6 Claims.
This invention appertains to a dispensing: apparatus and is particularly constructed for use in conjunction with automatic carton packing machines.
The primary object of this invention is=to supply or feed. at regular intervals a number of packages,.the packages or articles being supplied to the packing machine.
Another important. object of this invention is to construct a completely automatic article or package dispensing machine, which requires no attendants whatsoever during normal operation, and which may be made an adjunct to the con.- ventional conveyor of a packaging machine and which maybe driven by the conveyor;
Another" important object; of this invention is: to move at timed intervals a plurality of vertically stacked articles onto a rotary conveyor; the apparatus provided functioning to push. the. bottom orlowermost article in. the stack. out from the stack onto the conveyor, without disturbing the-stack.
These and ancillary? objects and structural features of. merit are attained by this invention, a. preferred embodiment of which is set forth in the following description and illustrated in the accompanying drawings. wherein;
Figure l is a top" plan. view of the dispensing apparatus, constructed in accordance with the principles of this: invention, and illustrating the same, with a portion of the table top' removed to illustrate in. plan the collapsible carriage or means provided for pushing the articles from the stack onto the conveyor;
Figure 2 is a. longitudinal. vertical sectional view taken on line 2--2 of Figure 1;
Figure. 3 is a similar view, as" Figure 2, but il-- lustrating the device. in its penultimate position:
Figure 4. is a transverse sectional. view taken on. line 4i-l' of Figure 2;
Figure 5 is;.a side elevational view; and
Figure 6 is a view inperspective of thecollapsible carriage Referring now more particularly to the accompanying drawings, the article or package dis-V pensing apparatus Ill includes a supporting frame l2. The supporting frame l2 consistsof a front pair of standards or legs I4 and a rear pair of standards IS, the aligned standards of each pair being joined at their upper ends by longitudinal bars [8, as shown in Figure l.
A shaft is rotatably journaled between the front pair ofstandards 14 and supportsthe driven end or reach 22 of a conveyor 24. The shaft also functions as the drive means for the dispensing mechanism, carried by the frame, as will. be explained.
Withrespect to the dispensing mechanisms, a pair of longitudinally extending inturned channel bars 26 and Rare provided and function as trackways for a reciprocable collapsing carriage or pushing means 30., The trackways 26 and 28 are mounted on transversely positioned supportingbars 29 and extend parallel with the bars I8. An angle iron 32 is mounted transversely between the rear ends of tracks and forms a fixed stop to limit the rearward movement of the carriage.
A cover or top 34 is provided and includes a top section 36 having depending sides or flanges 38 which enclose the tracks and the carriage. The top 36 extends centrally at its raised portion between a pair of vertical angle irons 40 and 42 which are disposed complementary to a. pair of vertical angle irons and 46. The angle irons 40 and 42 are tapered or flared upwardly and rearwardly, as seen in Figure 2 and the angle irons 44. and 46 function to form a vertical guideway for retaining a plurality of articles 48 in the form of a stack, with the lowermost or bottom articlemounted on the top of the channel bars 26 and 28, as seen in Figure 2. It can be seen that the articles may be easily held within the angle irons, which serve as guide means to retain the articles in proper vertical alignment.
Attentionis now directedto Figure 6, wherein the carriage 30 is illustrated in detail; The car-- riage 30 includes a pair of longitudinally spaced shafts or axles 50 and 52, which. have'wheels 54 disposed on their? opposing terminals and positionedin the tracks 26 and 28. Bars 56 and 58 connect: the. shafts and maintain the same in fixed; relationship. A pair of: links 60' and 62 extend vertically from. the axle 52 and are pivotally joined at their upper ends by pivot pins 64 to the forward terminals of connecting bars 66 and 68. A pusher bar 10, which is transversely curved, is mounted on the forward end of the connecting bars 66 and 68 and is provided to contact the packages or articles 48, in a manner to be described. The rearward ends of the connecting bars 66 and 68 are pivotally joined by pins 'H- to the upper terminals of vertical links 72 and 14. The links 12 and 14 are transversely apertured intermediate their ends and are thereby mounted for rotation on the axle 59, the links being spaced from the bars 56 by bearings 16. A transverse rod 18 is secured between the lower ends of the links 12 and 14 and functions as part of a raising mechanism, as will be seen.
Means .is' provided and is preferably responsiveto the rotary movement of the conveyor for effecting a reciprocatory movement of the carriage and thereby moving the same relative to and away from the stack 48. Thus, a supporting structure 80 is carried by the frame and includes an angular framework 82 and a diagonally extending angle iron 84 which is mounted at its upper end to the brace bar 29 and secured at its lower end to a transverse brace bar 86 disposed between the rear pair of standards I6. A shaft 88 is rotatably journaled in the framework 82 and has one end projecting outwardly therefrom, the end being spaced therefrom by a bearing collar 95. A sprocket wheel 92 is secured on the extending end of the shaft and connected to a sprocket wheel 94 mounted on the shaft 26 by a connecting chain 95. Of course, it is apparent that any suitable type of drive transmitting means may be utilized and thus, a gear train may be mounted between the shafts 20 and 28 for effecting rotation of the shaft 88, responsive to rotation of the shaft 29.
The inner end of the shaft 88 is rotatably journaled in the bar 84 and a crank 98 is secured on the terminal of the shaft. A crank IE is rotatably journaled on the axle 5i) and is held thereon by bearings :92. An actuating arm IE4 is formed with an upper clevised end I86 which is pivotally secured by a transverse pivot pin I68 to the forward end of the crank Illk]. The opposing end of the actuating arm its is provided with a collar II?) to receive a journal pin H2, which is disposed through the bar 84. A connecting rod II4 is pivotally secured by a pin II6 to the crank 93 and is provided with an opposing exteriorly threaded end H8 on which a collar I20 is concentrically disposed and adjustably secured thereon for longitudinal adjustment by complementary nuts I22 disposed at the opposing ends thereof. The collar or sleeve IE5] is pivotally secured as at I24 to the actuating arm I04 and, thus, rotation of the shaft 88 is translated into reciprocal movement of the carriage in a rectilinear path on the tracks by means of the connecting rod H4 and the actuating arm I04 which is pivotally secured to the rod and connected to the crank I60 journaled on the carriage axle 50.
As the carriage is moved forwardly on the tracks, relative to the stack of packages, means is provided for collapsing the carriage, responsive solely to the forward movement thereof on the tracks. In this respect, it is to be noted that the carriage is normally maintained in a raised position, with the rear links I2 and I4 and the front links 60 and 62 in vertical parallel relationship by means of a depending stop I26, which is welded at its upper end to a bar IE3, the bar being formed with transverse openings I39 at its opposing ends to mount it on the axles 58 and 52. A rod or stop member I32 is fixed between the tracks and may be welded or otherwise secured to the bottoms of the tracks disposed transversely therebetween, the stop being fixed in advance of the stack of packages. Thus, as the carriage is moved forwardly, relatively to the stack, the depending ends of the links I2 and '54 will contact the stop and ride up over the stop, causing the connecting bars 86 and 68 to move forwardly, with the links Gil and 62 pivoting forwardly and downwardly, so that the entire carriage is swung to a collapsed position, as seen in Figure 3. In this respect, it is to be noted that the carriage, when collapsed is of a height less than the height of the tracks 26 and 28, so that the carriage can move under the stack, as seen in Figure 3, without disturbing the lowermost package therein, after the original bottom package is moved out onto the conveyor. As the carriage is moved rearwardly, it is maintained in a collapsed position, passing under the stack, until it clears the stack. Means is then provided for raising the carriage and includes a spring I34, which is connected between the end of the connecting rod IM and the axle I8. It is to be noted that the connecting bars 66 and 68 are formed on their underside with notches or recesses I36, which are provided to seat on the front axle 52, thus permitting the carriage to collapse to its full extent. Also, the bars seating on the axle 52, plus the weight of the stack, aid in retaining the carriage in a collapsed position, during its rearward travel until it clears the stack, thus overcoming the force of the spring. In the event that the spring I 34 should, after extensive use, fail to snap the carriage into an upright position, the stop formed by the angle iron 32 at the rear of the tracks will contact the lower end of the links I2 and M and cause the carriage to raise.
In operation, it can be seen that packages can be stacked within the guiding and stacking means provided and that, as a result of the relatively short guides 49 and 42, the packages can be easily and conveniently stacked to a reasonable height without much effort.
As the conveyor is driven by a suitable means, the shaft 25] will rotate and impart rotation to the shaft 88, which through the crank 93, the connecting rod H4, the actuating arm I04 and the crank I98 journaled on the rear axle 59 of the carriage, will impart a reciprocable movement to the carriage. As the carriage advances toward the stack, the bottom package I50 in the stack will be pushed forwardly and outwardly from the stack by the pusher bar 70. At that time, the carriage will be collapsed through the contact of the stop I32 by the rear links I2 and M. This will give the package a further push and advance it onto the conveyor 24, at the same time, collapsing the carriage, so that the stack is dropped down onto the track and the carriage will move forwardly and then rearwardly, without disturbing the stack.
