The present disclosure relates to a test tube capper-decapper device comprising an arrangement for switching an array of cap grippers comprising at least three cap grippers between a one-dimensional array of cap grippers and a two-dimensional array of cap grippers, an arrangement for being comprised within a test tube capper/decapper device, whereby it is made possible to switch an array of cap grippers comprising at least three cap grippers between a one-dimensional array of cap grippers and a two-dimensional array of cap grippers by action of a switch on the array of cap grippers, whereby the versatility of the test tube capper/decapper device can be increased.

In a hand-held capper/decapper device, cap drivers in an array are driven by an array of rotary motors that drive the cap drivers in forward and reverse rotary directions to cap and decap caps from threaded receptacles. A common linear drive drives ejector pins through the centers of cap drivers to eject caps from the cap drivers. Single button operation is enabled by a controller that responds to press and release of a control button to alternate between decap and cap functions. The cap function finishes with ejection by extension of an ejector pin. An ejector button may also be provided for ejection without rotation of cap drivers. The cap drivers float against compression springs that apply axial force to the cap drivers. Ejection of the caps is staggered to reduce force required. Replaceable cap drivers designed to corresponded to cap designs are supported in a removable cartridge that is retained on a hand-held housing by magnets.

An apparatus for automated capping and de-capping of test tubes having an ejector pin system for individualized cap ejection.

A system and method for a self-actuating, mechanically-biased container restraint. The system requires no computer-aided control or timing, nor is any external power source needed, other than the force exerted as a container is inserted into the restraint. The system relies upon an assembly including mechanically-biased pivoting levers, each of which has a horizontal element and a vertical element. All actuation occurs as the base of an inserted container comes into contact with the upper surface of the horizontal elements of multiple pivoted levers positioned at the base of a channel adapted to serve as a guide for the inserted tube. The levers are biased in this elevated position by mechanical means, such as a spring. As the inserted tube presses the horizontal members downward, the top portions of the vertical members are pivoted inward toward the container's exterior. Friction pads situated upon the interior surface of each vertical element are brought into contact with the exterior of the container, thereby gripping it. This gripping action holds the container with sufficient friction to permit the removal or attachment of a screw cap. Further embodiments of the invention include a mechanically biased platform supporting the channel and the pivoting levers. This base is biased and positioned to permit the channel and the pivoting lever assembly to be translated downward against the force biasing the platform and translate through the body of the container restraint. This further advancement of container, the channel and the lever assembly cause the pivoting levers to assume fully engaged gripping positions, and brings the vertical elements of the levers (and flexible friction pads upon them) into full upright positions. In this position the friction pads apply a maximum static friction force to the exterior of the container.

A bottle cap opening and closing device and an experimental apparatus. The bottle cap opening and closing device includes a base, a bottle body clamping mechanism used for clamping a bottle body, a first buffer mechanism arranged between the bottle body clamping mechanism and the base, a bottle cap clamping mechanism arranged opposite the bottle body clamping mechanism and is used for clamping a bottle cap, and a rotation driving mechanism drive-connected to the bottle body clamping mechanism and drives the bottle body clamping mechanism to rotate relative to the bottle cap clamping mechanism to enable the bottle body and the bottle cap to be relatively tightened or separated from each other.

A chemical drum replacement apparatus includes an automated robotic assembly configured to attach or detach a drum cap and a coupler module to or from a chemical drum and a transfer robotic assembly configured to transfer the chemical drum, where the automated robotic assembly includes a travelling module configured to move the automated robotic assembly, a manipulator on an upper surface of the travelling module, and a gripper at an end of the manipulator, the gripper configured to attach or detach the drum cap and the coupler module to or from the chemical drum.

The present invention is an automated liquid dispenser comprising novel mechanisms for removing a single container from a nested stack of containers, closing the bottom of the container, decapping the container, filling the container, capping the container, and dispensing the filled container to a user.

A universal container capper/decapper includes a capper/decapper assembly, and an axial actuator. The capper/decapper assembly comprises a capper/decapper housing, and at least one gripper arm. The capper/decapper housing has an axis of rotation. Each gripper arm has a driven end, a gripper end, and a knee portion intermediate the driven end and the gripper end. Each gripper arm is pivotally coupled to the housing proximate the knee portion. The axial actuator is coupled to each driven end and is configured to drive each gripper end in a radial direction relative to the axis of rotation by rotating each gripper arm about the respective knee portion relative to the housing.

Systems and methods for removing a cap or lid from a container are disclosed. The systems include a decapper for removing a cap from a body of a container. The decapper includes a base configured to rest on a support surface and a prime mover supported by the base. A cap remover is supported by the base and is rotatable relative to the base about an axis of rotation. The cap remover is arranged to engage the cap of the container. The prime mover is operatively coupled to the cap remover to rotate the cap remover about the axis of rotation to remove the cap from the body of the container when the cap is engaged with the cap remover. The cap remover is arranged relative to the base such that the axis of rotation is oriented generally horizontally when the base rests on the support surface.
