Problems solved by technology

[0007] However, the gasket supply device making full use of the back sheet constituted by the above-mentioned releasable sheet has a problem that, when a gasket of a large thickness is kept and a gasket of a small thickness is placed beside it, the gasket is subjected to external force during its shipment or transportation. Moving or shifting on the backsheet, or often detaching from the backsheet, even when the device is in the bag, gaskets detached from the backsheet stick to each other inside the bag due to their respective adhesive layers, resulting in random aggregation state, which eventually leads to the fact that the gasket cannot be conveniently used

experiment example 1

[0058] The experiment was carried out with 10 gasket supply devices in common: the gasket supply devices obtained in the above manner were placed on a horizontal surface, and were manually reciprocated laterally at a distance of 30 cm from the horizontal surface at an acceleration of about 0.5G. As a result, it was found that the number of gaskets coming out of the respective receiving recesses was zero in all the gasket supply devices.

[0059] On the other hand, the same number of the above gaskets were adhered and held in the same arrangement state on the surface of a polyethylene terephthalate sheet having a thickness of 38 μm, and the same releasability-imparting treatment was applied to the surface, except that No receiving recess is formed, thereby forming a contrast gasket supply. Ten such gasket supply devices were reciprocated in the same manner as above. The result was that an average of 8 washers were found to have moved in each installation, with a maximum distan...

experiment example 2

[0061] The washer supply device as described above was manually circled in the air once per second, and this experiment was performed on a total of 10 washer supply devices. It was found that the number of washers coming out of the respective receiving recesses was zero.

Abstract

Provided is a washer holder comprising a processed sheet in which a plurality of washer-receiving depressions each having an inner diameter fitted to an outer diameter of a washer to be held are arranged and formed, wherein the washer is received in the washer-receiving depression, and one surface of the washer is releasably held on the bottom surface of the washer-receiving depression through an adhesive. A small-diameter depressed portion is preferably formed in a central region of the bottom surface of the washer-receiving depression. The bottom surface of each of the washer-receiving depressions preferably has releasability. The washer supply device comprising the washer holder described above and washers received in the respective washer-receiving depressions and caused to adhere and held by an adhesive layer on the bottom surfaces of the washer-receiving depressions.

Description

technical field [0001] The present invention relates to a washer holder and a washer supply device. Background technique [0002] A washer is a mechanical element, usually in the form of a circular disc, and is primarily used to lock a bolt or screw into a locked state, and is also effective as an adjustment pad for example for height adjustment or to protect a base plate when tightening metal screws Protection from damage. In addition to metal washers, washers made of synthetic resin are also widely used as washers. [0003] Temporary adjustments are often urgently needed, for example during assembly operations of certain industrial products such as automobiles. In this case, it is necessary to select a gasket considered suitable among many kinds (for example, 200 kinds) of gaskets having different thicknesses and sizes, and set it in a so-called temporarily fixed state. The rationale for this is that it is often necessary to perform the actual screwing in a step in anot...
