Abstract

PURPOSE:To improve efficiency in the conveying device of a chart, etc., of a general hospital by branching plural sub-conveying means with abnormality detecting means from a main conveying means and stopping the advance of an object to be conveyed to a sub-conveying means in which abnormality is detected. CONSTITUTION:By inputting a destination with an operation panel 39 and as an advance key is operated, a CPU 160 outputs the destination to a main control part 151. Thereupon, the main control part 151 confirms whether the sub- conveyor of the corresponding destination is down or not and output the result to the CPU 160 which has fed the destination. Thereby, when the CPU 160 received a signal indicating the down condition of the destination from the main control part 151, it gives an indication 'unable to advance because of downed destination' to the indication part of a control panel 39 while stopping the movement of a case which is set in a case take-out/feed part. By this structure, efficiency can be improved.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention is useful for transporting medical records, slips, blood, Ringer's solution, etc. in general hospitals, etc., and for transporting mail, etc. at post offices, etc. The present invention relates to a conveyance device used for conveyance, etc.

(Prior Art) Conventionally, for example, in a general hospital, medical records, slips, heavy items, etc. are delivered and transported between the medical affairs department and the examination room. The transportation methods include transporting medical records separately by a case conveyor, slips by an air chute, and heavy items by a vertical conveyor, or medical charts, slips, heavy items, etc. by the same transport device using a self-propelled vehicle. There is a method of transportation.

In the former case, the conveyance speed can be set depending on the article being conveyed. However, since multiple conveyance devices of different types are used, a large exclusive area is required. Air shooters can transport medical charts, slips, etc. at high speed, but it is difficult to transport them at the same time.

In the latter case, one model is efficient. However, there is a limit to the transport speed.

Therefore, as a solution to the above-mentioned problems, a conveying device using a linear motor has been considered (see Japanese Patent Application No. 109387/1987).

However, such conveyance devices are large in size and tend to be more prone to breakdowns than smaller systems. Therefore, in the event of a partial failure of the device or an accident,
The entire device had to be brought down (stopped), resulting in poor efficiency.

(Problems to be Solved by the Invention) As mentioned above, the disadvantage of having to stop the entire device in the event of a partial failure or accident, resulting in poor efficiency, is eliminated. An object of the present invention is to provide an efficient conveying device that can operate without using only that part when a partial failure or accident occurs.

[Structure of the Invention] (Means for Solving the Problems) The conveyance device of the present invention includes a main conveyance means for conveying an object, and a desired object from among the objects conveyed by the main conveyance means. A plurality of sub-conveyance means that branch out and convey, a detection means that detects the presence or absence of an abnormality in these sub-conveyance means, and when an abnormality in one of the sub-conveyance means is detected by this detection means, a sub-conveyance means that causes the abnormality is detected. It consists of a means for not starting the conveyed object to the conveying means.

(Operation) According to the present invention, when an abnormality in one of the sub-transport means is detected, the object to be transported is not launched to the sub-transport means in which the abnormality occurs.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Moreover, the storage case 6a moved to the stage 52c is
It is moved to the case take-out supply section 40 via the stage 52d1 and the vertical conveyance path 74b.

At this time, arrival information (starting station, name of destination) of the storage case 6a is provided on the display section 39b. As a result, medical records and the like can be delivered using the storage case 6a supplied to the case removal and supply section 40.

In addition, the storage case 6a that stores the medical records etc. launched from the predetermined station 14 as described above is placed on the main transport path 4.
When the corresponding destination station 14 goes down while the storage case 6a is being transported, the main control unit 151 changes the starting station of the storage case 6a to the arrival station. Then, the arrival process is performed as described above, and the case is returned to the case retrieval supply unit 40 in the corresponding sub-transport path 18 of the starting station 14, and the display unit 3 in the operation unit 39
9b indicates that the destination station is down.

Further, when the corresponding destination station 14 goes down before the storage case 6a storing medical records etc. is supplied to the main conveyance path 4 after performing the above-mentioned start processing, the CPU 151 removes and supplies the storage case 6a. Return to section 40.
