(Cl. 194-4) The present invention relates to an improved apparatus for receiving, assorting and storing of returned empty bottles for milk, refreshing drinks and the like in shops and stores in order to free the employees from this work and improve the selling service.
One object of the invention is to provide a fully automatic-working bottle-receiving apparatus effecting a matching and separation of bottles of diderent sizes.
Another object of the invention is to provide a fully automatic-working bottle-receiving apparatus assorting and distributing bottles of different sizes to different storing places. l Y
' A further object of the invention is to provide a fully automatic-working bottle-receiving apparatus comprising a receipt-delivering device.
With these and other objects in view the invention essentially consists in an apparatus for receiving, assorting and storing of returned empty bottles, comprising a guiding path for the movement of the bottles from an intake end of the guiding path to alternative stop places for bottles of different diameters in compartments arranged successively in line after each other along the path, each compartment except the last one having an opening in the rear end for free passage of bottles with smaller diameter than the certain bottle which is intended to be retained in the compartment, each compartment containing a stopper for the certain bottle, an outlet opening in the path, a blocking shutter in the opening, a catch rfor the shutter, releasing means for the shutter permitting in dependence of the stop position of the certain bottle a slipping off of the bottle through the outlet opening on its way to a storing place.
In the accompanying drawings:

FIGURE 8 is a diagram of an acceptable conventional circuit for the apparatus.
v In the embodiment shown in the drawings the bottlereceiving apparatus comprises a housing provided With a -guide path 1 in the shape, for instance, of a channel or trough with an intake end 2 for bottles 3a, 3c of different diameters and usually also of diiierent length, the bottles Ibeing inserted in lying position through the intake with their bottom preferably foremost. The construction of .the channel is comparatively simple `and easy to understand. At the intake end 2 the channel 1 has the shape of FIG. 1A with solid side Walls lx, 1y. In the chambers la-lc the side wall 1y is broken away torpermit the bottle to roll out laterally. Of the Wall 1y there is left nonly a small portion 35 for stiiening purposes, and this bandportion must be narrow as seen in FIG. 4, so that there is no hindrance for the bottle to roll out. To Yindicate that here is an outlet for the bottles this portion in FIG. l of the drawing is indicated with dashed and dotted lines.
The channel is illustrated as containing three receiving' compartments la, lb, lc--although any number may be used-in line with each other for receiving empty bottles, for instance milland cream-bottles, of dilerent diameters with the largest bottle destined for the first compartment 1a next to the intake and the smallest bottle for the compartment 1c most remote from said intake. The channel has such an inclination downwards from the intake that the bottles will, because of their weight, slide down along the oor or bottom 4 of the channel. The two compartments la, 1b are at their rear ends provided with openings limited by upper cross members or beams 5a, 5b disposed at a predetermined height above the bottom of the channel that the particular size bottle destined for one of these compartments cannot pass the cross member or beam, which however will permit bottles of smaller diameters to slide on to their afterlying intended compartments. lf lc designates the last compartment in the row au end member 5c defining the bottom of the apparatus is substituted for the cross beam. At each cross beam as well as at the end member 5c there is provided for the bottle a stop member in the shape, for instance, of a push button 6a, 6b, 6c serving at the same time as a switch for an electric circuit, not shown, to be actuated yby the bottom of the corresponding bottle when it arrives at the respective stop position. In each compartment, the walls of which are supported by an iron band 35, there is an outlet opening for the bottle in the bottom and side wall of the channel or trough 1 and designated 7a for the compartment la, as well as 7c for the last compartment lc, extending towards the center line of the channel bottom, where a pivotable shutter 8 for the opening is arranged and is balanced by a weight. This shutter is in its closing position locked by a catch 9 to be actuated by an electromagnet lil in circuit with the corresponding push button switch 6a. When for instance the switch 6a is closed by an arriving bottle 3a the corresponding magnet l@ will withdraw the catch 9, and the bottle will roll out laterally on laterally directed guide rails 11, 12 and drop down upon a transport conveyor or band 15a or any other suitable remover. Such conveyors 15b and lSc are also provided for the remaining compartments. For the compartments la and 1b the guide rail 12 near the rear end or" the compartment is shorter than the other rail 11, on account of which the bottle, upon arriving at the end of the shorter rail 12, will tip to an upright position and remain in such position on the conveyor. For the smallest bottle 3c, for instance a cream bottle, disposed in the last compartment 1c the rail llc, which is longer than` the rail 12C, is lying next to the rear end of the apparatus and the bottle will tip to its inverted position. The bottle slides in this position along a slide or channel into a stop corner 14, where the bottle will tip back-wards over an edge of an opening and drop in its upright position upon the conveyor 15C. The reason for this arrangement is that the diameter ofthe cream bottles is usually substantially smiliar to the diameter of longer bottles used for refreshing drinks, so that the last compartment is able to be used also for such bottles. For these bottles there is a further and still longer rail 13o which is positioned furthest om the rear end of the compartment and the longer bottle will roll out on the rails 11e, 13e and tip directly to upright state upon the conveyor, the underlying channel for the sh-orter bottle being temporarily removed.
The apparatus is further provided with a device 16 for delivering receipt disks or tickets. In the embodiment esagera shownv in FIGURES Gand 7"thisd'evice'is-provided with two stack of disks 17a, 17h, the lirst one for the simul taneous delivering of two disks corresponding to the value ofthe greatest bottle, and the'otherv stack for the deliveringjof single' disks` for smaller bottles. Beneath each stack thereis4 a catch vslide Ln, lh for corresponding numberof disks, each slide being connected to' a swingable slide-actuatingarm 19a, l9b to push the slide to a disk-catching position and then back to a disk-delivering position over a vdiskatransporting tube 2d, from which the'customerzcanpiclcup the disk or disks. The arms are lyingl between electromagnets, the arm 19a between the magnetsl 21a, 2lb, and the arm 19h betweenk the magnets 22a, 2,211 whereby the magnets Zia, 22a cause the movement for 'disk catching, and the magnets 2lb, 22]; lthe arm movement` for disk delivering. The magnets 2in, 22a' for the diskfcatching movement are included in the electric circuit ofa` switch 23, the closing of which by a swingable contact ar1n-25 is dependent on the opening movement of a movable member or swingable flap 27 in the intake end openingof the channel i. Said Hap is swung' to open position by the bottle as this is inserted into the channel, and an arm 2o attached to the ap knocks against said contact arm 25 and thereby closes the circuicof the switch 23 with the result that both the catch `slides 13a, 13b are drawn into` position beneathV the disk stacks, theorie slide catching two disks and the other slide one. disk.
The circuitrytor the apparatus is seen in FIGURE 8 "and' is; explained as follows:
"Vhen albfottle is inserted the flap 27 at the entrance isswung open and the'connected arm 26 closes the switch 23. The current from the line A passes through the line 'C'andrthrough` the magnet coils 21a, 22a to the O-line D. Thema'gnets draw the slideslta, lsb to the stacks 17a,
tl'iatdrives'the slide ldb with the sole disk to the outlet opening permitting' the disk to fall out.
At the same time, the correspondingl lock for the bottom shutter in the corresponding compartment for the bottle is released by energizing the corresponding magnet 1t), through ,whichthe current passes to the O-line. Also the current through the magnetcoil ZZ passesto the O-line or' to earth.
The contact arm 25 will also serve as a circuit closer for a switch 24 at the returning movement of Lheliep,
the arm 2o of'wliichwill again knock the contact arm 25 fand switch it over to said switch 24. The electric circuit vof'ithis` switch includes the two magnets 2lb and 22h for the back pushing of the'slides to disk delivery positions.
vHowever, as the disk or disks from one stack only are to be let free the magnets last mentioned are placed in devpendencefon the `compartment switches tic, ob, 6c in such a wayA that the switch da actuated by the greatest bottle 'is' in circuit connection with the magnet 2lb for delivery fof: two disks, and the two otherv compartment switches 6b, 6c" actuated by the smaller bottles in circuit connecltion with the magnet Zib for'delivery of one diskonly. Thusthe two disksfor the greatest'bottle are delivered if both the compartment switch 6a and theswitch 24 are simultaneously in closing position, and one disk will be delivered .for the smaller bottles if any of the compartrment switches 6b, 6c and the switch 24 are simultaneously in closing position. A result of this is that no disks are delivered. if theflap is opened and closed by a bottle which.istheri-.redrawn by the customer.
By the apparatus and device described above empty 4 r bottle are received, assorted and delivered. in accordance with their respective size to diierent storing places and the customer receives a receipt at the same time. Thus the customer always has proof for each empty bottle he has returned and can use-this' upon buying a new full bottle.
In the drawings and specification.. there has been set forth a preferred embodiment of the. invention, andalthough specic terms are employed, they are used in" a generic and descriptive sense only and not for purposes of limitations, the scope ofthe invention being defined in the claims.
