Definitions

  • the invention relates to an apparatus for manufacturing a metal handle and placing this handle on a bucket.
  • Apparatuses for providing plastic buckets with a metal handle are known per se from practice.
  • the known apparatuses are so-called dedicated machines specifically manufactured for a specific bucket with an associated specific handle.
  • the machines cannot be readily made suitable for processing other types of buckets with differently shaped handles.
  • the invention provides an apparatus comprising a bucket moving module for feeding handleless buckets and carrying away buckets provided with handles, a handle manufacturing module for manufacturing handles from metal rod elements, a rod feeding module for feeding metal rod elements to the handle manufacturing module and a handle mounting module for mounting a handle on a handleless bucket.
  • a bending head of the handle manufacturing module can be readily exchanged for another bending head suitable for manufacturing handles of a different form and/or dimension.
  • the modular construction therefore provides the possibility of a high degree of flexibility.
  • the rod feeding module is adjustable for the feeding of rod elements of different lengths
  • the handle manufacturing module is adjustable for the manufacture of handles of different dimensions and/or shapes
  • the bucket moving module is adjustable for the feeding and carrying away of buckets of different dimensions.
  • the module can be adjusted for the processing of, for instance, rod elements of different lengths and buckets of different dimensions and/or shapes.
  • the handles can be provided with a grip.
  • the apparatus should be provided with a grip feeding module for feeding grips to the handle manufacturing module.
  • the handle manufacturing module comprises two knob-forming heads which are arranged opposite each other and are each rotatable about a common axis of rotation and are arranged for axial movement in the direction of the axis of rotation, which knob-forming heads are each provided with a knob-forming element and at least one supporting element, which knob-forming element is provided with a forming surface which intersects the axis of rotation and makes an angle with the axis of rotation, while the at least one supporting element is intended for abutment on the outer surface of the rod element for taking up forces exerted on the rod end by the forming surface.
  • a knob of excellent quality will be very gradually formed at the end of the rod.
  • the knob has a very smooth surface, so that placement of the rod in the bucket will be readily effected.
  • the outer surface of the rod need not be forcefully clamped, so that damage to this outer surface will not occur.
  • the knob-forming process proceeds so gradually and with so little force that no metal particles become detached from the rod elements and, moreover, the use of hydraulic oil for the purpose of generating great forces can be left out.
  • the rod element was bent in a specific phase of the process to form a handle.
  • metal has elastic properties.
  • the rod should be bent during the bending operation with a stronger curvature. After this bending operation the rod will slightly spring back as a result of the elasticity.
  • the selection of the stronger curvature was such that the spring-back resulted in a handle with the intended curvature. This is of great importance because the curvature defines the distance between the two ends of the rod. If this distance does not fit the diameter of the bucket, it will not be possible for the handle in mounted condition to swing easily with respect to the bucket.
  • the handle manufacturing module is provided with a bending unit, by means of which the rod element is bent into a handle, which bending unit comprises a relaxation arrangement designed to carry out a plurality of plastic deformation operations, which deformation operations eventually effect no definitive deformation but only bring about a relaxation of the stresses existing in the bent rod element as a result of the bending of the rod element carried out by the bending unit.
  • the plastic deformations carried out by the relaxation arrangement are undone in subsequent plastic deformation operations by the same relaxation arrangement.
  • the stresses existing in the handle as a result of the bending will largely be removed.
  • This has the great advantage that when bending the rod into a handle the curvature can be selected which the handle should eventually have. It is a fact that the elastic spring-back properties of the rod bent into a handle are removed under the influence of the plastic deformation operations carried out by the relaxation arrangement.
  • the exemplary embodiment of an apparatus according to the invention described hereinafter is especially intended for buckets as shown in Figs. 1 and 2.
  • the bucket comprises a bucket body E and a handle H.
  • the handle H is attached to the bucket edge R of the bucket body E.
  • a grip G may be attached to the handle H, which is shown in Fig. 1.
  • the handle H is provided at the free ends with knob-shaped thickenings K which ensure that the ends of the handle H cannot slide out of the bucket edge R.
  • the handle H is formed from a metal rod S and is placed on the bucket body E after forming the knob-shaped thickenings thereon and carrying out the different bending operations. All these operations are carried out by means of the apparatus according to the invention, an exemplary embodiment of which is shown in Figs. 3 and 3A in front and side view, respectively.
  • the present exemplary embodiment shows an apparatus comprising a bucket moving module for feeding handleless bucket bodies E and for carrying away buckets E provided with handles H.
  • the apparatus further comprises a handle manufacturing module 150-180 for manufacturing handles H from metal rod elements S.
  • the apparatus comprises a rod feeding module 90-110 for feeding metal rod elements S to the handle manufacturing module 150-1250.
  • a handle mounting module 260 is provided for mounting a handle H on the handleless bucket body E.
  • Figs. 4 and 4A are a front and a side view of the frame 10 of the apparatus.
  • Figs. 5 and 5A are a similar view as shown in Figs. 4 and 4A, in which the rod feeding module 90-110, a part 150-180 of the handle manufacturing module and the grip feeding module 120-140 for feeding grips G to the handle manufacturing module 150-180 are shown.
  • Figs. 5 and 5A are only for the purpose of showing the positioning of these parts in the frame 10. To accurately show the above parts, reference is made to Figs. 6, 6A, 6B, 7A, 7B, 7C, 8, 9A, 9B, 9C, 10, 11, 11A, 12, 12A and 13, to which reference is made in the following description.
  • the rod feeding module 90-110 comprises a lifting apparatus 90 provided with imbricated plate elements 100.
  • a drive 101 By means of a drive 101 the positions of the imbricated plate elements 100 can be shifted with respect to each other. A number of different positions is shown in Figs. 7A-7C.
  • a rod S can be gradually lifted by the mutual movement of the imbricated plate elements 100.
  • Such a manner of lifting rod elements has the special advantage that at the upper side of the lifting apparatus 90 only one rod element is fed at a time. It is a fact that the width of the upper edge 105 of the imbricated plate elements 100 is such that only one rod S can be placed thereon.
  • each disk 110 is provided with recesses 111 in which a rod S can be received. The disk 110 rotates intermittently, so that a recess 111 is always ready for receiving a next rod element S.
  • the rod feeding module 90-110 comprises two lifting apparatuses 90, 90', the mutual distance of which is adjustable, so that rod elements S of different lengths can be processed. It is self-evident that when adjusting the mutual positions of the lifting apparatuses 90, 90' the disks 110 also have to be adjusted by moving them along the shaft 112.
  • the grip feeding module 120-140 also comprises a lifting apparatus 120, which is provided with imbricated plate elements 130.
  • the operation of this lifting apparatus 120 is comparable to the lifting apparatus 90 of the rod feeding module 90-110.
  • Fig. 6B is the side view of the grip feeding module, which clearly shows that the imbricated plate elements 130 thereof have a width larger than that of the rod feeding module 90-110.
  • At the upper side of the lifting apparatus 120 of the grip feeding module there is also a disk 140 for receiving grips G.
  • the imbricated plate elements 130 and the mutual position changes thereof are once more clearly shown in Figs. 9A-9C.
  • a grip G rests on the upper side 135 of a plate element 130 and is transferred from the upper edge 135 of a lower plate element 130 to the upper edge 135 of a higher plate element 130.
  • Fig. 10 further shows the receiving disk 140 for the grips G.
  • This receiving disk 140 is provided at its circumference with recesses 141, each of which can receive one grip G.
  • this handle manufacturing module is provided with two knob-forming heads 150, 160, by means of which the knob-shaped thickenings K can be formed at the ends of the rod-shaped element S.
  • the disks 110, 140 bring a rod-shaped element S with or without a grip G mounted thereon into a position which is in line with the axis of rotation of the knob-forming heads 150, 160.
  • a clamp 165 see Figs. 11, 11A
  • the rod element S is pressed against the disks 110 so as to prevent co-rotation and axial movement of the rod element S during and after the knob-forming process, respectively.
  • the knob-forming heads 150, 160 are arranged for movement in the axial direction A and are rotatable.
  • the clamp 165 is energized by a piston/cylinder assembly 166 or by exerting a spring force.
  • Fig. 12 shows the knob-forming head 150 in detail.
  • the knob-forming head 150, 160 is provided with a knob-forming element 170 which is bearing-mounted in the rotatable head 150 for rotation.
  • the knob-forming element 170 is provided with a forming surface 175 which intersects the axis of rotation L of the head 150 and makes an angle therewith.
  • the head 150, 160 is provided with supporting elements 180 intended for abutment on the outer surface of the rod element S to take up the forces exerted on the rod end by the forming surface 175.
  • a thickening K at the end of the rod S By rotation of the head 150 and exertion of a slight axial force by moving the head 150 in the axial direction A, there will be formed, as shown in Fig. 13, a thickening K at the end of the rod S.
  • the head 150 is driven by a motor 152 via a belt transmission 151.
  • a separate motor 162 For the head 160 there is provided a separate motor 162.
  • the axial movement of the knob-forming heads 150, 160 is always oppositely directed and is effected by a motor 153 which moves the knob-forming heads 150, 160 in the axial direction by means of two curves via two control rods.
  • the rod is picked up from the recesses 111 in the disks 110 by means of a transfer mechanism 280 and transferred to a bending unit 190-250.
  • the position of the bending unit 190-250 in the frame is shown in Figs. 14 and 14A, while the structural details of the bending unit 190-250 are shown in Figs. 15, 15A, 16, 16A, 16B, 18, 19 and 20.
  • the effect of the bending operation is shown in Fig. 17.
  • the transfer mechanism 280 for moving a rod S from the disks 110 to the bending apparatus 190-250 is shown in Figs. 21, 21A and in more detail in Figs. 22, 22A.
  • the transfer mechanism (see Fig. 22) is provided with four clamps 281 mounted on a shaft system 82 within which there is included a control shaft 285, which control shaft 285 can be rotated with respect to the outside shaft 282 by means of a piston/cylinder assembly 286.
  • the inside shaft 285 is actively connected with the jaws 287 of the clamps 281, so that they can be opened and closed.
  • this entire assembly is mounted on a sledge 284 which is arranged along a guide 283 for up and down movement.
  • Figs. 22, 22A show the clamps 281 in an uppermost position in full lines and in a lowermost position in dotted lines. From the lowermost position the clamps 281 take up the rod from the recesses 111 in the disks 110. Then the clamps move up into the uppermost position, so that the ends of the clamps are received in bending heads 200 of arms 190 of the bending unit 190-250.
  • the arms 190 are movably connected with a frame part 191 (see Fig. 15). This connection enables a horizontal movement of the arms 190 toward and away from each other.
  • bending heads 200 Arranged in the arms 190 are bending heads 200, by means of which the ends of a rod S can be bent through 90°.
  • Figs. 16, 16A, 16B show a single arm 190 in more detail.
  • the bending head 200 is provided at a free end with a groove in which a rod end can be received.
  • the bending head 200 is bearing-mounted in the arm 190 for rotation and is driven by means of a toothed belt 193 which is driven by means of a piston/cylinder assembly 192.
  • the piston/cylinder assembly 192 and the toothed belt 193 are included in the arm 190.
  • the belt 193 is moved, which results in a rotation of the bending head 200.
  • Suspended from the frame plate 192 is further a bending unit 215 arranged for movement in the vertical direction.
  • the bending unit 215 is provided with a guide 216, the height adjustment of which takes place by means of an electric motor 244 and an associated toothed belt 218.
  • the bending unit comprises a bending head 219 having a radius of curvature corresponding to the intended radius of curvature of the handle H. The manner in which the rod S is bent into a handle H is shown in Fig. 17.
  • Fig. 17G is a front view of the bending head 200 from the right side of Figs. 17A-F. Clearly visible is the insertion groove 201. When placing the rod S in the head, it is placed in the bending head 200 via the insertion opening of the groove 201. It clearly appears from the left and right side views of the bending head 200 (Figs. 17I and 17H) that the insertion groove 201 has a key hole form. From the cross-section on the line J-J from Fig. 17H, which cross-section is shown in Fig.
  • the bending heads 200 are rotated an eighth of a turn, so that an engagement based on friction starts between the bending heads 200 and the rod.
  • the bending unit 215 is moved down, while at the same time the arms 190 are moved toward each other.
  • a further rotation of the bending heads 200 takes place, which is clearly shown in Figs. 17C, 17D and Figs. 17K2, 17K3.
  • the bending heads 200 rotate the fourth of a turn further, so that the state of Figs. 17E and 17K4 is obtained.
  • the bending heads are rotated back through 45°, so that the rod S can be moved in the axial direction of the bent end thereof out of the groove 201 in the bending head 200 and can then be transferred to the bucket.
  • the abutting face 220 against which the knob-shaped thickening K of the rod S is drawn during the bending process the bending operations of the rod and the bending of the ends thereof take place under tensile stress.
  • this tensile stress prevailing in the rod very taut bends can be bent in the rod S. If in this stage the bent rod S were removed from the bending heads 200 of the arms 190, it would partially bend back in connection with the stresses existing in the rod. This is prevented by providing the forming head 215 with a relaxation arrangement.
  • the relaxation arrangement is shown in more detail in Figs. 18, 19 and 20.
  • the relaxation arrangement of the bending head 219 comprises a plurality of juxtaposed abutting elements 220, which are provided with a receiving slot 230 for partially receiving therein the bent rod element S.
  • the abutting elements 220 are movably arranged, in the present case in a direction perpendicular to the plane in which the rod S is bent.
  • Each abutting element 220 is further provided with a cam path groove 240 with a wide inlet side and a wide outlet side.
  • the relaxation arrangement is provided with a rotatably driven disk 241, which carries a plurality of cams 250 staggered with respect to each other in a direction perpendicular to the plane in which the bent rod is located.
  • the cams 250 successively move through the cam path grooves 240 of the juxtaposed abutting elements 220, so that the cams 250 successively impose a movement on the abutting elements 220.
  • the rod S is locally subjected to plastic deformation, which deformation operations do not effect a definitive deformation but only bring about a relaxation of the stresses existing in the bent rod element S as a result of the bending of the rod element S accomplished by the bending unit.
  • Fig. 19 is a sectional view in which the disk 241, the abutting elements 220 and the cams 250 are visible.
  • Fig. 20 is a developed view of the abutting elements during the deformation process. In this developed view it is clearly visible that the deformation on the left in the figure is still great, while the deformation on the right in the figure is practically nil.
  • the bending head 219 from Fig. 15 differs from the bending head 219 from Fig. 15 in that the former is suitable for the manufacture of handles H without grip G, while the latter is suitable for the manufacture of handles H with grip G.
  • the bending head 219 from Fig. 15 is provided with a pressing block 217 which is movable up and down with respect to the bending head 219, and by means of which the handle H can be provided on both sides of the grip G with a bend to limit the lateral movement of the grip G.
  • Fig. 15A further shows the motor 242, by means of which the disk 241 is driven.
  • Fig. 15A shows a motor 243, by means of which the pressing block 217 is movable in the vertical direction.
  • a handle mounting module 260 (see Figs. 23-25) provided with two handle mounting heads 265 takes up the handle from the arms 190 of the bending unit 215.
  • the position of the handle mounting module 260 with respect to the frame is clearly shown in Figs. 23, 23A.
  • Fig. 25 is a side view of the handle mounting module 260 in more detail
  • Fig. 25A is a top view of the handle mounting module 260.
  • the two handle mounting heads 265 are connected with the ends of swiveling arms 266.
  • the handle mounting heads 265 are each provided with an outer cylinder 267 and an inner cylinder 268, see Figs. 26A-26E.
  • the outer cylinder 267 is rotatable with respect to the inner cylinder 268.
  • the outer cylinder 267 is provided with a straight longitudinal groove
  • the inner cylinder 268 is provided with a helical groove.
  • Figs. 26A-26E show the manner in which the handle is taken up from the arms 190 of the bending unit and then placed again in the edge R of the bucket E, in which two holes are provided for receiving the ends of the handle H.
  • the ends thereof are not only pressed toward each other in the axial direction, but by slightly swiveling the outer cylinder 267 backwards and forwards a kind of levering movement is effected, which causes the knob-shaped thickenings K to move more easily through the openings in the edge R of the bucket E.
  • the bucket E should be accurately positioned before the handle can be mounted therein.
  • the apparatus is provided with a bucket moving module, which will hereinafter be discussed in more detail with reference to Figs. 27-40.
  • Figs. 27 and 27A are again a front and a side view of the above-discussed modules with omission of the handle mounting module 260.
  • the rod elements S are located in a magazine 97 near the lower side of the lifting apparatus 90, while the grips G are stored in a reservoir 129, which is provided with an inclined bottom, so that the grips G are passed to the lower side of the lifting apparatus 120.
  • Figs. 28-40 show the different parts of the bucket moving module and the positions of these parts with respect to the frame 10.
  • the bucket moving module 20-80 is provided with a feeding conveyor 20, by means of which a bucket E can be introduced into the apparatus (see Figs. 28 and 28A).
  • a lifting apparatus 30 Arranged above the free end of the feeding conveyor 20 is a lifting apparatus 30 (see Figs. 29, 30), by means of which a bucket located on the feeding conveyor 20 can be lifted.
  • the lifting apparatus 30 is provided with a suction plate 31 which is connected via an arm 32 with a vertical guide 33. Connected to the suction plate 31 is a suction line 34, by means of which a reduced pressure can be created below the plate 31 so as to suck a bucket E against it. Instead of the suction plate 31, there can also be used a suction pad engaging the bottom of the bucket E.
  • this lifting apparatus 30 the bucket E can then be placed on a supporting plate 40 arranged for movement in the horizontal direction, the position of which with respect to the frame 10 is clearly shown in Figs. 31 and 31A.
  • a top view of the plate 40 movable in the horizontal direction with the associated guide 41 is shown in Fig. 32.
  • the plate 40 will be in a right-hand position when the lifting apparatus 30 places a bucket E thereon. Subsequently, the plate 40 moves to a left-hand position shown in Fig. 31, so that the bucket is approximately in the middle of the apparatus. At that place the apparatus is provided with a rotatable centering plate 50 (see Figs. 33, 34, 35), which is arranged for up and down movement.
  • Figs. 33, 34, 35 The position of the vertically movable, rotatable centering plate 50 with respect to the frame 10 is clearly visible in Figs. 33 and 33A.
  • Fig. 34 is a side view of the centering plate 50. It is clear that via the guide 51 the plate is movable up and down in the vertical direction.
  • the rotational position of the plate is controlled by means of a toothed belt 52.
  • a vacuum line is also connected to this centering plate 50, so that the bucket E can be sucked against it.
  • Rotation of the bucket E is necessary to enable bringing the holes in the edge R of the bucket E into such a position that the ends of the handle H can be pressed into them.
  • there can be used an electric eye which observes the holes, and which, on the basis of this measurement, transmits to the control of the motor, for the purpose of rotation of the centering plate 50, such a signal that the holes in the edge R reach the desired position.
  • the centering plate 50 is provided with an edge falling within the circumferential edge R of the bucket E, so that the edge of the centering plate 50 prevents the deformation of the bucket E as a result of the force exerted thereon when placing the handle H.
  • the centering plate 50 moves down again, and the vacuum is released, so that the bucket E is placed again on supporting plate 40 arranged for movement in the horizontal direction.
  • This supporting plate 40 is then again in the right-hand position, so that meanwhile a second bucket can be placed on the right side of the supporting plate 40.
  • the supporting plate 40 arranged for movement in the horizontal direction again moves to the left, and the bucket E located on the left side of this plate can be taken up by a stacking unit 70, the position of which with respect to the frame 10 is shown in Figs. 36 and 36A.
  • This stacking unit 70 which is shown in detail in Figs. 37 and 38, comprises two supporting arms 71. These supporting arms 71 are connected with an inclined longitudinal guide 72 so as to be freely movable. Both longitudinal guides 72 and the supporting arms 71 connected therewith are connected with a plate 73, which is connected with a longitudinal guide 74 for up and down movement.
  • the supporting arms 71 have a slightly inclined run-on edge 75. When the plate 73 moves down, the supporting arms 71 at a given moment touch the upper edge R of a bucket E located on the plate 40. When the plate 73 moves further down, the supporting arms 71 will move out along the inclined guides 72, until they have such a position that they can pass the edge of the bucket E.
  • the plate 73 will move a little further down and then be moved up again. With this upward movement the supporting arms 71 will automatically assume the lowest possible position on the guides 72, while abutting on the wall edge of the bucket. When the plate 73 moves up further along the guide 74, the supporting arms 71 will move out along the inclined guides 72, until they have such a position that they can pass the edge of the bucket E. The plate 73 will move down a little further and then be moved up again. With this upward movement the supporting arms 71 will automatically assume the lowest possible position on the guides 72 while abutting on the wall edge of the bucket.
  • the supporting arms 71 When the plate 73 moves up further along the guide 74, the supporting arms 71 will at some moment contact the lower side of the edge R of the bucket E and lift the bucket E when the plate 73 moves up further. By repeating these operations a stack of buckets E is automatically formed. This stack of buckets is lifted by the supporting arms 71, until the stack has such a height that it can be carried away.
  • the apparatus is provided with an outlet conveyor 80, which is shown in Figs. 39 and 39A.
  • the plate 73 moves down completely via the vertical straight guide 74, until the lowermost bucket of the stack rests on the transport surface of the outlet conveyor 80.
  • there may be provided two energized piston/cylinder assemblies 76 which can temporarily push the supporting arms 71 to an outermost position.
  • the different parts thereof can be readily adapted to the shape and dimensions of the buckets, rod elements, grips to be processed, and handles to be formed. This therefore results in a universal apparatus delivering buckets with handles of high quality.
  • the bent ends may have a smaller length, which is favorable for the width of the edge R of the bucket E, which is necessary to receive the ends of the handle H. Accordingly, by means of the apparatus according to the invention buckets E can be manufactured with a relatively narrow edge R.
