The chute is closed from below by a pivotal element which supports the stack. A spring pivotal with the element has a portion extending over the front of the element to engage and support the penultimate article in the stack when the element is pivoted to discharge the lowermost article of the stack.

4 Claims, 3 Drawing Figures PATENTEU IARZS I974 SHEU 2 UP 3 PArEme-nmzsm 37993-94 SHEET 3 OF 3 FLT-3 DEVICES FOR DISPENSING ARTICLES FROM A STACK OF ARTICLES BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to devices for dispensing articles.
2. Description of the Prior Art A device for delivering pre-packed articles from a vertical stack within a vertical chute has been proposed in which the chute is adjustable at least in width relative to the width of the articles, and the articles are fed downwardly towards an outlet closable by means of a bottom element capable of pivoting downwardly about an axis extending in the direction of a lateral edge of the articles. The bottom element is upwardly inclined so that when the element is in its closed position, the lowermost article in the stack is offset slightly relative to the penultimate article. When the element is pivoted, the upwardly inclined portion of the latter, supports the penultimate article of the stack, whilst an arrester element engages the stack sliding in the chute and prevents the remainder of the articles of the stack from tumbling above the bearing surface constituted by the portion of the bottom element.
The dispensing device, driven by purely mechanical or electronic means or by an electric motor, is preferably activated by an operating lever.
This dispensing device, however, fails to provide sufficient support for the articles located above the article to be dispensed and that, under certain conditions, several articles may be delivered during the course of movement of the bottom element.
SUMMARY or THE INVENTION According to the present invention, there is provided in a device for dispensing articles, a vertical chute for a stack of articles, a pivotal bottom closure element for the chute, the element having an upwardly directed portion, said upwardly directed portion supporting the penultimate article of thestack during discharge of the lowermost article in the stack, first spring means at the front of the element, said spring means having a portion engaging the upwardly directed portion of the element and defining an article-discharge passage to the rear of the element, and second spring means, said second spring means extending into the passage and engaging the stack.
Preferably, a slide member of comb-like form is located at the outlet of the device, which member is operated by an operating lever of the element to block the outlet whereby the articles are delivered singly.
BRIEF DESCRIPTION OF- THE DRAWINGS ele- DESCRIPTION OF THE PREFERRED EMBODIMENT on a bottom wall or element 3 of the chute, the wall 3 being mounted pivotably on a shaft 4 extending in the direction of a lateral edge of said articles.
The edge portion of the wall 3 adjacent to the shaft 4 is inclined upwardly to form a double-front wall 5.
On the shaft 4 there is mounted a coil spring 6; the opposite end portions 7, 7a of the spring 6 bear against the wall 3 and a central portion of the spring 6 is in the form of a loop 8 shaped to engage the front wall 5. The upper edge 9 of the loop 8 forms a support element for the penultimate article 2b in the stack, when the wall 3 is tilted by means of an operating lever 26 in the direction of the arrow A to effect withdrawal of article 2a.
In the interior of the chute 1, there is provided, in the region of the rear wall of the chute, a guide plate 10, an upper, folded-back end portion of which is attached to the wall of the chute and the lower end portion of which is movable by adjusting means (not shown), in
accordance with the depth of the articles handled.
The lower end portion of the guide plate 10 (FIGS. 1 and 3) has a folded-back portion 11, which, together with the rear end edge portion of the wall 3, defines a passage 12 for the articles when the wall 3 is tilted.
During the tilting of the wall 3 in the direction of arrow A to effect withdrawal of the article 2a, the arms 15, 15a of the spring 14 are freed from engagement with the article 2a, and move into a position underneath the penultimate article 2b, so as to support the latter in conjunction with the upper edge 9 of the loop 8 of thespring 6, whereby to prevent the article 2b from entering the passage 12. The spring 6and 14 act, in effect, to prevent tilting of the article 2b into the pas sage 12 which is open during the delivery of the article 211. Y
The lower side walls 17 of the chute carry a bottom wall 18, which supports a slide member 19, capable of closing, in the extended position indicated by broken lines, a passage outlet 20 for article 20. The slide member 19 has two vertical lugs 21 with apertures 22 in which there is slidable a shaft 23 of a lever 24 pivotable about a shaft 25 on the side walls 17 of the chute l.
On its upper portion, the lever 24 has an elongate recess 27, in which the operating lever 26 is slidable, the lever 26 being rigid with the wall 3. When the wall 3 is in its horizontal position, the slide member 19 is in its retracted position to permit the article to be discharged through the outlet.
When the wall 3 is tilted in the direction of the arrow A by means of the lever 26, the lever 24, is caused by lever 26 to pivot about the shaft 25 and moves the slide member 19 by means of the shaft 23. The member 19 thus blocks the opening of the passage during discharge of the article 2a, and retains the article; when the wall 3 is returned to its horizontal position, the
