DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A device for binding a particularly compressible package 11, such as a stack of corrugated paper, is generally designated by the reference numeral 10 and is provided with a binding means holding portion (hereinafter referred to as "holding means") installed near the floor.
The holding part 12 comprises a binding means 14, which is wound on a drum 13, in particular a heat-weldable plastic band.

A lateral support 16 is arranged on each of the columns 15 and 15 'so as to be vertically movable in the direction of a bidirectional arrow 17. The lateral support 16 forms a pressing plate for compressing the package 11, or is a component of the pressing plate, and the unit 18 is supported on the upper side of the pressing plate. 14 and especially the binding means 14
This unit will be referred to as a fixing unit 18 in the following because it is used for fixing. The fixing unit 18 is provided with a binding means storage section (hereinafter referred to as a storage section) 19, and the storage section 19 moves integrally with the fixing unit 18 and is therefore driven in synchronization with the pressing plate 16. And it is movably guided.

The columns 15, 15 'and the lateral support 16 are provided with binding means guides 20-23 as linear passages or passage portions of known construction. Similarly, on the floor side, the insertion member 24 having a spear-shaped portion or a linear guide for binding means, which runs under the package 11 or the pallet on which the package 11 is placed, is directed toward the arrow 42 in FIG. It is known that a frame-shaped binding means guide passage portion is formed as a closed frame by feeding it to the position shown in FIG. 2 or FIG.

In order to wrap the binding means 14 around the package 11, the binding means 14 must first be supplied to the fixing unit 18. For that purpose, a binding means driving device (hereinafter referred to as a driving device) 25 is provided near the floor and immediately behind the drum 13 of the holding portion 12, and the driving device 25 includes the binding means feeding roller 26 (at least of them). One is mechanically driven and the other is forcibly connected thereto) and feeds the binding means 14 into a binding means guide (hereinafter referred to as a guide) 28 at the binding means supply designated 27. The guide 28 is
It is arranged side by side with the columnar guide 21 and parallel thereto. A bundling means direction changing member (hereinafter referred to as a direction changing member) 29 is arranged so as to be movable in the vertical direction along the guide 28, and each of the direction changing members 29 has a position where the direction changing member 29 exists. It serves to pass the binding means 14 to the binding means transition portion (hereinafter referred to as the transition portion) 30 arranged horizontally, and the transition portion 30 further guides the binding means 14 to the fixing unit 18. In this embodiment, this is done through the reservoir 19. As soon as the free end of the binding means 14 to be guided contacts the switch 31 in front of the fastening unit 18 in the feed direction, the initial position for the first binding of the packages 11 is obtained (FIG. 1).
See).

The articles 11 to be bound on a pallet or without a pallet are transferred to the binding area perpendicularly to the plane of the drawing, for example by a roller conveyor (not shown). Thereafter, the bundling means 14 is fed forward by a bundling means feed roller (hereinafter referred to as a feed roller) 32, and particularly, in the counterclockwise direction in FIG.
1, 24, 22 and their guides 20, 21, respectively
The diverting member 3 in the bundling means passage between 24 and 22
3 to 36, the front end of the binding means 14 reaches the fixing unit 18 again.

The pressing plate 16 and the fixing unit 18 are already or immediately after the bundling means 14 are circulated and fed.
And the storage 19 drops down on the upper side of the package 11, which is respectively compressed with a corresponding strength according to its characteristics and requirements.

After that, the driving of the feed roller 32 is reversed to tighten the binding means 14 around the compressed package 11, so that the feeding roller 32 guides the binding means 14 guided from the holding portion 12. The other end of the pulling-back and binding means 14 is clamped and fixed and held by the fixing unit 18. By pulling back the tying means 14, this tying means 14 is formed in a known manner and thus has a guide such as eg a flexible tongue 31 as shown in FIG. 6 or a flap which opens against spring action. It is pulled inward from the whole.

If the amount of binding means 14 becomes excessive, the binding means 14 are sent in the meantime back into the reservoir 19 where they form a stock, which stock:
Used at the beginning of the next unity. In order to be able to do this, a guide curve 43 (for example adjustable by means of a magnetic lifting device 41 (see FIG. 4)) is provided in the direction-changing part 40 in the storage part 19, which is shown at 40.

Feeding the tying means 14 from the floor to the anchoring unit 18 at any position of the apparatus, both upon initial insertion of the tying means 14 and after overcoming the drive obstacles associated with the tying means 14. You can After possibly removing the rest of the binding means remaining on the machine, the starting end of the new binding means is fed into the driving device 25, after which the device 10 automatically places the binding means 14 in the fastening unit 18, Alternatively, it is captured by the feed roller 32 inside thereof. Importantly, for this purpose, according to the invention, an additional guide 28 is provided which has a deflecting member 29, which guide 28 is synchronized with the transition 30. To move vertically,
The transition portion 30 itself is provided so as to move integrally with the pressing plate 16.

If the pressing plate 16 is slightly lifted, another package or the same package after being sent can be bound again in the same manner. When bundling the same package, it is known that two bundling planes E1 and E2 (see FIG. 4) are arranged in parallel, and in that case, the above-mentioned guide and direction changing member are also provided. Also doubled, but with only one sticking unit and optionally one reservoir.
They can therefore run transversely to the two binding planes E1 and E2, and thus in the direction of transport of the packages, or vice versa.

In that case, the transition portion 30 is formed so as to be displaceable as the unit moves. In this embodiment, the transition portion 30 can swing like a pendulum around the links indicated by reference numerals 37 and 38, in which case the link 37 is arranged in a fixed position in front of the direction changing member 29. The link 38 is linked by the fastening unit 18 or, in a specific embodiment, by the reservoir 19. As a result, not only does the height of the pressing plate 16 be unimportant when the binding means 14 has to be newly inserted, but also the respective lateral position of the fastening unit 18 with respect to the binding planes E1 and E2. It will be optional.

According to the invention, the guide 28 provided for driving the new binding means 14 at least semi-automatically is either one of the guides 21, 22 and the diverter 29 is one of the diverters 33, 36. It can be the same or exactly the same. In that case,
The guide 28 is simply displaced upwards with respect to the guides provided for the binding planes E1 and E2, as shown in FIG. This is because the binding means 14 must be fed above the pressing plate 16.
