Description

In the drawing: Fig. 1 shows a side view of the preferred Embodiment together with the packaged goods, with insignificant parts of the strapping machine are omitted, F i g. 2 shows the same side view as in FIG. 1, where However the packaged goods are now rotated by 90 ° and the press beam is in the upper position located, F i g. 3 shows a plan view of the embodiment according to FIG. 1, 4 shows a plan view of the embodiment according to FIGS. 2 and 5 Top view of the embodiment after the second strapping.

With 10 and 12 are two vertical guides of the strapping machine for guiding an upwardly and downwardly movable press beam 14 designated. The press beam 14 has on its underside a plate body 16 around a vertical Axis 18 is pivotally attached to the press beam 14 on its underside. The plate body 16 also has a gripping device in the form of two extendable and retractable fingers 20, the hydraulic or pneumatic actuating cylinder not shown in the Plate body are driven.

The packaged goods 22, for example a stack of newspapers, is for example fed with the help of two belts 24 of the strapping machine in which he is under the Press bar comes to rest The press bar 14 is then out of its upper position lowered and presses the stack of newspapers 22 together. Is the pile of newspapers compressed so the strapping is done with a tape preferably made of plastic 26, the fingers 20 being in the extended position during this strapping process Position. The extended fingers 20 are thereby removed from the plastic band 26, as shown in FIGS. 1 and 3, taken. From Fig. 3 it can also be seen that that the press beam 14 and the plate body 16 do not interfere with the strapping process. The edges of the press beam and the plate body opposite the plastic band run parallel to and at a short distance from the plastic tape.

After this first strapping, the press beam is together with the gripped newspaper stack 22 moved into the upper position, whereupon the plate body 16 is pivoted 90 ° about the axis 18, as shown in FIG. then the fingers 20 are moved back, so that the newspaper stack 22 on the belts 24 falls down. This is in FIG. 2 illustrates.

Before the second strapping, perpendicular to the first strapping, must the plate body 16 can be pivoted back to its original position in which its Edge again runs parallel to the edge of the press beam. This is in FIG. 5 illustrates. The second strapping can then be carried out, preferably with the press beam also for compressing the stack of newspapers along the second strapping is shut down. However, the fingers remain retracted during the second strapping, so that after the second strapping of the newspaper stack over the straps 24 immediately the strapping machine can be conveyed out.

That the fingers were already extended during the first strapping, has the advantage that the press bar can be pressed together with the fingers extended of the newspaper stack can be lowered so that in the compressed state of the packaged goods Injuries to the packaged goods from extending fingers as well as from Moving the packaged goods can be avoided. It also affects this fact too on the packing time favorably.

Claims (3)

Claims: 1. Strapping machine for strapping packaged goods with a band, for compressing the packaged goods during the strapping process one acting from above on the packaged goods over the entire width or length of the packaged goods extending upward - and downwardly movable pressing member provided is along which the tape is laterally strapped at a small distance runs, characterized in that the pressing member (14) one around a vertical axis has pivoting part (116) which can be pivoted by 900, on which in a manner known per se a gripping device which can be extended and retracted into the strapping path of the band (26) (20) is arranged. 2. Strapping machine according to claim 1, characterized in that the pressing member extends over the entire width of the packaged item (22) The press beam (14) and the pivoting part act directly on the packaged goods (22), plate body, known per se, arranged on the underside of the press beam (14) (16) is 3. Strapping machine according to claim 1 or 2, characterized in that the gripping device at least two spaced apart, retractable and extendable The invention relates to a strapping machine for strapping of packaged goods with a tape, whereby to compress the packaged goods during the Strapping process a from above on the packaged goods acting over the entire Upwardly and downwardly movable pressing member extending width or length of the packaged goods is provided, along which the tape laterally when strapping in a small Distance runs. A strapping machine of the type in question is, for example from DE-OS 29 47 718 known. According to this publication, however, the pressing member is a plate-shaped one Body below which the strap runs during strapping. Is it necessary that packaged goods with two mutually perpendicular To provide strapping, this is usually done according to the state of the art achieved that after strapping the packaged goods on a second arranged behind it Machine, after the packaged goods have been turned 90 ", with a second strapping is provided. This requires a high level of technical effort. The second could Strapping itself is carried out in the first strapping machine if the packaged goods are in the first strapping machine is rotated 90 ", but require this eligible facilities a large space or can be retrofitted install only with great difficulty. For example, DE-AS 12 77 108 describes a tying device known for the cross-wise tying of a packaged goods, in which the packaged goods on a Turntable comes to rest and is pressed down by a rotatably mounted pressing member is, because when rotating the packaged goods on the turntable in the depressed State can rotate freely. The pressing member does not extend over the entire width or length of the packaged goods, but only acts in the area of the axis of rotation on the packaged goods. According to GB-PS 20 87 832 is a device for cross binding of paper stacks known, in which the paper stack in the strapping station with With the help of a slider, the tape is wrapped around the stack of paper being held by four fingers at a distance from the stack of paper, then the stack of paper is pushed up against a holding plate, the fingers withdrawn and the tape is pulled into engagement with the stack of paper, then the stack of paper moved out of the strapping station with the help of the slider and rotated 90 " whereupon he goes back to the strapping station for a first strapping order 90 "twisted strapping is retracted. From US-PS 37 83 773 a strapping machine is known in the packaged goods to a bottom-side rotatable pressure stamp relative to the strapping device can be precisely aligned. The invention is now based on the object of a strapping machine of the type mentioned in such a way that the packaged goods in the strapping machine for a second strapping that runs perpendicular to the first strapping can without extensive modifications to the known strapping machines so that it is suitable for retrofitting. This task is performed with the strapping machine that was assumed to be known at the beginning according to the invention achieved in that the pressing member is one around a vertical axis 90 "has pivotable pivoting part, on which in a known manner a arranged in the strapping path of the tape retractable and extendable gripping device is. The strapping machine according to the invention works as follows: The the Packaged goods fed to the strapping machine are compressed by lowering the pressing member. The compressed packaged goods are then strapped with the tape, with the pivoting part and the gripping means are in such a position that when strapping the gripping device is encompassed by the tape from above. Then the press member lifted together with the packaged goods. The swivel part is swiveled through 90 "together with the packaged goods, whereupon the gripping device is moved back so that the packaged goods fall down. then the second strapping running perpendicular to the first is carried out, wherein after the pivoting part has been pivoted back with the gripping device retracted the packaged goods also along the second strapping perpendicular to the first strapping Strapping can optionally be compressed by the pressing member. The invention is characterized by its particular simplicity. The gripping device advantageously comprises at least two of each other spaced fingers that can be retracted and extended. The description of a preferred one follows with reference to the accompanying drawing Embodiment.
