Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to an apparatus for forming a compact pile of flat goods in a goods storage, said goods being automatically arranged for a plurality of sorting processes on the same sorting machine. Of the type received from the sorting compartment by a discharge device. Particularly in the case of the sequence sorting process, the contents of the sorting compartment are supplied to the new sorting section in a continuous order.

[0002]

2. Description of the Related Art According to EP 661 106, a sorting compartment is arranged above a delivery storage / pile bed. Delivery items are pushed out of the sorting compartment for individualization.

[0003] After the first sorting process has been carried out, the goods are simultaneously discharged from the sorting compartment into the goods storage. In this case, the delivery is prevented from tipping over at fixed intervals by the separating blade. Thus, deliveries from the various sorting compartments are not reassembled, but are maintained in adjacent fixed compartments. In this case, an uncompressed delivery pile results. If the compartments are non-uniformly filled, especially if the compartments are lightly filled, fast and accurate individualization cannot be guaranteed.

[0004] Further known configurations (Proceedings USPS Advan
ced Technology Conference Washington DC, 2. Dec.
1992, p. 1061-1074), a separate individualization / drawer is assigned to each sorting compartment. The compartments are emptied after the first sorting by the respective individualizing / withdrawal device in sequence and the deliveries are fed into a second sorting process. In this case, mechanical costs are disadvantageously increased.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for receiving goods from a sorting compartment, which can discharge goods separately, into a goods storage and combining them to form a compact goods pile. Sometimes.

[0006] This provides the prerequisite that pile deliveries are to be individualized quickly and accurately and re-sorted.

[0007]

According to the present invention, the above-mentioned object has been achieved by an arrangement according to the characterizing part of claim 1.

[0008]

According to the present invention, the delivery is continuously discharged from the sorting compartment, the delivery is received from the discharge sorting compartment, and the delivery of the last discharge sorting compartment is sequentially added to the pile formed so far. By forming the whole pile, a compact whole pile is formed, and this whole pile is
Individualization is assured and fast individualized by individualization devices, each of which draws the frontmost deliveries.

Advantageous configurations of the invention are set out in the further claims.

[0010] In claims 2 and 3, two different configurations of pile formation are obtained. According to the second aspect, the additional separating blade drives are arranged side by side, so that the separating blades cannot overtake each other during the transfer movement. Therefore, the central separating blade must be able to move closer to the outer additional separating blade and, after the central separating blade inwardly pivoting, the outer separating blade pivot upward and continue to move. In order to prevent damage to the delivery of the existing delivery pile during the inward turning of the central separating blade, according to an advantageous configuration of claim 8, the outer additional separating blade is double-walled. This allows the central separating blade to enter the intermediate space during the inward swiveling and to avoid damage to the delivery.

[0011] According to claim 3, the drive for the additional separating blades is arranged separately from each other, so that the additional separating blades can pass when receiving the goods.

This eliminates the pivoting movement compared to the first modified configuration.

[0013] With the configuration of claim 4, an advantageous transfer of the delivery pile is obtained.

[0014] In an advantageous embodiment of the invention, the inward swiveling of the outer additional separating blade opens the respective sorting compartment for the goods to be received, thereby reducing the cost. can get.

The structure of claim 6 requires cost,
There are many possibilities in receiving a delivery, for example in receiving a delivery from a plurality of filled sorting compartments at the same time.

[0016] Advantageously, the pile pressure of the deliveries can also be constantly measured in the deliveries storage during the assembling and / or individualizing of the deliveries and can be kept constant by moving the separating blades. Thereby, high driving safety is obtained.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As can be seen from FIG. 1, the delivery plane is inclined at approximately 45 degrees with respect to the vertical. Additional guidance to guide rejected shipments (eg, bar code unreadable, incorrect sorting plans, very small gaps, blockade rejections) or to guide deliveries after one sorting compartment 12 is filled. Below the series of sorting or sorting compartments 12 for sorting goods, comprising rejection compartments and overflow compartments 8,9, a first delivery storage 2 with underfloor bands and sidebands is provided. positioned.

The underfloor band and the sideband are at an angle of 90 degrees to each other, and store the delivery pile, and individualize the separation pile for sorting and individualization in another sorting process. 4 or after the last sorting operation in a container as an unloading point 10 for unloading.

Furthermore, the delivery storage 2 has separating blades, which are used for receiving the delivery from the sorting compartment, for forming a compact pile in the delivery storage 2 and for delivery. Used to support the transport of goods.

One closed separating blade is pivotable inward and outward (approach and departure pivoting) by hand relative to the storage bin 2 and is coupled to the movement of the underfloor band in an inward pivoting state. . The two separate separating blades are independent of the underfloor band,
Are mounted movably by means of a linear drive in parallel to and can be swiveled inwardly into the store 2 and thus again swivel outwardly.

The linear drives are arranged one on top of the other, so that no additional separating blades can pass each other. The movement progress is monitored via appropriate sensors.

The sorting is performed in the following two sorting processes.

1. All packages to be sorted are supplied to the lower package store 1 (automatic or manual).

2. Next, individualization from the delivery storage unit 1 and sorting into the sorting compartment 12 are started (first sorting process).

3. When all the deliveries are sorted, the deliveries are transferred from the sorting compartment 12 to the upper delivery storage 2.

4. Next, individualization from the upper delivery storage unit 2 and sorting into the sorting compartment 12 are started (second example).
Sorting process).

5. During the second sorting process, the lower delivery storage 1 is empty and the delivery can already be loaded for the next sorting (see step 1).

6. When the second sorting process is completed, the deliveries are transferred back to the upper delivery store 2.

[7] The first sorting process of the next sorting can now be started immediately (see step 2).

8. While the first sorting process of the second sorting is being performed, the machine is automatically or manually unloaded.
That is, the sorted delivery items in the upper delivery item storage unit are taken out.

[Outside 1]

According to FIGS. 2 to 9, starting from the last compartment on the discharge side, the delivery of goods from the sorting compartment takes place for each compartment individually. Two separating blades P1, which are pivotable and move independently in a straight line
A passage is formed by P2, which guides piles of packages of different widths from the sorting compartment 12 to the store 2.

The central separating blade P1 moves linearly via a toothed belt and a motor drive. The turning takes place via a co-moving transmission motor (Getriebemotor). The central separating blade P1 moves with the closed separating blade P3 and the existing compressed pile to the detected filling level and prevents the compressed pile located between the closing separating blade P3 and the separating blade P1 from tipping over. I do.

The pivotable outer separating blade P2 is driven like the separating blade P1. Since the drive units are arranged close to one another, two separately driven pivotable separating blades cannot be overtaken,
That is, the central separating blade P1 is always the central separating blade and can move only to the outer separating blade P2.

In order to prevent the pile of piles from being damaged when the central separating blade pivots inward near the outer separating blade, the outer separating blade must have the outer separating blade P2. It is configured as a double wall so that it can turn inward. That is, there is no contact with the delivery pile. Outer separation blade P2
Always moves to the sorting compartment wall of the stack at a constant pitch (sorting compartment width).

Outer separation blade P2 and sorting compartment 1
2, the bottom plate (flap) / baffle wall of the sorting compartment 12 is opened each time the separating blade P2 turns inward.

The time course is as follows.

Basic position: separation blades P1, P2, P3
Is in the basic position, ie all three separation blades P1, P2, P3 are located at the end of the device (container side).
The central separating blade P1 pivots upward and is located at the stacking point of the first sorting compartment 12 at the container-side end of the machine. The outer pivotable separation blade P2 in the pull-out direction is pivoted downward toward the delivery storage. The driver of the underfloor belt of the delivery store is connected to the closing separating blade P3.

Release of sorting compartment: central separating blade P
1. The underfloor belt and the closing separating blade P3 travel together with the already received delivery pile to the side wall of the respective sorting compartment, which is movable and thus secures the delivery pile. The outer separating blade P2 pivots downwardly at the stationary wall of the sorting compartment and thereby opens this sorting compartment. Therefore, the delivery slides toward the delivery storage (FIG. 2).

The central separating blade P1 pivots upward from the delivery pile (FIG. 3).

The center separating blade P1 moves toward the outer separating blade P2 (FIG. 4).

The center separation blade P1 pivots downward between the two walls of the outer separation blade P2 (fifth step).

The central separating blade P1 moves with the compressed pile of goods to the movable side wall of the next sorting compartment.

The outer separating blade P2 pivots downward (FIG. 8).

The above cycle is performed up to the last sorting compartment.

Preparation for individualizing the pile of goods after receipt from the last sorting compartment: The outer separating blade P2 occupies the position of the central separating blade P1.

The separation blade P1 at the center pivots upward.

The outer separating blade P2 travels beneath the central separating blade P1 to the individualizing device together with the underfloor belt, the delivery pile and the closed separating blade P3.

The outer separating blade P2 pivots upward and the individualizing device starts. In this case, the closing separation blade P3 and the underfloor belt move the delivery pile according to the individualization.

Preparation for the next sorting process: The outer separating blade P2 pivots downward.

The separation blade and the underfloor belt return to the basic position and move.

Discharge of the goods store: The outer separating blade P2 occupies the position of the central separating blade P1 and the central separating blade P1 pivots upward.

The compressed delivery pile moves back until the closed separating blade P3 is located in front of the container.

The operator pivots the closing separating blade P3 upward to prevent the delivery pile from tipping over by hand and to re-enter the delivery pile with the closing separating blade P3 shifted by the container pitch.

The delivery pile is now pushed into the container.

The separating blade and the underfloor belt advance the delivery pile to the container edge.

In FIGS. 10 to 16, the drive units for the pivotable separating blades are arranged in such a way that the separating blades can pass each other. In this case, one drive unit is arranged above the sorting compartment and the other drive unit is arranged below the sorting compartment.

In the basic position, the closed separating blade P3 and the first separating blade P1 are pivoted inwardly into the delivery storage by a drive unit arranged below the sorting compartment and before the last sorting compartment. To position. The separation blade P2 with the upper drive unit pivots upward and is located at the stationary sorting compartment wall.

Delivery: The separating blade P2 pivots downward and presses on the bottom plate / baffle wall. The deliveries in the sorting compartment slide towards the deliveries storage (tenth
Figure).

The separation blade P1 turns upward between the deliveries (FIG. 11).

The separation blade P1 moves to a position before the stationary wall of the next sorting compartment (FIG. 12).

The separation blade P2 is a closed separation blade P
3. With the underfloor belt and the delivery pile, proceed to the movable wall of the next sorting compartment. This closes the bottom plate / baffle wall of the sorting compartment, which has just received the delivery, again (FIG. 13).

As the separating blade P1 pivots downward and opens the bottom plate / baffle wall, the next sorting compartment delivery slides into the delivery storage (FIG. 14).

The separation blade P2 pivots upward between the deliveries and moves to the front of a stationary wall, such as the next sorting compartment.

The pile pressure is also excited at the time of receiving.
