Description

[Detailed description of the invention] "Industrial application field" TECHNICAL FIELD The present invention relates to a thumbtack handling device, and more particularly, to a thumbtack handling device.

Thumbtacks can be pulled out smoothly, the thumbtacks that have been pulled out can be stored in stock, and when needed, the stocked thumbtacks can be drawn out with a single touch and inserted at the required location. Related to thumbtack processing equipment.

``Prior art'' Thumbtacks that are deeply inserted into walls, etc. are difficult to remove, and even if you try to pull them out by picking the head of the tack with your fingernails, it is not easy, and in the end, you have to use a screwdriver etc. Must be removed.

However, if dryomer or the like is used in this way, it will not damage the wall surface, etc., and if it becomes deformed, it will seriously spoil the aesthetic appearance of the wall surface, etc. In addition, in the case of posters and the like, since there are many copies, it would be time-consuming and labor-intensive to remove them one by one using dryomer or the like.

Unfortunately, the thumbtack often falls to the floor the moment it is pulled out using a dry knife, and I have often experienced injuries caused by inserting the missing thumbtack into my foot.

Also, when inserting thumbtacks, it is difficult to insert them if you have many thumbtacks in your dominant hand.

It is common practice to hold a few thumbtacks in your other hand and insert them into the other hand, but this takes a lot of time. I couldn't hold it down.

The work is also easy.

"Problems to be Solved by the Invention" The present invention has been made in view of the above-mentioned points, and it is possible to smoothly pull out thumbtacks and to reliably stock the pulled out thumbtacks in the case. Moreover, when you do not want to use a stocked thumbtack, you can unroll it with one touch and insert it into the required place, and all these extraction and insertion operations can be done with one hand. It is an object of the present invention to provide a thumbtack processing device that can perform the following operations.

In addition, 22 in the figure indicates a thumbtack.

"For work" Next, the operation of the present invention will be explained.

When removing the thumbtack from a wall, etc., use the thumbtack puller piece 13 to lift the head of the thumbtack and insert the shaft into the thumbtack shaft guide groove 13a', and as you lower the case 1, the thumbtack will gradually come out. pulled out.

The pulled out thumbtack falls into the thumbtack head holding rail 11 of the case 1 through the thumbtack falling groove 13c.

Further, the depressed thumbtacks are stored in a line one after another in the thumbtack head holding rail 11. Further, the head of the thumbtack that has fallen into the rail 11 for holding down the head of the thumbtack comes into contact with the transfer route 8 on the driven pulley 3 side.

In this state, if there is no thumbtack on the transfer belt 8 further ahead, insert your finger from above the window of the case 1 and rotate the driven pulley 3 to perform fast forwarding. As a result, the thumbtack can be moved to the hook portion 20b' of the thumbtack operation control board 20.
sent to.

In addition, when one thumbtack is already full on the thumbtack head holding rail 8 and you want to reuse the thumbtack, press down on the push button 14 to -
The individual thumbtacks fall onto the disc-shaped permanent magnet 12 fixed to the thumbtack pressing base 1a and are set in the insertable portion.

That is, when the push button 14 is pushed down, the push operation plate 1
9 is bent into a U-shape (the rounded base 19' is pushed, and at this time, the outer surface of the U-shaped part is shifted toward the front side of the case 1 because the inclined plate 18 is in contact with it). Along with this, the suppressing portion 19a at the tip of the push-out operation plate 19 presses the first control plate 20a of the thumbtack feeding control plate 20. As a result, the tip on the lower side of the first control plate 20a is lifted up. The thumbtack 22 comes off from the 9° hook part 20a' and slides down the upper slope of the pushpin pressing base 1a due to its own weight. and is ready for insertion.

``!! Just in case, the first control plate 20a is pushed further forward, and the pressing part 19a of the push-out operation plate 19 is activated to the first control [2
When the first control plate 20a enters into the U-shaped bent portion 20a'' of 0a, it returns to its original state and becomes able to accept the next thumbtack. The pressing part 19b of the operation plate 19 is the second control plate 20b.
1. At the same time, when the push button 14 is pressed down, the drive pulley 2 also rotates via the rotary drive arm 17. Therefore, the thumbtack comes off from the hook 20b' provided at the raised tip of the second control plate 20b and moves forward, and is stopped by the hook 20a' of the first control plate 20a. By repeating this sweeping process, the stocked thumbtacks 1 are sequentially moved to -1, usable. Toka, aki.

It is something.

Next, a second embodiment of the present invention shown in FIGS. W16 to W18 will be described.

FIG. 16 is a partial sectional view of the front end of the case, FIG. 17 is a side view of the push-out operation plate, and FIG. 18 is a perspective view of the thumbtack feed-out control plate.

What is the difference between this embodiment and the first embodiment?

Push out the operation plate 19 with its base 19' shaped like a t'
1, the end is pivotally connected to the back of the push button shrine, and a rotary drive aperture is provided in the middle of the base of the push-out operation plate 19.
- fix the thumbtack 17, and the first thumbtack feed control plate 20 on the other hand.
The U-shaped bent portion of the control plate 20a is replaced with a cutout portion 20rartr.

It should be noted that other points are similar to those of the embodiment of Zheng 1, so the same reference numerals are given to the other members, and detailed explanation thereof will be omitted.

However, in the case of this embodiment, when the push button 14 is pressed, the push operation plate 19 is shifted to the front side of the case 1, and accordingly, the drive pulley 2 is rotated by the rotation drive arm 17, and the push operation plate 19 is rotated by the rotation drive arm 17. A pressing portion 19a at the tip of the plate 19 presses the first control plate 20a of the thumbtack feed-out control plate 2° to feed out one thumbtack. When the push-out operation plate 19 is further shifted forward, the pressing part 19a at the tip thereof becomes the notch part 2Q.
The first control plate 20 returns to its original state. When the push-out operation plate 19 is further shifted forward, its pressing portion 19b comes into contact with the second control plate 20b and presses it to send one thumbtack to the first control plate 20a.

"Effects of the Invention" Since the present invention has the above-mentioned configuration 1, it is possible to very smoothly pull out thumbtacks inserted into a wall surface, etc., and it is also possible to store the pulled out thumbtacks as they are. Furthermore, the thumbtacks that are kept in stock can be drawn out and used with a single touch when needed. Since you can pull out and insert thumbtacks with just one hand, your other hand is free and you can work more smoothly.

Furthermore, since the structure is not so complicated, it can be manufactured at low cost, and has many advantages in practical use.
