  • Patent number: 11884197
    Abstract: Automated systems and methods for deployment of mounting tubs that support photovoltaic modules are provided in which a feeder assembly includes a screw thread assembly and a pivot arm. The screw thread assembly has at least one rotatable threaded component, and two such components in exemplary embodiments, positioned within the feeder assembly. The rotatable threaded component supports the stack of mounting tubs and rotates to separate the individual mounting tub from the stack of mounting tubs and lower the individual mounting tub onto the pivot arm. The pivot arm is configured to interact with an individual mounting tub and pivots to dispense the individual mounting tub onto a mounting surface. A sensor may be provided to detect the positions of the individual mounting tubs as they are moved, and a control system communicates with the sensor and the feeder assembly. The feeder assembly and a hopper holding the stack of mounting tubs may be mounted on an autonomous cart.

  • Patent number: 8764374
    Abstract: A separating tool for separating out objects one by one from a stack of objects includes a support base, an assembly plate positioned on the support base, a vertical sliding assembly slidably positioned on the assembly plate, and two opposing clamping members connected to the vertical sliding assembly. Each clamping member includes an engaging plate, a connecting shaft fixed to the engaging plate, and a cam base positioned on the support base. The cam base defines a cam slot, and the connecting shaft slides in the cam slot. A distance from a top end of the cam slot to the engaging plate is less than that from a bottom end of the cam slot to the engaging plate, such that the engaging plates of the two clamping members move together when the engaging plates are moved upwards with the connecting shaft.

  • Publication number: 20140056684
    Abstract: A tray denesting apparatus presents stacks of trays placed upside down within a storage area to a picker mechanism, and separates single trays from the stack of trays. Pneumatically and electrically controlled actuators are employed for handling of the stacked trays. A pneumatic separating device or suction pad may be used to remove individual trays from the tray stack. The Bernoulli principle operates by generating a differential pressure to draw in the tray in a materials handling system. Differential pressure is generated by transporting air through one or more passages in the suction pad to decrease pressure in a chamber. The decreased pressure draws the object towards the pad. After picking up the individual tray a driven rotary device inverts the tray and places the tray onto a tray conveyor located beneath the denesting apparatus.

    Abstract: A feeding device includes a support mechanism, a movable platform, a driving mechanism, a clutching mechanism, and two or more holding mechanisms. The movable platform is movably connected to the support mechanism, and loads feed trays stacked together. The driving mechanism drives the movable platform to move relative to the support mechanism. The holding mechanisms are fixed on the support mechanism, and switch from a first position to a second position. When the holding mechanisms are positioned in the first position, the holding mechanisms grasp one feed tray adjacent to a feed tray at a top of the feed trays, and the clutching mechanism clutches the feed tray at the top of the feed trays. When the holding mechanisms are positioned in the second position, the holding mechanisms separate from the feed trays.

    Abstract: A tray handling apparatus comprises a plurality of guides, a chuck device, a linear movement device, and a rack and pinion device. A space defined by the erected guides is used to hold a tray stack. The chuck of the chuck device is located at the center position of the bottom area of the space. The linear movement device is used to move the chuck relative to the guides. The rack and pinion device is used to cause the guides to move symmetrically. When an operator moves any one of the guides, the other guides move symmetrically and the center of the bottom area of the space surrounded by the guides remains at the same location during the movement of the guides. The operator does not need to adjust the position of the chuck if the positions of the guides are changed.

  • Publication number: 20110229297
    Abstract: A tray denester for separating individual trays from a stack. The tray denester includes a product carrier plate that is movable toward and away from the discharge end of a product magazine. The product carrier plate includes a pair of air nozzle assemblies. As the product carrier plate moves toward the discharge end of the magazine, the air nozzle assemblies are activated to create a low-pressure zone along the product carrier plate. When the product carrier plate reaches the discharge end, an escapement mechanism releases the stack of trays. As the stack of trays is released, the low-pressure zone separates one of the trays from the stack. The separated tray contacts the product carrier plate and is removed from the stack. Each of the air nozzle assemblies is adjustable along the product carrier plate to vary the position of the air nozzle assemblies based upon the specific tray design.

    Abstract: A vacuum picker apparatus for cups includes a vacuum picker head with concave surface areas, each being preferably ½° reverse angle, and each surface area having a hole therethrough that allows for a vacuum to be formed at the picker head. When the vacuum is formed, the side wall of the cup is drawn, inside the overall circumference of the head at each concave surface area to provide for an effective seal to hold the cup to the picker head, which reduces deformation of the cup and facilitates its extraction for further processing. A protective ring or skirt at the picker head has spaced apart notches through which apertures are formed to direct a thrust of air against the stack to force the stack away from the individual cup being denested. The dual action of the vacuum picker apparatus removes an individual cup from a stack of cups and forces the stack away from the cup to facilitate removal of the individual cup from the stack.

  • Patent number: 6357599
    Abstract: A machine comprising a base and an elongated cradle pivotally mounted on the base is used to facilitate separation of nested tapered drums from a stack. With the cradle in an upright position, the machine is moved toward the stack to embrace the stack in the cradle. A pair of clamps on the cradle embrace and grip successive drums at a lower end of the stack, and then the cradle is moved to a lay-down position, carrying the stack with it. A first clamp of the pair, gripping a first drum, is moved away from a second clamp of the pair and then releases the first drum so that it can be separated from the second drum. The first clamp is then moved toward the second clamp. The second clamp releases the second drum, and the laid-down stack is moved along the cradle to align the second drum with the first clamp and a third drum in the stack with the second clamp. The first and second clamps then grip the second and third drums, respectively, and the first clamp is again moved away from the second clamp.

  • Patent number: 6354792
    Abstract: An IC receiving tray storage device is provided which is capable of securedly identifying the category of the tested ICs sorted for each category and received in the corresponding tray in the unloader section after end of test. Mounted to the tray storage is a casing comprising a generally rectangular base plate and a plurality of outer walls standing substantially upright and separately from each other on the base plate. A category identifying indicator is attached to at least one outer wall of the casing. This category identifying indicator indicates the category of ICs received in the tray. Also, in the base plate of the casing is formed an opening through which vertically movable unit is free to move. By the category identifying indicator, the category of the tested ICs received in the tray can be easily confirmed after the tray storage device has been taken out from the IC handler.
