Definitions

  • the invention relates to a mechanical handling or tool holding apparatus of the kind defined in the first part of claim 1.
  • Such apparatus is previously known from SE-B-8205268-9, where in a number of profile sections are partially telescopically displaceable relative to one another so as to form an extendable arm, which carries a handling means.
  • Each such profile section or linearly movable element is coupled to an adjacent linearly movable element by means of an endless drive loop.
  • an object of the present invention is to provide an improved apparatus of the kind defined in the first part of claim 1, in such a way that the same profile crosssection can be used in the profile sections constituting the arm, so that one obtains a simple and inexpensive structure, which nevertheless enables repeatable, exact movement of the objects in question.
  • a further object is to permit development from a simple basic structure to a combined system operating with a relatively complex movement pattern.
  • the mechanical construction shall also enable a simple drive with a standard type of electric motor, which can be easily controlled in accordance with a selectable program.
  • the structure shall enable simple exchange of handling or tool holding means for adapting to specific production conditions.
  • the box sections included in the arm in juxtaposition and not telescopically one inside the other, there is obtained sufficient space inside the respective box section for a drive loop, preferably in the form of a toothed belt driven by an electric motor, such as to achieve in a simple manner exact mutual displacement of the juxtaposed box sections.
  • the closed separate box sections will also provide a space for building in power and signal cables to the particular handling or tool holding means.
  • each pair of juxtaposed box sections can be driven separately with its associated motor and drive loop, or a drive loop can be "passively" connected between two box sections separated by an additional box section so that a mutual movement between two sections is transmitted to the additional box section (claim 4).
  • Figs. 1a and 1b illustrate two different cross-sectional shapes for box sections coupled together mutually displaceably and included in an apparatus in accordance with the invention.
  • Figs. 2a, 2b, 3a, 3b, 4a, 4b and 5a, 5b illustrate in side view and cross section, respectively, different embodiments of an arm included in an apparatus in accordance with the invention, the arm having mutually, linearly displaceable box sections with associated drive means;
  • Figs. 6a, 6b, 7a, 7b and 8a, 8b illustrate in side view (6a) front view (7a, 8a) and cross section (6b, 7b, 8b), re spect ively different embodiments of vertically displaceable suspension means for an arm, e.g. according to any one of the of the Figs. 2 - 5;
  • Fig. 9 illustrates in side view a rotatable base, on which a column stand with vertical guidance is arranged, e.g. according to any one of Figs. 6 - 8;
  • Figs. 10a, 10b, 11a, 11b and 12a, 12b illustrate in side view and cross section, respectively, different accessories for connecting to an arm and carrying different gripping means
  • a mechanical handling apparatus in accordance with the invention includes in principle a stand with a preferably horizontally oriented arm fitted to it, this arm carrying handling or toolholding means which are discplaceable in the longitudinal direction of the arm, Cf. Figs. 13 - 18 which illustrate some possible combinations.
  • such an arm comprises at least two box sections, which are juxtaposed, e.g. one above the other, are mutually di splaceable and have complementary sliding glide flanges, the different box sections being mutually displaceable with the aid of one or more motor-driven drive loops, as will be described in more detail below with reference to Figs. 2 - 5.
  • FIG. 1a A preferred embodiment of such box sections is illustrated in Fig. 1a, and a simplified variant is illustrated in Fig. 1b.
  • Fig. 1a is a cross section of two interconnected box sections 1a and 1b, which are mutually displaceable linearly, have exactly the same cross-sectional shape and are produced by extruding an aluminium alloy.
  • each section has a closed, substantially rectangular, preferably approximately quadratic cross section, with two opposing top and bottom walls 10 and 11 and two opposing side walls 12 and 13.
  • the side walls 12,13 are joined at their central portions by a web 14 dividing the interior of the box section la or lb into two chambers 15 and 16.
  • top flanges 17,18 Intrinsic with the corner portions between the top wall 10 and side walls 12,13 there are two top flanges 17,18, each having a side portion 17a, 18a extending substantially as an extension of the respective side wall 12,13, each flange also including an inwardly curved top portion 17b or 18b which, at its free end, has an end portion 17c or 18c tapering obliquely inwards and downwards towards the top wall 10.
  • This end portion 17c or 18c forms, together with a longitudinal ridge 17d or 18d directly opposite it on the upper side of the top wall 10 a pincer-like or C-shaped opening 17e och 18e in cross section, where the openings 17e and 18e are disposed facing towards each other.
  • a bottom flange 19 or 20 projects downwards from the junction between the straight portion 11 of the bottom wall and the respective end portion 11a, 11b.
  • This flange 19 or 20 has a portion 19a or 20a extending perpendicularly downwards from the bottom wall 11, the respective portion curving away substantially at right angles to 19a or 20a and outwards laterally into a bottom portion 19b or 20b, to forming at the free end a solid, substantially cylindrical guide flange 19c or 20c. Both these flanges 19c and 20c are thus directed in opposite directions and are dimensioned to fit with clearance into the respective C-shaped top flange 17 or 18 of a juxtaposed box section, as will be seen from Fig. 1a.
  • the diameters of the flanges 19c, 20c are greater than the pincer-like openings 17e and 18e, so that the guide flanges 19c, 20c are securely retained in the fitted position (the box sections are interconencted by thrusting together in the longitudinal direction.
  • a slide body 21,22 with a substantially annular cross section fitted externally on the respective guide flange 19c, 20c.
  • This slide body 21,22 comprises a plastics material e.g. polyamide, preferably with the addition of a lubricant such as an oil molecule mixture, so that permanent low friction against the surrounding aluminium flange 17,18 is obtained.
  • the slide body 21,22 can suitably comprise a hose which has been slit longitudinally and is thrust onto the respective guide flange 19c, 20c so that the hose surrounds at least the greater part of its circumferential surface.
  • the fit between the sliding guide flanges 17,18 and 19,20 as well the slide bodies 21,22 is such that one guide flange 19c is kept well fixed in position (upwards, downwards and laterally) inside the C-shaped flange 17, while the other guide flange 20c has a slight lateral clearance, as will be seen from the air gap between the slide body 22 and the side portion 18a of the C-shaped flange 18. Unavoidable manufacturing tolerances can thus be compensated and sticking avoided in the mutual linear movement of the box sections 1a, 1b.
  • top and bottom flanges 17,18,19,20 serving as sliding guide surfaces projects a distance upwards and downwards, respectively, from the appropriate section wall 10,11, there is formed a free internal space 23 between the top and bottom walls 10,11 of the interconnected box sections 1a, 1b, between the engaging flanges 17,19 and 18,20.
  • this space 23 is utilized, as well as the internal chambers 15 and 16 for providing protected space to the different parts of one or more drive belts, with the aid of which the mutual, linear displacement of the box sections is achieved.
  • side flanges 24a, 25a, 26a and 24b, 25b, 26b formed on the outside of the respective side wall 12,13, and these flanges together form T-slot s 27a, 28a and 27b, 28b, respectively, which can be utilized for attaching different equipment details, e.g. for fixing a box section to a stand, attaching a drive motor for a drive belt or mutually fixing two box sections arranged at an angle to each other (see drawing Figs. 2 - 18).
  • the box sections 1a, 1b according to fig. 1a Adjacent on to the lower corner edges and side flanges 26a, 26b, the box sections 1a, 1b according to fig. 1a further have downwardly projecting, outer covering flanges 29a or 29b, which have their outer planes coincident with those of the side flanges 24a, 25a, 26a or 24b, 25b, 26b, and exteriorly with play partially surround the adjacent C-shaped top flanges 17 or 18 of the interconnected, respective box section.
  • the inter connected box sections 1a, 1b have common, flat external side surfaces (with slots 27a, 28a, 27b, 28b) and the mutually engaging sliding guide flanges 17,19 and 18,20 lie well protected inside the common side walls.
  • FIG. 1b A modified box section 1c, corresponding to the upper portion (including the intermediate wall 14) of the element 1a or 1b is illustrated in Fig. 1b.
  • Such a section 1c with top flanges 17,18, top wall 10, side walls 12,13 with side flanges 24a,25'aand 24b,25'b and bottom wall 14 can be connected by its upper side to the underside of a box section 1a, 1b according to Fig. la.

  • the necessary openings are drilled or milled from the appropriate side in the box sections for fitting the driving gear wheel and the different idler, jockey and return pulleys 31-35 as well as to enable the passage of the belt in the region of the intermediate wall 14.
  • the end parts 40b and 40d will become extended or foreshortened, the section 1b being displaced linearly in the respective direction in relation to the section 1a.
  • the section 1b can thus be set into any desired position between two end positions corresponding to the location of the point 41 adjacent to the jockey pulley 33 and the location of the point. 42 adjacent to the return pulley 35,
  • a second toothed belt 50 is arranged in the box section 1b to form a practically closed loop. The ends of the belt 50 are thus fastened in adjacents points 43,44 between the jockey pulley 33 and return pulley 35 in the bottom wall 11 of the section 1a.
  • two upper parts 50a and 50b depart through the space 23 to the respective return pulleys 60 and 61, which are freely rotatably mounted at the ends of the section 1b.

  • the belt 50 is not driven by any driving gear wheel and only serves to give the box section 1c a corresponding movement for the mutual movement of the sections 1a and 1b.

  • the gripping means 90' consists in this case of two gripping elements 116a, 116b, each mounted on a swingable arm 117a or 117b.
  • the gripping means is easily exchanged, however, since the holder section 1'c can easily be replaced with another holder section having the desired handling or tool holding means.
  • the arrangement according to Fig. 18 substantially corresponds to the arrangement according to Figs. 17a, 17b.
  • the operating arm 118 is made according to Fig. 2a (in combination with Figs. 10a, 11a or 12a) and in addition the rotatable column stand PS4 can be displaced on rails 119a, 119b along a predetermined path, e.g. on a workshop floor.
  • the inventive concept can be applied in different ways with respect to the implementation of the box sections and the drive means.
  • the box sections can thus be provided with differently formed sliding guide flanges, which can also be placed in a different way.
  • it can be sufficient with a centrally placed flange which is situated upwards, and a complementary formed flange placed downwards on the respective section, the necessary stability being achieved with the aid of sliding surfaces or sliding rails on either side of the respective flange, so that the central flanges ensure that the box sections cannot be moved apart, and the outer sliding guides prevent mutual skewing between the sections.
  • the web 14 can be excluded in simplier embodiments, or can be replaced by several intermediate walls, if it is desired to have a plurality of internal chambers in the box sections, e.g. for guiding a plurality of different drive loops or loop parts.
  • the drive loop or loops can also be replaced by other loop elements other than toothed belts, e.g. cables, chains or some form of belt, providing that these do not stretch.
