Definitions
- the invention relates to a method for the consecutive feeding of flat articles, in particular envelopes, via a conveying path from a first stacked arrangement to a second one with a lower height, for producing an appropriate position of the articles on a machine that processes them, the articles being fed in a scale-like manner offset from one another by deflecting the conveying flow to the underside of the second stacked arrangement.
- the invention also relates to a device for carrying out the method with an inclined storage table with two mutually perpendicular support surfaces for the stacked reception of the flat articles and with a conveyor line which moves from the storage table to a removal area of a flat article Machine extends, the conveying path having a deflection and a region of the support surface of the supply table, which is intended to support a surface of an article, being formed by part of the conveying path.
- this object is achieved in that the first stacked arrangement is formed with the articles oriented upright and the removal from this first arrangement by engagement of at least one conveying member with the upper edge of the respective article and movement to a subsequent one
- the conveyor line takes place, a device supporting the relevant envelope opening the conveyor path for it.
- a device is proposed which, according to the invention, is characterized in that the part of the conveying section provided on the supply table has at least one conveying member intended for engagement with the upper edge of an article.
- FIG. 1 shows a reduced schematic representation of a device according to the invention in longitudinal section
- FIG. 2 shows an enlarged partial view in the direction of the arrow II of FIG. 1, with two guide rollers of a belt conveyor and their storage,
- FIG. 3 shows a top view of the support surfaces of the storage table of the device according to FIG. 1,
- FIG. 5 shows a partial perspective view of a replaceable conveying device of the device according to FIG.
- the storage table 1 serves for the upright stacking of a large number of envelopes K or other flexible, flat articles.
- the envelopes are to be conveyed from the supply table 1 to the horizontally oriented end region 2 of the device, so that they assume a position there from which they can be lifted off by the suction pads S of a processing machine, for example a printing machine.
- the storage table 1 has a lower table top 4 which is inclined slightly downward, for example, by 22 ° in the removal direction, for supporting the lower edge of the envelopes K and a second, front short support plate 5 which, with the table top 4, has an angle of at least approximately 90 ° includes.
- a second, front short support plate 5 which, with the table top 4, has an angle of at least approximately 90 ° includes.
- an elongated conveying device 6 with a downwardly directed conveying direction, on which there are several conveying members 7 intended for engagement with the upper edge of the envelopes K.
- the foremost envelope in the removal direction of a stack provided on the storage table 1 rests on the support surface formed by the support plate 5 and the conveyor device 6. Because of the length of the conveyor device 6, which is designed, for example, as a conveyor belt, the device is suitable for envelopes of different sizes.
- the pressure with which the envelopes K rest on the support plate 5 and the conveying device 6 and with which the envelopes are conveyed on the table top 4 can be increased by a loosely placed sliding device 8 acting under the influence of gravity. This thus moves in accordance with the removal speed of the envelopes K, for example guided on rollers 3, on the table top 4 in the direction of the inclination.
- the rollers 3 are provided on a narrow side of the flat sliding device 8. For easy removal of the sliding device 8 in order to fill the storage table 1 with a new stack of the envelopes K, the latter has a handle 11.
- the conveying members 7 of the conveying device 6 consist, for example, of narrow ribs, which are attached or formed transversely to the surface of the conveyor belt 6. They can thus be formed as a profile of an endless conveyor belt consisting of rubber or plastic. Their spacing from one another determines the spacing of the envelopes K conveyed one behind the other or the extent of their mutual overlap, so that they form a scale-like conveying stream. For trouble-free conveying, the overlap width or the distance mentioned must be smaller than the width of the closing flap of the smallest envelope intended for processing measured in the same direction. This type of funding enables high funding speeds while maintaining a regular flow rate mutual overlap of the envelopes K according to the distance of the conveying members 7 from each other.
- the front support plate 5 is preferably set back slightly to the receiving space of the storage table 1, so that the front envelope K assumes an additional inclination directed towards the conveying members 7. This favors the secure engagement of the conveyor elements 7 with the upper edge of the envelopes, supported by the pressure of the sliding device 8.
- the support plate 5 is set back by the height of the engagement ribs 7 from a plane including the outer surface of the conveyor belt 6, so that a tangent placed on the engagement ribs 7 lies in the plane of the support surface of the support plate 5.
- the envelope After an initial area of an envelope K with its lower edge having the closing flap fold has passed the slot 9, the envelope is gripped between a deflecting roller 12 and a second conveyor belt 13 and conveyed further. From the forward inclined position on the storage table 1, the deflection of the conveyor track leads to the horizontally directed end region 2 of the conveyor track. The weather movement of the envelopes K is not shown Stop of the subsequent processing machine stopped, so that the 'scale-like following flow of the envelopes K builds a stack from below if the feed is faster than the removal by means of the suction elements S of the processing machine.
- the speed of the feed is preferably adjusted by adjusting the rotational speed of the drive motor 16 of the conveyor belts 6, 13 so that it is somewhat faster than the removal by the processing machine.
- a light barrier can be arranged above the end region 2 of the conveyor track, which generates a signal for switching off the drive motor 16 and for renewed, electronically delayed switching on when the stack has been removed is.
- a contact switch can also be provided, which is triggered by an upward movement of a pressure roller 17 resting on the conveying flow in the region of the end-side stack formation.
- the pressure roller 17 is mounted on a roller holder 19 which can be pivoted about an axis 18. In this way, no complex control is required by taking control signals from the processing machine.
- high delivery speeds are e.g. in the range of 12,000 to 15,000 envelopes per hour.
- the device does not require a floor stand, but because of its compact design it can be placed with its feet 20 directly on the feed table of a processing machine, for example a printing machine.
- the horizontal length of the device in the conveying direction when the table top 4 is removed is, for example, only 460 mm.
- the arrangement of the drive motor 16 in the front area of the device under the horizontal part of the conveyor line leads to an advantageous weight distribution in the device, so that it takes a stable position on the feed table of the processing machine without fastening means. For this purpose, the low amount of the whose area of the device is lowered.
- the drive motor 16 has a belt wheel 21 for two belt drives 22, 23, one of which extends forwards to a roller 24 of the conveyor belt 13 which limits the device forwards.
- the other belt drive 23 is used to drive the conveyor belt 6 carrying the engaging members 7.
- An additional belt drive 25 is interposed in order to achieve the correct direction of rotation, and both are in drive connection with one another via a pair of gearwheels 26, 27.
- the two upper guide rollers 29, 30 of the conveyor belt 13 are at both ends mounted on a slidably guided bearing plate 31. They are pressed against the deflecting roller 12 with the force of a tension spring 38 and, moreover, under the influence of gravity, in that the guidance of the bearing block formed from the bearing plates 31 and their connecting rod 37 is inclined downwards.
- this guide as shown in FIG. 2, there is a straight guide web 32 on the outside of each guide plate 31, which is held between two pairs of roller bearings 33, 34 arranged one behind the other.
- the lower support plate 4 of the supply table 1 is also on the
- the support plate 4 rests on a narrow side of the bearing plates 31, and at least one hook 36 provided on the underside of the support plate 4 engages under the connecting rod 37, which rigidly connects the two bearing plates 31 to one another to form the bearing block.
- the support plate 4 can be easily detached from the device, so that it requires little space for its transport and storage.
- D as A us Entrysbeispiel the device according to Figure 4 differs from that according to Vietnamese ⁇ Fig.l substantially da ⁇ by that the upper, the conveying members 7 having För ⁇ der worn 6 is easily replaceable.
- 4 rollers 40 are arranged sunk in the table top.
- the interchangeability of the conveyor 6 has the purpose of increasing the distance between the conveyor elements 7 when thicker articles, e.g. particularly large envelopes K are to be conveyed. In this way, the thickness of the conveying flow can be limited in order to ensure reliable functioning of the device.
- a frame 43 carrying the two guide rollers 41, 42 is inserted with its lower end into a hook-shaped recess 44 of a bearing block 45, and its upper end is pressed against the force of one Spring 46 pivoted, hook-shaped lever 47 held.
- a handle 48 At the other end of the lever 47 there is a handle 48 so that it only has to be depressed in order to be able to remove the entire conveyor device 6 from the device.
- a compression spring 49 enclosed in the bearing block 45 presses the conveying device 6 out of its holder.
- rollers 40 arranged in the table top 4 and rising slightly above their level fulfill the task of the flexible, flat articles K, which are somewhat thicker at their edge area, such as envelopes, in their central area in the removal direction or in the direction to press towards the support surface 5, 6 so that their upper edge there also comes into secure engagement with the rib-shaped conveying elements 7.
- they are fastened on a common shaft 50, which is driven by a belt 51 with the guide roller 29 of the conveyor belt 13.
- the drive and conveyor belts are also designed differently than in the exemplary embodiment according to FIG. 1. This embodiment is the result of the design of an easily detachable drive connection for the exchangeable conveyor device 6 according to FIG.
- This has a gear 53 connected to the lower guide roller 41, which meshes with a gear 54 which is provided on the upper guide roller of a drive belt 55.
- the reversal of the direction of rotation caused by the engagement between the gear wheels 53, 54 replaces the reversal of the direction of rotation by the gear pair 26, 27 of the exemplary embodiment according to FIG. 1, so that the drive belt 55 is driven directly by the drive roller 21 coupled to the motor 16 becomes.
