DETAILED DESCRIPTION

(13) For purposes of description herein, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

(14) The reference number 100 (FIGS. 2A-3B) generally designates a bottle gripping assembly of the present invention. The bottle gripping assembly 100 of the present invention includes an improved base plate 102, a wear bushing 104 and an inner bushing 106. Moreover, while the top holder bracket 44 of the prior art is omitted, the grip arms 12a, the spring 36a and the bolts 52a remain the same. Since the grip arms 12a, the spring 36a and the bolts 52a are identical to the previously described grip arms 12, spring 36 and bolts 52, similar parts appearing in FIGS. 2A-3B are represented by the same, corresponding reference number, except for the suffix “a” in the numerals of FIGS. 2A-3B.

(15) In the illustrated example, the improved base plate 102 (FIGS. 3A-7) supports the grip arms 12a. The improved base plate 102 includes a rear wide portion 108 having a central actuator opening 110. The rear wide portion 108 of the base plate 102 is also shown as including a plurality of fastener opening 112 for accepting fasteners 116 therethrough for connecting the base plate 102 to a wheel 114 of the conveyor system (see FIG. 2B). The base plate 102 also includes a front narrow support portion 118 having a cutaway top area 120, with a step 122 between the rear wide portion 108 and the cutaway top area 120. The front narrow support portion 118 includes a pair of bolt openings 124 and counterbores 126 extending into the front narrow support portion 118 from the cutaway top area 120.

(16) The bottle gripping assembly 100 of the present invention includes several features for reducing wear with the grip arms 12a. For example, the improved base plate 102 includes a rectangular wear pad 130 located within the cutaway top area 120. The rectangular wear pad 130 includes a pair of bolt holes 132. The rectangular wear pad 130 has a top surface 134 that supports the grip arms 12a adjacent the bolts 52a. The wear pad 130 is formed of a material that provides support for the grip arms 12a, but also provides for sufficient friction to allow for the grip arms 12a to move under activation of the actuator 56. For example, the wear pad 130 can be made of polyether ether ketone (PEEK) or similar materials.

(17) In the illustrated example, the wear bushing 104 and the inner bushing 106 also reduce wear of the grip arms 12a. The inner bushing 106 includes a cylindrical portion 136 and a top flat portion 138. The cylindrical portion 136 extends through a bolt hole 25a in the middle area of the main section 24a of the grip arms 12a, through the bolt holes 132 of the wear pad 130 and into the counterbore 126 extending into the front narrow support portion 118 of the base plate 102 as shown in FIG. 4. The cylindrical portion 136 of the inner bushing 106 accepts the cylindrical portion 58a of the bolt 52 therethrough. The inner bushing 106 can be made of any material (e.g., a hard plastic or metal).

(18) The illustrated wear bushing 104 includes a cylindrical portion 150 and a top flat portion 152. The cylindrical portion 150 of the wear bushing 104 surrounds the cylindrical portion 136 of the inner bushing 106 and rests on the top surface 134 of the rectangular wear pad 130 as shown in FIG. 4. The top flat portion 152 of the wear bushing 104 is sandwiched between the top flat portion 138 of the inner bushing 106 and a top surface of the grip arm 12a also as shown in FIG. 4. The wear bushing 104 can be made of any hard material that reduces friction (e.g., a hard plastic).

(19) During use of the bottle gripping assembly 100 of the present invention, the actuator 56a can be actuated to move the grip arms 12a to grip the bottle 500 as outlined above, with the support lips 42a of the grip arms 12a supporting a top ring 502 of the bottle 500 located below a threaded cylinder 504 of the bottle 500 as shown in FIG. 2A. If the wear pad 130 and the wear bushing 104 become worn, the wear pad 130 and the wear bushing 104 can be replaced quickly and easily, thereby minimizing downtime of the bottling system. Moreover, replacing the wear pad 130 and the wear bushing 104 is less expensive than replacing the entire grip arms 12, top holder bracket 44 and base plate 14 of the prior art, thereby saving substantial money.

(20) Although particular preferred embodiments of the invention have been disclosed in detail for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the present invention.
