Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to improvements in evacuation and recovery control of a conveyor in a linear motor car conveyor or the like.

A transport system using a linear motor car has a plurality of stators along the transport path (hereinafter referred to as rails), a secondary conductor is provided on the transport body (hereinafter referred to as carrier), and the magnetic force generated by the excitation of the stators. The driving force induced in the secondary conductor by this action causes the carrier to travel on the rail.

Generally, a stator is installed at each station that has an input/output port for conveyed items, and the carrier driven by the station is transported to the next stator without receiving any external driving force, and is then accelerated again by the next stator. or be stopped at the station.

As described above, the carrier can be transported from a predetermined station to a target station by giving start and stop commands from the controller to the stator provided for each station.

In the case of a financial institution, the station is incorporated into a mechanism such as a cash insertion machine, a cash dispensing machine, a cash storage machine, etc., and the carrier is evacuated from the rail and returned to the rail by a lift mechanism or the like.

In the linear motor car transport system as described above, the time required for evacuation and recovery operations of the carrier cannot be ignored in terms of transport efficiency, and there is a desire to shorten the time.

[Conventional technology]

An example of a conventional evacuation/recovery operation will be described below.

A stator 2 is composed of an acceleration/deceleration motor, a stop motor, etc., and is driven by a station controller in the station. This stator 2 is incorporated into a cash insertion machine, a cash storage machine, etc. together with a lift mechanism.

Further, reference numerals 8a, 8b, . . . , 8d are rail elements, which are provided at four locations on the rail at the stop position of the station, and the carrier is supported by the rail elements 8 and moves (evacuates and recovers).

FIG. 2b is a sectional view of the station mechanism, showing a state in which the carrier is stopped at the station.

The lift mechanism will be explained below.

That is, the carrier is supported by the slider blocks 23 and 24 together with the rail element 8, and the gear 26 is rotated by the rotation of the lift motor M2.
The crank mechanism 25 operates to raise and lower the carrier together with the slider blocks 23 and 24 connected thereto.

In the lift operation, switch SW2 detects lift-down completion, and switch SW3 detects lift-up completion.

Reference numerals 27 and 28 refer to auxiliary rail mechanisms, which replenish the rail element 8 to allow other carriers to pass when the carrier is lifted up together with the rail element 8, and are opened and closed by the auxiliary rail motor M1 (closed at the time of replenishment). )do. Opening/closing of the auxiliary rail is confirmed by turning on/off switch SW1.

29 is the shutter, 30 is the shutter 29 and the lid 31 of the storage box 3 when the carrier has been lifted up.
M3 is a shutter motor.

That is, when the carrier is lifted up, the lid 31 of the storage box 3 is locked to the shutter 29, and the lid 31 of the storage box is opened and closed together with the shutter 29 by the shutter lid motor M3. SW4 is a switch for checking whether the shutter is open or closed.

The carrier is evacuated from the rail 1 and restored by the above mechanism.

The operation sequence of the above mechanism is as follows.

(Escape operation) After confirming that the carrier has stopped, the evacuation operation is performed in the following order.

Lift up (evacuation movement) Auxiliary rail closed (replenishment) Shutter flap open (Recovery operation) The secondary operation is performed in the following order with a start command.

Shutter closing Auxiliary rail opening (evacuation) Lift down (recovery movement) [Problems to be solved by the invention] As explained above, the evacuation and recovery operation of the carrier consists of lift operation, auxiliary rail opening/closing operation, and shutter opening/closing operation. The three operations are performed sequentially while confirming the completion of each operation, so there is no evacuation or
There were problems in that recovery time was long and transport efficiency was poor.

[Means for solving problems]

The above-mentioned conventional problems can be solved by the conveyance device according to the present invention, which has a control means for simultaneously operating the replenishment/evacuation operation of the auxiliary conveyance path by the replenishment/evacuation means and the lid opening/closing operation by the lid opening/closing means.

[Effect]

That is, when the carrier is in the lift-up state, the auxiliary rail replenishment/retraction operation and the shutter opening/closing operation are respectively possible, and in the present invention, the auxiliary rail replenishment/evacuation operation and the shutter opening/closing operation are performed simultaneously. Therefore, evacuation and recovery time can be shortened, and transport efficiency can be improved.
