DETAILED DESCRIPTION

(9) The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

(10) Referring to FIGS. 1A and 1B, a transport assembly 100 of the present disclosure is operable to transport one or more articles 102 (e.g., fixtures, parts, etc) to, for example, a machine. In one form, the transport assembly 100 includes a lift cart 104 and one or more carriers 106 (e.g., 106.sub.1 to 106.sub.5 in figures) for supporting the article 102 to be transferred.

(11) The lift cart 102 includes a body 110, a plurality of wheels 112 attached to the underside of the body 110, and a table 114 disposed on the body 110. The body 110 includes a height adjustment mechanism for lifting and supporting the table 114. For example, in one form, the body 110 is configured as a scissor cart lift that includes a hydraulic pump or an electric motor for adjusting the height of the table 114. The present disclosure is also applicable to other height adjustable cart and should not be limited to scissor cart lifts.

(12) The lift cart 102 is configurable in various suitable ways based on the articles 102 and the carriers 106 being transported. Referring to FIG. 2, in one form, the lift cart 102 includes a railing 116 disposed along a periphery of the table 114 to prevent the carriers 106 from falling off the cart 104. The railing 116 further defines an opening 118 through which the article 102 are transferred to and from the cart 102. In another form, to accommodate articles that may have fluid, the lift cart 104 has a channel 120 defined between the table 114 and the railing 116 for collecting fluid dripping from the article 102, thereby preventing fluid from collecting on the surface of the table 114.

(13) Referring to FIGS. 3A and 3B, the carriers 106, which may also be referred to as skateboards, include a panel 124 and multiple wheels 126 attached to the underside of the panel 124. The carriers 106 are operable to slidingly move along the table 114. The carriers 106 can be configured in various suitable ways for holding the article 102, and thus, can be customized for a specific application. For example, in one form, the carriers 106 are configured to receive cardanic fixtures for honing machine, and include a slot 128 defined along a surface of the panel 124 to accommodate the fixture.

(14) To prevent unwanted movement of the carriers 106, the assembly 100 further includes a carrier lock for fastening and unfastening the carriers 106 to the table 114. Referring to FIG. 4, in one form, a carrier lock 130 includes a stake member 132 having a handle 134 and one or more posts 136 extending from the handle 134. The table 114 and the carrier 106 are configured to receive the stake member 132. For example, in one form, the table 114 may define a plurality of apertures 138 or ports, and each of the carriers 106 defines holes 140 (FIG. 3A) extending through the panel 124. The apertures 138 and the holes 140 are part of the carrier lock 130. That is, to fasten the carrier 106 to the table 114, the posts 136 of the stake member 132 extend through the holes 140 of the carriers 106 and one or more apertures 138 of the table 114. The stake member 132 can be removed and installed by way of the handle 134. While one form of a lock is illustrated, other lock mechanism may also be used and are within the scope of the present disclosure. For example, the lock may be a brake member disposed at the wheels 126 of the carriers 106, and operable to engage and disengage with the wheels to prevent the wheels from moving.

(15) To control the movement of the lift cart 104, the article transport assembly 100 includes one or more cart locks that are operable to hold the position of the cart 104. With continuing reference to FIGS. 1A and 2, in one form, the cart lock is provided as brakes 150 disposed with one or more wheels of the cart, and operable to engage and disengage with the wheels. In another form, the cart lock is provided as a slot member 152 that couples the cart lift 104 to the machine receiving the articles 102. For example, the slot member 152 includes a panel 154 that defines a slot 156 that engages with a sidewall portion 158 of a staging area 160 of the machine. In one form, to couple to the sidewall portion 158, the height of table 114 is adjusted to be above the sidewall portion 158, as indicated by position A in FIG. 1A and then lowered such that the sidewall portion 158 rests within the slot 156 of the slot member 152, as indicated by position B in FIG. 1A. The sidewall portion 158 can be located at other suitable locations of the machine and should not be limited to the staging area. The cart lift 104 can include other suitable cart locks that are operable to restrict the movement of the cart lift 104, and should not be limited to locks described herein.

(16) An exemplary application of the transport assembly 100 is described herein. The assembly is configured to transport new cardanic fixtures to a honing machine and exchange the new fixtures with worn fixtures disposed in the machine. In one form, the transport assembly 100 is configured to include multiple carriers 106.sub.1 to 106.sub.5 with at least one empty carrier (i.e., a first carrier 106.sub.1). The transport assembly 100 is moved and secured to the machine. For example, the table 114 having the slot member 152 disposed along the underside of the table 114 is positioned next to a counter 162 (FIG. 1B) of the staging area 160 of the honing machine. The height of the table 114 is increased and the position of the slot member 152 is aligned to be over the sidewall member 158. The slot member 152 is then lowered to the sidewall member 158, such that the edge of the sidewall member 158 is positioned in the slot 156. In addition to or in lieu of coupling the transport assembly 100 to the machine, the position of the transport assembly 100 may be locked by engaging the brake 150 of the lift cart 104.

(17) To exchange the fixtures from the lift cart 104 with the worn fixtures in the machine, the empty carrier 106.sub.1 (FIG. 1B) is decoupled from the table 114 and is slidingly moved or, in other words, rolled towards the opening 118 defined by the railing 116, and then coupled to the table 114 via the carrier lock 130. The worn fixture, which is resting on, for example, the counter of the staging are next to the table 114 is then slid onto the surface of the carrier 106.sub.1. The carrier 106.sub.1 is then decoupled from the table 114 and moved to an empty position on the table 114 and then coupled to the table. A carrier having a new fixture (i.e., a second carrier 106.sub.2) is then decoupled from the table 114 and then moved towards the opening 118. The new fixture is slid onto the counter 162, and then fed into the machine.

(18) Another worn fixture is then removed from the machine and placed on the counter 162. From the counter 162, the worn fixture is moved onto the second carrier 106.sub.2, and the second carrier 106.sub.2 is then shifted to another location on the table 114, where it is coupled to the table 114 using the carrier lock 130. In one form, one or more of the carriers 106 are slidingly moved along the table 114 to move the second carrier 106.sub.2 to allow another carrier 106 having a new fixture to move to the docking location for unloading a new fixture and receiving a worn fixture. The carriers 106 are shifted one by one towards the opening to unload a new fixture and receive a worn fixture until the machine is equipped with all new fixtures.

(19) By having the carriers, an operator can transfer articles from the cart to the machine by sliding the articles along the table to the opening instead of lifting the article from the cart, thereby limiting the physical operation performed by the operator. In addition, one cart can be utilized for transporting new articles and receiving worn articles, thus reducing the complexity of the operation and reducing the time required to exchange the components.

(20) The description of the disclosure is merely exemplary in nature and, thus, variations that do not depart from the substance of the disclosure are intended to be within the scope of the disclosure. Such variations are not to be regarded as a departure from the spirit and scope of the disclosure.
