PRIOR ART This invention is an extension of the developments of the tray loader of U.S. Pat. No. 3,290,859, dated Dec. 13, 1966 and the Richard C. Talbot application for patent for Converger and Feeder for Cookies for Wrapping", Ser. No. 74,4l8, filed Sept. 22, I970, now U.S. Pat. No. 3,627,l02 which patent and application are assigned to the assignee of the present invention.

SUMMARY, ADVANTAGES AND OBJECTS OF THE INVENTION Cookies are transferred from the sandwich machine and grouped in slugs of a preselected number of cookies in each slug, and delivered to a transfer conveyor transferring a plurality of slugs in side-by-side relation along drop gates disposed over a drop chute, converging the cookies for delivery to a slug conveyor, and depositing a slug of cookies between each pair of flights of the slug conveyor in a continuous operation. The transfer conveyor is driven in dwells and the drop gates of the slug conveyor open during each dwell and deposit the cookies into a drop chute which converges the groups of slugs and drops the slugs between the flights of the slug conveyor. The slug conveyor carries the slugs of cookies for deposit into from one to six bagging stations and delivers the cookies to the selected bagging stations through drop chutes, operable to drop the cookies into side-by-side troughs corresponding to the number of slugs delivered. A slug pusher operating in timed relation with respect to the dropping of cookies to the bagging station drop chute, pushes the cookies along converging troughs fitting into the mouths of bags extending along the troughs. The completion of pushing the cookies into the bag may be a manual operations, after which the bags may be heat-sealed by a machine separate from the bagging machine. The drop gates of the slug conveyor open to deliver the slugs to the bagging stations in staggered relation with respect to each other, to balance the load on the machine. As for example, where six bagging stations are in use, the slugs may be dropped into stations four, five, two, six, three and one or in any other preselected order.

The bagging stations are spaced along opposite sides of the slug conveyor and separate jack shafts are provided for the bagging stations at each side of the machine. Change speed gearing is provided in the drive to the jack shafts to drive the jack shafts at speeds corresponding to the groups of slugs to be bagged, and independent phase selector drives are provided between the jack shafts and the bagging stations, and drive individual cams and cranks at each station controlling dropping of the slugs of cookies from he slug conveyor,

dropping the slugs of cookies from the drop chute into the bagging trough and the operation of pushing the cookies along the bagging trough into the bag. The timing of the dropping of cookies from the slug conveyor, the dropping of the cookies from the drop chute to the delivery trough, and the pushing of the cookies may be varied at each bagging station through the positioning of the cams by the phase selector drives in accordance with the number of groups of slugs to be bagged and the selected number of stations to be operated, to assure the continuous dropping of the cookies from the lug conveyor to the preselected bagging stations with no piling up or spilling of cookies, or gaps or interruptions in filling of the slug conveyor and the bagging of cookies at the preselected bagging stations.

An advantage of the present invention is that articles, such as cookies may be bagged in a more efficient and expeditious manner than formerly in any number of series of bagging stations, delivering the articles for bagging in a preselected order.

Another advantage of the invention is that the drive to the slug conveyor, the drop gates for the slug conveyor and the drop gates dropping cookies to the bagging station are fixed to operate in timed relation with respect to each other, so the release of slugs from the slug conveyor will be at the proper timed intervals to fill the drop chutes and troughs at the bagging stations in a continuous operation during the entire bagging operation.

A further advantage of the invention is that individual controls controlling the dropping of slugs from the slug conveyor, the dropping of slugs from the drop chute into the bagging troughs and the pushing of cookies along the chutes into the bags at each bagging station are so operated as to enable the disconnection or connection of any bagging station at the selection of the operator of the machine.

Still another advantage of the invention is the provision of a phase selector drive mechanism at each bagging station, driven in accordance with the speed of travel of the slug conveyor, attaining the release of slugs from the slug conveyor and drop chutes to the bagging station at the proper timed intervals, which phase selector drive may vary the phases of the operating parts of the apparatus in accordance with the number of articles to be loaded, the number of stations in use and the speed of travel of the slug conveyor to keep the dropping and pushing operations in phase with travel of the slug conveyor in a simple operation by the operator of the machine.

A principal object of the invention, therefor is to provide an improved form of apparatus for bagging articles, such as cookies at a plurality of bagging stations, at any one of a number of preselected stations in a simple and expeditious manner, assuring no interruption in the bagging or packaging of the articles.

Other objects, features and advantages of the invention will be readily apparent from the following description of certain preferred embodiments thereof, taken in conjunction with the accompanying drawings, although variations and modifications may be effected without departing from the spirit and scope of the novel concepts of the disclosure.

MACHINE IN GENERAL AND TRANSFER TO SLUG CONVEYOR In FIG. 1 of the drawings, we have diagrammatically shown in plan, a conveyor 10 conveying cookies from a bake oven (not shown). The cookies are taken by hand from the conveyor 10 and transferred to side-by-side vibratory feeder troughs I l on one side of the conveyor, and into the vibratory feeder troughs 12 on the opposite side of the conveyor 10, and fed to a sandwich machine 13 coating the cookies with cream and making the cookies into sandwiches in a manner similar to that shown and described in US Pat. No. 2,936,557, so not herein shown or described further.

From the sandwich machine, the sandwiched cookies are transferred in rows, herein shown as being in four rows, to a counting conveyor 15, separating the rows of cookies into slugs of a preselected number and delivering the slugs in side-by-side relation to a transfer conveyor 16. The transfer conveyor 16 transfers the cookies along drop gates 17 (FIG. 4), which are movable to release the slugs of cookies to the space between the flights of a slug conveyor 19, in timed relation with respect to travel of the slug conveyor, to fill the space between each flight of the slug conveyor upon traveling movement thereof. The counting conveyor, transfer conveyor and drop gates are shown and described in US. Pat. No. 3,290,859, so need not herein be shown or described, except insofar as the transfer conveyor and drop gates cooperate to continuously fill the flights
