Definitions

  • Pivotal mounting means are vertically movably mounted on a frame and define a horizontal axis.
  • a rocker arm assembly is pivoted to said mounting means on said axis for a rocking movement through substantially 180 and has an outer end which is remote from said pivotal axis.
  • a gripper is carried by said rocker arm assembly at said outer end and adapted to hold articles.
  • Vertical drive means are provided to adjust said pivotal axis in height during a rocking movement of said rocker arm assembly.
  • Rocking drive means cooperate with said pivotal mounting means to impart to said rocker arm assembly a pivotal movement through 180.
  • connecting means are connected between said vertical drive means and said rocking drive means and serve to impart to said rocker arm assembly a rocking movement in dependence on the vertical movement of said pivotal mounting means.
  • Means are provided to define a reference level which is spaced a predetermined vertical distance above said stack.
  • This invention relates to an apparatus for stacking or unstacking articles, which apparatus provides for a transfer of articles between a conveyor disposed on a predetermined level, and the top of a stack which changes ih height, and which apparatus comprises a rocker arm assembly, which is pivotally movable through substantially 180 and which is movable in height and at one end carries a gripper, and in which apparatus a vertical drive cooperates with a rocking drive.
  • the gripper may consist, e.g., of vacuum cups.
  • a rocker arm assembly consists, e.g., of two parallel rocker arms, between which a cross-beam is provided, which carries the vacuum cups. That cross-beam is rotatably mounted and driven so that the vacuum cups always face downwardly.
  • the rocker arm assembly is moved always to its uppermost position before it is pivotally moved and there is no vertical movement during the pivotal movement. After the pivotal movement, the vertical movement in the other sense is continued by the oneway coupling to the drive chain.
  • That design has the disadvantage that the velocity of the pivotal movement is suddenly increased and that it involves long and changing times of operation because the lifting and lowering movements along the stack take different times in dependence on the height of the stack.
  • pivot bearings or the rocking shaft for the rocker arm assembly is adjustable in height during the rocking movement and the uppermost position of the pivot bearings or the rocking shaft is variable in dependence on a changing reference level above the stack. It will be of special advantage if the pivotal movement and the vertical movement begin and terminate substantially at the same time.
  • the rocker arm assembly is lifted only to the level which is required in view of the instantaneous height of the stack so that excessive vertical movements are avoided.
  • the speed of operation is further increased in that the vertical movement and pivotal movement overlap in time.
  • a high speed of operation is also enabled in that the velocity changes in accordance with a sine function resulting in a gradual acceleration to the highest speed and a subsequent deceleration.
  • important features of the invention reside in the coupling of the vertical drive with the drive means and in the variability of the vertical drive.
  • the change of the vertical drive results in a change of the are along which the gripper is pivotally moved and in a change of the length of the transfer path thereof so that the gripper actually travels only over the distance which is required in each case.
  • the vertical drive consists desirably of a crank member and the length of the crank member is variable in dependence on the height of the stack.
  • the length of the crank member can be selected so that the crank member when moving between two end positions determines the uppermost and lowermost positions of the rocker arm assembly.
  • the effective length of the crank member is adjustable in dependence on the change of the height of the stack.
  • the crank arm comprises suitably a screw or rack along which a nut or pinion, respectively, is movable.
  • This nut or pinion is connected to a drive motor and provides an adjustable stop defining the effective length of the crank member.
  • the nut or pinion is provided with a chain sprocket, which is preferably freely rotatable and around which a vertical drive chain is trained, one end of which is connected to a vertically movable bearing plate for the rocker arm assembly whereas the other end of the chain is connected to that end of the crank member which serves as a permanent point of reference for the change of the length of the crank member.
  • This permanent point of reference ensures that there will always be a fixed reference point for one end position in dependence on the change in length of the crank member.
  • This one end position may be, e.g., the end position for the conveyor, which has a certain overall height.
  • the other end position of the pivotal movement is adjusted in dependence on the changing height of the stack.
  • crank member in the form of a double crank, which extends from its axis 7 of rotation on both sides. This feature enables the provision of a 1:2 transmission ratio regarding the speed and the travel of the rocker arm assembly so that the machine can be designed more economically. Besides, the mass distribution is improved.
  • the double crank has further advantages, which will be explained hereinafter, in special applications.
  • the double crank carries at one end the drive motor for a rotation of the screw and the chain is secured to that end. That end is the point of reference for the fixation of the drive chain.
  • the drive means consist of a crank mechanism and are arranged so that the rocker arm assembly is in one end position of its path of travel when a connecting rod and/or rack which is driven by the crank mechanism and operatively connected to the shaft of the rocker arm assembly is aligned with the crank.
  • This arrangement will result in a change in speed according to a sine function resulting in an automatic deceleration or braking of the movement before each end position.
  • the crank mechanism is provided with a capstan head, to which the rack is linked. That feature will be adopted if predetermined larger distances are to be traveled.
  • a particularly desirable feature resides in that the drive shaft for the crank mechanism and the crank member or double crank of the vertical drive extend vertically and are provided on a cross-member between the vertical guides, and the bearing plates are provided with a drive chain for the crank member or double crank.
  • the resulting arrangement is relatively light in weight and is economically composed of several parts.
  • an abutment of the chain is adjustable at a bearing plate to enable a selection of the reference height over the conveyor means.
  • a handwheel may be provided for this adjustment. It is also preferred to provide for an automatic adjustment of the adjustable abutment in step with the cyclic operation of the machine and for this purpose to provide the adjustable abutment'in the form of a pneumatic or hydraulic actuator, which imparts to the gripper an initial or final stroke when the rocker arms have reached their end positions. In conjunction with the above-mentioned manual adjustment, the actuator would then be adjustable at the bearing plate in a vertical direction.
  • the crank mechanisfn suitably drives a square shaft, which constitutes a drive element for a bevel gearing provided on the stub shaft of the rocker arm assembly, and a drive gear is slidably mounted on the square shaft.
  • a torque-transmitting member comprising four rollers is preferably provided between the square shaft and a housing for the driving bevel gear, which housing carries a stub shaft of the rocker arm assembly, and said four rollers roll on re spective side faces of the square shaft. This results in a particularly low-friction driving connection.
  • the double crank is provided on a horizontal stub shaft and provided with a cam slot, and a sliding block guided in said cam slot is connected by a pivoted rod to a vertically guided member, which is adjustable in height in dependence on the height of the stack.
  • the double crank non-rotatably secured to the rocker arm assembly is connected by a linkage to a drive shaft on which the drive motor is provided and the drive shaft is in mesh with a rack to change the distance from the rocker arm assembly, the vertical drive being connected to a drive wheel in the double crank.
  • the double crank comprises a rack, which meshes with a pinion connected to a drive motor for changing the effective length of the double crank.
  • This pinion meshes also with a rack which is pivoted to the frame.
  • the vertically movable rocker arm assembly is provided with a counterweight, which is guided in the columns and connected by a rope to at least one bearing plate of the rocker arm assembly.
  • This embodiment is characterized according to the invention in that the rope is connected to the rocker arm assembly at a point which is spaced from the pivot bearing thereof and exerts an opposing torque so that the drive power is utilized in a particularly desirable manner.

  • rollers 13, 14 of the bearing plate 6 roll on the corresponding flange 12 of column 4.
  • the columns are connected at the top by a crossbeam 15.
  • the bearing plates 5, 6 are provided with pivot bearings 16, 17 for the rocker arm assembly which comprises the rocker arms 18, 19, which are connected by a crossbeam 20 carrying the vacuum cups 21, 22.
  • a parallel-holding shaft 23 is rotatably mounted in the bearing plates 5, 6 and is provided at its ends with pinions 24, 25, which mesh with racks 26, 27 of the columns 3, 4. As a result, the two bearing plates 5, 6 are constrained to move parallel to each other.
  • a stub shaft 28 extending through the pivot bearing 17 is rotatably mounted in a bevel gear housing 29 and connected to a bevel wheel 30, which meshes with a bevel wheel 31 in the housing 29.
  • the bevel wheel 31 is slidably and nonrotatably mounted on a square shaft 32, which is parallel to the column 4.
  • the bevel wheel 31 is connected to a torquetransmitting member, which is generally designated 33 and by means of a swivel member 34 is mounted on the housing 29 and imparts rotation to the bevel wheel 31 and the square shaft 32.
  • the torquetransmitting member 33 comprises a capstan head, in which four rollers 35, 36, 37, 38 are rotatably mounted, which roll on the sides of the square shaft 32 so that the rotational adjustment of the square shaft is transmitted to the bevel wheel 31 with relatively low friction.
  • the square shaft 32 is rotatably suspended at its upper end in an end journal bearing 39 on the cross-beam and carries a pinion 40 in mesh with a rack 41 (see also FIG. 4), which is held in mesh by means of a backing roller 42.
  • the rack itself is pivoted on a pivot pin 43 in a capstan head 44, which is slidably guided on the cross-beam 15.
  • a cranked connecting rod 45 is also connected to the pivot pin 43 and is rotatably mounted on the pin 46 of a crank 47.
  • the crank 47 is pivotally movable through steps of 180 along an arc of a circle 51 shown in FIG. 3.
  • the vertical drive means of the invention are shown to include a double crank generally designated 53 which is mounted on the same drive shaft 52 carrying the sprocket 50.
  • the double crank extends, e.g., equal distances from the drive shaft 52 on both sides.
  • a screw 55 is rotatably mounted in the double crank and connected to a gearmotor 56, which is operated in dependence on the height of the stack to move a traveling nut 57 from the opposite end 58 as the stack decreases in height.
  • a chain sprocket 59 is freely rotatably mounted on the traveling nut beside an element 60 for guiding the chain to ensure a constant engagement.
  • the chain 62 is guided in the capstan head by two guide sprockets 66, 67 to extend to a chain sprocket 68 disposed adjacent to the column 4.
  • An intermediate chain fastener 69 is provided in an intermediate position and changes the orientation of the chain for meshing through 90 in accordance with the orientation of the guide sprocket 66, 67 and of the chain sprocket 68.
  • the chain end 105 guided over the chain sprocket 68 is secured to an abutment, which in accordance with FIGS. 1 and 2 consists of an end portion of the piston rod 70 of a cylinder-piston unit 71, which is mounted in the bearing bracket 6.
  • the cylinder-piston unit 71 is vertically adjustable along guide rods 72, 73 by means of a screw 74 and a handwheel 75.
  • the height of the support provided by the cross-beam can be adjusted in the directions of the double arrow 76 in FIG. 2 in dependence on the vertical adjustment. This adjustment could also be effected by a corresponding vertical adjustment of a hooklike abutment.
  • the cylinder-piston unit 71 also cooperates with a control means not shown in detail in such a manner that the last approximately 50 millimeters of the vertical movement are added in each end position to the movement of the rocker arm assembly so that a careful handling is enabled.
  • the crossbeam 20 and the vacuum cups 77 can move along the dotted line 78 so that the vacuum cups are raised only to the extent required to lift a top plate from the stack 2 and as a result of the simultaneous displacement of the bearing plates 5, 6 are then moved downwardly and laterally and thereafter downwardly beyond the center of the top of the conveyor 64.
  • This matching of the movements is accomplished in that the double crank 53 has the same drive imparted to it as the crank 47 for the pivotal movement of the rocker arms.
  • the gearmotor 56 can be controlled by stack height sensing means such as photoelectric means 56a for detecting the height of the stack or, alternatively by a step-by-step switch, the steps of which correspond to the height of individual articles of the stack 2.
  • the motion curve 78 indicates that the transfer is effected along a path which is as short as possible.
  • a drive chain 79 is connected between the rocking shaft and the cross-beam 20, which carries the vacuum cups 21, 22 and which is rotatably mounted in the rocker arms 18, 19.
  • the drive chain 79 is trained around a chain sprocket 80 nonrotatably connected to the cross-beam 20 and at its other end is trained around a chain sprocket 81 fixed to the gearbox 29.
  • connecting-rod 45 has an offset portion 82 so that it will not strike on the drive shaft 52 when an end position is assumed in which the crank member 47 is aligned with the cross-beam 15.
  • a counterweight 88 is guided by means of the rollers 84, 85 and the backing members 86, 87 on a flange 83 of the column 3 and is suspended from a rope 89, which is trained around deflecting pulleys 90, 91, 92 and connected to an abutment 93 in the intermediate portion of the rocker arms 18, 19. Because the abutment 93 is spaced from the pivot pins of the rocker arms, which pivot pins extend through the pivot bearings 16, 17, the counterweight 88 exerts a moment on the rocker arm assembly. That moment changes with the angle of the rocker arms relative to the vertical so that a relatively exact balancing of the forces acting on the loaded rocker arms can be accomplished.
  • FIGS. 8 and 9 Another embodiment is diagrammatically indicated in FIGS. 8 and 9.
  • the rocker arm assembly is designated 94 and shown in various positions.

  • the vertical drive is effected in dependence on the rotation of the rocking shaft 98, which is driven by a crank mechanism whereas the gearmotor 102 is controlled in dependence on the changing height of the stack.
  • the control is particularly accomplished with limit switches.
  • Two limit switches are associated with the rocker arms to define the positions over the stack and the conveyor.

  • the limit switches control the described motors and also control the vacuum pump for the vacuum cups to operate in the required sequence.
  • Such control systems can readily be designed in view of the described sequence of motion of the mechanical system. It is pointed out that the drive motor for the vertical adjustment and for operating the rocker arm assembly is a reversible motor, just as the lift-setting motor provided on the double crank for adjustment to the stacking or unstacking operation.
