Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package binding device for binding packages by a tape-like binding material which is introduced from a tape storage section into a tape supply channel and is passed through the channel and supplied to a tape fastening unit. Hereinafter, this device is simply referred to as "this type of binding device".

[0002]

BACKGROUND OF THE INVENTION Most tape tying devices have an essentially rectangular, partially open frame that includes a tape guide channel and is secured to a machine mount, as described, for example, in German Patent No. 362700. The frame end in the region below or inside the package mounting surface is connected to the tape guide on the machine rack side including the tape fastening unit, and complements the guide to form a ring surrounding the package.
Therefore, the packages to be bound must be transported across the binding surface defined by the frame.

In special cases, it may be desirable or necessary, in particular, to feed very long packages (eg rods, plates, beams, etc.) to the binding station in a direction perpendicular to its longitudinal direction. For this type of application, "a bundling device of this kind" is used which has a multi-piece frame that can be assembled and disassembled rather than a fixed frame.

In known devices of this kind, the frame is
It consists of two halved frame halves with shapes ranging from approximately L-shaped to C-shaped. In order to start a frame of this kind from the binding position in the binding surface of the device and disassemble and send it to the retracted position outside the device, the frame half is first moved around an axis extending perpendicular to the package mounting surface. The packages are swiveled in the opposite directions by about 90 °, and then descended inwardly or inwardly of the package mounting surface. If the package is placed on the package-placing surface for bundling, both frame halves are correspondingly placed in the opposite order of motion, i.e., first on the package-placing surface by translational movement from the retracted position. And then pivoted about the relevant longitudinal axis of the translational motion to form the frame and to a final position for bundling to form an actuatable frame.

[0005]

The drive means (for example, the guide columns, the swinging / lifting device) necessary for this purpose is complicated, and in particular, like the frame, it does not take up a large space, but the frame is assembled. In addition, a considerable time is required for the disassembly, and neither the loading or unloading of the packages nor the binding work can be performed within this time. This is therefore a particularly serious deficiency in view of the larger work cycle of modern binding devices of the type mentioned first, ie with a fixed frame.

Therefore, the object of the present invention is to prevent the operation of assembling and disassembling the frame from interfering with the work of binding and carrying in or out of the packages, that is to say that the device can be operated in a faster work cycle. Seed binding device ".

[0007]

The binding device of the present invention binds a package by a tape-shaped binding material which is introduced from a tape storage section into a tape supply channel and is passed through the channel and supplied to a tape fastening unit. In the device, the tape guide channel is provided in a frame composed of two frame halves, and both frame halves rise inward from the retracted position to the package mounting surface and close in the binding surface. In the form of forming a frame, bundling it, reopening it, and then descending to the retracted position, the frame halves (23, 24)
Is closed with its ascending movement, descends with its opening movement, and is displaced laterally with respect to the binding surface (25) so as to assume a retracted position along with the device member (16) in the binding surface. Characterize.

In this case, it is important that both frame halves are not swung with a large angular stroke before descending or after ascending. Instead, an opening movement with a descending movement of both frame halves and an ascending movement with a closing movement of both frame halves respectively take place with a lateral displacement of the preceding or following or simultaneous short stroke.

Conventionally, two movement processes with extremely long strokes are required for assembly and disassembly, but according to the present invention, the movements required are extremely short lateral movements. This movement can be performed rapidly due to the short stroke and / or the small mass acceleration force required. Correspondingly, the drive can be designed simpler and lighter.
Another advantage resides in the short and compact construction of the entire device.
This is because no special receiving space is required on the side of the machine cradle in order to pivot or fold the half of the frame laterally.

By arranging the frame halves so as to be pivotable about an axis which extends essentially at right angles to the binding plane, the longitudinal direction of said axis determining the direction of lateral displacement of the frame halves. A structurally very simple solution is obtained. Thus, the frame halves of the device according to the invention can be opened and closed in a plane coinciding with the binding surface or parallel to the binding surface, and the above operations can be completely superposed in time. The frame halves can be opened and closed by swiveling in the plane, during which the frame halves are lowered or raised and are free to move laterally along the package on the package loading surface. On the other hand, conventionally, it is impossible to significantly superimpose a predetermined motion component for lowering the frame half portion during the open swivel or moving it on the package mounting surface during the closing. Because half the frame, on the other hand,
On the other hand, due to the structure, on the other hand, if the frame half is not completely swiveled to the position corresponding to the corresponding opening on the package loading surface, it moves at a right angle to the package loading surface. Because you can't.

In accordance with another feature of the invention, further, each frame half is provided with an essentially partial elliptical shape in the form of a parabolic portion, with the parabolic vertices lying in the dividing plane of the frame half, as required. If so, it is advantageous to engage the pivot arm at the end of the frame half away from the parabolic apex. In the case of a frame half configured and pivoted in this way, the space required for its movement process is particularly small.

The above and other advantages will be apparent from the following description of the invention with reference to other dependent claims and the illustrated embodiments.

[0013]

EXAMPLE A machine frame 11 of a binding device (particularly, a tape binding device using a weldable synthetic resin tape) indicated by reference numeral 10 is provided with a drum 12 for storing a binding material. The tying material 13 is fed via a frictionally driven or forcibly engaged storage part filling roll 15 to a tying material storage part 14 which receives the quantity of tying material necessary for at least one tying operation. The binding material 13 is a pair of pulling rolls 1 from the storage section.
6, through the binding material tensioner 17 and the introduction roll pair 18,
It is supplied to the tape fastening unit 19 inside the apparatus below the package mounting surface 20.

A frame, generally indicated at 22, is required to bind the two sizes of packages 21 on the package mounting surface 20. In this case, by the tape guide provided on the frame, the binding material 13 guided from the binding material storage drum 12 through the fastening unit 19 is passed through the frame 22, and is installed around the package, and the binding material front end is again set. Introduced into the fastening unit 19, both ends of the binding material overlapping in the unit are joined together by the unit, in particular,
Weld. This operation is performed after first releasing the binding material 13 guided around the package 21 in the frame 22 from the frame 22 and pulling back the binding material 13 by the roll 16 to tension it. The basic structure described above is standard for tape tying devices.

Furthermore, a frame 22 consisting of two partial frames or frame halves 23, 24 is known. The purpose of such division of the frame 22 is to provide the package loading surface 20.
The frame 22 required for bundling is assembled outside or above, and after the bundling operation, the frame halves 23, 24 are lowered below or behind the package placement surface 20. As shown, the frame halves 23, 24 are opened and closed by a pivoting movement (which will be described in more detail below) in the binding plane shown at 25 in FIG. 2 or in a plane parallel to said binding plane, In the meantime, that is, at the same time, simultaneously, it is lowered to the retracted position shown by the broken line in FIG. 1 or raised above the package mounting surface 20 to form the frame 22 in the closed state (shown by the solid line). .

As is apparent from FIGS. 1 and 2, the frame halves 23 and 24 each have a partially elliptical shape, and are curved (concave) to face each other like the parabolic portion. In this case, the parabolic apex 26 is at the zenith of the frame and coincides with the boundary surface 27 of the frame halves 23, 24. Unlike the circular arc shape or the rectangular shape, based on the above-mentioned shapes of the frame halves 23 and 24, both frame halves do not require a large space due to the swiveling motion about the axis perpendicular to the paper surface of FIGS. Can be moved from the actuated position of FIG. 3 to the retracted position of FIG. 5, in which case the frame halves do not overlap at 28 (FIG. 5).

Each frame half 23, 24 is fixed to a swivel arm 29, 30 at an end inside the apparatus, respectively. The revolving arm 29 is movably arranged around the revolving shaft 31, and the revolving arm 30 is movably arranged around the revolving shaft 32. Both swivel shafts 31 and 32 are located below the package mounting surface 20 and outside the other half of the frame that faces the half of the frame. That is, a very large turning radius is obtained for both frame halves 23, 24. This large radius and each frame half 2
Due to the partial parabolic shape of 3,24, the two frame halves can be opened or lowered without being displaced laterally (to the left or to the right in FIGS. 3 and 5), or It can be raised or closed.

As shown in FIG. 5, the frame halves 23 and 24 are driven by an electric motor 33 (schematically shown) in which a motor shaft 34 is fixed to a crank arm 35 having a free end which engages a push rod 37 at 36. Done by. Push rod 3
The other end of 7 is connected at 38 to a swivel mechanism 39. The swivel lever 41 of the swivel mechanism is pivotally supported by 40, and the push rod 4 that swivels the swivel arms 29 and 30 around the swivel shafts 31 and 32 via the coupling levers 44 and 45.
It is pivotally attached to 2,43. The tension spring 50 acts on the turning lever 41 of the turning mechanism 39 at one end and is fixed to the device at the other end. The purpose of this tension spring is to load both frame halves 23, 24 for closure in the end position (FIG. 3) forming frame 22. Spring 5
0 further pulls during opening of the frame halves 23, 24 (see in particular FIG. 5) and thus also serves as an accumulator, raising the frame halves 23, 24 from the retracted position of FIG. 5 to the operating position of FIG. To support the driving force needed to close.

By driving both frame halves by the crank arm 35 via the electric motor 33 as described above, the frame half 23 is responded to the turning of the crank arm 35, that is, the transition of the sine curve. , 24 are accelerated or decelerated, so that both frame halves are first raised at a low speed from the retracted position and then very rapidly partly closed, while the frame halves 23, 24 just before frame formation. The movement in the final stage is again slow and
That is, it is performed gently.

Based on the above-mentioned turning mechanism, the opening / closing movement of both frame halves accompanied by the descending / ascending movement is basically performed by the binding surface 2.
Complete within 5 However, especially the frame half 23
In the above motion path of the device member (for example, the roll system 1
6. Since the bundling material 13) is provided, at least the frame half portion 23 needs a sliding motion at a right angle to the bundling surface so that it can be juxtaposed with the unit on the apparatus side in the retracted position. Therefore, according to the present invention, the sliding bearing 5
The swivel shafts 31 and 32 are configured as push rods that are movably supported on the shaft 1. In this case, the cross beam 46 connecting the two pivots
The crank arm 47 of the second electric motor 48 acts on (FIG. 4). Both frame halves 23, 24, in addition to the vertical and lateral movements, are in the lateral direction, and more specifically (as shown in FIG. 6) actually a section 49 of approximately 50 mm.
Only displaced. This lateral movement causes the frames 23, 24 to
It is completed at the end of the ascending / closing motion of the above, and conversely, at the beginning of the motion in the case of opening / descent. In this case, the temporal superposition (synchronization) serves for speeding up and is preferred, i.e. the lowering movement is started after the execution of 1/2 stroke of the section 49 and correspondingly the frame half 23, The second half of the return stroke to the binding position in the final raising and closing phase of 24 is performed.

As previously mentioned, the in-apparatus ends of the frame halves 23, 24 do not overlap at 28 (FIG. 5). However, since the swivel arms 29, 30 act on the corresponding frame halves at the intersection, the overlapping of the two frame halves is not prevented. Each swivel arm 2
The mounting legs 29a, 30 are attached to the mounting legs 29a, 30 so as not to collide.
The lengths of a are formed in different L shapes, and therefore,
Revolving arm portions 29, 30 extending parallel to the binding surface 25
Are offset from each other.

The device is furthermore particularly suitable for so-called ring bundling. This is a bundling of ring-shaped packages (e.g. cable coils, etc.), in which case the bundling material must be wound through the central ring opening. A package of this kind is placed flat on the package mounting surface 20 and the position of the movement path through which one of the two frame halves 23 or 24 passes through the center of the ring opening (see FIG. 1). Place it on the upper left side of the reference numeral 19 or on the right side of the reference numeral 13).
When the frame half is raised, it passes through the ring opening and thus the rings can be easily bound together. When the frame halves are lowered again, the bundled rings are released from the frame halves and the rings can be rotated to further bundle other positions or removed from the device.

[0023]

As described above, according to the present invention, the time for assembling the two frame halves to the operating position and disassembling them to the retracted position is extremely short, and the transition space between them is small, so that the binding efficiency is improved. Well, the manufacturing cost of the device is low. Further, it is suitable for binding not only a long product but also a ring-shaped product such as a cable coil.
