FIGS. 1-3 illustrate an embodiment of astock material feeder 110 or apparatus for feeding stock material to a machining device. The configuration of thestock material feeder 110 allows the stock material feeder to feed stock material along a feed axis illustrated as double-headed arrow 112. As such, the stock material feeder can feed the material into or draw the material out of a machining device, such as a CNC milling machine or a threading machine or other similar machining device. However, the type of machine to which material is being fed is merely for illustrative purposes and to provide a sense of the environment in which the device will operate and is to not be limiting on the scope of the invention. The feeding provided by the stock material feeder can be automated. - The stock material feeder includes an
electric motor 114 that operatively drives a plurality ofdrive wheels feed axis 112. The drive wheels are preferable formed of a rubber material. The rubber material may have varying hardness values depending on the stock material being fed. For example, if the stock material being fed is a very raw material having surface impurities or defects, the rubber material ofdrive wheels rubber drive wheels drive wheels drive wheels drive wheels - With primary reference to
FIG. 2 , thedrive wheels electric motor 114 by a plurality of gears 122-124.Gears shafts gear 124 is coupled to acoupling 130 that is connected to anoutput shaft 132 of the electric motor or output shaft of a gear train/transmission coupled to an output shaft of theelectric motor 114. Thedrive gear 124 does not rotate relative to coupling 130 ordrive shaft 132 such that rotation of thedrive shaft 132 causes thedrive gear 124 to similarly rotate. Additionally,drive gears shafts gears shafts -
Drive belt 134couples drive gears gear 124 such that driving ofdrive gear 124 causes the motor to also drivegears drive wheels shafts drive gears drive wheels drive shafts drive belt 134. Other gearing arrangements are contemplated to step up or step down drive rates. - The
drive shafts gears Gears shafts gears electric motor 114 to drive one or more adjacently positioned feed mechanisms, also known as “daisy chaining.”This is more fully described with regard toFIGS. 4 and 5 below. The adjacent feed mechanisms will have theirsimilar gears stock material feeder 110 by a belt or chain. As such, the electric motor of the primarystock material feeder 110 will drive the drive wheels of the additional material feeders as the two material feeders will be coupled by theirgears stock material feeder 110 typically will not include adrive motor 114. - With reference to
FIG. 1 , thestock material feeder 110 also includes aslave unit 144, which also may be referred to as a guide unit. Theslave unit 144 is spaced apart from thedrive unit 111 forming a stockmaterial feeding slot 146 therebetween through which the stock material is driven bydrive wheels axis 112. -
Slave unit 144 includes a second set ofwheels wheels axles axles bottom mounting plates mounting plates - The stock
material feed slot 146 is more particularly defined betweendrive wheels guide wheels stock material feeder 110 is laterally pinched or engaged between thedrive wheels guide wheels axis 112. As such, as thedrive wheels material feed slot 146 alongfeed axis 112, the opposed side of the stock material engages and is guided by theguide wheels guide wheels axles - The
drive unit 111 and theslave unit 144 are operably mounted to apositioning assembly 154 so as to position the two components relative to one another to adjust the width of the stockmaterial feed slot 146. The positioning assembly includes a pair ofcarriages guide rail 160 that is perpendicular to feedaxis 112. Thepositioning assembly 154 further includes adrive shaft 162 that has a first half of right-handed threads and a second half of left-handed threads that interact withdrive nuts user rotating handle 166, thenuts drive shaft 162. Thedrive nuts carriages carriages material feed slot 146 width is variable, and will be centered at the midpoint of the length of theguide rail 160. Driveshaft 162 could optionally be coupled for an electronic motor or other actuator for automatic or programmed adjustment of the width offeed slot 146. The motor actuator would typically replacehandle 166. - The
carriages guide rail 160. Thecarriages friction material bearings 170, 171 to prevent or reduce friction between thecarriages guide rail 160. Thedrive unit 111 andslave unit 144 preferably include part supports 174 that are positioned, at least in part, laterally inward from thedrive wheels guide wheels stock material feeder 110. In a preferred embodiment, the part supports 174, 176 are or include a ceramic support pad having top surface portion upon which the stock material slides as it is being fed by thestock material feeder 110. The top surface being orthogonal to the axes of rotation for the drive and guidewheels ceramic part support 174 reduces friction as well as reduces wear on the stock material as it is being fed bystock material feeder 110. The part supports 174, 176 have tapered ends to avoid catching ends of the stock material as it is fed throughfeed slot 146. Further, the part supports 174 are mounted onto support members. The support members, such as forslave unit 144, are attached to thebottom mounting plate 155. Further, the part supports 174 have a top surface that is proud of the top surface of the corresponding and adjacentbottom mounting plates 155. -
Guide rail 160 includes a plurality of slots andholes 176 that can be used to mount thepositioning assembly 154, and particularly theguide rail 160 to other structures.Guide rail 160 includes two rails for supporting thecarriages - In a preferred embodiment,
guide rail 160 is sufficiently long enough such that stockmaterial feed slot 146 can be at least 18 inches wide between thedrive wheels guide wheels handle 166 can be removed and replaced with a drive motor such that the positioning of thedrive unit 111 relative to theslave unit 144 can be automatically positioned. Further, when using automatic positioning of thedrive unit 111 relative toslave unit 144, other drive mechanisms such as opposed cylinders or lead or ball screws can be implemented. - Preferably, the stock material feeder includes a controller (not shown) that can be used to control the
electric motor 114 at variable speeds. This allows thestock material feeder 110 to increase or decrease the feed rate at which the stock material is being fed to the machining device rather than driving the stock material from a single point. - This ability to vary the feed rate further promotes the added benefit of being able to daisy-chain a plurality of additional feed devices to the primary
stock material feeder 110, such as through the use ofgears drive motor 114. There is no need to coordinate the acceleration or deceleration of a plurality of drive motors. Further, the control of a plurality of motors to maintain a constant speed between the different feed devices is eliminated. Additionally, the ability to daisy-chain a plurality of feed devices allows the devices to be tailored to the length of the stock material that is being fed. More particularly, the longer the stock material additional feed devices can be added to more properly engage and drive the stock material toward the machining device. - It should also be noted, that the
stock material feeder 110 can be used to draw material out of a machining device such that it is securely drawn from a machining device after it has been machined. As such, one stock material feeder can be positioned as an input feeder while a secondstock material feeder 110 can be used as an output feeder. - When a
stock material feeder 110 is used as an output feeder, thedrive wheels wheels -
FIG. 4 illustrates a further stockmaterial feed apparatus 200 that incorporates astock material feeder 110 from the previous embodiment and a second auxiliary stock material feeder 210 (also referred to as a slave stock material feeder or auxiliary feeder unit). As illustrated inFIG. 4 , the auxiliarystock material feeder 210 is mechanically coupled tostock material feeder 110 by a chain. The chain couplesgear 138 ofstock material feeder 110 to gear 136 of auxiliarystock material feeder 210 such that the actuation provided by the drive motor 114 (not numbered inFIG. 4 ) is transferred to the auxiliarystock material feeder 210. More particularly, as thedrive motor 114 operably drives drivewheels motor 114 will similarly drivegear 138. Driving ofgear 138 will then result in driving ofgear 136. As noted with regard toFIG. 1 , thedrive wheels stock material feeder 210 are coupled by a drive belt such that driving ofgear 136 will similarly drive both drivewheels stock material feeder 210. - With that being said, in the illustrated embodiment, the
stock material feeder 110 and the auxiliarystock material feeder 210 are substantially identical except that theauxiliary material feeder 210 does not include its own drive motor, as it relies ondrive motor 114 for its means of driving power. The coupling between thestock material feeder 110 and auxiliarystock material feeder 210 can be by way of chain, as illustrated, or alternatively by way of other coupling mechanisms such as a drive belt. The use of a chain or a drive belt allows for easy configuration of the material feed system by adjusting the lateral spacing between the variousstock material feeders - While the embodiment only illustrates a single auxiliary
stock material feeder 210, other embodiments can include a plurality ofauxiliary material feeders 210. Further, the plurality of auxiliary material feeders may be on either side ofstock material feeder 110. Further, a plurality ofauxiliary material feeders 210 may be linked together without any interveningstock material feeders 110 including adrive motor 114. - With reference to
FIG. 5 , a simplified top-view illustration of the material feed system ofFIG. 4 is illustrated. A piece of stock material, e.g. round rod stock, is being driven alongfeed axis 112 through stockmaterial feed slots 146 of both thestock material feeder 110 and the auxiliarystock material feeder 210. - Due to the daisy chained arrangement, the
stock material feeder 110 throughdrive wheels material 190 at a first location and drives thestock material 190 along the feed axis. Thematerial feed system 200 also simultaneously engages the first side of the piece ofmaterial 190 at a second location, remote from the first location, and simultaneously drives the piece of material along thefeed axis 112 at that second remote location. As used herein “remote location” shall refer to a location that is located at a separate stock material feeder (either a auxiliary or drive stock material feeder). - It should be noted that the
material feed system 200 actually contacts the side of thestock material 190 at a plurality of points at a single location. More particularly, the individualstock material feeders drive wheels stock material feeder - All references, including publications, patent applications, and patents cited herein are hereby incorporated by reference to the same extent as if each reference were individually and specifically indicated to be incorporated by reference and were set forth in its entirety herein.
