Abstract

PURPOSE:To make a carrier lightweight and reduce noises due to the collision of the carrier to a stopping mechanism by providing a braking means operated by the magnetization or demagnetization of electromagnets in addition to the carrier of a cash conveyor system in a finance facility or the like. CONSTITUTION:Predetermined length rails 1a, 1b are rotatably supported by fulcrums 1c, 1d on part of a pair of rails 10, and iron plates 11a, 11b are fixed to the outsides of their free ends. Individual rails 1a, 1b are energized so as to be pulled inward by coil springs 12a, 12b. Electromagnets 14a, 14b are ar ranged at positions facing the iron plates 11a, 11b, and the rails 1a, 1b maintain a normal width L between them because these electromagnets 14a, 14b are normaly kept magnetized. When the electromagnets 14a, 14b are demagnetized due to a power failure, the rails 1a, 1b are pulled inward by the springs 12a, 12b to positions where they hit stoppers 13a, 13b, thereby the wheels 3a of a carrier 2a are pinched and braked.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to financial institutions, etc.
This patent relates to a carrier braking mechanism that can increase the flatness of the carrier during light travel and prevent noise and damage during power outages.

Recently, financial institutions and other institutions are experimenting with automatic deposit and withdrawal systems that automatically withdraw and receive cash that is handled through a single window.

This system 1 is used for multiple teller devices. , ii, automatic cash dispensing machines, and cash storage machines or windows [1 stain = 1
This system is connected to a railcar by a 17-rail, and a carrier loaded with cash travels on the rails to deposit and withdraw money.

Such systems such as 1, 1, 1 linear monitors, etc. are used, but it is desired to have a method that can run at high speeds and also prevents noise 2 and damage during emergency stops such as power outages.

[Conventional technology]

FIG. 9 and FIG. 1O are side views showing conventional examples il+ and (2) of a conveyance system using a beam near motor, and FIG. 11 is an explanatory view of FIG. 1O. The same reference numerals indicate the same objects throughout the figures.

In the conventional example (1) shown in FIG. death,
A carrier 2 carrying a secondary conductor plate 4 is arranged.

A friction brake 5 is provided at a position facing the wheels 3 of the carrier 2 and is operated by being pressed by a spring (not shown). In normal conditions, the brake OIX is attracted by a TI LIF stone (not shown) against the elasticity of the spring. 'F
is in a state of

Therefore, when the magnetic field generating coil is energized, the carrier 2 can be caused to travel due to the interaction between the traveling magnetic field generated by the L curve and the eddy current induced in the secondary conductor plate 4.

When stopping the carrier 2, magnetic field generation: Switching the energization of the 1-il in the opposite direction will stop it at a predetermined position. There is Nisa l゛ζ.

When a power outage occurs here, the excitation of the electromagnet is canceled and the friction brake 5 acts on the wheels 3 to decelerate and stop 1-
I'm letting you do it.

In addition, in the conventional example (2) in FIG.
(hereinafter referred to as PM) [), an arm 8 having a gore 1 and a tamper 7 connected to the dirt, and a stop mechanism 9 consisting of a co-driver 7+1 are provided.

Under normal conditions, p M [! is excited, and the 1-
When the arm 8 is tilted by pushing against the elasticity of the coil spring 7a and there is a power outage, the I) M6 of the stop mechanism 9 is de-energized as shown in Fig. 11.
The arm 8 is pulled by the elasticity of the handle 7a, and the carrier 20) is moved to the rubber damper 7 which has moved into the travel area.
The Ti-order conductor plate 4 is collided with -1 (stop -1).

This,
-Rear 20) Deceleration and stop 1- are performed.

[Problems to be Solved by the Invention] In the above-mentioned conventional methods, (1) a method of braking the wheels 3 of the carrier 2 with a friction brake 5, or (2) a method of stopping the carrier 2 with a rubber damper 7. In method (2), since the carrier 2 is equipped with braking mechanisms such as an electromagnetic magnet and a friction brake 5, a power supply means is required to supply power to these components, and the carrier 2 becomes heavy, which reduces the traveling speed. ing.

In method (2), the braking (deceleration, stopping) of the carrier 2 does not work effectively, and furthermore, the life is shortened due to the noise generated when the carrier 2 and the rubber damper 7 collide, and the deformation caused by the collision.

The present invention is provided outside the carrier, and the Mll of the electromagnet is
((i) This is a carrier braking mechanism that includes a braking means that is activated by de-energization to prevent the carrier from traveling, and by doing so, the problem described in -1- can be solved.

[Effect]

According to the present invention, instead of the conventional method of braking using a friction brake or colliding with a rubber damper, a braking means that is activated by excitation of an electric stone or de-energization of an electric stone is used in the evening of the carrier. provided, and by actuation of the braking means -
1- Stop the middle rear. For example, one end of a predetermined length of the rail is set as a free end, and under normal conditions, this free end is attracted by an electromagnet against the elasticity of a spring, and in an emergency such as a power outage, it can be released by de-energizing the electromagnet 1. The carrier can be braked by changing the width of the rail, or alternatively, by de-energizing the electromagnet, it can be moved and positioned within the travel area of the carrier to elasticize the flange members installed on the carrier. It is also possible to brake the speed by using multiple rollers that hold the carrier in place, which reduces the weight of the carrier and increases the speed, which requires braking means and its power supply means on the carrier side. In addition, it is maintenance-free, eliminates collision noise, and extends the life of the vehicle.
