Abstract

PURPOSE:To keep the load being applied on a lowermost lamination piece at a specified value all the time, to improve the working efficiency and to prevent deterioration of electric characteristics by temporarily locking a lamination piece located in an upper position until the number of lamination pieces located below a protrusion on the one side of an inner surface is decreased. CONSTITUTION:The load of an iron core is supported by bearings 11 and 12 and a lowermost iron core at a part A is extruded along a guide groove 13 by means of an insertion claw 2. When the height of a stock is lowered, the bearing 11 is rotated, and a lowermost iron core at a part B is dropped on an iron core at the part A. A lowermost iron core at a part C is then dropped on an iron core at the part B. Namely, the load of a part of the iron cores at a part C is applied on the part B, the load of a part of the iron cores at the part B is applied on the part A. However, a stock amount of the iron cores at the parts B and A is kept at a constantly specified value. Therefore, a load applied on the lowermost iron core at the part A is kept at a constantly specified value, simultaneously with stabilization of an iron core insertion given pressure, damage exerted on an iron core surface is also decreased, electric characteristics are prevented from deterioration, and a product freed from unevenness in electric characteristics is produced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vertical feed gutter for laminated pieces used in iron core insertion machines, address printing machines, name bulletin printing machines, and the like.

[Conventional technology]

Currently, an iron core insertion machine as shown in FIG. 1 is used to insert the iron core into the transformer coil.

This iron core insertion machine is a manual type (there is also an electric type), and when the handle l is rotated clockwise, the iron core insertion claws 2.3 move left and right, and the transformer coil 4 is moved left and right. Feed out each iron core one by one from the vertical supply Sakaki 5゜5" for the ■-type iron core and the vertical supply !6.6" for the E-type iron core, which are arranged in .

The greater the amount of iron core that can be stored in each iron core supply gutter, the fewer times the iron cores are supplied, which increases the efficiency of the work.

However, when the stock amount is increased, the core's own weight presses down on the lower end of the core, making it difficult to operate the handle and making the work difficult. This will cause damage and the electrical characteristics will deteriorate as shown in Table 1.

Table 1: On the other hand, if the amount is decreased, there is a problem in that the iron core floats and gets caught inside, making it impossible to stably insert the iron core.

Therefore, in order to increase the stock amount, conventionally, as shown in FIG.
, 9' are provided and operated intermittently.

However, although this method can prevent an excessive load from being applied, it is not possible to always insert a constant load.

[Problems to be Solved by the Invention] The present invention provides a product in which the load applied to the bottom of the laminate is always constant regardless of the amount of stock, improving work efficiency and preventing deterioration of electrical characteristics. This is the issue.

[Means to solve the problem]

The present invention solves the above problems by the following very simple means.

That is, the present invention solves the above problem by providing a protrusion on one example of the inner surface and temporarily fixing the laminated pieces located above the protrusion until the number of laminated pieces below the protrusion is reduced.

[Effect]

The provision of the protrusions narrows the passage accordingly, so the laminated pieces above the protrusions are temporarily fixed in an inclined position.
As the number of lower laminate pieces decreases, they fall onto the lower laminate pieces one after another. Therefore, the load applied to the lowest laminated piece is kept substantially constant.

[Embodiment] FIG. 3 shows an example of an embodiment in which the present invention is applied to a vertical supply gutter of an iron core insertion machine, in which a bearing is used as a protrusion in the vertical feed gutter 10. That is, in this case,
Two bearings 11 and 12 with a portion protruding inward are provided in a staggered manner.

According to this structure, the load on the iron core is 11°12°
When the lowest iron core in section A is pushed out along the guide groove 13 by the insertion claw 2 and the stock height decreases, the hair ring 11 rotates and automatically pushes out the lowest iron core in section B. The core falls onto the iron core in part A, and then the lowest iron core in part 0 falls onto the iron core in part B.

In other words, part of the load of the iron core in part 0 is applied to part B, and part of the load of the iron core in part B is applied to the iron core in part A, but the stock of the iron cores in parts B and A is Since the amount always remains constant, A
The load applied to the iron core at the bottom of the section is always kept constant, and the pressure required to insert the iron core is stabilized. At the same time, damage to the iron core surface is reduced, preventing deterioration of the electrical characteristics, and improving the electrical characteristics. This means that a product with no variation can be obtained.

[Different Embodiments] It is preferable that the protrusion amount or position of the protrusion can be varied depending on the thickness and weight of the laminate piece, so that the degree of fall can be adjusted.

Fig. 4 shows an embodiment in which a protrusion 14.15 with a variable protrusion amount is provided, and the protrusion amount of the protrusion 14.15 can be changed by rotating a knob 16.17. . Note that 18 is a fixed Nando.

In the case shown in Fig. 4, the degree of fall of the laminated piece can be adjusted by adjusting the amount of protrusion of the projections 14 and 15. Although not shown here, the position of the projections can be adjusted. The structure may be such that it can be adjusted up and down.

Although the above explanation has been made in relation to an iron core insertion machine, the present invention can be applied not only to an iron core insertion machine but also to vertical supply troughs used in address printing machines, name plate printing machines, etc. Of course there is.

〔Effect of the invention〕

The load applied to the lowest laminated piece can be kept constant at all times, which has the effect of preventing damage to the surface of the laminated piece and clogging of the supply of the laminated piece.
