Description

[Detailed description of the invention] (a) Technical field of the invention The invention relates to a transport system that uses a linear motor to move a transport object, and in particular a transport system that allows easy rail switching at the branch point between vertical rails and horizontal rails. Regarding the mechanism.

(b) Background of the technology In recent years, various counter transaction devices have been introduced in financial institutions as part of their efforts to streamline administrative processes, and automation is progressing. A system for automatically depositing and withdrawing money by connecting them with a transport device has been put into practical use.

Furthermore, in offices in high-rise buildings and the like, a system is generally used in which objects such as documents are moved at high speed between upper and lower floors.

When carrying out three-dimensional transportation spanning upper and lower floors in this way, it is necessary to easily switch the branching point between the vertical rail and the horizontal rail.

(c) Prior Art and Problems Conventionally, methods using conveyors, elevators, air shooters, linear motors, etc. have been used to transport cash, documents, etc. to upper and lower floors.

However, although conveyors and elevators can transport vertically, they cannot automatically branch horizontally. Moreover, the conveyance speed is low.

Although the method using an air shooter enables vertical and horizontal conveyance, it has drawbacks such as imprecise positioning of the stop position and limitations on conveyance speed.

Particularly when transporting cash for deposits and withdrawals at financial institutions, etc., it is necessary to accurately stop at the teller station and storage station in order to automatically load onto the carrier and automatically deposit and withdraw cash from cash storage safes. .

As disclosed in Japanese Unexamined Patent Application Publication No. 113401/1988 filed by the present applicant, the method using a linear motor enables high-speed conveyance in the horizontal and vertical directions, and the accuracy of the stopping position in horizontal travel is also improved. Although it has the advantage of being expensive, the conventional method has the disadvantage that the transport path is not branched.

(d) Purpose of the invention The purpose of the invention is to solve the above-mentioned drawbacks, and to provide a transport mechanism that allows easy rail switching at the branching point between vertical rails and horizontal rails, high-speed transport, and high accuracy in stopping positions. is to provide.

(e) Structure of the invention The invention consists of a horizontal rail laid on the upper and lower floors of a building, a vertical rail branched from each horizontal rail and installed on a wall or column, and A transport mechanism comprising a transport path having a rail and a branch part provided at a position where the vertical rail branches, and a transport body running on the transport path with an object loaded thereon, the branch part being A linear rail of a predetermined length and a curved rail curved in the rising direction that allows the transport object to run from each of the vertical and horizontal rails, which constitute a part of the transport path, are placed on the same surface with one end part of both at intervals. The straight rail and the curved rail connected by the connecting member are connected to the conveyance path by placing the connecting member on the floor, wall surface, or column surface, and connecting the straight rail and curved rail connected by the connecting member. A position where the linear rail is connected to the straight rail when the conveying body is moved in a straight line, and a position where the curved rail is connected to the vertical rail or the horizontal rail when the traveling direction of the conveying body is changed. This is a conveyance mechanism characterized by having a configuration that allows switching and movement, and by doing so, the purpose can be achieved.

(f) Embodiment of the invention An embodiment of the invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a side view showing an embodiment of the present invention, and FIG. 2 is a plan view of FIG. 1.

As shown in FIGS. 1 and 2, vertical rails 1a, 1
b are arranged above and below the switching point 3, and the horizontal rail 2 is arranged to the right of the switching point 3.

The switching point 3 is a straight rail 4, a rail curved into a 1/4 arc (hereinafter referred to as R rail) 5,
It is composed of a connecting plate 6 that connects the straight rail 4 and the R rail 5, and a switching mechanism 7 that moves and switches the connected straight rail 4 and R rail 5.

The straight rail 4 and the R rail 5 are connected by a connecting plate 6 with one end on the same plane and spaced from side to side.

In the switching mechanism 7, a feed screw 9 is screwed into threaded plates 8 attached to the left and right sides of the connecting plate 6, and a motor M1 is connected to the feed screw 9.

Therefore, by the forward and reverse rotation of the motor M1, the switching point 3, which is a branching part, moves in the directions of arrows C and D in the figure, and is switched as shown by the broken line and the solid line.
Vertical rails 1a, 1b and straight rail 4 constitute vertical conveyance path A, and horizontal rail 2 and R
The rails 5 constitute a horizontal conveyance path B.

Further, the carrier 10 is a storage box 1 in which cash, etc. is loaded.
1 and wheels 12, and runs on transport paths A and B, and is equipped with an iron core (not shown) of a linear motor and a magnetic field generating coil, and is a primary iron core on vertical rails 1a, 1b and horizontal rail 2. A carrier 10 equipped with a secondary conductor (not shown) runs.

With this configuration, when the carrier 10 travels on the vertical rails 1a, 1b and the horizontal rail 2 and passes through the branching point, that is, the switching point 3, the following procedure is performed.

When the vertical carrier 10 passes through the switching point 3, the carrier 10 is moved to the vertical rail 1.
From either direction a or 1b, the transport path A passes through the straight rail 4 in the directions of arrows E and F in the figure.

When proceeding horizontally from above or from horizontally upwards, the switching point 3 moves in the direction of arrow C and is switched to the R rail 5, so that the carrier 10 proceeds through the R rail 5.

When moving horizontally from below, the carrier 10 is raised from the vertical rail 1b in the direction of arrow E until it passes the straight rail 4 and stopped, and after the switching point 3 is switched to the R rail 5, the carrier 10 is moved upward. Due to free fall, it passes through the conveyance path B, that is, the R rail 5, and advances toward the horizontal rail 2 in the direction of arrow G.

When moving downward from horizontal, switch switching point 3 to R rail 5 in the same way as above, and move carrier 1 to the position passing R rail 5.
Raise 0 and stop, move switching point 3 to arrow D
direction, switch to the straight rail 4, and let the carrier 10 fall freely onto the vertical rail 1b.
Proceed to.

In this way, in a conveyance system using a linear motor, the carrier 10 can easily move straight and change direction at the branch point between the vertical conveyance path A and the horizontal conveyance path B by switching the switching point 3. , the automatic conveyance system between upper and lower floors can be carried out at high speed and in a manner with accurate stopping position.

(g) Effects of the invention As explained above, the invention has the effect that the direction of the conveyor at the branch point between the vertical rail and the horizontal rail can be easily changed using a simple mechanism.
