Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is a seal that uses a U-shaped needle to join overlapping parts of cardboard, etc. Regarding the shutter mechanism, more specifically, the structure of the shutter that pushes down the needle by operating the handle. .

0002

[Conventional technology]

Insert both legs of the U-shaped needle into the cardboard, and insert the legs into the back of the cardboard. The sealing machine used for bonding by folding in a plane is shown in Figs. 3 to 5. Attach the head 2 to the tip of the holder 1 that stores the continuous needle A', which has many needles A connected to it. This head 2 has a handle 3 and a shaft that descends when the handle 3 is pressed down. shutter 4 and a pair of arms that rotate close to the bottom of the shutter 4 when the handle 3 is pressed down. and push the needle A toward the head 2 on the rear end side of the holder 1. When the handle 3 is pushed down, the holder 1 is The most advanced needle that comes into contact with the needle receiving plate 7 attached to the tip of the needle is pressed down by the shutter 4. At the same time that both legs B of needle A penetrate the cardboard, both anvils 5, 5 Penetrate the cardboard to receive the tip of the leg B, and bend the leg B on the back side of the cardboard. As a result, the needle A firmly seals the overlapping portion of the cardboard.

0003 The shutter 4 is housed in the head 2 so as to be able to move up and down, and its upper end is connected to the middle of the handle 3 which is pivoted to the top of the head 2 so that it can swing up and down. It is connected via a handle 8 and a shaft 9, and can be moved up and down by the positive movement of the handle 3. As shown in FIG. 5, the pair of anvils 5, 5 have their upper ends pivoted on both sides of the lower part of the head 2. , both sides of the upper part are connected to the upper part of the shutter 4 by links 10, 10 and shafts 11, 11. , so that when the shutter 4 moves up and down, both anvils 5, 5 rotate around the upper end pivot point. It has become.

0004 The conventional shutter 4 has a thin shutter body as shown in FIGS. 5 and 6. 12 is provided with a thick wall portion 13 that protrudes toward the front side, and at the center of the top of this thick wall portion 13 A fitting recess 14 is formed in the link 8, and a shaft 9 coupled to the link 8 is supported on both sides thereof. Handle connecting parts 15, 15 are formed, and the thick part 13 is opened on the lower surface and both sides. A slit 16 is provided on both sides of the top of the area where the slit 16 is provided. Supports the connecting shafts 11, 11 of the anvil connecting links 10, 10 inserted into the hole 16. The shutter 4 has a structure in which holes 17, 17 are provided to hold the thick part 1. Using a metal plate with a thickness corresponding to 3, the thin shutter body 12 is shaped by cutting. has been completed.

[0005]

[Problem that the idea aims to solve]

By the way, since the sealing machine is used manually, it needs to be lightweight in terms of workability and mobility. However, conventional shutters are formed by cutting out thick plates. This makes it difficult to reduce the weight of the sealing machine.

[0006] In addition, since slits must be created while cutting from a thick plate, machining requires manual labor. There are problems in that it is time consuming, involves a lot of material loss, and is expensive.

[0007] Therefore, this idea can reduce the weight of the shutter and the manufacturing cost. Our goal is to provide a sealing machine that can

[0008]

[Means to solve the problem]

In order to solve the above problems, this idea is based on the idea that the shutter is made of a single metal plate. The shutter body and one side of this body are provided facing each other on both sides of the upper part. The handle connecting wall is connected to the upper end of the shutter body on one side of the shutter body. This structure adopts a structure in which the anvil support wall and the anvil support wall facing each other are integrally bent.

[0009]

[Effect]

The shutter body, handle connecting wall and anvil support wall are made of one metal plate. Since the shutters are bent into one piece, the shutter can be made of a thin metal plate, and the shutter can be made from a thin metal plate. In addition to reducing the weight of the shutter, there is less material loss and production costs are reduced. can.

【Example】

Embodiments of this invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings. In addition, The basic structure of the sealing machine is as shown in Figures 3 to 5. Explain using symbols.

[0011] As shown in Figures 1 and 2, the shutter 4a uses a relatively thin metal plate. , the constituent parts are integrally bent and formed by press molding.

0012 The shutter 4a is a vertically long rectangle whose lower edge is the pressing surface 21 of the needle A. A shutter body 22 and an upper wall 23 bent at right angles from the upper edge of this body 22 to the front side. The upper wall 23 is bent downward from the tip at a right angle, and is in front of the shutter body 22. Anvil support wall 24 facing the surface, bent downward from both sides of upper wall 23, The integral handle connecting walls 25, 25 facing each other are integrally bent and formed, and the upper wall 2 3 to the upper part of the shutter body 22 and the anvil support wall 24, A notch 26 into which the link 8 of the handle 3 fits is provided, and both handle connecting walls 25 , 25 are provided with a support hole 27 for the shaft 9 connected to the link 8.

[0013] Further, the anvil support wall 24 is slightly shorter than the shutter body 22, and this support wall 24 is slightly shorter than the shutter body 22. Links 10, 10 of the anvils 5, 5 are installed on both sides of the wall 24 and the upper part of the shutter body 22. Support holes 28, 28 for the connecting shafts 11, 11 are provided.

[0014] The sealing machine of this invention has the above-mentioned configuration, and as shown in FIGS. 3 and 4, Insert the continuous needle A' to be used from the rear end of the holder 1 from which the pressing means 6 has been removed. Next, insert the push tool 31 of the push means 6 into the holder 1, compress the spring 32, and press the rear end. By hooking the connector 33 to the rear end of the holder 1, the device that presses the continuous needle A' forward can be The most advanced needle comes into contact with the needle receiver plate 7, and the continuous needle A' The push-down member 34 presses the handle 3 from above, and in this state, the handle 3 is When the needle is pressed down to perform the needle driving operation, the shutter 4a pushes down the most advanced needle A.

[0015]

【effect】

As described above, according to this invention, the shutter is made from a single metal plate. Since the sealing machine is formed with a ridge, it is light in weight, and the weight of the sealing machine as a whole can be reduced.

[0016] Additionally, since the shutter is made from a single metal plate and bent, there is no material loss. Since there is less raw material and it can be formed by press molding, it is easy to process and easy to manufacture. This makes it possible to significantly reduce production costs.
