Definitions
- the present invention relates to case loader for containers according to the preamble of claim 1.
- One type of apparatus assembles the articles in parallel rows of the length of the case by moving the required number of articles sideways off the article conveyor. When the power number of columns is assembled, the entire caseload is dropped or lowered into the case.
- Another method and apparatus is to load the case row by row.
- the loading apparatus picks up a row of the required length and puts it in the case and then returns to pick up the next row of the same length, placing it in the case beside the first row.
- a third type of apparatus separates the articles into parallel columns as they are conveyed to the loading station.
- the articles at the lead position of each column are dropped into the case row by row.
- a variation of this is when the articles are round cans. They may be all slid into the case at the same time, the loading apparatus releasing an entire case load at once to roll into the case.
- US-A-4,124,967 discloses a conveyor system to package flexible plastic bags in a cardboard box. It appears to reorient the bags and drop them all at once from a hopper above the carton.
- the US-A-3,512,336 also discloses a conveyor system to package flexible plastic bags in a cardboard box.
- the system has a sorting conveyor which puts successive bags on four different parallel slow conveyors.
- the system has four intermitting fast conveyors which put the bags on chutes going into a hopper above the container. The trap door releases these into the cardboard box.
- the energy free loader is for example fed with bottles by a bottle conveyor.
- the bottles in the loader rest on a hinged ledge.
- a first sensor is activated.
- the cases are conveyed to the loader below and beside the position of the bottles.
- the cases are tipped up and, when in place, they activate a second sensor.
- both sensors are activated, the bottles drop and fall into a chute directing the bottles from the loading station and into the cases.
- the chutes reorient the bottles from a single line into the rows and columns required to fill the cases.
- the loader may fill one case entirely in one cycle, two cases half full on each cycle, or several cases partially full on each cycle.
- the ledge is reset to receive the next group of bottles. The force of the bottles tips the case back onto the conveyor and it is carried away.
- Claim 2 refers to a preferred embodiment of this invention.
- the energy free loader comprises several principal systems. These are the bottle support system 20, the bottle guide system 30, the bottle sensor system 40, the case sensor system 50, and the case conveying system 60. All of these systems are attached to the main frame 70.
- the bottle support system 20 is an extension of a conventional bottle conveyor such as a belt conveyor with end tray 21.
- the system includes a ledge 22 which extends from the belt conveyor for the length of four bottles in the system as shown.
- the ledge 22 has a vertical and horizontal plate and fits under and around one edge of the bottle. The bottles are urged onto the ledge 22 by the following bottles on the conveyor system.
- Each bottle is held upright in the bottle support system by plate 23 acting on the opposite side of the top of the bottle holding it in an upright position.
- Ledge 22 is attached to pivot 24 and counterbalanced by weight 25 holding the ledge in the horizontal position when fewer than four bottles are on the ledge.
- Attached to ledge 22 is roller 26, whose function is explained below.
- the bottle guide system 30 Beneath the bottle support system is the bottle guide system 30.
- the upper chute begins below the right hand two bottles in Fig. 1 and ends in a position to make those two bottles the upper course in the right case as shown in Fig. 1.
- the lower chute begins below the left hand two bottles and ends in a position to make the lower course in the left case in Fig. 1.
- Behind the ledge and extending across the loader is bottle guide 33.
- Above the lower chute is flexible deflector 34. Not shown are suitable side guides which will prevent lateral or rotational movement of the bottles as they move down the chutes.
- Bottle sensor system 40 detects when there are four bottles in the bottle support system 20. All of the bottles are urged along the ledge 22 by the following bottles on the bottle conveyor system. If, for some reason, there are missing bottles, it will take longer for the four bottles to be in place.
- the lead bottle presses on bottle stop 42 attached to lever arm 41 which is pivoted at 47.
- roller support 43 on which rides roller 26.
- roller stop 44 is roller stop 44.
- lever arm 45 On which is attached case lever hook 46. Not shown is a stop which limits the movement of lever arm 41.
- the case conveying system 60 includes a conventional conveyor chain. On the side of the conveyor away from the loader is inclined bar 62 which rises from beneath the conveyor and one side of the case to an elevation to tip the case towards the bottle support system. On the other side of the conveyor are side supports 63, 64, and 65 which hold the cases in the tipped position. The cases are prevented from moving further in the tipped position by case sensor system 50 and the end frame 66.
- Case sensor system 50 contains case lever 51 which is pivoted at 52.
- the case lever arm 51 includes finger 53 which cooperates with the case lever hook 46.
- the case lever 51 is pivoted by the leading case being pushed into the final case loading position by following cases on the conveyor system.

- the case arm 54 is prevented from further movement by end frame 66.
- the bottles are continuously conveyed by the bottle conveyor across tray 21 to the bottle support system 20.
- the following bottles urge the four leading bottles to slide across ledge 22 and plate 23 until the lead bottle strikes bottle stop 42.
- case lever finger 53 prevents the lever arm 41 from moving and the four bottles remain on ledge 22, which is held in the horizontal position by roller 26 resting on roller support 43.
- the cases are pushed along the case conveyor by the following cases.
- the leading case strikes the inclined bar 52 it will tilt and rise above the conveyor, thus losing contact with the conveyor. It rests on inclined bar 62 and side supports 63 and 64 and is pushed forward by the following cases.
- As the case approaches the case loading position it has tilted beyond top dead center and is then supported entirely by side supports 65 along the side and not bar 62.
- the inclined bar 62 does not extend to the final case loading position.
- the lead case strikes case arm 54 pushing it against end frame 66.
- the case need only move the case arm enough to allow finger 53 to disengage from case lever hook 46, thus allowing lever arm 41 to pivot freely.
- the two bottles which go through the lower chute to the trailing case form the lower course in that case.
- the two bottles which go through the leading case form the upper course in that case.
- Those two bottles have sufficient momentum to tilt the case, or pivot it around support bars 63 and 64 back onto the conveyor chain which removes the case from the loader.
- lever arm 41 Immediately after the bottles fall from the bottle support system the lever arm 41 will be biased back to its original position by the weight of lever arm 45. It is prevented from returning to that position because roller 26 is riding on roller stop 44. When the bottles have fallen below ledge 22, weight 25 will bias the ledge back to the horizontal position, thus bringing roller 26 back up above roller support 43 and allowing the feed-in lever to return to its original position.

- This comprises four chutes or slides 35, 36, 37, and 38.
- the inner chutes, 36 and 37 are indentical in design and guide those two bottles down and to one side when they are released by the support system.
- Outer chutes 35 and 38 are mirror images of each other, guiding the outer two bottles in an S-shaped route down and to one side and on top of the bottles in chutes 36 and 37.
- the two central bottles in chutes 36 and 37 fall directly into the lower position in the case. Because the chutes are shorter than chutes 35 and 38, those two bottles arrive into the case slightly ahead of the other two bottles which follow the S-shaped chutes 35 and 38 and become the top level in the case.

Abstract
Description
- The present invention relates to case loader for containers according to the preamble of claim 1.
- Various methods and apparatus for loading articles in cases are known in the prior art. One type of apparatus assembles the articles in parallel rows of the length of the case by moving the required number of articles sideways off the article conveyor. When the power number of columns is assembled, the entire caseload is dropped or lowered into the case.
- Another method and apparatus is to load the case row by row. The loading apparatus picks up a row of the required length and puts it in the case and then returns to pick up the next row of the same length, placing it in the case beside the first row.
- A third type of apparatus separates the articles into parallel columns as they are conveyed to the loading station. The articles at the lead position of each column are dropped into the case row by row. A variation of this is when the articles are round cans. They may be all slid into the case at the same time, the loading apparatus releasing an entire case load at once to roll into the case.
- US-A-4,124,967 discloses a conveyor system to package flexible plastic bags in a cardboard box. It appears to reorient the bags and drop them all at once from a hopper above the carton.
- The US-A-3,512,336 also discloses a conveyor system to package flexible plastic bags in a cardboard box. The system has a sorting conveyor which puts successive bags on four different parallel slow conveyors. The system has four intermitting fast conveyors which put the bags on chutes going into a hopper above the container. The trap door releases these into the cardboard box.
- It is an object of this invention to eliminate the elaborate machinery required to assemble a caseload of articles and lower it into the case and similarly to eliminate hydraulic and electric motors required to move and reorient the various articles while putting them in the case so that a practically energy free loader will be obtained.
- This object of the invention is being solved by the characterizing features of claim 1.
- The energy free loader according to the invention is for example fed with bottles by a bottle conveyor. The bottles in the loader rest on a hinged ledge. When the number of bottles required to fill the carton is present in the loader, a first sensor is activitated. The cases are conveyed to the loader below and beside the position of the bottles. The cases are tipped up and, when in place, they activate a second sensor. When both sensors are activated, the bottles drop and fall into a chute directing the bottles from the loading station and into the cases. The chutes reorient the bottles from a single line into the rows and columns required to fill the cases. The loader may fill one case entirely in one cycle, two cases half full on each cycle, or several cases partially full on each cycle. When the bottles have dropped, the ledge is reset to receive the next group of bottles. The force of the bottles tips the case back onto the conveyor and it is carried away.
- The present invention is characterized by a very simple structure which can be worked at minimum energy. Claim 2 refers to a preferred embodiment of this invention.
- The invention will be better understood when consideration is given to the following detailed description of two embodiments thereof. Such description makes reference to the annexed drawings wherein:
- Fig. 1 is a perspective view of the energy free loader with bottles on the ledge and cases in place ready to receive them;
- Fig. 2 is a selection on lines 2-2 of Fig. 1 looking toward the boxes;
- Fig. 3 is an end view of the energy free loader showing the bottles in solid lines on the ledge and in dashed line about to enter the cases;
- Fig. 4 is a cross-sectional view on lines 4-4 of Fig. 3 showing the untripped position in solid line and the tripped position in dashed lines;
- Fig. 4A is an enlarged view of the roller and roller support shown in Fig. 4;
- Figs. 5, 6 and 7 show the bottle and pivoted ledge in the support, partially tripped, and fully tripped position;
- Fig. 8 is a front view of the energy free loader showing the boxes being tilted;
- Fig. 9 is a perspective view of an alternate form of the energy free loader.
- The energy free loader comprises several principal systems. These are the
bottle support system 20, thebottle guide system 30, thebottle sensor system 40, thecase sensor system 50, and thecase conveying system 60. All of these systems are attached to themain frame 70. - The
bottle support system 20 is an extension of a conventional bottle conveyor such as a belt conveyor withend tray 21. The system includes aledge 22 which extends from the belt conveyor for the length of four bottles in the system as shown. Theledge 22 has a vertical and horizontal plate and fits under and around one edge of the bottle. The bottles are urged onto theledge 22 by the following bottles on the conveyor system. Each bottle is held upright in the bottle support system byplate 23 acting on the opposite side of the top of the bottle holding it in an upright position.Ledge 22 is attached topivot 24 and counterbalanced byweight 25 holding the ledge in the horizontal position when fewer than four bottles are on the ledge. Attached toledge 22 isroller 26, whose function is explained below. - Beneath the bottle support system is the
bottle guide system 30. This includes anupper chute 31 for two bottles and alower chute 32, also for two bottles. The upper chute begins below the right hand two bottles in Fig. 1 and ends in a position to make those two bottles the upper course in the right case as shown in Fig. 1. The lower chute begins below the left hand two bottles and ends in a position to make the lower course in the left case in Fig. 1. Behind the ledge and extending across the loader isbottle guide 33. Above the lower chute isflexible deflector 34. Not shown are suitable side guides which will prevent lateral or rotational movement of the bottles as they move down the chutes. -
Bottle sensor system 40 detects when there are four bottles in thebottle support system 20. All of the bottles are urged along theledge 22 by the following bottles on the bottle conveyor system. If, for some reason, there are missing bottles, it will take longer for the four bottles to be in place. When the four bottles are in place, the lead bottle presses onbottle stop 42 attached tolever arm 41 which is pivoted at 47. Below thelever arm 41 isroller support 43 on whichrides roller 26. Depending below theroller support 43 isroller stop 44. Below the roller stop ishorizontal lever arm 45 on which is attachedcase lever hook 46. Not shown is a stop which limits the movement oflever arm 41. - The
case conveying system 60 includes a conventional conveyor chain. On the side of the conveyor away from the loader is inclinedbar 62 which rises from beneath the conveyor and one side of the case to an elevation to tip the case towards the bottle support system. On the other side of the conveyor areside supports case sensor system 50 and theend frame 66. -
Case sensor system 50 containscase lever 51 which is pivoted at 52. Thecase lever arm 51 includesfinger 53 which cooperates with thecase lever hook 46. Thecase lever 51 is pivoted by the leading case being pushed into the final case loading position by following cases on the conveyor system. The casecontacts case arm 54 which is also connected to pivot 52. Thecase arm 54 is prevented from further movement byend frame 66. - The bottles are continuously conveyed by the bottle conveyor across
tray 21 to thebottle support system 20. The following bottles urge the four leading bottles to slide acrossledge 22 andplate 23 until the lead bottlestrikes bottle stop 42. - If a case is not in position to be loaded the
case lever finger 53 prevents thelever arm 41 from moving and the four bottles remain onledge 22, which is held in the horizontal position byroller 26 resting onroller support 43. - The cases are pushed along the case conveyor by the following cases. When the leading case strikes the
inclined bar 52 it will tilt and rise above the conveyor, thus losing contact with the conveyor. It rests oninclined bar 62 and side supports 63 and 64 and is pushed forward by the following cases. As the case approaches the case loading position it has tilted beyond top dead center and is then supported entirely by side supports 65 along the side and not bar 62. Theinclined bar 62 does not extend to the final case loading position. The lead case strikescase arm 54 pushing it againstend frame 66. The case need only move the case arm enough to allowfinger 53 to disengage fromcase lever hook 46, thus allowinglever arm 41 to pivot freely. - When
lever arm 41 pivots, theroller 26 falls off ofroller support 43 thus pivotingledge 22 to a vertical position and releasing the bottles. Each of the four bottles falls againstbottle guide 33 and then into thechutes lower chute 32 first strikeflexible deflector 34 which serves to guide them and to limit their velocity to guard against denting the bottles. - The two bottles which go through the lower chute to the trailing case form the lower course in that case. The two bottles which go through the leading case form the upper course in that case. Those two bottles have sufficient momentum to tilt the case, or pivot it around support bars 63 and 64 back onto the conveyor chain which removes the case from the loader.
- Immediately after the bottles fall from the bottle support system the
lever arm 41 will be biased back to its original position by the weight oflever arm 45. It is prevented from returning to that position becauseroller 26 is riding onroller stop 44. When the bottles have fallen belowledge 22,weight 25 will bias the ledge back to the horizontal position, thus bringingroller 26 back up aboveroller support 43 and allowing the feed-in lever to return to its original position. - A second embodiment is shown in Fig. 9. The only difference is in the
bottle guide system 30. This comprises four chutes or slides 35, 36, 37, and 38. The inner chutes, 36 and 37, are indentical in design and guide those two bottles down and to one side when they are released by the support system.Outer chutes chutes chutes chutes chutes - In this embodiment one case is entirely loaded in one cycle.
- The loader could equally load a 3 x 3 case in one or three cycles or a 2/4 case in one, two or four cycles. The operation herein disclosed is applicable to cans or bottles or containers or various configurations.
