Abstract

Gripper-table arrangement with simultaneously lifting table, when the gripper arms close characterized in that the material to be gripped is detected scaling, d. H. the ratio of width and height of the horizontally detected object remains largely constant, so that objects of different sizes can be detected in the same way as they are on the table raised vertically.

Description

Object of the invention

The aim of the invention is to be able to peel soft nuts with a single hand on a gripper-table unit, purely mechanically without external energy sources. Disabled people with only one healthy hand do not need to bite into the shell, especially citrus fruits when opening. Even people with only two healthy hands benefit from it, the hands are not splashed when opening. Presently known solutions lack the flexibility to give sufficient peel sizes and crops a sufficient hold to peel.

Scaling gripper table unit

There are many people with a physical disability, such as For example, with a missing arm that can not peel a peel fruit like a tangerine or similar fruit well. That's why I've thought of developing a device that can hold the peel fruit and peel it with a peeler or a knife. A height-adjustable piston with a horizontal round plate attachment, which can be adjusted by different bulge sizes of the size and type of fruit, a fruit fixation is possible. The fruit to be peeled is then placed on the plate. The piston under the plate is pushed up by an additional compression spring. By pressing the operating lever, which is attached by a rope with the gripper arm and by another rope at the end of the cylinder, the piston is pushed by the spring further upwards and thus adapted to the fruit size. The device also has four gripping arms, which fix the fruit by a rope over the contraction. The gripping arms are attached to metal plates by joints. Characterized in that the tension springs which are attached to the gripping arms on the outside are under constant train, a balance of the gripping arms is shown with the rope. In addition, the pull rope is guided around a roller which stabilizes the rope from the foot pedal via the gripping arms up to the cylinder. So now the fruit can be peeled with a knife or peeler. This device gives many people great support and relief in their everyday lives so that they can help themselves without the help of others.

Fields of application of the invention

Due to the great flexibility in terms of size, roundness and elasticity of ball-like bodies, fixations of soft as well as harder bodies by the gripper-table unit are possible. These can then be well processed by a good accessibility (possibly still improved by means of a turntable). By re-fixing the still unprocessed areas can be edited / peeled. With this system, but also bodies are fixed, which does not necessarily have to have a sphere-like geometry. Thus, this invention is also applicable to completely different body shapes that are to be processed. Through attachments on the grippers such as suction cups, upholstery, grooves, spines, various materials such as glasses, ceramics, plastic, metal, wood, with non-liquid content can be opened by the screw of the tube fixed by the device and the tube by hand is turned.

Explanation of the essence of the invention

The invention has for its object to provide a gripper mechanism for a Manipuliereinrichtungen via an operating pedal, which allows a centric, non-slip clamping of bodies. According to the invention this object is achieved by four profiled at the contact points gripper, which move with the same angular velocity to the body to be fixed, by pressing a foot pedal. At the same time, the body to be fixed is moved upwards by a piston with interchangeable inner contours adapted to the body. Due to the constant, the situation adapted operation of the foot pedal, the force required to fix the body is applied. The combination of the movement of the tongs and the table from different directions in adapted size, d. H. scaling to the workpiece, coupled with premature and frictional touches, make up the essence of the invention.

Function Description:

By pressing the control pedal ( 4 ) with the foot down, the return spring ( 5 ) and the traction cable moves, guided by pulleys ( 7 ), downward. This moves the gripper ( 3 ), guided by the joints ( 1 ), in the direction of the piston ( 10 ). The return springs ( 8th ) of the gripper tensioned. One of the four grippers ( 3 ) is over another rope ( 11 ), guided over a deflection roller, with the piston ( 10 ) and relaxes by the movement of the piston pressure spring ( 9 ). The piston thus moves a little way up and clamped by the spring force the body to be machined together with the grippers. After releasing the control pedal, the system is activated by the springs ( 8th and 5 ) returned.
