Description

[Detailed description of the invention] This invention uses the restoring force of a spring or gas pressure such as air pressure as a power source to reciprocate the driver member in the vertical direction, and temporarily fixes soft interior boards etc. until the adhesive dries. The present invention relates to a temporary seal driving machine for driving temporary seals and the like equipped with washers, and more particularly to a device that prevents the temporary seal from collapsing when driving the temporary seal into a material to be driven.

Generally, when attaching an interior board such as plywood to a wall in a room, adhesive is used between the interior board and the wall. During this time, the interior board is temporarily attached to the wall using a needle-shaped temporary seal, and the temporary seal is removed once the adhesive has hardened.

A soft and elastic washer is fitted into the shank of the temporary seal adjacent to the head of the temporary seal.

This washer is used to prevent damage to the soft interior board.

However, in a temporary seal driving machine that can use a connecting plate needle that connects a large number of temporary seals using a long washer with a large number of separation notches formed at regular intervals,
When separating the most advanced temporary seal of the connecting plate needle prepared in advance in the temporary sealing guide from the subsequent connecting plate needle, the striking surface of the driver member hits the entire upper surface of the washer at the same time, and the washer is cut. Due to resistance and elasticity, a moment whose arm length is the distance from the washer separation site to the nail head acts on the leading edge of the temporary seal, so that the needle foot of the leading edge of the temporary seal is connected to the subsequent connecting plate needle. This collapsed posture is not corrected within the short stroke of the driver member, and the needle foot of the temporary seal hits the interior board and is about to be driven in. Even if the nail was bent, the edge of the lower end surface of the washer would damage the soft surface of the interior board.

This scratch on the surface of the interior board is fatal for temporary sealing work, which is performed on the premise that the temporary seal will be removed after the adhesive has dried.

The purpose of this invention is to remove the temporary seal at the most extreme position when separating the washer fitted in the temporary seal at the most extreme position from the other part of the long washer in a temporary seal driving machine that uses a connecting plate needle. To provide a temporary seal driving posture control device that does not cause posture collapse and allows the temporary seal to be normally driven into a material to be driven without being bent.
