Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a non-ferrous metal can conveying device. More specifically, the present invention relates to an alignment conveyance device for changing the conveyance form from multi-row conveyance to single-row conveyance when non-ferrous metal cans are conveyed in series.

0 Prior Art and its Problems Belt type conveyance, Cheno rope type conveyance, and air jet type conveyance are known as nonferrous metal can alignment and conveyance devices.

Belt-type conveyance has disadvantages such as being unable to convey at high speed, making it impossible to improve performance, and not being able to change the speed locally.

Cheno-lobe type conveyance is a continuous arrangement and cannot be divided (if divided, there will be a step at the dividing point, making the structure complicated), so the speed cannot be changed locally, high-speed conveyance is not possible, and the drive part is a source of dust. There are drawbacks.

In the air jet type conveyance, as shown in Fig. 12, powerful air is ejected from holes 2 provided in the bottom surface 1 of the conveyance path, and as shown in Fig. 11, the air jets are aligned from the multi-row conveyance path A on the cleaning line side. The non-ferrous metal cans P are transported to the single-row transport path C via the transport path B, and are supplied in a single row to the filling line. In FIGS. 11 and 12, 4 is a guide.

In the above air jet type conveyance, it is possible to partially change the speed depending on the diameter of the hole or pressure, etc., but in order to increase the conveyance capacity for high-speed conveyance, it is necessary to increase the air pressure, which may scatter dust etc. Therefore, there are disadvantages such as dirt getting into the can and hygienic problems, and if it is after the washing line, the washing water is destroyed, causing the same hygienic problems as mentioned above.

0 Means for Solving the above-mentioned Problems The present invention aims to eliminate the above-mentioned drawbacks of the prior art. By arranging a plurality of linear induction motor coils and changing the transport speed of the nonferrous metal cans by each linear induction motor, the nonferrous metal cans are transported from multi-row transport to single-row transport without clogging.

○Example The following description will be made based on the embodiments shown in the drawings.

In the first embodiment shown in FIG. 1, linear induction motors of the same width are provided in the single-row conveyance path C and the aligned conveyance path B, and a large number of linear induction coils are arranged below the bottom surface 1 of the conveyance path. A linear induction motor is constructed between LIM 2. LIM3.
LIM4 is the induction motor for each section LIM2゜LIM3. Regarding the LIM 4, the excitation current to the linear induction coil 5 is changed to make the conveying speed (conveying force) for the non-ferrous metal can P freely selectable. Thus, in the alignment conveyance path B, the linear induction motor LIM2. LIM3. Part of LIM4 is deployed and guide 4B.

4B, there is a non-conveyance drive surface 6 (see FIGS. 1 and 3).

In the multi-row conveyance path A, the linear induction coil 5 is arranged between the guides 4A, and the linear induction motor (LIMI') is operated during the break in the multi-row conveyance path A (see FIG. 4).

The guides 4B, 4B of the aligned conveyance path B are connected to the guides 4A, 4A of the multi-row conveyance path A at the starting end, and are connected to the guides 4C, 4C of the single-row conveyance path B at the end, so that the guides 4B, 4B of the aligned conveyance path B are connected to the guides 4A, 4A of the multi-row conveyance path A. We are gradually reducing the width between them.

In the second embodiment shown in FIG. 5, the linear induction motor installed in the alignment conveyance path B is replaced with the linear induction motor L of the single-row conveyance path C, similar to the first embodiment described above.
The width is approximately the same as that of IM4, but depending on the change in the width of the alignment conveyance path B (that is, the change in the conveyance path area), 3 rows, 2 rows, 1 row
three rows of linear induction motors LIM2-1°LIM2-2. (See Figure 6C for placement of LIM2-3)
, next, two rows of linear induction motors LIM3-1. (see Figure 6), extend the linear induction motor LIM4 of the single-row conveyance path C to the single-row conveyance path C side.
The non-conveying drive surfaces 6 are arranged in rows on both sides (see FIG. 6C).

In the second embodiment, even if the supply of cans is interrupted and intermittent, the cans can be conveyed, and the force toward the center of the can can be freely controlled by the guide resistance and the conveying path reduction slope angle.

In the third embodiment shown in FIG. 7, a plurality of linear induction motors LIM2. LIM3°L IM4 are arranged to cause the linear induction motor to act on most of the area of the bottom surface 1 of the conveyance path.

In the fourth embodiment shown in FIG. 8, an air jet type conveyance mechanism similar to that of the prior art is provided on the non-conveyance driving surface 7 in the first embodiment. Since this is only for the purpose of bringing the air to the center, the pressure is sufficient even if it is weaker than in the conventional device, so that the scattering of dust, water, etc. by the air is prevented.

In the figure, 7 is a frame that supports a linear induction motor and the like.

In the alignment conveyance path in which the present invention is implemented, the alignment conveyance path B
Multiple linear induction motors LIM arranged in
2. LIM3. The conveying speed (or conveying force) of the linear induction motor can be controlled by adjusting the LIM4 according to conditions such as the area ratio of the conveying surface (the conveying speed is changed by the inverse ratio), the guide resistance, and the force that gathers in the center of the conveyed nonferrous metal can due to the area reduction. The non-ferrous metal cans P are sequentially pushed into the starting end of the alignment conveyance path B in multiple rows as shown in Fig. As it travels along the aligned conveyance path B, the number of rows is reduced while disorganizing the rows, and it is pulled out to the single-row conveyance path C. At the terminal end, it forms a train of vehicles and is supplied to the single-row conveyance path C in a single-row state.

Referring to FIG. 10, the conveyance speed vM of the multi-row conveyance path A, the conveyance speed of the aligned conveyance path B (average speed of the plurality of linear induction motors LIM2.LIM3.LIM4),

In the embodiment, since the multi-row conveyance path A and the single-row conveyance path C are also driven by linear induction motors, the effects of the present invention can be further enhanced. The object of the present invention can also be achieved even if

O Effects of the invention.

The effects of the present invention are listed below.

(1) It is easy to adjust the feed speed, and high-speed conveyance is possible, increasing conveyance efficiency.

(2) The transport path is divided into multiple sections and the transport speed is varied, but unlike belt-type transport, there are joints and there are no uneven parts, and there is no back pressure, so cans become clogged. Cans can always be sent to the single-row conveyance path in an orderly manner without causing any problems.

(3) Dust is not generated on the alignment conveyance path, the cans are kept clean, and the working environment can be improved with low noise.

(4) The alignment conveyance path requires less maintenance, has a long life, and can reduce management costs.
