Definitions

  • This invention relates to an apparatus for packaging novelty articles, and particularly articles such as of a confection of the popsicle type. It is a common practice to package popsicles by hand. Said popsicles after being formed are generally individually inserted into envelopes and then certain numbers of these are packed into containers. This two-step hand packing operation is a relatively slow one and results in a relatively high unit handling cost. It is desirable therefore to have an apparatus adapted to automatically perform the otherwise manual operations of receiving and packaging popsicles to increase the rate of handling speed, to reduce the unit handling cost and to improve the sanitation conditions of handling the confection by having the confection completely free from human or hand handling.

Dotzenroth, deceased. assignors to Baker Engineering Corp., Minneapolis, Minn., a corporation of Minnesota Filed May 16, 1969. 'Ser. No. 29,353 8 Claims. (Cl. 53-471) This invention relates to an apparatus for packaging novelty articles, and particularly articles such as of a confection of the popsicle type. It is a common practice to package popsicles by hand. Said popsicles after being formed are generally individually inserted into envelopes and then certain numbers of these are packed into containers. This two-step hand packing operation is a relatively slow one and results in a relatively high unit handling cost. It is desirable therefore to have an apparatus adapted to automatically perform the otherwise manual operations of receiving and packaging popsicles to increase the rate of handling speed, to reduce the unit handling cost and to improve the sanitation conditions of handling the confection by having the confection completely free from human or hand handling.
It is an object of this invention therefore to provide an apparatus for automatically receiving, handling and packaging a confection such as a popsicle.
It is another object of this invention to provide an apparatus adapted to receive a continuous supply of popsicles, to respectively place the same into individual envelopes and to place or pack predetermined numbers of said popsicles into containers or packing cartons.
It is a more specific object of this invention to provide an apparatus for receiving a continuous supply of popsicles and to be supplied with envelopes, to position and open said envelopes to respectively receive said popsicles, to place said popsicles individually respectively into said envelopes, and to place predetermined numbers of said popsicles into packing cartons or containers and to position said popsicles in said cartons or containers.
These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:

Mounted at the outer end portion of said shelf 375 in longitudinally spaced relation are bearing blocks 380 and 381 respectively having shafts 382 and the outer end of shaft 365 jou-rnaled therein with said shafts having mounted thereon sprockets 385 and 386 having a chain 387 pass thereover. Mounted on said shelf 375 in longitudinal alinement with said chain 387 and suitably supported thereon is an air cylinder 390 having air hoses 392 and 393 respectively communicating with the ends thereof and having a piston 395 adapted to extend forwardly between said bearing blocks 380 and 381 and carrying at its free end a sliding block 397. Carried on said block 397 is a hook-like member 398 adapted to be depressed to engage the chain 387 to move the same to the right, as viewed in P16. 2, when the cylinder 395 is moved to the right and adapted to be raised out of engagement with said chain when moved to the left. This is a commonly used construct-ion and it is not believed further detail is necessary.
Said hoses 392 and 393 are respectively secured to an air control valve 287 which will be connected to the air compressor 48. Said air valve 287 has an arm 287a actuated by a earn 290 secured to a shaft 291 journaled in a bracket 292, which bracket is secured to the gear box 120, and carried on said shaft 291 is a sprocket 295 driven by a chain 296 passing over a sprocket 298 secured to shaft 112. Said air valve is of a two-way type in common usage which will alternately deliver air pressure to the hoses 392 and 393 which are connected to diiferent ends of the cylinder 390 to reciprocate the piston 395.
Operation In operation, the meter box 88 will be charged or filled with popsicles 95 by a suitable conveying means, which means forms no part of the present invention. In the embodiment of the invention here disclosed, the meter box is adapted to hold twenty-four popsicles in transverse rows of six which are discharged in cycles of six on a row at a time. The plate member 96 forms a bottom cover for said meter box, and formed in said plate member is the transversely extending slot 96a through which said rows of said popsicles drop through as said rows come into alinement with said slot. Said meter box is moved forwardly by action of the arm 102 being reciprocated by the inner side cam track 126 of the cam 125.
A supply of bags 153 are loaded into the slots 141 with the weights 156 applying pressure therebehind and being retained in position by the depending portion of plate 134 and the upstanding flange 146a. The front portions of said bags 153 are cut to be somewhat lower than the rear sides. Mounted in connection with the plate 138 are hose members 200 disposed through said plate in alinement with each of said slots 141 and being positioned somewhat above the upper edge portions of said bag-s 153. Said hoses 200 are connected to the manifold 253 and from thence by hose 290 with the impeller 292 which will be continuously operated to provide a substantial volume of low pressure air to continually blow against the upper edge portions of the bags 153 through the inverted U notches 134a. The air will have suflicient pressure to enter at the front edge portion of the bags and inflate the bags to pull said front edge portion away from the restraining effect of the member 134 to the position indicated in FIG. 8.
The popsicles dropping down from said meter box 88 will respectively drop into the open bags alined therewith and positioned therebelow, and said popsicles will be guided at each side by the guide members 134 When the popsicles come into the bags they do so with sufiicient force to spread the bottom edge portions of the bags sufficiently to urge them out of engagement with the flexible flange 146a and to cause the bags to drop downwardly to be supported on the ledge 160, as indicated in FIG. 9, with the bags being inclined against the supporting rod 56a. In its initial position said ledge 160 will be in a horizontal position. Said ledge 160 through linkage connected therewith and in connection with shaft 172 and arm 182 is actuated by the cam follower 184 in connection with the cam track 19011 of the cam 190. Said ledge 160 will be cycled in its movement to coincide with the forward movement of the meter box 88 to provide support for each row of popsicles filling said b ags 153 to have said row of bags evenly alined before going on to the next step.
Said rows of popsicles are respectively dropped with the withdrawal of the ledge 160 onto the slide formed by the flipper members 215.
The rotation of the turntable 42 will be cycled to be in harmony with the movement of the popsicles whereby said tray units 230 will be positioned, as indicated in FIGS. 1 and 5, to receive a row of said popsicles as they are guided downwardly by the flippers 215. Each of the trays of the tray unit 230 will first receive three popsicles positioned in trays 231 and 232 respectively, as indicated in- FIG. 12. The popsicles hit the leading edge of the trays and fall rearwardly with their stems in the direction of the opposite ends of the trays. As said ledge is moved to release the popsicles, the arm 166 actuates the valve 319 which releases air pressure to actuate the arm 300 and the prongs 301 to extend upwardly into said trays at the rear of the popsicles to hold the same in position.
Said tray unit 230 will remain in position until the next row of popsicles is dropped and the flipper 215 will be reversely inclined oppositely the direction in which it is indicated as being inclined in FIG. 9, and will be turned by connecting structure through the action of the cam 189 having the cam follower 2241) moving in the cam track 189a whereby the second row of popsicles to come into the tray unit 230 will be positioned oppositely of the popsicles shown in 212 with the handles a respectively being in overlapping position. Said turntable 42 as rotated by the Geneva gear 325 will then rotate at intervals of ninety degrees bringing a new tray unit 230 into position to be loaded with each movement. When the turntable 42 has turned 180 degrees the first loaded tray unit will be in a forward position, as indicated in FIG. 5.
The conveyor structure 350 will be positioned and timed to have containers thereon moved into position to be in vertical alinement with the loaded trays 230 ready to receive popsicles therefrom. As a tray 230 in loaded condition is positioned above the containers 374, the knob 233 will move into engagement with the lower forwardly extending split arm portion of the arm 265, and at this instant said arm will be released by the cam 123 and swung to a rearward position by action of the spring 283 to witlidraw rearwardly the bottom curtain 234 from the tray unit 230. Timed with the action of the withdrawal of the curtain 234 is the action of the plungers 235' and 236, which through connecting linkage will be released by the cam 127 to fall by gravity urged somewhat by the action of the springs 237 to move downwardly with the popsicles as they drop through to the containers 374 to position and closely pack the popsicles in said containers. The conveyor belt may be timed so that the containers thereon may respectively receive any predetermined numbers or layers of popsicles as may be desired. The conveyor is moved by the reciprocal action of the air cylinder 390 which is operated by compressed air controlled through the hoses 392 and 393 in connection with the air valve 287 and the compressor 48.
The containers 374 will be unloaded from the conveyor structure 350 in any desired manner.
Thus it is seen that I have provided, a compact, nicely coordinated popsicle packaging apparatus carefully adapted for and proved to be efficient in operation and is timed to handle normally 1200 popsicles per minute. This handling removes the popsicles from any contact by human hands and provides an efiicient low cost per unit and sanitary packaging operation.
