The frame is provided with a pair of vertically spaced angle iron sections 16 and 18 secured together by a plurality of vertical angle irons 19 so as to form an open -box structure 20. The frame 12 is rectangu- 1er in configuration, as best seen in FIG. 6, and the upper spaced parallel angle irons 22, as best seen in FIGS. 5 and 6, form guide means or tracks along which ride the rollers 24 of the carriage 14 as hereinafter described.
The frame 12 is provided with two spaced parallel angle irons 26, as best seen in FIG. 6, which extend between the longitudinal angle irons 22. These transverse angle irons form a slot 28 therebetween for causing the moving carriage 14 to reciprocate back and forth along the longitudinal angle irons 22, as hereinafter described.
The frame 12 is further provided with a drive motor 30 as best seen in FIGS. 3 and 6 adjacent one end thereof and having a reduction gear 32 and a drive shaft 34 extending therefrom with a drive sheave 36 connected to the end thereof.
The frame is further provided with a first driven shaft 38 as best seen in FIGS. 2 and 6, which extends parallel to the longitudinal angle irons 22, and is secured to the frame by any suitable means. The driven shaft 38 is provided with a variable sheave `40 operatively connected to the sheave 36 by a drive belt 42 as seen in FIGS. 2, 3, 5 and 6.
The opposite end of the driven shaft 38 is provided with another sheave 44, and the sheave 44 carries a reversed belt 46 which is connected to a sheave 48, see FIGS. 1, 2, 4, for rotating a slatted horizontally extending drum 50, see FIGS. 1, 2 and 5. The slatted drum 50 is rotated by the belt drive and is carried by two vertical -bars 52 secured to the opposite ends of the frame 12, FIGS. 2 and 4. The drum 50 feeds the strip material from a cutting machine not forming part of the present invention.
Also disposed on the driven shaft 38 is a triple pulley sheave 54 which can slide along the end of the shaft 38 adjacent the sheave 44, FIGS. 1, 2, 6 and 7. The shaft 38 is provided with a key 56 along which the sheave 54 slides as seen in FIGS. 2, 6 and 7. The sheave 54 is operatively connected to the fork 58, see FIGS. 2 and 7, which is connected to the carriage 14 to slide the sheave 54 along the 4 key way 56 when the carriage reciprocates as hereinafter described.
Referring to FIGS. 3, 4 and 5, it will be seen that the carriage 14 is constructed of angle irons and is provided with spaced vertical angle irons 60 between which extends transverse horizontal angle iron 62. A horizontal platform or table 64 is secured to the intermediate transverse angle iron i62 for receiving thereon containers or boxes 66 shown in FIG. 5, for receiving the strip material therein to fold and package the strip material in the box. The platform `64 is also provided with transversely extending slots 68 through which extend swinging arms 70, FIGS. 5 and 8. The carriage rollers 24 which move along the horizontal angle irons 22 of the frame |12 are disposed on the lower ends of the vertical angle irons 60 of the carriage, FIG. 6.
The swinging arms 70 are pivotally connected at their mid-points, as indicated at 72 in FIG. 5, to the carriage. The lower end of the swinging arms 70 is provided with a counterweight 74, while the upper end of the arms is provided with a pair of spaced rollers 76, as best seen in FIGS. 5 and 8. The rollers are secured to the upper ends of the arms 70 by a bracket structure 78.
The carriage carries a driven shaft 80, see FIGS. 2, 3, 4, 5 and 6, which is supported in bearing `82 carried by the angle irons y62. The carriage driven shaft is driven by belts 84 carried by the sheave 54 and the sheave 86 carried by the shaft 80. The carriage driven shaft 80 is disposed on the side of the carriage opposite from the frame to which the driven shaft 38 of the frame is connected.
The carriage is provided with spaced eccentric sheaves 88, see FIGS. 3, 4, 5 and 6, secured to the carriage by stub axles 90, journaled in vertical struts 92, secured to the carriage. The eccentric sheaves 88 are disposed on the carriage on the same side as the driven shaft 38 is disposed on the machine. The sheaves 88 are double pulley sheaves and are provided with eccentric rollers or pins 94 pivotally connected to one end of a Pitman arm 96. 'Ihe other end of the Pitman arm 96 is pivotally connected at 98 to the swinging arm 70 between the pivot point indicated at 72 and the counter weight 74 on the bottom end thereof.
The carriage driven shaft 80 is provided with spaced sheaves 100 carrying endless belts 102 for driving the eccentric double sheaves 88.
The endless belt 102 carried by a sheave 100 extends toward and over the eccentric double sheave 88, and then back to the sheave 100 thereby driving the eccentric double sheave from the sheave 100 as best seen in FIGS. 5 and 6.
The endless belt 106 carried by the other half of the double sheave 88 extends around a double sheave 108 carried by the swinging arm 70 adjacent the pivot point of the arm, and another section 110 of the belt 106 as indicated in FIG. 5, extends upwardly and over a sheave 112 connected to the roller shaft so as to rotate the roller 76 in the direction of the arrow indicated in FIG. 5.
Thereafter, the section .114 of the belt extends down and around another double sheave 116 carried on the upper end of the swinging arm 70, as seen in FIG. 5, and the section 118 of the belt extends up and over another sheave 120 which is connected to the other roller 76 so as to rotate it in the opposite direction indicated by the arrow in FIG. 5, and in an opposite direction from the .tirst mentioned roller 76. Thereafter, the belt section 122, as best seen in FIG. 5, extends down over the double sheave 116 and the belt section 124 then extends downwardly and over the double sheave 108 again, after which the belt section 106 extends over the double eccentric sheave 88 as indicated in F'IG. 5. Thus, a continuous endless belt is disposed on the double eccentric sheave 88 and the roller sheaves 112 and 120 and the double sheaves 116 and 108 carried by the swinging arm 70. This belt drive will cause the swinging arm to swing back and forth or from side to side of the carriage and will cause the rotating rollers 76 to swing back and forth carrying the strip of material 128 between the rollers and feeding it into the containers 66, as indicated in dotted lines intl-TIG. after the strip of material has been received over the slatted drum 50 from the guide arm and fork 130 sceured to thev upper portion of the bars 52 by a horizontal barl 132.
The carriage 14 is reciprocated back and forth along the longitudinal angle iron 22 of the fixed frame 12 by a horizontal eccentric sheave 134, as best seen in FIGS. 2, 5 and I6. The sheave .-134 is supported by a vertical stub axle 136, see FIGS. 2, 5 and 6, journaled in a bracket structure |138 secured to the carriage 14. 4 The sheave 134 is provided with an eccentric pin 140 which extends therebelow land is disposed between the spaced transverse angle irons 26 as best seen in FIGS. 2, 5 and y6. The sheave 134 is driven by an endless belt '142 which is carried by a sheave 144 secured to the carriage driven shaft 80, as best seen in FIG. 6. Sheave 144 is integral with a larger sheave 145 driven by belt 147 trained over sheave 89 integral with the end of sheave 88. This arrangement is for the purpose of reducing the speed of reciprocation of carriage 14. The belt 142 passes over vertical sheaves 146 securedV to a bracket structure 148 of the carriage as best seen in FIG. 5.
In operation, when it is desired to fold the strip material and package it in the cartons or containers 66 which are disposed on the carriage 14, the strip material is delivered from a cutting machine not forming part of the invention. In the presentcase there are three strips or ribbons which are fed as illustrated in the drawings through the guide arms |130and over the slatted drum 50 and thereafter passed downwardly between the pairs of rollers '76 on each of the swinging arms 70.
The machine motor 30 is set into operation and it drives the driven shaft 38 through the belted drive 42 and the driven shaft 38 in turn drives the carriage shaft 80 through the belt drive 84, FIG. 6. The carriage driven shaft 80 in turn drives the eccentric sheaves 88 through the continuous belt drive 102 so as to cause the Pitman arms 96 to rock orswing the arms 70 back and forth, as illustrated in IFIG. 5, from one side to the other side of the platform |64- so that the strips of ribbon or material 12S-are folded back and forth into the containers. The belt drives -106 also cause the opposed pairs of rollers 76 to pull the strips of material therebetween and down into the containers. As the strips of material are folded back and forth from side to side of the containers 66, the horizontal eccentric sheave 134 is driven through the belt drive 142 from the driven shaft 80 so as to cause its eccentric pin 140 to reciprocate back and forth transversely of the fixed frame 12 between the parallel angle irons 26 to reciprocate the carriage 14 longitudinally of the frame 12 with the rollers 24 rolling along the angle irons 22 of the frame. This causes the ribbon that is being folded back and forth from side to side in the box to also be laid from one end to the other end of the box so that successive layers of ribbon are superimposed or stacked upon each other until the container is lled. The fork structure 58, FIGS. 2 and 7, which is secured to the carriage will move the sheave 54 along the shaft 38 and the'key 56 as the carriage moves or reciprocates back and forth with respect to the frame.
Thus, from the foregoing description, it is apparent that the present invention provides a machine for folding and packaging strips of endless material into containers in which the frame is stationary and a sliding carriage is provided for movement along .the fixed frame so that the ribbon is properly folded back and forth upon itself from side to side as it is laid into the container and individual layers of ribbon are deposited in the container from one end of the box to the other end until the box is completely lled.
The present invention further provides a novel common drive means for both reciprocating the carriage back 6 and forth longitudinally of the fixed frame as well as providing a drive means for swinging a plurality of swinging arms from side to side of transversely of the moving carriage while the moving carriage moves in a direction perpendicular to the movement of the swinging arms.
From the foregoing description it is also apparent that the present invention provides a novel means of reciprocating a moving carriage in a longitudinal direction along a xed frame by the use of a substantially horizontally disposed eccentric sheave which travels between spaced parallel guide members disposed transversely of the movement of the movable carriage in the device.
Furthermore, it is apparent from the foregoing descrip tion that the present invention provides a drive means for 15 a swinging arm in which the swinging arm is operatively connected to a Pitman arm andan eccentric sheave member and in which the swinging arm is provided with a pair of oppositely disposed rollers and in which a single continuous belt means drives the swing arm as well as the opposed rollers and is carried by the eccentric sheave member and a driven sheave member.
