JPH02300015A - Attraction head for vertically work setting device - Google Patents

Abstract

PURPOSE:To prevent powder and the like layed on the surface of a work from scattering in a device for vertically setting a plate-like work with respect to a vessel by forming a groove for making air escape between works on the work attraction face of attraction pad of an attraction head. CONSTITUTION:Attraction holes 10b are, respectively, bored on the work attraction faces 10a of attraction pads 10A in correspondence with plate-like works W aligned tightly vertically, and air escaping grooves 10c penetrating vertically and laterally are formed integratedly with specified depth at the portion between the works W of the work attraction faces 10a. Under such structure, air between the works W in the vertical direction is pushed out when they are set into a vessel. It is thus possible to prevent powder and the like layed onto the overlapping face of work form scattering.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a suction head for a vertical workpiece packing machine.

(Prior Art) Conventionally, as shown in FIG. 8, flat workpieces (e.g. ceramics) W are placed close together vertically and horizontally on a conveyor or the like.
A vertical packing machine has been put into practical use in which workpieces W are simultaneously adsorbed by suction pads 2 of a suction head l and stacked in multiple stages (for example, four stages) in containers (boxes) 3 located at different positions.

The workpieces W stacked in multiple stages in the container 3 are transported together with the container 3 to a firing furnace to undergo heat treatment.

By the way, in order to prevent the workpieces W from bending or seizing during the firing process, when stacking the workpieces W in multiple stages in the container 3,
It is necessary to sprinkle ceramic powder between the workpieces W.

(Problem to be Solved by the Invention) However, since the workpiece suction surface 4 of the suction pad 2 of the conventional suction head 1 is flat as shown in FIG. As shown in the figure, the air between the previous workpieces W (indicated by cross hatching) and the air between the subsequent workpieces are pushed out so as to blow between the stacked surfaces of each workpiece W (see arrows).
There was a problem in that the ceramic powder sprinkled on the stacked surface of the previous workpiece W was scattered, causing bending and seizure during the firing process, and resulting in a high product defect rate.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a suction head for a vertical workpiece packing machine that can effectively prevent scattering of powder and the like.

(Means for Solving the Problems) For this reason, the present invention simultaneously suctions flat workpieces arranged in close contact vertically and horizontally with a suction pad of a suction head.
In vertical packing machines that stack workpieces in multiple stages in containers,
It is characterized in that air escape between the works is formed on the work suction surface of the suction pad of the suction head.

(Operations and Effects of the Invention) Does the present invention provide suction with a suction head? Air relief grooves are formed on the workpiece suction surface of the CRADO, so when stacking workpieces, the air between each workpiece is pushed out from the relief groove on the workpiece suction surface, so that the previous workpiece is not stacked. Powdery dust etc. scattered on the surface will not scatter.

In addition, since the suction pads corresponding to the workpieces are not individually attached to the suction head at intervals, only grooves are formed in one suction pad, so the suction surface corresponding to each workpiece is - Maintains the accuracy and prevents workpiece suction errors from occurring.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 7, the vertical packing machine for the workpieces W is provided with a suction head 11 with suction pads 10 (A-D) attached at the bottom, and a guide rod +
? , + 2 are installed and the guide rod 12.12
is vertically movably supported by guide sleeves 14 and 14 of a bracket 13 fixed to the conveyor.

There is a spring in the guide rod 12.12 above! 5.15
is compressed and the suction head 11 is urged downward by the spring +5.15, and the guide rod 12.
12 stoppers 12a, 12a are guide sleeves +
It is fixed against the upper end surface of 4.14 and is positioned in the correct position.

As shown in FIG. 1, the work suction surface 10a of the suction pad 10(A) has suction holes 10b, .
is dawning.

The space between the workpieces W on the workpiece suction surface 10a is as follows:
Air escape grooves 10c are integrally formed to penetrate vertically and horizontally to a predetermined depth.

The air escape groove 10c is connected to the suction pad 10 (A) shown in FIG.
), or as shown in the suction pad 10(B) in Fig. 2, the air escape groove 10c is integrally formed by leaving a round surface with a diameter slightly smaller than the outer diameter of the circular workpiece W. It may be formed as follows.

With the above configuration, as shown in FIG.
When stacking the workpieces W” after adsorption at (A, B),
The air between each workpiece w' and w'' is
Since the air is pushed out from the air escape groove 10c of a, it is possible to prevent the scattering of powder, etc., which was scattered on the overlapping surface of the previous workpiece W°.

As a result, there will be no bending or sticking during the firing process, and the product defect rate will be reduced.

Further, since the grooves 13 are simply formed integrally with the suction pads l0 (A, B), the coplanarity of the suction surfaces 10a corresponding to each workpiece can be maintained.

As a result, mistakes in suctioning the workpiece W are also eliminated.

In the embodiments shown in FIGS. 1 to 3, the suction pads 10 (A, B) are smaller than the container 16, and the container 16 and the suction pad 10 are
(A, B), but as shown in FIGS. 4 to 6, the suction pad 1
0 (C, D) is large, and the container 16 and suction pad 10 (C
, D) is small, (t >t'
), escape grooves 10c formed in the suction pads 10 (C, D)
The depth should be increased to ensure an air escape route.
