Description

[Detailed explanation of the idea]

[Overview] An automatic parts supply device that accommodates multiple parts storage boxes (hereinafter referred to as magazines) and has the function of loading and unloading the magazines to the next process, and each magazine storage section is provided with a one-way switch. This makes it possible to detect the presence or absence of a magazine and the presence or absence of parts within the magazine. [Industrial Application Field] The present invention relates to an automatic parts supply device for supplying parts in the assembly process of electronic devices. [Prior Art] A conventional parts supply device is shown in FIG. This device 1 can store a plurality of magazines 3 capable of storing parts 2 in a removable manner, and is configured to send out the magazines 3 to a work table 4 and take in empty magazines 3 again. [Problem to be solved by the invention] The above device does not detect whether the magazine is before parts are supplied or whether it is empty after parts are supplied, The disadvantage was that the location of the machine was limited and automation was not possible. The present invention was created in view of these points, and an object of the present invention is to provide an automatic parts supply device having means for detecting whether a magazine is used before parts are supplied or after parts are supplied. [Means for Solving the Problems] For this reason, the present invention is equipped with a stocker 10 having a function of storing a plurality of magazines 11 that can store a plurality of parts, and an empty magazine on the work table 14 is stored in the stocker 10. In an automatic parts supply device for feeding a magazine containing parts into a space from the stocker 10 onto the work table 14, two switches 12 and 13 are provided at each magazine storage position of the stocker 10, respectively. switch 1
At least one of the switches 2 and 13 is a one-way operation switch, and the presence or absence of the magazine 11 and the magazine 11 are determined depending on the operating state of the two switches 12 and 13.
It is characterized by detecting whether it is before or after parts are supplied. [Operation] Turning the one-way switch ON and OFF detects the insertion direction of the magazine, that is, the presence or absence of parts in the magazine, and turning the other switch ON and OFF detects the presence or absence of the magazine. [Embodiment] FIG. 1 is a diagram showing an embodiment of the present invention. In the figure, 10 is a stocker, 11 is a magazine, 1
2 and 13 are one-way operation switches, 14 is a work table, 15 is a stocker up/down mechanism, 16 is a magazine load/unload mechanism, and 17 is a control circuit. In this embodiment, two one-way operation switches 12 are provided at each magazine storage position of the stocker 10.
13 is provided, and the control circuit 17 detects the presence or absence of the magazine 11 and whether the magazine 11 is before or after supplying parts based on the operating state of the switches 12 and 13, and drives the stocker up/down mechanism 15 and the magazine load/unload mechanism 16. control and work table 14
The empty magazine above is taken into the empty space of the stocker 10, and the magazine containing parts is supplied to the work table 14. In addition, two one-way operating switches 12, which are provided at each magazine storage position, are a feature of this embodiment.
13, one of them 12 is arranged so that it is turned on only when the magazine 11 is set from the direction A, and the other one 13 is arranged so that it is turned on only when the magazine 11 is set from the direction B. In this embodiment configured in this way, the switch 1
Depending on the operation status of 2 and 13, as shown in Table 1, it is possible to determine whether there is a magazine or not, and whether it is a magazine before parts supply (magazine set from direction A) or a magazine after parts supply (magazine set from direction B). Can be detected.

[Table] FIG. 2 is a diagram showing the main parts of another embodiment. The difference between this embodiment and the previous embodiment is that whereas in the previous embodiment both switches 12 and 13 are unidirectional operating switches, only one switch 12 is a unidirectional operating switch and the other is a bidirectional operating switch. 13a. In the case of this embodiment, the relationship between the magazine status and the switch is as shown in Table 2.

[Effect of idea]

As described above, according to the present invention, it is possible to detect the presence or absence of a magazine and whether it is a magazine before parts are supplied or a magazine after parts are supplied with an extremely simple configuration, which makes it possible to automate parts supply. Therefore, it is extremely useful in practice.

[Brief explanation of the drawing]

FIG. 1 is a diagram showing an embodiment of the present invention, FIG. 2 is a diagram showing main parts of another embodiment of the present invention, and FIG. 3 is a diagram showing a conventional parts supply device. In Figures 1 and 2, 10 is a stocker, 11 is a magazine, 12, 1
3 is a one-way operating switch, 13a is a bidirectional operating switch, 14 is a work table, 15 is a stocker up/down mechanism, 16 is a magazine load/unload mechanism, and 17 is a control circuit.

Claims (1)

[Claims for Utility Model Registration] A stocker 10 having a function of storing a plurality of magazines 11 capable of storing a plurality of parts, an empty magazine on a work table 14 being taken into the empty space of the stocker 10, and a magazine storing parts. In the parts automatic supply device for supplying the stocker 10 onto the work table 14, two switches 12 and 13 are provided at each magazine storage position of the stocker 10, and one of the two switches 12 and 13 is provided. Automatic parts supply characterized in that at least one switch is a one-way operating switch, and the presence or absence of the magazine 11 and whether the magazine 11 is before or after parts supply are detected based on the operating states of the two switches 12 and 13. Device.
