Definitions
- the invention relates to a strapping device for strapping an object with a thermoweldable plastic band around it, according to the preamble of claim 1.
- Strapping tools of the type mentioned are known several times, for example from EP-0744342. They have a tool part and a support part, the opposite and mating contact surfaces of which are structured in a tooth-like manner in order to be able to grip the plastic strip as effectively as possible during tensioning and friction welding.
- the disadvantage here is that it is complex and costly to produce the desired tooth-like structuring on the concave contact surface of the contact part.
- the object of the invention is to provide a generic strapping tool which does not have the disadvantage mentioned.
- the concave support surface of the support part is composed of a plurality of sections lined up, namely of the plurality of outer sides of the holding jaws, which, compared to the prior art, allows smaller areas of the concave support surface to be processed individually and the processing effort to be reduced accordingly .
- the holding jaws are each provided with an essentially flat and rectangular outer side, the edges of this outer side being parallel to the axis of rotation and the swivel axis are.
- Such holding jaws can then be inexpensively machined on a flat outside and can be structured with optimal toothing.
- they can be strung together and fastened on the shoe during assembly such that they come together to lie on the lateral surface of a prism with the axis of rotation and the axis of rotation essentially parallel.
- the holding jaws manufactured and assembled in this way together form a support surface of the support part which approximately matches the generally cylindrical tool surface of the tool part, which, together with the optimal toothing, allows the overlapping band parts introduced between them to be gripped and held well and high clamping forces applied to them.
- FIG. 1 shows a side view of a strapping device according to the invention together with a view of a partial area of the strapping device in approximately six times magnification (magnifying glass view);
- FIG. 2 shows a sectional view of the strapping device along the line A-A of FIG. 1 together with a view of a partial area of the strapping device in an approximately one and a half magnification (magnifying glass view);
- FIG. 3 shows an exploded perspective view of parts of the strapping device to illustrate the fastening and arrangement of holding jaws on the strapping device;
- FIG. 4 shows an exploded perspective view of the holding jaws of FIG. 3 in a magnification which is approximately twice that of FIG. 3;
- Fig. 5 is a plan view of a in the magnifying glass view of the 1 shows the broken-off part of the U-maturation device in a magnification approximately one and a half compared to the magnifying glass view to illustrate the structuring and mutual arrangement of the holding jaws;
- FIG. 6 shows the strapping tool in the same view as in FIG.
- FIG. 7 shows the strapping tool in the same view as in FIG.
- the strapping device according to the invention shown in the figures is used for strapping an object with a plastic band around it and is described using an exemplary embodiment, it being understood that the invention is not to be limited to this exemplary embodiment.
- the strapping device shown comprises, on a housing 1, a device 2 for tensioning a thermoweldable plastic band 3 and for friction welding two overlapping band parts 4 and 5 of this plastic band 3.
- the device 2 comprises a tool part 7 which can be rotated and driven about an axis of rotation 6 and which is a has generally cylindrical tool surface 8.
- the device 2 comprises a support part 9, which in turn is provided with a support surface 10 which faces the tool part 7 and extends over a sector of the tool jacket surface and generally surrounds this.
- the bearing surface 10 and advantageously also the tool surface 8 are structured in order to be able to grip the plastic strip 3 as effectively as possible.
- the contact surface has 10 has a special toothing, which is described in more detail below and is best seen in FIGS. 3, 4 and 5.
- the tool part 7 and the support part 9 can be pivoted about a pivot axis 12 with the aid of a lever 11, this pivot axis 12 being parallel to the axis of rotation 6.
- the support part 9 comprises a separate shoe 13, which is designed in several parts.
- the shoe 13 is composed of three holding jaws 14, 16 and 18 that are angularly lined up around the axis of rotation 6. These holding jaws 14, 16 and 18 have respective outer sides 15, 17 and 19 which adjoin one another at edges 20, 21, 22, 23 and together form an outer side 24 of the shoe 13 and thereby also the contact surface 10 of the contact part 9.
- the edges 20, 21, 22, 23 lie parallel to the axis of rotation 6 and to the pivot axis 12, and the outer sides 15, 17 and 19 lie on a prismatic lateral surface surrounding the tool lateral surface 8.
- the support surface 10 of the support part 9 thus formed approximates the cylindrical tool surface 8 of the tool part 7 and allows enough to grasp and hold the overlapping band parts 4 and 5 of the plastic band 3 inserted between them.
- FIGS. 3 and 5 The attachment of the shoe 13 or the holding jaws 14, 16 and 18 on the support part 9 is best seen in FIGS. 3 and 5.
- the holding jaws 14, 16 and 18 lie side by side and snugly against one another, the edges 20, 21, 22, 23 lying parallel to the axis of rotation 6 and the pivot axis 12 each representing the longer edges of the rectangular outer sides 15, 17 and 19 are.
- the holding jaws 14, 16 and 18 each end on both sides with projections 26, which each engage under one of two clamping jaws 27 and 28.
- These jaws 27 and 28 are fastened to the support part 9 by means of screws 29, guide pins 30 and washers 31 and in turn hold the holding jaws 14, 16 and 18 when the screws 29 are tightened on the support part 9.
- the processing of the outer sides 15, 17 and 19 of the holding jaws 14, 16 and 18 leads to the formation of a structuring, for example, like that which is best shown in FIGS. 3, 4 and 5.
- the flat outer sides 15, 17 and 19 of the holding jaws 14, 16 and 18 allow and facilitate the machining of the holding jaws by milling or grinding in different directions essentially parallel to the outer sides and at any angle to the longer edges 20, 21, 22, 23. In this way the outer sides 15,
