MAGAZINE PREFERABLY FOR PACKING BLANKS

Abstract: A magazine, preferably for packing blanks, and including an underlying support surface (3, 4), as well as means for advancing the blanks forwards to a blank picking device (6). The means for advancing the blanks (2) forwards towards the blank picking device (6) comprises a vibrator (5) rigidly mounted at the support surface (3, 4) carrying the blanks (2), said vibrator being adapted to vibrate the support surface (3, 4) simultaneously as it is inclined towards the blank picking device (6) such as to form an angle which is between 1-10<o> to the horizontal plane, advancing of the blanks (2) being provided without the latter needing to be acted on by any other support or advancing means.

Description: MA H INE PREFERABLY FOR PACK ING BLANKS The present invention relates to an apparatus in magazines, preferably for packing blanks, and which includes an underlying support surface and means for thrusting the blanks forward to a blank picking device. Known magazines work with an angle of from 10° and more, with movable magazine rods in the bottom to reduce friction against the blanks. Weights of different configurations are used to thrust the blanks forward and to prevent them from falling backwards. There are also horizontal magazines or magazines with a small angle. These work with driven, underlying conveyor means and with weights placed behind the blanks. The present invention has the object of providing a new type of magazine in which the disadvantages to be found in known structures have been eliminated, and which is simple in its implementation and cheap in manufacture. Essentially distinguishing for the invention is that the means for thrusting the blanks forwards towards a blank picking device constitutes a vibrator rigidly mounted on the support surface carrying the blanks, and which is adapted to vibrate the support surface simultaneously as the latter is inclined towards the blank picking device such as to form an angle attaining to between 1-10° to the horizontal plane, advance of the blanks being provided without these having any further support or advancing means. With the aid of the invention there is thus provided a magazine which is easier to fill with packing blanks than previously, easier to re-adjust to different packing blank formats and with which a change of blank can be carried out considerably more quickly than previously. By using the vibrataor, mountings at both ends of the underlying support surface are avoided, these being otherwise necessary in previously known structures. This gives a considerably simpler and cheaper magazine structure. With the invention there is also obtained the advantage that the pres-sure of the blanks against the blank picking device is considerably less than in previous structures, which facilitates picking the blank, and results in that two blanks will not be picked at one time, precisely due to the fact that the pressure between the blanks is considerably less than in previously known magazines. Advancing the blanks in accordance with the invention is provided solely by the vibration of the underlying rods. No weights behind the blanks are needed to prevent them falling, unless the blanks are not flat. The invention will now be described in detail below with reference to the accompanying drawing, on which Fig. 1 is a schematic side view of a magazine in accordance with the invention, and Fig. 2 is a schematic end view of the magazine illustrated in Fig. 1. As will be seen from the drawing, the magazine 1 in accordance with the invention comprises two underlying, support rods 3, 4 having at their free ends 8 a rigidly mounted vibrator 5. At their opposite ends 9 the rods 3, 4 are fixed to a frame 7, adjacent a blank picking device 6. The frame 7 is also provided with two side rods 10, 11 spaced upwards of the rods 3, 4 and substantially parallel thereto, these rods being intended to support the blanks 2 laterally. The rods 3,- 4 incline in a direction towards the frame 7, which has the blank picking device 6 in the vicinity of its side facing away from the rods, which also form an angle of between 1-10° and preferably 2-6° to the horizontal plane. When the vibrator 5 is energized, the blanks 2 are advanced towards the blank picking device 6 by the rods 3, 4 vibrating. This advance of the blanks 2 is thus achieved without them having any further support or advancing means.

Claims: CLAIMS 1. Apparatus in magazines, preferably for packing blanks (2) and including an underlying support surface (3, 4) and means (3-5) for advancing the blanks (2) forwards to a blank picking device (6) , characterized in that the packing blanks (2) are situated tightly adjacent each other with their respective end edge portions engaging directly against the support surface (3, 4) and such that the last, outmost blank in the bunch is free and engages with its own .weight against the blank in front of it without the use of supporting or advancing means, and in that the means for advancing the blanks forwards towards the blank picking device (6) comprises a vibrator (5) , known per se, and rigidly mounted to the support surface (3, 4) carrying the blanks (2) , the vibrator being adapted to vibrate the support surface (3, 4) simultaneously as this surface is inclined towards the blank picking device (6) such as to form an angle to the horizontal plane which is between 1-10°, advancing of the blanks (2) being provided without the latter needing to be acted on by any other support or advancing means. 2. Apparatus as claimed in claim 1, characterized in that the vibrating support surface (3, 4) for the blanks (2) forms an angle of 2-6° to the horizontal plane. 3. Apparatus as claimed in claim 1, characterized in that the support surface comprises at least two mutually parallel rods (3, 4). 4. Apparatus as claimed in any one of the preceding claims, characterized in that the rods (3, 4) are fixed at one end (9) to a frame (7) in the vicinity of the blank picking device (6) as well as having a free end (8) , where the vibrator (5) is mounted.
