prevents further rotation of theventuri 66 once theventuri 66 is in the attached position. In the attached position, theflanges 94 no longer contact thepin 102, and thepin 102 is biased by thespring 104 in direction F into theopening 96, securing theventuri 66 to thehousing 34. Theventuri 66 cannot be rotated to the non-attached position because thepin 102 prevents rotation. - To remove the
venturi 66 from thehousing 34, thelock pin 110 is moved in theslot 112 in direction E, removing thepin 102 from theopening 96 and compressing thespring 104. Theventuri 66 can then be rotated ninety degrees to move theears 80 out of alignment with theflanges 94 to the non-attached position. In the non-attached position, theears 80 are positioned in theopenings 96, and theventuri 66 can be removed from thehousing 34. - As shown in
FIG. 4 , a blow offtube 116 is inserted into a blow offport 118 of thehousing 34 to provide air through thecentral passage 38 of thehousing 34 to release thesuction cup 22 from theobject 26. Aconnector hose 120 connected to the blow offtube 116 is employed to provide the blow off air. - As shown in
FIGS. 5 and 8 , thehousing 34 further includes asmall exhaust hole 122 that allows the air from theventuri 66 or the blow offtube 116 to escape from thehousing 34. Theventuri hole 68 extends through thehousing 34 and communicates with theexhaust hole 122. The blow offport 118 is oriented proximate to theventuri hole 68 and also communicates with theexhaust hole 122. - Although a quick connect venturi has been illustrated and described, it is to be understood that other removably connected venturis can be employed. In one example, when the venturi is loaded into the venturi hole, a pivotal latch is pressed inwardly, compressing a spring under the latch. After the venturi is inserted into the venturi hole, the spring expands to move the latch outwardly, securing the venturi to the housing and the latch preventing removal of the venturi. The housing further includes a release that compresses the spring and releases and moves the latch to allow the venturi to be removed. Alternately, the venturi can be secured to the housing by a pin. The pin is inserted into a hole in the housing that aligns with a hole in the venturi. When the venturi is to be removed, the pin is removed, allowing removal of the venturi.
- There are several advantages to the suction cup assembly of the present invention. As the
housing 34 and theventuri 66 are combined, the number of parts and the height of thehousing 34 can be reduced. Additionally, as there are fewer parts, the cost is reduced. Theventuri 66 can also be easily removed for cleaning as theventuri 66 is attached in a quick connect attachment. Finally, because theexhaust hole 122 is small, a shuttle valve is not needed. - The foregoing description is exemplary of the principles of the invention. Many modifications and variations of the present invention are possible in light of the above teachings. The preferred embodiments of this invention have been disclosed, however, so that one of ordinary skill in the art would recognize that certain modifications would come within the scope of this invention.
