Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention belongs to the field of handling thin plate-like materials, and relates to a suction tool for suction-treating the material using vacuum pressure.

(Prior Art) In the case of a suction tool that has been used in the past, if the material to be hung is easily deformed, it may be necessary to adhere a receiving material with a slight gap to the surface inside the pad. Although it has been proposed, when the material to be suspended has holes or large cracks and is difficult to be deformed, the suction force is reduced and the material falls off.

(Problem to be Solved by the Invention) The present invention provides an adsorbing tool capable of reliably suspending a material that is difficult to deform even if it has holes or cracks.

(Means for Solving the Problems) The suction tool of the present invention is a suction tool main body having a receiving portion and a suction port at the upper portion of a vacuum chamber, and the suction surface of the main body has a large number of small holes penetrating the suction member. The receiver is integrally covered, the surface of the adsorbent receiver is covered with an adsorbent composed of a porous material, and the surface of the adsorbent is provided with a required compression margin from the surface of the presser foot that locks the periphery of the adsorbent. It is arranged and projected.

(Function) Adhesion surface of the suction tool body to the material (Since there is a compression margin between the surfaces of the presser foot, if the suction tool is crimped to the material when suspending the material, it will be adsorbed to the holes and cracks existing on the material suction surface. The surface of the material will be embedded.

(Embodiment) The present invention will be described with reference to an embodiment. As shown in FIG. 1, in a suction tool body 1 having an attachment receiving portion and a suction port portion in an upper portion of a vacuum chamber, a suction surface (whether circular or rectangular) of the body 1 is used. Adsorbent receiver 3 having a large number of small holes 2 formed through it is integrally covered, and a downwardly convex adsorbent 4 made of a porous material (such as sponge rubber) is provided on the surface of the adsorbent receiver 3. The adsorbent 4 is covered, and the periphery of the adsorbent 4 is pressed by the presser foot 5 to be detachably fixed to the adsorber main body 1. At this time, the surface of the adsorbent 4 and the presser foot 5 are attached.
A required compression margin s is arranged between the surfaces of the.

As shown in FIG. 2, the suction tool a thus configured is pressed against the material 6 before suction when suspending a material 6 which is difficult to deform, for example, a single plate or the like. If there is a deficient portion 7 such as a hole, the adsorbent 4 is inserted into the deficient portion 7 to minimize the suction port portion D for air to suppress a decrease in the degree of vacuum and hold the hanging force. As shown in FIG. 3, when there is no compression pressure between the surface of the suction tool and the surface of the deformation suppressing material 8 stored in the suction tool body 1, there is a gap 9 in the suspended material 6. If there is, the degree of vacuum is lowered and it becomes impossible to suspend.

In this way, the adsorbent 4 is provided with a compression allowance, and the material 6 is suspended.
It has a feature that the hanging force is not remarkably reduced even if there is the defective portion 7. Further, since the adsorbent 4 is detachably locked by the presser foot 5, the adsorbent 4 is appropriately selected by the material 6 to be suspended and easily attached and detached.

(Effects of the Invention) As described above, according to the suction tool a of the present invention, even when suspending a material that is difficult to deform, the suction tool a has a feature that the reduction of the suspension force due to the loss of the material can be suppressed as much as possible. There is an effect that the adsorbent can be easily attached and detached according to the material to be suspended.
