Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handling device having a gripping function in equipment such as a manipulator used for conveying materials, and particularly to a device for handling soft articles or easily breakable articles.

Conventionally, soft articles and articles that are easily damaged (hereinafter referred to as "workpieces") require special consideration from removal from processing equipment such as molding machines to transportation.

In particular, in order to avoid contact between the workpieces and to prevent damage due to unexpected collisions with other objects, the containers of the workpieces,
Various improvements have been made to transportation means. An operation that has conventionally been considered difficult when manufacturing or processing the above-mentioned workpieces is the operation of removing the workpieces from the manufacturing processing equipment. Due to the characteristics of the workpiece, there are various problems when using only normal handling equipment, and for this reason, the above work has to rely on input, and mechanization and automation are delayed, so it is necessary to save labor and mechanize including related equipment. It has a negative impact on people such as The gist of this invention is to form a claw that comes into contact with a workpiece with a plate made of an elastic material, and to grip the workpiece from the outside by using a plurality of arms that follow the shape of the workpiece by utilizing the bending and restorability of the elastic material. Glass, which is particularly susceptible to breakage,
The main point is to handle workpieces such as ceramic materials and powder molded products without damaging or rupturing them.

Examples of the present invention will be shown below with reference to the drawings.

In FIG. 1, a is a side view, b is a perspective view, and FIG. 2 is a front view of main parts. In both figures, 3 and 3a are opposing arms, and the arm 3 has a claw 1 made of an elastic material fixed to the inner surface of the U-shaped arm with an appropriate gap by a screw 2. Further, a claw 1a made of an elastic material is fixed with a screw 2 to a central arm 3a located at the center of the U-shaped arm. Note that a space Ib is provided between each claw and the arm. The arms 3 and 3a are rotatably attached to the support plate 5 via pins 4 so that the outer ends of the arms 3 and 3a protrude to one side of the support plate 5. Next, a cylinder 9 is fixed to the other side of the support plate 5. A metal fitting 8 is fixed to the piston rod 9a, and the metal fitting 8 and the arm 3,
The inner end of 3a is connected via link plate T and pin 6. The arm shall be able to freely widen or narrow the gap between its claws depending on the item to be grasped.
With the above configuration, the cylinder 9 is operated and the arms 3, 3 are
When a is closed, the claw 1 made of an elastic material is opened as shown in Fig. 3.
deforms and comes into close contact with the outer circumference of the workpiece 10, and the workpiece 1
It grasps 0.

When the workpiece 10 is transported to a predetermined position and the arms 3, 3a are released, the claw 1 made of an elastic material returns to its original state as shown in FIG. 2 due to its elasticity. Although the embodiment has shown an example in which the arms rotate, the effect is the same even if the opposing arms are moved in parallel. As explained above, by implementing the present invention, easily damaged workpieces can be grasped in a soft manner, thereby eliminating the risk of scratches, deformation, cracks, etc. occurring in the workpieces.

Further, the present invention is particularly capable of gripping long cylinders, prisms, or similar workpieces, and can be gripped freely by increasing the number of arms. The gripping force can be adjusted by changing the material and strength of the elastic material depending on the workpiece. The handling work that was conventionally done by acquisition is mechanized and automated, and it is possible to greatly save labor including related equipment, or to automate it, or even to make it unmanned.

[Brief explanation of the drawing]

1A and 1B are a front view and a perspective view showing an embodiment of the present invention, FIG. 2 is a front view of the same, and FIG. 3 is a partially enlarged front view showing the working state of the claw in FIG. 2. 1: Claw, 3, 3a: Arm, 10: Work.

Claims (1)

[Claims] 1. A handling device having opposing arms that can be opened and closed, with a U-shaped arm having an appropriate gap on one side and a central arm located at the center of the U-shaped arm on the other side, A handling device characterized in that a claw made of an elastic material is attached to the opposing surface with a gap therebetween.
