DE2919624A1 - Stacking machine using intermediate layers - assembles item layers on table with two plates at different levels - Google Patents

Abstract

The machine forms a stack with stabilising intermediate layers, the items being formed into a layer and thrust onto a stabilising component and then transferred with it to a stacking table. The item layer is assembled on a collector table (4) comprising two support plates (4a, 4b) at a distance one above the other, and coupled at the rear to a ram (5). Alongside the table is a magazine for the stabilising components, its bottom plate being level with the lower support plate. The bottom plate can incorporate a slot, running in the lengthwise direction, and in which the dog of an ejector below, travelling towards the table, works.

Description

Device for forming a stack

The invention relates to a device for forming a stack with stabilizing intermediate layers, in which the means for providing a stabilizing element, means for forming a packaged goods layer, means for pushing the packaged goods layer on the stabilizing element as well as means for transferring the with a stabilizing pad provided packaged goods are provided on a stacking table.

It is known, stackable packaged goods, which in several rows is supplied, to be subdivided one after the other into individual groups, which are then used as packaged goods be pushed onto a cardboard pad. The cardboard pad is placed before the pushing process placed on a table. After the packaged goods have been pushed onto the The cardboard pad lying ready on the table is both fed to a conveyor (DE-OS 255970).

The disadvantage of this arrangement is that only one layer with a cardboard backing can be formed, because if a second layer is pushed onto the first, it would come there are good shifts within this. Furthermore, cardboard pads are in the Most cases do not plan, so that there is also interference when postponing the situation comes to the ready-lying folder, namely by the fact that the packaged goods against upstanding cardboard edges runs.

Another known device for introducing stabilizing elements between packaged goods layers is set up in such a way that above the feed conveyor for the packaged goods a magazine for cardboard blanks is arranged. By pushing off a row of packaged goods At the same time, a cardboard blank is pushed out of the magazine to form layers and arrives as Interlayer on the good row (DD-XP 66589). With this device it is not possible to place a cardboard sublave under the first Bring packaged goods, thereby applying the bulk packaging in shipping boxes remains limited.

The invention aims to provide a device in which the Packaged goods applied to stabilization documents without interference and using that the packaged goods layers provided with a stabilization underlay without interference can be stacked.

The object of the invention is to create a device in which the formation of the packaged goods layer is independent of the provision of a stabilizing base takes place at the same time as the latter process and disruptive influences from not flat Stabilization pads are avoided.

In accordance with the invention, the object is achieved in that the ittel for Forming the packaged goods layer as one of two in a certain position on top of each other arranged collecting table is formed on its back is connected to a working cylinder and that a magazine next to the collecting table is arranged, the bottom plate with the lower tray of the collecting table flees.

There is a longitudinal slot in the bottom of the magazine provided, in which an ejector tooth one below the floor panel, in its direction of movement the ejector directed towards the collecting table runs.

In front of the collecting table is an up and down retainer and at the level of the gap in the collecting table below the retaining element next to the Lying on the collecting level, there are two separating slides that can be moved in and out to the side.

The fact that the stabilizing pad is initially in the by the two storage sheets formed gap of the collecting table is inserted and on the upper storage plate the packaged goods layer is formed, and in that both together is driven over a stacking table and both when returning the collecting table the stabilization underlay as well as the packaged goods directly on the stacking table or a previously placed packaged goods layer is deposited, it comes up to this Point in time at no contact between the stabilization underlay and the packaged goods as well as to no relative movement, so that trouble-free function is ensured.

The invention is explained in more detail in the following exemplary embodiment.

The accompanying drawings show: FIG. 1: the top view of the Stacking device in a schematic design Fig. 2: Section A-A according to Fig. 1 Fig. 3: the section B-B according to Fig. 2 The stacking device consists of a Gralld frame 1 in which a conveyor belt 2 is mounted. Located at the end of the conveyor belt 2; themselves a stationary stop 3 with a limit switch (not shown). Next to the Conveyor belt 2, a collecting table 4 is arranged, which consists of two in. A certain There is a spacing of storage plates 4a and 4b arranged one above the other. The storage shelves 4a; 4b are at the rear leaving a small amount free to both Sides rigidly connected to each other. Via an extension of the lower shelf 4a, the collecting table 4 is connected to a working cylinder 5.

A second working cylinder 6 is arranged above the working cylinder 5, on its piston rod a separable 7 with two at an angle of 90 ° v to each other lying legs 7a and 7b is attached. The lower edge of the pusher 7 is located slightly above the upper run of the conveyor belt 2. In front of the front of the collecting table 4 is a retainer element that can be opened and closed over the entire width of this area 8 arranged. At the height of the gap in the collecting table 4, below the retaining element 8, are to the side, next to the collecting level, two controllable and controllable Separating slide 9. The retaining element 8 and the separating slide 9 are operated by working cylinders driven.

In front of the retaining element 8 is a stacking table 10 that can be raised and lowered arranged.

Next to the collecting table 4, opposite to the conveying direction of Conveyor belt 2, a magazine 11 is arranged, the bottom plate 12 in the longitudinal direction has a slot by having an ejector tooth 13 below the floor panel 12 arranged ejector 14 runs. The ejector is via a working cylinder driven.

The individual packaged goods G are transported via the conveyor belt 2 and accumulated in front of the stop 3. Simultaneously with the damming process is through the ejection tooth 13 of the ejector 14 the lowermost cardboard blank P from the magazine 11 ejected and pushed into the free space of the collecting table 4 and onto the lower storage plate 4a placed.

Is a predetermined number of individual packs G before the stop 3 accumulated, the working cylinder 6 is put into action and the accumulated Individual packs are placed as a row of packaged goods on the upper tray 4b of the storage table 4 postponed. The leg 7b of the pusher 7 holds the advancing individual packs G back during the push-off process. After the pusher 7 ran back is, another row is dammed up and pushed off, the second row the first one pushes ahead after a predetermined number of rows on the top one Storage area 3b is pushed on, the working cylinder 5 is put into action, the collecting table 4 with the packaged goods layer located on the storage plate 4b and the cardboard blank P located on the storage plate 4a over the stacking table 10 driven. In the front position of the collecting table 4, the retaining element 8 down- and the slide valve 9 controlled so that the retaining member 8 behind the last row of the packaged goods layer engages and the separating slide behind the cardboard blank P arrive. After this process, the direction of movement of the working cylinder 5 reversed and the collecting tray 4 withdrawn. The packaged goods as well as the cardboard blank as they are retained by the appropriate means, thus simultaneously of the storage plates 4a; 4b stripped and placed on the stacking table 10 or one itself Packaged goods already located on it are deposited. After the return of the collecting table 4 a new layer formation cycle begins. The movement sequences can accomplished with known pneumatic or electromechanical sequential controls will.
