Container handling apparatus
A container handling apparatus configured to grip and support a container. The apparatus includes a support member configured to be coupled to a conveyor, and a one-piece retainer releasably coupled to the support member. The retainer is configured to engage a container and is preferably releasable from the support member without the use of tools.
This invention relates generally to material handling apparatuses, and more particularly to container handling apparatuses.
BACKGROUND OF THE INVENTIONThe transportation of containers within a beverage bottling facility is a critical factor in the overall performance and efficiency of the beverage bottling facility. Typically, containers arrive at the bottling facility from an off-site location, and are loaded into a transportation system that is configured to route the containers through the bottling facility. The transportation system includes multiple conveyors arranged to deliver the containers to one or more filling stations that fill the containers with a beverage. Depending on the configuration of the transportation system, the containers may be re-directed one or more times from one conveyor to another. Special transfer conveyors are utilized to transfer the containers between conveyors.
The transfer conveyors typically include one or more gripping mechanisms that grasp the neck portions of the containers when transferring the containers from one conveyor to another. Such a gripping mechanism may include a conventional “scissors-type” pincer mechanism that is operable via mechanical linkages driven by a cam arrangement. During operation of such a gripping mechanism, the opening of the pincer mechanism coincides with or occurs shortly before the neck portion of the container arrives in position to be grasped by the pincer mechanism. The cam arrangement actuates the mechanical linkage coupled to the pincer mechanism to control the opening and subsequent closing of the pincer mechanism. The transfer conveyor then re-directs the container toward another conveyor. Upon reaching the destination conveyor, the cam arrangement again actuates the mechanical linkage to release the container to the destination conveyor.
SUMMARY OF THE INVENTIONConventional gripping mechanisms, like the scissors-type pincer mechanism described above, may have some drawbacks. For example, the cam arrangement and mechanical linkages normally associated with actuating the gripping mechanisms are often complex, and as a result, are typically relatively expensive to manufacture. In addition to the complexity, the shear number of components involved with actuating the gripping mechanisms may impact the robustness of the design. Also, the complexity and shear number of components involved with the gripping mechanisms may require significant amounts of time for cleaning the gripping mechanisms. Further, conventional gripping mechanisms may be difficult to remove from the transfer conveyor because of the complexity introduced by the cam arrangement and mechanical linkages responsible for actuating the gripping mechanisms. As a result, changing-out or replacing a damaged or non-functional gripping mechanism may require significant amounts of down-time.
The present invention provides a container handling apparatus configured to grip and support a container. The apparatus includes a support member configured to be coupled to a conveyor, and a one-piece retainer releasably coupled to the support member. The retainer is configured to engage a container.
In another aspect, the present invention provides the retainer having a first arm portion, a second arm portion, and a base portion interconnecting the first and second arm portions. Each of the arm portions includes a distal end, and the distal ends of the respective arm portions are spaced and configured to accept entry of the container such that the arm portions deflect away from one another as the container enters between the distal ends. Each of the arm portions also includes an arcuate portion to secure the container between the respective arcuate portions of the first and second arm portions.
In yet another aspect, the present invention provides a mounting member configured for releasably engaging the support member to couple the support member to the conveyor. The retainer is releasable from the support member only when the support member is disengaged from the mounting member. The support member is releasable from the mounting member without the use of tools, and the retainer is releasable from the support member without the use of tools.
The present invention also provides a method of re-conditioning a container handling apparatus including a support member configured to be coupled to a conveyor. The method includes coupling a first one-piece retainer to the support member, engaging and releasing a first container with the first retainer, uncoupling the first retainer from the support member, coupling a second one-piece retainer to the support member, and engaging and releasing a second container with the second retainer.
Further, the present invention provides a conveyor assembly including a conveyor, and a plurality of container handling assemblies coupled to the conveyor. Each of the container handling assemblies includes a mounting member coupled to the conveyor, a support member releasably engaged to the mounting member, and a one-piece retainer releasably coupled to the support member. The retainer includes a first arm portion, a second arm portion, and a base portion interconnecting the first and second arm portions such that a container can be engaged and retained by the first and second arm portions. The retainer can be uncoupled from the support member without the use of tools upon disengagement of the support member from the mounting member.
Other features and aspects of the present invention will become apparent to those skilled in the art upon review of the following detailed description, claims and drawings.
BRIEF DESCRIPTION OF THE DRAWINGSIn the drawings, wherein like reference numerals indicate like parts:
Before any features of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other constructions and of being practiced or being carried out in various ways. Also, it is understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including” and “comprising” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.
DETAILED DESCRIPTION
In the illustrated construction of
The bottle 18 may be made of a polyethyleneterephthalate (PET) plastic material, or any other suitable plastic material. However, the bottle 18 may also be made from a different material, such as glass. Further, the container handling apparatus 10 may be configured to handle other items having a narrowed portion similar to the neck portion 22 of the bottle 18.
As shown in
The material properties of the retainer 38 determine the extent of the inward bias, or the resilience of the retainer 38. In the illustrated construction, the retainer 38 is made from a spring steel material (e.g., 302 STST). However, the retainer 38 may be made from other materials that are capable of providing a sufficient inward bias or resiliency of the first and second arm portions 42, 46 for a particular bottle-handling application. In addition, the retainer 38 is shown (see
As shown in
With continued reference to
After the neck portion 22 initially passes the respective distal ends 54 of the first and second arm portions 42, 46, the forward portions 62 cause the first and second arm portions 42, 46 to deflect away from each another in response to the insertion of the neck portion 22 into the retainer 38. In the illustrated construction of
In addition, a clearance dimension D1between the respective forward portions 62 of about 66% of the diameter of the neck portion 22 exists to allow the neck portion 22 to be engaged by the retainer 38 with an amount of resistance to engagement. The clearance dimension D1is also sized to provide an amount of resistance to disengaging or removing the bottle 18 from the retainer 38, such that unintentional disengagement or removal of the bottle 18 from the retainer 38 is substantially prevented. The clearance dimension D1may be varied to affect the retainer's resistance to engagement or disengagement with the bottle 18. The clearance dimension D1may be as small as about 63% of the diameter of the neck portion 22, or as large as about 71% of the diameter of the neck portion 22.
As the neck portion 22 passes the respective forward portions 62 of the first and second arm portions 42, 46, the inward bias of the first and second arm portions 42, 46 causes them to return to their undeflected positions, thereby securing the neck portion 22 between the respective middle portions 66. In the illustrated construction of
The first and second arm portions 42, 46 also each include rear portions 70 adjacent the respective middle portions 66. In the illustrated construction of
With continued reference to
In the illustrated construction, the retainer 38 is symmetrical about a longitudinal axis 82 extending in a direction normal to the base portion 50, such that the first and second arm portions 42, 46 are substantially identical. However, in other constructions of the retainer 38, the retainer 38 may be asymmetrical about the longitudinal axis 82, such that the distal ends 54 or the arcuate portions 58 of the respective first and second arm portions 42, 46 are configured and/or shaped differently. For example, the first arm portion 42 may define an arcuate portion shaped to grasp more of the neck portion 22 than the arcuate portion of the second arm portion 46.
With reference to
The projections 86 are spaced an appropriate distance apart so the retainer 38 may be releasably coupled thereto. In addition, the projections 86 are spaced an appropriate distance apart to act as a fulcrum to the movement of the first and second arm portions 42, 46 in a direction substantially normal to the longitudinal axis 82. As shown in
The support member 34 also defines a recess 94 to receive a portion of the bottle 18. More particularly, the recess 94 is substantially defined by a radius sized to receive the neck portion 22 of the bottle 18. As shown in
With reference to
With continued reference to
The mounting member 102 further includes a slot 122 sized to receive therein the body 88 of the support member 34. In the illustrated construction, the rear edge of the support member 34 is received in the slot 122. Further, the mounting member 102 includes a button 126 upwardly extending through an aperture 130 in the mounting member 102. The button 126 is biased upwardly by a compression spring 134, which is maintained in position by a perch 138 coupled to the fixture 106. In its extended position, the button 126 is engageable with the support member 34 via an aperture 142 in the support member 34 (see
When the support member 34 is secured to the mounting member 102 by the button 126, the retainer 38 is fully secured to or captured by the support member 34, since the intermediate portions 74 are abutted against the projections 86 and the base portion 50 is abutted against the mounting member 102. The abutment of the base portion 50 with the mounting member 102 biases the intermediate portions 74 against the projections 86. The abutment further prevents rotation of the retainer 38 with respect to the support member 34 and the mounting member 102. As a result, the retainer 38 is prevented from being removed from the support member 34 while the support member 34 is coupled to the mounting member 102.
With reference to
Such reconditioning and/or reconfiguring processes are performed in substantially the same manner and without the use of tools. Since the retainer 38 is secured in place by both the support member 34 and the mounting member 102, the support member 34 must be disengaged and removed from the mounting member 102 before the retainer 38 is disengaged from the support member 34. More particularly, an operator would first depress the button 126 so that the button 126 disengages the aperture 142 in the support member 34. The operator may then disengage the support member 34 from the slot 122 in the mounting member 102.
After the support member 34 is cleared from the mounting member 102, the operator may move the retainer 38 out of abutment with the projections 86. To accomplish this, the operator grasps the base portion 50 of the retainer 38 and pulls it in the direction of the longitudinal axis 82 to move the retainer 38, specifically the intermediate portions 74, out of abutment with the projections 86. Alternatively, the operator can squeeze the distal ends 54 together and push the retainer 38 toward the projections 86.
To re-insert another retainer 38, the operator aligns the retainer 38 with the grooves 90 in the projections 86 and pushes the retainer 38 (by grasping the base portion 50, for example) such that the distal ends 54 and the arcuate portions 58 pass between the projections 86 before the intermediate portions 74 come into abutment with the projections 86. Next, the support member 34 is coupled to the mounting member 102. The operator depresses the button 126, and inserts the support member 34 into the slot 122 of the mounting member 102 until the button 126 snaps into and engages the aperture 142 in the support member 34. As the button 126 snaps into the aperture 142, the base portion 50 of the retainer 38 comes into abutment with the mounting member 102 to fully secure the retainer 38 in place on the support member 34.
When reconfiguring the container handling apparatuses 10 to accommodate different size bottles 18, a first retainer 38 having a first size is removed and replaced by a second retainer 38 having a second size. However, in addition to the retainer 38, a first support member 34 may also be replaced by a second support member 34 having a recess 94 of a different size from the recess 94 of the first support member 34.
The projections 86′ are configured much closer to each other on the support member 34′ as compared to the projections 86 on the support member 34 of
As shown in
From the location of the middle portions 66′ indicated by gap G1, the remaining parts of the middle portions 66′, the forward portions 62′, and the distal ends 54′ are angled upwardly away from the body 88′ of the support member 34′ to facilitate entry of the collar 30 between the support member 34′ and the retainer 38′. Upon insertion of the neck portion 22 into the recess 94′ of the support member 34′ and into the arcuate portions 58′ of the retainer 38′, the retainer 38′ is upwardly deflected and biased downwardly against the collar 30 at the press point P (see
With reference to
The retainer 38″ may be coupled and de-coupled with respect to the support member 34 or 34′ using any of the above or other procedures, depending upon how the retainer 38″ is configured to be engaged with the projections 86 or 86′ of the support member 34 or 34′.
