- a support side frame comprises horizontal members 20 and 21 operatively connected to upright member 22 .
- the members 11 through 22 are connected by suitable means such as welding. It is of course understood that other suitable constructions of a frame may be utilized. However, as will be discussed more fully hereafter, it is noted that there is not an operating side frame which would effect access to the operating side of the dispenser 10 .
- a drive assembly 23 is mounted to the frame between cross members 13 and 14 .
- the output of the drive assembly 23 is operatively connected to two drive belts 24 and 25 .
- Drive belt 24 is utilized to drive the components at the output end of the dispenser 10 . These will be described in more detail hereafter.
- the drive belt 25 is utilized to drive the infeed conveyor, generally designated at 26 .
- the infeed conveyor 26 has a plurality of O-rings 26 a which rotate around an input end shaft 27 and an output end shaft 28 .
- a U-shaped connector 29 is secured at one end to the frame. At the other end of the U-shaped connector 29 , the input end shaft 27 is mounted in suitable bearings to allow it to rotate.
- Two bearing blocks 30 are bolted to a plate 31 which is in turn bolted to horizontal member 20 .
- a driven shaft 32 is mounted in the bearing blocks 30 for rotation. The driven shaft 32 is cantilevered from the support side of the dispenser 10 .
- Shafts 33 through 36 are also cantilevered from the operating side of the dispenser 10 .
- Two bearing blocks 37 are bolted to a plate 38 .
- Shaft 33 is rotatably mounted in the bearing blocks 37 .
- Shaft 34 is rotatably mounted in the bearing blocks 39 and shaft 35 is rotatably mounted in the bearing blocks 41 .
- the shaft 36 is similarly supported by bearing blocks and a plate. It is understood that other suitable structures to support the shafts 33 through 36 in a cantilevered fashion may be utilized.
- Shafts 27 , 28 , 34 , 35 and 36 have grooves in which the O-rings 26 a are positioned.
- the shafts of the infeed conveyor 26 are suitably driven by the drive belt 25 .
- One suitable arrangement would be for the drive belt 25 to drive a sprocket gear positioned between the shafts 34 , 35 and 36 .
- the sprocket gear in turn would drive the shafts 34 , 35 and 36 .
- Shaft 34 has an extension on which a belt 42 is positioned.
- the belt 42 rotates as the shaft 34 is driven.
- the belt 42 also rotates around an extension of shaft 32 , thereby driving shaft 32 .
- a board magazine generally designated at 43 is shown in FIGS. 4 and 5.
- the board magazine 43 is carried on an adjustable cradle, generally designated at 44 and shown in FIG. 3.
- the cradle 44 includes base plates 45 and 46 which are bolted to the frame cross members 14 and 15 respectively.
- Standoffs 47 and 48 are connected to the base plates 45 and 46 by suitable means such as welding.
- Top plates 49 and 50 are secured to the standoffs 47 and 48 , again by suitable means such as welding.
- Bearing plates 51 and 52 are bolted to the top plates 49 and 50 .
- the bearing plates 51 and 52 have a top surface 51 a and 52 a .
- a horizontally slidable support stop is generally designated at 53 .
- the support stop 53 slides horizontally on top of the top surfaces 51 a and 52 a .
- the support stop 53 includes a cross member 54 which at one end is bolted to a multi-positioned stop member 55 at one end and another multi-positioned stop member 56 at its other end. Connected to the stop member 56 by an intermediate section 58 is another multi-positioned stop member 59 . Another multi-positioned stop member (not shown) is connected to the stop member 55 by an intermediate section 57 . All four stop members are similar and therefore only one will be described in detail, it being understood that the other stop members have similar construction.
- the stop member 56 is formed having three steps, thereby forming three support surfaces 60 , 61 and 62 . Each support surface 60 through 62 is at a different elevation.
- the support stop 53 is moved horizontally along the top surfaces 51 a and 52 a by simply pulling or pushing on the cross member 54 . As shown in FIG. 4, the support stop 53 is pushed in, toward the support side of the dispenser, at its maximum distance. It is movable toward the operating side in increments to position successively support surfaces 61 and 62 .
- Any suitable means to slidably connect the support stop 53 to the plates 51 and 52 may be utilized. For instance, a slot may be formed in the plates 51 and 52 . Then a shoulder bolt may be threaded into the bottom of the stop members 55 , 56 and 59 . The shoulder bolt would then slide in the slot and maintain the sliding relationship between the support stop 53 and the plates 51 and 52 without having the support stop 53 tilt.
- a ball detent may be located on the bottom of the stops and corresponding holes formed in the top surfaces 51 a and 52 a .
- the holes would be in alignment so that the ball detent would engage the holes when the support surfaces 60 through 62 are in the appropriate position. That is, there would be one location for locating the support surface 60 in a horizontal direction, another for support surface 61 and finally another for support surface 62 .
- a slidable board magazine support is generally designated at 63 .
- the support 63 includes a rectangular base which includes cross members 64 and 65 connected by suitable means, such as welding, to side members 67 and 67 a .
- suitable means such as welding
- FIG. 3 the construction of the magazine support is best shown toward the input end of the dispenser 10 and will therefore be described in more detail, it being understood that the construction at the output end is similar.
- Another cross member 71 is secured between the posts 68 and 69 .
- Cross member 71 is suitably connected, such as by welding, to two angle members 76 via brace 77 and connector 78 .
- the brace 77 is welded to the angle members 76 and the connector 78 is welded to the brace 77 at one end and to the cross member 71 at its other end.
- Rectangular guide posts 72 and 73 are secured to the bearing plates 51 and 52 .
- Machined bearing surfaces 74 are formed on the guideposts 72 and 73 to provide for a slidable connection with the matching bearing surfaces formed on the inside of the angles 76 . This allows the board magazine support 63 to slide up and down on the guide posts 72 and 73 .
- the slidable board magazine support is moved in a vertical direction by a suitable means such as a pneumatic Firestone Airstroke Lift Device 80 .
- the lift device 80 is secured at its bottom end to a frame member 81 which is positioned between the cross members 14 and 15 .
- the top end of the lift device which provides vertical movement, is in contact with a cross bar 82 whose ends are welded to plates 83 and 84 .
- the plates 83 and 84 are bolted to the cross members 64 and 65 respectively. Therefore, a vertical extension of the lift device 80 causes the cross bar 82 to move vertically and thereby moves the slidable board magazine support 63 in a vertical direction.
- FIG. 4 is a perspective view showing the top of the board magazine 43 while FIG. 5 is a perspective view of the bottom of the board magazine 43 .
- the board magazine 43 includes a base plate 283 which has eight elongate openings 283 a formed therein.
- the openings 283 a are formed in pairs and are for receiving the eight bolts 70 (as shown in FIG. 3) to secure the board magazine 43 to the slidable board magazine support 63 . Therefore, any movement vertically of the magazine support 63 carries with it the board magazine 43 .
- a central opening 283 b is formed in the base plate 283 .
- a pusher member 84 provides a motive force for pushing the boards 300 toward the output end or to the left, as shown in FIG. 4.
- the pusher member 284 slides on two plastic members 85 which are secured to the base plate 283 by suitable means such as screws.
- the base plate 283 is typically stainless steel and the boards to be dispensed do not slide well on stainless steel. Therefore, the plastic members 85 are utilized.
- the pusher member 284 has two block sections 284 a attached to each side. The two block sections 284 a are connected by a bracket 86 . As can be seen in FIG. 5, the block sections 284 a extend downward into the opening 283 b and act as a guide to keep the pusher member 284 in alignment along the center longitudinal axis.
- the motive force for the pusher member 284 is supplied by an Origa rodless cylinder 87 .
- the rodless cylinder 87 is well known and is commercially available.
- the rodless cylinder 87 has a translating attachment 87 a which is U-shaped and extends both above and below the rodless cylinder 87 .
- the translating attachment 87 is bolted to a plate 88 which has a cylindrical rod 88 a attached thereto.
- the cylindrical rod 89 extends into a hole which is drilled into the pusher member 284 . Therefore, any movement of the translating attachment 87 a is directly transferred to a corresponding movement of the pusher member 284 .
- a fence 89 has two arms 90 which have two rods 90 a and 90 b attached thereto.
- the arms 90 are connected to a bracket 91 and pivot about their point of attachment 91 a.
- Standoffs 92 are attached to the arm and bracket and are connected by O-ring springs 93 .
- the O-rings 93 provide a tension to keep the arms and bracket at a 90-degree angle. However, the O-rings stretch and allow the fence to be rotated downward, as viewed in FIG. 4, to allow for the loading of the boards.
- Air pressure is provided to the rodless cylinder 87 through three valves 94 , 95 and 96 .
- the valves 94 through 96 are secured to the underside of the base plate 283 .
- the valves 94 through 96 have an inlet conduit 94 a through 96 a which are each operatively connected by a hose to regulators 94 b , 95 b and 96 b .
- Each valve 94 through 96 has an outlet 94 c , 95 c and 96 c .
- the outlets 94 c through 96 c are all operatively connected to the rodless cylinder 87 by a suitable connecting hose (not shown).
- a source of pressurized air 97 is connected to the regulators 94 b , 95 b and 96 b .
- a typical source of pressurized air may have a pressure of approximately 100 psi.
- the regulators 94 b through 96 b may have a suitable pressure such as 55 psi for regulator 94 b , 38 psi for regulator 95 b and 25 psi for regulator 96 b . This would be varied, depending on the amount of pressure that is desired to be supplied to the rodless cylinder 87 .
- Each valve 94 through 96 has an associated spring-loaded cam follower which opens or closes the valve.
- the cam followers are identified as 98 .
- the cam follower for valve 95 is hidden from view in FIG. 5 but is similar to that shown for valves 94 and 96 .
- a shoe 99 is secured to the pushing member 84 and, as shown in FIG. 5, extends below the bottom of the base plate 283 . The shoe 99 has angled ends.
- the shoe contacts the cam follower and opens the valve which is associated with that cam follower.
- the shoe contacts the cam follower for 94 b providing the highest pressure.
- the shoe will allow the cam follower for 94 b to be released and contact the cam follower 98 for regulator 95 b , thereby reducing the pressure supplied to the cylinder 87 .
- This provides less force and this is repeated when regulator 96 b is actuated and 95 b is not.
- the pressure supplied is reduced in steps, the higher pressure is still in the cylinder 87 , and is gradually reduced as the shoe moves. It is therefore gradually reduced until it reaches the pressure of the next regulator, when the process is then repeated.
- a sensor 100 is mounted toward the output end of the dispenser 10 . Any suitable sensor 100 may be utilized. The sensor will sense the presence of the shoe 99 . When the shoe 99 has traveled toward the output end, it indicates that there is a low level of boards available to be dispensed and a suitable warning light may be activated by the sensor 100 .
- a backstop 101 is secured to the base plate 283 and provides for a stop for the boards which are loaded onto the board magazine 43 . The backstop 101 has a lower section 101 a which extends further in than the upper section 101 b . This feature is useful when different sized boards are utilized and allows for the contact of the boards at different heights.
- FIG. 4 At the end of the board magazine 43 , as shown in FIG. 4, are two uprights 102 which are secured to the base plate 283 .
- the uprights have a lower set of stops or tabs 103 which are secured to the uprights 102 by a screw 104 .
- the tabs 103 have slots so that the distance that the tabs 103 extend into the center of the board magazine 43 may be adjusted.
- top tabs 105 are secured to the top end of the uprights 102 .
- Middle stops or tabs 106 are mounted to a cylinder 107 which is mounted for 180-degree rotational movement on the upright 102 . Therefore, the tabs may be rotated in and out of position simply rotating the cylinders 107 . This is useful when different sized boards require different tabs.
- Tabs 106 are utilized when the smaller sized boards are run. Then, when larger boards are run, the tabs 106 are simply rotated out of the way. This provides for an easier board changeover. The tabs prevent the boards 300 from being pushed out of the board magazine 43 by the pusher 84 .
- a steering assembly generally designated at 108 .
- the steering assembly 108 provides for controlling the steering of the infeed conveyor 26 by providing lateral movement of the output end shaft 28 .

- the nut 131 is threaded and is welded to member 122 a .
- the knob 130 is rotated, the threaded rod rotates in the nut 131 and moves the bar 119 to the left, as viewed in FIG. 6. As will be seen later, this allows for the movement of the output end shaft 28 .
- Rotation of the knob 130 in the opposite direction will unscrew the threaded rod out of the nut 131 causing the bar 119 to move to the right, as viewed in FIG. 6.
- the output shaft 28 is mounted in two bearing blocks 132 .
- the bearing blocks are in turn mounted on a plate 133 by suitable bolts 134 .

- FIG. 10 The sequencing of the dispensing mechanism 193 is shown in FIG. 10. There, in the first position shown, the suction cups are adjacent the board 300 . The cylinder 197 is then actuated thereby causing the cam follower 221 to move in the cam track 219 a . This causes the board 300 to move through the positions as shown in the dotted line in FIG. 10. The board is placed in position between the pinch rollers which then move the board 300 to position “B” where it is held in position until it is needed to be dispensed under the next draft of bacon 400 . When the trailing edge of the board being dispensed passes a sensor, the cycle is repeated and the next board 300 is dispensed from the board magazine. The combination of the pivoting movement of the dispensing mechanism and the movement in the cam track provide a relatively horizontal removal of the boards from the stack of boards and then a movement up into the nip point between the rollers of the feeding mechanism.
- the board magazine 43 By having the board magazine 43 positioned directly under the conveyor 26 , a faster operation is possible as the boards 300 are more readily in position for dispensing. Further, it provides for accurate board placement as well as a large board storage capacity. Also, the three-position board magazine provides for quick change over between any of three board sizes with no time necessary for mechanics to change over between board sizes. Further, since the pressure or pushing force by the cylinder 87 decreases as boards are dispensed, the automatic decreasing of pressure allows for consistent board dispensing from a large horizontal magazine.
- the upper and lower suction cups 215 and 216 allow for either or both sets of vacuum cups to be run, depending upon the type of board to be dispensed. This again requires no set-up to change, simply a change of the valve 222 will accomplish this and no mechanic set-up time is required.
- the cantilevered design of many of the components results in a very open and easy-to-clean design. Also, the dual flip open conveyors at the point of board dispensing helps gain access for any possible jams as well as for ease of sanitation.
- FIG. 14 represents a schematic of the pressure system.
- the second embodiment of the pressure system utilizes a single source of pressurized air 550 and a single valve 502 that is controlled by a switching valve 500 , as opposed to the three regulators and cam followers used with respect to the first embodiment.
- a switching valve 500 having a cam follower 501 , is mounted on the dispensing mechanism 193 such that the L-bracket 205 actuates the cam follower 501 on the valve 500 .
- a valve 502 is mounted on the underneath side of the base plate 283 by suitable means such as bolts (not shown). The valve 502 is shown exploded away for clarity purposes.
- Each valve 500 and 502 have suitable exhaust ports for venting air to relieve pressure.
- pressurized air from a suitable source 550 is provided to the valve 500 and valve 502 through lines 560 and 570 , respectively.
- the cam follower 501 which is activated by the rotation of the L-bracket 205 , causes the air to be supplied via connecting line 504 to a pilot on valve 502 .
- a second connecting line 508 connects another pilot of the valve 502 to the valve 500 .
- pressurized air from the switching valve 500 provides air to the valve 502
- pressurized air flows via line 509 to the cylinder 87 . This results in the pushing member 284 pushing on the boards towards the pick-off point.

Description
- 1. Field of the Invention
- This invention relates generally to bacon board dispensers, and more particularly to a cantilevered design for a bacon board dispenser utilizing an easily adjustable board magazine having variable pressure and a dispenser having dual vacuum cups.
- 2. Description of the Prior Art
- Bacon board dispensers are commercially available and in use for conveying and depositing sliced bacon in shingled conditions in predetermined quantities (e.g., ½ pound, 1 pound, 2 pounds) onto so-called bacon boards for further packaging and insertion in a folded outer carton or other enclosures in evacuated and hermetically sealed envelopes of suitable film. Also, machines are available to package bacon on bacon boards or cards which are relatively thin and quite flexible and have a cutout window area for viewing the product.
- Due to the designs of such machines, they typically can package only 55 boards per minute because of their excess motion. Further, the bacon boards are of various size for the different quantities of bacon to be packaged. Adjustments are therefore necessary for the size of the bacon boards. This involves a setup which is typically quite consuming in converting the machinery from one size board to the other board. In addition, the dispensing of the boards is often dependent upon the size of the stack of bacon boards to be dispensed. Applicant is unaware of board magazines which compensate for the varying loads created by the varying amounts of bacon boards as they are dispensed.
- Sanitation requirements are also quite stringent for the packaging of bacon. In order to comply with the sanitation requirements, cleaning of the machines are necessary. Also, repairs are often necessary to the machines. The closed design of the prior art does not provide for ease of cleaning and maintenance.
- The invention is an apparatus for depositing predetermined quantities of sliced bacon in shingled condition on bacon boards. The apparatus includes a frame having an input end, output end, support side, and operating side. An infeed conveyor is operatively connected to a frame and a cantilevered output conveyor is operatively connected to the support side and extends towards the operating side. A bacon board dispenser mechanism is cantilevered and operatively connected to the support side and extends to the operating side. A bacon board magazine is positioned proximate the dispenser mechanism for supplying bacon boards to the dispenser mechanism. A cantilevered feeding mechanism is operatively connected to the support side and extends to the operating side. The feeding mechanism is for taking a bacon board dispensed by the dispenser mechanism and placing the bacon board under the sliced bacon, wherein the operating side is open thereby easing bacon board loading, cleaning and maintaining the apparatus.

A lift is operatively connected to the first frame for moving the first frame vertically. A cradle is operatively connected to the bearing member, and the cradle has a plurality of stops at different vertical heights. The cradle is slidable laterally to position a selected stop under the frame, wherein the frame is lowered to contact the selected stop, thereby positioning the frame.
- In another embodiment, the invention is an apparatus for depositing quantities of sliced bacon in shingled condition on bacon boards. The apparatus includes a frame having an input end, output end, support side and operating side. An infeed conveyor and output conveyor are operatively connected to the frame. A dispenser mechanism and feeding mechanism are also operatively connected to the frame. A bacon board magazine has a support surface for holding the bacon boards and a pushing member for pushing the bacon boards towards the dispensing mechanism and feeding mechanism. Means for applying pressure to the pushing member and means for sensing an amount of bacon boards on the support surface and lowering pressure applying to the pushing member as the amount of bacon boards decrease are provided.

- Referring to the drawing, wherein like numerals represent like parts throughout the several views, there is generally disclosed at10 a bacon board dispenser. The
dispenser 10 has a frame for supporting the various components of the dispenser. FIG. 2 shows the dispenser with various components exploded away. Further, the frame is shown in dashed lines. The frame includes an operatingside base member 11 connected to a supportside base member 12 by a plurality ofcross members 13 through 16.Cross member 13 is at the input end of thedispenser 10 andcross member 16 is at the output end of thedispenser 10.Members horizontal members upright member 22. Themembers 11 through 22 are connected by suitable means such as welding. It is of course understood that other suitable constructions of a frame may be utilized. However, as will be discussed more fully hereafter, it is noted that there is not an operating side frame which would effect access to the operating side of thedispenser 10. - A
drive assembly 23 is mounted to the frame betweencross members 13 and 14. The output of thedrive assembly 23 is operatively connected to twodrive belts Drive belt 24 is utilized to drive the components at the output end of thedispenser 10. These will be described in more detail hereafter. Thedrive belt 25 is utilized to drive the infeed conveyor, generally designated at 26. - The
infeed conveyor 26 has a plurality of O-rings 26 a which rotate around aninput end shaft 27 and anoutput end shaft 28. A U-shaped connector 29 is secured at one end to the frame. At the other end of the U-shaped connector 29, theinput end shaft 27 is mounted in suitable bearings to allow it to rotate. Two bearing blocks 30 are bolted to a plate 31 which is in turn bolted tohorizontal member 20. A drivenshaft 32 is mounted in the bearing blocks 30 for rotation. The drivenshaft 32 is cantilevered from the support side of thedispenser 10.Shafts 33 through 36 are also cantilevered from the operating side of thedispenser 10. Two bearing blocks 37 are bolted to aplate 38. Two bearing blocks 39 are bolted to aplate 40. Two bearing blocks 41 are bolted to another plate (not shown). Finally, two additional bearing blocks (not shown) are bolted to a plate (not shown) to support theshaft 36. Theplates dispenser 10.Shaft 33 is rotatably mounted in the bearing blocks 37.Shaft 34 is rotatably mounted in the bearing blocks 39 andshaft 35 is rotatably mounted in the bearing blocks 41. Theshaft 36, as previously mentioned, is similarly supported by bearing blocks and a plate. It is understood that other suitable structures to support theshafts 33 through 36 in a cantilevered fashion may be utilized.Shafts rings 26 a are positioned. - The shafts of the
infeed conveyor 26 are suitably driven by thedrive belt 25. One suitable arrangement would be for thedrive belt 25 to drive a sprocket gear positioned between theshafts shafts Shaft 34 has an extension on which abelt 42 is positioned. Thebelt 42 rotates as theshaft 34 is driven. Thebelt 42 also rotates around an extension ofshaft 32, thereby drivingshaft 32. - A board magazine generally designated at43 is shown in FIGS. 4 and 5. The
board magazine 43 is carried on an adjustable cradle, generally designated at 44 and shown in FIG. 3. Thecradle 44 includesbase plates frame cross members 14 and 15 respectively.Standoffs base plates Top plates standoffs Bearing plates top plates plates top surface 51 a and 52 a. A horizontally slidable support stop is generally designated at 53. Thesupport stop 53 slides horizontally on top of thetop surfaces 51 a and 52 a. Thesupport stop 53 includes across member 54 which at one end is bolted to a multi-positioned stop member 55 at one end and anothermulti-positioned stop member 56 at its other end. Connected to thestop member 56 by anintermediate section 58 is anothermulti-positioned stop member 59. Another multi-positioned stop member (not shown) is connected to the stop member 55 by anintermediate section 57. All four stop members are similar and therefore only one will be described in detail, it being understood that the other stop members have similar construction. Thestop member 56 is formed having three steps, thereby forming threesupport surfaces support surface 60 through 62 is at a different elevation. Thesupport stop 53 is moved horizontally along thetop surfaces 51 a and 52 a by simply pulling or pushing on thecross member 54. As shown in FIG. 4, thesupport stop 53 is pushed in, toward the support side of the dispenser, at its maximum distance. It is movable toward the operating side in increments to position successively supportsurfaces plates plates stop members support stop 53 and theplates support stop 53 tilt. Further, a ball detent may be located on the bottom of the stops and corresponding holes formed in thetop surfaces 51 a and 52 a. The holes would be in alignment so that the ball detent would engage the holes when the support surfaces 60 through 62 are in the appropriate position. That is, there would be one location for locating thesupport surface 60 in a horizontal direction, another forsupport surface 61 and finally another forsupport surface 62. - A slidable board magazine support is generally designated at63. The
support 63 includes a rectangular base which includescross members side members dispenser 10 and will therefore be described in more detail, it being understood that the construction at the output end is similar. There are twoposts side members 67 and have aplate bolts 70 to the board magazine, as will be described more fully hereafter. Anothercross member 71 is secured between theposts Cross member 71 is suitably connected, such as by welding, to twoangle members 76 viabrace 77 andconnector 78. Thebrace 77 is welded to theangle members 76 and theconnector 78 is welded to thebrace 77 at one end and to thecross member 71 at its other end. Rectangular guide posts 72 and 73 are secured to the bearingplates guideposts angles 76. This allows theboard magazine support 63 to slide up and down on the guide posts 72 and 73. - The slidable board magazine support is moved in a vertical direction by a suitable means such as a pneumatic Firestone
Airstroke Lift Device 80. Thelift device 80 is secured at its bottom end to a frame member 81 which is positioned between thecross members 14 and 15. The top end of the lift device, which provides vertical movement, is in contact with across bar 82 whose ends are welded toplates 83 and 84. Theplates 83 and 84 are bolted to thecross members lift device 80 causes thecross bar 82 to move vertically and thereby moves the slidableboard magazine support 63 in a vertical direction. - FIG. 4 is a perspective view showing the top of the
board magazine 43 while FIG. 5 is a perspective view of the bottom of theboard magazine 43. Theboard magazine 43 includes abase plate 283 which has eightelongate openings 283 a formed therein. Theopenings 283 a are formed in pairs and are for receiving the eight bolts 70 (as shown in FIG. 3) to secure theboard magazine 43 to the slidableboard magazine support 63. Therefore, any movement vertically of themagazine support 63 carries with it theboard magazine 43. Acentral opening 283 b is formed in thebase plate 283. A pusher member 84 provides a motive force for pushing theboards 300 toward the output end or to the left, as shown in FIG. 4. Thepusher member 284 slides on twoplastic members 85 which are secured to thebase plate 283 by suitable means such as screws. Thebase plate 283 is typically stainless steel and the boards to be dispensed do not slide well on stainless steel. Therefore, theplastic members 85 are utilized. Thepusher member 284 has twoblock sections 284 a attached to each side. The twoblock sections 284 a are connected by abracket 86. As can be seen in FIG. 5, theblock sections 284 a extend downward into theopening 283 b and act as a guide to keep thepusher member 284 in alignment along the center longitudinal axis. The motive force for thepusher member 284 is supplied by anOriga rodless cylinder 87. Therodless cylinder 87 is well known and is commercially available. There is a piston inside of therodless cylinder 87 which is acted upon by air pressure. Therodless cylinder 87 has a translatingattachment 87 a which is U-shaped and extends both above and below therodless cylinder 87. The translatingattachment 87 is bolted to aplate 88 which has acylindrical rod 88 a attached thereto. Thecylindrical rod 89 extends into a hole which is drilled into thepusher member 284. Therefore, any movement of the translatingattachment 87 a is directly transferred to a corresponding movement of thepusher member 284. - A
fence 89 has twoarms 90 which have tworods arms 90 are connected to abracket 91 and pivot about their point of attachment 91 a.Standoffs 92 are attached to the arm and bracket and are connected by O-ring springs 93. The O-rings 93 provide a tension to keep the arms and bracket at a 90-degree angle. However, the O-rings stretch and allow the fence to be rotated downward, as viewed in FIG. 4, to allow for the loading of the boards. Air pressure is provided to therodless cylinder 87 through threevalves valves 94 through 96 are secured to the underside of thebase plate 283. Thevalves 94 through 96 have aninlet conduit 94 a through 96 a which are each operatively connected by a hose toregulators 94 b, 95 b and 96 b. Eachvalve 94 through 96 has anoutlet outlets 94 c through 96 c are all operatively connected to therodless cylinder 87 by a suitable connecting hose (not shown). A source ofpressurized air 97 is connected to theregulators 94 b, 95 b and 96 b. A typical source of pressurized air may have a pressure of approximately 100 psi. The regulators 94 b through 96 b may have a suitable pressure such as 55 psi forregulator 94 b, 38 psi forregulator rodless cylinder 87. Eachvalve 94 through 96 has an associated spring-loaded cam follower which opens or closes the valve. The cam followers are identified as 98. The cam follower forvalve 95 is hidden from view in FIG. 5 but is similar to that shown forvalves shoe 99 is secured to the pushing member 84 and, as shown in FIG. 5, extends below the bottom of thebase plate 283. Theshoe 99 has angled ends. As will be described more fully hereafter, the shoe contacts the cam follower and opens the valve which is associated with that cam follower. When the boards fill theboard magazine 43, the shoe contacts the cam follower for 94 b providing the highest pressure. Then as the boards are used, the shoe will allow the cam follower for 94 b to be released and contact thecam follower 98 forregulator 95 b, thereby reducing the pressure supplied to thecylinder 87. This provides less force and this is repeated when regulator 96 b is actuated and 95 b is not. When the pressure supplied is reduced in steps, the higher pressure is still in thecylinder 87, and is gradually reduced as the shoe moves. It is therefore gradually reduced until it reaches the pressure of the next regulator, when the process is then repeated. If the shoe is not touching the cam follower, the valve is not operative and air will not flow out of the valve. Asensor 100 is mounted toward the output end of thedispenser 10. Anysuitable sensor 100 may be utilized. The sensor will sense the presence of theshoe 99. When theshoe 99 has traveled toward the output end, it indicates that there is a low level of boards available to be dispensed and a suitable warning light may be activated by thesensor 100. Abackstop 101 is secured to thebase plate 283 and provides for a stop for the boards which are loaded onto theboard magazine 43. Thebackstop 101 has a lower section 101 a which extends further in than the upper section 101 b. This feature is useful when different sized boards are utilized and allows for the contact of the boards at different heights. - At the end of the
board magazine 43, as shown in FIG. 4, are twouprights 102 which are secured to thebase plate 283. The uprights have a lower set of stops ortabs 103 which are secured to theuprights 102 by ascrew 104. Thetabs 103 have slots so that the distance that thetabs 103 extend into the center of theboard magazine 43 may be adjusted. Similarly,top tabs 105 are secured to the top end of theuprights 102. Middle stops ortabs 106 are mounted to acylinder 107 which is mounted for 180-degree rotational movement on theupright 102. Therefore, the tabs may be rotated in and out of position simply rotating thecylinders 107. This is useful when different sized boards require different tabs.Tabs 106 are utilized when the smaller sized boards are run. Then, when larger boards are run, thetabs 106 are simply rotated out of the way. This provides for an easier board changeover. The tabs prevent theboards 300 from being pushed out of theboard magazine 43 by the pusher 84. - Referring to FIGS. 2 and 6, there is shown a steering assembly, generally designated at108. The
steering assembly 108 provides for controlling the steering of theinfeed conveyor 26 by providing lateral movement of theoutput end shaft 28. Thesteering assembly 108 also provides for a cantilevered attachment of theoutput end shaft 28 to the support side of the bacon board dispenser. Atop bar 109 and abottom bar 110 are secured to a plate 111 by fourbolts 112. The plate 111 is secured to thehorizontal member 20 by suitable means such as welding. Afirst plate 113 is pivotally connected between thetop bar 109 and thebottom bar 110 by ashaft 114. Theshaft 114 is secured to thetop bar 109 by means of asetscrew 115 and secured to thebottom bar 110 by means of aset screw 116. Thefirst plate 113 is free to rotate around theshaft 114. Similarly, asecond plate 117 is pivotally mounted between thetop bar 109 andbottom bar 110 by means of ashaft 118. Theshaft 118 is similarly secured by means of set screws (not shown) and allows thesecond plate 117 to rotate about theshaft 118. - The other ends of the
plates bar 119. As best shown in FIG. 2, ashaft 120 is positioned in suitable bores in thesecond plate 117 andbar 119. Similarly, ashaft 121 rotatably mounts theplate 113 to thebar 119. This structure provides for a parallelogram to effectively move theoutput shaft 28. Apost 122 has a first end secured by suitable means, such as welding, to the top of thefirst plate 113. Thepost 122 has amember 122 a which extends 90 degrees from the top of thepost 122. Abar 123 is welded to across member 124 which is in turn secured bysuitable bolts 125 to thetop bar 109. Anextension member 126 is welded to thecross member 124 and extends upward. Anut 127 having a threaded aperture is secured to a post 128 which is in turn mounted to the top of theextension member 126. Extending through the threaded aperture of thenut 127 is a threadedrod 129 at one end of the threadedrod 129 is aknob 130 and at the other end is anut 131. Thenut 131 is threaded and is welded tomember 122 a. As theknob 130 is rotated, the threaded rod rotates in thenut 131 and moves thebar 119 to the left, as viewed in FIG. 6. As will be seen later, this allows for the movement of theoutput end shaft 28. Rotation of theknob 130 in the opposite direction will unscrew the threaded rod out of thenut 131 causing thebar 119 to move to the right, as viewed in FIG. 6. - The
output shaft 28 is mounted in two bearing blocks 132. The bearing blocks are in turn mounted on aplate 133 bysuitable bolts 134. Theplate 133 has afirst end 133 a and asecond end 133 b. Theplate 133 is configured to pivot at itsfirst end 133 a around ashaft 135. Theshaft 135 is held in position by four rod ends 136 through 139. Each of the rod ends have a threaded shaft at one end and a bearing at the other. The threaded shafts for rod ends 136 and 137 are secured to thebar 119 by suitable nuts. The bearings are positioned around theshaft 135. The rod ends 138 and 139 have their threaded shafts secured to theplate 133 and their bearings positioned around theshaft 135.Clamp collars 140 are positioned around the shaft and prevent lateral movement thereof. Thesecond end 133 b of theplate 133 is supported on a plastic bearing or stop 141 which is in turn secured to asupport bar 142. Thesupport bar 142 is secured to thefirst plate 113 by suitable means such asbolts 143. The parallelogram steering structure provides for the movement to the left or right of theshaft 28. Further, theshaft 28 may be lifted upward by means of ahandle 144. Thehandle 144 is connected to an L-bracket 145 which has one end welded to theplate 133. Therefore, when thehandle 144 is moved upward, theplate 133 is rotated around theshaft 135 and theshaft 28 also rotates around theshaft 135, thereby bringing upward the output end of theinfeed conveyor 26. - Referring to FIGS. 2 and 7, there is generally shown at146 a feeding mechanism. The
feeding mechanism 146 is cantilevered and connected to the support side of thedispenser 10 and extends toward the operating side of thedispenser 10. Referring to FIG. 2, it can be seen that anangled support 147 is secured to theside support 12 by suitable means such as welding. Theangled support 147 provides a basis for providing cantilevered support to various portions of thedispenser 10. One of these is thedispenser mechanism 146. Aplate 148 is secured to theangled support 147 by suitable means such as welding. The plate has a plurality ofapertures 148 a formed therein. Anotherplate 149 having a plurality ofcorresponding apertures 149 a is secured to plate 148 by suitable means such as bolts. Asupport bar 150 is welded to theplate 149 and provides for cantilevered support of thedispenser mechanism 146. Secured to thesupport bar 150 issupport member 151. Suitable means such as bolts may be used to connect thesupport bar 150 to thesupport member 151. Secured at opposite sides of thesupport member 151 are first and second bearing supports 152 and 153. Bearing 154 is operatively connected to thebearing support 153. Another bearing (not shown) is connected and carried by thefirst bearing support 152. Ashaft 155 is rotatably mounted in thebearing 154. Anotherbearing 156 is carried by thesecond bearing support 153. A similar bearing (not shown) is carried by thefirst bearing support 152. Ashaft 157 is rotatably carried by thebearing 156 and its equivalent bearing in thefirst bearing support 152. Thebearings shaft 155 is made of an appropriate material such as steel and is covered by asoft covering 155 a. Theshaft 155 is driven. Theshaft 157 is in contact with thesoft covering 155 a and is driven by friction from the rotation of thesoft covering 155 a. A plurality of smoothstainless steel fingers 159 are supported bybar 160. Thefingers 159 are curved slightly and terminate just prior to the nip point between theshafts fingers 159 help guide the board being dispensed to the nip point between theshafts protective shield 161 extends over theshafts feeding mechanism 146. Ahousing 162 surrounds the back portion of thedispenser mechanism 146, as viewed in FIG. 2. Between thehousing 162 and theprotective shield 161 is a slit through which thebacon boards 300 are dispensed after they are driven between theshafts gear housing 164. The drive pulley 163 has theshaft 155 operatively connected to it. Therefore, rotation of the drive pulley 163 causes an equivalent rotation of theshaft 155. - The
drive belt 24 drives ajack shaft 165. Thejack shaft 165 has a pulley (not shown) which, as viewed in FIG. 2, is located behind the brake/clutch mechanism 166. Thejack shaft 165 is mounted in abearing block 167 at one end and a similar bearing block (not shown) at its other end. Adrive pulley 168 is mounted on thedrive shaft 167 and drives the brake/clutch mechanism 166 via drive belt 169. The output of the brake/clutch mechanism 166 has a drive pulley (not shown) which is connected via adrive belt 170 to the drive pulley 163. Anidler pulley 171 is positioned between the pulley 163 and the brake/clutch mechanisms output. - A cantilevered output conveyor, generally designated at172 is shown in a perspective view, as viewed from underneath, in FIG. 8. An exploded view, as viewed from the top, is shown in FIG. 2. As will be described, the
output conveyor 172 is cantilevered from the support side of thedispenser 10 and extends toward the operating side of thedispenser 10. A connectingplate 173 hasapertures 173 a for connection, by suitable means such as bolts, to theangled support 147. Welded to the connectingplate 173 is astop member 174 which is at the bottom of theoutput conveyor 172. Acylindrical support rod 175 has itsfirst end 175 a welded to the connectingplate 173. A generally H-shapedconnector bracket 176 is rotatably mounted on therod 175. Thebracket 176 has twoside members member 176 c. At the ends of eachside circular collars connector bracket 176 is able to rotate about therod 175. Welded to the bottom of thesides bar 177. The bar rests on a plurality ofbumpers 178 which are fastened to thestop member 174. Thestop member 174 limits the downward rotation of the H-connector bracket 176. A drive pulley 179 is mounted on adrive shaft 180 that extends on both sides of the pulley 179. One end of theshaft 180 is rotatably mounted in thecircular collar 176 e. The other end of thedrive shaft 180 is operatively connected to thedrive shaft 181 of theoutput conveyor 172. Ahousing 182 is positioned over the pulley 179 and acts as a guard. A plurality of O-rings 183 are positioned around thedrive shaft 182 and ashaft 184. Similarly, O-rings 185 are positioned arounddrive shaft 181 andshaft 186. The O-rings shafts shafts end cap 187 has afirst housing 187 a which is connected by anintermediate bar 187 b to thesecond housing 187 c. The two bearings forshaft housing 187 a and the bearing forshaft 186 is inhousing 187 c. Thehousings end cap 187 has aflange 187 d which extends downward and is captured between a plate 189 (which is welded to the bar 177) and asecond plate 189 a by means of bolts. Ahandle 190 is welded to theplate 189 a. The drive pulley 179 is connected by adrive belt 191 to a pulley 192. The pulley 192 is mounted on thejack shaft 165. Theoutput conveyor 172 is able to be rotated, as viewed in FIG. 2, to rotate about theshaft 181. This allows theshaft 186 to move upward as thehandle 190 is moved upward. Theshaft 184 necessarily rotates downward. As will be described more fully hereafter, this rotation allows for access to the location where the bacon is placed on the bacon board. - A dispensing mechanism, generally designated as193, is best seen in FIGS. 2, 9, 11 and 12. The
dispensing mechanism 193 is for takingboards 300 from the board magazine and placing them into thefeeding mechanism 146 for subsequent placement under drafts of bacon. The sequential schematic view of this operation is shown in FIG. 10 where theboards 300 are being shown taken from the board magazine and being placed between therollers feeding mechanism 146. - The
dispensing mechanism 193 is supported by asupport bar 194. Thesupport bar 194 is welded to aplate 195 which is in turn bolted to a corresponding plate 196, which is in turn welded to theangled support 147. It can therefore be seen that thesupport 194 provides cantilevered support for thedispensing mechanism 193. Apneumatic cylinder 197, having anextendable arm 197 a, is mounted to an L-shapedbracket 199 which is in turn secured to thesupport 194 by suitable means such as welding. Aguard 198 is fastened to thecylinder 197. - A mounting
plate 201 is operatively connected to thesupport bar 194 by suitable means such as welding. Twoblock assemblies 202 are used to pivotally mountvacuum assemblies vacuum assemblies block assembly 202 has alower section 202 a that is suitably connected to the mountingplate 201 by suitable means such as welding. Anupper section 202 b is secured to thelower section 202 a by abolt 203. Thelower section 202 a andupper section 202 b each have half of a cylindrical bore formed therein and together form a cylindrical bore for the pivotal mounting ofshaft 204. - The
extension arm 197 a is connected to an L-bracket 205 having alower portion 205 a and a generallyvertical upright section 205 b. A generally rectangular block (not shown as it is hidden from view by blocks 202) is welded to theupright section 205 b. The block has a bore and theshaft 204 is positioned inside of the bore of the block as well as theblock assemblies 202. At the top of theupright section 205 b is welded across bracket 206. Thecross bracket 206 is also utilized for mounting bearinghouses houses bracket 206 bybolts 209. Theshaft 204 is mounted for rotational movement in thehouses 207, blocks 202 and through the block ofupright 205 b. Therefore, in viewing FIG. 12, as thearm 197 a is extended to the right, the upright 205 b pivots counterclockwise around theshaft 204 and thebracket 206 moves to the left as it pivots aroundshaft 204, carrying with it thehouses - A
shaft 212 is rotatably mounted inside of thebearing house 208. Theshaft 212 is captured between twoblocks shaft 212. Thevacuum assemblies blocks 214. Eachvacuum assembly upper suction cup 215 and alower suction cup 216. - A
cam base 217 is secured to theblock assemblies 202 bybolts 218. In viewing FIG. 12, the portion of thecam base 217 to the right has a slot in which the upright 205 b is positioned. Thecam 219 has acam track 219 a formed therein. Each of theshafts 212 are operatively connected to a base 212 a which is in turn secured to ayoke 220. Theyoke 220 has a slot formed therein. - A
cam follower 221 is inserted in bores formed on the split side of theyoke 220 and is therefore positioned in theyoke 220 and carried by theyoke 220, but is also positioned inside of thecam track 219 a. - Air control valves are mounted on a
bracket 223 which is carried by theyoke 219. Theair control valves 222 control flow of a vacuum to the vacuum cups 215 and 216 by suitable hoses. A separate control is provided, but not shown, for controlling theair control valves 222, as is well known in the art. - In operation, the multi-position bacon board magazine is moved into the correct position depending upon the size of the
bacon boards 300 to be dispensed. After one of the three preset heights are selected, thepusher member 284 is retracted by manually releasing the pressure on thecylinder 87. Then, a pneumatic valve (not shown) is activated to cause thepusher member 284 to apply pressure to thebacon boards 300. While not shown, it is understood that the pneumatic valve would be positioned between the source ofpressurized air 97 and the regulators 94 b through 96 b. Theinfeed conveyor 26 andoutput conveyor 172 are run continuously by thedrive assembly 23. Drafts of shingled strips ofbacon 400 are supplied to theinput conveyor 26 by means well known in the art. Depending upon the size of thebacon board 300 to be dispensed, either theupper suction cups 215 are activated and/or thelower suction cups 216 are activated. Thepusher member 284 pushes theboards 300 up against thesuction cups dispensing mechanism 193. If noboard 300 is detected as being in thedispensing mechanism 193, the vacuum cups 215 or 216 pull a board from the magazine and transfer it between thepinch rollers brake 166 and the rollers are rotated until theboard 300 is in the position “B” as shown in FIG. 10. The board is held stationary at this position until a draft of bacon is detected. The detector (not shown) activates a timer. After the timer times out the brake/clutch mechanism is activated thereby completing dispensing theboard 300 as the draft ofbacon 400 is going over the top of theboard 300. - The sequencing of the
dispensing mechanism 193 is shown in FIG. 10. There, in the first position shown, the suction cups are adjacent theboard 300. Thecylinder 197 is then actuated thereby causing thecam follower 221 to move in thecam track 219 a. This causes theboard 300 to move through the positions as shown in the dotted line in FIG. 10. The board is placed in position between the pinch rollers which then move theboard 300 to position “B” where it is held in position until it is needed to be dispensed under the next draft ofbacon 400. When the trailing edge of the board being dispensed passes a sensor, the cycle is repeated and thenext board 300 is dispensed from the board magazine. The combination of the pivoting movement of the dispensing mechanism and the movement in the cam track provide a relatively horizontal removal of the boards from the stack of boards and then a movement up into the nip point between the rollers of the feeding mechanism. - By having the
board magazine 43 positioned directly under theconveyor 26, a faster operation is possible as theboards 300 are more readily in position for dispensing. Further, it provides for accurate board placement as well as a large board storage capacity. Also, the three-position board magazine provides for quick change over between any of three board sizes with no time necessary for mechanics to change over between board sizes. Further, since the pressure or pushing force by thecylinder 87 decreases as boards are dispensed, the automatic decreasing of pressure allows for consistent board dispensing from a large horizontal magazine. The upper andlower suction cups valve 222 will accomplish this and no mechanic set-up time is required. - The cantilevered design of many of the components results in a very open and easy-to-clean design. Also, the dual flip open conveyors at the point of board dispensing helps gain access for any possible jams as well as for ease of sanitation.
- A second embodiment of a pressure system to provide pressure to the
cylinder 87 is shown in FIGS. 13 and 14. FIG. 14 represents a schematic of the pressure system. The second embodiment of the pressure system utilizes a single source ofpressurized air 550 and asingle valve 502 that is controlled by a switchingvalve 500, as opposed to the three regulators and cam followers used with respect to the first embodiment. A switchingvalve 500, having acam follower 501, is mounted on thedispensing mechanism 193 such that the L-bracket 205 actuates thecam follower 501 on thevalve 500. Avalve 502 is mounted on the underneath side of thebase plate 283 by suitable means such as bolts (not shown). Thevalve 502 is shown exploded away for clarity purposes. Eachvalve suitable source 550 is provided to thevalve 500 andvalve 502 throughlines cam follower 501, which is activated by the rotation of the L-bracket 205, causes the air to be supplied via connectingline 504 to a pilot onvalve 502. A second connectingline 508 connects another pilot of thevalve 502 to thevalve 500. When the pressurized air from the switchingvalve 500 provides air to thevalve 502, pressurized air flows vialine 509 to thecylinder 87. This results in the pushingmember 284 pushing on the boards towards the pick-off point. When the L-bracket 205 pivots back and the cam follower is released, pressure in therodless cylinder 87 goes to zero. This occurs at the same time as the suction cups are pulling a board from the magazine. Therefore, with no force being exerted by therodless cylinder 87, it is easier to pull a board out of the magazine. The remainder of the board magazine shown in FIG. 13 is the same as that previously described. - The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
