EP3192757B1 - Stacker device for flat goods - Google Patents

Description

The invention relates to a storage device for flat goods according to the preamble of claim 1. Such storage devices are used, for example, in good processing systems or as the last station of a postal road. A post street of a franking system consists of individual mail processing stations lined up and the flat goods are mail pieces. At the beginning of Poststrasse, a docking station can be set up, which is used to create individual or stacked items of mail, which are transported downstream from the poststream through further stations to the end of the Poststrasse to the storage device. A stack of mail pieces of different formats (mixed mail), which has been placed at the loading station, is separated in the post street by means of a separating device of a feed station immediately following in the transport direction, since further subsequent mail processing stations require individually fed mail pieces. The storage device for a flat good is intended for use in connection with previously arranged good processing devices, for example mail processing stations in connection with franking machines, addressing machines and other mail processing stations.

Mixed mail should also be understood to mean format-like mail pieces that differ in height and width within limits of up to 10%, for example letters in formats B6 (12.5 x 17.6 cm) and C6 (11.4 x 16.2 cm).

When a stack is subsequently spoken of, it means a stack of letters, a stack of postcards, a stack of mailpieces or other stacked goods or stacked goods which can be separated and fed in lying on the side.

In the field of franking machines, solutions are known which transport a mail piece downstream in the transport direction and print a franking imprint during the transport. A device for transferring mail to a storage device is already from the European patent EP 985 619 B1 known. However, the amount of mail items received by the storage device is marginal. The filing device is unsuitable to orderly accommodate a larger amount of mail items.

A storage device for larger quantities of stacked mail items is to be understood below under the term stack box.

Such a box-shaped box of small dimensions is for example from the Japanese patent application JP 2000063026 A previously known. The bottom of the box is not inclined. A front side wall can be opened like a door to remove the stack of items of mail, for example postcards. The problem does not arise for postcards of the same format as for postcards of different formats, namely that a large stack threatens to tip over.

In contrast, this shows Patent US 6,648,284 B2 an adjustment insert block within a goods storage trough which has a bottom surface and a plurality of upstanding side walls which are connected to the bottom surface of the goods storage trough. The adjustment insert block has a double inclined surface which causes the stack of mail items to be aligned at a corner of the goods storage trough. Thus, a stack of mail items of different formats is also stored in an orderly manner in the goods storage trough.

Another Japanese patent application JP 2002234659 A has two wedge-shaped bevels on the bottom of a box, the surface of which is inclined backwards to a guide wall for the purpose of receiving paper sheets. A stop wall forms a downstream end of the box. At the end of the box, a guide wall projects into the area of trajectories of the paper sheets, in contrast to the beginning of the box. A paper sheet with a maximum trajectory therefore strikes the guide wall first and then falls on the slants at the bottom of the box.

From the US 7,568,694 B2 a pressure medium collector is known which comprises a guide surface with an inlet edge and an outlet edge, the guide surface being inclined downwards from the inlet edge to the outlet edge, so that when a printer releases a pressure medium which is gravitationally directed over the outlet edge onto the guide surface falls and is moved with a leading edge of the printed medium within a range of trajectories, each trajectory having a downward and lateral component. A stop on the back of the accumulator area can cause lateral movement block the print media so that such printed media is stored on a support surface against the stop to form a stack. The aforementioned range of trajectories includes a maximum trajectory in which the leading edge of the print medium is able to first contact the stop and only then come into contact with a print medium that is already on the support surface. The support surface is only inclined downwards in the transport direction. The print medium collector is well suited for sheet-shaped print medium of fixed length, but is unsuitable as a collector of mail items with a different format (mixed mail).

From the EP 1443008 B1 A device for receiving mail items is known in order to receive the mail items ejected via an exit slot of a folding and inserting machine. The ejected mail items accumulate on a carrier plate, which will hit a stop wall. Two side walls and one wall are intended to realign these mail items as soon as they have fallen onto the support plate, the wall having coupling means in order to enable the receiving device to be plugged onto the front feet of a folding and inserting machine. However, the receiving device is not completely satisfactory because, in the case of a rapid ejection of mail items with an identical format, an uncontrolled rebound does not form a uniform stack. From the US20110074084 A1 a printer with a tray is known in which a plurality of separating sections for file papers are arranged. The shelf is arranged at the front on a rear plate inclined to the rear of a holder, the separating sections of the shelf forming ascending steps. The filing has a filing opening for a drive element that places filing papers sorted in compartments of the filing.

In the patent US 8590888 B2 proposed a storage device for storing mail items that are ejected from a franking machine out of the exit slot. The storage device comprises a receiving plate for receiving mail pieces, a longitudinal alignment wall which extends over a longitudinal edge of the receiving plate and perpendicular to the outlet slot and on which the mail pieces hit before they accumulate on the receiving plate, and a vertical rear wall which extends along a side edge the receiving plate extends, and which the mail items hit before they strike the longitudinal alignment wall, the vertical rear wall forming an angle β to a perpendicular to the longitudinal alignment wall and the receiving plate being inclined at an angle ϕ relative to the horizontal and in the direction of the longitudinal alignment wall , so that the angle α between the mounting plate and the longitudinal alignment wall forms an acute angle of less than 90 °. The longitudinal alignment wall is opposite the vertical direction and inclined downward to the mounting plate at an angle Δ. The manufacture of the bearing device is complicated because the longitudinal alignment wall is bent over the longitudinal edge of the mounting plate with a rounding and all the aforementioned angles α, β, Δ and ϕ are acute angles. With a medium-speed ejection for mail items with a different format (mixed mail), it is not guaranteed that a stack is formed in an orderly manner and cannot tip over. The stacks tend to tip over from a certain height. The mounting plate has a raised rim on the front, but this is only effective for a very small stack height. The device is unsuitable for picking up and orderly collecting mixed mail. Due to the curves on the receiving plate, mail items of different sizes cannot be aligned on one edge, especially if the bottom mail item of the stack has a very small format. The deposited mail pieces can not always be easily removed. The boundary edge drawn up at the front interferes with the removal of the stack from the storage device. A predetermined number of pieces of mail can be franked and ejected via a setting on the franking machine. In the case of mixed mail, however, the removed stacks can have a different stack height, which depends on the thickness of the mail pieces. Another disadvantage is that the mail pieces cannot be stacked to a desired stack height, at which the stack can be easily gripped by hand.

It is an object to provide a storage device for a flat good, which does not have the disadvantages mentioned above.

A storage device arranged at the end of the post street, which is provided, for example, for a franking machine standing on a table top, is intended to accommodate a larger amount of flat goods (mail pieces) with a different thickness and a different format (mixed mail).

The object is achieved with the features of the storage device according to claim 1.

A storage device comprises a receiving plate for receiving flat goods, a longitudinal alignment wall which is graduated in at least two stages on a rear side of the storage device and a stop wall which is arranged at the downstream end of the receiving plate.

Several flat goods lying on their side, such as letters and other mail pieces, can be stacked in a stack. A front side of a receiving plate of the storage device extends downstream and lies in a reference plane which forms the front side with a perpendicular which is parallel to the front side of a second vertical which is perpendicular to the receiving plate. As soon as stack parts protrude through the reference plane, mixed mail runs the risk that the stack will become unstable if the stack height continues to increase. It was found empirically that the stack leans against the longitudinal alignment wall, but cannot tip over up to a certain stack height, and that the position and design of the longitudinal alignment wall play a decisive role in an orderly storage. The graded longitudinal alignment wall limits the stack height of partial stacks, which are therefore stable. The stacking of a large number of partial stacks is made possible by an inclination of the receiving plate, the partial stacks leaning against the longitudinal alignment wall due to the inclination. A further inclination of the receiving plate enables the stacks to be placed in an orderly manner, which are aligned at the corner where the longitudinal alignment wall and the stop wall meet.

Perspective view of a good processing device with a stacking box for stacking flat goods.

The Fig. 1a shows a schematic representation of a stacking box from the right, according to the prior art on which differently flat goods are stacked. The stack has grown beyond a reference level on the front side and threatens to tip over or the uppermost mail items 3 threaten to slip off the stack.

The Fig. 1b shows a schematic representation of a stack box from the right, with gradation of the longitudinal alignment wall. The angle α between the receiving plate and the longitudinal alignment wall 22 preferably forms a right angle. On the inside of the angle there is a straight line at which the receiving plate and the longitudinal alignment wall abut one another or at which the longitudinal alignment wall is angled from the receiving plate. The aforementioned line on the longitudinal alignment wall 22 is referred to below as the longitudinal edge. The longitudinal alignment wall has vertical steps, an edge 20b of the receiving plate running parallel to the longitudinal edge being provided on a front side F of the storage device, which extends at a distance B from the longitudinal edge, a step-wise decrease in each step STi of the stepped longitudinal alignment wall Distance Bi <B of the step to the reference plane on the front results. The distance B is the effective width of the receiving surface of the receiving plate for a stack. The mounting plate is inclined by the angle ϕ to the horizontal H and the longitudinal alignment wall is inclined by the angle ϕ to a first vertical S1. A sub-stack Pi is represented for each stage STi - with Pi an element from P1, P2, P3, P4 - is shown, the sub-stacks representing the gradation. For i = 1, there is a first step ST1 and a partial stack P1, which bears against a first partial section 22b of the longitudinal alignment wall 22, which extends in height from the longitudinal edge to the first step ST1. This is followed by a second section 22c of the longitudinal alignment wall 22, which extends to the second step ST2. From a third stage ST3, a third section 22d follows the longitudinal alignment wall 22. At the upper end of the longitudinal alignment wall For example, a plastic part 22g can be attached that forms a fourth step ST4 and upper section of the longitudinal alignment wall 22.

$$\mathrm{mit}\mathrm{T}=\mathrm{h}·\tan \mathrm{\phi },$$

The Fig. 2a shows a schematic representation of a stack box according to the invention from the right, with gradation of the longitudinal alignment wall 22 according to a first embodiment. The first step ST1 is spaced from the longitudinal edge with the step height h. It is closer to the longitudinal edge than the second step (not shown), which is spaced at 2 hours. The same step height h and step depth T are preferably provided for each step. The distance B is reduced by one step depth T with each step i. The following applies: $$\mathrm{Bi}=\mathrm{B}-\mathrm{T}$$

$$\mathrm{With}\mathrm{T}=\mathrm{H}·\tan \mathrm{\phi },$$

The step depth T results from an inclination of the receiving plate 20 in the direction of the longitudinal edge of the longitudinal alignment wall 22, with an inclination of the receiving plate at an angle ϕ to a horizontal H. The maximum stack height c of the first partial stack up to the first step is: $$\mathrm{c}=\mathrm{H}.$$

The number of stages i (with i = 1, 2, 3, ..., n, ..., u) is at least i = 2, preferably n and a maximum of i = u. The smallest letter format in Germany is C6 (11.4 x 16.2 cm). The step depth is therefore preferably in the range T = 1 to 7.5 cm and, for example, T = 1.44 cm. The step height is preferably in the range h = 2T to 5T and, for example, h = 4T = 6 cm. Because tanϕ = T / h = 1.44 / 6 = 0.24, there is an angle ϕ of 15 °. For example, at T = 2.3 cm and h = 6 cm there is an angle ϕ of 23.3 °.

The longitudinal alignment wall is designed to be stepped vertically, so that stacked flat goods lying on the side again find an easily accessible stop surface on the underside of the step from a certain stack height. A vertical (dashed) on the stop surface on the underside of the step is preferably parallel to a second vertical S2 (dashed), which is perpendicular to the mounting plate. The uppermost of the flat goods in the first stack has a slight positive fit with the underside of the step, which gives the first stack an additional hold. The step depth T and / or step height h can be uniform for each step or - in a manner not shown - decrease with the number of steps.

The Fig. 2b shows a schematic representation of a stack box according to the invention from the right, with gradation of the longitudinal alignment wall with an alternative design. A perpendicular on the stop surface is parallel to a first vertical S1, which is perpendicular to the horizontal H. This improves the interlocking of the uppermost flat stacked goods of the partial stack with the stop surface when a further partial stack rests. The stack height c 'up to the first step remains the same as the stack height c, only the step height h is increased by Δh = T • tanϕ to h', which increases the material consumption for the longitudinal alignment wall. An acute angle is formed between the wall section which determines the step depth T 'and the wall section which increases the step height h' by Δh.

This detail comes from the Fig. 2c forth. The step depth T 'is also increased compared to T, but only marginally by ΔT' (not shown). The additional material consumption for this is negligible.

In a further embodiment variant (not shown), the wall sections form an obtuse angle for the step depth and the step height. This has the advantage that the arrangement of the uppermost flat stacked goods in the partial stack is improved.

In each step, the flat goods lying on the side with their one edge can be aligned again with the longitudinal alignment wall. These steps ensure that the flat goods of each stack are more stable and that each stack has a stack height that is uniformly in a predetermined range. Tilting of a first stack forward is also prevented, even though a further stack of the next stage lies on the surface of the first stack, since the uppermost of the flat goods of the first stack has a slight positive fit with the underside of the step, whereby the first Stack gets an additional hold.

Grading gives the advantage of a better removal of partial stacks, because the gradation is reflected in the partial stacks of the entire stack and the majority of the partial stacks thus have approximately the same stack height. It is not necessary to remove the entire stack at once, but the removal can be done in partial stacks from top to bottom.

Alternatively, the step height and step depth can be made variable without the basic function of the step being impaired. The longitudinal alignment wall is made, for example, of metal, preferably sheet steel.

An additional advantage arises from the possibility of further reducing the wall thickness of the longitudinal alignment wall, since the gradation improves the stability of the longitudinal alignment wall. This also reduces the weight of the stack box, which is customer-friendly and inexpensive.

The Fig. 2d shows a schematic representation of a stack box from the right and with an obtuse angle between the receiving plate 20 "and the longitudinal alignment wall 22" and with gradation of the longitudinal alignment wall. As an alternative to the right angle, an obtuse angle α can be implemented in order to increase the depth of the step. Consequently, at an obtuse angle α, the slight positive engagement with the underside of the step is also improved in accordance with the increase in the depth of the step.

The distance between the longitudinal alignment wall and the reference plane increases at an obtuse angle α = 90 ° + γ up to the first step by E ". The distance Bi" of the step from the reference plane compared to the distance B "the one edge 20b" of the mounting plate 20 on a front side F of the storage device to the longitudinal edge decreases for smaller angles γ <ϕ with an increase in the depth of the step to: $$\mathrm{T}‶>\mathrm{T}=\mathrm{H}·\sin \mathrm{\gamma }$$

The distance B to the longitudinal edge is reduced with each step by a part D "of the step depth T" = D "+ E". The following applies: $$\mathrm{Bi}‶=\mathrm{B}‶-\mathrm{D}‶$$
