Definitions
- the invention relates to a brush tamping machine with a tamping tool having a tip which is pivotable about a first axis between a bundle take-over position and a stuffing position and in the tip of a guide for one, an armature along with the bundle bundle along the guide, at least Having a part of the finished brush forming bristle carrier stuffing tongue.
- Such a brush tamping machine is known from EP 1 803 372 B1.
- a bundle pick-up pivotable about a vertical axis and a tamping tool likewise pivotable about a vertical axis are provided.
- the bundle picker separates bundles from a bristle magazine and transfers them to the stuffing tool immediately behind a point.
- a guide for a tongue is present, so that the tongue leads a recorded bundle together with anchor along the guide to a, at least a portion of the finished brush forming bristle carrier and pushes into an opening in the bristle carrier.
- An anchor can be a metal plate or a wire loop.
- the stuffing tool is pivoted after receiving a scattered bundle in the direction of the bristle carrier, wherein the tongue participates this pivoting movement and penetrates either deeper during this pivotal movement or after reaching the stuffing position in the top, finally to push the bundle together with anchor in the bristle carrier.
- Both the stuffing tool together with the arcuate guide in the tip and the tongue are moved on a circular arc section.
- stuffing tool together with the arcuate guide in the tip and the tongue are moved on a circular arc section.
- stuffing tools with linearly movable stuffing tools with rectilinear tongues, which are moved back and forth transversely.
- Such brush tamping machines must always have faster cycle times.
- the object of the invention is to improve a brush tamping machine of the type mentioned so that they can work with a faster cycle time.
- the brush tamping machine has a tamping tool with a tip which is pivotable about a first axis between a bundle take-over position and a tamping position and which has a tongue stuffing an anchor and bundle along the guide into a bristle carrier in the tip.
- the brush tamping machine according to the invention provides that the guide of the tongue in the tip is linear and that the front end of the tongue relative to the tamping tool in the tamping position performs a linear pushing movement.
- the tongue was a circular arc segment-shaped and the guide in the top also represented a circular arc section
- a linear thrust movement is realized by a linear guide.
- the pivoting movement of the stuffing tool is advantageous over a linear movement, because reversible pivoting movements can be realized with less effort, high precision and above all, high speed.
- the fact that, however, a linear movement is performed by the tongue at its front end, the movement is even faster.
- the linear thrust movement reduces the friction against the guide.
- the movement of the bundle and anchor in the last part of the overall movement is linear, which leads to a smaller space requirement of the front end of the tip and the tongue. If the tongue extends in a circular path even in the last degrees of its movement to the stuffing, there is a disadvantageous lateral movement component when pressing the bundle, which loads the end of the tip and provides additional friction in the guide.
- the bristle carrier may be, for example, an apertured plate later to be joined to the remainder of the brush body a common brush body is joined, or the bristle carrier may also be the brush body itself.
- the tongue can be driven by a preferably own pivot drive, for example, by a separate pivot arm for driving the tongue is present. This means that the tongue moves on the one hand in the region of its driven end along a circular arc path and on the other hand linearly in the region of the guide in the tip.
- the guide for the tongue can sit on a swivel arm of the stuffing tool.
- the axis of the pivot arm of the tongue is also the first axis.
- the stuffing tool can be driven by at least one cam and / or the pivot drive can be driven by at least one cam.
- a cam drive is characterized by a high mechanical stability.
- a possible variant here provides that the cams for the stuffing tool and for the rotary drive of the tongue are rotated by the same camshaft in rotation. This allows for forced synchronization in a very simple way.
- the distance of the front end of the tip from the first axis is at least 200 mm, in particular at least 300 mm, so that the movement of the guide takes place on an extremely large radius of curvature.
- This relatively large pivot radius also ensures that the pivot angle for the pivot arm between the bundle take-over position and the stuffing position is very low, for example, between 2 and 5 °.
- this small swivel angle is already sufficient to complete the complete stroke of the stuffing tool.
- the feed stroke of the stuffing tool may be, for example, only 15-20 mm measured at the leading end of the tip between the bundle take-up position and the stuffing position. This small stroke also ensures high cycle times. In the prior art, corresponding strokes of 25 mm were normal. The percentage reduction of the stroke is therefore enormous.
- the guide in the tip can be substantially linear, e.g. run horizontally.
- This horizontal course which refers to the stuffing position, simplifies the alignment of the parts to each other and, above all, their production, because a linear guide is much easier to produce than a circular segment-shaped.
- the first axis may be a horizontally oriented axis, whereas in EP 1 803 372 B1 the axis was vertically aligned.
- the tongue is in particular formed in one piece and band-like and may for example be made of spring steel.
- a spring steel band makes it possible to drive the tongue without great effort by the rotary actuator.
- As the tongue is moved different regions of the tongue are moved differently, namely, as stated, along a circular path and along a linear guide.
- the stuffing tool can naturally also have a second guide on the back of the tip for the tongue.
- This guide can extend in a linear or circular arc around the pivot axis of the pivot drive.
- One possibility is to guide the tongue on both sides as well as up and down, similar to the guide in the tip.
- the tongue could run along rollers on at least one side and be guided therethrough.
- the tongue is subjected to different types of loading in its different sections and may, for example, have a section guided in at least one guide and a drive-side section.
- the drive-side portion which is the front end of the tongue is opposite, is widened with respect to the guided portion and executed for example as a clamping portion which is supported directly or indirectly on the pivot arm of the tongue.
- the length adjustment of the spread clamping portion in the stuffed position of the tongue can be moved close to the guide, so that this section provides for increased mechanical stability.
- the longitudinal direction of the bristle carrier is oriented in parallel or slightly (i.e., 15 ° -25 °) to the first axis at an angle.
- the pivoting movement of the stuffing tool is thus in a plane perpendicular to the longitudinal direction of the bristle carrier.
- the bust tamping machine according to the invention can be designed without so-called bundle displacer.
- a bundle displacer in the prior art is a separate part lying in front of the tip, which pushes aside the bundles already anchored in the bristle carrier when the next bristle tuft is stuffed adjacent to them.
- the brush tamping machine according to the invention in which the tip itself makes a diving movement and displaced stuffed bristle tufts, such a separate displacer is unnecessary, so that the brush tufting machine according to the invention is simpler and also less complex, so that higher cycle times can be achieved.
- the brush tamping machine according to the invention optionally comprises a bundle picker which feeds individual bundles to the tamping tool, in particular in a horizontal plane.
- the bundle pickup may be a plate-like circular arc segment or a rotating disc which is pivotable about a vertical axis.
- the stuffing tool may be aligned with the bristle carrier such that the leading end of the tip in the direction of the first axis, as viewed from the bundle transfer position to the stuffing position, has a vertically downwardly directed component.
- An optionally provided inclined surface at the top, namely on its underside in the region of the end is directed towards the end obliquely upward and forms a Abweiser configuration for the already stuffed bristle tufts.
- the top may be tapered towards the end, so that the tip tapers towards the end.
- the stuffing tool opposite bristle carrier can be padded so directly. It is thus a kind of rotating tool that can take several positions.
