BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an adjustable magazine apparatus in a machine for forming box or carton blanks and the like, the magazine including bottom and lateral side guides movably adjustable for enabling the use of different size blank formats. The present invention further relates to means for advancing the blanks forward in the magazine toward the exit or delivery end. Related subject matter is set forth in copending U.S. application Ser. No. 07/689,760 filed May 29, 1991.
2. Description of the Related Art
A variety of types of feed means in magazines for feeding blanks are well known. However, these magazines have complicated arrangements for feeding the blanks forward. In addition, problems often arise when blanks become packed together at the delivery end of the machine. When this occurs the blanks stick one against the other, preventing one at a time conveyance to an erecting tool, resulting in machine downtime. Another problem with these types of magazines has been that different size magazines are required for different blank formats. Moreover, in the case where a magazine is adjustable for different blank formats, the adjustment is very time consuming and complicated.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an apparatus whereby the adjustment of the magazine to different blank formats can be carried out very simply, and in which the disadvantages to be found in known magazines on the market have been eliminated. What is essentially distinguishing for the invention here is that the magazine tool details which carry the lateral and bottom guides are movably adjustable relative to each other with the aid of format setting wheels to suit a plurality of predetermined blank formats. The format setting wheels have the same number of pins as the number of desired formats. Each pin length corresponds to one of the dimensions of the predetermined blank format. The end surfaces of the pins are adapted for coaction with stops on the respective tool detail, to fix the detail in the position determined by the chosen format.
With the aid of the present invention, there has now been provided an apparatus in a magazine which, apart from its being simple and inexpensive to manufacture, fills its function in an excellent way. With the aid of the inventive apparatus, the magazine can now be automatically set for different blank formats simply by the operator turning format selection knobs which in turn actuate the format setting wheels to provide the predetermined setting, a suitable number of formats being catered for by each format selection wheel.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described in more detail below with reference to the accompanying drawings, where
FIG. 1 is a schematic side view of a magazine in accordance with the present invention, and
FIG. 2 is an end view of the magazine illustrated in FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As will be seen from the drawings, the magazine 1 in the preferred embodiment of the present invention comprises bottom guides 2 and lateral guides 3 for blanks 4 arranged in the magazine 1. For advancing the blanks in the magazine 1 there is arranged at least one elongate means 5 between and closely adjacent the respective bottom guides 2. Means 5 is eccentrically mounted in the bottom guides 2 so as to temporarily project a short distance above the carrying surface of the bottom guides 2. This distance is sufficiently long enough to stepwise advance the blanks 4 into engagement with an end stop 6 at the delivery end 7 of the magazine 1. Driving the eccentrically mounted elongate means 5 is a motor 8 and shaft 9. The shaft 9 is provided with wheels 12 fixed thereon, the wheels being in turn provided with fixed short shaft 11. The projecting parts of the shafts are mounted in bearings 10 on the elongate means 5.
In connection with the end stop 6 there is a contact breaker, preferably in the form of a photo cell 13 arranged to se
